Cell Adhesion Kinase β Forms a Complex with a New Member, Hic-5, of Proteins Localized at Focal Adhesions (1998)

Cell adhesion kinase beta (CAKbeta/PYK2) is the second protein-tyrosine kinase of the focal adhesion kinase subfamily. We identified a cDNA that encodes a CAKbeta-binding protein. This cDNA clone encodes the human homologue of Hic-5, the cDNA of which was cloned in 1994 as transforming growth factor beta1- and hydrogen peroxide-inducible mRNA. We found that Hic-5 exclusively localized at focal adhesions in a rat fibroblast line, WFB. This localization of Hic-5 was confirmed in WFB cells expressing Myc-tagged Hic-5. The amino acid sequence of Hic-5 is highly similar to that of paxillin in the four LD motifs as well as in the four contiguous LIM domains. The Hic-5 N-terminal domain directly associated in vitro with the extreme C-terminal region (residue 801 to the end) of CAKbeta. CAKbeta was coimmunoprecipitated with Hic-5 from the WFB cell lysate. The coimmunoprecipitation of CAKbeta with Hic-5 was markedly inhibited by the addition of the extreme C-terminal region of CAKbeta. Coimmunoprecipitation of Hic-5 with CAKbeta, which was shown in COS-7 cells doubly transfected with cDNA constructs of CAKbeta and Myc-tagged Hic-5, was lost when the CAKbeta amino acid residues 741-903 were deleted. Hic-5 was tyrosine-phosphorylated in Src-transformed 3Y1 cells and in cells treated with pervanadate. Hic-5 associated with CAKbeta was selectively tyrosine-phosphorylated in WFB cells exposed to hypertonic osmotic stress. These results indicate that Hic-5 is a paxillin-related component of focal adhesions and binds to CAKbeta, implying possible involvement of Hic-5 in the downstream signaling of CAKbeta.

Characterization of the immunocompetent cells of rheumatoid synovium from tissue sections and eluates (1981)

T lymphocytes positively identified by alphanaphthyl acetate esterase (ANAE) (70%) were localized in perivascular "cuffs" in rheumatoid synovia. ANAE-negative lymphocytes (B lymphocytes) were primarily within the reactive lymphoid centers, whereas intracellular Ig-expressing plasma cells were outside the centers. Lysozyme of diffuse ANAE expressing mononuclear phagocytes (5-15%) were diffusely dispersed, but were seldom found in the lymphoid centers. There were few granulocytes (10%). On elution, plasma cells and lymphocytes were lost. Most granulocytes and mononuclear phagocytes in the eluate were immunoglobulin-positive. The in situ architecture is compatible with active immunologic inflammation and T-dependent immunoglobulin synthesis.
Vascular Plants of the Wichita Mountains (2002)

This list is an effort to update a popular list of the vascular plants of the Wichita Mountains Wildlife Refuge prepared by the author approximately ten years ago. The earlier work was compiled from lists published by Eskew (1938), Osborn and Allen (1949) and from studies of several regional herbaria.
FRM: Towards a Semantic Platform for Fair Content Distribution (2008)

Fair use policy allows legal owners to share products they bought with their acquaintance; it is based on the assumptions that the owners pass an original product and they cannot use it at the same time. In the digital world, we can hardly apply those assumptions since they are based on a physical availability. Furthermore, digital content providers want to have control over the distribution of their products; thus, Digital Rights Management (DRM) systems do not assist and even forbid sharing. We present Fair Rights Management (FRM) that is our work towards fair use in the digital world. We propose taking advantage of social networks and terms negotiations. We illustrate our approach by extending existing solutions with semantic descriptions. We describe how to apply and implement the proposed improvements in the standard DRM model. Finally, we evaluate our proposition with the most common fair use scenarios.

Anti-inflammatory activity of roots of<i>Achyranthes aspera</i> (2009)

This study investigated the anti-inflammatory potential of the alcohol extract of Achyranthes aspera Linn. (Amaranthaceae) in Wistar rats after oral administration (50, 100, and 200 mg/kg). This was done using the carrageenan-induced paw edema method (acute inflammatory model) and cotton pellet granuloma test (chronic inflammatory model). The alcohol extract showed significant suppressed granuloma formation. Collectively, these data demonstrate promising anti-inflammatory activity against both acute and chronic inflammation. In addition, inhibition of prostaglandins and bradykinins may play a role. This study revealing the promising anti-inflammatory activity of Achyranthes aspera roots has been carried out scientifically for the first time.
Language shift and language maintenance in mixed marriages: a case study of a Malaysian-Chinese family : Language maintenance or language shift: focus on Malaysia (2003)

