BACKGROUND Dipeptidyl peptidase-4 (DPP-4) inhibitors modulate incretin hormones and exert anti-diabetic effects in type 2 diabetes mellitus. Treatment with angiotensin II type 1 receptor blockers (ARB) is a proven successful intervention for hypertension with type 2 diabetes. The present study investigated the combined effects of the DPP-4 inhibitor(More)
BACKGROUND The induction of heat shock protein (HSP) 72 by mild electrical stimulation with heat shock (MES + HS), which improves visceral adiposity and insulin resistance in mice, may be beneficial in treating metabolic syndrome (MS) or type 2 diabetes mellitus (T2DM). METHODS Using open-label crossover trials, 40 subjects with MS or T2DM were randomly(More)
The male part of the spadix of Dracunculus vulgaris exhibits a degree of temperature regulation by inversely controlled heat production over a 20–35 °C range of tissue temperature. To clarify the effects of temperature on cellular metabolism, comparative analysis was performed using 51 metabolites from two distinct tissues (florets and pith) of thermogenic(More)
—In this paper, we consider to formulate an image data hiding scheme based on error diffusion. By using the scheme, visual patterns are embedded in a halftone image without affecting its perceptual quality depending on a halftone key image. The scheme has the feature of visual cryptography with respect to extracting of the embedded patterns, i.e., when we(More)
Recently, various ways to reduce the size of multimedia data have been developed. However, there is a problem of the tradeoff of data size, and quality. In compressed audio encoding, high frequency components are lost from the original signal. It is impossible to retrieve the frequency components that have been cut using the conventional interpolation(More)
We study formulating the ubiquitous cloud (UC) model proposed by Murakami at KDDI [4]. Based on the analysis for Ad Hoc wireless network by Gupta and Kumar [3], we rearrange their setting to an appropriate one for the UC, and then give an evaluation of network capacity called transport capacity. The evaluation takes the form similar to [3], when(More)
