Mayo Clinic collaboration discovers protein amplifies DNA injury signals

... is mild injury -- such as low doses of sunlight," notes Dr. Chen. "But it's still injury, and we want to repair it as soon as possible so things don't get worse. That's why our question was: How does the cell detect low-dose damage signals? We believe this amplification process involving MDC1 is the answe...

Scientists design potent anthrax toxin inhibitor

Hooked on fishing, and we're heading for the bottom, says scientist

... that needs to be reined in for its own good." He notes that the global fisheries industry is very complex. According to Dr. Pauly, it operates with "one foot deep in illegality," by landing illegal catches, and skirting existing laws through the use of tools such as flags of convenience. And, he says, pu...

Boosting newborns' immune responses

...n animals, and eventually in human babies." Levy notes that the ability to vaccinate newborns ?rather than wait until they reach 2 months of age ?would provide important global health benefits. "Birth is a point of contact with healthcare systems," he says. "Families may not see a health care provider af...

H5N1 avian flu virus vaccine induces immune responses in healthy adults

...ence of a human pandemic of H5N1 avian influenza," notes NIH Director Elias A. Zerhouni, M.D. "We are working hard to address the many challenges that remain with regard to the development of an H5N1 vaccine," adds NIAID Director Anthony S. Fauci, M.D. "For example, potentially protective immune respons...

Cortex matures faster in youth with highest IQ

...o the newly discovered trajectories. However, Shaw notes mounting evidence suggesting that the effects of genes often depends on interactions with environmental events, so the determinants of intelligence will likely prove to be a very complex mix of nature and nurture. Also participating in the study wer...

New male contraceptive clears hurdle

... men would not start for several years. Still, she notes that "We shouldn't be discouraged. We already know that RISUG works, which is half the battle in drug development. Men in studies in India have been using it for more than a decade. Now we just have to finish our homework." RISUG's chief developer, ...

Plants give pests sock in the gut

...ld not appear in the fecal pellets of the insect," notes the Penn State researcher. When used in conjunction with the Bt-toxin, a low dose of Mir1-CP was able to achieve a very high mortality rate in the insects, as well as an extremely low growth rate. "In the long run, the enzyme degrades the insect's...

HIV/AIDS rates in Tijuana, Mexico increasing at alarming rate

...ered a public health priority," said Brouwer. She notes that Mexico is taking many of the right steps in that direction. "For instance, screening of expectant mothers has become more common, with more than 95% of women delivering babies at Tijuana General agreeing to rapid screening and intervention. If...

Birth defects: 8 million annually worldwide

... health problems that can accompany it, the report notes major demographic reasons for the higher rates of birth defects in poorer countries, including more women of advanced age having children and a greater frequency of consanguineous (blood relative) marriages. In countries along the world's "malaria b...

Primates harvest bee nests in Ugandan reserve

...f vines and twigs to make honey dipsticks. Roubik notes that indigenous groups in the Americas use similar honey brushes to harvest honey in areas where Africanized bees are relative newcomers [see photo]. "Most studies of stingless bees have been undertaken in South America and south-east Asia and have ...

Pregnancy drugs can affect grandkids

Scientists directly view immune cells interacting to avert autoimmunity

...efore the disease spreads to the tissue. Krummel notes that the research dispels some assumptions about cellular movement and interaction. Many had assumed that T cells move very little inside the lymph node. The video microscopy shows that they move about one body length per minute, and that much of the...

Tropical Atlantic cooling and African deforestation correlate to drought, report scientists

...nge the terrestrial and ocean system," he says. He notes that droughts in this region are currently occurring more frequently than in the past few thousand years, although the frequency of the droughts is unpredictable. "People in less developed countries live from rain, harvests and animal husbandry," sa...

Access to existing medical treatments could save more lives than spending to improve the treatments

Gene expression profile helps predict chemotherapy response in ovarian cancer patients

..., such as tumor grade or residual disease status," notes Cannistra. "And with the identification of each new gene expression profile, we come one step closer to eventually being able to develop treatments tailored to individual ovarian cancer patients." Coauthors of the study include BIDMC investigators D...

Anyway you slice it, tomatoes cut through drought with new gene

... commercially viable crop, he said. The paper notes that drought conditions throughout the world each year carve out a huge amount of food production. To overcome food shortages, the authors suggest, "it will be necessary to increase the productivity of land already under cultivation and to regai...

RNA splicing occurs in nerve-cell dendrites

...ded mRNA, we also detected the resulting protein," notes Eberwine. "Since the splicing machinery is present in dendrites, one could speculate that if pre-mRNA is present naturally in the dendrite, when activated, it may be spliced and translated, giving rise to many different proteins." Protein diversit...
