    Ethics in biomedical research took off from the 1947 Nuremberg Code to its own right in the wake of the Declaration of Helsinki in 1964. Since then, (inter)national regulations and guidelines providing a framework for clinical studies and protection for study participants have been drafted and implemented, while ethics committees and drug evaluation agencies have sprung up throughout the world. These two developments were crucial in bringing about the protection of rights and safety of the participants and harmonization of the conduct of biomedical research. Ethics committees and drug evaluation agencies deliver ethical and scientific assessments on the quality and safety of the projects submitted to them and issue respectively approvals and authorizations to carry out clinical trials, while ensuring that they comply with regulatory requirements, ethical principles, and scientific guidelines. The advent of biomedical ethics, together with the responsible commitment of clinical investigators and of the pharmaceutical industry, has guaranteed respect for the patient, for whom and with whom research is conducted. Just as importantly, it has also ensured that patients reap the benefit of what is the primary objective of biomedical research: greater life expectancy, well-being, and quality of life.

    Objectives Successful aging continues to be applied in a variety of contexts and is defined using a number of different constructs. Although previous reviews highlight the multidimensionality of successful aging, a few have focused exclusively on non-biomedical factors, as was done here. Methods This scoping review searched Ovid Medline database for peer-reviewed English-language articles published between 2006 and 2015, offering a model of successful aging and involving research with older adults. Results Seventy-two articles were reviewed. Thirty-five articles met the inclusion criteria. Common non-biomedical constructs associated with successful aging included engagement, optimism and/or positive attitude, resilience, spirituality and/or religiosity, self-efficacy and/or self-esteem, and gerotranscendence. Discussion Successful aging is a complex process best described using a multidimensional model. Given that the majority of elders will experience illness and/or disease during the life course, public health initiatives that promote successful aging need to employ non-biomedical constructs, facilitating the inclusion of elders living with disease and/or disability.

  5. NASA's Biomedical Research Program

    NASA Technical Reports Server (NTRS)

    1981-01-01

    The biomedical research program has been established to investigate the major physiological and psychological problems encountered by man when he undertakes spaceflight. The program seeks to obtain a better definition of each problem, an understanding of its underlying mechanism, and ultimately a means of prevention. In pursuing these goals the program also includes a major effort to develop the research tools and procedures it needs where these are not being developed elsewhere. After almost twenty years of manned spaceflight activities and after a much longer period of space related ground-based research, the program now recognizes two characteristics of spaceflight which are truly unique to space. These are weightlessness and one specific form of radiation. In its present stage of maturity much of the research focuses on mechanisms underlying the basic responses of man and animals to weightlessness. The program consists of nine elements. Eight of these are referable to specific physiological problems that have either been encountered in previous manned spaceflight or which are anticipated to occur as spaceflights last longer, traverse steeper orbital inclinations, or are otherwise different from previous missions. The ninth addresses problems that have neither arisen nor can be reasonably predicted but are suspected on the basis of theoretical models, ground-based animal research, or for other reasons. The program's current emphasis is directed toward the motion sickness problem because of its relevance to Space Shuttle operations. Increased awareness and understanding of the radiation hazard has resulted in more emphasis being placed on the biological effects of high energy, high mass number particulate radiation and upon radiation protection . Cardiovascular and musculoskeleta1 studies are pursued in recognition of the considerable fundamental knowledge that must be acquired in these areas before effective countermeasures to the effects of repetitive or long

  17. Ethics, regulation, and biomedical research.

    PubMed

    Weed, Matthew

    2004-12-01

    Controversy has surrounded the institutions that facilitate discussion and regulation of American biomedical research for years. Recent challenges to the legitimacy of the President's Council on Bioethics have been focused on stem cell research. These arguments represent an opportunity to reconsider the legislation under which stem cell research is regulated, as well as to consider preexisting bodies like the Recombinant DNA Advisory Committee and National Bioethics Advisory Commission. This paper proposes a Federal Life Sciences Policy Commission, a novel commission with advisory and regulatory powers that would benefit from the positive and negative lessons learned under the legislation that currently shapes the formation and institutional characteristics of advisory bodies in the United States. The Federal Life Sciences Policy Commission would have institutional independence not present in previous advisory bodies, while maintaining the tradition of broad societal representation and thoughtful discourse that has developed in the United States.

  18. Educating about biomedical research ethics.

    Stankovic, Bratislav; Stankovic, Mirjana

    2014-11-01

    This article examines the global and worsening problem of research misconduct as it relates to bio-medico-legal education. While research misconduct has serious legal implications, few adequate legal remedies exist to deal with it. With respect to teaching, research ethics education should be mandatory for biomedical students and physicians. Although teaching alone will not prevent misconduct, it promotes integrity, accountability, and responsibility in research. Policies and law enforcement should send a clear message that researchers should adhere to the highest standards of ethics in research. It is vital that researchers and physicians understand basic aspects of law and the legal system in order to develop understanding of the medico-legal issues not just in the legal context, but with a sound grounding in ethics, social and theoretical contexts so that they can practice good medicine. Routine and holistic research ethics education across the curriculum for medical students and resident physicians, and continuing medical education for practicing doctors, are probably the best ways to accomplish this goal.

Setting 10 UK biomedical research funders. Participants 12 employees with responsibility for research management at 10 UK biomedical research funders; a purposive sample to represent a range of backgrounds and organisation types. Conclusions Publicly funded and large biomedical research funders are committed to open access publishing and are pleased with recent developments which have stimulated growth in this area. Smaller charitable funders are supportive of the aims of open access, but are concerned about the practical implications for their budgets and their funded researchers. Across the board, biomedical research funders are turning their attention to other priorities for sharing research outputs, including data, protocols and negative results. Further work is required to understand how smaller funders, including charitable funders, can support open access. PMID:24154520

  20. Animals in biomedical space research

    NASA Astrophysics Data System (ADS)

    Phillips, Robert W.

    The use of experimental animals has been a major component of biomedical research progress. Using animals in space presents special problems, but also provides special opportunities. Rat and squirrel monkeys experiments have been planned in concert with human experiments to help answer fundamental questions concerning the effect of weightlessness on mammalian function. For the most part, these experiments focus on identified changes noted in humans during space flight. Utilizing space laboratory facilities, manipulative experiments can be completed while animals are still in orbit. Other experiments are designed to study changes in gravity receptor structure and function and the effect of weightlessness on early vertebrate development. Following these preliminary animals experiments on Spacelab Shuttle flights, longer term programs of animal investigation will be conducted on Space Station.

    1976-01-01

    A meeting on Marine Biomedical Research, sponsored by the National Institute of Environmental Health Sciences (NIEHS), National Institutes of Health and the Smithsonian Institution Museum of Natural History, was attended by approximately 125 scientists, directors and representatives from many of the country's marine biological laboratories, and government agencies whose interests and responsibilites are in the marine biology and health areas. The purpose of the meeting was to explore the undeveloped research opportunities in the area of marine biology for the advancement of our understanding of human health problems and to provide information on the current status of marine biology laboratories. The meeting was devoted to presentations and discussions in four general areas: (1)Marine Species as Models for Human Disease; (2)Environmental Carcinogenesis and Mutagenesis; (3)Human Health and the Marine Environment--infectious agents and naturally occurring and foreign toxins; and (4)Drugs from the seas. Representatives from twelve of the country's approximatley 40 marine laboratories discussed their organization, developmental history, scientific programs, facilities, and present status of their support. The presentations served as a background and stimulated very lively analytical and constructive discussions of the undeveloped research and education potential residing in the marine environment and biological laboratories for a better understanding of many human health problems; some scientific areas that should be developed to realize this potential; and the needs and problems of marine laboratories that require attention and support if they are to survive and realize their possibilities.

    The evaluation of R + D activities and the politics that promote them is essential to justify the investment done as well as to optimize their results. In this context, the evaluation should be understood as the group of techniques and procedures that allow obtaining useful information to take decisions in the field of R + D. This article has two main objectives: (i) to present the basic concepts associated with the evaluation of research, and (ii) to offer a general and updated panoramic view of which are the most frequently used methods to evaluate research. For that, in addition to considering the most conventional evaluation, focused on scientific results, we also think about the need of evaluating the impacts that scientific results generate on the social-economic context, and that in the case of biomedical research, these may be presented in terms of quality and life expectancy, improvements in patient care, etc. Therefore, the motivation of present article is to give a modern and updated perspective that allows the reader who is interested to study in-depth this emerging field of Science, if he/she wants.

  3. Evaluation of research in biomedical ontologies.

    2013-11-01

    Ontologies are now pervasive in biomedicine, where they serve as a means to standardize terminology, to enable access to domain knowledge, to verify data consistency and to facilitate integrative analyses over heterogeneous biomedical data. For this purpose, research on biomedical ontologies applies theories and methods from diverse disciplines such as information management, knowledge representation, cognitive science, linguistics and philosophy. Depending on the desired applications in which ontologies are being applied, the evaluation of research in biomedical ontologies must follow different strategies. Here, we provide a classification of research problems in which ontologies are being applied, focusing on the use of ontologies in basic and translational research, and we demonstrate how research results in biomedical ontologies can be evaluated. The evaluation strategies depend on the desired application and measure the success of using an ontology for a particular biomedical problem. For many applications, the success can be quantified, thereby facilitating the objective evaluation and comparison of research in biomedical ontology. The objective, quantifiable comparison of research results based on scientific applications opens up the possibility for systematically improving the utility of ontologies in biomedical research.

    2009-01-01

    The prevailing view is that participation in biomedical research is above and beyond the call of duty. While some commentators have offered reasons against this, we propose a novel public goods argument for an obligation to participate in biomedical research. Biomedical knowledge is a public good, available to any individual even if that individual does not contribute to it. Participation in research is a critical way to support that important public good. Consequently, we all have a duty to participate. The current social norm is that people participate only if they have a good reason to do so. The public goods argument implies that people should participate unless they have a good reason not to. Such a shift would be of great aid to the progress of biomedical research, eventually making our society significantly healthier and longer-lived. PMID:19567441

    Several human characteristics that influence scientific research performance, including set goals, mental and physical abilities, education, and experience, may vary considerably during the life cycle of scientists. We sought to answer the question of whether high-quality research productivity is associated with investigator's age. We randomly selected 300 highly cited scientists (50 from each of 6 different biomedical fields, specifically immunology, microbiology, neuroscience, psychology-psychiatry, clinical medicine, and biology-biochemistry). Then, we identified the top 5 highly cited articles (within 10 yr after publication adjusted for the expansion of the literature) as first author of each of them. Subsequently, we plotted the distribution of the 1500 analyzed articles of the 300 studied scientists in the eight 5-year intervals of investigator's age during the year of article publication (21-25 to 55-60 yr of age), adjusted for person-years of contribution of each scientist in the various age groups. Highly cited research productivity plotted a curve that peaked at the age group of 31-35 yr of age and then gradually decreased with advancing age. However, a considerable proportion of this highly cited research was produced by older scientists (in almost 20% of the analyzed articles, researchers were older than 50 yr). The results were similar in another analysis of the single most cited article of each studied scientist. In conclusion, high-quality scientific productivity in the biomedical fields as a function of investigator's age plots an inverted U-shaped curve, in which significant decreases take place from around 40 yr of age and beyond.

    2007-03-01

    This review covers the applications of small-molecule and peptidic compounds isolated from marine organisms for biomedical research. Enzymes and proteins from marine sources are already on the market for biomedical applications, but the use of small-molecule biomedical research tools of marine origin is less developed. For many studies involving these molecules the ultimate goal is the application of small-molecule therapeutics in the clinic, but those that do not succeed in the clinic still have clearly defined biological activities, which may be of use as biomedical research tools. In other cases, the investigation of marine-derived compounds has led directly to the discovery of therapeutics with clinical applications. Both as tools and therapeutics, these small-molecule compounds are effective for investigating biological processes, and in this review the authors have chosen to concentrate on the ability of marine natural products to affect membrane processes, ion channels and intracellular processes.

    PubMed

    Sherman, Michael A; Seth, Ajay; Delp, Scott L

    Multibody software designed for mechanical engineering has been successfully employed in biomedical research for many years. For real time operation some biomedical researchers have also adapted game physics engines. However, these tools were built for other purposes and do not fully address the needs of biomedical researchers using them to analyze the dynamics of biological structures and make clinically meaningful recommendations. We are addressing this problem through the development of an open source, extensible, high performance toolkit including a multibody mechanics library aimed at the needs of biomedical researchers. The resulting code, Simbody, supports research in a variety of fields including neuromuscular, prosthetic, and biomolecular simulation, and related research such as biologically-inspired design and control of humanoid robots and avatars. Simbody is the dynamics engine behind OpenSim, a widely used biomechanics simulation application. This article reviews issues that arise uniquely in biomedical research, and reports on the architecture, theory, and computational methods Simbody uses to address them. By addressing these needs explicitly Simbody provides a better match to the needs of researchers than can be obtained by adaptation of mechanical engineering or gaming codes. Simbody is a community resource, free for any purpose. We encourage wide adoption and invite contributions to the code base at https://simtk.org/home/simbody.

We also review the implications that the National Plan of Quality has had on university research, clearly stimulating and improving the system, and new transformations that the Organic Law of Universities brings implied, and more specifically the National System of Qualification for the access to university teaching staff, which has research work of the teachers as the essential key. Finally, we review the biomedical scientific production during the last years by topics and universities, reflecting the improvement seen during the last decade not only in quantity but also in quality, which is more important. In conclusion, the review reflects a notable change in biomedical research in our universities opening an encouraging track for the future of research.

    The thesis presented here is that biomedical research is based on the trusted exchange of services. That exchange would be conducted more efficiently if the trusted software platforms to exchange those services, if they exist, were more integrated. While simpler and narrower in scope than the services governing biomedical research, comparison to existing internet-based platforms, like Airbnb, can be informative. We illustrate how the analogy to internet-based platforms works and does not work and introduce The Commons, under active development at the National Institutes of Health (NIH) and elsewhere, as an example of the move towards platforms for research.

    The contributions published in Revista de Biología Tropical in the area of Biomedical Sciences are reviewed in terms of number of contributions and scope of research subjects. Biomedical Sciences, particularly Parasitology and Microbiology, constituted the predominant subject in the Revista during the first decade, reflecting the intense research environment at the School of Microbiology of the University of Costa Rica and at Hospital San Juan de Dios. The relative weight of Biomedicine in the following decades diminished, due to the outstanding increment in publications in Biological Sciences; however, the absolute number of contributions in Biomedical Sciences remained constant throughout the last decades, with around 80 contributions per decade. In spite of the predominance of Parasitology as the main biomedical subject, the last decades have witnessed the emergence of new areas of interest in the Revista, such as Pharmacology of natural products, Toxinology, especially related to snake venoms, and Human Genetics. This retrospective analysis evidences that Biomedical Sciences, particularly those related to Tropical Medicine, were a fundamental component during the first years of Revista de Biología Tropical, and have maintained a significant presence in the scientific output of this journal, the most relevant scientific publication in biological sciences in Central America.

    Biomedical engineering is a new area of research in medicine and biology, providing new concepts and designs for the diagnosis, treatment and prevention of various diseases. There are several types of biomedical engineering, such as tissue, genetic, neural and stem cells, as well as chemical and clinical engineering for health care. Many electronic and magnetic methods and equipments are used for the biomedical engineering such as Computed Tomography (CT) scans, Magnetic Resonance Imaging (MRI) scans, Electroencephalography (EEG), Ultrasound and regenerative medicine and stem cell cultures, preparations of artificial cells and organs, such as pancreas, urinary bladders, liver cells, and fibroblasts cells of foreskin and others. The principle of tissue engineering is described with various types of cells used for tissue engineering purposes. The use of several medical devices and bionics are mentioned with scaffold, cells and tissue cultures and various materials are used for biomedical engineering. The use of biomedical engineering methods is very important for the human health, and research and development of diseases. The bioreactors and preparations of artificial cells or tissues and organs are described here.

    Biomedical research is crucial for any country's progress and the health of its ethnic population. This effort needs to be sustained and well supported for it to bear optimum results. The major stakeholders in medical research are the general public, patients, researchers, physicians (and medical institutions), the pharmaceutical industry, regulatory authorities, and the government. Much of the pressure to perform cutting edge research in developed countries is driven by the general public; however, this has been conspicuous by its absence in India. This is largely due to misconceptions that medical research in developing countries is an experimental exercise using human beings as guinea pigs, primarily benefiting only the pharmaceutical industry and a general lack of awareness about the importance of original research within the country. This editorial addresses various issues related to public involvement in biomedical research and suggests the need for solutions and imperative remedial measures. PMID:27843788

    2000-01-01

    This report summarizes the activities of the National Space Biomedical Research Institute (NSBRI) during FY 2000. The NSBRI is responsible for the development of countermeasures against the deleterious effects of long-duration space flight and performs fundamental and applied space biomedical research directed towards this specific goal. Its mission is to lead a world-class, national effort in integrated, critical path space biomedical research that supports NASA's Human Exploration and Development of Space (HEDS) Strategic Plan by focusing on the enabling of long-term human presence in, development of, and exploration of space. This is accomplished by: designing, testing and validating effective countermeasures to address the biological and environmental impediments to long-term human space flight; defining the molecular, cellular, organ-level, integrated responses and mechanistic relationships that ultimately determine these impediments, where such activity fosters the development of novel countermeasures; establishing biomedical support technologies to maximize human performance in space, reduce biomedical hazards to an acceptable level, and deliver quality medical care; transferring and disseminating the biomedical advances in knowledge and technology acquired through living and working in space to the general benefit of mankind, including the treatment of patients suffering from gravity- and radiation-related conditions on Earth; and ensuring open involvement of the scientific community, industry and the public at large in the Institute's activities and fostering a robust collaboration with NASA, particularly through NASA's Lyndon B. Johnson Space Center. Attachment:Appendices (A,B,C,D,E,F,G,H,I,J,K,L,M,N,O, and P.).

    2013-02-01

    Traditionally, biomedical research has been carried out mainly within departmental boundaries. However, successful biomedical research increasingly relies on development of methods and concepts crossing these boundaries, requiring expertise in different disciplines. Recently, major research institutes have begun experimenting with ways to foster an interdisciplinary ethos. The Evans Center for Interdisciplinary Biomedical Research ("the Evans Center") at Boston University is a new organizational paradigm to address this challenge. The Evans Center is built around interdisciplinary research groups termed affinity research collaboratives (ARCs). Each ARC consists of investigators from several academic departments and at least two research disciplines, bound by a common goal to investigate biomedical problems concerning human disease. Novel aspects of the Evans Center include a "bottom-up" approach to identifying areas of ARC research (research vision and strategy are typically initiated by a core group of faculty with input from the center director); a pre-ARC period of faculty affiliation/project(s)' self-selection prior to formation of a peer-reviewed ARC; and Evans Center support for innovative ARCs for up to three years pending yearly metric evaluation, followed by continued administrative support as a group matures into an ARC program.Since its inception in early 2009, the Evans Center has documented achievements at discovery/publication, grant award, and educational levels. Enhanced interactions between members of individual ARCs, as assessed by quantitative networking analysis, are discussed in the context of high productivity. As universities seek new approaches to stimulate interdisciplinary research, the Evans Center and its ARCs are offered as a productive model for leveraging discovery.

  7. Computational Approaches for Predicting Biomedical Research Collaborations

    Biomedical research is increasingly collaborative, and successful collaborations often produce high impact work. Computational approaches can be developed for automatically predicting biomedical research collaborations. Previous works of collaboration prediction mainly explored the topological structures of research collaboration networks, leaving out rich semantic information from the publications themselves. In this paper, we propose supervised machine learning approaches to predict research collaborations in the biomedical field. We explored both the semantic features extracted from author research interest profile and the author network topological features. We found that the most informative semantic features for author collaborations are related to research interest, including similarity of out-citing citations, similarity of abstracts. Of the four supervised machine learning models (naïve Bayes, naïve Bayes multinomial, SVMs, and logistic regression), the best performing model is logistic regression with an ROC ranging from 0.766 to 0.980 on different datasets. To our knowledge we are the first to study in depth how research interest and productivities can be used for collaboration prediction. Our approach is computationally efficient, scalable and yet simple to implement. The datasets of this study are available at https://github.com/qingzhanggithub/medline-collaboration-datasets.

    As a result of the Leadership Conference on Biomedical Research and the Environment, the Facilities Committee focused its work on the development of best environmental practices at biomedical research facilities at the university and independent research facility level as well as consideration of potential involvement of for-profit companies and government agencies. The designation "facilities" includes all related buildings and grounds, "green auditing" of buildings and programs, purchasing of furnishings and sources, energy efficiency, and engineering services (lighting, heating, air conditioning), among other activities. The committee made a number of recommendations, including development of a national council for environmental stewardship in biomedical research, development of a system of green auditing of such research facilities, and creation of programs for sustainable building and use. In addition, the committee recommended extension of education and training programs for environmental stewardship, in cooperation with facilities managers, for all research administrators and researchers. These programs would focus especially on graduate fellows and other students, as well as on science labs at levels K--12. PMID:11121360

    2015-01-01

    Many scientists complain that the current funding situation is dire. Indeed, there has been an overall decline in support in funding for research from the National Institutes of Health and the National Science Foundation. Within the Drosophila field, some of us question how long this funding crunch will last as it demotivates principal investigators and perhaps more importantly affects the long-term career choice of many young scientists. Yet numerous very interesting biological processes and avenues remain to be investigated in Drosophila, and probing questions can be answered fast and efficiently in flies to reveal new biological phenomena. Moreover, Drosophila is an excellent model organism for studies that have translational impact for genetic disease and for other medical implications such as vector-borne illnesses. We would like to promote a better collaboration between Drosophila geneticists/biologists and human geneticists/bioinformaticians/clinicians, as it would benefit both fields and significantly impact the research on human diseases.

    This article describes a Digital Health Framework (DHF), benefitting from the lessons learnt during the three-year life span of the FP7 Synergy-COPD project. The DHF aims to embrace the emerging requirements - data and tools - of applying systems medicine into healthcare with a three-tier strategy articulating formal healthcare, informal care and biomedical research. Accordingly, it has been constructed based on three key building blocks, namely, novel integrated care services with the support of information and communication technologies, a personal health folder (PHF) and a biomedical research environment (DHF-research). Details on the functional requirements and necessary components of the DHF-research are extensively presented. Finally, the specifics of the building blocks strategy for deployment of the DHF, as well as the steps toward adoption are analyzed. The proposed architectural solutions and implementation steps constitute a pivotal strategy to foster and enable 4P medicine (Predictive, Preventive, Personalized and Participatory) in practice and should provide a head start to any community and institution currently considering to implement a biomedical research platform.

    Captive bred rhesus monkeys show much less pathology than wild born animals. The monkeys may be bred in cages or in an outdoor compound. Cage bred animals are not psychologically normal which makes then unsuited for some types of space related research. Compound breeding provides contact between mother and infant and an opportunity for the infants to play with their peers which are important requirements to help maintain their behavioral integrity. Offspring harvested after a year in the compound appear behaviorally normal and show little histopathology. Compound breeding is also an economical method for the rapid production of young animals. The colony can double its size about every two and a half years.

    The mission of medicine is maintenance of health, elimination of suffering and prolongation of life. These aims can be achieved by medicine based on experimental determination, because only then it becomes a real science. The nature of human mind has led the man since the beginning of humanity on the earth to the cognition of his environment and himself. Being intellectually superior than other living creatures, the man got power over them. In his endless efforts to expand knowledge about living organisms, including his own, he started to use animals. The man has used animals for cognitive purposes for ages and is still doing it, however his motivation has changed and is still changing. Cognition of functions of living organisms on the basis of observation solely, without any interference into the living body gave a lot of important information, yet, generally, this method was of little use for the development of science. Only the use of animals could give information about this what was earlier unknown and impossible. The long-lasting evolution of experimental studies of living functions of higher organisms resulted in achieving a perfect level in biomedical studies. Vivisection, as it was understood years ago, has become history. For a chronic experiment, an animal is surgically prepared according to the researcher's intention. The surgery and the postoperative period follow the principles used in human surgery. After the convalesce period, the animal is used for further experiments. On such prepared animals, the investigations in experimental cardiology, neurophysiology, gastroenterology and other medical disciplines are performed. The animal prepared for longlasting experiments do not suffer from pain during both the experiments and intervals between them. Another important achievement in chronic experiments is considerable reduction of the number of animals used in experimental medicine. Undoubtedly, the greatest achievements in medicine in the 19th and 20th

    Proteins that are important indicators of physiological or pathological states, can provide information for the identification of early and differential markers for disease. Saliva, contains an abundance of proteins, offers an easy, inexpensive, safe, and non-invasive approach for disease detection, and possesses a high potential to revolutionize the diagnostics. Discovery of salivary biomarkers could be used to scrutinize health and disease surveillance. The impact of human saliva proteome analysis in the search for clinically relevant disease biomarkers will be realized through advances made using proteomic technologies. The advancements of emerging proteomic techniques have benefited biomarker research to the point where saliva is now recognized as an excellent diagnostic medium for the detection of disease. This review presents an overview of the value of saliva as a credible diagnostic tool and we aim to summarize the proteomic technologies currently used for global analysis of saliva proteins and to elaborate on the application of saliva proteomics to the discovery of disease biomarkers, and discuss some of the critical challenges and perspectives in this field.

    In the USA, the national cyberinfrastructure refers to a system of research supercomputer and other IT facilities and the high speed networks that connect them. These resources have been heavily leveraged by scientists in disciplines such as high energy physics, astronomy, and climatology, but until recently they have been little used by biomedical researchers. We suggest that many of the ‘Big Data’ challenges facing the medical informatics community can be efficiently handled using national-scale cyberinfrastructure. Resources such as the Extreme Science and Discovery Environment, the Open Science Grid, and Internet2 provide economical and proven infrastructures for Big Data challenges, but these resources can be difficult to approach. Specialized web portals, support centers, and virtual organizations can be constructed on these resources to meet defined computational challenges, specifically for genomics. We provide examples of how this has been done in basic biology as an illustration for the biomedical informatics community. PMID:23964072

    Open access within the scientific community depends on the scientific context and the practices of the field. In the biomedical domain, the communication of research results is characterised by the importance of the peer reviewing process, the existence of a hierarchy among journals and the transfer of copyright to the editor. Biomedical publishing has become a lucrative market and the growth of electronic journals has not helped lower the costs. Indeed, it is difficult for today's public institutions to gain access to all the scientific literature. Open access is thus imperative, as demonstrated through the positions taken by a growing number of research funding bodies, the development of open access journals and efforts made in promoting open archives. This article describes the setting up of an Inserm portal for publication in the context of the French national protocol for open-access self-archiving and in an international context.

    For biomedical researchers to fulfill their responsibility for protecting the environment, they must do more than meet the scientific challenge of reducing the number and volume of hazardous materials used in their laboratories and the engineering challenge of reducing pollution and shifting to cleaner energy sources. They must also meet the public relations challenge of informing and involving their neighbors in these efforts. The experience of the Office of Community Liaison of the National Institutes of Health (NIH) in meeting the latter challenge offers a model and several valuable lessons for other biomedical research facilities to follow. This paper is based on presentations by an expert panel during the Leadership Conference on Biomedical Research and the Environment held 1--2 November 1999 at NIH, Bethesda, Maryland. The risks perceived by community members are often quite different from those identified by officials at the biomedical research facility. The best antidote for misconceptions is more and better information. If community organizations are to be informed participants in the decision-making process, they need a simple but robust mechanism for identifying and evaluating the environmental hazards in their community. Local government can and should be an active and fully informed partner in planning and emergency preparedness. In some cases this can reduce the regulatory burden on the biomedical research facility. In other cases it might simplify and expedite the permitting process or help the facility disseminate reliable information to the community. When a particular risk, real or perceived, is of special concern to the community, community members should be involved in the design, implementation, and evaluation of targeted risk assessment activities. Only by doing so will the community have confidence in the results of those activities. NIH has involved community members in joint efforts to deal with topics as varied as recycling and soil

    Why is technology transfer important for cancer and other biomedical researchers? What do biomedical researchers need to know about technology transfer? This report will address these questions in the context of the United States technology transfer system, which is now approximately 20 years old. To accomplish this goal, this report first summarizes the importance of technology transfer and the role of intellectual property rights. Then it describes the sequential steps in technology transfer from universities to industry. Next, it describes technology transfer from the NIH intramural laboratories and other federal laboratories to industry. Finally, it describes unique aspects of technology transfer involving clinical trials. URL citations to the latest federal guidelines and regulations governing technology transfer are provided. Where appropriate, comparisons will be made with technology transfer systems in other countries. I hope that this step-by-step description of the technology transfer process will enable cancer researchers to play a more proactive role in this process and thus increase the likelihood that their discoveries will be successfully commercialized. I also hope that this report will assist such researchers to understand the policy and institutional considerations that underlie current debates concerning technology transfer.

    2013-01-01

    Non-human animals have starred in countless productions of biological research. Whether they play the lead or supporting role depends on the nature of the investigation. These differences in the roles of animals affect nearly every facet of animal involvement, including: the choice of species, the sample size, the source of individuals, and the settings in which the animals are used. These roles establish different baselines for animal use that require substantially different ethical considerations. Efficient and appropriate oversight of wildlife research benefits the animals and their investigators. Toward that end, Institutional Animal Care and Use Committee (IACUCs) must appreciate the profound differences between biomedical and wildlife research and recognize the value of the state and federal permitting processes required for wildlife studies. These processes assure us that potential impacts beyond the level of the individual are minimal or are justified. Most importantly, IACUCs must recognize that they, and their investigators, have an obligation to use appropriate guidelines for evaluating wildlife research.

In 2011, the Council for Science and Technology Policy released the 4th Japan's Science and Technology Basic Policy Report from 2011 to 2015. This report includes two major innovations, 'Life Innovation' and 'Green Innovation', to promote economic growth. Biomedical engineering research is part of 'Life Innovation' and its outcomes are required to maintain people's mental and physical health. It has already resulted in numerous biomedical products, and new ones should be developed using nanotechnology-based concepts. The combination of accumulated knowledge and experience, and 'nanoarchitechtonics' will result in novel, well-designed functional biomaterials. This focus issue contains three reviews and 19 original papers on various biomedical topics, including biomaterials, drug-delivery systems, tissue engineering and diagnostics. We hope that it demonstrates the importance of collaboration among scientists, engineers and clinicians, and will contribute to the further development of biomedical engineering.

  13. Commercializing biomedical research through securitization techniques.

    PubMed

    Fernandez, Jose-Maria; Stein, Roger M; Lo, Andrew W

    2012-10-01

    Biomedical innovation has become riskier, more expensive and more difficult to finance with traditional sources such as private and public equity. Here we propose a financial structure in which a large number of biomedical programs at various stages of development are funded by a single entity to substantially reduce the portfolio's risk. The portfolio entity can finance its activities by issuing debt, a critical advantage because a much larger pool of capital is available for investment in debt versus equity. By employing financial engineering techniques such as securitization, it can raise even greater amounts of more-patient capital. In a simulation using historical data for new molecular entities in oncology from 1990 to 2011, we find that megafunds of $5–15 billion may yield average investment returns of 8.9–11.4% for equity holders and 5–8% for 'research-backed obligation' holders, which are lower than typical venture-capital hurdle rates but attractive to pension funds, insurance companies and other large institutional investors.

    We have developed state-of-the-art nanomaterials such as nanofibers, nanotubes, nanoparticles, nanocatalysts and nanostructures for clean energy, environmental and biomedical research. Energy can neither be created nor be destroyed, but it can be converted from one form to another. Based on this principle, chemical energy such as hydrogen has been produced from water electrolysis at a much lower voltage using RuO{sub 2} nanoparticles on the Si wafer substrate. Once the hydrogen is produced from the clean sources such as solar energy and water, it has to be stored by physisorption or chemisorption processes on to the solid state systems. For the successful physical adsorption of hydrogen molecule, we have developed novel polyaniline nanostructures via chemical templating and electrospinning routes. Chemical or complex hydrides involving nano MgH{sub 2} and transition metal nanocatalysts have been synthesized to tailor both the thermodynamics and kinetics of hydrogen (chemi) sorption respectively. Utilization of solar energy (UV-Vis) and a coupling of novel semiconductor oxide nanoparticles have been recently demonstrated with enhancement in photo-oxidation and/or photo-reduction processes for the water/air detoxification and sustainable liquid fuel production respectively. Magnetic nanoparticles such as ZnFe{sub 2}O{sub 4} have been synthesized and optimized for biomedical applications such as targeted drug delivery and tumor diagnostic sensing (MRI)

  16. [Biomedical research from philanthropy to scarcity.

    Addis, Antonio; De Fiore, Luca; Traversa, Giuseppe

    2016-10-01

    Some huge information technology companies have increased investment in biomedical research: recently Google, Microsoft, and Facebook. The latter presented the ambitious Zuckerberg-Chan Initiative involving three major Californian universities: UC San Francisco, Berkeley and Stanford. These important private investments arouse reflections. First, investing in scientific research improves the corporate image of the most generous companies and it is a great marketing strategy. Second, the availability of private funds is surely useful, especially if these funds are directed to relevant projects, and produce studies conducted and disseminated in a transparent way. Third, private funding should not replace public ones, representing an integration that will not likely affect the determination of the research agenda, which should remain the prerogative of public institutions. Fourth, the researchers involved in public funded projects should benefit from the margin of freedom that private industry promises, both in the decision of research pathways and in their course. Finally, the scarcity of resources is likely to divert energy and attention of the public researchers and this aspect should be considered by decision makers when determining size and recipients of research funding.

  17. The diversity of experimental organisms in biomedical research may be influenced by biomedical funding.

    Contrary to concerns of some critics, we present evidence that biomedical research is not dominated by a small handful of model organisms. An exhaustive analysis of research literature suggests that the diversity of experimental organisms in biomedical research has increased substantially since 1975. There has been a longstanding worry that organism-centric funding policies can lead to biases in experimental organism choice, and thus negatively impact the direction of research and the interpretation of results. Critics have argued that a focus on model organisms has unduly constrained the diversity of experimental organisms. The availability of large electronic databases of scientific literature, combined with interest in quantitative methods among philosophers of science, presents new opportunities for data-driven investigations into organism choice in biomedical research. The diversity of organisms used in NIH-funded research may be considerably lower than in the broader biomedical sciences, and may be subject to greater constraints on organism choice.

