Microchannel (MC) emulsification for the preparation of monodisperse oil-in-water (O/W) and water-in-oil-in-water (W/O/W) emulsions containing palm oil as the oil phase was investigated for application as basic material solid/semi-solid lipid microspheres for delivery carriers of nutrients and drugs. Emulsification was characterized by direct observation of droplet generation under various operation conditions, as such, the effects of type and concentration of emulsifiers, emulsification temperature, MC structure, and flow rate of to-be-dispersed phase on droplet generation via MC were investigated. Sodium caseinate (SC) was confirmed as the most suitable emulsifier among the examined emulsifiers, and monodisperse O/W and W/O/W emulsions stabilized by it were successfully obtained with 20 to 40 µm mean diameter () using different types of MCs.

Background: Foot-and-mouth disease (FMD) causes significant economic losses, prompting vaccination as a primary control strategy. Virus-like particles (VLPs) have emerged as promising candidates for FMD vaccines but require adjuvants to enhance their immunogenicity. In this study, we evaluated the immunogenicity of a VLP-based vaccine with a water-in-oil-in-water (W/O/W) emulsion adjuvant, named WT.

Background: Given the risks associated with autologous bone transplantation and the limitations of allogeneic bone transplantation, scaffolds in bone tissue engineering that incorporate bioactive peptides are highly recommended. Teriparatide (TPTD) plays a significant role in bone defect repair, although achieving controlled release of TPTD within a bone tissue engineering scaffold remains challenging. This work reports a new approach for treatment of teriparatide using a water-in-oil-in-water (w/o/w) microspheres be equipped on gelatin (GEL)/Poly lactic-glycolic acid (PLGA)/attapulgite (ATP) scaffold.

Bone defects are difficult to treat clinically and most often require bone grafting for repair. However, the source of autograft bone is limited, and allograft bone carries the risk of disease transmission and immune rejection. As tissue engineering technology advances, bone replacement materials are playing an increasingly important role in the treatment of bone defects.

Chicken yolk immunoglobulin (IgY) is a natural immunologically active antibody extracted from egg yolk and can be used as a natural dietary supplement for the treatment of inflammation and damage to the intestines. In our study, IgY was embedded in a double emulsion (W/O/W; DE) to explore the therapeutic effect of the embedded IgY on Lipopolysaccharide (LPS)-induced jejunal injury in mice. The results showed that W/O/W-embedded IgY as a dietary supplement (IgY + DE) attenuated LPS-induced damage to mouse small intestinal structures and protected the integrity of the jejunal mucosal barrier.

Triple-negative breast cancer (TNBC) presents with resistance phenotypes to certain therapies, such as cisplatin, often requiring higher dosing, with associated acquired tumor resistance, renal toxicity, and variable patient responses. A self-emulsifying drug delivery (SEDD) formulation approach was proposed to overcome the limitations of cisplatin in TNBC, focusing on improving intracellular cisplatin and control siRNA uptake as a proof-of-principle of dual drug delivery. Four SEDD formulations were prepared and optimized for cisplatin (o/w) emulsion and FITC-siRNA (w/o) emulsion using pseudo-ternary phase diagrams to facilitate the formation of water-in-oil-water (w/o/w) emulsions.
