iran is a major world producer of walnuts and a hub of walnut exports to other countries. walnut harvesting and cracking is still done manually, which increases price and waste. design and development of an effective harvester and walnut crusher is required to reduce costs and wastage. this study determined the mechanical properties of a test apparatus employing two flat jaws using different tr...

premature rupture of membranes (prom) is one of the most common complications of pregnancy that has a major impact on neonatal outcomes. with respect to racial, nutritional and cultural differences between developed and developing countries, this study was conducted to detect the prevalence of neonatal complications following prom and the role of the duration of rupture of membranes in producin...

Clinical data regarding mucosa-associated lymphoid tissue lymphoma (MALToma) solely involving the duodenum are sparse because of the relative rarity of the disease. A comprehensive literature review revealed only 17 cases reported until 2004, and only a moderate number of cases have been reported since. MALToma can be asymptomatic in its very early stages but frequently produces localized or no...

INTRODUCTION Duodenal obstructions caused by congenital anatomic abnormalities are rare in adults. Several patients in whom the duodenal obstruction was caused by a congenital duodenal diaphragm have been described. The duodenal obstruction in the patient presented herein was caused by a transverse septum, which has not been previously reported. A transverse septum is usually observed in the va...

Functional dyspepsia (FD) is a heterogeneous disorder associated with diverse pathophysiologic mechanisms. Studies have shown duodenal implications in the pathophysiology of FD. Duodenal hypersensitivity to acid, increased duodenal acid exposure, and abnormal responses to duodenal lipids or released cholecystokinin have been observed in patients with FD. Moreover, there is evidence indicating d...

The release of immunoreactive prostaglandin E2 (PGE2) and leukotriene C4 (LTC4) from antral and duodenal mucosal biopsy specimens taken from 20 patients with duodenal ulcer disease was measured by radioimmunoassay before and four weeks after treatment with colloidal bismuth subcitrate. Gastroscopic and histological examination showed complete ulcer healing in 15/18 patients and duodenal histolo...

The common form of duodenal diverticula is due to an out-pouching of the duodenal mucosa. Duodenal diverticula are thought to be acquired and occur at points of weakness on the medial duodenal wall. The diverticulum is usually solitary and is seen in two per cent of upper gastrointestinal series.1 Ninety-six per cent of duodenal diverdcula occur in the second part of the duodenum.2 One such pat...

Diverticula rarely occur within the lumen of the duodenum and are diagnosed in 2-5% of patients. They usually arise near the papilla of Vater and extend distally [1]. Duodenal diverticula are classified into two types: extraluminal or intraluminal. Although the patient with a diverticulum may be asymptomatic, a duodenal diverticulum usually presents with typical or atypical symptoms of peptic u...

Background Uterine rupture in a term pregnancy is an adverse and rare event with serious maternal and fetal consequences. The history of uterine septum resection is considered as a risk factor for uterine rupture. Women with such circumstances are thus recommended to be considered as having a high-risk pregnancy. Accordingly, their prenatal care should be implemented in shorter intervals during...

We present a unique case of duodeno-duodenal intussusception from a duodenal bulb ulcer. A 38-year-old man presented with nausea, vomiting, and abdominal pain. Computed tomography showed duodenal intussusception. Esophagogastroduodenoscopy (EGD) showed a linear gastric ulcer and a duodenal bulb ulcer with an overlying blood clot. Helicobacter pylori status was positive. Intussusception resolved...
