Inflammatory disorders account for a significant percentage of gynecologic diseases, particularly in women of reproductive age. It is known that stem cells have anti-inflammatory and regenerative properties. Based on this, we investigated the effect of intravenous administration of cryopreserved mesenchymal stem cells (cMSCs) of bone marrow on experimental chronic inflammation of the ovaries. T...

in this study we investigated histopathological changes of mice ovarian tissues following long-term administration of copper sulfate and induction of chronic copper poisoning. the study comprised of three different groups of twenty one mice as follows: the first group (group 100) which treated by gavage with copper sulfate at a dose of 100 mg kg-1 for 5 weeks. the second group (group 200), whic...

BACKGROUND A decline in fertility is evident in human females past their middle thirties. This 'reproductive senescence', marked by a sharp decline in pregnancy rates, may be attributed to reductions in numbers of available oocytes and their quality. Because Old World primates exhibit ovarian morphology and physiological control and timing of menstrual cycles closely resembling those of humans,...

Seyed Mohammad Ali Shariatzadeh & Zahra Alizadeh Department of Biology, Faculty of Sciences, Arak University, Arak, Iran Correspondent author: Seyed Mohammad Ali Shariatzadeh, [email protected] Abstract. Silver nanoparticles (Ag NPs) can affect female fertility because they can cause toxicity in the ovaries. The aim of this study is to see if Spirulina platensis (SP) can protect m...

There is accumulating evidence that local renin-angiotensin systems (RASs) influence cell growth and organ function in a variety of tissues including the ovary. The first aim of this study was to characterise the cellular location of RAS components in the rat ovary. This was facilitated by the use of the hypertensive transgenic (mRen-2)27 rat which overexpresses renin and angiotensin in extra-r...

An attempt was made to describe the updated information about the factors to be concerned before using of buffalo follicular fluid for supplementation in vitro of buffalo oocyte. There are not only diameter of the follicle, the present of corpus luteum (CL), growth of follicles, stage of estrus cycle, healthy and atretic state of the ovarian follicles. The progesterone and estradiol-17B concent...

Granulosa cell death is an early feature of atresia; however, there are many apparent contradictions in the literature concerning the mode of granulosa cell death. We have therefore examined this process in bovine healthy and atretic antral follicles, using a variety of established techniques. Light and electron microscopic observations indicated the presence of pyknotic or shrunken nuclei in b...
