Alpha‐fetoprotein antagonizes X‐linked inhibitor of apoptosis protein anticaspase activity and disrupts XIAP–caspase interaction (2006)

Previous results have shown that the human oncoembryonic protein alpha-fetoprotein (AFP) induces dose-dependent targeting apoptosis in tumor cells, accompanied by cytochrome c release and caspase 3 activation. AFP positively regulates cytochrome c/dATP-mediated apoptosome complex formation in a cell-free system, stimulates release of the active caspases 9 and 3 and displaces cIAP-2 from the apoptosome and from its complex with recombinant caspases 3 and 9 [Semenkova et al. (2003) Eur. J. Biochem. 270, 276-282]. We suggested that AFP might affect the X-linked inhibitor of apoptosis protein (XIAP)-caspase interaction by blocking binding and activating the apoptotic machinery via abrogation of inhibitory signaling. We show here that AFP cancels XIAP-mediated inhibition of endogenous active caspases in cytosolic lysates of tumor cells, as well as XIAP-induced blockage of active recombinant caspase 3 in a reconstituted cell-free system. A direct protein-protein interaction assay showed that AFP physically interacts with XIAP molecule, abolishes XIAP-caspase binding and rescues caspase 3 from inhibition. The data suggest that AFP is directly involved in targeting positive regulation of the apoptotic pathway dysfunction in cancer cells inhibiting the apoptosis protein function inhibitor, leading to triggering of apoptosis machinery.
Poling effect on the piezoelectric properties of lead zirconate titanate thin films (2002)

The effect of poling on the piezoelectric properties of sol-gel derived PbZr/sub 0.45/Ti/sub 0.55/O/sub 3/ (PZT) thin films is investigated by laser interferometry. Poling conditions are varied in order to optimize the longitudinal piezoelectric coefficient (d/sub 33/) of the films. Short-term aging of d/sub 33/ is also studied to predict the piezoelectric behavior as a function of time. The aging rate and d/sub 33/ values are found to saturate when sufficiently high electric field (/spl sim/200 kV/cm) is applied at room temperature. Further improvement of the piezoelectric properties is achieved with the increase of poling temperature (up to 150/spl deg/C). The poling effect at high temperature is found to correlate with the built-up of an internal bias field, which is responsible for the stabilization of the domain structure. Photoinduced poling using illumination with ultraviolet (UV) light is shown to be an alternative way to improve the piezoelectric properties of films poled at room temperature. The mechanism of the poling effect in PZT thin films is discussed.

Optical anisotropy and liquid‐crystal alignment properties of rubbed polyimide layers (2007)

The relation between the optical anisotropy of rubbed polyimide layers and the rubbing process is investigated using the recently developed polarization‐conversion guided mode technique. Results indicate that the effective optical anisotropy of the polyimide layers may be substantially changed by the rubbing process, although this does not significantly influence the ability of the polyimide layers to align liquid crystals.
A plasmid of Rhizobium meliloti 41 encodes catabolism of two compounds from root exudate of Calystegium sepium (1988)

Our objectives were to identify substances produced by plant roots that might act as nutritional mediators of specific plant-bacterium relationships and to delineate the bacterial genes responsible for catabolizing these substances. We discovered new compounds, which we call calystegins, that have the characteristics of nutritional mediators. They were detected in only 3 of 105 species of higher plants examined: Calystegia sepium, Convolvulus arvensis (both of the Convolvulaceae family), and Atropa belladonna. Calystegins are abundant in organs in contact with the rhizosphere and are not found, or are observed only in small quantities, in aerial plant parts. Just as the synthesis of calystegins is infrequent in the plant kingdom, their catabolism is rare among rhizosphere bacteria that associate with plants and influence their growth. Of 42 such bacteria tested, only one (Rhizobium meliloti 41) was able to catabolize calystegins and use them as a sole source of carbon and nitrogen. The calystegin catabolism gene(s) (cac) in this strain is located on a self-transmissible plasmid (pRme41a), which is not essential to nitrogen-fixing symbiosis with legumes. We suggest that under natural conditions calystegins provide an exclusive carbon and nitrogen source to rhizosphere bacteria which are able to catabolize these compounds. Calystegins (and the corresponding microbial catabolic genes) might be used to analyze and possibly modify rhizosphere ecology.
Surgical Results of Lumbar Interbody Fusion Using Calcium Phosphate Cement (2014)

