Full textAbstract:
In the years 1801–6 a series of lawsuits were filed in various London courts involving many of England's top piano manufacturers. Swirling around a lawsuit by the Anglo-Irish piano inventor William Southwell against John and James Shudi Broadwood for infringement of his seminal 1794 patent were actions involving the opportunistic James Longman, his brother John Longman, his partner Francis Fane Broderip, and his successors, Muzio Clementi & Co., as well as George Astor, the firm of Culliford, Rolfe & Barrow, August Leukfeld, and George Wilkinson. In this article the authors reconstruct the issues and outcomes of these legal actions and their ramifications for William Southwell, who emerges as a victim of his own inventive success, and the nascent English piano industry. We draw upon the original court papers, as well as a family memoir of Southwell, the parish record of his burial in 1825, the 1802 partnership agreement of Southwell & Co., contemporary newspaper notices, prison records, apprenticeship records, the wills of several of the makers, and newly located original drawings and descriptions for patents by Southwell (1794) and his son, William junior (1837), held at The National Archives, Kew.

Cytogenetic characterization was carried out on 12 accessions from Aster squamatus (Spreng.) Hieron., Pterocaulon polystachyum DC, and Solidago microglossa DC by studying their meiotic behavior and pollen viability. These species are from the Asteraceae family, native to Rio Grande do Sul State, Brazil, and are important for medicinal use. Young inflorescences with four accessions of each species were collected, fixed in ethanol-acetic acid (3:1), and conserved in ethanol 70% until use. The method used was that of squashing the anthers and coloring with acetic orcein 2%. Meiosis was regular in all accessions, presenting chromosomal associations preferentially bivalent, where n=10 was found for Aster squamatus and n=9 for Pterocaulon polystachyum, and Solidago microglossa. The studied accessions presented a Meiotic Index (MI) that varied from 65% to 87% in Aster squamatus, 85% to 92% in Pterocaulon polystachyum, and 64% to 92% in Solidago microglossa, indicating meiotic stability, although irregularities appeared during the cellular division. The pollen viability estimative was high in all studied accessions. These results indicate that the studied species can be included in future studies of genetic breeding.

Full textAbstract:
Stokes aster is a herbaceous perennial native to the southeastern United States. Stokesia is a monotypic genus belonging to the tribe Vernonieae Cass. (family Asteraceae Dumont). The level of genetic diversity within the genus is unknown. The goal of this study was to determine the level of genetic diversity and relatedness among cultivars of stokes aster. The genetic relatedness among 10 cultivars of stokes aster, one accession of Vernonia crinita Raf. (syn. V. arkansana DC.), and one accession of Rudbeckia fulgida Ait. var. sullivantii (Beadle et Boynton) Cronq. `Goldsturm' was estimated using 74 randomly amplified polymorphic DNA (RAPD) primers. Similarity indices suggest that cultivars of stokes aster are very closely related, with values for all pairwise comparisons of cultivars of stokes aster ranging from 0.92 to 0.68. One cultivar, `Omega Skyrocket', had markedly lower similarity indices from the other cultivars, ranging from 0.72 to 0.68. Similarity indices between stokes aster and Vernonia and between stokes aster and Rudbeckia were 0.44 and 0.50, respectively.

Full textAbstract:
Segregation analysis of two different F2 families of stokes aster created by hybridizing two blue-flowered cultivars [`Peaches Pick' (PE) and `Omega Skyrocket' (OSR)] with the yellow-flowered cultivar `Mary Gregory' (MG) gave disparate results. The F2 progeny of PE × MG segregated in the expected 3:1 (blue:yellow) ratio. In contrast, all 782 progeny from the MG × OSR F2 family were blue-flowered. Flow cytometric analysis of the parents and F1 hybrids was conducted to determine if ploidy differences existed among the parents, as such differences could account for aberrant segregation behavior in the MG × OSR F2 family. Peak ratios suggested that MG and PE were diploid, OSR was tetraploid, and F1 hybrids of MG × OSR were triploid. Chromosome counts from root tip squashes confirmed that MG and PE were diploid (2n= 2x= 14), OSR was tetraploid (2n= 4x= 28), and F1 hybrid progeny of MG × OSR were triploid (2n= 3x= 21). Karyotype analysis also confirmed these results. We propose that the lack of recovery of yellow-flowered progeny in the MG × OSR F2 family is due to differences in parental chromosome number. These results document the first report of polyploidy in stokes aster, and suggest the absence of a triploid block in this species.

Full textAbstract:
Parental Involvement in their children's schooling has long been recognized as a critical component of good education. This study aims to find out the relationship between socioeconomic status, interpersonal communication, and school climate with parental involvement in early childhood education. Using survey and correlational research design, data collection was carried out through accumulation techniques with tests and questionnaires. The data analysis technique used statistical analysis and multiple regressions. The findings in the socio-economic context of parents show that the measure of power is an indicator in the very high category with a total score of 5, while the measures of wealth, honour and knowledge are included in the high category with a total score of 4 in relation to parental involvement. The form of interpersonal communication, the openness of parents in responding happily to information / news received from schools about children is a finding of a significant relationship with parental involvement in early childhood education. The school climate describes the responsibility for their respective duties and roles, work support provided, and interpersonal communication relationships, parents at home and teachers at school.

Full textAbstract:
Narrowly lanceolate leaves occur frequently in the genus Aster. It was often employed as a distinguishing character in the taxonomy of this genus. The origin of this particular leaf shape, however, has never been investigated using comparative methods. In this study, we reconstructed a comprehensive phylogeny that includes most species of Aster with narrowly lanceolate leaf. We then gathered data on riparian habitats and the presence or absence of narrowly lanceolate leaves, and investigated the evolutionary association between them in a phylogenetic context. Our analysis indicated that the species with narrowly lanceolate leaves are nested in unrelated lineages of the genus Aster, implying that they originated independently several times. Using Pagel’s comparative method of discrete data, we demonstrated a significant correlation between riparian habitats and narrowly lanceolate leaves. We further inferred the sequence of transition of the two characters. This analysis indicated that the sequence of evolution of riparian habitat and narrowly lanceolate leaf form was usually uncertain, but some positive results showed that the occurrence of riparian habitats may not precede the evolution of narrowly lanceolate leaf form. This study provided new insights into the adaptive evolution in a mega-diverse family. In addition, Aster tonglingensis, an unexpected new species with narrowly lanceolate leaves, was discovered and established based on the evidence from morphology, micromorphology and molecular phylogeny.

