SIC50: Determining drug inhibitory concentrations using a vision transformer and an optimized Sobel operator.

As a measure of cytotoxic potency, half-maximal inhibitory concentration (IC50) is the concentration at which a drug exerts half of its maximal inhibitory effect against target cells. It can be determined by various methods that require applying additional reagents or lysing the cells. Here, we describe a label-free Sobel-edge-based method, which we name SIC50, for the evaluation of IC50.

Pattern Differentiation of Lateral Elbow Pain in Traditional Chinese Medicine: A Systematic Review.

Background: Traditional Chinese Medicine (TCM) uses a sophisticated diagnostic system called pattern differentiation, which allows for the tailor-made treatment of individuals.

Objective: This study aimed to identify the commonly used TCM patterns for lateral elbow pain (LEP), as well as the clinical features associated with these patterns.

Method: Journal literature in 15 major Chinese and English databases and textbooks from five medical libraries as well as Chinamaxx were reviewed.

Genetic studies of the role of fatty acid and coenzyme A in photocatalytic inactivation of Escherichia coli.

The roles of bacterial cellular components, namely, fatty acid profile and coenzyme A, in photocatalytic inactivation of bacteria were investigated. Escherichia coli BW25113, as a "parental strain", and its isogenic single-gene deletion mutants E. coli JW1081 (fabF(-) mutant) and E.

Photoelectrochemical degradation of Methylene Blue with beta-PbO2 electrodes driven by visible light irradiation.

Beta-PbO2 electrodes were prepared by electro-deposition and characterized by scanning electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, and linear sweep voltammetry. We confirmed pure (beta-PbO2 crystals were on the electrode and it had a high oxygen evolution potential. The photoactivity and photoelectrochemical (PEC) properties of the beta-PbO2 electrode were investigated under visible light irradiation (lambda > 420 nm) for the decolorization of Methylene Blue.

Effective photocatalytic disinfection of E. coli K-12 using AgBr-Ag-Bi2WO6 nanojunction system irradiated by visible light: the role of diffusing hydroxyl radicals.

Urgent development of effective and low-cost disinfecting technologies is needed to address the problems caused by an outbreak of harmful microorganisms. In this work, we report an effective photocatalytic disinfection of E. coli K-12 by using a AgBr-Ag-Bi(2)WO(6) nanojunction system as a catalyst under visible light (lambda >or= 400 nm) irradiation.

Efficient visible-light-induced photocatalytic disinfection on sulfur-doped nanocrystalline titania.

Sulfur-doped titanium dioxide exhibits a strong visible-light-induced antibacterial effect. The new photocatalyst can effectively kill Micrococcus lylae, a common Gram-positive bacterium. The relationship between sulfur concentration and the bactericidal activity of S-doped TiO2 was investigated.

Photocatalytic activity, antibacterial effect, and photoinduced hydrophilicity of TiO2 films coated on a stainless steel substrate.

Transparent TiO2 films on stainless steel prepared by dip coating in a nonionic microemulsions solution have been shown to have much higher photocatalytic activity than those coatings on glass. Fe3+ and Fe2+ ions, diffusing from stainless steel substrate into TiO2 films during high-temperature calcination, behave as dopants to significantly affect the films' photocatalytic activity. An optimum calcination condition, under which the amount of diffused Fe3+ and the ratio of Fe3+ to Fe2+ ions favor the film's photocatalytic reaction, was obtained.
