No. of bitstreams: 0 Previous issue date: 2005-01-01; Aim: To evaluate anti-Mullerian hormone (AMH) levels in patients with clinical and molecular diagnosis of 5 alpha-reductase 2 deficiency. Patients and Methods: Data from 14 patients whose age ranged from 21 days to 29 years were analyzed according to age and pubertal stage. Sexual ambiguity was rated as...
The influence of seasonalness on the structural characteristics of aquatic humi...
Oliveira, L. C.; Sargentini, Ézio; Rosa, André Henrique; Rocha, Júlio César; Simões, Marcelo Luiz; Martin-Neto, Ladislau; Silva, Wilson Tadeu Lopes daIn this work, humic substances were extracted from water samples collected monthly from the Negro River basin in the Amazon state (Brazil) to study their properties in the Amazonian environment and interactions with the mercury ion considering the influence of seasonalness in this formation. The C/H, C/N and C/O atomic ratio parameters, functional groups, concentration of semiquinone-type free radicals, pH, plu...
Influence of seasonality on the interaction of mercury with aquatic humic subst...
Oliveira, L. C.; Botero, Wander Gustavo; Santos, Felipe André dos; Sargentini, Ézio; Rocha, Júlio César; dos Santos, Ademir BernardoHigh mercury concentrations in different environmental matrices in the Amazon have been attributed to mining activities. However, high concentrations of mercury are also present in the soil and water in places like in the middle of the Negro River Basin, which is far away from any anthropogenic emission sources. The Amazon region is characterized by two different regional seasons, with well-defined flood and lo...
