UW-Madison scientists return to rat as biomedical research tool
...as the ability to knock out genes." The ability to add or subtract genes to an animal's genome lends powerful insight into the basic mechanisms of disease. New methods of disease prevention and treatment in humans, as well as a better basic understanding of development, physiology and pathology have resu...Diabetes in the elderly linked to fewer cellular 'power plants'
... remarkable statistic," said Shulman. "And, if you add impaired glucose tolerance, you're talking about forty percent of the population." The estimated economic burden of diabetes in United States is about $100 billion per year, a substantial proportion of which is due to diabetes in the elderly, said th...Chemical in broccoli blocks growth of prostate cancer cells
...nutrition in 2002. These latest findings appear to add new burnish for this class of chemicals that has already shown promise in prior studies as a therapeutic agent for breast and endometrial cancer. For instance, a 1998 study by Bjeldanes and Firestone showed that I3C keeps breast cancer cells from dup...Research suggests a new method to protect groundwater quality

Now, a study conducted at the edge of Israels Negev Desert has come up with what might be a piece of the puzzle. ...Muscle-repair defect underlies two muscular dystrophies
...and MM, Campbell said. One possibility would be to add the dysferlin protein from the outside, he said. While most people wouldnt believe that the protein could pass through the membrane, a functional fragment of the protein might make it through a membrane that is already damaged.

"Whenever we would add these growth factors, at the end of the day we would have many different types of blood cells but no more stem cells than we started with," Weissman said. The ability to grow hematopoietic stem cells would help doctors who need large numbers of these...Multiple lifestyle changes effectively lower blood pressure

...n chemotherapy cant be predicted just by trying to add up the effects of the different drugs used in the therapy, Evans said. But now we have real, detailed proof that combination therapy isnt just the sum of its parts.

Next-generation membranes are expected to add to the advantages of membrane separation over traditional, competing technologies such as cryogenic distillation and selective adsorption and absorption processes.

This has helped scientists to understand problems caused by defective genes, for example, which have now been linked to thousands of human diseases. So far the technology has been limited to small segments of DNA....$2.48 million to advance research on multiple sclerosis
