Moderating effects of screen time on the relationship between family functioning and negative emotions in Chinese children with cancer.

Purpose: To explore whether screen time moderates the relationship between family functioning and negative emotions in Chinese children with cancer.

Methods: Between November 2023 and May 2024, 206 children with cancer were recruited from a pediatric oncology ward at a tertiary hospital. Negative emotions, family functioning, and screen time were assessed using the Depression Anxiety Stress Scale-21, Family Adaptability and Cohesion Evaluation Scales, Second Edition, Chinese Version, and Screen Time Questionnaire, respectively.

Effect of adaptive statistical iterative reconstruction-V algorithm and deep learning image reconstruction algorithm on image quality and emphysema quantification in COPD patients under ultra-low-dose conditions.

Purpose: To explore the effect of different reconstruction algorithms (ASIR-V and DLIR) on image quality and emphysema quantification in chronic obstructive pulmonary disease (COPD) patients under ultra-low-dose scanning conditions.

Materials And Methods: This prospective study with patient consent included 62 COPD patients. Patients were examined by pulmonary function test (PFT), standard-dose CT (SDCT) and ultra-low-dose CT (ULDCT).

A Series of Novel Alleles of Modulating Heading and Salt Tolerance in Rice.

Rice ( L.) is a staple crop for nearly half of the global population and one of China's most extensively cultivated cereals. Heading date, a critical agronomic trait, determines the regional and seasonal adaptability of rice varieties.

Can strengthening digital infrastructure enhance productivity in the cultural industry? evidence from Tibet.

This study, grounded in the Total Factor Productivity (TFP) theoretical framework, examines the impact of digital infrastructure on the productivity of Tibet's cultural industry from 2011 to 2021. It aims to uncover how the innovative allocation of production factors can enhance new-quality productivity. The core aspect of new-quality productivity is the improvement of TFP, with digital infrastructure promoting the cultural industry's development by optimizing industrial agglomeration, improving logistics efficiency, and reducing the urban-rural consumption gap.

The mitochondrial functional characteristics and microstructure play an important role in yak meat color during wet curing.

The study investigated the impact of low-dose sodium nitrite on yak meat color and mitochondrial functional characteristics during the wet curing. The results showed that sodium nitrite significantly enhanced the redness ( value) of yak meat by increasing the activities of mitochondrial complexes I, II, III and IV, which are critical for electron transport and aerobic respiration. Additionally, sodium nitrite reduced mitochondrial swelling and membrane permeability, and slowed the production of lipid oxidation products, indicating protective effects against mitochondrial damage and preserving mitochondrial integrity.
