...e bone marrow enzyme eNOS, which stimulated nitric oxide
production, helping to produce greater numbers of EPCs. However, local injection of the chemokine stromal cellderived factor 1 alpha (SDF-1alpha) was required to recruit these EPCs from the circulation to the wound site. The increased presence of EPC...

in females. Just how active an enzyme is depends on how it's phosphorylized, or turned on by adding ...
New study: Pycnogenol reduces heart failure
...ar remodeling induced by L-NAME by blocking nitric oxide
production, which leads to hypertension and finally cardiomyopathy,"said Watson. After a detailed investigation of the heart tissue, Watson found Pycnogenol supplementation to significantly enhance the connective collagen matrix of cardiac tissue....

...rometers in length. The unintentionally doped zinc oxide
(ZnO) nanowires are intrinsically n-type and complementary doping (both n-type and p-type doping) is essential for functional device applications. The recent breakthrough in the p-type doping in Wangs research group makes ZnO light-emitting diodes (L...
UCLA Nobel Laureate honored with membership in the American Philosophical Society
...oundbreaking discovery of the importance of nitric oxide
in cardiovascular health secured him the 1998 Nobel Prize. He found that nitric oxide
is produced in the blood vessels and controls the flow of blood by signaling vessels to expand and c...
Erectile dysfunction -- the canary in the mineshaft?
...reases in oxidative stress and decreases in nitric oxide
production which has been related to erectile dysfunction (ED). Researchers from France explored whether treatment with sildenafil a common pharmacologic treatment for ED could improve endothelial dysfunction in a rat model. Researchers administ...
Erectile dysfunction and lower urinary tract symptoms
...IC HYPERPLASIA (Abstract 1565) The role of nitric oxide
(NO) in the mechanism of erection is well known in the treatment of erectile dysfunction (ED). However, studies have also suggested a connection between the NO pathway in bladder and prostate smooth muscle regulation which may benefit benign prostat...

Study explains why patients with OSA are at higher risk for cardiovascular disease
...thelial cells would mean less production of nitric oxide
that is crucial to artery vasodilatation. The less nitric oxide, the higher potentially is the risk of hypertension and acute heart attack. CPAP treatment would likely restore the physiologic function of the lining of the blood vessels." For the st...

(sapphire). At the heart of each lamp is a small cavity, which penetrates the upper sheet of aluminum foil and the sapphire. Each lamp is approximately the diameter of a human hair, said visiting research scientist Sung-Jin Park, lead author of the p...
Stanford researchers track human stem cells transplanted into rat brain
... the iron particles, called superparamagnetic iron oxide
or SPIO, have been used for more than a decade to track cells in living animals, including in rat neural stem cells. If the point is to use the technique in humans, he and postdoctoral scholar Raphael Guzman, MD, wanted to make sure that the particle...
