Cobalt chromium vanadium layered triple hydroxides have been identified as a promising electrocatalyst for seawater splitting. The insertion of vanadium as a third metal into cobalt chromium layered double hydroxides not only adds extra cationic active sites but also facilitates electronic transition from Co(II) to V(V) boosting the OER activity and suppressing the CER.

Background: Previous trials have demonstrated increased 5-year risks for adverse clinical events after coronary artery implantation of poly-l-lactic acid-based bioresorbable scaffolds (BRS) compared with cobalt chromium (CoCr) everolimus-eluting stents (EES).
Objectives: The aim of this study was to evaluate the 5-year clinical outcomes of the novel sirolimus-eluting NeoVas BRS compared with CoCr EES.
Methods: A total of 560 patients with single de novo native coronary artery lesions with reference vessel diameter 2.

Background: Individuals who have had total joint arthroplasty (TJA) are subject to lifelong exposure to metal-based implants. The relationship between chronic exposure to metal-based implants and systemic effects on the brain remains unclear. We aimed to determine the association between TJA and the subsequent long-term risk of dementia.

Objective: We previously documented that exposure to a spectrum of elements is associated with autism spectrum disorder (ASD). However, there is a lack of mechanistic understanding as to how elemental mixtures contribute to the ASD development.
Materials And Methods: Serum and urinary concentrations of 26 elements and six biomarkers of ASD-relevant pathophysiologic pathways including serum HIPK 2, serum p53 protein, urine malondialdehyde (MDA), urine 8-OHdG, serum melatonin, and urine carnitine, were measured in 21 ASD cases and 21 age-matched healthy controls of children aged 6-12 years.

Federal Research Centre of Biological Systems and Agrotechnologies of the Russian Academy of Sciences, 29, 9 Yanvarya Street, Orenburg, 460000, Russia.
Background And Aim: The global demand for efficient poultry production necessitates alternatives to antibiotic growth promoters. This study aimed to evaluate the effects of a novel four-component organic-mineral feed additive (OMFA), comprising lactulose, arginine, ultrafine silicon dioxide particles, and succinic acid, and a three-component variant (without lactulose) on growth performance, nutrient digestibility, elemental tissue composition, and the cecal microbiota of Arbor Acres broiler chickens.
Materials And Methods: One hundred and five one-day-old broiler chicks were randomly allocated into three groups: Control, Group I (four-component OMFA), and Group II (three-component OMFA).

Background: In a subset of total hip arthroplasty (THA) patients, investigators associate metal release with biological complications. Comparatively, metal release in the knee is less understood. In this study, we systematically reviewed total knee arthroplasty (TKA) metal release studies.
