Background And Purpose: Perivascular adipose tissues (PVATs) play a critical role in modulating vascular homeostasis and protecting against cardiovascular dysfunction-mediated blood pressure dysregulation. We demonstrated that the activating transcription factor-3 (Atf3) gene in the PVAT is crucial for improving vascular wall tension abnormalities; however, its protective mechanism remains unclear. Herein, we aim to determine whether ATF3 regulates PVAT-derived relaxing factor (PVDRF) biosynthesis and if its secretion contributes to vasorelaxation.

This study investigates the application of levan- produced from Paenibacillus polymyxa SG09-12 as an antiviral agent against cucumber mosaic virus (CMV). A high-purity microbial levan was produced and purified using diafiltration. The chemical composition, structure, and functional groups of the levan were characterised using high-performance liquid chromatography (HPLC), nuclear magnetic resonance (NMR), Fourier-transform infrared spectroscopy (FT-IR), and X-ray photoelectron spectroscopy (XPS).

There is an emerging quest for fabrication of water-soluble fluorescent silver nanoclusters (AgNCs) with long-lasting fluorescent properties and dimensional stability while being sustainable and functional. Thus, a well-known seed-mediated growth strategy has been developed to manufacture AgNCs supported onto carboxyl and aldehyde modified cellulose nanofiber (DATCNF) with ultra-small and intense fluorescence. The DATCNF acts as a reductant, template, and stabilizer while the protective ligand, 2-Mercaptonicotinic Acid (2-HMA), provides AgNCs with luminous characteristic and constrained size of 4.

Tissue-resident memory T (TRM) cells possess unique abilities to migrate, establish themselves in tissues, and monitor peripheral tissues without circulating. They are crucial in providing long-lasting and local immune protection against surface infections. TRMs demonstrate distinct phenotypic and functional characteristics compared to central memory T (Tcm) cells and effector memory T (Tem) cells.

Human papillomavirus (HPV) infections drive one in 20 new cancer cases, exerting a particularly high burden on women. Most anogenital HPV infections are cleared in less than two years, but the underlying mechanisms that favour persistence in around 10% of women remain largely unknown. Notwithstanding, it is precisely this information that is crucial for improving treatment, screening, and vaccination strategies.
