PHILADELPHIA – A recently described master regulator protein may explain the development of aberrant cell growth in the pancreas spurred by inflammation

A team from the Perelman School of Medicine at the University of Pennsylvania profiled gene expression of mouse pancreatic ductal and duct-like cells from different states - embryonic development, acute pancreatitis and K-ras mutation-driven carcinogenesis - to find the molecular regulation of these processes.

TORONTO, ON – Cities around the world can significantly reduce greenhouse gas (GHG) emissions by implementing aggressive but practical policy changes, says a new study by University of Toronto Civil Engineering Professor Chris Kennedy and World Bank climate change specialist Lorraine Sugar, one of Kennedy's former students.

A multi-site clinical trial including the University of Colorado Cancer Center shows that the benefit of Bright IDEAS problem-solving skills training goes beyond teaching parents to navigate the complex medical, educational, and other systems that accompany a child's diagnosis of cancer – the training also leads to durable reduction in mothers' levels of anxiety and symptoms of posttraumatic stress, and improves overall coping with a child's illness. Results of the study were published online last week in the Journal of Clinical Oncology.

COLUMBIA, Mo. – Health care transition (HCT) services help young people with special health care needs such as asthma or diabetes move from pediatric to adult health care. However, youths with autism spectrum disorder (ASD) have less access to these services, which are designed to prevent gaps in care and insurance coverage. A University of Missouri researcher recommends that the medical community develop HCT services for individuals with ASD as a way to ensure consistent and coordinated care and increase their independence and quality of life.

A large-scale field experiment conducted during the December 2011 parliamentary elections in Russia suggests that fraud had a significant impact on the results. The research marks an advance in efforts to quantify vote fraud.

Simon Fraser University evolutionary biologists Bruce Archibald and Rolf Mathewes, and Brandon University biologist David Greenwood, have discovered that modern tropical mountains' diversity patterns extended up into Canada about 50 million years ago.

Their findings confirm an influential theory about change in modern species diversity across mountains, and provide evidence that global biodiversity was greater in ancient times than now.

The scientific journal Palaeogeography, Palaeoclimatology, Palaeoecology has published their research.

A Simon Fraser University chemist is the lead author on a new paper that advances scientific understanding of the structure and function of glycoproteins, in particular the number and positioning of sugars on them.PLOS ONE, an international, peer-reviewed, open-access, online, scientific research journal, has just published the paper, N-glycoproteome of E14.Tg2a Mouse Embryonic Stem Cells.

Creeping climate change in the Southwest appears to be having a negative effect on pinyon pine reproduction, a finding with implications for wildlife species sharing the same woodland ecosystems, says a University of Colorado Boulder-led study.

JACKSONVILLE, Fla. — Researchers at Mayo Clinic have discovered an abnormal protein that accumulates in the brains of many patients affected with two common neurodegenerative disorders — amyotrophic lateral sclerosis, also known as ALS or Lou Gehrig's disease, and frontotemporal dementia.

When is it time for parents to back away? A new study shows that college students with overcontrolling parents are more likely to be depressed and less satisfied with their lives. This so-called helicopter parenting style negatively affects students' well-being by violating their need to feel both autonomous and competent. The work, by Holly Schiffrin and colleagues from the University of Mary Washington in the United States, is published online in Springer's Journal of Child and Family Studies.

Troy, N.Y. – A new study from engineers at Rensselaer Polytechnic Institute and the University of California, Berkeley, pairs light and genetics to give researchers a powerful new tool for manipulating cells. Results of the study, published in the journal Nature Methods, show how blue light can be used as a switch to prompt targeted proteins to accumulate into large clusters.

More and more opioids are being prescribed for pain relief in Germany. This is the conclusion arrived at by Ingrid Schubert, Peter Ihle, and Rainer Sabatowski, whose study of a sample of inhabitants of the state of Hesse with health insurance from a large statutory provider is published in the latest issue of Deutsches Ärzteblatt International (Dtsch Arztebl Int 2013; 110(4): 45-51).

New Rochelle, NY, February 12, 2013—About 16,000 women on active duty in the U.S. military give birth each year. Most return to service after 6 weeks and can be deployed after 4 months. The potential for an increased risk of depression among new mothers who deploy and are exposed to combat experience is presented in a study published in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers.

New Rochelle, NY, February 12, 2013—About 1 in 150 children are affected by an autism spectrum disorder (ASD), a group of neurodevelopmental disorders characterized by difficulty with language, communication, and social interaction. A critical review of several published studies evaluating the potential for therapy or assistance dogs to help children with ASD overcome some of these challenges is published in The Journal of Alternative and Complementary Medicine, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers.

Toronto – If an employee's performance drops in one area, does that mean they're slacking off?

It could mean that they've simply shifted and refocused their efforts on a different set of tasks -- a positive sign of adaptability that should be considered in performance evaluations, says a study lead by a researcher at the University of Toronto's Rotman School of Management.
