Background
Diabetes mellitus‐induced erectile dysfunction is difficult to treat. The oxidative stress created by diabetes mellitus is a major cause of injuries to the corpus cavernosum, thereby resulting in erectile dysfunction. Near‐infrared laser has already been shown to be effective in treating multiple brain disorders because of its antioxidative stress effect.
Objectives
To investigate whether...
Background
Due to the precise vaporization of the novel 450 nm blue diode laser in soft tissues (i.e., bladder and colon) in our previous studies, porcine stomach tissues were applied here to certify its efficacy in endoscopic mucosal resection (ESR)/endoscopic submucosal dissection (ESD) for hypothetical lesions ex vivo and in vivo.
Materials and Methods
In an ex vivo study of ESR, 20 pieces of...
To solve the problem of low efficiency and poor effect of the current tone mapping methods for the high dynamic range images, the authors propose a hierarchical tone mapping algorithm based on colour appearance model. The discrete Gaussian kernel is used to speed up the bilateral filter. The operation of tone compression in RGB colour space is adopted to correct the colour casts. The extreme values...
