Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.
In humans, large arteries lose elasticity and thicken with age and other pathological conditions, leading to arteriosclerosis and high blood pressure.
A new study by researchers at the University of Eastern Finland provides novel insight into the previously unknown effects of factors regulating blood vessel formation.
Women aged 50 or younger who suffer a heart attack are more likely than men to die over the following 11 years, according to a new study published today (Wednesday) in the European Heart Journal.
While most COVID-19 cases are asymptomatic or mild, severe complications associated with acute respiratory distress have led to more than one million deaths worldwide in just several months.
Researchers from St. Petersburg provided a unique experiment. They implanted a polymer scaffold as a vascular prosthesis into the rat abdominal aorta and monitored the process of its bioresobtion for 16 months. An artificial vessel was formed where the scaffold was located.
A "danger molecule" is higher in the blood of younger black adults than whites, females than males and increases with weight and age, researchers report in the first large, longitudinal study associating circulating HMGB1 levels with obesity, inflammation promoters and early indicators of cardiovascular risk in humans.
Focused ultrasound waves help ETH researchers to deliver drugs to the brain with pinpoint accuracy, in other words only to where their effect is desired. This method is set to enable treatment of psychiatric and neurological disorders and tumors with fewer side effects in the future.
Scientists at Boston University's National Emerging Infectious Diseases Laboratories (NEIDL) and the Center for Regenerative Medicine (CReM) joined forces to develop the most relevant research model possible for understanding how the coronavirus virus impacts the lungs, by engineering living, "breathing" human lung cells from stem cells for the task.
In a proof-of-concept study, North Carolina State University researchers reported promising preclinical findings for a prototype of a vascular graft designed as a replacement for a damaged or blocked coronary artery, which supplies blood to the heart.
Science has long known that recovery from experimental heart attacks is improved by injection of a mixture of heart muscle cells, endothelial cells and smooth muscle cells, yet results have been limited by poor engraftment and retention, and researchers worry about potential tumorigenesis and heart arrhythmia.
A veteran's study identified more than a dozen genes associated with abdominal aortic aneurysm (AAA) that could be used to better identify people at risk for the often-deadly condition, according to new research published today in the American Heart Association's flagship journal Circulation.
Today, the U.S. Food and Drug Administration approved Nucala (mepolizumab) for adults and children aged 12 years and older with hypereosinophilic syndrome (HES) for six months or longer without another identifiable non-blood related cause of the disease.
Understanding of fibromuscular dysplasia (FMD), a rare blood vessel disease, is making the jump from the laboratory to the clinic with new findings about a genetic variant.
Researchers at the University of Cincinnati and UC Health will host a Phase 2 clinical trial (NCT04511650) to examine the effects of a drug that targets blood vessel inflammation and injury in patients with COVID-19.
Stroke patients who also have COVID-19 showed increased systemic inflammation, a more serious stroke severity and a much higher rate of death, compared to stroke patients who did not have COVID-19, according to University of Alabama at Birmingham research led by Chen Lin, M.D., an assistant professor in the UAB Department of Neurology.
The high burden of disease caused by the COVID-19 pandemic has led to much research on effective ways to mitigate the health, social, and economic impact of the spread of the infection. A recent study published on the preprint server bioRxiv* in September 2020 reports on the characteristics of the drug baricitinib when used as monotherapy to treat severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Hepatocellular carcinoma is a common liver cancer with poor prognosis. With symptoms not discovered until later stages, it is considered the most fatal malignant liver cancer worldwide.
The Human Molecular Genetics laboratory of the de Duve Institute (UCLouvain), headed by Professor Miikka Vikkula, recently identified mutations in a novel gene, ANGPT2, responsible for primary lymphedema.
Deposits of a protein called "Medin", which manifest in virtually all older adults, reduce the elasticity of blood vessels during aging and hence may be a risk factor for vascular dementia.
Hepatocellular carcinoma is a particularly stubborn form of cancer with few treatments and a high mortality rate.
