    Traditional approaches to the remediation of contaminated groundwater, such as pump-and-treat, have been used for many years for the treatment of groundwater contaminated with various organics. However the treatment of groundwater contaminated with organics and radionuclides has been considerably more challenging. Safety and Ecology Corporation (SEC) was recently faced with these challenges while designing a remediation system for the remediation of TCE-contaminated groundwater and soil at the RMI Extrusion Plant in Ashtabula, OH. Under contract with RMI Environmental Services (RMIES), SEC teamed with Regenesis, Inc. to design, implement, and execute a bioremediation system to remove TCE and associated organics from groundwater and soil that was also contaminated with uranium and technetium. The SEC-Regenesis system involved the injection of Hydrogen Release Compound (HRC), a natural attenuation accelerant that has been patented, designed, and produced by Regenesis, to stimulate the reductive dechlorination and remediation of chlorinated organics in subsurface environments. The compound was injected using direct-push Geoprobe rods over a specially designed grid system through the zone of contaminated groundwater. The innovative approach eliminated the need to extract contaminated groundwater and bypassed the restrictive limitations listed above. The system has been in operation for roughly six months and has begun to show considerable success at dechlorinating and remediating the TCE plume and in reducing the radionuclides into insoluble precipitants. The paper will provide an overview of the design, installation, and initial operation phase of the project, focusing on how traditional design challenges of remediating radiologically contaminated groundwater were overcome. The following topics will be specifically covered: a description of the mechanics of the HRC technology; an assessment of the applicability of the HRC technology to contaminated groundwater plumes

    Tohoku University was the first National University to admit three women students in Japan in 1913. To support the university's traditional ``open-door'' policy, various projects have been promoted throughout the university since its foundation. A government plan, the Third-Stage Basic Plan for Science and Technology, aims to increase the women scientist ratio up to 25% nationwide. In order to achieve this goal, the Tohoku Women's Hurdling Project, funded by the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT), was adopted in 2006. This project is threefold: support for child/family, improvement of facilities, and support for the next generation, which includes our Science Angels program. ``Science Angels'' are women PhD students appointed by the university president, with the mission to form a strong support system among each other and to become role-models to inspire younger students who want to become researchers. Currently, 50 women graduate students of the natural sciences are Science Angels and are encouraged to design and deliver lectures in their areas of specialty at their alma maters. Up to now, 12 lectures have been delivered and science events for children in our community have been held-all with great success.

  3. Defining the critical hurdles in cancer immunotherapy

    PubMed Central

    2011-01-01

    Scientific discoveries that provide strong evidence of antitumor effects in preclinical models often encounter significant delays before being tested in patients with cancer. While some of these delays have a scientific basis, others do not. We need to do better. Innovative strategies need to move into early stage clinical trials as quickly as it is safe, and if successful, these therapies should efficiently obtain regulatory approval and widespread clinical application. In late 2009 and 2010 the Society for Immunotherapy of Cancer (SITC), convened an "Immunotherapy Summit" with representatives from immunotherapy organizations representing Europe, Japan, China and North America to discuss collaborations to improve development and delivery of cancer immunotherapy. One of the concepts raised by SITC and defined as critical by all parties was the need to identify hurdles that impede effective translation of cancer immunotherapy. With consensus on these hurdles, international working groups could be developed to make recommendations vetted by the participating organizations. These recommendations could then be considered by regulatory bodies, governmental and private funding agencies, pharmaceutical companies and academic institutions to facilitate changes necessary to accelerate clinical translation of novel immune-based cancer therapies. The critical hurdles identified by representatives of the collaborating organizations, now organized as the World Immunotherapy Council, are presented and discussed in this report. Some of the identified hurdles impede all investigators; others hinder investigators only in certain regions or institutions or are more relevant to specific types of immunotherapy or first-in-humans studies. Each of these hurdles can significantly delay clinical translation of promising advances in immunotherapy yet if overcome, have the potential to improve outcomes of patients with cancer.

    2015-01-01

    Artificial insemination with homologous (AIH) or donor semen (AID) is nowadays a very popular treatment procedure used for many subfertile women worldwide. The rationale behind artificial insemination is to increase gamete density at the site of fertilisation. The sequence of events leading to today’s common use of artificial insemination traces back to scientific studies and experimentation many centuries ago. Modern techniques used in human artificial insemination programmes are mostly adapted from the work on cattle by dairy farmers wishing to improve milk production by using artificial insemination with sperm of selected bulls with well chosen genetic traits. The main reason for the renewed interest in artificial insemination in human was associated with the refinement of techniques for the preparation of washed motile spermatozoa in the early years of IVF. The history of artificial insemination is reviewed with particular interest to the most important hurdles and milestones. PMID:26175891

    2011-11-01

    The goal of this research is to identify science teachers' beliefs and conceptions that play an important role in shaping their understandings of and attempts to enact inclusive science teaching practices. We examined the work products, both informal (online discussions, email exchanges) and formal (papers, unit plans, peer reviews), of 14 teachers enrolled in a master's degree course focused on diversity in science teaching and learning. These emerging understandings were member-checked via a series of interviews with a subset of these teachers. Our analysis was conducted in two stages: (1) describing the difficulties the teachers identified for themselves in their attempts to teach science to a wide range of students in their classes and (2) analyzing these self-identified barriers for underlying beliefs and conceptions that serve to prohibit or allow for the teachers' understanding and enactment of equitable science instruction. The teachers' self-identified barriers were grouped into three categories: students, broader social infrastructure, and self. The more fundamental barriers identified included teacher beliefs about the ethnocentrism of the mainstream, essentialism/individualism, and beliefs about the meritocracy of schooling. The implications of these hurdles for science teacher education are discussed.

    Bacterial infections in animals impact our food production, leading to economic losses due to food rejection and the need for preventive and curative measures. Since the onset of the antibiotic era, the rise of antibiotic-resistant pathogens is causing scares in health care and food producing facilities worldwide. In the search of new therapeutics, re-evaluation of bacteriophage (phage) therapy, using naturally occurring bacterial viruses to tackle infections, is gaining interest. Many studies report about phage therapy success, showing the value and power of these natural viruses. Although phages carry some interesting traits and their basic biology is now well understood, this review argues that phage therapy has not revealed all of its secrets and many parameters remain understudied, making the outcome of phage therapy highly variable depending on the disease incidence. These difficulties include poorly understood mechanisms of phage penetration and distribution throughout the body, the variable expression and accessibility of phage receptors on the bacterial host in in vivo conditions and the unusual (non-linear) phage pharmacokinetics. These parameters are not easily measured in realistic in vivo settings, but are nevertheless important hurdles to overcome the high variability of phage therapy trials. This critical approach is in accordance with Goethe's statement; "Difficulties increase the nearer we get to the goal". However, since the importance of the goal itself also rises, both difficulties and goal justify the need for additional in depth research in this domain.

  10. Effect of Hurdle Technology in Food Preservation: A Review.

    PubMed

    Singh, Shiv; Shalini, Rachana

    2016-01-01

    Hurdle technology is used in industrialized as well as in developing countries for the gentle but effective preservation of foods. Hurdle technology was developed several years ago as a new concept for the production of safe, stable, nutritious, tasty, and economical foods. Previously hurdle technology, i.e., a combination of preservation methods, was used empirically without much knowledge of the governing principles. The intelligent application of hurdle technology has become more prevalent now, because the principles of major preservative factors for foods (e.g., temperature, pH, aw, Eh, competitive flora), and their interactions, became better known. Recently, the influence of food preservation methods on the physiology and behavior of microorganisms in foods, i.e. their homeostasis, metabolic exhaustion, stress reactions, are taken into account, and the novel concept of multi-target food preservation emerged. The present contribution reviews the concept of the potential hurdles for foods, the hurdle effect, and the hurdle technology for the prospects of the future goal of a multi-target preservation of foods.

  11. Flat, hurdle and steeple racing: risk factors for musculoskeletal injury.

    1998-11-01

    A retrospective case-control study was conducted to identify and quantify risk factors for serious musculoskeletal injury sustained at 4 Australian metropolitan racetracks. During the period of study (August 1988-July 1995) there were 196 cases from flat racing, 52 cases from hurdle racing and 53 cases from steeplechases. The incidences of fatal musculoskeletal injuries per start for flat, hurdle and steeple races were 0.06, 0.63 and 1.43% respectively. Logistic regression identified harder track surfaces, horses being older than age 3 years, one racecourse (Flemington) and jumping races as significant risk factors which increased the risk of musculoskeletal breakdown. The incidence of fatal musculoskeletal injuries for flat races at the 4 study tracks was similar to that reported in the UK but less than the USA. Death rates for hurdle and steeple races in the study population were higher than in the UK. Strategies to reduce the incidence of serious musculoskeletal injuries may include avoidance of excessively hard track surfaces through closer regulation of track moisture content; implementation of more rigorous prerace lameness examinations of horses, particularly older horses; and altering the design and number of jumps in hurdle and steeple races. The quantification of risk, as we have reported here, is the first step towards addressing the causes of musculoskeletal breakdown and should help in applying a reasoned approach to intervention measures that may be effective in reducing racing injuries.

  14. Quantifying the Ease of Scientific Discovery.

    Arbesman, Samuel

    2011-02-01

    It has long been known that scientific output proceeds on an exponential increase, or more properly, a logistic growth curve. The interplay between effort and discovery is clear, and the nature of the functional form has been thought to be due to many changes in the scientific process over time. Here I show a quantitative method for examining the ease of scientific progress, another necessary component in understanding scientific discovery. Using examples from three different scientific disciplines - mammalian species, chemical elements, and minor planets - I find the ease of discovery to conform to an exponential decay. In addition, I show how the pace of scientific discovery can be best understood as the outcome of both scientific output and ease of discovery. A quantitative study of the ease of scientific discovery in the aggregate, such as done here, has the potential to provide a great deal of insight into both the nature of future discoveries and the technical processes behind discoveries in science.

    Refugees and asylum seekers face a number of barriers to accessing health care and improved health status. These include language difficulties, financial need and unemployment, cultural differences, legal barriers and a health workforce with generally low awareness of issues specific to refugees. Importantly, current Australian government migration and settlement policy also impacts on access to health and health status. An adequate understanding of these 'hurdles to health' is a prerequisite for health providers and health service managers if they are to tailor health care and services appropriately. We include tables of available resources and entitlements to health care according to visa category to assist providers and managers.

  16. Hurdles in anticancer drug development from a regulatory perspective.

    2012-02-21

    Between January 2001 and January 2012, 48 new medicinal products for cancer treatment were licensed within the EU, and 77 new indications were granted for products already licensed. In some cases, a major improvement to existing therapies was achieved, for example, trastuzumab in breast cancer. In other cases, new fields for effective drug therapy opened up, such as in chronic myeloid leukemia, and renal-cell carcinoma. In most cases, however, the benefit-risk balance was considered to be only borderline favorable. Based on our assessment of advice procedures for marketing authorization, 'need for speed' seems to be the guiding principle in anticancer drug development. Although, for drugs that make a difference, early licensure is of obvious importance to patients, this is less evident in the case of borderline drugs. Without proper incentives and with hurdles inside and outside companies, a change in drug development cannot be expected; drugs improving benefit-risk modestly over available therapies will be brought forward towards licensure. In this Perspectives article, we discuss some hurdles to biomarker-driven drug development and provide some suggestions to overcome them.

  17. Technological hurdles to the application of intercalated graphite fibers

    Gaier, James R.

    1988-01-01

    Before intercalated graphite fibers can be developed as an effective power material, there are several technological hurdles which must be overcome. These include the environmental stability, homogeneity and bulk properties, connection procedures, and costs. Strides were made within the last several years in stability and homogeneity of intercalated graphite fibers. Bulk properties and connection procedures are areas of active research now. Costs are still prohibitive for all but the most demanding applications. None of these problems, however, appear to be unsolvable, and their solution may result in wide spread GOC application. The development of a relatively simple technology application, such as EMI shielding, would stimulate the solution of scale-up problems. Once this technology is developed, then more demanding applications, such as power bus bars, may be possible.

    The estimation and assessment of substance exposure (EASE) model has been under development and in use since the early 1990s. It is a general model that can be used to predict workplace exposure to any substance hazardous to health. The current EASE model (version 2.0) has been used widely in the risk assessment of new and existing chemicals by the UK Health and Safety Executive (HSE) and other regulatory agencies. EASE has also been distributed globally to over 200 users and therefore may have been used for many other purposes. Despite widespread use of the model, neither the development of its structure nor its underlying concepts and principles have been published in the open literature. Using surviving documentary evidence and discussions with key personnel, the creation and development of the model from 1992 to 2002 is described. The role of the HSE's National Exposure Database (NEDB) as the principal data source for the development of the model output exposure ranges is described. A number of problems and limitations of the model have been identified and the description of the model's development provides some explanation of their presence.

    Since the early 1990s, the Equal-Area Scalable Earth Grid (EASE-Grid) has been used for distribution of a variety of global gridded satellite data sets. It is conceptually easy to understand, but over time has been shown to suffer from some limitations that make it awkward for non-mapping experts to use properly. Most importantly, it is impossible to format in the widely popular GeoTIFF convention without reprojection. Based on many years of user comments and feedback, we have developed an improved EASE-Grid 2.0 definition, as an incremental set of changes to the original definition. EASE-Grid 2.0 has been adopted for use by the NASA MEaSUREs Northern Hemisphere terrestrial, sea ice and Greenland ice sheet snow data products, the Soil-Moisture Active-Passive (SMAP) soil moisture and freeze/thaw data sets, and the recently funded NASA MEaSUREs gridded passive microwave products. We describe how the new EASE-Grid 2.0 definition improves ease of access for users of the new data sets and ensures uncomplicated interoperability with modern, commonly used software tools.

