Effect of Octyl Salicylate With Respect To the Physical Appearance of Mono/Di Caprylic and Capric Fatty Acids Formulations

Caprylic and capric acids are classified as medium-chain fatty acids. In this study, the behavior of the caprylic and capric acids formulations containing octyl salicylate were investigated. The formulations were prepared using homogenization proses. The characteristics of the formulation such as particle size, flow behavior, microscopic view and absorbance of the formulations were investigated. Particle sizes of the formulations were found ranging from 352.7 - 704.2 nm. The viscosity of the formulations changed as the shear rate was varied and could be classified as non-Newtonian fluids. The viscosity decreases when the fluid undergoes longer shear stress with time. The formulations containing octyl salicylate shows higher absorbance as compared to the formulations without octyl salicylate. The addition of octyl salicylate affected the system in terms of behavior, appearance and stability

Background: Cancer is one of the main causes of death by disease; several alternative treatments have been developed to counteract this condition. Curcumin (diferuloylmethane), extracted from the rhizome of Curcuma longa, has antioxidant, anti-inflammatory, and anti-cancer properties; however, it has low water solubility and poor intestinal absorption. Carrier systems, such as nanoemulsions, can increase the bioavailability of lipophilic bioactive compounds. Objective: To evaluate the effect of curcumin nanoemulsions prepared with lecithin modified with medium-chain fatty acids as an emulsifier, on the expression of the Cdk4, Ccne2, Casp8 and Cldn4 genes involved in the carcinogenesis process in K14E6 transgenic mice. Methods: The emulsifier was prepared by interesterification of medium-chain fatty acids, pure lecithin, and immobilized phospholipase-1 on Duolite A568. An Ultraturrax homogenizer and a Branson Ultrasonic processor were used for the preparation of nano-emulsions, and a Zetasizer evaluated the particle size. qRT-PCR analysis was performed to quantify the cancer-related genes expressed in the K14E6 mice. The development and evolution of skin carcinogenesis were assessed through histological analysis to compare cell morphology. Results: Ca 59% of the MCFA were incorporated via esterification into the PC within 12 hours of the reaction. An emulsifier yield used to formulate the NE of 86% was achieved. Nanoemulsions with a particle size of 44 nm were obtained. The curcumin nano-emulsion group had a 91.81% decrease in the tumorigenesis index and a reduction in tumor area of 89.95% compared to the sick group. Histological analysis showed that the group administered with free curcumin developed a microinvasive squamous cell carcinoma, as opposed to the group with nanoemulsion which presented only a slight inflammation. In gene expression, only a significant difference in Cdk4 was observed in the nanoemulsion group.

Abstract Background The ketogenic diet (KD) can promote the anti-inflammatory metabolic state and increase ketone body level in rats. This study was to explore the effects and differences of KD with or without medium-chain fatty acids (MCFAs) on serum inflammatory factors and mTOR pathway in Sprague–Dawley (SD) rats. Results Male SD rats were assigned to five groups: control diet (C), 20% caloric restriction diet (LC), 20% caloric restriction ketogenic diet (containing MCFAs) (LCKD1), 20% caloric restriction ketogenic diet (LCKD2) and 20% caloric restriction foreign ketogenic diet (LCKD3), and fed for 30 d. LC and KD could significantly reduce the body weight of rats; LC and KD containing MCFAs showed anti-inflammatory effects; KD without MCFAs decreased the concentration of mTOR1, while KD containing MCFAs decreased the expression of AMPK, mtor1 and P70sk. Conclusions KD containing MCFAs showed better effects on the mTOR pathway and anti-inflammation than that without MCFAs.
