In this study, we examined the relationship between fatigue and plasma concentrations of antioxidants and lipid peroxidation products. Fourteen healthy volunteers performed overnight desk work for 18h then took a nap for 4h. Participants answered questionnaires of subjective symptoms of fatigue (QSSF) and completed a self-assessment of fatigue using a visual analog scale (VAS). At each test time, they underwent a critical flicker frequency (CFF) test and blood samples were collected. Plasma levels of α-tocopherol (αT) decreased and α-tocopherylquinone (αTQ), the oxidation product of αT, increased. The ratio of 7β-hydroxycholesterol (7β-OHCh), the oxidation product of cholesterol, against total cholesterol increased until the end of experiment. αTQ levels correlated with VAS and QSSF scores. The ratio of 7β-OHCh to total cholesterol and the value of CFF showed a significant correlation. From these results, plasma levels of αTQ and 7β-OHCh are useful and objective indicators of fatigue induced by overnight deskwork.

Self -reported bruxism in patients undergoing Orthodontic treatment - a cross-sectional study.
BMC Oral Health

Department of Surgery, Program Director Orthodontics Residency Program, Section of Dentistry, The Aga Khan University Hospital, Stadium Road, P.O Box 3500, Karachi, 74800, Pakistan.
Background: Orthodontic treatment involves manipulation of tooth position that can temporarily lead to occlusal interferences capable of inducing bruxism. The objectives of this study were to determine the self-reported incidence of bruxism and its association with factors such as facial type, divergence, skeletal and dental malocclusions in orthodontic patients.
Materials And Methods: 80 patients who underwent a minimum of six months of orthodontic treatment were surveyed using a validated self-reported bruxism questionnaire for the presence or absence of bruxism.

Introduction And Importance: Insulinomas are rare pancreatic neuroendocrine neoplasms with an incidence of one to four cases per million annually and a 5 % to 10 % association with hereditary multiple endocrine neoplasia type-1. While most insulinomas are benign and well-encapsulated, approximately 6 % may have malignant potential. Intraoperative localization remains a vital component of treatment, often facilitated by modern imaging techniques like intraoperative ultrasound and fluorescence modalities.

Terminal Schwann cells (TSCs) are capable of regulating acetylcholine (ACh) release at the neuromuscular junction (NMJ). We have identified GABA as a gliotransmitter at mouse NMJs. When ACh activates α7 nicotinic ACh receptor (nAChRs) on TSCs, GABA is released and activates GABA receptors on the nerve terminal that subsequently reduce ACh release.

Objective: The detrimental effects of mental fatigue (MF) have been established in sports, such as soccer, volleyball, and basketball. Mindfulness interventions are considered a promising method to help players counteract MF, but whether it could improve basketball tactical performance after MF in competition is not clear. This study aims to investigate the effect of brief mindfulness intervention on basketball tactical performance under MF.

Purpose: To investigate the effects of dynamic-static combined relaxation therapy on fatigue and sleep disorders in breast cancer patients undergoing chemotherapy.
Methods: A total of 114 patients receiving chemotherapy at Tangshan People's Hospital (September 2023-June 2024) were randomly divided into three groups: control (routine nursing), experiment group 1 (static Benson relaxation), and experiment group 2 (dynamic yoga + static Benson relaxation). The intervention lasted 8 weeks.
