Full textAbstract:
The Duration of Arctic Invasions (DAI) is known to be connected with various climatological indexes. This paper presents the results of a study of DAI changes in various sectors of the Northern Hemisphere from 1899 to 2017. To this end, we used the classification of circulating mechanisms of the Northern Hemisphere by B.L. Dzerdzeevsky.The basic attention was paid to the study of the trend component of the temporal variability of the duration of Arctic invasions; to the assessment of long-period cyclic fluctuations of the DAI; and to the forecasting the duration of Arctic invasions over the next decade in the Northern Hemisphere sectors.To analyze the components of the change in the duration of Arctic invasions and its forecast, we used: a description of the initial data using a linear trend, approximation of time series by the Savitsky-Golay method, spectral analysis and spectral-time analysis, as well as the component-harmonic method.We found a significant increase in the duration of Arctic invasions in the Pacific and Atlantic sectors and its significant decline in the European and American sectors. In deviations from the trend, a powerful quasi-fifty-year component for five sectors is clearly manifested; whereas in the European sector the deviation is rather weak and quasi-thirty-year fluctuations dominate here. What is more, quasi-20-year fluctuations in the variability of DAI were revealed, we predict DAI estimates for the next 10 years by combining the trend and two quasi-cyclic fluctuations. According to our forecast an increase in the duration of Arctic invasions will occur from 2022 in the European sector. In the Atlantic sector, DAI growth will begin in 2019 and continue until 2023, and then DAI will fall. In other sectors, there will be a decrease in the duration of Arctic invasions starting from 2016. The decrease in American sector starts only from 2022.

We have previously reported a soybean plant introduction, PI 437153A, which was ineffectively nodulated (definition of G. Vest, D. F. Weber, and C. Sloger, Agronomy 16:353–390, 1973) by Bradyrhizobium japonicum strain UMR (University of Minnesota Rhizobium) 161. In this study, we further characterize this nodulation system by (i) examining the nodulation of 21 B. japonicum strains, representing 15 serogroups, with PI 437153A, (ii) ascertaining the inheritance of the ineffective nodulation, and (iii) characterizing the symbiosis both morphologically and physiologically. Only USDA 126 (serogroup 125) and UMR 161 failed to produce effective nodules with PI 437153A. Segregation among F2 and F3 plants from a cross between cv. Lambert and PI 437153A was consistent with control of this trait by a single, dominant gene. In reciprocal grafts between cv. Lambert and PI 437153A, ineffective nodulation was determined by the root genotype, and was independent of plant growth temperature and inoculant concentration. The nodule dry weight of UMR 161-inoculated plants of PI 437153A plants was approximately 10-fold less than that of comparable plants inoculated with USDA 110; nodule soluble protein levels were also significantly reduced. Nitrogenase activity and leghemoglobin could not be detected in the ineffectively nodulated phenotype, but 1 to 6 days after inoculation (DAI) phenylalanine ammonialyase RNA level was higher in the ineffectively nodulated phenotype than in the effectively nodulated one. Microscopic examination of effective and ineffective nodules 20 and 35 DAI revealed major morphological differences. Ineffective nodules contained large, deteriorating regions near apparently infected plant cells at 35 DAI, and schlerenchyma cells that were stained red, suggestive of lignin deposition. These changes could be the result of incompatibility between host and Bradyrhizobium, though the lack of chalcone synthase expression and the appearance of infected cells within the ineffective nodules suggest that some later steps in the infection process do occur.

Riemannian manifolds with nonzero Killing spinors are Einstein manifolds. Kröncke proved that all complete Riemannian manifolds with imaginary Killing spinors are (linearly) strictly stable in [Stable and unstable Einstein warped products, preprint (2015), arXiv:1507.01782v1 ]. In this paper, we obtain a new proof for this stability result by using a Bochner-type formula in [X. Dai, X. Wang and G. Wei, On the stability of Riemannian manifold with parallel spinors, Invent. Math. 161(1) (2005) 151–176; M. Wang, Preserving parallel spinors under metric deformations, Indiana Univ. Math. J. 40 (1991) 815–844]. Moreover, existence of real Killing spinors is closely related to the Sasaki–Einstein structure. A regular Sasaki–Einstein manifold is essentially the total space of a certain principal [Formula: see text]-bundle over a Kähler–Einstein manifold. We prove that if the base space is a product of two Kähler–Einstein manifolds then the regular Sasaki–Einstein manifold is unstable. This provides us many new examples of unstable manifolds with real Killing spinors.

Geopolymer concrete is established to have brilliant designing properties with a decreased carbon impression. Geopolymer with fibers has gained prevalence in recent years for use in concrete, for the most part, inferable from their low cost and outstanding individuality. In this examination, Fiber-Reinforced Geopolymer Concrete (FRGPC) is utilized as a binder with the impacts of the intrinsic sulfate solution in Gypseous Soil. GPC blend is included with alkaline activators, for example, NaOH and KOH with molarities [M. Z. N. Khan, Y. Hao, H. Hao and F. U. A. Shaikh, Cem. Concr. Compos.85 (2018) 133; P. Sukontasukkul, P.

The Gypseous Soil is taken with the percentage of G13,G25,G54, to assess the effects, compressive strength, ductility, collapsibility potential, and coefficient of penetrability tests were performed with a soaked and unsoaked solution. These outcomes are validated with the assistance of an Artificial Neural Network (ANN) optimization algorithm. The validation results played out that ideal precision and high strength of the activated solution. At long last, the simulated outcomes give better execution compared with existing papers.

Abstract The Toyoshiki-dai housing complex, constructed in 1960s, is located in one of the commuter towns in a metropolitan area of Japan. Those who moved to this area as youngsters are now aged over 75 and many live a solitary life; making social support vital to prevent social frailty. The municipalities and universities have been hosting interventions, e.g. club activities, to make social connection but the effects remain unclear. In this study, the relationship between activity participation and the size of social support was explored to develop an effective method to increase social connections. A cross-sectional study was conducted in October 2018 and 200 questionnaires were distributed at a lunch event at the housing complex. The participants were solitary and independent seniors over the age of 70 (M:F=14.4:67.5). The frequency of going out to participate in club activity, see friends, and the geriatric social support scale were used for analysis. As a result, compared to seniors who went out to see their friends, the size of social support was smaller in groups that remained isolated (N = 161, odds ratio = 0.26, 95% CI=0.11-0.60). On the contrary, seniors who joined club activities had similar size of social support despite the frequency of participation. Clubs in Japan are often closed groups with limited membership, which may have restricted the addition of new social connection. Future intervention researches should focus on modifying the membership system of clubs and opening of a public space where seniors can casually access and talk to acquaintances.

