RITA - Robotized Inspection by Thermography and Advanced processing for the inspection of aeronautical components (2014)

Active thermography is often performed on a static configuration where all elements of the thermographic system, i.e. the infrared camera, the energy source and the inspected object, are standing still with respect to each other. This is very useful for the application of signal processing techniques in order to improve defect detection and characterisation. Under this configuration, the large surfaces typical of some aeronautical components, are inspected in a series of static tests that at the end are assembled together on a single reconstructed mosaic image comprising the results for the entire inspected area. However, with the fast development of innovative and ever more complex-shaped parts, the alternative dynamic active thermography configuration is gaining attention. In this case, the component of interest is inspected in motion and the acquired data can be reorganized as a pseudo-static sequence, similar to classic static data, in order to perform advanced signal processing, if required. In this work, line scan thermography inspection was investigated for the assessment of an aerospace reference panel in the framework of the Canadian-Belgian collaborative project RITA (Robotized Inspection by Thermography and Advanced processing).
Augmented Reality Visualization System for Intravascular Neurosurgery (1998)

We aimed to construct an augmented reality-based visualization system to support intravascular neurosurgery and evaluate it in clinical environments. Three-dimensional (3D) vascular models are overlaid on motion pictures from X-ray fluoroscopy by 2D/3D registration using fiducial markers. The models are reconstructed from 3D data obtained from X-ray computed tomographic angiography or from magnetic resonance angiography using the marching-cube algorithm. Intraop-erative X-ray images are mapped as texture patterns on a screen object which is displayed with the vascular models. Distortion of X-ray fluoroscopy is eliminated by a new technique of screen mesh deformation. A quantity called reprojection distance was introduced to evaluate the reliability of the displayed images. It predicts the maximum registration error around the registered objects. Analyses of reprojection distances were performed using synthetic data consisting of marker coordinates with 2D or 3D errors. The tolerance of reprojection distance for the clinical environment was determined to be 3.0 mm. The system was tested in two clinical cases in which reprojection distances of 2.6 and 2.09 mm were obtained. Construction and evaluation of our prototype system were successfully carried out. Further development is planned employing a range sensor to permit markerless registration.
A case of hypogammaglobulinemia with a complication of hepatitis B with bridging necrosis (1984)

A 23 year-old male who had a past history of recurrent infection, was admitted to our hospital with the complaint of general malaise and fever. Laboratory examination revealed IgG 430mg/dl, IgA 62ml/dl and IgM 43mg/dl with hypertransaminasenemia, in conjunction with HBs-Ag (+) and HBe-Ag (+). Liver biopsy specimen showed a lobular massive necrosis with proliferation of the small biliary ducts and with slight lymphocytosis and plasmacytosis.Immunological examination with peripheral lymphocytes revealed the decrease of the immunoglobulin-secreting cells detected by plaque-forming-cell assay and marked reduction of OKT 4 (+) cells and of surface immunoglobulin bearing cells. In vitro culture of the unfractionted peripheral lymphocytes from this patient in the presence of pokeweed mitogen (PWM) showed a decreased immunoglobulin production when compared with the normal control. In addition, In vitro co-culture of B cells of this patient and T cells of the control in the presence of PWM revealed the decreased production of immunoglobulin, suggesting the impared function of B cells of this patient, in addition to the reduced number of B cells. In the same type of experiments, the helper function of T cells of this patient to In vitro Immunoglobulin synthesis, was found to be impared.Some discussions have been made concerning the hypo γ-globulinemia in cojunction with severe liver disease and the lymphocyte dysfunction of this patient.
Les comptes de patrimoine (1979)

Las cuentas patrimoniales - Las cuentas patrimoniales constituyen una novedad, tanto en Francia como en el extranjero. Los resultados propuestos dependen, desde luego, de la definición contable seleccionada : el patrimonio, limitándolo únicamente al patrimonio ffsico de los que residen en territorio metropolitano, iguala el valor de los activos físicos y financieros menos los compromisos financieros. Dependen además de la medida que se toma de ellos : valor adquisitivo, valor de substitución, de realización. Si bien esta primera experiencia puede presentar lagunas, permite cuando menos dar una respuesta a preguntas que, a primera vista, parecen sencillas : ¿ quien disfruta este patrimonio ? ¿ de que esta compuesto ? ¿ como evolucionó de 1971 a 1976 ? y ¿ quien finanza a quien ? Una vez llevada a cabo la valorización de sus diversos componentes (tierras y terrenos, viviendas, demis edificaciones, material, stocks, activos no corporales, stock de préstamos financieros, titulos), el patrimonio nacional se estima, con fecha del 31 de diciembre de 1976, a 6,9 billones de francos, lo cual representa cuatro anos de producto nacional, y los hogares son poseedores de los dos tercios.
Heterogeneous catalytic insertion mechanism of the C2 oxygenate formation (1985)

