新聞紙の古紙に1級アミノ基を化学修飾により固定化することにより, 金属イオンの吸着剤に調製した。元素分析の結果より, このゲルは4.1mol/kgもの高い割合の官能基を有することがわかった。所定のpH領域からの銅 (II) やクロム (VIおよびIII) 等の卑金属の吸着, および塩酸からの金 (III) , パラジウム (II) および白金 (IV) のような貴金属の吸着を調べ, 市販の弱塩基性陰イオン交換樹脂のそれと比較した。pH領域からの卑金属の吸着の選択性の順序は銅 (II) >クロム (VI) >鉄 (III) ≫亜鉛 (II) >クロム (III) の順であった。一方, 塩酸中からは, 金 (III) , 白金 (IV) およびパラジウム (II) は全塩酸濃度範囲において定量的に吸着されたのに対して, 鉄 (III) や亜鉛 (II) は全く吸着されなかった。このゲルの貴金属に対する選択性は陰イオン交換樹脂のそれよりも高いことが明らかとなった。パラジウム (II) , 白金 (IV) および銅 (II) に対する飽和吸着量はそれぞれ1.6, 1.1および0.48mol/kgであった。
Highly Conductive Carbon Fiber Reinforced Concrete for Icing Prevention and Curing (2016)

This paper aims to study the feasibility of highly conductive carbon fiber reinforced concrete (CFRC) as a self-heating material for ice formation prevention and curing in pavements. Tests were carried out in lab ambient conditions at different fixed voltages and then introduced in a freezer at -15 °C. The specimens inside the freezer were exposed to different fixed voltages when reaching +5 °C for prevention of icing and when reaching the temperature inside the freezer, <i>i.e.</i>, -15 °C, for curing of icing. Results show that this concrete could act as a heating element in pavements with risk of ice formation, consuming a reasonable amount of energy for both anti-icing (prevention) and deicing (curing), which could turn into an environmentally friendly and cost-effective deicing method.
Behavior of Endothelial Cells Cultured on Silastic and Dacron Velour Under Flow Conditions <i>In Vitro</i>: Implications for Prelining Vascular Grafts with Cells (1983)

Tissue-cultured bovine aortic endothelial cells were subjected to flow in an in vitro circulatory loop designed to simulate the flow and pressure conditions in the aorta. The cells were cultured under stationary conditions on tubes of fibronectin-coated Silastic or of Dacron velour. The tubes were then added to the flow loop, which circulated complete tissue culture medium in a pulsatile mode. Light microscopy and cell counts showed that the cells not only remained adherent for up to 2 weeks under flow conditions, but also underwent hypertrophy and proliferation in response to the flow regimen.

Squamous Cell Carcinoma Arising in a Lymphangioma of the Tongue (2002)

Lymphangioma of the tongue is a rare, benign malformation of the lymphatic channels. The clinical course is characterized by multiple recurrences after local excision. A review of the literature revealed no prior association of a head and neck lymphangioma with squamous cell carcinoma (SCC). We present the case of a 64‐year‐old woman with a history of a tongue base lymphangioma who developed a base of tongue SCC. Further confounding the pathophysiologic scenario was a history of nasopharyngeal irradiation for adenoid hypertrophy.
Resonator self-temperature-sensing using a dual-harmonic-mode crystal oscillator (2003)

A thermometry method using resonator self-temperature-sensing is described. The method uses a harmonically related pair of c-modes of an SC-cut that is simultaneously excited in a dual-mode oscillator, and then combined to produce a thermometric frequency having a monotonic and nearly linear dependence on temperature. It avoids the activity dip problems of the b-mode and overcomes limitations of using external sensors that are subject to thermal lab and temperature gradients. This method provides a means of measuring resonator temperature with high accuracy, limited only by the stability difference between the c-mode frequencies. The concept for this dual c-mode thermometry method is presented and its implementation in a microcomputer-compensated crystal oscillator discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
A user-friendly diffraction modeling program (2002)