Full textAbstract:
The purpose of this study was to determine the mechanisms of dopamine regulation of phosphate uptake in opossum kidney (OK) cells, a model of proximal renal tubules. Dopamine stimulated cAMP generation and inhibited radiolabeled phosphate uptake into OK cell monolayers by 14.4 +/- 1.8%. The effect of dopamine was transient, as phosphate uptake returned toward control level by 3 h despite the continued presence of dopamine. Pretreatment with pertussis toxin increased dopamine inhibition of phosphate uptake to 25 +/- 3%, increased the duration of the dopamine effect to at least 3 h, and enhanced cAMP generation. In an OK cell clone that overexpressed cAMP phosphodiesterase, dopamine did not inhibit phosphate uptake, but pharmacologic inhibition of protein kinase A activation did not prevent dopamine inhibition of phosphate uptake. A DA1 receptor agonist inhibited phosphate uptake more potently than dopamine (29.5 +/- 1.1%) or a DA2 receptor agonist (7.9 +/- 2%). However, both DA1 and DA2 receptor antagonists completely blocked dopamine inhibition of phosphate uptake. DA1, but not the DA2, antagonists blocked dopamine-stimulated cAMP generation. Treatment with alpha-adrenergic receptor antagonists potentiated dopamine inhibition of phosphate uptake to the same extent as pertussis toxin and was not additive with pertussis toxin. It is concluded that dopamine inhibits phosphate uptake through DA1 and DA2 receptor stimulation by cAMP-dependent and -independent pathways and activates a pertussis toxin-sensitive counter-regulatory pathway that attenuates this response through alpha-adrenergic receptor stimulation.

O biochar é produto da degradação térmica de materiais orgânicos na presença limitada de oxigênio (pirólise), e sua adição aos solos influencia nos atributos químicos, físicos e em comunidades microbianas. A produção do biochar pode ser uma alternativa para o reaproveitamento de resíduos da agro-indústria. O objetivo do presente estudo foi avaliar o impacto de resíduos gerados na indústria de biodiesel (puro e transformado em biochar) nas atividades enzimáticas, atributos químicos e microbiológicos do solo arenoso. O experimento foi distribuído em esquema fatorial 5 x 5, sendo o primeiro fator constituído por: apenas o solo (controle); resíduo de Graviola (RG), resíduo de Pinha (RP) biochar do resíduo de graviola (BG) e biochar do resíduo de pinha (BP) e o segundo fator, cinco tempos de incubação 0, 30, 60, 90 e 120 dias após incubação (DAI), com 4 repetições. Foram avaliados, atributos químicos do solo, carbono da biomassa microbiana (CBM) e atividades enzimáticas (uréase, fosfatase acida e alcalina). Solos tratados com RG apresentaram um incremento na urease aos 120 DAI (3,8 vezes maior que o controle). A aplicação de BG ao solo no tempo 0 incrementou os teores de fosfatase ácida, fosfatase alcalina, uréase e CBM (1,1; 1,2; 1,4 e 1,1 vezes) e o pH (1,2 vezes). Solos que receberam BP apresentaram incrementos no pH, CBM aos 120 DAI, fosfatase alcalina aos 120 DAI e uréase aos 60 DAI. Ambos os resíduos e biochar de graviola contribuíram para a qualidade bioquímica, microbiológica e química do Neossolo regolítico arenoso. Impact of biochar Residues from the biodiesel industry on the attributes of a sandy soil A B S T R A C TThe current call for the use of renewable energy generates a quantity of waste that, if not handled correctly, can cause environmental damage. For this reason, research that aims to reuse these residues to be applied in agriculture has been carried out, such as those that transform such wastes into biochar. Biochar is a product of pyrolysis and its addition to soils has an influence on chemistry, physics and microbial communities. The objective of the present study was to evaluate the impact of seed cake (pure and transformed into biochar) on the enzymatic activities, chemical and microbiological attributes of the sandy soil. The experiment was distributed in a 5 x 5 factorial scheme, the first factor being: only the soil (control); Graviola residue (RG), Pine cone residue (RP) Biochar of graviola residue (BG) and Biochar of pine cone residue (BP) and the second factor, five incubation times 0, 30, 60, 90 and 120 days after incubation (DAI). Soil chemical attributes, microbial biomass carbon (CBM) and enzymatic activities (urea, acid and alkaline phosphatase) were evaluated. RG treated soils showed an increase in urease at 120 DAI (3.8 times greater than the control). The application of BG to the soil at time 0 increased the levels of acid phosphatase, alkaline phosphatase, urea and CBM (1.1; 1.2; 1.4 and 1.1 times) and pH (1.2 times). Soils that received BP showed increases in pH, CBM at 120 DAI, alkaline phosphatase at 120 DAI and urea at 60 DAI. Soursop biochar contributed to the biochemical and microbiological quality of the soil, demonstrating its greater potential for agricultural use compared to the others.Keywords: biochar, soil chemistry, enzyme activity, incubation

Tai people, formally known as of Dai nationality in China, number 1.1 million. One of the greatest concentrated region of Dai people in China is the reaches of the Red River, called the Yuan Jiang River. Here their ethnic culture is particularly to be found. The Dai people of the Red River number about 150,000 which is 13% of the total Dai population of China. Furthermore about half of those 150,000 live in Xin Ping and Yuan Jiang counties, on the upper reaches of the river. Traditionally, the Dai people of the upper Red River were called Huayao Dai, or "Flower Waist" Dai, because of the long and colourful waistband which is an ethnic symbol of the women. The Huayao Dai comprise various sub-ethnic groups, such as Dai Ya, Dai Ka and Dai Saai in Xin Ping county, and Dai Ya, Dai Zhong, Dai Zhang and Dai De in Yuan Jiang county. The Huayao Dai have various cultural features which distinguish them from other Dai. 1) Ethnic fmery, such as the women's waistband, which has a varied cultural significance. 2) Adobe houses, quite different from those of the Dai people outside this region. 3) Festivals, many of which are shared with the Han, but have their own features. The Flower Fair Festival is Huayao Dai. 4) An Animist religion, similar to that of other Dai, but with certain distinguishing features.

Full textAbstract:
Background: Many patients with schizophrenia have low medication adherence. There is, however, no objective assessment scale that can be used by nurses or caregiver specialists. The Nursing Assessment of Medication Acceptance (NAMA) was developed to assess patients’ medication adherence. The aim of this study was to examine the validity and reliability of the NAMA in patients with schizophrenia. Methods: A total of 121 Japanese patients with schizophrenia were enrolled. All patients underwent evaluation using the NAMA and the Drug Attitude Inventory (DAI-10). Reliability was investigated using a test-retest method and a parallel-test method. To determine the test-retest reliability of the NAMA, we tested 101 schizophrenia patients twice, with the second assessment 2–4 weeks after the date of the first assessment. For validity verification, standard-related validity and the degree of concordance with the DAI-10 scores were measured. Results: The Cronbach’s alpha value of the NAMA in schizophrenia was 0.88. The test-retest correlation coefficients were all between 0.53–0.74. The total scores and all subscores for the NAMA were significantly correlated, and the NAMA total scores were significantly correlated with the DAI-10 total scores. Conclusions: The NAMA shows good reliability and validity in measuring medication adherence in schizophrenia.

Most potato (Solanum tuberosum L.) is produced as a non-irrigated crop in the southeastern United States. This practice makes potato yields dependent on rainfall pattern and amount. An irrigation scheduling method based on a water balance and class A pan evaporation data (Ep) was evaluated in Spring 1996 on a fine sandy loam soil with `LaSoda' potatoes. Planting date was 9 Apr. and standard production practices were followed. The model was (12.7 DAH + 191) * 0.5 ASW = D(DAH-1) + [Ep (0.12 + 0.023 DAH - 0.00019 DAH*DAH) - R(DAH) - I(DAH)], where DAH is days after hilling (DAH = 0 on 14 May), ASW is available soil water (0.13 mm/mm), D is soil water deficit (mm), R is rainfall (mm) and I is irrigation (mm). Root depth expanded at a rate of 13 mm/day to a maximum depth of 305 mm. Root depth at hilling was 191 mm. Controlled levels of water application ranging between 0% and 161% of the model rate were created with drip tapes. The model scheduled irrigations on 35, 39, 43 and 49 DAH. On 85 DAH, potatoes were harvested and graded. Irrigation influenced total yield, marketable yield, and combined US #1 grades (P < 0.01; R2 > 0.85). Mean marketable yields were 19, 28, and 21 t/ha for the 0%, 100%, and 160% irrigation rates, respectively. These results suggest that supplementing rainfall with irrigation and controlling the amount of water applied by adjusting irrigation to actual weather conditions could increase potato yields. Excessive water, as well as limiting water, reduced potato yields.

