    Chlorophyll Catalysis of Fat Peroxidation (1964)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 29 (1964), S. 0

    Notes: Peroxide apparently occurring in freshly prepared sausage was traced to the catalytic effect of chlorophyll in the sage after fat extraction. The extracts were exposed to ordinary laboratory illumination a day before analysis. No peroxide appeared in extracts of the pork fat alone, nor in extracts of the sage alone. But mixtures of fat extract with sage extract developed peroxide. Extracts of green leafy material from other species and purified chlorophyll likewise developed peroxide with fat extracts. This effect is ascribed to the porphyrin structure. Extracts containing fat and chlorophyll should be kept in the dark until peroxide estimation.

    Effect of Para-chlorophenoxyacetic Acid (PCPA) Spray on Composition and Residue in Boysenberries (1964)

    Notes: The effect of para-chlorophenoxyacetic acid (PCPA) spray on the chemical composition of boysenberries was investigated. A 100-ppm spray of PCPA 46 days before harvest produced berries 10-15% larger and heavier than the control sample. Total yield was 9% higher for the sprayed sample than for the control. The acids, soluble solids, and ascorbic acid contents of the berries varied somewhat with date of harvest and ripeness level. A gas-liquid chromatographic method was used to determine PCPA as a C14-labeled methyl ester on a column made of 20% Dow 11 high-vacuum silicone grease on Chromosorb. The method can detect .05 ppm PCPA in a 100-g sample. Boysenberry plants sprayed once, 46 days before harvest, showed a residue of 0.09 ppm in the berries, whereas those sprayed twice, at 46 and 33 days before harvest, showed a residue of 0.26 ppm.

    Reticulo-Endothelial Activity in Mice Infected with Plasmodium vinckei (1964)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 11 (1964), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: SYNOPSIS. The effect of P. vinckei infections on the phagocytic activity of the reticulo-endothelial system in mice has been investigated. Changes occurring in the pattern of R.E. activity show that there is slight stimulation of phagocytosis 24 hours after the initiation of the infection at which time parasites appear in the blood. The stimulation continues and reaches a peak on the 3rd day, following which it drops to subnormal levels by the 6th and 7th days when the animals die. The parasitaemia rises abruptly from the 4th day onwards, this increase bearing a direct relationship to the fall in the level of phagocytic activity. The changes which occur during this infection are compared with those previously reported for Plasmodium gallinaceum in chicks.

    Anomalous Serotypes in Tetrahymena (1962)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 9 (1962), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: SYNOPSIS. Novel serotypes appeared among the F2 progeny of a single cross involving alleles at the H locus. Two of the clones manifesting aberrant types have been subjected to breeding analysis. The aberrant phenotypes disappear at conjugation and have not been recovered in either F1 or F2. Comparable types have not been found again in large scale crosses involving a variety of different H alleles. The basis for the unusual types remains obscure.

    Reticulo-Endothelial Activity in Haemamoeba (=Plasmodium) gallinacea Infections (1963)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 10 (1963), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: SYNOPSIS. The effect of H. gallinacea infection on the phagocytic activity of the reticulo-endothelial system in chicks has been investigated. Changes occurring in the pattern of R.E. activity show that there is initial stimulation of phagocytosis within 24 hr and that this increases up to the 4th and 5th days after which time parasites appear in the blood. Thereafter there is a rapid drop in R.E. activity with a proportional increase in parasitaemia following which death ensues. The importance of the protective value of the reticulo-endothelial system is indicated and it is suggested that a toxin produced by the parasites or by their break-down products is the likely cause of phagocytic depression.

    The Inheritance of H-L Serotype Differences at Conjugation in Tetrahymena (1963)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 10 (1963), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: SYNOPSIS. Cells of variety 1, Tetrahymena pyriformis, manifest different immobilization antigens when grown at 15d̀ and 25d̀C. These differences are partially maintained for a period of growth at an intermediate temperature. Crosses were performed at intermediate temperatures between parental cultures conditioned to high and low temperatures and the antigenic characteristics of their progeny were determined. When conjugation is abortive and paired cells do not complete conjugation, the cells separate and produce clones with distinctive serotypes. When conjugation is completed, however, no systematic differences between exconjugants can be demonstrated. These results differ from those obtained under comparable circumstances in Paramecium aurelia, and fail to support the idea that the cytoplasm plays a significant role in the maintenance of serotypes in Tetrahymena.

    Nuclear Misbehavior in an Aberrant Inbred Tetrahymena (1964)
    Oxford, UK : Blackwell Publishing Ltd
    The @journal of eukaryotic microbiology 11 (1964), S. 0 
    Details
    ISSN: 1550-7408
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: SYNOPSIS. Breeding anomalies in an inbred strain (B1) of syngen 1, Tetrahymena pyriformis, are traced to aberrant chromosomal constitutions of the micronuclei. The origins of the micronuclear defects have not been established, but they probably arise in much the same manner as those observed earlier in “semi-amicronucleate” clones, except that they occur later and in lower frequencies. The abnormal nuclei are impaired in their ability to carry out the maneuvers required for normal conjugation; some are blocked in MI, most after MII; the occasional cells in which nuclear reorganization is completed have visibly defective macronuclear anlagen and are inviable. When crossed to normal strains, nuclear misbehavior is induced in them and again very few if any viable exconjugants are produced. The details of the aberrations are discussed with reference to the patterns of nucleocytoplasmic interaction in conjugation.
