Abstract
BACKGROUND The stem cell marker Octamer-4 (OCT-4) is expressed in human endometrium. Menstrual cycle-dependency of OCT-4 expression has not been investigated to date. METHODS In a prospective, single center cohort study of 98 women undergoing hysteroscopy during the follicular (n = 49) and the luteal (n = 40) phases of the menstrual cycle, we obtained endometrial samples. Specimens were investigated for OCT-4 expression on the mRNA and protein levels using reverse transcriptase polymerase chain reaction (RT-PCR) and immunohistochemistry. Expression of OCT-4 was correlated to menstrual cycle phase. RESULTS Of 89 women sampled, 49 were in the follicular phase and 40 were in the luteal phase. OCT-4 mRNA was detected in all samples. Increased OCT-4 mRNA levels in the follicular and luteal phases was found in 35/49 (71%) and 27/40 (68%) of women, respectively (p = 0.9). Increased expression of OCT-4 protein was identified in 56/89 (63%) samples. Increased expression of OCT-4 protein in the follicular and luteal phases was found in 33/49 (67%) and 23/40 (58%) of women, respectively (p = 0.5). CONCLUSIONS On the mRNA and protein levels, OCT-4 is not differentially expressed during the menstrual cycle. Endometrial OCT-4 is not involved in or modulated by hormone-induced cyclical changes of the endometrium.

Abstract
BACKGROUND The present work reports on the effect of oxidizing (OH, O(2)(*-)) and reducing free radicals (e(-)(aq), H) on 17beta-estradiol (17betaE2) in respect to breast cancer initiation. The objectives of the study were based on the following premise: the ability of 17betaE2 to emit electrons (e(-)(aq)) as well as to transfer them to other biological systems. Thereby, the resulting transient hormone products are leading to the formation of metabolites, some of which may initiate the neoplastic process. The present work considers the effect of the simultaneously generated oxidizing and reducing free radicals on the carcinogenic properties of the 17betaE2 metabolites. MATERIALS AND METHODS Water-soluble 17betaE2 with incorporated 2-hydroxypropyl-beta-cyclodextrin (HBC) in various aqueous media (pH ~7.4), saturated with air, N(2)O or argon, as well as HBC alone, were exposed to the action of free radicals produced by gamma-ray. Escherichia coli bacteria (AB 1157) were used as a model for living systems. RESULTS From the survival curves obtained under different conditions, the derived DeltaD(37) values (representing the radiation dose at which N/N(0)=0.37; N/N(0) ratio: N(0)=starting number of colonies, N=number after irradiation treatment) illustrate that 17betaE2 as well as HBC act as very powerful scavengers of OH and O(2)(*-) radicals. On the other hand, 17betaE2 and HBC intermediates resulting from attack of the reducing species (e(-)(aq), H) have strong anticancer properties. CONCLUSION It is stated that DeltaD(37) values strongly depend on the reactivity of the individual free radicals. Oxidizing free radicals lead to positive DeltaD(37) values, illustrating the strongly pronounced radiation protecting ability of the systems. On the contrary, the primary reducing free radicals result in negative DeltaD(37) values, indicating anticancer effect.

Abstract
Preliminary studies have shown that systemic beta-human chorionic gonadotrophin (betaHCG) therapy alleviates endometriosis-related chronic pelvic pain. The underlying mechanism, however, is completely unknown. This study has investigated the dose-dependent alterations in the overall gene expression profile of endometriosis-derived stromal cells under increasing concentrations of betaHCG by using the Affymetrix GeneChip U133 Set. It has been previously shown that betaHCG concentrations of 0.1U/ml and higher lead to a significant and dose-dependent increase in the expression of 68 genes. This study reports on a cluster analysis which identified three clusters of genes with a comparable expression pattern in response to increasing concentrations of betaHCG. Most of the up-regulated genes encoded proteins that are involved in cell adhesion, intercellular communication, extracellular matrix remodelling, apoptosis and inflammation. Stromal monocultures from eight patients, treated with and without 50U/ml of betaHCG, were then incubated and real-time polymerase chain reaction for the highly up-regulated genes PAI2, DUSP6, PLAU and MMP1 performed in order to validate the cDNA array findings in patients with endometriosis. Taken together, this study shows that betaHCG induces dose-dependent characteristic response clusters in the gene expression profile of stromal cells obtained from endometriotic lesions which could explain the differential biological responses of betaHCG in endometriosis.

