Oxidative stress has been implicated as both a physiological cost of reproduction and a driving force on an animal's lifespan. Since increased reproductive effort is generally linked with a reduction in survival, it has been proposed that oxidative stress may influence this relationship. Support for this hypothesis is inconsistent, but this may, in part, be due to the type of tissues that have ...

The organs of the adult reproductive system can undergo extensive remodelling, experiencing rapid changes in tissue mass and function. Much of this matrix remodelling is attributed to the action of matrix metalloproteinases. Matrix metalloproteinase family members are expressed in a highly-regulated manner in many reproductive processes, including menstruation, ovulation, implantation, and uter...

Genes that are differentially expressed between the sexes (sex-biased genes) are among the fastest evolving genes in animal genomes. The majority of sex-biased expression is attributable to genes that are primarily expressed in sex-limited reproductive tissues, and these reproductive genes are often rapidly evolving because of intra- and intersexual selection pressures. Additionally, studies of...

Background: Heavy metals such as cadmium (Cd2+) are natural components of the Earth's crust which can not be degraded or destroyed. Industrial, mining and agricultural activities, particularly the excessive use of phosphate fertilizers, have led to high levels of cadmium contamination at many locations worldwide. Some toxic effects of cadmium are due to its inhibition of various enzyme sys...

Objective(s):Estrogen is a sexual hormone that has prominent effects on reproductive and non-reproductive tissues. The aim of this study is to evaluate the effects of estrogen on the proliferation and neural differentiation of human adipose derived stem cells (ADSCs) during neurogenic differentiation. Materials and Methods: Isolated human ADSCs were trans-differentiated in neural induction med...

Nanotechnology has opened a new field in medicine as well as in other sciences. The aim of this study was to seek the capability of nanotechnology for the treatment of various reproductive diseases. In this study, we analyzed all articles about “nanotechnology and reproductive medicine” published in 2000-2015, indexed in Google Scholar, PubMed and Science Direct. This study indicated that nanot...