    2002-08-18

    The crisis atmosphere surrounding electricity availability in California during the summer of 2001 produced two distinct phenomena in commercial energy consumption decision-making: desires to guarantee energy availability while blackouts were still widely anticipated, and desires to avoid or mitigate significant price increases when higher commercial electricity tariffs took effect. The climate of increased consideration of these factors seems to have led, in some cases, to greater willingness on the part of business decision-makers to consider highly innovative technologies. This paper examines three case studies of innovative technology adoption: retrofit of time-and-temperature signs on an office building; installation of fuel cells to supply power, heating, and cooling to the same building; and installation of a gas-fired heat pump at a microbrewery. We examine the decision process that led to adoption of these technologies. In each case, specific constraints had made more conventional energy-efficient technologies inapplicable. We examine how these barriers to technology adoption developed over time, how the California energy decision-making climate combined with the characteristics of these innovative technologies to overcome the barriers, and what the implications of hurdling these barriers are for future energy decisions within the firms.

    The current advances in chronobiology and the knowledge gained from chronotherapy of selected diseases strongly suggest that “the one size fits all at all times” approach to drug delivery is no longer substantiated, at least for selected bioactive agents and disease therapy or prevention. Thus, there is a critical and urgent need for chronopharmaceutical research (e.g., design and evaluation of robust, spatially and temporally controlled drug delivery systems that would be clinically intended for chronotherapy by different routes of administration). This review provides a brief overview of current delivery system intended for chronotherapy. In theory, such an ideal “magic pill” preferably with affordable cost, would improve the safety, efficacy and patient compliance of old and new drugs. However, currently, there are three major hurdles for the successful transition of such system from laboratory to patient bedside. These include the challenges to identify adequate (i) rhythmic biomaterials and systems, (ii) rhythm engineering modeling, perhaps using system biology and (iii) regulatory guidance. PMID:20438781

    Several gene therapy approaches have been designed for the treatment of cardiovascular diseases. A positive finding is that the safety of cardiovascular gene therapy has been excellent even in long-term follow-up. However, several hurdles to this field are still present. A major disappointing feature of the trials is that while preclinical and uncontrolled phase-I gene therapy trials have been positive, none of the randomized controlled phase-II/III cardiovascular gene therapy trials have shown clinically relevant positive effects. Low gene transfer efficiency seems to be associated with several trials. A sophisticated efficient delivery method for cardiovascular applications is still lacking and only low concentrations of the gene product are produced in the target tissues. Only a few gene therapy vectors can be produced in large scale. In addition, inflammatory reactions against vectors and inability to regulate gene expression are still present. Furthermore, a strong placebo effect is affecting the results in gene therapy trials, and long-term trials have become more difficult to conduct because of the multiplicity of therapies applied simultaneously on the patients. This review summarizes advances and obstacles of current cardiovascular clinical gene therapy trials.

    Under clinical development since the early 90’s and with two successfully approved drugs (Fomivirsen and Mipomersen), oligonucleotide-based therapeutics have not yet delivered a clinical drug to the market in the cancer field. Whilst many pre-clinical data has been generated, a lack of understanding still exists on how to efficiently tackle all the different challenges presented for cancer targeting in a clinical setting. Namely, effective drug vectorization, careful choice of target gene or synergistic multi-gene targeting are surely decisive, while caution must be exerted to avoid potential toxic, often misleading off-target-effects. Here a brief overview will be given on the nucleic acid chemistry advances that established oligonucleotide technologies as a promising therapeutic alternative and ongoing cancer related clinical trials. Special attention will be given towards a perspective on the hurdles encountered specifically in the cancer field by this class of therapeutic oligonucleotides and a view on possible avenues for success is presented, with particular focus on the contribution from nanotechnology to the field.

    Food is an important dissemination route for antibiotic-resistant bacteria. Factors used during food production and preservation may contribute to the transfer of antibiotic resistance genes, but research on this subject is scarce. In this study, the effect of temperature (7 to 37°C) and modified atmosphere packaging (air, 50% CO2-50% N2, and 100% N2) on antibiotic resistance transfer from Lactobacillus sakei subsp. sakei to Listeria monocytogenes was evaluated. Filter mating was performed on nonselective agar plates with high-density inocula. A more realistic setup was created by performing modified atmosphere experiments on cooked ham using high-density and low-density inocula. Plasmid transfer was observed between 10 and 37°C, with plasmid transfer also observed at 7°C during a prolonged incubation period. When high-density inocula were used, transconjugants were detected, both on agar plates and cooked ham, under the three atmospheres (air, 50% CO2-50% N2, and 100% N2) at 7°C. This yielded a median transfer ratio (number of transconjugants/number of recipients) with an order of magnitude of 10(-4) to 10(-6). With low-density inocula, transfer was only detected under the 100% N2 atmosphere after 10-day incubation at 7°C, yielding a transfer ratio of 10(-5). Under this condition, the highest bacterial density was obtained. The results indicate that low temperature and modified atmosphere packaging, two important hurdles in the food industry, do not necessarily prevent plasmid transfer from Lactobacillus sakei subsp. sakei to Listeria monocytogenes.

    1980-01-01

    Once the United States' space program had progressed from Earth's orbit into outerspace, the prospect of building and maintaining a permanent presence in space was realized. To accomplish this feat, NASA launched a temporary workstation, Skylab, to discover the effects of low gravity and weightlessness on the human body, and also to develop tools and equipment that would be needed in the future to build and maintain a more permanent space station. The structures, techniques, and work schedules had to be carefully designed to fit this unique construction site. The components had to be lightweight for transport into orbit, yet durable. The station also had to be made with removable parts for easy servicing and repairs by astronauts. All of the tools necessary for service and repairs had to be designed for easy manipulation by a suited astronaut. Construction methods had to be efficient due to the limited time the astronauts could remain outside their controlled environment. In lieu of all the specific needs for this project, an environment on Earth had to be developed that could simulate a low gravity atmosphere. A Neutral Buoyancy Simulator (NBS) was constructed by NASA's Marshall Space Flight Center (MSFC) in 1968. Since then, NASA scientists have used this facility to understand how humans work best in low gravity and also provide information about the different kinds of structures that can be built. Pictured is a Massachusetts Institute of Technology (MIT) student working in a spacesuit on the Experimental Assembly of Structures in Extravehicular Activity (EASE) project which was developed as a joint effort between MFSC and MIT. The EASE experiment required that crew members assemble small components to form larger components, working from the payload bay of the space shuttle. The MIT student in this photo is assembling two six-beam tetrahedrons.

    Pork sausages developed using hurdle technology was evaluated during refrigerated storage (4 ± 1°C). Hurdles incorporated were low pH, low water activity, vacuum packaging and post package reheating. Dipping in potassium sorbate solution prior to vacuum packaging was also tried. Hurdle treatment significantly (p <0.05) reduced the rate of deterioration of quality characteristics of pork sausages during storage, as indicated by TBARS and tyrosine values. Incorporation of hurdles decreased the growth of different spoilage and pathogenic microorganisms. Combination of pH, water activity, vacuum packaging and reheating inhibited the growth of yeast and molds up to 12 days, while additional dipping of sausages in 1% potassium sorbate solution prior to packaging inhibited their growth even on 30(th) day of storage. Incorporation of hurdles resulted in initial reduction in all the sensory attributes, but they helped to maintain these attributes for significantly longer period compared to control. Hurdle treated sausages exhibited no spoilage signs even on day 30, while the control sausages were found acceptable only up to 18 days.

  9. Capacity additions ease tight methanol supply

    Two menthanol plants now in operation - one in the U.S., the other in Chile - will boost global supplies of methanol more than 375 million gal annually. This large capacity addition and smaller expansions in other parts of the world will exceed demand growth during 1988 and 1989, easing the squeeze on supplies. As the result of increased supplies, methanol prices could slip slightly in the fourth quarter. They are more likely to decline next year, however. The two plants, which started up in August, are owned and operated by Tenneco Oil Co. Processing and Marketing and by Cape Horn Methanol (CHM). The Tenneco plant, located in Pasadena, Tex., was restarted after a shutdown in 1982 when prices for methanol were low. It now is running at full capacity of 125 million gal per year. The plant uses the low-pressure process technology of Lurgi, reportedly requiring for feedstock and energy between 100,000 and 125,000 cu ft of methane per gallon. Global trade in methanol smooths out the supply and demand inconsistencies. Surging methanol demand in the U.S. and in Western Europe has been met by imports from areas where methanol production is most economical - that is, where natural gas is readily available and has no other application as high in value. Canada, Chile, and Trinidad are examples of those areas.

In 2005, Ames licensed FACET to Flight Explorer Inc., for integration into its Flight Explorer (version 6.0) software. The primary FACET features incorporated in the Flight Explorer software system alert airspace users to forecasted demand and capacity imbalances. Advance access to this information helps dispatchers anticipate congested sectors (airspace) and delays at airports, and decide if they need to reroute flights. FACET is now a fully integrated feature in the Flight Explorer Professional Edition (version 7.0). Flight Explorer Professional offers end-users other benefits, including ease of operation; automatic alerts to inform users of important events such as weather conditions and potential airport delays; and international, real-time flight coverage over Canada, the United Kingdom, New Zealand, and sections of the Atlantic and Pacific Oceans. Flight Explorer Inc. recently broadened coverage by partnering with Honeywell International Inc.'s Global Data Center, Blue Sky Network, Sky Connect LLC, SITA, ARINC Incorporated, Latitude Technologies Corporation, and Wingspeed Corporation, to track their aircraft anywhere in the world.

    This paper presents a method of monocular human motion tracking for estimation of hurdle clearance kinematic parameters. The analysis involved 10 image sequences of five hurdlers at various training levels. Recording of the sequences was carried out under simulated starting conditions of a 110 m hurdle race. The parameters were estimated using the particle swarm optimization algorithm and they are based on analysis of the images recorded with a 100 Hz camera. The proposed method does not involve using any special clothes, markers, inertial sensors, etc. As the quality criteria, the mean absolute error and mean relative error were used. The level of computed errors justifies the use of this method to estimate hurdle clearance parameters.

    EASE (Estimation and Assessment of Substance Exposure) is a general model that may be used to predict workplace exposure to a wide range of substances hazardous to health. First developed in the early 1990s, it is now in its second Windows version. This paper provides a critical assessment of the utility and performance of the EASE model, and on the basis of this review, recommendations for the structure of a revised model are outlined. Twenty-seven stakeholders were interviewed about their previous use of EASE, perceived advantages and limitations of the model and suggestions for improvement. A subset of stakeholders was contacted on a second occasion to determine their views on the preferred outputs for an ideal exposure assessment model. Overall, stakeholders felt that the model should be updated to provide more accurate and precise exposure assessments. However, users also expressed the view that the simplicity and usability of the software model should not be compromised. Six studies investigating the validity of the inhalation exposure assessment section of EASE were identified. These showed that the model generally either predicted close to the measured exposures or overestimated exposure; though performance was highly variable. Two studies investigated the validity of the dermal exposure assessment and found that EASE produced considerable overestimates of actual dermal exposure (the amount of a substance that actually lands on the skin). A conceptual model of exposure was developed to investigate whether the structure of the EASE model is appropriate. Although EASE has a number of characteristics that describe exposure, it is a greatly simplified model and does not include all the important exposure determinants. More importantly, EASE can produce estimates of exposure that are ambiguous or incomplete. Our conceptual model may provide a rational basis for developing an improved version of EASE but further consultation is needed to decide the purpose and

  17. The validity of the EASE expert system for inhalation exposures.

    2005-03-01

    Estimation and Assessment of Substance Exposure (EASE) is a computerized expert system developed by the UK Health and Safety Executive to facilitate exposure assessments in the absence of exposure measurements. The system uses a number of rules to predict a range of likely exposures or an 'end-point' for a given work situation. The purpose of this study was to identify a number of inhalation exposure measurements covering a wide range of end-points in the EASE system to compare with the predicted exposures. Occupational exposure data sets were identified from previous research projects or from consultancy work. Available information for each set of measurements was retrieved from archive storage and reviewed to ensure that it was adequate to enable EASE (version 2) predictions to be obtained. Exposure measurements and other relevant contextual data were abstracted and entered into a computer spreadsheet. EASE predictions were then obtained for each task or job and entered into the spreadsheet. In addition, we generated a random exposure range for each data set for comparison with the EASE predictions. Finally, we produced exposure assessments for a subset of the data using a structured subjective assessment method. We were able to identify approximately 4000 inhalation exposure measurements covering 52 different scenarios and 28 EASE end-points. The data included measurements of solvent vapours, non-fibrous dusts and fibres. In 62% of the end-points the EASE predictions were generally greater than the exposure measurements and in 30% of the end-points the EASE estimates were comparable with the measurements. The random allocation of exposure ranges was, as expected, less reliable than EASE, although there were still about one-third of the cases where the randomly generated exposure ranges generally agreed with the measurements. The structured subjective assessments undertaken by a human expert produced exposure estimates in better agreement with the measurements

    Within the framework of European risk assessment of new and existing substances, the EASE model (Estimation and Assessment of Substance Exposure) is often applied to assess inhalative exposure at workplaces. To contribute to the validation of this model, single EASE scenarios were compared with independent measurement data on inhalative exposure to vapors and dusts. For this purpose, workplace measurements obtained in the areas of production, textile printing and coating, screen printing and offset printing, the rubber industry, and the plastics processing industry as well as flame spraying were used. A good correspondence between model estimates and measurement data was found in the case of exposure to vapors for the production of chemical substances in closed systems (EASE scenario: closed system without breaching) and for procedural control works at mainly automated printing workplaces (EASE scenarios: non dispersive use, segregation, low/medium volatility). For the handling of powdery substances measurement results obtained during weighing and filling works, in part semiautomatic, were compared with the EASE estimates for the scenario: dry manipulation, with/without local exhaust ventilation. Good correspondence was estimated if approx. 1 t to 200 t powdery substances were handled per shift. For the EASE scenarios "direct handling with natural ventilation/with local exhaust ventilation," high discrepancies exist between model prediction and measurement results obtained during manual screen printing or the preparation of printing inks.

