Clonal micropropagation. Methods of cloning by in vitro culture led to the development of a micropropagation technique for oil palm based on somatic embryogenesis which was tested at the pilot stage on elite genotypes, thus enabling the production of high oil yielding clones. This phase allowed the identification of limiting factors associated with scaling-up, with respect in particular to the scale of mass production required to meet the needs of planters and to the problem of ensuring genetic fidelity in the regenerated plant material. These two concerns led researchers to look further into the underlying physiological and/or molecular mechanisms involved in somatic embryogenesis and the somaclonal variation events induced by the in vitro cloning procedure. Structural and functional genomics. Marker-assisted breeding in oil palm is a long-term multi-stage project including: molecular analysis of genetic diversity in both E. guineensis and E. oleifera germplasms; large scale development of PCR-based microsatellite markers; and parallel development of three genome mapping and QTL detection projects studying key agronomic characters. Post-genomics. In order to tackle the problem of the mantled flowering abnormality, which is induced during the micropropagation process, studies of gene expression have been carried out in tissue cultures as a means of establishing an early clonal conformity testing procedure. It is important to assess what kind of methodology is the most appropriate for clonal conformity testing by comparing RNA, protein and DNA (PCR based approaches. Parallel studies on genomic DNA methylation changes induced by tissue culture suggest that the latter may play an important role in the determination of the mantled abnormality.

    Robotic sailing offers the potential of wind propelled vehicles which are sufficiently autonomous to remain at sea for months at a time. These could replace or augment existing oceanographic sampling systems, be used in border surveillance and security or offer a means of carbon neutral transportation. To achieve this represents a complex, multi-disciplinary challenge to boat designers and naval architects, systems/electrical engineers and computer scientists.  Since 2004 a series of competitions in the form of the Sailbot, World Robotic Sailing Championship and Microtransat competitions have sparked an explosion in the number of groups working on autonomous sailing robots. Despite this interest the longest distance sailed autonomously remains only a few hundred miles. Many of the challenges in building truly autonomous sailing robots still remain unsolved. These proceedings present the cutting edge of work in a variety of fields related to robotic sailing. They will be presented during the 5th International...

    For thousands of years, microorganisms have been used to supply products such as bread, beer and wine. A second phase of traditional microbial biotechnology began during World War I and resulted in the development of the acetone-butanol and glycerol fermentations, followed by processes yielding, for example, citric acid, vitamins and antibiotics. In the early 1970s, traditional industrial microbiology was merged with molecular biology to yield more than 40 biopharmaceutical products, such as erythropoietin, human growth hormone and interferons. Today, microbiology is a major participant in global industry, especially in the pharmaceutical, food and chemical industries. PMID:10631778

  18. Overlay improvement by ASML HOWA 5th alignment strategy

    Overlay control is more challenging when DRAM volume production continues to shrink its critical dimention (CD) to 70nm and beyond. Effected by process, the overlay behavior at wafer edge is quite different from wafer center. The big contribution to worse overlay at wafer edge which causes yield loss is misalignment. The analysis in wafer edge suggests that high order uncorrectable overlay residuals are often observed by certain process impact. Therefore, the basic linear model used for alignment correction is not sufficient and it is necessary to introduce an advanced alignment correction model for wafer edge overlay improvement. In this study, we demonstrated the achievement of moderating the poor overlay at wafer edge area by using a high order wafer alignment strategy. The mechanism is to use non-linear correction methods of high order models ( up to 5th order), with support by the function High Order Wafer Alignment (known as HOWA) in scanner. Instead of linear model for the 6 overlay parameters which come from average result, HOWA alignment strategy can do high order fitting through the wafer to get more accurate overlay parameters which represent the local wafer grid distortion better. As a result, the overlay improvement for wafer edge is achieved. Since alignment is a wafer dependent correction, with HOWA the wafer to wafer overlay variation can be improved dynamically as well. In addition, the effects of different mark quantity and sampling distribution from HOWA are also introduced in this paper. The results of this study indicate that HOWA can reduce uncorrectable overlay residual by 30~40% and improve wafer-to-wafer overlay variation significantly. We conclude that HOWA is a noteworthy strategy for overlay improvement. Moreover, optimized alignment mark numbers and distribution layout are also key factors to make HOWA successful.

    2013-02-01

    Full Text Available The game of cricket and the use of technology in the sport have grown rapidly over the past decade. However, technology-based systems introduced to adjudicate decisions such as run outs, stumpings, boundary infringements and close catches are still prone to human error, and thus their acceptance has not been fully embraced by cricketing administrators. In particular, technology is not employed for bat-pad decisions. Although the snickometer may assist in adjudicating such decisions it depends heavily on human interpretation. The aim of this study is to investigate the use of Wavelets in developing an edgedetection adjudication system for the game of cricket. Artificial Intelligence (AI tools, namely Neural Networks, will be employed to automate this edge detection process. Live audio samples of ball-on-bat and ball-on-pad events from a cricket match will be recorded. DSP analysis, feature extraction and neural network classification will then be employed on these samples. Results will show the ability of the neural network to differentiate between these key events. This is crucial to developing a fully automated edge detection system.

    2012-10-15

    The purpose of the present study was to compare the intra- and interobserver reliability of two different measurement methods for volar angulation of the 5th metacarpal (MC) in an attempt to establish a new standard measurement method to reduce interobserver discrepancies for therapeutic decisions. Twenty patients with subcapital fractures of the 5th MC were radiologically investigated. Imaging consisted of a radiographs in antero-posterior and precise lateral view in addition to a CT scan of the 5th MC. Measurement of volar angulation was accomplished using the conventional and the shaft articular surface (SAS) method. The measurements of five investigators were exported to a spreadsheet for statistical analysis to evaluate the intra-and interobserver reliability. The conventional technique showed large differences among the investigators and poor interobserver reliability (W = 0.328 and 0.307) both at injury (p = 0.001) and at follow-up (p = 0.189). The intraobserver concordance of all investigators showed better results with the SAS than with the conventional technique. With the SAS technique, no statistically significant difference among the investigators could be detected at either the time of injury (p = 0.418) or at follow-up (p = 0.526) with excellent interobserver reliability (W = 0.051 and W = 0.041). Evaluation of volar angulation at follow-up using CT scans did not show any statistically significant difference between the techniques with better correlation among the observers with the SAS technique (p = 0.838). The interobserver correlation of volar angulation with lateral radiographs using the conventional technique was insufficient. Therefore, we recommend the use of the novel SAS technique as standardized measurement method which showed higher accuracy and interobserver reliability in order to facilitate the choice of adequate treatment option.

    2012-09-01

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

    Surveillance testing for reactor vessel materials is performed in order to evaluate the irradiation embrittlement due to neutrons during operation and set the condition of safe operation of nuclear reactor. The 5th surveillance testing was performed primarily by Korea Atomic Energy Research Institute and Westinhouse corporation partially involved in testing and calculation data evaluation in order to obtain reliable test result. Fast neutron fluences for capsule V, T, S, R and P were 5.087E+18, 1.115E+19, 1.228E+19, 2.988E+19, and 3.938E+19n/cm2, respectively. The bias factor, the ratio of calculation/measurement, was 0.940 for the 1st through 5th testing and the calculational uncertainty, 7% satisfied the requirement of USNRC Reg.Guide DG-1053, 20%. The best estimated neutron fluence for reactor vessel inside surface was 1.9846E+19n/cm{sup 2} based on the end of 17th fuel cycle and it was predicted that the fluences of vessel inside surface at 24, 32, 40 and 48EFPY would reach 3.0593E+19, 4.0695E+19, 5.0797E+19 and 6.0900E+19n/cm{sup 2} based on the current calculation. PTS analysis for Kori unit 1 showed that 27.93EFPY was the threshold value for 300 deg F requirement. 71 refs., 33 figs., 52 tabs. (Author)

    The development of the first vaccines for use in animals, by Louis Pasteur at the end of the 19th Century, was an initial step in applying biotechnology to animal health. However, it is only much more recently that decisive progress has been made in finding applications for biotechnology, in both detecting and preventing infectious and parasitic diseases. This progress has shown the way to developing a range of procedures, the application of which will benefit the health of domestic and wild animals, enhance the well-being of companion animals, develop the performance of sporting animals and improve the productivity of farm animals, while also serving to protect human health. Such progress results from the increasingly rapid application of knowledge gained in the material and life sciences, all of which contribute to the multidisciplinary nature of biotechnology. Similarly, reagents and diagnostic techniques have been made more specific, sensitive, reproducible, rapid and robust by updating them through recent discoveries in immunology, biochemistry and molecular biology (monoclonal antibodies, nucleic probes, deoxyribonucleic acid amplification and many more). The development of new vaccines which combine efficacy, duration of protection, innocuity, stability, multivalence and ease of use (subunit vaccines, recombinant vaccines, synthetic vaccines and anti-idiotype vaccines) has resulted from recent progress in immunology, immunochemistry, molecular biology and biochemistry. Finally, the availability of new anti-infective, anti-parasitic agents and immunomodulatory therapeutic agents (capable of stimulating the specific and non-specific defence mechanisms of the body) demonstrates that biotechnology is continuing to find new applications in the field of animal health. New diagnostic techniques, vaccines and therapeutic substances are the most immediate applications of knowledge which may, in the future, extend to the development of transgenic animals of revised

    One change to the posttraumatic stress disorder (PTSD) nomenclature highlighted in the Diagnostic and Statistical Manual, 5th Edition (DSM-5; American Psychiatric Association, 2013) is the conceptualization of PTSD as a diagnostic category with four distinct symptom clusters. This article presents exploratory factor analysis to test the structural validity of the DSM-5 conceptualization of PTSD via an online survey that included the PTSD Checklist-5. The study utilized a sample of 113 college students from a large Midwestern university and 177 Amazon Mechanical Turk users. Participants were primarily female, Caucasian, single, and heterosexual with an average age of 32 years. Approximately 30% to 35% of participants met diagnostic criteria for PTSD based on two different scoring criteria. Results of the exploratory factor analysis revealed five distinct symptom clusters. The implications for the classification of PTSD are discussed.

    Surveillance testing for reactor vessel materials is performed in order to evaluate the irradiation embrittlement due to neutrons during operation and set the condition of safe operation of nuclear reactor. The 5th surveillance testing was performed completely by Korea Atomic Energy Research Institute at Taejeon after the capsule was transported from Kori site including its removal from reactor. Fast neutron fluences for capsules were calculated and various testing including mechanical and chemistry analysis were performed in order to evaluate the integrity of Kori unit 2 reactor vessel during the operation until life time. The evaluation results are as follows; Fast neutron fluences for capsules V, R, P, T and N are 2.837E+18, 1.105E+19, 2.110E+19, 3.705E+19 and 4.831E+19n/cm{sup 2}, respectively. The bias factor, the ratio of measurement/calculation, was 0.918 for the 1st through 5th testing and the calculational uncertainty, 11.6% satisfied the requirement of USNRC Reg.Guide DG-1053, 20%. The best estimated neutron fluence for reactor vessel inside surface was 1.898E+19n/cm{sup 2} based on the end of 15th fuel cycle and it was predicted that the fluences of vessel inside surface at 32, 40, 48 and 56EFPY would reach 4.203E+19, 5.232E+19, 6.262E+19 and 7.291E+19n/cm{sup 2} based on the current calculation. The result through this analysis for Kori unit 2 showed that there would be no problem for the pressurized thermal shock(PTS) during the operation until design life. 49 refs., 35 figs., 48 tabs.

    NASA is working with its international partners to develop space vehicles and facilities that will give researchers the opportunity to conduct scientific investigations in space. As part of this activity, NASA's Biotechnology Cell Science Program (BCSP) at the Johnson Space Center (JSC) is developing a world-class biotechnology laboratory facility for the International Space Station (ISS). This report describes the BCSP, including the role of the BTS. We identify the purpose and objectives of the BTS and a detailed description of BTS facility design and operational concept, BTS facility and experiment-specific hardware, and scientific investigations conducted in the facility. We identify the objectives, methods, and results of risk mitigation investigations of the effects of microgravity and cosmic radiation on the BTS data acquisition and control system. These results may apply to many other space experiments that use commercial, terrestrial-based data acquisition technology. Another focal point is a description of the end-to-end process of integrating and operating biotechnology experiments on a variety of space vehicles. The identification of lessons learned that can be applied to future biotechnology experiments is an overall theme of the report. We include a brief summary of the science results, but this is not the focus of the report. The report provides some discussion on the successful 130-day tissue engineering experiment performed in BTS on Mir and describes a seminal gene array investigation that identified a set of unique genes that are activated in space.

    This article focuses on analytical strategies integrating atomic spectroscopy in biotechnology. The rationale behind developing such methods is inherently linked to unique features of the key technique in elemental analysis, which is inductively coupled plasma mass spectrometry: (1) the high sensitivity and selectivity of state of the art instrumentation, (2) the possibility of accurate absolute quantification even in complex matrices, (3) the capability of combining elemental detectors with chromatographic separation methods and the versatility of the latter approach, (4) the complementarity of inorganic and organic mass spectrometry, (5) the multi-element capability and finally (6) the capability of isotopic analysis. The article highlights the most recent bio-analytical developments exploiting these methodological advantages and shows the potential in biotechnological applications.

    2002-06-01

    Recent advances in agricultural biotechnology have highlighted the need for experimental evidence and sound scientific judgment to assess the benefits and risks to society. Nutrition scientists and other animal biologists need a balanced understanding of the issues to participate in this assessment. To date most modifications to crop plants have benefited producers. Crops have been engineered to decrease pesticide and herbicide usage, protect against stressors, enhance yields and extend shelf life. Beyond the environmental benefits of decreased pesticide and herbicide application, consumers stand to benefit by development of food crops with increased nutritional value, medicinal properties, enhanced taste and esthetic appeal. There remains concern that these benefits come with a cost to the environment or increased risk to the consumer. Most U.S. consumers are not aware of the extent that genetically modified foods have entered the marketplace. Consumer awareness of biotechnology seems to have increased over the last decade, yet most consumers remain confused over the science. Concern over the impact on the safety of the food supply remains low in the United States, but is substantially elevated in Europe. Before a genetically engineered crop is introduced into commerce it must pass regulatory scrutiny by as many as four different federal regulatory bodies to ensure a safe food supply and minimize the risk to the environment. Key areas for more research are evaluation of the nutritional benefits of new crops, further investigation of the environmental impact, and development of better techniques to identify and track genetically engineered products.

    A new scientific and engineering discipline, Construction Biotechnology, is developing exponentially during the last decade. The major directions of this discipline are selection of microorganisms and development of the microbially-mediated construction processes and biotechnologies for the production of construction biomaterials. The products of construction biotechnologies are low cost, sustainable, and environmentally friendly microbial biocements and biogrouts for the construction ground improvement. The microbial polysaccharides are used as admixtures for cement. Microbially produced biodegradable bioplastics can be used for the temporarily constructions. The bioagents that are used in construction biotechnologies are either pure or enrichment cultures of microorganisms or activated indigenous microorganisms of soil. The applications of microorganisms in the construction processes are bioaggregation, biocementation, bioclogging, and biodesaturation of soil. The biotechnologically produced construction materials and the microbially-mediated construction technologies have a lot of advantages in comparison with the conventional construction materials and processes. Proper practical implementations of construction biotechnologies could give significant economic and environmental benefits. PMID:26070432

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

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

    Full Text Available Research studies in the area of biotechnologies in fruit growing started at the Agricultural Institute Osijek in 2006 with the establishment of the first experimental in vitro laboratory for micropropagation. The laboratory started an active research related to the Project "Biotechnological methods in fruit tree identification, selection and propagation" Project is part of program "Preservation and revitalization of grape and fruit autochthonous cultivars". The goal of this research is to determine genetic differences between autochthonous and introduced cultivars of cherry as well as cultivars and types of sour cherry, to find and optimize a method for fast recovery of clonal material. A great number of cherry cultivars and types within the population of cv. Oblacinska sour cherry exists in Croatia. A survey with the purpose of selecting autochthonous cultivars for further selection has been done in previous research. Differences have been found in a number of important agronomic traits within the populations of cv. Oblačinska sour cherry. Autochthonous cherry cultivars are suspected to be synonyms of known old cultivars which were introduced randomly and have been naturalized under a local name. Identification and description of cultivars and types of fruits is based on special visible properties which were measurable or notable. In this approach difficulties arise from the effect of non-genetic factors on expression of certain traits. Genetic-physiological problem of S allele autoincompatibility exists within cherry cultivars. Therefore it is necessary to put different cultivars in the plantation to pollinate each other. Apart form the fast and certain sort identification independent of environmental factors, biotechnological methods based on PCR enable faster virus detection compared with classical serologic methods and indexing and cover a wider range of plant pathogens including those undetectable by other methods.

Exciting new and ongoing discoveries show significant regulation of gene expression occurs after transcription. These post-transcriptional control events in plants range from subtle regulation of transcribed genes and phosphorylation, to the processes of gene regulation through small RNAs. This meeting will focus on the regulatory role of RNA, from transcription, through translation and finally degradation. The cross-disciplinary design of this meeting is necessary to encourage interactions between researchers that have a common interest in post-transcriptional gene expression in plants. By bringing together a diverse group of plant molecular biologist and biochemists at all careers stages from across the world, this meeting will bring about more rapid progress in understanding how plant genomes work and how genes are finely regulated by post-transcriptional processes to ultimately regulate cells.

    International Nuclear Information System (INIS)

    This fifth annual progress report details government progress in 2007 in tackling fuel poverty and movement towards targets. The United Kingdom were the first country in the world to recognise the issue of fuel poverty and to put in place measures to tackle the issue, including spending 20 billion pounds sterling on benefits and programmes since the year 2000. The report covers progress to date, schemes and initiatives to tackle fuel poverty, the energy market and looks ahead to the future. Progress and development of the schemes across the devolved nations are also considered. This report is the first to publish the Government's proposals for the Carbon Emissions Reduction Target (CERT) priority group, which were laid before Parliament on 5th December 2007. This report is the first to present the fuel poverty figures for 2005, and shows the effects of rising energy prices. The Government continues to take action to ensure that the energy market is working properly, and to encourage reform in the EU on energy market liberalisation - this should reduce pressure on prices.

    Cobal, M

    The 5th ATLAS physics workshop took place between the 6th and the 11th of June in Rome (after Trest '95, Grenoble '98, Lund '01, and Athens '03). This event turned out to be a great occasion to review the status of the physics and detector performance studies, under the beautiful sun of Rome. It is quite difficult to summarize the 100 talks (for a total of about 35 hours of presentations and discussions): I will just try to give here the general flavour of the workshop structure and conclusions. Four groups represented the Combined Detector Performances: Flavour tagging, E/gamma, Muon Combined and Jet/missing-transverse-energy/Tau. The main focus has been on the results of trigger studies: one introductory and one final talk provided the frame for more detailed presentations embedded in the relevant sessions. Progress was shown also from the Combined Testbeam analyses, where the data from the full ATLAS slice, collected in 2004, are being validated on real data reconstruction algorithms. During the physics ...

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

    Glass, D. S.

