MS researchers study predictors of employment status Posted: 31 Jan 2014 08:08 PM PST Researchers have studied MS measurement tools for their effectiveness in predicting employment status. They compared the Expanded Disability Status Scale, the Multiple Sclerosis Functional Composite, the Paced Auditory Serial Addition Task, and the Symbol Digit Modalities Test, and found the SDMT effective in differentiating employed from unemployed.

New links found between sleep duration, depression Posted: 31 Jan 2014 08:08 PM PST A genetic study of adult twins and a community-based study of adolescents both report novel links between sleep duration and depression. A study of 1,788 twins is the first to demonstrate a gene by environment interaction between self-reported habitual sleep duration and depressive symptoms. Another study of 4,175 individuals between 11 and 17 years of age is the first to document reciprocal effects for major depression and short sleep duration among adolescents using prospective data.

Fruit flies reveal normal function of gene mutated in spinocerebellar ataxia type 7 Posted: 31 Jan 2014 08:07 PM PST Disruptive clumps of mutated protein are often blamed for clogging cells and interfering with brain function in patients with the neurodegenerative diseases known as spinocerebellar ataxias. But a new study in fruit flies suggests that for at least one of these diseases, the defective proteins may not need to form clumps to do harm.

Retrieval practice improves memory in severe traumatic brain injury, researchers demonstrate Posted: 31 Jan 2014 10:08 AM PST Researchers have shown that retrieval practice can improve memory in individuals with severe traumatic brain injury. Despite the small sample size, it was clear that retrieval practice was superior to other learning strategies in this group of memory-impaired individuals with severe traumatic brain injury.

Gardening provides high-to-moderate physical activity for children Posted: 31 Jan 2014 10:08 AM PST The metabolic cost of 10 gardening tasks was measured in children to determine associated exercise intensities. The children performed the tasks while wearing a portable telemetric calorimeter and a heart rate monitor to measure oxygen uptake and heart rate. Results showed digging and raking to be high-intensity, while the other activities were determined to be moderate-intensity. The data can facilitate the development of garden-based exercise programs for children that promote health and physically active lifestyles.

Potential biomarkers for diagnosis of Alzheimer's disease Posted: 31 Jan 2014 10:07 AM PST Researchers identify abnormal expression of genes, resulting from DNA relaxation, that can be detected in the brain and blood of Alzheimer's patients.

Autistic brains create more information at rest, study show Posted: 31 Jan 2014 10:06 AM PST New research finds that the brains of autistic children generate more information at rest – a 42% increase on average.

Protocol developed to harvest mouse cell lines for melanoma research Posted: 31 Jan 2014 10:06 AM PST Researchers have developed a protocol that permits cells harvested from melanoma tumors in mice to grow readily in cell culture.

New study finds no reason to replace fructose with glucose Posted: 31 Jan 2014 05:35 AM PST Researchers have found there is no benefit in replacing fructose, the sugar most commonly blamed for obesity, with glucose in commercially prepared foods.

Discovery May Lead to New Drugs for Osteoporosis Posted: 30 Jan 2014 03:53 PM PST Scientists have discovered what appears to be a potent stimulator of new bone growth. The finding could lead to new treatments for osteoporosis and other diseases that occur when the body doesn't make enough bone.

Immune drug helps patients with frequently replapsing kidney disease Posted: 30 Jan 2014 03:53 PM PST A specific immune drug could help patients forgo toxic standard treatments that are often ineffective when dealing with frequently relapsing kidney disease.

HPV study: Does vaccinating one sexual partner also benefit the other? Posted: 30 Jan 2014 12:28 PM PST A new study will examine whether vaccinating only one partner in a couple against the human papillomavirus (HPV) can help prevent transmission of HPV to the unvaccinated partner.

Pre-surgical drug may ease recovery, reduce pain for kids Posted: 30 Jan 2014 12:28 PM PST A new evidence review found that administering a drug called clonidine before surgery may be a good alternative for controlling post-surgical pain and help reduce a child's anxiety after surgery.

Epigenetic alterations may contribute to age-related breast cancer risk Posted: 30 Jan 2014 12:28 PM PST Age is a key risk factor for breast cancer. A recent study examines the connection between cancer and the aging process to see if epigenetic DNA alterations might contribute to age-related increases in breast cancer risk.

Protein serves as natural boost for immune system's fight against infection, tumors Posted: 30 Jan 2014 11:12 AM PST The development of DNA-based vaccines with cytokine adjuvants has emerged as particularly promising for inducing antiviral and anti-tumor, cell-mediated immune responses. The protein IL-33 boosts the immune system of a human papilloma virus animal model of cancer.

Cell membrane model studied as future diagnostic tool Posted: 30 Jan 2014 10:31 AM PST Researchers have used a laboratory model of a simplified cell membrane to accurately detect and measure a protein associated with a serious gynecological disease, bacterial vaginosis, at extraordinarily low concentrations.

Zebra fish fins provide insight into bone regeneration Posted: 30 Jan 2014 10:31 AM PST Biologists say they have opened the window on the natural process of bone regeneration in zebra fish, and that the insights they gained could be used to advance therapies for bone fractures and disease.

Real-time video feedback could improve effect of core stabilization exercise in stroke patients Posted: 30 Jan 2014 10:30 AM PST About 80% of stroke survivors experience hemiparesis, which causes weakness or the inability to move one side of the body. Core stabilization exercise to improve postural stability and independent walking in chronic hemiparetic stroke patients could be enhanced by real-time video feedback, report researchers.

FDA approves new MS treatment regimen Posted: 30 Jan 2014 10:30 AM PST Global research results will immediately change the treatment regimen of millions of multiple sclerosis patients around the world.

Some lung diseases reversed in mice by coaxing production of healthy cells Posted: 30 Jan 2014 09:16 AM PST Introducing proteins that direct lung stem cells to grow the specific cell types needed to repair lung injuries could lead to new ways to treat some lung diseases, according to research published.

Women with mental health disability may face four-fold risk of abusive relationship: Study Posted: 30 Jan 2014 09:16 AM PST Women with a severe mental health-related disability are nearly four times more likely to have been a victim of intimate partner violence than those without a disability, according to a new study.

How DNA damage affects Golgi -- the cell's shipping department Posted: 30 Jan 2014 09:16 AM PST In studying the impact of DNA damage on the Golgi, a research team has discovered a novel pathway activated by DNA damage, with important consequences for the body's cellular response to chemotherapy.

Two separate molecular profiles of invasive bladder cancer, genomic analysis reveals Posted: 30 Jan 2014 09:13 AM PST In the second-ever whole-genome analysis in bladder cancer, researchers found two distinct patterns of genetic alteration in tumors and identified a potential target.

'Attention on the flight deck:' What doctors can learn from pilots about communication Posted: 30 Jan 2014 08:09 AM PST With the introduction of a "third party" into the exam room -- the computer that powers electronic medical records -- communication between physician and patient has become more complex. A new study explores the role this technology plays in the doctor-patient relationship.
