The biological clock in eukaryotes controls daily rhythms in physiology and behavior. It displays a complex organization that involves the molecular transcriptional clock and the redox oscillator which may coordinately work to control cellular rhythms. The redox oscillator has emerged very early in evolution in adaptation to the environmental changes in O levels and has been shown to regulate daily rhythms in glycerolipid (GL) metabolism in different eukaryotic cells.

Local necrosis is one of the serious effects caused by envenomation, primarily induced by snake venoms from the Viperidae family through the direct action of components collectively denominated as myotoxins, including the phopholipase A-like (PLA-like) toxins. Considering the limitations of antivenoms in preventing the rapid development of local tissue damage caused by envenomation, the use of small molecule therapeutics has been suggested as potential first-aid treatments or as adjuvants to antivenom therapy.

Materials And Methods: 165 questions from the CBR annual resident assessment (2018, 2019, and 2022) were presented to ChatGPT. For statistical analysis, the questions were divided by the type of cognitive skills assessed (lower or higher order), by topic (physics or clinical), by subspecialty, by style (description of a clinical finding or sign, clinical management of a case, application of a concept, calculation/classification of findings, correlations between diseases, or anatomy), and by target academic year (all, second/third year, or third year only).
Background: The aim of this study was to analyze the nutritional quality of mid-afternoon snacks for schooled children aged 3 to 12 years in three areas of Catalonia (Spain).
Methods: A descriptive observational study collected information on habits and the mid-afternoon snack of 782 schooled children aged 3 to 12 years in three cities, Barcelona, Girona, and Lleida, located in Catalonia (Spain). The children's families voluntarily agreed to complete an online questionnaire that collected information about demographic data and snacking habits in the afternoon, as well as a record of mid-afternoon snack intake over three school days.
