Objective(s): Stroke is known as a main cause of mortality and prolonged disability in adults. Both transient receptor potential V1 (TRPV1) channels and toll-like receptors (TLRs) are involved in mediating the inflammatory responses. In the present study, the effects of TRPV1 receptor activation and blockade on stroke outcome and gene expression of TLR2 and TLR4 were assessed following permanen...
Background: Angiotensin II (Ang II) has an important role on cerebral microcirculation however, its direct roles in terms of ischemic brain edema need to be clarified. This study evaluated the role of central Ang II by using candesartan, as an AT1 receptor blocker, in the brain edema formation and blood-brain barrier (BBB) disruption caused by ischemia/reperfusion (I/R) injuries in rat. Methods...
Safranal is a monoterpene aldehyde found in saffron (Crocus sativus L.) petals. It has been previously reported that safranal has a wide range of activities such as antioxidant and anti-inflammatory effects. In this study, we examined the effect of safranal on brain injuries in a transient model of focal cerebral ischemia. Transient focal cerebral ischemia was induced by middle cerebral artery ...

Delayed Cerebral Ischemia (DCI) is a frequent and serious complication after Subarachnoid Hemorrhage (SAH), the leading cause of disability
In patients with cerebral ischemia, both during hospitalization and in the community, the prevalence of major depression is evident. Since the depression has a negative impact on recovery, its timely diagnosis and treatment is essential. This study aimed to evaluate the effect of the oral administration of Chevilan extract (Ferulago angulata hydroalcoholic extract; 100, 200 and 400 mg/kg) on br...
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...
Abstract Cerebral ischemia is an extremely complex disease that can be caused by a variety of factors. cause great harm to human body. Sevoflurane volatile anesthetic frequently used in clinic, and has lot advantages, such as quick induction general anesthesia, anesthesia recovery, no respiratory tract irritation, muscle relaxation, small cycle effect. The mechanism sevoflurane preconditioning ...
Objective(s): Carthamus tinctorius L. (CT) or saffloweris widely used in traditional Chinese medicine. This study investigated the effects of CT extract (CTE) on ischemia–reperfusion (I/R) brain injury and elucidated the underlying mechanism. Materials and Methods: The I/R model was conducted by occlusion of both common carotid arteries and right middle cerebral artery for 90 min followed by 24...
Introdution: Stroke is one of the most common diseases caused by occlusion or rupture of blood vessels in brain. It brings heavily loads for families and societies. Although some new strategies including treatment of tissue plasminogen activator have been applied in the clinic, these methods do not have perfect effect. Accordingly, more effective therapeutic strategies need to be developed...
