Home parenteral nutrition (HPN) is a life-saving therapy for patients who are not able to use their gastrointestinal tract. There are a number of complications associated with HPN, including metabolic bone disease, intestinal failure-associated liver disease (IFALD), and catheter-related bloodstream infections. We present a case of a 32-year-old HPN patient who initially developed biopsy-proven IFALD (total bilirubin, 2.4 mg/dL) while on long-term HPN. His HPN was initiated due to myopathic intestinal dysmotility and pseudo-obstruction when he was 15 years old...

The stability of active compounds encapsulated in nanoparticles depends on the resistance of the particles to diffusion of environmental degradation agents. In this paper, off-lattice Monte Carlo simulations are used to investigate a suspension of nanostructured lipid carriers (NLC) composed of interspaced liquid and solid lipid domains, immersed in a solution containing molecules representing oxidative or other degradation agents. The simulations examine the diffusion of the degradation agents into the nanoparticles as a function of nanoparticle size, solid domain fraction, and domain size...

Jiayi Yang, Youling L Xiong
This study aimed to investigate the relative reaction rate of protein and lipid oxidation in different biphasic model systems (linoleic acid; liposome; emulsion) containing myofibrillar protein (MFP at 1, 8 and 20 mg/mL) under hydroxyl radical stress. Protein oxidation markers exhibited significant changes in 2 h: reduced tryptophan fluorescence intensity, carbonyl formation, and extensive polymerization of myosin. In contrast, no detectable changes (P > .05) in lipid peroxide occurred within 2 h except for samples with 1 mg/mL MFP which showed an early TBARS formation...

Efforts to develop a treatment for bupivacaine cardiotoxicity led to the discovery that Intralipid, a popular brand of intravenous lipid emulsion, could be used not only as an effective treatment for anesthetic-induced cardiac arrest, but also as a means of reversing many other toxicities. Contradictory data exist regarding the mechanism of action of lipid emulsion, a combination of fatty acids traditionally used in parenteral nutrition. Some researchers attribute the effects to lipophilicity and the individual characteristics of the lipids, while other data demonstrate a direct empowering mechanism through cellular upstream and downstream pathways...

INTRODUCTION: Liposome supported peritoneal dialysis is a recently described technique which may eventually be applicacle in the clinical scenario of the intoxicated patient. We evaluated the hypothesis that intravenous injection lipid emulsion (ILE) would augment acidic pH gradient liposome supported peritoneal dialysis (LSPD). METHODS: Orogastrically amitriptyline dosed rats were treated with either NaHCO3 intravenously and standard intraperitoneal dialysate (A); NaHCO3 intravenously and LSPD (B); or ILE and LSPD (C)...

The behaviour of proteins (β-lactoglobulin (βlg) and soy protein isolate (SPI)) and a surface active polysaccharide (hydroxypropylmethylcellulose, HPMC) o/w interfacial films under simulated gastrointestinal conditions using the interfacial tensiometer Octopus were compared and related to the performance of the emulsions (using the same emulsifiers) under in vitro digestion. The evolution of interfacial tension (γ) was used to investigate the effect of gastrointestinal fluids on o/w interfacial films. Clear differences were observed among these emulsifiers...

BACKGROUND: Renal protection is a critical concept for anesthesiologists, nephrologists, and urologists, since anesthesia and renal function are highly interconnected and can potentially interfere with one another. Therefore, a comprehensive understanding of anesthetic drugs and their effects on renal function remains fundamental to the success of renal surgeries, especially transplant procedures. Some experimental studies have shown that some anesthetics provide protection against renal ischemia/reperfusion (IR) injury, but there is limited clinical evidence...

BACKGROUND: Significant efforts have been made to improve the nutritional support of very preterm infants. Large surveys may help to know the nutritional practices for preterm infants in neonatal units and identify if they are in line with the current guidelines. METHODS: A multicentre nationwide web-based survey on clinical feeding practices in very low birth weight (VLBW) infants was conducted in tertiary neonatal hospitals that admit infants with a birth weight < 1,500 g and/or a gestational age of < 32 weeks...

