Svelpeņu un šņāceņu izrunas traucējumu mazināšana pirmsskolas vecuma bērniem

2021

Diplomdarba nosaukums: Svelpeņu un šņāceņu izrunas traucējumu mazināšana pirmsskolas vecuma bērniem. Darba autore: Jeļena Baļuha Darba zinātniskā vadītāja: Doc. Dr. Paed. Ilze Šūmane Pētījuma mērķis: Teorētiski izzināt un praktiski pārbaudīt vingrinājumu kopu svelpeņu un šņāceņu izrunas traucējumu mazināšanai. Pētījuma hipotēze: Svelpeņu un šņāceņu izrunas traucējumu korekcija norīt veiksmīgi, ja tiek organizēts regulārs un mērķtiecīgs korekcijas darbs, izmantojot dažādus vingrinājumus. Teorētiskajā daļā tiek analizēta zinātniskā literatūra par pirmsskolas vecuma bērnu attīstības īpatnībām, raksturotas pirmsskolas vecuma bērnu runas attīstības un apguves likumsakarības, apkopota informācija…

Synthesis and Structure-Affinity Relationships of Spirocyclic Benzopyrans with Exocyclic Amino Moiety

2019

σ1 and/or σ2 receptors play a crucial role in pathological conditions such as pain, neurodegenerative disorders, and cancer. A set of spirocyclic cyclohexanes with diverse O-heterocycles and amino moieties (general structure III) was prepared and pharmacologically evaluated. In structure-activity relationships studies, the σ1 receptor affinity and σ1:σ2 selectivity were correlated with the stereochemistry, the kind and substitution pattern of the O-heterocycle, and the substituents at the exocyclic amino moiety. cis-configured 2-benzopyran cis-11b bearing a methoxy group and a tertiary cyclohexylmethylamino moiety showed the highest σ1 affinity ( Ki = 1.9 nM) of this series of compounds. In…
