BACKGROUND: The second leading cause of cancer-related death in women is breast cancer. Xenobiotic Metabolizing Enzymes (XMEs) contribute to the detoxification of numerous cancer therapy-induced products. In the metabolism of xenobiotic, cytochrome P450s or monooxygenases perform an important function by catalysing the hydroxylation reaction. In this study, the susceptibility and genetic polymorphisms of CYP450 isoenzymes was investigated that may have an etiological role in breast cancer. AIM: The main purpose of this study was to evaluate the association of CYP1A1 (rs4646421), CYP1B1 (rs1056836), CYP2C8 (rs1058930), and CYP19A1 (rs749292) polymorphisms with the risk of breast cancer in Mazandaran province. MATERIAL AND METHODS: This cross-sectional case-control study were recruited 72 patients and 51 healthy individuals and was performed between March 2018 to May 2018 in the Oncology Department at Imam Hospital in Sari city, Iran. Peripheral blood samples were collected in EDTA tube, and DNA extraction was performed using the salting-out method and WizPrep extraction kits. Breast cancer patients with known clinicopathological characters and healthy women as control group were genotyped for genes polymorphisms by PCR-RFLP technique, using restriction enzymes. Chi-square, Fisher exact test and Logistic regression model, were applied for statistical analysis. RESULTS: The results of the experiments showed that there was a significant relationship between two groups and the age of the patients is significantly higher than the control group (p = 0.044). According to the chi-square and Fisher exact test, education, pregnancy, menopause status and oppose were significant between the two groups. Based on using a logistic regression model in two normalized and age-adjusted models to finding relationship between the genotypes of each gene and breast cancer risk, it was determined that in the CYP2C8 genotype, those who have the CG allele have a 7.74 degree increased risk of breast cancer (CI = 95% 0.95-62.5) and in the CYP19A1 gene, individuals with GA genotype, increased risk of breast cancer (CI = %95 1.52-27.21), about the CYP1B1 gene, people with two genotypes of CG + GG had higher risk of breast cancer (CI = %95 1.19-5.71) and allele G has decreased risk of breast cancer in this gene (P = 0.0271), also allele G in CYP2C8 gene had the protective effect (P = 0.02). In the age-adjusted model, for the CYP2C8 gene, GG genotype increased risk of breast cancer (CI = %95 1.11-75.84) as well as, the CG + GG genotype in CYP1B1 gene (CI = %95 1.31-6.57). CONCLUSION: Our results confirm the association between CYP2C8 (rs1058930), CYP19A1 (rs749292) and CYP1B1 (rs1056836) gene polymorphisms and increased risk of breast cancer in women in Mazandaran province.

Aims: To evaluate the mandibular bone cortical of patients with mucopolysaccharidosis on panoramic radiograph, through radiomorfometric indices. Study Design: Case-control study. Place and Duration of Study: Sample: Department of Diagnostic Imaging of the Universidade Estadual da Paraíba, Campus VIII, in the city of Araruna, PB, between January and December of 2015. Methodology: Panoramic radiographs of sixteen patients with mucopolysaccharidosis and 32 controls, organized by gender and age, composed the sample. The mandibular panoramic index, gonial index, antegonial index and mental index were evaluated. Pearson's Chi-square test, Fisher's exact test and Mann-Whitney test were used to statistical analysis with a level of significance of 5.0%. Results: Mucopolysaccharidosis patients were mostly female (62.5%), with a mean age of 12.31 + 7.16 years, MPS VI (50.0%) being the most prevalent. Patients with mucopolysaccharidosis had higher values in the gonial (1.86+0.48), the antegonical (4.36+1.24) and the mental (5.24+1.21). However, only the antegoniac index presented a significant difference (P=0.047). Conclusion: The antegoniac index was higher in patients with mucopolysaccharidosis and the other radiomorphometric measures were similar to those observed in the control group. Apparently, mucopolysaccharidosis is not related to decreased bone to mandibular quality.

