1. Artesunate promotes Th1 differentiation from CD4+ T cells to enhance cell apoptosis in ovarian cancer via miR-142
The aim of this study was to evaluate the influence of artesunate on Th1 differentiation and its anti-tumor effect on ovarian cancer. A Murine ovarian cancer model was established by ID8 cells transplantation. The expression of miR-142 and Sirt1 proteins in peripheral CD4+ T cells were quantified with qRT-PCR and western blot, respectively. Peripheral CD4+ T

2. Random-start controlled ovarian stimulation for emergency fertility preservation in a patient with myelodysplastic syndrome: a case report
This study reports a case of a gonadotropin-releasing hormone agonist trigger in a young female with myelodysplastic syndrome (MDS) who underwent fertility preservation using random-start controlled ovarian stimulation. This method involves the stimulation of the ovary regardless of a patient's menstrual-cycle phase. A review of the related literature is als

3. N-acetylcysteine improves morphologic and functional aspects of ovarian grafts in rats
PURPOSE: To evaluate morphological and functional aspects of the ovarian graft in transplanted rats treated with NAC. METHODS: Female Wistar rats, virgin, 3 to 4 months old, weighing 200-250 grams were used in experiments. The rats have been kept in proper sanitary conditions, receiving food and water ad libitum. Five groups (n=10, each) were constituted: 4

4. Experimental ovarian transplantation on stomach for bone repair in ovariohysterectomized rabbits
PURPOSE: To evaluate the bone repair process in ovariohysterectomized rabbit submitted to an ovarian transplant to stomach that may supplying some quantity of estrogen occurs to improve bone healing. METHODS: In 20 female rabbits three holes of 1, 2 and 3mm diameter in tibial shaft were made and after that all animals received OHE through a ventral incision

5. Autologous and allogeneic ovarian orthotopic transplantation: morphologic, endocrinologic and natural pregnancy assessment
PURPOSE: To assess pregnancy of rabbits submitted to bilateral ovariectomy and orthotopic allogeneic or autologous intact and sliced ovarian transplantation without a vascular pedicle and to determine the morphofunctional aspects of the transplanted ovaries. METHODS: Fifty-six female rabbits were studied. The ovaries were removed and orthotopically transplan

6. Transplante experimental, subcutâneo e intraperitoneal, de ovário em suínos: estudo histomorfométrico e imunoistoquímico / Experimental transplantation, subcutaneous and intraperitoneal, ovary in pigs: immunohistochemical and histomorphometric study
O transplante autólogo de tecido ovariano constitui alternativa relevante na preservação da fertilidade e da função hormonal ovariana em mulheres sujeitas à falência ovariana prematura e infertilidade, por causas malignas, tratamentos adjuvantes ou cirurgias. É a única opção para crianças, fase pré-puberal e para mulheres que não podem retardar

8. Transplante autólogo de tecido ovariano para o peritônio de ratas após congelamento e descongelamento
One of the major problem against reproductive medicine is the incapacity of oocyte preservation. In these cases, ovary preservation could restore hormonal e fertility capacity. Objective: Assess the ovarian function after removal of the ovaries, cryopreservation and intraperitoneal autotransplantation. Design: Prospective experimental study involving 67 rats

9. The subcutaneous auto-transplantation ovaries and follicular depletion in domestic catas (felis catus) / Autotransplantação de ovário no subcutâneo e consumo folicular em gatas domésticas (felis catus)
The main goal of this study was to establish the follicular depletion of the remaining and implanted ovaries in the subcutaneous in domestics cats after 120 days, by quantification and morphometric classification, and with respect to the preservation of the tissue organization. Thirteen female domestic cats (Felis catus) were used, distributed into two group

11. Transplantation of Young Ovaries to Old Mice Increased Life Span in Transplant Recipients
Previously we reported that prepubertally ovariectomized mice that received young transplanted ovaries at a postreproductive age showed a 40% increase in life expectancy. To study this phenomenon in greater detail, 11-month-old ovariectomized and ovary-intact CBA/J mice underwent ovarian transplantation with 60-day-old ovaries or a sham surgery. Results from

12. Nitric oxide is an important mediator for tumoricidal activity in vivo.
When cultured in vitro, peritoneal macrophages, obtained from mice previously inoculated with bacillus Calmette-Guérin, release nitric oxide, which is cytostatic and/or cytolytic for tumor cells. However, it is not known whether nitric oxide has antitumor effects in vivo. Here we demonstrate that nitric oxide is an important mediator of host resistance to s