  19. Hurdles to the introduction of new therapies for immune-mediated kidney diseases.

    Innovative immunotherapies continue to markedly benefit many disciplines in clinical medicine but disappointingly, these benefits have not translated to the treatment of kidney diseases despite encouraging findings from preclinical models of kidney dysfunction. This lack of progress in nephrology might relate to the unique biology of the kidney. More likely, this lack of progress relates to conceptual hurdles in the application of newer therapies to renal disease. In this Review we discuss seven hurdles that must be addressed in order to appropriately assess and introduce immunologic therapies for immune-mediated kidney disease: the use of appropriate criteria to define disease categories; issues relating to the heterogeneity of kidney diseases and how this heterogeneity affects approaches to treatment; issues related to the rarity of most kidney diseases; the paucity of good animal models of human kidney disease; issues relating to trial design; problems with current approaches to the identification and use of appropriate and feasible study end points; and a lack of adequate biomarkers of intrarenal inflammation and parenchymal injury. We suggest that overcoming these hurdles, in addition to searching for better therapeutic targets, will be necessary to progress the treatment of immune-mediated kidney disease into a new age of drug therapy.

    PurposeThe OptEase vena cave filter (Cordis, Piscataway, NJ) is commercially available as a retrievable or permanent filter with short recommended indwelling time, presumably due to extensive contact of the filter side struts with the inferior vena cava wall and subsequent neointimal hyperplasia leading to incorporation. Our purpose was to evaluate OptEase filter retrievals with a long indwelling time period that required unconventional retrieval techniques.Materials and MethodsWe retrospectively reviewed patients who underwent OptEase filter retrieval with long undwelling times requiring additional maneuvers for retrieval. Techniques used included rigid endobronchial forceps dissection and wire-through-loop snare. Each patient underwent postretrieval venogram to evaluate for possible complications. In addition, patients had clinical follow-up 2 weeks after the retrieval procedure.ResultsThere were three patients (2 women, 1 man; average age 64 years) who underwent OptEase filter retrieval. The mean indwelling time was 6.4 months. The indwelling filters were successfully retrieved. There were no complications. Postprocedural follow-up showed no clinical pathology.ConclusionUnconventional techniques aided in the retrieval of OptEase filters with long indwelling times.

  2. EASE vectors for rapid stable expression of recombinant antibodies.

    2003-01-01

    Over the past 10 years, monoclonal antibodies and antibody fragments have become an increasingly important source of therapeutic molecules in the biotechnology industry. Drug development strategies rely on screening large numbers of candidate molecules in search of an optimized drug candidate. This strategy requires efficient production of ten to a few hundred milligrams of candidate molecules for screening in bioassays and animal models. Typically, this amount of recombinant protein expression involves large numbers of transient transfections or cloning of a recombinant cell line. Both of these approaches are time-consuming and labor-intensive. In this report, we describe the application of an EASE vector system that is capable of generating stable pools of transfected Chinese hamster ovary cells. These pooled populations of cells produce high quantities of antibody candidates without labor-intensive cloning in a 3-5 week time frame. When an optimal drug candidate has been selected, pools generated with EASE-containing vectors can also be used in subsequent cloning steps to make cell lines with improved expression levels. We demonstrate that EASE increases expression in nonamplified pools in addition to increasing amplification and viability of clonal cell lines generated with the EASE-containing vectors compared with pools and cell lines generated without EASE.

    An understanding of the perceived importance of a variety of factors affecting the ease of handling of sheep and the interactions between these factors is valuable in improving profitability and welfare of the livestock. Many factors may contribute to animal behaviour during handling, and traditionally these factors have been assessed in isolation under experimental conditions. A human social component to this phenomenon also exists. The aim of this study was to gain a deeper understanding of the importance of a variety of factors affecting ease of handling, and the interactions between these from the perspective of the livestock transporter. Qualitative interviews were used to investigate the factors affecting sheep behaviour during handling. Interview transcripts underwent thematic analysis. Livestock transporters discussed the effects of attitudes and behaviours towards sheep, helpers, facilities, distractions, environment, dogs and a variety of sheep factors including breed, preparation, experience and sex on sheep behaviour during handling. Transporters demonstrated care and empathy and stated that patience and experience were key factors determining how a person might deal with difficult sheep. Livestock transporters strongly believed facilities (ramps and yards) had the greatest impact, followed by sheep experience (naivety of the sheep to handling and transport) and breed. Transporters also discussed the effects of distractions, time of day, weather, dogs, other people, sheep preparation, body condition and sheep sex on ease of handling. The concept of individual sheep temperament was indirectly expressed.

  9. Understanding the adaptive response in vertebrates: the phenomenon of ease and ease response during post-stress acclimation.

    PubMed

    Subhash Peter, M C

    2013-01-15

    Vertebrates have evolved mechanisms to perceive stressors that arise either from their body or from the environment. Consequently, a state of stress and stress response occur in fish which is characterized by a disturbed physiological homeostasis. The pattern of stress response becomes complex as a result of neuroendocrine involvement and shows varied magnitudes in fishes depending on the nature and the severity of stressors. The integrated and compensatory physiological modifications in fishes during their early phase of adaptive response favor them to accommodate the imposed stressor through the process of stress acclimation. In contrast, with the direction of neuroendocrine signals, a phase of recovery often called post-stress acclimation occurs if the animal gets away from the stressor exposure. During this late phase of adaptive response, physiological modifications operate in favor of the animal that reduces the magnitude of stress response and finally to a phase of normality as animals possess the urge to correct its disrupted homeostasis. The phenomenon of ease and its response thus reduces the allostatic load, resets the homeostatic state through physiologic processes and corrects the stress-induced homeostatic disturbance with the aid of neuroendocrine signals. Ample evidences are now available to support this novel concept of ease and ease response where mitigation of the intensity of stress response occurs physiologically. Treatment of fish with melatonin or serotonin precursor tryptophan can modify the magnitude of stress response as evident in the pattern of tested physiological indices. In addition to cortisol, thyroid hormone as a major stress modifier hormone is involved in the regulation of ease response in fish probably due to the mechanisms involving inter-hormonal interference. Understanding the mechanisms of adaptive responses in vertebrates thus warranties more studies on the physiology of ease and its response.

  10. Point-of-care diagnostics: will the hurdles be overcome this time?

    2006-07-01

    Point-of-care diagnostics have been proposed as the latest development in clinical diagnostics several times in the last 30 years; however, they have not yet fully developed into a business sector to match the projections. This perspective examines the reasons for past failures and the failure of technology to meet user needs. Advances have taken place in the last few years that effectively remove technology as a barrier to the development of point-of-care testing. Even regulatory issues regarding how products are developed and claims supported have been absorbed, understood and now accepted. The emphasis here is on the possible favorable aspects that are novel this time around. These changes have arisen as a result of the situation with global healthcare economics and the pressure from patients to be treated more like customers. The final hurdles relate to the conflict between diagnosis with the patient present and treated as soon as the point-of-care result is available and the entrenched positions of the central laboratory, the suppliers and their established distribution chains, and the way in which healthcare budgets are allocated. The ultimate hurdle that encapsulates all of these issues is reimbursement, which is the final barrier to a significant point-of-care diagnostics market--without reimbursement there will be no market.

    Random effect panel data hurdle models are established to research the daily crash frequency on a mountainous section of highway I-70 in Colorado. Road Weather Information System (RWIS) real-time traffic and weather and road surface conditions are merged into the models incorporating road characteristics. The random effect hurdle negative binomial (REHNB) model is developed to study the daily crash frequency along with three other competing models. The proposed model considers the serial correlation of observations, the unbalanced panel-data structure, and dominating zeroes. Based on several statistical tests, the REHNB model is identified as the most appropriate one among four candidate models for a typical mountainous highway. The results show that: (1) the presence of over-dispersion in the short-term crash frequency data is due to both excess zeros and unobserved heterogeneity in the crash data; and (2) the REHNB model is suitable for this type of data. Moreover, time-varying variables including weather conditions, road surface conditions and traffic conditions are found to play importation roles in crash frequency. Besides the methodological advancements, the proposed technology bears great potential for engineering applications to develop short-term crash frequency models by utilizing detailed data from field monitoring data such as RWIS, which is becoming more accessible around the world.

    When reporting a subject's mean movement pattern, it is important to ensure that reported values are representative of the subject's typical movement. While previous studies have used the mean of 3 trials, scientific justification of this number is lacking. One approach is to determine statistically how many trials are required to achieve a representative mean. This study compared 4 methods of calculating the number of trials required in a hopping movement to achieve a representative mean. Fifteen males completed 15 trials of a lateral hurdle hop. Range of motion at the trunk, pelvis, hip, knee, and ankle, in addition to peak moments for the latter 3 joints were examined. The number of trials required was computed using a peak intraclass correlation coefficient method, sequential analysis with a bandwidth of acceptable variance in the mean, and a novel method based on the standard error of measurement (SEMind). The number of trials required across all variables ranged from 2 to 12 depending on method, joint, and anatomical plane. The authors advocate the SEMind method as it demonstrated fewer limitations than the other methods. Using the SEMind, the required number of trials for a representative mean during the lateral hurdle hop is 6.

Cleave, and Sherwood C. Spring; and Rodolpho Neri Vela, payload specialist. Launched aboard the Space Shuttle Atlantis November 28, 1985 at 7:29:00 pm (EST), the STS-61B mission's primary payload included three communications satellites: MORELOS-B (Mexico); AUSSAT-2 (Australia); and SATCOM KU-2 (RCA Americom). Two experiments were conducted to test assembling erectable structures in space: EASE (Experimental Assembly of Structures in Extravehicular Activity), and ACCESS (Assembly Concept for Construction of Erectable Space Structure). In a joint venture between NASA/Langley Research Center in Hampton, Virginia, and the Marshall Space Flight Center (MSFC), the EASE and ACCESS were developed and demonstrated at MSFC's Neutral Buoyancy Simulator (NBS). In this STS-61B onboard photo, astronaut Spring was working on the EASE during an Extravehicular Activity (EVA). The primary objective of this experiment was to test the structural assembly concepts for suitability as the framework for larger space structures and to identify ways to improve the productivity of space construction.

    The Tissue Engineering and Regenerative Medicine International Society-North America (TERMIS-NA) Industry Committee was formed in February 2009 to address the common roadblocks (i.e., hurdles) in the commercialization of tissue engineering/regenerative medicine products for its members. A semiquantitative online opinion survey instrument that delineated potentially sensitive hurdles to commercialization in each of the TERMIS constituency groups that generally participate in the stream of technology commercialization (academia, startup companies, development-stage companies, and established companies) was developed. The survey was opened to each of the 863 members of TERMIS-NA for a period of 5 weeks from October to November 2009. By its conclusion, 215 members (25%) had responded. Their proportionate numbers were closely representative of TERMIS-NA constituencies. The resulting data delineate what each group considers to be its most difficult and also its easiest hurdles in taking a technology to full product development. In addition, each group ranked its perception of the difficult and easy hurdles for all other groups, enabling an assessment of the degree of understanding between groups. The data depict not only critical hurdles in the path to commercialization at each stage in product development but also a variable understanding of perceptions of hurdles between groups. This assessment has provided the Industry Committee with activity foci needed to assist individual groups in the technology-commercialization stream. Moreover, the analysis suggests that enhanced communication between groups engaged in commercialization will be critical to the successful development of products in the tissue engineering/regenerative medicine sector.

    Capitalizing on the almost 2.2 million service members returning from Operation Iraqi Freedom and New Dawn (OIF) in Iraq, and Operation Enduring Freedom (OEF) in Afghanistan, baccalaureate educators are encouraged to create realistic, applicable nursing transitional programs for the health and health-related oriented military veterans. Opportunities, hurdles, and solutions related to the veteran's unique socio-economic circumstances of education, finances, and advisement are provided so the potential veteran student is successful within the university's milieu. Transitional nursing educational interventions related to assessment, didactic, and clinical used by two baccalaureate nursing curriculums, including the eLineMilitary* (ELM) Program, provide approaches of how to propel the veteran's journey toward graduation in a professional nursing program. These interventions include modular didactic, competency based education, as well as the concentrated, collegial time within the Faculty/Clinical Coach triad for essential role modeling, care, and skills.

    Background The treatment of severe full-thickness skin defects represents a significant and common clinical problem worldwide. A bio-engineered autologous skin substitute would significantly reduce the problems observed with today's gold standard. Methods Within 15 years of research, the Tissue Biology Research Unit of the University Children's Hospital Zurich has developed autologous tissue-engineered skin grafts based on collagen type I hydrogels. Those products are considered as advanced therapy medicinal products (ATMPs) and are routinely produced for clinical trials in a clean room facility following the guidelines for good manufacturing practice (GMP). This article focuses on hurdles observed for the translation of ATMPs from research into the GMP environment and clinical application. Results and Conclusion Personalized medicine in the field of rare diseases has great potential. However, ATMPs are mainly developed and promoted by academia, hospitals, and small companies, which face many obstacles such as high financial burdens. PMID:27781022

    Demographic changes in the world population will cause a significant increase in the number of new cases of cancer. To handle this challenge, societies will need to adapt how they approach cancer prevention and treatment, with changes to the development and uptake of innovative anticancer drugs playing an important role. However, there are obstacles to implementing innovative drugs in clinical practice. Prior to being incorporated into daily practice, the drug must obtain regulatory and reimbursement approval, succeed in changing the prescription habits of physicians, and ultimately gain the compliance of individual patients. Developing an anticancer drug and bringing it into clinical practice is, therefore, a lengthy and complex process involving multiple partners in several areas. To optimize patient treatment and increase the likelihood of implementing health innovation, it is essential to have an overview of the full process. This review aims to describe the process and discuss the hurdles arising at each step. PMID:25525460

    2015-01-01

    A basic principle in the bacterial resistance against lethal stresses is that exposure of microbial cells to a sublethal hurdle (e.g., pH 5.0, 3% NaCl, or 48°C) may induce resistance to lethal level of the same or different stress. The latter is called "cross-tolerance" and the bacteria experiencing such situations are termed "stress-hardened". The majority of scientific reports on the adaptive responses of bacteria to stresses have recently addressed the need to elucidate the underlying mechanisms controlling bacterial stress response. This in turn, will assist in the efficient application of the multiple hurdle approach, e.g., by selecting specific sanitizers, combining stress treatments or antimicrobials, especially in mild processing, against specific cellular targets, eliminating the possibility of the development of stress adapted cells. Common scientific approaches for studying the link between phenotype (e.g., inactivation, survival, or growth) and physiology is the assessment of global transcriptional changes (up- or down-regulation) or those of certain genes, as well as of proteins involved in certain metabolic pathways, occurring during exposure to stress. This may also be performed in parallel to comparative evaluation of the phenotypic response of wild and mutant strains. The post-genomics research on foodborne pathogens has extended our knowledge beyond their phenotypic behavior and may offer mechanistic insights in the following: (i) the top-down approach (induction), which is the search of the underlying mechanisms (low level) responsible for a specific phenotype based on "-omic" studies; and (ii) the bottom-up approach (deduction), which starts from intracellular level and forms a mechanistic (functional) basis for the cellular response. All these may eventually enable the development of mechanistic microbial models and efficient strategies for controlling survival and growth of pathogens in foods.

