Therefore we can't say for sure that it is the hysterectomy that is protective."

Males have one very large claw that they wave to attract females to their burrows and females visit several mal...UNC studies identify key genes involved in blood vessel development
.... "They are communicators between the blood vessel wall and bloodstream. They are the cells that determine what ablood vessel does. For example, during angiogenesis, when new blood vessels are being formed, it's the endothelial cells that determine where they go and how big they get." And as communicators...And the beat goes on: New insight into the genetics of congenital heart disease
...form, AVCD is characterized by a large hole in the wall (the septum) that partitions the heart into upper and lower chambers (atria and ventricles, respectively).

Because changes in the arterial wall compliance and autonomic function often precede the onset of HT, a team of researchers has sought to identify whether differences in these areas exist among young, health African-American males who show no evidence of hypertension and compared them w...Improving the body's 'homeland security' against TB
