Novel Co-MOF-doped gelatin/agar intelligent film for beef freshness visual tracking based on the structural change of ZIF-67 under ammonia etching effect.

It is an important task to construct intelligent packaging for meat freshness monitoring with good color stability and indication function. Herein, cobalt-based metal-organic framework nanomaterials (Co-MOF, ZIF-67) with antimicrobial and ammonia-sensitive properties were successfully synthesized and added into gelatin/agar (GA) matrix to develop highly stable intelligent films (GA/ZIF67). The incorporation of ZIF-67 nanoparticles enhanced the hydrophobicity (water contact angle >90°) and UV-blocking properties (close to 0.

Comparison of differences in transcriptional and genetic profiles between intra-central nervous system and extra-central nervous system large B-cell lymphoma.

Primary central nervous system diffused large B-cell lymphoma (PCNS-DLBCL) is a rare type of non-Hodgkin lymphoma restricted to the central nervous system (CNS). To explore its specific pathogenesis and therapeutic targets, we performed multi-omics sequencing on tumor samples from patients diagnosed with PCNS-DLBCL, secondary CNS-DLBCL or extracranial (ec) DLBCL.By single-cell RNA sequencing, highly proliferated and dark zone (DZ)-related B cell subclusters, MKI67_B1, PTTG1_B2 and BTG1_B3, were predominant significantly in PCNS-DLBCL.

[Value of exercise challenge testing in the diagnosis of cough variant asthma in children].

Objectives: To investigate the value of exercise challenge testing (ECT) in the diagnosis of cough variant asthma (CVA) in children.

Methods: A prospective study was conducted on 78 children with chronic cough who were admitted between January 2023 and January 2024. ECT was performed, and clinical data were collected.

Comparative Analysis of Central and Noncentral Degenerative Mitral Regurgitation Treated With Transcatheter Mitral Valve Edge-To-Edge Repair.

Background: Mitral valve transcatheter edge-to-edge repair (M-TEER) was initially indicated for central degenerative mitral regurgitation (DMR) lesions, but advancements in technology have enabled successful treatment in an increasing number of noncentral DMR patients.

Aims: This study aims to compare procedural outcomes and prognosis between noncentral DMR patients, outside clinical trial anatomical criteria, and central DMR patients undergoing M-TEER.

Methods: Drug-refractory moderate-to-severe DMR patients treated with M-TEER at Fuwai Hospital from January 2021 to February 2024 were retrospectively analyzed.

An Integrative Analysis of the Transcriptome and Proteome of Rice Grain Chalkiness Formation Under High Temperature.

Exposure to high temperatures can impair the grain-filling process in rice ( L.), potentially leading to the formation of chalky endosperm, but the molecular regulation mechanism remains largely elusive. Here, we reported that high-temperature (HT) stress (day/night, 35 °C/30 °C) reduces both the grain-filling rate and grain weight of Ningjing 1 variety compared to normal temperatures (NT, day/night, 28 °C/23 °C).
