Researchers at the University of Pennsylvania School of Medicine are harnessing two new, non-invasive techniques to look more closely inside the working lungs – leading to early detection of diseases, like emphysema, before it becomes evident in other modes of imaging.
Scientists have discovered a new type of cell that appears to play a role in the development of cancer ? a highly volatile, precancerous stem cell that can either remain benign or become malignant, depending upon environmental cues.
Researchers at Virginia Commonwealth University?s Massey Cancer Center studying the interaction between the immune system and cancer cells have identified interferon gamma as one of the signaling proteins involved with tumor relapse.
In order to differentiate and specialize, stem cells require very specific environmental cues in a very specific order, and scientists have so far been unable to prod them to go through each of the necessary steps. But now, for the first time, a study in mice by Rockefeller University scientists shows that embryonic stem cells implanted in the brain appear to develop into fully differentiated granule neurons, the most plentiful neuron in the cerebellum.
What if there was an outbreak of avian flu in Pennsylvania and public health officials had to institute quarantines to stop the spread of the deadly disease? How would the state?s courts respond if someone resisted or challenged a quarantine in court, particularly since no Pennsylvania case law, statute or court ruling has ever established specifically who can petition a court to institute a quarantine or what procedures to follow to do so?
Medically treating post-partum depression may not be enough to improve a mother?s relationship with her baby, and is only part of the equation, according to a new study done in part by the University of Alberta.
Researchers at the Yale School of Medicine Child Study Center and 10 other institutions will share a $10 million gift from James and Marilyn Simons of The Simons Foundation to create a databank of DNA samples from autism patients around the country.
Researchers at the University of Illinois have found that adolescence is a time of remodeling in the prefrontal cortex, a brain structure dedicated to higher functions such as planning and social behaviors.
Using advanced brain imaging techniques, researchers at Georgetown University Medical Center have watched how humans use both lower and higher brain processes to learn novel tasks, an advance they say may help speed up the teaching of new skills as well as offer strategies to retrain people with perceptual deficits due to autism.
Aga Khan University (AKU) is proud to share a peer-reviewed article, “Factors Associated with Adherence to Anti-Hypertensive Treatment in Pakistan,” which will appear in the March 14 issue of PLoS ONE, the international, open-access online journal from the Public Library of Science.