IntroductionBetween 25–50% of psychiatric patients are non-compliant with their pharmacological treatment. When differences between compliant and non-compliant patients were analyzed, differences were found in relation to their beliefs and feelings about medication. The Drug Attitude Inventory (DAI) was created to measure attitudes towards medication in adults. It predicted adherence in schizophrenia and depression studies.ObjectiveDetermine if psychotherapeutic and psychoeducational activities – during a partial hospitalization at the Psychiatric Day Hospital – can improve aspects related to feelings and thoughts about medication.MethodWe gathered retrospectively a sample of 151 patients hospitalized at the Psychiatric Day Hospital, from September 2013 to June 2015. Their thoughts and feelings about medication were measured with the DAI before and after the hospitalization. From the sample of 151 patients, 94 completed both tests, excluding who did not have the final DAI score. Differences between initial and final scores were statistically analyzed with the Wilcoxon test for paired samples.ResultsOf the 94 patients who completed the study, 52 showed an improvement in their DAI score, whereas the remaining 27 showed an equal or decreased final DAI compared to initial evaluation. The difference was statistically significant (P ≤ 0.05).ConclusionIt seems that psychoeducational activities related to medication are important in order to reconsider or modify feelings and thoughts about treatment. Information on medication provided to psychiatric patients (to those who need psychopharmacological treatment), carried out in a group context, which facilitates an open and sincere communication, can be a useful strategy to improve compliance with treatment.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Plant growth of two woody ornamentals, 'Green Luster' Japanese holly and 'Fashion' azalea, and monthly medium solution electrical conductivity (EC) were determined. Growth index [GI = (height + width at widest point + width perpendicular to widest point)/3] response to fertilizer treatment was species specific. Nutricote 20-7-10 (type 360) produced the largest GIs for holly, while GIs for azalea were not affected 420 days after initiation (DAI) of the test. Plants potted in April had greater GIs than those potted in June for the two plant species 420 DAI, regardless of fertilizer type. Osmocote 18-6-12 and 17-7-12 controlled release fertilizers had the greatest medium solution ECs from 90 to 180 DAI.

Os tratamentos corresponderam às épocas de avaliação (21, 35, 49, 63, 77, 91, 105, 119, 133, 147 e 161 dias após a emergência – DAE) e foram arranjados em delineamento inteiramente casualizado com quatro repetições. Plantas de U. arrecta apresentaram baixo acúmulo (menor que 7% dos valores máximos acumulados aos 161 DAE) de matéria seca (5,1 g MS por planta) e de macronutrientes (57,7 mg N por planta; 8,9 mg P por planta; 167,8 mg K por planta; 21,3 mg Ca por planta; 14,7 mg Mg por planta; e 9,2 mg S por planta) até 49 DAE. Esses acúmulos se intensificaram principalmente após 91 DAE; a taxa diária de acúmulo foi crescente até 130 DAE (MS e S), 137 DAE (N), 125 DAE (P), 119 DAE (K), 144 DAE (Ca) e 128 DAE (Mg), quando houve acúmulo de 87,7 g MS por planta; 918,0 mg N por planta; 105,8 mg P por planta; 1.643,9 mg K por planta; 390,4 mg Ca por planta; 200,0 mg Mg por planta; e 103,5 mg S por planta. K e N foram os macronutrientes com os maiores teores e, consequentemente, mais requeridos e acumulados em maior quantidade nos tecidos vegetais de plantas de U. arrecta.

OBJECTIVE: A study was made of the brain lesions in 120 random victims of fatal road traffic accidents to determine the frequency and topographic distribution of diffuse axonal damage (DAI) in relation to the midline brain structures. METHOD: The identification of axons was carried out with a mouse antibody anti-neurofilament proteins 70-, 160-, and 210-kD. RESULTS: DAI was identified in 96 (80%) brains and classified as Grade 1 in 21.9%, as Grade 2 in 51%, and as Grade 3 in 27.1% of the patients. In spite of the diffuse distribution that is characteristic of DAI, damage occurred preferentially in the interhemispheric formations (corpus callosum and fornix) and rostral portion of the brainstem, usually to one side of the midline. CONCLUSION: From a mechanical point of view, the interhemispheric formations and the rostral portion of the brainstem act as fixating structures for the cerebral hemispheres during rotational acceleration of the head. It is known that the motion of the cerebral hemispheres is delayed at the points of fixation, where greater stress would be produced, particularly on the side subjected to greater displacement. The frequent involvement by DAI of deep, center-medial brain structures, usually to one side of the midline, supports the mechanism proposed above.

Purpose of the study—to develop a new dosage form—rectal suppositories with vitamin D3 and at the preclinical stage to analyze its clinical and immunological efficacy compared to 5-aminosalicylic acid (5-ASA) in the dynamics of experimental ulcerative colitis (UC) in rats.Materials and methods. UC was simulated by cutaneous and then rectal application of a 3% solution of oxazolone. Original rectal suppositories with 1500ME of vitamin D3 were administered per rectum every 12 hours, in the comparison group with the same interval, rectal suppositories with 50 mg of 5-ASA. To assess the clinical status, the Disease activity index (DAI) scale was used, the serum concentration of IgG, IgM, IL-6, IL-8 was determined by the enzyme immunoassay using rat-specific test systems on days 2 and 6 of the experiment.The results of the study. In experimental UC, DAI rises, and the concentration of IgG, IgM, IL-8 and IL-6 in serum increases on the 2nd and 6th day of the experiment. DAI increases as serum concentrations of IgG, IgM, IL-8 and IL-6 increase. The use of vitamin D3 in UC leads to a decrease in DAI and serum concentrations of IgG, IgM, IL-8, IL-6 mainly on the 6th day of observation. The use of rectal suppositories with 5-ASA in UC leads to a decrease in DAI and the concentration of IgM, IgG, IL-6, IL-8 on the 2nd and 6th day of observation.Conclusion. The efficacy of rectal suppositories containing 1500 IU of vitamin D3 in experimental UC was found to be comparable with the use of rectal suppositories with 5-ASA based on the assessment of the clinical status and serum concentration of IgM, IgG, IL-6, IL-8.

