    Notes: Nondestructive analysis of water distribution and structural changes in cooked rice grains, Oryza sativa cv Koshihikari, was performed with Nuclear Magnetic Resonance (NMR) Micro imaging of protons (1H). Using a specially designed holder, high quality images of cooked rice grains were obtained, even when up to 10 grains were studied simultaneously. Internal hollows were observed in all examined cooked rice grains, and we propose a mechanism to explain their formation. The origin of these hollows was hypothesized to be cracks or fissures, and hollows resulted from sealing of such lacerations by gelatinized starch in the peripheral layer in combination with expansion of the grain during cooking.

    Notes: We previously reported that nuclear magnetic resonance (NMR) micro imaging detected the hollows in cooked rice but required a specialist to operate equipment. Convenient detection of hollows is useful in the characterization of cooked rice. X-ray imaging and light transmittance photography were studied as alternatives to NMR micro imaging. X-ray imaging detected about 50% of all hollows. Light transmittance photography detected almost all hollows in cooked rice (Oryza sativa cv. Koshihikari) effectively and rapidly, relatively quantifying hollow sizes and numbers.

    Notes: An interferometer previously developed for measuring instantaneous film thickness of the order of 10 μm–1 mm [T. Ohyama, K. Endoh, A. Mikami, and Y. H. Mori, Rev. Sci. Instrum. 59, 2018 (1988)] has been improved with respect to both facility of handling and accuracy of thickness determination. The improved version of the interferometer uses an expanded laser beam focused aslant on the subject film. The rays reflected from the front and rear surfaces of the film form interference fringes on a screen, which are then recorded in the form of a single snapshot interferogram or as a set of serial interferograms to be geometrically analyzed. Experiments with thin glass plates as sample films verified the expected advantages of the new version over the original one. The improved version of the interferometer was also tested on a liquid film asymptotically thinning as it drained down a vertical plate. The test indicated that the accuracy and precision of the new improved version far exceed those of other transient film-thickness measuring techniques. © 1996 American Institute of Physics.

    Notes: Calprotectin is a calcium binding protein produced by leukocytes, macrophages and epithelial cells, and its levels in several tissues increase during infections and in many inflamed areas, suggesting that it may be an indicator of inflammatory activity. Osteopontin is a prominent phosphorylated glycoprotein in bone matrix, having calcium binding capacity. Recently, it has been reported that calprotectin and osteopontin are present in urinary stones (pathological mineralized masses in the body), and that these proteins may be involved in their formation. Dental calculus formed by mineralization of dental plaque is an inflammatory factor which may contribute to periodontal disease. It contains many organic components involved in mineralization. We recently found osteopontin molecules in human dental calculus and suggested that the components of its matrix may be similar to those of urinary stones. In this study, we investigated the presence of calprotectin in human dental calculus by immunohistochemical and immunoblotting analyses using a specific antibody for calprotectin. After fixation and demineralization of dental calculi adhered to tooth roots, sections embedded in paraffin were immunoreacted with the antibody for calprotectin and positive immunostaining for calprotectin was observed. Dental calculus proteins were then extracted with EDTA and separated by electrophoresis on 15% polyacrylamide gels. By immunoblotting analysis, 3 or 4 bands were observed at 11, 14.5, 22–25, 28 or 36.5 kDa and these patterns corresponded to those of calprotectin subunits. When non-immune rabbit serum was used instead of calprotectin-specific antibody as a negative control, no immunoreactivity was observed. These findings indicate that calprotectin is associated not only with antibacterial action but also with calcium binding capacity during dental calculus formation.

    Notes: Abstract To elucidate adding effects of alginate (Alg) and its gelation on the reactivities of chymotrypsin (Chy), three kinds of Chy-immobilized capsules were prepared by an interfacial condensation, i.e., (a) a capsule containing only Chy in the core (Chy capsule), (b) a capsule containing Chy in NaAlg (Chy capsule(NaAlg)) and (c) a capsule containing Chy in CaAlg gel (Chy capsule(CaAlg)). The coated film was poly(ethylenediamine-terephthaloyl) (PEDT) and NaAlg in the core was gelled in the state adhered tightly to the PEDT film. These Chyimmobilizing capsules were found to be useful for determining the effects of the gelation around Chy. 4-nitrophenyl acetate was used as a substrate. From the rates of efflux of the product (p-nitrophenol), apparent maximum velocitiesv max and the apparent Michaelis constantsK′m were obtained. The values ofv′max showed the maximum at pH=7.8 for all three capsules and were found not to show any pH shift. The magnitude ofv′max was in the following order: Chy capsule (CaAlg) 〉 Chy capsule (NaAlg)-Chy capsule. The adding effects of Alg and its gelation on the reactivities of Chy are discussed.

    Notes: Abstract In La214, the electronic specific heat coefficient γ (=C el /T) is gradually suppressed with lowering T below a certain temperature T* (〉 T c ), where the in-plane resistivity ρ and magnetic susceptibility χ also tend to be suppressed slightly. Temperature T*, increasing with lowering x, is in qualitative agreement with the mean field T c (T co ), estimated from the superconducting gap amplitude 2Δ o at T ≪ T c , as the onset temperature T* of a pseudogap in Bi2212. The gradual suppression of γ below ∼ T co implies that a pseudogap will also open up below ∼ T co in La214 as in Bi2212. In underdoped samples, whose pseudogap-like behaviors in C el(T) become marked, the anomaly of C el around T c is rather different from the BCS expectation.

    Notes: Abstract Results for low temperature specific heat for single crystals of ladder/chain materials Sr 14−x Ca x Cu 24 O 41 (x= 0, 8, 10, 11.5) in magnetic field up to ∼15 T are reported. A sharp peak of the specific heat of a single crystal Sr 2.5 Ca 11.5 Cu 24 O 41, was found at ∼ 2.3 K, clearly indicating the onset of a long range order. In measurements of the specific heat in magnetic fields the transition temperature, T N , was found to shift to lower temperatures with increasing magnetic field, indicating that the ordering is antiferromagnetic, which has been confirmed by neutron scattering measurements. With decreasing x T N rapidly shifts to lower temperatures. For x=10 T N decreases to ∼ 1 K and for x= 0 no anomaly indicating the transition was found down to ∼ 0.6K
