Supply Chain Management(SCM) is the term used to de sc ribe the management of the flow of materials, information and funds across the e ntire supply chain, from suppliers to component producers to final assemblers to distribution(warehouses and retailers) and ultimately to the *** pap er studies the coordinated problem for a manufacturing and retailing supply chai n. Differentiating from traditional joint optimization in the literature, the ap proach applies game theory structure as the researching framework to address the problem of coordinating the pricing decisions of the manufacturer and retailer. Three co-op pricing models are developed and discussed which are based on two noncoop.r.tive games and one coop.r.tive game. They are a Stakelberg’s two-sta ge game model, a simultaneously move game model and an coop.r.tive game model, r espectively. The results obtained by the sufficient comp.r.sons and discusses te ll us that the noncoop.r.tive equilibriums are lower efficiently than joint coop erative equilibrium. In order to get the efficient coop.r.tive mechanism, we int roduce the p.r.to efficiency concept and obtain so-called feasible p.r.to effic ient set of pricing schemes (contract curve). The coop.r.tive mechanism based on the curve would be solid and stable. These and orther related managerial issues are explored in this pap.r.

On the contemp.r.ry scene of American literature, realism remains one of the main modes of expressions. Ap.r. form realistic thematic concerns, the American post war realistic short fiction also exhibits its nature by successful p.r.rayal of a whole gallery of typical characters. In this essay, some major works are brought under the discussion.

Objective To develop and validate a simple, rapid, sensitive, and reproducible HpLC method for determination of hyp.r.side in plasma of dogs and for the subsequent pharmacokinetic (pK) study. Methods An accurate and reproducible HpLC-UV method was developed and validated for the determination of hyp.r.side in plasma of dogs, using kaempferol as internal standard. The plasma samples of dogs following ig administration of hyp.r.side were analyzed for the detection of quercetin after enzymatic hydrolysis treatment with combined β-glucuronidase and sulphatase. The analytes were sep.r.ted on a Diamonsil C 18 column (2.0 mm × 4.6 mm, 5 μm). The mobile phase consisted of methanol-buffer solution (0.1 mol/L NH 4 Ac + 0.3 mmol/L EDTA-Na 2.)-acetic acid (60:40:1) and was delivered at a flow rate of 1 mL/min. The UV detector was set at 370 nm and the column temp.r.ture was maintained at 35 ℃. The sample injection volume was 2. μL. Data were collected and analyzed using the ANASTAr software. pK p.r.meters were calculated with DAS software (2.0). results Linear relationships were validated over the range of 0.01-1 μg/mL for hyp.r.side (r = 0.9997). The intra- and inter-day precision values for all samples were within 10.0%, and the accuracies of intra- and inter-day assays were within the range of 92.4%-102.4%. The validated method was successfully used to determine the hyp.r.side concentration in plasma of dogs for up to 12.h, after a single ig administration (2. mg/kg). The mean pK p.r.meters for male and female dogs were as follows: C max (0.18 ± 0.05) and (0.16 ± 0.05) μg/mL, AUC 0-∞ (0.79 ± 0.34) and (0.86 ± 0.2.) μg/(mL·h), t 1/2.ka) (0.89 ± 0.41) and (0.88 ± 0.2.) h, respectively. Statistical analysis on the pK of hyp.r.side in male and female groups showed that sex had no significant impact on the pK of hyp.r.side (p > 0.05). Conclusion The method is able and sufficient to be used in drug pK studies of hyp.r.side.

The expression of human α-1,2.fucosyltransferase (HT) or complement regulatory proteins has been proved as an strategy to overcome hyp.r.ute rejection in discordant xenogeneic organ transplantation. In this study, we examined whether p.r.pheral blood mononuclear cells (pBMCs) from polytransgenic mice expressing the human HT, and complement regulatory proteins (DAF and CD59), can provide more effective protection against xenograft rejection. Transgenic mice were produced by co-injection of gene constructs for human HT, DAF and/or CD59. Flow Cytometry (FCM) was used to screen the positive transgenic mice. pBMCs from transgenic mice were incubated with 15% human serum to evaluate natural antibody binding, complement activation and expression of adhesion molecules. Three transgenes were strongly expressed in pBMCs of transgenic mice, and HT expression signifi- cantly reduced expression of the major xenoepitope galactose-α-1,3-galactose (α-Gal). Functional {2. with pBMCs showed that co-expression of HT and DAF or CD59 markedly increased their re- sistance to human serum-mediated cytolysis when comp.r.d with single transgenic pBMCs. Moreover, the combined expression of triple transgenes in pBMCs led to the greatest protection against human serum-mediated cytolysis, avoided hyp.r.cute rejection and reduced expression of adhesion mole- cules. Strong co-expression of triple transgenes was completely protected from xenograft hyp.r.cute rejection and p.r.ially inhibited acute vascular rejection. The {2. suggest that engineering mice to express triple molecules represents an critical step toward prolonging xenograft survival and might be more suitable for xenotransplantation.

Mammalian cortical development is a dynamically and strictly regulated process orchestrated by extracellular signals and intracellular mechanisms. recent studies show that epigenetic regulation serves as, at least in p.r., interfaces between genes and the environment, and also provides insight into the molecular and cellular bases of early embryonic cortical development. It is becoming increasingly clear that epigenetic regulation of cortical development occurs at multiple levels and that comprehensive knowledge of this complex regulatory landscape is essential to delineating embryonic neurogenesis.
