Urothelial Tissue Culture for Bladder Reconstruction: An Experimental Study (1993)

An in vitro system for the growth of normal human urothelial cells has been developed. Urothelial cells were isolated from tissue samples in 38 patients and cultured in a defined serum-free medium. Confluent cell monolayers of 25 cm.2 were produced after 7 days in 32 cases. Subsequent subcultures at a 1:20 split ratio achieved confluency within another 7 days and a consistently high rate of growth was sustained for at least 7 passages. Characterization by immunofluorescence with a panel of antibodies demonstrated that the cultured cells were exclusively epithelial and retained the characteristic antigenic profile of normal urothelium, even after extended periods in culture. The only consistent cause of failure (6 of 38 cases) was bacterial contamination secondary to an underlying urinary tract infection in these patients.
Application of thin-film inductors to LC filters (1993)

The application of thin film inductors to thin film based LC filters is discussed. The trial monolithic thin film LC filter consists of thin film inductors and thin film capacitors, fabricated by RF sputtering and ion-milling techniques. This filter is a second-order low pass filter with a cutoff frequency of 50 MHz. Two kinds of filters are fabricated, using a nonmagnetic thin film inductor on a magnetic thin film inductor. It is proved that magnetic thin film permits the reduction of the size and the insertion loss of the filter.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Agglutination of intravenous lipid emulsion ('Intralipid') and plasma lipoproteins by C-reactive protein. (1986)

Isolated human C-reactive protein (CRP), or CRP in acute phase serum, produced in-vitro agglutination ('creaming') of the intravenously administered lipid suspension 'Intralipid'. CRP also produced similar agglutination of isolated normal very low density lipoproteins (VLDL). Agglutination in both cases was calcium-dependent and inhibitable by phosphoryl choline. These findings have important implications for patients receiving intravenous lipid suspensions and may be relevant to the pathogenesis of the fat embolism syndrome following trauma.
MyoD-positive epiblast cells regulate skeletal muscle differentiation in the embryo (2006)

MyoD mRNA is expressed in a subpopulation of cells within the embryonic epiblast. Most of these cells are incorporated into somites and synthesize Noggin. Ablation of MyoD-positive cells in the epiblast subsequently results in the herniation of organs through the ventral body wall, a decrease in the expression of Noggin, MyoD, Myf5, and myosin in the somites and limbs, and an increase in Pax-3-positive myogenic precursors. The addition of Noggin lateral to the somites compensates for the loss of MyoD-positive epiblast cells. Skeletal muscle stem cells that arise in the epiblast are utilized in the somites to promote muscle differentiation by serving as a source of Noggin.
Image‐Based Crack Detection for Real Concrete Surfaces (2007)

Abstract In this paper, we introduce a novel image‐based approach to detect cracks in concrete surfaces. Crack detection is important for the inspection, diagnosis, and maintenance of concrete structures. However, conventional image‐based approaches cannot achieve precise detection since the image of the concrete surface contains various types of noise due to different causes such as concrete blebs, stain, insufficient contrast, and shading. In order to detect the cracks with high fidelity, we assume that they are composed of thin interconnected textures and propose an image‐based percolation model that extracts a continuous texture by referring to the connectivity of brightness and the shape of the percolated region, depending on the length criterion of the scalable local image processing techniques. Additionally, noise reduction based on the percolation model is proposed. We evaluated the validity of the proposed technique by using precision recall and receiver operating characteristic (ROC) analysis by means of some experiments with actual concrete surface images.

Hedge Fund Benchmarks: A Risk-Based Approach (2004)

Following a review of the data and methodological difficulties in applying conventional models used for traditional asset class indexes to hedge funds, this article argues against the conventional approach. Instead, in an extension of previous work on asset-based style (ABS) factors, the article proposes a model of hedge fund returns that is similar to models based on arbitrage pricing theory, with dynamic risk-factor coefficients. For diversified hedge fund portfolios (as proxied by indexes of hedge funds and funds of hedge funds), the seven ABS factors can explain up to 80 percent of monthly return variations. Because ABS factors are directly observable from market prices, this model provides a standardized framework for identifying differences among major hedge fund indexes that is free of the biases inherent in hedge fund databases.
Ticlopidine Selectively Inhibits Human Platelet Responses to Adenosine Diphosphate (1991)

