Heterotopic transplantation of cryopreserved ovarian tissue in cancer patients: a case series.

Transplantation of cryopreserved ovarian tissue offers patients a chance to preserve fertility during cancer treatment. In this study of ten young women with gynecological cancer, heterotopic sites were tested for serum hormones and follicle growth to estimate transplant longevity and prospects for assisted conception. Frozen-thawed grafts were implanted subcutaneously in the forearm (FA) (2 cases), the abdominal wall (AW) (11 cases), and the peritoneal lining (P) (3 cases) .

CLINICAL FEATURES OF THERAPY OF ANEMIA AND THE SIGNIFICANCE OF ITS FLUCTUATION IN THE DEVELOPMENT OF ANEMIA IN DIALYSIS PATIENTS.

The aim of our study was to examine the features of therapy of anemia, and the influence of fluctuation in dose of antianemic drugs on hemoglobin levels in dialysis patients. The study included 100 patients with chronic kidney disease stage 5D receiving hemodialysis, mean age was 53,4±15,8 years. The clinical and anamnestic data were studied and laboratory tests were performed in all patients.

Outcomes of IVF cycles coupled with PGS by aCGH of embryos from donor and autologous oocytes, transferred after vitrification to women of advanced maternal age.

It is well documented that aneuploidy rate in preimplantation embryos increases with the mother's age, and at the same time the number of oocytes diminishes. Consequently, for patients of advanced maternal age two options are available to overcome these limitations: use of oocytes from young donors, or use of own oocytes coupled with preimplantation genetic screening (PGS) for 24 chromosomes. However, it is not clear which strategy might be more effective.

[Case of restoration of reproductive function using the method of cryopreservation and autotransplantation of ovarian tissue in a Hodgkin's lymphoma patient].

Recent advances of cancer treatment resulted in the increase of patient survival rate. Treatment for Hodgkin’s lymphoma (HL) may impair reproductive function, which leads to a decrease of the quality of life of cancer survival. Today different approaches have been developed for fertility preservation, one of which is the cryopreservation of ovarian tissue with subsequent orthotopic transplantation.

Fluorescent microscopic study of epithalon binding in maternal and fetal rabbit tissues in health and under conditions of placental insufficiency.

Epithalon (regulatory tetrapeptide) labeled with dansil (fluorescent stain) easily penetrates into all tissues and organs of pregnant rabbit females and through the placenta into fetal organs. Incorporation of labeled epithalon in placental tissues is more often observed in fetuses developing under conditions of placental insufficiency than in normal fetuses.
