Background: Mild cognitive impairment (MCI) accompanies brain atrophy in neuroimaging investigations. The aim of this study was to compare MCI patients with the normal population for hippocampal volume (HV) and hippocampal angle (HA), and to assess the correlation between HV and HA. Materials and Methods: In a case-control study on 2014, in Kashani Hospital (Isfahan, Iran), 20 MCI patients were compared with 20 normal controls for HV and HA. Subjects were diagnosed with MCI or normal control, based on neuropsychiatry interview, which was confirmed by neuropsychiatry unit cognitive assessment tool (NUCOG). All magnetic resonance imaging scans were processed using the Free-Surfer software package for HV assessment. The HA was measured on the most rostral slice in which the uncal sulcus could be identified on a coronal plane. The data were analyzed using multiple analysis of co-variance and Pearson correlation. Results: The mean (standard deviation [SD]) score of NUCOG in control and case group were 91.05 (3.01) and 82.42 (3.57), respectively. Comparison of HV and HA scores in two groups, showed that mean (SD) HV and HA were not different between control and case groups, significantly, (P = 0.094 and P = 0.394, respectively). There was a negative correlation between the adjusted HV and the HA in case (r = −0.642, P = 0.004), and control groups (r = −0.654, P = 0.003). Conclusion: HV and HA were not different between MCI patients and normal controls; however, HA is correlated with HV negatively and may be used as an alternative factor because of more feasibility and availability in clinical settings in compared to HV.

Background: Breast cancer (BC), is the most common cancer in women, that is the major cause of cancer-related morbidity and mortality in women. Obesity is considered as a major risk factor for BC that increases both the rate and intensity of the disease. Polymorphisms in FTO gene, a known obesity related gene, is shown to be associated with obesity-related traits as well. The aim of this study was to evaluate the association between previously reported single nucleotide polymorphisms (SNPs) of intron 1of FTO gene, rs1477196 and rs9939609 and risk of BC in a subset of Iranian BC patients. Materials and Methods: We genotyped 99 cases and 100 controls for the two SNPs of rs9939609 and rs1477196 by TaqMan allelic discrimination assay. For each sample in an allelic discrimination assay, a unique pair of fluorescent dye probe is used. One fluorescent dye probe has a perfect match with the wild type allele and the other fluorescent dye probe is perfectly matched to the mutated allele. Results: Our research has shown that the observed differences between case and control groups in the studied SNPs of FTO gene are not statistically significant (P > 0.05). Conclusions: Our findings suggest that there is no association between rs9939609 and rs1477196 polymorphisms in FTO gene and increase in risk of BC in the studied Iranian population. These results were inconsistent with that of previously reported case-control studies with BC that means presence of these polymorphisms depends on ethnic group.
