摘要:
Described is a method for the preparation of a gelatin hydrolysate having a decreased endotoxin content, comprising the steps of incubating a solution of gelatin of gelatin hydrolysate at a temperature of 70-125° C. at a pH of 3.5 or less for a time period of at least 15 minutes, and recovering the gelatin hydrolysate. Further a gelatin hydrolysate thus obtained is described.

The present disclosure relates to lipoprotein complexes and lipoprotein populations and their use in the treatment and/or prevention of dyslipidemic diseases, disorders, and/or conditions. The disclosure further relates to recombinant expression of apolipoproteins, purification of apolipoproteins, and production of lipoprotein complexes using thermal cycling-based methods.
摘要:
A gelatin or a chemically modified product thereof contains 10 to 50% by mass of a high-molecular weight component, and a low-molecular weight component in such an amount that a value obtained by subtracting a low-molecular weight component content from a high-molecular weight component content is greater than or equal to 0% by mass.

The methods include administering an effective amount of apolipoprotein A-IV to the subject. The pharmaceutical composition includes apolipoprotein A-IV formulated for administration to a subject for the treatment of type two diabetes mellitus. Also disclosed are methods for substantially restoring glucose tolerance in a subject in need thereof to a normal level and methods for lowering blood glucose levels in a subject in need thereof.
摘要:
A light activated collagen-flavin composite layer incorporating riboflavin is applied as treatment for infected lesions. These composites have also been found to be strong tissue adheives that are effective in closing and sealing wounds, fixation of grafts/ implants and anastomoses. Advantages include speed of closure, reduced infection due to the elimination of foreign matter, evidence of accelerated wound healing and the ease of use in complex surgery, especially when watertight seals, limited access or small repair size are important factors. The riboflavin in the collagen layer is exposed to light (e.g., light having a wavelength between 360-375 nm or 440-480 nm), decomposing the riboflavin to form reactive oxygen species (ROS). Strong crosslinks between the collagen composite and tissue results. In addition, similar exposures eradicate pathogens in the wound.
摘要:
This invention relates to the use of a composition comprising a polysaccharide and a botulinum toxin for reducing a skin wrinkle. In some embodiments, the polysaccharide comprises disaccharides. In some embodiments, the average molecular weight of a disaccharide unit of the polysaccharide is between about 345 D and about 1,000 D.
摘要:
Methods are provided for purifying marine collagen and for processing the collagen into porous sponges. Products produced with these methods and the use of the products are also provided.
摘要:
Gelatin is produced by defatting and chopping rind, hydrolysing with acid, neutralising, and extracting with water. By defatting the rind before hydrolysing, the yield of high Bloom gelatin is typically 50% higher than previously. Furthermore, the gelatin thus produced has a higher Bloom strength.
摘要:
A method for producing gelatin peptide comprises the steps of cleaning fish skin with 0.1-5% salt water and fresh water, obtaining an extract from the fish skin using fresh water in neutral pH at 50-100° C., subjecting the water phase to enzymatic digestion, concentrating solution of the digest, activated carbon treatment of the concentrated solution of the digest, and drying the yield. The concentration of salt in the salt water used as cleaning water is preferably 0.5-2%. The fish skin is preferably from white meat fish. The fish skin from pollack such as Alaskan pollack or Pacific cod is particularly preferred. This method enables one to obtain, from fish skin, gelatin peptide from which fish odor is sufficiently eliminated by utilizing simplified processes to be executed under easily adjustable conditions.
