Abstract: The present disclosure pertains to provision of: a tear layer stabilizer; a prophylactic agent, ameliorating agent, and therapeutic agent for corneal epithelial disorders; a prophylactic agent, ameliorating agent, and therapeutic agent for meibomian gland dysfunction; and a prophylactic agent, ameliorating agent, and therapeutic agent for dry eye. More specifically, provided are a tear layer stabilizer, a prophylactic agent, ameliorating agent, and therapeutic agent for corneal epithelial disorders, and a prophylactic agent, ameliorating agent, and therapeutic agent for meibomian gland dysfunction, and a prophylactic agent, ameliorating agent, and therapeutic agent for dry eye, each of which composition contains apocynin as an active ingredient.

Abstract: The present invention pertains to: the provision of a method for promoting skin wound healing and a composition to be used for promoting skin wound healing; the provision of a method useful for preventing or ameliorating ulcers and bedsores or a composition therefor; the provision of a method for preventing skin aging and a composition to be used for preventing skin aging; the provision of a composition useful for preventing or ameliorating skin damage caused by an anticancer agent; and, furthermore, the provision of a method for enhancing the regeneration ability of epidermal stem cells and a composition for enhancing the regeneration ability of epidermal stem cells.

Abstract: Even for the case where cells such as human epidermal keratinocytes form a dense colony, or the case where cell contours are indefinite, each of the cells is automatically tracked with high precision, and behavior of each cell is analyzed with good precision. There is provided a method for analyzing behavior of a cell, which comprises a detection step of detecting positions of a plurality of cells for every frame of time-lapse images, while determining whether a candidate region extracted from the frame is a cell region by using a dictionary containing image data of cell nuclei; and a tracking step of tracking each cell by using a state space model using position of a most adjacent cell within a predetermined distance from a predicted position as observation data. When any cell is not found within a certain distance from the predicted position, data are considered missing.

Abstract: The present invention provides novel compositions for suppressing or improving hair loss, and compositions for suppressing or improving graying. More specifically, it provides agents that stabilize type XVII collagen expression, preferably agents that suppress the degradation of type XVII collagen by ELANE inhibitors and such, and compositions comprising a DNA repair-promoting agent or a DNA damage-suppressing agent as an active ingredient. Advantageous suppressive effects of hair loss and graying can be obtained when a composition comprising as an active ingredient a suppressive agent of type XVII collagen degradation such as an ELANE inhibitor is administered to a mammal. For the ELANE inhibitors, suppressive agents of type XVII collagen degradation and DNA repair-promoting agents, low-molecular compounds, polypeptides, proteins, antibodies, or nucleic acid medicine such as antisense oligos or siRNAs may be used.
