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.
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.
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 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.
The latest in a series of congressionally mandated biennial reviews of the evidence of health problems that may be linked to exposure to Agent Orange and other herbicides used during the Vietnam War found sufficient evidence of an association for hypertension and monoclonal gammopathy of undetermined significance (MGUS). The committee that carried out the study and wrote the report, Veterans and Agent Orange: Update 11 (2018), focused on the scientific literature published between Sept. 30, 2014, and Dec. 31, 2017.
Scientists from Bradford warn of increased chemical weapons risk during a period of very rapid scientific change.
A team of physicists and a virologist, led by a scientist at the University of California, Riverside, explains how large virus shells are formed. Their work can also be used also to explain how large spherical crystals form in nature. This understanding may help researchers interrupt viruses' formation, containing the spread of viral diseases.
A team of scientists led by Professor Richard Layfield at the University of Sussex has published breakthrough research in molecule-based magnetic information storage materials.
