On peut obtenir un bon désencrage des vieux papiers à consistance élevée en commençant par une réduction en pâte à pH élevé, puis en ajoutant de la cellulase alcaline et en laissant la cellulase agir pendant la réduction en pâte et/ou la macération. L'amélioration du désencrage accroît la blancheur et la propreté (moins de particules d'encre) du papier fabriqué à partir de la pâte traitée après séparation des particules d'encre. Ce traitement à la cellulase permet une meilleure utilisation de machines comme les épaississeurs, ainsi qu'un meilleur égouttage de la pâte pendant la fabrication du papier.

Cellules bactériennes portant dans son génome une structure d'ADN intégrée sans réplication, comprenant (1) une séquence d'ADN d'intérêt, (2) une séquence homologue à une région du génome de la cellule et (3) une origine de réplication, ladite structure d'ADN étant dépourvue d'un gène fonctionnel codant pour un facteur requis pour amorcer la réplication à partir de ladite origine de réplication.
摘要:
Heterologous heme proteins may be produced extracellularly in filamentous fungi by transforming a filamentous fungus with a vector comprising a DNA sequence encoding a heterologous heme protein and a DNA sequence encoding a preregion permitting secretion of the expressed heme protein, and culturing the transformed filamentous fungus in a suitable culture medium to produce the heme protein.

La préparation de cellulase décrite, qui sert à réduire l'aspect rèche de tissus contenant du coton et qui sert à réduire la vitesse à laquelle de tels tissus deviennent rèches, comprend au moins 40 % environ d'un composant d'endoglucanase (calculés sur la base de la teneur en protéines totale) présentant une activité d'endoase élevée et une affinité pour la cellulose.
摘要:
A film-forming pharmaceutical composition for dermal application comprises at least one therapeutically active ingredient dissolved in a volatile solvent, the composition further comprising a film-forming polymer, a plasticizer and an oily release-enhancing agent. The composition is capable of forming, after application on skin and evaporation of the solvent, a continuous phase comprising the film-forming polymer and the plasticizer and a dispersed phase comprising droplets of the oily release-enhancing agent.

Compounds according to formula I: in which formula R1 and R2, which may be the same or different, represent halogen, (C1-C6) hydrocarbyl, optionally substituted with one or two hydroxyl group on one or more fluorine atoms, or, together with the carbon atom to which they are both attached, R1 and R2 form a (C3-C6)carbocyclic ring, or one of R1 and R2 taken together with R3 forms a direct bond, such that a triple bond is constituted, or R1 and R2 represent both hydrogen; R3 when not forming a direct bond with one of R1 and R2 represents hydrogen or (C1-C3)hydrocarbyl; X represents (E)-ethylene, (Z)-ethylene, ethynylene, or a bond; Y and Z independently represent hydrogen or methyl; the bond between C#16 and C#17 is depicted with a dotted line to illustrate that said bond may be either a single bond, in which case the projection of the ring substituents is beta, or a double bond; A represents hydroxyl, fluorine or hydrogen; B represents CH2 or H2; the configuration is the 3-position corresponds to the same configuration as in natural vitamine D3 (normal), or the configuration in the configuration in the 3-position is opposite to that of natural vitamin D3(epi); with the proviso that when X represents (E)-ethylene or (Z)-ethylene, one of R1 and R2 taken together with R3 may not form a direct bond, such that a triple bond is constituted; with the further proviso that when X represents a bond R1 ands R2 are nor hydrogen; with the further proviso that the compound of formula I is not 3(S)-hyroxy-9, 10-secocholesta-5(Z),7(E),10(19),22(E),24-penta-ene; and prodrugs and stereo isomeric forms thereof are provided together with their use in therapy, and their use in the manufacture of medicaments.
摘要:
The invention relates to compounds of general formula (I) wherein X, A, R1 and R2 are as defined herein for use as antiinflammatory agents capable of modulating the activity of a protein tyrosine kinase of the Src family.
摘要:
Certain oxindole compounds have been found to be effective in experimentally induced autoimmune encephalitis and are therefore suggested for the preparation of a medicament for the prevention, treatment or amelioration of multiple sclerosis, or to delay the onset of or reduce the relapse rate in multiple sclerosis.
