A puzzling medical syndrome caused by substances grown in a genetically engineered bacterium could have profound consequences for the entire biotechnology industry-if Jeremy Rifkin has his way. Rifkin, the controversial biotech critic, has filed a petition based on the eosinophilia-myalgia syndrome (EMS) with the Food and Drug Administration. In it, he asks that the FDA's review of all products made by genetic engineering techniques be suspended until strict new rules are in place to protect the public. The problem is that no one yet knows whether the specific contaminant that has caused up to 5000 EMS cases and 27 deaths was actually the result of genetic engineering. It might well have been the result of problems with chemical purification steps that have little to do with molecular genetics. Until now there has been no way to resolve that uncertainty. But help is on the way-in the form of a recently published animal model of the disease that should eventually enable researchers to pinpoint the precise cause of the syndrome.
Biotechnology companies face ethical challenges of two distinct types: bioethical challenges faced on account of the nature of work in the life sciences, and corporate ethical challenges on account of their nature as commercial entities. The latter set of challenges has received almost no attention at all in the academic literature or media. This paper begins to remedy that lacuna, examining ethical issues that arise specifically on account of the status of biotech companies as commercial entities. The focus here is on three representative issues: product safety, corporate social responsibility, and corporate governance. It is argued that each of these issues poses particular ethical challenges for companies in the biotech sector. In the area of product safety, it is noted that biotech companies face particular challenges in determining what counts as a "safe" product, given the contentious nature of what might count as a "harm" in the biotech field. In the area of corporate social responsibility, the adoption of a "stakeholder approach" and an attempt to manage the social consequences of products pose special challenges for biotech companies. This is due to the enormous range of groups and individuals claiming to have a stake in the doings of such companies, and the trenchant controversies over just what the social consequences of various biotechnologies might be. In the area of corporate governance, biotech companies need to seek out and follow best practices regarding the ways in which information, authority, and influence flow between a company's shareholders, managers, and Board of Directors, if they are to avoid duplicating the ethical and financial scandal that brought down ImClone. An important meta-issue, here--one that renders each of these corporate ethical challenges more vexing--is the difficulty of finding the appropriate benchmarks for ethical corporate behavior in a field as controversial, and as rapidly evolving, as biotechnology.

Based on a qualitative study analyzing a series of interviews with dedicated biotech entrepreneurs and high-level investors, "Biotech Funding Trends" provides a comprehensive overview of current trends in biotech funding by taking a close look behind the scenes of the biotech industry. In particular, it illustrates the tensions between both key players based on their different backgrounds and expectations. Here we outline the various funding opportunities for the biotech industry in Europe and identify ways for both sides, entrepreneurs and investors to overcome their prejudices to successfully thrive in a competitive environment. The results are also discussed in the light of the current financial and economic crisis.

Biotechnology is a life science-based technique especially used in agriculture, medicine and food sciences. It is generally defined as the manipulation in organisms to generate products for the welfare of the world. Biotechnology combines disciplines such as genetics, biochemistry, microbiology, and cell biology along with information technology, chemical engineering, robotics etc. It includes basic industries such as food processing, tissue culture, plant development and other sophisticated ones such as recombinant therapeutics and diagnostics. Biotechnology, globally recognized as a rapidly emerging and far-reaching technology, is aptly described as the "technology of hope" for its promise of food, health and environmental sustainability. In India, biotechnology employs more than 10 000 people and generates roughly US$ 500 million in revenue annually. The biotechnology market has increased its sales from Rs. 50 billion in 1997 to Rs.70 billion in 2000, and is expected to cross Rs. 240 billion by the year 2010. In India, the human health biotech products account for 60% of the total market; agribiotech and veterinary 25%, medical devices, contract research and development (R&D), reagents and supplies constitute the remaining 15% Moreover, to facilitate foreign investment, capital and government policies are being revised. Other important industries include industrial enzyme manufacture, bioinformatics, and medical devices. Biotechnology has had limited appeal so far on our capital markets, and we have less then a dozen biotech companies listed on the public markets.

This review introduces the America Invents Act (AIA), a comprehensive reform of U.S. law on patentability and patent enforceability that Congress enacted in 2011. The AIA's most publicized change transforms the United States from a "first-to-invent" system to a "first-inventor-to-file" regime, bringing U.S. patent law more in line with the patent systems of nearly every other industrialized country in the world. This new system requires small companies and independent inventors to toe the line against larger competitors in what many have called a "race to the patent office." But a closer look at the AIA reveals several opportunities for smaller entities that may even the playing field, particularly for innovators in the biotech sector. This article addresses changes that the AIA brings to U.S. patent law, keeping an eye toward issues relevant to biotech companies.

Patents on biotech products have a scope that goes well beyond what is covered by the most widely applied ethical justifications of intellectual property. Neither natural rights theory from Locke, nor public interest theory of IP rights justifies the wide scope of legal protection. The article takes human genes as an example, focusing on the component that is not invented but persists as unaltered gene information even in the synthetically produced complementary DNA, the cDNA. It is argued that patent on cDNA holds this information captive, or illegitimately appropriates it in limiting other researchers and inventors' opportunity to explore new functions and uses based on this non-invented information. A tighter connection between legal IP protection and the use description stated in the patent claim is suggested. By binding protection to the product's foreseeable functions and use, instead of the product itself and all future uses of it, legitimacy of biotech product patents is restored.

In the early 1990s, some were skeptical that genetically modified (GM) crops, now referred to as biotech crops, could deliver improved products and make an impact at the farm level. There was even more skepticism that developing countries would adopt biotech crops. The adoption of and commercialization of biotech crops in 2008 is reviewed. The impact of biotech crops are summarized including their contribution to: global food, feed and fiber security; a safer environment; a more sustainable agriculture; and the alleviation of poverty, and hunger in the developing countries of the world. Future prospects are discussed. Notably, Egypt planted Bt maize for the first time in 2008 thereby becoming the first country in the Arab world to commercialize biotech crops.

The Chinese biotech industry is going through a period of fast growth, and with its huge population, China is predicted to be the biggest single-country market in the world. However, the Chinese biotech industry has to tackle the critical issue of innovation, which should be the driving force for China's development into an advanced and responsible country. Here, in this article, the authors review the history of the Chinese biotech industry, exemplified by the development of genetically engineered drugs during the last 20 years, and also point out its the future.

A typical biotech process starts with the vial of the cell bank, ends with the final product and has anywhere from 15 to 30 unit operations in series. The total number of process variables (input and output parameters) and other variables (raw materials) can add up to several hundred variables. As the manufacturing process is widely accepted to have significant impact on the quality of the product, the regulatory agencies require an assessment of process comparability across different phases of manufacturing (Phase I vs. Phase II vs. Phase III vs. Commercial) as well as other key activities during product commercialization (process scale-up, technology transfer, and process improvement). However, assessing comparability for a process with such a large number of variables is nontrivial and often companies resort to qualitative comparisons. In this article, we present a quantitative approach for assessing process comparability via use of chemometrics. To our knowledge this is the first time that such an approach has been published for biotech processing. The approach has been applied to an industrial case study involving evaluation of two processes that are being used for commercial manufacturing of a major biosimilar product. It has been demonstrated that the proposed approach is able to successfully identify the unit operations in the two processes that are operating differently. We expect this approach, which can also be applied toward assessing product comparability, to be of great use to both the regulators and the industry which otherwise struggle to assess comparability.

On June 7 , 1998, the Swiss citizens voted on a constitutional amendment, which could have jeopardised the future of biotechnological research in Switzerland. Scientists and opinion leaders around the world expected the referendum with great anxiety. 'Nature', in an editorial, had firmly stated that the Swiss way showed 'how not to run a country', the 'Economist', a week prior to the referendum, had written that the Swiss might be the only people in the world who decided on their own to forego a world class position in scientific research. In fact, the Swiss did none of that. They rejected the constitutional amendment with an overwhelming majority of 67 per cent of the votes, and what started out as a dramatic threat to scientific research in Switzerland became a platform in favour of modern biotechnology. The presentation addresses some of the key features of the Swiss biotech campaign, analyses the success factors of the campaign, provides an insight in the most in-depth collection of data on public perception of biotechnology in the world, and draws conclusions as to what extent the Swiss experience can be of use in the way to communicate on modem science. The result of the Swiss referendum has convincingly shown that successful communication of modem science is possible if - scientists, authorities, and the industry accept the challenge to cope with the demands of communicating with the public at large, - there is a clear understanding that the public's needs may often be based on psychological rather than on logic scientific reasons, - all participants in the dialogue are willing to forego scientific jargon for clear understandable language, i.e. understand that it is hardly the public's fault if messages do not get across, - everybody accepts that dialogue, information, and education on modem science is a long-haul task. The Swiss biotech referendum was seen as a major threat to Switzerland as a leading country of scientific research. However, something which

Every day Science moves little steps forward, contributing to the progress of our society. Sometimes, however, a single invention revolutionizes the world. Indeed, the invention of woodblock printing and development of industrial-scale printing-press in the 15. century have changed our society. 3D-printing is now boosting another revolution. The production of custom-made objects from a virtual model will trigger a rapid development of a more versatile, less expensive manufacturing sector for the on-demand market. The real revolution, however, is represented by 3D-printing in biomedicine. 3D-bioprinting represents the future of the Red-Biotech. This technology, indeed, will be able to build ex-novo organs using biocompatible materials and human cells; replace the allograft transplants, eliminating waiting lists that often make the difference between life and death; and provide more predictive, less expensive experimental models, replacing animal tests. The high innovation content of this technology, can make the difference between being obsolete and new [it

ABSTRACT With the increasing number of genetically modified (GM) events, traits, and crops that are developed to benefit the global population, approval of these technologies for food, feed, cultivation and import in each country may vary depending on needs, demand and trade interest. ISAAA established a GMO Approval Database to document global approvals of biotech crops. GM event name, crops, traits, developer, year of approval for cultivation, food/feed, import, and relevant dossiers were sourced from credible government regulatory websites and biosafety clearinghouses. This paper investigates the trends in GM approvals for food, feed and cultivation based on the number of approving countries, GM crops, events, and traits in the last 23 y (1992–2014), rationale for approval, factors influencing approvals, and their implications in GM crop adoption. Results show that in 2014, there was an accumulative increase in the number of countries granting approvals at 29 (79% developing countries) for commercial cultivation and 31 (70% developing countries) for food and 19 (80% developing developing) for feed; 2012 had the highest number of approving countries and cultivation approvals; 2011 had the highest number of country approvals for feed, and 2014 for food approvals. Herbicide tolerance trait had the highest events approved, followed by insect tolerance traits. Approvals for food product quality increased in the second decade. Maize had the highest number of events approved (single and stacked traits), and stacked traits product gradually increased which is already 30% of the total trait approvals. These results may indicate understanding and acceptance of countries to enhance regulatory capability to be able to benefit from GM crop commercialization. Hence, the paper provided information on the trends on the growth of the GM crop industry in the last 23 y which may be vital in predicting future GM crops and traits. PMID:26039675

Plants derived through agricultural biotechnology, or genetically modified organisms (GMOs), may affect human health and ecological environment. A living GMO is also called a living modified organism (LMO). Biotech cotton is a GMO in food or feed and also an LMO in the environment. Recently, two varieties of biotech cotton, MON 15985 and MON 88913, were developed by Monsanto Co. The detection method is an essential element for the GMO labeling system or LMO management of biotech plants. In this paper, two primer pairs and probes were designed for specific amplification of 116 and 120 bp PCR products from MON 15985 and MON 88913, respectively, with no amplification from any other biotech cotton. Limits of detection of the qualitative method were all 0.05% for MON 15985 and MON 88913. The quantitative method was developed using a TaqMan real-time PCR. A synthetic plasmid, as a reference molecule, was constructed from a taxon-specific DNA sequence of cotton and two construct-specific DNA sequences of MON 15985 and MON 88913. The quantitative method was validated using six samples that contained levels of biotech cotton mixed with conventional cotton ranging from 0.1 to 10.0%. As a result, the biases from the true value and the relative deviations were all within the range of +/-20%. Limits of quantitation of the quantitative method were all 0.1%. Consequently, it is reported that the proposed detection methods were applicable for qualitative and quantitative analyses for biotech cotton MON 15985 and MON 88913.

There are about 80 biotech crop events that have been approved by safety assessment in Korea. They have been controlled by genetically modified organism (GMO) and living modified organism (LMO) labeling systems. The DNA-based detection method has been used as an efficient scientific management tool. Recently, the multiplex polymerase chain reaction (PCR) and DNA chip have been developed as simultaneous detection methods for several biotech crops' events. The event-specific multiplex PCR method was developed to detect five biotech maize events: MIR604, Event 3272, LY 038, MON 88017 and DAS-59122-7. The specificity was confirmed and the sensitivity was 0.5%. The screening DNA chip was developed from four endogenous genes of soybean, maize, cotton and canola respectively along with two regulatory elements and seven genes: P35S, tNOS, pat, bar, epsps1, epsps2, pmi, cry1Ac and cry3B. The specificity was confirmed and the sensitivity was 0.5% for four crops' 12 events: one soybean, six maize, three cotton and two canola events. The multiplex PCR and DNA chip can be available for screening, gene-specific and event-specific analysis of biotech crops as efficient detection methods by saving on workload and time. © 2014 Society of Chemical Industry. © 2014 Society of Chemical Industry.

In the quality by design (QbD) paradigm, global regulatory agencies have introduced the concepts of quality risk management and knowledge management (KM) as enablers for an enhanced pharmaceutical quality system. Although the concept of quality risk management has been well elucidated in the literature, the topic of KM has received relatively scant attention. In this paper we present an opinion on KM in the QbD paradigm as it relates to the manufacturing of biotech therapeutic products. Both academic and industrial viewpoints have been considered and key gaps have been elucidated. The authors conclude that there is an urgent need for the biotech industry to create efficient KM approaches if they wish to be successful in QbD implementation. Copyright © 2015 Elsevier Ltd.

Full Text Available Open data is considered the new oil. As oil can be used to produce fertilisers, pesticides, lubricants, plastics and many other derivatives, so data is considered the commodity to use and re-use to create value. The number of initiatives supporting free access to data has increased in the last years and open data is becoming the norm in the public sector; the approach empowers stakeholders and nurtures the economy. Even if at early stage, private companies also are adapting to the open data market. A survey was conducted to which thirteen companies of different size (from micro enterprises to world-leading pharmas in the pharmaceutical and biotech sector and representing four business models archetypes of companies exploiting open data (aggregators, developers, enrichers and enablers participated. The information collected provides a snapshot of the use of open data by the pharmaceutical and biotech industry in 2015–2016. The companies interviewed use open data to complement proprietary data for research purposes, to implement licensing-in/licensing-out strategies, to map partnerships and connections among players or to identify key expertise and hire staff. Pharmaceutical and biotech companies have made of the protection of knowledge a dogma at the foundation of their business models, but using and contributing to the open data movement may change their approach to intellectual property and innovation.

Analytical methods are very important in the control of genetically modified organism (GMO) labeling systems or living modified organism (LMO) management for biotech crops. Event-specific primers and probes were developed for qualitative and quantitative analysis for biotech maize event 3272 and LY 038 on the basis of the 3' flanking regions, respectively. The qualitative primers confirmed the specificity by a single PCR product and sensitivity to 0.05% as a limit of detection (LOD). Simplex and duplex quantitative methods were also developed using TaqMan real-time PCR. One synthetic plasmid was constructed from two taxon-specific DNA sequences of maize and two event-specific 3' flanking DNA sequences of event 3272 and LY 038 as reference molecules. In-house validation of the quantitative methods was performed using six levels of mixing samples, from 0.1 to 10.0%. As a result, the biases from the true value and the relative deviations were all within the range of +/-30%. Limits of quantitation (LOQs) of the quantitative methods were all 0.1% for simplex real-time PCRs of event 3272 and LY 038 and 0.5% for duplex real-time PCR of LY 038. This study reports that event-specific analytical methods were applicable for qualitative and quantitative analysis for biotech maize event 3272 and LY 038.

Immunoassay methods are available for detection and quantitation of proteins expressed by most biotechnology-derived crops in commercial production. The 2 most common test formats are enzyme-linked immunosorbent assay (ELISA) and immunochromatographic (lateral flow) strip tests. Two ELISA methods, one for Roundup Ready soybeans and one for MON810 CrylAb corn, were the subject of large international collaborative studies and were demonstrated to quantitatively determine the concentrations of biotech crops in samples of ground grain. Quantitative ELISA methods are also useful for analysis of processed fractions of agricultural commodities such as soybean toasted meal or corn flour. Both strip tests and ELISAs for biotech crops are currently being used on a large scale in the United States to manage the sale and distribution of grain. In these applications, tests are used to determine if the concentration of biotech grain is above or below specified threshold limits. Using existing U.S. Department of Agriculture sampling techniques, the reliability of the threshold determination is expressed in terms of statistical confidence rather than analytical precision. Combining the use of protein immunoassays with Identity Preservation systems provides an effective means of characterizing the raw and processed agricultural inputs to the food production system in a way that allows food producers to comply with labeling laws.

Biotechnological intervention in the development of crops has opened new vistas in agriculture. Central to the accomplishment of the Millennium Development Goals (MDGs), biotech-agriculture is essential in meeting these targets. Biotech crops have already made modest contributions toward ensuring food and nutrition security by reducing losses and increasing productivity, with less pesticide input. These crops could help address some of the major challenges in agriculture-based economies created by climate change. Projections of global climate change expect the concentration of greenhouse gases to increase, aridization of the environment to increase, temperature fluctuations to occur sharply and frequently, and spatial and temporal distribution of rainfall to be disturbed-all of which will increase abiotic stress-related challenges to crops. Countering these challenges and to meet the food requirement of the ever-increasing world population (expected to reach 9 billion by 2030) we need to (1) develop and use biotech crops for mitigating adverse climatic changes; (2) develop biotech crops resilient to adverse environmental conditions; and (3) address the issues/non-issues raised by NGO's and educate the masses about the benefits of biotech crops.

A general mathematical framework has been proposed in this work for scheduling of a multiproduct and multipurpose facility involving manufacturing of biotech products. The specific problem involves several batch operations occurring in multiple units involving fixed processing time, unlimited storage policy, transition times, shared units, and deterministic and fixed data in the given time horizon. The different batch operations are modeled using state-task network representation. Two different mathematical formulations are proposed based on discrete- and continuous-time representations leading to a mixed-integer linear programming model which is solved using General Algebraic Modeling System software. A case study based on a real facility is presented to illustrate the potential and applicability of the proposed models. The continuous-time model required less number of events and has a smaller problem size compared to the discrete-time model. © 2014 American Institute of Chemical Engineers.
In Switzerland, the chemical, pharma and biotech industries make a substantial and sustained contribution to the Swiss economy. The company members of scienceindustries employ around 70,000 people in Switzerland. Since 1980 value creation and productivity have increased markedly. As a result the share of the Swiss gross value added has grown continually to reach 5.6% in 2015. Exports have also increased. Today the chemical, pharma and biotech industry contributes around 45% of all Swiss exports and is therefore the largest Swiss export industry. This article describes the key requirements from the viewpoint of the chemical-pharma industry in order that Switzerland can continue to compete as an innovative location in global competition.

Full Text Available Abstract The development of agricultural biotechnology humanitarian projects for food security in the last five years has been rapid in developing countries and is expected to rise sharply over the coming years. An extremely critical issue in these projects involves building trust with the community and farmers they aim to serve. For the first time, our social audit engagement with one of these initiatives, the Water Efficient Maize for Africa project, has revealed that a critical but unrecognized component of building trust with farmers involves publicly addressing the concerns surrounding stacked trait crops. As a result, we argue in this article that it is critical to actively anticipate the concerns that could be raised over trait stacking by incorporating them into global access plans of such initiatives early in order to facilitate adoption, provide the best value to the small-scale farmer and gain trust with the community whom these projects aim to serve. This perspective, based on an actual international social audit, should be of value to scientists, funders and partners involved in biotech development initiatives for food security.

Plant biotechnology is founded on the principles of cellular totipotency and genetic transformation, which can be traced back to the Cell Theory of Matthias Jakob Schleiden and Theodor Schwann, and the discovery of genetic transformation in bacteria by Frederick Griffith, respectively. On the 25th anniversary of the genetic transformation of plants, this review provides a historical account of the evolution of the theoretical concepts and experimental strategies that led to the production and commercialization of biotech (transformed or transgenic) plants expressing many useful genes, and emphasizes the beneficial effects of plant biotechnology on food security, human health, the environment, and conservation of biodiversity. In so doing, it celebrates and pays tribute to the contributions of scores of scientists who laid the foundation of modern plant biotechnology by their bold and unconventional thinking and experimentation. It highlights also the many important lessons to be learnt from the fascinating history of plant biotechnology, the significance of history in science teaching and research, and warns against the danger of the growing trends of ignoring history and historical illiteracy.

Most of the genetically modified (GM) plants currently commercialized encompass a handful of crop species (soybean, corn, cotton and canola) with agronomic characters (traits) directed against some biotic stresses (pest resistance, herbicide tolerance or both) and created by multinational companies. The same crops with agronomic traits already on the market today will continue to be commercialized, but there will be also a wider range of species with combined traits. The timeframe anticipated for market release of the next biotech plants will not only depend on science progress in research and development (R&D) in laboratories and fields, but also primarily on how demanding regulatory requirements are in countries where marketing approvals are pending. Regulatory constraints, including environmental and health impact assessments, have increased significantly in the past decades, delaying approvals and increasing their costs. This has sometimes discouraged public research entities and small and medium size plant breeding companies from using biotechnology and given preference to other technologies, not as stringently regulated. Nevertheless, R&D programs are flourishing in developing countries, boosted by the necessity to meet the global challenges that are food security of a booming world population while mitigating climate change impacts. Biotechnology is an instrument at the service of these imperatives and a wide variety of plants are currently tested for their high yield despite biotic and abiotic stresses. Many plants with higher water or nitrogen use efficiency, tolerant to cold, salinity or water submergence are being developed. Food security is not only a question of quantity but also of quality of agricultural and food products, to be available and accessible for the ones who need it the most. Many biotech plants (especially staple food) are therefore being developed with nutritional traits, such as biofortification in vitamins and metals. The main

With a projected population of 10 billion by 2050, an immediate priority for agriculture is to achieve increased crop yields in a sustainable and cost-effective way. The concept of using a transgenic approach was realized in the mid-1990s with the commercial introduction of genetically modified (GM) crops. By 2010, the global value of the seed alone was US $11.2 billion, with commercial biotech maize, soya bean grain and cotton valued at approximately US $150 billion. In recent years, it has become evident that insect-resistant crops expressing δ-endotoxin genes from Bacillus thuringiensis have made a significant beneficial impact on global agriculture, not least in terms of pest reduction and improved quality. However, because of the potential for pest populations to evolve resistance, and owing to lack of effective control of homopteran pests, alternative strategies are being developed. Some of these are based on Bacillus spp. or other insect pathogens, while others are based on the use of plant- and animal-derived genes. However, if such approaches are to play a useful role in crop protection, it is desirable that they do not have a negative impact on beneficial organisms at higher trophic levels thus affecting the functioning of the agro-ecosystem. This widely held concern over the ecological impacts of GM crops has led to the extensive examination of the potential effects of a range of transgene proteins on non-target and beneficial insects. The findings to date with respect to both commercial and experimental GM crops expressing anti-insect genes are discussed here, with particular emphasis on insect predators and parasitoids.

Full Text Available Much research has been carried out on the accumulation and effective use of knowledge as a company-specific form of intellectual property. However, insufficient attention has been given to research focusing on the effects of micro-level knowledge absorption and its effective use. In this paper, we try to demonstrate what should be done in order to promote new biotech business from the perspective of each engineer’s knowledge, through a micro-level investigation focusing on the life science business section of one IT enterprise. Based on the results of a questionnaire survey of engineers, interviews of several engineers, and patent data analysis, we discuss the progress of the biotech business in an IT enterprise from the aspect of accumulation and circulation of knowledge in a core technology field, the IT business, and a technology field of new entry, the biotech business. This paper reports that the positive growth cycle of biotech business promotion in an IT enterprise, using Hitachi Software Engineering Co., Ltd. as a case, attained by incorporating the latest biotech knowledge from junior engineers and utilizing IT knowledge from middle engineers leads to the recruiting of qualified students.Keywords: accumulation and circulation of the knowledge, biotech business, open innovation, patent data analysis, questionnaire survey

Research-intensive small and medium-sized enterprises (SMEs) play a crucial role in the advancement of the biotechnology industry. This paper explored the impacts of internal and contextual variables on innovative activity in Korea and compared the results of this analysis with previous studies of other countries. Our analysis of 149 Korean biotech SMEs showed that the ratio of R&D expenditure to sales, the ratio of R&D employees to total employees, CEO characteristics, governmental support and international networking are positively correlated with a firm's innovation performance. The results may help decision makers to better foster SMEs in the Korean biotechnology industry.

This article has two objectives. It firstly provides a general framework for variables that influence R&D (Research and Development) localisation by pharmaceutical and biotech companies. The analysis of R&D localization includes both in-house R&D and contracted R&D. Following a systematic literature search, these variables were classified into four distinct categories: regulatory environment, institutional framework, national systems of innovation and local development and specialisation. The authors highlight that some of these factors directly depend on the action of public administrations (e.g., patent protection, price regulation, public investments in research, and incentives to private companies); others are indirectly influenced by public policies (e.g., GDP growth rate, infrastructures). This theoretical framework was used to analyse the Italian case-study. Pros and cons of the Italian context were investigated from the point of view of multinational pharmaceutical companies and the Italian Association of Biotech Companies. Interviews were chosen as the most appropriate data gathering technique given the exploratory nature of the study of the Italian context. The paper is divided into five parts. A brief introduction provides figures showing that Europe has been loosing positions compared with other Continents and the same has occurred in Italy compared with other EU countries. The second one illustrates the methodology. The third one is focused on variables affecting R&D localisation. In the fourth section the Italian case-study is discussed. Theoretical and empirical findings are summarised and discussed in the conclusions.

