    Activation of Protein Kinase C by the Capsaicin Analogue Resiniferatoxin in Sensory Neurones (1995)

    Notes: Abstract: Resiniferatoxin and capsaicin are sensory neurone-specific excitotoxins that operate a common cation channel in nociceptors. Resiniferatoxin is structurally similar to capsaicin and to phorbol esters. Specific [3H]-resiniferatoxin binding, which was detected in the membrane (KD value 1.8 ± 0.2 nM) but not cytosolic fraction of rat dorsal root ganglia, could not be displaced by phorbol 12,13-dibutyrate. Conversely, resiniferatoxin did not displace [3H]phorbol 12,13-dibutyrate binding in either the cytosolic or membrane fraction. Resiniferatoxin and capsaicin both caused translocation of protein kinase C in dorsal root ganglion neurones (EC50 value 18 ± 3 nM). This translocation was greatly reduced but not abolished, in the absence of external Ca2+, suggesting that it was secondary to Ca2+ entry. Resiniferatoxin also caused direct activation of a Ca2+- and lipid-dependent kinase (or kinases) in the cytosolic fraction of dorsal root ganglia, at concentrations (100 nM to 10 µM) higher than required for displacement of [3H]resiniferatoxin binding or translocation of protein kinase C. Capsaicin (up to 10 µM) was unable to mimic this effect. These data imply that although resiniferatoxin-induced translocation of protein kinase C in dorsal root ganglion neurones was mainly indirect, it also caused direct activation of a protein kinase C-like kinase in these cells.

    A Comparison of Distribution Between Simultaneously or Sequentially Delivered Antegrade/Retrograde Blood Cardioplegia (1996)

    Notes: Abstract Commercially available cardioplegia delivery systems now allow for antegrade (aortic root, coronary ostia, saphenous vein graft) perfusion to occur either sequentially or simultaneous with retrograde (coronary sinus) perfusion. This study was designed to compare the total flow and local distribution of sequential versus simultaneous antegrade/retrograde cardioplegia delivery. Methods: Explanted human hearts diagnosed with idiopathic cardiomyopathy underwent a cold cardioplegic arrest and bicaval cardiectomy. Thirty-seven degree centigrade blood cardioplegia containing colored microspheres was then delivered antegrade (red color) at a pressure of 80 mmHg or retrograde (blue color) at a pressure of 40 mmHg. In the sequential group (n = 6), cardioplegia was delivered antegrade and then retrograde for 2 minutes, respectively. For the simultaneous group (n = 6), cardioplegia was delivered both antegrade and retrograde for 2 minutes. The ventricular myocardium was then sampled at 12 representative sites to determine regional cardioplegic flow. Results: Mean total cardioplegia delivery/minute was 0.69 ± 0.62 mL/g per minute for sequential cardioplegia, and 0.46 ± 0.19 mL/g per minute for simultaneous cardioplegia (p 〉 0.05, NS). At the 12 ventricular sites sampled, mean regional cardioplegic flow (mL/g per min) was in general slightly greater for sequential delivery. However, this was not statistically significant (p 〉 0.05, NS). Conclusion: The data suggest that there may be a slight advantage in total cardioplegia delivery and regional cardioplegia delivery when using sequential rather than simultaneous cardioplegia delivery. However, this difference was not statistically significant and is likely not of clinical significance. Therefore, we would recommend using either sequential or simultaneous antegrade/retrograde cardioplegia based upon whichever technique facilitates the conduct of the individual operation.