Platelet aggregation and fibrinogen binding were studied in 15 individuals before and 7 days after the oral administration of ticlopidine (250 mg b.i.d.). Ticlopidine significantly inhibited platelet aggregation induced by adenosine diphosphate (ADP), the endoperoxide analogue U46619, collagen or low concentrations of thrombin, but did not inhibit platelet aggregation induced by epinephrine or high concentrations of thrombin. Ticlopidine inhibited 125I-fibrinogen binding induced by ADP, U46619 or thrombin (1 U/ml). The ADP scavengers apyrase or CP/CPK, added in vitro to platelet suspensions obtained before ticlopidine, caused the same pattern of aggregation and 125I-fibrinogen binding inhibition as did ticlopidine. Ticlopidine did not inhibit further platelet aggregation and 125I-fibrinogen binding induced in the presence of ADP scavengers. After ticlopidine administration, thrombin or U46619, but not ADP, increased the binding rate of the anti-GPII b/III a monoclonal antibody 7E3 to platelets. Ticlopidine inhibited clot retraction induced by reptilase plus ADP, but not that induced by thrombin or by reptilase plus epinephrine, and prevented the inhibitory effect of ADP, but not that of epinephrine, on the PGE1-induced increase in platelet cyclic AMP. The number of high- and low-affinity binding sites for 3H-ADP on formalin-fixed platelets and their Kd were not modified by ticlopidine. These findings indicate that ticlopidine selectively inhibits platelet responses to ADP.
Solution-Processable Field-Effect Transistors Fabricated Using Aryl Phenoxazine Based Polymers as the Active Layer (2009)

Three phenoxazine-based conjugated polymers, namely, the aryl substituted phenoxazine homopolymer (P1) as well as the dimeric phenoxazine-fluorene (P2) and phenoxazine-bithiophene (P3) copolymers, were synthesized via the Ni(0) mediated Yamamoto reaction and the palladium-catalyzed Suzuki coupling reaction. The weight-averaged molecular weights (<TEX>$M_w$</TEX>) of P1, P2, and P3 were found to be 27,000, 22,000, and 15,000, respectively, and their polydispersity indices were 3.6, 1.8, and 2.1. All the polymers were soluble in common organic solvents such as chloroform, toluene, and so on. The UV-visible absorption maxima for P1, P2, and P3 in the film state were located at 421, 415 and 426 nm, respectively, and the ionization potentials of the polymers ranged between 4.90 and 5.12 eV. All the studied phenoxazine-based polymers exhibited amorphous behavior, as confirmed by X-ray diffraction (XRD) and atomic force microscopy (AFM) studies. Thin film transistors were fabricated using the top-contact geometry. P1 showed much better thin-film-transistor performance than P2 or P3: A thin film of P1 gave a saturation mobility of 0.81 <TEX>${\times}\;10^{-3}\;cm^2V^{-1}s^{-1}$</TEX> and an on/off ratio of about <TEX>$10^2$</TEX>.
Adaptive Echo Canceller Based on Unbiased Adaptive IIR Notch Filter (2008)

In this paper, an adaptive echo canceller based on unbiased equation error adaptive IIR notch filter for the echo cancellation in telephone network is presented. The unbiased equation error algorithm employs the bias removal techniques to remove the bias existing in the estimated parameter, resulting in obtaining good estimate of parameter for the echo canceller. The computer simulation results in terms of echo return loss enhancement (ERLE) are provided to confirm the performances of the presented adaptive echo canceller.
Aerobic TMAO respiration in <i>Escherichia coli</i> (2007)

In the absence of oxygen, Escherichia coli can use alternative exogenous electron acceptors, including trimethylamine oxide (TMAO), to generate energy. In this study, we showed that in contrast to the other anaerobic respiratory systems, the TMAO reductase (Tor) system was expressed during both aerobiosis and anaerobiosis. By using a torA-lacZ fusion and quantitative reverse transcription polymerase chain reaction, we established that the torCAD operon encoding the Tor system was induced in the presence of TMAO mainly during exponential phase, and that optimal induction required a certain level of DNA supercoiling. We also showed that the presence of oxygen prevented neither the biogenesis of the Tor system nor the reduction of TMAO. The physiological role of TMAO reduction during aerobiosis has not been yet established, but our experiments suggest that alkaline TMA production could enhance the growth conditions by increasing the pH of the culture.
The Impact of Self-Retaining Retractors on the Paraspinal Muscles During Posterior Spinal Surgery (2002)

A substantial rise in pressure in the erector spinae muscle during posterior spinal surgery was observed, and this appeared to be associated with marked changes in the function of the muscles. This could be an important factor in the generation of operative scar tissue and postoperative dysfunction of the spinal muscles.
GeneSigDB—a curated database of gene expression signatures (2009)

