(Springer Link, 1990)
The following study deals with the determination of the firing temperature of some of the ceramics found in La Isabela City, Dominican Republic, first settlement of the Spaniards in the New World. These ceramics were ...
Radioisotope X-ray fluorescence analysis of vanadium in petroleum coke samples
(Journal of Radioanalytical and Nuclear Chemistry, 1990)
Radioisotope X-ray fluorescence spectrometry, RIXRF, was used for the determination of vanadium in Venezuelan petroleum coke samples using a simple standardless method and fundamental parameter approach. The values obtained ...
Glass disk fusion method for the X-ray fluorescence analysis of rocks and silicates
(Wiley Analytical Science, 1990-08)
A study of the physical and practical aspects needed for a successful solid solution method for XRF analysis is presented in the light of the theory and practice of the glass-making industry. An inexpensive manual glass ...
Male pseudohermaphroditism secondary to 5α-reductase deficiency—A model for the role of androgens in both the development of the male phenotype and the evolution of a male gender identity
(Journal of Steroid Biochemistry, 1979)
Male pseudohermaphroditism secondary to 5α-reductase deficiency is reviewed. At birth, the affected males (46 XY) have a clitoral-like phallus, bifid scrotum and urogenital sinus with the testes in the inguinal canals or ...
Hormonal evaluation of a large kindred with complete androgen insensitivity: evidence for secondary 5α-reductase deficiency.

(Experimental and Molecular Pathology, 1979-08)
We have studied 450 cases of human breast carcinoma at the histochemical and ultrastructural level. The breast biopsies were obtained from Canada, Mexico and Dominican Republic.This study was undertaken to evaluate the ...
Urinary steroid metabolites in subjects with male pseudohermaphroditism due to 5α-reductase deficiency
(Wiley, 1985-07)
To investigate the enzymatic basis for abnormal steroid metabolism in subjects with male pseudohermaphroditism due to 5α-reductase deficiency, the ring A reduced urinary 5β and 5α metabolites of testosterone, androstenedione, ...
Androgens and the evolution of male-gender identity among male pseudohermaphrodites with 5alpha-reductase deficiency.
(New England Journal of Medicine, 1979-05-19)
To determine the contribution of androgens to the formation of male-gender identity, we studied male pseudohermaphrodites who had decreased dihydrotestosterone production due to 5 alpha-reductase deficiency. These subjects ...
