(Medical Xpress)—Researchers in Australia have uncovered what they describe as differences in brain behavior for people diagnosed with either bipolar disorder (BP) or borderline personality disorder (BPD). As they describe in their paper published in the journal Molecular Psychiatry, brain scans of people diagnosed with one or the other of the disorders show differences in the ways emotions are processed, leading perhaps to a true biological marker for the two ailments. http://medicalxpress.com/news/2013-04-effort-reveals-differences-brain-mental.html Psychology & Psychiatry Thu, 04 Apr 2013 05:38:14 EST news284272640 (Medical Xpress)—Though learning to read proceeds smoothly for most children, as many as one in 10 is estimated to suffer from dyslexia, a constellation of impairments unrelated to intelligence, hearing or vision that make learning to read a struggle. Now, Northwestern University researchers report they have found a biological mechanism that appears to play an important role in the reading process. http://medicalxpress.com/news/2013-02-biological-marker-dyslexia.html Neuroscience Tue, 19 Feb 2013 17:00:09 EST news280514895 The combination of shortened telomeres, a biological marker of aging associated with cancer development, and elevated depression significantly impacted bladder cancer mortality, according to data presented at the 11th Annual AACR International Conference on Frontiers in Cancer Prevention Research, held here Oct. 16-19, 2012. http://medicalxpress.com/news/2012-10-depression-shortened-telomeres-bladder-cancer.html Cancer Wed, 17 Oct 2012 15:00:06 EST news269704678 Children exposed to diethyl phthalate (DEP) and butylbenzyl phthalate (BBzP)—phthalate chemicals commonly found in personal care and plastic products—have elevated risk of asthma-related airway inflammation, according to researchers at Columbia Center for Children's Environmental Health (CCCEH) at the Mailman School of Public Health. http://medicalxpress.com/news/2012-09-children-exposed-phthalates-elevated-asthma-related.html Immunology Wed, 05 Sep 2012 12:40:38 EST news266067630 (Medical Xpress) -- Scientists have discovered a biological marker that may help to identify which depressed patients will respond to an experimental, rapid-acting antidepressant. The brain signal, detectable by noninvasive imaging, also holds clues to the agent’s underlying mechanism, which are vital for drug development, say National Institutes of Health researchers. http://medicalxpress.com/news/2012-08-brain-id-fast-acting-antidepressant.html Neuroscience Mon, 06 Aug 2012 08:26:28 EST news263460346 A recent study published in Clinical Cancer Research suggests that the protein hVps37A suppresses tumor growth in ovarian cancer. The work, which was funded by the Austrian Science Fund FWF, shows, for the first time, that this protein is significantly reduced in ovarian cancer cells. The scientists also found that this reduction affects a cellular signalling pathway that is associated with the membrane receptor EGFR (Epidermal Growth Factor Receptor). The receptor is considered an important biological marker for the course of the disease and therapy, and also serves as a target for modern treatment of different cancer types. In fact, the cells in which hVps37A synthesis was reduced showed resistance to Cetuximab, an approved substance for inhibition of EGFR activity. http://medicalxpress.com/news/2012-02-tumor-suppressor-gene.html Cancer Mon, 13 Feb 2012 08:04:02 EST news248342629 In a novel imaging study of sleeping toddlers, scientists at the University of California, San Diego Autism Center of Excellence report that a diminished ability of a young brain's hemispheres to "sync" with one another could be a powerful, new biological marker of autism, one that might enable an autism diagnosis at a very young age. http://medicalxpress.com/news/2011-06-weaker-brain-sync-early-autism.html Neuroscience Wed, 22 Jun 2011 12:35:12 EST news227964900 A lymphoma vaccine uniquely tailored for each patient extends disease-free survival by 14 months, with signs of an even better response for patients with a specific biological marker, a team led by scientists at The University of Texas MD Anderson Cancer Center reported today in the online version of Journal of Clinical Oncology. http://medicalxpress.com/news/2011-05-vaccine-disease-free-survival-follicular-lymphoma.html Cancer Tue, 31 May 2011 16:25:41 EST news226077916 (Medical Xpress) -- Low vitamin D levels among women with breast cancer correlate with more aggressive tumors and poorer prognosis, according to a new University of Rochester Medical Center study highlighted this week at the American Society of Breast Surgeons meeting in Washington, D.C. http://medicalxpress.com/news/2011-05-aggressive-breast-tumors-linked-vitamin.html Cancer Mon, 02 May 2011 07:10:01 EST news223537335
