Environmental pollution, trade openness and the health of middle-aged and elderly people: an analysis of threshold effect based on data from 111 prefecture-level cities in China.

Background: Environmental pollution seriously endangers people's physical and mental health, especially the health of middle-aged and elderly people. Environmental pollution, trade openness, and population health are interconnected. Environmental pollution may have a nonlinear impact on health, and the impact of trade openness on the health effects of environmental pollution may not be a simple strengthening or weakening effect.

Promoting Charge-Carriers Dynamics by Relaxed Lattice Strain in A-site-Doped Halide Perovskite for Photocatalytic H Evolution.

Because of the unique and superior optoelectronic properties, metal halide perovskites (MHPs) have attracted great interest in photocatalysis. Element doping strategy is adopted to modify perovskite materials to improve their photocatalytic performance. However, the contribution of bare doping-site onto photocatalytic efficiency, and the correlation between doping locations and activity have not yet to be demonstrated.

Burden of non-communicable diseases attributable to high temperature in a changing climate from 1990 to 2019: a global analysis.

Background: With global climate change, the health threats of ambient high temperature have received widespread attention. However, latest spatio-temporal patterns of the non-communicable diseases (NCDs) burden attributable to high temperature have not been systematically reported. We aimed to analyze vulnerable areas and populations based on a detailed profile for the NCDs burden attributable to high temperature globally.

Disease burden of COPD attributable to PM in China, Japan and South Korea from 1990 to 2019: a comparative study based on Global Burden of Disease Study 2019.

Objective: We hope to reveal the changing trends of chronic obstructive pulmonary disease (COPD) burden attributable to particulate matter pollution (PM) and its age, period and cohort effects in China, Japan and Korea.

Design: We analysed the trend of COPD disease burden attributable to PM from 1990 to 2019 based on the latest Global Burden of Disease Database (GBD 2019) using JoinPoint model and analysed the effect of age, period and cohort on COPD burden attributable to PM in China, Japan and Korea from 1990 to 2019 using age-period-cohort model (model).

Setting: GBD data from 1990 to 2019.

Enhanced hydrogen evolution activity of CsPbBr nanocrystals achieved by dimensionality change.

Dimensionality plays a vital role at the nanoscale in tuning the electronical and photophysical properties and surface features of perovskite nanocrystals. Here, 3D and 1D all-inorganic CsPbBr nanocrystals were chosen as model materials to systemically reveal the dimensionality-dependent effect in photocatalytic H evolution. In terms of facilitating photoinduced electron-hole pair separation and charge transfer, as well as inducing proton reduction potential with the presence of fewer Br vacancies, 1D CsPbBr nanorods gave about a 5-fold improvement for solar H evolution.

Efficacy of digital breast tomosynthesis combined with magnetic resonance imaging in the diagnosis of early breast cancer.

Background: The incidence and mortality rate of breast cancer in China rank 120 and 163, worldwide, respectively. The incidence of breast cancer is on the rise; the risk increases with age but is slightly reduced after menopause. Early screening, diagnosis, and timely determination of the best treatment plan can ensure clinical efficacy and prognosis.

RADICLELESS 1 (RL1)-mediated nad4 intron 1 splicing is crucial for embryo and endosperm development in rice (Oryza sativa L.).

Pentatricopeptide repeat (PPR) proteins are one of the largest protein families in land plants. PPR proteins exhibit sequence-specific RNA-binding activity and are implicated in plant growth and development related processes. In this study, we report that the radicleless 1 (rl1) mutant in rice (Oryza sativa L.

The non-metabolizable glucose analog D-glucal inhibits aflatoxin biosynthesis and promotes kojic acid production in Aspergillus flavus.

Background: Aflatoxins (AFs) are potent carcinogenic compounds produced by several Aspergillus species, which pose serious threats to human health. As sugar is a preferred carbohydrate source for AF production, we examined the possibility of using sugar analogs to inhibit AF biosynthesis.

Results: We showed that although D-glucal cannot be utilized by A.
