Functional specialization of MITF, TFEB and TFE3 drives radically distinct adaptive gene expression programs in melanoma.

Within cells multiple related transcription factors targeting the same sequences may co-exist, leading to potential regulatory cooperativity, redundancy or competition. Yet the differential roles and biological functions of co-targeting transcription factors is poorly understood. In melanoma, three highly-related transcription factors are co-expressed: The mTORC1-regulated TFEB and TFE3, that are key effectors of a wide range of metabolic and microenvironmental cues; and MITF, that controls melanoma phenotypic identity.

Multistep Removal System of Gaseous Toluene: Adsorption, Electrochemical, and Photolytic Treatments.

A large amount of atmospheric emissions result from various anthropogenic activities worldwide. Given the complexity of volatile organic compounds (VOCs) and their different adsorption capacities, redox potentials, and photolytic properties, an air purification system for the removal of VOCs that combines multiple physical processes was proposed in this study using toluene as an example. These processes include, in the first step, an adsorption treatment (AT) with activated carbon (AC), where toluene adsorption results from the insertion of aromatic rings (nonpolar groups) between the graphitic carbon planes, as demonstrated by the Raman spectroscopy; in the second step, electrochemical treatment (ECT) using TiO|Ti||SS-304 electrodes applying an electric field to accelerate the oxidation of toluene through the production of free radicals (⋅OH), hydroperoxyl radicals and benzyl groups, followed by the rupture of aromatic rings to generate aliphatic compounds and the consequent mineralization to CO, CO, and HO; in the third step, photolytic treatment (PT) with a 254-nm UV lamp for toluene degradation is used, which is influenced by the addition of radicals, such as ⋅OH or ⋅O , to transform toluene into either benzene or phenol.

Evaluation of intra- and inter-rater agreement on ultrasound measurements of dairy cow teats by operators with different experience levels.

Ultrasound is a valuable, non-invasive technique. It allows for detailed examination, precise measurement, and effective monitoring of teats in dairy cows. This study aimed to evaluate the reliability of ultrasound measurements of teats in dairy cows, specifically focusing on intra- and inter-rater agreement between operators with different levels of experience.
