The purpose of this study was to investigate the feasibility of an intravenously administered combinational therapy using lipid nanocapsules (LNCs) as a drug delivery carrier for the treatment of different cancers. Therefore, we encapsulated 6 anticancer drugs within LNCs. Their size was approximately 50 nm. Except for oxaliplatin, their encapsulation efficiency, which was measured by different analytical methods, varied between 75% for SN38 to 100% for regorafenib. The in vitro studies showed a nonsignificant difference between the cytotoxicity of free and encapsulated drugs and a significant decrease in haemolysis by encapsulation in LNCs. Finally, the in vivo experiment showed that a combinational regimen of SN38-LNCs and regorafenib-LNCs abates CT26 murine colorectal cancer growth and increases median survival time.

Controlling microbial pollutants is a significant public health concern as they cause several chronic microbial infections and illnesses. In recent years, essential oils (EOs) have become intriguing alternatives for synthetic antimicrobials due to their biodegradability, natural source extraction, and strong antibacterial properties. The bactericidal properties of alginate containing lemon essential oil were examined in this investigation.

This work explores two methods to encapsulate Thymoquinone (TQ) into lipid nanocapsules (LNCs) for oral administration. TQ was added during the phase inversion temperature method (TQ-LNCs-1) or to unload LNCs dispersion (TQ-LNCs-2). LNCs were evaluated for mean diameter, polydispersity index (PDI), ζ-potential, drug loading (DL), drop tensiometer, storage stability, stability in simulated gastrointestinal fluids (SGIF), and intestinal permeability across Caco-2 cells.

Developing and creating novel antibiotics is one of the most important targets in treating infectious diseases. Novel coumarins were synthesized and characterized using different spectroscopic techniques such as Fourier Transform Infrared (FTIR), Nuclear magnetic resonanceH and C and mass spectroscopy (MS). All of the synthesized compounds have been tested for activity and sensitivity against the microbial strains of B.

This study was executed to mitigate imiquimod (IMQ)-side effects and promote its anticancer potential against skin cancer via encapsulation in hyaluronic acid-coated lipid nanocapsules (HA-LNCs) for targeted topical delivery. The LNCs were prepared using the phase inversion technique. Optimized LNCs formulation was gained following 2 factorial design experiment to adjust the IMQ and CTAB concentrations.
