8. The significance of the model was indicated by the ANOVA
and the residual analysis. Poly (ethylene oxide) amount, ethylcellulose amount and drug solubility had significant effect on the T90 values whereas poly (ethylene oxide) amount and ethylcellulose amount had significant effect on the n value.”
“A novel copolymer network was prepared using divinyl ether bis[4-(vinyloxy)butyl] (4-methyl-1,3-phenylene) biscarbamate (BECT) as crosslinking agent. First, the backbone chains were synthesized by the copolymerization of acrylic acid (AA) and GSK2879552 in vitro methyl methacrylate (MMA) using reversible addition-fragmentation chain-transfer technique. The molecular weight of poly(AA-co-MMA) was well-controlled, and the polydispersity SNS-032 Cell Cycle inhibitor was low. Carboxyl group on the poly(AA-co-MMA) chains then reacted with BECT in the presence of pyridinium p-toluenesulfonate, generating a copolymer network with hemiacetal component
in the crosslinking segment. After being treated in strong acid, this copolymer network was able to be degraded owing to the hemiacetal structure, but the backbone chains remained intact. The copolymer network was stable in basic or neutral environment. (c) 2011 Wiley Periodicals, Inc. J Appl Polym Sci 121: 1860-1865, 2011″
“Diabetes mellitus is associated with decreased haemodynamic stability and reduced tolerance to hypovolaemia. Compensatory haemodynamic responses during experimental hypovolaemia in type I diabetes patients with (DMR+) and without (DMR-) retinopathy as well as healthy controls (C) were studied. Lower body negative pressure created hypovolaemic circulatory stress. Volumetric techniques were used to assess the compensatory capacitance response (redistribution of peripheral venous blood to the central circulation) and to assess capillary fluid absorption from tissue to blood. The compensatory capacitance response was 1/3 lower in DMR+ compared with C (p = 0.002) and DMR- (p = 0.01). Net capillary fluid absorption was reduced by one-third in DMR- and DMR+ compared BIBF 1120 nmr with C (each p < 0.05). Type I diabetes patients with retinopathy demonstrate
reduced mobilisation of peripheral venous blood to the central circulation. Furthermore, type I diabetes patients present with impaired capillary fluid absorption, which in combination with potentially decreased sympathetic vasoconstriction impedes cardiovascular homeostasis during acute hypovolaemic stress.”
“The aim of this study was to evaluate the effects of preparation method and the type of surfactant on the properties of cephalexin (CPX) microspheres in order to obtain delivery systems suitable for the treatment of dairy mastitis. Microspheres were obtained using various preparation conditions and their physicochemical characteristics such as size, loading efficiency, morphology, and drug crystallinity were investigated.
