Comparison of the antihypertensive effects of folic acid and resveratrol in spontaneously hypertensive rats combined with hyperhomocysteinemia

SAGE Open Medicine, 2023
Objectives: Studies have found that both folic acid and resveratrol have potential benefits in reducing complications of hypertension. The aim of this study was to compare the effects of resveratrol and folic acid on blood pressure in spontaneously ...

The Interplay Between Melatonin and Nitric Oxide: Mechanisms and Implications in Stroke Pathophysiology

Antioxidants
This work reviews the complex interplay between melatonin and nitric oxide (NO) in the central nervous system (CNS), with a detailed focus on its involvement in stroke pathophysiology. Melatonin, a neurohormone with potent antioxidant, anti-inflammatory,

Reduced expression of endothelial nitric oxide synthase in the lungs of patients with pulmonary hypertension.

New England Journal of Medicine, 1995
BACKGROUND Pulmonary hypertension is characterized by abnormal thickening of the pulmonary arteries and increased pulmonary vascular resistance. Nitric oxide is a potent endothelium-derived vasorelaxant substance and an inhibitor of smooth-muscle-cell ...

Exhaled Nitric Oxide and Nitric Oxide Synthase Expression in Hodgkin's Disease [PDF]

International Journal of Immunopathology and Pharmacology, 2009
Hodgkin's disease (HD) is a malignant lymphoma with frequent mediastinal involvement, characterized by a significant inflammatory infiltration. Exhaled Nitric Oxide (FENO), is present in healthy humans, and has been proven to be increased in eosinophilic diseases such as allergic asthma.

Lipopolysaccharide induces nitric oxide synthase expression and platelet-activating factor increases nitric oxide production in human fetal membranes in culture

Reproductive Biology and Endocrinology, 2004
Background Platelet-activating factor and nitric oxide may be involved in the initiation of human labour as inflammatory mediators. The aim of this study was to test whether platelet-activating factor and lipopolysaccharide were able to induce nitric ...

Nitric oxide synthases: structure, function and inhibition.

Biochemical Journal, 2001
This review concentrates on advances in nitric oxide synthase (NOS) structure, function and inhibition made in the last seven years, during which time substantial advances have been made in our understanding of this enzyme family.

Is there a relationship between endothelial nitric oxide synthase gene polymorphisms and ankylosing spondylitis?

Clinics, 2013
OBJECTIVE: Nitric oxide is produced by endothelial nitric oxide synthase, and its production can be influenced by polymorphisms of the endothelial nitric oxide synthase gene.

Investigations into potential extrasynaptic communication between the dopaminergic and nitrergic systems

Frontiers in Physiology, 2012
Nitric oxide is unconstrained by cell membranes and can therefore act along a broad distance as a volume transmitter. Spillover of nitric oxide between neurons may have a major impact on central nervous system diseases and particularly on ...

Nitric oxide synthases: regulation and function.

European Heart Journal, 2012
Nitric oxide (NO), the smallest signalling molecule known, is produced by three isoforms of NO synthase (NOS; EC 1.14.13.39). They all utilize l-arginine and molecular oxygen as substrates and require the cofactors reduced nicotinamide-adenine ...

Synthesis of N-(Methoxycarbonylthienylmethyl)thioureas and Evaluation of Their Interaction with Inducible and Neuronal Nitric Oxide Synthase

Molecules, 2010
Two isomeric N-(methoxycarbonylthienylmethyl)thioureas were synthesised by a sequence of radical bromination of methylthiophenecarboxylic esters, substitution with trifluoroacetamide anion, deprotection, formation of the corresponding isothiocyanates and
