Modification of 4-META/MMA-TBB Resin for Safe Debonding of Orthodontic Brackets-Influence of the Addition of Degradable Additives or Fluoride Compound (2006)

The purpose of this study was to evaluate the performance of modified 4-META/MMA-TBB resin cements (Superbond C&B) in terms of debonding orthodontic brackets easily and safely from enamel without the loss of proper bracket bond strength. Poly (DL-lactide-co-glycolide) (PLGA), calcium fluoride (CaF2), or alpha-tricalcium phosphate (alpha-TCP) was added to the polymer powder of 4-META/MMA-TBB resin, and the shear bond strength of orthodontic brackets to human enamel using modified resins was measured before and after 10,000-cycle thermal cycling test between 5 degrees C and 55 degrees C. The modified resins tended to provide lower bond strength compared with the original 4-META/MMA-TBB resin. However, alpha-TCP- or CaF2-modified resin showed no significant differences in bond strength before and after thermal cycling. Moreover, there was a tendency of more residual resin remaining on the tooth surface after debonding, thereby suggesting a lower risk of enamel fracture. In conclusion, alpha-TCP- or CaF2-modified 4-META/MMA-TBB resin seemed to allow easy and safe debonding of orthodontic brackets without loss of proper bracket bond strength.
Histologic Comparison of Autologous Fat Processing Methods (2006)

Of the various processing techniques currently used during autologous fat transfer, sedimentation appears to yield a higher proportion of viable adipocytes than does washing or centrifuging.
Measurement of time-spatial characteristics between indoor spaces in different LOS buildings (2015)

In order to overcome the increasing traffic problems of mobile terminals used in high-rise offices of buildings, it is necessary to clarify the time-spatial characteristics which are composed of the characteristics of the path loss, the delay profile and the spatial arrival angular profile for travelling waves from one high-rise office to another office in a different building. In this paper, we measure the time-spatial characteristics of radio waves passing from one indoor space to another and identify the key parameters determining the time-spatial characteristics based on measured results.
The gene associated with trichorhinophalangeal syndrome in humans is overexpressed in breast cancer (2005)

A comprehensive differential gene expression screen on a panel of 54 breast tumors and >200 normal tissue samples using DNA microarrays revealed 15 genes specifically overexpressed in breast cancer. One of the most prevalent genes found was trichorhinophalangeal syndrome type 1 (TRPS-1), a gene previously shown to be associated with three rare autosomal dominant genetic disorders known as the trichorhinophalangeal syndromes. A number of corroborating methodologies, including in situ hybridization, e-Northern analysis using ORF EST (ORESTES) and Unigene EST abundance analysis, immunoblot and immunofluorescence analysis of breast tumor cell lines, and immunohistochemistry, confirmed the microarray findings. Immunohistochemistry analysis found TRPS-1 protein expressed in >90% of early- and late-stage breast cancer, including ductal carcinoma in situ and invasive ductal, lobular, and papillary carcinomas. The TRPS-1 gene is also immunogenic with processed and presented peptides activating T cells found after vaccination of HLA-A2.1 transgenic mouse. Human T cell lines from HLA-A*0201+ female donors exhibiting TRPS-1-specific cytotoxic T lymphocyte activity could also be generated.
Inaccuracies in measurement of contact pressure due to the measuring grid of a foil sensor (2007)

The measurement of contact stresses between elastic bodies is of great importance in a wide range of fields. Many methods are based on a sensor sheet which is placed between the bodies in contact. Depending on the application, the accuracy of measuring results can be considerably affected by the finite thickness and structure of the inserted sensor. This study deals with the imprecision of the Tekscan system and attempts to explain the cause of deviations. For this purpose an imprint method using Fuji prescale film/GODAV software and the Finite Element (FE) method was used to compare the results with those results of the Tekscan system. As an example where high inaccuracies can be caused by the measuring grid of the Tekscan sensor, the pressure distribution in the contact area between the rope and the polyamide inlay of a pulley wheel was measured. The results demonstrate clearly the high influence of the sensor grid.
Repeated-batch production of galactooligosaccharides from lactose at high concentration by using alginate-immobilized cells of Sporobolomyces singularis YIT 10047 (2008)

