Octopaminergic sensitivity of the glia that form the blood—brain barrier of the cockroach was examined using microelectrode recordings of the potential developed across this barrier layer, the perineurium. Exposure to 10~moll~ DL-octopamine had no significant effect upon the changes in potential induced by substitution of Tris for external sodium. Treatment with concentrations ranging from 10~m...

This investigation was designed to determine whether nano-sized manganese oxide (Mn-40 nm) particles would induce dopamine (DA) depletion in a cultured neuronal phenotype, PC-12 cells, similar to free ionic manganese (Mn(2+)). Cells were exposed to Mn-40 nm, Mn(2+) (acetate), or known cytotoxic silver nanoparticles (Ag-15 nm) for 24 h. Phase-contrast microscopy studies show that Mn-40 nm or Mn(...

AIMS The complement factor H (CFH) is a regulator for the alternative pathway. prevalence and roles of anti-CFH antibodies in clinical outcome primary membranous nephropathy (MN) patients remain unclear. MATERIALS AND METHODS A total 106 biopsy-proven kidney disease 18 healthy controls were retrospectively investigated this study. 36 had MN 70 diseased (31 minimal change nephrotic syndrome (MCN...

background: about 83% of patients with breast cancer (bc) undergo radiation therapy. these patients show various degrees of mild to acute reactions during and after the completion of treatment.the aim of this study was to compare inherent radiosensitivity of gamma-irradiated g0-lymphocytes between bc patients and normal individuals using cytokinesis blocked micronucleous assay. methods: three t...

Swimming effort and oxygen consumption of newly emerged green turtle Chelonia mydas hatchlings was measured simultaneously and continuously for the first 18 h of swimming after hatchlings entered the water. Oxygen consumption was tightly correlated to swimming effort during the first 12 h of swimming indicating that swimming is powered predominantly by aerobic metabolism. The patterns of swimmi...
