OBJECTIVE In diabetes, intracellular accumulation of sorbitol resulting from the high extracellular levels of glucose leads to depletion of intracellular compounds including taurine. This is associated with the development of late diabetic complications such as cardiomyopathy. The development of myocyte hypertrophy has been largely attributed to angiotensin(More)
To investigate the effects of leptin on expression of acyl-coenzymeA: cholesterol acyl-transferases-1 (ACAT-1) in monocyte-macrophage differentiation, human monocytic cells (THP-1) were cultured in RPMI 1640 and made to differentiate into macrophages under the incubation with phorbol myristate acetate (PMA) for 48 h. The cells were divided into 4 groups(More)
This study examined the potential roles of astragalus and angiotensin II type 2 receptor (AT2) in rats with streptozotocin (STZ)-induced diabetic cardiomyopathy. Of 52 female 4-week-old Wistar rats treated with high glucose and lipid diet to induce insulin resistance, 7 treated with sodium citrate buffer (pH=4.5) served as controls (con1) and the other 45(More)
This paper fouces on the spectrum handoff in cognitive radio which secondary users(SU) usually use the overlay spectrum acess scenario. We use the fuzzy logic and pridect a reserved channel table, when the spectrum handoff occur, SU can choose the available spetrum access quickly. Because of primary users(PU) appear uncertainty, the correctness of backup(More)
In new-type distributed software environment, the interactive behaviors produced by loosely-coupled software entities behave of emerging, dynamic, accidental, correlative and repeating properties. The paper tries to extract them into definable and relatively stable behavior analysis model between behavior process and corresponding effects. Software(More)
The software is essentially replacing human beings to carry out some certain behavior and software credibility is mainly represented by its credible behavior, so it will be more direct and reliable to assess software credibility according to the information of software runtime behavior. The concept of behavior pattern is abstracted from the software(More)
