  • Publication number: 20240150423
    Abstract: Applications of different configurations of novel glucagon peptide 1 with fatty acid modification or nonmodification in the treatment of T2D or the pancreas protection are provided. The dimer of the present disclosure is formed by two identical cysteine-containing GLP-1 monomers through a disulfide bond. The H-like GLP-1 homodimer (disulfide bond is inside chains) showed remarkable increase in hypoglycemic duration without reducing specific activity. The GLP-1 dimer provided has an in-vivo effective duration of up to 19 days, which significantly prolonged compared with that of the positive control drug Liraglutide with 3 days of effective duration, or thereby greatly promoting the technical advancement in long-acting GLP-1 drugs and facilitating their clinical applications and business. Meanwhile the U-like homodimer (disulfide bond is at the C-terminus) does not affect blood glucose, but can obviously protect pancreatic exocrine cells such as acini and ducts, and improve pancreas function.

  • Publication number: 20140213731
    Abstract: A supercritical carbon dioxide-assisted solid-phase grafting modification method for polypropylene, comprises swelling polypropylene for 0.5 to 10 hours in supercritical carbon dioxide having dissolved vinyl monomer and an initiator, then slowly relieving the pressure; moving the polypropylene that has undergone the swelling process into a reaction kettle, and adding xylene as an interface agent, the mass of xylene being 1% of the polypropylene; increasing the temperature to between 65° C. and 165° C. under normal pressure, and reacting 1 to 10 hours to obtain modified polypropylene; the swelling permeation temperature during the swelling process is from 31° C. to 60° C., the swelling pressure is from 7.5 to 12 MPa; the initiator is an azo compound or a peroxide. In the present method, the grafting rate reaches 5.4%, the thermal property, polarity, and mechanical property all improve substantially, and hydrophilic property is substantially enhanced.

  • Patent number: 8709209
    Abstract: The invention is directed to methods and compositions for reducing the deposition of pitches and stickies in a papermaking process. The method involves introducing an anionic glycerol-based polymer to the papermaking process. This anionic polymer prevents the pitches and stickies from depositing and agglomerating in papermaking processes.

  • Patent number: 8585992
    Abstract: The invention is directed towards methods and compositions for treating slurry to better dewater alumina trihydrate precipitated from the Bayer process. The method comprises using a product comprising the combination of at least two surfactants together with an optional coupling agent to treat the alkaline slurry with certain amount of alumina trihydrate present. Synergistic effects between binary combinations of nonionic and anionic surfactants result in more efficient dewatering aids for alumina trihydrate slurry when combinations of such surfactants are applied. A coupling agent may be used in formulations to reduce viscosity of such surfactant combinations, allowing the practical application of such products.
