Commissioning genetic modification: The marginalisation of dissent in the royal commission on genetic modification
The Royal Commission on Genetic Modification (RCGM) appeared to be a 'public debate'. It sought the participation of people from a cross-section of society according to its broad terms of reference, and invited input on 'options' for the nation. The majority of the public and special interest …

The prospects for human germline genetic modification: scientific and bioethical considerations
… considers the prospects for human germline genetic modification (HGGM) via a synthesis of scientific and bioethical concepts. Eleven published scientific and philosophical papers form the basis for the thesis. The published work deals with the science, technology and wider implications of …

The U.S. Print Media's Framing of the Genetic Modification of Food
In the last decade, the prevalence of genetically modified organisms (GMOs) within the American food supply has rapidly increased, with some experts estimating their presence in 80% of all U.S. food products. Unlike many other parts of the world, consumer opposition to this biotechnology has been …

Development of a Genetic Modification System in <i>Clostridium scatologenes</i> ATCC 25775 for Generation of Mutants
… it is necessary to develop a system to allow genetic modification in <i>Clostridium scatologenes</i> ATCC 25775. Bacteriophages and transposons are useful tools to achieve this goal. Isolation of <i>Clostridium scatologenes</i> ATCC 25775 bacteriophage was attempted by prophage induction and …

Improved iron and zinc availability in sorghum by phytate reduction through genetic modification, fermentation and phytase addition
… sorghum and maize phytate content through genetic modification (GM) on in vitro iron and zinc availability in porridges and raw cereal lager brewer’s wort. The effect of phytate reduction through GM on iron and zinc availability was also compared with the effect of phytate reduction through …

Behavior of passaged chondrocytes in collagen-glycosaminoglycan scaffolds : effects of cross-linking, mechanical loading, and genetic modification of the scaffold
Tissue engineering is a promising solution to the problematic healing of cartilage defects. The purpose of this thesis was to establish a foundation for the development of a collagen-glycosaminoglycan (CG) scaffold for articular cartilage tissue engineering by exploring the behavior of passaged …

Genetic modification of the homomorphic sex chromosomes in the yellow fever mosquito Aedes aegypti provides novel insights and tools for biocontrol
… of arboviral infections still occur each year. Genetic biocontrol, which includes the mass release of sterile, incompatible, or modified males, is a promising approach. However, to prevent the release of females that can potentially transmit pathogens, efficient and accurate sex separation of …

Organisational identities and rationalities: A rhetorical and discourse analysis of organisational communication about genetic modification in the New Zealand kiwifruit and dairy industries
… with the highly controversial practice of genetic modification. This was in an effort to maintain their dominance in export markets, at a time when genetically modified foods were on the one hand regarded as a possible liability in the marketplace, and on the other hand offered the apparent …

Modification of a plant-based expression system to produce Lysosomal Acid Lipase (LAL) in plant cells using genetic modification of endogenous plant N-glycosylation
As plant cells are capable of complex N-glycosylation they are a valid expression system to produce safe and correctly glycosylated human proteins. To modify plant glycosylation patterns towards fully human patterns, the plant glycosylation machinery requires substitution of a series of plant …

The impact of the national bioengineered food disclosure standard and its methods of disclosure on consumer preferences for gene edited and genetically modified foods
… food produced with, or containing, certain plant genetic improvement techniques - such as genetic modification. The standard introduces the new term “Bioengineered” on the approved label, which can be disclosed through methods such as a symbol, text, QR code, and mobile text message. Advances in …

Testing USDA Certified Organic and Non-GMO Verified Project Labeled Foods for the Presence of Genetic Modifications
<p>Genetically Modified Organisms (GMOs) are plants or animals that have been produced using genetic insertion or deletion via technology (also called genetic engineering or GE). Merged DNA from different species creates combinations of plant, animal, bacteria and/or virus genes that cannot occur …

Enabling Cl-Based bioconversion with metabolic engineering
… biochemically, and limited tools exist for their genetic modification. This leaves the metabolic engineer with a choice: to develop genetic tools to enable engineering in the desired host, or to import the relevant catabolic pathway into a more tractable organism, such as Escherichia coli. This …
