Predictors of functional capacity in coronary patients

Introduction: Functional capacity is a major determinant of morbidity, mortality and quality of life in most cardiovascular diseases. Understanding and identifying functional capacity predictors will allow fine-tuning of strategies and components of cardiac rehabilitation programs (CRP) in order to minimize disability and enhance patients social and vocational status. We aim to identify predictors of functional...

Quantitative evaluation of experimental choroidal neovascularization by confoca...

The objective of the present study was to develop a quantitative method to evaluate laser-induced choroidal neovascularization (CNV) in a rat model using Heidelberg Retina Angiograph 2 (HRA2) imaging. The expression of two heparan sulfate proteoglycans (HSPG) related to inflammation and angiogenesis was also investigated. CNV lesions were induced with argon laser in 21 heterozygous Zucker rats and after three w...

Cimento aluminoso e seus efeitos em concretos refratários magnesianos espineliz...

O uso de concretos refratários alumina-magnésia ligados por cimento aluminoso (CAC) apresenta vantagens decorrentes da presença de espinélio e de CA6 (CaO.6Al2O3), ambas formadas in-situ e acompanhadas de expansão. Estas fases possuem alta resistência a escórias básicas e ao choque térmico, propriedades estas imprescindíveis para aplicação em panelas siderúrgicas. Estudos anteriores mostraram que o teor de CAC ...

Avaliação in vitro do extrato hidroalcoólico (EHA) de alecrim pimenta (Lippia s...

Atualmente a fito medicina vem sendo usada no controle de diversas doenças parasitárias particularmente as parasitoses gastrointestinais. Objetivou-se com este estudo avaliar a eficácia do extrato hidroalcoólico (EHA) de Lippia sidoides Cham sobre o desenvolvimento de ovos de nematódeos gastrointestinais. O efeito ovicida foi determinado através de análise probabilística, modelo logístico, utilizados os softwar...

Changes in aromatic characteristics of loureiro and alvarinho wines during matu...

Changes in volatiles during maturation in bottles of monovarietal Vinhos Verdes wines from Loureiro and Alvarinho grape varieties, were followed by chemical and sensory analyses. Young wines and wines matured for 8 and 20 months were studied. The volatiles were determined by gas chromatography– mass spectrometry (GC-MS) after extraction on XAD-2 resin. Straight chain fatty acid ethyl esters and acetates of fuse...

Volatile and glycosidically bound composition of Loureiro and Alvarinho wines

Composition of Loureiro and Alvarinho wines from the Vinhos Verdes region, respecting free volatile compounds as well as glycosidically bound aroma precursors, was exhaustively determined by GC-MS after adsorption on XAD-2 resin. On the whole, were identified and quantified 120 volatile compounds in the free fraction and 77 glycosidically bound compounds, belonging to C6-compounds, alcohols, fatty acids ethyl e...

Use of antibacterial agents in an intensive care unit in a hospital in Brazil

It is essential to monitor the utilisation of antibacterial drugs in order to establish appropriate measures for their control. The pattern of usage of antibacterial drugs, and its association with indicators of hospital infection, has been investigated in a non-specialized adult intensive care unit (ICU) located in Santa Luzia Hospital (Brasília, DF, Brazil). The study was conducted between January 2001 and Ju...

The extended ADS/CFT correspondence

The correspondence between conformal covariant fields in Minkowski's space-time and isometric fields in the five dimensional anti-deSitter space-time is extended to a six-dimensional bulk space and its regular sub-manifolds, so as to include the analysis of evaporating Schwarzschild's black holes without loss of quantum unitarity.
