Various fluorescent molecular probes have been injected into the cytoplasm of nectary trichome cells of Abutilon striatum to ascertain the conductivity of the plasmodesmata. Most of the probes were based on fluorescein conjugated to a range of amino acids and peptides. The probes are not broken down by cytoplasmic enzymes during the period of observation.(More)
The large conductance K+ channel in the tonoplast of Chara corallina has subconductance states (substates). We describe a method that detects substates by monitoring the time derivative of channel current. Substates near to the full conductance tend to have long durations and high probabilities, while those of smaller amplitude occur with less probability(More)
The cDNA for the green fluorescent protein (GFP) of Aequorea victoria has been expressed in transformed cells of Saccharomyces cerevisiae and the recombinant GFP isolated. Protonation and deprotonation of the cloned and purified GFP produced major effects on its spectral absorption characteristics with an increase in pH enhancing the fluorescence emission(More)
The characteristics of cation outward rectifier channels were studied in protoplasts from wheat root (Triticum aestivum L. and Triticum turgidum L.) cells using the patch clamp technique. The cation outward rectifier channels were voltage-dependent with a single channel conductance of 32 +/- 1 picosiemens in 100 millimolar KCl. Whole-cell currents were(More)
This report details preliminary findings for ion channels in the plasma membrane of protoplasts derived from the cotyledons ofAmaranthus seedlings. The conductance properties of the membrane can be described almost entirely by the behavior of two types of ion channel observed as single channels in attached and detached patches. The first is a(More)
Surgical ligation clips of various materials were scanned in a water-filled phantom to determine what artifacts would be produced. Tantalum clips produced severe image degradation, while stainless steel clips produced less severe degradation. Minimal artifacts were observed with titanium clips. Clips molded from an absorbable polymeric material,(More)
The aim of the present study was to evaluate, by use of fluorescence microscopy and immunofluorescence stainings, the use of a fluorescent membrane potential sensitive probe as a means to identify and monitor changes in membrane potential of individual cell types in whole islets of Langerhans over time. Our work supports the use of the fluorescent probe(More)

An incisive canal cyst was misdiagnosed as an endodontic lesion. The patient's chief complaint was pain on mastication with increasing intensity for the last 2 days. The single original periapical radiograph revealed a well-circumscribed radiolucency related to the apex of the maxillary right central incisor. The patient was referred with a request for(More)
Using the enormous magnetic field gradients present near the surface of magnetic recording media, we assemble diffraction gratings with lines consisting entirely of self-assembled magnetic nanoparticles that are transferred to flexible polymer thin films. These nanomanufactured gratings have line spacings programmed with commercial magnetic recording and(More)