    2015-01-01

    Carbohydrates constitute the most abundant organic matter in nature, serving as structural components and energy sources, and mediating a wide range of cellular activities. The emergence of nanomaterials with distinct optical, magnetic, and electronic properties has witnessed a rapid adoption of these materials for biomedical research and applications. Nanomaterials of various shapes and sizes having large specific surface areas can be used as multivalent scaffolds to present carbohydrate ligands. The resulting glyconanomaterials effectively amplify the glycan-mediated interactions, making it possible to use these materials for sensing, imaging, diagnosis, and therapy. In this review, we summarize the synthetic strategies for the preparation of various glyconanomaterials. Examples are given where these glyconanomaterials have been used in sensing and differentiation of proteins and cells, as well as in imaging glycan-medicated cellular responses. PMID:26500721

    Objective As biomedical technology becomes increasingly sophisticated, researchers can probe ever more subtle effects with the added requirement that the investigation of small effects often requires the acquisition of large amounts of data. In biomedicine, these data are often acquired at, and later shared between, multiple sites. There are both technological and sociological hurdles to be overcome for data to be passed between researchers and later made accessible to the larger scientific community. The goal of the Biomedical Informatics Research Network (BIRN) is to address the challenges inherent in biomedical data sharing. Materials and methods BIRN tools are grouped into ‘capabilities’ and are available in the areas of data management, data security, information integration, and knowledge engineering. BIRN has a user-driven focus and employs a layered architectural approach that promotes reuse of infrastructure. BIRN tools are designed to be modular and therefore can work with pre-existing tools. BIRN users can choose the capabilities most useful for their application, while not having to ensure that their project conforms to a monolithic architecture. Results BIRN has implemented a new software-based data-sharing infrastructure that has been put to use in many different domains within biomedicine. BIRN is actively involved in outreach to the broader biomedical community to form working partnerships. Conclusion BIRN's mission is to provide capabilities and services related to data sharing to the biomedical research community. It does this by forming partnerships and solving specific, user-driven problems whose solutions are then available for use by other groups. PMID:21515543

    This report summarizes presentations and discussions at an NIH-sponsored workshop on Neotropical Primates in Biomedical Research, held in September 2010. Neotropical primates (New World monkeys), with their smaller size, faster maturation, and shorter lifespans than Old World monkeys, are efficient models and present unique opportunities for studying human health and disease. After overviews of the most commonly used neotropical species-squirrel monkeys, marmosets, and owl monkeys-speakers described the use of neotropical primates in specific areas of immunology, infectious disease, neuroscience, and physiology research. Presentations addressed the development of new research tools: immune-based reagents, fMRI technologies suited to these small primates, sequencing of the marmoset genome, the first germline transgenic monkey, and neotropical primate induced pluripotent stem cells. In the discussions after the presentations, participants identified challenges to both continued use and development of new uses of neotropical primates in research and suggested the following actions to address the challenges: (1) mechanisms to support breeding colonies of some neotropical species to ensure a well-characterized domestic source; (2) resources for the continuing development of critical research tools to improve the immunological and hormonal characterization of neotropical primates; (3) improved opportunities for networking among investigators who use neotropical primates, training and other measures to improve colony and veterinary management, and continued research on neotropical primate management and veterinary care issues; (4) support for development activities to produce models that are more affordable and more efficient for moving research "from benchside to bedside"; and (5) establishment of a small program that would fund "orphan" species.

    Summary Background Medical informatics, or biomedical and health informatics (BMHI), has become an established scientific discipline. In all such disciplines there is a certain inertia to persist in focusing on well-established research areas and to hold on to well-known research methodologies rather than adopting new ones, which may be more appropriate. Objectives To search for answers to the following questions: What are research fields in informatics, which are not being currently adequately addressed, and which methodological approaches might be insufficiently used? Do we know about reasons? What could be consequences of change for research and for education? Methods Outstanding informatics scientists were invited to three panel sessions on this topic in leading international conferences (MIE 2015, Medinfo 2015, HEC 2016) in order to get their answers to these questions. Results A variety of themes emerged in the set of answers provided by the panellists. Some panellists took the theoretical foundations of the field for granted, while several questioned whether the field was actually grounded in a strong theoretical foundation. Panellists proposed a range of suggestions for new or improved approaches, methodologies, and techniques to enhance the BMHI research agenda. Conclusions The field of BMHI is on the one hand maturing as an academic community and intellectual endeavour. On the other hand vendor-supplied solutions may be too readily and uncritically accepted in health care practice. There is a high chance that BMHI will continue to flourish as an important discipline; its innovative interventions might then reach the original objectives of advancing science and improving health care outcomes.

    Medical Sciences Research Building III (MSRB III) is a 10-story, 207,000 ft{sup 2} (19,230 m{sup 2}) biomedical research facility on the campus of the University of Michigan. The design of MSRB III required a variety of technological solutions to complex design issues. The systems also had to accommodate future modifications. Closely integrated, modular systems with a high degree of flexibility were designed to respond to this requirement. Additionally, designs were kept as simple as possible for operation and maintenance personnel. Integrated electronic controls were used to provide vital data during troubleshooting and maintenance procedures. Equipment was also specified that provides reliability and minimizes maintenance. Other features include 100% redundancy of all central equipment servicing the animal housing area; redundant temperature controls for each individual animal housing room for fail-safe operation to protect the animals against overheating; and accessibility to all items requiring maintenance through an above-ceiling coordination process. It is critical that the engineering systems for MSRB III provide a safe, comfortable, energy efficient environment. The achievement of this design intent was noted by the University`s Commissioning Review Committee which stated: The Commissioning Process performed during both the design phase and construction phase of MSRB III was a significant success, providing an efficiently functioning facility that has been built in accordance with its design intent.

    2016-01-01

    Domestic animals are unique models for biomedical research due to their long history (thousands of years) of strong phenotypic selection. This process has enriched for novel mutations that have contributed to phenotype evolution in domestic animals. The characterization of such mutations provides insights in gene function and biological mechanisms. This review summarizes genetic dissection of about 50 genetic variants affecting pigmentation, behaviour, metabolic regulation, and the pattern of locomotion. The variants are controlled by mutations in about 30 different genes, and for 10 of these our group was the first to report an association between the gene and a phenotype. Almost half of the reported mutations occur in non-coding sequences, suggesting that this is the most common type of polymorphism underlying phenotypic variation since this is a biased list where the proportion of coding mutations are inflated as they are easier to find. The review documents that structural changes (duplications, deletions, and inversions) have contributed significantly to the evolution of phenotypic diversity in domestic animals. Finally, we describe five examples of evolution of alleles, which means that alleles have evolved by the accumulation of several consecutive mutations affecting the function of the same gene.

    Lambrecht, R. M.

    The current and projected annual requirements through 1985 for stable isotopes enriched by electromagnetic separation methods were reviewed for applications in various types of biomedical research: (1) medical radiosiotope production, labeled compounds, and potential radio-pharmaceuticals; (2) nutrition, food science, and pharmacology: (3) metallobiochemistry and environmental toxicology; (4) nuclear magnetic resonance, electron paramagnetic resonance, and moessbauer spectroscopy in biochemical, biophysical, and biomedical research; and (5) miscellaneous advances in radioactive and nonradioactive tracer technology. Radioisotopes available from commercial sources or routinely used in clinical nuclear medicine were excluded. Current requirements for enriched stable isotopes in biomedical research are not being satisfied. Severe shortages exist for Mg 26, Ca 43, Zn 70, Se 76, Se 77, Se 78, Pd 102, Cd 111, Cd 113, and Os 190. Many interesting and potentially important investigations in biomedical research require small quantities of specific elements at high isotopic enrichments.

    Electronic health records (EHR) are a vital data resource for research uses, including cohort identification, phenotyping, pharmacovigilance, and public health surveillance. To realize the promise of EHR data for accelerating clinical research, it is imperative to enable efficient and autonomous EHR data interrogation by end users such as biomedical researchers. This paper surveys state-of-art approaches and key methodological considerations to this purpose. We adapted a previously published conceptual framework for interactive information retrieval, which defines three entities: user, channel, and source, by elaborating on channels for query formulation in the context of facilitating end users to interrogate EHR data. We show the current progress in biomedical informatics mainly lies in support for query execution and information modeling, primarily due to emphases on infrastructure development for data integration and data access via self-service query tools, but has neglected user support needed during iteratively query formulation processes, which can be costly and error-prone. In contrast, the information science literature has offered elaborate theories and methods for user modeling and query formulation support. The two bodies of literature are complementary, implying opportunities for cross-disciplinary idea exchange. On this basis, we outline the directions for future informatics research to improve our understanding of user needs and requirements for facilitating autonomous interrogation of EHR data by biomedical researchers. We suggest that cross-disciplinary translational research between biomedical informatics and information science can benefit our research in facilitating efficient data access in life sciences.

Several codes and instruments have been formulated to regulate biomedical research. In Kenya, the Science, Technology and Innovation Act, 2014, together with the Constitution of Kenya, 2010, provide a fairly robust legal framework. Possible challenges include capacity building, overlap of functions of institutions, monitoring and evaluation, scientific/technological advances, intellectual property rights, funding for research, and dispute resolution. It is hoped that the new legislation will adequately address these challenges.

    The development of a piezo-resistive pressure transducer is discussed suitable for recording pressures typically encountered in biomedical applications. The pressure transducer consists of a thin silicon diaphragm containing four strain-sensitive resistors, and is fabricated using silicon monolithic integrated-circuit technology. The pressure transducers can be as small as 0.7 mm outer diameter, and are, as a result, suitable for mounting at the tip of a catheter. Pressure-induced stress in the diaphragm is sensed by the resistors, which are interconnected to form a Wheatstone bridge.

  5. Diversity in the biomedical research workforce: developing talent.

    PubMed

    McGee, Richard; Saran, Suman; Krulwich, Terry A

    2012-01-01

    Much has been written about the need for and barriers to achievement of greater diversity in the biomedical workforce from the perspectives of gender, race, and ethnicity; this is not a new topic. These discussions often center around a "pipeline" metaphor that imagines students flowing through a series of experiences to eventually arrive at a science career. Here we argue that diversity will only be achieved if the primary focus is on (1) what is happening within the pipeline, not just counting individuals entering and leaving it; (2) de-emphasizing the achievement of academic milestones by typical ages; and (3) adopting approaches that most effectively develop talent. Students may develop skills at different rates based on factors such as earlier access to educational resources, exposure to science (especially research experiences), and competing demands for time and attention during high school and college. Therefore, there is wide variety among students at any point along the pipeline. Taking this view requires letting go of imagining the pipeline as a sequence of age-dependent steps in favor of milestones of skill and talent development decoupled from age or educational stage. Emphasizing talent development opens up many new approaches for science training outside of traditional degree programs. This article provides examples of such approaches, including interventions at the postbaccalaureate and PhD levels, as well as a novel coaching model that incorporates well-established social science theories and complements traditional mentoring. These approaches could significantly impact diversity by developing scientific talent, especially among currently underrepresented minorities.

    Simple Summary This article reviews the use of non-human animals in biomedical research from a historical viewpoint, providing an insight into the most relevant social and moral issues on this topic across time, as well as to how the current paradigm for ethically and publically acceptable use of animals in biomedicine has been achieved. Abstract The use of non-human animals in biomedical research has given important contributions to the medical progress achieved in our day, but it has also been a cause of heated public, scientific and philosophical discussion for hundreds of years. This review, with a mainly European outlook, addresses the history of animal use in biomedical research, some of its main protagonists and antagonists, and its effect on society from Antiquity to the present day, while providing a historical context with which to understand how we have arrived at the current paradigm regarding the ethical treatment of animals in research.

  7. A framework for risk-benefit evaluations in biomedical research.

    PubMed

    Rid, Annette; Wendler, David

    2011-06-01

    Essentially all guidelines and regulations require that biomedical research studies have an acceptable risk-benefit profile. However, these documents offer little concrete guidance for implementing this requirement and determining when it is satisfied. As a result, those charged with risk-benefit evaluations currently assess the risk-benefit profile of biomedical research studies in unsystematic ways, raising concern that some research participants are not being protected from excessive risks and that some valuable studies involving acceptable risk are being rejected. The present paper aims to address this situation by delineating the first comprehensive framework, which is based on existing guidelines and regulations as well as the relevant literature, for risk-benefit evaluations in biomedical research.

    Decades of costly failures in translating drug candidates from preclinical disease models to human therapeutic use warrant reconsideration of the priority placed on animal models in biomedical research. Following an international workshop attended by experts from academia, government institutions, research funding bodies and the corporate and NGO sectors, this consensus report analyses, as case studies, five disease areas with major unmet needs for new treatments. In view of the scientifically driven transition towards a human pathways-based paradigm in toxicology, a similar paradigm shift appears to be justified in biomedical research. There is a pressing need for an approach that strategically implements advanced, human biology-based models and tools to understand disease pathways at multiple biological scales. We present recommendations to help achieve this. To discover and develop new therapies, we need 21-century roadmaps for biomedical research based on multiscale human disease pathways, and supported by policy and funding strategies that prioritise human relevance.

  9. Animal Experiments in Biomedical Research: A Historical Perspective.

    Franco, Nuno Henrique

    2013-03-19

    The use of non-human animals in biomedical research has given important contributions to the medical progress achieved in our day, but it has also been a cause of heated public, scientific and philosophical discussion for hundreds of years. This review, with a mainly European outlook, addresses the history of animal use in biomedical research, some of its main protagonists and antagonists, and its effect on society from Antiquity to the present day, while providing a historical context with which to understand how we have arrived at the current paradigm regarding the ethical treatment of animals in research.

  10. Cruel knives? Vivisection and biomedical research in Victorian English Canada.

    PubMed

    Connor, J T

    1997-01-01

    This discussion shows how the use of animals in biomedical research in Canada evolved during the latter half of the nineteenth century from simple demonstrations to more sophisticated series of experiments. More important, however, is the argument advanced that Anglo-Canadian society's response to vivisection and the use of animals in research centred on issues such as cruelty, exploitation, and broader notions of religion, power, and gender. This exploration of vivisection in Victorian Canada, then, reveals that it was, as elsewhere, a complex debate involving more than the use of animals for biomedical research purposes.

    Integrative biomedical research projects query, analyze, and integrate many different data types and make use of datasets obtained from measurements or simulations of structure and function at multiple biological scales. With the increasing availability of high-throughput and high-resolution instruments, the integrative biomedical research imposes many challenging requirements on software middleware systems. In this paper, we look at some of these requirements using example research pattern templates. We then discuss how middleware systems, which incorporate Grid and high-performance computing, could be employed to address the requirements. PMID:20107625

    Livestock models have contributed significantly to biomedical and surgical advances. Their contribution is particularly prominent in the areas of physiology and assisted reproductive technologies, including understanding developmental processes and disorders, from ancient to modern times. Over the past 25 years, biomedical research that traditionally embraced a diverse species approach shifted to a small number of model species (e.g. mice and rats). The initial reasons for focusing the main efforts on the mouse were the availability of murine embryonic stem cells (ESCs) and genome sequence data. This powerful combination allowed for precise manipulation of the mouse genome (knockouts, knockins, transcriptional switches etc.) leading to ground-breaking discoveries on gene functions and regulation, and their role in health and disease. Despite the enormous contribution to biomedical research, mouse models have some major limitations. Their substantial differences compared with humans in body and organ size, lifespan and inbreeding result in pronounced metabolic, physiological and behavioural differences. Comparative studies of strategically chosen domestic species can complement mouse research and yield more rigorous findings. Because genome sequence and gene manipulation tools are now available for farm animals (cattle, pigs, sheep and goats), a larger number of livestock genetically engineered (GE) models will be accessible for biomedical research. This paper discusses the use of cattle, goats, sheep and pigs in biomedical research, provides an overview of transgenic technology in farm animals and highlights some of the beneficial characteristics of large animal models of human disease compared with the mouse. In addition, status and origin of current regulation of GE biomedical models is also reviewed.

  16. Trust me, I'm a researcher!: The role of trust in biomedical research.

    PubMed

    Kerasidou, Angeliki

    2017-03-01

    In biomedical research lack of trust is seen as a great threat that can severely jeopardise the whole biomedical research enterprise. Practices, such as informed consent, and also the administrative and regulatory oversight of research in the form of research ethics committees and Institutional Review Boards, are established to ensure the protection of future research subjects and, at the same time, restore public trust in biomedical research. Empirical research also testifies to the role of trust as one of the decisive factors in research participation and lack of trust as a barrier for consenting to research. However, what is often missing is a clear definition of trust. This paper seeks to address this gap. It starts with a conceptual analysis of the term trust. It compares trust with two other related terms, those of reliance and trustworthiness, and offers a defence of Baier's attribute of 'good will' a basic characteristic of trust. It, then, proceeds to consider trust in the context of biomedical research by examining two questions: First, is trust necessary in biomedical research?; and second, do increases in regulatory oversight of biomedical research also increase trust in the field? This paper argues that regulatory oversight is important for increasing reliance in biomedical research, but it does not improve trust, which remains important for biomedical research. It finishes by pointing at professional integrity as a way of promoting trust and trustworthiness in this field.

    2001-12-01

    To date, biomedical research using nominal data files for the data collection, data acquisition or data processing has had to comply with 2 French laws (Law of December, 20, 1988, modified, relating to the protection of patients participating in biomedical research, and the Law of January, 6, 1978, completed by the Law of July 1, 1994 n degrees 94-548, chapter V bis). This later law dictates rules not only for the establishment of nominal data files, but also confer individual rights to filed persons. These regulations concern epidemiological research, clinical trials, drug watch studies and economic health research. In this note, we describe the obligations and specific general and simplified procedure required for conducting biomedical research. Included in the requirements are an information and authorization procedure with the local and national consultative committees on data processing in biomedical research (CCTIRS, Comité Consultatif sur le Traitement de l'Information en Recherche Biomédicale, and CNIL, Commission Nationale Informatique et Libertés).

    Several committees were established by the National Association of Physicians for the Environment to investigate and report on various topics at the National Leadership Conference on Biomedical Research and the Environment held at the 1--2 November 1999 at the National Institutes of Health in Bethesda, Maryland. This is the report of the Committee on Minimization and Management of Wastes from Biomedical Research. Biomedical research facilities contribute a small fraction of the total amount of wastes generated in the United States, and the rate of generation appears to be decreasing. Significant reductions in generation of hazardous, radioactive, and mixed wastes have recently been reported, even at facilities with rapidly expanding research programs. Changes in the focus of research, improvements in laboratory techniques, and greater emphasis on waste minimization (volume and toxicity reduction) explain the declining trend in generation. The potential for uncontrolled releases of wastes from biomedical research facilities and adverse impacts on the general environment from these wastes appears to be low. Wastes are subject to numerous regulatory requirements and are contained and managed in a manner protective of the environment. Most biohazardous agents, chemicals, and radionuclides that find significant use in research are not likely to be persistent, bioaccumulative, or toxic if they are released. Today, the primary motivations for the ongoing efforts by facilities to improve minimization and management of wastes are regulatory compliance and avoidance of the high disposal costs and liabilities associated with generation of regulated wastes. The committee concluded that there was no evidence suggesting that the anticipated increases in biomedical research will significantly increase generation of hazardous wastes or have adverse impacts on the general environment. This conclusion assumes the positive, countervailing trends of enhanced pollution prevention

  20. SEACOIN--an investigative tool for biomedical informatics researchers.

    PubMed

    Lee, Eva K; Lee, Hee-Rin; Quarshie, Alexander

    2011-01-01

    Peer-reviewed scientific literature is a prime source for accessing knowledge in the biomedical field. Its rapid growth and diverse domain coverage require systematic efforts in developing interactive tools for efficiently searching and summarizing current advances for acquiring knowledge and referencing, and for furthering scientific discovery. Although information retrieval systems exist, the conventional tools and systems remain difficult for biomedical investigators to use. There remain gaps even in the state-of-the-art systems as little attention has been devoted to understanding the needs of biomedical researchers. Our work attempts to bridge the gap between the needs of biomedical users and systems design efforts. We first study the needs of users and then design a simple visual analytic application tool, SEACOIN. A key motivation stems from biomedical researchers' request for a "simple interface" that is suitable for novice users in information technology. The system minimizes information overload, and allows users to search easily even in time-constrained situations. Users can manipulate the depth of information according to the purpose of usage. SEACOIN enables interactive exploration and filtering of search results via "metamorphose topological visualization" and "tag cloud," visualization tools that are commonly used in social network sites. We illustrate SEACOIN's usage through applications on PubMed publications on heart disease, cancer, Alzheimer's disease, diabetes, and asthma.

    Strategies for protecting historically disadvantaged groups have been extensively debated in the context of genetic variation research, making this a useful starting point in examining the protection of social groups from harm resulting from biomedical research. We analyze research practices developed in response to concerns about the involvement of indigenous communities in studies of genetic variation and consider their potential application in other contexts. We highlight several conceptual ambiguities and practical challenges associated with the protection of group interests and argue that protectionist strategies developed in the context of genetic research will not be easily adapted to other types of research in which social groups are placed at risk. We suggest that it is this set of conceptual and practical issues that philosophers, ethicists, and others should focus on in their efforts to protect identifiable social groups from harm resulting from biomedical research.

    The long-held but erroneous assumption of never-ending rapid growth in biomedical science has created an unsustainable hypercompetitive system that is discouraging even the most outstanding prospective students from entering our profession—and making it difficult for seasoned investigators to produce their best work. This is a recipe for long-term decline, and the problems cannot be solved with simplistic approaches. Instead, it is time to confront the dangers at hand and rethink some fundamental features of the US biomedical research ecosystem. PMID:24733905

    Context With the exception of the American Recovery and Reinvestment Act, funding support for biomedical research in the United States has slowed after a decade of doubling. However, the extent and scope of slowing are largely unknown. Objective To quantify funding of biomedical research in the United States from 2003 to 2008. Design We used publicly available data to quantify funding from federal, state and local government, private, and industry sources. We used regression models to compare financial trends between 1994–2003 and 2003–2007 (the last year complete data were available). We also evaluated the number of new drug and device approvals by the US Food and Drug Administration (FDA) over the same time period. Main Outcome Measures Funding and growth rates by source. Number of FDA approvals. Results Biomedical research funding increased from $75.5 billion in 2003 to $101.1 billion in 2007. In 2008 funding from the National Institutes of Health (NIH) and industry totaled $88.8 billion. In 2007 funding from these sources, adjusted for inflation, was $90.2 billion. Adjusted for inflation, funding from 2003 to 2007 increased by 14% for a compound annual growth rate of 3.4%. By comparison, funding from 1994 to 2003 increased at an annual rate of 7.8% (P<0.001). In 2007, industry (58%) was the largest funder followed by the federal government (33%). The modest increase in funding was not accompanied by an increase in approvals for drugs or devices. In 2007 the United States spent an estimated 4.5% of its total health expenditures on biomedical research and 0.1% on health services research. Conclusions After a decade of doubling, the rate of increase in biomedical research funding slowed from 2003 to 2007, and after adjusting for inflation, the absolute level of funding from NIH and industry appears to have decreased by 2% in 2008.

    The health and well-being of all individuals, independent of race, ethnicity, or gender, is a significant public health concern. Despite many improvements in the status of minority health, African American males continue to have the highest age-adjusted mortality rate of any race-sex group in the United States. Such disparities are accounted for by deaths from a number of diseases such as diabetes, human immunodeficiency virus (HIV), cancer, and cardiovascular disease, as well as by many historical and present social and cultural constructs that present as obstacles to better health outcomes. Distrust of the medical community, inadequate education, low socioeconomic status, social deprivation, and underutilized primary health care services all contribute to disproportionate health and health care outcomes among African Americans compared to their Caucasian counterparts. Results of clinical research on diseases that disproportionately affect African American males are often limited in their reliability due to common sampling errors existing in the majority of biomedical research studies and clinical trials. There are many reasons for underrepresentation of African American males in clinical trials, including their common recollection and interpretation of relevant historical of biomedical events where minorities were abused or exposed to racial discrimination or racist provocation. In addition, African American males continue to be less educated and more disenfranchised from the majority in society than Caucasian males and females and their African American female counterparts. As such, understanding their perceptions, even in early developmental years, about health and obstacles to involvement in research is important. In an effort to understand perspectives about their level of participation, motivation for participation, impact of education, and engagement in research, this study was designed to explore factors that impact their willingness to participate.

    McGee, Richard; Saran, Suman; Krulwich, Terry A.

    2012-01-01

    Much has been written about the need for and barriers to achievement of greater diversity in the biomedical workforce from the perspectives of gender, race and ethnicity; this is not a new topic. These discussions often center around a ‘pipeline metaphor’ which imagines students flowing through a series of experiences to eventually arrive at a science career. Here we argue that diversity will only be achieved if the primary focus is on: what is happening within the pipeline, not just counting individuals entering and leaving it; de-emphasizing achieving academic milestones by ‘typical’ ages; and adopting approaches that most effectively develop talent. Students may develop skills at different rates based on factors such as earlier access to educational resources, exposure to science (especially research experiences), and competing demands for time and attention during high school and college. Therefore, there is wide variety among students at any point along the pipeline. Taking this view requires letting go of imagining the pipeline as a sequence of age-dependent steps in favor of milestones of skill and talent development decoupled from age or educational stage. Emphasizing talent development opens up many new approaches for science training outside of traditional degree programs. This article provides examples of such approaches, including interventions at the post-baccalaureate and PhD levels, as well as a novel coaching model that incorporates well-established social science theories and complements traditional mentoring. These approaches could significantly impact diversity by developing scientific talent, especially among currently underrepresented minorities. PMID:22678863

    2013-09-01

    Search for specific and well defined literature related to subject of interest is the foremost step in research. When we are familiar with topic or subject then we can frame appropriate research question. Appropriate research question is the basis for study objectives and hypothesis. The Internet provides a quick access to an overabundance of the medical literature, in the form of primary, secondary and tertiary literature. It is accessible through journals, databases, dictionaries, textbooks, indexes, and e-journals, thereby allowing access to more varied, individualised, and systematic educational opportunities. Web search engine is a tool designed to search for information on the World Wide Web, which may be in the form of web pages, images, information, and other types of files. Search engines for internet-based search of medical literature include Google, Google scholar, Scirus, Yahoo search engine, etc., and databases include MEDLINE, PubMed, MEDLARS, etc. Several web-libraries (National library Medicine, Cochrane, Web of Science, Medical matrix, Emory libraries) have been developed as meta-sites, providing useful links to health resources globally. A researcher must keep in mind the strengths and limitations of a particular search engine/database while searching for a particular type of data. Knowledge about types of literature, levels of evidence, and detail about features of search engine as available, user interface, ease of access, reputable content, and period of time covered allow their optimal use and maximal utility in the field of medicine. Literature search is a dynamic and interactive process; there is no one way to conduct a search and there are many variables involved. It is suggested that a systematic search of literature that uses available electronic resource effectively, is more likely to produce quality research.

    Cancer is a malignant disease that has caused millions of human deaths. Its study has a long history of well over 100years. There have been an enormous number of publications on cancer research. This integrated but unstructured biomedical text is of great value for cancer diagnostics, treatment, and prevention. The immense body and rapid growth of biomedical text on cancer has led to the appearance of a large number of text mining techniques aimed at extracting novel knowledge from scientific text. Biomedical text mining on cancer research is computationally automatic and high-throughput in nature. However, it is error-prone due to the complexity of natural language processing. In this review, we introduce the basic concepts underlying text mining and examine some frequently used algorithms, tools, and data sets, as well as assessing how much these algorithms have been utilized. We then discuss the current state-of-the-art text mining applications in cancer research and we also provide some resources for cancer text mining. With the development of systems biology, researchers tend to understand complex biomedical systems from a systems biology viewpoint. Thus, the full utilization of text mining to facilitate cancer systems biology research is fast becoming a major concern. To address this issue, we describe the general workflow of text mining in cancer systems biology and each phase of the workflow. We hope that this review can (i) provide a useful overview of the current work of this field; (ii) help researchers to choose text mining tools and datasets; and (iii) highlight how to apply text mining to assist cancer systems biology research.

  19. Reengineering Biomedical Translational Research with Engineering Ethics.

    2015-08-01

    It is widely accepted that translational research practitioners need to acquire special skills and knowledge that will enable them to anticipate, analyze, and manage a range of ethical issues. While there is a small but growing literature that addresses the ethics of translational research, there is a dearth of scholarship regarding how this might apply to engineers. In this paper we examine engineers as key translators and argue that they are well positioned to ask transformative ethical questions. Asking engineers to both broaden and deepen their consideration of ethics in their work, however, requires a shift in the way ethics is often portrayed and perceived in science and engineering communities. Rather than interpreting ethics as a roadblock to the success of translational research, we suggest that engineers should be encouraged to ask questions about the socio-ethical dimensions of their work. This requires expanding the conceptual framework of engineering beyond its traditional focus on "how" and "what" questions to also include "why" and "who" questions to facilitate the gathering of normative, socially-situated information. Empowering engineers to ask "why" and "who" questions should spur the development of technologies and practices that contribute to improving health outcomes.

  20. THE CONCEPT OF RISK IN BIOMEDICAL RESEARCH INVOLVING HUMAN SUBJECTS

    PubMed Central

    VAN NESS, PETER H.

    2015-01-01

    An established ethical principle of biomedical research involving human subjects stipulates that risk to subjects should be proportionate to an experiment’s potential benefits. Sometimes this principle is imprecisely stated as a requirement that ‘risks and benefits’ be balanced. First, it is noted why this language is imprecise. Second, the persistence of such language is attributed to how it functions as a rhetorical trope. Finally, an argument is made that such a trope is infelicitous because it may not achieve its intended persuasive purposes. More importantly, it should be avoided because it masks the important role that chance plays in clinical research. Risk is the possibility of harm. As a precondition of harm it is unintended and undesirable in projects of biomedical research. It requires ethical vigilance. As a vehicle of chance, however, it is both intended and desirable. It requires methodological appreciation. PMID:11697390

    Research activities on a comprehensive multidisciplinary program are vital for enhancement of the system of crew's medical care, environmental health and hygiene in space missions. The primary goal of the program must be identification of patterns, intensity and dynamics of structural and functional shifts in organism induced by an aggregate of spaceflight factors including microgravity, isolation, artificial environment, space radiation, etc. Also, the program must pursue differential assessment of emerging deviations from the standpoint of adequacy to the spaceflight conditions and prospects of returning to Earth and guide the development of principles, methods and techniques necessary to maintain health and working capacity of humans during short- and long-duration missions and on return to Earth. Over 50 years, since 1963, the IBMP researchers apply systemic and innovational approaches to fundamental and exploratory studies in the fields of medical sciences, radiation biology, engineering science, biotechnology, etc. with participation of various biological specimens and human volunteers. Investigations aboard manned spacecrafts and biological satellites as well as in ground-based laboratories further enhancement of the medical care system for crews on orbital and remote space missions; they give insight into the fundamental problems of gravitational physiology and biology, psychophysiology, radiation biology, and contribute thereby to the development of knowledge, methods and technologies, as well as medical and scientific equipment.

  5. Limits on risks for healthy volunteers in biomedical research.

    PubMed

    Resnik, David B

    2012-04-01

    Healthy volunteers in biomedical research often face significant risks in studies that offer them no medical benefits. The U.S. federal research regulations and laws adopted by other countries place no limits on the risks that these participants face. In this essay, I argue that there should be some limits on the risks for biomedical research involving healthy volunteers. Limits on risk are necessary to protect human participants, institutions, and the scientific community from harm. With the exception of self-experimentation, limits on research risks faced by healthy volunteers constitute a type of soft, impure paternalism because participants usually do not fully understand the risks they are taking. I consider some approaches to limiting research risks and propose that healthy volunteers in biomedical research should not be exposed to greater than a 1% chance of serious harm, such as death, permanent disability, or severe illness or injury. While this guideline would restrict research risks, the limits would not be so low that they would prevent investigators from conducting valuable research. They would, however, set a clear upper boundary for investigators and signal to the scientific community and the public that there are limits on the risks that healthy participants may face in research. This standard provides guidance for decisions made by oversight bodies, but it is not an absolute rule. Investigators can enroll healthy volunteers in studies involving a greater than 1% chance of serious harm if they show that the research addresses a compelling public health or social problem and that the risk of serious harm is only slightly more than 1%. The committee reviewing the research should use outside experts to assess these risks.

    Background Medical research productivity reflects the level of medical education and practice in a particular country. The objective of this study was to examine the quantity and quality of medical and biomedical research published from Palestine. Findings Comprehensive review of the literature indexed by Scopus was conducted. Data from Jan 01, 2002 till December 31, 2011 was searched for authors affiliated with Palestine or Palestinian authority. Results were refined to limit the search to medical and biomedical subjects. The quality of publication was assessed using Journal Citation Report. The total number of publications was 2207. A total of 770 publications were in the medical and biomedical subject areas. The annual rate of publication was 0.077 articles per gross domestic product/capita. The 770 publications have an h-index of 32. One hundred and thirty eight (18%) articles were published in 46 journals that were not indexed in the web of knowledge. Twenty two (22/770; 2.9%) articles were published in journals with an IF > 10. Conclusions The quantity and quality of research originating from Palestinian institutions is promising given the scarce resources of Palestine. However, more effort is needed to bridge the gap in medical research productivity and to promote better health in Palestine. PMID:23375070

  9. Race in Biological and Biomedical Research

    PubMed Central

    Cooper, Richard S.

    2013-01-01

    The concept of race has had a significant influence on research in human biology since the early 19th century. But race was given its meaning and social impact in the political sphere and subsequently intervened in science as a foreign concept, not grounded in the dominant empiricism of modern biology. The uses of race in science were therefore often disruptive and controversial; at times, science had to be retrofitted to accommodate race, and science in turn was often used to explain and justify race. This relationship was unstable in large part because race was about a phenomenon that could not be observed directly, being based on claims about the structure and function of genomic DNA. Over time, this relationship has been characterized by distinct phases, evolving from the inference of genetic effects based on the observed phenotype to the measurement of base-pair variation in DNA. Despite this fundamental advance in methodology, liabilities imposed by the dual political-empirical origins of race persist. On the one hand, an optimistic prediction can be made that just as geology made it possible to overturn the myth of the recent creation of the earth and evolution told us where the living world came from, molecular genetics will end the use of race in biology. At the same time, because race is fundamentally a political and not a scientific idea, it is possible that only a political intervention will relieve us of the burden of race. PMID:24186487

    On the Planet Earth, oceans and seas today correspond to the largest volume offered to Life. Roughly, 275,000 species have been described from marine environments, only representing some 15% of all the present known living. But marine biomass can be enormous. Life appeared in the ancestral ocean 3 800 million years ago and determining events occurred there: appearance of the nuclear membrane and cell nucleus, "pluricellularity", capture of bacteria transformed into organelles, then sexuality. On the 33 phyla existing today on the Earth, 12 never have left the ocean and are exclusively marine. Such biodiversity, archaism of characters, organisational and behavioural patterns make these marine organisms an excellent reservoir for identifying and extracting very interesting pharmacological and cosmetic molecules (>5 000 today) and/or to represent very pertinent "models" for basic and applied research. Relationships between ocean and public health are physical, chemical, biological and physiological. A few marine species as "models" set the base for major advances in life sciences recognized by several Nobel Prices: from the discovery of phagocytosis to anaphylactic shock, and including nervous influx transmission, memory molecular bases, cyclins discovery, eye organisation, neurotransmitter membrane receptors, bases of the specific immune system... These marine models are very useful to understand the origin and functioning of important living mechanisms in the human and sometimes to deduce applications for efficient treatments. Ocean supplies mankind with renewable living resources, much threatened today. We have to manage and protect these to maintain ecosystems, stocks and biodiversity. Only because of the greenhouse effect and anthropic emissions, temperature is globally increasing: and, what if (tomorrow?) one million species would disappear (before 2050) because of global warming?

    One of the greatest advances in molecular and cell biology was the discovery of the Induced Pluripotent Stem cells (iPS) in mice, by Shinya Yamanka and his team in 2006. The possibility that these cells can be generated also in humans opens up unexpected ways of development for biomedicine. Its main contribution is the creation of a strong protocol that takes into account three major advances in biology such as; nuclear transfer techniques, the discovery of transcription factors associated with pluripotency and the isolation of mouse embryonic stem cells. A protocol that can be easily replicated in other laboratories to have the oportunity to design tests that allow modeling of many incurable diseases, drug testing for human cells or explore the possibilities of autologous transplants of tissues or organs. Yamanaka ethical motivation to find an alternative to embryonic stem cells (ES) and prevent the destruction of embryos produced by In Vitro Fertilization techniques (IVF), has proved to be a research model, in which the intuition of the ethical principles and its application in advanced biotechnology projects, has meant the opening of a whole new way of understanding the biology of embryonic development. It is clear that development, biologically understood (puede ser también ″treated″; tratado), is not a one-way street. The possibilities to deepen into the foundations of molecular biology and genetics, along with the expectations of its clinical applications have earned Yamanka the Nobel Prize in Medicine 2012, along with another great scholar Sir John Gurdon, discoverer of nuclear transfer techniques.

