This study questions the presumed relation between formal schooling and scientific literacy about biotechnologies. Comparing science and nonscience majors' knowledge of and attitudes toward biotechnological applications, conclusions are drawn if their formal learnings improve pupils' understandings of and attitudes toward biotechnology applications. Sample of the study consists of 403 undergraduate and graduate students, 198 nonscience, and 205 science majors. The Biotechnology Knowledge Questionnaire and the Biotechnology Attitude Questionnaire were administered. Descriptive statistics (mean and percentages), t test, and correlations were used to examine the participants' knowledge of biotechnology and attitudes toward biotechnological applications and differences as regards their majors. Although the science majors had higher knowledge and attitude scores than the nonscience majors, it is not possible to say that they have sufficient knowledge of biotechnologies. Besides, the participants' attitudes toward biotechnological applications were not considerably related to their knowledge of biotechnology. © 2016 by The International Union of Biochemistry and Molecular Biology, 45(2):115-125, 2017. © 2016 The International Union of Biochemistry and Molecular Biology.

"Othering" agricultural biotechnology: Slovenian media representation of agricultural biotechnology.

Science.gov (United States)

Zajc, Jožica; Erjavec, Karmen

2014-08-01

While studies on media representations of agricultural biotechnology mostly analyse media texts, this work is intended to fill a research gap with an analysis of journalistic interpretations of media representations. The purpose of this project was to determine how news media represent agricultural biotechnology and how journalists interpret their own representations. A content and critical discourse analysis of news texts published in the Slovenian media over two years and in-depth interviews with their authors were conducted. News texts results suggest that most of the news posts were "othering" biotechnology and biotechnologists: biotechnology as a science and individual scientists are represented as "they," who are socially irresponsible, ignorant, arrogant, and "our" enemies who produce unnatural processes and work for biotechnology companies, whose greed is destroying people, animals, and the environment. Most journalists consider these representations to be objective because they have published the biotechnologists' opinions, despite their own negative attitudes towards biotechnology.

Stabnikov, Viktor; Ivanov, Volodymyr; Chu, Jian

2015-09-01

A new scientific and engineering discipline, Construction Biotechnology, is developing exponentially during the last decade. The major directions of this discipline are selection of microorganisms and development of the microbially-mediated construction processes and biotechnologies for the production of construction biomaterials. The products of construction biotechnologies are low cost, sustainable, and environmentally friendly microbial biocements and biogrouts for the construction ground improvement. The microbial polysaccharides are used as admixtures for cement. Microbially produced biodegradable bioplastics can be used for the temporarily constructions. The bioagents that are used in construction biotechnologies are either pure or enrichment cultures of microorganisms or activated indigenous microorganisms of soil. The applications of microorganisms in the construction processes are bioaggregation, biocementation, bioclogging, and biodesaturation of soil. The biotechnologically produced construction materials and the microbially-mediated construction technologies have a lot of advantages in comparison with the conventional construction materials and processes. Proper practical implementations of construction biotechnologies could give significant economic and environmental benefits.

Modern biotechnology is one of the most important scientific and technological revolutions in the 21st century, with an increasing and measurable impact on society. Development of biotechnology curriculum has become important to high school bioscience classrooms. This study has monitored high school students in Taiwan on their knowledge of and attitudes towards biotechnology for nearly two decades. Not surprisingly, knowledge of biotechnology of current students has increased significantly (p students have learned some definitions and examples of biotechnology. There was a positive correlation between biotechnology knowledge and attitudes toward biotechnology for current students who study Advanced Biology (AB). However, for current students who did not study AB, there was a negative correlation.The attitude results showed that students today expressed less favorable opinions toward agricultural biotechnology (p students today and 18 years ago in opinions towards medical biotechnology. In addition, current students showed a greater concern involving environmental risks than former students. Interestingly, the high school curriculum did affect students' attitudes toward genetically engineered (GE) plants but not GE animals. Our current study also found that the students' attitude towards GE animals was influenced more by their limited knowledge than by their moral belief. On the basis of findings from this study, we suggest that more materials of emerging animal biotechnology should be included in high school curriculum and recommend that high school teachers and university faculty establish a collaborative framework in the near future. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(5):475-491, 2016. © 2016 The International Union of Biochemistry and Molecular Biology.

Thirty years of European biotechnology programmes: from biomolecular engineering to the bioeconomy.

Science.gov (United States)

Aguilar, Alfredo; Magnien, Etienne; Thomas, Daniel

2013-06-25

This article traces back thirty years of biotechnology research sponsored by the European Union (EU). It outlines the crucial role played by De Nettancourt, Goffeau and Van Hoeck to promote and prepare the first European programme on biotechnology (1982-1986) run by the European Commission. Following this first biotechnology programme, others followed until the current one, part of the seventh Framework Programme for Research, Technological Development and Demonstration (2007-2013) (FP7). Particular attention is given to the statutory role of the European institutions in the design and orientation of the successive biotechnology programmes, compared to the more informal-yet visionary-role of key individuals upstream to any legislative decision. Examples of success stories and of the role of the biotechnology programmes in addressing societal issues and industrial competitiveness are also presented. Finally, an outline of Horizon 2020, the successor of FP7, is described, together with the role of biotechnology in building the bioeconomy. Copyright © 2012 Elsevier B.V. All rights reserved.

New crops are gradually establishing along with cultivation systems to reduce reliance on depleting fossil fuel reserves and sustain better adaptation to climate change. These biological assets could be efficiently exploited as bioenergy feedstocks. Bioenergy crops are versatile renewable sources with the potential to alternatively contribute on a daily basis towards the coverage of modern society's energy demands. Biotechnology may facilitate the breeding of elite energy crop genotypes, better suited for bio-processing and subsequent use that will improve efficiency, further reduce costs, and enhance the environmental benefits of biofuels. Innovative molecular techniques may improve a broad range of important features including biomass yield, product quality and resistance to biotic factors like pests or microbial diseases or environmental cues such as drought, salinity, freezing injury or heat shock. The current review intends to assess the capacity of biotechnological applications to develop a beneficial bioenergy pipeline extending from feedstock development to sustainable biofuel production and provide examples of the current state of the art on future energy crops.

Stochastic volatility and stochastic leverage

DEFF Research Database (Denmark)

Veraart, Almut; Veraart, Luitgard A. M.

This paper proposes the new concept of stochastic leverage in stochastic volatility models. Stochastic leverage refers to a stochastic process which replaces the classical constant correlation parameter between the asset return and the stochastic volatility process. We provide a systematic...... treatment of stochastic leverage and propose to model the stochastic leverage effect explicitly, e.g. by means of a linear transformation of a Jacobi process. Such models are both analytically tractable and allow for a direct economic interpretation. In particular, we propose two new stochastic volatility...... models which allow for a stochastic leverage effect: the generalised Heston model and the generalised Barndorff-Nielsen & Shephard model. We investigate the impact of a stochastic leverage effect in the risk neutral world by focusing on implied volatilities generated by option prices derived from our new...

The Leverage Ratchet Effect

Shareholder-creditor conflicts can create leverage ratchet effects, resulting in inefficient capital structures. Once debt is in place, shareholders may inefficiently increase leverage but avoid reducing it no matter how beneficial leverage reduction might be to total firm value. We present conditions for an irrelevance result under which shareholders view asset sales, pure recapitalization and asset expansion with new equity as equally undesirable. We then analyze how seniority, asset hetero...

Blue biotechnology, in which aquatic environments provide the inspiration for various products such as food additives, aquaculture, biosensors, green chemistry, bioenergy, and pharmaceuticals, holds enormous promise. Large-scale efforts to sequence aquatic genomes and metagenomes, as well as campaigns to isolate new organisms and culture-based screenings, are helping to push the boundaries of known organisms. Mass spectrometry-based proteomics can complement 16S gene sequencing in the effort to discover new organisms of potential relevance to blue biotechnology by facilitating the rapid screening of microbial isolates and by providing in depth profiles of the proteomes and metaproteomes of marine organisms, both model cultivable isolates and, more recently, exotic non-cultivable species and communities. Proteomics has already contributed to blue biotechnology by identifying aquatic proteins with potential applications to food fermentation, the textile industry, and biomedical drug development. In this review, we discuss historical developments in blue biotechnology, the current limitations to the known marine biosphere, and the ways in which mass spectrometry can expand that knowledge. We further speculate about directions that research in blue biotechnology will take given current and near-future technological advancements in mass spectrometry. Copyright © 2014 Elsevier B.V.

Full Text Available According to the broadest definition, biotechnology is the use of living matter (plants, animals and microorganisms in industry, environment protection, medicine and agriculture. Biotechnology takes a key position in the field of food processing during thousands of years. Last about fifty years brought dynamical development of knowledges in the natural sciences especially in domain of genetics and manipulation of genes. Biotechnology for which active role in the on-coming times could be foreseen, not only with respect of R&D, but also in general technological development represents scope of priority in the USA and in European Union (EU as well. It is accepted that the results achieved in biotechnology oversize scientific domain and find their entrance into economics, legislation, quality of life and even of politics. Corresponding with the definition of biotechnology as "the integration of natural sciences and engineering in the application of microorganisms, cells, their components and molecular analogues in production (General assembly of the European federation for Biotechnology, 1989 European Commission (1999 adopted the biotechnological taxonomy, i.e. fields and sub-fields of biotechnology. R&D activities in this domain are oriented to eight fields and branched through them. Fields of biotechnology (EC, 1999 are: 1 Plant biotechnology (agricultural cultivars, trees, bushes etc; 2 Animal biotechnology; 3 Biotechnology in environment protection; 4 Industrial biotechnology (food, feed, paper, textile, pharmaceutical and chemical productions; 5 Industrial biotechnology (production of cells and research of cells - producers of food and of other commodities; 6 Development of humane and veterinarian diagnostics (therapeutical systems 7 Development of the basic biotechnology, and 8 Nontechnical domains of biotechnology.

Biotechnology in India has made great progress in the development of infrastructure, manpower, research and development and manufacturing of biological reagents, biodiagnostics, biotherapeutics, therapeutic and, prophylactic vaccines and biodevices. Many of these indigenous biological reagents, biodiagnostics, therapeutic and prophylactic vaccines and biodevices have been commercialized. Commercially when biotechnology revenue has reached $25 billions in the U.S. alone in 2000 excluding the revenues of biotech companies that were acquired by pharmaceutical companies, India has yet to register a measurable success. The conservative nature and craze of the Indian Industry for marketing imported biotechnology products, lack of Government support, almost non-existing national healthcare system and lack of trained managers for marketing biological and new products seem to be the important factors responsible for poor economic development of biotechnology in India. With the liberalization of Indian economy, more and more imported biotechnology products will enter into the Indian market. The conditions of internal development of biotechnology are not likely to improve in the near future and it is destined to grow only very slowly. Even today biotechnology in India may be called to be in its infancy.

Fungal biodiversity to biotechnology.

Chambergo, Felipe S; Valencia, Estela Y

2016-03-01

Fungal habitats include soil, water, and extreme environments. With around 100,000 fungus species already described, it is estimated that 5.1 million fungus species exist on our planet, making fungi one of the largest and most diverse kingdoms of eukaryotes. Fungi show remarkable metabolic features due to a sophisticated genomic network and are important for the production of biotechnological compounds that greatly impact our society in many ways. In this review, we present the current state of knowledge on fungal biodiversity, with special emphasis on filamentous fungi and the most recent discoveries in the field of identification and production of biotechnological compounds. More than 250 fungus species have been studied to produce these biotechnological compounds. This review focuses on three of the branches generally accepted in biotechnological applications, which have been identified by a color code: red, green, and white for pharmaceutical, agricultural, and industrial biotechnology, respectively. We also discuss future prospects for the use of filamentous fungi in biotechnology application.

Xu, Yan; Wang, Dong; Fan, Wen Lai; Mu, Xiao Qing; Chen, Jian

The earliest industrial biotechnology originated in ancient China and developed into a vibrant industry in traditional Chinese liquor, rice wine, soy sauce, and vinegar. It is now a significant component of the Chinese economy valued annually at about 150 billion RMB. Although the production methods had existed and remained basically unchanged for centuries, modern developments in biotechnology and related fields in the last decades have greatly impacted on these industries and led to numerous technological innovations. In this chapter, the main biochemical processes and related technological innovations in traditional Chinese biotechnology are illustrated with recent advances in functional microbiology, microbial ecology, solid-state fermentation, enzymology, chemistry of impact flavor compounds, and improvements made to relevant traditional industrial facilities. Recent biotechnological advances in making Chinese liquor, rice wine, soy sauce, and vinegar are reviewed.

1999-01-01

In this paper, I investigate whether the effects of monetary policy on firm investment can be transmitted through leverage. I find that monetary contractions reduce the growth of investment more for highly leveraged firms than for less leveraged firms. The results suggest that the board credit channel for monetary policy exists, and that it can operate through leverage, as adverse monetary shocks aggravate real debt burdens and raise the effective costs of investment.

BIOTECHNOLOGY : AN OVERVIEW

John I. Bruce

2012-09-01

Full Text Available Biotechnology as a science includes various aspects of the management and manipulation of biological systems. Recent advances in immunology, molecular biology, cell culture and other associated areas provide an opportunity for scientists to move biology out of the laboratory and into the realms of society. This has many implications which mankind on a whole may not be prepared to cope with at this time. This new capability has been referred to as "Biotechnology". Biotechnology has also been defined as "the integrated use of biochemistry, microbiology, and chemical engineering in order to achieve the capacities of microbes and culture cells". Genetic engineering which includes gene splicing and recombinant DNA-cloning is an example of a recent offshoot of biotechnology. Because of the advent of biotechnology, one can now think of the prospect of engineering tomorrows vaccines. In the past, vaccine development has been laborious and in many instances an unrewarding task. After years of effort only a handful of safe, effective vaccines have emerged. In the biotechnology arena, new methodologies and strategies for immunizing humans and domestic animals against infectious diseases are providing new hope for discovering successful vaccines. While most of the effort in the past has focused on viral vaccine development, attention is now being directed towards vaccines for protection against parasitic diseases. Currently, considerable effort is being made to develop vaccines for malaria, coccidiosis (in fowl, cholera, malaria, schistosomiasis and trypanosomiasis among others.

The term biotechnology first appeared in the programs of the Scientific and Technological Research Council of Turkey (TUBITAK) in 1982. The State Planning Organization (SPO) in 1988 defined biotechnology and the scientific fields. Moreover, it put forward an institutional framework and suggested priority areas for research and development. Turkey has been researching and investing in biotechnology for almost four decades. This review covers the development of science and technology policy with its history, consensus and consequences, bio-industries in Turkey, and research activities in biotechnology at Turkish Universities. Details are provided by the research groups in response to a common request for information on their activities and major publications in the field. The information provided has been grouped under thematic topics within the broad theme of biotechnology, and summarized within these topics. Although many aspects of biotechnological research are being pursued in Turkey, it appears that the most common research activities of the field are in fermentation processes, environmental biotechnology, and biomedical engineering.

The biotechnology and bioeconomy landscape in Malaysia.

Since 1990s Malaysia aspired to make biotechnology and bioeconomy as her engines of economic growth to utlise the abundance of natural resources and biodiversity. The public sector plays an integral role in developing the sector and various incentives are in place for the private sector to be actively involved and to forge collaboration with the public sector. The country launched its National Biotechnology Policy in 2005 and later launched its National Bioeconomy Programme in 2010 to become the first country in South East Asia and second in Asia after China to have such an initiative. Malaysia is also very proactive in its biosafety law and regulations and has most of the related legal instrument in place. A lot of success has been recorded since the inception of the National Biotechnology Policy in terms of job creation, contribution to GDP through biobusinesses and investment from foreign companies, but the sector is not spared from challenges too. Due to the nature of the discipline that is multidisciplinary and that requires huge amount of investment, expertise and political will, there are a lot of barriers before the country emerges as a bioeconomy player. This paper discusses the public policies, initiatives and funding mechanisms in place in Malaysia that drive its research, development and commercialisation in the area of biotechnology and bioeconomy. The authors also discuss the challenges faced in Malaysia in implementing the policies. Copyright © 2017 Elsevier B.V. All rights reserved.

Undoubtedly, biotechnology has a tremendous impact on our daily lives. As a result of this and in parallel to the advancement of knowledge in this field of applied research, consumer awareness of the potential benefits and risks of this technology has steadily increased, leading to a thorough investigation of the public perception of biotechnology in the past years. Indeed, it has become clear that it is in the general interest of science and especially of applied research to inform the public of its advances. A promising next step is to strengthen biotechnology communication in scholastic institutions. In this paper, we investigate the perception of biotechnology in a specific target group, namely high-school students in the 16-20-year-old age range. We conducted a questionnaire-based survey on a total of 1410 students in six European countries to investigate students' perception, concern, scientific knowledge, and awareness. Our data revealed some unexpected patterns of acceptance and concern about biotechnology. Knowledge analysis indicated that pupils lack specific knowledge about biotechnological applications and their interest in biotechnology appeared to be linked to knowledge. Analysis of specific questions about teaching practices at schools suggests that a better targeted choice in media as vehicles for information together with selected speakers could be instrumental in increasing students' interest in science and more specifically in biotechnology.

India has embarked upon a very ambitious program in biotechnology with a view to harnessing its available human and unlimited biodiversity resources. It has mainly been a government sponsored effort with very little private industry participation in investment. The Department of Biotechnology (DBT) established under the Ministry of Science and Technology in 1986 was the major instrument of action to bring together most talents, material resources, and budgetary provisions. It began sponsoring research in molecular biology, agricultural and medical sciences, plant and animal tissue culture, biofertilizers and biopesticides, environment, human genetics, microbial technology, and bioprocess engineering, etc. The establishment of a number of world class bioscience research institutes and provision of large research grants to some existing universities helped in developing specialized centres of biotechnology. Besides DBT, the Department of Science & Technology (DST), also under the Ministry of S&T, sponsors research at universities working in the basic areas of life sciences. Ministry of Education's most pioneering effort was instrumental in the creation of Biochemical Engineering Research Centre at IIT Delhi with substantial assistance from the Swiss Federal Institute of Technology, Zurich, Switzerland to make available state-of-the-art infrastructure for education, training, and research in biochemical engineering and biotechnology in 1974. This initiative catalysed biotechnology training and research at many institutions a few years later. With a brief introduction, the major thrust areas of biotechnology development in India have been reviewed in this India Paper which include education and training, agricultural biotechnology, biofertilizers and biopesticides, tissue culture for tree and woody species, medicinal and aromatic plants, biodiversity conservation and environment, vaccine development, animal, aquaculture, seri and food biotechnology, microbial

We show that there is a negative relation between leverage and future growth at the firm level and, for diversified firms, at the segment level. Further, this negative relation between leverage and growth holds for firms with low Tobin's q, but not for high-q firms or firms in high-q industries. Therefore, leverage does not reduce growth for firms known to have good investment opportunities, but is negatively related to growth for firms whose growth opportunities are either not recognized by ...

To transform developing and least developing countries into industrialised ones, biotechnology could be deployed along the value chain, to provide support to the development of the bio-based industries in such a way to ensure sustainability of the sector and to reduce negative environmental impacts that might otherwise occur. In agribusiness development, for instance, interventions could start from inputs and agricultural mechanization, modern processing technologies, packaging of perishable products, the promotion of food safety in the processing and regulatory environment; and interventions to improve competitiveness and productivity. Worth over USD 300 billion in revenue, the role of the biotechnology goes beyond industrial growth, since it provides opportunities for progress towards many of the UN sustainable development goals (SDGs). This paper reviews the status of industrial biotechnology as it relates to inclusive and sustainable industrial development. Copyright © 2017 Elsevier B.V. All rights reserved.

Yamabhai, Montarop; Sak-Ubol, Suttipong; Srila, Witsanu; Haltrich, Dietmar

2016-01-01

Mannans of different structure and composition are renewable bioresources that can be widely found as components of lignocellulosic biomass in softwood and agricultural wastes, as non-starch reserve polysaccharides in endosperms and vacuoles of a wide variety of plants, as well as a major component of yeast cell walls. Enzymatic hydrolysis of mannans using mannanases is essential in the pre-treatment step during the production of second-generation biofuels and for the production of potentially health-promoting manno-oligosaccharides (MOS). In addition, mannan-degrading enzymes can be employed in various biotechnological applications, such as cleansing and food industries. In this review, fundamental knowledge of mannan structures, sources and functions will be summarized. An update on various aspects of mannan-degrading enzymes as well as the current status of their production, and a critical analysis of the potential application of MOS in food and feed industries will be given. Finally, emerging areas of research on mannan biotechnology will be highlighted.

Multitrophic microbial interactions for eco- and agro-biotechnological processes: theory and practice.

Science.gov (United States)

Saleem, Muhammad; Moe, Luke A

2014-10-01

Multitrophic level microbial loop interactions mediated by protist predators, bacteria, and viruses drive eco- and agro-biotechnological processes such as bioremediation, wastewater treatment, plant growth promotion, and ecosystem functioning. To what extent these microbial interactions are context-dependent in performing biotechnological and ecosystem processes remains largely unstudied. Theory-driven research may advance the understanding of eco-evolutionary processes underlying the patterns and functioning of microbial interactions for successful development of microbe-based biotechnologies for real world applications. This could also be a great avenue to test the validity or limitations of ecology theory for managing diverse microbial resources in an era of altering microbial niches, multitrophic interactions, and microbial diversity loss caused by climate and land use changes.

Dones Tacero, Milagros; Pérez García, Julián; San Román, Antonio Pulido

This paper tries to yield an economic valuation of biotechnological activities in terms of aggregated production and employment. This valuation goes beyond direct estimation and includes the indirect effects derived from sectorial linkages between biotechnological activities and the rest of economic system. To deal with the proposed target several sources of data have been used, including official data from National Statistical Office (INE) such us national accounts, input-output tables, and innovation surveys, as well as, firms' level balance sheets and income statements and also specific information about research projects compiled by Genoma Spain Foundation. Methodological approach is based on the estimation of a new input-output table which includes the biotechnological activities as a specific branch. This table offers both the direct impact of these activities and the main parameters to obtain the induced effects over the rest of the economic system. According to the most updated available figures, biotechnological activities would have directly generated almost 1,600 millions of euros in 2005, and they would be employed more than 9,000 workers. But if we take into account the full linkages with the rest of the system, the macroeconomic impact of Biotechnological activities would reach around 5,000 millions euros in production terms (0.6% of total GDP) and would be responsible, directly or indirectly, of more than 44,000 employments.

The biotechnology innovation machine: a source of intelligent biopharmaceuticals for the pharma industry--mapping biotechnology's success.

The marriage of biotechnology and the pharmaceutical industry (pharma) is predicated on an evolution in technology and product innovation. It has come as a result of advances in both the science and the business practices of the biotechnology sector in the past 30 years. Biotechnology products can be thought of as "intelligent pharmaceuticals," in that they often provide novel mechanisms of action, new approaches to disease control, higher clinical success rates, improved patient care, extended patent protection, and a significant likelihood of reimbursement. Although the first biotechnology product, insulin, was approved just 32 years ago in 1982, today there are more than 200 biotechnology products commercially available. Research has expanded to include more than 900 biotechnology products in clinical trials. Pharma is substantially engaged in both the clinical development of these products and their commercialization.

Importance of lactobacilli in food and feed biotechnology.

Science.gov (United States)

Giraffa, Giorgio; Chanishvili, Nina; Widyastuti, Yantyati

2010-01-01

The genus Lactobacillus is a heterogeneous group of lactic acid bacteria (LAB) with important implications in food fermentation. The ability to colonize a variety of habitats is a direct consequence of the wide metabolic versatility of this group of LAB. Consequently, lactobacilli have been used for decades in food preservation, as starters for dairy products, fermented vegetables, fish and sausages as well as silage inoculants. Lactobacilli have also been proposed as probiotics and microbial cell factories for the production of nutraceuticals. However, a wide range of applications of lactobacilli in food biotechnology remains potential, whereas a number of important strains still need to be discovered and characterized. This article provides an overview of the taxonomy of lactobacilli and describes four of the most significant case studies on the application of this group of LAB in food and feed biotechnology, including their use as probiotics, dairy starters, silage inoculants, and microbial cell factories. The importance of access to and exchange of biological material within and between different strain collections as a crucial step in expanding the range of different biotechnological applications of lactobacilli is also emphasized.