    Background: Present times have seen an alarming increase in incidence of crimes by juveniles and of mass destruction that Highlight the preponderance of individual age estimation. Of the numerous techniques employed for age assessment, dental age estimation (DAE) and its correlation with chronological age (CA) have been of great significance in the recent past. Demirjian system, considered as gold standard in DAE is a simple and convenient method for DAE, though,, although, referring to multiple tables make it cumbersome and less eco friendly due to excessive paper load. Aim: The present study was aimed to develop a comprehensive chart (DAEcc) inclusive of all Demirjian tables and developmental stages of teeth and also to as well as to test the operator ease of 50 undergraduate dental students in performing DAE using this chart. Materials and Methods: The study was performed in two stages, wherein the first stage was aimed at formulation of the comprehensive chart (DAECC) which included pictorial representation of calcification stages, the Federation Dentaire Internationale notation of the teeth, and the corresponding scores for each stage with a concluding column at the end to enter the total score. The second stage assessed the applicability of the ease of DAE by DAECC, whereby fifty 2nd year BDS students were asked to trace the calcification stages of the seven permanent left mandibular teeth on a panorex, identify the correct stage, assign the corresponding score, and to calculate the total score for subsequent dental age assessment. Results and Conclusions: showed that average time taken by the students for tracing seven mandibular teeth was 5 min and for assessment of dental age was 7 min. The total time taken for DAE was approximately 12 min, thus making the procedure less time consuming. Hence, this study proposes the use of DAEcc for age estimation due to ease in comprehension and execution of Demirjian system. PMID:28123280

  2. States leverage telepsychiatry solutions to ease ED crowding, accelerate care.

    PubMed

    2015-02-01

    Many states are having success turning to telepsychiatry-based solutions to connect mental health patients with needed care while also decompressing crowded EDs. Just one year into a statewide telepsychiatry initiative in North Carolina (NC-STeP), administrators say the approach has saved as much as $7 million, and hospital demand for the service is higher than anticipated. In Texas, mental health emergency centers (MHEC) that use telepsychiatry to connect patients in rural areas with needed psychiatric care are freeing up EDs to focus on medical care. In just 11 months, 91 North Carolina hospitals have at least started the process to engage in NC-STeP. Much of the savings from NC-STeP come from involuntary commitment orders being overturned as a result of the telepsychiatry consults, reducing the need for expensive inpatient care. Implementing NC-STeP has involved multiple hurdles including credentialing difficulties and technical/firewall challenges. The Texas model provides 24/7 availability of psychiatrists via telemedicine through a network of MHECs. In-person staff at the MHECs perform basic screening tests and blood draws so that medical clearance can be achieved without the need for an ED visit in most cases. Funding for the MHECs comes from the state, hospitals in the region, and local governmental authorities that reap savings or benefits from the initiative.

    NASA ground and flight test activities aimed at the development of in-space construction techniques for the assembly of Space-Station-sized structures are described. In particular, attention is given to the EASE and ACCESS flight experiments, the ground and water tank program, and operations in-flight including instrumentations. The baseline experiments demonstrate that erectable structures can be assembled effectively by astronauts in EVA. The average assembly time for a 45-foot truss was 25.5 minutes; the assembly rate was 3.6 struts per minute.

    The Kennedy Space Center (KSC) Payload Management and Operations Directorate is responsible for the processing of Space Shuttle payloads. The KSC responsibilities begin prior to hardware arrival at the launch site and extend until the experiments are returned to the investigators after the flight. The KSC involvement with the integration and checkout of payloads begins with participation in experiment, Mission Peculiar Equipment (MPE), and integrated payload design reviews. This involvement also includes participation in assembly and testing of flight hardware at the appropriate design center, university, or private corporation. Once the hardware arrives at the launch site, KSC personnel install the experiments and MPE onto a carrier in the Operations and Checkout (O & C) building. Following integration, the payload is functionally tested and then installed into the orbiter. After the mission, the payload is removed from the orbiter, deintegrated in the O & C building, and the experiments are turned over to the mission manager. One of the many payloads process at KSC consisted of two space construction experiments: the Experimental Assembly of Structures in Extravehicular Activity (EASE) and the Assembly Concept for Construction of Erectable Space Structures (ACCESS). The details of EASE/ACCESS integration, testing, and deintegration are addressed and how this mission can serve as a guide for future space construction payloads is discussed.

  5. Ease of identifying words degraded by visual noise.

    PubMed

    Barber, P; de la Mahotière, C

    1982-08-01

    A technique is described for investigating word recognition involving the superimposition of 'noise' on the visual target word. For this task a word is printed in the form of letters made up of separate elements; noise consists of additional elements which serve to reduce the ease whereby the words may be recognized, and a threshold-like measure can be obtained in terms of the amount of noise. A word frequency effect was obtained for the noise task, and for words presented tachistoscopically but in conventional typography. For the tachistoscope task, however, the frequency effect depended on the method of presentation. A second study showed no effect of inspection interval on performance on the noise task. A word-frequency effect was also found in a third experiment with tachistoscopic exposure of the noise task stimuli in undegraded form. The question of whether common processes are drawn on by tasks entailing different ways of varying ease of recognition is addressed, and the suitability of different tasks for word recognition research is discussed.

  6. Weighted hurdle regression method for joint modeling of cardiovascular events likelihood and rate in the US dialysis population.

    2014-11-10

    We propose a new weighted hurdle regression method for modeling count data, with particular interest in modeling cardiovascular events in patients on dialysis. Cardiovascular disease remains one of the leading causes of hospitalization and death in this population. Our aim is to jointly model the relationship/association between covariates and (i) the probability of cardiovascular events, a binary process, and (ii) the rate of events once the realization is positive-when the 'hurdle' is crossed-using a zero-truncated Poisson distribution. When the observation period or follow-up time, from the start of dialysis, varies among individuals, the estimated probability of positive cardiovascular events during the study period will be biased. Furthermore, when the model contains covariates, then the estimated relationship between the covariates and the probability of cardiovascular events will also be biased. These challenges are addressed with the proposed weighted hurdle regression method. Estimation for the weighted hurdle regression model is a weighted likelihood approach, where standard maximum likelihood estimation can be utilized. The method is illustrated with data from the United States Renal Data System. Simulation studies show the ability of proposed method to successfully adjust for differential follow-up times and incorporate the effects of covariates in the weighting.

    The effect of pH reduction (from 6·30-6·45 to 4·22-4·46) and the addition of antimicrobial compounds (sodium benzoate and potassium sorbate) on the inhibition of Saccharomyces cerevisiae and Escherichia coli in prickly pear beverages formulated with the pulp and peel of Villanueva (V, Opuntia albicarpa) and Rojo Vigor (RV, Opuntia ficus-indica) varieties during 14 days of storage at 25°C, was evaluated. RV variety presented the highest microbial inhibition. By combining pH reduction and preservatives, reductions of 6·2-log10 and 2·3-log10 for E. coli and S. cerevisiae were achieved respectively. Due to the low reduction of S. cerevisiae, pulsed electric fields (PEF) (11-15 μs/25-50 Hz/27-36 kV cm(-1)) was applied as another preservation factor. The combination of preservatives, pH reduction and PEF at 13-15 μs/25-50 Hz for V variety, and 11 μs/50 Hz, 13-15 μs/25-50 Hz for RV, had a synergistic effect on S. cerevisiae inhibition, achieving at least 3·4-log10 of microbial reduction immediately after processing, and more than 5-log10 at fourth day of storage at 25°C maintained this reduction during 21 days of storage (P > 0·05). Hurdle technology using PEF in combination with other factors is adequate to maintain stable prickly pear beverages during 21 days/25°C. Significance and impact of the study: Prickly pear is a fruit with functional value, with high content of nutraceuticals and antioxidant activity. Functional beverages formulated with the pulp and peel of this fruit represent an alternative for its consumption. Escherichia coli and Saccharomyces cerevisiae are micro-organisms that typically affect fruit beverage quality and safety. The food industry is looking for processing technologies that maintain quality without compromising safety. Hurdle technology, including pulsed electric fields (PEF) could be an option to achieve this. The combination of PEF, pH reduction and preservatives is an alternative to obtain safe and minimally processed

  8. Palm: Easing the Burden of Analytical Performance Modeling

    2014-06-01

    Analytical (predictive) application performance models are critical for diagnosing performance-limiting resources, optimizing systems, and designing machines. Creating models, however, is difficult because they must be both accurate and concise. To ease the burden of performance modeling, we developed Palm, a modeling tool that combines top-down (human-provided) semantic insight with bottom-up static and dynamic analysis. To express insight, Palm defines a source code modeling annotation language. By coordinating models and source code, Palm's models are `first-class' and reproducible. Unlike prior work, Palm formally links models, functions, and measurements. As a result, Palm (a) uses functions to either abstract or express complexity (b) generates hierarchical models (representing an application's static and dynamic structure); and (c) automatically incorporates measurements to focus attention, represent constant behavior, and validate models. We discuss generating models for three different applications.

  9. Neutral Buoyancy Simulator-EASE Project (NB32)

    1980-01-01

    Once the United States' space program had progressed from Earth's orbit into outerspace, the prospect of building and maintaining a permanent presence in space was realized. To accomplish this feat, NASA launched a temporary workstation, Skylab, to discover the effects of low gravity and weightlessness on the human body, and also to develop tools and equipment that would be needed in the future to build and maintain a more permanent space station. The structures, techniques, and work schedules had to be carefully designed to fit this unique construction site. The components had to be lightweight for transport into orbit, yet durable. The station also had to be made with removable parts for easy servicing and repairs by astronauts. All of the tools necessary for service and repairs had to be designed for easy manipulation by a suited astronaut. Construction methods had to be efficient due to the limited time the astronauts could remain outside their controlled environment. In lieu of all the specific needs for this project, an environment on Earth had to be developed that could simulate a low gravity atmosphere. A Neutral Buoyancy Simulator (NBS) was constructed by NASA's Marshall Space Flight Center (MSFC) in 1968. Since then, NASA scientists have used this facility to understand how humans work best in low gravity and also provide information about the different kinds of structures that can be built. Pictured is a Massachusetts Institute of Technology (MIT) student working in a spacesuit on the Experimental Assembly of Structures in Extravehicular Activity (EASE) project which was developed as a joint effort between MFSC and MIT. The EASE experiment required that crew members assemble small components to form larger components, working from the payload bay of the space shuttle. The MIT student in this photo is assembling two six-beam tetrahedrons.

  10. A Spatial Poisson Hurdle Model for Exploring Geographic Variation in Emergency Department Visits

    2012-01-01

    Summary We develop a spatial Poisson hurdle model to explore geographic variation in emergency department (ED) visits while accounting for zero inflation. The model consists of two components: a Bernoulli component that models the probability of any ED use (i.e., at least one ED visit per year), and a truncated Poisson component that models the number of ED visits given use. Together, these components address both the abundance of zeros and the right-skewed nature of the nonzero counts. The model has a hierarchical structure that incorporates patient- and area-level covariates, as well as spatially correlated random effects for each areal unit. Because regions with high rates of ED use are likely to have high expected counts among users, we model the spatial random effects via a bivariate conditionally autoregressive (CAR) prior, which introduces dependence between the components and provides spatial smoothing and sharing of information across neighboring regions. Using a simulation study, we show that modeling the between-component correlation reduces bias in parameter estimates. We adopt a Bayesian estimation approach, and the model can be fit using standard Bayesian software. We apply the model to a study of patient and neighborhood factors influencing emergency department use in Durham County, North Carolina. PMID:23543242

    Novel plant genome editing techniques call for an updated legislation regulating the use of plants produced by genetic engineering or genome editing, especially in the European Union. Established more than 25 years ago and based on a clear distinction between transgenic and conventionally bred plants, the current EU Directives fail to accommodate the new continuum between genetic engineering and conventional breeding. Despite the fact that the Directive 2001/18/EC contains both process- and product-related terms, it is commonly interpreted as a strictly process-based legislation. In view of several new emerging techniques which are closer to the conventional breeding than common genetic engineering, we argue that it should be actually interpreted more in relation to the resulting product. A legal guidance on how to define plants produced by exploring novel genome editing techniques in relation to the decade-old legislation is urgently needed, as private companies and public researchers are waiting impatiently with products and projects in the pipeline. We here outline the process in the EU to develop a legislation that properly matches the scientific progress. As the process is facing several hurdles, we also compare with existing frameworks in other countries and discuss ideas for an alternative regulatory system.

