Genetic signals determine neurotransmitter use for communication

Cascades of genetic signals determine which neurotransmitter a brain cell will ultimately use to communicate with other cells. Now a pair of reports from biologists at the University of California, San Diego, have shown for the first time that electrical activity in these developing neurons can alter their chemical fate-and change an animal's behavior-by tweaking this genetic program.

Use of nanomaterials in construction poses potential environmental and health risks

Nanomaterials are poised for widespread use in the construction industry, where they can offer significant advantages for a variety of applications ranging from making more durable concrete to self-cleaning windows. But widespread use in building materials comes with potential environmental and health risks when those materials are thrown away. Those are the conclusions of a new study published by Rice University engineering researchers this month in ACS Nano.

Genetic interaction with diet causes variations in metabolic traits

Ever notice some people seem to eat anything they want and never gain a pound, while others seem to gain weight just by looking at fattening foods. You may be seeing things correctly after all. According to research published in the July 2010 issue of Genetics, this may have a biological cause. Using fruit flies, researchers have found that genes interacting with diet, rather than diet alone, are the main cause of variation in metabolic traits, such as body weight. This helps explain why some diets work better for some people than others, and suggests that future diets should be tailored to an individual's genes rather than to physical appearance.

Nanotechnology approaches to solve major problems on global scale: Report

Nanotechnology refers to a broad range of tools, techniques and applications that simply involve particles on the approximate size scale of a few to hundreds of nanometers in diameter. Particles of this size have some unique physicochemical and surface properties that lend themselves to novel uses. Indeed, advocates of nanotechnology suggest that this area of research could contribute to solutions for some of the major problems we face on the global scale such as ensuring a supply of safe drinking water for a growing population, as well as addressing issues in medicine, energy, and agriculture.

Loss of key nerve cells cause Parkinson's disease: Research

Scientists at the Stanford University School of Medicine have identified a molecular pathway responsible for the death of key nerve cells whose loss causes Parkinson's disease. This discovery not only may explain how a genetic mutation linked to Parkinson's causes the cells' death, but could also open the door to new therapeutic approaches for the malady.

Etubics enters Phase I trials for next generation vector vaccines

Etubics Corporation, a biopharmaceutical company developing next generation vector vaccines, has entered into Phase I trials at Duke University with its ETBX-011, a therapeutic vaccine candidate that is intended to treat Carcinoembryonic Antigen expressing cancers such as colorectal cancer. Etubics dosed its first patient yesterday. Etubics was recently granted clearance by the U.S. Food and Drug Administration for its Investigational New Drug application to begin studying ETBX-011 in humans.

CMX157 shows potential to suppress replication of HIV in Phase 1 clinical trial

Chimerix, Inc., a biopharmaceutical company developing orally-available antiviral therapeutics, today announced the publication of research results demonstrating the potential of CMX157 (hexadecyloxypropyl tenofovir) to effectively suppress replication of human immunodeficiency virus (HIV) that cannot be treated with currently available nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs), including tenofovir disoproxil fumarate (Viread), due to the development of multi-drug resistance. Earlier this year, Chimerix initiated a dose-escalating Phase 1 clinical trial of CMX-157 to evaluate drug safety, tolerability and pharmacokinetics.

Increased SIRT1 protein can delay delay aging, extend lifespan

Researchers watched two groups of mice, both nearing the end of a two-day fast. One group was quietly huddled together, but the other group was active and alert. The difference? The second set of mice had been engineered so their brains produced more SIRT1, a protein known to play a role in aging and longevity.

Athersys reports positive results from MultiStem phase I clinical trial in heart attack patients

Athersys, Inc. announced today positive results from its phase I clinical trial of MultiStem®, its allogeneic cell therapy product, administered to individuals following acute myocardial infarction (AMI), more commonly referred to as a heart attack. The study results, based on four months of post-treatment patient data, demonstrate that MultiStem was well tolerated at all dose levels and also suggest improvement in heart function in treated patients.

Inhibition of MMPs can offer therapeutic benefit in Huntington's disease: Study

A new study reveals that an enzyme linked with multiple disorders is also involved in the generation of toxic, neuron-killing protein fragments in Huntington's disease (HD). The research, published by Cell Press in the July 29 issue of Neuron, provides insight into Huntington's pathology and proposes new therapeutic strategies for this devastating incurable disease.

Aggressive prostate cancer patients tend to retain denser bones

Men who develop prostate cancer, especially the more aggressive and dangerous forms that spread throughout the body, tend to retain denser bones as they age than men who stay free of the disease, suggests new research from Johns Hopkins and the National Institute on Aging (NIA), part of the National Institutes of Health.

Scientists identify new catalytic process to create pharmaceuticals with less chemical waste

Much like two children in the back seat of a car, it can be challenging to get two catalysts to cooperate for the greater good. Now Northwestern University chemists have gotten two catalysts to work together on the same task -- something easily done by nature but a difficult thing to do in the laboratory.The findings, published by the journal Nature Chemistry, will allow medicinal chemists to invent new reactions and produce valuable bioactive compounds faster with less impact on the environment.

The neck played major role in evolution of human brain: Study

By deciphering the genetics in humans and fish, scientists now believe that the neck - that little body part between your head and shoulders - gave humans so much freedom of movement that it played a surprising and major role in the evolution of the human brain, according to New York University and Cornell University neuroscientists in the online journal Nature Communications (July 27, 2010.)
