Ultrastructural analysis of the nucleolar aspects at spermiogenesis in triatomines (Heteroptera, Triatominae)
(Pergamon-Elsevier B.V. Ltd, 2010-10-01)
In this study the ultrastructural technique was used to analyze seminiferous tubule cells of the triatomine species Panstrongylus megistus, Rhodnius pallescens and Triatoma infestans. The data obtained provided evidence ...
Ultrastructure of ovarian follicular epithelium of the amazonian fish Pseudotylosurus microps (Gunther) (Teleostei, Belonidae): I. the follicular cells cycle of development
(Sociedade Brasileira de Zoologia, 2001-03)
The present paper deals with the changes on ultrastructural features of the follicular cells along the growth of the oocyte of Pseudotylosurus microps (Gunther, 1868). The epithelium pass from single squamous to pseudostratified ...
Ultrastructural alterations in colon absorptive cells of alloxan-induced diabetic rats submitted to long-term physical training
(Wiley-Blackwell, 2012-10-01)
Absorptive cells have notable importance for proper function of the colon, absorbing water and nutrients. In type I diabetes, hyperglycemia leads to remarkable alterations in cell structure. In absorptive cells, such changes ...

Antileishmanial activity and ultrastructural changes of sesquiterpene lactones isolated from Calea pinnatifida (Asteraceae)
(2019-03-01)
Bioactivity-guided fractionation of antileishmanial active CH 2 Cl 2 phase of MeOH extract from leaves of Calea pinnatifida led to isolation of two sesquiterpene lactones calein C (1) and calealactone C (2), which structures ...
