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 develop new, less invasive method to perform TAVR for treating aortic valve stenosis

Researchers develop new, less invasive method to perform TAVR for treating aortic valve stenosis

Researchers at the National Institutes of Health have developed a new, less invasive way to perform transcatheter aortic valve replacement (TAVR), a procedure widely used to treat aortic valve stenosis, a lethal heart condition. [More]
Nano-biointeraction and nanopathology

Nano-biointeraction and nanopathology

Nanoparticles enter the organism in a number of ways. In most cases through inhalation and ingestion. When inhaled, the majority of them are expelled with the next breath. When ingested, most of them are gotten rid of through feces. [More]
Exposure to air pollution may contribute to blood vessel damage among young healthy adults

Exposure to air pollution may contribute to blood vessel damage among young healthy adults

Fine particulate matter air pollution may be associated with blood vessel damage and inflammation among young, healthy adults, according to new research in Circulation Research, an American Heart Association journal. [More]
Research shows metabolism of macrophages can be attuned to prevent spread of cancer

Research shows metabolism of macrophages can be attuned to prevent spread of cancer

Scientists at VIB and KU Leuven have discovered a crucial factor in the spread of cancer. A team led by professor Massimiliano Mazzone has demonstrated that the metabolism of macrophages, a particular type of white blood cell, can be attuned to prevent the spread of cancer. [More]
UC3M scientists use mathematical description to explain how tumors induce growth of blood vessels

UC3M scientists use mathematical description to explain how tumors induce growth of blood vessels

Universidad Carlos III de Madrid has carried out a study that mathematically explains how tumors induce the growth of blood vessels. The study maintains that the tips of the blood vessels expand like a soliton, a solitary wave similar to a tsunami. [More]
Finnish researchers identify molecular mechanism that controls migration of early macrophages

Finnish researchers identify molecular mechanism that controls migration of early macrophages

How could emerging technologies impact cancer care?

How could emerging technologies impact cancer care?

The major innovations in cancer diagnosis, therapy/palliative care and surgical intervention are too numerous to list here. But enormous strides have taken place in stem cell therapy, monoclonal antibody therapy and genetic screening. [More]
Discovery of neuropilin 2 deficiency may lead to new therapies for edema and lymphedema

Discovery of neuropilin 2 deficiency may lead to new therapies for edema and lymphedema

Fluid accumulation and swelling (edema) may result from the malfunctioning of regulatory processes controlling vessel permeability in the body. [More]
Minimally-invasive procedure to fix aortic aneurysm linked to increase in long-term complications

Minimally-invasive procedure to fix aortic aneurysm linked to increase in long-term complications

A minimally-invasive procedure to fix a life-threatening condition may be associated with an increase in long-term complications, compared to an alternative procedure. [More]
Calcium supplements may raise risk of plaque buildup in arteries and heart damage

Calcium supplements may raise risk of plaque buildup in arteries and heart damage

After analyzing 10 years of medical tests on more than 2,700 people in a federally funded heart disease study, researchers at Johns Hopkins Medicine and elsewhere conclude that taking calcium in the form of supplements may raise the risk of plaque buildup in arteries and heart damage, although a diet high in calcium-rich foods appears be protective.

Scientists use 3-D printing to develop customized biodegradable stents

Most people have heard about personalized medicine. But how about personalized medical devices? Northwestern Engineering's Guillermo Ameer and Cheng Sun have teamed up to use 3-D printing to develop flexible, biodegradable stents that are customized for a specific patient's body. [More]
Fighting malaria by altering human flavor

Fighting malaria by altering human flavor

A new study by Johns Hopkins researchers suggests that a specialized area of the mosquito brain mixes tastes with smells to create unique and preferred flavors. The findings advance the possibility, they say, of identifying a substance that makes “human flavor” repulsive to the malaria-bearing species of the mosquitoes, so instead of feasting on us, they keep the disease to themselves, potentially saving an estimated 450,000 lives a year worldwide.

Scientists uncover how microbes invade the brain in bacterial meningitis

Scientists uncover how microbes invade the brain in bacterial meningitis

Simon Fraser University researcher Lisa Craig is part of an international team that has uncovered new details about a microbe that invades the brain, sometimes with fatal results. [More]
Researchers suggest need for human studies to examine effects of cannabinoid use during pregnancy

Researchers suggest need for human studies to examine effects of cannabinoid use during pregnancy

In this new era of legalized marijuana, far too little research has been conducted on the effect of cannabis on the development of human embryos, say researchers at Georgetown University Medical Center who scoured medical literature on the topic and found what they say is worrisome animal research.

Biomedical engineers develop artificial blood vessels capable of growth within recipient

Biomedical engineers develop artificial blood vessels capable of growth within recipient

In a groundbreaking new study led by University of Minnesota biomedical engineers, artificial blood vessels bioengineered in the lab and implanted in young lambs are capable of growth within the recipient. [More]
Interval exercise plans help improve endothelial function in older adults with type 2 diabetes

Interval exercise plans help improve endothelial function in older adults with type 2 diabetes

Resistance-based interval exercise helps improve endothelial function—including blood flow and blood vessel dilation—both in older adults with type 2 diabetes and in age-matched non-exercisers and regular exercisers, according to new research published in the American Journal of Physiology—Heart and Circulatory Physiology.
