New test helps identify hepatitis C patients at high risk of developing cirrhosis

A researcher at the Stanford University School of Medicine has helped confirm the reliability of a new test for liver disease that is ushering in the long-promised era of personalized medicine based on each individual's genetic makeup. The Stanford group was ...

Major link in brain-obesity puzzle found

...ssue of the Journal of Clinical Investigation, U-M researcher Liangyou Rui, Ph.D. and his team report their findings on a protein called SH2B1, and specifically on its activity in brain cells. Using a variety of genetic, diet and hormone techniques, they were able to show that the action of SH2B1 regulates ...

New imaging technique tracks traffic patterns of white blood cells

...are the hallmark of the disease," said Mount Sinai researcher Dr. Paul S. Frenette. "In vivo imaging provides a window inside the body that allows us to see exactly which blood cells and which molecular constituents participate in the vascular occlusions. Advances in molecular imaging will likely lead to new t...

Common cold virus may kill breast cancer cells

University of Newcastle researcher Kathryn Skelding, funded by the National Breast Cancer Foundation and Viralytics Ltd, has been working on a new treatment which only affects cancer cells ?this would be an improvement on conventional chemotherapy and radiation treatment, which also i...

Something new under the sun

...house in the correct climate is nothing new. Dutch researcher Rachel van Ooteghem has designed a control system for an improved solar greenhouse that yields more. In the new greenhouse, good climate control with sustainable energy resulted not only in an increased crop yield but also a lower gas bill. Factors...

Salmonella survives better in stomach due to altered DNA

...tant to at least five different antibiotics. Dutch researcher Armand Hermans found new genetic information in DNA of DT104 that might be involved in its survival and infection mechanism. This genetic information might also be involved in the increase in the number of infections caused by this pathogen. By com...

Stress hormones may play new role in speeding up cancer growth

...blood vessels into tumor cells. Earlier work by researcher Anil Sood at the University of Texas had shown that the same stress hormones can stimulate ovarian tumor cells to produce these three compounds. The key to that discovery was that the two stress hormones ?epinephrine and norepinephrine ?would bind to...

Key to zebrafish heart regeneration uncovered

... damaged tissue," said Kenneth Poss, Ph.D., senior researcher for the team, which published the findings on Nov. 3, 2006, in the journal Cell. First authors of the paper were Alexandra Lepilina, M.D., and Ashley Coon. "Interestingly, some species have the ability to regenerate appendages, while even fairly c...

New study aims to stop sepsis in its tracks

...veral years ago by Emanuel Rivers, M.D., M.P.H., a researcher and physician at Henry Ford Hospital in Detroit, where it dramatically increased survival rates. To implement this approach across the entire country is a daunting task. As a first step, the consortium aims to find out whether the protocol will hav...

OHSU researchers demonstrate how white blood cells cannibalize virus-infected cells

...t dye themselves," explained Mark Slifka, Ph.D., a researcher in the VGTI who led the research. Slifka is also a scientist in the Division of Pathobiology and Immunology at the Oregon National Primate Research Center and holds a concurrent appointment in the Department of Molecular Microbiology and Immunology i...

One-of-a-kind imaging probe reveals secrets useful for drug discovery

...rate the technique partly because it combined lead researcher Aaron Dossey's passion for studying insects with his formal training in biochemistry. "I've raised different species of walking sticks, which are well known to spray defensive venom," Dossey said. "We thought if this technique really can look at sma...

Stem cells engage in dialogue with the cells that regulate their futures

...em cells and niche cells," said UW stem-cell niche researcher Hannele Ruohola-Baker, professor of biochemistry and a member of the UW Institute for Stem Cell and Regenerative Medicine. "Demonstrating that stem cells can contribute to niche function has far-reaching consequences for stem-cell therapies and may p...

Male contraception: One door opens, another closes

...he growing public interest in male contraceptives, researcher Dr. John Amory at the University of Washington, Seattle was able to obtain funding to test the drug's effect in seven healthy men. The result? Nothing--no effect on fertility, even at a dose high enough to cause diarrhea, stomach upset, and other un...

NHGRI aims to make DNA sequencing faster, more cost effective

...are needed if they are to be useful to the average researcher or physician," said Jeffery Schloss, Ph.D., NHGRI's program director for technology development. "We look forward to seeing which of these technologies fulfill their promise and achieve the quantum leaps that are needed to take DNA sequencing to the ...

Heavy smoking cuts women's chance of pregnancy -- even with donated oocytes

...e) was also comparable between the groups. Lead researcher Dr Sérgio Soares, Director of the IVI Clinic in Lisbon, said: "The non-heavy smokers had a significantly higher pregnancy rate, with over half becoming pregnant (52.2%), compared with just over a third (34.1%) of the heavy smokers. "This means we ...