Full textAbstract:
In Xenopus eggs, removal of small volumes of cytoplasm along with the surface (2-10% of the entire egg volume) causes very severe dorsal reduction (average DAI=1.4) when made at a site ventrally 30 degrees off the vegetal pole at 20% time of first cell cycle (0.2 NT). The greatest dorsal reduction (average DAI=1.1) occurs when removal is done at the vegetal pole at 0.3 NT, and intermediate reductions (average DAI=2.2-2.6) when done at sites dorsally, dorsolaterally or laterally 30 degrees off the vegetal pole at 0.4 NT. Removal at sites dorsally, dorsolaterally or laterally 60 degrees off the vegetal pole provokes slight dorsal reduction (average DAI=3.5-3.9) when made at 0.4-0.5 NT. Removal at all sites after 0.4 NT causes a steady decrease in the extent of dorsal reduction. By contrast, removal of larger volumes of dorsal cytoplasm (16-50% of the entire egg volume) causes a steady increase in the extent of dorsal reduction during first cell cycle with its maximum effect at 1.0 NT (average DAI=3.1). The surgery for the cytoplasmic removal does not affect cortical rotation. We conclude from these results that dorsal determinants are concentrated first in a small region ventrally 30 degrees off the vegetal pole by 0.2 NT, then move toward the vegetal pole during the period 0.2-0.3 NT and disperse to a broad region spanning over both the presumptive dorsal and ventral, but mainly the dorsal, hemispheres during the period 0.3-0.8 NT.

Abstract Rooted cuttings of Cotoneaster dammeri Schneid ‘Skogholm’ and seedlings of Rudbeckia fulgida Ait. ‘Goldsturm’ were potted into 3.8 liter (4 qt) containers in a pine bark:sand (8:1 by vol) substrate incorporated with 3.5 g (0.12 oz) N per container provided by one of the following five controlled-release fertilizers (CRFs): Meister 21N–3.5P–11.1K (21–7–14), Osmocote 24N–2.0P–5.6K (24–4–7), Scotts 23N–2.0P–6.4K (23–4–8), Sustane 5N–0.9P–3.3K (5–2–4) or Woodace 21N–3.0P–9.5K (21–6–12). Two hundred ml (0.3 in), 400 ml (0.6 in), 800 ml (1.1 in) or 1200 ml (1.7 in) of water was applied once daily (single) or in two equal applications with a 2 hr interval between applications (cyclic). Substrate solutions were collected from containers of cotoneaster 15, 32, 45, 60, 74, 90, 105, and 119 days after initiation (DAI). Irrigation efficiency [(water applied − water leached) ÷ water applied] was determined on the same days. Cyclic application improved irrigation efficiency at 800 ml (1.1 in) and 1200 ml (1.7 in) ≈ 27% compared to a single application. Irrigation efficiencies averaged over the season were 95%, 84%, 62%, and 48% for cotoneaster and 100%, 90%, 72%, and 51% for rudbeckia at 200 ml (0.3 in), 400 ml (0.6 in), 800 ml (1.1 in) and 1200 ml (1.7 in), respectively. NH4-N and NO3-N and PO4-P concentrations in substrate solution decreased with increasing irrigation volume regardless of CRF. Substrate NH4-N concentration decreased throughout the season with most CRFs below 5 mg/liter by 90 DAI. CRFs mainly affected substrate NH4-N and NO3-N concentrations when irrigated with 200 ml (0.3 in) or 400 ml (0.6 in). Substrate NH4-N, NO3-N, and PO4-P solution concentrations were similar for all CRFs at irrigation volume of 1200 ml (1.7 in). Osmocote, Scotts, and Woodace maintained relatively constant substrate solution levels of PO4-P through 60 DAI. By 90 DAI, substrate PO4-P levels were similar regardless of irrigation volume or CRF. Substrate PO4-P concentrations were never in the recommended range of 5 to 10 mg/liter when irrigated with 800 ml (1.1 in) or 1200 ml (1.7 in) regardless of CRF. Solution pH remained in the recommended range of 5.0 to 6.0 for all irrigation volumes and CRFs throughout the entire study with the exception of Sustane.

ABSTRACTPiperacillin in combination with tazobactam, a β-lactamase inhibitor, is a commonly used intravenous antibiotic for the empirical treatment of infection in intensive care patients, including burn patients. The purpose of this study was to develop a population pharmacokinetic (PK) model for piperacillin in burn patients and to predict the probability of target attainment (PTA) using MICs and concentrations simulated from the PK model. Fifty burn patients treated with piperacillin-tazobactam were enrolled. Piperacillin-tazobactam was administered via infusion for approximately 30 min at a dose of 4.5 g (4 g piperacillin and 0.5 g tazobactam) every 8 h. Blood samples were collected just prior to and at 1, 2, 3, 4, and 6 h after the end of the infusion at steady state. The population PK model of piperacillin was developed using NONMEM. A two-compartment first-order elimination PK model was finally chosen. The covariates included were creatinine clearance (CLCR), day after burn injury (DAI), and sepsis. The final PK parameters were clearance (liters/h) (equal to 16.6 × [CLCR/132] + DAI × [−0.0874]), central volume (liters) (equal to 25.3 + 14.8 × sepsis [0 for the absence or 1 for the presence of sepsis]), peripheral volume (liters) (equal to 16.1), and intercompartmental clearance (liters/h) (equal to 0.636). The clearance and volume of piperacillin were higher than those reported in patients without burns, and the terminal half-life and PTA decreased with the increased CLCR. Our PK model suggests that higher daily doses or longer durations of infusion of piperacillin should be considered, especially for burn patients with a CLCRof ≥160 ml/min.

Abstract:Background:vascular dementia (VaD) and mixed Alzheimer's disease (AD/VaD) are common. How best to monitor treatment is not clear. Our objective was to compare responsiveness and construct validity of change scores, following donepezil treatment, of the standardized Mini-Mental State Examination (sMMSE) and other measures potentially usable in primary care.Methods:A six-month, outcome measurement study. The Disability Assessment for Dementia (DAD), CLOX-1 and 2, Phonetic Fluency, a short Neuropsychiatric Inventory, (the NPI-Q), Clinical Global Impression (CGI) and the SymptomGuide™ (SG) were measured. Construct validity was tested by correlating change scores, and responsiveness by calculating standardized response means (SRMs).Results:Of 148 treated patients, 116 completed. The mean sMMSE increased by 0.7 (95% Confidence Interval (CI) = -0.005, 1.41; p=0.06; SRM= 0.15). There was no statistically significant difference in the DAD. The NPI-Q (-1.4; 95% CI = -2.08, -0.72; p<0.01; SRM=0.24), ClOX-1 (0.9; 95% CI = 0.19, 1.61; p<0.01; SRM=0.21), ClOX-2 (0.9; 95% CI = 0.17, 1.63; p=0.03; SRM=0.26), Phonetic Fluency (0.9; 95% CI = 0.19, 1.61; p=0.02; SRM=0.21) and SG (0.35; 95% CI = 0.20,0.51; p<0.01; SRM=0.28) each detected significant improvement. The CGI suggested improvement in 74 completers (64%) - mostly “minimal” (44/116, 38%) - while 21/116 (18%) were worse. Change scores at 24 weeks were at best modestly correlated with each other (range -0.22 to 0.30).Discussion:Different measures showed different responsiveness, in a setting in which the mean treatment effect seems to have been small, but clinically detectable. Patient-centered and executive function measures might be useful in vascular and mixed dementia.