Clinical and radiological outcomes of lumbar interbody fusion using artificial fusion cages filled with calcium phosphate cements (CPCs) were retrospectively reviewed. Between 2002 and 2011, 25 patients underwent lumbar interbody fusion at Tokushima University Hospital, and 22 patients were enrolled in this study. Of these, 5 patients received autologous local bone grafts and 17 received CPC. Japan Orthopedic Association (JOA) score was used for clinical outcome assessments. Lumbar radiography and computed tomography (CT) were performed at 12, 24 months and last follow-up period to assess bony fusion. The mean JOA score of all patients improved from 9.3 before surgery to 21.0 at 24 months after surgery. Fusion had occurred in 5 of 5 patients in the local bone graft group and in 16 of 17 patients in CPC group at 24 months postoperatively. No surgically related complication was occurred in both groups. CPC is a useful and safe graft material for lumbar interbody fusion.
A generic asset management framework for optimising maintenance investment decision (2008)

This paper proposes a generic asset management framework that integrates enterprise decisions for optimising maintenance investment decisions. Optimisation involves finding the best results for an objective with given restraints and relationships. Three business decision dimensions are used–the annualised costs to the enterprise related to maintenance–namely loss of output cost, resources cost and risk cost. The objective is to reduce costs including those due to risks to the minimum. This paper addresses the relationship between these business decision dimensions within the proposed framework and implements the value per unit time approach for optimisation to occur in an integrated fashion.
Plasma deposited CF polymer films as ultra low k intermetal dielectric, film properties and application (2002)

The ongoing process of miniaturization in ULSI device fabrication has reached its limit. The reduction of cross talk and signal delay time of interconnects requires the application of low permittivity (low k: k <3.9, ultra low k: k<2.2) dielectrics in sub 0.18 /spl mu/m technologies. New materials (low k dielectrics with k/spl les/2.7 in combination with copper) must replace the usually applied SiO/sub 2/ (k/spl ap/3.9) dielectric. Among all new low k materials, amorphous carbon fluoride (CF) polymers deposited by plasma enhanced chemical vapor deposition (PE CVD) are one of the more promising CVD materials with stable 2.3 k. CF polymer films were deposited on silicon and different barrier and etch stop layers. Adhesion failures could be avoided by in situ deposition of a very thin (10 nm) adhesion layer. The influence of the additional film on dielectric film properties (dielectric constant: 2.0/spl les/k/spl les/2.3, break down field strength: Ebd>5 MV/cm, leakage current density @ /spl plusmn/5 V: <4/spl times/10-11 A/cm2) is negligible. After thermal treatment (T/spl les/400/spl deg/C) in vacuum or in nitrogen atmosphere hardly any changes in electrical and optical properties and in surface topology could be detected. Patterning by chemical mechanical polishing (CMP) and reactive ion etching (RIE) was tested successfully and will be applied in single damascene architecture.
Studies on Bacterial Protease (1966)

A crystalline alkaline protease was prepared from B. amylosacchariticus, which was isolated as a strain of saccharogenic α-amylase-producing Bacillus subtilis. The enzyme was most active at pH values between 10.3 and 10.7 towards casein and was stable at pH values from 6 to 11 on twenty hour incubation at 30°C. Calcium ions were effective to stabilize the enzyme especially at higher temperatures. The enzyme was markedly inactivated by DFP as well as protease inhibitor from potato and slightly by surface active agents, but not affected by sulfhydryl reagents and divalent metal ions except Hg++ .Hemoglobin was the best substrate for the enzyme and more than 20% of the peptide bonds were hydrolyzed. Of numerous synthetic peptides tested, only the two compounds, and , were found to be hydrolyzed. A cyclic peptide, gramicidin S, was split by the enzyme only at the peptide bond of -l-valyl-l-ornithyl-. Methyl n-butyrate and tributyrin were also good substrates for the alkaline protease obtained here.
PROPERTIES OF HUMAN PLASMIN (1962)

Several aspects of the properties and preparation of human plasmin are considered. It appears that glycerol activation of the proenzyme is a peculiar property dependent in part on the structure of the glycerol molecule since closely related compounds are without effect. Observations on the influence of ionic strength, on ion activation and inhibition of the enzyme, on substrate specificities, and on preparative procedures are recorded and comparisons with similar data on related bovine enzymes are made.
Identification of mononuclear cells in human blood. II. Evaluation of morphological and immunological aspects of native and formaldehyde-fixed cell populations. (1980)

