AI Article Synopsis
Article Abstract
Store-operated calcium entry (SOCE) is mediated by the endoplasmic reticulum (ER) Ca sensors stromal interaction molecules (STIM1 and STIM2) and the plasma membrane Orai (Orai1, Orai2, Orai3) Ca channels. Although primarily regulated by ER Ca content, there have been numerous studies over the last 15 years demonstrating that all 5 proteins are also regulated through post-translational modification (PTM). Focusing primarily on phosphorylation, glycosylation and redox modification, this review focuses on how PTMs modulate the key events in SOCE; Ca sensing, STIM translocation, Orai interaction and/or Orai1 activation.

Cognitive control develops throughout adolescence, a high-risk period for bipolar disorders (BD) onset. Despite neurobehavioral abnormalities in adults with BD, there is minimal research investigating deviations in cognitive control in adolescents with BD. Cognitive control involves numerous processes.

Recent developments in optical imaging techniques, particularly multi-photon excitation microscopy that allows studies of biological interactions at a deep cellular level, have motivated intensive research in developing multi-photon absorption fluorophores. Biological tissues are optically transparent in the near-infrared region. Therefore, fluorophores that can absorb light in the near-infrared (NIR) region by multi-photon absorption are particularly useful in bio-imaging.

Background: Co-inhibitory receptors (immune checkpoints) regulate activated immune cells. Their expression on T cells can limit host defense. We hypothesized that chronic infection in patients with visceral leishmaniasis (VL) leads to expression of co-inhibitory receptors that could be markers of treatment response and clinical outcome.

Background: Store-operated calcium entry mediated by STIM (stromal interaction molecule)-1-Orai1 (calcium release-activated calcium modulator 1) is essential in endothelial cell (EC) functions, affecting signaling, NFAT (nuclear factor for activated T cells)-induced transcription, and metabolic programs. While the small GTPase Rap1 (Ras-proximate-1) isoforms, including the predominant Rap1B, are known for their role in cadherin-mediated adhesion, EC deletion of Rap1A after birth uniquely disrupts lung endothelial barrier function. Here, we elucidate the specific mechanisms by which Rap1A modulates lung vascular integrity and inflammation.

Objective: This study investigates the efficacy and feasibility of electrical stimulation (E-Stim) on sensory fibers of the plantar region during hemodialysis sessions, aiming to improve mobility in patients with diabetes by providing a connection between E-Stim and enhanced mobility with minimal patient effort required.
Research Design And Methods: Participants aged ≥18 years with diabetes undergoing hemodialysis and able to walk at least 10 m with or without aid were recruited and divided into an intervention group receiving 1-h intradialytic E-Stim three times a week and a control group using an identical nonfunctional device for 12 weeks. Gait, physical activity, patient-reported outcomes, and the technology acceptance model were assessed to evaluate the intervention's effectiveness and acceptance.
