Translocation of the nuclear autoantigen La to the cell surface of herpes simplex virus type 1 infected cells.
1992
Recently we developed a procedure to translocalize one of the extractable nuclear antigens (ENAs), the La protein, to the cell surface of CV-1 cells. Here we report that herpes simplex virus type 1 infection can also induce a translocation of the autoantigen to the cell surface. On the cell surface we detected La protein assembled with large protrusions. Within these protrusions La protein colocalized with virus particles. These protrusions are known to be released from the cell after virus infections. Such complexes consisting of self and virus could provide helper determinants for an anti-self response, and therefore be important in generation of autoimmunity.
Impact of VP1-Specific Protein Sequence Motifs on Adeno-Associated Virus Type 2 Intracellular Trafficking and Nuclear Entry
2012
ABSTRACT Adeno-associated virus type 2 (AAV2) has gained much interest as a gene delivery vector. A hallmark of AAV2-mediated gene transfer is an intracellular conformational change of the virus capsid, leading to the exposure of infection-relevant protein domains. These protein domains, which are located on the N-terminal portion of the structural proteins VP1 and VP2, include a catalytic phospholipase A 2 domain and three clusters of basic amino acids. We have identified additional protein sequence motifs located on the VP1/2 N terminus that also proved to be obligatory for virus infectivity. These motifs include signals that are known to be involved in protein interaction, endosomal sort…

Izturības īpašību attīstīšana futbolā pusaudžiem
2022
Futbolistu pusaudžu treniņu procesam un metodiskajiem paņēmieniem ir jābūt tik kvalitatīviem, lai tie sekmētu un attīstītu fizisko īpašību izturību. Ir daudzas metodes kā var trenēt izturības veidus. Kvalifikācijas darba tēma ir “Izturības īpašību attīstīšana futbolā pusaudžiem”. Kvalifikācijas darba mērķis ir- noskaidrot Madonas BJSS MT-6 futbola pusaudžu treniņgrupas izturības trenētību. Izstrādājot kvalifikācijas darbu, tika izmantotas sekojošas pētīšanas metodes- sporta treniņu teorijas, metodikas, sporta fizioloģijas, biomehānikas literatūras avotu pētīšana un analīze; aptaujas metode- intervija; pedagoģiskais novērojums; kvalifikācijas darba autors tika veicis kontrolvingrinājumus izt…
Impacts of Touch Screen Size, User Interface Design, and Subtask Boundaries on In-Car Task's Visual Demand and Driver Distraction
2020
Visual distraction by secondary in-car tasks is a major contributing factor in traffic incidents. In-car user interface design may mitigate these negative effects but to accomplish this, design factors’ visual distraction potential should be better understood. The effects of touch screen size, user interface design, and subtask boundaries on in-car task's visual demand and visual distraction potential were studied in two driving simulator experiments with 48 participants. Multilevel modeling was utilized to control the visual demands of driving and individual differences on in-car glance durations. The 2.5” larger touch screen slightly decreased the in-car glance durations and had a diminis…
Studentu radošuma veicināšana vizuālās mākslas studijās
2013
Anotācija Daigas Kalējas-Gasparovičas promocijas darbā ,,Studentu radošuma veicināšana vizuālās mākslas studijās”, pētot studentu radošumu un tā veicināšanu vizuālās mākslas studijās atklājot personības darbības pieeju vizuālās mākslas apguvē kā studentiem personīgi nozīmīgu radošuma attīstības iespēju, tiek izveidots teorētiski pamatots vizuālās mākslas apguves modelis un empīriski pārbaudīta tā ietekme un efektivitāte studentu radošuma veicināšanā studijās. Analizēta radošuma jēdziena daudznozīmība starpzinātņu kontekstā, teorētiskās koncepcijas mākslas pedagoģijā, atbilstoši personības darbības teorijas nostādnēm, apzinātas pedagoģiskās iespējas docētāja un studentu radošai sadarbībai.

Force transmission and interactions between synergistic muscles
2023
The classical view of muscles as independent motors has been challenged over the past decades. An alternative view has emerged in which muscles are not isolated but embedded in a three-dimensional connective tissue network that links them to adjacent muscles and other non-muscular structures in the body. Animal studies showing that the forces measured at the distal and proximal ends of a muscle are not equal have provided undisputable evidence that these connective tissue linkages are strong enough to serve as an extra pathway for muscular force transmission. In this historical review, we first introduce the terminology and anatomy related to these pathways of muscle force transmission and …
Developing Future Physical Education Teachers' Intercultural Competence: The Potential of Intertwinement of Transformative, Embodied, and Critical Ap…
2021
Purpose: This article is based on a study that explored learning processes related to intercultural competence of PE teacher trainees. The context of the study was the Faculty of Sport and Health Sciences at the University of Jyväskylä, Finland. The study was conducted in connection to two courses that focused on equality in physical education and sport in 2020–2021.Methods: Adopting an interpretive, as well as a critical approach, the authors focused on how the students described their conceptions and learning experiences. Based on their analysis they have then aimed to shed light on how interculturality, equality, equity, and diversity may be addressed in higher education in a more profou…
The Effects of Cold Water Immersion on the Recovery of Drop Jump Performance and Mechanics : A Pilot Study in Under-20 Soccer Players
2020
Cold water immersion (CWI) is a popular method used for enhancing recovery from exercise. However, the efficacy of this approach is inconclusive and studies investigating variables contributing to overall performance are scarce. Additionally, few studies have investigated the recovery of stretch-shortening cycle (SSC) performance after a fatiguing SSC task. The SSC occurs naturally in human locomotion and induces a recovery pattern different from isolated muscle contractions (e.g., pure eccentric exercise). Therefore, the main aim of this study was to investigate the effects of a single CWI on jumping performance and mechanics after exhaustive SSC exercise. On a sledge apparatus, 10 male un…
