[ 1 ] - Reactive oxygen species level, mitochondrial transcription factor A gene expression and succinate dehydrogenase activity in metaphase II oocytes derived from in vitro cultured vitrified mouse ovaries

The aim of this study was to evaluate the effects of ovarian tissue vitrification and two-step in vitro culture on the metaphase II (MII) oocyte reactive oxygen species (ROS) level, mitochondrial transcription factor A (TFAM) expression and succinate dehydrogenase (SDH) activity. After collection of neonatal mouse ovaries, 45 ovaries were vitrified and the others (n = 45) were...

[ 2 ] - Effect of lysophosphatidic acid on the follicular development and the ‎expression of lysophosphatidic acid receptor genes during in vitro culture of ‎mouse ovary

Lysophosphatidic acid (LPA) known as a serum-derived growth factor, is involved in several cell physiological functions in the female reproductive system including: oocyte maturation, in vitro fertilization and embryo implantation by its transmembrane G protein-coupled receptors. The aim of the present study was to examine the effect of LPA on in vitro follicular development o...

[ 3 ] - اثرات سمی بخارات فرمالدئید بربافت بیضه و پارامترهای اسپرم موش سوری بالغ

  Background and aim: Formaldehyde ( H2C = O ) ,is a member of aldehyde family with the simplest organic molecules ,used in various industries. The aim of this experimental study was to investigate the detrimental effects of formaldehyde on testicular tissue and sperm quality in mice.   Methods : Thirty six mature male NMRI mice were randomly divided into three equal groups (n=12). Group F1 (lo...

[ 4 ] - مروری بر فعالیت عوامل رگزایی و مرگ سلولی در بافت تخمدان پیوندی

Many changes of female reproductive system are based on the vascular activity and blood flow. In ovarian follicular development, re-anastomosis is critical and permits cells and oocytes to utilize nutrients as well as the hormones. Moreover, it plays a main role in corpus luteum formation. Female reproductive system undergoes several angiogenesis programs which are considered essential in order...

[ 5 ] - Ovarian Stimulation by Exogenous Gonadotropin Decreases the Implantation Rate and Expression of Mouse Blastocysts Integrins

Background: Integrins are heterodimeric glycoprotein receptors that regulate the interaction of cells with extracellular matrix and may have a critical role in implantation. The aim of this study was to investigate the effect of ovulation induction on the expression of α4, αv, β1, and β3 integrins in mouse blastocyst at the time of implantation. Methods: The ovarian stimulated and non-stimulate...

[ 6 ] - Human Ovarian Tissue Vitrification/Warming Has Minor Effect on the Expression of Apoptosis-Related Genes

Background: In this study, we evaluated the incidence of apoptosis at the ultrastructural levels and expression of some apoptosis-related genes in vitrified human ovarian tissue just after warming. Methods: Human ovarian tissue biopsies from 23 women after caesarean section were transported to the laboratory within 2 hours, and then they were cut into small pieces. Some pieces were vitrified an...

[ 7 ] - The Effect of Vitrification and in vitro Culture on the Adenosine Triphosphate Content and Mitochondrial Distribution of Mouse Pre-Implantation Embryos

Background: The mitochondria are an important source of adenosine triphosphate (ATP) production in pre-implantation embryo. Therefore, the objective of this study was to investigate the effect of vitrification and in vitro culture of mouse embryos on their mitochondrial distribution and ATP content. Methods: The embryos at 2-PN, 4-cell and blastocyst stages were collected from the oviduct of st...

[ 8 ] - The Correlation between the Endometrial Integrins and Osteopontin Expression with Pinopodes Development in Ovariectomized Mice in Response to Exogenous Steroids Hormones

Background: The ovariectomized animals are good models to evaluate the effect of different steroid hormone treatments on implantation events and the pattern of integrin expression. Therefore, this study was performed to compare the expression of integrins and osteopontin (OPN) in correlation with pinopode development in ovariectomized mice endometrium which was subjected to steroid hormones. Me...

[ 9 ] - Morphometric Analysis of Offspring Ovary in Mice Following Oxaliplatin Treatment during Perinatal Period Using Stereology Technique

  Background & objectives: Oxaliplatin is a third-generation of platinum drug which is the main therapeutic agent for the treatment of colorectal cancer. Oxaliplatin not only inhibits DNA replication but also transcription and also induces apoptosis or necrosis in cancer cells and rapidly dividing cell lines. Although it is widely used clinically, there is no enough information regarding its ef...
