Raising hopes for cell-based therapies, UC San Francisco researchers have created the first functioning human thymus tissue from embryonic stem cells in the laboratory. The researchers showed that, in mice, the tissue can be used to foster the development of white blood cells the body needs to mount healthy immune responses and to prevent harmful autoimmune reactions. http://medicalxpress.com/news/2013-05-stem-cell-based-strategy-boosts-immune-mice.html Immunology Thu, 16 May 2013 12:00:03 EST news287923006 (HealthDay)—Oral melatonin does not improve appetite, weight, or quality of life for patients with cachexia due to advanced cancer, according to research published online Feb. 25 in the Journal of Clinical Oncology. http://medicalxpress.com/news/2013-03-oral-melatonin-effect-appetite-advanced.html Cancer Sat, 16 Mar 2013 06:13:44 EST news282633217 Children with brain lesions suffered before or around the time of birth are able to use gestures – an important aspect of the language learning process– to convey simple sentences, a Georgia State University researcher has found. http://medicalxpress.com/news/2013-02-children-brain-lesions-gestures-important.html Psychology & Psychiatry Wed, 20 Feb 2013 12:01:23 EST news280584076 Today, mothers of newborns find themselves confronting a common dilemma: Should they let their babies "cry it out" when they wake up at night? Or should they rush to comfort their crying little one? http://medicalxpress.com/news/2013-01-babes-notion-infants.html Psychology & Psychiatry Wed, 02 Jan 2013 15:25:00 EST news276362688 Results of a new study by researchers at Columbia University's Mailman School of Public Health indicate that a developmental pattern of impulsiveness in young males is linked with gambling problems in late adolescence. Respondents considered to be in the high impulsivity track as early as first grade doubled the odds of meeting criteria for at-risk/problem gambling, and tripled the odds of meeting criteria for problem gambling. The study is the first to link a developmental pattern of impulsivity—defined as a tendency to make rush decisions without carefully considering potential negative consequences—and late-adolescent gambling. Findings appear online in the journal Addiction. http://medicalxpress.com/news/2012-11-impulsivity-grade-problem-gambling-late.html Addiction Tue, 20 Nov 2012 13:06:50 EST news272639197 By the time our children reach kindergarten their learning and developmental patterns are already taking shape, as is a trajectory for their future health. Now, for the first time, scientists have amassed a large collection of research that looks "under the skin", to examine how and why experiences interact with biology starting before birth to affect a life course. http://medicalxpress.com/news/2012-10-field-developmental-neuroscience-early-years.html Neuroscience Mon, 08 Oct 2012 15:00:15 EST news268911961 Researchers at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center have unveiled how and why the public perceives some magic tricks in recent studies that could have real-world implications in military tactics, marketing and sports. http://medicalxpress.com/news/2012-05-barrow-magic-discoveries.html Neuroscience Tue, 22 May 2012 17:40:00 EST news256927192 A new supplement in the journal Cancer outlines an innovative model to address a wide range of physical issues faced by women with breast cancer and offers hope for improved function and full participation in life activities for patients through rehabilitation and exercise. A panel of experts proposes a prospective surveillance model (PSM) that could reduce the incidence and severity of breast cancer treatment-related physical impairments. The model was developed over the past year by a panel of internationally known experts, with the support of the American Cancer Society and input from national healthcare professional organizations and advocacy groups. http://medicalxpress.com/news/2012-04-outlines-breast-cancer.html Cancer Tue, 10 Apr 2012 12:26:04 EST news253279544 (HealthDay) -- Six longitudinal developmental trajectories have been identified among children with autism, with significant heterogeneity seen in developmental pathways within these trajectories, according to a study published online April 2 in Pediatrics. http://medicalxpress.com/news/2012-04-developmental-trajectories-idd-children-autism.html Autism spectrum disorders Mon, 02 Apr 2012 14:10:01 EST news252589850 Patterns of brain development in the first two years of life are distinct in children who are later diagnosed with autism spectrum disorders (ASDs), according to researchers in a network funded by the National Institutes of Health. The study results show differences in brain structure at 6 months of age, the earliest such structural changes have been recorded in ASDs. http://medicalxpress.com/news/2012-02-variation-brain-infants-autism.html Autism spectrum disorders Wed, 22 Feb 2012 09:50:01 EST news249125690
