    Amphipathic antigen from Actinomyces viscosus (1984)
    Oxford, UK : Blackwell Publishing Ltd
    FEMS microbiology letters 21 (1984), S. 0 
    Details
    ISSN: 1574-6968
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Abstract Amphipathic antigen (AcA) was extracted with phenol solution from whole cells of Actinomyces viscosus, and purified by gel filtration on Sepharose 6B. From the results of the gel diffusion test and passive hemagglutination assay, AcA was shown to be present as the cell-surface antigen.

    Stereotactic CT scan applied to stereotactic thalamotomy and biopsy (1984)
    Springer
    Acta neurochirurgica 71 (1984), S. 55-68 
    Details
    ISSN: 0942-0940
    Keywords: CT scan ; Stereotactic thalamotomy ; biopsy ; depth recording ; craniometry
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary A Stereotactic method to visualize deep subcortical structures through which the electrode would pass intraoperatively is described in detail. The procedures are: 1) Approximation of the tentative target point in the lateral craniogram according to some craniometric data. 2) Determination of the invading route and its transfer to the patient's scalp. 3) CT scanning by a new generation scanner to distinguish between gray and white matter along the predetermined plane. 4) Intraoperative adjustment of the electrode to the predetermined CT image and error correction. 5) Verification by recording electrical activities in subcortical tissue. This simple method would be of great benefit for the accurate and safe performance of Stereotactic thalamotomy and biopsy.

    Studies on separation mechanisms of biological molecules on a polyvinyl alcohol column (1984)
    Springer
    Chromatographia 18 (1984), S. 550-555 
    Details
    ISSN: 1612-1112
    Keywords: Liquid column chromatography ; Size-exclusion chromatography ; Reversed-phase chromatography ; Polyvinyl alcohol column
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology
    Notes: Summary The chromatographic separation mechanism on a polyvinyl alcohol (PVA) column in aqueous systems was explored utilizing several different types of compound such as polyethylene glycols, carbohydrates, pyrimidine and purine bases, fatty acids, monophosphate nucleotides and glycyl-peptides. Two types of separation mechanisms were found to occur for these substrates. The polyethylene glycols and the carbohydrates were eluted by size-exclusion chromatography. The retention behavior of the other substrates could be explained by the solvophobic theory, suggesting that the predominant separation mode was reversed-phase chromatography. The occurrence of reversed-phase chromatography was also indicated by the remarkable effect of the addition of ion-association reagents to the chromatographic system on the retention of the monophosphate nucleotides.
