Exploring Early Adolescents' Problem-Focused Strategies for Coping With Stressful IT Use Experiences

2022

In today’s technology-oriented world, individuals’ ability to cope with information technology (IT) has become increasingly important. This is especially relevant for early adolescents, who are expected to use IT from an early age on as part of their everyday lives. Although early adolescents’ IT use and its outcomes have been studied, their related coping strategies have received less attention. The current study focuses on early adolescents’ problem-focused strategies used to cope with stressful IT use experiences. The underlying data consist of semistructured interviews with 31 early adolescents. The results show that the strategies used by early adolescents differ in terms of their perv…

Effect of Non-Surgical Periodontal Treatment on Oxidative Stress Markers in Leukocytes and Their Interaction with the Endothelium in Obese Subjects w…

2020

Aim: The primary objective of this pilot study was to evaluate the effect of non-surgical periodontal treatment. The secondary aim was to evaluate the effect of dietary therapy on both parameters of oxidative stress in leukocytes and leukocyte-endothelial cell interactions in an obese population. Methods: This was a pilot study with a before-and-after design. Forty-nine obese subjects with periodontitis were randomized by means of the minimization method and assigned to one of two groups, one of which underwent dietary therapy while the other did not. All the subjects underwent non-surgical periodontal treatment. We determined periodontal, inflammatory and oxidative stress parameters&mdash

Effects of Job Content and Physical Activity on Body Mass Index among Obese Managers of the Mexican Manufacturing Industry

2020

Mental health disorders resulting from work stressors are increasing in the Mexican manufacturing industry and worldwide. Managerial positions in these contexts are highly stressful, and although physical activity may reduce the negative effects of work stress, the relationships between these two aspects regarding their effects on the body mass index (BMI) of obese managers are scarcely studied. This article aims to study such relationships by using the Job Content Questionnaire (JCQ) dimensions with the Baecke’s physical activity questionnaire dimensions and analyzing their effects on the BMI. A sample of 255 managers from the Mexican industry, with a (BMI > 30) participated by answerin…

The corticotrophin-releasing factor/urocortin system regulates white fat browning in mice through paracrine mechanisms.

2015

Objectives:\ud The corticotrophin-releasing factor (CRF)/urocortin system is expressed in the adipose tissue of mammals, but its functional role in this tissue remains unknown.\ud \ud Methods:\ud Pharmacological manipulation of the activity of CRF receptors, CRF1 and CRF2, was performed in 3T3L1 white pre-adipocytes and T37i brown pre-adipocytes during in vitro differentiation. The expression of genes of the CRF/urocortin system and of markers of white and brown adipocytes was evaluated along with mitochondrial biogenesis and cellular oxygen consumption. Metabolic evaluation of corticosterone-deficient or supplemented Crhr1-null (Crhr1−/−) mice and their wild-type controls was performed alo…

Study of the mechanisms of oxidative stress, mitochondrial function and endoplasmic reticulum stress in obesity. Role in subclinical atherosclerosis …

2019

El aumento alarmante de la prevalencia de obesidad a nivel mundial y la enorme carga de enfermedad asociada ha generado una creciente demanda de estrategias para frenar la epidemia y / o mitigar los efectos dañinos de la obesidad sobre la salud. Para ello se requiere un compromiso firme y sinérgico por parte de todas las fuerzas sociales, no sólo para desarrollar estrategias preventivas, sino también para contribuir al conocimiento de los eventos patológicos y los mecanismos involucrados en el desarrollo de esta enfermedad. Por ello, el objetivo principal de la presente tesis doctoral es profundizar en los mecanismos subyacentes de la obesidad, especialmente en aquellos relacionados con el …

Using the Questionnaire on Experience and Assessment of Work with the Italian Population

2010

The assessment of work-related stress has been an issue that has attracted attention of Italian psychologists for a long time, but only in recent years it has been remarked in the laws protecting workers. In fact, it has just been recalled the need, in a legislative decree, to place special emphasis on psychological well-being of the worker and not just on his security. The Italian professionals (Work, Organizational or Personnel Psychologists) who worked on the assessment of psychological risks of work-related stress, used instruments to assess the organizational climate primarily, by integrating qualitative m ethodologies (such as focus group) with quantitative instruments. These instrume…

Taking the acid test: Mediterranean limpets face up to climate change

2014

Impacts of climate change involve the interactions of multiple stressors on intertidal organisms, but rarely are the impacts of these stressors examined together. Many tests are also conducted in artificial, controlled laboratory conditions, without making use of natural opportunities to test performance of organisms under different environmental stressors. Given its small tidal range, the Mediterranean Sea provides such an opportunity, with a very fine scale environmental gradient and species living very close to each other over the tidal gradient. The vertical distribution of the limpets, Patella rustica and P. caerulea overlap in Palermo, Sicily, but despite this they have different ther…

WRKY gene family drives dormancy release in onion bulbs

2022

Onion (Allium cepa L.) is an important bulb crop grown worldwide. Dormancy in bulbous plants is an important physiological state mainly regulated by a complex gene network that determines a stop of vegetative growth during unfavorable seasons. Limited knowledge on the molecular mechanisms that regulate dormancy in onion were available until now. Here, a comparison between uninfected and onion yellow dwarf virus (OYDV)-infected onion bulbs highlighted an altered dormancy in the virus-infected plants, causing several symptoms, such as leaf striping, growth reduction, early bulb sprouting and rooting, as well as a lower abscisic acid (ABA) level at the start of dormancy. Furthermore, by compar…

Opetusryhmän rakenteeseen ja opettajaan liittyvien tekijöiden yhteydet opettajan ohjauskäytäntöihin

2010

Jalkanen, K. & Karvinen, S. 2010. Opetusryhmän rakenteeseen ja opettajaan liittyvien tekijöiden yhteydet opettajan ohjauskäytäntöihin. Jyväskylän yliopisto. Opettajankoulutuslaitos. Kasvatustieteen pro gradu -tutkielma. 85 sivua. Tutkimuksen tavoitteena oli analysoida 1. luokan opetusryhmissä havainnoitujen ohjauskäytäntöjen laatua sekä selvittää opetusryhmän rakenteeseen (lasten ja aikuisten sekä avustajien lukumäärä luokassa) ja opettajaan liittyvien tekijöiden (koulutus, työkokemus ja kuormitus) mahdollisia yhteyksiä ohjauskäytäntöjen laatuun. Tutkimus on osa Alkuportaat -seurantatutkimusta (Lapset, vanhemmat ja opettajat koulutien alkupolulla), jossa lapsia seurataan esiopetusvuodesta n…
