    2013-06-01

    Predictive processing models of cognition are promising an elegant way to unite action, perception, and learning. However, in the current formulations, they are species-unspecific and have very little particularly human about them. I propose to examine how, in this framework, humans can be able to massively interact and to build shared worlds that are both material and symbolic.

  2. On the human ethology of food sharing

    Full Text Available This paper compares various explanatory concepts of food sharing in humans. In many animal species, parents share food with their offspring, thus investing into the 50% of their own genes present in each child. Even in modern families of industrialised societies, there is a very significant flow of material goods from the parent to the offspring generation. Sharing food between reproductive partners is also easily explainable in evolutionary terms: „food for sex“ as male strategy is observed in some primate species. Sharing within one’s group in small-scale societies can be explained also as consequence of its members being actually rather closely related to each other; this, among others, gives credit to the concept of group selection which gains attention again after having been discarded by classic sociobiology. The ethos of individual and group sharing can quite readily be transferred to larger groups, i.e. a whole nation or, especially in the case of unusually devastating natural disasters, to members of other societies. Food sharing beyond genetic relationship or reproductive interest has been explained as „tit for tat“ and „reciprocal altruism“. Events of give and take, however, are, how the last example demonstrates, quite often non-symmetrical, i.e. one partner shares much more than the other. „Tolerated theft“, a behavioural trait in non-human primate species thought to be a stepping stone for the typical preparedness of humans to share, does not play a big role in traditional societies, which provide an important base to discuss the topic. The Trobriand Islanders, e.g., have a very complex system of sharing. In the years of competitive harvest, their yield of yam is distributed to close relatives, especially to fathers and elder brothers. The donors keep almost nothing for themselves, are however given as well, so that everybody has enough to live. High rank men receive a partly enormous surplus, by which their

  3. Human Beings And Water

    OpenAIRE

    2016-01-01

    The writer of this paper on this writing is talking about the human beings and water. Water is one of the very fundamentally things that human beings need to keep their lives. Human beings sometimes do not realise that the water is very important for them because they actually cannot live their lives without the present of water. Human beings can keep their lives without rice, but cannot without water. For instances the use of water for human beings are domestic use, cooking, washing, bathing...

    In this paper, I examine Jeff McMahan’s arguments for his claim that we are not human organisms, and the arguments of Derek Parfit to the same effect in a recent paper. McMahan uses these arguments to derive conclusions concerning the moral status of embryos and permanent vegetative state (PVS) patients. My claim will be that neither thinker has successfully shown that we are not human beings, and therefore these arguments do not establish the ethical conclusions that McMahan has sought to draw from the arguments in respect of the moral status of embryos and PVS patients.

  6. Shared resource control between human and computer

    Hendler, James; Wilson, Reid

    1989-01-01

    The advantages of an AI system of actively monitoring human control of a shared resource (such as a telerobotic manipulator) are presented. A system is described in which a simple AI planning program gains efficiency by monitoring human actions and recognizing when the actions cause a change in the system's assumed state of the world. This enables the planner to recognize when an interaction occurs between human actions and system goals, and allows maintenance of an up-to-date knowledge of the state of the world and thus informs the operator when human action would undo a goal achieved by the system, when an action would render a system goal unachievable, and efficiently replans the establishment of goals after human intervention.

  7. Could a zygote be a human being?

    Science.gov (United States)

    Burgess, John

    2010-02-01

    This paper re-examines the question of whether quirks of early human foetal development tell against the view (conceptionism) that we are human beings at conception. A zygote is capable of splitting to give rise to identical twins. Since the zygote cannot be identical with either human being it will become, it cannot already be a human being. Parallel concerns can be raised about chimeras in which two embryos fuse. I argue first that there are just two ways of dealing with cases of fission and fusion and both seem to be available to the conceptionist. One is the Replacement View according to which objects cease to exist when they fission or fuse. The other is the Multiple Occupancy View - both twins may be present already in the zygote and both persist in a chimera. So, is the conceptionist position tenable after all? I argue that it is not. A zygote gives rise not only to a human being but also to a placenta - it cannot already be both a human being and a placenta. Neither approach to fission and fusion can help the conceptionist with this problem. But worse is in store. Both fission and fusion can occur before and after the development of the inner cell mass of the blastocyst - the entity which becomes the embryo proper. The idea that we become human beings with the arrival of the inner cell mass leads to bizarre results however we choose to accommodate fission and fusion.

  8. Surgeon unemployment: would practice sharing be a viable solution?

    Wakeam, Elliot; Feinberg, Stan

    2016-04-01

    Surgeon unemployment has become a crisis within Canadian surgery in recent years. Without dedicated governmental workforce planning, ensuring that new residency graduates can find employment will require new models of employment. Practice sharing, whereby a new graduate and a senior surgeon partner to divide their practices, allows the senior surgeon to wind down and the newer surgeon to ramp up. Importantly, this arrangement builds in formal mentoring, which is so important in the early years of starting a surgical practice. Practice sharing may be a solution for the workforce issues currently afflicting new surgical graduates across Canada.

    Full Text Available The achievement of a robust, effective and responsible form of data sharing is currently regarded as a priority for biological and bio-medical research. Empirical evaluations of data sharing may be regarded as an indispensable first step in the identification of critical aspects and the development of strategies aimed at increasing availability of research data for the scientific community as a whole. Research concerning human genetic variation represents a potential forerunner in the establishment of widespread sharing of primary datasets. However, no specific analysis has been conducted to date in order to ascertain whether the sharing of primary datasets is common-practice in this research field. To this aim, we analyzed a total of 543 mitochondrial and Y chromosomal datasets reported in 508 papers indexed in the Pubmed database from 2008 to 2011. A substantial portion of datasets (21.9% was found to have been withheld, while neither strong editorial policies nor high impact factor proved to be effective in increasing the sharing rate beyond the current figure of 80.5%. Disaggregating datasets for research fields, we could observe a substantially lower sharing in medical than evolutionary and forensic genetics, more evident for whole mtDNA sequences (15.0% vs 99.6%. The low rate of positive responses to e-mail requests sent to corresponding authors of withheld datasets (28.6% suggests that sharing should be regarded as a prerequisite for final paper acceptance, while making authors deposit their results in open online databases which provide data quality control seems to provide the best-practice standard. Finally, we estimated that 29.8% to 32.9% of total resources are used to generate withheld datasets, implying that an important portion of research funding does not produce shared knowledge. By making the scientific community and the public aware of this important aspect, we may help popularize a more effective culture of data sharing.

    Cabrera, Laura; Weckert, John

    2013-09-01

    Our technologies have enabled us to change both the world and our perceptions of the world, as well as to change ourselves and to find new ways to fulfil the human desire for improvement and for having new capacities. The debate around using technology for human enhancement has already raised many ethical concerns, however little research has been done in how human enhancement can affect human communication. The purpose of this paper is to explore whether some human enhancements could change our shared lifeworld so radically that human communication as we know it would not be possible any longer. After exploring the kinds of communication problems we are concerned with as well as mentioning some possible enhancement interventions that could bring about such problems, we will address some of the ethical implications that follow from these potential communication problems. We argue that because of the role that communication plays in human society, this issue deserves attention.

    The petroleum industry in Norway is a high-tech locomotive with spin-offs and ripple effects that affect the entire nation. The oil and gas industry is the country's largest source of income. Thanks to its oil and natural gas, Norway has become a rich country, both in terms of money and knowledge. Oil production on the Norwegian Shelf peaked in the summer of 2000 and is now declining. We do not explore as much as we used to, and the activity level is falling. As a professional body and employer's organization for oil companies and supplier firms, one of OLF's most important tasks is to help ensure that the Norwegian Shelf is an attractive area for investment and activities. The industry needs larger exploration areas and competitive framework conditions. Fiscal changes have been proposed that will make it more profitable for the industry to increase exploration activities, while also making it more economical to extract oil and gas from the smaller fields. Measures must be implemented to stimulate more activity and good exploitation of the oil and gas resources in the years to come. On this basis, OLF has commissioned a report on social perspectives concerning the oil and gas activities. The social perspectives report addresses the significance of the petroleum industry for industrial and welfare development in Norway, exploration areas and access to resources, safety, technology and expertise, as well as environmental challenges and coexistence among marine industries. Values must be created before they can be shared. If we are to ensure a high level of welfare for generations yet to come, it is essential that the oil and gas activities last as long as possible (author) (ml)

    Proteomic technologies, such as yeast twohybrid, mass spectrometry (MS), protein/ peptide arrays and fluorescence microscopy, yield multi-dimensional data sets, which are often quite large and either not published or published as supplementary information that is not easily searchable. Without a system in place for standardizing and sharing data, it is not fruitful for the biomedical community to contribute these types of data to centralized repositories. Even more difficult is the annotation and display of pertinent information in the context of the corresponding proteins. Wikipedia, an online encyclopedia that anyone can edit, has already proven quite successful1 and can be used as a model for sharing biological data. However, the need for experimental evidence, data standardization and ownership of data creates scientific obstacles.

    The primary objective of this study is to describe human milk sharing practices in the U.S. Specifically, we examine milk sharing social networks, donor compensation, the prevalence of anonymous milk sharing interactions, recipients' concerns about specific milk sharing risks, and lay screening behaviors. Data on human milk sharing practices were collected via an online survey September 2013-March 2014. Chi-square analyses were used to test the association between risk perception and screening practices. A total of 867 (661 donors, 206 recipients) respondents were included in the analyses. Most (96.1%) reported sharing milk face-to-face. Only 10% of respondents reported giving or receiving milk through a non-profit human milk bank, respectively. There were no reports of anonymous purchases of human milk. A small proportion of recipients (4.0%) reported that their infant had a serious medical condition. Screening of prospective donors was common (90.7%) but varied with social relationship and familiarity. Likewise, concern about specific milk sharing risks was varied, and risk perception was significantly associated (P-values = 0.01 or less) with donor screening for all risk variables except diet. Understanding lay perceptions of milk sharing risk and risk reduction strategies that parents are using is an essential first step in developing public health interventions and clinical practices that promote infant safety.

    Humans are inherently mobile creatures. The way we move around our environment has consequences for a wide range of problems, including the design of efficient transportation systems and the planning of urban areas. Here, we gather data about the position in space and time of about 16 000 individuals who uploaded geo-tagged images from locations within the UK to the Flickr photo-sharing website. Inspired by the theory of Lévy flights, which has previously been used to describe the statistical properties of human mobility, we design a machine learning algorithm to infer the probability of finding people in geographical locations and the probability of movement between pairs of locations. Our findings are in general agreement with official figures in the UK and on travel flows between pairs of major cities, suggesting that online data sources may be used to quantify and model large-scale human mobility patterns.

  19. Algae and humans share a molybdate transporter.

    2011-04-19

    Almost all living organisms need to obtain molybdenum from the external medium to achieve essential processes for life. Activity of important enzymes such as sulfite oxidase, aldehyde oxidase, xanthine dehydrogenase, and nitrate reductase is strictly dependent on the presence of Mo in its active site. Cells take up Mo in the form of the oxianion molybdate, but the molecular nature of the transporters is still not well known in eukaryotes. MOT1 is the first molybdate transporter identified in plant-type eukaryotic organisms, but it is absent in animal genomes. Here we report a molybdate transporter different from the MOT1 family, encoded by the Chlamydomonas reinhardtii gene MoT2, that is also present in animals including humans. The knockdown of CrMoT2 transcription leads to the deficiency of molybdate uptake activity in Chlamydomonas. In addition, heterologous expression in Saccharomyces cerevisiae of MoT2 genes from Chlamydomonas and humans support the functionality of both proteins as molybdate transporters. Characterization of CrMOT2 and HsMOT2 activities showed an apparent Km of about 550 nM that, though higher than the Km reported for MOT1, still corresponds to high affinity systems. CrMoT2 transcription is activated when extracellular molybdate concentration is low but in contrast to MoT1 is not activated by nitrate. Analysis of protein databases revealed the presence of four motifs present in all the proteins with high similarity to MOT2, that label a previously undescribed family of proteins probably related to molybdate transport. Our results open the way toward the understanding of molybdate transport as part of molybdenum homeostasis and Moco biosynthesis in animals.

  20. The Relationship between Humanness and Knowledge Sharing in Malaysia Empirical Evidence from Malaysian Managers

    Full Text Available This paper explores whether there is a relationship between humanness and the willingness to share knowledge in Malaysia. Furthermore, the differences between the Malay, Chinese and Indian ethnicities are researched for the presence of humanness and the willingness to share knowledge. Two hundred and fourteen respondents from privately owned companies participated in this research showing that there is a strong relationship between humanness and knowledge sharing. However, the differences between the three ethnicities are small, which is a surprising finding. It can be concluded that people-oriented managers (one of the ways to express humanness are more willing to share knowledge, and differences between ethnicities have no influence in this matter. From these results, it can be recommended to managers and organizations in Malaysia that they pay more attention and be aware of their management style.Stressing the humanness aspects more as they are described could improve the knowledge transfer within companies.

  3. Can human populations be stabilized?

    Warren, Stephen G.

    2015-02-01

    Historical examples of demographic change, in China, Italy, Nigeria, Utah, Easter Island, and elsewhere, together with simple mathematics and biological principles, show that stabilizing world population before it is limited by food supply will be more difficult than is generally appreciated. United Nations population projections are wrong because they assume, in spite of the absence of necessary feedbacks, that all nations will converge rapidly to replacement-level fertility and thereafter remain at that level. Education of women and provision of contraceptives have caused dramatic reductions in fertility, but many groups, including some that are well-educated, maintain high fertility. Small groups with persistent high fertility can grow to supplant low-fertility groups, resulting in continued growth of the total population. The global average fertility rate could rise even if each country's fertility rate is falling. In some low-fertility European countries where deaths exceed births, the population continues to grow because of immigration. Producing more than two offspring is normal for all animal species with stable populations because their populations are limited by resources or predation rather than birth control. It may therefore be appropriate to view the growth of human population as the result not of excess fertility but rather of excess food.

  4. Building a Shared Definitional Model of Long Duration Human Spaceflight

    In 1956, on the eve of human space travel Strughold first proposed a simple classification of the present and future stages of manned flight that identified key factors, risks and developmental stages for the evolutionary journey ahead. As we look to optimize the potential of the ISS as a gateway to new destinations, we need a current shared working definitional model of long duration human space flight to help guide our path. Initial search of formal and grey literature augmented by liaison with subject matter experts. Search strategy focused on both the use of term long duration mission and long duration spaceflight, and also broader related current and historical definitions and classification models of spaceflight. The related sea and air travel literature was also subsequently explored with a view to identifying analogous models or classification systems. There are multiple different definitions and classification systems for spaceflight including phase and type of mission, craft and payload and related risk management models. However the frequently used concepts of long duration mission and long duration spaceflight are infrequently operationally defined by authors, and no commonly referenced classical or gold standard definition or model of these terms emerged from the search. The categorization (Cat) system for sailing was found to be of potential analogous utility, with its focus on understanding the need for crew and craft autonomy at various levels of potential adversity and inability to gain outside support or return to a safe location, due to factors of time, distance and location.

  5. Human and animal sentinels for shared health risks

    Directory of Open Access Journals (Sweden)

    Peter Rabinowitz, MD, MPH

    2009-03-01

    Full Text Available The tracking of sentinel health events in humans in order to detect and manage disease risks facing a larger population is a well accepted technique applied to influenza, occupational conditions and emerging infectious diseases. Similarly, animal health professionals routinely track disease events in sentinel animal colonies and sentinel herds. The use of animals as sentinels for human health threats, or of humans as sentinels for animal disease risk, dates back at least to the era when coal miners brought caged canaries into mines to provide early warning of toxic gases. Yet the full potential of linking animal and human health information to provide warning of such ‘shared risks’ from environmental hazards has not been realised. Reasons appear to include the professional segregation of human and animal health communities, the separation of human and animal surveillance data and evidence gaps in the linkages between human and animal responses to environmental health hazards. The ‘One Health initiative’ and growing international collaboration in response to pandemic threats, coupled with development in the fields of informatics and genomics, hold promise for improved sentinel event coordination in order to detect and reduce environmental health threats shared between species.

    High-throughput sequencing technology enables population-level surveys of human genomic variation. Here, we examine the joint allele frequency distributions across continental human populations and present an approach for combining complementary aspects of whole-genome, low-coverage data and targeted high-coverage data. We apply this approach to data generated by the pilot phase of the Thousand Genomes Project, including whole-genome 2–4× coverage data for 179 samples from HapMap European, Asian, and African panels as well as high-coverage target sequencing of the exons of 800 genes from 697 individuals in seven populations. We use the site frequency spectra obtained from these data to infer demographic parameters for an Out-of-Africa model for populations of African, European, and Asian descent and to predict, by a jackknife-based approach, the amount of genetic diversity that will be discovered as sample sizes are increased. We predict that the number of discovered nonsynonymous coding variants will reach 100,000 in each population after ∼1,000 sequenced chromosomes per population, whereas ∼2,500 chromosomes will be needed for the same number of synonymous variants. Beyond this point, the number of segregating sites in the European and Asian panel populations is expected to overcome that of the African panel because of faster recent population growth. Overall, we find that the majority of human genomic variable sites are rare and exhibit little sharing among diverged populations. Our results emphasize that replication of disease association for specific rare genetic variants across diverged populations must overcome both reduced statistical power because of rarity and higher population divergence.

    The motor system may rely on a modular organization (muscle synergies activated in time) to execute different tasks. We investigated the common control features of walking and cycling in healthy humans from the perspective of muscle synergies. Three hypotheses were tested: 1) muscle synergies extracted from walking trials are similar to those extracted during cycling; 2) muscle synergies extracted from one of these motor tasks can be used to mathematically reconstruct the electromyographic (EMG) patterns of the other task; 3) muscle synergies of cycling can result from merging synergies of walking. A secondary objective was to identify the speed (and cadence) at which higher similarities emerged. EMG activity from eight muscles of the dominant leg was recorded in eight healthy subjects during walking and cycling at four matched cadences. A factorization technique [nonnegative matrix factorization (NNMF)] was applied to extract individual muscle synergy vectors and the respective activation coefficients behind the global muscular activity of each condition. Results corroborated hypotheses 2 and 3, showing that 1) four synergies from walking and cycling can successfully explain most of the EMG variability of cycling and walking, respectively, and 2) two of four synergies from walking appear to merge together to reconstruct one individual synergy of cycling, with best reconstruction values found for higher speeds. Direct comparison of the muscle synergy vectors of walking and the muscle synergy vectors of cycling (hypothesis 1) produced moderated values of similarity. This study provides supporting evidence for the hypothesis that cycling and walking share common neuromuscular mechanisms.

  8. Data Rights and Responsibilities: A Human Rights Perspective on Data Sharing.

    A human-rights-based analysis can be a useful tool for the scientific community and policy makers as they develop codes of conduct, harmonized standards, and national policies for data sharing. The human rights framework provides a shared set of values and norms across borders, defines rights and responsibilities of various actors involved in data sharing, addresses the potential harms as well as the benefits of data sharing, and offers a framework for balancing competing values. The right to enjoy the benefits of scientific progress and its applications offers a particularly helpful lens through which to view data as both a tool of scientific inquiry to which access is vital and as a product of science from which everyone should benefit.

    Peer milk sharing, the noncommercial sharing of human milk from one parent or caretaker directly to another for the purposes of feeding a child, appears to be an increasing infant-feeding practice. Although the U.S. Food and Drug Administration has issued a warning against the practice, little is known about how people who share human milk handle and store milk and whether these practices are consistent with clinical safety protocols. Research aim: This study aimed to learn about the milk-handling practices of expressed human milk by milk-sharing donors and recipient caretakers. In this article, we explore the degree to which donors and recipients adhere to the Academy of Breastfeeding Medicine clinical recommendations for safe handling and storage. Online surveys were collected from 321 parents engaged in peer milk sharing. Univariate descriptive statistics were used to describe the safe handling and storage procedures for milk donors and recipients. A two-sample t-test was used to compare safety items common to each group. Multivariate ordinary least squares regression analysis was used to examine sociodemographic correlates of milk safety practices within the sample group. Findings indicate that respondents engaged in peer milk sharing report predominantly positive safety practices. Multivariate analysis did not reveal any relationship between safety practices and sociodemographic characteristics. The number of safe practices did not differ between donors and recipients. Parents and caretakers who participate in peer human milk sharing report engaging in practices that should reduce risk of bacterial contamination of expressed peer shared milk. More research on this particular population is recommended.

    There are three main approaches about the question of Human Nature. essentialists consider that there exists a permanent Human Nature, shared by every human being. Existentialists consider that there is no such thing as human nature, but inescapable modes of being in the world. A moderate approach would consider that Human Nature can be modified within the limits of anthropological invariants. Transhumanists are conservative in that they think that there is a Human Nature; but they are radical in that they believe that it can (and must) be transcended by bio-technnologies and computer technologies. This project is evaluated as a caricature of suitable human enhancement.

  13. Modeling cognitive loads for evolving shared mental models in human-agent collaboration.

    2011-04-01

    Recent research on human-centered teamwork highly demands the design of cognitive agents that can model and exploit human partners' cognitive load to enhance team performance. In this paper, we focus on teams composed of human-agent pairs and develop a system called Shared Mental Models for all--SMMall. SMMall implements a hidden Markov model (HMM)-based cognitive load model for an agent to predict its human partner's instantaneous cognitive load status. It also implements a user interface (UI) concept called shared belief map, which offers a synergic representation of team members' information space and allows them to share beliefs. An experiment was conducted to evaluate the HMM-based load models. The results indicate that the HMM-based load models are effective in helping team members develop a shared mental model (SMM), and the benefit of load-based information sharing becomes more significant as communication capacity increases. It also suggests that multiparty communication plays an important role in forming/evolving team SMMs, and when a group of agents can be partitioned into subteams, splitting messages by their load status can be more effective for developing subteam SMMs.

    This study analyzes data sharing regarding mitochondrial, Y chromosomal and autosomal polymorphisms in a total of 162 papers on ancient human DNA published between 1988 and 2013. The estimated sharing rate was not far from totality (97.6% ± 2.1%) and substantially higher than observed in other fields of genetic research (evolutionary, medical and forensic genetics). Both a questionnaire-based survey and the examination of Journals' editorial policies suggest that this high sharing rate cannot be simply explained by the need to comply with stakeholders requests. Most data were made available through body text, but the use of primary databases increased in coincidence with the introduction of complete mitochondrial and next-generation sequencing methods. Our study highlights three important aspects. First, our results imply that researchers' awareness of the importance of openness and transparency for scientific progress may complement stakeholders' policies in achieving very high sharing rates. Second, widespread data sharing does not necessarily coincide with a prevalent use of practices which maximize data findability, accessibility, useability and preservation. A detailed look at the different ways in which data are released can be very useful to detect failures to adopt the best sharing modalities and understand how to correct them. Third and finally, the case of human paleogenetics tells us that a widespread awareness of the importance of Open Science may be important to build reliable scientific practices even in the presence of complex experimental challenges.

    Intensified and extensive data production and data storage are characteristics of contemporary western societies. Health data sharing is increasing with the growth of Information and Communication Technology (ICT) platforms devoted to the collection of personal health and genomic data. However, the sensitive and personal nature of health data poses ethical challenges when data is disclosed and shared even if for scientific research purposes.With this in mind, the Science and Values Working Group of the COST Action CHIP ME 'Citizen's Health through public-private Initiatives: Public health, Market and Ethical perspectives' (IS 1303) identified six core values they considered to be essential for the ethical sharing of health data using ICT platforms. We believe that using this ethical framework will promote respectful scientific practices in order to maintain individuals' trust in research.We use these values to analyse five ICT platforms and explore how emerging data sharing platforms are reconfiguring the data sharing experience from a range of perspectives. We discuss which types of values, rights and responsibilities they entail and enshrine within their philosophy or outlook on what it means to share personal health information. Through this discussion we address issues of the design and the development process of personal health data and patient-oriented infrastructures, as well as new forms of technologically-mediated empowerment.

    Health care organizations can magnify the impact of their community service and other philanthropic activities by implementing programs that create shared value. By definition, shared value is created when an initiative generates benefit for the sponsoring organization while also generating societal and community benefit. Because the programs generate benefit for the sponsoring organizations, the magnitude of any particular initiative is limited only by the market for the benefit and not the resources that are available for philanthropy.In this article we use three initiatives in sectors other than health care to illustrate the concept of shared value. We also present examples of five types of shared value programs that are sponsored by health care organizations: telehealth, worksite health promotion, school-based health centers, green and healthy housing, and clean and green health services. On the basis of the innovativeness of health care organizations that have already implemented programs that create shared value, we conclude that the opportunities for all health care organizations to create positive impact for individuals and communities through similar programs is large, and the limits have yet to be defined.

    This paper presents a shared-control approach for Assistive Mobile Robots (AMR), which depends on the user's ability to navigate a semi-autonomous powered wheelchair, using a sparse and discrete human-machine interface (HMI). This system is primarily intended to help users with severe motor disabilities that prevent them to use standard human-machine interfaces. Scanning interfaces and Brain Computer Interfaces (BCI), characterized to provide a small set of commands issued sparsely, are possible HMIs. This shared-control approach is intended to be applied in an Assisted Navigation Training Framework (ANTF) that is used to train users' ability in steering a powered wheelchair in an appropriate manner, given the restrictions imposed by their limited motor capabilities. A shared-controller based on user characterization, is proposed. This controller is able to share the information provided by the local motion planning level with the commands issued sparsely by the user. Simulation results of the proposed shared-control method, are presented.

    Full Text Available Shift-share analysis of employment as a measuring instrument for human resource management is proposed by this study. The results obtained through this technique can assist human resource management on the macro-level in making informed and strategic decisions regarding future employment practices and trends. This technique is often applied to studies of economic geography, and is illustrated in this article through its application to the estimation of future employment potential of manufacturing industries of South Africa’s Southern District Municipality. The economy in this region is mainly dependent on gold mining, which is declining as gold reserves are becoming depleted. As a result, a large section of the area’s population will be unemployed in future, causing adversity and other development needs. Shift-share analysis provides insight into the shifts of employment in the various sectors over time, as well as insight into the national share effect on employment in the region, including the regional-industrial mix and the competitive share effects. It was found that the sectors with the highest employment creation potential are: transport equipment, wood and paper products, metal products, and furniture. Some suggestions are also made regarding the ways that this information can be utilised in human resource management.

    Full Text Available Abstract During the past two decades, the advent of functional magnetic resonance imaging (fMRI has fundamentally changed our understanding of brain-behavior relationships. However, the data from any one study add only incrementally to the big picture. This fact raises important questions about the dominant practice of performing studies in isolation. To what extent are the findings from any single study reproducible? Are researchers who lack the resources to conduct a fMRI study being needlessly excluded? Is pre-existing fMRI data being used effectively to train new students in the field? Here, we will argue that greater sharing and synthesis of raw fMRI data among researchers would make the answers to all of these questions more favorable to scientific discovery than they are today and that such sharing is an important next step for advancing the field of cognitive neuroscience.

  5. Can listed property shares be a surrogate for direct property investment behaviour?

    Full Text Available The listed property sector in South Africa has grown to a size which could be considered to be a good representation of the income producing property market in general. Stock market listed property investment funds offer the opportunity to compare indirect property investment to direct property investment, which could bridge the gap between irrational investment behaviour and intrinsic asset values. This study investigates the relationship between listed property share prices and the property values in listed property funds. The share prices are correlated with various factors, such as the accounting ratios of the companies, the financial statements of the companies and general economic variables. The outcome of the study is an explanation of the behaviour of listed property shares, and its relationship to the direct property market and the general economy. This would assist in the explanation of market behaviour and provides the opportunity to more accurately predict portfolio asset values, which might be used in the valuation of individual real estate assets.

    Today’s business environment is placing unparalleled demands on organizations to discover ways to operate more efficiently,while quickly responding to changing needs and demands in business and environment. Both new approaches and techniques are needed to meet these demands (Dangayach,2001). So,human resource management needs a long-term strategy and to be corresponding with a company’s business strategy. In other words,human resource management should be more strategic.

    Since forty years and after the (mythical) speech of John F Kennedy, space offers a new frontier for the human odyssey. But, for this enterprise itself, the human person constitutes without any doubt a frontier as delicate to approach than necessary to cross, if we plan to give a continuation to the Apollo missions and the permanent occupation of a station in terrestrial orbit. Without neglecting the impact of the future space programs on philosophies and cultures of the humanity which stays on Earth, we have to pay a special attention to the consequences for the astronauts of long-time and far from Earth missions of exploration. These consequences are in connection with three types of human relation: - First, the relations of the human being with the Earth. How an inhabitant of the Earth will - Then, the relations of the crew members among themselves. Today, we do not know yet - Finally, the relations of the human persons with themselves. How to manage this singular To these three types of question, we are today able to give only partial answers. However, they would not have to be drawn aside : we are conscious of the human responsibility in the success or the failure of the future missions, inhabited or not. In addition, the answers which will offer search on inhabited flights of long duration and at long distance will be able also to help to live better together on the Earth.

  9. Competition over personal resources favors contribution to shared resources in human groups.

    Directory of Open Access Journals (Sweden)

    Jessica L Barker

    Full Text Available Members of social groups face a trade-off between investing selfish effort for themselves and investing cooperative effort to produce a shared group resource. Many group resources are shared equitably: they may be intrinsically non-excludable public goods, such as vigilance against predators, or so large that there is little cost to sharing, such as cooperatively hunted big game. However, group members' personal resources, such as food hunted individually, may be monopolizable. In such cases, an individual may benefit by investing effort in taking others' personal resources, and in defending one's own resources against others. We use a game theoretic "tug-of-war" model to predict that when such competition over personal resources is possible, players will contribute more towards a group resource, and also obtain higher payoffs from doing so. We test and find support for these predictions in two laboratory economic games with humans, comparing people's investment decisions in games with and without the options to compete over personal resources or invest in a group resource. Our results help explain why people cooperatively contribute to group resources, suggest how a tragedy of the commons may be avoided, and highlight unifying features in the evolution of cooperation and competition in human and non-human societies.

    Natural science and human science are identified as the bases of most nursing theories and research programs. Natural science has been disclaimed by Martha Rogers as the philosophy of science that undergirds her work. The question remains, is the science of unitary human beings an interpretive human science? The author explores the works of Rogers through a dialectic with two human scientists' works. Wilhelm Dilthey's works represent the founding or traditional view, and Jurgen Habermas' works represent a contemporary, reconstructionist view. The ways Rogerian thought contributes to human studies but is distinct from traditional and reconstructionist human sciences are illuminated.

    Rogers, Joanna

    1995-01-01

    In this paper the author challenges the prevailing view that contemporary writing in the medical humanities is serving the needs of the various health care disciplines. The current medical humanities literature assumes that physicians are the appropriate target group. This is most notably the case within health care ethics literature. There appears to be an unexamined assumption that physician-centric approaches to clinical ethical decision-making are the standard by which appropriate ethical practice is judged. The author challenges this assumption and addresses the problems that this approach engenders. The medical humanities literature appears to reinforce hierarchical, patriarchal arrangements which are themselves not morally neutral.

    2013-09-01

    An analysis of the variability of the nucleotide sequences in the mitochondrial genome of modern humans, neanderthals, Denisovans, and other primates has shown that there are shared polymorphisms at positions 2758 and 7146 between modern Homo sapiens (in phylogenetic cluster L2'3'4'5'6) and Homo neanderthalensis (in the group of European neanderthals younger than 48000 years). It is suggested that the convergence may be due to adaptive changes in the mitochondrial genomes of modern humans and neanderthals or interspecific hybridization associated with mtDNA recombination.

    Full Text Available In spite of relative prevalence of trafficking in human beings issues in the expert and general public discourse in recent years, recognition of victimization by various specialists that may come across with victims still is being estimated as unsatisfactory. Stereotypes about victims of trafficking in human beings are just one factor that imperils correct and prompt recognition of victims, i.e. victims' identification, as principal prerequisite of their protection and support. Today, there are various efforts to overcome that problem - primarily through the training of professionals and creating the identification guidelines, i.e. lists of indicators of trafficking in human beings victimization; however, these resolves only one part of the problem and reveal some new challenges at the same time.

    Full Text Available The explosion of available microarray data on human cancer increases the urgency for developing methods for effectively sharing this data among clinical cancer investigators. Lack of a smooth interface between the databases and statistical analysis tools limits the potential benefits of sharing the publicly available microarray data. To facilitate the efficient sharing and use of publicly available microarray data among cancer investigators, we have built a BRB-ArrayTools Data Archive including over one hundred human cancer microarray projects for 28 cancer types. Expression array data and clinical descriptors have been imported into BRB-ArrayTools and are stored as BRB-ArrayTools project folders on the archive. The data archive can be accessed from: http://linus.nci.nih.gov/~brb/DataArchive.html Our BRB-ArrayTools data archive and GEO importer represent ongoing efforts to provide effective tools for efficiently sharing and utilizing human cancer microarray data.

  15. A shared representation of the space near oneself and others in the human premotor cortex.

    2013-09-23

    Interactions between people require shared high-level cognitive representations of action goals, intentions, and mental states, but do people also share their representation of space? The human ventral premotor (PMv) and parietal cortices contain neuronal populations coding for the execution and observation of actions, analogous to the mirror neurons identified in monkeys. This neuronal system is tuned to the location of the acting person relative to the observer and the target of the action. Therefore, it can be theorized that the observer's brain constructs a low-level, body-centered representation of the space around others similar to one's own peripersonal space representation. Single-cell recordings have reported that parietal visuotactile neurons discharge for objects near specific parts of a monkey's own body and near the corresponding body parts of another individual. In humans, no neuroimaging study has investigated this issue. Here, we identified neuronal populations in the human PMv that encode the space near both one's own hand and another person's hand. The shared peripersonal space representation could support social interactions by coding sensory events, actions, and cognitive processes in a common spatial reference frame.

  16. The forms trafficking in human beings

    2005-01-01

    Full Text Available Trafficking in human beings is an illegal act which interferes with the order foreseen by international regulations and national laws and endangers the values vital to society. However, all forms of human trafficking are not of the same danger to society and therefore do not represent the same risk, threat or danger to the safety of the state, society or individuals. In this paper, the author tends to classify the existing forms and aspects of trafficking in human beings as a manifestation in security practice in accordance with the level of social endangerment, geographical level of implementation, bio-physical characteristics of the victims, relation of the victim toward the position in which he/she finds himself/herself and the form of exploitation of the victim, including a short description of their most significant characteristics.

    The relative role of the cortical vs trabecular bone in the load-carrying capacity of the proximal femur-a fundamental issue in both basic-science and clinical biomechanics-remains unclear. To gain insight into this issue, we performed micro-CT-based, linear elastic finite element analysis (61.5-micron-sized elements; ~280 million elements per model) on 18 proximal femurs (5M, 13F, ages 61-93 years) to quantify the fraction of frontal-plane bending moment shared by the cortical vs trabecular bone in the femoral neck, as well as the associated spatial distributions of stress. Analyses were performed separately for a sideways fall and stance loading. For both loading modes and across all 18 bones, we found consistent patterns of load-sharing in the neck: most proximally, the trabecular bone took most of the load; moving distally, the cortical bone took increasingly more of the load; and more distally, there was a region of uniform load-sharing, the cortical bone taking the majority of the load. This distal region of uniform load-sharing extended more for fall than stance loading (77 ± 8% vs 51 ± 6% of the neck length for fall vs. stance; mean ± SD) but the fraction of total load taken by the cortical bone in that region was greater for stance loading (88 ± 5% vs. 64 ± 9% for stance vs. fall). Locally, maximum stress levels occurred in the cortical bone distally, but in the trabecular bone proximally. Although the distal cortex showed qualitative stress distributions consistent with the behavior of an Euler-type beam, quantitatively beam theory did not apply. We conclude that consistent and well-delineated regions of uniform load-sharing and load-transfer between the cortical and trabecular bone exist within the femoral neck, the details of which depend on the external loading conditions.

    Human cooperation is a key driving force behind the evolutionary success of our hominin lineage. At the proximate level, biologists and social scientists have identified other-regarding preferences--such as fairness based on egalitarian motives, and altruism--as likely candidates for fostering large-scale cooperation. A critical question concerns the ontogenetic origins of these constituents of cooperative behavior, as well as whether they emerge independently or in an interrelated fashion. The answer to this question will shed light on the interdisciplinary debate regarding the significance of such preferences for explaining how humans become such cooperative beings. We investigated 15-month-old infants' sensitivity to fairness, and their altruistic behavior, assessed via infants' reactions to a third-party resource distribution task, and via a sharing task. Our results challenge current models of the development of fairness and altruism in two ways. First, in contrast to past work suggesting that fairness and altruism may not emerge until early to mid-childhood, 15-month-old infants are sensitive to fairness and can engage in altruistic sharing. Second, infants' degree of sensitivity to fairness as a third-party observer was related to whether they shared toys altruistically or selfishly, indicating that moral evaluations and prosocial behavior are heavily interconnected from early in development. Our results present the first evidence that the roots of a basic sense of fairness and altruism can be found in infancy, and that these other-regarding preferences develop in a parallel and interwoven fashion. These findings support arguments for an evolutionary basis--most likely in dialectical manner including both biological and cultural mechanisms--of human egalitarianism given the rapidly developing nature of other-regarding preferences and their role in the evolution of human-specific forms of cooperation.

  2. A mechanism for frequency modulation in songbirds shared with humans.

    2013-07-03

    In most animals that vocalize, control of fundamental frequency is a key element for effective communication. In humans, subglottal pressure controls vocal intensity but also influences fundamental frequency during phonation. Given the underlying similarities in the biomechanical mechanisms of vocalization in humans and songbirds, songbirds offer an attractive opportunity to study frequency modulation by pressure. Here, we present a novel technique for dynamic control of subsyringeal pressure in zebra finches. By regulating the opening of a custom-built fast valve connected to the air sac system, we achieved partial or total silencing of specific syllables, and could modify syllabic acoustics through more complex manipulations of air sac pressure. We also observed that more nuanced pressure variations over a limited interval during production of a syllable concomitantly affected the frequency of that syllable segment. These results can be explained in terms of a mathematical model for phonation that incorporates a nonlinear description for the vocal source capable of generating the observed frequency modulations induced by pressure variations. We conclude that the observed interaction between pressure and frequency was a feature of the source, not a result of feedback control. Our results indicate that, beyond regulating phonation or its absence, regulation of pressure is important for control of fundamental frequencies of vocalizations. Thus, although there are separate brainstem pathways for syringeal and respiratory control of song production, both can affect airflow and frequency. We hypothesize that the control of pressure and frequency is combined holistically at higher levels of the vocalization pathways.

