Eating broccoli may keep genetic skin disorder at bay

Eating broccoli is a very good idea for people suffering from a devastating genetic skin disorder, say researchers at the Johns Hopkins University School of Medicine in Baltimore, who found that a natural compound present in the green vegetable could help treat the disorder.
The disorder in question is called epidermolysis bullosa simplex (EBS), which results from mutations in the genes encoding keratin 5 or keratin 14. The mildest form of EBS leads of blistering of the hands and feet since these are most susceptible to frequent abrasion.
Researchers led by Pierre Coulombe found that the compound sulforaphane whose natural precursors are found at high levels in broccoli and other cruciferous vegetables can help meat the disorder.
Coulomb end colleagues turned to sulforaphane in their search for a chemical activator that would induce the production of missing keratins in basal epidermis.

Chemical in fried food may double cancer risk in women

A new study at the University of Maastricht has found that a common chemical called acrylamide caused by frying, roasting or grilling a food substance can double the risk of cancer in women.

The study, which enrolled 120,000 people – half of whom were women – established a direct association between consumption of the chemical and the incidence of ovarian and womb cancer.

It also revealed that the chemical is found in cooked foods such as bread, breakfast cereals, coffee and also meat and potatoes which had been fried, roasted, grilled or barbecued.

The Dutch study discovered that women who had more acrylamide were twice as likely to develop ovarian or womb cancer as those who ingested a smaller amount. The higher amount eaten by the women involved was the equivalent to a single packet of crisps, half a pack of biscuits, or a portion of chips a day.

Walking faster and outpacing death

Researchers who followed the health of nearly 500 older people for almost a decade found that those who walked more quickly were less likely to die over the course of the study published in the Journal of the American Geriatrics Society. The findings, the researchers said, suggest that gait speed may be a good predictor of long-term survival, even in people who otherwise appear basically healthy. The researchers also found that people whose walking speed improved reduced their risk of death.

Smoking may accelerate men’s hair loss

While Asian men generally have less trouble than Caucasians with the most common form of hereditary male baldness, smoking cigarettes may erase that edge, researchers said in a recent study. Smoking may destroy hair follicles, interfere with the way blood and hormones are circulated in the scalp or increase the production of estrogen, the researcher said. The study, published in the November issue of the Archives of Dermatology, recommended that men showing early signs of hair loss should be advised about the role smoking can play to prevent further progression.

Dangers of second hand smoking exaggerated: study

For long the perils associated with passive smoking have been cited as reasons to seek a complete ban on smoking in public places, but if a new study is to be believed the dangers of second had smoke have been exaggerated.
In a new study, long time American anti-tobacco activist and physician Dr Michael Siegal has expressed grave concern over the “obfuscation of facts” about second hand smoke.
“The inaccuracies lie in overstating the effect of a single, transient exposure to second hand smoke – a claim which cannot be validated by any scientific evidence,” he says in the study published in October 10.
Siegal contends that only repeated exposure to second hand smoke is likely to increase the risk of a heart attack for a non-smoker. “As far as the actual possibility of causing a heart attack is concerned, it is all the more likely. For the matter, even chronic exposure to second-hand smoke cannot cause a heart attack in a healthy non-smoker,” he said.
Drawing parallels between eating a single fatty meal and being exposed to second hand smoke for 20-20 minutes, he said, “the 30 and 20 minute claims were based on studies that observed merely ‘changes’ in the heart’s functioning”.

The Three Types Of Tears

Basal, the tears that keeps the eyes moist. Without them, blinking would feel like sandpaper scratching our eyes. We produce between five and 10 ounces a day.

Reflex, the tears that come from cutting onions or a finger in the eye.

Emotional, they are the only tears that dispel toxins.

Women produce 60 percent more prolactin – the same hormone used for breast-feeding – in their tears than man.

Crying is hard in space – gravity issues.

British psychologist John Siaboda concluded that the most tear-inducing musical passage of all time is the beginning of the third movement in Rachmaninoff’s Second Symphony.

Humans are the only animals known to cry, not counting Walt Disney cartoons.

Tear contains mucus, water and oil.

Our noses run when crying because tears drain into the lacrimal ducts inside our eyes and into the nasal cavity.

Can you drink too much water?

We’re always being told to drink water, especially when exercising. But new research shows that under certain circumstances extra water can do more harm than good: if you dilute yourself too much the sodium level in your blood can drop, possibly leading to lethargy, disorientation, seizures and respiratory distress.
