Effect of narcosis with CO2 on the ovarian development in queens of Apis mellifera (Hymenoptera, Apini)
(California State University, 2005-01-01)
Exposure of 1, 4, 7 & 10 day-old virgin queens of Apis mellifera Linne 1758 for 1 min to CO2 accelerated their ovarian development, having a similar effect as mating on the initial formation of the ovarian follicles. In 3 ...
Effects of in vitro exposure to butylparaben and di-(2 ethylhexyl) phthalate, alone or in combination, on ovarian function
(2016-09-01)
Parabens and phthalates are commercial chemicals widely used in the manufacture of industrial and consumer products frequently found as contaminants in biological fluids. We evaluated the effects of di-(2-ethylhexyl) ...
Effects of atrazine on female Wistar rats: Morphological alterations in ovarian follicles and immunocytochemical labeling of 90 kDa heat shock protein
(2008-07-01)
Fertility in female mammals may be affected by a variety of endocrine disrupters present in the environment. Herbicide atrazine is an example of endocrine disrupter employed in agriculture, which disrupts estrous cyclicity ...
Effect of anti-apoptotic drug Z-VAD-FMK on in vitro viability of dog follicles
(2018-12-01)
It is recognized that ovarian follicular atresia is associated with apoptosis, and the most important effector of cell death is caspase-3. The aim of this study was to investigate the influence of anti-apoptotic drug ...
Specific protocols of controlled ovarian stimulation for oocyte cryopreservation in breast cancer patients
(2018-12-01)
Background Fertility preservation is an important concern in breast cancer patients. In the present investigation, we set out to create a specific protocol of controlled ovarian stimulation (cos) for oocyte cryopreservation ...
Effect of follicle age on conception rate in beef heifers
(Amer Soc Animal Science, 2014-03-01)
The objective of this study was to determine the effect of age of the ovulatory follicle on fertility in beef heifers. Ovulation was synchronized with the 5 d CO-Synch + controlled intravaginal drug release (CIDR) program ...
Scavenger receptor-B1 and luteal function in mice
(New York, 2010)
During luteinization, circulating high-density lipoproteins supply cholesterol to ovarian cells via the scavenger receptor-B1 (SCARB1). In the mouse, SCARB1 is expressed in cytoplasm and periphery of theca, granulosa, and ...
Ovarian nutritional resources during the reproductive cycle of the hematophagous Dipetalogaster maxima (Hemiptera: Reduviidae): focus on lipid metabolism
(Wiley-liss, Div John Wiley & Sons Inc, 2014-11)
In this study, we have analyzed the changes of the ovarian nutritional resources in Dipetalogaster maxima at representative days of the reproductive cycle: previtellogenesis, vitellogenesis, as well as fasting-induced early ...
Regulation of ovarian angiogenesis and apoptosis by GnRH-analogs
(Wiley, 2008)
An adequate vascular supply is important to provide endocrine and paracrine signals during follicular development. We evaluated the direct in vivo effects of both the GnRH-agonist Leuprolide acetate (LA) and the GnRH-antagonist ...
Immunolocalization and effect of low concentrations of Insulin like growth factor-1 (IGF-1) in the canine ovary
(Wiley-Blackwell, 2020-09-07)
Insulin like growth factor-1 (IGF-1) plays an important role in the regulation of ovarian function. Despite its extensive study in several species, there is a paucity of information about IGF-1`s function and localization ...
