arteritis due to strongylus vulgaris is a well-known cause of colic in horses and donkeys. the current report describes a fatal incidence of arterial obstruction in cranial mesenteric artery caused by s. vulgaris infection in an adult donkey in which anthelmintic treatment was not regularly administered. necropsy findings of the abdominal cavity revealed a complete cranial mesenteric arterial o...

Vertical silos are large cylinders used for material storage in agriculture and mineral industries. One of the silo problems is its obstruction due to dome and dense packing. Depend on the material properties and silo dimensions several techniques are used to solve this problem. In the present work, possibility of obstruction solution of a laboratory silo by ball impact is investigated. Test ma...

The patient is a 12 year-old girl who has been suffering from episodes of in testinal obstruction since she was 6 years old, leading to severe malnutrition, malabsorption and growth retardation.  Repeated radiological examinations revealed esophageal achalasia, gastric distention, marked small intestinal and mild colonic dilatation. Transmural biopsies from small and large bowels showed normal ...

Ejaculatory duct obstruction (EDO) underlies 1-5% of male infertility, although the diagnosis of EDO can be complex, treatment is well established and can be very effective. Part of reason that this condition probably is underdiagnosed, is because of its rarity, subtle presentation and the concomitantly low index of suspicion held by physicians. The causes of EDO are divided into congenital and...

idiopathic retroperitoneal fibrosis is a rare disorder of an unknown etiology characterized by an inflammatory proliferative fibrosing process that may involve the ureters in 80-100% of cases. â the present study was carried on a 38 years old man who was admitted to imam khomeini hospital with severe abdominal pain and renal failure. abdominal mri showed encasement of abdominal aorta and bilate...

the aim of this paper is to study the $(alpha‎, ‎gamma)$-prolongation of central extensions‎. ‎we obtain the obstruction theory for $(alpha‎, ‎gamma)$-prolongations and classify $(alpha‎, ‎gamma)$-prolongations thanks to low-dimensional cohomology groups of groups‎.
