Humans not as exceptional in using brain power as we like to think

For years, scientists assumed that humans devote a larger share of their daily calories to their brains than other animals. Although the human brain makes up only 2 percent of body weight, it consumes more than 25 percent of our baseline energy budget.

First-of-its-kind nonsynthetic, decellularized graft one step closer to clinical trials

Researchers at the University of Minnesota have created a new lab-grown blood vessel replacement that is composed completely of biological materials, but surprisingly doesn't contain any living cells at implantation. The vessel, that could be used as an "off the shelf" graft for kidney dialysis patients, performed well in a recent study with nonhuman primates.

Short-term exposure to western diet can put individuals at risk for vascular damage and prediabetes

Could short-term exposure to the average American diet increase one’s risk for developing diabetes and cardiovascular disease? According to a recent study funded by the American Heart Association (AHA), researchers from New York Institute of Technology College of Osteopathic Medicine (NYITCOM) provide compelling evidence to support this hypothesis.

Research may explain why gum disease is linked to heart problems

Heart disease and fatty clogs in the arteries go hand in hand. But new evidence suggests the fatty molecules might come not only from what you eat, but from the bacteria in your mouth, report UConn scientists in the 16 August issue of the Journal of Lipid Research.

Studies identify key characteristics that may allow some obese people to have 'healthier' fat tissue

One little understood paradox in the study of obesity is that overweight people who break down fat at a high rate are less healthy than peers who store their fat more effectively.

Study: Brazilian native fruit trees have powerful anti-oxidant , anti-inflammatory properties

According to a study supported by the São Paulo Research Foundation five fruit trees native to the Atlantic Rainforest have powerful anti-oxidant and anti-inflammatory properties.

Low-cost upgrade of 2D ultrasound machines into 3D imaging devices

Technology that keeps track of how your smartphone is oriented can now give $50,000 ultrasound machines many of the 3-D imaging abilities of their $250,000 counterparts -- for the cost of a $10 microchip.

Alzheimer's disease could be triggered by breakdowns from other parts of the body

Alzheimer's disease, the leading cause of dementia, has long been assumed to originate in the brain. But research from the University of British Columbia and Chinese scientists indicates that it could be triggered by breakdowns elsewhere in the body.

New biomarkers could help doctors diagnose traumatic brain injury through simple blood test

UCLA researchers have identified four biomarkers that could help doctors diagnose brain trauma and concussions through a simple blood test. The biomarkers are proteins, from brain cells called astrocytes, which are released instantly into the bloodstream when astrocytes' outer membranes rupture from blunt impact or whiplash trauma.

Researchers identify link between circadian rhythm disturbance and brain dysfunction

Researchers at Okayama University describe in the Journal of Neuroscience that a certain protein known to play a major role in circadian rhythmicity — humans’ intrinsic 24-hour biological cycle — is also key to proper brain functioning.

Losing weight with diet, physical activity can improve blood flow in the brain of older adults with diabetes

Type 2 diabetes affects blood circulation. The disease stiffens blood vessels and reduces the amount of oxygen that circulates throughout your body. This includes your brain. When blood flow in the brain is impaired, it can affect the way we think and make decisions.

Study demonstrates beneficial effects of calorie-restricted diet in mice

Caloric restriction diets have been associated with various health benefits, but their effects on the skin have not been previously demonstrated. Research conducted at the University of São Paulo (USP) in Brazil shows that controlling calories helps mice live longer, although it reduces the reserves of fat in adipose tissue needed to keep the body warm.

Newly identified microRNA impedes malignancy of tumor cells and metastasis

Cancer cells can reactivate a cellular process that is an essential part of embryonic development. This allows them to leave the primary tumor, penetrate the surrounding tissue and form metastases in peripheral organs.

New research may protect Navy divers from oxygen toxicity in the deep

Special Operations divers like Navy SEALs take on life-threatening risks such as enemy combatants and harsh environments. But another hazard is silent and unseen -- oxygen toxicity, the result of breathing lethal levels of oxygen that occur at depth and pressure.

UC San Diego scientists unravel how ‘resting-state connectivity’ occurs in the brain

Scientists have known that areas of the brain with similar functions--even those in different brain hemispheres--connect to share signals when the body rests, but they haven't known how this "resting-state connectivity" occurs.

Direct application of immune cells accelerates healing of acute, chronic wounds in mice

A Massachusetts General Hospital research team has found a surprising potential solution to a persistent clinical problem - the healing of chronic wounds. In their report published in Wound Repair and Regeneration, the investigators from the MGH Vaccine and Immunotherapy Center describe how application of mature B lymphocytes - the immune cells best known for producing antibodies - greatly accelerated the healing of acute and chronic wounds in both diabetic and nondiabetic mice.

Women have higher mortality risk than men in the first year after heart attack

Heart attacks pose a greater threat to women than to men. A team at the Technical University of Munich has determined that in the first year after a heart attack women are subject to a significantly higher mortality risk than men with similar case histories.

Skin plays role in helping regulate blood pressure and heart rate, say scientists

Skin plays a surprising role in helping regulate blood pressure and heart rate, according to scientists at the University of Cambridge and the Karolinska Institute, Sweden. While this discovery was made in mice, the researchers believe it is likely to be true also in humans.

Stem cell researchers make advance toward long-lasting blood vessel repair

Stem cell researchers at Emory University School of Medicine have made an advance toward having a long-lasting "repair caulk" for blood vessels. The research could form the basis of a treatment for peripheral artery disease, derived from a patient's own cells. Their results were recently published in the journal Circulation.

Study identifies protein that plays crucial role in diabetic retinopathy

For millions of Americans, their world is dissolving into an unrecognizable blur. Diabetic retinopathy is an eye disease affecting one-third of the estimated 30 million Americans who struggle with diabetes. As the patients' vision slowly fades, it never recovers and few treatments are available.
