2. The aggregation of PS4-&-PEO227-&-PS4 triblock copolymer (the subscripts represent the degree of polymerization) in aqueous solution was investigated by 'H NMR, Fluorescence Probe, and TEM techniques.
After treating with captopril (1mg/kg),the platelet aggregation was significantly lowered(P<0.01). Inhibitingrates of the platelet were AGG(1)58.44 per cent,AGG(5)68.23 per cent aftertakeingdrug 30 minutes and were AGG(1)76.49 per cent,AGG(5) 97.56 per cent after60 miuntes.
The changes of the platelet aggregation and plasma 6-keto-PGF_1α and thromboxane B_2(TXB_2) which were stable metabolites of PGI_2 and TXA_2 respectively were observed in the blood of coronary sinus and artery following acute myocardial infarction in rabbits with or without trichosanthes or/and propranolol treatment.
Results Compared to the control group,at 2 and 24 h,platelet aggregation,TXA_(2),ET were significantly higher,and 6-Keto-PGF_(1a) were significantly lower(P<0.01),and there were severe ischemic injury in the model group;
Compared with LPS group, PCA can significantly increase platelet aggregation and curtail PT(P<0.01),and the statistical differences are not significant(P>0.05)compared with NC group. the group with PCA’s clinical symptoms of rat significantly decrease.
Moreover, azo chromophores show less H-aggregation when the multilayers are fabricated from DMF/H2O mixtures with higher DMF contents.
Furthermore, the dissipative particle dynamics (DPD) was adopted to simulate the aggregation of CTAB in water and ethanol/water mixtures, and the energy difference was calculated for the surfactant tail groups after mixing with the solvent.
It was shown that the crystallization of PCL in thin films is a diffusion-controlled process, and it can be explained by diffusion-limited aggregation.
A distributed routing algorithm for data aggregation in wireless sensor networks
Considering the impact of aggregation cost on the performance of aggregation routes in wireless sensor networks, an aggregation-decision-based distributed routing algorithm for data aggregation is proposed.
