Full textAbstract:
This study was aimed at analyzing the growth patterns of catfish (Clarias leiacanthus) through the analysis of length-weight relationships. The Condition Factor is calculated to determine the habitat conditions of the C. leiacanthus fish population. The research was carried out from October to December 2021 in the Aek Silom-lom River, South Labuhanbatu Regency. Measurement of fish length and weight and identification were carried out at the Ecology Laboratory, Faculty of Teacher Training and Education, Labuhanbatu University. Samples were captured using fishing gear in the form of fishing rods. Growth pattern analysis refers to the Linear Allometric Model (MAL), the condition factor is calculated based on relative weight (Wr) and Fulton (K). The catch during the study was 54 catfish (C. leiacanthus) obtained from Aek Silom-lom. The results of measurements against the sample obtained that the total length range (TL) is 20-31 cm, and weight (W) 81-180 g. Analysis of the linear allometric model explained that the growth pattern of catfish (C. leiacanthus) is negative allometric b=2.22 (b<3). The results of the condition factor analysis obtained a relative range (Wr) of 81.047 – 124.552 with an average of 88.01. Factor Analysis of Fulton's condition (K) found a K value of 0.84. Based on the value of the Fulton condition factor (K) it can be concluded that the waters of Aek Silom-lom are in a balanced state, and can support the life of long catfish (C. leiacanthus).

Full textAbstract:
This study aims to determine various relationships between liver, gonad and body weights of the two pipefish species caught in two breeding seasons from the Bafa Lake (Muğla) coasts between 2014 -2016. Using beach seine-net in the lake, a total of 208 pipefish specimens (79 Synathus abaster and 129 Synathus acus) were sampled. L-W relationship and Fulton condition factor were W = 2E - 0.94.01, 0.035 ± 0.009 in S.abaster specimens. Also LW relationships and condition factor were W = 8E-0.93.83 , 0.033 ± 0.01 in S. acus. On the other hand mean ± SD of HSI and GSI values were 2.18 ± 1.65 and 7.69 ± 7.12 respectively. In S.acus values 3.22 ± 3.13 and 5.49 ± 5.12 as well. The decrease in HIS and K values, provides sufficient information to claim that species in the lake spend all energy requirement obtained with proper feeding to growth and gonad development.

Full textAbstract:
The Lessepsian migrants of the family Fistulariidae, which are widely distributed in the Eastern Mediterranean coasts of Türkiye, are represented by two species, Fistularia commersonii and Fistularia petimba. This study focused on estimating various biological indices of red cornetfish Fistularia petimba Lacepède 1803, eastern Mediterranean coast of Türkiye. The biological indices determined were: FI- Fullness index, HSI-Hepatosomatic index, GSI-Gonadosomatic index, EQ-Encephalization quotient, VSI-Visceral index, IWL-Zihler index, Fulton-K: Fulton-Condition. For this study, 65 red cornetfish specimens (♀:40, ♂:23, immature: 2) caught as by-catch in the nets of commercial trawlers, operating in the study area in the winter of 2021 were studied. The estimated length-weight relationship (LWR) was W=0.0001L3.34 (R2= 0.89) and the species exhibits a positive allometric growth. The mean index (M±SD) and range values calculated from the obtained data are as follows: FI 1.05±0.13 (0.83-1.26); HSI 0.43±0.05 (0.23-0.62); GSI 1.27±0.20 (1.08-1.46); EQ 0.0024±0.0003 (0.0022-0.0025); VSI 3.14±0.39 (2.08-4.20); IWL 12.37±1.54 (4.41-20.3) and Fulton-K 0.47±0.06 (0.43-0.51). According to these results, it can be hypothesized that this Lessepsian species is well established and thrives in the eastern Mediterranean coasts of Türkiye. Although it is evaluated as the least concern category (LC) in the IUCN Red List 2013, we believe that the species has an invasive potential. Therefore, this study, in which biological index parameters were presented for Fistularia petimba, may be important in terms of fisheries management, planning measures to reduce distribution and combating invasiveness.

Full textAbstract:
Biological aspects (length frequency distribution, length-weight ratio, sex ratio, allometric growth, Fulton's condition factor) of Upogebia pusilla were studied in Tivat Saline (Tivatska solila), Boka Kotorska Bay in 2019. A total of 1,415 individuals were collected. The total length of all studied individuals ranged from 27 to 55 mm (8 and 20 mm CL), while the total weights ranged from 0.29 to 2.56 g (the total length of males ranged from 27 to 51 mm, non-ovoid and ovoid females ranged from 27 to 51 mm and 30 to 55 mm, respectively; the weights ranged from 0.29 to 2.52 g, 0.34 to 2.52 g and 0.47 to 2.56 g for males, non-ovoid and ovoid females, respectively). The overall female:male ratio was 1.2:1. Egg-shaped females were recorded from April (74.3%) to June (23.8%), with a peak in May (91.4% of all females). Males dominated in July (66.4%). The relationship between CL and W was negatively allometric in both males and females and in all sampled individuals. Fulton?s condition factor was higher only in females during the breeding season, while there were no significant differences between males and females during the rest of the year. Since this species is mainly used as live bait for commercial and sports fishermen, the results of this study would be useful for the sustainable management of this species.

We performed intensive rearing of larvae of the nase Chondrostoma nasus (L.) in a feeding experiment until 21 days from the initiation of exogenous nutrition under laboratory conditions at a temperature 26&deg;C. Two dry starter feeds (a feed for salmonids and a starter feed of the artificialplanktontype)differinginthecompositionof nutrients (50% and 60% of proteins, 12% and 16% of fat, respectively) and natural food (Artemia salina nauplii) were used. Cumulative survival rate, individual weight (w), total length (TL), specificweightgrowthrate(SWGR),specificlengthgrowthrate(SLGR)andconditionfactor(CF)wereassessed.One-wayanalysisofvariance(ANOVA)was used for statistical processing of data. High survival rate 99.3% and the highest (P &lt; 0.01) growth rate of nase larvae (TL = 22.0 mm, w = 69.2 mg) were found when feeding the natural food. The application of dry feed of the artificialplanktontyperesultedinhighersurvival(98.8%)andsignificantlyhigher(P &lt; 0.01) growth of both length and weight (TL = 17.5 mm, w = 42.5 mg) compared to the nase fed with dry feed for salmonids (survival rate 77.3%, TL = 15.9 mm, w = 24.5 mm). In the course of the experiment the value of Fulton&rsquo;s coefficientincreasedfrominitial0.57 to 0.79 in fishfedwithartificialplanktonto0.65infishfedwithnaturalfoodandto 0.61if dryfeedforsalmo-nids was used. We conclude that with an appropriate starter feed the successful intensive rearing of larval nase can be carried out under controlled conditions.

Full textAbstract:
Age composition, length-weight relationships, growth, and condition factors of the gibel carp (Carassius gibelio Bloch, 1782) were determined using specimens collected from Seyitler Reservoir between July 2005 to June 2006. A total of 149 gibel carp were observed and examined. The age composition of the samples ranged between I and VII years of age. It has been determined than 82.55% of the obtained samples are comprised of females, 16.11% is comprised of males and 1.34% is comprised of immature. The population is dominated by females able to reproduce gynogenetically. The mean fork lengths and mean weights of the population were 14.8-32.5 cm and 43.1-807.3 g respectively. The length-weight relation were calculated as W = 0.0696 L2.132, r=0.838 for females, for males W = 0.2942 L2.6417 r=0.784 and W = 0.0274 L2.9382, r=0.813 for all samples. The mean Fulton Condition Factor was calculated as 2.342 for females, 2.064 for males and 2.276 for all samples. Age-length and age-weight relations were determined according to von Bertalanffy growth equation formula. Growth parameters of the population were Lt = 48.09 [1-e-0.093(t+0.29)], and Wt=2323.62 [1-e-0.093(t+0.29)]2.9382. The growth performance index value (Ø´) was computed as 5.37 for all specimens.

Full textAbstract:
In 1981 W. Fulton and R. MacPherson introduced the notion of bivariant theory (BT), which is a sophisticated unification of covariant theories and contravariant theories. This is for the study of singular spaces. In 2001 M. Levine and F. Morel introduced the notion of algebraic cobordism, which is a universal oriented Borel–Moore functor with products (OBMF) of geometric type, in an attempt to understand better V. Voevodsky's (higher) algebraic cobordism. In this paper we introduce a notion of oriented bivariant theory (OBT), a special case of which is nothing but the oriented Borel–Moore functor with products. The present paper is a first one of the series to try to understand Levine–Morel's algebraic cobordism from a bivariant theoretical viewpoint, and its first step is to introduce OBT as a unification of BT and OBMF.

