background and objective: it is well known that menstrual period and ovarian function are affected by chemotherapy. although breast cancer is the most common cause of chemotherapy in women and ovarian hormones have very important direct and indirect effects on overall survival, disease-free survival, and life quality of patients, but few studies have addressed the frequency and related factors ...

When treating infertile couples by assisted reproductive technologies (ART), all aspects of their care in individual clinics should be evaluated frequently. Results should then be compared with other clinics offering similar treatment. Evaluation of possible adverse longterm outcomes can be achieved by pooling results from individual clinics in national, regional and international registers and...

The vascular endothelial growth factor (VEGF) gene single-nucleotide polymorphism involved in the regulation of the protein levels has been implicated in breast cancer. However, the published studies have produced contentious and controversial results. Herein, we performed a meta-analysis (from January to October 2013); to further evaluate the association between +936 C/T polymorphism and the r...

Background: Breast cancer is the malignancy in humans and other mammals. Several risk factors are involved in their appearance such as higher hormone levels and obesity. Identification of a mouse mammary tumor virus supports a viral etiology for breast tumors in animals. Viruses have been implicated in the development of various cancers, but viral induction for formation breast cancer is contro...

Glutathione S-transferases (GSTs) are encoded by a superfamily of genes and play a role in the detoxification of potential carcinogens. The human GSTs are divided into four classes: alpha, mu, pi and theta. Previous studies indicated that the absence of the Glutathione S-Transferase M1 (GSTM1) protein correlated with an increased risk of developing some types of cancers. Association between spe...
