This study examines the relationship between psychophysiological arousal, cognitive anxiety, and personality traits in young taekwondo athletes. A total of 20 male and 10 female taekwondo athletes (mean age = 18.6 years; ± 1.8) volunteered for the study. The Five Factor Personality Inventory and the state scale of the Spielberger State-Trait Anxiety Inventory (STAI) were used to measure personality and cognitive state anxiety. Electrodermal activity (EDA) was measured twice, one day and approximately one hour prior to the competition, to determine psychophysiological arousal. Descriptive statistics, Pearson product-moment correlations, and stepwise regression were used to analyze the data. Several "Big Five" facets were related to the EDA delta scores that were measured both one day and one hour before the competition. Two stepwise regressions were conducted to examine whether personality traits could significantly predict both EDA delta scores. The final model, containing only neuroticism from the Big Five factors, can significantly explain the variations in the EDA delta scores measured one day before the competition. Agreeableness can significantly explain variations in the EDA delta scores measured one hour before the competition. No relationship was found between cognitive anxiety and the EDA delta scores measured one hour before the competition. In conclusion, personality traits, especially agreeableness and neuroticism, might be useful in understanding arousal responses to competition.

This work aimed to evaluate the antiviral potential of compounds from Asian medicinal plants against SARS-CoV-2's main protease and spike glycoprotein, identifying dual inhibitors from these plants that target both proteins through advanced virtual screening, molecular dynamics simulations, and pharmacophore analysis. An in-house library of 335 antiviral natural products was prepared from the selected medicinal plants. Following the virtual screening of this library against the main protease and spike glycoprotein, top compounds were subjected to downstream analysis for evaluating druggability potential and toxicity analysis.

Triphenylphosphine, iodide and -chloro-arylsulfonamides could generate amidyl radicals EDA (Electron Donor-Acceptor) complexes under visible light irradiation, and this strategy enables the synthesis of valuable δ-chloro-arylsulfonamide and -arylsulfonylpyrrolidine motifs in moderate yields. This blue LED-induced method utilizes more readily available reagents, providing advantages in terms of cost efficiency, broad substrate scope, and functional-group compatibility.

Quantum chemical calculations of the six valence isoelectronic complexes [FeL], [CoL], and NiL with L = η-P, η-CH using density functional theory have been carried out. The molecular structures were investigated with a variety of methods. The analysis of the electronic structure in [Fe(η-P)] shows that the bonding situation is very similar to valence isoelectronic Ni(η-CH).

Organometallic dysprosocenium-based molecular magnets are the forefront runners in offering giant magnetic anisotropy and blocking temperatures close to the boiling point of liquid nitrogen. Attaining linearity in the organometallic dysprosocenium complexes is the key to generating giant magnetic anisotropy and blocking barriers. In the present study, we have unravelled the coordination ability of the substituted fullerene (CX) (where X = CCH, B, and N) generated by fencing around the five-membered ring of fullerene towards stabilizing a new family of exohedral dysprosium organometallic complexes showcasing giant magnetic anisotropy and blockade barriers.
