The objectives of the current experiment were to evaluate the effects of intrauterine infusion of Escherichia coli lipopolysaccharide (LPS) in cows diagnosed with purulent vaginal discharge (PVD) on intrauterine cell population, resolution of PVD, uterine health, and reproductive performance. Jersey cows (n = 3,084) were examined using the Metricheck device to diagnose PVD at 35 ± 6 d postpartum. Purulent vaginal discharge was defined as the presence of purulent (≥50% pus) discharge detectable in the vagina...

Accurate knowledge of the composition and ecology of the vaginal microbial environment in healthy women is necessary for understanding lactobacilli-dominated normal microbiota and the mechanisms by which it reduces disease risk. The vagina and its microbiota form a balanced ecosystem; any movement outside the normal range for this ecosystem of obligate and/or facultative microbes, termed dysbacteriosis, can lead to infection and disease. This review summarizes recent research on the vaginal ecosystem, the Lactobacillus species that dominate it, and the means by which they suppress the growth, development, and/or proliferation of pathogenic microbial species...

Pelvic Organ Prolapse (POP) is a major clinical burden affecting 25% of women, with vaginal delivery a major contributing factor. We hypothesised that increasing parity weakens the vagina by altering the extracellular matrix proteins and smooth muscle thereby leading to POP vulnerability. We used a modified POP-quantification (POP-Q) system and a novel pressure sensor to measure vaginal wall weakness in nulliparous, primiparous and multiparous ewes. These measurements were correlated with histological, biochemical and biomechanical properties of the ovine vagina...

In recent years, microbiome research has revealed multiple essential roles of the microorganisms residing within the human body in host metabolism, immunity, and overall health. Numerous physiological and pathological states, including obesity and the metabolic syndrome, have been correlated with microbial changes, termed dysbiosis. Our microbiomes change in response to our environment, diet, weight, hormones, and other factors. It is, therefore, not surprising that there are also significant changes in the microbiome during pregnancy when dramatic weight gain and metabolic and immunological changes occur...

Acellular matrix materials have been widely used to repair various tissues and organs. According to the plastic principle, when a part of the body is lost, it should be replaced with a similar material. Therefore, the use of a homologous organ-specific acellular vaginal tissue in vagina reconstruction repair surgery may show good results. However, the acellular vagina matrix (AVM) form large vertebrates is difficult to isolate. In this study, we described a multistep method to prepare porcine AVM and evaluated the efficacy of acellularization...

Gel-forming mucins are macromolecules produced by goblet cells and responsible for the mucus gel formation. Changes in goblet cell density and in gel-forming mucin production have emerged as sensitive indicators for mucosal diseases. A Muc5b-GFP tagged reporter mouse was used to assess Muc5b production in mouse tissues by immunofluorescence microscopy and fluorescent activity using stereromicroscopy and probe-based confocal laser endomicroscopy. Muc5b production was followed longitudinally by recording the fluorescent activity in vagina and in embryonic lung explants under stimulation by interleukin 13...

Despite acute inflammation by polymorphonuclear neutrophils (PMNs) during vulvovaginal candidiasis (VVC), clearance of Candida fails to occur. The purpose of this study was to uncover the mechanism of vaginal PMN dysfunction. Designs included assessing PMN migration, proinflammatory mediators, and tissue damage (by analysis of the activity of lactate dehydrogenase [LDH]) in mice susceptible (C3H/HeN-C57BL/6) or resistant (CD-1) to chronic VVC (CVVC-S or CVVC-R) and testing morphology-specific Candida albicans strains under conditions of preinduced PMN migration (CVVC-S mice) or PMN depletion (CVVC-R mice)...

Zika virus (ZIKV) infection is associated with congenital malformations in infected fetuses and severe neurological and other systemic complications in adults. There are currently limited anti-ZIKV treatment options that are readily available and safe for use in pregnancy. In this drug repurposing study, bromocriptine was found to have inhibitory effects on ZIKV replication in cytopathic effect inhibition, virus yield reduction, and plaque reduction assays. Time-of-drug-addition assay showed that bromocriptine exerted anti-ZIKV activity between 0 and 12 h post-ZIKV inoculation, corroborating with post-entry events in the virus replication cycle prior to budding...