    This study presents the application of regression shrinkage and artificial neural networks in predicting the results of 400-metres hurdles races. The regression models predict the results for suggested training loads in the selected three-month training period. The material of the research was based on training data of 21 Polish hurdlers from the Polish National Athletics Team Association. The athletes were characterized by a high level of performance. To assess the predictive ability of the constructed models a method of leave-one-out cross-validation was used. The analysis showed that the method generating the smallest prediction error was the LASSO regression extended by quadratic terms. The optimal model generated the prediction error of 0.59 s. Otherwise the optimal set of input variables (by reducing 8 of the 27 predictors) was defined. The results obtained justify the use of regression shrinkage in predicting sports outcomes. The resulting model can be used as a tool to assist the coach in planning training loads in a selected training period. PMID:28090147

    Combination of disparate as well as related antimicrobial effects constitutes the concept of hurdle technology. Quantification of combined effects, including claims of synergy, can be accomplished using surface response modelling, as is frequently done and reported. The Gamma hypothesis, however, states that the relative effects of different antimicrobial factors combine independently. Studies performed using time to detection have shown that the Gamma hypothesis is an adequate foundation for the analysis of multi-factor environmental stresses placed on microorganisms, including pH, weak acids and temperature. Data from the combined action of Na acetate and pH on Aeromonas hydrophila, Na acetate/pH , K sorbate/pH and combined Na acetate/K sorbate at pH 6.5, 6.0 and 5.5 on Escherichia coli and the combined action of Na acetate/pH and temperature on Enterobacter sakazakii were examined using nominal logistic modelling, response surface modelling (RS) and by using a Gamma model. The Gamma model can be used in a predictive manner unlike the RS models and the parameters of the RS models can be approximated from the fit of the Gamma model to the observed data. The expansion of the Gamma model explains the occurrence of the statistically significant cross terms of the RS polynomials. The emphasis within the literature of seeking interactions or synergies between environmental factors should be replaced with one emphasising the falsification of the Gamma approach. This can be done by examining the relative ratios of the gamma factors when in combination, but this also requires the use of appropriate functions to do this.

    2016-08-02

    Hematopoietic stem and progenitor cells (HSPCs) have great therapeutic potential because of their ability to both self-renew and differentiate. It has been proposed that, given their unique properties, a small number of genetically modified HSPCs could accomplish lifelong, corrective reconstitution of the entire hematopoietic system in patients with various hematologic disorders. Scientists have demonstrated that gene addition therapies-targeted to HSPCs and using integrating retroviral vectors-possess clear clinical benefits in multiple diseases, among them immunodeficiencies, storage disorders, and hemoglobinopathies. Scientists attempting to develop clinically relevant gene therapy protocols have, however, encountered a number of unexpected hurdles because of their incomplete knowledge of target cells, genomic control, and gene transfer technologies. Targeted gene-editing technologies using engineered nucleases such as ZFN, TALEN, and/or CRISPR/Cas9 RGEN show great clinical promise, allowing for the site-specific correction of disease-causing mutations-a process with important applications in autosomal dominant or dominant-negative genetic disorders. The relative simplicity of the CRISPR/Cas9 system, in particular, has sparked an exponential increase in the scientific community's interest in and use of these gene-editing technologies. In this minireview, we discuss the specific applications of gene-editing technologies in human HSPCs, as informed by prior experience with gene addition strategies. HSPCs are desirable but challenging targets; the specific mechanisms these cells evolved to protect themselves from DNA damage render them potentially more susceptible to oncogenesis, especially given their ability to self-renew and their long-term proliferative potential. We further review scientists' experience with gene-editing technologies to date, focusing on strategies to move these techniques toward implementation in safe and effective clinical trials.

    Owing to its easy-to-use and multiplexing nature, the genome editing tool CRISPR-Cas9 (clustered regularly interspaced short palindromic repeats (CRISPR) associated nuclease 9) is revolutionizing many areas of medical research and one of the most amazing areas is its gene therapy potentials. Previous explorations into the therapeutic potentials of CRISPR-Cas9 were mainly conducted in vitro or in animal germlines, the translatability of which, however, is either limited (to tissues with adult stem cells amenable to culture and manipulation) or currently impermissible (due to ethic concerns). Recently, important progresses have been made on this regard. Several studies have demonstrated the ability of CRISPR-Cas9 for in vivo gene therapy in adult rodent models of human genetic diseases delivered by methods that are potentially translatable to human use. Although these recent advances represent a significant step forward to the eventual application of CRISPR-Cas9 to the clinic, there are still many hurdles to overcome, such as the off-target effects of CRISPR-Cas9, efficacy of homology-directed repair, fitness of edited cells, immunogenicity of therapeutic CRISPR-Cas9 components, as well as efficiency, specificity, and translatability of in vivo delivery methods. In this article, we introduce the mechanisms and merits of CRISPR-Cas9 in genome editing, briefly retrospect the applications of CRISPR-Cas9 in gene therapy explorations and highlight recent advances, later we discuss in detail the challenges lying ahead in the way of its translatability, propose possible solutions, and future research directions.

    This paper describes a technique which reproducibly quantifies the ease of removal of microorganisms from surfaces. Tiles (22 mm x 22 mm) of various materials were colonised with Staphylococcus epidermidis NCTC 11047, Escherichia coli K12 HB101 or Pseudomonas aeruginosa PaWH, by submersion, for various times (2 min-48 h), in inoculated Tryptone Soya broth (37 degrees C). Colonised tiles were blotted onto a Tryptone Soya agar plate for 1 min and the process was repeated through a succession of agar plates. The final plate contained tetrazolium salts (0.05% w/v) and was incubated in situ with the tile. Tetrazolium plates indicated that very few organisms remained on the tiles after 15 successive blots. In all instances, the number of recovered colonies per plate decreased exponentially with plate succession number, according to the relationship, CFU = A.10-kN, where CFU is the number of colonies transferred, k is the removal exponent, A is the intercept and N is the plate succession number. Removal exponents differed significantly between organisms (P > 0.95), depended on the nature of the test surface, and decreased as the inital attachment and colonisation time was increased from 2 min-48 h. Intercept values (A) but not the gradients were dependent upon the initial numbers of bacteria in suspension. These data indicate that the gradients derived from counting recoverable viable cells from successive blots of test tiles onto agar is a measure of the strength of attachment of the organisms to the surface.

    INTRODUCTION Discovery of abdominal masses often poses significant diagnostic difficulties. GISTs are mesenchymal masses, with specific histological features. Dimensions may vary from millimeters to giant tumours. We would like to present our case, which had an unexpectedly easy operative course which was easily handled with a simple surgical excision with a short operative duration. PRESENTATION OF CASE A 38 years old female patient was diagnosed to have an abdominal heterogen mass of 15 cm × 12 cm × 10 cm in dimension. Abdominal computed tomography revealed the solid mass between the stomach and pancreas corpus and tail, possibly orginating from the pancreas. With the preoperative diagnosis of locally invasive distal pancreas cancer the patient underwent laparotomy, following the dissection, the mass was observed to be originating from the posterior gastric Wall, extending exophytically with a peduncle of 5 cm in width, without any visual evidence for peritoneal invasion and metastasis. The tumour and the peduncle was resected with stapler device. Total operation time was 30 min. Postoperative course was uneventful. Pathologic diagnosis was gastrointestinal stromal tumour (GIST). DISCUSSION Pedunculated large GISTs are not frequent and they can enlarge as 15 cm in diameter and compress the neighbouring organs. When they were huge, it is difficult to differentiate the origin of the masses. GISTs should be considered in differential diagnosis of giant abdominal masses. CONCLUSION When GISTs are huge and pedunculated, it can be difficult to differentiate the origin of the masses. This case report presents unexpectedly ease surgery for a worrysome abdominal mass.

    ABSTRACT- We demonstrate that merely naming a research finding elicits feelings of ease (a "name-ease" effect). These feelings of ease can reduce or enhance the finding's perceived importance depending on whether people are making inferences about how understandable or how memorable the finding is. When people assess their understanding of a finding, feelings of ease reduce the finding's perceived importance. This is because people usually invest effort to understand important information but also mistakenly infer the reverse-namely, that information that requires effort to be understood is important. In contrast, when people assess the memorability of a finding, feelings of ease increase the finding's perceived importance. Because people usually recall important information easily, in this case they equate ease with importance. Psychological effects, economic principles, math theorems, jury cases, and decisions to fund medical research can all show these effects.

    Importance While progress continues to be made in the field of stem cell regenerative medicine for the treatment of cardiovascular disease, significant barriers to clinical translation still exist that have thwarted the delivery of cell therapy to the bedside. Objective The purpose of this review is to summarize the major current hurdles for the clinical implementation of stem cell therapy and discuss potential strategies to overcome them. Evidence Review Information for this review was obtained through a search of PubMed and the Cochrane database for English language studies published between January 1, 2000 and June 15, 2016. Ten randomized clinical trials and eight systematic reviews were included in this review. Findings One of the major clinical hurdles facing the routine implementation of stem cell therapy is the limited and inconsistent benefit observed thus far. Reasons for this are unclear but may be due to poor cell retention and survival, as suggested by numerous preclinical studies and a handful of human studies incorporating cell fate imaging. Additional cell fate imaging studies in humans are needed to determine how these factors contribute to limited efficacy. Treatment strategies to address poor cell retention and survival are under investigation and include the following: 1) co-administering of immunosuppressive and pro-survival agents, 2) delivering cardioprotective factors packaged in exosomes rather than the cells themselves, and 3) using tissue engineering strategies to provide structural support for cells. If larger grafts are achieved using the aforementioned strategies, it will be imperative to carefully monitor the potential risks of tumorigenicity, immunogenicity, and arrhythmogenicity. Conclusions and Relevance Despite important achievements to date, stem cell therapy is not yet ready for routine clinical implementation. Significant research is still needed to address the clinical hurdles outlined herein before the next wave of large

    At present, the ease of subdivision of scored tablets is estimated in vivo. In order to replace such in vivo testing and to develop a surrogate test which uses in vitro techniques, the association between physical parameters of scored tablets and their ease of subdivision was studied. The physical properties of 23 brands of scored tablets of which their ease of subdivision in vivo was known were established. Statistical modeling using a logistic regression model was used to fit the data and estimate the contribution of each physical parameter to the goodness of the fit. For scored oblong tablets, the critical parameters for their ease of subdivision are: diameter; diameter/width ratio; depth of score line and resistance to crushing. Criteria for each of these parameters were derived. All criteria need to be complied with to guarantee sufficient ease of subdivision of scored oblong tablets. For scored round tablets the critical parameters, in decreasing order of importance, for their ease of subdivision, are: resistance to crushing, diameter, score mark (one- or two-sided), and shape (flat or biconvex). A five-parameter predictive model was developed, showing excellent discrimination. For development, the proposed surrogate tests are sufficiently reliable. For release testing and stability studies, resistance to crushing of a scored tablet is a reliable predictor of its ease of subdivision.

    The Marshall Space Flight Center (MSFC) Spacelab Payload Project Office was responsible for the mission management and development of several successful payloads. Two recent space construction experiments, the Experimental Assembly of Structures in Extravehicular Activity (EASE) and the Assembly Concept for Construction of Erectable Space Structures (ACCESS), were combined into a payload managed by the center. The Ease/ACCESS was flown aboard the Space Shuttle Mission 61-B. The EASE/ACCESS experiments were the first structures assembled in space, and the method used to manage this successful effort will be useful for future space construction missions. The MSFC mission management responsibilities for the EASE/ACCESS mission are addressed and how the lessons learned from the mission can be applied to future space construction projects are discussed.

  11. Emergent properties define the subjective nature of health and dis-ease.

    PubMed

    Sturmberg, Joachim P

    2014-08-01

    Health and dis-ease by their etymological origins refer to an evaluative, not objective, state. Health is an adaptive state, constantly reestablishing itself through interactions between the many biological, social, emotional, and cognitive factors in a person's life. Such adaptive processes define health as an emergent state. Outcomes of emergent phenomena are not precisely predictable and reside in a phase space that contains all possible states ranging from perfect to poor health states, the latter reflecting dis-ease. However, we have seen a migration of meaning from the subjective, dis-ease, to the objective, disease, referring to uniquely identifiable biomedical change. Clinical reality though teaches us that many experiences of dis-ease are not associated with any objective abnormality, an insight with important implications for clinical care and health policy.

  14. Exploring hurdles to transfer : student experiences of applying knowledge across disciplines

    NASA Astrophysics Data System (ADS)

    Lappalainen, Jouni; Rosqvist, Juho

    2015-04-01

    This paper explores the ways students perceive the transfer of learned knowledge to new situations - often a surprisingly difficult prospect. The novel aspect compared to the traditional transfer studies is that the learning phase is not a part of the experiment itself. The intention was only to activate acquired knowledge relevant to the transfer target using a short primer immediately prior to the situation where the knowledge was to be applied. Eight volunteer students from either mathematics or computer science curricula were given a task of designing an adder circuit using logic gates: a new context in which to apply knowledge of binary arithmetic and Boolean algebra. The results of a phenomenographic classification of the views presented by the students in their post-experiment interviews are reported. The degree to which the students were conscious of the acquired knowledge they employed and how they applied it in a new context emerged as the differentiating factors.

    Preservative factors act as hurdles against microorganisms by inhibiting their growth; these are essential control measures for particular food-borne pathogens. Different combinations of hurdles can be quantified and compared to each other in terms of their inhibitory effect (“iso-hurdle”). We present here a methodology for establishing microbial iso-hurdle rules in three steps: (i) developing a predictive model based on existing but disparate data sets, (ii) building an experimental design focused on the iso-hurdles using the model output, and (iii) validating the model and the iso-hurdle rules with new data. The methodology is illustrated with Listeria monocytogenes. Existing data from industry, a public database, and the literature were collected and analyzed, after which a total of 650 growth rates were retained. A gamma-type model was developed for the factors temperature, pH, aw, and acetic, lactic, and sorbic acids. Three iso-hurdle rules were assessed (40 logcount curves generated): salt replacement by addition of organic acids, sorbic acid replacement by addition of acetic and lactic acid, and sorbic acid replacement by addition of lactic/acetic acid and salt. For the three rules, the growth rates were equivalent in the whole experimental domain (γ from 0.1 to 0.5). The lag times were also equivalent in the case of mild inhibitory conditions (γ ≥ 0.2), while they were longer in the presence of salt than acids under stress conditions (γ < 0.2). This methodology allows an assessment of the equivalence of inhibitory effects without intensive data generation; it could be applied to develop milder formulations which guarantee microbial safety and stability.

