Analysis of a hyper-diverse seed dispersal network: modularity and underlying mechanisms
(Ecology Letters, 2011-08-01) [Artigo]
Mutualistic interactions involving pollination and ant-plant mutualistic networks typically feature tightly linked species grouped in modules. However, such modularity is infrequent in seed dispersal networks, presumably ...
Sperm Bundles in the Seminal Vesicle of the Crematogaster victima (Smith) Adult Males (Hymenoptera: Formicidae)
(Neotropical Entomology, 2014-06-01) [Artigo]
This study establishes the presence of spermatodesm in the seminal vesicles of sexually mature males of Crematogaster victima (Smith). In this species, the spermatozoa are maintained together by an extracellular matrix in ...
Depressive symptoms and level of physical activity in patients with Alzheimer's disease
(Geriatrics & Gerontology International, 2012-10-01) [Artigo]
Aim: The purpose of this study was to determine the presence of depressive symptoms in patients with Alzheimer's disease, to assess whether there was an association between physical activity level and depressive symptoms ...
Morphological analysis of colon goblet cells and submucosa in type I diabetic rats submitted to physical training
(Microscopy Research and Technique, 2012-06-01) [Artigo]
Colon layers, especially the submucosa, as well as the secretion of goblet cells are extremely important for the functioning and transit of substances in this organ. However, the damages arising from type I diabetes and ...
Ultrastructural alterations in colon absorptive cells of alloxan-induced diabetic rats submitted to long-term physical training
(Microscopy Research and Technique, 2012-10-01) [Artigo]
Absorptive cells have notable importance for proper function of the colon, absorbing water and nutrients. In type I diabetes, hyperglycemia leads to remarkable alterations in cell structure. In absorptive cells, such changes ...
Mode of Peroxisome Proliferator-Activated Receptor gamma Activation by Luteolin
(Molecular Pharmacology, 2012-06-01) [Artigo]
The peroxisome proliferator-activated receptor gamma (PPAR gamma) is a target for treatment of type II diabetes and other conditions. PPAR gamma full agonists, such as thiazolidinediones (TZDs), are effective insulin ...
Fructose-rich diet leads to reduced aerobic capacity and to liver injury in rats
(Lipids in Health and Disease, 2012-06-19) [Artigo]
The main purpose of this research was to investigate the alterations in the aerobic capacity and appearance of metabolic alterations in Wistar rats fed on fructose-rich diet. We separated twenty-eight rats into two groups ...
Effects of physical training with different intensities of effort on lipid metabolism in rats submitted to the neonatal application of alloxan
(Lipids in Health and Disease, 2012-10-15) [Artigo]
Background: Type 2 diabetes mellitus (T2DM) is a chronic disease that is characterized by insulin resistance. Its development is directly connected with the inability of insulin to exert its action, not just on carbohydrate ...
A influência do genótipo da ECA sobre a aptidão cardiovascular de jovens do sexo masculino moderadamente ativos
(Arquivos Brasileiros de Cardiologia, 2012-04-01) [Artigo]
FUNDAMENTO: O gene da enzima conversora de angiotensina (gene ECA) tem sido amplamente estudado em relação a fenótipos de aptidão cardiorrespiratória, contudo a associação do genótipo da ECA com corridas de meia-distância ...
Comportamento higiênico em cupins com diferentes nidificações
(2017-08-03) [Dissertação de mestrado]
A presença de cadáveres no interior dos ninhos dos insetos sociais pode propiciar a contaminação com patógenos e prejudicar a integridade da colônia. O comportamento higiênico frente a cadáveres é imprescindível na manutenção ...
