Eggs of adolescent girls are different from those of adult women
Date: Feb-28-2014Are the eggs produced by adolescent girls the same as the ones produced by adult women? A recent study published in Human Molecular Genetics by Professor Kui Liu from the University of Gothenburg in Sweden shows compelling evidence that there are two completely distinct types of eggs in the mammalian ovary - "the first wave" and "the adult wave".
Analysis of archived mummy reveals murdered young female with Chagas disease
Date: Feb-28-2014Blunt force trauma to the skull of a mummy with signs of Chagas disease may support homicide as cause of death, which is similar to previously described South American mummies, according to a study published in PLOS ONE by Stephanie Panzer from Trauma Center Murau, Germany, and colleagues, a study that has been directed by the paleopathologist Andreas Nerlich from Munich University.For over a hundred years, the unidentified mummy has been housed in the Bavarian State Archeological Collection in Germany.
New way discovered to identify small quantities of circulating tumor cells
Date: Feb-28-2014Beating cancer is all about early detection, and new research from the University of South Carolina is another step forward in catching the disease early. A team of chemists is reporting a new way to detect just a few lurking tumor cells, which can be outnumbered a billion to one in the bloodstream by healthy cells.The researchers have constructed an ultrasensitive nanoprobe that can electrochemically sense as few as four circulating tumor cells, and it doesn't require any enzymes to produce a detectable signal.

Prescribing and reimbursement practices improved in China
Date: Feb-28-2014Pay-for-performance - reimbursing health care providers based on the results they achieved with their patients as a way to improve quality and efficiency - has become a major component of health reforms in the United States, the United Kingdom, and other affluent countries. Although the approach has also become popular in the developing world, there has been little evaluation of its impact. A new study, just released as a Web First by Health Affairs, examines the effects of pay-for-performance, combined with capitation, in China's largely rural Ningxia Province.
New potential for cell research offered by more naturalistic 3D cell cultures
Date: Feb-28-2014Rather than your average bowl of Lucky Charms, these are three-dimensional cell cultures generated by an exciting new digital microfluidics platform, the results of which have been published in Nature Communications this week by researchers at the University of Toronto. The tool, which can be used to study cells in cost-efficient, three-dimensional microgels, may hold the key to personalized medicine applications in the future."We already know that the microenvironment can greatly influence cell fate," says Irwin A.

Interactive virtual world proves to be an effective learning environment
Date: Feb-28-2014Boston University School of Medicine (BUSM) researchers have demonstrated the potential of using a virtual computer environment for distance healthcare education for an international audience that often has limited access to conventional teaching and training.
Better survival after lung cancer diagnosis in women linked to hormone therapy
Date: Feb-28-2014Survival among people with lung cancer has been better for women than men, and the findings of a recent study indicate that female hormones may be a factor in this difference. The combination of estrogen plus progesterone and the use of long-term hormone therapy were associated with the most significant improvements in survival.The study was designed to explore the influence of several reproductive and hormonal factors on overall survival of women with non-small cell lung cancer (NSCLC).
