Acidic and basic fibroblast growth factors (FGFs) share a wide range of diverse biological activities. To date, low levels of FGF have not been correlated with a pathophysiologic state. We report that blood vessels of spontaneously hypertensive rats are shown to be associated with a marked decrement in endothelial basic FGF content. This decrement correlates both with hypertension and with a de...

Endogenous periadventitial adipose-derived factors have been shown to contribute to coronary vascular regulation by impairing endothelial function through a direct inhibition of endothelial nitric oxide synthase (eNOS). However, our understanding of the underlying mechanisms remains uncertain. Accordingly, this study was designed to test the hypothesis that periadventitial adipose tissue releas...

Background & Aims: Multiple sclerosis (MS) is one of the chronic autoimmune diseases of the central nervous system with unknown etiology. The present study aimed to investigate the apoptosis and nitric oxide (NO) production of endothelial cells treated with serum of patients with MS and response to interferon beta (IFN- ) therapy. Methods: Human umbilical vein endothelial cells were treated wit...

Background—Pulmonary arterial hypertension is characterized by a progressive increase in pulmonary vascular resistance caused by endothelial dysfunction, inward vascular remodeling, and severe loss of precapillary pulmonary vessel cross-sectional area. Asymmetrical dimethylarginine (ADMA), an endogenous nitric oxide synthase inhibitor, and its metabolizing enzyme dimethylarginine dimethylaminoh...

OBJECTIVE To investigate the levels of endothelial constricting and dilating mediators in preterm infants with hypoxic-ischaemic encephalopathy and prospectively evaluate the association between levels measured during the perinatal period and the diagnosis of neurodevelopmental disorders at 3 years of age. METHODS This regional observational cohort study was conducted at the Azerbaijan Medica...

Increased release of endothelium-derived relaxing factor/nitric oxide has been proposed as the final common pathway for vasodilator responses to gram-negative lipopolysaccharide (endotoxin). To test this hypothesis, we examined endothelium-dependent and endothelium-independent vasodilator agents in vascular smooth muscle isolated from guinea pigs 16 hours after injection of saline (control grou...

Transient reduction in coronary perfusion pressure in the isolated mouse heart increases microvascular resistance (paradoxical vasoconstriction) by an endothelium-mediated mechanism. To assess the presence and extent of paradoxical vasoconstriction in hearts from normal and diabetic rats and to determine whether increased heme oxygenase (HO)-1 expression and HO activity, using cobalt protoporph...
