  1. Biology Reflective Assessment Curriculum

    NASA Astrophysics Data System (ADS)

    Bayley, Cheryl Ann

    Often students and educators view assessments as an obligation and finality for a unit. In the current climate of high-stakes testing and accountability, the balance of time, resources and emphasis on students' scores related to assessment have been slanted considerably toward the summative side. This tension between assessment for accountability and assessment to inform teaching strains instruction and educators' ability to use that information to design learning opportunities that help students develop deeper conceptual understanding. A substantive body of research indicates that formative and reflective assessment can significantly improve student learning. Biology Reflective Assessment Curriculum (BRAC) examines support provided for high school science students through assessment practices. This investigation incorporates the usage of reflective assessments as a guiding practice for differentiated instruction and student choice. Reflective assessment is a metacognitive strategy that promotes self-monitoring and evaluation. The goals of the curriculum are to promote self-efficacy and conceptual understanding in students learning biology through developing their metacognitive awareness. BRAC was implemented in a high school biology classroom. Data from assessments, metacognitive surveys, self-efficacy surveys, reflective journals, student work, a culminating task and field notes were used to evaluate the effectiveness of the curriculum. The results suggest that students who develop their metacognitive skills developed a deeper conceptual understanding and improved feelings of self-efficacy when they were engaged in a reflective assessment unit embedded with student choice. BRAC is a tool for teachers to use assessments to assist students in becoming metacognitive and to guide student choice in learning opportunities.

  2. Two-phase increase in the maximum size of life over 3.5 billion years reflects biological innovation and environmental opportunity

    The maximum size of organisms has increased enormously since the initial appearance of life >3.5 billion years ago (Gya), but the pattern and timing of this size increase is poorly known. Consequently, controls underlying the size spectrum of the global biota have been difficult to evaluate. Our period-level compilation of the largest known fossil organisms demonstrates that maximum size increased by 16 orders of magnitude since life first appeared in the fossil record. The great majority of the increase is accounted for by 2 discrete steps of approximately equal magnitude: the first in the middle of the Paleoproterozoic Era (≈1.9 Gya) and the second during the late Neoproterozoic and early Paleozoic eras (0.6–0.45 Gya). Each size step required a major innovation in organismal complexity—first the eukaryotic cell and later eukaryotic multicellularity. These size steps coincide with, or slightly postdate, increases in the concentration of atmospheric oxygen, suggesting latent evolutionary potential was realized soon after environmental limitations were removed.

    This text is the written version of a talk at the Société de Biologie on February 17, 2016. It contains reflections of a non-biologist scientist on general problems of biological evolution, including the kind of causality involved, the ideas emerging from it, in particular the constructive and structuring character of phenomena such as predation, the role of stability and attractors. This leads to a larger reflection on dialectics, the general framework of evolving processes, which overpasses formal logic and instantaneousness.

  11. The virtue of innovation: innovation through the lenses of biological evolution

    Kell, Douglas B.; Lurie-Luke, Elena

    2015-01-01

    We rehearse the processes of innovation and discovery in general terms, using as our main metaphor the biological concept of an evolutionary fitness landscape. Incremental and disruptive innovations are seen, respectively, as successful searches carried out locally or more widely. They may also be understood as reflecting evolution by mutation (incremental) versus recombination (disruptive). We also bring a platonic view, focusing on virtue and memory. We use ‘virtue’ as a measure of efforts, including the knowledge required to come up with disruptive and incremental innovations, and ‘memory’ as a measure of their lifespan, i.e. how long they are remembered. Fostering innovation, in the evolutionary metaphor, means providing the wherewithal to promote novelty, good objective functions that one is trying to optimize, and means to improve one's knowledge of, and ability to navigate, the landscape one is searching. Recombination necessarily implies multi- or inter-disciplinarity. These principles are generic to all kinds of creativity, novel ideas formation and the development of new products and technologies.

    Rau, Christiane; Gassmann, Oliver; van den Hende, Ellis

    2015-01-01

    This paper identifies technologically reflective individuals and demonstrates their ability to develop innovations that benefit society. Technological reflectiveness (TR) is the tendency to think about the societal impact of an innovation, and those who display this capability in public are individuals who participate in online idea competitions focused on technical solutions for social problems (such as General Electric's eco‐challenge, the James Dyson Award, and the BOSCH Technology Horizon Award). However, technologically reflective individuals also reflect in private settings (e.g., when reading news updates), thus requiring a scale to identify them. This paper describes the systematic development of an easy‐to‐administer multi‐item scale to measure an individual's level of TR. Applying the TR scale in an empirical study on a health monitoring system confirmed that individuals' degree of TR relates positively to their ability to generate (1) more new product features and uses, (2) features with higher levels of societal impact, and (3) features that are more elaborated. This scale allows firms seeking to implement co‐creation in their new product development (NPD) process and sustainable solutions to identify such individuals. Thus, this paper indicates that companies wishing to introduce new technological products with a positive societal impact may profit from involving technologically reflective individuals in the NPD process.

  15. Diffusion of innovations dynamics, biological growth and catenary function

    NASA Astrophysics Data System (ADS)

    Guseo, Renato

    2016-12-01

    The catenary function has a well-known role in determining the shape of chains and cables supported at their ends under the force of gravity. This enables design using a specific static equilibrium over space. Its reflected version, the catenary arch, allows the construction of bridges and arches exploiting the dual equilibrium property under uniform compression. In this paper, we emphasize a further connection with well-known aggregate biological growth models over time and the related diffusion of innovation key paradigms (e.g., logistic and Bass distributions over time) that determine self-sustaining evolutionary growth dynamics in naturalistic and socio-economic contexts. Moreover, we prove that the 'local entropy function', related to a logistic distribution, is a catenary and vice versa. This special invariance may be explained, at a deeper level, through the Verlinde's conjecture on the origin of gravity as an effect of the entropic force.

    Macnaghten, Phil; Owen, Richard; Jackson, Roland

    2016-11-30

    In this article we provide a short review of the debate on responsible innovation and its intersection with synthetic biology, focusing on initiatives we have witnessed and been involved with in the UK. First, we describe the ways in which responsibility in science has been reconfigured institutionally, from an internal focus on the provision of objective and reliable knowledge, to a more external view that embraces the ways in which it has an impact on society. Secondly, we introduce a framework for responsible innovation as a (partial) response to this shift, highlighting its constituent dimensions and the capacities and competencies that are needed to put it into practice. Thirdly, we chart the development of social science research on synthetic biology, addressing its evolution from an 'ethical, legal and social implications' (ELSI) frame to a responsible innovation frame. Fourthly, we review findings from UK social science research with the synthetic biology community setting out challenges for productive collaboration. And finally, we conclude with suggestions on the need for changes in institutional governance. © 2016 The Author(s). published by Portland Press Limited on behalf of the Biochemical Society.

    A growing revolution is under way in the teaching of introductory science to undergraduates. It is driven by concerns about American competitiveness as well as results from recent educational research, which explains why traditional teaching approaches in large classes fail to reach many students and provides a basis for designing improved methods of instruction. Discipline-based educational research in the life sciences and other areas has identified several innovative promising practices and demonstrated their effectiveness for increasing student learning. Their widespread adoption could have a major impact on the introductory training of biology students.

    2012-11-12

    All processes associated with cellular function are likely to contribute to disease. Particularly in the cancer field, most major therapeutic innovations have originated from the elucidation of basic molecular mechanisms by academic researchers. Recent breakthroughs in molecularly targeted drug discovery have made it clear that it is the depth with which a biological process is understood that empowers its translation. We propose that early, more strategic, support of cutting-edge academic research by industry may be more effective for translational purposes than the current model of a late selection of community-evolved projects.

  5. Jet propulsion in animals: theoretical innovation and biological constraints

    NASA Astrophysics Data System (ADS)

    2010-11-01

    Jet propulsion is arguably the oldest and simplest form of animal locomotion, and simple hydrodynamic theory highlights the many possible ways in which animals might maximize speed and minimize metabolic cost while using jet propulsion to travel from one point to another. However, environmental and physiological reality constrains the potential for hydrodynamic innovation. We explore two heuristic examples: Antarctic scallops, in which ecological release from predation apparently constrains the evolution of improved locomotory capacity, and squids, in which the fundamental limitations of muscular contraction constrain the hydrodynamic efficiency of locomotion for all but a small range of sizes. Even simple forms of locomotion can be complex in a biological context.

  6. Old practices, new windows: reflections on a communications skills innovation.

    PubMed

    Cantillon, Peter

    2017-03-01

    Most of the great innovations in communication skills education, from Balint's concept of the 'doctor as drug' to the Calgary Cambridge conceptualisation of the consultation, were founded in general practice. It can be argued however, that there has been a hiatus in the development of new approaches to analysing the consultation since the mid-1990s. It is most welcome therefore that in this issue of the journal two papers are presented that describe and evaluate a novel approach to consultation analysis entitled 'the windows method'. Building on the more structured approaches that preceded it, the windows method offers some genuine innovations in terms of its emphasis on emotional knowledge and the manner in which it addresses many of the potential deficiencies in feedback practice associated with older methods. The new approach is very much in step with current thinking about emotional development and the establishment of appropriate environments for feedback. The windows method has the potential to breathe fresh life into old and well-established communication skills education practices.

    2016-11-30

    Synthetic biology is an emerging field at the interface between biology and engineering, which has generated many expectations for beneficial biomedical and biotechnological applications. At the same time, however, it has also raised concerns about risks or the aim of producing new forms of living organisms. Researchers from different disciplines as well as policymakers and the general public have expressed the need for a form of technology assessment that not only deals with technical aspects, but also includes societal and ethical issues. A recent and very influential model of technology assessment that tries to implement these aims is known as RRI (Responsible Research and Innovation). In this paper, we introduce this model and its historical precursor strategies. Based on the societal and ethical issues which are presented in the current literature, we discuss challenges and opportunities of applying the RRI model for the assessment of synthetic biology. © 2016 The Author(s). published by Portland Press Limited on behalf of the Biochemical Society.

    Nursing students are largely excluded from travel-abroad studies because of demanding curricula, lack of time, and cost. A poll was conducted and distributed to bachelor of science in nursing (BSN) and master of science in nursing (MSN) students who participated in 8-day observational trips. Questions were framed around the themes of cultural awareness, global health care perspective, translating theory into practice, and personal and professional growth. The results were compared with traditional long-term study-abroad outcomes. Participants reported increased cultural awareness through personal interactions and personal growth through continued reflection. Perceived impact on nursing practice was rated as neutral, but narrative comments implied actual influence on practice.

    To describe a teaching challenge intended to increase faculty use of evidence-based and student-centered instructional strategies in the demanding school of pharmacy context with technology-savvy students. A teaching challenge was created that required faculty members to incorporate a "new-to-you" innovative teaching method in a class, course, or experiential activity. The method was linked to at least 1 of 7 evidence-based principles for effective teaching. Faculty members were exposed to colleagues' teaching strategies via brief voluntary presentations at department meetings. A post-challenge survey provided assessment data about the challenge. Responses to a baseline survey provided additional information about what faculty members were already doing (52% response rate). Eighty-one percent of faculty respondents completed the challenge. A wide array of new strategies (13 categories such as flipped classrooms and social media) was implemented and 75% included the use of technology. Nearly all respondents (96%) thought that participation in the challenge was worth the effort and planned to participate again the following year. All faculty members intended to continue using their new strategy and 56% planned additional modifications with future implementations. The challenge demonstrated how multiple goals of curricular improvement, faculty development, and student-centered instruction could be achieved together. The teaching challenge motivated most of the faculty members to try something new to them. Links between evidence-based principles and day-to-day activities were strengthened. The new-to-you design placed the challenge within reach of faculty members regardless of their background, subject, or experience.

    A reflection-mode photoacoustic (PA) imaging system was designed and built to image deep structures in biological tissues. We chose near-infrared laser pulses of 804-nm wavelength for PA excitation to achieve deep penetration. To minimize unwanted surface signals, we adopted dark-field ring-shaped illumination. This imaging system employing a 5-MHz spherically focused ultrasonic transducer provides penetration up to 38 mm in chicken breast tissue. At the 19-mm depth, the axial resolution is 144 microm and the transverse resolution is 560 microm. Internal organs of small animals were imaged clearly.

    Innovations in biological evolution and in technology have many common features. Some of them involve similar processes, such as trial and error and horizontal information transfer. Others describe analogous outcomes such as multiple independent origins of similar innovations. Yet others display similar temporal patterns such as episodic bursts of change separated by periods of stasis. We review nine such commonalities, and propose that the mathematical concept of a space of innovations, discoveries or designs can help explain them. This concept can also help demolish a persistent conceptual wall between technological and biological innovation.

    In European science and technology policy, various styles have been developed and institutionalised to govern the ethical challenges of science and technology innovations. In this paper, we give an account of the most dominant styles of the past 30 years, particularly in Europe, seeking to show their specific merits and problems. We focus on three styles of governance: a technocratic style, an applied ethics style, and a public participation style. We discuss their merits and deficits, and use this analysis to assess the potential of the recently established governance approach of 'Responsible Research and Innovation' (RRI). Based on this analysis, we reflect on the current shaping of RRI in terms of 'doing governance'.

    2013-09-01

    Being reflective is well established as an important conduit of practice development, a desirable tertiary graduate quality and a core competency of health professional membership. By assisting students to be more effective in their ability to reflect, they are better able to formulate strategies to manage issues experienced within a professional context, which ultimately assists them to be better service providers. However, some students are challenged by the practice of reflection and these challenges are even more notable for international students. This paper presents a teaching initiative that focused specifically on enhancing the capacity of an international cohort of nursing students, to engage in reflective practice. The initiative centered on an evaluation of a reflective practice core subject, which was taught in a Master of Nursing programme delivered in Hong Kong. A learning-centered framework was used to evaluate the subject and identify innovative strategies that would better assist international students to develop reflective practices. The outcomes of curriculum and teaching analysis and proposed changes and innovations in teaching practice to support international students are presented and discussed.

The Superfund Innovative Technology Evaluation (SITE) demonstration occurred between September and December 1994 at the Nascolite Superfund site (Nascolite) in Millville, Cumberland County, New Jersey. During the SITE demonstration, critical and noncritical measurements were evaluated. Critical measurements consisted of sample analyses and process measurements that directly impacted meeting the project`s primary technical objective. Critical measurements included collection of liquid and air samples for MMA and VOC analyses; liquid samples to evaluate COD; and flow rate measurements of the influent and effluent liquid streams. Noncritical, or system condition measurements, provided information on operating ranges, reliability, variability, cost-effectiveness, and full-scale remediation potential of the technology.

  3. Some biological reflections on the concept of life.

    PubMed

    Pennazio, Sergio

    2010-01-01

    Life is the natural phenomenon that has always aroused the largest interest of philosophers, theologians and scientists, on which a new science--biology--was founded two century ago just for throwing light on its mechanisms. As the pre-Hellenic culture was not able to separate distinctly philosophy from science, life was interpreted as a spurious flurry of the activity of Nature, in which religion, magic and science were interlaced in an intricate way. The Hippocratic medicine constituted the first attempt to focus attention on life by collecting some biological knowledge in order to maintain man's health. All the subsequent physiologists (from the Hellenic to the Latin period) benefited from the precepts of the Corpus Hippocraticum as long as the Christian religion imposed its theological rules that favoured the question relative to soul ever more closely interlaced with the physiology of body. The concept of life became therefore subjected to a number of opposite theories with strong prevalence of metaphysical conjectures until the 19th century but, in spite of this imposition, splendid successes were achieved by physiologists and naturalists such as Harvey, Descartes, Haller, Malpighi, Spallanzani, Wolff, and others, who laid the foundation of a biology that has Lamarck as promoter. The importance of Lamarck's biology came from the release from metaphysics with the introduction of physical and structural concepts which permeated the experimental biology to come. Three main events characterised the biology of the 19th century: i) the interplay of the new chemistry with biology, ii) the cell theory, iii) the concept of metabolism. These events led biology to the 20th century, the era of biochemistry and molecular genetics. The discoveries relative to metabolism characterised the first half of this century, while the second half was witness to the internal mechanisms regulating the life of cells, perhaps the most advanced success of the biology of all time.

    Water quality is largely influenced by the abundance and diversity of indigenous microbes present within an aquatic environment. Physical, chemical and biological contaminants from anthropogenic activities can accumulate in aquatic systems causing detrimental ecological consequences. Approaches exploiting microbial processes are now being utilized for the detection, and removal or reduction of contaminants. Contaminants can be identified and quantified in situ using microbial whole-cell biosensors, negating the need for water samples to be tested off-site. Similarly, the innate biodegradative processes can be enhanced through manipulation of the composition and/or function of the indigenous microbial communities present within the contaminated environments. Biological contaminants, such as detrimental/pathogenic bacteria, can be specifically targeted and reduced in number using bacteriophages. This mini-review discusses the potential application of whole-cell microbial biosensors for the detection of contaminants, the exploitation of microbial biodegradative processes for environmental restoration and the manipulation of microbial communities using phages.

    2012-10-01

    The promises of modern biotechnology hinge upon the hope that we can understand microscopic cellular complexity and in doing so create novel function. In this regard, the fields of systems and synthetic biology are important for accelerating both our understanding of biological systems and our ability to quantitatively engineer cells. At the nexus of these two fields is a unique synergy that can help attain these goals. Thus, the next greatest advances in biology and biotechnology are arising at the intersection of the top-down systems approach and the bottom-up synthetic approach. Collectively, these developments enable the precise control of cellular state for systems studies and the discovery of novel parts, control strategies, and interactions for the design of robust synthetic function. This review seeks to highlight this activity as well as provide a perspective for future directions. Combining these efforts can provide novel insights into cellular function and lead to robust, novel synthetic design. Copyright © 2011 Elsevier Ltd. All rights reserved.

  6. ECLIPPx: an innovative model for reflective portfolios in life-long learning.

    PubMed

    Cheung, C Ronny

    2011-03-01

    For healthcare professionals, the educational portfolio is the most widely used component of lifelong learning - a vital aspect of modern medical practice. When used effectively, portfolios provide evidence of continuous learning and promote reflective practice. But traditional portfolio models are in danger of becoming outmoded, in the face of changing expectations of healthcare provider competences today. Portfolios in health care have generally focused on competencies in clinical skills. However, many other domains of professional development, such as professionalism and leadership skills, are increasingly important for doctors and health care professionals, and must be addressed in amassing evidence for training and revalidation. There is a need for modern health care learning portfolios to reflect this sea change. A new model for categorising the health care portfolios of professionals is proposed. The ECLIPPx model is based on personal practice, and divides the evidence of ongoing professional learning into four categories: educational development; clinical practice; leadership, innovation and professionalism; and personal experience. The ECLIPPx model offers a new approach for personal reflection and longitudinal learning, one that gives flexibility to the user whilst simultaneously encompassing the many relatively new areas of competence and expertise that are now required of a modern doctor. © Blackwell Publishing Ltd 2011.

    2007-07-25

    Biologic rhythms give insight into normal physiology and disease. They can be used as biomarkers for neuronal degenerations. We present a diverse data set to show that hair and teeth contain an extended record of biologic rhythms, and that analysis of these tissues could yield signals of neurodegenerations. We examined hair from mummified humans from South America, extinct mammals and modern animals and people, both healthy and diseased, and teeth of hominins. We also monitored heart-rate variability, a measure of a biologic rhythm, in some living subjects and analyzed it using power spectra. The samples were examined to determine variations in stable isotope ratios along the length of the hair and across growth-lines of the enamel in teeth. We found recurring circa-annual periods of slow and fast rhythms in hydrogen isotope ratios in hair and carbon and oxygen isotope ratios in teeth. The power spectra contained slow and fast frequency power, matching, in terms of normalized frequency, the spectra of heart rate variability found in our living subjects. Analysis of the power spectra of hydrogen isotope ratios in hair from a patient with neurodegeneration revealed the same spectral features seen in the patient's heart-rate variability. Our study shows that spectral analysis of stable isotope ratios in readily available tissues such as hair could become a powerful diagnostic tool when effective treatments and neuroprotective drugs for neurodegenerative diseases become available. It also suggests that similar analyses of archaeological specimens could give insight into the physiology of ancient people and animals.

    The 20th century was marked by extraordinary advances in our understanding of microbes and infectious disease, but pandemics remain, food and water borne illnesses are frequent, multi-drug resistant microbes are on the rise, and the needed drugs and vaccines have not been developed. The scientific approaches of the past—including the intense focus on individual genes and proteins typical of molecular biology—have not been sufficient to address these challenges. The first decade of the 21st century has seen remarkable innovations in technology and computational methods. These new tools provide nearly comprehensive views of complex biological systems and can provide a correspondingly deeper understanding of pathogen-host interactions. To take full advantage of these innovations, the National Institute of Allergy and Infectious Diseases recently initiated the Systems Biology Program for Infectious Disease Research. As participants of the Systems Biology Program we think that the time is at hand to redefine the pathogen-host research paradigm.

  14. Follow-on biologics: data exclusivity and the balance between innovation and competition.

    PubMed

    Grabowski, Henry

    2008-06-01

    Legislation to create a regulatory pathway for follow-on biologics is currently being considered by the United States Congress. A critical issue in this respect is the period of data exclusivity for innovator companies before a follow-on competitor can rely in part on data obtained for an original biologic for an abbreviated approval. Given the nature of patents on biologics, the period of data exclusivity is anticipated to have a key role in determining how quickly follow-on competitors emerge, and consequently also on the time available for originator companies to recoup their investment. With this issue in mind, this article discusses factors influencing return on investment on biologic research and development. A break-even analysis for a representative portfolio of biologics provides support for a substantial data exclusivity period.

    2014-09-01

    Knowledge of light penetration characteristics is very important in almost all studies in biomedical optics. In this work, the reflectance sampling depth in biological tissues was investigated using Monte Carlo simulations for various common illumination/collection configurations. The analysis shows that the average sampling depth can be described by two simple empirical analytical expressions over the entire typical ranges of absorption and scattering properties relevant to in vivo biological tissue, regardless of the specific illumination/collection configuration details. These results are promising and helpful for the quick, efficient, and accurate design of reflectance studies for various biological tissue applications.

  16. Using Data Exclusivity Grants to Incentivize Cumulative Innovation of Biologics' Manufacturing Processes.

    PubMed

    Levi, Eric Lawrence

    The pharmaceutical market is divided into two types of compounds: small-molecule chemical compounds and large-molecule biologics. Due to biologics’ molecular sizes and the current scientific state of biologics manufacturing, manufacturing facilities and processes require frequent reassessment to ensure production of safe, pure, and potent therapeutics. Manufacturers utilize patent and drug regulatory law to protect their investments and simultaneously signal where innovation and investment are lacking. The current four- and twelve-year regimented structures of the Biologics Price, Competition, and Innovation Act do not keep pace with scientific development; biologics manufacturing processes drift with time, and if a manufacturer can obtain a higher degree of process control, then it should not feel restricted to wait until their exclusivity period lapses. Currently, the FDA rarely grants market exclusivity privileges for manufacturing process improvements alone; hence, manufacturing processes--or at least large portions thereof--are typically withheld as trade secrets or strategically claimed within companion composition claims. As a result, significant opportunity exists in regulatory framework to incentivize the research and development of biologics manufacturing processes. By creating a one- to four-year data exclusivity extension opportunity, manufacturers will feel more comfortable reinvesting their returns on investment towards manufacturing efficiency, and manufacturers can capitalize on the complex-molecule nature of their biologic.

  17. Phage display: applications, innovations, and issues in phage and host biology.

    PubMed

    Wilson, D R; Finlay, B B

    1998-04-01

    In the 7 years since the first publications describing phage-displayed peptide libraries, phage display has been successfully employed in a variety of research. Innovations in vector design and methods to identify target clones account for much of this success. At the same time, not all ventures have been entirely successful and it appears that phage and host biology play important roles in this. A key issue concerns the role played by a displayed peptide or protein in its successful expression and incorporation into virions. While few studies have examined these issues specifically in context of phage display, the literature as a whole provides insight. Accordingly, we review phage biology, relevant aspects of host biology, and phage display applications with the goals of illustrating (i) relevant aspects of the interplay between phage-host biology and successful phage display and (ii) the limitations and considerable potential of this important technology.

  19. Exclusivity strategies and opportunities in view of the Biologics Price Competition and Innovation Act.

    PubMed

    Gaudry, Kate S

    2011-01-01

    Government-provided exclusivity periods provide pharmaceutical companies with incentives to invest in new drugs. Meanwhile, encouraging competition serves another worthy goal of improving the affordability of medications. Decades ago, the Hatch-Waxman Act set forth provisions attempting to balance these objectives in the context of small-molecule drugs. Recently, the Biologics Price Competition and Innovation Act was enacted to meet similar aims in the context of biologic drugs. This article presents a detailed comparison of these two Acts. While the Acts share many global similarities (e.g., providing exclusivity terms and abbreviated approval processes), many differences are also apparent when analyzing details of the provisions. One area of great departure between the Acts is the requirements of how a generic or follow-on applicant must address patents covering a reference product. After describing these differences, the article presents predictions of how reference product sponsors will adapt their patent-prosecution strategies in view of the new Biologics Act.

