Researchers have found that children exposed to PBDEs in the womb and in early childhood had deficits in attention, cognition and fine motor skills at ages five and seven.Thu, 15 Nov 2012 13:31:31 ESThttp://www.sciencedaily.com/releases/2012/11/121115133146.htmEating more fish could reduce postpartum depressionhttp://www.sciencedaily.com/releases/2012/11/121115133010.htm Low levels of omega-3 may be behind postpartum depression, according to a new review. Women are at the highest risk of depression during their childbearing years, and the birth of a child may trigger a depressive episode in vulnerable women. Postpartum depression is associated with diminished maternal health as well as developmental and health problems for her child.Thu, 15 Nov 2012 13:30:30 ESThttp://www.sciencedaily.com/releases/2012/11/121115133010.htmPotential vaccine strategies to protect babies from respiratory syncytial virushttp://www.sciencedaily.com/releases/2012/11/121115133002.htm Research indicates that vaccinating families could protect young babies against a common winter virus which can be fatal for infants under six months.Thu, 15 Nov 2012 13:30:30 ESThttp://www.sciencedaily.com/releases/2012/11/121115133002.htmStructure of enzyme topoisomerase II alpha unravelled providing basis for more accurate design of chemotherapeutic drugshttp://www.sciencedaily.com/releases/2012/11/121115132903.htm Medical researchers have for the first time described the structure of the active site core of topoisomerase II alpha, an important target for anti-cancer drugs. The type II topoisomerases are important enzymes that are involved in maintaining the structure of DNA and chromosome segregation during both replication and transcription of DNA. One of these enzymes, topoisomerase II alpha, is involved in the replication of DNA and cell proliferation, and is highly expressed in rapidly dividing cancer cells.Thu, 15 Nov 2012 13:29:29 ESThttp://www.sciencedaily.com/releases/2012/11/121115132903.htmNewly discovered enzyme important in the spreading of cancerhttp://www.sciencedaily.com/releases/2012/11/121115132901.htm Enzyme hunters at UiO have discovered the function of an enzyme that is important in the spreading of cancer. Cancer researchers now hope to inhibit the enzyme.Thu, 15 Nov 2012 13:29:29 ESThttp://www.sciencedaily.com/releases/2012/11/121115132901.htmBrain-machine interfaces: How do you differentiate between a mere urge and a deliberate intention?http://www.sciencedaily.com/releases/2012/11/121115132859.htm When a nearby passenger on a train is talking loudly on the cell phone, one may experience an urge to grab the phone away, but may reach for one's set of earplugs instead. The distinction between a spontaneous urge, a deliberate intention, an abstract wish, and the usual compromise between them is generally not a major problem for humans in every day life. But what if brain activity has to be used to give paralyzed patients control over prosthetic devices? Here, a clear differentiation between these different mental states is necessary. Thus, these concepts gain very concrete significance in the field of neurotechnology.Thu, 15 Nov 2012 13:28:28 ESThttp://www.sciencedaily.com/releases/2012/11/121115132859.htmMathematical counseling for all who wonder why their relationship is like a sinus wavehttp://www.sciencedaily.com/releases/2012/11/121115132855.htm Neuroinformaticians have provided a mathematical model for efficient communication in relationships. Love affair dynamics can look like a sinus wave: a smooth repetitive oscillation of highs and lows. For some couples these waves grow out of control, leading to breakup, while for others they smooth into a state of peace and quietness. The ?relationship-sinus? depends on the time partners take to form their emotional reactions towards each other, mathematicians show.Thu, 15 Nov 2012 13:28:28 ESThttp://www.sciencedaily.com/releases/2012/11/121115132855.htmEarly 50s may be key time to reach baby boomers with health messageshttp://www.sciencedaily.com/releases/2012/11/121115132615.htm For baby boomers, the peak interest in health issues comes at about age 51, with a second peak coming near age 65, according to a new study.Thu, 15 Nov 2012 13:26:26 ESThttp://www.sciencedaily.com/releases/2012/11/121115132615.htmGenetics point to serious pregnancy complication, pre-eclampsiahttp://www.sciencedaily.com/releases/2012/11/121115132613.htm New research has revealed a genetic link in pregnant moms - and their male partners - to pre-eclampsia, a life-threatening complication during pregnancy.Thu, 15 Nov 2012 13:26:26 ESThttp://www.sciencedaily.com/releases/2012/11/121115132613.htm
