An Inserm team in Dijon directed by François Ghiringhelli is to publish an article this week in the Nature Medicine review. The article suggests that two chemotherapy drugs frequently used to treat digestive and breast cancers may encourage the development of tumors by modulating the anti-tumoral immune response. http://medicalxpress.com/news/2012-12-chemotherapy-effectiveness-immune.html Immunology Tue, 04 Dec 2012 13:02:28 EST news273848532 Women with polycystic ovary syndrome (PCOS) who are taking combined oral contraceptives have a 2-fold risk of blood clots compared with women without the disorder who take contraceptives, states a study published in CMAJ (Canadian Medical Association Journal). http://medicalxpress.com/news/2012-12-blood-clots-two-fold-women-polycystic.html Medications Mon, 03 Dec 2012 12:00:06 EST news273754625 If you're balding and want your hair to grow back, then here is some good news. A new research report appearing online in The FASEB Journal shows how the FDA-approved glaucoma drug, bimatoprost, causes human hair to regrow. It's been commercially available as a way to lengthen eyelashes, but these data are the first to show that it can actually grow human hair from the scalp. http://medicalxpress.com/news/2012-10-viagra-follow-up-drug-glaucoma-human.html Medications Fri, 26 Oct 2012 12:52:03 EST news270474673 They’ve been repeated for decades, maybe even hundreds of years – so long that even some physicians have ceased to question their accuracy.

Investigators at the Society of Nuclear Medicine's 2012 Annual Meeting presented how stem cell research for the development of new hair follicles can be monitored with an optical imaging technique that uses bioluminescence, the same process that allows fireflies to light up. http://medicalxpress.com/news/2012-06-bioluminescence-imaging-stem-cell-therapy.html Medical research Mon, 11 Jun 2012 14:10:01 EST news258639369 (HealthDay) -- Got hair? If you don't, you might have a higher risk of prostate cancer, a preliminary study suggests. http://medicalxpress.com/news/2012-05-bald-men-higher-prostate-cancer.html Cancer Tue, 22 May 2012 13:30:01 EST news256911309 Researchers from the Perelman School of Medicine at the University of Pennsylvania have identified an abnormal amount a protein called Prostaglandin D2 in the bald scalp of men with male pattern baldness, a discovery that may lead directly to new treatments for the most common cause of hair loss in men. In both human and animal models, researchers found that a prostaglandin known as PGD2 and its derivative, 15-dPGJ2, inhibit hair growth. The PGD2-related inhibition occurred through a receptor called GPR44, which is a promising therapeutic target for androgenetic alopecia in both men and women with hair loss and thinning. The study is published in Science Translational Medicine. http://medicalxpress.com/news/2012-03-inhibitor-male-pattern-baldness-hair-loss.html Medical research Wed, 21 Mar 2012 14:00:10 EST news251555744 Examining the chin and upper and lower abdomen is a reliable, minimally invasive way to screen for excessive hair growth in women, a key indicator of too much male hormone, researchers report. http://medicalxpress.com/news/2011-11-women-chin-abdomen-good-indicators.html Other Wed, 02 Nov 2011 10:52:39 EST news239449938 A new study by researchers at NYU Langone Medical Center has shown that, for the first time, Wnt signaling, already known to control many biological processes, between hair follicles and melanocyte stem cells can dictate hair pigmentation.

Investigators hope the finding ultimately will lead to new treatments for this and less severe forms of excessive hair growth as well as baldness. http://medicalxpress.com/news/2011-06-genetic-mutation-excessive-hair-growth.html Genetics Fri, 03 Jun 2011 12:33:26 EST news226323177 In one of the first studies to look at the population behavior of a large pool of stem cells in thousands of hair follicles – as opposed to the stem cell of a single hair follicle – Keck School of Medicine of USC scientists deciphered how hair stem cells in mice and rabbits can communicate with each other and encourage mutually coordinated regeneration, according to an article published in the April 29 edition of the journal Science. http://medicalxpress.com/news/2011-05-reveals-clues-hair-stem-cell.html Medical research Mon, 09 May 2011 09:31:43 EST news224152258
