New SIDS research shows carbon dioxide, inner ear damage may play important role Posted: 25 Oct 2016 09:51 AM PDT Sudden Infant Death Syndrome (SIDS) may be linked to the build up of carbon dioxide and existing inner ear damage according to a new study. Experts say the finding could help researchers understand the sequence of events and risk factors that lead to SIDS deaths.

Researchers use CRISPR to accelerate search for HIV cure Posted: 25 Oct 2016 09:51 AM PDT A newly developed gene-editing system has been used to find gene mutations that make human immune cells resistant to HIV infection.

Scientists root for more cassava research to help meet greater demand for food Posted: 25 Oct 2016 09:48 AM PDT Global food demand is expected to grow by 110 per cent over the next 30 to 35 years, and for many of the poorest people on the planet, particularly in Sub-Saharan Africa, cassava is the most important source of calories. Cassava is also important as a crop that is resistant to climate change, but it has not received the same amount of attention as other staple food crops, say researchers.

Structure of key DNA replication protein solved Posted: 25 Oct 2016 08:46 AM PDT A research team has solved the three-dimensional structure of a key protein that helps damaged cellular DNA repair itself. Investigators say that knowing the chemical structure of the protein will likely help drug designers build novel anti-cancer agents.

Can the brain feel it? The world's smallest extracellular needle-electrodes Posted: 25 Oct 2016 08:44 AM PDT 5-?m-diameter needle-electrodes on 1 mm × 1 mm block modules have now been developed by researchers. This tiny needle may help solve the mysteries of the brain and facilitate the development of a brain-machine interface.

Teenagers influenced by video games with alcohol, smoking content Posted: 25 Oct 2016 08:43 AM PDT Images and references to alcohol and tobacco in popular video games may be influencing UK teens who play the games and the age restriction system is not working, according to a new study.

Sleep loss tied to changes of the gut microbiota in humans Posted: 25 Oct 2016 08:41 AM PDT Curtailing sleep alters the abundance of bacterial gut species that have previously been linked to compromised human metabolic health, results from a new clinical study suggests.

Halloween candy deconstructed: Ingredients of a few popular Halloween candies Posted: 25 Oct 2016 06:30 AM PDT It Halloween time. The costumes, the candy, the candy, the candy, and lots of it. Maybe it's time to forget the calories for a movement and take a look at the ingredients.

More than 50% of Americans now have at least one chronic health condition, mental disorder or substance-use issue Posted: 25 Oct 2016 06:26 AM PDT With the future of US healthcare likely to rest on the next presidency, a new study highlights just how complex the medical needs of many Americans now are.

World’s largest study shows effects of long-term exposure to air pollution and traffic noise on blood pressure Posted: 25 Oct 2016 05:47 AM PDT Long-term exposure to air pollution is linked to a greater incidence of high blood pressure, according to the largest study to investigate the effects of both air pollution and traffic noise by following over 41,000 people in five different countries for five to nine years.

Dieting success may be hardwired into the brain Posted: 25 Oct 2016 05:26 AM PDT Scientists studied the connections between the executive control and reward systems in the brain, and discovered the ability to self-regulate a healthy body weight may be dependent on individual brain structure.

Simple instruction sheet helps patients correctly take regular medications before surgery Posted: 24 Oct 2016 02:06 PM PDT Patients may be more likely to take their regularly prescribed medications for chronic conditions such as diabetes and hypertension correctly before surgery when provided a simple instruction sheet, reveals a study. Taking medication correctly before surgery can improve patient safety and comfort, and reduce day-of-surgery cancellations.

New guidelines published for discontinuing mechanical ventilation in ICU Posted: 24 Oct 2016 01:25 PM PDT New guidelines for discontinuing mechanical ventilation in critically ill adults have been published by researchers. The goal of the guidelines is to help physicians and other health care professionals determine when patients with acute respiratory failure can breathe on their own and to provide clinical advice that may increase the chances for successful extubation.

Women who opt for laughing gas during labor may still get an epidural, study shows Posted: 24 Oct 2016 01:25 PM PDT The majority of women who chose nitrous oxide (laughing gas) to manage labor pain, ultimately decide to have an epidural, according to new research. Investigators found nitrous oxide provided limited pain relief, with patients reporting no change in average pain scores after its use.

Nanofiber coating prevents infections of prosthetic joints Posted: 24 Oct 2016 01:24 PM PDT A novel coating they made with antibiotic-releasing nanofibers has the potential to better prevent at least some serious bacterial infections related to total joint replacement surgery, scientists show in a proof-of-concept study with mice.

Study links small RNA molecule to pregnancy complication Posted: 24 Oct 2016 01:22 PM PDT A family of small RNA molecules affects the development of cells that give rise to the placenta -- an organ that transfers oxygen and nutrients from mother to fetus -- in ways that could contribute to a serious pregnancy complication, researchers report.

Scientists uncover why hepatitis C virus vaccine has been difficult to make Posted: 24 Oct 2016 01:16 PM PDT Researchers have been trying for decades to develop a vaccine against the globally endemic hepatitis C virus (HCV). Now scientists have discovered one reason why success has so far been elusive.

How even our brains get 'slacker' as we age Posted: 24 Oct 2016 01:16 PM PDT Losing the youthful firmness and elasticity in our skin is one of the first outward signs of aging. Now it seems it's not just our skin that starts to sag, but our brains too.

What proportion of cancer deaths are attributable to smoking around the US? Posted: 24 Oct 2016 10:37 AM PDT The proportion of cancer deaths attributable to cigarette smoking varied across the United States but was highest in the South, where nearly 40 percent of cancer deaths in men were estimated to be connected to smoking in some states, according to a new article.

How is health-related quality of life for kids with postconcussion symptoms? Posted: 24 Oct 2016 10:36 AM PDT Children with persistent postconcussion symptoms reported lower overall, physical, emotional, social and school quality of life for at least 12 weeks after concussion than children whose concussion symptoms resolved more quickly, although even those children reported lower school quality of life, according to a new article.

Cytomegalovirus infection relies on human RNA-binding protein Posted: 24 Oct 2016 10:17 AM PDT A new understanding of how cytomegalovirus interacts with host cells provides a new potential therapeutic target, conclude scientists.

Tumor markers can reveal lethality of bladder cancers, guide treatment Posted: 24 Oct 2016 07:42 AM PDT Tumor cells collected during the removal of a cancerous bladder and transplanted into mice with weakened immune systems could help physicians rapidly identify high-risk cancers, determine prognosis and refine the use of biomarkers to personalize care for patients with this common cancer.

New evaluation model delivers improved care for patients with cognitive disorders Posted: 24 Oct 2016 06:59 AM PDT First year data on the effectiveness of a new care model has been published. The work follows a three-step evaluation and management plan from clinicians in Geriatrics, Neuropsychology and Neurology, examines patients referred for evaluation of cognitive complaints based on activities of daily living, demographic information, co-morbid conditions, and medication review.

Brain changes seen in youth football players without concussion Posted: 24 Oct 2016 06:58 AM PDT Researchers have found measurable brain changes in children after a single season of playing youth football, even without a concussion diagnosis, according to a new study.

Fragranced products: Risks for people and profits? Posted: 24 Oct 2016 06:54 AM PDT Over one-third of Americans report health problems -- from asthma attacks to migraine headaches -- when exposed to common fragranced consumer products such as air fresheners, cleaning supplies, laundry products, scented candles, cologne, and personal care products. The same study also found that fragranced products may affect profits, with more than 20% of respondents entering a business, but leaving as quickly as possible if they smell air fresheners or some fragranced product.
