Preterm Birth: Subtle but Important Memory Function Affected

Posted:

A new study has revealed that children born prematurely show differences in a subtle but important aspect of memory: the ability to form and retrieve memories about context, such as what, when, and where something happened. This type of memory is important, but can be missed on the usual set of direct assessments. The new research suggests that it may be valuable to find targeted ways to help strengthen this aspect of memory in children born preterm. The ...

OPD and Day Care Procedures are Expensive - Are They Covered by Insurance?

Posted:

When a person needs an MRI scan which costs approximately Rs. 10,000 will it be covered by your family floater health policy? It is most probably not covered. Diagnostic tests may lead to treatment in the outpatient department (OPD) and many of these procedures which do not require hospitalization are very expensive - it would be wiser to buy a policy which covers OPD treatment. "For an insurance company, the key is whether or not a line of treatment has been applied. ...

Behavioral Inhibition During Infancy Linked to Adolescent Social Anxiety

Posted:

Behavioral inhibition that persists across early childhood is associated with social anxiety in adolescence, but only among youth who were insecurely attached to their parents as infants, according to researchers at the University of Maryland and the National Institute of Mental Health and the University of Waterloo. Infants who react to unfamiliar objects, people and situations by becoming afraid and withdrawing are referred to as having a behaviorally inhibited temperament. ...

Loss of Sirtuin Enzyme Drives Formation of Early Prostate Cancer

Posted:

Mice studies have revealed that loss of one of sirtuin (SIRT1) enzyme drives the formation of early prostate cancer (prostatic intraepithelial neoplasia, PIN). SIRT1 can defend the cell against damage from free radicals. Researchers created a mouse model that lacked SIRT1. Normally SIRT1 proteins help activate a mitochondrial protein called SOD2, in turn activating those proteins to keep free-radical levels in check. When SIRT1 levels diminish, SOD2 is no longer effective ...

Drug Allergies Triggered by Protein Receptor MRGPRX2

Posted:

Researchers from Johns Hopkins and University of Alberta have identified a single protein receptor, MRGPRX2, as the root of painful and dangerous allergic reactions to medications and other substances. Finding a new drug that targets the problematic protein could help smoothen treatment for patients with prostate cancer, diabetes and even HIV. Previous studies have linked reactions (such as pain, itching and rashes at the injection sites of many drugs) to part of the ...

Resisting Cancer Will be Futile

Posted:

Katherine Borden, from University of Montreal's Institute for Research in Immunology and Cancer (IRIC) has evoked Star Trek's Borg in her fight against Cancer. "Cancer cells rapidly evolve a multitude of defense mechanisms to evade the effects of the oncologist's drug arsenal. Unfortunately, clinical strategies to overcome these lag far behind," Borden explained. "This mismatch likely underlies our inability to implement new durable treatment strategies." However, ...

New Approach to Diagnose Blood Clots in Lungs

Posted:

Pulmonary embolisms, the deadly blood clots in the lungs, can be ruled out by a newly identified "sliding scale" model. Researchers from Intermountain Medical Center in Salt Lake City say that it is more accurate than current diagnostic methods. The new model, which factors in a patient's age, more accurately identifies a patient's risk of the often-deadly blood clots and can more easily rule out the need for additional, more invasive tests, helping to reduce unnecessary ...

Photographer Jen Davis has always been comfortable in front as well as behind the camera. Davis began photographing herself in everyday situations, initially choosing images that were "safe and easy" such as hanging out her washing or having a meal with a friend. Just published in a book entitled "11 Years", Davis came up with the idea in 2002 when she was a student. "I was at the beach on a spring break vacation. I guess I hadn't been in a bathing suit for ...

Faulty Stem Cells Found in Duchenne Muscular Dystrophy

Posted:

Mice with a form of Duchenne muscular dystrophy, like human patients, undergo progressive muscle degeneration and accumulate connective tissue as they age. Now, researchers at the Stanford University School of Medicine have found that the fault may lie at least partly in the stem cells that surround the muscle fibers. They've found that during the course of the disease, the stem cells become less able to make new muscle and instead begin to express genes involved ...

Epigenetic changes can activate or repress genes involved in autism spectrum disorders (ASDs) and early brain development, according to biochemists at NYU Langone Medical Center. Mice studies and laboratory experiments have revealed that epigenetic changes removed the blocking mechanism of a protein complex long known for gene suppression, and transitioned the complex to a gene activating role instead. Researchers showed that autism susceptibility candidate gene 2 (AUTS2) ...
