Deep learning enables robust assessment and selection of human blastocysts after in vitro fertilization
2019
AbstractVisual morphology assessment is routinely used for evaluating of embryo quality and selecting human blastocysts for transfer after in vitro fertilization (IVF). However, the assessment produces different results between embryologists and as a result, the success rate of IVF remains low. To overcome uncertainties in embryo quality, multiple embryos are often implanted resulting in undesired multiple pregnancies and complications. Unlike in other imaging fields, human embryology and IVF have not yet leveraged artificial intelligence (AI) for unbiased, automated embryo assessment. We postulated that an AI approach trained on thousands of embryos can reliably predict embryo quality with…
Metagenomic Analysis of Milk of Healthy and Mastitis-Suffering Women.
2015
Background: Some studies have been conducted to assess the composition of the bacterial communities inhabiting human milk, but they did not evaluate the presence of other microorganisms, such as fungi, archaea, protozoa, or viruses. Objective: This study aimed to compare the metagenome of human milk samples provided by healthy and mastitis-suffering women. Methods: DNA was isolated from human milk samples collected from 10 healthy women and 10 women with symptoms of lactational mastitis. Shotgun libraries from total extracted DNA were constructed and the libraries were sequenced by 454 pyrosequencing. Results: The amount of human DNA sequences was ≥ 90% in all the samples. Among the bacteri…
Body image during sexual activity in the population of Polish adult women
2020
Introduction. Recently it has been shown that body image during sexual activities is a better predictor of the diversity of sexual experience than body image as a psychological trait. To measure contextual body image (as a state) the Body Exposure During Sexual Activity Questionnaire (BESAQ) was developed. Material and methods. 845 women aged 18-55 years were included in the study. The original model was first translated into Polish and consulted to create the version to be further validated. The original model was tested using confirmatory factor analysis (CFA). The population was divided in two equal groups – group 1 was used for exploratory factor analysis. Discriminant and convergent va…
Sexual behaviors and function during menopausal transition—does menopausal hormonal therapy play a role?
2020
Objectives: The menopausal transition is a biological adaptation to the variety of life changes (body, comorbidities, relationship), but that biology is not an “end all” in the context of sexual function and overall sexual health. The aim of this study is to evaluate determinants altering the risk of female sexual dysfunction (FSD) and other sexual problems and to establish whether menopausal hormonal therapy (MHT) decreases that risk and modifies sexual behaviors. Methods: A cross-sectional observational study was conducted in 210 women between the ages of 45 and 55. Two groups were identified: MHT users (n = 107) and controls—MHT non-users (n = 103). Diagnostic and Statistical Manual of M…

Enzym-histochemische Studien am cervicalen Dr�senfeld des Uterus
1972
Durch enzym-histochemische Untersuchungen an Cervices soll Einblick in den Stoffwechsel des cervicalen Drusenfeldes gewonnen werden. Hierfur wurden insbesondere die Enzyme des Glucosestoffwechsels, der Fettsaureoxydation, des Pentosephosphatstoffwechsels, des Citronensaurecyclus sowie des NADH- und NADPH-Diaphorese-Systems und des Aminosaurestoffwechsels untersucht. Die einheitliche Nachweistechnik erlaubt in Form eines Art Screening-Tests eine Information uber die vorhandenen Aktivitaten der einzelnen Enzyme, wobei — abgesehen von einem Enzym des Glucosestoffwechsels, namlich der Alkoholdehydrogenase und des Aminosaurestoffwechsels, der Glutamatdehydrogenase — alle Fermente nachgewiesen we…

Phosphatasen in der Placenta und ihren einzelnen Zellfraktionen
1956
In der menschlichen Placentazelle wurde die intracellulare Verteilung der Phosphataseaktivitat bei pH 5,6 und pH 9,8 untersucht. Von der im Gewebe vorhandenen Fermentaktivitat (saure bzw. alkalische Phosphatase) entfallen 82 bzw. 92% auf die Fraktion der Mikrosomen + Cytoplasma, 11 bzw. 7% auf die Mitochondrien und nur 3 bzw. 2% auf die Zellkerne. Die hochste spezifische Aktivitat weisen die Mitochondrien auf. Diese kann durch vorherige Behandlung des Gewebes (Extraktion mit H2O, Stehenlassen bei Zimmertemperatur, Einfrieren und Auftauen) um das 1 1/2–2fache gesteigert werden. Es folgen in absteigender Reihenfolge das Cytoplasma + Mikrosomen und der Zellkern. Die Aktivitat im mutterlichen u…