Introduction and Objectives: Gastric cancer is one of the most common cancers throughout the world and it is classified as a multifactorial disease. F11R is one of the genes whose role in different cancers is proven. As miR-335-5p and miR-638 are involved in the control of F11R gene expression, and rs61803665 in the F11R gene is located at the binding site to this miRs, we investigated the possible association of this polymorphism with the risk of gastric cancer. Materials and Methods: 189 gastric cancer patients and 190 healthy individuals were enrolled in this case-control study. Genomic DNA was extracted from blood samples of the patient and the control groups. Using PCR-RLFP technique, the genotype of all samples for rs61803665 in the F11R gene was determined. The results were analyzed statistically using logistic regression and Chi-square tests. Results: The frequency of genotype AA, AG and GG in the control group were 27.90%, 40.52%, and 31.58%, respectively. The frequency of genotype AA, AG and GG in the patient groups were 24.34%, 30.68%, and 44.98%, respectively. The frequency of allele A and allele G in the control group were 48.15% and 51.85%, respectively. Besides, the frequency of allele A and allele G in the patient groups were 39.68% and 60.32%, respectively. Based on the results of statistical tests, there is a significant correlation between the risk of gastric cancer and genotype GG (P = 0.008, OR = 1.771, % 95CI=1.164-2.693) and allele G (P = 0/019, OR = 1/412, 95% CI = 1/059-1/883).Conclusion: This study showed that there is an association between allele G at the rs61803665 in the F11R gene and the increased risk of gastric cancer.

Background and Objective: Studies indicate that people with multiple sclerosis (MS) are at increased risk of sleep disorders and the resulting negative outcomes. The aim of this study was to evaluate sleep quality in patients with MS. Materials and Methods: In this case-control study, 110 patients with all confirmed types of MS as a case group and 110 healthy subjects as control group were evaluated in terms of sleep quality using Pittsburgh Sleep Quality Index (PSQI). The data collected was analyzed using t-test and chi-square tests. Results: Total score of PSQI was significantly higher in patients with MS than that of the control group (7.32 ± 2.78 vs. 5.30 ± 2.00, P = 0.001). Furthermore, PSQI scores of patients with MS was significantly higher than that of the control group in subscales including sleep latency (1.14 ± 0.99 vs 0.85 ± 0.91, P = 0.029), sleep duration (1.09 ± 0.80 vs. 0.83 ± 0.88, P = 0.048), habitual sleep efficiency (1.15 ± 0.92 vs. 0.85 ± 0.83, P = 0.017), sleep disturbance (1.25 ± 0.96 vs 0.96 ± 0.88, P = 0.013), use of sleep medication (0.69 ± 0.94 vs. 0.33 ± 0.65, P = 0.001), and daytime dysfunction (0.88 ± 0.93 vs. 32.2 ± 0.69, P = 0.001). Conclusion: Patients with MS had a significantly more improper sleep quality compared to the control group. So, poor sleep quality has a negative effect on daily activities and social communication of these patients and generally reduce their quality of life (QOL).

Background: KIF26B gene is found to play essential roles in regulating different aspects of cell proliferation and development of the nervous system. We aimed to determine if rs12407427 T/C polymorphism could affect susceptibility to schizophrenia (SZN) and breast cancer (BC), the two genetically correlated diseases. Methods: The current case-control study was performed from Aug 2018 to Dec 2018. Briefly, 159 female pathologically confirmed BC cases referring to Alzahra Hospital, Isfahan, Iran, and 102 psychologically confirmed SZN patients (60 males and 42 females) admitted to Baharan Hospital, Zahedan, Iran, were enrolled. Using the salting-out method, genomic DNA was extracted, and variants were genotyped using allele-specific amplification refractory mutation system polymerase chain reaction (ARMS-PCR) method. Results: The results revealed a significant association between the KIF26B rs12407427 codominant CT (P=0.001), CC (P=0.0001), dominant CT+CC, and recessive CC (P=0.001) genotypes with the risk of developing SZN. Significant correlations were also found regarding rs12407427 and BC susceptibility in different inheritance models, including over-dominant CT (P=0.026), dominant CT+CC (P=0.001), recessive CC (P=0.009), and codominant CT and CC (P=0.001) genotypes. The over-presence of the C allele was also correlated with an increased risk for SZN (P=0.0001) and BC (P=0.0001). Finally, computational analysis predicted that T/C variation in this polymorphism could change the binding sites in proteins involved in splicing. Conclusion: rs12407427 T/C as a de novo KIF26B variant might be a novel genetic biomarker for SZN and/or BC susceptibility in a sample of the Iranian population.