Magnetic separations in biotechnology.

Science.gov (United States)

Borlido, L; Azevedo, A M; Roque, A C A; Aires-Barros, M R

2013-12-01

Magnetic separations are probably one of the most versatile separation processes in biotechnology as they are able to purify cells, viruses, proteins and nucleic acids directly from crude samples. The fast and gentle process in combination with its easy scale-up and automation provide unique advantages over other separation techniques. In the midst of this process are the magnetic adsorbents tailored for the envisioned target and whose complex synthesis spans over multiple fields of science. In this context, this article reviews both the synthesis and tailoring of magnetic adsorbents for bioseparations as well as their ultimate application. Copyright © 2013 Elsevier Inc.

Leverage bubble

Science.gov (United States)

Yan, Wanfeng; Woodard, Ryan; Sornette, Didier

2012-01-01

Leverage is strongly related to liquidity in a market and lack of liquidity is considered a cause and/or consequence of the recent financial crisis. A repurchase agreement is a financial instrument where a security is sold simultaneously with an agreement to buy it back at a later date. Repurchase agreement (repo) market size is a very important element in calculating the overall leverage in a financial market. Therefore, studying the behavior of repo market size can help to understand a process that can contribute to the birth of a financial crisis. We hypothesize that herding behavior among large investors led to massive over-leveraging through the use of repos, resulting in a bubble (built up over the previous years) and subsequent crash in this market in early 2008. We use the Johansen-Ledoit-Sornette (JLS) model of rational expectation bubbles and behavioral finance to study the dynamics of the repo market that led to the crash. The JLS model qualifies a bubble by the presence of characteristic patterns in the price dynamics, called log-periodic power law (LPPL) behavior. We show that there was significant LPPL behavior in the market before that crash and that the predicted range of times predicted by the model for the end of the bubble is consistent with the observations.

The ISS Biotechnology Facility (BTF) platform provides scientists with a unique opportunity to carry out diverse experiments in a microgravity environment for an extended period of time. Although considerable progress has been made in preserving cells on the ISS for long periods of time for later return to Earth, future biotechnology experiments would desirably monitor, process, and analyze cells in a timely way on-orbit. One aspect of our work has been directed towards developing biochemical sensors for pH, glucose, oxygen, and carbon dioxide for perfused bioreactor system developed at Johnson Space Center. Another aspect is the examination and identification of new and advanced commercial biotechnologies that may have applications to on-orbit experiments.

Biotechnology education as social and cultural production/reproduction of the biotechnology community

Science.gov (United States)

Andrée, Maria

2014-03-01

This paper is a commentary to a paper by Anne Solli, Frank Bach and Björn Åkerman on how students at a technical university learn to argue as biotechnologists. Solli and her colleagues report from an ethnographic study performed during the first semester of a 5-year program in biotechnology at a technical university in Sweden. Their study demonstrates how students begin to acquire `the right way' of approaching the controversial issue of producing and consuming genetically modified organisms. In my response I discuss the ethnographic account of this particular educational practice in terms of social and cultural production/reproduction of a biotechnology community and how the participants (students and teaching professors) deal with the dialectic of individual and collective transformation. In the perspective of the biotechnology community, the work done by the teaching professor becomes a way of ensuring the future of the biotechnology community in terms of what values and objectives are held highly in the community of practice.

Reprint of Design of synthetic microbial communities for biotechnological production processes.

Science.gov (United States)

Jagmann, Nina; Philipp, Bodo

2014-12-20

In their natural habitats microorganisms live in multi-species communities, in which the community members exhibit complex metabolic interactions. In contrast, biotechnological production processes catalyzed by microorganisms are usually carried out with single strains in pure cultures. A number of production processes, however, may be more efficiently catalyzed by the concerted action of microbial communities. This review will give an overview of organismic interactions between microbial cells and of biotechnological applications of microbial communities. It focuses on synthetic microbial communities that consist of microorganisms that have been genetically engineered. Design principles for such synthetic communities will be exemplified based on plausible scenarios for biotechnological production processes. These design principles comprise interspecific metabolic interactions via cross-feeding, regulation by interspecific signaling processes via metabolites and autoinducing signal molecules, and spatial structuring of synthetic microbial communities. In particular, the implementation of metabolic interdependencies, of positive feedback regulation and of inducible cell aggregation and biofilm formation will be outlined. Synthetic microbial communities constitute a viable extension of the biotechnological application of metabolically engineered single strains and enlarge the scope of microbial production processes.

The effect of biotechnology education on Australian high school students' understandings and attitudes about biotechnology processes

Science.gov (United States)

Dawson, Vaille; Soames, Christina

2006-11-01

Our education system aims to equip young people with the knowledge, problem-solving skills and values to cope with an increasingly technological society. The aim of this study was to determine the effect of biotechnology education on adolescents’ understanding and attitudes about processes associated with biotechnology. Data were drawn from teacher and student interviews and surveys in the context of innovative Year 10 biotechnology courses conducted in three Western Australian high schools. The results indicate that after completing a biotechnology course students’ understanding increased but their attitudes remained constant with the exception of their views about human uses of gene technology. The findings of this study have ramifications for the design and implementation of biotechnology education courses in high schools.

Halophiles, coming stars for industrial biotechnology.

Science.gov (United States)

Yin, Jin; Chen, Jin-Chun; Wu, Qiong; Chen, Guo-Qiang

2015-11-15

Industrial biotechnology aims to produce chemicals, materials and biofuels to ease the challenges of shortage on petroleum. However, due to the disadvantages of bioprocesses including energy consuming sterilization, high fresh water consumption, discontinuous fermentation to avoid microbial contamination, highly expensive stainless steel fermentation facilities and competing substrates for human consumption, industrial biotechnology is less competitive compared with chemical processes. Recently, halophiles have shown promises to overcome these shortcomings. Due to their unique halophilic properties, some halophiles are able to grow in high pH and high NaCl containing medium under higher temperature, allowing fermentation processes to run contamination free under unsterile conditions and continuous way. At the same time, genetic manipulation methods have been developed for halophiles. So far, halophiles have been used to produce bioplastics polyhydroxyalkanoates (PHA), ectoines, enzymes, and bio-surfactants. Increasing effects have been made to develop halophiles into a low cost platform for bioprocessing with advantages of low energy, less fresh water consumption, low fixed capital investment, and continuous production.

Why do the biotechnology and the climate change debates hardly mix? Evidence from a global stakeholder survey.

Science.gov (United States)

Aerni, Philipp

2013-05-25

Despite its potential to address climate change problems, the role of biotechnology is hardly ever touched upon in the global sustainability debate. We wanted to know why. For that purpose, we conducted a global online stakeholder survey on biotechnology and climate change. The relevant stakeholders and their representatives were selected by means of key informants that were familiar with either of the two debates. A self-assessment showed that a majority of respondents felt more familiar with the climate change than the biotechnology debate. Even though the survey results reveal that most respondents consider the potential of modern biotechnology to address climate change to be substantial, the policy network analysis revealed that one stakeholder who is not just considered to be relevant in both debates but also crucial in the formation of global public opinion, strongly rejects the view that biotechnology is a climate-friendly and therefore clean technology. This influential opposition seems to ensure that the biotechnology and the climate change debates do not mix. Copyright © 2012 Elsevier B.V. All rights reserved.

Hedge Ratios for short and leveraged ETFs

Directory of Open Access Journals (Sweden)

Leo Schubert

2011-06-01

Full Text Available Exchange Traded Funds (ETFs exist for stock-, bond- and commodity markets. In most cases the underlying of an ETF is an index. Fund management today uses the active and passive way to construct a portfolio. ETFs can be used for passive portfolio management. Then ETFs with positive leverage factors are preferred. In the frame of active portfolio also the ETFs with negative leverage factors can be applied for the hedge or cross hedge of a portfolio. These hedging possibilities will be analyzed in this paper. Short ETFs exist with different leverage factors. In Europe, the leverage factors 1 (e.g. ShortDAX ETF and 2 (e.g. DJ STOXX 600 Double Short are offered while in the financial markets of the United States factors from 1 to 4 can be found. To investigate the effect of the different leverage factors and other parameters Monte Carlo Simulation was used. The results show e.g. that higher leverage factors achieve higher profits as well as losses. In the case, that a bearish market is supposed, minimizing the variance of the hedge seem not to be until to get better hedging results, due to a very skewed return distribution of the hedge. The risk measure target-shortfall-probability confirms the use of the standard hedge weightings which depend only on the leverage factor. This characteristic remains, when a portfolio has to be hedged instead of the underlying index of the short ETF. For portfolios which have a low correlation with the index return should not be used high leverage factors for hedging, due to the higher volatility and target-shortfall-probability.

Photo-biotechnology as a tool to improve agronomic traits in crops.

Science.gov (United States)

Gururani, Mayank Anand; Ganesan, Markkandan; Song, Pill-Soon

2015-01-01

Phytochromes are photosensory phosphoproteins with crucial roles in plant developmental responses to light. Functional studies of individual phytochromes have revealed their distinct roles in the plant's life cycle. Given the importance of phytochromes in key plant developmental processes, genetically manipulating phytochrome expression offers a promising approach to crop improvement. Photo-biotechnology refers to the transgenic expression of phytochrome transgenes or variants of such transgenes. Several studies have indicated that crop cultivars can be improved by modulating the expression of phytochrome genes. The improved traits include enhanced yield, improved grass quality, shade-tolerance, and stress resistance. In this review, we discuss the transgenic expression of phytochrome A and its hyperactive mutant (Ser599Ala-PhyA) in selected crops, such as Zoysia japonica (Japanese lawn grass), Agrostis stolonifera (creeping bentgrass), Oryza sativa (rice), Solanum tuberosum (potato), and Ipomea batatas (sweet potato). The transgenic expression of PhyA and its mutant in various plant species imparts biotechnologically useful traits. Here, we highlight recent advances in the field of photo-biotechnology and review the results of studies in which phytochromes or variants of phytochromes were transgenically expressed in various plant species. We conclude that photo-biotechnology offers an excellent platform for developing crops with improved properties. Copyright © 2014 Elsevier Inc. All rights reserved.

Arnold, Stefanie; Moss, Karin; Henkel, Marius; Hausmann, Rudolf

2017-10-01

Lignocellulosic biomass is an important feedstock for a potential future bio-based economy. Owing to its compact structure, suitable decomposition technologies will be necessary to make it accessible for biotechnological conversion. While chemical and enzymatic hydrolysis are currently established methods, a promising alternative is provided by fast pyrolysis. The main resulting product thereof, referred to as pyrolysis oil, is an energy-rich and easily transportable liquid. Many of the identified constituents of pyrolysis oil, however, have previously been reported to display adverse effects on microbial growth. In this Opinion we discuss relevant biological, biotechnological, and technological challenges that need to be addressed to establish pyrolysis oil as a reliable microbial feedstock for a bio-based economy of the future.

2016-04-01

Full Text Available Aquaculture is gaining commendable importance to meet the required protein source for ever increasing human population. The aquaculture industry is currently facing problems on developing economically viable production systems by reducing the impact on environment. Sustainable and enhanced fish production from aquaculture may be better achieved through application of recent biotechnological innovations. Utilisation of transgenic technology has led to production of fishes with faster growth rate with disease resistance. The full advantage of this technology could not be achieved due to concern of acceptance for Genetically Modified Organisms (GMOs. The biotechnological intervention in developing plant based feed ingredient in place of fish meal which contain high phosphorus is of prime area of attention for fish feed industry. The replacement of fish meal will also reduce fish feed cost to a greater extent. Year round fish seed production of carps through various biotechnological interventions is also need of the hour. This paper discusses technical, environmental and managerial considerations regarding the use of these biotechnological tools in aquaculture along with the advantages of research application and its commercialization.

Biotechnology permits our world to progress. It's a tool to better apprehend the human being, but as well to let him go ahead. Applied to the living, biotechnologies present the same finality. But since their matter concerns effectively the living, they are the sources of specific dangers and particularly of that one to use the improvements obtained on the human to modify the human species. The right of the persons has to find its place to avoid that the fundamental rights of the human personality shall undergo harm. This mission assigned to the right of the persons is as so much invaluable that the economical stakes are particularly important in the domain of the biotechnologies.

Avian Biotechnology.

Nakamura, Yoshiaki

2017-01-01

Primordial germ cells (PGCs) generate new individuals through differentiation, maturation and fertilization. This means that the manipulation of PGCs is directly linked to the manipulation of individuals, making PGCs attractive target cells in the animal biotechnology field. A unique biological property of avian PGCs is that they circulate temporarily in the vasculature during early development, and this allows us to access and manipulate avian germ lines. Following the development of a technique for transplantation, PGCs have become central to avian biotechnology, in contrast to the use of embryo manipulation and subsequent transfer to foster mothers, as in mammalian biotechnology. Today, avian PGC transplantation combined with recent advanced manipulation techniques, including cell purification, cryopreservation, depletion, and long-term culture in vitro, have enabled the establishment of genetically modified poultry lines and ex-situ conservation of poultry genetic resources. This chapter introduces the principles, history, and procedures of producing avian germline chimeras by transplantation of PGCs, and the current status of avian germline modification as well as germplasm cryopreservation. Other fundamental avian reproductive technologies are described, including artificial insemination and embryo culture, and perspectives of industrial applications in agriculture and pharmacy are considered, including poultry productivity improvement, egg modification, disease resistance impairment and poultry gene "pharming" as well as gene banking.

The application of biotechnology is a potential tool for mitigating the present and future fooding and clothing demands in developing countries like India. The commercialization of biotechnological products might benefiting the poor`s in developing countries are unlikely to be developed. Biotechnology has the potential to provide a wide range of products and the existing production skills in the industrial, pharmaceuticals and the agricultural sector. Ownership of the intellectual property rights is the key factors in determining the success of any technological invention, which was introduced in the market. It provides the means for technological progress to continue of the industry of the country. The new plans, animal varieties, new methods of treatments, new crops producing food articles as such are the inventions of biotechnology. Biotechnology is the result of the application of human intelligence and knowledge to the biological processes. Most of the tools of biotechnology have been developed, by companies, governments, research in- stitutes and universities in developed nations. These human intellectual efforts deserve protection. India is a developing country with advance biotechnology based segments of pharmaceutical and agricultural industries. The Trade Related Intellectual Property Rights (TRIPS) is not likely to have a significant impact on incentives for innovation creation in the biotechnology sectors. In the recent years, the world has seen the biotechnology sector as one of greatest investment area through the Patent Law and will giving huge profit in future. The Research and Development in the field of biotechnology should be encouraged for explor- ing new tools and improve the biological systems for interest of the common people. Priority should be given to generation, evaluation, protection and effective commercial utilization of tangible products of intellectual property in agriculture and pharmaceuticals.

Because they mainly do not involve chemical changes, membrane transporters have been a Cinderella subject in the biotechnology of small molecule production, but this is a serious oversight. Influx transporters contribute significantly to the flux towards product, and efflux transporters ensure the accumulation of product in the much greater extracellular space of fermentors. Programmes for improving biotechnological processes might therefore give greater consideration to transporters than may have been commonplace. Strategies for identifying important transporters include expression profiling, genome-wide knockout studies, stress-based selection, and the use of inhibitors. In addition, modern methods of directed evolution and synthetic biology, especially those effecting changes in energy coupling, offer huge opportunities for increasing the flux towards extracellular product formation by transporter engineering.

Re-Framing Biotechnology Regulation.

Science.gov (United States)

Peck, Alison

Biotechnology is about to spill the banks of federal regulation. New genetic engineering techniques like CRISPR-Cas9 promise revolutionary breakthroughs in medicine, agriculture, and public health—but those techniques would not be regulated under the terms of the Coordinated Framework for Regulation of Biotechnology. This revolutionary moment in biotechnology offers an opportunity to correct the flaws in the framework, which was hastily patched together at the advent of the technology. The framework has never captured all relevant technologies, has never satisfied the public that risk is being effectively managed, and has never been accessible to small companies and publicly-funded labs that increasingly are positioned to make radical, life-saving innovations. This Article offers a proposal for new legislation that would reshape biotechnology regulation to better meet these goals. Key reforms include tying regulation to risk rather than technology category; consolidating agency review; capturing distinct regulatory expertise through inter-agency consultations; creating a clearinghouse to help guide applicants and disseminate information; setting up more comprehensive monitoring of environmental effects; and providing federal leadership to fill key data gaps and address socio-economic impacts.

State responses to biotechnology.

Harris, Rebecca C

2015-01-01

This article reviews biotechnology legislation in the 50 states for 11 policy areas spanning 1990-2010, an era of immense growth in biotechnology, genetic knowledge, and significant policy development. Policies regarding health insurance, life insurance, long-term care insurance, DNA data bank collection, biotech research protection, biotech promotion and support, employment discrimination, genetic counselor licensing, human cloning, and genetic privacy each represent major policy responses arising from biotechnology and coinciding with key areas of state regulation (insurance, criminal justice, economic development, labor law, health and safety, privacy, and property rights). This analysis seeks to answer three questions regarding biotechnology legislation at the state level: who is acting (policy adoption), when is policy adopted (policy timing), and what is policy doing (policy content). Theoretical concerns examine state ideology (conservative or liberal), policy type (economic or moral), and the role of external events (federal law, news events, etc.) on state policy adoption. Findings suggest ideological patterns in adoption, timing, and content of biotech policy. Findings also suggest economic policies tend to be more uniform in content than moral policies, and findings also document a clear link between federal policy development, external events, and state policy response.

The diversity and complexity of biotechnological applications are constantly increasing, with ever expanding ranges of production hosts, cultivation conditions and measurement tasks. Consequently, many analytical and cultivation systems for biotechnology and bioprocess engineering, such as microfluidic devices or bioreactors, are tailor-made to precisely satisfy the requirements of specific measurements or cultivation tasks. Additive manufacturing (AM) technologies offer the possibility of fabricating tailor-made 3D laboratory equipment directly from CAD designs with previously inaccessible levels of freedom in terms of structural complexity. This review discusses the historical background of these technologies, their most promising current implementations and the associated workflows, fabrication processes and material specifications, together with some of the major challenges associated with using AM in biotechnology/bioprocess engineering. To illustrate the great potential of AM, selected examples in microfluidic devices, 3D-bioprinting/biofabrication and bioprocess engineering are highlighted. Copyright © 2017 Elsevier B.V.

Societal benefit depends on the general public's understandings of biotechnology (Betsch in World J Microbiol Biotechnol 12:439-443, 1996; Dawson and Cowan in Int J Sci Educ 25(1):57-69, 2003; Schiller in Business Review: Federal Reserve Bank of Philadelphia (Fourth Quarter), 2002; Smith and Emmeluth in Am Biol Teach 64(2):93-99, 2002). A National Science Foundation funded survey of high school biology teachers reported that hands-on biotechnology education exists in advanced high school biology in the United States, but is non-existent in mainstream biology coursework (Micklos et al. in Biotechnology labs in American high schools, 1998). The majority of pre-service teacher content preparation courses do not teach students appropriate content knowledge through the process of inquiry. A broad continuum exists when discussing inquiry-oriented student investigations (Hanegan et al. in School Sci Math J 109(2):110-134, 2009). Depending on the amount of structure in teacher lessons, inquiries can often be categorized as guided or open. The lesson can be further categorized as simple or authentic (Chinn and Malhotra in Sci Educ 86(2):175-218, 2002). Although authentic inquiries provide the best opportunities for cognitive development and scientific reasoning, guided and simple inquiries are more often employed in the classroom (Crawford in J Res Sci Teach 37(9):916-937, 2000; NRC in Inquiry and the national science education standards: a guide for teaching and learning, 2000). For the purposes of this study we defined inquiry as "authentic" if original research problems were resolved (Hanegan et al. in School Sci Math J 109(2):110-134, 2009; Chinn and Malhotra in Sci Educ 86(2):175-218, 2002; Roth in Authentic school science: knowing and learning in open-inquiry science laboratories, 1995). The research question to guide this study through naturalistic inquiry research methods was: How will participants express whether or not an authentic inquiry experience enhanced

Distress risk and leverage puzzles: Evidence from Taiwan

Directory of Open Access Journals (Sweden)

Kung-Cheng Ho

2016-05-01

Full Text Available Financial distress has been invoked in the asset pricing literature to explain the anomalous patterns in the cross-section of stock returns. The risk of financial distress can be measured using indexes. George and Hwang (2010 suggest that leverage can explain the distress risk puzzle and that firms with high costs choose low leverage to reduce distress intensities and earn high returns. This study investigates whether this relationship exists in the Taiwan market. When examined separately, distress intensity is found to be negatively related to stock returns, but leverage is found to not be significantly related to stock returns. The results are the same when distress intensity and leverage are examined simultaneously. After assessing the robustness by using O-scores, distress risk puzzle is found to exist in the Taiwan market, but the leverage puzzle is not

We describe the exciting advances of using optical trapping in the field of analytical biotechnology. This technique has opened up opportunities to manipulate biological particles at the single cell or even at subcellular levels which has allowed an insight into the physical and chemical mechanisms of many biological processes. The ability of this technique to manipulate microparticles and measure pico-Newton forces has found several applications such as understanding the dynamics of biological macromolecules, cell-cell interactions and the micro-rheology of both cells and fluids. Furthermore we may probe and analyse the biological world when combining trapping with analytical techniques such as Raman spectroscopy and imaging. Copyright © 2011 Elsevier Ltd.

The Profits–Leverage Puzzle Revisited

OpenAIRE

Murray Z. Frank; Vidhan K. Goyal

2015-01-01

The inverse relation between leverage and profitability is widely regarded as a serious defect of the trade-off theory. We show that the defect is not with the theory but with the use of a leverage ratio in which profitability affects both the numerator and the denominator. Profitability directly increases the value of equity. Firms do take the predicted offsetting actions. They issue debt and repurchase equity when profitability rises, and retire debt and issue equity when profitability fall...

This empirical fact asserts that past returns are anticorrelated with future diffusion coefficient. Several models with random diffusion have been suggested but without a quantitative study of the leverage effect. Our analysis lets us to fully estimate all parameters involved and allows a deeper study of correlated ...

2017-02-01

Despite substantial focus on sustainability issues in both science and politics, humanity remains on largely unsustainable development trajectories. Partly, this is due to the failure of sustainability science to engage with the root causes of unsustainability. Drawing on ideas by Donella Meadows, we argue that many sustainability interventions target highly tangible, but essentially weak, leverage points (i.e. using interventions that are easy, but have limited potential for transformational change). Thus, there is an urgent need to focus on less obvious but potentially far more powerful areas of intervention. We propose a research agenda inspired by systems thinking that focuses on transformational 'sustainability interventions', centred on three realms of leverage: reconnecting people to nature, restructuring institutions and rethinking how knowledge is created and used in pursuit of sustainability. The notion of leverage points has the potential to act as a boundary object for genuinely transformational sustainability science.