The presence of surface-associated immunoglobulins and Fc receptors on mononuclear cells from normal human blood was investigated by the direct immunofluorescence technique combined with phase-contrast microscopy. Formaldehyde-fixed cells were compared to unfixed cells and to cells preincubated at 37 degrees C. In the unfixed samples a separate population which showed Fc receptors in an immunofluorescence technique using a labelled antigen--antibody complex was detected. This cell population showed an atypical, i.e. not clearly membrane-associated, pattern of fluorescence with anti-Fab conjugates. This interaction most probably is due to autologous IgG molecules taken up by these cells from the donor serum. Using phase-contrast microscopy, these cells were morphologically distinct from lymphocytes and mature monocytes. They will be referred to as 'undefined mononuclear cells' (UMC). After formaldehyde fixation or preincubation at 37 degrees C the interaction of the UMC with anti-Fab conjugates could no longer be demonstrated. Mature monocytes show the same atypical fluorescence pattern with anti-Fab conjugates, but in contrast to the UMC the interaction persists after formaldehyde fixation or preincubation at 37 degrees C. No evidence was found for passive uptake of labelled IgG from conjugates by any mononuclear cell F(ab')2 fragments of IgG from antisera gave results similar to those obtained with intact IgG fractions. The morphology of the different cell subpopulations is described and their relative numbers in normal blood are given. Formaldehyde fixation proved to be a simple and useful procedure, especially for the determination of the number of B lymphocytes, because the Fc receptor of the undefined mononuclear cell does not give rise to confusion.
A personal authentication scheme using mobile technology (2004)

Security is a major concern in mobile commerce where information is sent over the air. Authentication is possibly the most important property since achieving privacy and integrity may have no sense without the guaranty of the receiver identity. We propose a mobile architecture for strong personal authentication using mobile devices (cellular phones or PDAs) and wireless personal area networks (WPAN) like Bluetooth. The mobile device stores private information and performs cryptographic operations while WPAN connects mobile devices with access points. The risk of insecure wireless networks inclusion is studied and solved using suitable authentication protocols.
Network-Coding Approach for Information-Centric Networking (2018)

The current internet architecture is inefficient in fulfilling the demands of newly emerging internet applications. To address this issue, several over-the-top application-level solutions have been employed, making the overall architecture very complex. Information-centric-networking (ICN) architecture has emerged as a promising alternative solution. The ICN architecture decouples the content from the host at the network level and supports the temporary storage of content in an in-network cache. Fundamentally, the ICN can be considered a multisource, multicast content-delivery solution. Because of the benefits of network coding in multicasting scenarios and proven benefits in distributed storage networks, the network coding is apt for the ICN architecture. In this study, we propose a solvable linear network-coding scheme for the ICN architecture. We also propose a practical implementation of the network-coding scheme for the ICN, particularly for the content-centric network (CCN) architecture, which is termed the coded CCN. The performance results show that the network-coding scheme improves the performance of the CCN and significantly reduces the network traffic and average download delay.
Liver transplantation and non-alcoholic fatty liver disease (2014)

Non-alcoholic fatty liver disease (NAFLD) is an important health problem worldwide. NAFLD encompasses a histological spectrum ranging from bland liver steatosis to severe steatohepatitis (nonalcoholic steatohepatitis, NASH) with the potential of progressing to cirrhosis and its associated morbidity and mortality. NAFLD is thought to be the hepatic manifestation of insulin resistance (or the metabolic syndrome); its prevalence is increasing worldwide in parallel with the obesity epidemic. In many developed countries, NAFLD is the most common cause of liver disease and NASH related cirrhosis is currently the third most common indication for liver transplantation. NASH related cirrhosis is anticipated to become the leading indication for liver transplantation within the next one or two decades. In this review, we discuss how liver transplantation is affected by NAFLD, specifically the following: (1) the increasing need for liver transplantation due to NASH; (2) the impact of the increasing prevalence of NAFLD in the general population on the quality of deceased and live donor livers available for transplantation; (3) the long term graft and patient outcomes after liver transplantation for NASH, and finally; and (4) the de novo occurrence of NAFLD/NASH after liver transplantation and its impact on graft and patient outcomes.
Recombinant antigen-based enzyme immunoassay for screening of Treponema pallidum antibodies in blood bank routine (1995)

This work reports a comparison of an enzyme immunoassay (EIA) using two major Treponema pallidum recombinant antigens with a T. pallidum hemagglutination (TPHA) assay and a nontreponemal Venereal Disease Reference Laboratory (VDRL) test. A total of 1,822 normal donor serum samples was tested for cardiolipin and T. pallidum antibodies, respectively, by the VDRL assay and EIA. Among these samples, 440 were further tested by TPHA technology. Four samples were found positive by EIA, while all were reported to be negative by both TPHA and VDRL routine assays. Subsequent testing of EIA-positive samples confirmed 100% (four of four samples) and 25% (one of four samples) positive results, respectively, by immunofluorescence assay and a Western blot (immunoblot) syphilis kit. The sensitivity of the recombinant EIA was estimated at virtually 100% with a reference panel of 50 syphilitic samples. According to this study, the newly developed EIA kit shows 100% sensitivity combined to a specificity greater than 99.8% for detecting treponemal immunoglobulin G antibodies in blood bank syphilis screening.

