    Genetic Analysis of Resistance to Phytophthora Root Rot in Tomato (Lycopersicon esculentum Mill.) (1991)

    Notes: The resistant accession, LA1312, and the susceptible cultivar ‘Peto 343′, were crossed to develop F1, F2 and BC1 populations for genetic analysis of resistance in tomatoes to Phytophthora parasitica Dastur, the causal agent of Phytophthora root rot. There was no maternal effect on resistance. Generation means analysis indicated that tolerance to Phytophthora root rot was under genetic control with both simple (additive and dominance) and digenic interaction (additive × additive and additive × dominance) effects contributing to the total genetic variation among generation means. Weighted least square regression analysis indicated that the majority (ca. 96 %) of the genetic variation could be explained by simple additive effects alone. Narrow sense heritability was estimated as 0.22. Based on effective factor formulae, at least five effective factors controlled the resistance. Implications for breeding procedures are discussed.

    Morphology and staining patterns of endocrine cell tumours in the gut, pancreas and bronchus and their possible significance (1977)
    Oxford, UK : Blackwell Publishing Ltd

    Details

    Topics: Medicine
    Notes: We have studied 109 endocrine cell tumours of the gastrointestinal tract, pancreas and bronchus in terms of histological pattern and histochemical staining with immunocytochemical studies on seven tumours. As a result we believe that previous histological classifications need modification. 5-Hydroxytryptamine secreting tumours have a carcinoid (A1) pattern with in some cases, an additional tubuloacinar element (A1A2) and definable histochemical reactions; well differentiated gastrinomas, insulinomas and glucagonomas are associated commonly, but not exclusively, with particular histological patterns and argyrophilia, but no such association exists for less differentiated tumours, This may be related to the synthesis of precursor hormones by less differentiated tumours. Mixed patterns are common, partcularly in tumours of foregut derivation. Prospective studies planned to correlate histology, histochemistry, immunocytochemistry, and ultrastructure are needed on all endocrine cell tumours.

    The MHC Class I Associated Beta2-microglobulin (β2m) Light Chain is Expressed in a Molar Excess Over HLA-ABC and CD1 on the Membrane of Leukaemic B Cells but not Leukaemic T Cells: Evidence for Further β2m-Associated Molecules (1991)

    Notes: Beta2-microglobulin (β2m) constitutes the common light chain of both the MHC-encoded HLA-ABC molecules and a group of structurally related glycoproteins recognized by antibodies of the first cluster of differentiation (CD1a, CD1b and CD1c). These CD1 antigens appear similar to murine T1 and Qa molecules in terms of structure and tissue distribution, although the question of inter-species homology is controversial. A further group of alloantigens expressed predominantly on T cells has been reported however, with immunogenetic characteristics more closely analogous to the murine T1/Qa system than the CD1 antigens, although their precise identity remains ill-defined. Having previously shown that malignant B cells may express membrane CD1c, we examined leukaemic B-cells corresponding to early lymphoblastic differentiation (null-and common acute lymphoblastic leukaemia) through to the terminal plasma cell stage for the expression of other non-HLA class I β2m -associated molecules. It was found that leukaemic B-cells at intermediate/late stages of differentiation, represented by non-Hodgkin's lymphoma (B-NHL) and‘hairy-cell’leukaemia (HCL), had significantly higher β2m: HLA-ABC ratios than did the cells from other types of B-cell malignancy. Although leukaemic B cells with a demonstrable non HLA-ABC- associated β2m component expressed detectable levels of CD1c. and insignificant levels of CD 1a and CD 1b, the antigen density was insufficient to account for the excess β2m. In vitro stimulation of leukaemic B cells by phorbol ester substantially increased the expression of HLA-ABC and CD1c, but also accentuated further the difference between the expression of these molecules and that of β2m. There was no detectable β2m other than that associated with HLA-ABC and CD1 on the surface of malignant T cells by contrast. Our findings strongly support the existence, at certain stages of leukaemic B-cell differentiation, of an additional β2m component(s) other than that associated with HLA-ABC and CD1.

    Women, work, and minor psychiatric morbidity (1979)

    Social psychiatry and psychiatric epidemiology 14 (1979), S. 53-57

    Notes: Summary The results of a community survey showed that non-married women, but not married women, had a lower rate of minor psychiatric morbidity if they were employed. It was argued that employment may protect women who lack social support in other areas. The failure to find the same results in a general practice survey suggested that women at high risk for minor psychiatric morbidity were least likely to consult a general practitioner.

    Has modern management improved the outcome of infants with intracranial tumours? (1990)

    Notes: Abstract Records of 92 children were reviewed who, in the first 18 months of life had an intracranial tumour, and who were registered with the Manchester Children's Tumour Registry during the 34-year period from 1953 to 1987. The incidence of intracranial tumour was 1 in 25000 live births, and 85% of the tumours were malignant. The introduction of computed tomography (CT) in the region in 1976 improved the diagnostic accuracy and led to early diagnosis. This also coincided with refined radiotherapy and improved chemotherapy. The surgical attitude became more aggressive, and with early treatment, mortality was reduced, though the 1-month operative mortality still remains high at 15%. All survivors were available for follow-up. All children with axial tumours died within 9 years. Long-term follow-up did not suggest significant improvement in the overall survival or in the quality of life, though there was a significant improvement in the 5-year survival rate with modern management.

    Notes: Abstract There are few population-based studies of intracranial tumours in children. This study examines 93 brain tumours in children up to 18 months of age from over 800 childhood central nervous system tumours reported to the Manchester Children's Tumour Registry during the period 1953–1987. The incidence was 1 per 25 000 live births. Of these tumours, 85% were malignant. The three most common tumours were medulloblastoma, ependymoma and juvenile astrocytoma. Eighteen percent of the tumours were in the axial region. Twenty-five percent were connected to the ventricles. The tumour was supratentorial in two-thirds of the children under 6 months of age. A high incidence of tumours in the families of these children was found; tumours were noted in two sets of siblings.

    Genetic regulation of storage protein content in maize endosperm (1976)

    Notes: Abstract Sodium dodecylsulfate-polyacrylamide gel electrophoresis reveals that zein prepared from normal maize inbred (Zea mays L.) contains six separable components. Z1 and Z2 are the predominant species, with molecular weights of 21,800 and 19,000 daltons. Amino acid analysis of these two components shows that both are rich in glutamic acid, leucine, and proline, but low in lysine. Of the four minor bands, Z3, Z4, Z5, and Z6, the latter two exist only in trace amounts. A mutation at the opaque-2 locus severely suppresses the synthesis of Z1. The nonallelic mutant, opaque-7, strongly suppresses the synthesis of Z3 and Z4, while slightly reducing Z2. On the other hand, the floury-2 mutant appears to reduce the synthesis of these six proteins in the same relative proportion. In the double mutant combinations, opaque-2 apparently is epistatic to opaque-7 and floury-2 in the synthesis of zein components. The glutelin fraction shows a more complex banding pattern; however, qualitative differences are not apparent among the mutant lines examined.