  20. Nonscanning three-dimensional optical microscope based on the reflectivity-height transformation for biological measurements.

    PubMed

    2013-04-01

    We propose a nonscanning three-dimensional (3D) optical microscope based on reflectivity-height transformation in applications of biological and transparent plate measurements. The reflectivity of a prism can be transformed to the surface height of the specimen based on geometrical optics and the principle of internal reflection. Thus, the pattern of reflectivity is representative of the surface profile. Using charge-coupled device cameras to obtain the two-dimensional image patterns and combining with its reflectivity pattern, the 3D profile can be generated. The lateral resolution is determined by the diffraction limit, and the vertical resolution is better than several nanometers according to the incident angle and polarization used.

  1. The rewards and challenges of teaching innovation in university physics: 4 years' reflection

    NASA Astrophysics Data System (ADS)

    Chang, Wheijen

    2005-04-01

    This paper reports on the transition of the researcher's teaching from before and during an innovation in teaching practice, including 1 year of traditional teaching (1996) and 3 years of teaching based on a constructivist view of learning (1999-2001), in a university physics course in Taiwan. Learning outcomes for each year were evaluated by both standardized conceptual tests and student questionnaire surveys. The results indicated a dilemma the researcher had encountered at an early stage in the teaching innovation, in contrast to the more rewarding outcomes in the longer term. This study indicated the promising yet sophisticated nature of this innovative constructivist teaching. The success of the teaching innovation may not be obtained easily, as criticisms and drawbacks are likely to arise before acceptance is achieved. Conscientious and persistent modifications, based on feedback from the classroom implementation and on understanding of learning theories, are required to achieve success from the teaching innovation.

    This article is concerned with the representation of Synthetic Biology in the media and by biotechnology experts. An analysis was made of German-language media articles published between 2004 and 2008, and interviews with biotechnology-experts at the Synthetic Biology conference SB 3.0 in Zurich 2007. The results have been reflected in terms of the definition of Synthetic Biology, applications of Synthetic Biology and the perspectives of opportunities and risks. In the media, Synthetic Biology is represented as a new scientific field of biology with an engineering-like thinking, while the scientists interviewed mostly define Synthetic Biology as contrary to nature and the natural system. Media articles present Synthetic Biology broadly with positive potential and inform the publics less about the potential risks than about the benefits of Synthetic Biology. In contrast, the experts interviewed reflect more on the risks than the opportunities of Synthetic Biology. Both used metaphors to describe Synthetic Biology and its aspects.

    2010-01-01

    In March 2010, Congress passed the Biologics Price Competition and Innovation Act of 2009 (BPCIA). This law established a statutory pathway for approval of "biosimilars," follow-on versions of innovative biological products. This article traces the history of the BPCIA, beginning with a discussion of the origins of federal regulation of drugs and biologics, including passage of the Hatch-Waxman amendments, in Section I. Section I also describes the development of the European approval framework for biosimilars in the mid-2000s and how this increased interest in creation of a pathway in the United States. The article then provides, in Section II, an overview of early stakeholder discussions in the United States regarding legal and scientific issues relating to biosimilars, spanning the years 1998-2006. The legislative debate began in earnest in late 2006, when the first biosimilars bill was introduced. Section III of the article examines introduced bills, other legislative proposals, and related stakeholder discussion in detail, leading up to enactment of the BPCIA. Section IV describes the BPCIA as enacted, and the paper ends with the authors' concluding observations about the legislative negotiations and their implications for interpretation of the Act.

    Academic screening centers across the world have endeavored to discover small molecules that can modulate biological systems. To increase the reach of functional-genomic and chemical screening programs, universities, research institutes, and governments have followed their industrial counterparts in adopting high-throughput paradigms. As academic screening efforts have steadily grown in scope and complexity, so have the ideas of what is possible with the union of technology and biology. This review addresses the recent conceptual and technological innovation that has been propelling academic screening into its own unique niche. In particular, high-content and whole-organism screening is changing how academics search for novel bioactive compounds. Importantly, we recognize examples of successful chemical probe development that have punctuated the changing technology landscape. PMID:23683346

  6. An innovative spectroelectrochemical reflection cell for rapid protein electrochemistry and ultraviolet/visible/infrared spectroscopy.

    PubMed

    Bernad, Sophie; Mäntele, Werner

    2006-04-15

    A novel electrochemical reflection cell combining electrochemical techniques and spectroscopy which uses a solid gold working electrode as an optical mirror is described. This cell can be used at path lengths as low as a few micrometers and thus is suitable for ultraviolet/visible (UV/Vis) and infrared spectroscopy even for aqueous solutions and suspensions. The cell was designed for small sample volumes of only a few microliters, thus reducing the effort for sample preparation. Due to the short path length of some micrometers, the entire volume is within the Nernst diffusion layer, hence resulting in fast equilibration. Evaluation of the technique is described with direct electrochemistry of horse heart cytochrome c at the gold electrode modified with 4,4'-dithiodipyridine. Cyclic voltammograms indicate rapid and reversible electrochemistry with the correct midpoint potential (52 mV vs Ag/AgCl/3 M KCl). Chronoamperometry and coulometry confirm rapid and complete oxidation and reduction; the cell volume can be entirely fully reduced within less than 10-20 s. Spectroscopy in the UV/Vis region, with potentials at the working electrode stepped between -390 and 390 mV, show perfect titration of the cytochrome c heme bands. A Nernst fit of the alpha band absorption, with redox potential Em and number of electrons n left as parameters, yields a midpoint potential of 49 mV and n=0.9. The potential of this cell in the investigation of biological electron transfer reactions and in the study of bioenergetic systems is discussed.

    This article seeks to reflect on the potential of innovative practices in the design and work of the government bodies that comprise the National System of Offices of the Ombudsman of the Unified Health System. It is divided into two parts, seeking to answer the following question: How to think of and implement innovative practices - which include sustainability - when the people are voicing their urgent demands and these are being heard by the public authorities? These grievances are all the more urgent as they involve the area of Health and can they be promptly discussed, attended and resolved? In the first part, the article discusses the polysemic concept of innovation, focusing on its application in the three spheres of public administration, and highlights the importance of its close correlation with the different notions of information and knowledge in a society such as the one we live in. In the second, it develops a task-force of ideas for the office of the ombudsman and based on this, a draft operational concept of innovation in the role of the office of the ombudsman, considering the context of high speed change and transformations and the complexity inherent to contemporary life and the need for resource management and expertise development in information management.

By analyzing the data and related information at R&D level over the past decades, developmental tendency and R&D patterns were summarized. We found that a growing number of biologics in the pipeline of pharma companies with successful products already in the market though, small molecular entities have primarily dominated drug innovation. Additionally, small/medium size companies will continue to play a key role in the development of small molecule drugs and biologics in a multi-channel integrated process. More importantly, modern and effective R&D strategies in biomedicine development to predict and evaluate efficacy and/or safety of 21st century therapeutics are urgently needed. To face new challenges, developmental strategies were proposed, in terms of molecular targeted medicine, generic drugs, new drug delivery system and protein-based drugs.

    2013-02-01

    We have developed a method of combined interpretation of spectral and spatial characteristics of diffuse reflection of biological tissues, which makes it possible to determine biophysical parameters of the tissue with a high accuracy in real time under conditions of their general variability. Using the Monte Carlo method, we have modeled a statistical ensemble of profiles of diffuse reflection coefficients of skin, which corresponds to a wave variation of its biophysical parameters. On its basis, we have estimated the retrieval accuracy of biophysical parameters using the developed method and investigated the stability of the method to errors of optical measurements. We have showed that it is possible to determine online the concentrations of melanin, hemoglobin, bilirubin, oxygen saturation of blood, and structural parameters of skin from measurements of its diffuse reflection in the spectral range 450-800 nm at three distances between the radiation source and detector.

    The Internal Reflection Sensor, developed by EIC Laboratories, Inc. as a cone penetrometer based technology, provides real-time detection of subsurface non-aqueous phase liquids (NAPLs). The internal reflection element is positioned against the wall of the cone penetrometer probe such that its sensing face is in contact with the soil or groundwater as the cone is pushed into the subsurface. When NAPL is present and in contact with the sensing face, the internally reflected light is diminished. This results in a decrease in the signal output by the detector - a positive indicator of NAPL presence.

    Undergraduate biology education reform aims to engage students in scientific practices such as experimental design, experimentation, and data analysis and communication. Graphs are ubiquitous in the biological sciences, and creating effective graphical representations involves quantitative and disciplinary concepts and skills. Past studies document student difficulties with graphing within the contexts of classroom or national assessments without evaluating student reasoning. Operating under the metarepresentational competence framework, we conducted think-aloud interviews to reveal differences in reasoning and graph quality between undergraduate biology students, graduate students, and professors in a pen-and-paper graphing task. All professors planned and thought about data before graph construction. When reflecting on their graphs, professors and graduate students focused on the function of graphs and experimental design, while most undergraduate students relied on intuition and data provided in the task. Most undergraduate students meticulously plotted all data with scaled axes, while professors and some graduate students transformed the data, aligned the graph with the research question, and reflected on statistics and sample size. Differences in reasoning and approaches taken in graph choice and construction corroborate and extend previous findings and provide rich targets for undergraduate and graduate instruction.

  18. Methods for open innovation on a genome-design platform associating scientific, commercial, and educational communities in synthetic biology.

    Synthetic biology requires both engineering efficiency and compliance with safety guidelines and ethics. Focusing on the rational construction of biological systems based on engineering principles, synthetic biology depends on a genome-design platform to explore the combinations of multiple biological components or BIO bricks for quickly producing innovative devices. This chapter explains the differences among various platform models and details a methodology for promoting open innovation within the scope of the statutory exemption of patent laws. The detailed platform adopts a centralized evaluation model (CEM), computer-aided design (CAD) bricks, and a freemium model. It is also important for the platform to support the legal aspects of copyrights as well as patent and safety guidelines because intellectual work including DNA sequences designed rationally by human intelligence is basically copyrightable. An informational platform with high traceability, transparency, auditability, and security is required for copyright proof, safety compliance, and incentive management for open innovation in synthetic biology. GenoCon, which we have organized and explained here, is a competition-styled, open-innovation method involving worldwide participants from scientific, commercial, and educational communities that aims to improve the designs of genomic sequences that confer a desired function on an organism. Using only a Web browser, a participating contributor proposes a design expressed with CAD bricks that generate a relevant DNA sequence, which is then experimentally and intensively evaluated by the GenoCon organizers. The CAD bricks that comprise programs and databases as a Semantic Web are developed, executed, shared, reused, and well stocked on the secure Semantic Web platform called the Scientists' Networking System or SciNetS/SciNeS, based on which a CEM research center for synthetic biology and open innovation should be established.

    Alzheimer's disease (AD) is a complex neurodegenerative dementing illness. Over the past few years, however, remarkable advances have taken place in understanding both the genetic and molecular biology with the intracellular processing of amyloid and tau and the changes leading to the pathologic formation of extracellular amyloid plaques and the intraneuronal aggregation of hyperphosphorylated tau into neurofibrillary tangles. This progress in our understanding of the molecular pathology has set the stage for clinically meaningful advances in the development of biomarkers. Emerging diagnostic methods that are based on biochemical and imaging biomarkers of disease specific pathology hold the potential to provide effective measures of natural history (marker of disease that is predictive of outcome), biological activity (such as magnitude and frequency of response correlating with drug potency) and markers of surrogate endpoints (single or composite marker that accounts for clinical benefit of the therapy). Markers of biological activity should be also evaluated regarding their value to reflect disease progression, heterogeneity of the clinical population, for early decision making and characterization of new treatments. We focussed on the current status of core analytes which provide reasonable evidence for association with key mechanisms of pathogenesis or neurodegeneration in AD. In addition, feasibility was important, such as availability of a validated assay for the biological measure in question, with properties that included high precision and reliability of measurement, reagents and standards well described. On this basis we reviewed the body of literature that has examined CSF total tau (t-tau) and beta-amyloid 1-42 (Abeta(1-42)), phosphorylated tau (p-tau) and beta-amyloid-antibodies as diagnostic tests for AD versus clinically representative comparison groups. Measurement of t-tau and Abeta(1-42) in the CSF seems useful to discriminate early and incipient

  20. Total-Internal-Reflection Platforms for Chemical and Biological Sensing Applications

    Sapsford, Kim E.

    Sensing platforms based on the principle of total internal reflection (TIR) represent a fairly mature yet still expanding and exciting field of research. Sensor development has mainly been driven by the need for rapid, stand-alone, automated devices for application in the fields of clinical diagnosis and screening, food and water safety, environmental monitoring, and chemical and biological warfare agent detection. The technologies highlighted in this chapter are continually evolving, taking advantage of emerging advances in microfabrication, lab-on-a-chip, excitation, and detection techniques. This chapter describes many of the underlying principles of TIR-based sensing platforms and additionally focusses on planar TIR fluorescence (TIRF)-based chemical and biological sensors.

    We present a comparative evaluation of two simple diffuse reflectance models for biological tissue applications. One model is based on a widely accepted and used in biomedical optics implementation of diffusion theory, and the other one is based on a semiempirical approach derived from basic physical principles. We test the models on tissue phantoms and on human skin, utilizing a standard six-around-one optical fiber probe for light delivery and collection. We show that both models are suitable for use with an optical fiber probe and illustrate the potential, applicability, and validity range of the models.

    2014-01-01

    Special Operations Forces (SOF) medics have written and published numerous practice reflections that intricately describe their practice environments, clinical dilemmas, and suggestions for teaching and practice. The lack of translation of SOF medics experiential evidence to their curriculum has created a gap in evidence-based curriculum development. This study analyzed SOF medics learning and practice patterns and compared it to the evidence in the interdisciplinary clinical literature. After framing the problem, the literature was reviewed to determine appropriate tools by which perceptions and attitudes toward reflection-centered curricula could be measured. A recognizable practice reflection was extracted from the published SOF clinical literature and presented in writing to self-identified SOF medics and medic instructors via a descriptive crossover design, to ensure possible biases were mitigated. To measure SOF medics perceptions of reflection-based curricula, the Dundee Ready Education Environment Measure survey instrument was used, as it has validated psychometric properties and is used worldwide. SOF medics averaged scores of perceptions of their medic education indicated positive but not completely statistically significant preferences toward reflection-based curricula over traditional curriculum.

    1998-07-01

    The main stimulus for the development of the proposed microscope (RIXRALM) is the possibility to view the surface and near surface structure of biological materials, such as cell membranes at much higher resolution than an optical (confocal) microscope. Although the prediction resolution of RIXRALM was lower than a Scanning Electron Microscope (SEM), the possibility to obtain images of cells (membranes) in a more natural, hydrated state and, in many cases, without staining, made the idea of a reflection X-ray microscope very attractive. The specimen can be in an H{sub 2}O saturated He atmosphere at atmospheric pressure. As the image can be obtained quickly (nsec exposure, occurring within seconds of insertion into such an environment), the cell surface can be seen in a state which is very close to its natural condition. Besides, the short exposure time eliminates the effect of motional blurring on the images. Their X-ray reflection microscope fit well in the very large gap in the size of biological objects studied in light microscopy (sub-micron size) and electron microscope (down to a few nanometers size).

    An abbreviated pathway for the approval of biosimilar biological products, often called "follow-on biologics," has been enacted into law as part of the health care legislation recently passed by Congress and signed by the President. The subtitle of the health care bill establishing this approval pathway, the Biologics Price Competition and Innovation Act of 2009, includes many provisions governing the identification of patents relevant to a given biosimilar biological product and the assertion of those patents in infringement suits. This article provides a section-by-section analysis of the patent-related provisions of the new approval pathway for biosimilar biological products, and points out several ways in which the new law differs fundamentally from the Hatch-Waxman Act, which provides the approval pathway for generic versions of small molecule drugs.

    Method and apparatus for examining biological materials using diffuse reflectance spectroscopy and the Kubelka-Munk function. In one aspect, the method is used to determine whether a tissue sample is cancerous or not and comprises the steps of (a) measuring the diffuse reflectance from the tissue sample at a first wavelength and at a second wavelength, wherein the first wavelength is a wavelength selected from the group consisting of 255-265 nm and wherein the second wavelength is a wavelength selected from the group consisting of 275-285 nm; (b) using the Kubelka-Munk function to transform the diffuse reflectance measurement obtained at the first and second wavelengths; and (c) comparing a ratio or a difference of the transformed Kubelka-Munk measurements at the first and second wavelengths to appropriate standards determine whether or not the tissue sample is cancerous. One can use the spectral profile of KMF between 250 nm to 300 nm to determine whether or not the tissue sample is cancerous or precancerous. According to the value at the first and second wavelengths determine whether or not the malignant tissue is invasive or mixed invasive and in situ or carcinoma in situ.

    This research presents a novel design of the collimator, which uses total internal reflection (TIR), convex, and concave lenses for the natural light illumination system (NLIS). The concept of the NLIS is to illuminate building interiors with natural light, which saves energy consumption. The TIR lens is used to collimate the light, and convex and concave lenses are used to converge the light to the required area. The results have shown that the efficiency in terms of achieving collimated light using the proposed collimator at the output of the light collector is better than that of a previous system without a collimator.

  13. A multipurpose scanning near-field optical microscope: Reflectivity and photocurrent on semiconductor and biological samples

    1998-09-01

    A multipurpose scanning near field optical microscope (SNOM) operating at ambient pressure is described with the aim of characterizing the inner parts of biological molecules and any semiconductor or metal microstructure. Therefore, in addition to the requirements of reliability and mechanical stability we have carefully considered analyzing a sample with all available geometries for input/output of photons, in order to get as much information as possible. The SNOM unit consists of two separable cylindrical supports; the lower one contains the sample holder mounted on top of a piezoelectric scanner which is contained in a motor controlled x-y-z stage. A piezo-modulated stretched optical fiber with a few tens of nanometer pinhole and a shear-force apparatus mounted inside the top cylinder allow for topography measurements. The reflectivity of the sample can be measured by applying different methods: the sample can be illuminated on top by an external source, as well as by the optical fiber used for the detection of the reflectivity signal. An aperture in the lower cylinder allows for illumination of the sample on the back: in this case the fiber collects the evanescent wave induced at the top of the sample. Another aperture in the lower cylinder allows measurement of the reflected light which includes a contribution due to the interaction with the fiber. Also photocurrent experiments can be easily performed by illuminating the sample with the fiber and detecting the transmitted signal using a current-voltage converter mounted inside the top cylinder. A video-camera that can reach 170 enlargements is mounted on the top cylinder for positioning the fiber on particular regions of the sample. Reflectivity and photocurrent measurements have been performed on uncoated neurons, CsI compound, Au/GaAs, and PtSi/Si systems, reaching a resolution well below the diffraction limit.

    International fieldwork placements (IFPs) have become very popular among healthcare students including those in occupational therapy programmes. There are many potential benefits that can accrue to the students; however, there are critiques of international placements especially for students going to underserviced areas. The purpose of this paper is to provide a case study/model programme description that critically reflects on six partnerships in three underserviced countries that provide IFPs to students from one Canadian university. The personal opinions of each partner were collected verbally, by email and by a qualitative review of the past 10 years of partnership interaction. Some of the benefits reported by partners include the development of an increased number of sustainable long-term quality placements, orientation materials, student supports and the involvement of university faculty in research and capacity building projects in partner countries. A number of challenges were identified including the need for an expanded formal agreement, more bilateral feedback and examination of supervision models. This paper examines a limited number of partnerships with only one Canadian partner. Direct input of students is not utilized, although feedback given to co-authors by students is reflected. More research is needed on perspectives of partners in IFPs, impact of IFPs on clinical practice in student's home countries, impact of IFPS on underserviced areas and effective strategies for debriefing.

    To help bridge the increasing gap between scientists and the public, we developed an innovative two-semester course called Science Café. In this course, undergraduate biology majors learn to develop communication skills to be better able to explain science concepts and current developments in science to non-scientists. Students develop and host outreach events on various topics relevant to the community, thereby increasing interactions between budding scientists and the public. Such a Science Café course emphasizes development of science communication skills early, at the undergraduate level, and empowers students to use their science knowledge in everyday interactions with the public to increase science literacy, get involved in the local community and engage the public in a dialogue on various pressing science issues. We believe that undergraduate science majors can be great ambassadors for science and are often overlooked since many aspire to go on to medical/veterinary/pharmacy schools. However, science communication skills are especially important for these types of students because when they become healthcare professionals, they will interact with the public as part of their everyday jobs and can thus be great representatives for the field.

    The direct qualitative and quantitative determination of mineral components in shale rocks is a problem that has not been satisfactorily resolved to date. Infrared spectroscopy (IR) is a non-destructive method frequently used in mineral identification, yet challenging due to the similarity of spectral features resulting from quartz, clay, and feldspar minerals. This study reports on a significant improvement of this methodology by combining infrared attenuated total reflection spectroscopy (IR-ATR) with partial least squares (PLS) regression techniques for classifying and quantifying various mineral components present in a number of different shale rocks. The developed multivariate classification model was calibrated using pure component mixtures of the most common shale minerals (i.e., kaolinite, illite, montmorillonite, calcite, and quartz). Using this model, the IR spectra of 11 real-world shale samples were analyzed and evaluated. Finally, the performance of the developed IR-ATR method was compared with results obtained via X-ray diffraction (XRD) analysis.

    Two innovative laser scanning prototypes have been developed at ENEA for diagnostics of large surfaces relevant to monumental cultural heritage. The first, based on amplitude modulation technique in the visible, is a trichromatic (Red /Green /Blue) imaging topologic radar (RGB-ITR) specialized to collect high resolution 3D models. After proper color calibration, it allows for hyper-realistic rendering of colored features on painted surfaces and for precise localization of irregularities. The second is a line scanning system, working either in reflectance or laser induced fluorescence mode, capable of fast 2D monochromatic images acquisition on up to 90 different spectral channels in the visible/UV range, which was developed to investigate the presence of different substances onto the painted surface. Data collected during former field campaigns on frescos by means each scanning system will be reported and discussed extracting information of interest to conservators by means of specific data processing methodologies and respective software tools. Recent results relevant to paints of the Assumption on slate and canvas by Scipione Pulzone named "il Gaetano" collected in two churches in Rome (San Silvestro al Quirinale, Bandini chapel; Santa Caterina dei Funari, Solano della Vetera Chapel) from the late XVI century are presented in order to demonstrate the increased diagnostic capabilities coming from data integration. From combination of reflectance data from both instruments, the first true remote differential colorimetry has been implemented, giving a chance to test the color quality in the future from the archived images.

    A sociodrama addressing college drinking.   This article reports on the development, production, and evaluation of an innovative sociodrama addressing college drinking mental health professionals caring for students who drink at levels that cause negative consequences can use techniques addressed in the sociodrama to help students self-reflect on their alcohol use. The goal is to help students make healthy choices to decrease the negative consequences as a result of drinking. A script for the sociodrama was developed and five students acted out the sociodrama. A facilitator engaged the audience of college students, at scripted pauses, during the production to reflect on the scenes presented. The purpose of the sociodrama is to foster a discussion, to aid in student understanding concerning college drinking, to have students consider and commit to use harm reduction techniques, to access resources, and to correct misperceptions about drinking. The sociodrama format can help address communication challenges, problem solving, and self-awareness. Pre- and post-surveys were administered to test commitment to use harm reduction techniques, assess the perception of a student's own drinking pattern to the perception of their fellow student colleague drinking, assess the student use of resources, and assess the effectiveness of the sociodrama as a means of learning. This research was Institutional Review Board approved. Over 41% of students reported not consuming alcohol the last time they partied or socialized yet reported only 3.8% of their students colleagues did not consume alcohol. Most students (94%) reported that drinking five or more drinks would place them at risk as opposed to estimating that the same amount would put fewer students at risk (75%). Students significantly increased their commitment to use harm reduction techniques. A sociodrama is an effective method of involving students in discussions about college drinking and engaging them in conversation and

    In the modern oceans, the removal of dissolved silica from sea water is principally a biological process carried out by diatoms, with lesser contributions from radiolaria, silicoflagellates, and sponges. Because such silica in sediments is often redistributed locally during diagenesis to from nodular or bedded chert, stratigraphic changes in the facies distribution of early diagenetic chert provide important insights into the development of biological participation in the silica cycle. The abundance of chert in upper Proterozoic peritidal carbonates suggests that at this time silica was removed from seawater principally by abiological processes operating in part of the margins of the oceans. With the evolution of demosponges near the beginning of the Cambrian Period, subtidal biogenetic cherts became increasingly common, and with the Ordovician rise of radiolaria to ecological and biogeochemical prominence, sedimented skeletons became a principal sink for oceanic silica. Cherts of Silurian to Cretaceous age share many features of facies distribution and petrography but they differ from Cenozoic siliceous deposits. These differences are interpreted to reflect the mid-Cretaceous radiation of diatoms and their subsequent rise to domination of the silica cycle. Biogeochemical cycles provide an important framework for the paleobiological interpretation of the organisms that participate in them.

