This study investigated time-dependent changes in intracellular Ca⁺ levels in T cells, regulatory mechanisms, and functional effects after acute exercise. Male C57BL/6 mice were assigned to control and exercise groups, with the latter sacrificed at different intervals post-exercise. Murine splenic lymphocytes were isolated, and cytosolic Ca⁺ levels were measured using Fluo-3/AM.

Larvae of the flesh fly, Sarcophaga similis exhibit photoperiodic responses to control pupal diapause. Although the external coincidence model is applicable to S. similis photoperiodism, it remains unknown how the circadian clock system integrates day-length information.

Atomic layer deposition (ALD) of high-k dielectric films on MoS channels can lead to inadvertent remote electron doping of channels owing to nonequilibrium ALD conditions, such as the low temperatures and short purge times required for pinhole-free coating, as well as the weak physical adsorption of ALD precursors on MoS. In this study, we propose the application of a simple and effective HO vapor post-treatment (HO PT) at 100 °C immediately after complete integration of bottom- and top-gate monolayer MoS field-effect transistors (FETs), to address the inadvertent channel doping effect. When HO PT was applied to bottom-gate monolayer MoS FETs with an ALD-AlO passivation layer, the mitigation of channel doping was confirmed through electrical and optical measurements.

The aim of this study was to decipher the reprogramming of protective machineries and sulfur metabolism, as responses to time-dependent effect of fluoride stress for 10 and 20days in two indica rice (Oryza sativa ) varieties. Unregulated accumulation of fluoride via chloride channels (CLC1 and CLC2) in 10-day-old (cv. Khitish) and 20-day-old (cv.
