RESUMEN

AIM: To conduct a bibliometric analysis of research on artificial intelligence (AI) in the field of glaucoma to gain a comprehensive understanding of the current state of research and identify potential new directions for future studies. METHODS: Relevant articles on the application of AI in the field of glaucoma from the Web of Science Core Collection were retrieved, covering the period from January 1, 2013, to December 31, 2022. In order to assess the contributions and co-occurrence relationships among different countries/regions, institutions, authors, and journals, CiteSpace and VOSviewer software were employed and the research hotspots and future trends within the field were identified. RESULTS: A total of 750 English articles published between 2013 and 2022 were collected, and the number of publications exhibited an overall increasing trend. The majority of the articles were from China, followed by the United States and India. National University of Singapore, Chinese Academy of Sciences, and Sun Yat-sen University made significant contributions to the published works. Weinreb RN and Fu HZ ranked first among authors and cited authors. American Journal of Ophthalmology is the most impactful academic journal in the field of AI application in glaucoma. The disciplinary scope of this field includes ophthalmology, computer science, mathematics, molecular biology, genetics, and other related disciplines. The clustering and identification of keyword nodes in the co-occurrence network reveal the evolving landscape of AI application in the field of glaucoma. Initially, the hot topics in this field were primarily "segmentation", "classification" and "diagnosis". However, in recent years, the focus has shifted to "deep learning", "convolutional neural network" and "artificial intelligence". CONCLUSION: With the rapid development of AI technology, scholars have shown increasing interest in its application in the field of glaucoma. Moreover, the application of AI in assisting treatment and predicting prognosis in glaucoma may become a future research hotspot. However, the reliability and interpretability of AI data remain pressing issues that require resolution.

RESUMEN

The first type II intramolecular [3 + 2] annulation of allenylsilane-ene has been achieved, enabling diastereoselective and efficient construction of synthetically challenging bridged five-membered ring systems such as bicyclo[3.2.1]. This mild and direct process shows a broad substrate scope and is highly stereospecific. Particularly, this work represents the first stereoselective method for the direct synthesis of bicyclo[3.2.1] ring systems from acyclic precursors. Additionally, the first asymmetric total syntheses of (+)- and (-)-strepsesquitriol, and the efficient formation of the synthetically challenging tetracyclic core of pierisjaponol D are achieved by this type II [3 + 2] annulation reaction.

RESUMEN

Rapid progression is the major cause of the poor prognosis of hepatocellular carcinoma (HCC); however, the underlying mechanism remained unclear. Here, we found Calpain-2 (CAPN2), a well-established protease that accelerates tumor progression in several malignancies, is overexpressed in HCC and acts as an independent predictor for poor outcomes. Furthermore, CAPN2 promoted the proliferation and invasion of HCC, and showed a positive correlation with the levels of invasion-related markers. Mechanistically, a novel CAPN2-SRC positive regulatory loop was identified upstream of ß-catenin to prevent its ubiquitination and degradation, and subsequently promoted HCC progression: CAPN2 could proteolyze PTP1B to form a truncation of approximately 42 kDa with increased phosphatase activity, resulting in reduced SRC Y530 phosphorylation and increased SRC kinase activity; meanwhile, CAPN2 itself was a bone fide substrate of SRC that was primarily phosphorylated at Y625 by SRC and exhibited increased proteolysis activity upon phosphorylation. Interestingly, the CAPN2-SRC loop could not only restrain most of cytoplasmic ß-catenin degradation by inhibiting GSK3ß pathway, but also prevented TRIM33-induced nuclear ß-catenin degradation even in ß-catenin-mutant cells. Present study identified a CAPN2-SRC positive loop responsible for intracellular ß-catenin accumulation and signaling activation, and targeting CAPN2 protease activity might be a promising approach for preventing HCC progression.

RESUMEN

OBJECTIVE: To evaluate the differences in the efficacy of stationary treatment and individualized treatment for patients with nonproliferative diabetic retinopathy (NPDR). METHODS: This study was a randomized, controlled, multicenter clinical trial. Participants with NPDR were randomized into the stationary treatment group or the individualized treatment group. The stationary treatment group was given the basic treatment and Qiming granules, and the individualized treatment group was given the basic treatment, Qiming granules, and individualized Chinese herbal medicines over a 12-week period. The individualized therapeutic formula was also changed over time to adjust to the changes in the clinical presentation of the patient. We conducted observations of fundus retinal exudation and hemorrhage, visual acuity, Traditional Chinese Medicine symptom scores and other indicators. RESULTS: A total of 140 participants with NPDR were randomized into the stationary treatment group or the individualized treatment group, and 132 participants completed this study. Following the 12-week treatment, significant improvements in both primary and secondary outcomes were observed in the stationary and individualized treatment groups. No remarkable difference in the primary outcomes between the two groups was observed. However, there was a significant difference in the Traditional Chinese Medicine symptom scores (18 ± 7 vs 15 ± 6; P < 0.05). There were no severe adverse effects. CONCLUSION: Compared with stationary treatment, individualized treatment is more effective at relieving the Traditional Chinese Medicine symptoms and improving vision and fundus lesions at 12 weeks post treatment.

RESUMEN

ortho-Selective carbene C-H insertion of unprotected phenols is achieved with dimethyl diazomalonate under the catalysis of [Rh(COD)Cl]2. After the C-H insertion, subsequent cyclization and electrophilic addition of another carbene molecule affords tris-carboxylate-substituted 2-benzofuranones as the final reaction products. The enantioselective variant has been developed with the use of chiral diene ligands. Mechanistic experiments indicate that a transient oxonium ylide directing group might be responsible for the regiocontrol at the C-H activation step.
