Nitroglycerin (glyceryl trinitrate; GTN) is the most prominent representative of the organic nitrates or nitrovasodilators, a class of compounds that have been used clinically since the late nineteenth century for the treatment of coronary artery disease (angina pectoris), congestive heart failure and myocardial infarction. Medline lists more than 15 000 publications on GTN and other organic ni...

Abstract We study the genuine tripartite nonlocality (GTN) and entanglement (GTE) of Dirac fields in background a Schwarzschild black hole. find that Hawking radiation degrades both physically accessible GTN GTE. The former suffers from “sudden death” at some critical temperature, latter approaches to nonzero asymptotic value limit infinite temperature. also effect cannot generate inaccessible ...

Anti-ischemic therapy with organic nitrates is complicated by tolerance. Induction of tolerance is incompletely understood and likely multifactorial. Recently, increased production of reactive oxygen species (ROS) has been investigated, but it has not been clear if this is a direct consequence of the organic nitrate on the vessel or an in vivo adaptation to the drugs. To examine the possibility...

Objectives: To examine the hypothesis that glyceryl trinitrate (GTN) may cause headache in patients with normal coronary arteries more often than in patients with obstructive coronary artery disease (CAD). This simple assessment may aid clinicians in the initial evaluation of chest pain syndrome and possible CAD. Patients and methods: 118 patients (66 men and 52 women) with new onset of chest p...

Glyceryl trinitrate (GTN) was previously reported to induce hepatocellular carcinoma (HCC) in rats after prolonged feeding. The present experiments were undertaken to evaluate the histogenesis and molecular biology of these tumors and the possible role of nitric oxide (NO), a GTN metabolite, in their development. Male F344 rats received a single i.g. intubation of GTN (1.2 g/kg) at 6 weeks of a...

OBJECTIVE To investigate the slope of linear regression of postevacuation serum hCG as an independent risk factor for postmolar gestational trophoblastic neoplasia (GTN). DESIGN Multicenter retrospective cohort study. SETTING Academic referral health care centers. PATIENT(S) All subjects with confirmed hydatidiform mole and at least four measurements of β-hCG titer. INTERVENTION(S) None...

OBJECTIVES The study evaluates the effect of atrial natriuretic peptide (ANP) compared with nitroglycerin (GTN) on left ventricular (LV) remodeling after first anterior acute myocardial infarction (AMI). BACKGROUND Compared with GTN, ANP suppresses the renin-angiotensin-aldosterone system and endothelin-1 (ET-1), which stimulate LV remodeling. METHODS Sixty patients with a first anterior AMI we...

OBJECTIVE To investigate digital microvascular responses to topical glyceryl trinitrate (GTN) in patients with primary Raynaud's phenomenon (PRP), limited cutaneous systemic sclerosis (LCSSc) and healthy control subjects, using laser Doppler imaging. METHODS Ten patients with PRP, 13 with LCSSc and 10 control subjects were studied. Baseline skin microvascular blood flow of the dorsum of the i...