Significant research efforts have been undertaken in the last decade to develop specific cell-based therapies and, in particular, adult multipotent mesenchymal stem cells (MSCs) hold great promise toward such regenerative strategies. Bio-materials have been widely used in reconstructive bone surgery to heal critical-size bone defects due to trauma, tumor resection, and tissue degeneration. In particular, gelatin cryogel scaffolds are promising new biomaterials owing to their biocompatibility. There is an increasing demand for MSC-based regenerative approaches in the musculoskeletal system. Combining stem cells with biomaterial scaffolds provides a promising strategy for tissue engineering. Our previous studies showed the possibility to obtain MSCs from the human ovarian follicular liquid (FL) that is usually wasted during in vitro fertilization (IVF). In this study, we tested the ability of these FL cells to grow on gelatin cryogel in comparison with MSCs derived from human bone marrow. Samples and controls were analyzed with confocal and scanning electron microscopes. Results demonstrated that FL cells could grow on the biomaterial not only on the top but also in the layers below till 60 µm of deepness. Data suggested that the observed cells were mesenchymal since positive for vimentin and CD-44, typical MSC markers. Successful growth of putative MSCs derived from follicular liquid on 3D gelatin cryogel opens potential developments in biotech and medical applications.
Over the past forty years, microgravity has inspired and enabled applications in a wide range of sectors including medicine, materials, computers, communications, and national defense. Trends show that demand for high-tech solutions is increasing in these sectors, solutions that require higher resolution, greater precision, novel materials, innovative processes, and more sophisticated tools. These are areas where microgravity can offer unique capabilities for innovation. The Emerging Space Office (ESO) has engaged in multiple studies over the past year that have found that microgravity RD is one of the most promising technology areas for contributing to economic growth and to NASAs mission. The focus of these studies was on terrestrial markets rather than NASA applications, applied research rather than basic research, and commercial rather than academic investigators. There have been more success stories than are generally appreciated and there are significant areas of promising future potential. Many of the problems that have limited commercial microgravity development in the past are being solved. Microgravity research and development (RD) requires iteration and learning, as rapidly as possible. New technologies enable high throughput and rapid data collection in increasingly small payloads. The International Space Station is in orbit and provides a laboratory that is available 247 at least until 2024. Frequent flights by commercial space providers to and from the ISS now enable the fast learning cycles needed by high-tech industries. Launch costs are decreasing and the ability to return payloads to Earth is increasing. New commercial space laboratories, such as those being developed by SpaceX and Bigelow Aerospace, are in the final stages of development and testing. This ecosystem for microgravity RD has never been available before. These are game-changer conditions for attracting high-tech industries to space for terrestrial, as well as NASA, applications. However, few know that these capabilities are available or how to use them. In aggregate, the potential value for new applications from microgravity RD over the next ten years could add billions of dollars per year in terrestrial applications to the future economy, create new jobs, and generate a wide range of public benefits in medical advances, while broadening the customer base for the emerging space industry.
Jeremy Rifkin has petitioned a U.S. district court, the National Institutes of Health, and the Environmental Protection Agency in a campaign to prevent private companies, as well as universities, from releasing genetically modified organisms into the environment until the possible environmental impact of these experiments has been analyzed. Rifkin is seeking to stop Advanced Genetic Sciences and Cetus Corporation from conducting field tests respectively of modified frost-resistant bacteria and disease-resistant plants. His efforts have already led scientists at Stanford University to postpone voluntarily the planting of corn seed containing recombinant DNA.

Full Text Available Recently, the intended positive effects of the current patent system in biotechnological research have been widely questioned. As part of this review, it is discussed here one of the foundations of the model. The assumption of the indispensability of patents is examined through the analysis of their expected benefits; namely, that patents are suitable to ensure access to information, access to and use of inventions and, finally, that they should promote both creativity and research. Applied to synthetic biology, in spite of newly discovered techniques and promising products, this approach reveals that this discipline also encounters similar issues. However, it also offers a new vision of intellectual property rights and their effects on research, which is based on a different conception of the commons and its relationship with private ownership of intangible assets in the knowledge economy.

VitaResc (formerly Apex) is developing PHP-HT, pyridoxalated hemoglobin polyoxyethylene conjugate, for the potential treatment of nitric oxide-induced shock (characterized by hypotension), associated with various etiologies, initially in septic shock. A phase I safety study and an initial phase I/II patient trial for NO-induced shock have been completed, and VitaResc has enrolled patients in three of five planned cohorts in a continuation of these trials to include a protocol of continuous infusion and dose escalation [330680,349187,390918]. The results from the dose escalation trials are expected to provide the basis for a randomized, controlled phase II/III pivotal trial of PHP-HT . VitaResc has licensed PHP-HT exclusively from Ajinomoto for all indications, worldwide, except Japan . Ajinomoto originally developed the human derived and chemically modified hemoglobin preparation as a blood substitute, but no development has been reported by the company since 1997 [275277,303577]. The other potential indications of PHP-HT include shock associated with burns, pancreatitis, hemodialysis and cytokine therapies . VitaResc expects the annual market potential of PHP-HT to exceed 1 billion dollars .

The world of biotechnology "start-ups" and entrepreneurship offers exciting new avenues for driving state-of-the-art research using an arsenal of multidisciplinary skills, whether your role is as part of a team or as a leader. Although traditionally these positions may not be as secure as those offered by some of the larger companies, the small start-up culture provides opportunities for contributing at many levels to a wide range of responsibilities: from scientific discovery to delivery of proof of concept and intellectual property; from analysis of market opportunities and competitive intelligence to creation of time lines and business plans for a first product. Often, if you get in on the ground level, you get to validate your own concept, pitch to potential investors, argue value, build a team, engage advisors, and then, with funding in hand, launch an entirely new research and development (R&D) enterprise. Many of the skills and much of the experience gained while pursuing a graduate degree can be put to good use in these arenas as well. This path, however, is not for the faint of heart; it requires not only a strong scientific background and organizational skills, but also the ability to work well on a team, excellent communication skills, and persistence when faced with delays or disappointment. With increasing responsibilities in the small company come the requirements for aptitudes for leadership, strategic and financial planning, networking, negotiating, and managing both projects and personnel.

Appropriate negotiation and drafting of license agreements are critical to successfully establishing and managing the expansive and complex relationships that are becoming more common between industry and universities. More often than not, the resulting licensing agreements become quite lengthy and complex, and the key principles become difficult to discern among all the details. This summary provides a short, nonexhaustive introduction to some of the essential components of these licenses with the intent of providing the non-licensing professional a better appreciation of some of the key commercial and legal terms from both an academic and company perspective, keeping in mind some of the considerations that particularly apply to biotechnology deals.

For class II, type A2 biological safety cabinets (BSC), NSF/ANSI Standard 49 should be conformed in cabinet airflow velocity derivation, particle contamination, and aerodynamic flow properties. However, there exists a potential problem. It has been built that the cabinet air flow stabilize is influenced by the quantity of downflow of air and the height above the cabinet exhaust opening. Three air downflow quantities were compared as an operating apparatus was placed from 20 to 40 cm above the bench of the cabinet. The results show that the BSC air downflow velocity is a function of increased sampling height, displaying that containment is improvingly permitted over product protection as the sampling height decreases. This study investigated the concentration gradient of particles at various heights and downflow air quantity from the bench of the BSC. Experiment results indicate that performance near the bench was better than in the rest of the BSC. In terms of height, the best cleanliness was measured at a height of 10 cm over the bench; it reduced actually with add in height. The empirical curves accommodate, founded on the concentration gradient of particle created was elaborated for evaluating the particle concentration at different heights and downflow air quantity from the source of the bench of the BSC. The particle image velocimetry system applied for BSC airflow research to fix amount of airflow patterns and air distribution measurement and results of measurements show how obstructions can greatly influence the airflow and contaminant transportation in a BSC.

Start-up companies in the biotechnology and medical device sectors are important sources of health care innovation. This paper describes the role of venture capital in supporting these companies and charts the growth in venture capital financial support. The paper then uses longitudinal data to describe market entry and exit by these companies. Similar factors are associated with entry and exit in the two sectors. Entries and exits in one sector also appear to influence entry in the other. These findings have important implications for developing innovative technologies and ensuring competitive markets in the life sciences.
On 30 December 2008, the Regulation (EC) 1394/2007 on advanced therapy medicinal products (ATMPs) entered into force. Herewith the first EU-wide regulatory framework for ATMPs was established. It requires a central marketing authorisation application to the EMA (European Medicinal Agency). This new framework especially changes the code of regulatory practice for tissue engineered products (TEPs), as no registration procedure had been previously required for autologous TEPs. This also meant that no clinical proof of efficacy achieved by a pivotal clinical trial was necessary. Difficulties and their background as well as the vast requirements for product development that have to be addressed by small companies within a very short time frame are presented. Hereby, it is obvious that regulatory experience which is required to identify and implement the resulting implications was not in place yet and still had to be established. The lack of regulatory experience also resulted in difficulties with scientific advice preparation, expectations toward regulatory agencies, consultants, and transformation of regulatory requirements. Addressing the regulatory requirements within the transition period is even more difficult for entrepreneurs with products which are assigned for indications resulting in complex challenges to the trial design. Due to the enormous time pressure to generate data and due to the implied financial pressure, different adaptation strategies are evolving. In Germany the "hospital exemption" according to §4b AMG (German Medicinal Products Law) is of major importance. A reorientation toward acellular products and a slow down in development of new ATMP products is expected.

The design of screening methods for the detection of genetically modified organisms (GMOs) in food would improve the efficiency in their control. We report here a PCR amplification method combined with a sequence-specific electrochemical genosensor for the quantification of a DNA sequence characteristic of the 35S promoter derived from the cauliflower mosaic virus (CaMV). Specifically, we employ a genosensor constructed by chemisorption of a thiolated capture probe and p-aminothiophenol gold surfaces to entrap on the sensing layer the unpurified PCR amplicons, together with a signaling probe labeled with fluorescein. The proposed test allows for the determination of a transgene copy number in both hemizygous (maize MON810 trait) and homozygous (soybean GTS40-3-2) transformed plants, and exhibits a limit of quantification of at least 0.25% for both kinds of GMO lines.

Synthetic biology aims to apply engineering principles to the design and modification of biological systems and to the construction of biological parts and devices. The ability to programme cells by providing new instructions written in DNA is a foundational technology of the field. Large-scale de novo DNA synthesis has accelerated synthetic biology by offering custom-made molecules at ever decreasing costs. However, for large fragments and for experiments in which libraries of DNA sequences are assembled in different combinations, assembly in the laboratory is still desirable. Biological assembly standards allow DNA parts, even those from multiple laboratories and experiments, to be assembled together using the same reagents and protocols. The adoption of such standards for plant synthetic biology has been cohesive for the plant science community, facilitating the application of genome editing technologies to plant systems and streamlining progress in large-scale, multi-laboratory bioengineering projects. © 2016 The Author(s). published by Portland Press Limited on behalf of the Biochemical Society.

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.

Full Text Available Abstract Background Agricultural biotechnology public-private partnerships (PPPs have been recognized as having great potential in improving agricultural productivity and increasing food production in sub-Saharan Africa. However, there is much public skepticism about the use of GM (genetically modified crops and suspicion about private sector involvement in agbiotech projects. This case study sought to understand the role of trust in the Bacillus thuringiensis (Bt cotton in Burkina Faso project by exploring practices and challenges associated with trust-building, and determining what makes these practices effective from the perspective of multiple stakeholders. Methods We conducted semi-structured, face-to-face interviews to obtain stakeholders’ understanding of trust in general as well as in the context of agbiotech PPPs. Relevant documents and articles were analyzed to generate descriptions of how trust was operationalized in this evolving agbiotech PPP. Data was analyzed based on emergent themes to create a comprehensive narrative on how trust is understood and built among the partners and with the community. Results We derived four key lessons from our findings. First, strong collaboration between research, industry and farmers greatly contributes to both the success of, and fostering of trust in, the partnership. Second, this case study also revealed the important, though often unrecognized, role of researchers as players in the communication strategy of the project. Third, effective and comprehensive communication takes into account issues such as illiteracy and diversity. Fourth, follow-up at the field level and the need for a multifaceted communications strategy is important for helping push the project forward. Conclusions Burkina Faso’s well-established and effective cotton selling system laid the foundation for the implementation of the Bt cotton project – particularly, the strong dialogue and the receptivity to collaboration. Interviewees reported that establishing and maintaining trust among partners, researchers and the community in Burkina Faso greatly contributed to the success of the PPP. By addressing challenges to building trust and engaging in trust-building practices early on, improvements in the effectiveness of agbiotech PPPs are likely.

Genetically modified (GM) technique, one of the modern biomolecular engineering technologies, has been deemed as profitable strategy to fight against global starvation. Yet rapid and reliable analytical method is deficient to evaluate the quality and potential risk of such resulting GM products. We herein present a biomolecular analytical system constructed with distinct biochemical activities to expedite the computational detection of genetically modified organisms (GMOs). The computational mechanism provides an alternative to the complex procedures commonly involved in the screening of GMOs. Given that the bioanalytical system is capable of processing promoter, coding and species genes, affirmative interpretations succeed to identify specified GM event in terms of both electrochemical and optical fashions. The biomolecular computational assay exhibits detection capability of genetically modified DNA below sub-nanomolar level and is found interference-free by abundant coexistence of non-GM DNA. This bioanalytical system, furthermore, sophisticates in array fashion operating multiplex screening against variable GM events. Such a biomolecular computational assay and biosensor holds great promise for rapid, cost-effective, and high-fidelity screening of GMO. Copyright © 2013 Elsevier B.V. All rights reserved.

After utilizing robots for more than 30 years for classic industrial automation applications, service robots form a constantly increasing market, although the big breakthrough is still awaited. Our approach to service robots was driven by the idea of supporting lab personnel in a biotechnology laboratory. After initial development in Germany, a mobile robot platform extended with an industrial manipulator and the necessary sensors for indoor localization and object manipulation, has been shipped to Bayer HealthCare in Berkeley, CA, USA, a global player in the sector of biopharmaceutical products, located in the San Francisco bay area. The determined goal of the mobile manipulator is to support the off-shift staff to carry out completely autonomous or guided, remote controlled lab walkthroughs, which we implement utilizing a recent development of our computer vision group: OpenTL - an integrated framework for model-based visual tracking.

Changes in the economics of product development resulting from heightened safety regulations could have a sizable negative impact on drug and biotechnology companies' decisions about investing in innovation. We developed a model to compare the potential economic effects of pre- and postmarketing strategies to identify safety problems with new drugs. Although expanding Phase III clinical testing and postmarketing safety surveillance are not perfect substitutes, our findings suggest that even a large increase in funding for the latter will have a relatively small adverse impact on investment decisions by drug companies and venture capital firms, compared with the former.

Innovative high-tech small and medium sized enterprises (SMEs) are thought to be drivers of economic renewal and growth. However, due to their limited size, SMEs face two fundamental innovation barriers: the risk that other organizations appropriate the returns to the newly created knowledge by SMEs (knowledge leakage), and a lack of understanding and recognition of their business on the part of potential stakeholders (legitimacy deficits). Based on a panel study of 196 SMEs this paper shows ...

Several barriers limit the development of vaccines against sexually transmitted diseases (STIs). Critical scientific information is missing that makes the feasibility and the likelihood of success of vaccines against genital herpes, chlamydia, gonorrhea and trichomonas uncertain: the immunity induced by natural infection is absent or imperfect which seriously limits the capacity to define the types of immune responses that an effective vaccine must induce. Reliable animal models are lacking and a number of crucial clinical questions are still unanswered about the goal of these vaccines and definition of endpoints for clinical trials. In the absence of a clear recognition of the need for vaccines against these diseases, there is no motivation for public or private research and industry to invest in the development of vaccines against STIs. The STI burden should be evaluated not only in terms of mortality and morbidity, but also in terms of economic and psycho-social impact. A global public-private consortium could mobilize the joint efforts of all stakeholders involved in the research, development and implementation of STI vaccines of the public and private sectors; ensure that sufficient resources are applied to R&D of vaccines against these STIs; and provide the pull-push forces that are necessary to overcome the barriers to develop safe and effective vaccines against these diseases.

There has been increased concern that the current "blockbuster" model of drug discovery and development practiced by "Big Pharma" are unsustainable in terms of cost (> $1 billion/approved drug) and time to market (10 - 15 years). The recent mergers and acquisitions (M&A), shuttering of internal research programs, closure of "redundant" sites of operations, senior management turnover and continued workforce reductions among the top 10 major pharmaceutical companies reflect draconian responses to reduce costs. However, the resultant exodus of intellectual capital, loss in motivation and momentum, and exit from early stage discovery programs by pharmaceutical companies has contributed to an "innovation deficit". Disease advocacy groups, investment communities and the government are calling for new innovative business models to address this deficit. In particular they are looking towards academia and clinical trials centers to catalyze new innovations in translational research. Indeed over the last decade many academic institutions have launched drug discovery centers largely comprising high-throughput screening (HTS) to accelerate "translational" research. A major impetus for this "open innovation" effort has been the National Institutes of Health (NIH) "Roadmap" and Molecular Libraries Initiative/Program (MLI/MLP), which is in its last year, and will be transitioned into the National Center for the Advancement of Translational Sciences (NCATS). With the end of Roadmap funding, general reduction in Federal government funding and its recent sequestration, academic drug discovery centers are being challenged to become selfsustaining, adding financial value, while remaining aligned with the missions of their respective academic non-profit institutions. We describe herein, a brief history of our bi-coastal Conrad Prebys Center for Chemical Genomics (Prebys Center) at the Sanford|Burnham Medical Research Institute (SBMRI), the key components of its infrastructure, core competencies of its fully integrated drug discovery expertise, best practices adopted in our day-to-day operations, and finally some of our current funding and collaboration and/or strategic alliance models for pre-competitive drug discovery with other academic/clinical partners, other governmental agencies, and with pharmaceutical and biotechnology companies.

US common law recites a natural law, natural phenomenon or abstract idea as exceptions to the 4 statutory patentable categories to guard against the wholesale preemption of fundamental principles. The very recent evolutions of patent exceptions in the US may increase the difficulty of patenting and may create uncertainty in determining patent eligibility. To solve the thorny problem of eligibility, this study presents a flow chart based on the courts’ decisions that can serve as a set of guidelines for determining patent eligibility. A case related to prostate cancer immune therapy is presented for discussion. PMID:25714661

Full Text Available Abstract Pharmaceutical industry consolidation and overall research downsizing threatens the ability of companies to benefit from their previous investments in translational research as key leaders with the most knowledge of the successful use of biomarkers and translational pharmacology models are laid off or accept their severance packages. Two recently published books may help to preserve this type of knowledge but much of this type of information is not in the public domain. Here we propose the creation of a translational medicine knowledge repository where companies can submit their translational research data and access similar data from other companies in a precompetitive environment. This searchable repository would become an invaluable resource for translational scientists and drug developers that could speed and reduce the cost of new drug development.

Globally, biotech crops have left a legacy of success and some notable failures due to regulatory and litigious barriers to entry, with a pipeline of potentially beneficial biotech agricultural products lined up and awaiting approval. Compared with traditional agriculture, these crops provide significant health benefits to environmental and human health benefits, including organic systems. While the rest of the world has increased acreage of biotech crops at a steady annual rate of 10%, North America-the birthplace of most biotech crops-has reached a critical turning point in its regulatory evolution. Biotech crops can play a major role in creating a more sustainable agricultural landscape, which is increasingly well-documented, but future commercial use may be hampered by regulation and litigation that place organic and non-GMO agriculture on a pedestal, which could force many biotech crops into containment. If producers of biotech crops are required to prevent their crops from contaminating these other, high premium specialty crops through migration, innovation in agricultural biotechnology will suffer (as the European experience with agricultural biotechnology clearly demonstrates).

Genetically modified (GM) foods are currently a controversial topic about which the lay public in the United States knows little. Formative research has demonstrated that the lay public is uncertain and concerned about GM foods. This study (N = 858) extends focus group research by using the Theory of Reasoned Action (TRA) to examine attitudes and subjective norms related to GM foods as a theoretical strategy for audience segmentation. A hierarchical cluster analysis revealed four unique audiences based on their attitude and subjective norm toward GM foods (ambivalent-biotech, antibiotech, biotech-normer, and biotech individual). Results are discussed in terms of the theoretical and practical significance for audience segmentation.

The direct-to-consumer marketing of unproven stem cell interventions (SCIs) is a serious public health concern. Regulations and education have had modest impact, indicating that different actors must play a role to stop this unfettered market. We consider the role of the biotech industry in tackling unproven SCIs. Grounded in the concept of corporate social responsibility, we argue that biotech companies should screen consumers to ensure that products and services are being used appropriately and educate employees about unproven SCIs. © 2017 ASCPT.

Monsanto Co. has developed two sweet corn hybrids, MON 88017 and MON 89034, that contain biotechnology-derived (biotech) traits designed to enhance sustainability and improve agronomic practices. MON 88017 confers benefits of glyphosate tolerance and protection against corn rootworm. MON 89034 provides protection against European corn borer and other lepidopteran insect pests. The purpose of this assessment was to compare the kernel compositions of MON 88017 and MON 89034 sweet corn with that of a conventional control that has a genetic background similar to the biotech sweet corn but does not express the biotechnology-derived traits. The sweet corn samples were grown at five replicated sites in the United States during the 2010 growing season and the conventional hybrid and 17 reference hybrids were grown concurrently to provide an estimate of natural variability for all assessed components. The compositional analysis included proximates, fibers, amino acids, sugars, vitamins, minerals, and selected metabolites. Results highlighted that MON 88017 and MON 89034 sweet corns were compositionally equivalent to the conventional control and that levels of the components essential to the desired properties of sweet corn, such as sugars and vitamins, were more affected by growing environment than the biotech traits. In summary, the benefits of biotech traits can be incorporated into sweet corn with no adverse effects on nutritional quality.

Wheat straw was fermented by Crinipellis sp. RCK-1, a lignin degrading fungus, under solid state fermentation conditions. The fungus degraded 18.38% lignin at the expense of 10.37% cellulose within 9 days. However, when wheat straw fermented for different duration was evaluated in vitro, the 5 day fungal fermented wheat straw called here “Biotech Feed” was found to possess 36.74% organic matter digestibility (OMD) and 5.38 (MJ/Kg Dry matter) metabolizable energy (ME). The Biotech Feed was also observed to be significantly enriched with essential amino acids and fungal protein by fungal fermentation, eventually increasing its nutritional value. The Biotech Feed upon in vitro analysis showed potential to replace 50% grain from concentrate mixture. Further, the calves fed on Biotech Feed based diets exhibited significantly higher (pintake (DMI: 3.74 Kg/d), dry matter digestibility (DMD: 57.82%), total digestible nutrients (TDN: 54.76%) and comparatively gained 50 g more daily body weight.

The intent of this project was to expand Northern Virginia Community College's capability to offer training to support the Biotechnology Industry in the northern Virginia region. The general goal of this project was to create a College Biotechnology Program; specific goals of the project were to a) design curricula/courses to prepare students to become entry-level lab technicians, b) redesign and equip lab space to better suit the needs of the program, c) develop partnerships with the local industry through outreach and the formation on an advisory board, d) recruit students into the program, and e) provide instructional support for local high school teachers. At the end of the grant period, NOVA has successfully created two new curricula in biotechnology: an Associate of Applied Science (A.A.S.) in Biotechnology (initiated in Fall 2008) and a Career Studies Certificate for Biotechnology Lab Technicians (to be initiated in Fall 2010). These curricula were designed with advice from an external advisory committee which is comprised of representatives from industry, transfer institutions and high school administrators. To date, almost all courses have been designed and piloted; the equipment needed for the courses and the initial supplies were paid for by the grant as was the re-modeling of some lab space to be used for the biotech courses. In order to market the program, the NOVA Biotech Program has also established relationships with the local high schools. Presentations were given at several local high schools and on-site workshops were held for high school students and teachers. As a result, close to 1000 students have attended program open houses, presentations within the high schools, or workshops held in the summer. Over 100 teachers have received information and/or training in biotechnology. These outreach efforts as well as high quality curricula have started to attract a number of students to the program – for example, there are currently 70 students

As the two leading markets for pharmaceutical and biotech companies, the USA and Europe offer incentives to stimulate drug innovation, including patent and regulatory exclusivities. These exclusivities extend periods during which companies can market their products free of generic or other competition and recoup their investment. Pharmaceutical and biotech companies should carefully assess the different types of exclusivities available when developing regulatory submissions, patent filing strategies. The authors have previously summarized the USA exclusivities in an earlier publication. This article focuses on European exclusivities. Due to space limitations, it focuses on small molecule drugs. Analogously to the format previously used, we have provided a cheat sheet of European exclusivities for small molecule drugs in Figure 1 .
Industrial biotechnology has not developed as fast as expected due to some challenges including the emergences of alternative energy sources, especially shale gas, natural gas hydrate (or gas hydrate) and sand oil et al. The weaknesses of microbial or enzymatic processes compared with the chemical processing also make industrial biotech products less competitive with the chemical ones. However, many opportunities are still there if industrial biotech processes can be as similar as the chemical ones. Taking advantages of the molecular biology and synthetic biology methods as well as changing process patterns, we can develop bioprocesses as competitive as chemical ones, these including the minimized cells, open and continuous fermentation processes et al. PMID:22905695
Although the global area of biotech crops continues to climb for the tenth consecutive year at a sustainable double-digit growth rate, the acceptance of biotech products from agriculture in Europe is still low. There is a gap between science and perception. It is a strong belief that the public turning against science and against GM food has been encouraged by the negative activities of NGO groups. Scientists have to overcome the purely risk-based discussion, and the benefits of plant biotechnology have to be made literally visible. GM food should be available, the benefits should be tangible and the consumer should have fun with such novel food. The gap could be reduced if genetically modified plants and the products thereof were regulated in the same way as classical products.

as the negotiation of a preexisting science-industry boundary. Rather, viability is obtained through a strategy of circumventing the science-industry food chain and sequestering biotech components within the research center. Symbiosis allows academic scientists to do biology while at the same time demonstrating......Whether celebratory or critical, STS research on science-industry relations has focused on the blurring of boundaries and hybridization of codes and practices. However, the vocabulary of boundary and hybrid tends to reify science and industry as separate in the attempt to map their relation....... Drawing on interviews with the head of a research center in plant biology, this article argues that biology and biotech are symbionts. In order to be viable and productive, symbiosis needs to be carefully managed and given room for divergence within mutual dependence. This process does not take place...

Strategic alliances in product development and marketing are crucial to the biotechnology industry. Many alliances, however, are terminated before the drug reaches the market. In this article we make the case that strategic alliances can fail because of how they are negotiated. Alliance contracts are often inflexible and do not allow for changes in market conditions. We propose a model for contract valuation that can assist biotech and/or pharma deal makers in negotiating alliances that have a higher chance of survival in uncertain market conditions. The model makes use of variable royalties and milestone payments. Because licensing is key to the biotech and/or pharma business model this article will be of interest not only to professionals in licensing, but to all professionals active in the industry.

Full Text Available This paper examines the governance of property rights on genetically modified (GM soybean seeds. Specifically, the article undertakes a comparative analysis on the collection of royalties in GM soybean seeds in the U.S. and Brazil. For each country, the authors describe the regulatory framework governing the protection of biotechnology innovations in agriculture and investigate the mechanisms of royalty collection in GM soybean seeds. The paper also offers econometric evidence linking the capture of value on biotech innovations and the protection mechanisms deployed by biotech firms. The results suggest that, subject to the institutional environment, firms may choose to transact a GM attribute separated from the seed, building specialized governance structures framed around the genetic attribute and not around the seed as a whole.

Small biotech companies have been an important source of innovation, pipelines, and new products for the pharmaceutical industry, and are primarily financed by venture capital (VC). The significant changes happening within the VC industry have broad implications for these small companies. This includes a shift to financing later-stage programs with increasing interest in orphan or specialty indications. Nontraditional sources of capital and innovative risk-sharing structures can enable early-stage companies.

This article explores the legal meanings of biopiracy concept, linked to subjects such as intellectual property rights on genetic resources, bioprospecting contracts, right to food, and food security. It overcomes the critical function of biopiracy concept related to world-wide extended tendencies: privatization and technification. Likewise, protectionism shows the opportunity that biopiracy concept represents for the enrichment of the legal interpretation related to the bioethical statue of biotech developments.

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.