Abstract A ready-made dry medium method for aerobic count, the Medi·Ca AC method, was compared to the AOAC Official Method 966.23, Microbiological Methods, for seven different heat-processed meat matrixes: cooked roast beef, Chinese barbecued pork (barbecued pork seasoned with honey-based sauce), bacon, cooked ham, frankfurter (made from beef and pork), and boiled and cooked pork sausage. The 95% confidence interval for the mean difference between the two methods at each contamination level for each matrix fell within the range of −0.50 to 0.50, and no statistical difference was observed at all three contamination levels for five matrixes. These results demonstrate that the Medi·Ca AC method is a reasonable alternative to the AOAC 966.23 method for cooked meat products.

Abstract. This paper presents a 10-bit tracking ADC using a multi-bit quantiser and a segmented current-steering DAC. The quantiser allows a dynamical adjustment of the step size dependent on the input signal waveform. This mitigates the limited slew rate of delta encoded ADCs. Energy consumption induced by 1 LSB ripple is removed by the quantiser. The segmented current-steering DAC allows simple control, good monotonicity and improved transient response when compared to previous design as well as potential power reduction.

To investigate the physiological roles of rutin (quercetin 3-O-rutinoside) and flavonol-3-glucosidase (f3g, a rutin-degrading enzyme) during cotyledon growth in tartary buckwheat, changes in rutin and quercetin (aglycone of rutin) concentrations, and f3g activities were measured. The rutin concentration gradually increased (about 50 mg g-1 DW cotyledons) up to 12 d after germination (DAG). The quercetin concentration in the tartary buckwheat cotyledon increased immediately after germination, reached a maximum at 4 DAG, and then remained around 1.5 mg g-1 DW until 12 DAG. The f3g activity in the cotyledon and testa decreased gradually after germination. However, it retained 80% activity at 4 DAG compared with dry seed. In addition, the f3g activity was high on the surface of the cotyledon. We also investigated spatial distribution of rutin and f3g activity in 4 DAG seedlings. While rutin was mostly present in the cotyledon, f3g activity was observed in the testa, the surface of the testa, and root. These results suggest that rutin and f3g activity in tartary buckwheat have different physiological roles during cotyledon growth compared with common buckwheat. Key words: Tartary buckwheat; rutin; quercetin; flavonoid; glucosidase; germination

Full textAbstract:
Aims Total hip arthroplasty (THA) using the direct anterior approach (DAA) is undertaken with the patient in the supine position, creating an opportunity to replace both hips under one anaesthetic. Few studies have reported simultaneous bilateral DAA-THA. The aim of this study was to characterize a cohort of patients selected for this technique by a single, high-volume arthroplasty surgeon and to investigate their early postoperative clinical outcomes. Methods Using an institutional database, we reviewed 643 patients who underwent bilateral DAA-THA by a single surgeon between 1 January 2010 and 31 December 2018. The demographic characteristics of the 256 patients (39.8%) who underwent simultaneous bilateral DAA-THA were compared with the 387 patients (60.2%) who underwent staged THA during the same period of time. We then reviewed the length of stay, rate of discharge home, 90-day complications, and readmissions for the simultaneous bilateral group. Results Patients undergoing simultaneous bilateral DAA-THA had a 3.5% transfusion rate, a 1.8 day mean length of stay, a 98.1% rate of discharge home, and low rates of 90-day infection (0.39%), dislocation (0.39%), periprosthetic fracture (0.77%), venous thromboembolism (0%), haematoma (0.39%), further surgery (0.77%), and readmission (0.77%). These patients were significantly younger (mean 58.2 years vs 62.5 years; p < 0.001), more likely to be male (60.3% vs 46.5%; p < 0.001), and with a trend towards having a lower mean BMI (27.8 kg/m2 vs 28.4 kg/m2; p = 0.071) than patients who underwent staged bilateral DAA-THA. Conclusion Patients selected for simultaneous bilateral DAA-THA in a single surgeon’s practice had a 3% rate of postoperative transfusion and a low rate of complications, readmissions, and discharge to a rehabilitation facility. Simultaneous bilateral DAA-THA appears to be a reasonable and safe form of treatment for patients with bilateral symptomatic osteoarthritis of the hip when undertaken by an experienced arthroplasty surgeon with appropriate selection criteria.

Dry matter and nutrient accumulation in the growing season are the main factors in the determination of seed yield and nutrient use efficiency. Field experiments were conducted with spring wheat (Triticum aestivum L.), barley (Hordeum vulgare L.) and oat (Avena sativa L.) in 1998 and 1999 at Melfort, Saskatchewan, Canada, to determine the biomass accumulation and plant nutrient uptake at different growth stages, and their relationship with days after emergence (DAE) and growing degree days (GDD). All crops generally followed a similar pattern of biomass and nutrient accumulation in the growing season, which increased continuously with growing time, with much faster increase at early growth stages than at late growth stages. Maximum biomass accumulation rate and amount usually occurred at late boot stage (46–47 DAE or 443–460 GDD) and ripening stage (89–90 DAE or 948–1050 GDD), respectively. Maximum rate of nutrient uptake occurred at tillering to stem elongation stages (22–36 DAE or 149–318 GDD). Maximum amount of nutrient uptake generally occurred at the beginning of flowering to medium milk stages (61–75 DAE or 612–831 GDD), except for P in 1998 when it occurred at late milk to ripening stages (80–90 DAE or 922–1050 GDD). In general, the maximum nutrient uptake rate and amount, respectively, occurred earlier than maximum biomass accumulation rate and amount. For various cereal species/cultivars, maximum biomass accumulation rate was 204–232 kg ha-1 d-1, and maximum uptake rate of N, P, K and S, respectively, was 3.2–5.7, 0.30–0.60, 3.85–7.05 and 0.45–0.60 kg ha-1 d-1. The findings suggest that a sufficient supply of nutrients from soil and fertilizers at early growth stages is of great importance for optimum crop yield.

Full textAbstract:
In this study, we investigated the effect of acute exposure to cyclosporine A (CyA) on renal vasodilations evoked by the DA1 dopaminergic agonist SKF38393 and whether dopamine DA1 receptors are directly involved in the interaction. Changes evoked by CyA in SKF38393 vasodilations were evaluated in phenylephrine-preconstricted isolated perfused rat kidneys in the absence and presence of SCH23390, a DA1 receptor antagonist. SKF38393 (3 × 10–8 to 3 × 10–6 mol) produced dose-dependent reductions in the renal perfusion pressure that were significantly attenuated in tissues pretreated with SCH23390 or CyA. Unlike SKF38393, the vasodilatory action of sodium nitroprusside, a nitrovasodilator, was not altered by CyA. The attenuating effect of CyA on SKF38393 vasodilations was preserved in preparations pretreated with SCH23390, suggesting that sites other than DA1 receptors may be involved in CyA–SKF38393 interaction. The study was then extended to investigate the possible involvement of renal α1-adrenoceptors in the interaction. Blockade of α1-adrenoceptors by prazosin (30 nmol/L) significantly reduced the vasodilatory effect of SKF38393 and virtually abolished the CyA-induced attenuation of SKF38393 responses. Further, CyA failed to alter SKF38393 vasodilations when the renal tone was raised with prostaglandin F2α (PGF2α), a vasoconstrictor whose effect is independent of α1-adenoceptors. Together, these findings support earlier reports that both DA1 and α1-receptors mediate the renal vasodilatory action of SKF38393 and suggest that CyA interacts selectively with the α1-receptor component to compromise SKF38393 responses.

