T he flagship publication of the MTT-S is IEEE Transactions on Microwave Theory and Techniques. As the premier journal in the microwave field, we seek to capture and disseminate knowledge of RF, microwave, guided-wave, and wireless technologies. We provide a service to many of our members who want to publish their contributions, and we provide a service to(More)
Young female mice fed a choline-deficient, ethionine-supplemented (CDE) diet for 24 h develop hemorrhagic pancreatic necrosis with a 5-day mortality rate of approximately 50%. At the end of the diet administration, the in vivo discharge of digestive enzymes is blocked, images of exocytosis and luminal membrane recycling disappear, and zymogen granules(More)
We have hypothesized that the colocalization of digestive zymogens with lysosomal hydrolases, which occurs during the early stages of every experimental pancreatitis model, facilitates activation of those zymogens by lysosomal hydrolases such as cathepsin B and that this activation triggers acute pancreatitis by leading to acinar cell injury. Some, however,(More)
Supramaximal stimulation of the rat pancreas with CCK, or its analog caerulein, triggers acute pancreatitis and a number of pancreatitis-associated acinar cell changes including intracellular activation of digestive enzyme zymogens and acinar cell injury. It is generally believed that some of these various acinar cell responses to supramaximal secretagogue(More)
Severe pancreatitis is frequently associated with acute lung injury (ALI) and the respiratory distress syndrome. The role of granulocyte-macrophage colony-stimulating factor (GM-CSF) in mediating the ALI associated with secretagogue-induced experimental pancreatitis was evaluated with GM-CSF knockout mice (GM-CSF -/-). Pancreatitis was induced by hourly(More)
The complex events by which digestive enzyme zymogens and lysosomal hydrolases are segregated from each other and differentially transported to their respective membrane-bound intracellular organelles in the pancreas have been noted to be disturbed during the early stages of several models of experimental pancreatitis. As a result, lysosomal hydrolases such(More)
Lysed Torpedo synaptosomes or washed synaptosomal membranes were incubated with [32P]NAD+ and subjected to electrophoresis on SDS-polyacrylamide gels. More than eight membrane proteins were ADP-ribosylated. The most intensely labeled proteins were those of Mr = 62,000 and 82,000. Radiolabeling was more intense in synaptosomes than in other subcellular(More)