Uncertainty surrounding the risk and reward of investments in biopharmaceutical companies poses a challenge to those interested in funding such enterprises. Using data on publicly traded stocks, we track the performance of 1,066 biopharmaceutical companies from 1930 to 2015-the most comprehensive financial analysis of this sector to date. Our systematic exploration of methods for distinguishing biotech and pharmaceutical companies yields a dynamic, more accurate classification method. We find that the performance of the biotech sector is highly sensitive to the presence of a few outlier companies, and confirm that nearly all biotech companies are loss-making enterprises, exhibiting high stock volatility. In contrast, since 2000, pharmaceutical companies have become increasingly profitable, with risk-adjusted returns consistently outperforming the market. The performance of all biopharmaceutical companies is subject not only to factors arising from their drug pipelines (idiosyncratic risk), but also from general economic conditions (systematic risk). The risk associated with returns has profound implications both for patterns of investment and for funding innovation in biomedical R&D.

Indian Biotech opponents have attributed the increase of suicides to the monopolization of GM seeds, centering on patent control, application of terminator technology, marketing strategy, and increased production costs. The contentions of the biotech opponents, however, have been criticized for a lack of transparency in their modus operandi i.e. the use of methodology in their argumentation. The fact is, however, that with the intention of getting the attention of those capable of determining the future of GM cotton in India, opponents resorted to generating controversies. Therefore, this article will review and evaluate the multifaceted contentions of both opponents and defenders. Although the association between seed monopolization and farmer-suicide is debatable, we will show that there is a link between the economic factors associated with Bt. cultivation and farmer suicide. The underlying thesis of biotech opponents becomes all the more significant when analysed vis-à-vis the contention of the globalization critics that there has been a political and economic marginalization of the Indian farmers. Their accusation assumes significance in the context of a fragile democracy like India where market forces are accorded precedence over farmers' needs until election time.

The principles of quality by design (QbD) have been applied in cell culture manufacturing process development and characterization in the biotech industry. Here we share our approach and practice in developing and characterizing a cell culture manufacturing process using QbD principles for establishing a process control strategy. Process development and characterization start with critical quality attribute identification, followed by process parameter and incoming raw material risk assessment, design of experiment, and process parameter classification, and conclude with a design space construction. Finally, a rational process control strategy is established and documented.

In considering new directions for low gravity research with particular regard to broadening the number and types of industrial involvements, it is noted that transport phenomena play a vital role in diverse processes in the chemical, pharmaceutical, food, and biotech industries. Relatively little attention has been given to the role of gravity in such processes. Accordingly, numerous industrial processes and phenomena are identified which involve gravity and/or surface tension forces. Phase separations and mixing are examples that will be significantly different in low gravity conditions. A basis is presented for expanding the scope of the low gravity research program and the potential benefits of such research is indicated.
Biotech may have less to fear from Rifkin than from its own inclination to dismiss the fact that the evolution of ethics and patent laws applying to patenting genes has been haphazard. Perhaps it is time for the biotechnology industry to get behind the establishment of an effective forum for opening much-needed dialogue. Perhaps a Senate proposal to establish a bioethics commission, which reportedly has bogged down in partisan politics, is just such a venue for the government and private sector to begin to hash out the ethical and legal dilemmas that are indisputably at the heart of the biotechnology industry, and its future success.

Full Text Available The 2010 Beltwide Cotton Conferences provided a new vision of the consequences of about 15 years of widespread and uncoordinated cropping of transgenic cotton in the United States. Insect-resistant and/or herbicide-tolerant cotton varieties modified parasite complexes, namely those of insects and weeds damaging cotton crops. The Conferences have revealed that the adaptation solutions so far proposed make illusory the expectations at the launch of transgenic cotton, in terms of effective pest control, cost reduction, and antagonism between chemical and biotech methods. The USA case points out that the technical and economic sustainability of transgenic varieties must lie in a systemic and coordinated approach.

The unique advantages such as brightness, non-photobleaching, good bio-compatibility make gold nanoparticles desirable labels and play important roles in biotech and related research and applications. Distinguishing gold nanoparticles from other dielectric scattering particles is of more importance, especially in bio-tracing and imaging. The enhancement image results from the localized surface plasmon resonance associated with gold nanopartilces makes themselves distinguishable from other dielectric particles, based on which, we propose a dual-wavelength detection method by employing a high sensitive cross-polarization microscopy.

Biotech news coverage in English-language Russian media fits the profile of the Russian information warfare strategy described in recent military reports. This raises the question of whether Russia views the dissemination of anti-GMO information as just one of many divisive issues it can exploit as part of its information war, or if GMOs serve more expansive disruptive purposes. Distinctive patterns in Russian news provide evidence of a coordinated information campaign that could turn public opinion against genetic engineering. The recent branding of Russian agriculture as the ecologically clean alternative to genetically engineered foods is suggestive of an economic motive behind the information campaign against western biotechnologies.

Innovation in medicine requires unique partnerships between academic research, biotech or pharmaceutical companies, and health-care providers. While innovation in medicine has greatly increased over the past 100 years, innovation in wound care has been slow, despite the fact that chronic wounds are a global health challenge where there is a need for technical, process and social innovation. While novel partnerships between research and the health-care system have been created, we still have much to learn about wound care and the wound-healing processes.

However, the vocabulary of boundary and hybrid tends to reify science and industry as separate in the attempt to map their relation...... as the negotiation of a preexisting science-industry boundary. Rather, viability is obtained through a strategy of "circumventing" the science-industry food chain and "sequestering" biotech components within the research center.

The objective of this work is to elucidate various essential drugs in the Brazil, Russia, India, China and South Africa (BRICS) countries. It discusses the opportunities and challenges of the existing biotech infrastructure and the production of drugs and vaccines in member states of the BRICS. This research is based on a systematic literature review between the years 2000 and 2014 of documents retrieved from the databases Embase, PubMed/Medline, Global Health, and Google Scholar, and the websites of relevant international organizations, research institutions and philanthropic organizations. Findings vary from one member state to another. These include useful comparison between the BRICS countries in terms of pharmaceuticals expenditure versus total health expenditure, local manufacturing of drugs/vaccines using technology and know-how transferred from developed countries, and biotech entrepreneurial collaborations under the umbrella of the BRICS region. This study concludes by providing recommendations to support more of inter collaborations among the BRICS countries as well as between BRICS and many developing countries to shrink drug production costs. In addition, this collaboration would also culminate in reaching out to poor countries that are not able to provide their communities and patients with cost-effective essential medicines.

Full Text Available Introduction: The efficacy and safety in treatment with oral anticoagulants are dependent on the monitoring of the effect of anticoagulants by the prothrombin time (PT. The system INR (International Normalized Ratio was developed to minimize the variability in the PT, mainly because of the thromboplastin reagent used. Objective: Compare the results of INR employing six thromboplastins and plasmas of patients using oral anticoagulants. Materials and Methods: For this study, 96 patients using oral anticoagulants and that had TP collected for monitoring anticoagulants were selected randomly. INR values were determined using six commercially available thromboplastin brands. Results and Discussion: Of the 96 patients, 29 were with the INR between 2 and 3 when used reagents Dade-Behring®, Human do Brasil® and Diagnostica Stago®. Regardless of the range of INR, the results obtained with the reagent Labtest® were statistically different from the Dade-Behring®, from Diagnostica Stago®, Trinity Biotech and Bios Diagnostica®. With INR between 2 and 3 only differences were observed between the results of brands and Bios Diagnostica® Labtest®. With INR above 3, the results of Labtest® were different from the Dade-Behring®, from Diagnostica Stago®, Trinity Biotech® and Bios Diagnostica®. Conclusion: Despite the establishment of INR, there are still significant differences in INR results depending on the thromboplastin brand used, which can interfere with the therapeutic approach in relation to oral anticoagulants.

Full Text Available Abstract The major scientific advances of the last century featured the identification of the structure of DNA, the development of molecular biology and the technology to exploit these advances. These breakthroughs gave us new tools for crop improvement, including molecular marker-aided selection (MAS and genetic modification (GM. MAS improves the efficiency of breeding programs, and GM allows us to accomplish breeding objectives not possible through conventional breeding approaches. MAS is not controversial and is now routinely used in crop improvement programs. However, the international debate about the application of genetic manipulation to crop improvement has slowed the adoption of GM crops in developing as well as in European countries. Since GM crops were first introduced to global agriculture in 1996, Clive James has published annual reports on the global status of commercialized GM crops as well as special reports on individual GM crops for The International Service for the Acquisition of Agri-biotech Applications (ISAAA. His 34th report, Global Status of Commercialized Biotech/ GM crops: 2011  is essential reading for those who are concerned about world food security.
Full Text Available The biological diversity contributes to many aspects of human well-being and ecosystem function, however, we have known very little about microbial diversity due to the limitations of appropriate methodology underneath it. The development of biotech have brought revolutionary progress in the study of microbial diversity in which Biolog required to pay a lot of attention due to its ability of reflecting the metabolic situation of living microbial communities and have used widely in the study of soil microbial communities. However, there are some controversies during its operation procedure and incubation process, handling large data during the analysis might have also caused trouble in the overall process. The approach based on uses of “absolute used”, “INDIRECT” function in Excel could greatly optimize the data analysis, and the increase of principle components in Principle Component Analysis (PCA were able to extract more information from original data. Besides, the method that through “Taylor” and “logic” transformation for original data before PCA analysis could achieve data analysis optimization. This paper have presented the applications and optimization of Biolog EcoPlates in studies of functional diversity of microbial communities, presented its inherent biases and prospects, provided some reference for the applications and popularization of Biolog EcoPlates for microbial study and finally, the results imply improving the knowledge of biotech in study of soil microbial functional diversity.

Therapeutic proteins show a rapid market growth. The relatively young biotech industry already represents 20 % of the total global pharma market. The biotech industry environment has traditionally been fast-pasted and intellectually stimulated. Nowadays the top ten best selling drugs are dominated by monoclonal antibodies (mABs).Despite mABs being the biggest medical breakthrough in the last 25 years, technical innovation does not stand still.The goal remains to preserve the benefits of a conventional mAB (serum half-life and specificity) whilst further improving efficacy and safety and to open new and better avenues for treating patients, e.g., improving the potency of molecules, target binding, tissue penetration, tailored pharmacokinetics, and reduced adverse effects or immunogenicity.The next generation of biopharmaceuticals can pose specific chemistry, manufacturing, and control (CMC) challenges. In contrast to conventional proteins, next-generation biopharmaceuticals often require lyophilization of the final drug product to ensure storage stability over shelf-life time. In addition, next-generation biopharmaceuticals require analytical methods that cover different ways of possible degradation patterns and pathways, and product development is a long way from being straight forward. The element of "prior knowledge" does not exist equally for most novel formats compared to antibodies, and thus the assessment of critical quality attributes (CQAs) and the definition of CQA assessment criteria and specifications is difficult, especially in early-stage development.

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.

A few years ago, we assisted in the demonstration for the first time of the revolutionary idea of a type of adaptive-immune system in the bacteria kingdom. This system, named CRISPR, and variants engineered in the lab, have been demonstrated as functional with extremely high frequency and fidelity in almost all eukaryotic cells studied to date. The capabilities of this RNA-guided nuclease have added to the interest that was announced with the advent of previous technologies for genome editing tools, such as ZFN and TALEN. The capabilities exhibited by these gene editors, opens up a novel scenario that indicates the promise of a next-generation medicine based on precision and personalized objectives, mostly due to the change in the paradigm regarding gene-surgery. This has certainly attracted, like never before, the attention of the biotech business and investor community. This chapter offers a brief overview of some of the factors that have contributed to a rapid entry into the biotech and pharmaceutical company's pipeline, focusing on how cell and gene therapies (CGT), collectively known as advanced therapies, have become the driving forces toward the therapeutic uses of gene editing technology. The sum of all those efforts for more than 30years has contributed to the new paradigm of considering genes as medicines. Copyright © 2017. Published by Elsevier Inc.

Of the 102 million hectares that made up the global area of biotech crops in 2006, less than 8% (7.6 million ha) were in Asia. Three biotech crops are currently planted in significant areas in four Asian countries with government regulatory approval; namely, cotton, corn (maize), and canola. However, the amount of GM crop material imported into the Asian region for processing into food and animal feed is very substantial, and almost every country imports GM food. The issues which concern Asian scientists, regulators, and the lay public resemble those of other regions - biosafety, food safety, ethics and social justice, competitiveness, and the "EU" trade question. Most Asian countries now have regulatory systems for approving the commercialization of GM crops, and for approving food safety of GM crops. In Asia, because of the varied cultures, issues concerning the use of genes derived from animals arouse much emotion for religious and diet choice reasons. Because many Asian producers and farmers are small-scale, there is also concern about technology dependency and to whom the benefits accrue. All consumers surveyed have expressed concern about potential allergenic and long-term toxic effects, neither of which is grounded on scientific facts. Because of Asia's growing demand for high volumes of quality food, it is likely that GM crops will become an increasing feature of our diet.
The objective of this work is to elucidate various essential drugs in the Brazil, Russia, India, China and South Africa (BRICS) countries. It discusses the opportunities and challenges of the existing biotech infrastructure and the production of drugs and vaccines in member states of the BRICS. This research is based on a systematic literature review between the years 2000 and 2014 of documents retrieved from the databases Embase, PubMed/Medline, Global Health, and Google Scholar, and the websites of relevant international organizations, research institutions and philanthropic organizations. Findings vary from one member state to another. These include useful comparison between the BRICS countries in terms of pharmaceuticals expenditure versus total health expenditure, local manufacturing of drugs/vaccines using technology and know-how transferred from developed countries, and biotech entrepreneurial collaborations under the umbrella of the BRICS region. This study concludes by providing recommendations to support more of inter collaborations among the BRICS countries as well as between BRICS and many developing countries to shrink drug production costs. In addition, this collaboration would also culminate in reaching out to poor countries that are not able to provide their communities and patients with cost-effective essential medicines.

The paper looks in detail at patients that were treated at one of the most discussed companies operating in the field of untried stem cell treatments, Beike Biotech of Shenzhen, China. Our data show that patients who had been treated at Beike Biotech view themselves as proactively pursuing treatment choices that are not available in their home countries. These patients typically come from a broad variety of countries: China, the United Kingdom, the United States, South Africa and Australia. Among the patients we interviewed there seemed to be both an awareness of the general risks involved in such experimental treatments and a readiness to accept those risks weighed against the possible benefits. We interpret this evidence as possibly reflecting the emergence of risk-taking patients as 'consumers' of medical options as well as the drive of patients to seek treatment options in the global arena, rather than being hindered by the ethical and regulatory constraints of their home countries. Further, we found that these patients tend to operate in more or less stable networks and groups in which they interact and cooperate closely and develop opinions and assessments of available treatment options for their ailments. These patients also perform a multiple role as patients, research subjects, and research funders because they are required to pay their way into treatment and research activities. This new social dynamics of patienthood has important implications for the ethical governance of stem cell treatments. © 2011 Blackwell Publishing Ltd.

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.
In accordance with the fast growing population, the demand for energy and the discharge of waste are also increasing day by day. So, there is two method of waste treatment that practiced by our company, centralised and de centralised. For de centralised treatment, there are some advantages like no collection, no transportation, small investment and for disadvantages, more treatment plants are needed. Waste of food materials and other bio degradable wastes generated in Factory canteens, Convents, Hospitals, Hostels, Hotels and other industrial organizations can be treated in an eco-friendly way for the production of cooking gas in very large scale. BIOTECH has completed the installation of 52 Nos. power generation projects using market /slaughter house waste. The power generated from these projects is being utilized for energy requirements of the concerned markets and to meet the in-house requirements of the projects. In recognition of our selfless services to the society through our system of waste management and the generation of Energy from waste. BIOTECH was honored by conferring on it the prestigious International Ashden Award GREEN OSCAR 2007. (Author)

We present a method that uses microcontact printing of alkanethiols on gold to generate patterned substrates presenting "islands" of extracellular matrix (ECM) surrounded by nonadhesive regions such that single cells attach and spread only on the adhesive regions. We have used this micropatterning technology to demonstrate that mammalian cells can be switched between growth and apoptosis programs in the presence of saturating concentrations of growth factors by either promoting or preventing cell spreading (Science 276:1425-1428, 1997). From the perspective of fundamental cell biology, these results suggested that the local differentials in growth and viability that are critical for the formation of complex tissue patterns may be generated by local changes in cell-ECM interactions. In the context of cell culture technologies, such as bioreactors and cellular engineering applications, the regulation of cell function by cell shape indicates that the adhesive microenvironment around cells can be carefully optimized by patterning a substrate in addition to using soluble factors (Biotech. Prog. 14:356-363, 1998). Micropatterning technology is playing a central role both in our understanding how ECM and cell shape regulate cell physiology and in facilitating the development of cellular biosensor and tissue engineering applications (Science 264:696-698, 1994; J. Neurosci. Res. 13:213-20, 1985; Biotech. Bioeng. 43:792-800, 1994).

The biotech industry is, nowadays, facing unparalleled challenges due to the enhanced demand for biotechnology-based human therapeutic products, such as monoclonal antibodies (mAbs). This has led companies to improve substantially their upstream processes, with the yield of monoclonals increasing to titers never seen before. The downstream processes have, however, been overlooked, leading to a production bottleneck. Although chromatography remains the workhorse of most purification processes, several limitations, such as low capacity, scale-related packing problems, low chemical and proteolytic stability and resins' high cost, have arisen. Aqueous two-phase extraction (ATPE) has been successfully revisited as a valuable alternative for the capture of antibodies. One of the important remaining questions for this technology to be adopted by the biotech industries is, now, how it compares to the currently established platforms in terms of costs and environmental impact. In this report, the economical and environmental sustainability of the aqueous two-phase extraction process is evaluated and compared to the currently established protein A affinity chromatography. Accordingly, the ATPE process was shown to be considerably advantageous in terms of process economics, especially when processing high titer cell culture supernatants. This alternative process is able to purify continuously the same amount of mAbs reducing the annual operating costs from 14.4 to 8.5 million (US$/kg) when cell culture supernatants with mAb titers higher than 2.5 g/L are processed.

Major changes are occurring across the science and technology (S and T) landscape in this country. Messages from Federal and State Governments in recent times could not have been clearer - in return for 'taxpayer $ into ideas' (in other words, funding for front end basic research) there is an expectation that 'ideas will be translated into $' (in other words, commercialisation will be pursued aggressively). As we in Australian S and T are constantly reminded, with part justification only, Australian researchers (especially in the life sciences) are good at generating a wealth of ideas but not much wealth from ideas. It is claimed that despite scientific excellence, many in the sector are risk averse, immobile, prone to academic snobbery, better employees than employers, not entrepreneurial etc, etc. Regardless of the veracity of any of this, the 1990s has seen a change with many more scientists interested in pursuing the progression of ideas to research to invention to intellectual property to competitive advantage to commercialisation to wealth, jobs and social development to profits and tax dollars to increased support for innovation, R and D, basic research etc. In regard to biomedical research, it has been said that '... medical biotechnology was the first business with enough glamour to persuade eminent scientists that the entrepreneurial spirit and academic respectability are not mutually exclusive. Maybe it's OK to be a science-literate businessman and to make money from science. Successful biotech companies emerge when good science meets excellent management and that combination, in an enabling environment, attracts informed investors and partners. Biotech companies may focus on a single product, a portfolio, or a technology platform and the majority are destined not to become, and have no intention of becoming, an integrated biopharmaceutical or agrochemical company. Their capacity to raise funds is influenced by 'signals' that the technology, the people

Full Text Available Microalgae are able to accumulate considerable amounts of tocopherols (up to 4 mg/g dry weight. The content of α-tocopherol to plant oils is low, whereas microalgae contain up to 97% of the tocochromanols that provides high bioactivity. The data about the content of tocopherols in eukaryotic microalgae Dunaliella tertiolecta, Nannochloropsis oculata, Isochrysis galbana, Euglena gracilis, Tetraselmis suecica, Diacronema vlkianum, as well as in the cyanobacterium Spirulina platensis are given in the paper. The largest amounts of tocopherols are synthesized by Euglena gracilis cells at mixotrophic cultivation. The level of tocopherols in microalgae depends on cultivation conditions. Two-stage biotech cultivation techniques, limiting nutrition in some biogenic elements, the introduction of exogenous carbon sources are used to increase the yield of tocopherol from microalgae. The approaches to the genetic transformation of plants leading to higher content of active vitamin E are rewieved as well.

The processes of membrane separation have been used in many different sectors of industrial activity, ranging from the chemical industry, food, pharmaceutical, medical and biotech. In this paper, a bentonite clay was added by melt intercalation in a poly(butylene adipate-co-terephthalic acid)/poly(lactic acid) blend at levels 1 and 3 wt% of clay. After that, membranes were produced by solvent evaporation technique. From the XRD results, it was verified the possible formation of exfoliated/partially exfoliated structures in the membranes. By DSC, it was observed that the addition of clay did not promote alterations in glass transition temperature and crystalline melting of the PBAT/PLA matrix. The morphology of the membranes were observed by SEM and it was verified the clay formation of porous membranes. (author)

Full Text Available This paper explores turning points in the historical relationship between gender and technoscience, most notably the gender parity of the 2009 Nobel Prizes; the public debate on the under-representation of women in science that raged world-wide but especially in the US during 2005-2006; and the construction of a public memory for a leading woman technoscientist in the mid-1990s. The paper situates these turning points in the context of historical events, most notably the Scientific Revolution of the 17th Century, WW2 and the Cold War, the women’s liberation movement of the 1970s that legally ended overt gender discrimination, and the rise of covert gender discrimination since the 1990s. The paper concludes by drawing attention to recent findings on new technoscientific environments, most notably biotech start ups, as innovative settings that offer flexibility, and hence a more viable route to gender parity.

Full Text Available This study examines the moderating role of technology uncertainty on the relationship between team contextual factors of top management support and T-shaped skills with innovation speed. For the purpose of this study, the data were collected from 227 new products from 147 biotechnology firms in Malaysia. The overall results confirmed the moderating effect of technology uncertainty on the relationship between T-shaped skills, as well as top management support with innovation speed. The results further confirmed that under the high technology uncertainty, this effect is higher in comparison to the low and medium uncertainty. This indicates that the effect of top management support and T-shaped skills on innovation speed improves when technology uncertainty increases. On the practical side, the report equips biotech firms with valuable insights to develop effective strategies.

A 36-year-old male presented with progressive exertional dyspnea over months. Physical examination showed jugular venous distension, lung crecipitations, femoral bruit and pitting pedal edema. Echocardiogram showed a dilated right ventricle with severe pulmonary hypertension and a non collapsing inferior vena cava (IVC). On right heart catheterization, IVC oxygen saturation was noted at 92% suggesting arterial mixing; a computed tomography of the abdomen showed a fistula between the right common iliac artery to the right common iliac vein at L4 level and a massive IVC; this was linked to trauma from a disectomy done 16 years ago at L4-L5 level. Endovascular sealing with a 16 × 60 mm bifurcated stent graft (S & G Biotech, Seoul, Korea) was performed which led to complete resolution of the patient's dyspnea. Iatrogenic vascular injury during lumbar disc surgery, although rare, can lead to high output cardiac failure developing over months to years.

Conflicts of interest affect the scientific communication and information: their effects on the physician's prescribing behavior have been frequently studied and clearly documented. Recently, the New England Journal of Medicine published a series of papers questioning the radical positions on this topic, asking to reconsider the most intransigent approach, so that it may be possible a productive collaboration between academic medicine and pharmaceutical industry, in the interest of the patient. The papers published in the New England Journal of Medicine confirm the difficulties experienced by the biomedical journals: the support of the industry is essential and most of the authors and referees has ties with pharmaceutical or biotech companies. The debate among the various stakeholders is vital but should be open and transparent, with the aim to restore credibility to all the parties concerned: academic medicine, pharmaceutical industry and scientific publishers.

Terpenoid flavor and fragrance compounds are of high interest to the aroma industry. Microbial production offers an alternative sustainable access to the desired terpenoids independent of natural sources. Genetically engineered microorganisms can be used to synthesize terpenoids from cheap and renewable resources. Due to its modular architecture, terpenoid biosynthesis is especially well suited for the microbial cell factory concept: a platform host engineered for a high flux toward the central C 5 prenyl diphosphate precursors enables the production of a broad range of target terpenoids just by varying the pathway modules converting the C 5 intermediates to the product of interest. In this review typical terpenoid flavor and fragrance compounds marketed or under development by biotech and aroma companies are given, and the specificities of the aroma market are discussed. The main part of this work focuses on key strategies and recent advances to engineer microbes to become efficient terpenoid producers.

Full Text Available Energy and environmental crisis facing the world force us to reconsider the effectiveness or find an alternative use of renewable natural resources, especially organic «waste» by using environmentally friendly technologies. Microbial conversion of renewable resources of biosphere to produce useful products, including biofuels, currently is an actual biotech problem. Anaerobic bacteria of Clostridiaceae family are known as butanol producers, but unfortunately, the microbiological synthesis is currently not economical one. In order to make cost-effective aceton-butanol-ethanol fermentation, solventproducing strains using available cheap raw materials, such as agricultural waste or plant biomass, are required. Opportunities and ways to obtaine economic and ecological processing of lignocellulosic wastes for biobutanol creation are described in the review .
Full Text Available Problems occurring during the immunomagnetic separation (IMS of Listeria using immunomagnetic particles Dynabeads® anti-Listeria (Dynal Biotech, Norway were specified. Characteristics of these particles were compared with anti-Listeria spp. magnetite particles (Quantum Magnetics, USA. Pure cultures of Listeria innocua, Arthrobacter spp., Bacillus subtilis, Citrobacter braakii, Escherichia coli, Enterobacter aerogenes, Enterobacter cloacae and Staphylococcus aureus were used to evaluate non-specific reactions during IMS. Gram-positive microorganisms, especially Staphylococcus aureus and Arthrobacter spp., were found to be responsible for non-specific reactions in most cases. The capacity of Dynabeads® anti-Listeria particles was determined to be about 10 % of the initial pure cultures of Listeria spp., after 10 min of incubation. Non-specific reactions during IMS of Listeria were examined on the artificially inoculated food samples in which Gram-positive bacteria showed the highest percentage of capture. Influence of washing in two buffers was also studied.

Then, on June 29, 2017......, the Administrative Council of the EPO decided to amend Rules 27 and 28 of the Implementing Regulation. According to these amendments products (animals or plants) obtained exclusively from essentially biological process are now effectively excluded from patentability. Notwithstanding that this contradicts the earlier...
Full Text Available Microbial alkaline protease has become an important industrial and commercial biotech product in the recent years and exerts major applications in food, textile, detergent, and pharmaceutical industries. By immobilization of microbes in different entrapment matrices, the enzyme produced can be more stable, pure, continuous, and can be reused which in turn modulates the enzyme production in an economical manner. There have been reports in support of calcium alginate and corn cab as excellent matrices for immobilization of Bacillus subtilis and Bacillus licheniformis, respectively. This study has been carried out using calcium alginate, κ-carrageenan, agar-agar, polyacrylamide gel, and gelatin which emphasizes not only on enzyme activity of immobilized whole cells by different entrapment matrices but also on their efficiency with respect to their reusability as first attempt. Gelatin was found to be the best matrix among all with highest enzyme activity (517 U/ml at 24 h incubation point and also showed efficiency when reused.