    The Space Shuttle Program provided many opportunities to study the role of spaceflight on human life for over 30 years and represented the longest and largest US human spaceflight program. Outcomes of the research were understanding the effect of spaceflight on human physiology and performance, countermeasures, operational protocols, and hardware. The Shuttle flights were relatively short, < 16 days and routinely had 4 to 6 crewmembers for a total of 135 flights. Biomedical research was conducted on the Space Shuttle using various vehicle resources. Specially constructed pressurized laboratories called Spacelab and SPACEHAB housed many laboratory instruments to accomplish experiments in the Shuttle s large payload bay. In addition to these laboratory flights, nearly every mission had dedicated human life science research experiments conducted in the Shuttle middeck. Most Shuttle astronauts participated in some life sciences research experiments either as test subjects or test operators. While middeck experiments resulted in a low sample per mission compared to many Earth-based studies, this participation allowed investigators to have repetition of tests over the years on successive Shuttle flights. In addition, as a prelude to the International Space Station (ISS), NASA used the Space Shuttle as a platform for assessing future ISS hardware systems and procedures. The purpose of this panel is to provide an understanding of science integration activities required to implement Shuttle research, review biomedical research, characterize countermeasures developed for Shuttle and ISS as well as discuss lessons learned that may support commercial crew endeavors. Panel topics include research integration, cardiovascular physiology, neurosciences, skeletal muscle, and exercise physiology.

    Mixed methods studies, in which qualitative and quantitative methods are combined in a single program of inquiry, can be valuable in biomedical and health services research, where the complementary strengths of each approach can yield greater insight into complex phenomena than either approach alone. Although interest in mixed methods is growing among science funders and investigators, written guidance on how to conduct and assess rigorous mixed methods studies is not readily accessible to the general readership of peer-reviewed biomedical and health services journals. Furthermore, existing guidelines for publishing mixed methods studies are not well known or applied by researchers and journal editors. Accordingly, this paper is intended to serve as a concise, practical resource for readers interested in core principles and practices of mixed methods research. We briefly describe mixed methods approaches and present illustrations from published biomedical and health services literature, including in cardiovascular care, summarize standards for the design and reporting of these studies, and highlight four central considerations for investigators interested in using these methods.

    In this study, we explore community members’ overall understanding and experience with biomedical research engagement. We conducted a qualitative analysis to explore a concept that emerged, but was not specifically addressed in a pre-existing dataset obtained using four focus group sessions with 30 urban-dwelling community members. Transcripts were read in an iterative process and an emergent content analysis performed. Five main themes were identified: (a) engaging in research to contribute to personal or greater good; (b) hierarchy of trust; (c) the importance of disclosure and transparency; (d) practical barriers to research engagement; and (e) fear of research procedures. Community members view research engagement as a collaborative process whereby community members and researchers are involved in all stages of the investigation. Focusing on research engagement, and not merely participation, may enhance community knowledge of the research process and advance scientific knowledge. PMID:26825482

    Several recent grants from the National Institutes of Health to the Universities of Wyoming, Idaho, and Montana have created a unique opportunity for collaboration in biomedical research among the three schools, as well as the community colleges in the region. NIH Center of Biomedical Research Excellence (COBRE) programs at Wyoming have been established to study the biological effect of nitric oxide and to investigate stressors that can contribute to the progression of cardiovascular disease. Funding from these and related grants have significantly upgraded Wyoming bioimaging and microscopy facilities, as well as provided support for faculty and students in a variety of research disciplines. In order to enhance these research efforts, the Center for Rural Health Research and Education at the University of Wyoming is spearheading an effort to create an Internet-based system for sharing data and research resources among the involved sites. This paper describes how such a "collaboratory" could be designed, using techniques developed for distributed research and development in the computer industry. The system, as envisioned, will support remote data acquisition, management, and visualization, while providing security in the form of authorization and authentication of users and virtual private networking for data transmitted between nodes of the network.

    Since domestication, pigs have been used extensively in agriculture and kept as companion animals. More recently they have been used in biomedical research, given they share many physiological and anatomical similarities with humans. Recent technological advances in assisted reproduction, somatic cell cloning, stem cell culture, genome editing, and transgenesis now enable the creation of unique porcine models of human diseases. Here, we highlight the potential applications and advantages of using pigs, particularly minipigs, as indispensable large animal models in fundamental and clinical research, including the development of therapeutics for inherited and chronic disorders, and cancers.

    To address biosecurity issues, government agencies, academic institutions, and professional societies have developed policies concerning the publication of "dual-use" biomedical research-that is, research that could be readily applied to cause significant harm to the public, the environment, or national security. We conducted an e-mail survey of life science journals to determine the percentage that have a dual-use policy. Of the 155 journals that responded to our survey (response rate 39%), only 7.7% stated that they had a written dual-use policy and only 5.8% said they had experience reviewing dual-use research in the past 5 years. Among the potential predictors we investigated, the one most highly associated with a journal having a written dual-use policy was membership in the Nature Publishing Group (positive association). When considered individually, both previous experience with reviewing dual-use research and the journal's impact factor appeared to be positively associated with having a written dual-use policy, but only the former remained significant after adjusting for publishing group. Although preventing the misuse of scientific research for terrorist or criminal purposes is an important concern, few biomedical journals have dual-use review policies. Journals that are likely to review research that raises potential dual-use concerns should consider developing dual-use policies.

    Facing modern developments of medicine and biomedical researches, religious communities are a strong source of ethics principles and orientations. Human dignity does not disappear after life, in a context of biomedical research on cadavers. Moral, political, social and scientific aspects of research on human cadavers (mainly autopsies) have been widely discussed in biomedical publications, whereas the religious ones (which could be predominant for some) have rarely been analyzed and presented. This article will present the results of a survey carried out a French Benedictine Abbey (relative to death, cadaver's status and biomedical research) and subsequent Christian background according to canonic texts and practical cases from anthropological, historical, archeological and biomedical origin.

    2015-11-01

    Current ethics and good clinical practice guidelines address various aspects of pharmaceutical research and development, but do not comprehensively address the bioethical responsibilities of sponsors. To fill this void, in 2010 Eli Lilly and Company developed and implemented a Bioethics Framework for Human Biomedical Research to guide ethical decisions. (See our companion article that describes how the framework was developed and implemented and provides a critique of its usefulness and limitations.) This paper presents the actual framework that serves as a company resource for employee education and bioethics deliberations. The framework consists of four basic ethical principles and 13 essential elements for ethical human biomedical research and resides within the context of our company's mission, vision and values. For each component of the framework, we provide a high-level overview followed by a detailed description with cross-references to relevant well regarded guidance documents. The principles and guidance described should be familiar to those acquainted with research ethics. Therefore the novelty of the framework lies not in the foundational concepts presented as much as the attempt to specify and compile a sponsor's bioethical responsibilities to multiple stakeholders into one resource. When such a framework is employed, it can serve as a bioethical foundation to inform decisions and actions throughout clinical planning, trial design, study implementation and closeout, as well as to inform company positions on bioethical issues. The framework is, therefore, a useful tool for translating ethical aspirations into action - to help ensure pharmaceutical human biomedical research is conducted in a manner that aligns with consensus ethics principles, as well as a sponsor's core values.

  8. Applying environmental product design to biomedical products research.

    PubMed Central

    Messelbeck, J; Sutherland, L

    2000-01-01

    The principal themes for the Biomedical Research and the Environment Conference Committee on Environmental Economics in Biomedical Research include the following: healthcare delivery companies and biomedical research organizations, both nonprofit and for-profit, need to improve their environmental performance; suppliers of healthcare products will be called upon to support this need; and improving the environmental profile of healthcare products begins in research and development (R&D). The committee report begins with requirements from regulatory authorities (e.g., U.S. Environmental Protection Agency [EPA], the U.S. Food and Drug Administration), and the healthcare delivery sector). The 1998 American Hospital Association and EPA Memorandum of Understanding to reduce solid waste and mercury from healthcare facilities is emblematic of these requirements. The dominant message from the requirements discussion is to ensure that R&D organizations do not ignore customer, environmental, and regulatory requirements in the early stages of product development. Several representatives from healthcare products manufacturers presented their companies' approaches to meeting these requirements. They reported on efforts to ensure that their R&D processes are sensitive to the environmental consequences from manufacturing, distributing, using, and disposing of healthcare products.

    The principal themes for the Biomedical Research and the Environment Conference Committee on Environmental Economics in Biomedical Research include the following: healthcare delivery companies and biomedical research organizations, both nonprofit and for-profit, need to improve their environmental performance; suppliers of healthcare products will be called upon to support this need; and improving the environmental profile of healthcare products begins in research and development (R&D). The committee report begins with requirements from regulatory authorities (e.g., U.S. Environmental Protection Agency [EPA], the U.S. Food and Drug Administration), and the healthcare delivery sector). The 1998 American Hospital Association and EPA Memorandum of Understanding to reduce solid waste and mercury from healthcare facilities is emblematic of these requirements. The dominant message from the requirements discussion is to ensure that R&D organizations do not ignore customer, environmental, and regulatory requirements in the early stages of product development. Several representatives from healthcare products manufacturers presented their companies' approaches to meeting these requirements. They reported on efforts to ensure that their R&D processes are sensitive to the environmental consequences from manufacturing, distributing, using, and disposing of healthcare products. These reports describe representatives' awareness of requirements and the unique approaches their R&D organizations have taken to meet these requirements. All representatives reported that their R&D organizations have embraced environmental product design because it avoids the potential of returning products to R&D to improve the environmental profile.

    Background Working together efficiently and effectively presents a significant challenge in large-scale, complex, interdisciplinary research projects. Collaboratories are a nascent method to help meet this challenge. However, formal collaboratories in biomedical research centers are the exception rather than the rule. Objective The main purpose of this paper is to compare and describe two collaboratories that used off-the-shelf tools and relatively modest resources to support the scientific activity of two biomedical research centers. The two centers were the Great Lakes Regional Center for AIDS Research (HIV/AIDS Center) and the New York University Oral Cancer Research for Adolescent and Adult Health Promotion Center (Oral Cancer Center). Methods In each collaboratory, we used semistructured interviews, surveys, and contextual inquiry to assess user needs and define the technology requirements. We evaluated and selected commercial software applications by comparing their feature sets with requirements and then pilot-testing the applications. Local and remote support staff cooperated in the implementation and end user training for the collaborative tools. Collaboratory staff evaluated each implementation by analyzing utilization data, administering user surveys, and functioning as participant observers. Results The HIV/AIDS Center primarily required real-time interaction for developing projects and attracting new participants to the center; the Oral Cancer Center, on the other hand, mainly needed tools to support distributed and asynchronous work in small research groups. The HIV/AIDS Center’s collaboratory included a center-wide website that also served as the launch point for collaboratory applications, such as NetMeeting, Timbuktu Conference, PlaceWare Auditorium, and iVisit. The collaboratory of the Oral Cancer Center used Groove and Genesys Web conferencing. The HIV/AIDS Center was successful in attracting new scientists to HIV/AIDS research, and members

  11. Irreproducibility in Preclinical Biomedical Research: Perceptions, Uncertainties, and Knowledge Gaps.

    PubMed

    Jarvis, Michael F; Williams, Michael

    2016-04-01

    Concerns regarding the reliability of biomedical research outcomes were precipitated by two independent reports from the pharmaceutical industry that documented a lack of reproducibility in preclinical research in the areas of oncology, endocrinology, and hematology. Given their potential impact on public health, these concerns have been extensively covered in the media. Assessing the magnitude and scope of irreproducibility is limited by the anecdotal nature of the initial reports and a lack of quantitative data on specific failures to reproduce published research. Nevertheless, remediation activities have focused on needed enhancements in transparency and consistency in the reporting of experimental methodologies and results. While such initiatives can effectively bridge knowledge gaps and facilitate best practices across established and emerging research disciplines and therapeutic areas, concerns remain on how these improve on the historical process of independent replication in validating research findings and their potential to inhibit scientific innovation.

  12. Race and ancestry in biomedical research: exploring the challenges

    PubMed Central

    2009-01-01

    The use of race in biomedical research has, for decades, been a source of social controversy. However, recent events, such as the adoption of racially targeted pharmaceuticals, have raised the profile of the race issue. In addition, we are entering an era in which genomic research is increasingly focused on the nature and extent of human genetic variation, often examined by population, which leads to heightened potential for misunderstandings or misuse of terms concerning genetic variation and race. Here, we draw together the perspectives of participants in a recent interdisciplinary workshop on ancestry and health in medicine in order to explore the use of race in research issue from the vantage point of a variety of disciplines. We review the nature of the race controversy in the context of biomedical research and highlight several challenges to policy action, including restrictions resulting from commercial or regulatory considerations, the difficulty in presenting precise terminology in the media, and drifting or ambiguous definitions of key terms.

    Crucial prerequisites for the development of safe preclinical protocols in biomedical research are suitable animal models that would allow for human-related validation of valuable research information gathered from experimentation with lower mammals. In this sense, the miniature pig, sharing many physiological similarities with humans, offers several breeding and handling advantages (when compared to non-human primates), making it an optimal species for preclinical experimentation. The present review offers several examples taken from current research in the hope of convincing the reader that the porcine animal model has gained massively in importance in biomedical research during the last few years. The adduced examples are taken from the following fields of investigation: (a) the physiology of reproduction, where pig oocytes are being used to study chromosomal abnormalities (aneuploidy) in the adult human oocyte; (b) the generation of suitable organs for xenotransplantation using transgene expression in pig tissues; (c) the skin physiology and the treatment of skin defects using cell therapy-based approaches that take advantage of similarities between pig and human epidermis; and (d) neurotransplantation using porcine neural stem cells grafted into inbred miniature pigs as an alternative model to non-human primates xenografted with human cells.

  14. Can small institutes address some problems facing biomedical researchers?

    PubMed

    Sheetz, Michael P

    2014-11-01

    At a time of historically low National Institutes of Health funding rates and many problems with the conduct of research (unfunded mandates, disgruntled reviewers, and rampant paranoia), there is a concern that biomedical research as a profession is waning in the United States (see "Rescuing US biomedical research from its systemic flaws" by Alberts and colleagues in the Proceedings of the National Academy of Sciences). However, it is wonderful to discover something new and to tackle tough puzzles. If we could focus more of our effort on discussing scientific problems and doing research, then we could be more productive and perhaps happier. One potential solution is to focus efforts on small thematic institutes in the university structure that can provide a stimulating and supportive environment for innovation and exploration. With an open-lab concept, there are economies of scale that can diminish paperwork and costs, while providing greater access to state-of-the-art equipment. Merging multiple disciplines around a common theme can catalyze innovation, and this enables individuals to develop new concepts without giving up the credit they deserve, because it is usually clear who did the work. Small institutes do not solve larger systemic problems but rather enable collective efforts to address the noisome aspects of the system and foster an innovative community effort to address scientific problems.

  15. Improving biomedical journals' ethical policies: the case of research misconduct.

    PubMed

    Bosch, Xavier

    2014-09-01

    Scientific journals may incur scientific error if articles are tainted by research misconduct. While some journals' ethical policies, especially those on conflicts of interest, have improved over recent years, with some adopting a uniform approach, only around half of biomedical journals, principally those with higher impact factors, currently have formal misconduct policies, mainly for handling allegations. Worryingly, since a response to allegations would reasonably require an a priori definition, far fewer journals have publicly available definitions of misconduct. While some journals and editors' associations have taken significant steps to prevent and detect misconduct and respond to allegations, the content, visibility of and access to these policies varies considerably. In addition, while the lack of misconduct policies may prompt and maintain a de novo approach for journals, potentially causing stress, publication delays and even legal disputes, the lack of uniformity may be a matter of contention for research stakeholders such as editors, authors and their institutions, and publishers. Although each case may need an individual approach, I argue that posting highly visible, readily accessible, comprehensive, consistent misconduct policies could prevent the publication of fraudulent papers, increase the number of retractions of already published papers and, perhaps, reduce research misconduct. Although legally problematic, a concerted approach, with sharing of information between editors, which is clearly explained in journal websites, could also help. Ideally, journals, editors' associations, and publishers should seek consistency and homogenise misconduct policies to maintain public confidence in the integrity of biomedical research publications.

    It is a fact that p values are commonly used for inference in biomedical and other social fields of research. Unfortunately, the role of p value is very often misused and misinterpreted; that is why it has been recommended the use of resampling methods, like the bootstrap method, to calculate the confidence interval, which provides more robust results for inference than does p value. In this review a discussion is made about the use of p values through hypothesis testing and its alternatives using resampling methods to develop confidence intervals of the tested statistic or effect measure.

    When the U.S. first embarked on a manned space flight program, NASA's use of medical telescience was focused on crew health monitoring. In recent years, medical telescience use has been expanded to include support of basic research in space medicine. It enables ground support personnel to assist on-board crews in the performance of experiments and improves the quality and quantity of data return. NASA is continuing to develop its telescience capabilities. Future plans include telemedicine that will enable physicians on Earth to support crewmembers during flight and telescience that will enable investigators at their home institutions to support and conduct in-flight medical research. NASA's use of telescience for crew safety and biomedical research from Project Mercury to the present is described and NASA's plans for the future are presented.

  2. Towards an ethics safe harbor for global biomedical research

    2014-01-01

    Although increasingly global, data-driven genomics and other ‘omics’-focused research hold great promise for health discoveries, current research ethics review systems around the world challenge potential improvements in human health from such research. To overcome this challenge, we propose a ‘Safe Harbor Framework for International Ethics Equivalency’ that facilitates the harmonization of ethics review of specific types of data-driven international research projects while respecting globally transposable research ethics norms and principles. The Safe Harbor would consist in part of an agency supporting an International Federation for Ethics Review (IFER), formed by a voluntary compact among countries, granting agencies, philanthropies, institutions, and healthcare, patient advocacy, and research organizations. IFER would be both a central ethics review body, and also a forum for review and follow-up of policies concerning ethics norms for international research projects. It would be built on five principle elements: (1) registration, (2) compliance review, (3) recognition, (4) monitoring and enforcement, and (5) public participation. The Safe Harbor would create many benefits for researchers, countries, and the general public, and may eventually have application beyond (gen)omics to other areas of biomedical research that increasingly engage in secondary use of data and present only negligible risks.

    2008-01-01

    The current situation in medicine has been described as a crisis of credibility, as the profit motive of industry has taken control of clinical trials and the dissemination of data. Pharmaceutical companies maintain a stranglehold over the content of medical journals in three ways: (1) by ghostwriting articles that bias the results of clinical trials, (2) by the sheer economic power they exert on journals due to the purchase of drug advertisements and journal reprints, and (3) by the threat of legal action against those researchers who seek to correct the misrepresentation of study results. This paper argues that Karl Popper's critical rationalism provides a corrective to the failure of academic freedom in biomedical research. PMID:22013356

    Targeted proteomics technique has emerged as a powerful protein quantification tool in systems biology, biomedical research, and increasing for clinical applications. The most widely used targeted proteomics approach, selected reaction monitoring (SRM), also known as multiple reaction monitoring (MRM), can be used for quantification of cellular signaling networks and preclinical verification of candidate protein biomarkers. As an extension to our previous review on advances in SRM sensitivity herein we review recent advances in the method and technology for further enhancing SRM sensitivity (from 2012 to present), and highlighting its broad biomedical applications in human bodily fluids, tissue and cell lines. Furthermore, we also review two recently introduced targeted proteomics approaches, parallel reaction monitoring (PRM) and data-independent acquisition (DIA) with targeted data extraction on fast scanning high-resolution accurate-mass (HR/AM) instruments. Such HR/AM targeted quantification with monitoring all target product ions addresses SRM limitations effectively in specificity and multiplexing; whereas when compared to SRM, PRM and DIA are still in the infancy with a limited number of applications. Thus, for HR/AM targeted quantification we focus our discussion on method development, data processing and analysis, and its advantages and limitations in targeted proteomics. Finally, general perspectives on the potential of achieving both high sensitivity and high sample throughput for large-scale quantification of hundreds of target proteins are discussed.

    A large number of papers are appearing in the biomedical engineering literature that describe the use of machine learning techniques to develop classifiers for detection or diagnosis of disease. However, the usefulness of this approach in developing clinically validated diagnostic techniques so far has been limited and the methods are prone to overfitting and other problems which may not be immediately apparent to the investigators. This commentary is intended to help sensitize investigators as well as readers and reviewers of papers to some potential pitfalls in the development of classifiers, and suggests steps that researchers can take to help avoid these problems. Building classifiers should be viewed not simply as an add-on statistical analysis, but as part and parcel of the experimental process. Validation of classifiers for diagnostic applications should be considered as part of a much larger process of establishing the clinical validity of the diagnostic technique.

    Genome-wide association studies (GWAS) have identified many risk loci for complex diseases, but effect sizes are typically small and information on the underlying biological processes is often lacking. Associations with metabolic traits as functional intermediates can overcome these problems and potentially inform individualized therapy. Here we report a comprehensive analysis of genotype-dependent metabolic phenotypes using a GWAS with non-targeted metabolomics. We identified 37 genetic loci associated with blood metabolite concentrations, of which 25 show effect sizes that are unusually high for GWAS and account for 10-60% differences in metabolite levels per allele copy. Our associations provide new functional insights for many disease-related associations that have been reported in previous studies, including those for cardiovascular and kidney disorders, type 2 diabetes, cancer, gout, venous thromboembolism and Crohn's disease. The study advances our knowledge of the genetic basis of metabolic individuality in humans and generates many new hypotheses for biomedical and pharmaceutical research.

    Responsibility for protection of research participants from harm and exploitation rests on Research Ethics Committees and principal investigators. The Nigerian National Code of Health Research Ethics defines responsibilities of stakeholders in research so its knowledge among researchers will likely aid ethical conduct of research. The levels of awareness and knowledge of the Code among biomedical researchers in southern Nigerian research institutions was assessed. Four institutions were selected using a stratified random sampling technique. Research participants were selected by purposive sampling and completed a pre-tested structured questionnaire. A total of 102 biomedical researchers completed the questionnaires. Thirty percent of the participants were aware of the National Code though 64% had attended at least one training seminar in research ethics. Twenty-five percent had a fairly acceptable knowledge (scores 50%-74%) and 10% had excellent knowledge of the code (score ≥75%). Ninety-five percent expressed intentions to learn more about the National Code and agreed that it is highly relevant to the ethical conduct of research. Awareness and knowledge of the Code were found to be very limited among biomedical researchers in southern Nigeria. There is need to improve awareness and knowledge through ethics seminars and training. Use of existing Nigeria-specific online training resources is also encouraged.

    Realizing scientific biomedical research conducted on human-beings demands obeying ample ethical rules. However, states keep independence in the means of implementing deontological guidelines to legislative acts. The aim of the article is to compare rules of law relative to protection of scientific biomedical research participants in two European Union member states--France and Poland. French regulations cover more types of scientific biomedical research than those in Poland. In France almost all types of interventional scientific biomedical research including research on human biological samples and research on cosmetics are covered by the rules of law. Polish regulations are limited to interventional research conducted by doctors and dentists. In both states projects of clinical trials of medicinal products demands double acceptance - from bioethics committee and from competent state authority. In protection of scientific biomedical research participants the role of state authority competent for personal data is more vital in France than it is in Poland. In France there is also National Ethics Advisory Committee whereas in Poland there is no such institution. The systems protecting scientific biomedical research participants differs therefore in both states in many vital aspects and French measures cover more types of scientific biomedical research, hence the level of participants protection in various types of research is more equitable.

    Pluripotent stem cells including embryonic stem cells (ESCs), embryonic germ cells (EGCs), and induced pluripotent stem cells (iPSCs) are capable of self-renew and limitlessly proliferating in vitro with undifferentiated characteristics. They are able to differentiate in vitro, spontaneously or responding to suitable signals, into cells of all three primary germ layers. Consequently, these pluripotent stem cells will be valuable sources for cell replacement therapy in numerous disorders. However, the promise of human ESCs and EGCs is cramped by the ethical argument about destroying embryos and fetuses for cell line creation. Moreover, there are still carcinogenic risks existing toward the goal of clinical application for human ESCs, EGCs, and iPSCs. Therefore, a suitable animal model for stem cell research will benefit the further development of human stem cell technology. The pigs, on the basis of their similarity in anatomy, immunology, physiology, and biochemical properties, have been wide used as model animals in the study of various human diseases. The development of porcine pluripotent stem cell lines will hold the opportunity to provide an excellent material for human counterpart to the transplantation in biomedical research and further development of cell-based therapeutic strategy.

    Biomedical researchers often work with massive, detailed and heterogeneous datasets. These datasets raise new challenges of information organization and management for scientific interpretation, as they demand much of the researchers' time and attention. The current study investigated the nature of the problems that researchers face when dealing with such data. Four major problems identified with existing biomedical scientific information management methods were related to data organization, data sharing, collaboration, and publications. Therefore, there is a compelling need to develop an efficient and user-friendly information management system to handle the biomedical research data. This study evaluated the implementation of an information management system, which was introduced as part of the collaborative research to increase scientific productivity in a research laboratory. Laboratory members seemed to exhibit frustration during the implementation process. However, empirical findings revealed that they gained new knowledge and completed specified tasks while working together with the new system. Hence, researchers are urged to persist and persevere when dealing with any new technology, including an information management system in a research laboratory environment.

    The Function Biomedical Informatics Research Network (FBIRN) developed methods and tools for conducting multi-scanner functional magnetic resonance imaging (fMRI) studies. Method and tool development were based on two major goals: 1) to assess the major sources of variation in fMRI studies conducted across scanners, including instrumentation, acquisition protocols, challenge tasks, and analysis methods, and 2) to provide a distributed network infrastructure and an associated federated database to host and query large, multi-site, fMRI and clinical data sets. In the process of achieving these goals the FBIRN test bed generated several multi-scanner brain imaging data sets to be shared with the wider scientific community via the BIRN Data Repository (BDR). The FBIRN Phase 1 data set consists of a traveling subject study of 5 healthy subjects, each scanned on 10 different 1.5 to 4 T scanners. The FBIRN Phase 2 and Phase 3 data sets consist of subjects with schizophrenia or schizoaffective disorder along with healthy comparison subjects scanned at multiple sites. In this paper, we provide concise descriptions of FBIRN's multi-scanner brain imaging data sets and details about the BIRN Data Repository instance of the Human Imaging Database (HID) used to publicly share the data.

  3. High resolution autofocus for spatial temporal biomedical research

    Maintaining focus has been a critical but challenging issue in optical microscopy, particularly for microscopic imaging systems currently used in biomedical research. During live cell imaging, environmental temperature fluctuations and other factors contribute to the unavoidable focus drift. For single molecular imaging and super resolution, focus drift can be significant even over short durations. The current commercial and experimental solutions are either optically complicated, expensive, or with limited axial resolution. Here, we present a simple autofocus solution based on low cost solid state laser and imaging sensor. By improving the optical train design and using real-time data analysis, improvement in axial resolution by approximately two orders of magnitudes over the focal depth of microscope objectives can be achieved. This solution has been tested for prolonged live cell imaging for fast ramping up in environmental chamber temperature and large daily swing in room temperature. In addition, this system can be used to spatial-temporally measure the surface for three-dimensional cell culture and tissue engineering, with flexibility that exceeds commercially available systems.

    The nature of this project is to equip and support research in nanoengineered systems for biomedical, bioenvironmental, and bioenergy applications. Funds provided by the Department of Energy (DoE) under this Congressional Directive were used to support two ongoing research projects at Louisiana Tech University in biomedical, bioenvironmental, and bioenergy applications. Two major projects (Enzyme Immobilization for Large Scale Reactors to Reduce Cellulosic Ethanol Costs, and Nanocatalysts for Coal and Biomass Conversion to Diesel Fuel) and to fund three to five additional seed projects were funded using the project budget. The project funds also allowed the purchase and repair of sophisticated research equipment that will support continued research in these areas for many years to come. Project funds also supported faculty, graduate students, and undergraduate students, contributing to the development of a technically sophisticated work force in the region and the State. Descriptions of the technical accomplishments for each funded project are provided. Biofuels are an important part of the solution for sustainable transportation fuel and energy production for the future. Unfortunately, the country's appetite for fuel cannot be satisfied with traditional sugar crops such as sugar cane or corn. Emerging technologies are allowing cellulosic biomass (wood, grass, stalks, etc.) to also be converted into ethanol. Cellulosic ethanol does not compete with food production and it has the potential to decrease greenhouse gas (GHG) emissions by 86% versus current fossil fuels (current techniques for corn ethanol only reduce greenhouse gases by 19%). Because of these advantages, the federal government has made cellulosic ethanol a high priority. The Energy Independence and Security Act of 2007 (EISA) requires a minimum production of at least 16 billion gallons of cellulosic ethanol by 2022. Indeed, the Obama administration has signaled an ambitious commitment of achieving 2

    This article focuses on a synthesis of knowledge about healthy aging research in human beings and then synthesized nurse-led research in gerontology and geriatrics that use biomarkers. Healthy aging research has attracted considerable attention in the biomedical and basic sciences within the context of four major areas: (a) genetic variations as an expression of successful or unsuccessful aging; (b) caloric restriction as an intervention to slow the progression of aging; (c) immunological aging; (d) neurobiology of the aging brain. A systematic review of the literature was performed to identify nurse-led geriatric-related biomarker research. Nurse researchers who have chosen to integrate biomarkers as part of their research studies have been working in six focal areas, which are reviewed: health promotion within risk populations, cancer, vascular disease, Alzheimer’s disease, caregiving, and complementary therapies. The article provides a discussion of contributions to date, identifying existing gaps and future research opportunities. PMID:20077975

    Laboratory animal models are limited by scientific constraints on human applicability, and increasing regulatory restrictions, driven by social concerns. Reliance on laboratory animals also incurs marked - and in some cases, prohibitive - logistical challenges, within high-throughput chemical testing programmes, such as those currently underway within Europe and the US. However, a range of non-animal methodologies is available within biomedical research and toxicity testing. These include: mechanisms to enhance the sharing and assessment of existing data prior to conducting further studies, and physicochemical evaluation and computerised modelling, including the use of structure-activity relationships and expert systems. Minimally-sentient animals from lower phylogenetic orders or early developmental vertebral stages may be used, as well as microorganisms and higher plants. A variety of tissue cultures, including immortalised cell lines, embryonic and adult stem cells, and organotypic cultures, are also available. In vitro assays utilising bacterial, yeast, protozoal, mammalian or human cell cultures exist for a wide range of toxic and other endpoints. These may be static or perfused, and may be used individually, or combined within test batteries. Human hepatocyte cultures and metabolic activation systems offer potential assessment of metabolite activity and organ-organ interaction. Microarray technology may allow genetic expression profiling, increasing the speed of toxin detection, well prior to more invasive endpoints. Enhanced human clinical trials utilising micro- dosing, staggered dosing, and more representative study populations and durations, as well as surrogate human tissues, advanced imaging modalities and human epidemiological, sociological and psycho- logical studies, may increase our understanding of illness aetiology and pathogenesis, and facilitate the development of safe and effective pharmacologic interventions.

    Nanodiamonds containing color-centers produce non-quenching fluorescence that is easily detected. This makes them useful for cellular, proteomic and genomic applications. However, fluorescent nanodiamonds have yet to become popular in the biomedical research community as labeling reagents. We discuss production of nanodiamonds with distinct color-centers and assess their biocompatibility and techniques for bioconjugation. Fluorescent diamonds were fabricated by electron irradiation of high-pressure, high-temperature micron-sized diamonds which generated diamonds with vacancy-related defects (V). These diamonds were annealed to create nitrogen vacancy (NV)-centers then following a milling step were fractionated into nanoparticle sizes of 30, 60, and 95 nm. Optical characterization of Vand NV-center diamonds demonstrated fluorescence in two distinct green and red channels, respectively. In vitro studies demonstrated that these nanodiamonds are biocompatible and readily taken up by murine macrophage cells. Quantification of NV-center nanodiamond uptake by flow cytometry, showed that uptake was independent of nanodiamond size. Confocal microscopy demonstrated that NV-center nanodiamonds accumulate within the cytoplasm of these cells. NV-center nanodiamonds were then conjugated with streptavidin using a short polyethylene chain as linker. Conjugation was confirmed via a catalytic assay employing biotinylated-horseradish peroxidase. We present a technique for large-scale production of biocompatible conjugated V- or NV-center nanodiamonds. Functional testing is essential for standardization of fluorescent nanodiamond bioconjugates and quality control. Large-scale production of bioconjugated fluorescent nanodiamonds is crucial to their development as novel tools for biological and medical applications.

  14. The Central Importance of Laboratories for Reducing Waste in Biomedical Research.

    PubMed

    Stroth, Nikolas

    2016-12-01

    The global biomedical research enterprise is driving substantial advances in medicine and healthcare. Yet it appears that the enterprise is rather wasteful, falling short of its true innovative potential. Suggested reasons are manifold and involve various stakeholders, such that there is no single remedy. In the present paper, I will argue that laboratories are the basic working units of the biomedical research enterprise and an important site of action for corrective intervention. Keeping laboratories relatively small will enable better training and mentoring of individual scientists, which in turn will yield better performance of the scientific workforce. The key premise of this argument is that people are at the heart of the successes and failures of biomedical research, yet the human dimension of science has been unduly neglected in practice. Renewed focus on the importance of laboratories and their constituent scientists is one promising approach to reducing waste and increasing efficiency within the biomedical research enterprise.

    Latinos are under-represented in biomedical research conducted in the United States, impeding disease prevention and treatment efforts for this growing demographic group. We gathered perceptions of biomedical research and gauged willingness to participate through elicitation interviews and focus groups with Latinos living on the U.S.-Mexico border. Themes that emerged included a strong willingness to participate in biomedical studies and suggested that Latinos may be under-represented due to limited formal education and access to health information, not distrust. The conflation of research and clinical care was common and motivated participation. Outreach efforts and educational interventions to inform Latinos of participation opportunities and clarify harms and benefits associated with biomedical research participation will be essential to maintain trust within Latino communities.

  3. Privatized biomedical research, public fears, and the hazards of government regulation: lessons from stem cell research.

    PubMed

    Resnik, D B

    1999-01-01

    This paper discusses the hazards of regulating controversial biomedical research in light of the emergence of powerful, multi-national biotechnology corporations. Prohibitions on the use of government funds can simply force controversial research into the private sphere, and unilateral or multilateral research bans can simply encourage multi-national companies to conduct research in countries that lack restrictive laws. Thus, a net effect of government regulation is that research migrates from the public to the private sphere. Because private research receives less oversight and external scrutiny than public research, it can threaten the welfare and rights of human subjects, scientific progress and openness, and the quality of the approval process for new biomedical technologies. In order to avoid the harmful effects of government regulation of biotechnology, society should promote meaningful discussion and dialogue among scientists, industry leaders, and the public before resorting to regulatory solutions. Legislative or executive initiatives should be applied with great discretion and care, and should be crafted in such a way that they protect public health and safety, promote scientific progress, and avoid the hazards of privatized research and polarized debates.

  9. "Race" and "ethnicity" in biomedical research: how do scientists construct and explain differences in health?

    PubMed

    Lee, Catherine

    2009-03-01

    Social and biomedical scientists, journal editors, and public health officials continue to debate the merits of the use of race and ethnicity in health-related research. As biomedical research focuses on issues of racial or ethnic health disparities, it remains unclear how biomedical scientists investigate race or ethnicity and health. This paper examines how biomedical researchers construct and analyze race or ethnicity in their studies and what conclusions they make about difference and health. Using content analysis of 204 biomedical research journal publications, which were supported by grants won from the National Cancer Institute of the National Institutes of Health in the USA, I demonstrate that although authors tended to see race or ethnicity as important and significant in their research, they rarely defined or operationalized the concepts adequately. Moreover, when presenting findings of racial or ethnic difference, authors generally did not provide explanations of the difference. I argue that this under-theorized and unspecified use of race or ethnicity and the biological conclusions drawn about health and difference have the potential to reify "race" and to limit our thinking about what these biomedical differences suggest about health disparities and inequalities in general.