    2009-12-01

    I implemented the new NSF-funded SPRINTT (Student Polar Research with IPY National (and International) Teacher Training) curriculum with a 5th grade science class. SPRINTT, developed at U.S. Satellite Laboratory, Inc., is a 5-8 week science program teaching 5th through 10th graders to investigate climate change using polar data. The program includes perspectives of both Western scientists and the indigenous Northern population. The course contains three phases: Phase 1 includes content, data interpretation, and hands-on experiments to study Frozen Water, Frozen Land, and Food; Phase 2 (optional) includes further content on specific polar topics; and Phase 3 is a scaffolded research investigation. Before the course, teachers were trained via live webinars. This curriculum capitalizes on children’s innate fascination with our planet’s final frontier and combines it with the politically and scientifically relevant topic of climate change. In 2009, I used SPRINTT with 23 heterogeneous fifth grade students at National Presbyterian School in Washington DC for an environmental science unit. Overall, it was a success. The students met most of the learning objectives and showed enthusiasm for the material. I share my experiences to help other educators and curriculum developers. The Phase 1 course includes earth science (glaciers, sea ice, weather and climate, greenhouse gases, seasons, and human impacts on environments), life science (needs of living things, food and energy transfer, adaptations, and ecosystems and biomes) and physical science (phases of matter). Tailoring the program, I focused on Phase 1, the most accessible material and content, while deemphasizing the more cumbersome Phase 3 online research project. Pre-assessments documented the students’ misconceptions and informed instruction. The investigations were appropriately educational and interesting. For example, students enjoyed looking at environmental factors and their impact on the people in the

    Background Irregular burials (IB—burials showing features that contrast with the majority of others in their geographic and chronological context) have been the focus of archaeological study because of their relative rarity and enigmatic appearance. Interpretations of IB often refer to supposed fear of the dead or to social processes taking place in time-specific contexts. However, a comprehensive and quantitative analysis of IB for various geographical contexts is still lacking, a fact that hampers any discussion of these burials on a larger scale. Methods Here, we collected a bibliographic dataset of 375 IB from both Britain and Continental Europe, altogether spanning a time period from the 1st to the 5th century AD. Each burial has been coded according to ten dichotomous variables, further analyzed by means of chi-squared tests on absolute frequencies, non-metric multidimensional scaling, and cluster analysis. Results Even acknowledging the limits of this study, and in particular the bias represented by the available literature, our results point to interesting patterns. Geographically, IB show a contrast between Britain and Continental Europe, possibly related to historical processes specific to these regions. Different types of IB (especially prone depositions and depositions with the cephalic extremity displaced) present a series of characteristics and associations between features that permit a more detailed conceptualization of these occurrences from a socio-cultural perspective that aids to elucidate their funerary meaning. Conclusions and Significance Altogether, the present work stresses the variability of IB, and the need to contextualize them in a proper archaeological and historical context. It contributes to the discussion of IB by providing a specific geographic and chronological frame of reference that supports a series of hypotheses about the cultural processes possibly underlying their occurrence.

    Several three-dimensional (3D) finite element (FE) models of the human body have been developed to elucidate injury mechanisms due to automotive crashes. However, these models are mainly focused on 50(th) percentile male. As a first step towards a better understanding of injury biomechanics in the small female, a 3D FE model of a 5(th) percentile female human chest (FEM-5F) has been developed and validated against experimental data obtained from two sets of frontal impact, one set of lateral impact, two sets of oblique impact and a series of ballistic impacts. Two previous FE models, a small female Total HUman Model for Safety (THUMS-AF05) occupant version 1.0Beta (Kimpara et al. 2002) and the Wayne State University Human Thoracic Model (WSUHTM, Wang 1995 and Shah et al. 2001) were integrated and modified for this model development. The model incorporated not only geometrical gender differences, such as location of the internal organs and structure of the bony skeleton, but also the biomechanical differences of the ribs due to gender. It includes a detailed description of the sternum, ribs, costal cartilage, thoracic spine, skin, superficial muscles, intercostal muscles, heart, lung, diaphragm, major blood vessels and simplified abdominal internal organs and has been validated against a series of six cadaveric experiments on the small female reported by Nahum et al. (1970), Kroell et al. (1974), Viano (1989), Talantikite et al. (1998) and Wilhelm (2003). Results predicted by the model were well-matched to these experimental data for a range of impact speeds and impactor masses. More research is needed in order to increase the accuracy of predicting rib fractures so that the mechanisms responsible for small female injury can be more clearly defined. PMID:17096277

    Modern powerful techniques in plant biotechnology have been developed in lilies (Lilium spp., Liliaceae) to propagate, improve and make new phenotypes. Reliable in vitro culture methods are available to multiply lilies rapidly and shorten breeding programs. Lilium is also an ideal model plant to study in vitro pollination and embryo rescue methods. Although lilies are recalcitrant to genetic manipulation, superior genotypes are developed with improved flower colour and form, disease resistance and year round forcing ability. Different DNA molecular markers have been developed for rapid indirect selection, genetic diversity evaluation, mutation detection and construction of Lilium linkage map. Some disease resistance-QTLs are already mapped on the Lilium linkage map. This review presents latest information on in vitro propagation, genetic engineering and molecular advances made in lily.

    2015-11-01

    This volume of Journal of Physics: Conference Series is dedicated to the scientific research presented during the 5th International Workshop on New Computational Methods for Inverse Problems, NCMIP 2015 (http://complement.farman.ens-cachan.fr/NCMIP_2015.html). This workshop took place at Ecole Normale Supérieure de Cachan, on May 29, 2015. The prior editions of NCMIP also took place in Cachan, France, firstly within the scope of ValueTools Conference, in May 2011, and secondly at the initiative of Institut Farman, in May 2012, May 2013 and May 2014. The New Computational Methods for Inverse Problems (NCMIP) workshop focused on recent advances in the resolution of inverse problems. Indeed, inverse problems appear in numerous scientific areas such as geophysics, biological and medical imaging, material and structure characterization, electrical, mechanical and civil engineering, and finances. The resolution of inverse problems consists of estimating the parameters of the observed system or structure from data collected by an instrumental sensing or imaging device. Its success firstly requires the collection of relevant observation data. It also requires accurate models describing the physical interactions between the instrumental device and the observed system, as well as the intrinsic properties of the solution itself. Finally, it requires the design of robust, accurate and efficient inversion algorithms. Advanced sensor arrays and imaging devices provide high rate and high volume data; in this context, the efficient resolution of the inverse problem requires the joint development of new models and inversion methods, taking computational and implementation aspects into account. During this one-day workshop, researchers had the opportunity to bring to light and share new techniques and results in the field of inverse problems. The topics of the workshop were: algorithms and computational aspects of inversion, Bayesian estimation, Kernel methods, learning methods

    2010-12-01

    At the "5th International Meeting on Inflammatory Bowel Diseases selected topics of inflammatory bowel disease (IBD), including the environment, genetics, the gut flora, the cell response and immunomodulation were discussed in order to better understand specific clinical and therapeutic aspects. The incidence of IBD continues to rise, both in low and in high-incidence areas. It is believed that factors associated with 'Westernization' may be conditioning the expression of these disorders. The increased incidence of IBD among migrants from low-incidence to high-incidence areas within the same generation suggests a strong environmental influence. The development of genome-wide association scanning (GWAS) technologies has lead to the discovery of more than 100 IBD loci. Some, as the Th 17 pathway genes, are shared between Crohn's disease (CD) and ulcerative colitis (UC), while other are IBD subtype-specific (autophagy genes, epithelial barrier genes). Disease-specific therapies targeting these pathways should be developed. Epigenetic regulation of the inflammatory response also appears to play an important role in the pathogenesis of IBD. The importance of gut flora in intestinal homeostasis and inflammation was reinforced, the concepts of eubiosis and dysbiosis were introduced, and some strategies for reverting dysbiosis to a homeostatic state of eubiosis were proposed. The current status of studies on the human gut microbiota metagenome, metaprotome, and metabolome was also presented. The cell response in inflammation, including endoplasmic reticulum (ER) stress responses, autophagy and inflammasome-dependent events were related to IBD pathogenesis. It was suggested that inflammation-associated ER stress responses may be a common trait in the pathogenesis of various chronic immune and metabolic diseases. How innate and adaptive immunity signaling events can perpetuate chronic inflammation was discussed extensively. Signal transduction pathways provide intracellular

    Full Text Available Access to the right to the highest attainable level of health is a constitutional right that obliges governments and other players to take step to increase all individuals’ chances of obtaining good health. At the least, health and education are two crucial requirements for this as well. Iran's vision 2025 is going to lead the country to a developed state with the highest rank of economic, scientific and technological status in the region. Enjoying health, welfare, food security, social security, equal opportunities, etc, are also considered as part of characteristics of Iranian society in 2025. Although health system of Iran has many achievements in providing health services specially for the poor following the Islamic Revolution of 1979, but the evidences gathered to develop the 5th 5-years economical, social and cultural plan (5th5YDP:2011-2015, listed a variety of main challenges in stewardship, financing, resources generation and service provision functions of the existing health system. Thus, to overcome the main challenges, about 11% of general policies of 5th5YDP are directly address health related issues with emphasizing on healthy human and comprehensive health approach with considering: Integration of policy making, planning, evaluation, supervision and public financing; Developing both quantity and quality of health insurance system and reducing out-of-pocket expenditures for health services to 30% by the end of the 5th plan. The strategies of 5th5YDP adopted by the parliament as an Act will change the health system fundamentally through tuning the main drivers; so, its implementation needs brave leaders, capable managers, motivated technical staff and social mobilization.

    Venture capital has guaranteed the successful launch of biotechnology in the US since 1977. Established companies are then licensed to produce and distribute the latest inventions. By contrast in Japan established industrial companies are the leaders in biotechnology research, development and commercialization, building on existing technology and past experience and retraining staff. In the US electronics industry the acute shortage of electronic engineers combined with the high cost of capital and instability within venture capital companies to restrict the high level of innovation required looks likely to happen again in biotechnology.

    Full Text Available The wave of biotechnology promises has struck not only the developed countries but the developing countries as well. The scientific community in Indonesia is aware of the opportunities and is eager to take an active part in this particular endeavour. Meanwhile resources are required to welcoming the biotech­nology era. The need of trained manpower, appropriate infrastructure and equipment, operational and maintenance costs requires serious consideration if a unit or a laboratory is expected to be functional in biotechnology. There is a good opportunity of applying biotechnology in the field of agriculture and industry considering the availability of biological resources in Indonesia. This paper outlines what have been done so far, the difficulties encountered and the efforts made to strengthening biotechnology research in Indonesia.

    2016-03-01

    Riboflavin (vitamin B2) production has shifted from chemical synthesis to exclusive biotechnological synthesis in less than 15 years. The underlying extraordinary achievement in metabolic engineering and bioprocess engineering is reviewed in this article with regard to the two most important industrial producers Bacillus subtilis and Ashbya gossypii. The respective biosynthetic routes and modifications are discussed, and also the regulation of riboflavin synthesis. As the terminal biosynthesis of riboflavin starts from the two precursors, ribulose 5-phosphate and guanosine triphosphate (GTP), both strains have been optimized for an improved flux through the pentose phosphate pathway as well as the purine biosynthetic pathway. Specific targets for improvement of A. gossypii were the increase of the glycine pool and the increase of carbon flow through the glyoxylic shunt. In B. subtilis, research interest, amongst others, has focused on gluconeogenesis and overexpression of the rib operon. In addition, insight into large-scale production of vitamin B2 is given, as well as future prospects and possible developments. PMID:26758294

  8. New Directions in Biotechnology

    The macromolecule crystallization program within NASA is undergoing considerable pressure, particularly budgetary pressure. While it has shown some successes, they have not lived up to the expectations of others, and technological advances may rapidly overtake the natural advantages offered by crystallization in microgravity. Concomitant with the microgravity effort has been a research program to study the macromolecule crystallization process. It was believed that a better understanding of the process would lead to growth of improved crystals for X-ray diffraction studies. The results of the various research efforts have been impressive in improving our understanding of macromolecule crystallization, but have not led to any improved structures. Macromolecule crystallization for structure determination is "one of", the job being unique for every protein and finished once a structure is obtained. However, the knowledge gained is not lost, but instead lays the foundation for developments in new areas of biotechnology and nanotechnology. In this it is highly analogous to studies into small molecule crystallization, the results of which have led to our present day microelectronics-based society. We are conducting preliminary experiments into areas such as designed macromolecule crystals, macromolecule-inorganic hybrid structures, and macromolecule-based nanotechnology. In addition, our protein crystallization studies are now being directed more towards industrial and new approaches to membrane protein crystallization.

    Tan, Tony Xing

    2016-10-01

    Existing theories (e.g., acculturative stress theory) cannot adequately explain why mental disorders in immigrants are less prevalent than in non-immigrants. In this paper, the culture-gene co-evolutionary theory of mental disorders was utilized to generate a novel hypothesis that connection to heritage culture reduces the risk for mental disorders in immigrant children. Four groups of children aged 2-17 years were identified from the 2007 United States National Survey of Children's Health: 1.5th generation immigrant children (n = 1378), 2nd generation immigrant children (n = 4194), foreign adoptees (n = 270), and non-immigrant children (n = 54,877). The 1.5th generation immigrant children's connection to their heritage culture is stronger than or similar to the 2nd generation immigrants, while the foreign adoptees have little connection to their birth culture. Controlling for age, sex, family type and SES, the odds for having ADD/ADHD, Conduct Disorder, Anxiety Disorder, and Depression diagnosis were the lowest for the 1.5th generation immigrant children, followed by the 2nd generation immigrant children and the foreign adoptees. The foreign adoptees and non-adopted children were similar in the odds of having these disorders. Connection to heritage culture might be the underlying mechanism that explained recent immigrants' lower rates of mental disorders. PMID:26972324

    This special issue of Journal of Physics A: Mathematical and Theoretical appears on the occasion of the 5th International Symposium on Quantum Theory and Symmetries (QTS5), held in Valladolid, Spain, from 22-28 July 2007. This is the fith in a series of conferences previously held in Goslar (Germany) 1999, QTS1; Cracow (Poland) 2001, QTS2; Cincinnati (USA) 2003, QTS3; and Varna (Bulgaria) 2005, QTS4. The QTS5 symposium gathered 181 participants from 39 countries working in different fields of theoretical physics. The spirit of the QTS conference series is to join researchers in a wide variety of topics in theoretical physics, as a way of making accessible recent results and the new lines of different fields. This is based on the feeling that it is good for a physicist to have a general overview as well as expertise in his/her own field. There are many other conferences devoted to specific topics, which are of interest to gain deeper insight in many technical aspects and that are quite suitable for discussions due to their small size. However, we believe that general conferences like this are interesting and worth keeping. We like the talks, in both plenary and parallel sessions, which are devoted to specific topics, to be prepared so as to be accessible to any researcher in any branch of theoretical physics. We think that this objective is compatible with rigour and high standards. As is well known, similar methods and techniques can be useful for many problems in different fields. We hope that this has been appreciated during the sessions of the QTS5 conference. The QTS5 conference offered the following list of topics: 1. Symmetries in string theory, quantum gravity and related topics 2. Symmetries in quantum field theories, conformal and related field theories, lattice and noncommutative theories, gauge theories 3.Quantum computing, information and control 4. Foundations of quantum theory 5. Quantum optics, coherent states, Wigner functions 6. Dynamical and

  15. Yeast Genetics and Biotechnological Applications

    Science.gov (United States)

    Mishra, Saroj; Baranwal, Richa

    Yeast can be recognized as one of the very important groups of microorganisms on account of its extensive use in the fermentation industry and as a basic eukaryotic model cellular system. The yeast Saccharomyces cerevisiae has been extensively used to elucidate the genetics and regulation of several key functions in the cell such as cell mating, electron transport chain, protein trafficking, cell cycle events and others. Even before the genome sequence of the yeast was out, the structural organization and function of several of its genes was known. With the availability of the origin of replication from the 2 μm plasmid and the development of transformation system, it became the host of choice for expression of a number of important proteins. A large number of episomal and integrative shuttle vectors are available for expression of mammalian proteins. The latest developments in genomics and micro-array technology have allowed investigations of individual gene function by site-specific deletion method. The application of metabolic profiling has also assisted in understanding the cellular network operating in this yeast. This chapter is aimed at reviewing the use of this system as an experimental tool for conducting classical genetics. Various vector systems available, foreign genes expressed and the limitations as a host will be discussed. Finally, the use of various yeast enzymes in biotechnology sector will be reviewed.

  17. Cosmetics - chemical technology or biotechnology?

    Science.gov (United States)

    Allen, G

    1984-04-01

    Synopsis Over the past 25 years the cosmetic industry has become increasingly technological. The origins of many of these advances were based upon chemical technology usually related to colloid science, although more recent developments have had clear biological improvements. A number of recent innovations are examined to consider how far developments in the future will stem from biotechnology rather than chemical technology. The working of surface active materials (e.g. CTAB) is discussed as an example of cosmetic effects being generated purely from chemical technology. The role of fluoride toothpaste in decreasing the incidence of dental caries is discussed as an effect based essentially on chemical technology in an area where future alternatives might come from biotechnology. Skin research is highlighted as the area where new understanding, e.g. of the role of epidermal growth factor (EGF), fibronectin and laminin, could lead to a whole new biotechnological approach to the appraisal of skin. As we venture into innovations based on biotechnology we may be introducing new dimensions in product safety which will need an even closer relationship with the medical fraternity. Consequently the introduction of products based on biotechnology may not be as rapid as is sometimes suggested.

  18. The role of biotechnology in combating climate change: A question of politics

    DEFF Research Database (Denmark)

    Aerni, Philipp; Gagalac, Florabelle; Scholderer, Joachim

    2016-01-01

    Biotechnology is a platform technology that may significantly contribute to climate change mitigation and adaptation. Yet, biotechnology is hardly ever referred to as “clean technology”. This paper investigates why biotechnology tends to be ignored in this context. A global stakeholder survey on...... biotechnology and climate change was conducted with 55 representatives of 44 institutions. The results of a perception pattern analysis show that the majority of stakeholder representatives had a neutral or positive attitude towards the use of biotechnology and regarded its potential to address climate change...... problems as significant. The survey results further reveal a significant relationship between a representative’s institutional and disciplinary background and his or her attitude. The respective background appears to determine to a considerable extent whether biotechnology is framed as a risk or an...

    Full Text Available Biotechnology, in its present perspective, encompasses activities, such as recombination of genes; cloning, or making genetically identical copies of a living thing; and splicing of genes from DNA of one organism into the genome of unrelated species, to create new, self-reproducing forms of life. The vast potential of biotechnology is being increasingly realised, and efforts are in progress to harness it for improving quality and quantity of bio-weapons, The bio-weapons, as such, are highly attractive because of their non-detection by routine security systems, ease of access, low production cost and easy transportation, A wide range of genetically manipulated organisms and their by-products are considered to have an added advantage, because these genetically manipulated biologics not only accentuate the existing properties of bio-weapons, but also could be made target-specific. Biotechnology, if used prudently, can play a significant role to counter such threats of biologics, viz., by producing (i bio-armoury comprising powerful antibiotics, antisera toxoids and vaccines to neutralise and eliminate a wide range of diseases, and (ii bio-sensors for rapid detection, identification and neutralisation of biological warfare agents. This article elucidates some facets of biological warfare, legal protective strategies emphasised through international consultation, cooperation and adherence to the Biological and Toxin Weapons Convention, and discusses how biotechnology could be effectively used to strengthen countries' defence and combat the threat of biological warfare.

    2000-03-01

    Since the 1995 International Workshop on Railway Noise in Voss, two major elements may be considered as influential to railway noise research:— there is a clear and strong demand, at the European level as well as nationally for reducing railway noise in terms of operational solutions, especially for freight traffic,— theoretical developments for modelling rolling noise (which is the major source of noise for conventional speed) reached a point where operational developments of low noise solutions could be successfully carried out with the Twins model.Accordingly, research focused on developing such low noise solutions for rolling noise, investigating subsidiary and still unanswered questions, and addressing outstanding problems related to aerodynamic noise. In parallel to these propagation and annoyance studies were the subject of continuing interests, either with practical results or detailed on-going studies. Finally, modelling interior noise either with modal approaches for lower frequencies, or with SEA for higher frequencies, have proved successful in the case of high speed. Emerging subjects involve a revival of groundborne vibration modelling, roughness generation studies and decision management systems to get the greatest benefit from various potential solutions.

    The 5th International Conference on Materials and Applications for Sensors and Transducers, Mykonos island, Greece, hosted about 110 oral and poster papers and more than 90 participants. IC-MAS, as an international annual conference which tries to meet the needs for various types of sensors, particularly those which may be manufactured by low cost methods (i.e. hybrid sensors, smart specialization devices, particular applications not necessarily requiring integrated micro-nano technologies), covering all types of materials and physical effects, appears to be a necessity. IC-MAST has been established as a high quality international conference by: I. Gathering together multinational researchers from all over the world, working in different materials for sensors and transducers and technical applications of sensors, but also in some cases in the management of the data coming from sensors and transducers. The careful selection of the conference place (like Aegean Sea, Budapest, Prague, Bilbao, Mykonos etc) allows for enjoying the local hospitality and sightseeing. II.

