With a video-rate third harmonic generation (THG) microscopy system, we imaged the micro-circulation beneath the human skin without labeling. Not only the speed of circulation but also the morpho-hydrodynamics of blood cells can be analyzed. Lacking of nuclei, red blood cells (RBCs) shows typical parachute-like and hollow-core morphology under THG microscopy. Quite different from RBCs, every no...

The heart drives two separate and distinct circulatory systems in the body: the pulmonary circulation and the systemic circulation. The pulmonary circulation is analogous to the entire systemic circulation. Similar to the systemic circulation, the pulmonary circulation receives all of the cardiac output. Therefore, the pulmonary circulation is not a regional circulation like the renal, hepatic,...

A static model of cerebral blood circulation is constructed for developing an automatic control system of physiological brain state, which will be used in brain resuscitation. In this paper, the constructed model was partially verified in the simulation using the actual data of a 70 years old patient with stenosis at left internal carotid artery. In the simulation, each arterial blood flow in c...
