Guilt Detection Tests Can Be Beaten By Suppression Of Incriminating Memories
Date: May-31-2013New research published by an international team of psychologists has shown that people can suppress incriminating memories and thereby avoid detection in brain activity guilt detection tests. Such tests, which are commercially available in the USA and are used by law enforcement agencies in several countries, including Japan and India, are based on the logic that criminals will have specific memories of their crime stored in their brain...
Longer Treatment For Children With Langerhans Cell Hystiocytosis Improves Survival Rates
Date: May-31-2013A new international study finds that prolonged, intense initial treatment in children with multi-system Langerhans cell histiocytosis (MS-LCH) can achieve survival rates as high as 84 percent - a full 15 percent improvement over the previous clinical trial in this series. The study, LCH-III, is published in Blood, the journal of the American Society of Hematology. It is the third in a series of international randomized clinical trials for LCH that spans twenty years initiated and coordinated by the Histiocyte Society, a group of more than 200 physicians and scientists worldwide...
Mosquitoes' Sense Of Smell Genetically Altered
Date: May-31-2013In one of the first successful attempts at genetically engineering mosquitoes, Howard Hughes Medical Institute (HHMI) researchers have altered the way the insects respond to odors, including the smell of humans and the insect repellant DEET. The research not only demonstrates that mosquitoes can be genetically manipulated using the latest research techniques, but paves the way to understanding why the insect is so attracted to humans, and how to block that attraction. "The time has come now to do genetics in these important disease-vector insects...
Passengers Play Valuable Role Assisting Crew In Common Medical Emergencies On Flights
Date: May-31-2013Medical emergencies during commercial airline travel can be a frightening experience, but most situations are well-treated by other passengers and flight attendants, in collaboration with consulting physicians on the ground. A University of Pittsburgh study published in the New England Journal of Medicine found that doctors, nurses and other medical professionals on the aircraft helped to treat sick fellow passengers in three-fourths of the emergencies studied. Led by Christian Martin-Gill, M.D., M.P.H...
Potential For Blood Test To Diagnose Alzheimer's In Earliest Stage
Date: May-31-2013Blood offers promise as a way to detect Alzheimer's disease at its earliest onset, Mayo Clinic researchers say. They envision a test that would detect distinct metabolic signatures in blood plasma that are synonymous with the disease - years before patients begin showing cognitive decline. Their study was recently published online in the journal PLOS ONE...
Patients With Anaplastic Oligodendroglioma Identified Who May Benefit From Adjuvant PCV
Date: May-31-2013A further report on the results of EORTC trial 26951 indicates that CpG island methylator phenotype (CIMP) status and O 6-methylguanine-DNA methyltransferase (MGMT) promoter methylation as assessed by MGMT-STP27 are the most informative for identifying grade III glioma patients who might benefit from the addition of procarbazine, CCNU and vincristine (PCV) chemotherapy to radiation therapy...
"Cytophilic" Wound Dressing Inspired By Scabs
Date: May-31-2013Human scabs have become the model for development of an advanced wound dressing material that shows promise for speeding the healing process, scientists are reporting. Their study appears in the journal ACS Applied Materials & Interfaces. Shutao Wang and colleagues explain that scabs are a perfect natural dressing material for wounds. In addition to preventing further bleeding, scabs protect against infection and recruit the new cells needed for healing. Existing bandages and other dressings for wounds generally are intended to prevent bleeding and infections...
Best Treatment For High-Risk Low-Grade Glioma Is Still Radiotherapy
Date: May-31-2013In a large, international, randomized trial, initial radiotherapy was compared to temozolomide chemotherapy. A statistically significant difference between the two treatment strategies was not observed for progression-free survival, although radiotherapy was numerically favored. However, molecular tumor characterization may allow the treatment approach to be personalized and one or the other treatment modality to be selected...
Cholesterol-Lowering Nordic Diet
Date: May-31-2013A healthy Nordic diet lowers cholesterol levels, and therefore the risk of cardiovascular disease, a pan-Nordic study where Lund University participated has found. There was also decreased inflammation associated with pre-diabetes. "The subjects who ate a Nordic diet had lower levels of harmful LDL cholesterol and higher levels of "good" HDL cholesterol. The amount of harmful fat particles in the blood also declined," says Lieselotte Cloetens, a biomedical nutrition researcher at Lund University...
Pitt Researchers Find Immune Cells May Play Previously Unrecognized Role In Inflammation In HIV/AIDS
Date: May-31-2013Depleted numbers of a specific type of white blood cell in the immune systems of people infected with HIV/AIDS appear to be associated with increased levels of unchecked and often damaging inflammation in the body, University of Pittsburgh researchers have discovered. The low numbers of white blood cells, known as CD4+CD73+ T cells - named for the expression of certain proteins and enzymes on their surface - persist even when HIV is well-controlled with medications...