    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.

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

    International Nuclear Information System (INIS)

    In 1980 the site of a vanadium and uranium mill at Monticello, Utah, was accepted into the US Department of Energy's (DOE's) Surplus Facilities Management Program, with the objectives of restoring the government-owned mill site to safe levels of radioactivity, disposing of or containing the tailings in an environmentally safe manner, and performing remedial actions on off-site (vicinity) properties that had been contaminated by radioactive material resulting from mill operations. During 1984 UNC Geotech, the remedial action contractor designated by DOE, performed remedial action on the vicinity property at 16 East 5th South Street, Monticello, Utah. The Pollutant Assessments Group (PAG) of Oak Ridge National Laboratory was assigned the responsibility of verifying the data supporting the adequacy of remedial action and confirming the site's compliance with DOE guidelines. The PAG found that the site successfully meets the DOE remedial action objectives. Procedures used by PAG are described. 3 refs., 2 tabs

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

  7. Interface of nuclear and biotechnologies

    International Nuclear Information System (INIS)

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

    The continued development of new cell culture technology is essential for the future growth and application of insect cell and baculovirus biotechnology. The use of cell lines for academic research and for commercial applications is currently dominated by two cell lines; the Spodoptera frugiperda line, SF21 (and its clonal isolate, SF9), and the Trichoplusia ni line, BTI 5B1-4, commercially known as High Five cells. The long perceived prediction that the immense potential application of the baculovirus-insect cell system, as a tool in cell and molecular biology, agriculture, and animal health, has been achieved. The versatility and recent applications of this popular expression system has been demonstrated by both academia and industry and it is clear that this cell-based system has been widely accepted for biotechnological applications. Numerous small to midsize startup biotechnology companies in North America and the Europe are currently using the baculovirus-insect cell technology to produce custom recombinant proteins for research and commercial applications. The recent breakthroughs using the baculovirus-insect cell-based system for the development of several commercial products that will impact animal and human health will further enhance interest in this technology by pharma. Clearly, future progress in novel cell and engineering advances will lead to fundamental scientific discoveries and serve to enhance the utility and applications of this baculovirus-insect cell system.

    Despite rapid growth of the biotechnology industry worldwide, a number of public concerns about the application of biotechnology and its regulation remain. In response to these concerns, greater emphasis has been placed on promoting biotechnologists' public engagement. As tertiary science degree programmes form the foundation of the biotechnology sector by providing a pipeline of university graduates entering into the profession, it has been proposed that formal science communication training be introduced at this early stage of career development. The aim of the present study was to examine the views of biotechnology students towards science communication and science communication training. Using an Australian biotechnology degree programme as a case study, 69 undergraduates from all three years of the programme were administered a questionnaire that asked them to rank the importance of 12 components of a biotechnology curriculum, including two science communication items. The results were compared to the responses of 274 students enrolled in other science programmes. Additional questions were provided to the second year biotechnology undergraduates and semi-structured interviews were undertaken with 13 of these students to further examine their views of this area. The results of this study suggest that the biotechnology students surveyed do not value communication with non-scientists nor science communication training. The implications of these findings for the reform of undergraduate biotechnology courses yet to integrate science communication training into their science curriculum are discussed.

    Full Text Available Fast food consumption is a dietary factor associated with higher prevalence of childhood obesity in the United States. The association between food prices and consumption of fast food among 5th and 8th graders was examined using individual-level random effects models utilizing consumption data from the Early Childhood Longitudinal Study, Kindergarten Class of 1998-99 (ECLS-K, price data from American Chamber of Commerce Researchers Association (ACCRA, and contextual outlet density data from Dun and Bradstreet (D&B. The results found that contextual factors including the price of fast food, median household income, and fast food restaurant outlet densities were significantly associated with fast food consumption patterns among this age group. Overall, a 10% increase in the price of fast food was associated with 5.7% lower frequency of weekly fast food consumption. These results suggest that public health policy pricing instruments such as taxes may be effective in reducing consumption of energy-dense foods and possibly reducing the prevalence of overweight and obesity among US children and young adolescents.

    Rooted in science education and science communication studies, this study examines 4th and 5th grade students' perceptions of science information sources (SIS) and their use in communicating science to students. It combines situated learning theory with uses and gratifications theory in a qualitative phenomenological analysis. Data were gathered through classroom observations and interviews in four Turkish elementary schools. Focus group interviews with 47 students and individual interviews with 17 teachers and 10 parents were conducted. Participants identified a wide range of SIS, including TV, magazines, newspapers, internet, peers, teachers, families, science centers/museums, science exhibitions, textbooks, science books, and science camps. Students reported using various SIS in school-based and non-school contexts to satisfy their cognitive, affective, personal, and social integrative needs. SIS were used for science courses, homework/project assignments, examination/test preparations, and individual science-related research. Students assessed SIS in terms of the perceived accessibility of the sources, the quality of the content, and the content presentation. In particular, some sources such as teachers, families, TV, science magazines, textbooks, and science centers/museums ("directive sources") predictably led students to other sources such as teachers, families, internet, and science books ("directed sources"). A small number of sources crossed context boundaries, being useful in both school and out. Results shed light on the connection between science education and science communication in terms of promoting science learning.

    Full Text Available A 36-year-old female patient was admitted to our clinic with complaints of numbness in hands, double vision, and inability to close her left eye. Her physical examination revealed horizontal diplopia, underactivity of the left lateral rectus muscle, left peripheral facial paralysis, and trigeminal sensorial neuropathy. The magnetic resonance imaging revealed hyperintense lesions, which were compatible with multiple sclerosis (MS. Therefore, systemic steroid treatment (1000 mg/day intravenous methylprednisolone for 5 days, 1 mg/ kg/day oral prednisolone, reduced slowly was administered to the patient. Within five weeks, her symptoms were regressed, and no recurrence was observed during the follow-up period of 4 years. As this case proves, MS can present with cranial nerve palsies in addition to many other different neurological symptoms. Although 5th nerve palsy is the most common cranial nerve palsy detected in MS patients, 7th and 6th nerve involvement are rarely reported in the literature. MS should always be considered in the differential diagnosis of cranial nerve palsies especially in young patients. (Turk J Ophthalmol 2015; 45: 81-3

    This study compares the spatial characteristics of industrial R&D networks to those of public research R&D networks (i.e. universities and research organisations). The objective is to measure the impact of geographical separation effects on the constitution of cross-region R&D collaborations for both types of collaboration. We use data on joint research projects funded by the 5th European Framework Programme (FP) to proxy cross-region collaborative activities. The study area is composed of 255 NUTS-2 regions that cover the EU-25 member states (excluding Malta and Cyprus) as well as Norway and Switzerland. We adopt spatial interaction models to analyse how the variation of cross-region industry and public research networks is affected by geography. The results of the spatial analysis provide evidence that geographical factors significantly affect patterns of industrial R&D collaboration, while in the public research sector effects of geography are much smaller. However, the results show that te...

    2011-12-01

    Animation has great potential for improving the way people learn. A number of studies in different scientific disciplines have shown that instruction involving computer animations can facilitate the understanding of processes at the molecular level. However, using animation alone does not ensure learning. Students sometimes miss essential features when they watch only animations, mainly due to the cognitive load involved. Moreover, students seem to attribute a great deal of authority to the computer and may develop misconceptions by taking animations of abstract concepts too literally. In this study, we attempted to explore teachers' perceptions concerning the use of animations in the classroom while studying biotechnological methods, as well as the teachers' contribution to the enactment of animations in class. Thirty high-school biotechnology teachers participated in a professional development workshop, aimed at investigating how teachers plan for and support learning with animation while studying biotechnological methods in class. From that sample, two teachers agreed to participate in two case studies aimed at characterizing teachers' contribution to the enactment of animations in class while studying biotechnological methods. Our findings reveal marked teacher contribution in the following three aspects: establishing the "hands-on" point of view, helping students deal with the cognitive load that accompanies the use of animation, and implementing constructivist aspects of knowledge construction while studying using animations.

    With the advent of a new era of astrobiology missions in the exploration of the solar system and the search for evidence of life elsewhere, we present a new approach to this goal, the integration of biotechnology. We have reviewed the current list of biotechnology techniques, which are applicable to miniaturization, automatization and integration into a combined flight platform. Amongst the techniques reviewed are- The uses of antibodies- Fluorescent detection strategies- Protein and DNA chip technology- Surface plasmon resonance and its relation to other techniques- Micro electronic machining (MEMS where applicable to biologicalsystems)- nanotechnology (e.g. molecular motors)- Lab-on-a-chip technology (including PCR)- Mass spectrometry (i.e. MALDI-TOF)- Fluid handling and extraction technologies- Chemical Force Microscopy (CFM)- Raman Spectroscopy We have begun to integrate this knowledge into a single flight instrument approach for the sole purpose of combining several mutually confirming tests for life, organic and/or microbial contamination, as well as prebiotic and abiotic organic chemicals. We will present several innovative designs for new instrumentation including pro- engineering design drawings of a protein chip reader for space flight and fluid handling strategies. We will also review the use of suitable extraction methodologies for use on different solar system bodies.

    This paper focuses on application of the recent biotechnology and introduces its new trends. What has triggered the boom in the application is when the technology has been applied to medicines in the 1970's. Beginning with insulin and interferon, various fibrinolytic agents including tPA and monoclonals have been put on markets one after another in 1991. Progress in humangenomic analysis has led to implementation of gene therapies and diagnoses using genes on gene diseases. Sweeteners used in a large quantity in the foodstuff field are fructoses made by isomerizing glucose produced by using enzymatic bioreactors. Needless to say about production of amino acid, organic acids, saccharides, antibiotics, steroids, and nucleic acid-based compounds by using enzymatic bioreactors, chemicals including acrylic amide from acrylonitrile, enzyme detergents, and bio-herbicides are available commercially. Progress in the technology is seen in all of the fields, including electronics industry and environmental preservation. 6 refs., 4 figs.

    Straub, Jürg Oliver; Shearer, Russel; Studer, Martin

    2014-09-01

    The biotechnological production of pharmaceutical active substances needs ancillary substances. Surfactants are used at the end of the cell culture as a protection against potential viral or bacterial contamination and to lyse the producing cells for isolation and purification of the products. To find a replacement for a surfactant that had raised environmental concern, environmentally relevant data for potential alternatives were searched for in the literature. Significant data gaps were filled with additional tests: biodegradability, algal growth inhibition, acute daphnid immobilization and chronic daphnid reproduction toxicity, acute fish toxicity, and activated sludge respiration inhibition. The results were used to model removal in the wastewater treatment plants (WWTPs) serving 3 biotechnological production sites in the Roche Group. Predicted environmental concentrations (PECs) were calculated using realistic amounts of surfactants and site-specific wastewater fluxes, modeled removals for the WWTPs and dilution factors by the respective receiving waters. Predicted no-effect concentrations (PNECs) were derived for WWTPs and for both fresh and marine receiving waters as the treated wastewater of 1 production site is discharged into a coastal water. This resulted in a spreadsheet showing PECs, PNECs, and PEC ÷ PNEC risk characterization ratios for the WWTPs and receiving waters for all investigated surfactants and all 3 sites. This spreadsheet now serves as a selection support for the biotechnological developers. This risk-based prioritization of surfactants is a step toward green biotechnological production.

    Are science educators providing secondary school students with the background to understand the science behind recent controversies such as the recently introduced compulsory labelling of genetically modified foods? Research from the UK suggests that many secondary school students do not understand the processes or implications of modern biotechnology. The situation in Australia is unclear. In this study, 1116 15-year-old students from eleven Western Australian schools were surveyed to determine their understanding of, and attitude towards, recent advances in modern biotechnology. The results indicate that approximately one third of students have little or no understanding of biotechnology. Many students over-estimate the use of biotechnology in our society by confusing current uses with possible future applications. The results provide a rationale for the inclusion of biotechnology, a cutting edge science, in the school science curriculum

    Detection of orthostatic hypotension (OH) is very important in geriatric practice, since OH is associated with mortality, ischemic stroke, falls, cognitive failure and depression. It was aimed to determine the most appropriate time for measuring blood pressure in transition from supine to upright position in order to diagnose OH in elderly. Comprehensive geriatric assessment (CGA) including Head up Tilt Table (HUT) test was performed in 407 geriatric patients. Orthostatic changes were assessed separately for the 1st, 3rd and 5th minutes (HUT1, HUT3 and HUT5, respectively) taking the data in supine position as the basis. The mean age, recurrent falls, presence of dementia and Parkinson's disease, number of drugs, alpha-blocker and anti-dementia drug use, and fasting blood glucose levels were significantly higher in the patients with versus without OH; whereas, albumin and 25-hydroxy vitamin D levels were significantly lower (p<0.05). However, different from HUT3 and HUT5, Charlson Comorbidity Index and the prevalence of diabetes mellitus were higher, the use of antidiabetics, antipsychotics, benzodiazepine, opioid and levodopa were more common (p<0.05). Statistical significance of the number of drugs and fasting blood glucose level was prominent in HUT1 as compared to HUT3 (p<0.01, p<0.05). Comparison of the patients that had OH only in HUT1, HUT3or HUT5 revealed no difference in terms of CGA parameters. These results suggests that orthostatic blood pressure changes determined at the 1st minute might be more important for geriatric practice. Moreover, 1st minute measurement might be more convenient in the elderly as it requires shorter time in practice. PMID:27077324

    Full Text Available The term ‘value’ has been used in many different meanings until today in different areas and it has been the reason for confusion in values education. In this sense, Weber (1990 has stated that different approaches to the term ‘value’ have played a negative role for the production of values. Kohlberg (1981 has defined ‘value’ as giving moral decisions and acting accordingly while Hill (1991 interpreted values as the beliefs that people care and direct the life of individuals. On the other hand, Veugelers (2000 defined values as the beliefs that help individuals to decide what is good or evil. International organizations also saw the need to define values in accordance with their missions. In the Declaration of Human Rights by the United Nations, it is indicated that education should strengthen human rights and freedom while supporting tolerance among different religious groups, ethnicities and nations (Universal Declaration of Human Rights, 1948. UNESCO is another organization that defined the role of values in education. According to the report by UNESCO, education becomes valuable if one learns (a how to know (b how to do, (c how to live together and (d how to be. In this sense, UNESCO has also claimed that in order to develop intercultural and interfaith dialogue, common values accepted by everyone should be given in schools. It has been observed that critical thinking and problem solving skills were given in values education programs in western societies while those skills have started to be taught in Turkey recently. In this study, the main values education movements and the processes and principles of teaching values education in real life are analyzed. We looked at the place of values education in 4th and 5th grade Social Studies textbooks in Turkey. After analyzing the basic processes and principles of values education, we looked at the values to be given to the students in the textbooks. Values education approaches have

Significant advances have been made in red biotechnology using pharmaceutically and medically relevant applications, green biotechnology developing agricultural and environmental tools and white biotechnology serving industrial scale uses, frequently as process feedstocks. Red biotechnology has delivered dramatic improvements in controlling human disease, from antibiotics to overcome bacterial infections to anti-HIV/AIDS pharmaceuticals such as azidothymidine (AZT), anti-malarial compounds and novel vaccines saving millions of lives. Green biotechnology has dramatically increased food production through Agrobacterium and biolistic genetic modifications for the development of 'Golden Rice', pathogen resistant crops expressing crystal toxin genes, drought resistance and cold tolerance to extend growth range. The burgeoning area of white biotechnology has delivered bio-plastics, low temperature enzyme detergents and a host of feedstock materials for industrial processes such as modified starches, without which our everyday lives would be much more complex. Biotechnological applications can bridge these categories, by modifying energy crops properties, or analysing circulating nucleic acid elements, bringing benefits for all, through increased food production, supporting climate change adaptation and the low carbon economy, or novel diagnostics impacting on personalized medicine and genetic disease. Cross-cutting technologies such as PCR, novel sequencing tools, bioinformatics, transcriptomics and epigenetics are in the vanguard of biotechnological progress leading to an ever-increasing breadth of applications.

    Multiple-choice-questions are common in medical examinations, but guessing biases assessment results. Confidence-based-testing (CBT) integrates indicated confidence levels. It has been suggested that correctness of and confidence in an answer together indicate knowledge levels thus determining the quality of a resulting decision. We used a CBT approach to investigate whether decision quality improves during undergraduate medical education. 3rd- and 5th-year students attended formative multiple-choice exams on pharmacological issues. Students were asked to indicate their confidence in a given answer. Correctness of answers was scored binary (1-correct; 0-wrong) and confidence levels were transformed to an ordinal scale (guess: 0; rather unsure: 0.33; rather sure: 0.66; very sure: 1). 5th-year students gave more correct answers (73 ± 16 vs. 49 ± 13 %, p confident regarding the correctness of their answers (0.61 ± 0.18 vs. 0.46 ± 0.13, p students (r = 0.81 vs. r = 0.52), but agreement of confidence and correctness ('centration') was lower. By combining the Bland-and-Altman approach with categories of decision-quality we found that 5th-year students were more likely to be 'well-informed' (41 vs. 5 %), while more 3rd-students were 'uninformed' (24 vs. 76 %). Despite a good correlation of exam results and confidence in given answers increased knowledge might be accompanied by a more critical view at the own abilities. Combining the statistical Bland-and-Altman analysis with a theoretical approach to decision-quality, more advanced students are expected to apply correct beliefs, while their younger fellows are rather at risk to hesitate or to act amiss.

    Cleanup and treatment of hazardous wastes incur major operational costs for the U.S. Air Force. Bioremediation can provide a cost-effective alternative to traditional technologies for a wide range of natural organic compounds such as jet fuel. Bioventing and natural attenuation are emerging as treatments of choice in many instances. Synthetic organic chemicals are much more resistant to biodegradation. However, recent advances in biotechnology allow the development of strains able to use nitro- and chloro-substituted organic compounds as their sole source of carbon and energy. Current basic research is focused on expanding the range of synthetic chemicals amenable to biodegradation. At the same time, development of appropriate bioreactors and models for scale up are essential for practical application of the technology.

Simultaneously, concerns have been expressed about thc implications of this work. In the past, major new technologies have been used intensively for hostile purposes. What is thc challenge that biotechnology poses in this regard'? This review paper looks at the enormous changes in civil society that thc genomics revolution could bring. Against this background, thc growing concerns about its potential misuses have been reviewed. Thc strengths and weaknesses or the Biological and Toxin Weapons Convention (BTWC are then touched upon. The BTWC presently lacks an adequate verification mechanism. Although biotechnology has been used by human beings since prehistoric times (eg. making of bread. cheese. wines its scientific understanding came only in the latter part of the 19th century. Thc decisive turning point in the field came in the 1970s with the advent of genetic engineering. In the military context classical agents like anthrax and toxin remain the threat today. Although thc current level or sophistication for many biological agents is low, there is enormous potential for making more sophisticated weapons. It might be possible to specifically target the genetic makeup of different ethnic groups. The limited varieties of staple crops and the limited strains of modern animals make agriculture particularly open to attack. Another serious possibility is the impact of genomics in neuroscience. With a better understanding of cellular receptor systems and bioregulators, it is not inconceivable that new means would be evolved for disturbing the functions of the nervous system.

    Background: National recommendations to increase school-based physical activity and promote academic success advise incorporating movement into traditional classroom lessons. Classroom-based physical activities have favorable associations with indicators of cognitive functioning, academic behaviors, and academic achievement. Purpose: This study analyzed the Active Science framework, which incorporated school-based physical activity within interactive science classroom lessons. Specifically, the study measured the effects of the Active Science framework on student physical activity levels in the classroom, student learning of science inquiry skills and content knowledge, and student perceptions of physical activity and science. A secondary purpose was to evaluate the teachers' perceptions on the implementation of the framework. Subjects: Participants were 37 Hispanic girls (age=11.1 +/-0.8 yr) in mixed 5th/6th grade science classes in a private, urban middle school. Methods: Physical activity levels of the students during the Active Science framework were measured using pedometers and heart rate monitors. Pre- and post-tests were used to assess the levels of learning achieved by the students in science inquiry skills and content during the Active Science framework. Student perceptions and attitudes toward science and physical activity were measured during student focus groups and pre-post perception surveys. Lesson plan evaluations completed by the teachers and structured interviews provided data on implementation of the framework. Results: Physical activity results showed heart rate (146 +/-9 bpm); maximal heart rate (196 +/-10.6 bpm); time (35 +/-2.5 mins); steps (3050 +/-402.7); calories (99 +/-8.4 kcal); and distance (1.1 +/-0.2 miles) while performing the activity portion of the science lessons were consistent with national recommendations for accumulating school-based physical activity.