However, traditional darkfield microscopy cannot use a single condenser to support high- and low-numerical-aperture objectives, which limits the modality of WSI. To overcome this limitation, we previously developed a darkfield internal reflection illumination (DIRI) microscope using white light-emitting diodes (LEDs). Although the developed DIRI is useful for biological applications, substantial problems remain to be resolved. In this study, we propose a novel illumination technique called color DIRI. The use of three-color LEDs dramatically improves the capability of the system, such that color DIRI (1) enables optimization of the illumination color; (2) can be combined with an oil objective lens; (3) can produce fluorescence excitation illumination; (4) can adjust the wavelength of light to avoid cell damage or reactions; and (5) can be used as a photostimulator. These results clearly illustrate that the proposed color DIRI can significantly extend WSI modalities for biological applications.

    Small practices often lack the human, financial and technical resources to make necessary practice improvements and infrastructure investments in order to achieve sustainable change that promotes quality and efficiency. To report on an effort to assist small primary care practices in improving quality of care and efficiency of practice management to meet the needs of patients, improve physician satisfaction and enhance the ability of these small practices to survive. We report on an intervention design and the reflections of the implementers on what they learned and what went well or poorly during implementation. Results of the intervention are reported separately (in Quality in Primary Care). Thirty practices underwent the entire intervention. The practices were selected on the basis of practice size, diversity in patient factors, apparent dedication to making practice improvements and geographic location. The main components of the intervention were two site visits to the participating practices by Center for Practice Innovation (CPI); now known as the Centre for Practice Improvement and Innovation, team members. The CPI team provided ongoing advice and support in focus areas selected by practices after initial site visit and assessment. A customised session focusing on the practice report and on helping practices to think about which areas they wished to improve was more effective in engaging practices than didactic presentation. Quality and practice management improvements were observed in information posting, patient education, staff communication and patient safety practices. Having a strong physician champion and a strong office manager determined to make quality improvement changes were important elements for successful change. In addition, practices with greater stability of staff and strong finances were more likely to meet project goals. Small practices today are facing a range of important challenges. The CPI sought to provide successful guidance to

    Fingertip-type pulse oximeters are popular, but their inconvenience for long-term monitoring in daily life means that other types of wearable pulse oximeters, such as reflectance pulse oximeters, need to be developed. For the purpose of developing reflection pulse oximetry, we have analyzed the light propagation in tissue to calculate and estimate the measured intensities of reflected light using the analytical and numerical solutions of the diffusion approximation equation. The reflectance of light from the biological tissue is investigated from theoretical and experimental perspectives, for light in the visible and near-infrared wavelengths. To establish the model, the calculated curves were compared with the analytical solution (AS) of the diffusion approximation equation in biological tissue. The results validated that the diffusion approximation equation could resolve the heterogeneous advanced tissue and the finite element method (FEM) could offer the simulation with higher efficiency and accuracy. Our aim has been to demonstrate the power of the FEM and AS in modeling of the steady-state diffusion approximation in a heterogeneous medium. Also, experimental data and the Monte Carlo model as a gold standard were used to verify the effectiveness of these methods.

    This study proposed a planar solar concentrator featuring alignment-free total-internal-reflection (TIR) collectors and an innovative compound tracker. The compound tracker, combining a mechanical single-axis tracker and scrollable prism sheets, can achieve a performance on a par with dual-axis tracking while reducing the cost of the tracking system and increasing its robustness. The alignment-free TIR collectors are assembled on the waveguide without requiring alignment, so the planar concentrator is relatively easily manufactured and markedly increases the feasibility for use in large concentrators. Further, the identical TIR collector is applicable to various-sized waveguide slab without requiring modification, which facilitates flexibility regarding the size of the waveguide slab. In the simulation model, the thickness of the slab was 2 mm, and its maximal length reached 6 m. With an average angular tolerance of ±0.6°, and after considering both the Fresnel loss and the angular spread of the sun, the simulation indicates that the waveguide concentrator of a 1000-mm length provides the optical efficiencies of 62-77% at the irradiance concentrations of 387-688, and the one of a 2000-mm length provides the optical efficiencies of 52-64.5% at the irradiance concentrations of 645-1148. Alternatively, if a 100-mm horizontally staggered waveguide slab is collocated with the alignment-free TIR collectors, the optical efficiency would be greatly improved up to 91.5% at an irradiance concentration of 1098 (C(geo) = 1200X).

    In some patients with functioning thyroid autonomous nodules preclinical hyperthyroidism is detected. It is important to know, whether in this intermediate clinical state beside the suppression of pituitary TSH secretion other target organs are also affected by serum free-thyroxine and free-triiodothyronine levels still within the normal range. Determining some sensitive, but not specific biologic markers reflecting the impact of thyroid hormones at the peripheral tissue level, it was demonstrated that in the group of preclinical hyperthyroidism the mean level of plasma fibronectin exceeded that of the controls (mean +/- S. D.: 583.5 +/- 163.9 vs. 424.2 +/- 84.1 micrograms/ml, p less than 0.001), serum procollagen-III-peptide concentration was already significantly raised, though its value was still within the normal range (mean +/- S. D.: 0.73 +/- 0.17 vs. 0.57 +/- 0.16 U/ml, p less than 0.05), conversely, mean sex-hormone binding globulin level was the same as in euthyroid controls (mean +/- S. D. 47.4 +/- 18.2 vs. 48.3 +/- 16.3 nmol/l). The value of all three parameters was significantly elevated in patients with toxic nodular goiter. Based on the results of this study "tissue"-thyrotoxicosis is suspected in some patients with preclinical hyperthyroidism, which may have therapeutical implications.

    A number of optical techniques have been reported in the scientific literature as accomplishable methodologies to diagnose diseases in biological tissue, for instance, diffuse reflectance spectroscopy (DRS) and optical polarization imaging (OPI). The skin is the largest organ in the body and consists of three primary layers, namely, the epidermis (the outermost layer exposed to the world), the dermis, and the hypodermis. The epidermis changes from to site to site, mainly because of difference in hydration. A lower water content increase light scattering and reduce the penetration depth of radiation. In this work, two hairless mice have been selected to evaluate their skin features by using DRS and OPI. Four areas of the specimen body were chosen to realize the comparison: back, abdomen, tail, and head. From DRS, it was possible to distinguish the skin nature because of different blood irrigation at dermis. In the other hand, OPI shows pseudo-depolarizing regions in the measured Mueller images related to a spatially varying propagation of the scattered light. This provides information about the cell size in the irradiated skin.

    Congress adopted legislation in 1984 to encourage pharmaceutical companies to develop new drugs, while simultaneously allowing competitors to bring cheaper generic versions to market. More than twenty years later, Congress may be faced with a similar balancing act for biologics. When Congress takes up this issue, it must focus on the substantial differences that exist between biologics and drugs. It should also evaluate the patent law, which is yielding increasingly narrow patents. If additional measures are not adopted in light of the intersection of these factors, then any legislation allowing for "follow-on" biologics could stifle development of new medicines from biotechnology.

    The development of high resolution, high speed imaging techniques allows the study of dynamical processes in biological systems. Lateral resolution improvement of up to a factor of 2 has been achieved using structured illumination. In a total internal reflection fluorescence microscope, an evanescence excitation field is formed as light is total internally reflected at an interface between a high and a low index medium. The <100 nm penetration depth of evanescence field ensures a thin excitation region resulting in low background fluorescence. We present even higher resolution wide-field biological imaging by use of standing wave total internal reflection fluorescence (SW-TIRF). Evanescent standing wave (SW) illumination is used to generate a sinusoidal high spatial frequency fringe pattern on specimen for lateral resolution enhancement. To prevent thermal drift of the SW, novel detection and estimation of the SW phase with real-time feedback control is devised for the stabilization and control of the fringe phase. SW-TIRF is a wide-field superresolution technique with resolution better than a fifth of emission wavelength or ∼100 nm lateral resolution. We demonstrate the performance of the SW-TIRF microscopy using one- and two-directional SW illumination with a biological sample of cellular actin cytoskeleton of mouse fibroblast cells as well as single semiconductor nanocrystal molecules. The results confirm the superior resolution of SW-TIRF in addition to the merit of a high signal/background ratio from TIRF microscopy. PMID:17483188

    A simple device is described, which allows the range of depth of scanning to be reduced when observing thick reflecting biological samples with a confocal scanning laser microscope (CSLM). Thick histological sections of human skin and rat brain stem were mounted between two coverslips ('sandwich' style) and the optical tomography was performed from both sides by turning the 'sandwich' upside-down. The samples were impregnated using standard Golgi-Cox, 'rapid Golgi' or other silver methods. The ability to turn the 'sandwich' upside-down is particularly useful when the reflective structure inspected is deep inside the section, i.e., near the lower surface of the specimen, or when it is opaque to the laser beam or excessively reflective.

    Light reflection produced by the satellite power system and the possible effects of that light on the human eye, plants, and animals were studied. For the human eye, two cases of reflected light, might cause eye damage if viewed for too long. These cases are: (1) if, while in low Earth orbit, the orbital transfer vehicle is misaligned to reflect the Sun to Earth there exists a maximum safe fixation time for the naked eye of 42.4 secs; (2) reflection from the aluminum paint on the back of the orbital transfer vehicle, while in or near low Earth orbit, can be safely viewed by the naked eye for 129 sec. For plants and animals the intensity and timing of light are not a major problem. Ways for reducing and/or eliminating the irradiances are proposed.

    Providing feedback to students as they learn to integrate individual concepts into complex systems is an important way to help them to develop robust understanding, but it is challenging in large, undergraduate classes for instructors to provide feedback that is frequent and directed enough to help individual students. Various scaffolds can be used to help students engage in self-regulated learning and generate internal feedback to improve their learning. This study examined the use of enhanced answer keys with added reflection questions and instruction as scaffolds for engaging undergraduate students in self-regulated learning within an introductory biology course. Study findings show that both the enhanced answer keys and reflection questions helped students to engage in metacognition and develop greater understanding of biological concepts. Further, students who received additional instruction on the use of the scaffolds changed how they used them and, by the end of the semester, were using the scaffolds in significantly different ways and showed significantly higher learning gains than students who did not receive the instruction. These findings provide evidence for the benefit of designing scaffolds within biology courses that will support students in engaging in metacognition and enhancing their understanding of biological concepts.

    The physical and biological assessments of the innovative bilayered wound dressing made of silk and gelatin that we have developed previously were performed to evaluate its efficacy for clinical applications. The absorption ability and dehydration rate of the dressing were assessed using the split-thickness skin graft and leg ulcer wound bed models. The bioactivities of the bilayered wound dressing were evaluated. The bilayered dressing showed continuous absorption rate of wound exudate, providing the suitability for the wound with extended inflammation phase. The dehydration rate of the bilayered dressing was comparable to the commercially available dressing of which the moisture maintenance capability is claimed. The bilayered dressing showed good conformability, as can be seen by the homogeneous distribution pattern of bromophenol blue absorbed. In terms of biological activities, the bilayered dressing was less toxic to skin cells than the commercially available dressing. The bilayered dressing was also shown to promote cell migration and collagen production due to the bioactive protein components. We here concluded that the superior properties of the bilayered dressing over the commercially available dressing were the conformability and biological activities to accelerate the wound healing, while the other properties were comparable to those of commercially available dressing. The data obtained in this study would be very useful for the further evaluation of the bilayered dressing in clinical trial.

  18. Spatially resolved absolute diffuse reflectance measurements for noninvasive determination of the optical scattering and absorption coefficients of biological tissue

    The absorption and transport scattering coefficients of biological tissues determine the radial dependence of the diffuse reflectance that is due to a point source. A system is described for making remote measurements of spatially resolved absolute diffuse reflectance and hence noninvasive, noncontact estimates of the tissue optical properties. The system incorporated a laser source and a CCD camera. Deflection of the incident beam into the camera allowed characterization of the source for absolute reflectance measurements. It is shown that an often used solution of the diffusion equation cannot be applied for these measurements. Instead, a neural network, trained on the results of Monte Carlo simulations, was used to estimate the absorption and scattering coefficients from the reflectance data. Tests on tissue-simulating phantoms with transport scattering coefficients between 0.5 and 2.0 mm-1 and absorption coefficients between 0.002 and 0.1 mm -1 showed the rms errors of this technique to be 2.6% for the transport scattering coefficient and 14% for the absorption coefficients. The optical properties of bovine muscle, adipose, and liver tissue, as well as chicken muscle (breast), were also measured ex vivo at 633 and 751 nm. For muscle tissue it was found that the Monte Carlo simulation did not agree with experimental measurements of reflectance at distances less than 2 mm from the incident beam. Carlo, neural network.

    The aim of this article is to review how yeast has contributed to contemporary biotechnology and to seek underlying principles relevant to its future exploitation for human benefit. Recent advances in systems biology combined with new knowledge of genome diversity promise to make yeast the eukaryotic workhorse of choice for production of everything from probiotics and pharmaceuticals to fuels and chemicals. The ability to engineer new capabilities through introduction of controlled diversity based on a complete understanding of genome complexity and metabolic flux is key. Here, we briefly summarise the history that has led to these apparently simple organisms being employed in such a broad range of commercial applications. Subsequently, we discuss the likely consequences of current yeast research for the future of biotechnological innovation.

    The determination of optical parameters of biological tissues is essential for the application of optical techniques in the diagnosis and treatment of diseases. Diffuse Reflection Spectroscopy is a widely used technique to analyze the optical characteristics of biological tissues. In this paper we show that by using diffuse reflectance spectra and a new mathematical model we can retrieve the optical parameters by applying an adjustment of the data with nonlinear least squares. In our model we represent the spectra using a Fourier series expansion finding mathematical relations between the polynomial coefficients and the optical parameters. In this first paper we use spectra generated by the Monte Carlo Multilayered Technique to simulate the propagation of photons in turbid media. Using these spectra we determine the behavior of Fourier series coefficients when varying the optical parameters of the medium under study. With this procedure we find mathematical relations between Fourier series coefficients and optical parameters. Finally, the results show that our method can retrieve the optical parameters of biological tissues with accuracy that is adequate for medical applications. PMID:23082281

  7. Innovation in biological production and upgrading of methane and hydrogen for use as gaseous transport biofuel.

    2016-01-01

    Biofuels derived from biomass will play a major role in future renewable energy supplies in transport. Gaseous biofuels have superior energy balances, offer greater greenhouse gas emission reductions and produce lower pollutant emissions than liquid biofuels. Biogas derived through fermentation of wet organic substrates will play a major role in future transport systems. Biogas (which is composed of approximately 60% methane/hydrogen and 40% carbon dioxide) requires an upgrading process to reduce the carbon dioxide content to less than 3% before it is used as compressed gas in transport. This paper reviews recent developments in fermentative biogas production and upgrading as a transport fuel. Third generation gaseous biofuels may be generated using marine-based algae via two-stage fermentation, cogenerating hydrogen and methane. Alternative biological upgrading techniques, such as biological methanation and microalgal biogas upgrading, have the potential to simultaneously upgrade biogas, increase gaseous biofuel yield and reduce carbon dioxide emission.

    Roundworms belong to a diverse phylum (Nematoda) which is comprised of many parasitic species including whipworms (genus Trichuris). These worms have adapted to a biological niche within the host and exhibit unique morphological characteristics compared with other nematodes. Although these adaptations are known, the underlying molecular mechanisms remain elusive. The availability of genomes and transcriptomes of some whipworms now enables detailed studies of their molecular biology. Here, we defined and curated the full complement of an important class of enzymes, the protein kinases (kinomes) of two species of Trichuris, using an advanced and integrated bioinformatic pipeline. We investigated the transcription of Trichuris suis kinase genes across developmental stages, sexes and tissues, and reveal that selectively transcribed genes can be linked to central roles in developmental and reproductive processes. We also classified and functionally annotated the curated kinomes by integrating evidence from structural modelling and pathway analyses, and compared them with other curated kinomes of phylogenetically diverse nematode species. Our findings suggest unique adaptations in signalling processes governing worm morphology and biology, and provide an important resource that should facilitate experimental investigations of kinases and the biology of signalling pathways in nematodes.

  11. From protoplasmic theory to cellular systems biology: a 150-year reflection.

    Present-day cellular systems biology is producing data on an unprecedented scale. This field has generated a renewed interest in the holistic, "system" character of cell structure-and-function. Underlying the data deluge, however, there is a clear and present need for a historical foundation. The origin of the "system" view of the cell dates to the birth of the protoplasm concept. The 150-year history of the role of "protoplasm" in cell biology is traced. It is found that the "protoplasmic theory," not the "cell theory," was the key 19th-century construct that drove the study of the structure-and-function of living cells and set the course for the development of modern cell biology. The evolution of the "protoplasm" picture into the 20th century is examined by looking at controversial issues along the way and culminating in the current views on the role of cytological organization in cellular activities. The relevance of the "protoplasmic theory" to 21st-century cellular systems biology is considered.

    2017-01-01

    Glaucoma is a common degenerative disease affecting retinal ganglion cells (RGC) and optic nerve axons, with progressive and chronic course. It is one of the most important reasons of social blindness in industrialized countries. Glaucoma can lead to the development of irreversible visual field loss, if not treated. Diagnosis may be difficult due to lack of symptoms in early stages of disease. In many cases, when patients arrive at clinical evaluation, a severe neuronal damage may have already occurred. In recent years, newer perspective in glaucoma treatment have emerged. The current research is focusing on finding newer drugs and associations or better delivery systems in order to improve the pharmacological treatment and patient compliance. Moreover, the application of various stem cell types with restorative and neuroprotective intent may be found appealing (intravitreal autologous cellular therapy). Advances are made also in terms of parasurgical treatment, characterized by various laser types and techniques. Moreover, recent research has led to the development of central and peripheral retinal rehabilitation (featuring residing cells reactivation and replacement of defective elements), as well as innovations in diagnosis through more specific and refined methods and inexpensive tests.

    Scientific research at universities has a crucial role in leveraging a country's innovative potential. Sectors that require greater investments in technology for the development of their research, such as biotechnology, need to be aware of the frontier state-of-the-art technology and the knowledge incrusted within it. Although the information available in scientific articles is well explored in academic environment, the patent literature, where much of the technological information is present, is still poorly accessed. This chapter is intended to instruct students and researchers at universities to look at patent document analysis as a source of scientific and technological information and explore its applications. Within this chapter, we use the technological area regarding immunoglobulins inventions (monoclonal and polyclonal antibodies) as example to provide directions on how to develop a patent landscape to get an overview of the inventions in a certain field; how to map a collaborative network of inventors/assignees to help the pursuit and identification of future partnerships; and lastly we describe the steps of how to set up a network of patent citations with the aim of forecasting emerging technologies. We strongly believe that incorporate data from patents in planning phase of research projects at academia, as well as to establish partnerships and join R&D efforts to invest on promising technologies, is of great relevance to leverage the growth of the biotechnology sector.

  14. Characterization and biological abatement of diffuse methane emissions and odour in an innovative wastewater treatment plant.

    2015-01-01

    An innovative and patented process for medium-high strength sewage which comprises an anaerobic step followed by a hybrid anoxic-aerobic chamber and a final ultrafiltration stage was characterized in terms of methane fugitive emissions as well as odours. The operation at ambient temperature implies higher methane content in the liquid anaerobic effluent, which finally causes concentrations around 0.01-2.4% in the off-gas released in the anoxic-aerobic chamber (1.25% average). Mass balances indicate that these emissions account for up to 30-35% of the total methane generated in the anaerobic reactor. A conventional biofilter (BF) operated at an empty bed residence time of 4 min was used to treat these emissions for 70 d. In spite of the fluctuations in the methane inlet concentrations derived from the operation of the wastewater treatment plant (WWTP), it was possible to operate at pseudo-steady-state conditions, achieving average removal efficiencies of 76.5% and maximum elimination capacities of 30.1 g m(-3) h(-1). Odour removal was quantified as 99.1%. Fluorescence in situ hybridization probes as well as metabolic activity assays demonstrated the suitability of the biomass developed in the WWTP as inoculum to start up the BF due to the presence of methanotrophic bacteria.

  16. Comparative genomics and structural biology of the molecular innovations of eukaryotes.

    Eukaryotes encode numerous proteins that either have no detectable homologs in prokaryotes or have only distant homologs. These molecular innovations of eukaryotes may be classified into three categories: proteins and domains inherited from prokaryotic precursors without drastic changes in biochemical function, but often recruited for novel roles in eukaryotes; new superfamilies or distinct biochemical functions emerging within pre-existing protein folds; and domains with genuinely new folds, apparently 'invented' at the outset of eukaryotic evolution. Most new folds emerging in eukaryotes are either alpha-helical or stabilized by metal chelation. Comparative genomics analyses point to an early phase of rapid evolution, and dramatic changes between the origin of the eukaryotic cell and the advent of the last common ancestor of extant eukaryotes. Extensive duplication of numerous genes, with subsequent functional diversification, is a distinctive feature of this turbulent era. Evolutionary analysis of ancient eukaryotic proteins is generally compatible with a two-symbiont scenario for eukaryotic origin, involving an alpha-proteobacterium (the ancestor of the mitochondria) and an archaeon, as well as key contributions from their selfish elements.

    The centennial of the Journal of Morphology provides a fitting occasion to reflect upon the condition of American biology surrounding the founding years of the Journal. The Journal was started by C.O. Whitman in 1887. At this same time, the American biological community experienced a gradual change from a community of amateurs based within the natural history tradition to a professional community based within universities with specialized research programs. Many of the changes associated with this maturation process are exhibited in the pages of the first ten volumes of the Journal. They show that the Journal played a central role in communicating research methods and questions to the growing community of professional biologists. Moreover, these same volumes provide an accurate record of the character of the morphological sciences at the end of the 19th century.

    2011-01-01

    The Biologics Price Competition and Innovation Act of 2009 ("Biosimilars Act") is for the field of pharmaceutical products the single most important legislative development since passage of the Drug Price Competition and Patent Term Restoration Act of 1984 ("Hatch-Waxman Act"), on which portions of the Biosimilars Act are clearly patterned. Congress revised section 351 of the Public Health Service Act (PHSA) to create a pathway for FDA approval of "biosimilar" biological products. Each biosimilar applicant is required to cite in its application a "reference product" that was approved on the basis of a full application containing testing data and manufacturing information, which is owned and was submitted by another company and much of which constitutes trade secret information subject to constitutional protection. Because the Biosimilars Act authorizes biosimilar applicants to cite these previously approved applications, the implementation of the new legislative scheme raises critical issues under the Fifth Amendment of the Constitution, pursuant to which private property--trade secrets included--may not be taken for public use, without "just compensation." FDA must confront those issues as it implements the scheme set out in the Biosimilars Act. This article will discuss these issues, after providing a brief overview of the Biosimilars Act and a more detailed examination of the law of trade secrets.

  19. [Biological rhythm as a reflection of the unity of creation and destruction (life and death)].

    2002-01-01

    The paper deals with the analysis of fundamental aspects of nature of the biological rhythm, antinomies incident to this phenomenon, its relation to the phenomena of life and death. The biological rhythm is viewed as an exemplification of the singleness of two qualitatively different states--destruction and creation, dissimilation and assimilation. Since destruction of biological structures in the course of dissimilation is irreversible by character, there is every reason to equal it with death, and to consider life the counter process of assimilative synthesis (creation) of chemical compounds directed toward revival of living substance. From this standpoint, the day phase of the circadian rhythm marked by dominance of destructive processes is a kind of death, whereas the night phase characterized by prevalence of the recovery processes signifies life. That is why the daytime status of organism differs from that at night, which is directly related to diagnostics of internal diseases: in the daytime and at night the same patient seems to be two different persons. Therefore, investigating him not only in the daytime but also at night, we could get more intimate understanding of his diseases, that is make an exhaustive diagnosis. Efficiency of night investigations combined with daytime ones has been confirmed by clinical investigations.

    Many species of microalgae produce hydrocarbons, polysaccharides, and other valuable products in significant amounts. However, large-scale production of algal products is not yet competitive against non-renewable alternatives from fossil fuel. Metabolic engineering approaches will help to improve productivity, but the exact metabolic pathways and the identities of the majority of the genes involved remain unknown. Recent advances in bioinformatics and systems-biology modeling coupled with increasing numbers of algal genome-sequencing projects are providing the means to address this. A multidisciplinary integration of methods will provide synergy for a systems-level understanding of microalgae, and thereby accelerate the improvement of industrially valuable strains. In this review we highlight recent advances and challenges to microalgal research and discuss future potential.

