Drosophila peripheral nerves, similar structurally to the peripheral nerves of mammals, comprise a layer of axons and inner glia, surrounded by an outer perineurial glial layer. Although it is well established that intercellular communication occurs among cells within peripheral nerves, the signaling pathways used and the effects of this signaling on nerve structure and function remain incomple...

The granule cells of the olfactory bulb of the rat have been studied in material prepared by the Golgi-Kopsch method for examination with the light microscope, and in material examined with the electron microscope. With the Golgi method, the granule cells are found to have no process which can be identified as a typical axon, but from the superficial aspect of the somata stout peripheral proces...

An electron microscope study of the myxobacterium Chondrococcus columnaris has revealed the following structures in the peripheral layers of the cells: (1) a plasma membrane, (2) a single dense layer (probably the mucopeptide component of the cell wall), (3) peripheral fibrils, (4) an outer membrane, and (5) a material coating the surfaces of the cells which could be stained with the dye ruthen...

We report a rapid method for the flow cytometric quantitation of phagocytosis in heparinized complete peripheral blood (HCPB), using commercially available phycoerythrin-conjugated latex particles of 1 micron diameter. The method is faster and shows greater reproducibility than Bjerknes' (1984) standard technique using propidium iodide-stained Candida albicans, conventionally applied to the leu...

The peripheral triphenylamine-encapsulated red-emitting iridium(III) complexes have been designed and synthesized. External quantum efficiency over 15% has been realized in single-layer polymer light-emitting diodes, which is the highest ever reported for solution-processed red phosphorescence.

Introduction Transient Receptor Potential Vanilloid subtype 1 or TRPV1 is a peripheral pain target, localized in human sensory neurons, both at the peripheral terminals and in neuronal fibres that carry noxious information up through layer I-II in the dorsal horn of the spinal cord. Several TRPV1 antagonists have been tested in humans. Two specific adverse events, hyperthermia (Gavva 2008) and ...

Following peripheral nerve transection, reorganizational plasticity has been reported to occur in two phases, one immediate and one more protracted. GABA (gamma-aminobutyric acid) has been implicated in the immediate "unmasking" phase of reorganization. We have used quantitative autoradiography to assess potential changes in GABA(A) and GABA(B) receptor binding in primate somatosensory cortex f...
