ABSTRACT The objective was to evaluate animal performance and nutritional characteristics of Brachiaria brizantha cv. BRS Piatã in two integrated systems, during the summer and winter, five years after the initial establishment of the area. The randomized block experimental design was adopted with treatments consisting of a control (five native trees per hectare) and an integrated crop-livestock-forestry (ICLF) system with 227 eucalyptus trees per hectare. Animal performance, canopy height, soil cover, forage mass (leaf, stem and senescent material), and forage nutritive value were evaluated. Differences between systems were observed in forage mass (total, leaf, stem and senescent material), soil cover and forage nutritive value in both seasons. Shading conditions provided by eucalyptus in the ICLF system lead to a reduction in forage mass and neutral detergent fiber content, and to an increase in crude protein and in vitro organic matter digestibility. However, no effect on animal performance was obtained. The presence of trees improves the forage nutritive value without impacting animal performance in integrated systems.
RESUMO O objetivo foi avaliar o desempenho animal e as características nutricionais de Brachiaria brizantha cv. BRS Piatã em dois sistemas integrados, durante o verão e o inverno, cinco anos após o estabelecimento inicial da área. O delineamento experimental em blocos ao acaso foi adotado com tratamentos constituídos por um controle (cinco árvores nativas por hectare) e um sistema integrado lavoura-pecuária-floresta (ILPF) com 227 eucaliptos por hectare. Desempenho animal, altura do dossel, cobertura do solo, massa de forragem (folha, caule e material senescente) e valor nutritivo da forragem foram avaliados. Diferenças entre os sistemas foram observadas na massa de forragem (total, foliar, caule e material senescente), na cobertura do solo e no valor nutritivo da forragem em ambas as estações. As condições de sombreamento proporcionadas pelo eucalipto no sistema ICLF levaram a uma redução na massa de forragem e no teor de fibra em detergente neutro e a um aumento na proteína bruta e na digestibilidade in vitro da matéria orgânica. No entanto, nenhum efeito no desempenho animal foi obtido. A presença de árvores melhora o valor nutritivo da forragem, sem impactar o desempenho animal em sistemas integrados.

Amyloidosis comprises a group of disorders that accumulate modified autologous proteins in organs, mainly the kidneys. Few studies have addressed the amyloid compartmental distribution and associated clinical outcomes. The aim of this study was to present a case series of renal amyloidosis correlating histopathological data with glomerular filtration rate (GFR) during kidney biopsy. We studied 53 cases reviewed by nephropathologists from 2000 to 2018 in a single kidney biopsy center in Brazil. GFR was estimated using the CKD-EPI formula. Cases were divided into Group A ≥60 and Group B <60 mL·min−1·(1.73 m2)−1 using the estimated GFR during kidney biopsy. Semiquantitative histopathological study was performed, including extension and distribution of amyloid deposits by compartments (glomeruli, tubulointerstitial tissue, and vessels). Statistical analyses were made to understand associations with lower GFR. No difference was seen for age, gender, proteinuria, hematuria, subtype of amyloid protein, arteriosclerosis, interstitial fibrosis/infiltrate, or glomerular and interstitial amyloid deposits. After a previous P value <0.1 in the descriptive analysis, the following variables were selected: globally sclerotic glomeruli, high blood pressure, and the extension of vascular amyloid deposition. A binary logistic regression model with GFR as the dependent variable showed history of hypertension and vascular amyloid to be robust and independent predictors of Group B <60 mL·min−1·(1.73 m2)−1. Beyond the histopathologic diagnosis of amyloidosis, a semiquantitative approach on renal biopsy could provide new insights. Vascular amyloid is an independent predictor of renal dysfunction in cases of renal amyloidosis.

