Monitoring scoliosis patients on brace use prevents curve progression, surgery Posted: 08 Jan 2016 05:57 PM PST Bracing often is recommended for adolescents diagnosed with idiopathic adolescent scoliosis, and a spinal curve between 25 and 45 degrees. When worn consistently and as directed, braces have been found to effectively halt or slow further progression of a spinal curve, often preventing surgery. However, experts say that monitoring the use of these braces is key for effective results.

Stir no more: Scientists show that draining speeds up bioassays Posted: 08 Jan 2016 05:09 PM PST Three scientists have proposed a way to speed up common bioassays. Their solution, reminiscent of the magic behind washing machines, could reduce wait times to a fraction of what they once were. Biological assays that once took hours could instead take minutes, they say.

New work on knee cartilage structure to aid better replacements and injury treatments Posted: 08 Jan 2016 10:48 AM PST Fibrocartilage tissue in the knee is comprised of a more varied molecular structure than researchers previously appreciated. New work informs ways to better treat such injuries as knee meniscus tears -- treatment of which are the most common orthopaedic surgery in the United States -- and age-related tissue degeneration, both of which can have significant socioeconomic and quality-of-life costs.

Racial disparity lies at intersection of HIV, Hodgkin lymphoma Posted: 08 Jan 2016 10:43 AM PST Among HIV-positive patients with Hodgkin lymphoma, a new study finds that blacks are significantly less likely than whites to receive treatment for the cancer, even though chemotherapy saves lives.

BRCA1 deficiency increases sensitivity of ovarian cancer cells to auranofin Posted: 08 Jan 2016 10:43 AM PST An anti-rheumatic drug could improve the prognosis for ovarian cancer patients exhibiting a deficiency of the DNA repair protein BRCA1, a study has found. Auranofin is currently undergoing trials for repurposing to treat recurrent epithelial ovarian cancer, which makes up around 90 per cent of diagnosed ovarian cancers.

Breakthrough in early diagnosis of preeclampsia Posted: 08 Jan 2016 10:42 AM PST The ratio of certain messengers in the blood of pregnant women can be used to reliably rule out preeclampsia, and to predict the risk of complications, results from an international multicenter study have demonstrated.

New report finds no significant increase in health risks for 1960s Project SHAD veterans Posted: 08 Jan 2016 10:42 AM PST Veterans who participated in a series of tests during the 1960s known as Project SHAD (Shipboard Hazard and Defense) show no significant increase in adverse health outcomes, specific causes of death, or death rates compared with a similar group of veterans who were not involved in the tests, says a new report.

Postnatal depression linked to challenges in parenting: Could oxytocin be helpful? Posted: 08 Jan 2016 10:42 AM PST Caring for an infant is challenging for any mother -- but especially so for women with postnatal depression, which may lead to adverse effects on child outcomes. Current evidence on postnatal depression and parenting -- including preliminary data on the role of the hormone oxytocin -- is the focus of a new article.

Even children with higher IQs behave better when their sleep apnea is fixed Posted: 08 Jan 2016 10:42 AM PST Many doctors will ask about quality of sleep when children have problems at school, but new research shows it's just as important to pay attention to how high achievers are sleeping.

Beneficial effects of blocking brain inflammation in an experimental model of Alzheimer's Posted: 08 Jan 2016 05:44 AM PST Blocking a receptor in the brain responsible for regulating immune cells could protect against the memory and behavior changes seen in the progression of Alzheimer's disease. It was originally thought that Alzheimer's disease disturbs the brain's immune response, but this latest study adds to evidence that inflammation in the brain can in fact drive the development of the disease. The findings suggest that by reducing this inflammation, progression of the disease could be halted.

Researchers face potential danger from protein particles in the lab Posted: 08 Jan 2016 05:44 AM PST Lewy bodies and Lewy neurites are found in the brains of Parkinson's disease (PD) patients. They consist primarily of fibrils of the protein alpha-synuclein (?-Syn), which self-assembles into fibrils in vitro. If introduced into the human body, these seeds can act as prions and trigger the formation of toxic protein deposits. Because ?-Syn fibrils are often used in research, it is important that they are not accidentally transferred to humans or cell cultures. In a new article, researchers describe three cleaning procedures that effectively remove and disassemble these ?-synuclein seeds.

Exercise DVDs could be psychologically harmful for users, new research shows Posted: 08 Jan 2016 05:37 AM PST Using fitness DVDs to work out at home may seem like a good way to get started on new exercise goals this year, but those DVDs may also include negative imagery and demotivating language.

What lessons have we learned from the 2014 ebola epidemic in West Africa? Posted: 08 Jan 2016 05:37 AM PST An academic has analysed what could have been done differently in the efforts to prevent the Ebola epidemic in 2014. In particular, the review focuses on the limits of patient location and travel mapping as a reason why it was difficult to contain Ebola from spreading. Because nobody anticipated such an expansive epidemic, regional disease protocols were not immediately implemented, he concludes.

'Window of recovery' can reopen after stroke Posted: 07 Jan 2016 03:49 PM PST Using mice whose front paws were still partly disabled after an initial induced stroke, researchers report that inducing a second stroke nearby in their brains let them 'rehab' the animals to successfully grab food pellets with those paws at pre-stroke efficiency.

Certain yoga positions may impact eye pressure in glaucoma patients Posted: 07 Jan 2016 07:52 AM PST Glaucoma patients may experience increased eye pressure as the result of performing several different head-down positions while practicing yoga, according to a new study.
