Splenomegaly is a quite common clinical feature of Philadelphia (Ph) negative chronic myeloproliferative neoplasms (MPNs) and its presence may, in some cases, drives treatment decision. Most importantly, palpable splenomegaly is a minor criterion for both pre-fibrotic/early primary myelofibrosis and primary myelofibrosis (PMF) diagnosis, even if clinical assessment by physical examination is poorly reliable and accurate. On the other hand, despite the International Working Group-Myeloproliferative Neoplasms Research and Treatment and European LeukemiaNet guidelines defined spleen response criteria by palpation, they also recognized the highly subjective nature of spleen size assessment by physical examination, and recommended objective confirmation of volume reduction via computed tomography or magnetic resonance imaging (MRI).

The covariance index method, the idiosyncratic item response method, and the machine learning method are the three primary response-pattern-based (RPB) approaches to detect faking on personality tests. However, less is known about how their performance is affected by different practical factors (e.g.

This study reports a novel ratiometric fluorescence sensor based on a tetraphenylethylene-bipyridine covalent organic framework (TPE-Bpy-COF) for the sensitive detection of Cu, leveraging the unique coordination properties of the bipyridine moieties. The interaction between Cu and the nitrogen atoms in the bipyridine units induces fluorescence quenching at 500 nm through an efficient host-guest electron transfer mechanism, where excited-state electrons from the COF framework are transferred to the vacant orbitals of Cu. Upon excitation at 410 nm, the sensor exhibits a primary emission peak at 500 nm, which is quenched in the presence of Cu, while an overtone peak at 820 nm remains stable, serving as an internal reference for ratiometric measurements and significantly enhancing the accuracy and reliability of the sensor.

Introduction: This article explores the impact of innovation on urban public health, with a particular focus on panel data from 15 sub-provincial cities in China. The study aims to provide scientific evidence for policymakers by analyzing how technological innovation affects urban public health levels.
Methods: The study used a panel model for empirical analysis which based on panel data from 15 sub provincial cities across the country, using the number of doctors per 10,000 people and per capita financial medical and health expenditure as proxy variables for urban public health, and using the level of technological development as the core explanatory variable for regression analysis.
Influence of sedentary behavior on sleep quality in postmenopausal women in high-altitude regions of China: a cross-sectional study.
Front Neurol
January 2025
Graduate Development Office, Harbin Sport University, Harbin, China.
Objective: This study investigates the association between sedentary behavior and sleep quality among postmenopausal women residing in China's plateau regions. Particular attention is given to moderating effects of age, body mass index (BMI), and sleep environment. This study aims to identify modifiable risk factors influencing sleep quality in this high-altitude population.
