.. Color sensor array helps identify and quanitfy toxic industrial chemicals Imagine a polka-dotted postage stamp-sized sensor that can sniff out some known poisonous gases and toxins and show the results simply by changing colors. Support for the application form and development of this electronic nose originates from the National Institute of Environmental Health Sciences, part of the National Institutes of Health. The brand new technology is talked about in this month’s problem of Nature Chemistry and exemplifies the types of sensors that are becoming developed as part of the NIH Genes, Environment and Wellness Initiative that is basic, fast, inexpensive, and functions by visualizing colors.The analysis also examined drugs that might be useful for treating Takotsubo cardiomyopathy. Some beta blockers, used to treat high blood pressure, angina and heart failure, enhanced or reproduced the features of Takotsubo, giving new insights in to the protective ramifications of these drugs. Levosimendan, a different kind of drug given in heart failure to stimulate the heart without going through the adrenaline receptor pathways, had an advantageous effect.
