    Circulating TNF-α, TGF-β, and IL-10 in Tuberculosis Patients and Healthy Contacts (2001)

    Notes: Levels of tumour necrosis factor (TNF)-α, transforming growth factor (TGF)-β, and interleukin (IL)-10 in plasma of pulmonary tuberculosis (TB) patients and healthy contacts and plasma and pleural fluid of patients with tuberculous pleuritis were examined by enzyme immunoassay. Plasma TNF-α and IL-10 were elevated to significant levels in healthy contacts. High levels of TGF-β and IL-10 were also detected in plasma from TB patients and healthy contacts. Pleural fluid contained all three cytokines with the level of IL-10 being highest followed by TGF-β and TNF-α. Plasma of tuberculous pleuritis patients also had detectable levels of the three cytokines. Increased levels of TNF-α in plasma of contacts and to some extent pleural fluid of pleuritis patients, is perhaps to limit the infection, while elevated IL-10 in plasma of TB patients and contacts and pleural fluid would perhaps modulate excess proinflammation. Elevated TGF-β in TB patients suggests its role in the immunopathogenesis.

    The distinctness and diversity of Ethiopian barleys (1997)
    Springer
    Theoretical and applied genetics 94 (1997), S. 514-521

    ISSN: 1432-2242

    Notes: Abstract  The relative diversity and distinctness of Ethiopian barleys has been investigated using (1) morphology/isozyme/hordein polymorphisms and (2) RFLP markers. In the former a set of 51 landraces from over the whole of Ethiopia was compared with Iranian landraces based on data from previous studies and new hordein data. The two sets of landraces were found to have a comparable diversity. The Ethiopian ones are more diverse morphologically (5 traits), are similar in numbers of alleles per protein locus (17 loci) and in genetic differentiation, but are less diverse in average heterozygosity per locus and degree of polymorphism. However, on the basis of the hordein data the two sources of germplasm are very distinct. The correlation between morphological and protein diversity is very low. In the RFLP study 28 probes evenly distributed across the genome were used to analyse 43 Ethiopian landraces (represented by one single genotype) and to compare them with modern cultivars from North America, Europe and Japan, as well as 3 landraces from Iran, 1 from Nepal, and 1 accession of H. spontaneum from Afghanistan. The major finding was that the Ethiopian germplasm appears to be significantly less diverse than the modern germplasm but that it is genotypically very distinct. The apparent contradiction between a high diversity of useful genes coming from Ethiopia and an apparently low diversity at the DNA level is discussed.

    Genetic characterization of Lens ervoides from Ethiopia (1992)

    Notes: Summary A single population of the Mediterranean species Lens ervoides was located in Ethiopia and seeds were collected. Based on chromosomal arrangement and isozyme profile the Ethiopian L. ervoides is similar to populations of this species in the Mediterranean region. All hybrids between L. ervoides from Ethiopia and an accession of this species from Israel were dwarf, whereas hybrids between the former and an accession from Algeria were normal. Segregation in F2 and BC generations indicated that the dwarf habit in lentil is governed by dominant alleles of two complementary genes designated df 1 and df 2. The dominant allele of another gene, dfi, inhibits the dwarf phenotype. The evolution of L. ervoides from Ethiopia and its potential as a genetic resource are briefly discussed.
