Evaluating the performance and stability of microalgal-bacterial granular sludge in municipal wastewater treatment plants.

The microalgal-bacterial granular sludge (MBGS) process shows potential for carbon-neutral wastewater treatment, yet its application in wastewater treatment plants remains underexplored. This study attempted to use a continuous-flow raceway reactor to treat real municipal wastewater using the MBGS process. The results showed that the removal efficiencies of organics peaked on the fifth day, while declining trends were observed for nitrogen and phosphorus removal.

Light intensity-regulated glycogen synthesis and pollutant removal in microalgal-bacterial granular sludge for wastewater treatment.

As light intensity plays a pivotal role in the microalgal-bacterial granular sludge (MBGS) process, understanding its impact on system performance and energy dynamics is essential. This study investigated the effects of varying light intensities (20, 100, 200, and 300 μ mol/m²/s) on the performance of MBGS in urban wastewater treatment, with a particular focus on glycogen accumulation and pollutant removal. The results demonstrated that light intensity significantly influenced microbial community structure, glycogen accumulation, and pollutant removal efficiency.

Chromatin-site-specific accessibility: A microtopography-regulated door into the stem cell fate.

Biomaterials that mimic extracellular matrix topography are crucial in tissue engineering. Previous research indicates that certain biomimetic topography can guide stem cells toward multiple specific lineages. However, the mechanisms by which topographic cues direct stem cell differentiation remain unclear.

Maternal high glucose and fat diet exposure impaired vascular constriction via miR-325-3P/SHIP2/NOX2 pathway axis in offspring vessels.

Background And Objectives: Maternal western-style diets that are high in glucose and fat have well-known cardiovascular effects on offspring, yet the combined influence of such diets during pregnancy is relatively less comprehended. This study investigates the impact of maternal high glucose and fat diet (HGF) on vascular constriction in offspring and the underlying mechanisms.

Methods And Results: Pregnant Sprague-Dawley rats were provided with either HGF or control diets.

scDCA: deciphering the dominant cell communication assembly of downstream functional events from single-cell RNA-seq data.

Cell-cell communications (CCCs) involve signaling from multiple sender cells that collectively impact downstream functional processes in receiver cells. Currently, computational methods are lacking for quantifying the contribution of pairwise combinations of cell types to specific functional processes in receiver cells (e.g.
