Mechanisms of Human Cutaneous Microcirculation in Healthy Volunteers
October 30, 2017 updated by: University Hospital, Angers
Etude de la Reserve Vasomotrice Microcirculatoire cutanée
Microvascular dysfunctions are critical events in several diseases including diabetes.
This study will develop a methodology for microvascular investigation in human skin.
The purpose of the study is to investigate the physiological response of the cutaneous microcirculation to physical, thermal, mechanical or chemical stimulations.
