Emory Study Tests Bone Marrow Stem Cells to Improve Circulation in Legs

...provecirculation in patients with blockages in the arteries of their legs --a condition called peripheral vascular disease (PVD). Individuals with PVD have decreased blood flow to the muscles ofthe legs, especially during exercise, which causes pain, aching,cramping or fatigue in the muscles of their legs wh...

Weill Cornell Research Reveals Secrets Of Trafficking Within Cells

...ation to your brain, while cells in your heart and arteries work just as hard to keep that brain alive. Every one of these cells -- and others throughout the body -- depends on an internal process called endocytosis to keep the flow of cellular nutrients and information healthy and strong.

Scientists discover how fish evolved to float at different sea depths

...ea. The mechanism comprises of a complex system of arteries and veins, called the rete mirabile, and special blood proteins, which can release oxygen even at high oxygen concentrations. These systems drive oxygen from the blood into the swimbladder allowing the fish to float at different levels in the sea wi...

Rush Physicians Using Gene Therapy For Heart Patients With Moderate To Severe Chest Pains Who Do Not Benefit From Other Treatments

...y to place veins removed from the patient's leg or arteries taken from the patient's chest wall or arm to "bypass" the blocked blood vessels. While both of these treatments have been shown to be successful in relieving severe chest pains resulting from blocked arteries, a significant percentage of patients e...

Mystery Blood Vessel Disorder Implicated In 'Mini' Strokes

...anial arterial dolichoectasia, in which the larger arteries of the brain become elongated and misshapen. Typically, it has been considered a complication of atherosclerosis ("hardening of the arteries"), and not directly life-threatening. However, there is recent evidence that people with dolichoectasia are m...