Human papilloma virus (HPV) is considered to be responsible for a large part of vaginal and vulvar carcinomas, and the p53 codon 72 polymorphism has been implicated in susceptibility to cancer induced by this virus, but with contradicting results. In this study, we have investigated the prognostic value of the codon 72 polymorphism by real-time PCR (qPCR) in two cohorts of vaginal (n = 66) and vulvar (n = 123) carcinomas. In vaginal carcinoma, arginine homozygous patients were significantly associated with a higher primary cure rate (p = 0...

Strain elastography (SE) is a new technique of parametric imaging that allows quantification of the elasticity of tissue. The aim of our study was to determine if the elasticity of para-urethral tissue correlates with urethral mobility and urinary incontinence (UI). Ninety-nine unselected women were investigated with SE. They were given a standardized interview about UI, and SE raw data for the para-urethral tissue were acquired in a sagittal standard urethra-symphysis view while being stimulated by a coughing fit...

OBJECTIVE: To illustrate the marked differences between classical endocrinology that distributes hormones to all tissues of the body through the bloodstream and the science of intracrinology, whereby each cell of each peripheral tissue makes a small and appropriate amount of estrogens and androgens from the inactive precursor dehydroepiandrosterone (DHEA), DHEA being mainly of adrenal origin. Because only the inactivated sex steroids are released in the blood, influence in the other tissues is avoided...

We present a case of female dyspareunia secondary to metalware placement during extensive pelvic surgery following a motor vehicle accident. The patient initially had an uneventful recovery from her operations. However, she noticed pain with vaginal intercourse, due to a screw tip which was palpable on vaginal examination. X-ray imaging confirmed long screws in the medial part of an anterior column plate, which were impacting on the anterior vaginal wall. Subsequent percutaneous removal of two screws resulted in resolution of her symptoms of painful vaginal intercourse...

Congenital absence of the uterus and vagina (CAUV) is the most extreme female Müllerian duct abnormality. Several researches proposed that genetic factors contributed to this disorder, whereas the precise genetic mechanism is far from full elucidation. Here, utilizing whole-exome sequencing (WES), we identified one novel missense mutation in LHX1 (NM_005568: c.G1108A, p.A370T) in one of ten unrelated patients diagnosed with CAUV. This mutation was absent from public databases and our internal database. Through the luciferase reporter analysis, we found that the mutation could change the transcriptional activity of LHX1 and its effect on the regulation of the downstream target gene GSC, which might be associated with urogenital system development...

INTRODUCTION: Recurrent vulvovaginal candidiasis is defined as having three to four episodes per year and causes substantial suffering. Little is known about the mechanisms leading to relapses in otherwise healthy women. Nitric oxide is part of the nonspecific host defense and is increased during inflammation. Nitric oxide levels were measured and the expression of inducible nitric oxide synthase was analyzed in the vagina during an acute episode of recurrent vulvovaginal candidiasis and after treatment with fluconazole...

Depot-medroxyprogesterone acetate is a commonly used injectable contraceptive that has been associated with an increased risk of HIV acquisition. This study compares effects of depot-medroxyprogesterone acetate on immune parameters from several upper reproductive tract compartments relevant to HIV-1 susceptibility in repetitive samples from 15 depot-medroxyprogesterone acetate users and 27 women not on hormonal contraceptives. Compared with samples from unexposed women in the mid-luteal phase, depot-medroxyprogesterone acetate use was associated with: increased endocervical concentrations of MCP1 and IFNalpha2; decreased endocervical concentrations of IL1beta and IL6; increased proportions of endometrial CD4+ and CD8+ cells expressing the activation marker HLADR; increased density of endometrial macrophages; and decreased density of endometrial regulatory T cells...

BACKGROUND: The development of antivirals against herpes simplex virus 2 (HSV-2) has a major public health importance because of the wide spectrum of associated clinical disease in both immunocompetent and immunocompromised populations. Even with the extensive use of acyclovir, issues such as emergence of drug resistant strains, poor oral bioavailability, and low effectiveness in recurrent infections have highlighted the requirement for alternate therapies. Plants, which are rich in metabolites and active against viruses, are being explored as one such source...
