A process is described for monitoring the effectiveness of a purification process in removing plasminogen activator (PA) endogenous to Chinese hamster ovary (CHO) cells from a sample containing human tPA or variants thereof. This process comprises incubating the sample with a protease capable of specifically cleaving the Arg Ă¢Ile bond of human wild-type tPA and then with denaturing/reducing agents in respective amounts effective to reduce the disulfide bonds of human wild-type tPA; subjecting the sample to a reversed-phase high-performance liquid chromatography step, and analyzing the elution profile from the chromatography step for the amount of PA endogenous to the CHO cells present therein.

Compounds are provided that act as potent antagonists of the CCR1 receptor, and have in vivo anti-inflammatory activity. The compounds are generally aryl piperazine derivatives and are useful in pharmaceutical compositions, methods for the treatment of CCR1-mediated diseases, and as controls in assays for the identification of competitive CCR1 antagonists.

Abstract:
A method and apparatus for the evaluation and improvement of the mechanical and thermal properties of carbon-nanotube (CNT) and carbon nanofiber (CNF) arrays grown on a substrate is disclosed. The Young's modulus of a CNT/CNF material is measured by applying an axial compressive force on the CNT/CNF array and measuring the applied forces and the induced displacements. Also disclosed are the evaluation of the nonlinear stress-strain relationship of the CNT/CNF material, increasing of the Young's modulus and decreasing the thermal resistance by application of a compressive load, the application of rapid thermal annealing to improve the quality of the CNT/CNF material and to reduce the interfacial thermal resistance, improvement of the bonding strength of the CNT/CNF array to a substrate, evaluation of the bonding strength of the CNT/CNF array to a substrate, evaluation of the shearing force at failure, and an analytical stress model that enables one to predict the interfacial shearing stress from the measured force.

Abstract:
Ophthalmically acceptably wettable silicone hydrogel contact lenses are described. The lenses are derived from a polymerizable composition including a first siloxane monomer. The lenses have ophthalmically acceptably wettable lens surfaces when fully hydrated. Batches of silicone hydrogel contact lenses and methods of making silicone hydrogel contact lenses are also described.