    Lung cancer (LC) is a number one killer of cancer-related death among men and women worldwide. Major advances have been made in the diagnosis, staging and use of surgery for LC, but systemic chemotherapy and radiotherapy alone or in combination with some targeted agents remains the core treatment of advanced LC. Unfortunately, in spite of improved diagnosis, surgical methods and new treatments, mortality is still extremely high among LC patients. To understand the precise functioning of signaling pathways associated with resistance to current treatments in LC, as well as to identify novel treatment regimens, a holistic approach to analyze signaling networks should be applied. Here, we describe systems biology-based approaches to generate biomarkers and novel therapeutic targets in LC, as well as how this may contribute to personalized treatment for this malignancy.

    Measurement of photon penetration in biological tissues is a central theme in optical imaging. A great number of endogenous tissue factors such as absorption, scattering, and anisotropy affect the path of photons in tissue, making it difficult to predict the penetration depth at different wavelengths. Traditional studies evaluating photon penetration at different wavelengths are focused on tissue spectroscopy that does not take into account the heterogeneity within the sample. This is especially critical in shortwave infrared where the individual vibration-based absorption properties of the tissue molecules are affected by nearby tissue components. We have explored the depth penetration in biological tissues from 900 to 1650 nm using Monte-Carlo simulation and a hyperspectral imaging system with Michelson spatial contrast as a metric of light penetration. Chromatic aberration-free hyperspectral images in transmission and reflection geometries were collected with a spectral resolution of 5.27 nm and a total acquisition time of 3 min. Relatively short recording time minimized artifacts from sample drying. Results from both transmission and reflection geometries consistently revealed that the highest spatial contrast in the wavelength range for deep tissue lies within 1300 to 1375 nm however, in heavily pigmented tissue such as the liver, the range 1550 to 1600 nm is also prominent.

    A computational skin re ectance model is used here to provide the re ectance, absorption, scattering, and transmittance based on the constitutive biological components that make up the layers of the skin. The changes in re ectance are mapped back to deviations in model parameters, which include melanosome level, collagen level and blood oxygenation. The computational model implemented in this work is based on the Kubelka- Munk multi-layer re ectance model and the Fresnel Equations that describe a generic N-layer model structure. This assumes the skin as a multi-layered material, with each layer consisting of specic absorption, scattering coecients, re ectance spectra and transmittance based on the model parameters. These model parameters include melanosome level, collagen level, blood oxygenation, blood level, dermal depth, and subcutaneous tissue re ectance. We use this model, coupled with support vector machine based regression (SVR), to predict the biological parameters that make up the layers of the skin. In the proposed approach, the physics-based forward mapping is used to generate a large set of training exemplars. The samples in this dataset are then used as training inputs for the SVR algorithm to learn the inverse mapping. This approach was tested on VIS-range hyperspectral data. Performance validation of the proposed approach was performed by measuring the prediction error on the skin constitutive parameters and exhibited very promising results.

  4. Estimation of regional hemoglobin concentration in biological tissues using diffuse reflectance spectroscopy with a novel spectral interpretation algorithm.

    Chen, P; Fernald, B; Lin, W

    2011-07-07

    Both in medical research and clinical settings, regional hemoglobin concentrations ([Hb]) in the microcirculation of biological tissues are highly sought. Diffuse reflectance spectroscopy has been proven to be a favorable method by which to detect regional [Hb]. This paper introduces a new algorithm to retrieve [Hb] information from diffuse reflectance spectra. The proposed algorithm utilizes the natural logarithmic operation and the differential wavelet transform to effectively quench the scattering effects, and then employs the concept of isosbestic wavelength in the transformed spectra to reduce the effects of hemoglobin oxygenation. As a result, the intensity at the defined isosbestic wavelength of the transformed spectra is a good indicator of [Hb] estimation. The algorithm was derived and validated using theoretical spectra produced by Monte Carlo simulation of photon migration. Its accuracy was further evaluated using liquid tissue phantoms, and its clinical utility with an in vivo clinical study of brain tumors. The results demonstrate the applicability of the algorithm for real-time [Hb] estimations from diffuse reflectance spectra, acquired by means of a fiber-optic spectroscopy system.

  5. The Athlete Biological Passport: an integral element of innovative strategies in antidoping.

    2014-05-01

    Concern for the health of athletes and integrity of sport resulted in the banning of specific substances although many years passed before analytical testing took place. Soon doping control programmes became synonymous with urine tests and adverse analytical findings. This system has its limits due to the detection window of prohibited substances, the timing of sample collections and the sophistication of some doping regimens. There have been a number of situations where these limits were demonstrated by athletes who proclaimed innocence based on passing their analytical tests only to later confess to doping. New strategies were called for to protect clean athletes. In the current World Anti-Doping Code, there are eight means to an Anti-Doping Rule Violation (ADRV). Article 2.2 states that the use of a prohibited substance may be established by any reliable means including witness statements, documentary evidence or evaluations of longitudinal profiling. In 2006, the World Anti-Doping Agency (WADA) with the support of some International Federations (IFs) gathered a group of experts to develop a harmonised programme on longitudinal profiling, or serial analysis of indirect biomarkers of doping, that was both scientifically and legally robust. This culminated in the WADA Athlete Biological Passport (ABP) Operating Guidelines and Technical Documents, published in 2009. The ABP is a paradigm that infers the use of prohibited substance (or method) by the monitoring of discriminant biomarkers over time. The haematological module detects blood manipulation by the use of erythropoietic stimulating agents or via blood transfusions. The steroidal module aims to identify endogenous anabolic androgenic steroids when administered exogenously and other indirect steroid doping substances or methods. Other ABP modules (endocrine, 'omics') are being developed. The term passport, first coined in 2000, is now defined in the ABP Guidelines as the longitudinal profile and all other

    Intellectual property rights (IPRs) have become a key concern for researchers and industry in basically all high-tech sectors. IPRs regularly figure prominently in scientific journals and at scientific conferences and lead to dedicated workshops to increase the awareness and "IPR savviness" of scientists. In 2015, Biotechnology Journal published a report from an expert meeting on "Synthetic Biology & Intellectual Property Rights" organized by the Danish Agency for Science, Technology and Innovation sponsored by the European Research Area Network (ERA-Net) in Synthetic Biology (ERASynBio), in which we provided a number of recommendations for a variety of stakeholders [1]. The current article offers some deeper reflections about the interface between IPRs, standards and data exchange in systems biology (SysBio) resulting from an Expert Meeting funded by another ERA-Net, ERASysAPP. The meeting brought together experts and stakeholders (e.g. scientists, company representatives, officials from public funding organizations) in SysBio from different European countries. Despite the different profiles of the stakeholders at the meeting and the variety of interests, many concerns and opinions were shared. In case particular views were expressed by a specific type of stakeholder, this will be explicitly mentioned in the text. In this article, we explore a number of particularly relevant issues that were discussed at the meeting and offer some recommendations. SysBio involves the study of biological systems at a so-called systems level. This is not a new concept in the life sciences - many former approaches in physiology, enzymology and other scientific disciplines have already taken a systemic view of selected biological subjects. Yet, SysBio has gained strong interest within the past 10 to 15 years. One predominant reason and a critical prerequisite for this success story being that the relevant scientific methodologies and research tools have become far more powerful and

    2014-05-01

    Science education reform documents identify nature of science (NOS) as a critical component of scientific literacy and call for universities, colleges, and K-12 schools to explicitly integrate NOS learning into science curricula. In response to these calls, this study investigated the classroom practices of nine graduate assistants (GAs) who taught expository and inquiry laboratories that implemented an explicit and reflective (ER) pedagogy to teach NOS. The purpose of this qualitative study was to better understand the experiences that enabled or inhibited GA implementation of an ER strategy in a college setting. The findings revealed that achieving quality implementation in this setting was very difficult. Factors such as GAs' ability to foster meaningful classroom discussions, laboratory logistics (e.g. lack of time and supplies), and the value undergraduates and GAs saw in learning about NOS were identified by GAs and observed by the researchers as barriers to the technique maximizing its potential. Thus, for meaningful infusion of NOS into science curricula, pedagogical support for GAs to manage meaningful classroom discussions in support of NOS or other complex topics is recommended for an ER approach to NOS learning to be successful in college settings.

Consensus clustering performed on gene expression data from a meta-dataset of high-grade, muscle-invasive bladder tumors identified two intrinsic, molecular subsets of high-grade bladder cancer, termed "luminal" and "basal-like," which have characteristics of different stages of urothelial differentiation, reflect the luminal and basal-like molecular subtypes of breast cancer, and have clinically meaningful differences in outcome. A gene set predictor, bladder cancer analysis of subtypes by gene expression (BASE47) was defined by prediction analysis of microarrays (PAM) and accurately classifies the subtypes. Our data demonstrate that there are at least two molecularly and clinically distinct subtypes of high-grade bladder cancer and validate the BASE47 as a subtype predictor. Future studies exploring the predictive value of the BASE47 subtypes for standard of care bladder cancer therapies, as well as novel subtype-specific therapies, will be of interest.

  9. Reflections on implementing several models of teaching in a high school biology class

    NASA Astrophysics Data System (ADS)

    Baldwin, Michael E.

    This research investigates the challenges faced in enacting instructional models that previous research has found to foster student learning. In order to complete this study, the researcher documented, through a strategy of reflective practice, his return to teaching high school science after having served for a time as a science specialist and instructional coach. The study develops quality personal insights and questions that may be used by other educators and researchers to investigate the enactment of these different models and strategies. The research is limited to the spring of the 2010 school year and use notes, journals, and planner documents from the 2008--2009 school year. In order to appreciate complex interactions, triangulation was made through dovetailing personal observations with requested observations of the campus assistant principal, the district science specialist, and an out of district observer. Also, a short questionnaire administered to the students in these classes. Throughout this study, the researcher demonstrates that it is feasible to use these models. However, such external factors as imposed curriculum and standardized testing play a large role in everyday decision making of this particular teacher. The sheer amount of content to be covered under the Texas Essential Knowledge and Skills (TEKS) also influenced instructional decisions that were made. Choices about what strategy to use resided mainly within the teacher/researcher and were governed and affected mostly by his interactions with students and professional judgments about what would both bolster student understanding and help students score well on the Texas Assessment of Knowledge and Skills (TAKS).

    In the present paper, the effectiveness of a Sequencing Batch Biofilter Granular Reactor (SBBGR) and its integration with different disinfection strategies (UV irradiation, peracetic acid) for producing an effluent suitable for agricultural use was evaluated. The plant treated raw domestic sewage, and its performances were evaluated in terms of the removal efficiency of a wide group of physical, chemical and microbiological parameters. The SBBGR resulted really efficient in removing suspended solids, COD and nitrogen with an average effluent concentration of 5, 32 and 10 mg/L, respectively. Lower removal efficiency was observed for phosphorus with an average concentration in the effluent of 3 mg/L. Plant effluent was also characterized by an average electrical conductivity and sodium adsorption ratio of 680 μS/cm and 2.9, respectively. Therefore, according to these gross parameters, the SBBGR effluent was conformed to the national standards required in Italy for agricultural reuse. Moreover, disinfection performances of the SBBGR was higher than that of conventional municipal wastewater treatment plants and met the quality criteria suggested by WHO (Escherichia coli<1000 CFU/100 mL) for agricultural reuse. In particular, the biological treatment by SBBGR removed 3.8±0.4 log units of Giardia lamblia, 2.8±0.8 log units of E. coli, 2.5±0.7 log units of total coliforms, 2.0±0.3 log units of Clostridium perfringens, 2.0±0.4 log units of Cryptosporidium parvum and 1.7±0.7 log units of Somatic coliphages. The investigated disinfection processes (UV and peracetic acid) resulted very effective for total coliforms, E. coli and somatic coliphages. In particular, a UV radiation and peracetic acid doses of 40 mJ/cm(2) and 1 mg/L respectively reduced E. coli content in the effluent below the limit for agricultural reuse in Italy (10 CFU/100 mL). Conversely, they were both ineffective on C.perfringens spores.

    Biological phosphorous (P) and nitrogen (N) removal from municipal wastewater was studied using an innovative anoxic-aerobic-anaerobic side-stream treatment system. The impact of influent water quality including chemical oxygen demand (COD), ammonium and orthophosphate concentrations on the reactor performance was evaluated. The results showed the system was very effective at removing both COD (>88%) and NH4(+)-N (>96%) despite varying influent concentrations of COD, NH4(+)-N, and total PO4(3-)-P. In contrast, it was found that the removal of P was sensitive to influent NH4(+)-N and PO4(3-)-P concentrations. The maximum PO4(3-)-P removal of 79% was achieved with the lowest influent NH4(+)-N and PO4(3-)-P concentration. Quantitative PCR (qPCR) assays showed a high abundance and diversity of phosphate accumulating organisms (PAO), nitrifiers and denitrifiers. The MiSeq microbial community structure analysis showed that the Proteobacteria (especially β-Proteobacteria, and γ-Proteobacteria) were the dominant in all reactors. Further analysis of the bacteria indicated the presence of diverse PAO genera including Candidatus Accumulibacter phosphatis, Tetrasphaera, and Rhodocyclus, and the denitrifying PAO (DPAO) genus Dechloromonas. Interestingly, no glycogen accumulating organisms (GAOs) were detected in any of the reactors, suggesting the advantage of proposed process in term of PAO selection for enhanced P removal compared with conventional main-stream processes.

    Overexpression of the human MYCN oncogene driven by a tyrosine hydroxylase promoter causes tumours in transgenic mice that recapitulate the childhood cancer neuroblastoma. To establish an in vitro model to study this process, a series of isogenic cell lines were developed from these MYCN-driven murine tumours. Lines were established from tumours arising in homozygous and hemizygous MYCN transgenic mice. Hemizygous tumours gave rise to cell lines growing only in suspension. Homozygous tumours gave rise to similar suspension lines as well as morphologically distinct substrate-adherent lines characteristic of human S-type neuroblastoma cells. FISH analysis demonstrated selective MYCN transgene amplification in cell lines derived from hemizygous mice. Comparative genomic hybridisation (CGH) and fluorescence in situ hybridisation (FISH) analysis confirmed a range of neuroblastoma-associated genetic changes in the various lines, in particular, gain of regions syntenic with human 17q. These isogenic lines together with the transgenic mice thus represent valuable models for investigating the biological characteristics of aggressive neuroblastoma.

    A new analytical approach, based on micro-transflection measurements from a diamond-coated metal sampling stick, is presented for the analysis of painting varnishes. Minimally invasive sampling is performed from the varnished surface using the stick, which is directly used as a transflection substrate for micro Fourier transform infrared (FTIR) measurements. With use of a series of varnished model paints, the micro-transflection method has been proved to be a valuable tool for the identification of surface components thanks to the selectivity of the sampling, the enhancement of the absorbance signal, and the easier spectral interpretation because the profiles are similar to transmission mode ones. Driven by these positive outcomes, the method was then tested as tool supporting noninvasive reflection FTIR spectroscopy during the assessment of varnish removal by solvent cleaning on paint models. Finally, the integrated analytical approach based on the two reflection methods was successfully applied for the monitoring of the cleaning of the sixteenth century painting Presentation in the Temple by Vittore Carpaccio.

    One of the remarkable aspects of the tremendous biodiversity found in tropical forests is the wide range of evolutionary strategies that have produced this diversity, indicating many paths to diversification. We compare two diverse groups of trees with profoundly different biologies to discover whether these differences are reflected in their genomes. Ficus (Moraceae), with its complex co-evolutionary relationship with obligate pollinating wasps, produces copious tiny seeds that are widely dispersed. Lithocarpus (Fagaceae), with generalized insect pollination, produces large seeds that are poorly dispersed. We hypothesize that these different reproductive biologies and life history strategies should have a profound impact on the basic properties of genomic divergence within each genus. Using shallow whole genome sequencing for six species of Ficus, seven species of Lithocarpus, and three outgroups, we examined overall genomic diversity, how it is shared among the species within each genus, and the fraction of this shared diversity that agrees with the major phylogenetic pattern. A substantially larger fraction of the genome is shared among species of Lithocarpus, a considerable amount of this shared diversity was incongruent with the general background history of the genomes, and each fig species possessed a substantially larger fraction of unique diversity than Lithocarpus.

    Highly ionizing radiation (HZE) in space is considered as main factor causing biological effects. Radiobiological studies during space flights are unrepeatable due to the variable space radiation environment, ground-base ion radiations are usually performed to simulate of the space biological effect. Spaceflights present a low-dose rate (0.1˜~0.3mGy/day) radiation environment inside aerocrafts while ground-base ion radiations present a much higher dose rate (100˜~500mGy/min). Whether ground-base ion radiation can reflect effects of space radiation is worth of evaluation. In this research, we compared the functional proteomic profiles of rice plants between on-ground simulated HZE particle radiation and spaceflight treatments. Three independent ground-base seed ionizing radiation experiments with different cumulative doses (dose range: 2˜~20000mGy) and different liner energy transfer (LET) values (13.3˜~500keV/μμm) and two independent seed spaceflight experiments onboard Chinese 20th satellite and SZ-6 spacecraft were carried out. Alterations in the proteome were analyzed by two-dimensional difference gel electrophoresis (2-D DIGE) with MALDI-TOF/TOF mass spectrometry identifications. 45 and 59 proteins showed significant (p<0.05) and reproducible quantitative differences in ground-base ion radiation and spaceflight experiments respectively. The functions of ground-base radiation and spaceflight proteins were both involved in a wide range of biological processes. Gene Ontology enrichment analysis further revealed that ground-base radiation responsive proteins were mainly involved in removal of superoxide radicals, defense response to stimulus and photosynthesis, while spaceflight responsive proteins mainly participate in nucleoside metabolic process, protein folding and phosphorylation. The results implied that ground-base radiations cannot truly reflect effects of spaceflight radiations, ground-base radiation was a kind of indirect effect to rice causing

  16. Transforming beliefs and practices: Elementary teacher candidates' development through shared authentic teaching and reflection experiences within an innovative science methods course

    NASA Astrophysics Data System (ADS)

    Naidoo, Kara

    Elementary teachers are criticized for failing to incorporate meaningful science instruction in their classrooms or avoiding science instruction altogether. The lack of adequate science instruction in elementary schools is partially attributed to teacher candidates' anxiety, poor content and pedagogical preparation, and low science teaching self-efficacy. The central premise of this study was that many of these issues could be alleviated through course modifications designed to address these issues. The design tested and presented here provided prospective elementary educators' authentic science teaching experiences with elementary students in a low-stakes environment with the collaboration of peers and science teacher educators. The process of comprehensive reflection was developed for and tested in this study. Comprehensive reflection is individual and collective, written and set in dialogic discourse, focused on past and future behavior, and utilizes video recordings from shared teaching experiences. To test the central premise, an innovative science methods course was designed, implemented and evaluated using a one-group mixed-method design. The focus of the analysis was on changes in self-efficacy, identity and teaching practices as a function of authentic science teaching experiences and comprehensive reflection. The quantitative tools for analysis were t-tests and repeated-measures ANOVA on the Science Teaching Efficacy Belief Instrument-B (STEBI-B) and weekly self-rating on confidence as a learner and a teacher of science, respectively. The tools used to analyze qualitative data included thematic analysis and interpretative phenomenological analysis. In addition, theoretically grounded tools were developed and used in a case study to determine the ways one prospective educator's science teaching identity was influenced by experiences in the course. The innovative course structure led the development of teacher candidates' science teaching identity

  17. Focused beam reflectance method as an innovative (PAT) tool to monitor in-line granulation process in fluidized bed.

    Fluidized bed granulation is a commonly used unit operation in the pharmaceutical industry. But still to obtain and control the desired granule size is challenging due to many process variables affecting the final product. Focused beam reflectance measurement (FBRM, Mettler-Toledo, Switzerland) is an increasingly popular particle growth analysis technique. FBRM tool was installed in two different locations inside a fluidized bed granulator (GPCG2, Glatt, Binzen) in order to monitor the granulation growth kinetics. An experimental design was created to study the effect of process variables using FBRM probe and comparing the results with the one's measured by sieve analysis. The probe location is of major importance to get smooth and robust curves. The excess feeding of binder solution might lead to agglomeration and thus to process collapse, however this phenomenon was clearly detected with FBRM method. On the other hand, the process variables at certain levels might affect the FBRM efficiency by blocking the probe window with sticky particles. A good correlation was obtained (R(2) = 0.95) between FBRM and sieve analysis mean particle size. The proposed in-line monitoring tool enables the operator to select appropriate process parameters and control the wet granulation process more efficiently.

    We present in this work a theoretical and conceptual study and some reflections on a fundamental aspect concerning with the structure and brain function: the Cellular Communication. The main interests of our study are the signal transmission mechanisms and the neuronal mechanisms responsible to learning. We propose the consideration of a new kind of communication mechanisms, different to the synaptic transmission, "Diffusion or Volume Transmission." This new alternative is based on a diffusing messenger as nitric oxide (NO). Our study aims towards the design of a conceptual framework, which covers implications of NO in the artificial neural networks (ANNs), both in neural architecture and learning processing. This conceptual frame might be able to provide possible biological support for many aspects of ANNs and to generate new concepts to improve the structure and operation of them. Some of these new concepts are The Fast Diffusion Neural Propagation (FDNP), the Diffuse Neighborhood (DNB), (1), the Diffusive Hybrid Neuromodulation (DHN), the Virtual Weights. Finally we will propose a new mathematical formulation for the Hebb learning law, taking into account the NO effect. Along the same lines, we will reflect on the possibility of a new formal framework for learning processes in ANNs, which consist of slow and fast learning concerning with co-operation between the classical neurotransmission and FDNP. We will develop this work from a computational neuroscience point of view, proposing a global study framework of diffusion messenger NO (GSFNO), using a hybrid natural/artificial approach. Finally it is important to note that we can consider this paper the first paper of a set of scientific work on nitric oxide (NO) and artificial neural networks (ANNs): NO and ANNs Series. We can say that this paper has a character of search and query on both subjects their implications and co-existence.

    drawback for assessing AFC during pregnancy is that transvaginal ultrasound is needed at the 11- to 13-week scan, when the transabdominal approach is used most commonly. Furthermore identifying ovaries by ultrasound during pregnancy could be challenging. Considering that AFC reflects ovarian aging, this 'ovarian biological age' could potentially reflect a more precise background risk of fetal aneuploidy. This study was supported by PI 11/00685.

    Total internal reflection of exciting light, in combination with fluorescence intensity and polarization measurements, was used to selectively study fluorescent compounds adsorbed to the interface region between two immiscible liquids. A fluorometer was constructed which provided excitation at variable angles of incidence and allowed sensitive detection of polarized fluorescence emitted from the interface. The compound 4,4'-bis-1-phenylamino-8-naphthalenesulfonate (bis-ANS) was examined at a decalin/water interface and was found to possess remarkable affinity for the interface region with the bulk of the adsorbed molecule residing in the decalin phase. The adsorbed fluorophore displayed an apparent hindered rotation in the plane of the interface with a rotational diffusion coefficient 3- to 12-fold lower than that expected for bis-ANS in solution. While other dyes examined were not found to be significantly surface active, the addition of cationic surfactant sufficed to induce adsorption of the anionic fluorophore 1-aminonaphthalene-3,6,8-trisulfonic acid. This fluoropore was found to reside in an aqueous environment when bound to the interface, and it also exhibited hindered rotation in the plane of the interface. As the concentrations of the dyes were increased, both adsorbed dyes exhibited polarization reductions consistent with excitation energy transfer. Adsorption of bis-ANS was reversed by addition of bovine serum albumin. The membrane protein cytochrome b5 was found not to bind at the decalin/water interface, indicating that interaction with lipid is required for its adherence to biological membranes. PMID:3651556

    In this study, some mixtures of consolidants or water-repellent products and biocides developed to prevent biological growth, were tested over time on three stone substrates with different bioreceptivity. The performance of both traditional (tetraethylorthosilicate, methylethoxy polysiloxane, Paraloid B72, tributyltin oxide, dibutyltin dilaurate) and innovative compounds (copper nanoparticles) was assessed using colour measurements, the water absorption by contact sponge method, and observation under stereo and optical microscopes. The application of the mixtures had also the purpose of controlling re-colonization on stone after a conservation treatment. The study site was the archaeological Area of Fiesole; the mixtures were applied in situ to sandstone, marble and plaster which had been cleaned beforehand. An innovative aspect of the study is that, by using non-invasive methods, it also permitted monitoring the mixtures' effectiveness in preventing biological growth. The monitoring results made it possible to assess the bioreceptivity of the treated stones (sandstone, marble, plaster) over a period of almost three years. The results showed that the mixtures of consolidants or water-repellent products with biocides were effective in preventing biological growth on both a substrate with low bioreceptivity like plaster and a substrate with high bioreceptivity such as marble. The innovative mixture of nano-Cu particles with a water-repellent yielded good results in terms of preventing biological colonization. Moreover, they apparently did not affect the substrates' colour. Mixtures of nano-Cu particles with a consolidant and a water-repellent hold great promise for preventing re-colonization of stone after conservation treatment. Copyright © 2012 Elsevier B.V.

