First polymorphic microsatellite markers for the migratory goliath catfish Pseudoplatystoma tigrinum (Siluriformes: Pimelodidae), a commercially important resource in the Amazon Basin / Primeiros marcadores microssatélites polimórficos para o bagre migratório Pseudoplatystoma tigrinum (Siluriformes: Pimelodidae), um recurso comercialmente importante na Bacia Amazônica
The caparari (Pseudoplatystoma tigrinum) is a widely distributed species in the Amazon Basin. It has a high market value and it is commonly consumed by the local population. In order to protect the species from possible overfishing, there is a need for a better understanding of the population diversity, since knowledge regarding its biology is scarce, which makes it difficult to monitor. Seven microsatellite loci (simple sequence repeats – SSR) for the species were isolated and characterized in 46 individuals which were sampled in four locations from the Madeira River, in the Brazilian Amazon. The number of alleles per locus ranged from three to eleven. The observed and expected heterozygosity ranged from 0,326 to 0,705 and 0,322 to 0,758, respectively. No linkage disequilibrium between pairs of loci was detected. The seven microsatellite loci were additionally used for inter-specific amplification in other four species of Pseudoplatystoma. Therefore, this study contributes to the first molecular species-specific SSR markers, which can be used as a new tool for estimating the genetic variability of P. tigrinum and has potential for application in population-related studies
Biotransformation of digitoxigenin by Cochliobolus lunatus
The biotransformation of digitoxigenin (1) by Cochliobolus lunatus was investigated. The biotransformation reaction was carried out in a 4-day process, resulting in the isolation of four products, whose structures were elucidated as 1beta-hydroxydigitoxigenin (2), 7beta-hydroxydigitoxigenin (3), 8beta-hydroxydigitoxigenin (4) and digitoxigenone (5). The production of these derivatives under the employed conditions has never been described so far. This is also the first report on the production of compound 4 by a biotransformation reaction
Complex post-traumatic stress disorder (CPTSD), executive function and attachment
Studies conducted with children and adolescents suggest that long-term exposure to adverse events and the lack of emotional and psychosocial support can lead to complex traumatizing conditions (C_PSPT), providing difficulties that affect emotional regulation, cognition, interpersonal relationships and the constitution of identity. The aim of this essay is to reflect on about the cognitive, more specifically executive function abilities, emotional, and attachment dimensions in children, who have been exposed to the experience of violence
The effect of socio-demographic factors on mental health and addiction high-cost use : a retrospective, population-based study in Saskatchewan
Objective: A small proportion of the population accounts for the majority of healthcare costs. Mental health and addiction (MHA) patients are consistently high-cost. We aimed to delineate factors amenable to public health action that may reduce high-cost use among a cohort of MHA clients in Saskatoon, Saskatchewan. Methods: We conducted a population-based retrospective cohort study. Administrative health data from fiscal years (FY) 2009–2015, linked at the individual level, were analyzed (n = 129,932). The outcome of interest was ≥ 90th percentile of costs for each year under study (‘persistent high-cost use’). Descriptive analyses were followed by logistic regression modelling; the latter excluded long-term care residents. Results: The average healthcare cost among study cohort members in FY 2009 was ~ 19,000. Individuals with unstable housing and hospitalization(s) had increased risk of persistent high-cost use; both of these effects were more pronounced as comorbidities increased. Patients with schizophrenia, particularly those under 50 years old, had increased probability of persistent high-cost use. The probability of persistent high-cost use decreased with good connection to a primary care provider; this effect was more pronounced as the number of mental health conditions increased. Conclusion: Despite constituting only 5% of the study cohort, persistent high-cost MHA clients (n = 6455) accounted for ~ 35% of total costs. Efforts to reduce high-cost use should focus on reduction of multimorbidity, connection to a primary care provider (particularly for those with more than one MHA), young patients with schizophrenia, and adequately addressing housing stability
Perímetro abdominal se asocia a la ingesta de alimentos, factores sociodemográficos y de comportamiento entre los adultos en el sur de Brasil: un estudio basado en la población