ABSTRACT This research was carried out to validate the effectiveness of the Near-IR spectroscopy method in predicting intake and digestibility of DM and nutrients of diets for feedlot lambs, in order to compare with the conventional laboratory method. Samples of diets, ort,s and feces of forty Santa Ines lambs were subjected to both methods and analyzed for DM, MM, NDF, ADF, CP, and EE for future calculations for intake and digestibility. Most of the model's correlation coefficient was in the range of 0.66 to 0.81, being suitable for quantitative prediction. Highest values for CP content of 0.85 (diets) and 0.87 (orts) were observed. There were high correlations between the methods to predicting intake (average values of 0.93) and digestibility (average values of 0.93). Correlations between the variables obtained by the prediction of NIRS and the conventional method were adequate, showing that regardless of the method, the nutritional content of diets, orts and feces can be used to calculate the intake and digestibility of DM and nutrients of lambs’ diets. The Near-IR spectroscopy method is recommended for accuracy, speed and low cost compared to conventional method.
RESUMO O presente trabalho teve como objetivo validar a eficácia do método de espectroscopia de reflectância do infravermelho proximal (NIRS) em predizer o consumo e a digestibilidade da MS e nutrientes de dietas para cordeiros confinados, em comparação ao método convencional de laboratório. Amostras das dietas fornecidas, sobras e fezes de 40 cordeiros Santa Inês foram submetidas a ambos os métodos e analisadas quanto aos teores de MS, MM, FDN, FDA, PB e EE, para futuros cálculos do consumo e da digestibilidade. A maioria dos coeficientes de correlação do modelo ficou na faixa de 0,66 a 0,81, mostrando-se adequados para a predição quantitativa. Os maiores coeficientes foram observados para teores de PB das dietas (0,85) e sobras (0,87). Foram encontradas altas correlações entre os métodos na predição do consumo (média de 0,93) e digestibilidade (média de 0,90) das dietas. As correlações entre as variáveis obtidas pela predição do NIRS e pelo método convencional foram adequadas, demonstrando que, independentemente do método, os teores nutricionais das dietas, das sobras e das fezes podem ser utilizados para calcular o consumo e a digestibilidade da MS e dos nutrientes das dietas para cordeiros confinados, sendo recomendado o método NIRS pela precisão, pela rapidez e pelo baixo custo em relação ao método convencional.

Autosomal dominant tubulointerstitial kidney disease (ADTKD) is characterized by autosomal dominant inheritance, progressive chronic kidney disease, and a bland urinary sediment. ADTKD is most commonly caused by mutations in the UMOD gene encoding uromodulin (ADTKD-UMOD). We herein report the first confirmed case of a multi-generational Brazilian family with ADTKD-UMOD, caused by a novel heterozygous mutation (c.163G>A, GGC→AGC, p.Gly55Ser) in the UMOD gene. Of 41 family members, 22 underwent genetic analysis, with 11 individuals found to have this mutation. Three affected individuals underwent hemodialysis, one peritoneal dialysis, and one patient received a kidney transplant from a family member later found to be genetically affected. Several younger individuals affected with the mutation were also identified. Clinical characteristics included a bland urinary sediment in all tested individuals and a kidney biopsy in one individual showing tubulointerstitial fibrosis. Unlike most other reported families with ADTKD-UMOD, neither gout nor hyperuricemia was found in affected individuals. In summary, we report a novel UMOD mutation in a Brazilian family with 11 affected members, and we discuss the importance of performing genetic testing in families with inherited kidney disease of unknown cause.

ABSTRACT The aim of this research was to investigate the combination of glycerol with urea as the ruminal parameters, digestibility and quality of microbial mass. The work was conducted at the Animal Unit of Digestive and Metabolic Studies belonging to the Faculty of Agricultural Sciences and Veterinárias-FCAV/Unesp campus Jaboticabal. Six animals fitted with rumen cannulas Nellore were used to verify the parameters pH, ammonia nitrogen, digestibility, and microbial mass distributed in a 6x6 Latin square. Six diets with similar metabolizable energy and crude protein were formulated using the forage:concentrate ratio of 30:70. The roughage used was corn silage. The concentrates used were composed of corn, soybean hulls, sunflower meal, glycerin and urea. The treatments were: C = control, U = 1 % urea, G10 = 10 % glycerin, GU10 = 1 % urea and 10 % glycerol, G20 = 20 % glycerin and GU20 = 20 % glycerin and 1 % urea. Diets with glycerin had lower digestibility of NDF and hemicellulose. There was no influence of diets on the growth of rumen microorganisms, pH and ammonia nitrogen. Diets with 20 % glycerin in the diet dry matter decrease the population of rumen protozoa. The addition of glycerol decreases the digestibility of fibrous components of the diet.
RESUMO O objetivo desta pesquisa foi verificar a combinação de glicerina com ureia, quanto aos parâmetros ruminais, à digestibilidade e à qualidade da massa microbiana. O trabalho foi conduzido na Unidade Animal de Estudos Digestivos e Metabólicos, pertencente à Faculdade de Ciências Agrárias e Veterinárias-FCAV/Unesp, Câmpus de Jaboticabal. Seis animais da raça Nelore providos de cânulas ruminais foram utilizados para verificar os parâmetros pH, nitrogênio amoniacal, a digestibilidade e a massa microbiana, distribuídos em quadrado latino 6x6. Seis dietas com energia metabolizável e proteína bruta semelhantes foram formuladas, utilizando-se a proporção volumoso:concentrado de 30:70. O volumoso utilizado foi silagem de milho. Os concentrados utilizados foram compostos por milho, casca de soja, farelo de girassol, glicerina e ureia. Os tratamentos foram: C = controle; U = 1% de ureia; G10 = 10% de glicerina; GU10 = 1% de ureia e 10% de glicerina, G20 = 20% de glicerina e GU20 = 20% de glicerina e 1% de ureia. Houve influência das dietas no crescimento dos microrganismos ruminais, no pH e no nitrogênio amoniacal. Dietas com 20% de glicerina na matéria seca da dieta diminuem a população de protozoários ruminais. A inclusão de glicerina diminui a digestibilidade de componentes fibrosos da dieta.

