Purpose: To identify the impact of endovascular simulator training and shadowing in interventional radiology on medical students' self-assessed IR knowledge. Moreover, the sequence of the teaching methods and its influence on the self-assessed IR knowledge is investigated.
Materials And Methods: A total of 19 fourth-year medical students participated in this study. Eleven students completed shadowing live cases first and endovascular simulator training the following day. Eight students completed the teaching in reversed order. Questionnaires were completed before and after each teaching method. The students assessed their knowledge of instruments and materials, steps of the Seldinger technique, and aortography on a Likert scale (1 = "I do not agree at all," 5 = "I fully agree").
Results: After simulator training, the students stated a significant increase in perceived knowledge compared with baseline (p < 0.001). Shadowing led to a significant improvement regarding the items "knowledge of instruments and materials" (3.2 vs. 3.8, p = 0.008) and "steps of the Seldinger technique" (3.7 vs. 3.9, p = 0.046). Self-assessed knowledge after simulator training increased significantly more regarding Seldinger technique compared with shadowing (+ 1.2 vs. + 0.2, p < 0.001). Simulator training before shadowing was significantly more effective regarding the increase in "knowledge of the steps of aortography" compared with the reverse sequence (+ 2.0 vs. + 0.9, p = 0.041).
Conclusion: Endovascular simulator training and shadowing are both feasible tools to improve medical students' perceived knowledge of interventional radiology. When organizing teaching, simulator training before shadowing can have a positive impact on self-assessed knowledge.

Single-cell RNA sequencing (scRNA-seq) offers remarkable insights into cellular development and differentiation by capturing the gene expression profiles of individual cells. The role of dimensionality reduction and visualization in the interpretation of scRNA-seq data has gained widely acceptance. However, current methods face several challenges, including incomplete structure-preserving strategies and high distortion in embeddings, which fail to effectively model complex cell trajectories with multiple branches.

Antibody generation requires the use of one or more time-consuming methods, namely animal immunization, and in vitro display technologies. However, the recent availability of large amounts of antibody sequence and structural data in the public domain along with the advent of generative deep learning algorithms raises the possibility of computationally generating novel antibody sequences with desirable developability attributes. Here, we describe a deep learning model for computationally generating libraries of highly human antibody variable regions whose intrinsic physicochemical properties resemble those of the variable regions of the marketed antibody-based biotherapeutics (medicine-likeness).