Full textAbstract:
The current research reports the length-weight relationships (LWRs) and Fulton’s condition factor (K) of three grouper species, namely: areolate grouper (Epinephelus areolatus), blacktip grouper (Epinephelus fasciatus), and honeycomb grouper (Epinephelus merra) harvested in the northern coast of Aceh, Indonesia. The fish samples were gathered from Pelabuhan Perikanan Samudera (PPS) Lampulo, Kuta Alam District, Banda Aceh, Aceh from June - December 2020. In total, 571 grouper specimens were collected during the study period (186 of E. areolatus, 205 specimens of E. fasciatus, and 180 E. merra). The total length (TL) of each fish species ranged from: 125.9-302.5 mm (mean 222.5 ± 30.3) (E. areolatus), 113.3-268.6 mm (mean 196.6 ± 26.9) (E. fasciatus) and 111.1-215.4 mm (mean 162.9 ± 21.7) (E. merra) with weight (W): 25.5-367.6 g (mean 145.8 ± 64.6) (E. areolatus), 24.0-290.9 g (mean 130.3 ± 56.2) (E. fasciatus) and 24.0-290.9 g (mean 130.3 ± 56.2) (E. fasciatus). In addition, the observed Fulton (K) condition factor and Ws values for all the three species were above 100 and 1. Furthermore, the LWRs analysis results revealed that all three fish species showed the b value of 3.0548 (r2=0.97), 3.0466 (r2=0.94) and 3.1681 (r2=0.97) for E. areolatus, E. fasciatus and E. merra, respectively, indicating that the three observed fish species had a positive allometric growth pattern and had a solid relationship between body weight and total length. This study delivers a reference point of several biological characteristics of the observed grouper species that will benefit and improve the fisheries management in the region.

This article presents an overview of clean coal technologies that promise to produce electricity with fewer emissions. The 600 MW John W. Turk Jr. power plant built by American Electric Power near Fulton is the first “ultra-supercritical” electric-generating clean coal unit in the U.S. Turk’s efficiency is 39 percent to 40 percent, versus about 35 percent for conventional plants. Turk burns roughly 11 percent less coal than a subcritical plant would need to produce the same amount of power. Less coal means fewer emissions, and what’s left – aside from carbon dioxide – is further reduced by the state-of-the-art emission control technologies. Another clean coal technology that has seen wider adoption is the circulating fluidized bed combustion (CFBC) technology. One of CFBS’ greatest advantages is that since the furnaces burn at low temperatures, it can use very low-quality fuel, such as waste piles left over from mining and even chicken litter.

A honeysuckle (Lonicera fragrantissima) shrub on the grounds of the former Plant Quarantine Station, Glenn Dale, MD, had chlorotic leaves on some shoot tips and a mild veinal chlorosis. Young leaves were triturated in buffer and rub-inoculated onto a series of potential indicator hosts. The virus incited necrotic local lesions and necrosis of the growing point in Chenopodium quinoa, etched ringspots on inoculated leaves of Nicotiana tabacum Xanthi nc, mosaic in Zinnia violacea, and chlorotic local lesions in Tetragonia tetragonioides. It did not infect any of 46 other herbaceous genera in families Cucurbitaceae, Fabaceae, Asteraceae, Solanaceae, or Brassicaceae. In gel diffusion tests with symptomatic leaves from tobacco, this virus reacted with antiserum to tobacco streak virus (TSV) HR strain, but did not react with antisera to alfalfa mosaic or with antisera to 12 viruses in the NEPO or Sobemovirus groups. Virus in leaves directly from the source shrubs, tested by enzyme-linked immunosorbent assay (ELISA), also reacted with TSV strain HF antiserum. Examination by electron microscopy of leaf dips revealed isometric particles 27 nm in diameter. The now 12-ft tall shrubs were grown from seed imported from China in 1914 (PI 40689). This species is now widely commercially available in the U.S. and grown for its fragrant late winter flowers (2). Viral-infected Lonicera spp. have been reported from Europe, Russia, Japan, and Canada (1). TSV is reported to be seed-borne in several other genera. Among other viruses reported from honeysuckle are Lonicera latent carlavirus, tobacco leaf curl geminivirus, alfalfa mosaic virus, tomato bushy stunt virus, a rhabdovirus, and an aphid transmitted virus.

Abstract There has been considerable interest in repurposing the poly ADP ribose polymerase inhibitor and purported radiosensitiser olaparib (Lynparza), with a recent dose escalation study of olaparib plus temozolomide in recurrent GBM showing good tolerance (Fulton et al 2018). Due to systemic therapy-associated caveats such as dose-limiting toxicities and blood-brain-barrier penetration, here we assess localised post-surgical delivery of olaparib from our previously developed poly(DL-lactic-co-glycolic acid) (PLGA) and poly(ethylene glycol) (PEG) (PLGA/PEG) thermo-sensitive biodegradable paste. Metabolic and clonogenic assays revealed impaired proliferation and clonal growth respectively, upon acute exposure of high-grade glioma cells to olaparib (3–5µM), an effect dramatically potentiated with 3Gy radiation. Flow cytometry of Annexin V+/Propidium iodide+ rodent and human high-grade glioma cells, revealed a significant cell proportion increase at late stage apoptosis when exposed to 2–3µM olaparib and 3Gy radiation (relative to untreated, olaparib alone or radiation alone). A high-grade glioma orthotopic allograft study is ongoing where we already observe a significant overall survival benefit of locally-delivered 10% and 20% w/w (drug:polymer ratio) olaparib via PLGA/PEG paste post-surgery with adjuvant radiotherapy, compared to surgery/oral temozolomide/radiotherapy (GBM standard-of-care) and surgery/systemic olaparib (120 days vs. 44 vs 30 respectively). A more pronounced survival benefit, as determined by the total number of long-term surviving animals, was observed with combined PLGA/PEG/olaparib/temozolomide/radiotherapy or PLGA/PEG/olaparib/etoposide/radiotherapy. RNAseq data from 10 GBM patients show significantly elevated levels of apoptosis-inducing factor-1 in 5-aminolevulinic acid (5ALA)+ fluorescence–activated cell sorted populations (i.e. purified tumour cells from the invasive margin), relative to 5ALA- cells, confirming PARP-1 activity in infiltrative tumour cells. Collectively our data supports a clinical rationale for localised olaparib delivery with adjuvant radiotherapy.

Full textAbstract:
European plum line pattern was first described in Bulgaria (1) and can now be found nearly worldwide. Characteristic symptoms in infected plum (Prunus domestica) include line and oak leaf patterns with chlorotic lines and rings in leaves. The causal agent of this economically damaging plum disease is Apple mosaic virus (ApMV). ApMV has been reported to naturally infect a number of hosts in the Rosaceae, including Rosa, Malus, and Rubus spp. as well as Humulus, Betula, and Corylus spp. in other plant families (3), but has not been reported to naturally infect plum in Turkey. In this study, disease symptoms were observed in only one local cultivar (Süt eriği) during the growing season of 2008–2009 in Amasya and Tokat provinces, situated between the Black Sea and inner Anatolia regions. Leaf samples were collected from 22 plum trees and tested by serological and molecular methods. In serological tests, double-antibody sandwich-ELISA was used with antisera to ApMV and Prunus necrotic ringspot virus (PNRSV) according to the manufacturer's (Agdia, Inc., Elkhart, IN) protocol. While none of the samples reacted positively to PNRSV antisera, 19 samples reacted positively to ApMV antisera. The presence of ApMV in symptomatic plum trees was confirmed by reverse transcription (RT)-PCR. RT-PCR was conducted with ApMV-specific primers (Forward 5′-ATCCGAGTGAACAGTCTATCCTCTAA-3′; reverse 5′-GTAACTCACTCGTTATCACGTACAA-3′) as previously described (4) to specifically amplify a 262-bp product from viral sequences. Total RNA was extracted from plum leaf samples with a modified protocol based on silica-capture (2). Using serological and RT-PCR tests, ApMV was detected in all 19 samples that showed virus symptoms, but not from symptomless plants. To our knowledge, this is the first record of the presence of European plum line pattern in Turkey and provides a starting point for investigation of the incidence of ApMV in plum orchards of Turkey.

