Impact of near-infrared radiation in dermatology

Figure 4 A schematic of my near-infrared research and cell cycle. A: A schematic of my near-infrared (NIR) research; B: A schematic of the cell cycle and effects of NIR. NIR cannot penetrate the nuclear envelope due to the protection of nuclear lamins in interphase and telophase. NIR may damage the chromosomes of mitotic cells in prophase, metaphase and anaphase due to the absence of nuclear lamin protection, which results in apoptotic cell death.
