Overweight Has Become The Norm For American Women

Overweight Has Become The Norm For American Women.
Almost one-quarter of green women who are overweight in reality perceive themselves as being normal weight, while a sizable minority (16 percent) of women at conformist body weight actually fret that they're too fat, according to a young study. The study found these misperceptions to be often correlated with race: Black and Hispanic women were much more indubitably to play down their overweight status compared with whites, who were more apt to worry that they weighed too much, even when they didn't. Although the boning up looked mostly at low-income women attending public-health clinics in Texas, the findings do reflection other studies in different populations, including a recent Harris Interactive/HealthDay poll.

That appraisal found that 30 percent of adult Americans in the "overweight" class believed they were actually normal size, while 70 percent of those classified as tubby felt they were simply overweight. Among the heaviest group, the morbidly obese, 39 percent considered themselves fundamentally overweight. The problem, according to office lead author Mahbubur Rahman, is the "fattening of America," meaning that for some women, being overweight has become the norm.

And "If you go somewhere, you associate with all the overweight people that think they are normal even though they're overweight," said Rahman, who is helpmeet professor of obstetrics and gynecology at the Center for Interdisciplinary Research in Women's Health, University of Texas Medical Branch at Galveston (UTMBG). In fact, "they may even be overweight or normal-weight and consider they are totally small compared to others," added study senior writer Dr Abbey Berenson, director of the Center for Interdisciplinary Research in Women's Health at UTMBG.

The further findings are published in the December issue of Obstetrics & Gynecology. The bone up looked at more than 2200 women who had arrived at a public-health clinic for reproductive assistance, such as obtaining contraceptives. According to the burn the midnight oil authors, more than half of these reproductive-age women (20 to 39 years), who were the issue of this trial, were above a normal body mass index (BMI). An even higher proportion of black Americans (82 percent) and Mexican Americans (75 percent) were overweight or obese.

Cancer Cells Can Treat Tumors

Cancer Cells Can Treat Tumors.
New analysis suggests that many cancer cells are equipped with a big-hearted of suicide pill: a protein on their surfaces that gives them the ability to send an "eat me" special to immune cells. The challenge now, the researchers say, is to put faith in out how to coax cancer cells into emitting the signal rather than a dangerous "don't eat me" signal. A chew over published online Dec 22 2010 in Science Translational Medicine reports that the cells cast out the enticing "eat me" signal by displaying the protein calreticulin.

But another molecule, called CD47, allows most cancer cells to keep destruction by sending the different signal: "Don't eat me". In earlier research, Stanford University School of Medicine scientists found that an antibody that blocks CD47 - turning off the gesture - could support fight cancer, but mysteries remained. "Many normal cells in the body have CD47, and yet those cells are not stilted by the anti-CD47 antibody," Mark Chao, a Stanford graduate student and the study's lead author, said in a university info release.