  3. How not to Imitate a Human Being

    Science.gov (United States)

    Pellen, Luke

    Will a computer ever be able to convince someone that it is human and so pass the Turing Test? Programs that attempt to directly model high-level psychological processes are too rigid and lack flexibility and power. Current programs that attempt to pass the Turing Test work primarily by extracting keywords from user input and regurgitating preprogrammed responses. These programs can hardly be called "intelligent". A much lower-level approach is required in which the goal is not to emulate a human, but to emulate intelligence. Such an approach would attempt to model low-level biological components of the brain using techniques such as feedback, recursion, artificial life, and genetic algorithms.

    The sharing of experiences between patients has become increasingly privileged as a source of knowledge and support in contemporary healthcare. Despite this, relatively little is known about the processes whereby people's experiences become, or fail to become, valued as sources of health-related knowledge in different contexts. Through a secondary analysis of 87 interviews conducted between 2006 and 2008 in the UK with people affected by motor neurone disease (46 interviews) and Parkinson's disease (41 interviews), we explore the identity work involved in turning other people's experiences into 'experiential knowledge' that can be shared between patients. Of particular interest is how the turning of others' experiences into knowledge is presupposed by negotiating a particular type of identity tension - what, drawing on the work of Paul Ricoeur (2003) on metaphor, we refer to as 'being differently the same'. We examine the way in which people living with motor neurone disease and Parkinson's disease spoke of managing this tension as part of the process of accessing and valuing other patients' experiences, both epistemologically and emotionally. Instead of treating others' experiences as a pre-given source of knowledge, we emphasise how experience comes to be embodied and articulated through different media - bodies, speech, text, and images. Moreover, we suggest that paying closer attention to these media provides opportunities for enhancing our understanding of how people with different chronic and/or terminal illnesses use or do not use different forms of peer support - and in particular online ones - as a source of health-related experiential knowledge. Some of the implications of this are discussed in the specific context of people diagnosed with incurable neurodegenerative conditions characterised by visible physical deterioration and associated emotional distress.

    Full Text Available Many public and private sector projects, such as hydropower dams or mines, trigger forced population displacement but fail to resettle people sustainably and instead cause their impoverishment. Social science research has found that one root cause of such failures and of impoverishment is asset dispossession and the insufficient financing of resettlement. Most governments, however, state that (1 compensation alone is sufficient for restoring the income and livelihood of those displaced, and (2 resources to supplement compensation with additional financing are not available. The author critiques and rejects these positions. He offers a theoretical analysis of the limits and flaws of compensation payments for expropriated assets, and argues that resources are available for supplementing compensation with financial investments for resettlers’ development. The sources for supplementary financing are the economic rent (windfall profits generated by natural resource projects such as hydropower or mining and the regular stream of benefits generated by all projects that require resettlement. Further, the author argues that financial investments in resettlers’ welfare are indispensable and that benefit sharing is feasible. Therefore, both should become basic principles of resettlement legislation and practice.

    Full Text Available The idea of «human nature» defended by Ortega y Gasset is as original as opposite to what is usually understood. We are making a mistake if the starting point is to conceive Man as one living being among others. Neither science nor philosophy, while remaining in the Eleatic tradition, can give a clear explanation. Science, because if we look at Man, as he is presented to us, it is impossible to distinguish in him materially from spiritually; his body and his psyche. Philosophy, because the concept of «human nature» is an invention of our reason, a fantasy. That nature doesn’t exist because the being of man is so strange and different from other beings that its consistency is just going to be what it never manages to be. Therefore, it is what happens, a journey, a history that is running within a circumstance. This is my life, and that of everyone.

    Full Text Available Abstract Background The corn smut fungus Ustilago maydis is a well-established model system for molecular phytopathology. In addition, it recently became evident that U. maydis and humans share proteins and cellular processes that are not found in the standard fungal model Saccharomyces cerevisiae. This prompted us to do a comparative analysis of the predicted proteome of U. maydis, S. cerevisiae and humans. Results At a cut off at 20% identity over protein length, all three organisms share 1738 proteins, whereas both fungi share only 541 conserved proteins. Despite the evolutionary distance between U. maydis and humans, 777 proteins were shared. When applying a more stringent criterion (≥ 20% identity with a homologue in one organism over at least 50 amino acids and ≥ 10% less in the other organism, we found 681 proteins for the comparison of U. maydis and humans, whereas the both fungi share only 622 fungal specific proteins. Finally, we found that S. cerevisiae and humans shared 312 proteins. In the U. maydis to H. sapiens homology set 454 proteins are functionally classified and 42 proteins are related to serious human diseases. However, a large portion of 222 proteins are of unknown function. Conclusion The fungus U. maydis has a long history of being a model system for understanding DNA recombination and repair, as well as molecular plant pathology. The identification of functionally un-characterized genes that are conserved in humans and U. maydis opens the door for experimental work, which promises new insight in the cell biology of the mammalian cell.

    2013-06-01

    Full Text Available The recent developments of the Euro crisis reveal the lack of clear or coherent thinking on the part of both the Eurozone finance ministers and the European Commission. The crisis in Cyprus is partly the consequence of decisions made on private sector involvement in the previous Greek bailout, and other such examples may be made. It is time, therefore, to look reality in the face and strengthen the structures of the EMU. The article is devoted to what has been done and what must still be done to make the European banking system more robust and less permeable to crises, and to preserve the single financial market.

    Donor human milk has emerged as the preferred substrate to feed extremely preterm infants, when mother's own milk is unavailable. This article summarizes the clinical data demonstrating the safety, efficacy, and cost-effectiveness of feeding donor human milk to premature babies. It describes the current state of milk banking in North America, as well as other parts of the world, and the differing criteria for donor selection, current pasteurization techniques, and quality control measures. A risk assessment methodology is proposed, which would allow milk banks globally to assess the safety of their process and respond appropriately to differing risk environments.

    Murine models are valuable instruments in defining the pathogenesis of diabetic nephropathy (DN), but they only partially recapitulate disease manifestations of human DN, limiting their utility. To define the molecular similarities and differences between human and murine DN, we performed a cross-species comparison of glomerular transcriptional networks. Glomerular gene expression was profiled in patients with early type 2 DN and in three mouse models (streptozotocin DBA/2, C57BLKS db/db, and eNOS-deficient C57BLKS db/db mice). Species-specific transcriptional networks were generated and compared with a novel network-matching algorithm. Three shared human-mouse cross-species glomerular transcriptional networks containing 143 (Human-DBA STZ), 97 (Human-BKS db/db), and 162 (Human-BKS eNOS(-/-) db/db) gene nodes were generated. Shared nodes across all networks reflected established pathogenic mechanisms of diabetes complications, such as elements of Janus kinase (JAK)/signal transducer and activator of transcription (STAT) and vascular endothelial growth factor receptor (VEGFR) signaling pathways. In addition, novel pathways not previously associated with DN and cross-species gene nodes and pathways unique to each of the human-mouse networks were discovered. The human-mouse shared glomerular transcriptional networks will assist DN researchers in selecting mouse models most relevant to the human disease process of interest. Moreover, they will allow identification of new pathways shared between mice and humans.

  15. Human Being and the Philosophical Discourse

    Full Text Available The hypothesis from which we start our approach is the one according to which the philosophicaldiscourse is a specific way of communicating the reality. The base of the philosophical communication issurprise, doubt, uncertainty, anxiety, all generated by the fundamental interrogations of Kantian origin: Howmuch am I able to know? What do I have to do? What am I allowed to hope? The answers to all thesequestions were set up in philosophical concepts and visions, all of them leading to communication, trying toexpress themselves and make themselves understood. Communicability is the very essence of thephilosophical approach. Actually, communication is a fundamental philosophical attitude as I, in my capacityof human being, live only with the other, in full interaction. On my own I am nothing. Throughout this paperwe find arguments for the idea according to which the philosophical discourse subordinates an art ofgenuinely living and communicating about balance and avoidance of excess, about the ability to assume andovercome, about lucidity and wisdom, about credibility, certainty and truth, about freedom and limitation,about the meaning and value of the human condition.

  16. Will human populations be limited by food?

    Warren, S. G.

    2016-12-01

    Historical examples of demographic change, in China, Italy, Nigeria, Utah, the Philippines, and elsewhere, together with simple mathematics and biological principles, show that stabilizing world population before it is limited by food supply will be more difficult than is generally appreciated. United Nations population projections are based on a logical fallacy in that they assume, in spite of the absence of necessary negative feedbacks, that all nations will converge rapidly to replacement-level fertility and thereafter remain at that level. The benign projections that have resulted from this assumption may have hindered efforts to make availability of birth-control a priority in development-aid. Education of women and provision of contraceptives have caused dramatic reductions in fertility, but many groups, including some that are well-educated, maintain high fertility. Small groups with persistent high fertility can grow to supplant low-fertility groups, resulting in continued growth of the total population. The global average fertility rate could rise even if each country's fertility rate is falling. In some low-fertility European countries where deaths exceed births, the population continues to grow because of immigration. Producing more than two offspring is normal for all animal species with stable populations, because their populations are limited by resources or predation rather than birth control. It may therefore be appropriate to view the growth of human population as the result not of excess fertility but rather of excess food. Even if the fertility rate is maintained far in excess of 2, the population cannot grow if food is limiting. Without the agricultural advances of the 20thcentury, world population could not have grown as it did from 1.7 billion in 1900 to 6 billion in 2000. The food supply may be enhanced in the future by genetic engineering and other innovations, but it may be limited by water shortage, climate change, pollution, and energy

    All human societies have music with a rhythmic "beat," typically produced with percussive instruments such as drums. The set of capacities that allows humans to produce and perceive music appears to be deeply rooted in human biology, but an understanding of its evolutionary origins requires cross-taxa comparisons. We show that drumming by palm cockatoos (Probosciger aterrimus) shares the key rudiments of human instrumental music, including manufacture of a sound tool, performance in a consistent context, regular beat production, repeated components, and individual styles. Over 131 drumming sequences produced by 18 males, the beats occurred at nonrandom, regular intervals, yet individual males differed significantly in the shape parameters describing the distribution of their beat patterns, indicating individual drumming styles. Autocorrelation analyses of the longest drumming sequences further showed that they were highly regular and predictable like human music. These discoveries provide a rare comparative perspective on the evolution of rhythmicity and instrumental music in our own species, and show that a preference for a regular beat can have other origins before being co-opted into group-based music and dance.

  19. Should human beings have sex? Sexual dimorphism and human enhancement.

    Science.gov (United States)

    Sparrow, Robert

    2010-07-01

    Since the first sex reassignment operations were performed, individual sex has come to be, to some extent at least, a technological artifact. The existence of sperm sorting technology, and of prenatal determination of fetal sex via ultrasound along with the option of termination, means that we now have the power to choose the sex of our children. An influential contemporary line of thought about medical ethics suggests that we should use technology to serve the welfare of individuals and to remove limitations on the opportunities available to them. I argue that, if these are our goals, we may do well to move towards a "post sex" humanity. Until we have the technology to produce genuine hermaphrodites, the most efficient way to do this is to use sex selection technology to ensure that only girl children are born. There are significant restrictions on the opportunities available to men, around gestation, childbirth, and breast-feeding, which will be extremely difficult to overcome via social or technological mechanisms for the foreseeable future. Women also have longer life expectancies than men. Girl babies therefore have a significantly more "open" future than boy babies. Resisting the conclusion that we should ensure that all children are born the same sex will require insisting that sexual difference is natural to human beings and that we should not use technology to reshape humanity beyond certain natural limits. The real concern of my paper, then, is the moral significance of the idea of a normal human body in modern medicine.

    Directory of Open Access Journals (Sweden)

    Bennie J. van der Walt

    2017-02-01

    Full Text Available This investigation discusses the question how an older generation should transfer to or share their own worldview with a younger generation. For various reasons this has become a problem today. One is the inability of some of the old guard to share their perspective on and way of life with the youth. Another factor is that the Christian youth of today is strongly influenced by contemporary cultural tendencies, often incompatible with a biblically based worldview. The question how a worldview should be transferred as well as how it should be received is of equal and crucial importance to ensure that an age-old, valuable tradition does not become the living worldview of the dead and the dead worldview of the living. Therefore, answers to the following questions should be found: (1 What is the essence of such a worldview to be shared? (2 Why should it be shared? (3 How should it not be done? (4 What are the prerequisites for effective sharing? (5 What are the typical characteristics of the young receivers, the group today called Generation Y, Me, or the Millennials (those born between about 1980–2000? (6 How should this group of emerging adults receive such a heritage? The abstract above mentions the six questions to be answered by both the older and younger generation when they seriously try to share a Christian worldview. What follows is an attempt to provide answers to these problems.

  4. Human and non-human primate genomes share hotspots of positive selection.

    Directory of Open Access Journals (Sweden)

    David Enard

    2010-02-01

    Full Text Available Among primates, genome-wide analysis of recent positive selection is currently limited to the human species because it requires extensive sampling of genotypic data from many individuals. The extent to which genes positively selected in human also present adaptive changes in other primates therefore remains unknown. This question is important because a gene that has been positively selected independently in the human and in other primate lineages may be less likely to be involved in human specific phenotypic changes such as dietary habits or cognitive abilities. To answer this question, we analysed heterozygous Single Nucleotide Polymorphisms (SNPs in the genomes of single human, chimpanzee, orangutan, and macaque individuals using a new method aiming to identify selective sweeps genome-wide. We found an unexpectedly high number of orthologous genes exhibiting signatures of a selective sweep simultaneously in several primate species, suggesting the presence of hotspots of positive selection. A similar significant excess is evident when comparing genes positively selected during recent human evolution with genes subjected to positive selection in their coding sequence in other primate lineages and identified using a different test. These findings are further supported by comparing several published human genome scans for positive selection with our findings in non-human primate genomes. We thus provide extensive evidence that the co-occurrence of positive selection in humans and in other primates at the same genetic loci can be measured with only four species, an indication that it may be a widespread phenomenon. The identification of positive selection in humans alongside other primates is a powerful tool to outline those genes that were selected uniquely during recent human evolution.

    Timing is a fundamental variable for behavior. However, the mechanisms allowing human and non-human primates to synchronize their actions with periodic events are not yet completely understood. Here we characterize the ability of rhesus monkeys and humans to perceive and maintain rhythms of different paces in the absence of sensory cues or motor actions. In our rhythm task subjects had to observe and then internally follow a visual stimulus that periodically changed its location along a circular perimeter. Crucially, they had to maintain this visuospatial tempo in the absence of movements. Our results show that the probability of remaining in synchrony with the rhythm decreased, and the variability in the timing estimates increased, as a function of elapsed time, and these trends were well described by the generalized law of Weber. Additionally, the pattern of errors shows that human subjects tended to lag behind fast rhythms and to get ahead of slow ones, suggesting that a mean tempo might be incorporated as prior information. Overall, our results demonstrate that rhythm perception and maintenance are cognitive abilities that we share with rhesus monkeys, and these abilities do not depend on overt motor commands.

    Lupus nephritis (LN) is a serious manifestation of systemic lupus erythematosus. Therapeutic studies in mouse LN models do not always predict outcomes of human therapeutic trials, raising concerns about the human relevance of these preclinical models. In this study, we used an unbiased transcriptional network approach to define, in molecular terms, similarities and differences among three lupus models and human LN. Genome-wide gene-expression networks were generated using natural language processing and automated promoter analysis and compared across species via suboptimal graph matching. The three murine models and human LN share both common and unique features. The 20 commonly shared network nodes reflect the key pathologic processes of immune cell infiltration/activation, endothelial cell activation/injury, and tissue remodeling/fibrosis, with macrophage/dendritic cell activation as a dominant cross-species shared transcriptional pathway. The unique nodes reflect differences in numbers and types of infiltrating cells and degree of remodeling among the three mouse strains. To define mononuclear phagocyte-derived pathways in human LN, gene sets activated in isolated NZB/W renal mononuclear cells were compared with human LN kidney profiles. A tissue compartment-specific macrophage-activation pattern was seen, with NF-κB1 and PPARγ as major regulatory nodes in the tubulointerstitial and glomerular networks, respectively. Our study defines which pathologic processes in murine models of LN recapitulate the key transcriptional processes active in human LN and suggests that there are functional differences between mononuclear phagocytes infiltrating different renal microenvironments.

  11. From Planetary Boundaries to national fair shares of the global safe operating space - How can the scales be bridged?

    2016-04-01

    The planetary boundaries framework proposes precautionary quantitative global limits to the anthropogenic perturbation of crucial Earth system processes. In this way, it marks out a planetary 'safe operating space' for human activities. However, decisions regarding resource use and emissions are mostly made at much smaller scales, mostly by (sub-)national and regional governments, businesses, and other local actors. To operationalize the planetary boundaries, they need to be translated into and aligned with targets that are relevant at these smaller scales. In this paper, we develop a framework that addresses the three dimension of bridging across scales: biophysical, socio-economic and ethical, to provide a consistent universally applicable approach for translating the planetary boundaries into national level context-specific and fair shares of the safe operating space. We discuss our findings in the context of previous studies and their implications for future analyses and policymaking. In this way, we help link the planetary boundaries framework to widely- applied operational and policy concepts for more robust strong sustainability decision-making.

  13. Humidity sensation, cockroaches, worms, and humans: are common sensory mechanisms for hygrosensation shared across species?

    2015-08-01

    Although the ability to detect humidity (i.e., hygrosensation) represents an important sensory attribute in many animal species (including humans), the neurophysiological and molecular bases of such sensory ability remain largely unknown in many animals. Recently, Russell and colleagues (Russell J, Vidal-Gadea AG, Makay A, Lanam C, Pierce-Shimomura JT. Proc Natl Acad Sci USA 111: 8269-8274, 2014) provided for the first time neuromolecular evidence for the sensory integration of thermal and mechanical sensory cues which underpin the hygrosensation strategy of an animal (i.e., the free-living roundworm Caenorhabditis elegans) that lacks specific sensory organs for humidity detection (i.e., hygroreceptors). Due to the remarkable similarities in the hygrosensation transduction mechanisms used by hygroreceptor-provided (e.g., insects) and hygroreceptor-lacking species (e.g., roundworms and humans), the findings of Russell et al. highlight potentially universal mechanisms for humidity detection that could be shared across a wide range of species, including humans.

  16. Effect of ancient population structure on the degree of polymorphism shared between modern human populations and ancient hominins.

    Eriksson, Anders; Manica, Andrea

    2012-08-28

    Recent comparisons between anatomically modern humans and ancient genomes of other hominins have raised the tantalizing, and hotly debated, possibility of hybridization. Although several tests of hybridization have been devised, they all rely on the degree to which different modern populations share genetic polymorphisms with the ancient genomes of other hominins. However, spatial population structure is expected to generate genetic patterns similar to those that might be attributed to hybridization. To investigate this problem, we take Neanderthals as a case study, and build a spatially explicit model of the shared history of anatomically modern humans and this hominin. We show that the excess polymorphism shared between Eurasians and Neanderthals is compatible with scenarios in which no hybridization occurred, and is strongly linked to the strength of population structure in ancient populations. Thus, we recommend caution in inferring admixture from geographic patterns of shared polymorphisms, and argue that future attempts to investigate ancient hybridization between humans and other hominins should explicitly account for population structure.

  3. Health as a basic human need: would this be enough?

    Science.gov (United States)

    de Campos, Thana Cristina

    2012-01-01

    Although the value of health is universally agreed upon, its definition is not. Both the WHO and the UN define health in terms of well-being. They advocate a globally shared responsibility that all of us - states, international organizations, pharmaceutical corporations, civil society, and individuals - bear for the health (that is, the well-being) of the world's population. In this paper I argue that this current well-being conception of health is troublesome. Its problem resides precisely in the fact that the well-being conception of health, as an all-encompassing label, does not properly distinguish between the different realities of health and the different demands of justice, which arise in each case. In addressing responsibilities related to the right to health, we need to work with a more differentiated vocabulary, which can account for these different realities. A crucial distinction to bear in mind, for the purposes of moral deliberation and the crafting of political and legal institutions, is the difference between basic and non-basic health needs. This distinction is crucial because we have presumably more stringent obligations and rights in relation to human needs that are basic, as they justify stronger moral claims, than those grounded on non-basic human needs. It is important to keep this moral distinction in mind because many of the world's problems regarding the right to health relate to basic health needs. By conflating these needs with less essential ones, we risk confusing different types of moral claims and weakening the overall case for establishing duties regarding the right to health. There is, therefore, a practical need to reevaluate the current normative conception of health so that it distinguishes, within the broad scope of well-being, between what is basic and what is not. My aim here is to shed light onto this distinction and to show the need for this differentiation. I do so, first, by providing, on the basis of David Miller

    Full Text Available Abstract The human leukocyte antigens (HLAs play important roles in the immune systems to response to various pathogens and disease among individuals. The aim of this study was analyze the HLA allele and haplotype frequencies of Southern East Asian population that show high incidence of nasopharyngeal carcinoma (NPC to evaluate the shared HLA haplotype contribution to NPC susceptibility among the population and analyses the genetic affinities between the population. We collect information of HLA haplotype from our previous study, other published paper, and HLA database in 19 population during 2005 to 2015. Haplotype frequencies were estimated using the maximum likelihood method based on an expectation maximization algorithm with ARLEQUIN v.2.0 software. We also calculated the genetic distance among 19 Southern East Asians based on HLA allele frequency using modified Cavalli-Sforza (DA distance method. Then, a phylogenetic tree was constructed using DISPAN software and principal component analysis (PCA was performed using XLSTAT-PRO software. A33-B58-DR3 haplotype, tightly linked to NPC, was commonly observed in all populations, supporting the high incidence of NPC in the populations. In addition, A2-B46 haplotype also associated with NPC, was also commonly found in several population that may also have a role in the disease development. The conclusion is the HLA haplotype sharing has an important role than the HLA allele sharing. The A33-B58-DR3 haplotype and A2-B46-DR9 haplotype in this study could be related to NPC in the Southern East Asian populations. The observed haplotype needs to be tested in the real patients to confirm the assumption.

  6. Do humans and nonhuman animals share the grouping principles of the iambic-trochaic law?

    de la Mora, Daniela M; Nespor, Marina; Toro, Juan M

    2013-01-01

    The iambic-trochaic law describes humans' tendency to form trochaic groups over sequences varying in pitch or intensity (i.e., the loudest or highest sounds mark group beginnings), and iambic groups over sequences varying in duration (i.e., the longest sounds mark group endings). The extent to which these perceptual biases are shared by humans and nonhuman animals is yet unclear. In Experiment 1, we trained rats to discriminate pitch-alternating sequences of tones from sequences randomly varying in pitch. In Experiment 2, rats were trained to discriminate duration-alternating sequences of tones from sequences randomly varying in duration. We found that nonhuman animals group sequences based on pitch variations as trochees, but they do not group sequences varying in duration as iambs. Importantly, humans grouped the same stimuli following the principles of the iambic-trochaic law (Exp. 3). These results suggest the early emergence of the trochaic rhythmic grouping bias based on pitch, possibly relying on perceptual abilities shared by humans and other mammals, whereas the iambic rhythmic grouping bias based on duration might depend on language experience.

  7. Eight reasons payer interoperability and data sharing are essential in ACOs. Interoperability standards could be a prerequisite to measuring care.

    It makes strategic and business sense for payers and providers to collaborate on how to take substantial cost out of the healthcare delivery system. Acting independently, neither medical groups, hospitals nor health plans have the optimal mix of resources and incentives to significantly reduce costs. Payers have core assets such as marketing, claims data, claims processing, reimbursement systems and capital. It would be cost prohibitive for all but the largest providers to develop these capabilities in order to compete directly with insurers. Likewise, medical groups and hospitals are positioned to foster financial interdependence among providers and coordinate the continuum of patient illnesses and care settings. Payers and providers should commit to reasonable clinical and cost goals, and share resources to minimize expenses and financial risks. It is in the interest of payers to work closely with providers on risk-management strategies because insurers need synergy with ACOs to remain cost competitive. It is in the interest of ACOs to work collaboratively with payers early on to develop reasonable and effective performance benchmarks. Hence, it is essential to have payer interoperability and data sharing integrated in an ACO model.

    Abstract Background Considerable attention has been given by policy makers and researchers to the human resources for health crisis in Africa. However, little attention has been paid to quantifying health facility-level trends in health worker numbers, distribution and workload, despite growing demands on health workers due to the availability of new funds for HIV\\/AIDS control scale-up. This study analyses and reports trends in HIV and non-HIV ambulatory service workloads on clinical staff in urban and rural district level facilities. Methods Structured surveys of health facility managers, and health services covering 2005-07 were conducted in three districts of Zambia in 2008 (two urban and one rural), to fill this evidence gap. Intra-facility analyses were conducted, comparing trends in HIV and non-HIV service utilisation with staff trends. Results Clinical staff (doctors, nurses and nurse-midwives, and clinical officers) numbers and staff population densities fell slightly, with lower ratios of staff to population in the rural district. The ratios of antenatal care and family planning registrants to nurses\\/nurse-midwives were highest at baseline and increased further at the rural facilities over the three years, while daily outpatient department (OPD) workload in urban facilities fell below that in rural facilities. HIV workload, as measured by numbers of clients receiving antiretroviral treatment (ART) and prevention of mother to child transmission (PMTCT) per facility staff member, was highest in the capital city, but increased rapidly in all three districts. The analysis suggests evidence of task sharing, in that staff designated by managers as ART and PMTCT workers made up a higher proportion of frontline service providers by 2007.

  11. Shared human-chimpanzee pattern of perinatal femoral shaft morphology and its implications for the evolution of hominin locomotor adaptations.

    Directory of Open Access Journals (Sweden)

    Naoki Morimoto

    Full Text Available BACKGROUND: Acquisition of bipedality is a hallmark of human evolution. How bipedality evolved from great ape-like locomotor behaviors, however, is still highly debated. This is mainly because it is difficult to infer locomotor function, and even more so locomotor kinematics, from fossil hominin long bones. Structure-function relationships are complex, as long bone morphology reflects phyletic history, developmental programs, and loading history during an individual's lifetime. Here we discriminate between these factors by investigating the morphology of long bones in fetal and neonate great apes and humans, before the onset of locomotion. METHODOLOGY/PRINCIPAL FINDINGS: Comparative morphometric analysis of the femoral diaphysis indicates that its morphology reflects phyletic relationships between hominoid taxa to a greater extent than taxon-specific locomotor adaptations. Diaphyseal morphology in humans and chimpanzees exhibits several shared-derived features, despite substantial differences in locomotor adaptations. Orangutan and gorilla morphologies are largely similar, and likely represent the primitive hominoid state. CONCLUSIONS/SIGNIFICANCE: These findings are compatible with two possible evolutionary scenarios. Diaphyseal morphology may reflect retained adaptive traits of ancestral taxa, hence human-chimpanzee shared-derived features may be indicative of the locomotor behavior of our last common ancestor. Alternatively, diaphyseal morphology might reflect evolution by genetic drift (neutral evolution rather than selection, and might thus be more informative about phyletic relationships between taxa than about locomotor adaptations. Both scenarios are consistent with the hypothesis that knuckle-walking in chimpanzees and gorillas resulted from convergent evolution, and that the evolution of human bipedality is unrelated to extant great ape locomotor specializations.

    The major purpose of this contribution is to illustrate some differential aspects between the human and the animal bodies, in order to understand the main distinctive characteristic of the human being: his or her rationality. Thus, we firstly deal with some considerations about the general anthropological framework in which the human body is going to be analysed. Next, we briefly explain the importance of the body for an adequate understanding of the intimacy and the biographical perspectives of the person. Here we show some examples of the altered human corporality to stress the importance of the relation to oneself and others as a key and fundamental aspect to look at our rational corporality.

  14. Shared and Unique Proteins in Human, Mouse and Rat Saliva Proteomes: Footprints of Functional Adaptation

    Robert C. Karn

    2013-12-01

    Full Text Available The overall goal of our study was to compare the proteins found in the saliva proteomes of three mammals: human, mouse and rat. Our first objective was to compare two human proteomes with very different analysis depths. The 89 shared proteins in this comparison apparently represent a core of highly-expressed human salivary proteins. Of the proteins unique to each proteome, one-half to 2/3 lack signal peptides and probably are contaminants instead of less highly-represented salivary proteins. We recently published the first rodent saliva proteomes with saliva collected from the genome mouse (C57BL/6 and the genome rat (BN/SsNHsd/Mcwi. Our second objective was to compare the proteins in the human proteome with those we identified in the genome mouse and rat to determine those common to all three mammals, as well as the specialized rodent subset. We also identified proteins unique to each of the three mammals, because differences in the secreted protein constitutions can provide clues to differences in the evolutionary adaptation of the secretions in the three different mammals.

    Living with chronic illness is a family affair that involves ongoing changes and challenges in everyday life. When life changes, the environment is important for family health and well-being. The relation between a place and a family is rarely described, and therefore the aim of this study was to explore the meaning of place for family well-being in families living with chronic illness. A qualitative design was chosen. Data were collected by photovoice combined with narrative family research interviews with 10 families living with chronic illness. A phenomenological hermeneutic analysis was used to interpret the data. The results showed that the meaning of place for family well-being in families living with chronic illness can be described as "a shared respite." This main theme included three subthemes: "a place for relief," "a place for reflection," and "a place for re-creation." These results were further understood by means of the concept place security. Feeling well means having place security in these families. Through knowledge about the meaning of place for family well-being, health care personnel can stimulate families living with chronic illness to find respite in places that contribute to well-being, both in familiar and new places.

    To understand the regulation of tissue-specific gene expression, the GTEx Consortium generated RNA-seq expression data for more than thirty distinct human tissues. This data provides an opportunity for deriving shared and tissue specific gene regulatory networks on the basis of co-expression between genes. However, a small number of samples are available for a majority of the tissues, and therefore statistical inference of networks in this setting is highly underpowered. To address this problem, we infer tissue-specific gene co-expression networks for 35 tissues in the GTEx dataset using a novel algorithm, GNAT, that uses a hierarchy of tissues to share data between related tissues. We show that this transfer learning approach increases the accuracy with which networks are learned. Analysis of these networks reveals that tissue-specific transcription factors are hubs that preferentially connect to genes with tissue specific functions. Additionally, we observe that genes with tissue-specific functions lie at the peripheries of our networks. We identify numerous modules enriched for Gene Ontology functions, and show that modules conserved across tissues are especially likely to have functions common to all tissues, while modules that are upregulated in a particular tissue are often instrumental to tissue-specific function. Finally, we provide a web tool, available at mostafavilab.stat.ubc.ca/GNAT, which allows exploration of gene function and regulation in a tissue-specific manner.

    Full Text Available Within conservation, the need to measure the impacts on people from conservation initiatives such as projects and programs is growing, but understanding and measuring the multidimensional impacts on human well-being from conservation initiatives is complex. To understand the constituent components of human well-being and identify which components of well-being are most common, we analyzed 31 known indices for measuring human well-being. We found 11 focal areas shared by two or more indices for measuring human well-being, and the focal areas of living standards, health, education, social cohesion, security, environment, and governance were in at least 14 of the 31 human well-being indices. We examined each of the common focal areas and assessed its relevance to measuring the human well-being impacts of a conservation initiative. We then looked for existing indices that include the relevant focal areas and recommend the use of Stiglitz et al. (2009—a framework designed to measure economic performance and social progress—as a starting place for understanding and selecting human well-being focal areas suitable for measuring the impacts on people from a conservation initiative.

    Full Text Available Abstract Background Glutaminyl cyclase (QC forms the pyroglutamyl residue at the amino terminus of numerous secretory peptides and proteins. We previously proposed the mammalian QC has some features in common with zinc aminopeptidases. We now have generated a structural model for human QC based on the aminopeptidase fold (pdb code 1AMP and mutated the apparent active site residues to assess their role in QC catalysis. Results The structural model proposed here for human QC, deposited in the protein databank as 1MOI, is supported by a variety of fold prediction programs, by the circular dichroism spectrum, and by the presence of the disulfide. Mutagenesis of the six active site residues present in both 1AMP and QC reveal essential roles for the two histidines (140 and 330, QC numbering and the two glutamates (201 and 202, while the two aspartates (159 and 248 appear to play no catalytic role. ICP-MS analysis shows less than stoichiometric zinc (0.3:1 in the purified enzyme. Conclusions We conclude that human pituitary glutaminyl cyclase and bacterial zinc aminopeptidase share a common fold and active site residues. In contrast to the aminopeptidase, however, QC does not appear to require zinc for enzymatic activity.

    2016-02-01

    Full Text Available The Human Toxome Project is part of a long-term vision to modernize toxicity testing for the 21st century. In the initial phase of the project, a consortium of six academic, commercial, and government organizations has partnered to map pathways of toxicity, using endocrine disruption as a model hazard. Experimental data is generated at multiple sites, and analyzed using a range of computational tools. While effectively gathering, managing, and analyzing the data for high-content experiments is a challenge in its own right, doing so for a growing number of -omics technologies, with larger data sets, across multiple institutions complicates the process. Interestingly, one of the most difficult, ongoing challenges has been the computational collaboration between the geographically separate institutions. Existing solutions cannot handle the growing heterogeneous data, provide a computational environment for consistent analysis, accommodate different workflows, and adapt to the constantly evolving methods and goals of a research project. To meet the needs of the project, we have created and managed The Human Toxome Collaboratorium, a shared computational environment hosted on third-party cloud services. The Collaboratorium provides a familiar virtual desktop, with a mix of commercial, open-source, and custom-built applications. It shares some of the challenges of traditional information technology, but with unique and unexpected constraints that emerge from the cloud. Here we describe the problems we faced, the current architecture of the solution, an example of its use, the major lessons we learned, and the future potential of the concept. In particular, the Collaboratorium represents a novel distribution method that could increase the reproducibility and reusability of results from similar large, multi-omic studies.

  5. Universality of Man as a Cultural and Historical Human Being

    2012-01-01

    Full Text Available On the grounds of theoretical synthesis, the paper reveals the phenomenon of human being in its creative dimension. The present research is aimed at exploring the prospective opportunities for academic processes. The basics of universal essence of man as a cultural historic being with unlimited potential of self- development are defined; the man being mirrored by the basic philosophic concepts: naturalistic, orthodox-oriented, bio-social or bio-socio-cultural. There are two opposing views on human nature: the anthropological essentialism holding that individuality is predetermined by essence; and the anthropological existentialism claiming the opposite – human existence precedes the essentiality, the latter being constituted by the acts of choice, self-development and self-responsibility for personal choice and projecting. In the first case, the subjective side of human existence is ignored, while in the second – the objective socially conditioned side is left behind. Both theories are antihistorical as it is the history that conditions the essence of man according to the ancestral determination, the latter being modified by way of human activity and communication in a particular historical period. The components of human universal essence are defined as follows: possession of organic body, social heritage, free will, self-activity, creativity, social and rational human nature, absence of antagonistic programs of social behavior. According to the author, for the adequate realization of human universality, it is necessary to move from the profit oriented speculative market economy to the creative one oriented on social effectiveness, quality of life and reproduction of wholesome individuals. The research output can be used for devising the methodology of philosophic and pedagogic anthropology, as well as pedagogic practices of teaching philosophy and pedagogic theory in higher school.

    Full Text Available Abstract This article entitled" "I" as most important motivation of Human being" want to consider the main source of all human behaviors. This article aims to answer the question that what causes values or anti-values and also new ideas, giving meanings and human attitudes to be created? Where is the source of human activity and inactivity? Despite the diversity of human behaviors and actions of various origins it seems that one and same origin for all of them can be considered and it is self-preservation. Of course, self-preservation is a general principle for all living creatures.Calling it "self-preservation" in this writing, therefore I say that it is most important motivation of human behavior (whether active or passive behavior. Therefore, "I" is present everywhere with us and that is the creator of happiness and sadness. Thus, all our social and cultural behaviors in our society emanate from it and there will be always "selfishness" in society.

    Host and/or viral factors involved in human polyomavirus (HPoV) infection in persons living with HIV remain unknown. A hypothesis is outlined suggesting the importance of the co-receptors CCR5, CCR2, and CXCR4 not only for HIV, but also for HPoV. Functionally capable receptors coded by wild-type (wt) genotypes could facilitate internalization of HPoV in the cell resulting in brain and/or kidney infection/s in HIV infected individuals. Forty-nine Bulgarians with HIV, all treated by HAART, without neurological and/or kidney disorders, were tested for JCV and BKV and genotyped for CCR5 (CCR5del32), CCR2 (CCR2-64I), and CXCR4 (SDF1-3'A). In 27/49 (55.1%) individuals a co-infection with HPoV was identified-BKV in 12/49 (24.5%), JCV-in another 12/49 (24.5%), and both viruses-in 3/49 (6.1%). A high frequency of wt CCR5 was found in patients with HPoV (91.7% for BKV and JCV and in 100% with both viruses). V/V of CCR2 was presented in 75% for BKV and JCV and in 66.7% for BKV plus JCV. SDF1-3'G/G predominated in JCV infected patients (75%), while G/A and A/A genotypes were more frequent in patients with BKV (41.7%). Also, 21/22 (95.4%) persons without HPoV infection were heterozygous for SDF1 and CCR2. The number of individuals bearing wt of all co-receptors in the group of persons not infected with HPoV was lower (P = 0.03) than that with polymorphism/s in one or two genes (SDF1 and CCR2) in the same group. The results suggest a probable role of co-receptors used by HIV to facilitate infection with HPoV.

    Shared attention is extremely common. In stadiums, public squares, and private living rooms, people attend to the world with others. Humans do so across all sensory modalities-sharing the sights, sounds, tastes, smells, and textures of everyday life with one another. The potential for attending with others has grown considerably with the emergence of mass media technologies, which allow for the sharing of attention in the absence of physical co-presence. In the last several years, studies have begun to outline the conditions under which attending together is consequential for human memory, motivation, judgment, emotion, and behavior. Here, I advance a psychological theory of shared attention, defining its properties as a mental state and outlining its cognitive, affective, and behavioral consequences. I review empirical findings that are uniquely predicted by shared-attention theory and discuss the possibility of integrating shared-attention, social-facilitation, and social-loafing perspectives. Finally, I reflect on what shared-attention theory implies for living in the digital world.

