Single molecule FRET techniques combined with wavelet transforms give new view of AMPA receptor

A digital signal processing technique long used by statisticians to analyze data is helping Houston scientists understand the roots of memory and learning, Alzheimer's and Parkinson's diseases and stroke.

Lifestyle, rather than hereditary factors, plays major role in life expectancy

How long your parents lived does not affect how long you will live. Instead it is how you live your life that determines how old you will get, reveals research from the University of Gothenburg recently published in the Journal of Internal Medicine.

Researchers identify immune cell population that acts as body's border patrol with the outside world

So-called barrier sites -- the skin, gut, lung - limit the inner body's exposure to allergens, pollutants, viruses, bacteria, and parasites. Understanding how the immune system works in these external surfaces has implications for understanding such inflammatory diseases as asthma, psoriasis, IBD, and food allergies, all of which occur at the body's barriers.

Hematopoietic stem cells are less fixed, more flexible than previously thought: Study

The bone marrow stem cells responsible for generating new blood cells are less fixed and more flexible than previously thought, according to a paper published online on February 7 in the Journal of Experimental Medicine.

NKT, DSM sign contract to develop therapeutics based on natural killer T cells

DSM Biologics, a business unit of DSM Pharmaceutical Products, today announced the signing of a contract with NKT Therapeutics, Inc. based in Waltham, Mass, USA, the biotechnology company that focuses on developing therapeutics based on unique immune cells called natural killer T cells.

Higher vitamin D levels and sun exposure linked to lower risk of multiple sclerosis

People who spend more time in the sun and those with higher vitamin D levels may be less likely to develop multiple sclerosis (MS), according to a study published in the February 8, 2011, print issue of Neurology®, the medical journal of the American Academy of Neurology. MS is a chronic disease of the brain and spinal cord, usually with recurrent flare-ups of symptoms. It is often preceded by a first episode (or event) of similar symptoms lasting days to weeks.

TREK1 activity offers a key target for fluoxetine and other antidepressant drugs

Using a unique and relatively simple cell-based fluorescent assay they developed, scientists with the U.S. Department of Energy's Lawrence Berkeley National Laboratory and the University of California, Berkeley have identified a means by which fluoxetine, the active ingredient in Prozac, suppresses the activity of the TREK1 potassium channel.

Study identifies genetic variation linked with increased risk of major depression

Numerous studies have shown that the brain molecule neuropeptide Y (NPY) helps to restore calm after stressful events. A team of University of Michigan-led researchers has now found that people whose genes predispose them to produce lower levels of NPY are more responsive to negative stimuli in key brain circuits related to emotion - and are therefore less resilient in the face of stress and may be at higher risk for developing a major depressive disorder.

Breakthrough in Thermal Gradient's fast PCR technology for molecular diagnostics

Thermal Gradient, a Rochester, NY biotech company, announces a breakthrough in its fast PCR technology for molecular diagnostics. PCR is the preferred critical step in virtually all forms of DNA testing.

Women more attracted to men when not sure about his feelings

Are you still looking for a date for Valentine's Day? Here's some dating advice straight from the laboratory: It turns out there may be something to "playing hard to get." A study published in Psychological Science, a journal of the Association for Psychological Science, finds that a woman is more attracted to a man when she is uncertain about how much he likes her.

Researchers develop new method for drug discovery using math to combat HIV, other diseases

Using mathematical concepts, Princeton researchers have developed a method of discovering new drugs for a range of diseases by calculating which physical properties of biological molecules may predict their effectiveness as medicines.

Munich research team provides promising alternative to DNA-based procedures

Defects in the genome are the cause of many diseases. Gene therapy - direct replacement of mutant genes by intact DNA copies - offers a means of correcting such defects. Now a research team based at the Medical Center of the University of Munich, and led by Privatdozent Dr. Carsten Rudolph, has taken a new approach that avoids DNA delivery.

Researchers identify enzyme that protects against inflammation, joint destruction

A team of researchers at the University of Gothenburg, Sweden, has identified an enzyme that protects against inflammation and joint destruction. Made when the researchers blocked production of the enzyme GGTase-I in transgenic mice, this unexpected discovery could lead to the identification of new mechanisms that control the development of inflammatory disorders, as well as new medicines.

Immune system genes linked to personality traits, mental illness and suicidal behaviour

Genes linked to the immune system can affect healthy people's personality traits as well as the risk of developing mental illness and suicidal behaviour, reveals a thesis from the University of Gothenburg, Sweden.

Two new sources of soybean may replace fish meal in weanling pig diets

Two new sources of soybean meal are capturing attention throughout the country. University of Illinois research indicates that fermented soybean meal and enzyme-treated soybean meal may replace fish meal in weanling pig diets.

Researchers identify CHK1 protein may serve as treatment target for neuroblastoma

After analyzing hundreds of proteins produced by the DNA of tumor cells, researchers have identified one protein that may be central to a new treatment for the often-fatal childhood cancer neuroblastoma. Oncologists hope to translate the finding into pediatric clinical trials of a drug that blocks the protein's activity.

Ornim receives FDA 510(k) clearance for non-invasive monitoring of blood flow in tissue

Ornim, Inc. is pleased to announce the receipt of 510(k) clearance from the U.S. Food and Drug Administration (FDA) to market the CerOx 3210F monitor. Additionally to its previous clearance for non-invasive monitoring of regional hemoglobin oxygen saturation in the brain or skeletal muscle, the CerOx 3210F is now also intended for use as a non-invasive monitor of blood flow in tissue of adults.