Full textAbstract:
Growth rate of sterlet larvae and juveniles during 2008 and 2009 was studied under experimental and farming conditions in the Czech Republic. The embryos hatched when reaching a mean total length (TL) of 9.0 mm. Larvae were fed by living food, with a gradual transition to dry diet. The exogenous feeding and the larval period of ontogeny started at DAH 9 (day after hatching) reaching TL of 15–17 mm accompanied by melanin plug exclusion. Towards the end of larval period (DAH 39–43, TL 50–58 mm), the embryonic finfold disappeared and the formation of fin apparatus was nearly completed. During the larval and early juvenile development, daily increments of TL and weight (w) ranged between 0.33–4.23 mm.d−1 and 0.0018–1.6400 g.d−1, respectively. The specific growth rate (SGR) ranged from 25.65 to 2.73 %.d−1. Growth intensity and length parameters are similar to the Starry sturgeon, lower than those of the Siberian sturgeon and Russian sturgeon and significantly lower than at Beluga sturgeon. Sterlet’s Fulton weight condition factor (FWC) was higher than in the Siberian and Starry sturgeon. The development was also observed on the basis of morphological changes. The larval development could be divided into six steps.

His 1930s campaign for rearmament and opposition to appeasement, his ‘finest hour’ in 1940, and his 1946 ‘Iron Curtain’ speech at Fulton, Missouri, secured for him on both sides of the Atlantic an almost unparalleled relevance in the rhetoric of the following forty years' Cold War. To Western politicians of this period, his career offered pertinent ‘lessons’ – particularly the need to appear resolute in the face or threat of aggression. To this was added the fact that his magnificent command of English made him a rich quarry of quasi-prophetic quotes for an endless succession of political speeches and journalistic articles.

Full textAbstract:
Hedinichthys yarkandensis (Day, 1877) has been highlighted in research and evaluated as a class II key protected aquatic wildlife in Xinjiang Uygur Autonomous Region. To enhance the study of fish resources in the Hotan River, further germplasm conservation of fishery resources specific to the Tarim River Basin should be carried out, and the development of the aquatic seed industry should be promoted. A total of 1275 H. yarkandensis individuals were collected from 2020–2021. Fish ecological methods were used to explore the population ecological characteristics and ecological habits of H. yarkandensis. We found that the age of H. yarkandensis ranged from one to seven based on lapillus otoliths, and two-plus individuals accounted for more. The age structure composition reveals stable genetic performance and good population fecundity. The fitting correlations of standard length and body weight reveal that H. yarkandensis in the Hotan River is a uniformly growing fish. The ratio of females to males is 0.87:1. The Fulton condition index of males was slightly higher than that of females due to individual miniaturization. The comparative study found that the growth parameters of the Hotan River population (L∞ = 302.772, W∞ = 310.8450, t0 = −0.4608) were higher than those of the other groups. The feeding demand of H. yarkandensis in the Hotan River was guaranteed because the effect of human activities was small in the watershed area and the watershed ecosystem was more stable, which resulted in stable germplasm resources in the Hotan River population.

Full textAbstract:
Euphorbia pulcherrima (poinsettias) are commonly infected with Poinsettia mosaic virus (PnMV), which resembles the Tymovirus genus in its morphology and viral properties (2) but is closer to the Marafivirus genus at the sequence level (1). Symptoms induced by PnMV range from leaf mottling and bract distortion to symptomless (2). The presence of PnMV in plants imported into New Zealand had never been proven. Leaves of 10 E. pulcherrima samples and six samples from other Euphorbia spp. (E. atropurpurea, E. lambii, E. leuconeura, E. mellifera, E. milii, and E. piscatorial) were collected in the Auckland area, North Island in 2002. Isometric particles of 26 to 30 nm in diameter were observed with electron microscopy in 3 of 10 E. pulcherrima samples. These three samples produced systemic chlorosis and crinkling symptoms on mechanically inoculated Nicotiana benthamiana, which tested PnMV positive by double-antibody sandwich (DAS)-ELISA (Agdia, Elkart, IN). No particles or symptoms on N. benthamiana were observed with the other Euphorbia spp., which were also PnMV-negative by DAS-ELISA. A reverse transcription-polymerase chain reaction (RT-PCR) was developed to further characterize PnMV. Specific primers were designed from the PnMV complete genome sequence (Genbank Accession No. AJ271595) using the Primer3 web-based software (4). Primer PnMV-F1 (5′-CCTGTATTGTCTCTTGCCGTCC-3′) and primer PnMV-R1 (5′-AGAGGAAAGGAAAAGGTGGAGG-3′) amplified a 764-bp product from nt 5291 of the 5′-end RNA polymerase gene to nt 6082 of the 3′-untranslated region (UTR). Total RNA was extracted from leaf samples using the Qiagen Plant RNeasy Kit (Qiagen Inc., Chastworth, CA). RT was carried out by using PnMV-R1 primer and MMLV reverse transcriptase (Promega, Madison, WI). The PCR was performed in a 20-μl volume reaction containing 2 μl cDNA, 1× Taq reaction buffer, 1.5 mM MgCl2, 0.2 mM dNTPs, 0.2 μM PnMV-F1 primer, and 1 U of Taq polymerase (Promega) with a denaturation step (94°C for 5 min), 30 amplification cycles (94°C for 30 s; 55°C for 30 s; 72°C for 1 min), and a final elongation (72°C for 5 min). The sequence of the RT-PCR product (Genbank Accession No. DQ462438) had 98.7% amino acid identity to PnMV. PCR products were obtained from two of three PnMV ELISA-positive E. pulcherrima and three of three PnMV ELISA-positive symptomatic N. benthamiana. The failure to amplify the fragment from all ELISA-positive PnMV is likely because of the presence of inhibitors and latex in E. pulcherrima (3) that make the RNA extraction difficult. Thus, while RT-PCR may be useful for further characterizing PnMV isolate sequences, ELISA may be more reliable for virus detection. In conclusion, to our knowledge, this is the first report of PnMV in E. pulcherrima but not in other Euphorbia spp. in New Zealand. E. pulcherrima plants have been imported into New Zealand for nearly 40 years, and the virus is probably widespread throughout the country via retail nursery trading. References: (1) B. G.

The length – weight relationship (LWR), condition factor (K), sex ratio, gonadosomatic index (G S I) and hepatosomatic index (H S I) of 412 specimens of Pseudotolithu s s enegalensis (Valenciennes, 1833) from Tombo , a coastal fishing community in the western rural district of Sierra Leone were studied for twelve months . Samples used for the study were collected from the catches of artisanal fishers and measurement s of length and weight of samples were done in situ using the facilities of the Ministry of Fisheries and Marine Resources. Samples for the reproductive study were preserved in an ice box and taken to the laboratory of the Department of Aquaculture and Fisheries Management, Njala University , Sierra Leone for analysis. The parameters "a" and "b" of the length - weight relationship were estimated using the equation described by Ricker ( W = aL b ) while the condition factor was calculated using Fulton`s equation (K = W1 00 / L 3 ) . The reproductive biology of the fish was estimated using Gonadosomatic index ( GSI ) and Hepatosomatic index ( H S I ) . The combined LWR for both sexes showed that a, b and r values were – 2.57 , 3. 3 5 and 0. 899 , respectively. The r – values obtained show a strong linear relationship between the length and weight of the species. The length - weight relationship indicated allometric growth for P . senegalensis in the study area. The condition factor (K) varied from 0.64 – 1.0 ; this may be attributed to environmental conditions of the water . The species clearly exhibited a positive allometric growth pattern ( tα ( 2) , 0.05, 411 > 1.965) . The sex ratio of males to females was 1:1. 15 and was not significantly different from the expected 1:1 ratio. Estimation of GSI and HSI was carried out from December, 2010 to May, 2011 to determine the spawning behaviour of P. senegalensis . The mean GSI obtained indicate d that March and April , respectively are the two peak spawning period for the species . Gonado somatic index ranged between 1.1 % and 2.8% for the females. The results of this study revealed that P. senegalensis doe s not have obligatory spawning month but exhibit multiple spawning behaviour. T he length - w eight relationships and condition factor of the study indicated that the fish were thriving very well in the coastal water of Sierra Leone. Sustainable management of the species , therefore , require s that the environment be protected against anthropogenic pollution and imposition of closed fishing season especially during the t wo peak spawning period is recommended to enable the species recruit effectively.