We investigated the production of galactooligosaccharides (GOS) from lactose by alginate-immobilized cells of Sporobolomyces singularis YIT 10047 (IM-SS). beta-Galactosidase activity was stable at 30 to 50 degrees C but decreased dramatically between 50 and 60 degrees C and disappeared at 70 degrees C in acetate buffer. The enzyme activity remaining was no more than 20% of that of unheated samples after incubation in distilled water at 55 degrees C, whereas its value was about 60% at the same temperature under buffered condition. However, activity was maintained more than 80% with 10% to 50% (w/w) lactose after incubation at 55 degrees C without buffer. In a single-batch reaction, GOS yield was 41.0% with free cells and 40.4% with IM-SS. We attempted a repeated-batch reaction using IM-SS with 600 g L(-1)lactose. IM-SS produced GOS stably for 20 batches (22 h/batch, 440 h in total) at 55 degrees C and pH 5.0 or 6.0. IM-SS produced GOS at 242 g L(-1), at a rate of 8.72 g L(-1) h(-1). Both GOS yield and production rate were higher than those in published experiments on GOS production using immobilized biocatalysts. The repeated-batch reaction with IM-SS would be an ideal system for GOS production because of its stability and high productivity.
The parallel implementation of the waveform relaxation method for transient stability simulations (1990)

The WR (waveform relaxation) algorithm is extended to a structure-preserving power system model in which the loads are retained. This results in a system of differential/algebraic equations (DAEs). Power system exhibit several unique dynamic properties which may be exploited in an advantageous manner by the WR algorithm. These physical properties include the coherency properties of the power system which lead to the partitions for the textured model approach, the near diagonal dominance which leads to longer windows for uniform convergence, and the localized response from which the multirate capabilities of the WR method can be used. These characteristics enable power systems to obtain more favorable results than were obtained in VLSI simulations. The authors present several theoretical results as well as computational results on parallel implementation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Bilateral texture filtering (2014)

This paper presents a novel structure-preserving image decomposition operator called bilateral texture filter . As a simple modification of the original bilateral filter [Tomasi and Manduchi 1998], it performs local patch-based analysis of texture features and incorporates its results into the range filter kernel. The central idea to ensure proper texture/structure separation is based on patch shift that captures the texture information from the most representative texture patch clear of prominent structure edges. Our method outperforms the original bilateral filter in removing texture while preserving main image structures, at the cost of some added computation. It inherits well-known advantages of the bilateral filter, such as simplicity, local nature, ease of implementation, scalability, and adaptability to other application scenarios.
Identity of Tarichatoxin and Tetrodotoxin (1964)

Tarichatoxin (C(11)H(17)N(3)O(8)), a potent neurotoxin recently isolated in pure form from the eggs of the California newt, Taricha torosa, has been found to be identical to tetrodotoxin from the ovaries of Sphoeroides rubripes, the Japanese Fugu or puffer fish. As yet this substance has been detected only in a single family of fish, Tetraodontidae, and in a single family of amphibia, Salamandridae.
<title>Micromachined flow-handling components: micropumps</title> (1999)

Microfluidic components, especially micropumps, are essential for miniaturized dosing systems, Micro Total Analysis Systems and miniaturized labs for medical diagnosis. A variety of micropumps for these different applications have been developed at the Institut fuer Mikrotechnik Mainz GmbH.
SCALE DEPOSITS IN POROUS MEDIA AND THEIR REMOVAL BY EDTA INJECTION (2007)

Formation damage has been observed in several oil reservoirs and production equipment in Iranian oil fields. Laboratory and field testing confirmed that the primary cause of damage was the build-up of calcium carbonate, calcium sulfate and strontium sulfate scale either in the perforation tunnels or in the formation sandstone nears the wellbore. Conventional acid treatments could dissolve this scale, but scale precipitation from the spent acid caused rapid productivity decline. A scale removal treatment with Na2H2EDTA has been developed that can effectively dissolve scale and chelate the dissolved metal ions. Chelation of the dissolved scale prevents scale reprecipitation. This study describes the results of an experimental and theoretical study on the removal of formation damage resulting from scale formation in porous media. An experimental investigation was undertaken to look into the possible causes of the injectivity loss in a typical Iranian oilfield. Sets of experimental investigations were undertaken with different objectives in mind. Glass and sand bead packs were used to test the experimental set up and to observe the general behaviour of scale formation and removal by ethylene diamine tetra acetic acid (EDTA) to determine its possible effects on the permeability of the porous medium.
The highly conserved Ndc80 complex is required for kinetochore assembly, chromosome congression, and spindle checkpoint activity (2003)

