Post-traumatic stress (PTSD) disorder is a mental health condition that can occur after experiencing or witnessing a traumatic event. The 27-F earthquake that struck Chile in 2010 was one such event that had a significant impact on the mental health of the population. A study was conducted to investigate the prevalence of PTSD and its associated fa...
Introduction
Brain-derived neurotrophic factor (BDNF) is essential for brain physiological processes influencing memory and learning. BDNF levels can be affected by many factors, including stress. Stress increase serum and salivary cortisol levels. Academic stress is of the chronic type. BDNF levels can be measure from serum, plasma or platelets, a...
Higher education represents the peak of academic stress, a complex multifactorial process with a high workload. The SISCO academic stress inventory has good psychometric properties for its subscales Stressors, Symptomatology and for the whole instrument, but not for the Coping subscale. The aim of this paper is to corroborate previous reports based...
Estrés académico, proceso multifactorial complejo que alcanza sus grados más elevados a nivel universitario y que para realizar intervenciones efectivas, necesita de instrumentos válidos y fiables para medirlo. El objetivo de este trabajo fue evaluar las propiedades psicométricas de una versión adaptada del inventario SISCO del estrés académico, de...
OBJECTIVE:
To evaluate the factorial structure and internal consistency of SISCO inventory of academic stress in medical students..
METHODS:
The cross-sectional study was conducted at the School of Medicine, University of Concepcion, Chile, in 2014, and comprised second and third year students.Exploratory factor analysis was carried out to determi...
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. T...
Background/Objectives: Post-traumatic stress disorder (PTSD) is a complex condition influenced by both genetic and environmental factors. This longitudinal study aimed to explore the connection between two specific genetic polymorphisms, Val66Met and 5-HTTLPR, and the lifetime prevalence of PTSD in patients from primary care settings. We also exami...
In a competitive and demanding world, academic stress is of increasing concern to students. This systemic, adaptive, and psychological process is composed of stressful stimuli, imbalance symptoms, and coping strategies. The SISCO-II Academic Stress Inventory (SISCO-II-AS) is a psychometric instrument validated in Chile. It evaluates stressors, symp...
Fundamento:
La atención primaria de salud trata aproximadamente el 90 % de todos los problemas de salud a nivel mundial. La utilización de los servicios de salud es alta entre las personas con trastornos mentales; de igual forma se ha establecido que los trastornos mentales representan alrededor del 6 % de todos los años de vida perdidos ajustados...
Background: Primary health care treats approximately 90% of all health problems worldwide. Health service care is high among people with mental disorders; likewise, it has been established that mental disorders represent around 6% of all disability-adjusted life years lost worldwide. Objective: To identify the lifetime and last-year prevalence of m...
Introduction
Academic stress (AS) is a prevalent challenge faced by university students, potentially affecting molecular indicators such as brain-derived neurotrophic factor (BDNF) and global DNA methylation (G-DNA-M). These indicators could illuminate the physiological ramifications of academic stress.

In this work, evidence for a critical role of Trichomonas vaginalis protein phosphatase 1 gamma (TvPP1γ) in proliferation and attachment of the parasite to the mammalian cell is provided. Firstly, proliferation and attachment of T. vaginalis parasites to HeLa cells was blocked by calyculin A (CA), a potent PP1 inhibitor. Secondly, it was demonstrat...
Las aves de consumo constituyen uno de los principales reservorios y fuente de infección humana de la campilo-bacteriosis. Se analizaron 341 muestras de deposiciones, 291 humanas y 50 aviares. De las muestras, 220 de niños con síndrome diarreico agudo-SDA (183 hospitalizados y 37 consultantes ambulatorios) y 71 niños sanos. A las 23 cepas obtenidas...
Poultry is a main reservoir and source of human infection in campylobacteriosis. Three hundred and forty one stool samples (291 human, 50 avian) were analyzed. In the human group, 220 samples were collected from children with acute diarrheal disease (183 inpatients, 37 outpatients) and 71 from healthy children. Erythromycin and ciprofloxacin agar d...
Extracellular adenosine removal is via human equilibrative nucleoside transporters 1 (hENT1) and 2 (hENT2) in the endothelium, thus regulating adenosine-induced revascularization and angiogenesis. Since human endothelial progenitor cells (hEPCs) promote revascularization, we hypothesize differential expression of nucleoside transporters in hEPCs. h...
Several bacterial species have developed physiological response to avoid the cellular damage when are exposed to carbon starvation or frozen stress. For example survival to inanition has been related to endogenous substrates consumptions. The aim of this study was to evaluate if poly-beta-hydroxylkanoates (PHA) consumption enable Sphingopyxis chile...
Campylobacter jejuni, a major causative agent of diarrhoeal syndrome in humans, is a bacterium that at low temperatures and under conditions of stress, coccoid cells form non-arable. To determine the conditions under which strains of C. jejuni is kept viable and cultivable, independent of the morphology, underwent two strains of C. jejuni three dif...
DNA ploidy and cell cycle analysis by flow cytometry is used to obtain additional information about the diagnosis and prognosis of different types of cancer. However, there are several disagreements among authors about the tissue source (fresh-frozen or paraffin embedded), cellular dissociation methods (mechanical, enzymatic or other), use of diffe...

Introducción: Los basófilos ante una segunda exposición a un alérgeno (previa sensibilización) son activados y por medio de transducción de señales vía proteína quinasa expresan en su membrana CD63. Por citometría de Flujo es posible evaluar la expresión de este marcador.
Objetivo: Evaluar la degranulación de basófilos, mediante la expresión de CD...