Full textAbstract:
Apple mosaic virus (ApMV; family Bromoviridae, genus Ilarvirus) is one of the oldest and most economically important viruses of apples (Malus × domestica Borkh.) (1,3). Yield losses may vary from negligible to as much as 50%, depending on the affected cultivar. Although ApMV is found worldwide and occurs naturally in more than 65 plant species (1), it has not been reported to occur in Alaska. In July 2011, noticeably bright yellow mosaic leaves were observed on apple ‘Valentine’ and its rootstalk ‘Ranetka’ from an apple orchard in Wasilla, AK. Leaves were collected and assayed by reverse transcription (RT)-PCR using ApMV-specific primers (2) and total RNA extracted with buffer modifications to RNeasy Plant Mini Kit (Qiagen, Valencia, CA). Briefly, 50 mg of leaf tissue was ground in liquid nitrogen and 450 μl of SE buffer (0.14 M NaCl, 2 mM KCl, 2 mM KH2PO4, 8 mM Na2HPO4·2H2O [pH 7.4], 0.05% vol/vol Tween-20, 2% wt/vol polyvinylpyrrolidone 40, 0.2% wt/vol ovalbumin, 0.5% wt/vol bovine serum albumin, and 0.05% wt/vol sodium azide) was added, and after vigorous vortexing, 80 μl of the mixture was added to 400 μl of RLT buffer supplied by the kit and then processed as directed by the manufacturer (4). Direct sequencing of the predicted ~260-bp PCR product resulted in 97 to 98% nucleotide identities to ApMV accessions in GenBank when analyzed by BLAST. To determine the distribution and incidence of infection in the Wasilla orchard, all 118 apple trees (99 cultivars) were then sampled and assayed serologically by double-antibody sandwich-ELISA with ApMV antiserum according to the manufacturer's protocol (Agdia, Inc., Elkhart, IN). Apple ‘Geneva Early’ and the same ‘Valentine’ tree and its rootstock tested positive for ApMV by ELISA and RT-PCR. Strong diagnostic ApMV symptoms were not apparent on the infected ‘Geneva Early’, which is typical for most commercially grown apples. No leaves were available on the ‘Ranetka' rootstock of ApMV-infected ‘Geneva Early’ for virus indexing. An additional 21 apple trees with no symptoms from an orchard in Talkeetna, AK tested negative to ApMV by ELISA. Limited natural spread of ApMV to other plants may be by pollen and seed transmission. The most prevalent mode of transmission is from ApMV-infected rootstock and grafts. It is important to obtain new propagation plant material from certified virus tested nurseries and to avoid grafting plant material containing ApMV. To my knowledge, this is the first report of ApMV in Alaska. References: (1) R. W. Fulton. No. 83. CMI/AAB Descriptions of Plant Viruses. 1972. (2) W. Menzel et al. J. Virol. Methods 99:81, 2002.

Full textAbstract:
Background Cellulolytic, hemicellulolytic, and amylolytic (CHA) enzyme-producing halophiles are understudied. The recently defined taxon Iocasia fonsfrigidae consists of one well-described anaerobic bacterial strain: NS-1T. Prior to characterization of strain NS-1T, an isolate designated Halocella sp. SP3-1 was isolated and its genome was published. Based on physiological and genetic comparisons, it was suggested that Halocella sp. SP3-1 may be another isolate of I. fronsfrigidae. Despite being geographic variants of the same species, data indicate that strain SP3-1 exhibits genetic, genomic, and physiological characteristics that distinguish it from strain NS-1T. In this study, we examine the halophilic and alkaliphilic nature of strain SP3-1 and the genetic substrates underlying phenotypic differences between strains SP3-1 and NS-1T with focus on sugar metabolism and CHA enzyme expression. Methods Standard methods in anaerobic cell culture were used to grow strains SP3-1 as well as other comparator species. Morphological characterization was done via electron microscopy and Schaeffer-Fulton staining. Data for sequence comparisons (e.g., 16S rRNA) were retrieved via BLAST and EzBioCloud. Alignments and phylogenetic trees were generated via CLUTAL_X and neighbor joining functions in MEGA (version 11). Genomes were assembled/annotated via the Prokka annotation pipeline. Clusters of Orthologous Groups (COGs) were defined by eegNOG 4.5. DNA-DNA hybridization calculations were performed by the ANI Calculator web service. Results Cells of strain SP3-1 are rods. SP3-1 cells grow at NaCl concentrations of 5-30% (w/v). Optimal growth occurs at 37 °C, pH 8.0, and 20% NaCl (w/v). Although phylogenetic analysis based on 16S rRNA gene indicates that strain SP3-1 belongs to the genus Iocasia with 99.58% average nucleotide sequence identity to Iocasia fonsfrigida NS-1T, strain SP3-1 is uniquely an extreme haloalkaliphile. Moreover, strain SP3-1 ferments D-glucose to acetate, butyrate, carbon dioxide, hydrogen, ethanol, and butanol and will grow on L-arabinose, D-fructose, D-galactose, D-glucose, D-mannose, D-raffinose, D-xylose, cellobiose, lactose, maltose, sucrose, starch, xylan and phosphoric acid swollen cellulose (PASC). D-rhamnose, alginate, and lignin do not serve as suitable culture substrates for strain SP3-1. Thus, the carbon utilization profile of strain SP3-1 differs from that of I. fronsfrigidae strain NS-1T. Differences between these two strains are also noted in their lipid composition. Genomic data reveal key differences between the genetic profiles of strain SP3-1 and NS-1T that likely account for differences in morphology, sugar metabolism, and CHA-enzyme potential. Important to this study, I. fonsfrigidae SP3-1 produces and extracellularly secretes CHA enzymes at different levels and composition than type strain NS-1T. The high salt tolerance and pH range of SP3-1 makes it an ideal candidate for salt and pH tolerant enzyme discovery.

Full textAbstract:
Biometric indices of Pomadasys jubelini from Obuama Creek, Rivers state, Nigeria were investigated using length frequency distributions (LFDs), length-weight relationships (LWRs), length-length relationships (LLRs), condition factors (allometric, KA, Fulton’s, KF and relative, KR). Specimens were captured in a stretch of the creek from March to September 2019. A total of 229 specimens were examined with the total length (TL) and weight (W) ranging from 8.7 to 50.4 cm and 8.7 to 834.5 g respectively. The standard length (SL) ranged from 5.3 to 46.8 cm, fork length (FL) was between 6.5 to 48.7 cm and the girth length (GL) varied from 4.7 to 38.7 cm. The relationships of weight-length showed a negative allometric growth pattern with a value of "b" of 2,666. Fulton's condition factor (KF) ranged from 0.10 to 5.45, with an average of 1.21±0.66 indicating perfect wellbeing for the species. The LLR's allometric coefficient ' b ' between TL vs. FL and TL vs. GL showed positive allometric growth, while SL vs. FL, SL vs. TL, SL vs. GL, and GL vs. TL showed negative allometric growth, although the values were close to 1. These findings also provided some new and updated information on some of the morphometric characters of Pomadasys jubelini in Obuama Creek that could be useful for fisheries management and fish species protection measures in the creek and adjacent habitats.

Sampling was carried out in June and July 2023 in the new moon and full moon phases at each river mouth. The fishing gear uses a beach seine 20 m long with a net height of 2 m. Analysis of condition factors and growth patterns using a length-weight relationship approach. Fulton's Condition Factor: K=100W/L3 Where K is the condition factor, W is the weight of the fish and L is the length of the fish (total length). Relative condition factor: Kn=W/Ŵ, where W is the weight of the fish and Ŵ is the estimated weight of the fish from the analysis of the length-weight relationship. Allometric and isometric growth patterns with length-weight relationship analysis: W=aLb where W is the weight of the fish (g), L is the length of the fish (cm), a and b are constants. During the research, 43 fish species were obtained and 15 of them were classified as important species whose presence was ≥1% relative abundance. Fulton's K obtained ranged from 0.69-1.76, the lowest species was 0.69 Stolephorus commersonnii and the highest was 1.76 Neovespicula depressifrons. The Kn value obtained for almost all species was ≈ 1.0, except for Sillago sihama, which was much smaller, namely 0.77. The value of the constant b relationship between length and weight varied between 2.22 in Caranx ignobilis and 3.9 in Ambassis gymnocephalus. The growth pattern is isometric for six species, negative allometric for four species, and positive allometric for five species.

