Injectable vancomycin loaded hyaluronic acid-chitosan hydrogel for the treatment of Staphylococcus aureus septic arthritis.

Staphylococcus aureus (S. aureus) is a Gram positive opportunistic pathogen and a major cause for bacterial septic arthritis. Vancomycin is the preferred antibiotic for the treatment of methicillin resistance S.

Electrospun nanofibers of collagen and chitosan for tissue engineering and drug delivery applications: A review.

Tissue engineering plays a vital role in the medical field that addresses the repair, regeneration, and replacement of damaged tissues or organs. The development of drug-eluting electrospun nanofiber composed of biological macromolecules plays a key role in providing localized drug delivery and structural support. This review examines the recent development and impact of electrospun nanofibers in the field of tissue engineering and explores their potential applications.

Chemically modified chitosan as a functional biomaterial for drug delivery system.

Chitosan is a natural polymer that can degrade in the environment and support green chemistry. It displays superior biocompatibility, easy access, and easy modification due to the reactive amino groups to transform or improve the physical and chemical properties. Chitosan can be chemically modified to enhance its properties, such as water solubility and biological activity.

Gingival Mesenchymal Stem Cells: A Periodontal Regenerative Substitute.

Background: Gingival mesenchymal stem cells (GMSCs) are distinctive homogenous subset of mesenchymal stem cells (MSCs), which has its development from neural ectomesenchyme along with contributions from the perifollicular mesenchyme and the dental follicle proper. GMSCs stand apart from other dental MSCs owing to their ease of accessibility and availability with incredible long culture sustainability without any tumorigenic capability, and stable telomerase activity. Their capacity to differentiate into various cell lineages and inherent therapeutic effect in chronic inflammatory diseases like colitis, rheumatoid arthritis, systemic lupus erythematous (SLE) and diabetes makes them immensely valuable.

Astrocyte transcriptomic changes along the spatiotemporal progression of Alzheimer's disease.

Astrocytes are crucial to brain homeostasis, yet their changes along the spatiotemporal progression of Alzheimer's disease (AD) neuropathology remain unexplored. Here we performed single-nucleus RNA sequencing of 628,943 astrocytes from five brain regions representing the stereotypical progression of AD pathology across 32 donors spanning the entire normal aging to severe AD continuum. We mapped out several unique astrocyte subclusters that exhibited varying responses to neuropathology across the AD-vulnerable neural network (spatial axis) or AD pathology stage (temporal axis).
