YONGIN, South Korea, May 7, 2024 -- GC Genome Corporation, a leading diagnostics company, today announced that it will present the new clinical data of its AI-based liquid biopsy platform on colorectal cancer detection at the 2024 American Society of Clinical Oncology (ASCO) Annual Meeting in...
However, when possible respiratory irritants were evaluated, these agents were predominantly present in only the vaped e-liquid. Both oxidative stress and inflammatory responses were induced by a menthol-flavored but not a tobacco-flavored e-liquid. Thus, chemical signatures differ between unvaped ...
GC/MS based metabolomics: development of a data mining system for metabolite identification by using soft independent modeling of class analogy (SIMCA) Background The goal of metabolomics analyses is a comprehensive and systematic understanding of all metabolites in biological samples. Many useful ...
Computation method With the help of the molecular modeling program Hyperchem7.5 (W. Thiel 2003, HyperChemTM, Release 7.5 Pro 2002), the geometry of the compounds under study has been optimized on the basis of semi-empirical calculations65. Semi-empirical calculations were carried out using the ...
Cells were harvested by filtration, frozen in liquid nitrogen, and kept at -80°C until RNA extraction and purification. RNA was extracted from the cells using a slightly modified version of the traditional hot phenol protocol [24], followed by ethanol precipitation and washing. Briefly, 5 ml ...
The magnitudes and spatial distributions of the simulated liquid cloud effective radii, liquid cloud optical depths, surface downward shortwave radiation, and surface temperature over China for July 2016 are in good agreement with aircraft, satellite, and surface observations. WRF-GC simulations including...
