The nucellar cells of navel orange(Citrus sinensis Osb. var. brasiliensis Tanaka) were successfully cryopreserved by vitrification. In this method, cells were sufficiently dehydrated with highly concentrated cryoprotective solution(PVS2) prior to direct plunge in liquid nitrogen. The PVS2 contains(w/v) 30% glycerol, 15% ethylene glycol and 15% DMSO in(More)
A stilbene synthase gene was isolated from three Vitis spp. (V. vinifera, V. labrusca and V. riparia). These genes were placed under the control of the cauliflower mosaic virus 35S promoter and introduced into kiwifruit (Actinidia deliciosa) plants by Agrobacterium-mediated gene transfer. The introduced gene(s) were expressed and piceid(More)
A simple and efficient gene transfer system of trifoliate orange (Poncirus trifoliata Raf.) was developed using epicotyl segments. The segments were infected with Agrobacterium harboring the binary vector pBI121 or pBI101-O12-p1. Both vectors contained the neomycin phosphotransferase II (NPTII) and the β-glucuronidase (GUS) genes. In the plasmid(More)
27 cases of cranioplasty with autogenous bone grafts stored in a deep-freezer and autoclaved before use are reported. The results of follow-up for an average period of one year were satisfactory from the standpoint of brain protection and cosmetic reconstruction. A small area of absorption of grafted bone was observed in two cases on the follow-up skull(More)
We compared the abundance of litter categories (coarse particulate organic matter 1–16 mm, leaves >16 mm, and small woody detritus 16–100 mm) and macroinvertebrate assemblages between natural litter patches in pools and riffles in a headwater stream. Litter patches in pools were formed under conditions of almost no current (<6 cm s−1), but in riffles they(More)
Enamel proteins were extracted from the newly formed layer of immature porcine enamel, and the 25 kDa amelogenin, 89 kDa enamelin and 13–17 kDa nonamelogenins were purified. Specific antisera were raised against these proteins. Antibodies specific to the C-terminal region (residues 149–173) of the 25 kDa amelogenin were generated by absorption of the(More)
Somatic hybrid plants of Rutaceae were obtained by protoplast fusion between Citrus sinensis Osb. (‘Trovita’ orange) and Poncirus trifoliata. Protoplasts isolated from embryogenic cells of C. sinensis and from leaves of P. trifoliata, and the culture of fusion products in the presence of high concentrations of sucrose were essential requirements for the(More)
It is imperative to understand the intraand perinodular hemodynamics of hepatocellular carcinoma (HCC) for precise imaging diagnosis and determination of treatment strategies. For this purpose, the combination of computed tomography (CT) and selective arteriography, such as CT during hepatic arteriography (CTHA) and CT during arterial portography (CTAP), is(More)
We purified a novel α-glucosidase to homogeneity from an Escherichia coli recombinant transformed with the α-glucosidase gene from thermophilic Bacillus sp. SAM1606. The enzyme existed as mono- and multimeric forms of a promoter protein with a relative molecular weight of 64,000 and isoelectric point of 4.6. We isolated a monomeric form of the enzyme and(More)
Recently a significant association of a missense mutation (Glu298Asp) of the endothelial nitric oxide synthase (NOS3) gene with late-onset Alzheimer's disease (LOAD) was reported. We tried to replicate this finding in a Japanese sample of 121 patients with LOAD, 51 with early-onset AD (EOAD), and 165 medical controls. However, the genotype and allelic(More)