    Three experiments tested the hypothesis of implicit associations between happiness and the performance ease concept and between sadness and the performance difficulty concept. All three studies applied a sequential priming paradigm: participants categorized emotion words (Experiment 1) or facial expressions (Experiment 2) as positive or negative or as referring to ease or difficulty (Experiment 3). These targets were preceded by briefly flashed ease- or difficulty-related words or neutral non-words (Experiments 1 and 2) or by happy, sad, or neutral facial expressions (Experiment 3) as primes. As predicted, all three experiments revealed increases in reaction times in the sequential priming task from congruent trials (happiness/ease and sadness/difficulty) over neutral trials to incongruent trials (sadness/ease and happiness/difficulty). The findings provide evidence for implicit associative links of happiness with ease and sadness with difficulty, as posited by the implicit-affect-primes-effort model (Gendolla, Int J Psychophysiol 86:123-135, 2012; Soc Pers Psychol Compass 9:606-619, 2015).

  17. Comparison of measured dermal dust exposures with predicted exposures given by the EASE expert system.

    PubMed

    Hughson, Graeme W; Cherrie, John W

    2005-03-01

    Estimation and Assessment of Substance Exposure (EASE) is a rule-based computer expert system used by regulatory authorities within the European Union to assist in assessing exposure for both new and existing substances. It can provide estimates of both inhalation exposure levels and dermal exposure levels to the hands and forearms. This article describes the results of a study in which measurements of workplace dermal zinc exposures were collected for an industry-wide risk assessment and also compared with the levels predicted by EASE. Measurements were obtained from subjects in seven different workplaces that were producing or working with zinc metal or zinc compounds. The work activities were grouped a priori into one of three categories used by EASE for dermal exposure assessment: 'non-dispersive use with intermittent direct handling', 'wide dispersive use with intermittent direct handling' and 'wide dispersive use with extensive direct handling'. The predicted exposure ranges for these categories are 0.1-1, 1-5 and 5-15 mg cm(-2) day(-1). Although the average measured exposure levels for each of the categories increased in line with the predictions from EASE, the model overestimated dermal exposure to the hands by a factor of approximately 50 when the mid-point of the EASE range was compared with the measured mean exposure. Furthermore, a significant additional exposure was found on other parts of the workers' bodies for which EASE does not provide any estimates. Interpretation of the dermal exposure data was complicated by the use of protective gloves, which might have limited the amount of zinc dust adhering to the workers' skin. However, observation of the work activities suggested that the pattern of glove use was such that they would not provide a consistent level of protection. This study provided an opportunity to collect a large amount of dermal zinc exposure data for risk assessment purposes and also enabled a dermal sampling method to be developed

    High rates of nonmedical exemptions (NMEs) from required childhood vaccinations have contributed to outbreaks of vaccine-preventable diseases, such as measles and pertussis. Understanding the parental decision to obtain an NME could help health professionals and public health programs improve vaccination rates in areas with high vaccine refusal. Using a 2002-2003 multi-state survey of parents of school age children (​n=2445), this study found that parental distrust of the government and of healthcare providers is a significant factor related to a number of vaccine-related beliefs and behaviors. The odds that parents who distrust the government have seen a complementary/alternative medicine (CAM) provider were 2.11 times greater than those of parents who trust the government (70.1% vs 52.6%; OR, 2.11; 95% CI, 1.59-2.84; P<0.01). Parents who distrust the government had increased odds of trusting vaccine information from CAM providers compared to trusting parents (57.9% vs 46.3%; OR, 1.53; 95% CI, 1.16-2.01; P<0.01). Parents who distrust the government also had increased odds of distrusting vaccine information acquired at their healthcare providers' offices (12.6% vs 4.7%; OR, 2.64; 95% CI, 1.64-4.24; P<0.01). Distrustful parents had increased odds of thinking government sources of information about vaccines were unreliable, categorizing the CDC, the Food and Drug Administration (FDA), or local and state health departments as poor or very poor sources (distrust government vs trust government: 25.2% vs 11.7%; OR, 2.39; 95% CI, 1.70-3.36; P<0.01; distrust healthcare providers vs trust healthcare providers: 24.4% vs 11.4%; OR, 2.44; 95% CI, 1.75-3.38; P<0.01). These findings indicate that distrustful parent populations may need to be reached through modalities outside of traditional government and healthcare provider communications. Research into new and more effective techniques for delivering pro-vaccine messages is warranted.

    The Tissue Engineering and Regenerative Medicine International Society of the Americas (TERMIS-AM) Industry Committee conducted a semiquantitative opinion survey in 2010 to delineate potential hurdles to commercialization perceived by the TERMIS constituency groups that participate in the stream of technology commercialization (academia, start-up companies, development-stage companies, and established companies). A significant hurdle identified consistently by each group was access to capital for advancing potential technologies into development pathways leading to commercialization. A follow-on survey was developed by the TERMIS-AM Industry Committee to evaluate the financial industry's perspectives on investing in regenerative medical technologies. The survey, composed of 15 questions, was developed and provided to 37 investment organizations in one of three sectors (governmental, private, and public investors). The survey was anonymous and confidential with sector designation the only identifying feature of each respondent's organization. Approximately 80% of the survey was composed of respondents from the public (n=14) and private (n=15) sectors. Each respondent represents one investment organization with the potential of multiple participants participating to form the organization's response. The remaining organizations represented governmental agencies (n=8). Results from this survey indicate that a high percentage (<60%) of respondents (governmental, private, and public) were willing to invest >$2MM into regenerative medical companies at the different stages of a company's life cycle. Investors recognized major hurdles to this emerging industry, including regulatory pathway, clinical translation, and reimbursement of these new products. Investments in regenerative technologies have been cyclical over the past 10-15 years, but investors recognized a 1-5-year investment period before the exit via Merger and Acquisition (M&A). Investors considered

    2006-02-01

    This study evaluated the glucose tolerance of acetic acid bacteria strains isolated from Traditional Balsamic Vinegar. The results showed that the greatest hurdle to acetic acid bacteria growth is the high sugar concentration, since the majority of the isolated strains are inhibited by 25% of glucose. Sugar tolerance is an important technological trait because Traditional Balsamic Vinegar is made with concentrated cooked must. On the contrary, ethanol concentration of the cooked and fermented must is less significant for acetic acid bacteria growth. A tentative identification of the isolated strains was done by 16S-23S-5S rDNA PCR/RFLP technique and the isolated strains were clustered: 32 strains belong to Gluconacetobacter xylinus group, two strains to Acetobacter pasteurianus group and one to Acetobacter aceti.

  1. Does aging influence people's metacomprehension? Effects of processing ease on judgments of text learning.

    PubMed

    2006-06-01

    In 2 experiments, the authors investigated whether age-related differences exist in metacomprehension by evaluating predictions based on the ease-of-processing (EOP) hypothesis. According to this hypothesis, judgments of how well a text has been learned are based on how easily each text was processed; easier processing results in higher judgments. Participants read either sentence pairs or longer texts and judged their learning of each immediately afterward. Although an age-related difference in the use of processing ease in judgments was observed with sentence pairs, for longer texts older and younger adults' judgments were similarly related to processing ease. In both experiments, age equivalence was also evident in the accuracy of the judgments at predicting performance on the criterion test. The overall pattern of results suggests that judging text learning remains largely intact with aging.

    To evaluate the flow hemodynamics of the TrapEase vena cava filter using three dimensional computational fluid dynamics, including simulated thrombi of multiple shapes, sizes, and trapping positions. The study was performed to identify potential areas of recirculation and stagnation and areas in which trapped thrombi may influence intrafilter thrombosis. Computer models of the TrapEase filter, thrombi (volumes ranging from 0.25mL to 2mL, 3 different shapes), and a 23mm diameter cava were constructed. The hemodynamics of steady-state flow at Reynolds number 600 was examined for the unoccluded and partially occluded filter. Axial velocity contours and wall shear stresses were computed. Flow in the unoccluded TrapEase filter experienced minimal disruption, except near the superior and inferior tips where low velocity flow was observed. For spherical thrombi in the superior trapping position, stagnant and recirculating flow was observed downstream of the thrombus; the volume of stagnant flow and the peak wall shear stress increased monotonically with thrombus volume. For inferiorly trapped spherical thrombi, marked disruption to the flow was observed along the cava wall ipsilateral to the thrombus and in the interior of the filter. Spherically shaped thrombus produced a lower peak wall shear stress than conically shaped thrombus and a larger peak stress than ellipsoidal thrombus. We have designed and constructed a computer model of the flow hemodynamics of the TrapEase IVC filter with varying shapes, sizes, and positions of thrombi. The computer model offers several advantages over in vitro techniques including: improved resolution, ease of evaluating different thrombus sizes and shapes, and easy adaptation for new filter designs and flow parameters. Results from the model also support a previously reported finding from photochromic experiments that suggest the inferior trapping position of the TrapEase IVC filter leads to an intra-filter region of recirculating

  4. Identification of a short region on chromosome 6 affecting direct calving ease in Piedmontese cattle breed.

    Calving in cattle is affected by calf morphology and by dam characteristics. It is described by two different traits: maternal calving ease, which is the ability to generate dams with good physiological predisposition to calving, and direct calving ease, which is the ability to generate calves that are easily born. The aim of this study was to identify regions of cattle genome harboring genes possibly affecting direct calving ease in the Piedmontese cattle breed. A population of 323 bulls scored for direct calving ease (EBV) was analyzed by a medium-density SNP marker panel (54,001 SNPs) to perform a genome-wide scan. The strongest signal was detected on chromosome 6 between 37.8 and 38.7 Mb where 13 SNPs associated to direct calving ease were found. Three genes are located in this region: LAP3, encoding for a leucine aminopeptidase involved in the oxytocin hydrolysis; NCAPG, encoding for a non-SMC condensin I complex, which has been associated in cattle with fetal growth and carcass size; and LCORL, which has been associated to height in humans and cattle. To further confirm the results of the genome-wide scan we genotyped additional SNPs within these genes and analyzed their association with direct calving ease. The results of this additional analysis fully confirmed the findings of the GWAS and particularly indicated LAP3 as the most probable gene involved. Linkage Disequilibrium (LD) analysis showed high correlation between SNPs located within LAP3 and LCORL indicating a possible selection signature due either to increased fitness or breeders' selection for the trait.

    WebEase (Epilepsy Awareness, Support, and Education) is an online epilepsy self-management program to assist people with taking medication, managing stress, and improving sleep quality. The primary study aims were to determine if those who participated in WebEase demonstrated improvements in medication adherence, perceived stress, and sleep quality. Participants were randomized to a treatment (T) or waitlist control (WCL) group (n=148). At follow-up, participants in the T group reported higher levels of medication adherence than those in the WLC group. Analyses were also conducted comparing those who had completed WebEase modules with those who had not. Those who had completed at least some modules within the WebEase program reported higher levels of self-efficacy and a trend toward significance was observed for the group×time interactions for medication adherence, perceived stress, self-management, and knowledge. The results highlight the usefulness of online tools to support self-management among people with epilepsy.

    2015-01-01

    Introduction Ease of access to substances has been shown to have a direct and significant relationship with substance use for school-aged children. Previous research involving rural samples of middle and high school students reveals that perceived ease of access to substances is a significant predictor of recent use among rural adolescents; however, it is unclear if perceived access to substances varies between rural and urban areas. The purpose of the current study was to examine rural-urban differences in perceived ease of access to alcohol, smoking and chewing tobacco, marijuana, and seven other substances in order to better inform and promote future substance use prevention and programming efforts in rural areas. Methods Data were analyzed from the 2013 Georgia Student Health Survey II, administered in all public and interested private/charter schools in the state of Georgia. A total of 513,909 students (18.2% rural) indicated their perceived ease of access to 11 substances on a 4-point Likert-type scale. Rural-urban differences were investigated using chi-square analysis. Results In general, it appeared the rural-urban differences fell along legal/illicit lines. For middle school students, a significant difference in perceived ease of access was found for each substance, with rural students reporting greater access to smoking tobacco, chewing tobacco, and steroids, and urban students reporting greater access to alcohol, marijuana, cocaine, inhalants, ecstasy, methamphetamine, hallucinogens, and prescription drugs. Rural high school students reported higher access to alcohol, smoking tobacco, chewing tobacco, and steroids, with urban students reporting higher access to marijuana, cocaine, inhalants, ecstasy, and hallucinogens. Perceptions of ease of access more than doubled for each substance in both geographies between middle and high school. Conclusions In summary, the current study found multiple and fairly consistent differences between rural and urban

    The study aims to provide an ease-of-use approach for senior patients to utilize remote healthcare systems. An ease-of-use remote healthcare system (RHS) architecture using RFID (Radio Frequency Identification) and networking technologies is developed. Specifically, the codes in RFID tags are used for authenticating the patients' ID to secure and ease the login process. The patient needs only to take one action, i.e. placing a RFID tag onto the reader, to automatically login and start the RHS and then acquire automatic medical services. An ease-of-use emergency monitoring and reporting mechanism is developed as well to monitor and protect the safety of the senior patients who have to be left alone at home. By just pressing a single button, the RHS can automatically report the patient's emergency information to the clinic side so that the responsible medical personnel can take proper urgent actions for the patient. Besides, Web services technology is used to build the Internet communication scheme of the RHS so that the interoperability and data transmission security between the home server and the clinical server can be enhanced. A prototype RHS is constructed to validate the effectiveness of our designs. Testing results show that the proposed RHS architecture possesses the characteristics of ease to use, simplicity to operate, promptness in login, and no need to preserve identity information. The proposed RHS architecture can effectively increase the willingness of senior patients who act slowly or are unfamiliar with computer operations to use the RHS. The research results can be used as an add-on for developing future remote healthcare systems.

