Ob/ob mice, a model for nonalcoholic fatty liver disease (NAFLD), develop intestinal bacterial overgrowth and overexpress tumor necrosis factor alpha (TNF-alpha). In animal models for alcoholic fatty liver disease (AFLD), decontaminating the intestine or inhibiting TNF-alpha improves AFLD. Because AFLD and NAFLD may have a similar pathogenesis, treatment(More)
CONTEXT Factors associated with the high prevalence of vitamin D deficiency in China are not well described, especially among Chinese adolescents. OBJECTIVES The aim of the study was to examine important environmental or sociodemographic factors influencing 25-hydroxyvitamin D [25(OH)D] levels and estimate its heritability. DESIGN A sample of 226 male(More)
BACKGROUND Higher fat mass may be an independent risk factor for osteoporosis and osteoporotic fractures. OBJECTIVE We aimed to determine the independent contribution of fat mass to osteoporosis and to estimate the risk of osteoporotic fractures in relation to body weight, lean mass, and other confounders. DESIGN This was a community-based,(More)
Cyclin D1 encodes the regulatory subunit of a holoenzyme that phosphorylates and inactivates the retinoblastoma protein and promotes progression through the G1-S phase of the cell cycle. Amplification or overexpression of cyclin D1 plays pivotal roles in the development of a subset of human cancers including parathyroid adenoma, breast cancer, colon cancer,(More)
BACKGROUND/AIMS Dietary factors and intestinal bacteria play an important role in the rapidly increasing incidence of obesity and its associated conditions, such as steatosis and insulin resistance. In the current study, we evaluated the effect of probiotics, and their mechanisms on diet-induced obesity, steatosis and insulin resistance. METHODS Wild-type(More)
Recovery from liver damage might be enhanced by encouraging repopulation of the liver by endogenous hepatic progenitor cells. Oval cells are resident hepatic stem cells that promote liver regeneration and repair. Little is known about the mediators that regulate the accumulation of these cells in the liver. Parasympathetic nervous system inhibition reduces(More)
p21(CIP1/WAF1) is a downstream effector of tumor suppressors and functions as a cyclin-dependent kinase inhibitor to block cellular proliferation. Breast tumors may derive from self-renewing tumor-initiating cells (BT-ICs), which contribute to tumor progression, recurrence, and therapy resistance. The role of p21(CIP1) in regulating features of tumor stem(More)
UNLABELLED Cholangiocarcinoma (CCA) presents significant diagnostic challenges, resulting in late patient diagnosis and poor survival rates. Primary sclerosing cholangitis (PSC) patients pose a particularly difficult clinical dilemma because they harbor chronic biliary strictures that are difficult to distinguish from CCA. MicroRNAs (miRs) have recently(More)
The increasing prevalence of metabolic syndrome (MS) poses a serious public-health problem worldwide. Effective prevention and intervention require improved understanding of the factors that contribute to MS. We analyzed data on a large twin cohort to estimate genetic and environmental contributions to MS and to major MS components and their(More)
BACKGROUND AND AIM SpyGlass® cholangiopancreatoscopy system has shown early success in aiding diagnosis and management of pancreaticobiliary diseases. We aimed to assess the technical success, clinical success, diagnostic yield, therapeutic yield, and safety of the SpyGlass® system at a single institution. METHODS A retrospective, single-center review of(More)
