Performance of the parallel plate avalanche counter (PPAC) for improving the depth profile of conversion electron Mössbauer spectroscopy (CEMS)
(Journal of Radioanalytical and Nuclear Chemistry, 1991)
The parallel plate avalanche counter (PPAC) built in our laboratory was used to measure the CEM spectra of iron electrodeposited over a steel substrate. The electron counter was operated with ketone gas inside the ionization ...
Extraction of vanadium from petroleum coke samples by means of microwave wet acid digestion
(Elsevier, 1990-01)
Certified coal standards and Venezuelan petroleum coke samples were submitted to microwave acid digestion to evaluate the convenience of this procedure for the extraction of their vanadium content. The solution and the ...
Inherited 5α-reductase deficiency in man
(ScienceDirect, 1986)
Study of the syndrome of 5α-reductase deficiency in man has elucidated the importance of testosterone conversion to dihydrotestosterone in sexual differentiation of the male fetus. Insights into specific actions for ...

The biochemical and phenotypic characterization of females homozygous for 5 alpha-reductase-2 deficiency
(The Journal of Clinical Endocrinology & Metabolism,, 1995-11)
The biochemical and physiologic manifestations of decreased 5 alpha-dihydrotestosterone (DHT) in females are characterized. Three females from the large Dominican kindred with 5 alpha-reductase-2 deficiency were identified ...
Prostate visualization studies in males homozygous and heterozygous for 5 alpha-reductase deficiency
(The Journal of Clinical Endocrinology & Metabolism, 1992-10-01)
Male pseudohermaphrodites with 5 alpha-reductase deficiency have ambiguous genitalia and nonpalpable prostates on rectal examination, suggesting the dihydrotestosterone dependency of these structures. To clearly delineate ...
Current status and challenges of stem cell treatment for Alzheimer’s disease
(Journal of Alzheimer’s Disease, 2021)
Neurodegenerative diseases called tauopathies, such as Alzheimer’s disease (AD), frontotemporal dementia, progressive supranuclear palsy, and Parkinson’s disease, among others, are characterized by the pathological processing ...
Luteinizing hormone pulsatility in subjects with 5-alpha-reductase deficiency and decreased dihydrotestosterone production
(PulbMed, 1994-04)
The pattern of LH pulsatility in male pseudohermaphrodites with inherited 5 alpha-reductase-2 deficiency (5 alpha RD) and decreased levels of plasma dihydrotestosterone was compared to that in normal males. Analysis of ...
