A Eukaryote-Featured Membrane Phospholipid Enhances Bacterial Formaldehyde Tolerance and Assimilation of One-Carbon Feedstocks.

Efficient bioassimilation of one-carbon (C1) feedstocks is often hindered by the toxicity of C1 substrates and/or intermediates. We compared the toxicity of several common C1 substrates/intermediates and found that formaldehyde imposes the highest toxicity on the representative bacterium . Besides causing chromosomal DNA and protein damage effects, here, we revealed that formaldehyde greatly impairs cell membranes.

Dynamic Insights: Unraveling Public Demand Evolution in Health Emergencies Through Integrated Language Models and Spatial-Temporal Analysis.

Background And Purpose: In public health emergencies, rapid perception and analysis of public demands are essential prerequisites for effective crisis communication. Public demands serve as the most instinctive response to the current state of a public health crisis. Therefore, the government must promptly grasp and leverage public demands information to enhance the effectiveness and efficiency of health emergency management, that is planned to better deal with the outbreak and meet the medical demands of the public.

Integration of (S)-2,3-oxidosqualene enables E. coli to become Iron Man E. coli with improved overall tolerance.

Background: While representing a model bacterium and one of the most used chassis in biomanufacturing, performance of Escherichia coli is often limited by severe stresses. A super-robust E. coli chassis that could efficiently tolerant multiple severe stresses is thus highly desirable.

Noncoding RNA-mediated macrophage and cancer cell crosstalk in hepatocellular carcinoma.

The tumor microenvironment (TME) is a well-recognized system that plays an essential role in tumor initiation, development, and progression. Intense intercellular communication between tumor cells and other cells (especially macrophages) occurs in the TME and is mediated by cell-to-cell contact and/or soluble messengers. Emerging evidence indicates that noncoding RNAs (ncRNAs) are critical regulators of the relationship between cells within the TME.

Emerging Roles of SRSF3 as a Therapeutic Target for Cancer.

Ser/Arg-rich (SR) proteins are RNA-binding proteins known as constitutive and alternative splicing (AS) regulators that regulate multiple aspects of the gene expression program. Ser/Arg-rich splicing factor 3 (SRSF3) is the smallest member of the SR protein family, and its level is controlled by multiple factors and involves complex mechanisms in eukaryote cells, whereas the aberrant expression of SRSF3 is associated with many human diseases, including cancer. Here, we review state-of-the-art research on SRSF3 in terms of its function, expression, and misregulation in human cancers.

The biological function and clinical significance of SF3B1 mutations in cancer.

Spliceosome mutations have become the most interesting mutations detected in human cancer in recent years. The spliceosome, a large, dynamic multimegadalton small nuclear ribonucleoprotein composed of small nuclear RNAs associated with proteins, is responsible for removing introns from precursor mRNA (premRNA) and generating mature, spliced mRNAs. SF3B1 is the largest subunit of the spliceosome factor 3b (SF3B) complex, which is a core component of spliceosomes.

A fast simulation method for radiation maps using interpolation in a virtual environment.

In nuclear decommissioning, virtual simulation technology is a useful tool to achieve an effective work process by using virtual environments to represent the physical and logical scheme of a real decommissioning project. This technology is cost-saving and time-saving, with the capacity to develop various decommissioning scenarios and reduce the risk of retrofitting. The method utilises a radiation map in a virtual simulation as the basis for the assessment of exposure to a virtual human.

Antibacterial Properties Enhancement of Layer-by-Layer Self-Assembled Nanofiltration Membranes.

Membrane technology is now being widely used in the field of water treatment for its unique advantages. Layer-by-layer (LbL) self-assembly technique is a convenient and versatile method of modified nanofiltration (NF) membranes fabrication, which can be used to control the thickness and the surface properties of membranes by chemical deposition of polyelectrolytes. Herein, a new kind of composite NF membrane with enhanced antibacterial properties was successfully fabricated through LbL self-assembly method, having polyether sulfone (PES) ultrafiltration (UF) membrane as support layer, N-[(2-hydroxy-3-trimethylammonium)propyl] chloride chitosan (HTCC) and polyacrylic acid (PAA) as active layer, and epichlorohydrin (ECH) as crosslinking reagent.
