Objective(s): The alteration of glucose transporters is closely related with the pathogenesis of brain edema. We compared neuronal damage/death in the hippocampus between adult and young gerbils following transient cerebral ischemia/reperfusion and changes of glucose transporter-1(GLUT-1)-immunoreactive microvessels in their ischemic hippocampal CA1 region. Materials and Methods: Transient cere...

conclusions pretreatment with epo and application of ipc significantly ameliorated the renal injury induced by bilateral renal ir. however, both treatments attenuated renal dysfunction and oxidative stress in kidney tissues. there were no significant differences between pretreatment with epo or application of ipc. materials and methods twenty four male wistar rats were allocated into four exper...

Background. Stimulation of left ventricular (LV) receptors with sympathetic afferents generally results in reflex sympathoexcitatory responses. Stimulation of LV receptors with vagal afferents results in reflex sympathoinhibitory responses. Vagal afferents are known to be preferentially distributed to the inferoposterior (IP) wall of the LV. We tested the hypothesis that there is also a prefere...

background ischemic injury of the spinal cord during the surgical repair of thoracoabdominal aortic aneurysms might lead to paraplegia. although a number of different mechanisms have been proposed, the exact cause of paraplegia has remained unknown, hampering the development of effective pharmacologic or other strategies for prevention of this condition. a number of studies suggested that cyclo...

background & target: ischemia reperfusion injury is the tissue damage caused when blood supply returns to the tissue after a period of ischemia or lack of oxygen. in this study, the effect of pentoxyfylline on bcl2 gene expression changes and cell injury in kidney of rat following ischemia reperfusion were evaluated.methods: in this experimental study, 20 male wistar rats with average weight of...

The ubiquitin-proteasome system (UPS) is a catalytic machinery that targets numerous cellular proteins for degradation, thus being essential to control a wide range of basic cellular processes and cell survival. Degradation of intracellular proteins via the UPS is a tightly regulated process initiated by tagging a target protein with a specific ubiquitin chain. Neurons are particularly vulnerab...

Mitochondria are the key players of cardiac function and their dysfunction due to oxidative stress is implicated in myocardial ischemia reperfusion injury, one of the important mediators of cardiac mortality. The present study evaluates the mitochondrial protective effect of sodium thiosulfate on isolated cardiac mitochondria (interfibrillar mitochondria and subsarcolemmal mitochondria) subject...

Taurine is thought to be protective in ischemia due to its neuroinhibitory effects. The present aim was to assess the ability of taurine to attenuate glutamate release evoked by ischemia and to determine which component of this release is affected. The release of preloaded D-[(3)H]aspartate (a non-metabolized analog of glutamate) from superfused murine corticostriatal slices was used as index o...

Expression and activity of the germinal center kinase [corrected] SLK are increased during kidney development and recovery from renal ischemia-reperfusion injury. SLK promotes apoptosis, in part, via pathway(s) involving apoptosis signal-regulating kinase-1 and p38 mitogen-activated protein kinase. This study addresses the role of p53 as a potential effector of SLK. p53 transactivation was meas...

Major research efforts have been devoted to the discovery and development of new chemical entities that could inhibit the protein-protein interaction between HIF-1α and the von Hippel-Lindau protein (pVHL), which serves as the substrate recognition subunit of an E3 ligase and is regarded as a crucial drug target in cancer, chronic anemia, and ischemia. Currently there is only one class of compo...
