Brain Regions Critical For Social Behavior And Cognition Affected By Gene Defect, Leading To Autism-Like Behavior
Date: Aug-13-2012Scientists affiliated with the UC Davis MIND Institute have discovered how a defective gene causes brain changes that lead to the atypical social behavior characteristic of autism. The research offers a potential target for drugs to treat the condition. Earlier research already has shown that the gene is defective in children with autism, but its effect on neurons in the brain was not known. The new studies in mice show that abnormal action of just this one gene disrupted energy use in neurons...
Blood Test For Alzheimer's Gaining Ground
Date: Aug-13-2012The possibility of an inexpensive, convenient test for Alzheimer's disease has been on the horizon for several years, but previous research leads have been hard to duplicate. In a study to be published in the August 28 issue of the journal Neurology, scientists have taken a step toward developing a blood test for Alzheimer's, finding a group of markers that hold up in statistical analyses in three independent groups of patients...
Boosting Self-Control By Thinking Abstractly
Date: Aug-13-2012Many of the long term goals people strive for - like losing weight - require us to use self-control and forgo immediate gratification. And yet denying our immediate desires in order to reap future benefits is often very hard to do. In a new article in the August issue of Current Directions in Psychological Science, a journal of the Association for Psychological Science, researchers Kentaro Fujita and Jessica Carnevale of The Ohio State University propose that the way people subjectively understand, or construe, events can influence self-control...
Grapes Lowered Blood Pressure, Improved Blood Flow And Reduced Inflammation In Men With Metabolic Syndrome
Date: Aug-13-2012Consuming grapes may help protect heart health in people with metabolic syndrome, according to new research published in the Journal of Nutrition. Researchers observed a reduction in key risk factors for heart disease in men with metabolic syndrome: reduced blood pressure, improved blood flow and reduced inflammation. Natural components found in grapes, known as polyphenols, are thought to be responsible for these beneficial effects. The randomized, placebo-controlled, crossover study, led by principal investigator Dr. Maria Luz Fernandez and Jacqueline Barona, a PhD student in Dr...
Study Finds Factors That Can Shape Divorced Mothers' Co-Parenting Experiences
Date: Aug-13-2012The type of relationship a woman has with her ex-partner is a factor in how the couple shares custody of children, according to a Kansas State University expert on postdivorce and co-parenting relationships...
Nonsurgical Treatment For Uterine Fibroids: Hormone Acting Drugs With Uterine Artery Embolization
Date: Aug-13-2012Women with uterine fibroids larger than 10 cm have a new nonsurgical treatment choice - hormone acting drugs followed by uterine artery embolization, a new study shows. The new treatment option can replace hysterectomy, which leaves women infertile. The study, conducted at the Yonsei University College of Medicine in Seoul South Korea, included 40 women with 10 cm or larger uterine fibroids. Twelve of the women received gonadotropin-releasing hormone (GnRH) agonists to shrink their fibroids before undergoing uterine artery embolization, said Man Deuk Kim, MD, PhD, lead author of the study...
The Making And Unmaking Of Stem-Like, Aggressive Breast Cancer Cells
Date: Aug-13-2012Breast cancers that depend on the hormones estrogen and progesterone are susceptible to treatments targeting these hormones. Take away this dependence and you lose a valuable treatment option. A University of Colorado Cancer Center study published as a featured article in the journal Oncogene shows how progesterone does just this - by suppressing a key microRNA, progestins return breast cancer cells to a stem-cell-like state in which they haven't yet differentiated, and are thus more resistant to chemotherapies and more likely to carry a poor prognosis...
In Children Under 2, Hepatitis A Vaccination Remains Effective For 10 Years
Date: Aug-13-2012Vaccination against the hepatitis A virus (HAV) in children two years of age and younger remains effective for at least ten years, according to new research available in the August issue of Hepatology, a journal of the American Association for the Study of Liver Diseases (AASLD). The study found that any transfer of the mother's HAV antibodies does not lower the child's immune response to the vaccine. The World Health Organization (WHO) estimates that 1.4 million cases of HAV occur worldwide each year...
The UK's First Hypo Awareness Week - Pinpointing The High Cost Of Treating Low Blood Sugar
Date: Aug-13-2012As the first ever national 'Hypo Awareness Week' is staged by NHS Diabetes from Monday 13th to Sunday 19th August, a recent online study in the journal Diabetic Medicine1 has estimated the annual cost of emergency calls for severe hypoglycaemia at £13.6 million in England, with the average cost per emergency call at £263. The one-year retrospective observational study looked at data over a 12 month period. A key finding was that the annual rate of severe hypoglycaemia attended by the emergency services is high in younger age groups (7...
Gender Differences Revealed In The Effects Of Long-Term Alcoholism
Date: Aug-13-2012Researchers from Boston University School of Medicine (BUSM) and Veterans Affairs (VA) Boston Healthcare System have demonstrated that the effects on white matter brain volume from long-term alcohol abuse are different for men and women. The study, which is published online in Alcoholism: Clinical and Experimental Research, also suggests that with abstinence, women recover their white matter brain volume more quickly than men...
