Researchers make surprise discovery that some neurons can transmit three signals at once

...se glutamate to still be released. Finding such an association would be intriguing, but for now this remains just an hypothesis that will require much study, Dr. Gillespie said. The third author of the study is Gunsoo Kim, Ph.D., who is now pursuing post-doctoral studies at the University of California, San Fra...

Mystery Blood Vessel Disorder Implicated In 'Mini' Strokes

...ssel disease. "This study is the first to show an association between intracranial arterial dolichoectasia and the whole spectrum of small vessel disease abnormalities, thus defining a new cerebrovascular syndrome," said Amarenco. The researchers will continue to follow the patients in this study (the GENIC st...

Computational Method Speeds Mapping of Cell Signaling Networks

...Bayesian network analysis can not only identify an association between signal molecules A and B, it can detect whether B depends on A for transfer of the signal. The team's analysis predicted all but three of 18 well-studied T-cell network relationships. Although the work was largely a "proof of principle" repo...

...ies will be able to show whether this is a genuine association or not." The study did not find a statistically significant difference between boys born to mothers who smoked or who worked in a potentially harmful environment where they might be exposed to heat, vibration or chemical, but the prevalence of crypt...

Research advances quest for HIV-1 vaccine

...o determine the structure of the complex formed by association of 4E10 with a peptide fragment that is identical to the section of gp41 that the antibody recognizes. The researchers identified the specific amino acids on gp41 that 4E10 interacts with and the 3D structure adopted by these amino acids. These study...

It's not all genetic: Common epigenetic problem doubles cancer risk in mice

...Although Feinberg and others have already noted an association between loss of imprinting of IGF2 and colon cancer in people, the current experiments were designed to find out whether the loss of imprinting is involved in cancer's development or just in its progression. "Most researchers, including me, expect e...
