Abstract
ABSTRACT
Breast cancer remains the most common cancer of women and one of the most common causes of cancer-related deaths worldwide. In spite of major advances in breast cancer diagnosis and treatment, the incidence of breast cancer remains high and the treatment of metastatic breast cancer remains challenging. This review presents an overview of breast cancer with a particular focus on its clinical aspects and therapies.
Keywords: Breast Cancer, Risk Factors, Diagnosis, Treatment.

Abstract
Background and objectives: Osteoarthritis is one of the most common arthritic diseases and a main cause of pain and disability. Simultaneous downexpression of paired box 7 (Pax7) and myogenin genes, as indicators of satellite cells activation is evident in osteoarthritis. This study assessed effects of an exercise training course and stem cell injection on the expression of Pax7 and myogenin in gastrocnemius muscle of rats with arthritis.
Methods: Thirty five male rats aged 6–8 weeks and weighing 250–300 g were divided into five groups: control, patient, exercise, mesenchymal stem cell (MSC), and exercise+MSC. Osteoarthritis was induced in rats by surgery. The training program consisted of 30 minutes of running on a non-slip treadmill at a speed of 16 m/min. The rats were injected with 1×106 cells/kg MSC. The expression of Pax7 and myogenin was measured by real–time PCR. Data were analysed with SPSS (version 23) using one-way analysis of variance.
Results: Both Pax7 and myogenin were significantly overexpressed in the exercise+MSC group compared to the patient group (P<0.001).
Conclusion: The combination of MSC therapy and training had more positive effects on Pax7 and myogenin expression compared to training and MSC therapy alone.

Abstract
Background and objectives: Sedentary life style and high-fat diet are one of the key causes of coronary artery disease. The aim of this study was to evaluate effects of periodic exercise and consumption of fenugreek seed extract on the expression of oxidized low-density lipoprotein (oxLDL) and reactive oxygen species (ROS) genes in patients with coronary artery occlusion.
Methods: The present quasi-experimental study was performed on 32 men (60±5 years) with coronary artery disease. The subjects were randomly divided into four groups: control, exercise, fenugreek supplementation, and combination of exercise and fenugreek supplementation. The training program consisted of eight weeks of intermittent running at 55 to 65% heart rate reserve, three sessions per week, with an emphasis on gradual overload. The subjects consumed 10 mg/kg of body weight fenugreek extract daily. Data analysis was performed using two-way analysis of variance and Tukey's test at statistical significance of 0.05.
Results: The mean expression ratio of oxLDL and ROS genes in the intervention groups decreased significantly (p<0.0001). Compared with the control group, the most profound decreased in oxLDL and ROS expression occurred after combination of exercise and fenugreek supplementation (p<0.0001).
Conclusion: The results showed that intermittent exercise and consumption of fenugreek seed extract might have beneficial effects on the antioxidant defense system in patients with coronary artery occlusion.

Abstract
Background and objectives: Endometriosis is a chronic disease that affects approximately 10% of women of reproductive age. The purpose of this study was to evaluate the effects of 8 weeks of swimming exercise and omega-3 supplementation on the expression of cyclooxygenase-2 (COX-2) and prostaglandin E2 (PGE2) genes and serum levels of reproductive hormones in the endometrial tissue of a rat model of endometriosis.
Methods: In this experimental study, 30 adult Wistar rats were randomly divided into 5 groups of healthy-control, patient-control, patient+exercise, patient+omega-3, and patient+omega-3+exercise groups. After the induction of endometriosis, the rats were subjected to 8 weeks of swimming exercise, 5 days a week as well as 2 ml/kg/body weight of omega-3. Data were analyzed using one-way analysis of variance and Tukey post hoc test at the significance level of 0.05.
Results: The expression of COX-2 and PGE2 as well as serum follicle-stimulating hormone (FSH), luteinizing hormone (LH), and estradiol levels were significantly higher in the patient group compared with the healthy-control group (p≤0.0001). Exercise and omega-3 supplementation either separately or combined could significantly reduce the expression of both genes and serum levels of LH, FSH, and estradiol (p<0.05). This effect was more profound in the patient+exercise+omega-3 group.
Conclusion: The results of the present study indicate that regulating the expression of COX-2 and PGE2 genes as well as serum levels of reproductive hormones through swimming exercise and omega-3 supplementation can improve endometriosis.
