Methods. We produced alginate microcapsules containing baby hamster kidney (BHK) cells overexpressing IDUA and implanted these capsules in the peritoneum of MPS I mice. Results. An increase in serum and tissue IDUA

activity was observed at early time-points, as well as a reduction in GAG storage; however, correction in the long term was only partially achieved, with a drop in the IDUA activity being observed a few weeks after the implant. Analysis of the capsules obtained from the peritoneum revealed inflammation and a pericapsular fibrotic process, which could be responsible for the reduction in IDUA levels observed in the long term. In addition, treated mice developed antibodies against the enzyme. Conclusions. The results selleck chemical suggest that the encapsulation process is effective in the short term but improvements must be achieved in order to LY3023414 mouse reduce the immune response and reach a stable correction.”
“Background/Aims: Using technology-intensive postoperative critical care, interventional radiology and consequent better management of pancreaticojejunal anastomosis (PJA) leaks, the perioperative mortality of pancreaticoduodenal resection (PDR) at high volume Western centers

ranges from 1-5%. Facilities for such sophisticated care are not available in most hospitals in the developing world. We hypothesized that by using an isolated Roux loop for the PJA to minimize the consequences of a leak, it might be feasible to perform PDR with comparable results.\n\nMethodology: From August 1996 to December 2002, 125 consecutive

patients (98 males and 27 females with a mean age of 54 years) with periampullary or pancreatic P005091 manufacturer head carcinomas underwent PDR with the PJA made to an isolated Roux loop of jejunum. A prospectively maintained database was analyzed for perioperative mortality, morbidity, hospital stay and costs.\n\nResults: The perioperative mortality was 7(5.6%) and morbidity 52(42%). Pancreatic fistulae developed in 15(12%) patients and biliary or intestinal fistulae developed in 1(0.8%) patient each. Five (4%) patients underwent relaparotomy. The median hospital stay was 13 days (6-46 days).\n\nConclusions: Using an isolated Roux loop for PJA, centers with limited resources can perform PDR to achieve perioperative outcomes comparable to those reported from more sophisticated centers.”
“The mammalian CNS contains an abundant, widely distributed population of glial cells that serve as oligodendrocyte progenitors. It has been reported that these NG2-immunoreactive cells (NG2(+) cells) form synapses and generate action potentials, suggesting that neural-evoked excitation of these progenitors may regulate oligodendrogenesis.
