Pašregulācijas stilu, tagadnes laika perspektīvu un darba intensitātes savstarpēja saistība
2017
Pētījuma “Pašregulācijas stilu, tagadnes laika perspektīvu un darba intensitātes savstarpēja saistība” mērķis bija noskaidrot kādas tagadnes laika perspektīvas un pašregulācijas stili prognozē darba intensitāti, un, vai pastāv saistība starp tagadnes laika perspektīvu, pašregulācijas stiliem un darba intensitāti. Dati tika ievākti no 148 strādājošiem cilvēkiem, kuri dzīvo dažādās Latvijas pilsētās, vecumā no 25 līdz 65 gadiem (vidējais vecums M = 38,03 gadi SD = 12,46), no kuriem 76 (51,35%) bija sievietes un 72 vīrieši (48,65%). Datu ievākšanai tika izmantotas šādas metodes: Pašregulācijas stilu aptauja, Tagadnes laika perspektīvas aptauja (TLPA) un Darba intensitātes aptauja. Visas metode…
Epigenetic Regulation of Early- and Late-Response Genes in Acute Pancreatitis
2015
Abstract Chromatin remodeling seems to regulate the patterns of proinflammatory genes. Our aim was to provide new insights into the epigenetic mechanisms that control transcriptional activation of early- and late-response genes in initiation and development of severe acute pancreatitis as a model of acute inflammation. Chromatin changes were studied by chromatin immunoprecipitation analysis, nucleosome positioning, and determination of histone modifications in promoters of proinflammatory genes in vivo in the course of taurocholate-induced necrotizing pancreatitis in rats and in vitro in rat pancreatic AR42J acinar cells stimulated with taurocholate or TNF-α. Here we show that the upregulat…
Más allá de la disciplina académica: algunas consideraciones para el desarrollo en los procesos educativos
2020
Erróneamente se cree que enseñar es una actividad sencilla en la que solo basta con conocer la materia y algo de experiencia. Desconociendo los conocimientos pedagógicos y didácticos propios de la docencia y de otras áreas como la psicología cognitiva y la sociología, que facultan para ejercer de una manera profesional la enseñanza. Por otra parte, se desconoce la evolución en las prácticas y necesidades educativas del mundo contemporáneo que van más allá de un conocimiento disciplinar. En este trabajo se describen algunos factores a tener en cuenta para el desarrollo de la profesión docente, al existir una relación multidimensional (normativa, emocional, intersubjetiva), centrada en objeti…
Evaluation of accounting regulation evolution in selected countries
2018
International audience; Accounting forms a significant part of information on any enterprise and plays the most important role in different levels of enterprise' management as well as in country's. Accounting information is used by various information users, whose decisions may influence various spheres: from performance of enterprises to proceeding the state policy. Its role increased recently under conditions of modern global and competitive market economy, and will be increasing in the future. Importance of accounting information usage highlights the need of appropriate formation of such information. And accounting regulation plays the main role in the process of formation and presentati…
Power Bus Management Techniques for Space Missions in Low Earth Orbit
2021
In space vehicles, the typical configurations for the Solar Array Power Regulators in charge of managing power transfer from the solar array to the power bus are quite different from the corresponding devices in use for terrestrial applications. A thorough analysis is reported for the most popular approaches, namely Sequential Switching Shunt Regulation and parallel-input Pulse Width Modulated converters with Maximum Power Point Tracking. Their performance is compared with reference to a typical mission in low Earth orbit, highlighting the respective strengths and weaknesses. A novel solar array managing technique, the Sequential Maximum Power Tracking, is also introduced in the trade-off a…
Changes in telepsychiatry regulations during the COVID-19 pandemic: 17 countries and regions' approaches to an evolving healthcare landscape
2020

However, the degree of te…
Differential evolution of PSA-NCAM expression during aging of the rat telencephalon
2007
Changes in the ability of neuronal networks to undergo structural remodeling may be involved in the age-associated cognitive decline. The polysialylated form of the neural cell adhesion molecule (PSA-NCAM) declines dramatically during postnatal development, but persists in several regions of the young-adult rat telencephalon, where it participates, through its anti-adhesive properties, in neuronal structural plasticity. However, PSA-NCAM expression during aging has only been studied in the dentate gyrus and the piriform cortex layer II, where it is strongly downregulated in adult (middle-aged) individuals. Using immunohistochemistry, we have observed that in most of the telencephalic areas …
Defective Postnatal Neurogenesis and Disorganization of the Rostral Migratory Stream in Absence of theVax1Homeobox Gene
2004
The subventricular zone (SVZ) is one of the sources of adult neural stem cells (ANSCs) in the mouse brain. Precursor cells proliferate in the SVZ and migrate through the rostral migratory stream (RMS) to the olfactory bulb (OB), where they differentiate into granule and periglomerular cells. Few transcription factors are known to be responsible for regulating NSC proliferation, migration, and differentiation processes; even fewer have been found to be responsible for the organization of the SVZ and RMS. For this reason, we studied the ventral anterior homeobox (Vax1) gene in NSC proliferation and in SVZ organization. We found thatVax1is strongly expressed in the SVZ and in the RMS and that,…
Glutathione regulates telomerase activity in 3T3 fibroblasts.
2004
Changes in telomerase activity have been associated either with cancer, when activity is increased, or with cell cycle arrest when it is decreased. We report that glutathione, a physiological antioxidant present at high intracellular concentrations, regulates telomerase activity in cells in culture. Telomerase activity increases in 3T3 fibroblasts before exponential cell growth. The peak of telomerase activity takes place 24 h after plating and coincides with the maximum levels of glutathione in the cells. When cells are treated with buthionine sulfoximine, which decreases glutathione levels in cells, telomerase activity decreases by 60%, and cell growth is delayed. Glutathione depletion in…