    Antimicrobial stewardship is used to combat antimicrobial resistance. In Singapore, a tertiary hospital has integrated a computerised decision support system, called Antibiotic Resistance Utilisation and Surveillance-Control (ARUSC), into the electronic inpatient prescribing system. ARUSC is launched either by the physician to seek guidance for an infectious disease condition or via auto-trigger when restricted antibiotics are prescribed. This paper describes the implementation of ARUSC over three phases from 1 May 2011 to 30 April 2013, compared factors between ARUSC launches via auto-trigger and for guidance, examined factors associated with acceptance of ARUSC recommendations, and assessed user acceptability. During the study period, a monthly average of 9072 antibiotic prescriptions was made, of which 2370 (26.1%) involved ARUSC launches. Launches via auto-trigger comprised 48.1% of ARUSC launches. In phase 1, 23% of ARUSC launches were completed. This rose to 38% in phase 2, then 87% in phase 3, as escapes from the ARUSC programme were sequentially disabled. Amongst completed launches for guidance, 89% of ARUSC recommendations were accepted versus 40% amongst completed launches via auto-trigger. Amongst ARUSC launches for guidance, being from a medical department [adjusted odds ratio (aOR)=1.20, 95% confidence interval (CI) 1.04-1.37] and ARUSC launch during on-call (aOR=1.81, 95% CI 1.61-2.05) were independently associated with acceptance of ARUSC recommendations. Junior physicians found ARUSC useful. Senior physicians found ARUSC reliable but admitted to having preferences for antibiotics that may conflict with ARUSC. Hospital-wide implementation of ARUSC encountered hurdles from physicians. With modifications, the completion rate improved.

  1. Understanding traditional African healing

    Traditional African healing has been in existence for many centuries yet many people still seem not to understand how it relates to God and religion/spirituality. Some people seem to believe that traditional healers worship the ancestors and not God. It is therefore the aim of this paper to clarify this relationship by discussing a chain of communication between the worshipers and the Almighty God. Other aspects of traditional healing namely types of traditional healers, training of traditional healers as well as the role of traditional healers in their communities are discussed. In conclusion, the services of traditional healers go far beyond the uses of herbs for physical illnesses. Traditional healers serve many roles which include but not limited to custodians of the traditional African religion and customs, educators about culture, counselors, social workers and psychologists.

    This study presents findings of a mixed-method descriptive exploration of the role of friends and spirituality/religiosity in easing the burden of families with the rare inherited disorder, Li-Fraumeni Syndrome (LFS). LFS is caused by germline mutations in the TP53 gene and is associated with very high lifetime risk of developing one or more malignancies. During the first clinical visit we assessed several types of social support among a subset of study participants (N = 66) using an established interactive research tool called the Colored Eco-Genetic Relationship Map (CEGRM). We performed both quantitative and qualitative analyses of social relationships with LFS family members and close non-kin. Distress scores (N = 59) were mostly low normal, with some outliers. We found that reported friendships varied widely, that the friendships were often deep and enduring, and were important sources of informational, tangible, emotional and spiritual support. Confidantes tended to be best friends and/or spouses. Organized religion was important in selected families, typically from mainstream traditions. However, a number of people identified themselves as "spiritual" and reported spiritual and humanist explorations. Our results shed preliminary light on how some people in families with LFS cope in the face of tremendous medical, social and emotional challenges.

  3. Interset: A natural language interface for teleoperated robotic assembly of the EASE space structure

    A teleoperated robot was used to assemble the Experimental Assembly of Structures in Extra-vehicular activity (EASE) space structure under neutral buoyancy conditions, simulating a telerobot performing structural assembly in the zero gravity of space. This previous work used a manually controlled teleoperator as a test bed for system performance evaluations. From these results several Artificial Intelligence options were proposed. One of these was further developed into a real time assembly planner. The interface for this system is effective in assembling EASE structures using windowed graphics and a set of networked menus. As the problem space becomes more complex and hence the set of control options increases, a natural language interface may prove to be beneficial to supplement the menu based control strategy. This strategy can be beneficial in situations such as: describing the local environment, maintaining a data base of task event histories, modifying a plan or a heuristic dynamically, summarizing a task in English, or operating in a novel situation.

  4. Ease of Retrieval Effects on Relationship Commitment: The Role of Future Plans.

    How do perceptions of future romantic plans affect close relationships? In three studies, we examined the effects of ease of retrieval of future plans on romantic relationship commitment. We hypothesized that greater ease of retrieval would be associated with greater relationship commitment among those who were high in need for cognition. Study 1 participants listed either two or 10 future plans and completed a measure assessing need for cognition. Results showed that high need for cognition individuals asked to list two instead of 10 future plans reported greater commitment, but those low in need for cognition showed the opposite pattern. Study 2 replicated this effect while controlling for plan substitutability. Study 3 examined the mediational role of commitment doubt. Those high in need for cognition listing more plans had more doubts and reported lower commitment. These findings suggest that perceptions of future plans can influence relationship commitment under specific conditions.

    When perception by touch is couched in terms of movement, perception of heaviness can be understood as perception of difficulty to move. This experiment further investigated this proposal as well as the corollary proposal that perception of lightness may be understood as perception of ease to move. Blindfolded participants wielded weighted objects and rated how heavy or light each object felt and how difficult or easy each object was to move. Ratings of heaviness and difficulty to move were analogously constrained by movement-relevant variables. Ratings of lightness and ease-to-move were also analogously constrained by such variables, but in the opposite manner. Conventional descriptors such as heaviness or lightness may be inappropriate for a principled understanding of perception by touch.

    The objective of this study was to determine if ultraviolet germicidal irradiation (UVGI), moist heat incubation (MHI), or microwave-generated steam (MGS) decontamination affects the fitting characteristics, odor, comfort, or donning ease of six N95 filtering facepiece respirator (FFR) models. For each model, 10 experienced test subjects qualified for the study by passing a standard OSHA quantitative fit test. Once qualified, each subject performed a series of fit tests to assess respirator fit and completed surveys to evaluate odor, comfort, and donning ease with FFRs that were not decontaminated (controls) and with FFRs of the same model that had been decontaminated. Respirator fit was quantitatively measured using a multidonning protocol with the TSI PORTACOUNT Plus and the N95 Companion accessory (designed to count only particles resulting from face to face-seal leakage). Participants' subjective appraisals of the respirator's odor, comfort, and donning ease were captured using a visual analog scale survey. Wilcoxon signed rank tests compared median values for fit, odor, comfort, and donning ease for each FFR and decontamination method against their respective controls for a given model. Two of the six FFRs demonstrated a statistically significant reduction (p < 0.05) in fit after MHI decontamination. However, for these two FFR models, post-decontamination mean fit factors were still ≥ 100. One of the other FFRs demonstrated a relatively small though statistically significant increase (p < 0.05) in median odor response after MHI decontamination. These data suggest that FFR users with characteristics similar to those in this study population would be unlikely to experience a clinically meaningful reduction in fit, increase in odor, increase in discomfort, or increased difficulty in donning with the six FFRs included in this study after UVGI, MHI, or MGS decontamination. Further research is needed before decontamination of N95 FFRs for purposes of reuse can be

    2015-10-01

    Studies on rhetorical features of language have reported both enhancing and adverse effects on ease of processing. We hypothesized that two explanations may account for these inconclusive findings. First, the respective gains and losses in ease of processing may apply to different dimensions of language processing (specifically, prosodic and semantic processing) and different types of fluency (perceptual vs. conceptual) and may well allow for an integration into a more comprehensive framework. Second, the effects of rhetorical features may be sensitive to interactions with other rhetorical features; employing a feature separately or in combination with others may then predict starkly different effects. We designed a series of experiments in which we expected the same rhetorical features of the very same sentences to exert adverse effects on semantic (conceptual) fluency and enhancing effects on prosodic (perceptual) fluency. We focused on proverbs that each employ three rhetorical features: rhyme, meter, and brevitas (i.e., artful shortness). The presence of these target features decreased ease of conceptual fluency (semantic comprehension) while enhancing perceptual fluency as reflected in beauty and succinctness ratings that were mainly driven by prosodic features. The rhetorical features also predicted choices for persuasive purposes, yet only for the sentence versions featuring all three rhetorical features; the presence of only one or two rhetorical features had an adverse effect on the choices made. We suggest that the facilitating effects of a combination of rhyme, meter, and rhetorical brevitas on perceptual (prosodic) fluency overcompensated for their adverse effects on conceptual (semantic) fluency, thus resulting in a total net gain both in processing ease and in choices for persuasive purposes.

    This map shows the relative ease (or difficulty) with which rocks and surficial deposits can be excavated. Because of rapidly changing technology of excavation and considerable local variability of many rock units, it is not practical to specifically categorize rock units according to type of equipment needed for their excavations. However, it may be stated in general that rock units classed as very easy and easy can in most places be excavated by hand tools and by light machinery such as backhoes and small bulldozers; units included in easy to difficult require blasting and (or) heavy machinery such as rippers and large bulldozers for resistant rocks, and hand tools or light power equipment for soft rocks; and units classes as difficult and very difficult probably require blasting and heavy machinery.The excavation units shown here are based on map units of the geologic map of the Salina quadrangle. Where bedrock is mantled with thin unmapped surficial deposits, ease of excavation shown is that of the bedrock, not that of the thin surficial mantle; where surficial deposits are mapped, ease of excavation shown is that of surficial deposits.

    2015-01-01

    The present study investigated how ease of imagery influences source monitoring accuracy. Two experiments were conducted in order to examine how ease of imagery influences the probability of source confusions of perceived and imagined completions of natural symmetric shapes. The stimuli consisted of binary pictures of natural objects, namely symmetric pictures of birds, butterflies, insects, and leaves. The ease of imagery (indicating the similarity of the sources) and the discriminability (indicating the similarity of the items) of each stimulus were estimated in a pretest and included as predictors of the memory performance for these stimuli. It was found that confusion of the sources becomes more likely when the imagery process was relatively easy. However, if the different processes of source monitoring-item memory, source memory and guessing biases-are disentangled, both experiments support the assumption that the effect of decreased source memory for easily imagined stimuli is due to decision processes and misinformation at retrieval rather than encoding processes and memory retention. The data were modeled with a Bayesian hierarchical implementation of the one high threshold source monitoring model.

    2015-01-01

    On-demand mobility (ODM) through aviation refers to the ability to quickly and easily move people or equivalent cargo without delays introduced by lack of, or infrequently, scheduled service. A necessary attribute of ODM is that it be easy to use, requiring a minimum of special training, skills, or workload. Fully-autonomous vehicles would provide the ultimate in ease-of-use (EU) but are currently unproven for safety-critical applications outside of a few, situationally constrained applications (e.g. automated trains operating in segregated systems). Applied to aviation, the current and near-future state of the art of full-autonomy, may entail undesirable trade-offs such as very conservative operational margins resulting in reduced trip reliability and transportation utility. Furthermore, acceptance by potential users and regulatory authorities will be challenging without confidence in autonomous systems in developed in less critical, but still challenging applications. A question for the aviation community is how we can best develop practical ease-of-use for aircraft that are sized to carry a small number of passengers (e.g. 1-9) or equivalent cargo. Such development is unlikely to be a single event, but rather a managed, evolutionary process where responsibility and authority transitions from human to automation agents as operational experience is gained with increasingly intelligent systems. This talk presents a technology road map being developed at NASA Langley, as part of an overall strategy to foster ODM, for the development of ease-of-use for ODM aviation.

  12. The effects of retrieval ease on health issue judgments: implications for campaign strategies.

    Chang, Chingching

    2010-12-01

    This paper examines the effects of retrieving information about a health ailment on judgments of the perceived severity of the disease and self-efficacy regarding prevention and treatment. The literature on metacognition suggests that recall tasks render two types of information accessible: the retrieved content, and the subjective experience of retrieving the content. Both types of information can influence judgments. Content-based thinking models hold that the more instances of an event people can retrieve, the higher they will estimate the frequency of the event to be. In contrast, experience-based thinking models suggest that when people experience difficulty in retrieving information regarding an event, they rate the event as less likely to occur. In the first experiment, ease of retrieval was manipulated by asking participants to list either a high or low number of consequences of an ailment. As expected, retrieval difficulty resulted in lower perceived disease severity. In the second experiment, ease of retrieval was manipulated by varying the number of disease prevention or treatment measures participants attempted to list. As predicted, retrieval difficulty resulted in lower self-efficacy regarding prevention and treatment. In experiment three, when information regarding a health issue was made accessible by exposure to public service announcements (PSAs), ease-of-retrieval effects were attenuated. Finally, in experiment four, exposure to PSAs encouraged content-based judgments when the issue was of great concern.

    Background Although insulin therapy is well-accepted by symptomatic diabetic patients, it is still often delayed in less severe patients, in whom injectable insulin remains under-used. A better understanding of patients' perception of insulin would eventually help physicians to adopt the most appropriate dialogue when having to motivate patients to initiate or to intensify insulin injection. Methods The 'Studying the Hurdles of Insulin Prescription' (SHIP) questionnaire was developed based on a list of concepts derived from three diabetic patients' focus groups, and was included into two cross-sectional studies with similar design: SHIP Oral study and SHIP Premix study. Diabetic patients treated with oral hypoglycaemic agents (OHA; n = 1,494) and patients already treated with insulin (n = 1,150) completed the questionnaire at baseline, 6- and 12 months. Psychometric properties were assessed: 1) structure analysis by Principal Component Analysis (PCA) with Varimax rotation, 2) internal consistency reliability (Cronbach's alpha), and 3) concurrent validity (Spearman correlation coefficients with the Fear of Self-Injecting (FSI) score of the Diabetes Fear of Injecting and Self-testing Questionnaire. Reluctance/motivation towards insulin was assessed. Scores' ability to predict patients' insulin injection reluctance/motivation and initiation/intensification was evaluated with the Area Under the Receiver Operating Characteristic (ROC) Curve (AUC). Results PCA analysis confirmed the structure of the 14 items grouped into 3 dimensions: 'acceptance and motivation', 'fear and constraints', and 'restraints and barriers' towards insulin injection. Internal consistency reliability was excellent (Cronbach's alpha > 0.70); concurrent validity was good. The three scores were significantly predictive of patients' reluctance/motivation towards insulin injection initiation, as they were of patients' actual switch, except for the 'restraints and barriers' dimension.

