Microneedles able to draw relatively large amounts of interstitial fluid -- a liquid that lurks just under the skin -- opens new possibilities. Previously, microneedles -- tiny, hollow, stainless steel needles -- have drained tiny amounts of interstitial fluid needed to analyze electrolyte levels but could not draw enough fluid to make more complicated medical tests practical. The new method's larger draws could be more effective in rapidly measuring exposure to chemical and biological warfare agents as well as diagnosing cancer and other diseases.
Monoamine oxidase inhibitors are potential drug candidates within therapeutics of different neuropsychological and neurodegenerative disorders including anxiety, depression and Parkinson's disease. Our findings revealed a good correlation between experimental MAO inhibition and docking score by computational studies. Notably, the compounds with remarkable MAO inhibitory potential were also observed as potential antioxidants.
Researchers from the U.S. Army and top universities discovered a new way to get more energy out of energetic materials containing aluminum, common in battlefield systems, by igniting aluminum micron powders coated with graphene oxide.
America lost 20,360 children and teens in 2016 -- 60 percent of them to preventable injuries, a new study shows. But while death rates from the top cause -- motor vehicle crashes -- have declined steadily since 1999, rates from the second-leading cause -- firearms -- have gone up. It's the first time all causes of child and adolescent death have been tallied by both mechanism and intent.
A team of researchers has developed an algorithm for predicting the effect of an external electromagnetic field on the state of complex molecules. The new algorithm, presented in a paper in The Journal of Chemical Physics, enables researchers to look inside large polyatomic molecules, observe and potentially control electron motion therein.
Researchers using magnetic signals have found unique 'fingerprints' on steel, which could help to verify weapons treaties and reduce the use of counterfeit bolts in the construction industry.
To help determine if the descendants of Gulf War and post-9/11 veterans are at risk for health effects resulting from the service members' exposure to toxicants during deployment, a new report from the National Academies of Sciences, Engineering, and Medicine recommends the creation of a health monitoring and research program (HMRP).
Researchers and cybersecurity experts have begun to examine ways to mitigate the risk of cyberattacks in medical imaging before they become a real danger.
Researchers report that 27 percent of people 65 and older own one or more firearms, and 37 percent live in a home with a firearm present. One study of patients with dementia or related mental health issues revealed 18 percent lived in a home with one or more firearms. Of that group, 37 percent had delusions and 17 percent had documented hallucinations.
Researchers at the University of Illinois at Urbana-Champaign have developed a stamp-sized sensor that can detect trace amounts of certain chemical warfare agents, such as sarin, within minutes. The research is published in ACS Omega.