    With the founding of the National Institute of Biomedical Imaging and Bioengineering (NIBIB) in 1999, the National Institutes of Health (NIH) made explicit its dedication to expanding research in biomedical engineering. Ten years later, we sought to examine how closely federal funding for biomedical engineering aligns with U.S. health priorities. Using a publicly accessible database of research projects funded by the NIH in 2008, we identified 641 grants focused on biomedical engineering, 48% of which targeted specific diseases. Overall, we found that these disease-specific NIH-funded biomedical engineering research projects align with national health priorities, as quantified by three commonly utilized measures of disease burden: cause of death, disability-adjusted survival losses, and expenditures. However, we also found some illnesses (e.g., cancer and heart disease) for which the number of research projects funded deviated from our expectations, given their disease burden. Our findings suggest several possibilities for future studies that would serve to further inform the allocation of limited research dollars within the field of biomedical engineering.

    African Americans are less likely than European Americans to participate in biomedical research. Researchers often attribute nonparticipation to the "Tuskegee effect." Using critical qualitative analysis of focus group data, we examined the public's use of the Tuskegee Study of Untreated Syphilis (TSUS) to discuss biomedical research. Our participants articulated three primary themes in relation to TSUS: 1) that TSUS made them suspicious about biomedical research; 2) that other values had to weigh against concerns about TSUS; and 3) that African Americans could take steps to resolve their concerns about TSUS. African Americans were more likely to discuss TSUS than were European Americans. African Americans did not use TSUS to express simple fear. African Americans suggested issues other than TSUS that influence the decision to participate in research. African Americans indicated specific reforms that would increase participation in research. We discuss how a better understanding of African Americans' use of TSUS can enhance research participation and allay concerns about "another Tuskegee." PMID:15303410

    Despite the dramatic increase in human lifespan over the past century, there remains pronounced variability in "health-span," or the period of time in which one is generally healthy and free of disease. Much of the variability in health-span and lifespan is thought to be genetic in origin. Understanding the genetic mechanisms of aging and identifying ways to boost longevity is a primary goal in aging research. Here, we describe a pipeline of phenotypic assays for assessing mouse models of aging. This pipeline includes behavior/cognition testing, body composition analysis, and tests of kidney function, hematopoiesis, and immune function, as well as physical parameters. We also describe study design methods for assessing lifespan and health-span, and other important considerations when conducting aging research in the laboratory mouse. The tools and assays provided can assist researchers with understanding the correlative relationships between age-associated phenotypes and, ultimately, the role of specific genes in the aging process.

    Despite the dramatic increase in human lifespan over the past century, there remains pronounced variability in “health-span”, or the period of time in which one is generally healthy and free of disease. Much of the variability in health-span and lifespan is thought to be genetic in origin. Understanding the genetic mechanisms of aging and identifying ways to boost longevity is a primary goal in aging research. Here, we describe a pipeline of phenotypic assays for assessing mouse models of aging. This pipeline includes behavior/cognition testing, body composition analysis, and tests of kidney function, hematopoiesis, immune function and physical parameters. We also describe study design methods for assessing lifespan and health-span, and other important considerations when conducting aging research in the laboratory mouse. The tools and assays provided can assist researchers with understanding the correlative relationships between age-associated phenotypes and, ultimately, the role of specific genes in the aging process.

    Objective The amount of information for clinicians and clinical researchers is growing exponentially. Text summarization reduces information as an attempt to enable users to find and understand relevant source texts more quickly and effortlessly. In recent years, substantial research has been conducted to develop and evaluate various summarization techniques in the biomedical domain. The goal of this study was to systematically review recent published research on summarization of textual documents in the biomedical domain. Materials and methods MEDLINE (2000 to October 2013), IEEE Digital Library, and the ACM Digital library were searched. Investigators independently screened and abstracted studies that examined text summarization techniques in the biomedical domain. Information is derived from selected articles on five dimensions: input, purpose, output, method and evaluation. Results Of 10,786 studies retrieved, 34 (0.3%) met the inclusion criteria. Natural Language processing (17; 50%) and a Hybrid technique comprising of statistical, Natural language processing and machine learning (15; 44%) were the most common summarization approaches. Most studies (28; 82%) conducted an intrinsic evaluation. Discussion This is the first systematic review of text summarization in the biomedical domain. The study identified research gaps and provides recommendations for guiding future research on biomedical text summarization. conclusion Recent research has focused on a Hybrid technique comprising statistical, language processing and machine learning techniques. Further research is needed on the application and evaluation of text summarization in real research or patient care settings. PMID:25016293

    The worldwide adoption of electronic health records (EHR) promises to accelerate clinical research, which lies at the heart of medical advances. However, the interrogation of such Big Data by clinical researchers can be laborious and error-prone, involving iterative and ineffective communication of data requests to data analysts. Research on this communication process is rare. There also exists no contemporary system that offers intelligent solutions to assist clinical researchers in their quest for clinical data. In this article, we first provide a detailed characterization of the challenges encountered in this communication space. Second, we identify promising synergies between fields studying human-to-human and human-machine communication that can shed light on biomedical data query mediation. We propose a mixed-initiative dialog-based approach to support autonomous clinical data access and recommend needed technology development and communication study for accelerating clinical research.

  19. Acoustic separation and biomedical research: lessons from Indian regulation of compensation for research injury.

    PubMed

    Larkin, Megan E

    2015-01-01

    In early 2013, the Indian government introduced new rules governing the conduct of clinical trials involving human participants. Among other provisions, the law requires that sponsors of research compensate participants who are injured during the course of their research participation. This article examines the effects of India's compensation law and the efforts that policymakers in India have made to tailor the law since its passage. I use the legal concept of acoustic separation as a framework to explain and justify the approach that India has taken in refining its regulation of research related injuries. I conclude that India's example may provide useful lessons for research sponsors and lawmakers in other regulatory states seeking to promote a well-regulated biomedical research industry.

    Due to its complex nature, modern biomedical research has become increasingly interdisciplinary and collaborative in nature. Although a necessity, interdisciplinary biomedical collaboration is difficult. There is, however, a growing body of literature on the study and fostering of collaboration in fields such as computer supported cooperative work (CSCW) and information science (IS). These studies of collaboration provide insight into how to potentially alleviate the difficulties of interdisciplinary collaborative research. We, therefore, undertook a cross cutting study of science and engineering collaboratories to identify emergent themes. We review many relevant collaboratory concepts: (a) general collaboratory concepts across many domains: communication, common workspace and coordination, and data sharing and management, (b) specific collaboratory concepts of particular biomedical relevance: data integration and analysis, security structure, metadata and data provenance, and interoperability and data standards, (c) environmental factors that support collaboratories: administrative and management structure, technical support, and available funding as critical environmental factors, and (d) future considerations for biomedical collaboration: appropriate training and long-term planning. In our opinion, the collaboratory concepts we discuss can guide planning and design of future collaborative infrastructure by biomedical informatics researchers to alleviate some of the difficulties of interdisciplinary biomedical collaboration.

    In 1985, a letter of agreement was signed between the French space agency, CNES, and NASA, formally initiating a joint venture called the RHESUS Project. The goal of this project is to provide a facility to fly rhesus monkeys (Macaca mulatta) to support spaceflight experiments which are applicable but not practical to carry out on human subjects. Biomedical investigations in behavior/performance, immunology/microbiology, muscle physiology, cardiopulmonary physiology, bone/calcium physiology, regulatory physiology, and neurophysiology disciplines will be performed. The Rhesus Research Facility, hardware capable of supporting two adult rhesus monkeys in a microgravity environment, is being developed for a first flight on Spacelab Life Sciences in early 1996.

    2013-12-01

    Analyser-based imaging (ABI) is one of the several phase-contrast x-ray imaging techniques being pursued at synchrotron radiation facilities. With advancements in compact source technology, there is a possibility that ABI will become a clinical imaging modality. This paper presents the history of ABI as it has developed from its laboratory source to synchrotron imaging. The fundamental physics of phase-contrast imaging is presented both in a general sense and specifically for ABI. The technology is dependent on the use of perfect crystal monochromator optics. The theory of the x-ray optics is developed and presented in a way that will allow optimization of the imaging for specific biomedical systems. The advancement of analytical algorithms to produce separate images of the sample absorption, refraction angle map and small-angle x-ray scattering is detailed. Several detailed applications to biomedical imaging are presented to illustrate the broad range of systems and body sites studied preclinically to date: breast, cartilage and bone, soft tissue and organs. Ultimately, the application of ABI in clinical imaging will depend partly on the availability of compact sources with sufficient x-ray intensity comparable with that of the current synchrotron environment.

    The environment's contribution to health has been conceptualized as the exposome. Biomedical research interest in environmental exposures as a determinant of physiopathological processes is rising as such data increasingly become available. The panoply of miniaturized sensing devices now accessible and affordable for individuals to use to monitor a widening range of parameters opens up a new world of research data. Biomedical informatics (BMI) must provide a coherent framework for dealing with multi-scale population data including the phenome, the genome, the exposome, and their interconnections. The combination of these more continuous, comprehensive, and personalized data sources requires new research and development approaches to data management, analysis, and visualization. This article analyzes the implications of a new paradigm for the discipline of BMI, one that recognizes genome, phenome, and exposome data and their intricate interactions as the basis for biomedical research now and for clinical care in the near future.

  5. Increasing disparities between resource inputs and outcomes, as measured by certain health deliverables, in biomedical research.

    Society makes substantial investments in biomedical research, searching for ways to better human health. The product of this research is principally information published in scientific journals. Continued investment in science relies on society's confidence in the accuracy, honesty, and utility of research results. A recent focus on productivity has dominated the competitive evaluation of scientists, creating incentives to maximize publication numbers, citation counts, and publications in high-impact journals. Some studies have also suggested a decreasing quality in the published literature. The efficiency of society's investments in biomedical research, in terms of improved health outcomes, has not been studied. We show that biomedical research outcomes over the last five decades, as estimated by both life expectancy and New Molecular Entities approved by the Food and Drug Administration, have remained relatively constant despite rising resource inputs and scientific knowledge. Research investments by the National Institutes of Health over this time correlate with publication and author numbers but not with the numerical development of novel therapeutics. We consider several possibilities for the growing input-outcome disparity including the prior elimination of easier research questions, increasing specialization, overreliance on reductionism, a disproportionate emphasis on scientific outputs, and other negative pressures on the scientific enterprise. Monitoring the efficiency of research investments in producing positive societal outcomes may be a useful mechanism for weighing the efficacy of reforms to the scientific enterprise. Understanding the causes of the increasing input-outcome disparity in biomedical research may improve society's confidence in science and provide support for growing future research investments.

    Background: Biomedical publications from a country mirror the standard of Medical Education and practice in that country. It is important that the performance of the health profession is occasionally documented. Aims: This study aimed to analyze the quantity and quality of biomedical publications from the Kingdom of Saudi Arabia (KSA) in international journals indexed in PubMed between 2008 and 2012. Materials and Methods: PubMed was searched for publications associated with KSA from 2008 to 2012. The search was limited to medical and biomedical subjects. Results were saved in a text file and later checked carefully to exclude false positive errors. The quality of the publication was assessed using Journal Citation Report 2012. Results: Biomedical research production in KSA in those 5 years showed a clear linear progression. Riyadh was the main hub of medical and biomedical research activity. Most of the publications (40.9%) originated from King Saud University (KSU). About half of the articles were published in journals with an Impact Factor (IF) of < 1, one-fourth in journals with no IF, and the remaining one-fourth in journals with a high IF (≥1). Conclusion: This study revealed that research activity in KSA is increasing. However, there is an increasing trend of publishing in local journals with a low IF. More effort is required to promote medical research in Saudi Arabia. PMID:25657608

    98Emphasis on the individual investigator has fostered discovery for centuries, yet it is now recognized that the complexity of problems in the biomedical sciences and engineering requires collaborative efforts from individuals having diverse training and expertise. Various approaches can facilitate interdisciplinary interactions, but we submit that there is a critical need for a new educational paradigm for the way that we train biomedical engineers, life scientists, and mathematicians. We cannot continue to train graduate students in isolation within single disciplines, nor can we ask any one individual to learn all the essentials of biology, engineering, and mathematics. We must transform how students are trained and incorporate how real-world research and development are done-in diverse, interdisciplinary teams. Our fundamental vision is to create an innovative paradigm for graduate research and training that yields a new generation of biomedical engineers, life scientists, and mathematicians that is more diverse and that embraces and actively pursues a truly interdisciplinary, team-based approach to research based on a known benefit and mutual respect. In this paper, we describe our attempt to accomplish this via focused training in biomechanics, biomedical optics, mathematics, mechanobiology, and physiology. The overall approach is applicable, however, to most areas of biomedical research.

    An understanding of health beliefs is key to creating culturally appropriate health services for Hispanic populations in the US. In this study we explore age-based variations in causal beliefs for heart disease and diabetes among Mexican origin adults in Houston, TX. This cross-sectional study included 497 adults of Mexican origin. Participants were asked to indicate the importance of biomedically defined and folk illness-related risk factors as causes for heart disease and diabetes. Biomedical risk factors were ranked highest as causes of diabetes and heart disease among all participants. Folk illness-related factors were ranked below biomedical factors as causes of heart disease among all age groups. Susto was ranked above the median as a risk factor for diabetes among older participants. Age-related differences in causal beliefs may have implications for designing culturally appropriate health services, such as tailored diabetes interventions for older Mexican origin adults.

    Electrospinning has been exploited for almost one century to process polymers and related materials into nanofibers with controllable compositions, diameters, porosities, and porous structures for a variety of applications. Owing to its high porosity and large surface area, a non-woven mat of electrospun nanofibers can serve as an ideal scaffold to mimic the extracellular matrix for cell attachment and nutrient transportation. The nanofiber itself can also be functionalized through encapsulation or attachment of bioactive species such as extracellular matrix proteins, enzymes, and growth factors. In addition, the nanofibers can be further assembled into a variety of arrays or architectures by manipulating their alignment, stacking, or folding. All these attributes make electrospinning a powerful tool for generating nanostructured materials for a range of biomedical applications that include controlled release, drug delivery, and tissue engineering.

    The biomacromolecule, gelatin, has increasingly been used in biomedicine-beyond its traditional use in food and cosmetics. The appealing advantages of gelatin, such as its cell-adhesive structure, low cost, off-the-shelf availability, high biocompatibility, biodegradability and low immunogenicity, among others, have made it a desirable candidate for the development of biomaterials for tissue engineering and drug delivery. Gelatin can be formulated in the form of nanoparticles, employed as size-controllable porogen, adopted as surface coating agent and mixed with synthetic or natural biopolymers forming composite scaffolds. In this article, we review recent advances in the versatile applications of gelatin within biomedical context and attempt to draw upon its advantages and potential challenges.

    Miniaturized separation techniques have emerged as environmentally friendly alternatives to available separation methods. Nano-liquid chromatography (nano-LC), microchip devices and nano-capillary electrophoresis are miniaturized methods that minimize reagent consumption and waste generation. Furthermore, the low levels of analytes, especially in biological samples, promote the search for more highly sensitive techniques; coupled to mass spectrometry, nano-LC has great potential to become an indispensable tool for routine analysis of biomolecules. This short review presents the fundamental aspects of nano-LC analytical instrumentation, discussing practical considerations and the primary differences between miniaturized and conventional instrumentation. Some theoretical aspects are discussed to better explain both the potential and the principal limitations of nano-LC. Recent pharmaceutical and biomedical applications of this separation technique are also presented to indicate the satisfactory performance for complex matrices, especially for proteomic analysis, that is obtained with nano-LC.

    During the past two decades, Iran has experienced a noteworthy growth in its biomedical research sector. At the same time, ethical concerns and debates resulting from this burgeoning enterprise has led to increasing attention paid to biomedical ethics. In Iran, Biomedical research ethics and research oversight passed through major periods during the past decades, separated by a paradigm shift. Period 1, starting from the early 1970s, is characterized by research paternalism and complete reliance on researchers as virtuous and caring physicians. This approach was in concordance with the paternalistic clinical practice of physicians outside of research settings during the same period. Period 2, starting from the late 1990s, was partly due to revealing of ethical flaws that occurred in biomedical research in Iran. The regulatory and funding bodies concluded that it was not sufficient to rely solely on the personal and professional virtues of researchers to safeguard human subjects' rights and welfare. The necessity for independent oversight, emphasized by international declarations, became obvious and undeniable. This paradigm shift led to the establishment of research ethics committees throughout the country, the establishment of academic research centers focusing on medical ethics (MEHR) and the compilation of the first set of national ethical guidelines on biomedical research-one of the first and most important projects conducted by and in the MEHR. Although not yet arrived, 'period 3' is on its way. It is predictable from the obvious trends toward performance of high-quality clinical research and the appearance of a highly educated new generation, especially among women.

    During the last 50-60 years, due to development of medical care and hygienically safe living conditions, the average life span of European citizens has substantially increased, with a rapid growth of the population older than 65 years. This trend places ever-growing medical and economical burden on society, as many of the older subjects suffer from age-related diseases and frailty. Coping with these problems requires not only appropriate medical treatment and social support but also extensive research in many fields of aging-from biology to sociology, with involvement of older people as the research subjects. This work anticipates development and application of ethical standards suited to dynamic advances in aging research. The aim of this review is to update the knowledge in ethical requirements toward recruitment of older research subjects, obtaining of informed consent, collection of biological samples, and use of stem cells in preclinical and clinical settings. It is concluded that application of adequate ethical platform markedly facilitates recruitment of older persons for participation in research. Currently, the basic ethical concepts are subjected to extensive discussion, with participation of all interested parties, in order to guarantee successful research on problems of human aging, protect older people from undesired interference, and afford their benefits through supporting innovations in research, therapy, and care.

    Recent years have seen tremendous changes in the modes of publication and dissemination of biomedical information, with the introduction of countless new publishers and publishing models, as well as alternative modes of research evaluation. In parallel, we are witnessing an unsustainable explosion in the amount of information generated by each individual scientist, at the same time as many countries' shrinking research budgets are greatly increasing the competition for research funding. In such a hypercompetitive environment, how does one measure excellence? This contribution will provide an overview of some of the ongoing changes in authorship practices in the biomedical sciences, and also the consequences of hypercompetition to the careers of young scientists, from the perspective of a tenured young faculty member in the biomedical sciences. It will also provide some suggestions as to alternate dissemination and evaluation practices that could reverse current trends. [Int Microbiol 18(4):253-261 (2015)].

    We examine effects of government spending on postdoctoral researchers' (postdocs) productivity in biomedical sciences, the largest population of postdocs in the US. We analyze changes in the productivity of postdocs before and after the US government's 1997 decision to increase NIH funding. In the first round of analysis, we find that more government spending has resulted in longer postdoc careers. We see no significant changes in researchers' productivity in terms of publication and conference presentations. However, when the population is segmented by citizenship, we find that the effects are heterogeneous; US citizens stay longer in postdoc positions with no change in publications and, in contrast, international permanent residents (green card holders) produce more conference papers and publications without significant changes in postdoc duration. Possible explanations and policy implications of the analysis are discussed.

    White matter hyperintense lesions on T2-weighted images are associated with late-life depression. Little work has been carried out examining differences in lesion location between elderly individuals with and without depression. In contrast to previous studies examining total brain white matter lesion volume, this study examined lobar differences in white matter lesion volumes derived from brain magnetic resonance imaging. This study examined 49 subjects with a DSM-IV diagnosis of major depression and 50 comparison subjects without depression. All participants were age 60 years or older. White matter lesion volumes were measured in each hemisphere using a semiautomated segmentation process and localized to lobar regions using a lobar atlas created for this sample using the imaging tools provided by the Biomedical Informatics Research Network (BIRN). The lobar lesion volumes were compared against depression status. After controlling for age and hypertension, subjects with depression exhibited significantly greater total white matter lesion volume in both hemispheres and in both frontal lobes than did control subjects. Although a similar trend was observed in the parietal lobes, the difference did not reach a level of statistical significance. Models of the temporal and occipital lobes were not statistically significant. Older individuals with depression have greater white matter disease than healthy controls, predominantly in the frontal lobes. These changes are thought to disrupt neural circuits involved in mood regulation, thus increasing the risk of developing depression.

    2012-07-01

    The U.S. biomedical research community finds itself at a particularly consequential moment. Since the end of the Fiscal Year (FY) 1998-2003 NIH budget doubling period, brought to fruition with bipartisan leadership, the Federal investment in biomedical research has been declining. The NIH budget has actually decreased in constant dollars since FY 2004. Across-the-board cuts included in the Budget Control Act of 2011 would result in a loss of $2.4 billion and roughly 2,300 research project grants in FY 2013 alone, unless Congress acts to intervene before January 2013. Many of the beneficiaries of NIH support view advocacy for research funding as "someone else's job". The case to reverse this mindset must be made. Members of Congress and their staffers are open to consideration of the case for sustaining Federal investments in science, even during these difficult budget times. However, the advocacy effort must be broad-based and repeatedly presented to effect change. The figures on economic return from spending on biomedical research are compelling, but they do not tell the entire story. The results of biomedical research improve and save lives every single day, a fact that should not be lost on our elected leaders.

    The present paper is to evaluate the scientific research level and development trends of biomedical engineering in China using metrology analysis on Chinese biomedical engineering scientific literatures. Pubmed is used to search the biomedical engineering publications in recent 5 years which are indexed by Science Citation Index, and the number and cited times of these publications and the impact factor of the journals are analyzed. The results show that comparing with the world, although the number of the publication in China has increased in recent 5 years, there is still much room for improvement. Among Chinese mainland, Hongkong and Taiwan, Chinese mainland maintains the obvious advantage in this subject, but Hongkong has the highest average cited number. Shanghai and Beijing have better research ability than other areas in Chinese mainland.

    Biomedical Informatics is a new discipline that arose from the need to incorporate information technologies to the generation, storage, distribution and analysis of information in the domain of biomedical sciences. This discipline comprises basic biomedical informatics, and public health informatics. The development of the discipline in Chile has been modest and most projects have originated from the interest of individual people or institutions, without a systematic and coordinated national development. Considering the unique features of health care system of our country, research in the area of biomedical informatics is becoming an imperative.

    Nanocellulose materials are nano-sized cellulose fibers or crystals that are produced by bacteria or derived from plants. These materials exhibit exceptional strength characteristics, light weight, transparency, and excellent biocompatibility. Compared to some other nanomaterials, nanocellulose is renewable and less expensive to produce. As such, a wide range of applications for nanocellulose has been envisioned. Most extensively studied areas include polymer composites and biomedical applications. Cellulose nanofibrils and nanocrystals have been used to reinforce both thermoplastic and thermoset polymers. Given the hydrophilic nature of these materials, the interfacial properties with most polymers are often poor. Various surface modification procedures have thus been adopted to improve the interaction between polymer matrix and cellulose nanofibrils or nanocrystals. In addition, the applications of nanocellulose as biomaterials have been explored including wound dressing, tissue repair, and medical implants. Nanocellulose materials for wound healing and periodontal tissue recovery have become commercially available, demonstrating the great potential of nanocellulose as a new generation of biomaterials. In this review, we highlight the applications of nanocellulose as reinforcing fillers for composites and the effect of surface modification on the mechanical properties as well as the application as biomaterials.

  6. Bayes' theorem: a paradigm research tool in biomedical sciences.

    One of the most interesting applications of the results of probability theory involves estimating unknown probability and making decisions on the basis of new (sample) information. Biomedical scientists often use the Bayesian decision theory for the purposes of computing diagnostic values such as sensitivity and specificity for a certain diagnostic test and from which positive or negative predictive values are obtained in other to make decisions concerning the well-being of the patient. Often times error rates are encountered and estimated from the results of trials of the screening test with a view to calculating the overall case rate for which an accurate estimate is rarely available. The concept of conditional probability takes into account information about the occurrence of one event to predict the probability of another event. It is on this premise that this article presents Bayes' theorem as a vital tool. A brief intuitive development of this theorem and its application in diagnosis is given with minimum proof and examples.

    There is a growing movement to encourage reproducibility and transparency practices in the scientific community, including public access to raw data and protocols, the conduct of replication studies, systematic integration of evidence in systematic reviews, and the documentation of funding and potential conflicts of interest. In this survey, we assessed the current status of reproducibility and transparency addressing these indicators in a random sample of 441 biomedical journal articles published in 2000–2014. Only one study provided a full protocol and none made all raw data directly available. Replication studies were rare (n = 4), and only 16 studies had their data included in a subsequent systematic review or meta-analysis. The majority of studies did not mention anything about funding or conflicts of interest. The percentage of articles with no statement of conflict decreased substantially between 2000 and 2014 (94.4% in 2000 to 34.6% in 2014); the percentage of articles reporting statements of conflicts (0% in 2000, 15.4% in 2014) or no conflicts (5.6% in 2000, 50.0% in 2014) increased. Articles published in journals in the clinical medicine category versus other fields were almost twice as likely to not include any information on funding and to have private funding. This study provides baseline data to compare future progress in improving these indicators in the scientific literature. PMID:26726926

  8. Guidelines for Developing and Reporting Machine Learning Predictive Models in Biomedical Research: A Multidisciplinary View

    2016-01-01

    Background As more and more researchers are turning to big data for new opportunities of biomedical discoveries, machine learning models, as the backbone of big data analysis, are mentioned more often in biomedical journals. However, owing to the inherent complexity of machine learning methods, they are prone to misuse. Because of the flexibility in specifying machine learning models, the results are often insufficiently reported in research articles, hindering reliable assessment of model validity and consistent interpretation of model outputs. Objective To attain a set of guidelines on the use of machine learning predictive models within clinical settings to make sure the models are correctly applied and sufficiently reported so that true discoveries can be distinguished from random coincidence. Methods A multidisciplinary panel of machine learning experts, clinicians, and traditional statisticians were interviewed, using an iterative process in accordance with the Delphi method. Results The process produced a set of guidelines that consists of (1) a list of reporting items to be included in a research article and (2) a set of practical sequential steps for developing predictive models. Conclusions A set of guidelines was generated to enable correct application of machine learning models and consistent reporting of model specifications and results in biomedical research. We believe that such guidelines will accelerate the adoption of big data analysis, particularly with machine learning methods, in the biomedical research community. PMID:27986644

    In recent years, increasing interest in using the pig (Sus scrofa) for biomedical research has become evident. Today, the pig is considered an advantageous alternative animal model for various human diseases and conditions. However, even though a considerable amount of biomedical research has been done on pigs, hardly any studies include systematic welfare assessment. Still, it is essential to assess welfare of laboratory pigs, both domestic pig breeds and smaller purpose-bred breeds, as (1) scientific obligations entail responsibility to ensure and document a fair welfare standard for animals used for experimental purposes; and (2) the scientific outcome can be dependent upon the welfare state of the animals. In order to be able to quantify and control laboratory pig welfare, a practical tool is needed. The purpose of the present paper is to provide an overview of the current status of the extent of welfare assessment in pigs used in biomedical research and to suggest a welfare assessment standard for research facilities based on an exposition of ethological considerations relevant for the welfare of pigs in biomedical research. The tools for porcine welfare assessment presented suggest a method for monitoring the welfare status of individual laboratory pigs, intended to relieve the practical scoring of the welfare of individual pigs as well as the interpretation of the findings.

    Objective A mixed methods study exploring the UK general public's willingness to donate human biosamples (HBSs) for biomedical research. Setting Cross-sectional focus groups followed by an online survey. Participants Twelve focus groups (81 participants) selectively sampled to reflect a range of demographic groups; 1110 survey responders recruited through a stratified sampling method with quotas set on sex, age, geographical location, socioeconomic group and ethnicity. Main outcome measures (1) Identify participants’ willingness to donate HBSs for biomedical research, (2) explore acceptability towards donating different types of HBSs in various settings and (3) explore preferences regarding use and access to HBSs. Results 87% of survey participants thought donation of HBSs was important and 75% wanted to be asked to donate in general. Responders who self-reported having some or good knowledge of the medical research process were significantly more likely to want to donate (p<0.001). Reasons why focus group participants saw donation as important included: it was a good way of reciprocating for the medical treatment received; it was an important way of developing drugs and treatments; residual tissue would otherwise go to waste and they or their family members might benefit. The most controversial types of HBSs to donate included: brain post mortem (29% would donate), eyes post mortem (35%), embryos (44%), spare eggs (48%) and sperm (58%). Regarding the use of samples, there were concerns over animal research (34%), research conducted outside the UK (35%), and research conducted by pharmaceutical companies (56%), although education and discussion were found to alleviate such concerns. Conclusions There is a high level of public support and willingness to donate HBSs for biomedical research. Underlying concerns exist regarding the use of certain types of HBSs and conditions under which they are used. Improved education and more controlled forms of consent for

    Women and people of color continue to be underrepresented among biomedical researchers to an alarming degree. Research interest and subsequent productivity have been shown to be affected by the research training environment through the mediating effects of research self-efficacy. This article presents the findings of a study to determine whether a short-term research training program coupled with an efficacy enhancing intervention for novice female biomedical scientists of diverse racial backgrounds would increase their research self-efficacy beliefs. Forty-three female biomedical scientists were randomized into a control or intervention group and 15 men participated as a control group. Research self-efficacy significantly increased for women who participated in the self-efficacy intervention workshop. Research self-efficacy within each group also significantly increased following the short-term research training program, but cross-group comparisons were not significant. These findings suggest that educational interventions that target sources of self-efficacy and provide domain-specific learning experiences are effective at increasing research self-efficacy for women and men. Further studies are needed to determine the longitudinal outcomes of this effort.

    The experimental use of non-human primates (NHP) in Europe is tightly regulated and is only permitted when there are no alternatives available. As a result, NHP are most often used in late, pre-clinical phases of biomedical research. Although the impetus for scientists, politicians and the general public to replace, reduce and refine NHP in biomedical research is strong, the development of 3Rs technology for NHP poses specific challenges. In February 2014 a workshop on "Alternative methods for the use of NHP in biomedical research" was organized within the international exchange program of EUPRIM-Net II, a European infrastructure initiative that links biomedical primate research centers. The workshop included lectures by key scientists in the field of alternatives as well as by experts from governmental and non-governmental organizations. Furthermore, parallel sessions were organized to stimulate discussion on the challenges of advancing the use of alternative methods for NHP. Subgroups voted on four statements and together composed a list with opportunities and priorities. This report summarizes the presentations that were held, the content of the discussion sessions and concludes with recommendations on 3Rs development for NHP specifically. These include technical, conceptual as well as political topics.

    Biomedical journals must adhere to strict standards of editorial quality. In a globalized academic scenario, biomedical journals must compete firstly to publish the most relevant original research and secondly to obtain the broadest possible visibility and the widest dissemination of their scientific contents. The cornerstone of the scientific process is still the peer-review system but additional quality criteria should be met. Recently access to medical information has been revolutionized by electronic editions. Bibliometric databases such as MEDLINE, the ISI Web of Science and Scopus offer comprehensive online information on medical literature. Classically, the prestige of biomedical journals has been measured by their impact factor but, recently, other indicators such as SCImago SJR or the Eigenfactor are emerging as alternative indices of a journal's quality. Assessing the scholarly impact of research and the merits of individual scientists remains a major challenge. Allocation of authorship credit also remains controversial. Furthermore, in our Kafkaesque world, we prefer to count rather than read the articles we judge. Quantitative publication metrics (research output) and citations analyses (scientific influence) are key determinants of the scientific success of individual investigators. However, academia is embracing new objective indicators (such as the "h" index) to evaluate scholarly merit. The present review discusses some editorial issues affecting biomedical journals, currently available bibliometric databases, bibliometric indices of journal quality and, finally, indicators of research performance and scientific success.

    The National Association of Physicians for the Environment (NAPE) has assumed a leadership role in protecting environmental health in recent years. The Committee of Biomedical Research Leaders was convened at the recent NAPE Leadership Conference: Biomedical Research and the Environment held on 1--2 November 1999, at the National Institutes of Health, Bethesda, Maryland. This report summarizes the discussion of the committee and its recommendations. The charge to the committee was to raise and address issues that will promote and sustain environmental health, safety, and energy efficiency within the biomedical community. Leaders from every important research sector (industry laboratories, academic health centers and institutes, hospitals and care facilities, Federal laboratories, and community-based research facilities) were gathered in this committee to discuss issues relevant to promoting environmental health. The conference and this report focus on the themes of environmental stewardship, sustainable development and "best greening practices." Environmental stewardship, an emerging theme within and outside the biomedical community, symbolizes the effort to provide an integrated, synthesized, and concerted effort to protect the health of the environment in both the present and the future. The primary goal established by the committee is to promote environmentally responsible leadership in the biomedical research community. Key outcomes of the committee's discussion and deliberation were a) the need for a central organization to evaluate, promote, and oversee efforts in environmental stewardship; and b) immediate need to facilitate efficient information transfer relevant to protecting the global environment through a database/clearinghouse. Means to fulfill these needs are discussed in this report. PMID:11121363

    2015-01-01

    Society makes substantial investments in biomedical research, searching for ways to better human health. The product of this research is principally information published in scientific journals. Continued investment in science relies on society’s confidence in the accuracy, honesty, and utility of research results. A recent focus on productivity has dominated the competitive evaluation of scientists, creating incentives to maximize publication numbers, citation counts, and publications in high-impact journals. Some studies have also suggested a decreasing quality in the published literature. The efficiency of society’s investments in biomedical research, in terms of improved health outcomes, has not been studied. We show that biomedical research outcomes over the last five decades, as estimated by both life expectancy and New Molecular Entities approved by the Food and Drug Administration, have remained relatively constant despite rising resource inputs and scientific knowledge. Research investments by the National Institutes of Health over this time correlate with publication and author numbers but not with the numerical development of novel therapeutics. We consider several possibilities for the growing input-outcome disparity including the prior elimination of easier research questions, increasing specialization, overreliance on reductionism, a disproportionate emphasis on scientific outputs, and other negative pressures on the scientific enterprise. Monitoring the efficiency of research investments in producing positive societal outcomes may be a useful mechanism for weighing the efficacy of reforms to the scientific enterprise. Understanding the causes of the increasing input-outcome disparity in biomedical research may improve society’s confidence in science and provide support for growing future research investments.

    Pharmaceutical human biomedical research is a multi-dimensional endeavor that requires collaboration among many parties, including those who sponsor, conduct, participate in, or stand to benefit from the research. Human subjects' protections have been promulgated to ensure that the benefits of such research are accomplished with respect for and minimal risk to individual research participants, and with an overall sense of fairness. Although these protections are foundational to clinical research, most ethics guidance primarily highlights the responsibilities of investigators and ethics review boards. Currently, there is no published resource that comprehensively addresses bioethical responsibilities of industry sponsors; including their responsibilities to parties who are not research participants, but are, nevertheless key stakeholders in the endeavor. To fill this void, in 2010 Eli Lilly and Company instituted a Bioethics Framework for Human Biomedical Research. This paper describes how the framework was developed and implemented and provides a critique based on four years of experience. A companion article provides the actual document used by Eli Lilly and Company to guide ethical decisions regarding all phases of human clinical trials. While many of the concepts presented in this framework are not novel, compiling them in a manner that articulates the ethical responsibilities of a sponsor is novel. By utilizing this type of bioethics framework, we have been able to develop bioethics positions on various topics, provide research ethics consultations, and integrate bioethics into the daily operations of our human biomedical research. We hope that by sharing these companion papers we will stimulate discussion within and outside the biopharmaceutical industry for the benefit of the multiple parties involved in pharmaceutical human biomedical research.

