Contribution à l'étude des glacis : la bordure occidentale de la plaine du Forez. (1977)

À partir de l'analyse des matériaux qui en jalonnent les pentes (couvertures de cailloutis et de leur matrice argilo-sableuse), les formes topographiques régulières qui marquent parfois le contact entre les monts du Forez et la plaine de Montbrison nous paraissent pouvoir être rapprochées, dans leur dynamique de mise en place, des glacis d'érosion en roche tendre des pourtours de la Méditerranée. Le débat de leur morphogenèse sous climat chaud à la fin du Tertiaire ou sous climat froid au Quaternaire est ouvert.
Expression of cyanobacterial and higher-plant ribulose 1,5-bisphosphate carboxylase genes in <i>Escherichia coli</i> (1986)

Abstract Expression strategies for the synthesis of higher-plant and cyanobacterial RuBP carboxylase genes in Escherichia coli have been developed to facilitate the study of the assembly pathway and properties of the enzyme’s large (L) and small (S) subunit proteins. The genes for the L and S subunits of the RuBP carboxylase of wheat and of a cyanobacterium, Synechococcus 6301 have been cloned into bacteriophage and plasmid vectors such that they are transcribed and translated in E. coli. To date no RuBP carboxylase activity has been detected in extracts prepared from E. coli cells synthesizing the wheat L and S subunits, although both gene products were present and soluble. Sucrose gradient analysis of cell extracts from E. coli synthesizing both L and S demonstrated that the soluble wheat L polypeptide was present as a large protein aggregate that contained no S subunits. With the cloned cyanobacterial genes, RuBP carboxylase activity could be recovered in E. coli cell extracts when the L and S gene products were synthesized from genes present on the same, or separate, replicons. Solubility and sedimentation studies of the cyanobacterial L subunits synthesized in the absence of S showed that the L subunit was soluble and present in E. coli as an L8 structure. The E. coli extracts containing only the L subunit exhibited no detectable RuBP carboxylase activity. Infection of the E. coli cells containing L subunits with an M13 phage expressing the cyanobacterial S gene led to the assembly of functional RuBP carboxylase in these cells. This demonstrates the essential role of the S subunit in allowing the formation of an active enzyme.

Relationship of cyclosporin and sirolimus blood concentrations regarding the incidence and severity of hyperlipidemia after kidney transplantation (2006)

The influence of drug concentrations on the development of persistent posttransplant hyperlipidemia was investigated in 82 patients who received cyclosporin A (CsA) and prednisone plus sirolimus (SRL) (52) or azathioprine (AZA) (30) during the first year after transplantation. Blood levels of CsA and SRL, daily doses of AZA and prednisone, and cholesterol, triglyceride, and glucose concentrations were determined during each visit (pretransplant and 30, 60, 90, 120, 180, and 360 days posttransplant). Persistent hyperlipidemia was defined as one-year average steady-state cholesterol (CavCHOL) or triglyceride (CavTG) concentrations above 240 and 200 mg/dL, respectively. Mean cholesterol and triglyceride concentrations increased after transplantation (P < 0.01) and were higher in patients receiving SRL compared to AZA (P < 0.001). Patients receiving SRL showed a significantly higher number of cholesterol (> 229 or > 274 mg/dL) and triglyceride (> 198 or > 282 mg/dL) determinations in the upper interquartile ranges. CsA and SRL interquartile ranges correlated with cholesterol concentrations (P = 0.001) whereas only SRL interquartile ranges correlated with triglyceride concentrations (P < 0.0001). Only pretransplant cholesterol concentration > 205 mg/dL was independently associated with development of persistent hypercholesterolemia (CavCHOL > 240 mg/dL, relative risk (RR) = 20, CI 3.8-104.6, P = 0.0004) whereas pretransplant triglyceride concentration > 150 mg/dL (RR = 7.2, CI 1.6-32.4, P = 0.01) or > 211 mg/dL (RR = 19.8, CI 3.6-107.9, P = 0.0006) and use of SRL (RR = 3, CI 1.0-8.8, P = 0.0049) were independently associated with development of persistent hypertriglyceridemia (CavTG > 200 mg/dL). Persistent hypercholesterolemia was more frequent among patients with higher pretransplant cholesterol concentrations and was dependent on both CsA and SRL concentrations. Persistent hypertriglyceridemia was more frequent among patients with higher pretransplant triglyceride concentrations and was dependent on SRL concentrations.

