...African-American women--within those organizations completed a 12-week or a six-week curriculum. Among the findings contained in the UCLA analysis of the program: Feelings of sadness or depression decreased significantly among 12-week participants; fruit and vegetable intake increased significantly a...

Methane-belching bugs inspire a new theory of the origin of life on Earth

...tive back to acetate. Excreting acetate would have completed the cycle. "Our paper," House suggests, "contains a very sensible early metabolism." "It is quite possible," Ferry says reverently, "that this could be the first metabolic cycle." As in virtually every metabolic reaction on Earth, the energy produce...

Researcher studies, treats military with 'silent disease'

... Web site. Of the 90 volunteers enrolled, six have completed the study and 74 are still active. Ten volunteers either dropped out of the study or died. "We are marching toward the end (of the study), and we have about a year and a half until we see the last of the visits," Sjogren said, adding that she's been...

Joslin discovers signs of residual islet cell function in people with long-term type 1 diabetes

...Joslin 50-Year Medalist Study respondents who have completed an extensive health questionnaire, 175 were female and 151 were male, with an average age of 70 years. The average age of diabetes onset was 13 years and average duration of type 1 diabetes 57 years. The data collected so far show that individuals wh...

Worm links cancer risk to ageing

...tween ageing and cancer." The research, which was completed at the Buck Institute in California where Dr Lithgow now works, involved genetically removing checkpoint proteins in the microscopic worm C. elegans. By doing so, the researchers caused a 15-30% increase in the worm's lifespan. "Given the role that ...

Vaccine combined with short-term postexposure antibiotics protects monkeys from inhalational anthrax

... More importantly, only about 44 percent of people completed the whole 60-day course. Thus, minimizing the duration of postexposure antibiotic treatment could be crucial to a successful defense against a large-scale anthrax attack. In the study, two groups of rhesus macaques were exposed to very high amount...

UCSD study reveals how plants respond to elevated carbon dioxide

...sistant professor of biology at Mills College, who completed the study while he was a graduate student working with Schroeder at UCSD, likened this priming to removing ear plugs from someone at a rock concert. "With very good ear plugs, someone might be able to sleep through the concert, but without the earp...

Got inexpensive contrast agent? Milk plays new role in imaging

... 117 received milk. Of the 57 VoLumen patients who completed a subsequent questionnaire, 24 (42 percent) experienced abdominal discomfort such as cramps, diarrhea and nausea, while only 27 (23 percent) of the 117 patients who received milk reported abdominal discomfort. Overall, milk was found to be just as...

Molecular 'on/off switch' controls immune defenses against viruses

...nd liver cancer. In 2005 Dr. Gale and his team completed several breakthrough studies on hepatitis C, discovering that the RIG-I protein binds to viral genetic material. Then, RIG-I changes its shape and sends signals to other proteins that spur production of interferon, a molecule that stops viral replica...

International team analyzes human genetic variation in key immune region

New evidence of early horse domestication

... "That's good, actually," she said of the recently completed nitrogen analyses. "It suggests we've got old stuff." Even more compelling will be if we find long-lived molecules of fat, or lipids, directly attributed to horse manure in the soils, says Olsen. The latest results from Krasnyi Yar site will be...

New biologic treatment for tennis elbow may replace surgery for chronic sufferers

They all had completed a course of physical therapy and had tried some combination of anti-inflammatory medicines, bracing or cortisone shots, all without relief of symptoms. Twenty of the original 140 patients evaluated met these strict criteria and were enrolled in the ...

Mars mission Risk 29: Scientists research ways to reduce radiation-induced brain damage

...ngineering feat. Since 1998, the United States has completed seven Mars missions. Four failed when the Mars landers were lost on arrival. As part of a new push to put a man on Mars, NASA has sketched out a roadmap laying out 45 risks to astronauts in a space mission that is likely to last two years. Those ri...

Researchers barcode DNA of Venice museum's vast fungi collection

...e project, which began in April, is expected to be completed by the end of 2007. "We do not know of any similar project in Europe, at least of this dimension," said Enrico Ratti, the museum's scientific director. "The importance of this project is in the cooperation between different subjects, namely privat...

Key to acute lung injury lies in Ang2 protein

...ne issue of Nature Medicine. The study, which was completed in the laboratory of senior author Jack Elias, M.D., the Waldemar Von Zedtwitz Professor and chair of internal medicine at Yale, looked at the response to hyperoxic acute lung injury (HALI), first in mice and then in human adults and babies. The team...

Using nature's most primitive anti-viral defense system to find new approaches to cancer research

...arlier work when, in collaboration with others, he completed a full study of the function of every one of the fruit fly's genes in cells. This is allowing him now to compare those to similar genes in human cell lines to help him understand why some cancer cells invade and spread to other parts of the body." ...

What does the public really know about HPV?

...en to gauge intentions toward vaccination. It was completed by 635 adults, 49 percent of whom were women. Researchers found: More than half of respondents (56 percent) had heard of HPV and reported that they had seen or heard news or ads about HPV in the past week; Although 42 percent of respo...

Sea urchin genome suprisingly similar to man and may hold key to cures

...Sea Urchin Genome Sequencing Group, which recently completed sequencing of the sea urchin genome and published its findings in the November issue of Science. The National Institutes of Health funded most of the nine-month project. The genome of the purple sea urchin is composed by 814 "letters" coding for 2...

First major study of mammalian 'disorderly' proteins

... critical functions in the cell. The St. Jude team completed the first large-scale collection, investigation and classification of these so-called intrinsically unstructured proteins (IUPs), a large group of molecules that play vital roles in the daily activities of cells. The new technique for collecting an...
