    Changes in some hemodynamic, endocrine, and metabolic indices in the early postresuscitation period (1979)
    Springer
    Bulletin of experimental biology and medicine 87 (1979), S. 1-4 
    Details
    ISSN: 1573-8221
    Keywords: postresuscitation sickness ; circulation ; gas exchange ; hormones ; isozymes
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract Changes in the systemic circulation, the blood flow in the kidney and limb, and certain endocrine and metabolic indices were studied in 24 dogs subjected to circulatory arrest of maximal severity for 17 min in the course of 9 h of the postresuscitation period. Relative compensation and normalization of certain functions and metabolic indices during the first hour after resuscitation were subsequently followed by a new wave of disorders which developed at different times, unequally, and gradually in the body as a whole and in individual peripheral tissues. Disturbances of the peripheral circulation and central hemodynamics were shown to be among the leading pathological manifestations of postresuscitation sickness.

    Expression of PGK-A in the Australian brush-tailed possum, Trichosurus vulpecula (Kerr), consistent with paternal X inactivation (1979)
    Springer
    Biochemical genetics 17 (1979), S. 325-332

    ISSN: 1573-4927
    Keywords: marsupial ; phosphoglycerate kinase (PGK) ; isozymes ; dosage compensation ; paternal X inactivation
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract An extensive survey of erythrocytes of marsupials other than kangaroos for electrophoretic variation in X-linked enzymes revealed two rare PGK-A phenotypes in the phalangerid Trichosurus vulpecula and one in Trichosurus caninus. Four putatively heterozygous females expressed only the variant allelic isozyme in some tissues but expressed a trace of the normal isozyme in others. A putatively hemizygous male expressed only the variant isozyme in all tissues. The phenotypic patterns were consistent with those observed in kangaroos known to exhibit partial or complete paternal X inactivation in cells of females. Two of the T. vulpecula were a mother and her female pouch young, further suggesting that paternal X inactivation occurs in T. vulpecula. This peculiar mechanism of dosage compensation may not be restricted to kangaroos.

    Linkage, chromosomal association, and expression of Adh-I and Pgm-2 in tomato (1979)
    Springer
    Biochemical genetics 17 (1979), S. 1159-1167 
    Details
    ISSN: 1573-4927
    Keywords: Lycopersicon ; alcohol dehydrogenase ; phosphoglucomutase ; isozymes ; linkage
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The linkage relationship and chromosomal association of two genes in tomato coding for the respiratory enzymes alcohol dehydrogenase and phosphoglucomutase are reported. Also included is a description of where in the life cycle of the plant these genes are expressed. The finding that in pollen and germinating seeds most if not all of the detected activity of these two enzymes apparently arises from these genes suggests that the two isozymes might function in the same respiratory pathway.

    Inheritance of isozyme variation and heterozygosity in Pinus ponderosa (1979)
    Springer
    Biochemical genetics 17 (1979), S. 233-250 
    Details
    ISSN: 1573-4927
    Keywords: isozymes ; inheritance ; linkage ; heterozygosity ; Pinus
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Techniques are presented to detect 23 isozyme loci in the long-lived perennial plant, ponderosa pine. Meiotically derived megagametophyte from seeds is used to examine directly the segregation of allelic variants. Approximately seven seeds were initially examined for 12 enzymes from each of 47 trees from ten stands throughout the northern Rocky Mountain region. Additional seeds were also examined from selected families to confirm the inheritance of observed electrophoretic variants at 13 polymorphic loci and to estimate linkage relationships. Significant nonrandom segregation was consistently detected for three pairs of loci: ADH-1: AAT-2, ADH-1: PGI-1, and LAP-2: 6PG-1. Preliminary estimates of population parameters reveal a relatively high average heterozygosity (H=0.123). This is partitioned into a high amount of genetic variation within local stands, with only approximately 12% of the total heterozygosity resulting from genic differences between stands.

    Evolution of mating systems inLycopersicon hirsutum as deduced from genetic variation in electrophoretic and morphological characters (1979)
    Springer
    Plant systematics and evolution 132 (1979), S. 279-298 
    Details
    ISSN: 1615-6110
    Keywords: Lycopersicon hirsutum ; Solanaceae ; Allozymes ; clinal variation ; electrophoresis ; evolution of mating systems ; isozymes ; self-incompatibility
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract Populations in the central part of the distribution are mostly self-incompatible and tend to be highly variable for allozymic and morphological characters; those in the north and south limits are entirely self-compatible and tend to be genetically highly uniform. Gradations in variability are observed in the intermediate regions. Flower size tends to diminish in the peripheral areas. The extensive differences in genotype observed between the north and south marginal populations are not compatible with the concept of a single origin of self-compatibility, but suggest, along with other evidence, that the substitution of different alleles resulted from differentiation in the marginal areas from older, self-incompatible stocks of the central region. The conclusions regarding patterns of genetic variation and nature of evolution of mating systems inL. hirsutum conform to a remarkable extent with those reached previously forL. pimpinellifolium, a species that is distinct in morphology and ecological preferences yet has a similar latitudinal distribution.
