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

Routine eye imaging may provide clues to cognitive disorders in older people with type 1 diabetes

As they age, people with diabetes are more likely to develop Alzheimer's disease and other cognitive disorders than are people without diabetes.

Scientists discover cell responsible for triggering chronic, low-level inflammation in fat tissue

When fat cells in the body are stuffed with excess fat, the surrounding tissue becomes inflamed. That chronic, low-level inflammation is one of the driving factors behind many of the diseases associated with obesity.

Brain damage is not caused by direct COVID-19 attack, indicates study

n an in-depth study of how COVID-19 affects a patient's brain, National Institutes of Health researchers consistently spotted hallmarks of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly after contracting the disease.

The evolving role of platelet-rich plasma in cosmetic procedures

Platelet-rich plasma (PRP) treatment, which involves injecting a small amount of a patient's own blood to release various growth factors from platelets, continues to increase in popularity.

FDA authorizes first device to treat patients with walled-off pancreatic necrosis

Today, the U.S. Food and Drug Administration authorized marketing of the EndoRotor System to resect (cut out) and remove necrotic (dead) tissue for patients with walled-off pancreatic necrosis (WOPN), a potentially deadly condition which can occur several weeks after an episode of severe acute pancreatitis, often requiring tissue removal.

Researchers uncover key regulation step that inhibits tumor growth

Most living things need oxygen to grow and thrive. Even cancerous tumors. That's why tumors will readily sprout new blood vessels if their oxygen is starved, creating new lifelines for survival.

Novel tantalum-loaded hydrogel for rapid control of excessive bleeding

There are many different events which may lead to excessive and uncontrolled bleeding within the body. This can occur as a result of inflammation and ulcerations, abnormalities in the blood vessels or trauma-related injuries.

Researchers identify novel mechanism by which CREB3L3 protein protects against atherosclerosis

Researchers from the University of Tsukuba identify a novel mechanism by which the protein CREB3L3 protects against atherosclerosis.

Study may help explain how COVID-19 increases stroke risk

A UCLA-led study may help explain how COVID-19 increases the risk for stroke. Scientists made the finding by running fluid spiked with a COVID-19-like protein through a 3D-printed model of the arteries of a patient who had suffered a stroke.

Penn State engineers find link between nitric oxide expressing neurons and arterial dilation

Neurons control blood flow in tiny vessels in the brain, but researchers know little about this relationship.

Impaired blood vessel and kidney function underlie heart disease risk in people with HIV

A new study has found impaired blood vessel function in those living with human immunodeficiency virus (HIV).

Surgical and drug treatment approaches are equally effective for diabetic eye disease

Surgical and injectable drug approaches are equally effective for treatment of bleeding inside the eye from proliferative diabetic retinopathy (PDR), according to a National Eye Institute (NEI)-supported clinical study from the DRCR Retina Network (DRCR.net).

Detailed simulations reveal new information on sickle cell disease

Although there has yet to be a cure for sickle cell disease, researchers recently created detailed simulations on the Comet system at the San Diego Supercomputer Center (SDSC) showing how these stiff red blood cells flow through blood vessels, deforming and colliding along the way.

Study: Paclitaxel-coated devices do not increase mortality for patients with peripheral artery disease

An interim analysis from the Swedish Drug-Elution Trial in Peripheral Arterial Disease (SWEDEPAD) has now been presented.

Researchers find elevated biomarker for blood vessel damage in children with SARS-CoV-2

Researchers at Children's Hospital of Philadelphia have found elevated levels of a biomarker related to blood vessel damage in children with SARS-CoV-2 infection, even if the children had minimal or no symptoms of COVID-19.

Study reveals genetic abnormalities that cause brain aneurysms

Nearly three percent of the world's population is at risk of developing an intracranial aneurysm, a localized dilation of a blood vessel forming a fragile pocket. Rupture of this aneurysm results in extremely severe, and, in one-third of cases, fatal hemorrhage.

Findings about primary cilia may be relevant for transplantation therapies in diabetes

A new study from Karolinska Institutet and the Helmholtz Diabetes Research Center shows that primary cilia, hair-like protrusions on endothelial cells inside vessels, play an important role in the blood supply and delivery of glucose to the insulin-producing beta cells in the pancreatic islets.
