Histochemical studies of Rhinocricus padbergi Verhoeff ovaries (Diplopoda, Spirobolida, Rhinocricidae)
(Faculty Press, 1998-01-01)
Histochemical studies of Rhinocricus padbergi Verhoeff ovaries demonstrated that the oocytes contained lipids, proteins and polysaccharides. The probable synthesis site of each is considered, and the origin and function ...
Fat body, hemolymph and ovary routes for delivery of substances to ovary in Melipona quadrifasciata anthidioides: Differences among castes through the use of electron-opaque tracers
(2013-08-01)
The yolk protein precursor, vitellogenin (Vg), in bees is synthesized in the fat body trophocytes, delivered to the hemolymph and ultimately absorbed from there during the vitellogenic phase of oocytes in the active ovary. ...
Role of RFRP-3 in the development of cold stress-induced polycystic ovary phenotype in rats
(NLM (Medline), 2018)
2018 Society for Endocrinology RFamide-related peptide (RFRP-3) is a regulator of GnRH secretion from the brain, but it can also act in human ovary to influence steroidogenesis. We aimed to study the putative local role ...
Apis mellifera (Hymenoptera, Apini) Ovary Development in Queens and in Workers from Queenright and Queenless Colonies
(2003-12-08)
A morphological study of the development of the ovaries in workers from queenright and queenless colonies and queens of Apis mellifera is presented and discussed. The mating stimulates the ovary development and the egg-laying. ...
Development of worker ovaries in Brazilian Africanized honeybees (Hymenoptera: Apidae)
(2004-11-23)
The present paper compares the worker ovaries development in queen right and orphaned colonies of Brazilian Africanized honeybee. The results show that in both colonies some workers starting 20 days after emergence, present ...
Ovary and oocyte maturation of the tick Amblyomma brasiliense Aragao, 1908 (Acari: Ixodidae)
(Pergamon-Elsevier B.V. Ltd, 2010-01-01)
This study describes the ovary anatomy and dynamics of oocytes maturation process of Amblyomma brasiliense ticks. The ovary is of panoistic type lacking nurse and follicular cells. This organ consists of a single continuous ...
Morphological characterization of the ovary and oocytes vitellogenesis of the tick Rhipicephalus sanguineus (Latreille, 1806) (Acari : Ixodidae)
(Elsevier B.V., 2005-06-01)
This study presents the morphology of the ovary, as well as the process of the vitellogenesis in oocytes of the tick Rhipicephalus sanguineus. The ovary of these individuals is of the panoistic type; therefore, it lacks ...
Histological assessment of ovaries and uterus of rats subjected to nandrolone decanoate treatment
(Elsevier B.V., 2005-07-01)
This study aimed to analyze the effects of nandrolone decanoate on the ovaries and uterus of adult females rats. This drug was administered intraperitoneally, at one, two and three doses of 3 mg nandrolone decanoate/kg of ...
Differential morphology of the hemocytes present in pupal ovaries of the queen and worker honeybee
(2001-12-01)
The location and morphological features of the blood cells found in the pupal ovary of workers and queens of Apis mellifera are described in relationship with their probable function in the ovary differentiation. The ...
Effect of mating delay in the ovary of Apis mellifera L. (Hymenoptera, Apidae) queens: Histological aspects
(2007-11-30)
This paper reports the effect of mating delay on the queen Apis mellifera ovaries based on a light microscopy analysis. Soon after a queen emerges from the brood cell, oocytes start to differentiate in the ovaries, but if ...
