Background: Although to date the pathogenesis of endometriosis remains largely unexplained, it is known that processes of migration, proliferation and revascularization and thus calcium as a messenger substance play an important role. Consecutively, the present study examines the immunohistochemical expression of the calcium transient receptor potential channels 3 and 6 (TRPC3 and TRPC6) in ectopically located (outside the uterine cavity) endometrial tissue.
Methods: Laparoscopically collected and histomorphologically verified endometriosis tissues from several different intraabdominal locations were examined (n = 20) and immunohistochemical stainings were performed with anti-TRPC3 and anti-TRPC6 antibodies (Alomone Labs, Jerusalem).
Background: Serum bone turnover markers might play a role in the prediction of the development of bone metastases in breast cancer (BC) patients. We conducted a retrospective cohort study to address the association of serum bone turnover markers with oncologic outcomes.
Methods: We included 80 women with BC, who were operated on at the Department of Gynecology, Obstetrics and Reproductive Medicine, Homburg/Saar, Germany.
Purpose: To investigate the role of Dkk1 as a predictor of response to NACT in BC patients.
Methods: This retrospective monocentric study included 145 women who had undergone NACT followed by breast surgery. Dkk1 protein expression was assessed using immunohistochemistry staining in core needle biopsies and mammary carcinoma specimens.
Objective: To assess differences in obstetric practices between Syrian war refugees (SRs) and non-Syrian nonrefugees (NSRs) in a tertiary care provider in Germany.
Methods: This was a retrospective study of SRs (n = 356) and NSRs (n = 5836) giving birth between January 2015 and December 2018. Data on medical history, birth mode, complications, and neonatal parameters was extracted.
The goal of this study was to examine how regular physical activity before and during pregnancy affected life quality throughout pregnancy. Between July 2020 and May 2021, 218 pregnant women were recruited from 11 outpatient clinics for this survey. Data were collected prospectively in a panel format beginning with the 10th gestational week over a 20-week period.

Response to NACT is an important parameter predictive of oncological outcomes (progression-free and overall survival). An approach to the evaluation of predictive markers enabling therapy individualization is the identification of tumor driver genetic mutations.

As of today, histologic examination of the uterus after hysterectomy constitutes the gold standard for diagnosis. The aim of this study was to determine the validity of sonographic, hysteroscopic, and laparoscopic criteria for the diagnosis of the disease.

About 70% of these cancers are diagnosed in advanced stages (FIGO IIB-IV), with a 5-year survival rate of 20-30%. Due to the poor prognosis of this disease, research has focused on its pathogenesis and the identification of prognostic factors.

According to the Embryo Protection Act, the selection of embryos with the greatest potential for successful implantation in Germany must be performed in the pronucleus stage. The main aim of this study was to identify morphokinetic parameters that could serve as noninvasive biomarkers of blastocyst quality in countries with restrictive reproductive medicine laws. The sample comprised 191 embryos from 40 patients undergoing antagonist cycles for intracytoplasmic sperm injection.

The performance of three specific monoclonal antibodies in a head-to-head comparison is unknown. In addition, a potential correlation of PD-L1 expression and clinico-pathological parameters has not been investigated.

Although the literature confirms the hypothesis that particular nutritional factors can influence the quality of semen, until today, there are no specific dietary recommendations created for infertile males. Since the male contribution to the fertility of a couple is crucial, it is of high importance to determine the dietary factors that can affect male fertility.

Material And Methods: Tumor specimens of 60 patients with histologically confirmed TNBC were retrospectively analyzed. Formalin-fixed paraffin-embedded blocks of the tumor tissue were used to prepare tissue microarrays (TMAs).

Purpose: To investigate the interaction between Wnt/β-catenin and estrogen signaling pathways in endometrial cancer (EC).
Methods: 119 women were involved in this study, including 65 women with histologically confirmed EC and 54 healthy women as a control group. Serum protein levels of Dkk1 were measured using ELISA.
Background: Prenatal measurement of placental biomarkers was able to improve screening and diagnosis of preeclampsia. Little is known about the clinical role of placental biomarkers in the postpartum period.
Methods: This study is a prospective monocentric trial that included a total of 30 women with preeclamptic pregnancies.
Purpose: In previous studies, we have shown that SEC62 has an essential function in cell migration, epithelial-to-mesenchymal transition, and endoplasmic reticulum stress tolerance of cancer cells. SEC62 expression correlated with distant and lymph node metastasis and poor outcome in different cancer entities. In this initial study, we investigated SEC62 expression and its possible role as a prognostic and predictive biomarker in breast cancer (BC).

Objectives: We investigated the effect of umbilical cord blood mononuclear cells (MNCs) in a new double-hit mouse model of BPD.
Despite increased survival of very preterm newborns, bronchopulmonary dysplasia (BPD) remains a major threat, as it affects long-term pulmonary function and neurodevelopmental outcome. Recent research focused on mechanisms of lung repair. Animal models of BPD in term rodents use postnatal hyperoxia in order to mimic features observed in very preterm human neonates: reduced alveolarization and impaired septal architecture without profound inflammatory changes.

Objective: We investigated total folate, tetrahydrofolate (THF), 5-methyltetrahydrofolate (5-MTHF), formyl-THF, 5,10-methenylTHF, and folic acid concentrations in women and in umbilical cord blood at delivery.
Design: The study included 87 pregnant women and 29 cord blood samples, including 24 mother-infant pairs.
Folate deficiency can cause age-related disease. Folic acid (FA) has been used in studies aiming at disease prevention. Recently, unmetabolized FA in plasma raised public health concerns; but numerous studies used FA for disease prevention.