Objective: The aim of this study is to investigate the abdominal perimeter determinants in adults who live in the city of Lages, Sc. Design: A population-based cross-sectional study in adults from 20 to 59 years-old of the urban area (n=2.022). The dependent variable is the abdominal perimeter, the independent variables are: age, skin color self-reported, marital status, number of children, per capita income, education, physical activity, smoking, nutrition, self-reported diabetes mellitus, high blood pressure, body weight index. The differences between the mean perimeters were tested using ANOVA test and multiple linear regression for confounding adjustment. Results: The response rate was 98.2%, 52.3% were women. The mean abdominal perimeter for men was 93.66 cm (SD 13.8) and for women 92.80 cm (SD 14.5). There was a positive association of abdominal circumference with age (p<0.001) and negative regarding education. The abdominal perimeter means were higher for those insufficiently active (p<0.001), for former smokers (p<0.001), for those who consumed meat without fat removal (p = 0.001), for those who consumed fruit less than 5 times a week (p<0.001) and for those who were overweight (p<0.001). Remained positively associated with changes in abdominal obesity, insufficient physical activity, smoking, former smoker and consumption of meat without fat removal. All proximal variables remained positively associated with abdominal perimeter. Conclusions: The results have confirmed that diet, lifestyle and sociodemographic conditions determine a different distribution in abdominal fat, it is needed actions to promote a healthy lifestyle312621628Objetivo: El objetivo de este estudio fue investigar los determinantes del perímetro abdominal en adultos que viven en la ciudad de Lages, SC. Diseño: Estudio transversal de base poblacional en adultos 20-59 años de edad, de la zona urbana (n= 2022). La variable dependiente fue el perímetro abdominal y las variables independientes fueron: edad, color de la piel auto dicho, estado civil, número de hijos, renta per cápita, nivel educacional, actividad física, tabaquismo, nutrición, diabetes mellitus auto dicho, presión arterial alta e índice de masa corporal. Las diferencias entre los promedios de perímetros se probaron a través de la ANOVA y de la regresión lineal múltiple, ajustada para los factores de confusión. Resultados: La tasa de respuesta fue de un 98,2%, de los cuales un 52,3% eran mujeres. El perímetro abdominal promedio para los hombres fue 93,66 cm (SD= 13,8 cm) y para las mujeres 92,80 cm (SD= 14,5). Hubo asociación positiva entre la circunferencia abdominal y la edad (p<0,001) y negativa entre la circunferencia abdominal y el nivel educacional. El promedio de perímetro abdominal fue más grande en personas insuficientemente activas (p<0,001), en los ex fumadores (p<0,001), en los que consumen carne sin la eliminación de grasa (p=0,001), en aquellos que consumían frutos menos de 5 veces a la semana (p<0,001) y en los que tenían sobrepeso (p<0,001). Se mantuvo una asociación positiva con los cambios en la obesidad abdominal, la insuficiente actividad física, el tabaquismo, ex fumador y el consumo de carne sin la eliminación de grasa. Todas las variables proximales se mantuvieron asociadas positivamente con el perímetro abdominal. Conclusiones: Los resultados confirman que la dieta, el estilo de vida y las condiciones sociodemográficas determinan una distribución diferente de la grasa abdominal, siendo necesarias acciones para promover un estilo de vida saludablesem informaçã
ANÁLISE DAS REPETIÇÕES MÁXIMAS ESTIMADAS ATRAVÉS DO TESTE DE UMA REPETIÇÃO MÁXIMA
A adequada prescrição do treinamento de força (TF) deve considerar o volume e a intensidade aplicada aos exercícios. Este experimento teve como objetivo verificar o número de repetições máximas (RM) realizadas em quatro exercícios nos percentuais de 60 e 80% de uma repetição máxima (1RM). A amostra foi constituída de 10 homens treinados (29,5 À 5,8 anos; 85,2 À 7,0 kg; 177 À 10 cm) que realizaram o teste de 1RM nos exercícios desenvolvimento (DS), tríceps na testa (TT), supino reto (SR) e rosca bíceps (RB). A análise estatística foi feita através do método descritivo. Os valores na intensidade de 60% de 1RM foram: DS = 15,1 À 3,7 RM; TT = 16,3 À 4,6 RM; SR = 16,9 À 4,7 RM; RB = 11,0 À 2,3 RM, e os valores obtidos na intensidade de 80% de 1RM foram: DS = 7,9 À 2,2 RM; TT = 8,8 À 3,4 RM; SR = 8,2 À 2,9 RM; RB = 5,0 À 2,2 RM. A partir dos resultados apresentados no presente experimento, pode-se observar que nem todos os exercícios e indivíduos apresentam a mesma média de RM para determinada carga. Sendo assim, seria mais adequada a prescrição do TF através de testes submáximos.
