The latter parameters are particularly important for advanced genetic modification technologies such as gene targeting, where transfected cells need to undergo homologous recombination, clonal selection and proliferation up to a scale that provides a sufficient number of cells for recombination analysis, cryopreservation and subsequent SCNT experiments.
Recently, invented genome modification technologies, such as ZFN (Zinc Finger Nuclease), TALEN (Transcription Activator-Like Effector Nuclease), and CRISPR/Cas9 nuclease (Clustered Regularly Interspaced Short Palindromic Repeats/Cas9 nuclease) can initiate genome editing easily, precisely and with no limitations by organism.
In addition, various modifications and hybrid technologies, such as plasma-assisted electrophoretic deposition (Nie et al. 2001) and a combination of micro-arc oxidation with electrophoresis (Nie et al. 2000) have been developed as well.
Typical risks with high ambiguity are biological hazards such as viruses and bacteria, medical practices such as therapeutic cloning, agricultural technologies such as genetic modification, and the deregulation of financial markets.
In future the use of new technologies, such as genetic modification, can be expected.
The conventional meat industry can also benefit from assimilating biotechnologies such as cloning and genetic modification technologies, using the technology to adapt to the changing environment and respond to the increasing competition from artificial meats.
A crucial step employing domestic animals in biomedicine is genetic modification which requires extensive embryo and embryo-related technologies, such as in vitro production of embryos for stem cell derivation and somatic nuclear transfer cloning.
Making greater use of service-life extension programs, modifications to existing weapons, and inexpensive but high-performance modern technologies such as advanced munitions and robotics can keep a check on cost growth.
They are based on modifications of standard therapies (such as enhancement of instrument tip designs), on development of new technologies (such as lasers), or development of alternative treatment protocols (eg, full-mouth disinfection).
Recent advances in high-throughput technologies such as ChIP-seq [ 2] make the genome-wide profiling of proteins binding or histone modification an easy task.
Many modified technologies such as alkylation, esterification, amidination, deamidination, covalent attachment of carbohydrates and fatty acids, thiol-disulfide exchange, and enzymatic modification can effectively improve the functional properties of proteins [ 1].
