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 a study of eye fluid from 38 patients, Johns Hopkins Medicine researchers say they have found that levels of a specific protein appears to help accurately predict whether people with the wet form of age-related macular degeneration may need lifelong, frequent eye injections to preserve vision or if they can be safely weaned off the treatments.
Millions of children in low- and middle-income nations suffer from environmental enteric dysfunction (EED), a chronic inflammatory disease of the intestine that is the second leading cause of death in children under five years old.
Before a baby is ever born, critical supply chain problems with nutrition and oxygen can result in premature birth or even death and increase the child and mother's lifelong risk of cardiovascular disease.
E-cigarettes have become increasingly popular among adolescents, and the latest available scientific evidence suggests the use of these products has adverse health effects that may accrue over time, leading to an increased risk of cardiovascular and pulmonary disease over the course of the life of people who use e-cigarettes, according to a new scientific statement from the American Heart Association published today in the Association's peer-reviewed journal, Circulation: Research.
Blood vessels must adapt their growth to the nutrients available in their surroundings so that they can keep organs adequately supplied. A team led by Michael Potente has identified two proteins that are important for this process and published their findings in Nature Metabolism.
Scientists at the University of Illinois Chicago have analyzed gene expression data from more than 35,000 blood vessel cells from the lungs of mice and identified two subtypes.
A team of researchers led by Dr. Sandra Castillo and Dr. Mariona Graupera, from the Josep Carreras Leukaemia Research Institute and member of the CIBERONC, have found the AKT inhibitor miransertib could be a new molecular treatment effective against low-flow vascular malformations, a long-awaited milestone.
With prompt diagnosis and the right treatment, people with HIV can live long, healthy lives. In recent years, however, gains in survival among people with HIV have exposed a new concern – an increase in the incidence of early-onset cardiovascular disease associated with long-term HIV.
A new American Heart Association scientific statement highlights the need for more data and research about sex differences in the use and response to mechanical clot removal for acute ischemic stroke and suggests a clear differentiation between sex and gender in future research.
Middle-aged women with higher blood concentrations of common synthetic chemicals called per- and polyfluoroalkyl substances (PFAS), also called "forever chemicals" and found in water, soil, air and food, were at greater risk of developing high blood pressure, compared to their peers who had lower levels of these substances, according to new research published today in Hypertension, an American Heart Association journal.
A stress protein that is overactive in many types of tumor cells also has a key role in tumor-supporting cells called fibroblasts, and may be a good target for future cancer treatments, suggests a study from researchers at the Perelman School of Medicine at the University of Pennsylvania.
The same properties that caused birth defects when it was given to pregnant women, the inhibition of blood vessel formation (anti-angiogenesis), have led to an interest in thalidomide's therapeutic utility in other fields.
Each year, dentists in the United States perform more than 15 million root canals on infected teeth, removing the inflamed pulp and filling the emptied canal with inert materials such as rubber and cement. What remains is a mineral shell in place of a living tooth.
A molecule in mosquito spit has been identified as a potential new target for vaccination against a range of diseases for which there is no protection or medicine.
A blood clot in the brain that blocks the supply of oxygen can cause an acute stroke. In this case, every minute counts.
The National Institute on Aging, a division of the National Institutes of Health, awarded Berislav Zlokovic, MD, PhD, director of the Zilkha Neurogenetic Institute, and Arthur W. Toga, PhD, director of the USC Mark and Mary Stevens Neuroimaging and Informatics Institute (Stevens INI), $16.1 million to continue research on the role that blood vessel dysfunction plays in the development of dementia and Alzheimer's disease.
Sepsis, the body's overreaction to an infection, affects more than 1.5 million people and kills at least 270,000 every year in the U.S. alone.
The lack of diversity in genomic research could mean Africans are missing out on potential life-changing care for chronic health disorders, according to a new study published in Nature Medicine.
For more than 20 years, scientists have known that people with hypertension, diabetes, high cholesterol, or obesity have a higher likelihood of developing Alzheimer's disease.
Patients with non-alcoholic fatty liver disease (NAFLD) are at higher risk of cardiovascular disease, because NAFLD prompts the over-production of a class of proteins that cause inflammation and damage to their blood vessels.
