Effect of COVID-19 on Injury Incidence and Severity in Professional Female Football Players: A Cohort Prospective Study.

Background: Earlier statements suggested a negative impact of coronavirus disease 2019 (COVID-19) infection on sports performance and injury risk. With the COVID-19 pandemic under control and the dominance of a less-severe strain of the virus, there is a need to confirm whether these adverse effects still apply to the current situation.

Hypothesis: Infected players would have a higher noncontact muscle injury incidence compared with noninfected counterparts.

C-H, N-H, and O-H Bond Activations to Prepare Phosphorescent Hydride-Iridium(III)-Phosphine Emitters with Photocatalytic Achievement in C-C Coupling Reactions.

Complex IrH(PPr) () activates two different σ-bonds of 3-phenoxy-1-phenylisoquinoline, 2-(1-benzimidazol-2-yl)-6-phenylpyridine, 2-(1-indol-2-yl)-6-phenylpyridine, 2-(2-hydroxyphenyl)-6-phenylpyridine, -(2-hydroxyphenyl)-'-phenylimidazolylidene, and 1,3-di(2-pyridyl)-4,6-dimethylbenzene to give IrH{κ--[CH-isoqui-O-CH]}(PPr) (), IrH{κ--[NBzim-py-CH]}(PPr) (), IrH{κ--[Ind-py-CH]}(PPr) (), IrH{κ--[CH-py-CHO]}(PPr) (), IrH{κ--[CH-Im-CHO]}(PPr) (), and IrH{κ--[py-CHMe-CHN]}(PPr) (), respectively. The activations are sequential, with the second generally being the slowest. Accordingly, dihydride intermediates IrH{κ--[CH-isoqui-O-CH]}(PPr) (), IrH{κ--[NBzim-py-CH]}(PPr) (), IrH{κ--[Ind-py-CH]}(PPr) (), and IrH{κ--[py-CHMe-py]}(PPr) () were characterized spectroscopically.

Unequivocal Characterization of an Osmium Complex with a Terminal Sulfide Ligand and Its Transformation into Hydrosulfide and Methylsulfide.

Deprotonation of the thioamidate group of [OsH{κ-,-[NHC(CH)S]}(≡CPh)(IPr)(PPr)]OTf [; IPr = 1,3-bis(2,6-diisopropylphenyl)imidazolylidene; OTf = CFSO] results in the release of acetonitrile and formation of the terminal sulfide complex OsH(S)(≡CPh)(IPr)(PPr) (), which has been transformed into the hydrosulfide [OsH(SH)(≡CPh)(IPr)(PPr)]OTf () and the methylsulfide [OsH(SMe)(≡CPh)(IPr)(PPr)]OTf () through protonation and methylation reactions, respectively. The structure, spectroscopic characteristics, and reactivity of these compounds are compared. Reactions of and with 2-hydroxypyridine and 2-mercaptopyridine afford [OsH{κ-,-[X-py]}(≡CPh)(IPr)(PPr)]OTf [X = O (), S()].

Effectiveness of a blended school-based mindfulness program for the prevention of co-rumination and internalizing problems in Dutch secondary school girls: a cluster randomized controlled trial.

Background: A growing body of literature indicates that adolescent girls who talk with close friends about interpersonal problems or worries in an excessive, speculative way, and with an intense focus on distress (i.e., co-rumination) are at heightened risk for developing internalizing symptoms and disorders as well as reduced friendship quality.

Osmathiazole Ring: Extrapolation of an Aromatic Purely Organic System to Organometallic Chemistry.

An osmathiazole skeleton has been generated starting from the cation of the salt [OsH(OH)(≡CPh)(IPr)(PPr)]OTf (; IPr = 1,3-bis(2,6-diisopropylphenyl)imidazolylidene; OTf = CFSO) and thioacetamide; its aromaticity degree was compared with that of thiazole, and its aromatic reactivity was confirmed through a reaction with phenylacetylene. Salt reacts with the thioamide to initially afford the synthetic intermediate [OsH{κ--[NHC(CH)S]}(≡CPh)(IPr)(PPr)]OTf (). Thioamidate and alkylidyne ligands of couple in acetonitrile at 70 °C, forming a 1:1 mixture of the salts [OsH{κ--[C(Ph)NHC(CH)S]}(CHCN)(IPr)(PPr)]OTf () and [Os{κ--[CH(Ph)NHC(CH)S]}(CHCN)(IPr)]OTf ().