Optical data storage systems require a great deal of sophistication in their design and analysis. It is often necessary to simulate portions of the optical system with ray tracing or diffraction modeling. This paper introduces a new program called OPTISCAN that operates in the MATLAB/sup TM/ language environment. OPTISCAN combines many of the routines we have developed over the last several years for modeling optical data storage systems and other applications, as well as some new capabilities, In addition to its powerful simulation capabilities, OPTISCAN solves a common problem with simulation codes. Often it takes a significant amount of time for a student or engineer to learn how to use either in-house or commercial programs. A unique aspect of OPTISCAN is its graphical user interface (GUI) that makes programming much less complicated and makes OPTISCAN easy to use. This paper describes the GUI with a simple example. An optical disk application is also described.
Advanced multi-layer ceramic surface-mount functional components for telecommunications equipment (2002)

We have developed various kinds of miniatured chip-type ceramic monolithic electronic components such as chip LC filters, hybrid couplers and delay lines, using low temperature cofireable ceramics (LTCC) with copper inner electrodes. The outer electrodes are also made of copper plated by Ni and Sn. Based on such LTCC multilayering technologies, our advanced microwave circuit design technologies have recently developed a chip RF diode switch and such a switch with integrated low-pass filter in a small (6.7/spl times/5.0/spl times/3.0 mm in production, 5.4/spl times/4.0/spl times/2.8 mm under development), surface-mountable package. Those devices employ the monolithic ceramic substrate, which includes relevant passive elements in it, with copper inner electrodes and copper outer/surface electrodes plated by Ni and Au. This paper discusses related ceramic material systems, manufacturing process, circuit design technologies and operating parameters of those chip RF diode switches.
Antibodies in Cardiovascular Diagnosis and Therapy (1986)

The vast potential of antibodies as diagnostic and therapeutic agents is emerging on several medical fronts. Of several applications in cardiology, two are being explored at the level of clinical investigation: the treatment of lethal digitalis intoxication and the use of myosin-specific antibodies for detection and early visualization of acute myocardial infarction.
Methods for fine-tuning the wavelength response of single-mode optical-fibre taper filters (1987)

The effect of twisting and longitudinal strain on the wavelength response of taper coaxial coupler filters is examined. Both effects permit the fine-tuning of the wavelength response of the single fibre filters, but we demonstrate that a combination of twist and strain is preferred, as it is possible to eliminate residual birefringence present during the fabrication of such filters.
Structure and regulation of the AMP nucleosidase gene (amn) from Escherichia coli (1989)

The gene for AMP nucleosidase from Escherichia coli (amn) has been sequenced and characterized. The gene codes for a transcript of 1.7 +/- 0.2 kb, and the open reading frame corresponds to a protein of 483 amino acids (Mr = 53848). Amino acid sequences from tryptic peptides of AMP nucleosidase, N-terminal amino acid analysis, and the amino acid composition confirm the gene assignment and the open reading frame of amn. Primer extension studies determined the 5'-end of the amn transcript. The 5'-regulatory region contains overlapping sequences with similarity to the consensus sequences for binding cAMP receptor protein and inorganic phosphate repressor protein. Addition of exogenous cAMP to E. coli deficient in adenylate cyclase resulted in a 3-fold increase in AMP nucleosidase activity. Growth of E. coli on limiting phosphate resulted in an 8-fold increase in the production of AMP nucleosidase. The amn gene was expressed in AMP nucleosidase deficient strains of Azotobacter vinelandii and E. coli. A pUC-amn construct is described that causes approximately 20% of the total protein in E. coli to be produced as AMP nucleosidase. Comparison of the amino acid sequence for AMP nucleosidase with that for yeast AMP deaminase indicates a region in which six of eight amino acids are identical but no other overall homology. The amino acid sequence showed poor agreement with consensus sequences for adenylate binding sites even though the enzyme is known to have a catalytic site for AMP and regulatory sites for MgATP and phosphate.
94 GHz zonal ring reflector for helicopter collision avoidance (2004)

