Combination of gonadotropin-releasing hormone (GnRH) agonists with GnRH antagonists before chemotherapy reduce but does not completely prevent a follicle-stimulating hormone flare-up

Increasing evidence supports GnRH agonists to be an effective treatment to preserve ovarian function during chemotherapy, but the initial flare-up of FSH during the first week after GnRH agonist application still limits its use. The combination of GnRH agonists with GnRH antagonists might solve this problem to some extent as the addition of GnRH antagonists at least significantly reduces the FSH flare-up.

Efficacy and safety of ovarian stimulation before chemotherapy in 205 cases

Ovarian stimulation and cryopreservation of fertilized oocytes before cancer therapy is the best established and efficient fertility preservation technique and should still be considered before chemotherapy. Within a short time frame of 2 weeks, between 8.6 (18-25 y) and 5.1 (36-40 y) fertilized oocytes can be cryopreserved.

Increased endometrial placenta growth factor (PLGF) gene expression in women with successful implantation

To analyze the vascularization of the endometrium via hysteroscopy and to assess its correlation with angiogenic factor gene expression and embryo implantation rate.

Vaginal prolapse, pelvic floor function, and related symptoms 16 years after sex reassignment surgery in transsexuals

To evaluate the prevalence of prolapse and related bladder, bowel, and sexual problems in transsexual patients (TS) after sex reassignment surgery.

Xenotransplantation of cryopreserved ovarian tissue from patients with ovarian tumors into SCID mice--no evidence of malignant cell contamination

This study examined the possible presence of malignant cells in ovarian cortex from patients with ovarian tumors after xenografting of the ovarian tissue into severe combined immunodeficiency mice. None of the mice presented symptoms of reintroduced malignancy nor did microscopic and immunohistochemical evaluation of the grafts raise any suspicion of residual malignant disease.

Peroxisome proliferating activating receptor gamma-independent attenuation of interleukin 6 and interleukin 8 secretion from primary endometrial stromal cells by thiazolidinediones

To assess the effect of thiazolidinediones on the regulation of inflammatory cytokines related to endometriosis in endometrial tissue and determine whether these effects occur via activation of the peroxisome proliferating activating receptor gamma (PPAR)-γ.

Endometriosis-associated nerve fibers, peritoneal fluid cytokine concentrations, and pain in endometriotic lesions from different locations

To assess the relationship between endometriotic lesions with associated nerve fibers with both pain and peritoneal fluid (PF) cytokine concentrations based on lesion location.

Experimental contamination assessment of a novel closed ultravitrification device

To evaluate the safety of a new ultravitrification closed device.

Reduced pretreatment ovarian reserve in premenopausal female patients with Hodgkin lymphoma or non-Hodgkin-lymphoma--evaluation by using antimüllerian hormone and retrieved oocytes

To study whether the ovarian reserve in female lymphoma patients is already reduced before the start of chemotherapy.

Discovery of insertion element ISCfe1: a new tool for Campylobacter fetus subspecies differentiation

The species Campylobacter fetus is divided into the subspecies C. fetus subsp. venerealis (CFV) and C. fetus subsp. fetus (CFF). CFV is the causative agent of bovine genital campylobacteriosis, a highly contagious venereal disease that may lead to serious reproductive problems, including sterility and abortion. In contrast, CFF can be isolated from the gastrointestinal tract of a wide range of host species, is associated with abortion in sheep and cattle, and can also be isolated from local and systemic infections in humans. Despite differences in host and niche preferences, microbiological differentiation of the two subspecies of C. fetus is extremely difficult. This study describes the identification of a new insertion element, ISCfe1, which is present exclusively in CFV strains, with highly conserved specific ISCfe1 insertion sites. The results are useful for identification and differentiation of the two C. fetus subspecies and will help in understanding the evolution and pathogenesis of C. fetus.
