Blood Vessels are tubes through which the blood circulates in the body. Blood vessels include a network of arteries, arterioles, capillaries, venules, and veins.

New trial finds signs of preventive cardiovascular effects for cocoa flavanols

The first large-scale trial to test the long-term effects of a cocoa flavanol supplement to prevent cardiovascular disease offers promising signals that cocoa flavanols could have protective cardiovascular effects.

Lower, more frequent doses of nanomedicines may provide additional benefits for cancer patients

Tiny structures called nanoparticles can be used to carry substances to certain parts of the body - for example, to deliver a chemotherapy drug to a tumor.

Blood test shows promise to identify Alzheimer's changes in the brain before symptom onset

The University of Kentucky's Sanders-Brown Center on Aging has been around for nearly half a century. In that time, they have built an international reputation for best-in-class research into a disease that kills more people every year than breast and prostate cancer combined – Alzheimer's disease.

Unusual partners are key to making more blood vessels

Insufficient oxygen to an area like the heart or legs, called hypoxia, is a cue to our bodies to make more blood vessels, and scientists have found some unusual partners are key to making that happen.

A ubiquitous protein may be key to the survival of neurons most impacted by glaucoma

A ubiquitous protein called sigma 1 receptor, which is known to protect cells from stress, appears key to the function and survival of the neurons most impacted by glaucoma, scientists report.

Doing less exercise could deactivate a vital protein in the body, suggests study

Doing less exercise could deactivate a vital protein in the body, causing further inactivity and making exercise more difficult, new research suggests.

New imaging approach provides a clearer ‘picture’ of blood vessels in health and disease

Johns Hopkins Medicine researchers have developed and tested a new imaging approach they say will accelerate imaging-based research in the lab by allowing investigators to capture images of blood vessels at different spatial scales.

Study reveals mechanisms associated with severe blood clotting in COVID-19 patients

After studying blood samples from 244 patients hospitalized for COVID-19, a group of researchers, including those who work at the National Institutes of Health, identified “rogue antibodies” that correlate with severe illness and may help explain mechanisms associated with severe blood clotting.

Study shows the true prevalence of statin intolerance worldwide is between 6 to 10%

As many as one in two patients stop taking statins, reduce the dose or take them irregularly because they believe the cholesterol-lowering drugs cause muscle pain and other side-effects.

Researchers create a comprehensive atlas of cerebrovascular cell types

While neurons and glial cells are by far the most numerous cells in the brain, many other types of cells play important roles. Among those are cerebrovascular cells, which form the blood vessels that deliver oxygen and other nutrients to the brain.

Studies compare endovascular therapy and microsurgery for treating wide-neck aneurysms

Aneurysms are weak, bulging portions of blood vessel walls. These blood-filled sacs resemble balloons in structure and have necks like balloons. Some aneurysms have larger necks and are called "wide-neck" aneurysms.

Structural protein vimentin facilitates SARS-CoV-2 entry into endothelial cells

Researchers suggest that extracellular vimentin may act as a coreceptor to allow for SARS-CoV-2 entry into cells.

New system enables automatic analysis of biomedical videos captured by microscopy

Researchers at the Universidad Carlos III de Madrid have developed a system based on computer vision techniques that allows automatic analysis of biomedical videos captured by microscopy in order to characterize and describe the behavior of the cells that appear in the images.

Mechanical clot removal may improve recovery after severe stroke in children

Serious disability was 6 times more likely to be the result three months after stroke among children whose clot-caused stroke in a large vessel (a type of ischemic stroke) was not treated with a procedure to extract the clot, according to preliminary late-breaking science presented today at the American Stroke Association's International Stroke Conference 2022.

Stroke patients have higher chance of better outcomes when treated at Comprehensive Stroke Centers

When comparing outcomes for acute ischemic stroke patients treated at various levels of stroke centers, patients who received care at Comprehensive Stroke Centers (CSC) or Thrombectomy-capable Stroke Centers (TSC) were more likely to receive rapid treatment with clot-busting medication and/or mechanical clot removal and be discharged home or to rehabilitation centers than patients treated at Primary Stroke Centers, according to preliminary research to be presented today at the American Stroke Association's International Stroke Conference 2022.

Mechanical blood clot removal helps nearly half of stroke survivors to achieve good outcomes

Mechanical removal of blood clots reduced post-stroke disability in nearly half of "all-comer" real-world stroke patients in an international study, according to preliminary late-breaking science presented today at the American Stroke Association's International Stroke Conference 2022.

Cognitive impairment in patients with long-COVID can be improved using brain stimulation

Many recovered COVID-19 patients continue to exhibit significant and long-lasting cognitive deficits in memory, attention, language comprehension and multitasking, as well as fatigue.

Developing injectable granular hydrogels for brain regeneration and function recovery after stroke

The Centers for Disease Control and Prevention estimate that someone in the United States has a stroke every 40 seconds.

A theoretical model may help better understand how blood circulates in the brain

Research carried out by the Universidad Carlos III de Madrid (UC3M) may help us better understand oscillations in blood flow that occur in the cerebrovascular network, thanks to a theoretical model that allows the flow and accumulation of fluid (in this case, blood) to be taken into account.

Older adults have greatest stroke risk in the first three days after COVID-19 diagnosis

The risk of stroke among older adults diagnosed with COVID-19 was highest within the first three days of diagnosis, according to preliminary research to be presented at the American Stroke Association's International Stroke Conference 2022, a world premier meeting for researchers and clinicians dedicated to the science of stroke and brain health to be held in person in New Orleans and virtually, Feb. 8-11, 2022.