Abstract An updated inventory of Brazilian seed plants is presented and offers important insights into the country's biodiversity. This work started in 2010, with the publication of the Plants and Fungi Catalogue, and has been updated since by more than 430 specialists working online. Brazil is home to 32,086 native Angiosperms and 23 native Gymnosperms, showing an increase of 3% in its species richness in relation to 2010. The Amazon Rainforest is the richest Brazilian biome for Gymnosperms, while the Atlantic Rainforest is the richest one for Angiosperms. There was a considerable increment in the number of species and endemism rates for biomes, except for the Amazon that showed a decrease of 2.5% of recorded endemics. However, well over half of Brazillian seed plant species (57.4%) is endemic to this territory. The proportion of life-forms varies among different biomes: trees are more expressive in the Amazon and Atlantic Rainforest biomes while herbs predominate in the Pampa, and lianas are more expressive in the Amazon, Atlantic Rainforest, and Pantanal. This compilation serves not only to quantify Brazilian biodiversity, but also to highlight areas where there information is lacking and to provide a framework for the challenge faced in conserving Brazil's unique and diverse flora.
Resumo Um levantamento atualizado das plantas com sementes e análises relevantes acerca desta biodiversidade são apresentados. Este trabalho se iniciou em 2010 com a publicação do Catálogo de Plantas e Fungos e, desde então vem sendo atualizado por mais de 430 especialistas trabalhando online. O Brasil abriga atualmente 32.086 espécies nativas de Angiospermas e 23 espécies nativas de Gimnospermas e estes novos dados mostram um aumento de 3% da riqueza em relação a 2010. A Amazônia é o Domínio Fitogeográfico com o maior número de espécies de Gimnospermas, enquanto que a Floresta Atlântica possui a maior riqueza de Angiospermas. Houve um crescimento considerável no número de espécies e nas taxas de endemismo para a maioria dos Domínios (Caatinga, Cerrado, Floresta Atlântica, Pampa e Pantanal), com exceção da Amazônia que apresentou uma diminuição de 2,5% de endemicidade. Entretanto, a maior parte das plantas com sementes que ocorrem no Brasil (57,4%) é endêmica deste território. A proporção de formas de vida varia de acordo com os diferentes Domínios: árvores são mais expressivas na Amazônia e Floresta Atlântica do que nos outros biomas, ervas são dominantes no Pampa e as lianas apresentam riqueza expressiva na Amazônia, Floresta Atlântica e Pantanal. Este trabalho não só quantifica a biodiversidade brasileira, mas também indica as lacunas de conhecimento e o desafio a ser enfrentado para a conservação desta flora.

The aim of this study was to evaluate the performance and blood parameters of Simmental dairy cows, supplemented with 2 g/day of ricinoleic acid (RA) in diet. Forty Simmental dairy cows in mid lactation, individually housed in stable type tie-stall, were used. The animals were randomly assigned to two treatments: 0 or 2 g of RA/animal/day. The experimental period consisted of 42 days divided into two 21-day. It was observed reduction in dry matter intake (DMI), increased milk, fat and FCM (fat corrected milk) yield, as well as increased of fat content of milk in cows that received RA in diets. No effects were observed for red and white blood cells and blood metabolites. Supplementation of RA improves performance of dairy cows in mid lactation.
O objetivo deste estudo foi avaliar o desempenho e os parâmetros sanguíneos de vacas leiteiras simental suplementadas com 2 g/ dia de ácido ricinoleico (AR) na dieta. Foram usadas 40 vacas leiteiras da raça Simental no meio da lactação, alojados individualmente em tie-stall. Os animais foram divididos aleatoriamente em dois tratamentos: 0 ou 2 g de RA/animal/dia, fornecido via concentrados. O período experimental consistiu de 42 dias, divididos em dois períodos de 21 dias. Foi observada a redução no consumo de matéria seca (CMS), aumento da produção de leite, gordura e produção corrigida 3,5 %, bem como um aumento do teor de gordura do leite em vacas que receberam AR na dietas. Nenhum efeito foi observado para os glóbulos vermelhos e brancos e metabólitos no sangue. Suplementação de AR melhorou o desempenho de vacas leiteiras no terço mèdio de lactação.

