Bone Density Recovers After Teens Stop Injected Contraceptive
...U.S. women overall. Researchers believe that DMPA interferes with bone mineral density by lowering levels of estrogen, a hormone that promotes bone mineral density in women. The findings appear in the February Archives of Pediatrics and Adolescent Medicine. The study was conducted by Delia Scholes, Ph.D., of ...New understanding of DNA repair may pave way to cancer treatments
...tly, his laboratory developed a small peptide that interferes with ATF2 function, efficiently blocking melanoma growth in mouse models. Ongoing studies are devoted to screening for compounds that mimic the peptide's actions and to allow for further development of the peptide toward clinical assessment.

The papers detail how the team isolated and characterized the gene that encodes B5, called hfl-B5, and used the DNA sequence to find out more about the protein structure of the B5 receptor.

We hope that learning more about this transport machinery might reveal a new target for antiviral drugs in the treatment of HIV-1 disease." ...Bacteria are key to 'green' plastics, drugs

Bennett and San activated a second pathway and stimulated production by adding genes from lactococcus bacteria and sorghum.

.... The new findings show that bright-colored light interferes with magnetoreception such that migratory birds can no longer obtain the information required to head into their migratory direction. The findings point to the existence of two distinct mechanisms of magnetoreceptors in the birds--an inclination comp...Carnegie Mellon University research reveals how cells process large genes