    To the best of our knowledge, the genetic foundations that guide human brain development have not changed fundamentally during the past 50,000 years. However, because of their cognitive potential, humans have changed the world tremendously in the past centuries. They have invented technical devices, institutions that regulate cooperation and competition, and symbol systems, such as script and mathematics, that serve as reasoning tools. The exceptional learning ability of humans allows newborns to adapt to the world they are born into; however, there are tremendous individual differences in learning ability among humans that become obvious in school at the latest. Cognitive psychology has developed models of memory and information processing that attempt to explain how humans learn (general perspective), while the variation among individuals (differential perspective) has been the focus of psychometric intelligence research. Although both lines of research have been proceeding independently, they increasingly converge, as both investigate the concepts of working memory and knowledge construction. This review begins with presenting state-of-the-art research on human information processing and its potential in academic learning. Then, a brief overview of the history of psychometric intelligence research is combined with presenting recent work on the role of intelligence in modern societies and on the nature-nurture debate. Finally, promising approaches to integrating the general and differential perspective will be discussed in the conclusion of this review.

  14. Human factors/ergonomics as a systems discipline? "The human use of human beings" revisited.

    Hollnagel, Erik

    2014-01-01

    Discussions of the possible future of Human factors/ergonomics (HFE) usually take the past for granted in the sense that the future of HFE is assumed to be more of the same. This paper argues that the nature of work in the early 2010s is so different from the nature of work when HFE was formulated 60-70 years ago that a critical reassessment of the basis for HFE is needed. If HFE should be a systems discipline, it should be a soft systems rather than a hard systems discipline. It is not enough for HFE to seek to improve performance and well-being through systems design, since any change to the work environment in principle alters the very basis for the change. Instead HFE should try to anticipate how the nature of work will change so that it can both foresee what work will be and propose what work should be.

    Full Text Available What does make the ground of the authentic works of music art crossing the centuries and what does move the human soul any time and anywhere? Which is the support of music art – generally speaking – beyond its aesthetic dimension? How could we explain and understand, in a better and in a more efficient way, the powerful influence of musical artistic creation upon the human well-being? These are merely part of the interrogations challenging our interest in finding and revealing the profound link between ethical values, music art and human health (in its integrality. The purpose of this essay is to emphasize the foundation of human equilibrium considering the offer of the harmony carried by music art, exploring the significance of a nucleus-concept of the Greek philosophers that has been acknowledged as kalokagatheia – the self-fulfilled cultivation of body and soul, as a micro-cosmos living within the macro-cosmos. In terms of a philosophical hermeneutics of art, we reach to disclose part of the salutogenic function of music art concerning the human well-being in nowadays.

  18. Revitalizing urban waterfronts: identifying indicators for human well-being

    Full Text Available Waterfront cities worldwide have begun the process of regenerating and developing their formerly industrial waterfronts into land uses that reflect a post-industrial economic vision of mixed urban uses supporting a diverse economy and wide range of infrastructure. These revitalization projects require distinct planning and management tactics to determine project-defined successes inclusive of economic, ecological, and human well-being perspectives. While empirically developed templates for economic and ecological measures exist, the multi-dimensionality and subjective nature of human well-being is more difficult to assess. Through an extensive review of indicator frameworks and expert interviews, our research proposes an organizational, yet adaptable, human well-being indicators framework for the management and development of urban waterfront revitalization projects. We analyze the framework through the lens of two waterfront projects in the Puget Sound region of the United States and identify several key factors necessary to developing project-specific human well-being indicator frameworks for urban waterfront revitalization projects. These factors include: initially specify goals and objectives of a given project, acknowledge contextual conditions including prospective land uses and projected users, identify the stage of development or management to use appropriate indicators for that stage, and develop and utilize data sources that are at a similar scale to the size of the project.

  1. Sharing Graphs

    CERN Document Server

    Sahasranand, K R

    2010-01-01

    Almost all known secret sharing schemes work on numbers. Such methods will have difficulty in sharing graphs since the number of graphs increases exponentially with the number of nodes. We propose a secret sharing scheme for graphs where we use graph intersection for reconstructing the secret which is hidden as a sub graph in the shares. Our method does not rely on heavy computational operations such as modular arithmetic or polynomial interpolation but makes use of very basic operations like assignment and checking for equality, and graph intersection can also be performed visually. In certain cases, the secret could be reconstructed using just pencil and paper by authorised parties but cannot be broken by an adversary even with unbounded computational power. The method achieves perfect secrecy for (2, n) scheme and requires far fewer operations compared to Shamir's algorithm. The proposed method could be used to share objects such as matrices, sets, plain text and even a heterogeneous collection of these. S...

  2. The egg-sharing model for human therapeutic cloning research: managing donor selection criteria, the proportion of shared oocytes allocated to research, and amount of financial subsidy given to the donor.

    Recent advances in human therapeutic cloning made by Hwang and colleagues have opened up new avenues of therapy for various human diseases. However, the major bottleneck of this new technology is the severe shortage of human donor oocytes. Egg-sharing in return for subsidized fertility treatment has been suggested as an ethically justifiable and practical solution to overcome the shortage of donor oocytes for therapeutic cloning. Because the utilization of shared oocytes in therapeutic cloning research does not result in any therapeutic benefit to a second party, this would necessitate a different management strategy compared to their use for the assisted conception of infertile women who are unable to produce any oocytes of their own. It is proposed that the pool of prospective egg-sharers in therapeutic cloning research be limited only to younger women (below 30 years of age) with indications for either male partner sub-fertility or tubal blockage. With regards to the proportion of the shared gametes being allocated to research, a threshold number of retrieved oocytes should be set that if not exceeded, would result in the patient being automatically removed from the egg-sharing scheme. Any excess supernumerary oocyte above this threshold number can be contributed to science, and allocation should be done in a randomized manner. Perhaps, a total of 10 retrieved oocytes from the patient may be considered a suitable threshold, since the chances of conception are unlikely to be impaired. With regards to the amount of subsidy being given to the patient, it is suggested that the proportion of financial subsidy should be equal to the proportion of the patient's oocytes being allocated to research. No doubt, the promise of future therapeutic benefit may be offered to the patient instead of financial subsidy. However, this is ethically controversial because therapeutic cloning has not yet been demonstrated to be a viable model of clinical therapy and any promises made to

    2014-02-01

    Researchers identify the importance of belonging to human well-being and provide evidence-based support for occupation as a medium for expressing and achieving a sense of belonging and connectedness. The purpose of this article is to highlight the imperative for occupational therapy theory and practice to address occupations concerned with belonging needs. Dominant occupational therapy models emphasise doing self-care, productive, and leisure occupations, thereby ignoring occupations undertaken to contribute to the well-being of others, occupations that foster connections to nature and ancestors, collaborative occupations, and those valued for their social context and potential to strengthen social roles. Belonging, connectedness, and interdependence are positively correlated with human well-being, are prioritized by the majority of the world's people, and inform the meanings attributed to and derived from the occupations of culturally diverse people. If occupational therapy is to address meaningful occupations, attention should be paid to occupations concerned with belonging, connecting, and contributing to others.

    Berylium (Be) is, together with As, Cd, Hg, Pb and Ti, one of the trace elements more toxic for human being (Vaessen) and Szteke, 2000; Yaman and Avci, 2006), but in spite of the exponential increment of its applications during the last decades, surprisingly there isn't hardly information about its presence and environmental distribution. The aim of this work is to evaluate the presence of Beryllium in urban soils in Alcala de Henares, (Madrid Spain).

    Light and dark are used pervasively to represent positive and negative concepts. Recent studies suggest that black and white stimuli are automatically associated with negativity and positivity. However, structural factors in experimental designs, such as the shared opposition in the valence (good vs. bad) and brightness (light vs. dark) dimensions might play an important role in the valence– brightness association. In 6 experiments, we show that while black ideographs are consistently judged ...

  6. Minority workers or minority human beings? A European dilemma

    Skutnabb-Kangas, Tove; Phillipson, Robert

    1996-07-01

    "European" identities may be politonymic, toponymic, ethnomyic or linguonymic (Bromley 1984). Each dimension may affect whether migrant minorities are treated as "European", and influence their schooling, integration and rights. Treatment and terminology vary in different states and periods of migration. However, the position for immigrated minorities is that they are still largely seen as workers rather than human beings with equal rights. Lack of success in schools is blamed on the migrants themselves rather than the educational system. This construction of migrants as being deficient is parallel to educational practice which falls within a UN definition of linguistic genocide, and contributes to mis-education. If current efforts in international bodies to codify educational linguistic human rights were to lead to greater support for minorities, this could assist in a redefinition of national identities and a reduction of racism and conflict.

    Trafficking in human beigns (THB) is recognized as a global public health issue as well as a violation of human rights. Trafficking has been identified to be associated with several health risks including psychological trauma, injuries from violence, and substance misuse. Public and media reports suggest that the morbidity and mortality associated with trafficking are substantial. The need of medico-legal healthcare for THB victims is being neglected. Forensic medical examination, as specific intervention, is a highly desirable element of ermegency health care provided for victims of tracking. Acting in such a way, the investigation should establish the facts related to the allegatation of trafficking, thereby assisting in identifying those responsible, but also contributing to the procedures designed to obtain redress for the victims. Local anti-trafficking policies and interventions, however, have not acknowledged these needs. Therefore, the agenda of anti-trafficking policies needs to be redrawn to include forensic medical assessment of victims for legal purposes.

    2012-01-01

    Lacking a coordinated effort in utilizing data and tracking program outcomes, one agency developed a Quality Management (QM) division to facilitate and manage more effective data use. To support this process, the agency sought to develop a collective, agency-wide understanding and investment in improving and measuring client outcomes. Similarly, the agency also focused efforts on creating a culture of transparency and accountability, with goals of improving service, increasing agency integrity, meeting regulatory compliance, and engaging in effective risk management. Operationalizing the QM initiative involved developing procedures, systems, and guidelines that would facilitate the generation of reliable and accurate data that could be used to inform program change and decision-making. This case study describes this agency's experience in successfully creating and implementing a QM initiative aimed at engaging in greater knowledge sharing.

    2010-12-01

    Full Text Available A mission to reduce the rate of loss of biodiversity as a contribution to poverty reduction was agreed as part of the Strategic Plan for the Convention on Biological Diversity, adopted by the Conference of the Parties in 2002. As 2010 draws to a close it is clear that this target will not be met. To continue and build on momentum generated by the 2010 target, the conservation community has been discussing a potential post-2010 framework that again includes explicit reference to the link between human wellbeing and conservation, and also considers the links with human wellbeing and sustainable development. Given this agreement, we reviewed several human wellbeing and sustainable development indicators compared to existing biodiversity status and trends indicators to determine if clear correlations can be found that could be used to track progress in a new framework. We undertook this review at both the global and continental levels. The indicators for protected area and forest cover showed significant positive correlation across all continents. We found a significant negative correlation between changes in protected area (PA cover and tonnage of greenhouse gas emissions released (GHGe between 1990 and 2005 for all the continents. At the global level we found no other correlation across the indicators reviewed. However, we found that correlations between the biodiversity and human wellbeing and sustainable development indicators varied across continents. As the only indicators for which global level correlations exist, we suggest that either protected area coverage or forest cover may be relevant biodiversity indicators for global analyses of biodiversity-human wellbeing or sustainable development relationships, and that the relationship between protected area cover and greenhouse gases could be one indicator for links between biodiversity and sustainable development. More research is needed to better understand factors involved in the

    Ayala, Francisco J

    2010-05-11

    In The Descent of Man, and Selection in Relation to Sex, published in 1871, Charles Darwin wrote: "I fully ... subscribe to the judgment of those writers who maintain that of all the differences between man and the lower animals the moral sense or conscience is by far the most important." I raise the question of whether morality is biologically or culturally determined. The question of whether the moral sense is biologically determined may refer either to the capacity for ethics (i.e., the proclivity to judge human actions as either right or wrong), or to the moral norms accepted by human beings for guiding their actions. I propose that the capacity for ethics is a necessary attribute of human nature, whereas moral codes are products of cultural evolution. Humans have a moral sense because their biological makeup determines the presence of three necessary conditions for ethical behavior: (i) the ability to anticipate the consequences of one's own actions; (ii) the ability to make value judgments; and (iii) the ability to choose between alternative courses of action. Ethical behavior came about in evolution not because it is adaptive in itself but as a necessary consequence of man's eminent intellectual abilities, which are an attribute directly promoted by natural selection. That is, morality evolved as an exaptation, not as an adaptation. Moral codes, however, are outcomes of cultural evolution, which accounts for the diversity of cultural norms among populations and for their evolution through time.

    The experimentation on human beings of one or several therapeutic molecules discovered in laboratory is necessary and important because it helps to find new treatments or new diagnostic methods. But, it presents serious ethical problems. In this article we are analysing the example of the HIV infection. We are succinctly describing the research methods in laboratory for therapeutic molecules, first the experimentation on animals and then on human being in clinical trials. We will then try to show, with several examples, how during these last 25 years of HIV infection, the research of new molecules has not always respected the ethical rules set out in Helsinki declaration, "Code de la santé publique" or "Guide de bonnes pratiques cliniques-ICH" etc. We are discussing here the way to avoid these irregularities.

    Functional food for prevention of chronic diseases is one of this century's key global challenges. Cancer is not only the first or second leading cause of death in China and other countries across the world, but also has diet as one of the most important modifiable risk factors. Major dietary factors now known to promote cancer development are polished grain foods and low intake of fresh vegetables, with general importance for an unhealthy lifestyle and obesity. The strategies of cancer prevention in human being are increased consumption of functional foods like whole grains (brown rice, barley, and buckwheat) and by-products, as well some vegetables (bitter melon, garlic, onions, broccoli, and cabbage) and mushrooms (boletes and Tricholoma matsutake). In addition some beverages (green tea and coffee) may be protective. Southwest China (especially Yunnan Province) is a geographical area where functional crop production is closely related to the origins of human evolution with implications for anticancer influence.

    Full Text Available In this article, the intersection of gender, trafficking for sexual exploitation, and use of digital communication technologies are analyzed based on data from the European Union (EU. Over the past two decades, an increase in trafficking in human beings in the EU has been accompanied by an increase in the development and availability of digital communication technologies. The first statistical analysis of trafficking in human beings (2008-2010 carried out by the European Commission found 23,632 victims of human trafficking in the reporting member states. Eighty percent of victims were women and girls; 20% were men and boys. The majority of the victims (62% were trafficked for sexual exploitation. Digital communication technologies are widely used for trafficking for sexual exploitation, and more rarely for trafficking for forced labor. This article concludes that the combination of gender, trafficking for sexual exploitation, and use of digital communication technologies has created a nexus of victimization for women and girls. Based on this analysis and other sources of information, the European region is the world’s leading region for trafficking for sexual exploitation.

    Full Text Available The current study explored how physical attractiveness affects food sharing by studying payment preferences for hypothetical romantic dinner dates (a hypothetical mating market. We analyzed payment preferences, self-rated attractiveness, and rated attractiveness for hypothetical dates in 416 participants. We hypothesized that (1 men would be more likely to prefer to pay than would women, (2 attractive individuals of both sexes would be less willing to pay, and (3 preferences to enter an exchange would be influenced by the attractiveness of prospective partners such that (3a men would prefer to pay for attractive women, and (3b women would prefer to be paid for by attractive men. All hypotheses were supported by our results. Individuals with higher self-rated attractiveness were more likely to prefer that their date would pay for the meal, and we found clear sex differences in how the attractiveness of potential dates affected payment preferences. Male participants preferred to pay for dates that had higher facial attractiveness, while female participants preferred that attractive men would pay. Individuals show condition dependent financial preferences consistent with the provisioning hypothesis in this mating market that are adaptive to evaluations of their own quality and that of prospective partners.

    2016-04-01

    In last ten years, a lot of researchers have begun to look into obtaining electricity from the movement between human and their backpack that occurs during walking. In this paper, an innovative, elastically-suspended backpack with mechanical motion rectifier (MMR) based energy harvester is developed to generate electricity with high efficiency and reliability. Up to 28 Watts peak electrical power can be produced by the MMR based backpack energy harvester. A dynamic model for the system is presented along with experimental results. Three dual mass models for different distinct harvesters: pure viscous, non MMR, and MMR, are proposed, and a comparison in the output power and human comfort between the three models is discussed.

    1978-01-01

    A hierarchy of human activities is derived by analyzing automobile driving in general terms. A structural description leads to a block diagram and a time-sharing computer analogy. The range of applicability of existing mathematical models is considered with respect to the hierarchy of human activities in actual complex tasks. Other mathematical tools so far not often applied to man machine systems are also discussed. The mathematical descriptions at least briefly considered here include utility, estimation, control, queueing, and fuzzy set theory as well as artificial intelligence techniques. Some thoughts are given as to how these methods might be integrated and how further work might be pursued.

    Directory of Open Access Journals (Sweden)

    Elisa Morgera

    2015-12-01

    Full Text Available As the debate about the need to clarify the content of the human right to science intensifies, this article assesses opportunities for opening a scholarly and policy dialogue on fair and equitable benefit-sharing between international human rights and biodiversity lawyers. To that end, the article contrasts the emerging conceptualizations of the right to science in the context of international cultural rights and of fair and equitable benefit-sharing under international biodiversity law. It then critically assesses the potential for cross-fertilization with specific regard to: the sharing of scientific information and promotion of scientific cooperation, the transfer of technology, and the protection and valorization of traditional knowledge of indigenous peoples and local communities. While acknowledging that both the right to science and fair and equitable benefit-sharing are far from being fully understood or operationalized, the article argues that developments in international biodiversity law concerning the latter may provide insights into how a vague and optimistic concept can (and when it cannot lead to tangible outcomes, rather than remaining merely rhetorical.

    Directory of Open Access Journals (Sweden)

    Markus ePaulus

    2014-06-01

    Full Text Available Recent studies have provided evidence that young children already engage in sharing behavior. The underlying social‐cognitive mechanisms, however, are still under debate. In particular, it is unclear whether or not young children’s sharing is motivated by an appreciation of others’ wealth. Manipulating the material needs of recipients in a sharing task (Experiment 1 and a resource allocation task (Experiment 2, we show that 5‐ but not 3‐year‐old children share more with poor than wealthy individuals. The 3-year-old children even showed a tendency to behave less selfishly towards the rich, yet not the poor recipient. This suggests that very early instances of sharing behavior are not motivated by a consideration of others’ material needs. Moreover, the results show that 5-year-old children were rather inclined to give more to the poor individual than distributing the resources equally, demonstrating that their wish to support the poor overruled the otherwise very prominent inclination to share resources equally. This indicates that charity has strong developmental roots in preschool children.

    2017-05-01

    Full Text Available After last year’s analysis regarding the European Union’s commitment to fight against the human beings trafficking, we have considered to further explore the human beings trafficking approach in the European Court of Human Rights case-law, the most developped regional jurisdiction on human rights. Surprisingly, the European Convention for the Protection of Human Rights and Fundamental Freedoms does not make an express reference to the human beings trafficking. However, we have to bear in mind that the Convention is a living instrument, its interpretation being made in the light of the present-day conditions. Thus, taking into consideration the global threat of this phenomenon, it is more obvious than ever that the Convention could not neglect this issue.

  1. Chimpanzees share forbidden fruit.

    Directory of Open Access Journals (Sweden)

    Kimberley J Hockings

    Full Text Available The sharing of wild plant foods is infrequent in chimpanzees, but in chimpanzee communities that engage in hunting, meat is frequently used as a 'social tool' for nurturing alliances and social bonds. Here we report the only recorded example of regular sharing of plant foods by unrelated, non-provisioned wild chimpanzees, and the contexts in which these sharing behaviours occur. From direct observations, adult chimpanzees at Bossou (Republic of Guinea, West Africa very rarely transferred wild plant foods. In contrast, they shared cultivated plant foods much more frequently (58 out of 59 food sharing events. Sharing primarily consists of adult males allowing reproductively cycling females to take food that they possess. We propose that hypotheses focussing on 'food-for-sex and -grooming' and 'showing-off' strategies plausibly account for observed sharing behaviours. A changing human-dominated landscape presents chimpanzees with fresh challenges, and our observations suggest that crop-raiding provides adult male chimpanzees at Bossou with highly desirable food commodities that may be traded for other currencies.

    Many testis-specific genes from the sex chromosomes are subject to rapid evolution, which can make it difficult to identify murine genes in the human genome. The murine CYPT gene family includes 15 members, but orthologs were undetectable in the human genome. However, using refined homology search...... with the murine SPANX gene and the CYPT family may share a common ancestor. Finally, we present evidence that VCX/Y and SPANX may be paralogs with a similar protein structure consisting of C terminal acidic repeats of variable lengths....

    2015-04-01

    The purpose of this study was to investigate whether S. pseudintermedius is misdiagnosed as S. aureus by clinical laboratories when isolated from humans with dog bite wounds. In addition, we attempted to determine whether S. pseudintermedius isolates related to dog bite wounds share phenotypic and genotypic traits. S. pseudintermedius was identified by PCR targeting the nuc gene. Isolates were tested for antibiotic susceptibility using VetMIC GP-mo microdilution panels. The occurrence of genes encoding leukocidins, exfoliatins, pyrogenic toxin superantigens and enterotoxins was determined by PCR. The relatedness of S. pseudintermedius isolates was investigated using Multi Locus Sequence Typing (MLST). Out of 101 isolates defined as S. aureus by human clinical microbiology laboratories, 13 isolates were re-identified as S. pseudintermedius and one isolate was confirmed to carry the mecA gene, i.e. methicillin-resistant (MRSP). The MRSP isolate was also defined as multi-resistant. Two methicillin-susceptible S. pseudintermedius isolates were also multi-resistant and five were susceptible to all antibiotics tested. With the exception of three S. pseudintermedius isolates belonging to multi locus sequence type (MLST) 158, all the isolates belonged to unique STs. All isolates contained lukS/F-I, siet and se-int, and expA were identified in two isolates and expB and sec canine-sel in one isolate respectively. S. pseudintermedius is frequently misdiagnosed as S. aureus from humans with dog bite wounds showing that it can act as an opportunistic pathogen in humans. No common phenotypic and genotypic traits shared by the S. pseudintermedius isolates could be identified.

    Objective Diagnose ethical conduct in research involving human beings in Brazil and the last 10 years of activity by the Human Research Ethics Committee of the Health Department - Federal District - CEP/SES/DF. Methods This work was based on a documentary research, descriptive and retrospective. It examined the database containing records of cases brought before the CEP/SES/DF, corresponding the period of June 1997 to December 2007. Results were generated in Excel program, version 2007. Results CEP/SES/DF has presented increasing number of research projects submitted to appreciation (n = 1129), composing: 90.4% approved 1.7% disapproved, 7.4% removed/filed and 0.5% excluded. Of these projects, 83% belonged to Group III, 18% multi-centered projects and 10% protocols with foreign participation. Time for approval has decreased over the years (30 to 60 days). Frequent pendencies: End of Free and Informed Consent (30%), Cover Sheet (25%), Methodology (20%), Curriculum vitae (12%), Budget (9%), and Others (4%). Conclusion The assessment of the CEP/SES/DF activities, during a ten-year period has shown its commitment to the legitimacy of research ethics review and scientific production SES/DF. There were some weaknesses such as difficulty in monitoring the accompaniment of the research; interruption of works due to adverse drug reaction; gaps or errors in the protocol submitted by the researcher. These situations are the achieving targets for the elaboration of specific criteria. PMID:20981277

    Developing countries have experienced a dramatic increase in the number of clinical studies in the last decades. The aim of this study was to describe 1) the number of clinical trials submitted to the Brazilian Health Surveillance Agency (Agência Nacional de Vigilância Sanitária, Anvisa) from 2007 to 2012 and the number of human-subject research projects approved by research ethics committees (RECs) and the National Research Ethics Committee (Comissão Nacional de Ética em Pesquisa, CONEP) in Brazil from 2007 to 2011 and 2) the diseases most frequently studied in Brazilian states in clinical trials approved in the country from 2009 to 2012, based on information from an Anvisa databank. Two databases were used: 1) the National Information System on Research Ethics Involving Human Beings (Sistema Nacional de Informação Sobre Ética em Pesquisa envolvendo Seres Humanos, SISNEP) and 2) Anvisa's Clinical Research Control System (Sistema de Controle de Pesquisa Clínica, SCPC). Data from the SCPC indicated an increase of 32.7% in the number of clinical trials submitted to Anvisa, and data from the SISNEP showed an increase of 69.9% in those approved by RECs and CONEP (from 18 160 in 2007 to 30 860 in 2011). Type 2 diabetes (26.0%) and breast cancer (20.5%)-related to the main causes of mortality in Brazil-were the two most frequently studied diseases. The so-called “neglected diseases,” such as dengue fever, were among the least studied diseases in approved clinical trials, despite their significant impact on social, economic, and health indicators in Brazil. Overall, the data indicated 1) a clear trend toward more research involving human beings in Brazil, 2) good correspondence between diseases most studied in clinical trials approved by Anvisa and the main causes of death in Brazil, and 3) a low level of attention to neglected diseases, an issue that should be considered in setting future research priorities, given their socioeconomic and health effects.

    Full Text Available In this research, we use a combination of ethnographic observation and GIS analysis to explore the use of space by humans and gibbons (Hylobates moloch to determine areas of potential space competition in the sacred forest and nature reserve Cagar Alam Leuweung Sancang in West Java, Indonesia. More specifically, we test whether gibbons respond to the presence of humans in a manner consistent with predator-avoidance and predicted that the gibbon study subjects would avoid areas visited by humans (Risk-Disturbance Hypothesis. Data were collected August 2010-June 2011. We collected GPS locations and behavioral data on both the humans (6,652 hours and the gibbons (1,253 hours in the forest using 10 minute instantaneous sampling. Results indicate that humans preferentially assemble at the most sacred spot in the forest (Cikajayaan waterfall. Two gibbon groups' home ranges encompassed most of the sacred areas. Group B avoided areas of high human use, as high human use areas and high gibbon use areas did not overlap. Group C, though, continued to use areas that were heavily visited by humans. We thus found partial support for the Risk-Disturbance Hypothesis, although the variation in gibbon response to human disturbance indicates behavioral flexibility. We suggest that understanding the effects of shared space on wildlife is necessary for informing conservation policy in human-visited forests.

    Past research has demonstrated that equality-based respect is an important antecedent of positive social interaction and group-serving behavior. In the present research we tested whether intragroup equality-based respect affects perceptions of being treated as a human as well as self-dehumanization. In Experiment 1, we found that high respect received from fellow work group members heightens group members' sense of being treated as a human being, while low respect diminishes it. In Experiment 2, we secured evidence that (dis)respect also affected recipients' self-views in terms of self-dehumanization. More specifically, if respect was withheld by other ingroup members, fewer human nature and human uniqueness traits, as well as secondary positive emotions, were attributed to the self. This increase in self-infrahumanization was further related to higher endorsement of unethical behavior. We discuss the importance of equality-based respect for (de-)humanization processes in social groups.

    Full Text Available Abstract Background Keloids are benign skin tumors that are the effect of a dysregulated wound-healing process in genetically predisposed patients. They are inherited with an autosomal dominant mode with incomplete clinical penetrance and variable expression. Keloids are characterized by formation of excess scar tissue beyond the boundaries of the wound. The exact etiology is still unknown and there is currently no appropriate treatment for keloid disease. Methods We analyzed sample tissues were obtained from 20 patients with keloid skin lesions and normal skin was obtained from 20 healthy donors. The telomeres were measured by Terminal Restriction Fragment (TRF analysis and Real-Time PCR assay. Quantitative Real-Time RT-PCR analysis of hTERT gene expression was performed and intracellular ROS generation was measured. Results In this study, we determined whether telomeric shortening and the expression of human telomerase reverse transcriptase (hTERT occurs in keloid patients. Using Terminal Restriction Fragment (TRF analysis and Real-Time PCR assay, we detected a significant telomere shortening of 30% in keloid specimens compared to normal skin. Using quantitative Real-Time RT-PCR, telomerase activity was found absent in the keloid tissues. Moreover, an increase in ROS generation was detected in fibroblasts cell cultures from keloid specimens as more time elapsed compared to fibroblasts from normal skin. Conclusion Telomere shortening has been reported in several metabolic and cardiovascular diseases. We found that telomere shortening can also be associated with human keloids. Chronic oxidative stress plays a major role in the pathophysiology of several chronic inflammatory diseases. Here we found increased ROS generation in fibroblasts from keloid fibroblasts cell cultures when compared to normal skin fibroblasts. Hence we conclude that oxidative stress might be an important modulator of telomere loss in keloid because of the absence of active

    The concept of knowledge management has, indeed, become a buzzword that every single organization is expected to practice and live by. Knowledge management is about managing the organization's knowledge for the common good of the organization -but practicing knowledge management is not as simple...... as that. This article focuses on knowledge sharing as the process seeking to reduce the resources spent on reinventing the wheel.The article introduces the concept of time sensitiveness; i.e. that knowledge is either urgently needed, or not that urgently needed. Furthermore, knowledge sharing...... is considered as either a push or pull system. Four strategies for sharing knowledge - help, post-it, manuals and meeting, and advice are introduced. Each strategy requires different channels for sharing knowledge. An empirical analysis in a production facility highlights how the strategies can be practiced....

    Pheochromocytomas are rare neoplasias of neural crest origin arising from chromaffin cells of the adrenal medulla and sympathetic ganglia (extra-adrenal pheochromocytoma). Pheochromocytoma that develop in rats homozygous for a loss-of-function mutation in p27Kip1 (MENX syndrome) show a clear progression from hyperplasia to tumor, offering the possibility to gain insight into tumor pathobiology. We compared the gene-expression signatures of both adrenomedullary hyperplasia and pheochromocytoma with normal rat adrenal medulla. Hyperplasia and tumor show very similar transcriptome profiles, indicating early determination of the tumorigenic signature. Overrepresentation of developmentally regulated neural genes was a feature of the rat lesions. Quantitative RT-PCR validated the up-regulation of 11 genes, including some involved in neural development: Cdkn2a, Cdkn2c, Neurod1, Gal, Bmp7, and Phox2a. Overexpression of these genes precedes histological changes in affected adrenal glands. Their presence at early stages of tumorigenesis indicates they are not acquired during progression and may be a result of the lack of functional p27Kip1. Adrenal and extra-adrenal pheochromocytoma development clearly follows diverged molecular pathways in MENX rats. To correlate these findings to human pheochromocytoma, we studied nine genes overexpressed in the rat lesions in 46 sporadic and familial human pheochromocytomas. The expression of GAL, DGKH, BMP7, PHOX2A, L1CAM, TCTE1, EBF3, SOX4, and HASH1 was up-regulated, although with different frequencies. Immunohistochemical staining detected high L1CAM expression selectively in 27 human pheochromocytomas but not in 140 nonchromaffin neuroendocrine tumors. These studies reveal clues to the molecular pathways involved in rat and human pheochromocytoma and identify previously unexplored biomarkers for clinical use. PMID:20937862

    Full Text Available The Tangguh Liquefied Natural Gas (LNG Project is a planned natural gas development project located in the remote area of Berau-Bintuni Bay in Papua Province, Indonesia. British Petroleum (BP Tangguh project aims tobe the pioneer in producing natural gas. It can be concluded that BP contributes an innovative approach, bearing in mind to sustainable development, cultural preservation and biodiversity conservation. Therefore, in each of its corporate actions, BP always integrates the value of community, partnership, consultation and corporate responsibility. It is mentioned that through experience and observation, BP as an extractive company, haveestimated the costs of not finding a better mechanism to adjust to social challenges can be higher than the costs of the uncertainties inherent in the trial of new ideas. However, according to international Non-GovernmentalOrganization (NGO, Down to Earth, BP has conducted a series of human rights violations by exploiting natural resources in Papua and restricting Papuans in enjoying their fundamental human rights. If only the BP keeps this Tangguh project in line with its aim to accommodate concerns from the affected surroundings, thus, will surely bring positive changes in BP’s corporate shared value.

    Women in the U.S. face significant structural constraints in attempting to breastfeed as recommended in the first six months of their child's life. Internet-facilitated human milk sharing is an emergent response to breastfeeding challenges. Little is known about the demographic characteristics of milk sharing donors and recipients and the ways structural factors circumscribe the biocultural context of lactation in milk sharing practices. Data regarding demographic characteristics, reproductive history, lactation history, and levels of social support and health care provider support for breastfeeding were collected via an online survey September 2013-March 2014. Statistical tests were executed to ascertain whether significant differences exist between donors and recipients. A total of 867 respondents (661 donors, 206 recipients) met the eligibility criteria for the study. Respondents were U.S. residents and primarily White, middle-class, well educated, and employed women. Both donors and recipients reported higher than the national average for household income, maternal educational attainment, breastfeeding exclusivity 0-6 months, and breastfeeding duration. Differences in lactation sufficiency and breastfeeding outcomes between donors and recipients were associated with both structural and biocultural factors. Donors reported significantly higher income, education, and support for breastfeeding from spouse/partner, other family, employers, and pediatricians. Donors also reported significantly higher rates of full term birth for child of most recent lactation. This study provides a foundation for understanding how milk sharing reflects a broader political economy of breastfeeding in the U.S.

  15. Human endothelial senescence can be induced by TNF-α

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    TNF-α is one of the most important proinfiammatory cytokines in mediating multiple physio-pathological functions during immunological responses. Vascular endothelial cells, when stimulated by TNF-α2 can increase the expression of multiple cytokines and cellular adhesion molecules and, in turn, actively promote the inflammatory responses by recruiting and activating of leukocytes to the inflammatory site. In addition to endothelial death induced by TNF-α2 we found for the first time that TNF-α can also induce the human endothelial cells senescence. The induced senescent endothelial cells will display SA-β-Gal staining and they were arrested in G0-G1 phase. We found that Aψm would always be up-regulated in response to TNF-α stimulation at early time but when the cells become senescent, A ψmshows a tendency to decrease. It may reflect the sthenic function of mitochondria at early time in response to TNF-αstimulation and decay when the endothelial cells were induced senescent. ROS fluctuates at early time and also decreases when the endothelial cells become senescent. Our results show that the change of mitochondrial function may be related to the senescent process.``

    We developed high resolution L(Y)SO detectors for human and animal PET applications using Photomulti- plier-quadrant-sharing (PQS) technology. The crystal sizes were 1.27 times 1.27 times 10 mm3 for the animal PQS-blocks and 3.25 times 3.25 times 20 mm3 for human ones. Polymer mirror film patterns (PMR) were placed between crystals as reflector. The blocks were assembled together using optical grease and wrapped by Teflon tape. The blocks were coupled to regular round PMTs of 19/51 mm in PQS configuration. List-mode data of Ga-68 source (511 keV) were acquired with our high yield pileup-event recovery (HYPER) electronics and data acquisition software. The high voltage bias was 1100 V. Crystal decoding maps and individual crystal energy resolutions were extracted from the data. To investigate the potential imaging resolution of the PET cameras with these blocks, we used GATE (Geant4 Application for Tomographic Emission) simulation package. GATE is a GEANT4 based software toolkit for realistic simulation of PET and SPECT systems. The packing fractions of these blocks were found to be 95.6% and 98.2%. From the decoding maps, all 196 and 225 crystals were clearly identified. The average energy resolutions were 14.1% and 15.6%. For small animal PET systems, the detector ring diameter was 16.5 cm with an axial field of view (AFOV) of 11.8 cm. The simulation data suggests that a reconstructed radial (tangential) spatial resolution of 1.24 (1.25) mm near the center is potentially achievable. For the whole-body human PET systems, the detector ring diameter was 86 cm. The simulation data suggests that a reconstructed radial (tangential) spatial resolution of 3.09(3.38) mm near the center is potentially achievable. From this study we can conclude that the PQS design could achieve high spatial resolutions and excellent energy resolutions on human and animal PET systems with substantially lower production costs and inexpensive readout devices.

    Full Text Available The purpose of this study was to demonstrate the impact of certain lifestyles in our daily lives, and to reference some of them, among which are a sedentary lifestyle, diet, physical activity, social and family support, and the impact they have on people’ quality of life. It is clear that as a human beings, the developments in everyday life are addressed by duties and rights that affect our way of living, hence all individuals should enjoy the right to a better quality of life; to achieve this, it is necessary to maintain healthy lifestyle habits that create mechanisms to protect people against the development of chronic degenerative diseases. Historically it has been shown that people who have unhealthy life habits develop over time no only hypokinetic diseases, but also neurological ones such as Alzheimer's and Parkinson's. Under this scenario this paper is intended to present clear and concise information about what lifestyles represent to people and their importance as a right for everyone who decides to adapt them to their daily lives.

    A social experiment in Denmark is described in which 25 families combine private ownership (each family owns its own home) and collectivism (each family owns 1/25 of the grounds, large common house and other facilities). The superinsulated individual homes are small (< 1000 ft/sup 2/) but the common house (7800 ft/sup 2/) provides dining and meeting facilities for all 25 families as well as a central heating plant. Heat may be supplied from solar, wind and/or oil-fired boiler. Adequate hot water storage is provided using solar collectors and a 55 kW Vesta wind generator (surplus power is sold). All south facing roof surfaces are fitted with solar collectors (4455 ft/sup 2/ total). A total of 70% of the energy used is produced on site (solar and wind). The manner of living and sharing (child care, automobiles, cooking, etc.) is described as well as typical floor plans for the units. Other collective housing in Denmark is described and it is postulated that overdrevet may serve as a model. (MJJ)

  20. Dogs and humans share a common susceptibility gene SRBD1 for glaucoma risk.

    Directory of Open Access Journals (Sweden)

    Nobuyuki Kanemaki

    Full Text Available Glaucoma is a degenerative optic neuropathy that is associated with elevated intraocular pressure. Primary open angle glaucoma is the most common type of glaucoma in canines, and its highest incidence among dog breeds has been reported in Shiba-Inus, followed by Shih-Tzus. These breeds are known to have an abnormal iridocorneal angle and dysplastic prectinate ligament. However, the hereditary and genetic backgrounds of these dogs have not yet been clarified. In this study, we investigated the association between polymorphisms of the glaucoma candidate genes, SRBD1, ELOVL5, and ADAMTS10, and glaucoma in Shiba-Inus and Shih-Tzus. We analyzed 11 polymorphisms in these three genes using direct DNA sequencing. Three SRBD1 SNPs, rs8655283, rs22018514 and rs22018513 were significantly associated with glaucoma in Shiba-Inus, while rs22018513, a synonymous SNP in exon 4, showed the strongest association (P = 0.00039, OR = 3.03. Conditional analysis revealed that rs22018513 could account for most of the association of these SNPs with glaucoma in Shiba-Inus. In Shih-Tzus, only rs9172407 in the SRBD1 intron 1 was significantly associated with glaucoma (P = 0.0014, OR = 5.25. There were no significant associations between the ELOVL5 or ADAMTS10 polymorphisms and glaucoma in Shiba-Inus and Shih-Tzus. The results showed that SRBD1 polymorphisms play an important role in glaucoma pathology in both Shiba-Inus and Shih-Tzus. SRBD1 polymorphisms have also been associated with normal- and high-tension glaucomas in humans. Therefore, SRBD1 may be a common susceptibility gene for glaucoma in humans and dogs. We anticipate that the nucleotide sequencing data from this study can be used in genetic testing to determine for the first time, the genetic status and susceptibility of glaucoma in dogs, with high precision. Moreover, canine glaucoma resulting from SRBD1 polymorphisms could be a useful animal model to study human glaucoma.