CNS has historically been a formidable therapeutic area in which to innovate owing to biological (e.g., complex neurobiology, difficulty reaching the target), as well as clinical (e.g., subjective clinical endpoints, high placebo response, lack of biomarkers) challenges. In the current market where many of the larger diseases are dominated by a generic standard of care, commercial challenges now make the triple threat of scientific-clinical-commercial risk too much for many players to tackle. However, opportunities do exist for smaller biotech companies to concentrate on narrowly focused patient populations associated with high unmet need for which risk can be tightly defined. In CNS, there are two major areas to balance the risk/reward profile and create commercially viable opportunities: To realize value, all companies (start-ups and big players) must define, measure and quantify clear and meaningful value to all stakeholders: physicians, patients, caregivers and payers. © 2013.

In June 2013, the U.S. Supreme Court rendered a controversial ruling that naturally occurring DNA segments are "products of nature" and therefore not patentable subject matter. At this intersection between science and law, in litigation of crucial importance to patients, science, and multibillion-dollar biotech enterprises, the appellate judges sidestepped genetics and engaged in a war of metaphors from diamonds to chocolate chip cookies. This case is not an outlier. Apprehensive judges and juries in both Canada and the United States find many convenient excuses to avoid coming to grips with the underlying science in patent cases. But this is simply not acceptable. Legal rulings must be, and must seem to be, well grounded, as a matter of both law and science. The legitimacy of court decisions in the eyes of the stakeholders and the broader public depends on it. Copyright © 2015 Cold Spring Harbor Laboratory Press; all rights reserved.

for instance as food additives, nutraceutical, for paper and energy production. Pectin is a cell wall glycan that crucial for every plant growing on land. Pectin is said to be one of the most complex glycans on earth and it is hypothesized that at least 67 enzymatic reactions are involved in its biosynthesis...... for their ability to detect PPI inside the Golgi lumen. The first method tested was the commercially available splitubiquitin system from Dualsystems Biotech AG. This was applied to test binary interactions between proteins involved in HG and Rhamnogalacturonan I (RG-I) biosynthesis (see Manuscript II......

The discovery of a novel enzyme from a microbial source takes anywhere between months to years, and therefore, there has been an immense interest in modifying the existing microbial enzymes to suit the present day needs of the industry. The redesigning of industrially useful enzymes for improving their performance has become a challenge because bioinformatics databases have been revealing new facts on a day-to-day basis. Modification of the existing enzymes has become a trend for fine tuning of biocatalysts in the biotech industry. Hydrolases are employed in pharmaceutical, biofuel, detergent, food and feed industries that significantly contribute to the global annual revenue, and therefore, the emphasis has been on engineering them. Although a large data is accumulating on making alterations in microbial enzymes, there is a lack of definite information on redesigning industrial enzymes. This review focuses on the recent developments in improving the characteristics of various biotechnologically important enzymes. Copyright © 2014 Elsevier Ltd. All rights reserved.

"Genetically modified" (GM) or "biotech" crops have been the most rapidly adopted agricultural technology in recent years. The development of a GM crop encompasses trait identification, gene isolation, plant cell transformation, plant regeneration, efficacy evaluation, commercial event identification, safety evaluation, and finally commercial authorization. This is a lengthy, complex, and resource-intensive process. Crops produced through biotechnology are the most highly studied food or food component consumed. Before commercialization, these products are shown to be as safe as conventional crops with respect to feed, food, and the environment. This paper describes this global process and the various analytical tests that must accompany the product during the course of development, throughout its market life, and beyond.

This year is a special year for plant biotechnology. It was 30 years ago, on January 18 1983, one of the most important dates in the history of plant biotechnology, that three independent groups described Agrobacterium tumefaciens-mediated genetic transformation at the Miami Winter Symposium, leading to the production of normal, fertile transgenic plants (Bevan et al. in Nature 304:184-187, 1983; Fraley et al. in Proc Natl Acad Sci USA 80:4803-4807, 1983; Herrera-Estrella et al. in EMBO J 2:987-995, 1983; Vasil in Plant Cell Rep 27:1432-1440, 2008). Since then, plant biotechnology has rapidly advanced into a useful and valuable tool and has made a significant impact on crop production, development of a biotech industry and the bio-based economy worldwide.
Aesthetic creation involves a close collaboration between discovery, invention and cultural exhibition, as well as between learning and producing value. It is typified by the patterns of creative behavior in highly innovative communities like Silicon Valley (for IT) or Boston (for biotech) where cultures of learning, experimentation, and production or commercialization coexist, and where a high degree of interdisciplinary collaboration occurs. In this lecture, David Edwards will highlight the growing movement of aesthetic creation in the arts, sciences and engineering as a path for sustaining and improving the human condition in the longest term. He will highlight aesthetic creation in the light of the culture lab model of Le Laboratoire (Paris, Cambridge) and the new World Frontiers Forum with examples of learning, pubic experimentation and value creation particularly related to the future of sensory experience.
In the 1980s, capillary electrophoresis (CE) joined high-performance liquid chromatography (HPLC) as the most powerful separation technique available to analytical chemists and biochemists. Published research using CE grew from 48 papers in the year of commercial introduction (1988) to 1200 in 1997. While only a dozen major pharmaceutical and biotech companies have reduced CE to routine practice, the applications market is showing real or potential growth in key areas, particularly in the DNA marketplace for genomic mapping and forensic identification. For drug development involving small molecules (including chiral separations), one CE instrument can replace 10 liquid chromatographs in terms of speed of analysis. CE also uses aqueous rather than organic solvents and is thus environmentally friendlier than HPLC. The second edition of Practical Capillary Electrophoresis has been extensively reorganized and rewritten to reflect modern usage in the field, with an emphasis on commercially available apparatus and ...

In February this year, about 100 delegates gathered for three days in Vienna (Austria) for the Next Generation Vaccines conference. The meeting held in the Vienna Hilton Hotel from 23rd-25th February 2011 had a strong focus on biotech and industry. The conference organizer Jacob Fleming managed to put together a versatile program ranging from the future generation of vaccines to manufacturing, vaccine distribution and delivery, to regulatory and public health issues. Carefully selected top industry experts presented first-hand experience and shared solutions for overcoming the latest challenges in the field of vaccinology. The program also included several case study presentations on novel vaccine candidates in different stages of development. An interactive pre-conference workshop as well as interactive panel discussions during the meeting allowed all delegates to gain new knowledge and become involved in lively discussions on timely, interesting and sometimes controversial topics related to vaccines.

Work–life balance has become an important topic for both mainstream and critical scholars. We will provide here an empirical analysis of work–life balance from the theoretical perspective of Gilbert Simondon. In such a perspective, individuals’ efforts to balance work with life should be viewed...... as part of an individuation process, neither reducible to the sphere of work nor of life. Qualitative data gathered at a global biotech firm has demonstrated how problems related to work–life balance, such as working while ill and working from home, illustrate ways employees become individuated....... The article ends by discussing the contribution and relevance of Simondon’s thinking to current theories of work–life balance in relation to research methodology and ethics....

MicroRNAs (miRNAs) are small, noncoding RNAs of about 22 nucleotides in length and have proven to be useful targets for genetic modifications for desirable phenotype in the biotech industry. The use of constitutively expressed "miRNA sponge" vectors in which multiple, tandem miRNA binding sites containing transcripts are transcriptionally regulated by a constitutive promoter for down regulating the levels of endogenous microRNAs in Chinese hamster ovary (CHO) cells has shown to be more advantageous than using synthetic antisense oligonucleotides. The application of miRNA sponges in biotechnological processes, however, could be more effective, if expression of miRNA sponges could be tuned. In this chapter, we present a method for the generation of stable CHO cell lines expressing a TET-ON-SanDI-miRNA-sponge that is in theory expressed only in the presence of an inducer.
Genomics has brought biology, medicine, agriculture, psychology, anthropology, and even philosophy to a new threshold. In this new context, the question about "what is human in humans" may end up being answered by geneticists, specialists of technoscience, and owners of biotech companies. The author defends, in this article, the idea that humanity is at risk in our age of genetic engineering, biotechnologies, and market-geared genetic research; he also argues that the values at the very core of our postgenomic era bring to its peak the science-based ideology that has developed since the time of Galileo, Newton, Descartes, and Harvey; finally, it shows that the bioindustry has invented a new genomythology that goes against the scientific evidence produced by the research in human sciences in which life is interpreted as a language.
As pharmaceutically active ingredients continue to become more ′′potent′′ the effective controlled delivery of doses have become intriguing. As a result, polymers now often constitute the major portion of many pharmaceutical dosage forms and as such can have profound impact on the reproducibility of drug release and overall performance of the dosage forms.The technical complexities associated with drug development have increased in controlled delivery due to challenges such as complex drug actives, and in cases of biotech products, stabilization of the active ingredient. The multidisciplinary understanding of polymers is thus required including technical, safety, quality, and regulatory aspects, which, prior to this effort, has not been available in a single resource. It also proposes new and innovative ways for regulatory review of polymers, which, if adopted,

The pharmaceutical industry continues to face fundamental challenges because of issues with research and development (R&D) productivity and rising customer expectations. To lower R&D costs, move beyond me-too therapies, and create more transformative portfolios, pharmaceutical companies are actively capitalizing on external innovation through precompetitive collaboration with academia, cultivation of biotech start-ups, and proactive licensing and acquisitions. Here, we review the varying innovation strategies used by pharmaceutical companies, compare and contrast these models, and identify the trends in external innovation. We also discuss factors that influence these external innovation models and propose a preliminary set of metrics that could be used as leading indicators of success. Copyright © 2014 Elsevier Ltd.

This paper explores the relevance of the concept of self in the process of independent technological innovation. In‐depth interviews were conducted with technological innovators from start‐up firms in IT, biotech and advanced services concerning the subjective and social forms of engagement...... in the innovation process. Emerging factors in the interview data revealed aspects pertaining to the innovator’s reflexive self‐conception, innovator ego‐involvement in the venture, forms of commitment and control, personal and social stakes, and various self‐oriented cognitive strategies. It is argued...... that the self‐concept allows the innovator to come into view as a social and subjective being who is involved in reflexive activities such as dynamic role‐taking, “is” vs “ought” reflections and social negotiations....
Full Text Available Abstract Background Concerns have recently been raised about the negative effects of patents on innovation. In this study, the effects of patents on innovations in the Korean biotech SMEs (small and medium-sized entrepreneurs were examined using survey data and statistical analysis. Results The survey results of this study provided some evidence that restricted access problems have occurred even though their frequency was not high. Statistical analysis revealed that difficulties in accessing patented research tools were not negatively correlated with the level of innovation performance and attitudes toward the patent system. Conclusion On the basis of the results of this investigation in combination with those of previous studies, we concluded that although restricted access problems have occurred, this has not yet deterred innovation in Korea. However, potential problems do exist, and the effects of restricted access should be constantly scrutinized.

Full Text Available The financial sector is living a profound crisis in order to keep pace with the continuous technological breakthroughs that come out daily, while other sectors seem to be historically more growth-by-innovation-based (e.g., the pharma/biotech sector. This work focuses on an interdisciplinary approach to innovation, and on insights that the banking sector can draw from the pharmaceutical one. Hence, a unique dataset has been built, and it collects information on the most relevant players for both the fields. Different indicators have been created as well in order to empirically test whether the financial industry is actually less innovative with respect to the pharmaceutical one, and to understand the best growing strategy for the banking industry. The results confirm that there is an innovation gap between the two industries, as well as identify the corporate venture capital as the best mean to drive business growth through innovation.

I am trying to make money in the biotech industry from complexity science. And I am doing it with inspiration that I picked up on the edge of Appalachia spending time with June Holley and ACEnet when I was a Wall Street Journal reporter. I took some of those ideas to Pittsburgh, in biotechnology, in a completely private setting with an economic development focus, but also with a mission t o return profit to private capital. And we are doing that. I submit as a hypothesis, something we are figuring out in the post- industrial era, that business evolves. It is not the definition of business, but business critically involves the design of systems in which uncertainty is treated as a certainty. That is what I have seen and what I have tried to put into practice.

The biotechnology industry is concerned about a coalition of mainstream religious leaders, working with Jeremy Rifkin of the Foundation of Economic Trends, who oppose the patenting of human and animal life forms, body parts, and genes. The coalition called a press conference on May 18 to ask the government to prohibit the current patenting practices for genetic engineering. The biotechnology industry argues that patents indicate that a company's research tool has significant value, and encourages capitalists to invest their dollars in the development of new treatments for diseases. They also argue that the 29 biotech drugs that are on the market have been developed as a result of patents on genes. Although most business leaders are united in opposing restrictions, many scientists are divided, citing both religious and scientific reasons.

Within the broader context of several related biotech developments, including the proliferation of GM food in American grocery stories, the recent decision by Whole Foods Market, Inc. to require the labeling of all genetically modified (GM) organism products sold in its stores by 2018, and the development of GM animals for consumption, this essay asks whether the United States is inching towards a policy of mandatory GM food labeling. The analysis highlights aspects of the biotechnology policy debate in the United States and European Union, and traces public opinion as well as grassroots and legislative efforts aimed at GM food labeling. Findings show that activities at the federal level do not suggest any major regulatory changes regarding labeling in the near future; however, a growing number of individual states are considering GM food labeling legislation and political momentum in favor of labeling has picked up in recent years. Voluntary labeling by food companies may also become increasingly common.

Leptospirosis is an emerging infectious disease. The differential diagnosis of leptospirosis is difficult due to the varied and often "flu like" symptoms which may result in a missed or delayed diagnosis. Leptospira is the aetiological agent of leptospirosis, a bacterial zoonosis with worldwide distribution. There are over 230 known serovars in the genus Leptospira. The true prevalence of leptospirosis in Malaysia is unknown or underestimated. Our goal was to determine the prevalence for Leptospira infection in rodents in a selected area in Beguk Dam Labis, Segamat, Johor. A study was carried out on 69 serum samples of trapped wild rodents. DNA was extracted from the sera using Leptospira PCR kit (Shanghai ZJ Bio-Tech Co., Ltd). Of 69 rodent serum samples tested by PCR, 9 (13%) showed positive results. In this study we found that (13%) of wild rodents caught in Beguk Dam Labis were infected by Leptospira.
The European Court of Justice (ECJ) has recently issued a ruling in Case C-364/13 International Stem Cell Corporation v. Comptroller General of Patents Designs and Tademarks (Case) that aims at harmonising the patenting practices regarding interpretation of Article 6.2.c of Directive 98/44/EC (Biotech Patent Directive) in respect of patentability of human parthenogenic stem cells (hpSCs). The Case alters the patenting regime for human embryonic stem cell (hESC) applications, by stating that moral restrictions against hESC-patents are only applicable to such cells derived from embryos that had the potential to develop into a human being. Consequently, hpSC-based inventions may be patentable in Europe. This Case represents a leap forward to striking a balance between protecting human dignity and integrity whilst granting patent incentives for biomedical research.

Full Text Available This paper examines the ethics of big data in agriculture, focusing on the power asymmetry between farmers and large agribusinesses like Monsanto. Following the recent purchase of Climate Corp., Monsanto is currently the most prominent biotech agribusiness to buy into big data. With wireless sensors on tractors monitoring or dictating every decision a farmer makes, Monsanto can now aggregate large quantities of previously proprietary farming data, enabling a privileged position with unique insights on a field-by-field basis into a third or more of the US farmland. This power asymmetry may be rebalanced through open-sourced data, and publicly-funded data analytic tools which rival Climate Corp. in complexity and innovation for use in the public domain.

This review introduces patents and trade secrets, the two mechanisms that U.S. law provides inventors to protect their inventions. These mechanisms are mutually exclusive: One demands disclosure and the other calls for concealment. Many biotechnology innovators opt for patents, which grant legal, time-limited monopolies to eligible inventions.To obtain a patent in the United States, an invention must be useful to the public and made or altered by the hand of man. It must then clear the hurdles of novelty and nonobviousness. If an invention can do that, obtaining a patent becomes a matter of form: Who qualifies as an inventor? Does the application demonstrate possession, stake a clear claim to the protection sought, and enable "ordinary" colleagues to replicate it? Has the inventor purposely withheld anything? This review addresses each of these hurdles as they apply to biotech inventions. Copyright © 2015 Cold Spring Harbor Laboratory Press; all rights reserved.
The oncolytic viruses now hold a promise of new therapeutic strategy for cancer. Its concept has inspired a wave of commercial research and development activities for the products of this category in China since 1998. The first commercialized oncolytic virus product in the world, Oncorine (H101), developed by Shanghai Sunway Biotech Co., Ltd since 1999, was approved by Chinese SFDA in November, 2005 for nasopharyngeal carcinoma in combination with chemotherapy after the phase III clinical trial, and finally acquired GMP certificate in August, 2006. This review introduces how Oncorine was successfully developed in China, and how the Chinese market responded after it was launched into the market in 2006.

This article provides new insights into the different strategy paths or business models currently being implemented by Canadian biopharma companies. Through a case-study methodology, seven biopharma companies pertaining to three business models were analyzed, leading to a broad set of results emerging from the following areas: activity, business model and strategy; management and human resources; and R&D, technology and innovation strategy. The three business models represented were: model 1 (conventional biotech oriented to new drug development, radical innovation and search for discoveries); model 2 (development of a technology platform, usually in proteomics and bioinformatics); and model 3 (incremental innovation, with shorter and less risky development timelines).

After the biotech medicine era, regenerative medicine is expected to be an advanced medicine that is capable of curing patients with difficult-to-treat diseases and physically impaired function. Our original scaffold-free cell sheet-based tissue engineering technology enables transplanted cells to be engrafted for a long time, while fully maintaining their viability. This technology has already been applied to various diseases in the clinical setting, including the cornea, esophagus, heart, periodontal ligament, and cartilage using autologous cells. Transplanted cell sheets not only replace the injured tissue and compensate for impaired function, but also deliver growth factors and cytokines in a spatiotemporal manner over a prolonged period, which leads to promotion of tissue repair. Moreover, the integration of stem cell biology and cell sheet technology with sufficient vascularization opens possibilities for fabrication of human three-dimensional vascularized dense and intact tissue grafts for regenerative medicine to parenchymal organs.

The literatures on innovation and organizational learning have identified search in prior science and technology as critical inputs to industrial R&D. Efforts to distinguish the contributions - separately and combined - of these two search orientations are scarce, and quantitative estimates offer...... contradictory results. The contributions to R&D from science are particularly elusive. To achieve some transparency on these issues we study R&D in biotech drug discovery, where the role of science is pervasive and structured into a recurrent sequence of inventions required to build a drug candidate....... The patents filed on these inventions offer, through their citations to prior art, a fine-grained view of the role of science along the R&D cycle. Applying a unique text-mining algorithm we categorize a set of 1,058 patens from Scandinavian drug discovery firms into six types of drug-related inventions. Tests...

This internship program set out to further define and enhance the talent pipeline from the University and local Community Colleges to startup culture in East Bay Area, provide undergraduate STEM students with opportunities outside academia, and provide startup companies with much needed talent. Over the 4 year period of performance, the Bio-Manufacturing to Market internship program sponsored 75 undergraduate STEM students who were able to spend anywhere from one to six semesters working with local Bay Area startup companies and DOE sponsored facilities/programs in the biotech, bio-manufacturing, and biomedical device fields.
Biotech patents are facing increasingly stern challenges. The patent statue holds that a multi-step method patent is not directly infringed unless all steps are carried out and attributed to a single entity. When separate steps are performed jointly by two or more parties, those parties are liable for divided infringement if there exists a direct infringement. Possibilities thus exist for unauthorized but non-infringing joint performance, i.e. enforcing a method patent will be difficult if joint performance stands as a valid defense against direct infringement. Areas covered: This analysis covers issues on patent infringement, specifically on divided infringement of diagnostic and method patents. Expert opinion: A retrospective analysis indicates that a large number of cancer diagnostic patents issued during 2005-2014 are potentially vulnerable to read on unauthorized use in the manner of joint performance. Inventors should draft patent claims appropriately to reduce the risk to assert their patents in this regard.

The pharmaceutical and biotech industries face continued pressure to reduce development costs and accelerate process development. This challenge occurs alongside the need for increased upstream experimentation to support quality by design initiatives and the pursuit of predictive models from systems biology. A small scale system enabling multiple reactions in parallel (n ≥ 20), with automated sampling and integrated to purification, would provide significant improvement (four to fivefold) to development timelines. State of the art attempts to pursue high throughput process development include shake flasks, microfluidic reactors, microtiter plates and small-scale stirred reactors. The limitations of these systems are compared to desired criteria to mimic large scale commercial processes. The comparison shows that significant technological improvement is still required to provide automated solutions that can speed upstream process development.

Since the 1970s, biotechnology has been a key innovator in drug development. An analysis of FDA-approved therapeutics demonstrates pharmaceutical companies outpace biotechs in terms of new approvals but biotechnology companies are now responsible for earlier-stage activities (patents, INDs or clinical development). The number of biotechnology organizations that contributed to an FDA approval began declining in the 2000s and is at a level not seen since the 1980s. Whereas early biotechnology companies had a decade from first approval until acquisition, the average acquisition of a biotechnology company now occurs months before their first FDA approval. The number of hybrid organizations that arise when pharmaceutical companies acquire biotechnology is likewise declining, raising questions about the sustainability of biotechnology.

The first protein crystallography group in Switzerland was installed at the Biozentrum of the University of Basel approximately 40 years ago. Since then protein crystallography has grown and matured remarkably and is now established in the molecular biology, biochemistry or biological medicine departments of most major Swiss Universities as well as in the pharmaceutical industry and in biotech startup companies. Swiss X-ray biocrystallography groups have made remarkable contributions from the beginning and have brought Switzerland to the forefront in biostructural research during the last 5 to 10 years. Switzerland has now a leading position in the areas of supramolecular complexes, membrane proteins and structure-based drug design in pharmaceutical and biotech industries. Protein crystallography on the outer membrane protein ompF as well as the development of the lipidic cubic phase crystallization methodology has been pioneered at the Biozentrum. The latter found its somewhat late recognition through the recent explosion in structure determinations of the seven transmembrane helix G-coupled receptors. Highlights from Swiss structural biology groups in the field of supramolecular complexes include the structures of ribosomal particles, of the nucleosome and the pilus assembly complex of uropathogenic E. coli. On the membrane protein side advances in the field of ABC transporters and ion channels are world-recognized achievements of Swiss structural biology. Dedicated laboratories at many academic and industrial institutions, their current research programs, the availability of excellent infrastructure and the continuing efforts to build new facilities such as the SwissFEL indicate an even brighter future for structural biology in Switzerland.
Full Text Available Filtration steps are ubiquitous in biotech processes due to the simplicity of operation, ease of scalability and the myriad of operations that they can be used for. Microfiltration, depth filtration, ultrafiltration and diafiltration are some of the most commonly used biotech unit operations. For clean feed streams, when fouling is minimal, scaling of these unit operations is performed linearly based on the filter area per unit volume of feed stream. However, for cases when considerable fouling occurs, such as the case of harvesting a therapeutic product expressed in Pichia pastoris, linear scaling may not be possible and current industrial practices involve use of 20–30% excess filter area over and above the calculated filter area to account for the uncertainty in scaling. In view of the fact that filters used for harvest are likely to have a very limited lifetime, this oversizing of the filters can add considerable cost of goods for the manufacturer. Modeling offers a way out of this conundrum. In this paper, we examine feasibility of using the various proposed models for filtration of a therapeutic product expressed in Pichia pastoris at constant pressure. It is observed that none of the individual models yield a satisfactory fit of the data, thus indicating that more than one fouling mechanism is at work. Filters with smaller pores were found to undergo fouling via complete pore blocking followed by cake filtration. On the other hand, filters with larger pores were found to undergo fouling via intermediate pore blocking followed by cake filtration. The proposed approach can be used for more accurate sizing of microfilters and depth filters.
Dr. Phil Segre, a physicist by training, is a recent addition to the Biotech group, SD46, having joined NASA in August of 2000. Over the past two years he has been developing a laboratory for the study of macromolecular and protein crystal growth. The main apparatus for this work is a Dynamic Light Scattering apparatus, DLS, which is capable of making highly precise measurements of size distributions of both protein solutions and protein crystals. With Drs. Chernov and Thomas (USRA), he has begun a collaboration studying the affects of protein impurities on protein crystal growth and subsequent crystal quality. One of the hypotheses behind the differences between Earth and space grown protein crystals is that the absorption of harmful impurities is reduced in space due to the absence of convective flows. Using DLS measurements we are examining crystal growth with varying amounts of impurities and testing whether there is a strong physical basis behind this hypothesis. With Dr. Joe Ng of UAH he has been collaborating on a project to examine the folding/unfolding dynamics of large RNA complexes. A detailed understanding of this process is necessary for the handling of RNA in biotech applications, and the DLS instrument gives details and results beyond that of other instruments. With Prof. Jim McClymer of the University of Maine (summer faculty visitor to NASA in 2001, 2002), we have been studying the crystallization process in model colloidal suspensions whose behavior in some cases can mimic that of much smaller protein solutions. An understanding of the self-assembly of colloids is the first step in the process of engineering novel materials for photonic and light switching applications. Finally, he has begun an investigation into the physics of particle sedimentation. In addition to the DLS instrument he also has an instrument (called PIV) that can measure flow fields of fluids. The applications are to the dynamics of protein crystal motions both on earth and in

Brucellosis is a worldwide zoonotic disease and still constitutes a major public health problem. In this study, we aimed to identify biovars of Brucella strains isolated from clinical specimens taken from brucellosis patients from the Eastern Anatolia region as well determine the susceptibility of these isolates to tigecycline and azithromycin, drugs that may serve as alternatives to the conventional drugs used in the therapy. Seventy-five Brucella spp. isolates were included in the study. All strains were identified by both conventional and molecular methods. Brucella Multiplex PCR kit (FC-Biotech, Code: 0301, Turkey) and B. melitensis biovar typing PCR kit (FC-Biotech, Code: 0302, Turkey) were used for molecular typing. Antimicrobial susceptibilities of all strains were determined by E-tests. By conventional biotyping, 73 strains were identified as B. melitensis biovar 3 and two strains as B. abortus biovar 3. Molecular typing results were compatible with conventional methods. The MIC50 and MIC90 values of doxycycline were 0.047 and 0.094; tigecycline 0.094 and 0.125; trimethoprim/sulfamethoxazole 0.064 and 0.19; ciprofloxacin 0.19 for both; streptomycin 0.75 and 1; rifampin 1 and 2 and azithromycin 4 and 8. According to the MIC values, doxycycline was found to be the most effective antibiotic, followed by tigecycline, trimethoprim-sulfamethoxazole and ciprofloxacin. Currently recommended antibiotics for the treatment of brucellosis such as doxycycline, rifampin, streptomycin, trimethoprim-sulfamethoxazole and ciprofloxacin were found to be still effective. While our results showed that tigecycline can be used an alternative agent in the treatment of brucellosis, azithromycin has not been confirmed as an appropriate agent for the treatment.

