guanosine/stroke

Deprivation of oxygen and glucose for 5h induces apoptosis in SH-SY5Y neuroblastoma cell cultures. After combined glucose and oxygen deprivation (CGOD) addition of guanosine (100 microM), a non-adenine-based purine nucleoside, significantly reduced the proportion of cells undergoing apoptosis. To

After ischemic stroke, early thrombolytic therapy to reestablish tissue perfusion improves outcome but triggers a cascade of deleterious cellular and molecular events. Using a collaborative approach, our groups examined the effects of guanosine (Guo) in response to ischemic reperfusion injury in

Guanosine (GUO) is neuroprotective when administered acutely for the treatment of cerebral ischemia. The aim of the present study was to investigate whether delayed administration of GUO improved long‑term functional recovery following stroke, as well as to explore the potential underlying

Previously we have found that extracellular guanosine (Guo) has neuroprotective properties in in vitro and in vivo. Moreover, extracellular Guo significantly increased in the ipsilateral hemisphere within 2h following focal stroke in rats, and remained elevated for one week. Therefore, we

In an animal preparation of congestive heart failure in the dog, during the development of cardiac failure due to rapid right ventricular pacing we observed significant decreases in cardiac output and arterial pressure and increases in pulmonary arterial and right atrial pressure. We also observed a

Guanosine and adenosine are important neuromodulators in the brain and work in cooperation to mitigate the effects of stroke, traumatic injury, and other neurological events. Both purines can act on slow (minutes to hours) and rapid (milliseconds to seconds) time scales. A guanosine-adenosine

The objective of the present study was to estimate parameters of oxidative status in the cerebrospinal fluid in the course of ischemic stroke and in the prediction of recovery of neurological functions. Concentration of superoxide dismutase (SOD) as a marker of antioxidant adaptation, the secondary

BACKGROUND Stroke remains the leading cause of adult disability. Thus, it is imperative to develop restorative therapies for ischemic stroke designed specifically to treat the intact brain tissue to stimulate functional benefit. Therapies targeting amplification of brain repair processes with nitric

Our aim was to explore the preventive and therapeutic effects of sodium (±)-5-bromo-2-(α-hydroxypentyl) benzoate (brand name: brozopine, BZP) on stroke in Dahl Salt-sensitive (Dahl-SS) hypertensive rats. Dahl-SS rats were fed a high-salt diet to observe the effect of BZP on blood pressure, and

BACKGROUND The guanosine insertion/deletion polymorphism (4G/5G) of plasminogen activator inhibitor-1 (PAI-1) gene has been suggested as a risk factor for ischemic stroke (IS), but direct evidence from genetic association studies remains inconclusive even in Chinese population. Therefore, we

OBJECTIVE To assess the value of alpha-atrial natriuretic peptide (alpha-ANP), second messenger cyclic guanosine monophosphate (cGMP,) and endothelin as markers of myocardial depression in septic shock. METHODS Prospective observational study. METHODS Medical intensive care unit (ICU) of a

The peri-infarct region after ischemic stroke is the anatomical location for many of the endogenous recovery processes, and the molecular events in the peri-infarct region remain poorly characterized. In this study, we examine the molecular profile of the peri-infarct region on post-stroke day four,

We investigated the effect of chronic angiotensin-covering enzyme (ACE) inhibitor treatment on functional and biochemical cardiac parameters in stroke-prone spontaneously hypertensive rats (SHRsp). Animals were treated prenatally and, subsequently, up to the age of 20 weeks with the ACE inhibitor

Objective: To evaluate the therapeutic effect of the combined treatment with balance acupuncture therapy and exercise re-learning rehabilitation therapy and the impact on serum cAMP and cGMP in the patients with hemiplegia of cerebral

Apoptotic cell death has been implicated in Alzheimer's disease pathology and amyloid peptide induced neurotoxicity. We investigated the survival promoting effects of Propentofylline in two models of apoptotic cell death, nerve growth factor withdrawal and beta-amyloid mediated cell death in nerve