The biochemical engineering and biotechnology is now becoming the most important industry all over the world. China, as a country that has more than 1.3 billion people, has become one of the fastest growing countries in the world during the last several decades. Both the Chinese government and companies pay more and more attention on the research and the application of biotechnology. In the 11th five-year plan (2006-2010), Chinese government unprecedented enhanced the support on the biotechnology in both policy and finance. Currently, the biotechnology gains the most R and D funding in China. With the great support and the increasingly frequent exchanges from abroad, the biotechnology in China becomes more and more important in the world. In recognition of the enormous advances in biotechnology in China, we are pleased to present the second volume of Advances in Biochemical Engineering/ Biotechnology: Biotechnology in China II, edited by P. K. Ouyang, J. Chen and G. T. Tsao, relatively soon after the introduction of the first volume of this multivolume comprehensive books. Since the previous volume was extremely well accepted by the scientific community, we have maintained the overall goal of creating a number of chapters, each devoted to a certain topic by several Chinese research groups working in the field, which provide scientists in academia and public institutions with a well-balanced and comprehensive overview of this growing field in China. We have fully revised the volume and expanded it from bioreaction, bioseparation and bioremediation to more extensive issues in order to cover all recent developments in China into account as much as possible. The new volume of Advances in Biochemical Engineering/Biotechnology: Biotechnology in China II is a comprehensive description of the state-of-the-art in China, and a guide to the understanding the work of Chinese biochemical engineering and biotechnology researchers. It is specifically directed to microbiologists

In comparison with ancient times when everything is handled empirically, biological matter suitable for purposes can be produced and utilized faster and more reliably these days when life science has made a great advance. The advancement is related to new breeding technology and production means, and those means offer the point of contact between biotechnology and agriculture. The application fields of biotechnology are microbiology, cell technology, enzyme technology (bioreactor), and gene engineering. High yield, high content of high value ingredients as foods, adaptability to environment, resistance to disease and insect damage, etc. may be the subjects expected for future agricultural organisms. There may be many areas where biotechnology is related to those organisms, but a discussion is made in this report centering around the problem in breeding. Outlines are given on the applied cases of cell technological method, gene engineering method, and recombinant DNA technology, as well as on gene engineering for plants and animals. 10 refs., 7 figs.

Brief Note on the Development of Biotechnology

Karl Bayer

2014-01-01

Full Text Available Biotechnology, with the main applications in food and nutrition, dates back to the early times of mankind. In the recent decades the progress in natural sciences, mathematics and computer science has led to a new branch termed molecular biotechnology, which finally developed as an autonomous scientific discipline. The field of biotechnology, in the past generally empirically driven, now largely benefits from molecular biotechnology by improved systems, knowledge and understanding. Thereby, compliance with the recently published initiatives of the regulatory authorities to accelerate the approval process for the manufacturing of biopharmaceuticals can be gained.

COPASI is software used for the creation, modification, simulation and computational analysis of kinetic models in various fields. It is open-source, available for all major platforms and provides a user-friendly graphical user interface, but is also controllable via the command line and scripting languages. These are likely reasons for its wide acceptance. We begin this review with a short introduction describing the general approaches and techniques used in computational modeling in the biosciences. Next we introduce the COPASI package, and its capabilities, before looking at typical applications of COPASI in biotechnology. Copyright © 2017 The Authors. Published by Elsevier B.V.

In the present work we address a simple, rapid and quantitative analytical method for detection of different proteins present in biological samples. For this, we proposed the model of titration of double protein (TDP) and its relevant leverage theory relied on the retardation signal of chip moving reaction boundary electrophoresis (MRBE). The leverage principle showed that the product of the first protein content and its absolute retardation signal is equal to that of the second protein content and its absolute one. To manifest the model, we achieved theoretical self-evidence for the demonstration of the leverage principle at first. Then relevant experiments were conducted on the TDP-MRBE chip. The results revealed that (i) there was a leverage principle of retardation signal within the TDP of two pure proteins, and (ii) a lever also existed within these two complex protein samples, evidently demonstrating the validity of TDP model and leverage theory in MRBE chip. It was also showed that the proposed technique could provide a rapid and simple quantitative analysis of two protein samples in a mixture. Finally, we successfully applied the developed technique for the quantification of soymilk in adulterated infant formula. The TDP-MRBE opens up a new window for the detection of adulteration ratio of the poor food (milk) in blended high quality one. Copyright © 2015 Elsevier B.V. All rights reserved.

Biotechnological production of vanillin using immobilized enzymes.

Science.gov (United States)

Furuya, Toshiki; Kuroiwa, Mari; Kino, Kuniki

2017-02-10

Vanillin is an important and popular plant flavor, but the amount of this compound available from plant sources is very limited. Biotechnological methods have high potential for vanillin production as an alternative to extraction from plant sources. Here, we report a new approach using immobilized enzymes for the production of vanillin. The recently discovered oxygenase Cso2 has coenzyme-independent catalytic activity for the conversion of isoeugenol and 4-vinylguaiacol to vanillin. Immobilization of Cso2 on Sepabeads EC-EA anion-exchange carrier conferred enhanced operational stability enabling repetitive use. This immobilized Cso2 catalyst allowed 6.8mg yield of vanillin from isoeugenol through ten reaction cycles at a 1mL scale. The coenzyme-independent decarboxylase Fdc, which has catalytic activity for the conversion of ferulic acid to 4-vinylguaiacol, was also immobilized on Sepabeads EC-EA. We demonstrated that the immobilized Fdc and Cso2 enabled the cascade synthesis of vanillin from ferulic acid via 4-vinylguaiacol with repetitive use of the catalysts. This study is the first example of biotechnological production of vanillin using immobilized enzymes, a process that provides new possibilities for vanillin production. Copyright © 2016 Elsevier B.V.

Cid, Fernanda P; Rilling, Joaquín I; Graether, Steffen P; Bravo, Leon A; Mora, María de La Luz; Jorquera, Milko A

2016-06-01

Ice-binding proteins (IBPs), such as antifreeze proteins (AFPs) and ice-nucleating proteins (INPs), have been described in diverse cold-adapted organisms, and their potential applications in biotechnology have been recognized in various fields. Currently, both IBPs are being applied to biotechnological processes, primarily in medicine and the food industry. However, our knowledge regarding the diversity of bacterial IBPs is limited; few studies have purified and characterized AFPs and INPs from bacteria. Phenotypically verified IBPs have been described in members belonging to Gammaproteobacteria, Actinobacteria and Flavobacteriia classes, whereas putative IBPs have been found in Gammaproteobacteria, Alphaproteobacteria and Bacilli classes. Thus, the main goal of this minireview is to summarize the current information on bacterial IBPs and their application in biotechnology, emphasizing the potential application in less explored fields such as agriculture. Investigations have suggested the use of INP-producing bacteria antagonists and AFPs-producing bacteria (or their AFPs) as a very attractive strategy to prevent frost damages in crops. UniProt database analyses of reported IBPs (phenotypically verified) and putative IBPs also show the limited information available on bacterial IBPs and indicate that major studies are required. © FEMS 2016.

This article develops a model of the interplay between corporate leverage and product differentiation strategy. Leverage improves managerial discipline, but it can also raise customer concerns about a vendor's long-term viability. We argue that customer concerns about firm viability will be particularly pronounced when products are highly differentiated from competitors' products. In this context, optimal product differentiation strategies solve a trade-off between softening price competition...

Next generation industrial biotechnology based on extremophilic bacteria.

Chen, Guo-Qiang; Jiang, Xiao-Ran

2018-04-01

Industrial biotechnology aims to produce bulk chemicals including polymeric materials and biofuels based on bioprocessing sustainable agriculture products such as starch, fatty acids and/or cellulose. However, traditional bioprocesses require bioreactors made of stainless steel, complicated sterilization, difficult and expensive separation procedures as well as well-trained engineers that are able to conduct bioprocessing under sterile conditions, reducing the competitiveness of the bio-products. Amid the continuous low petroleum price, next generation industrial biotechnology (NGIB) allows bioprocessing to be conducted under unsterile (open) conditions using ceramic, cement or plastic bioreactors in a continuous way, it should be an energy, water and substrate saving technology with convenient operation procedure. NGIB also requires less capital investment and reduces demand on highly trained engineers. The foundation for the simplified NGIB is microorganisms that resist contaminations by other microbes, one of the examples is rapid growing halophilic bacteria inoculated under high salt concentration and alkali pH. They have been engineered to produce multiple products in various scales. Copyright © 2017 Elsevier Ltd. All rights reserved.

2017-01-01

This paper examines the leverage effect, or the generally negative covariation between asset returns and their changes in volatility, under a general setup that allows the log-price and volatility processes to be Itô semimartingales. We decompose the leverage effect into continuous and discontinuous parts and develop statistical methods to estimate them. We establish the asymptotic properties of these estimators. We also extend our methods and results (for the continuous leverage) to the situation where there is market microstructure noise in the observed returns. We show in Monte Carlo simulations that our estimators have good finite sample performance. When applying our methods to real data, our empirical results provide convincing evidence of the presence of the two leverage effects, especially the discontinuous one.

Termites as targets and models for biotechnology.

Science.gov (United States)

Scharf, Michael E

2015-01-07

Termites have many unique evolutionary adaptations associated with their eusocial lifestyles. Recent omics research has created a wealth of new information in numerous areas of termite biology (e.g., caste polyphenism, lignocellulose digestion, and microbial symbiosis) with wide-ranging applications in diverse biotechnological niches. Termite biotechnology falls into two categories: (a) termite-targeted biotechnology for pest management purposes, and (b) termite-modeled biotechnology for use in various industrial applications. The first category includes several candidate termiticidal modes of action such as RNA interference, digestive inhibition, pathogen enhancement, antimicrobials, endocrine disruption, and primer pheromone mimicry. In the second category, termite digestomes are deep resources for host and symbiont lignocellulases and other enzymes with applications in a variety of biomass, industrial, and processing applications. Moving forward, one of the most important approaches for accelerating advances in both termite-targeted and termite-modeled biotechnology will be to consider host and symbiont together as a single functional unit.

Vanillin is one of the most important aromatic flavor compounds used in foods, beverages, perfumes, and pharmaceuticals and is produced on a scale of more than 10 thousand tons per year by the industry through chemical synthesis. Alternative biotechnology-based approaches for the production are based on bioconversion of lignin, phenolic stilbenes, isoeugenol, eugenol, ferulic acid, or aromatic amino acids, and on de novo biosynthesis, applying fungi, bacteria, plant cells, or genetically engineered microorganisms. Here, the different biosynthesis routes involved in biotechnological vanillin production are discussed.

The purpose of this review is to survey current, emerging and predicted future biotechnologies which are impacting, or are likely to impact in the future on the life sciences, with a projection for the coming 20 years. This review is intended to discuss current and future technical strategies, and to explore areas of potential growth during the foreseeable future. Information technology approaches have been employed to gather and collate data. Twelve broad categories of biotechnology have been identified which are currently impacting the life sciences and will continue to do so. In some cases, technology areas are being pushed forward by the requirement to deal with contemporary questions such as the need to address the emergence of anti-microbial resistance. In other cases, the biotechnology application is made feasible by advances in allied fields in biophysics (e.g. biosensing) and biochemistry (e.g. bio-imaging). In all cases, the biotechnologies are underpinned by the rapidly advancing fields of information systems, electronic communications and the World Wide Web together with developments in computing power and the capacity to handle extensive biological data. A rationale and narrative is given for the identification of each technology as a growth area. These technologies have been categorized by major applications, and are discussed further. This review highlights: Biotechnology has far-reaching applications which impinge on every aspect of human existence. The applications of biotechnology are currently wide ranging and will become even more diverse in the future. Access to supercomputing facilities and the ability to manipulate large, complex biological datasets, will significantly enhance knowledge and biotechnological development.

Biotechnology: challenges and prospects

Energy Technology Data Exchange (ETDEWEB)

Sasson, A.

1985-04-01

Rapidly occurring technological breakthroughs in the wake of numerous discoveries in different fields, such as biochemistry, genetic engineering as well as cellular and molecular biology as described in this paper have a variety of industrial applications, and forcasts covering these and various other fields have been made. The emerging bio-industry, covering diverse industries, such as chemical, food, pharmaceutical, etc., as well as the domains of health, environmental protection and abatement of pollution present challenging prospects. Several biotechnology processes relating to bioenergy, fermentation, waste transformation, vaccines, etc. are of particular interest to the developing countries. The 'functioning systems' resulting from the breakthrouth in genetic engineering, entailing extraordinary refinement of analytical techniques and technological progress, pose the challenging task of harnessing them to the advantage of mankind. Providing effective legal protection, conducive to the development of biotechnologies-their innovative process and technological change-is a matter of serious concern, involving practical and economical considerations. Several other issues and questions, such as risk prevention and management of potential dangers and hazards in genetic recombination operation by way of safety regulations and necessary guidelines, questions relating to the clinical trials of the interferons-the wonder drug-as well as questions of professional ethics are raised by biotechnologies. Industry-funded research in biotechnology, where scientific and commercial imperatives are interlocked, has for instance, its repercussions on the traditional thrust of university system, specially the sanctity of autonomy for basic research.

Analysis of debt leveraging in private power projects

International Nuclear Information System (INIS)

Kahn, E.P.; Meal, M.; Doerrer, S.; Morse, S.

1992-08-01

As private power (non-utility generation) has grown to become a significant part of the electricity system, increasing concern about its financial implications has arisen. In many cases, the source of this concern has been the substantial reliance of these projects on debt financing. This study examines debt leveraging in private power projects. The policy debate on these issues has typically been conducted at a high level of generality. Critics of the private power industry assert that high debt leveraging confers an unfair competitive advantage by lowering the cost of capital, and that this leveraging is only possible because risks are shifted to the utility. Further, debt leveraging is claimed to be a threat to reliability. On the opposite side, it is argued that debt leveraging imposes costs and obligations not home by utilities, and so there is no financial advantage. The private producers also argue that on balance more risk is shifted away from utilities than to them, and that incentives for reliability are strong. In this study we examine the project finance mechanisms used in private power lending in detail, relying on a sample of actual loan documents. This review and its findings should be relevant to the further evolution of this debate. State regulatory commissions are likely to be interested in it, and Federal legislation to amend the Public Utility Holding Company Act (PUHCA) could require states to consider the implications of debt leveraging in relation to their oversight of utility power purchase programs

Gleim, Savannah; Smyth, Stuart J

2018-05-25

Part of what is presently missing at domestic regulatory levels (and that is important at the international level as well) is a detailed understanding of what the rules of, and for, regulation should be, who the actors, stakeholders and major decision makers are and finally, how to get agreement about the rules. Greater insights into the system of rules that underpin regulatory frameworks for agri-food and biotechnology products in genetically modified (GM) crop- adopting nations will provide value by clarifying the evidence used to commercialize these technologies. This article examines the public documents available from Canada, the United States, the European Union and the Organisation for Economic Cooperation and Development regarding the development of regulatory risk assessment frameworks for products of biotechnology to determine what science grounds these frameworks. The documentation used to provide the initial structure to the existing regulatory frameworks identifies the linkages, connections and relationships that exist between science, risk assessment and regulatory policy. The relationship between risk and regulation has never been more critical to the commercialization of innovative agricultural products. Documenting the role of science-based risk assessment in regulations and how this has changed over the 20 years of experience in regulating GM crops will identify changes in the risk/regulation relationship.

2001-06-01

Pharmaceutical biotechnology is developing rapidly both in academic institutions and in the biopharmaceutical industry. For this reason, FIP Special Interest Group of Pharmaceutical Biotechnology decided to develop a questionnaire concerning pharmaceutical biotechnology education. After preliminary studies were completed, questionnaires were sent to the leading scientists in academia and research directors or senior managers of various Pharmaceutical Biotechnology Companies in order to gather their views about how to create a satisfactory program. The objectives of this study were as follows: -To review all of the graduate and undergraduate courses which are presently available worldwide on pharmaceutical biotechnology in Faculties of Pharmacy. -To review all of the text books, references and scientific sources available worldwide in the area of pharmaceutical biotechnology. When replying to the questionnaires, the respondents were asked to consider the present status of pharmaceutical biotechnology education in academia and future learning needs in collaboration with the biotechnology industry. The data from various pharmacy faculties and biotechnology industry representatives from Asia, Europe and America were evaluated and the outcome of the survey showed that educational efforts in training qualified staff in the rapidly growing field of pharmaceutical biotechnology is promising. Part of the results of this questionnaire study have already been presented at the 57th International Congress of FIP Vancouver, Canada in 1997.

Challenges and opportunities for improving food quality and nutrition through plant biotechnology.

Science.gov (United States)

Francis, David; Finer, John J; Grotewold, Erich

2017-04-01

Plant biotechnology has been around since the advent of humankind, resulting in tremendous improvements in plant cultivation through crop domestication, breeding and selection. The emergence of transgenic approaches involving the introduction of defined DNA sequences into plants by humans has rapidly changed the surface of our planet by further expanding the gene pool used by plant breeders for plant improvement. Transgenic approaches in food plants have raised concerns on the merits, social implications, ecological risks and true benefits of plant biotechnology. The recently acquired ability to precisely edit plant genomes by modifying native genes without introducing new genetic material offers new opportunities to rapidly exploit natural variation, create new variation and incorporate changes with the goal to generate more productive and nutritious plants.

Contemporary molecular tools in microbial ecology and their application to advancing biotechnology.

Science.gov (United States)

Rashid, Mamoon; Stingl, Ulrich

2015-12-01

Novel methods in microbial ecology are revolutionizing our understanding of the structure and function of microbes in the environment, but concomitant advances in applications of these tools to biotechnology are mostly lagging behind. After more than a century of efforts to improve microbial culturing techniques, about 70-80% of microbial diversity - recently called the "microbial dark matter" - remains uncultured. In early attempts to identify and sample these so far uncultured taxonomic lineages, methods that amplify and sequence ribosomal RNA genes were extensively used. Recent developments in cell separation techniques, DNA amplification, and high-throughput DNA sequencing platforms have now made the discovery of genes/genomes of uncultured microorganisms from different environments possible through the use of metagenomic techniques and single-cell genomics. When used synergistically, these metagenomic and single-cell techniques create a powerful tool to study microbial diversity. These genomics techniques have already been successfully exploited to identify sources for i) novel enzymes or natural products for biotechnology applications, ii) novel genes from extremophiles, and iii) whole genomes or operons from uncultured microbes. More can be done to utilize these tools more efficiently in biotechnology. Copyright © 2015 Elsevier Inc. All rights reserved.

Electronic health records (EHRs) can be a major tool in the quest to decrease costs and timelines of clinical trial research, generate better evidence for clinical decision making, and advance health care. Over the past decade, EHRs have increasingly offered opportunities to speed up, streamline, and enhance clinical research. EHRs offer a wide range of possible uses in clinical trials, including assisting with prestudy feasibility assessment, patient recruitment, and data capture in care delivery. To fully appreciate these opportunities, health care stakeholders must come together to face critical challenges in leveraging EHR data, including data quality/completeness, information security, stakeholder engagement, and increasing the scale of research infrastructure and related governance. Leaders from academia, government, industry, and professional societies representing patient, provider, researcher, industry, and regulator perspectives convened the Leveraging EHR for Clinical Research Now! Think Tank in Washington, DC (February 18-19, 2016), to identify barriers to using EHRs in clinical research and to generate potential solutions. Think tank members identified a broad range of issues surrounding the use of EHRs in research and proposed a variety of solutions. Recognizing the challenges, the participants identified the urgent need to look more deeply at previous efforts to use these data, share lessons learned, and develop a multidisciplinary agenda for best practices for using EHRs in clinical research. We report the proceedings from this think tank meeting in the following paper. Copyright © 2018 Elsevier, Inc. All rights reserved.

Biotechnology and Consumer Decision-Making.

Science.gov (United States)

Sax, Joanna K

Society is facing major challenges in climate change, health care and overall quality of life. Scientific advances to address these areas continue to grow, with overwhelming evidence that the application of highly tested forms of biotechnology is safe and effective. Despite scientific consensus in these areas, consumers appear reluctant to support their use. Research that helps to understand consumer decision-making and the public’s resistance to biotechnologies such as vaccines, fluoridated water programs and genetically engineered food, will provide great social value. This article is forward-thinking in that it suggests that important research in behavioral decision-making, specifically affect and ambiguity, can be used to help consumers make informed choices about major applications of biotechnology. This article highlights some of the most controversial examples: vaccinations, genetically engineered food, rbST treated dairy cows, fluoridated water, and embryonic stem cell research. In many of these areas, consumers perceive the risks as high, but the experts calculate the risks as low. Four major thematic approaches are proposed to create a roadmap for policymakers to consider for policy design and implementation in controversial areas of biotechnology. This article articulates future directions for studies that implement decision-making research to allow consumers to appropriately assign risk to their options and make informed decisions.

Abu Bakar, Umi K; Pillai, Vilasini; Hashim, Marzukhi; Daud, Hassan Mat

2005-12-01

Biotechnology-derived food crops are currently being developed in Malaysia mainly for disease resistance and improved post harvest quality. The modern biotechnology approach is adopted because of its potential to overcome constraints faced by conventional breeding techniques. Research on the development of biotechnology-derived papaya, pineapple, chili, passion fruit, and citrus is currently under way. Biotechnology-derived papaya developed for resistance to papaya ringspot virus (PRSV) and improved postharvest qualities is at the field evaluation stage. Pineapple developed for resistance to fruit black heart disorder is also being evaluated for proof-of-concept. Other biotechnology-derived food crops are at early stages of gene cloning and transformation. Activities and products involving biotechnology-derived crops will be fully regulated in the near future under the Malaysian Biosafety Law. At present they are governed only by guidelines formulated by the Genetic Modification Advisory Committee (GMAC), Malaysia. Commercialization of biotechnology-derived crops involves steps that require GMAC approval for all field evaluations and food-safety assessments before the products are placed on the market. Public acceptance of the biotechnology product is another important factor for successful commercialization. Understanding of biotechnology is generally low among Malaysians, which may lead to low acceptance of biotechnology-derived products. Initiatives are being taken by local organizations to improve public awareness and acceptance of biotechnology. Future research on plant biotechnology will focus on the development of nutritionally enhanced biotechnology-derived food crops that can provide more benefits to consumers.

Recent Advances in Marine Enzymes for Biotechnological Processes.

Science.gov (United States)

Lima, R N; Porto, A L M

In the last decade, new trends in the food and pharmaceutical industries have increased concern for the quality and safety of products. The use of biocatalytic processes using marine enzymes has become an important and useful natural product for biotechnological applications. Bioprocesses using biocatalysts like marine enzymes (fungi, bacteria, plants, animals, algae, etc.) offer hyperthermostability, salt tolerance, barophilicity, cold adaptability, chemoselectivity, regioselectivity, and stereoselectivity. Currently, enzymatic methods are used to produce a large variety of products that humans consume, and the specific nature of the enzymes including processing under mild pH and temperature conditions result in fewer unwanted side-effects and by-products. This offers high selectivity in industrial processes. The marine habitat has been become increasingly studied because it represents a huge source potential biocatalysts. Enzymes include oxidoreductases, hydrolases, transferases, isomerases, ligases, and lyases that can be used in food and pharmaceutical applications. Finally, recent advances in biotechnological processes using enzymes of marine organisms (bacterial, fungi, algal, and sponges) are described and also our work on marine organisms from South America, especially marine-derived fungi and bacteria involved in biotransformations and biodegradation of organic compounds. © 2016 Elsevier Inc.

A simple analytical model for dynamics of time-varying target leverage ratios

Science.gov (United States)

Lo, C. F.; Hui, C. H.

2012-03-01

In this paper we have formulated a simple theoretical model for the dynamics of the time-varying target leverage ratio of a firm under some assumptions based upon empirical observations. In our theoretical model the time evolution of the target leverage ratio of a firm can be derived self-consistently from a set of coupled Ito's stochastic differential equations governing the leverage ratios of an ensemble of firms by the nonlinear Fokker-Planck equation approach. The theoretically derived time paths of the target leverage ratio bear great resemblance to those used in the time-dependent stationary-leverage (TDSL) model [Hui et al., Int. Rev. Financ. Analy. 15, 220 (2006)]. Thus, our simple model is able to provide a theoretical foundation for the selected time paths of the target leverage ratio in the TDSL model. We also examine how the pace of the adjustment of a firm's target ratio, the volatility of the leverage ratio and the current leverage ratio affect the dynamics of the time-varying target leverage ratio. Hence, with the proposed dynamics of the time-dependent target leverage ratio, the TDSL model can be readily applied to generate the default probabilities of individual firms and to assess the default risk of the firms.

Biotechnology's foreign policy.