    Background A core feature of chronic obstructive pulmonary disease (COPD) is the accelerated decline in forced expiratory volume in one second (FEV1). The recent Groningen and Leiden Universities study of Corticosteroids in Obstructive Lung Disease (GLUCOLD) study suggested that particular phenotypes of COPD benefit from fluticasone±salmeterol by reducing the rate of FEV1 decline, yet the underlying mechanisms are unknown. Methods Whole-genome gene expression profiling using the Affymetrix Gene ST array (V.1.0) was performed on 221 bronchial biopsies available from 89 COPD patients at baseline and after 6 and 30 months of fluticasone±salmeterol and placebo treatment in GLUCOLD. Results Linear mixed effects modelling revealed that the expression of 138 genes decreased, whereas the expression of 140 genes significantly upregulated after both 6 and 30 months of treatment with fluticasone±salmeterol versus placebo. A more pronounced treatment-induced change in the expression of 50 and 55 of these 278 genes was associated with a lower rate of decline in FEV1 and Saint George Respiratory Questionnaire, respectively. Genes decreasing with treatment were involved in pathways related to cell cycle, oxidative phosphorylation, epithelial cell signalling, p53 signalling and T cell signalling. Genes increasing with treatment were involved in pathways related to focal adhesion, gap junction and extracellular matrix deposition. Finally, the fluticasone-induced gene expression changes were enriched among genes that change in the airway epithelium in smokers with versus without COPD in an independent data set. Conclusions The present study suggests that gene expression in biological pathways of COPD is dynamic with treatment and reflects disease activity. This study opens the gate to targeted and molecular phenotype-driven therapy of COPD. PMID:23925644

  5. Analogical reflection as a source for the science of life: Kant and the possibility of the biological sciences.

    PubMed

    Nassar, Dalia

    2016-08-01

    In contrast to the previously widespread view that Kant's work was largely in dialogue with the physical sciences, recent scholarship has highlighted Kant's interest in and contributions to the life sciences. Scholars are now investigating the extent to which Kant appealed to and incorporated insights from the life sciences and considering the ways he may have contributed to a new conception of living beings. The scholarship remains, however, divided in its interest: historians of science are concerned with the content of Kant's claims, and the ways in which they may or may not have contributed to the emerging science of life, while historians of philosophy focus on the systematic justifications for Kant's claims, e.g., the methodological and theoretical underpinnings of Kant's statement that living beings are mechanically inexplicable. My aim in this paper is to bring together these two strands of scholarship into dialogue by showing how Kant's methodological concerns (specifically, his notion of reflective judgment) contributed to his conception of living beings and to the ontological concern with life as a distinctive object of study. I argue that although Kant's explicit statement was that biology could not be a science, his implicit and more fundamental claim was that the study of living beings necessitates a distinctive mode of thought, a mode that is essentially analogical. I consider the implications of this view, and argue that it is by developing a new methodology for grasping organized beings that Kant makes his most important contribution to the new science of life.

  7. Discovery of Innovative Therapies for Rare Immune-Mediated Inflammatory Diseases via Off-Label Prescription of Biologics: The Case of IL-6 Receptor Blockade in Castleman's Disease.

    PubMed

    2015-01-01

    Biologics have revolutionized the field of clinical immunology and proven to be both effective and safe in common immune-mediated inflammatory diseases (IMIDs) such as rheumatoid arthritis, inflammatory bowel diseases, and various hematological disorders. However, in patients with rare, severe IMIDs failing on standard therapies, it is virtually impossible to conduct randomized controlled trials. Therefore, biologics are usually prescribed off-label in these often severely ill patients. Unfortunately, off-label prescription is sometimes hampered in these diseases due to a lack of reimbursement that is often based on a presumed lack of evidence for effectiveness. In the present article, we will discuss that off-label prescription of biologics can be a good way to discover new treatments for rare diseases. This will be illustrated using a case of multicentric Castleman's disease, an immune-mediated lymphoproliferative disorder, in which off-label tocilizumab (humanized anti-IL-6 receptor blocking antibody) treatment resulted in remarkable clinical improvement. Furthermore, we will give recommendations for monitoring efficacy and safety of biologic treatment in rare IMIDs, including the use of registries. In conclusion, we put forward that innovative treatments for rare IMIDs can be discovered via off-label prescription of biologicals, provided that this is based on rational arguments including knowledge of the pathophysiology of the disease.

    Aim To compare the population group from the Šopot graveyard with population groups from traditional Croatian medieval graveyards by using anthropological, craniometrics, and mitochondrial (mtDNA) analysis and to examine if the cultural differences between population groups reflect biological differences. Methods We determined sex, age at death, pathological, and traumatic changes of skeletal remains from the Šopot graveyard and compared them with a cumulative medieval sample from the same region. We also performed principal component analysis to compare skeletal remains from Šopot with those from Ostrovica and other Central European samples according to 8 cranial measurements. Finally, we compared 46 skeletons from Šopot with medieval (Ostrovica) and contemporary populations using mDNA haplogroup profiling. Results The remains from Šopot were similar to the cumulative sample in lifestyle and quality of life markers. Principal component analysis showed that they were closely related to Eastern Adriatic coast sites (including Ostrovica and Šopot) in terms of cranial morphology, indicating similar biological makeup. According to mDNA testing, Šopot population showed no significant differences in the haplogroup prevalence from either medieval or contemporary populations. Conclusion This study shows that the Šopot population does not significantly differ from other medieval populations from this area. Besides similar quality of life markers, these populations also had similar biological markers. Substantial archeological differences can therefore be attributed to apparent cultural influences, which in this case do not reflect biological differences. PMID:26088847

  12. Prospective Technology Assessment of Synthetic Biology: Fundamental and Propaedeutic Reflections in Order to Enable an Early Assessment.

    2016-08-01

    Synthetic biology is regarded as one of the key technosciences of the future. The goal of this paper is to present some fundamental considerations to enable procedures of a technology assessment (TA) of synthetic biology. To accomplish such an early "upstream" assessment of a not yet fully developed technology, a special type of TA will be considered: Prospective TA (ProTA). At the center of ProTA are the analysis and the framing of "synthetic biology," including a characterization and assessment of the technological core. The thesis is that if there is any differentia specifica giving substance to the umbrella term "synthetic biology," it is the idea of harnessing self-organization for engineering purposes. To underline that we are likely experiencing an epochal break in the ontology of technoscientific systems, this new type of technology is called "late-modern technology." -I start this paper by analyzing the three most common visions of synthetic biology. Then I argue that one particular vision deserves more attention because it underlies the others: the vision of self-organization. I discuss the inherent limits of this new type of late-modern technology in the attempt to control and monitor possible risk issues. I refer to Hans Jonas' ethics and his early anticipation of the risks of a novel type of technology. I end by drawing conclusions for the approach of ProTA towards an early societal shaping of synthetic biology.

    Currently, no doctoral guidelines to teach innovation exist. Using Christensen's theory of disruptive innovation, the five discovery skills used by disruptive innovators provide the framework for designing a leadership development approach to enable and support a mindset to innovate. Executive leadership students were provided with didactic content on innovation, were assigned to non-healthcare settings for an anthropological dig to uncover innovative activities, and were provided with reflective prompts to enable a new context for innovation. Faculty collaborated with other fields and took risks to provide new contexts to innovate. Students identified and proposed innovations for current health care issues. Some of the innovations included processes, evaluation methods, data analytics for care design, and patient engagement solutions. Faculty crossed borders for field experiences, as well as disciplinary borders. This collaborative seminar demonstrated that it is possible to develop executive nurse leaders to innovate.

    Influenza represents a serious threat to public health with thousands of deaths each year. A deeper understanding of the host-pathogen interactions is urgently needed to evaluate individual and population risks for severe influenza disease and to identify new therapeutic targets. Here, we review recent progress in large scale omics technologies, systems genetics as well as new mathematical and computational developments that are now in place to apply a systems biology approach for a comprehensive description of the multidimensional host response to influenza infection. In addition, we describe how results from experimental animal models can be translated to humans, and we discuss some of the future challenges ahead.

    The aim of this study was to develop a formulation, containing the propolis standardized extract (EPP-AF®), which can assist in the healing of skin lesions. To achieve this objective the antimicrobial activity and chemical composition of the propolis extract was determined. The final product was subjected to in vitro and in vivo pre-clinical evaluation. The broth macrodilution method was used to determine the antimicrobial activity of the extracts and formulations against the microorganisms most commonly found in burns, Pseudomonas aeruginosa, Klebsiella pneumoniae, Escherichia coli, Staphylococcus aureus and Staphylococcus epidermidis. Wistar rats with puncture wounded skin were used to evaluate the wound healing properties of propolis. The results of chemical and biological characterization demonstrated the batch-to-batch reproducibility of the standardized extract which is an unprecedented result. The antimicrobial and wound healing activity of the pharmaceutical studied showed the best results when samples contain 3.6% propolis, suggesting that this is the most promising composition.

    2004-08-01

    The basic reproductive biology of two ectoparasitoids developing on the late larval instars of the scolytid Ips typographus Linnaeus, a pest of spruce forests in Eurasia, was studied with the purpose of explaining which biological features allow the two species to share the same host. The anautogenous braconid Coeloides bostrichorum Giraud had a longer pre-oviposition period (5.1 vs. 3.3 days), a greater egg load (8.1 vs. 6.1 eggs), survived longer and emerged later than the pteromalid Rhopalicus tutela (Walker). In contrast, R. tutela was autogenous and tended to be more fecund under constrained conditions (9.7 vs. 5.1 total offspring per female). The longer pre-oviposition period of the specialist C. bostrichorum, coupled with its greater longevity, afforded the opportunity of better synchronization of ovipositing females with late instar larvae of I. typographus. By contrast, the polyphagous R. tutela matured rapidly, allowing parasitism of both younger and older larval instars of I. typographus in addition to other species. These small differences favoured the co-occurrence of the two parasitoid species on the same attacked trees.

  19. On the renormalisation of the diffusion asymptotics in the problem of reflection of a narrow optical beam from a biological medium

    Appanov, A Yu; Barabanenkov, Yu N

    2005-12-31

    An analytic hybrid method is considered for solving the stationary radiation transfer equation in the problem on reflection of a narrow laser beam from biological media such as the 2% aqueous solution of intralipid and erythrocyte suspension with the volume concentration (hematocrit) H=0.41. The method is based on the reciprocity of the Green function in the radiation transfer theory and on the iteration solution of the integral equation for this function. As a result, the ray intensity is represented as a sum of two terms. The first of them describes the contribution of finite-order scattering to the intensity of a beam diffusely reflected from the medium. The second term contains the explicit analytic expression for a spatially distributed effective source of diffuse radiation emerging from the deep layers of the medium to the surface. This approach substantially improves the diffusion approximation for the problem under study and allows one to obtain the uniform asymptotics of the reflection coefficient at the specified interval of distances between the radiation source and detector on the medium surface with the relative error within {+-}6% for the 2% intralipid emulsion and erythrocyte suspension (H=0.41).

    2015-01-01

    Current research considers wastewater as a source of energy, nutrients and water and not just a source of pollution. So far, mainly energy intensive physical and chemical unit processes have been developed to recover some of these resources, and less energy and resource demanding alternatives are needed. Here, we present a modified enhanced biological phosphorus removal and recovery system (referred to as EBP2R) that can produce optimal culture media for downstream micro-algal growth in terms of N and P content. Phosphorus is recovered as a P-stream by diversion of some of the effluent from the upstream anaerobic reactor. By operating the process at comparably low solids retention times (SRT), the nitrogen content of wastewater is retained as free and saline ammonia, the preferred form of nitrogen for most micro-algae. Scenario simulations were carried out to assess the capacity of the EBP2R system to produce nutrient rich organic-carbon depleted algal cultivation media of target composition. Via SRT control, the quality of the constructed cultivation media can be optimized to support a wide range of green micro-algal growth requirements. Up to 75% of the influent phosphorus can be recovered, by diverting 30% of the influent flow as a P-stream at an SRT of 5 days. Through global sensitivity analysis we find that the effluent N-to-P ratio and the P recovered are mainly dependent on the influent quality rather than on biokinetics or stoichiometry. Further research is needed to demonstrate that the system performance predicted through the model-based design can be achieved in reality. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Rhabdomyosarcoma (RMS) and Ewing sarcoma (ES) are among the most common pediatric sarcomas (Arndt et al., 2012). Despite sarcomas representing a highly heterogeneous group of tumors, ES and alveolar RMS (ARMS) typically share one common genetic characteristic, namely a specific chromosomal translocation (Helman and Meltzer, 2003; Lessnick and Ladanyi, 2012). These translocations generate fusion proteins, which are composed of two transcription factors (TF). Typically, one TF is a developmentally regulated factor that is essential for proper specification of a given lineage and provides the DNA-binding domain, while the partner TF contributes a transactivation domain that drives aberrant expression of target genes. Based on these common genetic characteristics, the first ESF-EMBO research conference entitled "Molecular Biology and Innovative Therapies in Sarcomas of Childhood and Adolescence" with special focus on RMS and ES was held at the Polonia Castle in Pultusk, Poland. The conference gathered 70 participants from more than 15 countries and several continents representing most research groups that are active in this field.

    This study examined the reflection interview as a tool for assessing and facilitating the use of 'systems language' amongst 11th grade students who have recently completed their first year of high school biology. Eighty-three students composed two concept maps in the 10th grade-one at the beginning of the school year and one at its end. The first part of the interview is dedicated to guiding the students through comparing their two concept maps and by means of both explicit and non-explicit teaching. Our study showed that the explicit guidance in comparing the two concept maps was more effective than the non-explicit, eliciting a variety of different, more specific, types of interactions and patterns (e.g. 'hierarchy', 'dynamism', 'homeostasis') in the students' descriptions of the human body system. The reflection interview as a knowledge integration activity was found to be an effective tool for assessing the subjects' conceptual models of 'system complexity', and for identifying those aspects of a system that are most commonly misunderstood.

    Ingenol mebutate represents a topical treatment for fields with actinic keratosis (AK). The biological effects of ingenol mebutate in AK, subclinical (SC)-AK, and reference-skin were assessed and graded by in vivo reflectance confocal microscopy (RCM) and histology. Patients with AK and SC-AK lesions in one 25 cm2 field on hands or forearms, and with an area of reference skin on the inner upper arm, were included. The two fields were each treated with ingenol mebutate 0.05% gel (n=16), or vehicle (n=8), on 2 consecutive days; clinical and RCM assessments were performed on days 1, 2, 3, 8, and 57, and biopsies on day 3. Local skin responses were more pronounced in AK fields (6.1 (mean) ± 2.6 (SD)) compared with reference skin (3.5 ± 1.5). The clinical AK lesion reduction was 43.8% and 6.3% with ingenol mebutate and vehicle, respectively. RCM and histology evaluations showed that ingenol mebutate induced a significant pronounced cell death and immune response in AK and SC-AK lesions, compared with reference skin. Ingenol mebutate induced RCM-measured reduction in (investigator-1/investigator-2): AK lesions (34/28%), SC-AK lesions (72/56%), and solar elastosis in AK fields (mean, -0.22/-0.25). In conclusion, ingenol mebutate showed selective pronounced biological responses in AK and SC-AK as compared with reference skin.

    Excavations at the 14th century Moorish rampart (Granada, Spain) unearthed a brick oven alongside black ash and bone stratigraphic layers. In situ evidence suggests the oven served to fabricate a wall coating including powdered burnt bones. Original ad hoc analyses improved on conventional methods were used to confirm this hypothesis. These methods enable (i) nondestructive micro-X-ray diffraction (mu-XRD) for fast mineralogical data acquisition (approximately 10 s) and moderately high spatial (approximately 500 microm) resolution and (ii) identification and imaging of crystalline components in sample cross-sections via mineral maps, yielding outstanding visualization of grain distribution and morphology in composite samples based on scanning electron microscopy-energy dispersion X-ray spectrometry (SEM-EDX) elemental maps. Benefits are shown for applying diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) vs transmittance-FT-IR (T-FT-IR) to analyze organic and inorganic components in single samples. Complementary techniques to fully characterize artifacts were gas chromatography/mass spectroscopy (GC/MS), optical microscopy (OM), conventional powder XRD, and (14)C dating. Bone-hydroxyapatite was detected in the coating. Mineralogical transformations in the bricks indicate oven temperatures well above 1000 degrees C, supporting the hypothesis.

    When considering opportunities to develop novel, eye-catching and consumer-relevant personal care (PC) products, it is important to understand and reflect on how science has changed over the last two decades and how this has generated a new body of data from which to draw ideas and technologies. This article outlines some advances in scientific technologies and new ways of thinking in science, which lead to new insights into skin biology. How these innovations may impact and be leveraged into the development of new products in PC is also discussed. For example, fundamental discoveries in skin biology and the advancement of scientific methodologies are enabling step changes in technology in PC. Two examples of areas where we have seen much advancement are discussed.

    Kanter, Rosabeth Moss

    2006-11-01

    Never a fad, but always in or out of fashion, innovation gets rediscovered as a growth enabler every half dozen years. Too often, though, grand declarations about innovation are followed by mediocre execution that produces anemic results, and innovation groups are quietly disbanded in cost-cutting drives. Each managerial generation embarks on the same enthusiastic quest for the next new thing. And each generation faces the same vexing challenges- most of which stem from the tensions between protecting existing revenue streams critical to current success and supporting new concepts that may be crucial to future success. In this article, Harvard Business School professor Rosabeth Moss Kanter reflects on the four major waves of innovation enthusiasm she's observed over the past 25 years. She describes the classic mistakes companies make in innovation strategy, process, structure, and skills assessment, illustrating her points with a plethora of real-world examples--including AT&T Worldnet, Timberland, and Ocean Spray. A typical strategic blunder is when managers set their hurdles too high or limit the scope of their innovation efforts. Quaker Oats, for instance, was so busy in the 1990s making minor tweaks to its product formulas that it missed larger opportunities in distribution. A common process mistake is when managers strangle innovation efforts with the same rigid planning, budgeting, and reviewing approaches they use in their existing businesses--thereby discouraging people from adapting as circumstances warrant. Companies must be careful how they structure fledgling entities alongside existing ones, Kanter says, to avoid a clash of cultures and agendas--which Arrow Electronics experienced in its attempts to create an online venture. Finally, companies commonly undervalue and underinvest in the human side of innovation--for instance, promoting individuals out of innovation teams long before their efforts can pay off. Kanter offers practical advice for avoiding

    There is a large body of work that documents the history of the nursing profession and the experiences of nurses during significant historical eras such as the First World War. Yet learning about nursing history is commonly a tiny, or absent, component in the undergraduate nursing curriculum. This paper discusses an innovative project that had multiple aims. A primary aim was to engage nursing students and educators in a project that valued nursing history by integrating it into an event to celebrate International Nurses Day. As the paper will explain, other aims were in organising the event so that it capitalised on particular creative arts strengths within the faculty, offering cross-disciplinary connections, engagement and appreciation. A Readers' Theatre event, involving academics and students in nursing, creative arts and education, was conceived, developed and performed for the community. The theme was the experiences of First World War nurses and how they encapsulated values important to nursing today - the 6 Cs - which guide high standards of nursing. The 6 Cs are care, compassion, competence, communication, courage and commitment. We called the Readers' Theatre "The Courage to Care", and this involved a 4month process of script development, event planning and a performance. This process and outcomes were evaluated, prompting a reflection on the strengths and challenges of working in this creative way to engage a wide group of stakeholders to advance the profession of nursing.

    Half-heartedly acknowledged by the Russian Federation, the Soviet Union ran the world's largest offensive program for biological weapons, breaching the Biological and Toxin Weapons Convention. Russia criminalized biological weapons in 1993 only to decriminalize them in 1996, but in 2003 president Putin partly recriminalized them. None of these changes were declared within the Convention. Several well-known official statements, when reviewed in their context, turned out to admit to neither an offensive program nor a breach of the Convention. Thus, the Russian biological weapons policy is more ambiguous than usually depicted, and various policy shapers can be discerned.

    Sequencing the human genome began in 1994, and 10 years of work were necessary in order to provide a nearly complete sequence. Nowadays, NGS technologies allow sequencing of a whole human genome in a few days. This deluge of data challenges scientists in many ways, as they are faced with data management issues and analysis and visualization drawbacks due to the limitations of current bioinformatics tools. In this paper, we describe how the NGS Big Data revolution changes the way of managing and analysing data. We present how biologists are confronted with abundance of methods, tools, and data formats. To overcome these problems, focus on Big Data Information Technology innovations from web and business intelligence. We underline the interest of NoSQL databases, which are much more efficient than relational databases. Since Big Data leads to the loss of interactivity with data during analysis due to high processing time, we describe solutions from the Business Intelligence that allow one to regain interactivity whatever the volume of data is. We illustrate this point with a focus on the Amadea platform. Finally, we discuss visualization challenges posed by Big Data and present the latest innovations with JavaScript graphic libraries.

    The Innovance VWF:Ac test (Siemens) has the particularity to assess the binding capacity of von Willebrand factor (VWF) to recombinant platelet GPIb mutated in the absence of ristocetin. Our study aimed to evaluate and validate according to standard NF EN ISO 15189 the original protocol adaptation on STA-R Evolution series analyser (Diagnostica Stago). We evaluated the performance in terms of imprecision and we validate additional parameters necessary in range B as recommended by the SH GTA 04 (Cofrac). We compared the new assay with the reference assay: ristocetin cofactor activity (VWF:RCo) performed on the BCS-XP analyser by testing retrospectively samples from 82 healthy normal subjects and 61 patients with von Willebrand disease (VWD). This new assay is consistent with objectives set in terms of imprecision with CV around 4%. Excepted limit of quantification higher, additional parameters evaluated in range B have been validated. The Innovance VWF: Ac assay allowed the detection of all deficits of VWF already detected by the VWF:RCo test on the BCS-XP. This adjustment on STA-R analyser therefore has satisfactory analytical performance criteria. Apart from the limit of quantification, this reagent can be used according to the recommendations specified in the original protocol adaptation. Its performance and compatibility with the spot measurement allow the diagnosis and therapeutic monitoring of VWD according to current requirements and guidelines.

    Abstract In recent years, rapid developments in several omics platforms and next generation sequencing technology have generated a huge amount of biological data about plants. Systems biology aims to develop and use well-organized and efficient algorithms, data structure, visualization, and communication tools for the integration of these biological data with the goal of computational modeling and simulation. It studies crop plant systems by systematically perturbing them, checking the gene, protein, and informational pathway responses; integrating these data; and finally, formulating mathematical models that describe the structure of system and its response to individual perturbations. Consequently, systems biology approaches, such as integrative and predictive ones, hold immense potential in understanding of molecular mechanism of agriculturally important complex traits linked to agricultural productivity. This has led to identification of some key genes and proteins involved in networks of pathways involved in input use efficiency, biotic and abiotic stress resistance, photosynthesis efficiency, root, stem and leaf architecture, and nutrient mobilization. The developments in the above fields have made it possible to design smart crops with superior agronomic traits through genetic manipulation of key candidate genes. PMID:26484978

    From understanding ageing to the creation of artificial membrane-bounded 'organisms', systems biology and synthetic biology are seen as the latest revolutions in the life sciences. They certainly represent a major change of gear, but paradigm shifts? This is open to debate, to say the least. For scientists they open up exciting ways of studying living systems, of formulating the 'laws of life', and the relationship between the origin of life, evolution and artificial biological systems. However, the ethical and societal considerations are probably indistinguishable from those of human genetics and genetically modified organisms. There are some tangible developments just around the corner for society, and as ever, our ability to understand the consequences of, and manage, our own progress lags far behind our technological abilities. Furthermore our educational systems are doing a bad job of preparing the next generation of scientists and non-scientists.

