Background : Chronic Cerebral Hypoperfusion (CCH) is a common pathophysiological state that generally happens in conditions such as Alzheimer and vascular dementia, which both of them are known by cognitive impairment. The recognition of particular mechanisms in the chain of events from CCH to a cognitive deficit may identify potential targets for efficient therapies. The purpose of t...
a high number of people in the world suffered from spinal cord injury (sci). spinal cord injuries are happen due to falls from height, accidents, climbing, sports and etc. emergency care according to the standards not performed immediately after sci. a significant enhancement in the number of mortality and complications was observed every year. the aim of this study is to prevent the mortality,...
conclusions ferulago angulata extract, because of its antioxidant activities, is probably capable of removing free radicals and oxidant substances from brain and thus it can improve behavioral disorders in brain hypoperfusion ischemia model. results it was found that the administration of 400 mg/kg hydroalcoholic extract of f. angulate for two weeks after brain hypoperfusion ischemia increased ...
Chronic cerebral hypoperfusion due to carotid artery stenosis is a major cause of vascular cognitive impairment and dementia (VCID). Bilateral (BCAS) in rodents well-established model VCID where most studies have focused on white matter pathology subsequent deficit. Therefore, our aim was study the implication adult hippocampal neurogenesis hypoperfusion-induced mice, its relationship with defi...
BACKGROUND AND PURPOSE Hyperintense vessels on baseline FLAIR MR imaging of patients with ischemic stroke have been linked to leptomeningeal collateralization, yet the ability of these to maintain viable ischemic tissue remains unclear. We investigated whether hyperintense vessels on FLAIR are associated with the severity of hypoperfusion and response to thrombolysis in patients treated with in...
BACKGROUND AND PURPOSE Cerebellar hypoperfusion in the contralateral hemisphere after stroke is well studied and termed crossed cerebellar diaschisis. However, studies of hypoperfusion in the ipsilateral thalamus have been few. The purpose of this study was to investigate the prevalence of hypoperfusion and vasoreactivity to acetazolamide in the thalamus and cerebellum after stroke. METHODS W...
OBJECTIVE To demonstrate the prevalence of cerebral hypoperfusion without focal cerebral lesions in patients with Moyamoya disease (MMD), and the relationship between areas of hypoperfusion and cognitive impairment. METHODS Twenty-six MMD patients were included. Patients were categorized according to the presence/absence of hypoperfusion in the frontal, parietal, temporal, and occipital lobes...
Abdominal aortic aneurysm (AAA) involves the degradation of vascular fibres, and dilation rupture abdominal aorta. Hypoperfusion in walls due to stenosis vasa vasorum is reportedly a cause AAA onset induction adventitial ectopic adipocytes. Recent studies have reported that adipocytes are associated with both human hypoperfusion-induced animal models, highlighting pathological importance hypope...
BACKGROUND Persistent hyperlactatemia is particularly difficult to interpret in septic shock. Besides hypoperfusion, adrenergic-driven lactate production and impaired lactate clearance are important contributors. However, clinical recognition of different sources of hyperlactatemia is unfortunately not a common practice and patients are treated with the same strategy despite the risk of over-re...
