Think antioxidants will make you live longer? Think again:

We all want to stay as healthy and young-looking as possible, which is why millions of us dutifully take antioxidant supplements such as vitamins C, E and beta-carotene, as well as splashing out on costly antioxidant 'superfoods' such as blueberries.

For years we've swallowed the line from scientists that antioxidants could slow the rate at which our cells - and therefore our bodies - age.  

The theory is that antioxidants reduce the 'oxidising' damage caused by free radicals - corrosive molecules produced by our bodies as we process oxygen, and which we also breathe in from polluted air and smoking.

It is thought that when these free radicals attack proteins and lipids (fats in the cells), it breaks down the cell membrane and damages the DNA inside. This in turn may cause cancerous mutations, as well as making the cells age more rapidly. Free-radical damage to brain cells is also believed to cause the sort of drops in cognitive functioning associated with ageing.

In Britain, we spend £175 million a year on antioxidant supplements - but a new study suggests we might be wasting our money. Not only do free radicals not cause ageing, say researchers at McGill University in Canada, but taking antioxidant pills may actually make our bodies age faster- making them a short cut to an early grave. So what is going on?

The end of heart disease?

Scientists have discovered a way to block the formation of excess cholesterol that leads to heart disease.

Working with mice and rabbits, Johns Hopkins scientists successfully prevented the development of atherosclerosis, the main cause of heart attacks and strokes and the number-one cause of death among humans.

The condition develops when fat builds inside blood vessels over time and renders them stiff, narrowed and hardened, greatly reducing their ability to feed oxygen-rich blood to the heart muscle and the brain.

Working with mice and rabbits, Johns Hopkins scientists successfully prevented the development of atherosclerosis, the main cause of heart attacks and strokes and the number-one cause of death among humans.
Working with mice and rabbits, Johns Hopkins scientists successfully prevented the development of atherosclerosis, the main cause of heart attacks and strokes and the number-one cause of death among humans.

HOW THEY DID IT

Mice used in the experiments were genetically engineered to lack a protein essential in the breakdown of fats and thus were predisposed to atherosclerosis. 
The researchers fed the animals a high-fat diet over the course of several months, but also gave a third of the animals a low-dose of D-PDMP. 
They gave a double dose of the same inhibitor to another third and placebo to the rest.
These effects were observed in animals on a daily D-PDMP treatment even though they ate a diet made up of 20 percent triglycerides - the human equivalent of eating a greasy burger for breakfast, lunch and dinner.
Researchers identified and halted the action of a single molecular culprit responsible for a range of biological glitches that affect the body’s ability to properly use, transport and purge itself of cholesterol — the fatty substance that accumulates inside vessels and fuels heart disease.
 


The offender, the researchers say, is a fat-and-sugar molecule called glycosphingolipid, or GSL, which resides in the membranes of all cells, and is mostly known for regulating cell growth. 

Results of the experiments, the scientists say, reveal that this very same molecule also regulates the way the body handles cholesterol.
The Johns Hopkins team used an existing man-made compound called D-PDMP to block the synthesis of the GSL molecule, and by doing so, prevented the development of heart disease in mice and rabbits fed a high-fat, cholesterol-laden diet.
 
The findings, in the journal Circulation, reveal that D-PDMP appears to work by interfering with genetic pathways that regulate fat metabolism on several fronts - from the way cells derive and absorb cholesterol from food, to the way cholesterol is transported to tissues and organs and is then broken down by the liver and excreted from the body.

Scientists invent portable fertility test enabling men to test the quality of their sperm from their own homes

A portable fertility test enabling men to test the quality of their sperm from the privacy of their own homes has been invented by scientists.

Researchers in the US say their easy-to-use kit could be available to consumers as early as next year, meaning men focussed on their fertility issues would no longer have to endure frequent trips to the doctor to test their sperm.

Greg Sommer and Ulrich Schaff, who founded a startup company to develop their device, say the tests can give a result within minutes.

There are endless controversies in the U.S. about contraception, rape and abortion, with politicians and activists of every stripe chiming in endlessly. But there's not much discussion of women dying in childbirth.
Maybe there should be. 
new study released by the University of Washington's Institute for Health Metrics and Evaluation (IHME) and published in the latest issue of The Lancet  finds that there are only eight countries in the world where maternal mortality rates have risen since 2003, including Afghanistan, countries in Africa and Central America – and the United States.
In 2013, 18.5 mothers in the U.S. died for every 100,000 live births, compared to 7 deaths per 100,000 in Saudi Arabia, 8.2 in Canada and 6.1 in the United Kingdom.