Palynological studies on ten species of angiosperms family namely Hibiscus rosa- sinensis L.(Malvaceae), Lilium candidum L. (Liliaceae), Petunia axillaris (Lam.) B.S.P.(Solanaceae) and seven species from family asteraceae namely Artemisia indica Willd., Aster ageratoides Kitam., Calendula offcinalis L., Cerpis japonica L. (Benth.), Sonchus asper (L.) Hill, Tagetus patula L., and Taraxicum officinale F.H.Wigg. was carried out. Result obtained from this investigation showed that pollen shape is spheroidal in Artemisia indica, Aster ageratoides, Calendula offcinalis, Hibiscus rosa- sinensis and P. axillaris; elliptical in L. candidum, hexagonal in S. asper and pentagonal in T. officinale; tricolpater in C.japonica. Pollen aperture is porate in all except in L.candidum where it is elliptic. Pollen wall is echinate in H.rosa-sinensis, A.ageratoides, T. patula; spinulate in P. axillaries, T. officinale, S. asper, C. japonica, C. officinalis and T. officinale and smooth in L. candidum. The general appearance of the pollen grain is circular in P. axillaries but longer than wide in L.candidum. The circular, echinate, large and triporate pollens seem to be primitive ones and spharoidal, hexaporate features have been regarded as comparatively advanced ones. Polyporate pollens are considered to be secondarily derived. The nature of the pollen grain in these species could be evolutionary significance. The similarities in structure of the pollen grain showed the inter- species relationships among the species and that’s why put in same family while the differences in structures showed reasons for them to exist as distinct species. Only one species namely L.candidum from monocot family (Liliaceae) included in this study. Int. J. Appl. Sci. Biotechnol. Vol 5(3): 361-365

Abstract: Payroll is an acceptance in return from the employer to the employee for a job or service that has been done and is expressed or valued in the form of money determined on the basis of an agreement or legislation and is paid on the basis of an employment agreement between the employer and the employee including benefits, both for the employees themselves and for the family. This research takes place at PT. Astro Niaga Jaya. The payroll process at PT. Astro Niaga Jaya is still conventional. Salary calculations are based on different details that hinder the performance process of the human resources department. Errors in calculating salaries can be fatal because it will affect the preparation of financial statements. Therefore, it is necessary to have an employee payroll information system so that the human resources department is not wrong in collecting employee payroll data. The purpose of this paper is to design employee attendance and payroll information systems at PT. Astro Niaga Jaya using Waterfall method in order to produce information that is fast, precise and accurate. The Waterfall method is often used in designing an information system.

We sequenced and analyzed the complete chloroplast genome of Aster tataricus (family Asteraceae), a Chinese herb used medicinally to relieve coughs and reduce sputum. The A. tataricus chloroplast genome was 152,992 bp in size, and harbored a pair of inverted repeat regions (IRa and IRb, each 24,850 bp) divided into a large single-copy (LSC, 84,698 bp) and a small single-copy (SSC, 18,250 bp) region. Our annotation revealed that the A. tataricus chloroplast genome contained 115 genes, including 81 protein-coding genes, 4 ribosomal RNA genes, and 30 transfer RNA genes. In addition, 70 simple sequence repeats (SSRs) were detected in the A. tataricus chloroplast genome, including mononucleotides (36), dinucleotides (1), trinucleotides (23), tetranucleotides (1), pentanucleotides (8), and hexanucleotides (1). Comparative chloroplast genome analysis of three Aster species indicated that a higher similarity was preserved in the IR regions than in the LSC and SSC regions, and that the differences in the degree of preservation were slighter between A. tataricus and A. altaicus than between A. tataricus and A. spathulifolius. Phylogenetic analysis revealed that A. tataricus was more closely related to A. altaicus than to A. spathulifolius. Our findings offer valuable information for future research on Aster species identification and selective breeding.

Asteraceae family shows a great diversity in Cuba and presents threatened taxons in high number. Pinar del Río has 19 threatened species belonging to this family and three of them are characteristic of a sandy (quartzitic) soil at the Reserva Florística Manejada San Ubaldo-Sabanalamar (Floristic Reserve San Ubaldo-Sabanalamar). The arbuscular mycorrhizal status and colonization rate in Aster grisebachii, Erigeron bellidiastroides, Erigeron cuneifolius, Pectis juniperinaand Sachsia polycephala (Asteraceae) from this Reserve was determined in October 2009 and April 2010, during hydrologic rainy and dry period, respectively. All species were mycotrophic in both periods with a high percentage of colonization rates, between 66 and 100% in rainy period and between 84 and 100% in dry period. Vesicles, arbuscules, spores, hyphal and arbuscular coils of arbuscular mycorrhizae were observed. Paris -type andArum -type morphologies (both) were observed indistinctly in all the species, and Intermediate type was observed only in Aster grisebachii andErigeron bellidiastroides, which could be a hint that these species are colonized by more than one fungal species, and therefore enhancing the relevance of fungal identity as a considerable character in the morphology association. Also, septate hyphae and microsclerotium of dark septate endophytes were identifyed inside the roots of all the species.

Full textAbstract:
AbstractHuntington Library manuscript HM904 is a verse miscellany compiled by Constance Aston Fowler, daughter of Lord Aston, in 1630s Staffordshire. Constance operated as a kind of literary agent, soliciting, exchanging, and circulating poems, as well as preserving them in her book. Many of these poems are by or about family and friends, but they also indicate her connections with far-reaching networks of manuscript transmission. In particular, the volume contains Catholic devotional verses in an unusual and somewhat archaic hand (Hand B) that also appears in another Catholic miscellany from 1650s Warwickshire; and secular verses that may be by the Catholic love poet William Habington, or may be hybrid compositions that imitate or adapt his work. Both these ingredients have much to say about the complex compilation processes of manuscript verse miscellanies, and about the cultural participation of women and Catholics in seventeenth-century England.

Abstract Aims The aim of this study was to compare the efficiency of three defense mechanisms (ionic balance, osmotic adjustment and counteracting oxidative stress) under low, moderate and high soil salinity in two related species of contrasting tolerance to salinity: the halophyte Aster tripolium and the glycophyte Aster alpinus, and to elucidate their phytohormone-mediated regulation. Methods The phytohormonal profiling was performed to asses correlations between the pool of plant growth regulators and parameters depicting ionic homeostasis, osmotic adjustment and antioxidant system. Results Defense mechanisms in both species were based on accumulation/activity of distinct compounds (Na+ and K+ ions, antioxidants), but differences among species concerned particularly soluble carbohydrates and betaines. The halophyte accumulated mannitol, uronic acids and sucrose, while the glycophyte mostly glucose and proline-betaine. The halophyte responses also correlated with changes in the content of plant growth promoting PGRs, as well as jasmonates and benzoic acid. The glycophyte responses corresponded with changes in content of abscisic acid and ethylene precursor, as well as salicylic acid. Conclusions We provided evidence that benzoic acid rather than salicylic acid is involved in salt tolerance in the halophyte and elevated SA content may enhance vulnerability to salt excess. An important element of tolerance trait is also JA-GA network that influences the intensity of defense responses. This study uncovers new aspects of internal phytohormonal regulation of plant reaction to soil salinity and enables further insight into extremophyte biology.