Science.gov (United States)

Feldbaum, Carl

2002-01-01

From its inception, biotechnology has been a uniquely international enterprise. An American and an Englishman working together elucidated the structure of DNA almost 50 years ago; more recently, the Human Genome Project linked researchers around the world, from the Baylor College of Medicine in Houston to the Beijing Human Genome Center. Today our industry's researchers hail from African villages and Manhattan high rises; from Munich and Melbourne; from London, Ontario, and London, England; from Scotland and Nova Scotia--New Scotland; from Calcutta and Calgary. But in the beginning, the infrastructure that supported these efforts--intellectual property, venture capital, streamlined technology transfer--was less widely dispersed and the world's brightest biotech researchers clustered in only half a dozen scientific Meccas. Previous technological revolutions have spread around the world. Following in their footsteps, biotechnology's global diaspora seems inevitable, especially since governments are promoting it. But as our science and business emigrate from early strongholds in the United States, Canada and Europe across oceans and borders and into new cultures, international tensions over biotechnology continue to grow. In just the last few years, controversies have rolled over R&D spending priorities, genetic patents, bioprospecting, transgenic agriculture and drug pricing. My premise today is that our industry needs to formulate its first foreign policy, one which is cognizant of the miserable judgments and mistakes of other industries--and avoids them.

We show that a firm's ability to reap growth opportunities from R&D investments depends on its size, leverage, and the industry concentration. While the direct effects of these factors are significant, the size-leverage interaction reveals further important insights. Large firms' advantages over small firms disappear as their leverage increases. Specifically, small firms with high leverage reap the greatest growth opportunities. Our results provide explanations for inconsistent findings obser...

Medical Biotechnology: Problems and Prospects in Bangladesh

Directory of Open Access Journals (Sweden)

Shaikh Mizan

2013-01-01

Full Text Available Biotechnology is the knowledge and techniques of developing and using biological systems for deriving special products and services. The age-old technology took a new turn with the advent of recombinant DNA techniques, and boosted by the development of other molecular biological techniques, cell culture techniques and bioinformatics. Medical biotechnology is the major thrust area of biotechnology. It has brought revolutions in medicine – quick methods for diagnosing diseases, generation of new drugs and vaccines, completely novel approach of treatment are only a few to mention. The industrial and financial bulk of the industry mushroomed very rapidly in the last three decades, led by the USA and western advanced nations. Asian countries like China, India, South Korea, Taiwan and Singapore joined late, but advancing forward in a big way. In all the Asian countries governments supported the initiatives of the expert and entrepreneur community, and invested heavily in its development. Bangladesh has got great potential in developing biotechnology and reaping its fruits. However, lack of commitment and patriotism, and too much corruption and irresponsibility in political and bureaucratic establishment are the major hindrance to the development of biotechnology in Bangladesh.

Heterotrophic bacteria are an integral part of any environmental biotechnology process (EBP). Therefore, factors controlling bacterial abundance, activity, and community composition are central to the understanding of such processes. Among these factors, top-down control by bacteriophage predation has so far received very limited attention. With over 10(8) particles per ml, phage appear to be the most numerous biological entities in EBP. Phage populations in EBP appear to be highly dynamic and to correlate with the population dynamics of their hosts and genomic evidence suggests bacteria evolve to avoid phage predation. Clearly, there is much to learn regarding bacteriophage in EBP before we can truly understand the microbial ecology of these globally important systems. Copyright © 2011 Elsevier Ltd.

Biotechnology could provide many innovative alternatives for changing the way metals are obtained. Microbes have been used to dissolve metallic minerals and release metal ions into solution, from which pure metal can be obtained by electrolysis. Plants that accumulate metals in their roots and leaves have been used to concentrate metals, and mineral-binding peptides might be used to separate minerals. However, for billions of years microbes have been interacting with metals. Microbial communities in and near mineral sources are therefore a rich source of genetic information which could be used to create synthetic or modified microbiomes that concentrate metals. This would be a complete paradigm-change with enormous scope for transforming the way metals are obtained. Copyright © 2016 Elsevier Ltd. All rights reserved.

2008-01-01

The results of collaborative work carried out in the field of biotechnology at the Frank Laboratory of Neutron Physics (FLNP) of the Joint Institute for Nuclear Research (JINR) (Dubna, Russia) jointly with scientists from Georgia are presented. Using instrumental neutron activation analysis (NAA), significant results were ontained in the following directions - medical biotechnology, environmental biotechnology and industrial biotechnology. In the biomedical experiments a blue-green alga Spirulina platensis biomass has been used as a matrix for the development of pharmaceutical substances containing such vitally important trace elements as selenium, chromium and iodine. The feasibility of target-oriented introduction of these elements into Spirulina platensis biocomplexes retaining its protain composition and natural beneficial properties has been proved. The adsorption of such toxic metal as mercury by Spirulina platensis biomass in dynamics of growth has been studied also. NAA has been successfully applied to investigate the biotechnology of toxic Cr(VI) transformation into less toxic Cr(III) complexes by Cr(VI)-reducer bacteria isolated from polluted basalts in Georgia. This method was used to track accumulation of chromium in the bacterial cells. To monitor and identify Cr(III) complexes in these bacteria, electron spin resonance (ESR) spectrometry was employed. For the first time, the elemental composition of Cr(VI)-reducer bacteria has been studied using epithermal NAA. The natural organic mass of vegetal origin - peat - was applied as a source of microorganisms to study the bacterial leaching of some metals from lean ores, rocks and industrial wastes. (author)

Full Text Available The development of molecular biology and molecular genetics, especially of the recombinant DNA technology enabled improvement of experimental methods that provide manipulation within a cell-free system, such as cell and tissue cultures. Such methods resulted in the development of different new technologies with specific properties in relation to the conventional definitions. According to PERSLEY and lantin (2000 the following components are essential for the contemporary biotechnology: (i genomics - a molecular characterization of all genes and gene products of an organism (ii bioinformatics - the assembly of data from genomic analysis into accessible forms; (iii transformation - the introduction of genes controlling a trait of interest into a genome of a desired organism (micro organisms, plants, animal systems. By the application of cotemporary biotechnology new methods in the field of diagnostic are developed such as rapid and more accurate identification of the presence and absence of genes in the genome of the organism of interest (identification of pathogens prenatal diagnostics, molecular markers assisted breeding for plants, etc. The traits of an organism are determined by its genetic material, i.e. by a molecule of deoxyribonucleic acid (DNA. watson and crick (1953 were the first scientists to describe the structure of DNA as a double-stranded helix. Higher organisms contain a set of linear DNA molecules - chromosomes and a full set of chromosomes of an organism is a genome. Each genome is divided into a series of functional units, i.e. genes. The traits of an organism depend on genes, but their expression depends not only on genes but also on many other factors, including whether a gene, controlling the trait, expresses, specific cells in which it expresses and specially the mode by which the gene and its product interact with the environment. A special aspect within the application of biotechnology occurs as an interaction of a

Biotechnology in maize breeding

2004-01-01

Full Text Available Maize is one of the most important economic crops and the best studied and most tractable genetic system among monocots. The development of biotechnology has led to a great increase in our knowledge of maize genetics and understanding of the structure and behaviour of maize genomes. Conventional breeding practices can now be complemented by a number of new and powerful techniques. Some of these often referred to as molecular methods, enable scientists to see the layout of the entire genome of any organism and to select plants with preferred characteristics by "reading" at the molecular level, saving precious time and resources. DNA markers have provided valuable tools in various analyses ranging from phylogenetic analysis to the positional cloning of genes. Application of molecular markers for genetic studies of maize include: assessment of genetic variability and characterization of germ plasm, identification and fingerprinting of genotypes, estimation of genetic distance, detection of monogamic and quantitative trait loci, marker assisted selection, identification of sequence of useful candidate genes, etc. The development of high-density molecular maps which has been facilitated by PCR-based markers, have made the mapping and tagging of almost any trait possible and serve as bases for marker assisted selection. Sequencing of maize genomes would help to elucidate gene function, gene regulation and their expression. Modern biotechnology also includes an array of tools for introducing or deieting a particular gene or genes to produce plants with novel traits. Development of informatics and biotechnology are resulted in bioinformatic as well as in expansion of microarrey technique. Modern biotechnologies could complement and improve the efficiency of traditional selection and breeding techniques to enhance agricultural productivity.

White biotechnology: State of the art strategies for the development of biocatalysts for biorefining.

Science.gov (United States)

Heux, S; Meynial-Salles, I; O'Donohue, M J; Dumon, C

2015-12-01

White biotechnology is a term that is now often used to describe the implementation of biotechnology in the industrial sphere. Biocatalysts (enzymes and microorganisms) are the key tools of white biotechnology, which is considered to be one of the key technological drivers for the growing bioeconomy. Biocatalysts are already present in sectors such as the chemical and agro-food industries, and are used to manufacture products as diverse as antibiotics, paper pulp, bread or advanced polymers. This review proposes an original and global overview of highly complementary fields of biotechnology at both enzyme and microorganism level. A certain number of state of the art approaches that are now being used to improve the industrial fitness of biocatalysts particularly focused on the biorefinery sector are presented. The first part deals with the technologies that underpin the development of industrial biocatalysts, notably the discovery of new enzymes and enzyme improvement using directed evolution techniques. The second part describes the toolbox available by the cell engineer to shape the metabolism of microorganisms. And finally the last part focuses on the 'omic' technologies that are vital for understanding and guide microbial engineering toward more efficient microbial biocatalysts. Altogether, these techniques and strategies will undoubtedly help to achieve the challenging task of developing consolidated bioprocessing (i.e. CBP) readily available for industrial purpose.

Schiraldi, Chiara; Giuliano, Mariateresa; De Rosa, Mario

2002-01-01

Many archaea colonize extreme environments. They include hyperthermophiles, sulfur-metabolizing thermophiles, extreme halophiles and methanogens. Because extremophilic microorganisms have unusual properties, they are a potentially valuable resource in the development of novel biotechnological processes. Despite extensive research, however, there are few existing industrial applications of either archaeal biomass or archaeal enzymes. This review summarizes current knowledge about the biotechnological uses of archaea and archaeal enzymes with special attention to potential applications that are the subject of current experimental evaluation. Topics covered include cultivation methods, recent achievements in genomics, which are of key importance for the development of new biotechnological tools, and the application of wild-type biomasses, engineered microorganisms, enzymes and specific metabolites in particular bioprocesses of industrial interest.

A bibliometric assessment of ASEAN collaboration in plant biotechnology

KAUST Repository

Payumo, Jane

2015-04-03

This study draws on publication and citation data related to plant biotechnology from a 10-year (2004–2013) period to assess the research performance, impact, and collaboration of member states of the Association of Southeast Asian Nations (ASEAN). Plant biotechnology is one of the main areas of cooperation between ASEAN member states and among the research areas promoted to achieve regional food security and sustainable development. In general, findings indicate increased scientific output, influence, and overall collaboration of ASEAN countries in plant biotechnology over time. Research performance and collaboration (domestic, regional, and international) of the region in plant biotechnology are linked to the status of the economic development of each member country. Thailand produced the most publications of the ASEAN member states while Singapore had the highest influence as indicated by its citation activity in plant biotechnology among the ASEAN countries. Domestic and international collaborations on plant biotechnology are numerous. Regional collaboration or partnership among ASEAN countries was, however, was found to be very limited, which is a concern for the region’s goal of economic integration and science and technology cooperation. More studies using bibliometric data analysis need to be conducted to understand plant biotechnology cooperation and knowledge flows between ASEAN countries. © 2015 Akadémiai Kiadó, Budapest, Hungary

Filamentous fungal secretomes comprise highly dynamic sets of proteins, including multiple carbohydrate active enzymes (CAZymes) which are able to hydrolyze plant biomass polysaccharides into products of biotechnological interest such as fermentable sugars. In recent years, proteomics has been used to identify and quantify enzymatic and non-enzymatic polypeptides present in secretomes of several fungi species. The resulting data have widened the scientific understanding of the way filamentous fungi perform biomass degradation and offered novel perspectives for biotechnological applications. The present review discusses proteomics approaches that have been applied to the study of fungal secretomes, focusing on two of the most studied filamentous fungi genera: Trichoderma and Aspergillus.

Proteomics: A Biotechnology Tool for Crop Improvement

Directory of Open Access Journals (Sweden)

Moustafa eEldakak

2013-02-01

Full Text Available A sharp decline in the availability of arable land and sufficient supply of irrigation water along with a continuous steep increase in food demands have exerted a pressure on farmers to produce more with fewer resources. A viable solution to release this pressure is to speed up the plant breeding process by employing biotechnology in breeding programs. The majority of biotechnological applications rely on information generated from various -omic technologies. The latest outstanding improvements in proteomic platforms and many other but related advances in plant biotechnology techniques offer various new ways to encourage the usage of these technologies by plant scientists for crop improvement programs. A combinatorial approach of accelerated gene discovery through genomics, proteomics, and other associated -omic branches of biotechnology, as an applied approach, is proving to be an effective way to speed up the crop improvement programs worldwide. In the near future, swift improvements in -omic databases are becoming critical and demand immediate attention for the effective utilization of these techniques to produce next-generation crops for the progressive farmers. Here, we have reviewed the recent advances in proteomics, as tools of biotechnology, which are offering great promise and leading the path towards crop improvement for sustainable agriculture.

Industrial use of Biotechnology in Agriculture

But, S.J.

2006-01-01

In the past the biological research was restricted within the boundary of laboratories and the subsequent results were often employed merely to strengthen the research knowledge and information. In life sciences, the traditional methods took years in proving the biological facts. At the leg of last century, the practical application of biotechnology provided a powerful tool to mankind that has led to a revolutionary change in modern agriculture. In the present era, the economy of agro-based countries all over the world is dependent on the adaptation of the pattern of crop-production and their improvement through modern biotechnological means. Biotechnology is in fact the name of a combination of techniques involved to make the full use of living organisms, either in total or in part, for the benefit of plants, animals or human beings. Progressive and dynamic investors, associated with researches/scientists, should be encouraged to step forward for the mobilization of emerging trend of biotechnological industry in agriculture. Researcher/Scientists of biological programmes in Pakistan should be encouraged at Government level to come forward in contributing their tremendous role to boost Agr- industry in the country.

THE IMPACT OF FINANCIAL LEVERAGE ON RETURN AND RISK

Directory of Open Access Journals (Sweden)

HAKAN SARITAŞ

2013-05-01

Full Text Available Financing with debt and preferred stock to increase the potential return to the residual common shareholders’ equity is referred to as financial leverage. A firm’s return on equity (ROE is a key determinant of the growth rate of its earnings. Return on equity is affected profoundly by the firm’s degree of financial leverage. Increased debt will make a positive contribution to a firm’s ROE only if the firm’s return on assets (ROA exceeds the interest rate on the debt. In spite of the fact that financial leverage increases the rate of return on common stock equity, the grater the proportion of debt in the capital structure, however, the greater the risk the common shareholders bear. Introduction of financial leverage increases the average profitability of the firm as well as its risk. In good economic years, the impact of financial leverage will most likely be positive; however, the leverage effect may be negative in relatively bad years. Traditionally, studies treated short-term debt and long-term debt as perfect substitutes for each other. There is, however, risk-sharing by long-term debtholders which makes short-term debt financing riskier to shareholders than long-term debt financing. The significant affect associated with the total debt usage is largely attributable to short-term debt financing, since the impact of short-term debt financing on the expected returns is shown to be greater than that of long-term debt financing.

Biotechnology of non-Saccharomyces yeasts-the basidiomycetes.

Science.gov (United States)

Johnson, Eric A

2013-09-01

Yeasts are the major producer of biotechnology products worldwide, exceeding production in capacity and economic revenues of other groups of industrial microorganisms. Yeasts have wide-ranging fundamental and industrial importance in scientific, food, medical, and agricultural disciplines (Fig. 1). Saccharomyces is the most important genus of yeast from fundamental and applied perspectives and has been expansively studied. Non-Saccharomyces yeasts (non-conventional yeasts) including members of the Ascomycetes and Basidiomycetes also have substantial current utility and potential applicability in biotechnology. In an earlier mini-review, "Biotechnology of non-Saccharomyces yeasts-the ascomycetes" (Johnson Appl Microb Biotechnol 97: 503-517, 2013), the extensive biotechnological utility and potential of ascomycetous yeasts are described. Ascomycetous yeasts are particularly important in food and ethanol formation, production of single-cell protein, feeds and fodder, heterologous production of proteins and enzymes, and as model and fundamental organisms for the delineation of genes and their function in mammalian and human metabolism and disease processes. In contrast, the roles of basidiomycetous yeasts in biotechnology have mainly been evaluated only in the past few decades and compared to the ascomycetous yeasts and currently have limited industrial utility. From a biotechnology perspective, the basidiomycetous yeasts are known mainly for the production of enzymes used in pharmaceutical and chemical synthesis, for production of certain classes of primary and secondary metabolites such as terpenoids and carotenoids, for aerobic catabolism of complex carbon sources, and for bioremediation of environmental pollutants and xenotoxicants. Notwithstanding, the basidiomycetous yeasts appear to have considerable potential in biotechnology owing to their catabolic utilities, formation of enzymes acting on recalcitrant substrates, and through the production of unique primary

Some like it hot, some like it cold: Temperature dependent biotechnological applications and improvements in extremophilic enzymes.

Siddiqui, Khawar Sohail

2015-12-01

The full biotechnological exploitation of enzymes is still hampered by their low activity, low stability and high cost. Temperature-dependent catalytic properties of enzymes are a key to efficient and cost-effective translation to commercial applications. Organisms adapted to temperature extremes are a rich source of enzymes with broad ranging thermal properties which, if isolated, characterized and their structure-function-stability relationship elucidated, could underpin a variety of technologies. Enzymes from thermally-adapted organisms such as psychrophiles (low-temperature) and thermophiles (high-temperature) are a vast natural resource that is already under scrutiny for their biotechnological potential. However, psychrophilic and thermophilic enzymes show an activity-stability trade-off that necessitates the use of various genetic and chemical modifications to further improve their properties to suit various industrial applications. This review describes in detail the properties and biotechnological applications of both cold-adapted and thermophilic enzymes. Furthermore, the review critically examines ways to improve their value for biotechnology, concluding by proposing an integrated approach involving thermally-adapted, genetically and magnetically modified enzymes to make biocatalysis more efficient and cost-effective.

Macroeconomic Dynamics of Assets, Leverage and Trust

Science.gov (United States)

Rozendaal, Jeroen C.; Malevergne, Yannick; Sornette, Didier

A macroeconomic model based on the economic variables (i) assets, (ii) leverage (defined as debt over asset) and (iii) trust (defined as the maximum sustainable leverage) is proposed to investigate the role of credit in the dynamics of economic growth, and how credit may be associated with both economic performance and confidence. Our first notable finding is the mechanism of reward/penalty associated with patience, as quantified by the return on assets. In regular economies where the EBITA/Assets ratio is larger than the cost of debt, starting with a trust higher than leverage results in the highest long-term return on assets (which can be seen as a proxy for economic growth). Therefore, patient economies that first build trust and then increase leverage are positively rewarded. Our second main finding concerns a recommendation for the reaction of a central bank to an external shock that affects negatively the economic growth. We find that late policy intervention in the model economy results in the highest long-term return on assets. However, this comes at the cost of suffering longer from the crisis until the intervention occurs. The phenomenon that late intervention is most effective to attain a high long-term return on assets can be ascribed to the fact that postponing intervention allows trust to increase first, and it is most effective to intervene when trust is high. These results are derived from two fundamental assumptions underlying our model: (a) trust tends to increase when it is above leverage; (b) economic agents learn optimally to adjust debt for a given level of trust and amount of assets. Using a Markov Switching Model for the EBITA/Assets ratio, we have successfully calibrated our model to the empirical data of the return on equity of the EURO STOXX 50 for the time period 2000-2013. We find that dynamics of leverage and trust can be highly nonmonotonous with curved trajectories, as a result of the nonlinear coupling between the variables. This

Electron shuttles in biotechnology.

Science.gov (United States)

Watanabe, Kazuya; Manefield, Mike; Lee, Matthew; Kouzuma, Atsushi

2009-12-01

Electron-shuttling compounds (electron shuttles [ESs], or redox mediators) are essential components in intracellular electron transfer, while microbes also utilize self-produced and naturally present ESs for extracellular electron transfer. These compounds assist in microbial energy metabolism by facilitating electron transfer between microbes, from electron-donating substances to microbes, and/or from microbes to electron-accepting substances. Artificially supplemented ESs can create new routes of electron flow in the microbial energy metabolism, thereby opening up new possibilities for the application of microbes to biotechnology processes. Typical examples of such processes include halogenated-organics bioremediation, azo-dye decolorization, and microbial fuel cells. Herein we suggest that ESs can be applied widely to create new microbial biotechnology processes.

Abu-Ghosh, Said; Fixler, Dror; Dubinsky, Zvy; Iluz, David

2016-03-01

Flashing light can enhance photosynthesis and improve the quality and quantity of microalgal biomass, as it can increase the products of interest by magnitudes. Therefore, the integration of flashing light effect into microalgal cultivation systems should be considered. However, microalgae require a balanced mix of the light/dark cycle for higher growth rates, and respond to light intensity differently according to the pigments acquired or lost during the growth. This review highlights recently published results on flashing light effect on microalgae and its applications in biotechnology, as well as the recently developed bioreactors designed to fulfill this effect. It also discusses how this knowledge can be applied in selecting the optimal light frequencies and intensities with specific technical properties for increasing biomass production and/or the yield of the chemicals of interest by microalgae belonging to different genera.

production and the economy of this depressed areas. However, the problems bound to environmental protection must not be forgotten; priority should be given to monitor the risks of introduction of foreign species. Red biotechnologies potentially bring a vast domain of powerful tools and processes to achieve better human health, most notably improved diagnostics by molecular techniques, better targeting of pathogens and a better knowledge of their sensitivities to drugs to permit better treatment. Biosafety regulatory frameworks had been initiated in several countries, starting with primary biosafety law. However, disparate attitudes to the purpose of biosafety regulation (e.g., fostering informed decision-making versus 'giving the green-light for a flood of GMOs') currently prevent a needed consensus for sub-regional harmonisation. To date, most R&D funding has come from North America with some commercial interests from Asia, but African biotechnology workers expressed strong desire for (re-)engagement with interested parties from the European Union. Although in some of the visited countries there are very well qualified personnel in molecular biology and biosafety/regulation, the main message received is that human resources and capacity building in-house are still needed. This could be achieved through home-based courses and capacity-building including funds for post-degree research to motivate and retain trained staff. Copyright © 2011 Elsevier B.V.

Oil and biotechnology

Energy Technology Data Exchange (ETDEWEB)

Yasui, Yoshiaki

1988-06-01

The secondary oil recovery due to microorganisms and the production of useful substances from oil distillates using microorganisms are described as examples to solidify the relationship between oil and biotechnology. The secondary crude-oil recovery has been carried out due to the microorganism drive process, which includes the on-the-ground and underground processes. Although the microorganism drive process has been investigated for many years, the selection of the microorganisms is not completely established. Many uncertainties still remain regarding the technical and economic aspects. The single cell protein (SCP) is an example of industrial success in the production of useful substances from the oil. Rumania has produced SCP from normal paraffin and the U. K. from the methanol and the products are used as the protein source for animals. Remarkable progress in the functional efficiency of microorganisms is expected due to the biotechnology for both applications. (4 tabs)

[Health risks in the biotechnological industry].

