Cancer And Ovarian Tissue Cryopreservation, Yavuz Emre Şükür, Batuhan Özmen, Murat Sönmezer

Turkish Journal of Medical Sciences

Although ovarian tissue cryopreservation is still accepted as an experimental procedure, it has recently become an increasingly resorted technique in highly specialized in vitro fertilization (IVF) clinics. Its indications include many childhood cancers, breast cancer, some autoimmune diseases, hematopoietic stem cell transplantation, and pelvic radiation therapy due to solid tumors. The chemotherapeutics and radiation therapy may diminish ovarian reserve and cause premature ovarian failure. It currently seems as the only option for fertility preservation in children where ovulation induction is ethically not acceptable, and for those when cytotoxic therapy is urgent. There are 2 main methods for transplantation of frozen-thawed …

The measurement of ocular alignment can be challenging and difficult to reproduce. A method for the measurement of ocular alignment with accuracy, speed, and reproducibility would be a useful clinical addition. Materials and methods: A hand-held device consisting of a rotary prism and a red Maddox rod was constructed. This was used to evaluate 18 patients with ocular misalignment and the results were compared with the ones obtained using the prism cover testing. Results: The results from the hand-held device showed a close correlation with those of the prism cover test. Conclusion: The hand-held instrument is a useful method to …

To investigate the effects of ingesting Fructus vitis minuta (black grape) on plasma and erythrocyte antioxidant parameters in elderly subjects. Materials and methods: Thirteen subjects (mean age 74.67 ± 0.58) participated in the study. They consumed 1 g/kg body weight per day of dried black Maraş grapes for 1 month. Before and after these periods, fasting blood samples were obtained, and oxidant (as MDA) and antioxidant (as SOD) parameters were studied in erythrocytes. Also, plasma samples were obtained from the subjects. Results: In the erythrocyte hemolysate, MDA (malondialdehydes) levels and SOD (superoxide dismutase) activities were found to be lower (P < 0.01) in the second samples compared to the first ones. Conclusion: We think that because free radical production was decreased SOD activities were not increased. Our results show that reduced peroxidation processes caused by Maraş grape consumption suggest that grape consumption has beneficial effects in elderly subjects.
