AI Article Synopsis
- The study investigates the role of clusterin, a multifunctional protein, in normal and preeclamptic placental tissues, particularly its expression and localization.
- Clusterin was found to be predominantly located in specific cells within the placenta and its levels were significantly higher in preeclamptic tissues compared to normal ones.
- The findings suggest that elevated clusterin may be involved in the mechanisms underlying preeclampsia, indicating its potential significance in this condition.
Article Abstract
Aim: Clusterin is a multifunctional protein that is up-regulated during many different pathophysiological states. Clusterin may be related to a compensation mechanism involving aggregation of soluble proteins, inhibition of complement-mediated cell damage, adaptive regeneration or apoptosis. Clusterin may increase in response to cell damage that results from hypoxic stress in the preeclamptic placenta. The goal of this study was to measure clusterin expression and localization in normal and preeclamptic placental tissues.
Methods: Immnunohistochemical and double immunofluorescent staining for clusterin was performed on eight normal and eight preeclamptic placental tissues, and clusterin expression was quantified by Western blotting.
Results: Immunohistochemical analysis of clusterin in placental tissues obtained from normal pregnancies and those with preeclampsia showed localization of clusterin mainly in the syncytiotrophoblasts and villous endothelial cells. In the double immunofluorescent staining, clusterin was detected in the cytoplasm. The Western blot analysis showed that clusterin expression in the placental tissues of the preeclampsia group was significantly higher than in the normal pregnancy group.
Conclusions: Increased expression of clusterin in placental tissues might play an important role in the pathogenesis of preeclampsia.

Purpose: The aim of the present study was to establish a SYBR Green-based real-time PCR assay for detection of the Nc5 segment from the Neospora caninum genome.
Methods: The oligonucleotides sequences targeting the Nc5 gene previously reported and designed in-house were validated. Two Primer sets were evaluated and tested in four different combinations.

Pathological analysis of placenta is currently a valuable tool for gaining insights into pregnancy outcomes. In placental histopathology, multiple functional tissues can be inspected as potential signals reflecting the transfer functionality between fetal and maternal circulations. However, the identification of multiple functional tissues is challenging due to (1) severe heterogeneity in texture, size and shape, (2) distribution across different scales and (3) the need for comprehensive assessment at the whole slide image (WSI) level.

Background: Pre-eclampsia (PE) poses a significant threat to mothers and infants worldwide. Studies indicate that taking low-dose aspirin before the 16th week of pregnancy may prevent approximately 70 % of PE cases, highlighting the importance of predicting PE. Cell-free RNA (cf-RNA) exhibits significant changes in the maternal peripheral blood during early pregnancy, making cf-RNA analysis a promising and less invasive method for predicting PE.

Autism spectrum disorders encompass diverse neurodevelopmental conditions marked by alterations in social communication and repetitive behaviors. Advanced maternal age is associated with an increased risk of bearing children affected by autism but the etiological factors underlying this association are not well known. Here, we investigated the effects of advanced maternal age on offspring health and behavior in two genetically divergent mouse strains: the BTBR T Itpr3/J (BTBR) mouse model of idiopathic autism, and the C57BL/6 J (B6) control strain, as a model of genetic variability.
