The primary objective to these study was to test NPKCaMg-fertilization induced ＂Zn（2＋）＂ bioavailability in triticale rhizosphere soils. Soil and plant samples were taken from experimental sites randomly, and were analysed in laboratory to plant available Zn^2＋） content. Zinc ＂Zn（2＋）＂ concentrations showed a large variability to interactions with soil＇s pH values. It ranged from 0.4 and 1.36 mg kg1. Soil＇s ＂Zn（2＋）＂ contents had been significantly lower than International Soil Limit （ISL） value （70 mg kgl）, consequently. Plant available ＂Zn（2＋）＂ contents from triticale rhizosphere soils in Leaf＋Straw ranged from 10.1 to 38.4 mg kgl, and in Seed from 26.9 to 52.0 mg kg1. ＂Zn（2＋）＂s Actual Translocation Index （ATI） from rhizosphere soils to Leaf＋Straw had as average 23.6, and to grain 43. 1. ＂Zn（2＋）＂ Leaf＋Straw bioacummulation （g hal） had as average 13.4, Grain 23.2, and total （Leaf＋Straw＋Grain） 36.6. ＂Zn（2＋）＂translocation from soils to Leaf＋Straw was 37% lower than to Grain. Ultimately, within the range of experimental conditions tested these results are present that ＂Zn（2＋）＂ tends to accumulate to triticale organs to create the conditions for toxicity effects in Food Chane.

Abstract The voltage-gated Na＋ channel subtype Nav1.7 is important for pain and itch in rodents and humans. We previously showed that a Nav1.7-targeting monoclonal antibody （SVmab） reduces Na＋ currents and pain and itch responses in mice. Here, we investigated whether recom- binant SVmab （rSVmab） binds to and blocks Nav1.7 similar to SVmab. ELISA tests revealed that SVmab was capable of binding to Nav1.7-expressing HEK293 cells, mouse DRG neurons, human nerve tissue, and the voltagesensor domain II of Nav1.7. In contrast, rSVmab showed no or weak binding to Nav1.7 in these tests. Patch-clamp recordings showed that SVmab, but not rSVmab, markedly inhibited Na＋ currents in Nav1.7-expressing HEK293 cells. Notably, electrical field stimulation increased the blocking activity of SVmab and rSVmab in Nav1.7- expressing HEK293 cells. SVmab was more effective than rSVmab in inhibiting paclitaxel-induced mechanical allodynia. SVmab also bound to human DRG neurons and inhibited their Na＋ currents. Finally, potential reasons for the differential efficacy of SVmab and rSVmab and future directions are discussed.

Clusterin, a protein associated with multiple functions, is expressed in a wide variety of mammalian tissues. Although clusterin is known to be involved in neurodegenerative diseases, ageing, and tumorigenesis, a detailed analysis of the consequences of gain- or loss-of- function approaches has yet to be performed to understand the underlying mechanisms of clusterin functions. Since clusterin levels change in neurological diseases, it is likely that clusterin contributes to cell death and degeneration in general. Zebrafish was investigated as a model system to study human diseases. During development, zebrafish clusterin was expressed in the notochord and nervous system. Embryonic overexpression of clusterin by mRNA microinjection did not affect axis formation, whereas its knock-down by anti-sense morpholino treatment resulted in neuronal cell death. To analyze the function of clusterin in neurodegeneration, a transgenic zebrafish was investigated, in which nitroreductase expression is regulated under the control of a neuron-specifc huC promoter which is active between the stages of early neuronal precursors and mature neurons. Nitroreductase turns metronidazole into a cytotoxic agent that induces cell death within 12 h. After metronidazole treatment, transgenic zebrafish showed neuron-specific cell death. Interestingly, we also observed a dramatic induction of clusterin expression in the brain and spinal cord in these fish, suggesting a direct or indirect role of clusterin in neuronal cell death and thus, more generally, in neurodegeneration.

The search operation of spatial data was a principal operation in existent spatial database management system, but the update operation of spatial data such as tracking are occurring frequently in the spatial database management system recently. So, necessity of concurrency improvement among transactions is increasing. In general database management system, many techniques have been studied to solve concurrency problem of transaction. Among them, multi version algorithm does to minimize interference among transactions. However, to apply existent multi version algorithm to improve concurrency of transaction to spatial database management system, the waste of storage happens because it must store entire version for spatial record even if only aspatial data of spatial record is changed. This paper has proposed the record management techniques to manage separating aspatial data version and spatial data version to decrease waste of storage for record version and improve concurrency among transactions.

Using Ti and biphasic calcium phosphate (BCP) pow-ders, Ti-Ca-P composites which contained 0 - 30 vol.% BCP powders initially, were fabricated by vac-uum sintering at two different sintering temperatures, 1300°C and 1400°C. Detailed microstructural char-acteristics of the resulting composites were investi-gated. Mechanical properties like compressive strength, Vickers hardness were evaluated and they showed decreasing trend with the increasing initial BCP content. The x-ray diffraction (XRD) profiles revealed that extensive chemical reaction occurred and the initial BCP was degraded and formed CaO, TiO2, TiP, CaTiO3. However, the cell viability by MTT assay and cell proliferation behavior through one cell morphology analysis showed excellent in-creasing trend in biocompatibility which makes this materials suitable for hard tissue aid *** the composite containing 30 vol.% BCP content with Ti sintered at 1400°C showed excellent biocompati-bility with the Vickers Hardness value 108.8 HV and the compressive strength value 303.7 MPa.
