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

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.

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.

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.

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.

Study suggests calorie-restricted diet can protect mice from abdominal aortic aneurysms

Mice placed on a low-calorie diet are less likely to develop abdominal aortic aneurysms, according to a new study in The Journal of Experimental Medicine.

Scientists use novel theranostics technique for early thromboembolism diagnosis and treatment

Researchers from the University of Arkansas for Medical Science (USA), in collaboration with University Hospital Frankfurt and University Hospital Dresden, under the supervision of Prof. Vladimir Zharov and with the participation of Alexander Melerzanov, the dean of Department of Biological and Medical Physics (MIPT), conducted experiments on mice to detect blood clotting using photoacoustic flow-cytometry.

Real-time MRI guidance could help target and deliver stem cell therapies

Working with animals, a team of scientists reports it has delivered stem cells to the brain with unprecedented precision by threading a catheter through an artery and infusing the cells under real-time MRI guidance.

New software that simulates interventions could spare young heart patients from surgery

Children with congenital heart defects often undergo a battery of strenuous examinations and interventions. In the EU CARDIOPROOF project, Fraunhofer researchers have developed software to simulate certain interventions in advance.

Good blood microcirculation linked to longevity

Human longevity has been previously linked by researchers to genetic factors, calorie restriction, and certain life-style factors such as physical activity or the Mediterranean diet.

Foul smelling gas could help people with diabetes recover from heart complications

A gas that was formerly known for its noxious qualities could help people with diabetes recover from common heart and blood vessel complications, concludes research led by the University of Exeter Medical School.

Simple steps can improve survival of sepsis patients

Sepsis, commonly called blood poisoning, is a common affliction that can affect people of all ages. A series of simple measures tested at a Norwegian hospital can make a difference in successfully treating sepsis.

Transplantation of placenta-derived MSCs can prevent diabetes-related CLI in rats

In an effort to determine if stem cell therapy can prevent or improve a condition called "diabetic foot" caused by poor blood flow in patients with diabetes, a team of researchers in China has found that transplanting human placenta-derived mesenchymal stem cells (MSCs) into rats modeled with diabetes can affect blood vessel growth, potentially improving blood flow and preventing critical limb ischemia (CLI), a condition that results in diabetic foot and frequently leads to amputation.

Study suggests autologous EPC transfusion may prevent miscarriage in high-risk pregnancies

In a study focusing on the role of self-donated (autologous) bone marrow-derived endothelial progenitor cells (EPCs) in placental vascular development, researchers in Japan have discovered that when transplanted into pregnant mice, EPCs can contribute to better blood vessel growth that helps in forming "normalized" placental vascularization, leading, in turn, to reduced recurrent miscarriages by providing a healthier fetal environment during gestation.

Atomic level analysis reveals how two classes of calcium channel blockers produce different effects

An atomic level analysis has revealed how two classes of calcium channel blockers, widely prescribed for heart disease patients, produce separate therapeutic effects through their actions at different sites on the calcium channel molecule.
