Surfactant-rich aqueous media are common in natural environments. The sea surface microlayer and sea spray droplets are good examples and are also frequently markedly enriched in organic pollutants. This study focuses on the degradation kinetics of organic pollutants initiated by the hydroxyl radical in such surfactant-rich environments.

This study developed heterogeneous catalysts composed of ZnO and CeO supported on H-ZSM-5 for the direct conversion of methane (CH) and carbon dioxide (CO) into acetic acid. The acid-base and electronic properties were modulated through oxide impregnation and reduction, aiming to create active sites capable of simultaneously activating both reactants. The samples were characterized by XRD, N physisorption, HRTEM/EDS, NH-TPD, CO-TPD, TPR, FTIR, XPS, CO-DRIFTS, and TGA, and tested in a batch reactor at 300 °C and 10 bar.

Macroautophagy/autophagy is an evolutionarily conserved process through which cells degrade cytoplasmic substances via autophagosomes. During the initiation of autophagosome formation, the ULK/Atg1 complex serves as a scaffold that recruits and regulates downstream ATG/Atg proteins and ATG9/Atg9-containing vesicles. Despite the essential role of the ULK/Atg1 complex, its components have changed during evolution; the ULK complex in mammals consists of ULK1 (or ULK2), RB1CC1, ATG13, and ATG101, whereas the Atg1 complex in the yeast lacks Atg101 but instead has Atg29 and Atg31 along with Atg17.

Background: Despite promising preclinical results, remote limb ischemic postconditioning efficacy in human stroke treatment remains unclear, with mixed clinical trial outcomes. A potential reason for translational difficulties could be differences in circadian rhythms between nocturnal rodent models and diurnal humans.
Methods: Male C57BL/6J mice were subjected to transient focal cerebral ischemia and then exposed to remote postconditioning during their active or inactive phase and euthanized at 24 hours and 3 days.

Purpose: To evaluate the feasibility of abbreviated liver magnetic resonance imaging (AMRI) with a second-shot arterial phase (SSAP) image for the viability of treated hepatocellular carcinoma (HCC) after non-radiation locoregional therapy (LRT).
Methods: We retrospectively enrolled patients with non-radiation LRT for HCC who underwent the modified gadoxetic acid-enhanced liver MRI protocol, which includes routine dynamic and SSAP imaging after the first and second injection of gadoxetic acid, respectively (6 mL and 4 mL, respectively), and an available reference standard for tumor viability in the treated HCC between March 2021 and February 2022. Two radiologists independently reviewed the full-protocol MRI (FP-MRI) and AMRI with SSAP.
