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 common inflammatory condition sinusitis is linked to a 40% heightened risk of a subsequent diagnosis of rheumatic disease, particularly in the 5 to 10 years preceding the start of symptoms, finds research published in the open access journal RMD Open.
Blood vessels that cross-connect adjacent arterial trees regulate blood flow to the brain in stroke patients.
A large-scale clinical trial of treatment strategies for Crohn's disease has shown that offering early advanced therapy to all patients straight after diagnosis can drastically improve outcomes, including by reducing the number of people requiring urgent abdominal surgery for treatment of their disease by ten-fold.
Today, a team of scientists from Trinity College Dublin and investigators from FutureNeuro announced a major discovery that has profound importance for our understanding of brain fog and cognitive decline seen in some patients with Long COVID.
Over 100,000 individuals in the United States are currently in need of organ transplants. The demand for organs, such as hearts, kidneys, and livers, far exceeds the available supply and people sometimes wait years to receive a donated organ.
Injection of a substance to block an artery feeding the dura (protective sack around the brain) along with surgery to remove pooled blood reduced the risk that patients will require repeat surgery compared to surgical drainage alone, according to preliminary late-breaking science presented today at the American Stroke Association's International Stroke Conference 2024.
Mount Sinai researchers have shown for the first time that immune cells called monocytes, derived in the bone marrow and released into the bloodstream, can be drawn during stress into sites in the brain that control emotional behaviors.
In a recent study of the brain's waste drainage system, researchers from Washington University in St. Louis, collaborating with investigators at the National Institute of Neurological Disorders and Stroke (NINDS), a part of the National Institute of Health (NIH), discovered a direct connection between the brain and its tough protective covering, the dura mater.
Researchers from Queen Mary University of London have found that the molecule RvT4 enhances the body's natural defences against atherosclerosis (hardening of the arteries) in patients with rheumatoid arthritis.
A Doppler ultrasound that measures the blood flow of small unborn babies can reveal whether or not the placenta is working properly. In case of repeated deviations from these Doppler measurements, additional monitoring of the unborn baby is necessary.
Scientists from the German Cancer Research Center (DKFZ) and Heidelberg University investigated in mice how spreading tumor cells behave at the site of metastasis: Some tumor cells immediately start to form metastases.
Some hereditary genetic defects cause an exaggerated immune response that can be fatal. Using the CRISPR-Cas9 gene-editing tool, such defects can be corrected, thus normalizing the immune response, as researchers led by Klaus Rajewsky from the Max Delbrück Center now report in "Science Immunology."
New findings in The American Journal of Pathology, published by Elsevier, report that a class of small RNAs (microRNAs), microRNA-29, can restore normal skin structure rather than producing a wound closure by a connective tissue (scar).
Chocolate valentines and candies with sweet sayings shouldn't be the only hearts you think about this February.
Unexplained rapid weight loss in older people could be a sign of underlying disease and can be linked with increased risk of falls and fractures, as well as a poorer long-term prognosis.
A recent scientific statement from the American Heart Association suggests that resistance training is at least as safe as aerobic exercise for those with heart disease and other health conditions, and for most people can provide similar or additive benefits in lowering risk factors for cardiovascular disease.
A new scientific statement from the American Heart Association emphasizes the need to increase patients' and physicians' awareness of cerebral venous thrombosis (CVT) to improve the recognition of this condition and initiate prompt medical treatment.
A groundbreaking technology with immense potential in treating ischemic retinopathy in premature infants and diabetic patients has been developed by Professor Byoung Heon Kang and his research team in the Department of Biological Sciences at UNIST, in collaboration with Professor Dong Ho Park's team at Kyungpook National University Hospital. Ischemic retinopathy, characterized by the breakdown of the blood-retinal barrier and abnormal blood vessel growth, often leads to vision impairment and loss.
An international research team led by Tell Bennett, MD, MS, professor of biomedical informatics and pediatric critical care at the University of Colorado School of Medicine, released new diagnostic criteria for sepsis in children this week, marking the first update to the pediatric sepsis definition in nearly two decades.
