The aim of this study was to investigate the enhancement of all-trans retinoic acid (ATRA) loading in nano-lipid emulsions and stability by using oleic acid. The effect of formulation factors including initial ATRA concentration and the type of oil on the physicochemical properties, that is, percentage yield, percentage drug release, and photostability of formulations, was determined. The solubility of ATRA was increased in the order of oleic acid > MCT > soybean oil > water. The physicochemical properties of ATRA-loaded lipid emulsion, including mean particle diameter and zeta potential, were modulated by changing an initial ATRA concentration as well as the type and mixing ratio of oil and oleic acid as an oil phase. The particles of lipid emulsions had average sizes of less than 250 nm and negative zeta potential. The addition of oleic acid in lipid emulsions resulted in high loading capacity. The photodegradation rate was found to be dependent on the initial drug concentration but independent of the type of oily phase used in this study. The release rates were not affected by initial ATRA concentration but were affected by the type of oil, where oleic acid showed the highest release rate of ATRA from lipid emulsions.
Objective: To explore the differences in fat and fatty acids content between freshwater and saltwater fish.
Methods: The fat and fatty acids content in 83 fish meat samples from four regions(Hainan, Jiangsu, Fujian, and Guangxi) were detected by national standard method. Mann-Whitney U tests and t-tests were used to compare the differences in fat and major fatty acid content between freshwater and saltwater fish.
The unique fatty acid composition of BSF larvae oil makes it suitable for various applications, including use in animal feed, aquaculture, biodiesel production, biomaterials, and the food industry. Determination of BSF larvae composition usually requires analytical methods with chemicals, thus needing emerging techniques for fast characterization of its composition. In this study, Near Infrared Hyperspectral Imaging (NIR-HSI) (928 - 2524 nm) coupled with chemometrics was applied to predict the lipid content and fatty acid composition in intact black soldier fly (BSF) larvae.
Background: The nutritional value and health-promoting properties cause the fruits (acorns) of to have great potential for use in the food industry as functional ingredients and antioxidants source.
Objective: In this study, the amount of total phenolic compounds, flavonoids in different extracts (defatted, non-defatted) and composition of fatty acids in the fruits oils of were investigated. Besides, antioxidant activity was determined.
Oleic acid liposomes (OALs) are novel vesicular carriers ofunsaturated fatty acids and their corresponding ionized species, arranged within an enclosed lipid bilayer. This study aimed to encapsulate moxifloxacin HCl (MOX), a broad-spectrum antibacterial drug into OALs for effective treatment of Methicillin-resistant Staphylococcus aureus (MRSA) infection through topical application. Various OALs were formulatedby combining varied quantities of phosphatidylcholine (PC), oleic acid (OA), and cholesterol (CH) with 50 mg of MOX.
