With the purpose of detecting spontaneous variation of systolic time intervals (STI), 20 normal subjects have been examined and the STI has been recorded for 5 consecutive days at the beginning of the test and 20, 40 and 60 min afterwards. Significant differences were found for PEP, LVET and the PEP/LVET ratio between observations (p less than 0.05) and… (More)
Prions have been documented in extra-neuronal and extra-lymphatic tissues of humans and various ruminants affected by Transmissible Spongiform Encephalopathy (TSE). The presence of prion infectivity detected in cervid and ovine blood tempted us to reason that kidney, the organ filtrating blood derived proteins, may accumulate disease associated PrP(Sc). We… (More)
The activities of ornithine and S-adenosyl-L-methionine decarboxylase were assayed in the thymuses of adult rats killed at 7-day intervals up to 6 wk after either pinealectomy or sham pinealectomy. The absence of the pineal gland markedly influenced the ornithine decarboxylase activity in the thymus, in which the level of the enzyme was decreased… (More)
Preliminary data obtained in the ambit of Anturan Reinfarction Italian Study (ARIS) show that, in postmyocardial infarction, reduced platelet survival time occurred in hyperbetalipoproteinemic patients treated with placebo, but not in the group of patients treated with sulfinpyrazone (interaction between treatment and lipemic level is at p approximately… (More)
The AA. have compared five different methods for measuring urinary porphyrins (Bio-Rad porphyrins, Porphyrin-T Sibar, Reinkingh-Van Kampen, Schwartz and coll., Fischer-Ham). Based on the results obtained, for total porphyrins the best method appeared to be the Porphyrin-T Sibar test, while for the separate evaluation of uro- and coproporphyrins the most… (More)

Left ventricular function of a sample of subjects with chronic alcohol intake, in the form of wine, and without clinical or electrocardiographic signs of heart disease was compared with that of a sample of normal control subjects using non-invasive polygraphic recordings. The statistical analysis has shown significant prolongation of PEP, PEPI, an increase… (More)
