Four cases of Dieulafoy's vascular malformation of the caecum are reported. Three were associated with massive large bowel haemorrhage, one of which was fatal. The remaining case had a calibre persistent submucosal artery within the caecum that was found incidentally in a resection specimen. This vascular malformation should be considered when dealing with specimens resected for massive lower g...

Salmonella enterica Enteritidis (S. Enteritidis) and Salmonella enterica Pullorum (S. pullorum) are regarded as a threat to poultry production. This study's aim is to characterize the expression profiles in response to three different challenges and to identify infection-related genes in the chicken spleen and caecum. Groups of the Chinese chicken breed Langshan were challenged with either S. E...

A duplication cyst of the caecum is a very rare congenital malformation, representing 0.4% of all gastrointestinal duplications. We present a case of cystic duplication of the caecum in a 12-year-old child who presented with a right iliac fossa mass and peritonitis. An ischaemic, perforated caecal duplication cyst was found on emergency laparotomy, mandating a right hemicolectomy.

A patient who presented with acute intestinal obstruction had a right hemicolectomy for a caecal tumour. The histopathology report confirmed metastatic carcinoma in the caecum from the cervical carcinoma. Caecum is a very rare site of metastasis from cervical carcinoma. From our literature review, there have been no such cases reported.

Gastric emptying half-time and mouth to caecum transit time of a solid meal were measured in eight normal volunteers, once during a period of psychological stress and again during a period of relative calm. No consistent or significant effect on gastric emptying was observed, but mouth to caecum transit times were faster in all subjects and this difference was highly significant (p<0.01).

We have developed a pig caecal cannulation model that allows us to evaluate the effects in vivo of feed withdrawal on (1) the caecal environment, including pH and volatile fatty acid (VFA) concentration, and (2) the growth of foodborne pathogens in the caecum. In vitro studies evaluated growth of Yersinia enterocolitica and Salmonella typhimurium at five concentrations of VFA at four pH levels....

The effects of purified scorpion toxin (Tityustoxin or TsTX) were investigated on the isolated guinea-pig and rat ileum, rat spleen strip and hen rectal caecum. The contraction of the ileum was due only in part to the release of acetylcholine, whereas the contraction of the spleen strip and the relaxation of the rectal caecum were due to the release of catecholamines.

Besucher kulturhistorischer Sehenswürdigkeiten möchten sich meist umfassend aber auch speziell zu bestimmten Details eines Denkmals informieren. Im Fall des jüdischen Friedhofs „Heiliger Sand“ in Worms werden Gästeführungen angeboten und eine Schautafel informiert am Eingang des Friedhofs. Dieses Angebot zeitund ortsunabhängig zu ergänzen und das individuelle Besuchererlebnis von Kulturtouriste...

To remain competitive many businesses in the 1990’s have undertaken business process reengineering projects reorganising one or more parts of their operations. This paper results from a case study of the enterprise-wide review of Mobil Oil Australia Limited to increase profitability and change the culture of the organisation. A radical (to the Oil Industry) business unit organisation structure ...

Anhand von Robotik-Projekten wird ein in unserer Unterrichtspraxis inzwischen bewährter Weg aufgezeigt, den Lernenden ein durchgehend attraktives (be)greifbares Lernobjekt und den Lehrenden eine nach oben offene Aufgabenstellung zu offerieren. Beginnend bei einer simplen Transistorschaltung eines klassischen Linienfolgers bis hin zu einem programmgesteuerten autonomen RoboterModell werden versc...
