Variants in ZFHX3 are associated with atrial fibrillation in individuals of European ancestry

2009

We conducted meta-analyses of genome-wide association studies (GWAS) for atrial fibrillation (AF) in participants from five community-based cohorts. Meta-analyses of 896 prevalent (15,768 referents) and 2,517 incident (21,337 referents) AF cases identified a novel locus for AF (ZFHX3, rs2106261, risk ratio [RR]=1.19; P=2.3×10−7), an association that was replicated in the German AF Network (odds ratio=1.44; P=1.6×10−11). Combining the discovery and replication results, rs2106261 was significantly associated with AF (RR=1.25; P=1.8×10−15).

Synthesis and characterization of Zwitterionic Zn(II) and Cu(II) coordination compounds with ring-substituted 2,2′-biimidazole derivatives

2016

Zwitterionic coordination compounds with strongly asymmetrical charge distribution were synthesized and characterized. Ring-substituted biimidazoles were used as the primary ligands for Zn and Cu compounds. Formation of Zwitterionic coordination compound was found to be strongly dependent on the pH of the reaction medium as well as on the ring and nitrogen substituents of the ligand. Reaction of the Df-R2biim (Df-R2biim = 2,2′-bi-1R-imidazole-5,5′-dicarboxaldehyde, R = Me, Et or Pr) with ZnCl2 in neutral conditions led to binuclear compounds [Zn2Cl4(Df-R2biim)2] with two bridging ligands (1a–c). Reaction with CuCl2·2H2O gave neutral mononuclear compound [CuCl2(Df-Me2biim)] (1d) with chelati…

Modificaciones del automatismo, conducción, refractariedad miocárdicas y del patrón fibrilatorio ventricular producidas por el ejercicio físico cróni…

2011

El objetivo de este trabajo es investigar el papel de las neuronas parasimpáticas postganglionares en los cambios adaptativos producidos por el entrenamiento físico sobre el automatismo, la conducción y la refractariedad miocárdicas. Se utilizaron 41 conejos de raza New Zealand White que fueron divididos en 3 grupos: un grupo de animales control (n=14), un grupo de animales falsos operados (n=13) y un grupo de animals entrenados (n=14). Estos últimos fueron sometidos a un protocolo de entrenamiento en cinta rodante de 6 semanas de duración. El estudio electrofisiológico se realizó en corazón aislado y, por tanto, no sometido a influencias nerviosas extrínsecas ni humorales. Las propiedades …

The role of adolescents' temperament in their positive and negative emotions as well as in psychophysiological reactions during achievement situations

2019

Abstract This study examined the role of adolescents' (n = 190) temperament in their emotional reactions in achievement situations. Adolescents rated their temperament (i.e., surgency/extraversion, negative affectivity, effortful control) and completed achievement tasks in Grade 6. They also reported their emotions before and during challenging and non-challenging tasks. In addition, adolescents' autonomic nervous system reactions (i.e., skin conductance levels) were recorded. The results showed that high effortful control was related to higher levels of positive emotions independent of the degree of task difficulty. Low negative affectivity and high effortful control were related to lower …

Skolotāja un skolēna sadarbība mācību motivācijas veicināšanai vācu valodas apguvei skolā

2017

Maģistra darba nosaukums: „Skolotāja un skolēna sadarbība mācību motivācijas veicināšanai vācu valodas apguvei skolā”. Pētījuma mērķis: izpētīt skolēnu motivāciju mācīties vācu valodu un kā organizēt mācības skolā, lai skolēni būtu ieinteresēti apgūt vācu valodu. Pētījuma teorētiskajā daļā, analizējot literatūru, autore apraksta motivāciju ietekmējošos faktorus, pusaudžu vecumposma īpatnības un viņu mācību motivācijas veicināšanu skolā, pedagoga psiholoģisko pieeju darbā, pastāvīgu vācu valodas līmeņa celšanu skolēniem un pedagogiem. Balstoties uz teorētiskajā daļā gūtajām atziņām, pētījuma empīriskajā daļā autore apraksta savu pētnieciski praktisko darbību prakses vietā Tallinā un darba vi…

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…

Sports teams as complex adaptive systems: manipulating player numbers shapes behaviours during football small-sided games

2016

Small-sided and conditioned games (SSCGs) in sport have been modelled as complex adaptive systems. Research has shown that the relative space per player (RSP) formulated in SSCGs can impact on emergent tactical behaviours. In this study we adopted a systems orientation to analyse how different RSP values, obtained through manipulations of player numbers, influenced four measures of interpersonal coordination observed during performance in SSCGs. For this purpose we calculated positional data (GPS 15 Hz) from ten U-15 football players performing in three SSCGs varying in player numbers (3v3, 4v4 and 5v5). Key measures of SSCG system behaviours included values of (1) players’ dispersion, (2) …
