Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.
The majority of heart attacks and strokes in the world are ischemic, meaning a clot or buildup of plaque in an artery prevents oxygen-rich blood from reaching cells in the heart or brain. Blocked for too long, tissues die.
In case of heart and/or lung failure, an ECMO machine can be used to maintain organ function for days or even weeks.
Networks adapt over time and in this way form a kind of memory. This is the key finding of a new study by researchers from the Max Planck Institute for Dynamics and Self-Organization in Göttingen and the Technical University of Munich.
Using skin biopsy samples, investigators found that patients with severe COVID-19 had clots in small venous and arterial blood vessels in skin that appears normal.
Children born to mothers with polycystic ovary syndrome (PCOS) have an increased risk of developing infections, allergies and other childhood illnesses by the age of 13, according to the largest study to investigate this.
Medicinal microrobots could help physicians better treat and prevent diseases. But most of these devices are made with synthetic materials that trigger immune responses in vivo.
PASC is likely the result of long-term persistence of SARS-CoV-2 in various tissues
In a review of published research papers, investigators from the Johns Hopkins Medicine Hereditary Hemorrhagic Telangiectasia Center have identified a substantial lack of racial and ethnic data that may be negatively impacting the treatment and diagnosis of this rare disorder in diverse patients.
People who add extra salt to their food at the table are at higher risk of dying prematurely from any cause, according to a study of more than 500,000 people, published in the European Heart Journal today (Monday).
The formation of new blood vessels, also known as angiogenesis, is critical to the development and progression of cancer.
Smoking traditional or non-combustible cigarettes while wearing a surgical mask results in a two-fold rise in exhaled carbon monoxide and impaired blood vessel function compared to non-mask periods.
A new study discusses some of the key functions of myostatin in female reproductive health and disease.
A study from the National Institutes of Health describes the immune response triggered by COVID-19 infection that damages the brain's blood vessels and may lead to short- and long-term neurological symptoms.
A team of clinician-scientists and scientists, led by the National Cancer Centre Singapore and A*STAR's Genome Institute of Singapore together with collaborators in Europe and South Korea, used single-cell techniques to uncover a central dichotomy for colorectal cancer cells, leading to a proposed update of the classification system for the disease.
New research from RCSI University of Medicine and Health Sciences has found that high levels in the bloodstream of a key protein involved in blood clotting called von Willebrand Factor, can lead to poorer outcomes for breast cancer patients.
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.
