  • Publication number: 20230416677
    Abstract: The present invention relates to a culture medium composition obtained by further adding at least one selected from the group consisting of rotenone and albumin to a serum-free medium prepared through a CAMPs technology. It has been ascertained that the proliferation of dermal papilla cells and maintenance of characteristics thereof during culturing can be improved by regulating the concentration of rotenone and albumin, and since the culture medium composition is a serum-free chemical medium comprising no serum, there is no risk of side effects, which can be caused by using a conventional serum medium, during use on the human body. The culture medium composition of the present invention obtained by further adding at least one selected from the group consisting of rotenone and albumin to a serum-free medium, or dermal papilla cells cultured through the composition can be effectively used in the development of therapeutic agents for hair loss prevention and hair growth promotion.

  • Publication number: 20210257317
    Abstract: Distributions of on-chip inductors for monolithic voltage regulation are described. On-chip voltage regulation may be provided by integrated voltage regulators (IVRs), such as a buck converter with integrated inductors. On-chip inductors may be placed to ensure optimal voltage regulation for high power density applications. With this technology, integrated circuits may have many independent voltage domains for fine-grained dynamic voltage and frequency scaling that allows for higher overall power efficiency for the system.
