encouraging effects of a short term adapted nordic diet intervention on skin microvascular function and skin Oxygen tension in younger and older adults
Nutrition, 2017Co-Authors: David Rogerson, Scott Mcneill, Heidi Kononen, Markos KlonizakisAbstract:Abstract Objectives The microvascular benefits of regional diets appear in the literature; however, little is known about Nordic-type diets. We investigated the effects of a short-term, adapted, Nordic diet on microvascular function in younger and older individuals at rest and during activity. Methods Thirteen young (mean age: 28 y; standard deviation: 5 y) and 15 older (mean age: 68 y; standard deviation: 6 y) participants consumed a modified Nordic diet for 4 wk. Laser Doppler flowmetry and Transcutaneous Oxygen Monitoring were used to assess cutaneous microvascular function and Oxygen tension pre- and postintervention; blood pressure, body mass, body fat percentage, ratings of perceived exertion, and peak heart rate during activity were examined concurrently. Results Axon-mediated vasodilation improved in older participants (1.17 [0.30] to 1.30 [0.30]; P Conclusions We observed statistically significant improvements in microvascular function, peak heart rate, and body composition. An adapted Nordic diet might improve microvascular health.

assessing the effects of a short term green tea intervention in skin microvascular function and Oxygen tension in older and younger adults
Microvascular Research, 2016Co-Authors: Rebecca Wasilewski, Emmanuel O Ubara, Markos KlonizakisAbstract:Green tea consumption has been associated with a reduction in cardiovascular disease risk factors. However, there is little evidence examining its potential differing effect between younger and older populations, whilst little is known on its effect on the circulatory system when Oxygen demand is higher. Therefore the aim of this study was to evaluate the short-term effects of green tea consumption on microvascular functioning in both an older and younger population. Fifteen young [24 (4.0)] and fifteen older [61 (4.0)] participants, consumed two cups of green tea daily for 14days. We used Laser Doppler Flowmetry (LDF) to assess cutaneous microvascular function and Transcutaneous Oxygen Monitoring (TcPO2) to assess skin Oxygen tension. Systolic and diastolic blood pressure were also assessed on both visits. We observed significant improvements in axon-mediated microvascular vasodilation for the younger group [1.6 (0.59) vs 2.05 (0.72), p<0.05] and the older group [1.25 (0.58) vs 1.65 (0.5) p<0.05]. Improvements in skin Oxygen tension were also noted for both groups in both noted TcPO2 measures (i.e. 1.25 (0.58) vs 1.65 (0.5) (p<0.05), for ΔTcPO2max for the older group, between visits) respectively. Improvements were also observed for systolic blood pressure in both the younger [120 (10) vs 112 (10), p<0.05] and older group [129 (12) v 124 (11), p<0.001]. In conclusion, we observed statistically-significant improvements in microvascular function and skin Oxygen tension. Our results suggest that green tea may prove beneficial as a dietary element in lifestyle interventions aiming to lower cardiovascular disease risk, in both older and younger populations.

wearable luminescent Oxygen sensor for Transcutaneous Oxygen Monitoring
ACS Applied Materials & Interfaces, 2018Co-Authors: Jin Woo ParkAbstract:We present a new concept for a wearable Oxygen (O2) sensor for Transcutaneous O2 pressure (tcpO2) Monitoring by combining the technologies of luminescent gas sensing and wearable devices. O2 Monitoring has been exhaustively studied given its central role in diagnosing various diseases. The ability to quantify the physiological distribution and real-time dynamics of O2 from the subcellular to the macroscopic level is required to fully understand mechanisms associated with both normal physiological and pathological conditions. Despite its profound biological and clinical importance, few effective methods exist for noninvasively quantifying O2 in a physiological setting. The wearable sensor developed here consists of three components: a luminescent sensing film attached onto skin by a carbon tape, an organic light-emitting diode (OLED) as a light source, and an organic photodiode (OPD) as a light detector. All the components are solution-processable and integrated on a plane in a bandage-like configuration. ...

wearable luminescent Oxygen sensor for Transcutaneous Oxygen Monitoring

All the components are solution-processable and integrated on a plane in a bandage-like configuration. To verify the performance, tcpO2 variations by pressure-induced occlusion were measured in the lower arm and a thumb by the wearable sensor, and the results were comparable to those measured by a commercial instrument. In addition to its flexibility, other features of this sensor render it a potential low-cost solution for the simultaneous Monitoring of tcpO2 in any part of a body.
