A method of preparing an aesculin sturgeon skin gelatin with antioxidant activity and Enterococcus faecalis detection ability includes: 1) mixing a sturgeon skin gelatin and distilled water in a ratio of 1:15-1:25 (w/v) at 50-70° C. and filtering to obtain a sturgeon skin gelatin solution; 2) adding aesculin and a glycerin solution to the sturgeon skin gelatin solution, stirring the resulted sturgeon skin gelatin solution at 30-50° C. for 30 minutes, and filtering; and 3) removing air bubbles from the sturgeon skin gelatin solution of step 2) under reduced pressure, placing the sturgeon skin gelatin solution on an acrylic glass, and drying the sturgeon skin gelatin solution at in a vented oven 25° C. and 45-55% relative humidity for 24 hours to obtain the aesculin sturgeon skin gelatin film.
摘要:
The invention relates to a solid fuel decoupled fluidized bed gasifying method and a gasifying apparatus. By physically separately performing drying and pyrolyzing of fuel, gasification of char, and tar/hydrocarbon reforming, the interactions between the separated chemical reactions and physical processes during fluidized bed gasification can be utilized. Specifically, in a fluidized bed reactor having two reaction chambers, drying and pyrolyzing of fuel, gasification of char, and tar/hydrocarbon reforming are performed, respectively, the reforming of tar/hydrocarbon is promoted through the catalytic effect of the char, and the evaporated fuel moisture is provided to the char gasification and tar/hydrocarbon reforming as an effective reaction agent. Accordingly, the tar content in product gas can be reduced, the use amount of external steam can be reduced, the overall efficiency of gasification can be improved, and this technique can also be applied to the processing of high water-containing fuel. This gasifying method not only can be applied to individual fluidized bed gasification, but can contribute to the design of a combustor that combusts unreacted char, and to advanced decoupled fluidized bed gasification.
摘要:
In the present technique, a dispatch call setup determines (508) whether an auto-reply as a response to a polite dispatch call request is available. If so, a dispatch call blocked using the available auto-reply is sent (512) as a response to the polite dispatch call request. In response to an impolite dispatch call request being received (504, 506), a determination (528) occurs regarding whether an impolite request is allowed, and if not, the impolite dispatch call request is rejected (522). Otherwise, a dispatch call page is sent (534) to indicate the impolite dispatch call request.

摘要:
The present invention provides smell tests (odor identification tests) that are shorter that UPSIT, yet has a statistical sensitivity and specificity equivalent to or better than UPSIT. The odor identification tests of the invention are based on a core set of six odorants, where the six odorants can be selected from the following group of odorants: menthol, clove, leather, strawberry, lilac, pineapple, smoke, soap, natural gas and lemon. The present invention provides odor identification tests that can: (1) discriminate between subjects who are normal and who have a neuropsychiatric condition, cognitive disease or disorder, and/or (2) predict which subjects with mild cognitive disorders will develop various neuropsychiatric conditions or cognitive diseases and disorders. In one embodiment, the test and methods of the invention can provide an early prediction or diagnosis of Alzheimer's disease that is important for patients (including patients who have mild cognitive disorders, such as MCI) and clinicians to make plans for the future and to institute early treatment.

The present invention provides methods for treating ischemic cardiomyopathy. In one embodiment, provided is a method of treating a disease characterized as ischemic cardiomyopathy, comprising administering to a subject suffering from said disease a pharmaceutical composition comprising therapeutically effective amount of synthesized Leonurine. The method induces at least one biochemical change to improve hypoxia myocardial cells survive rate, reduce LDH releasing from the ischemic myocardial cells, and reduce infarction area of cardiomyopathy in the subject.
