The aim of this work was to evaluate and compare the effects of a low calorie diet (1026 kcal), simvastatin and ursodeoxycholic acid administration on biliary lipid secretion and cholic acid kinetics in dieting obese subjects. We studied 6 obese subjects before and after four weeks of a hypocaloric
OBJECTIVE
We have recently established a novel swine model for studies of atherosclerosis using MicrominipigsTM (µMPs) fed a high-fat/high-cholesterol diet (HcD). Using this swine model, we re-evaluated the effects of dietary cholic acid (CA) on serum lipid profile, atherosclerosis and hepatic
Recent studies have shown colestimide, a bile acid-binding resin, to also exert a glucose-lowering effect via amelioration of insulin resistance. To evaluate the effects of colestimide on glucose metabolism and to elucidate the underlying mechanism, we conducted a 6-month, open-label pilot study on
Cholesterol gallstones occur three times more frequently in morbidly obese subjects than in normal controls. The present study tests the hypothesis that obese subjects develop gallstones because of relative and absolute excess cholesterol excretion in bile. The steady-state kinetics of biliary lipid
Chenodeoxycholic acid (CDCA), in contrast to cholic acid (CA), reduces cholesterol saturation of bile. The mechanisms for these differences were the object of this study. Investigations were carried out in nine white men; three nonobese subjects and one obese subject were fed a weight-maintenance

We tested the hypothesis that fecal microbiota transplantation (FMT) could regulate the biotransformation of bile acids, such as deoxycholic acid (DCA) and cholic acid (CA), which in turn regulate the biosynthesis of serotonin in the gut and relieve gastrointestinal dysmotility in
Bile cholesterol, phospholipids, total bile acids, individual bile acids, and fatty acid compositions of bile neutral lipids and phospholipids were analyzed before, at one month and at six months following jejunoileal bypass surgery in a series of morbidly obese patients. Preoperative mole
1. The present study was undertaken to determine the influence of obesity on bile acid kinetics and cholesterol balance in man. 2. Fourteen obese and normolipidaemic patients (160 +/- 6% of ideal body weight, mean +/- SEM) were studied under standardized dietary conditions. Bile acid kinetics, were
Obese subjects are prone to supersaturated bile, which is maintained or increased during weight loss. In this report, two related studies were carried out on obese subjects to investigate effects of bile acid feeding on biliary lipid metabolism before and during weight reduction. In one study,
The relationship between obesity and cholesterol cholelithiasis is not well understood at physiologic or genetic levels. To clarify whether obesity per se leads to increased prevalence of cholelithiasis, we examined cholesterol gallstone susceptibility in three polygenic (KK/H1J, NON/LtJ, NOD/LtJ)
The aim of this study was to elucidate mechanisms whereby bile acids exert beneficial metabolic effects, using the Cyp8b1-/- mouse as model. These mice are unable to synthesize cholic acid, resulting in increased synthesis of chenodeoxycholic acid and enlarged bile acid pool.
The rising prevalence of morbid obesity is increasing the demand for bariatric surgery. The benefits observed after bariatric surgery seems to be not fully explained by surgery-induced weight loss or traditional cardiovascular risk factors regression or improvement. Some evidences To assess the influence of Roux-en-Y gastric by-pass (RYGB) on fecal bile acid (BA) profile and its relationship with postoperative remission of type 2 diabetes (T2D).Fecal samples were collected 3 and 12 months after RYGB from diabetic obese women who were Bile acid metabolism and duodenal bacterial flora were studied in 12 obese patients before and 1-2 months after jejunoileal bypass operation, either including 37.5 cm jejunum and 12.5 cm ileum (Type I) or 12.5 cm jejunum and 37.5 cm ileum (Type III). The cholic acid pool size was unchanged after
OBJECTIVE
Tsumura-Suzuki obese diabetic (TSOD) is a good model of metabolic syndrome showing typical lesions found in nonalcoholic fatty liver disease and nonalcoholic steatohepatitis, and develops spontaneous hepatic tumors with a high frequency. Majority of the developing tumors overexpress
