Hormone replacement therapy improves contractile function and myonuclear organization of single fibres from postmenopausal monozygotic female twin pa…

2013

Ageing is associated with a decline in muscle mass and strength leading to increased physical dependency in old age. Postmenopausal women experience a greater decline than men of similar age in parallel with the decrease in female sex steroid hormone production. We recruited six monozygous female twin pairs (55–59 years old) where only one twin pair was on hormone replacement therapy (HRT use = 7.8 ± 4.3 years) to investigate the association of HRT with the cytoplasmic volume supported by individual myonuclei (myonuclear domain (MND) size,) together with specific force at the single fibre level. HRT use was associated with a significantly smaller (∼27%; P < 0.05) mean MND size in muscle fib…

Change management and leading of its implementation at Rigas Juglas secondary school

2022

Latvijas Universitātes studentes Līvas Andersone bakalaura darba “Pārmaiņu vadības ieviešanas vadība Rīgas Juglas vidusskolā” mērķis ir - izpētīt pārmainu vadību Rīgas Juglas vidusskolā un piedāvāt tās pilnveides iespējas. Bakalaura darba pirmajā nodaļā autore teorētiski raksturoja pārmaiņu būtība un nepieciešamību izglītības nozarē, analizēja pārmaiņu vadības procesu, kā arī novērtēja vadītāja lomu pārmaiņu ieviešanas procesā. Otrajā nodaļā autore analizēja un apkopoja izglītības nozari Covid-19 kontekstā un raksturoja pētīto Rīgas Juglas vidusskolu. Empīriskais pētījums tika veikts, lai noskaidrotu vidusskolas pedagogu gatavību pēkšņām pārmaiņām un to vērtējumu par izglītības iestādes vad…

Skolēnu pieredzes apmaiņas programma noturīgas intereses par svešvalodu apguvi veicināšanai

2017

Maģistra darba “Skolēnu pieredzes apmaiņas programma noturīgas intereses par svešvalodu apguvi veicināšanai” ietvaros tiek pētīts jautājums, kā veicināt skolēnu intereses noturīgumu par svešvalodu apguves procesu. Autore raksturo intereses veidošanos mācību procesā un svešvalodu apguvē, pēta skolēnu pieredzes apmaiņas programmu kā svešvalodu apguves stratēģiju un tās saistību ar svešvalodu apguvi skolā. Veikts aptaujas pētījums par vispārizglītojošo skolu skolēnu un absolventu viedokļiem, lai skaidrotu interesi par svešvalodu apguves veidiem, skolēnu pieredzes apmaiņas programmu aktualitāti un nozīmi tālākajā izglītībā un karjeras izaugsmē. Izzināta situācija skolēnu pieredzes apmaiņas prog…

Cognitive behavioural therapy interventions for insomnia among shift workers: RCT in an occupational health setting

2019

Abstract Introduction The aim of the study was to compare the effectiveness of cognitive behavioural therapy interventions for insomnia (CBT-I) to that of a sleep hygiene intervention in a randomized controlled design among shift workers. We also studied whether the features of shift work disorder (SWD) affected the results. Methods A total of 83 shift workers with insomnia disorder were partially randomized into a group-based CBT-I, self-help CBT-I, or sleep hygiene control intervention. The outcomes were assessed before and after the interventions and at 6-month follow-up using questionnaires, a sleep diary, and actigraphy. Results Perceived severity of insomnia, sleep-related dysfunction…

Addition of Ethylene or Hydrogen to a Main-Group Metal Cluster under Mild Conditions

2015

Reaction of the tin cluster Sn8(Arinline image)4 (Arinline image=C6H2-2,6-(C6H3-2,4,6-Me3)2) with excess ethylene or dihydrogen at 25 °C/1 atmosphere yielded two new clusters that incorporated ethylene or hydrogen. The reaction with ethylene yielded Sn4(Arinline image)4(C2H2)5 that contained five ethylene moieties bridging four aryl substituted tin atoms and one tin–tin bond. Reaction with H2 produced a cyclic tin species of formula (Sn(H)Arinline image)4, which could also be synthesized by the reaction of {(Arinline image)Sn(μ-Cl)}2 with DIBAL-H. These reactions represent the first instances of direct reactions of isolable main-group clusters with ethylene or hydrogen under mild conditions…

Low‐Valent Germanylidene Anions: Efficient Single‐Site Nucleophiles for Activation of Small Molecules

2021

Abstract Rare mononuclear and helical chain low‐valent germanylidene anions supported by cyclic (alkyl)(amino)carbene and hypermetallyl ligands were synthesised by stepwise reduction from corresponding germylene precursors via stable and isolable germanium radicals. The electronic structures of the anions can be described with ylidene and ylidone resonance forms with the Ge−C π‐electrons capable of binding even weak electrophiles. The germanylidene anions reacted with CO2 to give μ‐CO2‐κC:κO complexes, a rare coordination mode for low‐valent germanium and inaccessible for the related neutral germylones. These results implicate low‐valent germanylidene anions as efficient single‐site nucleop…
