Conclusions The up-regulation of expression of both TNF-α mRNA and IL-1β mRNA was much earlier than that of the expression of IL-1ra mRNA, suggesting that there was an imbalance of inflammatory and anti-inflammatory mediators in the early phase of ALI.
Methods: Inflammatory mediators including IL-1β, IL-6, IL-8, TNF-α,and LTB_4 were measured,which were released from polymorphonuclear (PMN) cells collected from normal subjects and pretreated by homoeriodictyol-7-O-β-D-glycoside with PAF stimulating.
Production medium was optimized for antibiotic production.
We consider a nonlinear parabolic system describing compressible miscible displacement in a porous medium .
The objective of this paper is to deal with a kind of fuzzy linear programming problem based on interval-valued fuzzy sets (IVFLP) through the medium of procedure that turns IVFLP into parametric linear programming via the mathematical programming.
The conclusion that the equilibrium is the continuous function of the dilution rate and substrate concentration in medium in a certain range is concluded.
Many food algae and red tide algae were cultivated in the f/2 medium, and the nitric oxide (NO) concentration of the medium and the cell density were determined.
Because of the existence of nanopores, the dielectric constant of PI films decreased by a wide margin and was less than 2.0 at a PU mass fraction of 20%.
It implies that this is an effective means to reduce the dielectric constant of PI, but it also causes the decrease of tensile strength and the rise of water absorption.
Lead zirconium titanate (PZT) films (Zr/Ti=45:55) with a high dielectric constant are prepared successfully on the low-resistance Si substrate in sol-gel dip-coating process with PT film used as the buffer layer.
The dielectric and ferroelectric properties of the films as well as the relationship between crystallization and preparing condition are studied.
The relative dielectric constant εr and the dissipation factor tgδ of the PZT thin films were measured with an LCR meter and were found to be 158 and 0.04-0.005, respectively.
