Indirect coculture of stem cells with fetal chondrons using PCL electrospun nanofiber scaffolds.

In vitro coculture system provides a powerful tool for tissue engineering. In this study, we evaluated the gene expressions of human adipose-derived stem cells (ASCs) on polycaprolactone (PCL) scaffold in coculture model with fetal chondrons. Electrospun PCL scaffolds (900 nm fiber diameter) were created and human infrapatellar fat pad-adipose-derived stem cells (IPFP-ASCs) were seeded on these scaffolds.

Evaluation of the melatonin and oxidative stress markers level in serum of fertile and infertile women.

Background: Infertility is defined as the inability to achieve the pregnancy within a year of unprotected intercourse. Infertility is a complex issue and different factors such as stress oxidative can be involved in this problem. So, any attempt to neutralize oxidative stress would be helpful in the treatment of infertility.

The effect of BSO-induced oxidative stress on histologic feature of testis: testosterone secretion and semen parameters in mice.

Objectives: Buthionine sulfoximine (BSO) inhibits synthesis of glutathione as the main intracellular antioxidant. The aim of the present study is to investigate the effect of BSO-induced oxidative stress on histological structure of testis, testosterone secretion and semen parameters.

Materials And Methods: Thirty male BALB/c mice were divided into 3 groups.

Serum Levels of Melatonin and Oxidative Stress Markers and Correlation between Them in Infertile Men.

Introduction: Infertility is the problem of 15% of young couples in different societies. One of the factors that could affect fertility is oxidative stress. Therefore, the aim of the present study is to investigate the level of Melatonin, a free radical scavenger, and its correlation with oxidative biomarkers in infertile men.

Study of ultrastructure and apoptosis in the endometrium of women with or without endometriosis.

Background: More than 40% of infertilities are due to endometriosis. Ultrustructural and histochemical study of endometrium will help to clarify the etiology of endometriosis.

Objective: The aim of the present study was to investigate the ultrastructure and occurrence of apoptosis in endometrial cells of women with or without endometriosis.

Ultrastructural and morphometrical study of preimplantation endometrium in superovulated mice treated with progesterone or Sildenafil.

Background: Endometrial development has an important role in blastocyst adhesion and implantation. During IVF cycles, endometrial development is enhanced by progesterone.

Objective: The aim of this study was to compare ultrastructural and morphometrical characteristics of mice uterine endometrium in natural cycle with those in superovulated cycles received progesterone or Sildenafil.