Science.gov (United States)

Colombi, A; Maroni, M; Foà, V

1989-01-01

Biotechnology has been defined as the application of biological organisms, systems or processes to manufacturing and service industries. In considering health aspects of biotechnological development it must be underlined that the use of microorganisms in traditional industries, such as the production of food, bread, beer and dairy products, has not added significantly to the more usual industrial hazards. The risk factors encountered in the biotechnology industry can be defined as general, i.e., common to other industrial activities, and specific, i.e., depending on the presence of microorganisms and/or their metabolic products. The specific health risks vary according to the type of process, but can be grouped into three main categories: immunological diseases, toxic effects; pathological effects of microorganisms. Allergic immunological diseases such as bronchial asthma, contact dermatitis, oculo-rhinitis and extrinsic allergic alveolitis are by far the most frequent and well known diseases occurring among workers employed on biotechnological production. Toxic effects were observed among workers employed on the production of antibiotics and hormones or single cell proteins, where absorption of endotoxins has been described. Infectious diseases may arise from uncontrolled dissemination of pathogenic microorganisms through aerosols, dusts, aqueous and semisolid sludge effluents from biotechnological plants. The greatest risks occur in the production of antiviral vaccines, in research laboratories and in waste-water treatment plants. Risk of pathogenic effects has also been speculated from exposure to engineered microorganisms in laboratory and environmental or agricultural applications. Safety precautions consisting of protective measures, and effective barriers of containment (both physical and biological) have to be advised according to the hazardous characteristics of the organisms.(ABSTRACT TRUNCATED AT 250 WORDS)

The contribution of bank regulation and fair value accounting to procyclical leverage

OpenAIRE

2007-12-01

Full Text Available Abstract Background The benefits of genomics and biotechnology are concentrated primarily in the industrialized world, while their potential to combat neglected diseases in the developing world has been largely untapped. Without building developing world biotechnology capacity to address local health needs, this disparity will only intensify. To assess the potential of genomics to address health needs in the developing world, the McLaughlin-Rotman Centre for Global Health, along with local partners, organized five courses on Genomics and Public Health Policy in the developing world. The overall objective of the courses was to collectively explore how to best harness genomics to improve health in each region. This article presents and analyzes the recommendations from all five courses. Discussion In this paper we analyze recommendations from 232 developing world experts from 58 countries who sought to answer how best to harness biotechnology to improve health in their regions. We divide their recommendations into four categories: science; finance; ethics, society and culture; and politics. Summary The Courses' recommendations can be summarized across the four categories listed above: Science - Collaborate through national, regional, and international networks - Survey and build capacity based on proven models through education, training, and needs assessments Finance - Develop regulatory and intellectual property frameworks for commercialization of biotechnology - Enhance funding and affordability of biotechnology - Improve the academic-industry interface and the role of small and medium enterprise Ethics, Society, Culture - Develop public engagement strategies to inform and educate the public about developments in genomics and biotechnology - Develop capacity to address ethical, social and cultural issues - Improve accessibility and equity Politics - Strengthen understanding, leadership and support at the political level for biotechnology

Leung, Tim

2016-01-01

This book provides an analysis, under both discrete-time and continuous-time frameworks, on the price dynamics of leveraged exchange-traded funds (LETFs), with emphasis on the roles of leverage ratio, realized volatility, investment horizon, and tracking errors. This study provides new insights on the risks associated with LETFs. It also leads to the discussion of new risk management concepts, such as admissible leverage ratios and admissible risk horizon, as well as the mathematical and empirical analyses of several trading strategies, including static portfolios, pairs trading, and stop-loss strategies involving ETFs and LETFs. The final part of the book addresses the pricing of options written on LETFs. Since different LETFs are designed to track the same reference index, these funds and their associated options share very similar sources of randomness. The authors provide a no-arbitrage pricing approach that consistently value options on LETFs with different leverage ratios with stochastic volatility and ...

2007-03-01

Although representative payeeship provided within clinical settings is believed to have therapeutic benefits, its potential negative impact on the therapeutic alliance or client-provider relationship is of concern. This study examined the effects of payeeship and perceived financial leverage on positive and negative dimensions of the client-provider relationship. The sample consisted of 205 adults ages 18 to 65 with axis I disorders who were receiving mental health services from a large urban community mental health clinic. Information about money management characteristics and ratings of the client-provider relationship were collected via face-to-face interview. Fifty-three percent of the sample had a payee or money manager, and 79% of this group had a clinician payee. Respondents with co-occurring psychotic and substance use disorders, lower functioning, and lower insight about their illness were more likely to have a clinician payee. Forty percent of those with a clinician payee reported perceived financial leverage. Having a clinician payee was also associated with perceived financial leverage and with higher levels of conflict in the case management relationship. When examined in combination, financial leverage was found to mediate the effects of payeeship on conflict in the case management relationship (mean+/-SE=2.37+/-1.33, 95% confidence interval=16-5.52, pconflict in the therapeutic alliance when used as a source of treatment leverage. Although payeeship provides important support and may enhance functional outcomes for the patient, decisions about using the mechanism for promoting treatment adherence should take into account the potential disruption to the client-provider relationship.

Environmental biotechnology has emerged as an important measure to tackle the environmental pollution as China experiences great economic success. Over the past decade, much emphasis has been paid to the following fields in environmental biotechnology: microbial degradation of toxic and organic chemicals, bio-treatment of wastewater, waste recycling. The Chinese researchers have done a lot of work to understand the natural degradation processes for organic and toxic compounds and finally to clean these compounds from polluted environments. For the treatment of wastewater, many new processes were proposed and optimized to meet the more strict effluent standards in China. Finally, more and more attention has been paid to the reuse of discharged wastes. In this chapter we review the development in the above fields.

DOWNWARD SLOPING DEMAND CURVES FOR STOCK AND LEVERAGE

Directory of Open Access Journals (Sweden)

Liem Pei Fun

2006-01-01

Full Text Available This research attempts to investigate the effect of downward sloping demand curves for stock on firms' financing decisions. For the same size of equity issuance, firms with steeper slope of demand curves for their stocks experience a larger price drop in their share price compare to their counterparts. As a consequence, firms with a steeper slope of demand curves are less likely to issue equity and hence they have higher leverage ratios. This research finds that the steeper the slope of demand curve for firm's stock, the higher the actual leverage of the firm. Furthermore, firms with a steeper slope of demand curves have higher target leverage ratios, signifying that these firms prefer debt to equity financing in order to avoid the adverse price impact of equity issuance on their share price.

Kuzubaş, Tolga Umut; Saltoğlu, Burak; Sever, Can

2016-11-01

This study probes systemic risk implications of leverage heterogeneity in banking networks. We show that the presence of heterogeneous leverages drastically changes the systemic effects of defaults and the nature of the contagion in interbank markets. Using financial leverage data from the US banking system, through simulations, we analyze the systemic significance of different types of borrowers, the evolution of the network, the consequences of interbank market size and the impact of market segmentation. Our study is related to the recent Basel III regulations on systemic risk and the treatment of the Global Systemically Important Banks (GSIBs). We also assess the extent to which the recent capital surcharges on GSIBs may curb financial fragility. We show the effectiveness of surcharge policy for the most-levered banks vis-a-vis uniform capital injection.

Opportunities in biotechnology.

Science.gov (United States)

Gartland, Kevan M A; Gartland, Jill S

2018-06-08

Strategies for biotechnology must take account of opportunities for research, innovation and business growth. At a regional level, public-private collaborations provide potential for such growth and the creation of centres of excellence. By considering recent progress in areas such as genomics, healthcare diagnostics, synthetic biology, gene editing and bio-digital technologies, opportunities for smart, strategic and specialised investment are discussed. These opportunities often involve convergent or disruptive technologies, combining for example elements of pharma-science, molecular biology, bioinformatics and novel device development to enhance biotechnology and the life sciences. Analytical applications use novel devices in mobile health, predictive diagnostics and stratified medicine. Synthetic biology provides opportunities for new product development and increased efficiency for existing processes. Successful centres of excellence should promote public-private business partnerships, clustering and global collaborations based on excellence, smart strategies and innovation if they are to remain sustainable in the longer term.

Ethical limitations in patenting biotechnological inventions.

Science.gov (United States)

Lugagnani, V

1999-01-01

In order to connect ethical considerations with practical limits to patentability, the moral judgement should possibly move from the exploitation of the invention to the nature and/or objectives of Research and Development (R&D) projects which have produced it: in other words, it appears quite reasonable and logical that Society is not rewarding unethical R&D activities by granting intellectual property rights. As far as biotechnology R&D is concerned, ethical guidance can be derived from the 1996 Council of EuropeOs OConvention for the protection of human rights and dignity of the human being with regard to the application of biology and medicineO, whose Chapter V - Scientific research - provides guidelines on: i. protection of persons undergoing research (e.g. informed consent); ii. protection of persons not able to consent to research; iii. research on embryos in vitro. As far as the specific point of patenting biotechnology inventions is concerned, the four exclusions prescribed by Directive 98/44/EC (i.e. human cloning, human germ-line gene therapy, use of human embryos for commercial purposes, unjustified animal suffering for medical purposes) are all we have in Europe in terms of ethical guidance to patentability. In Italy, in particular, we certainly need far more comprehensive legislation, expressing SocietyOs demand to provide ethical control of modern biotechnology. However it is quite difficult to claim that ethical concerns are being raised by currently awarded biotechnology patents related to living organisms and material thereof; they largely deal with the results of genomic R&D, purposely and usefully oriented toward improving health-care and agri-food processes, products and services. ONo patents on lifeOO can be an appealing slogan of militants against modern biotechnology, but it is far too much of an over-simplified abstraction to become the Eleventh Commandment our Society.

During the last half century, biotechnology has contributed to the development of many important new and useful products that have improved our quality of life. To a large extent, these contributions are attributable to advances in cellular and molecular biology that can be traced to the discovery of DNA. What began as a science involved with manipulations of whole organisms has transcended into an ability to influence organisms at the cellular and molecular levels with greater speed, flexibility and precision than ever before. This has produced significantly improved pharmaceutical, textile, diagnostic, and environmental products, to name just a few. Early in this new century, biotechnology research is expected to literally explode with exciting new and promising opportunities. More importantly, biotechnology research in the low gravity environment of space is expected to play a significant part in this biotechnology revolution by expediting the discovery of important new medical, agricultural and environmental products. .

A Model Suggestion to Predict Leverage Ratio for Construction Projects

Directory of Open Access Journals (Sweden)

Özlem Tüz

2013-12-01

Full Text Available Due to the nature, construction is an industry with high uncertainty and risk. Construction industry carries high leverage ratios. Firms with low equities work in big projects through progress payment system, but in this case, even a small negative in the planned cash flows constitute a major risk for the company.The use of leverage, with a small investment to achieve profit targets large-scale, high-profit, but also brings a high risk with it. Investors may lose all or the portion of the money. In this study, monitoring and measuring of the leverage ratio because of the displacement in cash inflows of construction projects which uses high leverage and low cash to do business in the sector is targeted. Cash need because of drifting the cash inflows may be seen due to the model. Work should be done in the early stages of the project with little capital but in the later stages, rapidly growing capital need arises.The values obtained from the model may be used to supply the capital held in the right time by anticipating the risks because of the delay in cashflow of construction projects which uses high leverage ratio.

Applications of radiations, radioisotopes and other nuclear techniques has contributed a great deal in our understanding of microbial plant and animal biochemistry and molecular biology. Electron microscopy has provided visual evidence for molecular events. Developments in cell tissue culture of both plants and animals and immunology have contributed to advances in what we now refer as biotechnology. This paper focuses on the applications in the high-tech end of biotechnology, limited to the use of recombinant-DNA techniques. Molecular identification of the genes, their cloning and horizontal transfer across the species of microbes, plants and animals and expression of the transferred genes is the major strength of modern biotechnology. The techniques described in this paper have played a significant role in the development of biotechnology. 6 refs

 Basic assumptions and definitions in the analysis of financial leverage

Directory of Open Access Journals (Sweden)

Tomasz Berent

2015-12-01

Full Text Available The financial leverage literature has been in a state of terminological chaos for decades as evidenced, for example, by the Nobel Prize Lecture mistake on the one hand, and the global financial crisis on the other. A meaningful analysis of the leverage phenomenon calls for the formulation of a coherent set of assumptions and basic definitions. The objective of the paper is to answer this call. The paper defines leverage as a value neutral concept useful in explaining the magnification effect exerted by financial activity upon the whole spectrum of financial results. By adopting constructivism as a methodological approach, we are able to introduce various types of leverage such as capital and income, base and non-base, accounting and market value, for levels and for distances (absolute and relative, costs and simple etc. The new definitions formulated here are subsequently adopted in the analysis of the content of leverage statements used by the leading finance textbook.

The biology of planktotrophic larvae of Concholepas concholepas is the main bottleneck towards developing biotechnologies to rear this muricid. Data concerning planktonic larvae development, diets and environmental signals triggering larval settlement and recruitment is scarce. We have begun the study of the molecular and cell biology of embryos, larvae and recruits having as a final goal, the development of appropriate biotechnologies to rear this gastropod. First, an inverse ratio between BuChE and AChE enzyme activities was established. This ratio may be a precise developmental marker for this species. Second, for the first time a phosphoinositide related regulatory pathway is reported in a muricid, opening a new approach to the biotechnological management of larvae. Third, the relation between sulfate in sea water and larval motility was studied. Concentrations below 125 microM sulfate decreases larval motility. The sulfate is incorporated in proteoglycans which participate in different developmental phenomena. Lastly, a genomic Concholepas concholepas DNA sequence, similar to that of a human growth hormone probe was detected. This is very interesting since growth factors are key molecules during development, growth and are involved in food conversion rates in fish and also, in a variety of marine invertebrates.

Dendrimers, commonly referred to as polymeric trees, offer endless opportunities for biotechnological and biomedical applications. By controlling the type, length, and molecular weight of the core, branches and end groups, respectively, the chemical functionality and topology of dendrimeric archetypes can be customized which further can be applied to achieve required solubility, biodegradability, diagnosis and other applications. Given the physicochemical variability of the dendrimers and their hybrids, this review attempts to discuss a full spectrum of recent advances and strides made by these "perfectly designed structures". An extensive biotech/biomimicry application profiling of dendrimers is provided with focus on complex archetypical designs such as protein biomimicry (angiogenic inhibitors, regenerative hydroxyapatite and collagen) and biotechnology applications. In terms of biotechnological advances, dendrimers have provided distinctive advantages in the fields of biocatalysis, microbicides, artificial lights, mitochondrial function modulation, vaccines, tissue regeneration and repair, antigen carriers and even biosensors. In addition, this review provides overview of the extensive chemo-functionalization opportunities available with dendrimers which makes them a perfect candidate for forming drug conjugates, protein hybrids, bio mimics, lipidic derivatives, metal deposits and nanoconjugates thereby making them the most multifunctional platforms for diverse biotechnological applications.

The success of biotechnological research, development and marketing depends to a large extent on the international transfer of information and on the ability to organise biotechnology information into knowledge. To increase the efficiency of information-based approaches, an information strategy has been developed and consists of the following stages: definition of the problem, its structure and sub-problems; acquisition of data by targeted processing of computer-supported bibliographic, numeric, textual and graphic databases; analysis of data and building of specialized in-house information systems; information processing for structuring data into systems, recognition of trends and patterns of knowledge, particularly by information synthesis using the concept of information density; design of research hypotheses; testing hypotheses in the laboratory and/or pilot plant; repeated evaluation and optimization of hypotheses by information methods and testing them by further laboratory work. The information approaches are illustrated by examples from the university-industry joint projects in biotechnology, biochemistry and agriculture.

INTERDEPENDENT ANALYSIS OF LEVERAGE, DIVIDEND, AND MANAGERIAL OWNERSHIP POLICIES: Agencies Perspectives

Directory of Open Access Journals (Sweden)

Wibisono Hardjopranoto

2006-06-01

Full Text Available This paper attempts to investigate interdependent mechanism among leverage, dividend, and managerial ownership policies. This paper considers firm size and economic conditions to control their effect on the relationship among the three policies. The interrelationship between leverage, dividend, and managerial ownership policies will be tested using two-stage least squares. Five exogenous variables are employed in simultaneous equation: current assets and structure of assets as leverage determinants, book to market and return on investment as dividend determinants, and relative return to risk as managerial ownership determinant. The research employs year 1994-2004 data, with 1717 firm years. The research findings can be summarised as follows. First, there is a negative relationship between managerial ownership and leverage policies as suggested by agency theory. Second, there is a relationship between managerial ownership and dividend policies, but the relationship between leverage and dividend is insignificant. Third, the relationship between leverage and dividend is insensitive to economic condition and firm size. Fourth, all exogenous variables have significant effect on endogenous variables, except relative return. Fifth, the effects of exogenous variables are not sensitive to control variables. Sixth, we find that managers show self-interest behaviours by reducing managerial ownership when the economic condition worsens.

Modeling Financial Time Series Based on a Market Microstructure Model with Leverage Effect

Directory of Open Access Journals (Sweden)

Yanhui Xi

2016-01-01

Full Text Available The basic market microstructure model specifies that the price/return innovation and the volatility innovation are independent Gaussian white noise processes. However, the financial leverage effect has been found to be statistically significant in many financial time series. In this paper, a novel market microstructure model with leverage effects is proposed. The model specification assumed a negative correlation in the errors between the price/return innovation and the volatility innovation. With the new representations, a theoretical explanation of leverage effect is provided. Simulated data and daily stock market indices (Shanghai composite index, Shenzhen component index, and Standard and Poor’s 500 Composite index via Bayesian Markov Chain Monte Carlo (MCMC method are used to estimate the leverage market microstructure model. The results verify the effectiveness of the model and its estimation approach proposed in the paper and also indicate that the stock markets have strong leverage effects. Compared with the classical leverage stochastic volatility (SV model in terms of DIC (Deviance Information Criterion, the leverage market microstructure model fits the data better.

The analysis of patent activity is one methodology used for technological monitoring. In this paper, the activity of biotechnology-related patents in Brazil were analyzed through 30 International Patent Classification (IPC) codes published by the Organization for Economic Cooperation and Development (OECD). We developed a program to analyse the dynamics of the major patent applicants, countries and IPC codes extracted from the Brazilian Patent Office (INPI) database. We also identified Brazilian patent applicants who tried to expand protection abroad via the Patent Cooperation Treaty (PCT). We had access to all patents published online at the INPI from 1975 to July 2010, including 9,791 biotechnology patent applications in Brazil, and 163 PCTs published online at World Intellectual Property Organization (WIPO) from 1997 to December 2010. To our knowledge, there are no other online reports of biotechnology patents previous to the years analyzed here. Most of the biotechnology patents filed in the INPI (10.9%) concerned measuring or testing processes involving nucleic acids. The second and third places belonged to patents involving agro-technologies (recombinant DNA technology for plant cells and new flowering plants, i.e. angiosperms, or processes for obtaining them, and reproduction of flowering plants by tissue culture techniques). The majority of patents (87.2%) were filed by nonresidents, with USA being responsible for 51.7% of all biotechnology patents deposited in Brazil. Analyzing the resident applicants per region, we found a hub in the southeast region of Brazil. Among the resident applicants for biotechnology patents filed in the INPI, 43.5% were from São Paulo, 18.3% were from Rio de Janeiro, and 9.7% were from Minas Gerais. Pfizer, Novartis, and Sanofi were the largest applicants in Brazil, with 339, 288, and 245 biotechnology patents filed, respectively. For residents, the largest applicant was the governmental institution FIOCRUZ (Oswaldo Cruz

Thailand faces a significant burden in terms of treating and managing degenerative and chronic diseases. Moreover, incidences of rare diseases are rising. Many of these-such as diabetes, cancer, and inherited inborn metabolic diseases-have no definite treatments or cure. Meanwhile, advanced health biotechnology has been found, in principle, to be an effective solution for these health problems. Qualitative approaches were employed to analyse the current situation and examine existing public policies related to advanced health biotechnologies in Thailand. The results of this analysis were then used to formulate policy recommendations. Our research revealed that the system in Thailand in relation to advanced health biotechnologies is fragmented, with multiple unaddressed gaps, underfunding of research and development (R&D), and a lack of incentives for the private sector. In addition, there are no clear definitions of advanced health biotechnologies, and coverage pathways are absent. Meanwhile, false advertising and misinformation are prevalent, with no responsible bodies to actively and effectively provide appropriate information and education (I&E). The establishment of a specialised institution to fill the gaps in this area is warranted. The development and implementation of a comprehensive national strategic plan related to advanced health biotechnologies, greater investment in R&D and I&E for all stakeholders, collaboration among agencies, harmonisation of reimbursement across public health schemes, and provision of targeted I&E are specifically recommended.

The second part of the biotechnology awareness study focused on health sciences libraries and how well they are meeting the needs of biotechnologists working in the study's nine medical centers. A survey was conducted over a three-month period to assess the demand for biotechnology-related reference services at nine libraries and the sources the librarians used to answer the questions. Data on monographic and current serial holdings were also collected. At the end of the survey period, librarians were asked for their perceptions about biotechnology research at their institutions and in their geographic areas. Their responses were compared to the responses the scientists at the nine schools gave to the same or similar questions. Results showed few biotechnology-related reference questions were asked of the librarians. The recorded questions dealt with a range of biotechnology subjects. MEDLINE was used to answer 77% of the questions received during the survey period. More detailed notes in MeSH and a guide to online searching for biotechnology topics were suggested by the librarians as ways to improve reference service to this group of researchers. Journal collections were generally strong, with libraries owning from 50% to 87% of the titles on a core list of biotechnology journals compiled for this study. All libraries subscribed to the five titles most often cited by the scientists surveyed. Generally, librarians were unaware of the biotechnology-related research being done on their campuses or in their geographic areas. PMID:1998819

Religious voices in biotechnology: the case of gene patenting.

Hanson, M J

1999-01-01

On 18 May 1995, nearly 200 religious leaders joined with leading biotechnology critic Jeremy Rifkin in a press conference named the "Joint Appeal against Human and Animal Patenting," a move that many within the biotechnology industry could only interpret as seeking to inhibit biotechnological advance. What moral and religious concerns motivated this challenge to patenting? How could the biotechnology industry understand and respectfully attend to these concerns? What values were at play in the debates that followed the joint appeal? What lessons for future dialogue can be learned from attempts at conversation between the opposing positions? This essay is a report from a Hastings Center research project that accepted the task of addressing these questions. Specifically, the project focused on the patenting of human genetic material, a subset of the issues raised by the joint appeal.

Biotechnological Applications of Microbial (Per)chlorate Reduction.

Science.gov (United States)

Wang, Ouwei; Coates, John D

2017-11-24

While the microbial degradation of a chloroxyanion-based herbicide was first observed nearly ninety years ago, only recently have researchers elucidated the underlying mechanisms of perchlorate and chlorate [collectively, (per)chlorate] respiration. Although the obvious application of these metabolisms lies in the bioremediation and attenuation of (per)chlorate in contaminated environments, a diversity of alternative and innovative biotechnological applications has been proposed based on the unique metabolic abilities of dissimilatory (per)chlorate-reducing bacteria (DPRB). This is fueled in part by the unique ability of these organisms to generate molecular oxygen as a transient intermediate of the central pathway of (per)chlorate respiration. This ability, along with other novel aspects of the metabolism, have resulted in a wide and disparate range of potential biotechnological applications being proposed, including enzymatic perchlorate detection; gas gangrene therapy; enhanced xenobiotic bioremediation; oil reservoir bio-souring control; chemostat hygiene control; aeration enhancement in industrial bioreactors; and, biogenic oxygen production for planetary exploration. While previous reviews focus on the fundamental science of microbial (per)chlorate reduction (for example see Youngblut et al., 2016), here, we provide an overview of the emerging biotechnological applications of (per)chlorate respiration and the underlying organisms and enzymes to environmental and biotechnological industries.

On the Performance of the Measure for Diagnosing Multiple High Leverage Collinearity-Reducing Observations

Arezoo Bagheri

2012-01-01

Full Text Available There is strong evidence indicating that the existing measures which are designed to detect a single high leverage collinearity-reducing observation are not effective in the presence of multiple high leverage collinearity-reducing observations. In this paper, we propose a cutoff point for a newly developed high leverage collinearity-influential measure and two existing measures ( and to identify high leverage collinearity-reducing observations, the high leverage points which hide multicollinearity in a data set. It is important to detect these observations as they are responsible for the misleading inferences about the fitting of the regression model. The merit of our proposed measure and cutoff point in detecting high leverage collinearity-reducing observations is investigated by using engineering data and Monte Carlo simulations.

