Greenhouse gas fluxes and their determining factors in salt marsh wetlands along the south shore of Hangzhou Bay, East China Sea.

This study employed in-situ online monitoring to assess the impact of Spartina alterniflora harvesting on greenhouse gas emissions. Their fluxes and δC values were measured in unvegetated tidal flat, low and medium vegetation coverage areas of the salt marsh wetlands along the south shore of Hangzhou Bay about a month after harvest. The objective was to clarify fluxes changes and interactions with environmental factors.

Impact of COVID-19 pandemic measures on hospitalizations and epidemiological patterns of twelve respiratory pathogens in children with acute respiratory infections in southern China.

Objectives: To investigate the impact of COVID-19 pandemic measures on hospitalizations and the alterations and persistence of the epidemiological patterns of 12 common respiratory pathogens in children during the COVID-19 pandemic and after the cessation of the "zero-COVID-19" policy in southern China.

Methods: Respiratory specimens were collected from hospitalized children with acute respiratory infections at Shenzhen Children's Hospital from January 2020 to June 2024. Twelve common respiratory pathogens were detected using multiplex PCR.

Integrated GWAS, BSA-seq, and RNA-seq analyses to identify candidate genes associated with male fertility trait in peach.

Male sterility in peach (Prunus persica L.), characterized by the absence of fertile pollen grains in the anther, is determined by a recessive allele in homozygosis of the major gene located on chromosome 6. Developing tightly linked molecular markers can help identify appropriate peach parents or male-sterile plants for early culling in segregating progenies, thereby increasing breeding efficiency.

Enhancing CO oxidation performance by controlling the interconnected pore structure in porous three-way catalyst particles.

Highly ordered porous structured particles comprising three-way catalyst (TWC) nanoparticles have attracted attention because of their remarkable catalytic performance. However, the conditions for controlling their pore arrangement to form interconnected pore structures remain unclear. In particular, the correlation between framework thickness (distance between pores) or macroporosity and the diffusion of gaseous reactants to achieve a high catalytic performance has not been extensively discussed.

Identification of correlation relationships and establishment of regression models among multiple microbial indicators in reclaimed waters.

Monitoring and controlling microbial water quality is crucial for ensuring water reuse safety. In particular, existing water reuse guidelines and regulations normally prescribed coliform bacteria as microbial indicators. However, the use of non-unified coliform groups may bring difficulties to compare and optimize the conformity efforts on microbial surveillance.
