Capsaicin (CAP), the major active component of chili peppers, is known to have thermogenic and weight-loss potential. The aim of this study was to investigate the anti-obesity effects of capsaicin-loaded nanoemulsions (C-NE) on male Sprague Dawley (SD) rats treated with a high-fat diet (HFD). The food grade C-NE was prepared using capsaicin, medium chain triacylglycerols (MCT) (Neobee 1053), sucrose stearate S-370, Tween 80 and distilled water with an emulsion droplet size of 168 nm and a capsaicin loading of 80...

Nonalcoholic fatty liver disease is growing in prevalence worldwide. It is started by the presence of macrosteatosis on liver histology but is often clinically asymptomatic. However, it can progress into nonalcoholic steatohepatitis which is a more severe form of liver disease characterized by inflammation and fibrosis. Further progression leads to cirrhosis, which predisposes patients to hepatocellular carcinoma or liver failure. The mechanism by which simple steatosis progresses to steatohepatitis is not entirely clear...

Chronic liver diseases (CLDs), due to chronic hepatitis C; hepatitis B; nonalcoholic fatty liver diseases (NAFLD); and alcoholic liver disease, are a leading cause of morbidity and mortality globally. Early identification of patients with cirrhosis at high risk of progression to liver-related complications may facilitate timely care and improve outcomes. With risks and misclassification associated with invasive tests, such as liver biopsy, noninvasive imaging modalities for liver fibrosis assessment have gained popularity...

Recent studies have indicated lipid-induced endoplasmic reticulum (ER) stress to be a major contributor to the progression of hepatic steatosis. Exenatide (Exendin-4), a glucagon-like peptide-1 receptor agonist, is known to improve hepatic steatosis with accumulating evidence. In this study, we investigated whether exenatide could alleviate lipid-induced hepatic ER stress through mammal sirtuin1 (SIRT1) and illustrated the detailed mechanisms. Male C57BL/6J mice challenged with a high-fat diet (HFD) were then treated with exenatide or normal saline by intraperitoneal injection for 4 weeks...

PURPOSE: Myricetin, a dietary flavonoid, is effective in the treatment of obesity and insulin resistance by increasing glucose transport and lipogenesis in adipocyte and diminishing systemic inflammation in obesity. However, it has not been revealed yet whether myricetin is associated with brown adipose tissue (BAT) activation that tightly mediates systemic energy metabolism. Therefore, this study assessed whether myricetin activated brown adipose tissue in db/db mouse. METHODS: Myricetin (400 mg/kg) in distilled water was fed daily by oral gavage to leptin receptor-deficient db/db male mice at 4 weeks of age for 14 weeks...

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is a leading cause of liver disease in developed countries. The association of NAFLD with conduction defects is unknown. The aim of our study was to find whether an association exists between conduction defects and NAFLD. METHODS: This is a case-control retrospective study of 700 patients admitted to Orange Park Medical Center, Orange Park, Florida from 2009 to 2015. Patients with a history of alcohol use, congenital heart disease, infiltrative malignancy, and myocarditis were excluded from the study...

Complex traits arise from the interplay between genetic and environmental factors. The actions of these factors usually appear to be additive, and few compelling examples of gene-environment synergy have been documented. Here we show that adiposity significantly amplifies the effect of three sequence variants (encoding PNPLA3 p.I148M, TM6SF2 p.E167K, and GCKR p.P446L) associated with nonalcoholic fatty liver disease (NAFLD). Synergy between adiposity and genotype promoted the full spectrum of NAFLD, from steatosis to hepatic inflammation to cirrhosis...

Dietary arginine (Arg) supplementation has been proposed to have positive effects on the development of liver diseases. In the present study, we investigate if an oral Arg supplementation in diet protects mice fed a fructose, fat and cholesterol enriched Western-style diet (WSD) from the development of non-alcoholic steatohepatitis (NASH). Female C57BL/6J mice were fed a liquid control diet or a liquid WSD ± Arg (2.49 g/kg body weight/day) for 6 weeks. Indices of liver injury, glucose metabolism and intestinal permeability were determined...

The liver in Wilson disease may demonstrate a wide range of damage patterns. Some patients may present almost no detectable microscopic pathology, while others display lesions consistent with fulminant hepatitis or acute liver failure. Most liver biopsy specimens show moderate to severe steatosis, variable degree of portal and/or lobular inflammation, and fibrosis eventually progressing to cirrhosis. Additional findings include liver cell degeneration and ballooning, Mallory hyaline bodies, liver cell necrosis, and glycogenation of periportal hepatocytic nuclei...

