Ultrastructure of the ovary of Dermatobia hominis (Diptera: cuterebridae). I. Development during the 3rd larval instar
(Instituto Oswaldo Cruz, Ministério da Saúde, 1990-09-01)
The ultrastructure and distribution of gonial and somatic cells in the ovary of Dermatobia hominis was studied during the 3rd larval instar. In larvae weighing between 400 and 500 mg, the ovary is partially divided into ...
Distribution of Rickettsia rickettsii in ovary cells of Rhipicephalus sanguineus (Latreille1806) (Acari: Ixodidae)
(Biomed Central Ltd., 2011-11-25)
Background: Considering the fact that the dog tick, Rhipicephalus sanguineus, has a great potential to become the vector of Brazilian Spotted Fever (BSF) for humans, the present study aimed to describe the distribution of ...

STRUCTURAL AND ULTRASTRUCTURAL ANALYSIS OF GERM CELLS FROM OVARIES OF FETUSES OF BUFFALOES
(Pakistan Agricultural Scientists Forum, 2012-01-01)
The objective of this research was the structural and ultra structural characterization of the oogonia, primary oocytes and preantral follicles of buffalo foetuses at different gestational stages. For this study twenty-nine ...
In vivo β-adrenergic blockade by propranolol prevents isoproterenol-induced polycystic ovary in adult rats
(2012)
Increasing evidence in animal models and in humans shows that sympathetic nerve activity controls ovarian androgen biosynthesis and follicular development. Thus, sympathetic nerve activity participates in the follicular ...
Ovarian growth during larval development of queen and worker of Apis mellifera (Hymenoptera: Apidae): a morphometric and histological study.
(2003-02-01)
The present work reports the differences between the ovarian grow in queen and worker larvae of A. mellifera, from the start of differential feeding. The observations made of the growth rates in larvae of both castes showed ...