Happy emotional states have not been extensively explored in functional magnetic resonance imaging studies using autobiographic recall paradigms. We investigated the brain circuitry engaged during induction of happiness by standardized script-driven autobiographical recall in 11 healthy subjects (6 males), aged 32.4 ± 7.2 years, without physical or psychiatric disorders, selected according to their ability to vividly recall personal experiences. Blood oxygen level-dependent (BOLD) changes were recorded during auditory presentation of personal scripts of happiness, neutral content and negative emotional content (irritability). The same uniform structure was used for the cueing narratives of both emotionally salient and neutral conditions, in order to decrease the variability of findings. In the happiness relative to the neutral condition, there was an increased BOLD signal in the left dorsal prefrontal cortex and anterior insula, thalamus bilaterally, left hypothalamus, left anterior cingulate gyrus, and midportions of the left middle temporal gyrus (P < 0.05, corrected for multiple comparisons). Relative to the irritability condition, the happiness condition showed increased activity in the left insula, thalamus and hypothalamus, and in anterior and midportions of the inferior and middle temporal gyri bilaterally (P < 0.05, corrected), varying in size between 13 and 64 voxels. Findings of happiness-related increased activity in prefrontal and subcortical regions extend the results of previous functional imaging studies of autobiographical recall. The BOLD signal changes identified reflect general aspects of emotional processing, emotional control, and the processing of sensory and bodily signals associated with internally generated feelings of happiness. These results reinforce the notion that happiness induction engages a wide network of brain regions.

Costimulatory and antigen-presenting molecules are essential to the initiation of T cell immunity to mycobacteria. The present study analyzed by immunocytochemistry, using monoclonal antibodies and alkaline phosphatase-anti-alkaline phosphatase method, the frequency of costimulatory (CD86, CD40, CD40L, CD28, and CD152) and antigen-presenting (MHC class II and CD1) molecules expression on human lung cells recovered by sputum induction from tuberculosis (TB) patients (N = 22) and non-TB controls (N = 17). TB cases showed a statistically significant lower percentage of HLA-DR+ cells than control subjects (21.9 ± 4.2 vs 50.0 ± 7.2%, P < 0.001), even though similar proportions of TB cases (18/22) and control subjects (16/17, P = 0.36) had HLA-DR-positive-stained cells. In addition, fewer TB cases (10/22) compared to control subjects (16/17) possessed CD86-expressing cells (P = 0.04; OR: 0.05; 95%CI = 0.00-0.51), and TB cases expressed a lower percentage of CD86+ cells (P = 0.04). Moreover, TB patients with clinically limited disease (£1 lobe) on chest X-ray exhibited a lower percentage of CD86-bearing cells compared to patients with more extensive lung disease (>1 lobe) (P = 0.02). The lower expression by lung cells from TB patients of HLA-DR and CD86, molecules involved in antigen presentation and activation of T cells, may minimize T cell recognition of Mycobacterium tuberculosis, fostering an immune dysfunctional state and active TB.

There are few reports concerning the biological role and the mechanisms of interaction between proteinases and carbohydrates other than those involved in clotting. It has been shown that the interplay of enzymes and glycosaminoglycans is able to modulate the activity of different proteases and also to affect their structures. From the large number of proteases belonging to the well-known protease families and also the variety of carbohydrates described as widely distributed, only few events have been analyzed more deeply. The term "family" is used to describe a group of proteases in which every member shows an evolutionary relationship to at least one other protease. This relationship may be evident throughout the entire sequence, or at least in that part of the sequence responsible for catalytic activity. The majority of proteases belong to the serine, cysteine, aspartic or metalloprotease families. By considering the existing limited proteolysis process, in addition to the initial idea that the proteinases participate only in digestive processes, it is possible to conclude that the function of the enzymes is strictly limited to the cleavage of intended substrates since the destruction of functional proteins would result in normal tissue damage. In addition, the location as well as the eventual regulation of protease activity promoted by glycosaminoglycans can play an essential role in the development of several physiopathological conditions.