New laser to make stretch marks vanish with minimal pain and downtime

A new laser therapy that bores microscopic holes in the skin is being touted as a way to erase stretch marks on the stomach, thighs and breasts, with minimal pain and downtime. 

The Icon system is the first treatment for the common form of scarring to be approved by the US Food and Drug Administration.

All scars are notoriously difficult to treat, yet exceedingly common; most people have at least one.

A Better Prostate Cancer Test Is Here

Until recently, the PSA test for prostate cancer had been a routine part of every middle age man’s physical. But it has fallen out of favor as doctors realized the PSA was leading many men to have needless and painful prostate biopsies and unnecessary cancer treatments.
In fact, major medical groups have stopped recommending routine PSA testing for most men.

But now a better prostate cancer test has become available to help address the problem.

It’s called the 4Kscore Test.

How aspirin could boost fertility:

Taking aspirin could increase a woman’s fertility, new research suggests.

U.S. scientists found low doses of the drug could improve the chances of conception and of having a live birth.
But, contrary to popular belief, they discovered taking the drug does not prevent miscarriage.

Researchers at the National Institutes of Health say many doctors prescribe low doses of aspirin to women who have had a miscarriage or stillbirth and who want to conceive again.

However, they say the effectiveness of this treatment had not been proven.

So, they randomly assigned more than 1,000 women with a history of pregnancy loss either a low dose of aspirin daily or a placebo.

They then followed them for six months while they tried to conceive.

The researchers found there was no difference in the pregnancy loss rates between the two groups.

But, they did find that women who had experience a single, recent pregnancy loss had an increased rate of pregnancy and live birth while taking a daily aspirin tablet.

These women were classed as those who had lost a baby before four and a half months gestation within the past year.

Heavier Seniors Live Longer: Study

BMI - The Game

A new study suggests that current body mass index (BMI) recommendations may be unsuitable for older adults.
 
Caryl Nowson, a professor of nutrition and aging at Deakin University, led a research team that examined the relationship between BMI and risk of death in people 65 and older. The findings indicated the lowest risk was among those with a BMI of about 27.5, which is considered overweight by the World Health Organization. Mortality was said to increase "significantly" among those with a BMI between 22 and 23, the normal weight range.
 
"It is time to reassess the healthy weight guidelines for older people," Professor Nowson said. "Our results showed that those over the age of 65 with a BMI of between 23 and 33 lived longer, indicating that the ideal body weight for older people is significantly higher than the recommended 18.5-25 'normal' healthy weight range."

9 Not So Obvious but Potentially Deadly Symptoms

Mayo Clinic

Everyone knows the “Call 911!” symptoms — abdominal pain, chest pain, etc. But there are other warning signs that, while they may not warrant a speedy trip to the emergency room, should quickly send you to your doctor. These signs and symptoms, according to experts, should always receive medical attention — pronto.

1. Shortness of Breath. If you’re short of breath or wheezing, and you haven’t been exercising, you may be in trouble. Anything from asthma, pneumonia, and chronic obstructive pulmonary disease to a blood clot in the lung can bring this on, and it needs to be evaluated quickly. Shortness of breath can also be caused by panic attacks brought on by intense anxiety, says the Mayo Clinic.
2. Flashes of light. Flashing lights may signal imminent retinal detachment, says allaboutvision.com. The sensation of flashing lights usually occurs in one eye, but it can be in both eyes at the same time. A shadow over a part of your vision, blurred vision, or the sudden appearance of many “floaters” may also signal an impending detachment. Immediate care may save your sight since a detached retina almost always causes blindness if not treated quickly. A study in the Journal of the American Medical Association found that 1 in 7 people who experience flashes will have a retinal tear or detachment.

3. Unexplained Weight Loss. Almost all of us would love to lose a lot of weight quickly and easily, but if you’re not really trying and all of a sudden you lose 5 percent of your weight in one month or 10 percent over a period of six months, call your doctor. It could mean anything from cancer or diabetes to liver disease, says the Mayo Clinic.