Wilson disease is an autosomal-recessive disorder originating from a genetic defect in the copper-transporting ATPase ATP7B that is required for biliary copper secretion and loading of ceruloplasmin with copper. Impaired ATP7B function in Wilson disease results in excessive accumulation of copper in liver, brain, and other tissues. Toxic copper deposits may induce oxidative stress, modify expression of genes, directly inhibit proteins, and impair mitochondrial function, leading to hepatic, neuropsychiatric, renal, musculoskeletal, and other symptoms...

Sodium glucose cotransporter 2 inhibitors are expected to ameliorate the abnormalities associated with metabolic syndrome including non-alcoholic fatty liver disease. In this study, we investigated the effects of the sodium glucose cotransporter 2 inhibitor tofogliflozin on the development of non-alcoholic fatty liver disease-related liver tumorigenesis in C57BL/KsJ-+Leprdb/+Leprdb obese and diabetic mice. The direct effects of tofogliflozin on human liver cancer cell proliferation were also evaluated. Mice were administered diethylnitrosamine-containing water for 2 weeks and were treated with tofogliflozin throughout the experiment...

Nonalcoholic fatty liver disease (NAFLD) is a spectrum of liver disorders ranging from simple hepatic steatosis up to nonalcoholic steatohepatitis (NASH) evolving to cirrhosis and hepatocellular carcinoma (HCC). Liver biopsy is still the gold standard modality for diagnosing and staging NAFLD. The linkage between intestinal microbiota and NAFLD, might suggest a potential role of serum zonulin in NAFLD diagnosis. To appraise the role of circulating zonulin in NAFLD pathogenesis, 56 subjects with proved NAFLD by ultrasonography and liver biopsy, as well as 20 healthy controls were tested...

Lipid droplets are dynamic organelles that store neutral lipids during times of energy excess and serve as an energy reservoir during deprivation. Many prevalent metabolic diseases, such as the metabolic syndrome or obesity, often result in abnormal lipid accumulation in lipid droplets in the liver, also called hepatic steatosis. Obesity-related steatosis, or NAFLD in particular, is a major public health concern worldwide and is frequently associated with insulin resistance and type 2 diabetes mellitus. Here, we review the latest insights into the biology of lipid droplets and their role in maintaining lipid homeostasis in the liver...

Fatty liver can be diet, endocrine, genetic, viral, or drug induced. Independent of cause, hepatic lipid accumulation promotes systemic metabolic dysfunction. By acting as peroxisome proliferator activated receptor (PPAR) ligands, hepatic non-esterified fatty acids upregulate expression of gluconeogenic, beta-oxidative, lipogenic, and ketogenic genes, promoting hyperglycemia, hyperlipidemia, and ketosis. The typical hormonal environment in fatty liver disease consists of hyperinsulinemia, hyperglucagonemia, hypercortisolemia, growth hormone deficiency, and elevated sympathetic tone...

Non-alcoholic fatty liver disease (NAFLD) has become a global health problem. However, there is no approved therapy for NAFLD. Farnesoid X receptor (FXR) is a potential drug target for treatment of NAFLD. In an attempt to screen FXR agonists, we found that cycloastragenol (CAG), a natural occurring compound in Astragali Radix, stimulated FXR transcription activity. In animal studies, we demonstrated that CAG treatment resulted in obvious reduction of high-fat diet induced lipid accumulation in liver accompanied by lowered blood glucose, serum triglyceride levels and hepatic bile acid pool size...

RATIONALE: Hepatic steatosis develops after liver transplant in 30% of adults, and non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in non-transplanted children. However, post-transplant steatosis has been minimally studied in pediatric liver transplant recipients. We explored the prevalence, persistence, and association with chronic liver damage of hepatic steatosis in these children. RESULTS: In this single-center study of pediatric patients transplanted 1988-2015 (n=318), 31% of those with any post-transplant biopsy (n=271) had ≥1 biopsy with steatosis...

Ecotoxicity of glyphosate (GLY) and its metabolite aminomethylphosphonic acid (AMPA) was investigated in guppies, Poecilia reticulata. We tested the effects of these chemicals on the gills and liver of both male and female guppies using qualitative and quantitative histopathological analyses associated with histopathological condition indexes. Both genders showed similar median lethal concentration (LC50 ) at 96 h for GLY (68.78 and 70.87 mg l(-1) ) and AMPA (180 and 164.32 mg l(-1) ). However, the histopathological assessment of both fish organs exposed to sublethal concentrations of GLY (35 mg l(-1) ) and AMPA (82 mg l(-1) ) for 96 h showed a tissue- and gender-specific histopathological response...
