A middle-aged man with no symptom or history visited our hospital due to duodenal abnormality and fecal occult blood detected by health screening. Upper gastrointestinal endoscopy showed marked enlargement of the papilla of Vater surrounded by nodules, and biopsy disclosed non-caseating granuloma. Colonoscopy yielded findings suggestive of intestinal tuberculosis such as annular ulcers. Examina...

rabbitfish is economically valuable teleost species which lives in shallow coastalwaters. two species of rabbit fish have been recognized in southern sea of iran (persiangulf) as namely siganus sutor and siganus javus. in the current study, in order toinvestigate the histology of the annular ligament of the s. javus’ eye, the prepared sectionsof the eyes of twelve healthy specimens were studied...

A Study of Annular Slurry Jet for Abrasive Waterjet Cutting

abstract annular pancreas (ap) is a rare congenital malformation resulting from failure of pancreas ventral anlage rotation with the duodenum. this leads to a ring of pancreatic tissue that envelops the duodenum. clinical manifestations of ap most commonly develop in infancy or early childhood but can present at any age. the diagnosis of ap, usually suggested by an upper gi series or abdominal ...

Granuloma annulare is a benign, relatively common dermatosis of childhood and young adults. Lesions typically occur on the extremities. Localized facial and periocular involvement is rare. We describe a 25- year-old woman with asymptomatic skin-color, firm, and papular lesions on both periocular areas since 6 months ago. Histological examination revealed palisading necrobiotic granuloma, charac...

annular pancreas is a rare congenital condition of the pancreas where the pancreatic tissue either partially or completely covers the duodenum by forming a ring. endoscopic ultrasound is rarely considered as the first diagnosis tool for annular pancreas. we here present a 48 years old man who was primarily provisionally diagnosed with pancreatic mass and was planned for pancreatoduodenectomy. b...

some lesions in the oral cavity and mostly on gingiva have predominant predilection towards females, and mostly occur in the first four decades of life when changes in sex hormone levels in blood are obvious. the present study aimed to investigate the presence and distribution of estrogen and progesterone receptors in peripheral giant cell granuloma (pgcg), pyogenic granuloma (pg) and periphera...

The annular foam breaker is one which uses the vacuum and shear force generated by the Coanda effect to break foam. The pressure distribution directly affects its performance. So an investigation on the flow characteristics inside the annular foam breaker is important to optimize its structure. In this paper, the computational fluid dynamics (CFD) code, FLUENT, is employed to simulate the flow ...