Language choice is determined by linguistic considerations as well as by external and internal factors. Location, community structure, situation. topic, and participants are some of the factors that have been mentioned. Harrison and Piete (1980) point out that in bilingual families language choice is determined by the mothers. The mother's choice is in turn determined by socioeconomic considerations, etc. This paper sets out to study the issue of language choice and ultimately language shift and maintenance in a mixed marriage. This study is a case study of the author's family, where mixed marriages have occurred over different generations. The methodology employed is one of observation and oral interview. The premise presented by Harrison and Piete (1980) is used as a framework.
Comparison on the Antibody Response and Influenced Factors of Hepatitis B Vacine Made by Recombinant Dexyribonucleic Acid Techniques among Adults (2013)

Objective To compare the antibody response induced by 20 g hepatitis B vaccine (HepB) made by recombinant dexyribonucleic acid (DNA) techniques in saccharomyces cerevisiae yeast (HepB-SCY) and 20 g HepB made by recombinant DNA techniques in Chinese hamster ovary (CHO) cell (HepB-CHO) and influenced factors among the adults .Methods Healthy adults who were negative for hepatitis B virus (HBV) surface antigen (HBsAg), antibody to HBsAg (Anti-HBs) and antibody to HBV core antigen (Anti-HBc) were selected from Zhangqiu county Shandong province. They were divided into two groups randomly and were vaccinated following the schedule of 0-1-6 with 20 g HepB-SCY and 20 g HepB-CHO respectively . Questionare investigation was made and blood samples were collected for eachperson. Anti-HBs was detected by chemiluminescence microparticle imunoassay (CMIA) . Seroconversion rate and geometric mean concentrations (GMC) of Anti-HBs were compared between the two groups . Multivariate analysis was used to find the relationship between the kind of HepB and seroconversion rate or GMC of Anti-HBs after debugging the other influencing factors including age , gender , body mass index , smoking history and drinking history .Results 2011 adults received 20 g HepB-SCY (HepB-SCY group)and 2290 adults received 20 g HepB CHO (HepB-CHO group) . In HepB-SCY group , the rates of non -, low -, normal-and high-response were 14.22 %, 15.57 %, 29.09 % and 41.12 % respectively. In HepB-CHO group , the corresponding rates were 9.35 %, 19.08 %, 33.97 % and 37.60 % respectively. The above four rates showed significant differences between the two groups (2 =5.44-23.11 ,P 0.01). The GMCs of Anti-HBs were 270.39mIU/ml (95 % CI : 233.33 mIU/ml-313.32 mIU/m1) and 312.67mIU/ ml (95 % CI : 278.28 mIU/m1-351.32 mIU/m1) in 20 g HepB-CHO group and in 20 g HepB-CHO group respectively and the confidence interval was not statistically significant (u =1.52 ,P =0.13). Multivariate analysis showed that the no-response rates were signiticantly different between the two groups even after debugging the other influencing factors .Conclusion A high Anti-HBs response could be achieved by three doses of 20 g HepB-SCY or 20 g HepB-CHO among the adults . The non-response rate seems a little higher after vaccinating with 20 g HepB-SCY than with 20 g HepB-CHO .
Vascular endothelial growth factor expression in human neuroblastoma: Up-regulation by hypoxia (1999)

Enhanced angiogenesis apparently contributes to the poor clinical outcome of human neuroblastoma, but the mechanisms have remained unclear. We report here that cultured human neuroblastoma cells express a bioactive endothelial cell growth factor indistinguishable from the angiogenesis stimulator vascular endothelial growth factor (VEGF). VEGF is present in neuroblastoma but not vascular endothelial cells, whereas the corresponding VEGF receptors (Flt-1 and Flk-1/KDR) are expressed in endothelial but not neuroblastoma cells. Exposure of neuroblastoma cells to hypoxia induces a marked increase in bioactive VEGF. VEGF is also present in human neuroblastoma specimens, with substantial amounts in apparently hypoxic neuroblastoma cells, eventually accumulating in tumor microvessels. Our results indicate that VEGF (i) is present in human neuroblastomas, (ii) is up-regulated by tumor hypoxia and (iii) may stimulate neuroblastoma angiogenesis by paracrine mechanisms, thereby contributing to the progression of human neuroblastomas. We suggest that inhibition of VEGF activity may represent a novel approach for the therapy of human neuroblastoma. Int. J. Cancer 81:113–117, 1999. © 1999 Wiley-Liss, Inc.
Maximum-likelihood receiver for four-dimensional signaling schemes corrupted by ISI (1992)