The first molecular analysis of samples collected in southern Backa (Serbia) confirmed the presence of aster yellows (16SrI) and stolbur phytoplasmas (16SrXII) in insects belonging to the family Cicadellidae, as well as in carrot plants where the insects were collected. A correct identification of the phytoplasmas and their vectors is essential to arrange effective control strategies to prevent diseases associated with phytoplasmas from spreading to carrots and other vegetable crops. In order to enhance knowledge about insect vectors of aster yellows and stolbur phytoplasmas in Serbia, Cicadellidae and Cixiidae (Homoptera Auchenorrhyncha), the most common vectors of these phytoplasmas, were monitored in southern Backa during 2008. Adults leaf- and planthoppers were collected and identified at species level using standard entomological methods, and tested for phytoplasma presence by means of PCR/RFLP. A total of 13 insect species of Cicadellidae were identified, as follows: a) three species of the subfamily Agallinae: Anaceratagallia ribauti (Ossiannilsson), Anaceratagallia venosa (Fourcroy), and Anaceratagallia laevis (Ribaut); b) seven species of the subfamily Deltocephalinae: Psammotettix confinis (Dahlbom), Psammotettix striatus (Linnaues) Psammottettix alienus (Dahlbom), Macrosteles sexnotatus (Fall?n), Ophiola decumana (Kontkanen), Errastunus ocellaris Fall?n, and Scaphoideus titanus Ball; c) three species of the subfamily Typhlocibinae: Eupteryx atropunctata (Goeze), Eupteryx mellissae Curtis, Zyginidia pullula (Boheman). Female specimens of the genus Euscelis (Deltocephalinae) were also collected, as well as one species of Reptalus quinquecostatus (Dufour) of the family Cixiidae. Stolbur phytoplasmas were detected in A. laevis, A. ribauti, A. venosa, P. striatus, P. confinis and P. alienus. The species: A. laevis, O. decumana, and P. confinis were AY-infected (subgroup 16SrI-A), while subgroup 16SrI-C was found only in one specimen of P. confinis. Since some aster yellows- and stolbur-infected species of the genera Psammotettix and Anaceratagallia (especially P. confinis and A. laevis) were regularly and commonly found in the infected carrot fields during the whole vegetative period, they could play a significant role in transmitting and spreading these pathogens in natural environment.

Full textAbstract:
The Xenopus protein Maskin has been previously identified and characterized in the context of its role in translational control during oocyte maturation. Maskin belongs to the TACC protein family. In other systems, members of this family have been shown to localize to centrosomes during mitosis and play a role in microtubule stabilization. Here we have examined the putative role of Maskin in spindle assembly and centrosome aster formation in the Xenopus egg extract system. Depletion and reconstitution experiments indicate that Maskin plays an essential role for microtubule assembly during M-phase. We show that Maskin interacts with XMAP215 and Eg2, the Xenopus Aurora A kinase in vitro and in the egg extract. We propose that Maskin and XMAP215 cooperate to oppose the destabilizing activity of XKCM1 therefore promoting microtubule growth from the centrosome and contributing to the determination of microtubule steady-state length. Further more, we show that Maskin localization and function is regulated by Eg2 phosphorylation.

Full textAbstract:
We have prepared antibodies specific for HSET, the human homologue of the KAR3 family of minus end-directed motors. Immuno-EM with these antibodies indicates that HSET frequently localizes between microtubules within the mammalian metaphase spindle consistent with a microtubule cross-linking function. Microinjection experiments show that HSET activity is essential for meiotic spindle organization in murine oocytes and taxol-induced aster assembly in cultured cells. However, inhibition of HSET did not affect mitotic spindle architecture or function in cultured cells, indicating that centrosomes mask the role of HSET during mitosis. We also show that (acentrosomal) microtubule asters fail to assemble in vitro without HSET activity, but simultaneous inhibition of HSET and Eg5, a plus end-directed motor, redresses the balance of forces acting on microtubules and restores aster organization. In vivo, centrosomes fail to separate and monopolar spindles assemble without Eg5 activity. Simultaneous inhibition of HSET and Eg5 restores centrosome separation and, in some cases, bipolar spindle formation. Thus, through microtubule cross-linking and oppositely oriented motor activity, HSET and Eg5 participate in spindle assembly and promote spindle bipolarity, although the activity of HSET is not essential for spindle assembly and function in cultured cells because of centrosomes.

Aqueous and methanolic extracts of three plants at four different concentration viz. at 50, 100, 150 and 200 mg/ml were tested on clinical bacteria using the disc diffusion method. In vitro antibacterial activity was screened by using Nutrient Agar (NA). The qualitative phytochemical analysis depicted the presence of terpenoids, saponins, alkaloids, flavonoids, carotenes and glycosides in the plants. Results showed broad spectrum antimicrobial activity against the Gram-negative and Gram-positive bacteria. The methanol extract inhibited the growth of more bacteria compared to the aqueous extract. Results from in vitro study revealed that the antimicrobial activity might have been influenced by the solubility of active compound(s) in extracting solvent. Methanol extracts were relatively more effective than aqueous extract. Out of three invasive plants studied Parthenium hysterophorus seemed more effective, for inhibiting the growth of bacterial strains with maximum zone of inhibition (24.85 mm diam.), shown against Enterococcus faecalis at a concentration of 200 mg/ml. The demonstration of activity against all these organisms had shown that all three alien invasive species; Ageratum haustonianum, Mikania micrantha and Parthenium hysterophorus can be used to produce raw materials/substances for further development of diverse antibiotics with broad spectrum of activity.ECOPRINT 23: 1-12, 2016

Full textAbstract:
Urban areas have very complex spatial structures. These spatial structures are primarily composed of a complex network of built environments, which evolve rapidly as the cities expand to meet the growing population’s demand and economic development. Therefore, studying the impact of spatial structures on urban heat patterns is extremely important for sustainable urban planning and growth. We investigated the relationship between surface temperature obtained by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER, at 90 m spatial resolution) and different urban components based on high-resolution QuickBird satellite imagery classification. We further investigated the relationships between ASTER-derived surface temperature and building footprint and land use information acquired by the New York City (NYC) Department of City Planning. The ASTER image reveals fine-scale urban heat patterns in the NYC metropolitan region. The impervious-medium and dark surfaces, along with bright covers, generate higher surface temperatures. Even with highly reflective urban surfaces, the presence of impervious materials leads to an increased surface temperature. At the same time, trees and shadows cast by buildings effectively reduce urban heat; on the contrary, grassland does not reduce or amplify urban heat. The data aggregated to the census tract reveals high-temperature hotspots in Queens, Brooklyn, and the Bronx region of NYC. These clusters are associated with industrial and manufacturing areas and multi-family walk-up buildings as dominant land use. The census tracts with more trees and higher building height variability showed cooling effects, consistent with shadows cast by high-rise buildings and trees. The results of this study can be valuable for urban heat island modeling on the impact of shadow generated by building heights variability and trees on small-scale surface temperature patterns since recent image reveals similar hotspot locations. This study further helps identify the risk areas to protect public health.

