The study was designed to compare the response pattern of plasma l-arginine and methylarginines to stent placement in patients with or without ST segment elevation myocardial infarction (STEMI). Two groups of patients with obstructive coronary artery disease (OCAD) undergoing percutaneous coronary

The purpose of this study is to investigate whether an oxygen/ozone (O(2)/O(3)) mixture protects the heart from acute myocardial infarction through local involvement of endothelial nitric oxide synthase (eNOS) and endothelial progenitor cells (EPCs). Male Sprague-Dawley rats were subject to 25-min

Dangkwisoo-San (DS) is an herbal extract that is widely used in traditional Korean medicine to treat traumatic ecchymosis and pain by promoting blood circulation and relieving blood stasis. However, the effect of DS in cerebrovascular disease has not been examined experimentally. The protective

In this study, we aimed to compare the effects of low- and high-quality cardiopulmonary resuscitation (CPR) on cardioprotection by induced hypothermia (IH) at 34 °C and examine whether extracellular signal-regulated kinase or endothelial nitric oxide synthase mediates this cardioprotection. Left

BACKGROUND Ischemic stroke is the most frequent cause of persistent neurological disability in Western societies. New treatment strategies are required and effective in vivo models are crucial to their development. METHODS The current study establishes a novel in vivo rat model of focal striatal

Nitric oxide (NO) and prostaglandins (PG) both possess the ability to induce vasodilatation and prevent the aggregation of platelets. The synthesis of these substances is increased following in vivo lipopolysaccharide (LPS) infusion, but their function during sepsis is incompletely understood. We

BACKGROUND Chronic hypoxia is a major component of ischemic diseases such as stroke or myocardial infarction. Drosophila is more tolerant to hypoxia than most mammalian species. It is considered as a useful model organism to identify new mechanisms of hypoxic tolerance. The hypoxic tolerance of

The acidic protein chromogranin A (CgA) is the precursor of several regulatory peptides generated by specific proteolytic processes. Human recombinant CgA NH(2)-terminal fragment STA-CgA(1-78) (hrSTA-CgA(1-78)), containing vasostatin-1 (CgA(1-76)) domain, exerts a negative inotropic effect and

Stroke is a lethal disease, but it disables more than it kills. Stroke is the second leading cause of death and the most frequent cause of permanent disability in adults worldwide, with 90% of survivors having residual deficits. The pathophysiology of stroke is complex and involves a strong

BACKGROUND Stroke patients with diabetes have a higher mortality rate, worse neurologic outcome, and more severe disability than those without diabetes. Results from clinical trials comparing the outcomes of stroke seen with intensive glycemic control in diabetic individuals are conflicting.

BACKGROUND Nitric oxide (NO) has been implicated as a mediator in myocardial ischemia/reperfusion (I/R) injury, but its functional properties have been conflicting. We investigated whether NO has a protective role against I/R injury. RESULTS Using endothelial NO synthase knockout (eNOS KO) mice,
