Abstract
Background: Significant economic consequences can lead to various problems and complications, including medical complications. Coronary artery disease (CAD), a serious health threat with increasing prevalence, is a major cause of death and mortality worldwide. This study aimed to investigate the effects of a special training program on cytochrome P450 (CYP) gene expression and reactive oxygen species (ROS) levels in patients with coronary artery bypass surgery.
Methods: This semi-experimental study was conducted on 16 patients who underwent coronary artery surgery in Babol City, Iran. The patients were selected using a random sampling method and divided into 2 groups: experimental and control groups. The experimental group engaged in an exercise program consisting of 3 sessions per week for a duration of 8 weeks. The expression levels of CYP and ROS genes were measured by the real-time polymerase chain reaction (PCR) method. The analysis was performed by comparing covariances and means.
Results: ROS gene expression levels significantly decreased in the experimental group than in the control group (P=0.003). However, there was no significant difference in P450 levels between the experimental and control groups (P=0.99).
Conclusion: Special exercises reduced ROS expression and increased P450 expression in patients who had coronary bypass surgery. There is a probability that special exercises, can effectively prevent heart damage by increasing antioxidant capacity and reducing ROS.

Abstract
Background: Diabetes mellitus (DM) is a metabolic disease characterized by hyperglycemia, disturbed lipid metabolism, and cardiovascular disease (CVD). Poor glycemic control results in lipid and lipoprotein abnormalities, suggesting that dyslipidemia is secondary to insulin resistance or factors closely related to insulin resistance. Glaciated hemoglobin (HbA1c) is a routinely used marker for long-term glycemic control. This form of hemoglobin is chemically processed through post-translational glycosylation that reflects the plasma glucose concentration during the last two to three months.
Methods: This cross-sectional study was conducted on blood samples from 592 cases referred to Dezyani Specialty Clinic, affiliated with the Golestan University of Medical Sciences. In patients with diabetes mellitus (DM) and non-diabetic individuals, hemoglobin A1c (HbA1c), total cholesterol (T-chol), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were measured.
Results: In the study, there were 460 female participants (76.9%) and 132 male participants (23.1%). Among them, 403 (67.4%) were diabetic patients, and 193 (32.4%) were non-diabetic. HbA1c levels were significantly lower in younger individuals than in middle-aged participants (p=0.000). No significant difference was found between middle-aged and older individuals (p>0.121). LDL levels were significantly lower in the young group than in the middle-aged group (p<0.001). Total cholesterol (TC) was also significantly lower in the young group compared to middle-aged and older groups (p<0.001).
Conclusion: HbA1c can be a helpful lipid and glycemic control marker in diabetes.
