Case Report: Familial hypocalciuric hypercalcemia type 1 with a novel mutation combined with Gitelman syndrome and a review of the literature.

Introduction: Familial hypocalciuric hypercalcemia (FHH) is an autosomal dominant disorder caused by an inactivating mutation in the gene, while Gitelman syndrome (GS) is an autosomal recessive renal tubular disorder resulting from a pathogenic mutation in the gene. Both genetic disorders are relatively rare. This report presents a patient with both FHH and GS, exhibiting unique clinical and genetic complexities.

How Leaching of Heavy Metals Changes. Long-Term Environmental Safety of Incineration Fly Ash Solidified by Cement.

The cement industry has achieved the harmless and resourceful disposal of incineration fly ash, but the environmental safety of heavy metals during its service life is still unknown. Therefore, the evolution of heavy metal leaching during the wet-dry cycle of the incineration of fly ash after different solidification treatments has been studied. We provide a theoretical basis for the long-term safe use of incineration fly ash after resource utilization.

The chitosan confined pyrolysis strategy enhances the catalytic performance of a carbon material based on a novel carboxyl functionalized MOF.

A carboxyl functionalized metal-organic framework [Co(TPT)(bptc)]·3HO (Co-MOF (-COOH)) was designed with the aim of grafting protective CTS onto the surface as a precursor. Compared with direct carbonization and physical mixing carbonization, (Co-MOF--CTS)-900 prepared by confined pyrolysis shows excellent catalytic reduction performance.

New Insight Into the Mechanism of Nitrite Enhancement on Heterotrophic Nitrification and Aerobic Denitrification Bacterium in Gene Expression.

The growth and nitrogen metabolism of heterotrophic nitrification-aerobic denitrification (HN-AD) bacteria are affected by nitrite, but the mechanisms underlying this for strain Acinetobacter johnsonii EN-J1 are unclear. In this study, the addition of 10 mg/L nitrite increased the reduction rate of ammonium by 1.0 mg/L/h, and 20 mg/L nitrite increased the reduction rate of nitrate by 3.

Vacancy Engineering in the First Coordination Shell of Single-Atom Catalysts for Enhanced Hydrogen and Oxygen Evolution Reactions.

Modulating the coordination environment of active centers has been proven to be an effective strategy for tuning the activity and selectivity of single-atom catalysts (SACs). However, most current research primarily focuses on altering non-metallic elements coordinating with the single metal atom. In this study, a novel approach is presented by introducing various vacancies into the first coordination shell of single-atom doped boron-carbon-nitride (BCN) catalysts, systematically evaluating their hydrogen evolution (HER) and oxygen evolution (OER) reactions performances.