A single-layer reflector antenna combining eight and four correcting Fresnel zones is presented. The progressive phase shift is achieved by circular and annular patches. The choice of a quarter-wavelength thickness substrate provides naturally 0 and 180° correcting zones that simplify the reflector design. A prototype of reflector antenna working at 94 GHz has been designed, built and measured. Measurement results show 70% improvement of antenna aperture efficiency compared to the half-wave Fresnel zone plate reflector .
Sculptured Layer‐by‐Layer Films (2007)

Sculptured freely suspended layer-by-layer (LbL) films with microscopic periodic modulations of refractive properties are reported. The modulated refractive properties are achieved by the topological variation of the film shape, which generates optical diffraction effects with bright structural colors and optical grating properties. An LbL assembly on a sacrificial microimprinted substrate is employed to generate such a sculptured LbL structure with an effective thickness of 60 nm and a 160 nm peak-to-peak modulation.

Structural, microstructural and magnetic evolution in cryo milled carbon doped MnAl (2018)

The low cost, rare earth free τ-phase of MnAl has high potential to partially replace bonded Nd<sub>2</sub>Fe<sub>14</sub>B rare earth permanent magnets. However, the τ-phase is metastable and it is experimentally difficult to obtain powders suitable for the permanent magnet alignment process, which requires the fine powders to have an appropriate microstructure and high τ-phase purity. In this work, a new method to make high purity τ-phase fine powders is presented. A high purity τ-phase Mn<sub>0.55</sub>Al<sub>0.45</sub>C<sub>0.02</sub> alloy was synthesized by the drop synthesis method. The drop synthesized material was subjected to cryo milling and followed by a flash heating process. The crystal structure and microstructure of the drop synthesized, cryo milled and flash heated samples were studied by X-ray in situ powder diffraction, scanning electron microscopy, X-ray energy dispersive spectroscopy and electron backscatter diffraction. Magnetic properties and magnetic structure of the drop synthesized, cryo milled, flash heated samples were characterized by magnetometry and neutron powder diffraction, respectively. The results reveal that the 2 and 4 hours cryo milled and flash heated samples both exhibit high τ-phase purity and micron-sized round particle shapes. Moreover, the flash heated samples display high saturation magnetization as well as increased coercivity.
Rapid detection of pathogenic leptospires by lyophilized reagent-based polymerase chain reaction. (2011)

A simple and reliable tool for the early diagnosis of leptospirosis is urgently needed. We report the development of a lyophilized reagent-based polymerase chain reaction (PCR) assay targeting lipL32 gene, which is present only in pathogenic leptospires. To determine the effectiveness of the newly developed assay in the early diagnosis of leptospirosis, the sensitivity and specificity was evaluated. In simulated clinical samples, the assay was able to detect 10² and 10³ leptospires/ml in spiked urine and blood samples, respectively. In experimentally infected animals, leptospiral DNA could be detected in blood and lung samples as early as Day 1 post infection. This assay was also shown to be stable and remained sensitive for up to five months at ambient temperature. Hence, this lyophilized reagent-based PCR assay with high specificity, sensitivity and stability would provide a simple, rapid and reliable method in diagnosing acute leptospirosis, especially in the field of veterinary medicine.
Asialoglycoprotein Receptor (ASGP-R) is Liver Parenchymal Cells is Involved in Elimination of Recombinant Human TFPI (2010)