    Vervets, also known as African green monkeys, are a nonhuman primate species widely used in biomedical research. However, there are currently few references available describing techniques and rates of success for pair-housing this species. We present data from four cohorts of vervets from three different facilities: (i) the Wake Forest Vervet Research Colony (VRC; n = 72 female pairs, n = 52 male pairs), (ii) the University of Louisiana at Lafayette—New Iberia Research Center (UL-NIRC; n = 57 female pairs, n = 54 male pairs), (iii) the Tulane National Primate Research Center (TNRPC; n = 18 male pairs), and (iv) a cohort of imported males (n = 18 pairs) at Wake Forest. Compatibility was measured at 14, 30, and 60 days following introduction. Success rates for pair-housing at14 days ranged from 96% to 98% for females and 96% to 100% for males at the VRC and UL-NIRC but were lower in the smaller imported male cohorts (TNPRC: 50%; WF: 28%). Among the UL-NIRC cohort and VRC male cohort, most of the pair separations after 14 days were due to reasons unrelated to social incompatibility. In contrast, a large proportion of TNPRC and imported male pairs successful at 14 days required separation within 60 days due to incompatibility. Multiple logistic regressions were performed using cohort, mean age of pair and weight difference between pair-mates as potential predictors of compatibility at 14 days. All three predicted the 14-day outcome in males but not females. A separate analysis in the VRC cohort found no evidence that prior familiarity in a group setting influenced outcomes. Variations in success rates across cohorts may have been influenced by introduction methodology. Behavioral differences between vervets and macaques, coupled with our findings, lead us to theorize that the gradual introduction techniques commonly implemented to pair house macaques may not be beneficial or suitable for this species.

    Summary Cancer research involves numerous disciplines. The multiplicity of data sources and their heterogeneous nature render the integration and the exploration of the data more and more complex. Translational research platforms are a promising way to assist scientists in these tasks. In this article, we identify a set of scientific and technical principles needed to build a translational research platform compatible with ethical requirements, data protection and data-integration problems. We describe the solution adopted by the CARPEM cancer research program to design and deploy a platform able to integrate retrospective, prospective, and day-to-day care data. We designed a three-layer architecture composed of a data collection layer, a data integration layer and a data access layer. We leverage a set of open-source resources including i2b2 and tranSMART.

    Aquarium fishes are becoming increasingly important because of their value in biomedical research and the ornamental fish trade, and because many have become threatened or endangered in the wild. This review summarizes the current status of sperm cryopreservation in three fishes widely used in biomedical research: zebrafish, medaka, and live-bearing fishes of the genus Xiphophorus, and will focus on the needs and opportunities for future research and application of cryopreservation in aquarium fish. First, we summarize the basic biological characteristics regarding natural habitat, testis structure, spermatogenesis, sperm morphology, and sperm physiology. Second, we compare protocol development of sperm cryopreservation. Third, we emphasize the importance of artificial fertilization in sperm cryopreservation to evaluate the viability of thawed sperm. We conclude with a look to future research directions for sperm cryopreservation and the application of this technique in aquarium species. PMID:18691673

  13. Foundational biomedical informatics research in the clinical and translational science era: a call to action.

    Advances in clinical and translational science, along with related national-scale policy and funding mechanisms, have provided significant opportunities for the advancement of applied clinical research informatics (CRI) and translational bioinformatics (TBI). Such efforts are primarily oriented to application and infrastructure development and are critical to the conduct of clinical and translational research. However, they often come at the expense of the foundational CRI and TBI research needed to grow these important biomedical informatics subdisciplines and ensure future innovations. In light of this challenge, it is critical that a number of steps be taken, including the conduct of targeted advocacy campaigns, the development of community-accepted research agendas, and the continued creation of forums for collaboration and knowledge exchange. Such efforts are needed to ensure that the biomedical informatics community is able to advance CRI and TBI science in the context of the modern clinical and translational science era.

  14. An overview of nonhuman primates in aging research.

    A graying human population and the rising costs of healthcare have fueled the growing need for a sophisticated translational model of aging. Nonhuman primates (NHPs) experience aging processes similar to humans and, as a result, provide an excellent opportunity to study a closely related species. Rhesus monkeys share >92% homology and are the most commonly studied NHP. However, their substantial size, long lifespan, and the associated expense are prohibitive factors. Marmosets are rapidly becoming the preferred NHP for biomedical testing due to their small size, low zoonotic risk, reproductive efficiency, and relatively low-cost. Both species experience age-related pathology similar to humans, such as cancer, diabetes, arthritis, cardiovascular disease, and neurological decline. As a result, their use in aging research is paving the way to improved human health through a better understanding of the mechanisms of aging.

    In 2006, the New England Journal of Medicine selected medical imaging as one of the eleven most important innovations of the past 1,000 years, primarily due to its ability to allow physicians and researchers to visualize the very nature of disease. As a result of the broad-based adoption of micro imaging technologies, preclinical researchers today are generating terabytes of image data from both anatomic and functional imaging modes. In this paper we describe our early research to apply content-based image retrieval to index and manage large image libraries generated in the study of amyloid disease in mice. Amyloidosis is associated with diseases such as Alzheimer's, type 2 diabetes, and myeloma. In particular, we will focus on results to date in the area of small animal organ segmentation and description for CT, SPECT, and PET modes and present a small set of preliminary retrieval results for a specific disease state in kidney CT cross-sections.

  17. The use of nonhuman animals in biomedical research: necessity and justification.

    PubMed

    Francione, Gary L

    2007-01-01

    Discourse about the use of animals in biomedical research usually focuses on two issues: its empirical and moral use. The empirical issue asks whether the use of nonhumans in experiments is required in order to get data. The moral issue asks whether the use of nonhumans can be defended as matter of ethical theory. Although the use of animals in research may involve a plausible necessity claim, no moral justification exists for using nonhumans in situations in which we would not use humans.

    Microfluidics, a technology characterized by the engineered manipulation of fluids at the submillimetre scale, has shown considerable promise for improving diagnostics and biology research. Certain properties of microfluidic technologies, such as rapid sample processing and the precise control of fluids in an assay, have made them attractive candidates to replace traditional experimental approaches. Here we analyse the progress made by lab-on-a-chip microtechnologies in recent years, and discuss the clinical and research areas in which they have made the greatest impact. We also suggest directions that biologists, engineers and clinicians can take to help this technology live up to its potential.

    The social and medical costs of the biological aging process are high and will rise rapidly in coming decades, creating an enormous challenge to societies worldwide. In recent decades, researchers have expanded their understanding of the underlying deleterious structural and physiological changes (aging damage) that underlie the progressive functional impairments, declining health, and rising mortality of aging humans and other organisms and have been able to intervene in the process in model organisms, even late in life. To preempt a global aging crisis, we advocate an ambitious global initiative to translate these findings into interventions for aging humans, using three complementary approaches to retard, arrest, and even reverse aging damage, extending and even restoring the period of youthful health and functionality of older people.

    Obtaining effective informed consent from research participants is a prerequisite to the conduct of an ethically sound research. Yet it is believed that obtaining quality informed consent is generally difficult in settings with low socioeconomic status. This is so because of the alleged undue inducements and therapeutic misconception among participants. However, there is a dearth of data on factors that motivate research participants to take part in research. Hence, this study was aimed at filling this gap in the Malawian context. We conducted 18 focus group discussions with community members in urban and rural communities of Blantyre in Malawi. Most participants reported that they accepted the invitation to participate in research because of better quality treatment during study also known as ancillary care, monetary and material incentives given to participants, and thorough medical diagnosis.

    This article addresses current challenges facing pharmaceutical and biopharmaceutical developers, including the expiration of patents on many high revenue generating products, increasing competition of the marketplace, low public support, high regulatory hurdles, and the increasing time, cost, and risk of new product development. To meet these challenges, drug developers are looking to new models of innovation to improve efficiency, lower risk, and increase output. These new models include co-development agreements with small companies, multi-company consortia, and strategic partnerships with academic research centers. In the United States and the European Union, the government is supporting these efforts by creating incentives for academic centers to foster translational research and become more “commercially minded”. The goal for all stakeholders is to reduce the barriers to product development and bring new medicines to market in a timely and cost-efficient manner. PMID:22918200

    The DREADD (Designer Receptors Exclusively Activated by Designer Drugs) technique is a new chemogenetic approach allowing for selective and remote control of neural activity with a high degree of spatial resolution. Since its discovery in 2007 the DREADD technique was successfully employed into basic research, and together with the optogenetic method provided so far the best tool to influence the activity of the brain circuits and cell populations. The first aim of this review was to concisely describe the technique with regard to such issues like the history of its development, biochemistry as well as modes of the designer receptors delivery and expression. The other aim was to summarize approaches employed for probing of the brain circuits using the DREADD technique and to characterize the current knowledge of the method's application in medical research focusing on two diseases - Parkinson's disease and drug addiction - in which designer receptors were found notably valuable.

    Recent advances in molecular and cellular biology have facilitated the discovery of the key molecular drivers of major diseases. This knowledge raised some optimism in the beginning of this century, yet its impact on disease prevention, diagnosis and targeted intervention remains low. At the same time the pharmaceutical industry is facing the dual challenges of a dwindling drug pipeline and ever increasing cost of drug development. It is against this background that a number of European countries decided to establish EATRIS, the European Advanced Translational Research InfraStructure in Medicine. EATRIS aims for faster and more efficient translation of basic research into innovative products, by providing academia and industry access to the state-of-the-art expertise and highly capital-intensive facilities residing in Europe's top translational research centers and hospitals. To this end, EATRIS formed product groups that provide translational services in the fields of development and supply of (1) molecular imaging and tracing, (2) vaccines, (3) biomarkers, (4) small molecules and (5) advanced therapeutic medicinal products. Herein we describe the background, goals, functions and structure of EATRIS. As an example, it will be described how EATRIS centers involved in imaging and tracing might contribute to more efficient drug development and personalized medicine.

  12. Swine as models in biomedical research and toxicology testing.

    PubMed

    Swindle, M M; Makin, A; Herron, A J; Clubb, F J; Frazier, K S

    2012-03-01

    Swine are considered to be one of the major animal species used in translational research, surgical models, and procedural training and are increasingly being used as an alternative to the dog or monkey as the choice of nonrodent species in preclinical toxicologic testing of pharmaceuticals. There are unique advantages to the use of swine in this setting given that they share with humans similar anatomic and physiologic characteristics involving the cardiovascular, urinary, integumentary, and digestive systems. However, the investigator needs to be familiar with important anatomic, histopathologic, and clinicopathologic features of the laboratory pig and minipig in order to put background lesions or xenobiotically induced toxicologic changes in their proper perspective and also needs to consider specific anatomic differences when using the pig as a surgical model. Ethical considerations, as well as the existence of significant amounts of background data, from a regulatory perspective, provide further support for the use of this species in experimental or pharmaceutical research studies. It is likely that pigs and minipigs will become an increasingly important animal model for research and pharmaceutical development applications.

    The field of smart textile-based wearable biomedical systems (ST-WBSs) has of late been generating a lot of interest in the research and business communities since its early beginnings in the mid-nineties. However, the technology is yet to enter the marketplace and realize its original goal of enhancing the quality of life for individuals through enhanced real-time biomedical monitoring. In this paper, we propose a framework for analyzing the transition of ST-WBS from research to reality. We begin with a look at the evolution of the field and describe the major components of an ST-WBS. We then analyze the key issues encompassing the technical, medical, economic, public policy, and business facets from the viewpoints of various stakeholders in the continuum. We conclude with a plan of action for transitioning ST-WBS from "research to reality."

    OBJECTIVES: English has become the most frequently used language for scientific communication in the biomedical field. Therefore, scholars from all over the world try to publish their findings in English. This trend has a number of advantages, along with several disadvantages. METHODS: In the current article, the most important disadvantages of publishing biomedical research articles in English for non-native speakers of English are reviewed. RESULTS: The most important disadvantages of publishing biomedical research articles in English for non-native speakers may include: Overlooking, either unintentionally or even deliberately, the most important local health problems; failure to carry out groundbreaking research due to limited medical research budgets; violating generally accepted codes of publication ethics and committing research misconduct and publications in open-access scam/predatory journals rather than prestigious journals. CONCLUSIONS: The above mentioned disadvantages could eventually result in academic establishments becoming irresponsible or, even worse, corrupt. In order to avoid this, scientists, scientific organizations, academic institutions, and scientific associations all over the world should design and implement a wider range of collaborative and comprehensive plans.

    Motivations and decision-making styles that influence participation in biomedical research vary across study types, cultures, and countries. While there is a small amount of literature on informed consent in non-western cultures, few studies have examined how participants make the decision to join research. This study was designed to identify the factors motivating people to participate in biomedical research in a traditional Nigerian community, assess the degree to which participants involve others in the decision-making process, and examine issues of autonomy in decision-making for research. A descriptive cross-sectional study was conducted with 100 adults (50 men, 50 women) in an urban Nigerian community who had participated in a biomedical research study. Subjects were interviewed using a survey instrument. Two-thirds of the respondents reported participating in the biomedical study to learn more about their illness, while 30% hoped to get some medical care. Over three-quarters (78%) of participants discussed the enrolment decision with someone else and 39% reported obtaining permission from a spouse or family member to participate in the study. Women were more than twice as likely as men to report obtaining permission from someone else before participating. More specifically, half of the female participants reported seeking permission from a spouse before enrolling. The findings suggest that informed consent in this community is understood and practised as a relational activity that involves others in the decision making process. Further studies are needed in non-Western countries concerning autonomy, decision-making, and motivation to participate in research studies. PMID:22708614

    Statistics are the primary tools for assessing relationships and evaluating study questions. Unfortunately, these tools are often misused, either inadvertently because of ignorance or lack of planning, or conspicuously to achieve a specified result. Data abuses include the incorrect application of statistical tests, lack of transparency and disclosure about decisions that are made, incomplete or incorrect multivariate model building, or exclusion of outliers. Individually, each of these actions may completely invalidate a study, and often studies are victim to more than one offense. Increasingly there are tools and guidance for researchers to look to, including the development of an analysis plan and a series of study specific checklists, in order to prevent or mitigate these offenses.

Use of multivariable optimization yielded the highest weight savings possible while simultaneously matching NASA Human Standards nutritional guidelines. The scope of this research included the study of shelf-life indicators such as water activity, moisture content, and texture analysis. Key metrics indicate higher protein content, higher caloric density, and greater mass savings as a result of the reformulation process. The optimization performed for this study demonstrated wide application to other food bars in the Advanced Food Technology portfolio. Recommendations for future work include shelf life studies on bar hardening and overall acceptability data over increased time frames and temperature fluctuation scenarios.

The BBDTC collaborative is an e-learning platform that supports the biomedical community to access, develop and deploy open training materials. The BBDTC supports Big Data skill training for biomedical scientists at all levels, and from varied backgrounds. The natural hierarchy of courses allows them to be broken into and handled as modules. Modules can be reused in the context of multiple courses and reshuffled, producing a new and different, dynamic course called a playlist. Users may create playlists to suit their learning requirements and share it with individual users or the wider public. BBDTC leverages the maturity and design of the HUBzero content-management platform for delivering educational content. To facilitate the migration of existing content, the BBDTC supports importing and exporting course material from the edX platform. Migration tools will be extended in the future to support other platforms. Hands-on training software packages, i.e., toolboxes, are supported through Amazon EC2 and Virtualbox virtualization technologies, and they are available as: (i) downloadable lightweight Virtualbox Images providing a standardized software tool environment with software packages and test data on their personal machines, and (ii) remotely accessible Amazon EC2 Virtual Machines for accessing biomedical big data tools and scalable big data experiments.

    A well-attended meeting, called "Brainstorming discussion for a possible biomedical facility at CERN", was held by the European Organization for Nuclear Research (CERN) at the European Laboratory for Particle Physics on 25 June 2012. This was concerned with adapting an existing, but little used, 78-m circumference CERN synchrotron to deliver a wide range of ion species, preferably from protons to at least neon ions, with beam specifications that match existing clinical facilities. The potential extensive research portfolio discussed included beam ballistics in humanoid phantoms, advanced dosimetry, remote imaging techniques and technical developments in beam delivery, including gantry design. In addition, a modern laboratory for biomedical characterisation of these beams would allow important radiobiological studies, such as relative biological effectiveness, in a dedicated facility with standardisation of experimental conditions and biological end points. A control photon and electron beam would be required nearby for relative biological effectiveness comparisons. Research beam time availability would far exceed that at other facilities throughout the world. This would allow more rapid progress in several biomedical areas, such as in charged hadron therapy of cancer, radioisotope production and radioprotection. The ethos of CERN, in terms of open access, peer-reviewed projects and governance has been so successful for High Energy Physics that application of the same to biomedicine would attract high-quality research, with possible contributions from Europe and beyond, along with potential new funding streams.

    The aggregation of imaging, clinical, and behavioral data from multiple independent institutions and researchers presents both a great opportunity for biomedical research as well as a formidable challenge. Many research groups have wellestablished data collection and analysis procedures, as well as data and metadata format requirements that are particular to that group. Moreover, the types of data and metadata collected are quite diverse, including image, physiological, and behavioral data, as well as descriptions of experimental design, and preprocessing and analysis methods. Each of these types of data utilizes a variety of software tools for collection, storage, and processing. Furthermore sites are reluctant to release control over the distribution and access to the data and the tools. To address these needs, the Biomedical Informatics Research Network (BIRN) has developed a federated and distributed infrastructure for the storage, retrieval, analysis, and documentation of biomedical imaging data. The infrastructure consists of distributed data collections hosted on dedicated storage and computational resources located at each participating site, a federated data management system and data integration environment, an Extensible Markup Language (XML) schema for data exchange, and analysis pipelines, designed to leverage both the distributed data management environment and the available grid computing resources.

  6. An examination of how women and underrepresented racial/ethnic minorities experience barriers in biomedical research and medical programs

    NASA Astrophysics Data System (ADS)

    Chakraverty, Devasmita

    Women in medicine and biomedical research often face challenges to their retention, promotion, and advancement to leadership positions (McPhillips et al., 2007); they take longer to advance their careers, tend to serve at less research-intensive institutions and have shorter tenures compared to their male colleagues (White, McDade, Yamagata, & Morahan, 2012). Additionally, Blacks and Hispanics are the two largest minority groups that are vastly underrepresented in medicine and biomedical research in the United States (AAMC, 2012; NSF, 2011). The purpose of this study is to examine specific barriers reported by students and post-degree professionals in the field through the following questions: 1. How do women who are either currently enrolled or graduated from biomedical research or medical programs define and make meaning of gender-roles as academic barriers? 2. How do underrepresented groups in medical schools and biomedical research institutions define and make meaning of the academic barriers they face and the challenges these barriers pose to their success as individuals in the program? These questions were qualitatively analyzed using 146 interviews from Project TrEMUR applying grounded theory. Reported gender-role barriers were explained using the "Condition-Process-Outcome" theoretical framework. About one-third of the females (across all three programs; majority White or Black between 25-35 years of age) reported gender-role barriers, mostly due to poor mentoring, time constraints, set expectations and institutional barriers. Certain barriers act as conditions, causing gender-role issues, and gender-role issues influence certain barriers that act as outcomes. Strategies to overcome barriers included interventions mostly at the institutional level (mentor support, proper specialty selection, selecting academia over medicine). Barrier analysis for the two largest URM groups indicated that, while Blacks most frequently reported racism, gender barriers

    Low income Hispanic families experience multiple barriers to accessing evidence-based information on Autism Spectrum Disorders (ASD). This study utilized a mixed-strategy intervention to create access to information in published bio-medical research articles on ASD by distilling the content into parent-friendly English- and Spanish-language ASD Science Briefs and presenting them to participants using two socially-oriented dissemination methods. There was a main effect for short-term knowledge gains associated with the Science Briefs but no effect for the dissemination method. After 5 months, participants reported utilizing the information learned and 90% wanted to read more Science Briefs. These preliminary findings highlight the potential benefits of distilling biomedical research articles on ASD into parent-friendly educational products for currently underserved Hispanic parents.

    Animal experimentation contributes significantly to the progression of science. Nonhuman primates play a particularly important role in biomedical research not only because of their anatomical, physiological, biochemical, and behavioral similarities with humans but also because of their close phylogenetic affinities. In order to investigate the use of New World primates (NWP) in biomedical research over the last four decades (1966-2005), we performed a quantitative study of the literature listed in bibliographic databases from the Health Sciences. The survey was performed for each genus of NWP that has been bred in the National Center of Primates in Brazil. The number of articles published was determined for each genus and sorted according to the country from which the studies originated and the general scientific field. The data obtained suggests that Brazil is a leader in generating knowledge with NWP models for translational medicine.

    Next-generation sequencing technologies, microarrays and advances in bio nanotechnology have had an enormous impact on research within a short time frame. This impact appears certain to increase further as many biomedical institutions are now acquiring these prevailing new technologies. Beyond conventional sampling of genome content, wide-ranging applications are rapidly evolving for next-generation sequencing, microarrays and nanotechnology. To date, these technologies have been applied in a variety of contexts, including whole-genome sequencing, targeted re sequencing and discovery of transcription factor binding sites, noncoding RNA expression profiling and molecular diagnostics. This paper thus discusses current applications of nanotechnology, next-generation sequencing technologies and microarrays in biomedical research and highlights the transforming potential these technologies offer.

    Dealing with data from different source domains is of increasing importance in today's large scale biomedical research endeavours. Within the European Network for Cancer research in Children and Adolescents (ENCCA) a solution to share such data for secondary use will be established. In this paper the solution arising from the aims of the ENCCA project and regulatory requirements concerning data protection and privacy is presented. Since the details of secondary biomedical dataset utilisation are often not known in advance, data protection regulations are met with an identity management concept that facilitates context-specific pseudonymisation and a way of data aggregation using a hidden reference table later on. Phonetic hashing is proposed to prevent duplicated patient registration and re-identification of patients is possible via a trusted third party only. Finally, the solution architecture allows for implementation in a distributed computing environment, including cloud-based elements.

    The article explores and analyses the content of the Council of Europe's Additional Protocol to the Convention on Human Rights and Biomedicine concerning Biomedical Research regarding the standard legal instrument in biomedical research, issued by an international organization with leadership in bioethics. This implies ethics committees are mechanisms of protection of humans in biomedical research and not mere bureaucratic agencies and that a sound inescapable international regulatory framework exists for States to regulate biomedical research. The methodology used focuses on the analysis of the background, the context in which it is made and the nature and scope of the Protocol. It also identifies and analyses the characteristics and functions of ethics committees in biomedical research and, in particular, the information that should be provided to this bodies to develop their functions previously, during and at the end of research projects. This analysis will provide guidelines, suggestions and conclusions for the awareness and training of members of these committees in order to influence the daily practice. This paper may also be of interest to legal practitioners who work in different areas of biomedical research. From this practical perspective, the article examines the legal treatment of the Protocol to meet new challenges and classic issues in research: the treatment of human biological samples, the use of placebos, avoiding double standards, human vulnerability, undue influence and conflicts of interest, among others. Also, from a critical view, this work links the legal responses to develop work procedures that are required for an effective performance of the functions assigned of ethics committees in biomedical research. An existing international legal response that lacks doctrinal standards and provides little support should, however, serve as a guide and standard to develop actions that allow ethics committees -as key bodies for States- to advance in

    The vast availability of medical patient data in digital format creates the opportunity to use these data in medical informatics research projects. The objective is to improve future care by providing the medical staff with methods for automated data processing, including textual and visual information analysis and retrieval from medical databases. Many medical institutions do not possess a specific research computing infrastructure or the required budget for such an infrastructure to enable processing of these large amounts of data. Still, many institutions have many desktop PCs that could serve for biomedical research during the time they are little used without the need for expensive investments. The KnowARC project aims at building a middleware for such a simple-to-install Grid network. This article reviews requirements for computing Grids in large hospital environments. We use the computing infrastructure in the University Hospitals of Geneva as an example, and then present the solutions that the European Union-funded KnowARC project plans to undertake to solve the current problems. Methods currently employed in common Grid middleware distributions are also reviewed and assessed in relation to the goals of KnowARC. The computing infrastructure at the University Hospitals of Geneva is described as well as the needs and requirements for computing and storage services within this domain. A list of requirements for a Grid middleware to employ in such a challenging environment is developed. Finally, the proposed solutions and ideas of the KnowARC project are described in detail to present the project to a larger community. First proof of concept implementations and test results are described to illustrate how Grid networks are expected to become an important supplier of computational resources, which are required in several domains in biomedical research. A continuous process will be necessary to feed in the requirements of the biomedical domain to developers of

    Objective To develop software infrastructure that will provide support for discovery, characterization, integrated access, and management of diverse and disparate collections of information sources, analysis methods, and applications in biomedical research. Design An enterprise Grid software infrastructure, called caGrid version 1.0 (caGrid 1.0), has been developed as the core Grid architecture of the NCI-sponsored cancer Biomedical Informatics Grid (caBIG™) program. It is designed to support a wide range of use cases in basic, translational, and clinical research, including 1) discovery, 2) integrated and large-scale data analysis, and 3) coordinated study. Measurements The caGrid is built as a Grid software infrastructure and leverages Grid computing technologies and the Web Services Resource Framework standards. It provides a set of core services, toolkits for the development and deployment of new community provided services, and application programming interfaces for building client applications. Results The caGrid 1.0 was released to the caBIG community in December 2006. It is built on open source components and caGrid source code is publicly and freely available under a liberal open source license. The core software, associated tools, and documentation can be downloaded from the following URL: https://cabig.nci.nih.gov/workspaces/Architecture/caGrid. Conclusions While caGrid 1.0 is designed to address use cases in cancer research, the requirements associated with discovery, analysis and integration of large scale data, and coordinated studies are common in other biomedical fields. In this respect, caGrid 1.0 is the realization of a framework that can benefit the entire biomedical community. PMID:18096909

  17. Liberty to decide on dual use biomedical research: an acknowledged necessity.

    2010-03-01

    Humanity entered the twenty-first century with revolutionary achievements in biomedical research. At the same time multiple "dual-use" results have been published. The battle against infectious diseases is meeting new challenges, with newly emerging and re-emerging infections. Both natural disaster epidemics, such as SARS, avian influenza, haemorrhagic fevers, XDR and MDR tuberculosis and many others, and the possibility of intentional mis-use, such as letters containing anthrax spores in USA, 2001, have raised awareness of the real threats. Many great men, including Goethe, Spinoza, J.B. Shaw, Fr. Engels, J.F. Kennedy and others, have recognized that liberty is also a responsibility. That is why the liberty to decide now represents an acknowledged necessity: biomedical research should be supported, conducted and published with appropriate measures to prevent potential "dual use". Biomedical scientists should work according to the ethical principles of their Code of Conduct, an analogue of Hippocrates Oath of doctors; and they should inform government, society and their juniors about the problem. National science consulting boards of experts should be created to prepare guidelines and control the problem at state level. An international board should develop minimum standards to be applicable by each country. Bio-preparedness is considered another key-measure.

    This article specifically examines several aspects of the human-captive chimpanzee bond and the effort to create the first chimpanzee sanctuary in Japan. We discuss our ethical responsibility for captive chimpanzees that have been used in biomedical research. On April 1, 2007, the Chimpanzee Sanctuary Uto (CSU) was established as the first sanctuary for retired laboratory chimpanzees in Japan. This initiative was the result of the continuous efforts by members of Support for African/Asian Great Apes (SAGA), and the Great Ape Information Network to provide a solution to the large chimpanzee colony held in biomedical facilities. However, the cessation of invasive biomedical studies using chimpanzees has created a new set of challenges because Japan lacks registration and laws banning invasive ape experiments and lacks a national policy for the life-long care of retired laboratory chimpanzees. Therefore, CSU has initiated a relocation program in which 79 retired laboratory chimpanzees will be sent to domestic zoos and receive life-long care. By the end of 2009, the number of chimpanzees living at CSU had decreased from 79 to 59 individuals. A nationwide network of care facilities and CSU to provide life-long care of retired laboratory chimpanzees is growing across Japan. This will result in humane treatment of these research animals.

    Vervets, also known as African green monkeys, are a nonhuman primate species widely used in biomedical research. However, there are currently few references available describing techniques and rates of success for pair-housing this species. We present data from four cohorts of vervets from three different facilities: (i) the Wake Forest Vervet Research Colony (VRC; n = 72 female pairs, n= 52 male pairs), (ii) the University of Louisiana at Lafayette-New Iberia Research Center (UL-NIRC; n = 57 female pairs, n = 54 male pairs), (iii) the Tulane National Primate Research Center (TNRPC; n = 18 male pairs), and (iv) a cohort of imported males (n = 18 pairs) at Wake Forest. Compatibility was measured at 14, 30, and 60 days following introduction. Success rates for pair-housing at 14 days ranged from 96% to 98% for females and 96% to 100% for males at the VRC and UL-NIRC but were lower in the smaller imported male cohorts (TNPRC: 50%; WF: 28%). Among the UL-NIRC cohort and VRC male cohort, most of the pair separations after 14 days were due to reasons unrelated to social incompatibility. In contrast, a large proportion of TNPRC and imported male pairs successful at 14 days required separation within 60 days due to incompatibility. Multiple logistic regressions were performed using cohort, mean age of pair and weight difference between pair-mates as potential predictors of compatibility at 14 days. All three predicted the 14-day outcome in males but not females. A separate analysis in the VRC cohort found no evidence that prior familiarity in a group setting influenced outcomes. Variations in success rates across cohorts may have been influenced by introduction methodology. Behavioral differences between vervets and macaques, coupled with our findings, lead us to theorize that the gradual introduction techniques commonly implemented to pair house macaques may not be beneficial or suitable for this species.

    2010-01-01

    Lung cancer cell lines have made a substantial contribution to lung cancer translational research and biomedical discovery. A systematic approach to initiating and characterizing cell lines from small cell and non–small cell lung carcinomas has led to the current collection of more than 200 lung cancer cell lines, a number that exceeds those for other common epithelial cancers combined. The ready availability and widespread dissemination of the lines to investigators worldwide have resulted in more than 9000 citations, including multiple examples of important biomedical discoveries. The high (but not perfect) genomic similarities between lung cancer cell lines and the lung tumor type from which they were derived provide evidence of the relevance of their use. However, major problems including misidentification or cell line contamination remain. Ongoing studies and new approaches are expected to reveal the full potential of the lung cancer cell line panel.

    A model for an international undergraduate biomedical engineering research exchange program is outlined. In 2008, the Johns Hopkins University in collaboration with Tsinghua University in Beijing, China established the Tsinghua-Johns Hopkins Joint Center for Biomedical Engineering Research. Undergraduate biomedical engineering students from both universities are offered the opportunity to participate in research at the overseas institution. Programs such as these will not only provide research experiences for undergraduates but valuable cultural exchange and enrichment as well. Currently, strict course scheduling and rigorous curricula in most biomedical engineering programs may present obstacles for students to partake in study abroad opportunities. Universities are encouraged to harbor abroad opportunities for undergraduate engineering students, for which this particular program can serve as a model.

    The study of mouse genetics is a science in its own right. Currently, the mouse is the central platform for model building in biomedical research. Recombinant DNA technology and mouse transgenesis have provided an almost unlimited resource of new animals that is constantly expanding. Investigators, through their selection of the most appropriate type of mouse and by imaginative combinations of animals in breeding or culture experiments, have the opportunity for discovery of new information that will benefit the health of both humans and species of veterinary interest. Wider appreciation and use of the mouse as a discovery tool in veterinary research should be encouraged.

    2008-12-01

    This article aims to compare the national legal systems that regulate biomedical research in an industrialized country (United States) and a developing country (Venezuela). A new international order is emerging in which Europe, Japan and the United States (US) are revising common guidelines and harmonizing standards. In this article, we analyze - as an example - the US system. This system is controlled by a federal agency structured to regulate research funded by the federal government uniformly, either in the US or abroad. In contrast, in Venezuela, a developing country, the creation of a centralized system is a slow process. Different types of ethical committees review research projects using non-uniform criteria. Consequently, various parallel organizations that conduct biomedical research, such as universities, research institutes and private hospitals have diverse regulations operating at a local level. Thus, the most relevant difference between the Venezuelan and the US systems is the degree of standardization. In the US, the review process is performed by institutional review boards (IRBs), which have a similar organization and maintain relationships with a centralized agency, following standard regulations. Although new proposals for establishing national regulations are currently being considered in Venezuela, the success of these initiatives will depend on promoting governmental efforts to create a more structured centralized system supported by a national regulatory framework. This system will need governmental financial support at all levels. This article proposes an integrated system to regulate research with human participants in Venezuela and other developing countries.

    2015-04-01

    Rare diseases are rarely conditions that are often debilitating and even life-threatening, which was identified by the World Health Organization (WHO) with a prevalence of 0.65-1‰. 5,000-7,000 rare diseases are thought to exist, which account for around 10% of diseases for individuals worldwide. It is estimated that over 10 million people were patients with rare disease in China. During the past years, public awareness of rare diseases has in fact heightened with the launching of campaigns by patients' organizations and spontaneous efforts by members of the public, not only in developed countries and regions including United States of America (USA), the European Union (EU), and in Japan, but also in China. However, the features of missed or delayed diagnosis, shortage of effective drugs, and the high cost of currently available drugs for rare diseases make it an important public health issue and a challenge to medical care worldwide. To combat rare disease, the government should assume the responsibility of taking on the important task of promoting the sustained development of a system of medical care for and research into rare diseases. Government-funded special biomedical research programs in the USA, EU, and Japan may serve as a reference for China coping with rare diseases. The government-funded special biomedical research programs consisting of leading clinicians and researchers to enhance basic and applied research on rare diseases were expected to be launched in China.

    2003-06-06

    Combined chromatographic and mass spectrometric techniques and in particular liquid chromatography-mass spectrometry (LC-MS) have been contributing in a decisive way to the progress of life sciences in general. Thus, the number of document entries in the US National Library of Medicine (MEDLINE) for articles dealing with LC-MS was 738 in 1991 and 2285 in 2001, with a total of 13 147 for the whole 10-year period, an increase of 310%. From these figures, we can ascertain that the total usage of combined LC-MS techniques is of the order of 40% relative to all of the MS publications collected in MEDLINE for the same period. However, from the perspective of real advances in medicine, it becomes difficult to identify what is outstanding in this field. The aim of this review was not to provide another LC-MS review, but an overview of the current status of the presence, visibility and impact of combined LC-MS techniques in biomedical research. The idea being to spot "highlight" literature contributions with the potential to become in the short or medium term real assets in a doctor's daily medical practice. In other words, after several truly remarkable technical achievements reported within the past decade, are we any closer to making LC-MS a useful and practical diagnostic tool for molecular diagnostics and personalized medicine? To approach this question, a literature survey was carried out to define: (i) the presence of LC-MS in the biomedical literature (MEDLINE) and its weight relative to the whole field of biological and biomedical mass spectrometry; (ii) the role of LC-MS in recent milestone biomedical contributions; and (iii) the present and future role of new LC-MS technology in medical diagnosis.

Incomplete or inconsistent reporting may yield the published findings unreliable, irreproducible or sometimes misleading. In this study based on evidence from systematic reviews and surveys that have evaluated the reporting issues in primary biomedical studies, we aim to conduct a scoping review with focuses on (1) the state-of-the-art extent of adherence to the emerging reporting guidelines in primary biomedical research, (2) the inconsistency between protocols or registrations and full reports and (3) the disagreement between abstracts and full-text articles. Methods and analyses We will use a comprehensive search strategy to retrieve all available and eligible systematic reviews and surveys in the literature. We will search the following electronic databases: Web of Science, Excerpta Medica Database (EMBASE), MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL). Our outcomes are levels of adherence to reporting guidelines, levels of consistency between protocols or registrations and full reports and the agreement between abstracts and full reports, all of which will be expressed as percentages, quality scores or categorised rating (such as high, medium and low). No pooled analyses will be performed quantitatively given the heterogeneity of the included systematic reviews and surveys. Likewise, factors associated with improved completeness and consistency of reporting will be summarised qualitatively. The quality of the included systematic reviews will be evaluated using AMSTAR (a measurement tool to assess systematic reviews). Ethics and dissemination All findings will be published in peer-reviewed journals and relevant conferences. These results may advance our understanding of the extent of incomplete and inconsistent reporting, factors related to improved completeness and consistency of reporting and potential recommendations for

    DOE proposes to participate in the joint funding, along with the National Institutes of Health (NIH) and private donors, of a new biomedical cyclotron research instrument for UCLA. DOE proposes to provide funding in the amount of $500,000 to UCLA for removal and disposal of the existing 19 year old CS-22 cyclotron and refitting of the existing room, plus $900,000 (of the $1.5 million total cost) for installation of a new generation Cyclone 18/9 biomedical isotope compact cyclotron. The remaining $600,000 for the new instrument would be provided by NIH and private donors. The total cost for the entire project is $2,0000,000. Operation and use of the instrument would be entirely by UCLA. The Biomedical Cyclotron Facility is a line item included on UCLA's Broad Scope A License. The CS-22 cyclotron was turned over to UCLA's jurisdiction by DOE in 1989 when the Laboratory of Biomedical and Environmental Sciences General Contract with DOE was changed to a Cooperative Agreement, and Clause B'' involving safety responsibility was terminated. In support of this, a large closeout survey was performed, licensing actions were completed, and it was agreed that environmental, health and safety compliance would be UCLA's responsibility. Since the CS022 cyclotron was DOE property prior to the above changes, DOE proposes to provide this entire funding for its removal and disposal, and to provide partial funding for its replacement. This report describes the removal of the existing cyclotron, and the operation and installation of a new cyclotron as well as any associated environmental impacts.

