Prevention of 7-Ketocholesterol-Induced Overproduction of Reactive Oxygen Species, Mitochondrial Dysfunction and Cell Death with Major Nutrients (Pol…

2020

The brain, which is a cholesterol-rich organ, can be subject to oxidative stress in a variety of pathophysiological conditions, age-related diseases and some rare pathologies. This can lead to the formation of 7-ketocholesterol (7KC), a toxic derivative of cholesterol mainly produced by auto-oxidation. So, preventing the neuronal toxicity of 7KC is an important issue to avoid brain damage. As there are numerous data in favor of the prevention of neurodegeneration by the Mediterranean diet, this study aimed to evaluate the potential of a series of polyphenols (resveratrol, RSV

Ekrānierīču lietošanas paradumu darba laikā saistība ar darba slodzi, darba stresu un stresa pārvarēšanas stratēģijām

2021

Šī maģistra darba mērķis ir noskaidrot kādas ir saistības starp ekrānierīču lietošanas paradumiem darba laikā, darba slodzi, darba stresu un stresa pārvarēšanas stratēģijām, kā arī noskaidrot kādā mērā darba slodze, darba stress un stresa pārvarēšanas stratēģijas prognozē katru no ekrānierīču aktivitātēm darba laika. Pētījuma piedalījās 100 dalībnieku, visi algotu darbu strādājoši, dažādos amatos. No tiem bija 69 sievietes un 31 vīrietis, vecumā no 20 līdz 60 gadiem, vidējais vecums 35 gadi. Pētījumā tika izmantota Stresa pārvarēšanas stratēģiju aptauja «The COPE Inventory» (Carver, Scheier & Weintraub, 1989) un Uztvertā stresa skala «Perceived stress scale», (Cohen, Kamarck & Mermelsten, 1…

Benchmark study of undrained triaxial testing of Opalinus Clay shale: Results and implications for robust testing

2021

Triaxial testing of argillaceous rocks and shales is significantly more challenging than conventional rock mechanical testing. The challenges are mainly related to the very low permeability of these geomaterials, and their sensitivity to exposure of atmosphere and brines, which induces variations of water content, suction and effective stress. There are currently no international standards to guide service laboratories for robust testing procedures for shales. A benchmark study of undrained triaxial testing was therefore initiated with three leading service laboratories in shale testing, performing 13 tests and using two different methods of establishing sample saturation prior to deformati…

Causal and Non-Causal Frequency Domain Assessment of Spontaneous Baroreflex Sensitivity after Myocardial Infarction

2020

Acute myocardial infarction (AMI) is thought to alter the baroreflex control of arterial pressure. We tested this hypothesis investigating the changes of the cardiovascular response after AMI in comparison with young and old healthy controls studied at rest and during head-up tilt, using causal and non-causal frequency domain measures of the baroreflex sensitivity. Our results indicate: (i) the importance of using a causal approach that takes into account not only feedback but also feedforward effects in the study of interactions between the heart period and the arterial pressure; (ii) the compromised capacity of baroreceptors to control SAP fluctuations in post-AMI patients, both at rest a…

Personības iezīmes un emociju regulācijas grūtības kā uztvertā stresa prognozētājas

2022

Pētījuma mērķis bija noskaidrot kāda saistība pastāv starp uztverto stresu, personības iezīmēm un emociju regulācijas grūtībām, un pārbaudīt cik lielā mērā personības iezīmes un emociju regulācijas grūtības prognozē uztvertā stresa līmeņa rādītājus, kā arī pārbaudīt cik lielā mērā personības iezīmes prognozē emociju regulācijas grūtību kopīgo rādītāju. Pētījumā piedalījās 65 respondenti, 58 sievietes un 7 vīrieši, vecumā no 19 līdz 74 gadiem (M=34,82; SD=31,00). Pētījumā tika izmantotas 3 aptaujas: Lielā piecinieka personības aptauja, Emociju regulācijas grūtību skala un Uztvertā stresa skala. Pētījumā iegūtie rezultāti norāda, ka augstāki neirotisma rādītāji ir statistiski nozīmīgi saistīt…

Emocionālās ēšanas, uztvertā stresa un ēšanas pārliecību saistības sievietēm

2021

Pētījuma mērķis bija noskaidrot, kādas saistības pastāv starp emocionālās ēšanas, ķermeņa masas indeksa (ĶMI), vecuma, uztvertā stresa un ēšanas pārliecību rādītājiem sievietēm. Kā arī noskaidrot, kuri no uztvertā stresa, ēšanas pārliecību dimensijas un ĶMI rādītājiem statistiski nozīmīgi paredz emocionālās ēšanas rādītājus un kuras no ēšanas pārliecībām statistiski nozīmīgi paredz augstāku ĶMI sieviešu izlasē.

Deconstructing and reconstructing resilience: a dynamic network approach

2019

Resilience is still often viewed as a unitary personality construct that, as a kind of anti-nosological entity, protects individuals against stress-related mental problems. However, increasing evidence indicates that the maintenance of mental health in the face of adversity results from complex and dynamic processes of adaptation to stressors that involve the activation of several separable protective factors. Such resilience factors can reside at biological, psychological and social levels and may include stable predispositions (such as genotype or personality traits) and malleable properties, skills, capacities or external circumstances (such as gene expression patterns, emotion regulatio…