We here report on a study carried out to determine the early clearance kinetics, and organ, cell(s) and receptor(s) responsible for the clearance of full length TFPI purified from BHK cells (TFPI<sup>BHK</sup>). Following intravenous administration, <sup>125</sup>I-TFPI<sup>BHK</sup> was cleared with a\nbiphasic elimination curve, and with a significantly slower t<sub>1/2</sub>α compared to recombinant human TFPI from <i>E.Coli</i> (TFPI<sup>E.Coli</sup>) (1.95±0.10 versus 1.42±0.07 min, respectively, p<0.001). Studies on organ and cell distribution revealed that liver parenchymal cells (PCs) were responsible for 96% of the uptake of TFPI<sup>BHK</sup> and 81% of TFPI<sup>E.Coli</sup>, whereas the nonparenchymal cells (NPCs) were responsible for 4% and 19%, respectively. Pre-administration of excessive amounts of unlabeled TFPI<sup>BHK</sup> prolonged blood clearance of <sup>125</sup>I-TFPI<sup>BHK</sup>. Unlabelled TFPI<sup>BHK</sup> inhibited endocytosis of <sup>125</sup>I-TFPI<sup>BHK</sup> in PCs <i>in vitro</i>, whereas blocking\nof LDL-receptor related protein-1 (LRP-1) by receptor-associated protein (RAP) affected\nneither blood clearance nor endocytosis of <sup>125</sup>I-TFPI<sup>BHK</sup> in PCs. In addition, TFPI<sup>BHK</sup> was also\nfound in the kidneys and this could be reduced in the presence of RAP. Asialoorosomucoid (ASOR), a potent inhibitor of the asialoglycoprotein receptor (ASGP-R), prolonged the circulatory survival of <sup>125</sup>I-m-TFPI by 1.5-fold (p<0.001). <i>In vitro</i>, ASOR and other ASGP-R antagonists significantly inhibited endocytosis of <sup>125</sup>I-TFPI<sup>BHK</sup> in PCs. Moreover, unlabelled TFPI<sup>BHK</sup> markedly decreased endocytosis of <sup>125</sup>I-asialofetuin. In conclusion, our findings\nsuggest that ASGP-R mediated endocytosis in the liver is involved in the clearance of\nTFPI<sup>BHK</sup>.

The book describes in clear language an especially broad range of uses to which circuit simulation principles may be put-from running general applications, to understand why SPICE works in some cases and not in others.
Expression of a dominant allele of human ARF1 inhibits membrane traffic in vivo (1994)

ADP-ribosylation factor (ARF) proteins and inhibitory peptides derived from ARFs have demonstrated activities in a number of in vitro assays that measure ER-to-Golgi and intra-Golgi transport and endosome fusion. To better understand the roles of ARF proteins in vivo, stable cell lines were obtained from normal rat kidney (NRK) cells transfected with either wild-type or a dominant activating allele ([Q71L]) of the human ARF1 gene under the control of the interferon-inducible mouse Mx1 promoter. Upon addition of interferon, expression of ARF1 proteins increased with a half-time of 7-8 h, as determined by immunoblot analysis. Induction of mutant ARF1, but not wild-type ARF1, led to an inhibition of protein secretion with kinetics similar to that observed for induction of protein expression. Examination of the Golgi apparatus and the ER by indirect immunofluorescence or transmission electron microscopy revealed that expression of low levels of mutant ARF1 protein correlated with a dramatic increase in vesiculation of the Golgi apparatus and expansion of the ER lumen, while expression of substantially higher levels of wild-type ARF1 had no discernible effect. Endocytosis was also inhibited by expression of mutant ARF1, but not by the wild-type protein. Finally, the expression of [Q71L]ARF1, but not wild-type ARF1, antagonized the actions of brefeldin A, as determined by the delayed loss of ARF and beta-COP from Golgi membranes and disruption of the Golgi apparatus. General models for the actions of ARF1 in membrane traffic events are discussed.
Ferrocenyl fulleropyrrolidines: a cyclic voltammetry study (1994)

The cyclic voltammetry of some fullerene–ferrocene derivatives shows that these compounds possess very interesting electrochemical properties.
Characterization of a spleen sulphotransferase responsible for the 6-O-sulphation of the galactose residue in sialyl-N-acetyl-lactosamine sequences (1998)

