Nitric oxide (NO) is a small free radical with critical signaling roles in physiology and
pathophysiology. The generation of sufficient NO levels to regulate the resistance of the …

Cardiovascular disease remains the principal cause of death and disability among patients
with diabetes mellitus. Diabetes mellitus exacerbates mechanisms underlying …

Insulin has important vascular actions to stimulate production of nitric oxide from
endothelium. This leads to capillary recruitment, vasodilation, increased blood flow, and …

Regulated production of reactive oxygen species (ROS)/reactive nitrogen species (RNS)
adequately balanced by antioxidant systems is a prerequisite for the participation of these …

Since the observation that nitric oxide (NO) can act as an intercellular messenger in the
brain, the past 25 years have witnessed the steady accumulation of evidence that it acts pre …

Tetrahydrobiopterin (BH4) functions as a cofactor for several important enzyme systems, and
considerable evidence implicates BH4 as a key regulator of endothelial nitric oxide synthase …

Vascular nitric oxide (NO•) resistance, manifested by an impaired vasodilator function of NO•
in both the macro-and microvessels, is a common state in type 2 diabetes (T2D) associated …

The family of nitric oxide synthases (NOS) has significant importance in various
physiological mechanisms and is also involved in many pathological processes. Three NOS …

Blood vessels respond to changes in mechanical load from circulating blood in the form of
shear stress and mechanical strain as the result of heart propulsions by changes in …

Claudin-4 has been identified as an integral constituent of tight junctions and has been
found to be highly expressed in pancreatic cancer. The aim of the present study was to …