The complement system is composed of a complex group of soluble proteins that have important roles in the immune response against foreign cells such as xenografted tissue cells. Activation of complement pathways results in the formation of the membrane attack complex (MAC). Several cell surface regulators known as membrane complement regulatory proteins (mCRPs) prevent the formation of MAC. For blocking the formation of MAC in the xenotransplanted cells, we tried to overexpress mCRPs in the endothelial cells to prevent the hyperacute rejection (HAR), because one of the major obstacles to xenotransplantation of vascularized organs was reported to be HAR. For this purpose, we isolated human MCP (membrane cofactor protein, CD46) (1.5 kb) and DAF (decay-accelerating factor, CD55) (1.1 kb) promoter regions from human genomic DNA isolated from the human embryonic kidney cell line HEK293, and cloned into pGL3 plasmid for luciferase reporter assay. We also inserted other known endothelial cell-specific promoters, such as Flk-1 (fetal liver kinase-1) and ICAM-2 (intercellular adhesion molecule-2), thrombomodulin promoters, into pGL3 vector to compare their promoter activities. We transfected the plasmids into several endothelial cell lines such as bovine aortic endothelial cells (BAEC), human umbilical vein endothelial cells (HUVEC), and mouse pancreatic microvascular endothelial cells (MS1). We also used two epithelial cell lines, human embryonic kidney epithelial cells (HEK293) and human epidermal keratinocytes (HaCaT). The endothelial specific expression of the promoters were compared with those of SV40, CMV, and EF-2a (elongation factor) promoters which are generally used in mammalian gene expression. Luciferase assays showed that among the endothelial cell-specific promoters, the 1.1 kb DAF promoter was the strongest, followed by the Flk-1 promoter. The promoter activity of 1.1 kb DAF was about 2-fold that of the Flk-1 promoter. Moreover, the 1.1 kb DAF and Flk-1 promoters were chosen as the best endothelial specific promoters, as both showed about 5 times more luciferase activity in the endothelial cells compared to that in the epithelial cell lines. We also found that the 5′-flanking region between −1126 and −968 of the 1.1 kb DAF promoter was very important for the endothelial-specific strong gene expression. On the 0.2 kb region of DAF promoter, we could detect several conserved nucleotide sequences interacting with the specific transcription factors, such as GATA-1, USF, CdxA, SRY, Sox-5, and Sp1. Interestingly, deletion of the GATA-1 motif between −1113 and −1104 reduced the promoter activity of the DAF promoter by about 25%. We conclude that the 1.1 kb DAF promoter is a suitable candidate promoter for strong endothelial cell-specific expression of mCRP genes.

Background: we report the clinical outcomes for femoral revision total hip replacement (THR) using the Direct Anterior Approach (DAA) interval. Methods: 149 patients (165 hips) with a mean age of 68.9 years (range, 33.2–91.0 years) and a mean follow-up of 4.2 years (1.1–8.9 years) were included. The indication for revision surgery was aseptic stem loosening in 131 (79.4%) hips, periprosthetic fracture in 29 (17.6%) hips, revision for stem malalignment in one (0.6%) hip, and prosthetic failure in four (2.4%) hips. Results: an endofemoral approach was used for 156 hips, and a Wagner transfemoral osteotomy was used for nine hips. An additional cup revision was done in 52 hips (uncemented cup: n = 29; cemented cup: n = 21; acetabular cage: n = 2). The overall complication rate was 14.5% (24 complications). Ten patients (10 hips) were revised (8 cups, 2 liners, 2 stems) with an average time to revision of 6 months (range, 3–23 months). The median preoperative Western Ontario McMasters Osteoarthritis Score (WOMAC) score was 52.5 (Inter Quartile Range (IQR): 33.3), which improved to 27.2 (IQR: 30) postoperatively (p < 0.01). Conclusion: use of the DAA achieved similar results when compared with other surgical approaches in terms of clinical outcomes and complications, including dislocation rate. These results suggest that femoral revision using the DAA interval can be a safe and reliable procedure.

Left ventricular (LV) remodeling, including cardiomyocyte necrosis, scar formation, LV geometric changes, and cardiomyocyte hypertrophy, contributes to cardiac dysfunction and mortality after myocardial infarction (MI). Although precise cellular signaling mechanisms for LV remodeling are not fully elucidated, Gq protein-coupled receptor signaling pathway, including diacylglycerol (DAG) and PKC, are involved in this process. DAG kinase (DGK) phosphorylates DAG and controls cellular DAG levels, thus acting as a negative regulator of PKC and subsequent cellular signaling. We previously reported that DGK inhibited angiotensin II and phenylephrine-induced activation of the DAG-PKC signaling and subsequent cardiac hypertrophy. The purpose of this study was to examine whether DGK modifies LV remodeling after MI. Left anterior descending coronary artery was ligated in transgenic mice with cardiac-specific overexpression of DGKζ (DGKζ-TG) and wild-type (WT) mice. LV chamber dilatation (4.12 ± 0.10 vs. 4.53 ± 0.32 mm, P < 0.01), reduction of LV systolic function (34.8 ± 8.3% vs. 28.3 ± 4.8%, P < 0.01), and increases in LV weight (95 ± 3.6 vs. 111 ± 4.1 mg, P < 0.05) and lung weight (160 ± 15 vs. 221 ± 25 mg, P < 0.05) at 4 wk after MI were attenuated in DGKζ-TG mice compared with WT mice. In the noninfarct area, fibrosis fraction (0.51 ± 0.04, P < 0.01) and upregulation of profibrotic genes, such as transforming growth factor-β1 ( P < 0.01), collagen type I ( P < 0.05), and collagen type III ( P < 0.01), were blocked in DGKζ-TG mice. The survival rate at 4 wk after MI was higher in DGKζ-TG mice than in WT mice (61% vs. 37%, P < 0.01). In conclusion, these results demonstrate the first evidence that DGKζ suppresses LV structural remodeling and fibrosis and improves survival after MI. DGKζ may be a potential novel therapeutic target to prevent LV remodeling after MI.