ANALYSIS OF THE ESTIMATED MAXIMUM REPETITIONS THROUGH ONE MAXIMUM REPETITION
Abstract: The appropriate prescription of the strength training (ST) should to consider the volume and the applied intensity to the exercises. This experiment had as objective verifies the number of repetitions maximum (RM) accomplished in four exercises in the percentile of 60 and 80% of a one maximum repetition (1RM). The sample was constituted of 10 trained men (29.5 À 5.8 years; 85.2 À 7.0 kg; 177 À 10 cm) accomplished the test of 1RM in the exercises shoulder-press (SP), triceps-extension (TE), bench-press (BP) and biceps-curl (BC). The statistical analysis was made through descriptive method. The values in the intensity of 60% of 1RM were: SP = 15.1 À 3.7 RM; TE = 16.3 À 4.6 RM; BP = 16.9 À 4.7 RM; BC = 11 À 2.3 RM, and the values obtained in the intensity of 80% of 1RM were: SP = 7.9 À 2.2 RM; TE = 8.8 À 3.4 RM; BP = 8.2 À 2.9 RM; BC = 5.0 À 2.2 RM. Starting from the results presented in the present experiment, can be observed that nor all of the exercises and individuals present the same average of RM for certain load. Being like this, it would be more appropriate the prescription of TF through submaximal tests
Differential brain and spinal cord cytokine and BDNF levels in experimental autoimmune encephalomyelitis are modulated by prior and regular exercise
The interactions between a prior program of regular exercise and the development of experimental autoimmune encephalomyelitis (EAE)-mediated responses were evaluated. in the exercised EAE mice, although there was no effect on infiltrated cells, the cytokine and derived neurotrophic factor (BDNF) levels were altered, and the clinical score was attenuated. Although, the cytokine levels were decreased in the brain and increased in the spinal cord, BDNF was elevated in both compartments with a tendency of lesser demyelization volume in the spinal cord of the exercised EAE group compared with the unexercised.

Prevalence and risk factors for bovine leptospirosis in Mato Grosso do Sul, Brazil
Foi investigada a prevalência de anticorpos antileptospira em fêmeas bovinas com idade igual ou superior a 24 meses, provenientes de 178 rebanhos de 22 municípios do estado de Mato Grosso do Sul, bem como identificados fatores de risco associados à infecção. Foram analisadas 2.573 amostras de soro sangüíneo por meio do teste de soroaglutinação microscópica perante 10 sorovares de leptospira. Títulos iguais ou superiores a 100 para um ou mais sorovares foram detectados em 1.801 fêmeas (98,8%) de 161 (96,5%) rebanhos. O sorovar Hardjo (65,6%) foi apontado como o mais provável, seguido do sorovar Wolffi (12,3%). Os resultados demonstram que a leptospirose bovina se encontra presente em todos os municípios estudados, com alta prevalência, tanto em animais como em rebanhos. Os fatores de risco identificados neste estudo e associados à infecção por bactérias do gênero lepstopira foram o tipo de exploração pecuária de corte e a raça Zebu. _____________________________________________________________________________________________________________ ABSTRACTThe prevalence of anti-Leptospira spp. antibodies was estimated for female cattle aged 24 months or older. The sample comprised 178 herds from 22 counties in the state of Mato Grosso do Sul, Brazil. The risk factors associated with the presence of infeccion were investigated. A total of 2,573 blood serum samples were tested against 10 leptospira serovars using the microagglutination test (MAT). Titers of 100 or higher for one or more serovars were detected in 1,801 females (98.8%) from 161 herds (96.5%). Serovar Hardjo (65.6%) was the most frequent, followed by serovar Wolffi (12.3%). These results suggest that bovine leptospirosis is widespread in all the counties under study, with a high prevalence both at the animal and the herd level. Beef farms and the Zebu breed were associated to the higher risk of herd infection by leptospiras
