GMO Research
Abstract: BACKGROUND, AIM, AND SCOPE: The possibility of gene transfer from genetically modified oilseed rape (OSR) to its cultivated or wild relatives is of concern since its commercial cultivation, because of its potential weediness and impact on the environment. Introgression of modified genes can affect conservation of agricultural crops, because there are many cultivars and …
Abstract: Accumulation of information about natural hybridization between GM soybean (Glycine max) and wild soybean (Glycine soja) is required for risk assessment evaluation and to establish biosafety regulations in Japan. This is particularly important in areas where wild relatives of cultivated soybean are grown (i.e. East Asia including Japan). To collect information on temporal and …
Abstract: Monitoring for escape of genetically modified (GM) oilseed rape (Brassica napus) during transport can be performed by means of roadside evaluations in areas where cultivation of this GM crop is not conducted, such as in Japan. We performed a survey of oilseed rape plants growing along a 20-km section of Japan’s Route 51, one …
Abstract: An investigation was carried out to monitor the escape and spread of oilseed rape (Brassica napus) transgenic plants and the introgression of transgenes to its closely related feral species in Japan. We screened a total of about 7500 feral B. napus, 300 B. rapa, and 5800 B. juncea seedlings from maternal plants in 143 …
Abstract: The global expansion in the development and cultivation of genetically modified (GM) crops has increased international concern about adventitious presence of GM materials in non-GM seeds and grains. GM events in canola, corn, soybean, cotton, flax, papaya, potato, squash, sugar beet, and tomato have received regulatory approval in Canada. However, GM cultivars are only …
Abstract: The discovery of StarLink corn in U.S. food products caused considerable disruption in corn markets in 2000 and 2001. Segregation costs were incurred by the U.S. grain‐handling system in order to ensure that domestic and export sales of food corn and export sales of non‐food corn to Japan meet stringent tolerance levels. These costs …
Abstract: StarLink disrupted the U.S. corn market during the 2000/01 marketing year as a result of inadvertent commingling. The potential, upper‐bound volume of marketed StarLink‐commingled corn from the 2000 crop located near wet and dry millers prior to October 1, 2000, is estimated at 124 million bushels. The percentage of corn shipments that tested positive …
Abstract: Widespread interest in producing transgenic organisms is balanced by concern over ecological hazards, such as species extinction if such organisms were to be released into nature. An ecological risk associated with the introduction of a transgenic organism is that the transgene, though rare, can spread in a natural population. An increase in transgene frequency …
Abstract: Toxic effects of glufosinate ammonium (GLA), a non-selective herbicide, on the brain of infantile rats was studied. Because of the structural analogy between GLA and glutamate, GLA-exposed rats were examined for the wet-dog shakes response to kainic acid. Seven-day-old female rats were injected subcutaneously with a dose 1, 2 or 5 mg/kg GLA daily …
Abstract: Investigators hope to track origins of the transgenic crop. Text: It has been nearly three months since an Oregon farmer discovered unapproved transgenic wheat in a commercial wheat field, triggering bans on imports of US wheat into Japan and South Korea. The harvest season has now begun, and with the contamination proving to be …
Abstract: Virtually all scientists agree that the commonly used methods for inserting new genes into the genome of a crop plant (genetic engineering or genetic modification): (1) are imprecise and uncontrolled, (2) can impact biological functioning unpredictably, and (3) can lead to unintended harm to health and the environment. The intentional use of GMOs (genetically …
Text: In our lifetime we are experiencing never before seen rates of obesity, with a 68% rate of overweight in adults. In my field of gynecologic oncology, our surgical cases have become tremendously challenging due to the large size of our patients. When I was in residency training in the mid 1980s, it was rare …
Abstract: Glufosinate ammonium, which is a component of the herbicide BASTA, is a phosphinic analog of glutamic acid. Its activity is related to the inhibition of glutamine synthetase. Previous studies demonstrated that glufosinate has no teratogenic potential in rats and rabbits in vivo. In the present study, we determined whether glufosinate could affect embryonic development …
Abstract: The planting of transgenic crops expressing Bacillus thuringiensis endotoxins is widespread throughout the world; the prolific increase in their application exposes nontarget organisms to toxins designed to control pests. To date, studies have focused upon the effects of Bt endotoxins on specific herbivores and detritivores, without consideration of their persistence within arthropod food webs. …
Abstract: The aim of this study was to evaluate the possible hepatorenal toxicity and genotoxicity from eating meat meal of genetically modified (GM) Japanese quail in 90 days dietary experiment using micronucleus (MN) test, mitotic index (MI) and RAPD-PCR for genotoxicity assay, ALT, AST, urea and creatinine for hepatorenal toxicity. Four groups of Swiss male …
