Liposuction: Fat shows up again

A new study has revealed that the fat removed by liposuction returns and gets ‘redistributed upstairs’ — around the shoulders, arms and upper abdomen after a year.
Rudolph Leibel, an obesity researcher at the University of Columbia said the body controls the number of fat cells as carefully as it controls the amount of fat. When a fat cell dies, it grows a new one to replace it.

Liposuction, however, surgically destroys the fishnet structure under the skin, which may be why the fat cells don’t regrow in the place from which they were removed. Instead the body compensates for their loss by growing new fat cells in other areas.

“It’s another chapter in the ‘You can’t fool Mother Nature’ story,” Leibel said. The study involved 32 women aged in their mid-30s and of average weight. Just under half (14) had a modest amount of fat removed by liposuction from their hips and thighs, while the remainder (18) acted as controls.

Identical measurements of all the women were carried out at six weeks, six months and a year, which revealed how the body ‘defends’ its fat.

After six weeks the treated patients had lost 2.1 per cent of their fat, compared to 0.28 per cent in the control group, but this difference had disappeared at one year. Though the women’s thighs remained thinner after a year, the missing fat had found its way back to their stomachs.

Shedding skin flakes actually cuts indoor air pollution

A new study has found that flakes of skin that people shed at the rate of 500 million cells every day are not just a nuisance — the source of dandruff, for instance, and a major contributor to house dust — but they actually can be beneficial.

It concluded that oil in those skin cells makes a small contribution to reducing indoor air pollution.

Charles Weschler and colleagues explained that humans shed their entire outer layer of skin every 2-4 weeks at the rate of 0.001 - 0.003 ounces of skin flakes every hour. Those flakes contain skin oils, including cholesterol and ‘squalene’, and are a major constituent of the dust that accumulates on tables and other surfaces in homes and offices.

Past research suggested that squalene from passengers’ skin had a role in reducing levels of ozone — a pollutant that can irritate the eyes, nose and throat and worsen asthma symptoms — from the air in airplane cabins.

“It is only within the last five years that we’ve grown to appreciate the central role that squalene (from human skin oil) plays in oxidation chemistry within indoor environments,” the study said.

Therapies to beat stress may improve IVF success rates

Women undergoing in vitro fertilization (IVF) treatment stand a chance of higher pregnancy rate through the mind/body therapies, according to a new study.

These therapies enable women taking infertility treatment to beat stress and anxiety effectively.

“The intersection of stress and fertility is a controversial one, but we do know that stress can reduce the probability of conception,” said Alice Domar, Director of the Domar Center for Mind/Body Health at Boston IVF.

To study the effects of the mind/body therapies on IVF pregnancy outcomes, Domar’s team conducted a comparison test on women aged 40 years or below with normal hormonal levels.
