    Notes: This letter describes the memory effect of an AlGaAs/GaAs heterojunction field-effect transistor that contains InAs nanodots in the barrier layer. The device experiences a shift of threshold gate voltage, as a function of the amount of the electrons trapped in the nanodots. These trapped electrons can be injected by applying a positive gate voltage and be erased by a visible light illumination at negative gate bias. Although the shift of the threshold gate voltage volatilizes with the time after the memory programing operation, a considerable part of the shift is retained even after 100 h at room temperature. © 2000 American Institute of Physics.

    Notes: To construct an amplified-fragment length polymorphism (AFLP)-based molecular linkage map of zoysiagrass, the selfed progenies of a clone consisting of 78 individuals were analysed using 471 AFLP markers derived from 126 PstI/MseI primer combinations. Of these markers, 364 were grouped into 26 linkage groups. The maps covered a total length of 932.5 cM, with an average spacing of 2.6 cM between markers. This information proves useful for gene targeting, quantitative trait loci mapping, and marker-assisted selection in zoysiagrass.

    Notes: Background : Insufficient acid suppression is one of the main causes of proton pump inhibitor-refractory gastro-oesophageal reflux disease.Aim : To achieve more potent and long-lasting acid suppression, different dosage regimens of rabeprazole were compared in relation to the CYP2C19 genotype status.Methods : In a cross-over study, 18 healthy Helicobacter pylori-negative males (six homozygous extensive metabolizers, six heterozygous extensive metabolizers and six poor metabolizers) were given rabeprazole 10 mg once daily, 20 mg once daily or 10 mg twice daily, or water only (baseline data), for 7 days each. On day 7 of each regimen, 24-h intragastric pH-metry was performed.Results : No significant differences were observed in median pH values and pH 〉 4 holding time ratios between rabeprazole 10 mg once daily and 20 mg once daily. However, with rabeprazole 10 mg twice daily, these parameters were significantly higher than those with 20 mg once daily. The potency of acid suppression by rabeprazole was influenced by the CYP2C19 genotype status. The differences were somewhat significant but not large. The incidence of nocturnal acid breakthrough was lowest with rabeprazole 10 mg twice daily.Conclusions : Rabeprazole 10 mg twice daily, not 20 mg once daily, should be administered to achieve more potent and long-lasting acid suppression.

    Notes: Abstract Background. A prospective randomized study involving gastric cancer patients was undertaken to evaluate combined adjuvant chemotherapy and the prognostic value of biologic markers. Methods. One hundred and eighty-five patients under 75 years of age who underwent a curable resection of pathologic stage II or III gastric cancer were randomly assigned to receive adjuvant chemotherapy containing either: mitomycin C (MMC) plus oral 5-fluorouracil (FU) (MF), epirubicin plus oral FU (EF), or oral FU (F). Tumor tissue collected at surgery was immunohistochemically analyzed for p53 and proliferating cell nuclear antigen, and DNA ploidy was determined. Results. All prognostic factors were equally distributed in each arm. There was no significant difference among the groups in the 5-year overall survival. When the relationship between the biologic markers and prognosis was analyzed, the overall survival of all patients and stage III patients was poorer in those with p53 positivity, but the difference did not achieve significance. For patients with positive nodes, irrespective of the treatment regimen, p53-positivity was significantly associated with poorer prognosis (P = 0.05). In stage III patients, the survival of those with p53-positivity and DNA aneuploidy was significantly worse than that for patients with any other combination (P = 0.02). Conclusion. No survival benefit was observed with the combined chemotherapeutic regimens compared with FU alone. p53 positivity was negatively correlated to survival for node-positive and stage III patients.

    Aciculin and its relation to dystrophin: immunocytochemical studies in human normal and Duchenne dystrophy quadriceps muscles (2000)

