Longitudinal analysis of academic stress and its effects on salivary cortisol, alpha-amylase, and academic outcomes: Study protocol.

Introduction: Academic stress is a prevalent problem among university students, affecting both their psychological well-being and academic performance. This study aims to investigate the mediating roles of biological and psycho-behavioural variables in the relationship between academic stress and academic performance over the course of a semester. Through a longitudinal approach and using accessible data collection technologies, the results will enable the design of effective interventions to mitigate the impact of academic stress.

Formate from THF-C1 metabolism induces the AOX1 promoter in formate dehydrogenase-deficient Komagataella phaffii.

In Komagataella phaffii (Pichia pastoris), formate is a recognized alternative inducer to methanol for expression systems based on the AOX1 promoter (pAOX1). By disrupting the formate dehydrogenase encoding FDH1 gene, we converted such a system into a self-induced one, as adding any inducer in the culture medium is no longer requested for pAOX1 induction. In cells, formate is generated from serine through the THF-C1 metabolism, and it cannot be converted into carbon dioxide in a FdhKO strain.

Stigma toward people with mental disorders in mental healthcare in Chile.

Objective: This research aimed to determine the stigma toward people with mental illness among mental health personnel and identify individual, professional, and contextual predictors.

Methods: A descriptive, cross-sectional, and correlational design was used. The sample consisted of 218 mental health personnel working in Outpatient Psychiatric Units belonging to hospitals and Community Mental Health Centers in Chile.

Stress, repetitive negative thinking, and mental health in Chilean university students: an ecological momentary assessment study.

Background: Mental disorders in university students are a growing attention problem in the international community due to their high prevalence and serious consequences. One possible reason is university students' difficulties in coping with stress. Repetitive negative thinking (RNT) is a transdiagnostic process that, when combined with stress, can lead to the development of various disorders.

Streptococcus equi subsp. zooepidemicus: High molecular diversity of Argentinian strains isolated from mares with endometritis.

Streptococcus equi subsp. zooepidemicus (S. zooepidemicus) is a mucosal commensal of the lower genital tract in horses and is the most isolated bacterium causing endometritis in mares.
