    TOX3 and FOXA1 proteins are believed to be involved in the susceptibility of breast cancer. rs4782447 and rs4784227, as single nucleotide polymorphisms (SNPs), located at the 16q may affect the FOXA1 DNA binding sequence change and therefore may enhance the FOXA1-binding affinity to the promoter of TOX3 gene. This study aimed to investigate the association of these SNPs/haplotypes with breast cancer susceptibility in Iranian population. We conducted a case-control study of 1072 blood samples (505 breast cancer patients and 567 controls). Genotyping of rs4784227 and rs4782447 SNPs was carried out by ARMS PCR. Moreover, statistical analysis was done by SPSS 20.0 (IBM Inc., Chicago, IL, USA) and SNP analyser 2.0. There was a strongly significant statistical association between alleles and genotypes of rs4784227 with breast cancer susceptibility in a group of Iranian women (p<0.05). Moreover, a significant association was demonstrated between TA haplotype and breast cancer risk (OR=0.78; 95% CI (0.62-0.96); P-value=0.025). In this respect, although we did not observe a statistically significant association between rs4782447 with breast cancer susceptibility, the combination of the alleles of rs4784227 and rs4782447 SNPs may also affect the risk. This is in line with other studies where they suggest these SNPs as risk-associated polymorphisms by which lead to disruption of as a distal enhancer, FOXA1, binding and following that change in TOX3 expression that can eventually affect the risk of breast cancer

    Coronary heart disease (CHD) is the leading cause of morbidity and mortality globally, and specifically in Iran. Accurate assessments of Coronary heart disease (CHD) incidence is very necessary for public health. In current study we aimed to investigate the incidence of CHD and importance of several classical, modifiable and un-modifiable risk factors for CHD among an urban population in eastern Iran after 6 years of follow-up. Methods The population of MASHAD cohort study were followed up for 6 years, every 3 years in two step by phone and who reported symptoms of CVD were asked to attend for a cardiac examination, to estimate the incidence of CHD with 95% confidence interval (95% CI) as well multiple logistic regression analysis was performed to assess the association of several baseline characteristics with incidence of CHD event. Evaluation of goodness-of-fit was done using ROC analysis. CHD cases divided into four different classes which include: stable angina, unstable angina pectoris, myocardial infarction and sudden cardiac death. Results In the six years\u27 follow-up of Mashhad study, the incidence rate of all CHD event in men and women in 100,000 people-years with 95% confidence intervals were 1920 (810-3030) and 1160 (730-1590), respectively. The areas under ROC curve (AUC), based on multivariate predictors of CHD outcome, was 0.7825. Conclusion Our findings indicated that the incidence rate of coronary heart diseases in MASHAD cohort study increases with age as well as our final model designed, was able to predict approximately 78% of CHD events in Iranian population
