Investigation on the relationship between personal characteristics with lip, jaw and philtrum dimensions

Background: The relationship between the sizes of the structures that form our face, such as lips, philtrum, and the jaw, and our personality characteristics are unknown. In this study, it was scientifically researched whether lip, jaw and philtrum anatomy can give us clues on personality characteristics or not.Methods: The photographs of the university students were taken using digital camera in two positions. The students who were photographed were asked to simultaneously complete personality test. The photographs were transferred to the computer and, using photoshop program installed on the computer, measurements were made. The mouth widths, upper and lower lip thicknesses, the distance between lip spots, philtrum length and width, lateral mouth width, jaw heights were recorded, and lip type and philtrum depth were identified. The results were compared to the personality characteristics of the students.Results: Lip thicknesses were found to be correlated positively only with the ‘openness to experience’ trait from among personality characteristics. A positive correlation between lip type and ‘conscientiousness’ was also found. There was a negative correlation between philtrum length and ‘negative valence’.Conclusions: This study shows that lip thickness and philtrum length can give us an idea regarding personality characteristics

Investigation of variants of critically important antioxidant enzyme genes in patients with polycystic ovary syndrome

Aim: To investigate the possible effects of polymorphisms in genes encoding some important antioxidant enzymes such as super oxide dismutase 2 (SOD2), glutathione peroxidase 1 (GPX1), endothelial NOS (eNOS) and catalase (CAT) in patients with polycystic ovary syndrome (PCOS).Methods: Peripheral blood of 100 patients with PCOS and 100 healthy control group were collected, Polymorphisms in related genes was investigated by using polymerase chain reaction-restriction fragment length polymorphism. In addition, the related biochemical values of the patients were also investigated.Result: In our study there is no significant results for SOD2 gene but the results obtained between GPX1, eNOS and CAT genes were significant. Fasting blood sugar (FBS), insulin, triglyceride, waist circumference and dehydroepiandrosterone sulphate (DHEAS) were found to be significant with the disease, whereas follicle-stimulating hormone (FSH) was found to be effective in preventing the disease.Conclusions: These findings suggest that polymorphisms in genes encoding GPX1, eNOS and CAT enzymes may be associated with PCOS. Additionally, it is thought that the genes of FBS, triglyceride, insulin, DHEAS and waist circumference are important in the pathogenesis of the disease in the presence of homozygous mutation

Evidence for heterogeneity in response to treatment in mammary tumors of dogs as happens in humans

Tumors are formed by various clones developed over a long time. This gives rise to a heterogeneous nature. This heterogeneity is the hardest challenge in the treatment of cancers because it is the main reason for drug resistance. This is a well-known fact in human cancer. Therefore, we have reasoned that if the tumor heterogeneity in canine mammary gland tumors (CMGTs) could be shown by an ex vivo assay, which will be used first time in veterinary oncology practice, this could be used further in clinics. To achieve this, twenty-six patients were included in the study. Tumor tissues were obtained from animals during routine surgery. Tumor cells were isolated and seeded ex vivo. The cells were exposed to anticancer drugs that are clinically used. Seven days after the treatment, chemosensitivity has luminometrically been assayed by ATP-tumor chemosensitivity assay (ATP-TCA). It has clearly been shown that all the tumor tissues have responded to treatment differently, implying that heterogeneity exists in mammary tumors. There has also been found that there was a weak to moderate statistically significant correlation between tumor size and drug index. However, there has been no correlation between drug index and metastasis to lymph nodes. Hyperplasic areas had relatively higher PCNA values. The results of our study demonstrate the heterogeneity in responses to in vitro drugs. Clinical trials based on test results and follow-up studies with large numbers of animals are needed to prove that such chemotherapeutic activity assessment tests can be clinically useful in predicting drug responses in CMGTs
