41results about How to "Increased fibrillation" patented technology

A process for making fibrillated fibers includes preparing a fluid suspension of fibers, low shear refining the fibers at a first shear rate to create fibrillated fibers having a reduced CSF, and subsequently higher shear refining the fibers at a second shear rate, higher than the first shear rate, to increase the degree of fibrillation of the fibers. The refining at the first shear rate may be with a rotor at a first maximum shear rate and the refining at the second shear rate may be with a rotor at a second maximum shear rate, higher than the first maximum shear rate. The process may further include pre-treating the fibers by high shear refining with impact to stress the fibers prior to low shear refining.

Protection of proteins against fibrillation may be afforded by introduction of certain histidine substitutions into the protein, such that a pair of histidines are present with sufficient spacing as to allow the histidines to coordinate with zinc. In the case of insulin, introduction of histidine residue substitutions at residues A4 and A8 together or a histidine residue substitution at residue B1, provides increased resistance to fibrillation while maintaining at least a majority of the activity of the insulin analogue. Introduction of a histidine residue substitution at residue A8 restores at least a portion of fibrillation resistance that may have been harmed by substitutions present on the B-chain such as those present in fast-acting insulins. Proteins protected by such histidine substitutions may be used to provide a pharmaceutical composition. A method of treating a patient includes administering a physiologically effective amount of the pharmaceutical composition to the patient.

The invention relates to the technical field of tobacco sheet production, in particular to a pulping abrasive disc designing method. The method comprises the main steps that in a pulping region and apre-pulping region, two concentric arcs with one tooth width interval are used for determining the position of one grinding tooth, on the basis, a plurality of grinding teeth are evenly arrayed aroundthe center of an annular fluted disc in the pulping region and the pre-pulping region, and one tooth groove with the width becoming larger gradually from interior to exterior is formed in the interval between every two adjacent grinding teeth; in a scattering region, one radius of the annular fluted disc rotates around the focal point on the outer edge of the scattering region to obtain a straight line, a column of grinding teeth are arranged along the straight line at the equal intervals of one tooth width, and on the basis, a plurality of columns of grinding teeth are evenly arranged aroundthe center of the annular fluted disc at the scattering region. Accordingly, a pulping abrasive disc is obtained, and the method has the advantages of being simple, feasible and accurate in design. The pulping fluted disc obtained through the designing method can reduce cutting and breaking of rod materials and increase the pulping yield.

The present invention is directed to novel pharmaceutical combinations including compositions and kits comprising bretylium as the active ingredient, as well as methods for preventing and / or treating conditions related to the cardiovascular system using such novel pharmaceutical combinations.

The invention discloses a collagen casing having a variety of application characteristics. The collagen casing is prepared by lamelliform and dispergated collagen fibers, a water-soluble collagen, vegetable fibers, a non-collagen type protein and glycerol. During preparation, the water content of the lamelliform and dispergated collagen fibers is adjusted to be 82 to 88% by means of water firstly, and then the lamelliform and dispergated collagen fibers are blended and kneaded with all other raw materials for 4 to 6 hours to obtain a collagen slurry material. After that, the water content of the collagen slurry material is adjusted to be 90 to 95% by means of water, and the pH value of the collagen slurry material is adjusted to be 2.5 to 3.0. Then, the collagen casing is shaped on a casing shaper and the pH value of the collagen casing is adjusted to be 4 to 6. After the drying and cooking process, a collagen casing finished product is finally obtained. According to the technical scheme of the invention, the collagen casing is good in mechanical strength during the casting and cooking process, and can be kinked and segmented at a high speed. During the cooking process, the collagen casing is free from being broken and is still good in chewiness. At the same time, a sausage prepared by the above casing is still kept in good shape and is prevented from being torn down, broken or decorticated during the water-boiling, frying and other high-temperature cooking process before eating.

This invention relates to a modifying method with enzyme method to sulfate wood pulp, in which, enzyme is added into the sulfate wood pulp before beating, the proportion of enzyme and the pulp is 20-1000g / t, the density is 3-15%, temperature: 20-60deg.C, time: 0.5-4h, pH: 5.0-8.5.

The subject matter of this invention is directed towards chemically and thermodynamically stable single-chain insulin (SCI) analogues that are resistant to deamidation and fibrillation. The invention further discloses improved methods for the recombinant expression, purification and refolding of SCI.

The invention discloses a grinding table of a disc grinder for preparing synthetic fiber pulp, which comprises a grinding plate, wherein the working surface of the grinding plate is provided with a plurality of grooves; the grooves are distributed in a multiple-layer concentric circle mode around the grinding plate; the grooves are evenly distributed on each layer of the concentric circle; grinding teeth are formed on the grinding plate between every two adjacent grooves on the same circle; and a pulp baffle plate is formed at the gap between any two adjacent layers. The invention can prolong the the residence time of materials in the disc grinder, weaken the cut-off function of the grinding table, enhance the effects of crushing, kneading and fibrillation on the fibers, and greatly improve the microfibrillation degree of the pulp fibers.