Gaisser, Sibylle; Nusser, Michael

2010-01-01

Biotechnological methods have become an important tool in pharmaceutical drug research and development. Today approximately 15 % of drug revenues are derived from biopharmaceuticals. The most relevant indications are oncology, metabolic disorders and disorders of the musculoskeletal system. For the future it can be expected that the relevance of biopharmaceuticals will further increase. Currently, the share of substances in preclinical testing that rely on biotechnology is more than 25 % of all substances in preclinical testing. Products for the treatment of cancer, metabolic disorders and infectious diseases are most important. New therapeutic approaches such as RNA interference only play a minor role in current commercial drug research and development with 1.5 % of all biological preclinical substances. Investments in sustainable high technology such as biotechnology are of vital importance for a highly developed country like Germany because of its lack of raw materials. Biotechnology helps the pharmaceutical industry to develop new products, new processes, methods and services and to improve existing ones. Thus, international competitiveness can be strengthened, new jobs can be created and existing jobs preserved.

2016-11-03

The Center for Global Security Research at Lawrence Livermore National Laboratory convened a workshop on August 19, 2016 to consider “Independent Biotechnology: The Innovation-­Regulation Dilemma”. The topic was motivated by the observation that non-­government funded biotechnology research and development activities have grown and diversified tremendously over the past decade. This sector encompasses a broad range of actors and activities: individuals with private laboratories, community “hackerspaces,” biotechnology incubators, and individual startups. Motivations and aspirations are diverse and include such things as personal curiosity, community education, the invention of new products or services, and even the realization of certain economic, political, or social goals. One driving force is the “democratization” of ever more powerful biological technologies, allowing individual citizens and groups access to capabilities that have traditionally only been available to researchers in universities, research institutes, national laboratories, and large commercial concerns. Another is the rise of alternative financing mechanisms such as “crowdsourcing,” which ostensibly provide greater freedom to innovate, and greater public visibility, but entail looser management oversight and transparency.

The establishment of a specialised institution to fill the gaps in this area is warranted. Conclusion The development and implementation of a comprehensive national strategic plan related to advanced health biotechnologies, greater investment in R&D and I&E for all stakeholders, collaboration among agencies, harmonisation of reimbursement across public health schemes, and provision of targeted I&E are specifically recommended.

As global populations continue to increase, agricultural productivity will be challenged to keep pace without overtaxing important environmental resources. A dynamic and integrated approach will be required to solve global food insecurity and position agriculture on a trajectory toward sustainability. Genetically modified (GM) crops enhanced through modern biotechnology represent an important set of tools that can promote sustainable agriculture and improve food security. Several emerging biotechnology approaches were discussed in a recent symposium organized at the 13th IUPAC International Congress of Pesticide Chemistry meeting in San Francisco, CA, USA. This paper summarizes the innovative research and several of the new and emerging technologies within the field of agricultural biotechnology that were presented during the symposium. This discussion highlights how agricultural biotechnology fits within the context of sustainable agriculture and improved food security and can be used in support of further development and adoption of beneficial GM crops.

The sea will be a source of economic development in the next years. Today the research works in marine biotechnologies supply new products and processes. The introduction in the laboratories of a new technology, synthesis biology, is going to increase the possibilities of creation of new products. Exploitation of product stemming from marine biodiversity has to be made with regard to various rights among which industrial property law, maritime law and the Convention on BioDiversity. All participants involved in the promotion of research in marine biotechnology must address the fair and equitable sharing of any commercial exploitation. Carrying out work involving synthetic biology has increased the number of unanswered questions about how operators should manage in order to avoid any threat of being sued for infringements of IP rights or for alleged bio-piracy. This paper, by no means exhaustive in the field, analyzes some of the issues raised on the modification to the landscape in marine biotechnology by the advent of synthetic biology. Such issues indicate how important the collaboration between researchers, industrialists, lawyers is for allowing proper use of marine biotech. Copyright © 2014 Elsevier B.V. All rights reserved.

The leverage effect on wealth distribution in a controllable laboratory stock market.

Zhu, Chenge; Yang, Guang; An, Kenan; Huang, Jiping

2014-01-01

Wealth distribution has always been an important issue in our economic and social life, since it affects the harmony and stabilization of the society. Under the background of widely used financial tools to raise leverage these years, we studied the leverage effect on wealth distribution of a population in a controllable laboratory market in which we have conducted several human experiments, and drawn the conclusion that higher leverage leads to a higher Gini coefficient in the market. A higher Gini coefficient means the wealth distribution among a population becomes more unequal. This is a result of the ascending risk with growing leverage level in the market plus the diversified trading abilities and risk preference of the participants. This work sheds light on the effects of leverage and its related regulations, especially its impact on wealth distribution. It also shows the capability of the method of controllable laboratory markets which could be helpful in several fields of study such as economics, econophysics and sociology.

Biodiesel has received much attention in recent years. Although numerous reports are available on the production of biodiesel from vegetable oils of terraneous oil-plants, such as soybean, sunflower and palm oils, the production of biodiesel from microalgae is a newly emerging field. Microalgal biotechnology appears to possess high potential for biodiesel production because a significant increase in lipid content of microalgae is now possible through heterotrophic cultivation and genetic engineering approaches. This paper provides an overview of the technologies in the production of biodiesel from microalgae, including the various modes of cultivation for the production of oil-rich microalgal biomass, as well as the subsequent downstream processing for biodiesel production. The advances and prospects of using microalgal biotechnology for biodiesel production are discussed. (author)

Reproductive biotechnology has manifold applications and includes a great innovation potential in livestock. Due to the global changes the new findings and techniques can aid to meet the future challenges. The use of biotechnology in animal production can guarantee enough high quality food for the whole population. Genetic resources of animals can be preserved via sperm and embryo banking. Early diagnosis of hereditary defects, generation of offspring with predetermined sex and the avoidance of animal transports for breeding employing shipment of frozen embryos will improve animal welfare. A special application is the use of animal models for human assisted reproductive technologies. Therefore, not only in Germany research related to the methodologies in reproductive biotechnology and their improvement need to be supported.

Random diffusion and leverage effect in financial markets.

Science.gov (United States)

Perelló, Josep; Masoliver, Jaume

2003-03-01

We prove that Brownian market models with random diffusion coefficients provide an exact measure of the leverage effect [J-P. Bouchaud et al., Phys. Rev. Lett. 87, 228701 (2001)]. This empirical fact asserts that past returns are anticorrelated with future diffusion coefficient. Several models with random diffusion have been suggested but without a quantitative study of the leverage effect. Our analysis lets us to fully estimate all parameters involved and allows a deeper study of correlated random diffusion models that may have practical implications for many aspects of financial markets.

The Current Developments of Agricultural Biotechnologies Market

2016-01-01

Full Text Available Population growth in the context of limited land resources makes the global scientific society research new ways to increase the agricultural yields. Over the past 20 years, biotechnology and GM crops have become widely spread and now are cultivated in 28 countries. The total area of crops has tripled, and it suggests the further vertical and horizontal integration in short term. In 2015, the US Department of Agriculture authorized the commercial use of GM farm animals. The development of agricultural biotechnology market is constrained by opponents of GM crops in more than 160 countries, which include Russia and the European Union, where the production of GM crops is banned due to economic, ethical, ideological and biological reasons. Currently, the EU is seeking to reduce the imports of GM crops and products; Russia's GM imports and exports are prohibited, and the deadline of designing a consolidated position on agricultural biotechnology has been moved to 2017. The author seeks to analyze the volume of production and international trade of agricultural products based on biotechnologies and to describe the main trends in the global market, which could be integrated into the food value chain in Russia. In the context of the worsening economic indicators, the article proposes the possibility of extending the use of GM crops in Russia non-food sector.

Fossil resources, i.e. concentrated carbon from biomass, have been irrecoverably exhausted through modern industrial civilization in the last two hundred years. Serious consequences including crises in resources, environment and energy, as well as the pressing need for direct and indirect exploitation of solar energy, pose challenges to the science and technology community of today. Bioenergy, bulk chemicals, and biomaterials could be produced from renewable biomass in a biorefinery via biocatalysis. These sustainable industries will match the global mass cycle, creating a new form of civilization with new industries and agriculture driven by solar energy. Industrial biotechnology is the dynamo of a bioeconomy, leading to a new protocol for production of energy, bulk chemicals, and materials. This new mode of innovation will place the industry at center stage supported by universities and research institutes. Creativity in industrial biotechnology will be promoted and China will successfully follow the road to green modernization. China's rapid economic development and its traditional capacity in fermentation will place it in an advantageous position in the industrial biotechnology revolution. The development and current status of industrial biotechnology in China are summarized herein.

International Nuclear Information System (INIS)

Ashley, N.V.; Roach, D.J.W.

1990-01-01

This paper gives an overview of the feasibility of the application of biotechnology to nuclear waste treatment. Many living and dead organisms accumulate heavy metals and radionuclides. The controlled use of this phenomenon forms the basis for the application of biotechnology to the removal of radionuclides from nuclear waste streams. An overview of biotechnology areas, namely the use of biopolymers and biosorption using biomass applicable to the removal of radionuclides from industrial nuclear effluents is given. The potential of biomagnetic separation technology, genetic engineering and monoclonal antibody technology is also to be examined. The most appropriate technologies to develop for radionuclide removal in the short term appear to be those based on biosorption of radionuclides by biomass and the use of modified and unmodified biopolymers in the medium term.

Rittmann, Bruce E

2006-06-01

Microbial ecology and environmental biotechnology are inherently tied to each other. The concepts and tools of microbial ecology are the basis for managing processes in environmental biotechnology; and these processes provide interesting ecosystems to advance the concepts and tools of microbial ecology. Revolutionary advancements in molecular tools to understand the structure and function of microbial communities are bolstering the power of microbial ecology. A push from advances in modern materials along with a pull from a societal need to become more sustainable is enabling environmental biotechnology to create novel processes. How do these two fields work together? Five principles illuminate the way: (i) aim for big benefits; (ii) develop and apply more powerful tools to understand microbial communities; (iii) follow the electrons; (iv) retain slow-growing biomass; and (v) integrate, integrate, integrate.

Science.gov (United States)

Stagg, Nicola J; Ghantous, Hanan N; Ladics, Gregory S; House, Robert V; Gendel, Steven M; Hastings, Kenneth L

2013-01-01

A workshop entitled "Challenges and Opportunities in Evaluating Protein Allergenicity across Biotechnology Industries" was held at the 51st Annual Meeting of the Society of Toxicology (SOT) in San Francisco, California. The workshop was sponsored by the Biotechnology Specialty Section of SOT and was designed to present the science-based approaches used in biotechnology industries to evaluate and regulate protein allergenicity. A panel of experts from industry and government highlighted the allergenicity testing requirements and research in the agricultural, pharmaceutical/biopharma, and vaccine biotechnology industries and addressed challenges and opportunities for advancing the science of protein allergenicity. The main learning from the workshop was that immunoglobulin E-mediated allergenicity of biotechnology-derived products is difficult to assess without human data. The approaches currently being used to evaluate potential for allergenicity across biotechnology industries are very different and range from bioinformatics, in vitro serology, in vivo animal testing, in vitro and in vivo functional assays, and "biosimilar" assessments (ie, biotherapeutic equivalents to innovator products). The challenge remains with regard to the different or lack of regulatory requirements for allergenicity testing across industries, but the novel approaches being used with bioinformatics and biosimilars may lead to opportunities in the future to collaborate across biotechnology industries.

Knowledge and Attitudes Towards Biotechnology of Elementary Education Preservice Teachers: The first Spanish experience

Science.gov (United States)

Casanoves, Marina; González, Ángel; Salvadó, Zoel; Haro, Juan; Novo, Maite

2015-11-01

Due to the important impact that biotechnology has on current Western societies, well-informed critical citizens are needed. People prepared to make conscious decisions about aspects of biotechnology that relate to their own lives. Teachers play a central role in all education systems. Thus, the biotechnological literacy of preservice teachers is an important consideration as they will become an influential collective as future teachers of the next generation of children. The attitudes toward science (and biotechnology) that teachers have affect their behavior and influence the way they implement their daily practice of science teaching in school. This study analyzes the attitudes and knowledge of Spanish preservice teachers toward biotechnology. We designed a new survey instrument that was completed by 407 university students who were taking official degree programs in preschool and primary education. Our results point out that although they are aware of biotechnology applications, topics concerning the structure of DNA, management of genetic information inside the cell, genetically modified organism technology and the use of microorganisms as biotechnological tools were not correctly answered. According to our attitude analysis, Spanish preservice teachers could be defined as opponents of genetically modified product acquisition, supporters of biotechnology for medical purposes and highly interested in increasing their knowledge about biotechnology and other scientific advances. Our results show a positive correlation between better knowledge and more positive attitudes toward biotechnology. A Spanish preservice teacher with positive attitudes toward biotechnology tends to be a student with a strong biology background who scored good marks in our knowledge test.

UK biotechnology companies lead the way for Europe

Energy Technology Data Exchange (ETDEWEB)

1984-05-01

A number of new well-structured biotechnology companies have been launched in Britain over the last few years, e.g. Imperial Biotechnology, IQ(Bio) and Celltech, while Wellcome and Searle (U.K.) are established firms, keeping up with the new technology. Imperial Biotechnology, with its accent on development rather than research and making products not in anyone else's catalogue, has produced a whole range of enzymes, biopolymers, antibiotics, and human proteins under contract. Its long term objective is to develop its own bioproducts. IQ(Bio) is poised to enter the diagnostic big league with its enzyme-linked immunoassay (Aelia) technology and intends to pursue opportunities where there is a strict regulatory climate prohibiting the growth of radioimmunoassays, e.g. France and Japan. It plans to produce kits that a doctor can use simply and give results in less than 30 minutes. Celltech has a culture products division which supplies large quantities of monoclonal antibodies, it has a diagnostics and health care research section, a speciality chemicals area and an industrial microbiology sector. Wellcome Biotechnology has an interferon programme which includes a broad range of chemical trials in the anticancer and antiviral areas. The company could supply the entire world market for interferon using cell culture and produces a very large range of conventional vaccines. Searle uses biotechnology as just another means of producing new drugs as they have a large drug development machine in place. A considerable amount of process development work has focused on Searle's artificial sweetener, aspartame, and they are looking at all the technical approaches to aspartame production.

The results indicated that the chemical reduction process has higher energy consumption, approximately 1642 Wh, than the energy consumption of the biotechnological reduction process, which is 5 Wh. The potential of global warming (GWP 100 improved by 71% using the biotechnological route for the production of graphene. Abiotic depletion, the photochemical ozone creation potential, and marine aquatic ecotoxicity potential were improved when the biological route was employed, compared with the chemical route. The eutrophication potential, terrestrial ecotoxicity, and ozone depletion layer changed very little since the main variables involved in the production of graphene oxide and waste management are the same. The biotechnological method can be considered a green technique for the production of graphene, especially given the reduction in the negative effects on global warming, abiotic depletion, the photochemical ozone creation potential, and the marine aquatic ecotoxicity potential.

Full Text Available Since 20 years ago, a public-private alliance has transformed Argentina into a remarkable global actor in developing biotechnological products for food and renewable energies. This strategic alliance resulted in the boosting of scientific knowledge, the extension of the production boundary, the expansion of international trade and the creation of the conditions for an integral development. Furthermore, given the characteristics of biotechnology as a new phenomenon, wto has become the field within where a number of disputes take place, disputes which not only controvert trade issues, but also the State’s limits to design and apply public policies on the matter at issue. As a consequence, the present article seeks to, on the one hand, describe how Argentina built its public policy on Biotechnology and, on the other hand, analyze the challenges that Argentina faces within the multilateral trade system

Interface of nuclear and biotechnologies

International Nuclear Information System (INIS)

Castro Diaz-Balart, F.

2005-01-01

Addressing nuclear and biotechnologies in the International Year of Physics should begin by highlighting the important role that this science has played in the development of both branches of science and technologies. The first as a direct consequence of the Theory of Relativity, the further was considerably influenced by Schroedinger's remarks that there must be a code of some kind that allowed molecules in cells to carry information, making a connection between genes and proteins. Both, like any highly technical endeavor, have also in common that the use of technologies demands a vast accumulation of knowledge, i.e. volumes of scientific research, engineering analysis, strict regulatory controls and a huge amount of information combined with a complex assortment of people with the required educational background, expertise and skills to master it. This presentation briefly explores the ways in which nuclear technology has been used in the last decades of the 20th century in the field of biomedicine applications, which includes the use of radiation to obtain accurate images as well as in diagnosis and therapy. The paper looks at the present prospects of some nuclear methods and instrumentation in the so-called Red biotechnology and its genetically engineered therapeutic agents and diagnostic tests as well as some related perspectives in the field of bioinformatics. As an example of biotechnology being successfully applied to health problems in developing countries the presentation gives an outlook of relevant Cuban achievements in this field. (author)

Advance reservation access control using software-defined networking and tokens

Energy Technology Data Exchange (ETDEWEB)

Chung, Joaquin; Jung, Eun-Sung; Kettimuthu, Rajkumar; Rao, Nageswara S. V.; Foster, Ian T.; Clark, Russ; Owen, Henry

Advance reservation systems allow users to reserve dedicated bandwidth connection resources from advanced high-speed networks. A common use case for such systems is data transfers in distributed science environments in which a user wants exclusive access to the reservation. However, current advance network reservation methods cannot ensure exclusive access of a network reservation to the specific flow for which the user made the reservation. We present here a novel network architecture that addresses this limitation and ensures that a reservation is used only by the intended flow. We achieve this by leveraging software-defined networking (SDN) and token-based authorization. We use SDN to orchestrate and automate the reservation of networking resources, end-to-end and across multiple administrative domains, and tokens to create a strong binding between the user or application that requested the reservation and the flows provisioned by SDN. We conducted experiments on the ESNet 100G SDN testbed, and demonstrated that our system effectively protects authorized flows from competing traffic in the network. (C) 2017 Elsevier B.V.

Full Text Available The objective of this study is to investigate the impact of financial leverage on corporate financial performance of Pakistan’s textile sector from 1999-2012 using panel data. The leverage-performance relationship is examined with a special focus on the Global Financial Crisis of 2007-2008. Both accounting-based (Return on Assets - ROA and market-based (Tobin’s Q measures of corporate financial performance are used. Regression analysis is performed with and without inclusion of financial crisis dummy. Total Debt to Total Assets (TDTA, Long Term Debt to Total Assets (LDTA, Short Term Debt to Total Assets (SDTA and Debt to Equity (DE ratios are used as proxies for financial leverage whereas firm’s size and firm’s efficiency are used as control variables. The results indicate that financial leverage has a negative impact on corporate performance when measured with ROA. Whereas in case of Tobin’s Q, SDTA coefficient is positive. It can be concluded that since cost of borrowing is high in Pakistan and debt capital markets are less developed, firms are forced to resort to banks as their source of debt finance and thus have to repay huge amount of principal and interest which has a heavy toll on their financial health. In addition to this, financial crisis was found to have a negative impact on corporate performance and also affect the leverage-performance relationship.

Although widely used in single-enzyme catalysis process, protein engineering is only being increasingly explored in recent years to achieve more complex in vitro and in vivo biocatalytic processes. This review focuses on major contributions of protein engineering to chemical biotechnology in the field of multi-enzymatic cascade catalysis and metabolic engineering. Especially, we discuss and highlight recent strategies for combining pathway design and protein engineering for the production of novel products. Copyright © 2016. Published by Elsevier Ltd.

The value of tax shields with a fixed book-value leverage ratio

OpenAIRE

Fernandez, Pablo

2005-01-01

The value of tax shields depends only on the nature of the stochastic process of the net increases of debt. The value of tax shields in a world with no leverage cost is the tax rate times the current debt plus the present value of the net increases of debt. We develop valuation formulae for a company that maintains a fixed book-value leverage ratio and show that it is more realistic than to assume, as Miles-Ezzell (1980) do, a fixed market-value leverage ratio. We also show that Miles-Ezzell ...

Leveraging liquid dielectrophoresis for microfluidic applications

International Nuclear Information System (INIS)

Chugh, Dipankar; Kaler, Karan V I S

2008-01-01

Miniaturized fluidic systems have been developed in recent years and offer new and novel means of leveraging the domain of microfluidics for the development of micro-total analysis systems (μTAS). Initially, such systems employed closed microchannels in order to facilitate chip-based biochemical assays, requiring very small quantities of sample and/or reagents and furthermore providing rapid and low-cost analysis on a compact footprint. More recently, advancements in the domain of surface microfluidics have suggested that similar low volume sample handling and manipulation capabilities for bioassays can be attained by leveraging the phenomena of liquid dielectrophoresis and droplet dielectrophoresis (DEP), without the need for separate pumps or valves. Some of the key aspects of this surface microfluidic technology and its capabilities are discussed and highlighted in this paper. We, furthermore, examine the integration and utility of liquid DEP and droplet DEP in providing rapid and automated sample handling and manipulation capabilities on a compact chip-based platform

Biotechnological Applications of Marine Enzymes From Algae, Bacteria, Fungi, and Sponges.

Science.gov (United States)

Parte, S; Sirisha, V L; D'Souza, J S

Diversity is the hallmark of all life forms that inhabit the soil, air, water, and land. All these habitats pose their unique inherent challenges so as to breed the "fittest" creatures. Similarly, the biodiversity from the marine ecosystem has evolved unique properties due to challenging environment. These challenges include permafrost regions to hydrothermal vents, oceanic trenches to abyssal plains, fluctuating saline conditions, pH, temperature, light, atmospheric pressure, and the availability of nutrients. Oceans occupy 75% of the earth's surface and harbor most ancient and diverse forms of organisms (algae, bacteria, fungi, sponges, etc.), serving as an excellent source of natural bioactive molecules, novel therapeutic compounds, and enzymes. In this chapter, we introduce enzyme technology, its current state of the art, unique enzyme properties, and the biocatalytic potential of marine algal, bacterial, fungal, and sponge enzymes that have indeed boosted the Marine Biotechnology Industry. Researchers began exploring marine enzymes, and today they are preferred over the chemical catalysts for biotechnological applications and functions, encompassing various sectors, namely, domestic, industrial, commercial, and healthcare. Next, we summarize the plausible pros and cons: the challenges encountered in the process of discovery of the potent compounds and bioactive metabolites such as biocatalysts/enzymes of biomedical, therapeutic, biotechnological, and industrial significance. The field of Marine Enzyme Technology has recently assumed importance, and if it receives further boost, it could successfully substitute other chemical sources of enzymes useful for industrial and commercial purposes and may prove as a beneficial and ecofriendly option. With appropriate directions and encouragement, marine enzyme technology can sustain the rising demand for enzyme production while maintaining the ecological balance, provided any undesired exploitation of the marine

Pleissner, Daniel; Venus, Joachim

2016-03-01

A drawback of biotechnological processes, where microorganisms convert biomass constituents, such as starch, cellulose, hemicelluloses, lipids, and proteins, into wanted products, is the economic feasibility. Particularly the cost of nitrogen sources in biotechnological processes can make up a large fraction of total process expenses. To further develop the bioeconomy, it is of considerable interest to substitute cost-intensive by inexpensive nitrogen sources. The aim of this mini-review was to provide a comprehensive insight of utilization methods of protein-rich residues, such as fish waste, green biomass, hairs, and food waste. The methods described include (i) production of enzymes, (ii) recovery of bioactive compounds, and/or (iii) usage as nitrogen source for microorganisms in biotechnological processes. In this aspect, the utilization of protein-rich residues, which are conventionally considered as waste, allows the development of value-adding processes for the production of bioactive compounds, biomolecules, chemicals, and materials.

2009-04-01

This report documents implementation strategies to leverage public and private resources for the development of an adequate national security workforce as part of the National Security Preparedness Project (NSPP), being performed under a U.S. Department of Energy (DOE)/National Nuclear Security Administration (NNSA) grant. There are numerous efforts across the United States to develop a properly skilled and trained national security workforce. Some of these efforts are the result of the leveraging of public and private dollars. As budget dollars decrease and the demand for a properly skilled and trained national security workforce increases, it will become even more important to leverage every education and training dollar. This report details some of the efforts that have been implemented to leverage public and private resources, as well as implementation strategies to further leverage public and private resources.