    After identification of an important research question and selection of an appropriate study design, waste can arise from the regulation, governance, and management of biomedical research. Obtaining regulatory and governance approval has become increasingly burdensome and disproportionate to the conceivable risks to research participants. Regulation and governance involve interventions that are assumed to be justified in the interests of patients and the public, but they can actually compromise these interests. Inefficient management of the procedural conduct of research is wasteful, especially if it results in poor recruitment and retention of participants in well designed studies addressing important questions. These sources of waste can be minimised if the following four recommendations are addressed. First, regulators should use their influence to reduce other causes of waste and inefficiency in research. Second, regulators and policy makers should work with researchers, patients, and health professionals to streamline and harmonise the laws, regulations, guidelines, and processes that govern whether and how research can be done, and ensure that they are proportionate to the plausible risks associated with the research. Third, researchers and research managers should increase the efficiency of recruitment, retention, data monitoring, and data sharing in research through use of research designs known to reduce inefficiencies, and further research should be done to learn how efficiency can be increased. Finally, everyone, particularly those responsible for health-care systems, should promote integration of research into everyday clinical practice. Regulators and researchers should monitor adherence to each of these recommendations and publish metrics.

    Publications by Chinese researchers in scientific journals have dramatically increased over the past decade; however, academic misconduct also becomes more prevalent in the country. The aim of this prospective study was to understand the perceptions of Chinese biomedical researchers towards academic misconduct and the trend from 2010 to 2015. A questionnaire comprising 10 questions was designed and then validated by ten biomedical researchers in China. In the years 2010 and 2015, respectively, the questionnaire was sent as a survey to biomedical researchers at teaching hospitals, universities, and medical institutes in mainland China. Data were analyzed by the Chi squared test, one-way analysis of variance with the Tukey post hoc test, or Spearman's rank correlation method, where appropriate. The overall response rates in 2010 and 2015 were 4.5% (446/9986) and 5.5% (832/15,127), respectively. Data from 15 participants in 2010 were invalid, and analysis was thus performed for 1263 participants. Among the participants, 54.7% thought that academic misconduct was serious-to-extremely serious, and 71.2% believed that the Chinese authorities paid no or little attention to the academic misconduct. Moreover, 70.2 and 65.2% of participants considered that the punishment for academic misconduct at the authority and institution levels, respectively, was not appropriate or severe enough. Inappropriate authorship and plagiarism were the most common forms of academic misconduct. The most important factor underlying academic misconduct was the academic assessment system, as judged by 50.7% of the participants. Participants estimated that 40.1% (39.8 ± 23.5% in 2010; 40.2 ± 24.5% in 2015) of published scientific articles were associated with some form of academic misconduct. Their perceptions towards academic misconduct had not significantly changed over the 5 years. Reform of the academic assessment system should be the fundamental approach to tackling this problem in

    Biomedical research becomes increasingly interdisciplinary and collaborative in nature. Researchers need to efficiently and effectively collaborate and make decisions by meaningfully assembling, mining and analyzing available large-scale volumes of complex multi-faceted data residing in different sources. In line with related research directives revealing that, in spite of the recent advances in data mining and computational analysis, humans can easily detect patterns which computer algorithms may have difficulty in finding, this paper reports on the practical use of an innovative web-based collaboration support platform in a biomedical research context. Arguing that dealing with data-intensive and cognitively complex settings is not a technical problem alone, the proposed platform adopts a hybrid approach that builds on the synergy between machine and human intelligence to facilitate the underlying sense-making and decision making processes. User experience shows that the platform enables more informed and quicker decisions, by displaying the aggregated information according to their needs, while also exploiting the associated human intelligence.

    While ethical concerns about participating in biospecimen research have been previously identified, few studies have reported the concerns among individuals with familial risk for hereditary cancer (IFRs). At the same time, biomedical researchers often lack training in discussing such concerns to potential donors. This study explores IFRs' and biomedical researchers' perceptions of ethical concerns about participating in biobanking research. In separate focus groups, IFRs and biomedical researchers participated in 90-min telephone focus groups. Focus group questions centered on knowledge about laws that protect the confidentiality of biospecimen donors, understanding of informed consent and study procedures, and preferences for being recontacted about potential incidental discovery and also study results. A total of 40 IFRs and 32 biomedical researchers participated in the focus groups. Results demonstrated discrepancies between the perceptions of IFRs and researchers. IFRs' concerns centered on health information protection; potential discrimination by insurers and employers; and preferences for being recontacted upon discovery of gene mutations or to communicate study results. Researchers perceived that participants understood laws protecting donors' privacy and (detailed study information outlined in the informed consent process), study outcomes were used to create a training tool kit to increase researchers' understanding of IFRs' concerns about biobanking.

    Randomized controlled trials and critical social theory are known not to be happy bedfellows. Such trials are embedded in a positivist view of the world, seeking definitive answers to testable questions; critical social theory questions the methods by which we deem the world knowable and may consider experiments in the biomedical sciences as social artifacts. Yet both of these epistemologically and methodologically divergent fields offer potentially important advances in HIV research. In this paper, we describe collaboration between social and biomedical researchers on a large, publicly funded programme to develop vaginal microbicides for HIV prevention. In terms of critical engagement, having integrated and qualitative social science components in the protocol meant potentially nesting alternative epistemologies at the heart of the randomized controlled trial. The social science research highlighted the fallibility and fragility of trial data by demonstrating inconsistencies in key behavioural measurements. It also foregrounded the disjuncture between biomedical conceptions of microbicides and the meanings and uses of the study gel in the context of users' everyday lives. These findings were communicated to the clinical and epidemiological members of the team on an ongoing basis via a feedback loop, through which new issues of concern could also be debated and, in theory, data collection adjusted to the changing needs of the programme. Although critical findings were taken on board by the trialists, a hierarchy of evidence nonetheless remained that limited the utility of some social science findings. This was in spite of mutual respect between clinical epidemiologists and social scientists, equal representation in management and coordination bodies, and equity in funding for the different disciplines. We discuss the positive role that social science integrated into an HIV prevention trial can play, but nonetheless highlight tensions that remain where a hierarchy

    The growing interest of modeling human diseases using genetically modified (transgenic) nonhuman primates (NHPs) is a direct result of NHPs (rhesus macaque, etc.) close relation to humans. NHPs share similar developmental paths with humans in their anatomy, physiology, genetics, and neural functions; and in their cognition, emotion, and social behavior. The NHP model within biomedical research has played an important role in the development of vaccines, assisted reproductive technologies, and new therapies for many diseases. Biomedical research has not been the primary role of NHPs. They have mainly been used for safety evaluation and pharmacokinetics studies, rather than determining therapeutic efficacy. The development of the first transgenic rhesus macaque (2001) revolutionized the role of NHP models in biomedicine. Development of the transgenic NHP model of Huntington's disease (2008), with distinctive clinical features, further suggested the uniqueness of the model system; and the potential role of the NHP model for human genetic disorders. Modeling human genetic diseases using NHPs will continue to thrive because of the latest advances in molecular, genetic, and embryo technologies. NHPs rising role in biomedical research, specifically pre-clinical studies, is foreseeable. The path toward the development of transgenic NHPs and the prospect of transgenic NHPs in their new role in future biomedicine needs to be reviewed. This article will focus on the advancement of transgenic NHPs in the past decade, including transgenic technologies and disease modeling. It will outline new technologies that may have significant impact in future NHP modeling and will conclude with a discussion of the future prospects of the transgenic NHP model. PMID:24174443

    The purpose of this paper is to describe the experiments and methods that led to the geometrical interpretation of new-generation commercial PET-CT scanners, finalized to off-line PET-based treatment verification in ion beam therapy. Typically, the geometrical correspondence between the image domain (i.e., the dicom PET) and the sinogram domain (i.e., the PET raw data) is not explicitly described by scanner vendors. Hence, the proposed characterization can be applied to commercial PET-CT scanners used in biomedical research, for the development of technologies and methods requiring the use of PET raw data, without having access to confidential information from the vendors.

    Industry-sponsored biomedical research is under the microscope. In an attempt to achieve just results in extraordinary cases, critics are suggesting regulations that would pervert the U.S. clinical trial process. However, the arguments made to justify such regulation are weak at best. All the proposals to regulate industry sponsorship of clinical trials that we surveyed (over a hundred articles and ten books, most written in the past decade) suffer from some form of fallacious reasoning. In the interest of advocating sound policy, this article points out some of the most common reasoning errors found in the literature on financial conflicts of interest in clinical trials.

    The increasing need for interdisciplinary team sciences makes it vital for academic research departments to publicize their research and educational resources as part of "linked data" on the semantic web to facilitate research networking and recruitment. We extended an open-source ontology, VIVO, to represent the research and educational resources in an academic biomedical informatics department to enable ontology-based information storage and retrieval. Using participatory design methods, we surveyed representative types of visitors to the department web site to understand their information needs, and incorporated these needs into the ontology design. We added 114 classes and 186 properties to VIVO. Generalizability and scalability are the measures used in our theoretical evaluation.

    Biomedical research networks need to integrate research data among their members and with external partners. To support such data sharing activities, an adequate information technology infrastructure is necessary. To facilitate the establishment of such an infrastructure, we developed a reference model for the requirements. The reference model consists of five reference goals and 15 reference requirements. Using the Unified Modeling Language, the goals and requirements are set into relation to each other. In addition, all goals and requirements are described textually in tables. This reference model can be used by research networks as a basis for a resource efficient acquisition of their project specific requirements. Furthermore, a concrete instance of the reference model is described for a research network on liver cancer. The reference model is transferred into a requirements model of the specific network. Based on this concrete requirements model, a service-oriented information technology architecture is derived and also described in this paper. PMID:25699205

    Clinical and translational research increasingly requires computation. Projects may involve multiple computationally-oriented groups including information technology (IT) professionals, computer scientists and biomedical informaticians. However, many biomedical researchers are not aware of the distinctions among these complementary groups, leading to confusion, delays and sub-optimal results. Although written from the perspective of clinical and translational science award (CTSA) programs within academic medical centers, the paper addresses issues that extend beyond clinical and translational research. The authors describe the complementary but distinct roles of operational IT, research IT, computer science and biomedical informatics using a clinical data warehouse as a running example. In general, IT professionals focus on technology. The authors distinguish between two types of IT groups within academic medical centers: central or administrative IT (supporting the administrative computing needs of large organizations) and research IT (supporting the computing needs of researchers). Computer scientists focus on general issues of computation such as designing faster computers or more efficient algorithms, rather than specific applications. In contrast, informaticians are concerned with data, information and knowledge. Biomedical informaticians draw on a variety of tools, including but not limited to computers, to solve information problems in health care and biomedicine. The paper concludes with recommendations regarding administrative structures that can help to maximize the benefit of computation to biomedical research within academic health centers. PMID:19550198

    Foster, Morris W

    2006-01-01

    Lost in the debate over the use of racial and ethnic categories in biomedical research is community-level analysis of how these categories function and influence health. Such analysis offers a powerful critique of national and transnational categories usually used in biomedical research such as "African-American" and "Native American." Ethnographic research on local African-American and Native American communities in Oklahoma shows the importance of community-level analysis. Local ("intra-community") health practices tend to be shared by members of an everyday interactional community without regard to racial or ethnic identity. Externally created ("extra-community") practices tend to be based on the existence of externally-imposed racial or ethnic identities, but African-American and Native American community members show similar patterns in their use of extra-community practices. Thus, membership in an interactional community seems more important than externally-imposed racial or ethnic identity in determining local health practices, while class may be as or more important in accounting for extra-community practices.

    Human missions beyond low earth orbit to destinations, such as to Mars and asteroids will expose astronauts to novel operational conditions that may pose health risks that are currently not well understood and perhaps unanticipated. In addition, there are limited clinical and research data to inform development and implementation of health risk countermeasures for these missions. Consequently, NASA's Digital Astronaut Project (DAP) is working to develop and implement computational models and simulations (M&S) to help predict and assess spaceflight health and performance risks, and enhance countermeasure development. In order to effectively accomplish these goals, the DAP evaluates its models and simulations via a rigorous verification, validation and credibility assessment process to ensure that the computational tools are sufficiently reliable to both inform research intended to mitigate potential risk as well as guide countermeasure development. In doing so, DAP works closely with end-users, such as space life science researchers, to establish appropriate M&S credibility thresholds. We will present and demonstrate the process the DAP uses to vet computational M&S for space biomedical analysis using real M&S examples. We will also provide recommendations on how the larger space biomedical community can employ these concepts to enhance the credibility of their M&S codes.

    The time it takes for a completed manuscript to be published traditionally can be extremely lengthy. Article publication delay, which occurs in part due to constraints associated with peer review, can prevent the timely dissemination of critical and actionable data associated with new information on rare diseases or developing health concerns such as Zika virus. Preprint servers are open access online repositories housing preprint research articles that enable authors (1) to make their research immediately and freely available and (2) to receive commentary and peer review prior to journal submission. There is a growing movement of preprint advocates aiming to change the current journal publication and peer review system, proposing that preprints catalyze biomedical discovery, support career advancement, and improve scientific communication. While the number of articles submitted to and hosted by preprint servers are gradually increasing, there has been no simple way to identify biomedical research published in a preprint format, as they are not typically indexed and are only discoverable by directly searching the specific preprint server websites. To address this issue, we created a search engine that quickly compiles preprints from disparate host repositories and provides a one-stop search solution. Additionally, we developed a web application that bolsters the discovery of preprints by enabling each and every word or phrase appearing on any web site to be integrated with articles from preprint servers. This tool, search.bioPreprint, is publicly available at http://www.hsls.pitt.edu/resources/preprint. PMID:27508060

    Big data technologies are increasingly used for biomedical and health-care informatics research. Large amounts of biological and clinical data have been generated and collected at an unprecedented speed and scale. For example, the new generation of sequencing technologies enables the processing of billions of DNA sequence data per day, and the application of electronic health records (EHRs) is documenting large amounts of patient data. The cost of acquiring and analyzing biomedical data is expected to decrease dramatically with the help of technology upgrades, such as the emergence of new sequencing machines, the development of novel hardware and software for parallel computing, and the extensive expansion of EHRs. Big data applications present new opportunities to discover new knowledge and create novel methods to improve the quality of health care. The application of big data in health care is a fast-growing field, with many new discoveries and methodologies published in the last five years. In this paper, we review and discuss big data application in four major biomedical subdisciplines: (1) bioinformatics, (2) clinical informatics, (3) imaging informatics, and (4) public health informatics. Specifically, in bioinformatics, high-throughput experiments facilitate the research of new genome-wide association studies of diseases, and with clinical informatics, the clinical field benefits from the vast amount of collected patient data for making intelligent decisions. Imaging informatics is now more rapidly integrated with cloud platforms to share medical image data and workflows, and public health informatics leverages big data techniques for predicting and monitoring infectious disease outbreaks, such as Ebola. In this paper, we review the recent progress and breakthroughs of big data applications in these health-care domains and summarize the challenges, gaps, and opportunities to improve and advance big data applications in health care.

    2013-03-01

    Today, European biomedical and health-related research is insufficiently well funded and is fragmented, with no common vision, less-than-optimal sharing of resources, and inadequate support and training in clinical research. Improvements to the competitiveness of European biomedical research will depend on the creation of new infrastructures that must be dynamic and free of bureaucracy, involve all stakeholders and facilitate faster delivery of new discoveries from bench to bedside. Taking diabetes research as the model, a new paradigm for European biomedical research is presented, which offers improved co-ordination and common resources that will benefit both academic and industrial clinical research. This includes the creation of a European Council for Health Research, first proposed by the Alliance for Biomedical Research in Europe, which will bring together and consult with all health stakeholders to develop strategic and multidisciplinary research programmes addressing the full innovation cycle. A European Platform for Clinical Research in Diabetes is proposed by the Alliance for European Diabetes Research (EURADIA) in response to the special challenges and opportunities presented by research across the European region, with the need for common standards and shared expertise and data.

    The evolution of biomedical research grant collaborations (BRGC) across time (2006, 2009) and hierarchically related scales (Staff, Department) at the University of Arkansas for Medical Sciences (UAMS) is investigated using network abstractions. This baseline study is a part of the Clinical Translational Science Award (CTSA) efforts in promoting team science and exploring network science approaches for CTSA evaluation. The BRGC data were retrieved from the internally developed grants management system (Automated Research Information Administrator, ARIA). Our analysis revealed the BRGC networks to be disconnected with mutually exclusive research clusters. However, a dominant weakly-connected cluster with positively skewed degree centrality and betweenness distribution was observed across scales and time. Variation in the centrality measures, clustering coefficient, and the impact of perturbing the most-influential nodes as a function of time and scale is investigated. The results presented provide novel insights into the complex nature of BRGC networks that may persist across similar settings.

    This study deals with issues of research with human embryos obtained through in vitro fertilization in the context of the Spanish Law. The paper focuses on Act 14/2006 on techniques of human assisted reproduction, which replaces the previous Act from 1988. The author claims that the main goals of Act 14/2006 are, on the one hand, to eliminate the restrictions affecting research with human embryos put in place by Act 45/2003 and, on the other, to pave the way for a future legislation on biomedical research. This paper argues for the need of an effective and adequate juridical protection of human embryos obtained in vitro according to responsibility and precautionary principles.

    The Department of Energy (DOE) has prepared an Environmental Assessment (EA) evaluating the proposed construction and operation of the Strom Thurmond Biomedical Research Center (Center) at the Medical University of South Carolina (MUSC), Charleston, SC. The DOE is evaluating a grant proposal to authorize the MUSC to construct, equip and operate the lower two floors of the proposed nine-story Center as an expansion of on-going clinical research and out-patient diagnostic activities of the Cardiology Division of the existing Gazes Cardiac Research Institute. Based on the analysis in the EA, the DOE has determined that the proposed action does not constitute a major federal action significantly affecting the quality of the human environment within the meaning of the NEPA. Therefore, the preparation of an Environmental Impact Statement is not required.

    2016-06-01

    A major branch of glycobiology and glycan-focused biomedicine studies the interaction between carbohydrates and other biopolymers, most importantly, glycan-binding proteins. Today, this research into glycan-biopolymer interaction is unthinkable without glycan arrays, tools that enable high-throughput analysis of carbohydrate interaction partners. Glycan arrays offer many applications in basic biochemical research, for example, defining the specificity of glycosyltransferases and lectins such as immune receptors. Biomedical applications include the characterization and surveillance of influenza strains, identification of biomarkers for cancer and infection, and profiling of immune responses to vaccines. Here, we review major applications of glycan arrays both in basic and applied research. Given the dynamic nature of this rapidly developing field, we focus on recent findings.

  20. Candidate bird species for use in aging research.

    PubMed

    Austad, Steven N

    2011-01-01

    Birds live about 3 times as long as an average mammal of similar size. They exhibit this remarkable resistance to the degenerative processes of aging despite traits such as elevated body temperature, a rapid metabolic rate, and high blood glucose that might lead one to expect them to be especially short-lived. Although birds appear to age slowly, the patterns of age-related deterioration and development of disease parallel in many ways those of mammals such as humans. Therefore, birds may reveal novel mechanisms of resistance to senescence. A previous impediment to the use of birds in modern biomedical research was the inability to perform targeted genetic manipulations, which has revolutionized the use of other model species. But with the publication of the whole genome sequence of two bird species and the development of gene knockdown technology and tissue-specific transgenesis, this impediment seems to be disappearing. At least five bird species deserve special attention for development as models of successful aging. Three of these species--budgerigars, canaries, and zebra finches--are common cage birds and are already used extensively in the study of vocal learning and sustained neurogenesis in adulthood. In addition, two wild species--the European starling and the house sparrow--may also make excellent models for aging research.

    Background: Robust statistical designing, sound statistical analysis, and standardized presentation are important to enhance the quality and transparency of biomedical research. This systematic review was conducted to summarize the statistical reporting requirements introduced by biomedical research journals with an impact factor of 10 or above so that researchers are able to give statistical issues’ serious considerations not only at the stage of data analysis but also at the stage of methodological design. Methods: Detailed statistical instructions for authors were downloaded from the homepage of each of the included journals or obtained from the editors directly via email. Then, we described the types and numbers of statistical guidelines introduced by different press groups. Items of statistical reporting guideline as well as particular requirements were summarized in frequency, which were grouped into design, method of analysis, and presentation, respectively. Finally, updated statistical guidelines and particular requirements for improvement were summed up. Results: Totally, 21 of 23 press groups introduced at least one statistical guideline. More than half of press groups can update their statistical instruction for authors gradually relative to issues of new statistical reporting guidelines. In addition, 16 press groups, covering 44 journals, address particular statistical requirements. The most of the particular requirements focused on the performance of statistical analysis and transparency in statistical reporting, including “address issues relevant to research design, including participant flow diagram, eligibility criteria, and sample size estimation,” and “statistical methods and the reasons.” Conclusions: Statistical requirements for authors are becoming increasingly perfected. Statistical requirements for authors remind researchers that they should make sufficient consideration not only in regards to statistical methods during the research

    As the costs associated with treatment of mixed wastes by conventional methods increase, new technologies will be investigated as alternatives. This study examines the potential of using a selected mixed population of microorganisms to treat hazardous chemical compounds in liquid low level radioactive wastes from biomedical research procedures. Microorganisms were isolated from various waste samples and enriched against compounds known to occur in the wastes. Individual isolates were tested for their ability to degrade methanol, ethanol, phenol, toluene, phthalates, acetonitrile, chloroform, and trichloroacetic acid. Following these tests, the organisms were combined in a media with a mixture of the different compounds. Three compounds: methanol, acetonitrile, and pseudocumene, were combined at 500 microliter/liter each. Degradation of each compound was shown to occur (75% or greater) under batch conditions with the mixed population. Actual wastes were tested by adding an aliquot to the media, determining the biomass increase, and monitoring the disappearance of the compounds. The compounds in actual waste were degraded, but at different rates than the batch cultures that did not have waste added. The potential of using bioprocessing methods for treating mixed wastes from biomedical research is discussed.

    2016-01-01

    There has been prolonged and significant interest in manipulating the genome for a wide range of applications in biomedical research and medicine. An existing challenge in realizing this potential has been the inability to precisely edit specific DNA sequences. Past efforts to generate targeted double stranded DNA cleavage have fused DNA-targeting elements such as zinc fingers and DNA-binding proteins to endonucleases. However, these approaches are limited by both design complexity and inefficient, costineffective operation. The discovery of CRISPR/Cas9, a branch of the bacterial adaptive immune system, as a potential genomic editing tool holds the promise of facile targeted cleavage. Its novelty lies in its RNA-guided endonuclease activity, which enhances its efficiency, scalability, and ease of use. The only necessary components are a Cas9 endonuclease protein and an RNA molecule tailored to the gene of interest. This lowbarrier of adoption has facilitated a plethora of advances in just the past three years since its discovery. In this review, we will discuss the impact of CRISPR/Cas9 on biomedical research and its potential implications in medicine.

    We developed the Biomedical Informatics Researchers ranking website (rank.informatics-review.com) to overcome many of the limitations of previous scientific productivity ranking strategies. The website is composed of four key components that work together to create an automatically updating ranking website: (1) list of biomedical informatics researchers, (2) Google Scholar scraper, (3) display page, and (4) updater. The site has been useful to other groups in evaluating researchers, such as tenure and promotions committees in interpreting the various citation statistics reported by candidates. Creation of the Biomedical Informatics Researchers ranking website highlights the vast differences in scholarly productivity among members of the biomedical informatics research community.

    Researchers, stakeholders and policy makers agree about the importance of the population ageing in modern societies, so a broad analysis of current research strategies is in progress, such as FUTURAGE, a network for drawing a map for future research on ageing. This document presents the Spanish contribution to this map following FUTURAGE guidelines, drawn from the debates held in the 'Ageing. Research in Spain and Europe' Workshop. The first part consists of general ideas seeking to define future challenges on research using a multidisciplinary approach, in which the theoretical and methodological debate, the comparative and multilevel perspective, the transfer of knowledge and involvement of the older people would be essential to consider. Some of the main issues according to FUTURAGE structure are, the bio-gerontology of ageing, healthy and active ageing, and the socioeconomic and environmental resources of ageing. The interaction between these contents is pivotal to understand the research on ageing. Finally, the document provides some methodological and instrumental ideas to reinforce the need for cross-sectional research initiatives, integrating different data and combining methods in order to develop assessment and intervention strategies. Other aspects look into the mechanisms to coordinate research within a European context. The map on ageing research has been published after the consultation process in Europe (http://futurage.group.shef.ac.uk/road-map.html) and is now ready to be considered for integration into future European and Spanish research programs.

  7. United Nations and human cloning: a slender and fortunate defence for biomedical research.

    2003-12-01

    Numerous biomedical scientists have contributed to the wide knowledge on the growth of preimplantation human embryos in vitro, now improving every aspect of the form of clinical care. These data were gained ethically in many countries, to open new vistas including the alleviation of infertility, preimplantation genetic diagnosis and stem cells, combined with some recent reports on human reproductive cloning. After detailed consultations with scientists, clinicians, ethicists and lawyers, many governments passed legislation permitting research under their own particular socially-defined conditions. Virtually all of them rejected reproductive cloning; a few have accepted therapeutic cloning. These legislatures saluted the many biomedical scientists striving to improve IVF and its derivatives, recognizing their immense medical potential. A motion recently placed before the United Nations then recommended a worldwide ban on all forms of human cloning. Proponents included the Vatican and many Roman Catholic countries, the USA and others. Opponents included Belgium, China, Japan, Brazil, UK, Germany and France. Mediation was achieved by Iran and other Muslim nations, and led to a motion passed by single vote for a two-year delay. This may be the first-ever proposal to ban worldwide a particular form of research. It sounds the alarm bells for further research. It raises questions about the UN being an appropriate forum for ethical decisions affecting the entire world and its future medicine. Large blocs of nations committed to particular religions and outlooks confronted each other, a situation in total contrast to the detailed and widespread consultations made by individual governments when deciding their own individual ethics. This event was clearly a narrow escape for free research as defined by each country's own jurisprudence. It also places research on human embryology and reproductive biomedicine into a more critical situation than before. Current liberalism in

    outstanding scientists dedicated to using domestic animal models for agricultural and biomedical research, strong incentives for scientists to take advantage of training opportunities to write NIH grants, and greater NIH and USDA cooperation to sponsor the use of agricultural animals as dual-purpose animal models that benefit agriculture and biomedicine will also be necessary. In conclusion, the broad diversity of animal models needed for agricultural and biomedical research is at risk unless research priorities at the land grant universities are critically evaluated and financial support for such research is dramatically increased.

    The clinical information stored in registries and records of different types is a fundamental tool for biomedical research. Up until just a few years ago, hardly any limitations existed on the creation and use of epidemiological registries or the use of information from pre-existing records for research purposes. This situation has changed substantially due mainly to the growing importance current laws place upon the safeguarding of the privacy and confidentiality of personal data. Although the legal framework is already quite explicit, a certain degree of leeway exists for ethical debate and prudence advice for the purpose of conducting valid, useful research with this information which will also respect the rights of the subjects and the laws in force. These guidelines deal with those aspects which have been considered relevant from an ethical standpoint in the handling of records and registries for research-related purposes, including not only the use but also the creation proper of the registries. A total of twenty-four recommendations are provided, grouped into ten sections: warranting of the creation of registry, organization and definition of responsibilities, scientific validity of the research project, ethical requirements of the collections of anonymous and anonymized data, ethical requirements of the registries including personal data, uses of medical records for research purposes, use of historical records of deceased individuals, contact with the research subjects, notification of results and review by a Research Ethics Committee.

    2013-01-01

    There are two primary human subject protections: assessing and comparing the risks and potential benefits of proposed research, and obtaining potential subjects’ informed consent. While there has been extensive discussion in the literature on these two aspects, no attention has been paid to whether the processes should be different when the objective of an experimental biomedical intervention is to improve individual performance or capacity (“enhancement research”) rather than to prevent, cure, or mitigate disease (“health-oriented research”). This essay examines how both assessment of risks and benefits, and obtaining informed consent in an enhancement experiment might differ from the approaches used in health-oriented investigations, and considers appropriate protections for subjects in enhancement research.

    Research data and biospecimen repositories are valuable resources for biomedical investigators. Sharing these resources has great potential benefits including efficient use of resources, avoiding duplicate experiments, gathering adequate sample sizes, and promoting collaboration. However, concerns from data producers about difficulties of getting proper acknowledgement for their data contributions are increasingly becoming obstacles for efficient and large-scale data sharing in reality. In this research project we analyzed the inadequacy of current policy-based solution for promoting data sharing. The recommendations in this paper emphasize data publication and citation. This project aims to promote the acknowledgement of data contributors with realizable informatics tools that augment informal policy-level strategies, and do so in a way that promotes data sharing.

    The discipline of biomedical and health informatics has seen substantial change in practice as well as education in recent years. Most early programs in the field focused on either post-doctoral apprenticeship-like experiences or PhD degrees, usually with a strong research emphasis. More recently, however, a variety of new educational options have emerged, from certificate and professional master's programs to shorter courses, such as the AMIA 10x10 program. Other programs have emerged from the health information management field as well as at the undergraduate level. At the same time, the real growth and need for informatics expertise has emerged more in operational than academic settings. In this talk, an informatics educational leader and innovator will describe these changes, the research data that has explored them, and how they have impacted informatics educational programs, including his own at Oregon Health & Science University.

    Lawrence Livermore`s Center for Accelerator Mass Spectrometry (AMS) is one of the leading AMS facilities in the world, performing about 25% of all AMS analyses. It is also at the forefront of the emerging field of AMS as applied to biomedical research. AMS is so sensitive that it can identify just a few molecules of a substance among trillions of molecules. This sensitivity makes possible for the first time the study of toxins, dietary nutrients, drugs, and other substances in dosages that are relevant to humans. Work with volunteer subjects indicates that a chemical that is produced when meat is cooked adversely affects human DNA more than it does the DNA of laboratory animals. This research supports the need to pursue additional human biological risk assessment using AMS. Livermore is also performing studies of the human metabolism of calcium, which are difficult without AMS.

    This paper describes a distributed collaborative effort between industry and academia to systematize data management in an academic biomedical laboratory. Heterogeneous and voluminous nature of research data created in biomedical laboratories make information management difficult and research unproductive. One such collaborative effort was evaluated over a period of four years using data collection methods including ethnographic observations, semi-structured interviews, web-based surveys, progress reports, conference call summaries, and face-to-face group discussions. Data were analyzed using qualitative methods of data analysis to (1) characterize specific problems faced by biomedical researchers with traditional information management practices, (2) identify intervention areas to introduce a new research information management system called Labmatrix, and finally to (3) evaluate and delineate important general collaboration (intervention) characteristics that can optimize outcomes of an implementation process in biomedical laboratories. Results emphasize the importance of end user perseverance, human-centric interoperability evaluation, and demonstration of return on investment of effort and time of laboratory members and industry personnel for success of implementation process. In addition, there is an intrinsic learning component associated with the implementation process of an information management system. Technology transfer experience in a complex environment such as the biomedical laboratory can be eased with use of information systems that support human and cognitive interoperability. Such informatics features can also contribute to successful collaboration and hopefully to scientific productivity.

    This paper describes a distributed collaborative effort between industry and academia to systematize data management in an academic biomedical laboratory. Heterogeneous and voluminous nature of research data created in biomedical laboratories make information management difficult and research unproductive. One such collaborative effort was evaluated over a period of four years using data collection methods including ethnographic observations, semi-structured interviews, web-based surveys, progress reports, conference call summaries, and face-to-face group discussions. Data were analyzed using qualitative methods of data analysis to 1) characterize specific problems faced by biomedical researchers with traditional information management practices, 2) identify intervention areas to introduce a new research information management system called Labmatrix, and finally to 3) evaluate and delineate important general collaboration (intervention) characteristics that can optimize outcomes of an implementation process in biomedical laboratories. Results emphasize the importance of end user perseverance, human-centric interoperability evaluation, and demonstration of return on investment of effort and time of laboratory members and industry personnel for success of implementation process. In addition, there is an intrinsic learning component associated with the implementation process of an information management system. Technology transfer experience in a complex environment such as the biomedical laboratory can be eased with use of information systems that support human and cognitive interoperability. Such informatics features can also contribute to successful collaboration and hopefully to scientific productivity. PMID:26652980

    The Aotus nancymaae species has been of great importance in researching the biology and pathogenesis of malaria, particularly for studying Plasmodium molecules for including them in effective vaccines against such microorganism. In spite of the forgoing, there has been no report to date describing the biology of parasite target cells in primates or their biomedical importance. This study was thus designed to analyse A. nancymaae erythrocyte protein composition using MS data collected during a previous study aimed at characterising the Plasmodium vivax proteome and published in the pertinent literature. Most peptides identified were similar to those belonging to 1189 Homo sapiens molecules; >95% of them had orthologues in New World primates. GO terms revealed a correlation between categories having the greatest amount of proteins and vital cell function. Integral membrane molecules were also identified which could be possible receptors facilitating interaction with Plasmodium species. The A. nancymaae erythrocyte proteome is described here for the first time, as a starting point for more in-depth/extensive studies. The data reported represents a source of invaluable information for laboratories interested in carrying out basic and applied biomedical investigation studies which involve using this primate.

  3. Research in intelligent biomedical clothing vs. realities in the European textile business.

    In order to make intelligent biomedical clothing a market reality, a critical mass of scientific, technical and industrial capacities from various disciplines and industries must be successfully brought together. The textiles and clothing sector, i.e. the industry that transform natural or man-made fibres into yarns then with a myriad of processing options into complex tissues and finally into clothing, is undoubtedly a crucial element in such development. With Europe disposing of the world's most diverse, productive and innovative textiles and clothing industry, in addition to relevant expertise and resources in other scientific disciplines and industrial sectors, it could play a leading role in the advancement of the concept of intelligent biomedical clothing. In this process, a great number of challenges--firstly scientific and technical in nature--still need to be overcome and support from public funding programmes could constitute the necessary trigger for research and industrial efforts to be seriously undertaken. In view of the great benefits of such new products for the individual consumer, national health care systems and the society as a whole, a concerted effort in private-public partnership seems merited.

