Many paramedics do not get enough clinical experience in insertion of emergency breathing tubes

Across the United States, many patients require insertion of emergency breathing tubes before arriving to a hospital, but emergency medicine researchers at the University of Pittsburgh School of Medicine have found that many paramedics - the highest level of prehospital providers - do not get enough clinical experience in this life-saving skill.

Activist groups hinder important clinical trials of HIV medication

One promising approach to help stem the global HIV epidemic is to give commercial sex workers an HIV medication (such as the drug tenofovir) before they have high risk sex in the hope of reducing their chances of becoming infected, an approach called "pre-exposure prophylaxis" (PREP).

Would boosting the oxytocin (OT) hormonal system lead to longer breast-feeding?

There's little controversy about the benefits of breastfeeding infants over giving them formula. Mother's milk is the perfect food, providing exactly the correct nourishment for newborns, while protecting them from many illnesses.

Hormonal signaling systems and their role in sex drive

Two University of Edinburgh professors from the Centre for Integrative Physiology describe how "our understanding of how the brain processes information is undergoing a radical shift as we begin to recognize the implications of hormonal signaling systems within the brain itself," explained Gareth Leng.

First generation of HIV vaccines may be available within 10 years but availability doesn't guarantee uptake

Public health officials must be sensitive to concerns about stigma and fear of vaccine-induced infection if they want women to take advantage of HIV vaccines now under development, says a University of Toronto researcher.

Smokers who give up are much less likely to lose their teeth prematurely

Dental researchers at the University of Newcastle upon Tyne, UK, observed a group of cigarette smokers with chronic gum disease over one year and found some symptoms were more likely to improve in the people who quit during the study period.

New discovery could help in the fight against cancer

University of Michigan researchers have figured out one more component in cancer cells' aggressive growth - and hope that knowledge can help kill the cells.

Researchers have identified a protein that is crucially involved in how our memories are stored and processed

University of Queensland researchers have identified a protein that is crucially involved in how our memories are stored and processed, paving the way for new strategies to treat conditions certain mental disorders.

We should be extra wary of making social blunders when we are under strain or fatigued

Some of us can hold our tongues better than others but even the best of us will blurt out the truth when we're tired, stressed or distracted, according to a new research report.

New finding has potentially major implications for anti-angiogenic therapy

Scientists supported by the National Institute of Dental and Craniofacial Research (NIDCR) have added a key new piece to the puzzle of how tumor cells induce new blood vessels to form and fuel their abnormal growth, a well-known process called angiogenesis.

Compound derived from cottonseed could help improve the effectiveness of chemotherapy at treating head and neck cancer

The findings, which appear in the July issue of the journal Molecular Cancer Therapeutics, could lead to a treatment that provides an effective option to surgically removing the cancer, helping patients preserve vital organs involved in speech and swallowing.

Variations in the gene for protein kinase C beta 1 (PRKCB1) strongly associated with autism

This exciting finding suggests some answers to a number of previous, but unexplained, observations about autism and provides the potential for a mechanistic explanation for some of the characteristics of the condition. The results of the study are published today in the journal Molecular Psychiatry.

New treatment option for bad breath

More than 90 million Americans can sigh comfortably because of new relief for their bad breath. Dental experts today revealed research highlighting a new treatment option that can eliminate halitosis or chronic bad breath at the Academy of General Dentistry's (AGD) 53rd Annual Meeting in Washington, D.C.

Asthma may be linked to a decreased risk of brain cancer

According to new research there is a suggestion that gene variants known to raise the risk of asthma, might also decrease the risk of a common type of brain cancer that progresses rapidly and is fatal.

Ethical guidelines suggested for stem cell research in primates

Before conducting research that involves putting human stem cells into the brains of nonhuman primates such as monkeys or apes, scientists and oversight committees should consider a series of ethical criteria, according to a policy paper released in the July 15 issue of Science.

NIPA levels act as switch regulating cell division

Cells control mitosis (cell division) by assembling a biochemical switch to block it or by disassembling the switch to trigger it, according to investigators at St. Jude Children's Research Hospital and the Technical University of Munich.

Oxytocin raises aggression, cuts anxiety during lactation

Maternal aggressive/protective behavior is recognized throughout mammalian species, especially during lactation. When hiking, we warn our kids not to approach bear cubs, or to get between a cub and the mother. While driving and you see a fawn, you know a doe can't be too far away and will run headlong to protect it.
