PURPOSE OF REVIEW: The primary treatment for nonalcoholic fatty liver disease (NAFLD) in children is lifestyle change, including a healthier diet. However, there are no agreed upon expert recommendations for a specific diet in the prevention or treatment of NAFLD. In this study, we review studies published between 2015 and 2017 contributing to further understanding of the role of diet in the development and progression of NAFLD, particularly those addressing sugars and dietary patterns...

Obesity and absence of physical exercise are global problems that affect concentration and sperm quality in the male reproductive system. The purpose of this study was to examine the effect of obesity and resistance training, considered separately or in association, on testicular function and reproductive capacity. Twenty pubertal male Wistar rats were distributed into four groups: control (C) and exercise (E) groups that received standard rat chow; and obese (O) and obese with exercise (OE) groups that received a high-fat diet...

Elevated levels of reactive oxygen species (ROS) are a hallmark of obesity. Peroxiredoxin 5 (Prx5), which is a cysteine-dependent peroxidase enzyme, has an intensive ROS scavenging activity because it is located in the cytosol and mitochondria. Therefore, we focused on the role of Prx5 in regulating mitochondrial ROS and adipogenesis. We demonstrated that Prx5 expression was upregulated during adipogenesis and Prx5 overexpression suppressed adipogenesis by regulating cytosolic and mitochondrial ROS generation...

The 8-globulin-rich mung bean protein (MPI) suppresses hepatic lipogenesis in rodent models and reduces fasting plasma glucose and insulin levels in obese adults. However, its effects on mitigating high fat diet (HFD)-induced obesity and the mechanism underlying these effects remain to be elucidated. Herein, we examined the metabolic phenotype, intestinal bile acid (BA) pool, and gut microbiota of conventionally raised (CONV-R) male C57BL/6 mice and germ-free (GF) mice that were randomized to receive either regular HFD or HFD containing mung bean protein isolate (MPI) instead of the dairy protein present in regular HFD...

Probiotics such as Lactobacillus and Bifidobacterium improve the balance of intestinal microflora and have various physiological functions beneficial to human health. It is not always known whether the ingested microbial cells are viable- or killed. However, even sterilized bacterial cells are functional. Bacterial cell functions are strain-specific and their modes of action are still poorly understood. The aim of this study was to elucidate the roles of sterilized bifidobacteria in obesity and lipid metabolism...

Ironman triathlons are ultra-endurance events of extreme duration. The performance level of those competing varies dramatically, with elite competitors finishing in ~ 8:00:00, and lower performing amateurs finishing in ~ 14-15:00:00. When applying appropriate values for swimming, cycling and running economies to these performance times, it is demonstrated that the absolute energy cost of these events is high, and the rate of energy expenditure increases in proportion with the athlete's competitive level...

AIMS/HYPOTHESIS: Paternal high-fat diet prior to mating programmes impaired glucose tolerance in female offspring. We examined whether the metabolic consequences in offspring could be abolished by folate treatment of either the male rats before mating or the corresponding female rats during pregnancy. METHODS: Male F0 rats were fed either control diet or high-fat, high-sucrose and high-salt diet (HFSSD), with or without folate, before mating. Male rats were mated with control-diet-fed dams...

BACKGROUND/OBJECTIVES: Individuals with high pre-treatment bacterial Prevotella-to-Bacteroides (P/B) ratio have been reported to lose more body weight on diets high in fiber than subjects with a low P/B ratio. Therefore, the aim of the present study was to examine potential differences in dietary weight loss responses between participants with low and high P/B. SUBJECTS/METHODS: Eighty overweight participants were randomized (52 completed) to a 500 kcal/d energy deficit diet with a macronutrient composition of 30 energy percentage (E%) fat, 52 E% carbohydrate and 18 E% protein either high (≈1500 mg calcium/day) or low ( ≤ 600 mg calcium/day) in dairy products for 24 weeks...

BACKGROUND AND OBJECTIVE: Maternal overnutrition has been implicated in affecting the offspring by programming metabolic disorders such as obesity and diabetes, by mechanisms that are not clearly understood. This study aimed to determine the long-term impact of maternal high-fat (HF) diet feeding on epigenetic changes in the offspring's hypothalamic Pomc gene, coding a key factor in the control of energy balance. Further, it aimed to study the additional effects of postnatal overnutrition on epigenetic programming by maternal nutrition...

