The main objective of the study was to determine the number of growing follicles (diameter>or=4 mm) with regards to the distribution of corpora lutea (CL) on the ovaries in pregnant goats. Growing follicles with a diameter greater than 5 mm i.e. large follicles were also recorded and analyzed. Daily ultrasonography (USG) examinations of ovaries were made in six Polish White Goats starting from ...

Background: During the detorsion of a torsioned ovary, oxidant agents are released and melatonin as an antioxidant can reduce ischemia. We studied the histopathological changes after using melatonin on experimental torsioned ovary in cat. Objective: The aim of this experimental study was to investigate the effects of Melatonin on histopathological changes in torsion – detorsion injury in cat ov...

This experiment was designed to test the following two hypotheses: (1) beef cows unilaterally ovariectomized will ovulate more viable ova at the first post-operative estrus than intact animals when all are given human chorionic gonadotropin (HCG) at estrus, and that (2) this result is more likely if the CL-containing ovary is not removed. Thirty-five Angus and Anguscross cows were assigned rand...

BACKGROUND The Drosophila ovary is a tissue rich in post-transcriptional regulation of gene expression. Many of the regulatory factors are proteins identified via genetic screens. The more recent discovery of microRNAs, which in other animals and tissues appear to regulate translation of a large fraction of all mRNAs, raised the possibility that they too might act during oogenesis. However, the...

Effect of phytoecdysteroid on weight of ovary and weight of egg of multivoltine mulberry silkworm Bombyx mori was studied. Variation in the phytoecdysteroid concentration and number of larval treatment (treated the larvae) influenced the weight of ovary and weight of B. mori eggs. Experiments were performed by 40, 50, 60 and 70% concentration of phytoecdysteroid obtained from Achyranthes leaf e...

SHORT REPORTS Frequency, sequence, and side of ovulation in women menstruating normally Ovulation in the primate is usually regarded as a consistently alternating process that occurs with equal frequency in the right and left ovaries. We investigated whether ovulation in women occurs with equal frequency in each ovary, alternating consistently between the ovaries. Subjects, methods, and results...

To move closer to understanding the mechanistic underpinnings of sex differences in human longevity, we studied pet dogs to determine whether lifetime duration of ovary exposure was associated with exceptional longevity. This hypothesis was tested by collecting and analyzing lifetime medical histories, age at death, and cause of death for a cohort of canine 'centenarians'--exceptionally long-li...

BACKGROUND Women with polycystic ovary syndrome have lower pregnancy rates, possibly due to the decreased uterine receptivity. Successful implantation depends on protein networks that are essential for cross-talk between the embryo and endometrium. Apolipoprotein A1 has been proposed as a putative anti-implantation factor. In this study, we evaluated apolipoprotein A1 expression in human endome...

BACKGROUND Cryopreservation is hypothesized to result in apoptosis, contributing to stromal damage and follicle loss in ovarian tissue. This study investigated tissue viability following whole ovine ovary cryopreservation and examined the effects of the anti-apoptotic agent sphingosine-1-phosphate (S-1-P) on ovarian cryopreservation efficiency. METHODS Whole ovine ovaries were cryoperfused an...
