Seven patients with craniosynostosis (mean age 8 years, Apert syndrome, n = 4, Crouzon's disease, n = 3) underwent lengthening of the skull by gradual bone distraction. Three patients (group A) were treated by coronal craniectomy reaching the orbital fissure and gradual bone distraction. The other four (group B) underwent monobloc craniofacial disjunction(More)
OBJECTIVES This study sought to assess the usefulness and accuracy of artificial neural networks in the prognosis of 1-year mortality in patients with heart failure. BACKGROUND Artificial neural networks is a computational technique used to represent and process information by means of networks of interconnected processing elements, similar to neurons.(More)
Male Wistar rats were tested for sensitivity to audiogenic seizures (AS; 110 dB), using an audiogenic severity index (SI). Sensitive (S) animals were subjected to bilateral lesion of the inferior colliculus (IC) and/or the lateral lemniscus (LL). Resistant (R) animals were subjected to bilateral lesions of the IC, unilateral sequential lesions of the(More)
Stereotaxic electrolytic lesions were made in the dorsomedial telencephalic area, laterally to the dorsal commissure, in male Siamese Fighting Fish (Betta splendens). The startle and orienting responses to regularly delivered taps on the side of the aquarium were recorded for lesioned, sham-operated and unoperated groups. Lesioned fish showed increased(More)
1. A stereotaxic technique for electrode positioning in the telencephalic nuclei of the Siamese Fighting fish (Betta splendens) is described. 2. The forebrain atlas was based on paraffin-embedded, in situ-sectioned, Nissl-stained material. Brain measurements were corrected for tissue shrinkage due to histological procedures. The atlas and methods have(More)
Wistar-derived male rats were tested for audiogenic seizure (AS) susceptibility, and classified into sensitive (S) and resistant (R) groups. Rats from group R underwent unilateral ablation of the telencephalon, or were detelencephalated (HD), or sham-lesioned, and were tested for audiogenic susceptibility one month and one year after surgery. It was found(More)
The audiogenic crisis (AC) includes an initial phase of bursts of circular, stereotyped running. Since it has been shown that the nigrostriatal system is important in the control of lesion- and drug-induced stereotyped rotational behavior, the effects of unilateral electrolytic lesions of the substantia nigra (SN) on the AC were investigated. Behavior was(More)
The effects of REM sleep deprivation (REMSD) for 96 h on discriminated avoidance learning were tested in rats using three different task topographies:in a jumping-box, in a shuttle-box and bar-pressing. The same stimulus relationship and the same methodological controls with regard to the avoidance schedules and to the platform technique were employed.(More)
