Size effects of microplastics on competition between crop and weed via soil microbes.

Microplastics (MPs) are widespread contaminants in agroecosystems, with potential implications for soil microbial communities, plant growth, and crop-weed interactions. This study investigates how MPs of different particle sizes influence crop-weed competition by altering soil microbial communities. Through a controlled greenhouse experiment, we examined the effects of 50 μm and 500 μm polyethylene (PE) MPs on competition between Eruca sativa (crop) and Amaranthus retroflexus (weed).

Soil viral-host interactions regulate microplastic-dependent carbon storage.

Microplastic is globally regarded as an important factor impacting biogeochemical cycles, yet our understanding of such influences is limited by the uncertainties of intricate microbial processes. By multiomics analysis, coupled with soil chemodiversity characterization and microbial carbon use efficiency (CUE), we investigated how microbial responses to microplastics impacted soil carbon cycling in a long-term field experiment. We showed that biodegradable microplastics promoted soil organic carbon accrual by an average of 2.

ANRIL regulates retinoblastoma progression via targeting autophagy by miR-328-3p/TSC1/ULK signaling.

Retinoblastoma is the most common primary intraocular malignancy of childhood. The aim of our study was to investigate the role and regulatory mechanism of the long non-coding RNA ANRIL in retinoblastoma. Here, our data demonstrated that ANRIL overexpression inhibited miR-328-3p expression, but promoted expression of autophagy-related proteins (LC3B, ATG5, and BECN1).

Electroplated Copper Additives for Advanced Packaging: A Review.

Acid copper electroplating stands as a core technology in advanced packaging processes, facilitating the realization of metal interconnects, bumps, vias, and substrate wiring between transistors. The deposition quality of copper interconnect materials has a crucial impact on the final performance of chips, directly influencing their yield, reliability, and stability. In this intricate process, additives play a pivotal role in regulating the deposition quality and behavior of metal copper.

Impact of the comprehensive remediation project on hydrological conditions in the lower reaches of the Ganjiang River.

This study undertakes a systematic analysis of the hydrological changes before and after the implementation of the Comprehensive Remediation Project in the lower reaches of the Ganjiang River. It focuses on changes in downstream inflow, ratios of flow distribution, and water levels, as well as water velocity near the gates. The results indicate a significant improvement in the spatial distribution of water resources in the lower reaches of the Ganjiang River.

Changes in leaf litter decomposition of primary Korean pine forests after degradation succession into secondary broad-leaved forests.

Forest degradation succession often leads to changes in forest ecosystem functioning. Exactly how the decomposition of leaf litter is affected in a disturbed forest remains unknown. Therefore, in our study, we selected a primary Korean pine forest (PK) and a secondary broad-leaved forest (SF) affected by clear-cutting degradation, both in Northeast China.

Changes in soil ammonia oxidizers and potential nitrification after clear-cutting of boreal forests in China.

The Korean pine and broad-leaved mixed forests are the most typical and complete ecosystem among the global boreal forests, with extremely important ecological functions. However, few studies on the changes of soil ammonia oxidizers and potential nitrification after clear-cutting of forests are reported. In this study, in contrast to primary Korean pine forests, nitrate (NO) was significantly higher in secondary broad-leaved forests, while ammonium (NH) was on the contrary.

Effects of expression on the apoptosis of scleral fibroblasts: and experiments.

Lumican serves an important role in the maintenance of sclera biomechanical properties. However, whether lumican expression is altered in myopia and the mechanisms of action involved are unknown. In the present study, the expression of lumican in cultured scleral fibroblasts and in the scleral tissue of a rat model of form-deprivation myopia was assessed.