This study determined feasibility of krill protein isolated with isoelectric solubilization/precipitation (ISP) as wall material to microencapsulate krill oil by freeze-drying. Effects of krill oil/krill protein ratio on properties of microcapsules were investigated. With increased ratio, crude protein of microcapsules decreased, while total lipid increased. Although microcapsule oil loading capacity increased, loading and encapsulation efficiencies decreased. Thin layer chromatography (TLC) confirmed abundance of phospholipids, which are amphiphilic; and thus, resulted in stable emulsion (emulsion stability index)...

REVIEW
David Julian McClements
Many researchers are currently developing emulsion-based delivery systems to increase the bioavailability of lipophilic bioactive agents, such as oil-soluble vitamins, nutraceuticals, and lipids. Oil-in-water emulsions can be specifically designed to improve the bioavailability of these bioactives by altering their composition and structural organization. This article reviews recent progress in understanding the impact of emulsion properties on the bioaccessibility of lipophilic bioactive agents, including oil phase composition, aqueous phase composition, droplet size, emulsifier type, lipid physical state, and droplet aggregation state...

Enterocyte apoptosis induced by lipid emulsions is a key cause of intestinal atrophy under total parenteral nutrition (TPN) support, and our previous work demonstrated that olive oil lipid emulsion (OOLE) could induce enterocyte apoptosis via CUGBP, Elav-like family member 1 (CELF1)/ apoptosis-inducing factor (AIF) pathway. As TPN-associated complications are partially related to choline deficiency, we aimed to address whether choline supplementation could attenuate OOLE-induced enterocyte apoptosis. Herein we present evidence that supplementary choline exhibits protective effect against OOLE-induced enterocyte apoptosis both in vivo and in vitro...

HYPOTHESIS: Amphiphilic character of surfactants drives them at the interface of dispersed systems, such as emulsions. Hemicellulose-rich wood extracts contain assemblies (lignin-carbohydrate complexes, LCC) with natural amphiphilicity, which is expected to depend on their chemical composition resulting from the isolation method. Lignin-derived phenolic residues associated with hemicelluloses are hypothesized to contribute to emulsions' interfacial properties and stability. EXPERIMENTS: We investigated the role of phenolic residues in spruce hemicellulose extracts in the stabilization of oil-in-water emulsions by physical and chemical approach...

Andrographolide is a major diterpenoid of Andrographis paniculata and possesses several biological activities, including protection against oxidative stress mediated neurotoxicity, inflammation-mediated neurodegeneration, and cerebral ischemia. However, this molecule shows low bioavailability, poor water solubility, and high chemical and metabolic instability. The present study reports preparation of solid lipid nanoparticles (SLN) to deliver andrographolide (AG) into the brain. SLN were prepared using Compritol 888 ATO as solid lipid and Brij 78 as surfactant and applying emulsion/evaporation/solidifying method as preparative procedure...

Three decades after the discovery, hepatitis C virus (HCV) is still the leading cause of liver transplantation and poses a major threat to global health. In spite of recent advances in the development of direct acting antivirals, there is still a need for a prophylactic vaccine to limit the virus spread and protect at-risk populations, especially in developing countries, where the cost of the new treatments may severely limit access. The use of recombinant HCV glycoproteins E1E2 (rE1E2) in combination with the MF59, an oil-in-water emulsion-based adjuvant, has previously been shown to reduce the rate of chronicity in chimpanzees and to induce production of cross-neutralizing antibodies and cellular immune responses in human volunteers...

The relative uptake and mechanisms of lipid-based emulsions of three different particle diameters by Caco-2 cells were studied. The corn oil-sodium caseinate emulsions showed little or no cytotoxicity even at 2 mg/mL protein concentration for any of the three droplet size emulsions. Confocal laser scanning microscopy (CLSM) of Nile red containing emulsions showed that the lipid-based emulsions were absorbed by Caco-2 cells. A negative correlation between the mean droplet size and cellular uptake was observed...
