Physico-chimie des lipopolysaccharides et réponse inflammatoire : rôle des lipoprotéines

2014

LPS is a potent bacterial pro-inflammatory agent, consisting of hydrophilic, polysaccharide part and of a lipid A which is considered like active moiety. Nevertheless, the O chain of LPS influences their aggregation in aqueous media. Therefore, our goal has been to determine the role of O chain on the LPS biological and physiopathological effects. Our work was organized according to three main axes, and led to the following findings :- development of a new LPS assay by LC-MS/MS. The combination of this new technique with LAL test allowed us to calculate an inactivation ratio which reflects the ability of host organism to inactivate LPS, especially through their transfer to HDL by PLTP. The …

Decomposition studies of group 6 hexacarbonyl complexes. Part 1: Production and decomposition of Mo(CO)6 and W(CO)6

2015

Abstract Chemical studies of superheavy elements require fast and efficient techniques, due to short half-lives and low production rates of the investigated nuclides. Here, we advocate for using a tubular flow reactor for assessing the thermal stability of the Sg carbonyl complex – Sg(CO)6. The experimental setup was tested with Mo and W carbonyl complexes, as their properties are established and supported by theoretical predictions. The suggested approach proved to be effective in discriminating between the thermal stabilities of Mo(CO)6 and W(CO)6. Therefore, an experimental verification of the predicted Sg–CO bond dissociation energy seems to be feasible by applying this technique. By in…

A novel target of lithium therapy.

2000

Phosphatases converting 3'-phosphoadenosine 5'-phosphate (PAP) into adenosine 5'-phosphate are of fundamental importance in living cells as the accumulation of PAP is toxic to several cellular systems. These enzymes are lithium-sensitive and we have characterized a human PAP phosphatase as a potential target of lithium therapy. A cDNA encoding a human enzyme was identified by data base screening, expressed in Escherichia coli and the 33 kDa protein purified to homogeneity. The enzyme exhibits high affinity for PAP (K(m)1 microM) and is sensitive to subtherapeutic concentrations of lithium (IC(50)=0.3 mM). The human enzyme also hydrolyzes inositol-1, 4-bisphosphate with high affinity (K(m)=0…

Sobre el orden seguido en el ritual de Cabeço das Fraguas y la naturaleza de las HOSTIAE y VICTIMAE en él ofrecidas y sacrificadas

2018

Este trabajo trata sobre la naturaleza de las víctimas en el ritual indoeuropeo y la estructura sintáctica de la inscripción lusitana de Cabeço das Fraguas (Portugal), proponiendo una nueva lectura de una de las palabras del texto. This paper about the Indo-European ritual sacrifice in lusitanian inscription of Cabeço das Fraguas propose a new reading and interpretation of the text.

Molecular characterization of a male-specific glycosyl hydrolase, Lma-p72, secreted on to the abdominal surface of the Madeira cockroach Leucophaea m…

2003

0264-6021 (Print) Journal Article Research Support, Non-U.S. Gov't; The epicuticular surface protein Lma-p72 is specific to the abdominal secretions of Leucophaea maderae (Madeira cockroach) adult males. Natural Lma-p72 was purified and the complete cDNA sequence determined by reverse-transcription PCR using primers based on Edman degradation fragments. Northern blot and in situ hybridization analyses showed that Lma-p72 was expressed in the tergal and sternal glands. Sequence alignment indicates that Lma-p72 is closely related to the family 1 glycosyl hydrolases (EC 3.2.1). Native Lma-p72 was proved to be active in the abdominal secretions and exhibit a beta-galactosidase-like activity. Ho…

Technique and results of the retroperitoneoscopic adrenalectomy via a lumbar approach

1998

Introduction: Since 1992, endoscopic techniques have been used increasingly in adrenal-gland surgery. In the present paper, the technique of the retroperitoneoscopic adrenalectomy via a lumbar approach is described. Methods: The patient is placed in a lateral decubitus position. In the first step, a dilatation trocar is introduced in the retroperitoneal space to create an artificial cavity. The dilatation trocar is replaced by a blocking trocar to close off the operating field. After insufflation of CO2, two additional trocars are introduced in the area of the conventional flank incision. Adrenalectomy is performed via these ports. Once the adrenal gland is completely mobilized, it is inser…

Primacía epistémica en géneros interaccionales: atenuación, intensificación y territorio

2018

En la última década, ha surgido dentro del Análisis Conversacional una corriente teórica en torno al concepto de primacía epistémica en interacción, dentro de la cual se concibe la transmisión de información como una cuestión de territorio. En este trabajo, se analizan secuencias de aserciónacuerdo en conversaciones y entrevistas con el fin de mostrar que los mecanismos de atenuación e intensificación empleados por los hablantes funcionan como huellas de la interpretación que hacen los interlocutores de la situación en términos de posicionamiento epistémico. Se argumenta que existen casos de congruencia epistémica –cuando los interlocutores convergen en su interpretación de la situación– y …