    The excavations of Gargaresc started in 1965 and were one of the most important archaeological sites in Tripoli because it includes a period of about 500 years starting from the 1stc. AD was and continuing until the 5th century AD. The Mithraic tomb is one of the most important outlying monuments of Oea, 200 yards south of the western end of Gargaresc oasis, on the left of the Tripoli-Zuara road between kilometers 5 & 6. The tomb is cut in an outcrop of soft sandstone. The wall paintings found were symbolic to the religion of that period; which contained a mixture of older religions and Christian, and presented the interaction between the artistic and religious elements of that time. Several optical, chemical and mineralogical methods were applied to identify the materials, composition and technology of the plasters and mortars, as well as, the pigments used in the tomb. These are: -OP: Optical microscopy was used as the initial examination of polished cross-sections to identify the structure and microstratigraphy of the plasters and mortars as well as the painted layers. -MCT: Micro-chemical tests were used to identify the type of the plasters and mortars- calcium aluminium silicate and water-soluble salt to identify sulphates, chlorides, carbonates, nitrites and nitrates. -SM: Standard methods for chemical analysis to identify the quantitative and qualitative nature of the plasters and mortars and their mixture. -SEM & EDS: Analytical Scanning electron microscope with energy dispersive x-ray analysis system to examine the micrmorphology and determine the chemical composition of the plasters, pigments and the inclusions. -XRD: X-ray powder diffraction to identify the mineralogical composition of the plasters, mortars and pigments. On the bases of all the data obtained, it was possible to establish the nature of the plasters, mortars and their binder. The examination and analysis gave a full picture about the materials and the approximate ratio of amount of

    The food processing industry is the oldest and largest industry using biotechnological processes. Further development of food products and processes based on biotechnology depends upon the improvement of existing processes, such as fermentation, immobilized biocatalyst technology, and production of additives and processing aids, as well as the development of new opportunities for food biotechnology. Improvements are needed in the characterization, safety, and quality control of food materials, in processing methods, in waste conversion and utilization processes, and in currently used food microorganism and tissue culture systems. Also needed are fundamental studies of the structure-function relationship of food materials and of the cell physiology and biochemistry of raw materials.

Individual topics often come up that warrant not only single articles, but collections of assessments, and ERL has published focus issues in key areas of environmental science including: tropical deforestation, wind energy, the Deepwater Horizon oil spill and climate engineering. ERL is currently publishing seven high-quality focus issues in cutting-edge areas such as arctic vegetation dynamics and cryospheric changes. Research letters appearing in ERL have received regular and significant coverage in the wider media, with several major news outlets and agencies choosing to cover ERL research, such as Nature, BBC News, New Scientist, The Guardian, Scientific American, Le Monde and many others. 4.The future community of ERL The process of community support will take many forms at ERL. The journal is growing—we have published the highest number of articles ever in a single volume in 2011 and are looking to continue this growth through into 2012. ERL had an over 50% increase in submissions from 2010 to 2011. One initiative to mark the journal's 5th anniversary was the 'Best articles' collection [1] a nominated compilation of articles showcasing the quality of published work in ERL as well as the subject area breadth. Co-authors of the five winning articles have been awarded free publication in ERL until the end of 2012. We can also see the open access model working, in that our articles are highly downloaded outside of the traditionally strong geographical areas of academia (North America and Western Europe), showing that the journal's readership is geographically diverse with high interest from Asia, South America and Africa. The journal is committed to progress and innovation; coming soon will be a set of new communication tools and online innovations, including: Video abstracts from the start of 2012 (for example, the video commentary published alongside this

  8. Plant Biotechnology: Promises and Challenges

    Full Text Available Development of procedures in cell biology to regenerate plants from single cells in any desired quantity provides the prerequisite for the practical use of plant tissue culture and genetic engineering in crop improvement. Such regenerating cell cultures are used for selection of mutants and for DNA transformation experiments. DNA transfer by means of engineered Ti and Ri plasmids has become an established technique for the rapidly growing list of dicotyledonous plants. Considerable success has also been achieved in making gene transfer techniques independent of cell culture methods. These techniques have given the opportunity to create, characterise and select plant cultivars which cannot be obtained by traditional breeding methods. The exploitation of plant cell cultures for production of pharmaceuticals, natural products of commercial importance and mass propagation of high-value crops by automation, have developed into an important industry with considerable potential for future. This paper discusses the recent advances and applications of plant biotechnology in agriculture and industry and the challenges the still exist.

    2011-01-01

    Full Text Available Great advances in technology produce unique challenges. Every technology also has a dual use, which needs to be understood and managed to extract maximum benefits for mankind and the development of civilization. The achievements of physicists in the mid-20th century resulted in the nuclear technology, which gave us the destructive power of the atomic bomb as also a source of energy. Towards the later part of the 20th century, information technology empowered us with fast, easy and cheap access to information, but also led to intrusions into our privacy. Today, biotechnology is yielding life- saving and life-enhancing advances at a fast pace. But, the same tools can also give rise to fiercely destructive forces. How do we construct a security regime for biology? What have we learnt from the management of earlier technological advances? How much information should be in the public domain? Should biology, or more broadly science, be regulated? Who should regulate it? These and many other ethical questions need to be addressed.

    For the evaluation and interpretation of pharmacokinetic data reliable quantitative determinations are a requirement that can only be met by well-characterized and fully validated analytical methods. To cope with these requirements a method is being established that is based on an integrated and automated fiber-optic biospecific interaction analysis system (FOBIA) for immunoassays. Performance characteristics of this system used in monitoring of recombinant hirudin (CGP 39 393) are presented. Recombinant hirudin is a highly potent and selective inhibitor of human thrombin. Owing to its size and charge, recombinant hirudin is mainly eliminated by glomerular filtration. But only a fraction of the hirudin dose seems to be reabsorbed at the proximal tubule by luminal endocytosis and hydrolyzed by lysosomal enzymes, leaving approximately 50% of the dose to be extracted in the urine. Thus, renal clearance of recombinant hirudin in the absence of renal insufficiency appears to depend primarily on the glomerular filtration rate. During a 3-month i.v. tolerability study in dogs, some of the dogs developed antibodies against recombinant hirudin. The hirudin-antibody complex accumulated in plasma and apparent hirudin plasma concentrations were therefore much higher than expected from single-dose kinetics. Hirudin captured by antibodies showed an extended half-life and the hirudin-antibody complex is still pharmacologically active, as demonstrated by the observed increase in thrombin time. In conclusion, only appropriate analytical methods allow adequate monitoring and pharmacokinetic characterization of biotechnology drugs in biological materials. PMID:8857560

    Full Text Available Cellulases have numerous applications in several industries, including biofuel production, food and feed industry, brewing, pulp and paper, textile, laundry, and agriculture.Cellulose-degrading bacteria are widely spread in nature, being isolated from quite different environments. Cellulose degradation is the result of a synergic process between an endoglucanase, an exoglucanase and a,β-glucosidase. Bacterial endoglucanases degrade ß-1,4-glucan linkages of cellulose amorphous zones, meanwhile exoglucanases cleave the remaining oligosaccharide chains, originating cellobiose, which is hydrolyzed by ß-glucanases. Bacterial cellulases (EC 3.2.1.4 are comprised in fourteen Glycosil Hydrolase families. Several advantages, such as higher growth rates and genetic versatility, emphasize the suitability and advantages of bacterial cellulases over other sources for this group of enzymes. This review summarizes the main known cellulolytic bacteria and the best strategies to optimize their cellulase production, focusing on endoglucanases, as well as it reviews the main biotechnological applications of bacterial cellulases in several industries, medicine and agriculture.

    Magnetic separations have for decades been essential processes in diverse industries ranging from steel production to coal desulfurization. In such settings magnetic fields are used in continuous flow processes as filters to remove magnetic impurities. High gradient magnetic separation (HGMS) has found even broader use in wastewater treatment and food processing. Batch scale magnetic separations are also relevant in industry, particularly biotechnology where fixed magnetic separators are used to purify complex mixtures for protein isolation, cell separation, drug delivery, and biocatalysis. In this review, we introduce the basic concepts behind magnetic separations and summarize a few examples of its large scale application. HGMS systems and batch systems for magnetic separations have been developed largely in parallel by different communities. However, in this work we compare and contrast each approach so that investigators can approach both key areas. Finally, we discuss how new advances in magnetic materials, particularly on the nanoscale, as well as magnetic filter design offer new opportunities for industries that have challenging separation problems.

  18. Biological basis of beam application in biotechnology

    International Nuclear Information System (INIS)

    Heavy particle beams have relatively high value of linear energy transfer (LET), and relative biological effectiveness (RBE). There is a sharp increase in ionization density (LET) in the so-called Bragg peak, close to the end of each track. The LET and RBE may, therefore, be high at the distal edge of the biological target volume. It is well-known that as the LET is increased beyond about 30 keV/um the RBE increases to a peak at 100 to 110 keV/um and then falls. At the same time the oxygen-enhancement ratio (OER) decreases steadily. The reason of these events has a greater chance per unit dose of depositing a certain minimum energy of about 300 eV, that is, 10 to 15 ionizations into each biological target volume of 5 to 10 nm diameter. These biological targets may be pictured as double strands of DNA and histones, 2 or 3 nm in diameter, with a surrounding water sheath of a few nm thick. The drop of RBE with increasing LET past the peak of RBE is due to either overkill or the recombinations of electrons and ions and of chemical radicals in the higher LET track. Large new accelerators have allowed the effects of heavy particle irradiation to be investigated. In biotechnology, radiation methods have found application as tools to explore some basic problems and this aspect of radiation research is likely to expand in the future. (author)

    A survey of 128 biotechnology core facilities has provided data on the finances, services, space requirements, and personnel. An average facility had four full-time personnel and 7.5 major instrument systems, and occupied 969 sq. ft. Average total income was $244,000/year, but annual user fee income was only $125,000. Typically, facilities required substantial institutional support or grants. Cost recovery (user fee income divided by total income) averaged 49%. During the last 5 years user fee income, total income, and cost recovery have increased. In-house charges for protein sequencing and peptide synthesis increased approximately 30%, while oligonucleotide synthesis charges decreased by 74%. The costs (charges corrected for subsidy from non-user fee income) for most services did not significantly change, except that oligonucleotide synthesis costs decreased by 25% in 1992. DNA synthesis had the highest throughout per month (116 samples), followed by amino acid analysis (86 samples) and DNA sequencing (67 samples). Other services averaged from 5 to 60 samples. DNA synthesis and purification were the services used by the greatest number of principal investigators. A number of services including DNA sequencing, mass spectrometry, capillary electrophoresis, RNA synthesis, electroblotting, and carbohydrate analysis have been introduced in the last 3 years. Although these services are characterized by high levels of methods development and non-user runs, they are offered by twice the percentage of facilities as in 1989, and are increasingly contributing to facility income.

    2012-04-01

    The purpose of this investigation was to explore students' epistemic beliefs and conceptual understanding of biotechnology. Epistemic beliefs can influence reasoning, how individuals evaluate information, and informed decision making abilities. These skills are important for an informed citizenry that will participate in debates regarding areas in science such as biotechnology. We report on an in-depth case study analysis of three undergraduate, non-science majors in a biotechnology course designed for non-biochemistry majors. We selected participants who performed above average and below average on the first in-class exam. Data from multiple sources—interviews, exams, and a concept instrument—were used to construct (a) individual profiles and (b) a cross-case analysis of our participants' conceptual development and epistemic beliefs from two different theoretical perspectives—Women's Ways of Knowing and the Reflective Judgment Model. Two independent trained researchers coded all case records independently for both theoretical perspectives, with resultant initial Cohen's kappa values above .715 (substantial agreement), and then reached consensus on the codes. Results indicate that a student with more sophisticated epistemology demonstrated greater conceptual understandings at the end of the course than a student with less sophisticated epistemology, even though the latter performed higher initially. Also a student with a less sophisticated epistemology and low initial conceptual performance does not demonstrate gains in their overall conceptual understanding. Results suggest the need for instructional interventions fostering epistemological development of learners in order to facilitate their conceptual growth.

    The estimate of absorbed dose to individual organs of a space crewmember is affected by the geometry of the anatomical model of the astronaut used in the radiation transport calculation. For astronaut dosimetry, NASA currently uses the computerized anatomical male (CAM) and computerized anatomical female (CAF) stylized phantoms to represent astronauts in its operational radiation dose analyses. These phantoms are available in one size and in two body positions. In contrast, the UF Hybrid Adult Male and Female (UFHADM and UFHADF) phantoms have organ shapes based on actual CT data. The surfaces of these phantoms are defined by non-uniform rational B-spline surfaces, and are thus flexible in terms of body morphometry and extremity positioning. In this study, UFHADM and UFHADF are scaled to dimensions corresponding to 5th, 50th, and 95th percentile (PCTL) male and female astronauts. A ray-tracing program is written in Visual Basic 2008, which is then used to create areal density maps for dose points corresponding to various organs within the phantoms. The areal density maps, along with appropriate space radiation spectra, are input into the NASA program couplet HZETRN/BRYNTRN, and organ doses are calculated. The areal density maps selected tissues and organs of the 5th, 50th, and 95th PCTL male and female phantoms are presented and compared. In addition, the organ doses for the 5th, 50th, and 95th PCTL male and female phantoms are presented and compared to organ doses for CAM and CAF.

    Full Text Available Modifying cryopreservation protocols may be seen as a way to simplify cryobanking procedure and increase satisfying outcomes. The aim of the study was to evaluate the influence of slow cooling protocol and vitrification on IVF outcomes using embryos preserved in the 5th or 6th day after oocyte retrieval. The study compared 2 groups of human embryos underwent slow cooling protocol (n=189 and vitrification (n=58. All embryos were cryopreserved in the 5th or 6th day after oocyte retrieval. Pre- and postfreezing embryo evaluation was performed in 2 or 3 steps scale, respectively. The study evaluates the effectiveness of two freezing methods and influence of the freezing day, pre- and postfreezing embryo grading on clinical pregnancy rate. Study showed higher pregnancy rate after vitrification (50.4% than slow cooling protocol (25.9%. Significantly higher pregnancy rate was observed, when embryo preserved in the 5th day after oocyte retrieval (50.3% than in the 6th day (22.7%. Postfreezing embryos evaluation showed that high quality blastocysts gave nearly four times better pregnancy outcomes than the ones evaluated as poor quality, and three times better than the ones evaluated as moderate. Prospective trials are needed to evaluate pregnancy and neonatal outcomes after vitrification. The number of controlled studies concerning vitrification has not been large enough, yet.

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

    2013-01-01

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

    2001-01-01

    The direct detection of organic biomarkers for living or fossil microbes on Mars by an in situ instrument is a worthy goal for future lander missions. Several new and innovative biotechnology approaches are being explored. Firstly we have proposed an instrument based on immunological reactions to specific antibodies to cause activation of fluorescent stains. Antibodies are raised or acquired to a variety of general and specific substances that might be in Mars soil. These antibodies are then combined with various fluorescent stains and applied to micron sized numbered spots on a small (2-3 cm) test plate where they become firmly attached after freeze drying. Using technology that has been developed for gene mining in DNA technology up to 10,000 tests per square inch can now be applied to a test plate. On Mars or the planet/moon of interest, a sample of soil from a trench or drill core is extracted with water and/or an organic solvent and ultrasonication and then applied to the test plate. Any substance, which has an antibody on the test plate, will react with its antibody and activate its fluorescent stain. At the moment a small UV light source will illuminate the test plate, which is observed with a small CCD camera, although other detection systems will be applied. The numbered spots that fluoresce indicate the presence of the tested-for substance, and the intensity indicates relative amounts. Furthermore with up to a thousand test plates available false positives and several variations of antibody can also be screened for. The entire instrument can be quite small and light, on the order of 10 cm in each dimension. A possible choice for light source may be small UV lasers at several wavelengths. Some of the wells or spots can contain simply standard fluorescent stains used to detect live cells, dead cells, DNA, etc. The stains in these spots may be directly activated, with no antibodies being necessary. The proposed system will look for three classes of

  12. Applications of Protein Hydrolysates in Biotechnology

    Science.gov (United States)

    Pasupuleti, Vijai K.; Holmes, Chris; Demain, Arnold L.

    By definition, protein hydrolysates are the products that are obtained after the hydrolysis of proteins and this can be achieved by enzymes, acid or alkali. This broad definition encompasses all the products of protein hydrolysis - peptides, amino acids and minerals present in the protein and acid/alkali used to adjust pH (Pasupuleti 2006). Protein hydrolysates contain variable side chains depending on the enzymes used. These side chains could be carboxyl, amino, imidazole, sulfhydryl, etc. and they may exert specific physiological roles in animal, microbial, insect and plant cells. This introductory chapter reviews the applications of protein hydrolysates in biotechnology. The word biotechnology is so broad and for the purpose of this book, we define it as a set of technologies such as cell culture technology, bioprocessing technology that includes fermentations, genetic engineering technology, microbiology, and so on. This chapter provides introduction and leads to other chapters on manufacturing and applications of protein hydrolysates in biotechnology.

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

    2015-01-01

    Extracellular electron transfer (EET) is a type of microbial respiration that enables electron transfer between microbial cells and extracellular solid materials, including naturally-occurring metal compounds and artificial electrodes. Microorganisms harboring EET abilities have received considerable attention for their various biotechnological applications, in addition to their contribution to global energy and material cycles. In this review, current knowledge on microbial EET and its application to diverse biotechnologies, including the bioremediation of toxic metals, recovery of useful metals, biocorrosion, and microbial electrochemical systems (microbial fuel cells and microbial electrosynthesis), were introduced. Two potential biotechnologies based on microbial EET, namely the electrochemical control of microbial metabolism and electrochemical stimulation of microbial symbiotic reactions (electric syntrophy), were also discussed.

    Gold, E Richard; Castle, David; Cloutier, L Martin; Daar, Abdallah S; Smith, Pamela J

    2002-08-01

    Although never uncontroversial, intellectual property rights in biotechnological innovation are once more the focus of intense debate. The debate has yet to reach any result, largely because of several important errors in the way that various disciplines approach it. These errors include making assumptions without empirical basis and conflating various intellectual property regimes. What is needed is a transdisciplinary integrated method to correct these errors. Such a method can be implemented through the construction of alternative models of intellectual property protection designed to balance the various social, ethical and economic constraints that affect biotechnology.

