Exercise combined with vitamin D supplementation has additive health effects on short physical performance battery and stair climbing in older adults: a scope review of randomised controlled trials.

This scoping review aimed to evaluate the effect of exercise combined with vitamin D supplementation on skeletal muscle health in older individuals. We implemented a systematic search of electronic databases, including PubMed, the Cochrane Library, Web of Science and Embase, which was conducted from the time of library construction to January 2024. Eligible studies were randomised controlled trials including men and women aged ≥ 65 years or mean age ≥ 65 years; exercise training and vitamin D supplementation; outcomes of muscular strength, function, muscular power, body composition and quality of life; and results compared with those of exercise intervention alone.

Preparation, characterization, and catalytic performances of a pyrazine dicarboxylate-bridging rare-earth-containing polytungstoarsenate aggregate for selective oxidation of thiophenes and deep desulfurization of model fuels.

A new polytungstoarsenate, K6LiH6[Ce4(H2O)14(pzdc)(H2pzdc)As3W29O103]·22H2O (1) (H2pzdc = 2,3-pyrazinedicarboxylic acid), was synthesized via a conventional aqueous solution method. In this synthetic approach, the organic ligand pyrazine dicarboxylate acid was introduced into the arsenotungstate system. The synthesized compound 1 was well characterized using elemental analysis, IR spectroscopy, UV-vis spectroscopy, thermogravimetric analysis (TGA), powder X-ray diffraction (PXRD), and single-crystal X-ray diffraction.

Synthesis and characterization of a Sb(v)-containing polyoxomolybdate serving as a catalyst for sulfoxidation.

A Sb-containing Anderson-based polyoxomolybdate cluster, [(CH3)4N]4H8[Na5Sb3(Sb2Mo12O57)]·17H2O [1; (CH3)4N+ = TMA+], has been successfully synthesized by using an aqueous solution method and structurally characterized. In particular, UV-Vis spectroscopy has been employed to elucidate the stability of the polyoxoanions. Under mild conditions, the catalyst demonstrates high activity and selectivity for the sulfoxidation of various sulfides in the presence of hydrogen peroxide.

A Crown-Shaped Ru-Substituted Arsenotungstate for Selective Oxidation of Sulfides with Hydrogen Peroxide.

An acetate-bridged Ru-substituted arsenotungstate [H N(CH ) ] [As W O {Ru (CH COO)} ]⋅22 H O (1) has been synthesized and structurally characterized. Four Ru atoms occupy the respective lacunary S2 sites of the crown-shaped polyanion [As W O ] , and each Ru atom is coordinated by one As atom and five μ -O atoms, comprising four from the S2 site and one from the acetate ligand. To the best of our knowledge, this coordination of the Ru atom, with an Ru-As bond length of 2.

Organophosphonate-Functionalized Lanthanopolyoxomolybdate: Synthesis, Characterization, Magnetism, Luminescence, and Catalysis of HO-Based Thioether Oxidation.

A novel class of organophosphonate-based polyoxomolybdate derivatives, KH[Ln(HO){(MoO)(OPCHCOO)}]·23HO (Ln = Gd (1Gd), Tb (2Tb), Dy (3Dy)), have been fully investigated by a few characterization methods such as single-crystal X-ray crystallography, XRPD, elemental analysis, TGA, and IR spectra. The magnetic properties of 1Gd, 2Tb, and 3Dy were investigated, as well as the solid-state luminescence properties of 2Tb and 3Dy. The catalysis properties of 1Gd, 2Tb, and 3Dy for thioether oxidization have been investigated using hydrogen peroxide (HO) as an oxidant.

The Polyoxovanadate-Based Carboxylate Derivative KH[VV(OH)O(OOC(CH)COO)]·nHO: Synthesis, Crystal Structure, and Catalysis for Oxidation of Sulfides.

The high-nuclearity polyoxovanadate-based carboxylate derivative KH[VV(OH)O(OOC(CH)COO)]·nHO (1) has been successfully synthesized by conventional aqueous methods and structurally characterized. The [VV(OH)O(OOC(CH)COO)] polyanion is built up from three cages: one {V(OH)O} cage and two identical [(VO)(OOC(CH)COO)] cages. Of the three cages, the {V(OH)O} is a purely inorganic polyoxovanadate cluster, whereas each of the [(VO)(OOC(CH)COO)] cages is a vanadium-based organic-inorganic hybrid cluster framed via four adipate ligands linking simultaneously to two triangular {V} units.

Synthesis, characterization and catalytic epoxidation properties of lanthanide-stabilized peroxoisopolytungstates.

A series of new lanthanide-containing peroxoisopolyoxotungstates, KNa[H{Ln(WO)(HO)[WO(O)]}]·105HO [Ln = Ce (1), Nd (2), Sm (3), Tb (4), Er (5)], have been successfully synthesized and structurally characterized. All polyanions [Ln(WO)(HO){WO(O)}] are isostructural and consist of a central [Ln(WO)(HO)] cluster surrounded by four peripheral [WO(O)] units. They could act as efficient recyclable catalysts for the epoxidation of various alkenes including different cycloalkenes, styrene derivatives, internal and long-chain alkenes.

A Monomeric Tricobalt(II)-Substituted Dawson-Type Polyoxometalate Decorated by a Metal Carbonyl Group: [PWOCo(HO)(OH)Mn(CO)].

A monomeric tricobalt(II)-substituted phosphotungstate polyanion, [HPWOCo], is stabilized by the attachement of an organometallic group, {Mn(CO)}, for the first time. The resulting polyoxometalate-supported [Mn(CO)] complex (1) can be used as an efficient catalyst in the cycloaddition of CO with epoxides under mild reaction conditions with pyrrolidinium bromide as a cocatalyst. Besides, magnetic measurements show that the compound exhibits weaker ferromagnetic interactions at low temperature.
