Gastric cancer is a rare condition affecting patients with familial adenomatous polyposis (FAP). The mainstay of treatment is total gastrectomy. Since duodenal cancer is the most common cause of death after total colectomy in FAP, endoscopic surveillance for duodenal cancer is mandatory. Here, we describe the use of an isoperistaltic jejunal loop interposition technique to reconstruct the digestive tract after total gastrectomy in 2 patients with FAP. There were no early or late complications. Both patients are still alive and in good clinical condition. They did not experience weight loss or symptoms of dumping syndrome. Duodenal endoscopic surveillance after this technique was easier than after the classical Roux-en-Y reconstruction. Hence, regular follow-up was possible for both patients.

<P>Nonaqueous lithium-oxygen batteries have a much superior theoretical gravimetric energy density compared to conventional lithium-ion batteries, and thus could render long-range electric vehicles a reality. A molecular-level understanding of the reversible formation of lithium peroxide in these batteries, the properties of major/minor discharge products, and the stability of the nonaqueous electrolytes is required to achieve successful lithium-oxygen batteries. We demonstrate that the major discharge product formed in the lithium-oxygen cell, lithium peroxide, exhibits a magnetic moment. These results are based on dc-magnetization measurements and a lithium-oxygen cell containing an ether-based electrolyte. The results are unexpected because bulk lithium peroxide has a significant band gap. Density functional calculations predict that superoxide-type surface oxygen groups with unpaired electrons exist on stoichiometric lithium peroxide crystalline surfaces and on nanoparticle surfaces; these computational results are consistent with the magnetic measurement of the discharged lithium peroxide product as well as EPR measurements on commercial lithium peroxide. The presence of superoxide-type surface oxygen groups with spin can play a role in the reversible formation and decomposition of lithium peroxide as well as the reversible formation and decomposition of electrolyte molecules.</P>
