Background. Perivascular adipose tissue (PVAT) contains adipocytes and a stromal-vascular fraction with immune cells that modulate the adjacent vasculature. The presence of immune cells in PVAT of vascular beds is poorly understood—are they resident or recruited? We propose a novel resident microbiome is present in PVAT, given the immune-rich stromal environment. Hypothesis. We hypothesized the existence of distinct bacterial and viral communities in healthy PVAT compared to non-PVAT adipose tissues. Methods. PVAT samples from thoracic and abdominal aorta, mesenteric resistance arteries, non-PVAT tissues (subscapular brown adipose tissue, retroperitoneal white adipose tissue), and fecal samples were collected one year apart from male Dahl SS rats, split into two cohorts (2023 and 2024, n=3 each). Whole-genome shotgun sequencing (CosmosID) and 16S rRNA gene analysis assessed microbial relative abundance. Results. PVAT harbored bacterial and viral sequences, and species composition varied significantly between cohorts. Bacterial and viral fecal samples showed lower variability. Conclusions. This confirms a microbiome in PVAT that differed dramatically from the fecal microbiome, with temporal influences on bacterial and viral diversity, marking the first such report. These findings establish the potential of PVAT microbiota in vascular biology and immune modulation, paving the development of microbiome-targeted drugs to address vascular dysfunctions.

In a field experiment with papaya (Carica papaya L.), the effects of three soil cover types (bare soil, living cover of Canavalia ensiformis, and senescent cover) and three microbial biofertilisers (Bacillus subtilis, Pseudomonas putida, and Trichoderma viride) on crop growth and yield were evaluated. Vegetative and reproductive variables were monitored over 187 days, and the data were analysed using generalised linear mixed models (GLMMs) and generalised linear models (GLMs). The results indicated that soil cover was the dominant factor, explaining the largest proportion of variation in plant growth and final yield (p < 0.001), whereas biofertilisers did not exhibit significant main effects when applied independently. However, significant interactions between soil cover and biofertiliser were detected (p < 0.05), demonstrating that inoculant efficacy was strongly context-dependent. Trichoderma viride increased stem diameter by approximately 7% under living cover only, while Pseudomonas putida showed a comparative advantage under bare soil conditions, increasing final fruit weight by approximately 32%. Principal component analysis (PCA) further confirmed that treatment groupings were primarily driven by soil cover type. These findings provide field-based evidence that the efficiency of microbial biofertilisers in promoting papaya growth depends on edaphic conditions shaped by soil cover management. A hierarchical management strategy is therefore proposed, in which establishing a favourable soil habitat through plant cover is a prerequisite for maximising the benefits of microbial inoculants in tropical fruit production systems.

Hyaluronic acid (HA)–based nanocapsules containing plant-derived bioactives are promising formulations for dermatological applications. In this study, nanocapsules containing extracts of Arnica montana, Calendula officinalis and Aesculus hippocastanum were synthesized and their structural and functional properties were characterized. Scanning electron microscopy confirmed the formation of spherical nanostructures with uniform morphology, while rheological analyses demonstrated stable viscoelastic behavior suitable for topical application. Their antimicrobial potential was assessed on microorganisms isolated from multiple regions of healthy human skin and opportunistic pathogens. A diverse panel of approx.. 100 bacterial and fungal isolates was identified using MALDI-TOF MS. Antimicrobial activity of formulations was compared with commonly used disinfectants: H2O2, octenidine, isopropanol and topical ophthalmic antiseptic. Arnica-based formulations showed the strongest inhibitory effect against both Gram-positive and Gram-negative bacteria, whereas chestnut extract demonstrated selective activity against Candida spp. Calendula-based formulation exhibited limited antimicrobial activity. These findings demonstrate that plant-extract-loaded HA nanocapsules exhibit selective antimicrobial properties dependent on extract type and microbial group, supporting their potential as multifunctional components of future dermatological formulations.
