Researchers Discover Pathway that Eliminates Genetic Defects in Red Blood Cells (8/7/2007)

Researchers at the University of Pennsylvania School of Medicine have discovered a unique molecular pathway that detects and selectively eliminates defective messenger RNAs from red blood cells. Other such pathways – known as surveillance pathways – operate in a more general way, in many cell types. Knowing how this specific surveillance system works can help researchers better understand hereditary diseases, in this case, thalassemia, a form of anemia, which is the most common genetic disorder worldwide. ...> Full Article

Researcher Pioneers Combined Stroke Therapy (8/7/2007)

The odds of recovering from a stroke are one out of seven when a clot-busting drug is administered to a patient in the first three hours post-stroke. But the odds are even better when the drug is used in combination with an experimental device, a therapy pioneered by a University of Alberta researcher. ...> Full Article

Does This Child Have Appendicitis? Watch Out for Key Signs (8/7/2007)

A 5-year-old with abdominal pain, nausea and fever may have appendicitis or any of a number of other problems. But how does the child's doctor decide whether to schedule an emergency appendectomy to surgically remove a presumably inflamed appendix - a procedure that carries its own risks like any surgery - or wait and observe what could be a ticking time bomb that could rupture and kill the patient in a matter of hours? It's a classic physician's dilemma, but a new study led by the Johns Hopkins Children's Center may ease the pediatrician's problem-solving and parents' anxiety. ...> Full Article

First Case Of Successful Ovarian Tissue Transplantation Between Two, Non-Identical Sisters (8/7/2007)

A woman, whose ovaries had failed due to damage caused by chemotherapy and radiotherapy, has received a successful ovarian transplant from her genetically non-identical sister. The transplant restored her ovarian function, she started to menstruate and, after a year, doctors were able to recover two mature oocytes from her ovaries and fertilise them to produce two embryos. ...> Full Article

Rise of Obesity Exacerbated by 'Social Multiplier' Effects (8/6/2007)

According to a new study in Economic Inquiry, an individual's body weight depends not just on physiology and economic circumstances, but also on average body weight of the population at large. The study is the first to quantitatively model body weight distribution based on the combined outcome of economic, biological and social influences. ...> Full Article

Influence Of A Cancer Inhibitor On A Single DNA Molecule Tracked (8/6/2007)

Researchers in Delft University of Technology's Kavli Institute of Nanoscience have cast new light on the workings of the important cancer inhibitor topotecan. Little had been known about the underlying molecular mechanism, but the Delft scientists can now view the effects of the medicine live at the level of a single DNA molecule. The research has been published online by the journal Nature on 24 June 2007. The lead author of the article, Daniel Koster, received his PhD at TU Delft on Monday 25 June 2007, partly on the results described in the article. ...> Full Article

Handicapping Tuberculosis May Be The Way To A Better Vaccine (8/6/2007)
