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 promise of new treatments for sickle cell disease, a group of inherited red blood cell disorders, has never been so great, but it will only be realized if there is constant investment in health policies such as programs for screening newborns, especially in sub-Saharan Africa, where most cases occur.
Mortality due to prostate cancer is usually related to its likelihood to metastasize, especially to bone. Prognostic biomarkers are urgently needed to predict disease aggression so that appropriate treatment can be selected.
Researchers at the University of Illinois at Chicago describe for the first time the role of a unique, pressure-sensing protein in the development of lung edema -- a condition in which chronic high vascular pressure in the lungs causes fluid from the bloodstream to enter the air spaces of the lungs.
A common genetic deficiency empowers glioblastoma to broadcast a molecular message to the wrong type of immune cell, summoning macrophages that protect and nurture the brain tumor instead of attacking it, researchers at The University of Texas MD Anderson Cancer Center report in Cancer Cell.
Effective antiretroviral therapy has changed the human immunodeficiency virus (HIV) from a progressive, fatal disease to a chronic, manageable condition that is associated with higher rates of heart attacks, strokes, heart failure, sudden cardiac deaths, and other diseases compared to people without HIV, according to a new scientific statement from the American Heart Association published in the Association journal Circulation.
Scientists from The University of Queensland's Diamantina Institute have revealed the difference between a stem cell and other blood vessel cells using gene-sequencing technology.
Researchers have discovered a new genetic variant responsible for blood vessel dysregulation in the development of age-related macular degeneration (AMD).
Atherosclerosis is a common, potentially serious condition caused by a build-up of fatty material in the lining of the artery walls. It can lead to coronary artery disease, stroke or kidney problems, and existing treatments tend to be only short-term fixes.
An important class of drug used to treat cancer patients could be used to treat brain aneurysms, according to new research published this week.
Although the occurrence of first-ever ischemic stroke (strokes due to a blood clot that blocks a blood vessel in the brain) at middle age has been decreasing over time, researchers have found that the decline is not as steep as seen in older adults.
A study conducted by an international group of researchers has overturned the understanding of life-threatening inflammatory diseases such as sepsis, pointing to a biochemical agent that may be involved in the rapid decline in blood pressure that occurs in the advanced stage of sepsis and usually causes the patient's death. This discovery could pave the way for novel therapeutic approaches.
Preliminary laboratory tests show that functionalized magnetic beads successfully reduced blood levels of a harmful molecule that is elevated during preeclampsia, according to new research in the American Heart Association's journal Hypertension.
Age-related macular degeneration is one of the most common causes of vision loss in people over age 65.
A stroke treatment developed by researcher Byron Ford at the University of California, Riverside, has moved toward clinical trials.
Long-term stress has been linked with cardiovascular disease, but for people with depression, researchers say small, everyday stressors may be enough to diminish blood vessel function in otherwise healthy adults.
Johns Hopkins Medicine researchers say they have developed something akin to a “Google Maps” approach for more accurately computing and visualizing the structural and functional blood vessel changes needed for tumor growth.
The future of medicine is biological - and scientists hope we will soon be using 3D-printed biologically functional tissue to replace irreparably damaged tissue in the body.
A team of plastic surgeons and material scientists has made an important advance in treating the common clinical problem of soft tissue loss.
Coronary artery bypass grafting surgery may be the best treatment option for most patients with more than one blocked heart artery, according to research published today in The Annals of Thoracic Surgery, published by Elsevier.
A research team led by investigators at Massachusetts General Hospital and the Massachusetts Institute of Technology has found that combining a specialized version of an antihypertension drug with immune checkpoint blockers could increase the effectiveness of cancer immunotherapies.
