A I Parfenov, L M Krums
Protein-losing enteropathy (PLE) is a rare complication of intestinal diseases. Its main manifestation is hypoproteinemic edema. The diagnosis of PLE is based on the verification of protein loss into the intestinal lumen, by determining fecal α1-antitrypsin concentration and clearance. The localization of the affected colonic segment is clarified using radiologic and endoscopic techniques. The mainstay of treatment for PLE is a fat-free diet enriched with medium-chain triglycerides. Surgical resection of the affected segment of the colon may be the treatment of choice for severe hypoproteinemia resistant to drug therapy...

This study aims to investigate the transport of lipid nano-droplets through MDCK epithelial cell monolayer. Nanoemulsions of self-nano-emulsifying drug delivery systems (SNEDDS) labeled with radioactive C18 triglyceride were developed. The effect of droplet size and lipid composition on the transport was investigated. The results showed that the lipid nano-droplet transport through MDCK cell monolayer was as high as 2.5%. The transport of lipid nano-droplets was higher for nanoemulsions of medium chain glycerides than the long chain glycerides...

The ketogenic diet (KD) is a cheap and effective alternative therapy for most epilepsy. There are paucity of experimental data in Nigeria on the usefulness of KD in epilepsy models. This is likely to be responsible for the poor clinical acceptability of the diet in the country. This study therefore aimed at providing experimental data on usefulness of KD on seizure models.  The study used 64 Wistar rats that were divided into two dietary groups [normal diet (ND) and ketogenic diet (KD)]. Animal in each group were fed for 35days...

REVIEW
Sara Tucci
Very-long-chain-acyl-CoA-dehydrogenase deficiency is the most common disorder of mitochondrial long-chain fatty acid (LCFA) oxidation, with an incidence of 1:50,000-1:100,000 in newborns. Catabolic situations contribute to the aggravation of symptoms and induce severe metabolic derangement. Treatment for VLCAD-deficiency includes avoidance of fasting and a long-chain fat-restricted and fat-modified diet in which LCFAs are fully or partially replaced by medium-chain triglycerides (MCT). The aim of this work was to investigate the outcome and the effects of long-term treatment in a mouse model of VLCAD-deficiency...

Melatonin, the major pineal secretory product, has a significant impact on the female reproductive system. Recently, the beneficial effects of melatonin on mammalian oocyte maturation and embryonic development have drawn increased attention. However, the exact underlying mechanisms remain to be fully elucidated. This study demonstrates that supplementing melatonin to in vitro maturation (IVM) medium enhances IVM rate, lipid droplets (LDs) accumulation as well as triglyceride content in porcine oocytes. Decrease of mitochondrial membrane potential, mitochondrial respiratory chain complex IV activity as well as mitochondrial reactive oxygen species (mROS) content indicated that melatonin induced a decrease of mitochondrial activity...

Cholesterol and lipid homeostasis is important for male fecundity. However, the plasma total cholesterol level does not reflect sperm concentration and motility. Adipose tissue in mammals is the main tissue contributing to the dynamic equilibrium of lipid synthesis and catabolism. However, recent studies suggested that local lipolysis has an important role in male fertility. If so, which plasma lipid metabolism parameter reflects sperm concentration and motility? Leptin receptor-deficient db/db mice show hyperphagia, hyperglycemia, hypercholesterolemia, hypertriglyceridemia, morbid obesity and are reported to be infertile...

Hydrochlorothiazide (HCTZ) is a class IV drug according to the Biopharmaceutical Classification System. This study aimed the development of self-nanoemulsifying drug delivery system (SNEDDS) for HCTZ as an approach to overcome the biopharmaceutical limitations. Pre-formulation screening and ternary phase diagrams were carried out to select the oil phase, the surfactant, and the co-surfactant as the amount of each constituent. The optimized formulations, with reduced amount of surfactant, and composed of medium chain triglycerides, Cremophor EL and Transcutol P did not affect the pH or show drug incompatibilities...

Brain glucose uptake declines during aging and is significantly impaired in Alzheimer's disease. Ketones are the main alternative brain fuel to glucose so they represent a potential approach to compensate for the brain glucose reduction. Caffeine is of interest as a potential ketogenic agent owing to its actions on lipolysis/ lipid oxidation but whether it is ketogenic in humans is unknown. This study aimed to evaluate the acute ketogenic effect of two doses of caffeine in healthy adults (2.5; 5.0 mg/kg) during a 4-hour metabolic study period...

Lipids are very important for human health and milk is a rich dietary source of lipids. In this study, the lipid content in three types of milk (goat, soy and bovine) were determined by using UPLC-Q-Exactive Orbitrap Mass Spectrometry. A total of 13 classes of lipids (including Cer, SM, LPC, PC, PE, DG, TG, PA, PG, PI, PS, LPE, FA) were measured. Moreover, lipid profiles differed significantly between the different milk types. Soymilk is rich in phospholipids including PC, PE, PS, PG, while goat milk is rich in medium chain triglycerides (MCT), USFA, ω-6 FA and ω-3 FA, especially EPA and DHA...

BACKGROUND & AIMS: Intravenous lipid emulsions (IVLEs) are a key component in long-term home parenteral nutrition (HPN), providing energy and essential fatty acids (EFAs). Modification of the fatty acid (FA) composition of IVLEs may lead to changes in metabolic responses and cell and tissue function, providing opportunity for clinical improvements. Studies have suggested that, in place of conventional pure soybean oil (SO)-based IVLEs, which have a high omega-6 FA content, alternative IVLEs with different FA profiles may have beneficial effects...

We report the case of a 13-month-old girl with frequent vomiting, intractable diarrhea, hyperlactatemia, and liver dysfunction. Although the symptoms were treatment resistant, enteral nutrition formula containing medium-chain triglycerides reduced the weight loss, vomiting, and diarrhea. Immunostaining of mitochondrial respiratory chain (MRC) complexes of the colonic mucosa confirmed the diagnosis of MRC complex I deficiency. This case shows that this disease should be included in the differential diagnosis of hyperlactatemia and intractable, cryptogenic gastrointestinal symptoms...

Citrin deficiency, an inherited defect of the liver-type mitochondrial aspartate/glutamate carrier isoform (citrin), may cause impairment of glycolysis because of an increase in the cytosolic NADH/NAD(+) ratio. We report a Japanese boy whose main complaint was recurrent hypoglycemic episodes. He was suspected as having citrin deficiency because of his peculiar preference for protein- and fat-rich food. His young sister also had a similar food preference. Both siblings were diagnosed with citrin deficiency by genetic analysis...

Chylous ascites is a very rare occurrence in a patient with gallbladder cancer (GBC), and only six cases have been reported. We report here one such case in a 55-year-old lady who presented to us with upper abdominal pain for 6 months. A polypoidal gallbladder mass with minimal liver invasion but with multiple subcentimeter pericholedochal, common hepatic, mesenteric, and para-aortic lymph nodes was found on contrast-enhanced computed tomography scan. At laparotomy, the abdomen had milky fluid with engorged beaded lymphatics all over the small intestine...
