Endoplasmic reticulum stress in the salivary glands of patients with primary Sjögren's syndrome, associated Sjögren's syndrome, and non-Sjögren's sicca syndrome: a comparative analysis and the influence of chloroquine.

Background: Endoplasmic reticulum stress (ERS) and the unfolded protein response (UPR) are adaptive mechanisms for conditions of high protein demand, marked by an accumulation of misfolded proteins in the endoplasmic reticulum (ER). Rheumatic autoimmune diseases (RAD) are known to be associated with chronic inflammation and an ERS state. However, the activation of UPR signaling pathways is not completely understood in Sjögren's disease (SD).

Serious games vs. traditional tutorials in the pandemic: a randomised controlled trial.

Background And Aim: The COVID-19 pandemic necessitated the transition to online medical education. This study evaluated the efficacy of online case-based tutorials using a serious game tutorial [PlayMed™ (PM)], as compared to a traditional slideshow tutorial (TT).

Methods: We performed a prospective, mixed-methods, randomised controlled trial on undergraduate medical students during the COVID-19 pandemic, from May 2020 to January 2021.

Physico-Chemical Characterizations of Composited Calcium-Ortho-Phosphate Porous Particles and Their Controlled Release Behavior of Clindamycin Phosphate and Amikacin Sulfate.

The porous particles prepared from composited calcium-ortho-phosphate (biphasic), Thai silk fibroin, gelatin, and alginate, with an organic to inorganic component ratio of 15.5:84.5, were tested for their abilities to control the release of the commercialized antibiotic solutions, clindamycin phosphate (CDP) and amikacin sulfate (AMK).

Validation of Clinical Protocol of Astigmatism Induction in Pseudophakic Patients.

Purpose: Validate a novel approach for assessing residual astigmatism's impact on visual acuity in pseudophakic patients using defocus curves and spherical equivalent compensation.

Materials And Methods: Thirteen patients over 40 with cataracts and normal ophthalmological examinations were enrolled in a prospective, non-randomized cohort study. The defocus curve method was employed, wherein visual acuity was measured with spherical lenses ranging from -2.

Brain and behavioural anomalies caused by haploinsufficiency are corrected by vitamin B12.

The brain-related phenotypes observed in 22q11.2 deletion syndrome (DS) patients are highly variable, and their origin is poorly understood. Changes in brain metabolism might contribute to these phenotypes, as many of the deleted genes are involved in metabolic processes, but this is unknown.
