Critical tuning dial for controlling whole body energy

Researchers have found what appears to be a critical tuning dial for controlling whole body energy, according to a new report in the January issue of Cell Metabolism, a Cell Press publication. When energy levels within cells drop, it sets off a series of events designed to increase the amount of calorie-rich dietary fat that the body will absorb.

New mouse model with deficiency of lipoprotein lipase in neurons

Researchers at the University of Colorado School of Medicine have created a new and exciting mouse model to study how lipid sensing and metabolism in the brain relate to the regulation of energy balance and body weight. The research team, led by Hong Wang, PhD, created mice with a deficiency of lipoprotein lipase (LPL) in neurons, and observed two important reactions.

Researchers create model that predicts drug effects on fetal development

When pregnant women need medications, there is often concern about possible effects on the fetus. Although some drugs are clearly recognized to cause birth defects, and others are generally recognized as safe, surprisingly little is known about most drugs' level of risk. Researchers in the Children's Hospital Boston Informatics Program have created a preclinical model for predicting a drug's teratogenicity based on characterizing the genes that it targets.

Blocking activation of delta-PKC enzyme could protect lungs from neutrophil-mediated damage

All of us may be able to breathe a little easier now that scientists from Pennsylvania have found a new therapeutic target for controlling dangerous inflammation in the lungs. A new research report in the January 2011 issue of the Journal of Leukocyte Biology (http://www.jleukbio.org) suggests that blocking the activation of an enzyme called delta-protein kinase C (delta-PKC) could protect the lungs from neutrophil-mediated damage, which can result in out of control inflammation.

Fruit fly faeces provides answers to pregnant women's bloating and constipation

Clues about how the human gut helps regulate our appetite have come from a most unusual source - fruit fly faeces. Scientists at the University of Cambridge are using the fruit fly to help understand aspects of human metabolism, including why pregnant women suffer from bloating and constipation, and even the link between a low calorie diet and longevity.

Low-radiocarbon nutrition permanently reduces genetic damage to brain cells

A new method of child and maternal nutrition could prevent a specific type of genetic damage that would otherwise occur in up to 160 million brain cells in each person over their lifetime. Preventing this genetic damage could have significant implications related to aging and cancer.

Removal of ZIP proteins from hippocampus cell protects them from injury

Researchers in the Blue Bird Circle Developmental Neurogenetics Laboratory in the department of neurology at Baylor College of Medicine have discovered that zinc enters cells through specialized protein gates known as ZIP transporters, and removing these ZIP proteins from cells in the hippocampus significantly protects them from injury.

Metabolic cost of missing one night of sleep equivalent to walking two miles

In the first-ever quantification of energy expended by humans during sleep, a University of Colorado team has found that the metabolic cost of an adult missing one night of sleep is the equivalent of walking slightly less than two miles.

Researchers develop unique vaccine that produces long-lasting anti-cocaine immunity in mice

Researchers from The Scripps Research Institute, Weill Cornell Medical College, and Cornell University have produced a long-lasting anti-cocaine immunity in mice by giving them a unique vaccine that combines bits of the common cold virus with a particle that mimics cocaine.

Study suggests new experimental drug is better than standard morphine

A little-known morphinelike drug is potentially more potent, longer lasting and less likely to cause constipation than standard morphine, a study led by a Loyola University Health System anesthesiologist has found.

Study: Stem cells play an unexpected role in male pattern balding

Given the amount of angst over male pattern balding, surprisingly little is known about its cause at the cellular level. In a new study, published in the Journal of Clinical Investigation, a team led by George Cotsarelis, MD, chair of the Department of Dermatology at the University of Pennsylvania School of Medicine, has found that stem cells play an unexpected role in explaining what happens in bald scalp.

Dutch scientists provide new insights into intestinal cancer through plant study

Dutch scientists have gained important new insights into intestinal cancer from studying a plant. The disease is called Peutz-Jeghers Syndrome, a hereditary disorder where people develop intestinal polyps that turn into malignant tumors.

TRPM2 in pancreatic beta-cells may control insulin secretion levels

The research group led by professor Makoto Tominaga and Dr. Kunitoshi Uchida, National institute for Physiological Sciences, found TRPM2 ion channel in pancreatic beta-cells is important for insulin secretion stimulated by glucose and gastrointestinal hormone secreted after food intake. Their finding was reported in Diabetes.

New research finds pattern for detecting 'false-positive' ANA results

The presence of antinuclear antibodies (ANA) indicates the possibility of autoimmunity and the indirect immunofluorescence (IIF) assay on HEp-2 cells is the standard blood test (ANA-HEp-2) used to detect ANA. However, studies have shown that a "false-positive" ANA test occurs in up to 13% of healthy individuals. In such cases the test detects the presence of autoantibodies that apparently are not associated with autoimmunity.

People fail to understand consequences of social trauma felt by bullied victims

Taunted, harassed, and pushed to a deadly breaking point. Last year, stories of teen bullying brought to life the heartbreaking consequences of young lives cut short by ruthless and unchecked behavior. While recent media coverage of these violent acts has increased national awareness of bullying's deadly consequences, it has done little to stop it from happening.

ddn conducts interview with lead plaintiff related to embryonic stem cell research case

Drug Discovery News, a news organization covering issues, trends and product news in the pharmaceutical drug development and discovery industry, recently conducted exclusive interviews with the lead plaintiffs in the controversial Sherley v. Sebelius lawsuit challenging President Barack Obama's order granting funding for embryonic stem cell research.

Low-fat lupin proteins

In emerging countries such as China or Brazil, meat consumption is rising dramatically. Indeed, worldwide consumption of red meat has quadrupled since 1961. The United Nations Food and Agriculture Organization (FAO) expects increasing prosperity to lead to a doubling of global meat production by the year 2050. The question is whether our planet, with its limited farmland resources, will still be able to meet all of our needs into the future.

Fundamental similarities in response to wasp infection and blood cancer development

Tiny parasitoid wasps can play an important role in controlling the populations of other insect species by laying their eggs inside the larvae of these species. A newly hatched wasp gradually eats the host alive and takes over its body.