Dopamine (DA) modulates sodium excretion by the innervated kidney. To examine the role of DA in the denervated (DNX) kidney the effects of the DA1/DA2 antagonist cis-flupenthixol (group 2, n = 7) (10 nmol X kg-1 X min-1), given intravenously in saline-loaded Wistar-Kyoto rats after acute unilateral left DNX, were compared with a placebo group (group 1, n = 7) and a group that received the DA1 antagonist SCH 23390 (group 3, n = 7) at 2.5 nmol X kg-1 X min-1. Pentobarbital sodium anesthesia was employed. Adequacy of DNX was assessed by a natriuresis and decrease in renal norepinephrine content in the DNX kidney and an antinatriuresis in the innervated right kidney. Mean arterial pressure slightly decreased in the placebo group (group 1, 106.7 +/- 2.2 vs. 99.3 +/- 2.4 mmHg) and after cis-flupenthixol (group 2, 108.8 +/- 2.7 vs. 92.8 +/- 1.8 mmHg) but not after SCH 23390 (group 3, 105.6 +/- 1.6 vs. 103 +/- 1.1 mmHg). Glomerular filtration rate was not affected by placebo or SCH 23390 in the DNX or innervated kidney but did slightly decrease after cis-flupenthixol in the DNX kidney. Sodium and water excretion after drug administration differed among the groups. In the DNX kidney urine flow decreased only in group 2, whereas fractional sodium excretion decreased modestly (P less than 0.05 paired t test) with SCH 23390 (3.53 +/- 0.34 vs. 2.89 +/- 0.20%) markedly with cis-flupenthixol (3.18 +/- 0.50 vs. 1.21 +/- 0.18%) and was unchanged in the placebo group (3.25 +/- 0.61 vs. 3.45 +/- 0.45%).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract Abstract 23 Background: To date, all published studies assessing the effects of the new oral anticoagulants dabigatran (dabi) and rivaroxaban (riva) on coagulation assays have used normal pooled plasma spiked with known concentrations of anticoagulant and therefore do not reflect the variability expected from patients taking these medications. Methods: We collected citrated venous blood samples from patients taking either dabi (n=43) or riva (n=10) for management of either atrial fibrillation or acute venous thrombosis. All subjects were required to have taken at least 5 doses of drug in order to reflect steady-state conditions and informed consent was obtained. The interval between last dose and phlebotomy ranged from 1 – 18 hours. Platelet-poor plasma was prepared and using the STA-R.. coagulometer (Diagnostica Stago), the following assays were performed: PT/INR using Neoplastin Plus.. (NP) and Innovin.. (IN), aPTT (Actin.. FS), thrombin time (TT), clot-based protein S (PS) activity, free PS antigen, chromogenic protein C (PC) activity, clot-based antithrombin activity, Clauss fibrinogen, dilute Russell's viper venom time (DRVVT), and factor VIII (FVIII) activity at several dilutions (1:10 to 1:160). Hemoclot.. dilute thrombin time and STA.. -Rotachrom.. anti-Xa assays were performed for quantitation of dabi and riva drug levels, respectively, using Aniara commercial plasma calibrators. Results: Median INR levels for patients on dabi were 1.1 (IN) and 1.2 (NP) and for riva were 1.15 (IN) and 1.3 (NP). The proportion of subjects with INR levels above 1.3 for dabi were 15% (IN) and 28% (NP) and for riva were 0% (IN) and 40% (NP). Median aPTT levels were 42s dabi and 32.5s riva. Although 73% of patients on dabi had an elevated aPTT (>38s), 60% of these were only mildly elevated (39–45s). Only one subject on riva had an elevated aPTT. The TT was extremely sensitive to the presence of dabi, as 100% of treated subjects had an elevated TT (>20s) and 73% were above the linearity cutoff (>100s). All subjects on riva had normal TT. As shown in Figure 1A, the clot-based PS assay was affected markedly by dabi, with patients showing artificially high PS activity with increasing drug levels, but no such effect was observed for riva (Figure 1B). For both drugs, the PS free antigen and chromogenic PC assays were unaffected. Figure 1C shows dabi also caused false elevations in antithrombin activity, though it did not affect the Clauss fibrinogen assay, which uses a much higher concentration of thrombin. Riva had no discernable effect on the antithrombin and fibrinogen assays (data not shown). Figure 1D shows that increasing levels of both anticoagulants caused artefactual decreases in FVIII activity. Increasing dilutions of patient plasma caused progressive elevation of FVIII activity, with median activity levels nearly doubling between 1:10 and 1:160 dilutions for both dabi (0.65 to 1.28) and riva (0.81 to 1.41). Finally, the DRVVT assay was prolonged (>20% elevated versus normal plasma) for 86% of dabi and 60% of riva patient plasmas. No differences were noted for any of these results between dabi 110 mg (n=14) and 150 mg (n=29) dosing. Conclusions: For the assay platforms assessed in this study, the majority of patients taking dabi and riva had near-normal INR and aPTT levels. This is discrepant with results from studies using spiked plasma samples. Clinicians should be cautioned that normal INR and aPTT results do not rule out the presence of therapeutic anticoagulant levels and the results should not be used to guide clinical decisions. Clotting-based thrombophilia testing should be avoided for patients taking these medications due to assay interferences, particularly with dabigatran.

Abstract A new error bound for the linear complementarity problem (LCP) of Σ-SDD matrices is given, which depends only on the entries of the involved matrices. Numerical examples are given to show that the new bound is better than that provided by García-Esnaola and Peña [Linear Algebra Appl., 2013, 438, 1339–1446] in some cases. Based on the obtained results, we also give an error bound for the LCP of SB-matrices. It is proved that the new bound is sharper than that provided by Dai et al. [Numer. Algor., 2012, 61, 121–139] under certain assumptions.

It has been demonstrated that azo dyes, the xenobiotics widely use in industries, can pose threats to public health. 3,3'-diaminobenzidine (DAB), as a benzidine analogue, is generated from reduction of azo dyes by intestinal or environmental microorganisms. The compound was applied at doses of 0 and 100 mg N/kg into two soils of contrasting textural properties belonging among Haplic Calsisols (Juzdan soil) and Calcaric Cambisols (Shervedan soil) and the effects on N mineralization kinetics were evaluated. Kinetic behavior of N mineralization in either the control or the DAB-treated soils consistently followed first-order models. In the early 7–10 days of the incubation period, net N mineralization was adversely influenced by DAB. After the early 7–10 days of incubation, the accumulation of inorganic N was greater in DAB-treated soils than those of control soils. This finding indicated that the degradation of DAB was started. Potentially mineralizable N in Haplic Calsisols and Calcaric Cambisols were 1.1 and 1.4 times greater than those of controls, respectively. Similarly, initial potential rates of N mineralization in the DAB-treated soils were 1.3 and 1.1 times greater than those of controls, respectively. The potentially mineralizable N and initial potential rates of N mineralization in both soils were significantly (LSD, P < 0.05) increased when soils were treated with DAB. About 95 and 82% of the initial DAB-N were mineralized to inorganic N after 60 days of aerobic incubation, respectively. Overall, DAB can be a potentially toxic xenobiotic for soil N mineralization shortly after application and the rate of its inhibition or stimulation is time-dependent.

Full textAbstract:
The capacity to direct attention (CDA) is a pivotal facet of cognitive functioning that allows people to focus on trains of thought, complex tasks, and the daily business of life. According to a theoretical framework of directed attentional fatigue (DAF) and restoration, excessive demand for attention depletes CDA, a condition called DAF. Attentional demands are factors such as feelings of loss and worries that require intense or prolonged use of CDA and thus can lead to DAF. The purposes of this study were to determine reliability and validity for an instrument to measure attentional demands, the Attentional Demands Survey (ADS). The ADS was administered to 197 (142 females, 50 males) community-dwelling elderly (ages 65-98 years, M = 77). A factor analysis revealed 4 factors/subscales consistent with theorized domains. Internal consistency for each subscale ranged from .87 to .90 and test-retest reliability was .91. The ADS can be used to explore the relationships among attentional demands, CDA, and interventions to support and restore attentional functioning for elders.

