Design of a capillary viscometer for assay or collagenase activity by "continuous" observation of the hydrolysis of a soluble collagen with a time of flight flowmeter / Samuel M. Mozersky in JOURNAL OF THE AMERICAN LEATHER CHEMISTS ASSOCIATION (JALCA), Vol. LXXXXI, N° 10 (10/1996)

Titre : Design of a capillary viscometer for assay or collagenase activity by "continuous" observation of the hydrolysis of a soluble collagen with a time of flight flowmeter Type de document : texte imprimé Auteurs : Samuel M. Mozersky, Auteur ; David G. Bailey, Auteur Année de publication : 1996 Article en page(s) : p. 263-269 Note générale : Bibliogr. Langues : Américain (ame) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The design of a capillary viscometer for semi automated assay of collagenase activity is described. The rate of flow of a solution of a soluble derivative of collagen undergoing hydrolysis by the collagenase is measured "continuously" by an electronic flow meter. Since the reciprocal of the flow-rate is proportional to the viscosity and the latter is a (double exponential decay) function of the collagenase concentration (as well as of time), collagenase concentration can be determined from the flowrate at a given incubation time. The data are collected automatically, stored in a computer, and analyzed at the analyst's convenience. The viscometer is suitable for use in research laboratories investigating damage to hides (and therefore to leather) caused by bacterial digestion of collagen.

The generation of an in-vitro tissue from bovine fibroblasts is carried out using a scatfold to generate a three-dimensional extra-cellular matrix (3D ECM). The development of a biopelt is by an in-vitro production at lab scale in a bioreactor with specific culturing conditions. New methodologies to stabilize the biomaterial generated were investigated. In particular, the biomaterial was stabilized by immersion in solutions of vegetable tannins and cross-linking agents in an aqueous-solvent medium.

Système de libération contrôlée (technologie)Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : ChlorHexidine Digluconate [CHD] was encapsulated inside an ethylcellulose shell material [Aquacoat ECD], and then spray dried to produce mixed microparticles (MPs). The validity and functional quality of the resultant [CHD-MPs] were analyzed on vamp and lining leather which are used to manufacture shoes for diabetics. The morphology, efficiency of encapsulation and in vitro release characteristics of the [CHD-MPs] were optimized in order to impregnate [CHD-MPs] onto leather footwear for diabetics. Scanning electron microscopy (SEM) was used to characterize the [CHD-MPs] and the leathers treated with it. SEM images illustrated that the [CHD-MPs] were spherical, smooth in shape and adhered well to leather. In vitro CHD-release studies from its MPs, and for leather treated with it were performed in phosphate buffer saline at pH =7.2. There was an inherently controlled release behaviour of CHD for all the formulations on leather. Finally, microbiologic studies on leather treated with [CHD-MPs] were done. This study suggested that footwear containing [CHD- MPs] is/will improve the quality of daily life for diabetics. Note de contenu : - EXPERIMENTAL : Materials

Cot, Auteur ; Albert M. Manich, Auteur ; C. Aramon, Auteur ; M. Baucells, Auteur ; M. Roura, Auteur ; G. Lacort, Auteur Année de publication : 1991 Article en page(s) : p. 114-121 Note générale : Bibliogr. Langues : Anglais (eng) Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : The future of the tanning industry is concerned fundamentally with three areas : (a) raw materials, (b) energy and (c) environment. With regard to raw materials the trend is towards making the fullest possible use of these products, which involves the processing of all by-products of the tanning industry.
In this work a pilot plant for the treatment of the different by-products of the tanning industry has been devised. The essential chemical process is based on the oxidising action by hydrogen peroxide in an alkaline medium of the chrome (III) present in the by-products, which permits the formation of inter and intrafibrilar peroxochromate compounds which have great oxidising capacity. By adjusting the amount of hydroxyl ions in the bath,the amount of hydrogen peroxide and the volume of the bath ; we may obtain either, the total solubilization of the by-products, or a dechroming effect, whilst maintaining the original macromolecular fibrous structure. Furthermore, the chemical process of dechroming is without doubt of great importance due to the overall volume of chromed by-products generated by mechanical operations, such as : splitting, shaving, and trimming are chrome tanned. For this reason, we sought to produce a collagenic material with unchanged physico-chemical characteristics and with a zero chrome level.
To this end, we made an optimization study of the Box-Behnken type to enable us to study the most signficant variables that intervene in this process and, to allow us to obtain the optimum conditions in order to achieve an end product with a zero chrome level. Thus, this represents new openings for the application of chromed by-products in the fields of medicine, food, cosmetics with a substantial increase in the added value of the recovered final product.En ligne : https://drive.google.com/file/d/1_ZqN-yqBr8i5JD2Mgp8k5zaJjeGR5u3Z/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=8682
