Identification of Key Disulfidptosis-Related Genes and Their Association with Gene Expression Subtypes in Crohn's Disease.

Background: Crohn's disease (CD) is a persistent inflammatory condition that impacts the gastrointestinal system and is characterized by a multifaceted pathogenesis involving genetic, immune, and environmental components. This study primarily investigates the relationship between gene expression and immune cell infiltration in CD, focusing on disulfidptosis-a novel form of cell death caused by abnormal disulfide accumulation-and its impact on various immune cell populations. By identifying key disulfidptosis-related genes (DRGs) and exploring their association with distinct gene expression subtypes, this research aims to enhance our understanding of CD and potentially other autoimmune diseases.

Effect of polyethylene microplastics on antibiotic resistance genes: A comparison based on different soil types and plant types.

Microplastics (MPs) and antibiotic resistance genes (ARGs) are two types of contaminants that are widely present in the soil environment. MPs can act as carriers of microbes, facilitating the colonization and spread of ARGs and thus posing potential hazards to ecosystem safety and human health. In the present study, we explored the microbial networks and ARG distribution characteristics in different soil types (heavy metal (HM)-contaminated soil and agricultural soil planted with different plants: Bidens pilosa L.

Transcriptome and miRNA sequencing analyses reveal the regulatory mechanism of α-linolenic acid biosynthesis in Paeonia rockii.

Paeonia rockii is a promising woody oil crop because its seeds are rich in polyunsaturated fatty acids especially α-linolenic acid (ALA). ALA is an essential fatty acid that the human body cannot synthesize and is the direct synthetic precursor of eicosapentaenoic and docosahexaenoic acids, which play crucial roles in the development of the blood vessels, brain and nervous system of humans. However, the mechanisms underlying the dynamic changes in ALA during seed development are unknown.

Optimizing Fe-Based Metal-Organic Frameworks through Ligand Conformation Regulation for Efficient Dye Adsorption and C H /CO Separation.

Regulating the structure of metal-organic frameworks (MOFs) by adjusting the ligands reasonably is expected to enhance the interaction of MOFs on special molecules/ions, which has significant application value for the selective adsorption of guest molecules. Herein, two tricarboxylic ligands H L-Cl and H L-NH were designed and synthesized based on the ligand H TTCA by replacing part of the benzene rings with C=C bonds and modifying the chlorine and amino groups on the 4-position of the benzene ring. Two 3D Fe-MOFs (UPC-60-Cl and UPC-60-NH ) with the new topology types were constructed.

Optimizing zirconium metal-organic frameworks through steric tuning for efficient removal of CrO.

A ligand with a flexible conformation can be obtained by modifying functional groups. We modified H4DCBA with -CH3/-CF3 groups to construct three Zr-MOFs; the torsion of the central benzene ring changes the topologies. The three Zr-MOFs showed high adsorption rates for Cr2O72-, and the CF3-functional groups enhanced the adsorption capacity of UPC-49 for Cr2O72-.

Molecular mapping and characterization of the silkworm apodal mutant.

The morphological diversity of insects is important for their survival; in essence, it results from the differential expression of genes during development of the insect body. The silkworm apodal (ap) mutant has degraded thoracic legs making crawling and eating difficult and the female is sterile, which is an ideal subject for studying the molecular mechanisms of morphogenesis. Here, we confirmed that the infertility of ap female moths is a result of the degradation of the bursa copulatrix.