    Full Text Available Human monocytic ehrlichiosis is a tick-borne infectious disease transmitted by several tick species, especially Amblyomma spp caused by Ehrlichia chaffeensis. E. chaffeensis is an obligatory intracellular, tick-transmitted bacterium that is maintained in nature in a cycle involving at least one and perhaps several vertebrate reservoir hosts. Two additional Ehrlichia spp, Anaplasma (formerly Ehrlichia phagocytophila (the agent of human granulocytic ehrlichiosis [HGE] and E. ewingii (a cause of granulocytic ehrlichiosis in dogs act as human pathogens. Human E. chaffeensis infections have generally been reported in North America, Asia and Europe, but recently human cases have been reported in Brazil only. Human monocytic ehrlichiosis is diagnosed by demonstration of a four-fold or greater change in antibody titer to E. chaffeensis antigen by IFA in paired serum samples, or a positive PCR assay and confirmation of E. chaffeensis DNA, or identification of morulae in leukocytes and a positive IFA titer to E. chaffeensis antigen, or immunostaining of E. chaffeensis antigen in a biopsy or autopsy sample, or culture of E. chaffeensis from a clinical specimen.

  4. Can a Human-Induced Climate Disaster be Avoided?

    Emissions of greenhouse gases (GHG) are one of the greatest threats to our future prosperity. World emissions are currently around 50 billion tonnes of carbon dioxide-equivalent per annum and are growing rapidly. Atmospheric concentrations of GHG emissions in the atmosphere have increased, to over 400ppm of CO2e today, even after taking the offsetting radiative effects of aerosols into account, and are increasing at a rate of around 2.5ppm per year. The world's current lack of "adequate" commitments to reduce emissions are consistent with at least a 3oC rise (50-50 chance) in temperature: a temperature not seen on the planet for around 3 million years, with serious risks of 5oC rise: a temperature not seen on the planet for around 30 million years. So what are the implications of a 3-5oC rise in temperature, with associated changes in, rising sea levels, retreating mountain glaciers, melting of the Greenland ice cap, shrinking Arctic Sea ice, especially in summer, increasing frequency of extreme weather events, such as heat waves, floods, and droughts, and intensification of cyclonic events, such as hurricanes in the Atlantic. Even a 2oC increase in mean surface temperatures will adversely affect freshwater, food and fiber, natural ecosystems, coastal systems and low-lying areas, human health and social systems, especially in developing countries. The impacts of 3-5oC will be extensive, predominantly negative, undermine development and poverty alleviation goals and cut across most sectors. To address human-induced climate change requires a transition to a low carbon economy, which will require rapid technological evolution in the efficiency of energy use, environmentally sound low-carbon renewable energy sources and carbon capture and storage. The longer we wait to transition to a low carbon economy the more we are locked into a high carbon energy system with consequent environmental damage to ecological and socio-economic systems. Unfortunately the political will

  6. Psychological aspects of human cloning and genetic manipulation: the identity and uniqueness of human beings.

    Morales, N M

    2009-01-01

    Human cloning has become one of the most controversial debates about reproduction in Western civilization. Human cloning represents asexual reproduction, but the critics of human cloning argue that the result of cloning is not a new individual who is genetically unique. There is also awareness in the scientific community, including the medical community, that human cloning and the creation of clones are inevitable. Psychology and other social sciences, together with the natural sciences, will need to find ways to help the healthcare system, to be prepared to face the new challenges introduced by the techniques of human cloning. One of those challenges is to help the healthcare system to find specific standards of behaviour that could be used to help potential parents to interact properly with cloned babies or children created through genetic manipulation. In this paper, the concepts of personality, identity and uniqueness are discussed in relationship to the contribution of twin studies in these areas. The author argues that an individual created by human cloning techniques or any other type of genetic manipulation will not show the donor's characteristics to the extent of compromising uniqueness. Therefore, claims to such an effect are needlessly alarmist.

    Care-givers not only work as a team, but increasingly they also participate in networks. This development represents an ethical challenge to the exchange of information and to confidentiality. To revise and update earlier advice formulated by the Ethics Committee for Mental Health Care of the Brothers of Charity in Flanders, in particular concerning the question of whether shared confidentiality can be extended from a team to a network. The Ethics Committee applied an appropriate method which combined ethical discussion and literature research. The earlier advice is no longer adequate because of certain practical and theoretical grounds. The Ethics Committee chooses to take a positive view of the developing cooperation between care-givers and networks. Consequently, the committee proposes shared confidentiality, but links this to five conditions: (1) the care-givers should participate in a clearly defined and identifiable team or network, (2) they should have a caring task in common, (3) they should be pledged to confidentiality, (4) they should consult with the patient and obtain his/her informed consent, (5) they should apply 'the filter of relevance'. Care-givers can exchange information with members of a team or network, but this should be done on the basis of conditional shared confidentiality.

    Eosinophils are leukocytes that are released into the peripheral blood in a phenotypically mature state and are capable of being recruited into tissues in response to appropriate stimuli. Eosinophils, traditionally considered cytotoxic effector cells, are leukocytes recruited into the airways of asthma patients where they are believed to contribute to the development of many features of the disease. This perception, however, has been challenged by recent findings suggesting that eosinophils have also immunomodulatory functions and may be involved in tissue homeostasis and wound healing. Here we describe a transcriptome-based approach–in a limited number of patients and controls—to investigate the activation state of circulating human eosinophils isolated by flow cytometry. We provide an overview of the global expression pattern in eosinophils in various relevant conditions, e.g., eosinophilic asthma, hypereosinophilic dermatological diseases, parasitosis and pulmonary aspergillosis. Compared to healthy subjects, circulating eosinophils isolated from asthma patients differed in their gene expression profile which is marked by downregulation of transcripts involved in antigen presentation, pathogen recognition and mucosal innate immunity, whereas up-regulated genes were involved in response to non-specific stimulation, wounding and maintenance of homeostasis. Eosinophils from other hypereosinophilic disorders displayed a very similar transcriptional profile. Taken together, these observations seem to indicate that eosinophils exhibit non-specific immunomodulatory functions important for tissue repair and homeostasis and suggest new roles for these cells in asthma immunobiology.

  11. Elasticity in ecosystem services: exploring the variable relationship between ecosystems and human well-being

    Full Text Available Although ecosystem services are increasingly recognized as benefits people obtain from nature, we still have a poor understanding of how they actually enhance multidimensional human well-being, and how well-being is affected by ecosystem change. We develop a concept of "ecosystem service elasticity" (ES elasticity that describes the sensitivity of human well-being to changes in ecosystems. ES Elasticity is a result of complex social and ecological dynamics and is context dependent, individually variable, and likely to demonstrate nonlinear dynamics such as thresholds and hysteresis. We present a conceptual framework that unpacks the chain of causality from ecosystem stocks through flows, goods, value, and shares to contribute to the well-being of different people. This framework builds on previous conceptualizations, but places multidimensional well-being of different people as the final element. This ultimately disaggregated approach emphasizes how different people access benefits and how benefits match their needs or aspirations. Applying this framework to case studies of individual coastal ecosystem services in East Africa illustrates a wide range of social and ecological factors that can affect ES elasticity. For example, food web and habitat dynamics affect the sensitivity of different fisheries ecosystem services to ecological change. Meanwhile high cultural significance, or lack of alternatives enhance ES elasticity, while social mechanisms that prevent access can reduce elasticity. Mapping out how chains are interlinked illustrates how different types of value and the well-being of different people are linked to each other and to common ecological stocks. We suggest that examining chains for individual ecosystem services can suggest potential interventions aimed at poverty alleviation and sustainable ecosystems while mapping out of interlinkages between chains can help to identify possible ecosystem service trade-offs and winners and

    2012-05-01

    Full Text Available Heparan sulphate (HS and the related polysaccharide, heparin, exhibit conformational and charge arrangement properties, which provide a degree of redundancy allowing several seemingly distinct sequences to exhibit the same activity. This can also be mimicked by other sulphated polysaccharides, both in overall effect and in the details of interactions and structural consequences of interactions with proteins. Together, these provide a source of active compounds suitable for further development as potential drugs. These polysaccharides also possess considerable size, which bestows upon them an additional useful property: the capability of disrupting processes comprising many individual interactions, such as those characterising the attachment of microbial pathogens to host cells. The range of involvement of HS in microbial attachment is reviewed and examples, which include viral, bacterial and parasitic infections and which, in many cases, are now being investigated as potential targets for intervention, are identified.

    Full Text Available Sounds are the creatures of God which are found in nature in diverse forms. In addition to sounds naturally exist in the environment there are artificial sounds that is hand-maid and we experience them in our daily life. Industrialization has had detrimental effect on manufacturing such sounds in the environment which in turn can affect our mental and physical state. The current article is taking sound from a religious point of view into account. We want to discuss the role of sounds in perceiving the meanings of related concepts and also will have an overall look on the devastating effects of noise and irritating sounds on human life and the human mental and physical health.

  14. Do perfume additives termed human pheromones warrant being termed pheromones?

    Science.gov (United States)

    Winman, Anders

    2004-09-30

    Two studies of the effects of perfume additives, termed human pheromones by the authors, have conveyed the message that these substances can promote an increase in human sociosexual behaviour [Physiol. Behav. 75 (2003) R1; Arch. Sex. Behav. 27 (1998) R2]. The present paper presents an extended analysis of this data. It is shown that in neither study is there a statistically significant increase in any of the sociosexual behaviours for the experimental groups. In the control groups of both studies, there are, however, moderate but statistically significant decreases in the corresponding behaviour. Most notably, there is no support in data for the claim that the substances increase the attractiveness of the wearers of the substances to the other sex. It is concluded that more research using matched homogenous groups of participants is needed.

    It is imperative to unveil the full range of differentiated cell types into which human pluripotent stem cells (hPSCs) can develop. The need is twofold: it will delimit the therapeutic utility of these stem cells and is necessary to place their position accurately in the developmental hierarchy of lineage potential. Accumulated evidence suggested that hPSC could develop in vitro into an extraembryonic lineage (trophoblast (TB)) that is typically inaccessible to pluripotent embryonic cells during embryogenesis. However, whether these differentiated cells are truly authentic TB has been challenged. In this debate, we present a case for and a case against TB differentiation from hPSCs. By analogy to other differentiation systems, our debate is broadly applicable, as it articulates higher and more challenging standards for judging whether a given cell type has been genuinely produced from hPSC differentiation.

    Human pluripotent stem cells (PSCs) have the capacity to revolutionize medicine by allowing the generation of functional cell types such as neurons for cell replacement therapy. However, the more immediate impact of PSCs on treatment of Alzheimer's disease (AD) will be through improved human AD model systems for mechanistic studies and therapeutic screening. This review will first briefly discuss different types of PSCs and genome-editing techniques that can be used to modify PSCs for disease modeling or for personalized medicine. This will be followed by a more in depth analysis of current AD iPSC models and a discussion of the need for more complex multicellular models, including cell types such as microglia. It will finish with a discussion on current clinical trials using PSC-derived cells and the long-term potential of such strategies for treating AD. Copyright © 2015 Elsevier Ltd.

    Full Text Available Abstract Background The first week of human pre-embryo development is characterized by the induction of totipotency and then pluripotency. The understanding of this delicate process will have far reaching implication for in vitro fertilization and regenerative medicine. Human mature MII oocytes and embryonic stem (ES cells are both able to achieve the feat of cell reprogramming towards pluripotency, either by somatic cell nuclear transfer or by cell fusion, respectively. Comparison of the transcriptome of these two cell types may highlight genes that are involved in pluripotency initiation. Results Based on a microarray compendium of 205 samples, we compared the gene expression profile of mature MII oocytes and human ES cells (hESC to that of somatic tissues. We identified a common oocyte/hESC gene expression profile, which included a strong cell cycle signature, genes associated with pluripotency such as LIN28 and TDGF1, a large chromatin remodelling network (TOP2A, DNMT3B, JARID2, SMARCA5, CBX1, CBX5, 18 different zinc finger transcription factors, including ZNF84, and several still poorly annotated genes such as KLHL7, MRS2, or the Selenophosphate synthetase 1 (SEPHS1. Interestingly, a large set of genes was also found to code for proteins involved in the ubiquitination and proteasome pathway. Upon hESC differentiation into embryoid bodies, the transcription of this pathway declined. In vitro, we observed a selective sensitivity of hESC to the inhibition of the activity of the proteasome. Conclusion These results shed light on the gene networks that are concurrently overexpressed by the two human cell types with somatic cell reprogramming properties.

    The increase in proliferation and the lack of differentiation of cancer cells resemble what occur in the embryonic stem cells during physiological process of embryogenesis. There are also striking similarities in the behaviour between the invasive placental cells and invasive cancer cells. In the present study, microarrays were used to analyse the global expression of microRNAs in a human embryonic stem cell line (i.e. HUES-17) and four colorectal cancer (CRC) cell lines (i.e. LoVo, SW480, HT29 and Caco-2) with different metastatic potentialities. Only the expression of miR-26b was significant decreased in HUES-17s and LoVo cells, compared with other three cell lines (P cell growth and the induction of apoptosis in LoVo cells in vitro, and the inhibition of tumour growth in vivo. Moreover, the potential targets of miR-26b was predicted by using bioinformatics, and then the predicted target genes were further validated by comparing gene expression profiles between LoVo and NCM460 cell lines. Four genes (TAF12, PTP4A1, CHFR and ALS2CR2) with intersection were found to be the targets of miR-26b. MetaCore network analysis further showed that the regulatory pathways of miR-26b were significantly associated with the invasiveness and metastasis of CRC cells. These data suggest that miR-26b might serve as a novel prognostic factor and a potential therapeutic target for CRC.

    Smallpox, caused by variola virus, was a terror for civilizations around the world for more than 3000 years. Although the disease is eradicated, hundreds of variola virus isolates are kept in two WHO-collaborating facilities, one in USA and one in Russia. In spite of several agreements on destruction, it is now doubtful that these virus isolates will be destroyed. Variola virus may exist in other places and may be used as a biological weapon in war or for terror. Further research on variola virus is thus essential in order to achieve a better understanding of the pathogenicity of the virus and to develop new anti-variola virus vaccines and antiviral drugs.

  14. Molecular evolution of the human immunoglobulin E response: high incidence of shared mutations and clonal relatedness among epsilon VH5 transcripts from three unrelated patients with atopic dermatitis

    Science.gov (United States)

    1993-01-01

    We have analyzed the nucleotide sequences of 19 epsilon VH5 transcripts derived from in vivo isotype switched peripheral blood B cells of three patients with atopic dermatitis. Comparison with the patients' own germline VH5 gene segments revealed that the epsilon transcripts were derived from both functional members of the human VH5 gene family and harbored numerous somatic mutations (range 5-36 per VH5 gene). In two patients, we detected clonally related but diverged transcripts, permitting the construction of a genealogical tree in one patient. We observed a high proportion of shared silent (S) and replacement (R) mutations among epsilon VH5 sequences derived from all three individuals, even among transcripts descending from the two different germline VH5 gene segments. A remarkably high number of these mutations is shared with previously reported VH5 genes encoding antibodies with defined specificities. The shared S mutations, and likely a fraction of the R mutations, appear to mark preferential sites ("hot spots") of somatic hypermutations in human VH5 genes. The distribution of R and S mutations over complementarity determining region and framework regions in the majority of VH regions deviated from that characteristic of antigen-driven immune response. We hypothesize that the V regions of immunoglobulin E-bearing B cells have accumulated "selectively neutral" mutations over extended periods of clonal expansion, resulting in unusual R/S ratios. We propose that the molecular characteristics of the epsilon VH regions in atopic dermatitis may be representative of antigens that recurrently or chronically stimulate the immune system.

  15. Analysis of a summary network of co-infection in humans reveals that parasites interact most via shared resources.

    Griffiths, Emily C; Pedersen, Amy B; Fenton, Andy; Petchey, Owen L

    2014-05-07

    Simultaneous infection by multiple parasite species (viruses, bacteria, helminths, protozoa or fungi) is commonplace. Most reports show co-infected humans to have worse health than those with single infections. However, we have little understanding of how co-infecting parasites interact within human hosts. We used data from over 300 published studies to construct a network that offers the first broad indications of how groups of co-infecting parasites tend to interact. The network had three levels comprising parasites, the resources they consume and the immune responses they elicit, connected by potential, observed and experimentally proved links. Pairs of parasite species had most potential to interact indirectly through shared resources, rather than through immune responses or other parasites. In addition, the network comprised 10 tightly knit groups, eight of which were associated with particular body parts, and seven of which were dominated by parasite-resource links. Reported co-infection in humans is therefore structured by physical location within the body, with bottom-up, resource-mediated processes most often influencing how, where and which co-infecting parasites interact. The many indirect interactions show how treating an infection could affect other infections in co-infected patients, but the compartmentalized structure of the network will limit how far these indirect effects are likely to spread.

    Ettensohn, David B; Frampton, Mark W; Nichols, Joan E; Roberts, Norbert J

    2016-12-01

    The current studies were undertaken to determine the susceptibility of human alveolar macrophages (AMs) to influenza A virus (IAV) infection in comparison with autologous peripheral blood-derived monocytes-macrophages (PBMs). AMs and PBMs were exposed to IAV in vitro and examined for their ability to bind and internalize IAV, and synthesize viral proteins and RNA. PBMs but not AMs demonstrated binding and internalization of the virus, synthesizing viral proteins and RNA. Exposure of AMs in the presence of a sialidase inhibitor or anti-IAV antibody resulted in viral protein synthesis by the cells. Exposure of AMs to fluorescein isothiocyanate-labeled IAV in the presence of anti-fluorescein isothiocyanate antibody also resulted in viral protein synthesis. Thus, human AMs are apparently not susceptible to direct infection by a human IAV but are likely to be infected indirectly in the setting of exposure in the presence of antibody that binds the challenging strain of IAV. © The Author 2016.

    Full Text Available In the mind, language and literature of all people, there are some significant numbers like three, thirty, six, nine, twelve, forty, one hundred and one thousand that are called numbers of perfection. Sometimes one digit is added to these numbers (and the result is seven, thirteen, ten and one thousand and one or is subtracted from them (and the result is five, ninety nine or eleven and the outcome becomes very significant. It seems that these cases have mythological base. Referring to the myth of creation, the writer of the article believes that the number of perfection is another form of death and termination that causes recreation. The continuation of life is shown by subtracting from the numbers of perfection, which means, the cycle has not terminated yet, and even if a cycle is terminated, another is being created. Recreation is shown through adding a figure to the numbers of perfection. The significance of all these numbers has not been in presenting the myth but in defeating the time.

  1. Evidence for a midlife crisis in great apes consistent with the U-shape in human well-being.

    Recently, economists and behavioral scientists have studied the pattern of human well-being over the lifespan. In dozens of countries, and for a large range of well-being measures, including happiness and mental health, well-being is high in youth, falls to a nadir in midlife, and rises again in old age. The reasons for this U-shape are still unclear. Present theories emphasize sociological and economic forces. In this study we show that a similar U-shape exists in 508 great apes (two samples of chimpanzees and one sample of orangutans) whose well-being was assessed by raters familiar with the individual apes. This U-shaped pattern or "midlife crisis" emerges with or without use of parametric methods. Our results imply that human well-being's curved shape is not uniquely human and that, although it may be partly explained by aspects of human life and society, its origins may lie partly in the biology we share with great apes. These findings have implications across scientific and social-scientific disciplines, and may help to identify ways of enhancing human and ape well-being.

    This review considers definitions of the specificity of antibodies including the development of recent concepts of recognition polyspecificity and epitope promiscuity. Using sets of homologous and unrelated peptides derived from the sequences of immunoglobulin and T cell receptor chains we offer operational definitions of cross-reactivity by investigating correlations of either identities in amino acid sequence, or in hydrophobicity/hydrophilicity profiles with degree of binding in enzyme-linked immunosorbent assays. Polyreactivity, or polyspecificity, are terms used to denote binding of a monoclonal antibody or purified antibody preparation to large complex molecules that are structurally unrelated, such as thyroglobulin and DNA. As a first approximation, there is a linear correlation between degree of sequence identity or hydrophobicity/hydrophilicity and antigenic cross-binding. However, catastrophic interchanges of amino acids can occur where changing of one amino acid out of 16 in a synthetic peptide essentially eliminates binding to certain antibodies. An operational definition of epitope promiscuity for peptides is the case where two peptides show little or no identity in amino acid sequence but bind strongly to the same antibody as shown by either direct binding or competitive inhibition. Analysis of antibodies of humans and sharks, the two most divergent species in evolution to express antibodies and the combinatorial immune response, indicates that the capacity for both exquisite specificity and epitope recognition promiscuity are essential conserved features of individual vertebrate antibodies.

    Inexpensive personal robots will soon become available to a large portion of the population. Currently, most consumer robots are relatively simple single-purpose machines or toys. In order to be cost effective and thus widely accepted, robots will need to be able to accomplish a wide range of tasks in diverse conditions. Learning these tasks from demonstrations offers a convenient mechanism to customize and train a robot by transferring task related knowledge from a user to a robot. This avoids the time-consuming and complex process of manual programming. The way in which the user interacts with a robot during a demonstration plays a vital role in terms of how effectively and accurately the user is able to provide a demonstration. Teaching through demonstrations is a social activity, one that requires bidirectional communication between a teacher and a student. The work described in this paper studies how the user's visual observation of the robot and the robot's auditory cues affect the user's ability to teach the robot in a social setting. Results show that auditory cues provide important knowledge about the robot's internal state, while visual observation of a robot can hinder an instructor due to incorrect mental models of the robot and distractions from the robot's movements.

  11. THE COMMON HUMANE SHARING IN DIFFERENT MYTHOLOGIES OF THE LORD OF THE RINGS AND 1984

    Full Text Available John Ronald Reuel Tolkien's collection The Silmarillion, which is a utopic creation myth of Middle-earth, Valinor, Numenor and Beleriand, and his novel The Lord of the Rings, which is a saga taking place only in Middle-earth, seem to be completely irrelevant to George Orwell's dystopian world 1984 at first view but when they are examined in detail, two striking common points would be obvious that these myths support the idea of cultural variety's importance and they consist of a war against cultural dominance. In The Lord of the Rings, it is the battle and collaboration of cultures that makes sense in the mythological surrounding of the plot; the creatures come together to defend their cultural history against a single body; Sauron and the Orcs under his rule. As for 1984, the reader is presented with the struggle of a couple, Winston and Julia, to continue their cultural heritage against the dictatorship of Ingsoc which offers the society with an artificial and prototypical culture.

  14. Being a Modern Human: essentialist and hierarchical approaches to the emergence of 'modern human behaviour'

    Directory of Open Access Journals (Sweden)

    Terry Hopkinson

    2013-06-01

    Full Text Available The emergence of the modern human mind and modern human behaviour is a prominent issue in palaeolithic archaeology. The consensus has been that modernity, understood in terms of increased rates of innovation and the emergence of symbolism, is enabled by a heritable neurophysiology unique to Homo sapiens. This consensus is characterised as biological essentialist in that it understands modernity as genotypically specified and unique to Homo sapiens. 'Archaic' hominins such as the Neanderthals are understood to have lacked the modern neuroanatomical genotype and therefore to have been innately incapable of modern cognition and behaviour. The biological-essentialist programme, however, is facing a serious challenge as evidence for innovation and symbolism is found in the archaeological records of the Eurasian Middle Palaeolithic and the African Middle Stone Age. An alternative programme is emerging that understands modern human behaviour as an emergent property of social, demographic and ecological dynamics. It is argued that this programme is currently inadequate since it cannot explain the emergence of symbolically charged material culture and relies on inexorable long-term population growth. It is suggested here that the problem is better understood in terms of hierarchy theory, a body of ideas concerned with systems organised on multiple scales. Palaeolithic behaviour is reconceptualised as social practice emerging from a multi-scale knowledge system. It is shown that enhancements in the rate at which knowledgeable practices disseminate through social fields – the social transmission of knowledge - will have the effect of increasing the likelihood that novel practices will be incorporated into long-term structuring principles and thus become persistent practices. They will also effect a scalar convergence of domains of knowledgeability such that technical practices become incorporated into the construction of personhood as meaningful or

  16. Xmrk, kras and myc transgenic zebrafish liver cancer models share molecular signatures with subsets of human hepatocellular carcinoma.

    Directory of Open Access Journals (Sweden)

    Weiling Zheng

    Full Text Available Previously three oncogene transgenic zebrafish lines with inducible expression of xmrk, kras or Myc in the liver have been generated and these transgenic lines develop oncogene-addicted liver tumors upon chemical induction. In the current study, comparative transcriptomic approaches were used to examine the correlation of the three induced transgenic liver cancers with human liver cancers. RNA profiles from the three zebrafish tumors indicated relatively small overlaps of significantly deregulated genes and biological pathways. Nevertheless, the three transgenic tumor signatures all showed significant correlation with advanced or very advanced human hepatocellular carcinoma (HCC. Interestingly, molecular signature from each oncogene-induced zebrafish liver tumor correlated with only a small subset of human HCC samples (24-29% and there were conserved up-regulated pathways between the zebrafish and correlated human HCC subgroup. The three zebrafish liver cancer models together represented nearly half (47.2% of human HCCs while some human HCCs showed significant correlation with more than one signature defined from the three oncogene-addicted zebrafish tumors. In contrast, commonly deregulated genes (21 up and 16 down in the three zebrafish tumor models generally showed accordant deregulation in the majority of human HCCs, suggesting that these genes might be more consistently deregulated in a broad range of human HCCs with different molecular mechanisms and thus serve as common diagnosis markers and therapeutic targets. Thus, these transgenic zebrafish models with well-defined oncogene-induced tumors are valuable tools for molecular classification of human HCCs and for understanding of molecular drivers in hepatocarcinogenesis in each human HCC subgroup.

  17. The human core of the shared socioeconomic pathways: Population scenarios by age, sex and level of education for all countries to 2100.

    Kc, Samir; Lutz, Wolfgang

    2017-01-01

    This paper applies the methods of multi-dimensional mathematical demography to project national populations based on alternative assumptions on future, fertility, mortality, migration and educational transitions that correspond to the five shared socioeconomic pathways (SSP) storylines. In doing so it goes a significant step beyond past population scenarios in the IPCC context which considered only total population size. By differentiating the human population not only by age and sex-as is conventionally done in demographic projections-but also by different levels of educational attainment the most fundamental aspects of human development and social change are being explicitly addressed through modeling the changing composition of populations by these three important individual characteristics. The scenarios have been defined in a collaborative effort of the international Integrated Assessment Modeling community with the medium scenario following that of a major new effort by the Wittgenstein Centre for Demography and Global Human Capital (IIASA, OEAW, WU) involving over 550 experts from around the world. As a result, in terms of total world population size the trajectories resulting from the five SSPs stay very close to each other until around 2030 and by the middle of the century already a visible differentiation appears with the range between the highest (SSP3) and the lowest (SSP1) trajectories spanning 1.5 billion. The range opens up much more with the SSP3 reaching 12.6 billion in 2100 and SSP1 falling to 6.9 billion which is lower than today's world population.

    Fjalland, Emmy Laura Perez

    In urban areas sharing cultures, services and economies are rising. People share, rent and recycle their homes, cars, bikes, rides, tools, cloths, working space, knowhow and so on. The sharing culture can be understood as mobilities (Kesselring and Vogl 2013) of goods, values and ideas reshaping...... our cities. The sharing economy has the power to democratise access the urban space, resources and raw materials (Steen Nielsen 2008; Harvey 2000); it holds the ability to change the current dominant understandings and structures of economy and growth (Steen Nielsen 2008); solve emerging environmental...... and trust. (Thomsen 2013; Bauman 2000; Beck 1992; Giddens 1991). The sharing economy is currently hyper trendy but before claiming capitalism as dead we need to understand the basics of the sharing economies and cultures asking who can share and what will we share. Furthermore it is crucial to study what...

    The first radiation protection frameworks were initiated in the early 20. century and focused on the protection of humans. Protection frameworks for non-human species were developed later, based on the human protection system as well as that used to protect the environment from adverse effects of chemicals. These two radiation protection frameworks have to some degree developed quite separately from each other over the last few decades, and it is a source of debate as to what extent the integration of the two is possible. This presentation critically reviews some of the key aspects of integrating human and non-human assessment frameworks, including both conceptual and practical issues, and focuses on five main topics: 1) the conceptual consideration of humans as part of ecosystems, rather than a separate entity; 2) the consistency and potential harmonisation of underlying data and transfer model parameters; 3) consideration of different life stages and life histories in radiation protection and the implications for exposure, dose and effects; 4) calculation of doses, including modelling approaches, spatial and temporal variability and biokinetic modelling; and 5) benchmarks and screening values. Similarities and differences between the two existing frameworks are highlighted and the feasibility of integrating the two discussed. Our recommendations on how to further integrate, where achievable and warranted, are given. Document available in abstract form only. (authors)

    Byron, Paul; Albury, Kath; Evers, Clifton

    2013-05-01

    In today's media environment, information is not simply passed from producers to consumers, but is mediated by participants of new media cultures, including information on sexual health. In focus groups held in Sydney and regional Australia in 2011, we asked young people aged 16-22 about the potential for sexual health promotion via Facebook and other social media. Our findings point to the complex ways in which young people use social media, and the unlikelihood of traditional take-home sexual health messages having traction in social media spaces. Five key aspects which emerged were: the participatory culture of social network sites; the stigma of sexual health, especially sexually transmitted infections (STIs); young people's careful presentations of self; privacy concerns; and the importance of humour in sexual health messaging. Fears of bullying and gossip (or 'drama') were also likely to prevent the dissemination of sexual health messages in this environment. However, humorous online videos were noted by participants as a significant way to avoid stigma and enable the sharing of sexual health information. The young people in our study were interested in sexual health information, but did not want to access it at the cost of their own sense of comfort and belonging in their social networks. Any sexual health promotion within these sites must be understood as a site-specific intervention. Copyright © 2013 Reproductive Health Matters. Published by Elsevier Ltd. All rights reserved.

  2. Th2/1 Hybrid Cells Occurring in Murine and Human Strongyloidiasis Share Effector Functions of Th1 Cells

    Directory of Open Access Journals (Sweden)

    Cristin N. Bock

    2017-06-01

    Full Text Available Infections by the soil-transmitted threadworm Strongyloides stercoralis affect 30–100 million people worldwide, predominantly in tropic and sub-tropic regions. Here we assessed the T helper cell phenotypes in threadworm-infected patients and experimental murine infections with focus on CD4+ T cells co-expressing markers of Th2 and Th1 differentiation. We show that mice infected with the close relative S. ratti generate strong Th2 responses characterized by the expansion of CD4+ GATA-3+ cells expressing IL-4/-5/-13 in blood, spleen, gut-draining lymph nodes, lung and gut tissue. In addition to conventional Th2 cells, significantly increased frequencies of GATA-3+T-bet+ Th2/1-hybrid cells were detected in all organs and co-expressed Th2- and Th1-cytokines at intermediate levels. Assessing the phenotype of blood-derived CD4+ T cells from South Indian patients infected with S. stercoralis and local uninfected control donors we found that GATA-3 expressing Th2 cells were significantly increased in the patient cohort, coinciding with elevated eosinophil and IgE/IgG4 levels. A fraction of IL-4+CD4+ T cells simultaneously expressed IFN-γ hence displaying a Th2/1 hybrid phenotype. In accordance with murine Th2/1 cells, human Th2/1 cells expressed intermediate levels of Th2 cytokines. Contrasting their murine counterparts, human Th2/1 hybrids were marked by high levels of IFN-γ and rather low GATA-3 expression. Assessing the effector function of murine Th2/1 cells in vitro we found that Th2/1 cells were qualified for driving the classical activation of macrophages. Furthermore, Th2/1 cells shared innate, cytokine-driven effector functions with Th1 cells. Hence, the key findings of our study are that T helper cells with combined characteristics of Th2 and Th1 cells are integral to immune responses of helminth-infected mice, but also occur in helminth-infected humans and we suggest that Th2/1 cells are poised for the instruction of balanced immune

    2016-01-01

    Does our brain treat non-biological movements (e.g. moving abstract shapes or robots) in the same way as human movements? The current work tested whether the movement of a non-biological rectangular object, believed to be based on a human action is represented within the observer's motor system. A novel visuomotor priming task was designed to pit true imitative compatibility, due to human action representation against more general stimulus response compatibility that has confounded previous belief experiments. Stimulus response compatibility effects were found for the object. However, imitative compatibility was found when participants repeated the object task with the belief that the object was based on a human finger movement, and when they performed the task viewing a real human hand. These results provide the first demonstration that non-biological stimuli can be represented as a human movement if they are believed to have human agency and have implications for interactions with technology and robots.

    Sustainable ecosystem services supply is the basis of regional sustainable development, and human beings can satisfy and improve their well-being through ecosystem services consumption. To understand the relationships between ecosystem services supply and consumption and human well-being is of vital importance for coordinating the relationships between the conservation of ecosystem services and the improvement of human well-being. This paper summarized the diversity, complexity, and regionality of ecosystem services supply, the diversity and indispensability of ecosystem services consumption, and the multi-dimension, regionality, and various evaluation indices of human well-being, analyzed the uncertainty and multi-scale correlations between ecosystem services supply and consumption, and elaborated the feedback and asynchronous relationships between ecosystem services and human well-being. Some further research directions for the relationships between ecosystem services supply and consumption and human well-being were recommended.

    2015-01-01

    Human prosociality is one of the defining characteristics of our species, yet the ontogeny of altruistic behavior remains poorly understood. The evolution of widespread food sharing in humans helped shape cooperation, family formation, life history, language, and the development of economies of scale. While the behavioral and ecological correlates of food sharing among adults are widely studied, very little is known about food sharing among children. Here, in the first study to analyze the food sharing patterns of hunter-gatherer children, we show that while sharing may be biased towards kin, reciprocity characterizes the majority of all sharing dyads, both related and unrelated. These data lend support to the recent claim that discrimination among kin might be linked with reciprocal altruism theory. Furthermore, we show that age positively correlates with an increase in sharing, both in frequency and amount, supporting recent suggestions that prosocial behaviors and egalitarianism develop strongly in middle childhood when children acquire the normative rules of their society.

    2002-01-01

    Knowledge about human beings is an integral part of any intelligent agent ofconsiderable significance. Delimiting, modeling and acquiring such knowledge are the centraltopics of this paper. Because of the tremendous complexity in knowledge of human beings, weintroduce a top-level ontology of human beings from the perspectives of psychology, sociology,physiology and pathology. This ontology is not only an explicit conceptualization of humanbeings, but also an efficient way of acquiring and organizing relevant knowledge.

  17. Robotic Nudges: The Ethics of Engineering a More Socially Just Human Being.

    2016-02-01

    Robots are becoming an increasingly pervasive feature of our personal lives. As a result, there is growing importance placed on examining what constitutes appropriate behavior when they interact with human beings. In this paper, we discuss whether companion robots should be permitted to "nudge" their human users in the direction of being "more ethical". More specifically, we use Rawlsian principles of justice to illustrate how robots might nurture "socially just" tendencies in their human counterparts. Designing technological artifacts in such a way to influence human behavior is already well-established but merely because the practice is commonplace does not necessarily resolve the ethical issues associated with its implementation.

    Human collaboration in distributed knowledge sharing groups depends on the functionality of information and communication technologies (ICT) to support performance. Since many of these dynamic environments are constrained by time limits, knowledge must be shared efficiently by adapting the level of information detail to the specific situation. This paper focuses on the process of knowledge and context sharing with and without mediation by ICT, as well as issues to be resolved when determining appropriate ICT channels. Both technology-rich and non-technology examples are discussed.

    Kenrick et al. (2010, this issue) make an important contribution by presenting a theory of human needs within an evolutionary framework. In our opinion, however, this framework bypasses the human uniqueness that Maslow intended to capture in his theory. We comment on the unique power of culture in shaping human motivation at the phylogenetic, ontogenetic, and proximate levels. We note that culture-gene coevolution may be a more promising lead to a theory of human motivation than a mammalcentric evolutionary perspective. © The Author(s) 2010.

  1. Natural infection of Plasmodium brasilianum in humans: Man and monkey share quartan malaria parasites in the Venezuelan Amazon.

    The quartan malaria parasite Plasmodium malariae is the widest spread and best adapted human malaria parasite. The simian Plasmodium brasilianum causes quartan fever in New World monkeys and resembles P. malariae morphologically. Since the genetics of the two parasites are nearly identical, differing only in a range of mutations expected within a species, it has long been speculated that the two are the same. However, no naturally acquired infection with parasites termed as P. brasilianum has been found in humans until now. We investigated malaria cases from remote Yanomami indigenous communities of the Venezuelan Amazon and analyzed the genes coding for the circumsporozoite protein (CSP) and the small subunit of ribosomes (18S) by species-specific PCR and capillary based-DNA sequencing. Based on 18S rRNA gene sequencing, we identified 12 patients harboring malaria parasites which were 100% identical with P. brasilianum isolated from the monkey, Alouatta seniculus. Translated amino acid sequences of the CS protein gene showed identical immunodominant repeat units between quartan malaria parasites isolated from both humans and monkeys. This study reports, for the first time, naturally acquired infections in humans with parasites termed as P. brasilianum. We conclude that quartan malaria parasites are easily exchanged between humans and monkeys in Latin America. We hypothesize a lack of host specificity in mammalian hosts and consider quartan malaria to be a true anthropozoonosis. Since the name P. brasilianum suggests a malaria species distinct from P. malariae, we propose that P. brasilianum should have a nomenclatorial revision in case further research confirms our findings. The expansive reservoir of mammalian hosts discriminates quartan malaria from other Plasmodium spp. and requires particular research efforts.

