abstract  background: pixe (particle induced x-ray emission) is a suitable method for the analysis of biological samples in which heavy trace elements are contained in light matrix elements. it is very important to know which factors or probably elements act as initial seed and lead to growing the sands. the goal of this study was to compare the relative values of fe/k, cu/k and zn/k for gallst...

BACKGROUND Gallstones are a highly prevalent condition; however, the nutritional and lifestyle risk factors of this disease are not well understood. OBJECTIVE We evaluated the association between diet, physical activity, and incident cases of gallstones diagnosed by ultrasound in a population-based, case-control study. DESIGN One hundred patients with newly diagnosed gallstones and 290 rand...

BACKGROUND AND RATIONALE We aimed to provide novel information to better understand the molecular mechanisms underlying gallstones formation and explore the potential protein markers for gallstones progression. The gallbladder tissues were collected from 20 patients with cholesterol gallstone and 10 liver transplant donors from November 2010 to April 2011. The proteomics were compared between g...

BACKGROUND Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) predict severity in various diseases. In this study, we evaluated the value of NLR and PLR as prognostic factors in acute pancreatitis (AP). METHODS Patients with AP were prospectively enrolled from March 2014 to September 2016 at Yonsei University Wonju College of Medicine. NLR and PLR were obtained at adm...

INTRODUCTION Gallstone ileus is a mechanical obstruction caused by the impaction of one or more gallstones within the lumen of any part of the gastrointestinal tract. Although the disorder is a rare cause of small bowel obstruction (1% to 2%), it has been reported to cause up to 25% of cases of non-strangulated small bowel obstruction in patients over 65 years of age. CASE PRESENTATION We rep...

The activity of acyl CoA: cholesterol acyltransferase (ACAT), which catalyzes the esterification of cholesterol, was studied in liver microsomes obtained from cholestyramine-treated gallstone patients (n = 12) and patients with Crohn's disease who had undergone partial ileal resection (n = 11). Gallstone patients (n = 33) and gallstone-free subjects undergoing cholecystectomy because of polyps ...

OBJECTIVE To determine the use of liver function tests (LFTs) as a selection tool for preoperative endoscopic retrograde cholangiopancreatography (ERCP) in patients with mild gallstone pancreatitis. METHODS All patients admitted with mild gallstone pancreatitis with deranged LFTs in King Saud Medical City, Riyadh, Kingdom of Saudi Arabia between January 2006 and February 2013 were studied ret...

BACKGROUND Cholelithiasis is one of the most prevalent gastrointestinal disorders requiring hospitalization.  While different factors influence gallstone formation in patients, these factors are not the same in different societies or in different geographical locations. AIM To evaluate the epidemiology and risk factors associated with gallstone formation in a large population group, the prese...
