DNA phosphorothioation enhances Bacillus subtilis probiotic efficacy against alcoholic gut-liver injury

This study demonstrates that DNA phosphorothioation enhances *Bacillus subtilis* stress tolerance and probiotic efficacy against alcohol-induced gut-liver injury by neutralizing reactive oxygen species and converting taurochenodeoxycholic acid into tauroursodeoxycholic acid to activate host TGR5 signaling, thereby preserving intestinal barrier integrity and suppressing hepatic inflammation.

Integrative taxonomy of Empoascini (Hemiptera: Cicadellidae): COI barcoding for species delimitation in Argentinian agroecosystems with descriptions of a new species of Hebata and the female of Matsumurasca aculeata ​

This study employs an integrative taxonomic approach combining COI DNA barcoding and morphological analysis of genitalia to delimit Empoascini species in Argentine agroecosystems, resulting in the description of a new *Hebata* species, the first description of the female *Matsumurasca aculeata*, and the redescription of the female *M. curveola*.

Hyaluronic acid functionalized β-lactoglobulin nanocarriers enhanced tumor targeting and pH-responsive drug release through CD44-mediated endocytosis: in vitro and in vivo assessment

This study demonstrates that hyaluronic acid-functionalized β-lactoglobulin nanocarriers effectively enhance tumor targeting and pH-responsive doxorubicin delivery via CD44-mediated endocytosis, resulting in superior cytotoxicity and tumor growth inhibition with excellent biocompatibility in both in vitro and in vivo models.

The effect of smoking on microbiome composition of the anterior nares

Using data from the German National Cohort, this study demonstrates that smoking is associated with increased microbial diversity and a higher abundance of anaerobic pathobionts in the anterior nares, providing a potential mechanistic explanation for the heightened susceptibility to respiratory infections observed in smokers.

Structural characterisation of stress-responsive miRNA precursors of rice (Oryza sativa L.).

This study characterizes the secondary structural diversity and stability of approximately 150 stress-responsive pre-miRNAs in rice, identifying four distinct structural patterns and significant variations in free energy that may influence their biogenesis and function, thereby providing a foundation for designing miRNA-based strategies to enhance stress tolerance.

Transcriptomic characterization of CSF1R-high advanced gastric cancer identifies a poor- prognosis macrophage-rich subtype

This study identifies high CSF1R expression as a prognostic biomarker for poor outcomes in advanced gastric cancer, characterizing this subgroup as having a macrophage-rich tumor microenvironment with enriched inflammatory and T-cell exhaustion pathways.

Genome-wide meta-analysis of ADHD symptoms in the adult general population reveals distinct genetics of inattention and hyperactivity-impulsivity

This genome-wide meta-analysis of 141,505 adults identifies eight genetic loci associated with ADHD symptoms and reveals that inattention and hyperactivity-impulsivity have distinct genetic architectures, with the latter showing stronger links to clinical ADHD diagnoses and educational traits, while the former is more positively associated with educational outcomes.

Autofluorescence intensity patterns encode α/β cell identity in human islets

This study demonstrates that an interpretable machine-learning framework utilizing solely autofluorescence intensity patterns, rather than complex lifetime data or destructive labeling, can reliably distinguish between human pancreatic α- and β-cells based on fine-scale intracellular organization likely reflecting lipofuscin granule distribution.

Activin A Drives B-Cell Acute Lymphoblastic Leukemia Dissemination Through an ERK1/2–Cortactin Signaling Axis

This study identifies activin A as a microenvironment-derived driver of B-cell acute lymphoblastic leukemia (B-ALL) dissemination and relapse that functions through an ERK1/2–cortactin signaling axis to promote actin polymerization, cell migration, and bone marrow colonization.
