Preclinical evaluation of a novel multiplex ddPCR assay for detecting tetracycline resistance and differentiating Ureaplasma species

This study developed and validated a highly sensitive, specific, and reproducible multiplex ddPCR assay capable of simultaneously quantifying tetracycline resistance genes (tetM and int-Tn) and differentiating between Ureaplasma urealyticum and Ureaplasma parvum to guide optimal clinical treatment strategies.

Locus-resolved reconstruction of the pig UGT family reveals an isoform-collapse artifact in frozen ESM-2 retrieval

This study reconstructs the pig UGT gene family to reveal that while frozen ESM-2 embeddings improve the ranking of specific protein isoforms, they do not outperform traditional sequence-search methods in recovering additional genes once evaluation is standardized to the locus level, thereby exposing an isoform-resolution artifact in previous benchmarking.

Balancing Protein Expression and Minicell Yield in E. coliNissle 1917 via RBS Engineering

This study demonstrates that engineering ribosome-binding site (RBS) strength in *E. coli* Nissle 1917 minicells allows for the precise balancing of recombinant protein expression levels and minicell yield, revealing that while higher expression reduces production due to metabolic burden, minicells provide a superior environment for maintaining protein solubility.

In-depth characterization of the DNA methylation aging landscape links epigenetic noise and genotype-specific epigenetic aging to inflammaging

This study utilizes deep learning to classify over 800,000 CpGs into ten distinct DNA methylation aging patterns, revealing that genotype-specific methylation mediates inflammatory diseases while age-dependent epigenetic noise, driven by both immune-cell variations and cell-type-independent factors, is linked to inflammaging and mortality.

Luteolin antagonises human 5-HT3A receptor function through a non-competitive and voltage-independent mechanism

This study demonstrates that the naturally occurring flavonoid luteolin potently and reversibly inhibits human 5-HT3A receptor function through a non-competitive, voltage-independent mechanism involving specific residues I66 and W178, suggesting its potential as a scaffold for developing new receptor antagonists.

A Comparative Proteomic Analysis of Fertile and Sterile Hydatid Cysts of Echinococcus granulosus

This study employs TMT-based quantitative proteomics to identify 119 differentially expressed proteins between fertile and sterile *Echinococcus granulosus* cysts, revealing that enhanced protein synthesis and GPI-anchor biosynthesis pathways in fertile cysts likely drive their development and immune evasion, thereby offering potential targets for new anti-hydatid therapies.
