Background Brucellosis is a severe zoonotic disease that is often overlooked, particularly in impoverished countries. Timely identification of focal complications in brucellosis is crucial for improving treatment outcomes. However, there is currently a lack of established indicators or biomarkers for diagnosing these complications. Therefore, this study aimed to investigate potential warning signs of focal complications in human brucellosis, with the goal of providing practical parameters for clinicians to aid in the diagnosis and management of *** A multi-center cross-sectional study was conducted in China from December 2019 to August 2021. The study aimed to investigate the clinical characteristics and complications of patients with brucellosis using a questionnaire survey and medical record system. The presence of warning signs for complications was assessed using univariate and multivariate logistic regression models. Receiver operating characteristic (ROC) curves and the area under the curve (AUC) were used for variable screening and model *** A total of 880 participants diagnosed with human brucellosis were enrolled. The median age of the patients was 50 years [interquartile range (IQR): 41.5-58.0], and 54.8% had complications. The most common organ system affected by complications was the osteoarticular system (43.1%), with peripheral arthritis (30.0%), spondylitis (16.6%), paravertebral abscess (5.0%), and sacroiliitis (2.7%) being the most prevalent. Complications in other organ systems included the genitourinary system (4.7%), respiratory system (4.7%), and hematologic system (4.6%). Several factors were found to be associated with focal brucellosis. These factors included a long delay in diagnosis [odds ratio (OR) = 3.963, 95% confidence interval(CI): 1.906-8.238 for > 90 days], the presence of underlying disease (OR = 1.675, 95%CI: 1.176-2.384), arthralgia (OR = 3.197, 95%CI: 1.986-5.148), eye bulging pain (OR = 3.482, 95%CI:

RNPS1 stabilizes NAT10 protein to facilitate translation in cancer via tRNA ac^(4)C modification

引用

International Journal of Oral Science 2024年第1期16卷 73-84页

作者： Xiaochen Wang Rongsong Ling Yurong Peng Weiqiong Qiu Demeng Chen center For Translational Medicine the First Affiliated HospitalSun Yat-sen UniversityGuangzhouChina Institute for Advanced study Shenzhen UniversityShenzhenChina

Existing studies have underscored the pivotal role of N-acetyltransferase 10(NAT10) in various cancers. However, the outcomes of protein-protein interactions between NAT10 and its protein partners in head and neck squamous cell carcinoma(HNSCC) remain unexplored. In this study, we identified a significant upregulation of RNA-binding protein with serine-rich domain 1(RNPS1) in HNSCC, where RNPS1 inhibits the ubiquitination degradation of NAT10 by E3 ubiquitin ligase, zinc finger SWIM domain-containing protein 6(ZSWIM6), through direct protein interaction, thereby promoting high NAT10 expression in HNSCC. This upregulated NAT10 stability mediates the enhancement of specific tRNA ac^(4)C modifications, subsequently boosting the translation process of genes involved in pathways such as IL-6 signaling, IL-8 signaling, and PTEN signaling that play roles in regulating HNSCC malignant progression, ultimately influencing the survival and prognosis of HNSCC patients. Additionally, we pioneered the development of TRMC-seq, leading to the discovery of novel t RNA-ac^(4)C modification sites, thereby providing a potent sequencing tool for tRNAac^(4)C research. Our findings expand the repertoire of tRNA ac^(4)C modifications and identify a role of tRNA ac^(4)C in the regulation of mRNA translation in HNSCC.

Science China Chemistry 2024年

作者： Qinghui Zeng Yongteng Dong Yuanmao Chen Xinyang Yue Zheng Liang Frontiers Science center for Transformative Molecules Zhang Jiang Institute for Advanced Study Shanghai Jiao Tong University

The escalating demand for fast-charging lithium-ion batteries(LIBs) has mirrored the rapid proliferation and widespread adoption of electric vehicles and portable electronic devices. Nonetheless, the sluggish diffusion kinetics of lithium ions and electrode degradation in conventional graphite-based anodes pose formidable hurdles in achieving optimal fast-charging capabilities for LIBs. To overcome these challenges, the innovative concept of fast-charging composite anodes, a paradigm shift from traditional single-component designs, has emerged as a promising avenue to enhance the overall performance of LIBs under rapid charging conditions. This paper provides a comprehensive review of the recent advancements in fast-charging composite anodes for LIBs, with a pivotal emphasis on the design principles and material selection strategies employed in various composite anode formulations. Furthermore, it outlines the future prospects and research trajectories in this burgeoning field, offering insights into potential breakthroughs and directions for further exploration.
