Turning yogurt waste into new products

Posted: 06 Mar 2015 10:25 AM PST

With exploding consumer demand for Greek yogurt, production is up. That's great for food companies' bottom lines, but it also leaves them dealing with a lot more acid whey, a problematic byproduct of the Greek yogurt-making process. Scientists are developing a way to transform this trash into treasure.

New tool for detecting, destroying norovirus

Posted: 06 Mar 2015 08:20 AM PST

Norovirus infection is the most common cause of viral gastroenteritis, or 'stomach flu.' A research team recently produced 'nanobodies' that could be used to better characterize the structural makeup of the virus. They discovered that these nanobodies could detect the virus in clinical stool samples and disassemble intact norovirus particles. Such nanobodies may potentially be used to not only better detect but also treat symptoms of norovirus infection in the clinic.

Gut bacteria may decrease weight loss from bariatric surgery

Posted: 06 Mar 2015 07:26 AM PST

Some patients do not experience the optimal weight loss from bariatric surgery. The presence of a specific methane gas-producing organism in the gastrointestinal tract may account for a decrease in optimal weight loss, according to new research.

Investigational osteoporosis drug, abaloparatide, lowers fracture risk

Posted: 06 Mar 2015 07:25 AM PST

Abaloparatide-SC, an injectable drug being studied for the treatment of postmenopausal osteoporosis, reduces the rate of new spinal fractures by a statistically significant 86 percent and as well as statistically significant reductions in the fracture rate at other parts of the body, a phase 3 clinical trial finds.

High-normal thyroid hormone level in pregnancy may affect fetal brain development

Posted: 06 Mar 2015 07:25 AM PST

A new study finds that not only low but also high maternal thyroid hormone levels during early pregnancy may significantly lower the infant's IQ later in childhood. The study results suggest that the common practice of treating pregnant women who have mild thyroid hormone deficiency may pose unexpected risks to the developing baby's brain.

Onion extract may improve high blood sugar and cholesterol

Posted: 06 Mar 2015 07:25 AM PST

The extract of onion bulb, Allium cepa, strongly lowered high blood glucose (sugar) and total cholesterol levels in diabetic rats when given with the antidiabetic drug metformin, according to a new study.

Posted: 06 Mar 2015 07:24 AM PST

Oncologists praise gene expression profiling tests as a decision-making tool for women with early-stage breast cancer but also have significant reservations.

New study points to better classrooms for children with disabilities

Posted: 06 Mar 2015 06:16 AM PST

A pilot study in 51 North Carolina classrooms shows the effectiveness of a new measure in assessing the quality of practices in inclusive preschools. Not only is the Inclusive Classroom Profile a reliable instrument, researchers say it also reveals the types of inclusive settings that may be best serving preschoolers with disabilities, researchers say.

Researchers connect climate change to food safety

Posted: 06 Mar 2015 04:38 AM PST

Climate change can affect our food safety in a number of ways. In a European study, researchers state that there is often a relationship between long-term changes in temperature and rainfall and vegetable and fruit contamination. For example, flooding may result in increased concentrations of harmful bacteria that can be quickly broken down again by UV light. Similarly, in one region fungi that produce toxins may increase due to global warming, while they decrease in other regions.

New findings on 'key players' in brain inflammation

Posted: 06 Mar 2015 04:38 AM PST

Inflammatory processes occur in the brain in conjunction with stroke and neurological diseases such as Alzheimer's and Parkinson's disease. Researchers have presented new findings about some of the 'key players' in inflammation. In the long term, these findings could lead to new treatments.

Infant growth affected by exposure to environmental pollutants

Posted: 06 Mar 2015 04:37 AM PST

Even though the levels of two environmental pollutants have declined over the last 20 years, they may still have adverse effects on children's development, according to a new study. The researchers found that maternal levels of DDE (indicating the levels to which the fetuses were exposed to in utero) were significantly associated with rapid growth in early life. They also found that levels of PCB153 in milk and the amount transferred through breastfeeding were associated with decreased infant growth and falling below expected growth curves.

Autism detection improved by multimodal neuroimaging

Posted: 06 Mar 2015 04:36 AM PST

Combined measurements of brain anatomy, connectivity and neurochemistry distinguish autism spectrum disorder subjects from controls, scientists say. This multimodal approach is distinct from many previous studies that have used a single neuroimaging measure. While those studies uncovered widespread functional and anatomical brain abnormalities in ASD, the results were not highly consistent, possibly reflecting the complex brain pathology in autism spectrum disorders.

Popular antioxidant likely ineffective, study finds

Posted: 06 Mar 2015 04:36 AM PST

The popular dietary supplement ubiquinone, also known as Coenzyme Q10, is widely believed to function as an antioxidant, protecting cells against damage from free radicals. But a new study finds that ubiquinone is not a crucial antioxidant.