  18. Biotechnology and medicine of the future

    International Nuclear Information System (INIS)

    The practice of biology and medicine has been revolutionized during the past ten years by the advent of three biotechnologies-recombinant DNA techniques, the monoclonal antibody technology, and the development of microchemical instrumentation, machines that permit the rapid and effective synthesis and sequence analysis of proteins and genes. In this article, these powerful biotechnologies are discussed, with particular emphasis on microchemical instrumentation, a major focus of my efforts for the past 15 years. The author also discusses two fundamental problems in modern medicine that are being explored in the laboratory using these techniques-genetic engineering of the nervous system and the mapping and sequencing of the human genome

  19. Irradiation experiments of 3rd, 4th and 5th fuel assemblies by an in-pile gas loop, OGL-1

    International Nuclear Information System (INIS)

    Three irradiation experiments for 3rd, 4th and 5th fuel assemblies which had been composed of VHTR reference coated particle fuels and graphite components were carried out by an in-pile gas loop, OGL-1 during 1979 and 1982. The main purposes of these experiments were to study on bowing of the fuel rod by irradiation for the 3rd fuel assembly, to study on fuel behavior under relatively low burnup irradiation for the 4th fuel assembly, and to study on fuel behavior up to full burnup of VHTR design for the 5th fuel assembly. For understanding in-pile fuel behavior, fractional releases of fission gases from each fuel assembly were estimated by measuring the fission gas concentrations in the primary loop of OGL-1. The post-irradiation examination (PIE) was carried out extensively on the fuel block, the fuel rods and the fuel compacts in Tokai Hot Laboratory. Also, made were the measurements of metallic fission product distributions in the fuel assemblies and the fuel rods. The results in these experiments were given as follows ; bowing of the fuel rod in the 3rd fuel assembly was 0.7 mm, but integrity of the rod was kept under irradiation. Fractional release of the fission gas from the 4th fuel assembly remained in the order of 10-7 during irradiation, suggesting that the fuel performance was excellent. The fractional release from the 5th fuel assembly, on the other hand, was in the order of 10-5 which was the same level in the VHTR design. (author)

    1984-11-01

    The purpose of this study is to identify and quantify potential energy savings available through the development and application of biotechnologies. This information is required in support of ECUT research planning efforts as an aid in identifying promising areas needing further consideration and development. It is also intended as background information for a companion ECUT study being conducted by the National Academy of Science to evaluate the use of bioprocessing methods to conserve energy. Several studies have been conducted recently to assess the status and implications of the development of biotechnology. The Office of Technology Assessment (OTA) considered institutional, economic, and scientific problems and barriers. The National Science Foundation sponsored a study to examine regulatory needs for this new and expanding technology. Somewhat in contrast to these studies, this report covers principally the technical issues. It should be emphasized that the practicality of many developments in biotechnology is not evaluated solely on the basis of energy considerations. Bioprocesses must often compete with well-established coal, petroleum, and natural gas technologies. A complete evaluation of the technical, economical, and ecological impacts of the large-scale applications discussed in this report is not possible within the scope of this study. Instead, this report assesses the potential of biotechnology to save energy so that research into all aspects of implementation will be stimulated for those industries with significant energy savings potential. 92 references, 6 figures, 24 tables.

  1. Use of biotechnology in flax germplasm development

    International Nuclear Information System (INIS)

    Full text: Andro, CDC Normandy, CDC Triffid, and Linola 989 are examples of flax varieties that have been developed through the application of biotechnology. Somaclonal variation, cell selection, haploid breeding, mutagenesis, genetic engineering and molecular marker development are all being employed in flax germplasm development. Tissue culture techniques such as somaclonal variation (CDC Normandy) and cell selection (Andro) have been successful, but the greatest potential for the use of tissue culture methodology is the application of haploid breeding. While a number of groups worldwide have had limited success in producing doubled haploid plants from anther and/or microspore culture [Chen et al. 1998, Plant Breeding 117: 463; Friedt et al. 1995, Plant Breeding 114: 322; Nichterlein and Friedt 1993, Plant Cell Rep. 12: 426], the frequency of regeneration has limited its application in variety development. Several groups are currently using anther culture within their breeding programs, but the ultimate success of haploid breeding will undoubtedly depend on developing an efficient microspore-derived system for doubled haploid production. Perhaps the most successful technique to date, in terms of germplasm development, has been the use of mutagenesis. The Linola types [Dribnenki et al. 1996, Can. J. Plant Sci. 76:329; Dribnenki and Green 1995, Can. J. Plant Sci. 75: 201], have already been released, and other modified oil types are currently being developed [Saeidi and Rowland 1997, J. Hered. 88: 466; Ntiamoah et al. 1995, Crop Sci. 35: 148]. Additional traits being investigated in mutagenized populations include seed colour, reduced levels of anti nutritional factors in seed, increased nutraceutical content, and traits of agronomic interest. For example, screening of an EMS-treated population of McGregor flax at the Crop Development Centre identified three mutant lines which had greatly reduced levels of cyanogenic glucosides. Flax has proven to be amenable to

    Full Text Available Objectives: To evaluate the prevalence of methylphenidate (MPH use among 5th and 6th year medical students, to discriminate MPH use with and without medical indication, and to correlate MPH use with alcohol intake. Methods: This is a cross-sectional study in which medical students were invited to answer a questionnaire to evaluate academic and socioeconomic status, MPH use patterns, and attitudes towards neuroenhancing drugs. The Alcohol Use Disorders Identification Test (AUDIT was used to assess alcohol intake; a score ≥ 8 suggests potentially hazardous alcohol use. Results: Fifty-two participants (34.2% had already used MPH, of which 35 (23.02% had used it without medical indication. The number of 6th year students who had used MPH was more than twice higher than that of their 5th year counterparts (32.89 vs. 13.15%, respectively; p = 0.004. Also, 43.6% (p = 0.031 of the users of MPH had an AUDIT score ≥ 8; 33.3% (p = 0.029 of non-medical users of MPH had an AUDIT score ≥ 8. Conclusions: In this study, the use of MPH without medical indication was prevalent. Our findings also confirmed the association between non-medical use of MPH and potentially hazardous alcohol use.

  3. Effects of blood lead levels on airflow limitations in Korean adults: Findings from the 5th KNHNES 2011

    International Nuclear Information System (INIS)

    This study aimed to examine whether blood levels of heavy metals, such as lead, mercury and cadmium, are related with pulmonary function in Korean adults. This investigation included 870 Korean adults (≥40 years) who received pulmonary function testing in the Korea National Health and Nutrition Examination Survey (KNHANES) V-2, 2011. Data of blood levels of heavy metals, pulmonary function tests and anthropometric measurements were acquired. Blood lead levels showed inverse correlations with the FEV1/FVC ratio before (r=−0.276, p<0.001) and after adjustment of multiple compounding factors (r=−0.115, p=0.001). A logistic multiple regression analysis revealed that blood lead levels were a significant influencing factor for the FEV1/FVC ratio (β=−0.017, p=0.001, adjusted R2=0.267). The odds ratios (ORs) for the FEV1/FVC ratio were significantly lower in the highest tertile group of the blood lead levels than in the lowest tertile group in Model 1 (OR=0.007, 95% CI=0.000−0.329) and Model 2 (OR=0.006, 95% CI=0.000−0.286). These findings imply that environmental exposure to lead might be an important factor that may cause airflow limitations in Korean adults. - Highlights: • Blood lead levels showed inverse correlations with the FEV1/FVC ratio. • Blood lead level was a significant influencing factor for the FEV1/FVC ratio. • ORs for FEV1/FVC were lower in the highest blood lead group than in the lowest group. • Environmental exposure to lead might be an important factor for airflow limitations

    This study aimed to examine whether blood levels of heavy metals, such as lead, mercury and cadmium, are related with pulmonary function in Korean adults. This investigation included 870 Korean adults (≥40 years) who received pulmonary function testing in the Korea National Health and Nutrition Examination Survey (KNHANES) V-2, 2011. Data of blood levels of heavy metals, pulmonary function tests and anthropometric measurements were acquired. Blood lead levels showed inverse correlations with the FEV{sub 1}/FVC ratio before (r=−0.276, p<0.001) and after adjustment of multiple compounding factors (r=−0.115, p=0.001). A logistic multiple regression analysis revealed that blood lead levels were a significant influencing factor for the FEV{sub 1}/FVC ratio (β=−0.017, p=0.001, adjusted R{sup 2}=0.267). The odds ratios (ORs) for the FEV{sub 1}/FVC ratio were significantly lower in the highest tertile group of the blood lead levels than in the lowest tertile group in Model 1 (OR=0.007, 95% CI=0.000−0.329) and Model 2 (OR=0.006, 95% CI=0.000−0.286). These findings imply that environmental exposure to lead might be an important factor that may cause airflow limitations in Korean adults. - Highlights: • Blood lead levels showed inverse correlations with the FEV{sub 1}/FVC ratio. • Blood lead level was a significant influencing factor for the FEV{sub 1}/FVC ratio. • ORs for FEV{sub 1}/FVC were lower in the highest blood lead group than in the lowest group. • Environmental exposure to lead might be an important factor for airflow limitations.

    computers and TeX has not changed this, and likely never will. Although Vince's research efforts are usually focused on problems that can be tackled using mathematical analysis, he has had a pronounced influence on numerical studies in general relativity. Part of this is the result of his extensive numerical studies of cosmological spacetimes. Equally important is the mathematical work he has done on the constraint equations and on choices of gauge; these set the stage for efficient numerical investigations of gravitational systems. In addition, Vince's influence on numerical relativity is felt through the work of his students, including that of Ed Seidel and Roger Ove. While most of Vince's work deals with questions arising in classical physics, he has throughout his career thought deeply about quantum physics as well. This interest, in addition to leading to early work on quantized gravitational perturbations and quantum linearization stabilities and to later work on explicit solutions of the Wheeler-DeWitt equation, has been an important motivation for Vince's extensive studies of Hamiltonian reduction of the Einstein system to its true degrees of freedom. One of the bonuses of a successful scientific research career is the opportunity for travel to many corners of the world. In Vince's case, one of those corners has been Africa. Originally visiting there about ten years ago to serve as a reader for a PhD student in Cameroon, Vince quickly fell in love with Africa. He has become an ardent big game hunter, and visits roughly every year to go on safari in such places as Zimbabwe, Cameroon and Tanzania. In many ways, Vince's great success on African safari mirrors his spectacular success on spacetime safari. We can read about his African safaris at the website http://pantheon.yale.edu/~vem3/safari to learn the details of how he came to have this exotic interest. To read about Vince's spacetime safaris, there is no better source than in his papers. Vince has told his friends

    Biotechnology has been used extensively in the development of vaccines for aquaculture. Modern molecular methods such as polymerase chain reaction (PCR), cloning and microarray analysis have facilitated antigen discovery, construction of novel candidate vaccines, and assessments of vaccine efficacy, mode of action, and host response. This review focuses on DNA vaccines for finfish to illustrate biotechnology applications in this field. Although DNA vaccines for fish rhabdoviruses continue to show the highest efficacy, DNA vaccines for several other viral and bacterial fish pathogens have now been proven to provide significant protection against pathogen challenge. Studies of the fish rhabdovirus DNA vaccines have elucidated factors that affect DNA vaccine efficacy as well as the nature of the fish innate and adaptive immune responses to DNA vaccines. As tools for managing aquatic animal disease emergencies, DNA vaccines have advantages in speed, flexibility, and safety, and one fish DNA vaccine has been licensed.

    The biotechnology/materials interaction dates back 3.5 billion years, yet today offers novel challenges for human creativity. The materials cycle practiced by microorganisms is compared to that recently practiced by humans. The processes of the biotechnology materials cycle are biogenesis, bioleaching, biofouling, biocorrosion, biodeterioration, and bioaccumulation. Each process is examined for mechanisms, scale of effect, and opportunity for creative human intervention or utilization. More than 50 of our metallic elements are bio-processed in nature. A like number of biogenic materials have been identified, with some at production rates of trillions of kg per annum (p.a.). Microorganisms can substitute for energy, capital, and labor. Over the eons, microorganisms have gained special attributes that now offer creative humans a new era of partnership in materials processing.

    Full Text Available The way in which Paul exercises his authority in the Letter to Philemon has been studied from various angles, but as far as could be determined, the reception of this aspect of his letter by its interpreters in the fourth and 5th centuries CE. has not yet received much attention. Accordingly, this aspect is addressed in this study. The views of the following six interpreters are discussed (in chronological order: Ambrosiaster, Jerome, Pelagius, John Chrysostom, Theodore of Mopsuestia, and Theodoret of Cyrus. It is shown that each of them has his own view in this regard, but that two general trends can nevertheless be identified: Firstly, all of these writers accept that Paul had authority over Philemon; and secondly, the commendable way in which Paul exercised this authority is a regular theme in their works.Keywords: Letter to Philemon, Church Fathers, Authority

    Full Text Available Physical inactivity is a growing problem among children, particularly school-aged youth. Research suggests children are especially prone to inactivity in the summer months when access to structured school-time and extra-curricular activities is reduced. Community programs like residential summer camps offer an excellent environment for engaging children in enjoyable physical activities while also helping them learn to be more physically active when they return home. Pre-existing attitudes often influence how much change a program inspires in an individual. The purpose of this study was to explore 4th, 5th, and 6th grade summer camp participants’ attitudes towards physical activity. Results of this study indicate that youth have a fairly neutral, though positive, attitude towards physical activity and that parental support of physical activity is still extremely important, even at this age. Campers also indicated relatively high intentions to remain physically active in the two weeks after the camp ended

    Pakistan is endued with 185 billion tons colossal reserves of coal, but only 7.89 % of the country total energy requirements are met by coal. Most of the Pakistani coal reserves are sub-bituminous or lignitic in nature and contain 3-12 % sulphur. Existence of sulphur compounds in coal limits its industrial application due to environmental as well as technical problems. However, coal biotechnology can emerge as panacea for upgrading the huge reserves of coal in Pakistan. In general, coal biotechnology refers to biodesulphurization, biosolubilization and biogasification of coal. NIBGE has long term interests in the field of coal bioprocessing for tapping prime resources of indigenous coal. In NIBGE, lab scale experiments for coal biodesulphurization led to 90% efficiency in sulphur removal. Heap leaching was also carried out at the level of 10 and 20 tons coal heaps with 60% sulphur removal efficiency. Furthermore, a prototype of 300 tons coal heap was set up with a local cement industry and 75% microbial desulphurization was achieved. The league of indigenously isolated chemolithotrophic bacteria was involved in coal desulphurization. On the other side, for making the best use of 175 billion tons of low rank coal reserves, coal biosolubilization and subsequent biogasification is being projected. Consequently, beneficiated coal through biotechnology is supposed to contribute in energy mix of Pakistan for providing electricity requirements of the country and saving huge oil import bills.

    2008-01-01

    In keeping with the definition that biotechnology is really no more than a name given to a set of techniques and processes, the authors apply some set of fuzzy techniques to chemical industry problems such as finding the proper proportion of raw mix to control pollution, to study flow rates, to find out the better quality of products. We use fuzzy control theory, fuzzy neural networks, fuzzy relational equations, genetic algorithms to these problems for solutions. When the solution to the problem can have certain concepts or attributes as indeterminate, the only model that can tackle such a situation is the neutrosophic model. The authors have also used these models in this book to study the use of biotechnology in chemical industries. This book has six chapters. First chapter gives a brief description of biotechnology. Second chapter deals will proper proportion of mix of raw materials in cement industries to minimize pollution using fuzzy control theory. Chapter three gives the method of determination of te...

The national programs of the leading countries of the world, it is one of the priority sectors, reflecting the level of the socio-economic condition of the society. Biotechnology is now successfully solves such vital tasks as providing food, the establishment of effective medicaments, obtaining fuel based on renewable raw materials, maintaining ecological balance, conservation of biological resources of the Earth. The development of agriculture in modern conditions is impossible without agricultural biotechnology. It is directly related to viticulture. Choosing an object of an integrated system (embryos, apical meristem, axillary buds, it is possible to clone plants, i.e. produce plants identical to the original. If the same as the object to use isolated cells or protoplasts, in this case, there will most likely altered versions, creating diversity for the breeder. Genetic engineering – the science of younger, since the establishment of the first chimeric DNA molecule. The origin of genetic engineering is rooted in the development of molecular genetics, biochemistry. These technologies, undoubtedly progressive, but their biological safety is still insufficiently explored and is a danger to all life on Earth. The leading Western powers carried out strict control over the introduction of transgenic crop plants, as they are in agrocenosis new biological risks that may adversely affect the plants, animals and humans.

  5. Biotechnology for uranium extraction and environmental control

    International Nuclear Information System (INIS)

    India is looking forward to augmenting mining and extraction of uranium mineral for its nuclear energy needs. Being a radio-active mineral, mining and processing of uranium ore deposits need be carried out in an environmentally acceptable fashion. In this respect, a biotechnological approach holds great promise since it is environment-friendly, cost-effective and energy-efficient. There are several types of microorganisms which inhabit uranium ore bodies and biogenesis plays an important role in the mineralisation and transport of uranium-bearing minerals under the earth's crust. Uranium occurrences in India are only meagre and it becomes essential to tap effectively all the available resources. Uraninite and pitchblende occurring along with sulfide mineralisation such as pyrite are ideal candidates for bioleaching. Acidithiobacillus ferrooxidans present ubiquitously in the ore deposits can be isolated, cultured and utilised to bring about efficient acidic dissolution of uranium. Many such commercial attempts to extract uranium from even lean ores using acidophilic autotrophic bacteria have been made in different parts of the world. Anaerobes such a Geobacter and Sulfate Reducing Bacteria (SRB) can be effectively used in uranium mining for environmental control. Radioactive uranium mined wastes and tailing dumps can be cleaned and protected using microorganisms. In this lecture use of biotechnology in uranium extraction and bioremediation is illustrated with practical examples. Applicability of environment-friendly biotechnology for mining and extraction of uranium from Indian deposits is outlined. Commercial potentials for bioremediation in uranium-containing wastes are emphasised. (author)

  6. New biotechnological procedures in swine reproduction

    2002-01-01

    Full Text Available New biotechnological procedures and the use of hormones in swine breeding are aimed at increasing the number of piglets in the litter. In small herds and groups, selected sows with 16 mammary complexes (tits can yield up to 32 piglets, or porkers, per year per sow. In order to achieve such reproduction results, special, individual stalls for sow deliveries are used, in addition to biotechnological methods, with a warm core and floor heating, phased diet and clean facilities. The ovulation value in swine is determined by their genetic and paragenetic effects, and it is often provoked and increased with injections and preparations for superovulation. However, the results vary, since any administration of hormone injecions can reduce the reproductive cycle, shorten the duration of estrus, or disrupt the work of ovaries and create cystic follicles. The use of follicle-stimulating hormones in quantities up to 1000 IU per animal for the induction and synchronization of estrus has become customary for sows and gilts, as well as the use of prostaglandins, the use of GnRH for increasing ovulation in swine and increasing the number of follicles >4 mm in diameter in the implementation of new biotechnologies in swine breeding, increases the number of ovulations and fertility in swine. In this way, reproduction is raised to the highest possible level, and artificial insemination of sows has 12 separate rules which enable better and more successful artificial insemination of sows.

    Surveillance testing for reactor vessel materials is performed in order to evaluate the irradiation embrittlement due to neutrons during operation and set the condition of safe operation of nuclear reactor. The 5th surveillance testing was performed completely by Korea Atomic Energy Research Institute at Daejeon after the capsule was transported from Yonggwang site including its removal from reactor. Fast neutron fluences for capsules were calculated and various testing including mechanical and chemistry analysis were performed in order to evaluate the integrity of Yonggwang unit 2 reactor vessel during the operation until life time. The evaluation results are as follows; Fast neutron fluences for capsules U, V, X, W and Y are 5.777E+18, 1.5371E+19, 3.7634E+19, 4.3045E+19, and 4.8662E+19n/cm{sup 2}, respectively. The bias factor, the ratio of calculation/measurement, was 0.953 for the 1st through 5th testing and the calculational uncertainty,7.2% satisfied the requirement of USNRC Reg.Guide 1.190, 20%. The best estimated neutron fluence for reactor vessel inside surface was 1.659E+19n/cm{sup 2} based on the end of 13th fuel cycle and it was predicted that the fluences of vessel inside surface at 32, 48, 56 and 64EFPY would reach 3.625E+19, 5.293E+19, 6.127E+19 and 6.960E+19n/cm{sup 2} based on the current calculation. The result through this analysis for Yonggwang unit 2 showed that there would be no problem for the Pressurized Thermal Shock(PTS) during the operation until design life.

