Hormonal differences in intimate partner violence perpetrators when they cope with acute stress: A pilot study
2021
Background: Only a few studies have paid attention to the ability of perpetrators of intimate partner violence (IPVAW) against women to cope with acute stress, including hormonal pa-rameters. In fact, previous studies assessed how salivary testosterone (Tsal) and cortisol (Csal) changed after coping with an acute emotional stressor (directly related to IPVAW), and they con-cluded that an imbalance between the two hormones might be characteristic of these men. Never-theless, they neglected to examine the role of other hormones, such as salivary oxytocin (OXsal), which also seemed to play an important role in behavioral regulation, and whether this response could be generalized to other types…
Factors associated with stress when caring for a child with a short stature
2021
Short stature (SS) is one of the main diagnoses in Pediatric Endocrinology. SS can have a negative impact on family dynamics, causing stress and psychopathology. Poor adaptation by the family caregiver negatively affects the pedi- atric patient. Our objective was therefore to study the adjustment of the main family caregivers of pediatric patients with SS, analyzing the factors influencing it. One hundred and ten primary family caregivers of pediatric SS patients from hospitals in Valencia, Spain, participated. Parental stress (Pediatric Inventory for Parents), anxious and depres- sive symptoms (Hospital Anxiety and Depression Scale), family functioning (Family Cohesion and Adaptation Scale…
Chronic and Acute Effects on Skin Temperature from a Sport Consisting of Repetitive Impacts from Hitting a Ball with the Hands.
2022
Valencian handball consists in hitting the ball with the hands and it may contribute to injury development on the hands. This study aimed to analyze skin temperature asymmetries and recovery after a cold stress test (CST) in professional players of Valencian handball before and after a competition. Thirteen professional athletes and a control group of ten physically active participants were measured. For both groups, infrared images were taken at the baseline condition; later they underwent a thermal stress test (pressing for 2 min with the palm of the hand on a metal plate) and then recovery images were taken. In athletes, the images were also taken after their competition. Athletes at bas…
Vicarious Social Defeat Increases Conditioned Rewarding Effects of Cocaine and Ethanol Intake in Female Mice
2023
Stress is a critical factor in the development of mood and drug use disorders. The social defeat model is not appropriate for female rodents due to their low level of aggression. Therefore, a robust female model of social stress needs to be developed and validated. The aim of the present study was to unravel the long-lasting effects of vicarious social defeat (VSD) on the conditioned rewarding effects of cocaine and ethanol intake in female mice. Although VSD seems to be a good model for inducing behavioral and physiologic endophenotypes induced by stress, there are no studies to date that characterize the effect of VSD on cocaine or alcohol use. The results confirm that VSD females showed …
Simptomatologia depressiva, estrès percebut i suport social en adolescents víctimes de ciberassetjament
2016
espanolLos estudios sugieren que el cyberbullying conlleva graves consecuencias a nivel psicosocial para las cibervictimas, y que estas no confian en que los adultos y autoridades sean capaces de ayudarles. Por ello, el objetivo principal de este trabajo fue analizar si existen diferencias en el ajuste psicologico (depresion y estres percibido) y social (percepcion de apoyo social formal e informal) entre adolescentes victimas y no victimas de acoso a traves de las Nuevas Tecnologias de la Informacion (TIC). La muestra estuvo formada por 590 adolescentes de ambos sexos y de edades comprendidas entre los 11 y los 18 anos a los que se les pasaron para los objetivos del presente estudio las es…
Oxidative stress is associated with an increased antioxidant defense in elderly subjects: a multilevel approach.
2014
© 2014 Fonseca et al. Background: Studies of associations between plasma GSH-Px activity and cardiovascular risk factors have been done in humans, and contradictory results have been reported. The aim of our study was to assess the association between the scavenger antioxidant enzyme glutathione peroxidase (GSH-Px) activity in plasma and the presence of novel and classical cardiovascular risk factors in elderly patients. Copyright: Methods: We performed a cross-sectional study with baseline data from a subsample of the PREDIMED (PREvención con DIeta MEDiterránea) study in Spain. Participants were 1,060 asymptomatic subjects at high risk for cardiovascular disease (CVD), aged 55 to 80, selec…
Repercusión emocional en el personal de enfermería pediátrica. Revisión
2019
Repercusión emocional en el personal de enfermería pediátrica. Revisión Para el personal de enfermería pediátrica, trabajar con niños/as requiere cierta connotación psicológica y emocional. Gestionándose de manera negativa, puede ser causa de sentimientos de impotencia, incertidumbre, tristeza y excesiva vinculación emocional; en caso de hacerlo de manera positiva, se observa una atención integral al paciente y su familia. La falta de herramientas de afrontamiento efectivo ante situaciones extremas en los pacientes, como la muerte, es causa de un manejo no efectivo de la salud.
Nanotechnology for Natural Medicine: Formulation of Neem Oil Loaded Phospholipid Vesicles Modified with Argan Oil as a Strategy to Protect the Skin f…
2021
Neem oil, a plant-derived product rich in bioactives, has been incorporated in liposomes and hyalurosomes modified by adding argan oil and so called argan-liposomes and argan-hyaluro-somes. Argan oil has also been added to the vesicles because of its regenerative and protective effects on skin. In the light of this, vesicles were specifically tailored to protect the skin from oxidative stress and treat lesions. Argan-liposomes were the smallest vesicles (~113 nm); the addition of sodium hyaluronate led to an increase in vesicle size (~143 nm) but it significantly improved vesicle stability during storage. In vitro studies confirmed the free radical scavenging activity of formula-tions, irre…
Heat shock response in yeast involver changes in both transcription rates and mRNA stabilities
2011
We have analyzed the heat stress response in the yeast Saccharomyces cerevisiae by determining mRNA levels and transcription rates for the whole transcriptome after a shift from 25uC to 37uC. Using an established mathematical algorithm, theoretical mRNA decay rates have also been calculated from the experimental data. We have verified the mathematical predictions for selected genes by determining their mRNA decay rates at different times during heat stress response using the regulatable tetO promoter. This study indicates that the yeast response to heat shock is not only due to changes in transcription rates, but also to changes in the mRNA stabilities. mRNA stability is affected in 62% of …
Nutriosomes: Prebiotic delivery systems combining phospholipids, a soluble dextrin and curcumin to counteract intestinal oxidative stress and inflamm…
2018
Nutriosomes, new phospholipid nanovesicles specifically designed for intestinal protection were developed by simultaneously loading a water-soluble dextrin (Nutriose® FM06) and a natural antioxidant (curcumin). Nutriosomes were easily fabricated in a one-step, organic solvent-free procedure. The stability and delivery performances of the vesicles were improved by adding hydroxypropyl methylcellulose. All the vesicles were small in size (mean diameter ∼168 nm), negatively charged (zeta potential ∼-38 mV, irrespective of their composition), and self-assembled predominantly in unilamellar vesicles stabilized by the presence of Nutriose®, which was located in both the inter-lamellar and inter-v…