Full textAbstract:
The Japanese beetle, Popillia japonica (Coleoptera: Scarabaeidae), was introduced into the United States in New Jersey in 1916 and now commonly occurs in the eastern and mid-western United States. The Japanese beetle has a wide host range and feeds on more than 300 plant species within 79 families (2), but it has not been reported to be a vector of plant viruses. Southern bean mosaic virus (SBMV; genus Sobemovirus) and Bean pod mottle virus (BPMV; family Comoviridae, genus Comovirus) are transmitted by several species of leaf-feeding beetles in the families Coccinelidae and Chrysomelidae (1). Japanese beetles, collected in northwestern Arkansas with a JB Jumbo insect trap (Great Lakes IPM, Inc., Vestaburg, MI), were tested to determine if they are able to transmit SBMV and BPMV. The beetles were given a 24-h acquisition access (individually in plastic petri dishes) to detached trifoliolate leaves of Phaseolus vulgaris ‘Black Valentine’ systemically infected with either BPMV or SBMV. Beetles that had fed on the infected bean leaves (as evidenced by feeding damage to the leaves) were caged individually in clear plastic cups on healthy ‘Black Valentine’ bean seedlings for a 24-h transmission access period. The test plants were grown in the greenhouse for 2 weeks after which they were evaluated for virus infection. In the first trial, BPMV was not transmitted (0 of 11 bait plants with feeding damage), whereas SBMV was efficiently transmitted (6 of 6 bait plants with feeding damage) as determined by agar-gel double-diffusion serology of test plants using polyclonal antibodies to SBMV and BPMV. In a second trial, with a different set of beetles, the transmission rate for BPMV was 3 of 46 (6.5%) and 33 of 43 (77%) for SBMV, and the test plants were evaluated for virus infection using Protein A ELISA. The higher transmission efficiency of SBMV by Japanese beetles when compared with BPMV is characteristic of these two viruses when they are transmitted by other leaffeeding beetles (1). These results are in contrast to an earlier report that Japanese beetles were not able to transmit BPMV from infected soybeans to healthy soybeans in Illinois (3). To our knowledge, this is the first report that the Japanese beetle, an introduced insect with a wide host range in the United States, is a vector of plant viruses. References: (1) J. P.

Full textAbstract:
Apple mosaic virus (ApMV) has been reported to naturally infect a number of hosts in the Rosaceae family including Rosa spp., Malus spp., and Rubus spp. etc., as well as several hosts such as Humulus spp. and Betula spp. in other plant families (2), but has not been reported to naturally infect Fragaria spp. although it has been grafted into Fragaria spp. (1). In an attempt to develop a detection method for strawberry leafroll as part of an overall strategy to develop diagnostics for all reported virus and virus-like diseases of strawberry, double-stranded RNA (dsRNA) was extracted and cloned as described elsewhere (3) from a single-leafroll-infected plant of Fragaria vesca ‘UC-5’ (CFRA no. 9026 maintained at the USDA-ARS National Clonal Germplasm Repository [NCGR] in Corvallis, OR). Newer leaves on the plant had a chlorotic peacock pattern with a few leaves exhibiting a downward leafroll. The dsRNA pattern suggested possible infection with a crinivirus and an ilarvirus. A database search (BLAST at the National Center for Biotechnology Information) showed that clones with sequence homology to two criniviruses (Strawberry pallidosis associated virus [SPaV] and Beet pseudo-yellows virus [BPYV] as well as ApMV) were obtained from this leafroll-infected plant. Sequences of the three viruses from this plant have been deposited in GenBank (Accession Nos. AY854050, AY854051, and AY854052 for ApMV, BPYV, and SPaV, respectively). The sequence obtained for the strawberry isolate of ApMV represents part of RNA 3 and covers the majority of the coat protein (CP) gene. The nucleotide sequence identity of the CFRA 9026 isolate with the CPs of other ApMV isolates range from 87 to 91% and the amino acid sequence identity ranges from 79 to 88% with similarities ranging from 84 to 94%. Two sets of primers were designed to amplify fragments of ApMV from strawberry (ApMV-str) and one set of degenerate primers to amplify ApMV from several hosts. With the ApMV-str specific primers, we were able to detect ApMV from strawberry but not from rose, whereas with the degenerate primers, we were able to detect ApMV in strawberry and rose. Amplicons obtained with all three sets of primers were sequenced and were identical to the sequence obtained during the cloning process. In addition, polyclonal antibodies were used to trap ApMV from infected strawberries onto polystyrene immunoassay plates (NUNC, Rochester, NY). After washing, reverse transcription (RT) reactions were carried out in these wells and used in polymerase chain reaction (PCR). The sequence of the amplicons obtained were ApMV-specific as determined by sequencing. At this time, only the leafroll infected plant from the collection at the NCGR in Corvallis, OR has been tested. To our knowledge, this is the first characterization of a virus associated with strawberry leafroll disease, and development of the RT-PCR test will allow for detection of this virus in field samples to determine its distribution and importance in strawberry production.

In this study, length-weight relationship (LWR), length- length relationship (LLR) and condition factor (K) of Angora loach, Oxynoemacheilus angorae were determined. A total of 103 specimens were sampled from Kılıçözü Stream in 2014. The length and weight of specimens were ranged 3.5-9.8 cm and 0.38-6.58 g, respectively. Length-weight relationships for female, male and all samples were found as W= 0.01056.TL2.896 (r²= 0.923), W= 0.00963.TL2.940 (r²= 0.978) and W= 0.00987.TL2.929 (r²= 0.963), respectively. LWRs indicated an isometric growth in female, male and all samples. The values of Fulton’s condition factor (K) ranged from 0.699 to 1.246 for females and from 0.654 to 1.072 for males. All length-length relationships were statistically significant.

Samples of invasive cyprinid fish, the Prussian carp (Carassius gibelio), were collected by fyke nets in Leszczynskie Lakeland (Poland) during the summer and autumn, 2010, and during the spring, 2011. All captured fish were females. For each fish, the total weight (W,g) and the standard length (L,cm) were measured and Fulton’s condition factor (KC=100 W/L3) was computed. Graphical investigation and the Mann-Whitney-Wilcoxon test showed statistically significant location shift of the KC distribution from summer to autumn (upward) and from autumn to spring (downward). Relationship between total weight and standard length was described with the mean growth curve E(W∣L)=aLb. Seasonal parameters (a and b) were estimated with a nonlinear regression approach, that is, numerical optimization methods. Growth was allometric in summer and autumn and isometric in spring. The differences between summer and autumn growth curves and between autumn and spring growth curves were statistically significant. The seasonality exhibited by the condition factor and the growth curve may be due to different spawning, breeding, and feeding activity in the different seasons and to variable environmental conditions.

Full textAbstract:
The present study aims to address various aspects of the biology and distribution of turbot based on isometric data from landings at authorized ports during the period 2017-2022. By synthesizing and analyzing data from turbot fishing, we gain insights into the species' history, distribution, and life cycle, which is crucial for science and beneficial for fisheries management. The study focuses on: distribution, length-weight relationship, and condition factor of turbot. Data were collected from authorized Bulgarian ports in the Black Sea during 2017- 2022. Samples were taken from 4719 fish. The average total length and weight of the fish were 52.63±6.12 cm and 2600±910 g, respectively. The length-weight relationships were determined using the following equations: 2017: W = 0.02L2.98, n = 566 (R2 = 0.88); 2018: W = 0.04L2.80, n = 783 (R2 = 0.85); 2019: W = 0.34L2.25, n = 713 (R2 = 0.71); 2020: W = 0.02L2.90, n = 926, (R2 = 0.89); 2021: W = 0.02L2.93, n = 928, (R2 =0.88); 2022: W = 0.002L3.55, n = 803, (R2 =0.86); 2017-2022: W = 0.05L2.76, n= 4 719, (R2 =0.74). The reproductive period of turbot in the Black Sea is between April and June. The condition factor during the period 2017-2022 varied as follows: 1.74, 1.86, 1.75, 1.74, 1.74, 1.91. The overall average value of the Fulton’s condition factor during the study years was above one, indicating the good status of the turbot population (Psetta maxima) in the Bulgarian waters of the Black Sea.

Full textAbstract:
Schizothorax esocinus, a nutrient-rich food fish offered in Asian countries, is rapidly declining due to severe fishing pressure and pollution in its wild environment, requiring active conservation strategies. Our study examined 196 specimens to elucidate critical biological parameters including sex ratio, length-weight relationships (LWRs), Fulton's condition factor (K) and morphometric-meristic parameters. The general sex ratio was not substantially departed from the predicted value of 1 : 1, with the exception for the month of May, where χ2 = 4.15 which is greater than the calculated value of 3.84. The correlation between the length and weight was reported as Log W = 0.134209 + 2.5218 log L for males, Log W = 0.19173 + 2.6751 log L for females and Log W = 0.162116 + 2.594 for combined sexes. Schizothorax esocinus demonstrated a negative allometric growth as indicated by the allometric parameter b for the LWR. The two sexes showed no significant differences in morphometric measures. So, this study included combined-sex regression analysis. These comprehensive findings highlight the critical need for conservation efforts in India and neighbouring countries to preserve this valuable fish stock for future generations.

