(Medical Xpress)—People are living longer than ever before, thanks to medical and technological advances. Unfortunately, aging can be associated with a decrease in brain function. This is because, unlike other cells in the body, neurons do not replicate. Neuroscientists in Italy have extended the lives of mouse neurons by injecting them into the brains of longer-lived rats, according to a study published in Proceedings of the National Academy of Sciences. This indicates that neuronal lifespan is not predetermined, but depends on conditions in the microenvironment. http://medicalxpress.com/news/2013-02-genetic-clock-neuron-longevity.html Neuroscience Wed, 27 Feb 2013 11:20:02 EST news281184771 (Medical Xpress)—If you want to read a mouse's mind, it takes some fluorescent protein and a tiny microscope implanted in the rodent's head. http://medicalxpress.com/news/2013-02-tool-minds-mice-video.html Neuroscience Tue, 19 Feb 2013 16:20:01 EST news280513186 Recent research has shown that there are new cells that develop in the heart, but how these cardiac cells are born and how frequently they are generated remains unclear. In new research from Brigham and Women's Hospital (BWH), researchers use a novel method to identify these new heart cells and describe their origins. http://medicalxpress.com/news/2012-12-birth-cardiac-cells.html Cardiology Wed, 05 Dec 2012 13:00:19 EST news273929710 A team led by MIT neuroscientists has developed a way to monitor how brain cells coordinate with each other to control specific behaviors, such as initiating movement or detecting an odor. http://medicalxpress.com/news/2012-10-calcium-reveals-neurons.html Neuroscience Wed, 17 Oct 2012 12:33:45 EST news269695996 Chemicals in the environment that mimic estrogen can strongly influence the development of humans and other animals. New research to be presented at the 2012 International Zebrafish Development and Genetics Conference, held June 20-24 in Madison, Wisconsin, reveals that these substances may act even earlier than previously realized, at the very beginning stages of embryonic development. http://medicalxpress.com/news/2012-06-environmental-estrogens-affect-early-developmental.html Genetics Thu, 21 Jun 2012 17:05:27 EST news259517114 Fear conditioning using sound and taste aversion, as applied to mice, have revealed interesting information on the basis of memory allocation. http://medicalxpress.com/news/2012-06-neurological-basis-memory.html Neuroscience Mon, 18 Jun 2012 13:25:16 EST news259244323 Just as Gotham City uses the Bat Signal to call for Batman's aid, a new tool developed by scientists from the Sanford-Burnham Medical Research Institute in La Jolla, California, should serve as the cellular equivalent for children with glycosylation disorders, sometimes called "CDG syndromes." In a new report appearing online in The FASEB Journal, scientists describe how they used a green fluorescent protein to identify the presence of genes—known and unknown—associated with a wide variety of glycosylation-related diseases. By being able to identify exactly which genes are defective, researchers can develop treatments and therapies to correct the root causes of these diseases rather than merely treating the symptoms. http://medicalxpress.com/news/2012-06-holy-glycosylation-flags-distressed-cells.html Medical research Tue, 12 Jun 2012 17:03:36 EST news258739407 Scientists with the new Children's Research Institute at UT Southwestern Medical Center have identified the environment in which blood-forming stem cells survive and thrive within the body, an important step toward increasing the safety and effectiveness of bone-marrow transplantation. http://medicalxpress.com/news/2012-01-blood-forming-stem-cells-growth.html Medical research Wed, 25 Jan 2012 13:00:01 EST news246709546 Researchers from Mount Sinai School of Medicine have discovered the therapeutic benefit of fetal stem cells in helping the maternal heart recover after heart attack or other injury. The research, which marks a significant advancement in cardiac regenerative medicine, was presented today at the American Heart Association's (AHA) Scientific Sessions 2011 in Orlando, Florida, and is also published in the current issue of Circulation Research, a journal of the AHA. http://medicalxpress.com/news/2011-11-fetal-stem-cells-placenta-maternal.html Cardiology Mon, 14 Nov 2011 17:14:45 EST news240513126 Inspired by earlier successes using gene therapy to correct an inherited type of blindness, investigators from the Perelman School of Medicine at the University of Pennsylvania, are poised to extend their approach to other types of blinding disorders. http://medicalxpress.com/news/2011-06-potential-gene-vector-broaden-treatment.html Medical research Wed, 22 Jun 2011 14:00:05 EST news227966075 Oncolytic viruses quickly infect and kill cancer stem cells, which may provide a treatment for tumors that are resistant to conventional chemotherapy and radiation, particularly pancreatic cancer, according to new research from Memorial Sloan-Kettering Cancer Center in New York. The findings are especially important since pancreatic cancer has a poor prognosis and is difficult to detect and treat at early stages. http://medicalxpress.com/news/2011-05-oncolytic-viruses-effectively-pancreatic-cancer.html Cancer Mon, 09 May 2011 11:36:12 EST news224159739
