    Elemental analyses of autoradiographic grains by X-ray microanalysis (1977)
    Springer
    Cellular and molecular life sciences 33 (1977), S. 440-441 
    Details
    ISSN: 1420-9071
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary Electron probe X-ray microanalysis has revealed that the autoradiographic grains obtained by high resolution electron microscopic autoradiography contain deposits of lead, silicon and chlorine in addition to silver grains. These results suggest the necessity for the confirmation of the autoradiographic grains by ancillary techniques.

    Distribution of H3-dimetacrine in rat cerebral cortex by electron microscopic autoradiography (1976)
    Springer
    Cellular and molecular life sciences 32 (1976), S. 1306-1308 
    Details
    ISSN: 1420-9071
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The cellular distribution of H3-dimetacrine in rat cerebral cortex was studied by electron microscopic autoradiography. A considerable proportion of autoradiographic grains (40.6%) was located over the synaptic areas, while the other structures (i.e., dendrites, axons, glial and neuronal cells) contained less autoradiographic activity.

    5-Hydroxytryptamine binding to butanol extracts from myelin fragments (1977)
    Springer
    Cellular and molecular life sciences 33 (1977), S. 932-933 
    Details
    ISSN: 1420-9071
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary The myelin fraction of rat brain stem was treated with butanol-water mixtures, and the extracted proteolipids were separated by Sephadex LH20 column chromatography. 2 peaks of proteolipids eluted in chloroform-methanol 4/1 showed the binding capacity for C14·5-HT. This finding suggests the necessity of the more careful investigations for the probability of proteolipids as receptor proteins in the central nervous system.

    Butanol extracts from myelin fragments. IV. Some interactions between 5-hydroxytryptamine and other neurotransmitters binding (1978)
    Springer
    Cellular and molecular life sciences 34 (1978), S. 1628-1629 
    Details
    ISSN: 1420-9071
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Summary To examine the interaction between 5-HT and other neurotransmitters binding to the butanol extracts from myelin, double labelling experiments were done. The binding peaks of C14. ACh and NA were clearly different from that of H3. 5-HT. At 5×10−7 M, binding of 5-HT, ACh, NA, GABA and DA was 62.7, 2.3, 7.0, 5.8 and 1.9 nmoles/mg protein, respectively. These results suggest that the 5-HT binding components of myelin butanol extracts may have high selectivity and specificity.

    Extracellular processing of dentin matrix protein in the mineralizing odontoblast culture (1995)
    Springer
    Calcified tissue international 57 (1995), S. 237-241 
    Details
    ISSN: 1432-0827
    Keywords: Odontoblast ; Dentin ; Mineralization ; Casein kinase II ; Phosphophoryn
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine , Physics
    Notes: Abstract Odontoblasts that we prepared from bovine incisors produced a dentin-specific protein, phosphophoryn, and accumulated it in mineralized nodules. The time course of mineralization was detected by measuring osteocalcin and mineral in the nodules. The sequence of developmental expression of proteins in this mineralizing dentin cell culture is very similar to that in bone cells, suggesting a common mechanism for matrix mineralization in bone and dentin. Casein kinase II, which phosphorylates bone phosphoproteins and dentin phosphophoryn, also emerges coinciding with the initiation of mineralization. Furthermore, we have detected extracellular phosphorylation by casein kinase II of a dentin protein of Mr 60,000, which we recovered from the phosphophoryn fraction in CaCl2 precipitate.

    Bioactivity of sol–gel derived organically modified silicates: Part I: In vitro examination (1997)
    Springer
    Journal of materials science 8 (1997), S. 157-161 
    Details
    ISSN: 1573-4838
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine , Technology
    Notes: Abstract Bioactivity was investigated for several organically modified silicates (Ormosils) prepared through sol–gel processes. Ca(II)-free samples were biocompatible only, but Ca(II)containing samples were bioactive and deposited apatite during immersion in a simulated body fluid. The ease of silanol (Si–OH) group formation on the ormosils was considered a predominant factor controlling the bioactivity, while the effect of dissolved Ca(II) ions to increase the degree of supersaturation in the simulated body fluid is secondary.

    Electron microscopic and light scattering observation on a system with two iridescent phases (1994)
    Springer
    Colloid & polymer science 272 (1994), S. 604-611 
    Details
    ISSN: 1435-1536
    Keywords: Electron microscopy ; light scattering ; dodecyldimethylaminoxide/hexanol/water ; iridescent phase ; bicontinuous sponge phase ; vesicle phase

    Notes: Abstract Electron microscopic observations and classical light-scattering measurements have been carried out for dodecyldimethylaminoxide/hexanol/water mixtures in the concentration range where iridescent colors occur. This system has two different iridescent phases. The iridescent phase with more hexanol forms quickly, and the phase with less hexanol forms very slowly. Three different isotropic phases which show strong flow birefringence are found near both iridescent phases. The electron microscopic pictures show clearly that only one of these isotropic phases with strong flow birefringence is a bicontinuous sponge phase (L3h -phase). This is the phase which comes out by adding some alkanol to the upper lamellar phase. The flow birefringent phase below the lower lamellar phase forms unilamellar vesicles. The flow birefringent phase which occurs between both iridescent phases contains multilamellar vesicles and is shown to be a precursor of a lamellar phase.

    Ormosil coatings of high hardness (1995)
    Springer
    Journal of materials science 30 (1995), S. 2566-2570 
    Details
    ISSN: 1573-4803
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract Organically modified silicates (ormosils) of two systems were coated on polyethyleneterephthalate (PET) substrates. One was the tetraethoxysilane (TEOS)-vinyltriethoxysilane (VTES) system and the other was the TEOS-tetraisopropyltitanate (TIPT)-VTES system. The reactions among the alkoxides were examined by liquid state 29Si nuclear magnetic resonance (NMR) spectroscopy. The chemical bonds between TEOS and VTES, between TEOS and TIPT, and between VTES and TIPT are shown in the spectra and the reaction schemes are proposed. Vickers hardnesses of the ormosil coatings were obtained by using the models developed by Jönsson and Hogmark, and the theoretical models developed by the authors were valuable to predict the hardness values. The ormosil coatings obtained in the present study were much harder than the hardest transparent plastics, and thus are very useful for hard or protective coatings on organic polymers.

    Molecular cloning of a novel human gene (SIRP-B2) which encodes a new member of the SIRP/SHPS-1 protein family (2000)
    Springer
    Journal of human genetics 45 (2000), S. 378-382 
    Details
    ISSN: 1435-232X
    Keywords: Key words SIRP ; SHPS-1 ; Glycoprotein ; Chromosome 20p13 ; RH mapping
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology , Medicine
    Notes: Abstract A full-length cDNA encoding a novel protein was isolated and sequenced from a human placental cDNA library. This cDNA consists of 1735 base pairs and has a predicted open reading frame (ORF) encoding 354 amino acids. It possesses a putative signal sequence, a long extracellular domain, a transmembrane region, a short intracellular domain, and no catalytic domain, which is highly homologous to signal-regulatory protein (SIRP)-β, suggesting that it seems to be a new member of the SIRP family. Polymerase chain reaction (PCR)-based mapping with both a monochromosomal hybrid panel and radiation hybrid cell panels placed the gene to human chromosome 20p13 near the marker D20S906.
