Holiday gluttony can spell disaster for undiagnosed diabetics

...f eating sugar. Sugar, as any other food, provides excess calories that can lead to obesity and a predisposition to diabetes," Dr. Chandalia said. "If you don't eat sugar, and continue to eat extra calories from other foods, you may still develop diabetes." ...

Biofuel cells without the bio cells

...ctrons to chemicals outside the cell, to discharge excess energy generated during metabolism. This maintains energy flow in the cell and, in turn, keeps the cell alive. The process has worked a little like that slogan for a hyper-electrified desert gambling town: What happens in the cellular environs stay...

Pesticides need sunscreen to beat the heat

...It could also mean cleaner waters, as the risks of excess pesticide contamination will be lowered. "It can be used for many other pesticides. We are considering it as a platform carrier material for pesticides and have looked at several pesticides, including this oil-soluble avermectin, and water-soluble...

PLoS ONE is launched by the Public Library of Science

...submissions only in August, it already receives in excess of 100 submissions each month and launches with the publication of 100 peer-reviewed research articles. The volume of articles is unprecedented for a journal launch, and is an indication of the strong support within the research community for the PLo...

High hourly air pollution levels more than double stroke risk

...d that high hourly rates of particulate matter (in excess of 200 ug/m3) around two hours before death were associated with a more than doubling in the risk of death from a bleed into the brain. The findings held true, irrespective of the average daily level of air pollutants. No such effect was found for ...

For super-obese patients, duodenal switch beats gastric bypass

Better sludge through metagenomics

...the process to make it more reliable." Removing excess phosphorus from wastewater can be most economically accomplished by environmentally friendly biological means in a process known as enhanced biological phosphorus removal (EBPR). The researchers were able to obtain a nearly complete genetic blueprint...

High dopamine transporter levels not correlated with ADHD

...?proteins on dopamine-producing cells that take up excess dopamine ?they could end up with depleted dopamine levels and reduced motivation/attention. Four independent studies have reported that ADHD subjects have higher than normal levels of dopamine transporters in a brain region called the striatum. But...

UCSD study reveals how plants respond to elevated carbon dioxide

...faster. The assumption is that plants will take up excess carbon dioxide to produce carbohydrates--their stored energy source. However, studies have shown that, contrary to expectations, increased carbon dioxide does not accelerate plant growth. Previous research has also shown that the doubling of atmosp...

Eat less, weigh more? Enzyme makes lean mice 'susceptible' to dietary fat

...from the brain tell cells in the body to store the excess energy by converting it to fat. Weight gain results when food intake greatly exceeds energy expenditure. But when the brain's appetite/energy regulator is out of whack, so are the rules for gaining and losing weight. "How do you know when to stop ea...

MRSA vaccine shows promise in mouse study

New angiogenesis finding may help fight cancer growth

...ganizing into blood vessels, Bresnick says, "Maybe excess levels of NK-B are responsible for or contribute to impaired vascular development/function and certain symptoms of preeclampsia." According to the Preeclampsia Foundation, the condition affects about 200,000 American women each year. Many angioge...

Increased sensitivity to nerve signals keeps diabetes at bay

...In contrast, mice genetically altered to harbor an excess number of beta cell M3 receptors show the opposite: a profound increase in glucose tolerance and insulin release, the researchers found. Moreover, such animals become resistant to developing symptoms of diabetes or prediabetes when fed a high-fat die...

Gene linked to rare disease activates fat breakdown

...as triglycerides. In vertebrates including humans, excess nutritional carbohydrates and fat are efficiently converted into triglycerides and deposited in fat tissue. The team, led by Rudolf Zechner of the University of Graz in Austria, now reports that CGI-58 boosts the activity of so-called adipose trigl...

Higher levels of obesity associated with greater health risks

...able health risk and that accounting for degree of excess weight is important in understanding weight-related health risk. Overall, extremely obese women were more likely to die over the average 7.0 years of follow-up than were women in other examined weight categories. Modeling analyses adjusted for age, s...

Discovery could aid fight against cystic fibrosis infection

... PA," Mougous said. "The bacterium thrives in the excess mucus that accumulates in their lungs. Once a PA infection in a CF patient's lung has been established, these hardy bacteria are difficult or impossible to clear, which over many years eventually results in the death of the patient. Our paper provide...

Speeding the search for elusive chromosomal errors

...ount of genetic material, or microduplications, an excess of genetic material. Individually, many genomic diseases are rare, but collectively, they may occur in one in 1,000 live births. Frequently the gene aberrations harm multiple organ systems. For example, patients with chromosome 22q11.2 deletion syn...

Natural vitamin E tocotrienol reaches blood at protective levels
