Mit mobilen Computern lassen sich Geschäftsprozesse unterstützen und Aufgaben auf Mitarbeiter vor Ort übertragen. Neben den offensichtlichen Nutzen bergen solche Lösungen auch Risiken: Vor allem können Bezugsobjekte verwechselt werden – Fehlbedienungen oder -steuerungen sind die Folge. Der Artikel schlägt vor, diesen Risiken mit ortsabhängigen Zugriffskontrollen zu begegnen und zeigt erste Ansä...

The present study was aimed at studying the effects of inclusion of pomegranate seed extract to fat-containing diets on nutrients digestibility, intestinal microflora and performance of broilers. A total of 320 one-day-old broiler chicks (Ross 308) were selected in a 2 × 2 × 2 factorial experiment in a completely randomized design with 4 replicates o...

A hypothesis was tested in this study that antagonists of adrenergic and cholinergic receptors affect sodium and chloride ion transport in the rabbit caecum. A modified Ussing chamber was used in the experiment. It was demonstrated that isolated caecum responded to a mechanical stimulus, which consisted in gentle rinsing of the mucous surface, with changes in transepithelial electrical potentia...

Effect of capsaicin, a stimulator of C-fibres, on ion transport in the caecum of rabbits was studied using electrophysiological methods, designed to evaluate ionic currents occurring in epithelial tissues. The experiments consisted in measuring transepithelial electrical potential difference (dPD) of an isolated fragment of rabbit's caecum, placed in a Ussing apparatus. The ion transport was mo...

In previous experiments, i.p. injection of the 5 nitronaphthofuran derivative 7-methoxy-2-nitronaphtho[2,1-b]furan (R7000) to lacI transgenic Big Blue mice led to an increase in the mutant frequency (MF), especially in the caecum and the small intestine. In the present work, the in vivo genotoxicity of R7000 in these two target organs was further investigated. Big Blue mice were treated with a ...

Appendicitis can rarely occur in association with carcinoma of the caecum, particularly in elderly patients. We report a case of acute appendicitis provoked by an adenocarcinoma of the caecum which obstructs the lumen of the appendix in a 58-year-old man. The patient underwent an ileocaecal resection with lymph node dissection. The difficulties of identifying a small tumor at laparotomy and the...