Biotechnology is providing us with a wide range of options for how we can use agricultural and commercial forestry lands. The cultivation of genetically modified (GM) crops on millions of hectares of lands and their injection into our food chain is a huge global genetic experiment involving all living beings. Considering the fast pace of new advances in production of genetically modified crops, consumers, farmers and policymakers worldwide are challenged to reach a consensus on a clear vision for the future of world food supply. The current food biotechnology debate illustrates the serious conflict between two groups: 1) Agri-biotech investors and their affiliated scientists who consider agricultural biotechnology as a solution to food shortage, the scarcity of environmental resources and weeds and pests infestations; and 2) independent scientists, environmentalists, farmers and consumers who warn that genetically modified food introduces new risks to food security, the environment and human health such as loss of biodiversity; the emergence of superweeds and superpests; the increase of antibiotic resistance, food allergies and other unintended effects. This article reviews major viewpoints which are currently debated in the food biotechnology sector in the world. It also lays the ground-work for deep debate on benefits and risks of Biotech-crops for human health, ecosystems and biodiversity. In this context, although some regulations exist, there is a need for continuous vigilance for all countries involved in producing genetically engineered food to follow the international scientific bio-safety testing guidelines containing reliable pre-release experiments and post-release track of transgenic plants to protect public health and avoid future environmental harm.

Full Text Available This paper examines the governance of property rights on genetically modified (GM soybean seeds. Specifically, the article undertakes a comparative analysis on the collection of royalties in GM soybean seeds in the U.S. and Brazil. For each country, the authors describe the regulatory framework governing the protection of biotechnology innovations in agriculture and investigate the mechanisms of royalty collection in GM soybean seeds. The paper also offers econometric evidence linking the capture of value on biotech innovations and the protection mechanisms deployed by biotech firms. The results suggest that, subject to the institutional environment, firms may choose to transact a GM attribute separated from the seed, building specialized governance structures framed around the genetic attribute and not around the seed as a whole.Este artigo examina a governança de direitos de propriedade em sementes transgênicas de soja. Especificamente, o estudo empreende uma análise comparativa sobre a cobrança de royalties em sementes transgênicas de soja nos EUA e no Brasil. Para cada país, os autores descrevem a estrutura regulatória que rege a proteção de inovações biotecnológicas na agricultura e investigam os mecanismos de cobrança de royalties em sementes transgênicas de soja. O artigo também examina evidências econométricas que relacionam a captura de valor sobre inovações biotecnológicas e os mecanismos de proteção utilizados por firmas de biotecnologia. Os resultados sugerem que, com base no ambiente institucional, uma firma pode optar por transacionar um atributo transgênico separado da semente, estabelecendo estruturas especializadas de governança que se emolduram em torno do atributo e não da semente em si.

Farmers in 25 countries on six continents are using plant biotechnology to solve difficult crop production challenges and conserve the environment. In fact, 13.3 million farmers, which include 90 percent of the farming in developing countries, choose to plant biotech crops. Over the past decade, farmers increased area planted in genetically modified (GM) crops by more than 10 percent each year, thus increasing their farm income by more than 44 billion US dollars (1996-2007), and achieved economic, environmental and social benefits in crops such as soybeans, canola, corn and cotton. To date, total acres of biotech crops harvested exceed more than 2 billion with a proven 13-year history of safe use. Over the next decade, expanded adoption combined with current research on 57 crops in 63 countries will broaden the advantages of genetically modified foods for growers, consumers and the environment. Genetically modified (GM) crops with the ability to produce toxins lethal to specific insect pests are covering a larger percentage of the agricultural landscape every year. The United States department of Agriculture (USDA) estimated that 63 percent of corn and 65 percent of cotton contained these specific genetic traits in 2009. The toxins could protect billions of dollars of loss from insect damage for crops valued at greater than 165 billion US dollars in 2008. The stable and efficient production of these crops has taken on even more importance in recent years with their use, not only as a food source, but now also a source of fuel. It is in the best interest of the United States Environmental Protection Agency (USEPA) to ensure the continued efficacy of toxin producing GM crops as their use reduces pesticides harmful to humans and animals. However, population genetics models have indicated the risk of insect pests developing resistance to these toxins if a high percentage of acreage is grown in these crops. The USEPA is developing methods to monitor the agricultural

In the fast-paced field of biotechnology where innovation has such far-reaching impacts on human health and the environment, dealing with the implications of possible illicit activities, accidents or unintended research consequences with potential detrimental societal impacts tends to remain in the background. While controls may be inevitable for the biotech industry, workshop attendees agreed that the way in which controls are implemented will play a major role in the agility and innovation of the biotechnology industry. There is little desire to slow down the pace of the gains while dealing with the security issues that arise. As was seen from the brief examinations of the Nuclear, Chemical, and Information Technology sectors explored in this workshop, establishing a regulatory regime needs to be a partnership between the public, corporate interests, scientists, and the government. Regulation is often written to combat perceived risk rather than actual risk—the public’s perceptions (occasionally even fictional portrayals) can spur regulatory efforts. This leads to the need for a thorough and continuing assessment of the risks posed by modern biotechnology. Inadequate or minimal risk assessment might expedite development in the short term but has potential negative long-term security and economic consequences. Industry and the technical community also often have a large role in setting regulatory policy, especially when well-crafted incentives are incorporated into the regulations. Such incentives might actually lead to enhanced innovation while poorly designed incentives can actually reduce safety and security. Any regulations should be as agile and flexible as the technology they regulate and when applied to biotechnologies they will need a new framework for thinking and implementing. The new framework should consider biotechnology as a technology and not simply a science since it is an extremely complex and adaptive system. This suggests the need to invest

High pressure has emerged as an important tool to tackle several problems in medicine and biotechnology. Misfolded proteins, aggregates and amyloids have been studied, which point toward the understanding of the protein misfolding diseases. High hydrostatic pressure (HHP) has also been used to dissociate non-amyloid aggregates and inclusion bodies. The diverse range of diseases that result from protein misfolding has made this theme an important research focus for pharmaceutical and biotech companies. The use of high pressure promises to contribute to identifying the mechanisms behind these defects and creating therapies against these diseases. High pressure has also been used to study viruses and other infectious agents for the purpose of sterilization and in the development of vaccines. Using pressure, we have detected the presence of a ribonucleoprotein intermediate, where the coat protein is partially unfolded but bound to RNA. These intermediates are potential targets for antiviral compounds. The ability of pressure to inactivate viruses, prions and bacteria has been evaluated with a view toward the applications of vaccine development and virus sterilization. Recent studies demonstrate that pressure causes virus inactivation while preserving the immunogenic properties. There is increasing evidence that a high-pressure cycle traps a virus in the 'fusion intermediate state', not infectious but highly immunogenic.
Full Text Available The present study compared the value of using a virtual learning simulation compared to traditional lessons on the topic of evolution, and investigated if the virtual learning simulation could serve as a catalyst for STEM academic and career development, based on social cognitive career theory. The investigation was conducted using a crossover repeated measures design based on a sample of 128 high school biology/biotech students. The results showed that the virtual learning simulation increased knowledge of evolution significantly, compared to the traditional lesson. No significant differences between the simulation and lesson were found in their ability to increase the non-cognitive measures. Both interventions increased self-efficacy significantly, and none of them had a significant effect on motivation. In addition, the results showed that the simulation increased interest in biology related tasks, but not outcome expectations. The findings suggest that virtual learning simulations are at least as efficient in enhancing learning and self-efficacy as traditional lessons, and high schools can thus use them as supplementary educational methods. In addition, the findings indicate that virtual learning simulations may be a useful tool in enhancing student’s interest in and goals toward STEM related careers.

Vanillin is one of the world's most important flavor compounds, with a global market of 180 million dollars. Natural vanillin is derived from the cured seed pods of the vanilla orchid (Vanilla planifolia), but most of the world's vanillin is synthesized from petrochemicals or wood pulp lignins. We have established a true de novo biosynthetic pathway for vanillin production from glucose in Schizosaccharomyces pombe, also known as fission yeast or African beer yeast, as well as in baker's yeast, Saccharomyces cerevisiae. Productivities were 65 and 45 mg/liter, after introduction of three and four heterologous genes, respectively. The engineered pathways involve incorporation of 3-dehydroshikimate dehydratase from the dung mold Podospora pauciseta, an aromatic carboxylic acid reductase (ACAR) from a bacterium of the Nocardia genus, and an O-methyltransferase from Homo sapiens. In S. cerevisiae, the ACAR enzyme required activation by phosphopantetheinylation, and this was achieved by coexpression of a Corynebacterium glutamicum phosphopantetheinyl transferase. Prevention of reduction of vanillin to vanillyl alcohol was achieved by knockout of the host alcohol dehydrogenase ADH6. In S. pombe, the biosynthesis was further improved by introduction of an Arabidopsis thaliana family 1 UDP-glycosyltransferase, converting vanillin into vanillin beta-D-glucoside, which is not toxic to the yeast cells and thus may be accumulated in larger amounts. These de novo pathways represent the first examples of one-cell microbial generation of these valuable compounds from glucose. S. pombe yeast has not previously been metabolically engineered to produce any valuable, industrially scalable, white biotech commodity.

The propagation of perturbations in protein concentration through a protein interaction network (PIN) can shed light on network dynamics and function. In order to facilitate this type of study, PerturbationAnalyzer, which is an open source plugin for Cytoscape, has been developed. PerturbationAnalyzer can be used in manual mode for simulating user-defined perturbations, as well as in batch mode for evaluating network robustness and identifying significant proteins that cause large propagation effects in the PINs when their concentrations are perturbed. Results from PerturbationAnalyzer can be represented in an intuitive and customizable way and can also be exported for further exploration. PerturbationAnalyzer has great potential in mining the design principles of protein networks, and may be a useful tool for identifying drug targets. PerturbationAnalyzer can be accessed from the Cytoscape web site http://www.cytoscape.org/plugins/index.php or http://biotech.bmi.ac.cn/PerturbationAnalyzer. Supplementary data are available at Bioinformatics online.
Major disinfection by-products (DBPs) from the chlorination process of drinking water include trihalomethanes (THMs) and haloacetic acides (HAA5). THMs mainly consist of chloroform, and other harsh chemicals. Prolonged consumptions of drinking water containing high levels of THMs has been linked with diseases of the liver, kidneys, bladder, or central nervous system and may increase likelihood of cancer. A risk also exists for THMs exposure via inhalation while showering, bathing or washing clothes and dishes. Due to these risks, the U.S. EPA regulate THMs content in drinking water. This research investigates biological degradation of THM using chloroform as a model compound. The study aims to decrease possible risks of THMs through filtration. Throughout this year’s presentations, there is a common theme of health and safety concerns. UC researchers are working hard to clean water ways of naturally occurring contaminates as well as man-made toxins found in our waterways. The significance of these presentations translates into the promise of safer environments, and more importantly saved lives, as UC’s faculty continues to produce real-world solutions to problems threatening the world around us. A biotech process has been developed and demonstrated that effectively remove and treat volatile disinfection by-products from drinking water. The process strips low concentration disinfection by-products, such as trihalomethanes, that are formed during the chlori

High content screening (HCS) is the convergence between cell-based assays, high-resolution fluorescence imaging, phase-contrast imaging of fixed- or live-cell assays, tissues and small organisms. It has been widely adopted in the pharmaceutical and biotech industries for target identification and validation and as secondary screens to reveal potential toxicities or to elucidate a drugs mechanism of action. By using the ImageXpress® Micro XLS System HCS, the complex network of key players controlling proliferation and apoptosis can be reduced to several sentinel markers for analysis. Cell proliferation and apoptosis are two key areas in cell biology and drug discovery research. Understanding the signaling pathways in cell proliferation and apoptosis is important for new therapeutic discovery because the imbalance between these two events is predominant in the progression of many human diseases, including cancer. The DNA binding dye DAPI is used to determine the nuclear size and nuclear morphology as well as cell cycle phases by DNA content. Images together with MetaXpress® analysis results provide a convenient and easy to use solution to high volume image management. In particular, HCS platform is beginning to have an important impact on early drug discovery, basic research in systems cell biology, and is expected to play a role in personalized medicine or revealing off-target drug effects.

Improving Agrobacterium -mediated transformation frequency and event quality by increasing binary plasmid copy number and appropriate strain selection is reported in an elite maize cultivar. Agrobacterium-mediated maize transformation is a well-established method for gene testing and for introducing useful traits in a commercial biotech product pipeline. To develop a highly efficient maize transformation system, we investigated the effect of two Agrobacterium tumefaciens strains and three different binary plasmid origins of replication (ORI) on transformation frequency, vector backbone insertion, single copy event frequency (percentage of events which are single copy for all transgenes), quality event frequency (percentage of single copy events with no vector backbone insertions among all events generated; QE) and usable event quality frequency (transformation frequency times QE frequency; UE) in an elite maize cultivar PHR03. Agrobacterium strain AGL0 gave a higher transformation frequency, but a reduced QE frequency than LBA4404 due to a higher number of vector backbone insertions. Higher binary plasmid copy number positively correlated with transformation frequency and usable event recovery. The above findings can be exploited to develop high-throughput transformation protocols, improve the quality of transgenic events in maize and other plants.

Bangladesh is on the verge of adopting genetically modified (GM) crops for commercial cultivation and consumption as feed and food. Most of the laboratories are engaged in tissue culture and molecular characterization on plants, whereas some have started living modified organism research with shortages of trained manpower, infrastructure, and funding. Nutritionally improved Golden Rice, biotech brinjal, and late blight-resistant potato are in contained trials in a greenhouse, and potato ring spot virus-resistant papaya is in the process of approval for a field trial. The government has taken some initiative in support of GM organism research, which include the formation of a Biotechnology Department in all institutes and the formation of the apex body, the National Task Force Committee on Biotechnology of Bangladesh under the chairpersonship of the Prime Minister. Biosafety policy guidelines and related aspects of biotechnology issues have been approved, and the laws are in the process of being promulgated. Being a party to the Cartagena Protocol, proper biosafety measures are regulated by the appropriate authority as stated. Although there are no laws made yet directly for biosafety of GM crops/foods, the relevant laws on agriculture, medicine, food, import, trade, environment, etc. may suffice and explain the situation.

The growing number of biotech crops with novel genetic elements increasingly complicates the detection of genetically modified organisms (GMOs) in food and feed samples using conventional screening methods. Unauthorized GMOs (UGMOs) in food and feed are currently identified through combining GMO element screening with sequencing the DNA flanking these elements. In this study, a specific and sensitive qPCR assay was developed for vip3A element detection based on the vip3Aa20 coding sequences of the recently marketed MIR162 maize and COT102 cotton. Furthermore, SiteFinding-PCR in combination with Sanger, Illumina or Pacific BioSciences (PacBio) sequencing was performed targeting the flanking DNA of the vip3Aa20 element in MIR162. De novo assembly and Basic Local Alignment Search Tool searches were used to mimic UGMO identification. PacBio data resulted in relatively long contigs in the upstream (1,326 nucleotides (nt); 95 % identity) and downstream (1,135 nt; 92 % identity) regions, whereas Illumina data resulted in two smaller contigs of 858 and 1,038 nt with higher sequence identity (>99 % identity). Both approaches outperformed Sanger sequencing, underlining the potential for next-generation sequencing in UGMO identification.

Aluminum oxide surfaces are of utmost interest in different biotech applications, in particular for their use as adjuvants (i.e., booster of the immune response against infectious agents in vaccines production). In this framework, imogolite clays combine the chemical flexibility of an exposed alumina surface with 1D nanostructure. This work reports on the interaction between amino acids and imogolite, using turbidimetry, ζ-potential measurements, and Fourier transform infrared spectroscopy as main characterization tools. Amino acids with different side chain functional groups were investigated, showing that glutamic acid (Glu) has the strongest affinity for the imogolite surface. This was exploited to prepare a composite material made of a synthetic surfactant bearing a Glu polar head and a hydrophobic C 12 alkyl tail, adsorbed onto the surface of imogolite. The adsorption of a model drug (rhodamine B isothiocyanate) by the hybrid was evaluated both in water and in physiological saline conditions. The findings of this paper suggest that the combination between the glutamate headgroup and imogolite represents a promising platform for the fabrication of hybrid nanostructures with tailored functionalities.
Full Text Available ABSTRACT Recent research reports the importance of preserving plants in Brazilian semiarid regions, in this context, the scientific literature has reported different pharmacological studies from plant extracts with an antifungal potential, coming from forest species that can contribute as a control and management strategy in the transmission of phytopathogens. This study aimed to evaluate the effect of biotech treatments in controlling the transmission of Colletotrichum sp. in seeds of S. obtusifolium. In this study, 100 seeds were subjected to the following preventive treatments: fungicide Captan®, extract of Caesalpinia ferrea Mart. Ex. Tul., and biological control with Trichoderma spp. The biological control with Trichoderma spp. and the alternative control using C. ferrea extract provided a greater protection to seeds and seedlings of S. obtusifolium facing the transmissibility of Colletotrichum sp.The treatment based on plant extract is more efficient for this purpose only in large seeds and does not interfere on the germination percentage and speed. Therefore it is necessary to perform other studies with Trichoderma spp. and C. ferrea extract to test different doses of these products.
The development of highly functionalized porous materials for protein separation is important for biotech processes. We report the preparation of highly porous polytriazole with sulfonic acid functionalization. The resulting ion exchange membranes are selective for protein adsorption. The starting material was a hydroxyl-functionalized polytriazole, which is an advantageous platform for further modification. The polymer was dissolved in a mixture of 1-ethyl-3-methylimidazolium acetate ([C2mim]OAc) and dimethyl carbonate (DMC), which can be both considered green solvents. The polymer solubilization was only possible due to an interesting effect of cosolvency, which is discussed, based in phase diagrams. Membranes were prepared by solution casting, followed by immersion in a non-solvent bath. We then grafted sulfone groups on the membranes, by reacting the hydroxyl groups with 1,3-propane sultone and 1,4-butane sultone. Lysozyme adsorption was successfully evaluated. Membranes modified with 1,4-butane sultone adsorbed more protein than those with 1,3-propane sultone.

Spain launched its own strategy on bioeconomy in January 2016 aiming at boosting a bioeconomy based on the sustainable and efficient production and use of biological resources. It highlights global societal challenges related with agricultural and biotechnological sciences in Spain and the great dynamism of the private sectors involved, particularly the agri-food, biotech and biomass sectors. The targeted sectors are food, agriculture and forestry, conditioned by water availability. It also includes the production of those industrial bioproducts and bioenergy obtained from the use and valorisation of wastes and residues and other non-conventional sources of biomass, in a circular economy. The strategy also puts a focus on rural and coastal development through several uses and services linked to ecosystems. The capacity to generate know-how in this area and the promotion of public and private collaboration are important pillars in order to enhance existing value chains and to create new ones. The strategy is led by R&I and Agriculture, Food and Environment policy managers and largely supported at regional level too. The strategic objective is the maintenance of the bioeconomy as an essential part of Spanish economy to contribute to the economic growth by creating new jobs and fostering investments.

While most agree the synchrotron will be a boost for Australian science, the author reports on concerns about the cost of building and operating the project Biotech industry representatives want to know how that $100 million will be used and want to see the government's justification for pouring more than a third of its total technology budget for 2001/2 into the synchrotron. They, and the opposition, also want to know where the private money will come from to make up the balance or whether the state will ultimately have to pitch in the rest itself. Indeed, an Auditor-General's report released last week warned of the need for comprehensive financial risk management of the facility. The National Synchrotron, to be built at Monash University, will be a hollow ring of about 60 metres diameter and initially housing nine beamlines, each capable of performing independent experiments simultaneously. According to Dr Richard Garrett, director of the Australian Synchrotron Research Program (http://www.ansto.gov.au/natfac/asrp.html) projection reports had indicated the local synchrotron user community would expand from about 350 researchers today to about 1200 by the time the National Synchrotron is built, with demand steadily increasing in the years following its completion

Photodynamic therapy (PDT) utilizes optical energy to activate a pre-administered photosensitizer drug to achieve a localized tumor control. In the presented study, PDT mediated with a second-generation photosensitizer, WST09 (TOOKAD, Steba Biotech, The Netherlands), is investigated as an alternative therapy in the treatment of prostate cancer. In vivo canine prostate is used as the animal model. PDT was performed by irradiating the surgically exposed prostates both superficially and interstitially with a diode laser (763 nm) to activate the intra-operatively i.v. infused photosensitizer. During light irradiation, tissue optical properties, and temperature were monitored. During the one-week to 3-month period post PDT treatment, the dogs recovered well with little or no complications. The prostates were harvested and subjected to histopathological evaluations. Maximum lesion size of over 3 cm in dimension could be achieved with a single treatment, suggesting the therapy is extremely effective in destroying prostatic tissue. Although we found there was loss of epithelial lining in prostatic urethra, there was no evidence it had caused urinary tract side effects as reported in those studies utilizing transurethral irradiation. In conclusion, we found second generation photosensitizer WST09 mediated PDT may provide an excellent alternative to treat prostate cancer.

In this study, photodynamic therapy (PDT) mediated with a novel, second generation photosensitizer Tookad (palladium-bacteriopheophorbide, WST09, STEBA Biotech, France), is investigated as an alternative modality in the treatment of prostate cancer. In vivo normal canine prostate and spontaneous advanced prostate cancer are used as the animal model. PDT was performed by irradiating the surgically exposed prostates with a diode laser (763 nm, 150 mW/cm) to activate the i.v. infused photosensitizer. The effects of drug concentration, drug-light interval, and light fluence rate on the PDT efficacy were studied. The prostates and adjacent tissues (bladder and underlying colon) were harvested and subjected to histopathological examination. During the one-week to 3-month period post PDT treatment, the dogs recovered well with little or no urethral complications. Prostatic urethra and prostate adjacent tissues (bladder and underlying colon) were well preserved. Light irradiation delivered during drug infusion or within 15 min post drug infusion induced the similar extend of damages. PDT induced prostate lesions in both normal and cancerous prostate were characterized by marked hemorrhagic necrosis and atrophy. Maximum lesion size of over 3 cm in dimension could be achieved with a single 1-cm interstitial treatment, suggesting the therapy is very effective in ablating cancerous prostatic tissue. In conclusion, the second generation photosensitizer Tookad mediated PDT may provide an effective alternative to treat prostate cancer.

The aims of this study were to evaluate the serological response to treatment with staphylococcal vaccine in fibromyalgia/chronic fatigue syndrome patients and to explore the relationship between serological response and clinical effect. Twenty-eight patients, half of whom served as controls, were recruited from a 6-month randomised trial in which repeated administration of the staphylococcal toxoid vaccine Staphypan Berna (Berna Biotech, Switzerland) was tested against placebo. Antibody status against extracellular toxins/enzymes, cell-wall components, and enterotoxins was evaluated at baseline and at endpoint. The clinical response to treatment was recorded in rating scales. In the group receiving active treatment, significant serological changes were recorded, whereas no significant changes were found in controls. Treatment led to a significantly increased capacity of serum to neutralise alpha-toxin and a significant increase in serum IgG to alpha-toxin and lipase. Furthermore, the increase in these parameters combined paralleled the improvement in clinical outcome. Thus, the greater the serological response, the greater was the clinical effect. In conclusion, this explorative study has shown that repeated administration of the Staphypan Berna vaccine in patients with fibromyalgia/chronic fatigue syndrome causes a serological response to several staphylococcal antigens, particularly to certain extracellular toxins and enzymes. The results further show that this response is related to the clinical outcome of treatment.

Engineering robust microbes for the biotech industry typically requires high-level, genetically stable expression of heterologous genes and pathways. Although plasmids have been used for this task, fundamental issues concerning their genetic stability have not been adequately addressed. Here we describe chemically inducible chromosomal evolution (CIChE), a plasmid-free, high gene copy expression system for engineering Escherichia coli. CIChE uses E. coli recA homologous recombination to evolve a chromosome with approximately 40 consecutive copies of a recombinant pathway. Pathway copy number is stabilized by recA knockout, and the resulting engineered strain requires no selection markers and is unaffected by plasmid instabilities. Comparison of CIChE-engineered strains with equivalent plasmids revealed that CIChE improved genetic stability approximately tenfold and growth phase-specific productivity approximately fourfold for a strain producing the high metabolic burden-biopolymer poly-3-hydroxybutyrate. We also increased the yield of the nutraceutical lycopene by 60%. CIChE should be applicable in many organisms, as it only requires having targeted genomic integration methods and a recA homolog.

The business model for medical therapy development has changed drastically. Large companies that once conducted their own Research and Development (R&D) and funded all the preclinical studies, all phases of clinical development and marketing of the products are increasingly turning to others for more and more of the earlier work in hopes of being able to in-license a de-risked program well downstream, take it through the final phases of clinical development and into the marketplace. This new paradigm has required patient-advocacy foundations, especially in the rare-disease space, to become far more effective in building relationships with all the players along the therapy-development pathway -- academic scientists, government agencies, other foundations with overlapping interests, biotechs, small biopharmaceutical entities and even the larger industry companies. From the perspective of the patient-advocacy community, these increasingly essential public-private partnerships have taken on the nature of what could be called joint-venture philanthropy and involve a broad spectrum of collaborations and financial relationships between foundations and industry partners that are not without concerns about potential conflicts of interest.
Full Text Available Various authors have shown the importance of collaborative relationships for inter-organizational performance, the mode of governance or the trajectory of biotechnology companies. Most of these works analyze the exclusive contractual agreements between companies and their main relationships among individuals. We show that this purely economic approach presents a major limitation: the nature of contractual relationships does not explore in detail how players cooperate. We propose to extend the study of these inter-organizational social relations, seen through the resource exchange in inter-individual. An empirical study on the leaders of the biotechnology industry in the area of human health in France has allowed us to map their relationships and resources they exchange them. Our results confirm the existence of a system of exchange dense and multiple. It presents a hierarchical distribution of various types of resources, where the centre is different from the periphery relations denser, more numerous and more reciprocal. However, comparative analysis of different networks reveals that the relationships of the board are highly centralized, while those of friendship following a more even distribution. We suggest that this phenomenon is part of a compensation mechanism to less central actors to maintain inter-organizational relationships. Finally, two standards of the cooperation process, revealed by the relational behaviour of actors, have been discovered. We suggest that they reflect in part the difficult process of adjustment that must cross a science project out of the realm of academic research and develop in a private structure: the biotech company.

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 ability of whole cells to catalyse multistep reactions, often yielding synthetically demanding compounds later used by industrial biotech or pharma, makes them an indispensable tool of synthetic chemistry. The complex reaction network employed by cellular catalysts and the still only moderate predictive power of modelling approaches leaves this tool challenging to engineer. Frequently, large libraries of semi-rationally generated variants are sampled in high-throughput mode in order to then identify improved catalysts. We present a method for space- and time-efficient processing of very large libraries (10 7 ) of recombinant cellular catalysts, in which the phenotypic characterisation and the isolation of positive variants for the entire library is done within one minute in a single, highly parallelized operation. Specifically, product formation in nanolitre-sized cultivation vessels is sensed and translated into the formation of catalase as a reporter protein. Exposure to hydrogen peroxide leads to oxygen gas formation and thus to a density shift of the cultivation vessel. Exploiting Archimedes' principle, this density shift and the resulting upward buoyancy force can be used for batch-wise library sampling. We demonstrate the potential of the method for both, screening and selection protocols, and envision a wide applicability of the system for biosensor-based assays.