    Skin hydration is defined as the water content of the epidermis and the dermis. In vivo reflectance confocal microscopy offers the opportunity to determine in vivo the kinetics of the skin after the application of topical products. To define confocal features associated with dry skin and assess the microscopic effects of different moisturizers. Ten healthy volunteers were enrolled for the study. Two different formulations were tested: petrolatum and a commercially available emulsion. Measurements were performed from baseline to 3 h after removal of the occlusion at regular time points. Nine confocal features were assessed: furrows' size, overall interkeratinocyte reflectance, furrows' morphology, scales, skin surface irregularity, non-rimmed dermal papillae, exocytosis, dermal inflammation and collagen type. Furrows' size and interkeratinocyte reflectance were also quantitated using a digital analysis. Stratum corneum capacitance was recorded. At baseline, RCM showed the presence of micro-scales and high skin surface irregularity score. After the application of topical products, the scale score decreased significantly; Furrow's size and Digital Furrow's Size had a marked and directly correlated decrement. Furrow's morphology and Epidermal Irregularity scores decreased from baseline to 30 min, the latter reaching a plateau in product application areas. Interestingly, interkeratinocyte reflectance progressively increased with the application of the topical products, while remained stable in the control area, confirmed by Digital Interkeratinocytes reflectance quantitation. RCM revealed that the changes involve the skin surface by reducing the micro-scales and epidermal irregularity. Even more interestingly, RCM showed that higher interkeratinocytes' brightness is seen for moisturizer, but not for the control area. This RCM finding could be linked to keratinocyte membrane protein exposure and/or substance release in the interkeratinocytic space. To sum up, RCM

    Technological changes and need for innovation represents the main concerns for organizational growth and profitability. However the main priority is still about achieving high performance through product development and consumers' engagement activities. As implementation of open innovation applications increased and value co — creation became well known and major process, companies were engaged into value co — innovation activities. From this point of view the need for joint efforts with consumers in product development arose. Thus the primary condition for an organization to be consumer centric is to define clear the vision and mission which reflects the common efforts for co — creation and diffusion of innovation. As Research & Development processes evolved and interest for innovative concepts and products arose, companies started to implement the specific instruments for consumers' attraction and engagement into design and product development. The digitalized innovation became the main source for establishing the direct communication with the consumers. In order to achieve organization growth, profitability and recognition, the companies should be aware of the innovation importance and the need for internal change. From this point of view, there is necessary to assess the organizational structures, to implement new policies and to establish strategic targets. Basically it is justified the need for platform occurrence and development. Based on case study of BMW Group, recognised leader in automotive industry for innovative concepts, there will be analysed main features within organizational context which promotes the innovation implementation. There will be provided the review of the BMW Group experience of innovation activities, main consumers' engagement strategies, the values which promote the consumer — centric product development, new opportunities assessment, major policies and concerns. The foreseen result is to understand how companies are

  6. Innovations in Proteomic Profiling of Cancers: Alternative Splice Variants as a New Class of Cancer Biomarker Candidates and Bridging of Proteomics with Structural Biology

    PubMed Central

    Omenn, Gilbert S.; Menon, Rajasree; Zhang, Yang

    2013-01-01

    Alternative splicing allows a single gene to generate multiple RNA transcripts which can be translated into functionally diverse protein isoforms. Current knowledge of splicing is derived mainly from RNA transcripts, with very little known about the expression level, 3D structures, and functional differences of the proteins. Splicing is a remarkable phenomenon of molecular and biological evolution. Studies which simply report up-regulation or down-regulation of protein or mRNA expression are confounded by the effects of mixtures of these isoforms. Besides understanding the net biological effects of the mixtures, we may be able to develop biomarker tests based on the observable differential expression of particular splice variants or combinations of splice variants in specific disease states. Here we review our work on differential expression of splice variant proteins in cancers and the feasibility of integrating proteomic analysis with structure-based conformational predictions of the differences between such isoforms.

    Reflective writing (RW) curriculum initiatives to promote reflective capacity are proliferating within medical education. The authors developed a new evaluative tool that can be effectively applied to assess students' reflective levels and assist with the process of providing individualized written feedback to guide reflective capacity promotion. Following a comprehensive search and analysis of the literature, the authors developed an analytic rubric through repeated iterative cycles of development, including empiric testing and determination of interrater reliability, reevaluation and refinement, and redesign. Rubric iterations were applied in successive development phases to Warren Alpert Medical School of Brown University students' 2009 and 2010 RW narratives with determination of intraclass correlations (ICCs). The final rubric, the Reflection Evaluation for Learners' Enhanced Competencies Tool (REFLECT), consisted of four reflective capacity levels ranging from habitual action to critical reflection, with focused criteria for each level. The rubric also evaluated RW for transformative reflection and learning and confirmatory learning. ICC ranged from 0.376 to 0.748 for datasets and rater combinations and was 0.632 for the final REFLECT iteration analysis. The REFLECT is a rigorously developed, theory-informed analytic rubric, demonstrating adequate interrater reliability, face validity, feasibility, and acceptability. The REFLECT rubric is a reflective analysis innovation supporting development of a reflective clinician via formative assessment and enhanced crafting of faculty feedback to reflective narratives.

    New ideas are the precious currency of the new economy, but generating them doesn't have to be a mysterious process. The image of the lone genius inventing from scratch is a romantic fiction. Businesses that constantly innovate have systematized the production and testing of new ideas, and the system can be replicated by practically any organization. The best innovators use old ideas as the raw materials for new ideas, a strategy the authors call knowledge brokering. The system for sustaining innovation is the knowledge brokering cycle, and the authors discuss its four parts. The first is capturing good ideas from a wide variety of sources. The second is keeping those ideas alive by playing with them, discussing them, and using them. Imagining new uses for old ideas is the third part--some knowledge brokers encourage cross-pollination by creating physical layouts that allow, or even force, people to interact with one another. The fourth is turning promising concepts into real services, products, processes, or business models. Companies can use all or part of the cycle. Large companies in particular desperately need to move ideas from one place to another. Some will want to build full-fledged consulting groups dedicated to internal knowledge brokering. Others can hire people who have faced problems similar to the companies' current problems. The most important lesson is that business leaders must change how they think about innovation, and they must change how their company cultures reflect that thinking.

    Abstract Dengue virus infects millions of people worldwide, and there is no vaccine or anti-dengue therapeutic available. Antimicrobial peptides have been shown to possess effective antiviral activity against various viruses. One of the main limitations of developing these peptides as potent antiviral drugs is the high cost of production. In this study, high yield production of biologically active plectasin peptide was inexpensively achieved by producing tandem plectasin peptides as inclusion bodies in E. coli. Antiviral activity of the recombinant peptide towards dengue serotype-2 NS2B-NS3 protease (DENV2 NS2B-NS3pro) was assessed as a target to inhibit dengue virus replication in Vero cells. Single units of recombinant plectasin were collected after applying consecutive steps of refolding, cleaving by Factor Xa, and nickel column purification to obtain recombinant proteins of high purity. The maximal nontoxic dose (MNTD) of the recombinant peptide against Vero cells was 20 μM (100 μg/mL). The reaction velocity of DENV2 NS2B-NS3pro decreased significantly after increasing concentrations of recombinant plectasin were applied to the reaction mixture. Plectasin peptide noncompetitively inhibited DENV2 NS2B-NS3pro at Ki value of 5.03±0.98 μM. The percentage of viral inhibition was more than 80% at the MNTD value of plectasin. In this study, biologically active recombinant plectasin which was able to inhibit dengue protease and viral replication in Vero cells was successfully produced in E. coli in a time- and cost- effective method. These findings are potentially important in the development of potent therapeutics against dengue infection. PMID:24044366

    This paper describes and discusses the impacts of the passage of cold fronts on the vertical structure of the Carlos Botelho (Lobo-Broa) Reservoir as demonstrated by changes in physical, chemical, and biological variables. The data were obtained with a continuous system measuring 9 variables in vertical profiles in the deepest point of the reservoir (12 m) coupled with climatological information and satellite images, during a 32-day period in July and August, 2003. During periods of incidence of cold fronts the reservoir presented vertical mixing. After the dissipation of the cold fronts a period of stability followed with thermal, chemical, and biological (chlorophyll-a) stratification. Climatological data obtained during the cold front passage showed lower air temperature, higher wind speed and lower solar radiation. The response of this reservoir can exemplify a generalized process in all shallow reservoirs in the Southeast Brazil and could have several implications for management, particularly in relation to the phytoplankton population dynamics and development of cyanobacterial blooms. Using this as a basis, a predictive model will be developed with the aim of advancing management strategies specially for the drinking water reservoirs of the Metropolitan Region of São Paulo.

    The authors hypothesized that measurement of a specific product from reaction of N,N{prime}-dimethylthiourea (Me{sub 2}TU) and H{sub 2}O{sub 2} would provide a good indication of the H{sub 2}O{sub 2} scavenging and protection seen after addition of Me{sub 2}TU to biological systems. They found that addition of H{sub 2}O{sub 2} to Me{sub 2}TU yielded a single stable product, Me{sub 2}TU dioxide. Me{sub 2}TU dioxide formation correlated with Me{sub 2}TU consumption as a function of added H{sub 2}O{sub 2} concentration and was prevented by simultaneous addition of catalase (but not boiled catalase), superoxide dismutase, dimethyl sulfoxide, mannitol, or sodium benzoate. Me{sub 2}TU dioxide formation, Me{sub 2}TU consumption, and H{sub 2}O{sub 2} concentration increases occurred in mixtures containing phorbol 12-myristate 13-acetate (PMA) and normal human neutrophils but not in mixtures containing PMA and neutrophils from patients with chronic granulomatous disease or in mixtures containing PMA and normal neutrophils and catalase. Me{sub 2}TU dioxide formation also occurred in isolated rat lungs perfused with Me{sub 2}TU and H{sub 2}O{sub 2} but not in lungs perfused with Me{sub 2}TU and elastase, histamine, or oleic acid. In contrast, Me{sub 2}TU dioxide formation did not occur after exposure of Me{sub 2}TU to {sup 60}Co-generated hydroxyl radical or hypochlorous acid in the presence of catalase. The results indicate that reaction of Me{sub 2}TU with H{sub 2}O{sub 2} selectively forms Me{sub 2}TU may be useful for assessing the presence and significance of H{sub 2}O{sub 2} in biological systems.

    Mosquito-borne arboviruses are emerging world-wide as important human and animal pathogens. This makes assays for their accurate and rapid identification essential for public health, epidemiological, ecological studies. Over the past decade, many mono- and multiplexed assays targeting arboviruses nucleic acids have been reported. None has become established for the routine identification of multiple viruses in a "single tube" setting. With increasing multiplexing, the detection of viral RNAs is complicated by noise, false positives and negatives. In this study, an assay was developed that avoids these problems by combining two new kinds of nucleic acids emerging from the field of synthetic biology. The first is a "self-avoiding molecular recognition system" (SAMRS), which enables high levels of multiplexing. The second is an "artificially expanded genetic information system" (AEGIS), which enables clean PCR amplification in nested PCR formats. A conversion technology was used to place AEGIS component into amplicon, improving their efficiency of hybridization on Luminex beads. When Luminex "liquid microarrays" are exploited for downstream detection, this combination supports single-tube PCR amplification assays that can identify 22 mosquito-borne RNA viruses from the genera Flavivirus, Alphavirus, Orthobunyavirus. The assay differentiates between closely-related viruses, as dengue, West Nile, Japanese encephalitis, and the California serological group. The performance and the sensitivity of the assay were evaluated with dengue viruses and infected mosquitoes; as few as 6-10 dengue virions can be detected in a single mosquito.

  10. It's not just about innovation

    SciTech Connect

    Wiley, H. S.

    2008-03-01

    Last year, I was one of the reviewers of proposals to a newly created NIH program, the New Innovator Award. Its goal was to address a frequent criticism – that peer review is biased against innovation – and to fund exceptionally innovative, high impact research from new investigators. To encourage the submission of innovative ideas, preliminary data was not required. Nearly 2,200 applications were submitted, but only 30 awards were made, for a success rate of <1.4%. This suggests either that there are a lot of unfunded innovative ideas out there, or that the ability to submit a proposal without preliminary data was irresistible. Over the years, I have observed that very few innovative ideas are ever brought to the point where they have made a significant impact on biological research. Grant review panels implicitly understand this unpleasant truth. The defining characteristic of successful ideas are bright and preserving scientists who believe in their ideas and are willing to do whatever it takes to make them succeed. What Thomas Edison said about genius is equally applicable to innovation; it, too, is mostly about perspiration.

    This study sought to evaluate the in vitro biological response of human gingival fibroblasts (HGFs) co-coltured with Streptococcus mitis to bisphenol A glycidylmethacrylate/triethylene glycol dimethacrylate (BisGMA/TEGDMA) thermosets coated with Chitlac-nAg, a nanocomposite system with antimicrobial properties. To avoid bacterial adhesion to dental devices and to reduce cytotoxicity against eukaryotic cells, we coated BisGMA/TEGDMA methacrylic thermosets with a new material, Chitlac-nAg, formed by stabilizing silver nanoparticles, which have well-known antimicrobial properties, with a polyelectrolyte solution containing Chitlac. Cytotoxicity, cell morphology, cell migration and inflammatory interleukine-6 (IL-6) and prostaglandin E2 (PGE2) secretion were evaluated. Our results showed that the cytotoxicity exerted on HGFs by our nanocomposite material was absent in our co-culture model, where fibroblasts are able to adhere and migrate. After 24 h thermosets coated with Chitlac as well as those coated with Chitlac-nAg exerted a minimal cytotoxic effect on HGFs, while after 48 h LDH release rises up 20%. Moreover the presence of S. mitis reduced this release in a greater amount with Chitlac-nAg coated thermosets. The secretion of IL-6 was significant in both Chitlac and Chitlac-nAg coated thermosets, but PGE2 production was minimal, suggesting that the IL-6 production was not related to an inflammatory response. Co-culture and the addiction of saliva did not influence IL-6 and PGE2 secretion. Data obtained in the present work suggest that Chitlac n-Ag coated thermosets could significantly improve the success rates of restorative dentistry, since they limit bacterial adhesion and are not toxic to HGFs.

  16. Weather-based prediction of Plasmodium falciparum malaria in epidemic-prone regions of Ethiopia I. Patterns of lagged weather effects reflect biological mechanisms

    2004-01-01

    Background Malaria epidemics due to Plasmodium falciparum are reported frequently in the East African highlands with high case fatality rates. There have been formal attempts to predict epidemics by the use of climatic variables that are predictors of transmission potential. However, little consensus has emerged about the relative importance and predictive value of different factors. Understanding the reasons for variation is crucial to determining specific and important indicators for epidemic prediction. The impact of temperature on the duration of a mosquito's life cycle and the sporogonic phase of the parasite could explain the inconsistent findings. Methods Daily average number of cases was modeled using a robust Poisson regression with rainfall, minimum temperature and maximum temperatures as explanatory variables in a polynomial distributed lag model in 10 districts of Ethiopia. To improve reliability and generalizability within similar climatic conditions, we grouped the districts into two climatic zones, hot and cold. Results In cold districts, rainfall was associated with a delayed increase in malaria cases, while the association in the hot districts occurred at relatively shorter lags. In cold districts, minimum temperature was associated with malaria cases with a delayed effect. In hot districts, the effect of minimum temperature was non-significant at most lags, and much of its contribution was relatively immediate. Conclusions The interaction between climatic factors and their biological influence on mosquito and parasite life cycle is a key factor in the association between weather and malaria. These factors should be considered in the development of malaria early warning system. PMID:15541174

  17. Delivery Innovations.

    PubMed

    2017-03-01

    The need for innovations in care delivery is recognized by providers, payers, and patients alike. Hospitals, physicians, and other clinicians are experimenting with new models of care designed to better meet patients' needs, reduce administrative burdens, and lower costs. The Affordable Care Act placed the Medicare and Medicaid programs at the center of a national effort to experiment with delivery and payment models designed to improve care and contain costs. These public-sector efforts have often aligned with private initiatives, such as the use of reference pricing-in which an insurer will only pay for a service at the price available from the lowest-cost provider. Employers in the public and private sectors have adopted value-based insurance design, in which copayments and deductibles are calibrated to the clinical benefit obtained from different services. Patients have the most to gain-or lose-from delivery innovations. Better, more efficient care should translate into better health and lower costs, but payment models designed to encourage innovation may have the unintended effect of limiting access to care.

    To assess systematically the possible differences in pathology between pT1a and pT1b renal cell carcinomas (RCCs), as the sixth edition of the Tumour-Nodes-Metastasis (TNM) system implemented a subdivision of category pT1 into pT1a (<4 cm) and pT1b (4-7 cm), based on clinical outcome analysis and the approach to therapy. Conventional histopathology and immunohistochemical expression of several biomarkers were analysed in 66 patients with pT1a and 29 with pT1b RCCs, using a tissue microarray technique. After 2 years of follow-up, none of the 66 patients with pT1a and three of the 29 with pT1b tumours developed progressive disease. The tumour was grade 3 in four (6%) pT1a and 11 (38%) pT1b RCCs. Immunohistochemically, pT1a RCCs were characterized by strong expression of p27 (79%), bcl-2 (67%), MUC1 (87%), insulin-like growth factor (IGF)-I (71%) and CD10 (88%), as well as moderate expression of IGF-I receptor (43%) and low expression of epidermal growth factor receptor (EGFR, 20%). During progression to category pT1b, expression of p27 significantly decreased (54%) and EGFR expression increased (38%). Moreover, membranous staining patterns of MUC1 and CD10 changed from apical to circumferential in clear cell RCCs. p53 (pT1a 23%, pT1b 28%), E-cadherin (10% and 17%), MIB-1 (1.2% and 1.5%) and Skp2 (2% and none) expression seemed to be of minor importance. This is the first study to show that the subdivision of category pT1 implemented in the latest issue of the TNM system is reflected by differences in conventional histopathology and expression of biomarkers.

    The specular neutron reflectivity is a technique enabling the measurement of neutron scattering length density profile perpendicular to the plane of a surface or an interface, and thereby the profile of chemical composition. The characteristic sizes that are probed range from around 5 Å up 5000 Å. It is a scattering technique that averages information on the entire surface and it is therefore not possible to obtain information within the plane of the interface. The specific properties of neutrons (possibility of tuning the contrast by isotopic substitution, sensitivity to magnetism, negligible absorption, low energy of the incident neutrons) makes it particularly interesting in the fields of soft matter, biophysics and magnetic thin films. This course is a basic introduction to the technique and does not address the magnetic reflectivity. It is composed of three parts describing respectively its principle and its formalism, the experimental aspects of the method (spectrometers, samples) and two examples related to the materials for energy.

    Humanity has just crossed a major landmark in its history with the majority of people now living in cities. Cities have long been known to be society's predominant engine of innovation and wealth creation, yet they are also its main source of crime, pollution, and disease. The inexorable trend toward urbanization worldwide presents an urgent challenge for developing a predictive, quantitative theory of urban organization and sustainable development. Here we present empirical evidence indicating that the processes relating urbanization to economic development and knowledge creation are very general, being shared by all cities belonging to the same urban system and sustained across different nations and times. Many diverse properties of cities from patent production and personal income to electrical cable length are shown to be power law functions of population size with scaling exponents, β, that fall into distinct universality classes. Quantities reflecting wealth creation and innovation have β ≈1.2 >1 (increasing returns), whereas those accounting for infrastructure display β ≈0.8 <1 (economies of scale). We predict that the pace of social life in the city increases with population size, in quantitative agreement with data, and we discuss how cities are similar to, and differ from, biological organisms, for which β<1. Finally, we explore possible consequences of these scaling relations by deriving growth equations, which quantify the dramatic difference between growth fueled by innovation versus that driven by economies of scale. This difference suggests that, as population grows, major innovation cycles must be generated at a continually accelerating rate to sustain growth and avoid stagnation or collapse. PMID:17438298

    2016-06-01

    Objective This paper aims to demonstrate that any suggestion that there is a need for specific innovation laws is flawed. Innovation is central to good medical practice and is adequately supported by current law. Methods The paper reviews the nature of medical innovation and outlines recent attempts in the UK to introduce specific laws aimed at 'encouraging' and 'supporting' innovation. The current legal framework is outlined and the role of the law in relation to medical innovation explored. Results The analysis demonstrates the cyclic relationship between medical advancement and the law and concludes that there is no requirement for specific innovation laws. Conclusions The law not only supports innovation and development in medical treatment but encourages it as central to a functioning medical system. There is no need to introduce specific laws aimed at medical innovation; to do so represents an unnecessary legal innovation and serves to complicate matters. What is known about the topic? Over recent months, there has been a great deal of discussion surrounding the law in the context of medical innovation. This was driven by the attempts in the UK to introduce specific laws in the Medical Innovation Bill. The general subject matter - negligence and the expected standard of care in the provision of treatment - is very well understood, but not in cases where the treatment can be described as innovative. The general rhetoric in both the UK and Australia around the Medical Innovation Bill demonstrates a lack of understanding of the position of the law with regards to innovative treatment. What does this paper add? This paper adds clarity to the debate. It presents the law and explains the manner in which the law can operate around innovative treatment. The paper asserts that medical innovation is both supported and encouraged by existing legal principles. What are the implications for practitioners? The paper presents an argument that can guide the policy position

    2006-01-01

    Objective: To describe the field of surgical innovation from a historical perspective, applying new findings from research in technology innovation. Background: While surgical innovation has a rich tradition, as a field of study it is embryonic. Only a handful of academic centers of surgical innovation exist, all of which have arisen within the last 5 years. To this point, the field has not been well defined, nor have future options to promote surgical innovation been thoroughly explored. It is clear that surgical innovation is fundamental to surgical progress and has significant health policy implications. A process of systematically evaluating and promoting innovation in surgery may be critical in the evolving practice of medicine. Methods: A review of the academic literature in technology innovation was undertaken. Articles and books were identified through technical, medical, and business sources. Luminaries in surgical innovation were interviewed to develop further relevance to surgical history. The concepts in technology innovation were then applied to innovation in surgery, using the historical example of surgical endoscopy as a representative area, which encompasses millennia of learning and spans multiple specialties of care. Results: The history of surgery is comprised largely of individual, widely respected surgeon innovators. While respecting individual accomplishments, surgeons as a group have at times hindered critical innovation to the detriment of our profession and patients. As a clinical discipline, surgery relies on a tradition of research and attracting the brightest young minds. Innovation in surgery to date has been impressive, but inconsistently supported. Conclusion: A body of knowledge on technology innovation has been developed over the last decade but has largely not been applied to surgery. New surgical innovation centers are working to define the field and identify critical aspects of surgical innovation promotion. It is our

    Truly impactful innovation can only be recognized in retrospect. Moreover, almost by definition, developing algorithmic paths on roadmaps for innovation are likely to be unsuccessful because innovators do not generally follow established routes. Nonetheless, environments can be established within Departments of Pediatrics that promote innovating thinking. The environmental factors necessary to do so include: (1) demand that academic Pediatrics Departments function in an aggressively scholarly mode; (2) capture the most fundamental science in postnatal developmental biology; (3) focus education and training on the boundaries of our knowledge, rather than the almost exclusive attention to what we think we already know; (4) devote mentoring, time and resources to only the most compelling unanswered questions in the pediatric sciences, including nutrition; (5) accept only systematic, evidence-based answers to clinical questions; (6) if systematic, evidence-based data are not available, design the proper studies to get them; (7) prize questioning the answers to further move beyond the knowledge limit; (8) support the principle that experiments in children will be required to convincingly answer clinical questions important to children, and (9) establish the multicenter resources in pediatric scientist training, clinical study design and implementation, and laboratory and instrument technologies required to answer today's questions with tomorrow's methods.

    The nebula Messier 78 takes centre stage in this image taken with the Wide Field Imager on the MPG/ESO 2.2-metre telescope at the La Silla Observatory in Chile, while the stars powering the bright display take a backseat. The brilliant starlight ricochets off dust particles in the nebula, illuminating it with scattered blue light. Igor Chekalin was the overall winner of ESO's Hidden Treasures 2010 astrophotography competition with his image of this stunning object. Messier 78 is a fine example of a reflection nebula. The ultraviolet radiation from the stars that illuminate it is not intense enough to ionise the gas to make it glow - its dust particles simply reflect the starlight that falls on them. Despite this, Messier 78 can easily be observed with a small telescope, being one of the brightest reflection nebulae in the sky. It lies about 1350 light-years away in the constellation of Orion (The Hunter) and can be found northeast of the easternmost star of Orion's belt. This new image of Messier 78 from the MPG/ESO 2.2-metre telescope at the La Silla Observatory is based on data selected by Igor Chekalin in his winning entry to the Hidden Treasures competition [1]. The pale blue tint seen in the nebula in this picture is an accurate representation of its dominant colour. Blue hues are commonly seen in reflection nebulae because of the way the starlight is scattered by the tiny dust particles that they contain: the shorter wavelength of blue light is scattered more efficiently than the longer wavelength red light. This image contains many other striking features apart from the glowing nebula. A thick band of obscuring dust stretches across the image from the upper left to the lower right, blocking the light from background stars. In the bottom right corner, many curious pink structures are also visible, which are created by jets of material being ejected from stars that have recently formed and are still buried deep in dust clouds.

    Synthetic biology is an interdisciplinary field that takes top-down approaches to understand and engineer biological systems through design-build-test cycles. A number of advances in this relatively young field have greatly accelerated such engineering cycles. Specifically, various innovative tools were developed for in silico biosystems design, DNA de novo synthesis and assembly, construct verification, as well as metabolite analysis, which have laid a solid foundation for building biological foundries for rapid prototyping of improved or novel biosystems. This review summarizes the state-of-the-art technologies for synthetic biology and discusses the challenges to establish such biological foundries.

