Recent Prevalence of Multi-Drug Resistant (MDR) Salmonella typhimurium from Tertiary Care Hospital of Lahore, Pakistan; Integrating 16S rRNA Profiling and In Silico Analysis

This study characterizes multidrug-resistant *Salmonella* Typhimurium isolates from a tertiary care hospital in Lahore, Pakistan, demonstrating their strong biofilm-forming capabilities and linking the *adrA* gene to both biofilm formation and antimicrobial resistance through integrated phenotypic, molecular, and *in silico* analyses.

Symbiont vesicle RNA sustains coral mutualism and its loss drives succession

This study reveals that reef-building coral symbionts sustain mutualism through extracellular vesicle-mediated miRNA signaling that modulates host pathways, where heat stress disrupts this communication in sensitive species but not in thermotolerant ones, thereby driving symbiont succession and bleaching.

Interneurons in the subplate are associated with cortical maturation across the foetal human cortex

By analyzing human fetal brain transcriptomes, this study reveals that the spatial distribution of GABAergic interneurons, particularly within the subplate, is synchronized with and drives regional cortical maturation across the fetal brain.

Surface scanning with oscillating, optically trapped probes

This paper introduces a photonic force microscopy method that utilizes an oscillating, optically trapped nanoparticle to scan surfaces with minimal contact forces (100 fN), achieving nanometre-precision 3D height profiling and sub-diffraction resolution on biological structures like macrophage filopodia.

Ultraweak luminescence dynamics reveal drought-induced oxidative stress and antioxidant defense mechanisms in grapevine leaves

This study demonstrates that ultraweak luminescence (UWL) intensity in grapevine leaves serves as a sensitive indicator of drought-induced oxidative stress and metabolic disruption, showing strong positive correlations with photosynthetic efficiency and energy status while negatively correlating with reactive oxygen species accumulation.

Multisensory VR navigation: from accelerated strategy convergence to behavioral predictability

This study demonstrates that a multimodal virtual reality navigation system integrating visual, auditory, tactile, and gustatory cues accelerates strategy convergence and significantly enhances behavioral predictability in rats compared to unimodal visual-only training.

Comparative analysis of coding and intergenic region pangenomes in Klebsiella pneumoniae

This study analyzes 451 *Klebsiella pneumoniae* genomes to demonstrate that intergenic regions exhibit substantial diversity and evolutionary significance comparable to protein-coding genes, underscoring the necessity of including non-coding sequences in pangenomic studies to fully understand bacterial adaptation and evolution.

Parallel frontoparietal-centered connectivity axes across cortex and cerebellum support cognitive control

Using Human Connectome Project data, this study reveals that individual variability in frontoparietal-centered connectivity axes across both the cortex and cerebellum forms a shared low-dimensional framework for hierarchical cognitive control, where motor control statistically mediates the link to cognitive flexibility.

Association of vitamin D receptor gene polymorphisms with type 2 diabetes mellitus inKurdish postmenopausal women: a case–control study

This case–control study of Kurdish postmenopausal women reveals that FokI and TaqI vitamin D receptor gene polymorphisms, along with lower serum vitamin D, calcium, and phosphorus levels, are significantly associated with increased susceptibility to type 2 diabetes mellitus, while the ApaI polymorphism shows no such association.