    Temporary Mechanical Support with the BVS 5000 Assist Device During Treatment of Acute Myocarditis (1997)

    Notes: Abstract Background: Ventricular support with the BVS 5000 (Abiomed) has been used as temporary circulatory assist for the failing heart. Our purpose is to summarize four cases illustrating the role of mechanical unloading in acute myocarditis. Methods: Four patients aged 16- to 33-year old presented with congestive heart failure 4 to 20 days after a flu-like syndrome. All patients were in severe cardiogenic shock ± renal and liver dysfunction. Ejection fraction ranged from 5% to 26%. Indications for ventricular assist were failure of maximal medical treatment with 〈inlineGraphic alt="geqslant R: gt-or-equal, slanted" extraInfo="nonStandardEntity" href="urn:x-wiley:08860440:JOCS55:ges" location="ges.gif"/〉 two inotropes ± intra-aortic balloon pump. Myocardial biopsy revealed acute myocarditis in three patients and severe edema in one despite a characteristic clinical course. Two patients received immunotherapy with OKT3. Biventricular assist was used in three patients and left ventricular assist only was used in one. Mean support time was 8.3 days (7 to 11). Results: All patients had recovery of myocardial function and were discharged from the hospital in good condition. Conclusion: The BVS 5000 device provides a safe, simple, and effective method to support the circulation during acute myocarditis. We hypothesize that this may facilitate myocardial recovery by decompressing the distended ventricle. Ventricular assist devices should be used early in the presence of hemodynamic deterioration on maximal medical therapy.

    Stationary carbon cathodic arc: Plasma and film characterization (1996)

    Notes: The plasma characteristics of a new arc mode on carbon referred to as the "stationary cathodic arc'' are reported. Particularly, optical emission spectroscopy, probe and ion energy distribution measurements are used to compare the properties of the stationary arc with the normal "random cathodic arc'' on carbon. The measurements revealed that the plasma properties of both arc modes are similar. In addition, we have correlated the plasma characteristics to the film properties. Carbon films deposited using the stationary arc were found to have a surface particle density equivalent to those deposited using the filtered cathodic vacuum arc. The macro-particle free films were found to be highly tetrahedral and compressively stressed. Both the sp3 fraction and stress values were strongly dependent on the ion energy with maximum values of 85% and 9.4 GPa, respectively, occurring at ≈50 eV. © 1996 American Institute of Physics.

    Pure silicon plasma in a helicon plasma deposition system (1997)

    Notes: A plasma containing only silicon atoms and ions has been obtained by electron-beam evaporation of solid silicon through a helicon rf plasma source. The density of the silicon plasma in the diffusion chamber is 3–5×1010 cm−3, and the electron temperature 12 eV. These plasma conditions correspond to a predicted deposition rate from silicon ions of 230±60 nm/min, comparable to the deposition rate of 250 nm/min obtained using the same evaporation conditions, without generating a plasma. The large contribution of silicon ions, the high deposition rate, and the absence of other species such as hydrogen or argon, leads to novel conditions for plasma assisted deposition. © 1997 American Institute of Physics.

    Deposition of smooth tetrahedral amorphous carbon thin films using a cathodic arc without a macroparticle filter (1995)

    Notes: It is shown that for a cathode consisting of compressed graphite powder, the cathodic arc discharge is confined within deep erosion holes and the macroparticle emission is greatly reduced. Electron energy loss spectroscopy and scanning electron microscopy show that smooth tetrahedral amorphous carbon films with up to 85±10% sp3 bonding can be deposited without the use of magnetic filters. The new carbon arc discharge process holds potential for deposition of smooth tetrahedral amorphous carbon films on large area substrates due to the elimination of the magnetic filtering stage. © 1995 American Institute of Physics.

    Sanitizing Effects of Fruit Waxes at High pH and Temperature on Orange Surfaces Inoculated with Escherichia coli (1999)

    Notes: We determined the bactericidal activity of surface applied waxes on oranges. Effective bactericidal activity of combined alkali and heat treatments was observed on both glass slides and orange fruit surfaces. A five log reduction of Escherichia coli was attained by dipping inoculated glass slides in heated (≥50°C) alkaline (pH 10) wax solution for 4 min. A pH 11, dipping at ≥50°C for ≥2 min achieved similar bactericidal effects. On the fruit surface, wax treatments were effective at the non-stem scar area. Thus, applied fruit waxes may be useful on raw agricultural commodities to reduce surface microbial contaminants.
