Researchers from the universities of Granada and Murcia have confirmed the effectiveness of a spray containing 1% malic acid, which greatly improves xerostomy, or dry mouth, caused by anti-depressant drugs. This product, combined with xylitol and fluorides, in a spray format, stimulates saliva production in patients with this illness, thus improving their quality of life. http://medicalxpress.com/news/2013-04-effectiveness-greatly-mouth-sensation-anti-depressants.html Diseases, Conditions, Syndromes Wed, 03 Apr 2013 10:51:31 EST news284205063 Poly (ADP-ribose) polymerase inhibitors may be a novel treatment strategy for patients with cancer that has become resistant to the commonly used chemotherapy drug cisplatin, according to data from a preclinical study published in Cancer Research, a journal of the American Association for Cancer Research. http://medicalxpress.com/news/2013-04-cisplatin-resistant-cancer-cells-sensitive-experimental.html Cancer Wed, 03 Apr 2013 00:20:01 EST news284141891 A 98-year-old researcher argues that, contrary to decades of clinical assumptions and advice to patients, dietary cholesterol is good for your heart – unless that cholesterol is unnaturally oxidized (by frying foods in reused oil, eating lots of polyunsaturated fats, or smoking). http://medicalxpress.com/news/2013-02-lipid-dietary-heart-disease.html Cardiology Wed, 27 Feb 2013 15:01:31 EST news281199666 (Medical Xpress)—A new Australian study led by Professor Susan Clark from Sydney's Garvan Institute of Medical Research shows that large regions of the genome – amounting to roughly 2% – are epigenetically activated in prostate cancer. http://medicalxpress.com/news/2012-12-cancer-overturns-current-gene.html Cancer Tue, 18 Dec 2012 16:06:03 EST news275069088 Children with persistent and drug-resistant seizures treated with the high-fat, low-carbohydrate ketogenic diet may get an added therapeutic benefit from periodic fasting, according to a small Johns Hopkins Children's Center study. http://medicalxpress.com/news/2012-12-fasting-benefit-patients-epilepsy.html Medical research Fri, 07 Dec 2012 03:00:01 EST news274070450 Scientists at Dana-Farber Cancer Institute have isolated a previously unknown protein in muscles that spurs their growth and increased power following resistance exercise.

There is currently no cure for this disease. Many candidate drugs fail because they also target proteins essential to life. This discovery from Leuven could form a target for a treatment against Alzheimer's disease with fewer side effects and that suppresses the very first symptoms of the disease. This research will be published in the leading journal Nature Medicine. http://medicalxpress.com/news/2012-12-pathway-treatment-alzheimer-disease.html Alzheimer's disease & dementia Mon, 03 Dec 2012 12:15:45 EST news273759332 Analysis of specific biomarkers in a cerebrospinal fluid sample can differentiate patients with Alzheimer's disease from those with other types of dementia.