Full Text Available The risks of biotechnology development are higher proportions of issues than is believed and that proportionately receive little attention from the law. The risk, as a potentiality, appears to be of little concern when compared to the surrounding advantages. The absence of intense discussions in this regard turns out to be disturbing, especially when the biotechnological advances reaches unknown dimensions. This paper presents an interdisciplinary analysis of Law branches pointing to the appreciation of the Agricultural Law and its interaction with the Law of Disasters can be really enhancing and promoting a sustainable development. The research brings considerations about the search for the development of technologies that can combat endemic hunger serves as positive motivation and at the same time, market the Capital. The conclusion, always under construction, points out the need for publicity and intensification of jus-agraristas debates within the Law of Disasters, especially when it comes to biotech disasters. It is observed that the Agrarian Law has important contributions to the Law of Disasters and both, to build a sustainable biotechnology development.

The possibility to buy standardized external services or even new and innovative methods within drug discovery has increased dramatically during the last decades. Service providers are able to provide timely and efficient solutions to any given problem within preclinical research. The outsourcing behavior depends on the specific company type. Generally, the outsourcing level of emerging pharmaceutical and biotechnology companies is much higher than established companies due to low or missing internal resources. Whereas the "make-or-buy" decisions of large and fully integrated pharmaceutical companies are mainly competency driven, those of mid-size and small pharmaceutical, as well as biotech companies show a specific combination of cost/capacity and competency. The three different cooperation models "price competition", "project selection," and "strategic partnership" were identified. For all types of companies, the cooperation model of "strategic partnership" offers access to high-level expertise while reducing fixed costs and complexity. This was shown using chemical synthesis as an example but is also true for other areas of preclinical research.

We wanted to determine the technical and clinical efficacy of placing a self-expandable PTFE-covered nitinol stent for the management of inoperable malignant biliary obstruction. Thirty six patients with inoperable malignant biliary obstructions were treated by placement of self-expandable PTFE-covered nitinol stents (S and G Biotech Corporation, Seongnam, Korea). Clinical evaluation was done with assessment of the serum bilirubin and alkaline phosphatase levels, which were measured before and after stent placement within 1 week, at 1 month and at 3 months. The patient survival rate and stent patency rate were calculated with performing Kaplan-Meier survival analysis. Successful stent placement was achieved in all the patients without procedure-related complication. Pancreatitis as an early complication occurred in two cases. The serum bilirubin and alkaline phosphatase levels were significantly decreased after the procedure. During the follow-up, recurrent obstructive jaundice occurred in six cases; stent migration occurred in four cases and tumor overgrowth occurred in two cases. The survival rates were 97%, 80%, 67% and 59% at 1, 3, 6 and 9 months, respectively. The stent patency rates were 96%, 92%, 86% and 86% at 1, 3, 6 and 9 months, respectively. Self-expandable PTFE-covered nitinol stent placement seems to be technically feasible and effective for the palliative treatment of malignant biliary obstruction.
Medicine is evolving every day in its operating procedures and the services offered to patients, emphasizing personalized medicine, safety and medical benefits. The individual patient is more than ever the hub of healthcare organization. Medical innovation is thus a public health priority. However it requires an accurate assessment of medical utility and risk-benefit ratios, and in-depth analysis of economic and organizational impacts. Ten years of experience in the Paris Biotech Santé company incubator has identified key actions for effective support of research projects and the success of innovative companies. Strong expertise is needed to prepare development plans, ensure compliance with regulatory requirements and obtain research funding. During its first decade, this incubator has created 87 innovative companies employing 1500 people, raised more than 90 million euros of funding, and reached a cumulative company value of 1200 million euros. Key factors of success have been identified, but an analysis of the causes of failure shows that operational adjustments are mandatory, particularly a strong commitment from medical experts, in order to promote access to new and useful products for patients while at the same time assessing their social impact.

Although essential to numerous biotech applications, knowledge of molecular recognition by arginine-rich motifs in live cells remains limited. 1 H, 15 N HSQC and 19 F NMR spectroscopies were used to investigate the effects of C-terminal -GR n (n = 1-5) motifs on GB1 interactions in Escherichia coli cells and cell extracts. While the "biologically inert" GB1 yields high-quality in-cell spectra, the -GR n fusions with n = 4 or 5 were undetectable. This result suggests that a tetra-arginine motif is sufficient to drive interactions between a test protein and macromolecules in the E. coli cytoplasm. The inclusion of a 12 residue flexible linker between GB1 and the -GR 5 motif did not improve detection of the "inert" domain. In contrast, all of the constructs were detectable in cell lysates and extracts, suggesting that the arginine-mediated complexes were weak. Together these data reveal the significance of weak interactions between short arginine-rich motifs and the E. coli cytoplasm and demonstrate the potential of such motifs to modify protein interactions in living cells. These interactions must be considered in the design of (in vivo) nanoscale assemblies that rely on arginine-rich sequences.

Agrobacterium tumefaciens is widely used as a versatile tool for development of stably transformed model plants and crops. However, the development of Agrobacterium based transient plant transformation methods attracted substantial attention in recent years. Transient transformation methods offer several applications advancing stable transformations such as rapid and scalable recombinant protein production and in planta functional genomics studies. Herein, we highlight Agrobacterium and plant genetics factors affecting transfer of T-DNA from Agrobacterium into the plant cell nucleus and subsequent transient transgene expression. We also review recent methods concerning Agrobacterium mediated transient transformation of model plants and crops and outline key physical, physiological and genetic factors leading to their successful establishment. Of interest are especially Agrobacterium based reverse genetics studies in economically important crops relying on use of RNA interference (RNAi) or virus-induced gene silencing (VIGS) technology. The applications of Agrobacterium based transient plant transformation technology in biotech industry are presented in thorough detail. These involve production of recombinant proteins (plantibodies, vaccines and therapeutics) and effectoromics-assisted breeding of late blight resistance in potato. In addition, we also discuss biotechnological potential of recombinant GFP technology and present own examples of successful Agrobacterium mediated transient plant transformations.

The 1980s and 1990s saw a major expansion of biotechnology into new areas of science including genomics and recombinant technologies. This was coupled to the widespread emergence of academics into the commercial sector as they were encouraged to spin out companies or commercialize their intellectual property. There were many opportunities to raise investment, and extraordinary success stories were prominent across many areas of technology. The field of plant biotechnology for manufacturing recombinant pharmaceuticals (molecular pharming) emerged and was developed in this period. Like other biotechnologies, this was an exciting new development which offered some very obvious benefits and commercial advantages. In particularly, plant molecular pharming represented a highly novel and potentially disruptive manufacturing technology for recombinant proteins. Twenty-five years on, a series of interviews with senior members of sixteen of the most prominent companies involved in the field provides insight into the original drivers for commercialization, strategic thinking and planning behind key commercial decisions and an insider view into the major reasons for commercial success or failure. These observations and recurring themes identified across a number of commercial ventures remain relevant today, as new biotech companies continue to spin out of the world of academia. © 2015 Society for Experimental Biology, Association of Applied Biologists and John Wiley & Sons Ltd.

Pharmaceutical biotechnology has a long tradition and is rooted in the last century, first exemplified by penicillin and streptomycin as low molecular weight biosynthetic compounds. Today, pharmaceutical biotechnology still has its fundamentals in fermentation and bioprocessing, but the paradigmatic change affected by biotechnology and pharmaceutical sciences has led to an updated definition. The biotechnology revolution redrew the research, development, production and even marketing processes of drugs. Powerful new instruments and biotechnology related scientific disciplines (genomics, proteomics) make it possible to examine and exploit the behavior of proteins and molecules. Recombinant DNA (rDNA) technologies (genetic, protein, and metabolic engineering) allow the production of a wide range of peptides, proteins, and biochemicals from naturally nonproducing cells. This technology, now approximately 25 years old, is becoming one of the most important technologies developed in the 20(th) century. Pharmaceutical products and industrial enzymes were the first biotech products on the world market made by means of rDNA. Despite important advances regarding rDNA applications in mammalian cells, yeasts still represent attractive hosts for the production of heterologous proteins. In this review we describe these processes.

In this study, United States, China, India, United Kingdom, Nigeria, Egypt, Brazil, Italy, Germany, Taiwan, Australia, Canada and Mexico were selected to represent the global community. This enabled an overview of solid waste management worldwide and between developed and developing countries. These are countries that feature most in the International Conference on Solid Waste Technology and Management (ICSW) over the past 20 years. A total of 1452 articles directly on solid waste management and technology were reviewed and credited to their original country of research. Results show significant solid waste research potentials globally, with the United States leading by 373 articles, followed by India with 230 articles. The rest of the countries are ranked in the order of: UK > Taiwan > Brazil > Nigeria > Italy > Japan > China > Canada > Germany >Mexico > Egypt > Australia. Global capacity in solid waste management options is in the order of: Waste characterisation-management > waste biotech/composting > waste to landfill > waste recovery/reduction > waste in construction > waste recycling > waste treatment-reuse-storage > waste to energy > waste dumping > waste education/public participation/policy. It is observed that the solid waste research potential is not a measure of solid waste management capacity. The results show more significant research impacts on solid waste management in developed countries than in developing countries where economy, technology and society factors are not strong. This article is targeted to motivate similar study in each country, using solid waste research articles from other streamed databases to measure research impacts on solid waste management.
The expression "Genetically Modified Organisms" was coined to indicate a group of agricultural products (mostly crops and vegetables), modified through direct DNA recombination in order to obtain useful phenotypic traits or to inhibit undesirable characteristics. But the border between rDNA ("GMO") and other biotech methods is blurred. Moreover, the ill-assorted group is frequently charged with having peculiar, negative characteristics: many activists, part of the public and a few social science scholars think that "GMOs" are all dubious, even inherently dangerous. However, theoretical justifications of this alleged problematic nature which is supposed to be necessarily linked to the "splicing" of DNA, only when applied to agricultural products, are missing: the only text which tries to go in depth on the subject, an article by biologist Barry Commoner, takes aim at the wrong target, misunderstanding the Central Dogma. "GMO" is a term that has no clear reference, let alone in a detrimental sense. The only attempt to give it epistemological dignity fails.

We previously presented the YM500 database, which contains >8000 small RNA sequencing (smRNA-seq) data sets and integrated analysis results for various cancer miRNome studies. In the updated YM500v3 database (http://ngs.ym.edu.tw/ym500/) presented herein, we not only focus on miRNAs but also on other functional small non-coding RNAs (sncRNAs), such as PIWI-interacting RNAs (piRNAs), tRNA-derived fragments (tRFs), small nuclear RNAs (snRNAs) and small nucleolar RNAs (snoRNAs). There is growing knowledge of the role of sncRNAs in gene regulation and tumorigenesis. We have also incorporated >10 000 cancer-related RNA-seq and >3000 more smRNA-seq data sets into the YM500v3 database. Furthermore, there are two main new sections, 'Survival' and 'Cancer', in this updated version. The 'Survival' section provides the survival analysis results in all cancer types or in a user-defined group of samples for a specific sncRNA. The 'Cancer' section provides the results of differential expression analyses, miRNA-gene interactions and cancer miRNA-related pathways. In the 'Expression' section, sncRNA expression profiles across cancer and sample types are newly provided. Cancer-related sncRNAs hold potential for both biotech applications and basic research. © The Author(s) 2016. Published by Oxford University Press on behalf of Nucleic Acids Research.

In particular Lombardy region accounts for 40% of total rice cultivation and the case study in object accounts for 3.2% of Lombardy total rice area (2773 ha. Starting from 2012, through a regional project titled Buono, Sano e Vicino (good, healthy and close, Riso e Rane rural district supported local rice farmers in developing innovation in rice production and promoting an alternative supply chain to increase farmers bargaining power and promote new market strategies. More specifically, the innovation introduced is a new biotech method for variety certification, named DNA controllato (DNA tested. In the first step of the project, the attention was focused on an Italian traditional variety of rice: Carnaroli rice. Thanks to a commercial agreement with one of the most important large retailers in Lombardy, the Riso e Rane rice is offered for sale both in the traditional and wholegrain version. In this context, this work aims to evaluate the determinants of consumer’s quality perception of this product, through a preference study of the commercial rice package. Preliminary results reveal that consumers perceive information about origin, local food-system and tradition more easily than DNA tested certification. In conclusion, this work contributes to evaluate the role of bio economy applications to the food sector and offers new insights for the debate about the relationships between tradition and innovation.

El análisis apunta a evidenciar cómo la estrategia de apropiación de los resultados de las innovaciones tecnológicas de la firma se basa en la articulación de distintos mecanismos y, al ser la actividad de innovación realizada con el aporte de fuentes externas y públicas de conocimiento, dicha estrategia debe tener en cuenta los riesgos que derivan de este rasgo constitutivo de la innovación. La cooperación público-privada para la innovación genera efectos variados sobre cada uno de los mecanismos de apropiación y, por tanto, las características específicas que asume la misma son relevantes para evaluar cuáles son sus efectos sobre la estrategia de apropiación de la empresa.
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.

Colleges and universities are under increased pressure from internal and external constituencies for increased innovation and responsiveness. Entrepreneurial private industry models such as start-up businesses, corporate ventures and spin-off organizations have been recognized for their ability to quickly adapt to changing business environments and rapidly innovate to take advantage of new opportunities. This case study investigates these claims with regard to a start-up university founded with the identity of an entrepreneurial, interdisciplinary institution that prepares graduate level students for leadership careers as entrepreneurs in the bio-tech industry. By interviewing twenty-four administrators, faculty, and members of the Board of Trustees, including all but one of the founding full-time faculty, I present an "insider's" depiction of the lived experience of those most closely associated with the founding and subsequent institution building of this unique higher education organization. Initial chapters present a theory of higher education organizations, derived from Birnbaum (1988) and Bolman and Deal (1991), as driven by two primary tasks: resolving identity and establishing power and resources in relation to that identity. I also present Russell and Russell's (1992) theory of "entrepreneurial posture" in relation to a higher education organization. Subsequent chapters analyze the start-up university's environment, strategy, culture, and structure within the framework of the two primary organizational tasks and Russell and Russell's (1992) definition of an entrepreneurial organization.

The GRIN technologies (-geno, -robo, -info, -nano) promise to change the inner constitution of human body and its own existence. This transformation involves the structure of our lives and represent a brave new world that we have to explore and to manage. In this sense, the traditional tools of humanism seems very inadequate to think the biotech century and there is a strong demand of a new thought for the evolution and the concrete history of life. The posthuman philosophy tries to take this new path of human existence in all of its novelty since GRIN technologies seem to promise new and unexpected paths of evolution to living beings and, above all, man. For this, the post-human thought, as we see, is a new anthropological overview on the concrete evolution of human being, an overview that involves an epistemological revolution of the categories that humanism uses to conceptualize the journey that divides the Homo sapiens from the man. But, is this right?

The objective of this research was to study the efficacy and safety of capsule 'UB03' to treat patients with Irritable Bowel Syndrome (IBS). Thirty patients with Rome II IBS were assigned to receive capsule 'UB03' (10 billion lyophilised bacteria and yeast/capsule produced by Unique Biotech Limited, India) twice daily for 90 days. Assessment of IBS was carried out according with Rome II criteria and their severity for 90 days of treatment with an interval of 30 days. Complete haemogram, serum glutamic pyruvic transaminase, serum creatinine were performed as a part of safety evaluation at the time of inclusion and after 90 days of treatment. There was significant improvement in frequency of defecation (23%), consistency of stool, abdominal discomfort, bloating and flatulence. However, there was no significant change in abdominal pain and mucus in stool. This trial demonstrates that the consumption of capsule 'UB03' containing potential probiotic strains is found to be effective and safe for the treatment of patients with IBS.

The pharmaceutical industry is undergoing major shifts due to changing macro and micro factors. As the industry is highly capital intensive and patents are expiring, the outlook is on generating inorganic growth, mainly through M&A. Using the income valuation approach, one analyses two completed deals in 2016 above 1bn USD. Thereafter one outlines the main motives behind M&A deals and concluded by discussing whether M&A harms medical innovations. Areas covered: The paper is based on empirical study questioning existing literature in order to critically analyse valuation and the strategical orientation of pharmaceutical companies Expert commentary: Pharmaceutical companies understand the changing market conditions and favour their expertise. The restructuring of the industry moves to small niche companies (I.e. Biopharma or biotech companies) researching key innovations and big companies purchasing them to develop them, create clinical trials and distribute them as this is a costly manner Conclusion: One can expect more M&A deals during the next years focusing on value rather than volume. Pharmaceutical players resilient to the market changes may survive if they change their business model from a traditional vertical one to outsourcing and diversification including external players.

Every major biopharmaceutical company incorporates a protein crystallography unit that is central to its structure-based drug discovery efforts. Yet these capabilities are rarely leveraged toward the formal higher order structural characterization that is so challenging but integral to large-scale biologics manufacturing. Although the biotech industry laments the shortcomings of its favored biophysical techniques, x-ray crystallography is not even considered for drug development. Why not? We suggest that this is due, at least in part, to outdated thinking (for a recent industry-wide survey, see Gabrielson JP, Weiss IV WF. Technical decision-making with higher order structure data: starting a new dialogue. J Pharm Sci. 2015;104(4):1240-1245). We examine some myths surrounding protein crystallography and highlight the inherent properties of protein crystals (molecular identity, biochemical purity, conformational uniformity, and macromolecular crowding) as having practicable commonalities with today's patient-focused liquid drug products. In the new millennium, protein crystallography has become essentially a routine analytical test. Its application may aid the identification of better candidate molecules that are more amenable to high-concentration processing, formulation, and analysis thereby helping to make biologics drug development quicker, simpler, and cheaper.

In Botswana, approximately 40% of the population live in rural areas and derive most of their livelihood from agriculture by keeping livestock and practising arable farming. Due to the nature of their farming practises livestock and crops are exposed to diseases and environmental stresses. These challenges offer opportunities for application of biotechnology to develop adaptable materials to the country's environment. On the other hand, the perceived risk of genetically modified organisms (GMOs) has dimmed the promise of the technology for its application in agriculture. This calls for a holistic approach to the application of biotechnology to address issues of biosafety of GMOs. We have therefore assessed the potentials, challenges and opportunities to apply biotechnology with specific emphasis on agriculture, taking cognisance of requirement for its research, development and application in research and teaching institutions. In order to achieve this, resource availability, infrastructure, human and laboratory requirements were analyzed. The analysis revealed that the country has the capacity to carry out research in biotechnology in the development and production of genetically modified crops for food and fodder crops. These will include gene discovery, genetic transformation and development of systems to comply with the world regulatory framework on biosafety. In view of the challenges facing the country in agriculture, first generation biotech crops could be released for production. Novel GM products for development may include disease diagnosis kits, animal disease vaccines, and nutrient use efficiency, drought, and pest and disease resistant food and fodder crops.

: Previous studies have demonstrated that >90% of HIV-uninfected infants serorevert, as seen in the results of enzyme immunoassay (EIA) testing by 12 months of age, making it feasible to confirm or rule out infection. We assessed the reliability of EIA in a cohort of Vietnamese infants. : HIV-exposed, uninfected infants enrolled in a parent diagnostic and monitoring study from February 2005 through August 2006 were eligible for inclusion in a prospective cohort study of HIV-EIA performance. Testing using 2 standard assays (Genscreen HIV 1/2 version 2, Bio-Rad; Murex 1.2.0, Murex Biotech) was initiated at 12 months of age. Infants were categorized as EIA-negative (seroreverted; negative Genscreen), EIA-indeterminate (positive Genscreen, negative Murex), or EIA-positive (Genscreen and Murex positive). : Of 273 infants included in the study, 59 (22%) were EIA-negative at 12 months, 131 (48%) were indeterminate, and 83 (30%) were EIA-positive; specificity 21.6 (95% confidence interval: 16.6, 26.3). Infants with positive EIAs at 12 months were 74% more likely than EIA-indeterminate infants to test indeterminate or positive at 18 months (risk ratio, 1.74, 95% confidence interval: 1.15, 2.64; P = 0.03). : Expectations regarding infant seroreversion by standard EIAs should be reassessed to reflect potential cross-regional differences in their performance.

A mutation breeding is to use physical or chemical mutagens to induce mutagenesis, followed by individual selections with favorable traits. The mutation breeding has many advantages over other breeding methods, which include the usefulness for improving one or two inferior characteristics, applications to broad species with different reproductive systems or to diverse plant materials, native or plant introduction with narrow genetic background, time and cost-effectiveness, and valuable mutant resources for genomics researches. Recent applications of the radiation breeding techniques to developments of flowering plants or food crops with improved functional constituents heightened the public's interests in agriculture and in our genetic resources and seed industries. The goals of this project, therefore, include achieving advances in domestic seed industries and agricultural productivities by developing and using new radiation mutants with favored traits, protecting an intellectual property right of domestic seeds or germplasms, and sharing the valuable mutants and mutated gene information for the genomics and biotech researches that eventually leads to economic benefits

The functionality of a newly developed silicone oil-free (SOF) syringe system, of which the plunger stopper is coated by a novel coating technology (i-coating™), was assessed. By scanning electron microscopy observations and other analysis, it was confirmed that the plunger stopper surface was uniformly covered with the designed chemical composition. A microflow imaging analysis showed that the SOF system drastically reduced both silicone oil (SO) doplets and oil-induced aggregations in a model protein formulation, whereas a large number of subvisible particles and protein aggregations were formed when a SO system was used. Satisfactory container closure integrity (CCI) was confirmed by means of dye and microorganism penetration studies. Furthermore, no significant difference between the break loose and gliding forces was observed in the former, and stability studies revealed that the SOF system could perfectly show the aging independence in break loose force observed in the SO system. The results suggest that the introduced novel SOF system has a great potential and represents an alternative that can achieve very low subvisible particles, secure CCI, and the absence of a break loose force. In particular, no risk of SO-induced aggregation can bring additional value in the highly sensitive biotech drug market. © 2014 Wiley Periodicals, Inc. and the American Pharmacists Association J Pharm Sci 103:1520–1528, 2014 PMID:24643749

Full Text Available Background. Salivary constituents have a wide range of functions including oral calcium homeostasis. Salivary proteins such as statherin inhibit crystal growth of calcium phosphate in supersaturated solutions and interact with several oral bacteria to adsorb on hydroxyapatite. Concurrently, saliva, which is supersaturated with respect to calcium phosphates, is the driving force for plaque mineralization and formation of calculus. Thus, the aim of the present study was to estimate and correlate salivary statherin and calcium concentration to the dental calculus formation. Methods. A cross-sectional study was conducted to assess the relationship between salivary statherin, calcium, and dental calculus among 70 subjects, aged 20–55 years. Subjects were divided into 3 groups based on the calculus scores as interpreted by Calculus Index which was followed by collection of whole saliva using Super•SAL™. Salivary calcium levels were assessed by calorimetric method using Calcium Assay kit (Cayman Chemical, Michigan, USA and statherin levels by using ELISA Kit (Cusabio Biotech. Results. Statherin levels showed a weak negative correlation with the calcium levels and with calculus formation. The mean salivary statherin and calcium concentration were found to be 0.96 μg/ml and 3.87 mg/ml, respectively. Salivary statherin levels differed significantly among the three groups (p<0.05. Conclusions. Our preliminary data indicates that statherin could possibly play a role in the formation of dental calculus.

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.

Drug repurposing (a.k.a. drug repositioning) is the search for new indications or molecular targets distinct from a drug's putative activity, pharmacological effect or binding specificities. With the ever-increasing rates of termination of drugs in clinical trials, drug repositioning has risen as one of the effective solutions against the risk of drug failures. Repositioning finds a way to reverse the grim but real trend that Eroom's law portends for the pharmaceutical and biotech industry, and drug discovery in general. Further, the advent of high-throughput technologies to explore biological systems has enabled the generation of zeta bytes of data and a massive collection of databases that store them. Computational analytics and mining are frequently used as effective tools to explore this byzantine series of biological and biomedical data. However, advanced computational tools are often difficult to understand or use, thereby limiting their accessibility to scientists without a strong computational background. Hence it is of great importance to build user-friendly interfaces to extend the user-base beyond computational scientists, to include life scientists who may have deeper chemical and biological insights. This survey is focused on systematically presenting the available Web-based tools that aid in repositioning drugs. © The Author 2017. Published by Oxford University Press. All rights reserved.

2015 marked the 25th anniversary of the commercial use and availability of genetically modified crops. The area of planted biotech crops cultivated globally occupies a cumulative two billion hectares, equivalent to twice the land size of China or the United States. Foods derived from genetically modified plants are widely consumed in many countries and genetically modified soybean protein is extensively used in processed foods throughout the industrialised countries. Genetically modified food technology offers a possible solution to meet current and future challenges in food and medicine. Yet there is a strong undercurrent of anxiety that genetically modified foods are unsafe for human consumption, sometimes fuelled by criticisms based on little or no firm evidence. This has resulted in some countries turning away food destined for famine relief because of the perceived health risks of genetically modified foods. The major concerns include their possible allergenicity and toxicity despite the vigorous testing of genetically modified foods prior to marketing approval. It is imperative that scientists engage the public in a constructive evidence-based dialogue to address these concerns. At the same time, improved validated ways to test the safety of new foods should be developed. A post-launch strategy should be established routinely to allay concerns. Mandatory labelling of genetically modified ingredients should be adopted for the sake of transparency. Such ingredient listing and information facilitate tracing and recall if required.

Full Text Available Targeted therapy has made a significant breakthrough for the treatment of different kind of severe diseases, mostly oncological and autoimmune ones. Biological or biotech products, as well as small synthetic molecules, like family of tyrosine kinase inhibitors, have already expressed their efficacy in several important indications. Their availability on the market and reimbursement possibility is of great importance, especially for the patients needed to be on lifelong therapies. Targeted therapy enhanced progression free and overall survival in many conditions, but also a number of these therapies produced important and severe side effects. Considering the fact that targeted therapy is on the global market relatively shortly, there is necessity for prolonged therapy monitoring: for further effectiveness assessment, for safety profile and long term health consequences establishment. Reimbursed targeted therapy proved its benefits that overweight risks, but still remains extremely high costs problem for its application. For an upper middle income country like Serbia, with significantly lower health care expenditures per capita than in other well developed countries, the availability of this expensive therapy is not yet gratifying.

Filamentous fungi are remarkable organisms naturally specialized in deconstructing plant biomass and this feature has a tremendous potential for biofuel production from renewable sources. The past decades have been marked by a remarkable progress in the genetic engineering of fungi to generate industry-compatible strains needed for some biotech applications. In this sense, progress in this field has been marked by the utilization of high-throughput techniques to gain deep understanding of the molecular machinery controlling the physiology of these organisms, starting thus the Systems Biology era of fungi. Additionally, genetic engineering has been extensively applied to modify wellcharacterized promoters in order to construct new expression systems with enhanced performance under the conditions of interest. In this review, we discuss some aspects related to significant progress in the understating and engineering of fungi for biotechnological applications, with special focus on the construction of synthetic promoters and circuits in organisms relevant for industry. Different engineering approaches are shown, and their potential and limitations for the construction of complex synthetic circuits in these organisms are examined. Finally, we discuss the impact of engineered promoter architecture in the single-cell behavior of the system, an often-neglected relationship with a tremendous impact in the final performance of the process of interest. We expect to provide here some new directions to drive future research directed to the construction of high-performance, engineered fungal strains working as microbial cell factories.

