Cell death localization in situ in laboratory reared honey bee (Apis mellifera L.) larvae treated with pesticides
Abstract: In this study, cell death detected by DNA fragmentation labeling and phosphatidylserine (PS) localization was investigated in the honey bee (Apis mellifera L.) midgut, salivary glands and ovaries after treating larvae with different pesticides offered via an artificial diet. To do this, honey bee larvae reared in an incubator were exposed to one of …
Dicamba affects sex steroid hormone level and mRNA expression of related genes in adult rare minnow (Gobiocypris rarus) at environmentally relevant concentrations
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 …
Agriculture Alters Gonadal Form and Function in the Toad Bufo marinus
Abstract: Background Many agricultural contaminants disrupt endocrine systems of wildlife. However, evidence of endocrine disruption in wild amphibians living in agricultural areas has been controversial. Typically, studies on the effects of pollutants on wildlife attempt to compare polluted with unpolluted sites. Objectives We took a novel approach to address this question by explicitly quantifying the …
Morphological and cytological features of organism of Mice, who consumed genetically modified potato (Solanum Tuberosum L.) with gene for acyl-lipid ∆9-desaturase
Abstract: The problems of the introduction of transgenic products into the consumer market were examined. The impact of the genetically modified potatoes on the cytological and morphological parameters in mice was investigated. An increase in body mass and in hearts mass and a decrease in spleens mass, degeneration of the ovaries and changing of the …
Morphological and cytological features of organism of mice, who consumed genetically modified potato (Solanum Tuberosum L.) with gene SMAMP-2
Abstract: The article is devoted to the introduction of transgenic products into the consumer market. The impact of the genetically modified potatoes on the cytological and morphological parameters of mice was investigated. Transgenic potato plants were produced by agrobacterium-mediated transformation using genetic constructions 35S-proSmAMP with marker gene npt11 of the resistance to the kanamycin. An increase in hearts …
Biological effects of transgenic Bt cotton seeds fed in long term reproduction studies in rat
Abstract: The present study was designed to evaluate the impact of feeding a line of genetically modified cotton seeds (Bt cotton seeds) to that of standard diet and reference diet (Non-Bt cotton seeds) on growth, metabolism in albino rats. Non-Bt and Bt cotton seeds were incorporated into the diet of the albino rats at a …
BT BRINJAL Event EE1: The Scope and Adequacy of the GEAC Toxicological Risk Assessment. Review of Oral Toxicity Studies in Rats
Abstract: This evaluation of Bt brinjal studies is based on requirements for a rigorous evaluation of food safety for the people of India and their health. Departures from Indian and international published standards for the 14-day and 90-day studies are a cause for concern 1. The current food safety studies for Bt brinjal were not …
Predictions of biodiversity response to genetically modified herbicide-tolerant crops
Abstract: We simulated the effects of the introduction of genetically modified herbicide-tolerant (GMHT) crops on weed populations and the consequences for seed-eating birds. We predict that weed populations might be reduced to low levels or practically eradicated, depending on the exact form of management. Consequent effects on the local use of fields by birds might …
