The misfolding of islet amyloid polypeptide (IAPP, amylin) results in the formation of islet amyloid, which is one of the most common pathological features of type 2 diabetes (T2D). Amylin, a 37-amino-acid peptide co-secreted with insulin and apolipoprotein E (ApoE) from the beta-cells of pancreatic islets, is thought to be responsible for the reduced mass(More)
During Rhizopus oryzae-mediated methanolysis of triglycerides for biodiesel production, the amount of 1,2-DG and 2-MG as well as the ratio of 1,2-DG/1,3-DG and 2-MG/1-MG differed significantly in different reaction medium, which indicated that solvent might be a crucial factor that would influence the acyl migration rate, leading to varied biodiesel yield.(More)
Blocking the interaction between the E4 isoform of apolipoprotein E (ApoE) and amyloid beta-peptide (Aβ) may be an avenue for pharmacological intervention in Alzheimer's disease (AD). The main regions of interaction of the two proteins are, respectively, ApoE244-272 and Aβ12-28. These protein segments are too large to facilitate the design of small molecule(More)
In order to solve the feeble adaptability and the imbalance between random search and local search in the job-shop scheduling problem, a new adaptive genetic algorithm (AGA) was presented in this paper. The superiority of this algorithm was the adaptation achieved by adjusting the crossover rate and mutation rate. At the same time, the search property has(More)
This paper intends to propose an advanced clustering method, ant colony ISODATA algorithm (ACIA) in real time computer simulation. Ant colony algorithm is used as the method of cursory clustering based on ants piling up their corpses and classifying their young ones. ISODATA algorithm is applied to meticulous clustering. This algorithm has been implemented(More)
An infrared alcohol testing system based on differential absorption is presented. The technique relies on the fact that the breath alcohol gas has a unique, well-defined absorption characteristic within the infrared region of electromagnetic spectrum. It is used to detect the present and concentration of alcohol gas. The non-dispersive infrared gas(More)
To help students handle the diversified routine information, a design proposal and its implementation methods for the students' PDA system have been provided based on Windows Mobile application platform. This proposed system employs Visual Studio 2005 as its development tool and is simulated in actual mobile equipment. The result proves to be desirable.
