The rapid, sensitive and reliable detection of oral cancer overexpressed 1 (ORAOV 1) is crucial for the early, non-invasive diagnosis of oral squamous cell carcinoma (OSCC). Herein, we are the first to construct an ultrasensitive electrochemical (EC) biosensor based on an entropy-driven "two-way signal output" (TWSO) cyclic circuit for salivary ORAOV 1 detection. This innovative TWSO cyclic circuit can skillfully convert by-products into desired signal-generating units, not only reducing the excessive accumulation of by-products but also improving the utilization efficiency of output chains, thereby achieving rapid reaction kinetics and high signal outputs.

This daily diary study drew on the allostatic load model to examine the predictive effect of COVID-19 stressful experiences (CSE) on somatic symptoms and anxious mood, as well as applying the biological sensitivity to context model to explore whether diurnal cortisol moderated the above associations. A total of 101 Chinese college students retrospectively reported CSE in October 2020, followed by 5-day diary reports on somatic symptoms and anxious mood in November 2020, with salivary cortisol collected on Days 2 to 4 to measure cortisol awakening response (CAR), diurnal cortisol slope (DCS), and daily cortisol output (area under the curve with respect to ground, AUC). Results of multilevel models showed that greater CSE predicted more somatic symptoms but not anxious mood, which was only observed at flatter CAR, flatter DCS, or low AUC.

salivary gland hypertrophy virus (MdSGHV) affects house flies by enlarging salivary glands, impeding ovary development in females, and mating behavior in both males and females. It is not known if this virus impacts the quantity of saliva produced by house flies. This study aimed to establish baseline saliva quantities in healthy across sexes and ages and examine how MdSGHV infection influences saliva output in 5-day-old males.

Objective: Pregnancy is often typified with a decrease in sleep quality, which for many women, progressively worsens across gestation and into the postpartum. A mechanism linking poor sleep with certain adverse pregnancy outcomes is dysregulation of the HPA axis resulting in atypically elevated cortisol production. While total cortisol output normally increases across pregnancy, the cortisol awakening response (CAR), a response to waking up, is influenced by factors such as stress and mood.

Purpose: Since the last update of GEC-ESTRO (Groupe Européen de Curiethérapie - European Society for Therapeutic Radiology and Oncology) recommendations for head and neck (HN) brachytherapy in 2017, advances in understanding and management of HN cancers have influenced brachytherapy. We conducted a scoping review to depict the evolution of HN brachytherapy research and practice, and identify emerging topics since the previously published guidelines.
Material And Methods: Systematic literature search was performed in PubMed, EBSCOhost, Europe PMC, and Google Scholar databases for articles on HN brachytherapy from 2017 onwards; the search was last done on June 29, 2023.
