Cancer vaccines -- Taking a jab at cancer by stimulating the immune system

...to prevent cervical cancer, shows that the vaccine continues to protect against HPV types 16 and 18 at five and a half years into the study, according to researchers from the University of Louisville. Their findings also show that the vaccine offers significant cross-protection for HPV types 45 and 31. The...

Scientists sequence genome of parasite responsible for common sexually transmitted infection

...e January 12 issue of Science. "The progress that continues to be made in deciphering the genomes of organisms, such as the Trichomonas vaginalis parasite, helps to further our collective scientific understanding of these organisms, so that we can better address public health issues," says NIH Director Elias ...

UW launches study testing adult stem cells for heart damage repair

...erson who suffers from chronic myocardial ischemia continues to experience insufficient flow of oxygen-rich blood to the heart despite optimum medical intervention. This type of therapy - regenerative medicine - treats diseases by using growth factors, genes or stem cells to promote blood vessel or tissue g...

Researchers discover gene crucial for nerve cell insulation

...onditions, the unaffected copy of an affected gene continues to produce its protein. However, the researchers found that the mutant EGR2 copy interferes with the interaction between the normal EGR2 gene and another myelin gene, SOX10, as the two try to work together to produce the myelin protein MPZ. The...

Fighting to keep Darwin in the classroom

...specially human life—out of the science curriculum continues unabated. And though a number of educational institutions and organizations have had notable success in combating intelligent design in the classroom, what is needed now is a fresh source of evolution materials and anti-creationism ammunition for ou...

Anti-wrinkle compound causes pathological reaction in skin cells

...not a unique case in the world of beauty products, continues the researcher. "Several compounds found in cosmetics are just as complex as medication—they are absorbed through the skin, flow through the bloodstream, are expelled by the kidneys, or stocked in cells or even in the liver. Yet, the laws regulating ...

How trees manage water in arid environments

...e Arizona monsoon usually begins around July 7 and continues for the next two months, resulting in about one-third of the region's yearly rainfall. The monsoon varies from year to year in starting date, duration and intensity. "The semi-arid forest ecosystem adapts to the extremes in the annual cycle of wat...

Male reindeer inflate a large air sac in the neck region to emit their hoarse rutting calls

... female's air sac stops growing, whilst the male's continues to develop. The authors of the research paper further explain that the rutting calls appear to be understood by rival males as an indicator of the caller's fighting ability. By contrast to male red deer, who are renowned for roaring with the he...

Despite their heft, many dinosaurs had surprisingly tiny genomes

... for hundreds of millions of years, a process that continues in modern birds. "Our work debunks the theory that the small, repeat-poor genomes typical of birds may have co-evolved with flight as a means of conserving energy," says Edwards, professor of organismic and evolutionary biology in Harvard's Facult...

Better health twice as likely for nonsmokers who live and work with smoking restrictions

... smoking restrictions. "As the policy environment continues to move toward comprehensive protection at the workplace, the household increasingly will become the main and perhaps the only significant source of exposure among nonsmoking adults as it is among children," observes Donna Shelley, MD, Mailman School...

...ts. The saphenous vein taken from a patient’s leg continues to be the most commonly used graft for coronary artery bypass grafting even though a significant percentage of vein grafts eventually fail. Arterial grafts are the preferred conduits because they are less prone to becoming obstructed. However, they a...
