Chewing up a key regulator of fat synthesis keeps mice lean despite a high-fat diet

...velop type 2 diabetes within 10 years, unless they lose 5 to 7 percent of their body weight--about 10 to 15 pounds for someone weighing 200 pounds. Defining how molecules regulating fat storage interact could lead to novel measures to curb obesity. Further evidence linking TRB3 to disease comes from rece...

DNA: Bacteria's survival ration

...f these genes, the bacteria cannot consume DNA and lose their competitive advantage. "The gene family is found in many other species," the authors reported, "suggesting that the use of DNA as a nutrient may be a widespread phenomenon." The concept of nutritional competence could have applications to med...

U of M study examines kidney stone prevention in astronauts

...veloping kidney stones while in space. Astronauts lose calcium in their bones and strength in their muscles while in space because of the zero-gravity environment. This calcium can end up in their kidneys, putting them at risk for developing kidney stones. At least 14 American crew members have develop...

One-third of adults with diabetes still don't know they have it

...abetes can often prevent or delay diabetes if they lose a modest amount of weight by cutting calories in their diet and increasing physical activity (for example, walking 30 minutes a day 5 days a week). A major study of people with IGT has shown that lifestyle changes leading to a 5 to 7 percent weight ...

It's not fair! We are programmed to resist weight loss

...an body is designed to strongly resist attempts to lose weight will be presented at an international gathe...odies have strong mechanisms to defend attempts to lose weight but very weak mechanisms to prevent weight gain. Dr King's weight loss intervention studies...

New protein target may advance design of HIV and cancer drugs

...from the protein chain. This causes the protein to lose its tertiary structure or overall shape. For these molecules, shape is an important property that enables the protein to carry out certain biological functions. The process, active site displacement, involved design of a platinum drug with higher a...

Alaska seal pup diet may hold key to decline of population

...at content in winter before laying their eggs, but lose about one-third of their fat after releasing their eggs.) Except for the fat content of the herring, the nutrient content was the same for both groups, Polasek explained. The researchers monitored the animals in the low fat group to ensure fat intak...

Thinner and younger

...ars. "We know people on calorie restriction will lose weight," says Fontana. "But this study isn't a weight-loss study. We're hoping to learn more about whether calorie restriction can alter the aging process. Fontana says, for example, that low-grade, chronic inflammation seems to mediate aging. Over...

Aging cells, aging body: Fresh evidence for a connection

...ir skin significantly increases. Over time, cells lose their ability to divide, a state known as replicative senescence. The new research, published in an advanced online edition of Science, is the first to quantify the presence of replicatively senescent cells in any species. "For 40 years, we've known...

Tumor cells that border normal tissue are told to leave

...breast tumors. Boundary tumor cells were shown to lose surface proteins that attach them to other cells and stabilize their position within tissues. The study demonstrated that it was the difference in Src activity that led to the change in the attachment proteins. When a high Src cell (tumor cell) was n...

Researchers test new way to quit smoking

The aim of our research is to discover if there is a measurable difference in quitting success rates between the two groups in our trial...

However, fMRI studies cannot demonstrate a causal role for the VWFA, and lesions involving the VWFA invariably involved other regions as well. Now, a patient whose surgery to...

How 'hot' emotional brain interferes with 'cool' processing

"Also, the three types of distracters gave us good controls, which allowed us to clearly establish that the observed effects were due to the presence of emotional distraction rather than to the presence of other meaningful (neutr...

NJIT engineer poised to take stem cell research a step forward

...ne, Arinzeh says. In many such surgeries, patients lose their limbs. But if her method of implanting stem cells is shown to induce bone repair, amputation may not be necessary. Stem cells could also help patients suffering from osteoporosis, whose fractured bones could be regenerated by the cells. Arinz...

The Amazon in 2050: Implementing the law could save a million square kilometers of rainforest

The region of greatest loss of mammals will be in the eastern Amazon, where expanding agriculture will overrun many species with small ranges. Of the major highways ...

Successful cell engineering may lead to mad cow prevention, say researchers

More than 180,000 cases of BSE have been confirmed worldwide, including recent cases in the United States. The disease can be passed to humans, and more than 100 such cases have been confirmed, most of...