    Background Two different Th2 subsets have been defined recently on the basis of IL-5 expression – an IL-5+Th2 subset and an IL-5−Th2 subset in the setting of allergy. However, the role of these newly described CD4+ T cells subpopulations has not been explored in other contexts. Methods To study the role of the Th2 subpopulation in a chronic, tissue invasive parasitic infection (lymphatic filariasis), we examined the frequency of IL-5+IL-4+IL-13+ CD4+ T cells and IL-5−IL-4 IL-13+ CD4+ T cells in asymptomatic, infected individuals (INF) and compared them to frequencies (Fo) in filarial-uninfected (UN) individuals and to those with filarial lymphedema (CP). Results INF individuals exhibited a significant increase in the spontaneously expressed and antigen-induced Fo of both Th2 subpopulations compared to the UN and CP. Interestingly, there was a positive correlation between the Fo of IL-5+Th2 cells and the absolute eosinophil and neutrophil counts; in addition there was a positive correlation between the frequency of the CD4+IL-5−Th2 subpopulation and the levels of parasite antigen – specific IgE and IgG4 in INF individuals. Moreover, blockade of IL-10 and/or TGFβ demonstrated that each of these 2 regulatory cytokines exert opposite effects on the different Th2 subsets. Finally, in those INF individuals cured of infection by anti-filarial therapy, there was a significantly decreased Fo of both Th2 subsets. Conclusions Our findings suggest that both IL-5+ and IL-5−Th2 cells play an important role in the regulation of immune responses in filarial infection and that these two Th2 subpopulations may be regulated by different cytokine-receptor mediated processes.

    Transgenic Bt cotton has been planted in China since 1997 and, in 2009, biosafety certificates for the commercial production of Bt rice and phytase corn were issued by the Chinese government. The public attitude in China toward agricultural biotechnology and genetically modified (GM) crops and foods has received considerable attention worldwide. We investigated the attitudes of consumers, Bt cotton farmers and scientists in China regarding GM crops and foods and the factors influencing their attitudes. Data were collected using interview surveys of consumer households, farmer households and scientists. A discrete choice approach was used to elicit the purchase intentions of the respondents. Two separate probit models were developed to examine the effect of various factors on the choices of the respondents. Bt cotton farmers had a very positive attitude because Bt cotton provided them with significant economic benefits. Chinese consumers from developed regions had a higher acceptance and willingness to pay for GM foods than consumers in other regions. The positive attitude toward GM foods by the scientific community will help to promote biotechnology in China in the future. Our survey emphasized that educational efforts made by government officials, the media and scientists can facilitate the acceptance of GM technology in China. Further educational efforts will be critical for influencing consumer attitudes and decisions of government agencies in the future. More effective educational efforts by government agencies and public media concerning the scientific facts and safety of GM foods would enhance the acceptance of GM crops in China.

    Full Text Available The marine environment covers almost three quarters of the planet and is where evolution took its first steps. Extremophile microorganisms are found in several extreme marine environments, such as hydrothermal vents, hot springs, salty lakes and deep-sea floors. The ability of these microorganisms to support extremes of temperature, salinity and pressure demonstrates their great potential for biotechnological processes. Hydrolases including amylases, cellulases, peptidases and lipases from hyperthermophiles, psychrophiles, halophiles and piezophiles have been investigated for these reasons. Extremozymes are adapted to work in harsh physical-chemical conditions and their use in various industrial applications such as the biofuel, pharmaceutical, fine chemicals and food industries has increased. The understanding of the specific factors that confer the ability to withstand extreme habitats on such enzymes has become a priority for their biotechnological use. The most studied marine extremophiles are prokaryotes and in this review, we present the most studied archaea and bacteria extremophiles and their hydrolases, and discuss their use for industrial applications.

The positive attitude toward GM foods by the scientific community will help to promote biotechnology in China in the future. Our survey emphasized that educational efforts made by government officials, the media and scientists can facilitate the acceptance of GM technology in China. Further educational efforts will be critical for influencing consumer attitudes and decisions of government agencies in the future. More effective educational efforts by government agencies and public media concerning the scientific facts and safety of GM foods would enhance the acceptance of GM crops in China.

    Transgenic Bt cotton has been planted in China since 1997 and, in 2009, biosafety certificates for the commercial production of Bt rice and phytase corn were issued by the Chinese government. The public attitude in China toward agricultural biotechnology and genetically modified (GM) crops and foods has received considerable attention worldwide. We investigated the attitudes of consumers, Bt cotton farmers and scientists in China regarding GM crops and foods and the factors influencing their attitudes. Data were collected using interview surveys of consumer households, farmer households and scientists. A discrete choice approach was used to elicit the purchase intentions of the respondents. Two separate probit models were developed to examine the effect of various factors on the choices of the respondents. Bt cotton farmers had a very positive attitude because Bt cotton provided them with significant economic benefits. Chinese consumers from developed regions had a higher acceptance and willingness to pay for GM foods than consumers in other regions. The positive attitude toward GM foods by the scientific community will help to promote biotechnology in China in the future. Our survey emphasized that educational efforts made by government officials, the media and scientists can facilitate the acceptance of GM technology in China. Further educational efforts will be critical for influencing consumer attitudes and decisions of government agencies in the future.

    Studies assign a tremendous growth potential related to biotechnology. However, the predicted proportion of biotechnological manufactured products in the chemical industry for the year 2010 by 20 % will more likely remain by today's 5 %. The study deals with the question why biotechnological products are currently established at the market in the obvious slow way. Therefore, the current constraints and existing respectively new incentive instruments referring to the white (industrial) biotechnology are analyzed to focus on the promotion of the development and application of environmentally friendly biotechnology products and methods. In addition to a search concerning environmental relevance and further development of white biotechnology, the postulated constraints and incentives as well as new promotions are discussed with the help of expert interviews. On the basis of a preliminary study - after further discussion with experts - concrete proposals on improvements related to an ongoing establishment of biotechnology will be derived. Based on case studies (2nd generation biofuels, polyhydroxybutyrate as biopolymer and phytase as an animal feed additive), the practical effects and specific conditions to incentives, from the perspective of biotechnological processes and environmentally friendly products are investigated. Overall, about 40 activities were recommended, which could be assigned to areas of direct government incentives (tax policy/subsidies, subsidies, education and research policy, basic political conditions, government demand and information policy/consumer intelligence) as well as non-governmental incentives (knowledge transfer and cooperation, organisation-related policy, capital market financing).

    2009-07-01

    This work presents the precise identification of triacylglycerols (TAGs) extracted from archaeological samples using a methodology based on nanoelectrospray and Fourier transform mass spectrometry. The archaeological TAG identification needs adapted sample preparation protocols to trace samples in advanced degradation state. More precisely, the proposed preparation procedure includes extraction of the lipid components from finely grinded ceramic using dichloromethane/methanol mixture with additional ultrasonication treatment, and TAG purification by solid phase extraction on a diol cartridge. Focusing on the analytical approach, the implementation of "in-house" species-dependent TAG database was investigated using MS and InfraRed Multiphoton Dissociation (IRMPD) MS/MS spectra; several vegetal oils, dairy products and animal fats were studied. The high mass accuracy of the Fourier transform analyzer ([Delta]m below 2.5 ppm) provides easier data interpretation, and allows distinction between products of different origins. In details, the IRMPD spectra of the lithiated TAGs reveal fragmentation reactions including loss of free neutral fatty acid and loss of fatty acid as [alpha],[beta]-unsaturated moieties. Based on the developed preparation procedure and on the constituted database, TAG extracts from 5th century BC to 4th century AD Olbia lamps were analyzed. The structural information obtained succeeds in identifying that bovine/ovine fats were used as fuel used in these archaeological Olbia lamps.

    The posterior silk gland (PSG) of silkworm is an important organ where fibroin is synthesized and secreted exclusively.Because fibroin constitutes 75-80% of the silk filament, the mechanism governing fibroin secretion, quality and yield of cocoon can be elucidated by the study on the PSG. Using two-dimensional gel electrophoresis (2-DE) and image analysis system, the changes in the protein composition in the PSG cell were investigated on the day 1 (D1) and day 4 (D4) in the 5th instar stage from five different strains of silkworm (Bombyx mori). While differences at protein level between days and strains were far less than those observed at the gene level using EST analysis. The change trends in protein composition from D1 to D4 were diverse among the different strains. The results suggest that the secretion of fibroin is regulated by multiple proteins. The site of regulation and the proteins responsible for the regulation vary with the strain, which leads to differences between strains in the capacity of fibroin secretion in the PSG cell.

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

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

    2005-04-01

    Full Text Available Antimicrobial resistance is one of the most urgent problems in medicine nowadays. The purpose of the study was to investigate the microorganisms resistant to first-line antimicrobials, including gram-positive cocci, particularly the methicillin-resistant Staphylococcus aureus and coagulase-negative Staphylococci, the major agents of nosocomial infections. Owing to the multi-resistance of these agents, precise diagnosis of the methicillin resistance of Staphylococci is of greatest clinical importance. It is not enough to use only conventional microbiological diagnostic methods. Biotechnological methods should be also involved. In our studies, the following methicillin resistance identification methods were used: the disk diffusion method, detection of the mecA gene by PCR, E-test and Slidex MRSA test. For molecular typing, PFGL, RAPD tests and detection of the coa gene were used. All the MRS strains were multiresistant to antibacterials. No vancomycine resistance was registered.

  20. APPLICATIONS OF BIOTECHNOLOGY IN DEVELOPMENT OF BIOMATERIALS: NANOTECHNOLOGY AND BIOFILMS

    Energy Technology Data Exchange (ETDEWEB)

    Brigmon, R.; Berry, T.; Narayan, R.

    2010-11-29

    Biotechnology is the application of biological techniques to develop new tools and products for medicine and industry. Due to various properties including chemical stability, biocompatibility, and specific activity, e.g. antimicrobial properties, many new and novel materials are being investigated for use in biosensing, drug delivery, hemodialysis, and other medical applications. Many of these materials are less than 100 nanometers in size. Nanotechnology is the engineering discipline encompassing designing, producing, testing, and using structures and devices less than 100 nanometers. One of the challenges associated with biomaterials is microbial contamination that can lead to infections. In recent work we have examined the functionalization of nanoporous biomaterials and antimicrobial activities of nanocrystalline diamond materials. In vitro testing has revealed little antimicrobial activity against Pseudomonas fluorescens bacteria and associated biofilm formation that enhances recalcitrance to antimicrobial agents including disinfectants and antibiotics. Laser scanning confocal microscopy studies further demonstrated properties and characteristics of the material with regard to biofilm formation.

    2008-01-01

    Loxoscelism (the term used to define accidents by the bite of brown spiders) has been reported worldwide. Clinical manifestations following brown spider bites are frequently associated with skin degeneration, a massive inflammatory response at the injured region, intravascular hemolysis, platelet aggregation causing thrombocytopenia and renal disturbances. The mechanisms by which the venom exerts its noxious effects are currently under investigation. The whole venom is a complex mixture of toxins enriched with low molecular mass proteins in the range of 5-40 kDa. Toxins including alkaline phosphatase, hyaluronidase, metalloproteases (astacin-like proteases), low molecular mass (5.6-7.9 kDa) insecticidal peptides and phospholipases-D (dermonecrotic toxins) have been identified in the venom. The purpose of the present review is to describe biotechnological applications of whole venom or some toxins, with especial emphasis upon molecular biology findings obtained in the last years.

    A consensus meeting to develop practice guidelines and to recommend future clinical trials for radiation therapy (RT), including external beam RT (EBRT), and selective internal RT (SIRT) in hepatocellular carcinoma (HCC) was held at the 5th annual meeting of the Asia-Pacific Primary Liver Cancer Expert consortium. Although there is no randomized phase III trial evidence, the efficacy and safety of RT in HCC has been shown by prospective and retrospective studies using modern RT techniques. Based on these results, the committee came to a consensus on the utility and efficacy of RT in the management of HCC according to each disease stage as follows: in early and intermediate stage HCC, if standard treatment is not compatible, RT, including EBRT and SIRT can be considered. In locally advanced stage HCC, combined EBRT with transarterial chemoembolization or hepatic arterial infusion chemotherapy, and SIRT can be considered. In terminal stage HCC, EBRT can be considered for palliation of symptoms and reduction of morbidity caused by the primary tumor or its metastases. Despite the currently reported benefits of RT in HCC, the committee agreed that there is a compelling need for large prospective studies, including randomized phase III trial evidence evaluating the role of RT. Specifically studies evaluating the efficacy and safety of sequential combination of EBRT and SIRT are strongly recommended. PMID:27493892

    We present results of a high-frequency all-sky search for continuous gravitational waves from isolated compact objects in LIGO's 5th Science Run S5 data, using the computing power of the Einstein@Home volunteer computing project. This is the only dedicated continuous gravitational wave search that probes this high frequency range on S5 data. We find no significant candidate signal, so we set 90%-confidence level upper-limits on continuous gravitational wave strain amplitudes. At the lower end of the search frequency range, around 1250 Hz, the most constraining upper-limit is $5.0\\times 10^{-24}$, while at the higher end, around 1500 Hz, it is $6.2\\times 10^{-24}$. Based on these upper-limits, and assuming a fiducial value of the principal moment of inertia of $10^{38}$kg$\\,$m$^2$, we can exclude objects with ellipticities higher than roughly $2.8\\times10^{-7}$ within 100 pc of Earth with rotation periods between 1.3 and 1.6 milliseconds.

    There are rare times in astronomy when a celestial event, visible in broad daylight, can be used to measure a fundamental parameter and inspire a globe full of school age students. The June 5th/6th transit of Venus was one such event. In celebration, nine astronomy postdocs from the Chilean mainland traveled to Easter Island to lead a series of astronomy outreach activities over three days, culminating in a transit-viewing event. Our team dubbed "Equipo Hetu'u" or "Team Star" in the Rapa Nui (Easter Island native) language spent two days giving astronomy talks and doing hands-on demonstrations at the Museo Antropologico P. Sebastian Englert. In the final day-and-a-half leading up to the transit, we visited the science classes in the majority of the schools on the island, in order to spread the message about the once-in-a-lifetime transit event, highlighting how we planned on using it to measure the distance to the Sun. We estimate over 25% 1500 people) of this remote island participated in one or more of our organized activities. Our experience with this project is an excellent lesson on how to organize, lead, and fully execute a major outreach endeavor that inspires hundreds with minimal resources (save the spectacular event provided by the cosmos).

    International Nuclear Information System (INIS)

    In the European Commission's Nuclear Safety and Radiation Protection key action program, a number of research/development and thematic network projects were approved for funding within the 5th Framework Program (1998-2002). These projects were a posteriori clustered, giving rise to two thematic clusters: SAMEN and MOSES. The main objectives of these clusters are: to ensure the effective and timely exchange of data, information and results between the respective projects, thus avoiding duplication, maximizing synergy and promoting coherence. To provide a forum to review and monitor progress within each project and advise on the direction of research in subsequent periods. To maintain focus on the broader objectives of the program area to which the separate projects are subservient. To ensure each of the projects retains a practical focus (i.e., is undertaken in a manner that will facilitate it finding practical effect. To provide better feedback between the research and potential user communities. To facilitate and promote the timely use of the results/developments in practical decision support systems for off-site emergency management and restoration (in particular in the RODOS system). This paper gives an overview of the various projects and networks belonging to the clusters SAMEN and MOSES, and which represent the state of the art in off site nuclear emergency management and restoration of contaminated environments in Europe (author)

    2015-11-15

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

    Extracellular electron transfer pathways allow certain bacteria to transfer energy between intracellular chemical energy stores and extracellular solids through redox reactions. Microorganisms containing these pathways, exoelectrogens, are a critical part of microbial electrochemical technologies that aim to impact applications in bioenergy, biosensing, and biocomputing. However, there are not yet any examples of economically viable microbial electrochemical technologies due to the limitations of naturally occurring exoelectrogens. Here we first briefly summarize recent discoveries in understanding extracellular electron transfer pathways, then review in-depth the creation of customized and novel exoelectrogens for biotechnological applications. We analyze engineering efforts to increase current production in native exoelectrogens, which reveals that modulating certain processes within extracellular electron transfer are more effective than others. We also review efforts to create new exoelectrogens and highlight common challenges in this work. Lastly, we summarize work utilizing engineered exoelectrogens for biotechnological applications and the key obstacles to their future development. Fueled by the development of genetic tools, these approaches will continue to expand and genetically modified organisms will continue to improve the outlook for microbial electrochemical technologies.

    Full Text Available Plant biotechnology has made significant strides in thc past 15 years encompassing within its fold the spectacular developments in plant molecular biology and genetic engineering. Some of the most vexing problems faced in agricultural ecosystems could be solved with the introduction of transgenic crops endowed with traits for insect pest resistance, herbicide tolerance and resistance to viral diseases. Attention is now being focussed on the development of transgenic plants having industrial, economic, pharmaceutical, nutritional and environmental importance. In the next millennium, crops will serve as factories for the synthesis of valuable metabolites and organic compounds. Agronomically important characters, such as drought tolerance, efficiency in photosynthesis, nutrient use and nitrogen fixation will be manipulated in the next century to enhance the genetic and physiological potential of the crops. Recent developments in the genome sequencing of Arabidopsis, rice and maize will have far reaching implications for future agriculture. Structural and functional genomics of plant species will virtually revolutionise the complexion of agricultural biotechnology as well as human health care. It is imperative that the developing world adopts these fast-changing technologies soon and harness their unprecedented potential for the benefit of the mankind. "

  12. Biotechnology Applications of Tethered Lipid Bilayer Membranes

    Joshua A. Jackman

    2012-12-01

    Full Text Available The importance of cell membranes in biological systems has prompted the development of model membrane platforms that recapitulate fundamental aspects of membrane biology, especially the lipid bilayer environment. Tethered lipid bilayers represent one of the most promising classes of model membranes and are based on the immobilization of a planar lipid bilayer on a solid support that enables characterization by a wide range of surface-sensitive analytical techniques. Moreover, as the result of molecular engineering inspired by biology, tethered bilayers are increasingly able to mimic fundamental properties of natural cell membranes, including fluidity, electrical sealing and hosting transmembrane proteins. At the same time, new methods have been employed to improve the durability of tethered bilayers, with shelf-lives now reaching the order of weeks and months. Taken together, the capabilities of tethered lipid bilayers have opened the door to biotechnology applications in healthcare, environmental monitoring and energy storage. In this review, several examples of such applications are presented. Beyond the particulars of each example, the focus of this review is on the emerging design and characterization strategies that made these applications possible. By drawing connections between these strategies and promising research results, future opportunities for tethered lipid bilayers within the biotechnology field are discussed.

    Full Text Available Probiotics based on normal microflora of the birds using perspective strains become increasingly popular for treatment and prophylaxis of dysbacteriosis in poultry. The purpose of the work is the biotechnological data analysis of the composition and functions of the microflora of different birds’ biotopes. One of biotechnological methods for the study of bacterial flora in the birds is a method of in vivo bacteriological control — analysis of group samples of fresh droppings. To study bird bacterial microflora the method based on vital bacteriological control (group sample study of fresh brood is the most effective. Only 60–70% of microorganisms are identified during the analysis of bowels bird microflora. It is shown that the normal microflora of the birds has a protective function because it is colonized on epithelial intestinal area and competes for power sources, has a wider set of enzymes, and also produces a wide range of exometabolites that determine their antagonistic action on pathogenic and conditionally pathogenic transient microorganisms. To improve modern technologies concerning cultivation of various breeds of birds with high genetic potential it needs full understanding of endogenous microflora role in a bird body. We found that as a source of probiotic strains it is better to use gastrointestinal tract laying hens and/or to make a selection of group tests of their fresh litter. Thus the best probiotic properties are characterized by microorganisms genera Bifidobacterium and Lactobacillus. The results could be used for selection of promising strains to create a acomplex probiotic.

    Ascomycete yeasts are metabolically diverse, with great potential for biotechnology. Here, we report the comparative genome analysis of 29 taxonomically and biotechnologically important yeasts, including 16 newly sequenced. We identify a genetic code change, CUG-Ala, in Pachysolen tannophilus in the clade sister to the known CUG-Ser clade. Our well-resolved yeast phylogeny shows that some traits, such as methylotrophy, are restricted to single clades, whereas others, such as l-rhamnose utilization, have patchy phylogenetic distributions. Gene clusters, with variable organization and distribution, encode many pathways of interest. Genomics can predict some biochemical traits precisely, but the genomic basis of others, such as xylose utilization, remains unresolved. Our data also provide insight into early evolution of ascomycetes. We document the loss of H3K9me2/3 heterochromatin, the origin of ascomycete mating-type switching, and panascomycete synteny at the MAT locus. These data and analyses will facilitate the engineering of efficient biosynthetic and degradative pathways and gateways for genomic manipulation.

