One of the latest and most controversial areas of science is biotechnology. Genetic engineering concerns with the manipulation of DNA molecules to modify plants, animals and other creatures. Scientists are now able to isolate a gene or genome in an animal or plant to another one, based on the traits they want to transfer. The movement of a gene from a living creature to another one is called th...

synthesized from Takara Biotechnology Co. Ltd. (Dalian, China). Recombinant human PDGF-BB and PDGF-AB were purchased from Bowling Vaccine & Pharmaceutical Inc. (San Francisco, CA). Bovine serum albumin (BSA), human serum albumin (HSA), human immunoglobulin G (IgG), thrombin, bovine serum were obtained from Dingguo Biotechnology Co. Ltd. (Beijing, China). Escherichia coli Exonuclease I (Exo I) w...

Construction of spherical liposomes is critical for developing tools for targeted gene and drug delivery applications in biotechnology and medicine, however, it has been demonstrated only in solution phase until now. Spherical liposome tethering on pristine thiol monolayer on gold transducer and its application to label free DNA sensing and transfection has rarely been reported. Here, we report...

The encapsulation of individual nanoparticles has gained great attention as a method for both stabilizing nanoparticles and tailoring their surface properties. In particular, the encapsulation of nanoparticles with silica shells is advantageous for bioconjugation and applications to (nano)biotechnology. Herein we report a method for constructing gold nanoparticle (AuNP)/silica core/shell hybrid...

Our comments on this CBAC interim report are based on nearly 20 years of research on biotechnology. The Canadian Institute for Environmental Law and Policy (CIELAP) first began investigating biotechnology regulation in 1984, when we organized the first conference in Canada on environmental issues regarding biotechnology. At that time we identified the need for a comprehensive policy framework f...

gold preparations are one of the oldest disease modifying drugs in the treatment of rheumatoid arthritis. this are different reports about the effects and complications of these compoumis. these opposite reports may he due to the difference in genetic ami ethnic background of patients. this study was designed to evaluate our results in gold therapy ami compare them with those of western countri...
