Prevalence and risk factors for Chlamydia trachomatis infection in pregnant women.

The aim of this study was to determine the prevalence and risk factors for Chlamydia trachomatis infection in pregnant women. A total of 351 asymptomatic pregnant women (first to second trimesters; age range: 15-30 years) were examined. The background data related to social and marital status, age, anamnestic data were also recorded.

[Interaction between spindles evoked by electric stimulation of different regions of the cerebral cortex].

In unanesthetized immobilized cats, under repeated administration of small doses of nembutal (2-3 mg/kg), connections between the projection and the parietal associatition cortical areas was studied as well as the interaction between spindles elicited by stimulation of these areas. Stimulation of the primary sensory areas (auditory or somatosensory) was shown to be able to elicit spindles not only in the stimulated area but in the association cortex too. This latter spindle, being kind of induced from the sensory areas, interacts with the spindles elicited by the direct electrical stimulation on the association cortex.