    在Mumcu模型的基础上,建立一个人力资本密集型企业与人力资本有关薪酬谈判的模型,即人力资本凭借其专用性使其投资重要性不断攀升,在与企业薪酬谈判中的话语权也不断增强.在这种情况下,关键性的人力资本已不仅限于获取劳动市场上的均衡工资,更可以与企业分享其创造的价值.反观,当人力资本密集型企业生产对关键性人力资本的依赖性不断增强并且难以控制时,企业只有通过与其分享租金以协调人力资本与企业保持合作,实现共赢.%Based one the model of Mumcu, this paper tries to model a negotiation about wage between human-capital-intensive firms and human capital. The importance of human capital ^upgrades gradually by its specific investment and human capital's power of the negotiation about wage boosts up gradually too. Under the circumstance, critical human capital not only can get the equilibrium wage of the labor market, but also can share the value which is created by him and the firm. On the contrary, when the dependency of human capital of human-capital-intensive firms reinforces and human-capital-intensive firms become difficult to control human capital, the firm just can coordinate the human capital to cooperate with the firm by profit-sharing and realize the win-win condition.

  3. Can Plant Viruses Cross the Kingdom Border and Be Pathogenic to Humans?

    Full Text Available Phytoviruses are highly prevalent in plants worldwide, including vegetables and fruits. Humans, and more generally animals, are exposed daily to these viruses, among which several are extremely stable. It is currently accepted that a strict separation exists between plant and vertebrate viruses regarding their host range and pathogenicity, and plant viruses are believed to infect only plants. Accordingly, plant viruses are not considered to present potential pathogenicity to humans and other vertebrates. Notwithstanding these beliefs, there are many examples where phytoviruses circulate and propagate in insect vectors. Several issues are raised here that question if plant viruses might further cross the kingdom barrier to cause diseases in humans. Indeed, there is close relatedness between some plant and animal viruses, and almost identical gene repertoires. Moreover, plant viruses can be detected in non-human mammals and humans samples, and there are evidence of immune responses to plant viruses in invertebrates, non-human vertebrates and humans, and of the entry of plant viruses or their genomes into non-human mammal cells and bodies after experimental exposure. Overall, the question raised here is unresolved, and several data prompt the additional extensive study of the interactions between phytoviruses and non-human mammals and humans, and the potential of these viruses to cause diseases in humans.

    The human's Micro-Doppler signatures resulting from breathing, arm, foot and other periodic motion can provide valuable information about the structure of the moving parts and may be used for identification and classification purposes. In this paper, we carry out simulate with FDTD method and through wall experiment with UWB radar for human being's periodic motion detection. In addition, Advancements signal processing methods are presented to classify and to extract the human's periodic motion characteristic information, such as Micro-Doppler shift and motion frequency. Firstly, we apply the Principal Component Analysis (PCA) with singular value decomposition (SVD) to denoise and extract the human motion signal. Then, we present the results base on the Hilbert-Huang transform (HHT) and the S transform to classify and to identify the human's micro-Doppler shift characteristics. The results demonstrate that the combination of UWB radar and various processing methods has potential to detect human's Doppler signatures effectively.

    Full Text Available We have tested serum samples from 24 patients with multifocal motor neuropathy (MMN for reactivity to ganglioside GM1 and to Gal(β1–3GalNAc-bearing glycoproteins isolated from human peripheral nerve and from Campylobacter jejuni (Cj serotype O:19. IgM anti-GM1 antibodies were detected by ELISA in 11 patients (45.8% with MMN and in only one subject (4% from the control group. Western blots showed positive reactivity of sera from 6 patients (25% with MMN to several Gal(β1–3GalNAc-bearing glycoproteins from human peripheral nerve and from Cj O:19 isolates. Sera from three patients (12.5% with MMN showed positively reactive bands with similar electrophoretic mobility in all isolates (60–62 kDa, 48–51 kDa, 42 kDa, and 38 kDa. All six patients showed positive reactivity to 48–52 kDa protein isolated from human peripheral nerve. Increased titer of IgG antibodies to 60–62 kDa protein isolated from Cj O:19 associated with Guillain-Barré syndrome was detected in three patients, and their serum showed also IgG positive reactivity to peripheral nerve antigen with the same electrophoretic mobility. One of these patients had a previous history of Cj infection which suggests the possibility that Cj may be also involved in the pathogenesis of MMN.

    Naive CD4(+) T cells differentiate into specific effector subsets-Th1, Th2, Th17, and T follicular helper (Tfh)-that provide immunity against pathogen infection. The signaling pathways involved in generating these effector cells are partially known. However, the effects of mutations underlying human primary immunodeficiencies on these processes, and how they compromise specific immune responses, remain unresolved. By studying individuals with mutations in key signaling pathways, we identified nonredundant pathways regulating human CD4(+) T cell differentiation in vitro. IL12Rβ1/TYK2 and IFN-γR/STAT1 function in a feed-forward loop to induce Th1 cells, whereas IL-21/IL-21R/STAT3 signaling is required for Th17, Tfh, and IL-10-secreting cells. IL12Rβ1/TYK2 and NEMO are also required for Th17 induction. Strikingly, gain-of-function STAT1 mutations recapitulated the impact of dominant-negative STAT3 mutations on Tfh and Th17 cells, revealing a putative inhibitory effect of hypermorphic STAT1 over STAT3. These findings provide mechanistic insight into the requirements for human T cell effector function, and explain clinical manifestations of these immunodeficient conditions. Furthermore, they identify molecules that could be targeted to modulate CD4(+) T cell effector function in the settings of infection, vaccination, or immune dysregulation. © 2016 Ma et al.

    2017-10-01

    Biophysics, just by looking at its name, indicates an interdisciplinary scientific activity, although the notion of interdisciplinarity, as such, seems to be not widely or specifically discussed by biophysicists. The same seems to have happened as well in the early stages of the development of cybernetics, notably in Norbert Wiener's writings. This situation seems to contrast with what has happened in subsequent developments of cybernetics ideas, notably in general system theory and cognitive sciences. After a few general reflections on the notion of interdisciplinarity, its sophisticated variants and the path leading to the birth of cognitive science, we shall refer to Wiener's thought to extracts aspects and indications that could be useful today, also for what concerns the social responsibility of scientists, which could be seen as stemming from a very general form of interdisciplinarity. After a few general reflections on the notion of interdisciplinarity, its sophisticated variants and the path leading to the birth of cognitive science, we shall refer to Wiener's thought to extracts aspects and indications that could be useful today, also for what concerns the social responsibility of scientists.

    Full Text Available This editorial presents the theme and approach of the themed issue “Humanity as a Contested Concept: Relations between Disability and ‘Being Human’”. The way in which the concept of humanity is or must be related to disability is critically investigated from different disciplinary perspectives in the themed issue, which is, moreover, situated in the field of disability studies and related to discussions about posthumanism. The argument is made that humanity is a concept that needs to be constantly reflected upon from a disability studies perspective. Finally, the contributions of the themed issue are briefly outlined.

    This is discussion about the relationship between elderly human beings with ostomy and their environments care, under the perspective of Complexity Edgar Morin. An axis holds the reflection: environments of care for elderly humans with ostomy. In this sense, we present three types of environment that surround the context of elderly humans with ostomy: home environment, group environment and hospital environment. This brings, as a social contribution, a new look about resizing caring of elderly humans with ostomy in their environment. It is considered that the environment hosting this human being contains a diversity of feelings, emotions, experiences; it binds multiple meanings, from the Complexity perspective, about the relationship between the environment and the caring process.

    Full Text Available Allegedly, Heidegger never quite finished Being and Time: his initial intention had consisted in the determination of the meaning of Being as such, apart from Dasein’s own existentiality. Afterwards, however, and despite the growing public excitement revolving around the published unfinished version of his project, his preoccupations, thematic conceptuality and very language, apparently started to shift away towards a strange and unfamiliar stance which he would never leave. Quite surely, his Nazi flirtation and subsequent withdrawal did not help in bringing clarity over this. On the other hand, this was not necessarily unexpected (although not necessarily to be expected, as well. What I mean to say is that for someone reading Being and time in spirit and not in law, the possibility of such a substantive rethought of his initial scheme is present throughout the work. One’s changing one’s mind with respect to oneself is, after all, one of the basic possibilities conveyed by Dasein’s achieved resoluteness [Entschlossenheit]. Furthermore, despite his apparent reorientation, I think we can speak of some sort of attitudinal unity between Heidegger’s initial and later work, conceptually mediated by the relationship between Dasein’s Being-unto-death [Sein-zum-Tode] and the so called concealedness [Verborgenheit] of Being.. That is precisely what I aim to lay bare through this conceptual reconstruction of some of his later works: (i On the Essence of Truth (1930 and (ii Letter on Humanism (1946. Basically, I will try to show that if in Being and Time he tried to come to Being from Dasein, in his later work he tries to get to Da-sein from Being, fact which unsurprisingly brought along some reconsiderations but that, broadly speaking, essentially amounts to what he set out to do in his initial ontological project. Surprisingly, the most concrete instance of this pendulation between Dasein and Being is to be found, at least to my knowledge, in

  18. Shared molecular and functional frameworks among five complex human disorders: a comparative study on interactomes linked to susceptibility genes.

    Directory of Open Access Journals (Sweden)

    Ramesh Menon

    Full Text Available BACKGROUND: Genome-wide association studies (gwas are invaluable in revealing the common variants predisposing to complex human diseases. Yet, until now, the large volumes of data generated from such analyses have not been explored extensively enough to identify the molecular and functional framework hosting the susceptibility genes. METHODOLOGY/PRINCIPAL FINDINGS: We investigated the relationships among five neurodegenerative and/or autoimmune complex human diseases (Parkinson's disease--Park, Alzheimer's disease--Alz, multiple sclerosis--MS, rheumatoid arthritis--RA and Type 1 diabetes--T1D by characterising the interactomes linked to their gwas-genes. An initial study on the MS interactome indicated that several genes predisposing to the other autoimmune or neurodegenerative disorders may come into contact with it, suggesting that susceptibility to distinct diseases may converge towards common molecular and biological networks. In order to test this hypothesis, we performed pathway enrichment analyses on each disease interactome independently. Several issues related to immune function and growth factor signalling pathways appeared in all autoimmune diseases, and, surprisingly, in Alzheimer's disease. Furthermore, the paired analyses of disease interactomes revealed significant molecular and functional relatedness among autoimmune diseases, and, unexpectedly, between T1D and Alz. CONCLUSIONS/SIGNIFICANCE: The systems biology approach highlighted several known pathogenic processes, indicating that changes in these functions might be driven or sustained by the framework linked to genetic susceptibility. Moreover, the comparative analyses among the five genetic interactomes revealed unexpected genetic relationships, which await further biological validation. Overall, this study outlines the potential of systems biology to uncover links between genetics and pathogenesis of complex human disorders.

    A technique for dynamically sharing information includes executing a sharing policy indicating when to share a data object responsive to the occurrence of an event. The data object is created by formatting a data file to be shared with a receiving entity. The data object includes a file data portion and a sharing metadata portion. The data object is encrypted and then automatically transmitted to the receiving entity upon occurrence of the event. The sharing metadata portion includes metadata characterizing the data file and referenced in connection with the sharing policy to determine when to automatically transmit the data object to the receiving entity.

Actually we don’t know a sure potential “reservoir” in animals who are strictly in contact with humans, and it is difficult to understand its epidemiological chain, otherwise the transmissions to humans and from humans to humans. For all these reasons we performed another study on subjects of swine breedings, and among people who work in these breedings, that are in direct contact or not with pigs. Using standardized methodologies, we analyzed 224 faecal specimens of swine and 15 human specimens.We use for identification of D. fragilis the Giemsa stain.These were the results: D. fragilis was observed in 50.9% of pigs and 20% among humans (30% in workers strictly in contact with breedings and pigs, 0% in familiars or other without a closed contact with swines. Other commensal protozoa were observed with variable associations, but in this article we want to analyze the possible transmission from this pigs to humans (and for us this protozoon is undoubtedly a “reservoir” of D. fragilis for humans, and underline two aspects: for the research of this protozoon, standard procedures area mandatory, with a permanent stain, as Giemsa stain, is necessary, and in all humans with various intestinal infections or troubles, particularly “irritable bowel syndrome” (or similar ones, the specimens must be analyzed for D. fragilis.

    The majority of international or national guidelines, specific to human genetics concentrate on actual or potential clinical applications. In contrast, the Ethics Committee of the Human Genome Organisation (HUGO) attempts to provide guidance to the bench scientists engaged in fundamental research in genomics prior to any clinical applications. Often confused as constituting the Human Genome Project (HGP) itself, HUGO's (Human Genome Organization) ultimate goal is to assist in the worldwide collaboration underpinning the HGP. It is an international organisation with 1,229 members in approximately 60 countries. The Ethics Committee is one of HUGO's six international advisory committees. Composed of experts from a number of countries and disciplines, the HUGO Ethics Committee promotes discussion and understanding of social, legal, and ethical issues as they relate to the conduct of, and knowledge derived from, the Genome Initiative. Currently, it has 13 members from 11 difference countries. It has produced statements on the conduct of genetic research, on cloning, and, has most recently presented a 'Statement on Benefit-Sharing', April 11, 2000. The Intellectual Property Committee of HUGO has been active in the controversial area of patenting. The issue of benefit-sharing is one that has its source in the mandate of both committees. How to avoid both commodification of the person through payment for access to DNA and biopiracy with no return to benefits to the families or community? While patents are a legitimate form of recognition for innovation, there seems to be no therapeutic exception to some of its stringent rules and the 'morality' exclusion has lain dormant. The HUGO 'Statement on Benefit-Sharing' examines the issues of defining community, common heritage, distributive justice and solidarity before arriving at its conclusions in benefit-sharing. This communication reviews some of these issues.

    Conservation scientists increasingly recognize that incorporating human values into conservation planning increases the chances for success by garnering broader project acceptance. However, methods for defining quantitative targets for the spatial representation of human well-being priorities are less developed. In this study we employ an approach for identifying regionally important human values and establishing specific spatial targets for their representation based on stakeholder outreach. Our primary objective was to develop a spatially-explicit conservation plan that identifies the most efficient locations for conservation actions to meet ecological goals while sustaining or enhancing human well-being values within the coastal and nearshore areas of the western Lake Erie basin (WLEB). We conducted an optimization analysis using 26 features representing ecological and human well-being priorities (13 of each), and included seven cost layers. The influence that including human well-being had on project results was tested by running five scenarios and setting targets for human well-being at different levels in each scenario. The most important areas for conservation to achieve multiple goals are clustered along the coast, reflecting a concentration of existing or potentially restorable coastal wetlands, coastal landbird stopover habitat and terrestrial biodiversity, as well as important recreational activities. Inland important areas tended to cluster around trails and high quality inland landbird stopover habitat. Most concentrated areas of importance also are centered on lands that are already conserved, reflecting the lower costs and higher benefits of enlarging these conserved areas rather than conserving isolated, dispersed areas. Including human well-being features in the analysis only influenced the solution at the highest target levels. PMID:28241018

    As nursing is an art that emphasizes the nature of caring it should have humanistic attributes. Humanistic education of a nursing professional should emphasize a person-centered perspective in order to foster cultivation of the humanities and infuse the spirit of humane care into medical practice. Cultivation of humanism refers to the emotional level of personal-affective experience that blends humanistic science and aesthetic experience to enhance nurse observational abilities. The ability generated by self-awareness and reflection can trigger deep empathy and empathetic performance, which is ideal humanistic-nursing behavior in nursing staff. Traditional nursing education focuses on acquiring professional knowledge and largely ignores the cultivation of a humanist spirit. To help nurses adjust to the rapidly changing environment of nursing care and demonstrate a professional and humane character, in addition to advocating for a humane medical environment, the six Es of humanistic-nursing education (Example, Explanation, Exhortation, Environment, Experience, Expectation) should be promoted. The six Es are essential to building a framework to cultivate humanistic education strategies and strengthen humanist content in nursing education. In order to instill deeply the spirit of humanistic care in nursing and make the nursing-care process more humane, these ideals must be emphasized in nursing education to raise the level of humanism.

    Full Text Available Abstract Background The "common disease – common variant" hypothesis and genome-wide association studies have achieved numerous successes in the last three years, particularly in genetic mapping in human diseases. Nevertheless, the power of the association study methods are still low, in particular on quantitative traits, and the description of the full allelic spectrum is deemed still far from reach. Given increasing density of single nucleotide polymorphisms available and suggested by the block-like structure of the human genome, a popular and prosperous strategy is to use haplotypes to try to capture the correlation structure of SNPs in regions of little recombination. The key to the success of this strategy is thus the ability to unambiguously determine the haplotype allele sharing status among the members. The association studies based on haplotype sharing status would have significantly reduced degrees of freedom and be able to capture the combined effects of tightly linked causal variants. Results For pedigree genotype datasets of medium density of SNPs, we present two methods for haplotype allele sharing status determination among the pedigree members. Extensive simulation study showed that both methods performed nearly perfectly on breakpoint discovery, mutation haplotype allele discovery, and shared chromosomal region discovery. Conclusion For pedigree genotype datasets, the haplotype allele sharing status among the members can be deterministically, efficiently, and accurately determined, even for very small pedigrees. Given their excellent performance, the presented haplotype allele sharing status determination programs can be useful in many downstream applications including haplotype based association studies.

    One of the most important applications of transgenic animals for medical purposes is to transplant their organs into human's body, an issue which has caused a lot of ethical and scientific discussions. we can divide the ethical arguments to two comprehensive groups; the first group which is known as deontological critiques (related to the action itself regardless of any results pointing the human or animal) and the second group, called the consequentialist critiques (which are directly pointing the consequences of the action). The latter arguments also can be divided to two subgroups. In the first one which named anthropocentrism, just humankind has inherent value in the moral society, and it studies the problem just from a human-based point of view while in second named, biocentrism all the living organism have this value and it deals specially with the problem from the animal-based viewpoint. In this descriptive-analytic study, ethical issues were retrieved from books, papers, international guidelines, thesis, declarations and instructions, and even some weekly journals using keywords related to transgenic animals, organ, and transplantation. According to the precautionary principle with the strong legal and ethical background, due to lack of accepted scientific certainties about the safety of the procedure, in this phase, transplanting animal's organs into human beings have the potential harm and danger for both human and animals, and application of this procedure is unethical until the safety to human will be proven.

    Pharmacogenomics is a hybrid field of experimental science at the intersection of human disease genetics and clinical pharmacology sharing applications of the new genomic technologies. But this hybrid field is not yet stable or fully integrated, nor is science policy in pharmacogenomics fully equipped to resolve the challenges of this emerging hybrid field. The disciplines of human disease genetics and clinical pharmacology contain significant differences in their scientific practices. Whereas clinical pharmacology originates as an experimental science, human disease genetics is primarily observational in nature. The result is a significant asymmetry in scientific method that can differentially impact the degree to which gene-environment interactions are discerned and, by extension, the study sample size required in each discipline. Because the number of subjects enrolled in observational genetic studies of diseases is characteristically viewed as an important criterion of scientific validity and reliability, failure to recognize discipline-specific requirements for sample size may lead to inappropriate dismissal or silencing of meritorious, although smaller-scale, craft-based pharmacogenomic investigations using an experimental study design. Importantly, the recognition that pharmacogenomics is an experimental science creates an avenue for systematic policy response to the ethical imperative to prospectively pursue genetically customized therapies before regulatory approval of pharmaceuticals. To this end, we discuss the critical role of interdisciplinary engagement between medical sciences, policy, and social science. We emphasize the need for development of shared standards across scientific, methodologic, and socioethical epistemologic divides in the hybrid field of pharmacogenomics to best serve the interests of public health.

    To probe the correlation between the postmortem interval (PMI) and the DNA degradation of costicartilage and dental pulp cells in human being after death, and to seek a new method for estimating PMI. The image cytometry was used to measure the DNA degradation under different ambient temperatures (30-35 degrees C, 15-20 degrees C) in 0-15 days after death. The average DNA content of two kinds of tissue was degradated with the prolongation of PMI. But there was a plateau period of 0-4 days for dental pulp cells of human being in 15-20 degrees C. There was a high negative correlativity PPMI. PMI could be estimated accurately according to the DNA degradation of costicartilage and dental pulp cells in human being after death.

    Conservationists are increasingly engaging with the concept of human well-being to improve the design and evaluation of their interventions. Since the convening of the influential Sarkozy Commission in 2009, development researchers have been refining conceptualizations and frameworks to understand and measure human well-being and are starting to converge on a common understanding of how best to do this. In conservation, the term human well-being is in widespread use, but there is a need for guidance on operationalizing it to measure the impacts of conservation interventions on people. We present a framework for understanding human well-being, which could be particularly useful in conservation. The framework includes 3 conditions; meeting needs, pursuing goals, and experiencing a satisfactory quality of life. We outline some of the complexities involved in evaluating the well-being effects of conservation interventions, with the understanding that well-being varies between people and over time and with the priorities of the evaluator. Key challenges for research into the well-being impacts of conservation interventions include the need to build up a collection of case studies so as to draw out generalizable lessons; harness the potential of modern technology to support well-being research; and contextualize evaluations of conservation impacts on well-being spatially and temporally within the wider landscape of social change. Pathways through the smog of confusion around the term well-being exist, and existing frameworks such as the Well-being in Developing Countries approach can help conservationists negotiate the challenges of operationalizing the concept. Conservationists have the opportunity to benefit from the recent flurry of research in the development field so as to carry out more nuanced and locally relevant evaluations of the effects of their interventions on human well-being. © 2014 The Authors.

  13. INTERACTION BETWEEN HUMAN BEING AND URBAN CULTURE SPACE: ONE OF THE MOTIVATIONS FOR HIGHER EDUCATION INTERNATIONALISATION

    Directory of Open Access Journals (Sweden)

    Hu Liang Cai

    2016-06-01

    Full Text Available Introduction: the objective of this paper is to deeply and clearly explain the internationalisation of higher education from the aspect of the integration of human being with urban cultural space. Materials and Methods: the methods used in the research are mainly analytical and descriptive ones enabling to show how the integration of human being and urban cultural space promote and influence the internationalisation of higher education. Results: the motivation for the internationalisation of higher education is closely interrelated with that of urbanisation. Besides the economic and political incentives, modern urban culture, caused by globalisation, also plays a very important role in encouraging higher education internationalisation. Discussion and Conclusions: the appearance of higher education internationalisation is mediated by the alteration of the existing environment of urban culture space against the background of city internationalisation. Human beings’ need for self-assurance in urban culture space helps to stimulate the internationalisation of higher education, and human beings promote the development of modern culture space and their separation in urban culture space accelerates the development of higher education. From the perspective of higher education internationalisation, to sort out the cultural motivation for higher education and find its suitable form for the city’s internationalisation is crucial for adjusting the orientation and guaranteeing the efficacy of higher education internationalisation. From the aspect of human beings’ development, the separation between urban space and human beings caused by the city’s ongoing internationalisation is a pressing problem to be solved. From the aspect of the construction of urban culture space, as an important means of retaining human beings’ equilibrium, urban culture promotes the internationalisation of higher education.

    Little research focuses on the association between immune thrombocytopenic purpura and human immunodeficiency virus infection in Taiwan. This study investigated whether immune thrombocytopenic purpura might be an early hematologic manifestation of undiagnosed human immunodeficiency virus infection in Taiwan. We conducted a retrospective population-based cohort study using data of individuals enrolled in Taiwan National Health Insurance Program. There were 5472 subjects aged 1-84 years with a new diagnosis of immune thrombocytopenic purpura as the purpura group since 1998-2010 and 21,887 sex-matched and age-matched, randomly selected subjects without immune thrombocytopenic purpura as the non-purpura group. The incidence of human immunodeficiency virus infection at the end of 2011 was measured in both groups. We used the multivariable Cox proportional hazards regression model to measure the hazard ratio and 95 % confidence interval (CI) for the association between immune thrombocytopenic purpura and human immunodeficiency virus infection. The overall incidence of human immunodeficiency virus infection was 6.47-fold higher in the purpura group than that in the non-purpura group (3.78 vs. 0.58 per 10,000 person-years, 95 % CI 5.83-7.18). After controlling for potential confounding factors, the adjusted HR of human immunodeficiency virus infection was 6.3 (95 % CI 2.58-15.4) for the purpura group, as compared with the non-purpura group. We conclude that individuals with immune thrombocytopenic purpura are 6.47-fold more likely to have human immunodeficiency virus infection than those without immune thrombocytopenic purpura. We suggest not all patients, but only those who have risk factors for human immunodeficiency virus infection should receive testing for undiagnosed human immunodeficiency virus infection when they develop immune thrombocytopenic purpura.

  1. Computational Characterization of Exogenous MicroRNAs that Can Be Transferred into Human Circulation.

    Directory of Open Access Journals (Sweden)

    Full Text Available MicroRNAs have been long considered synthesized endogenously until very recent discoveries showing that human can absorb dietary microRNAs from animal and plant origins while the mechanism remains unknown. Compelling evidences of microRNAs from rice, milk, and honeysuckle transported to human blood and tissues have created a high volume of interests in the fundamental questions that which and how exogenous microRNAs can be transferred into human circulation and possibly exert functions in humans. Here we present an integrated genomics and computational analysis to study the potential deciding features of transportable microRNAs. Specifically, we analyzed all publicly available microRNAs, a total of 34,612 from 194 species, with 1,102 features derived from the microRNA sequence and structure. Through in-depth bioinformatics analysis, 8 groups of discriminative features have been used to characterize human circulating microRNAs and infer the likelihood that a microRNA will get transferred into human circulation. For example, 345 dietary microRNAs have been predicted as highly transportable candidates where 117 of them have identical sequences with their homologs in human and 73 are known to be associated with exosomes. Through a milk feeding experiment, we have validated 9 cow-milk microRNAs in human plasma using microRNA-sequencing analysis, including the top ranked microRNAs such as bta-miR-487b, miR-181b, and miR-421. The implications in health-related processes have been illustrated in the functional analysis. This work demonstrates the data-driven computational analysis is highly promising to study novel molecular characteristics of transportable microRNAs while bypassing the complex mechanistic details.

    Direct reprogramming of human somatic cells into pluripotency has broad implications in generating patient-specific induced pluripotent stem (iPS) cells for disease modeling and cellular replacement therapies. However, the low efficiency and safety issues associated with generation of human iPS cells have limited their usage in clinical settings. Cell types can significantly influence reprogramming efficiency and kinetics. To date, human iPS cells have been obtained only from a few cell types. Here, we report for the first time rapid and efficient generation of iPS cells from human amniotic fluid-derived cells (hAFDCs) via ectopic expression of four human factors: OCT4/SOX2/KLF4/C-MYC. Significantly, typical single iPS cell colonies can be picked up 6 days after viral infection with high efficiency. Eight iPS cell lines have been derived. They can be continuously propagated in vitro and express pluripotency markers such as AKP, OCT4, SOX2, SSEA4, TRA-1-60 and TRA-1-81, maintaining the normal karyotype. Transgenes are completely inactivated and the endogenous OCT4 promoter is adequately demethylated in the established iPS cell lines. Moreover, various cells and tissues from all three germ layers are found in embryoid bodies and teratomas, respectively. In addition, microarray analysis demonstrates a high correlation coefficient between hAFDC-iPS cells and human embryonic stem cells, but a low correlation coefficient between hAFDCs and hAFDC-iPS cells. Taken together, these data identify an ideal human somatic cell resource for rapid and efficient generation of iPS cells, allowing us to establish human iPS cells using more advanced approaches and possibly to establish disease- or patient-specific iPS cells.

    The chief objective of respective study was to investigate the seroprevalence of brucellosis among occupationally exposed human beings in Himachal Pradesh. A total of 165 serum samples that were obtained from human beings from various regions of the state were screened through a battery of serological tests which included RBPT, STAT, 2-MET, dot-ELISA and indirect-ELISA. 165 of human sera samples included 42 from veterinarians, 40 shepherds, 35 livestock owners, 20 workers at veterinary hospitals/clinics, 16 abattoir workers and 12 veterinary pharmacists. The overall seroprevalence of brucellosis among occupationally exposed human beings was observed to be 6.66% showing highest in abattoir workers (18.75%) followed by pharmacists (8.33%), veterinarians (7.14%), and livestock owners (5.71%) and shepherds (5.00%). In humans it is prevalent as an occult infection or under diagnosed disease, especially; in case of abattoir workers the highest seropositivity for brucella agglutinins was observed. Indirect-ELISA and Dot-ELISA proved best in the diagnosis of brucellosis.

    This report presents a comprehensive set of recommendations for protection of human beings who are trafficked for the purpose of organ removal or are targeted for such trafficking. Developed by an interdisciplinary group of international experts under the auspices of the project Trafficking in Human Beings for the Purpose of Organ Removal (also known as the HOTT project), these recommendations are grounded in the view that an individual who parts with an organ for money within an illegal scheme is ipso facto a victim and that the crime of trafficking in human beings for the purpose of organ removal (THBOR) intersects with the crime of trafficking in organs. Consequently, the protection of victims should be a priority for all actors involved in antitrafficking activities: those combating organ-related crimes, such as health organizations and survivor support services, and those combating trafficking in human beings, such as the criminal justice sectors. Taking into account the special characteristics of THBOR, the authors identify 5 key stakeholders in the protection of human beings trafficked for organ removal or targeted for such trafficking: states, law enforcement agencies and judiciary, nongovernmental organizations working in the areas of human rights and antitrafficking, transplant centers and health professionals involved in transplant medicine, and oversight bodies. For each stakeholder, the authors identify key areas of concern and concrete measures to identify and protect the victims of THBOR. The aim of the recommendations is to contribute to the development of a nonlegislative response to THBOR, to promote the exchange of knowledge and best practices in the area of victim protection, and to facilitate the development of a policy-driven action plan for the protection of THBOR victims in the European Union and worldwide.

    Bombyx mori (silkworm) is the most famous lepidopteran in Japan. B. mori has long been used in the silk industry and also as a model insect for agricultural research. In recent years, B. mori has attracted interest in its potential for use in pathological analysis of model animals. For example, the human macular carotenoid transporter was discovered using information of B. mori carotenoid transporter derived from yellow-cocoon strain. The B. mori carotenoid transport system is useful in human studies. To develop a human disease model, we characterized the human homologs of B. mori, and by constructing KAIKO functional annotation pipeline, and to analyze gene expression profile of a unique B. mori mutant strain using microarray analysis. As a result, we identified a novel molecular network involved in Parkinson's disease. Here we describe the potential use of a spontaneous mutant silkworm strain as a human disease model. We also summarize recent progress in the application of genomic information for annotation of human homologs in B. mori. The B. mori mutant will provide a clue to pathological mechanisms, and the findings will be helpful for the development of therapies and for medical drug discovery.

  9. Immigration Policy Reform in the United States: Reframing the enforcement discourse to fight human trafficking and promote shared prosperity

    2013-11-01

    Full Text Available At the time of this writing, the United States Senate has passed the Border Security, Economic Opportunity, and Immigration Modernization Act (S. 744. The bill is the product of countless political compromises and would significantly transform the U.S. immigration system. This paper explores shortcomings in U.S. immigration policy, deconstructs provisions in the bill, and makes policy proposals that would protect and empower migrants who interface with the U.S. immigration system in dangerous and under-regulated environments at the border and in sending communities, in labour recruitment networks, and in the U.S. workforce. Ultimately, the paper seeks to continue an ongoing conversation that challenges the criminalisation of migration which perpetuates vulnerability, and instead forwards rights-based policies that would promote shared prosperity.

  10. The big challenges in modeling human and environmental well-being [version 1; referees: 3 approved

    2016-04-01

    Full Text Available This article is a selective review of quantitative research, historical and prospective, that is needed to inform sustainable development policy. I start with a simple framework to highlight how demography and productivity shape human well-being. I use that to discuss three sets of issues and corresponding challenges to modeling: first, population prehistory and early human development and their implications for the future; second, the multiple distinct dimensions of human and environmental well-being and the meaning of sustainability; and, third, inequality as a phenomenon triggered by development and models to examine changing inequality and its consequences. I conclude with a few words about other important factors: political, institutional, and cultural.

  12. Benefit sharing: it's time for a definition.

    Science.gov (United States)

    Schroeder, D

    2007-04-01

    Benefit sharing has been a recurrent theme in international debates for the past two decades. However, despite its prominence in law, medical ethics and political philosophy, the concept has never been satisfactorily defined. In this conceptual paper, a definition that combines current legal guidelines with input from ethics debates is developed. Philosophers like boxes; protective casings into which they can put concisely-defined concepts. Autonomy is the human capacity for self-determination; beneficence denotes the virtue of good deeds, coercion is the intentional threat of harm and so on. What about benefit sharing? Does the concept have a box and are the contents clearly defined? The answer to this question has to be no. The concept of benefit sharing is almost unique in that various disciplines use it regularly without precise definitions. In this article, a definition for benefit sharing is provided, to eliminate unnecessary ambiguity.

  14. The Earth Sciences, Human Well-Being, and the Reduction of Global Poverty

    Mutter, John C.

    2005-04-01

    Poverty is not solely a social or political matter, nor is it caused simply by population pressures as Thomas Malthus postulated in 1798. A new understanding of poverty is emerging in which natural and environmental drivers, together with social, political, and demographic causes, underpin livelihoods. The Earth sciences, therefore, play a critical role in identifying the deep causes of human suffering and in identifying solutions. The State of the Planet: Why Are So Many So Poor? For far too many, the state of human well-being is bleak. Around one in six human beings-1 billion people-live in extreme poverty, struggling to survive on less than $1 a day; another one sixth of humanity ekes out existence on $2 per day (U.N. Development Programme (UNDP) Human Development Report, 2004; http://hdr.undp.org/2004/). The extreme poor lack all normal attributes of a decent, dignified life: adequate food, housing, sanitation, health care, education, and employment. Some 800 million people lack sufficient nourishment almost every day. It stunts their mental and physical development and shortens their lives, making them susceptible to common illnesses that attack their hunger-weakened bodies. Poor nutrition in mothers and infants is the leading cause of reduced disability-adjusted life years in poor countries [ Economist, 2004].

    Full Text Available I put forward an understanding of evolutionary epistemology that rescues something of the old and venerable idea of freedom, and it means that we as theologians should grasp our very nature realistically, beyond any illusionism and utopian dreams. The author feels that scholars, especially theologians, should firstly take evolution seriously and secondly regard evolutionary epistemology as important as evolution itself, the reason being theologians should know that it is of paramount importance for their systematic-theological intradisciplinary and/or interdisciplinary implications, which is embarking on a way of thinking that regards evolutionary epistemology as a friend in their accommodation of their respective theological fields of interest. This accommodation is substantial as it will enhance their respective theological disciplines as �an exhilarating vision of God�. Evolutionary epistemology takes a pragmatic view of humans. Evolutionary epistemologists question how humans really behave and what the true origin of their behaviour is. In contrast to this programme, many conceptions of humans are based on an idealisation of our species.Intradisciplinary and/or interdisciplinary implications: Evolutionary epistemology takes a pragmatic view of humans.

  16. Meteoric 10Be as a tool to investigate human induced soil fluxes: a conceptual model

    2014-05-01

    The use of meteoric 10Be as a tool to understand long term landscape behavior is becoming increasingly popular. Due its high residence time, meteoric 10Be allows in principle to investigate in situ erosion rates over time scales exceeding the period studied with classical approaches such as 137Cs. The use of meteoric 10Be strongly contributes to the traditional interpretation of sedimentary archives which cannot be unequivocally coupled to sediment production and could provide biased information over longer time scales (Sadler, 1981). So far, meteoric 10Be has successfully been used in geochemical fingerprinting of sediments, to date soil profiles, to assess soil residence times and to quantify downslope soil fluxes using accumulated 10Be inventories along a hill slope. However, less attention is given to the potential use of the tracer to directly asses human induced changes in soil fluxes through deforestation, cultivation and reforestation. A good understanding of the processes governing the distribution of meteoric 10Be both within the soil profile and at landscape scale is essential before meteoric 10Be can be successfully applied to assess human impact. We developed a spatially explicit 2D-model (Be2D) in order to gain insight in meteoric 10Be movement along a hillslope that is subject to human disturbance. Be2D integrates both horizontal soil fluxes and vertical meteoric 10Be movement throughout the soil prolife. Horizontal soil fluxes are predicted using (i) well studied geomorphical laws for natural erosion and soil formation as well as (ii) human accelerated water and tillage erosion. Vertical movement of meteoric 10Be throughout the soil profile is implemented by inserting depth dependent retardation calculated using experimentally determined partition coefficients (Kd). The model was applied to different environments such as (i) the Belgian loess belt, characterized by aeolian deposits enriched in inherited meteoric 10Be, (ii) highly degraded and stony

  17. Ecosystem Services and Human Well-Being: a Participatory Study in a Mountain Community in Portugal

    Directory of Open Access Journals (Sweden)

    Henrique Miguel Pereira

    2005-12-01

    Full Text Available Ecosystem services are essential for human well-being, but the links between ecosystem services and human well-being are complex, diverse, context-dependent, and complicated by the need to consider different spatial and temporal scales to assess them properly. We present the results of a study in the rural community of Sistelo in northern Portugal that formed part of the Portugal Millennium Ecosystem Assessment. The main purpose of our study was to assess the linkages between human well-being and ecosystem services at the local level, as perceived by the community. We used a range of tools that included participatory rural appraisal and rapid rural appraisal as well as other field methods such as direct observation, familiarization and participation in activities, semistructured interviews, trend lines, well-being ranking, and other ranking and scoring exercises. Sistelo has a unique landscape of agricultural terraces that are now being abandoned because of the depopulation of the region, a common trend in mountainous rural areas of Europe. From the community perspective, some components of well-being such as material well-being have been improving, whereas some ecosystem services, e.g., food production, have been declining. Although a few of the local criteria for well-being are closely related to local ecosystem services, most of them are not. People recognize many of the services provided by ecosystems, in particular, provisioning, cultural, and regulating services, although they feel that provisioning services are the most important for well-being. It is apparent that, for the Sistelo community, there is an increasing disconnect between local well-being and at least some local ecosystem services. This disconnect is associated with greater freedom of choice at the local level, which gives the local inhabitants the power to find substitutes for ecosystem services.

