Abstract: The present disclosure relates to a composition for gene editing and a use thereof. According to the present disclosure, an adenine base editor LbABE8e system in which a Cas12a protein variant including one or more mutations and adenine deaminase are fused has altered PAM specificity to achieve a significant genomic single base editing effect on target DNA, and thus expands the range of applicable CRISPR system selection. Accordingly, due to gene editing, it is expected that the adenine base editor LbABE8e system may be widely used in various fields, such as gene therapy, creation of commercial profits with industrial strains with improved productivity, improvement of the quality of public health care through improvement of intestinal microorganisms, and improvement of crops and livestock breeds free from GMO issues.

Abstract: The present invention relates to a composition comprising vascular endothelial progenitor cells and mesenchymal stem cells as active ingredients for prevention or treatment of occlusive vascular diseases or complications thereof. Since it was found that vascular endothelial progenitor cells and mesenchymal stem cells remarkably improved vascularization ability upon application thereof in combination, the present invention has the effect of providing a new cell therapy product for prevention or treatment of occlusive vascular diseases or ulcers resulting therefrom, and a preparation method therefore.

Abstract: A circuit for preventing power imbalance of a resonance-type power converter is proposed. The circuit may include a rectifier converting input alternating current (AC) into direct current (DC) and frequency-controlled first and second resonant converter modules configured to receive an output voltage of the rectifier divided into two stages. The circuit may further include a controller outputting a first frequency command for controlling a frequency of a pulse width modulation (PWM) signal supplied to a switching element of a first switching unit of the first resonant converter module. The circuit may further include a frequency compensator compensating for the first frequency command and then outputting a second frequency command for controlling a frequency of a PWM signal supplied to a switching element of a second switching unit of the second resonant converter module, so as to eliminate power imbalance between the first and second resonant converter modules.