<i>Ceropegia bulbosa</i> Roxb. is a narrow endemic, tuberous twiner of Asclepiadaceae family. It is medicinally important: tubers are nutritive and edible, leaves are digestive and a cure for dysentery and diarrhea. Exploitation for its tubers and poor regeneration of this species has shrunk its distribution. In order to know its present status, we report here the results of its appraisal in Rajasthan, using remote sensing and ground truthing in the past five years (2009–14). A base map of <i>C. bulbosa</i> was prepared using Geographical Information System (GIS), open source software Quantum GIS, SAGA. The Landsat Enhanced Thematic Mapper (ETM) +Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), Global Digital Elevation Model (GDEM) Satellite Data were used in this study. ASTER and GDEM Data was clipped with district boundary and provided color range to get elevation information. A digital elevation model of Rajasthan physiography was developed from ASTER GDEM of 30-m resolution. GIS layers of Area of occurrences for <i>C. bulbosa</i> plant and elevation were created. This map along with topographic sheets of 1:50000 were used for field traversing and ground truthing as per GPS location inferred from map. Its geographic distribution was assessed using MaxEnt distribution modelling algorithm that employed 12 presence locality data, 19 bioclimatic variables, and elevation data. Results of this modelling predicted occurrence of <i>C. bulbosa</i> in the districts of Sirohi, Jalore, Barmer, Pali, Ajmer, Jhalawar, Dungarpur, Banswara, Baran, Kota, Bundi and Chittorgarh. Ground validation in these districts revealed its presence only at four places in three districts confirming its rarity. Analysis of dominance at their sites of occurrence revealed their poor populations and sub dominant status (RIV = 20–32) and very low density (2–12 plants per tenth ha).

Full textAbstract:
Multiple asters (MAST)/Orbit is a member of a new family of nonmotor microtubule-associated proteins that has been previously shown to be required for the organization of the mitotic spindle. Here we provide evidence that MAST/Orbit is required for functional kinetochore attachment, chromosome congression, and the maintenance of spindle bipolarity. In vivo analysis of Drosophila mast mutant embryos undergoing early mitotic divisions revealed that chromosomes are unable to reach a stable metaphase alignment and that bipolar spindles collapse as centrosomes move progressively closer toward the cell center and eventually organize into a monopolar configuration. Similarly, soon after depletion of MAST/Orbit in Drosophila S2 cells by double-stranded RNA interference, cells are unable to form a metaphase plate and instead assemble monopolar spindles with chromosomes localized close to the center of the aster. In these cells, kinetochores either fail to achieve end-on attachment or are associated with short microtubules. Remarkably, when microtubule dynamics is suppressed in MAST-depleted cells, chromosomes localize at the periphery of the monopolar aster associated with the plus ends of well-defined microtubule bundles. Furthermore, in these cells, dynein and ZW10 accumulate at kinetochores and fail to transfer to microtubules. However, loss of MAST/Orbit does not affect the kinetochore localization of D-CLIP-190. Together, these results strongly support the conclusion that MAST/Orbit is required for microtubules to form functional attachments to kinetochores and to maintain spindle bipolarity.

Aster spathulifolius Maxim. is belongs to the Asteraceae family, which is distributed only in Korea and Japan. The species is traditionally a medicinal plant and is economically valuable in the ornamental field. On the other hand, the Aster genus, among the Asteraceae family, lacks genomic resources and its molecular functions. Therefore, in our study the high-throughput RNA-sequencing transcriptome data of A. spathulifolius were obtained to identify the molecular functions and its characterization. The de novo assembly produced 98660 uniqueness with an N50 value of 1126bp. Total unigenes were procure to analyze the functional annotation against databases like non-redundant protein, Pfam, Uniprot, KEGG and Gene ontology. The overall percentage of functional annotation to the nr database (43.71%), uniprotein database (49.97%), Pfam (39.94%), KEGG (42.3%) and to GO (30.34%) were observed. Besides, 377 unigenes were found to be involved in the terpenoids pathway and 666 unigenes were actively engaged in other secondary metabolites synthesis, given that 261 unigenes were within phenylpropanoid pathway and 81 unigenes to flavonoid pathway. A further prediction of stress resistance (9,513) unigenes and transcriptional factor (3,027) unigenes in 53 types were vastly regulated in abiotic stress respectively in salt, heat, MAPK and hormone signal transduction pathway. This study discovered 29,692 SSR markers that assist the genotyping approaches and the genetic diversity perspectives. In addition, eight Asteraceae species as in-group together with one out-group were used to construct the phylogenetic relationship by employing their plastid genome and single-copy orthologs genes. Among 50 plastid protein-coding regions, A. spathulifolius is been closely related to A. annua and by 118 single copy orthologs genes, O. taihangensis is more neighboring species to A. spathulifolius. Apart from this, A. spathulifolius and O. taihangensis, genera have recently diverged from other species. Overall, this research gains new insights into transcriptome data by revealing and exposing the secondary metabolite compounds for drug development, the stress-related genes for producing resilient crops and an ortholog gene of A. spathulifolius for the robustness of phylogeny reconstruction among Asteraceae genera.

L.E.A. Rowson was always known as Tim to his family, friends and colleagues alike. He was a veterinary surgeon who made important contributions to research in reproductive physiology in farm animals and its application to animal breeding. In particular, he was a pioneer of artificial insemination (AI) and embryo transfer, which have become two of the most important technologies for livestock improvement in modern times.He was appointed Director of the first AI centre for cattle breeding in Britain, established at Cambridge in 1942, and played a leading role in the application and rapid growth of this technology. In 1952 he contributed to the development of successful methods for the freezing and long-term storage of bull semen at very low temperatures. This had far-reaching consequences for the future of AI and cattle breeding worldwide.For thirty years he also worked at the Animal Research Station in Cambridge on methods for embryo transfer in sheep and cattle and their use in research and breeding. This culminated in the 1970s with the development of effective methods for collection and transfer of cattle embryos by non-surgical means. The birth of the first calf after transfer of a deepfrozen embryo in 1973 was another landmark, and these advances led quite quickly to the commercial application of embryo transfer in cattle breeding.Tim Rowson is generally regarded as the founder of embryo transfer in farm animals, but important contributions were made by many collaborators. He always considered that he was privileged during his early years to have worked with Dr John (later Sir John) Hammond, F.R.S., who maintained that the function of applied science was to synthesize the detailed knowledge gained from fundamental research into a constructive whole so that it could be used for a specific purpose. Tim was a true disciple of this philosophy and always tried to relate a fundamental approach to a practical outcome.

