    The ethylene–carbon dioxide complex: A double internal rotor (1995)

    Notes: A rotationally resolved near-infrared spectrum has been obtained for the ethylene–CO2 van der Waals complex. The structure obtained for this complex has the carbon dioxide lying above the plane of the ethylene molecule, with the CO2 axis parallel to this plane. The individual subbands observed in the spectrum are shifted from the expected rigid rotor positions, indicative of internal rotation of the two monomer units within the complex. A double rotor model is presented that accounts for the shifts and provides an estimate of the barrier to internal rotation. The results indicate that the complex is completely delocalized along the internal rotational coordinate. Ab initio calculations are also presented that are in good agreement with this picture. © 1995 American Institute of Physics.

    Structure of the ethylene dimer from rotationally resolved near-infrared spectroscopy: A quadruple hydrogen bond (1995)

    Notes: Reported here are the first rotationally assigned near-infrared spectra of the ethylene dimer. The vibrational bands observed in this study correlate with ν9 and ν11 of the ethylene monomer, corresponding to C–H stretching motion. The spectral patterns have been identified as due to the vibrational transitions of a symmetric top molecule with D2d symmetry. This structure of the dimer has been predicted by ab initio calculations as the most stable geometry due to the fact that it enables the formation of four equivalent hydrogen bonds. Both vibrational bands show considerable homogeneous broadening corresponding to vibrational predissociation lifetimes of 0.37 and 0.18 ns for ν9 and ν11 excitation, respectively. © 1995 American Institute of Physics.

    Notes: Abstract To study patient compliance in hypertensive outpatients amlodipine (5 mg once daily) and slow release nifedipine (20 mg twice daily) were compared in an open, crossover study in general practices. Four methods of assessment for patient compliance (pill count, taking compliance, days with correct dosing, timing compliance) were used in both study arms. For the latter three assessment a special device, the medication event monitoring system, was used to record the time and date of each opening and closure of the container. The compliance of the 320 hypertensive patients with once-daily amlodipine was markedly superior to twice-daily slow release nifedipine. Therapeutic coverage was also significantly better for amlodipine in the hypertensive patients. Amlodipine was better tolerated than nifedipine slow release. Patient compliance and therapeutic coverage with the calcium antagonist amlodipine given once daily was superior to slow release nifedipine b. d. in hypertensive outpatients recruited in general practice.

    European postmarketing surveillance of ramipril in hypertension (1995)
    Springer
    European journal of clinical pharmacology 49 (1995), S. 73-79

    Notes: Abstract A prospective observational cohort study of the angiotensin inhibitor, ramipril, was undertaken in four countries within the European Community-Netherlands, United Kingdom, Germany and Belgium. A total of 10,377 consecutive patients with essential hypertension were recruited to the study with the aim of follow-up for one year. Overall 37% of doctors who agreed to participate in the study actually enrolled at least one patient. One third of the doctors who enrolled patients in the study entered two thirds of patients studied. Some 15% of participating males and 27% of females were aged over 70 years. Newly diagnosed hypertensives comprised 22% of the study cohort, the proportion being highest in UK and Netherlands, whereas 53% were established hypertensives of two or more years' duration, the proportion being highest in Germany and Belgium. There were substantial differences among the participating countries in the concurrent treatment these patients were receiving for hypertension, with two or more co-therapies being most frequent in Germany and Belgium. There were also substantial differences in co-therapies for concurrent diseases among the participating countries, reflecting both standard therapeutic practices in local areas and differences in marketing of drugs in the different countries. This report describes the initial findings of this multinational study and emphasises the need to consider several major potentially confounding variables in the analysis of the outcome events both in this study and in other collaborative observational international monitoring schemes for adverse drug reactions.

    Ovary, seed and fruit ofRutidea (Rubiaceae, Pavetteae) (1995)
    Springer
    Plant systematics and evolution 196 (1995), S. 1-17

    Keywords: Rubiaceae ; Pavetteae ; Rutidea ; Nichallea ; Ovary ; incomplete septum ; placentation ; obturator ; campylotropous ovule ; fruit ; seed development ; rumination

    Topics: Biology
    Notes: Abstract The ovary ofRutidea is bicarpellate and incompletely bilocular (septum between locules not continuous). A solitary campylotropous ovule, ascending from a basal placenta, occurs in each locule. Based on their orientation and degree of curving, three ovule types are distinguished. As a consequence of the abortion of one ovule, the drupaceous fruits are one-seeded. The incomplete septum allows the spherical seed to fill out the entire interior of the fruit. The seeds are deeply ruminate (Spigelia type). They grow very fast, producing folds and undulations (ruminations) which invade and totally occupy the second locule, almost enveloping the aborted ovule. Comparisons with otherRubiaceae (especiallyPavetteae), show that hemianatropy and campylotropy occur more often in theRubiaceae than hitherto accepted. The study corroborates the close affinity betweenRutidea andNichallea.
