Hp, Gc, Cp, Tf, Bg and Pi phenotypes in leprosy patients and healthy controls from West Bengal (India)

1972

On a sample of n=601 leprous individuals and n=386 healthy controls from West Bengal (India) the question is discussed, if there are existing any associations between leprosy and several serum protein groups like haptoglobin, Gc, ceruloplasmin, transferrin, β2 I and Pi. No associations were found concerning the haptoglobins and transferrins. Certain associations came out respecting ceruloplasmin, β2 I and Pi phenotypes. However, these associations, which were found in connection with the different types and clinical courses of leprosy, should be reexamined by further research. The most striking results were obtained concerning the Gc proteins. In accordance with previously performed investi…

Age and tectonic setting of granitoid gneisses in the Eastern Desert of Egypt and south-west Sinai

1994

Strongly deformed and locally migmatized gneisses occur at several places in the southern Eastern Desert of Egypt and in Sinai and have variously been interpreted as a basement to Pan-african (≈900 to 600 Ma) supracrustal and intrusive assemblages. A suite of grabbroic to granitic gneisses was investigated in the Hafafit area, which constitutes an I-type calc-alkaline intrusive assemblage whose chemistry suggests emplacement along an active continental margin and whose granitoid members can be correlated with the so-called ‘Older Granites’ of Egypt. 207Pb/206Pb single zircon evaporation from three samples of the Hafafit gneisses yielded protolith emplacement ages between 677 ± 9 and 700 ± 1…