    Antibiotic-resistant bacteria were first identified in the 1940s, but while new antibiotics were being discovered at a steady rate, the consequences of this phenomenon were slow to be appreciated. Today, the excessive use of antibiotics compounded by the paucity of new agents on the market has...... meant the problem of antibiotic resistance is fast escalating into a global health crisis. There is no doubt that misuse of these drugs in human beings has contributed to the increasing rates of resistance, but recently the use of antibiotics in food animals and its consequent effect on resistance....... There is a growing concern over the transmission of resistant bacteria via the food chain. Many questions will be difficult to resolve, such as how do you distinguish the fraction of resistance in human beings that originated from animals? If we wait to see evidence that a significant amount of antibiotic resistance...

    Information plays various roles for supporting human activity. Its basic role is to describe objects in the world. Form of representation is first decided, then method of its processing can be defined on its basis. Thus an information processing paradigm is defined. As human activity gets more and more complicated, information also becomes more and more sophisticated. Form of representation and processing method become the more complicated. Sometime in human history symbolic language has been developed. It facilitated representation of things. With the progress of language, information became the more sophisticated one. Development of variety of paradigms became possible by means of language. Each of which has a specific scope of applications There is a lot of information, however, that cannot be captured by symbolic language. Representation and processing of information unable to be symbolized, that is, non-symbolic information processing paradigm is very different from any of symbolic information processing paradigms. These two groups of paradigms divide the whole information world. Most applications have been done within either one of them so far. Progress of human activity requires a paradigm with a larger scope. If any of existing single paradigms cannot satisfy this requirement, a new paradigm must be developed. Integration of different paradigms is becoming a very important approach. However conversion between paradigms is necessary for the purpose and conversion between substantially different paradigms, such as between symbol processing and non-symbol processing,is very difficult. Bridging the gap between these two paradigms is becoming an important issue and is attracting much interest of researchers. Discovery and data mining is one of such issues. There is an interest in the more basic question such as "how could human being acquire language?" To discuss these issues is the major objective of this talk.

  7. The use of live vaccine for vaccination of human beings against brucellosis in the USSR.

    1961-01-01

    The great majority of human brucellosis cases in the USSR are caused by contact with infected sheep and goats. Extensive action has been taken to prevent human infection and to reduce the incidence among farm animals, the main prophylactic measure in recent years being vaccination with live brucellosis vaccine. The author summarizes the steps leading to the development of a satisfactory vaccine and gives a brief description of the method of preparation. Discussing the results obtained, she states that there has been a nearly 60% reduction in the number of human cases over the period 1952-58.The subcutaneous route of administration is usually resorted to, but preliminary figures suggest that cutaneous vaccination is equally effective immunogenically, although in persons who have suffered from active brucellosis it causes strong reactions and may lead to exacerbation of the disease. Research is going forward into the development of a cutaneous vaccine capable of general use.

  8. Are typical human serum BPA concentrations measurable and sufficient to be estrogenic in the general population?

    Mammalian estrogen receptors modulate many physiological processes. Chemicals with structural features similar to estrogens can interact with estrogen receptors to produce biological effects similar to those caused by endogenous estrogens in the body. Bisphenol A (BPA) is a structural analogue of estrogen that binds to estrogen receptors. Exposure to BPA in humans is virtually ubiquitous in industrialized societies, but BPA is rapidly detoxified by metabolism and does not accumulate in the body. Whether or not serum concentrations of BPA in humans are sufficiently high to disrupt normal estrogen-related biology is the subject of intense political and scientific debate. Here we show a convergence of robust methods for measuring or calculating serum concentrations of BPA in humans from 93 published studies of more than 30,000 individuals in 19 countries across all life stages. Typical serum BPA concentrations are orders of magnitude lower than levels measurable by modern analytical methods and below concentrations required to occupy more than 0.0009% of Type II Estrogen Binding Sites, GPR30, ERα or ERβ receptors. Occupancies would be higher, but ≤0.04%, for the highest affinity receptor, ERRγ. Our results show limited or no potential for estrogenicity in humans, and question reports of measurable BPA in human serum.

    2015-12-01

    Governments are becoming interested in the concept of human well-being and how truly to assess it. As an alternative to traditional economic measures, some nations have begun to collect information on citizens' happiness, life satisfaction, and other psychological scores. Yet how could such data actually be used? This paper is a cautious attempt to contribute to thinking on that question. It suggests a possible weighting method to calculate first-order changes in society's well-being, discusses some of the potential principles of democratic 'well-being policy', and (as an illustrative example) reports data on how sub-samples of citizens believe feelings might be weighted.

  15. Bonobos share with strangers.

    Directory of Open Access Journals (Sweden)

    Jingzhi Tan

    Full Text Available Humans are thought to possess a unique proclivity to share with others--including strangers. This puzzling phenomenon has led many to suggest that sharing with strangers originates from human-unique language, social norms, warfare and/or cooperative breeding. However, bonobos, our closest living relative, are highly tolerant and, in the wild, are capable of having affiliative interactions with strangers. In four experiments, we therefore examined whether bonobos will voluntarily donate food to strangers. We show that bonobos will forego their own food for the benefit of interacting with a stranger. Their prosociality is in part driven by unselfish motivation, because bonobos will even help strangers acquire out-of-reach food when no desirable social interaction is possible. However, this prosociality has its limitations because bonobos will not donate food in their possession when a social interaction is not possible. These results indicate that other-regarding preferences toward strangers are not uniquely human. Moreover, language, social norms, warfare and cooperative breeding are unnecessary for the evolution of xenophilic sharing. Instead, we propose that prosociality toward strangers initially evolves due to selection for social tolerance, allowing the expansion of individual social networks. Human social norms and language may subsequently extend this ape-like social preference to the most costly contexts.

    Adenitire, John Olusegun

    2017-04-01

    It is argued that the current policy of the British Medical Association (BMA) on conscientious objection is not aligned with recent human rights developments. These grant a right to conscientious objection to doctors in many more circumstances than the very few recognised by the BMA. However, this wide-ranging right may be overridden if the refusal to accommodate the conscientious objection is proportionate. It is shown that it is very likely that it is lawful to refuse to accommodate conscientious objections that would result in discrimination of protected groups. It is still uncertain, however, in what particular circumstances the objection may be lawfully refused, if it poses risks to the health and safety of patients. The BMA's policy has not caught up with these human rights developments and ought to be changed.

    Phenylalanine hydroxylase (PAH) is an important metabolic enzyme of aromatic amino acids, which is responsible for the irreversible oxidation of phenylalanine to tyrosine. In the present study, the full-length cDNA encoding PAH from Chlamys farreri (designated CfPAH) was cloned by using rapid amplification of cDNA ends (RACE) approaches and expression sequence tag (EST) analysis. The open reading frame of CfPAH encoded a polypeptide of 460 amino acids, and its sequence shared 64.4-74.2% similarity with those of PAHs from other animals. There were an N-terminal regulatory ACT domain and a C-terminal catalytic Biopterin_H domain in the deduced CfPAH protein. The mRNA transcripts of CfPAH could be detected in all the tested tissues, including adductor muscle, mantle, gill, gonad, haemocytes and hepatopancreas. And its expression level in haemocytes was increased significantly during 3-48 h after bacteria Vibrio anguillarum challenge with the highest level (9.1-fold, P phenylalanine to tyrosine within 1 min (nmol min(-1) mg(-1) protein) in vitro. These results indicated collectively that CfPAH, as a homologue of phenylalanine hydroxylase in scallop C. farreri, could be induced by cytokine and involved in the immunomodulation of scallops by supplying the starting material tyrosine for the synthesis of melanin and catecholamines.

    2015-12-01

    Full Text Available Discipline of economics, who already assimilated the mathematical and technical tools as a base for the expression of theory is almost lost its identity as a social science. This process has become visible through some historical breakups. These breakups have scientific, social and economic faces. While the developments in natural sciences had led the economists to imitate physics - since it uses more certain methods as a science; the market society which established after the industrial revolution separated humans from the economic understanding of the past eras. Rationality, which indeed a philosophical concept, purified from its philosophical context and integrated to economics. On the other hand, the mainstream economics which accepts the maximisation of interest as one of the components of human nature prevailed the economics literature. The modern economics’ conception of human had shaped via the steps which we briefly mentioned above. Karl Polanyi (1886-1964 had criticized the human conception of modern economics by using social anthropological methods. He had claimed that market system did not emerged spontaneously, the nature of human did not change throughout history, and primitive economics was totally different from today’s market society since the economic relations were embedded in the other social relations. In this article, we tried to analyse Polanyi’s criticisms on modern economics’ human conception. For this reason, we firstly argued the term rationality in the economic context, since it would be a basis for our subject. Then we emphasized the thesis of “uncahged nature of human” which highlighted by Polanyi, discussions on primitive economies, and the market society which established parallel to the industrial revolution respectively.

    2017-01-01

    Mycobacterium tuberculosis is recognised as the primary cause of human tuberculosis worldwide. However, substantial evidence suggests that the burden of Mycobacterium bovis, the cause of bovine tuberculosis, might be underestimated in human beings as the cause of zoonotic tuberculosis. In 2013, results from a systematic review and meta-analysis of global zoonotic tuberculosis showed that the same challenges and concerns expressed 15 years ago remain valid. These challenges faced by people with zoonotic tuberculosis might not be proportional to the scientific attention and resources allocated in recent years to other diseases. The burden of zoonotic tuberculosis in people needs important reassessment, especially in areas where bovine tuberculosis is endemic and where people live in conditions that favour direct contact with infected animals or animal products. As countries move towards detecting the 3 million tuberculosis cases estimated to be missed annually, and in view of WHO's end TB strategy endorsed by the health authorities of WHO Member States in 2014 to achieve a world free of tuberculosis by 2035, we call on all tuberculosis stakeholders to act to accurately diagnose and treat tuberculosis caused by M bovis in human beings.

    The early emergence of macrophages and their large pattern of tissue distribution during development suggest that they may play a critical role in the initial steps of embryogenesis. In the present study, we show that monocytic cells derived from human embryonic stem cells (hESCs) and from fetal liver follow a differentiation pathway different to that of adult cells, leading to specific functions. Embryonic and fetal monocytic cells differentiated from a CD14(low)CD16(-) precursor to form CD14(high)CD16(+) cells without producing the CD14(high)CD16(-) cell population that predominates in adult peripheral blood. Both demonstrated an enhanced expression of genes encoding tissue-degrading enzymes, chemokines, and scavenger receptors, as was previously reported for M2 macrophages. Compared with adult blood monocytes, embryonic and fetal monocytic cells secreted high amounts of proteins acting on tissue remodeling and angiogenesis, and most of them expressed the Tie2 receptor. Furthermore, they promoted vascular remodeling in xenotransplanted human tumors. These findings suggest that the regulation of human fetal and embryonic monocytic cell differentiation leads to the generation of cells endowed mainly with anti-inflammatory and remodeling functions. Trophic and immunosuppressive functions of M2-polarized macrophages link fetus and tumor development, and hESCs offer a valuable experimental model for in vitro studies of mechanisms sustaining these processes.

    cDNA clones encoding two receptor proteins involved in the binding of human interleukin 5 (hIL5) have been isolated. A first class codes for an IL5-specific chain (hIL5R alpha). The major transcript of this receptor gene, as analyzed in both HL-60 eosinophilic cells and eosinophilic myelocytes grown from cord blood, encodes a secreted form of this receptor. This soluble hIL5R alpha has antagonistic properties. A second component of the hIL5R is found to be identical to the beta chain of the human granulocyte-macrophage colony-stimulating factor (GM-CSF) high affinity receptor. The finding that IL5 and GM-CSF share a receptor subunit provides a molecular basis for the observation that these cytokines can partially interfere with each other's binding and have highly overlapping biological activities on eosinophils.

  6. The contribution of animals to human well-being: a veterinary family practice perspective.

    Timmins, Richard P

    2008-01-01

    There is considerable evidence that humans can benefit both physically and emotionally from a relationship with companion animals, a phenomenon known as the human-animal bond (HAB). This has not only increased the demand for veterinary services to meet the needs of these non-human family members and their owners, but it has also transformed the nature of those services from reactive medicine and surgery to proactive prevention and wellness. The emotional component of the HAB requires the veterinarian to have a solid understanding of the nature of the attachment between client and pet, and an ability to educate the client about proper care of the animal in order to optimize the relationship. Paying attention to the relationship between client and patient also positions the veterinary family practitioner to refer the client to appropriate community resources for physical, emotional, or other needs of the client that may become apparent during the veterinarian-client interaction. By achieving physical and mental health objectives for patients and collaborating with human health care services, the veterinary family practitioner contributes to the well-being of both patient and client. This new face of veterinary family practice requires research and education in fields that have not traditionally been a part of veterinary training.

    The cities of today present requirements that are dissimilar to those of the past. There are cities where the industrial and service sectors are in decline, and there are other cities that are just beginning their journey into the technological and industrial sectors. In general, the political and social realms have been restructured in terms of economics, which has resulted in an entirely different shape to the primitive structures of civilization. As people begin to understand the dynamic nature of landscapes, they stop seeing landscapes as a static scene. Sustainable cities must be simultaneously economically viable, socially just, politically well managed and ecologically sustainable to maximize human comfort. The present research suggests a multi-disciplinary approach for attaining a holistic understanding of urban environmental quality and human well-being in relation to sustainable urban development.

    Full Text Available Introduction. The incorporation of mobile phones in the daily life of human being not only alters space and time dimensions, but it also changes the perception and the way we relate with the ecosystem. Methodology. The state of the art is analyzed from the technological concept of intimacy, used by Boyce and Hancock, which describes the levels of interaction between man and technology. Then, a methodology to explore issues increasingly pressing is proposed, especially, concerning the delimitation of public and private spheres and the interaction in the common space. Results and conclusions. Following in particular the theories of Castells, Heidegger, Meyrowitz and Habermas; a set of categories for deepening the concepts of spatialization, willingness and profile are articulated. These concepts are identified as key elements in this first stage of the project for the analysis of the human being as a communication portal.

    World Health Organization recommends that girls, ages 9-13 years, get the human papilloma virus (HPV) vaccine. Global Alliance for Vaccines Initiative, which provides low-cost vaccine to eligible countries, requires that an additional intervention to be offered alongside the vaccine. We systematically searched and assessed the published literature in lower- and middle-income countries to identify effective interventions. We conducted systematic searches of four databases: PubMed, EMBASE, Global Index Medicus Regional Databases, and Cochrane Reviews for effective adolescent health interventions that could be delivered with the HPV vaccine in the following areas: (1) iron and folic acid supplementation (iron alone or with folic acid); (2) voucher delivery and cash transfer programs; (3) hand washing and soap provision; (4) vision screening; (5) promotion of physical activity/exercise; (6) menstrual hygiene education; (7) sexual and reproductive health education; (8) human immunodeficiency virus prevention activities; and (9) condom promotion, condom use skill building, and demonstration. We found limited evidence of consistent positive impact. Iron supplementation reduced iron-deficiency anemia and raised serum ferritin levels. Promotion of physical activity lowered blood pressure and reduced weight gain. Sexual and reproductive health and human immunodeficiency virus interventions improved adolescent communication with adults but did not influence behavioral outcomes. Countries should consider locally relevant and proven interventions to be offered alongside the HPV vaccine. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

  12. Toxicovigilance: a new approach for the hazard identification and risk assessment of toxicants in human beings.

    Science.gov (United States)

    Descotes, Jacques; Testud, François

    2005-09-01

    The concept of toxicovigilance encompasses the active detection, validation and follow-up of clinical adverse events related to toxic exposures in human beings. Poison centers are key players in this function as poisoning statistics are essential to define the cause, incidence and severity of poisonings occurring in the general population. In addition, the systematic search for unexpected shifts in the recorded causes of poisonings, e.g., following the introduction of a new product, or change in the formulation or recommended use of an old product, allows for a rapid detection of potential adverse health consequences and the implementation of preventive or corrective measures. However, toxicovigilance is genuinely a medical and not only a statistical approach of human toxicity issues. In contrast to epidemiology, toxicovigilance is based on the in-depth medical assessment of acute or chronic intoxications on an individual basis, which requires detailed information that poison centers can rarely obtain via emergency telephone calls and that epidemiologists cannot collect or process. Validation of this medical information must primarily be based on toxicological expertise to help identify causal links between otherwise unexplained pathological conditions and documented toxic exposures. Thus, toxicovigilance can contribute to hazard identification and risk assessment by providing medically validated data which are often overlooked in the process of risk assessment. So far, very few structured toxicovigilance systems have been set up and hopefully national and international initiatives will bridge this gap in our knowledge of the toxicity of many chemicals and commercial products in human beings.

  13. Can biosemiotics be a "science" if its purpose is to be a bridge between the natural, social and human sciences?

    Science.gov (United States)

    Brier, Søren

    2015-12-01

    Central to the attempt to develop a biosemiotics has been the discussion of what it means to be scientific. In Marcello Barbieri's latest argument for leaving Peircean biosemiotics and creating an alternative code-biology the definition of what it means to be scientific plays a major role. For Barbieri "scientific knowledge is obtained by building machine-like models of what we observe in nature". Barbieri interestingly claims that - in combination with the empirical and experimental basis - mechanism is virtually equivalent to the scientific method. The consequences of this statement seem to be that the optimal type of knowledge science can produce about living system is to model them as machines. But the explicit goal of a Peircean semiotically based biosemiotics is (also) to model living systems as cognitive and communicative systems working on the basis of meaning and signification. These two concepts are not part of the mechanistic models of natural science today, not even of cognitive science. Barbieri tries to solve this problem by introducing a new concept of biological meaning that is separate from the Peircean biosemiotics and then add Peirce's semiotics on top. This article argues why this view is inconsistent on the grounds that Peirce's semiotic paradigm only gives meaning in its pragmaticist conception of a fallibilist view of science, which again is intrinsic connected to its non-mechanistic metaphysics of Tychism, Synechism and Agapism. The core of the biosemiotic enterprise is to establish another type of trans- and interdisciplinary wissenschaft than the received view of "science".

  14. Sharing values, sharing a vision

    1993-12-31

    Teamwork, partnership and shared values emerged as recurring themes at the Third Technology Transfer/Communications Conference. The program drew about 100 participants who sat through a packed two days to find ways for their laboratories and facilities to better help American business and the economy. Co-hosts were the Lawrence Livermore National Laboratory and the Lawrence Berkeley Laboratory, where most meetings took place. The conference followed traditions established at the First Technology Transfer/Communications Conference, conceived of and hosted by the Pacific Northwest Laboratory in May 1992 in Richmond, Washington, and the second conference, hosted by the National Renewable Energy Laboratory in January 1993 in Golden, Colorado. As at the other conferences, participants at the third session represented the fields of technology transfer, public affairs and communications. They came from Department of Energy headquarters and DOE offices, laboratories and production facilities. Continued in this report are keynote address; panel discussion; workshops; and presentations in technology transfer.

    This conference was organized a month after the publication by the International Energy Agency (IEA) of the 2007 World Energy Outlook (WEO) study. The energy situation at that time was marked by the repercussions on the environment and on the security of supplies in relation with the accelerated development of China and India. This document gathers the transparencies of the two presentations given at this conference. The first presentation by Fatih Birol, Chief Economist at the IEA, is entitled 'World Energy Outlook 2007: China and India Insights'. It presents the Cooperation with China's National Development and Reform Commission (NDRC) and Energy Research Institute (ERI), and with India's Energy and Resources Institute (TERI) for the establishment of energy scenarios. Then the different scenarios are reviewed: Reference Scenario, Alternative Policy Scenario and 450 Stabilisation Case, High Growth Scenario (China/India). Finally, a full global update of projections (all scenarios) is presented and the impact of China and India on global economy, energy markets and environment is analyzed. The conclusions are as follows: - Global energy system is on an increasingly unsustainable path; - China and India are transforming the global energy system by their sheer size; - Challenge for all countries is to achieve transition to a more secure, lower carbon energy system; - New policies now under consideration would make a major contribution; - Next 10 years are critical (The pace of capacity additions will be most rapid, Technology will be 'locked-in' for decades, Growing tightness in oil and gas markets); - Challenge is global so solutions must be global. The second presentation by Jean-Charles Hourcade (CIRED) is entitled 'The WEO 2007 A few comments about the Emerging Giants... and us'. The presentation focusses on 4 points: - What implications of higher growth in the Asian Giants on the world economy through higher pressure on

    2016-09-01

    Full Text Available In classic theories on professions and professionalism, the relationship between professionals and citizens are typically seen as based on formal, scientific knowledge and expertise and thus as functionally specific. This conception may, however, be too simplistic for professionals working in close and frequent interactions with citizens. The article therefore theoretically discusses the assumption of a functional specific relationship and the possibility of other ways (e.g., personal and emotional that professionals can relate to citizens. Further, the article explores the professional-citizen relationship seen from the side of welfare professionals, by exploring sensemaking with regard to professional identities, roles, and discretion making. The analysis demonstrate how most professionals combine a logic based on formal knowledge and training with a personal, relational, and emotion-based logic when describing their work and the relationship to citizens. Implications for our theoretical and normative understanding of professionalism are discussed.

    2010-08-01

    Full Text Available That ministry is to be given back to the laity is a laudable proposition. However, the level of development in many township and village communities is still such that a strong leadership and management facilitation role is demanded of the pastor. In such contexts, the pastor is also the only one who is always available for church tasks. The point of departure of this article was that the pastor is primarily a facilitator who assumes the tasks of a leader, a manager and a servant. The Trinitarian office of Christ is taken as model. Christian leadership, as discussed from a systems perspective, is seen as enabling rather than hegemonic. The pastor fulfils the seven leadership functions in order to equip the saints for their Christian service. Church management is redefined as a process which takes place in meaningful collaboration with others, over against the objectification found in conventional definitions which focus on ‘getting things done through people’. This article discussed servant leadership and service provision as the central purpose of Christian leadership.

    Sun fluxes induce additional heterogeneous thermal constraints in buildings and may also lead to discomfort for the inhabitant. To calculate the local thermal sensation of a human being totally or partially situated in the sunlight, the solar radiation inside a room and its detailed distribution on parts of the human body are modeled. The present study focuses on the solar gains part of a complete modeling tool simulating an occupied building. The irradiated areas are calculated with a ray tracing method taking shadow into account. Solar fluxes are computed. Fluxes can be absorbed by each surface or reflected. The reflected fluxes are then absorbed at the next impact. A multi-node thermoregulation model (MARCL) represents the thermal behavior of the human body and all its heat exchanges with the environment. The thermal transient simulation of the whole occupied building is performed in TRNSYS simulation software. In the case presented here, the results show that, when a person is inside the building, the skin and clothing temperatures of the irradiated segments increase more or less depending on the segments but the global thermal equilibrium of the body is maintained thanks to strong physiological reactions.

    Full Text Available In this introductory essay, we explore definitions of the ‘sharing economy’, a concept indicating both social (relational, communitarian and economic (allocative, profit-seeking aspects which appear to be in tension. We suggest combining the social and economic logics of the sharing economy to focus on the central features of network enabled, aggregated membership in a pool of offers and demands (for goods, services, creative expressions. This definition of the sharing economy distinguishes it from other related peer-to-peer and collaborative forms of production. Understanding the social and economic motivations for and implications of participating in the sharing economy is important to its regulation. Each of the papers in this special issue contributes to knowledge by linking the social and economic aspects of sharing economy practices to regulatory norms and mechanisms. We conclude this essay by suggesting future research to further clarify and render intelligible the sharing economy, not as a contradiction in terms but as an empirically observable realm of socio-economic activity.

  1. Fourier series analysis of the electrophysiological pattern of fatigue in healthy human beings, after curare administration.

    Real time computer analysis of the electrophysiological development of muscular fatigue after small doses of d-tubocurarine (TC), has been examined in anesthetized human beings. As compared to a decrease of frequency in the control measurements, previous studies have shown an increase of the frequency of spikes after TC administration. The present experiments were carried out on the biceps brachii of 8 healthy human volunteers maintained in isometric contraction against a constant counter load until complete fatigue occurred. The Fourier spectrum analysis showed a statistically significant shift to lower frequencies before, and a milder statistically non significant shift after TC. These results may indicate that under mild curarization the early phase of muscular contraction requires a higher number of large motor units and thus, at a later stage of the contraction the pool of available large motor units becomes smaller. This conclusion supports the hypothesis that mild curarization causes a state of initial muscular fatigue.

    Over the past decade, there has been a growing openness about the importance of human factors in forensic work. However, most of it focused on cognitive bias, and neglected issues of workplace wellness and stress. Forensic scientists work in a dynamic environment that includes common workplace pressures such as workload volume, tight deadlines, lack of advancement, number of working hours, low salary, technology distractions, and fluctuating priorities. However, in addition, forensic scientists also encounter a number of industry-specific pressures, such as technique criticism, repeated exposure to crime scenes or horrific case details, access to funding, working in an adversarial legal system, and zero tolerance for "errors". Thus, stress is an important human factor to mitigate for overall error management, productivity and decision quality (not to mention the well-being of the examiners themselves). Techniques such as mindfulness can become powerful tools to enhance work and decision quality. © 2017 American Academy of Forensic Sciences.

    Distributions of Earth's species are changing at accelerating rates, increasingly driven by human-mediated climate change. Such changes are already altering the composition of ecological communities, but beyond conservation of natural systems, how and why does this matter? We review evidence that climate-driven species redistribution at regional to global scales affects ecosystem functioning, human well-being, and the dynamics of climate change itself. Production of natural resources required for food security, patterns of disease transmission, and processes of carbon sequestration are all altered by changes in species distribution. Consideration of these effects of biodiversity redistribution is critical yet lacking in most mitigation and adaptation strategies, including the United Nation's Sustainable Development Goals.

    2015-11-01

    It is a principal open question whether noninvasive imaging methods in humans can decode information encoded at a spatial scale as fine as the basic functional unit of cortex: cortical columns. We addressed this question in five magnetoencephalography (MEG) experiments by investigating a columnar-level encoded visual feature: contrast edge orientation. We found that MEG signals contained orientation-specific information as early as approximately 50 ms after stimulus onset even when controlling for confounds, such as overrepresentation of particular orientations, stimulus edge interactions, and global form-related signals. Theoretical modeling confirmed the plausibility of this empirical result. An essential consequence of our results is that information encoded in the human brain at the level of cortical columns should in general be accessible by multivariate analysis of electrophysiological signals.

  5. Problems with measuring peripheral oxytocin: can the data on oxytocin and human behavior be trusted?

    McCullough, Michael E; Churchland, Patricia Smith; Mendez, Armando J

    2013-09-01

    Research on the neurobiological and behavioral effects of oxytocin (OT), as well as on its possible therapeutic applications, has intensified in the past decade. Accurate determination of peripheral OT levels is essential to reach meaningful conclusions and to motivate, support and inform clinical interventions. Different, but concordant, methods for measuring plasma OT have been developed over the past four decades, but since 2004 several commercially available methods have been favored in research with humans. Evaluation of these methods reveals that they lack reliability when used on unextracted samples of human fluids, and that they tag molecules in addition to OT, yielding estimates that are wildly discrepant with an extensive body of earlier findings that were obtained using methods that are well validated, but more laborious. An accurate, specific, and readily available method for measuring OT that can be adopted as the standard in the field is urgently needed for advances in our understanding of OT's roles in cognition and behavior.

    Full Text Available The European Union (EU is an early signatory of the United Nations Convention against Transnational Organized Crime. During the past decade, the EU has been undertaking various measures to conform to the "Protocol to Prevent, Suppress and Punish Trafficking in Persons". The mitigating strategy has been largely based on the enforcement of existing and new laws, inside as well as outside of the EU. To date, the results have been largely ineffective. Addressing the societal and economic elements of home and host countries could be a more enduring means to alleviate the problem of trafficking in human beings.

    The ecosystem services concept is seen by many as a useful paradigm to support decision-making at the complex interface between science, policy and practice. However, to be successful, it requires a strong willingness for collaboration and joint understanding. In support of this aspiration, OPPLA is being developed as a web portal to enable European communities to better manage ecosystems for human well-being and livelihoods. OPPLA will provide access to a variety of online resources such as tools, case studies, lessons learned, videos, manuals and training and educational materials. It will also provide expert forums and spaces for discussions between researchers, practitioners and decision makers. Hence a critical aspect of the success of OPPLA is the co-evolution of communities of practice. An example of a community of practice is the recently launched Ecosystem Services Community - Scotland (ESCom-Scotland; escomscotland.wordpress.com). ESCom-Scotland aims to support better management of Scotland's natural resources by helping to establish a community of practice between individuals and groups involved in the science, policy and practice behind sustainable ecosystem management. It aspires to encourage the sharing of ideas, increase collaboration and to initiate a support network for those engaging with the ecosystem services concept and it will use the OPPLA resources to support these activities. OPPLA is currently at the developmental stage and was instigated by two large European Commission funded research projects: OPERAs (www.operas-project.eu) and OpenNESS (www.openness-project.eu), with a combined budget of ca. €24m. These projects aim to improve understanding of how ecosystem services contribute to human well-being in different social-ecological systems. Research will establish whether, how and under what conditions the ecosystem services concept can move beyond the academic domain towards practical implementation in support of sustainable ecosystem

    Governments are becoming interested in the concept of human well-being and how truly to assess it. As an alternative to traditional economic measures, some nations have begun to collect information on citizens’ happiness, life satisfaction, and other psychological scores. Yet how could such data actually be used? This paper is a cautious attempt to contribute to thinking on that question. It suggests a possible weighting method to calculate first-order changes in society’s well-being, discusses some of the potential principles of democratic ‘well-being policy’, and (as an illustrative example) reports data on how sub-samples of citizens believe feelings might be weighted.

    The question about features of human reaction on the sharp environmental physical activity (EPA) changes is considered by international group of physicists and physicians on the base of results of monitoring of human health state in different cities spread on latitude and longitude. The typical reaction of human body on the influences, exceeding the organisms' ability to adaptation, is of stress-reaction character. From medical point of view there is no significant difference for human body -what external (EPA) agent shocked an organism (emotional or some physical threats). First attempt of the organism to restore its homeostasis is stress-reaction, being universal for many stress-factors. Its main stages (such as alarm, resistance, and exhaustion) are detectable by different medical equipments, but we tried to find universal, non-traumatic method of daily measurements, enough sensitive and appropriate for observation of people reaction both on weather and space weather (geomagnetic activity) changes. The experiment was based on a method of electrical conductivity measurements of biologically active (acupunctural) points of human skin. The used method (electroacupunctural method by Dr. R.Voll) is very sensitive to current state of an organism and characterize the functional condition of different organs and systems of human body and allows to express so-called "group's health status" in the units, suitable for comparison with meteorological and heliogeophysical parameters. We conduct the parallel investigations as a part of collaborative study in different geographic latitudes-longitudes (Baku:40° 23'43"N -49° 52'56"E, Troitsk (Moscow region): 55° 28'40"N -37° 18'42"E, Yakutsk: 62° 02'00"N -129° 44'00"E).

    It's a complicated China I find, like all westerners, that most Chinese communication is 'complicated'. I think this comes from the strong Chi- nese preference for indirect communica- tion. Often in business, the real picture would only become clear after many hours of around-the-houses discus- sion, which doesn't even stop when the contract is agreed and signed. Patience and cross-checking are vital, but labori- ous. No requirement is either straight- forward or direct, even if the customer is in a hurry. They want to explore all the.

    Human serum albumin (HSA), being the most abundant carrier protein in blood and a modern day clinical tool for drug delivery, attracts high attention among biologists. Hence, its unfolding/refolding strategies and exogenous/endogenous ligand binding preference are of immense use in therapeutics and clinical biochemistry. Among its fellow proteins albumin is known to carry almost every small molecule. Thus, it is a potential contender for being a molecular cargo/or nanovehicle for clinical, biophysical and industrial purposes. Nonetheless, its structure and function are largely regulated by various chemical and physical factors to accommodate HSA to its functional purpose. This multifunctional protein also possesses enzymatic properties which may be used to convert prodrugs to active therapeutics. This review aims to highlight current overview on the binding strategies of protein to various ligands that may be expected to lead to significant clinical applications.

    A 19-year-old woman with a history of juvenile laryngeal papillomatosis (JLP), treated since childhood with multiple resections, was admitted with symptoms of pneumonia. A chest X-ray and CAT-scan revealed multiple lung cysts and a bronchoalveolar lavage detected human papilloma virus 11. The patient responded well to antibiotics. A body plethysmography showed small lung volumes and low diffusion capacity for carbon monoxide, but normal volume diffusion capacity divided by alveolar volume. Pulmonary cystic disease should be considered when patients with JLP have symptoms of pneumonia.

    Here we report a case of carbapenem resistance in a human clinical isolate that was found to be closely related to the newly described environmental species Acinetobacter indicus. This strain harboured the blaOXA-23 carbapenemase gene located on a conjugative plasmid. Partial sequencing of 16S rDNA and rpoB genes, together with matrix-assisted laser desorption/ionisation time-of-flight (MALDI-TOF) analysis, showed that this strain was distantly related to the Acinetobacter baumannii-calcoaceticus complex and was closely related to A. indicus.

    In order to enhance sustainability, it is necessary to reduce the carbon intensity of human well-being (CIWB). In this paper, we analyze the impact of technology innovation and spillovers on CIWB using panel data of 30 provinces in China from 2005 to 2010. We find that increasing research and development (R&D) intensity and interregional R&D spillovers can decrease CIWB; R&D intensity has a nonlinear effect on CIWB without incorporating interregional R&D spillovers; economic development has positive effect on CIWB, while manufacturing has negative effect on CIWB.

    The promise of Big Biomedical Data may be offset by the enormous challenges in handling, analyzing, and sharing it. In this paper, we provide a framework for developing practical and reasonable data sharing policies that incorporate the sociological, financial, technical and scientific requirements of a sustainable Big Data dependent scientific community. Many biomedical and healthcare studies may be significantly impacted by using large, heterogeneous and incongruent datasets; however there are significant technical, social, regulatory, and institutional barriers that need to be overcome to ensure the power of Big Data overcomes these detrimental factors. Pragmatic policies that demand extensive sharing of data, promotion of data fusion, provenance, interoperability and balance security and protection of personal information are critical for the long term impact of translational Big Data analytics.

  18. Local Signaling Environments and Human Male Infertility: What Can Be Learned from Mouse Models

    Nalam, Roopa L.; Matzuk, Martin M.

    2011-01-01

    Infertility is one of the most prevalent public health problems facing young adult males in today’s society. A clear, treatable cause of infertility cannot be determined in a large number of these patients, and a growing body of evidence suggests that infertility in many of these men may be due to genetic causes. Studies utilizing animal models, and most importantly, mouse knockout technology, have been integral not only for the study of normal spermatogenesis but also for identifying proteins essential for this process, which in turn are candidate genes for causing human male infertility. Successful spermatogenesis depends on a delicate balance of local signaling factors, and this review focuses specifically on the genes that encode these factors. Normal functioning of all testicular cell types is not only essential for normal fertility but, as recently hypothesized, may also be crucial to prevent germ cell oncogenesis. Analysis of these processes using mouse models in vivo has provided investigators with an invaluable tool to effectively translate basic science research to the research of human disease and infertility.

    2014-01-01

    Full Text Available Focusing on the most impoverished populations, we critically review and synthesise key themes from dominant frameworks for assessing the relationship between well-being and ecosystem services in developing countries. This requires a differentiated approach to conceptualising well-being that appropriately reflects the perspectives of the poorest-those most directly dependent on ecosystem services, and their vulnerability to external and policy-driven environmental change. The frameworks analysed draw upon environmental sciences, economics, psychology, sociology, and anthropology, and were selected on the basis of their demonstrated or potential ability to illustrate the relationship between environmental change and human well-being, as well as their prevalence in real world applications. Thus, the synthesis offered here is informed by the various theoretical, methodological, and hermeneutical contributions from each field to the notion of well-being. The review highlights several key dimensions that should be considered by those interested in understanding and assessing the impact of environmental change on the well-being of the world′s poorest people: the importance of interdisciplinary consideration of well-being, the need for frameworks that integrate subjective and objective aspects of well-being, and the central importance of context and relational aspects of well-being. The review is of particular interest to those engaged in the post-2015 development agenda.

  20. Reservoirs and human well being: new challenges for evaluating impacts and benefits in the neotropics

    Directory of Open Access Journals (Sweden)

    JG. Tundisi

    Full Text Available As in many other continents, neotropical ecosystems are impacted by the construction of reservoirs. These artificial ecosystems change considerably the natural terrestrial and aquatic ecosystems and their biodiversity. The multiple uses of reservoirs promote benefits for the human beings in terms of economic development, income, jobs and employment. Services of reservoirs are important assets for the regional ecosystem. Evaluation of ecosystem services produced by artificial reservoirs, are new challenges to the understanding of the cost/benefit relationships of reservoir construction in the neotropics. Regulating and other services promoted by reservoirs lead to new trends for "green technology" and the implementation of ecohydrological and ecotechnological developments. This approach can be utilized with better success as a substitute for the usual impact/benefit evaluation of the reservoirs. Better and diversified services can be achieved with "green technology" applied to the construction.

    2008-01-01

    Pancreatic islet transplantation has demonstrated that long-term insulin independence may be achieved in patients suffering from diabetes mellitus type 1. However, limited availability of islet tissue means that new sources of insulinproducing cells that are responsive to glucose are required. Here, we show that human amnion epithelial cells (HAEC) can be induced to differentiate into functional insulinproducing cells in vitro. After induction of differentiation, HAEC expressed multiple pancreatic --cell genes, including insulin, pancreas duodenum homeobox-1, paired box gene 6,NK2 transcription factor-related locus 2, Islet 1, glucokinase,and glucose transporter-2, and released C-peptide in a glucose-regulated manner in response to other extracellular stimulations. The transplantation of induced HAEC into streptozotocin-induced diabetic C57 mice reversed hyperglycemia, restored body weight, and maintained euglycemia for 30 d. These findings indicated that HAEC may be a new source for cell replacement therapy in type 1 diabetes.

