Objectives: This study was conducted to investigate the modulatory role of an ethanol extract of beans on heat shock protein 90 (HSP90) and asymmetric dimethylarginine (ADMA) levels of endothelial cells under the influence of plasma of pre-eclamptic patients.
Methods: The endothelial cells were obtained from a human umbilicus. In the confluent phase, the cells were subdivided into groups: the control group (no treatment), the endothelial cell group that was exposed to 2% pre-eclamptic patients' plasma, and the endothelial cell group that was exposed to 2% pre-eclamptic patients' plasma and treated with the ethanol extract of at various doses (25, 50, or 100 ppm). Analysis of HSP90 levels was carried out by an enzyme-linked immunosorbent assay. Quantification of ADMA was conducted by immunocytochemistry.
Results: There was a decreased HSP90 level in the group exposed to the pre-eclamptic patients' plasma. This decrease was significantly attenuated by the extract of at the doses of 50 and 100 ppm. The pre-eclamptic patients' plasma significantly increased ADMA level as compared with the control group. This increase was significantly attenuated by the administration of the extract at the two highest doses.
Conclusions: The extract of beans protected the endothelial cells that were exposed to pre-eclamptic patients' plasma by increasing HSP90 levels and reducing ADMA levels.

Pre-eclampsia (PE) is a serious condition affecting 2-8% of pregnancies worldwide, leading to high maternal and fetal morbidity and mortality. MicroRNAs (miRNAs), small non-coding RNA molecules, have emerged as potential biomarkers for various pregnancy-related pathologies, including PE. MiRNAs in plasma and serum have been extensively studied, but urinary miRNAs remain underexplored, especially during early pregnancy.

Background: Pre-eclampsia has long been proven to be an independent risk factor for postpartum depression (PPD). Excessive increase in body mass index (BMI) during pregnancy is an important factor inducing pre-eclampsia. Increased blood pressure is the main symptom of patients with pre-eclampsia.

Background: With the advancement in embryology and the introduction of time-lapse monitoring system, the embryologists' goal might be to find not only the embryo with the highest probability of live birth, but also the embryo with the highest probability to progress to a healthy full-term delivery. Thus, we aimed to investigate the association between morphokinetic time-lapse parameters and obstetrical and perinatal complications.
Methods: A cohort study reviewing fertility and delivery files of all singletone births from IVF patients whose embryos were cultured in a time-lapse monitoring system and had a single fresh embryo transfer at our center between 2013-2019.

Computational models can be at the basis of new powerful technologies for studying and classifying disorders like pre-eclampsia, where it is difficult to distinguish pre-eclamptic patients from non-pre-eclamptic based on pressure when patients have a track record of hypertension. Computational models now enable a detailed analysis of how pregnancy affects the cardiovascular system. Therefore, new non-invasive biomarkers were developed that can aid the classification of pre-eclampsia through the integration of six different measured non-invasive cardiovascular signals.

: Pre-eclampsia (PE) is a pregnancy-specific condition characterized by significant health risks for pregnant women worldwide due to its status as a multi-organ disorder. High blood pressure (hypertension) with or without proteinuria is usually considered an initial clinical sign of PE. The pathogenesis of pre-eclampsia is highly complex and likely involves multiple factors, including poorly developed uterine spiral arterioles, immunological issues, placental ischemia or infarction, and genetic abnormalities.
