The cDNA fragment of human TRAIL (TNF-related apoptosis inducing ligand) was cloned into RevTet-On, a Tetregulated and high-level gene expression system. The gene expression system was constructed in a human leukemic cell line: Jurkat. By using RevTet-On TRAIL gene expression system in Jurkat as a cell model, we studied the influence of TRAIL gene on the changes of cellular apoptosis before and after the TRAIL gene expression, which was induced by adding tetracycline derivative doxycycline (Dox). The results indicated that the cellular apoptosis ratio was largely dependent on the TRAIL gene expression level. Moreover, it was found that the apoptosis-inducing TRAIL could cause significant changes in the biophysical properties of Jurkat cells. The cell surface charge density decreased, the membrane fluidity declined, the elastic coefficients K_I increased, and the proportion of α-helix in membrane protein secondary structure decreased. Thus, the apoptosis-inducing TRAIL gene caused significant changes on

JT SQE system is a software quality and measurement system. Its design was based on the Chinese national standards of software product evaluation and quality characteristics. The JT SQE system consists of two parts. One is the model for software quality measurement, which is of hierarchical structure. The other is the process of requirements definition, measurement and rating. The system is a feasible model for software quality evaluation and measurement, and it has the advantage of a friendly user interface, simple operation, ease of revision and maintenance, and expansible measurements.

4 One Cycle Control of Power Factor Corrected Rectifiers PFC rectifiers serve the same purpose as the APFs do except at lower power levels. Articles [5,6,7,14] have shown numerous three-phase topologies for rectification. Those with a single ca-pacitor output rail are two level converters suitable for low voltage and high current operation while the others with split rails over two capacitors are threelevel converters suitable for high voltage operation.

Owing to the high oxygen-respiration in the brain of mammals, oxidative damage to prion protein hasbeen suggested to be an additional factor. A large body of intriguing features of scrapie and prion diseases haveprovided multiple lines of indirect chemistry evidence, suggesting that the infectious agents may be putative forms ofsequence-specific prion radicals (SSPR) and/or their immediate precursors in the transmissible spongiform encepha-lopathies (TSE). Here a molecular mechanism corresponding to the self-replication of scrapie protein mediated byprion free-radical processes, consonant with "protein-only" hypotheses is proposed. This new theory may not onlyaid our understanding of the occurrence of prions, but also provides new insight into the possible chemistry principlesunderlying the neurodegenerative disorders. It is anticipated that future studies based on this suggestion and chem-istry principles of genetic diseases may allow us to determine an effective approach to stop mad cow disease and itshuman version, new variant of Creutzfeldt-Jakob disease (v CJD).

In prion diseases the irreversible protein structural transformation process is completed in the brains of mammals within a few months, the uniformly generated infectivity displays extraordinary resistance to inactivation, suggesting that a vital energy source is required for the production of infectious particles. Considering the high oxygen-respiration rate in the brains, prion protein oxidative damage can be the crucial factor. Both theoretical consideration of the nature of protein radical reactions and a large body of previously unraveled feature of scrapie and prion diseases have provided multiple distinct lines of compelling evidence which persuasively support a suggestion that the infectious agents may be prion (free) radicals produced from protein oxidative damage. This paper describes that scrapie prions are most likely formed from prion radicals and oxidative species-mediated sequence-specific cross-linking of benign prion proteins.