    The Ly-6 family of cell surface molecules includes many members that have been characterized in the mouse. Until recently, very few Ly-6 family members had been described in the human. A significant development with important implications for novel gene discovery has been the growth of the public Expressed Sequence Tag (EST) database. Here we report that, through the application of bioinformatics analysis to the dbEST database, we obtained the sequence of human TSA-1/SCA-2, a new member of the human Ly-6 family. In addition, we identified full-length clones encoding this molecule as well as expression data in various tissues. Sequencing of the clones identified this way confirmed the sequence predicted through bioinformatics. This study constitutes an example of the application of bioinformatics to the analysis of the recently expanded databases for the identification of genes of potential importance in the immune system.

    The global political economy is facing extreme challenges against a backdrop of large-scale expansion of human and domestic animal populations and related impacts on the biosphere. Significant global socio-ecological changes have occurred in the period of a single lifetime, driven by increased technology and access to physical and biological resources through open markets and globalization. Current resource consumption rates are not sustainable and ecological tipping points are being reached and one of the indicators of these may be a changing balance between hosts and pathogens. A period of extraordinary progress in reducing infection risk and disease impact on humans and domestic animals in the 20th Century is reversing in the 21st, but not always and not everywhere. Drivers for this shift are discussed in terms of demographics, agroecology, biodiversity decline and loss of resilience in ecosystems, climate change and increasing interconnectedness between species globally. Causality of disease emergence remains highly speculative, but patterns and data are emerging to commend a precautionary approach, while reassessing our global political, social and economic systems.

  8. Inequalities in Human Well-Being in the Urban Ganges Brahmaputra Meghna Delta

    2016-06-01

    Full Text Available The recently endorsed Sustainable Development Goals (SDGs agenda unanimously agrees on the need to focus on inclusive development, the importance of eradicating extreme poverty and managing often complex human well-being impacts of rapid urban growth. Sustainable and inclusive urbanisation will accelerate progress towards the SDGs and contribute to eradicating extreme poverty. In tropical delta regions, such as the Ganges Brahmaputra Meghna delta region, urban growth and resulting intra-urban inequalities are accelerated by the impact of environmental and climate change. In this context, the present study uses the 2010 Household Income and Expenditure Survey to analyse the extent of wealth-based inequalities in human well-being in the urban delta region and the determinants of selected welfare measures. The results suggest that the extent of intra-urban inequalities is greatest in educational attainment and access to postnatal healthcare and relatively low in the occurrence of gastric disease. The paper concludes by providing policy recommendations to reduce increasing wealth inequalities in urban areas, thus contributing to sustainable development of the region.

    Full Text Available Bone-marrow derived stem cells are multi potential or totipotent and are able to differentiate into numerous cell types. Their application is indicated in various reconstructive and restorative surgeries for rapid healing. A technique for creating cells that have the embryonic ability to turn into almost any cell type in the mammalian body has been reported. Recently, an unexpected phenomenon of somatic cell reprogramming into pluripotent cells by exposing to sublethal stimuli such as citrate based acidic medium has been reported. With the concept of creating acidic environment in chronic infected wounds to make a condition unsuitable for growth and multiplication of bacteria using 3% citric acid has been reported. It would be interesting to study whether the phenomenon of pluripotency takes place in chronic infected wounds in human beings following the application of 3% citric acid and plays an important role in formation of healthy granulation tissue.

  11. Current demographics suggest future energy supplies will be inadequate to slow human population growth.

    Directory of Open Access Journals (Sweden)

    John P DeLong

    Full Text Available Influential demographic projections suggest that the global human population will stabilize at about 9-10 billion people by mid-century. These projections rest on two fundamental assumptions. The first is that the energy needed to fuel development and the associated decline in fertility will keep pace with energy demand far into the future. The second is that the demographic transition is irreversible such that once countries start down the path to lower fertility they cannot reverse to higher fertility. Both of these assumptions are problematic and may have an effect on population projections. Here we examine these assumptions explicitly. Specifically, given the theoretical and empirical relation between energy-use and population growth rates, we ask how the availability of energy is likely to affect population growth through 2050. Using a cross-country data set, we show that human population growth rates are negatively related to per-capita energy consumption, with zero growth occurring at ∼13 kW, suggesting that the global human population will stop growing only if individuals have access to this amount of power. Further, we find that current projected future energy supply rates are far below the supply needed to fuel a global demographic transition to zero growth, suggesting that the predicted leveling-off of the global population by mid-century is unlikely to occur, in the absence of a transition to an alternative energy source. Direct consideration of the energetic constraints underlying the demographic transition results in a qualitatively different population projection than produced when the energetic constraints are ignored. We suggest that energetic constraints be incorporated into future population projections.

  13. Why Robots Should Be Social: Enhancing Machine Learning through Social Human-Robot Interaction.

    Directory of Open Access Journals (Sweden)

    Joachim de Greeff

    Full Text Available Social learning is a powerful method for cultural propagation of knowledge and skills relying on a complex interplay of learning strategies, social ecology and the human propensity for both learning and tutoring. Social learning has the potential to be an equally potent learning strategy for artificial systems and robots in specific. However, given the complexity and unstructured nature of social learning, implementing social machine learning proves to be a challenging problem. We study one particular aspect of social machine learning: that of offering social cues during the learning interaction. Specifically, we study whether people are sensitive to social cues offered by a learning robot, in a similar way to children's social bids for tutoring. We use a child-like social robot and a task in which the robot has to learn the meaning of words. For this a simple turn-based interaction is used, based on language games. Two conditions are tested: one in which the robot uses social means to invite a human teacher to provide information based on what the robot requires to fill gaps in its knowledge (i.e. expression of a learning preference; the other in which the robot does not provide social cues to communicate a learning preference. We observe that conveying a learning preference through the use of social cues results in better and faster learning by the robot. People also seem to form a "mental model" of the robot, tailoring the tutoring to the robot's performance as opposed to using simply random teaching. In addition, the social learning shows a clear gender effect with female participants being responsive to the robot's bids, while male teachers appear to be less receptive. This work shows how additional social cues in social machine learning can result in people offering better quality learning input to artificial systems, resulting in improved learning performance.

    A growing range of studies have begun to document the health and well-being benefits associated with contact with nature. Most studies rely on generalized self-reports following engagement in the natural environment. The actual in-situ experience during contact with nature, and the environmental features and factors that evoke health benefits have remained relatively unexplored. Smartphones offer a new opportunity to monitor and interact with human subjects during everyday life using techniques such as Experience Sampling Methods (ESM) that involve repeated self-reports of experiences as they occur in-situ. Additionally, embedded sensors in smartphones such as Global Positioning Systems (GPS) and accelerometers can accurately trace human activities. This paper explores how these techniques can be combined to comprehensively explore the perceived health and well-being impacts of contact with nature. Custom software was developed to passively track GPS and accelerometer data, and actively prompt subjects to complete an ESM survey at regular intervals throughout their visit to a provincial park in Ontario, Canada. The ESM survey includes nine scale questions concerning moods and emotions, followed by a series of open-ended experiential questions that subjects provide recorded audio responses to. Pilot test results are used to illustrate the nature, quantity and quality of data obtained. Participant activities were clearly evident from GPS maps, including especially walking, cycling and sedate activities. From the ESM surveys, participants reported an average of 25 words per question, taking an average of 15 s to record them. Further qualitative analysis revealed that participants were willing to provide considerable insights into their experiences and perceived health impacts. The combination of passive and interactive techniques is sure to make larger studies of this type more affordable and less burdensome in the future, further enhancing the ability to understand

    Defects involving specialised areas with characteristic anatomical features, such as the nipple, upper eyelid, and lip, benefit greatly from the use of sharing procedures. The vulva, a complex 3-dimensional structure, can also be reconstructed through a sharing procedure drawing upon the contralateral vulva. In this report, we present the interesting case of a patient with chronic, massive, localised lymphedema of her left labia majora that was resected in 2011. Five years later, she presented with squamous cell carcinoma over the left vulva region, which is rarely associated with chronic lymphedema. To the best of our knowledge, our management of the radical vulvectomy defect with a labia majora sharing procedure is novel and has not been previously described. The labia major flap presented in this report is a shared flap; that is, a transposition flap based on the dorsal clitoral artery, which has consistent vascular anatomy, making this flap durable and reliable. This procedure epitomises the principle of replacing like with like, does not interfere with leg movement or patient positioning, has minimal donor site morbidity, and preserves other locoregional flap options for future reconstruction. One limitation is the need for a lax contralateral vulva. This labia majora sharing procedure is a viable option in carefully selected patients. PMID:28194353

    By 2050, 70% of the world's population will live in urban areas. In many cases urbanization reduces the richness and abundance of native species. Living in highly modified environments with fewer opportunities to interact directly with a diversity of native species may adversely affect residents' personal well-being and emotional connection to nature. We assessed the personal well-being, neighborhood well-being (a measure of a person's satisfaction with their neighborhood), and level of connection to nature of over 1000 residents in 36 residential neighborhoods in southeastern Australia. We modeled these response variables as a function of natural features of each neighborhood (e.g., species richness and abundance of birds, density of plants, and amount of vegetation cover) and demographic characteristics of surveyed residents. Vegetation cover had the strongest positive relations with personal well-being, whereas residents' level of connection to nature was weakly related to variation in species richness and abundance of birds and density of plants. Demographic characteristics such as age and level of activity explained the greatest proportion of variance in well-being and connection to nature. Nevertheless, when controlling for variation in demographic characteristics (examples were provided above), neighborhood well-being was positively related to a range of natural features, including species richness and abundance of birds, and vegetation cover. Demographic characteristics and how well-being was quantified strongly influenced our results, and we suggest demography and metrics of well-being must be considered when attempting to determine relations between the urban environment and human well-being. © 2011 Society for Conservation Biology.

  20. Time, human being and mental health care: an introduction to Gilles Deleuze.

    The French philosopher, Gilles Deleuze, is emerging as one of the most important and influential philosophers of the 20th century, having published widely on philosophy, literature, language, psychoanalysis, art, politics, and cinema. However, because of the 'experimental' nature of certain works, combined with the manner in which he draws upon a variety of sources from various disciplines, his work can seem difficult, obscure, and even 'willfully obstructive'. In an attempt to resist such impressions, this paper will seek to provide an accessible introduction to Deleuze's work, and to begin to discuss how it can be employed to provide a significant critique and reconceptualization of the theoretical foundations and therapeutic practices of psychiatry, psychotherapy, and mental health nursing. In order to do this, the paper will focus upon Deleuze's masterwork, and the cornerstone to his philosophy as a whole, Difference and Repetition; in particular, it will discuss how his innovative and challenging account of time can be employed to provide a conception of human life as a 'continuity', rather than as a series of distinct 'moments' or 'events'. As well as discussing the manner in which his work can provide us with an understanding of how life is different and significant for each human being, this paper will also highlight the potential importance of Deleuze's work for logotherapy, for the recent 'turn' to 'narrative' as a psychotherapeutic approach and for contemporary mental health care's growing interest in 'social constructionism'. As such, this paper also seeks to stimulate further discussion and research into the importance and the relevance of Deleuze's work for the theory and practice of psychiatry, psychotherapy, and mental health nursing.

    Full Text Available Abstract Background Neogenin is expressed in cap cells that have been suggested to be mammary stem or precursor cells. Neogenin is known to play an important role in mammary morphogenesis; however its relationship to tumorigenesis remains to be elucidated. Methods To compare the expression levels of neogenin in cells with different tumorigenicity, the expression levels in M13SV1, M13SV1R2 and M13SV1R2N1 cells, which are immortalized derivatives of type I human breast epithelial cells, were evaluated. Then we measured the expression level of neogenin in paired normal and cancer tissues from eight breast cancer patients. Tissue array analysis was performed for 54 human breast tissue samples with different histology, and the results were divided into four categories (none, weak, moderate, strong by a single well-trained blinded pathologist and statistically analyzed. Results The nontumorigenic M13SV1 cells and normal tissues showed stronger expression of neogenin than the M13SV1R2N1 cells and the paired cancer tissues. In the tissue array, all (8/8 of the normal breast tissues showed strong neogenin expression, while 93.5% (43/46 of breast cancer tissues had either no expression or only moderate levels of neogenin expression. There was a significant difference, in the expression level of neogenin, in comparisons between normal and infiltrating ductal carcinoma (p Conclusion Neogenin may play a role in mammary carcinogenesis as well as morphogenesis, and the expression may be inversely correlated with mammary carcinogenicity. The value of neogenin as a potential prognostic factor needs further evaluation.

    Objective Shared epitope (SE)-coding DRB1 alleles are associated with bone erosion in several diseases, including rheumatoid arthritis (RA) and periodontal disease (PD), but the underlying mechanism is unknown. We have recently identified the SE as an osteoclast-activating ligand. To better understand the biological effects of the SE in vivo, here we sought to determine whether it can facilitate spontaneous bone damage in naïve mice. Methods 3-month old naïve transgenic mice that carry the human SE-coding allele DRB1*04:01, or a SE-negative allele DRB1*04:02 were studied. Bone tissues were analysed by micro-CT, and the tooth-supporting tissues were studied by histology, immunohistochemistry and immunofluorescence. Serum biomarkers were determined by ELISA. Results Transgenic mice expressing the SE-coding DRB1*04:01 allele, but not mice carrying the SE-negative allele DRB1*04:02, showed spontaneous PD associated with interleukin (IL)-17 overabundance and periostin disruption. Mandibular bone volumetric and mineralisation parameters were significantly lower in SE-positive mice, and alveolar bone resorption was significantly increased in these mice. SE-positive mice also had more slender tibiae, and their marrow, cortical and total areas were lower than those of SE-negative mice. Additionally, significantly increased serum IL-17, tumour necrosis factor-α and osteoprotegrin levels were found in SE-positive mice, while their receptor activator of nuclear factor κ-B ligand levels were significantly lower. Conclusions A human SE-coding allele increases the propensity to spontaneous bone-destructive periodontal inflammation and skeletal bone damage in transgenic mice. These findings provide new insights into the previously documented but poorly understood association of the SE with accelerated bone erosion in RA and several other human diseases. PMID:27933212

    The ability to communicate with others is one of the most important human social functions, yet communication is not always investigated from a social perspective. This research examined the role that shared social identity plays in communication effectiveness using a minimal group paradigm. In two experiments, participants constructed a model using instructions that were said to be created by an ingroup or an outgroup member. Participants made models of objectively better quality when working from communications ostensibly created by an ingroup member (Experiments 1 and 2). However, this effect was attenuated when participants were made aware of a shared superordinate identity that included both the ingroup and the outgroup (Experiment 2). These findings point to the importance of shared social identity for effective communication and provide novel insights into the social psychology of communication. © 2014 by the Society for Personality and Social Psychology, Inc.

    What would be the "terrible loneliness" and what would be the "wonderful agreement" in the present paper? The "terrible loneliness" is the only reality that a person perceives and/or thinks during the now going on. For the person, an enormous quantity of occurrences is in the present moment absent. A very small quantity of occurrences is present. The person is the only being in having this. And, this is only during a little moment. The person never thinks about his loneliness in this moment. On the contrary, he thinks he is plenty of people and full of occurrences. But, if he were thinking about reality, he would live in a terrible loneliness. How does he escape himself from this loneliness? He thinks that the probable occurrences are real occurrences. He may be right in a plenty of times. Going through what I call opening hypotheses--basic hypotheses and non-basic but important hypotheses--and going through what I call simply hypotheses he is able to sanction a wonderful agreement of human beings about the known parts of the Universe. However, they are hypotheses, not absolute realities.

    Research suggests that having a sexually transmitted infection (STI) such as genital herpes and human papillomavirus (HPV) can negatively affect sexual well-being. However, there is little research examining factors associated with poorer sexual well-being among individuals with a STI. This study investigated the extent to which stigma experiences, individual characteristics, and STI characteristics were associated with multiple aspects of sexual well-being among individuals diagnosed with herpes and/or HPV. Participants were an average of 36 years old (SD = 11.58) and included 188 individuals with herpes and/or HPV who completed measures of sexual activity, sexual problems, and sexual cognitive-affective factors. The results showed that experiences of stigmatization were the most important predictors of sexual well-being. Participants who perceived were stigmatized by others as well as those who internalized negative social attitudes to a greater extent reported poorer sexual well-being across all dimensions, over and above individual and STI characteristics. The implications of these findings for sexual health professionals are discussed.

    Conservationists are increasingly engaging with the concept of human well-being to improve the design and evaluation of their interventions. Since the convening of the influential Sarkozy Commission in 2009, development researchers have been refining conceptualizations and frameworks to understand and measure human well-being and are starting to converge on a common understanding of how best to do this. In conservation, the term human well-being is in widespread use, but there is a need for guidance on operationalizing it to measure the impacts of conservation interventions on people. We present a framework for understanding human well-being, which could be particularly useful in conservation. The framework includes 3 conditions; meeting needs, pursuing goals, and experiencing a satisfactory quality of life. We outline some of the complexities involved in evaluating the well-being effects of conservation interventions, with the understanding that well-being varies between people and over time and with the priorities of the evaluator. Key challenges for research into the well-being impacts of conservation interventions include the need to build up a collection of case studies so as to draw out generalizable lessons; harness the potential of modern technology to support well-being research; and contextualize evaluations of conservation impacts on well-being spatially and temporally within the wider landscape of social change. Pathways through the smog of confusion around the term well-being exist, and existing frameworks such as the Well-being in Developing Countries approach can help conservationists negotiate the challenges of operationalizing the concept. Conservationists have the opportunity to benefit from the recent flurry of research in the development field so as to carry out more nuanced and locally relevant evaluations of the effects of their interventions on human well-being.

    Human embryonic stem cells have shown tremendous potential in regenerative medicine, and the recent progress in haploid embryonic stem cells provides new insights for future applications of embryonic stem cells. Disruption of normal fertilized embryos remains controversial; thus, the development of a new source for human embryonic stem cells is important for their usefulness. Here, we investigated the feasibility of haploid and diploid embryo reconstruction and embryonic stem cell derivation using microsurgically repaired tripronuclear human zygotes. Diploid and haploid zygotes were successfully reconstructed, but a large proportion of them still had a tripolar spindle assembly. The reconstructed embryos developed to the blastocyst stage, although the loss of chromosomes was observed in these zygotes. Finally, triploid and diploid human embryonic stem cells were derived from tripronuclear and reconstructed zygotes (from which only one pronucleus was removed), but haploid human embryonic stem cells were not successfully derived from the reconstructed zygotes when two pronuclei were removed. Both triploid and diploid human embryonic stem cells showed the general characteristics of human embryonic stem cells. These results indicate that the lower embryo quality resulting from abnormal spindle assembly contributed to the failure of the haploid embryonic stem cell derivation. However, the successful derivation of diploid embryonic stem cells demonstrated that microsurgical tripronuclear zygotes are an alternative source of human embryonic stem cells. In the future, improving spindle assembly will facilitate the application of triploid zygotes to the field of haploid embryonic stem cells.

  8. β-Cell Generation: Can Rodent Studies Be Translated to Humans?

    Full Text Available β-cell replacement by allogeneic islet transplantation is a promising approach for patients with type 1 diabetes, but the shortage of organ donors requires new sources of β cells. Islet regeneration in vivo and generation of β-cells ex vivo followed by transplantation represent attractive therapeutic alternatives to restore the β-cell mass. In this paper, we discuss different postnatal cell types that have been envisaged as potential sources for future β-cell replacement therapy. The ultimate goal being translation to the clinic, a particular attention is given to the discrepancies between findings from studies performed in rodents (both ex vivo on primary cells and in vivo on animal models, when compared with clinical data and studies performed on human cells.

    A specialized isotope mass spectrometer for noninvasive diagnostics of Helicobacter pylori infection in human beings based on the carbon-13 isotope breath test has been designed and constructed. Important stages of the work included (i) calculating a low-aberration mass analyzer, (ii) manufacturing and testing special gas inlet system, and (iii) creating a small-size collector of ions. The proposed instrument ensures 13C/12C isotopic ratio measurement to within 1.7‰ (pro mille) accuracy, which corresponds to requirements for a diagnostic tool. Preliminary medical testing showed that the mass spectrometer is applicable to practical diagnostics. The instrument is also capable of measuring isotopic ratios of other light elements, including N, O, B (for BF2+ ions), Ar, Cl, and S.

    Review of the principal physiological changes seen in space flight, and discussion of various countermeasures which may prove to be useful in combating these changes in long-term space flight. A number of transient changes seen in Apollo astronauts following space flights are discussed, including cardiovascular and hemodynamic responses to weightlessness, musculoskeletal changes, changes in fluid and electrolyte balance, microbiological changes, and vestibular effects. A number of countermeasures to the effects of space flight on man are cited, including exercise, medication, diet, lower-body negative pressure, gradient positive pressure, venous occlusion cuffs, and others. A detailed review is then made of a number of psychological factors bearing on the ability of the human organism to withstand the rigors of long space flights.

    Since their origin, human populations have colonized the whole planet, but the demographic processes governing range expansions are mostly unknown. We analyzed the genealogy of more than one million individuals resulting from a range expansion in Quebec between 1686 and 1960 and reconstructed the spatial dynamics of the expansion. We find that a majority of the present Saguenay Lac-Saint-Jean population can be traced back to ancestors having lived directly on or close to the wave front. Ancestors located on the front contributed significantly more to the current gene pool than those from the range core, likely due to a 20% larger effective fertility of women on the wave front. This fitness component is heritable on the wave front and not in the core, implying that this life-history trait evolves during range expansions.

    Intravenous infusion of fructose has been shown to enhance reduced form of nicotinamide adenine dinucleotide reoxidation and, thereby, to enhance the metabolism of ethanol. In the current study, the effect of fructose infusion on first-pass metabolism of ethanol was studied in human volunteers....... A significantly higher first-pass metabolism of ethanol was obtained after administration of fructose in comparison with findings for control experiments with an equimolar dose of glucose. Because fructose is metabolized predominantly in the liver and can be presumed to have virtually no effects in the stomach......, results of the current study support the assumption that only a negligible part of first-pass metabolism of ethanol occurs in the stomach....

    Full Text Available Over 60,500 dengue cases were reported in the state of Espírito Santo (ES, Brazil, between 1995 and 1998. The study's purpose was to identify whether Aedes albopictus was transmitting the dengue virus during an epidemic in the locality of Vila Bethânia (Viana County,Vitória, ES. From April 3 to 9, 1998, blood and serum samples were collected daily for virus isolation and serological testing. Four autochthonous cases were confirmed through DEN 1 virus isolation and two autochthonous cases through MAC ELISA testing. Of 37 Ae. aegypti and 200 Ae. albopictus adult mosquitoes collected and inoculated, DEN1 virus was isolated only from a pool of two Ae. aegypti female mosquitoes. The study results suggest that Ae. albopictus still cannot be considered an inter-human vector in dengue epidemics in Brazil.

    2015-10-01

    Full Text Available Fecal microbiota transplantation (FMT has emerged as a highly effective treatment for Clostridium difficile infection (CDI, the most frequent cause of hospital-acquired infectious diarrhea in developed countries and the cause of nearly 30,000 annual deaths in the US. FMT is proving to be more effective at treating CDI than traditional antibacterial therapy, and reduces the exposure of valuable antibiotics to potential resistance. A systematic review to assess the efficacy of FMT for CDI treatment showed that across all studies for recurrent CDI, symptom resolution was observed in 85% of patients. The United States Food and Drug Administration currently classifies FMT as an investigational drug, which imparts overly restrictive regulations that are impossible to apply to FMT in the same manner as conventional drugs. Reclassification of FMT to a human cell, tissue, and cellular and tissue-based product could potentially expand access to this important treatment while maintaining rigorous safety standards.

    When then president José Figueres Ferrer invited the world to use Costa Rica as a "laboratory for sustainable development" in 1997, the country's fame as a biodiversity mecca was firmly established. Yet despite vast investment, conservation-related interventions in the cantons of Osa and Golfito along the country's southern Pacific coast have been seen as overly conservation-oriented and carried out "with its back to the communities." By ignoring human well-being, these interventions have been unable to overcome the region's vast disparities in access to resources and general state of underdevelopment despite investments of many millions of dollars in recent decades. With the country's third international airport and Central America's largest hydroelectric project proposed for the region, as well as other infrastructure-driven development currently underway, the region is poised to undergo rapid change. This presentation first describes the Osa-Golfito Initiative (INOGO), an interdisciplinary effort facilitated by the Stanford Woods Institute for the Environment to development a long term strategic action plan that ensures a development trajectory focused on human and environmental well-being. Whereas a concurrent presentation will focus on biophysical components of INOGO, the focus here is on the often-overlooked contributions of social science for ensuring the region's future sustainability. An anthropological approach is taken to assess the assets and resources of the region's residents, and the obstacles and challenges as they perceive them. This groundwork provides a crucial link between individual and local realities, and the regional and national political economy, and thus provides greater probability of sustainable development occurring with its "face to the communities.";

    Data sharing is essential for a better understanding of genetic disorders. Good phenotype coding plays a key role in this process. Unfortunately, the two most widely used coding systems in medicine, ICD-10 and SNOMED-CT, lack information necessary for the detailed classification and annotation of rare and genetic disorders. This prevents the optimal registration of such patients in databases and thus data-sharing efforts. To improve care and to facilitate research for patients with metabolic disorders, we developed a new coding system for metabolic diseases with a dedicated group of clinical specialists. Next, we compared the resulting codes with those in ICD and SNOMED-CT. No matches were found in 76% of cases in ICD-10 and in 54% in SNOMED-CT. We conclude that there are sizable gaps in the SNOMED-CT and ICD coding systems for metabolic disorders. There may be similar gaps for other classes of rare and genetic disorders. We have demonstrated that expert groups can help in addressing such coding issues. Our coding system has been made available to the ICD and SNOMED-CT organizations as well as to the Orphanet and HPO organizations for further public application and updates will be published online (www.ddrmd.nl and www.cineas.org).

    Current ground robots are largely employed via tele-operation and provide their operators with useful tools to extend reach, improve sensing, and avoid dangers. To move from robots that are useful as tools to truly synergistic human-robot teaming, however, will require not only greater technical capabilities among robots, but also a better understanding of the ways in which the principles of teamwork can be applied from exclusively human teams to mixed teams of humans and robots. In this respect, a core characteristic that enables successful human teams to coordinate shared tasks is their ability to create, maintain, and act on a shared understanding of the world and the roles of the team and its members in it. The team performance literature clearly points towards two important cornerstones for shared understanding of team members: mental models and situation awareness. These constructs have been investigated as products of teams as well; amongst teams, they are shared mental models and shared situation awareness. Consequently, we are studying how these two constructs can be measured and instantiated in human-robot teams. In this paper, we report results from three related efforts that are investigating process and performance outcomes for human robot teams. Our investigations include: (a) how human mental models of tasks and teams change whether a teammate is human, a service animal, or an advanced automated system; (b) how computer modeling can lead to mental models being instantiated and used in robots; (c) how we can simulate the interactions between human and future robotic teammates on the basis of changes in shared mental models and situation assessment.

    Humans make both random and systematic errors when reproducing learned movements. Intuitive haptic guidance that assists one to make the movements reduces such errors. Our study examined whether any additional haptic information about the location of the target reduces errors in a position reproduction task, or whether the haptic guidance needs to be assistive to do so. Holding a haptic device, subjects made reaches to visible targets without time constraints. They did so in a no-guidance condition, and in guidance conditions in which the direction of the force with respect to the target differed, but the force scaled with the distance to the target in the same way. We examined whether guidance forces directed towards the target would reduce subjects’ errors in reproducing a prior position to the same extent as do forces rotated by 90 degrees or 180 degrees, as it might because the forces provide the same information in all three cases. Without vision of the arm, both the accuracy and precision were significantly better with guidance directed towards the target than in all other conditions. The errors with rotated guidance did not differ from those without guidance. Not surprisingly, the movements tended to be faster when guidance forces directed the reaches to the target. This study shows that haptic guidance significantly improved motor performance when using it was intuitive, while non-intuitively presented information did not lead to any improvements and seemed to be ignored even in our simple paradigm with static targets and no time constraints.

    Full Text Available Toxoplasmosis is one of the biggest wild world zoonosis and it can attack blood warmed animals from many species. Outbreaks of toxoplasmosis in humans and animals are not related frequently and it could be due to either weak or asymptomatic characteristics. So, there are difficulties in the clinical characterization of this pathology with laboratorial confirmation and posterior notification.

    The problems of the haves differ substantially from those of the have-nots. Individuals in developing societies have to fight mainly against infectious and communicable diseases, while in the developed world the battles are mainly against lifestyle diseases. Yet, at a very fundamental level, the problems are the same-the fight is against distress, disability, and premature death; against human exploitation and for human development and self-actualisation; against the callousness to critical concerns in regimes and scientific power centres. While there has been great progress in the treatment of individual diseases, human pathology continues to increase. Sicknesses are not decreasing in number, they are only changing in type. The primary diseases of poverty like TB, malaria, and HIV/AIDS-and the often co-morbid and ubiquitous malnutrition-take their toll on helpless populations in developing countries. Poverty is not just income deprivation but capability deprivation and optimism deprivation as well. While life expectancy may have increased in the haves, and infant and maternal mortality reduced, these gains have not necessarily ensured that well-being results. There are ever-multiplying numbers of individuals whose well-being is compromised due to lifestyle diseases. These diseases are the result of faulty lifestyles and the consequent crippling stress. But it serves no one's purpose to understand them as such. So, the prescription pad continues to prevail over lifestyle-change counselling or research. The struggle to achieve well-being and positive health, to ensure longevity, to combat lifestyle stress and professional burnout, and to reduce psychosomatic ailments continues unabated, with hardly an end in sight. We thus realise that morbidity, disability, and death assail all three societies: the ones with infectious diseases, the ones with diseases of poverty, and the ones with lifestyle diseases.

  5. Data sharing in neuroimaging research

    Full Text Available Significant resources around the world have been invested in neuroimaging studies of brain function and disease. Easier access to this large body of work should have profound impact on research in cognitive neuroscience and psychiatry, leading to advances in the diagnosis and treatment of psychiatric and neurological disease. A trend toward increased sharing of neuroimaging data has emerged in recent years. Nevertheless, a number of barriers continue to impede momentum. Many researchers and institutions remain uncertain about how to share data or lack the tools and expertise to participate in data sharing. The use of electronic data capture methods for neuroimaging greatly simplifies the task of data collection and has the potential to help standardize many aspects of data sharing. We review here the motivations for sharing neuroimaging data, the current data sharing landscape, and the sociological or technical barriers that still need to be addressed. The INCF Task Force on Neuroimaging Datasharing, in conjunction with several collaborative groups around the world, has started work on several tools to ease and eventually automate the practice of data sharing. It is hoped that such tools will allow researchers to easily share raw, processed, and derived neuroimaging data, with appropriate metadata and provenance records, and will improve the reproducibility of neuroimaging studies. By providing seamless integration of data sharing and analysis tools within a commodity research environment, the Task Force seeks to identify and minimize barriers to data sharing in the field of neuroimaging.

  6. Experience sharing, emotional reciprocity, and turn-taking

    Full Text Available In this perspective article, we consider the relationship between experience sharing and turn-taking. There is much evidence suggesting that human social interaction is permeated by two temporal organizations: (1 the sequential framework of turn-taking and (2 the concurrent framework of emotional reciprocity. From this perspective, we introduce two alternative hypotheses about how the relationship between experience sharing and turn-taking could be viewed. According to the first hypothesis, the home environment of experience sharing is in the concurrent framework of emotional reciprocity, while the motivation to share experiences is in tension with the sequential framework of turn-taking. According to the second hypothesis, then again, people’s inclination to coordinate their actions in terms of turn-taking is motivated precisely by their propensity to share experiences. We consider theoretical and empirical ideas in favor of both of these hypotheses and discuss their implications for future research.

    As society strives to transition towards more sustainable development pathways, it is important to properly conceptualize the link between biodiversity (i.e. genes, traits, species and other dimensions) and human well-being (HWB; i.e. health, wealth, security and other dimensions). Here, we explore how published conceptual frameworks consider the extent to which the biodiversity–HWB links are being integrated into public discourse and scientific research and the implications of our findings for sustainable development. We find that our understanding has gradually evolved from seeing the value of biodiversity as an external commodity that may influence HWB to biodiversity as fundamental to HWB. Analysis of the literature trends indicates increasing engagement with the terms biodiversity, HWB and sustainable development in the public, science and policy spheres, but largely as independent rather than linked terms. We suggest that a consensus framework for sustainable development should include biodiversity explicitly as a suite of internal variables that both influence and are influenced by HWB. Doing so will enhance clarity and help shape coherent research and policy priorities. We further suggest that the absence of this link in development can inadvertently lead to a ratcheting down of biodiversity by otherwise well-meaning policies. Such biotic impoverishment could lock HWB at minimum levels or lead to its decline and halt or reverse progress in achieving sustainable development. PMID:27928039

    One of society's greatest challenges is to sustain natural resources while promoting economic growth and quality of life. In the face of this challenge, society must measure the effectiveness of programs established to safeguard the environment. The impetus for demonstrating positive results from government-sponsored research and regulation in the United States comes from Congress (General Accountability Office; GAO) and the Executive Branch (Office of Management and Budget; OMB). The message is: regulatory and research programs must demonstrate outcomes that justify their costs. Although the concept is simple, it is a complex problem to demonstrate that environmental research, policies, and regulations cause measurable changes in environmental quality. Even where changes in environmental quality can be tracked reliably, the connections between government actions and environmental outcomes seldom are direct or straightforward. In this article, we describe emerging efforts (with emphasis on the role of the U.S. Environmental Protection Agency; EPA) to frame and measure environmental outcomes in terms of ecosystem services and values-societally and ecologically meaningful metrics for gauging how well we manage environmental resources. As examples of accounting for outcomes and values, we present a novel, low-cost method for determining relative values of multiple ecosystem services, and describe emerging research on indicators of human well-being.

  9. TSPO PIGA Ligands Promote Neurosteroidogenesis and Human Astrocyte Well-Being

    2016-06-01

    Full Text Available The steroidogenic 18 kDa translocator protein (TSPO is an emerging, attractive therapeutic tool for several pathological conditions of the nervous system. Here, 13 high affinity TSPO ligands belonging to our previously described N,N-dialkyl-2-phenylindol-3-ylglyoxylamide (PIGA class were evaluated for their potential ability to affect the cellular Oxidative Metabolism Activity/Proliferation index, which is used as a measure of astrocyte well-being. The most active PIGA ligands were also assessed for steroidogenic activity in terms of pregnenolone production, and the values were related to the metabolic index in rat and human models. The results showed a positive correlation between the increase in the Oxidative Metabolism Activity/Proliferation index and the pharmacologically induced stimulation of steroidogenesis. The specific involvement of steroid molecules in mediating the metabolic effects of the PIGA ligands was demonstrated using aminoglutethimide, a specific inhibitor of the first step of steroid biosynthesis. The most promising steroidogenic PIGA ligands were the 2-naphthyl derivatives that showed a long residence time to the target, in agreement with our previous data. In conclusion, TSPO ligand-induced neurosteroidogenesis was involved in astrocyte well-being.

    Full Text Available Seasonal behaviour of human diseases have been observed and reported in the literature for years. Although the Sun plays an essential role in the origin and evolution of life on Earth, it is barely taken into account in biological processes for the development of a specific disease. Higher mortality rates occur during the winter season in the Northern Hemisphere for several diseases, particularly diseases of the cardiovascular and respiratory systems. This increment has been associated with seasonal and social causes. However, is there more behind these correlations, in particular in terms of solar variability? In this paper we attempt to make a first step towards answering this question. A detailed wavelet analysis of periodicities for diseases from England and Wales seem to reveal that mortality periodicities (3 days to half a year could be due to the Earth's position around the Sun. Moreover, crosswavelet and wavelet coherence analysis show common features between medical diseases and solar proxies around solar maximum activity suggesting that this relation, if any, has to be searched in times of high solar activity.

    Escherichia coli is the most common cause of urinary tract infection (UTI). Phylogroup B2 and D isolates are associated with UTI. It has been proposed that E. coli causing UTI could have an animal origin. The objective of this study was to investigate the phylogroups and antimicrobial resistance, and their possible associations in E. coli isolates from patients with UTI, community-dwelling humans, broiler chicken meat, broiler chickens, pork, and pigs in Denmark. A total of 964 geographically and temporally matched E. coli isolates from UTI patients (n = 102), community-dwelling humans (n = 109), Danish (n = 197) and imported broiler chicken meat (n = 86), Danish broiler chickens (n = 138), Danish (n = 177) and imported pork (n = 10), and Danish pigs (n = 145) were tested for phylogroups (A, B1, B2, D, and nontypeable [NT] isolates) and antimicrobial susceptibility. Phylogroup A, B1, B2, D, and NT isolates were detected among all groups of isolates except for imported pork isolates. Antimicrobial resistance to three (for B2 isolates) or five antimicrobial agents (for A, B1, D, and NT isolates) was shared among isolates regardless of origin. Using cluster analysis to investigate antimicrobial resistance data, we found that UTI isolates always grouped with isolates from meat and/or animals. We detected B2 and D isolates, that are associated to UTI, among isolates from broiler chicken meat, broiler chickens, pork, and pigs. Although B2 isolates were found in low prevalences in animals and meat, these sources could still pose a risk for acquiring uropathogenic E. coli. Further, E. coli from animals and meat were very similar to UTI isolates with respect to their antimicrobial resistance phenotype. Thus, our study provides support for the hypothesis that a food animal and meat reservoir might exist for UTI-causing E. coli.

  18. Food Sharing among Hadza Hunter-Gatherer Children.

    Directory of Open Access Journals (Sweden)

    Alyssa N Crittenden

    Full Text Available Human prosociality is one of the defining characteristics of our species, yet the ontogeny of altruistic behavior remains poorly understood. The evolution of widespread food sharing in humans helped shape cooperation, family formation, life history, language, and the development of economies of scale. While the behavioral and ecological correlates of food sharing among adults are widely studied, very little is known about food sharing among children. Here, in the first study to analyze the food sharing patterns of hunter-gatherer children, we show that while sharing may be biased towards kin, reciprocity characterizes the majority of all sharing dyads, both related and unrelated. These data lend support to the recent claim that discrimination among kin might be linked with reciprocal altruism theory. Furthermore, we show that age positively correlates with an increase in sharing, both in frequency and amount, supporting recent suggestions that prosocial behaviors and egalitarianism develop strongly in middle childhood when children acquire the normative rules of their society.