Experiments on the mechanism of formation of ethanol and acetaldehyde from CO–H2(2:1), performed by adding methylene chloride to the mixture, show that C2 oxygenate formation proceeds via CO insertion.
Stereochemical Control in the Still-Wittig Rearrangement Synthesis of Cyclohexyl (Z)-Alkene Inhibitors of Pin1 (2015)

Three stereoisomeric inhibitors of Pin1: (2R,5S)-, (2S,5R)- and (2S,5S)-Ac-pSer-Ψ[(Z)CH = C]-pipecolyl(Pip)-2-(2-naphthyl)ethylamine 1, that mimic L-pSer-D-Pro, D-pSer-L-Pro, and D-pSer-D-Pro amides respectively, were synthesized by a 13-step route. The newly formed stereogenic centers in the pipecolyl ring were introduced by Luche reduction, followed by stereospecific [2,3]-Still-Wittig rearrangement. The (Z)- to (E)-alkene ratio in the rearrangements were consistently 5.5 to 1. The stereochemistry at the original Ser α-carbon controlled the stereochemistry of the Luche reduction, but it did not affect the stereochemical outcome of the rearrangement, which consistently gave the (Z)-alkene. The epimerized by-product, (2S,5S)-10, resulting from the work-up after Na/NH3 debenzylation of (2S,5R)-9, was carried on to the (2S,5S)-1 isomer. Compound (2S,5S)-10 was resynthesized from the Luche reduction by-product, (2R,3R)-3, and the stereochemistry was confirmed by comparison of the optical rotations. The IC50 values for (2R,5S)-1, (2S,5R)-1 and (2S,5S)-1 Pin1 inhibition were: 52, 85, and 140 μM, respectively.
A Second-Generation Single-Chip Stereo Imager (2006)

A second-generation stereo vision chip, fabricated in a 0.35mum 4M2P CMOS process and incorporating two 128 times 128 pixel linear current-mode imagers and current-mode disparity computation circuitry, is presented. Parallel computation of the sum-of-absolute-difference matching metric allows the chip to produce 114 times 124 pixel depth maps at 30 frames per second, performing 2.2 billion operations per second, while using 10.1mA from a 3.3V supply
P‐glycoprotein in blood CD4 cells of HIV‐1‐infected patients treated with protease inhibitors (2003)

P-gp expression in peripheral CD4 blood cells does not seem to be enhanced by PI treatment and does not seem to be linked particularly to virological failures. These facts do not preclude of the role of P-gp on PI absorption or efficacy in other compartments of the body such as gut, lymph nodes or brain in HIV-1 PI-treated patients.
Blastomere segmentation and 3D morphology measurements of early embryos from Hoffman Modulation Contrast image stacks (2010)

Monitoring of embryos is an important activity during In Vitro Fertilization (IVF) procedures. A critical stage is that of the early embryo, which is formed by a small number of cells (blastomeres): the morphology of such cells is considered to be a powerful indicator of the embryo viability. We deal with the challenging problem of automatically segmenting the different blastomeres in the early embryo while simultaneously determining their depth, by processing a Z-stack of images acquired by means of an Hoffman Modulation Contrast (HMC) microscope.We discuss experimental results on 53 embryo image stacks, and elaborate on the advantages and limitations of our approach, also briefly describing it is being integrated in the workflow of an IVF laboratory.
Use of the optical admittance function and its WKB approximation to simulate and evaluate transmittance spectra of graded-index colloidal films (2007)

A method is presented for the simulation of transmittance spectra of graded-index dielectric layers deposited on a transparent substrate of finite thickness, and the simulation process is applied to films of silica and zinc oxide nanoparticles. The method is based on the optical admittance by solving its differential equation for an appropriate refractive index profile. When the refractive index changes with depth z according to the function N(z) = N(0)/(1+z/ζ)2, an exact solution exists which is equivalent to the WKB (geometric optical) approximate solution derived for the electromagnetic field in weakly inhomogeneous media. Using this solution allows us to characterize transparent graded-index films by two optical parameters—the mean refractive index and the grade of inhomogeneity, in addition to the film thickness through a fast curve fitting process.
Synthesis and Biological Evaluation of Analogues of Cryptolepine, an Alkaloid Isolated from the Suriname Rainforest (1999)

Bioassay-guided fractionation of an extract of a mixture of Microphilis guyanensis and Genipa americanacollected in the rainforest of Suriname yielded the known alkaloid cryptolepine (2) as the major active compound in a yeast bioassay for potential DNA-damaging agents; the same compound was later reisolated from M. guyanensis. The structure of cryptolepine was identified unambiguously by spectral data and by its total synthesis. Several cryptolepine derivatives (3-29, 32-41) were synthesized based on modifications of the C-2, N-5, N-10, and C-11 positions. Two cryptolepine dimers (30, 31) were also prepared. The structure modifications did not result in compounds with a higher potency than the parent compound cryptolepine in the yeast assay system, although some derivatives did show significant activity. Selected compounds (6, 7, 17, 22, 23, 26, and 27) were also tested for cytotoxicity in mammalian cell culture, and two compounds showed significant cytotoxic activity.

