Ascorbic acid is involved in melatonin-induced salinity tolerance of maize ( L.) by regulating antioxidant and photosynthetic capacities.

Melatonin (MT), an indole compound, can boost plant growth under abiotic stress conditions. This experiment aims to elucidate the synergistic effect of MT and ascorbic acid (AsA) in mitigating salinity stress by assessing the photosynthetic and antioxidant capacity of the maize inbred lines H123 and W961. The results indicated that exogenous MT and AsA significantly improved photosynthetic efficiency and biomass of maize under salinity stress.

Synchronous Photocatalytic Redox Conversion of Chromium(VI) and Arsenic(III) by Bimetallic Fe/Ti Metal-Organic Frameworks.

In this work, bimetallic organic frameworks NH-MOFs(Fe, Ti) with different Fe/Ti molar ratios were prepared by a hydrothermal method for the synchronous redox transformation of Cr(VI) and As(III). These results showed that NH-MIL-125(Ti) was less effective in the photocatalytic removal of Cr(VI), whereas NH-MIL-88B(Fe) was less effective in the photocatalytic oxidative removal of As(III). Due to the introduction of Fe, the photocatalytic reduction removal of Cr(VI) (23.

Association of falls with risk of dementia and all-cause mortality: a cohort study of Japanese older adults with a 9-year follow-up.

Objective: Many risk factors affect dementia and all-cause mortality. However, whether falls are a risk factor for dementia and all-cause mortality is unclear. The study examines the association of falls with the risk of dementia and all-cause mortality, and whether dementia mediates the association of falls with all-cause mortality.

Epigenetics in the modern era of crop improvements.

Epigenetic mechanisms are integral to plant growth, development, and adaptation to environmental stimuli. Over the past two decades, our comprehension of these complex regulatory processes has expanded remarkably, producing a substantial body of knowledge on both locus-specific mechanisms and genome-wide regulatory patterns. Studies initially grounded in the model plant Arabidopsis have been broadened to encompass a diverse array of crop species, revealing the multifaceted roles of epigenetics in physiological and agronomic traits.

Comprehensive Passivation of Surface and Bulk Defects in Perovskite for High Efficiency Carbon-Based CsPbI3 Solar Cells.

Carbon-based perovskite solar cells (C-PSCs) have the advantages of high stability and low cost, but their mean efficiency has become an obstacle to commercialization. Defects, which are widely distributed on the surface and bulk of films, are an important factor in C-PSCs for low efficiency. The conventional post-treatment method through forming a low-dimensional (LD) perovskite layer usually fails in manipulating the bulk defects.