Understanding public perceptions of biotechnology through the "Integrative Worldview Framework".

Science.gov (United States)

De Witt, Annick; Osseweijer, Patricia; Pierce, Robin

2015-07-03

Biotechnological innovations prompt a range of societal responses that demand understanding. Research has shown such responses are shaped by individuals' cultural worldviews. We aim to demonstrate how the Integrative Worldview Framework (IWF) can be used for analyzing perceptions of biotechnology, by reviewing (1) research on public perceptions of biotechnology and (2) analyses of the stakeholder-debate on the bio-based economy, using the Integrative Worldview Framework (IWF) as analytical lens. This framework operationalizes the concept of worldview and distinguishes between traditional, modern, and postmodern worldviews, among others. Applied to these literatures, this framework illuminates how these worldviews underlie major societal responses, thereby providing a unifying understanding of the literature on perceptions of biotechnology. We conclude the IWF has relevance for informing research on perceptions of socio-technical changes, generating insight into the paradigmatic gaps in social science, and facilitating reflexive and inclusive policy-making and debates on these timely issues. © The Author(s) 2015.

Review of computational fluid dynamics applications in biotechnology processes.

Science.gov (United States)

Sharma, C; Malhotra, D; Rathore, A S

2011-01-01

Computational fluid dynamics (CFD) is well established as a tool of choice for solving problems that involve one or more of the following phenomena: flow of fluids, heat transfer,mass transfer, and chemical reaction. Unit operations that are commonly utilized in biotechnology processes are often complex and as such would greatly benefit from application of CFD. The thirst for deeper process and product understanding that has arisen out of initiatives such as quality by design provides further impetus toward usefulness of CFD for problems that may otherwise require extensive experimentation. Not surprisingly, there has been increasing interest in applying CFD toward a variety of applications in biotechnology processing in the last decade. In this article, we will review applications in the major unit operations involved with processing of biotechnology products. These include fermentation,centrifugation, chromatography, ultrafiltration, microfiltration, and freeze drying. We feel that the future applications of CFD in biotechnology processing will focus on establishing CFD as a tool of choice for providing process understanding that can be then used to guide more efficient and effective experimentation. This article puts special emphasis on the work done in the last 10 years. © 2011 American Institute of Chemical Engineers

The paper examines whether security issues and repurchases adjust the capital structure toward the target. The time-series patterns of debt ratios imply that only debt reductions are initiated to offset the accumulated deviation from target leverage. The importance of target leverage in earlier debt-equity choice studies is driven by the subsample of equity issues accompanied by debt reductions. Unlike debt issues and reductions, equity issues and repurchases have no significant lasting effec...

Biotechnological processes are promising alternatives to petrochemical routes for overcoming the challenges of resource depletion in the future in a sustainable way. The strategies of white biotechnology allow the utilization of inexpensive and renewable resources for the production of a broad range of bio-based compounds. Renewable resources, such as agricultural residues or residues from food production, are produced in large amounts have been shown to be promising carbon and/or nitrogen sources. This chapter focuses on the biotechnological production of lactic acid, acrylic acid, succinic acid, muconic acid, and lactobionic acid from renewable residues, these products being used as monomers for bio-based material and/or as food supplements. These five acids have high economic values and the potential to overcome the "valley of death" between laboratory/pilot scale and commercial/industrial scale. This chapter also provides an overview of the production strategies, including microbial strain development, used to convert renewable resources into value-added products.

Biotechnological and molecular approaches for vanillin production: a review.

Science.gov (United States)

Kaur, Baljinder; Chakraborty, Debkumar

2013-02-01

Vanillin is one of the most widely used flavoring agents in the world. As the annual world market demand of vanillin could not be met by natural extraction, chemical synthesis, or tissue culture technology, thus biotechnological approaches may be replacement routes to make production of bio-vanillin economically viable. This review's main focus is to highlight significant aspects of biotechnology with emphasis on the production of vanillin from eugenol, isoeugenol, lignin, ferulic acid, sugars, phenolic stilbenes, vanillic acid, aromatic amino acids, and waste residues by applying fungi, bacteria, and plant cells. Production of biovanillin using GRAS lactic acid bacteria and metabolically engineered microorganisms, genetic organization of vanillin biosynthesis operons/gene cassettes and finally the stability of biovanillin generated through various biotechnological procedures are also critically reviewed in the later sections of the review.

Mills, Zachary Grant; Mao, Wenbin; Alexeev, Alexander

2013-07-01

Fluids are involved in practically all physiological activities of living organisms. However, biological and biorelated flows are hard to analyze due to the inherent combination of interdependent effects and processes that occur on a multitude of spatial and temporal scales. Recent advances in mesoscale simulations enable researchers to tackle problems that are central for the understanding of such flows. Furthermore, computational modeling effectively facilitates the development of novel therapeutic approaches. Among other methods, dissipative particle dynamics and the lattice Boltzmann method have become increasingly popular during recent years due to their ability to solve a large variety of problems. In this review, we discuss recent applications of these mesoscale methods to several fluid-related problems in medicine, bioengineering, and biotechnology. Copyright © 2013 Elsevier Ltd.

In course of this the main attention was paid to some processes modeling in neurons as well as in their aggregates of different forms, including glioma cell masses (1D, 2D, 3D brain processes models. Starting from the models that have only theoretical importance for today, we describe at the end a model which application may be important for the practice. The work was done after the analysis of approximately 250 current publications in fields of biotechnology, including the authors’ original works.

Biodiversity, biotechnologies and the philosophy of biology.

Science.gov (United States)

Galleni, Lodovico

2004-01-01

The thesis of this paper is that in front of the development of biotechnology and of the capacity of techniques of altering the living, there is still a very old philosophy of biology. A rapid historical view is given where the rise and diffusion of the reductionistic paradigm is presented and the connections between this paradigm and biotechnologies are traced. Curiously biotechnologies are still based on the philosophy of F. Bacon. Then the necessity of a new paradigm in biology based on the recent discoveries of complexity is underlined. It is reminded that the main discovery of science of the XX century is that we are living in a small planet of limited resources and frail equilibriums. This discovery asks for a different view of the scientific progress, more linked to the conservation of the Biosphere than to its alteration. Stability is the task for the future interactions of human-kind with nature. For this reason the relationships between stability and diversity are summarised. Finally, as the species is the main step of Biodiversity, a brief discussion of the problems posed by the altering of species barriers is presented.

2015-05-01

Microalgae constitute a diverse group of eukaryotic unicellular organisms that are of interest for pure and applied research. Owing to their natural synthesis of value-added natural products microalgae are emerging as a source of sustainable chemical compounds, proteins and metabolites, including but not limited to those that could replace compounds currently made from fossil fuels. For the model microalga, Chlamydomonas reinhardtii, this has prompted a period of rapid development so that this organism is poised for exploitation as an industrial biotechnology platform. The question now is how best to achieve this? Highly advanced industrial biotechnology systems using bacteria and yeasts were established in a classical metabolic engineering manner over several decades. However, the advent of advanced molecular tools and the rise of synthetic biology provide an opportunity to expedite the development of C. reinhardtii as an industrial biotechnology platform, avoiding the process of incremental improvement. In this review we describe the current status of genetic manipulation of C. reinhardtii for metabolic engineering. We then introduce several concepts that underpin synthetic biology, and show how generic parts are identified and used in a standard manner to achieve predictable outputs. Based on this we suggest that the development of C. reinhardtii as an industrial biotechnology platform can be achieved more efficiently through adoption of a synthetic biology approach. © 2015 The Authors The Plant Journal published by Society for Experimental Biology and John Wiley & Sons Ltd.

Sherman, James H; Munyikwa, Tichafa; Chan, Stephen Y; Petrick, Jay S; Witwer, Kenneth W; Choudhuri, Supratim

2015-11-01

During the 40th Annual Meeting of The Toxicology Forum, the current and potential future science, regulations, and politics of agricultural biotechnology were presented and discussed. The meeting session described herein focused on the technology of RNA interference (RNAi) in agriculture. The general process by which RNAi works, currently registered RNAi-based plant traits, example RNAi-based traits in development, potential use of double stranded RNA (dsRNA) as topically applied pesticide active ingredients, research related to the safety of RNAi, biological barriers to ingested dsRNA, recent regulatory RNAi science reviews, and regulatory considerations related to the use of RNAi in agriculture were discussed. Participants generally agreed that the current regulatory framework is robust and appropriate for evaluating the safety of RNAi employed in agricultural biotechnology and were also supportive of the use of RNAi to develop improved crop traits. However, as with any emerging technology, the potential range of future products, potential future regulatory frameworks, and public acceptance of the technology will continue to evolve. As such, continuing dialogue was encouraged to promote education of consumers and science-based regulations. Copyright © 2015 Elsevier Inc. All rights reserved.

Microalgal lipids biochemistry and biotechnological perspectives.

. Therefore, algal production systems need to be improved and harvesting systems need to be more effective in order for their industrial applications to become more competitive and economically viable. Besides, a reduction of the production cost of microalgal lipids can be achieved by combining lipid production with other commercial applications. The combined production of bioactive products and lipids, when possible, can support the commercial viability of both processes. Hydrophobic compounds can be extracted simultaneously with lipids and then purified, while hydrophilic compounds such as proteins and sugars may be extracted from the defatted biomass. The microalgae also have applications in environmental biotechnology since they can be used for bioremediation of wastewater and to monitor environmental toxicants. Algal biomass produced during wastewater treatment may be further valorized in the biofuel manufacture. It is anticipated that the high microalgal lipid potential will force research towards finding effective ways to manipulate biochemical pathways involved in lipid biosynthesis and towards cost effective algal cultivation and harvesting systems, as well.

Pili and flagella biology, structure, and biotechnological applications.

Science.gov (United States)

Van Gerven, Nani; Waksman, Gabriel; Remaut, Han

2011-01-01

Bacteria and Archaea expose on their outer surfaces a variety of thread-like proteinaceous organelles with which they interact with their environments. These structures are repetitive assemblies of covalently or non-covalently linked protein subunits, organized into filamentous polymers known as pili ("hair"), flagella ("whips") or injectisomes ("needles"). They serve different roles in cell motility, adhesion and host invasion, protein and DNA secretion and uptake, conductance, or cellular encapsulation. Here we describe the functional, morphological and genetic diversity of these bacterial filamentous protein structures. The organized, multi-copy build-up and/or the natural function of pili and flagella have lead to their biotechnological application as display and secretion tools, as therapeutic targets or as molecular motors. We review the documented and potential technological exploitation of bacterial surface filaments in light of their structural and functional traits. Copyright © 2011 Elsevier Inc.

Nutrition by design: a review of biotechnology in functional food

Directory of Open Access Journals (Sweden)

Thomas Reynolds

2016-02-01

Full Text Available Medical institutions in industrial and developing countries are increasingly turning to functional foods as intervention in chronic disease. Advances in genetic engineering have provided methods of purposefully designing functional foods and bioactive compound-producing organisms. This literature review examines the recent history of biotechnological applications in functional food, the state of bioagricultural engineering for high-value compound production, and the challenges that developers face in promulgatingfunctional foods from biotechnological sources. Based on the literature reviewed, it is predicted that adding biotechnologically-produced compounds will be more successful in producing novel functional foods. Conclusion: Current functional food application is frequently hampered by a dearth of foods suitable to the purpose. The concurrent advent of biotechnology means that producers and clinicians are not constrained by limited and precarious natural development. Biotechnology has already produced altered dietary staples that can safely induce real health benefits, but the social approval of genetically modified foodstuffs is inconsistent at best. Modifying microalgae to produce micro and macronutrients, for harvest and incorporation into functional food products, provides the ideal specificity and reliability for bioactive compound use. However, its application in biomedical science is impeded by technical difficulty. It remains to be seen if microorganism engineering willbe able to meet the needs of its many stakeholders, including the functional food community. Nonetheless,the prospect of a flourishing functional food market, and the healthier population it will bring about, certainly makes it worth a try.

Biosafety Assessment of Microbial Strains Used in Biotechnology According to Their Taxonomy

Directory of Open Access Journals (Sweden)

Natalia I. Sheina

2017-03-01

Full Text Available A great variety of biotechnological products are now widely used in different ways in agriculture, medicine, food manufacturing and other areas of our life. Industrialized societies now more than ever depend on the use of genetically engineered products, with many of them synthesized using recombinant strains of microorganisms. There is an opinion that microbial strains used in biotechnology are potentially harmful for human health and the environment. Similar to many other countries, we have enacted environmental legislation in an effort to balance the risks and benefits of using biotechnological strains. Although environmental monitoring rules focus mainly on safety assessments of chemicals, the biosafety assessment of microbial strains used in biotechnology is a very important issue as well. This article summarizes 15 years of research on the biotechnological strains of microbes widely used as producers of various biological substances for industrial purposes, and their environmental and biotechnological applications. In our survey, we tried to evaluate possible adverse effects (general toxicity and damage to the immune system, potential sensitizing effects, and damage to normal microbiota caused by these microbes. It was shown that microscopical fungi of genera Aspergillus, Penicillium and Candida, and some gram-negative bacteria can affect the immune system and disrupt the normal balance of microbial flora of the intestinal tract in rats. The actinomycetes are less dangerous in that they cause fewer side effects. The investigation data obtained can be used to develop safety and hygienic standards for industrial microbes that will help decrease or minimize the occupational risk of infection or damage to the immune system when working with biotechnological strains of microbes.

Can plant biotechnology help break the HIV-malaria link?

Science.gov (United States)

Vamvaka, E; Twyman, R M; Christou, P; Capell, T

2014-01-01

The population of sub-Saharan Africa is at risk from multiple, poverty-related endemic diseases. HIV and malaria are the most prevalent, but they disproportionately affect different groups of people, i.e. HIV predominantly affects sexually-active adults whereas malaria has a greater impact on children and pregnant women. Nevertheless, there is a significant geographical and epidemiological overlap which results in bidirectional and synergistic interactions with important consequences for public health. The immunosuppressive effects of HIV increase the risk of infection when individuals are exposed to malaria parasites and also the severity of malaria symptoms. Similarly, acute malaria can induce a temporary increase in the HIV viral load. HIV is associated with a wide range of opportunistic infections that can be misdiagnosed as malaria, resulting in the wasteful misuse of antimalarial drugs and a failure to address the genuine cause of the disease. There is also a cumulative risk of toxicity when antiretroviral and antimalarial drugs are given to the same patients. Synergistic approaches involving the control of malaria as a strategy to fight HIV/AIDS and vice versa are therefore needed in co-endemic areas. Plant biotechnology has emerged as a promising approach to tackle poverty-related diseases because plant-derived drugs and vaccines can be produced inexpensively in developing countries and may be distributed using agricultural infrastructure without the need for a cold chain. Here we explore some of the potential contributions of plant biotechnology and its integration into broader multidisciplinary public health programs to combat the two diseases in developing countries.

Reengineering the retail/ambulatory pharmacy for provision of biotechnology pharmaceutical services.

Science.gov (United States)

Schneider, P J

1998-07-01

Biotechnology products offer both problems and opportunities for pharmacists. On one hand, they are expensive to purchase and keep on inventory. Typical compensation for outpatient prescriptions does not offset the cost of maintaining the inventory, or providing the education and training that patients often need to use biotechnology products properly. On the other hand, there are issues related to proper storage, preparation, and administration for which pharmacists are well prepared to address. Pharmacists are also convenient, trusted, and provide service at relatively low cost. Examples of special services that pharmacists can provide to improve the use of biotechnology products include patient education, injection clinics, provision of medical supplies, and predrawing syringes for patients. Patients are often sent to many providers for these services, resulting in inconvenience and fragmentation of care. If new compensation methods can be established to support more comprehensive pharmacy services, the use of biotechnology products by patients will improve.

An, Hongjie; Jin, Bo

2012-01-01

Bio-nanotechnology is a new interdisciplinary R&D area that integrates engineering and physical science with biology through the development of multifunctional devices and systems, focusing biology inspired processes or their applications, in particular in medical biotechnology. DNA based nanotechnology, in many ways, has been one of the most intensively studied fields in recent years that involves the use and the creation of bio-inspired materials and their technologies for highly selective biosensing, nanoarchitecture engineering and nanoelectronics. Increasing researches have been offered to a fundamental understanding how the interactions between the nanoparticles and DNA molecules could alter DNA molecular structure and its biochemical activities. This minor review describes the mechanisms of the nanoparticle-DNA binding and molecular interactions. We present recent discoveries and research progresses how the nanoparticle-DNA binding could vary DNA molecular structure, DNA detection, and gene therapy. We report a few case studies associated with the application of the nanoparticle-DNA binding devices in medical detection and biotechnology. The potential impacts of the nanoparticles via DNA binding on toxicity of the microorganisms are briefly discussed. The nanoparticle-DNA interactions and their impact on molecular and microbial functionalities have only drown attention in recent a few years. The information presented in this review can provide useful references for further studies on biomedical science and technology. Copyright © 2012 Elsevier Inc. All rights reserved.

Metabolomics for functional genomics, systems biology, and biotechnology.

Science.gov (United States)

Saito, Kazuki; Matsuda, Fumio

2010-01-01

Metabolomics now plays a significant role in fundamental plant biology and applied biotechnology. Plants collectively produce a huge array of chemicals, far more than are produced by most other organisms; hence, metabolomics is of great importance in plant biology. Although substantial improvements have been made in the field of metabolomics, the uniform annotation of metabolite signals in databases and informatics through international standardization efforts remains a challenge, as does the development of new fields such as fluxome analysis and single cell analysis. The principle of transcript and metabolite cooccurrence, particularly transcriptome coexpression network analysis, is a powerful tool for decoding the function of genes in Arabidopsis thaliana. This strategy can now be used for the identification of genes involved in specific pathways in crops and medicinal plants. Metabolomics has gained importance in biotechnology applications, as exemplified by quantitative loci analysis, prediction of food quality, and evaluation of genetically modified crops. Systems biology driven by metabolome data will aid in deciphering the secrets of plant cell systems and their application to biotechnology.

Overview on the biotechnological production of L-DOPA.

Science.gov (United States)

Min, Kyoungseon; Park, Kyungmoon; Park, Don-Hee; Yoo, Young Je

2015-01-01

L-DOPA (3,4-dihydroxyphenyl-L-alanine) has been widely used as a drug for Parkinson's disease caused by deficiency of the neurotransmitter dopamine. Since Monsanto developed the commercial process for L-DOPA synthesis for the first time, most of currently supplied L-DOPA has been produced by the asymmetric method, especially asymmetric hydrogenation. However, the asymmetric synthesis shows critical limitations such as a poor conversion rate and a low enantioselectivity. Accordingly, alternative biotechnological approaches have been researched for overcoming the shortcomings: microbial fermentation using microorganisms with tyrosinase, tyrosine phenol-lyase, or p-hydroxyphenylacetate 3-hydroxylase activity and enzymatic conversion by immobilized tyrosinase. Actually, Ajinomoto Co. Ltd commercialized Erwinia herbicola fermentation to produce L-DOPA from catechol. In addition, the electroenzymatic conversion system was recently introduced as a newly emerging scheme. In this review, we aim to not only overview the biotechnological L-DOPA production methods, but also to briefly compare and analyze their advantages and drawbacks. Furthermore, we suggest the future potential of biotechnological L-DOPA production as an industrial process.

Biotechnology software in the digital age: are you winning?

Science.gov (United States)

Scheitz, Cornelia Johanna Franziska; Peck, Lawrence J; Groban, Eli S

2018-01-16

There is a digital revolution taking place and biotechnology companies are slow to adapt. Many pharmaceutical, biotechnology, and industrial bio-production companies believe that software must be developed and maintained in-house and that data are more secure on internal servers than on the cloud. In fact, most companies in this space continue to employ large IT and software teams and acquire computational infrastructure in the form of in-house servers. This is due to a fear of the cloud not sufficiently protecting in-house resources and the belief that their software is valuable IP. Over the next decade, the ability to quickly adapt to changing market conditions, with agile software teams, will quickly become a compelling competitive advantage. Biotechnology companies that do not adopt the new regime may lose on key business metrics such as return on invested capital, revenue, profitability, and eventually market share.

Theobroma cacao-The Food of the Gods, provides the raw material for the multibillion dollar chocolate industry and is also the main source of income for about 6 million smallholders around the world. Additionally, cocoa beans have a number of other nonfood uses in the pharmaceutical and cosmetic industries. Specifically, the potential health benefits of cocoa have received increasing attention as it is rich in polyphenols, particularly flavonoids. At present, the demand for cocoa and cocoa-based products in Asia is growing particularly rapidly and chocolate manufacturers are increasing investment in this region. However, in many Asian countries, cocoa production is hampered due to many reasons including technological, political and socio-economic issues. This review provides an overview of the present status of global cocoa production and recent advances in biotechnological applications for cacao improvement, with special emphasis on genetics/genomics, in vitro embryogenesis and genetic transformation. In addition, in order to obtain an insight into the latest innovations in the commercial sector, a survey was conducted on granted patents relating to T. cacao biotechnology. © 2017 The Authors.

The development process has resulted in deforestation. A comprehensive study is needed to obtain an objective solution by integrating the ecological dimension and human dimension. This study was conducted within Balai Raja Wildlife Reserve (BRWR), Bengkalis Regency, Riau Province, Indonesia. We used the social-ecological systems (SES) approach based on local characteristics, categorized into ecological status, social status and actors. Each factoris ranked using Multi-Dimensional Scaling (MDS).BRWR sustainability levels are in moderate condition. The ecological dimension is in a less sustainable state, with leverage: (1) forest conversion; (2) local ecological knowledge; (3) high conservation value. The social dimension is in a less sustainable state, with leverage: (1) community empowerment; (2) social conflict; (3) participation in landscape management. Dimensions actors are on a fairly sustainable status, with leverage: (1) institutional interaction; (2) stakeholder’s commitment; (3) law enforcement. We recommend strengthening community empowerment, local ecological knowledge, interaction, and stakeholder commitment

The evolution of biotechnology and its impact on health care.

Science.gov (United States)

Evens, Ronald; Kaitin, Kenneth

2015-02-01

For more than three decades the field of biotechnology has had an extraordinary impact on science, health care, law, the regulatory environment, and business. During this time more than 260 novel biotechnology products were approved for over 230 indications. Global sales of these products exceeded $175 billion in 2013 and have helped sustain a vibrant life sciences sector that includes more than 4,600 biotech companies worldwide. In this article we examine the evolution of biotechnology during the past three decades and the profound impact that it has had on health care through four interrelated and interdependent tracks: innovations in science, government activity, business development, and patient care. The future impact of biotechnology is promising, as long as the public and private sectors continue to foster policies and provide funds that lead to scientific breakthroughs; governments continue to offer incentives for private-sector biotech innovation; industry develops business models for cost-effective research and development; and all stakeholders establish policies to ensure that the therapeutic advances that mitigate or cure medical conditions that currently have inadequate or no available therapies are accessible to the public at a reasonable cost.

Rethinking production of Taxol® (paclitaxel) using endophyte biotechnology.

Science.gov (United States)

Kusari, Souvik; Singh, Satpal; Jayabaskaran, Chelliah

2014-06-01

Taxol® (generic name paclitaxel) represents one of the most clinically valuable natural products known to mankind in the recent past. More than two decades have elapsed since the notable discovery of the first Taxol®-producing endophytic fungus, which was followed by a plethora of reports on other endophytes possessing similar biosynthetic potential. However, industrial-scale Taxol® production using fungal endophytes, although seemingly promising, has not seen the light of the day. In this opinion article, we embark on the current state of knowledge on Taxol® biosynthesis focusing on the chemical ecology of its producers, and ask whether it is actually possible to produce Taxol® using endophyte biotechnology. The key problems that have prevented the exploitation of potent endophytic fungi by industrial bioprocesses for sustained production of Taxol® are discussed. Copyright © 2014 Elsevier Ltd.

