Genes may determine success of hip replacement surgery

...in other research, these findings could be used to predict long term success in patients undergoing hip replacement surgery. And they could also be used to develop targeted genetic treatments....

Procedure predicts embryos most likely to result in pregnancy

Antarctic warming to reduce animals at base of ecosystem, shift some penguin populations southward

The warming most global climate models predict will do more harm than simply raise the sea levels...nts to the fact that all the global climate models predict a warming in the Antarctic and a decrease in sea ice along its margins. "Those two things will h...

Map predicting spread of avian flu

... from this outbreak and produced a model which can predict the probability of infection from one farm to another; the 'transmission kernel'. They also identify high-risk areas in the Netherlands and analyze various control strategies, concluding that in these regions an epidemic can only be brought to an end...

Gene expression test reveals ER and HER-2 status of breast tumors

...dy showing that a genomic microarray test can also predict a patient's response to chemotherapy. They also presented a paper in December showing that another genomic index predicts how an ER-positive patient will respond to hormonal therapy. A prospective clinical trial will soon open at M. D. Anderson to...

Some caterpillers just don't want to grow up

... Based on a simple model expansion, the scientists predict that added benefits achieved by slow-developers after emergence would also tip the balance in favor of slow development. It is now a matter of further field and lab work to demonstrate that such benefits exist. ...

Molecular signature may identify cisplatin-sensitive breast tumors

...g p63 and p73 levels in patients?tumors might help predict whether they would benefit from cisplatin therapy." Ellisen is an assistant professor of Medicine at Harvard Medical School. The clinical trial to investigate the role of p63/p73 expression in determining cisplatin sensitivity will be led by MG...

Mosquito genes explain response to climate change

...development of animals. Such information will help predict which animals may survive in changing climates and identify which disease-carrying vectors may move northward, allowing for the production of appropriate vaccines, said William E. Bradshaw and Christina M. Holzapfel, researchers in the department of ...

Using dental X-rays to detect osteoporosis

...e on the ordinary dental radiographs, dentists can predict the osteoporotic condition of the patients to the same extent as the BMD measurements. The image analysis can be automated and does not require extra time on the part of the dentist. The newly developed technique means that patients who are ident...

In presence of fragrant cleaning products, air purifiers that emit ozone can dirty the air

...perimental observations. This model can be used to predict whether a given air purifier will make the air dirtier in a given indoor environment. Scientific data on indoor air purifiers will be important as officials begin the process of regulating air purifiers that emit ozone. In September 2006, Californ...

Ocean's 'twilight zone' may be a key to understanding climate change

...wer in others, complicating scientists' ability to predict the ocean's role in offsetting the impacts of greenhouse gases. Using new technology, the researchers found that only 20 percent of the total carbon in the ocean surface made it through the twilight zone off Hawaii, while 50 percent did in the nor...

New measure of sexual arousal found for both men and women

...ill University and lead author of the study. "I predict that the major physiological measure of sexual arousal for most future clinical trials of female sexual arousal disorder will be genital temperature as measured by thermography," according to Dr. Yitzchak Binik, senior author of the research and Prof...

MIT: Pulsing light silences overactive neurons

...psy could help scientists develop devices that can predict when a seizure is about to occur, allowing treatment (either shock or light) to be administered only when necessary, Boyden said. The technique also offers a way to study other brain diseases, as well as normal brain circuitry, offering insight i...

Colour sensor breath test can detect lung cancer

...esults showed that the test was able to accurately predict the presence of cancer in just under three out of four of those with lung cancer. The results were not affected by age, gender, or stage of disease. Other approaches to breath testing have been used, say the authors. This includes gas chromatog...

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

...factors as age, gender and alcohol consumption to predict such risk, but because of individual variability, these factors don't yield a very accurate prediction. A liver biopsy can indicate the amount of damage to the liver up until the time of the biopsy, but can't reveal how much future damage will oc...