A maximum-likelihood decision-directed receiver structure is derived for a data transmission system which employs quadrature-quadrature phase shift keying (Q/sup 2/PSK) as the modulation scheme. The receiver is derived by treating the problem of sequence decision, sample timing, and carrier phase as a composite estimation problem. It is shown that the resulting maximum-likelihood estimates (MLEs) are asymptotically unbiased, and the variances of these estimates are derived. In this receiver, symbol detection is carried out by means of a modified Viterbi algorithm (MVA) while a parallel synchronizer is used for carrier phase and delay recovery. As a measure of performance, an error-event probability bound is derived for the MVA. The effect of intersymbol interference, (ISI) present at the two matched filters' outputs, on the error bound is analyzed and illustrated. It is shown that the resulting MVA and the parallel estimator are well suited for systolic array implementation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Spectromètre interférentiel multiplex pour mesures infra-rouges sur les étoiles (1958)

Cet interféromètre a été construit en vue de l'emploi au foyer coudé du télescope de 90 cm de l'Observatoire de Cambridge. Il utilise une lame séparatrice en fluorine, recouverte d'une couche λ/4 de ZnSe et des trièdres réfléchissants. Les faisceaux tombent sur les trièdres excentriquement et sont renvoyés en sens inverse selon la même direction avec un déplacement latéral un peu supérieur au diamètre du faisceau, de sorte que les deux faisceaux sortants sont tous deux utilisables. Ces deux faisceaux tombent sur les deux faces réfléchissantes d'un modulateur tournant, qui se comporte comme l'analogue optique d'un interrupteur inverseur; puis sur deux cellules au sulfure de plomb montées en opposition ; on mesure ainsi la quantité d'énergie transférée par les interférences d'un faisceau sur l'autre. L'un des trièdres possède des réglages micrométriques selon les trois coordonnées et l'autre est déplaçable au moyen d'une vis micrométrique et d'un levier à deux étages donnant un rapport de réduction de 100 fois. La vitesse de déplacement normale est de 60 λ en 10 minutes. Au cours d'observations préliminaires une douzaine d'étoiles allant jusqu'aux magnitudes visuelles 4 ou 5 ont été mesurées avec un pouvoir de résolution de l'ordre de 60. Les transformations de Fourier ont été faites numériquement sur des bandes de Lipsom-Beevers. On montre quelques-uns des spectres obtenus.
CAD GENERAION OF ACCIDENT DIAGRAMS FOR LOCAL AGENCIES (1987)

This paper reviews one such issue, safety, focusing on the development of a user-interface with a microcomputer CAD system. With this interface, the system is used to generate collision diagrams by users with limited knowledge of microCAD systems. Because the generation of collision diagrams is typically done by hand, and on a recurring basis, it is an ideal candidate for automation. With the help of AutoCAD, a microCAD software package, accident analyses can be done more efficiently in that diagrams can be produced, updated, and recorded more quickly and in a more organized manner than by hand.
Split virus influenza vaccination in children: an evaluation of efficacy (1985)

Twenty-seven children aged between 4 and 13 years were given two injections of a split virus influenza vaccine (MFV-Ject, Institut Merieux) at a dose of 0.5 ml and an interval of 1 month. Each vaccination contained A/Philippines/2/82 (H3 N2) 10 micrograms HA, A/Brazil/11/78 (H1 N1) 10 micrograms HA, B/Singapore/222/79 15 micrograms HA. The overall serological response was good although the B group virus produced slightly less response; however, no children were seropositive to B prior to vaccination, reflecting a low previous exposure. Children aged over 10 years showed a generally higher serological response. Side-effects were minimal. A favourable reactogenicity/efficacy ratio was found.
On a nonvolatile memory cell based on micro-electro-mechanics (2002)

An integrated micro-electro-mechanical nonvolatile memory cell is investigated. It essentially consists of a surface-micromachined bridge that is longitudinally stressed so that it buckled and becomes mechanically bistable. This bistable bridge performs the memory function. The read and write operation is performed by sensing the capacitance of the bridge and by electrostatically switching the bridge from one stable state into the other, respectively. The performance of such a device has been roughly estimated by a simple analytical model and experimental samples have been fabricated using a slightly adapted MOS process. The results appear promising.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Characterization of Corticotropin-Releasing Hormone neurons in the Paraventricular Nucleus of the Hypothalamus of Crh-IRES-Cre Mutant Mice (2013)

