Polymerization by chemical vapor deposition (CVD) is a simple method for modifying surfaces by which topologically challenging substrates can be evenly coated with polymers. In the journal Angewandte Chemie, researchers have now introduced the first CVD method for producing degradable polymers. Biomolecules or drugs can be attached by means of special side groups. This introduces new possibilities for applications like the coating of biodegradable implants.
John Wiley & Sons, Inc. will release its first quarter results prior to market open on Wednesday, December 7, 2016.
Wiley today announced the launch of Wiley Spectra Lab Desktop edition and Wiley Spectra Lab Server edition, providing flexible options, enhanced features, and essential tools for any organization managing analytical data. In addition to providing access to the world’s largest collection of 2.3 million curated reference spectra, the Desktop edition allows scientists to build their own knowledge bases. The Server edition takes this one step further, providing everything the desktop has to offer combined with centralized storage and controlled access for the whole organization.
Researchers are actively studying polyhydroxyalkanoates (PHAs), a family of natural polyesters produced by microorganisms that may represent biodegradable and biocompatible substitutes for petroleum-based plastics. For the past 30 years, investigators have been striving to determine the crystal structure of an important enzyme in the production of PHAs-- called PHA synthase-- but without success. Now a team publishing two articles in Biotechnology Journal reports success, while also elucidating mechanisms of the enzyme reaction involved in PHA production.
John Wiley & Sons Inc. (NYSE: JWa and JWb), announced today plans to require ORCID iDs as part of the manuscript submission process for a large number of journals.
Certain medications are considered high risk in elders. In a recent study of 287 individuals ≥65 years who experienced a fall while hospitalized at an urban academic hospital, 62 percent of falls occurred in patients in whom high risk medications had been administered within the 24 hours before the fall.
Light Switch in Autumn Leaves: Yellow chlorophyll decomposition products are environment-responsive photoswitches
Before trees lose their leaves in the winter, they offer us a bright autumnal display of reds, oranges, and yellows. This results from the decomposition of the compound that makes leaves green: chlorophyll. Among the decomposition products are yellow phyllobilins that demonstrate unusual chemical properties. As reported by Austrian scientists in the journal Angewandte Chemie, these compounds act as four-step molecular “switches” that are triggered by light in different ways depending on the environment.
A new study on how people feel the effects of earthquakes illustrates the value that members of the public can add to the scientific research process.
As concerns for the health of current and former players in the National Football League have been mounting, a new report explores the importance of players receiving health care free from conflicts of interest experienced by club doctors and athletic trainers.
In the largest study yet to assess the long-term safety and efficacy of the adjustable transobturator male system (ATOMS) to treat incontinence in men following invasive prostate treatment, the overall success and dry rates were 90% and 64%, respectively, after a median of 31 months.
Having a child with cancer led to income reductions for parents and job discontinuation among mothers in a recent study, even after adjusting for pre-diagnosis sociodemographic factors. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings indicate that childhood cancer affects parents’ income and employment for years after the child’s diagnosis, and that these effects are not equally distributed among mothers and fathers.
Non-alcoholic steatohepatitis (NASH) is a potentially serious liver condition characterized by excess fat in the liver associated with inflammation and scarring. NASH may progress to cirrhosis of the liver and liver cancer, and it can also compromise kidney function.
Feral cats are among the most damaging invasive species worldwide, particularly in Australia where they have caused the extinction of more than 20 mammal species. New work has developed priorities for feral cat research and management, including preventing further extinctions, testing new management tools, and increasing potential for native fauna to coexist with cats.
Exercise Programs May Not Provide Additional Benefits to Usual Physical Therapy Following Total Knee Replacement
In a randomized trial of patients who underwent total knee replacement as a treatment for osteoarthritis, a group program of strengthening and aerobic exercises was not better at alleviating long-term knee pain or overcoming activity limitations compared with usual care, which included physical therapy.
Researchers have found that fat-free mass index, but not body mass index, was a significant predictor of survival in patients with idiopathic pulmonary fibrosis (IPF), a debilitating form of pneumonia. Unlike body mass index, fat-free mass index takes into account the amount of muscle mass a person is carrying.
In a review of published studies addressing patients’ perceptions and factors influencing their reporting of adverse drug reactions, most patients were not aware of reporting systems and others were confused about reporting.
Researchers found modest, yet reliable long-term links between early childhood household smoke exposure and self-reported antisocial behavior in early adolescence.
A new article looks at the potential benefits of a Billion Ton Bioeconomy, a vision to enable a sustainable market for producing and converting a billion tons of US biomass to bio-based energy, fuels, and products by 2030.
A new article summarizes the findings of 16 studies that illustrate how natural regeneration of forests, a low-cost alternative to tree planting, can contribute significantly to forest landscape restoration in tropical regions.
Very little is known about what happens to oil in the ocean after an oil spill and what happens to it once a chemical dispersant has been applied. New research summarizes what is known and what important knowledge gaps remain.
