Chalcogen‐Bonding Interactions in Telluroether Heterocycles [Te(CH2)m]n (n=1-4; m=3-7)

2020

The Te…Te secondary bonding interactions (SBI) in solid heterocyclic telluroethers were explored by preparing and structurally characterizing a series of [Te(CH2)m]n (n = 1‐4; m = 3‐7) species. The SBIs in 1,7‐Te2(CH2)10, 1,8‐Te2(CH2)12, 1,5,9‐Te3(CH2)9, 1,8,15‐Te3(CH2)18, 1,7,13,19‐Te4(CH2)20, 1,8,15,22‐Te4(CH2)24, and 1,9,17,25‐Te4(CH2)28 led to the tubular packing of the molecules, as has been observed previously for related thio‐ and selenoether rings. The nature of the intermolecular interactions was explored by solid‐state PBE0‐D3/pob‐TZVP calculations involving periodic boundary conditions. The packing of molecules in 1,7,13,19‐Te4(CH2)20, 1,8,15,22‐Te4(CH2)24, and 1,9,17,25‐Te4(CH2)…

Conditioned generalisation in generalised anxiety disorder : the role of concurrent perceptual and conceptual cues

2021

Previous research in extinction indicates no difference in US expectancies for aversive and non-aversive unconditioned stimuli (USs). In this study, we bridged these topics by examining how concurrent perceptual and conceptual cues influence conditioned generalisation of generalised anxiety disorder (GAD) patients by using non-aversive USs. The study included two consecutive phases: acquisition and generalisation. In the acquisition phase, we used blue and purple images as the perceptually conditioned stimuli, images of animals and household items as the conceptually conditioned stimuli, and non-aversive images as unconditioned stimuli (US). In the generalisation phase, we used images conta…

Intranasal oxytocin decreases fear generalization in males, but does not modulate discrimination threshold

2021

Background: A previously acquired fear response often spreads to perceptually or conceptually close stimuli or contexts. This process, known as fear generalization, facilitates the avoidance of danger, and dysregulations in this process play an important role in anxiety disorders. Oxytocin (OT) has been shown to modulate fear learning, yet effects on fear generalization remain unknown. Methods: We employed a randomized, placebo-controlled, double-blind, between-subject design during which healthy male participants received either intranasal OT or placebo (PLC) following fear acquisition and before fear generalization with concomitant acquisition of skin conductance responses (SCRs). Twenty-…

Synthesis of phosphine derivatives of [Fe2(CO)6(μ-sdt)] (sdt = SCH2SCH2S) and investigation of their proton reduction capabilities

2023

The reactions of [Fe2(CO)6(μ-sdt)] (1) (sdt = SCH2SCH2S) with phosphine ligands have been investigated. Treatment of 1 with dppm (bis(diphenylphosphino)methane) or dcpm (bis(dicyclohexylphosphino)methane) affords the diphosphine-bridged products [Fe2(CO)4(μ-sdt)(μ-dppm)] (2) and [Fe2(CO)4(μ-sdt)(μ-dcpm)] (3), respectively. The complex [Fe2(CO)4(μ-sdt)(κ2-dppv)] (4) with a chelating diphosphine was obtained by reacting 1 with dppv (cis-1,2-bis(diphenylphosphino)ethene). Reaction of 1 with dppe (1,2-bis(diphenylphosphino)ethane) produces [{Fe2(CO)4(μ-sdt)}2(μ-κ1-dppe)] (5) in which the diphosphine forms an intermolecular bridge between two diiron cluster fragments. Three products were obtaine…

Happamuutta ja emäksisyyttä tuottava ravinto ja 12 viikon yhdistetty kestävyys- ja voimaharjoittelu miehillä ja naisilla : vaikutukset kehonkoostumuk…

2013

Johdanto. Kestävyys- ja voimaharjoittelulla saadaan aikaan muutoksia kehonkoostumuksessa niin miehillä kuin naisillakin. Kestävyysharjoittelun aikaansaamat muutokset kohdistuvat suurimmaksi osaksi rasvakudokseen ja voimaharjoittelun vastaavasti lihaskudokseen. Yhdistetyllä harjoittelulla on saatu aikaan muutoksia sekä rasva- että lihaskudoksen osuuksissa kehonkoostumuksessa. Luuntiheyteen vaikuttavat monet tekijät, kuten liikunta, ravinto, ikä ja sukupuoli. Luuntiheyden ja elimistön pH:n välillä on havaittu yhteys; happamampi elimistön pH laskee luuntiheyttä ja vastaavasti emäksisemmällä pH:lla on havaittu olevan positiivisia vaikutuksia luuntiheyteen. Edelleen on havaittu, että ruokavaliom…

The Role of Music in Everyday Life During the First Wave of the Coronavirus Pandemic : A Mixed-Methods Exploratory Study

2021

Although music is known to be a part of everyday life and a resource for mood and emotion management, everyday life has changed significantly for many due to the global coronavirus pandemic, making the role of music in everyday life less certain. An online survey in which participants responded to Likert scale questions as well as providing free text responses was used to explore how participants were engaging with music during the first wave of the pandemic, whether and how they were using music for mood regulation, and how their engagement with music related to their experiences of worry and anxiety resulting from the pandemic. Results indicated that, for the majority of participants, whi…

Vihollinen keskuudessamme : maiden saksalaisista käyty lehdistökeskustelu Britanniassa, Suomessa ja Venäjällä ensimmäisen maailmansodan alusta loppuk…

2018

Saksasta tuli vihollisvalta Britannialle, Venäjälle ja Suomelle Venäjän osana ensimmäisen maailmansodan sytyttyä. Tutkielmassa analysoin Britannian, Venäjän ja Suomen lehdistön suhtautumista maansa saksalaisvähemmistöön ensimmäisen maailmansodan alkuvaiheesta heinäkuun lopulta 1914 toukokuun alkuun 1915. Tarkastelen, millaisia teemoja nousi esille ja millaista keskustelua käytiin näiden maiden lehdistössä maan saksalaiskysymyksen osalta sekä miten nämä erosivat eri maiden lehdistöjen välillä. Alkuperäisaineistona käytän Britannian osalta liberaalin The Manchester Guardianin, oikeistonationalistisen Daily Mailin ja konservatiivisen The Daily Telegraphin pääkirjoituksia. Alkuperäisaineistona …

Music-listening as an intervention for chronic pain relief : a case study

2014

The field of audioanalgesia is vast. Research shows a combination of pharmacology and music interventions helps to reduce anxiety and stress, resulting in lower levels of pain, pre- and post-operatively. This study is an exploration of the use of music-listening as a method of pain relief with the knowledge that certain types of music aid in reaching altered states of consciousness. In reaching this state of relaxation, the realisation one’s own methods of pain management and goals towards better health are easier. This paper also discusses the importance of collaboration between various ways of practicing medicine, as well as how vital it is to be aware of one’s body and external stresses …
