[ Watch the Video: Genomics Reveal The Evolution Of Snakes ] April Flowers for redOrbit.com - Your Universe Online A team of researchers have sequenced the genome of the Burmese python, or Python molurus bivittatus, finding large numbers of rapidly evolved genes in snakes. Their findings, published in Proceedings of the National Academy of Sciences (PNAS), reveal that these genetic changes are linked to extreme characteristics in snakes. The discovery of these characteristics,...

Dr. David Pollock has a simple message for fellow hypertension researchers: think endothelin. In a country where better than 30 percent of adults have high blood pressure and 50-75 percent of those have salt-sensitive hypertension, he believes the powerful endothelin system, which helps the body eliminate salt, should not be essentially ignored. However, the research and clinical world focus on suppressing a better-known system, which prompts the body to hold onto salt, said Pollock,...

Scientists are learning more about how protein gets in the urine when the kidneys begin to fail and how a new drug blocks it. "We have known for a long time that renal failure comes with protein in your urine, especially in diabetes," said Dr. David Pollock, renal physiologist at the Medical College of Georgia Vascular Biology Center. It's also known that a new class of drugs called endothelin A receptor antagonists reduce protein in the urine. New research published in the journal...

Researchers may have found why women have an edge in keeping a healthier balance between the amount of salt they eat and excrete - at least before reaching menopause. Premenopausal women are known to have fewer problems with salt-sensitive hypertension and hypertension in general, but afterward their risks are essentially the same as men, says Dr. David Pollock, renal physiologist in the Vascular Biology Center at the Medical College of Georgia. The reason appears to be related to female...
