1Sporadic versus hereditary gastrinomas of the duodenum and pancreas: Distinct clinico-pathological and epidemiological features显示文摘Gastrinomas are defined as gastrin secreting tumors that are associated with Zollinger-Ellison syndrome (ZES). ZES is characterized by elevated fasting gastrin serum levels, positive secretin stimulation test and clinical symptoms such as recurrent peptic ulcer disease, gastroesophageal re?ux disease and occasional diarrhea. Genetically, nonhereditary (sporadic) gastrinomas are distinguished from hereditary gastrinomas, which are associated with multiple endocrine neoplasia type 1 (MEN1) syndrome. In general, duodenal gastrinomas are small and solitary if they are sporadic and multiple as well as hereditary. The sporadic gastrinomas occur in the duodenum or in the pancreas while the hereditary gastrinomas almost all occur in the duodenum. Our series of 77 sporadic duodenal neuroendocrine tumors (NETs) includes 18 patients (23.4%) with gastrinomas and ZES. Of 535 sporadic NETs in the pancreas collected from the NET archives of the departments of pathology in Zürich, Switzerland, and Kiel, Germany, 24 patients (4.5%) suffered from sporadic pancreatic gastrinomas and ZES. These NETs have to be distinguished fromtumors with immunohistochemical positivity for gastrin but without evidence of ZES. An additional 19 patients suffered from MEN1 and ZES. These patients showed exclusively duodenal gastrinomas, but not pancreatic gastrinomas. The prognosis of sporadic and MEN1- associated duodenal gastrinomas is better than that of pancreatic gastrinomas, since they progress slowly to liver metastasis. In summary, sporadic and MEN1- associated gastrinomas in the duodenum and pancreas show different clinico-pathological and genetic features. The incidence of sporadic duodenal gastrin-producing tumors is increasing, possibly due to optimized diagnostic procedures. In contrast, pancreatic MEN1- associated gastrinomas seem to be extremely rare. A considerable subset of tumors with immunohistochemical expression of gastrin but without evidence of ZES should be designated as functionally inactive NETs expressing gastrin, but not as gastrinomas.Martin Anlauf Nele Garbrecht Tobias Henopp Anja Schmitt Regina Schlenger Andreas Raffel Markus Krausch Oliver Gimm Claus F Eisenberger Wolfram T Knoefel Henning Dralle Paul Komminoth Philipp U Heitz Aurel Perren Günter Klppel 2006World Journal of Gastroenterology2006,12,34:7

19Challenges in the Technology Development for Additive Manufacturing in Space显示文摘Instead of foreseeing and preparing for all possible scenarios of machine failures,accidents,and other challenges arising in space missions,it appears logical to take advantage of the flexibility of additive manufacturing for“in-space manufacturing”(ISM).Manned missions into space rely on complicated equipment,and their safe operation is a great challenge.Bearing in mind the absolute distance for manned missions to the Moon and Mars,the supply of spare parts for the repair and replacement of lost equipment via shipment from Earth would require too much time.With the high flexibility in design and the ability to manufacture ready-to-use components directly from a computer-aided model,additive manufacturing technologies appear to be extremely attractive in this context.Moreover,appropriate technologies are required for the manufacture of building habitats for extended stays of astronauts on the Moon and Mars,as well as material/feedstock.The capacities for sending equipment and material into space are not only very limited and costly,but also raise concerns regarding environmental issues on Earth.Accordingly,not all materials can be sent from Earth,and strategies for the use of in-situ resources,i.e.,in-situ resource utilization(ISRU),are being envisioned.For the manufacturing of both complex parts and equipment,as well as for large infrastructure,appropriate technologies for material processing in space need to be developed.Andrea Zocca Janka Wilbig Anja Waske Jens Günster Martinus Putra Widjaja Christian Neumann Mélanie Clozel Andreas Meyer Jifeng Ding Zuoxin Zhou Xiaoyong Tian 2022Chinese Journal of Mechanical Engineering(Additive Manufacturing Frontiers)2022,1,1:1
