¹Guizhou Medical University, ²Guizhou Health Vocational College

Four methods were used to detect intracellular Wolbachia, which complemented each other and improved the detection accuracy of Wolbachia infection of Aedes albopictus-derived Aa23 and Aa23-T cured of native Wolbachia infection using antibiotics.

Tropomodulin 3 (TMOD3) has been increasingly studied in tumors in recent years. This study is the first to report that TMOD3 is highly expressed in ovarian cancer and is closely associated with platinum resistance and immune infiltration. These results could help improve the therapeutic outcomes for ovarian cancer.

¹College of Computer Science and Technology, and Key Laboratory of Symbolic Computation and Knowledge Engineering of Ministry of Education, Jilin University, ²School of Biology and Engineering, Guizhou Medical University

Here, we introduce a protocol for converting transcriptomic data into a mqTrans view, enabling the identification of dark biomarkers. While not differentially expressed in conventional transcriptomic analyses, these biomarkers exhibit differential expression in the mqTrans view. The approach serves as a complementary technique to traditional methods, unveiling previously overlooked biomarkers.

Establishing a Severe Corneal Inflammation Model in Rats Based on Corneal Epithelium Curettage Combined with Corneal Sutures

Xiaoyu Tian^*1,2,3, Meng Zhang^*1,2, Yiming Wu⁴, Liying Zhang^1,2, Lingli Zhang^1,2, Xueer Zheng^1,2, Shangkun Ou^1,2, Hao Gu^1,2

¹Department of Ophthalmology, the Affiliated Hospital of Guizhou Medical University, ²School of Clinical Medicine, Guizhou Medical University, ³The Second People's Hospital of Guiyang City, ⁴Department of Biomedical Sciences, School of Infection, Inflammation and Immunology, College of Medicine and Health, University of Birmingham

We developed a rat model of severe corneal inflammation through corneal epithelium curettage combined with corneal sutures. The study evaluated corneal inflammation patterns, epithelial proliferation, and changes in limbal stem cells under inflammatory conditions.

Establishment of A Mouse Model of Aqueous Deficiency Dry Eye

Meng Zhang^*1,2, Xiaoyu Tian^*1,2, Yiming Wu³, Liying Zhang^1,2, Lingli Zhang^1,2, Xueer Zheng^1,2, Shangkun Ou^1,2, Hao Gu^1,2

¹Department of Ophthalmology, the Affiliated Hospital of Guizhou Medical University, ²School of Clinical Medicine, Guizhou Medical University, ³Department of Biomedical Sciences, School of Infection, Inflammation and Immunology, College of Medicine and Health, University of Birmingham

Here, we present a method to establish a mouse model of aqueous-deficient dry eye by excising the extraorbital and infraorbital lacrimal glands and evaluate the changes in the ocular surface in aqueous deficiency dry eye.
