Sedentary behaviors negatively related to depressive symptoms in college students:The roles of type and duration of sedentary behaviors.

Objective: This study aimed to examine the associations between different types and duration of sedentary behaviors and depressive symptoms among college students.

Methods: A cross-sectional study was conducted at a university in Shanghai, China, utilizing convenience sampling to recruit 3,190 participants (mean age 20.06 ± 1.

A gamma-ray imaging method for multiple radionuclides and low-activity radioactive sources.

Gamma-ray coded-aperture imaging technology has important applications in the fields of nuclear security, isolated source detection, and the decommissioning of nuclear facilities. However, artifacts can reduce the quality of reconstructed images and affect the identification of the intensity and location of radioactive sources. In this paper, a gamma-ray coded-aperture imaging method based on primitive and reversed coded functions (PRCF) was proposed to reduce imaging artifacts.

Multiple attention channels aggregated network for multimodal medical image fusion.

Background: In clinical practices, doctors usually need to synthesize several single-modality medical images for diagnosis, which is a time-consuming and costly process. With this background, multimodal medical image fusion (MMIF) techniques have emerged to synthesize medical images of different modalities, providing a comprehensive and objective interpretation of the lesion.

Purpose: Although existing MMIF approaches have shown promising results, they often overlook the importance of multiscale feature diversity and attention interaction, which are essential for superior visual outcomes.

Hydrogen Bonding Polarization Strengthening the Peptide-Based Hydrogels.

Peptide-based hydrogels form a kind of promising material broadly used in biomedicine and biotechnology. However, the correlation between their hydrogen bonding dynamics and mechanical properties remains uncertain. In this study, we found that the adoption of β-sheet and α-helix secondary structures by ECF-5 and GFF-5 peptides, respectively, could further form fiber networks to immobilize water molecules into hydrogels.

Safety and Effectiveness of Glucagon-like Peptide-1 Receptor Agonists in Inflammatory Bowel Disease.

Introduction: The safety and effectiveness of glucagon-like peptide receptor agonists (GLP1-RA) in patients with inflammatory bowel disease (IBD) are poorly understood.

Methods: Patients with IBD treated with GLP1-RA were retrospectively identified for outcomes of adverse events, weight change, and clinical, endoscopic, and biomarker response.

Results: Among a total of 120 patients with IBD, gastrointestinal side effects being the most common (11.
