High correlation between Ki-67 expression and a novel perfusion MRI biomarker diffusion-derived vessel density (DDVD) in endometrial carcinoma.

Objective: This study aimed to investigate the feasibility of diffusion-derived vessel density (DDVD) in characterizing tumor microvasculature in endometrial carcinoma (EC), and to explore the correlations with Ki-67 proliferation status and histological type based on DDVD values.

Methods: There were in total 81 EC patients. There were 64 cases of non-aggressive histological type, and 17 cases of aggressive histological type.

Gene Doping Detection From the Perspective of 3D Genome.

Since the early 20th century, the concept of doping was first introduced. To achieve better athletic performance, chemical substances were used. By the mid-20th century, it became gradually recognized that the illegal use of doping substances can seriously endangered athletes' health and compromised the fairness of sports competitions.

Appraising the Effects of Gut Microbiota on Insomnia Risk Through Genetic Causal Analysis.

BackgroundInsomnia is a common neurological disorder that exhibits connections with the gut microbiota; however, the exact causal relationship remains unclear. MethodsWe conducted a Mendelian randomization (MR) study to systematically evaluate the causal effects of genus-level gut microbiota on insomnia risk in individuals of European ancestry. Summary-level datasets on gut microbiota were sourced from the genome-wide association study (GWAS) of MiBioGen, while datasets on insomnia were obtained from the GWAS of Neale Lab and FinnGen.

Quantitative analysis of choroidal vascular structures and anatomical changes in pachychoroid spectrum diseases using ultra-widefield SS-OCTA.

This study used ultra-widefield swept-source optical coherence tomography angiography (UWF SS-OCTA) to analyze and compare choroidal blood flow and anatomical changes in eyes affected by central serous chorioretinopathy (CSC), pachychoroid neovasculopathy (PNV), and uncomplicated pachychoroid (UCP). The findings revealed distribution patterns of vortex veins across the three patient groups and provided initial findings insights into the origin of choroidal neovascularization (CNV) in PNV. A total of 44 patients with CSC, 38 with PNV, and 46 with UCP were included in the analysis.

Virtual Frisch grid perovskite CsPbBr semiconductor with 2.2-centimeter thickness for high energy resolution gamma-ray spectrometer.

High intrinsic detection efficiency is as decisive as high energy resolution. Scaling up detector volume has presented great challenges, preventing perovskite semiconductors from reaching sufficient detection efficiency. We report a hole-only virtual-Frisch-grid CsPbBr detector up to 2.
