In this paper, we document the face detection competition that we have organized in conjunction with the ISDA 2010 conference. The objective was to compare different face detection engines performance on new unpublished datasets. We believe researchers can benefit from this competition by identifying strong and weak areas in their algorithms relative to(More)
BACKGROUND Postprandial acid reflux is thought to be mediated by the increase in transient lower oesophageal sphincter relaxations (TLOSR) frequency and fall in lower oesophageal sphincter (LOS) pressure seen after ingestion of a meal. Studies in animals and healthy volunteers suggest that cholecystokinin (CCK) may play a role. AIM To study the role of(More)
BACKGROUND Delayed-release mesalazine is traditionally taken as three divided doses. However, it is well-recognized that dosing frequency has a significant impact on compliance and that once daily dosing is preferable. METHODS We measured serum, urinary, faecal and rectal tissue concentrations of 5-aminosalicylic acid and N-acetyl 5-aminosalicylic acid in(More)
AIMS Delayed-release formulations of mesalazine often rely on the gastrointestinal luminal pH profile to deliver 5-aminosalicylic acid (5ASA) to the colon. The aim of this study was to examine the influence of luminal pH on mesalazine release. METHODS We studied the effect of co-administration of omeprazole and lactulose on the steady-state(More)
BACKGROUND The aim of the study was to investigate the therapeutic role of lymphadenectomy (LND) in patients with intrahepatic cholangiocarcinoma. METHODS 826 patients who underwent liver resection were identified using the SEER database from 1988 to 2011. Two groups of patients were defined: 201 (24%) undergoing potentially therapeutic LND (group A, >3(More)
We describe a sensitive high-performance liquid chromatographic method for the determination of 5-aminosalicylic acid and N-acetyl-5-aminosalicylic acid in rectal tissue biopsies. Samples were derivatised using propionic anhydride and proteins were precipitated with methanol. A Supelcosil ABZ column (150x4.6 mm I.D., 5 microm silica particles) was used with(More)
The innervation pattern of the adult donkey testis was investigated by immunohistochemistry and acetylcholinesterase histochemistry. Autonomous nerves reach the testis by three access-routes as funicular, mesorchial and caudal contributions. From these, the funicular contribution accompanying the testicular artery and pampiniform plexus is the strongest and(More)
PURPOSE The objective of this work was to compare the effect of a bradykinin potentiating (BPF) isolated from venom of Egyptian scorpion Androctonus amoreuxi as a natural angiotensin converting enzyme inhibitor (ACEI) with losartan (LOS), a chemical angiotensin receptor blocker (ARB), in the modulation of radiation-induced damage.