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

  18. Governing nanobiotechnology: lessons from agricultural biotechnology regulation

    International Nuclear Information System (INIS)

    This article uses lessons from biotechnology to help inform the design of oversight for nanobiotechnology. Those lessons suggest the following: first, oversight needs to be broadly defined, encompassing not just regulatory findings around safety and efficacy, but also public understanding and acceptance of the technology and its products. Second, the intensity of scrutiny and review should reflect not just risks but also perceptions of risk. Finally, a global marketplace argues for uniform standards or commercially practical solutions to differences in standards. One way of designing oversight to achieve these purposes is to think about it in three phases—precaution, prudence, and promotion. Precaution comes early in the technology or product’s development and reflects real and perceived uncertainties. Prudence governs when risks and hazards have been identified, containment approaches established, and benefits broadly defined. Transparency and public participation rise to the fore. The promotional phase moves toward shaping public understanding and acceptance and involves marketing issues rather than safety ones. This flexible, three-phase approach to oversight would have avoided some of the early regulatory problems with agricultural biotechnology. It also would have led to a more risk-adjusted pathway to regulatory approval. Furthermore, it would avoid some of the arbitrary, disruptive marketing issues that have arisen.

    2015-01-01

    Full Text Available Animal food has to incorporate multiple objectives, ie. it should provide good animal health, good production and reproductive performance, reduce pollution of the environment as well as have the impact on food of animal origin, by supplying it, in addition to basic nutrients, with certain useful substances that can act preventively on the occurrence of various diseases in humans in modern living conditions. This complex task implies the application of scientific knowledge concerning biotechnology in the field of animal feed production, and also includes the use of specific nutrients that are the result of the latest developments in specific disciplines such as molecular biology and genetic engineering. As a result of researches in these areas there were created some varieties of cereals and legumes with improved nutritional properties. On the other hand, obtaining a safe food of animal origin product imposes the use of substances of natural origin (such as probiotics, prebiotics, phytobiotics, enzymes, chelating forms .., which provide better digestibility and more complete utilization of certain nutrients from the feedstuff. In this way, the quantity of undigested substances are significantly reduced as well as soil and the atmosphere pollution. The use of specific additives in animal nutrition resulting from biotechnological research is most frequent when a problem concerning certain level of production or animal health has to be overcome. This implies a group of non-nutritional ingredients which are aimed to regulate the digestive tract microflora, pH, weight gain, as well as to modify metabolic processes etc.

    2011-09-01

    Full Text Available Lipases belong to the group of hydrolases that catalyze the hydrolysis of triacylglycerol lipids to free fatty acids and glycerol. They have significant potential biotechnological applications in catalyzing organic synthesis reactions in non-aqueous solvents using simplified procedures resulting in conversions of high yields. Lipase production has conventionally been performed by submerged fermentation; however, solid-state fermentation processes have been prominent when residues are used as substrates because they serve as low-cost nutrient sources. Microbial lipases can be used as additives in foods to modify and enhance organoleptic properties, as well as in detergents to hydrolyse fats in the treatment of oily effluents, and also have value for pharmaceutical, cosmetic, agrochemical, and oil chemical industries. More recently, they are used in transesterification reactions to convert plant seed oils into biodiesel. The objective of this work was to review the published literature on the production, properties and applications of microbial lipases, and its biotechnological role in producing biodiesel.

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

    This study investigates the medium and long-term opportunities and risks of the biotechnological production of organic chemicals. The objective is to gain better understanding of the techno-economic and the societal viability of White Biotechnology in the coming decades. The key research questions are which products could be made with White Biotechnology, whether these products can contribute to savings of energy use and greenhouse gas (GHG) emissions, under which conditions the products become economically viable, which risks may originate from the use of genetically modified organisms (GMO) in fermentation and what the public perception is. The main purpose of Chapter 2 is to provide an overview of emerging key White Biotechnology products and to explain which chemicals could be produced on their basis. For a selection of these products, detailed environmental and economic assessments are conducted in Chapter 3 (in specific terms, i.e. per tonne of product). Chapter 3 discusses also the so-called Generic Approach which is the methodology we developed and applied to assess future processes and processes, for which very little information is available. In Chapter 4, three scenario projections are developed for Europe (EU-25), thereby assuming benign, moderate and disadvantageous conditions for bio-based chemicals. The purpose of this chapter is hence to understand to which extent restructuring of the chemical sector might occur under which conditions. In Chapter 5, the risks related to the use of White Biotechnology are addressed. The main purpose of this chapter is to give insight into the main risk components influencing the overall risk and of the knowledge gaps. Both conventional risks (e.g., human toxicity and accidents) and risks related to generic modification (e.g., horizontal gene transfer) are analyzed. Since the public perception may play an important role for the implementation of White Biotechnology on a large scale, these issues are discussed in

    Quantitative and qualitative studies of various aspects of the perception of biotechnology were conducted among 469 Slovenian high school students of average age 17 years. Our research aimed to explore relationships among students' pre-knowledge of molecular and human genetics, and their attitudes to four specific biotechnological applications. These applications-Bt corn, genetically modified (GM) salmon, somatic and germ line gene therapy (GT)-were investigated from the viewpoints of usefulness, moral acceptance and risk perception. In addition, patterns and quality of moral reasoning related to the biotechnological applications from the aspect of moral acceptability were examined. Clear gender differences were found regarding the relationship between our students' pre-knowledge of genetics and their attitudes to biotechnological applications. While females with a better genetics background expressed a higher risk perception in the case of GM salmon, their similarly well-educated male colleagues emphasized the risk associated with the use of germ line GT. With all four biotechnological applications, patterns of both rationalistic-deontological and teleological-and intuitive moral reasoning were identified. Students with poorer genetics pre-knowledge applied an intuitive pattern of moral reasoning more frequently than their peers with better pre-knowledge. A pattern of emotive reasoning was detected only in the case of GM salmon. A relatively low quality of students' moral reasoning, as demonstrated by their brief and small number of supporting justifications (explanations), show that there is a strong need for practising skills of argumentation about socio-scientific issues in Slovenian high schools on a much larger scale. The implications for future research and classroom applications are discussed.

    2016-01-01

    Background The Barcelona Clinic Liver Cancer (BCLC) staging and treatment strategy does not recommended surgery for treating BCLC stage B and C hepatocellular carcinoma (HCC). However, numerous Asia-Pacific institutes still perform surgery for this patient group. This consensus report from the 5th Asia-Pacific Primary Liver Cancer Expert Meeting aimed to share opinions and experiences pertaining to liver resection for intermediate and advanced HCCs and to provide evidence to issue recommendations for surgery in this patient group. Summary Thirteen experts from five Asia-Pacific regions were invited to the meeting; 10 of them (Japan: 2, Taiwan: 3, South Korea: 2, Hong Kong: 1, and China: 2) voted for the final consensus. The discussion focused on evaluating the preoperative liver functional reserve and surgery for large tumors, multiple tumors, HCCs with vascular invasion, and HCCs with distant metastasis. The feasibility of future prospective randomized trials comparing surgery with transarterial chemoembolization for intermediate HCC and with sorafenib for advanced HCC was also discussed. The Child-Pugh score (9/10 experts) and indocyanine green retention rate at 15 min (8/10) were the most widely accepted methods for evaluating the preoperative liver functional reserve. All (10/10) experts agreed that portal hypertension, tumor size >5 cm, portal venous invasion, hepatic venous invasion, and extrahepatic metastasis are not absolute contraindications for the surgical resection of HCC. Furthermore, 9 of the 10 experts agreed that tumor resection may be performed for patients with >3 tumors. The limitations of surgery are associated with a poor liver functional reserve, incomplete tumor resection, and a high probability of recurrence. Key Messages Surgery provides significant survival benefits for Asian-Pacific patients with intermediate and advanced HCCs, particularly when the liver functional reserve is favorable. However, prospective randomized controlled trials

    Full Text Available The present systematic literature review is a part of the 5th revision of the Nordic Nutrition Recommendations. The aim was to assess the health effects of different levels of protein intake in infancy and childhood in a Nordic setting. The initial literature search resulted in 435 abstracts, and 219 papers were identified as potentially relevant. Full paper selection resulted in 37 quality-assessed papers (4A, 30B, and 3C. A complementary search found four additional papers (all graded B. The evidence was classified as convincing, probable, limited-suggestive, and limited-inconclusive. Higher protein intake in infancy and early childhood is convincingly associated with increased growth and higher body mass index in childhood. The first 2 years of life is likely most sensitive to high protein intake. Protein intake between 15 E% and 20 E% in early childhood has been associated with an increased risk of being overweight later in life, but the exact level of protein intake above which there is an increased risk for being overweight later in life is yet to be established. Increased intake of animal protein in childhood is probably related to earlier puberty. There was limited-suggestive evidence that intake of animal protein, especially from dairy, has a stronger association with growth than vegetable protein. The evidence was limited-suggestive for a positive association between total protein intake and bone mineral content and/or other bone variables in childhood and adolescence. Regarding other outcomes, there were too few published studies to enable any conclusions. In conclusion, the intake of protein among children in the Nordic countries is high and may contribute to increased risk of later obesity. The upper level of a healthy intake is yet to be firmly established. In the meantime, we suggest a mean intake of 15 E% as an upper limit of recommended intake at 12 months, as a higher intake may contribute to increased risk for later obesity.

    2013-10-09

    Basic research has provided a much better understanding of the genetic networks and regulatory hierarchies in plants. To meet the challenges of agriculture, we must be able to rapidly translate this knowledge into generating improved plants. Therefore, in this Review, we discuss advanced tools that are currently available for use in plant biotechnology to produce new products in plants and to generate plants with new functions. These tools include synthetic promoters, 'tunable' transcription factors, genome-editing tools and site-specific recombinases. We also review some tools with the potential to enable crop improvement, such as methods for the assembly and synthesis of large DNA molecules, plant transformation with linked multigenes and plant artificial chromosomes. These genetic technologies should be integrated to realize their potential for applications to pressing agricultural and environmental problems.

    Oldroyd, Giles E D; Dixon, Ray

    2014-04-01

    The availability of nitrogen is one of the major limiting factors to crop growth. In the developed world, farmers use unsustainable levels of inorganic fertilisers to promote crop production. In contrast, in the developing world inorganic fertilisers are often not available and small-holder farmers suffer the resultant poor yields. Finding alternatives to inorganic fertilisers is critical for sustainable and secure food production. Bacteria and Archaea have evolved the capability to fix atmospheric nitrogen to ammonia, a form readily usable in biological processes. This capability presents an opportunity to improve the nutrition of crop plants, through the introduction into cereal crops of either the nitrogen fixing bacteria or the nitrogenase enzyme responsible for nitrogen fixation. While both approaches are challenging, recent advances have laid the groundwork to initiate these biotechnological solutions to the nitrogen problem. PMID:24679253

    Cytokinins represent an important group of plant growth regulators that can modulate several biotechnological processes owing to their ability to influence almost all stages of plant development and growth. In addition, the use of purine based cytokinins with aromatic substituent in C6 position of the purine moiety in tissue culture techniques is currently experiencing a surge in interest, made possible by the ongoing systematic synthesis and study of these compounds. This review article outlines progress in the synthesis of aromatic cytokinins, the in vitro and in vivo effects of these substances and insights gleaned from their synthesis. As the purine moiety in these compounds can be substituted at several positions, we examine each of the substitution possibilities in relation to the derivatives prepared so far. The discussion highlights the gradual simplification of their preparation in relation to their application in practice and summarizes the relevant organic chemistry literature and published patents.

    Gluconic acid (GA) is a multifunctional carbonic acid regarded as a bulk chemical in the food, feed, beverage, textile, pharmaceutical, and construction industries. The favored production process is submerged fermentation by Aspergillus niger utilizing glucose as a major carbohydrate source, which accompanied product yield of 98%. However, use of GA and its derivatives is currently restricted because of high prices: about US$ 1.20-8.50/kg. Advancements in biotechnology such as screening of microorganisms, immobilization techniques, and modifications in fermentation process for continuous fermentation, including genetic engineering programmes, could lead to cost-effective production of GA. Among alternative carbohydrate sources, sugarcane molasses, grape must show highest GA yield of 95.8%, and banana must may assist reducing the overall cost of GA production. These methodologies would open new markets and increase applications of GA.

    2012-08-01

    Full Text Available Abstract 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.

    Full Text Available Analysis of information on air-conditioning contaminated with heavy metals sludge municipal wastewater points to the actual ecological and chemical problem and its solution could be implemented within the framework of the biological process involving heterotrophic microorganisms. Information on the spread, toxicity, biochemistry, microbiology, colloidal and chemical properties of sludge sediments of municipal wastewater biological treatment is given in the review. These sediments contain vitamins, amino acids, organic matter, heavy metals (micro- and macroelements. Therefore the most rational approach to sludge wastes utilization is their use as an agricultural fertilizer after partial removal of heavy metals. Hence, the interaction of sludge components with heavy metals, modern methods of their removing from biocolloidal systems and biotechnologies of conversion of sludge wastes into fertilizer based on the enhancing of vital ability of sludge biocenoses are discussed.

    This book serves as a reference text for regulatory, industry and academic statisticians and also a handy manual for entry level Statisticians. Additionally it aims to stimulate academic interest in the field of Nonclinical Statistics and promote this as an important discipline in its own right. This text brings together for the first time in a single volume a comprehensive survey of methods important to the nonclinical science areas within the pharmaceutical and biotechnology industries. Specifically the Discovery and Translational sciences, the Safety/Toxiology sciences, and the Chemistry, Manufacturing and Controls sciences. Drug discovery and development is a long and costly process. Most decisions in the drug development process are made with incomplete information. The data is rife with uncertainties and hence risky by nature. This is therefore the purview of Statistics. As such, this book aims to introduce readers to important statistical thinking and its application in these nonclinical areas. The cha...

    Full Text Available Cyanobacteria can function as solar-driven biofactories thanks to their ability to perform photosynthesis and the ease with which they are genetically modified. In this review, we discuss transcriptional parts and promoters available for engineering cyanobacteria. First, we go through special cyanobacterial characteristics that may impact engineering, including the unusual cyanobacterial RNA polymerase, sigma factors and promoter types, mRNA stability, circadian rhythm, and gene dosage effects. Then, we continue with discussing component characteristics that are desirable for synthetic biology approaches, including decoupling, modularity and orthogonality. We then summarize and discuss the latest promoters for use in cyanobacteria regarding characteristics such as regulation, strength and dynamic range and suggest potential uses. Finally, we provide an outlook and suggest future developments that would advance the field and accelerate the use of cyanobacteria for renewable biotechnology.

    Electroporation is already an established technique in several areas of medicine, but many of its biotechnological applications have only started to emerge; we review here some of the most promising. We outline electroporation as a phenomenon and then proceed to applications, first outlining the best established - the use of reversible electroporation for heritable genetic modification of microorganisms (electrotransformation), and then explore recent advances in applying electroporation for inactivation of microorganisms, extraction of biomolecules, and fast drying of biomass. Although these applications often aim to upscale to the industrial and/or clinical level, we also outline some important chip-scale applications of electroporation. We conclude our review with a discussion of the main challenges and future perspectives.

    Sen, Ramkrishna [Department of Biotechnology, Indian Institute of Technology (IIT), Kharagpur, West Bengal 721302 (India)

    2008-12-15

    Biotechnology has played a significant role in enhancing crude oil recovery from the depleted oil reservoirs to solve stagnant petroleum production, after a three-stage recovery process employing mechanical, physical and chemical methods. Biotechnologically enhanced oil recovery processes, known as microbial enhanced oil recovery (MEOR), involve stimulating indigenous reservoir microbes or injecting specially selected consortia of natural bacteria into the reservoir to produce specific metabolic events that lead to improved oil recovery. This also involves flooding with oil recovery agents produced ex situ by industrial or pilot scale fermentation. This paper essentially reviews the operating mechanisms and the progress made in enhanced oil recovery through the use of microbes and their metabolic products. Improvement in oil recovery by injecting solvents and gases or by energizing the reservoir microflora to produce them in situ for carbonate rock dissolution and reservoir re-pressurization has been enunciated. The role of biosurfactants in oil mobilization through emulsification and that of biopolymers for selective plugging of oil-depleted zones and for biofilm formation have been delineated. The spoil sport played by sulfate-reducing bacteria (SRB) in MEOR has also been briefly reviewed. The importance of mathematical models used in predicting the applicability of an MEOR strategy and the microbial growth and transport has been qualitatively discussed. The results of some laboratory studies and worldwide field trials applying ex situ and in situ MEOR technologies were compiled and interpreted. However, the potential of the MEOR technologies has not been fully realized due to poor yield of the useful microbial metabolic products, growth inhibition by accumulated toxic metabolites and longer time of incubation. A complete evaluation and assessment of MEOR from an engineering standpoint based on economics, applicability and performance is required to further

    Mika, Nicole; Zorn, Holger; Rühl, Martin

    2013-01-01

    Insects are the most diverse group of organisms on earth, colonizing almost every ecological niche of the planet. To survive in various and sometimes extreme habitats, insects have established diverse biological and chemical systems. Core components of these systems are enzymes that enable the insects to feed on diverse nutrient sources. The enzymes are produced by either the insects themselves (homologous) or by symbiotic organisms located in the insects' bodies or in their nests (heterologous). The use of these insect-associated enzymes for applications in the fields of food biotechnology and industrial (white) biotechnology is gaining more and more interest. Prominent examples of insect-derived enzymes include peptidases, amylases, lipases, and β-D-glucosidases. Highly potent peptidases for the degradation of gluten, a storage protein that can cause intestinal disorders, may be received from grain pests. Several insects, such as bark and ambrosia beetles and termites, are able to feed on wood. In the field of white biotechnology, their cellulolytic enzyme systems of mainly endo-1,4-β-D-glucanases and β-D-glucosidases can be employed for saccharification of the most prominent polymer on earth-cellulose.

    Recent advances in DNA sequencing technologies have prompted the widespread application of metagenomics for the investigation of novel bioresources (e.g., industrial enzymes and bioactive molecules) and unknown biohazards (e.g., pathogens and antibiotic resistance genes) in natural and engineered microbial systems across multiple disciplines. This review discusses the rigorous experimental design and sample preparation in the context of applying metagenomics in environmental sciences and biotechnology. Moreover, this review summarizes the principles, methodologies, and state-of-the-art bioinformatics procedures, tools and database resources for metagenomics applications and discusses two popular strategies (analysis of unassembled reads versus assembled contigs/draft genomes) for quantitative or qualitative insights of microbial community structure and functions. Overall, this review aims to facilitate more extensive application of metagenomics in the investigation of uncultured microorganisms, novel enzymes, microbe-environment interactions, and biohazards in biotechnological applications where microbial communities are engineered for bioenergy production, wastewater treatment, and bioremediation.

    Full Text Available The two technologies that will essentially determine the shape of things to come in the present century are biotechnology and information technology. A merger of biotechnology and information technology is happening right now, a significant example of which is the success of the human genome project. Biotechnology can be said to have started with the unravelling of the structure of DNA in 1953. The next decade saw exciting developments in our understanding of the fundamentals of functioning of biological system, including the role of DNA in protein synthesis. The discovery of reverse transcriptase and restriction enzymes in 1970s paved the way for further advances, including recombinant DNA and hybridoma technologies, often called 'genetic engineering'. The discovery of polymerase chain reaction in 1986 laid the foundation for large-scale applications of biotechnology in various fields. The practical applications of mapping of the entire human genome would be enormous in terms of better overall health care (diagnosis, therapy and management of disorders. In the field of flora and fauna, it generally happens that biotechnologically-rich countries have poor biodiversity and vice versa. But countries like India and China that have rich biodiversity have, by the use of biotechnology, the potential to become also biotechnologically rich.

