Trend: Consumers experiment with transcranial direct current stimulation (tDCS) with no regulatory oversight

— DIY tDCS device: Four 9-volt batteries and sticky self-adhesive electrodes, connected by a circuit board. Courtesy of Matt Herich Students Zap Their Brains For a Boost, For Better Or Worse (NPR): “Last October, Matt Herich was listening to the news while he drove door to door delivering pizzas. A story came on the radio about a technology that sends an electric current through your brain to possibly make you better at some things — moving, remembering, learning. He was fascinated. The neurotechnology is called transcranial direct current stimulation, or tDCS for short. At its simplest, the method involves a device that uses little more than a 9-volt battery and some electrodes to send a low-intensity electrical current to a targeted area of the brain, typically via a headset…Although researchers see possibilities for tDCS in treating diseases and boosting performance, it’s still an exploratory technology, says Mark George, editor-in-chief of Brain Stimulation, a leading journal on neuromodulation. And leading experts have warned against at-home use of such devices… When Herich finished his shift delivering pizzas, he raced home and began googling. He found a thriving community on Reddit and other online forums dedicated to discussing ways to self-administer tDCS…Herich is not alone — beyond the DIY neurostimulation community, companies are cashing in on the phenomenon, offering brain stimulation kits and ready-to-wear heads...

Publication date: Available online 21 January 2020Source: Enzyme and Microbial TechnologyAuthor(s): Hyunjun Choe, Minsun Cha, Jon D. StewartAbstractSerine palmitoyltransferase (SPTase), the first enzyme of the sphingolipid biosynthesis pathway, produces 3-ketodihydrosphingosine by a Claisen-like condensation / decarboxylation reaction of L-Ser and palmitoyl-CoA (n-C16-CoA). Previous structural analysis of Sphingomonas paucimobilis SPTase (SpSPTase) revealed a dynamic active site loop (RPPATP; amino acids 378 - 383) in which R378 (underlined) forms a salt bridge with the carboxylic acid group of the PLP : L-Ser external ald...

In this study, platinum electrodes were fabricated on the bio-based poly(ethylene terephthalate) (Bio-PET) substrates for the development of flexible electrochemical sensors for the detection of Parkinson's disease biomarkers. Dopamine was detected by voltammetric measurements, displaying a 3.5 × 10−5 mol L−1 to 8.0 × 10−4 mol L−1 linear range with a limit of detection of 5.1 × 10−6 mol L−1. Parkinson's disease protein 7 (PARK7/DJ-1) was successfully detected by electrochemical impedance spectroscopy after elec...