An enzyme which catalyses the transfer of sulphate from 3'-phosphoadenosine 5'-phosphosulphate (PAPS) to C-6 of galactose in the NeuAcalpha2-3Galbeta1-4GlcNAc (3'SLN) sequence has been found in rat spleen microsomes and its specificity indicates that it is well suited to participate in the assembly of 3'-sialyl-6'-sulpho-LacNAc [NeuAcalpha2-3Gal(6-SO4)beta1-4GlcNAc] and 3'-sialyl-6'-sulpho-LewisX [NeuAcalpha2-3Gal(6-SO4)beta1-4(Fucalpha1-3)GlcNAc] saccharide groups which have been implicated as selectin ligands. This sulphotransferase has a strict requirement for oligosaccharide acceptors which are capped by an alpha2-3-linked sialic acid residue, although GlcNAc in 3'SLN can be substituted by Glc, and Galbeta1-4GlcNAc can be replaced by Galbeta1-3GlcNAc without loss of activity. The finding that 3'-sialyl LewisX was inert as an acceptor suggested that fucosylation, in contrast with sialylation, follows the addition of the sulphate group. Since fetuin glycopeptides containing the NeuAcalpha2-3Galbeta1-4GlcNAc sequence had a similar affinity for the enzyme as the unattached 3'SLN, it would appear that the acceptor determinants reside primarily in the peripheral trisaccharide constellation. The position of the sulphate on C-6 of galactose was elucidated by Smith periodate oxidation, hydrazine/nitrous acid/NaBH4 treatment and elder (Sambucus nigra) bark lectin chromatography of the desialylated [35S]sulphate-labelled products of the enzyme. Assays carried out with 3'SLN as acceptor indicated that the sulphotransferase had a pH optimum between 6.5 and 7.0 and a dependence on a bivalent cation best met by Mn2+ (12-25 mM); Triton X-100 (0.02 to 0.35%) brought about maximal stimulation. Tentative Km values determined for this enzyme were 4.7 microM for PAPS, and 0.72 mM and 1.16 mM for 3'SLN and fetuin glycopeptides respectively. A survey of several rat organs indicated that the PAPS:3'SLN-6-O-sulphotransferase is selectively distributed with maximal activity occurring in spleen which was substantially greater than thymus or lymph nodes. In contrast, other enzymes (i.e. PAPS:Gal-3-O-and GlcNAc-6-O-sulphotransferases) involved in the sulphation of sialyl-lactosamine and lactosamine sequences, which in the sulphated form are believed to also be selectin ligands, were more evenly distributed in lymphoid tissues. Relatively high activities for all three enzymes were found in brain.
The long-term efficacy and safety of new biological therapies for psoriasis (2006)

Long-term therapy is often required for psoriasis. This article reviews the most recent long-term clinical data for biological agents that have been approved or for which late-stage development data have been released for the treatment of patients with moderate to severe plaque psoriasis. Efficacy data are available for up to five 12-week courses of alefacept (approximately 60 weeks of therapy), 36 months (144 weeks) of continuous efalizumab, 48 weeks of continuous etanercept, and 50 weeks of bimonthly infliximab. Data sources include publications, product labeling, and posters presented at recent international scientific meetings. Alefacept appears to continue to be efficacious over multiple treatment courses for some responsive patients. The efficacy of efalizumab achieved during the first 12-24 weeks of therapy appears to be maintained or improved through at least 60 weeks of continuous treatment. The efficacy of etanercept appears to be maintained through at least 48 weeks of continuous treatment. Infliximab demonstrates a high response rate soon after initiation, which appears to be maintained through 24 weeks but declines modestly with therapy out to 50 weeks. After 48 weeks, approximately 60% of efalizumab-treated and 45% of etanercept-treated patients remaining on therapy achieved > or =75% improvement from baseline in Psoriasis Area and Severity Index, as did 70.5% of infliximab patients who did not miss more than two infusions. Safety data suggest that these agents may be used for long-term administration. Long-term data from psoriasis trials continue to accumulate. Recent data suggest that biological therapies have efficacy and safety profiles suitable for the long-term treatment of patients with moderate to severe psoriasis.
