Disclosures

KH has worked in the area of wound healing for many years and has helped establish and sustain a section of wound healing in a university medical school. The school is entirely self-funded and receives funding from a wide range of commercial concerns in addition to the NHS and grant-giving bodies. The funding is provided to the University rather than to KH personally, and this funding is used to provide sustainability for a wide range of individuals employed within this section.
