Polyvinylpyrrolidone K30 was used as the templating agent, and ammonium bicarbonate was used as the pore-forming agent to make porous mannitol and porous lactose by the template and pore-forming agent method, respectively. Compared with the template method, the porous particles prepared by the pore-forming agent method have larger pore diameter (320.276 nm and 250.528 nm) and specific surface area (1.018 m/g and 0.913 m/g). The molecular docking results showed that mannitol/lactose interacted with curcumin and adhered to each other through hydrogen bonding. The adsorption kinetics process of porous mannitol and porous lactose prepared by template agent, pore-forming agent and curcumin were different. Among the curcumin-loaded porous particles prepared by the two methods, the curcumin-loaded porous lactose prepared by the pore-forming agent method had the fastest release rate and the highest cumulative release rate (95 %). Curcumin releases consistent with the Peppas release kinetics model and the diffusion mechanism.

The ApxIVA protein belongs to a distinct class of a "clip and link" activity of Repeat-in-ToXin (RTX) exoproteins. Along with the three other pore-forming RTX toxins (ApxI, ApxII and ApxIII), ApxIVA serves as a major virulence factor of Actinobacillus pleuropneumoniae, the causative agent of porcine pneumonia. The gene encoding ApxIVA is located on a bicistronic operon downstream of the orf1 gene and is expressed exclusively under in vivo conditions.

Introduction: This study aims to develop immediate release tablet formulations of lornoxicam (LRX) using hot melt extrusion (HME)-based fused deposition modeling (FDM) focusing on the adjustment of drug release by arranging infill densities and evaluating microcrystalline cellulose II (MCC II) as a disintegrating agent for HME-FDM purposes. LRX is a poorly soluble drug that exhibits pH-dependent solubility with a high thermal degradation temperature. These characteristics make it an ideal model drug for the HME-based FDM technique.
