How Vitamin E Can Help Prevent Cancer

Date: Mar-18-2013
Researchers have identified an elusive anti-cancer property of vitamin E that has long been presumed to exist, but difficult to find. Many animal studies have suggested that vitamin E could prevent cancer, but human clinical trials following up on those findings have not shown the same benefits. In this new work, researchers showed in prostate cancer cells that one form of vitamin E inhibits the activation of an enzyme that is essential for cancer cell survival. The loss of the enzyme, called Akt, led to tumor cell death. The vitamin had no negative effect on normal cells...

Childhood Depression Linked To Cardiac Risks Later In Life

Date: Mar-18-2013
Teens who were depressed as children are far more likely than their peers to be obese, smoke cigarettes and lead sedentary lives, even if they no longer suffer from depression. The research, by scientists at Washington University School of Medicine in St. Louis and the University of Pittsburgh, suggests that depression, even in children, can increase the risk of heart problems later in life. The researchers report their findings March 15 at the annual meeting of the American Psychosomatic Society in Miami, Fla...

'Daughter Aversion' And Contraception Use In Nepal

Date: Mar-18-2013
While poverty and under-education continue to dampen contraception use in Nepal, exacerbating the country's efforts to reduce maternal and child mortality rates, researchers say another, more surprising factor may be more intractable: Deeply held cultural preferences for sons over daughters...

New Structural Insight Into Neurodegenerative Disease

Date: Mar-18-2013
A research team from the Korea Advanced Institute of Science and Technology (KAIST) released their results on the structure and molecular details of the neurodegenerative disease-associated protein Ataxin-1. Mutations in Ataxin-1 cause the neurological disease, Spinocerebella Ataxia Type 1 (SCA1), which is characterized by a loss of muscular coordination and balance (ataxia), as is seen in Parkinson's, Alzheimer's, and Huntington's diseases. SCA1-causing mutations in the ATAXIN1 gene alter the length of a glutamine stretch in the Ataxin-1 protein...

Single Mutations In VCP Gene Implicated In A Number Of Neurodegenerative Diseases

Date: Mar-18-2013
New research, published in Neuron, gives insight into how single mutations in the VCP gene cause a range of neurological conditions including a form of dementia called Inclusion Body Myopathy, Paget's Disease of the Bone and Frontotemporal Dementia (IBMPFD), and the motor neuron disease Amyotrophic Lateral Sclerosis (ALS). Single mutations in one gene rarely cause such different diseases. This study shows that these mutations disrupt energy production in cells shedding new light on the role of VCP in these multiple disorders...

Preconception Health Trends Among Women Of Reproductive Age

Date: Mar-18-2013
A woman's health status before pregnancy is critical for the health and wellbeing of the fetus and mother-to-be. The U.S. Centers for Disease Control and Prevention (CDC) has set Healthy People 2020 national objectives for women of reproductive age, and young women are making important gains toward achieving some of those health goals, while some trends are less encouraging, as reported in a study published in Journal of Women's Health, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available on the Journal of Women's Health* website...

For Children With Hurler's Syndrome, Cord Blood Effective Alternative To Matched Donor Stem Cells

Date: Mar-18-2013
Transplants of blood-forming stem cells from umbilical cord blood may be an effective alternative to transplants of matched donor bone marrow stem cells to treat children with a rare, debilitating disease known as Hurler's syndrome (HS), according to results of a study published online in Blood, the Journal of the American Society of Hematology (ASH). HS is an inherited metabolic disease characterized by the lack of a critical metabolic enzyme (lysosomal α-L-iduronidase) that breaks down long chains of sugar molecules in the body...

Risk Of Smoking Greater In Children Of Divorced Parents

Date: Mar-18-2013
Both daughters and sons from divorced families are significantly more likely to initiate smoking in comparison to their peers from intact families, shows a new analysis of 19,000 Americans. This University of Toronto study, published online this month in the journal Public Health, shows that men who experienced parental divorce before they turned 18 had 48-per-cent higher odds of ever smoking 100 or more cigarettes than men whose parents did not divorce. Women from divorced families were also at risk, with 39-per-cent higher odds of smoking in comparison to women from intact families...

Suppressing The Brain's "Filter" Can Improve Performance In Creative Tasks

Date: Mar-18-2013
The brain's prefrontal cortex is thought to be the seat of cognitive control, working as a kind of filter that keeps irrelevant thoughts, perceptions and memories from interfering with a task at hand. Now, researchers at the University of Pennsylvania have shown that inhibiting this filter can boost performance for tasks in which unfiltered, creative thoughts present an advantage. The research was conducted by Sharon Thompson-Schill, the Christopher H...

Making Headway In Developing A Vaccine For The Leading Infectious Cause Of Congenital Birth Defects

Date: Mar-18-2013
A virus that most people have probably never heard of, yet most of us carry, is the number one infectious cause of congenital birth defects. One in 750 children are born with, or develop, permanent disabilities such as hearing loss or brain damage as a result of CMV (cytomegalovirus) infection in the womb. Major research efforts are underway to combat this invidious disease. Researchers from Cardiff University and the La Jolla Institute, California, have discovered a previously unknown cellular mechanism that could prove critical in creating a CMV vaccine...
