    Notes: Summary Previous studies indicated two types of phenotypic protein markers as two minor bands of SDS-PAGE for rice storage protein. A variant derived from a Pakistani variety, Dular, was found to show a mobility variant with Band 11, a relatively faster-moving band as compared to Band 10, while most of the other cultivated rices exhibited Band 10 at a molecular weight of around 100–110 K. Band 11 was also observed in several wild rice species. How this variant occurred is not known. Another marker is characterized by the presence of either Band 56 (slower-migrating band) or Band 57 (faster-migrating band) in most cultivars at a molecular weight of about 28–27 K. Most indica varieties developed in Taiwan have Band 57 and japonica varieties have Band 56. Genetic analysis of F1, F2 and F3 seeds from interstrain crosses indicated that Band 10 versus Band 11 and Band 56 versus Band 57 are due to codominant alleles at two loci. Tests of independent inheritance between these two loci (Band 10/11 versus Band 56/57) indicated that there is no linkage between them. Both of these two protein loci encode for endosperm proteins and mostly belong to the minor polypeptide subunits of the glutelin fraction of rice seed proteins. Studies on reciprocal crosses indicate dosage effects as exhibited in band patterns. Variations in band intensity were frequently observed when the maternal genotype was different.

    Observed regional distribution of sulfur dioxide in Asia (1995)

    Notes: Abstract SO2 concentrations have been measured for one year at forty-five locations throughout Asia using passive samplers. Duplicate samples were exposed at each site for one month intervals. The sites were selected to provide background information on the distribution of SO2 over wide geographical regions, with emphasis on the regional characteristics around areas estimated to be sensitive to sulfur deposition. The annual mean values ranged from less than 0.3 μg/m3 at Tana Rata, located at 1545 m on the Malaysia Peninsula, Lawa Mandau, (Borneo) Malaysia, and Dhankuta, Nepal, to values greater than 20 μg/m3 at Luchongguan (Guiyang) China, Babar Mahal, Nepal, and Hanoi, Vietnam. In general high concentrations were measured throughout China, with the highest concentrations in the heavy industrial areas in Guiyang. The concentrations in east Asia around the Korea peninsula were ∼5 μg/m3. The concentrations in the southeast Asia tropics were low, with no station in Malaysia and Indonesia having average concentrations exceeding 1.7 μg/m3. The observed SO2 concentrations were found to display a distinct seasonal cycle which is strongly influenced by the seasonality of winds and precipitation patterns.

    Mössbauer study of melt-spun Sm20Fe70Ti10 alloy (1992)

    Notes: Abstract The rapidly queoching samples of Sm20Fe70Ti10 were prepared by melt spinning. The coercivities of crystallized ribbons were found to vary with the spinning velocity. The value of coercivity obtained was 3.2kOe, which is higher than that reached in Sm−Fe−Ti alloys with the ThMn17 structure. The results of Mössbauer effect and X ray diffraction analyses indicate that the alloy consists of SmFe2, SmFe3, an undetermined paramagnetic phase and the minor phase of Sm2Fe17.

    Reservoir-induced Seismicity in China (1998)

    Notes: Abstract —A review of case histories of reservoir-induced seismicity (RIS) in China shows that it mainly occurs in granitic and karst terranes. Seismicity in granitic terranes is mainly associated with pore pressure diffusion whereas in karst terranes the chemical effect of water appears to play a major role in triggering RIS. In view of the characteristic features of RIS in China, we can expect moderate earthquakes to be induced by the construction of the Three Gorges Project on the Yangtze River.

    Menadione-induced cytotoxicity to rat osteoblasts (1997)
    Springer

    Notes: Abstract. Oxygen-derived free radical injury has been associated with several cytopathic conditions. Oxygen radicals produced by chondrocytes is an important mechanism by which chondrocytes induce matrix degradation. In the present study, we extend these observations by studying oxidative processes against osteoblasts. Osteoblasts were mixed in in vitro culture with 200 μM menadione. The cytotoxic effect of menadione-induced oxidative stress was monitored by lucigenin- or luminol-amplified chemiluminescence, tetrazolium assay and immunocytochemical study. Results showed that adding menadione induces an oxidative stress on osteoblasts, via superoxide and hydrogen peroxide production, that can be eradicated by superoxide dismutase (SOD) and catalase in a dose-dependent manner. Catalase and the appropriate concentration of dimethyl sulfoxide have a protective effect on cytotoxicity induced by menadione, whereas SOD does not. Menadione-treated osteoblasts have a strong affinity for annexin V, and the nuclei are strongly stained by TUNEL (TdT-mediated dUTP nick-end labelling). The results suggest that menadione-triggered production of reactive oxygen species leads to apoptosis of osteoblasts.

