Introduction: Cerebral ischemia-reperfusion causes complex pathological mechanisms that lead to tissue damage, such as neuronal apoptosis. Usnic acid is a secondary metabolite of lichen and has various biological properties including antioxidant and anti-inflammatory activities. This study aimed to investigate the neuroprotective effects of usnic acid on apoptotic cell death and apoptotic-relat...
Objective(s): Cerebral ischemia/reperfusion causes complex pathological mechanisms that lead to brain tissue damage. Usnic acid is a lichen secondary metabolite that has many different biological properties including anti-inflammatory and anti-oxidant activities. Therefore, the objective of the current study was to investigate the neuroprotective effects of usnic acid ...
Background: Cerebral ischemia/ reperfusion leads to programmed cell death or planned apoptosis. Hippocampus is a very sensitive tissue cerebral ischemia. Propofol an anesthesia that recently the use of this drug as neuroprotective has been considered. In study, effect propofol on CA2 and CA3 areas hippocampus following ischemia was investigated.
Background: Q10 coenzyme is a potent antioxidant in the mitochondrial membrane. Releasing the oxygen free radicals occurs in the cerebral ischemia. Using Q10 coenzyme causes strength against oxidative after injury of cerebral ischemia during reperfusion. Also CoQ10 plays an important anti-apoptotic role to reduce Caspase 3 as a key enzyme neuroprotective in apoptosis. According to the sensitive...
Introduction: Nucleobinding-2 (NUCB2) or nesfatin-1, a newly identified anorexigenic peptide, has antioxidant, anti-inflammatory, and anti-apoptotic properties. Brain ischemia-reperfusion induces irreversible damages, especially in the hippocampus area. However, the therapeutic effects of NUCB2 have not been well investigated in cerebral ischemia. This study was designed for the first time to i...
background: it is well known that the hippocampus, the ca1 pyramidal cells in particular, is selectively vulnerable during global cerebral ischemia. recently, it is observed that pentoxifylline has a neuroprotective effect. this study explored the pharmacological relationship between ischemia-induced cell death of the hippocampus and the efficacy of a vasodilator agent (pentoxifylline) in the p...
One of the newest methods to reduce cerebral ischemia damages is cell therapy. The aim of this study is to evaluate the effect of Sertoli cell transplantation on ischemia-induced injuries in animal models of stroke. Rats were divided into four groups: transplant+ischemia, ischemia, sham, and control. Sertoli cells were separated from the other testis of rats and cultured. Unilateral Sertoli cel...
Objective(s): According to recent the findings, sulfur dioxide (SO2) is produced by the cardiovascular system, influencing some major biological processes. Based on previous research, SO2 exhibits antioxidant effects and inhibits apoptosis following cardiac ischemia/reperfusion. Therefore, the objective of the current study was to examine the neuroprotective impact of SO2 following global cereb...

Background & Aims: Cerebral ischemia is known as a major worldwide problem and subsequent reperfusion leads to apoptosis or programmed cell death. Specific regions of the brain and specific types of neurons, including hippocampal CA1 pyramidal neurons are more sensitive in cerebral ischemia. Today cell therapy is one of the common treatments that spread among the researchers. In this study, we...