A civil paternity investigation involving the parents of the deceased alleged father in order to establish a family relationship is presented. On the basis of the 23 autosomal short tandem repeat (aSTR) genotyping results, conclusive proof of paternity was not achieved, as the probability of paternity (W) was calculated to 0.99988. Additional genetic data of 17 classical and non-classical human leukocyte alleles (HLA) typing by next-generation sequencing (NGS) at a high-resolution level supported the hypothesis of grandpaternity over the hypothesis of coincidental paternal obligate allele (POA) sharing (total WaSTR&HLA = 0.9999998). The present study demonstrates the utility of 17 HLA genetic markers-typing in the solution of deficiency cases of disputed parentage.

New taxa are represented by one species recently described and few other are probably undescribed. The most species-rich family in the area was Synaphobranchidae (11 species), followed by Congridae (9), Nettastomatidae (5), Nemichthyidae (3), Serrivomeridae (2), Colocongridae (1), Cyematidae (1), and Eurypharyngidae (1). Regarding the vertical species distribution, a gradual transition of species was observed, without any clear break along the slope.

New collections made by the French research vessel Thalassa and the Brazilian Astro Garoupa on the Brazilian continental slope, between 11° and 23° S revealed a great diversity of deep-sea gadiforms obtained between 200 and 2270 m. Of the 34 species collected, 13 (38%) are being reported for the first time in the western South Atlantic and one may represent a new species. The most species-rich family in the area is Macrouridae (25 species), followed by Moridae (4), Phycidae (2), Merlucciidae (2), and Bregmacerotidae (1). Most of the species collected is also found in the Gulf of Mexico and Caribbean and have their known ranges of distribution extended into the tropical waters of central Brazil. Four species typically occur in temperate waters and were found only in the southernmost stations. A summary comparison of the bathymetric distributions of each species on the slope is provided.

In this autobiographical account, I first describe my family, then childhood and education in India. During 1953–55, I worked in the new field of radio astronomy at the Division of Radiophysics of the Commonwealth Scientific and Industrial Research Organisation in Australia. During 1956–57, I worked at the Radio Astronomy Station of Harvard University at Fort Davis, Texas, where I made observations of solar radio bursts at decimeter wavelengths. I then joined Stanford University as a graduate student in 1957. I contributed to the successful operation of the Stanford Cross Antenna and then used it for studying microwave radio emission from the Sun. I was awarded the Ph.D. degree by Stanford University in 1960 and was then appointed as an Assistant Professor for three years. With an urge to contribute to evolving scientific endeavors in India, I joined the Tata Institute of Fundamental Research (TIFR) at Mumbai, India, in April 1963. In my stay of more than three decades at TIFR, I conceived of, and guided, construction of two of the world's largest radio telescopes, namely the Ooty Radio Telescope and the Giant Metrewave Radio Telescope. These instruments have led to several outstanding contributions and discoveries in the areas of radio galaxies, quasars, pulsars, and cosmology.

The European Union stepped into the year 2002 with mixedfeelings. On the one hand, the anthraxcrisis and the war in Afghanistan remembered of the terrorist attacks of 11 September 2001. On the other hand, the introduction of the euro notes and coins created a EU-wide feeling of euphoria. In the following twelve months, EU activity was mainly dominated by the impeding eastern enlargement. Moreover, in 2002, the institutional foundations were laid ofwhat will turn out to be one of the mostfundamental transformations ofthe European construction in EU history. As most of these activities will be settled in the years to come, asfor 2002, especially the starting point - the introduction of the euro coins and notes -and the end point- the decision ofthe Copenhagen European Council to welcome Cyprus, Estonza, Hungary, Latvia, Lithuania, Malta, Poland, Slovenia, the Czech Republic and the Slovak Republic in 2004 into the European family - will remain printed in the European memory.

<p><strong>Abstract.</strong> Deep learning has been used successfully in computer vision problems, e.g. image classification, target detection and many more. We use deep learning in conjunction with ArcGIS to implement a model with advanced convolutional neural networks (CNN) for lithological mapping in the Mount Isa region (Australia). The area is ideal for spectral remote sensing as there is only sparse vegetation and besides freely available Sentinel-2 and ASTER data, several geophysical datasets are available from exploration campaigns. By fusing the data and thus covering a wide spectral range as well as capturing geophysical properties of rocks, we aim at improving classification accuracies and support geological mapping. We also evaluate the performance of the sensors on their own compared to a joint use as the Sentinel-2 satellites are relatively new and as of now there exist only few studies for geological applications. We developed an end-to-end deep learning model using Keras and Tensorflow that consists of several convolutional, pooling and deconvolutional layers. Our model was inspired by the family of U-Net architectures, where low-level feature maps (encoders) are concatenated with high-level ones (decoders), which enables precise localization. This type of network architecture was especially designed to effectively solve pixel-wise classification problems, which is appropriate for lithological classification. We spatially resampled and fused the multi-sensor remote sensing data with different bands and geophysical data into image cubes as input for our model. Pre-processing was done in ArcGIS and the final, fine-tuned model was imported into a toolbox to be used on further scenes directly in the GIS environment. The tool classifies each pixel of the multiband imagery into different types of rocks according to a defined probability threshold. Results highlight the power of using Sentinel-2 in conjunction with ASTER data with accuracies of 75% in comparison to only 70% and 73% for ASTER or Sentinel-2 data alone. These results are similar but examining the different classes shows that there are significant improvements for classes such as dolerite or carbonate sediments that are not that widely distributed in the area. Adding geophysical datasets reduced accuracies to 60%, probably due to an order of magnitude difference in spatial resolution. In comparison, Random Forest (RF) and Support Vector Machines (SVMs) that were trained on the same data only achieve accuracies of 46 % and 36 % respectively. Most insecurity is due to labelling errors and labels with mixed lithologies. However, results show that the U-Netmodel is a powerful alternative to other classifiers for medium-resolution multispectral data.</p>

