This transversal study aimed to analyze factors related to, and defining characteristics of, Impaired Tissue Integrity in persons with vascular ulcers, and compare the mean of these factors between the groups presenting different degrees in the severity of tissue compromise. The study was undertaken in February–August 2009, in the municipal health network of Goiânia in the state of Goiás, using...

BACKGROUND We hypothesized that the integrity of white matter might be related to the severity of freezing of gait in age-related white matter changes. METHODS Twenty subjects exhibiting excessive hyperintensities in the periventricular and deep white matter were recruited. The subjects underwent the Freezing of Gait Questionnaire, computerized gait analyses, and diffusion tensor magnetic res...

CONTEXT The role of macrostructural white matter changes, such as atrophy and white matter lesions, in cognitive decline is increasingly being recognized. However, in the elderly population, these macrostructural changes do not account for all variability in cognition. Measures reflecting white matter microstructural integrity may provide additional information to investigate the relation betwe...

BACKGROUND Reduced white matter (WM) integrity is a fundamental aspect of pediatric multiple sclerosis (MS), though relations to resting-state functional MRI (fMRI) connectivity remain unknown. The objective of this study was to relate diffusion-tensor imaging (DTI) measures of WM microstructural integrity to resting-state network (RSN) functional connectivity in pediatric-onset MS to test the ...

Background: Detection of sperm parameters based on conventional methods, immediately after thawing, have been revealed sperm capacity to in vivo and in vitro fertilization. But this evaluation is not fully reliable because of long journey of sperm during female genital tract to reach the oocyte and fertilize it. Therefore, analyzing postthawed sperm parameters after incubation is more beneficia...

Background: Alcohol abuse is considered as one of the problems associated with poor semen production and sperm quality. Both acute and chronic alcohol consumption may affect spermatozoal chromatin disorders through apoptosis. Therefore, for the first time, this experimental study was performed to evaluate the effect of ethanol consumption on sperm parameters and chromatin integrity of spermatoz...

Studies of radiation emissions from turbulent buoyant diffusion flames impinging on structural elements have applications to the development of fire models and estimation of structural integrity under large heat loads. An experimental and numerical study of radiation emissions from turbulent buoyant diffusion flames with and without impingement on a flat plate is reported. The steel plate was s...

A Data Warehouse (DW) is a data repository that integrates data from multiple sources and organizes the data according to a set of data structures called dimensions. Each dimension provides a perspective upon which the data can be viewed. In order to support an efficient processing of queries, a dimension is usually required to satisfy different classes of integrity constraints. In this paper, ...
