A new study from the University of Iowa and published by the Journal of the American Medical Association finds that children with autism spectrum disorder (ASD) are more than twice as likely to suffer from a food allergy than children who do not have ASD.
Antibiotics are most commonly prescribed for acute respiratory infections, although most of these infections are caused by viruses for which antibiotics aren't effective. A new study found that among almost 15,000 outpatients with acute respiratory infections during flu seasons, 41 percent of outpatients were prescribed antibiotics and 41 percent of them had diagnoses for which antibiotics weren't indicated. The results suggest antibiotic overuse remains widespread in the treatment of outpatient acute respiratory infections.
Food and other types of allergies are more likely to be reported in children with autism spectrum disorder (ASD) than in children without ASD but the underlying reasons for this association aren't clear.
Researchers have demonstrated that microbial signatures, the unique microbial make-up of each individual, from the built environment can identify persons involved in crimes occurring in the home, such as burglaries. The research is presented at ASM Microbe, the annual meeting of the American Society for Microbiology, held from June 7-11 in Atlanta, Ga.
Scientists with USDA's Agricultural Research Service (ARS) are developing ways to identify the sources of any potentially harmful bacteria found in the surface waters around Athens, Georgia. The research is presented at ASM Microbe, the annual meeting of the American Society for Microbiology, held from June 7-11 in Atlanta, Ga.
Researchers from Vanderbilt University Medical Center have determined the metabolic pathway that Staphylococcus aureus use to survive in bones. Invasive S. aureus infections frequently occur in the bone and are notoriously resistant to antimicrobial therapy. The research is presented at ASM Microbe, the annual meeting of the American Society for Microbiology, held from June 7-11 in Atlanta, Ga.
Five percent more cardiac infarctions detected and 11 percent fewer patients suffering a relapse. That is the result of a study of more than 80,000 patients in which two cardiac damage markers (conventional troponin and the newer, high-sensitive troponin T) were compared with each other.
A team of researchers form Russia discovered that an increase in the concentration of several substances in oral fluid can serve as the indication of caries development. Using this data they found a way to prevent the disease in its early stages. The study was supported by a grant from the Russian Science Foundation (RSF). The results of the study were published in the EPMA Journal.
Saturn is the second largest planet in our solar system and has a characteristic ring. Japanese researchers have now synthesized a molecular 'nano-Saturn'. As the scientists report in the journal Angewandte Chemie, it consists of a spherical C(60) fullerene as the planet and a flat macrocycle made of six anthracene units as the ring. The structure is confirmed by spectroscopic and X-ray analyses.
A research team led by Prof. ZHENG Hairong from the Shenzhen Institutes of Advanced Technology (SIAT) of the Chinese Academy of Sciences, in collaboration with Prof. LIU Bin from the University of Singapore, reported the first NIR-II fluorescent molecule with aggregation-induced-emission (AIE) characteristics for dual fluorescence and photoacoustic imaging.
During a depressive episode the ability of the brain to form new brain cells is reduced. Scientists of the Ruhr-Universität Bochum examined how this affects the memory with a computational model. It was previously known that people in an acute depressive episode were less likely to remember current events. The computational model however suggests that older memories were affected as well. How long the memory deficits reach back depends on how long the depressive episode lasts.
The Visual Perception and Cognition Laboratory research team at the Toyohashi University of Technology has uncovered a material perception mechanism with which humans discriminate between reflective and transparent materials (mirror and glass). The research team discovered that the brain adeptly utilizes motion of complex reflective and transparent images that appear on object surfaces when distinguishing between mirror and glass. These results can be applied to reproduction technology and measurement systems based on visual perception mechanisms.
A new Portland State University study shows that not all populations of a single, widely spread tree species respond the same to climate change, something scientists will need to consider when making climate change projections.
Scientists led by Rice University and Los Alamos National Laboratory have discovered properties in naturally occurring solution-processed quantum wells that are likely to impact the growing field of low-cost perovskite based optoelectronics. They created a general scaling law that researchers can use to determine how to tune the electronic properties of 2D perovskite-based materials for devices.
A Kaiser Permanente study of nearly 2,500 patients who used high doses of opioids for at least six months showed that reducing their opioid use did not lower their satisfaction with care. The study, 'Satisfaction With Care After Reducing Opioids for Chronic Pain,' was published today in The American Journal of Managed Care.
Global Fishing Watch releases the first-ever 'live' global view of likely transshipping at sea -- a practice that can mask illegal fishing activity, and imagery of night-time fishing and its location, exposing vessels often hiddenfrom other monitoring systems.
Fossils representing two new species of saber-toothed prehistoric predators have been described by researchers from the North Carolina Museum of Natural Sciences (Raleigh, USA) and the Vyatka Paleontological Museum (Kirov, Russia). These new species improve the scientists' understanding of an important interval in the early evolution of mammals -- a time, between mass extinctions, when the roles of certain carnivores changed drastically.
An international team of researchers has made CRISPR technology more accessible and standardized by simplifying its complex implementation in a way that offers a broad platform for off-the shelf genome engineering.
Polymer physicists at the University of Massachusetts Amherst are today reporting the unexpected and previously unknown behavior of a charged macromolecule such as DNA embedded in a charged hydrogel, where it displays what they call a 'topologically frustrated' inability to move or diffuse in the gel, a phenomenon they describe in the current Nature Communications.
An international team of researchers led by the Max Planck Institute for the Science of Human History has analyzed two 3,800-year-old Y. pestis genomes that suggest a Bronze Age origin for bubonic plague. The study, published in the journal Nature Communications, shows that this strain is the oldest sequenced to date that contains the virulence factors considered characteristic of the bubonic plague and is ancestral to the strain that caused the Black Death.