High-resolution computational spectral imaging with photon sieves (2014)

Photon sieves, modifications of Fresnel zone plates, are a new class of diffractive image forming devices that open up new possibilities for high resolution imaging and spectroscopy, especially at UV and x-ray regime. In this paper, we develop a novel computational photon sieve imaging modality that enables high-resolution spectral imaging. For the spatially incoherent illumination, we study the problem of recovering the individual spectral images from the superimposed and blurred measurements of the proposed photon sieve system. This inverse problem, which can be viewed as a multi frame deconvolution problem involving multiple objects, is formulated as a maximum posterior estimation problem, and solved using a fixed-point algorithm. The performance of the proposed technique is illustrated for EUV spectral imaging through numerical simulations. The results suggest that higher spatial and spectral resolution can be achieved as compared to conventional spectral imagers.
The adenine nucleotide catabolism in nonphosphorylating mitochondria of different tissues. (1989)

The degradation of endogenous adenine nucleotides was compared in mitochondria isolated from mouse and rat liver, rat renal cortex and solid hepatoma. Mitochondria were incubated for 30 min at 37 degrees C in the presence of carboxyatractyloside and oligomycin. In rat liver mitochondria ATP, ADP and AMP were degraded by about 25% each, whereas in kidney and hepatoma mitochondria a rapid decline of ATP and ADP but no change in the AMP contents were observed. Main products formed were adenosine, inosine and hypoxanthine in all mitochondria examined. Compartment studies revealed that the main route of intramitochondrial adenine nucleotide catabolism seems to proceed via AMP dephosphorylation and subsequent adenosine deamination.
Foveal Lesions Seen in Retinitis Pigmentosa (1977)

A total of 110 patients with retinitis pigmentosa were prospectively and consecutively evaluated for the presence of foveal lesions. Of these 69 (63 percent) patients showed one of two types of separate and distinct bilateral foveal lesions. Forty-seven (43 percent) patients had atrophic-appearing lesions of the retinal pigment epithelium within the fovea of both eyes, and an additional 22 (20 percent) patients showed bitalteral foveal cysts or partial-thickness holes. Of the 22 patients in this last group, 16 showed cystoid macular edema evident on fluorescein angiography.
Impact of longitudinal power budget in coherent systems employing digital back-propagation (2011)

We report the impact of longitudinal signal power profile on the transmission performance of coherently-detected 112 Gb/s m-ary polarization multiplexed quadrature amplitude modulation system after compensation of deterministic nonlinear fibre impairments. Performance improvements up to 0.6 dB (Q(eff)) are reported for a non-uniform transmission link power profile. Further investigation reveals that the evolution of the transmission performance with power profile management is fully consistent with the parametric amplification of the amplified spontaneous emission by the signal through four-wave mixing. In particular, for a non-dispersion managed system, a single-step increment of 4 dB in the amplifier gain, with respect to a uniform gain profile, at ~2/3(rd) of the total reach considerably improves the transmission performance for all the formats studied. In contrary a negative-step profile, emulating a failure (gain decrease or loss increase), significantly degrades the bit-error rate.
Molecular Detection and Quantification of<i>Pythium</i>Species: Evolving Taxonomy, New Tools, and Challenges (2012)

The genus Pythium is one of the most important groups of soilborne plant pathogens, present in almost every agricultural soil and attacking the roots of thousands of hosts, reducing crop yield and quality. Most species are generalists, necrotrophic pathogens that infect young juvenile tissue. In fact, Cook and Veseth have called Pythium the "common cold" of wheat, because of its chronic nature and ubiquitous distribution. Where Pythium spp. are the cause of seedling damping-off or emergence reduction, the causal agent can easily be identified based on symptoms and culturing. In more mature plants, however, infection by Pythium spp. is more difficult to diagnose, because of the nonspecific symptoms that could have abiotic causes such as nutrient deficiencies or be due to other root rotting pathogens. Molecular methods that can accurately identify and quantify this important group are needed for disease diagnosis and management recommendations and to better understand the epidemiology and ecology of this important group. The purpose of this article is to outline the current state-of-the-art in the detection and quantification of this important genus. In addition, we will introduce the reader to new changes in the taxonomy of this group.
Production of chemicals from food processing wastes using a novel fermenter separator. Technical progress report, April 1-June 30, 1986 (1986)

The objective of this project is to perform fundamental, engineering design and operational studies in the area of food processing waste fermentation. This objective will be sought by performing studies to evaluate the fermentation kinetics and nutritional requirement of immobilized cells, to examine different packing materials and energy efficient ethanol separation concentration and recovery methods, and to design and build a pilot plant reactor unit. These data will be used to develop process design models to aid in designing energy efficient and cost effective processes for conversion of food processing wastes into chemicals. During this quarter progress has been made on the literature review, and the laboratory reactor separator studies. The pilot plant construction has been delayed due to problems in equipment procurement. Process design model development is on schedule. 78 refs., 4 figs., 6 tabs.
Impaired theta-gamma coupling in APP-deficient mice (2016)

Amyloid precursor protein (APP) is critically involved in the pathophysiology of Alzheimer's disease, but its physiological functions remain elusive. Importantly, APP knockout (APP-KO) mice exhibit cognitive deficits, suggesting that APP plays a role at the neuronal network level. To investigate this possibility, we recorded local field potentials (LFPs) from the posterior parietal cortex, dorsal hippocampus and lateral prefrontal cortex of freely moving APP-KO mice. Spectral analyses showed that network oscillations within the theta- and gamma-frequency bands were not different between APP-KO and wild-type mice. Surprisingly, however, while gamma amplitude coupled to theta phase in all recorded regions of wild-type animals, in APP-KO mice theta-gamma coupling was strongly diminished in recordings from the parietal cortex and hippocampus, but not in LFPs recorded from the prefrontal cortex. Thus, lack of APP reduces oscillatory coupling in LFP recordings from specific brain regions, despite not affecting the amplitude of the oscillations. Together, our findings reveal reduced cross-frequency coupling as a functional marker of APP deficiency at the network level.

