For Youthful Skin,
Skin microcirculation hypofunction/dysfunction might play a significant role in the development of some skin diseases, such as acne and seborrhea. Skin microcirculation plays a significant role in skin homeostasis. Dermal venules are important for waste removal from the skin, whilst dermal arterioles are important for the transportation of gases (oxygen) and nutrients toward the skin.
Skin blood flow function that determines the ability of the skin in response to ischemic stress has been proposed to be a good indicator for identifying people at risk of pressure ulcers. Wavelet spectral and nonlinear complexity analyses have been performed to investigate the influences of the metabolic, neurogenic and myogenic activities on microvascular regulation in people with various pathological conditions. These findings have contributed to the understanding of the role of ischemia and viability on the development of pressure ulcers. Read More >>
Microcirculation represents the smallest functional unit of the cardiovascular system, where the interaction between blood and tissue creates the environment necessary for cell function. Analysis of physiology and pathophysiology of this system gives a unique perspective to the disease process, and provides the link between clinical and molecular medicine. Read More >>
Age-related changes in skin contribute to impaired wound healing after surgical procedures. Changes in skin with age include decline in thickness and composition, a decrease in the number of most cell types, and diminished microcirculation. The microcirculation provides tissue perfusion, fluid homeostasis, and delivery of oxygen and other nutrients. It also controls temperature and the inflammatory response. Read More >>
Human longevity has been previously linked by researchers to genetic factors, calorie restriction, and certain life-style factors such as physical activity or the Mediterranean diet. Now, Italian researchers from La Sapienza University in Rome have identified an additional factor, which significantly contributes to a longer life. In a pilot study on some of the oldest people of the world, they discovered that the perfusion of organs and muscles of the centenarians was as efficient as that in people who were 30 years younger.