Full textAbstract:
Symptoms of phyllody of flowers and general plant yellowing indicating possible phytoplasma infection were observed in diseased plants of hairy willow-weed (Epilobium hirsutum L., family Onagraceae) growing in a meadow at Harku Village near Tallin, Estonia. DNA was extracted from diseased E. hirsutum using a Genomic DNA Purification Kit (Fermentas AB, Vilnius, Lithuania) and used as a template in nested polymerase chain reaction (PCR). Ribosomal (r) DNA was initially amplified in PCR primed by phytoplasma universal primer pair P1/P7 (4) and reamplified in PCR primed by nested primer pair 16SF2n/16SR2 (F2n/R2) (1) as previously described (2). Products of 1.8 kbp and 1.2 kbp were obtained in PCR primed P1/P7 and F2n/R2, respectively, from all four symptomatic plants examined. These data indicated that the diseased E. hirsutum plants were infected by a phytoplasma, termed epilobium phyllody (EpPh) phytoplasma. The 16S rDNA amplified in PCR primed by nested primer pair F2n/R2 was subjected to restriction fragment length polymorphism (RFLP) analysis using restriction endonucleases AluI, MseI, HpaI, HpaII, HhaI, RsaI, HinfI, and HaeIII (Fermentas AB). On the basis of the collective RFLP profiles, EpPh phytoplasma was classified in group 16SrI (aster yellows phytoplasma group), subgroup B (aster yellows phytoplasma subgroup), according to the phytoplasma classification scheme of Lee et al. (3). The 1.8-kbp rDNA product of P1/P7-primed PCR, which included 16S rDNA, 16S-23S intergenic spacer region, and the 5′ -end of 23S rDNA, was cloned in Escherichia coli using the TOPO TA Cloning Kit (Invitrogen, Carlsbad, Ca) according to manufacturer's instructions and sequenced. The sequence was deposited in the GenBank database as Accession No. AY101386. This nucleotide sequence shared 99.8% sequence similarity with a comparable rDNA sequence (GenBank Accession No. AF322644) of aster yellows phytoplasma AY1, a known subgroup 16SrI-B strain. The EpPh phytoplasma sequence was highly similar (99.9%) to operons rrnA (GenBank Accession No. AY102274) and rrnB (GenBank Accession No. AY102273) from Valeriana yellows (ValY) phytoplasma infecting Valeriana officinalis plants in Lithuania. ValY phytoplasma was found to exhibit rRNA interoperon sequence heterogeneity (D. Valiunas, unpublished data). To our knowledge, this is the first report to reveal E. hirsutum as a host of phytoplasma and to demonstrate the occurrence of a plant pathogenic mollicute in the northern Baltic region.

Full textAbstract:
Abstract Michael Haneke’s Time of the Wolf (Le temps du loup, 2003) depicts a grim vision of the world in the aftermath of an unnamed catastrophe. Haneke turns the genre of dystopia into an experimental terrain where he can test the limits of the cinematic medium in the sense of “negating cinema in order to let reality speak for itself” (Nagib 2016, 147). An existential parable, Time of the Wolf envisions a sombre post-millenium age. It is a sharp analysis of what remains of man and society when the frame of civilization collapses. It scrutinizes the functioning mechanisms of the individual, the family and the social community in times of civilization undone. A harsh experiment towards a negative dialectics of the image, the film’s exceptionally austere cinematic language confronts the spectator with the aesthetics of the “unwatchable” (Baer et al., 2019) and “cinematic unpleasure” (Aston 2010). The paper explores the ways in which Haneke’s “intermedial realism” (Rowe 2017) also manifests in this film through photo-filmic images and painterly compositions, perceptions of stillness and motion, and cultural remnants of the past, giving way to affective sensations of intermediality.

Full textAbstract:
The Gulf of St. Lawrence Aster, Symphyotrichum laurentianum, is a member of the family Asteraceae and is listed as “threatened” by COSEWIC (Committee on the Status of Endangered Wildlife in Canada). This rare and vulnerable halophyte grows in only a few locations in New Brunswick, Prince Edward Island, and the Magdalen Islands, Quebec. As an annual, S. laurentianum relies exclusively on its seeds to survive to the next generation. The goal of this study was to estimate the quantity of viable S. laurentianum seeds in the persistent and transient seed banks at selected sites in Prince Edward Island. Overall, the number of seeds in the transient and persistent seed banks is low. The greatest concentration of seeds was found near the surface of the soil. In addition, only a small proportion of those seeds tested positive for viability based on Tetrazolium staining. Of the seeds in the persistent and transient seed banks combined, 53% were viable whereas only 2% of the seeds in the persistent seed bank were viable. Population surveys were also completed at the five known sites (both extinct and extant) in Prince Edward Island National Park. All sites showed signs of decline based on population estimates dating back to 1993. The Covehead Pond site showed the greatest decline: from 250-300 individuals in 1993 to only 10 individuals in 2002. The population at Dune Slack also showed a dramatic decrease from approximately 65 000 in 1999, to 2 200 individuals in 2002. Monitoring of this plant and the development of a management plan for the species are critical to its survival.

Full textAbstract:
The article presents a taxonomic analysis for the decorative plants collection in the Polar Experimental Station of the VIR branch. The collection fund of floral and ornamental plants of the VIR Polar Experimental Station currently contains 208 species, 90 cultural forms and varieties from 53 families. The collection of annual crops is represented by 21 genera, 22 species, 69 varieties from 14 families. Perennial herbaceous decorative plants on the Polar OS VIR have 101 genera, 140 species from 40 families. The collection of decorative shrubs at the Polar Experimental Station consists of 20 genera, 47 species from 11 families. From the collection of herbaceous floral and decorative crops, the plants from the Asteraceae family are most represented. The Asteraceae occupies a dominant position in the collection of annuals in terms of the number of species and varieties (8 genera, 9 species, 24 varieties). The families Solanaceae and Violaceae each have one species, but the number of cultivars cultivated at the station (9 and 18, respectively) makes it possible to distinguish them from the general composition of the collection of annuals. Among the decorative herbaceous perennials, the largest number of species (≥10) are the families: aster (18 genera, 24 species), buttercup (7 genera, 12 species), carnation (5 genera, 10 species), rosaceae (7 genera, 10 species). The family Rosaceae in the collection of decorative shrub plants is predominant in number and has 10 genera and 29 species. All decorative plants of the VIR Polar Experimental Station nursery of different life forms are introduced. The main work is aimed at attracting modern varieties, new species, and intraspecific forms to the collection. The analysis of the taxonomic structure of plant species, varieties and forms allows us to identify and recommend the most resistant to extreme growing conditions plants that have high decorative qualities, taking into account modern trends in urban floristics.

Full textAbstract:
Phytoplasmas are intracellular bacterial plant pathogens that cause devastating diseases in crops and ornamental plants by the secretion of effector proteins. One of these effector proteins, termed SECRETED ASTER YELLOWS WITCHES’ BROOM PROTEIN 54 (SAP54), leads to the degradation of a specific subset of floral homeotic proteins of the MIKC-type MADS-domain family via the ubiquitin-proteasome pathway. In consequence, the developing flowers show the homeotic transformation of floral organs into vegetative leaf-like structures. The molecular mechanism of SAP54 action involves binding to the keratin-like domain of MIKC-type proteins and to some RAD23 proteins, which translocate ubiquitylated substrates to the proteasome. The structural requirements and specificity of SAP54 function are poorly understood, however. Here, we report, based on biophysical and molecular biological analyses, that SAP54 folds into an α-helical structure. Insertion of helix-breaking mutations disrupts correct folding of SAP54 and compromises SAP54 binding to its target proteins and, concomitantly, its ability to evoke disease phenotypes in vivo. Interestingly, dynamic light scattering data together with electrophoretic mobility shift assays suggest that SAP54 preferentially binds to multimeric complexes of MIKC-type proteins rather than to dimers or monomers of these proteins. Together with data from literature, this finding suggests that MIKC-type proteins and SAP54 constitute multimeric α-helical coiled coils. Our investigations clarify the structure-function relationship of an important phytoplasma effector protein and may thus ultimately help to develop treatments against some devastating plant diseases.

