Abstract
AIM Thiocolchicoside (THC) is a drug under the category of BCS III. Due to its high molecular weight, it has poor oral bioavailability and low skin permeability. This study aims to find an alternative delivery method for THC that enhances its bioavailability through nasal application approach. In situ gels containing plain or liposomal THC with different combinations of Pluronic® F127 and PEG 400 were prepared. METHOD Liposome formulations were prepared using the thin film hydration method and tested for their characterization such as for drug content, particle size, and zeta potential. In vivo pharmacokinetic parameters of formulations such as Cmax, Tmax, and AUC were tested on the rabbit model. The formulations were also scrutinized for their cell viability properties. RESULT Formulation composition with 2% soybean phosphatidylcholine and 10 mg THC exhibited ∼94% entrapment efficiency, minimum particle size 101.32 nm, low polydispersity index 0.225 and +0.355 zeta potential. In situ liposomal dispersion containing 15% Pluronic® F127 turned into gel at nasal temperature. Cell lines were unharmed for 48 h. İn situ liposomal gels showed 1.5x higher blood concentration than the control formula. CONCLUSION In situ gels of liposomal THC formulations offer advantages over traditional nasal solutions, demonstrating comparable bioavailability to parenteral medication while also preserving the health of nasal mucosa cells.

Abstract
The challenges of using VEGF to promote osteoblastic differentiation include a short half-life and a narrow therapeutic window. A carrier system combining hydrogel and liposomes may improve the therapeutic efficacy of VEGF for bone regeneration. This study aimed to investigate the effects of delivery of VEGF via liposomal hydrogel on the osteogenesis of MG-63 cells. Liposomal hydrogel scaffold was fabricated and then characterized in terms of the morphological and chemical properties using FESEM and FTIR. In 2.5D analysis, the MG-63 cells were cultured on liposomal hydrogel + VEGF as the test group. The osteogenic effects of VEGF were compared with the control groups, i.e., hydrogel without liposomes + VEGF, osteogenic medium (OM) supplemented with a bolus of VEGF, and OM without VEGF. Cell morphology, viability, and differentiation and mineralization potential were investigated using FESEM, MTT assay, ALP activity, and Alizarin red staining. The characterization of scaffold showed no significant differences in the morphological and chemical properties between hydrogel with and without liposomes (p > 0.05). The final 2.5D culture demonstrated that cell proliferation, differentiation, and mineralization were significantly enhanced in the liposomal hydrogel + VEGF group compared with the control groups (p < 0.05). In conclusion, liposomal hydrogel can be used to deliver VEGF in a sustained manner in order to enhance the osteogenesis of MG-63 cells.

Glycyrrhetinic acid proliposomes mediated by mannosylated ligand: Preparation, physicochemical characterization, environmental stability and bioactivity evaluation. Colloids Surf B Biointerfaces 2022; 218:112781. [PMID: 36007313 DOI: 10.1016/j.colsurfb.2022.112781] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2022] [Revised: 08/11/2022] [Accepted: 08/16/2022] [Indexed: 11/26/2022]
Abstract
Glycyrrhetinic acid is a bioactive compound extracted from licorice that exhibits inhibition effect on various cancers. However, its hydrophobicity results in low bioavailability that limits application. We aim to overcome this barrier, the present research was performed to prepare glycyrrhetinic acid proliposomes mediated mannosylated ligand (mannose-diester lauric diacid-cholesterol, MDC) and to evaluate its physicochemical characterizations, environmental stability and bioactivity. In preliminary optimization studies of glycyrrhetinic acid proliposomes mediated MDC (MDC-GA-PL), four optimum operating parameters, cryoprotectant of glucose and mannitol, the mixed cryoprotectant ratio (glucose/mannitol) of 1:1, a cryoprotectant/egg phosphatidylcholine mass ratio of 10/1, and -60 ℃ pre-freezing temperature, were obtained after investigation. Under the optimum lyophilization conditions, MDC-GA-PL was freeze-dried and reconstituted proliposomes were characterized. These proliposomes showed that MDC-GA-PL were well-dispersible spherical particles with an average particle size of 120.80 nm, a polydispersity index about 0.095, a zeta potential of -33.15 mV, encapsulation efficiency of 85.9% and drug loading of 6.38%. In vitro drug release study showed that glycyrrhetinic acid release of MDC-GA-PL conforms to the Higuchi release model. In addition, these proliposomes were stable during six months at 4 ℃. Moreover, acute toxicity assay revealed no substantial safety concern for MDC-GA-PL. Finally, in vitro bioactivity of proliposomes was evaluated. Cytotoxicity effect and apoptosis efficiency of MDC-GA-PL by HepG2 cells was significantly higher than that of glycyrrhetinic acid proliposomes without MDC, demonstrating that MDC has a desirable effect on liver target. Overall, we have reason to believe that MDC-GA-PL would be a promising target delivery to improve therapeutic against hepatic diseases.

Abstract
Natural-based nanocomposites are competitive and promising materials for biomedical applications due to their biocompatibility. Herein, a novel natural-based composite was fabricated by alternately depositing lysozyme (LY) and albumin egg (AE) on electrospun cellulose nanofibrous mats via layer-by-layer self-assembly (LBL) technology. To indicate the successful deposition process and investigate the variations of the mats during LBL process, the surface morphology, physical property, chemical composition, wetting behavior and thermal stability were systematically studied. The results showed that the surface morphology and composition of the mats were significantly influenced by LBL process, which further resulted in the variation of wetting behavior. Besides, the mechanical properties were enhanced after LBL modification. In addition, the LBL structured nanofibrous mats exhibited antibacterial activity and excellent biocompatibility with L929 fibroblasts. In brief, LY and AE coated LBL structured cellulose nanofibrous mats, especially the 15 bilayers coated mats, have considerably potential applications in the biomedical field.
