Objective: To evaluate low-molecular-weight (LMW) DNA as possible prognostic biomarker in acute ischemic and hemorrhagic stroke. Methods:  LMW DNA samples were isolated from plasma and cerebrospinal fluid by phenol deproteinization, analyzed by gradient polyacrylamide electrophoresis and quantified by spectrophotometry. Results: Two common types of the stroke, ischemic and hemorrhagic, differ...

Introduction: Development of brain edema following focal cerebral ischemia exacerbates primary ischemic injury. Blood brain barrier (BBB) opening is an important part of edema named as vasogenic brain edema. In this study, quantitative alterations of BBB permeability is experimentally evaluated using transient focal cerebral ischemia in the rat. Methods: Two groups of male rats (ischemic and sh...

to determine the presence of anticardiolipin (acl) antibodies in patients with ischemic events, we designed a case-control study. we studied 33 patients with unstable angina, 33 male patients with myocardial infarction and 34 control subjects with no evidence of ischemic heart disease. plasma samples were assessed for igg anticardiolipin antibodies by enzyme-linked immunosorbent assay (elisa). ...

the anti-apoptotic gene bcl-2 is located in mitochondria, but it is uncertain whether its expression affects hepatocyte survival in ischemia/reperfusion (i/r) injury. this experiment was designed to evaluate the role of folic acid in expression of bcl-2 in i/r in rat liver. eighteen wister rats were divided into sham-operated controlgroup (c) (n=6), i/r group (n=6), folic acid treated group whi...

background: stroke is a heterogeneous disease with several risk factors. high sensitivity c-reactive protein (hscrp) is a marker for cardiovascular and cerebrovascular diseases. recent studies have shown that high hscrp level is a risk factor for ischemic stroke. the objective of our study was to investigate the association of high hscrp (> 3 mg/l) levels with ischemic stroke and its subtypes i...

background:  intravenous  recombinant  tissue plasminogen  activator  (rt-pa) is an approved  treatment for acute ischemic stroke within 4.5 h of symptoms onset. decompressive craniectomy (dc) has been  shown  as an effective  therapeutic  modality in malignant  middle cerebral  artery (mca) infarction. as rt-pa could result in hemorrhagic  complication during or after any surgery dc may be ass...

Introduction: Reactive oxygen species (ROS) have been suggested to play an important role in the myocardial damage induced by ischemia – reperfusion. One element believed to be activated by ROS and to contribute to the reduction of ROS production, is the uncoupling protein-2 (UCP2). The objective of this investigation was to explore the effect of myocardial ischemia reperfusion on cardiac UC...

abstract background: infectious agents such as chlamydia pneumonia or helicobacter pylori (h. pylori) have been linked to ischemic heart disease (ihd) as the epidemiologic studies have shown. other studies believed that raised plasma fibrinogen level has been claimed as a possible link between h. pylori infection and ihd. methods: an analytic cross-sectional study was undertaken on 261 patients...