The primary objective of most gene expression studies is the identification of one or more gene signatures; lists of genes whose transcriptional levels are uniquely associated with a specific biological phenotype. Whilst thousands of experimentally derived gene signatures are published, their potential value to the community is limited by their computational inaccessibility. Gene signatures are embedded in published article figures, tables or in supplementary materials, and are frequently presented using non-standard gene or probeset nomenclature. We present GeneSigDB (http://compbio.dfci.harvard.edu/genesigdb) a manually curated database of gene expression signatures. GeneSigDB release 1.0 focuses on cancer and stem cells gene signatures and was constructed from more than 850 publications from which we manually transcribed 575 gene signatures. Most gene signatures (n = 560) were successfully mapped to the genome to extract standardized lists of EnsEMBL gene identifiers. GeneSigDB provides the original gene signature, the standardized gene list and a fully traceable gene mapping history for each gene from the original transcribed data table through to the standardized list of genes. The GeneSigDB web portal is easy to search, allows users to compare their own gene list to those in the database, and download gene signatures in most common gene identifier formats.

Interaction of mitochondrial initiation factor 2 with mitochondrial fMet-tRNA (2004)

The mammalian mitochondrial genome contains a single tRNA(Met) gene that gives rise to the initiator and elongator tRNA(Met). It is generally believed that mitochondrial protein synthesis begins with formylmethionyl-tRNA, which indicates that the formylation of mitochondrial Met-tRNA specifies its participation in initiation through its interaction with initiation factor 2 (IF-2). However, recent studies in yeast mitochondria, suggest that formylation is not required for protein synthesis. In addition, bovine IF-2(mt) could replace yeast IF-2(mt) in strains that lack fMet-tRNA which suggests that this paradigm may extend to mammalian mitochondria. Here, the importance of the formylation of mitochondrial Met-tRNA for the interaction with IF-2(mt) was investigated by measuring the ability of bovine IF-2(mt) to bind mitochondrial fMet-tRNA. In direct binding experiments, bovine IF-2(mt) has a 25-fold greater affinity for mitochondrial fMet-tRNA than Met-tRNA, using either the native mitochondrial tRNA(Met) or an in vitro transcript of bovine mitochondrial tRNA(Met). In addition, IF-2(mt) will not effectively stimulate mitochondrial Met-tRNA binding to mitochondrial ribosomes, exhibiting a 50-fold preference for fMet-tRNA over Met-tRNA in this assay. Finally, the region of IF-2(mt) responsible for the interaction with fMet-tRNA was mapped to the C2 sub-domain of domain VI of this factor.
Design of coaxial resonator filter with nonuniform dissipation (2008)

This paper presents a novel design of narrow bandpass filter based on a new filter synthesis technique which allows for the realization of lossy filters with ideal lossless transmission and reflection response, offset by a constant amount. An experimental three-pole Chebyshev filter having 6 dB insertion loss and return loss better than 26 dB in the passband is demonstrated. This new class of filter would be useful in microwave systems where the increased insertion loss can be tolerated, such as in a satellite IMUX.
Optimum Design of Piled Raft Foundations Using the Data-filtering Hybrid Genetic Algorithm (2010)

A new approach using the hybrid genetic-based evolution algorithm without gradient requirements is proposed for the optimum design of piled raft foundations. Objective functions considered are the differential settlement based on a serviceability of the structure and the cost-based total weight of the raft and piles. In formulating the genetic algorithm-based optimum design procedure, the analysis of piled raft foundations is performed based on the hybrid finite element-elastic continuum-load transfer approach developed by Clancy, considering interaction effects between pile-soil-pile, raft-soil-raft, and raft-soil-pile. The simple genetic algorithm by Goldberg is used as a basis for the optimum design of piled raft foundations. In addition, a hybridization of the Goldberg`s simple genetic algorithm is performed by incorporating a data-filtering routine as Lamarckian`s evolution. To verify the validity of the proposed data-filtering hybrid genetic algorithm-based optimum design procedure, the optimized location of piles is compared with results of small-scaled model tests. The load-sharing ratios between piles and the raft are also investigated based on model test results. Further to examine the efficiency of the proposed design procedure, two examples of piled raft foundations are analyzed.
[Survivin: anti-apoptosis protein and a prognostic marker for tumor progression and recurrence]. (2002)