Full textAbstract:
We describe the phenotypic and molecular characterization of twinstar (tsr), an essential gene in Drosophila melanogaster. Two P-element induced alleles of tsr (tsr1 and tsr2) result in late larval or pupal lethality. Cytological examination of actively dividing tissues in these mutants reveals defects in cytokinesis in both mitotic (larval neuroblast) and meiotic (larval testis) cells. In addition, mutant spermatocytes show defects in aster migration and separation during prophase/prometaphase of both meiotic divisions. We have cloned the gene affected by these mutations and shown that it codes for a 17-kD protein in the cofilin/ADF family of small actin severing proteins. A cDNA for this gene has previously been described by Edwards et al. (1994). Northern analysis shows that the tsr gene is expressed throughout development, and that the tsr1 and tsr2 alleles are hypomorphs that accumulate decreased levels of tsr mRNA. These findings prompted us to examine actin behavior during male meiosis to visualize the effects of decreased twinstar protein activity on actin dynamics in vivo. Strikingly, both mutants exhibit abnormal accumulations of F-actin. Large actin aggregates are seen in association with centrosomes in mature primary spermatocytes. Later, during ana/telophase of both meiotic divisions, aberrantly large and misshaped structures appear at the site of contractile ring formation and fail to disassemble at the end of telophase, in contrast with wild-type. We discuss these results in terms of possible roles of the actin-based cytoskeleton in centrosome movement and in cytokinesis.

A survey was conducted in the Macedonia region of Greece to determine the reservoir hosts of Tomato spotted wilt virus (TSWV) in three tobacco fields and in a greenhouse complex in which lettuce and the ornamentals chrysanthemum, gerbera, aster, and anemone were grown. Assays for TSWV infection were made by enzyme-linked immunosorbent assay on 6,172 plant samples, 3,909 from tobacco fields and 2,263 from the greenhouse complex, comprising plants of 208 species in 137 genera of 42 families. Plants of 86 species out of 63 genera of 27 families were infected of which 39 species are newly reported hosts of TSWV. An infection index was developed to evaluate the relative potential of each weed species as a virus source in both systems. Seventeen species in the tobacco fields and nine in the greenhouses had an infection index higher than one. Most species with infected plants were found in the Compositae family. Plants of some species occurring both in tobacco fields and in greenhouses were infected at only one of these sites. Frankliniella occidentalis was the common thrips species on weeds and crops in the greenhouses, while Thrips tabaci was the only vector on tobacco plants and weeds in the tobacco fields. This observation strongly suggests that the occurrence of species with infected plants and their number have to be attributed to the vector species prevailing in the greenhouse complex or tobacco fields, supporting the conclusion that TSWV is spread in two different epidemiological processes in Greece.

Full textAbstract:
The family Thorectidae includes 23 valid genera and 130 species, characterized by the presence of laminated fibres and diplodal choanocytye chambers. Currently the genus Thorecta comprises approximately 20 valid species, distributed mainly in the Indo-Pacific. We describe here a new species of Thorecta that is the only valid species of the genus described in the Atlantic Ocean so far. Samples were collected by trawling on board of the RV ‘Astro Garoupa’ in Potiguar Basin, on the northern coast of Rio Grande do Norte State, north-eastern Brazil. Thorecta atlantica sp. nov. is greyish-brown to dark brownish-grey and presents a distinctive globular or clavulate shape, with 1–2 large apical oscules that open to deep atria. It was found between 61 and 160 m depth. A literature survey suggests that many species referred to Thorecta should be relocated to different genera due to absence of diagnostic characters, and that the genus Thorecta should group only 11 species: T. carteri, T. marginalis, T. prima, T. lata, T. farlovi, T. meandrina, T. polygona, T. reticulata, T. tuberculata, T. vasiformis and T. atlantica sp. nov. The tortuous history of the genus is an example of the damage that poorly-described species can cause to classification. Detailed descriptions of fresh material, well illustrated by photographs and including as many characters as possible, are essential tools for the clarification of the systematics of Thorecta in the future.

The challenge of implementing character education has an impact on the development of children's character. This study aims to describe the form of parenting using tueak serembeak in early character development and education in the Rejang tribe. This qualitative research uses a case study method with two male respondents. Data was collected by documentation, interviews, observations, and field notes and analysed using the Miles and Huberman stages. The theoretical study as the basis of research shows that tueak serembeak can form twelve characters in early childhood, responsibility, courage to take decisions, sharing, caring, survival, tenacity, cooperation, hard work, never give up, keep the spirit, dare to accept challenges, and be patient in dealing with problems. However, the findings in the field show that there are only four characters that appear, being responsible, sharing, caring and patient in dealing with problems. Other characters that appear not based on the teachings of tueak serembeakare independent, creative, and friendly characters. This happens because of the influence of external intervention, education in Air Raman Village, which has developed, advanced technology and open community life. A suggestion for further research, is experimental research based on tueak serembeak teachings that can explain more clearly the influence of this teaching on other aspects of child development.

"FEATURES OF THE COMPOSITION OF FLAVONOIDS IN THE CROWNED SAW-WORT (SERRATULA CORONATA L.S.L.) SIBERIA AND THE FAR EAST OF RUSSIA." chemistry of plant raw material, no. 2 (June 10, 2020): 171–79. http://dx.doi.org/10.14258/jcprm.2020026663.
Full textAbstract:
One of the common plants in Siberia and the Far East of Russia, but little studied, is the crowned saw-wort (Serratula coronata L.s.l.) of the aster family (Asteraceae). The value of this plant is determined by its high content of phytoecdysteroids and flavonoids. From the aerial part (leaves, stems) of S. coronata L.s.l., growing in Siberia (Altai Region), by liquid extraction methods (70% ethanol) and preparative column chromatography on silica gel in the gradient elution mode with a mixture of solvents (carbon tetrachloride and ethyl alcohol), 2 flavonoids were isolated: quercetin-4'-O-β-D-glucopyranoside, luteolin-4'-O-β-D-glucopyranoside. Identification of the isolated compounds was carried out by UV-, NMR-13C-, 1H, 13C-HMBC-spectroscopy and electrospray mass spectrometry. The reverse-phase high-performance liquid chromatography (RP-HPLC) method was the first to investigate the qualitative composition and quantitative content of individual flavonoids in S. coronata L.s.l. plants growing in Altai and in the Primorsky region of the Russian Federation. The composition of flavonoid glycosides and the distribution of their aglycones in Siberian and Far Eastern plants differ and this can be considered a chemotaxonomic trait of the species S. coronata L.s.l. The spectrophotometry method was used to determine the sum of flavonoids in the aerial organs of crowned saw-wort growing in Altai and Primorsky region. The content of flavonoids in the leaves of the plant (6.7–8.3%) exceeds their content in the stems (0.5–0.9%). Crowned saw-wort sickle is a potential source of biologically active compounds of this class.

