Cerebral hyperthermia during the rewarming phase of cardiopulmonary bypass (CPB) is associated with adverse outcomes. Cerebral hyperthermia can exacerbate a preexisting injury prior to rewarming, and may be damaging in itself. Temperature and cerebral metabolic rate (CMRO2) play a vital role in cerebral autoregulation. Therefore, hyperthermia can have a strong impact on cerebral oxygen transfer...

Toll-like receptor (TLR)-mediated signalling plays a role in cerebral ischaemia/reperfusion (I/R) injury. Modulation of TLRs has been reported to protect against cerebral I/R injury. This study examined whether modulation of TLR3 with poly (I:C) will induce protection against cerebral I/R injury. Mice were treated with or without Poly (I:C) (n = 8/group) 1 hr prior to cerebral ischaemia (60 min...

We evaluated the neuroprotective effects of systemically administered magnesium against N-methyl-D-aspartate (NMDA)-mediated brain injury in perinatal rats. Postnatal day (PND) 7 rats received unilateral intrastriatal injections of 25 nmol NMDA followed 15 min later by single or multiple doses of magnesium intraperitoneally (i.p.). Animals were sacrificed five days later and the severity of bra...

BACKGROUND AND PURPOSE Periprocedural embolization of debris during carotid stenting interventions may result in neurological deficit. This study was designed to evaluate in-hospital and 30-day adverse events in patients percutaneously treated for carotid artery disease with embolic protection devices. METHODS From 1999 to June 2002, a total of 442 consecutive patients underwent percutaneous ...

BACKGROUND Vascular damage caused by cerebral ischemia leads to edema, hemorrhage formation, and worsened outcomes in ischemic stroke patients. Therapeutic interventions need to be developed to provide vascular protection. The purpose of this review is to identify the pathophysiologic processes involved in vascular damage after ischemia, which may lead to strategies to provide vascular protecti...

Starting with the inaugural issue, we would like the AORTA journal to feature a special section, “Poll the Editorial Board,” in which readers ask questions and the journal provides a poll of answers from the Editorial Board. In this way, we hope to assess the thought and practice patterns of the Editorial Board. The question for the first issue was: Which method of cerebral protection do you fa...

background: leukemia inhibitory factor (lif) is a neurortophic cytokine which plays an important role in the neural cell survival. expression of lif and its receptor, lifr, in different brain regions has been demonstrated. based on evidences lif plays an important role in the modulation of neurogenesis and glial responses to injury. up-regulation of lif after central nervous system (cns) damage...

Although the major focus of recent cerebral protection research has been aimed at developing receptor-specific drugs, this effort has currently resulted in few improvements in patient outcome. Until advances in pharmacology translate to improvements in humans, the clinician and his patients will be well served by using more traditional techniques to prevent and treat cerebral ischemic events. T...

By analysing data on the age distribution of cerebral malaria among sites of different transmission intensities, we conclude that the most plausible explanation for the epidemiological patterns seen is that (i) cerebral malaria is caused by a distinct set of Plasmodium falciparum antigenic types; (ii) these antigenic types or 'CM strains' are very common and induce strong strain-specific immuni...
