Cytokine components and mucosal immunity in the oviduct of Xenopus laevis (amphibia, pipidae)
2011
Abstract Most studies on the mucosal immunity in female reproductive tissues have been performed in mammals. In all species, apart from their reproductive strategies, immunity in the genital mucosa is required to defend the host against luminal pathogens. In this study we investigated the role of the innate immunity of the oviductal mucosa of Xenopus laevis , an amphibian characterized by external fertilization. In particular we examined the expression and localization of Interleukin-1β (IL1B), Macrophage migration inhibitory factor (MIF) and Interleukin-1 receptor type 1 (IL1R1) in different oviductal portions including an upper glandular region, an intermediate and a lower aglandular regi…
Long term complications following pelvic and para-aortic lymphadenectomy for endometrial cancer, incidence and potential risk factors: a single insti…
2019
ObjectiveTo determine the incidence of long term lymphadenectomy complications in primary surgery for endometrial cancer and to elucidate risk factors for these complications.MethodsA retrospective chart review was carried out for all patients with endometrial cancer managed at Parma University Hospital Unit of Gynecology and Obstetrics between 2010 and 2016. Inclusion criteria were surgical procedure including hysterectomy and lymphadenectomy (pelvic or pelvic and aortic). We identified patients with postoperative lymphocele and lower extremity lymphedema. Logistic regression analysis was used to identify predictive factors for postoperative complications.ResultsOf the 249 patients tested,…
EMAS position statement: Predictors of premature and early natural menopause.
2019
Simoncini, Tommaso/0000-0002-2971-0079; Chung, Hsin-Fang/0000-0003-3261-5942; Mishra, Gita/0000-0001-9610-5904 WOS:000468709100014 PubMed ID: 31027683 Introduction: While the associations of genetic, reproductive and environmental factors with the timing of natural menopause have been extensively investigated, few epidemiological studies have specifically examined their association with premature (< 40 years) or early natural menopause (40-45 years). Aim: The aim of this position statement is to provide evidence on the predictors of premature and early natural menopause, as well as recommendations for the management of premature and early menopause and future research.

DNA fragmentation index, pAKT and pERK1/2 in cumulus cells are related to oocyte competence in patients undergoing in vitro fertilization programme
2019
SummaryActivated pERK1/2 and pAKT are key players in supporting cell survival and proliferation pathways. Translocation of pERK1/2 into the nucleus, where it interacts with transcription factors and DNA itself, is instrumental in exerting an anti-apoptotic effect. In this study, pAKT levels, pERK1/2 nuclear localization and DNA fragmentation index (DFI) in cumulus cells of single cumulus–oocyte complexes of patients undergoing in vitro fertilization programmes were evaluated and correlated with the clinical outcome of the related embryos. For a positive clinical outcome of blastocyst development, pERK1/2 nuclear localization and DFI value had a significant inverse relationship, whereas the …
Fertility in McCune Albright syndrome female: A case study focusing on AMH as a marker of ovarian dysfunction and a literature review.
2021
Abstract Background The molecular basis of McCune Albright syndrome (MAS) is a recurrent GNAS Postzygotic gain of function sporadic mutation, resulting in a mosaic disease. Most of girls present precocious puberty, caused by the development of recurrent ovarian cysts with autonomous Hyperestrogenic stimulation. After menarche, the majority of patients with ovarian GNAS mutation have menstrual disturbances and infertility. Objectives We wanted to focus on the fertility of MAS females and propose an appropriate management, by a detailed case report and an exhaustive review of the literature on fertility and pregnancy in MAS females. Results We present the case of a 29-year-old MAS female, who…
Positive association of high-density lipoprotein cholesterol with lumbar and femoral neck bone mineral density in postmenopausal women.
2021
Abstract Objective Experimental studies suggest that lipids affect bone metabolism. We aimed to elucidate whether lipid levels are associated with bone mineral density (BMD) in a cohort of postmenopausal women. Design A cross-sectional study of participants in the Chronic Ailment Reduction after MENopause (CARMEN) cohort. Women underwent assessment of clinical and analytical parameters, including fasting lipid levels. BMD was assessed at both lumbar spine and hip. Homogeneity in the cohort was optimized by filtering out a series of confounding variables with a known impact on bone. Main outcome measures Association of BMD at lumbar spine and femoral neck with lipid levels. Results A total o…
Associations of physical performance and physical activity with mental well-being in middle-aged women
2021
Abstract Background To investigate whether physical performance is independently of physical activity (PA) associated with positive and negative dimensions of mental well-being in middle-aged women. Methods Data were drawn from the Estrogenic Regulation of Muscle Apoptosis (ERMA) study in which women 47 to 55 years were randomly selected from the Finnish National Registry. They (n = 909) participated in measurements of physical performance (handgrip force, knee extension force, vertical jumping height, maximal walking speed, and six-minute walking distance). Both mental well-being (the Centre for Epidemiologic Studies Depression Scale, the International Positive and Negative Affect Schedule…
Do allopatric male Calopteryx virgo damselflies learn species recognition?
2012
There is a growing amount of empirical evidence that premating reproductive isolation of two closely related species can be reinforced by natural selection arising from avoidance of maladaptive hybridization. However, as an alternative for this popular reinforcement theory, it has been suggested that learning to prefer conspecifics or to discriminate heterospecifics could cause a similar pattern of reinforced premating isolation, but this possibility is much less studied. Here, we report results of a field experiment in which we examined (i) whether allopatric Calopteryx virgo damselfly males that have not encountered heterospecific females of the congener C. splendens initially show discri…
Surrogacy relationships: a critical interpretative review
2020
Abstract Based on a critical interpretative review of existing qualitative research investigating accounts of ‘lived experience’ of surrogates and intended parents from a relational perspective, this article proposes a typology of surrogacy arrangements. The review is based on the analysis of 39 articles, which belong to a range of different disciplines (mostly sociology, social psychology, anthropology, ethnology, and gender studies). The number of interviews in each study range from as few as seven to over one hundred. Countries covered include Australia, Canada, Greece, India, Iran, Israel, Italy, Mexico, Norway, Russia, Sweden, UK, Ukraine, and the USA. Most studies focus only on surrog…
Effects of Oral Supplementation with Myo-Inositol and D-Chiro-Inositol on Ovarian Functions in Female Long-Term Survivors of Lymphoma: Results from a…
2022
The progressive improvement of lymphoma treatment has led to an important prolongation of patient survival and life expectancy. The principal international scientific societies of oncology now therefore recommend that long-term survivors of lymphoma join fertility programs. Specifically, fertile-age patients should be assisted by a multidisciplinary team, including specialists dedicated to fertility preservation in oncology, in order to support the completion of their reproductive project. In the general population, the use of Myo-Inositol and D-Chiro-Inositol (MI/DCI) has been demonstrated to be an effective choice to treat ovarian dysfunctions, with a consequent improvement in reproductiv…
