Male contraception: One door opens, another closes

...ice at a tenth of the disease-treatment dose. With safety testing already out of the way, they thought this male "Pill" could potentially be brought to market very quickly. Because of the growing public interest in male contraceptives, researcher Dr. John Amory at the University of Washington, Seattle wa...

New drug blocks influenza, including bird flu virus

... remains to determine optimal dosage, efficacy and safety before the drug can be tested in a human patient. One possibility is that the new agent could be used as part of an anti-influenza cocktail of drugs, much like those used to treat HIV infection. The team hopes to move the research into preclinical ph...

New study suggests promising drug combinations for sleeping sickness

The aim was to find out if any of these combinations would provide a viable treatment option for patients with second-stage sleeping sickness, where infection has reached the brain and prognosis is norm...

Amateur boxing linked to brain cell injury

...fewer blows to the head and because they must wear safety equipment, the effects tend to be less severe. These studies have been based on assessment of thinking, learning, memory and other brain functions long after boxing, rather than an immediate test performed soon after a fight.

...tions, which could be vital in the areas of public safety and homeland security," added Vida Ilderem, vice president of the Embedded Systems Research Labs at Motorola, Tempe, Ariz. The researchers report the advance in a paper, "Tuning the chemical selectivity of SWNT-FETs for detection of heavy metal ion...

Hope for a more effective and less toxic cancer drug

... Much more remains to be done to assess the drug's safety and effectiveness in patients, but early results from the laboratory are promising. Our hope is that the new drug will prove to be more effective while having fewer side effects." The findings of the scientific assessment team are published in th...

New research to cut animal testing

...lieve that animal testing will disappear from drug safety assessment in the short term as you can't ask human volunteers to take novel drugs straight from testing done in tube tests," said Dr Walmsley. "But if we can refine the pre-animal tests and increase people's confidence in them, then we will be abl...

Male circumcision reduces HIV risk, study stopped early