Hartley, Sarah; Gillund, Frøydis; van Hove, Lilian; Wickson, Fern

2016-05-01

Agricultural biotechnology continues to generate considerable controversy. We argue that to address this controversy, serious changes to governance are needed. The new wave of genomic tools and products (e.g., CRISPR, gene drives, RNAi, synthetic biology, and genetically modified [GM] insects and fish), provide a particularly useful opportunity to reflect on and revise agricultural biotechnology governance. In response, we present five essential features to advance more socially responsible forms of governance. In presenting these, we hope to stimulate further debate and action towards improved forms of governance, particularly as these new genomic tools and products continue to emerge.

Alienation from the Objectives of the Patent System: How to Remedy the Situation of Biotechnology Patent.

Science.gov (United States)

Jiang, Li

2018-03-12

Some fundamental biotechnologies hold unprecedented potential to eradicate many incurable diseases. However, in absence of regulations, the power of patent makes the future use of some important biotechnology in few institution's hands. The excessive patents restrict researcher access to the fundamental technologies. It generates concerns and complaints of deteriorating the public health and social welfare. Furthermore, intellectual curiosities, funding, respect among colleagues etc., rather than patents, are the real motivations driving a major ground-breaking discoveries in biotechnology. These phenomena reveal that some biotechnology patents are alienated from the purpose of patent system. Therefore, it is necessary to take some approaches to stop over-patenting these fundamental biotechnology inventions. This article proposes a model regulatory framework for controlling biotechnology patent alienating from the purpose of patent system.

Evens, Ronald P

2016-01-01

The biotechnology segment of the overall biopharma industry has existed for only about 40–45 years, as a driver of new product development. This driving force was initiated with the FDA approval of recombinant human insulin in 1982, originating from the Genentech company. The pharma industry in the early years of 1970s and 1980s engaged with biotechnology companies only to a small extent with their in-licensing of a few recombinant molecules, led by Roche, Eli Lilly, and Johnson and Johnson. However, subsequently and dramatically over the last 25 years, biotechnology has become a primary driver of product and technology innovation and has become a cornerstone in new product development by all biopharma companies. This review demonstrates these evolutionary changes regarding approved products, product pipelines, novelty of the products, FDA approval rates, product sales, financial R&D investments in biotechnology, partnerships, mergers and acquisitions, and patent issues. We now have about 300 biotechnology products approved in USA covering 16 medical disciplines and about 250 indications, with the engagement of 25 pharma companies, along with their biotechnology company innovators and partners. The biotechnology pipeline involves over 1000 molecules in clinical trials, including over 300 molecules associated with the top 10 pharma companies. Product approval rates by the FDA for biotechnology products are over double the rate for drugs. Yes, the R&D paradigm has changed with biotechnology now as one of the major focuses for new product development with novel molecules by the whole biopharma industry.

Leveraging Comparative Genomics to Identify and Functionally Characterize Genes Associated with Sperm Phenotypes in Python bivittatus (Burmese Python

Full Text Available Comparative genomics approaches provide a means of leveraging functional genomics information from a highly annotated model organism’s genome (such as the mouse genome in order to make physiological inferences about the role of genes and proteins in a less characterized organism’s genome (such as the Burmese python. We employed a comparative genomics approach to produce the functional annotation of Python bivittatus genes encoding proteins associated with sperm phenotypes. We identify 129 gene-phenotype relationships in the python which are implicated in 10 specific sperm phenotypes. Results obtained through our systematic analysis identified subsets of python genes exhibiting associations with gene ontology annotation terms. Functional annotation data was represented in a semantic scatter plot. Together, these newly annotated Python bivittatus genome resources provide a high resolution framework from which the biology relating to reptile spermatogenesis, fertility, and reproduction can be further investigated. Applications of our research include (1 production of genetic diagnostics for assessing fertility in domestic and wild reptiles; (2 enhanced assisted reproduction technology for endangered and captive reptiles; and (3 novel molecular targets for biotechnology-based approaches aimed at reducing fertility and reproduction of invasive reptiles. Additional enhancements to reptile genomic resources will further enhance their value.

With the world-wide increase of patients with renal failure, the development of functional renal replacement therapies have gained significant interest and novel technologies are rapidly evolving. Currently used renal replacement therapies insufficiently remove accumulating waste products, resulting in the uremic syndrome. A more preferred treatment option is kidney transplantation, but the shortage of donor organs and the increasing number of patients waiting for a transplant warrant the development of novel technologies. The bioartificial kidney (BAK) is such promising biotechnological approach to replace essential renal functions together with the active secretion of waste products. The development of the BAK requires a multidisciplinary approach and evolves at the intersection of regenerative medicine and renal replacement therapy. Here we provide a concise review embracing a compact historical overview of bioartificial kidney development and highlighting the current state-of-the-art, including implementation of living-membranes and the relevance of extracellular matrices. We focus further on the choice of relevant renal epithelial cell lines versus the use of stem cells and co-cultures that need to be implemented in a suitable device. Moreover, the future of the BAK in regenerative nephrology is discussed. Copyright © 2014 Elsevier Inc. All rights reserved.

Advances in understanding plant biology, novel genetic resources, genome modification, and omics technologies generate new solutions for food security and novel biomaterials production under changing environmental conditions. New gene and germplasm candidates that are anticipated to lead to improved crop yields and other plant traits under stress have to pass long development phases based on trial and error using large-scale field evaluation. Therefore, quantitative, objective, and automated screening methods combined with decision-making algorithms are likely to have many advantages, enabling rapid screening of the most promising crop lines at an early stage followed by final mandatory field experiments. The combination of novel molecular tools, screening technologies, and economic evaluation should become the main goal of the plant biotechnological revolution in agriculture.

Plant biotechnology patents: applications in agriculture and medicine.

Science.gov (United States)

Hefferon, Kathleen

2010-06-01

Recent advances in agricultural biotechnology have enabled the field of plant biology to move forward in great leaps and bounds. In particular, recent breakthroughs in molecular biology, plant genomics and crop science have brought about a paradigm shift of thought regarding the manner by which plants can be utilized both in agriculture and in medicine. Besides the more well known improvements in agronomic traits of crops such as disease resistance and drought tolerance, plants can now be associated with topics as diverse as biofuel production, phytoremediation, the improvement of nutritional qualities in edible plants, the identification of compounds for medicinal purposes in plants and the use of plants as therapeutic protein production platforms. This diversification of plant science has been accompanied by the great abundance of new patents issued in these fields and, as many of these inventions approach commercial realization, the subsequent increase in agriculturally-based industries. While this review chapter is written primarily for plant scientists who have great interest in the new directions being taken with respect to applications in agricultural biotechnology, those in other disciplines, such as medical researchers, environmental scientists and engineers, may find significant value in reading this article as well. The review attempts to provide an overview of the most recent patents issued for plant biotechnology with respect to both agriculture and medicine. The chapter concludes with the proposal that the combined driving forces of climate change, as well as the ever increasing needs for clean energy and food security will play a pivotal role in leading the direction for applied plant biotechnology research in the future.

Sugar cane is a major source of food and fuel worldwide. Biotechnology has the potential to improve economically-important traits in sugar cane as well as diversify sugar cane beyond traditional applications such as sucrose production. High levels of transgene expression are key to the success of improving crops through biotechnology. Here we describe new molecular tools that both expand and improve gene expression capabilities in sugar cane. We have identified promoters that can be used to drive high levels of gene expression in the leaf and stem of transgenic sugar cane. One of these promoters, derived from the Cestrum yellow leaf curling virus, drives levels of constitutive transgene expression that are significantly higher than those achieved by the historical benchmark maize polyubiquitin-1 (Zm-Ubi1) promoter. A second promoter, the maize phosphonenolpyruvate carboxylate promoter, was found to be a strong, leaf-preferred promoter that enables levels of expression comparable to Zm-Ubi1 in this organ. Transgene expression was increased approximately 50-fold by gene modification, which included optimising the codon usage of the coding sequence to better suit sugar cane. We also describe a novel dual transcriptional enhancer that increased gene expression from different promoters, boosting expression from Zm-Ubi1 over eightfold. These molecular tools will be extremely valuable for the improvement of sugar cane through biotechnology.

Dynamic Externalities, Universities and Social Capital Formation in the EU Biotechnology Industry

Directory of Open Access Journals (Sweden)

Malgorzata RUNIEWICZ-WARDYN

2017-03-01

Full Text Available The paper investigates the role of dynamic externalities, university-industry linkages and role of social networking in the biotechnology industry in the European Union (EU. Universities act as platforms for local knowledge spillovers and university-industry cluster development in the biotechnology field. The R&D activities at universities contribute to successful business innovations. However, the relationship between the universities and the local innovation capabilities is much more complex and therefore requires more in-depth analysis. The following study derives from the knowledge of the new economic geography, endogenous growth theory, biotechnology, as well as theories of social capital and social networks. The quantitative research elaborates contemporary literature and databases to find channels of interdependence between local university-based knowledge flows, social capital, and biotechnology cluster performance. The results of the study show that the biotechnology industry relies very much on university-business R&D partnerships and research mobility (e.g. pharmaceutical firms that performed basic research in close cooperation with academia produced more patents. In addition, social networking and informal contacts seem to be a more important for the diffusion of knowledge, especially at the beginning of R&D process, as they allow for building credibility between potential partners.

THE IMPORTANCE OF THE RELATIONSHIP BETWEEN COMPANY AND INCUBATOR FOR BIOTECHNOLOGY DEVELOPMENT

Directory of Open Access Journals (Sweden)

Ana Paula Ferreira Alves

2014-01-01

Full Text Available The biotechnology activities development demands an intense academic and scientific basis, a productive sector capable of transforming academic research in scientific products and services, and the creation of an institutional environment to promote the sector’s development. Moreover, many biotechnology companies establish formal partnerships with Universities (by technological incubator to expand innovative capacity coming into the market. The importance of biotechnology for developing countries is perceived by its ability to promote national development based on knowledge and innovation. In Brazil, the government establishes technological incubators to accelerate the company consolidation. In this way, it is important to study the relationship between the actors involved. In this context, this article aims to analyze the relationship between a technological incubator and a biotech company. To do so, the qualitative approach was adopted to reach the objective. Interviews with incubator’s employees of a Brazilian University and biotechnology company’s managers were conducted. The results show that the company-incubator interaction promoted projects approval which were able to support new researches development and to purchase production equipment. Incubated companies have higher chances of survival in the market from the interaction with University, through the technological incubator. The relationship between the incubator and the biotech company is considered a fundamental condition for biotechnology activities development.

None

2009-02-01

This report documents the identification of strategies to leverage public and private resources for the development of an adequate national security workforce as part of the National Security Preparedness Project (NSPP).There are numerous efforts across the United States to develop a properly skilled and trained national security workforce. Some of these efforts are the result of the leveraging of public and private dollars. As budget dollars decrease and the demand for a properly skilled and trained national security workforce increases, it will become even more important to leverage every education and training dollar. The leveraging of dollars serves many purposes. These include increasing the amount of training that can be delivered and therefore increasing the number of people reached, increasing the number and quality of public/private partnerships, and increasing the number of businesses that are involved in the training of their future workforce.

Financial Leverage Behaviour and Firm Performance: Evidence from Publicly Quoted Companies in Nigeria

Directory of Open Access Journals (Sweden)

Godsday Okoro Edesiri

2014-08-01

Full Text Available This paper scrutinizes financial leverage behaviour and firm performance of publicly quoted companies in Nigeria. Data of Leverage, Profitability and Firm Size were sourced from the Nigerian Stock Exchange Fact-book and Annual Report and Accounts of 120 publicly quoted companies in Nigeria during the period 1990 through 2013. Findings suggest that profitability and firm size had a negative effect on financial leverage behaviour of publicly quoted companies in Nigeria. Thus, it was recommended that firms should carry out projects that would help enhance size and profitability in all aspect of the firm. Size in terms of assets would help increase the internal funding. This in turn will have a positive impact on the financial structure of firm as more of internally generated funds will be used instead of external borrowings. Firms should not assume that making of profit shows good application of leverage as this was not found to be true from the analysis. This implies that the result can be relied upon for policy direction.

The demand for heavy metals is ever increasing with the advance of the industrialized world, whereas worldwide reserves of high-grade ores are diminishing. However, there exist large stockpiles of low and lean grade ores that are yet to be exploited. In addition, heavy metals that are present in a spectrum of waste streams including mine drainage, industrial effluents, river sediments, electronic scraps and ashes are also available for recovery and utilization. Heavy metal recovery from low and lean grade ores using conventional techniques such as pyrometallurgy, etc. chemical metallurgy encompass several inherent constraints like, high energy and capital inputs, and high risk of secondary environmental pollution. As environmental regulations become ever more stringent, particularly regarding the disposal of toxic wastes, the costs for ensuring environmental protection will continue to rise. Therefore, there is a need to utilize more efficient technologies to recover heavy metals from secondary sources in order to minimize capital outlay, environmental impact and to respond to increased demand. Biohydrometallurgy, which exploits microbiological processes to recover heavy metal ions, is regarded as one of the most promising and revolutionary biotechnologies. The products of such processes are deposited in aqueous solution thereby rendering them to be more amenable to containment, treatment and recovery. On top of this, biohydrometallurgy can be conducted under mild conditions, usually without the use of any toxic chemicals. Consequently, the application of biohydrometallurgy in recovery of heavy metals from lean grade ores, and wastes, has made it an eco-friendly biotechnology for enhanced heavy metal production.

2018-01-01

This paper analyzes the patterns of health biotechnology publications in six Latin American countries from 2001 to 2015. The countries studied were Argentina, Brazil, Chile, Colombia, Cuba and Mexico. Before our study, there were no data available on HBT development in half of the Latin-American countries we studied, i.e., Argentina, Colombia and Chile. To include these countries in a scientometric analysis of HBT provides fuller coverage of HBT development in Latin America. The scientometric study used the Web of Science database to identify health biotechnology publications. The total amount of health biotechnology production in the world during the period studied was about 400,000 papers. A total of 1.2% of these papers, were authored by the six Latin American countries in this study. The results show a significant growth in health biotechnology publications in Latin America despite some of the countries having social and political instability, fluctuations in their gross domestic expenditure in research and development or a trade embargo that limits opportunities for scientific development. The growth in the field of some of the Latin American countries studied was larger than the growth of most industrialized nations. Still, the visibility of the Latin American research (measured in the number of citations) did not reach the world average, with the exception of Colombia. The main producers of health biotechnology papers in Latin America were universities, except in Cuba were governmental institutions were the most frequent producers. The countries studied were active in international research collaboration with Colombia being the most active (64% of papers co-authored internationally), whereas Brazil was the least active (35% of papers). Still, the domestic collaboration was even more prevalent, with Chile being the most active in such collaboration (85% of papers co-authored domestically) and Argentina the least active (49% of papers). We conclude that the

Bekemeier, Betty; Riley, Catharine M; Padgett, Stephen M; Berkowitz, Bobbie

2007-01-01

Leveraging funds to sustain the efforts of a grant-funded initiative is often an explicit, or implicit, expectation in philanthropy. However, the magnitude of funds leveraged and the factors that facilitate success in leveraging are rarely researched. An example of one of these grant-funded initiatives is the National Turning Point Initiative. Twenty-one states received funding from The Robert Wood Johnson Foundation as part of this initiative to establish and implement strategic goals for achieving significant statewide public health system improvement through diverse, cross-sector partnerships. Leaders from 17 of these 21 states participated in a two-phased study regarding the leveraging of additional funds for their public health infrastructure improvement activities. This article reports on the second phase of the study. In this phase, key informant interviews were conducted to examine how leveraging of resources occurred as part of this large national initiative. Findings indicate that the combination of a comprehensive planning process and a broad-based partnership was crucial in securing resources to expand their efforts. The ability to strategically respond to unexpected events and opportunities also helped states use their plans and partnerships to "make the case" for additional resources to improve their public health infrastructure.

From Discovery to Production: Biotechnology of Marine Fungi for the Production of New Antibiotics

Science.gov (United States)

Silber, Johanna; Kramer, Annemarie; Labes, Antje; Tasdemir, Deniz

2016-01-01

Filamentous fungi are well known for their capability of producing antibiotic natural products. Recent studies have demonstrated the potential of antimicrobials with vast chemodiversity from marine fungi. Development of such natural products into lead compounds requires sustainable supply. Marine biotechnology can significantly contribute to the production of new antibiotics at various levels of the process chain including discovery, production, downstream processing, and lead development. However, the number of biotechnological processes described for large-scale production from marine fungi is far from the sum of the newly-discovered natural antibiotics. Methods and technologies applied in marine fungal biotechnology largely derive from analogous terrestrial processes and rarely reflect the specific demands of the marine fungi. The current developments in metabolic engineering and marine microbiology are not yet transferred into processes, but offer numerous options for improvement of production processes and establishment of new process chains. This review summarises the current state in biotechnological production of marine fungal antibiotics and points out the enormous potential of biotechnology in all stages of the discovery-to-development pipeline. At the same time, the literature survey reveals that more biotechnology transfer and method developments are needed for a sustainable and innovative production of marine fungal antibiotics.

Martin, Michael W.; Shen, Yuzhong

2011-01-01

Serious games can and should leverage the unique qualities of video games to effectively deliver educational experiences for the learners. However, leveraging these qualities is incumbent upon understanding what these unique 'game' qualities are , and how they can facilitate the learning process. This paper presents an examination of the meaning of the term 'game' . as it applies to both serious games and digital entertainment games. Through the examination of counter examples, we derive three game characteristics; games are self contained, provide a variety of meaningful choices, and are intrinsically compelling. We also discuss the theoretical educational foundations which support the application of these 'game qualities' to educational endeavors. This paper concludes with a presentation of results achieved through the application of these qualities and the applicable educational theories to teach learners about the periodic table of elements via a serious game developed by the authors.

Directory of Open Access Journals (Sweden)

Aldea Mita Cheryta

2018-02-01

Full Text Available This research aimed to analyze the effect of leverage and asymmetry information on the firm value through cash holding as mediation variable. The populations of this research were all the firms which listed on the Indonesia Stock Exchange since 2012 – 2015. A sample of this research was saturated sample and census, consisted 56 firms related the population criteria.  This research used secondary data from the firm financial report through path analysis method. This research showed that leverage had a negative effect on the cash holdings, asymmetry information had a negative effect on the firm value through cash holding, and cash holding had a negative effect on the firm value.  With leverage and effect on cash, holding cannot affect the firm value, due to investor risk-averse, investor risk seeker, and neutral investor has their own point of view in assessing the company. Cash holdings can lead to asymmetric information that can lead to agency conflict that can affect a company's performance, so that indirectly, with the existence of asymmetry information had an effect on the declining the firm value.

Full Text Available Biotechnology is expected to be a great technological revolution followed by information technology. It is an application of scientific and engineering principles to the processing of material by biological agents to provide better goods and services to mankind. Commercially its techniques are applied long back in 6 th century in the art of brewing, wine making and baking. It has progressed there after crossing different land marks. Modern biotechnology has developed significantly in the late 19 th century with groundbreaking discoveries applicable in medicine, food, agriculture, chemistry, environmental protection and many more industries. It is widely used in the development of high-yielding, disease-resistant, better quality varieties by applying tissue culture and recombinant DNA techniques. It has wide application in animal breeding using techniques such as artificial insemination, in vitro fertilization and embryo transfer. Specific enzymes used in laundry, fuel and leather industries for better quality, economically feasible and environmental friendly production. Biotechnology in healthcare system uses body′s own tools and weapons to fight against diseases, manufacturing of targeted therapeutic proteins, gene therapy and so on. Novel approaches such as proteomics and structural biology are contributing to understanding the chemistry of life and diseases. Malfunctioning gene replaced with correctly functioning gene by using gene therapy. Tissue engineering has opened up the use of in vitro developed tissue or organ in repairing wounded tissue and system biology which is a computer-based approach to understand cell functions. Although every new discovery related to biology and its implications is significant and has taken the technology ahead. This includes applications, commercialization, controversies, media exposure and so on. Hence, we have enlisted some of the chronological development avenues in biotechnology across the world.

With its diverse, living marine resources and rapidly growing educational and research infrastructure, the Sultanate of Oman is well-positioned to take advantage of the commercial opportunities presented by marine biotechnology. In recognition of potential development, an international symposium, Marine Biotechnology-Emerging Opportunities and Future Perspectives, was held in Muscat, November 12-13, 2013. Three keynote addresses were given, 23 oral presentations made, and a poster exhibition held. The final session reviewed national and regional issues, and the delegates agreed informally on a number of future actions. The potential for future development of marine biotechnology was recognized by all delegates, and following the symposium, they were surveyed for their views on how best to sustain and develop new activities. One hundred percent of respondents found the meeting useful and would support future symposia in the region. Fifty-one percent of Omani respondents recognized major organizational challenges and obstacles to the development of marine biotechnology compared with 23 % of overseas respondents. The need for greater collaboration between research institutions within the GCC region was recognized by 98 % of all respondents. The presentations and survey outcomes are reviewed in this paper.

An updated view on horseradish peroxidases: recombinant production and biotechnological applications.

Science.gov (United States)

Krainer, Florian W; Glieder, Anton

2015-02-01

Horseradish peroxidase has been the subject of scientific research for centuries. It has been used exhaustively as reporter enzyme in diagnostics and histochemistry and still plays a major role in these applications. Numerous studies have been conducted on the role of horseradish peroxidase in the plant and its catalytic mechanism. However, little progress has been made in its recombinant production. Until now, commercial preparations of horseradish peroxidase are still isolated from plant roots. These preparations are commonly mixtures of various isoenzymes of which only a small fraction has been described so far. The composition of isoenzymes in these mixed isolates is subjected to uncontrollable environmental conditions. Nowadays, horseradish peroxidase regains interest due to its broad applicability in the fields of medicine, life sciences, and biotechnology in cancer therapy, biosensor systems, bioremediation, and biocatalysis. These medically and commercially relevant applications, the recent discovery of new natural isoenzymes with different biochemical properties, as well as the challenges in recombinant production render this enzyme particularly interesting for future biotechnological solutions. Therefore, we reviewed previous studies as well as current developments with biotechnological emphasis on new applications and the major remaining biotechnological challenge-the efficient recombinant production of horseradish peroxidase enzymes.

2007-10-01

Full Text Available Organisational culture discourse mandates a linear approach of diagnosis, measurement and gap analysis as standard practice in relation to most culture change initiatives. Therefore, a problem solving framework geared toward “fixing�? and/or realigning an organisation’s culture is usually prescribed. The traditional problem solving model seeks to identify gaps between current and desired organisational cultural states, inhibiting the discovery of an organisation’s unique values and strengths, namely its cultural capital. In pursuit of discovering and leveraging organisational cultural capital, a descriptive case study is used to show how an Appreciative Inquiry process can rejuvenate the spirit of an organisation as a system-wide inquiry mobilises a workforce toward a shared vision.

2013-01-01

During the Global Financial Crisis, regulators imposed short-selling bans to protect financial institutions. The rationale behind the bans was that “bear raids”, driven by short-sellers, would increase the individual and systemic risk of financial institutions, especially for institutions with high leverage. This study uses Extreme Value Theory to estimate the effect of short-selling on financial institutions’ individual and systemic risks in France, Italy and Spain; it also analyses the rela...

Forecasting stock return volatility: A comparison between the roles of short-term and long-term leverage effects

Science.gov (United States)

Pan, Zhiyuan; Liu, Li

2018-02-01

In this paper, we extend the GARCH-MIDAS model proposed by Engle et al. (2013) to account for the leverage effect in short-term and long-term volatility components. Our in-sample evidence suggests that both short-term and long-term negative returns can cause higher future volatility than positive returns. Out-of-sample results show that the predictive ability of GARCH-MIDAS is significantly improved after taking the leverage effect into account. The leverage effect for short-term volatility component plays more important role than the leverage effect for long-term volatility component in affecting out-of-sample forecasting performance.
