Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.
Every 40 seconds someone in the United States has a stroke. Stroke is the fourth leading cause of death and the number one cause of adult disability in the country. While stroke often occurs without warning, understanding risk factors and learning to recognize symptoms can potentially save lives and limit damage if a stroke occurs. In recognition of National Stroke Awareness Month, Northwestern Medicine experts encourage consumers learn about their potential risk factors and start making lifestyle decisions that may decrease their likelihood of having a stroke.
Dr. Darja Marolt, an Investigator at The New York Stem Cell Foundation (NYSCF) Laboratory, is lead author on a study showing that human embryonic stem cells can be used to grow bone tissue grafts for use in research and potential therapeutic application. Dr. Marolt conducted this research as a post-doctoral NYSCF - Druckenmiller Fellow at Columbia University in the laboratory of Dr. Gordana Vunjak-Novakovic.
Contrast-enhanced ultrasound is an effective, noninvasive method for monitoring patients who undergo endovascular repair for abdominal aortic aneurysms, according to a new study published in the journal Radiology.
The link between psoriasis and cardiovascular events has been observed for years, however the mechanics were unknown. For the first time, Case Western Reserve University School of Medicine researchers have discovered preclinical evidence demonstrating that the inflammatory skin disease leads to cardiovascular disease. Further, the research demonstrated that aggressive reversal of psoriasis reduces the cardiovascular risk as well.
Sildenafil, also known as the erectile dysfunction drug Viagra, may give a boost to underdeveloped hearts in children and young adults with congenital heart defects. Researchers from The Children's Hospital of Philadelphia report that sildenafil significantly improved echocardiographic measures of heart function in children and young adult survivors of single ventricle heart disease palliation.
Researchers at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute, have developed a miniaturized biochip for investigating the effect of drugs on cancer stem cells (CSCs). Published recently in Nano Today, this new technology could boost the development of more effective cancer drugs.
A compound called rutin, commonly found in fruits and vegetables and sold over the counter as a dietary supplement, has been shown to inhibit the formation of blood clots in an animal model of thrombosis.
With the heart having limited ability to regenerate following injury, heart disease is the primary cause of morbidity and mortality in the developed world. Research impacting strategies for heart repair will be addressed during a lecture May 15 at the University of Houston (UH).
Patients with atrial fibrillation (A-fib) who cannot take blood thinners now have an alternative to reduce their risk of stroke, which is five times more common in people with the rhythm disorder. The non-surgical procedure works by tying off the left atrial appendage (LAA), the source of most blood clots leading to stroke in patients with A-fib. Northwestern Medicine- heart rhythm specialists from the Bluhm Cardiovascular Institute were the first to perform this procedure in Illinois.
Lung cancer is the leading cause of cancer death throughout the world. Standard treatment methods do not usually result in long-term recovery. In addition to the proliferation of the tumour cells, the growth of blood vessels controls tumors development. The blood vessel growth is controlled by several signalling molecules. Scientists from the Max Planck Institute for Heart and Lung Research in Bad Nauheim and Justus Liebig University Giessen have discovered a molecule that plays a key role in this process. They succeeded in reducing tumour growth in their experiments by blocking the phosphodiesterase PDE4.
Having a virtual copy of a patient's blood in a computer would be a boon to researchers and doctors. They could examine a simulated heart attack caused by blood clotting in a diseased coronary artery and see if a drug like aspirin would be effective in reducing the size of such a clot.
A new balloon catheter system could advance the endovascular approach to treating obstructed arteries in the leg, offering an alternative to surgical revascularization. Peripheral artery disease affects about 12 to 14 percent of the general population, and revascularization can be achieved through bypass surgery or a number of minimally invasive endovascular techniques that seek to reduce or eliminate symptoms of reduced blood flow by improving tissue perfusion.
The mantra in stroke care is "time is brain." With each passing minute more brain cells are irretrievably lost and, because of this, timely diagnosis and treatment is essential to increase the chances for recovery. While significant strides have been made to improve the response time of caregivers, a new study shows that a critical step in the process - imaging of the brain to determine the nature of the stroke - is still occurring too slowly at too many hospitals.
Using mathematical models, researchers in the Integrated Mathematical Oncology (IMO) program at Moffitt Cancer Center are focusing their research on the interaction between the tumor and its microenvironment and the "selective forces" in that microenvironment that play a role in the growth and evolution of cancer.
After nearly 13 years of study and intense debate, a pair of new papers from the Perelman School of Medicine, at the University of Pennsylvania have confirmed exactly how a once-popular class of anti-inflammatory drugs leads to cardiovascular risk for people taking it.
Novartis Pharmaceuticals Corporation announced today that the US Food and Drug Administration (FDA) approved Afinitor (everolimus) tablets for the treatment of adult patients with kidney tumors known as renal angiomyolipomas and tuberous sclerosis complex (TSC), who do not require immediate surgery.
Sickle cell disease (SCD), an inherited condition that causes red blood cells to sometimes deform into a crescent shape, affects an estimated 100,000 Americans, typically those of African descent. However, far more have sickle cell trait (SCT), caused when individuals carry just a single copy of the disease-causing mutation in their genes.
Chocolate, considered by some to be the "food of the gods," has been part of the human diet for at least 4,000 years; its origin thought to be in the region surrounding the Amazon basin. Introduced to the Western world by Christopher Columbus after his fourth voyage to the New World in 1502, chocolate is now enjoyed worldwide. Researchers estimate that the typical American consumes over 10 pounds of chocolate annually, with those living on the west coast eating the most. Wouldn't it be great if only chocolate were considered healthy?
A team led by a scientist from The Scripps Research Institute has been awarded a five-year, $10.2 million grant from the National Eye Institute (NEI) to develop a new type of treatment for diabetic retinopathy, macular degeneration, and other common vision disorders.
Researchers at UC have confirmed that fat surrounding the outside of arteries in humans-particularly the left coronary artery-may influence the onset of coronary artery disease, or atherosclerosis, which is the leading cause of death in the U.S.
