Asthma gene clusters identified

...table asthma. Also, in addition to differentiating between an acute and stable asthma attack, the genetic profile may be useful in identifying an imminent asthma attack. Researchers examined 54,675 genes. They discovered eight gene clusters in all, consisting of 161 genes. At least one cluster was identifie...

Expression Project for Oncology (expO) completes first phase of standardized gene expression analyses

...eservation rate of 75%. Due to close collaboration between the surgeons, pathologists, local clinical research coordinators and expO, the success rate achieved in preserving these samples was 100%. Such well-preserved tissue allows the subsequent analysis to more precisely reflect the tumor’s biology. "We a...

Effective Cancer Treatments Follow The Clock

Cricket's finicky mating behavior boosts biodiversity

...onsists of eight to 15 transfers of spermatophores between male and female, says Mendelson. The final spermatophore, or capsule, to be transferred contains the actual sperm cells that impregnate the female. As a species begins to split into two separate species, says Mendelson, "the songs appear to be the f...

Wisconsin researchers identify sleep gene

..., fruit flies generally are quiet and immobile for between six and 12 hours each night and lose most of their ability to respond to stimuli, the researchers found. When deprived of sleep, humans and their winged counterparts rebound on the following night by sleeping longer and more deeply. Flies also sleep ...

PET/MRI scans may help unravel mechanisms of prenatal drug damage

"Understanding how drugs are transferred between a mother and her fetus during pregnancy may help us unravel the mechanisms of the drug's damaging effects on unborn children," said SNM member Helene Benveniste, M.D., Ph.D., chair of Brookhaven's medical department in Upton, N.Y., and lead author of...

Camera Traps Catch Eye of the Tiger
