Valence photoionization dynamics in circular dichroism of chiral free molecules: the methyl-oxirane.

The dynamical behavior of circular dichroism for valence photoionization processes in pure enantiomers of randomly oriented methyl-oxirane molecules has been studied by circularly polarized synchrotron radiation. Experimental results of the dichroism coefficient obtained for valence photoionization processes as a function of photon energy have been compared with theoretical values predicted by state-of-the-art ab initio density-functional theory. The circular dichroism measured at low electron kinetic energies was as large as 11%. Trends in the experimental dynamical behavior of the dichroism coefficients D(i)(omega) have been observed. Agreement between experimental and theoretical results permits unambiguous identification of the enantiomer and of the individual orbitals.

[Mortality of psychiatric patients. A retrospective cohort study of in-patients at the Psychiatric Hospital of Reggio Emilia].

The authors report the results of historical cohort study in long-term patients of psychiatric hospitals in Reggio Emilia. The cohort was formed by 790 patients hospitalized before 1978, and has been followed-up until 31/12/'89. The results of the study are: 269 subjects deceased (34%); 117 discharges (14.8%) and 411 (52.1%) still in hospital on 1/1/'90. An excess mortality was observed in the cohort. Mortality appears to be particularly high among young patient and females.

[Intracoronary thrombolytic treatment with urokinase in myocardial infarct: clinical angiographic findings and effects on left ventricular function].

The effect of selective intracoronary thrombolysis was studied in 27 patients with evolving myocardial infarction. In the acute phase, angiography demonstrated complete occlusion in 22 cases (81,5%) (group A), and incomplete stenosis with diminished distal blood flow in 5 cases (18,5%) (group B). Urokinase was infused into the infarct-related coronary artery at a rate of 8000 u/min u/min until reperfusion was obtained and subsequently at a rate of 2-4000 u/min for 20-40 min. In group A, coronary recanalization was achieved in 18 of 22 patients (81,8%) (group A1), while in 4 patients (group A2) the procedure was unsuccessful. Group B patients showed no angiographic modifications following fibrinolytic therapy. Left ventricular function was studied during the acute phase (before and after therapy) in 9 patients; 22 patients were studied immediately after thrombolysis and before hospital discharge. Preliminary studies of patients in group A1 after reperfusion showed a decrease in telediastolic pressure from 18,9 to 24,4 mmHg and an increase in ejection fraction from 0,40 to 0,43 (p = ns). No modifications in these parameters were observed in group A2 or B. Follow-up examination of group A, revealed an increase in ejection fraction from 0,40 +/- 0,12 to 0,50 +/- 0,15 (p less than 0,05) and a decrease in the length of the akinetic segment from 6,49 +/- 2,4 to 4,40 +/- 1,35 (p less than 0.05). In group B, the ejection fraction increased from 0,41 +/- 0,06 to 0,50 +/- 0,04 (p less than 0.05) and the length of the akinetic segment decreased from 7,52 +/- 2,0 to 3,38 +/- 1,14 (p less than 0.05). On the contrary, in group A2, ejection fraction diminished from 0,39 +/- 0,06 to 0,34 +/- 0,07 and the length of the akinetic segment remained unchanged. Our results suggest that: A) coronary artery thrombosis is frequent in evolving myocardial infarction B) selective intracoronary thrombolysis and subsequent reperfusion of the infarcted area is readily obtainable with urokinase infusion C) no significant acute modifications of left ventricular function were observed D) 2-3 weeks after initial treatment, patients in which recanalization of an occluded vessel was achieved (group A1) and patients that presented with subocclusive stenosis and reduced blood flow (group B), showed an improvement in left ventricular function and a reduction in the akinetic area.

[Acting out and schizoid personality].

The Authors examine the crime-symptoms, sole index of an asymptomatic clinic history, and make some remarks on the indexes of social dangerousness. By this point of view, the structural traits of pre and post-critic personality seem to be a first predictory index. In relation to this question the Authors make mention to schizoidia.