    Measuring and predicting the success of junior faculty is of considerable interest to faculty, academic institutions, funding agencies and faculty development and mentoring programs. Various metrics have been proposed to evaluate and predict research success and impact, such as the h-index, and modifications of this index, but they have not been evaluated and validated side-by-side in a rigorous empirical study. Our study provides a retrospective analysis of how well bibliographic metrics and formulas (numbers of total, first- and co-authored papers in the PubMed database, numbers of papers in high-impact journals) would have predicted the success of biomedical investigators (n = 40) affiliated with the University of Nevada, Reno, prior to, and after completion of significant mentoring and research support (through funded Centers of Biomedical Research Excellence, COBREs), or lack thereof (unfunded COBREs), in 2000-2014. The h-index and similar indices had little prognostic value. Publishing as mid- or even first author in only one high-impact journal was poorly correlated with future success. Remarkably, junior investigators with >6 first-author papers within 10 years were significantly (p < 0.0001) more likely (93%) to succeed than those with ≤6 first-author papers (4%), regardless of the journal's impact factor. The benefit of COBRE-support increased the success rate of junior faculty approximately 3-fold, from 15% to 47%. Our work defines a previously neglected set of metrics that predicted the success of junior faculty with high fidelity-thus defining the pool of faculty that will benefit the most from faculty development programs such as COBREs.

    The Digital Astronaut is an integrated, modular modeling and database system that will support space biomedical research and operations in a variety of fundamental ways. This system will enable the identification and meaningful interpretation of the medical and physiological research required for human space exploration, a determination of the effectiveness of specific individual human countermeasures in reducing risk and meeting health and performance goals on challenging exploration missions and an evaluation of the appropriateness of various medical interventions during mission emergencies, accidents and illnesses. Such a computer-based, decision support system will enable the construction, validation and utilization of important predictive simulations of the responses of the whole human body to the types of stresses experienced during space flight and low-gravity environments. These simulations will be essential for direct, real-time analysis and maintenance of astronaut health and performance capabilities. The Digital Astronaut will collect and integrate past and current human data across many physiological disciplines and simulations into an operationally useful form that will not only summarize knowledge in a convenient and novel way but also reveal gaps that must be filled via new research in order to effectively ameliorate biomedical risks. Initial phases of system development will focus on simulating ground-based analog systems that are just beginning to collect multidisciplinary data in a standardized way (e.g., the International Multidisciplinary Artificial Gravity Project). During later phases, the focus will shift to development and planning for missions and to exploration mission operations. Then, the Digital Astronaut system will enable evaluation of the effectiveness of multiple, simultaneously applied countermeasures (a task made difficult by the many-system physiological effects of individual countermeasures) and allow for the prescription of

    The purpose of this article is to describe research and teaching activities related to healthy ageing, narrative methods and research ethics at the Nordic School of Public Health NHV during 1999 - 2012. Healthy ageing was conceived in terms of The World Health Organization's (WHO) model of active ageing and of quality of life defined as a sense of well-being, meaning and value. Qualitative research on ageing and health conducted at NHV showed how elderly people themselves experience health and what they perceive to be health promoting. Narrative method was one the qualitative methods used in research at NHV. By adopting holistic and categorical content analysis the life stories of elderly Finnish migrants, the stories of home-dwelling persons about falls, and working persons' stories of alcohol use were studied. The courses on research ethics took their point of departure in a model that describes the role of scientific, economic, aesthetic and ethical values in research.

    The Second International Conference and Young Scientist School ''Magnetic resonance imaging in biomedical research'' was held on the campus of the National Research Tomsk State University (Tomsk, Russia) on September 7-9, 2015. The conference was focused on magnetic resonance imaging (MRI) applications for biomedical research. The main goal was to bring together basic scientists, clinical researchers and developers of new MRI techniques to bridge the gap between clinical/research needs and advanced technological solutions. The conference fostered research and development in basic and clinical MR science and its application to health care. It also had an educational purpose to promote understanding of cutting-edge MR developments. The conference provided an opportunity for researchers and clinicians to present their recent theoretical developments, practical applications, and to discuss unsolved problems. The program of the conference was divided into three main topics. First day of the conference was devoted to educational lectures on the fundamentals of MRI physics and image acquisition/reconstruction techniques, including recent developments in quantitative MRI. The second day was focused on developments and applications of new contrast agents. Multinuclear and spectroscopic acquisitions as well as functional MRI were presented during the third day of the conference. We would like to highlight the main developments presented at the conference and introduce the prominent speakers. The keynote speaker of the conference Dr. Vasily Yarnykh (University of Washington, Seattle, USA) presented a recently developed MRI method, macromolecular proton fraction (MPF) mapping, as a unique tool for modifying image contrast and a unique tool for quantification of the myelin content in neural tissues. Professor Yury Pirogov (Lomonosov Moscow State University) described development of new fluorocarbon compounds and applications for biomedicine. Drs. Julia Velikina and Alexey

    We examine effects of government spending on postdoctoral researchers’ (postdocs) productivity in biomedical sciences, the largest population of postdocs in the US. We analyze changes in the productivity of postdocs before and after the US government’s 1997 decision to increase NIH funding. In the first round of analysis, we find that more government spending has resulted in longer postdoc careers. We see no significant changes in researchers’ productivity in terms of publication and conference presentations. However, when the population is segmented by citizenship, we find that the effects are heterogeneous; US citizens stay longer in postdoc positions with no change in publications and, in contrast, international permanent residents (green card holders) produce more conference papers and publications without significant changes in postdoc duration. Possible explanations and policy implications of the analysis are discussed. PMID:25932942

    The Annual Biomedical Research Conference for Minority Students (ABRCMS) is designed to support undergraduate students’ professional development as future scientists. Juniors, seniors, and postbaccalaureates who attended ABRCMS during 2008–2011 were emailed a link to an online questionnaire in which they reported their experiences at the conference. Attendees reported many ABRCMS-provided benefits. Frequency of attending or presenting at ABRCMS is positively related to science self-efficacy, research confidence, sense of belonging in science, and intentions to pursue a research degree in graduate school. Increased research confidence predicts graduate school plans and intentions for a research career in science; however, men were slightly more likely to intend to pursue a research career than women, likely due to higher research confidence. Although all attendees benefited from ABRCMS, underrepresented minority (URM) students had higher science self-efficacy and sense of belonging in science after attending ABRCMS than non-URM students. This finding demonstrates the effectiveness of ABRCMS as an intervention to increase the representation and success of URMs in science. Results highlight the importance of attending a minority-oriented research conference where URMs can develop their science self-efficacy, research confidence, and sense of belonging in science. However, changes to the conference and undergraduate research experiences may be necessary to reduce gender gaps. PMID:27562962

    Universities are increasingly regarded as key actors in the new 'knowledge economy', with requirements to produce market-oriented knowledge and engage in commercialization. This is of particular significance in the biomedical field, reflecting the perceived gap between success in terms of scientific discoveries and its transformation into products. The dominant discourse attributes this situation to 'blocks' in the translational pathway from 'bench to bedside', leading to policies to 'reengineer' the research enterprise. This study examines a pilot initiative established by the UK's Medical Research Council (MRC). This involved employing a change agent (Research Translator) supported by a small amount of translational funding to promote the culture and practice of translational research at a university/hospital site in England. An ethnographically informed case study involving semi-structured and open exploratory interviews, observation and document review, was conducted in 2008. Analysis and interpretation were informed by Bourdieu's logic of practice applied to science. The requirements of translational research promoted by the Research Translator and its sources of capital (authority, prestige etc) were largely congruent with the 'field' of clinical science. In contrast, translational research diverged from perceptions of 'legitimate' science and requirements for capital accumulation held by the majority of basic scientists who often described this research as 'high risk' and were resistant to the Research Translator's advice. However some differences in motivations and practices were identified within groups of scientists associated with career stage, work environment and specialty. We argue that there are convergent and divergent forces that influence scientists' readiness to adopt a market-oriented translational research model and in turn facilitate or constrain the effectiveness of a knowledge broker. We also identify ways in which current structures and

    Summary Objective What are the determining factors for good research in medical informatics or, from a broader perspective, in biomedical and health informatics? Method From the many lessons learned during my professional career, I tried to identify a fair sampling of such factors. On the occasion of giving the IMIA Award of Excellence lecture during MedInfo 2013, they were presented for discussion. Results Sixteen determining factors (df) have been identified: early identification and promotion (df1), appropriate education (df2), stimulating persons and environments (df3), sufficient time and backtracking opportunities (df4), breadth of medical informatics competencies (df5), considering the necessary preconditions for good medical informatics research (df6), easy access to high-quality knowledge (df7), sufficient scientific career opportunities (df8), appropriate conditions for sustainable research (df9), ability to communicate and to solve problems (df10), as well as to convey research results (df11) in a highly inter- and multidisciplinary environment, ability to think for all and, when needed, taking the lead (df12), always staying unbiased (df13), always keeping doubt (df14), but also always trying to provide solutions (df15), and, finally, being aware that life is more (df16). Conclusions Medical Informatics is an inter- and multidisciplinary discipline “avant la lettre”. Compared to monodisciplinary research, inter- and multidisciplinary research does not only provide significant opportunities for solving major problems in science and in society. It also faces considerable additional challenges for medical informatics as a scientific field. The determining factors, presented here, are in my opinion crucial for conducting successful research and for developing a research career. Since medical informatics as a field has today become an important driving force for research progress, especially in biomedicine and health care, but also in fields like

    Objective To investigate the nature of physicians' use of research evidence in experimental conditions of open access to inform training and policy. Design This qualitative study was a component of a larger mixed-methods initiative that provided 336 physicians with relatively complete access to research literature via PubMed and UpToDate, for 1 year via an online portal, with their usage recorded in web logs. Using a semistructured interview protocol, a subset of 38 physician participants were interviewed about their use of research articles in general and were probed about their reasons for accessing specific articles as identified through their web logs. Transcripts were analysed using a general inductive approach. Setting Physician participants were recruited from and registered in the USA. Participants 38 physicians from 16 US states, engaged in 22 medical specialties, possessing more than 1 year of experience postresidency training participated. Results 26 participants attested to the value of consulting research literature within the context of the study by making reference to their roles as clinicians, educators, researchers, learners, administrators and advocates. The physicians reported previously encountering what they experienced as a prohibitive paywall barrier to the research literature and other frustrations with the nature of information systems, such as the need for passwords. Conclusions The findings, against the backdrop of growing open access to biomedical research, indicate that a minority of physicians, at least initially, is likely to seek out and use research and do so in a variety of common roles. Physicians' use of research in these roles has not traditionally been part of their training or part of the considerations for open access policies. The findings have implications for educational and policy initiatives directed towards increasing the effectiveness of this access to and use of research in improving the quality of healthcare

    During the last decade, there has been a significant increase in the use of computers in biomedical research. In particular, the use of these instruments in experimental control, as well as in the acquisition and storage of experimental data, has become universal. The current capacity of these machines enables the precise manipulation of many experimental variables and allows for very fast acquisition of data. In this article, we discuss the fundamentals of small personal computers and its use in experimental control and data acquisition. Further, we discuss technical aspects related to the management of measurement instrument's control and their technical limitations. Electrical recordings from the cerebral cortex are used as examples to illustrate the different aspect included in this article.

    2014-01-01

    Biomedical research projects show an increasing demand of large numbers of participants from different recruiting centers to achieve statistically significant results. The collected types of data are stored in distributed databases and are linked to the participant by different non-resolvable identifiers (layered pseudonyms) for de-identification. To ensure the quality of the gathered data, regular quality assurance analyses are required at each local center. Because of the distributed databases and layered pseudonyms the analyses can only be achieved manually. Therefore, the process is error-prone and laborious. The objective of this paper is to propose a solution concept to automate the manual process by using a local study participant management system. It orchestrates the process and enables the quality assurance analyses within a clinical data warehouse.

    Over the next few years, it will become apparent just how important lunar exploration is to biomedical research and vice versa, and how critical both are to the future of human spaceflight. NASA's Project Constellation should put a new lunar-capable vehicle into service by 2014 that will rely on proven Space Shuttle components and allow four astronauts to spend 7 d on the lunar surface. A modern space transportation system opens up a unique opportunity in the space sciences--the establishment of a permanent lunar laboratory for the physical and life sciences. This commentary presents a rationale for focusing American efforts in space on such a Moon base in order to promote understanding of the long-term physiological effects of living on a planetary body outside the Van Allen belts.

    Despite recent evidence that suggests that knowledge production within the medical community is increasingly based on knowledge-making coalitions or what some have called the co-production of knowledge, there remains a strong expert led policy agenda in many countries in relation to human genome research. This article reports on the role of experts in defining the scope of discussion in relation to the biomedical use of human tissue sample collections or biobanks in Finland using the case of the Genome Information Center. It is argued that the rhetorical strategies should not be understood simply as subversive tactics, but rather as ways of engaging the public within particular contexts of creating commercial expectations and visions which are easier to negotiate from a policy perspective.

    Here I show that a “pure” research project, seemingly totally lacking in practical application when it was first published, can years later spark a whole new scientific field with the potential to revolutionize clinical practice. A 1961 publication describing adducts of nitric oxide (NO) with certain nucleophiles attracted little notice at the time, but later work showing that the adducts could be hydrolyzed to regenerate the NO in bioactive form has provided the foundation for a host of biomedical applications. Crucial to the discovery of widely used tools for studying NO’s chemical biology as well as for the design of a variety of promising therapeutic advances has been the increasingly detailed understanding of the physicochemical properties of these “diazeniumdiolates” (also known as NONOates).

    Planar microelectrode arrays (MEAs) are devices that can be used in biomedical and basic in vitro research to provide extracellular electrophysiological information about biological systems at high spatial and temporal resolution. Complementary metal oxide semiconductor (CMOS) is a technology with which MEAs can be produced on a microscale featuring high spatial resolution and excellent signal-to-noise characteristics. CMOS MEAs are specialized for the analysis of complete electrogenic cellular networks at the cellular or subcellular level in dissociated cultures, organotypic cultures, and acute tissue slices; they can also function as biosensors to detect biochemical events. Models of disease or the response of cellular networks to pharmacological compounds can be studied in vitro, allowing one to investigate pathologies, such as cardiac arrhythmias, memory impairment due to Alzheimer's disease, or vision impairment caused by ganglion cell degeneration in the retina.

    Success of the Clinical Translational Science Award (CTSA) program implicitly demands team science efforts and well-orchestrated collaboration across the translational silos (T1-T4). Networks have proven to be useful abstractions of research collaborations. Networks provide novel system-level insights and exhibit marked changes in response to external interventions, making them potential evaluation tools that complement more traditional approaches. This study is part of our ongoing efforts to assess the impact of the CTSA on Biomedical Research Grant Collaboration (BRGC). Collaborative research grants are a complex undertaking and an outcome of sustained interaction among researchers. In this report, BRGC networks representing collaborations among CTSA-affiliated investigators constructed from grants management system data at the University of Kentucky across a period of six years (2007-2012) corresponding to pre- and post-CTSA are investigated. Overlapping community structure detection algorithms, in conjunction with surrogate testing, revealed the presence of intricate research communities rejecting random graphs as generative mechanisms. The deviation from randomness was especially pronounced post-CTSA, reflecting an increasing trend in collaborations and team-science efforts potentially as a result of CTSA. Intercommunity cross talk was especially pronounced post-CTSA.

    Perceptions of biomedical engineering are important because they can influence private and public decisions on R&D funding and public policy. A survey was conducted of a group of persons active in biomedical engineering research in an attempt to determine the perceptions of the general public and of the biomedical community regarding biomedical engineering. The public is believed to have 'a little' knowledge of biomedical engineering, and to have a wide range of opinions on what biomedical engineers do. The survey respondents believe they are in general agreement with the public on several questions regarding biomedical engineering. However, the public is believed to be more inclined than workers in the field to think that biomedical engineering increases the cost of health care, and to be less supportive of increased R&D funding for health care technology.

    Who owns the human body? This issue has been formerly raised about the status of the slave. Today, it has become a prominent stake for when reflecting on biomedical research and healthcare practices. In our cultures, many answers may be given to this question : they are derived from philosophical or theological traditions ; they are borrowed from anthropological, sociological or psychological knowledge ; they may be formulated in a moral or political perspective. All of them give different insights and reveal one of the various dimensions of the question. When examining the status of the body and its relation to the human subject in the various stages of his/her life (including his/her death), one of the main difficulties is to deal with each of these answers and to understand how they meet and interact in the public debate. Another matter is related to the fact that law also plays a crucial role in the process of giving an answer to this question. In our book, A qui appartient le corps humain ? Médecine, politique et droit (Paris, Belles Lettres, 2004), Claire Crignon-De Oliveira and I have tried to deal with both difficulties. In this article, I focus on the meaning of the various law traditions. In western world, the laws are all derived, up to a certain extent, from the Roman tradition. Whether they have chosen to consider the human body as a property or to associate the body to the person, they have taken very different options. However, an examination of the ways laws are elaborated on this topic shows that these two conceptions can meet in unexpected manners and that lawmaking can give creative answers to both the problem of protecting the person and to the requirements of biomedical research and healthcare practices.

    The recent engagement of Brazil in the construction and utilization of the International Space Station has motivated several Brazilian research institutions and universities to establish study centers related to Space Sciences. The Pontificia Universidade Catolica do Rio Grande do Sul (PUCRS) is no exception. Method: The University initiated in 1993 the first degree course training students to operate commercial aircraft in South America (the School of Aeronautical Sciences. A further step was the decision to build the first Brazilian laboratory dedicated to the conduct of experiments in ground-based microgravity simulation. Established in 1998, the Microgravity Laboratory, which was located in the Instituto de Pesquisas Cientificas e Tecnologicas (IPCT), was supported by the Schools of Medicine, Aeronautical Sciences and Electrical Engineering/Biomedical Engineering. At the end of 2006, the Microgravity Laboratory became a Center and was transferred to the School of Engineering. Results: The principal activities of the Microgravity Centre are the development of research projects related to human physiology before, during and after ground-based microgravity simulation and parabolic flights, to aviation medicine in the 21st century and to aerospace biomedical engineering. Conclusion: The history of Brazilian, and why not say worldwide, space science should unquestionably go through PUCRS. As time passes, the pioneering spirit of our University in the aerospace area has become undeniable.

    It is widely recognized that the welfare of the most advanced economies is at risk, and that the only way to tackle this situation is by controlling the knowledge economies and dealing with. To achieve this ambitious goal, we need to improve the performance of each dimension in the "knowledge triangle": education, research and innovation. Indeed, recent findings point to the importance of strategies of adding-value and marketing during R+D processes so as to bridge the gap between the laboratory and the market and so ensure the successful commercialization of new technology-based products. Moreover, in a global economy in which conventional manufacturing is dominated by developing economies, the future of industry in the most advanced economies must rely on its ability to innovate in those high-tech activities that can offer a differential added-value, rather than on improving existing technologies and products. It seems quite clear, therefore, that the combination of health (medicine) and nanotechnology in a new biomedical device is very capable of meeting these requisites. This work propose a generic CMOS Front-End Self-Powered In-Vivo Implantable Biomedical Device, based on a threeelectrode amperometric biosensor approach, capable of detecting threshold values for targeted concentrations of pathogens, ions, oxygen concentration, etc. Given the speed with which diabetes can spread, as diabetes is the fastest growing disease in the world, the nano-enabled implantable device for in-vivo biomedical analysis needs to be introduced into the global diabetes care devices market. In the case of glucose monitoring, the detection of a threshold decrease in the glucose level it is mandatory to avoid critic situations like the hypoglycemia. Although the case study reported in this paper is complex because it involves multiple organizations and sources of data, it contributes to extend experience to the best practices and models on nanotechnology applications and

  12. Fluorescent probes and fluorescence (microscopy) techniques--illuminating biological and biomedical research.

    PubMed

    Drummen, Gregor P C

    2012-11-28

    Fluorescence, the absorption and re-emission of photons with longer wavelengths, is one of those amazing phenomena of Nature. Its discovery and utilization had, and still has, a major impact on biological and biomedical research, since it enables researchers not just to visualize normal physiological processes with high temporal and spatial resolution, to detect multiple signals concomitantly, to track single molecules in vivo, to replace radioactive assays when possible, but also to shed light on many pathobiological processes underpinning disease states, which would otherwise not be possible. Compounds that exhibit fluorescence are commonly called fluorochromes or fluorophores and one of these fluorescent molecules in particular has significantly enabled life science research to gain new insights in virtually all its sub-disciplines: Green Fluorescent Protein. Because fluorescent proteins are synthesized in vivo, integration of fluorescent detection methods into the biological system via genetic techniques now became feasible. Currently fluorescent proteins are available that virtually span the whole electromagnetic spectrum. Concomitantly, fluorescence imaging techniques were developed, and often progress in one field fueled innovation in the other. Impressively, the properties of fluorescence were utilized to develop new assays and imaging modalities, ranging from energy transfer to image molecular interactions to imaging beyond the diffraction limit with super-resolution microscopy. Here, an overview is provided of recent developments in both fluorescence imaging and fluorochrome engineering, which together constitute the “fluorescence toolbox” in life science research.

    Social network analysis (SNA) helps us understand patterns of interaction between social entities. A number of SNA studies have shed light on the characteristics of research collaboration networks (RCNs). Especially, in the Clinical Translational Science Award (CTSA) community, SNA provides us a set of effective tools to quantitatively assess research collaborations and the impact of CTSA. However, descriptive network statistics are difficult for non-experts to understand. In this article, we present our experiences of building meaningful network visualizations to facilitate a series of visual analysis tasks. The basis of our design is multidimensional, visual aggregation of network dynamics. The resulting visualizations can help uncover hidden structures in the networks, elicit new observations of the network dynamics, compare different investigators and investigator groups, determine critical factors to the network evolution, and help direct further analyses. We applied our visualization techniques to explore the biomedical RCNs at the University of Arkansas for Medical Sciences--a CTSA institution. And, we created CollaborationViz, an open-source visual analytical tool to help network researchers and administration apprehend the network dynamics of research collaborations through interactive visualization.

    Increasing the college graduation rates of underrepresented minority students in science disciplines is essential to attain a diverse workforce for the 21st century. The Research Internship and Science Education (RISE) program attempts to motivate and prepare students from the Atlanta Public School system, where underrepresented minority (URM) students comprise a majority of the population, for biomedical science careers by offering the opportunity to participate in an original research project. Students work in a research laboratory from the summer of their sophomore year until graduation, mentored by undergraduate and graduate students and postdoctoral fellows (postdocs). In addition, they receive instruction in college-level biology, scholastic assessment test (SAT) preparation classes, and help with the college application process. During the last 4 yr, RISE students have succeeded in the identification and characterization of a series of proteins involved in the regulation of nuclear organization and transcription. All but 1 of 39 RISE students have continued on to 4-year college undergraduate studies and 61% of those students are currently enrolled in science-related majors. These results suggest that the use of research-based experiences at the high school level may contribute to the increased recruitment of underrepresented students into science-related careers.

    The article highlights the career of Professor Mansour Ali Haseeb (1910 - 1973; DKSM, Dip Bact, FRCPath, FRCP [Lond]), a pioneer worker in health, medical services, biomedical research and medical education in the Sudan. After his graduation from the Kitchener School of Medicine (renamed, Faculty of Medicine, University of Khartoum [U of K]) in 1934, he devoted his life for the development of laboratory medicine. He became the first Sudanese Director of Stack Medical Research Laboratories (1952 - 1962). He made valuable contributions by his services in the vaccine production and implementation programs, most notably in combating small pox, rabies and epidemic meningitis. In 1963 he became the first Sudanese Professor of Microbiology and Parasitology and served as the first Sudanese Dean of the Faculty of Medicine, U of K (1963-1969). He was an active loyal citizen in public life and served in various fields outside the medical profession. As Mayor of Omdurman, he was invited to visit Berlin in 1963 by Willy Brandt, Mayor of West Berlin (1957-1966) and Chancellor of the Federal Republic of Germany (1969 to 1974). Also as Mayor of Omdurman, he represented the City in welcoming Queen Elizabeth II during her visit to Sudan in February 1965. He also received State Medals from Egypt and Ethiopia. In 1973 he was appointed Chairman of the Sudan Medical Research Council, and was awarded the international Dr. Shousha Foundation Prize and Medal by the WHO for his contribution in the advancement of health, research and medical services.

    1994-12-31

    When the North Carolina Association for Biomedical Research (NCABR) surveyed the state`s science teachers in March 1993, 92% of those responding requested information related to biomedical research. Most of the teachers requested lesson plans and activities designed to help them give students an accurate and balanced perspective on research. In response to that need, NCABR has recently completed production of a 300-page teacher`s manual that provides an overview of the biomedical research process and describes the role and care of animals in that process. Rx for Science Literacy incorporates background information, lesson plans, handouts and activities to assist teachers in K-12 classrooms. Developed by a science teacher with assistance from science and education experts, the manual captures the complex biomedical research process in an easy-to-follow, easy-to-use format. In North Carolina, NCABR plans to begin these workshops in fall 1994. The workshops will include a tour of a biomedical research laboratory and on-site presentations by bench scientists. Teacher evaluation of the manual will be structured into the workshop program. The manual is available at cost to all interested individuals and organizations.

    Fungal contamination of biomedical processes and facilities can result in major revenue loss and product delay. A biomedical research facility (BRF) culturing human cell lines experienced recurring fungal contamination of clean room incubators over a 3-year period. In 2010, as part of the plan to mitigate contamination, 20 fungal specimens were isolated by air and swab samples at various locations within the BRF. Aspergillus niger and Aspergillus fumigatus were isolated from several clean-room incubators. A. niger and A. fumigatus were identified using sequence comparison of the 18S rRNA gene. To determine whether the contaminant strains isolated in 2010 were the same as or different from strains isolated between 2007 and 2009, a novel forensic approach to random amplified polymorphic DNA (RAPD) PCR was used. The phylogenetic relationship among isolates showed two main genotypic clusters, and indicated the continual presence of the same A. fumigatus strain in the clean room since 2007. Biofilms can serve as chronic sources of contamination; visual inspection of plugs within the incubators revealed fungal biofilms. Moreover, confocal microscopy imaging of flow cell-grown biofilms demonstrated that the strains isolated from the incubators formed dense biofilms relative to other environmental isolates from the BRF. Lastly, the efficacies of various disinfectants employed at the BRF were examined for their ability to prevent spore germination. Overall, the investigation found that the use of rubber plugs around thermometers in the tissue culture incubators provided a microenvironment where A. fumigatus could survive regular surface disinfection. A general lesson from this case study is that the presence of microenvironments harboring contaminants can undermine decontamination procedures and serve as a source of recurrent contamination.

    Objectives To develop a security infrastructure to support controlled and secure access to data and analytical resources in a biomedical research Grid environment, while facilitating resource sharing among collaborators. Design A Grid security infrastructure, called Grid Authentication and Authorization with Reliably Distributed Services (GAARDS), is developed as a key architecture component of the NCI-funded cancer Biomedical Informatics Grid (caBIG™). The GAARDS is designed to support in a distributed environment 1) efficient provisioning and federation of user identities and credentials; 2) group-based access control support with which resource providers can enforce policies based on community accepted groups and local groups; and 3) management of a trust fabric so that policies can be enforced based on required levels of assurance. Measurements GAARDS is implemented as a suite of Grid services and administrative tools. It provides three core services: Dorian for management and federation of user identities, Grid Trust Service for maintaining and provisioning a federated trust fabric within the Grid environment, and Grid Grouper for enforcing authorization policies based on both local and Grid-level groups. Results The GAARDS infrastructure is available as a stand-alone system and as a component of the caGrid infrastructure. More information about GAARDS can be accessed at http://www.cagrid.org. Conclusions GAARDS provides a comprehensive system to address the security challenges associated with environments in which resources may be located at different sites, requests to access the resources may cross institutional boundaries, and user credentials are created, managed, revoked dynamically in a de-centralized manner.

    One of the most important steps in biomedical longitudinal studies is choosing a good experimental design that can provide high accuracy in the analysis of results with a minimum sample size. Several methods for constructing efficient longitudinal designs have been developed based on power analysis and the statistical model used for analyzing the final results. However, development of this technology is not available to practitioners through user-friendly software. In this paper we introduce LADES (Longitudinal Analysis and Design of Experiments Software) as an alternative and easy-to-use tool for conducting longitudinal analysis and constructing efficient longitudinal designs. LADES incorporates methods for creating cost-efficient longitudinal designs, unequal longitudinal designs, and simple longitudinal designs. In addition, LADES includes different methods for analyzing longitudinal data such as linear mixed models, generalized estimating equations, among others. A study of European eels is reanalyzed in order to show LADES capabilities. Three treatments contained in three aquariums with five eels each were analyzed. Data were collected from 0 up to the 12th week post treatment for all the eels (complete design). The response under evaluation is sperm volume. A linear mixed model was fitted to the results using LADES. The complete design had a power of 88.7% using 15 eels. With LADES we propose the use of an unequal design with only 14 eels and 89.5% efficiency. LADES was developed as a powerful and simple tool to promote the use of statistical methods for analyzing and creating longitudinal experiments in biomedical research.

    Scientific reproducibility is key to scientific progress as it allows the research community to build on validated results, protect patients from potentially harmful trial drugs derived from incorrect results, and reduce wastage of valuable resources. The National Institutes of Health (NIH) recently published a systematic guideline titled "Rigor and Reproducibility " for supporting reproducible research studies, which has also been accepted by several scientific journals. These journals will require published articles to conform to these new guidelines. Provenance metadata describes the history or origin of data and it has been long used in computer science to capture metadata information for ensuring data quality and supporting scientific reproducibility. In this paper, we describe the development of Provenance for Clinical and healthcare Research (ProvCaRe) framework together with a provenance ontology to support scientific reproducibility by formally modeling a core set of data elements representing details of research study. We extend the PROV Ontology (PROV-O), which has been recommended as the provenance representation model by World Wide Web Consortium (W3C), to represent both: (a) data provenance, and (b) process provenance. We use 124 study variables from 6 clinical research studies from the National Sleep Research Resource (NSRR) to evaluate the coverage of the provenance ontology. NSRR is the largest repository of NIH-funded sleep datasets with 50,000 studies from 36,000 participants. The provenance ontology reuses ontology concepts from existing biomedical ontologies, for example the Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT), to model the provenance information of research studies. The ProvCaRe framework is being developed as part of the Big Data to Knowledge (BD2K) data provenance project.

    Schistosomiasis remains a health burden in many parts of the world. The complex life cycle of Schistosoma parasites and the economic and societal conditions present in endemic areas make the prospect of eradication unlikely in the foreseeable future. Continued and vigorous research efforts must therefore be directed at this disease, particularly since only a single World Health Organization (WHO)-approved drug is available for treatment. The National Institutes of Health (NIH)–National Institute of Allergy and Infectious Diseases (NIAID) Schistosomiasis Resource Center (SRC) at the Biomedical Research Institute provides investigators with the critical raw materials needed to carry out this important research. The SRC makes available, free of charge (including international shipping costs), not only infected host organisms but also a wide array of molecular reagents derived from all life stages of each of the three main human schistosome parasites. As the field of schistosomiasis research rapidly advances, it is likely to become increasingly reliant on omics, transgenics, epigenetics, and microbiome-related research approaches. The SRC has and will continue to monitor and contribute to advances in the field in order to support these research efforts with an expanding array of molecular reagents. In addition to providing investigators with source materials, the SRC has expanded its educational mission by offering a molecular techniques training course and has recently organized an international schistosomiasis-focused meeting. This review provides an overview of the materials and services that are available at the SRC for schistosomiasis researchers, with a focus on updates that have occurred since the original overview in 2008.

    2001-01-01

    This study uses bibliometric analysis to evaluate scientific biomedical literature published on the territory of Vojvodina and its impact on researchers in Yugoslavia and in the world. The study sample comprised 6.979 publications from the territory of Vojvodina published in the period 1986-1997. The following parameters were determined: productivity of authors and institutions where they were employed and some other bibliometric parameters. The impact of these publications on other researches was analyzed for the same period, by citation analysis of papers published in 3 most eminent medical journals in Yugoslavia (3.440 articles, 58.484 references) and in Science Citation Index. Results of the study revealed that production of biomedical literature on the territory of Vojvodina was at high level. Medical research presented in journals of Vojvodina, which are the carriers of current information and accomplishments in science, technique, and practice in biomedicine, was satisfactory. Biomedical articles published in Vojvodina showed a tendency towards increase in number of authors, whereas the greater number of publications were written by a small number of extremely productive authors and institutions. Biomedical researches in Yugoslavia usually cite only foreign literature, while domestic references are mostly self-citations or citations of older literature. The impact of publications published in Vojvodina on other researchers in Yugoslavia is evident, but it is greatest on the territory where they are published. In regard to biomedical journals from Vojvodina "Medical review" is the most cited journal in Yugoslavia and in SCI. Most of the cited references belong to a small number of authors. Thus, according to bibliometric criteria the impact of medical science and professional practice in Vojvodina on international scientific streems is negligible, as well as the impact of papers published in Vojvodina on researchers in the world.

    Background Community perception in biomedical research remains critical in Africa with many participants being driven by different motives. The objective of this study was to explore the perceived motives for women or females guardians to volunteer for their children to participate in biomedical research and to explore experiences and challenges faced by Community Owned Resource Persons (CORPs) when mobilizing community members to participate in biomedical research. Methods This cross sectional study was conducted in Korogwe district, in north-eastern Tanzania. Qualitative methods combining random and purposive sampling techniques were used for data collection. A randomly selected sample using random table method from the existing list of households in the ward office was used to select participants for Focus Group Discussions (FGDs). A purposive sampling technique was used for In-Depth Interviews (IDIs) with CORPs. Thematic framework analysis was used to analyze the data. Results Need for better health services, availability of qualified clinicians, and better access to services provided at the research points were reported as main motives for community members to participate in biomedical research. With regard to experience and challenges faced by CORPs, the main reasons for mothers and guardians not participating in biomedical research were linked to misconception of the malariometric surveys, negative perception of the validity and sensitivity of rapid diagnostic tests, fear of knowing Human Immunodeficiency Virus Infection (HIV)/Acquired Immune Deficiency Syndrome (HIV/AIDS) sero status, and lack of trust for the medical information provided by the CORPs. Challenges reported by CORPs included lack ofawareness of malariometric surveys among participants, time consumption in mobilization of the community, difficulties in identifying individual results, and family responsibilities. Conclusion This study has shown that majority of community members had positive

    The tree shrews are non-rodent, primate-like, small animals. There is increasing interest in using them to establish animal models for medical and biological research. This review focuses on the use of the tree shrews in in vivo studies on viral hepatitis, hepatocellular carcinoma (HCC), myopia, and psychosocial stress. Because of the susceptibility of the tree shrews (Tupaia belangeri) and their hepatocytes to infection with human hepatitis B virus (HBV) in vivo and in vitro, these animals have been used to establish human hepatitis virus-induced hepatitis and human HBV- and aflatoxin B1-associated HCC models. As these animals are phylogenetically close to primates in evolution and have a well-developed visual system and color vision in some species, they have been utilized to establish myopia models. Because dramatic behavioral, physiological, and neuroendocrine changes in subordinate male tree shrews are similar to those observed in depressed human patients, the tree shrews have been successfully employed to experimentally study psychosocial stress. However, the tree shrews holds significant promise as research models and great use could be made of these animals in biomedical research.

    Electronic laboratory notebooks (ELNs) will probably replace paper laboratory notebooks (PLNs) in academic research due to their advantages in data recording, sharing and security. Despite several reports describing technical characteristics of ELNs and their advantages over PLNs, no study has directly tested ELN performance among researchers. In addition, the usage of tablet-based devices or wearable technology as ELN complements has never been explored in the field. To implement an ELN in our biomedical research institute, here we first present a technical comparison of six ELNs using 42 parameters. Based on this, we chose two ELNs, which were tested by 28 scientists for a 3-month period and by 80 students via hands-on practical exercises. Second, we provide two survey-based studies aimed to compare these two ELNs (PerkinElmer Elements and Microsoft OneNote) and to analyze the use of tablet-based devices. We finally explore the advantages of using wearable technology as ELNs tools. Among the ELNs tested, we found that OneNote presents almost all parameters evaluated (39/42) and both surveyed groups preferred OneNote as an ELN solution. In addition, 80% of the surveyed scientists reported that tablet-based devices improved the use of ELNs in different respects. We also describe the advantages of using OneNote application for Apple Watch as an ELN wearable complement. This work defines essential features of ELNs that could be used to improve ELN implementation and software development.

