ABSTRACT The objective of this study was to evaluate the effects of dietary supplementation of purified lignin on the performance, relative organ weights, serum metabolites, and gene expression profiles of broiler chickens subjected to cyclic heat stress (HS). At 22 days old, 280 broilers were distributed in a completely randomized design with four treatments, ten repetitions, and seven birds per experimental unit. The birds were subjected to daily cyclic HS. A high temperature of 32±1 °C was maintained for 10 h/day (08:00–18:00 h), while a temperature of 22±1 °C was maintained for the remaining time. Treatments were a basal diet or basal diet with the addition of 5, 10, or 15 g of purified lignin/kg of diet. Data were analyzed using one-way ANOVA and means were compared by Tukey's test at 0.05 significance. There was no effect of lignin supplementation on performance, carcass yield, relative weights of the bursa, spleen, and liver, or serum levels of glucose, triglycerides, uric acid, malondialdehyde, triiodothyronine, or tetraiodothyronine. The abundance of mRNA of heat shock protein 70, nuclear factor-κB, glutathione peroxidase, and Cu,Zn-superoxide dismutase in the liver was similarly unaffected by treatments. Purified lignin supplementation does not improve performance or the antioxidant response of broiler chickens subjected to HS.

Abstract Objective Estimate the level of functional capacity, self-reported diseases and the associated factors between community-dwelling elderly people; Methods This was a quantitative, descriptive, cross-sectional study conducted with 159 elderly people. We used the Brazil Old Age Schedule, Lawton and Brody scale, Katz index and a self-reported disease questionnaire; Results In the sample of 159 participants, it was observed that of the elderly people were between 60 and 70 years old, female, widowed, divorced or never married, could read and write, did not work and received minimum wage. For basic activities of daily living, having diabetes was the most important factor, with seven point thirty times the likelihood of been dependent. For instrumental and advanced activities of daily living, not been literate and suffering from stroke, respectively, were the most important factors; Conclusion Functional capacity was associated with osteoporosis and stroke and was correlated with self-reported diseases.

Resumen Objetivo Estimar el nivel de capacidad funcional, enfermedades autorreferidas y factores asociados entre ancianos de residencias geriátricas. Métodos Estudio cuantitativo, descriptivo y transversal realizado con 159 ancianos. Se utilizó el cuestionario Brazil Old Age Schedule (BOAS), la escala de Lawton y Brody, el índice de Katz y un cuestionario de enfermedad autorreferida. Resultados En la muestra de 159 participantes, 85 ancianos tenían entre 60 y 70 años, eran de sexo femenino, viudos, divorciados o nunca casados, sabían leer y escribir, no trabajaban y recibían salario mínimo. Para las actividades básicas de la vida diaria, tener diabetes fue el factor más importante, con 7.30 veces de probabilidad de ser dependiente. Para actividades instrumentales y avanzadas de la vida diaria, no estar alfabetizado y sufrir accidente cerebrovascular (ACV) fueron los factores más importantes, respectivamente. Conclusión La capacidad funcional fue asociada a la osteoporosis y ACV y estuvo relacionada con enfermedades autorreferidas.

Resumo Objetivo Estimar o nível de capacidade funcional, as doenças autorreferidas e fatores associados entre idosos comunitários. Métodos Estudo quantitativo, descritivo, transversal, realizado com 159 idosos. Foram utilizados o questionário Brazil Old Age Schedule (BOAS), a escala de Lawton e Brody, o índice de Katz e um questionário de doença autorreferida. Resultados Na amostra de 159 participantes, 85 idosos tinham entre 60 e 70 anos, eram do sexo feminino, viúvos, divorciados ou nunca casados, sabiam ler e escrever, não trabalhavam e recebiam salário mínimo. Para as atividades básicas da vida diária, ter diabetes foi o fator mais importante, com 7.30 vezes a probabilidade de ser dependente. Para atividades instrumentais e avançadas da vida diária, não ser alfabetizado e sofrer acidente vascular cerebral (AVC), respectivamente, foram os fatores mais importantes. Conclusão A capacidade funcional foi associada à osteoporose e AVC, e teve correlação com doenças autorreferidas.

O objetivo deste trabalho foi estimar a capacidade combinatória de 58 linhagens parentais de sorgo previamente selecionadas para tolerância ao Alumínio (Al). Cento e sessenta e cinco híbridos obtidos a partir do cruzamento destas linhagens foram avaliados em três níveis de saturação de Al. A saturação de Al reduziu a altura das plantas de sorgo, mas não alterou a data de florescimento dos híbridos. A Capacidade Geral de Combinação (CGC) das linhagens fêmeas foi significativa para todas as características. A CGC dos machos foi significativa somente para altura de plantas. A Capacidade Específica de Combinação (CEC) foi significativa somente para dias para florescimento. As linhagens com maior CGC para produção de grãos foram F7, F14, F17, F20, F21, F24, F29, F31, F41, F42, F48, F51, F54, e F55, sendo que F29, F48 e F51 também contribuíram para reduzir a data de florescimento dos híbridos. M2 foi a melhor linhagem-macho.

The purpose of this study was to estimate combining ability of 58 sorghum lines previously selected for Aluminum (Al) tolerance. One hundred sixty-five hybrids were evaluated at three levels of Al saturation (0%, 20% and 50%) at the same season. General Combining Ability (GCA) effects were significant for female lines for all three traits. GCA effects for male lines were significant only for plant height. Specific Combining Ability (SCA) effects were significant only for flowering time. The ratio GCA to SCA was greater than the unity, indicating the prevalence of additive effects for the control of Al tolerance. F7, F14, F17, F20, F21, F24, F29, F31, F41, F42, F48, F51, F54 and F55 lines contributed to increase yield, while F29, F48 and F51 also contributed to reduce flowering time. M2 was the best male line since it contributed to increase yield and plant height, and to reduce flowering time.
