Abstract: A process for the preparation of 2(S)-alkyl-5-halogenpent-4-ene carboxylic esters by enzymatic hydrolysis, comprising the steps: a) enzymatic hydrolysis of racemic 2-alkyl-5-halogenpent-4-ene carboxylic esters in aqueous and alkaline medium in the presence of an esterase; b) isolation of 2(S)-alkyl-5-halogenpent-4-ene carboxylic esters by extraction with an organic solvent; c) isolation of 2(R)-alkyl-5-halogenpent-4-ene carboxylic acids from the aqueous-alkaline medium; d) Esterification of 2(R)-alkyl-5-halogenpent-4-ene carboxylic acids, e) subsequent racemization to form 2-alkyl-5-halogenpent-4-ene carboxylic esters; and f) return of the racemate obtained in step e) to step a), if necessary together with fresh racemic 2-alkyl-5-halogenpent-4-ene carboxylic esters. The process permits the undesired R-stereoisomers to be converted into the desired 2(S)-alkyl-5-halogenpent-4-ene carboxylic esters to avoid waste product from the synthesis.

Abstract: L'invention concerne un élément d'emballage présentant une structure composite. Ces composants renferment une portion de fermeture hermétique pour minimiser l'extrusion. Ledit élément est maintenu sous tension, lorsqu'il est amené pour minimiser les dégâts. Dans un mode de réalisation préféré, un manchon escamotable transfère la force de fixation appliquée à une extrémité à l'extrémité opposée, de manière à éviter le problème d'entassement de l'élément adjacent à l'endroit où il est comprimé, ce qui pourrait sinon déboucher sur une pression de contact de scellement faible insuffisante dans des zones éloignées de l'endroit où la force de compression est appliquée.

Abstract: One embodiment of the present disclosure describes a test assembly including an inflatable packer. An internal control sleeve controls flow of drilling fluid through an inflation port to inflate and deflate the packer. A shifting tool run on a slick line moves the sleeve. The packer has one end attached to an external sliding sleeve which moves upon packer inflation to expose a formation fluid port through which formation testing is performed. After testing and packer deflation, a circulation port may be opened to recover produced fluids up the drill string. A second sleeve controls flow through the circulation port and is controlled by a second shifting tool run on slick line. Other embodiments include a circulation assembly with a sliding sleeve opened and closed by one shifting tool to control circulation and the sliding sleeve itself and its operation.

Abstract: Il s'agit d'un leurre de pêche dont une partie forme une dépression et peut recevoir un mécanisme produisant un cliquetis. Le mécanisme comprend une capsule contenant au moins deux petites pièces dont la courbure minimale est supérieure à la courbure maximale de la capsule, ce qui leur permet de se déplacer librement à l'intérieur de la capsule. La capsule est donc exempte d'angles ou de parties ayant une courbure accentuée et risquant de coincer les pièces mobiles, interrompant ainsi le cliquetis. Le mécanisme est installé sur la portion de réception, comme dans la dépression. Lorsque le leurre se déplace dans l'eau, le mécanisme produit un bruit, au moins de façon sporadique, et ce, quelles que soient la vitesse et la trajectoire du leurre dans l'eau.

Title: Well treating process and system

Granted: 2011-06-07
Abstract: A method for the treatment of a subterranean formation penetrated by a well in which, first and second flow paths are established from the wellhead into the vicinity of the formation. A plugging fluid comprising a suspension of a particulate plugging agent in a carrier liquid is circulated into the first flow path and into contact with the wall of the well within the subterranean formation. The carrier liquid is separated from the particulate plugging agent by circulating the carrier liquid through a set of openings leading to the second flow path, which are dimensioned to allow the passage of the carrier liquid while retaining the particulate plugging agent in contact with the set of openings. The circulation of the plugging fluid continues until the particulate plugging agent accumulates to form a bridge packing within the well. Subsequent to establishing the bridge packing, a treating fluid is introduced into the well through the first flow path and in contact with the surface of the formation in the well adjacent to the bridge packing. The treating fluid may be a fracturing fluid under or an acidizing fluid. A clean-up fluid is circulated into the second flow path to remove the bridge packing.

Abstract: Methods are provided for the synthesis of polymer conjugates of cytokines and receptor-binding antagonists thereof, especially a non glycosylated interferon-beta, which conjugates retain unusually high biological potency. Preparation of polymer conjugates according to the methods of the present invention diminishes or avoids steric inhibition of receptor-ligand interactions that commonly results from the attachment of polymers to receptor-binding regions of cytokines, as well as to agonistic and antagonistic analogs thereof. The invention also provides conjugates and compositions produced by such methods. The conjugates of the present invention retain a high level of biological potency compared to those produced by traditional polymer coupling methods that are not targeted to avoid receptor-binding domains of cytokines. In assays in vitro, the biological potency of the conjugates of non-glycosylated interferon-beta of the present invention is substantially higher than that of unconjugated interferon-beta and is similar to that of interferon-beta-1a that is glycosylated. The conjugates of the present invention also exhibit an extended half-life in vivo compared to the corresponding unconjugated cytokine. The present invention also provides kits comprising such conjugates and/or compositions, and methods of use of such conjugates and compositions in a variety of diagnostic, prophylactic, therapeutic and bioprocessing applications, including treatment of multiple sclerosis.