    The promotion of reflective capacity within the teaching of clinical skills and professionalism is posited as fostering the development of competent health practitioners. An innovative approach combines structured reflective writing by medical students and individualized faculty feedback to those students to augment instruction on reflective practice. A course for preclinical students at the Warren Alpert Medical School of Brown University, entitled "Doctoring," combined reflective writing assignments (field notes) with instruction in clinical skills and professionalism and early clinical exposure in a small-group format. Students generated multiple e-mail field notes in response to structured questions on course topics. Individualized feedback from a physician-behavioral scientist dyad supported the students' reflective process by fostering critical-thinking skills, highlighting appreciation of the affective domain, and providing concrete recommendations. The development and implementation of this innovation are presented, as is an analysis of the written evaluative comments of students taking the Doctoring course. Theoretical and clinical rationales for features of the innovation and supporting evidence of their effectiveness are presented. Qualitative analyses of students' evaluations yielded four themes of beneficial contributions to their learning experience: promoting deeper and more purposeful reflection, the value of (interdisciplinary) feedback, the enhancement of group process, and personal and professional development. Evaluation of the innovation was the fifth theme; some limitations are described, and suggestions for improvement are provided. Issues of the quality of the educational paradigm, generalizability, and sustainability are addressed.

    OSF HealthCare, based in Peoria, Illinois, has developed an innovative strategy to adapt to the changes and forces disrupting the healthcare environment. This strategy evolved organically from the performance improvement efforts we began more than 15 years ago, as well as from the lessons we learned from years of research into the innovative practices and platforms of other healthcare institutions and of companies in other industries. More important, the strategy reflects our mission "to serve persons with the greatest care and love."The OSF innovation model has three components: internal innovations, partnering with external entities, and validating innovations through simulation. OSF has an ongoing and comprehensive commitment to innovation. Examples include our initiative to transform our model of care in primary care clinics by expanding access, reducing costs, and increasing efficiency; our partnerships with outside entities to find revolutionary solutions and products in which we can invest; and our establishment of a world-class simulation and education center.OSF HealthCare could not do any of this if it lacked the support of its people. To that end, we continue to work on embedding a culture of innovation across all of our facilities. Ours is a culture in which everyone is encouraged to voice creative ideas and no one is afraid to fail-all for the betterment of our organization and the patients we serve.

  3. The Teaching of Biochemistry: An Innovative Course Sequence Based on the Logic of Chemistry

    1998-06-01

    An innovative course sequence for the teaching of biochemistry is offered, which more truly reflects the common philosophy found in biochemistry texts: that the foundation of biological phenomena can best be understood through the logic of chemistry. Topic order is chosen to develop an emerging understanding that is based on chemical principles. Preeminent biological questions serve as a framework for the course. Lipid and lipid-aggregate structures are introduced first, since it is more logical to discuss the intermolecular association of simple amphiphiles to form micelle and bilayer formations than to discuss the complexities of protein structure/folding. Protein, nucleic acid, and carbohydrate structures are studied next. Binding, a noncovalent process and the simplest expression of macromolecular function, follows. The physical (noncovalent) transport of solute molecules across a biological membrane is studied next, followed by the chemical transformation of substrates by enzymes. These are logical extensions of the expression of molecular function, first involving a simpler (physical transport) and second, a more complex (covalent transformation) process. The final sequence involves energy and signal transduction. This unique course sequence emerges naturally when chemical logic is used as an organizing paradigm for structuring a biochemistry course. Traditional order, which seems to reflect historic trends in research, or even an order derived from the central dogma of biology can not provide this logical framework.

    This review focuses on parallels between the selectionist sciences of evolutionary biology and behavior analysis. In selectionism, complex phenomena are interpreted as the cumulative products of relatively simple processes acting over time—natural selection in evolutionary biology and reinforcement in behavior analysis. Because evolutionary biology is the more mature science, an examination of the factors that led to the triumph of natural selection provides clues whereby reinforcement may achieve a similar fate in the science of behavior.

    Gladyshev, Georgi P.

    The author sets forth general considerations pertaining to the thermodynamic theory of biological evolution and the aging of living organisms. It becomes much easier to comprehend the phenomenon of life scrutinizing the formation of structural hierarchies of biological matter applying different temporal scales. These scales are 'identified' by nature itself, and this is reflected in the law of temporal hierarchies. The author discusses some misunderstandings in thermodynamics and evolutionary biology. A simple physicochemical model of biological evolution and the development of living beings is proposed. The considered theory makes it possible to use physicochemical evaluations to develop effective anti-aging diets.

    The purpose of the present study was to describe the innovativeness and the rate of adoption of change among chief nursing officers (CNOs) of acute care hospitals, and explore the difference in the innovativeness of CNOs of Magnet hospitals vs. non-Magnet hospitals. There is little evidence to guide the description of innovativeness for nurse leaders, crucial to the implementation of evidence-based practice standards. CNOs of acute care hospitals of New York State participated in a mailed survey which incorporated the Scale for the Measurement of Innovativeness. The response rate was 41% (106/261). The majority of the sample was prepared at the master's level with 5-10 years of experience in the CNO role. A significant relationship was found between the innovativeness scale scores and the innovativeness diversity index. The CNOs who completed more leadership courses had implemented significantly more types of innovations and had higher innovativeness scale scores.   Graduate level education, years of CNO experience and leadership course completion were identified as significantly influencing innovativeness of CNOs. The characteristics of innovativeness for nurse leaders presented in the present study may assist organizations, CNOs and the Magnet recognition programme to describe innovativeness that supports organizations to continuously improve the quality of patient care. © 2011 The Authors.

  17. Can We Assess Efficiency and Innovation in Transfer?

    NASA Astrophysics Data System (ADS)

    Rebello, N. Sanjay

    2009-11-01

    Schwartz, Bransford and Sears [1] propose a two-dimensional framework that describes transfer in terms of efficiency and innovation. Efficiency is the ability to apply prior knowledge to new situations quickly and accurately. Innovation is the ability to question assumptions, let go of prior knowledge and generate new ideas. Schwartz et al. argue that most educational assessments focus on efficiency at the expense of innovation. We suggest that this perspective does not adequately reflect the challenges that our students face while problem solving. For instance, while faculty may find end-of-chapter physics problems to be routine and overly focused on efficiency, our students, who lack prior knowledge and experience may find these problems to be novel and innovative. We propose a framework based on an operational meaning of `efficiency' and `innovation' and development of criteria to measure these constructs in ways that reflect both learners' challenges as well as educators' expectations.

  18. Designing synthetic biology.

    PubMed

    Agapakis, Christina M

    2014-03-21

    Synthetic biology is frequently defined as the application of engineering design principles to biology. Such principles are intended to streamline the practice of biological engineering, to shorten the time required to design, build, and test synthetic gene networks. This streamlining of iterative design cycles can facilitate the future construction of biological systems for a range of applications in the production of fuels, foods, materials, and medicines. The promise of these potential applications as well as the emphasis on design has prompted critical reflection on synthetic biology from design theorists and practicing designers from many fields, who can bring valuable perspectives to the discipline. While interdisciplinary connections between biologists and engineers have built synthetic biology via the science and the technology of biology, interdisciplinary collaboration with artists, designers, and social theorists can provide insight on the connections between technology and society. Such collaborations can open up new avenues and new principles for research and design, as well as shed new light on the challenging context-dependence-both biological and social-that face living technologies at many scales. This review is inspired by the session titled "Design and Synthetic Biology: Connecting People and Technology" at Synthetic Biology 6.0 and covers a range of literature on design practice in synthetic biology and beyond. Critical engagement with how design is used to shape the discipline opens up new possibilities for how we might design the future of synthetic biology.

  20. The Beneficial Role of Mobility for the Emergence of Innovation.

    PubMed

    Armano, Giuliano; Javarone, Marco Alberto

    2017-05-11

    Innovation is a key ingredient for the evolution of several systems, including social and biological ones. Focused investigations and lateral thinking may lead to innovation, as well as serendipity and other random discovery processes. Some individuals are talented at proposing innovation (say innovators), while others at deeply exploring proposed novelties, at getting further insights on a theory, or at developing products, services, and so on (say developers). This separation in terms of innovators and developers raises an issue of paramount importance: under which conditions a system is able to maintain innovators? According to a simple model, this work investigates the evolutionary dynamics that characterize the emergence of innovation. In particular, we consider a population of innovators and developers, in which agents form small groups whose composition is crucial for their payoff. The latter depends on the heterogeneity of the formed groups, on the amount of innovators they include, and on an award-factor that represents the policy of the system for promoting innovation. Under the hypothesis that a "mobility" effect may support the emergence of innovation, we compare the equilibria reached by our population in different cases. Results confirm the beneficial role of "mobility", and the emergence of further interesting phenomena.

  4. The discipline of innovation.

    PubMed

    Drucker, P F

    1998-01-01

    Some innovations spring from a flash of genius. But as Peter Drucker points out in this HBR Classic, most result from a conscious, purposeful search for opportunities. For managers seeking innovation, engaging in disciplined work is more important than having an entrepreneurial personality. Writing originally in the May-June 1985 issue, Drucker describes the major sources of opportunities for innovation. Within a company or industry, opportunities can be found in unexpected occurrences, incongruities of various kinds, process needs, or changes in an industry or market. Outside a company, opportunities arise from demographic changes, changes in perception, or new knowledge. These seven sources overlap, and the potential for innovation may well lie in more than one area at a time. Innovations based on new knowledge, of course, tend to have the greatest effect on the marketplace. But it often takes decades before the ideas are translated into actual products, processes, or services. The other sources of innovation are easier and simpler to handle, yet they still require managers to look beyond established practices. Drucker emphasizes that in seeking opportunities, innovators need to look for simple, focused solutions to real problems. The greatest praise an innovation can receive is for people to say, "This is obvious!" Grandiose ideas designed to revolutionize an industry rarely work. Innovation, like any other endeavor, takes talent, ingenuity, and knowledge. But Drucker cautions that if diligence, persistence, and commitment are lacking, companies are unlikely to succeed at the business of innovation.

    Here, I argue that computational thinking and techniques are so central to the quest of understanding life that today all biology is computational biology. Computational biology brings order into our understanding of life, it makes biological concepts rigorous and testable, and it provides a reference map that holds together individual insights. The next modern synthesis in biology will be driven by mathematical, statistical, and computational methods being absorbed into mainstream biological training, turning biology into a quantitative science.

    Malaria eradication is a global health priority, but current therapies are not always suitable for providing a radical cure. Artemisinin has paved the way for the current malaria treatment, the so-called Artemisinin-based Combination Therapy (ACT). However, with the detection of resistance to ACT, innovative compounds active against multiple parasite species and at multiple life stages are needed. GlaxoSmithKline has recently disclosed the results of a phenotypic screening of an internal library, publishing a collection of 400 antimalarial chemotypes, termed the "Malaria Box". After analysis of the data set, we have carried out a medicinal chemistry campaign in order to define the structure-activity relationships for one of the released compounds, which embodies a benzothiophene-2-carboxamide core. Thirty-five compounds were prepared, and a description of the structural features responsible for the in vitro activity against different strains of P. falciparum, the toxicity, and the metabolic stability is herein reported.

  15. Drosophila Sex Combs as a Model of Evolutionary Innovations

    PubMed Central

    Kopp, Artyom

    2011-01-01

    The diversity of animal and plant forms is shaped by nested evolutionary innovations. Understanding the genetic and molecular changes responsible for these innovations is therefore one of the key goals of evolutionary biology. From the genetic point of view, the origin of novel traits implies the origin of new regulatory pathways to control their development. To understand how these new pathways are assembled in the course of evolution, we need model systems that combine relatively recent innovations with a powerful set of genetic and molecular tools. One such model is provided by the Drosophila sex comb – a male-specific morphological structure that evolved in a relatively small lineage related to the model species D. melanogaster. Our extensive knowledge of sex comb development in D. melanogaster provides the basis for investigating the genetic changes responsible for sex comb origin and diversification. At the same time, sex combs can change on microevolutionary timescales and differ spectacularly among closely related species, providing opportunities for direct genetic analysis and for integrating developmental and population-genetic approaches. Sex comb evolution is associated with the origin of novel interactions between HOX and sex determination genes. Activity of the sex determination pathway was brought under the control of the HOX code to become segment-specific, while HOX gene expression became sexually dimorphic. At the same time, both HOX and sex determination genes were integrated into the intrasegmental spatial patterning network, and acquired new joint downstream targets. Phylogenetic analysis shows that similar sex comb morphologies evolved independently in different lineages. Convergent evolution at the phenotypic level reflects convergent changes in the expression of HOX and sex determination genes, involving both independent gains and losses of regulatory interactions. However, the downstream cell differentiation programs have diverged between

    In the complex sport of American football, teams rely on playbooks as thick as the Manhattan phone directory. But when it comes to creating innovative growth businesses-which is at least as complicated as professional football--most companies have not developed detailed game plans. Indeed, many managers have concluded that a fog enshrouds the world of innovation, obscuring high-potential opportunities. The authors believe that companies can penetrate that fog by developing growth strategies based on disruptive innovations, as defined by Clayton Christensen. Such innovations conform to a pattern: They offer an entirely new solution; they perform adequately along traditional dimensions and much better along other dimensions that matter more to target customers; and they are not initially appealing to powerful incumbents. Companies can develop customized checklists, or playbooks, by combining this basic pattern with analysis of major innovations in their markets. The key early on is to focus not on detailed financial estimates--which will always guide companies toward the markets most hostile to disruptive innovations--but on how well the innovation fits the pattern of success. It's also crucial to encourage flexibility: Companies must be willing to kill projects that are going nowhere, exempt innovations from standard development processes, and avoid burdening project teams with extra financing, which can keep them heading in the wrong direction. Companies can create competitive advantage by becoming champions at defining the pattern of successful innovations and executing against it. But as that pattern becomes obvious--and others emerge-building a sustainable advantage on innovation competencies will again prove elusive.

  17. The innovation value chain.

    2007-06-01

    The challenges of coming up with fresh ideas and realizing profits from them are different for every company. One firm may excel at finding good ideas but may have weak systems for bringing them to market. Another organization may have a terrific process for funding and rolling out new products and services but a shortage of concepts to develop. In this article, Hansen and Birkinshaw caution executives against using the latest and greatest innovation approaches and tools without understanding the unique deficiencies in their companies' innovation systems. They offer a framework for evaluating innovation performance: the innovation value chain. It comprises the three main phases of innovation (idea generation, conversion, and diffusion) as well as the critical activities performed during those phases (looking for ideas inside your unit; looking for them in other units; looking for them externally; selecting ideas; funding them; and promoting and spreading ideas companywide). Using this framework, managers get an end-to-end view of their innovation efforts. They can pinpoint their weakest links and tailor innovation best practices appropriately to strengthen those links. Companies typically succumb to one of three broad "weakest-link" scenarios. They are idea poor, conversion poor, or diffusion poor. The article looks at the ways smart companies - including Intuit, P&G, Sara Lee, Shell, and Siemens- modify the best innovation practices and apply them to address those organizations' individual needs and flaws. The authors warn that adopting the chain-based view of innovation requires new measures of what can be delivered by each link in the chain. The approach also entails new roles for employees "external scouts" and "internal evangelists," for example. Indeed, in their search for new hires, companies should seek out those candidates who can help address particular weaknesses in the innovation value chain.

    How to promote the innovative activities is an important problem for modern society. In this paper, combining the evolutionary games with information spreading, we propose a lattice model to investigate dynamics of human innovative behaviors based on benefit-driven assumption. Simulations show several properties in agreement with peoples’ daily cognition on innovative behaviors, such as slow diffusion of innovative behaviors, gathering of innovative strategy on “innovative centers”, and quasi-localized dynamics. Furthermore, our model also emerges rich non-Poisson properties in the temporal-spatial patterns of the innovative status, including the scaling law in the interval time of innovation releases and the bimodal distributions on the spreading range of innovations, which would be universal in human innovative behaviors. Our model provides a basic framework on the study of the issues relevant to the evolution of human innovative behaviors and the promotion measurement of innovative activities.

    Growing interest in the promise of patient-centered care has led to numerous health care innovations, including the patient-centered medical home, shared decision-making, and payment reforms. How best to vet and adopt innovations is an open question. Washington State has been a leader in health care reform and is a rich laboratory for patient-centered innovations. We sought to understand the process of patient-centered care innovation undertaken by innovative health care organizations - from strategic planning to goal selection to implementation to maintenance. We conducted key-informant interviews with executives at five health plans, five provider organizations, and ten primary care clinics in Washington State. At least two readers of each interview transcript identified themes inductively; final themes were determined by consensus. Innovation in patient-centered care was a strategic objective chosen by nearly every organization in this study. However, other goals were paramount: cost containment, quality improvement, and organization survival. Organizations commonly perceived effective chronic disease management and integrated health information technology as key elements for successful patient-centered care innovation. Inertia, resource deficits, fee-for-service payment, and regulatory limits on scope of practice were cited as barriers to innovation, while organization leadership, human capital, and adaptive culture facilitated innovation. Patient-centered care innovations reflected organizational perspectives: health plans emphasized cost-effectiveness while providers emphasized health care delivery processes. Health plans and providers shared many objectives, yet the two rarely collaborated to achieve them. The process of innovation is heavily dependent on organizational culture and leadership. Policymakers can improve the pace and quality of patient-centered innovation by setting targets and addressing conditions for innovation.

    Abstract The Department of Health and the Wellcome Trust, in co-operation with NHS England, asked RAND Europe to conduct a limited consultation with key stakeholders about the practicality of measures and incentives proposed as part of the NHS Accelerated Access Review (AAR), which aims to assess the pathways for the development, assessment, and adoption of innovative medicines and medical technology. Through a focused engagement exercise with key healthcare stakeholders this project explored the implications of selected interim AAR propositions and feasibility of implementation for key actors, in primary and secondary care as well as commissioners and academia. Specifically, the project investigated the feasibility of implementation of three specific propositions including: a new earmarked fund to encourage AHSNs and other key innovation actors to re-design systems to embrace innovation; mobilising the influence of clinical system leaders to champion change; and encouraging secondary care organisations to take on “innovation champion” roles linked to financial incentives and a new emphasis on accountable care organisations. Data was collected on the feasibility of the three AAR propositions from a workshop with AHSN CEOs and Commercial Directors and interviews with senior NHS staff in three AHSN regions (South West, University College London Partners, and North East, North Cumbria). The study concludes with reflections on the feasibility of each recommendation and identifies factors expected to facilitate or challenge their implementation, as well as considering the wider cross cutting issues that may influence the adoption and diffusion of innovation in the NHS.

    No matter how hard companies try, their approaches to innovation often don't grow the top line in the sustained, profitable way investors expect. For many companies, there's a huge difference between what's in their business plans and the market's expectations for growth (as reflected in firms' share prices, market capitalizations, and P/E ratios). This growth gap springs from the fact that companies are pouring money into their insular R&D labs instead of working to understand what the customer wants and using that understanding to drive innovation. As a result, even companies that spend the most on R&D remain starved for both customer innovation and market-capitalization growth. In this article, the authors spell out a systematic approach to innovation that continuously fuels sustained, profitable growth. They call this approach customer-centric innovation, or CCI. At the heart of CCI is a rigorous customer R&D process that helps companies to continually improve their understanding of who their customers are and what they need. By so doing, they consistently create or improve their customer value proposition. Customer R&D also focuses on better ways of communicating value propositions and delivering the complete experience to real customers. Since so much of the learning about customers and so much of the experimentation with different segmentations, value propositions, and delivery mechanisms involve the people who regularly deal with customers, it is absolutely essential for frontline employees to be at the center of the CCI process. Simply put, customer R&D propels the innovation effort away from headquarters and the traditional R&D lab out to those closest to the customer. Using the example of the luggage manufacturer Tumi, the authors provide a step-by-step approach for achieving true customer-centric innovation.

    Biogas or biomethane is traditionally produced via anaerobic digestion, or recently by thermochemical or a combination of thermochemical and biological processes via syngas (CO and H2) fermentation. However, many of the feedstocks have recalcitrant structure and are difficult to digest (e.g., lignocelluloses or keratins), or they have toxic compounds (such as fruit flavors or high ammonia content), or not digestible at all (e.g., plastics). To overcome these challenges, innovative strategies for enhanced and economically favorable biogas production were proposed in this review. The strategies considered are commonly known physical pretreatment, rapid decompression, autohydrolysis, acid- or alkali pretreatments, solvents (e.g. for lignin or cellulose) pretreatments or leaching, supercritical, oxidative or biological pretreatments, as well as combined gasification and fermentation, integrated biogas production and pretreatment, innovative biogas digester design, co-digestion, and bio-augmentation.

    How mechanical and biological processes are coordinated across cells, tissues, and organs to produce complex traits is a key question in biology. Cardamine hirsuta, a relative of Arabidopsis thaliana, uses an explosive mechanism to disperse its seeds. We show that this trait evolved through morphomechanical innovations at different spatial scales. At the organ scale, tension within the fruit wall generates the elastic energy required for explosion. This tension is produced by differential contraction of fruit wall tissues through an active mechanism involving turgor pressure, cell geometry, and wall properties of the epidermis. Explosive release of this tension is controlled at the cellular scale by asymmetric lignin deposition within endocarp b cells-a striking pattern that is strictly associated with explosive pod shatter across the Brassicaceae plant family. By bridging these different scales, we present an integrated mechanism for explosive seed dispersal that links evolutionary novelty with complex trait innovation. VIDEO ABSTRACT.

    Moving an idea from a concept to the marketplace is difficult. Innovators can overcome the obstacles with the help of US DOE`s Inventions and innovation program (IIP). IIP is one of several programs supported by DOE`s Office of Energy Efficiency and Renewable Energy, which has the goal of developing cost-effective renewable energy and energy-efficiency technologies. The Innovative Concepts Program (InnCon) provides valuable assistance at the beginning when innovators are just starting to explore their concepts. It provides seed money to allow innovators to determine if their ideas are technically and economically feasible. InnCon operates in cycles of roughly 1-2 years; for each cycle it chooses an energy-related topic and invites innovators to submit proposals for funding, and up to 15 innovators per cycle are awarded seed money. InnCon is intended to fund novel ideas that are significant departures from existing technologies. Well-developed inventions past the conceptual stage can apply to Energy-Related Inventions Program (ERIP), which is also part of IIP. This brochure describes the InnCon program and how it is advertised and administered, and gives a contact name and address.

    Diffuse reflectance spectroscopy with a fiber optic probe is a powerful tool for quantitative tissue characterization and disease diagnosis. Significant systematic errors can arise in the measured reflectance spectra and thus in the derived tissue physiological and morphological parameters due to real-time instrument fluctuations. We demonstrate a novel fiber optic probe with real-time, self-calibration capability that can be used for UV-visible diffuse reflectance spectroscopy in biological tissue in clinical settings. The probe is tested in a number of synthetic liquid phantoms over a wide range of tissue optical properties for significant variations in source intensity fluctuations caused by instrument warm up and day-to-day drift. While the accuracy for extraction of absorber concentrations is comparable to that achieved with the traditional calibration (with a reflectance standard), the accuracy for extraction of reduced scattering coefficients is significantly improved with the self-calibration probe compared to traditional calibration. This technology could be used to achieve instrument-independent diffuse reflectance spectroscopy in vivo and obviate the need for instrument warm up and post∕premeasurement calibration, thus saving up to an hour of precious clinical time.

    The public health threat of antibiotic resistance has gained attention at the highest political levels globally, and recommendations on how to respond are being considered for implementation. Among the recommended responses being explored for their feasibility is the introduction of economic incentives to promote research and development of new antibiotics. There is broad agreement that public investment should stimulate innovation and be linked to policies promoting sustainable and equitable access to antibiotics. Though commonly used, the term 'innovation' is not based on a common understanding. This article aims to initiate discussion on the meaning of 'innovation' in this context. Literature and expert opinion. As the definition of a novel class (novel scaffold, novel pharmacophore), a novel target (novel binding site) and a novel mode of action-the three traditional criteria for 'innovation' in this context-may be confounded by the complexities of antibacterial drug discovery, a biological and outcome-oriented definition of innovation is presented to initiate discussion. Such an expanded definition of innovation in this specific context is based on the overarching requirement that a drug not be affected by cross-resistance to existing drugs in the organisms and indications for which it is intended to be used, and that it have low potential for high-frequency, high-level single-step resistance if intended as a single drug therapy. Policy makers, public health authorities and funders could use such a comprehensive definition of innovation to prioritize where publicly funded incentives should be applied.

