Objective(s) The brief interruption of cerebral blood flow causes permanent brain damage and behavioral dysfunction. The hippocampus is highly vulnerable to ischemic insults, particularly the CA1 pyramidal cell layer. There is no effective pharmacological strategy for improving brain tissue damage induced by cerebral ischemia. Previous studies reported that pentoxifylline (PTX) has a neuroprot...
BACKGROUND Postnatal overfeeding (OF) in rodents induces a permanent moderate increase in body weight in adulthood. However, the repercussions of postnatal OF on cardiac gene expression, cardiac metabolism and nitro-oxidative stress are less well known. METHODOLOGY/PRINCIPAL FINDINGS Immediately after birth, litters of C57BL/6 mice were either maintained at 10 (normal-fed group, NF), or reduc...
Relative levels of phosphate metabolites in the brain were examined in vivo by 31P magnetic resonance spectroscopy (MRS) in 50 Sprague-Dawley rats before, during, and after induction of focal permanent cerebral ischemia. After acquisition of baseline spectra, rats were subjected to injury within the core of the MR spectrometer, and 31P spectra were collected for 60 min after injury: in 7 rats, ...
OBJECTIVES Biochemical markers are important for the timely diagnosis and follow-up of ischemic events. Most of the markers have been previously studied in the context of cardiac ischemia. However, research on markers of non-cardiac events has been insufficient. Therefore, we investigated the relationship between troponin and myoglobin which are commonly used markers of cardiac ischemia, in non...
Background and Aim: Cardiovascular diseases are the leading cause of morbidity and mortality worldwide. Increased histamine level in the cardiac tissue has deleterious effects after ischemia-reperfusion occurrence. Regarding the existence of histamine type 2 receptors in the heart and their decisive role in inflammation, in the present study the cardioprotective effects of ranitidine in the fac...
objective(s) this study aimed to examine whether acetyl-l-carnitine (alc) was able to reduce cardiac arrhythmias and infarct size in the ischemic-reperfused isolated rat heart. materials and methods the isolated hearts were mounted on a langendorff apparatus then perfused by a modified krebs-henseleit solution during 30 min regional ischemia and 120 min reperfusion (control) or by enriched kreb...
