Abstract: A dissecting punch and tool configured for the dissection of follicular units from the donor area of a patient, such as for subsequent implantation of a follicular unit graft (FUG) in a recipient area for hair restoration, and method for using the tool. The method includes aligning the dissecting punch over a follicular unit so that hair follicles are disposed within the lumen. The dissecting punch is then moved through the dermis layer and into the fatty tissue layer of the skin to dissect the follicular unit from the tissue surrounding the follicular unit. The dissecting punch includes a non-circular shaft segment to reduce the transection rate of the follicular units during dissection.

Abstract: An extensible key management system includes a developer services portal for accessing an application. The system may identify initiation via the developer services portal of an association of the application with an external API of a third party provider service and automatically obtain a sub-key for the external API from the third party provider service on behalf of a developer of the application. The sub-key may be obtained in accordance with authorization provided by a master key previously provided from the third party provider service. The system may map an association between the sub-key, the application and the external API and store the association. Upon receipt of a service call message resulting from a request from a user device executing the application, the system may identify and replace a developer API key included in the service call message with the sub-key based on the stored association.

Abstract: An extensible single point orchestration system receives service requests from applications. In dependence upon the service request a single third party provider service or multiple third party provider services is identified. When the single third party provider service is identified, the system dynamically adapts a core capability service, using a stored configuration entity, so as to set an appropriate message format and transmit a service call message to an external API of the identified single third party provider service. When multiple third party provider services are identified, the system dynamically adapts the core capability service, using another stored configuration entity, so as to set a respective appropriate message format for parallel data transmission of service call messages to each of the respective identified third party provider services and transmits the service call messages to respective external APIs of each of the third party provider services.

Abstract: Embodiments of the invention relate to enhanced efficacy of agents (such as drugs) for treatment of skin tissue with photoactive particles, such as plasmonic nanoparticles, and light. Enhanced efficacy may result from, for example, enhanced delivery, activity, or release of the drug that is caused by the localized heat generated via the nanoparticles. Treatments are useful for cosmetic, diagnostic and therapeutic applications.
