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

Study explains indirect burden of malaria on childhood deaths

Recurrent episodes of malaria cause chronic inflammation in blood vessels that might predispose to future infections and may increase susceptibility to cardiovascular disease, a Wellcome Trust study in Malawian children finds.

New optical imaging tool enables scientists to observe tumors and uncover inner workings

Scientists seeking new ways to fight cancer often try to understand the subtle, often invisible, changes to DNA, proteins, cells, and tissue that alter the body's normal biology and cause disease.

Researchers develop synthetic peptide that could be a new class of drugs for heart disease

Researchers at the University of Alberta have developed a synthetic peptide that could be the first in a new class of drugs to treat heart disease, high blood pressure and diabetes.

Researchers develop new ways of preventing septic shock

The body's immune system is set up much like a home security system; it has sensors on the outside of cells that act like motion detectors — floodlights — that click on when there's an intruder rustling in the bushes, bacteria that seem suspect.

Simple method helps identify individuals who retain too much sodium

Getting a second urine sample and blood pressure measure as patients head out of the doctor's office appears an efficient way to identify those whose health may be in jeopardy because their bodies hold onto too much sodium, researchers report.

Elevated miR-200 boosts survival of lung, ovarian, renal, triple-negative breast cancer patients

A family of microRNAs (miR-200) blocks cancer progression and metastasis by stifling a tumor's ability to weave new blood vessels to support itself, researchers at The University of Texas MD Anderson Cancer Center report today in Nature Communications.

TSRI scientists identify involvement of angiomotin protein in cancer

A team led by scientists from The Scripps Research Institute have shown that a protein once thought to inhibit the growth of tumors is instead required for initial tumor growth.

Experimental agent fails to increase HDL levels, reveals new study

The search continues for an agent that increases high-density lipoprotein (HDL) and reduces arterial plaque, after the experimental apolipoprotein A1 (apoA1) inducer, RVX-208 failed to do so in the ApoA1 Synthesis Stimulation and Intravascular Ultrasound for Coronary Atheroma Regression Evaluation (ASSURE) study.

TSRI scientists discover isoform of angiomotin protein responsible for tumorigenesis

A team led by scientists from The Scripps Research Institute (TSRI) have shown that a protein once thought to inhibit the growth of tumors is instead required for initial tumor growth. The findings could point to a new approach to cancer treatment.

Case Western researchers establish Kruppel-like factors as master regulators of vascular health

Case Western Reserve researchers have identified a genetic factor that blocks the blood vessel inflammation that can lead to heart attacks, strokes and other potentially life-threatening events.

Obese people with high insulin levels likely to experience better blood vessel function following weight loss

Researchers from Boston University School of Medicine (BUSM) and Boston Medical Center (BMC) have found that among obese people who had lost considerable weight, those with high insulin levels--a marker of insulin resistance in the body--were the most likely to experience better blood vessel function following the weight loss. These findings appear online in the Journal of the American College of Cardiology.

Findings could alter ways in which doctors use platelets to treat traumatic injuries

A new finding could lead to novel treatments to reduce bleeding in trauma and severe infections.

Protein activated by inflammation converts glioblastoma multiforme cells to most aggressive form

A prominent protein activated by inflammation is the key instigator that converts glioblastoma multiforme cells to their most aggressive, untreatable form and promotes resistance to radiation therapy, an international team lead by researchers at The University of Texas MD Anderson Cancer Center reported online today in the journal Cancer Cell.

Study reveals zinc-regulated small compound in blood mediates harmful effects of zinc deprivation

According to new research published in The FASEB Journal, a drop in blood zinc levels does not directly harm the blood vessel cells. Rather, zinc regulates the production of a small molecular compound, which then circulates in the blood and causes harmful blood vessel cell effects.

WPI researchers receive NIH grant to develop cell therapies for healing cardiac muscle

The National Institutes of Health (NIH) has awarded a five-year, $1.94 million grant to a biomedical research team at Worcester Polytechnic Institute (WPI) working at the forefront of cell therapies for healing cardiac muscle damaged by heart attack or chronic disease.

Study reports racial, ethnic differences in incidence of soft tissue sarcomas in young adults, adolescents

Mei-Chin Hsieh, MSPH, CTR, of LSU Health Sciences Center New Orleans School of Public Health's Louisiana Tumor Registry, is the lead author of a study that reports racial and ethnic differences in the incidence of soft tissue sarcomas in adolescents and young adults.

Scientists grow cells that line blood vessels from human iPSCs

In a scientific first, Harvard Stem Cell Institute scientists have successfully grown the cells that line the blood vessels-called vascular endothelial cells-from human induced pluripotent stem cells (iPSCs), revealing new details about how these cells function.

New drug-delivery strategy for central vision loss

Johns Hopkins biomedical engineers have teamed up with clinicians to create a new drug-delivery strategy for a type of central vision loss caused by blood vessel growth at the back of the eye, where such growth should not occur.

Researchers find recurrent genetic mutation linked to deadly thoracic aortic dissections

A multi-institutional team led by Dianna Milewicz, M.D., Ph.D., of The University of Texas Health Science Center at Houston (UTHealth) has found a recurrent genetic mutation that has been linked to deadly thoracic aortic dissections in family members as young as 17 years of age.

Drug-related emergency department visits increase among younger adults

A new report by the Substance Abuse and Mental Health Services Administration shows that some drug-related emergency department visits increased by 300 percent -- from 5,605 visits in 2005 to 22,949 visits in 2011. These visits, made by adults aged 18 to 34, were related to the nonmedical use of central nervous system stimulants. On average, about 30 percent of these visits also involved alcohol.