Abstract
BACKGROUND Our objective was to investigate luteinizing hormone, follicle-stimulating hormone, testosterone, and androstenedione as predicitve markers for ovulation after laparoscopic ovarian drilling. METHODS We retrospectively analyzed 100 clompihen-resistant patients with the polycystic ovary syndrome who underwent laparoscopic ovarian drilling at our department. The main outcome measure was spontaneous postoperative ovulation within three months after laparoscopic ovarian drilling. In order to predict spontaneous ovulation, we tested the following parameters by use of a univariate followed by a multivariate regression model: Preoperative serum levels of LH, FSH, testosterone, and androstenedione as well as patients' age and body mass index. In addition, we focused on pregnancy and life birth rates. RESULTS Spontaneous ovulation was documented in 71/100 patients (71.0%). In a univariate and multivariate analysis, luteinizing hormone (OR 1.58, 95%CI: 1.30-1.92) and androstenedione (OR 3.03, 95%CI: 1.20-7.67), but not follicle-stimulating hormone and testosterone were independent predictors of ovulation. Using a cut-off for luteinizing hormone and androstenedione of 12.1 IU/l and 3.26 ng/ml, respectively, spontaneous ovulation was observed in 63/70 (90.0%) and 36/42 patients (85.7%) with elevated and in 8/30 (26.7%) and 35/58 (60.3%) patients with low luteinizing hormone and androstenedione levels, respectively. The sensitivity, specificity, positive and negative predictive values for luteinizing hormone and androstendione as predictors of spontaneous ovulation after ovarian drilling were 88.7% (95%CI: 79.0-95.0%), 75.9% (95%CI: 56.5-89.7%), 90.0% (95%CI: 80.5-95.8%), and 73.3% (95%CI: 54.1-87.7%) for luteinizing hormone, and 50.7% (95%CI: 38.6-62.8%), 79.3% (95%CI: 60.3-92.0%), 85.7% (95%CI: 71.5-94.6%), and 39.7% (95%CI: 27.0-53.4%) for androstenedione, respectively. Complete one-year follow-up was available for 74/100 patients (74%). We observed a one-year pregnancy rate and a resulting life-birth rate of 61% and 51%, respectively. CONCLUSIONS Luteinizing hormone and androstenedione prior to laparoscopic ovarian drilling are independent predictors of spontaneous ovulation within three months of surgery. We suggest to preferentially performing laparoscopic ovarian drilling in patients with high luteinizing hormone and androstenedione levels.

Abstract
BACKGROUND Umbilical cord blood (UCB) is a source of human hematopoietic precursor cells (HPCs), a stem cell (SC) type that has been used in several trials for myocardial repair. A certain minimal number of cells is required for measurable regeneration and a major challenge of SC-based regenerative therapy constitutes ex-vivo expansion of the primitive cell compartment. The aim of this study was to investigate the ex-vivo expansion potential of UCB-derived HPCs and the ability of these expanded cells to migrate to the site of damage and improve ventricular function in a rodent model of myocardial infarction (MI). METHODS AND RESULTS UCB-derived HPCs, defined by coexpression of CD133 and CD34, were expanded using various cytokine combinations. MI was induced by left anterior descending artery ligation in nude rats. Cells were injected intravenously 2 days after infarction. The combination of SC factor, thrombopoietin, flt3-ligand and interleukin-6 was found to be the most effective for inducing proliferation of HPCs. The migratory capacity of expanded HPCs was similar to that of non-expanded HPCs and improvement of ejection fraction was significant in both groups, with a relative increase of >60%. CONCLUSIONS UCB-derived HPCs can be reproducibly expanded ex-vivo and retain their potential to improve cardiac function post-MI. (Circ J 2010; 74: 188 - 194).

Abstract
4-Hydroxyestrone (4-OHE(1)), a typical cancer-inducing metabolite, originating from 17beta-estradiol (17beta-E2), was chosen as a model for the studies. The aim was to get a deeper insight in the mechanisms of its ability to initiate cancer. It was found, that 4-OHE(1) can eject electrons (e(aq)(-)), when excited in the singlet state by monochromatic UV-light (lambda=254 nm) in polar media (water:ethanol=40:60 vol.%). The quantum yield Q(e(aq)(-)), determined for various 4-OHE(1) concentrations, is found to be as high as that previously observed for 17beta-E2. It decreases with increasing substrate concentration, but it is enhanced at higher temperature. The ability of 4-OHE(1) to eject as well as to consume and to transfer electrons to other biological systems, classifies it as an electron mediator, similar to 17beta-E2. The 4-OHE(1) transients resulting of the electron emission process are leading to the formation of secondary metabolites. Surprisingly, it was established that the secondary metabolites possess likewise the ability to eject as well as to consume electrons. Hence, they behave similar like 17beta-E2. However, the structure of the secondary formed metabolites, which determinates their biological properties and carcinogenity, depends on the nature of the available reaction partners involved in their formation. A probable reaction mechanism explaining the subject matter is discussed.

Abstract
OBJECTIVE Persistent Chlamydia trachomatis infections are associated with tubal pathology. We studied whether sampling from multiple sites would increase the identification of the infections. DESIGN Prospective cohort study. SETTING Tertiary care facility. PATIENT(S) Two hundred two infertile women. INTERVENTION(S) Smears were taken from the cervix, urethra, high vagina, fimbriae and the Douglas cavity. Blood samples were collected and tubal patency was assessed by pertubation with lipiodol and methylene blue. MAIN OUTCOME MEASURE(S) Detection of C. trachomatis DNA, detection of IgA and IgG antibodies against C. trachomatis, and antibodies against chlamydial heat-shock protein 60, tubal patency. RESULT(S) Chlamydia trachomatis was detected in 2 of 202 patients, for an overall prevalence of 1%. In both patients PCR results were positive in the cervical, vaginal, and urethral specimens. Chlamydia trachomatis IgG, IgA, and chlamydial heat-shock protein 60 IgG were significantly more prevalent in women with distal tubal pathology than in those without (26/40 [65.0%] vs. 16/162 [9.9%], 9/40 [22.5%] vs. 7/162 [4.3%], and 34/40 [85.0%] vs. 34/162 [21.0%]). Bacterial colonization was found in 1 of 202 samples from the Douglas cavity. CONCLUSION(S) Routine DNA testing for C. trachomatis should be confined to cervical sampling. The association between tubal pathology and seropositivity of IgG, IgA, and cHSP60 IgG was confirmed but did not add clinically valuable information during the diagnostic workup of infertility patients.

