Red-Near Infrared Light Stimulates Release of an Endothelium Dependent Vasodilator and Rescues Vascular Dysfunction in a Diabetes Model
Peripheral artery disease (PAD) is a morbid condition whereby ischemic peripheral muscle causes pain and tissue breakdown. Interestingly, PAD risk factors, e.g. diabetes mellitus, cause endothelial dysfunction secondary to decreased nitric oxide (NO) levels, which...
Passive Heat Therapy Improves Cutaneous Microvascular Function Insedentary Humans via Improved NO-Dependent Dilation
Passive heat therapy (repeated hot tub or sauna use) reduces cardiovascular risk, but its effects on the mechanisms underlying improvements in microvascular function have yet to be studied. We investigated the effects of heat therapy on microvascular function and...
Local Passive Heat for the Treatment of Hypertension in Autonomic Failure
Supine hypertension affects a majority of patients with autonomic failure; it is associated with end-organdamage and can worsen daytime orthostatic hypotension by inducing pressure diuresis and volume loss during the night. Because sympathetic activation prevents...
Ultraviolet Radiation-Induced Production of NO – A Multicell and Multi-Donor Analysis
Increasing evidence regarding positive effects of exposure to sunlight has led to suggestions that current advice may be overly weighted in favor of avoidance. UV-A has been reported to lower blood pressure, possibly through nitric oxide (NO) production in skin. Here,...
The Impact of Wavelengths of LED Light-Therapy on Endothelial Cells
Low level light therapy receives increasing interest in the fields of tissue regeneration and wound healing. Several in vivo studies demonstrated the positive effects of LLLT on angiogenesis. This study aimed to investigate the underlying properties in vitro by...
Blue Light Exposure Decreases Systolic Blood Pressure, Arterial Stiffness, and Improves Endothelial Function in Humans
Aims: Previous studies have shown that ultraviolet light can lead to the release of nitric oxide from the skin and decrease blood pressure. In contrast to visible light the local application of ultraviolet light bears a cancer ogenic risk. Here, we investigated...
Blue Light can Reduce Blood Pressure, Study Suggests
Exposure to blue light decreases blood pressure, reducing the risk of developing cardiovascular disease, a new study from the University of Surrey and Heinrich Heine University Dusseldorf in collaboration with Philips reports. During this study, published in the...
Two Color Laser Absorption
An infrared laser-absorption technique for in situ temperature and nitric oxide species sensing in high-temperature gases is presented. A pair of quantum cascade lasers in the mid-infrared near 5 were utilized to probe rovibrational transitions in nitric oxide’s...