BACKGROUND: A high-protein diet in infancy increases the risk of obesity, but the effects of dietary protein intake in mid-childhood on body composition are unclear. Therefore, we studied associations of protein intake (total, animal and plant-sourced) at 8 years of age with anthropometric measures and body composition up to age 10 years. METHODS: We included 3991 children of the Generation R Study, a prospective cohort in the Netherlands. Dietary protein intake was assessed at 8 years of age using a food-frequency questionnaire and is expressed in energy percentage (E%)...

Maternal obesity has been reported to impair oocyte quality in mice, however, the underlying mechanisms remain unclear. In the present study, by conducting a comparative proteomic analysis, we identified a reduced expression of TIGAR protein in ovulated oocytes from high-fat diet (HFD)-fed mice. Specific depletion of TIGAR in mouse oocytes results in the marked elevation of reactive oxygen species (ROS) levels and the failure of meiotic apparatus assembly. Importantly, forced expression of TIGAR in HFD oocytes not only attenuates ROS production, but also partly prevents spindle disorganization and chromosome misalignment during meiosis...

The effects of triterpenic acids-enriched fraction from Cyclocarya paliurus (CPT) on nonalcoholic fatty liver disease (NAFLD) were investigated using in vivo and in vitro models. In high fat diet-induced Wister rats, CPT significantly increased superoxide dismutase (SOD) activity and glutathione/oxidized glutathione (GSH/GSSG) ratio, reduced malondialdehyde (MDA) and protein carbonyl (PCO) levels. Moreover, CPT restored mitochondrial membrane potential dysfunction, decreased cytochrome P450 enzyme 2E1 (CYP2E1) activity, improved nuclear factor erythroid 2-related factor 2 (Nrf2) and Nrf2-mediated antioxidant enzyme heme oxygenase1 (HO-1) expression...

Obesity due to excessive lipid accumulation is closely associated with metabolic diseases such as type 2 diabetes, insulin resistance and inflammation. Therefore, a detailed understanding of the molecular mechanisms that underlie adipogenesis is crucial to develop treatments for diseases related to obesity. Here, we found that the microRNA-204-5p (miR-204-5p) was expressed at low levels in fat tissues from obese mice fed long-term with a high-fat diet (HFD). Overexpression or inhibition of miR-204-5p in vitro in 3T3-L1 preadipocytes significantly inhibited or promoted 3T3-L1 proliferation, respectively, an effect mediated by regulating cell proliferation factors...

Thirty-eight percent of US adult women are obese, meaning that more children are now born of overweight and obese mothers, leading to an increase in predisposition to several adult onset diseases. To explore this phenomenon, we developed a maternal obesity animal model by feeding mice a diet composed of high fat/ high sugar (HF/HS) and assessed both maternal diet and offspring diet on the development of endometrial cancer (ECa). We show that maternal diet by itself did not lead to ECa initiation in wildtype offspring of the C57Bl/6J mouse strain...

Adipose tissue (AT) inflammation is crucial to the development of obesity-associated insulin resistance. Our aim was to investigate the contribution of COX-2/MIF-mediated crosstalk between hypertrophic adipocytes and macrophages to the etiology of AT inflammation and involvement of CD74 using human SGBS adipocytes, THP-1 macrophages and mice fed a high-fat (HF) diet. The MIF and CD74 mRNA levels in the adipocytes and SVCs (stromal vascular cells) of white fat were highly correlated with body weight, HOMA-IR and adipose macrophage marker expression levels, especially those in SVCs...

Protein arginine methyltransferase 5 (PRMT5) regulates gene expression either transcriptionallyly by symmetric dimethylation of arginine residues on histones H4R3, H3R8 and H2AR3, or at the post-translational level by methylation of non-histone target proteins. While emerging evidence suggests that PRMT5 functions as an oncogene, its role in metabolic diseases is not well defined. We investigated the role of PRMT5 in promoting high fat-induced hepatic steatosis. High fat diet up-regulated PRMT5 levels in the liver, but not in other metabolically relevant tissues such as skeletal muscle or white and brown adipose tissue...

Apart from the conventional hypolipidemic therapy, plaque regression through enhanced reverse cholesterol transport (RCT) has emerged as novel approach in atherosclerotic drug development. High-density lipoprotein (HDL) mimetics as well as agents that augment the functional HDL and RCT pathways are under intense exploration. Desmodium gyrans (Fabacea) has been shown to have hypolipidemic efficacy, with an HDL-enhancing property. In this study, a chromatographically purified active fraction of D. gyrans (DGMAF) significantly decreased the serum and lipid profiles as well as lipotoxicity in liver in Wistar rats fed with high-fat diet (HFD)...
