Modulation of stomatal development and movement is a promising approach for creating water-conserving plants. Here, we identified and characterized the PagHCF106 gene of poplar (Populus alba × Populus glandulosa). The PagHCF106 protein localized predominantly to the chloroplast, and the PagHCF106 gene exhibited tissue-specific expression pattern.

Oxidative stress is a major threat to plant growth and survival. To understand how plants cope with oxidative stress, we carried out a genetic screen for Arabidopsis (Arabidopsis thaliana) mutants with altered response to hydrogen peroxide (H2O2) in root growth. Herein, we report the characterization of one of the hypersensitive mutants obtained.

Covalent organic frameworks (COFs) are often employed in oxygen reduction reactions (ORR) for hydrogen peroxide production due to their tunable structures and compositions. However, COF electrocatalysts require precise structural engineering, such as heteroatoms or metal site doping, to modulate the reaction pathway during the ORR process. In this work, we designed a tetraphenyl-p-phenylenediamine based COF electrocatalyst, namely TPDA-BDA, which exhibited excellent two-electron (2e) ORR performance with high H2O2 selectivity of 89.

Within this context, cholesterol undergoes oxidation, producing the pro-inflammatory product 7-ketocholesterol (7-KC). In this study, we observe elevated levels of 7-KC in the brains of the 3xTg mouse model of AD.

Aim: Tooth sensitivity caused by exposed dentin tubules is a common clinical problem requiring correct treatment methods. Owing to the spread of the COVID-19 virus, it has become common to use different mouthwashes, including 1.5% hydrogen peroxide (HP), before dental procedures.
