Stellenwert der Rektoskopie und Koloskopie f�r den Internisten

2003

The endoscopic examination of the large intestine can be considered today a routine examination in internal medicine. Since the introduction of flexible videoendoscopy, evaluating diseases in the distal colon using rectoscopy has become less important. Anoproctoscopy is an obligatory component for a complete colon diagnostic after a flexible ileo-colonoscopy has been performed. Colonoscopy has improved significantly the diagnosis and therapy of diseases in the large intestine since it has been introduced more than 30 years ago. By introducing modern videocolonoscopy in addition to other instruments, there is today a broad spectrum of diagnostic and therapeutic indications available. Specifi…

Adverse Effects of Nonsteroidal Anti-Inflammatory Drugs on the Small and Large Bowel

1999

Nonsteroidal anti-inflammatory drugs (NSAID) account for a large part of prescriptions and self-administered medication worldwide. The adverse effects on the upper gastrointestinal tract are well documented. However, in an increasing number of publications adverse effects in the small and large intestine distal to the duodenum are being reported. This paper provides an updated review of current as well as earlier literature on the pathogenesis of such adverse effects and the potential damage to the small and large bowel caused by NSAID. In addition, suggestions for an appropriate diagnostic workup of NSAID damage are discussed.

Endovascular management of a large aneurysm of the superior vena cava involving internal thoracic vein with remodeling technique

2016

International audience; We report a case describing endovascular treatment of a large aneurysm of the superior vena cava involving internal thoracic vein. The goal of this case report is to highlight the contributing role of embolization with remodeling technique in such an exceptional condition.

Imaging of VSOP labeled stem cells in agarose phantoms with susceptibility weighted and T2* weighted MR Imaging at 3T: determination of the detection…

2013

Objectives This study aimed to evaluate the detectability of stem cells labeled with very small iron oxide particles (VSOP) at 3T with susceptibility weighted (SWI) and T2* weighted imaging as a methodological basis for subsequent examinations in a large animal stroke model (sheep). Materials and Methods We examined ovine mesenchymal stem cells labeled with VSOP in agarose layer phantoms. The experiments were performed in 2 different groups, with quantities of 0–100,000 labeled cells per layer. 15 different SWI- and T2*-weighted sequences and 3 RF coils were used. All measurements were carried out on a clinical 3T MRI. Images of Group A were analyzed by four radiologists blinded for the num…

Multi-resolution anisotropy studies of ultrahigh-energy cosmic rays detected at the Pierre Auger Observatory

2017

We report a multi-resolution search for anisotropies in the arrival directions of cosmic rays detected at the Pierre Auger Observatory with local zenith angles up to $80^\circ$ and energies in excess of 4 EeV ($4 \times 10^{18}$ eV). This search is conducted by measuring the angular power spectrum and performing a needlet wavelet analysis in two independent energy ranges. Both analyses are complementary since the angular power spectrum achieves a better performance in identifying large-scale patterns while the needlet wavelet analysis, considering the parameters used in this work, presents a higher efficiency in detecting smaller-scale anisotropies, potentially providing directional informa…

Mechanical activity of small and large intestine in normal and mdx mice: a comparative analysis.

1999

The aim of this study was to compare the motor pattern (recorded as changes in intraluminal pressure) of isolated duodenum and proximal colon between dystrophic mdx and normal mice. When duodenal recordings from control preparations were compared with mdx mice there was no significant difference in the spontaneous motor pattern, responses to electrical nerve stimulation or sensitivity to pharmacological agents. Colonic segments from mdx mice showed a more complex motor pattern, consisting of contractions with amplitude and frequency similar to those of controls and by additional contractions with lower amplitude and higher frequency. Moreover, 70% of the colonic preparations from mdx mice d…

Evaluation of efficacy and biocompatibility of a new absorbable synthetic substitute as a dural onlay graft in a large animal model.

2016

Numerous dura substitutes are commercially available, but no absorbable synthetic dura repair product has been used for both onlay and suture applications.The safety and effectiveness of a new absorbable synthetic substitute composed of Poly-L-lactide microfibers as onlay dural graft were evaluated.Physical properties and performance of the microfibrous synthetic dural substitute implanted as an onlay or suturable grafts were compared with these commercial products, including CODMAN ETHISORB™ Dura Patch and DuraGen™ Dural Graft Matrix, in a canine duraplasty model. The cerebrospinal fluid (CSF) leakage, macroscopic and microscopic observation at 30 and 90 days after implantation were invest…

Saturation and forward jets in proton-lead collisions at the LHC

2019

We investigate the forward-jet energy spectrum within the Color Glass Condensate framework at 5 TeV center-of-mass energy. In particular, we focus on the kinematic range covered by the CMS-CASTOR calorimeter. We show that our saturation-model calculations are compatible with the CASTOR measurements and that to optimally reproduce the data, effects of multi-parton interactions need to be included. We predict a significant nuclear suppression - reaching down to 50% at the lowest considered jet energies $E_{\rm jet} \sim 500 \, {\rm GeV}$.

Stationary sets and asymptotic behavior of the mean curvature flow with forcing in the plane

2020

We consider the flat flow solutions of the mean curvature equation with a forcing term in the plane. We prove that for every constant forcing term the stationary sets are given by a finite union of disks with equal radii and disjoint closures. On the other hand for every bounded forcing term tangent disks are never stationary. Finally in the case of an asymptotically constant forcing term we show that the only possible long time limit sets are given by disjoint unions of disks with equal radii and possibly tangent. peerReviewed
