Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.
Johns Hopkins Medicine researchers say a study designed to see if reducing the amount of anesthesia reduces the risk of postoperative delirium in older patients surprisingly found that lighter sedation failed to do so in severely ill people undergoing hip fracture repair.
Higher levels of oxidative stress in males results in lower levels of cofactor BH needed to make the powerful blood vessel dilator nitric oxide.
In the first such clinical trial in the United States, physician-scientists with the University of Maryland School of Medicine are investigating the use of MRI-guided focused ultrasound to open the blood-brain barrier.
Step aside carrots, onions and broccoli. The newest heart-healthy vegetable could be a gigantic, record-setting radish. In a study appearing in ACS' Journal of Agricultural and Food Chemistry, scientists report that compounds found in the Sakurajima Daikon, or "monster," radish could help protect coronary blood vessels and potentially prevent heart disease and stroke.
Adults in their early 60s, who spend less time sitting and more time engaged in light to vigorous physical activity, benefit with healthier levels of heart and vessel disease markers, according to new research in Journal of the American Heart Association, the Open Access Journal of the American Heart Association/American Stroke Association.
Key aspects of the aging of human cells can be reversed by new compounds developed at the University of Exeter, research shows.
Researchers from North Carolina State University and the University of North Carolina at Chapel Hill have developed a drug-delivery system that allows rapid response to heart attacks without surgical intervention.
Implantation of a stent-like flow diverter can offer one option for less invasive treatment of brain aneurysms – bulges in blood vessels – but the procedure requires frequent monitoring while the vessels heal.
A new drug-delivery technology which uses red blood cells to shuttle nano-scale drug carriers, called RBC-hitchhiking, has been found in animal models to dramatically increase the concentration of drugs ferried precisely to selected organs, according to a study published in Nature Communications this month by researchers from the Perelman School of Medicine at the University of Pennsylvania.
New knowledge about biological processes related to the heart's electrical activity has been gained through a major genome science study. The research had the largest sample size ever of a project of this type.
Arteries such as the aorta actively transport oxygenated blood, nutrients and cells throughout the body to keep our tissues functioning normally. Damage to the arteries can result in life-threatening cardiovascular diseases.
The use of ciprofloxacin and other antibiotics of the class of fluoroquinolones may be associated with disruption of the normal functions of connective tissue, including tendon rupture, tendonitis and retinal detachment
Prevencio, Inc., announces the publication of data that demonstrates a simple new blood test accurately diagnoses significant Peripheral Artery Disease, a circulatory problem in which plaque-narrowed arteries reduce blood flow to a patient's limbs and kidneys.
Patients with colorectal cancer tumors on the right side may have poorer five-year survival rates than those whose tumors are located on the left side.
Diabetes assessment currently relies on measurement of blood sugar levels -- but a simple saliva sample could replace this, says new research.
Traditionally, frailty is thought to be a syndrome of the elderly - one which comes as a natural and inevitable side-effect of aging, gradually transforming strong, healthy bodies into weaker, more delicate frames over time.
Ultrasound waves applied to the whole brain improve cognitive dysfunction in mice with conditions simulating vascular dementia and Alzheimer's disease.
University of North Carolina Lineberger Comprehensive Cancer Center scientists have uncovered a potential therapeutic target for kidney cancers that have a common genetic change.
Gestational diabetes may increase the risk of blood vessel dysfunction and heart disease in offspring by altering a smooth muscle protein responsible for blood vessel network formation.
Shape Memory Medical recently announced FDA clearance for U.S. marketing of their IMPEDE Embolization Plug, a technology funded by NIBIB and created to block irregular blood vessels.
