Oxygen plays a critical role in early neural development brains, particularly before establishment of complete vasculature; however, it has seldom been investigated due to technical limitations. This study uses an vitro human cerebral organoid model with multiomic analysis, integrating advanced microscopies and single-cell RNA sequencing, monitor tissue oxygen tension during development. Results reveal key period between weeks 4 6 elevated intra-organoid tension, altered energy homeostasis,...
Simultaneous measurement of ethanol, acetaldehyde and acetate.
Adsorption-desorption behaviors of polar and nonpolar volatile organic compounds (VOCs), namely, isopropanol nonane, on mesoporous silica were studied using optical reflectance spectroscopy. Mesoporous was fabricated via electrochemical etching silicon subsequent thermal oxidation, resulting in an average pore diameter 11 nm a surface area approximately 493 m2/g. The thickness the porous layer, which is proportional to number adsorbed molecules, measured visible light interferometry. In situ...
Sterilization of devices is important in hospitals, operating theatres, and emergency rooms. Microdialysis allows vivo sampling small molecules used for clinical studies. probes are made soft, flexible, porous polymeric membranes. They have been traditionally disinfected using either ethanol (which fails to eliminate all microbes doesn't satisfy regulatory requirements) or ethylene oxide gas gamma irradiation (that expensive resource-intensive). In this work, three methods microdialysis...
Continuous measurement of the concentrations ethanol and its metabolites, acetaldehyde acetic acid,
Many alcohol-based hand sanitizer products contain toxic ethanol substitutes. In this work, we demonstrate the application of near-infrared spectroscopy for detection methanol and 1- propanol in using partial least square regression (PLSR).
Recent fatalities due to methanol and 1-propanol toxicity in alcohol-based hand sanitizers has led the U.S. Food Drug Administration (FDA) ban 594 different sanitizer brands. The FDA also introduced testing before allowing products enter United States This requirement creates a need for inexpensive, rapid, portable methods measure concentrations sanitizers. Here we study performance of infrared (IR) spectroscopy measuring an sanitizer, compare two spectrometers, Texas Instruments...
Near-infrared spectra of aqueous ethanol solutions different concentrations and optical pathlengths were tested compared two types infrared spectrometers. Optimal operating conditions performance are reported.
