HYPOTHESIS: The complete removal of remaining polymer debris after stripping of optical fiber cables is essential for high precision connection between two fibers. It can be anticipated that electrospun porous membranes as cleaning wipes are able to trap and retain polymer debris within their pores. Impregnation of an oil-in-water emulsion as cleaning agent lowers the interfacial tension between debris and the optical fiber thereby enabling the straightforward removal of polymer debris from the optical fiber...

Anxiety disorders are one of the most common mental health problems worldwide, but the exact pathophysiology remains largely unknown. It has been demonstrated previously that administration of exogenous ketone supplement KSMCT (ketone salt/KS + medium chain triglyceride/MCT oil) by intragastric gavage for 7 days decreased the anxiety level in genetically absence epileptic Wistar Albino Glaxo/Rijswijk (WAG/Rij) rats. To investigate the potential role of the adenosinergic system in the pathomechanism of anxiety we tested whether the inhibition of adenosine A1 receptors (A1 Rs) influence the anxiolytic effect of the exogenous ketone supplement...

The clinical application of disulfiram (DSF) in cancer treatments is hindered by its rapid degradation in the blood circulation. In this study, methoxy poly(ethyleneglycol)-b-poly(lactide-co-glycolide)/poly(ε-caprolactone) (mPEG5k-b-PLGA2k/PCL3.4k) micelles were developed for encapsulation of DSF -by using the emulsification-solvent diffusion method. Medium chain triglyceride (MCT) was incorporated into the mixed polymeric micelles to improve drug loading by reducing the core crystallinity. Differential scanning calorimetry (DSC) results implied that DSF is likely present in an amorphous form within the micelles, and is well dispersed...

RATIONALE: Primary intestinal lymphangiectasia (PIL) is a rare, presumably congenital lesion that is usually diagnosed in patients < 3 years old, is rarely first diagnosed in adulthood, and when first diagnosed in adulthood typically presents with symptoms for many years. Although PIL is often identified by endoscopic abnormalities, it must be emphasized that the jejunoileum/distal duodenum must be intubated for diagnosis because the lesions are present in these regions. This work demonstrates that 1)-PIL can occur in an octogenarian; 2)-shows that the characteristic endoscopic findings are not found at colonoscopy without terminal ileal intubation; and 3)-may be missed at standard EGD without distal duodenal intubation...

Fatty acid oxidation disorders (FAODs) and carnitine shuttling defects are inborn errors of energy metabolism with associated mortality and morbidity due to cardiomyopathy, exercise intolerance, rhabdomyolysis, and liver disease with physiologic stress. Hypoglycemia is characteristically hypoketotic. Lactic acidemia and hyperammonemia may occur during decompensation. Recurrent rhabdomyolysis is debilitating. Expanded newborn screening can detect most of these disorders, allowing early, presymptomatic treatment...

Monounsaturated (MUFA) fatty acids have been shown to induce greater meal-induced thermogenesis (MIT) than saturated fatty acids (SFA) in some studies, however, the effect of SFA chain length has not been examined. We hypothesized that a meal rich in short- to medium-chain SFA would elicit a greater MIT than one rich in long-chain SFA, and that MIT responses would be comparable between the short- to medium-chain SFA and the MUFA rich meal. A 3-arm crossover study was conducted with healthy overweight men, aged 18 to 40 years...

Lipid production by oleaginous Yarrowia lipolytica depends highly on culture environments, such as carbon sources, carbon/nitrogen (C/N) ratios, types of media, and cellular growth phases. In this study, the effects of media and carbon sources on lipid and metabolite production were investigated by profiling fatty acids and intracellular metabolites of Y. lipolytica grown in various media. The highest total fatty acid yield 114.04 ± 6.23 mg/g dry cell weight was achieved by Y. lipolytica grown in minimal medium with glycerol (SCG) in the exponential phase...

Systemic sclerosis (SSc) is a chronic systemic disease characterized by microvasculopathy, autoantibodies, and extensive fibrosis. Intestinal involvement is frequent in SSc and represents a significant cause of morbidity. The pathogenesis of intestinal involvement includes vascular damage, nerve dysfunction, smooth muscle atrophy, and fibrosis, causing hypomotility, which leads to small intestinal bacterial overgrowth (SIBO), malabsorption, malnutrition, diarrhea, pseudo-obstruction, constipation, pneumatosis intestinalis, and fecal incontinence...

A ketogenic diet (KD) is a normocaloric diet composed by high fat (80-90%), low carbohydrate, and low protein consumption that induces fasting-like effects. KD increases ketone body (KBs) production and its concentration in the blood, providing the brain an alternative energy supply that enhances oxidative mitochondrial metabolism. In addition to its profound impact on neuro-metabolism and bioenergetics, the neuroprotective effect of specific polyunsaturated fatty acids and KBs involves pleiotropic mechanisms, such as the modulation of neuronal membrane excitability, inflammation, or reactive oxygen species production...

