However,the interest of research is increasing. Fat accumulation,associated with obesity and the metabolic syndrome(Met S),has been defined as "fatty infiltration" or "nonalcoholic fatty pancreas disease"(NAFPD). The term "fatty replacement" describes a distinct phenomenon characterized by death of acinar cells and replacement by adipose tissue. Risk factors for developing NAFPD include obesity,increasing age,male sex,hypertension,dyslipidemia,alcohol and hyperferritinemia. Increasing evidence support the role of pancreatic fat in the development of type 2 diabetes mellitus,Met S,atherosclerosis,severe acute pancreatitis and even pancreatic cancer. Evidence exists that fatty pancreas could be used as the initial indicator of "ectopic fat deposition",which is a key element of nonalcoholic fatty liver disease and/or Met S. Moreover,in patients with fatty pancreas,pancreaticoduodenectomy is associated with an increased risk of intraoperative blood loss and post-operative pancreatic fistula.展开更多

Total viral DNA and RNA was isolated and quantified for establishing the correlation with metabolic measures and composition of gut bacterial communities.RESULTS: In this report, we found that obese mice feces have higher viral contents in terms of total viral DNA and RNA(P < 0.001). Interestingly, these increased viral DNA and RNA content were tightly correlated with metabolic measures, i.e., body weight, fat mass and fasting blood glucose. Total viral content were positively correlated with firmicutes(R^2 > 0.6), whilst negatively correlated with bacteroidetes and bifidobacteria. CONCLUSION: This study suggests the strong correlation of increased viral population into the gut of obese mice and opens new avenues to explore the role of gut virome in pathophysiology of obesity.展开更多

The present study aimed to test the effect of the supplementation with red palm oil（RPO）, which is a natural oil obtained from oil palm fruit（Elaeis guineensis） rich in natural fat-soluble tocopherols, tocotrienols and carotenoids, on lipid peroxidation and endotoxemia with plasma endotoxin-inactivating capacity, proinflammatory cytokines profile, and monocyte tissue factor in patients with chronic liver disease. METHODS： The study group consisted of sixty patients（34 males and 26 females; mean age 62 years, range 54-75） with Child A/B, genotype 1 HCV-related cirrhosis without a history of ethanol consumption, randomly enrolled into an 8-week oral daily treatment with either vitamin E or RPO. All patients had undergone an upper gastrointestinal endoscopy 8 months before, and 13 out of them showed esophageal varices.RESULTS： Both treatments significantly decreased erythrocyte malondialdehyde and urinary isoprostane output, only RPO significantly affected macrophage-colony stimulating factor and monocyte tissue factor. Liver ultrasound imaging did not show any change. CONCLUSIONS： RPO beneficially modulates oxidative stress and, not least, downregulates macrophage/monocyte inflammatory parameters. RPO can be safely advised as a valuable nutritional implementation tool in the management of chronic liver diseases.展开更多
