Targeting penicillin binding protein 2a in methicillin resistant Staphylococcus aureus using selected phytocompounds: an environmental surveillance and in silico molecular docking study

This study detected methicillin-resistant *Staphylococcus aureus* carrying the *mecA* gene in household harvested rainwater in Nigeria and utilized in silico molecular docking to identify epigallocatechin gallate, luteolin, andrographolide, and apigenin as promising phytocompounds for targeting the PBP2a protein, though these findings require further experimental validation.

Unravelling the mechanisms of cyanobacterial resilience in photosynthetic living materials

This study reveals that entrapping *Synechocystis* sp. PCC 6803 in calcium-alginate hydrogels induces a coordinated, maintenance-oriented physiological state characterized by proteome remodeling toward stress protection and resource reallocation, which preserves photosynthetic activity and enables long-term resilience in photosynthetic living materials.

Pan-genome analysis reveals structural variation and breeding-group divergence of the glutathione S-transferase gene family in highbush blueberry (Vaccinium corymbosum L.)

This study presents a pan-genome analysis of 23 highbush blueberry cultivars revealing that the glutathione S-transferase (GST) gene family exhibits an open pan-genome structure with significant structural variation and breeding-group divergence, ultimately identifying three Phi-class GSTs as the most credible candidates for regulating anthocyanin accumulation and fruit pigmentation.

An organ-on-chip model of vulvovaginal candidiasis to study the interplay between fungal pathogenicity and inflammation

This study presents a novel vulvovaginal candidiasis-on-chip model that successfully simulates the recruitment of neutrophils to Candida albicans-infected vaginal epithelium, enabling the investigation of the inflammatory mechanisms driving disease progression and serving as a platform for evaluating new therapies.

Genomic features of mecA-harboring Staphylococcus epidermidis infecting an illegally traded rufous-bellied thrush (T. rufiventris)

This study reports the isolation and genomic characterization of a multidrug-resistant, methicillin-resistant *Staphylococcus epidermidis* Sequence Type 280 from a skin lesion in an illegally traded rufous-bellied thrush, highlighting the role of urbanization and wildlife trade in the spread of antibiotic resistance within a One Health framework.

Spatial heterogeneity and interfacial signaling hub function of CPTCs across the ventral body wall continuum

This study reveals that Cd34+ Pdgfra+ Telocytes (CPTCs) exhibit spatial heterogeneity across the ventral body wall, with superficial fascia-resident CPTCs functioning as a dynamic interfacial signaling hub that integrates skin and muscle compartments via Wnt and Nectin pathways to coordinate cross-layer communication.

Inflammation-Associated Neuronal and Astrocytic Ensembles in the Dorsal Bed Nucleus of the Stria Terminalis Modulate Peripheral Immune Response via the Brain-Spleen Axis

This study identifies the dorsal bed nucleus of the stria terminalis (dBNST) as a critical forebrain hub where inflammation-activated neuronal ensembles and ATP-driven astrocytic signaling coordinate to modulate peripheral immune responses via a brain-spleen axis.

Circulating Brevican and Neurocan Are Reduced in Alcohol Use Disorder: A Peripheral Signature of Perineuronal Nets Alterations

This study demonstrates that patients with alcohol use disorder exhibit significantly reduced circulating levels of the perineuronal net components brevican and neurocan, which correlate with disease severity and chronicity, suggesting these proteoglycans serve as peripheral biomarkers of alcohol-induced neuroplastic disruption.

Computational metabolomics reveals flavonoid architectures underlying species-specific chemical identity in medicinal Plectranthus

This study employs computational metabolomics to demonstrate that, beyond the traditionally emphasized diterpenoids, distinct flavonoid structural patterns serve as key drivers of species-specific chemical identity in the medicinal plants *Plectranthus hadiensis* and *Plectranthus ambiguus*.