Full textAbstract:
SummaryAmbatovaky Special Reserve was created in 1956 and is the largest lowland rainforest reserve in Madagascar, comprising more than half of the total area of this habitat represented in the country's protected area system, yet there are no measures in place actively to protect it, due to its remoteness and a lack of funds. This study in February-March 1990, part of the first faunal survey to be undertaken in the reserve, found seven threatened, five near-threatened and two other localized bird species. In itself this would make the reserve an important site for conservation. However, three of the finds are of particular note: Ambatovaky is one of only two known sites for the Red-tailed Newtonia Newtonia fanovanae which was rediscovered in 1989; a dead Madagascar Serpent-eagle Eutriorchis astur was found - the first specimen since 1930 of one of the world's rarest raptors; and the White-breasted Mesite Mesitornis variegata was discovered in rainforest where Brown Mesite M. unicolor was also present, this being the only known case of sympatry within the endemic Mesitornithidae family. Shifting cultivation threatens the habitat of all these species and an integrated plan for conservation and sustainable development for the local people is urgently needed.La Réserve Spéciale d'Ambatovaky a été crée en 1956 et représente la plus grande réserve de forêt pluviale à basse altitude de Madagascar. Elle couvre plus de la moitié de la superficie totale de cet habitat, intégrée au système de zones protégées du pays. Pourtant, à cause de l'isolement géographique et du manque de ressources financières, aucune mesure de protection active n'a pu être encore mise en place. Cette étude accom-plie en février-mars 1990, et faisant partie de la première recherche menée sur la faune de cette réserve, a permis de découvrir sept espéces d'oiseaux menacées, cinq especes presque menacees et deux espèces locales. En soi, cela suffirait pour dormer à cette réserve le statut de site important pour la conservation. Cependant, trois de ces decouvertes méritent une attention particulière: Ambatovaky est l'un des deux seuls sites connus abritant la Newtonia fanovanae qui a été redécouverte en 1989; un aigle-autour de Madagascar, l'Eutriorchis astur a été trouvé mort - le premier spécimen depuis 1930 de l'un des rapaces les plus rares au monde; et le Mesitornis variegata, découvert dans la forêt pluviale où le Mesitornis unicolor éiait également présent, ceci représentant le seul cas connu de sympatrie à l'intérieur de la famille endémique des Mesitornithidae. L'exten-sion des cultures agricoles menace l'habitat de toutes ces espèces, et il est urgent d'établir un plan de conservation et de développement pour la population locale compatible avec l a conservation des ressources naturelles.

Full textAbstract:
Maskin is the Xenopus homolog of the transforming acidic coiled coil (TACC)-family of microtubule and centrosome-interacting proteins. Members of this family share a ∼200 amino acid coiled coil motif at their C-termini, but have only limited homology outside of this domain. In all species examined thus far, perturbations of TACC proteins lead to disruptions of cell cycle progression and/or embryonic lethality. In Drosophila, Caenorhabditis elegans, and humans, these disruptions have been attributed to mitotic spindle assembly defects, and the TACC proteins in these organisms are thought to function as structural components of the spindle. In contrast, cell division failure in early Xenopus embryo blastomeres has been attributed to a role of maskin in regulating the translation of, among others, cyclin B1 mRNA. In this study, we show that maskin, like other TACC proteins, plays a direct role in mitotic spindle assembly in Xenopus egg extracts and that this role is independent of cyclin B. Maskin immunodepletion and add-back experiments demonstrate that maskin, or a maskin-associated activity, is required for two distinct steps during spindle assembly in Xenopus egg extracts that can be distinguished by their response to “rescue” experiments. Defects in the “early” step, manifested by greatly reduced aster size during early time points in maskin-depleted extracts, can be rescued by readdition of purified full-length maskin. Moreover, defects in this step can also be rescued by addition of only the TACC-domain of maskin. In contrast, defects in the “late” step during spindle assembly, manifested by abnormal spindles at later time points, cannot be rescued by readdition of maskin. We show that maskin interacts with a number of proteins in egg extracts, including XMAP215, a known modulator of microtubule dynamics, and CPEB, a protein that is involved in translational regulation of important cell cycle regulators. Maskin depletion from egg extracts results in compromised microtubule asters and spindles and the mislocalization of XMAP215, but CPEB localization is unaffected. Together, these data suggest that in addition to its previously reported role as a translational regulator, maskin is also important for mitotic spindle assembly.

Full textAbstract:
Temporal lobe epilepsy is a widespread chronic disorder that manifests as spontaneous seizures and is often characterized by refractoriness to drug treatment. Temporal lobe epilepsy can be caused by a primary brain injury; therefore, the prevention of epileptogenesis after a primary event is considered one of the best treatment options. However, a preventive treatment for epilepsy still does not exist. Neuroinflammation is directly involved in epileptogenesis and neurodegeneration, leading to the epileptic condition and cognitive decline. In the present study, we aimed to clarify the effect of treatment with a recombinant form of the Interleukin-1 receptor antagonist (anakinra) on epileptogenesis and behavioral impairments in rats using the lithium–pilocarpine model. We found that anakinra administration during the latent phase of the model significantly suppressed the duration and frequency of spontaneous recurrent seizures in the chronic phase. Moreover, anakinra administration prevented some behavioral impairments, including motor hyperactivity and disturbances in social interactions, during both the latent and chronic periods. Histological analysis revealed that anakinra administration decreased neuronal loss in the CA1 and CA3 areas of the hippocampus but did not prevent astro- and microgliosis. The treatment increased the expression level of the solute carrier family 1 member 2 gene (Slc1a2, encoding excitatory amino acid transporter 2 (EAAT2)) in the hippocampus, potentially leading to a neuroprotective effect. However, the increased gene expression of proinflammatory cytokine genes (Interleukin-1β (Il1b) and tumor necrosis factor α (Tnfa)) and astroglial marker genes (glial fibrillary acidic protein (Gfap) and inositol 1,4,5-trisphosphate receptor type 2 (Itpr2)) in experimental rats was not affected by anakinra treatment. Thus, our data demonstrate that the administration of anakinra during epileptogenesis has some beneficial disease-modifying effects.
