The Role of Heat Shock Response in Insulin Resistance and Diabetes

The expansion of life-style related diseases, such as metabolic syndrome (MS) and type 2 diabetes mellitus (T2DM), appears to be unstoppable. It is also difficult to cease their complications in spite of many antidiabetic medications or intervention of public administration. We and our collaborators found that physical medicine using simultaneous stimulation of heat with mild electric current activates heat shock response, thereby reducing visceral adiposity, insulin resistance, chronic inflammation and improving glucose homeostasis in mice models of T2DM, as well as in humans with MS or T2DM. This combination therapy exerts novel action on insulin signaling, β-cell protection and body compositions, and may provide a new therapeutic alternative in diabetic treatment strategy.
Effect of Heat Treatment on the Acoustic Properties of a Wooden Xylophone Keyboard

<P>To estimate changes in the acoustic properties of a wooden xylophone keyboard caused by heat treatment, the resonant frequencies and logarithmic decrement of control and heat treated specimens of Yezo spruce (Picea jezoensis), Northern red oak (Quercus rubra) and Japanese red pine (Pinus densiflora S. et Z.) were evaluated by the free vibration method. A flexural vibiation test was carried out by the xylophone stick free fall impact test. The changes in resonant frequency of the first mode and those of other modes by heat treatment were evaluated. And the changes in logarithmic decrement by heat treatment were evaluated. As a result of heat treatment, the resonant frequencies of the 1st mode of all specimens were decreased, and within a species the wood specimens of higher resonant frequencies were more influenced. In the case of the specimen with a higher resonant amplitude at the 2nd mode resonance frequency, the resonant amplitude of the 1st mode resonance frequency was increased more by heat treatment, so that the sound became more stable.</P>

Some fire-retardant woods with no documented fire performance have occasionally been sold in the market. It is important to know whether the required amount of chemical fire retardant is present in all sections of a wood sample. In this study, nondestructive measurement of chemical retention in fire-retardant treated wood was experimentally investigated using air-coupled ultrasonic and micro focus X-ray computed tomography. Wood samples were impregnated with different chemical concentrations. First, the ultrasonic wave velocities of wood samples were measured before and after impregnation. The percent changes in velocity exhibited a positive correlation with the chemical retention. Second, the images of wood sample were captured using X-ray CT before and after impregnation. The changes in integrated brightness values calculated from the captured images also showed a positive correlation with the chemical retention at a 1% significance level. These findings suggest that it is possible to evaluate the distributions of chemical retention in fire-retardant wood.