Canadian Journal of Fisheries and Aquatic Sciences 46, S1 (1989): s125—s133. http://dx.doi.org/10.1139/f89-284.
Full textAbstract:
The nutritional status of haddock (Melanogrammus aeglefinus) larvae was evaluated during May 1986 over a grid of stations exhibiting variable hydrographic conditions in southwestern Nova Scotia. Over the shallow, wellmixed regions of both the nearshore and western cap of Browns Bank, post-yolk sac haddock larvae exhibited below-average values of Fulton's K ((W/SL3) × 100, W = weight; SL = standard length) with a correspondingly high proportion of larvae in poor condition (> 70%). Conversely, larvae in good condition predominated in the deeper, stratified waters on the eastern cap of the Bank and at off-bank stations to the north along the 100-m isobath. These results agree with published field studies that used either histological or biochemical criteria to evaluate larval condition. Larvae in poor condition also exhibited surface-skewed and frequently bimodal depth profiles in contrast with the unimodal profiles centred at middepth of larvae in good condition, a result consistent with the hypothesis that buoyancy increases in starving larvae. The typically low correlation between larval abundance and recruitment may arise from use of abundance data uncorrected for the proportion of larvae in poor condition. Prorating larval survey data by using proxy variables such as stratification intensity may ultimately increase their predictive utility.

Full textAbstract:
Abstract Background: TNBCs in patients (pts) who are germline BRCA wild type (gBRCAwt) may show homologous recombination deficiency and genomic instability, resulting in a BRCA-like phenotype. The PARTNER Trial tested olaparib in combination with neoadjuvant carboplatin and paclitaxel in pts with TNBC (gBRCAwt). Methods: Pts with TNBC diagnosed locally were confirmed centrally with immunohistochemistry for ER, PR, HER2 and EGFR, CK5/6 and AR to define basal-like TNBC, before entry to the PARTNER trial. Pts were gBRCAwt. Tumours were assessed for tumour infiltrating lymphocytes (TILs). Pts were randomised 1:1 to research (R) and control arms (C). Pts received neoadjuvant carboplatin AUC 5, day(d) 1, with paclitaxel 80mg/m2 d1, 8, 15, every (q) 3 weeks (w), x 4 cycles(cy), +/- olaparib 150mg bd, po, d3-14 q 3w. Then all pts had 3cy of anthracycline chemotherapy before surgery. Primary endpoint was pathological complete response (pCR), and secondary endpoints included event-free survival (EFS), and overall survival (OS). A total of 454 patients were needed to attest 90% power with 5% significance assuming pCR rate of 50% in C and 65% in R. Results: From Sept 2016 to Dec 2021, 559 pts with TNBC (gBRCAwt) were randomised at 29 UK centres. Data cut-off was 30/11/23 with median (med) follow-up of 38 months (m). There were 276 R and 264 C pts in the intention-to-treat population. Pt and tumour characteristics were balanced between the arms: med pt age 49 years; 95% ECOG 0; 36% previous oophorectomy or post-menopausal; 95% tumour size ≤50mm; TILS score ≥60% in 22%. In R, 88% received at least 80% of the planned olaparib dose. More than 90% of patients in both R and C received at least 80% of the planned carboplatin (R 96% and C 94%) and paclitaxel (R 100% and C 99%) doses.Of 543 pts, 141 (51.1%) in R and 140 (52.4%) in C had a pCR with a difference of -1.3% (95% CI -9.7% to 7.0%, p-value=0.753). Percentage of pts with pCR increased with increasing TILs; pCR rate was 32% with TILs 0-10%, increasing to 67% with TILs 90-100%. Estimated EFS at 36 months (m) was 80% in R and 79% in C (log-rank p&gt;0.9); estimated OS at 36m was 90% in R and 87.2% in C (log-rank p=0.8). Estimated 36m EFS rate was 90.4% (95% CI, 86.4 to 94.5) in pts with pCR and 70% (95% CI, 64.2 to 76.2) in pts with non-pCR (HR=0.3, 95% CI 0.2 to 0.4; p &lt; 0.001). Estimated 36m OS was 95.7% (95% CI, 93.0 to 98.5) in pts with pCR, and 83% (95% CI, 78 to 88.2) in pts with non-pCR (HR=0.2, 95% CI 0.1 to 0.3; p &lt; 0.001). More events and deaths were observed in non-pCR pts compared to pCR pts regardless of the treatment received. Conclusions: Neo-adjuvant olaparib in the dose and schedule tested, in addition to carboplatin/taxol and anthracycline chemotherapy in basal-like TNBC in gBRCAwt patients, did not improve pCR rates, EFS or OS. Pts who achieved a pCR had significantly better EFS and OS than those with non-pCR. These results are in marked contrast to the significant benefit of olaparib in those with gBRCA mutations reported in parallel. Citation Format: Jean E.

Abstract The near-threatened Ailia coila, commonly referred to as Gangetic ailia, is a catfish species in the Ailiidae family that is indigenous to Bangladesh, Pakistan, Nepal, and India. This study describes the comprehensive explanation of life-history traits of Ailia coila, including length-frequency distribution (LFD), growth pattern (length-weight relationships, LWRs and length-length relationship, LLR), form factor (a 3.0 ), condition factors (allometric, K A ; Fulton’s, K F ; relative, K R and relative weight, W R ), size at first sexual maturity (L m ), optimum catchable length (L opt ) and natural mortality (M w ) from the Tetulia River in southern Bangladesh. Additionally, L α , a 3.0 , L m , M w and L opt from various water bodies worldwide using the existing literature were calculated in this study. A total of 316 samples were randomly collected occasionally using traditional gear for a year from July 2021 to June 2022. With an accuracy of 0.01 cm and 0.01 g, each fish’s total length (TL), standard length (SL), and body weight (BW) were measured. The group from 10.00 to 10.99 cm TL was numerically leading and the b values of LWRs indicate positive allometric growth. The a 3.0 was 0.005 and K F was the best for assessing the well-being of A. coila. Additionally, W R indicates that the habitat was imbalanced with higher predators. The calculated L m , L opt and M w were 9.19 (~ 9.2 cm TL), 10.7 cm TL and 1.37 year−1 for A. coila in the Tetulia River, respectively. These insights are vital for future research and recommending suitable management strategies for A. coila in the Tetulia River and neighboring basins.

This study aimed to determine the length-weight relationship and condition factor of Prussian carp (Carassius gibelio, Bloch, 1782) from the Asi River. Samples were collected by 12-18 mm mesh sized fyke-nets between November and December 2021. Totally 88 specimens have been collected from the Turkish part of Asi River, Hatay, Türkiye. Lengths and weights ranged from 10.2 to 29.8 cm and 19.47 to 408.59 g, respectively. The b-values were calculated as 3.08 and the LWR equation was estimated as W = 0.0138*L3.08. The Fulton’s condition factor (K) and the relative condition factor (Kn) values were calculated as 1.76±0.03 and 1.01±0.01, respectively. This study provides the valuable data on the length-weight relationship and condition factors of C. gibelio from the Asi River. The findings of the present paper revealed that C. gibelio showed an isometric growth and this region is relatively suitable for the growth of this species. Therefore, these data will be a valuable background for further biological studies and local fisheries management strategies.

Faunus ater is a pachychilid gastropod known to inhabit brackish water habi-tats of Western Indo-Pacific countries. This study aimed to analyse the mor-phometric relationships and condition factor of F. ater collected from the Eda-va-Nadayara brackish water lake of Kerala, India. Hydrographic parameters of sampling stations were recorded. A total of 1,522 specimens were collected every month from March 2019 to February 2020. The mean values recorded for total length, shell width, body whorl length, opercular length, opercular width, and total weight were 45.38±13.44 mm, 14.47±3.88 mm, 20.81±5.83 mm, 7.71±3.08 mm, 4.62±1.62 mm, and 6.97±3.72 g, respectively. The length-weight relation was obtained as Log W= -1.005+2.871 Log L. The b value (<3) indicated a negative allometric growth of the organism. Regression analysis of other morphometric measurements also showed a positive correla-tion (P<0.001). The analysis of Fulton’s condition factor indicated a state of well-being of F. ater in this habitat, with condition factors ranging from 5.87 to 6.99 spatially and 5.48 to 7.00 temporally. This study provides the first detailed investigation of morphometric relationships and condition factors in F. ater.

