Development of tetracycline-modified nanoparticles for bone-targeted delivery of anti-tubercular drug.

Since the poor response to existing anti-tuberculosis drugs and low drug concentration in local bone tissues, the traditional drug therapy does not result in satisfactory treatment of osteoarticular tuberculosis. Thus, we report a rifapentine release system with imparted bone targeting potential using tetracycline (TC) -modified nanoparticles (NPs). TC was conjugated to PLGA-PEG copolymer via a DCC/NHS technique.

Kaposi's sarcoma herpesvirus is associated with osteosarcoma in Xinjiang populations.

Osteosarcoma is the most common malignant tumor of bone predominately affecting adolescents and young adults. Based on animal studies, a viral etiology of osteosarcoma was proposed more than a half-century ago, but no viral association with human osteosarcoma has been found. The Uyghur ethnic population in Xinjiang, China, has an unusually high prevalence of Kaposi's sarcoma-associated herpesvirus (KSHV) infection and elevated incidence of osteosarcoma.

Development of Rifapentine-Loaded PLGA-Based Nanoparticles: In vitro Characterisation and in vivo Study in Mice.

Background: Tuberculosis (TB) is a leading cause of death amongst infectious diseases. The poor response to antitubercular agents necessitates the long-term use of high drug doses, resulting in low patient compliance, which is the main reason for chemotherapy failure and contributes to the development of multidrug-resistant TB. Patient non-compliance has been a major obstacle in the successful management of TB.

Development and in vitro characterization of rifapentine microsphere-loaded bone implants: a sustained drug delivery system.

Background: This study aimed to develop and evaluate a sustained drug delivery system for the treatment of osteoarticular tuberculosis (TB) to address the issues surrounding low drug concentration in lesions and bone defects or nonunion after debridement.

Methods: The effects of rifapentine on the proliferation and cell cycle of bone marrow mesenchymal stem cells (BMSCs) were evaluated by Cell Counting Kit-8 (CCK-8) and flow cytometry. Rifapentine polylactic acid (PLA) sustained-release microspheres (RPSMs) were prepared through the double emulsion solvent evaporation method and investigated the antibacterial activity in vitro.

Development of dual delivery antituberculotic system containing rifapentine microspheres and adipose stem cells seeded in hydroxyapatite/tricalcium phosphate.

Background: Low drug concentration in the tuberculosis (TB) lesion and bone defects or nonunion after debridement are two major problems that occur in the course of treating osteo-articular TB. Thus, the combination of drug-delivery system and bone tissue repair appears to be the most promising option for osteoarticular TB treatment.

Materials And Methods: Herein, we report a novel anti-TB dual delivery system based on rifapentine polylactic acid microspheres (RPMs) to treat infections, with the addition of adipose-derived mesenchymal stem cells (ASCs) seeded in hydroxyapatite/tricalcium phosphate (HA/TCP) to promote bone formation.
