Abstract

The field of medical education faces a significant challenge in teaching human anatomy, a fundamental aspect of medical science that is often perceived as complex and demanding. Understanding the shapes and anatomical structure locations is crucial for students to master the intricacies of anatomy. Visuospatial ability, which involves comprehending three-dimensional structures and their spatial relationships, plays a pivotal role in anatomy learning. The aim of this study was to examine keywords, territories/countries, the number of publications, institutions, authors, and associated journals related to visuospatial ability in anatomy learning through extensive bibliometric analysis. Data were gathered from the Scopus database, and VOSviewer was employed to conduct a bibliometric analysis. Approximately 552 eligible articles were examined in their entirety. The findings indicated that the most significant research growth occurred in 2012, with the United States of America emerging as the leading country in the field.  Furthermore, Anatomical Science Education was recognized as the most esteemed journal in this field, with Wilson, T.D. being credited as the most influential author. The bibliometric data also demonstrated various approaches to improve visuospatial capacity in anatomy learning, such as utilizing virtual reality or other computer-assisted learning modalities and their integration into medical education practice. In conclusion, these findings highlight the critical role of visuospatial ability in facilitating the acquisition of anatomical knowledge and offer direction for future research in this area.

Abstract

Evaluating long-term immunity after COVID-19 infection and vaccination is critical for managing potential outbreaks. The aim of this study was to develop a cost-effective in-house enzyme-linked immunosorbent assay (ELISA) based on Escherichia coli-expressed SARS-CoV-2 spike protein (E-S1) for antibody detection and to evaluate its performance. The system was validated by comparing the in-house ELISA results with those obtained using a commercial ELISA with HEK293-expressed spike protein (H-S1). Recombinant SARS-CoV-2 spike protein was produced in E. coli, purified, and validated for antigenicity via ELISA. Indirect ELISAs with both E-S1 and H-S1 antigens were performed on 386 serum samples from COVID-19 survivors, vaccinated individuals, and pre-pandemic controls collected at different time points. The E-S1 ELISA showed a statistically significant but weak correlation with H-S1 ELISA across all samples (r=0.205; p=0.0001). Stronger correlations were observed among vaccinated individuals with prior infection on day 90 (r=0.6017; p<0.001) and in naïve vaccine recipients on day 30 (r=0.5361; p=0.0003). Pre-pandemic sera from a rural population in Sumba Island exhibited high background reactivity in E-S1 ELISA, likely due to anti-E. coli antibodies, while urban pre-pandemic sera from Jakarta showed a stronger correlation with H-S1 ELISA. This suggests potential regional or immune background differences influencing assay performance. Although E-S1 retained antigenic properties, its diagnostic utility is limited by non-specific reactivity and reduced sensitivity compared to H-S1. In conclusion, E. coli expression systems may not be ideal for producing spike protein-based ELISA antigens specific to SARS-CoV-2. Alternative expression systems, such as human or baculovirus, could enhance diagnostic accuracy and specificity for COVID-19 antibody detection.