The peacock hind grouper (Cephalopholis argus) is among several highly exploited grouper fishes globally. Categorized as least concern (LC) in the IUCN, biological data on the species is limited, especially in the Aceh region. This research targeted to investigate the biological features of the C. argus fished on the northern coast of Aceh. The fish samples were collected from Pelabuhan Perikanan Samudera (PPS) Lampulo, Kuta Alam District, Banda Aceh, Aceh from June - September 2020. Overall, 30 specimens C. argus were compiled in this study. The total length (TL) varied between 136.0-284.0 mm, while weight (W) ranged between 46.5-460.0 g. In addition, Fulton's condition (K) ranged from 1.45-4.61, and relative weight (Wr) ranged from 81.75-128.53 g. The LWRs analysis revealed a b value of 3.1329 with a correlation coefficient of 0.94, indicating a positive allometric growth pattern. This study provides length-weight relationships (LWR) and condition factors value for the peacock hind grouper that will assist in building a feasible management of the fish.

Full textAbstract:
Abstract An exploration of fish fecundity aimed at estimating the reproductive potential of a stock requires comprehensive and quantitative examinations of the influencing factors. Here, Icelandic summer-spawning herring (Clupea harengus) are used to quantify potential fecundity (FP, number of eggs) and relative fecundity [RFP = FP (body weight − ovary weight)−1] as functions of length (L) and weight (W) in mature prespawning herring. Using a coupled examination of atresia (oocyte degeneration in the ovary) and the maturation stage of oocytes as characterized by size, we show that atresia has no meaningful effect on fecundity estimates if determined near the spawning time. Among prespawning herring, FP is a strong function of L or W (r2 = 0.84 in either case). Fulton's condition factor K (=100WL−3) explains a trivial (1.5%) but significant (p < 0.0001) amount of the residual variation in FP, and appears to have the greatest effect among smaller length classes. RFP is also a function of L (r2 = 0.56), and oocyte diameter explains 36% of the residual variation (p < 0.001). Therefore, stock-specific total egg production in herring can diverge from the assumed proportionality between total egg production and spawning-stock biomass through variations in the length structure of the stock, and to a lesser extent through the condition of prespawning herring.

Abstract The mudskipper is one of the fishes that inhabit mangrove ecosystems. Its growth and distribution is influenced by food sources, tidal action, and environmental factors. The aims of the research were to analyze the growth patterns and condition factors of the mudskipper, Periophthalmus gracilis Eggert, inhabiting mangrove ecosystem rehabilitation areas in Banda Aceh and Aceh Besar, Aceh Province, Indonesia. The research period in these mangrove ecosystems was from August to October 2020. The research was conducted at three sampling stations using the purposive sampling method to determine their location. The mudskippers caught at each station were identified and body length and weight were measured. Physicochemical water parameters were measured directly at the sampling stations to determine the suitability of them for mudskipper growth and occurrence. The mean total lengths (TL) and weights (W) of the mudskipper specimens caught at stations 1, 2, and 3 were 52.0 mm and 6.2 g; 53.5 mm and 6.4 g, and 56.0 mm 6.7 g, respectively. The growth patterns of the mudskippers from the three sampling stations were negative (b < 3), and Fulton’s condition factor (K) exceeded 1. The K value at stations 1, 2, and 3 ranged from 1.28 to 3.62, 1.15 to 3.56, and 1.05 to 3.89, respectively. The relative weights (Wr) at the three stations were 103.8 ± 26.5, 104.3 ± 29.3, and 104.1 ± 28.2, respectively. Wr >100 indicated that there was sufficient food availability, low predator density, and the environment was in equilibrium. Furthermore, physicochemical water parameters at the study stations were suitable and within optimal ranges for the mudskipper. Significant differences in total length were noted among specimens from the three stations (P < 0.05); however, no significant differences in body weight were noted at them (P > 0.05).

Muscle fatigue and exhaustion during dynamic leg exercise in normoxia and hypobaric hypoxia. J. Appl. Physiol. 81(5): 1891–1900, 1996.—Using an exercise device that integrates maximal voluntary static contraction (MVC) of knee extensor muscles with dynamic knee extension, we compared progressive muscle fatigue, i.e., rate of decline in force-generating capacity, in normoxia (758 Torr) and hypobaric hypoxia (464 Torr). Eight healthy men performed exhaustive constant work rate knee extension (21 ± 3 W, 79 ± 2 and 87 ± 2% of 1-leg knee extension O2 peak uptake for normoxia and hypobaria, respectively) from knee angles of 90–150° at a rate of 1 Hz. MVC (90° knee angle) was performed before dynamic exercise and during ≤5-s pauses every 2 min of dynamic exercise. MVC force was 578 ± 29 N in normoxia and 569 ± 29 N in hypobaria before exercise and fell, at exhaustion, to similar levels (265 ± 10 and 284 ± 20 N for normoxia and hypobaria, respectively; P > 0.05) that were higher ( P < 0.01) than peak force of constant work rate knee extension (98 ± 10 N, 18 ± 3% of MVC). Time to exhaustion was 56% shorter for hypobaria than for normoxia (19 ± 5 vs. 43 ± 7 min, respectively; P < 0.01), and rate of right leg MVC fall was nearly twofold greater for hypobaria than for normoxia (mean slope = −22.3 vs. −11.9 N/min, respectively; P < 0.05). With increasing duration of dynamic exercise for normoxia and hypobaria, integrated electromyographic activity during MVC fell progressively with MVC force, implying attenuated maximal muscle excitation. Exhaustion, per se, was postulated to relate more closely to impaired shortening velocity than to failure of force-generating capacity.

e4139111This article features schools and school districts with successful induction programs, all easily replicable. Increasingly, research confirms that teacher and teaching quality are the most powerful predictors of student success. In short, principals ensure higher student achievement by assuring better teaching. To do this, effective administrators have a new teacher induction program available for all newly hired teachers, which then seamlessly becomes part of the lifelong, sustained professional development program for the district or school. What keeps a good teacher are structured, sustained, intensive professional development programs that allow new teachers to observe others, to be observed by others, and to be part of networks or study groups where all teachers share together, grow together, and learn to respect each other’s work.ResumoEste artigo apresenta escolas e distritos escolares com programas bem sucedidos de indução, todos facilmente replicáveis. Cada vez mais, a pesquisa confirma que o professor e a qualidade do ensino são os mais poderosos preditores do sucesso do aluno. Em suma, os diretores garantem maior desempenho dos alunos, garantindo melhor ensino. Para fazer isso, os administradores eficazes têm um novo programa de indução de professores disponível para todos os professores recém-contratados, que então se torna parte do programa de desenvolvimento profissional sustentado ao longo da vida para o distrito ou escola. O que mantém um bom professor são programas estruturados, constantes e intensivos de desenvolvimento profissional que permitem que os novos professores observem outros, sejam observados por outros e façam parte de redes ou grupos de estudo onde todos os professores compartilham juntos, crescem juntos e aprendem a respeitar o trabalho um do outro.Tradução do original WONG, Harry K. “Induction Programs That Keep New Teachers Teaching and Improving”.

Abstract Background Pulmonary arterial hypertension (PAH) is a progressive disease of vascular remodeling characterized by persistent pulmonary arterial pressure elevation, which can lead to right heart failure and premature death. Given the complex pathogenesis and poor prognosis of PAH, the identification and investigation of biomarkers become increasingly critical for advancing further understanding of the disease. Methods PAH-related datasets, GSE49114, GSE180169 and GSE154959, were downloaded from the publicly available GEO database. By performing WGCNA on the GSE49114 dataset, a total of 906 PAH-related key module genes were screened out. By carrying out differential analysis on the GSE180169 dataset, a total of 576 differentially expressed genes were identified. Additionally, the GSE154959 single-cell sequencing dataset was also subjected to differential analysis, leading to the identification of 34 DEGs within endothelial cells. By taking intersection of the above three groups of DEGs, five PAH-related hub genes were screened out, namely Plvap, Cyp4b1, Foxf1, H2-Ab1, and H2-Eb1, among which H2-Ab1 was selected for subsequent experiments. Results A SuHx mouse model was prepared using the SU5416/hypoxia method, and the successful construction of the model was evaluated through Hematoxylin-Eosin staining, hemodynamic detection, fulton index, and Western Blot (WB). The results of WB and qRT-PCR demonstrated a significant upregulation of H2-Ab1 expression in SuHx mice. Consistent with the results of bioinformatics analysis, a time-dependent increase was observed in H2-Ab1 expression in hypoxia-treated mouse pulmonary artery endothelial cells (PAECs). To investigate whether H2-Ab1 affects the development and progression of PAH, we knocked down H2-Ab1 expression in PAECs, and found that its knockdown inhibited the viability, adhesion, migration, and angiogenesis, while concurrently promoted the apoptosis of PAECs. Conclusion H2-Ab1 could regulate the proliferation, apoptosis, adhesion, migration, and angiogenesis of PAECs.

