Introduction: This study was done to determine the site of obstruction in lacrimal drainage system in Asian patients suffering from epiphora and to determine the transit time taken for the tracer material to reach the lacrimal sac and the nasal cavity. Methods:Dacryoscintigraphy was performed using radionuclide technetium-99m pertechnetate (99m...
Chyloperitoneum is rare condition that can occur in response to various pathologic process. The authors described a newborn baby who had chyloperitoneum after primary surgical repair of esophageal atresia with tracheoesophageal fistula (Gross type C). This probably resulted from iatrogenic damage of the thoracic duct during ligation of azygous vein resulting in leaking lacteal within the intest...
Intestinal lipoproteins, especially triglyceride-rich chylomicrons, are a major driver of metabolism, inflammation, and cardiovascular diseases. However, isolating intestinal lipoproteins is very difficult in vivo because they first secreted from the small intestine into mesenteric lymphatics. Chylomicron-containing lymph then empties subclavian vein thoracic duct to deliver components meal hea...
Unlimited in vitro expansion of adult bi-potent pancreas progenitors through the Lgr5/R-spondin axis
Lgr5 marks adult stem cells in multiple adult organs and is a receptor for the Wnt-agonistic R-spondins (RSPOs). Intestinal, stomach and liver Lgr5(+) stem cells grow in 3D cultures to form ever-expanding organoids, which resemble the tissues of origin. Wnt signalling is inactive and Lgr5 is not expressed under physiological conditions in the adult pancreas. However, we now report that the Wnt ...
The purpose of this study is to describe the histological, histochemical and ultrastructural features of pancreas of the grass carp (Ctenopharyngodon idella), one of the common herbivorous freshwater fish of Egypt. The pancreas is divided into exocrine and endocrine portions. Exocrine pancreatic tissues consists of scattered serous acini, and is observed in two forms: 1) disseminated in the spl...
INTRODUCTION AND OBJECTIVES Transcatheter closure of patent ductus arteriosus is a well-established procedure. The aim of this study was to assess the initial and mid-term results of the treatment of PDA with the Amplatzer duct occluder. PATIENTS AND METHODS From October 1999 to December 2001, 30 children underwent transcatheter closure of persistent ductus arteriosus at a mean SD age of 5 4....
Received 11 March 2002. Accepted for publication 28 May 2002. Introduction and objectives. Transcatheter closure of patent ductus arteriosus is a well-established procedure. The aim of this study was to assess the initial and midterm results of the treatment of PDA with the Amplatzer duct occluder. Patients and methods. From October 1999 to December 2001, 30 children underwent transcatheter clo...
Patent ductus arteriosus (PDA) constitutes 6 to 11% of all congenital heart defects. While surgical ligation and video-assisted, thoracoscopic interruption of PDA are still available, transcatheter occlusion of PDAs has recently assumed a major role in closure of PDA. A large number of devices have been designed and tested both in animal models and human subjects, but only few devices (free and...
A 64-year-old man underwent MRCP for further examination of gallbladder stones and IPMN of branch-type (IPMN-Br) was pointed out. Yearly MRCP had revealed the gradual increase of the cystic components, marked dilation of the main pancreatic duct (MPD), and filling defects in the MPD. After follow-up for three years, he underwent pancreatoduodenectomy. Histologically, the dilated MPD and connect...