Corticotropin-releasing hormone (CRH)-containing neurons in the paraventricular nucleus of the hypothalamus (PVN) initiate and control neuroendocrine responses to psychogenic and physical stress. Investigations into the physiology of CRH neurons, however, have been hampered by the lack of tools for adequately targeting or visualizing this cell population. Here we characterize CRH neurons in the PVN of mice that express tdTomato fluorophore, generated by crosses of recently developed Crh-IRES-Cre driver and Ai14 Cre-reporter mouse strains. tdTomato containing PVN neurons in Crh-IRES-Cre;Ai14 mice are readily visualized without secondary-detection methods. These neurons are predominantly neuroendocrine and abundantly express CRH protein, but not other PVN phenotypic neuropeptides. After an acute stress, a large majority of tdTomato cells express neuronal activation marker c-Fos. Finally, tdTomato PVN neurons exhibit homogenous intrinsic biophysical and synaptic properties, and can be optogenetically manipulated by viral Cre-driven expression of channelrhodopsin. These observations highlight basic cell-type characteristics of CRH neurons in a mutant mouse, providing validation for its future use in probing neurophysiology of endocrine stress responses.
The effect of calcium phosphate ceramic composition and structure on <i>in vitro</i> behavior. I. Dissolution (1993)

Synthetic calcium phosphate ceramic (CPC) surfaces can be transformed to a biological apatite through a sequence of reactions which include dissolution, precipitation, and ion exchange. By virtue of the reactions being material-dependent, it is important to determine parametric rate effects. In this study we focused on the effect of stoichiometry and crystal structure of CPCs on the dissolution kinetics. Monophase, biphase, and multiphase CPCs with a Ca/P ratio equal to or greater than 1.5 were studied. The experiments were performed in a calcium- and phosphate-free Tris buffer solution at pH 7.3. The dissolution behavior of the CPCs studied was found to vary over a wide range. The dissolution rate of the monophase CPCs increased in the order of stoichiometric hydroxyapatite, calcium deficient hydroxyapatite, oxyhydroxyapatite, beta-tricalcium phosphate, alpha-tricalcium phosphate, and tetracalcium phosphate. Dissolution of biphase and multiphase CPCs increased prorated the concentration of more soluble component.
Coverage-Based Testing on Embedded Systems (2007)

One major issue of code coverage testing is the overhead imposed by program instrumentation, which inserts probes into the program to monitor its execution. In real-time systems, the overhead may alter the program execution behavior or impact its performance due to its strict requirement on timing. Coverage testing is even harder on embedded systems because of their critical and limited memory and CPU resources. This paper describes a case study of a coverage-based testing method for embedded system software focusing on minimizing instrumentation overhead. We ported a code coverage-based test tool to an in-house embedded system, IP phone. In our initial experiments, we found that this tool didn 't affect the behavior of the program under test.
Prediction of Ionic Liquid Properties. I. Volumetric Properties as a Function of Temperature at 0.1 MPa (2008)

The prediction of molar volumes and densities of several ionic liquids has been achieved using a group contribution model as a function of temperature between (273 and 423) K at atmospheric pressure. It was observed that the calculation of molar volumes or densities could be performed using the “ideal” behavior of the molar volumes of mixtures of ionic liquids. This model is based on the observations of Canongia Lopes et al. (J. Phys. Chem. B 2005, 109, 3519–3525) which showed that this ideal behavior is independent of the temperature and allows the molar volume of a given ionic liquid to be calculated by the sum of the effective molar volume of the component ions. Using this assumption, the effective molar volumes of ions constituting more than 220 different ionic liquids were calculated as a function of the temperature at 0.1 MPa using more than 2150 data points. These calculated results were used to build up a group contribution model for the calculation of ionic liquid molar volumes and densities with an estimated repeatability and uncertainty of 0.36 % and 0.48 %, respectively. The impact of impurities (water and halide content) in ionic liquids as well as the method of determination were also analyzed and quantified to estimate the overall uncertainty.
Random Sequencing of <i>Paramecium</i> Somatic DNA (2002)

We report a random survey of 1 to 2% of the somatic genome of the free-living ciliate Paramecium tetraurelia by single-run sequencing of the ends of plasmid inserts. As in all ciliates, the germ line genome of Paramecium (100 to 200 Mb) is reproducibly rearranged at each sexual cycle to produce a somatic genome of expressed or potentially expressed genes, stripped of repeated sequences, transposons, and AT-rich unique sequence elements limited to the germ line. We found the somatic genome to be compact (>68% coding, estimated from the sequence of several complete library inserts) and to feature uniformly small introns (18 to 35 nucleotides). This facilitated gene discovery: 722 open reading frames (ORFs) were identified by similarity with known proteins, and 119 novel ORFs were tentatively identified by internal comparison of the data set. We determined the phylogenetic position of Paramecium with respect to eukaryotes whose genomes have been sequenced by the distance matrix neighbor-joining method by using random combined protein data from the project. The unrooted tree obtained is very robust and in excellent agreement with accepted topology, providing strong support for the quality and consistency of the data set. Our study demonstrates that a random survey of the somatic genome of Paramecium is a good strategy for gene discovery in this organism.