We show that the Xenopus homologs of Ndc80/Tid3/HEC1 (xNdc80) and Nuf2/MPP1/Him-10 (xNuf2) proteins physically interact in a 190-kD complex that associates with the outer kinetochore from prometaphase through anaphase. Injecting function-blocking antibodies to either xNdc80 or xNuf2 into XTC cells caused premature exit from mitosis without detectable chromosome congression or anaphase movements. Injected cells did not arrest in response to microtubule drugs, showing that the complex is required for the spindle checkpoint. Kinetochores assembled in Xenopus extracts after immunodepletion of the complex did not contain xRod, xZw10, xP150 glued (Dynactin), xMad1, xMad2, xBub1, and xBub3, demonstrating that the xNdc80 complex is required for functional kinetochore assembly. In contrast, function-blocking antibodies did not affect the localization of other kinetochore proteins when added to extracts containing previously assembled kinetochores. These extracts with intact kinetochores were deficient in checkpoint signaling, suggesting that the Ndc80 complex participates in the spindle checkpoint. We also demonstrate that the spindle checkpoint can arrest budding yeast cells lacking Ndc80 or Nuf2, whereas yeast lacking both proteins fail to arrest in mitosis. Systematic deletion of yeast kinetochore genes suggests that the Ndc80 complex has a unique role in spindle checkpoint signaling. We propose that the Ndc80 complex has conserved roles in kinetochore assembly, chromosome congression, and spindle checkpoint signaling.
Treatment of Fuel-Oil Contaminated Soils by Biodegradable Surfactant Washing Followed by Fenton-Like Oxidation (2009)

Among petroleum-hydrocarbon pollutants, fuel-oil is more difficult to treat compared to gasoline and diesel fuel. The objectives of this bench-scale study were to: (1) develop a two-stage remedial system consisting of surfactant washing followed by Fenton-like oxidation process to remediate fuel-oil contaminated soils; (2) evaluate the effects of residual surfactant and soil organic matter (SOM) on the efficiency of Fenton-like oxidation; (3) evaluate the effect of potassium dihydrogen phosphate (KH2PO4) addition on the stability of H2O2 and oxidation efficiency; and (4) evaluate the possible oxidation products after the oxidation process. In the surfactant washing stage, biodegradable surfactant, Simple Green (SG) (50 g L−1) , was applied to flush fuel-oil contaminated soils with initial total petroleum-hydrocarbons (TPHs) concentration of 50,000 mg kg−1 . Results show that approximately 90% of TPH could be removed after washing with 45 pore volumes (PVs) of SG followed by 25 PVs of deionized water, while the soil TPH concentration dropped from 50,000 to 4,950 mg kg−1 . In the Fenton-like oxidation stage with initial soil TPH concentration was approximately 4,950 mg kg−1 , TPH removal efficiency can be significantly increased with increased H2O2 concentrations. Results also reveal that residual SG and SOM would compete with TPH for oxidants and cause the decrease in oxidation efficiency. An “oxidation-sorption-desorption-oxidation” scheme for soil TPH was observed in this experiment due to the initial sorption of TPH on SOM. Results show that an addition of 2.2 mM of KH2PO4 could increase the stability and half-life of H2O2 , but caused the decrease in TPH removal efficiency. The oxidation potential of Fenton-like process was not capable of completely oxidizing fuel-oil to nontoxic end products. The observed by-products after oxidation process contained carboxyl groups with molecular weights similar to their parent compounds. Results from this study indicate that the two-stage remedial system is a promising technology for fuel-oil contaminated soil treatment.
Complete amino acid sequence of mouse prolactin (1984)

The complete primary structure of mouse prolactin has been established on the basis of tryptic peptides from cyanogen-bromide-treated, S-carboxymethylated mouse prolactin and Staphylococcus-aureus-protease-cleaved overlaps, which were sequenced by manual liquid-phase and solid-phase Edman degradation. Three disulfide bonds were assigned to Cys-4-Cys-9, Cys-56-Cys-172, and Cys-189-Cys-197 by digestion of intact prolactin with S. aureus protease. One of the characteristics to date is replacement of Trp-89, which is commonly present among prolactin, growth hormone and choriomammotropin, by serine. It was suggested, by comparison with five other prolactins, five growth hormones and human choriomammotropin, that Asp-18, His-25, Ser-60 and Thr-63 are essential to lactogenic activity.
Cardiac pacing in heart failure patients with left bundle branch block: impact of pacing site for optimizing left ventricular resynchronization. (2000)

In heart failure patients with left bundle branch block, dual-site pacing improves systolic function more than single-site stimulation. Improved ventricular activation synchrony, expressed by paced QRS narrowing, may account for the additional benefit of dual- vs single-site pacing in enhancing contractility. This novel approach deserves consideration for future heart failure pacing studies.

Effects of additive elements on improvement of the dielectric properties of Ta2O5 films formed by metalorganic decomposition (2003)

Ta 2 O 5 -based composite thin films formed by metalorganic decomposition have been investigated with respect to their dielectric properties. The dielectric and insulating properties of composite (1−x)Ta2O5−xTiO2 and (1−x)Ta2O5−xWO3 thin films are found to be improved compared to those of pure Ta2O5 thin films. In particular, thin films with x=0.08 composition of additive TiO2 or WO3 to Ta2O5 exhibited superior dielectric and insulating properties. The maximum dielectric constant and charge storage density of composite films are about 20 and 53.6 fC/μm2, respectively, higher than those of pure Ta2O5 films (about 13 and 34.5 fC/μm2). The temperature coefficient of the dielectric constant of composite films dramatically decreases from 65 ppm/°C for pure Ta2O5 to less than 11 ppm/°C. The leakage current density of composite films is lower than 1×10−9 A/cm2 up to an applied electric field of 3 MV/cm. The dominant conduction is Poole–Frenkel conduction in the films according to the measurement temperature dependence of the I−V characteristics.
Inactivation of bradykinin by angiotensin-converting enzyme and by carboxypeptidase N in human plasma (2000)

