Drug developers need to know the exact chemical structure of the drug and the expected receptor in order to produce the exact chemical reaction we want within the cell. ...
“There’s a ton of point-of-care tests on the market, so what we focus on is how we can do multimodal testing with a single device, on a single card—PCR, chemistry, and serology testing.” The platform is intended for use beyond COVID-19 PCR testing and even beyond medical, with potential for veterinary, ...

Diacetyl is the chemical that imparts the artificial buttery flavor to popcorn and other foods. ...
The method resembles the bioaccumulation OECD 305 dietary test but includes reference chemicals to determine both somatic and gastro‐intestinal biotransformation rates of test chemicals. Somatic biotransformation rate constants for the test chemicals ranged between 0 and 0.38 (SE 0.03) d−1 ...
In vitro biotransformation assays are currently being explored to improve estimates of bioconcentration factors of potentially bioaccumulative organic chemicals in fish. This study compares thin‐film and solvent‐delivery dosing techniques, as well as single vs. multiple chemical dosing for measuring biotransformation rates of selected polycyclic aromatic ...
In this study, adsorption and degradation of four selected PPCPs, metronidazole, tinidazole, caffeine and chloramphenicol, have been investigated in the laboratory using two agricultural soils in China and sediment from Changjiang River. Adsorption tests using a batch equilibrium method demonstrated that adsorption of all tested chemicals in ...
In a simulation study performed in Tor Mancina area (near Rome, Italy), two dangerous substances (formaldehyde and bromine) were tested. Chemical and physical characterisation, nutritive and organic contents, and trace elements presence were also investigated. ...
