Growing a blood vessel in a week

Technology for creating new tissues from stem cells has taken a giant leap forward. Three tablespoons of blood are all that is needed to grow a brand new blood vessel in just seven days. This is shown in a new study from Sahlgrenska Acadedmy and Sahlgrenska University Hospital published in EBioMedicine.

To reap the brain benefits of physical activity, just get moving

Everyone knows that exercise makes you feel more mentally alert at any age. But do you need to follow a specific training program to improve your cognitive function? Science has shown that the important thing is to just get moving. It’s that simple.

Decreased ability to identify odors can predict death

For older adults, being unable to identify scents is a strong predictor of death within five years, according to a study published October 1, 2014, in the journal PLOS ONE. Thirty-nine percent of study subjects who failed a simple smelling test died during that period, compared to 19 percent of those with moderate smell loss and just 10 percent of those with a healthy sense of smell.

Elderly face no added risk from cosmetic surgery, study finds

Senior citizens are at no higher risk for complications from cosmetic surgery than younger patients, according to a recent study by plastic surgeons. The doctors analyzed data from more than 129,000 patients during a five-year period and found no significant difference in the rate of complications for individuals older or younger than 65.

Direct brain interface between humans

Researchers have successfully replicated a direct brain-to-brain connection between pairs of people as part of a scientific study following the team’s initial demonstration a year ago. In the newly published study, which involved six people, researchers were able to transmit the signals from one person’s brain over the Internet and use these signals to control the hand motions of another person within a split second of sending that signal.

Unethical Cash Payments for Diagnosing Dementia

Leading doctors and health campaigners are urging the government to withdraw its Dementia Identification Scheme, whereby English GPs are to be paid £55 for every dementia diagnosis they make from now until next April.

Moderate drinking is healthy only for some people, study finds

A new study confirms that moderate alcohol consumption can protect against coronary heart disease. But only for the 15% of the population that have a particular genotype.

Disgust leads people to lie and cheat; Cleanliness promotes ethical behavior

While feelings of disgust can increase behaviors like lying and cheating, cleanliness can help people return to ethical behavior, according to a recent study. The study highlights the powerful impact emotions have on individual decision-making.

Could Depression Actually Be a Form of Infectious Disease?

Major depressive disorder (MDD) should be re-conceptualized as an infectious disease, according to a professor. A new article suggests that major depression may result from parasitic, bacterial, or viral infection. The article presents examples that illustrate possible pathways by which these microorganisms could contribute to the etiology of MDD.

Cannabis extract can have dramatic effect on brain cancer, says new research

Experts have shown that when certain parts of cannabis are used to treat cancer tumors alongside radio therapy treatment the growths can virtually disappear.

Secondhand marijuana smoke may damage blood vessels as much as tobacco smoke

Secondhand marijuana smoke may have similar cardiovascular effects as tobacco smoke. Lab rats exposed to secondhand marijuana smoke had a 70 percent drop in blood vessel function.

Spice up your memory: Just one gram of turmeric a day could boost memory

Adding just one gram of turmeric to breakfast could help improve the memory of people who are in the very early stages of diabetes and at risk of cognitive impairment.

Trans fat consumption linked to diminished memory in working-aged adults

Trans fat consumption is adversely linked to memory sharpness in young to middle-aged men. Men under 45 years old who ate higher amounts of trans fats, which are found in processed foods, had significantly reduced ability to recall words. Further studies need to determine whether these effects extend to women under 45 years old.

Early detectable vascular disease linked to erectile dysfunction

Men who have multiple detectable subclinical vascular abnormalities are more likely to develop erectile dysfunction. The presence of coronary artery calcification may predict the future onset of erectile dysfunction.

Cocaine users experience abnormal blood flow, risk heart disease

Cocaine users have subtle abnormalities in blood flow through the heart’s smallest blood vessels. The abnormalities can occur while the heart appears normal on imaging test, putting cocaine users at risk for heart disease or death.

Testosterone replacement therapy does not increase cardiovascular risks in men with low testosterone levels

An important new study of men who have undergone testosterone replacement therapy has found that taking supplemental testosterone does not increase their risk of experiencing a major adverse cardiac event, such as a heart attack or stroke.

New school meal requirements: More harm than good?

New federal regulations requiring school meals to contain more whole grains, less saturated fat and more fruits and vegetables, while perhaps improving some aspects of the food being served at schools across the United States, may also be perpetuating eating habits linked to obesity, diabetes and other diet-related diseases, an analysis has found.

High heels may enhance a man’s instinct to be helpful

A French study is the first to investigate the effect of a woman’s shoe heels on men’s behavior. If it’s help a woman needs, maybe she should wear high heels. That’s the message from researchers after they observed how helpful men are towards women in high heels versus those wearing flat, sensible shoes.

New article shows daily use of certain supplements can decrease health-care expenditures

Use of specific dietary supplements can have a positive effect on health care costs through avoided hospitalizations related to Coronary Heart Disease (CHD), according to a new article published in the Journal of Dietary Supplements(1). The article, “From Science to Finance—A Tool for Deriving Economic Implications from the Results of Dietary Supplement Clinical Studies,” published by Christopher Shanahan and Robert de Lorimier, Ph.D., explores a potential cost-benefit analysis tool that, when applied to a high-risk population (U.S. adults over 55 with CHD) who take dietary supplements, specifically omega-3 fatty acid or B vitamin dietary supplements, can result in the reduction of the individuals’ odds of experiencing a costly medical event.

Hand dryers can spread bacteria in public toilets, research finds

Modern hand dryers are much worse than paper towels when it comes to spreading germs, according to new research. Airborne germ counts were 27 times higher around jet air dryers in comparison with the air around paper towel dispensers.
