Detection and quantification of transgenes are important in analyzing genetically modified organisms (GMOs). Quantitative polymerase chain reaction (qPCR) is commonly utilized for such purposes. However, qPCR has certain limitations in detecting and quantifying transgenes in GMOs, such as the need of certified reference materials, a standard curve, and possible affection by inhibitors. Therefor...
This paper presents results of a collaborative trial study (IUPAC project No. 650/93/97) involving 29 laboratories in 13 countries applying a method for detecting genetically modified organisms (GMOs) in food. The method is based on using the polymerase chain reaction to determine the 35S promotor and the NOS terminator for detection of GMOs. reference materials were produced that were derived ...
In many domains, risk assessment is a defined methodology aimed at determining and quantifying risks associated with a specific activity, including the identification and characterization of potential hazards and their probability of occurrence. It relies on the gathering and interpretation of scientific and technical data and must be carried out in a scientifically sound and transparent manner...
From a study of BAL + IR + Fe ii QSOs (using deep Gemini GMOS-IFU spectroscopy) new results are presented: for IRAS 04505−2958. Specifically, we have studied in detail the out flow (OF) process and their associated structures, mainly at two large galactic scales: (i) two blobs at radius r ∼0.2 and 0.4 (∼1.1 and 2.2 kpc); and (ii) an external hyper giant symmetric shell at r ∼2.0 (11 kpc). In ad...
Most governments have developed, or are developing, national biosafety frameworks to enable them to address known and potential risks associated with the introduction of GMOs into their territories, and these regulatory systems may have a great impact on biotechnology research – not only at the stage of environmental testing, but also during laboratory studies. These national systems are in tur...
We summarize the major points of international debate on health risk studies for the main commercialized edible GMOs. These GMOs are soy, maize and oilseed rape designed to contain new pesticide residues since they have been modified to be herbicide-tolerant (mostly to Roundup) or to produce mutated Bt toxins. The debated alimentary chronic risks may come from unpredictable insertional mutagene...
The application of gene technology is becoming widespread much thanks to the rapid increase in technology, resource, and knowledge availability. Consequently, the diversity and number of genetically modified organisms (GMOs) that may find their way into the food chain or the environment, intended or unintended, is rapidly growing. From a safety point of view the ability to detect and characteri...
The objective of this study was to investigate knowledge about, opinions on and attitudes toward and finally readiness to accept genetically modified organisms (GMO) among Slovenian teachers. On average, they have higher levels of knowledge in classical genetics, and poor levels of knowledge about modern issues in biotechnology, and their attitudes toward GMOs are not extreme. They make decisio...
The present report is the outcome of Project "Scientific and technical contribution to the development of an overall health strategy in thearea of GMOs" carried out by the Biotechnology & GMOs Unit of the Institute for Health and Consumer Protection (Joint Research Centre) inthe frame of contract CT 30249, requested by the European Parliament Committee on Industry, Research and Energy. ...
Regulations for both the labeling and the traceability of GMOs in food and feed chains are coming into force worldwide. Turkey is one of the countries enforcing labeling of food products containing GMOs. For this purpose, reliable and accurate detection methods are a necessity. PCR-based methods are the most common and reliable methods developed thus far. The aim of our study was to evaluate th...
