Pāru romantisko attiecību kvalitātes saistība ar vecāku stresu pēc pirmā bērna piedzimšanas
2022
Bakalaura darba mērķis izpētīt, vai pastāv saistība starp pāra romantīsko attiecību kvalitāti ar vecāku stresu pēc pirmā bērna piedzimšanas, un atbildēt uz jautājumiem - Vai pastāv saistība starp attiecību kvalitāti un vecāku stresu? Vai mātes un tēvi atšķirīgi novertē attiecību kvalitāti pēc pirmā bērna piedzimšanas? Vai vecāku stresa rādītāji atšķiras mātēm un tēviem? Pētījumā piedalījās 60 vecāki – 30 mātes, 30 tēvi, vecumā no 18 līdz 39 gadiem, vidējais respondentu vecums mātēm 27,3 gadi un tēviem 29,7 gadi. Visiem respondentiem bija viens bērns, līdz 3 gadu vecumam, vidējais bērnu vecums 2,6 gadi. 51,7% respondenti bija neprecējušies, 48,3 % precējušies. Pētījums ir neeksperementāls, k…
MbCo in Saccharide Solid Amorphous Systems: A Combined FTIR and SAXS Study
2011
Saccharides, and in particular trehalose, are known for their efficiency in protecting biostructures against environmental stress [1], although the preservation mechanism is still debated. Experiments and simulations [2,3] on carboxy-myoglobin (MbCO) showed that the protein dynamics is highly inhibited in dry trehalose matrices, the inhibition being dependent on the water content. In these conditions, a mutual protein-matrix structural and dynamic influence is observed.Here we report a combined FTIR and SAXS study on MbCO embedded in dry amorphous matrices of trehalose and sucrose. FTIR measurements were performed at different protein/sugar ratios, focussing on the stretching band of the bo…
Homeostatic control of polyamine levels under long-term salt stress in Arabidopsis
2011
Salt stress has been frequently studied in its first osmotic phase. Very often, data regarding the second ionic phase is missing. It has also been suggested that Putrescine or/and Spermine could be responsible for salt resistance. In order to test this hypothesis under long-term salt stress, we obtained Arabidopsis thaliana transgenic plants harboring pRD29A::oatADC or pRD29A::GUS construction. Although Putrescine was the only polyamine significantly increased after salt acclimation in pRD29A::oatADC transgenic lines, this rendered in no advantage to this kind of stress. The higher Spermine levels found in WT and transgenic lines when compared to control conditions along with no increment o…
Nitrogen Availability Drives Mycorrhizal Effects on Wheat Growth, Nitrogen Uptake and Recovery under Salt Stress
2022
The arbuscular mycorrhizal (AM) symbiosis is generally considered effective in improving salt tolerance in plants; however, the advantages it offers can vary greatly depending on the context in which it occurs; furthermore, the mechanisms underlying these responses are still unclear. A study was conducted to investigate the role of nitrogen (N) availability on the effectiveness of AM symbiosis in durum wheat (Triticum durum Desf.) plants grown under salt stress. Plants were grown in pots in the absence or in presence of salt stress (soil electrical conductivity of 1.50 and 13.00 dS m−1, respectively), with or without AM fungi inoculation (Rhizophagus irregularis and Funneliformis mosseae), …

Sólo unos pocos estudios han investigado el papel protector o perjudicial de factores psicológicos sobre los principales sistemas fisiológicos involucrados en la respuesta de estrés en personas mayores. Considerando la importancia que éstos sistemas fisiológicos en la salud, el objetivo principal de esta tesis doctoral es investigar los posibles factores psicológicos que protegen o contribuyen a un mal funcionamiento del SNA y del eje HHA. Estudio 1 En el presente estudio nos hemos centrado en analizar el posible efecto negativo del rasgo de personalidad neuroticismo y del estado de ánimo depresivo en la respuesta psicofisiológica de estrés en personas mayores sanas. Los resultados mostraro…
Stress au travail et santé : situation chez les indépendants
2011
Dans de nombreux secteurs d’activité, le stress au travail est considéré comme faisant partie des risques pour la santé auxquels peuvent être confrontés les travailleurs salariés et non-salariés ou indépendants. [br/] Le terme de "stress" peut avoir plusieurs définitions en fonction des disciplines médicales, biologiques, médico-sociales, des sciences humaines et sociales qui y font référence. Quelle que soit l’approche disciplinaire, le stress peut être considéré comme un élément d’un processus complexe, à la fois biologique, psychologique et social en réponse à une situation aversive.[br/] Le régime social des indépendants (RSI), qui assure la couverture maladie et de retraite des artisan…
Social Functioning in Schizophrenia Clinical Correlations
2018
Schizophrenia remains one of the major psychiatric disorder with huge social and economic costs for the individual and community. The role of psycho-social factors is important both on the etiopathogenesis of the illness and its evolution, lack of social functioning and associated stress have impact on everyday life of people with this diagnosis. Our study of 100 subjects with schizophrenia has showed significant correlations between clinical and social items: bigger number of admissions, longest duration of the evolution, cognitive deficits, smoking, suicidal behavior, age, marital status, smoking, level of perceived stress. The social functioning was influenced by these factors, and the t…
