Corn texture and particle size in broiler diets
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2011-12-01)
The objective of this study was to evaluate the effect of corn texture and the particle size on broiler performance, carcass yield, nutrient digestibility, and digestive organ morphometrics. In Experiment I, 720 male Cobb ...
Production of leukotriene B4 by Paracoccidioides brasiliensis
(Wiley-Blackwell, 2012-06-01)
Paracoccidioides brasiliensis is the agent of paracoccidioidomycosis, the most prevalent deep mycosis in Latin America. The production of eicosanoids during fungal infection has been associated with the biology of these ...
Differential nutritional, endocrine, and cardiovascular effects in obesity-prone and obesity-resistant rats fed standard and hypercaloric diets
(Int Scientific Literature, Inc, 2010-01-01)
Background: This study tested whether rats with obesity induced by a hypercaloric diet (HD) present higher nutritional, endocrine, and cardiovascular disturbances compared with counterparts with obesity induced by overfeeding ...
Gas exchange rates at different vapor pressure deficits and water relations of 'Pera' sweet orange plants with citrus variegated chlorosis (CVC)
(Elsevier B.V., 2003-05-20)
Net photosynthesis (A) and transpiration rates (E), stomatal conductance (g), water use efficiency (WUE), intrinsic water use efficiency (IWUE) and internal leaf CO2 concentration (C) in response to different vapor pressure ...
In vivo uptake of a haem analogue Zn protoporphyrin IX by the human malaria parasite P. falciparum-infected red blood cells
(Portland Press, 2010-08-01)
The cellular traffic of haem during the development of the human malaria parasite Plasmodium falciparum, through the stages R (ring), T (trophozoite) and S (schizonts), was investigated within RBC (red blood cells). When ...
In silico network topology-based prediction of gene essentiality
(Elsevier B.V., 2008-02-01)
The identification of genes essential for survival is important for the understanding of the minimal requirements for cellular life and for drug design. As experimental studies with the purpose of building a catalog of ...
Genome-Wide Analysis of Differentially Expressed Genes During the Early Stages of Tomato Infection by a Potyvirus
(Amer Phytopathological Soc, 2009-03-01)
Plant responses against pathogens cause up-and downward shifts in gene expression. To identify differentially expressed genes in a plant-virus interaction, susceptible tomato plants were inoculated with the potyvirus Pepper ...
Interleukin-15 increases Paracoccidioides brasiliensis killing by human neutrophils
(Academic Press Ltd Elsevier B.V. Ltd, 2008-01-01)
Interleukin-15 is a cytokine produced by a wide range of different cell types, including macrophages, in response to lipopolysaccharide or microbial infection. This cytokine may play a crucial role in the activation of ...
Cytochemical characterization of the endomembranous system during the oocyte primary growth in Serrasalmus spilopleura (Teleostei, Characiformes, Characidae)
(Churchill Livingstone, 2005-10-01)
The morphophysiological changes that occur during oocyte primary growth in Serrasalmus spilopleura were studied using ultrastructural cytochemical techniques. In the previtellogenic oocytes endoplasmic reticulum components, ...