Heart transplantation is associated with rapid bone loss and an increased prevalence and incidence of fractures. The aim of the present study was to compare the bone mineral density (BMD) of 30 heart transplant (HT) recipients to that of 31 chronic heart failure (CHF) patients waiting for transplantation and to determine their biochemical markers of bone resorption and hormone levels. The BMD of lumbar spine and proximal femur was determined by dual-energy X-ray absorptiometry. Anteroposterior and lateral radiographs of the thoracic and lumbar spine were also obtained. The mean age of the two groups did not differ significantly. Mean time of transplantation was 25.4 ± 21.1 months (6 to 88 months). Except for the albumin levels, which were significantly higher, and magnesium levels, which were significantly lower in HT patients when compared to CHF patients, all other biochemical parameters and hormone levels were within the normal range and similar in the two groups. Both groups had lower BMD of the spine and proximal femur compared to young healthy adults. However, the mean BMD of HT patients was significantly lower than in CHF patients at all sites studied. Bone mass did not correlate with time after transplantation or cumulative dose of cyclosporine A. There was a negative correlation between BMD and the cumulative dose of prednisone. These data suggest that bone loss occurs in HT patients mainly due to the use of corticosteroids and that in 30% of the patients it can be present before transplantation. It seems that cyclosporine A may also play a role in this loss.

PURPOSE: To evaluate the prevalence of tobacco smoking among health workers, professores, nurses and students of Federal University of São Paulo and the acceptance of an institutional program for quitting smoking. METHODS: We analized the answers of a questionnairy with 51 questions, distributed to people from different categories. RESULTS: The total percentage of answered questionnaires was 48.6% (2613). The answers obtained from health workers were 37.3%, professors 49.0%, nurses 52.7% and students 76.5% The total percentage of smokers at UNIFESP was 15.5%: 23.7% for health workers, 18% for professors, 16% for nurses and 8.6% for students. There was no significant statistical difference between the prevalence of smoking among females (17.3%) and males (16.3%). The age of major prevalence of smoking was between 31 to 40 years (26.6%). For all ages, people who have university level smoked less, independent of sex. Eighty three percent (83%) of the UNIFESP workers and students are worried of being passive smokers. Between the smokers, 55% were thinking of quiting and 42% declared that need some help to quit. CONCLUSION: We concluded that educational programs and help for cessation at institutional level are necessary and well accepted at UNIFESP, and the completion of these programs will contribute to the obeying of the prohibitive laws of no smoking within the community.
OBJETIVO: O conhecimento da prevalência do tabagismo é necessário para a realização de programas institucionais adequados que visem a diminuição do número de fumantes. O objetivo do trabalho foi verificar a prevalência do tabagismo entre funcionários, docentes, enfermeiros e alunos da Universidade Federal de São Paulo e a aceitabilidade de um programa antifumo. PACIENTES E MÉTODOS: Foram analisadas as respostas obtidas a partir de um questionário contendo 51 questões, distribuídos para as diferentes categorias. RESULTADOS: A porcentagem total de questionários respondidos foi de 48,6% (2.613) sendo 37,3% para funcionários, 49,0% para docentes, 52,7% para enfermeiras e 76,5% para alunos. Verificou-se que a porcentagem total de fumantes na UNIFESP foi de 15,5%, sendo 23,7% entre funcionários, 18% entre docentes, 16% entre enfermeiros e 8,6% entre alunos. A faixa etária de maior prevalência de fumantes foi a de 31 a 40 anos (26,6%). Não houve diferença estatística entre a prevalência de fumantes entre homens e mulheres. Em ambos os sexos, para todas as faixas etárias, os indivíduos com maior nível de instrução fumavam menos. Das pessoas que responderam o questionário, 82,5% estavam preocupadas em serem fumantes passivas. Dos fumantes, 55% estão pensando em largar de fumar e 42% julgam precisar de algum tipo de ajuda. CONCLUSÃO: Programas educacionais e de cessação do tabagismo em nível institucional são necessários e bem aceitos na UNIFESP, devendo ser realizados para que as leis de restrição do fumo dentro da instituição sejam efetivamente cumpridas.

The species Phaleria testacea Say, 1824 (Coleoptera, Tenebrionidae) varies a lot in size, and its populations along the coast of Brazil, where it lives buried in sandy beaches, have temporal and geographical variation in density. In order to find out which factors were contributing to these variations, we sampled populations from three different areas in Rio de Janeiro, during summer and winter. Simultaneously, we made an analysis of the different substracts where the individuals were found, including their total fresh weight. The results show a significant difference in size of individuals between and within populations, when summer and winter were compared. There is also a positive association between the population density of P. testacea and the amount of "garbage" found at the study areas.