Mobile Historie Tails in Nucleosomes (1989)

The 13C NMR spectrum of isolated nucleosome core particles contains many sharp resonances, including resonances of alpha- and beta-carbons, indicating that certain terminal segments of histones rich in basic residues are highly mobile (Hilliard, R. R., Jr., Smith, R. M., and Rill, R. L. (1986) J. Biol. Chem. 261, 5992-5998). Specific histone termini can be removed sequentially from nucleosome core particles by mild treatment with alpha-chymotrypsin or chymotrypsin plus trypsin (Rosenberg, N. L., Smith. R. M., and Rill, R. L. (1986) J. Biol. Chem. 261, 12375-12383). Comparisons of the 13C NMR spectra of native and several partially proteolyzed core particles indicated that a minimum of residues 1-20 of H3 and 1-11 and 118-128 of H2a are contained in mobile segments of native cores. H4 did not appear to contribute to the resonances from mobile histone segments, but a possible contribution of H2b residues 1-16 could not be ruled out. The 13C NMR spectra of oligonucleosomes containing and lacking lysine-rich histones (H1, H5) were similar to each other and to that of native nucleosome cores both when the oligonucleosomes were in an extended conformation at low ionic strength and when they were in a more compact conformation at higher ionic strength. This similarity suggests that histones H1 and H5 must be largely immobilized upon chromatin binding and that the segments of core histones that are mobile in isolated nucleosome cores are not strongly bound to adjacent linker regions in intact chromatin, and are not immobilized by compaction to the degree achieved in 50 mM phosphate buffer.
The influence of the age of the host on the incidence of blood-borne metastases. (1961)

Summary The influence of the age of the host on the incidence of metastasis has been studied in mice given injections intravenously of Ehrlich ascites tumor cells. The results indicate that ( a ) the resistance of mice to the establishment of metastases decreases with age and ( b ) the influence of age is apparent only at relatively low doses of tumor cells.
Amino Acid Replacement Studies of Human Cytochrome c by a Complementation System Using CYC1 Deficient Yeast (1988)

Various in vitro mutated human cytochrome c genes which encode displaced amino acid residues at the 14th, 17th, 28th, 37th, 38th, 56th, and/or 84th residues were constructed, and their degrees of complementation of yeast CYC1 deficiency were examined. Invariant Cys-17 and Arg-38 could not be replaced by alanine and tryptophan, respectively, without function impairment. Cytochrome c containing Ala-14 instead of conserved Cys-14, Gly-38 or Lys-38 instead of Arg-38, and Ser-84 instead of invariant Gly-84 were partly functional. These results indicate that these invariant or conserved residues are important. Cytochromes c containing Cys-56 instead of native Gly-56 was partly functional. Cytochrome c containing Arg-37 and Gly-38 instead of Gly-37 and Arg-38 was slightly functional. Replacement of variable Thr-28 and Gly-37 by Ile-28 and Arg-37, respectively, produced no effects. Our results are as a whole consistent with the view that conserved residues are important and variable residues are less important for cytochrome c to function.
Isolation, Enumeration, and Expansion of Human Mesenchymal Stem Cells in Culture (2012)

Human bone marrow (BM) contains a population of non-hematopoietic stem cells also termed stromal cells, mesenchymal cells or multipotent mesenchymal stromal cells (MSCs). These cells have unique stem cell-like properties including their ability to self-renew, differentiate into multiple tissue types, and modulate immune cell responses through paracrine effects. These properties have positioned mesenchymal cells as biological agents in clinical trials for various diseases since the 1990s. Mesenchymal cells have been isolated from various tissues and cultured using various media and methods resulting in a lack of standardization in culture methods for these cells. Consequently, cells cultured in different laboratories exhibit different characteristics of MSC-like cells. This chapter outlines protocols for optimal isolation, enumeration, and expansion of human MSCs from BM in fetal bovine serum (FBS)-containing medium, as well as in xeno-free medium.
Base‐Stabilized Boryl and Cationic Haloborylene Complexes of Iron (2013)