Within the global pharmaceutical and biotech industries, there is significant interest in identifying in vitro screening systems that are more human-relevant-i.e., that offer greater utility in predicting subcellular and cellular physiological responses in humans in vivo-and that thereby allow investigators to reduce the incidence of costly late-stage failures during pharmaceutical clinical trials, as well as to reduce the use of animals in drug testing. Currently incumbent in vitro screening methods, such as culturing human hepatocytes in suspension, while useful, are limited by a lack of long term cellular function. In order to address this limitation, we have established an integrated, microfluidic, in vitro platform that combines the patented HmuREL((R)) microdevice with a hepatic coculture system. In the present report, we use this platform to study clearance and metabolite generation of a battery of molecular entities. The results show that the flow-based coculture system is capable of clearing, with improved resolution and predictive value, compounds with high, medium, and low clearance values. In addition, when coculture is coupled with flow, higher metabolite production rates are obtained than in static systems. Copyright 2009 Elsevier Inc. All rights reserved.

Full Text Available In contrast to the dominant drug paradigm in which compounds were developed to fit all, new models focused around personalized medicine are appearing where treatments are customized for individual patients. The agricultural biotechnology industry should also think about these new personalized models. For example, most common herbicides are generic in action, which led to the development of genetically modified crops to add specificity. The ease and accessibility of modern genomic analysis should facilitate the discovery of chemicals that are more selective in their utility. Is it possible to develop species-selective herbicides and growth regulators? More generally put, is plant research at a stage where chemicals can be developed that streamline plant development and growth to various environments? We believe the advent of chemical genomics now opens up these and other opportunities to personalize agriculture. Furthermore, chemical genomics does not necessarily require genetically tractable plant models, which in principle should allow quick translation to practical applications. For this to happen, however, will require collaboration between the Ag-biotech industry and academic labs for early-stage research and development.

Vitamin B6 is a designation for the vitamers pyridoxine, pyridoxal, pyridoxamine, and their respective 5'-phosphates. Pyridoxal 5'-phosphate, the biologically most-important vitamer, serves as a cofactor for many enzymes, mainly active in amino acid metabolism. While microorganisms and plants are capable of synthesizing vitamin B6, other organisms have to ingest it. The vitamer pyridoxine, which is used as a dietary supplement for animals and humans is commercially produced by chemical processes. The development of potentially more cost-effective and more sustainable fermentation processes for pyridoxine production is of interest for the biotech industry. We describe the generation and characterization of a Bacillus subtilis pyridoxine production strain overexpressing five genes of a non-native deoxyxylulose 5'-phosphate-dependent vitamin B6 pathway. The genes, derived from Escherichia coli and Sinorhizobium meliloti, were assembled to two expression cassettes and introduced into the B. subtilis chromosome. in vivo complementation assays revealed that the enzymes of this pathway were functionally expressed and active. The resulting strain produced 14mg/l pyridoxine in a small-scale production assay. By optimizing the growth conditions and co-feeding of 4-hydroxy-threonine and deoxyxylulose the productivity was increased to 54mg/l. Although relative protein quantification revealed bottlenecks in the heterologous pathway that remain to be eliminated, the final strain provides a promising basis to further enhance the production of pyridoxine using B. subtilis.

The osseointegration between the implant and its' bone environment is very important. The implants shall meet the following requirements: biocompatibility, rigidity, resistance against corrosion and technical producibility. In our present study surface morphology and material characteristics of different implants (Denti Bone Level, Denti Zirconium C, Bionika CorticaL, Straumann SLA, Straumann SLA Active, Dentsply Ankylos and Biotech Kontact implant) were investigated with scanning electron microscopy and energy-dispersive X-ray spectroscopy. The possible surface alterations caused by the manufacturing technology were also investigated. During grit-blasting the implants' surface is blasted with hard ceramic particles (titanium oxide, alumina, calcium phosphate). Properties of blasting material are critical because the osseointegration of dental implants should not be hampered. The physical and chemical features of blasting particles could importantly affect the produced surfaces of implants. Titanium surfaces with micro pits are created after immersion in mixtures of strong acids. On surfaces after dual acid-etching procedures the crosslinking between fibrin and osteogenetic cells could be enhanced therefore bone formation could be directly facilitated on the surface of the implant. Nowadays there are a number of surface modification techniques available. These can be used as a single method or in combination with each other. The effect of the two most commonly used surface modifications (acid-etching and grit-blasting) on different implants are demonstrated in our investigation.

Chlamydial infection is one of the most common bacterial sexually transmitted diseases. The aim of the study was to compare Real Time PCR and Direct Immunofluorescence (DIF) in laboratory diagnostics of Chlamydia trachomatis infection in patients of Department of Dermatology and Venereology in Warsaw. We investigated the urethral, cervical, anal and pharyngeal specimens from 152 patients of Department of Dermatology and Venereology in Warsaw. We used DNA Bact Extra Pure Kit (Euroclone®) to isolate DNA. Real Time PCR DUPLICα® 2nd Generation Detection Real Time Advanced Dual Easy Chlamydia trachomatis Kit (Euroclone®) was performed on termocycler Smart Cycler® Dx. For direct immunofluorescence we used MicroTrack Chlamydia trachomatis Direct Specimen Test (Trinity Biotech). In 90% of cases of Real Time PCR and DIF were consistent. 9% of samples were DIF negative and PCR positive and 1% were PCR negative and DIF positive. The results of PCR and DIF were identical more often in woman (98%)than in men (84%). In patients after antibiotics treatment the results of the two tests were consistent in 88%. In laboratory diagnostics of C. trachomatis infections the results of the Real Time PCR and DIF were highly consistent although Real Time PCR. was more sensitive than DIF.
Full Text Available The excessive temperature fluctuations during dental implant site preparation may affect the process of bone-implant osseointegration. In the presented studies, we aimed to assess the quality of cooling during the use of 3 different dental implant systems (BEGO®, NEO BIOTECH®, and BIOMET 3i®. The swine rib was chosen as a study model. The preparation of dental implant site was performed with the use of 3 different speeds of rotation (800, 1,200, and 1,500 rpm and three types of cooling: with saline solution at room temperature, with saline solution cooled down to 3°C, and without cooling. A statistically significant difference in temperature fluctuations was observed between BEGO and NEO BIOTECH dental systems when cooling with saline solution at 3°C was used (22.3°C versus 21.8°C. In case of all three evaluated dental implant systems, the highest temperature fluctuations occurred when pilot drills were used for implant site preparation. The critical temperature, defined in the available literature, was exceeded only in case of pilot drills (of all 3 systems used at rotation speed of 1,500 rpm without cooling.

Vital to patient safety is the accurate assessment and minimization of risk for human immunodeficiency virus (HIV), Hepatitis C (HCV), and Hepatitis B (HBV) virus transmission by deceased donor organ and tissue transplantation. The pathogens are tested by serological kits based on enzyme-linked immunosorbent assay (ELISA), chemiluminescence (CLIA) and eletrochemiluminescence (ECLIA) immunoassays. Organ transplantation is a highly successful life-saving treatment in Brazil, but the Brazilian Health Surveillance Agency currently mandates that all deceased organ donors are screened for HIV, HCV and HBV following living donor policies. In this review, six ELISA (Wama ® , Bio-Rad ® , Biomerieux ® , DiaSorin ® , Acon Biotech ® and Biokit ® ), three CLIA (Abbott ® , Siemens ® , Diasorin ® ) and one ECLIA (Roche ® ) were utilized for evaluating the effectiveness of those serological tests for deceased donors in Brazil according to manufacturer's guidelines. NAT for HIV, HCV and HBV can assist with detection of pre-seroconversion for those infections, and only Cobas ® TaqScreen MPX ® test, the Tigris System ® Procleix Ultrio Assay ® and the Bio-Manguinhos ® HIV/HCV/HBV NAT are commercially available. Between all the tests, only the manufacturer Abbott ® and Cobas ® TaqScreen MPX ® test are currently validated for cadaver samples.

Biotech crops are the fastest adopted crop technology in the history of modern agriculture. The commercialisation of GMO is in many countries strictly regulated laying down the need for traceability and labelling. To comply with these legislations, detection methods are needed. To date, GM events have been developed by the introduction of a transgenic insert (i.e., promoter, coding sequence, terminator) into the plant genome and real-time PCR is the detection method of choice. However, new types of genetic elements will be used to construct new GMO and new crops will be transformed. Additionally, the presence of unauthorised GMO in food and feed samples might increase in the near future. To enable enforcement laboratories to continue detecting all GM events and to obtain an idea of the possible presence of unauthorised GMO in a food and feed sample, an intensive screening will become necessary. A pragmatic, cost-effective, and time-saving approach is presented here together with an overview of the evolution of the GMO and the upcoming needs.

Abstract The meeting "Commercialization of Your Regenerative Medicine Research: Lessons from Spin Out Successes" was hosted by the Oxbridge Biotech Roundtable (OBR) (Oxford, UK) at the University of Oxford in February, 2013, and attracted a multi-stakeholder audience spanning academia and industry. The event featured case studies from Gregg Sando, CEO, Cell Medica (London, UK), John Sinden, CSO, Reneuron (Guilford, UK), and Paul Kemp, CEO and CSO, Intercytex (Manchester, UK). OBR is a student-led initiative with over 7000 members across eight different UK and US locations with a mission to foster a conversation about the healthcare and life sciences industry. Here we review the main themes of the meeting and the major questions facing the regenerative medicine industry and its rapidly emerging subsets of cellular and gene therapies. Notably, we discuss the compatibility of regenerative therapies to the existing healthcare infrastructure, biomanufacturing challenges (including scalability and comparability), and the amenability of regenerative therapies to existing reimbursement and investment models. Furthermore, we reiterate key words of advice from seasoned industry leaders intended to accelerate the translation path from lab bench to the marketplace.
In November 2001, Nature published a letter in which University of California Berkeley's biologists claimed to have found evidence of genetically modified (GM) DNA in regional varieties of maize in Oaxaca, even though the Mexican government had banned transgenic corn agriculture in 1998. While urban protesters marched against the genetic 'contamination' of Mexican corn by US-based agricultural biotech firms, rural indigenous communities needed a framework for understanding concepts such as GM before they could take action. This article analyzes how the indigenous organization, the Zapatistas, mobilized a program to address this novel entity. Their anti-GM project entailed educating local farmers about genetics, importing genetic testing kits, seed-banking landrace corn and sending seeds to 'solidarity growers' around the world. This article explores material-semiotic translations to explain one of the central aspects of this project, the definition and circulation of Zapatista corn--an entity defined not only through cultural geography, but also technological means. Through its circulation, Zapatista corn serves to perform a biocultural engagement with Zapatista's political project of resistance to neoliberalism. While much has been written about both regulatory policy and consumer activism against GM in the Global North, Zapatista corn also provides a case study in indigenous, anti-GM activism founded on biocultural innovation and the creation of alternative networks for circulating corn.

Knowledge of the distribution of ABO-Rh(D) blood groups in a locality is vital for safe blood services. However, the distribution of these blood systems among Ethiopians in general is little explored. This study was, therefore, designed to determine the ABO-Rh(D) blood group distribution among patients attending Gambella hospital, southwestern Ethiopia. A cross-sectional study was conducted between November and December 2013 (N = 449). The patients were grouped into two broad categories. Those who originally moved from different parts of Ethiopia and currently residing in Gambella are named 'highlanders' (n = 211). The other group consisted of natives (Nilotics) to the locality (n = 238). ABO-Rh(D) blood groups were typed by agglutination, open-slide test method, using commercial antisera (Biotech laboratories Ltd, Ipswich, Suffolk, UK). Overall, majority of the participants (41.20%) had blood type 'O' followed by types 'A' (34.96%), 'B' (20.48%) and 'AB' (3.34%). However, blood type 'A' was the most frequent (44.07%) blood group among the 'highlanders' and 50.42% of Nilotic natives had type 'O'. The proportion of participants devoid of the Rh factor was 19.37%. While the ABO blood group distribution is similar to previous reports, the Rh(D) frequency is much higher than what was reported so far for Ethiopia and continental Africa.

The rapid growth of the healthcare industry, and the need to operate more efficiently in this environment, has generated an unmet need for competent business professionals with knowledge of the health care sciences. Additionally, student demand for a business curriculum that would satisfy the needs of the health care industry has provided the impetus for the development of the B.S. Pharmaceutical Health Care and Business program (PHCB). The purpose of this paper is to illustrate the evolution of this innovative curriculum within a school of Pharmacy, and to assess student satisfaction with the current PHCB program. To that end, a 19-item online questionnaire was developed and a group of 56 graduates (2007-2009) were surveyed which resulted in a response rate of 80%. The findings of this study indicated there was an overall high level of student satisfaction with this curriculum with an average of 86%, and that the PHCB program may offer potential to prepare graduates for the business and managerial aspects in the pharmaceutical, biotech, medical device, hospital and other allied health care segments.

Between just 1995 and 2003, the number of new chemical entities fell from 45 to 25, while the costs increased by two and a half times in the same period. Firms in the USA accounted for more than half of biotech drugs from 1982 to 2003. European firms are losing competitiveness. In this hostile environment for investment in pharmaceutical R&D, providing quick access to market for real innovations is the main challenge for regulatory agencies. More initiatives, more entrepreneurial spirit and easier work regulation are needed to facilitate the growth of firms in this field, especially in emerging economies like the Spanish. A new open source model proposes the use of pre-competitive public platforms formed by young and qualified human capital carrying out research in areas not sufficiently attractive for private initiatives, followed by the introduction of pharmaceutical companies to carry out the clinical research. The last step would be fast and effective approval by assessment agencies. Governments should, therefore, facilitate the regulation of socially effective innovations, bringing in manufacturers to take part in the post-clinical trial period after entering the market. The gathering of incentives between regulatory agencies and pharmaceutical industry must be approached through innovation and authorization stimulating systems.

From last decades, intensive research in the field of stem cells proliferation had been promoted due to the unique property of stem cells to self-renew themselves into multiples and has potential to replicate into an organ or tissues and so it's highly demanding though challenging. Bioreactor, a mechanical device, works as a womb for stem cell proliferation by providing nutritious environment for the proper growth of stem cells. Various factors affecting stem cells growth are the bioreactor mechanism, feeding of continuous nutrients, healthy environment, etc., but it always remains a challenge for controlling biological parameters. The present paper unveils the design of mechanical device commonly known as bioreactor in tissues engineering and biotech field, use for proliferation of stem cells and imparts the proper growing condition for stem cells. This high functional bioreactor provides automation mixing of cell culture and stem cells. This design operates in conjunction with mechanism of reciprocating motion. Compare to commercial bioreactors, this proposed design is more convenient, easy to operate and less maintenance is required as bioreactor culture bag is made of polyethylene which is single use purpose. Development of this bioengineering system will be beneficial for better growth and expansion of stem cell

However, new types of genetic elements will be used to construct new GMO and new crops will be transformed. Additionally, the presence of unauthorised GMO in food and feed samples might increase in the near future. To enable enforcement laboratories to continue detecting all GM events and to obtain an idea of the possible presence of unauthorised GMO in a food and feed sample, an intensive screening will become necessary. A pragmatic, cost-effective, and time-saving approach is presented here together with an overview of the evolution of the GMO and the upcoming needs. PMID:23193359

Multitask deep learning has emerged as a powerful tool for computational drug discovery. However, despite a number of preliminary studies, multitask deep networks have yet to be widely deployed in the pharmaceutical and biotech industries. This lack of acceptance stems from both software difficulties and lack of understanding of the robustness of multitask deep networks. Our work aims to resolve both of these barriers to adoption. We introduce a high-quality open-source implementation of multitask deep networks as part of the DeepChem open-source platform. Our implementation enables simple python scripts to construct, fit, and evaluate sophisticated deep models. We use our implementation to analyze the performance of multitask deep networks and related deep models on four collections of pharmaceutical data (three of which have not previously been analyzed in the literature). We split these data sets into train/valid/test using time and neighbor splits to test multitask deep learning performance under challenging conditions. Our results demonstrate that multitask deep networks are surprisingly robust and can offer strong improvement over random forests. Our analysis and open-source implementation in DeepChem provide an argument that multitask deep networks are ready for widespread use in commercial drug discovery.

A mutation breeding is to use physical or chemical mutagens to induce mutagenesis, followed by individual selections with favorable traits. The mutation breeding has many advantages over other breeding methods, which include the usefulness for improving one or two inferior characteristics, applications to broad species with different reproductive systems or to diverse plant materials, native or plant introduction with narrow genetic background, time and cost-effectiveness, and valuable mutant resources for genomic researches. Recent applications of the radiation breeding techniques to developments of flowering plants or food crops with improved functional constituents heightened the public's interests in agriculture and in our genetic resources and seed industries. The goals of this project, therefore, include achieving advances in domestic seed industries and agricultural productivities by developing and using new radiation mutants with favored traits, protecting an intellectual property right of domestic seeds or germplasm, and sharing the valuable mutants and mutated gene information for the genomic and biotech researches that eventually leads to economic benefits.

The aims of the present study were: (i) Evaluate specificity and sensitivity of Hb Smart enzyme-linked immunosorbent assay (ELISA) (ScheBo Biotech) compared to colonoscopy results and (ii) assess stability of a new sample collection device containing a newly formulated buffer to extract haemoglobin using buffer and stool samples spiked with defined concentrations of haemoglobin. Stool samples were quantified with the ELISA method. The stability of haemoglobin in the extraction buffer and in native stool samples, respectively, was determined daily by ELISA during storage for 5 days at 4°C and at room temperature after addition of haemoglobin. Haemoglobin ELISA had a sensitivity of 78.4% for detection of CRC with a specificity of 98%. Haemoglobin extracted in corresponding extraction buffer demonstrated stability throughout storage for 5 days at 4°C and at room temperature. Hb Smart represents a very promising tool for large-scale screening of CRC with regard to sample handling, stability and analysis of haemoglobin in faeces.

Biotherapeutics have become the focus of the pharmaceutical industry due to their proven effectiveness in managing complex diseases. Downstream processes of these molecules consist of several orthogonal, high resolution unit operations designed so as to be able to separate variants having very similar physicochemical properties. Typical process development involves optimization of the individual unit operations based on Quality by Design principles in order to define the design space within which the process can deliver product that meets the predefined specifications. However, limited efforts are dedicated to understanding the interactions between the unit operations. This paper aims to showcase the importance of understanding these interactions and thereby arrive at operating conditions that are optimal for the overall process. It is demonstrated that these are not necessarily same as those obtained from optimization of the individual unit operations. Purification of Granulocyte Colony Stimulating Factor (G-CSF), a biotherapeutic expressed in E. coli., has been used as a case study. It is evident that the suggested approach results in not only higher yield (91.5 vs. 86.4) but also improved product quality (% RP-HPLC purity of 98.3 vs. 97.5) and process robustness. We think that this paper is very relevant to the present times when the biotech industry is in the midst of implementing Quality by Design towards process development. © 2015 American Institute of Chemical Engineers Biotechnol.

The elucidation of the CRISPR (clustered, regularly interspaced, short palindromic repeats) adaptive immune system endogenous to most microbial life has culminated in progress in a diversity of scientific disciplines. The concurrently promising and eccentric nature of its theoretically plausible applications has wrought enthusiasm in the research community globally, potentiating advancements in human and animal health, ecological stability, and economic wellbeing, that would hitherto be considered the unattainable fancies of a futurist. It may be supposed that the tomes of science fiction are the true books of prophecy. Here, we narrate the scientific dialogue regarding CRISPR/Cas biotechnologies, from the happenstantial initial observation of the locus to the litany of intriguing contemporary endeavors. We discuss the mechanistic underpinnings in detail, and the corpulent body of literature on CRISPR-based biotech is digested into a germane and informative review. CRISPR applications such as microbiome engineering in order to enhance the human immune system beyond the fortitude of the wild type, bacterial genome editing in industrial and medical aspects, conquering antibiotic resistance, the development of novel antimicrobial techniques, the harvesting of solventogenic microbes, the development of antifungal therapies, and investigation of the genetic properties of fungi, are here represented, and the authors posit unconventional, and at times gainfully tangential, thoughts and concepts in order to encourage a reflective disposition towards this sophisticated device of nature: a panacea in progress, such that the most impassive and technical writing still carries the ring of poetry.

Full Text Available Breast milk (BM is considered as a reference for infant nutrition. The role of bioactive components, such as cytokines, hormones, growth factors (GFs and fatty acids (FAs is poorly known, but they might be implicated in immune response development. The aim of this study was to identify the lipid profile and the spectrum of cytokines and neuronal GF in BM samples and analyse the influence of gestational age and lactation time on these components. This study used a longitudinal prospective method for the characterization of cytokines, FAs and GFs global profiles in 120 BM samples from 40 healthy mothers (20 preterm and 20 term collected as colostrum, transitional and mature milk. The cytokines were analysed by protein array (Ray Bio® Human Cytokine Array G6. Ray Biotech, Inc. Norcross, GA, USA and the FAs were analysed by gas chromatography. The FA profile was similar between the term and the preterm BM samples. Omega-3-α-linoleic and docosahexaenoic acid (DHA and omega-6-linoleic acid were the most abundant in the term and preterm samples during lactation. Omega-3 ETA and omega-3 EPA we observed exclusively in the preterm samples. The cytokine profile showed a different trend based on gestational age. A significantly higher expression of neurotrophic factors was found in the mature preterm milk samples as compared to the mature term samples. Our study is the first to identify the influence and interactions of perinatal factors on cytokine, GFs and FAs in human milk.

Small companies working to develop products in the cardiovascular space face numerous challenges, from regulatory, intellectual property, and reimbursement barriers to securing funds to keep the lights on and reach the next development milestone. Most small companies that spin out from universities have the scientific knowledge, but product development expertise and business acumen are also needed to be successful. Other challenges include reduced interest in early stage technologies (Pharma & Biotech 2015 in Review, EP Vantage) and limited deal flow for cardiovascular products (Gormley B., Wall Street Journal, September 15, 2014). The NHLBI small business program is a comprehensive ecosystem designed to address these critical challenges and to provide resources and expertise to assist early stage companies developing cardiovascular and other products within the institute's mission. This article describes steps that NHLBI has taken to enhance our small business program to more effectively translate basic discoveries into commercial products to benefit patients and public health, including enhancing internal expertise and developing non-financial resources to assist small businesses as they develop their products and seek private sector investment and partnership.

Despite of growing oncology pipeline, cancer vaccines contribute only to a minor share of total oncology-attributed revenues. This is mainly because of a limited number of approved products and limited sales from products approved under compassionate or via early access entry in smaller and less developed markets. However revenue contribution from these products is extremely limited and it remains to be established whether developers are breaking even or achieving profitability with existing sales. Cancer vaccine field is well recognized for high development costs and risks, low historical rates of investment return and high probability of failures arising in ventures, partnerships and alliances. The cost of reimbursement for new oncology agents is not universally acceptable to payers limiting the potential for a global expansion, market access and reducing probability of commercial success. In addition, the innovation in cancer immunotherapy is currently focused in small and mid-size biotech companies and academic institutions struggling for investment. Existing R&D innovation models are deemed unsustainable in current "value-for-money" oriented healthcare environment. New business models should be much more open to collaborative, networked and federated styles, which could help to outreach global, markets and increase cost-efficiencies across an entire value chain. Lessons learned from some developing countries and especially from South Korea illustrate that further growth of cancer vaccine industry will depends not only on new business models but also will heavily rely on regional support and initiatives from different bodies, such as governments, payers and regulatory bodies.

The patentability of human genes was from the beginning of the discussion concerning the Directive on the legal protection of biotechnological inventions, an issue that provoked debates among politicians, scientists, lawyers and civil society itself. Although Directive 98/44 tried to settle the matter by stating that to support the patentability of human genes, it should know what role they fulfill, which protein they encode, all of this as an essential requirement to test its industrial application. However, following the judgment of 13 June 2013 (Supreme Court of the United States of America in the case of Association for Molecular Pathology et al. versus Myriad Genetics Inc.) the debate on this issue has been reopened. There are several issues to be considered, taking into account that the patents on DNA & Gene Sequences have played an important incentive to increase the interest in biotechnology applied to human health. On the other hand, this is a paradigm shift in the R & D of biopharmaceutical companies, and it has moved from an in house research model to a model of open innovation, a model of collaboration between large corporations with biotech SMEs and public and private research centers. This model of innovation, impacts on the issue of the industrial property, and therefore it will be necessary to clearly define what each party brings to the relationship and how they are expected to share the results. But all of this, with the ultimate goal that the patients have access to treatments and medications most innovative, safe and effective.

Full Text Available Brazil is renowned for its biodiversity; however, its economy is based on exotic plants, extraction and unsustainable use of natural resources. This issue was addressed in a recent QN review entitled "Chemistry without Borders." In order to explore the potential of Brazilian biodiversity fully, sustainable development is required in key technological areas, such as biotechnology. This research field is consistent with the green chemistry and white technology principles. Therefore, biotechnology is a sustainable alternative to conventional technologies and is expected to account for 20% of global chemicals by 2020. Brazil is the second largest grower of biotech crops and biodiesel, but its main activities rely on the fermentative process. In order to stimulate the national biotechnology development, the Brazilian Federal Government launched a national policy for biotechnology in 2007 and the National Committee of Biotechnology was created. Among the outstanding biotechnological processes, biocatalysis is one of the most important alternatives to conventional processing, and this field has changed dramatically with the advent of recombinant DNA technology in the 1970s, when large quantities of enzymes were accessible. The direct evolution methodology in the 1990s was a breakthrough and allowed tailoring of enzymes possessing high stability and stereoselectivity. However, about 60 years after the first industrial enzymatic biotransformation of steroids, the full potential of biocatalysis is far from being achieved. Future challenges in this field concern the multienzyme cascade reactions associated with optimized chemoenzymatic processes, and some recent industrial application of biocatalysts are also highlighted in this perspective.

Manufacturing high-value added biotech biopharmaceutical products (e.g. therapeutic proteins) requires quick-to-develop, GMP-compliant, easy-to-scale and cost effective preparatory chromatography technologies. In this work, we describe the construction and testing of a set of 5-mm inner diameter stainless steel toroidal columns for use on commercially available preparatory scale synchronous J-type counter-current chromatography (CCC) machinery. We used a 20.2m long column with an aqueous two-phase system containing 14% (w/w) PEG1000 and 14% (w/w) potassium phosphate at pH 7, and tested a sample loading of 5% column volume and a mobile phase flow rate of 20ml/min. We then satisfactorily demonstrated the potential for a weekly protein separation and preparation throughput of ca. 11g based on a normal weekly routine for separating a pair of model proteins by making five stacked injections on a single portion of stationary phase with no stripping. Compared to our previous 1.6mm bore PTFE toroidal column, the present columns enlarged the nominal column processing throughput by nearly 10. For an ideal model protein injection modality, we observed a scaling up factor of at least 21. The 2 scales of protein separation and purification steps were realized on the same commercial CCC device. Copyright © 2015 Elsevier B.V. All rights reserved.

