We tested whether the hydantoin muscle relaxants dantrolene, azumolene, or aminodantrolene could alter the binding of [3H]PN200-110 to transverse tubule dihydropyridine receptors or the binding of [3H]ryanodine to junctional sarcoplasmic reticulum Ca2+ release channels. All three drugs inhibited [3H]PN200-110 binding with azumolene (IC50 approximately 20(More)
The binding properties of [3H]ryanodine, a specific ligand of the receptor complex that forms the Ca2+ release channel of sarcoplasmic reticulum, were studied in normal (N) and malignant hyperthermia-susceptible (MH) human skeletal muscle. Integrity of the solubilized ryanodine receptor was demonstrated by single-channel recordings in planar bilayers and by(More)
Studies of [3H]ryanodine binding, 45Ca2+ efflux, and single channel recordings in planar bilayers indicated that the fatty acid metabolite palmitoyl carnitine produced a direct stimulation of the Ca2+ release channel (ryanodine receptor) of rabbit and pig skeletal muscle junctional sarcoplasmic reticulum. At a concentration of 50 microM, palmitoyl carnitine(More)
In this study, a novel class of polyesters of glycerol, aconitic acid, and cinnamic acid were synthesized along with their hydroxyapatite (HA) composites, and studied for their potential application in bone defect repair. An osteogenic study was conducted with human adipose derived mesenchymal stem cells (hASCs) to determine the osteoinductive ability of(More)
New synthesis techniques are providing increasing control over many inorganic nanoparticle characteristics, facilitating the creation of new multifunctional theranostics. This report proposes the synthesis and testing of a combination nanoparticle comprised of a maghemite core for enhanced T2 MRI contrast diagnostics, a colloidal silver shell acting as an(More)
Culturing cells on thermoresponsive polymers enables cells to be harvested as an intact cell sheet without disrupting the extracellular matrix or compromising cell-cell junctions. Previously, cell sheet fabrication methods using methylcellulose (MC) gel and PNIPAAm were independently demonstrated. In this study, MC and PNIPAAm fabrication methods are(More)
