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

Researchers investigate role of microRNAs in breast cancer cells

Metastasis — the spreading of cancer cells from a primary tumor site to other parts of the body — generally leads to poorer outcomes for patients, so oncologists and researchers are constantly seeking new ways to detect and thwart this malicious process. [More]

Study describes how overeating causes brown fat cells to "whiten"

Boston University researchers have learned new information about the consequences of overeating high-calorie foods. Not only does this lead to an increase in white fat cell production, the type prominent in obesity, but it also leads to the dysfunction of brown fat cells, the unique type of fat that generates heat and burns energy.

Stem cells culled from bone marrow may prove beneficial in stroke recovery

Stem cells culled from bone marrow may prove beneficial in stroke recovery, scientists at UC Irvine's Sue & Bill Gross Stem Cell Research Center have learned. [More]

Scientists working on new blood test to diagnose stroke faster

When someone suffers from a stroke, a silent countdown begins. A fast diagnosis and treatment can mean the difference between life and death. So scientists are working on a new blood test that one day could rapidly confirm whether someone is having a stroke and what kind. Their report appears in the ACS journal Analytical Chemistry.

Patient-friendly examination method reduces need for prostate cancer biopsies

Each year prostate tissue samples are taken from over a million men around the world - in most cases using 12 large biopsy needles - to check whether they have prostate cancer. [More]

Heparin proves effective than bivalirudin in patients receiving percutaneous coronary intervention after heart attack

Heparin proves effective than bivalirudin in patients receiving percutaneous coronary intervention after heart attack

In a comparison of two blood-thinning medications, heparin was associated with significantly fewer major cardiovascular events at 28 days than bivalirudin in patients receiving primary percutaneous coronary intervention after a heart attack, according to research presented at the American College of Cardiology's 63rd Annual Scientific Session.

Heart problems less likely for spouses than for single people

Heart problems less likely for spouses than for single people

People who are married have lower rates of several cardiovascular diseases compared with those who are single, divorced or widowed, according to research to be presented at the American College of Cardiology's 63rd Annual Scientific Session. The relationship between marriage and lower odds of vascular diseases is especially pronounced before age 50. [More]
BIDMC scientist wins Gairdner Award for landmark discovery in the field of angiogenesis

BIDMC scientist wins Gairdner Award for landmark discovery in the field of angiogenesis

Harold F. Dvorak, MD, senior investigator in the Center for Vascular Biology Research at Beth Israel Deaconess Medical Center and former chairman of BIDMC's Department of Pathology, is one of eight scientists to win the 2014 Canada Gairdner Awards, which recognize some of the most significant medical discoveries from around the world. Awarded by the Gairdner Foundation, based in Canada, the awards are considered among the most prestigious international awards in medical research. [More]

Research provides first evidence to help prevent certain stroke patients

Neurologists have long debated how to help prevent certain stroke patients from suffering a second stroke. Now research from UNC School of Medicine provides the first evidence for which course of treatment is truly best for patients with poor collateral blood vessel formation near the site of stroke: they should have their blood pressure lowered to normal levels.

Research may lead the way toward new treatments for proliferative retinopathies

Research may lead the way toward new treatments for proliferative retinopathies

A new report published online in The FASEB Journal may lead the way toward new treatments or a cure for a common cause of blindness (proliferative retinopathies). Specifically, scientists have discovered that the body's innate immune system does more than help ward off external pathogens. [More]

Endogenous tissue growth: an interview with Laurent Grandidier, CEO, Xeltis

ETG or Endogenous Tissue Growth is a new therapeutic category in which surgeons use implants designed to allow the body to repair itself by spontaneously growing natural, healthy tissue from the inside without the use of stem cells or animal-derived products. [More]
Protein known to promote cancer appears to give blood vessels strength and shape, researchers report

Protein known to promote cancer appears to give blood vessels strength and shape, researchers report

A protein known to promote cancer appears to give the blood vessels strength and shape, researchers report. When yes-associated protein, or YAP, is deleted from vascular smooth muscle cells during development, the protein makes thin-walled blood vessels that over-dilate in response to the usual pressure of blood flow, said Dr. Jiliang Zhou, vascular biologist at the Medical College of Georgia at Georgia Regents University.

The presence of lymphatic invasion indicates a worse prognosis for patients with pathologically node-positive lung adenocarcinoma, compared with its absence, indicate Japanese study findings. [More]
Researchers identify two novel genes associated with development of rare, aggressive blood cancer

Researchers identify two novel genes associated with development of rare, aggressive blood cancer

R​esearchers have identified two novel cancer genes that are associated with the development of a rare, highly aggressive, cancer of blood vessels. These genes may now act as markers for future treatments and explain why narrowly targeted therapies that are directed at just one target fail. [More]
Exposure to UV light may exacerbate melanoma cells to creep outside blood vessels

Exposure to UV light may exacerbate melanoma cells to creep outside blood vessels

Based on the pioneering work of Dr. Claire Lugassy and Dr. Raymond Barnhill at UCLA's Jonsson Comprehensive Cancer Center, a new study provides additional support for a process by which melanoma cells, a deadly form of skin cancer, can spread throughout the body by creeping like tiny spiders along the outside of blood vessels without ever entering the blood stream, and that this process is exacerbated by exposure to ultraviolet (UV) light.
