Genetic roots of bipolar disorder revealed by first genome-wide study of illness

... were found in both populations, strengthening the validity of the results. A subsequent study is examining whether the results apply to other populations, and will look for common variations among them. The researchers will soon make the results of their scans available, on a website, to other scientists...

Elucidation of the genome for diabetics with DNA chips

...rld for a common disease like DT2 ?demonstrate the validity of this approach. The method will be made available in France in March 2007, through the CNRS genotyping platform at Lille, largely funded by the Nord-pas-de-Calais Regional Council. These advances should make it possible to unravel genetic predispos...

Growth hormone is not the anti-aging bullet for healthy adults

...outh," Liu said. "We wanted to see if there is any validity behind some of the claims made about growth hormone's anti-aging properties. "Our biggest surprise was the general lack of research that had been done in this area. When we reviewed the scientific evidence, we found that there were really only ab...

Application of Genomatix in silico methods reveals novel cancer associated genes

... an ever increasing number of scientists proof the validity of our concepts and experience the value of our integrated approach. This excellent work, carried out by researchers at The Conway Institute of the University College, Dublin, The Mater Misericordiae University Hospital in Dublin and The Beth Israel ...

The connector rotation hypothesis? Phage do not pack their DNA by rotation

... But further testing will be needed to confirm the validity of that model to the degree of certainty with which this team rejected the rotator hypothesis. ...

Gorilla susceptibility to Ebola virus: the cost of sociality

...o estimate Ebola-induced mortality and to test the validity of different possible contamination scenarios. The authors of the study showed that transmission between gorillas was particularly important within groups and led to a very high mortality rate--97% of group-dwelling individuals. In contrast to the hy...

Production of key Alzheimer's protein monitored for first time in humans

...ism," Bateman says. "If further study confirms the validity of our test, it could be very valuable for determining which drugs go forward in clinical trials and at what doses." The test also may be useful in diagnosis of Alzheimer's prior to the onset of clinical symptoms, which occurs after Alzheimer's has...

Alleged 40,000-year-old human footprints in Mexico much, much older than thought

...y were still hot, which raises the question of the validity of the footprints. If they were hot, why would anybody be walking on them?" The British researchers, funded by the United Kingdom's Natural Environment Research Council, have promoted their hypothesis widely, most prominently at a July 4, 2005, pres...

Kenya halts first field trials of GM maize

Songa was quoted in Kenya's Sunday Nation newspaper on 28 August as saying that local scientists had yielded to pressure f...

European Commission funds EBI to do new research on synergies between bioinformatics and medical informatics

The outbreaks involved two serotypes of avian influenza: one low and one highly pathogenic H7N1 and a low pathogenic H7N3 virus. Seven individuals exposed to the more recent outbreak of low pathogenic H7N3 tested seropositive for H7N3. T...

Biased reporting found in cancer prognostic studies

...of information, some are beginning to question the validity and possible biases in many of the studies. To examine the question of selective reporting bias, Panayiotis A. Kyzas and colleagues from the University of Ioannina in Greece analyzed information from studies that investigated the association between...

Strongest proof yet found for prion hypothesis

...owever, scientists have been unable to confirm its validity by causing a TSE in normal lab animals by infecting them with malformed proteins (dubbed "prions" by Prusiner) created entirely in a test tube. Such an approach eliminates the possibility that some other agent might be causing the disease. In a pape...

Unexpressed But Indispensable -- The DNA Sequences That Control Development

For this Elgar and colleagues chose the zebrafish, because its transparent embryo is ideal for observing developmental events. They injected individual CNEs into embryos, along with a gre...
