The Cause Identified Of LGL Leukemia
Date: May-18-2012LGL leukemia is a relatively rare, malignant blood disease of the mature T-cells and, in many cases, it is related to autoimmune diseases such as rheumatoid arthritis. The pathogenetic mechanism of the disease has been unknown and it has previously been unclear if the disease is an overreaction of the normal defense system or a malignant hematological disease. One of the key symptoms of LGL disease is a low count of white blood cells (neutrophils), which may predispose the patients to life-threatening infections. It was discovered that patients suffering from LGL leukemia have a mutation in...
Experts Recommend Overhaul Of Psychiatry's Diagnostic Manual
Date: May-18-2012The Diagnostic and Statistical Manual of Mental Disorders (DSM), long the master reference work in psychiatry, is seriously flawed and needs radical change from its current "field guide" form, according to an essay by two Johns Hopkins psychiatrists published in the New England Journal of Medicine. "A generation ago it served useful purposes, but now it needs clear alterations," says Paul R. McHugh, M.D., a professor of psychiatry and behavioral sciences at the Johns Hopkins University School of Medicine and co-author of the paper with Phillip R. Slavney, M.D., a professor emeritus in the same...
Using Brain Computer Interface, Paralysed Patients Control Robotic Arms To Reach And Grasp
Date: May-18-2012On April 12, 2011, nearly fifteen years after she became paralyzed and unable to speak, a woman controlled a robotic arm by thinking about moving her arm and hand to lift a bottle of coffee to her mouth and take a drink. That achievement is one of the advances in brain-computer interfaces restorative neurotechnology and assistive robot technology described in the journal Nature by the BrainGate2 collaboration of researchers at the Department of Veterans Affairs, Brown University, Massachusetts General Hospital, Harvard Medical School., and the German Aerospace Center (DLR). A 58-year-old...
Make Or Break For Cellular Tissues
Date: May-18-2012Models developed to study liquids are used to investigate the mechanics of cellular tissues, which could further our understanding of embryonic development and cancer In a study about to be published in EPJ E¹, French physicists from the Curie Institute in Paris have demonstrated that the behaviour of a thin layer of cells in contact with an unfavourable substrate is akin to that of thin fluid or elastic films. Understanding the mechanism by which a thin layer of cells splits into disjointed patches, thus breaking the layer's structural integrity, bears great significance because the human...
Gene Related To Autism, Schizophrenia And Obesity Isolated By Zebrafish Study
Date: May-18-2012What can a fish tell us about human brain development? Researchers at Duke University Medical Center transplanted a set of human genes into a zebrafish and then used it to identify genes responsible for head size at birth. Researchers at Duke University Medical Center transplanted a set of human genes into a zebrafish and then used it to identify genes responsible for head size at birth. Head size in human babies is a feature that is related to autism, a condition that recent figures have shown to be more common than previously reported, 1 in 88 children in a March 2012 study. Head size is...
Unravelling How Locomotion Starts
Date: May-18-2012Scientists at the University of Bristol have shed new light on one of the great unanswered questions of neuroscience: how the brain initiates rhythmic movements like walking, running and swimming. While experiments in the 1970s using electrical brain stimulation identified areas of the brain responsible for starting locomotion, the precise neuron-by-neuron pathway has not been described in any vertebrate - until now. To find this pathway, Dr Edgar Buhl and colleagues in Bristol's School of Biological Sciences studied a small, simple vertebrate: the Xenopus frog tadpole. They found that the...
A Competent, Virtual Exercise Partner Can Boost Motivation And Improve Team Performance
Date: May-18-2012A new study, testing the benefits of a virtual exercise partner, shows that the presence of a moderately more capable cycling partner boosts motivation to stick to an exercise program. The work by Brandon Irwin and colleagues, from Michigan State University in the US, is published online in Springer's journal, Annals of Behavioral Medicine. For many people, lack of motivation is a barrier to achieving both the recommended amount and intensity of exercise. Using the principles of group exercise, which is known to increase people's motivation to stick to an exercise program, the researchers...
Shared Risk Factors For Child Behavior Problems Revealed For U.S., Great Britain
Date: May-18-2012New research from North Carolina State University shows that the United States and Great Britain share common risk factors that increase the likelihood of behavioral problems in children - and that Britain's broader social welfare programs don't appear to mitigate those risks. The researchers - from NC State, California State University Northridge and the University of Illinois (UI) - evaluated data from a 1994 study of children between the ages of five and 13 in the U.S. and a 1991 study of children in the same age range from England, Scotland and Wales. In both societies, researchers found...
Lapatinib Combined With Cetuximab Overcomes Resistance In EGFR-Driven Tumors
Date: May-18-2012Targeted therapies have been studied for years, but recent laboratory research is providing robust clues about drugs that might work better in combination, particularly in treating cancers that have become resistant to therapy. That kind of information is behind a novel clinical trial at Georgetown Lombardi Comprehensive Cancer Center that combines cetuximab and lapatinib. Findings from this phase I study will be presented at the American Society of Clinical Oncology annual meeting in Chicago, June 1st through 5th. Cetuximab works by blocking the epidermal growth factor receptor (EGFR) found...
Positive Survival Trend Seen In Phase I Study Of Temsirolimus, Capecitabine
Date: May-18-2012A phase I clinical trial examining the safety of combining temsirolimus and capecitabine in advanced malignancies suggests the two agents can be given safely to patients. In addition, the Georgetown Lombardi Comprehensive Cancer Center researchers conducting the study in cancer patients whose tumors have resisted multiple treatments say the combination demonstrates "promising evidence" of disease control and should be studied in a phase II trial. Their clinical findings and additional data from the study will be presented at the American Society of Clinical Oncology (ASCO) annual meeting in...
