Article Synopsis
  • - A new retron named retron-Vmi1 was discovered in Vibrio mimicus, which plays a key role in producing a small satellite DNA-RNA complex (msDNA) through the bacterial reverse transcriptase (RT) gene.
  • - The genetic structure of retron-Vmi1 is similar to another retron found in Salmonella, indicating related evolutionary pathways between these organisms.
  • - Evidence shows that retrons can be transferred between species, as retron-Vmi1 was found inserted in the dusA gene in a manner akin to a similar retron in V. parahaemolyticus, suggesting a complex evolutionary relationship among these bacteria.

Rationale: Hair is known to preserve diet history and other physiological information during its growth period and is often used in chemical analyses. However, the growth patterns and turnover of hair vary according to the animal species or habitat, so understanding these patterns in the target animal is necessary for interpreting the results of hair analyses. In this study, we aimed to elucidate the growth pattern and dietary information of winter coat hair in captive sika deer (Cervus nippon).

There are numerous approaches for transcatheter aortic valve replacement (TAVR); however, access-related complications remain a point of concern. We analyzed consecutive patients who underwent TAVR for severe aortic stenosis via the brachiocephalic artery (BCA) without sternotomy (TBc group, n = 10) and via the trans-ascending aortic (TAo group, n = 8). The median BCA diameter and distance between the access point and suprasternal notch or superior margin of the clavicle were 11.
