The effects of lithium sulphate following acute administration to Wistar rats - in therapeutic and toxic doses - were investigated, using as markers the levels and turnover of brain, kidney and liver nucleotides. Adenine- and guanine-dependent nucleotides were assayed concomitantly, using a high- performance liquid chromatographic method. Following acute administration, lithium's effects on 3',...

This paper studies the asymptotic stability of a repairable system with repair time of failed system that follows arbitrary distribution. We show that the system operator generates a positive C0-semigroup of contraction in a Banach space, therefore there exists a unique, nonnegative, and time-dependant solution. By analyzing the spectrum of system operator, we deduce that all spectra lie in the...

Learning structure of Bayesian network have been a great challenge of Machine learning for the last few decades. A lot of ideas have been offered during that time and some of them proved to provide pretty handy results. The new idea of ordering estimation is proposed aiming to improve properties of ordering based or dependant Bayesian network structure learning algorithms. Three different appro...

The recent advances in Human-Computer Interaction and Artificial Intelligence have significantly increased the importance of identifying human emotions from different sensory cues. Hence, understanding underlying relationships between cues become a subject study many fields including Acoustics, Psychology, Psychiatry, Neuroscience Biochemistry. This work is preliminary step towards investigatin...

The paper presents a new approach to the ECG compression algorithms. The idea of non-equal density of medical information in the electrocardiogram yields the new design guidelines for a compression system. The distortions of reconstructed signal, considered as unavoidable result of data reduction in other traditional systems, are now subject to control. The temporal distribution of distortions,...

A retrospective study of 85 children with non-Hodgkin' s lymphoma diagnosed and treated in the period of 1963-1974 was undertaken to asses clinical characteristics, pronostic factors and survival. This malignancy was more frequent in males between ages 3 and 4. The histopathologic diagnosis revealed a lymphosarcoma lymphoblastic predominance (77.6%). The clinical extent at diagnosis was 14% for...

The plants of genus Corchorus have a folkloric repute to possess anti-inflammatory activity. The crude ethanolic extract of Corchorus fascicularis Lam. (CFE) was screened for presence of anti-inflammatory, free radical scavenging and calcium channel blocking (CCB) activities to validate its vernacular use. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) assay was used to assess free radical scavenging...
