We have compared the electrical performance of a proposed normally-off GaN-based MIS-HEMTs employing ultrathin AlGaN barrier layer in the channel with those of conventional recessed-gate structure MIS-HEMTs. The proposed device exhibited much less density of interface states extracted from the measured capacitance-voltage characteristics, suggesting improved Al2O3/AlGaN interface. For corresponding three-terminal transistors, while the conventional reference device exhibited poor control of gate-to-source voltage on drain current with about 3 V hysteresis in the transfer curves, the proposed device showed well-behaved subthreshold characteristics with only 0.8 V hysteresis. Furthermore, the proposed device showed a much higher VTH of +5 V compared to +1 V of the conventional reference device.

[Purpose] Eccentric exercise induces a decrease in vascular endothelial function. Curcumin, a major component of turmeric, has potent antioxidant and anti-inflammatory properties that are associated with vascular protective effects. The present study examined the effect of acute supplementation of curcumin on eccentric exercise-induced endothelial dysfunction in healthy young men. [Methods] Fourteen healthy sedentary young men (range, 21–29 years) were assigned to either the curcumin (n = 6) or placebo (n = 8) group. All subjects consumed either curcumin or placebo before exercise, and eccentric exercise of the elbow flexors was performed with their nondominant arm. Before and 60 min after exercise, brachial artery flow-mediated dilation (FMD), as an indicator of endothelial function, was measured in the non-exercised arm. [Results] Brachial artery FMD significantly decreased following eccentric exercise (p < 0.05) in the placebo group, but acute supplementation with curcumin before exercise nullified this change. The change in FMD before and after eccentric exercise between the placebo and curcumin groups was significantly different (p < 0.05). [Conclusion] The present study found that acute curcumin supplementation could attenuate the decrease in endothelial function, as measured by FMD, following eccentric exercise in healthy young men.
