New technique measures antioxidant capacities of citrus juices

The antioxidant activity of citrus juices and other foods is undervalued. A new technique developed by researchers from the University of Granada for measuring this property generates values that are ten times higher than those indicated by current analysis methods. The results suggest that tables on the antioxidant capacities of food products that dieticians and health authorities use must be revised.

WUSM researchers sequence genome of enterovirus D68 samples from patients

Researchers at Washington University School of Medicine in St. Louis have sequenced the genome of enterovirus D68 sampled from patients treated at St. Louis Children's Hospital. Nationwide, the virus has spread rapidly in recent months and caused severe respiratory illness in young children, with some patients requiring hospitalization.

Researchers identify high-speed cellular transport mechanism

Our DNA and its architecture are duplicated every time our cells divide. Histone proteins are key building blocks of this architecture and contain crucial information that regulates our genes. Danish researchers show how an enzyme controls reliable and high-speed delivery of histones to DNA copying hubs in our cells. This shuttling mechanism is crucial to maintain normal function of our genes and prevent disease. The results are published in the journal Nature Communications.

Researchers discover potential treatment for viral infection that causes illnesses in children

Researchers have discovered a potential treatment for a viral infection that causes potentially fatal brain swelling and paralysis in children. The findings also point to possible treatments for related viruses including those that cause "common cold" symptoms.

Supporting cells in the inner ear can help repair damaged sensory hair cells, say researchers

Researchers have found in mice that supporting cells in the inner ear, once thought to serve only a structural role, can actively help repair damaged sensory hair cells, the functional cells that turn vibrations into the electrical signals that the brain recognizes as sound.

Salk scientists discover how brain keeps track of similar but distinct memories

Ever find yourself racking your brain on a Monday morning to remember where you put your car keys? When you do find those keys, you can thank the hippocampus, a brain region responsible for storing and retrieving memories of different environments-such as that room where your keys were hiding in an unusual spot.

Scientists use magnetic levitation to make in vitro lung tissue more realistic

In a development that could lead to faster and more effective toxicity tests for airborne chemicals, scientists from Rice University and the Rice spinoff company Nano3D Biosciences have used magnetic levitation to grow some of the most realistic lung tissue ever produced in a laboratory.

Scientists identify a possible lead in treatment of two childhood leukemia subtypes

Research led by St. Jude Children's Research Hospital scientists has identified a possible lead in treatment of two childhood leukemia subtypes known for their dramatic loss of chromosomes and poor treatment outcomes.

VEGF produced by NPCs plays a strong role in influencing microglial behavior

The brain's key "breeder" cells, it turns out, do more than that. They secrete substances that boost the numbers and strength of critical brain-based immune cells believed to play a vital role in brain health. This finding adds a new dimension to our understanding of how resident stem cells and stem cell transplants may improve brain function.

Maths-based tool can quantify the spread and infectiousness of viruses

Mathematicians have developed a powerful tool to quantify the spread and infectiousness of viruses like the pandemic H1N1 flu strain, which can be used together with modern laboratory techniques to help the healthcare system plan its response to disease outbreaks.

Drug-resistant tuberculosis: an interview with Sven Hoffner

In contrast to drug-susceptible tuberculosis, which can be cured with available drug therapies, drug-resistant, and especially multi-drug resistant, tuberculosis is much more difficult to cure and it takes a much longer time for patients to become non-infectious.

Antisense therapy shows promise in treating toxoplasmosis

A targeted approach to treating toxoplasmosis, a parasitic disease, shows early promise in test-tube and animal studies, where it prevented the parasites from making selected proteins. When tested in newly infected mice, it reduced the number of viable parasites by more than 90 percent, researchers from the University of Chicago Medicine report in the Proceedings of the National Academy of Sciences.

New toxicology testing method requires lesser number of fish

A new way of testing the safety of natural and synthetic chemicals has been developed by scientists with funding from the Biotechnology and Biological Sciences Research Council (BBSRC). Their research, published today in the journal Ecotoxicology, could reduce the number of fish needed to test the toxicity of a range of chemicals including pharmaceuticals and environmental pollutants.
