introduction: during kidney and other organ's transplantation, the organ to be transplanted, must inevitably remain out of the body with little or no blood perfusion at all, for long period of time (ischemia). this causes the release of oxygen free radicals (ofr). reperfusion (reintroduction of blood flow) will further exacerbate the initial damage caused by the ischemic insult and may result i...
Background & Objective: Diabetes is a metabolic disorder caused by low secretion or resistant to the insulin action. Oxidative stress, an imbalance between the free radical production and antioxidant defense systems of the body, is strongly related to diabetes and its symptoms. The aim of the present study is to evaluate effect of regular swimming on antioxidant system in diabetes. Materia...
background: reservation of blood leads to blood wastage if the blood is not transfused. therefore, in some centers only blood type and screen are evaluated. in this study, the efficacy of a blood crossmatch-to-transfusion ratio was measured and then compared with the standard levels. methods: this prospective study was conducted during one year in a university hospital. during this period, 398 ...
Harmine is a harmal-derived alkaloid with antioxidant properties. The morphine produces free radicals and plays a key role in the pathogenesis of kidney disease. This study was designed to evaluate the effects of harmine against morphine- induced damage to the kidneys of rats. In this study, 64 male rats were randomly assigned to 8 groups: saline and morphine treated groups; harmine groups (5, ...
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
rested on sociocultural theory (sct), this study attempted to examine the effect of written corrective feedback (wcf) followed by producing written languaging on developing writing accuracy over new tasks. to this aim, two intact iranian efl classes at the low-intermediate level were randomly assigned to two experimental groups: direct (n = 25) and indirect (n = 25). both groups wrote on a numb...
the primary goal of the current project was to examine the effect of three different treatments, namely, models with explicit instruction, models with implicit instruction, and models alone on differences between the three groups of subjects in the use of the elements of argument structures in terms of toulmins (2003) model (i.e., claim, data, counterargument claim, counterargument data, rebutt...
background & objective: reduced blood flow due to obstruction in most cases is as a primary factor in pressure ulcer formation and create of bedsore. the aim of this study is design and manufacture a care system tissue under pressure based on variation blood flow at different depths in the tissue. material & methods: in manufacture of system two infrared light transmitter were located between o...
with the increasing population and the need for more food, as well as with the development of science and technology, human approach to unnatural and often chemical inputs to increase agricultural production has been a great expansion and problems such as increased cancers, chronic diseases has created environmental pollution. implementation of organic organic is a solution to these problems . ...
