Recently, virtual staining techniques have attracted more and more attention, which can help bypass the chemical staining process of traditional histopathological examination, saving time and resources. Meanwhile, as an emerging tool to characterize specific tissue structures in a label-free manner, the Mueller matrix microscopy can supplement more structural information that may not be apparent in bright-field images. In this Letter, we propose the Mueller matrix guided generative adversarial networks (MMG-GAN).

A Mueller matrix covers all the polarization information of the measured sample, however the combination of its 16 elements is sometimes not intuitive enough to describe and identify the key characteristics of polarization changes. Within the Poincaré sphere system, this study achieves a spatial representation of the Mueller matrix: the Global-Polarization Stokes Ellipsoid (GPSE). With the help of Monte Carlo simulations combined with anisotropic tissue models, three basic characteristic parameters of GPSE are proposed and explained, where the V parameter represents polarization maintenance ability, and the E and D parameters represent the degree of anisotropy.

Related studies have pointed out that Killer immunoglobulin-like receptor 2DL4 (KIR2DL4) was associated with vascular remodeling in early pregnancy, and it might play an important role in immunity. In this study, recurrent implantation failure (RIF)-related GSE58144 dataset was extracted from the Gene Expression Omnibus (GEO) database. Firstly, the immune micro-environment analyses were conducted to analyze the pathogenesis of KIR2DL4 in RIF.

Article Synopsis
  • The study investigates the role of uterine natural killer (uNK) cells in women experiencing recurrent implantation failure (RIF) compared to a control group.
  • Results showed a significant decrease in stage 4 uNK cells and an increase in stage 6 uNK cells in women with RIF, along with a positive correlation between IL-15 mRNA levels and the presence of CD56+ uNK cells.
  • The findings suggest that a deficiency in IL-15 may lead to a reduction of stage 4 uNK cells, potentially contributing to difficulties in implantation for women with RIF.

Article Synopsis
  • This study aimed to create a diagnostic model using clinical and MRI radiomics features for detecting chronic cholangitis in children with pancreaticobiliary maljunction (PBM).
  • A total of 144 subjects' clinical characteristics and MRI features were analyzed, and a radiomics score was calculated to develop a combined model.
  • The combined model outperformed the clinical model alone in predictive accuracy, demonstrating significant potential for improving diagnosis in affected children.

Article Synopsis
  • The study aims to develop and validate a nomogram using MR-based radiomics and clinical factors to diagnose liver fibrosis in children with pancreaticobiliary maljunction (PBM), enhancing clinical decision-making and outcomes.
  • A total of 136 PBM patients from two centers were analyzed, with data divided into training and validation sets for accurate assessment of liver fibrosis determined via histopathological examination.
  • The results indicated that two clinical factors and four radiomics features effectively predicted liver fibrosis, with the nomogram demonstrating strong performance across different validation sets, showing clinical promise for patient management.

Article Synopsis
  • The purpose of the study was to create a model that identifies risk factors and predicts acute pancreatitis in children with pancreaticobiliary maljunction (PBM).
  • The researchers used machine learning techniques, dividing their patient data into training and validation sets to compare the effectiveness of three models: logistic regression, support vector machine, and extreme gradient boosting.
  • The findings revealed that both XGBoost and SVM models performed similarly well (AUC around 0.814), outperforming the logistic regression model, and identified age, protein plugs, and white blood cell count as key predictors of acute pancreatitis.

Introduction: The present study aimed to clarify the underlying mechanism of metformin (met) in the management of polycystic ovary syndrome (PCOS) and to explore the role of the UCA1/microRNA-18a signaling pathway in the control of PCOS.

Material And Methods: Real-time PCR was performed to compare the levels of irisin, blood glucose, UCA1 and miR-18a among PCOS, PCOS + Met, and control groups using area under curve (AUC) values. In-silicon analysis and luciferase assay were performed to explore the regulatory relationship among UCA1, miR-18a and irisin.

Dexmedetomidine and propofol are commonly used sedative agents in pediatric patients undergoing magnetic resonance imaging (MRI). The present meta-analysis aimed to compare dexmedetomidine with propofol in pediatric patients undergoing MRI using trial sequential analysis (TSA). The PubMed, Cochrane Library and Web of Knowledge databases were systematically searched for entries up to August 2018 for potential randomized controlled trials comparing dexmedetomidine with propofol in pediatric patients undergoing MRI.

Background: Magnetic resonance imaging (MRI) is often used in children for its clear display of body parts. But it is usually hard to acquire high-quality images, for the uncooperative ability of children. It is believed that pre-MRI training could ensure the high quality of images.

Correlation between computed tomography (CT) signs, lymphatic metastasis and pathological features of neuroblastoma (NB) in children was investigated. A total of 374 child patients diagnosed with NB via CT scan and pathological section in Department of Pediatric of Xuzhou Children's Hospital from March 2011 to January 2017 were collected, and their clinical data were retrospectively analyzed. According to CT signs, NB calcification and invasion to surrounding tissues were evaluated, and the tumor site, tumor size, lymphatic metastasis, pathological types and clinical prognosis were analyzed.

  • - The study aimed to investigate how glycosides from Tripterygium wilfordii (GTW) affect genes related to testicular reproduction in male mice and the potential benefits of kidney-tonifying Chinese herbs.
  • - Mice were treated with GTW to induce reproductive dysfunction, then various groups received different combinations of saline, GTW, and Chinese herbs (Cistanche and Rehmannia) for three weeks to assess changes in gene expression.
  • - Results showed that GTW reduced the expression of certain reproductive genes and increased apoptosis-related genes; however, the Chinese herbs improved reproductive functions, especially when used together.