The development of plant-based foods and beverages is becoming increasingly popular because of growing consumer concerns about perceived ethical, health, and environmental issues. The current study examined the influence of oil droplet concentration on the physicochemical properties of oil-in-water (O/W) emulsions stabilized with a plant-based surfactant. Emulsions were utilized as model creamers, which consisted of medium chain triglycerides (MCT) as the oil phase and quillaja saponin as a plant-based surfactant...

Tocotrienols have been reported to have stronger bioactivities than tocopherols, and may therefore be suitable as a potent source of vitamin E in functional foods, supplements, and pharmaceuticals. However, their inclusion into new products is hindered by their low water-solubility and oral bioavailability. Oil-in-water emulsions (O/W) could provide an adequate delivery system for these bioactive compounds. Tocotrienols were tested in bulk oil and within O/W conventional emulsions (>10μm) and nanoemulsions (<350nm)...

Lipid transmethylation methods described in the literature are not always evaluated with care so to insure that the methods are effective, especially on food matrix or biological samples containing polyunsaturated fatty acid (PUFA). The aim of the present study was to select a method suitable for all lipid species rich in long chain n-3 PUFA. Three published methods were adapted and applied on individual lipid classes. Lipid (trans)methylation efficiency was characterized in terms of reaction yield and gas chromatography (GC) analysis...

BACKGROUND: Children with long-chain fatty acid β-oxidation disorders (LCFAOD) presenting with clinical symptoms are treated with a specialist infant formula, with medium chain triglyceride (MCT) mainly replacing long chain triglyceride (LCT). It is essential that the safety and efficacy of any new specialist formula designed for LCFAOD be tested in infants and children. METHODS: In an open-label, 21-day, phase I trial, we studied the safety of a new MCT-based formula (feed 1) in six well-controlled children (three male), aged 7-13 years (median 9 years) with LCFAOD (very long chain acyl CoA dehydrogenase deficiency [VLCADD], n=2; long chain 3-hydroxyacyl CoA dehydrogenase deficiency [LCHADD], n=2; carnitine acyl carnitine translocase deficiency [CACTD], n=2)...

Medium Chain Triglycerides (MCT) is a dietary supplement and usually used along with medications for treating food absorption disorders including diarrhea, steatorrhea and liver disease. It has been shown that MCT plays a role in lowering weight, and decreasing metabolic syndrome, abdominal obesity and inflammation. However, it is still unknown whether MCT enhances exercise endurance. Here, we demonstrated that MCT containing diet improves high temperature induced exercise performance impairment. We found that MCT up-regulates the expression and protein levels of genes involved in mitochondrial biogenesis and metabolism...

BACKGROUND: Cholestasis is a common complication in infants receiving prolonged parenteral nutrition (PN). We studied the effects of two intravenous lipid emulsions composed with either 30% soybean oil, 30% medium-chain triglycerides (MCT), 25% olive oil, and 15% fish oil (SMOF) or with 50% MCT and 50% soybean oil n-6 (MCT/SOY) on the incidence of cholestasis in surgical term and near-term neonates. METHODS: A single-center, double-blinded, randomized controlled trial compared the incidence of cholestasis using either SMOF or MCT/SOY in neonates born at gestational age ≥34 weeks undergoing major surgery...

The goal of this project was to create hydrogels, a type of soluble biopolymer delivery system to encapsulate flavored nanoemulsions that are released under artificial saliva conditions. Low methoxyl (LM) pectin and whey protein isolate (WPI) at pH 4.0 were used to form the hydrogels at a ratio of 4:1 (w/w), respectively. Orange oil, medium-chain triglyceride (MCT) oil, and WPI were used to make stable nanoemulsions loaded with flavor oil. The nanoemulsions were encapsulated into hydrogels with a mean diameter of 768 ± 36 nm...

Emulsion filled protein (EFP) gels were prepared through a cold-set gelation process using denatured protein, and the effects of fat substitutes on the texture and volatile release of EFP gels were investigated. Pre-heating determined the denature degree of protein structure, and higher heating intensity resulted in higher viscosity of the emulsions, and larger storage modulus (G') of the corresponding gels. Oil-reduced EFP gels (15% sunflower oil) were prepared with the addition of fat substitutes (medium chain triglyceride-MCT, maltodextrin, or guar gum), and they showed different properties from the full-oil counterpart (20% sunflower oil)...

Human milk is recommended for feeding preterm infants. The current pilot study aims to determine whether breast-milk lipidome had any impact on the early growth-pattern of preterm infants fed their own mother's milk. A prospective-monocentric-observational birth-cohort was established, enrolling 138 preterm infants, who received their own mother's breast-milk throughout hospital stay. All infants were ranked according to the change in weight Z-score between birth and hospital discharge. Then, we selected infants who experienced "slower" (n = 15, -1...
