Abstract: Crystal proteins (Cry) produced during the growth and sporulation phases of Bacillus thuringiensis (Bt) bacterium are known as delta endotoxins. These toxins are being used worldwide as bioinsecticides to control pests in agriculture, and some Cry toxins are used against mosquitoes to control vector transmission. This review summarizes the relevant information currently available regarding the …

Abstract: Recently, a debate on international regulation is ongoing on the capacity to predict and avoid adverse effects on health and environment of new products and novel food/feed (GMOs, chemicals, pesticides, nanoparticles …). The health risks assessment cannot avoid the study of blood analyses of mammals eating these products in subchronic or chronic tests. Mammalian …

ГМ (генетически модифицированная) соя и её субпродукты широко используются при производстве большого числа продуктов питания для человека и кормов для сельскохозяйственных и лабораторных животных. Однако возможные негативные последствия такого широкомасштабного использования ГМ …

Abstract: Context – Among the 134 million hectares of genetically modified plants growing worldwide in 2009, more than 99.9 % are described as pesticide plants (Clive 2009). Around 80 % are tolerant to Roundup, a glyphosate based herbicide. Its use on GMOs is thus amplified, and this phenomenon shed a new light on the problem …

Text: Существуют многочисленные данные о негативном воздействии генетически модифицированных организмов (ГМО) на организм млекопитающих. Так, были выявлены патологические изменения в органах при добавлении в корм животных ГМ-картофеля, ГМ-кукурузы, ГМ-гороха и ГМ-сои (Puzstai, 1999; Ewen and Puzstai, 1999; Malatesta et al., 2002, 2003; Prescott et al., 2005; Seralini et al., 2007 и др.). Однако практически нет …

Abstract: In glyphosate (G)-based herbicides (GBHs), the declared active principle G is mixed with several adjuvants that help it to penetrate the plants’ cell membranes and its stabilization and liposolubility. Its utilization is growing with genetically modified organisms engineered to tolerate GBH. Millions of farmers suffer poisoning and death in developing countries, and occupational exposures …

Abstract: This article summarises data about glyphosate-tolerant (“Roundup ready”) genetically modified soybean influence on animals’ organism. The influence of herbicide glyphosate on the organism of plants and animals, which is widely used herbicide in agriculture in the most countries of the world, is considered. Each year, the use of “Roundup” herbicide increases, as weeds become …

Abstract: Our previous studies have demonstrated that stable microRNAs (miRNAs) in mammalian serum and plasma are actively secreted from tissues and cells and can serve as a novel class of biomarkers for diseases, and act as signaling molecules in intercellular communication. Here, we report the surprising finding that exogenous plant miRNAs are present in the …

Abstract: Formulated and sporulated cultures of Bacillus thuringiensis (Bt) have been widely used against insect pests, but after the advent of genetically modified plants expressing δ-endotoxins, the bioavailability of Cry proteins has been increased. For biosafety reasons their adverse effects should be studied, mainly for non-target organisms. Thus, we evaluated, in Swiss albino mice, the …

Abstract: MADISON, WISCONSIN—More than 3000 ecologists gathered here from 5 to 10 August for the 86th annual meeting of the Ecological Society of America (ESA). Hot topics included trees and global warming (see “Forests: No Greenhouse Antidote?”), the risks of transgenic crops (see below), and vanishing tropical mammals (see “Case of the Missing Mammals”). Keywords: …

Abstract: Our recent work (Séralini et al., 2012) remains to date the most detailed study involving the life-long consumption of an agricultural genetically modified organism (GMO). This is true especially for NK603 maize for which only a 90-day test for commercial release was previously conducted using the same rat strain (Hammond et al., 2004). It …

Abstract: Bacillus thuringiensis (B.t.) is a live microorganism that kills certain insects and is used to kill unwanted insects in forests, agriculture, and urban areas. In a purified form, some of the proteins produced by B.t. are acutely toxic to mammals. However, in their natural form, acute toxicity of commonly-used B.t. varieties is limited to …

Abstract: Dicamba is a benzoic acid herbicide that has been detected in surface and ground water. The herbicide has been shown to have cytogeneic and DNA damaging effects and to cause organ damage in mammals; however, little is known about the endocrine disrupting effects of dicamba in fish. In this study, histological changes, plasma vitellogenin …

Text: Widespread distribution of genetically modified organisms (GMO) causes great biological risks for human and the Environment. Three kind of biological risks are described usually: ecological, nutrition and agrotechnical. The term genetically modified organisms (GMOs) refers to plants, microbes and animals with genes transferred from other species in order to produce certain novel characteristics (for …

Abstract: Roundup® is extensively used for weed control worldwide. Residues of this compound may lead to side effects of the male reproductive system. However, the toxic effects and mechanisms of Roundup® of male germ cells remain unclear. We aimed to investigate the apoptosis-inducing effects of Roundup® on mouse male germ cells and explore the role …

Abstract: Purpose. We reviewed 19 studies of mammals fed with commercialized genetically modified soybean and maize which represent, per trait and plant, more than 80% of all environmental genetically modified organisms (GMOs) cultivated on a large scale, after they were modified to tolerate or produce a pesticide. We have also obtained the raw data of …

Abstract: Agriculture forms a basis for survival and advancement of civilization of mankind and economic growth. The production and quality of food depends on nature of cultivars that have hitherto been obtained by mutation and hybridization of selected plants. Since the productivity of many crops has reached a plateau the gene transfer technology is used …

Abstract: Roundup is a glyphosate-based herbicide used worldwide, including on most genetically modified plants that have been designed to tolerate it. Its residues may thus enter the food chain, and glyphosate is found as a contaminant in rivers. Some agricultural workers using glyphosate have pregnancy problems, but its mechanism of action in mammals is questioned. …

Abstract: On an independent modern farm followed by certified veterinarians, dairy cows (mean of 62 per year) were maintained in optimized milk production for 3 years each. From 1997 to 2002, just after the commercial release of the first GMO (genetically modified organism) in Europe, genetically modified (GM) Bt176 maize grown on the farm was …

To the editor: Your May 29 editorial1 about the health risks of genetically modified (GM) food was apposite and addresses some of the important medical issues vigorously. It beggars belief that “badly designed, poorly carried out, inaccurately interpreted experiments” could have perpetuated such profound public debate for almost a year. Regrettably, among the correspondents who …

Abstract: The herbicide glyphosate, N-(phosphonomethyl) glycine, has been used extensively in the past 40 years, under the assumption that side effects were minimal. However, in recent years, concerns have increased worldwide about the potential wide ranging direct and indirect health effects of the large scale use of glyphosate. In 2015, the World Health Organization reclassified …

Abstract: In 1977 several patients were seen with soft-tissue sarcomas and previous exposure to phenoxy acids. This clinical observation resulted in a cases-referent (case-control) study being undertaken which showed that exposure to phenoxy acids or chlorophenols, which are chemically related, gave a roughly six-fold increase in the risk for this type of tumour. A further …

Abstract: The use of biosynthetic milk hormones raises fundamental ethical, social, and economic considerations, including the continued viability of the small family dairy farm and adverse veterinary effects. The past and expanding use of synthetic bovine growth hormone manufactured by the Agricultural Chemicals Division of Elanco (Eli Lilly and Co.) in conjunction with Dow Chemical …

Introduction: Residues of the commonly-used herbicide glyphosate have been found in a variety of fruits and vegetables. Residues can be detected long after glyphosate treatments have been made. Lettuce, carrots, and barley planted a year after glyphosate treatment contained residues at harvest. In California, where reporting of pesticide-caused illnesses is more comprehensive than in other …
