Abstract
Background: Physical activity combined with mineral supplementation has been reported to enhance bone mineral density and improve bone health after menopause. Accordingly, the present study aimed to investigate the effects of BodyPump training in combination with calcium and vitamin D supplementation on bone health biomarkers in postmenopausal women.
Methods: In this quasi-experimental study with a pretest-posttest placebo-controlled design, 45 postmenopausal women from Isfahan, aged 55-65 years with a body mass index (BMI) of 24±3 kg/m², were purposively selected and randomly assigned to three groups: BodyPump training, BodyPump training plus calcium and vitamin D supplementation, and placebo. The exercise protocol was conducted for eight weeks, three sessions per week, lasting 40-60 minutes per session with 10% One-Repetition Maximum. In addition, participants in the BodyPump+supplementation group consumed two calcium+vitamin D tablets daily for eight weeks. Data were analyzed using multivariate analysis of covariance (MANCOVA) followed by Bonferroni post hoc tests.
Results: A significant increase in bone-specific alkaline phosphatase (BSAP) was observed in both the BodyPump and BodyPump+supplementation groups (p≤0.001). Moreover, a significant reduction in the C-terminal telopeptide of type I collagen (CTX) was found in both intervention groups (p≤0.002). Notably, the changes in these biomarkers were significantly greater in the BodyPump+ calcium and vitamin D supplementation group compared to exercise alone.
Conclusion: These findings suggest that BodyPump training combined with calcium and vitamin D supplementation has beneficial effects on bone health biomarkers in postmenopausal women. Therefore, the combined use of exercise and supplementation may be a valuable strategy to improve bone health outcomes in this population.

Abstract
Background & Objectives: Different studies have reported conflicting results on increased rate of early mortality after acute myocardial infarction (AMI) in females compared to males after adjustment for age and other confounding factors. The female gender plays a crucial role in early mortality after AMI. The aim of this study was to assess the role of gender as an important key factor in early mortality after acute myocardial infarction. Methods: In this research, patients (80 females and 174 males) with acute myocardial infarction were studies for six months (2003-2004) in terms of risk factors of coronary artery diseases, clinical conditions at admission, treatment modalities in the hospital and at the time of discharge, clinical accidents at the hospital and mortality and during one month after acute myocardial infarction and after being discharged. Results: Intrahospital mortality odds ratio for females compared to males was 2 (confidence interval 95%: 0.951-4.208). Mortality odds ratio during one month after acute myocardial infarction and discharge for females compared to males was 4.586 (confidence interval 95%: 1.294-16.252). This rate after adjustment for age was 3.15 (confidence interval 95%: 0.857-11.579) and after adjustment for confounders was 5.387 (confidence interval 95%: 1.296-22.393). In severe clinical conditions females referred to hospitals with more delay compared to men. Females were treated less than males with streptokinase, aspirin, betablockers and invasive diagnostic and treatment procedures. They received calcium channel blockers and nitrate much more than males. Conclusions : Females in comparison with males were at higher risk for early mortality (during one month after acute myocardial infarction and discharge). Age was not considered as the most important and potential factor for this higher rate.

Abstract
Background & Objectives: Urinary stone disease is one of the common urinary tract complications that can lead to renal failure. It occurs usually in middle-aged and older men The aim of this study was to determine the association between types of urinary stones and risk factors for urinary stone formation in patients referred to Ardabil therapeutic centers. Methods : In this descriptive cross-sectional study, 150 patients with urinary stone were followed from March 2008 to July 2009 in therapeutic centers of Ardabil. Data were collected by a questionnaire include demographic factors such as age, gender, body mass index (BMI), Job and Habitation place. Data were analyzed by chi-square test and ANOVA in SPSS 16 software. The level of significance was p<0.05. Results: 116 of patients (77.3%) had calcium oxalate stone, 15 of patients (10%) had phosphate calcium stone, 10 of patients (6.7%) had acid uric and 9 of patients (6%) had phosphate ammonium stone. The mean age of patients was 41.90 + 14.41 years (48% of patients were 30-50 years old) and the mean body mass index (BMI) was 25.81+3.66. 91 of patients (60.66%) were male and 59 (39.4%) of them were female. There was no significant difference between types of urinary stones and factors including BMI the job of patient, (p=0.252), habitation place (p=0.173), history of previous illness (p=0.207) and history of drug use (p=0.247). Conclusion: The most common type of urinary stones was calcium oxalate (77.3%) in both men and women however ammonium phosphate (6%) is much less common.