Because bradykinin (BK) appears to have cardioprotective effects ranging from improved hemodynamics to antiproliferative effects, inhibition of BK-degrading enzymes should potentiate such actions. The purpose of this study was to find out which enzymes are responsible for the degradation of BK in human plasma. Human plasma from healthy donors (n = 10) was incubated with BK in the presence or absence of specific enzyme inhibitors. At high (micromolar) concentrations, BK was mostly (>90%) degraded by carboxypeptidase N (CPN)-like activity. In contrast, at low (nanomolar) substrate concentrations, at which the velocity of the catalytic reaction is equivalent to that under physiological conditions, BK was mostly (>90%) converted into an inactive metabolite, BK-(1-7), by angiotensin-converting enzyme (ACE). BK-(1-7) was further converted by ACE into BK-(1-5), with accumulation of this active peptide. A minor fraction (<10%) of the BK was converted into another active metabolite, BK-(1-8), by CPN-like activity. The present study shows that the most critical step in plasma kinin metabolism, i.e., inactivation of BK, is mediated by ACE. Thus inhibition of plasma ACE activity would be cardioprotective by elevating the concentration of BK in the circulation.
Isopentenyl diphosphate isomerase deficiency in <i>Synechocystis</i> sp. strain PCC6803 (2000)

Isopentenyl diphosphate isomerase (IPP isomerase) in many organisms and in plastids is central to isoprenoid synthesis and involves the conversion between IPP and dimethylallyl diphosphate (DMAPP). It is shown that Synechocystis PCC6803 is deficient in IPP isomerase activity, consistent with the absence in its genome of an obvious homologue for the enzyme. Incorporation of [1-(14)C]IPP in cell extracts, primarily into C(20), occurs only upon priming with DMAPP in Synechocystis PCC6803 and in Synechococcus PCC7942. Isoprenoid synthesis in these cyanobacteria does not appear to involve interconversion of IPP and DMAPP, raising the possibility that they are not within the plastid evolutionary lineage.
Fabrication of photonic integrated circuits by DUV-induced modification of polymers (2004)

The expansion of high capacity optical transmission techniques into price-sensitive areas such as datacom and access networks requires a major reduction in the cost of optical components. Polymer waveguides are attractive because they are very simple to process and are promising for low-cost devices. Deep UV-induced modification of the dielectric properties of polymers is a useful technique for low cost realization of integrated optical circuits for telecommunication und sensor applications. The technique presented here has several advantages with respect to common methods because only a single polymer layer is used, which serves as the substrate and waveguide as well and no further etching or development step is required. The integration of the waveguide circuits in a polymer microoptical bench offers the possibility of combining the devices with semiconductor based optical circuits and also achieve easy fiber-chip coupling. In this work, preliminary results of Y-junctions, directional couplers, multimode interference (MMI) couplers will be given.
Knuckle Sandwich and Sore Thumbs (1997)

In 1975 I became involved with a group of community activists who tried to set up an 'alternative' youth and community centre on a large rundown GLC (Greater London Council) estate near King's Cross. The project was largely inspired by the romantic populism of the Libertarian Left' of this period. But if we had hoped to build the New Jerusulem in this most unpromised land, we were quickly disillusioned by the local realpolitik. The derelict pub which we had occupied and converted with the help of a Council grant became a battleground for a whole range of competing interests all claiming to represent 'the community'. Our uncomplicated vision of cultural negotiation was no match for a tactical alliance between local villains who saw the chance of some easy pickings, and conservative elements amongst the council tenantry alarmed at the prospect of their young people being corrupted by long-haired lefties from Liverpool Road. One night, shortly after it had opened, the pub burnt down under mysterious circumstances, and the tenants' association acquired enough insurance money to build the bingo palace they really wanted.
Polarization insensitive wideband tunable dispersion compensator with integrated PLC type polarization diversity circuit (2006)

1.58 µm band Er <sup>3+</sup> -doped fibre amplifierpumped in the 0.98 and 1.48 µm bands (1997)

The amplification characteristics of 1.58 µm band Er3+-doped fibre amplifiers pumped in the 0.98 and 1.48 µm bands were investigated. The noise characteristics were improved by adopting 0.98 µm band pumping. There was > 0.3 dB improvement in both the average noise figure and the flatness of the noise figure.