  18. Biology Teachers Designing Context-Based Lessons for Their Classroom Practice—The importance of rules-of-thumb

    In science education in the Netherlands new, context-based, curricula are being developed. As in any innovation, the outcome will largely depend on the teachers who design and implement lessons. Central to the study presented here is the idea that teachers, when designing lessons, use rules-of-thumb: notions of what a lesson should look like if certain classroom outcomes are to be reached. Our study aimed at (1) identifying the rules-of-thumb biology teachers use when designing context-based lessons for their own classroom practice, and (2) assessing how these personal rules-of-thumb relate to formal innovative goals and lesson characteristics. Six biology teachers with varying backgrounds designed and implemented a lesson or series of lessons for their own practice, while thinking aloud. We interviewed the teachers and observed their lessons. Our results suggest that rules-of-thumb, which differed substantially among the teachers, indeed to a great extent guide the decisions teachers make when designing (innovative) lessons. These rules-of-thumb were often strongly associated with intended lesson outcomes. Also, teachers' personal rules-of-thumb were more powerful in determining the lesson design than formal innovative goals and lesson characteristics. The results of this study encourage more research into how rules-of-thumb reflect teachers' practical knowledge, for which suggestions are made.

    The field of synthetic biology has made rapid progress in a number of areas including method development, novel applications and community building. In seeking to make biology “engineerable,” synthetic biology is increasing the accessibility of biological research to researchers of all experience levels and backgrounds. One of the underlying strengths of synthetic biology is that it may establish the framework for a rigorous bottom-up approach to studying biology starting at the DNA level. Building upon the existing framework established largely by the Registry of Standard Biological Parts, careful consideration of future goals may lead to integrated multi- scale approaches to biology. Here we describe some of the current challenges that need to be addressed or considered in detail to continue the development of synthetic biology. Specifically, discussion on the areas of elucidating biological principles, computational methods and experimental construction methodologies are presented. PMID:21326830

    During the history of space exploration, ever improving instruments have continued to enable new measurements and discoveries. Focusing on plasma sensors, we examine the processes by which such new instrument innovations have occurred over the past decades. Due to risk intolerance prevalent in many NASA space missions, innovations in plasma instrumentation occur primarily when heritage systems fail to meet science requirements, functional requirements as part of its space platform, or design constraints. We will review such innovation triggers in the context of the design literature and with the help of two case studies, the Fast Imaging Plasma Spectrometer on MErcury Surface, Space ENvironment, GEochemistry, and Ranging and the Fast Plasma Investigation on Magnetosphere Multiscale. We will then discuss the anticipated needs for new plasma instrument innovations to enable the science program of the next decade.

  14. Surface Reflectance and Ocean Temperature

    NASA Technical Reports Server (NTRS)

    2002-01-01

    MODIS's 36 spectral bands provide scientists the chance to study many of Earth's terrestrial and oceanic characteristics with a single instrument, for example, Sea Surface Temperature (SST) and Land Surface Reflectance (LSR). This image was made from data collected during the month of May 2001. The LSR portion of the image is made from data collected at three wavelengths: 645 nm (red), 555 nm (green), and 469 nm (blue). This combination is similar to what our eyes would see. Combined with the land surface data are MODIS's measurements of SST in May, using detectors that capture thermal radiation at 4.0 um, a design innovation that improves measurements in moist areas, such as the tropics, where persistent clouds often interfere with satellite measurements of SST. Large-scale temperature patterns are apparent, such as the Gulf Stream off the east coast of the United States, and the Kuroshio Circulation southeast of Japan

  16. Open-market innovation.

    PubMed

    Rigby, Darrell; Zook, Chris

    2002-10-01

    Companies in many industries are feeling immense pressure to improve their ability to innovate. Even in these tough economic times, executives have pushed innovation initiatives to the top of their priority lists, but they know that the best ideas aren't always coming out of their own R&D labs. That's why a growing number of companies are exploring the idea of open-market innovation--an approach that uses tools such as licensing, joint ventures, and strategic alliances to bring the benefits of free trade to the flow of new ideas. For instance, when faced with the unanticipated anthrax scare last fall, Pitney Bowes had nothing in its R&D pipeline to help its customers combat the deadly spores. So it sought help from outside innovators to come up with scanning and imaging technologies that could alert its customers to tainted letters and packages. And Dow Chemical and Cargill jointly produced a new form of plastic derived from plant starches--a breakthrough product that neither company could have created on its own. In this article, Bain consultants Darrell Rigby and Chris Zook describe the advantages and disadvantages of open-market innovation and the ways some companies are using it to gain competitive advantage. By importing ideas from the outside, the authors say, companies can collect more and better ideas from different kinds of experts. Creative types within a company will stick around longer if they know their ideas will eventually find a home--as internal R&D projects or as concepts licensed to outside buyers. Exporting ideas also gives companies a way to measure an innovation's real value. However, the authors warn against entering into open-market innovation without properly structuring deals: Xerox and TRW virtually gave away their innovations and had to stand by while other companies capitalized on them.

  20. Homosexuality, biology, and ideology.

    PubMed

    Haumann, G

    1995-01-01

    This paper critically examines the complex relationships and interdependencies between biological theories on homosexuality and sociosexual ideologies. It challenges the privileged status of biology as the ultimate authority on homosexuality. This status is based on the belief that biology is a value-free science. On the contrary, this essay shows how unacknowledged assumptions and culturally bound patterns of thinking about sexuality taint biological research. Sociosexual ideologies are defined as principles that organize the ways we express our sexualities and the way we theorize about them in biology. The following ideologies are identified: (1) sexuality-as-heterosexuality, (2) sexuality-as-reproduction, (3) sexual dualism (male vs. female), and (4) the view the homosexuality is a sexual inversion. The process by which these ideologies are incorporated into biology is two-fold: (1) as a projective act from society onto nature and (2) as a reflective act from nature back into society. It is further argued that biological knowledge of homosexuality resulting from that process can be used for diverse political interests. Finally, it is proposed that since biological theories on homosexuality are inseparable from the context of their paradigmatic origin, it is possible that new theories could be derived from new ideologies.

    The objectives of this study were to assess the applicability of patents and publications as metrics of surgical technology and innovation; evaluate the historical relationship between patents and publications; develop a methodology that can be used to determine the rate of innovation growth in any given health care technology. The study of health care innovation represents an emerging academic field, yet it is limited by a lack of valid scientific methods for quantitative analysis. This article explores and cross-validates 2 innovation metrics using surgical technology as an exemplar. Electronic patenting databases and the MEDLINE database were searched between 1980 and 2010 for "surgeon" OR "surgical" OR "surgery." Resulting patent codes were grouped into technology clusters. Growth curves were plotted for these technology clusters to establish the rate and characteristics of growth. The initial search retrieved 52,046 patents and 1,801,075 publications. The top performing technology cluster of the last 30 years was minimally invasive surgery. Robotic surgery, surgical staplers, and image guidance were the most emergent technology clusters. When examining the growth curves for these clusters they were found to follow an S-shaped pattern of growth, with the emergent technologies lying on the exponential phases of their respective growth curves. In addition, publication and patent counts were closely correlated in areas of technology expansion. This article demonstrates the utility of publically available patent and publication data to quantify innovations within surgical technology and proposes a novel methodology for assessing and forecasting areas of technological innovation.

  3. Toward a Curriculum Innovation

    2008-05-01

    This paper proposes an innovation on HIV prevention, in response to the United Nations Millennium Development Goal to combat HIV/AIDS. The curriculum innovation is through a participatory research design of life skills based education course, involving both healthy faculty tutors and young community leaders at the centre. The innovation builds onto the strengths of previous IIV prevention interventions and argues that effective life skills based education targets the individual, peers and the wider community since the same levels are crucial in HIV transmission. The innovation also recommends a rethinking of the content used to teach and learn life skill based education to prevent HIV and recommends that such content is to be co-conducted by the young community involvement. The content is to be delivered in a participatory way in order for the young community leaders to engage in critical action to prevent HIV. Because of the novelty of such an intervention, the innovation recognizes that such an approach to the design and implementation of the curriculum initiative is complex and involves careful planning, monitoring and evaluation to yield desired outcomes. In conclusion, the innovation recommends that HIV prevention can be possible even in a country such as Sierra Leone, with increasing HIV prevalence in the world.

    "How do I find innovative people for my organization? And how can I become more innovative myself?" These are questions that stump most senior executives, who know that the ability to innovate is the "secret sauce" of business success. Perhaps for this reason most of us stand in awe of the work of visionary entrepreneurs such as Apple's Steve Jobs, Amazon's Jeff Bezos, eBay's Pierre Omidyar, and P&G's A.G. Lafley. How do these individuals come up with groundbreaking new ideas? In this article, Dyer, of Brigham Young University; Gregersen, of Insead; and Christensen, of Harvard Business School, reveal how innovative entrepreneurs differ from typical executives. Their study demonstrates that five "discovery skills" distinguish the most creative executives: Associating helps them discover new directions by making connections among seemingly unrelated questions, problems, or ideas. Questioning allows innovators to break out of the status quo and consider new ideas. Through observing, innovators carefully and consistently look out for small behavioral details--in the activities of customers, suppliers, and other companies -to gain insights about new ways of doing things. In experimenting, they relentlessly try on new experiences and explore the world. And through networking with diverse individuals from an array of backgrounds, they gain radically different perspectives.

    Biomedical advances are transforming the diagnosis and treatment of disease. Patienthood is also transforming, as patients actively participate in research, innovation and regulation of novel technologies and therapies. In this paper we explore the new kinds of practices that patients are performing in their roles as research subject, co-researchers, donors, campaigners, representatives and consumers of novel stratified therapies. We outline their embodied contributions to clinical trials, biobanks and stratified therapies prior to, during and after having cancer. Exploring how patienthood involves donating more than tissue or data to these developments, we consider their emotional and identity work which informs and shapes the novel diagnostics and therapies being developed. We also consider how this kind of work is stratified according to the social and biological location of participants, and end by reflecting on the implications of our analysis for the organisation and regulation of biomedicine.

    Overington, Sarah E; Cauchard, Laure; Côté, Kimberly-Ann; Lefebvre, Louis

    2011-07-01

    Innovative foraging behaviour has been observed in many species, but little is known about how novel behaviour emerges or why individuals differ in their propensity to innovate. Here, we investigate these questions by presenting 36 wild-caught adult male Carib grackles (Quiscalus lugubris) with a novel problem-solving task. Twenty birds solved the task ("innovators") while 16 did not ("non-innovators"). We compared innovators to non-innovators and explored variation in latency to innovate to determine the characteristics of an innovative bird. Innovativeness was not predicted by any morphological trait, but innovators had higher exploration scores and lower object neophobia scores than non-innovators. Within the innovators, latency to innovate was positively correlated with learning speed. Video analysis also revealed a marked difference in the way individuals interacted with the novel apparatus: when innovators contacted the correct part of the apparatus, they continued to do so until they solved the problem. Non-innovators often contacted the correct part of the apparatus, but did not persist in doing so. The importance of obstacle movement cues was confirmed by an experiment where they were manipulated.

    Nicol, Jacqueline Sian; Dosser, Isabel

    2016-05-04

    The Nursing and Midwifery Council (NMC) requires that nurses and midwives use feedback as an opportunity for reflection and learning, to improve practice. The NMC revalidation process stipulates that practitioners provide examples of how they have achieved this. To reflect in a meaningful way, it is important to understand what is meant by reflection, the skills required, and how reflection can be undertaken successfully. Traditionally, reflection occurs after an event encountered in practice. The authors challenge this perception, suggesting that reflection should be undertaken before, during and after an event. This article provides practical guidance to help practitioners use reflective models to write reflective accounts. It also outlines how the reflective process can be used as a valuable learning tool in preparation for revalidation.

    The nursing profession is patient-centered and responsible to meet the disparate health needs of a wide range of client "groups". Ensuring continued innovation and change to further improve care quality in an evolving health care system is an important issue. A focus on resolving minor points rather than on achieving major change may be the best approach to realizing continuous innovation in nursing. The advantages include not only promoting nursing quality and decreasing costs and manpower, but also giving satisfaction and self-fulfillment to the innovator. Successful innovation is affected by environmental structural support as well as the characteristics of the innovation and innovator. A successful innovator is sensitive to each opportunity, but is not a risk creator. This article describes innovator characteristics and innovation execution, and investigates the content and process of nursing innovation from various points of view in order to create new ideas and values related to the traditional nursing role.

  17. Reflecting on reflection: a personal encounter.

    1995-02-01

    This paper reports a retrospective study of a Senior Lecturer in Nursing Studies experience of supervising a student teacher who, as part of her teaching placement experience, utilised 'Critically Reflective Analysis of an Educational Event' as a means to assess her teaching in the practice setting. The Senior Lecturer and student nurse teacher used an external 'advisor' to facilitate their meta-reflection on the theoretical perspectives that informed the process in which they were engaged. The paper raises the following questions for consideration--What is the link between ability to reflect and quality of practice? Is it possible to utilise reflective tutorials as a means of assessing professional competence whilst at the same time encouraging personal and professional development? Is the ability to reflect on practice dependent on the context? Should we assume that all practitioners have the necessary skills to supervise students in practice and what preparation and support is needed? The paper demonstrates that by introducing 'Critically Reflective Analysis of an Education Event' into the student teachers' curriculum the role of both supervisor and student teacher was challenged and changed. The paper also demonstrates that reflective tutorials are not wholly a retrospective business. They are creative, or recreative of a teaching experience, as well as to some extent representing it. Finally, even if one cannot speak in Kuhnian parlance, of a conceptual revolution, it would seem legitimate to say, in Schon's terms, that the contextual frame in which professional problems are addressed has undergone significant change.

    Adhesion can be quantified by measuring the distance between the interacting surfaces. Reflection interference contrast microscopy (RICM), with its ability to measure inter-surface distances under water with nanometric precision and milliseconds time resolution, is ideally suited to studying the dynamics of adhesion in soft systems. Recent technical developments, which include innovative image analysis and the use of multi-coloured illumination, have led to renewed interest in this technique. Unambiguous quantitative measurements have been achieved for colloidal beads and model membranes, thus revealing new insights and applications. Quantification of data from cells shows exciting prospects. Herein, we review the basic principles and recent developments of RICM applied to studies of dynamical adhesion processes in soft matter and cell biology and provide practical hints to potential users.

    When artists depict a mirror in a painting, it necessarily lacks the most obvious property of a mirror: as we move around the painting of the mirror, the reflections we see in it do not change. And yet representations of mirrors and other reflecting surfaces can be quite convincing in paintings. Here, we will examine the rules of reflection, the many ways that painters can break those rules without losing the impression of reflection and the rules that cannot be broken. The rules that govern the perception of reflection are a small subset of the physical rules of reflection. PMID:18534102

    Purpose: Ultraviolet phototherapy is a widely used treatment which has exceptional success with a variety of skin conditions. Over-exposure to ultraviolet radiation (UVR) can however be detrimental and cause side effects such as erythema, photokeratisis, and even skin cancer. Quantifying patient dose is therefore imperative to ensure biologically effective treatment while minimizing negative repercussions. A dose model for treatment would be valuable in achieving these ends. Methods: Prior work by the authors concentrated on modeling the output of the lamps used in treatment and it was found a line source model described the output from the sources to a high degree. In practice, these lamps are surrounded by reflective anodized aluminum in patient treatment cabins and this work extends the model to quantify specular reflections from these planes on patient dose. Results: The extension of the model to allow for reflected images in addition to tube output shows a remarkably good fit to the actual data measured. Conclusions: The reflection model yields impressive accuracy and is a good basis for full UVR cabin modeling.

  4. Biological Races in Humans

    Templeton, Alan R.

    Races may exist in humans in a cultural sense, but biological concepts of race are needed to access their reality in a non-species-specific manner and to see if cultural categories correspond to biological categories within humans. Modern biological concepts of race can be implemented objectively with molecular genetic data through hypothesis-testing. Genetic data sets are used to see if biological races exist in humans and in our closest evolutionary relative, the chimpanzee. Using the two most commonly used biological concepts of race, chimpanzees are indeed subdivided into races but humans are not. Adaptive traits, such as skin color, have frequently been used to define races in humans, but such adaptive traits reflect the underlying environmental factor to which they are adaptive and not overall genetic differentiation, and different adaptive traits define discordant groups. There are no objective criteria for choosing one adaptive trait over another to define race. As a consequence, adaptive traits do not define races in humans. Much of the recent scientific literature on human evolution portrays human populations as separate branches on an evolutionary tree. A tree-like structure among humans has been falsified whenever tested, so this practice is scientifically indefensible. It is also socially irresponsible as these pictorial representations of human evolution have more impact on the general public than nuanced phrases in the text of a scientific paper. Humans have much genetic diversity, but the vast majority of this diversity reflects individual uniqueness and not race. PMID:23684745

    Multidrug-resistant bacterial diseases pose serious and growing threats to human health. While innovation is important to all areas of health research, it is uniquely important in antibiotics. Resistance destroys the fruit of prior research, making it necessary to constantly innovate to avoid falling back into a pre-antibiotic era. But investment is declining in antibiotics, driven by competition from older antibiotics, the cost and uncertainty of the development process, and limited reimbursement incentives. Good public health practices curb inappropriate antibiotic use, making return on investment challenging in payment systems based on sales volume. We assess the impact of recent initiatives to improve antibiotic innovation, reflecting experience with all sixty-seven new molecular entity antibiotics approved by the Food and Drug Administration since 1980. Our analysis incorporates data and insights derived from several multistakeholder initiatives under way involving governments and the private sector on both sides of the Atlantic. We propose three specific reforms that could revitalize innovations that protect public health, while promoting long-term sustainability: increased incentives for antibiotic research and development, surveillance, and stewardship; greater targeting of incentives to high-priority public health needs, including reimbursement that is delinked from volume of drug use; and enhanced global collaboration, including a global treaty.

    2015-03-01

    The spectral and angle-dependent optical properties of two scarab beetle species belonging to the genus Chrysina are presented. The species display broadband reflectivity and selectively reflect left-circularly polarized light. We use electron microscopy to detail the left-handed, twisted lamellar structure present in these biological systems and imaging scatterometry to characterize their bidirectional reflectance distribution function. We show that the broadband nature of the beetles' reflectance originates due to the range of pitch dimensions found in the structure.

  16. Macro trends in pharmaceutical innovation.

    PubMed

    Cohen, Fredric J

    2005-04-01

    Extract: A lately recycled criticism of the pharmaceutical industry is that it is failing in its mission to innovate. In particular, critics question the industry's incentives to innovate, and they deride those innovations the industry makes as imitative. Industry advocates contend the opposite. The truth is that there are no generally accepted measures of innovation that would conclusively prove either side's point. However, I have found trends in several measures that support both sides of the innovation debate. Overall, the bulk of evidence suggests that the pharmaceutical industry continues to regard pioneering innovations as important (evidenced by the motivation, effort and ability of the industry to create such innovations). However, like other mature manufacturing industries, the pharmaceutical industry relies heavily on incremental innovations (what critics call "me-too" drugs) to sustain its profits. To a large extent, these incremental innovations are themselves medically beneficial and should be encouraged rather than dismissed as merely imitative.

  18. On innovations in plastic surgery.

    PubMed

    Mehta, Hemant

    2009-04-01

    The progress of surgery has been utterly dependent on continuing innovations by surgeon innovators, largely because surgeons work in an environment that is very conducive to innovating. Of all clinicians surgeons excel at improvisations and innovations. The aim of this review is to outline some of my innovations, the circumstances leading to their origin, and to explain some of the fundamental concepts behind those innovations, with a view to inviting and encouraging younger surgeons to consider breaking away - sensibly - from convention at times, and embark on a journey towards innovation. The context and the qualities required of a would-be innovator are explained and the process of innovation itself is analysed. Rigid adherence to prevailing assumptions and practices stifles originality, while adopting a questioning attitude with a smidgen of irreverence facilitates innovation. That an innovation has resulted purely by a chance observation or occurrence - serendipity - may render it less glamorous but never less useful. Innovations in surgical techniques necessitate adoption of a novel pragmatic surgical philosophy. Confined as they are to Oculoplasty, the concepts of innovations cited and illustrated in this review, are equally valid for Plastic surgery and indeed for Surgery in general. Working in a small hospital or an isolated Institution need not be a hindrance to a would-be innovator.

    The purpose of this article is to suggest a (preliminary) taxonomy and research agenda for the topic of "firms, crowds, and innovation" and to provide an introduction to the associated special issue. We specifically discuss how various crowd-related phenomena and practices-for example, crowdsourcing, crowdfunding, user innovation, and peer production-relate to theories of the firm, with particular attention on "sociality" in firms and markets. We first briefly review extant theories of the firm and then discuss three theoretical aspects of sociality related to crowds in the context of strategy, organizations, and innovation: (1) the functions of sociality (sociality as extension of rationality, sociality as sensing and signaling, sociality as matching and identity), (2) the forms of sociality (independent/aggregate and interacting/emergent forms of sociality), and (3) the failures of sociality (misattribution and misapplication). We conclude with an outline of future research directions and introduce the special issue papers and essays.

    Despite advances in renal replacement therapy, the adequate removal of uremic toxins over a broad molecular weight range remains one of the unmet needs in hemodialysis. Therefore, membrane innovation is currently directed towards enhanced removal of uremic toxins and increased membrane permeability. This chapter presents a variety of opportunities where innovation is brought into dialysis membranes. It covers the membrane formation from solution, describing different approaches to control the phase inversion process through additives that either swell in the polymer solution or influence the pore shrinkage during the membrane drying process. Additionally, large-scale manufacturing is described, and the influence of raw materials, spinning, and drying processes on membrane selectivity are presented. Finally, new characterization methods developed for the latest innovations around the application of membranes in dialysis are discussed, which allow the membrane performance for removal of a broad range of uremic toxins and the expected albumin loss in clinical use. © 2017 S.

  1. Innovating for cash.

    PubMed

    Andrew, James P; Sirkin, Harold L

    2003-09-01

    Despite companies' almost fanatical worship of innovation, most new products don't generate money. That's because executives don't realize that the approach they take to commercializing a new product is as important as the innovation itself. Different approaches can generate very different levels of profit. Companies tend to favor one of three different innovation approaches, each with its own investment profile, profitability pattern, risk profile, and skill requirements. Most organizations are instinctively integrators: They manage all the steps needed to take a product to market themselves. Organizations can also choose to be orchestrators: They focus on some parts of the commercialization process and depend on partners to manage the rest. And finally, companies can be licensers: They sell or license a new product or idea to another organization that handles the commercialization process. Different innovations require different approaches. Selecting the most suitable approach, the authors' research found, often yields two or three times the profits of the least optimal approach. Yet companies tend to rely only on the mode most familiar to them. Executives would do better to take several different factors into account before deciding which tack to take, including the industry they're trying to enter, the specific characteristics of the innovation, and the risks involved in taking the product to market. By doing so, companies can match the approach to the opportunity and reap the maximum profit. Choosing the wrong approach, like Polaroid did, for example, can lead to the failure of both the product and the company. Optimizing their approaches, as Whirlpool has done, helps ensure that companies' innovations make money.

    Biological weapons are weapons of mass destruction that use pathogens (bacteria, viruses) or the toxins produced by them to target living organisms or to contaminate non-living substances. In the past, biological warfare has been repeatedly used. Anthrax, plague and smallpox are regarded as the most dangerous biological weapons by various institutions. Nowadays it seems quite unlikely that biological warfare will be employed in any military campaigns. However, the possibility remains that biological weapons may be used in acts of bioterrorism. In addition all diseases caused by biological weapons may also occur naturally or as a result of a laboratory accident. Risk assessment with regard to biological danger often proves to be difficult. In this context, an early identification of a potentially dangerous situation through experts is essential to limit the degree of damage. Georg Thieme Verlag KG Stuttgart * New York.

    The scholarly dissemination of innovative medical education practices helps broaden the reach of this type of work, allowing scholarship to have an impact beyond a single institution. There is little guidance in the literature for those seeking to publish program evaluation studies and innovation papers. This study aims to derive a set of evidence-based features of high-quality reports on innovations in emergency medicine (EM) education. We conducted a scoping review and thematic analysis to determine quality markers for medical education innovation reports, with a focus on EM. A search of MEDLINE, EMBASE, ERIC, and Google Scholar was augmented by a hand search of relevant publication guidelines, guidelines for authors, and website submission portals from medical education and EM journals. Study investigators reviewed the selected articles, and a thematic analysis was conducted. Our search strategy identified 14 relevant articles from which 34 quality markers were extracted. These markers were grouped into seven important themes: goals and need for innovation, preparation, innovation development, innovation implementation, evaluation of innovation, evidence of reflective practice, and reporting and dissemination. In addition, multiple outlets for the publication of EM education innovations were identified and compiled. The publication and dissemination of innovations are critical for the EM education community and the training of health professionals. We anticipate that our list of innovation report quality markers will be used by EM education innovators to support the dissemination of novel educational practices.
