Resection of giant gastric GIST with a new generation ultrasonic scalpel device

引用

World Journal of Clinical Cases 2014年第1期2卷 9-11页

作者： Crispin schneider david f Hewin Division of Surgery and Interventional Science University College London Bloomsbury Campus London WC1E 6AU United Kingdom Department of General Surgery Gloucestershire Royal Hospital Gloucester GL1 3NN United Kingdom

Gastrointestinal stroma tumours(GIST) are the most common mesenchymal tumour in the digestive tract and commonly found in the stomach. The patient described in this report presented with collapse and a palpable abdominal mass. He was found to have a large gastric GIST that penetrated through the mesocolon. Resection of the GIST was technically challenging but facilitated by a new generation ultrasonic scalpel device. In resection of gastric cancer the use of ultrasonic scalpels has been shown to reduce operating time, blood loss and length of stay. We feel that in technically challenging cases of gastric GIST the use of an ultrasonic scalpel device may be justified as well.

The Sandfish's Skin:Morphology,Chemistry and Reconstruction

The sandfish is a lizard having the remarkable ability to move in desert sand in a swimming-like fashion. The most outstanding adaptations to this mode of life are the low friction behaviour and the extensive abrasion resistance of the sandfish skin against sand, outperforming even steel. We investigated the topography, the composition and the mechanical properties of sandfish scales. These consist of glycosylated keratins with high amount of sulphur but no hard inorganic material, such as silicates or lime. Remarkably, atomic force microscopy shows an almost complete absence of attractive forces between the scale surface and a silicon tip, suggesting that this is responsible for the unusual tribological properties. The unusual glycosylation of the keratins was found to be absolutely necessary for the described phenomenon. The scales were dissolved and reconstituted on a polymer surface resulting in properties similar to the original scale. Thus, we provide a pathway towards exploitation of the reconstituted scale material for future engineering applications.

Bifidobacterium lactis attenuates onset of inflammation in a murine model of colitis

引用

World Journal of Gastroenterology 2011年第4期17卷 459-469页

作者： david Philippe Laurent favre francis foata Oskar Adolfsson Genevieve Perruisseau-Carrier Karine Vidal Gloria Reuteler Johanna Dayer-schneider Christoph Mueller Stéphanie Blum Department of Nutrition and Health Nestlé Research Centre Department of Pathology University of Bern

AIM: To assess the anti-inflammatory effect of the probiotic Bifidobacterium lactis (B. lactis) in an adoptive transfer model of colitis. METHODS: Donor and recipient mice received either B. lactis or bacterial culture medium as control (deMan Rogosa Sharpe) in drinking water for one week prior to transfer of a mix of naive and regulatory T cells until sacrifice. RESULTS: All recipient mice developed signs of colonic inflammation, but a significant reduction of weight loss was observed in B. lactis-fed recipient mice compared to control mice. Moreover, a trend toward a diminution of mucosal thickness and attenuated epithelial damage was revealed. Colonic expression of pro-inflammatory and T cell markers was significantly reduced in B. lactis-fed recipient mice compared to controls. Concomitantly, forkhead box protein 3, a marker of regulatory T cells, was significantly up-regulated by B. lactis. CONCLUSION: Daily oral administration of B. lactis was able to reduce inflammatory and T cells mediators and to promote regulatory T cells specific markers in a mouse model of colitis.

经过多年的研究、开发和辩论，新一代高技术驱逐舰系列中的第一艘——朱姆沃尔特号即将完工。20年前，美国海军就开始设计这艘当时被称为“21世纪驱逐舰”的舰艇。他们计划组成一个拥有32艘导弹驱逐舰的舰队，在海岸线附近巡航，并以超乎想象的威力对陆上的军事力量进行攻击。但是，2001年，海军取消了这一计划，并重新制定了一个成本较低的计划。