The synthesis of base-stabilized boryl and borylene complexes is reported. An N-heterocyclic carbene (NHC)-stabilized iron-dihydroboryl complex was prepared by two different routes including methane liberation and salt elimination. A range of base-stabilized iron-dichloroboryl complexes was prepared by addition of Lewis bases to boryl complexes. Base-stabilized, cationic monochloroborylene complexes were synthesized from these boryl complexes by halide abstraction by using weakly coordinating anions.
Unconventional Origin of Metal Ion Rescue in the Hammerhead Ribozyme Reaction:  Mn<sup>2+</sup>-Assisted Redox Conversion of 2‘-Mercaptocytidine to Cytidine (2000)

A specific oxygen atom in RNA is identified as a ligand for a metal ion when sulfur substitution of that atom shifts the metal ion specificity of the RNA-mediated process to a more thiophilic metal. Extensive discussion and debate have centered around whether a metal ion activates the 2‘-oxygen nucleophile during the phosphotransesterification reaction catalyzed by the hammerhead ribozyme (HH). To test this possibility, we probed the metal ion specificity of HH reactions using a substrate that contained 2‘-mercaptocytidine at the cleavage site. This substrate is generated in situ from a disulfide-protected precursor by treatment with tris(carboxyethyl)phosphine (TCEP). In HH reactions with this substrate, phosphotransesterification does not occur when Mg2+ is present as the only divalent cation but does occur in the presence of Mn2+. These results are consistent with a direct interaction between the metal ion and the nucleophile. However, further analysis reveals that this switch in metal ion specificity does not arise because Mn2+ coordinates sulfur more readily than Mg2+ does, but because under the assay conditions, the 2‘-mercaptocytidine residue is converted to a mixture of cytidyl-1-β-d-arabinofuranoside and cytidyl-1-β-d-ribofuranoside, the natural substrate for the ribozyme. This conversion occurs in the absence of HH ribozyme, requires Mn2+ (or Co2+), O2, and TCEP, and is inhibited by a free radical scavenger. The mechanism presumably involves a multistep free radical process, in which the key step is homolytic fission of the C2‘-sulfur bond induced by TCEP. The putative 2‘-carbon radical then reacts with an oxygen species to produce the cytidyl-1-β-d-arabinofuranoside and ribocytidine products. To our knowledge, this chemical transformation is unprecedented in the literature and represents a new reaction for nucleic acids. If O2 is excluded from the HH reactions, the 2‘-sulfur is not modified in the presence of Mn2+ but is still blocked in the phosphotransesterification reaction, both in the forward direction as the mercapto (−SH) group or in the reverse direction as part of a cyclic phosphorothiolate. Although we are unable to provide evidence for metal ion activation of the nucleophile in the HH ribozyme reaction, this work establishes the groundwork for further use of 2‘-mercaptonucleotides in biochemical analyses.
EPR spectra of Cr<sup>3+</sup>centres in crystals of Cs<sub>2</sub>CdCl<sub>4</sub> (1981)

When crystals of Cs2CdCl4 (K2NiF4-type structure) are doped with Cr3+ a number of different impurity centres are formed which are readily distinguishable by EPR spectroscopy. The doped crystals contain both compensated and uncompensated Cr3+ centres. The resonances from the uncompensated Cr3+ exhibit axial symmetry about the crystallographic c axis. In the compensated centres the charge discrepancy of the Cr3+ appears to be balanced by a Cs+ vacancy. A centre with axial symmetry and a centre with rhombic symmetry can be attributed to Cr3+ ions compensated by Cs+ vacancies. If Li+ or Na+ are doped into the Cs2CdCl4 crystals along with Cr3+, a new rhombic centre is observed where the charge discrepancy is balanced by one of the small monovalent ions. The assignment and analysis of the EPR spectra from the doped crystals are discussed in detail.

Marking Soil Bacteria with <i>lacZY</i> (1994)

This chapter provides a detailed description of all the indirect molecular genetic methods available to mark soil bacteria. Marking bacteria necessarily involves a change in the phenotype and genotype of the parental strain. The most recent version of the lacZY marking system, the IncQ-based, monocomponent transposition system developed by Monsanto scientists allows such a change. The lacZY system is, in essence, a triparental mating of three bacterial components-donor, helper, and recipient cells. Genetic confirmation of the transposition event, i.e., the physical demonstration of the insertion of lacZY into the recipient's chromosome, is done by DNA hybridization analysis. Only brief mention has been made of the stability of the lacZY marker, and that only in reference to strains marked by transforming plasmids. Once the lacZY-marked inoculum is applied to nonsterile soil, it must be recovered from soil or root washes. The IncO-based system offers several distinct advantages for marking a wide range of soil bacteria.