Full textAbstract:
The aim of this study is to determine the length-weight relationship, length-length relationship, and Fulton’s condition factor (K) of Capoeta tinca, which is endemic to Turkey. A total of 52 samples were obtained from Bayat Pond in 2017. The total length (TL) of the samples ranged between 20 and 34 cm. Total weights (W) of they also varied from 85 to 446g. Strong correlations were found between length and weight. In the length-weight relationship equation, a and b was found as 0.0144 and 2.9028, respectively. b value was not statistically different from 3 (t-test, P>0.05). Therefore, this species showed isometric growth in the Bayat Pond. The value of Fulton’s condition factor was 1.0485. Total length - Fork length (FL), Total Length - Standard length (SL) and Fork length - Standard length conversion equations were calculated. There was a high correlation between all length types. In this study, the length-weight relationship, length-length relationship, and Fulton's condition factor values of Capoeta tinca inhabiting Bayat Pond were determined for the first time.

Full textAbstract:
The length-weight relationship data is important basic information that helps to compare species between populations and habitats. In this study, we provide detailed information on the length-weight relationships and condition factors of Lagocephalus guentheri from the Iskenderun Bay, northeastern Mediterranean Sea. A total of 408 (262 Female, 146 Male) specimens were collected on commercial trawlers by local fishermen caught between December 2022 to December 2023 from Iskenderun Bay. The total length range was 11.0-36.9 cm and 11.2-36.7 cm for females and males, respectively. The total weight values of females and males ranged from 20.30-1080.50 g and 20.50-1012.36 g, respectively. The length-weight relationship of L. guentheri was calculated as W = 0.0098 × L3.2145 (R2 = 0.9960) for females, W = 0.009 × L3.2399 (R2 = 0.9963) for males, and W = 0.0095 × L3.2243 (R2 = 0.9962) both sexes. The Fulton’s condition factor was observed as 1.2384 for females, 1.2504 for males, and 1.2335 for both sexes. This study is the most recent reference on length-weight relationships and condition factors for L. guentheri after correction of species identification. It is very important to determine the population parameters of pufferfish species to shed light on the studies to be carried out to restore the ecological balance in the Mediterranean ecosystem. This study will provide basic information that will be useful for fisheries scientists and managers in the Mediterranean Sea.

Full textAbstract:
The aim of this paper is to analyse the morphometric characteristics, length-weight relationship and condition factor of pumpkinseed sunfish (Lepomis gibbosus) from three reservoirs (Modrac, Vidara and Sniježnica) from the area of north-eastern Bosnia and Herzegovina (BiH). The total sample was 61 individuals. The following morphometric parameters were measured: total length, standard length, forked length, head length, mouth width, mouth height, first gill arch length, intestine length and body mass. Length-weight relationship was described by the equation: W=a TLb. Fulton’s condition factor (K) was determined using the equation: K=100 (W/L3). Statistical analysis was performed using the ANOVA to determine differences in morphometric characteristics of individuals between the sites (populations). L. gibbosus from all three populations showed positive allometric growth, and the highest value of condition factor was fish from the reservoir Vidara. In accordance with this result, most of the morphometric characteristics of individuals from the reservoir Vidara were significantly higher compared to individuals from Modrac and Sniježnica reservoirs. This result leads to the conclusion that the L. gibbosus adapted best in Vidara reservoir.

Full textAbstract:
In this study, some basic biological parameters (e.g. sex ratio, condition factor, LWRs and LLRs) of G. artvinicus (Artvin gudgeon) inhabiting Borçka Reservoir and its tributaries from the lower Çoruh River Basin were investigated for the first time. Fish specimens were collected from June 2017 to May 2018 and totally 120 Artvin gudgeon (65 females and 55 males) ranging from 8.1 cm to 13.2 cm in TL were sampled. The sex ratio (F:M) was calculated as 1.18:1.00 in favour of females, but did not deviate from the expected ratio of 1:1 (χ²=0.834, P˃0.05). The total length-weight relationships were determined as W= 0.008TL3.159 (r2=0.971, P˃0.05) for females, as W= 0.012TL2.971 (r2=0.980, P˂0.05) for males and as W= 0.009TL3.088 (r2=0.970, P˃0.05) for all individuals. While the b-values which reflect the body shape were significantly different from the isometric growth indicating positive allometric growth for females and all individuals (Pauly’s t- test, P˂0.05). however, the b value of males did not differ from the isometric growth (b=3) pattern (Pauly’s t- test, P˂0.05). The slopes (b values) were found statistically significant for both sexes (ANCOVA, P 0.9) for each sex and relationship. Mean Fulton's condition factor values were calculated as 1.128±0.011 for females and 1.102±0.008 for males indicating a good growth condition in this habitat. The present study will provide a baseline on some biological parameters of G. artvinicus to provide a guideline for the fisheries management authority and fisheries scientists for further investigations as well as presents the first known reference on the LWRs and LLRs of this species for the FishBase database. Furthermore, the reported results will contribute to the conservation and sustainability of this species in the area.

Full textAbstract:
Some population features (length, weight, LWR, sex ratio and condition factor) were determined for tub gurnard (Chelidonichthys lucernus L. 1758) distributed in the Black Sea coast of Türkiye in the study. The study was conducted between 2018 and 2021 fishing seasons. Fish samples were obtained from the commercial fisheries (demersal trawls and set nets) in the region. A total of 154.788 kg (203 specimens) tub gurnard was captured from all fishing seasons. Mean, maximum and minimum total length were calculated as 38.9±0.99 cm, 73.8 cm and 13.4 cm respectively. Length-weight relationship (LWR) of examined fishes was founded as W=0.0112L2.9425 for all individuals. The “b” parameter was defined as negative allometry growth for females (2.9345), isometry growth for males (2.9535). Fulton’s condition factor were calculated as 0.926±0.009 for all individuals. The observed sex ratio was 1 female: 0.67 male in the examined fishes.

Full textAbstract:
AbstractThis study explores the life‐history parameters of female Merluccius capensis off South Africa (N = 1819) during 2014–2016, including gonadosomatic index (GSI), length‐at‐maturity, length–weight relationships, and condition indices (relative condition [k] and Fulton's condition factor [K]). We detected weak indications of two peaks of spawning within the year, the first in austral autumn from March to May, whereas the other in austral spring around August. GSI was slightly higher in spring and autumn, though still low at all maturity stages (≤7%), though the opposite was true for the actively spawning stage (≥7%) as well as access to less such data during winter‐ and summertime. The length (L) at 50% maturity was around 38 cm (L50), though differences occurred between the two applied staging methods, histology and visual (macroscopic) classification, when L approached infinity. The latter method presented underestimated length at maturity values at the 75 and 95 percentiles (48 and 60 cm) compared to the corresponding percentiles given by histology (50 and 65 cm). There were trivial across‐method differences in L50. However, we found a clear reduction in L50 in view of published information in prior years when this estimate was 48 (1985), 42 (2008), 53 (2011), and 24.8 (2015) cm. Overall, L explained 90% of the variation in whole body weight (W). As the bootstrapped, grand mean growth coefficient was b = 2.98, indicating a slight allometric growth function, there were no significant variations between years, though an isometric growth existed for 2016 with b = 3.0, whereas for 2014 and 2015 this b was 2.98 and 2.93, respectively. In terms of demography, females <60 cm generally showed isometric growth (b = 3) as opposed to allometric growth (b = 2.95) at >60 cm. The relative condition index (k = 1) exhibited higher values than Fulton's K, which was 0.80. Overall, the maternal stock of M. capensis along the south coast seems to be in good condition and likely spawns throughout the year, but we found that the macroscopic data tend to give biased maturity ogives.
