In the first study to systematically investigate genome-wide epigenetic differences in a large number of psychosis discordant twin-pairs, research at the Institute of Psychiatry (IoP) at King's College London provides further evidence that epigenetic processes play an important role in neuropsychiatric disease. Published in Human Molecular Genetics, the findings may offer potential new avenues for treatment. http://medicalxpress.com/news/2011-09-twin-reveals-epigenetic-psychiatric-disorders.html Genetics Wed, 21 Sep 2011 10:51:01 EST news235821052 British surgeons said Monday that one-year-old conjoined twins from Sudan were recovering well despite huge odds following four operations to separate the girls' fused heads. http://medicalxpress.com/news/2011-09-conjoined-sudanese-twins-medics.html Other Mon, 19 Sep 2011 10:10:01 EST news235644835 Like DNA, fingerprints are unique to each person or set of identical twins.

Their study of identical twins from the US World War II Twin Registry also found that the more a person smoked, the higher their risk of developing macular degeneration. The study, "Smoking, Dietary Betaine, Methionine, and Vitamin D in Monozygotic Twins with Discordant Macular Degeneration: Epigenetic Implications" published in the journal Ophthalmology on July 1, is the first to look at identical twin pairs in which one twin had early age-related macular degeneration (AMD), and the other had late stage AMD. http://medicalxpress.com/news/2011-07-twin-lifestyle-diet-significantly-macular.html Health Tue, 05 Jul 2011 17:12:57 EST news229104757 (Medical Xpress) -- Disregarding the rules and confrontational behaviours are commonplace with young children and can even arise in the first year of life. For some children, this trend will persist and become a character trait despite their parents’ best efforts to teach them obedience and respect for the rules. For some, it will be a precursor to violent and antisocial behaviors. http://medicalxpress.com/news/2011-06-naughty-children-nature-nuture.html Psychology & Psychiatry Tue, 07 Jun 2011 09:51:13 EST news226659017 A new paper by University of Calgary psychologist Dr. David Hodgins says the proliferation of gambling opportunities around the world, particularly online, is increasing the visibility of gambling disorders and giving access to people who previously had no exposure to gambling opportunities. http://medicalxpress.com/news/2011-05-gambling-problem-exposed-access.html Psychology & Psychiatry Thu, 19 May 2011 03:57:00 EST news224996197 (Medical Xpress) -- Compared with other mothers, women who deliver twins live longer, have more children than expected, bear babies at shorter intervals over a longer time, and are older at their last birth, according to a University of Utah study. http://medicalxpress.com/news/2011-05-twinning-moms-twins-longer.html Health Wed, 11 May 2011 03:41:30 EST news224304056 Years ago, identical twin baby boys received a blood transfusion tainted with HIV.
