Researchers show that veins stiffen as we age
...cerin pill under the tongue of each participant to relax
the veins. In each case, they found that the tests had no effect on the response of the veins in either age group. "Thus, we think that the stiffening of our veins as we age is probably due to structural changes, such as a thickening of the vein wa...
Fast test for low blood flow in dogs detects early heart trouble
...is commonly used in stress testing, Lardo says, to relax
blood vessels in the muscle, which enhances the contrast between normal and abnormal regions of the heart. After being injected, each of the dogs had a 64-CT scan of its heart and then underwent the standard test for blood flow with chemical bead...
Study of gene transfer for erectile dysfunction shows promise
...uction of particular proteins. These proteins help relax
smooth muscle cells, the type of muscle found in the penis as well as in hollow organs such as the bladder. Relaxing the tissue allows the penis to fill with blood and become erect. Previous research has shown that more than 50 percent of men bet...
Toxic molecule may cause most common type of muscular dystrophy

muscles and heart rhythm abnormalities. When doxycycline was stopped, mice stopped producing toxic RNA and returned to normal, except in cases when the heart was severely damaged. So far, however, Mahadevan and other scientists can't explain exact...

Discovery Promises Simpler Therapy for Sickle Cell Disease
...h suggests that an inability of red blood cells to relax
blood vessels through the release of nitric oxide is a major factor behind the disease's primary symptoms -- including oxygen deprivation and blocked vessels that can lead to pain, clots and stroke. Thus, therapies that restore nitric oxide to blood ...
