Endocrine Reviews gets top Impact Factor ranking

In its recently released annual Journal Citation Report (JCR) for 2008, Thomson Reuters awarded Endocrine Reviews the top Impact Factor ranking among the 93 journals competing in the “Endocrinology & Metabolism” category.

Deet is neurotoxic

The active ingredient in many insect repellents, deet, has been found to be toxic to the central nervous system. Researchers writing in the open access journal BMC Biology say that more investigations are urgently needed to confirm or dismiss any potential neurotoxicity to humans, especially when deet-based repellents are used in combination with other neurotoxic insecticides.

New microchip technology may accelerate drug discovery for cancer, other diseases

Flasks, beakers and hot plates may soon be a thing of the past in chemistry labs. Instead of handling a few experiments on a bench top, scientists may simply pop a microchip into a computer and instantly run thousands of chemical reactions, with results - literally shrinking the lab down to the size of a thumbnail.

Tiny device to 'sniff out' disease, heart attacks, poison and environmental pollution

Like the sensitive seismographs that can pick up tremors of impending earthquakes long before they strike, a similar invention from Tel Aviv University researchers may change the face of molecular biology.

Gene expression patterns in cancer could aid early screening and prevention

Distinctive patterns of genes turned off - or left on - in healthy versus cancerous cells could enable early screening for many common cancers and maybe help avoid them, Medical College of Georgia scientists say.

University at Buffalo start-up provides innovative digital sperm analysis to infertile couples worldwide

Couples struggling with fertility problems have a new option for assessing their ability to have a child with the start-up of a new Buffalo-based company called LifeCell Dx, Inc. (LCDX).

Music drives experimental samples through a lab-on-a-chip

Music, rather than electromechanical valves, can drive experimental samples through a lab-on-a-chip in a new system developed at the University of Michigan. This development could significantly simplify the process of conducting experiments in microfluidic devices.

Airway cells are chemosensory

The same mechanism that helps you detect bad-tasting and potentially poisonous foods may also play a role in protecting your airway from harmful substances, according to a study by scientists at the University of Iowa Roy J. and Lucille A. Carver College of Medicine.

Johns Hopkins-designed animal tuberculosis "tracker" to speed drug and vaccine studies

Johns Hopkins researchers have developed a novel way to monitor in real time the behavior of the TB bacterium in mouse lungs noninvasively pinpointing the exact location of Mycobacterium tuberculosis. The new monitoring system is expected to speed up what is currently a slow and cumbersome process to test the safety and efficacy of various TB drug regimens and vaccines in animals. Plans are already under way for developing a similar system to monitor TB disease in humans.

Experts warn about electronic cigarettes

The U.S. Food and Drug Administration today announced that a laboratory analysis of electronic cigarette samples has found that they contain carcinogens and toxic chemicals such as diethylene glycol, an ingredient used in antifreeze.

Rates of secondhand smoke exposure high among college students

Secondhand smoke (SHS) is not only a nuisance, but a potential health concern for many college students, and administrators should be taking steps to reduce students' exposure, according to a new study by researchers at Wake Forest University School of Medicine.

Child’s IQ can be affected by mother’s exposure to urban air pollutants

A mother's exposure to urban air pollutants known as polycyclic aromatic hydrocarbons (PAHs) can adversely affect a child's intelligence quotient or IQ, a study reports. PAHs are chemicals released into the air from the burning of coal, diesel, oil and gas, or other organic substances such as tobacco. In urban areas motor vehicles are a major source of PAHs.

Implantable device offers continuous cancer monitoring

Surgical removal of a tissue sample is now the standard for diagnosing cancer. Such procedures, known as biopsies, are accurate but offer only a snapshot of the tumor at a single moment in time.

Nanoparticle-based “chemical nose” sniffs out cancer earlier to improve treatment options

Using a "chemical nose" array of nanoparticles and polymers, researchers at the University of Massachusetts Amherst have developed a fundamentally new, more effective way to differentiate not only between healthy and cancerous cells but also between metastatic and nonmetastatic cancer cells. It is a tool that could revolutionize cancer detection and treatment, according to Vincent M. Rotello, Ph.D., M.Phil., and D. Joseph Jerry, Ph.D., M.S., the investigators who led the study.

Scientists develop process for 'surgical' genetic changes

Research led by scientists at Iowa State University's Plant Sciences Institute has resulted in a process that will make genetic changes in plant genes much more efficient, practical and safe.

FDA issues draft guidance on drug anticounterfeiting

The U.S. Food and Drug Administration has issued a draft guidance on the use of inks, pigments, flavors, and other physical-chemical identifiers (PCIDs) by manufacturers to make drug products more difficult to duplicate by counterfeiters, and to make it easier to identify the genuine version of the drug.
