    Increased myocardial contractility in short-term Type 1 diabetic patients: an echocardiographic study (1985)

    Notes: Summary Cardiac function was investigated by echocardiography in 24 short-term Type 1 diabetic patients with a mean diabetes duration of 7 years (range 4–14 years) during conditions of ordinary metabolic control. Compared to 24 age and sex matched normal control subjects, measurements of myocardial contractility as left ventricular fractional shortening and mean circumferential shortening velocity were increased by 12% and 20% respectively. Another 8 Type 1 diabetic patients were examined during conditions of poor (hyperglycaemia and ketosis) and good metabolic control. Following improved glycaemic control, left ventricular fractional shortening and mean circumferential shortening velocity decreased by 16% and 24% respectively. Our findings show that short-term Type 1 diabetes is associated with increased myocardial contractility. Furthermore, this condition is related to the state of metabolic control.

    Collision-induced dissociation of C60-: Effect of energy-coupling processes on the dissociation dynamics (1995)
    New York, NY : Wiley-Blackwell

    Notes: Dissociation of C60- ions induced in 30 keV collisions with atomic and molecular gases has been studied. The pattern of negativeion formation from C60- precursors is found to be distinctly different from that obtained for positive-ion fragments from C60+ precursors in that the collision-induced dissociation spectrum in the former case is dominated by small negative clusters, presumably of linear geometry, Simple arguments utilizing the relationship of electrostatic properties of different molecular structures to their electron affinities and ionization energies have been invoked to rationalize these observations. The difference in the dissociation dynamics of C60- and C60+ ions is discussed in terms of competition between different energy-coupling schemes involving either electronic degrees of freedom or nuclear (vibrational) degrees of freedom.

    Resonance Raman spectrum of the transient dimethylsulfide dimer radical cation |(CH3)2S|2+· (1981)

    Notes: The resonance Raman spectrum of the transient thioether radical cation dimer complex |(CH3)2S|2+·, generated by electron irradiation of an aqueous solution of dimethylsulfide and recorded by optical multichannel detection, is reported. Vibrational bands at 276 cm-1 and 139 cm-1 were detected and are assigned to the stretching mode of the quasi-three-electron S—S bond and a δ(CSS) deformation mode, respectively.
