Youth With HIV Take More Risks After New Meds Introduced

...the groups were very similar in terms of sex, age, race and ethnicity and other socioeconomic characteristics. The 1999-2000 post-HAART group was almost twice as likely as the pre-HAART group to have had unprotected sex in the last three months. On average, post-HAART youth had nearly double the sexual p...

Medical whistleblowers speak out

...uture." Another lesson, says Lenzer, is that "the race to approve new drugs without proper safety testing may be compromising the public's health." A research scientist from a major pharmaceutical company, who participated in the roundtable by speakerphone to protect anonymity, said that "drug companies ...

Live vaccines more effective against horse herpes virus

...ces at the Pimlico Race Course were not allowed to race due to the Churchill Downs quarantine. Because of the outbreak, the NYRA isn't taking any chances. "The New York State Racing Association has put in a directive requiring veterinarians to show that horses have had no fevers for the last three weeks,...

Scientists journey to southern Africa to unravel the secret world of elephant communication

... speeds in different soils. In Salinas, vibrations race through the ground at 1,300 feet a second--twice as fast as in Etosha National Park. Because slower seismic waves maintain their integrity longer, it is possible that elephant vibrations in Etosha would travel farther than in Salinas. "After we did ...

MUHC scientists describe genetic resistance to rampant virus

...hey fight have been locked in an evolutionary arms race for millions of years in an attempt to overwhelm each other. Dr. Vidal and her team have spent the past 10 years studying CMV-resistant mouse strains in an attempt to describe the nature of their genetic resistance. "This research marks our second d...

Could microbes solve Russia's chemical weapons conundrum?

...hemical warfare agents (CWAs). The country faces a race against time to dispose of the stockpile by 2007, in accordance with the Chemical Weapons Convention (CWC). This disposal must be achieved in an ecologically-sound manner. Dr. Inna Ermakova and colleagues from the GK Skryabin Institute of Biochemist...

Asymptomatic HIV babies could use earlier treatment

...dentifying and treating HIV-infected newborns is a race against the clock, according to a study from the Stanford University School of Medicine and Lucile Packard Children’s Hospital. Researchers found that HIV-infected infants treated with one or two antiretroviral drugs within two months of birth were l...

Male Combat Veterans Rank High In Heart Disease Risk

...n cardiovascular risk. After controlling for age, race and education, the study found that combat veterans were 1.9 times more likely to be heavy smokers as opposed to never smokers than non-veterans and 1.2 times more likely to be heavy smokers as opposed to never smokers than non-combat veterans. Comba...

Can our genes tell the story of our divergence?

...ether these explanations - of an evolutionary arms race - prove plausible. We're a long way from understanding why we're so different from our closest primate cousins, but this study provides plenty of tools, and hypotheses, to mine the tiny differences in our DNA for more clues. ### Citation: Nielsen R...

Virologist finds contagious equine flu in dogs

...chers sent fluid and tissue samples from greyhound race dogs that had died from a respiratory illness at a Florida racetrack in January 2004. "Of all animals, dogs have the most intimate contact with humans on a daily basis, so the potential for human infection has to be in the back of our minds," said ...

Gaining ground in the race against antibiotic resistance

Plant defenses prompt bacterial countermeasure in the form of 'island' DNA excision

...hers have essentially caught one step of this arms race in action, and they have shed light on the molecular mechanisms employed by a bacterial pathogen to survive in the face of its host plant's defenses. The research is reported by John Mansfield and colleagues at Imperial College London, the University...
