Article Synopsis
  • Accurate detection of driver gene mutations is key for treating lung cancer, but traditional methods require high-quality tissue samples and can be too slow or unavailable for many patients, especially in low-resource areas.
  • The study developed an AI model called DeepGEM, which uses routine histological slides to predict gene mutations without needing prior annotation or high-quality samples.
  • The model was trained and tested on a large dataset of lung cancer patients across multiple hospitals in China, showing promising results in predicting gene mutations, which was further validated on external and public datasets.

Background: The compromised well-being of educators engenders a range of educational, social, and economic issues that cannot be adequately addressed through the mere awareness of risk factors. The present research explores the mediating roles of self-compassion and emotion regulation strategies (cognitive reappraisal and expressive suppression) on the relationship between academic teachers' psychological resilience and mental health.

Methods: A total of 405 academic teachers from four colleges in Tabuk City, Saudi Arabia, participated in the study between September and November 2023.

Article Synopsis
  • Pseudomyxoma peritonei (PMP) is a rare tumor that mimics malignant behavior, traditionally treated with surgical resection and chemotherapy, though results are often poor.
  • Newer treatments combining cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) are being studied for their safety and effectiveness in treating PMP.
  • An observational study of 186 PMP patients treated with CRS + HIPEC revealed a median age of 56, a 30-day postoperative fatality rate of 2.7%, and a significant incidence of complications, particularly anemia, although most patients did not achieve satisfactory CRS outcomes.

MicroRNA-146a-5p (miR-146a-5p) actively participates in the process of cerebral ischemia-reperfusion (CI/R) injury. Dysregulation of the tumor necrosis factor receptor-associated factor 6 (TRAF6)/nuclear factor kappa-B (NF-κB) p65 axis is closely associated with inflammatory response. This study aimed to investigate the potential involvement of miR-146a-5p and TRAF6/NF-κB p65 in mediating CI/R progression in vitro.

Extrachromosomal DNA (ecDNA) refers to a class of circular, non-chromosomal DNA that has recently gained widespread attention due to its potential role in aging and neurodegenerative diseases. The generation of ecDNA is closely associated with processes such as double-strand breaks, micronuclei formation, and the breakage-fusion-bridge (BFB) cycle, all of which are integral to regulation of gene expression, genetic stability, and clonal evolution. In neurodegenerative diseases such as Alzheimer's disease, Parkinson's disease, and Huntington's disease, the aberrant formation of ecDNA is closely linked to defects in DNA repair, alterations in synaptic plasticity, and neuronal dysfunction.

Fra-1 affects chemotherapy sensitivity by inhibiting ferroptosis in gastric cancer cells.

Cancer Drug Resist

November 2024

Cancer Research Institute, Basic School of Medicine, Central South University, Changsha 410011, Hunan, China.

Gastric cancer (GC) is one of the common malignant tumors, and most patients with advanced GC often develop chemotherapy resistance, resulting in poor chemotherapy efficacy. Therefore, it is crucial to clarify the specific mechanisms of their chemotherapy resistance. In this study, we analyzed the correlation between fos-related antigen-1 (Fra-1) and chemotherapy resistance in GC using bioinformatics, cell counting kit-8 (CCK8), and 5-ethynyl-2'-deoxyuridine (EDU) combined with flow cytometry; furthermore, we used energy metabolomics sequencing, combined with ChIP-qPCR technology, to elucidate the specific role of Fra-1 in chemotherapy resistance of GC cells and its related mechanisms.

Article Synopsis
  • * Research on heart transplants with mismatched MHC class II revealed that graft-derived IL-33 activates tissue repair pathways in Tregs and macrophages, with a notable impact from regulating amphiregulin (Areg) expression.
  • * Deleting Areg specifically in Tregs indicated that Areg promotes chronic rejection through increased fibroblast growth, suggesting that the interplay between IL-33 from fibroblasts and Tregs is crucial for advancing CR in transplanted organs.

A novel tape-free sample preparation method for human osteochondral cryosections for high throughput hyperspectral imaging.

Histochem Cell Biol

December 2024

School of Mechanical, Medical & Process Engineering, Queensland University of Technology, 60 Musk Ave/Cnr. Blamey St, Kelvin Grove, Brisbane, QLD, 4059, Australia.

Understanding the osteochondral junction, where non-mineralised cartilage and mineralised bone converge, is crucial for joint health. Current sample preparation techniques are insufficient for detailed spatial hyperspectral imaging analysis. Using the enhanced Kawamoto method, we used the super cryo embedding medium's temperature-dependent properties to transfer high-quality tissue samples onto slides for spatial imaging analysis.

Intestinal mucosal immunity and type 1 diabetes: Non-negligible communication between gut and pancreas.

Diabetes Obes Metab

December 2024

National Clinical Research Center for Metabolic Diseases, Key Laboratory of Diabetes Immunology (Central South University), Ministry of Education, and Department of Metabolism and Endocrinology, The Second Xiangya Hospital of Central South University, Changsha, China.

Type 1 diabetes (T1D) is a chronic autoimmune disease characterized by T cell-mediated pancreatic β cell loss, resulting in lifelong absolute insulin deficiency and hyperglycaemia. Environmental factors are recognized as a key contributor to the development of T1D, with the gut serving as a primary interface for environmental stimuli. Recent studies have revealed that the alterations in the intestinal microenvironment profoundly affect host immune responses, contributing to the aetiology and pathogenesis of T1D.
