Consideration of Stretchable Dry Electrodes for Smart Shirts Aimed for Biological Signal Monitoring

Dry electrodes of a smart shirt for measuring biological signals were prepared by the additive printing method using a stretchable conductive paste with Ag fillers loading. Interfacial impedance between the electrode and skin depended on the contact pressure of electrode and the moisture of stratum corneum. When moisture of stratum corneum was more than 30%, ECG could be measured using the stretchable electrodes printed on a compression shirt. However, noise signal in the ECG signal increased when the moisture of stratum corneum was less than 30%. To solve this problem, we propose to use additional electrodes made of an electrically conductive kneaded rubber.

Fish Myosin Fragments Solubility and ANS-Fluorescence Intensity Affected by n-Butanol

Changes in the solubility and 8-anilino-1-napthalene sulfonate (ANS)-fluorescence intensity of oval filefish, tilapia, and black marlin myo-sins and their fragments by n-butanol were examined in connection with myosin gel-forming abilities. The thermal gel-forming abilities of myosins were greatly enhanced by the addition of 0.3–0.8M n-butanol. KC1 concentration-solubility curves revealed that after n-butanol addition a marked decrease in the solubility was observed for myosins and S-1s, whereas there was a slight decrease for rods. The fluorescence intensity of myosins-ANS in the presence of n-butanol increased markedly by heating at 30° and 35°C. A similar increase in the fluorescence intensity occurred in all S-ls-ANS, but not in rods.     

Protein-Protein Interaction of Fish Myosin Fragments

Protein-protein interaction of myosin fragments from flying fish and white marlin muscles was studied by means of absorbance changes resulting from aggregation at temperatures of 20°C to 70°C. Subfragment-1 (S-1) exhibited a high extent of interaction with the transition temperature of 35–36°C, while the interaction of heavy meromyosin (HMM) was very weak. Though light meromyosin (LMM) gave lower interaction values throughout the heating temperature, the addition of butanol promoted markedly the interactions at the temperature above 50°C. The degree of promotion was high for flying fish and low for white marlin.

Electrical properties of Sb2O3–CaO–V2O5 glasses and glass-ceramics

The d.c. conductivity (σ) of (a) glasses prepared by the press-quenching method and (b) glass-ceramics (crystallized glass) produced by post-heat treatment was investigated in the system Sb₂O₃–CaO–V₂O₅ and their conduction mechanism was studied. The glasses were n-type semiconductors with σ = 2.6 × 10^-6 ∼ 2.8 × 10^-5 S cm^-1 at 333 K for varying glass compositions. The conduction was attributed to small polaron hopping in the adiabatic regime. The estimated carrier density was 1.7 ∼ 3.8 × 10²¹ cm^-3 for V₂O₅ = 70 ∼ 80 mol% and the mobility was 3.5 × 10^-9 to 6.9 × 10^-8 cm² V^-1 s^-1. Crystallization raised the conductivity by a factor of 10³. The crystalline product in the glass-ceramics was Ca_0.17V₂O₅. The glass-ceramics were n-type semiconductors, and the conduction was interpreted by a superposition of the small polaron hopping in the crystalline and glassy phases. This revised version was published online in November 2006 with corrections to the Cover Date.     

Thermal Activation of Actomyosin Mg2+-ATPases from Flying Fish and Black Marlin Muscles

The effects of heat treatment (25°, 30°, 35°, 37°, and 40°C) on acto-myosin Mg²⁺-ATPase activity from flying fish and black marlin were studied with respect to setting of their meat pastes. The setting ability of flying fish had very high values but black marlin was low. Flying fish actomyosin Mg²⁺ATPase was activated more than three times by heating at 35°C, while the activation of black marlin was about two-thirds at 37°C. For acto-HMM ATPase, however, no appreciable difference in activation was observed between flying fish and black marlin. For both fishes, the acto-S-1 ATPase activities were not enhanced by the heat treatment. A possible role of myosin fragments in this activation is discussed.     

Thermal Activation of Actomyosin Mg-ATPases from Ordinary and Dark Muscles of Tuna and Sardine

Changes in activities of actomyosin, acto-heavy meromyosin (acto-HMM), and acto-subfragment-I (acto-S-I) ATPases from tuna and sardine due to heat treatment (20°, 25°, 30°, 35°, 40°C) were compared for ordinary muscle and dark muscle. Activation of ordinary muscle actomyosin Mg-ATPases was more than doubled for tuna and tripled for sardine by heating at 35°C, while activation of dark muscle actomyosin was not observed at any temperature. The occurrence of thermal activation corresponded to a rapid loss of the EDTA-ATPase activity. Activation of hybrid actomyosins from dark and ordinary muscles was dependent upon myosin. For acto-HMM and acto-S-I thermal activation was not observed. The role of myosin tail fragments in thermal activation is discussed.