In addition, 80% of the surveyed scientists reported that tablet-based devices improved the use of ELNs in different respects. We also describe the advantages of using OneNote application for Apple Watch as an ELN wearable complement. This work defines essential features of ELNs that could be used to improve ELN implementation and software development. PMID:27479083

  13. Using a popular science nonfiction book to introduce biomedical research ethics in a biology majors course.

    Although bioethics is an important topic in modern society, it is not a required part of the curriculum for many biology degree programs in the United States. Students in our program are exposed to biologically relevant ethical issues informally in many classes, but we do not have a requirement for a separate bioethics course. The Immortal Life of Henrietta Lacks is a recent nonfiction book that describes the life of the woman whose cervical cancer biopsy gave rise to the HeLa cell line, as well as discussing relevant medical, societal, and ethical issues surrounding human tissue use for research. Weekly reading assignments from the book with discussion questions and a final paper were used to engage students in learning about the ethics of human subjects and human tissues research. Students were surveyed for qualitative feedback on the usefulness of including this book as part of the course. This book has been a successful platform for increasing student knowledge and interest in ethics related to biomedical and biological research.

    Predictions markets are marketplaces for trading contracts with payoffs that depend on the outcome of future events. Popular examples are markets on the outcome of presidential elections, where contracts pay $1 if a specific candidate wins the election and $0 if someone else wins. Contract prices on prediction markets can be interpreted as forecasts regarding the outcome of future events. Further attractive properties include the potential to aggregate private information, to generate and disseminate a consensus among the market participants, and to offer incentives for the acquisition of information. It has been argued that these properties might be valuable in the context of scientific research. In this review, we give an overview of key properties of prediction markets and discuss potential benefits for science. To illustrate these benefits for biomedical research, we discuss an example application in the context of decision making in research on the genetics of diseases. Moreover, some potential practical problems of prediction market application in science are discussed, and solutions are outlined.

    Bioinformatics research relies heavily on the ability to discover and correlate data from various sources. The specialization of life sciences over the past decade, coupled with an increasing number of biomedical datasets available through standardized interfaces, has created opportunities towards new methods in biomedical discovery. Despite the popularity of semantic web technologies in tackling the integrative bioinformatics challenge, there are many obstacles towards its usage by non-technical research audiences. In particular, the ability to fully exploit integrated information needs using improved interactive methods intuitive to the biomedical experts. In this report we present ReVeaLD (a Real-time Visual Explorer and Aggregator of Linked Data), a user-centered visual analytics platform devised to increase intuitive interaction with data from distributed sources. ReVeaLD facilitates query formulation using a domain-specific language (DSL) identified by biomedical experts and mapped to a self-updated catalogue of elements from external sources. ReVeaLD was implemented in a cancer research setting; queries included retrieving data from in silico experiments, protein modeling and gene expression. ReVeaLD was developed using Scalable Vector Graphics and JavaScript and a demo with explanatory video is available at http://www.srvgal78.deri.ie:8080/explorer. A set of user-defined graphic rules controls the display of information through media-rich user interfaces. Evaluation of ReVeaLD was carried out as a game: biomedical researchers were asked to assemble a set of 5 challenge questions and time and interactions with the platform were recorded. Preliminary results indicate that complex queries could be formulated under less than two minutes by unskilled researchers. The results also indicate that supporting the identification of the elements of a DSL significantly increased intuitiveness of the platform and usability of semantic web technologies by domain users.

  18. Caring for nonhuman primates in biomedical research facilities: scientific, moral and emotional considerations.

    PubMed

    Coleman, Kristine

    2011-03-01

    Animal care for nonhuman primates (NHPs) in biomedical facilities has undergone major changes in the past few decades. Today, most primate facilities have dedicated and highly trained animal care technicians who go to great efforts to ensure the physiological and psychological well being of the primates in their charge. These caretakers work closely with the animals and, as a result, often develop strong relationships with them. Once discouraged and considered a potential threat to scientific objectivity, such positive relationships are now seen as important components to animal care. Positive interactions between caretakers and primates can benefit the primates by reducing their stress and improving their overall well being which can, in turn, help the scientific endeavor. Further, providing the best possible care is our moral responsibility. However, there can also be emotional costs associated with caring for NHPs in research facilities, particularly when animals become ill or have to be euthanized. Facilities can do much to help ease this conflict. High-quality and conscientious animal care is good for the animals, science, and public perception of research facilities.

    Biomedical research usually requires combining large volumes of data from multiple heterogeneous sources. Such heterogeneity makes difficult not only the generation of research-oriented dataset but also its exploitation. In recent years, the Open Data paradigm has proposed new ways for making data available in ways that sharing and integration are facilitated. Open Data approaches may pursue the generation of content readable only by humans and by both humans and machines, which are the ones of interest in our work. The Semantic Web provides a natural technological space for data integration and exploitation and offers a range of technologies for generating not only Open Datasets but also Linked Datasets, that is, open datasets linked to other open datasets. According to the Berners-Lee's classification, each open dataset can be given a rating between one and five stars attending to can be given to each dataset. In the last years, we have developed and applied our SWIT tool, which automates the generation of semantic datasets from heterogeneous data sources. SWIT produces four stars datasets, given that fifth one can be obtained by being the dataset linked from external ones. In this paper, we describe how we have applied the tool in two projects related to health care records and orthology data, as well as the major lessons learned from such efforts.

    2012-01-01

    Introduction The severe need for constructing replacement tissues in organ transplanta-tion has necessitated the development of tissue engineering approaches and bioreactors that can bring these approaches to reality. The inherent limitations of conventional bioreactors in generating realistic tissue constructs led to the devise of the microgravity tissue engineering that uses Rotating Wall Vessel (RWV) bioreactors initially developed by NASA. Methods In this review article, we intend to highlight some major advances and accomplishments in the rapidly-growing field of tissue engineering that could not be achieved without using microgravity. Results Research is now focused on assembly of 3 dimensional (3D) tissue fragments from various cell types in human body such as chon-drocytes, osteoblasts, embryonic and mesenchymal stem cells, hepatocytes and pancreas islet cells. Hepatocytes cultured under microgravity are now being used in extracorporeal bioartificial liver devices. Tissue constructs can be used not only in organ replacement therapy, but also in pharmaco-toxicology and food safety assessment. 3D models of vari-ous cancers may be used in studying cancer development and biology or in high-throughput screening of anticancer drug candidates. Finally, 3D heterogeneous assemblies from cancer/immune cells provide models for immunotherapy of cancer. Conclusion Tissue engineering in (simulated) microgravity has been one of the stunning impacts of space research on biomedical sciences and their applications on earth. PMID:23678438

  1. The reincarnation of a biomedical researcher: from bench science to medical education.

    PubMed

    Brawer, James R

    2008-02-01

    After 33 years as a biomedical research scientist, I embarked on a new career in medical education. The transformation was awkward, difficult and exciting. Although I had assumed that previous experience in research and scholarship would stand me in good stead, such was hardly the case. I had to learn to navigate a strange new literature, replete with terms that I did not understand, and to deal with concepts that challenged my physico-chemical mindset. As I learned, I found myself discovering a field rich in essential questions, controversial hypotheses, and important potential applications. With my newly acquired knowledge and skills, I began to reflect on my own educational endeavors. I identified a number of outstanding issues and I designed studies to address them. What made these investigations particularly significant for me was their applicability. Although medical education is an exciting and meaningful career path, because of its low profile in most medical schools, few faculty are aware of the academic opportunities that it affords.

    2008-12-01

    Physiology as a discipline is uniquely positioned to engage undergraduate students in interdisciplinary research in response to the 2006-2011 National Science Foundation Strategic Plan call for innovative transformational research, which emphasizes multidisciplinary projects. To prepare undergraduates for careers that cross disciplinary boundaries, students need to practice interdisciplinary communication in academic programs that connect students in diverse disciplines. This report surveys policy documents relevant to this emphasis on interdisciplinary training and suggests a changing role for physiology courses in bioscience and engineering programs. A role for a physiology course is increasingly recommended for engineering programs, but the study of physiology from an engineering perspective might differ from the study of physiology as a basic science. Indeed, physiology laboratory courses provide an arena where biomedical engineering and bioscience students can apply knowledge from both fields while cooperating in multidisciplinary teams under specified technical constraints. Because different problem-solving approaches are used by students of engineering and bioscience, instructional innovations are needed to break down stereotypes between the disciplines and create an educational environment where interdisciplinary teamwork is used to bridge differences.

    The American Occupational Therapy Association's Centennial Vision articulates the strategic goals for the profession to be science driven and evidence based in major practice areas. In the practice area of productive aging, a previous review of research published in the American Journal of Occupational Therapy (AJOT) found mostly basic research with far fewer effectiveness studies. The current review article is divided into two parts. Part 1 provides an update on the types of research published on productive aging in AJOT in the past 2 yr (2009-2010). Part 2 examines the range and scope of occupational therapy effectiveness research on productive aging published in a similar time frame in other occupational therapy journals and outside of the discipline.

    Background Statistical shape models are widely used in biomedical research. They are routinely implemented for automatic image segmentation or object identification in medical images. In these fields, however, the acquisition of the large training datasets, required to develop these models, is usually a time-consuming process. Even after this effort, the collections of datasets are often lost or mishandled resulting in replication of work. Objective To solve these problems, the Virtual Skeleton Database (VSD) is proposed as a centralized storage system where the data necessary to build statistical shape models can be stored and shared. Methods The VSD provides an online repository system tailored to the needs of the medical research community. The processing of the most common image file types, a statistical shape model framework, and an ontology-based search provide the generic tools to store, exchange, and retrieve digital medical datasets. The hosted data are accessible to the community, and collaborative research catalyzes their productivity. Results To illustrate the need for an online repository for medical research, three exemplary projects of the VSD are presented: (1) an international collaboration to achieve improvement in cochlear surgery and implant optimization, (2) a population-based analysis of femoral fracture risk between genders, and (3) an online application developed for the evaluation and comparison of the segmentation of brain tumors. Conclusions The VSD is a novel system for scientific collaboration for the medical image community with a data-centric concept and semantically driven search option for anatomical structures. The repository has been proven to be a useful tool for collaborative model building, as a resource for biomechanical population studies, or to enhance segmentation algorithms. PMID:24220210

    Scientific reproducibility has been at the forefront of many news stories and there exist numerous initiatives to help address this problem. We posit that a contributor is simply a lack of specificity that is required to enable adequate research reproducibility. In particular, the inability to uniquely identify research resources, such as antibodies and model organisms, makes it difficult or impossible to reproduce experiments even where the science is otherwise sound. In order to better understand the magnitude of this problem, we designed an experiment to ascertain the “identifiability” of research resources in the biomedical literature. We evaluated recent journal articles in the fields of Neuroscience, Developmental Biology, Immunology, Cell and Molecular Biology and General Biology, selected randomly based on a diversity of impact factors for the journals, publishers, and experimental method reporting guidelines. We attempted to uniquely identify model organisms (mouse, rat, zebrafish, worm, fly and yeast), antibodies, knockdown reagents (morpholinos or RNAi), constructs, and cell lines. Specific criteria were developed to determine if a resource was uniquely identifiable, and included examining relevant repositories (such as model organism databases, and the Antibody Registry), as well as vendor sites. The results of this experiment show that 54% of resources are not uniquely identifiable in publications, regardless of domain, journal impact factor, or reporting requirements. For example, in many cases the organism strain in which the experiment was performed or antibody that was used could not be identified. Our results show that identifiability is a serious problem for reproducibility. Based on these results, we provide recommendations to authors, reviewers, journal editors, vendors, and publishers. Scientific efficiency and reproducibility depend upon a research-wide improvement of this substantial problem in science today. PMID:24032093

    The question when and to what extent academic research can benefit society is of great interest to policy-makers and the academic community. Physicians in university hospitals represent a highly relevant test-group for studying the link between research and practice because they engage in biomedical academic research while also providing medical care of measurable quality. Physicians’ research contribution to medical practice can be driven by either high-volume or high-quality research productivity, as often pursuing one productivity strategy excludes the other. To empirically examine the differential contribution to medical practice of the two strategies, we collected secondary data on departments across three specializations (Cardiology, Oncology and Orthopedics) in 50 U.S.-based university hospitals served by 4,330 physicians. Data on volume and quality of biomedical research at each department was correlated with publicly available ratings of departments’ quality of care, demonstrating that high-quality research has significantly greater contribution to quality of care than high-volume research.

    2006-01-01

    As a rule, transgenic animals are being used in in vivo experiments to examine gene functions, their regulation or the contribution of genetic alterations to the development of diseases. Many transgenic animals already are affected in their wellbeing due to the genetic modification alone regardless of the procedures performed with them. Moreover, it is to be questioned whether the experimental use of transgenic animals led to results that were of such outstanding scientific relevance that they legitimated the suffering of the animals. In order to point to possible approaches to avoiding the use of transgenic animals in the areas of research identified, subsequent investigations aimed at collecting information on non-animal test methods that might be applied in pursuing the aforesaid questions. In particular, these were non-animal test methods that make use of genetic techniques. Amongst these are in vitro cell culture methods with genetically modified cells, such as the so called Transfected Cell Array, as well as in vitro test methods, in which specifically targeted genes can be turned on or off selectively for example by the so-called RNA interference technique or by antisense oligonucleotide genes. Since such technologies can also be applied to cell cultures with human cells, investigations with these methods enable direct information on the function of human genes. Even though a one to one replacement of animal experiments with transgenic animals by non-animal test methods is considered unlikely, from the point of view of animal welfare the broad spectrum of already available non animal test methods with which to study the function of genes and genetically caused pathophysiological reactions proves that waiving of animal tests with transgenic animals is possible without impeding biomedical research. Even if it cannot be totally excluded that some very specific questions linked to the respective animal experiment might not be pursued for the time being

    Even though the inevitable process of aging by itself cannot be considered a disease, it is directly linked to life span and is the driving force behind all age-related diseases. It is an undisputable fact that age-associated diseases are among the leading causes of death in the world, primarily in industrialized countries. During the last several years, an intensive search of antiaging treatments has led to the discovery of a variety of drugs that promote health span and/or life extension. The biguanide compound metformin is widely used for treating people with type 2 diabetes and appears to show protection against cancer, inflammation, and age-related pathologies. Here, we summarize the recent developments about metformin use in translational aging research and discuss its role as a potential geroprotector.

    2017-01-01

    Studies with low statistical power increase the likelihood that a statistically significant finding represents a false positive result. We conducted a review of meta-analyses of studies investigating the association of biological, environmental or cognitive parameters with neurological, psychiatric and somatic diseases, excluding treatment studies, in order to estimate the average statistical power across these domains. Taking the effect size indicated by a meta-analysis as the best estimate of the likely true effect size, and assuming a threshold for declaring statistical significance of 5%, we found that approximately 50% of studies have statistical power in the 0–10% or 11–20% range, well below the minimum of 80% that is often considered conventional. Studies with low statistical power appear to be common in the biomedical sciences, at least in the specific subject areas captured by our search strategy. However, we also observe evidence that this depends in part on research methodology, with candidate gene studies showing very low average power and studies using cognitive/behavioural measures showing high average power. This warrants further investigation. PMID:28386409

    This report provides practical recommendations for the design and execution of multicenter functional MRI (MC-fMRI) studies based on the collective experience of the Function Biomedical Informatics Research Network (FBIRN). The study was inspired by many requests from the fMRI community to FBIRN group members for advice on how to conduct MC-fMRI studies. The introduction briefly discusses the advantages and complexities of MC-fMRI studies. Prerequisites for MC-fMRI studies are addressed before delving into the practical aspects of carefully and efficiently setting up a MC-fMRI study. Practical multisite aspects include: (i) establishing and verifying scan parameters including scanner types and magnetic fields, (ii) establishing and monitoring of a scanner quality program, (iii) developing task paradigms and scan session documentation, (iv) establishing clinical and scanner training to ensure consistency over time, (v) developing means for uploading, storing, and monitoring of imaging and other data, (vi) the use of a traveling fMRI expert, and (vii) collectively analyzing imaging data and disseminating results. We conclude that when MC-fMRI studies are organized well with careful attention to unification of hardware, software and procedural aspects, the process can be a highly effective means for accessing a desired participant demographics while accelerating scientific discovery.

    The quest for a cure for HIV remains a timely and key challenge for the HIV research community. Despite significant scientific advances, current HIV therapy regimens do not completely eliminate the negative impact of HIV on the immune system; and the economic impact of treating all people infected with HIV globally, for the duration of their lifetimes, presents significant challenges. This article discusses, from a multidisciplinary approach, critical social, behavioral, ethical, and economic issues permeating the HIV-cure research agenda. As part of a search for an HIV cure, both the perspective of patients/participants and clinical researchers should be taken into account. In addition, continued efforts should be made to involve and educate the broader community.

    Translational research is conducted to achieve a predefined set of economic or societal goals. As a result, investment decisions on where available resources have the highest potential in achieving these goals have to be made. In this paper, we first describe how multicriteria decision analysis can assist in defining the decision context and in ensuring that all relevant aspects of the decision problem are incorporated in the decision making process. We then present the results of a case study to support priority setting in a translational research consortium aimed at reducing the burden of disease of type 2 diabetes. During problem structuring, we identified four research alternatives (primary, secondary, tertiary microvascular, and tertiary macrovascular prevention) and a set of six decision criteria. Scoring of these alternatives against the criteria was done using a combination of expert judgement and previously published data. Lastly, decision analysis was performed using stochastic multicriteria acceptability analysis, which allows for the combined use of numerical and ordinal data. We found that the development of novel techniques applied in secondary prevention would be a poor investment of research funds. The ranking of the remaining alternatives was however strongly dependent on the decision maker's preferences for certain criteria. PMID:26495288

  19. Supportive development of functional tissues for biomedical research using the MINUSHEET® perfusion system

    PubMed Central

    2012-01-01

    Functional tissues generated under in vitro conditions are urgently needed in biomedical research. However, the engineering of tissues is rather difficult, since their development is influenced by numerous parameters. In consequence, a versatile culture system was developed to respond the unmet needs. Optimal adhesion for cells in this system is reached by the selection of individual biomaterials. To protect cells during handling and culture, the biomaterial is mounted onto a MINUSHEET® tissue carrier. While adherence of cells takes place in the static environment of a 24 well culture plate, generation of tissues is accomplished in one of several available perfusion culture containers. In the basic version a continuous flow of always fresh culture medium is provided to the developing tissue. In a gradient perfusion culture container epithelia are exposed to different fluids at the luminal and basal sides. Another special container with a transparent lid and base enables microscopic visualization of ongoing tissue development. A further container exhibits a flexible silicone lid to apply force onto the developing tissue thereby mimicking mechanical load that is required for developing connective and muscular tissue. Finally, stem/progenitor cells are kept at the interface of an artificial polyester interstitium within a perfusion culture container offering for example an optimal environment for the spatial development of renal tubules. The system presented here was evaluated by various research groups. As a result a variety of publications including most interesting applications were published. In the present paper these data were reviewed and analyzed. All of the results point out that the cell biological profile of engineered tissues can be strongly improved, when the introduced perfusion culture technique is applied in combination with specific biomaterials supporting primary adhesion of cells.

    Kilicoglu, Halil; Bergler, Sabine

    2008-01-01

    Background Due to the nature of scientific methodology, research articles are rich in speculative and tentative statements, also known as hedges. We explore a linguistically motivated approach to the problem of recognizing such language in biomedical research articles. Our approach draws on prior linguistic work as well as existing lexical resources to create a dictionary of hedging cues and extends it by introducing syntactic patterns. Furthermore, recognizing that hedging cues differ in speculative strength, we assign them weights in two ways: automatically using the information gain (IG) measure and semi-automatically based on their types and centrality to hedging. Weights of hedging cues are used to determine the speculative strength of sentences. Results We test our system on two publicly available hedging datasets. On the fruit-fly dataset, we achieve a precision-recall breakeven point (BEP) of 0.85 using the semi-automatic weighting scheme and a lower BEP of 0.80 with the information gain weighting scheme. These results are competitive with the previously reported best results (BEP of 0.85). On the BMC dataset, using semi-automatic weighting yields a BEP of 0.82, a statistically significant improvement (p <0.01) over the previously reported best result (BEP of 0.76), while information gain weighting yields a BEP of 0.70. Conclusion Our results demonstrate that speculative language can be recognized successfully with a linguistically motivated approach and confirms that selection of hedging devices affects the speculative strength of the sentence, which can be captured reasonably by weighting the hedging cues. The improvement obtained on the BMC dataset with a semi-automatic weighting scheme indicates that our linguistically oriented approach is more portable than the machine-learning based approaches. Lower performance obtained with the information gain weighting scheme suggests that this method may benefit from a larger, manually annotated corpus for

    The remarkable advances in the field of biology in the last decade, specifically in the areas of biochemistry, genetics, genomics, proteomics, and systems biology, have demonstrated how critically important mathematical models and methods are in addressing questions of vital importance for these disciplines. There is little doubt that the need for utilizing and developing mathematical methods for biology research will only grow in the future. The rapidly increasing demand for scientists with appropriate interdisciplinary skills and knowledge, however, is not being reflected in the way undergraduate mathematics and biology courses are structured and taught in most colleges and universities nationwide. While a number of institutions have stepped forward and addressed this need by creating and offering interdisciplinary courses at the juncture of mathematics and biology, there are still many others at which there is little, if any, interdisciplinary interaction between the curricula. This chapter describes an interdisciplinary course and a textbook in mathematical biology developed collaboratively by faculty from Sweet Briar College and the University of Virginia School of Medicine. The course and textbook are designed to provide a bridge between the mathematical and biological sciences at the lower undergraduate level. The course is developed for and is being taught in a liberal arts setting at Sweet Briar College, Virginia, but some of the advanced modules are used in a course at the University of Virginia for advanced undergraduate and beginning graduate students. The individual modules are relatively independent and can be used as stand-alone projects in conventional mathematics and biology courses. Except for the introductory material, the course and textbook topics are based on current biomedical research.

    David Triggle's career as an educator, researcher, essayist and ethicist in many ways has paralleled the post WWII emergence of the "biomedical research ecosystem" that originated in the concept of the "Endless Frontier". In the ensuing 70 years biomedical research has irreparably changed the nature of society with vaccines, the birth control pill and new generations of drugs and biologics to treat infections, sexually transmitted diseases, psychiatric disorders and cardiovascular diseases. These have led to a shift in the population demographic to the elderly and the chronically sick leading to major issues in the provision of effective and affordable healthcare for much of the world's population. In the present article, in addition to providing a brief biography and an appreciation of David Triggle's contributions to science, the authors expand on three topics in which he has had a major interest: improving the quality, reproducibility and relevance of basic biomedical research; declining career opportunities for graduates in an era of decreased funding-the end of the "Endless Frontier"; and the dynamic between the provision for universal healthcare and the dysfunctional, wasteful and politicized systems of the current medical-industrial complex in delivering healthcare.

    The number of large collaborative research networks in mental health is increasing. Training programs are an essential part of them. We critically review the specific implementation of a research training program in a translational Centre for Biomedical Research in Mental Health in order to inform the strategic integration of basic research into clinical practice to have a positive impact in the mental health system and society. Description of training activities, specific educational programs developed by the research network, and challenges on its implementation are examined. The Centre for Biomedical Research in Mental Health has focused on training through different activities which have led to the development of an interuniversity master's degree postgraduate program in mental health research, certified by the National Spanish Agency for Quality Evaluation and Accreditation. Consolidation of training programs within the Centre for Biomedical Research in Mental Health has considerably advanced the training of researchers to meet competency standards on research. The master's degree constitutes a unique opportunity to accomplish neuroscience and mental health research career-building within the official framework of university programs in Spain.

    This report describes the aging research results and recommendations for snubbers used in commercial nuclear power plants. Snubbers are safety-related devices used to restrain undesirable dynamic loads at various piping and equipment locations in nuclear power plants (NPPs). Each snubber must accommodate a plant's normal thermal movements and must be capable of restraining the maximum off-normal dynamic loads, such as a seismic event or a transient, postulated for its specific location. The effects of snubber aging and the factors that contribute to the degradation of their safety performance need to be better understood. Thus, Phase II of Nuclear Plant Aging Research was conducted to enhance the understanding of snubber aging and its consequences. Pacific Northwest Laboratory staff and their subcontractors, Lake Engineering and Wyle Laboratories, visited eight sites (encompassing thirteen plants) to conduct interviews with NPP staff and to collect data on snubber aging, testing, and maintenance. The Phase II research methodology, evaluation, results, conclusions, and recommendations are described in the report. Effective methods for service-life monitoring of snubbers are included in the recommendations.

    Histochemistry provides the unique opportunity to detect single molecules in the very place where they exert their structural roles or functional activities: this makes it possible to correlate structural organization and function, and may be fruitfully exploited in countless biomedical research topics. Aiming to estimate the impact of histochemical articles in the biomedical field, the last few years citations of articles published in a long-established histochemical journal have been considered. This brief survey suggests that histochemical journals, especially the ones open to a large spectrum of research subjects, do represent an irreplaceable source of information not only for cell biologists, microscopists or anatomists, but also for biochemists, molecular biologists and biotechnologists.

    Aim of this article is to offer an overview of the Open Access strategy and its innovative idea of a free scholarly communication. Following the worldwide debate on the crisis of the scholarly communication and the new opportunities of a networked environment, definitions, purposes and real advantages of the Open Access pathway are presented from a researcher's point of view. To maximize the impact and dissemination, by providing free access to the result of the research, two complementary roads are pointed out and explained self-archiving in open archives and publishing in Open Access journals. To let authors make their choice the most useful tools to find one's way in this new reality are shown: directories, search engines, citation tracking projects. The starting survey being done, the article deals in its conclusions with the Open Access challenges and most debated themes: impact and dissemination, new assessment measures alternative to the Impact Factor, new mandatory policies of the funding agencies, questions related to the copyright issue.

    2014-01-01

    THE DIRECTIVE 2001/20/UE AND THE RESEARCH INVOLVING PATIENTS WITH DOCS: Research involving patients with disorders of consciousness (DOCs) deserves special ethical and legal attention because of its Janus-faced nature. On the one hand, it raises concerns about the risk to expose the involved subjects to disproportionate risks not respecting their individual dignity, particularly their right to be cared for; on the other hand, research is an essential tool in order to improve the clinical condition of patients with DOCs. The present paper concerns the ethical and legal dimensions of biomedical research involving patients with disorders of consciousness. In particular, it focuses on informed consent to experimental treatments, which is a challenging issue both from an ethical and legal point of view. The first part reads the Directive 2001/20/EU in the light of the experimentation of patients with DOCs, and suggests a revision in order to better assess the issue of informed consent. THE PARTICULAR CASE OF INFORMED CONSENT FOR OBSERVATIONAL STUDIES OF NON-COMMUNICATIVE PATIENTS: The second part presents an informed consent form for studies through video-recording of patients unable to communicate their own consent. This form has been elaborated by the bioethics unit of the project "Review of the nosography of vegetative states: application of methods of behavioral analysis to individuals in coma or vegetative state" developed at the Italian National Institute of Health. RELEVANCE OF THE SUGGESTED FORM: The paper describes the conceptual framework of the form for informed consent to studies through video-recoding, which is a relevant example of what issues should be included in an informed consent for any type of studies through video-recording of patients unable to express their own consent.

    The U.S. National Institutes of Health (NIH) annually invests approximately $22 billion in biomedical research through its extramural grant programs. Since fiscal year (FY) 2010, all persons involved in research during the previous project year have been required to be listed on the annual grant progress report. These new data have enabled the production of the first-ever census of the NIH-funded extramural research workforce. Data were extracted from All Personnel Reports submitted for NIH grants funded in FY 2009, including position title, months of effort, academic degrees obtained, and personal identifiers. Data were de-duplicated to determine a unique person count. Person-years of effort (PYE) on NIH grants were computed. In FY 2009, NIH funded 50,885 grant projects, which created 313,049 full- and part-time positions spanning all job functions involved in biomedical research. These positions were staffed by 247,457 people at 2,604 institutions. These persons devoted 121,465 PYE to NIH grant-supported research. Research project grants each supported 6 full- or part-time positions, on average. Over 20% of positions were occupied by postdoctoral researchers and graduate and undergraduate students. These baseline data were used to project workforce estimates for FYs 2010–2014 and will serve as a foundation for future research.—Pool, L. R., Wagner, R. M., Scott, L.

    Simple Summary Biomedical journals have the responsibility to promote humane research. To gauge and evaluate journal policies on animal research, the EXEMPLAR—For “Excellence in Mandatory Policies on Animal Research”—scale is presented and applied to evaluate a sample of 170 biomedical journals, providing an overview of the current landscape of editorial policies on the ethical treatment of animals. Abstract Animal research is not only regulated by legislation but also by self-regulatory mechanisms within the scientific community, which include biomedical journals’ policies on animal use. For editorial policies to meaningfully impact attitudes and practice, they must not only be put into effect by editors and reviewers, but also be set to high standards. We present a novel tool to classify journals’ policies on animal use—the EXEMPLAR scale—as well as an analysis by this scale of 170 journals publishing studies on animal models of three human diseases: Amyotrophic Lateral Sclerosis, Type-1 Diabetes and Tuberculosis. Results show a much greater focus of editorial policies on regulatory compliance than on other domains, suggesting a transfer of journals’ responsibilities to scientists, institutions and regulators. Scores were not found to vary with journals’ impact factor, country of origin or antiquity, but were, however, significantly higher for open access journals, which may be a result of their greater exposure and consequent higher public scrutiny.

    2015-08-01

    A considerable number of studies in epidemiology and biomedicine investigate the etiology of complex diseases by considering (self-identified) race as a relevant variable and focusing on the differences in risk among racial groups in the United States; they extensively draw on a genetic hypothesis--viz. the hypothesis that differences in the risk of complex diseases among racial groups are largely due to genetic differences covarying with genetic ancestry--that appears highly problematic in the light of both current biological evidence and the theory of human genome evolution. Is this reason for dismissing self-identified races? No. An alternative promising use of self-identified races exists, and ironically is suggested by those studies that investigate the etiology of complex diseases without focusing on racial differences. These studies provide a large amount of empirical evidence supporting the primacy of the contribution of non-genetic as opposed to genetic factors to the risk of complex diseases. We show that differences in race--or, better, in racial self-identification--may be critically used as proxies for differences in risk-related exposomes and epigenomes in the context of the United States. Self-identified race is what we need to capture the complexity of the effects of present and past racism on people's health and investigate risk-related external and internal exposures, gene-environment interactions, and epigenetic events. In fact patterns of racial self-identifications on one side, and patterns of risk-related exposomes and epigenomes on the other side, constantly coevolve and tend to match each other. However, there is no guarantee that using self-identified races in epidemiology and biomedical research will be beneficial all things considered: special attention must be paid at balancing positive and negative consequences.

    INVESTIGACION CLINICA was founded by the initiative of Américo Negrette, who became its first editor, and it has been published uninterruptedly since July 1960, with a quarterly frequency. The first issues consisted mainly of a collection of reviews of seminars held at the now called Instituto de Investigaciones Clínicas "Dr. Américo Negrette", Facultad de Medicina, Universidad del Zulia, its publisher. Very soon, original research results from this institution were included in the novel journal. In the 60's, papers on results obtained during the outbreaks of Venezuelan Equine Encephalitis present in the area, were prominent. Originally, the journal published 3-4 papers, but due to the increased number of contributions, in 2001, its format changed from 1/16 to 1/8, and now each number includes 11 original articles. Currently, INVESTIGACION CLINICA publishes 44 papers a year, in Spanish or English on different biomedical topics, from contributors all around the world. Progressively it has been included in different renowned indexes, such as PubMed/MEDLINE, Science Citation Index Expanded, Excerpta Medica, Tropical Diseases Bulletin, Copernicus, Scopus, Periodica, and several others. Besides, it can be found in open access through www.Scielo.org.ve, www.freemedicaljournals.com and in our new Web page: https://sites. google.com/site/revistainvestigacionesclinicas/home. Most papers published in INVESTIGACION CLINICA have been cited in the regional or foreign literature accumulating more than 1200 citations by now. For this particular issue, to celebrate the 50th anniversary of INVESTIGACION CLINICA, we have invited some of our more recent referees or authors to contribute with Reviews in their respective areas of expertise.

    Astronaut missions lasting up to six months aboard the International Space Station (ISS) have much in common with interplanetary flights, especially the outbound, Earth-to-Mars transit portion of a Mars mission. Utilization of ISS and other appropriate platforms to prepare for crewed expeditions to planetary destinations including Mars has been the work of NASA's Human Research Program (HRP) since 2005. HRP is charged specifically to understand and reduced the risks to astronaut health and performance in space exploration missions: everything HRP does and has done is directly related to that responsibility. Two major categories of human research have capitalized on ISS capabilities. The first category centers on the biomedical aspects of long-duration exposure to spaceflight factors, including prolonged weightlessness, radiation exposure, isolation and confinement, and actual risk to life and limb. These studies contribute to astronaut safety, health and efficiency on any long-duration missions, whether in low Earth orbit (LEO) or beyond. Qualitatively, weightlessness is weightlessness, whether in LEO or en route to Mars. The HRP sponsors investigations into losses in muscle and bone integrity, cardiovascular function, sensory-motor capability, immune capacity and psychosocial health, and development and demonstration of appropriate treatments and preventative measures. The second category includes studies that are focused on planetary expeditions beyond LEO. For these, ISS offers a high fidelity analog to investigate the combined effects of spaceflight factors (described above) plus the isolation and autonomy associated with simulated increasing distance from Earth. Investigations address crew cohesion, performance and workload, and mission control performance. The behavioral health and performance and space human factors aspects of planetary missions dominate this category. Work has already begun on a new investigation in this category which will examine the

    The problem of deciding which journal titles to select for acquisition in a biomedical library is modeled. The approach taken is based on cost/benefit ratios. Measures of journal worth, methods of data collection, and journal cost data are considered. The emphasis is on the development of a practical process for selecting journal titles, based on the objectivity and rationality of the model; and on the collection of the approprate data and library statistics in a reasonable manner. The implications of this process towards an overall management information system (MIS) for biomedical serials handling are discussed. PMID:820391

    Objective A mixed-methods study exploring the UK general public's views towards consent for the use of biosamples for biomedical research. Setting Cross-sectional population-based focus groups followed by an online survey. Participants 12 focus groups (81 participants) selectively sampled to reflect a range of demographic groups; 1110 survey responders recruited through a stratified sampling method with quotas set on sex, age, geographical location, socioeconomic group and ethnicity. Main outcome measures (1) Views on the importance of consent when donating residual biosamples for medical research; (2) preferences for opt-in or opt-out consent approaches and (3) preferences for different consent models. Results Participants believed obtaining consent for use of residual biosamples was important as it was ‘morally correct’ to ask, and enabled people to make an active choice and retain control over their biosamples. Survey responders preferred opt-in consent (55%); the strongest predictor was being from a low socioeconomic group (OR 2.22, 95% CI 1.41 to 3.57, p=0.001) and having a religious affiliation (OR 1.36, 95% CI 1.01 to 1.81, p=0.04). Focus group participants had a slight preference for opt-out consent because by using this approach more biosamples would be available and facilitate research. Concerning preferred models of consent for research use of biosamples, survey responders preferred specific consent with recontact for each study for which their biosamples are eligible. Focus group participants preferred generic consent as it provided ‘flexibility for researchers’ and reduced the likelihood that biosamples would be wasted. The strongest predictor for preferring specific consent was preferring opt-in consent (OR 4.58, 95% CI 3.30 to 6.35, p=0.015) followed by non-‘White’ ethnicity (OR 2.94, 95% CI 1.23 to 7.14, p<0.001). Conclusions There is a preference among the UK public for ongoing choice and control over donated biosamples; however