Difficulties with computational coreference tracking: How to achieve ‘coherence in mind’ without a mind? (2015)

The introduction and maintenance of reference in discourse is subject to a number of language-universal constraints on NP form and selection that allow speakers to maintain reference co-referentially (i.e. from mention to mention) with minimal processing effort across large spans of discourse. Automated approaches to co-reference resolution (i.e. the successful tracking of discourse referents across texts) use a variety of models to account for how a referent may be tracked co-referentially, yet automated co-reference resolution is still considered an incredibly difficult task for those working in natural language processing and generation, even when using ‘gold-standard’ manually-annotated discourse texts as a source of comparison. Less research has been conducted on the performance of automated co-reference resolution on narrative data, which is rich with multiple referents interacting with each other, with long sequences of continuous and non-continuous reference to be maintained. Five freely-available co-reference resolvers were trialled for accuracy on oral narrative data produced by English native speakers using a picture sequence as an elicitation device. However, accuracy levels of under 50% for each resolver tested suggest large differences between human and computational methods of co-reference resolution. In particular, zero anaphora, NPs with modifiers and errors in coding first-mentioned referents appear particularly problematic. This suggests that automated approaches to coreference resolution need a vast range of lexical knowledge, inferential capabilities based on situational and world knowledge, and the ability to track reference over extended discourse if they are to succeed in modelling human-like coreference resolution
Spherical Tokamak for Material Research (1998)

At present spherical tokamaks are assumed to be prospective candidates for construction of thermonuclear reactors. These machines combine the advantages of spheromaks (compactness) and of tokamaks (improved plasma confinement). Such a combination allows achievement of higher plasma parameters in the presence of relative compactness and low cost of the main machine. Spherical tokamaks are also used for testing power stressed elements of the first wall and divertor under loads approaching those in experimental thermonuclear power reactors.
Genomic and proteomic approaches to vaccine candidate identification for<i>Anaplasma marginale</i> (2006)

Outer membrane protein preparations have been demonstrated to elicit protective immunity for Anaplasma marginale. Attempts to recreate this protective immunity using known surface proteins have been unsuccessful; therefore, novel outer membrane proteins have been searched for using a proteomic/genomic approach. Annotation of the whole genome sequence identified 62 outer membrane protein candidates based on sequence similarity to known surface proteins. In a proteomics approach for the identification of immunostimulatory outer membrane proteins, outer membrane preparations that were separated on 2D gels were used to immunize calves . Antisera from the calves were used to detect immunoreactive proteins, which were then selected and subjected to mass spectrometric analyses. These data were mapped back to the annotated A. marginale genome and have identified several new outer membrane proteins that are vaccine candidates.
Regulation of Cell Adhesion Receptors by Transforming Growth Factor-β (1989)

Cell adhesion to extracellular matrices is mediated by a set of heterodimeric cell surface receptors called integrins that might be the subject of regulation by growth and differentiation factors. We have examined the effect of transforming growth factor-beta 1 (TGF-beta 1) on the expression of the very late antigens or alpha beta 1 group of integrins in human cell lines. The six known members of this family share a common beta 1 subunit but have distinct alpha subunits that confer selective affinity toward type I collagen, fibronectin, laminin, and other as yet unknown cell adhesion proteins. Using a panel of specific antibodies and cDNA probes, we show that in WI-38 lung fibroblasts TGF-beta 1 elevates concomitantly the expression of alpha 1, alpha 2, alpha 3, alpha 5, and beta 1 integrin subunits at the protein and/or mRNA level, their assembly into the corresponding alpha beta 1 complexes, and their exposure on the cell surface. The rate of synthesis of total alpha subunits relative to beta 1 subunit is higher in TGF-beta 1-treated cells than in control cells. The characteristically slow (t1/2 approximately 10 h) rate of beta 1 conversion from precursor form to mature glycoprotein in untreated cells increases markedly (to t1/2 approximately 3 h) in response to TGF-beta 1. The results suggest that in WI-38 fibroblasts the beta 1 subunit is synthesized in excess over alpha subunits, and assembly of beta 1 subunits with rate-limiting alpha subunits is required for transit through the Golgi and exposure of alpha beta 1 complex on the cell surface. TGF-beta 1 does not induce the synthesis of integrin subunits that are not expressed in unstimulated cells, such as alpha 4 and alpha 6 subunits in WI-38 fibroblasts. However, alpha 4 and alpha 6 subunits can be regulated by TGF-beta in those cells that express them. The results suggest that TGF-beta regulates the expression of individual integrin subunits by parallel but independent mechanisms. By modifying the balance of individual alpha beta 1 integrins, TGF-beta 1 might modulate those aspects of cell migration, positioning, and development that are guided by adhesion to extracellular matrices.