Temperature-Induced Intracellular Uptake of Thermoresponsive Polymeric Micelles (2009)

Well-defined diblock copolymers comprising thermoresponsive segments of poly(N-isopropylacrylamide-co-N,N-dimethylacrylamide) (P(IPAAm-co-DMAAm)) and hydrophobic segments of poly(d,l-lactide) were synthesized by combination of RAFT and ring-opening polymerization methods. Terminal conversion of thermoresponsive segments was achieved through reactions of maleimide or its Oregon Green 488 (OG) derivative with thiol groups exposed by cleavage of polymer terminal dithiobenzoate groups. Thermoresponsive micelles obtained from these polymers were approximately 25 nm when below the lower critical solution temperature (LCST) of 40 degrees C, and their sizes increased to an average of approximately 600 nm above the LCST due to aggregation of the micelles. Interestingly, the OG-labeled thermoresponsive micelles showed thermally regulated internalization to cultured endothelial cells, unlike linear thermoresponsive P(IPAAm-co-DMAAm) chains. While intracellular uptake of P(IPAAm-co-DMAAm) was extremely low at temperatures both below and above the micellar LCST, the thermoresponsive micelles showed time-dependent intracellular uptake above the LCST without exhibiting cytotoxicity. These results indicate that the new thermoresponsive micelle system may be a greatly promising intracellular drug delivery tool.

Hybrid Power Quality Compensator With Minimum DC Operation Voltage Design for High-Speed Traction Power Systems (2012)

A hybrid power quality compensator (HPQC) is proposed in this paper for comprehensive compensation under minimum dc operation voltage in high-speed traction power supplies. Reduction in HPQC operation voltage can lead to a decrease in the compensation device capacity, power consumptions, and installation cost. The parameter design procedures for minimum dc voltage operation of HPQC are being explored. It is shown through simulation results that similar compensation performances can be provided by the proposed HPQC with reduced dc-link voltage level compared to the conventional railway power compensator. The system rating can thus be reduced. It is also verified that HPQC would operate at the minimum dc voltage with the proposed parameter design via simulations. A hardware prototype is constructed and the experimental results show that through the proposed design, HPQC is able to provide system unbalance, reactive power, and harmonic compensation in cophase traction power with reduced operation voltage. The cophase traction power supply with proposed HPQC is suitable for high-speed traction applications.
Laser-Beam Zooming to Mitigate Crossed-Beam Energy Losses in Direct-Drive Implosions (2013)

Spherically symmetric direct-drive-ignition designs driven by laser beams with a focal-spot size nearly equal to the target diameter suffer from energy losses due to crossed-beam energy transfer (CBET). Significant reduction of CBET and improvements in implosion hydrodynamic efficiency can be achieved by reducing the beam diameter. Narrow beams increase low-mode perturbations of the targets because of decreased illumination uniformity that degrades implosion performance. Initiating an implosion with nominal beams (equal in size to the target diameter) and reducing the beam diameter by ∼ 30%-40% after developing a sufficiently thick target corona, which smooths the perturbations, mitigate CBET while maintaining low-mode target uniformity in ignition designs with a fusion gain ≫ 1.
Thermal conduction in nanoporous copper inverse opal films (2014)

Copper inverse opal films offer an attractive combination of conduction and convection transport properties that yield a low total thermal resistance for microfluidic heat exchanger applications. In this work, we present an integrated synthesis and characterization strategy to fabricate nanoporous copper inverse opal films and to measure the effective thermal conductivity. We synthesize inverse opal films with sub-micron pore diameters using a sacrificial packed multilayer nanosphere bed to mold the geometry of an electrodeposited copper film. We characterize the effective thermal conductivity using the 3ω method, where the nanoporous copper film is deposited directly above a microfabricated and electrically-passivated 3ω device. The effective thermal conductivity is measured to be as large as 170 W m <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> K <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-1</sup> . This experimental data is compared to finite element simulations as well as common conduction models for heterogeneous media, including Maxwell's model and differential effective medium theory. This provides insight into the design of nanoengineered surfaces and two-phase vapor-venting microfluidic heat exchangers for ultrahigh heat flux cooling.
