New research suggests that accumulation of amyloid-beta peptides in cerebral blood vessels causes vascular damage in Alzheimer's disease

New research suggests that accumulation of amyloid-â peptides in cerebral blood vessels, as opposed to the brain itself, may be a more important pathological mediator of Alzheimer's disease. Two independent yet related articles describe such findings in the August issue of The American Journal of Pathology.

White blood cell called a neutrophil appears to be crucial to abdominal aortic aneurysm formation

Each year, 200,000 Americans find out that the largest blood vessel in their body, the aorta, may burst open at any time. About 20,000 die suddenly from such a rupture. And another 36,000 have surgery to repair or replace the swelling section of aorta before time runs out.

Urine testing may predict birthmarks

Vascular anomalies - birthmarks caused by abnormal development of arteries, capillaries, veins or lymph vessels - can sometimes begin to progress, requiring aggressive treatment to save the child's health or vision. Research at Children's Hospital Boston now suggests that urine testing can help monitor these anomalies and predict those about to become a serious threat.

Viagra's non-blood pressure effect successfully mimics vasopressin action

Normally your kidneys filter about 50 gallons of blood a day, remove such waste as salts and minerals, and concentrate it into urine. When you exercise or don't take in water, your blood "thickens" and instead of removing water, the kidney reverses the process, pulls in water from the body that would normally go into the urine, and puts it into the blood, thus maintaining water balance.
