Blood Vessel News and Research

RSS

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 insights into devastating second impact syndrome

Physicians at Indiana University School of Medicine and the Northwest Radiology Network (Indianapolis, Indiana) report the case of a 17-year-old high school football player with second impact syndrome (SIS). A rare and devastating traumatic brain injury, SIS occurs when a person, most often a teenager, sustains a second head injury before recovery from an earlier head injury is complete.

Common cholesterol-lowering drug may help protect against cerebral malaria

Researchers have discovered that adding lovastatin, a widely used cholesterol-lowering drug, to traditional antimalarial treatment decreases neuroinflammation and protects against cognitive impairment in a mouse model of cerebral malaria.

Study shows how to prod stem cells to become 2 different types of blood vessel tissues

Growing new blood vessels in the lab is a tough challenge, but a Johns Hopkins engineering team has solved a major stumbling block: how to prod stem cells to become two different types of tissue that are needed to build tiny networks of veins and arteries.

Study identifies mechanisms responsible for regenerating blood vessels in the brain

New research from the University of Georgia identifies the mechanisms responsible for regenerating blood vessels in the brain.

Proteins detected in urine may enable diagnosis of Kawasaki disease

A set of proteins detected in urine by researchers at Boston Children's Hospital may prove to be the first biomarkers for Kawasaki disease, an uncommon but increasingly prevalent disease which causes inflammation of blood vessels that can lead to enlarged coronary arteries and even heart attacks in some children.

Link between silent stroke and Parkinson's disease

Scientists at The University of Manchester have for the first time identified why a patient who appears outwardly healthy may develop Parkinson's disease.

Telestroke networks can improve bottom line of patients and hospitals

Telestroke networks that enable the remote and rapid diagnosis and treatment of stroke can improve the bottom line of patients and hospitals, researchers report.

Blocking single tiny blood vessel in the brain can harm neural tissue and even alter behavior

Blocking a single tiny blood vessel in the brain can harm neural tissue and even alter behavior, a new study from the University of California, San Diego has shown. But these consequences can be mitigated by a drug already in use, suggesting treatment that could slow the progress of dementia associated with cumulative damage to miniscule blood vessels that feed brain cells.

Paroxetine could treat vascular complications of diabetes

University of Texas Medical Branch at Galveston researchers have discovered that the commonly used antidepressant drug paroxetine could also become a therapy for the vascular complications of diabetes.

ETA receptor antagonism reduces novel cardiovascular risk factors in patients with CKD

Blocking the receptor for proteins that constrict blood vessels reduces markers of heart-related problems in patients with chronic kidney disease (CKD), according to a study appearing in an upcoming issue of the Journal of the American Society of Nephrology (JASN).

Arginase, IDO could hold clues to help 79 million Americans with prediabetes

Two enzymes that are elevated in prediabetes could hold clues to helping the 79 million Americans with the condition avoid serious vascular complications and maybe even identify those most at risk for full-blown diabetes, researchers say.

UBC researcher helps create new gel that could glue blood vessels back together

A University of British Columbia researcher has helped create a gel - based on the mussel's knack for clinging to rocks, piers and boat hulls - that can be painted onto the walls of blood vessels and stay put, forming a protective barrier with potentially life-saving implications.

Study reveals dual role for Norrin/Frizzled-4 protein pair

Working with mice, Johns Hopkins researchers have shed light on the activity of a protein pair found in cells that form the walls of blood vessels in the brain and retina, experiments that could lead to therapeutic control of the blood-brain barrier and of blood vessel growth in the eye.

New technique can reduce hemodialysis complications in kidney patients

Approximately two million people around the world regularly undergo hemodialysis - blood purification outside the body - as a result of kidney failure. This usually involves creating a dialysis fistula - a connection between an artery and a vein - in the patient's arm. However this causes complications in as many as 50% of patients, primarily related to changes in blood flow.

Linagliptin may reduce brain damage following stroke in type 2 diabetic patients

In a study in mice, scientists at Karolinska Institutet in Sweden have discovered a new potential therapy that may reduce brain damage following stroke in type 2 diabetic patients. The suggested drug is already approved for the treatment of type 2 diabetes. However, the scientists hope that this new results, presented in the scientific journal Diabetes, also opens up the possibility to decrease brain injury after stroke in other patient groups with a high stroke risk.

Pipeline embolization device shows promise in treating brain aneurysms

A new technology called the Pipeline embolization device (PED) shows encouraging results in patients with certain types of difficult-to-treat brain aneurysms, reports the December issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Diabetes tests: an interview with Dr. Danielle Stowasser

Diabetes is a serious condition that causes high levels of glucose (a type of sugar) in the blood. There are three main types of diabetes: type 1 and type 2 diabetes, which are lifelong conditions, and gestational diabetes, which only occurs in women during pregnancy.

Heart attack centres: an interview with Dr Sayan Sen

Heart attack networks are designed to facilitate the rapid transfer of heart attack patients to centres with facilities that allow the manual unblocking of the coronary artery with angioplasty.

Brain microhemorrhages more common among high altitude cerebral edema survivors

New magnetic resonance imaging (MRI) research shows that mountain climbers who experience a certain type of high altitude sickness have traces of bleeding in the brain years after the initial incident, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).

Arginase might play a role in development of cardiovascular disease in type II diabetics

In a new study published in the scientific journal Circulation, scientists at Karolinska Institutet and Karolinska University Hospital in Sweden show that an enzyme called arginase might have a key part to play in the development of cardiovascular disease in patients who already have type II diabetes.
