Two new 5-oxomilbemycins, 27-aldehyde-5-oxomilbemycin β12 (1) and 2-hydroxymilbemycin K (2), were isolated from a genetically engineered strain Streptomyces bingchenggensis BCJ60. Their structures were determined by comprehensive analyses of its 1 H and 13 C NMR, COSY, HMQC, and HMBC spectroscopic, HRESI-MS mass spectrometric and comparison with data from the literature. Preliminary studies sho...

Biosafety of genetically modified organisms (GMOs) and their derivatives is still a major topic in the agenda of government and societies worldwide. The aim of this review is to bring into light that data that supported the decision taken back in 1998 as an exercise to stimulate criticism from the scientific community for upcoming discussions and to avoid emotional and senseless arguments that ...

In most countries, systems are in place to analyse food products for the potential presence of genetically modified organisms (GMOs), to enforce labelling requirements and to screen for the potential presence of unauthorised GMOs. With the growing number of GMOs on the world market, a larger diversity of methods is required for informative analyses. In this paper, the specificity of an extended...

Genetically modified organisms (GMOs) can be defined as organisms in which the genetic material (DNA) has been altered in a way that does not occur naturally. The technology is often called “modern biotechnology” or “gene technology”, sometimes also “recombinant DNA technology” or “genetic engineering”. It allows selected individual genes to be transferred from one organism into another, also b...

This document provides an opinion of the Scientific Panel on Genetically Modified Organisms (GMO Panel) of the European Food Safety Authority (EFSA) on genetically modified maize MON 863 and the maize hybrid MON 863 x MON 810. The opinion is based on two questions raised by the Commission related to applications for the placing of the maize on the market by Monsanto under the Novel Food Regulat...

1.1 Purpose The use of genetically modified organisms (GMOs) in agriculture is rising, but not without debate. There are many scientists who argue that genetic engineering in agriculture is the best way to solve many issues of poverty, food security, environmental harm, and the need for increasing competitiveness in sales, but others raise ethical issues regarding the health of the people who c...

in this study, the vibration behavior of functional graded (fg) circular and annular nanoplate embedded in a visco-pasternak foundation and coupled with temperature change is studied. the effect of in-plane pre-load and temperature change are investigated on the vibration frequencies of fg circular and annular nanoplate. to obtain the vibration frequencies of the fg circular and annular nanopla...

background: toxoplasma gondii infection is widely prevalent in many species of warm-blooded animals including human. the aim of this study was to determine the prevalence of antibodies to t. gondii from slaughtered sleep and goats by mod­ified agglutination test (mat) in kerman region , southeastern iran. methods : altogether 1340 blood samples were collected from 562 sheep and 778 goats from a...
