Method-Of-Loci Strategy May Help Depressed People Remember The Good Times
Date: Feb-27-2013New research highlights a memory strategy that may help people who suffer from depression in recalling positive day-to-day experiences. The study is published in Clinical Psychological Science, a journal of the Association for Psychological Science. Previous research has shown that being able to call up concrete, detailed memories that are positive or self-affirming can help to boost positive mood for people with a history of depression. But it's this kind of vivid memory for everyday events that seems to be dampened for people who suffer from depression...
A Step Towards Malaria Transmission Prevention - SHLP1
Date: Feb-27-2013Experts have disabled a unique member of the signalling proteins which are essential for the development of the malaria parasite. They have produced a mutant lacking the ancient bacterial Shewanella-like protein phosphatase known as SHLP1 (pronounced 'shelph'). This mutant is unable to complete its complex life cycle and is arrested in its development in the mosquito. The discovery could help in the design of new drugs to arrest the spread of this killer disease. Targeting SHLP1 SHLP1 is critical to the cellular development of the malaria parasite...
Heart Development Breakthrough Utilises Nottingham Technology
Date: Feb-27-2013Technology developed at The University of Nottingham has been used in a breakthrough study aimed at developing the first comprehensive model of a fully functioning fetal heart. The abdominal fetal ECG device, designed originally by academics in the University's Department of Electrical and Electronic Engineering and on commercial sale throughout the world since 2008 through the University spin-out company Monica Healthcare Ltd, has been used to observe living fetal hearts of babies in their mothers' wombs...
In IVF, Freezing Embryos To Allow Hormone Levels To Reduce Led To Fewer Undersize Infants, Eliminated Preeclampsia
Date: Feb-27-2013Massachusetts General Hospital (MGH) researchers have identified what may be a major factor behind the increased risk of two adverse outcomes in pregnancies conceived through in vitro fertilization (IVF). Two papers published in the journal Fertility and Sterility support the hypothesis that extremely high estrogen levels at the time of embryo transfer increase the risk that infants will be born small for their gestational age and the risk of preeclampsia, a dangerous condition that can threaten the lives of both mother and child...
Epigenetic And Pharmacological Approaches To Lung Repair
Date: Feb-27-2013Lung diseases such as asthma and chronic obstructive pulmonary disease (COPD) are on the rise, according to the American Lung Association and the National Institutes of Health. These ailments are chronic, affect the small airways of the lung, and are thought to involve an injury-repair cycle that leads to the breakdown of normal airway structure and function. For now, drugs for COPD treat only the symptoms. "A healthy lung has some capacity to regenerate itself like the liver," notes Ed Morrisey, Ph.D...
Omega-3 Fatty Acid Supplementation During Pregnancy Reduced Early Preterm Birth, Low Birth Weight
Date: Feb-27-2013University of Kansas researchers have found that the infants of mothers who were given 600 milligrams of the omega-3 fatty acid DHA during pregnancy weighed more at birth and were less likely to be very low birth weight and born before 34 weeks gestation than infants of mothers who were given a placebo. This result greatly strengthens the case for using the dietary supplement during pregnancy. The results are from the first five years of a 10-year, double-blind randomized controlled trial to be published in the April issue of the American Journal of Clinical Nutrition...
Discrimination Against People With Low Socio-Economic Status Evident In Some Family Physicians' Offices
Date: Feb-27-2013Family physicians' offices appear to discriminate against people of low socio-economic status, even when there is no economic incentive to do so under Canada's system of publicly-funded universal health insurance, new research has shown. At the same time, these offices appear to give preference to people with chronic health conditions, according to the research led by Dr. Stephen Hwang of St. Michael's Hospital...
Promising Viral Treatment For Prostate Cancer Without Unpleasant Side Effects
Date: Feb-27-2013A recombinant Newcastle disease virus kills all kinds of prostate cancer cells, including hormone resistant cells, but leaves normal cells unscathed, according to a paper published online ahead of print in the Journal of Virology. A treatment for prostate cancer based on this virus would avoid the adverse side effects typically associated with hormonal treatment for prostate cancer, as well as those associated with cancer chemotherapies generally, says corresponding author Subbiah Elankumaran of Virginia Polytechnic Institute, Blacksburg...
Patients' Fear Of Developing Lymphedema Far Exceeds Risk Following Breast Cancer Treatment
Date: Feb-27-2013Women who have had the lymph nodes under their arm surgically removed during breast cancer treatment are warned to avoid certain practices that can cause lymphedema - a condition that causes chronic, painless swelling in the arm. Now, a new study published in the March issue of the Journal of the American College of Surgeons suggests that the vast majority of women who undergo breast cancer operations worry about developing this complication and that this fear far exceeds their actual risk of getting lymphedema...
'NanoVelcro' Device Enables 'Liquid Biopsies' For Metastatic Melanoma
Date: Feb-27-2013Researchers at UCLA report that they have refined a method they previously developed for capturing and analyzing cancer cells that break away from patients' tumors and circulate in the blood. With the improvements to their device, which uses a Velcro-like nanoscale technology, they can now detect and isolate single cancer cells from patient blood samples for analysis. Circulating tumor cells, or CTCs, play a crucial role in cancer metastasis, spreading from tumors to other parts of the body, where they form new tumors...
