Endometritis is one of the major problems in the horse breeding industry. The use of antibiotics for treatment of endometritis in the mare is recommended as best practice. The intrauterine application of antibiotics, however, has been under discussion over the last years because of concerns about its efficacy. The systemic use of antibiotics has been considered more effective because of its better distribution within the uterus. The objective of the present study was to determine the concentration of ceftiofur derivates in serum and endometrial tissue after intramuscular administration. Specifically, the authors tested the hypothesis that ceftiofur concentrations in serum and endometrial tissue remain above the minimum inhibitory concentration (MIC) for common uterine pathogens for 24 h. Nine mares in estrus received a single dose of 2.2 mg/kg ceftiofur hydrochloride intramuscular per kg of body weight. Blood samples and endometrial tissue were obtained immediately before treatment (-1 h) and 2 h and 24 h after treatment. Endometrial tissue was collected with a Kevorkian biopsy punch. Additional blood samples were collected 4 h and 10 h after treatment from the jugular veins. For determination of ceftiofur derivates in serum and endometrial tissue a high performance liquid chromatography (HPLC) assay was used. Results in serum and uterine tissue revealed greatest concentration of ceftiofur at 2 h and lowest concentrations at 24 h after treatment. Concentrations of ceftiofur at 2 and 24 h after treatment were significantly greater in serum than in endometrial tissue, but remained above the reported MIC for Streptococcus equi zooepidemicus and Escherichia coli in both serum and endometrial tissue until 24 h after treatment.

Intrauterine growth restriction (IUGR) is a common condition in swine associated with high piglet mortality and morbidity that develops in early gestation. This review article explores differences in uterine and placental tissues associated with IUGR fetuses compared to their normally-grown littermates at different stages of gestation. Specifically, we will review the available knowledge to date describing differences in 1) structure, 2) cellular apoptosis and proliferation, 3) adhesion, and 4) angiogenesis in endometrial and placental tissues associated with IUGR fetuses across gestation.

: Endometriosis is a chronic gynecological disorder characterized by ectopic endometrial-like tissue. The symptoms of this disease negatively affect the patient's quality of life, both physically and mentally. This study aims to identify key factors impacting health-related quality of life in endometriosis patients.

The dynamic nature of human endometrial tissue presents unique challenges in analysis. Despite extensive research into endometrial disorders such as endometriosis and infertility, recent systematic reviews have highlighted concerning issues with the reproducibility of omics studies attempting to identify biomarkers. This review examines factors contributing to poor reproducibility in endometrial omics research.

Endometriosis is a widely spread disease that affects about 8% of the world's female population. This condition may be described as a spread of endometrial tissue apart from the uterine cavity, but this process's pathomechanism is still unsure. Apart from classic endometriosis symptoms, which are pelvic pain, infertility, and bleeding problems, there are neuropsychiatric comorbidities that are usually difficult to diagnose.

Sentinel lymph node (SLN) detection has been widely investigated in recent years as a part of the surgical staging of women with endometrial cancer (EC), gradually overtaking lymphadenectomy (LND) in this respect. In this study, thirty EC patients, assumed as stage I, were investigated using superparamagnetic iron oxide (SPIO) as a tracer for SLN detection followed by LND. The endpoints of this research were the proportion of successful SLN detection, the average number of SLNs per patient, the percentage of bilaterally detected SLNs, and the proportion of metastatic SLNs.
