'Natural killer' cells keep immune system in balance <http://news.brown.edu/pressreleases/2009/10/immunity>
Researchers from Brown University and McGill University have discovered that the natural killer, or NK cells, help prevent T cells from over-responding when a virus hits. This balance helps prevent T cells, which ordinarily serve the immune system, from causing harm. Details are in the September issue of the Journal of Experimental Medicine.

You must remember this: Scientists develop nasal spray that improves memory <http://www.eurekalert.org/pub_releases/2009-10/foas-ymr100109.php>
Good news for procrastinating students: a nasal spray developed by scientists promises to give late night cram sessions a major boost, if a good night's sleep follows. In a research report featured as the cover story of the October 2009 print issue of the FASEB Journal, these scientists show that a molecule from the body's immune system (interleukin-6) when administered through the nose helps the brain retain emotional and procedural memories during REM sleep.

Scripps research scientists find missing puzzle piece of powerful DNA repair complex <http://www.eurekalert.org/pub_releases/2009-10/sri-srs093009.php>
Researchers at the Scripps Research Institute have found, crystallized, and biologically characterized a poorly defined component of a key molecular complex that helps people to avoid cancer, but that also helps cancer cells resist chemotherapy.

Longer-lived, healthier mice offer promise of drug treatments for age-related diseases <http://www.eurekalert.org/pub_releases/2009-10/wt-lhm092909.php>
Scientists have managed to extend the lifespan of mice by up to a fifth and reduce the number of age-related diseases the animals suffer. The research, which involved blocking a key molecular pathway, mimics the health benefits of reducing calorie intake and suggests that drug treatments for aging and age-related diseases are feasible.

Umbilical cord blood as a readily available source for off-the-shelf, patient-specific stem cells <http://www.eurekalert.org/pub_releases/2009-10/si-ucb092809.php>
Umbilical cord blood cells can successfully be reprogrammed to function like embryonic stem cells, setting the basis for the creation of a comprehensive bank of tissue-matched, cord blood-derived induced pluripotent stem cells for off-the-shelf applications, report researchers at the Salk Institute for Biological Studies and the Center for Regenerative Medicine in Barcelona, Spain.

It's in the bank: Human cord blood reprogrammed into embryonic-like stem cells <http://www.eurekalert.org/pub_releases/2009-10/cp-iit092809.php>
Human umbilical cord blood cells may be far more versatile than previous research has indicated. Two independent studies, published by Cell Press in the Oct. 2 issue of the journal Cell Stem Cell, report that they have successfully reprogrammed human umbilical cord blood cells into cells with properties similar to human embryonic stem cells.

A step toward better brain implants using conducting polymer nanotubes <http://www.ns.umich.edu/htdocs/releases/story.php?id=7335>
Brain implants that can more clearly record signals from surrounding neurons in rats have been created at the University of Michigan. The findings could eventually lead to more effective treatment of neurological disorders such as Parkinson's disease and paralysis.

Cardiac Stem Cell Trial Seeks To Treat Some Heart Attack Patients
Researchers at UCSF Medical Center have begun enrollment for an early-stage clinical trial to evaluate the safety and efficacy of an adult stem cell <http://www.medicalnewstoday.com/info/stem_cell/whatarestemcells.php> therapy for patients who have just experienced their first acute myocardial infarction, or heart attack <http://www.medicalnewstoday.com/articles/151444.php> . The trial is part of a multi-center national study. The cells used, known as mesenchymal stem cells, were obtained from the bone marrow of healthy adult donors. Depending on their location in the body, mesenchymal stem cells give rise to bone, cartilage, fat, muscle and connective tissue.

Drug Companies Called On To Pool HIV Patents <http://www.medicalnewstoday.com/articles/165849.php>
The international medical humanitarian organization Doctors Without Borders/Médecins Sans Frontières (MSF) today called on nine of the world's largest pharmaceutical companies to help accelerate the availability of new treatments for millions of people living with HIV/AIDS, by pooling their patents on a list of key HIV <http://www.medicalnewstoday.com/articles/17131.php> medicines. A patent pool is a mechanism in which a number of patents held by different parties are brought together and made available to others for production or further development. Patent holders receive royalties paid by those using the patents. The mechanism has been instrumental in promoting innovations in the aeronautics and digital telecommunications industries, for example.

FDA Delays Decision On HPV Vaccine Cervarix <http://www.medicalnewstoday.com/articles/165815.php>
FDA for the second time has delayed its decision on British drugmaker GlaxoSmithKline's human papillomavirus vaccine, Cervarix, the Wall Street Journal <http://online.wsj.com/article/SB10001424052748704471504574443370329592880.html> reports. According to the company, FDA did not indicate that the delay was related to reports that a 14-year-old British girl died this week after receiving the vaccine. According to a statement from British health authorities, the girl had an "underlying medical condition" that likely caused her death, and it is "unlikely that the HPV vaccination was the cause of death." The statement added that officials "are awaiting further test results, which will take some time." FDA was scheduled to announce its decision Tuesday but told GSK it would miss the deadline, according to the drugmaker (Whalen, Wall Street Journal, 9/30). FDA does not comment on pending product reviews, an agency spokesperson said (Perrone, AP/Boston Globe <http://www.boston.com/business/healthcare/articles/2009/09/29/fda_delays_ruling_on_glaxo_cervical_cancer_vaccine/> , 9/29).

Abdominal Aortic Aneurysm Repair Outcomes For Seniors Reviewed <http://www.medicalnewstoday.com/articles/165636.php>
A new study published in the Society for Vascular Surgery's October 2009 issue of the Journal of Vascular Surgery reports that the elderly have better operative outcomes when endovascular repair, rather than open surgery, is used to treat an abdominal aortic aneurysm <http://www.medicalnewstoday.com/articles/156993.php> (AAA). Researchers from the University of Wisconsin in Madison and University of Chicago examined data from the Nationwide Inpatient Sample to focus on patients between the ages of 50 and 85 and older who had had endovascular repair (EVAR) or open repair (OAR) to treat AAAs. They found that those between 50 to 64 years of age had an in-hospital operative mortality of 1.2 percent for OAR and 0.3 percent for EVAR.
