Purpose: To establish optical coherence tomography (OCT) as an in vivo imaging modality for investigating the process of newt lens regeneration. Methods: Spectral-domain OCT was employed regeneration process. A total 37 newts were lentectomized and followed by over course 60 to 80 days. Histological images obtained at several time points compare with corresponding images. Volume measurements also acquired. Results: can identify key features observed histological based on scattering...

Aging and regeneration are heavily linked processes. While it is generally accepted that regenerative capacity declines with age, some vertebrates, such as newts, can bypass the deleterious effects of aging successfully regenerate a lens throughout their lifetime. Here, we used Spectral-Domain Optical Coherence Tomography (SD-OCT) to monitor process larvae, juvenile, adult newts. all three life stages were able through transdifferentiation dorsal iris pigment epithelial cells (iPECs), an...

To propose a time‐saving method for evaluating the fatigue strength of carburized steel, behavior and fracture mechanism 14Cr14Co13Mo5 steels are studied by rotary bending tests. It is found that crack initiation site changes from surface to internal after carburizing due residual compressive stress carbide cluster caused carburization. Besides, notable correlation between intensity cracked carbides at life observed in samples. This allows estimation long conditional based on samples tested...