    To date, marginal, asymptomatic biotin deficiency has been successfully induced experimentally by the use of labor-intensive inpatient designs requiring rigorous dietary control. We sought to determine if marginal biotin deficiency could be induced in humans in a less expensive outpatient design incorporating a self-selected, mixed general diet. We sought to examine the efficacy of three outpatient study designs: two based on oral avidin dosing and one based on a diet high in undenatured egg white for a period of 28 d. In study design 1, participants (n = 4; 3 women) received avidin in capsules with a biotin binding capacity of 7 times the estimated dietary biotin intake of a typical self-selected diet. In study design 2, participants (n = 2; 2 women) received double the amount of avidin capsules (14 times the estimated dietary biotin intake). In study design 3, participants (n = 5; 3 women) consumed egg-white beverages containing avidin with a biotin binding capacity of 7 times the estimated dietary biotin intake. Established indices of biotin status [lymphocyte propionyl-CoA carboxylase activity; urinary excretion of 3-hydroxyisovaleric acid, 3-hydroxyisovaleryl carnitine (3HIA-carnitine), and biotin; and plasma concentration of 3HIA-carnitine] indicated that study designs 1 and 2 were not effective in inducing marginal biotin deficiency, but study design 3 was as effective as previous inpatient study designs that induced deficiency by egg-white beverage. Marginal biotin deficiency can be induced experimentally by using a cost-effective outpatient design by avidin delivery in egg-white beverages. This design should be useful to the broader nutritional research community.

  20. Why human evolution should be a basic science for medicine and psychology students.

    Palanza, Paola; Parmigiani, Stefano

    2016-06-20

    Based on our teaching experience in medicine and psychology degree programs, we examine different aspects of human evolution that can help students to understand how the human body and mind work and why they are vulnerable to certain diseases. Three main issues are discussed: 1) the necessity to consider not only the mechanisms, i.e. the "proximate causations", implicated in biological processes but also why these mechanisms have evolved, i.e. the "ultimate causations" or "adaptive significance", to understand the functioning and malfunctioning of human body and mind; 2) examples of how human vulnerabilities to disease are caused by phylogenetic constraints, evolutionary tradeoffs reflecting the combined actions of natural and sexual selection, and/or mismatch between past and present environment (i.e., evolution of the eye, teeth and diets, erect posture and their consequences); 3) human pair-bonding and parent-offspring relationships as the result of socio-sexual selection and evolutionary compromises between cooperation and conflict. These psychobiological mechanisms are interwoven with our brain developmental plasticity and the effects of culture in shaping our behavior and mind, and allow a better understanding of functional (normal) and dysfunctional (pathological) behaviors. Thus, because the study of human evolution offers a powerful framework for clinical practice and research, the curriculum studiorum of medical and psychology students should include evolutionary biology and human phylogeny.

    Descriptions of the epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) have seldom been produced in the Caribbean, which is a major tourism destination. Using DNA microarrays and spa typing, we characterized 85 MRSA isolates from human skin and soft-tissue infections from five different islands. In the French West Indies (n = 72), the most frequently isolated clones were the same clones that are specifically isolated from mainland France [Lyon (n = 35) and Geraldine (n = 11) clones], whereas the clones that were most frequently isolated from the other islands (n = 13) corresponded with clones that have a worldwide endemic spread [Vienna/Hungarian/Brazilian (n = 5), Panton Valentine leukocidin-positive USA300 (n = 4), New York/Japan (n = 2), and pediatric (n = 1) clones]. The distribution of the major MRSA clones in the French (Guadeloupe and Martinique) and non-French West Indies (Jamaica, Trinidad, and Tobago) is different, and the clones most closely resemble those found in the home countries of the travelers who visit the islands most frequently. The distribution might be affected by tourist migration, which is specific to each island. © 2013 International Society of Travel Medicine.

    2015-07-15

    Cytological screening has substantially decreased the cervical cancer incidence, but even better protection may be achieved by primary high-risk human papillomavirus (hrHPV) screening. In the Netherlands, five-yearly cytological screening for women aged 30-60 years will be replaced by primary hrHPV screening in 2016. The new screening guidelines involve an extension of the screening interval from 5 to 10 years for hrHPV-negative women aged 40 or 50 years. We investigated the impact of this program change on the lifetime cancer risks in women without an hrHPV infection at age 30, 35, 40, 45 or 50 years. The time to cancer was estimated using 14-year follow-up data from a population-based screening intervention trial and the nationwide database of histopathology reports. The new screening guidelines are expected to lead to a reduced cervical cancer risk for all age groups. The average risk reduction was 34% and was smallest (25%) among women aged 35 years. The impact of hrHPV screening on the cancer risk was sensitive to the duration from cervical intraepithelial neoplasia grade 2/3 (CIN2/3) to cancer; a small increase in the cancer risk was estimated for women aged 35 or 40 years in case a substantial proportion of CIN2/3 showed fast progression to cancer. Our results indicate that primary hrHPV screening with a ten-yearly interval for hrHPV-negative women of age 40 and beyond will lead to a further reduction in lifetime cancer risk compared to five-yearly cytology, provided that precancerous lesions progress slowly to cancer.

    Human trafficking is a global human rights issue with long-range health consequences about which physicians are largely uneducated. Medical schools are uniquely positioned to address this gap. All future physicians, regardless of specialty, must learn to identify victims and refer them to trauma-informed treatment. Research and advocacy are needed to address the lack of rigorously evaluated curricula in this area, impact policy, and improve services for victims of this heinous form of exploitation.

  6. Forelimb preferences in human beings and other species: multiple models for testing hypotheses on lateralization

    Directory of Open Access Journals (Sweden)

    Elisabetta eVersace

    2015-03-01

    Full Text Available Consistent preferences in the use of right/left forelimbs are not exclusively present in humans. Functional asymmetries in forelimb use have been widely documented in a variety of vertebrate and invertebrate species. A matter of debate is whether non-human species exhibit a degree and consistency of functional forelimb asymmetries comparable to human handedness. The comparison is made difficult by the variability in hand use in humans and the few comparable studies conducted on other species. In spite of this, interesting continuities appear in functions such as feeding, object manipulation and communicative gestures. Studies on invertebrates show how widespread forelimb preferences are among animals, and the importance of experience for the development of forelimb asymmetries. Vertebrate species have been extensively investigated to clarify the origins of forelimb functional asymmetries: comparative evidence shows that selective pressures for different functions have likely driven the evolution of human handedness. Evidence of a complex genetic architecture of human handedness is in line with the idea of multiple evolutionary origins of this trait.

  7. Zoonotic Babesia: possibly emerging pathogens to be considered for tick-infested humans in Central Europe.

    Hunfeld, K P; Brade, V

    2004-04-01

    The three host-tick Ixodes (I.) ricinus is regarded as an important vector of tick-borne microorganisms pathogenic for humans in central Europe and is primarily known as the main vector of Borrelia (B.) burgdorferi and the virus causing tick-borne encephalitis (TBE), the most clinically relevant tick transmitted pathogens for humans in European countries. Furthermore, it is now well established that I. ricinus also transmits Ehrlichia (E.) phagocytophila, Babesia (Ba.) divergens, and Ba. microti, all agents of zoonotic infections in dear, sheep, cattle, dogs, and horses. In addition to their known zoonotic potential, recent molecular-epidemiological and seroepidemiological surveys as well as increasingly reported clinical cases of infections caused by these tick-borne organisms other than B. burgdorferi (TOBB) also strongly suggest a possible relevance of Babesia, Ehrlichia and Rickettsia for humans at risk in Europe. However, there are few medical microbiological investigations and epidemiological data on the distribution and relevance of Babesia for humans in our part of the northern hemisphere. There is also very little diagnostic and clinical knowledge on human babesiosis in many regions of Europe. Furthermore, sophisticated diagnostic tools designed for the reliable detection of the underlying pathogens, are not yet generally available to the microbiological laboratory. This review aims to provide basic information on human babesiosis and the most relevant causative pathogens of the disease in Europe and to draw attention to this parasitic infection as a possibly emerging and probably under-diagnosed disease in this part of the northern hemisphere.

    Adaptation is an eternal theme of biological evolution. The paper aims at exploring the conception of positive correlation between traditional Chinese medicine (TCM) and human homeostatic evolution based on medical perspective. Discussions mainly involve TCM conforming to natural laws and natural evolution of life, spontaneous harmonization of yin and yang and operating system of human self-healing, modern human immunology and human endogenous immune function in TCM, self-homeostasis of human micro-ecological state and balance mechanism on regulating base in TCM, as well as adaptation-eternal theme of biological evolution and safeguarding adaptability-value of TCM. In perspective of medicine, theory and practice of TCM are in positive correlation with human homeostatic evolution, and what TCM tries to maintain is human intrinsic adaptive capability to disease and nature. Therefore, it is the core value of TCM, which is to be further studied, explored, realized and known to the world.

  10. Sharing a bowl of tea.

    Sen, S

    1993-06-01

    Soshitsu Sen's keynote speech before a symposium on population and the environment is summarized unofficially by the editorial staff. The instability of human thinking is given as the cause for the present destruction of the environment. In a visit to the His Majesty King of Sweden, Sen remarked that stabilizing human minds can be achieved within the tea ceremony through "serving tea heartily, receiving it with gratitude, and offering it to another." In this way, the spirit of concern for others can be practiced in everyday life and tranquility of mind reached. News broadcasts of starving parents and children as victims of civil war are disheartening. The Japanese people are not suffering such hunger, even though the economy has not been as robust as desired. The analogy is provided in the story by Chuang Chou about King Hun Dun and King Xiu and man's good intentions, which nonetheless destroy the earth. Japan has experienced forest and environmental destruction on the road to economic prosperity and satisfaction of self-interests. The advice on living in accord with nature is to appreciate each season for its own changes. For example, when it is the winter season, the complaint is about the cold and the desire is for spring; but when spring comes, the desire is for the cooler weather of fall. the ordinary way is to appreciate all seasons and is the best way of sustaining a healthy environment. In the garden of the tea hut, humans enter without their worldly title, position, and means; at the water basin, hands and mouth are cleansed, and entrance is made through a small hole into the hut much the same as emerging from the womb. Worldly matters are dispensed with and purity of thought is shared in the sharing of the bowl of green tea, saying "after you" to one another. Christianity and the Way of Tea share the same symbols of purification. The black tea bowl is in harmony with the green tea. Fatigue is relieved when gazing upon the color green; examples are given

    To assure the shareholders can look for their "legal" attorneys to renew the secret, once the secret sharing scheme is initialized, a secret sharing scheme with inherited characteristic is constructed. In this scheme, each shareholder can produce a new share by his algorithm, which is equivalent to the primary one. Together with other shares, the primary secret can be renewed. Since this scheme is constructed not by replacing the primary share with a new share produced by the dealer in his primitive secret sharing scheme, so no matter how much shares the shareholder produces, these shares can not be gathered together to renew the secret in this scheme. Compared with the existing secret sharing schemes, this scheme provides more agility for the shareholders by investing each of them a function but not affect its security.

  12. Human Umbilical Cord Blood Cells or Estrogen may be Beneficial in Treating Heatstroke

    Full Text Available This current review summarized animal models of heatstroke experimentation that promote our current knowledge of therapeutic effects on cerebrovascular dysfunction, coagulopathy, and/or systemic inflammation with human umbilical cord blood cells (HUCBCs or estrogen in the setting of heatstroke. Accumulating evidences have demonstrated that HUCBCs provide a promising new therapeutic method against neurodegenerative diseases, such as stroke, traumatic brain injury, and spinal cord injury as well as blood disease. More recently, we have also demonstrated that postor pretreatment by HUCBCs may resuscitate heatstroke rats with by reducing circulatory shock, and cerebral nitric oxide overload and ischemic injury. Moreover, CD34+ cells sorted from HUCBCs may improve survival by attenuating inflammatory, coagulopathy, and multiorgan dysfunction during experimental heatstroke. Many researchers indicated pro(e.g. tumor necrosis factor-α [TNF-α] and anti-inflammatory (e.g. interleukin-10 [IL-10] cytokines in the peripheral blood stream correlate with severity of circulatory shock, cerebral ischemia and hypoxia, and neuronal damage occurring in heatstroke. It has been shown that intravenous administration of CD34+ cells can secrete therapeutic molecules, such as neurotrophic factors, and attenuate systemic inflammatory reactions by decreasing serum TNF-α but increasing IL-10 during heatstroke. Another line of evidence has suggested that estrogen influences the severity of injury associated with cerebrovascular shock. Recently, we also successfully demonstrated estrogen resuscitated heatstroke rats by ameliorating systemic inflammation. Conclusively, HUCBCs or estrogen may be employed as a beneficial therapeutic strategy in prevention and repair of cerebrovascular dysfunction, coagulopathy, and/or systemic inflammation during heatstroke.

    The Brazilian national curriculum guidelines for undergraduate medicine courses inspired and influenced the groundwork for knowledge acquisition, skills development and the perception of ethical values in the context of professional conduct. The evaluation of ethics education in research involving human beings in undergraduate medicine curriculum in Brazil, both in courses with active learning processes and in those with traditional lecture learning methodologies. Curricula and teaching projects of 175 Brazilian medical schools were analyzed using a retrospective historical and descriptive exploratory cohort study. Thirty one medical schools were excluded from the study because of incomplete information or a refusal to participate. Active research for information from institutional sites and documents was guided by terms based on 69 DeCS/MeSH descriptors. Curriculum information was correlated with educational models of learning such as active learning methodologies, tutorial discussions with integrated curriculum into core modules, and traditional lecture learning methodologies for large classes organized by disciplines and reviewed by occurrence frequency of ethical themes and average hourly load per semester. Ninety-five medical schools used traditional learning methodologies. The ten most frequent ethical themes were: 1--ethics in research (26); 2--ethical procedures and advanced technology (46); 3--ethic-professional conduct (413). Over 80% of schools using active learning methodologies had between 50 and 100 hours of scheduled curriculum time devoted to ethical themes whereas more than 60% of traditional learning methodology schools devoted less than 50 hours in curriculum time to ethical themes. The data indicates that medical schools that employ more active learning methodologies provide more attention and time to ethical themes than schools with traditional discipline-based methodologies. Given the importance of ethical issues in contemporary medical

    Psychiatry and related mental health fields, in particular psychotherapy, have a long history of close ties with the humanities. That bond has weakened, however, over the last few decades as medicalized views of mental health and treatment have emerged. In this paper, we explore the potential of the reintroduction of the humanities, specifically novels and related literary genre, into the supervision of student clinicians working with clients who have psychosis. We believe that incorporation of novels and related literary genre into supervision can lead to unique and deepened understanding of the experience of psychosis, and can create an opportunity for a working therapeutic alliance. The potential mechanisms that create these unique opportunities to understand psychopathology are explored, and considerations for the implications for treatment, training, and future research are presented.

  15. The emergence of human coronavirus EMC: how scared should we be?

    2013-04-09

    A novel betacoronavirus, human coronavirus (HCoV-EMC), has recently been detected in humans with severe respiratory disease. Further characterization of HCoV-EMC suggests that this virus is different from severe acute respiratory syndrome coronavirus (SARS-CoV) because it is able to replicate in multiple mammalian cell lines and it does not use angiotensin-converting enzyme 2 as a receptor to achieve infection. Additional research is urgently needed to better understand the pathogenicity and tissue tropism of this virus in humans. In their recent study published in mBio, Kindler et al. shed some light on these important topics (E. Kindler, H. R. Jónsdóttir, M. Muth, O. J. Hamming, R. Hartmann, R. Rodriguez, R. Geffers, R. A. Fouchier, C. Drosten, M. A. Müller, R. Dijkman, and V. Thiel, mBio 4[1]:e00611-12, 2013). These authors report the use of differentiated pseudostratified human primary airway epithelial cells, an in vitro model with high physiological relevance to the human airway epithelium, to characterize the cellular tropism of HCoV-EMC. More importantly, the authors demonstrate the potential use of type I and type III interferons (IFNs) to control viral infection.

    Various combinations of antibodies directed to cell surface markers have been used to isolate human and rhesus macaque hematopoietic stem cells (HSCs). These protocols result in poor enrichment or require multiple complex steps. Recently, a simple phenotype for HSCs based on cell surface markers from the signaling lymphocyte activation molecule (SLAM) family of receptors has been reported in the mouse. We examined the possibility of using the SLAM markers to facilitate the isolation of highly enriched populations of HSCs in humans and rhesus macaques. We isolated SLAM (CD150(+)CD48(-)) and non-SLAM (not CD150(+)CD48(-)) cells from human umbilical cord blood CD34(+) cells as well as from human and rhesus macaque mobilized peripheral blood CD34(+) cells and compared their ability to form colonies in vitro and reconstitute immune-deficient (nonobese diabetic/severe combined immunodeficiency/interleukin-2 γc receptor(null), NSG) mice. We found that the CD34(+) SLAM population contributed equally or less to colony formation in vitro and to long-term reconstitution in NSG mice compared with the CD34(+) non-SLAM population. Thus, SLAM family markers do not permit the same degree of HSC enrichment in humans and rhesus macaques as in mice.

During 2011-12, Alvin has undergone a transformation, including a larger personnel sphere with more & larger viewports to provide improved overlapping fields of view for the pilot & observers. The new Alvin will be certified for operations to 4500m depth initially, but the new sphere will be 6500m-rated and planned future upgrades will ultimately allow the vehicle to dive that deep, enabling human access to 98% of the global ocean floor. This will allow the study of processes and dynamics of Earth's largest ecosystem (the abyssal plains) as well as margin and ridge environments and the overlying water column. Meantime, the current upgrades to Alvin already include a suite of scientific enhancements including new HD video & still imaging, sophisticated data acquisition systems for seafloor observations and mapping, a new work platform with greater payload capacity and improved observer ergonomics. The new Alvin is poised to play important roles in core Earth and Life science programs and to serve large-scale programs such as the Ocean Observatory Initiative (OOI) and the International Ocean Discovery Program (IODP). It will continue to attract, engage and inspire a new generation of scientists & students to explore and study the largest ecosystem on Earth, just as it has done throughout its first half century.

  20. The right to be born: surrogacy and the legal control of human fertility.

    Science.gov (United States)

    Lupton, M L

    1989-01-01

    South African law, in common with many other legal systems, has exercised a strong measure of control over the fertility of its citizens via the sanction of illegitimacy and the prohibition of marriage (and hence legitimate children) between certain persons, e.g. those who fall within the so-called prohibited degrees of relationship. Until last year, when the Mixed Marriages Act was abolished, marriage across the colour line was prohibited in South Africa. The requirement of a valid consent by both prospective spouses in order to enter into marriage further excludes certain categories of persons from procreating legitimate children, e.g. the insane and mentally feeble, while the requirement of consummation will exclude certain categories of paraplegics from solemnizing a valid marriage. Age restrictions on marriages and the requirement of parental consent for minors are further factors limiting the individual's freedom to procreate. These restrictions have a well-established historical basis extending over many hundreds of years. They can be broadly categorised as having as their objective the preservation of the family unit. The above provisions were formulated at a time when the law never contemplated the spectacular advances in human biology that have produced the numerous artificial forms of conception, such as AID, IVF and surrogacy. The legislature, both in South Africa and elsewhere, at first adopted a neutral approach to this new fertility revolution and watched the courts struggle to adapt outmoded principles to the new technology. Legislation relating to AID and IVF eventually appeared in many jurisdictions; as a result of its delayed introduction public opinion had been educated to accept the new techniques and the legislation is by and large favourable to these new techniques. Not so, however, as far as surrogacy is concerned. South Africa, England and Australia have produced essentially negative legislation on this subject. Certain American states

In India rapid urbanization, industrialization, population explosion and migration of people in past two decades r esults in enormous growth in the field of road transportation. This resulted in increasing amount of the road traffic leading to increased risk for occurrence of road traffic accidents. In India road traffic injuries will be third leading cause of death by 2020 with the increase in the use of two wheelers and congestion and environmental pollution this mortality rate will continue to rise. Considering the preciousness of human lives, this study has been undertaken to analyse the pattern of injuries in Road Traffic Accidents Involving Two Wheelers to create awareness among the law enforcing authorities, transport authorities and public regarding two wheeler fatalities. A sincere attempt has been made in this study to analyse the distribution of the pattern of injuries sustained by two wheeler travellers, so that appropriate interventional strategies can be evolved at various levels and by different agencies. 147 Two wheeler Accident victims were randomly selected from 1063 road traffic accident cases brought t o the Institute of Forensic Medicine, Madras Medical College Chennai - 3 for routine medico legal examination.

  11. From 'human being' to 'social subject': "unfreezing" ergonomics and the implications for understanding and intervening health-disease process.

    Science.gov (United States)

    Morales, Karen Lange; García-Acosta, Gabriel

    2012-01-01

    Ergonomics has been successful in increasing productivity and comfort in the work arena. It has also contributed to reducing occupational accidents. Despite this, ergonomics is frequently limited to understanding the health-disease process related to human-technology interactions, as this process is more complex than what can be understood from an ergonomic evaluation. Recognising this limit, this work ontologically and epistemologically contrasts the notions of 'human being' and 'social subject', and concludes that the study object of ergonomics, or human-technology interaction, greatly depends on social aspects that nowadays are not tackled explicitly: route (history), project, structure, agency, motivations and power. It also analyses how participatory ergonomics tacitly includes many of these aspects, including some implications that the change of notion, from 'human being' to 'social subject', brings to the understanding of the health-disease process and the reduction of associated risks during human activities.

    According to the principle of enzyme reaction rate, healthy pent black bears' myocardial enzyme activity is assayed by visual colorimetry and compared with that of healthy human beings. The determination at 37℃ and the statistic analysis of the experimental data work out the following findings. For male black bears, the average CK activity is 163.20U/L, the confidence interval of its expected value (127.70 to 198.70)U/L, and the coefficient of variation 39.2%; the average CK-MB activity 21.62U/L, the confidential interval (17.72 to 25.51)U/L, and the coefficient of variation 34.26%; the average LDH activity 604.20U/L, the confidence interval (524.56 to 683.83)U/L, and the coefficient of variation 23.80%; the average HBDH activity 516.70U/L, the confidence interval (453.06 to 580.34)U/L, and the coefficient of variation 22.24%; the average GOT activity 69.70U/L, the confidence interval (60.21 to 79.19)U/L, and the coefficient of variation 24.59%. For female black bears, the average CK activity is 145.50U/L, the confidence interval (114.59 to 176.21)U/L, and the coefficient of variation 38.27%; the average CK-MB activity 18.84U/L, the confidence interval (14.64 to 23.04)U/L, and the coefficient of variation 40.34%; the average LDH activity 563.70U/L, the confidence interval (473.80 to 652.60)U/L, and the coefficient of variation 28.80%; the average of HBDH activity 475.50U/L, the confidence interval (412.10 to 538.40)U/L, and the coefficient of variation 24.07%; the average of GOT activity is 62.37U/L, the confidential interval (52.54 to 72.20)U/L, and the coefficient of variation 28.46%. The male black bear's average myocardium enzyme activities are slightly higher than those of the female. But the statistical results indicate that the difference is not significant.

    2002-01-01

    The library is launching a 'sharing resources@CERN' campaign, aiming to increase the library's utility by including the thousands of books bought by individual groups at CERN. This will improve sharing of information among CERN staff and users. Until now many people were unaware that copies of the same book (or standard, or journal) are often held not only by the library but by different divisions. (Here Eduardo Aldaz, from the PS division, and Isabel Bejar, from the ST division, read their divisional copies of the same book.) The idea behind the library's new sharing resources@CERN' initiative is not at all to collect the books in individual collections at the CERN library, but simply to register them in the Library database. Those not belonging to the library will in principle be unavailable for loan, but should be able to be consulted by anybody at CERN who is interested. "When you need a book urgently and it is not available in the library,' said PS Division engineer Eduardo Aldaz Carroll, it is a sham...

    According to the free radical theory of aging, reactive oxygen species (ROS) act as a driving force of the aging process, and it is generally believed that mitochondrial dysfunction is a major source of increased oxidative stress in tissues with high content of mitochondria, such as muscle or brain....... However, recent experiments in mouse models of premature aging have questioned the role of mitochondrial ROS production in premature aging. To address the role of mitochondrial impairment and ROS production for aging in human muscles, we have analyzed mitochondrial properties in muscle fibres isolated...... from the vastus lateralis of young and elderly donors. Mitochondrial respiratory functions were addressed by high-resolution respirometry, and ROS production was analyzed by in situ staining with the redox-sensitive dye dihydroethidium.

    Full Text Available Collecting evidences about organized crime act of sexual exploitation in human begins often is very difficult because of high level of organization, secrecy ant precaution taken during committing prostitution, pornography, sex tourism and human trafficking. On the other side, high illegal profit enable criminals to engage "expensive" and experienced lawyers, whose often make values and reliability of collected evidences questionable, appealing to irregularities during police collecting procedure. Among traditional criminalities methods and proofing activities, in the study, modern tendencies in special investigative measures and techniques are considered. After that, there is pointing at specificity, meaning and value of material tracks and objects, which are essential for proofing crime act or perpetrator’s guiltiness. On the end, there is pointing at importance of victims’ cooperation in collecting evidences about their sexual exploitation.

    We report the finding of a female brown dog tick, Rhipicephalus sanguineus (Acari: Ixodidae) on the scalp of a male patient in Porto Alegre, Rio Grande do Sul, Brazil. Human parasitism by this tick is rare and has seldomly been reported in the literature, despite its recognized importance since it can act as a vector of Rickettsia rickettsii, the agent of spotted fever.

    The recent demonstration that cancer immunotherapy extends patient survival has reinvigorated interest in elucidating the role of immunity in tumour pathogenesis. Experimental mouse tumour models have provided key mechanistic insights into host antitumour immune responses, and these have guided the development of novel treatment strategies. To accelerate the translation of these findings into clinical benefits, investigators need to gain a better understanding of the strengths and limitations of mouse model systems as tools for deciphering human antitumour immune responses.

    During recent decades, bioprospecting has become an important field of research, which looks for development alternatives, entry into global (environmental) markets, and the subsequent obtention of benefits under sustainable development principles. However, there is still so much to discuss regarding the social and environmental impacts produced by this activity, as well as its main limitations. To this end, the Forum/round-table discussion, entitled "Bioprospección, Etica y Sociedad" was organised to take place on 28 March 2012 at the National University of Colombia. Its main objective was to enrich our knowledge on bioprospecting considering the ethical considerations that involve society. The presentation given by Professor ROMEO CASABONA, regarding the connection between bioprospecting and the human genome deserves special attention and is presented below.

    Propolis is a natural product with a complex chemical composition. Its isolated compounds exert biological activities; however, its synergistic effects are unknown. The involvement of phenolic acids (caffeic - Caf, dihydrocinnamic - Cin and p-coumaric - Cou) alone or in combination was investigated in the action of propolis in human monocytes. Cell viability was analysed by MTT assay; TNF-α, IL-6 and IL-10 production by enzyme-linked immunosorbent assay (ELISA); cell markers expression by flow cytometry; colony-forming units were counted to assess the microbicidal activity; and H2 O2 production was analysed by colorimetric assay. Treatments did not affect monocytes viability. Propolis and combinations containing Caf enhanced TNF-α production by resting cells. Propolis, Cin, Cou and Caf + Cin stimulated IL-6 production. All treatments upregulated IL-10. In LPS-stimulated cells, treatments downregulated IL-6 and maintained TNF-α and IL-10 production. A lower TLR-2 expression was seen than propolis. Caf + Cin enhanced TLR-4 expression. Propolis, Caf and Caf + Cin stimulated H2 O2 production, whereas propolis, Cin, Cou, and Caf + Cin + Cou induced a higher fungicidal activity. Cin and Cin + Cou increased the bactericidal activity of human monocytes. Propolis activated human monocytes, and acids were involved differently in propolis activity. © 2016 Royal Pharmaceutical Society.

    Full Text Available Large companies which are experiencing barriers in innovation often take a radical step to acquire knowledge, namely acquisition. Though innovation is not the only reason, acquisition will result in the company wishes to achieve competitive advantage affected by the creation of ideas, creativity and innovation. The three points can be achieved more easily when the knowledge sharing within the organization / company runs well. However, the acquisition maybe impacts as a counter-attack for the knowledge sharing culture both in the acquisitor and company which obtains the acquisition. Therefore, a key to succeed the acquisition is a sharing culture among individuals within a company that runs well or even better. Individuals from the acquisitor and those of the company that obtains the acquisition can adapt to each other and have confidence in order not to hinder them to share knowledge. This study discusses in detail the potential impacts of an acquisition upon a knowledge sharing culture in a company.

  8. Pheromone signal transduction in humans: what can be learned from olfactory loss.

    2009-09-01

    Because humans seem to lack neuronal elements in the vomeronasal organ (VNO), many scientists believe that humans are unable to detect pheromones. This view is challenged by the observations that pheromone-like compounds, 4,16-androstadien-3-one (AND) and oestra-1,3,5(10),16-tetraen-3-ol (EST), activate the human hypothalamus. Whether these activations are mediated via VNO, venous blood or olfactory mucosa is presently unknown. To disentangle between the three alternatives, we conducted activation studies in 12 heterosexual males with chronic anosmia because of nasal polyps. Polyposis hampers signal transduction via the olfactory mucosa without interfering with the VNO or the pheromone transport via venous blood. Twelve healthy men served as controls. Subjects were investigated with (15)O-H(2)O PET during smelling of odorless air (base line), AND, EST, vanillin, and acetone. Smelling of EST activated the anterior hypothalamus in controls, but not anosmics. Neither did the anosmics display cerebral activations with AND or vanillin. Clusters were detected only with the trigeminal odorant acetone, and only in the thalamus, brainstem, the anterior cingulate, and parts of the sensorimotor cortex. Direct comparisons with controls (controls-anosmics) showed clusters in the olfactory cortex (amygdala and piriform cortex) with AND, vanillin, and acetone, and in the anterior hypothalamus with EST. The observed absence of olfactory and presence of trigeminal activations in anosmics indicates that polyposis primarily affected signal processing via the olfactory mucosa. The anosmics inability to activate the hypothalamus with EST, therefore, suggests that in healthy men EST signals were primarily transmitted via the olfactory system.

    The most publicly justifiable application of human cloning, if there is one at all, is to provide self-compatible cells or tissues for medical use, especially transplantation. Some have argued that this raises no new ethical issues above those raised by any form of embryo experimentation. I argue that this research is less morally problematic than other embryo research. Indeed, it is not merely morally permissible but morally required that we employ cloning to produce embryos or fetuses for the sake of providing cells, tissues or even organs for therapy, followed by abortion of the embryo or fetus.

  12. Panpsychism, pan-consciousness and the non-human turn: Rethinking being as conscious matter

    Full Text Available It is not surprising that in a time of intensified ecological awareness a new appreciation of nature and the inanimate world arises. Two examples are panpsychism (the extension of consciousness to the cosmos and deep incarnation (the idea that God was not only incarnated in human form but also in the non-human world. Consciousness studies flourish and are related to nature, the animal world and inorganic nature. A metaphysics of consciousness emerges, of which panpsychism is a good example. Panpsychism or panconsciousness or speculative realism endows all matter with a form of consciousness, energy and experience. The consciousness question is increasingly linked to the quantum world, which offers some option in bridging mind and reality, consciousness and matter. In this regard Kauffman’s notion of ‘triad’ is referred to as well as the implied idea of cosmic mind. This is related to the notion of ‘deep incarnation’ as introduced by Gregersen. Some analogical links are made between panpsychism and deep incarnation.

    Full Text Available One of the most serious threats to the European Union is the organised crime. The EU is continuously adapting its response in order to best respond to the situation. Among different types of organised crime, human beings trafficking is one of the most seriously crimes worldwide, representing also a gross violation of human rights. Very often behind the human beings trafficking is the organised crime because is one of the most profitable criminal activities in the world. The numbers are very scary because it is estimated that the trafficked people to or within the EU are reaching several hundred thousands a year. The present study is intending to discover how the European Union intends to fight against the human beings trafficking, since there is a need to have a coherent action at the European level because of the criminals can easily operate across border.

    Directory of Open Access Journals (Sweden)

    T. N. Van der Linde

    2006-12-01

    Full Text Available Purpose: Shared services is a viable business model that can be used by organisations to reduce costs and enhance efficiency and effectiveness in the organisation. The purpose of this trilogy of articles is to introduce shared services as a business model, and how to efficiently and effectively manage a shared services business unit. The purpose of the first article in the trilogy, introduces shared services as a business model, defines what shared services is, the transformation required to successfully implement a shared services business model, as well as the benefits that can be derived from implementing a shared services business model. Methodology: A comprehensive literature study was conducted in order to: - Define and describe shared services as a business model, - Compare shared services with centralisation and de-centralisation, - Determine and describe the transformation required to successfully implement shared services. Findings: In the article, a framework is generated to help organisations understand the business concept of shared services. This work has further potential: when applied correctly, there are both tangible and intangible benefits that can be accrued above cost savings. Implications: The findings of this article are important for organisations that are in the process of implementing or have implemented shared services, as it will assist the organisation in determining if shared services is the correct business model for them to implement. Value: This article provides an understanding of shared services and the business environment required to successfully implement a shared services business model. Value created by a shared services business model is further enhanced once the organisation has embarked on the successful implementation of a shared services business model, which is the primary objective of the second article, Implementation and continuous evolution in shared services.

  16. Is there a human right to be assisted in dying? [Temos um direito humano a ser assistido na morte?

    Directory of Open Access Journals (Sweden)

    Milene Tonetto

    2016-09-01

    Full Text Available This paper will focus on the issue of whether it is plausible to think about a human right to be assisted in dying. The right to be assisted in dying cannot be considered just a right of non-interference. It is better understood as a claim right because it demands assistance and positive actions. I will argue that the principles of individual autonomy and Kant’s notion of dignity taken independently cannot be considered plausible justification for the human right to be assisted in dying. Griffin’s personhood account points out that principles of liberty, minimum provision and autonomy must be taken together to justify human rights. Based on his theory, I will argue that a person with a terminal disease who was aware of her imminent death or who suffered from an intractable, incurable, irreversible disease may waive the right to life and choose death. Therefore, the right to life would not restrict the human right to be assisted in dying and a state that allowed the practice of assisted dying would not be disrespecting the human right to life. This article will defend that the personhood account is able to protect vulnerable people from making decisions under pressure and avoid the slippery slope objection.

  17. Current status of Mycobacterium avium subspecies paratuberculosis infection in animals & humans in India: What needs to be done?

    Directory of Open Access Journals (Sweden)

    Ajay Vir Singh

    2016-01-01

    Full Text Available Mycobacterium avium subspecies paratuberculosis (MAP has emerged as a major health problem for domestic livestock and human beings. Reduced per animal productivity of domestic livestock seriously impacts the economics of dairy farming globally. High to very high bioload of MAP in domestic livestock and also in the human population has been reported from north India. Presence of live MAP bacilli in commercial supplies of raw and pasteurized milk and milk products indicates its public health significance. MAP is not inactivated during pasteurization, therefore, entering into human food chain daily. Recovery of MAP from patients with inflammatory bowel disease or Crohn's disease and animal healthcare workers suffering with chronic gastrointestinal problems indicate a close association of MAP with a number of chronic and other diseases affecting human health. Higher bioload of MAP in the animals increases the risk of exposure to the human population with MAP. This review summarizes the current status of MAP infection in animals as well as in human beings and also highlights the prospects of effective management and control of disease in animals to reduce the risk of exposure to human population.

    Full Text Available Company Act of Republic of Serbia includes mechanism for the compulsory acquisition of the shareholdings of minority shareholders. Technically this procedure is effected on the basis of the shareholders assembly resolution. Buyer is shareholder who has at least 90% of share capital and at least 90% of votes. Shares owned by entity under his dominant influence will be treated as shares of that shareholder provided that dominant influence exists at least one year. Company's own shares, and shares subject o a pledge do not represent shares of other shareholders. There are several actions which may be treated as abuse of right of compulsory acquisition of shares.

  19. Integrating Sustainability Science with the Sciences of Human Well-being to Inform Design and Planning in an Urbanizing World

    Alberti, M.; Graumlich, L. J.; Frumkin, H.; Friedman, D.

    2012-12-01

    A sustainable human future requires both healthy ecosystems and communities in which people thrive, with opportunities for health, well-being, happiness, economic prosperity, and equity. To make progress towards this goal, two largely disparate communities of scholars and practitioners must come together: sustainability science needs to be integrated with the sciences of human health and well-being. The opportunity for such integration is particularly ripe for urbanizing regions which not only dominate energy and resource use but also increasingly represent the human habitat. We present a conceptual framework that integrates sustainability science with the sciences of human health and well-being to explicitly articulate testable hypotheses on the relationships between humans and their habitat. We are interested in human behaviors and metrics of health and well-being in relationship to the characteristics of the built environment at various scales from buildings to metro regions. Focusing on the U.S. Pacific Northwest (PNW) as a testbed, we are building on our current empirical studies on urban sprawl and ecosystem function including biodiversity, air quality, hydrological, biogeochemical, and human health to develop formal hypotheses on how alternative urban design and development patterns may influence health outcomes and well-being. The PNW is an ideal setting for this work because of the connected metropolitan areas within a region characterized by a spectacular diversity of aquatic and terrestrial ecosystems and deeply held cultural and political aspirations towards sustainability. The framework also highlights opportunities for translation of knowledge to practice in the design and planning of built environments. For example, understanding these associations is critical to assessing tradeoffs in design and planning strategies and exploring potential synergies that optimize both sustainability and human well-being. In complex systems such as cities, managers

  20. Shared intentional engagement through language and phenomenal experience.

    Science.gov (United States)

    Durt, Christoph

    2014-01-01

    This article introduces the notion of shared intentional engagement and argues that the current debate around intersubjective interaction can profit from taking that notion into account. Shared intentional engagement holds between people when they relate together to the same meaningful entities. For instance, when people talk about something, they share intentional engagement as long as they don't talk past each other. But what if the entity talked about involves perceptual experience-is the quality of one's experiences not something that cannot be conveyed to others through language? Against this widespread idea, this article takes up philosophical arguments for the intersubjectivity of, on the one hand, language, and, on the other hand, phenomenal experience. It contents that language and phenomenal experience both exhibit shared structures that enable shared intentional engagement. It then considers an example for how this result matches well with empirical research on "pop out" experiences. Because shared intentional engagement is fundamental for all kinds of human interaction, it necessitates interdisciplinary investigations that are frequently hindered by the assumption that the phenomenal experiences of humans are hidden to others.
