Introduction: Adherence to the design values and ventilation standards (VS) after installing and also maintaining continuous work of ventilation system with maximum performance throughout its life are amongst the reasons of ventilation systems monitoring. Therefore, the aim of this study was to evaluate performance of local exhaust ventilation system for control of dust by measuring the operati...

The mechanisms linking acinar cell apoptosis and ductal epithelial proliferation remain unknown. To determine the relationship between these events, pancreatic duct ligation (PDL) was performed on p53(+/+) and p53(-/-) mice. In mice bearing a wild-type p53 allele, PDL resulted in upregulation of p53 protein in both acinar cells and proliferating duct-like epithelium. In contrast, upregulation o...

The aim of this study was to examine whether the type of bilioenterostomy enhances biliary carcinogenesis in the hamster model. Syrian hamsters were divided into the following groups; simple laparotomy (control group), cholecystoduodenostomy with dissection of the extrahepatic bile duct on the distal end of the common duct (CDDB group) and cholecystoileostomy with dissection of the extrahepatic...

Since the height of sea detection radar antenna and ship targets is relatively low, it generally believed that its over-the-horizon mainly caused by evaporation duct at sea. To fully understand influence atmospheric ducts on detection, a shore-based navigation was used to carry out experiments; radiosondes were measure profile monitoring equipment duct. Based experimental data model simulation,...

Pancreaticojejunostomy is the key procedure of pancreaticoduodenectomy. Our study introduced a new pancreaticojejunal (PJ) anastomosis named "papillary-like main pancreatic duct invaginated" pancreaticojejunostomy. Nighty-two patients underwent pancreaticojejunostomy with either conventional duct-to-mucosa pancreaticojejunostomy or the new "papillary-like main pancreatic duct invaginated" techn...

Inside air ventilation ducts of the confined space such as subway stations become contaminated by various contaminants and particular matters after long time operation. The accumulated various pollutants at inner duct surface easily transport and cause secondary air contamination and injure subway passengers’ respiratory system and health. In fact, only periodic duct cleaning works can improve ...

Previous studies have suggested a relationship between bile duct stones and periampullary duodenal diverticula. The aim of the present study was to examine this association in more detail, including step-wise logistic regression to identify independent predictors for the presence of diverticula. Clinical, endoscopic and radiological data were analysed from 794 consecutive subjects with bile duc...

A 57-year-old man presented with a 16-month history of right parotid swelling since undergoing a transoral sialolithotomy of the parotid duct. An ultrasound and a computed tomography scan showed a 6 cm-long dilated parotid duct without evidence of sialolithiasis or tumor mass. The complete Stensen's duct stenosis that was found was managed by a surgeon-performed ultrasound-guided transfacial ne...

In addition to imaging the lymphatics and detecting various types of lymphatic leakage, lymphangiography is a therapeutic option for patients with chylothorax, chylous ascites, and lymphatic fistula. Percutaneous thoracic duct embolization, transabdominal catheterization of the cisterna chyli or thoracic duct, and subsequent embolization of the thoracic duct is an alternative to surgical ligati...
