the purpose of this study was to produce oil in water nano-emulsion by ultrasonication, and investigate the influence of inulin and β-cyclodextrin on the prosperities of nano-emulsion and morphology of spray dried microcapsules. the results showed that emulsion droplet size in samples containing β-cyclodextrin (8.28±0.11 nm) was less than inulin samples (97.12±4.2 nm). considering sem photos, β...

Dietary n-3 fatty acids (FAs) may reduce cardiovascular disease risk. We questioned whether acute administration of n-3 rich triglyceride (TG) emulsions could preserve cardiac function and decrease injury after ischemia/reperfusion (I/R) insult. We used two different experimental models: in vivo, C57BL/6 mice were exposed to acute occlusion of the left anterior descending coronary artery (LAD),...

Antioxidant potential of the fungal dye, produced by a strain selected from the collection of Epicoccum nigrum bioresearch platform (acronym MIUG) was partially characterized in previous studies. However, the fungal dye antioxidant capacity compared with other potential colorant inhibitors of lipid peroxidation (e.g. cochineal dye) has not been fully elucidated, especially regarding its behavio...

The present investigation involves formulation and evaluation of microspheres with Repaglinide as model drug for prolongation of drug release time. An attempt was made to prepare microspheres of Repaglinide by Quasi emulsion solvent diffusion technique, with a view to deliver the drug at sustained or controlled manner in gastrointestinal tract and consequently into systemic circulation. The mic...

introduction: hydrocolloids are widely used in food systems as an emulsifying or stabilizing agent. one way to improve the emulsifying properties of hydrocolloids is complexation with proteins. in general, protein and hydrocolloid components may be combined together by either a) covalent bonding (conjugates) or b) electrostatic complexing. conjugates can be efficiently prepared during the stora...

two steps synthetic method for the preparation of a novel emulsion stabilizer called poly(ricineoleic acid-b-ethyleneglycol-b-ricineoleic acid) with average mass molecular weight of 7000 daltons is investigated. in the first step, oligoricineoleic acid with average mass molecular weight of 1800 daltons is synthesized (yield 70%). in the second step, the desired copolymer is  synthesized from th...

the oil refining industries are using a number of demulsifiers for dewatering and desalination of crude oil but experience has shown that universal demulsifiers can not be produced. each kind of water in oil (w/o) emulsion requires specific by composition demulsifier. in practice, synergetic effect of the interaction between different types of demulsifiers is often sought. for dewatering the w...

Microencapsulation as one of the most modern methods has remarkable effects on probiotic survival. In this study Lactobacillus casei (ATCC 39392) and Bifidobacterium bifidum (ATCC 29521) were encapsulated using calcium alginate-gelatinized starch, chitosan coating and inulin via emulsion technique, and were incubated in simulated gastric juice (along with pepsin, pH=1.5) and simulated intestina...

Background: Intravenous drug delivery is an advantageous choice for rapid administration, immediate drug effect, and avoidance of first-pass metabolism in oral drug delivery. In this study, the synthesis, formulation, and characterization of atorvastatin-loaded polyurethane (PU) nanoparticles were investigated for intravenous route of administration. Method: First, PU was synthesized and charac...