The paper presents the results of studying the role of interleukins 4 and 6 in the pathogenesis of periodontal tissue diseases, specifically, in periodontitis, gingivitis and alveolitis. To study the nature of participation of IL-4 and IL-6 in the mechanisms of development of periodontitis, gingivitis and alveolitis. Studies were carried out on 80 nonlinear male rats with a body weight of 200.0 to 220.0 g divided into four groups of 20 animals each. The serum level of cytokines was determined by an enzyme immunoassay on the Multiscane Biotech analyzer using test systems manufactured by Caltag laboratories (USA). Statistical processing of the obtained digital results was processed with the help of the program "Statistica 8.0". Indicators of the reliability of changes between the control and intact groups also used the Student's test and the Excel program. The confidence level was taken at p gingivitis, where it decreased by 74% and its level became less with alveolitis and periodontitis, since in these diseases the level of IL-6 was practically the same from the control (p gingivitis, on the contrary, indicates the realization of a pathological reaction of the organism. The change in the levels of pro- and anti-inflammatory interleukins, especially with gingivitis, indicates a decrease in the body's adaptive reserves and may affect the further dynamics of the inflammatory process in the periodontal tissues.

There is evidence that the polymorphisms of the genes involved in folate metabolism may be associated with higher risk of Down syndrome (DS) pregnancy. The aim of the present study was to investigate the effect of A80G polymorphism in reduced folate carrier 1 (RFC1) gene on the maternal risk for DS. In our study, twenty-two DS mothers and forty-two mothers who had no children with DS were evaluated. Genomic DNA was isolated from whole peripheral blood collected on EDTA, using peqGOLD blood DNA mini kit (ATP Biotech) following the manufacturer's instructions. The results show that the frequencies of RFC1 alleles, as well as the frequencies of RFC1 A80G genotypes (GG, GA, AA, GA+AA) do not correlate with DS pregnancies, demonstrating no difference between the case and control groups. In the present study, we did not find any statistically significant association between RFC-1 polymorphic genotype and history of DS pregnancies; thus, the relationship between RFC-1 polymorphism and DS appears to be only a supposition and the next step in our study is the catamnestic evaluation of our patients with DS babies for two years.

Hepatocellular carcinoma (HCC) is a big problem in China where the Hepatitis B (HBV) infection patients are near to 120 million. Early screening and diagnosis is the key to reduce the incidence and mortality of HCC. Serum AFP detection is the main methods for diagnosis, recurrent monitoring and therapeutic evaluation of primary HCC. Hepatitis patients should detect the AFP at least once every six months to help early diagnosis of HCC. Unfortunately, most hepatitis and other liver disease patients do not test their AFP regularly. Therefore, a rapid, convenient detect kit for AFP is necessary for the hepatitis patients to test AFP at home by themselves. It will be very helpful to the HCC early screening and early diagnosis. We screened 859 individuals who were HBsAg positive and had high risk of HCC in Qidong by using two different kits, AFP one-step rapid detection kit (Shanghai Outdo Biotech) and AFP Diagnostics ELISA kit (Zhengzhou Autobio Diagnostics), and compared the results. As a result, the positive accordance rate and the negative accordance rate of AFP one-step rapid detection kit and the Autobio ELISA kit were 95.65% (22/23) and 99.40% (831/836), respectively. The total diagnose accordance rate reached up to 99.30% (853/859). The screening results showed a high accordance rate of two methods. It is so meaningful to achieve home-test and improve HCC early screening and diagnosis by using AFP one-step rapid detection kit.
This new bestseller from leading economist Mariana Mazzucato – named by the ‘New Republic’ as one of the ‘most important innovation thinkers’ today – is stirring up much-needed debates worldwide about the role of the State in innovation. Debunking the myth of a laggard State at odds with a dynamic private sector, Mazzucato reveals in case study after case study that in fact the opposite situation is true, with the private sector only finding the courage to invest after the entrepreneurial State has made the high-risk investments. Case studies include examples of the State’s role in the ‘green revolution’, in biotech and pharmaceuticals, as well as several detailed examples from Silicon Valley. In an intensely researched chapter, she reveals that every technology that makes the iPhone so ‘smart’ was government funded: the Internet, GPS, its touch-screen display and the voice-activated Siri. Mazzucato also controversially argues that in the history of modern capitalism the State has not on...

Soybean is one of the most important biotech crops, widely used as an ingredient in both foodstuffs and feed. DNA extraction methods have been evaluated to detect the presence of genetically modified (GM) materials in soya-containing food and feed products commercialised in Turkey. All extraction methods performed well for the majority of soya foods and feed products analysed. However, the most successful method varied between different products; the Foodproof, Genespin and the cetyltrimethylammonium bromide (CTAB) methods each produced the highest DNA yield and purity for different soya foodstuffs and feeds. Of the samples tested, 20% were positive for the presence of at least two GM elements (35S/NOS) while 11% contained an additional GM element (35S/NOS/FMV). Of the tested products, animal feeds showed a larger prevalence of GM material (50%) than the soya-containing foodstuffs (13%). The best performing extraction methods proved to be the Foodproof, Genespin and CTAB methods for soya-containing food and feed products. The results obtained herein clearly demonstrate the presence of GM soybean in the Turkish market, and that the Foodproof GMO Screening Kit provides reliable screening of soy-containing food and feed products. © 2014 Society of Chemical Industry.

Rapid HIV antibody tests are commonly used for HIV diagnosis in the developing world. These tests are generally reported as sensitive, despite paucity of evaluations in paediatric populations. We tested specimens of paediatric patients, known to be HIV-infected, to detect any false negative tests and determine associations with such an outcome. One hundred and fifty-three specimens, from 109 patients, recorded to be HIV-infected by standard testing, were tested on the Capillustrade mark HIV-1/HIV-2 test (Trinity Biotech, Ireland); 150 specimens also had sufficient volume to be tested on Abbott Determinetrade mark HIV1/2 assay (Abbott GmbH, Wiesbaden, Germany). Treatment information, CD4 counts and HIV-1 viral load measurements were obtained from patient files and laboratory databases. Twenty-one of 153 specimens tested negative on the Capillus (sensitivity 86.3%). False negative results by Capillus were associated with antiretroviral treatment (ART) (p=0.0018) and lower HIV-1 viral load (p=0.013). Serial dilutions of some of the specimens indicated that both rapid tests, and the Capillus in particular, became negative at lower dilutions than an HIV enzyme immunoassay (EIA). The Capillus test had an unexpectedly low sensitivity in a South African population of HIV-infected children that had access to antiretroviral treatment, posing a risk of false negative HIV testing.
The World Vaccine Congress Washington 2009 was held in Chantilly, VA USA April 2O -23rd. The Vaccine congress attracted over 400 participants from across the world, including leading vaccine manufacturers, biotechs, governmental agencies, NGOs, research and academic institutes, venture capital and legal firms, contract service and equipment manufacturers. The speakers covered a wide range of topics, including the role of government and regulatory agencies, funding availability, research and development, manufacturing, packaging and post vaccine evaluations. Past vaccine development efforts have historically focused on infectious diseases. With advancements in the field of immunology, molecular biology and vaccinology, the vaccine field has begun moving in new directions. "Taking aim at novel vaccines market" session chaired by Dr. Una Ryan, Chief Executive Officer of Waltham Technologies, was focused on traditional approaches to novel targets (nosocomial infections), novel approaches to traditional targets (flu and rabies), novel approaches to novel targets (Type 1 diabetes, multiple sclerosis and smoking) and vaccines for developing markets (TB, malaria, rabies). The importance of collaborations among academic institutions, industries, and philanthropic foundations for developing markets was also emphasized.

The 5-HT 2C R agonist lorcaserin, clinically approved for the treatment of obesity, causes important side effects mainly related to subtype selectivity. In the search for 5-HT 2C R allosteric modulators as safer antiobesity drugs, a chemical library from Vivia Biotech was screened using ExviTech platform. Structural modifications of identified hit VA240 in synthesized analogues 6-41 afforded compound 11 (N-[(1-benzyl-1H-indol-3-yl)methyl]pyridin-3-amine, VA012), which exhibited dose-dependent enhancement of serotonin efficacy, no significant off-target activities, and low binding competition with serotonin or other orthosteric ligands. PAM 11 was very active in feeding inhibition in rodents, an effect that was not related to the activation of 5-HT 2A R. A combination of 11 with the SSRI sertraline increased the anorectic effect. Subchronic administration of 11 reduced food intake and body weight gain without causing CNS-related malaise. The behavior of compound 11 identified in this work supports the interest of a serotonin 5-HT 2C R PAM as a promising therapeutic approach for obesity.

Leading European nations with strong biotech sectors, such as the UK and Germany, are investing heavily in regenerative medicine, seeking competitive advantage in this emerging sector. However, in the broader biopharmaceutical sector, the EU is outperformed by the USA on all metrics, reflecting longstanding problems: limited venture capital finance, a fragmented patent system, and relatively weak relations between academia and industry. The current global downturn has exacerbated these difficulties. The crisis comes at a time when the EU is reframing its approach to the governance of innovation and renewing its commitment to the goal of making Europe the leading player in the global knowledge economy. If the EU is to gain a competitive advantage in the regenerative medicine sector then it must coordinate a complex multilevel governance framework that encompasses the EU, member states and regional authorities. This article takes stock of Europe's current competitive position within the global bioeconomy, drawing on a variety of metrics in the three intersecting spheres of innovation governance: science, market and society. These data then provide a platform for reviewing the problems of innovation governance faced by the EU and the strategic choices that have to be confronted in the regenerative medicine sector.

Like nuclear energy, most technologies could have dual use-for health and well being and disaster and terror. Some research publications have brought to the forefront the tragic consequences of the latter potential through their possible use. Monitoring life science research and development (R&D) to prevent possible misuse is a challenging task globally, more so in developing economies like India, which are emerging as major biotech hubs. As a signatory to the Biological and Toxin Weapons Convention, India has put in motion a process of evolving a series of measures to manage dual-use technology. The Indian Council of Medical Research (ICMR) has taken a lead in drafting model codes of conduct, ethics and practice for use by other S&T agencies to tailor them as per their requirements. Taking cue from the discussions held by the editors of the various medical and science journals in the developed world, the Indian Journal of Medical Research, the official publication of the ICMR, is working on policy and uniform practice of publication of dual-use research results. The Government of India too has promulgated legal provisions to minimize the risks of misuse of technology, like the Weapons of Mass Destruction Act. Clearly, no single agency would be able to manage the dual-use of technology effectively. Multiple agencies have to come together to work in tandem for effective implementation of various measure and also like Janus, ensure that they are neither too restrictive nor intrusive to discourage the development of science.

Novalux Inc was an enterprise founded by Aram Mooradian in 1998 to commercialise a novel electrically pumped vertical extended cavity semiconductor laser platform, initially aiming to produce pump lasers for optical fiber telecommunication networks. Following successful major investment in 2000, the company developed a range of single- and multi-mode 980 nm pump lasers emitting from 100-500 mW with excellent beam quality and efficiency. This rapid development required solution of several significant problems in chip and external cavity design, substrate and DBR mirror optimization, thermal engineering and mode selection. Output coupling to single mode fiber was exceptional. Following the collapse of the long haul telecom market in late 2001, a major reorientation of effort was undertaken, initially to develop compact 60-100 mW hybrid monolithically integrated pumplets for metro/local amplified networks, then to frequency-doubled blue light emitters for biotech, reprographics and general scientific applications. During 2001-3 I worked at Novalux on a career break from University College Cork, first as R&D Director managing a small group tasked with producing new capabilities and product options based on the NECSEL platform, including high power, pulsed and frequency doubled versions, then in 2002 as Director of New Product Realization managing the full engineering team, leading the transition to frequency doubled products.

The Human Protein Atlas (HPA) enables the simultaneous characterization of thousands of proteins across various tissues to pinpoint their spatial location in the human body. This has been achieved through transcriptomics and high-throughput immunohistochemistry-based approaches, where over 40 000 unique human protein fragments have been expressed in E. coli. These datasets enable quantitative tracking of entire cellular proteomes and present new avenues for understanding molecular-level properties influencing expression and solubility. Combining computational biology and machine learning identifies protein properties that hinder the HPA high-throughput antibody production pipeline. We predict protein expression and solubility with accuracies of 70% and 80%, respectively, based on a subset of key properties (aromaticity, hydropathy and isoelectric point). We guide the selection of protein fragments based on these characteristics to optimize high-throughput experimentation. We present the machine learning workflow as a series of IPython notebooks hosted on GitHub (https://github.com/SBRG/Protein_ML). The workflow can be used as a template for analysis of further expression and solubility datasets. email@example.com or firstname.lastname@example.org.

Bacterial surface display is an attractive technique for the production of cell-anchored, functional proteins and engineering of whole-cell catalysts. Although various outer membrane proteins have been used for surface display, an easy and versatile high-throughput-compatible assay for evaluating and developing surface display systems is missing. Using a single domain antibody (also called nanobody) with high affinity for green fluorescent protein (GFP), we constructed a system that allows for fast, fluorescence-based detection of displayed proteins. The outer membrane hybrid protein LppOmpA and the autotransporter C-IgAP exposed the nanobody on the surface of Escherichia coli with very different efficiency. Both anchors were capable of functionally displaying the enzyme Chitinase A as a fusion with the nanobody, and this considerably increased expression levels compared to displaying the nanobody alone. We used flow cytometry to analyse display capability on single-cell versus population level and found that the signal peptide of the anchor has great effect on display efficiency. We have developed an inexpensive and easy read-out assay for surface display using nanobody:GFP interactions. The assay is compatible with the most common fluorescence detection methods, including multi-well plate whole-cell fluorescence detection, SDS-PAGE in-gel fluorescence, microscopy and flow cytometry. We anticipate that the platform will facilitate future in-depth studies on the mechanism of protein transport to the surface of living cells, as well as the optimisation of applications in industrial biotech.
Full Text Available Raising of alpacas as exotic livestock for wool and meat production and as companion animals is growing in importance in the United States, Europe and Australia. Furthermore the alpaca, as well as the rest of the camelids, possesses the peculiarity of producing single-chain antibodies from which nanobodies can be generated. Nanobodies, due to their structural simplicity and reduced size, are very versatile in terms of manipulation and bio-therapeutic exploitation. In fact the biotech companies involved in nanobody production and application continue to grow in number and size. Hence, the development of reagents and tools to assist in the further growth of this new scientific and entrepreneurial reality is becoming a necessity. These are needed mainly to address alpaca disease diagnosis and prophylaxis, and to develop alpaca immunization strategies for nanobody generation. For instance an immortalized alpaca cell line would be extremely valuable. In the present work the first stabilized alpaca cell line from alpaca skin stromal cells (ASSCs was generated and characterized. This cell line was shown to be suitable for replication of viruses bovine herpesvirus-1, bovine viral diarrhea virus and caprine herpesvirus-1 and the endocellular parasite Neospora caninum. Moreover ASSCs were easy to transfect and transduce by several methods. These two latter characteristics are extremely useful when recombinant antigens need to be produced in a host homologous system. This work could be considered as a starting point for the expansion of the biotechnologies linked to alpaca farming and industry.
A rapid growth of investment into clinical research and new drug development has manifested itself by an exponential increase of new products coming onto the worldwide market. The emerging pharmaceutical and biotech markets in Southeast Asia are believed to be extremely promising from a commercial point of view in the next decade. The unique position of the Asian market and the diversity in clinical research initiatives are linked with diverse regulatory requirements for clinical development and registration of new medicines. Some of these differences have an impact on timelines for marketing authorizations in South Korea, China, Thailand, Japan, Singapore, and other countries. One of the approaches to streamlining regulatory strategy in different countries is the initiation of multicountry international clinical trials trying to address requirements and allowing registration in several regional countries simultaneously. Increasing cooperation between South Asian countries in relation to regulatory requirements and clinical development will facilitate the registration of innovative medicines in this rapidly developing region of the world and enable improved cohesiveness between countries in a drug safety framework.
Recent criticisms of traditional understandings of risk, responsibility and the division of labour between science and politics build on the idea of the co-produced character of the natural and social orders, making a case for less ambitious and more inclusive policy processes, where questions of values and goals may be addressed together with questions of facts and means, causal liabilities and principled responsibilities. Within the neo-liberal political economy, however, the contingency of the world is depicted as a source of unprecedented opportunities for human craftsmanship, rather than of possibly unmanageable surprises. Gene technologies offer a vantage point for reflecting on the consequences of the drift from discovery to invention as a master frame in the appraisal of human intermingling with the world. Biotech patenting regulations carve out a sovereign agency which, by crafting nature, also crafts the distinction between the manufactured and non-manufactured world. Difficulties in ascribing responsibility stem as a consequence. It is likely that politics and economy can be democratized and responsibilities rearranged not by 'democratizing' knowledge production, but rather the reverse.

Concerns have been voiced about the ethical implications of patenting practices in the field of biotechnology. Some of these have also been incorporated into regulation, such as the European Commission Directive 98/44 on the legal protection of biotechnological inventions. However, the incorporation of ethically based restrictions into patent legislation has not had the effect of satisfying all concerns. In this article, we will systematically compare the richness of ethical concerns surrounding biotech patenting, with the limited scope of ethical concerns actually addressed in the patent system. As sources of our analyses we will use literature and document studies and a survey with important stakeholders and experts related to Norwegian patenting in the aquacultural biotechnology sector. We will structure the analyses with an ethical matrix, developed for this purpose. Showing the misalignment of the discussions within and outside the patent system, we suggest that an important reason for the ethical controversy still surrounding patenting is that ethical questions keep being framed in a narrow way within the system. Until a richer set of ethical considerations is addressed head-on within the patent system, the patent system will continue to evoke academic and interest group criticism, potentially contributing to a legitimacy crisis of the whole system.

A mutation breeding is to use physical or chemical mutagens to induce mutagenesis, followed by individual selections with favorable traits. The mutation breeding has many advantages over other breeding methods, which include the usefulness for improving one or two inferior characteristics, applications to broad species with different reproductive systems or to diverse plant materials, native or plant introduction with narrow genetic background, time and cost-effectiveness, and valuable mutant resources for genomic researches. Recent applications of the radiation breeding techniques to developments of flowering plants or food crops with improved functional constituents heightened the public's interests in agriculture and in our genetic resources and seed industries. The goals of this project, therefore, include achieving advances in domestic seed industries and agricultural productivities by developing and using new radiation mutants with favored traits, protecting an intellectual property right of domestic seeds or germplasm, and sharing the valuable mutants and mutated gene information for the genomic and biotech researches that eventually leads to economic benefits

Annona Muricata belongs to the family Annonaceae which is known to have anticancer, anti-inflammatory and many other bio activities. Leaves, twig, fruit and seed of A. muricata were collected from Suhan Biotech and dried. Hot and cold aqueous extracts were prepared for the preliminary screening of phytochemicals and aqueous extracts of A. muricata were evaluated for total phenolic, scavenging assay (DPPH; 1-1-diphenyl-2-picrylhydrazyl) and cytotoxic activities. Phytochemicals screening of leaves extracts revealed the presence of alkaloids, terpenoid, reducing sugar, carbohydrate and anthocyanins. While for twig extracts it revealed the presence of coumarine. Antra quinones, terpenoid, flavonoid, reducing sugar, lipids and coumarine were found in fruit and seed extracts. The total phenolic content was found to be 2.372±0.922 μg GAE/ g, 85.85±6.23 μg GAE/ g, 53.56±8.39 μg GAE/ g and 54.67±13.33 μg GAE/ g for leaves, twig, fruit and seed respectively. On the other hand, all extract have showed IC 50 value more than 500 μg/ mL in DPPH scavenging assay. Cytotoxic evaluation of all extracts against HTB43, MCF-7 and MDAMB231 cell lines showed IC 50 value more than 250 μg/ mL. In conclusion, the results showed that aqueous extract of A.muricata was inappropriate as anticancer agen (author)

'Biogenerics' regulation has brought about a heated debate within the EU as the first biopharmaceuticals are going off patent. This study aims to examine the opportunities and challenges offered by biogenerics by surveying the viewpoints of experts in regulatory agencies and in companies developing novel biopharmaceuticals and biogenerics. Oral interviews were conducted in 2002 and 2003 with experts including representatives of the European Generic Medicines Association (EGA) and the European Federation of Pharmaceutical Industries and Associations (EFPIA) in Brussels, three innovator biotech companies, and five other experts in Finland. Additionally, four biogenerics companies and one innovator company abroad answered a structured, written questionnaire. According to this study, biogenerics should be regulated on a case-by-case basis. The interviewees were not unanimous as to whether comparability can be addressed and which are the most challenging areas for proving comparability. Immunogenicity was considered to be a major problem for biogenerics. Therefore, a requirement for an intensified monitoring of the safety profile during post-marketing was thought to be justified in many cases.

Abstract The fields of tissue engineering (TE) and regenerative medicine (RegMed) are yet to bring about the anticipated therapeutic revolution. After two decades of extremely high expectations and often disappointing returns both in the medical as well as in the financial arena, this scientific field reflects the sense of a new era and suggests the feeling of making a fresh start although many scientists are probably seeking reorientation. Much of research was industry driven, so that especially in the aftermath of the recent financial meltdown in the last 2 years we have witnessed a biotech asset yard sale. Despite any monetary shortcomings, from a technological point of view there have been great leaps that are yet to find their way to the patient. RegMed is definitely bound to play a major role in our life because it embodies one of the primordial dreams of mankind, such as: everlasting youth, flying, remote communication and setting foot on the moon. The Journal of Cellular and Molecular Medicine has been at the frontier of these developments in TE and RegMed from its beginning and reflects recent scientific advances in both fields. Therefore this review tries to look at RegMed through the keyhole of history which might just be like looking ‘back to the future’. PMID:20825521

The author started a niche biotech company in 1985 called Flexcell ® to distribute an enabling technology, mechanobiology devices, to the field. He was the first University of North Carolina faculty member to start a company and stay with it as he pursued his career in academics. That was an unpopular route at that time, but a path he was driven to navigate. Those interests, merged with his training, led to the design and manufacture of mechanobiology devices such as the Flexercell ® Strain Unit and the BioFlex ® flexible bottom culture plates to study fundamental responses of cells to strain. Principles in these devices were also incorporated into bioreactors for tissue engineering, which are standard in the marketplace today. In this article, the major roadblocks will be chronicled that were overcome to help build the field of mechanobiology and create a small biotechnology company. Through example, the author's formula for achieving milestones will be discussed including, the DRIVE it takes to get there ["DRIVE": Determination (Confidence), Research and Development (R&D) and Risk-Taking, Innovation (Imagination) and Intellectual Property, achieving Victory, and Enterprise].

Chitosan is a natural polysaccharide that has attracted significant scientific interest during the last two decades. It is a potentially biologically compatible material that is chemically versatile (-NH2 groups and various M(w)). These two basic properties have been used by drug delivery and tissue engineering scientists to create a plethora of formulations and scaffolds that show promise in healthcare. Despite the high number of published studies, chitosan is not approved by the FDA for any product in drug delivery, and as a consequence very few biotech companies are using this material. This review will aim to provide information on these biological properties that affect chitosan's safe use in drug delivery. The term "Chitosan" represents a large group of structurally different chemical entities that may show different biodistribution, biodegradation and toxicological profiles. Here we aim to review research in this area and critically discuss chitosan's potential to be used as a generally regarded as safe (GRAS) material. 2009 Elsevier B.V. All rights reserved.

The aim of the study was to evaluate the use of Surgisis (Cook Biotech Inc.), a porcine derived extracellular matrix already used in tissue engineering, as a scaffold for neointestinal regeneration in a rat model. A 3-cm length of tubular Surgisis graft was interposed with bilateral anastomoses in the middle of an isolated ileal loop of Sprague Dawley rats with an ileostomy. The grafts were harvested and analyzed using histology and immunohistochemistry at 24 weeks after operation. Macroscopic examination revealed neither stenosis nor adhesions in the area surrounding the neointestine. The regenerated small bowel showed a mean shrinkage of 30.7% (range 20%-40%). Histologic and immunohistochemical evaluation showed a well-developed three layers of mucosa and smooth muscle and serosa in the regenerated bowel wall that were similar to those of the normal bowel with evident neovascularization. Also, the regeneration of smooth muscle fibers and innervation were evident. The preliminary results of this study showed that Surgisis allowed rapid regeneration of mucosa and smooth muscle and therefore may be a promising material for the creation of a neointestine.

Articular cartilage lesions predispose to the development of early osteoarthritis. Most current surgical techniques give rise to the formation of fibrocartilage with biochemical and biomechanical properties inferior to those or articular cartilage. Tissue engineering could offer a modern alternative to the treatment of these lesions and in this way, prevent the development of early osteoarthritis in young active patients. Different tissue engineering approaches rely on the current use of autologous chondrocytes, or the potential use of mesenchymal stem cells. Other variables rely on the type of scaffold to use such as synthetic biodegradable polymers, fibrin or collagen-derived scaffolds of different sources, bovine, porcine, rat tail, etc, in the form of gels, sponges, mesh, etc, and all of these with or without growth factors. The use of autologous chondrocytes is a reality at the present time, whether injected under a periosteum patch or seeded on collagen. However, most investigators and biotech companies are in search of onestep surgical procedures, for which reason stem cells have to be kept in mind, as well as systems that will allow arthroscopic implantation.

We wanted to determine the technical and clinical efficacy of placing a self-expandable PTFE-covered nitinol stent for the management of inoperable malignant biliary obstruction. Thirty six patients with inoperable malignant biliary obstructions were treated by placement of self-expandable PTFE-covered nitinol stents (S and G Biotech Corporation, Seongnam, Korea). Clinical evaluation was done with assessment of the serum bilirubin and alkaline phosphatase levels, which were measured before and after stent placement within 1 week, at 1 month and at 3 months. The patient survival rate and stent patency rate were calculated with performing Kaplan-Meier survival analysis. Successful stent placement was achieved in all the patients without procedure-related complication. Pancreatitis as an early complication occurred in two cases. The serum bilirubin and alkaline phosphatase levels were significantly decreased after the procedure. During the follow-up, recurrent obstructive jaundice occurred in six cases; stent migration occurred in four cases and tumor overgrowth occurred in two cases. The survival rates were 97%, 80%, 67% and 59% at 1, 3, 6 and 9 months, respectively. The stent patency rates were 96%, 92%, 86% and 86% at 1, 3, 6 and 9 months, respectively. Self-expandable PTFE-covered nitinol stent placement seems to be technically feasible and effective for the palliative treatment of malignant biliary obstruction

Due to changing macro and micro factors, expiring patents and falling net income, pharmaceutical companies need to rethink their vertical business model. The trend shows cross-sectorial partnerships and consolidation to remain and compete on the market. Areas covered: Quantitative research interviewing a target group of 25 key executives from small, mid and large global pharmaceutical companies rounded with qualitative literature research completing the analysis. Expert commentary: Uncertainty in the industry due to changing external factors i.e. pricing pressures, regulations or an economic slowdown, slowing down innovations and new drug outcomes. Pharmaceutical companies understand the existing hurdles, and are critically optimistic implementing new business models. Also, various stakeholders are included in the value chain due to their growing importance. During the next years, the industry will be restructured from volume towards value, and only pharmaceutical companies' clairaudient and reciprocate to the changes with an out-off the box thinking will be able to resist on the market. Small biotech companies should focus on research, and big pharmaceutical companies entering at development focusing on the process until the distribution. This execution business recommendation would enable the best know-how at the right point, mitigating the risk and enhancing the patient outcomes.