    Electrophysiological Study of Chimeric Sodium Channels from Heart and Skeletal Muscle (1998)
    Springer

    Notes: Abstract. The α-subunit cDNAs encoding voltage-sensitive sodium channels of human heart (hH1) and rat skeletal muscle (rSkM1) have been expressed in the tsA201 mammalian cell line, in which inactivation properties appear to be normal in contrast to Xenopus oocytes. A series of rSkM1/hH1 chimeric sodium channels has been evaluated to identify the domains of the α-subunits that are responsible for a set of electrophysiological differences between hH1 and rSkM1, namely, midpoints and slope factors of steady-state activation and inactivation, inactivation kinetics and recovery from inactivation kinetics and their voltage-dependence. The phenotype of chimeric channels in which each hH1 domain was successively introduced into a rSkM1 α-subunit framework confirmed the following conclusions. (i) The D4 and or/C-ter. are responsible for the slow inactivation of hH1 sodium channels. (ii) Concerning the other differences between rSkM1 and hH1: steady-state activation and inactivation, kinetics of recovery from inactivation, the phenotypes are determined probably by more than one domain of the α-subunit.

    Distribution of ADH2 and ALDH2 genotypes in different populations (1992)

    Human genetics 〈Berlin〉 88 (1992), S. 344-346

    Topics: Biology , Medicine
    Notes: Summary The distribution of the human liver alcohol dehydrogenase, ADH2, and aldehyde dehydrogenase, ALDH2, genotypes in 21 different populations comprising Mongoloids, Caucasoids, and Negroids was determined by hybridization of the amplified genomic DNA with allele-specific oligonucleotide probes. Whereas the frequency of the ADH 1 2 allele was found to be relatively high in the Caucasoids, Mexican Mestizos, Brazilian Indios, Swedish Lapps, Papua New Guineans and Negroids, the frequency of the ADH 2 2 gene was considerably higher in the Mongoloids and Australian Aborigines. The atypical ALDH2 gene (ALDH22) was found to be extremely rare in Caucasoids, Negroids, Papua New Guineans, Australian Aborigines and Aurocanians (South Chile). In contrast, this mutant gene was found to be widely prevalent among the Mongoloids. Individuals possessing the abnormal ALDH2 gene show alcohol-related sensitivity responses (e.g. facial flushing), have the tendency not to be habitual drinkers, and apparently suffer less from alcoholism and alcohol-related liver disease.

    S-Induced Destabilization of Aluminum Oxide at the Fe(poly)–S–Al2O3 Interface (2000)
    Springer

    Notes: Abstract Auger measurements reveal that, under UHV conditions, interfacial sulfurinduces the destabilization of an aluminum oxide overlayer at theFe–Al2O3 interface at temperatures above400 K. One monolayer deposition of Al onto Fe/S results in the insertion ofAl at the Fe–S interface. Exposure of Fe–Al–S to oxygenat 300 K gives rise to the complete oxidation of the aluminum adlayer asevidenced by the disappearance of the Al0 Auger signal and thestoichiometric formation of the aluminum oxide. When the resultingFe–S–Al2O3 is annealed progressively tohigher temperatures between 400 and 900 K, analysis of the Auger spectrashows a dramatic decline in the Al/O Auger intensity ratio. This declineis accompanied by the appearance of a small signal due to Al0,which maintains a constant intensity as the total Al signal (due mainly toAl3+) decreases. The appearance of the Al0 Augersignal accompanied by the attenuation of the Al3+ signalsignifies the chemical conversion of Al3+ into Al0,probably followed by diffusion of Al into the bulk. The possibility ofalumina dewetting and island formation, however, cannot be ruled out onthe basis of the present data. In the absence of interfacial sulfur, the alumina–Fe interface is stable to 900 K.