The recently discovered 16.5 kDa protein survivin was found to inhibit the two early apoptotic enzymes caspase-3 and caspase-7, thus preventing programmed cell death. Survivin may act simultaneously with the bel-2 family proteins, but has a different apoptosis inhibitory mechanism. Numerous reports have demonstrated the expression of survivin in various tumors such as neuroblastoma, melanoma, bladder carcinoma, breast and lung non-small cell tumors, esophegeal and colo-rectal carcinomas and leukemic cells. In contrast, this protein was not traced in adjacent normal tissues by either immunohistochemical staining or by PCR analysis of the expression of survivin mRNA. Importantly, there seems to be a positive correlation between survivin expression and tumor grading, as well as an indication of tumor recurrence after resection or chemotherapy. Potentially, this protein could add to the repertory of diagnostic and prognostic markers in monitoring oncologic patients.
환원슬래그를 이용하여 개발된 자기발열 시멘트의 해외 Mock-up Test 관한 연구 (2017)

MOCK-UP TEST was conducted in the extreme region of the cement which was researched and developed by using the reducing slag Experimental results show that the basic properties (air volume, slump) are improved compared with the specimens using Mongolian cement. The compressive strength achieved the target strength (target strength: age 3day: 7MPa, age 7day 14MPa) and the hydration heat was about 8 ℃ higher than that of Mongolian cement products. Therefore, it is considered that the cement powders developed by our company showed the strength of concrete due to high hydration heat even at extreme temperatures.

Multiple hierarchical transmission scheme with bit interleaver over Rayleigh fading channel (2002)

We present multilevel hierarchical coding with diagonal and block interleaving scheme applied in a Rayleigh fading channel in which both the capacity rule and block partitioning have been taken into accord. Simulated by computer, the performance of level 3 is more than 1 dB better than no interleaving at two levels at error probability of 10/sup -5/. This scheme can use in the diagonally layered space-time architecture.
Techniques of field gamma-ray spectrometry (1981)

Abstract Field gamma-ray spectrometry is a rapid and effective quantitative method of mapping variations of radioelements within igneous intrusions. A field procedure for radioelement mapping demonstrates the value of the method to studies of late-stage magmatic processes during the emplacement of granite intrusions and the determination of their present-day heat productivities. Methods and problems of instrument calibration using both natural and artificial sources are discussed. Calibration based on neutron activation analysis of samples from natural outcrops achieves results comparable with those obtained using artificial sources and has the advantage that it relates directly to field conditions; furthermore it enables secular disequilibrium in the uranium and thorium decay series to be recognized.
High-Performance WSe<sub>2</sub>Complementary Metal Oxide Semiconductor Technology and Integrated Circuits (2015)

Because of their extraordinary structural and electrical properties, two-dimensional materials are currently being pursued for applications such as thin-film transistors and integrated circuit. One of the main challenges that still needs to be overcome for these applications is the fabrication of air-stable transistors with industry-compatible complementary metal oxide semiconductor (CMOS) technology. In this work, we experimentally demonstrate a novel high performance air-stable WSe2 CMOS technology with almost ideal voltage transfer characteristic, full logic swing and high noise margin with different supply voltages. More importantly, the inverter shows large voltage gain (∼38) and small static power (picowatts), paving the way for low power electronic system in 2D materials.
Lipid extraction attenuates the calcific degeneration of bovine pericardium used in cardiac valve bioprostheses. (1990)

Bovine pericardial bioprostheses frequently fail due to dystrophic calcification. Since (a) recent studies indicate that membrane-associated complexed acidic phospholipids play an important role in the process of both physiologic and pathologic calcification, and (b) cytoplasmic organelles and plasma membrane of interstitial cells seem to serve as initial sites of calcific degeneration of bioprosthetic bovine pericardial tissue, this investigation was undertaken to evaluate whether, and if so, to what extent, the mineralization of valve tissue could be attenuated by previous lipid extraction. Pretreatment of glutaraldehyde-preserved bovine pericardium with acidified sulphuric ether (pH 3.0-4.0) attenuated calcification significantly: 28 days after subcutaneous implantation in young rats the degree of mineral deposition was approximately equal to typical 7 days implants in this model. The mechanism of this beneficial effect is suggested to be due to partial extraction of tissue phospholipids, as demonstrated by electron microscopy, thus reducing the number of available sites for deposition of hydroxyapatite crystals. In addition, and importantly, the present results indicate that any attempt to reduce cardiac valve bioprosthesis mineralization will have to take into account the role of lipids and, particularly, the membranous phospholipids in the calcification mechanism.
