quercetin/stroke

Heat stroke is characterized by hyperthermia, systemic inflammation, and multiple organ failure including arterial hypotension. This definition can be fulfilled by a rat model of heat stroke used in the present study. Anesthetized animals were exposed to heat exposure (43 °C for 70 min) and then

Heat stroke is a life-threatening illness characterized by an elevated core body temperature. Despite adequate lowering of the body temperature and support treatment of multiple organ-system function, heat stroke is often fatal. 3-(5'-Hydoxymethyl-2'-furyl)-1-benzyl-indazol (YC-1) been identified as

Catecholamines are endogenous amines that participate in the maintenance of cardiovascular system homeostasis. However, excessive release or exogenous administration of catecholamines is cardiotoxic. The synthetic catecholamine, isoprenaline (isoproterenol, ISO), with non-selective β-agonistic

Flavonoids, dietary components in vegetables, fruits and beverages, may protect against coronary heart disease, stroke and cancer. However, the bioavailability of these compounds is questionable. A previous study in ileostomy patients of the most abundant flavonoid, quercetin, suggested a 52%

OBJECTIVE To study the relation between intake of the antioxidant flavonoid quercetin and subsequent incidence of cerebrovascular disease (CVA). METHODS A cohort study carried out among 9208 Finnish men and women 15 y or more of age and initially free from cardiovascular disease. During a 28 y

Leaves of Acanthopanax senticosus (Rupr. et Maxim.) Harms (ASL) have revealed significant biological activity in the treatment of ischemic stroke diseases. However, there was no in-depth study of the therapeutic material basis and effect of ASL from the pharmacokinetics-pharmacodynamics (PK-PD)

BACKGROUND Epidemiological studies suggested that consumption of fruit and vegetables may protect against stroke. The hypothesis that dietary antioxidant vitamins and flavonoids account for this observation is investigated in a prospective study. METHODS A cohort of 552 men aged 50 to 69 years was

Heat shock protein 70 (Hsp70) preconditioning induces thermotolerance, and adenosine monophosphate (AMP)-activated protein kinase (AMPK) plays a role in the process of autophagy. Here, we investigated whether 17-dimethylaminoethylamino-17-demethoxy-geldanamycin (17-DMAG) protected against heat

Endothelial dysfunction is an early pathophysiological feature and independent predictor of poor prognosis in most forms of cardiovascular diseases. Epidemiological studies report an inverse association between dietary flavonoid consumption and mortality from cardiovascular diseases. In the present

To determine the role of proteasome proteolysis in the pathogenesis of hypertension, we have studied the proteolytic activity of the proteasome in the aorta and heart tissues of rats with spontaneous hypertension (line SHR), and used quercetin, the drug that can inhibit the activity of this

BACKGROUND Oxidative stress plays a significant role in stroke pathogenesis. Hence, plants rich in antioxidant phytochemicals have been suggested as effective remedies for prevention and treatment of stroke and other neurological diseases. Antiaris africana Engl. (Moraceae) is traditionally used for

A stroke is a severe life-threatening disease with high fatality and disability rate. This investigation aimed to study the effect of Xiaoyao-jieyu-san (XYJY) on post-stroke depression (PSD) and its potential mechanisms. PSD rats were prepared using middle cerebral artery embolization (MCAO) and

Beyond nutrition effect, quercetin is applied as a complement or an alternative for promoting human health and treating diseases. However, its complicated neuroprotective mechanisms have not yet been fully elucidated. This study provides evidence of an alternative target for quercetin, and sheds

Epidemiological studies suggest that the intake of flavonoids is inversely associated with risk of cardiovascular diseases and stroke, but there is no evidence showing the effect of flavonoids on vascular dementia. Because quercetin, a natural flavonoid, is known to scavenge free radicals, we

A stroke or cerebrovascular accident is a serious, life-threatening medical condition that occurs when the blood supply to part of the brain is severely reduced or cut off, depriving brain tissue of oxygen and nutrients. Studies suggested that level of gelatinases (MMP-2 and MMP-9) usually increases