Abstract
BACKGROUND There is increasing awareness of the opportunity that many contraceptive interventions may provide for additional health benefits. However, treatment of medical problems with oral contraceptives (OCs) is often an 'off-label' practice. OBJECTIVE The aim of this review is to summarize available data on non-contraceptive benefits of OCs. METHODS Review of the literature. RESULTS OCs have been shown to reduce the risk of ovarian, endometrial, and colorectal cancer. It has been suggested that OCs may be used in treatment of endometriosis, menorrhagia, and uterine leiomyomas. Pelvic inflammatory disease, dysmenorrhea, premenstrual syndrome, and acne have been shown to improve under OCs. CONCLUSION OCs are important for global and female health. Besides contraception, non-contraceptive effects of OCs are evidence based, well established, and commonly used in clinical practice.

Abstract
OBJECTIVE To systematically monitor the frequency and risk factors of adverse events (AEs) in a reproductive surgery endoscopy unit. DESIGN Prospective cohort study. SETTING Academic research institution. PATIENT(S) All consecutive surgical patients of a reproductive surgery unit from December 2005 to March 2007. INTERVENTION(S) Monitoring for predefined AEs by trained observers. MAIN OUTCOME MEASURE(S) Number of preventable and not preventable AEs, medical errors, and system problems. Univariate analysis and multivariate logistic regression were used to identify risk factors of AEs. RESULT(S) Seven hundred ninety-six women were included. We identified 60 AEs in 45 patients (risk 6%; 95% confidence interval [CI] 1%-11%). Adverse events were postoperative fever (n = 1), wound breakdown (n = 1), intraoperative or postoperative administration of packed erythrocytes (n = 6), surgical revision (n = 7), unplanned readmission (n = 5), transfer to intensive care unit (n = 1), conversion (n = 8), intraoperative organ injury (n = 9), blood loss >500 mL (n = 3), surgery canceled (n = 15), and other AEs (n = 4). Six patients (risk 0.8%; 95% CI 0-2%) had multiple AEs. One (0.01%) and 11 (1.4%) AEs were deemed due to medical errors and system problems, respectively. Twelve and 48 AEs were deemed preventable and not preventable, respectively. In a univariate and multivariate analysis, only duration of surgery (odds ratio 3.78; 95% CI 1.95-7.33) was significantly associated with having an AE. CONCLUSION(S) Clinical outcome monitoring is a useful tool for assessing the outcome quality of reproductive surgery by identifying potentially preventable AEs and associated risk factors.

Abstract
It was established for the first time, that the sexual hormones 17beta-estradiol (17betaE2) and progesterone (PRG) are able to emit electrons from their excited single state in water-ethanol mixtures. The yield of the "solvated electrons" (e(s)(-)) depends on the substrate concentration, the ratio of water-alcohol-mixtures and the temperature. The e(s)(-) yield obtained from 17betaE2 is by two orders of magnitude higher than this of PRG. The possible relationship of the resulting hormone transients from 17betaE2 leading via specific metabolites to breast cancer is discussed.

Abstract
BACKGROUND There is mounting evidence that menopause affects some functions of the skin. Hormone replacement therapy (HRT) appears to limit some of the climacteric aspects of cutaneous aging. OBJECTIVE In the light of a growing interest in the endocrinological influence of skin, we performed a study evaluating the effects of HRT on skin aging in postmenopausal women. METHODS Forty non-hysterectomized, postmenopausal women were included in this prospective, randomized, double-blind, placebo-controlled study on the influence of oral sequential treatment with a combination of 2 mg 17beta-estradiol/10 mg dydrogesterone (Femoston) for seven 28-day cycles. Skin elasticity, skin surface lipids, skin hydration and skin thickness were measured by non-invasive methods, and both adverse-event profile and clinical-dermatological status were evaluated. RESULTS After 7 months of HRT, skin elasticity increased significantly at the right ramus of the mandible, while skin hydration tended to improve significantly at the right upper arm (inner side); skin thickness improved significantly but skin surface lipids did not. Absolute effects did not differ significantly between HRT and placebo patients. A dermatological evaluation was largely consistent with measurement results. Safety and tolerability of HRT were positive. CONCLUSION The results showed improvements in the parameters involved in skin aging in the HRT group as compared to baseline. While skin aging is no indication for systemic hormone supplementation, a positive effect on aging skin can be observed.
