At the same time, we should also see that the administration according to law is not perfect, and its shortcomings exist in different degree and need to be further improved. Based on the analysis of the status quo of grass-roots administrative law enforcement in China, this paper tries to put forward corresponding countermeasures, so as to promote the work of law-based administration for the corresponding study.展开更多

Under axial rubbing action, the failure mode of the core yarn is the stripping of the sheath from the core. This paper introduces a method to test the anti - stripping property of the core yarn. With a modified Universal Testing Machine, the stripping resistance of friction spun core yarn can be continuously measured. Some factors Influencing the measurements are discussed in detail. The testing results are compared with those from a Y731 Yarn Abrasion Tester and fur - ther confirmed by weaving practice.展开更多

An edible fruit from traditional medicinal plant Capparis zeylanica (CZ) was studied for its anti diabetic, insulin secretagogue activities and mechanisms involved in it. In Streptozotocin induced diabetes rats, oral administration of Capparis zeylanica methanolic extract (CZME) (200 mg/kg body weight) for 28 days showed a significant reduction in blood glucose levels by 35.53% and enhanced circulating insulin levels by 81.82% than the diabetic control rats. The insulin secretagogue activity mechanisms of the extract were evaluated by using mouse insulinoma beta cell line (MIN6-β). The extract stimulated insulin release in dependent manner of glucose concentration (3 - 16.7 mM) and extract dose (5 - 500 μg/mL). The insulin releasing effect of the extract was significantly enhanced by 3-isobutyl-1-methyl xanthine, glibenclamide, elevated extracellular calcium and K+ depolarized media. This insulin release was significantly reduced in calcium blocking conditions (by nifedipine and EGTA), in the presence of potassium channel opener (diazoxide). Hence, anti diabetic activity of CZME might be a result of its stimulatory effect on insulin release from pancreatic beta cells via KATP channel dependent and independent ways. These results indicate that CZ fruits have the potential to use in diabetes therapy.展开更多
