After brain injury, new astrocytes play unexpected role in healing Posted: 24 Apr 2013 10:27 AM PDT The production of a certain kind of brain cell that had been considered an impediment to healing may actually be needed to staunch bleeding and promote repair after a stroke or head trauma, researchers report.

Functional potential of genes: Pushing the boundaries of transcription Posted: 24 Apr 2013 10:26 AM PDT Like musicians in an orchestra who have the same musical score but start and finish playing at different intervals, cells with the same genes start and finish transcribing them at different points in the genome. For the first time, researchers have described the striking diversity of messenger RNAs (mRNAs) that such start and end variation produces, even from the simple genome of yeast cells. Their findings shed new light on the importance of mRNA boundaries in determining the functional potential of genes.

Chernobyl follow-up study finds high survival rate among young thyroid cancer patients Posted: 24 Apr 2013 10:26 AM PDT More than a quarter of a century after the Chernobyl nuclear disaster, many children and teenagers who developed thyroid cancer due to radiation are in complete or near remission, according to a recent study.

ERs have become de facto psych wards Posted: 24 Apr 2013 09:58 AM PDT Long waits for insurance authorization allowing psychiatric patients to be admitted to the hospital from the emergency department waste thousands of hours of physician time, given that most requests for authorization are ultimately granted. A new study argues that pre-authorization process is akin to health care "rationing by hassle factor."

Link between inherited endocrine tumor syndrome and much-studied cell pathway Posted: 24 Apr 2013 09:58 AM PDT The protein menin suppresses signaling in the much-studied Hedgehog pathway in endocrine organs. Menin mutations lead to increased Hedgehog signaling and cell proliferation. Researchers found that inhibiting proteins in the Hedgehog network using drugs reduces growth of tumors in mice.

Fetuin-B, first identified in the year 2000, is formed in the liver and secreted into the blood stream.

Majority of children readmitted to hospital following stem cell transplant Posted: 24 Apr 2013 05:13 AM PDT Almost two-thirds of children who receive stem cell transplants are readmitted to the hospital within six months, according to new research.

Microscopic dust particles found in underground railways may pose health risk Posted: 24 Apr 2013 05:13 AM PDT New research has found that working or traveling on an underground railway for a sustained period of time could have health implications. Previously published work suggests that working in environments such as steel mills or welding plants, which are rich in airborne metals, like iron, copper and nickel, can have damaging effects on health. However, little research has been done on the effects of working in an underground railway environment - a similarly metal-rich environment.

Malaria parasite protein identified as potential new target for drug treatment Posted: 24 Apr 2013 05:13 AM PDT Scientists have discovered how a protein within the malaria parasite is essential to its survival as it develops inside a mosquito. They believe their findings identify this protein as a potential new target for drug treatments to prevent malaria being passed to humans. The researchers found that when this protein – a transporter responsible for controlling the level of calcium inside cells – is absent during the parasite's sexual reproduction stages inside a mosquito, the parasite dies before developing fully.
