An analysis of the central projections of the ventral nucleus of the trapezoid body (VNTB) in the rat, a region of the superior olivary complex known for its neuronal heterogeneity, was made using two anterograde axonal tracers, [3H]leucine and biotinylated dextran amine (BDA). A mixture of these tracers was injected iontophoretically into the VNTB and the(More)
OBJECTIVES To investigate possible relations between respiratory health and past airborne exposure to refractory ceramic fibres (RCFs) and respirable dust in workers at six European factories, studied previously in 1987. METHODS The target population comprised all current workers associated with RCF production, plus others who had participated in 1987(More)
BACKGROUND Intraoperative awareness in patients undergoing general anesthesia is an infrequent but well-described adverse outcome. The reported incidence of this phenomenon is between 0.1% and 0.9%. METHODS With institutional review board approval, the authors reviewed continuous quality improvement data from 3 yr (2002-2004) at the locations where the(More)
The purpose of the present work was to elaborate a method of investigation of the instrumental CRs with sexual reinforcement. The examination of such reflexes in various experimental situations gives more precise information about sexual drive levels than simple observation of sexual behavior. Moreover, this is the only way for obtaining exact data(More)
In a previous study (1) during the investigation of the mutually reinforced instrumental sexual rqponses in rats a positive correlation has been found between the male and female response latencies. The purpose of the present work was to investigate whether this correlation is related to the mating behavior. Mutually reinforced instrumental responses,(More)
The bar-press response reinforced by the contact with estrus female was investigated in growing male rats. The bar-press latency as well as the subjects' behavior changed distinctly in the course of the study with the increase of experience and maturation of the subjects. Some behavioral items such as, nasogenital contact, climbing on the head, and running(More)
The metabolic effects of intravenous cyclosporine on lipids and lipoproteins were studied in 29 allogeneic bone marrow recipients compared with 13 autologous bone marrow patients not requiring cyclosporine therapy. Patients were monitored continuously from 5 days prior to 27 days following transplantation; cyclosporine treatment was initiated 4 days before(More)
The hippocampal EEG activity was recorded in male rats during the response-contingent reinforcement of a female. The instrumental response was a bar-pressing on a fixed-ratio-10 reinforcement schedule. The frequency of bar-pressing tends to increase during the succeeding copulatory series. The similar phenomenon was observed in the frequency of the(More)