    Notes: Abstract Aciculin is a novel adherens junction antigen extracted from human uterine smooth muscle that is reported to associate biochemically with dystrophin. We attempted to determine (i) the immunostainability of anti-aciculin antibody for the 6 histochemically normal human muscles and seven muscles from boys with Duchenne muscular dystrophy(DMD) and 11 disease control muscles, (ii) the ultrastructural localization of aciculin in normal skeletal myofibers, (iii) aciculin’s spacial relationship with dystrophin and β-spectrin, and (iv) if the aciculin is ultrastructurally colocalized with dystrophin, the distance from the aciculin epitope to the epitope of the dystrophin N- or C-terminal domain. For this, rabbit anti-aciculin antibody was generated against the synthetic peptide of aciculin fragment D [4]. Immunohistochemical staining showed that the immunostainability of DMD muscles for anti-aciculin antibody was markedly decreased as compared with normal and disease control muscles. Single and double immunogold labeling electron microscopy of 6 histochemically normal human quadriceps femoris muscles revealed that aciculin was present along the inner surface of muscle plasma membrane and that aciculin formed doublets more frequently with dystrophin (23.5 ± 1.8%; group mean ± SE) than with β-spectrin (12.8 ± 1.1%; P 〈 0.01 two tailed t test). Rabbit anti-aciculin antibody frequently formed doublets with monoclonal antibodies against the N- or C-terminal domain of dystrophin at the muscle cell surface. These results suggest that aciculin is associated with dystrophin and may interact with both the N- and C-terminal domains of dystrophin.

    Quantitative chromosome maps and rDNA localization in the T subgenome of Nicotiana tabacum L. and its putative progenitors (2000)

    Notes: Abstract  Using DAPI-stained prometaphase chromosomes, quantitative idiograms were constructed for the T subgenome of Nicotiana tabacum (2n = 4x = 48, SSTT) and two putative candidates for its T subgenome progenitor, Nicotiana otophora and Nicotiana tomentosiformis (both have 2n = 24, TT). The large chromosomes of the three karyotypes could be identified from the distributional pattern of the DAPI signal. Fluorescence in situ hybridization (FISH) with 5S rDNA gave not only good cytogenetical landmarks for identification of small chromosomes of the karyotypes but also phylogenetical information. In all three idiograms, 5S rDNA was localized in the proximal region of the long arm of a small submetacentric pair, but an additional 5S rDNA locus was detected terminally on the short arm of a small metacentric pair in N. otophora. The 18S rDNA locus detected here corresponded to satellite regions in all three karyotypes. Two satellited pairs in N. otophora and one satellited pair in N. tomentosiformis had single large subterminal DAPI blocks and two interstitial DAPI bands on their long arms, respectively. For the T subgenome component of N. tabacum, the single intense DAPI band was depicted on the center of the long arm of a satellited pair in the idiogram, although two interstitial bands were often detected on the long arm of the satellited pair in some spreads. Therefore, it was suggested that the T component of N. tabacum was more similar to that of N. tomentosiformis than N. otophora, especially in respect of the number and location of rDNA and the distributional patterns of DAPI signals.

    Description / Table of Contents: Zusammenfassung Hämatit aus Pyrophyllitlagerstätten des Shobara Distriktes, SW Japan Hämatit ist ein typisches Mineral in Liesegang-Gesteinen aus Pyrophyllitlagerstätten des Shobara Distriktes, südwestliches Japan. Dieses Mineral koexistiert mit feinkörnigem Pyrophyllit und Quarz, wobei die Hämatitkristalle charakteristischerweise nadel- bis faserförmig ausgebildet sind. Sie sind nur einige Mikrometer lang und sind im Reflexionsmikroskop daher nur bei starker Vergrößerung in Ölimmersion zu beobachten. Diese feinen Kristalle bilden ringförmige Aggregate mit mehreren Zehner-μm Durchmessern aus. Die Kristalle sind sehr oft radialstrahlig in diesen Ringen angeordnet. Mikrosondenuntersuchungen zeigen, dass die Hämatitkristalle fast reines Eisenoxid mit weniger als 0.9 Gew.% Ti sind. XRD Studien belegen, dass Hämatit das einzige Eisenmineral in den Liesegang-Gesteinen ist; d.h. es gibt keine Hinweise auf Fe-Hydroxide. Dies wird durch die Untersuchung des Wassergehaltes und IR Spektroskopie bestätigt.
    Notes: Summary Hematite is a characteristic mineral of Liesegang rock in the pyrophyllite ore deposits, Shobara district, southwestern Japan. The mineral intimately coexists with fine-grained pyrophyllite and quartz. The hematite crystals are characteristically needle-shaped to fibrous, and several microns in length, and can only be observed by high-magnification reflected light microscopy with oil immersion lens. They occur as ring-shaped aggregates several tens of microns in diameter. Moreover, the crystals are often arranged radially within the rings. Microprobe analyses reveal that hematite crystals are almost pure iron oxide, with less than 0.9 wt.% Ti. X-ray powder diffraction patterns and reflection intensities indicate that hematite is the only iron mineral in the Liesegang rock, i.e., no hydrous iron oxides are present. This observation was also confirmed by examinations of water content and infrared spectroscopy.