Full textAbstract:
Introduction: Ceramic-on-ceramic couplings are an alternative bearing surface to reduce the problems related to polyethylene wear and debris. However, ceramic articulations have their own risk of unique complications: fracture, squeaking, or dislocation. Few studies have assessed the outcomes of ceramic-on-ceramic total hip arthroplasties (THA) by direct anterior approach (DAA). The aim was to evaluate the early complications and revision rate of ceramic-on-ceramic THA by DAA. Material: A retrospective single-center study of 116 consecutive THAs was performed by DAA (106 patients) with ceramic-on-ceramic bearing from January 2015 to February 2018 with a minimum 24 months of follow-up. No patients were lost to follow-up. The mean age was of 55.3 years ± 11.3. The same cementless acetabular shell with a Biolox Delta ceramic insert and head were used. The complication and revision rates were collected at the last follow-up. The positioning of the acetabular implant was assessed on standard radiographs. Postoperative clinical outcomes were assessed by the Harris Hip Score. Results: At a mean follow-up of 31.9 months ± 5.5, no THA was revised. Five patients had late complications: 3 squeaking (2.6%) and 2 psoas impingements (1.7%) and were managed conservatively. All patients had satisfactory bony ingrowth of acetabular component, with no radiolucent lines and no osteolysis. Eight patients (6.9%) had an anterior overhang of the cup. The mean overhang for these patients was 4.1 mm. 111 hips (96%) were perceived as forgotten or having no limitations. Conclusion: This ceramic-on-ceramic coupling and shell by DAA produced excellent clinical outcomes and implant survival rate at a minimum two-year follow-up study. No serious complication was observed during the follow-up.

Abstract Objective: To test the hypothesis that several dimensions of the self-perceived psychosocial impacts of dental esthetics are not associated with grades of malocclusion, oral health–related quality-of-life measures, and body self-image in adolescents. Materials and Methods: This cross-sectional study included a convenience sample of 301 adolescents (mean age 16.1 ± 1.8 years, 58.1% female subjects). Demographic data were collected and dental conditions were assessed. The Dental Aesthetic Index (DAI) was used for assessment of malocclusion and determination of orthodontic treatment needs. The short form of the Oral Health Impact Profile (OHIP-14), the Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ), and the Body Satisfaction Scale (BSS) were used to measure adolescents' self-perceived variables. Results: All variables (DAI, OHIP-14, and BSS) were correlated with PIDAQ (P < .001). Stepwise multiple regression analysis revealed significant associations (P < .001) of independent variables with the total score of PIDAQ (R2 = 0.29) and dental self-confidence (R2 = 0.30), social impact (R2 = 0.14), psychological impact (R2 = 0.23), and esthetic concern (R2 = 0.13). Conclusion: The hypothesis is rejected. A broad range of adolescents' self-perceived impact of dental esthetics is influenced by severity of malocclusion, oral health–related quality of life, and body satisfaction.

Come mestiere artistico e professionale, alcuni membri dell’élite intellettuale del paese videro la traduzione come un problema letterario e il traduttore fu valutato come un professionista specializzato. Le prime riflessioni sul tema le troviamo nella rivista Miscelánea di José María Heredia e, col passare del tempo, vedremo che i ragionamenti intorno alla traduzione cambiarono, al punto che alla fine del secolo Francisco Sosa pubblicò un commento analitico a proposito di tre traduzioni (spagnole e messicane) della Gerusalemme Liberata del Tasso.

O objetivo do presente trabalho foi verificar a validade do parcelamento da adubação potássica, bem como a época mais adequada de aplicação, no controle do superbrotamento e no desenvolvimento e produção de bulbos na cultura do alho vernalizado (cv. Roxo Pérola de Caçador). Foram instalados dois experimentos em estufa agrícola, em vasos de cimento amianto com capacidade para 55 L de terra. O experimento 1 consistiu de sete épocas de aplicação da metade da dose de potássio necessária para a cultura, aos 50, 60, 70, 81, 91, 101 e 111 dias após a emergência (dae), sendo que o experimento 2 consistiu da aplicação de quatro doses de potássio no plantio combinadas a outras quatro em cobertura, aos 81 dae. O parcelamento da adubação potássica em diferentes estádios de desenvolvimento não influenciou a produção de bulbos e o superbrotamento na cultura do alho. A absorção de potássio, cálcio e magnésio pelas plantas foi influenciada pela adubação potássica no plantio e em cobertura, observando-se um efeito antagônico do potássio sobre a absorção de cálcio e magnésio. A elevação no nível de potássio no solo por ocasião do plantio proporcionou aumento na produção de bulbos, sendo que esta não foi influenciada por variações na dose de adubação potássica em cobertura.

Full textAbstract:
Treatment of drug-resistant tuberculosis is lengthy, insufficiently effective, and toxic. Since 2016, the World Health Organization has recommended shorter treatment regimens (STR). We assessed effectiveness and predictors of drug adverse events (DAE) among patients treated with STR. There were 95 consecutive rifampicin-resistant patients enrolled in STR in Tashkent between June 2018 and September 2019. Of these, 66.3% were successfully treated, 17.9% suffered failed treatment, 7.4% died, 5.3% were lost to follow-up and 3.2% were not evaluated. No recurrence was identified in 54 patients after 12 months of successful treatment completion. There were 47 reported DAE: the incidence rate was 6.15 DAE per 100 person-months-of-treatment. Any DAE was reported in 38 (40%) patients and grade 3/4 DAE were recorded in 21 (22.1%) patients. Median time to DAE was 101 (interquartile range 64–139) days. The most frequently encountered DAE were gastro-intestinal disorders, followed by hepatotoxicity and ototoxicity. The most commonly offending drug inducing DAE was protionamide. The dose was temporarily interrupted in 55.3% of DAE, reduced in 8.5% of DAE and permanently withdrawn in another 8.5% of DAE. HIV status was the only predictor associated with increased hazard of DAE. In Uzbekistan STR showed moderate effectiveness and safety, although treatment failure was high.

In dieser Studie wird der Frage nachgegangen, welche Funktionen landeskundliche Visualisierungen in Lehrwerken für den DaF-Unterricht einnehmen. Dabei liegt der Fokus auf Funktionen in Bezug auf den Text, den Lernprozess und den Inhalt. Die methodologische Vorgehensweise der Studie bestand in einer Lehrwerkanalyse von vier in der tschechischen Sekundarstufe I verwendeten DaF-Lehrwerken und sechs Lehrerinterviews. Die Ergebnisse deuteten auf einige Defizite sowie Desiderata hin, die zum Schluss zusammengefasst werden.

Full textAbstract:
The Dissolved Air Flotation (DAF) process is very effective in removing low density floc particles for drinking water treatment. It is especially well known in removing turbidity and algae by flotation process. The micro-bubbles in the DAF process pick up small flocs, thereby turbidity materials and floated algae are removed efficiently. When air is substituted by ozone in the DAF process, the removal rates of water quality parameters are highly enhanced including turbidity and algae. The turbidity removal rate is enhanced by 1.1% while the removal rate of THMFP is increased by 11.7%. Other parameters such as TOC, and microbial agents are also removed greatly by using ozone instead of air in DAF system.

Full textAbstract:
The resolution of indirect immunoperoxidase methods for localizing antigens on the surface of plasma membranes of cultured cells was tested using dissociated monolayer cultures of ciliary ganglion neurons prelabeled with cationic ferritin. Clusters of ferritin were produced on the cell surface by warming the cells to 37 degrees C after the ferritin, rabbit anti-ferritin, and goat anti-rabbit immunoglobulin coupled to horseradish peroxidase had all been applied. Intense 3,3'-diaminobenzidine tetrahydrochloride (DAB) staining was limited to the regions immediately surrounding the ferritin clusters. The lateral spread of the DAB reaction product beyond the outer ferritin particles in each cluster averaged 54-81 nm in four experiments. A second type of increased density, coinciding with the thickness of the plasma membrane, was also seen. These stained plasma membranes extended 161-339 nm from the ferritin clusters.
