A Mechanism of Reducing Methane Production During Sewage Sludge Composting by Adding Urea.

The study of the effect of the mechanism of urea addition to sewage sludge and sawdust-composting substrates on methane production is still limited. In the present study, the systematic investigation of the effect of urea addition (0.18, 0.

Using Sediment Bacterial Communities to Predict Trace Metal Pollution Risk in Coastal Environment Management: Feasibility, Reliability, and Practicability.

The distribution of trace metals (TMs) in a continuous water body often exhibits watershed attributes, but the tidal gates of the coastal rivers may alter their transformation and accumulation patterns. Therefore, a tidal gate-controlled coastal river was selected to test the distribution and accumulation risks of Al, As, Cr, Cu, Fe, Mn, Ni, Sr, and Zn in the catchment area (CA), estuarine area (EA), and offshore area (OA). Associations between TMs and bacterial communities were analyzed to assess the feasibility of using bacterial parameters as ecological indicators.

Effects of Gut Bacteria on the Fitness of Rice Leaf Folder .

The rice leaf folder is an important migratory pest in Asia. Although this pest possesses diverse bacterial communities in its gut, functions of these bacteria in modulating host fitness, including development durations, pupal weight, adult longevity, and fecundity, remain unknown. We isolated gut bacteria from field-collected larvae using a culture-dependent method and identified 15 bacterial isolates.

Modeling Fibroblast-Cardiomyocyte Interactions: Unveiling the Role of Ion Currents in Action Potential Modulation.

Fibrotic cardiomyopathy represents a significant pathological condition characterized by the interaction between cardiomyocytes and fibroblasts in the heart, and it currently lacks an effective cure. In vitro platforms, such as engineered heart tissue (EHT) developed through the co-culturing of cardiomyocytes and fibroblasts, are under investigation to elucidate and manipulate these cellular interactions. We present the first integration of mathematical electrophysiological models that encapsulate fibroblast-cardiomyocyte interactions with experimental EHT studies to identify and modulate the ion channels governing these dynamics.

Transcriptome-Based Gene Modules and Soluble Sugar Content Analyses Reveal the Defense Response of Cotton Leaves to .

is a soil-borne phytopathogenic fungus causing destructive Verticillium wilt disease that greatly threats cotton production worldwide. The mechanism of cotton resistance to Verticillium wilt is very complex and requires further research. In this study, RNA-sequencing was used to investigate the defense responses of cotton leaves using varieties resistant (Zhongzhimian 2, or Z2) or susceptible (Xinluzao 7, or X7) to .
