Sustained nitroglycerin (GTN) therapy impairs endothelial function in healthy volunteers and patients with cardiovascular disease, caused by an increase in vascular oxidative stress. This study aims to estimate the effect of rosiglitazone on vascular endothelial function in healthy volunteers continuously dosed to transdermal GTN (0.6mg/hr) for 7 days. To assess endothelial function, forearm bl...

Background: Gestational trophoblastic neoplasia (GTN) originates from placental trophoblast and is a highly chemosensitive and curable gynecologic malignancy. The present study was conducted to evaluate the effectiveness and safety of EMA/EP (etoposide, methotrexate, actinomycin-D, etoposide, and cisplatin) regimen in the treatment of high-risk GTN as well as patients’ outcome.  &nb...

PURPOSE Gestational trophoblastic neoplasia (GTN) is a highly treatable disease, most often affecting young women of childbearing age. This study reviewed patients managed for GTN at the Butaro Cancer Center of Excellence (BCCOE) in Rwanda to determine initial program outcomes. PATIENTS AND METHODS A retrospective medical record review was performed for 35 patients with GTN assessed or treate...

Nitric oxide (NO) has been implicated in the pathogenesis of migraine and treatment with its exogenous donor glyceryl trinitrate (GTN) represents widely accepted experimental "migraine model". In this study, glyceryl trinitrate was administered intraperitoneally to carps, serum nitrite and nitrate levels were determined, permeability of blood-brain barrier was investigated, and histological cha...

Clinical reports of kidney metastases derived from an invasive mole (IM) are rare. The present study presents the case of a 42-year-old woman who exhibited IM and bilateral kidneys metastases in what may be, to the best of our knowledge, the first report of such a case. Following an induced abortion, the patient initially experienced irregular vaginal bleeding and subsequently presented with le...

The nitroxyl anion (HNO) is emerging as a novel regulator of cardiovascular function with therapeutic potential in the treatment of diseases such as heart failure. It remains unknown whether tolerance develops to HNO donors, a limitation of currently used nitrovasodilators. The susceptibility of the HNO donor, Angeli's salt (AS), to the development of vascular tolerance was compared with the NO...

BACKGROUND In healthy humans, continuous treatment with nitroglycerin (GTN) causes nitric oxide synthase dysfunction, probably through the reduced bioavailability of tetrahydrobiopterin. Recent studies proposed that folic acid is involved in the regeneration of tetrahydrobiopterin in different disease states. Therefore, we investigated whether folic acid administration would prevent this phenom...

Mitochondrial aldehyde dehydrogenase (ALDH-2) was recently identified to be essential for the bioactivation of glyceryl trinitrate (GTN). Here we assessed whether other organic nitrates are bioactivated by a similar mechanism. The ALDH-2 inhibitor benomyl reduced the vasodilator potency, but not the efficacy, of GTN, pentaerythritol tetranitrate (PETN), and pentaerythritol trinitrate in phenyle...

Deep learning (DL) advances state-of-the-art reinforcement learning (RL), by incorporating deep neural networks in learning representations from the input to RL. However, the conventional deep neural network architecture is limited in learning representations for multi-task RL (MT-RL), as multiple tasks can refer to different kinds of representations. In this paper, we thus propose a novel deep...

In order to find an explanation for individual reactions to transdermal glyceryl trinitrate (GTN) we studied the skin temperature and hemodynamic reactions in 63 healthy persons. The data were obtained before and after the application of GTN and Glycerin (GL) placebo patches, during one hour. The skin temperature was measured on both forearms, the local (left sided) and systemic (right sided) r...
