Scientists at A*STAR's Genome Institute of Singapore (GIS) have developed a novel technique to precisely monitor and study the evolution of micro-organisms such as viruses and bacteria. This is an extremely important capability as it allows scientists to investigate if new drugs designed to kill them are working, and catch the development of resistance early on. http://medicalxpress.com/news/2013-03-lofreq-ultrafast-microbe-cancer-cell.html Medical research Thu, 07 Mar 2013 07:01:55 EST news281862103 Combining hospital MRIs with the mathematical tool known as network analysis, a group of researchers at UC San Francisco and UC Berkeley have mapped the three-dimensional global connections within the brains of seven adults who have genetic malformations that leave them without the corpus callosum, which connects the left and right sides of the brain. http://medicalxpress.com/news/2013-02-network-analysis-abnormal-brain-responsible.html Neuroscience Thu, 28 Feb 2013 16:20:52 EST news281290843 Biomedical researchers studying aging and cancer are intensely interested in telomeres, the protective caps on the ends of chromosomes. In a new study, scientists at UC Santa Cruz used a novel technique to reveal structural and mechanical properties of telomeres that could help guide the development of new anti-cancer drugs. http://medicalxpress.com/news/2013-01-technique-reveals-dynamics-telomere-dna.html Medical research Thu, 17 Jan 2013 13:27:22 EST news277651637 A research team led by Yuko Okamura-Oho and Hideo Yokota of the RIKEN Advanced Science Institute, Wako, has developed a novel technique for three-dimensional (3D) mapping of gene expression patterns onto brain structures. The technique, known as transcriptome tomography, combines tissue sectioning with microarray technology and produces comprehensive maps of the density and location of gene expression, which have a higher resolution than the maps produced by existing methods. http://medicalxpress.com/news/2013-01-technique-comprehensively-three-dimensional-gene-brain.html Genetics Fri, 11 Jan 2013 07:53:30 EST news277113203 A new study about Human Cytomegalovirus (HCMV), a leading cause of birth defects, reveals how the virus co-opts cells' abilities to repair themselves.

Now Yale stem cell researchers have identified a method they hope one day will help cancer patients undergoing chemotherapy maintain a healthy blood supply, they report in the Oct. 18 issue of the journal Cell Reports. http://medicalxpress.com/news/2012-10-blood-ravages-chemo-treatment.html Medical research Fri, 19 Oct 2012 08:20:05 EST news269851363 The World Health Organization estimates that in 2011 there were 216 million cases of malaria and 34.2 million people living with HIV. These diseases particularly afflict sub-Saharan Africa, where large incidence of co-infection result in high mortality rates. Yet, in spite of this global pandemic, interactions between the parasite that causes malaria, Plasmodium falciparum, and HIV-1 are poorly understood. However, a new video article in JoVE, the Journal of Visualized Experiments, that describes a novel technique to study the interactions between HIV-1 and P. falciparum in cultured human cells, will allow scientists to explore different parameters of co-infection by the two microbes. http://medicalxpress.com/news/2012-08-technique-interactions-malaria-parasite-hiv.html Diseases, Conditions, Syndromes Wed, 15 Aug 2012 12:44:14 EST news264253435 (Medical Xpress) -- Researchers at the University of South Florida (USF) College of Nursing have shown that brief treatments with Accelerated Resolution Therapy (ART) substantially reduce symptoms associated with post-traumatic stress disorder (PTSD) including, depression, anxiety, sleep dysfunction and other physical and psychological symptoms. The findings of this first study of ART appear in an on-line article published June 18, 2012 in the journal Behavioral Sciences. http://medicalxpress.com/news/2012-07-resolution-therapy-significantly-ptsd-symptoms.html Psychology & Psychiatry Fri, 27 Jul 2012 09:10:36 EST news262599029 The only person believed to have been cured of HIV infection through a bone marrow transplant said Tuesday he feels wonderful and is launching a new foundation to boost research toward a cure. http://medicalxpress.com/news/2012-07-hiv.html HIV & AIDS Wed, 25 Jul 2012 04:20:02 EST news262407229 A novel technique for measuring tiny, rapid-fire secretions in the brains and mouthparts of fruit flies (drosophila) is providing insights into the beneficial effects of eating less — information that ultimately could help people suffering from neuromuscular disorders. http://medicalxpress.com/news/2012-07-low-calorie-diet-effects-brain-mouthpart.html Medical research Mon, 16 Jul 2012 13:35:02 EST news261664494 Justin M.

Once these cells are guided to the bone surface by this molecule, the stem cells differentiate into bone-forming cells and synthesize proteins to enhance bone growth. The study, which was published online today in Nature Medicine, used a mouse model of osteoporosis to demonstrate a unique treatment approach that increases bone density and prevents bone loss associated with aging and estrogen deficiency. http://medicalxpress.com/news/2012-02-method-stem-cells-bone-formation.html Medical research Mon, 06 Feb 2012 09:55:56 EST news247744547 Just 24 hours after Lisa Rek sang at her niece's wedding, her husband Brad was driving her to a local hospital. http://medicalxpress.com/news/2011-12-university-hospitals-seidman-cancer-center.html Cancer Thu, 01 Dec 2011 12:20:01 EST news241962293 A team of neuroscientists and anaesthetists, who have been using pioneering techniques to study how the brain regulates the heart, has identified a crucial part of the nervous system whose malfunction may account for an increased risk of death from heart failure.