  3. A bibliometric assessment of ASEAN collaboration in plant biotechnology

    2015-04-03

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

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

  6. The Role of Biotechnology in Sustainable Agriculture: Views and Perceptions among Key Actors in the Swedish Food Supply Chain

    2015-06-01

    Full Text Available Researchers have put forward agricultural biotechnology as one possible tool for increasing food production and making agriculture more sustainable. In this paper, it is investigated how key actors in the Swedish food supply chain perceive the concept of agricultural sustainability and the role of biotechnology in creating more sustainable agricultural production systems. Based on policy documents and semi-structured interviews with representatives of five organizations active in producing, processing and retailing food in Sweden, an attempt is made to answer the following three questions: How do key actors in the Swedish food supply chain define and operationalize the concept of agricultural sustainability? Who/what influences these organizations’ sustainability policies and their respective positions on agricultural biotechnology? What are the organizations’ views and perceptions of biotechnology and its possible role in creating agricultural sustainability? Based on collected data, it is concluded that, although there is a shared view of the core constituents of agricultural sustainability among the organizations, there is less explicit consensus on how the concept should be put into practice or what role biotechnology can play in furthering agricultural sustainability.

  7. Chinese public understanding of the use of agricultural biotechnology--A case study from Zhejiang Province of China

    Institute of Scientific and Technical Information of China (English)

    2006-01-01

    This study explores the Chinese public's perceptions of, and attitudes to, agriculture and food applications of biotechnology; and investigates the effect of socio-demographic factors on attitudes. A questionnaire survey and interviews were used in an attempt to combine quantitative analysis with qualitative review. The main finding of this study is that the Chinese population has a superficial, optimistic attitude to agricultural biotechnology; and that, in accordance with public attitudes, a cautious policy,with obligatory labelling, should be adopted. The study reveals that education is the factor among socio-demographic variables with the strongest impact on public attitudes. Higher education leads to a more positive evaluation of GM (genetically modified)foods and applications of biotechnology with respect to usefulness, moral acceptability, and suitability for encouragement. In addition, public attitudinal differences depend significantly on area of residence. Compared with their more urban compatriots,members of the public in less developed areas of China have more optimistic attitudes, perceive more benefits, and are more risk tolerant in relation to GM foods and agricultural biotechnology. Finally we obtained a very high rate of"don't know" answers to our survey questions. This suggests that many people do not have settled attitudes, and correspondingly, that the overall public attitude to agricultural biotechnology and GM foods in China is at present somewhat unstable.

    The 5th International Conference on the Intrinsic Josephson Effect and Plasma Oscillations in High-TC Superconductors (known as `PLASMA' for short) took place in London from July 17th to 19th 2006. The meeting was organised jointly by the Superconductivity Group of the Institute of Physics and the European Science Foundation network `Arrays of Quantum Dots and Josephson Junctions' (AQDJJ). It was sponsored by the UK Engineering and Physical Sciences Research Council, AQDJJ, the Japan Society for the Promotion of Physics and the National Institute of Materials Science (NIMS). The meeting was chaired by Paul Warburton of University College London who wishes to put on record his thanks to the conference sponsors for their generosity, without which the conference could not have taken place. Since the previous PLASMA conference in Tsukuba in 2004 the most significant advance in intrinsic Josephson junction (IJJ) research has arguably been the observation of macroscopic quantum tunnelling in IJJs. At the time of the conference this had been observed by both the RIEC/NIMS/AIST collaboration in Japan and by Paul M\\"uller's group in Erlangen. We therefore felt that the conference presented an ideal and timely opportunity for the IJJ community to learn from the more established community of researchers on macroscopic quantum phenomena in low-TC superconductors---and indeed vice versa. As a result a number of leading researchers from the field of low-TC Josephson qubit devices gave several illuminating presentations. Other sessions included those on Josephson vortex dynamics in layered systems and terahertz oscillations in IJJs, in addition to a lively poster session on the first evening. The conference was rounded off by an excellent summary of the highlights of the meeting given by Professor Hu-Jong Lee. The conference organisers would like to thank all those who made the meeting possible and contributed to its smooth running. In addition to the international organising

    In order to investigate the diversity of the intestinal aerobic bacteria of the 5 th instar larvae of Dendrolimus kikuchii Matsumura the characteristic ARDRA fingerprint of the larvae' s intestinal bacteria was obtained by amplifying 16S rDNA with a general primer and digesting the 16S rDNA PCR amplicon (about 1.5 kb) with four restriction enzymes ( Hae Ⅲ , Hind Ⅲ , Hint Ⅰ and Taq Ⅰ ). ARDRA patterns were analyzed by MVSP software using the UPGMA method f and the full complement of 5 representative strains' 16S rDNA were sequenced and blasted in GenBank. Although a few enzyme combinations (Hae Ⅲ + Hind Ⅲ and Hint Ⅰ + Taq Ⅰ ) could not completely digest the 16S rDNA PCR amplicon, the diversity of intestinal bacteria could be inferred from the results obtained from all four restriction enzymes. The results of phylogenetic analysis based on sequencing show that intestinal aerobic bacteria from the 5th instar larvae of D. kikuchii include Klebsietla oxytoca, Yokenella regensburgei, Klebsiella peneumoniae, Citrobacter freundii and Bacillus thuringiensis. This diverse intestinal microbial ecosystem may help protect larvae from invasion by invasive pathogenic bacteria.%采用16s rDNA通用引物进行PCR扩增,16s rDNA扩增片段经寡位点酶组合(HaeⅢ+HindⅢ)和多位点酶组合(Hinf Ⅰ+Taq Ⅰ)酶切后得到ARDRA指纹图谱,ARDRA指纹图谱通过MVSP软件进行聚类分析(UPGMA),并对5大类群的代表菌株进行测序,研究了5龄思茅松毛虫Dendrolimu kikuchii Matsumura肠道细菌的多样性.结果表明:寡位点酶组合(HaeⅢ+HindⅢ)或多位点酶组合(HinfⅠ+Taq Ⅰ)酶切得到的ARDRA指纹图谱不能反映5龄思茅松毛虫肠道细菌的多样性,两组酶切结果组合后可以充分反映5龄思茅松毛虫肠道细菌的多样性.通过测序可知,5龄思茅松毛虫的肠道内主要定植产酸克雷伯氏杆菌(Klebsiella oxytoca)、雷金斯堡约克氏菌(Yokenella regensburgei

    Polyols such as mannitol, erythritol, sorbitol, and xylitol are naturally found in fruits and vegetables and are produced by certain bacteria, fungi, yeasts, and algae. These sugar alcohols are widely used in food and pharmaceutical industries and in medicine because of their interesting physicochemical properties. In the food industry, polyols are employed as natural sweeteners applicable in light and diabetic food products. In the last decade, biotechnological production of polyols by lactic acid bacteria (LAB) has been investigated as an alternative to their current industrial production. While heterofermentative LAB may naturally produce mannitol and erythritol under certain culture conditions, sorbitol and xylitol have been only synthesized through metabolic engineering processes. This review deals with the spontaneous formation of mannitol and erythritol in fermented foods and their biotechnological production by heterofermentative LAB and briefly presented the metabolic engineering processes applied for polyol formation.

    The 5th World Congress on Biomimetics, Artificial Muscles and Nano-Bio and the 4th International Conference on Artificial Muscles were held in Osaka, Japan, 23-27 November 2009. This special section of Smart Materials and Structures is devoted to a selected number of research papers presented at this international conference and congress. Of the 76 or so papers presented at the conference, only 10 papers were finally selected, reviewed and accepted for this special section, following the regular reviewing procedures of the journal. This special section is focused on polymeric artificial muscles, electroactive polymers, multifunctional nanocomposites and their applications. In particular, an electromechanical model for self-sensing ionic polymer-metal composite actuating devices with patterned surface electrodes is presented which discusses the concept of creating self-sensing ionic polymer-metal composite (IPMC) actuating devices with patterned surface electrodes where actuator and sensor elements are separated by a grounded shielding electrode. Eventually, an electromechanical model of the device is also proposed and validated. Following that, there is broad coverage of polytetrahydrofurane-polyethylene oxide-PEDOT conducting interpenetrating polymer networks (IPNs) for high speed actuators. The conducting polymer (poly(3,4-ethylenedioxythiophene)) is incorporated within the IPNs, which are synthesized from polyethylene oxide (PEO)/polytetrahydrofurane (PTHF) networks. PEO/PTHF IPNs are prepared using poly(ethylene glycol) methacrylate and dimethacrylate and hydroxythelechelic PTHF as starting materials. The conducting IPN actuators are prepared by oxidative polymerization of 3,4-ethylenedioxithiophene (EDOT) using FeCl3 as an oxidizing agent within the PEO/PTHF IPN host matrix. Subsequently, giant and reversible magnetorheology of carrageenan/iron oxide magnetic gels are discussed and the effect of magnetic fields on the viscoelastic properties

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

    The search for microorganisms from novel sources and in particular microbial symbioses represents a promising approach in biotechnology. In this context, lichens have increasingly become a subject of research in microbial biotechnology, particularly after the recognition that a diverse community of bacteria other than cyanobacteria is an additional partner to the traditionally recognized algae-fungus mutualism. Here, we review recent studies using culture-dependent as well as culture-independent approaches showing that lichens can harbor diverse bacterial families known for the production of compounds of biotechnological interest and that several microorganisms isolated from lichens, in particular Actinobacteria and Cyanobacteria, can produce a number of bioactive compounds, many of them with biotechnological potential.

  16. Applications of radiations, radioisotopes and nuclear techniques in biotechnology

    International Nuclear Information System (INIS)

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

    Pathogenic bacteria have evolved sophisticated strategies to overcome host defences, to interact with the immune system and to interfere with essential host systems. We coin the term 'patho-biotechnology' to describe the exploitation of these valuable traits in biotechnology, medicine and food. This approach shows promise for the development of novel vaccine and drug delivery systems, as well as for the design of more technologically robust and effective probiotic cultures with improved biotechnological and clinical applications. The genetic tractability of Listeria monocytogenes, the availability of the complete genome sequence of this intracellular pathogen, its ability to cope with stress, and its ability to traverse the gastrointestinal tract and induce a strong cellular immune response make L. monocytogenes an ideal model organism for demonstrating the patho-biotechnology concept.

    2005-03-01

    Plant protoplasts ("naked" cells) provide a unique single cell system to underpin several aspects of modern biotechnology. Major advances in genomics, proteomics, and metabolomics have stimulated renewed interest in these osmotically fragile wall-less cells. Reliable procedures are available to isolate and culture protoplasts from a range of plants, including both monocotyledonous and dicotyledonous crops. Several parameters, particularly the source tissue, culture medium, and environmental factors, influence the ability of protoplasts and protoplast-derived cells to express their totipotency and to develop into fertile plants. Importantly, novel approaches to maximise the efficiency of protoplast-to-plant systems include techniques already well established for animal and microbial cells, such as electrostimulation and exposure of protoplasts to surfactants and respiratory gas carriers, especially perfluorochemicals and hemoglobin. However, despite at least four decades of concerted effort and technology transfer between laboratories worldwide, many species still remain recalcitrant in culture. Nevertheless, isolated protoplasts are unique to a range of experimental procedures. In the context of plant genetic manipulation, somatic hybridisation by protoplast fusion enables nuclear and cytoplasmic genomes to be combined, fully or partially, at the interspecific and intergeneric levels to circumvent naturally occurring sexual incompatibility barriers. Uptake of isolated DNA into protoplasts provides the basis for transient and stable nuclear transformation, and also organelle transformation to generate transplastomic plants. Isolated protoplasts are also exploited in numerous miscellaneous studies involving membrane function, cell structure, synthesis of pharmaceutical products, and toxicological assessments. This review focuses upon the most recent developments in protoplast-based technologies.

    Microorganisms are able to respond effectively to diverse signals from their environment and internal metabolism owing to their inherent sophisticated information processing capacity. A central aim of synthetic biology is to control and reprogramme the signal processing pathways within living cells so as to realise repurposed, beneficial applications ranging from disease diagnosis and environmental sensing to chemical bioproduction. To date most examples of synthetic biological signal processing have been built based on digital information flow, though analogue computing is being developed to cope with more complex operations and larger sets of variables. Great progress has been made in expanding the categories of characterised biological components that can be used for cellular signal manipulation, thereby allowing synthetic biologists to more rationally programme increasingly complex behaviours into living cells. Here we present a current overview of the components and strategies that exist for designer cell signal processing and decision making, discuss how these have been implemented in prototype systems for therapeutic, environmental, and industrial biotechnological applications, and examine emerging challenges in this promising field.

    Currently, prebiotics are all carbohydrates of relatively short chain length. One important group is the fructooligosaccharides (FOS), a special kind of prebiotic associated to the selective stimulation of the activity of certain groups of colonic bacteria. They have a positive and beneficial effect on intestinal microbiota, reducing the incidence of gastrointestinal infections and also possessing a recognized bifidogenic effect. Traditionally, these prebiotic compounds have been obtained through extraction processes from some plants, as well as through enzymatic hydrolysis of sucrose. However, different fermentative methods have also been proposed for the production of FOS, such as solid-state fermentations utilizing various agro-industrial by-products. By optimizing the culture parameters, FOS yields and productivity can be improved. The use of immobilized enzymes and cells has also been proposed as being an effective and economic method for large-scale production of FOS. This article is an overview of the results considering recent studies on FOS biosynthesis, physicochemical properties, sources, biotechnological production and applications.

  13. Biotechnology and the fight against onchocerciasis

    International Nuclear Information System (INIS)

    Biotechnology has recently broken into the rather closed field of human and animal disease vectors and vector control. With regard to blackflies which carry onchocerciasis, in particular, some possible directions which initial research is taking, and which future research might follow are: identification of vectors among the species making up the Simulium damnosum group; identification in the vectors of Onchocerca volvulus strains, of greater or lesser pathogenic nature according to the geographical area; identification of the source of the blood meal; and identification of resistance on an individual level. This research will all contribute towards the development of tools for use in the field, which will enable the epidemiology of onchocerciasis to be better understood, and the fight against this form of parasitosis to be better planned. After a long period using chemical insecticides, the discovery of the larvicidal properties of Bacillus thuringiensis serovar 14 (B.t. H-14), and of Bacillus sphaericus, opens up new horizons. However, the formulation of these biological insecticides is not entirely satisfactory, and research is therefore in progress to discover the toxins inside the commensal organisms of certain disease vectors.

  14. Isolation and Purification of Biotechnological Products

    Hubbuch, Jürgen; Kula, Maria-Regina

    2007-05-01

    The production of modern pharma proteins is one of the most rapid growing fields in biotechnology. The overall development and production is a complex task ranging from strain development and cultivation to the purification and formulation of the drug. Downstream processing, however, still accounts for the major part of production costs. This is mainly due to the high demands on purity and thus safety of the final product and results in processes with a sequence of typically more than 10 unit operations. Consequently, even if each process step would operate at near optimal yield, a very significant amount of product would be lost. The majority of unit operations applied in downstream processing have a long history in the field of chemical and process engineering; nevertheless, mathematical descriptions of the respective processes and the economical large-scale production of modern pharmaceutical products are hampered by the complexity of the biological feedstock, especially the high molecular weight and limited stability of proteins. In order to develop new operational steps as well as a successful overall process, it is thus a necessary prerequisite to develop a deeper understanding of the thermodynamics and physics behind the applied processes as well as the implications for the product.

    Sharma, Krishna Kant

    2016-08-01

    The genome sequences provide a first glimpse into the genomic basis of the biological diversity of filamentous fungi and yeast. The genome sequence of the budding yeast, Saccharomyces cerevisiae, with a small genome size, unicellular growth, and rich history of genetic and molecular analyses was a milestone of early genomics in the 1990s.

    The genome sequences provide a first glimpse into the genomic basis of the biological diversity of filamentous fungi and yeast. The genome sequence of the budding yeast, Saccharomyces cerevisiae, with a small genome size, unicellular growth, and rich history of genetic and molecular analyses was a milestone of early genomics in the 1990s. The subsequent completion of fission yeast, Schizosaccharomyces pombe and genetic model, Neurospora crassa initiated a revolution in the genomics of the fungal kingdom. In due course of time, a substantial number of fungal genomes have been sequenced and publicly released, representing the widest sampling of genomes from any eukaryotic kingdom. An ambitious genome-sequencing program provides a wealth of data on metabolic diversity within the fungal kingdom, thereby enhancing research into medical science, agriculture science, ecology, bioremediation, bioenergy, and the biotechnology industry.

    Currently, prebiotics are all carbohydrates of relatively short chain length. One important group is the fructooligosaccharides (FOS), a special kind of prebiotic associated to the selective stimulation of the activity of certain groups of colonic bacteria. They have a positive and beneficial effect on intestinal microbiota, reducing the incidence of gastrointestinal infections and also possessing a recognized bifidogenic effect. Traditionally, these prebiotic compounds have been obtained through extraction processes from some plants, as well as through enzymatic hydrolysis of sucrose. However, different fermentative methods have also been proposed for the production of FOS, such as solid-state fermentations utilizing various agro-industrial by-products. By optimizing the culture parameters, FOS yields and productivity can be improved. The use of immobilized enzymes and cells has also been proposed as being an effective and economic method for large-scale production of FOS. This article is an overview of the results considering recent studies on FOS biosynthesis, physicochemical properties, sources, biotechnological production and applications. PMID:25519697

    The Office of Program Analysis of the US Department of Energy commissioned this study to evaluate and prioritize research needs in fossil energy biotechnology. The objectives were to identify research initiatives in biotechnology that offer timely and strategic options for the more efficient and effective uses of the Nation`s fossil resource base, particularly the early identification of new and novel applications of biotechnology for the use or conversion of domestic fossil fuels. Fossil energy biotechnology consists of a number of diverse and distinct technologies, all related by the common denominator -- biocatalysis. The expert panel organized 14 technical subjects into three interrelated biotechnology programs: (1) upgrading the fuel value of fossil fuels; (2) bioconversion of fossil feedstocks and refined products to added value chemicals; and, (3) the development of environmental management strategies to minimize and mitigate the release of toxic and hazardous petrochemical wastes. The integration of these programs as viable bioprocessing initiatives proposes an innovative and conceptual principle for the development of a ``new`` approach to fossil energy biotechnology. This unifying principle is NON-AQUEOUS BIOCATALYSIS. Biocatalysis coupled to conventional chemical catalysis in organic-based media offers bioprocessing options uniquely characterized by the selectivity of biocatalysts plus fast reaction rates and specificity of chemical catalysts.

    Marine Actinobacteria, particularly coral-associated Actinobacteria, have attracted attention recently. In this study, the abundance and diversity of Actinobacteria associated with three types of coral thriving in a thermally stressed coral reef system north of the Arabian Gulf were investigated. Coscinaraea columna, Platygyra daedalea and Porites harrisoni have been found to harbor equivalent numbers of culturable Actinobacteria in their tissues but not in their mucus. However, different culturable actinobacterial communities have been found to be associated with different coral hosts. Differences in the abundance and diversity of Actinobacteria were detected between the mucus and tissue of the same coral host. In addition, temporal and spatial variations in the abundance and diversity of the cultivable actinobacterial communities were detected. In total, 19 different actinobacterial genera, namely Micrococcus, Brachybacterium, Brevibacterium, Streptomyces, Micromonospora, Renibacterium, Nocardia, Microbacterium, Dietzia, Cellulomonas, Ornithinimicrobium, Rhodococcus, Agrococcus, Kineococcus, Dermacoccus, Devriesea, Kocuria, Marmoricola, and Arthrobacter, were isolated from the coral tissue and mucus samples. Furthermore, 82 isolates related to Micromonospora, Brachybacterium, Nocardia, Micrococcus, Arthrobacter, Rhodococcus, and Streptomyces showed antimicrobial activities against representative Gram-positive and/or Gram-negative bacteria. Even though Brevibacterium and Kocuria were the most dominant actinobacterial isolates, they failed to show any antimicrobial activity, whereas less dominant genera, such as Streptomyces, did show antimicrobial activity. Focusing on the diversity of coral-associated Actinobacteria may help to understand how corals thrive under harsh environmental conditions and may lead to the discovery of novel antimicrobial metabolites with potential biotechnological applications.
