BACKGROUND Hydrogen sulfide (H(2)S) therapy is recognized as a modulator of vascular function during tissue ischemia with the notion of potential interactions of nitric oxide (NO) metabolism. However, little is known about specific biochemical mechanisms or the importance of H(2)S activation of NO metabolism during ischemic tissue vascular remodeling. The goal of this study was to determine the...
Background: Few quantitative studies in our country have been conducted to investigate the status of cardiovascular fitness in firefighters. The objective of this study was evaluation of aerobic capacity and its relation with the lifestyle of firefighters. Methods: This study was conducted in 2014 and 165 male firefighters participated in the study. Information such as demographic data as wel...
Transient global ischemia is a neuronal insult that induces delayed cell death. A hallmark event in the early post-ischemic period is enhanced permeability of mitochondrial membranes. The precise mechanisms by which mitochondrial function is disrupted are, as yet, unclear. Here we show that global ischemia promotes alterations in mitochondrial membrane contact points, a rise in intramitochondri...
Neuroserpin, a recently identified inhibitor of tissue-type plasminogen activator (tPA), is primarily localized to neurons within the central nervous system, where it is thought to regulate tPA activity. In the present study neuroserpin expression and its potential therapeutic benefits were examined in a rat model of stroke. Neuroserpin expression increased in neurons surrounding the ischemic c...
In this paper, the authors analysed changes occurring during rehabilitation processes in patients after early stroke based on analysis of their upper limbs’ target-reaching movement and muscle co-activation. Ischemic often results reduced mobility extremities frequently is a cause for long-term disability. The ever-developing technology 3D miniaturisation equipment testing bioelectrical activit...
pharmacotherapy updates of recombinant tissue plasminogen activator (r-tpa) in acute ischemic stroke
conclusions due to considerable inter- and intra- heterogeneity among studies performed by other centers such as differences in study project, background, and population features, determining a pharmacotherapy model based on safe implementation of treatments in stroke or sits seem advantageous. results age, time of onset, systolic blood pressure, diabetes, stroke severity, co-morbidities and pr...
background: we intended to investigate the serum magnesium impact upon the disability after ischemic stroke. methods: a total of 67 ischemic stroke patients who less than 6 hours had passed from their attacks participated in this cross sectional study. we have measured their serum magnesium level and determined its correlation with their rankin disability score (rds) in the first 72 hours (rds0...
We recorded 60 DC-extracellular electrograms simultaneously from epicardial and intramural sites of the left ventricle of isolated perfused porcine and canine hearts during the first 15 minutes after occlusion of the left anterior descending coronary artery. During coronary occlusion, maximal current flow across the ischemic border occurred when normal cells had repolarized and ischemic cells h...
background: as yet migraine has been established as one of the risk factors for ischemic stroke. some of the factors have been assessed for the explanation of this relation. hyperhomocysteinemia is seen partly both in stroke and in migraine. this study was conducted to determine the mean plasma levels of homocysteine in ischemic stroke patients on the basis of migraine history.methods: this cro...
