| ABSTRACT In Brazil, there are several crops producing oil for biofuel production, such as canola, sunflower, peanut, cotton, castor bean, soybean, among others. There are parameters that indicate the energetic and economic viability for the production of biofuels, and that can be applied, for example, in transgenic soybeans. The present study aimed to evaluate the energetic viability of Intacta RR2 PROTM soybean for biofuel production.Experiments were conducted in the municipalities of Palotina and Marechal Cândido Rondon, both in the State of Paraná. Energy balance calculations were carried out from the production system, estimating energy expenditure, including the agricultural and industrial stages. The inputs used were considered as input of energy,... |

| When the application of pesticides places selective evolutionary pressure on pest populations, it can be useful to plant refuge areas-crop areas intended to encourage the breeding of pests that are susceptible to the pesticide. Renewed interest in refuge areas has arisen with recent advances in biotechnology and genetically modified (GM) crops. In this paper, we use a simple model of the evolution of pest resistance to characterize the socially optimal refuge strategy for managing pest resistance. We demonstrate some interesting analogies with other models of renewable resource management, such as those of fisheries. Among the analogous results are findings that maintaining what we might call "maximal sustainable susceptibility" is typically not... |

| In human body, nanorobot-like red blood cells get exposed to human body fluids and many physico-chemical changes inside while these nanorobots (fullerene structure coated hemoglobin embedded iron inorganic elements) remain safe and perform killer action against bacteria or virus. We propose this killer action as ‘nanorobot driven nanomedical treatment’ to combat a bacterial or viral infection. The red cells also act as imaging agent due to oxygen binding character. Our experiments were focused on the application of nanorobot (red cells) to make them immune resistant against viruses and making them as useful contrast agents in magnetic resonance imaging use based on their behavior in nanomagnetic fields. It consists of an injection of... |

| Biomimetic nano-assembly formation offers a convenient and bio friendly approach to fabricate complex structures from simple components with sub-nanometer precision. Recently, extract from cells of microorganism/plant origin have emerged as a simple and viable route for the synthesis of metal and inorganic material nano-particles. In the present study, we have extended biological synthesis of nano-particles to organic molecules, namely the anticancer agent, 5-fluorouracil (5-FU) using Aloe vera leaf extract. The formation of 5-FU nano- particles was assessed by UV, FT-IR and fluorescence spectroscopic techniques. Transmission electron microscopy and atomic force microscopic techniques confirmed nano-size of the synthesized particles. Importantly, the... |

| ABSTRACT The use of biopharmaceuticals dates from the 19th century and within 5-10 years, up to 50% of all drugs in development will be biopharmaceuticals. In the 1980s, the biopharmaceutical industry experienced a significant growth in the production and approval of recombinant proteins such as interferons (IFN α, β, and γ) and growth hormones. The production of biopharmaceuticals, known as bioprocess, involves a wide range of techniques. In this review, we discuss the technology involved in the bioprocess and describe the available strategies and main advances in microbial fermentation and purification process to obtain biopharmaceuticals. |

| Biobanks are an important source to obtain samples and data for research purposes for a wide array of communities. In fact, sharing of bio-resources and data is an integral part of a biobank's role. For an effective partnership a list of requirements or needs have to be met, assuring quality of the resources shared as well as quality of the collaboration in general. Tracking and documenting bio-resource sharing and collaborations of a biobank can be seen as one indicator of the "impact" a biobank has to the field. As an example, the practice of the Estonian Genome Center of the University of Tartu is presented. |

| Development and deployment of genetically engineered crops requires effective environmental and food safety assessment capacity. In-country expertise is needed to make locally appropriate decisions. In April 2007, biosafety and biotechnology scientists, regulators, educators, and communicators from Kenya, Tanzania, and Uganda, met to examine the status and needs of biosafety training and educational programs in East Africa. Workshop participants emphasized the importance of developing biosafety capacity within their countries and regionally. Key recommendations included identification of key biosafety curricular components for university students; collaboration among institutions and countries; development of informational materials for non-academic... |

| Resumo As pesquisas com fungos em busca de substâncias com potencial atividade biológica ganham cada vez mais destaque por serem fontes sustentáveis de novas moléculas. Diplodia pinea é um fungo fitopatogênico encontrado em espécies florestais, que tem apresentado poucos relatos de moléculas com atividade biológica e pode apresentar potencial biotecnológico promissor. Assim, o objetivo deste estudo foi detectar substâncias produzidas por esse fungo em meio líquido, sob condições de estresse. Um metabólito foi detectado na fração alcoólica e caracterizado por difração de raios-X como D-manitol. Esta é a primeira descrição deste monossacarídeo produzido por D. pinea. Abstract Research with fungi in search of substances with potential biological activity is... |

| Biotechnology has had an important impact on the agricultural and food industries over the last twelve years by way of fast and extensive adoption of a few genetically modified (GM) crops. This has produced large efficiency gains, including higher yields and reduced costs of weed and pest control, as well as some environmental benefits. The expected development of crops with additional agronomic traits, and with output traits to improve the nutrition and health attributes of food products, holds the potential for even more pervasive impacts. Full realisation of such promises may require overcoming the constraining effects of restrictive GM product regulations. |

| This work presents a conceptual analysis of the main biotechnologies used in Chilean salmoniculture, which is based on the production of Atlantic salmon (Salmo salar, 356.407 t),silver salmon or coho (Oncorhynchus kisutch, 116.481 t), (O. tshawytscha, 2.062 t) and rainbow trout (O. mykiss, 189.178 t).These activities are focused on the photoperiod artificial manipulation to obtain out-of-season spawning, in the use of hormonal therapies which allow synchronizing the final oocyte maturation (FOM) and sexual maturity acceleration or the increase in milt volume produced by males. Such actions are carried out using GnRHa in doses close to 10 µg/kg of fish. Once sexual maturity is reached, in vitro manipulation of gamets must often be done due to either the... |