    Freestall dairy farms commonly present issues with cattle slips and falls caused by smooth flooring and manure slurry. This study examined the effect of 4 new methyl methacrylate (MMA) resin aggregate flooring types (1-4) compared with rubber (positive) and concrete (negative control) on dairy cow (n=18) ease of movement when walking on straight and right-angled corridors. Our hypothesis was that cow ease of movement when walking on the MMA surfaces would be better than when walking on traction milled concrete, and at least as good as when walking on rubber. Cattle ease of movement was measured using kinematics, accelerometers, and visual observation of gait and associated behaviors. Stride length, swing time, stance time, and hoof height were obtained from kinematic evaluation. Acceleration and asymmetry of variance were measured with accelerometers. Locomotion score and behaviors associated with lameness, such as arch back, head bob, tracking up, step asymmetry, and reluctance to bear weight were visually observed. Stride length, swing time, stance time, and the number of steps taken were the only variables affected by flooring type. Differences between flooring types for these variables were tested using a generalized linear mixed model with cow as a random effect, week as a random block factor, and flooring type as a fixed effect. Multiple comparisons with a Scheffé adjustment were done to analyze differences among flooring types. Stride length was 0.14 m longer (better) on rubber when compared with concrete, and 0.11 and 0.17 m shorter on MMA 1 and 2 compared with rubber. On MMA 3 and 4, stride length did not differ from either rubber or concrete. Swing time was 0.04 s shorter (worse) on MMA 1 than on rubber, but did not differ from any other flooring. Stance time was 0.18 s longer (worse) on MMA 2 when compared with rubber, but it did not differ from any other treatment. The number of steps was higher on MMA 4 compared with rubber (4.57 vs. 3.95 steps), but

    The use of automated external defibrillators (AED) by lay people has the potential to markedly increase survival from community cardiac arrest. Wider public use of AEDs requires units that can be operated safely and effectively by people with minimal or no training. This study compares the use of three AEDs by untrained lay people regarding ease-of-use, safety, pad positioning and time to defibrillation. 24 subjects with no prior exposure to the use of AEDs were asked to perform simulated defibrillation on a manikin using three defibrillators: Zoll AEDPlus, Medtronic Physio-Control LifePak CR Plus and Philips/Laerdal HeartStart OnSite Defibrillator. Subjects' performance were videotaped and reviewed for time to defibrillate, pad positioning and safety. Subjects were asked to rate the three units in terms of ease-of-use. Average times to first shock were 74.8 s for the Physio-Control, 83.0 s for the Laerdal and 153.4 s for the Zoll defibrillator. Pad positioning was scored as correct in 23/24 Laerdal trials, 19/24 Physio-Control trials and 14/24 Zoll trials. 23 out of the 24 subjects rated the Zoll most difficult to use. All subjects safely stayed clear of the unit when required. The majority of subjects safely and effectively delivered defibrillating shocks without any prior training and within quite acceptable times. Untrained subjects find the Physio-Control and Laerdal Defibrillator easier to use than the Zoll device. Features of AED design that improved ease of use are discussed.

    In this study, the effect of different measurements of ancestral inbreeding on birthweight, calving ease and stillbirth were analysed. Three models were used to estimate the effect of ancestral inbreeding, and the estimated regression coefficient of phenotypic data on different measurements of ancestral inbreeding was used to quantify the effect of ancestral inbreeding. The first model included only one measurement of inbreeding, whereas the second model included the classical inbreeding coefficients and one alternative inbreeding coefficient. The third model included the classical inbreeding coefficients, the interaction between classical inbreeding and ancestral inbreeding, and the classical inbreeding coefficients of the dam. Phenotypic data for this study were collected from February 1998 to December 2008 on three large commercial milk farms. During this time, 36,477 calving events were recorded. All calves were weighed after birth, and 8.08% of the calves died within 48 h after calving. Calving ease was recorded on a scale between 1 and 4 (1 = easy birth, 4 = surgery), and 69.95, 20.91, 8.92 and 0.21% of the calvings were scored with 1, 2, 3 and 4, respectively. The average inbreeding coefficient of inbred animals was 0.03, and average ancestral inbreeding coefficients were 0.08 and 0.01, depending on how ancestral inbreeding was calculated. Approximately 26% of classically non-inbred animals showed ancestral inbreeding. Correlations between different inbreeding coefficients ranged between 0.46 and 0.99. No significant effect of ancestral inbreeding was found for calving ease, because the number of animals with reasonable high level of ancestral inbreeding was too low. Significant effects of ancestral inbreeding were estimated for birthweight and stillbirth. Unfavourable effects of ancestral inbreeding were observed for birthweight. However, favourable purging effects were estimated for stillbirth, indicating that purging could be partly beneficial for genetic

    Data included 393,097 calving ease, 129,520 gestation length, and 412,484 birth weight records on 412,484 Gelbvieh cattle. Additionally, pedigrees were available on 72,123 animals. Included in the models were effects of sex and age of dam, treated as fixed, as well as direct, maternal genetic and permanent environmental effects and effects of contemporary group (herd-year-season), treated as random. In all analyses, birth weight and gestation length were treated as continuous traits. Calving ease (CE) was treated either as a continuous trait in a mixed linear model (LM), or as a categorical trait in linear-threshold models (LTM). Solutions in TM obtained by empirical Bayes (TMEB) and Monte Carlo (TMMC) methodologies were compared with those by LM. Due to the computational cost, only 10,000 samples were obtained for TMMC. For calving ease, correlations between LM and TMEB were 0.86 and 0.78 for direct and maternal genetic effects, respectively. The same correlations but between TMEB and TMMC were 1.00 and 0.98, respectively. The correlations between LM and TMMC were 0.85 and 0.75, respectively. The correlations for the linear traits were above.97 between LM and TMEB but as low as 0.91 between LM and TMMC, suggesting insufficient convergence of TMMC. Computing time required was about 2 hrs, 5 hrs, and 6 days for LM, TMEB and TMMC, respectively, and memory requirements were 169, 171, and 445 megabytes, respectively. Bayesian implementation of threshold model is simple, can be extended to multiple categorical traits, and allows easy calculation of accuracies; however, computing time is prohibitively long for large models.

  19. Due process traditionalism.

    2008-06-01

    In important cases, the Supreme Court has limited the scope of "substantive due process" by reference to tradition, but it has yet to explain why it has done so. Due process traditionalism might be defended in several distinctive ways. The most ambitious defense draws on a set of ideas associated with Edmund Burke and Friedrich Hayek, who suggested that traditions have special credentials by virtue of their acceptance by many minds. But this defense runs into three problems. Those who have participated in a tradition may not have accepted any relevant proposition; they might suffer from a systematic bias; and they might have joined a cascade. An alternative defense sees due process traditionalism as a second-best substitute for two preferable alternatives: a purely procedural approach to the Due Process Clause, and an approach that gives legislatures the benefit of every reasonable doubt. But it is not clear that in these domains, the first-best approaches are especially attractive; and even if they are, the second-best may be an unacceptably crude substitute. The most plausible defense of due process traditionalism operates on rule-consequentialist grounds, with the suggestion that even if traditions are not great, they are often good, and judges do best if they defer to traditions rather than attempting to specify the content of "liberty" on their own. But the rule-consequentialist defense depends on controversial and probably false assumptions about the likely goodness of traditions and the institutional incapacities of judges.

    Blisters differing in design and handling are established as packaging material for solid dosage forms. The ease of opening of blisters influences application and patient's compliance. In this study the influence of visibility and movability of solid dosage forms in blister packaging on both, easy opening and patient's satisfaction, were investigated by target group testing according to ONR CEN/TS 15945. For each testing 20 participants in the age of 65-80 years were recruited randomly. They opened the blisters on realistic terms without any auxiliary devices. Video documentation of the hands' movements was recorded to analyze the opening procedure. To show the influence of visibility of the dosage form in the blister, capsules size 1 were packed in transparent and opaque blisters. A moderate influence of the visibility on both, the ease of opening and patient satisfaction, was observed. A second study dealt with the movability of solid dosage forms in blisters. Therefore, three different sizes of tablets with similar shapes were packed in identical cavities. Limited movability was found as major criterion on effectiveness and effectivity of opening as well as on satisfaction with the opening procedure.

    The Global Polio Eradication Initiative to eradicate polio completely by the year 2000 has been successful, except for three endemic and some non-endemic countries. Pakistan, one of the three endemic polio reservoirs, is posing a serious threat to the success of the initiative. Currently, the expanded programme on immunisation has been geared to win the race over polio virus in Pakistan. After the remarkable decrease in polio cases from 198 in 2011 to only 58 in 2012, Pakistan seemed to be at the verge of success. However, hurdles continue to retard the campaign. The war against terrorism, misconceptions about polio vaccine, religious misinterpretations, frustration among vaccinators, lack of awareness, social considerations, natural calamities, inaccessibility, and inefficient vaccines and so on are continually rupturing the foundations of the worldwide initiative in the country. Weak health management is found at the hub of majority of the challenges. Stricter policies, well managed and supervised plans and strategic actions, risk analysis and enhanced communication may help giving the final punch to polio virus in the country. Analysis suggested that there is some literature available on the challenges to polio elimination, yet there is not a single publication up to date that considers all the possible hurdles in a single manuscript. This paper sorts out the breaches that hamper the goal of eliminating polio from Pakistan. We have evaluated all the possible barriers and explained them with a perspective that will help develop area specific strategies against polio virus and thus eradicate polio virus from the world.

    The growing demand for fresh-like food products has encouraged the development of hurdle technology of non-thermal processing. In this study, freshly squeezed Chokanan mango juice was treated by paired combinations of sonication (for 15 and 30 min at 25 ℃, 40 kHz frequency) and UV-C treatment (for 15 and 30 min at 25 ℃). Selected physicochemical properties, antioxidant activities, microbial inactivation and other quality parameters of combined treated juice were compared to conventional thermal treatment (at 90 ℃ for 60 s). After thermal and combined treatment, no significant changes occurred in physicochemical properties. A significant increase in extractability of carotenoids (15%), polyphenols (37%), flavonoids (35%) and enhancement in antioxidant capacity was observed after combined treatment. Thermal and combined treatment exhibited significant reduction in microbial load. Results obtained support the use of sonication and UV-C in a hurdle technology to improve the quality of Chokanan mango juice along with safety standards.

    Protein engineering and characterisation of non-synonymous single nucleotide variants (SNVs) require accurate prediction of protein stability changes (ΔΔGu) induced by single amino acid substitutions. Here, we have developed a new prediction method called Evolutionary, Amino acid, and Structural Encodings with Multiple Models (EASE-MM), which comprises five specialised support vector machine (SVM) models and makes the final prediction from a consensus of two models selected based on the predicted secondary structure and accessible surface area of the mutated residue. The new method is applicable to single-domain monomeric proteins and can predict ΔΔGu with a protein sequence and mutation as the only inputs. EASE-MM yielded a Pearson correlation coefficient of 0.53-0.59 in 10-fold cross-validation and independent testing and was able to outperform other sequence-based methods. When compared to structure-based energy functions, EASE-MM achieved a comparable or better performance. The application to a large dataset of human germline non-synonymous SNVs showed that the disease-causing variants tend to be associated with larger magnitudes of ΔΔGu predicted with EASE-MM. The EASE-MM web-server is available at http://sparks-lab.org/server/ease.

  8. Local health traditions.

    A very systematic study made in Karjat, Maharasht (a tribal area in India) has found that in comparison with the official health care and primary health centers, the traditional health practices are far more comprehensive. However, although the local traditions are comprehensive in their 'scope', they nevertheless reveal several weaknesses when subjected to critical evaluation by the science of Ayurveda. For example, whereas some remedies are found to be sound, there are others that are incomplete, and some appear to be totally distorted. Similarly, the diagnostic abilities of local practitioners, while sound in some cases, are in several others found to be inadequate. As to the use of local herbs, whereas the local tradition has an amazing knowledge of local flora--the knowledge about properties of plants is in many cases incomplete. There are several reasons that may explain how and why these weaknesses have set in. 1st, the local traditions are 'oral' and in the natural course of things, oral traditions the world over have been found to decay over time. A 2nd, external, reason for the current decay of local traditions is the derision, neglect, and oppression they have suffered due to the intolerance of western scientific tradition. A 3rd reason for weaknesses in the local health stream is the breakdown of active links, during the last few centuries, with the mainstream science of Ayurveda.

    In this study, a 3-trait linear model was used to obtain genetic parameters for direct and maternal components of calving ease (CE), gestation length (GEST), and birth weight (BWT). Calving ease scores were transformed into Snell scores and expressed as percent unassisted calving (SC), ranging from 0 to 100% (least to greatest ease). A total of 40,420 records (n = 14,403 for CE) were obtained from the Canadian Charolais Association field database. The animal model included fixed effects of contemporary group (herd x year of birth combinations), age of heifer, and sex of calf (only for CE), whereas random effects included direct and maternal genetic effects, residual error, and permanent environmental effects (for CE). The BWT and GEST were preadjusted for age of dam and sex of calf effects. Variance components were estimated using REML. Mean SC was 83.31% (SD = 23.30) and ranged from 3.44 to 100%. Mean BWT was 46.54 kg (SD = 4.79), whereas mean GEST was 286.48 d (SD = 4.93). Direct heritability estimates for SC, BWT, and GEST were 0.14 +/- 0.02, 0.46 +/- 0.03, and 0.62 +/- 0.04, respectively, and maternal heritability estimates were 0.06 +/- 0.02, 0.14 +/- 0.02, and 0.10 +/- 0.02, respectively. The permanent environmental effect as a proportion of SC phenotypic variance was 0.35 +/- 0.11, indicating a large influence on CE. Genetic correlations of direct SC with direct BWT and GEST were -0.93 +/- 0.04 and -0.38 +/- 0.08, respectively, whereas maternal correlations were -0.69 +/- 0.14 and -0.49 +/- 0.17, respectively, illustrating the importance of including both traits in CE evaluations. Within trait direct x maternal genetic correlations were substantial and negative. Regression of average direct and average maternal EBV on year of birth yielded significant genetic trends for the direct effects of BWT, GEST, and CE, whereas no trends were detected for maternal effects.

    Background Several sumatriptan subcutaneous autoinjector devices for acute treatment of migraine patients are available, each device differs with respect to design and features. Determining device preference and ease of use is important because patients experiencing a migraine attack are often functionally impaired. Objective The objective of this human factors study was to compare migraine patients’ device use performance and preferences for three sumatriptan subcutaneous autoinjectors: a disposable two-step device (Zembrace® SymTouch®), a disposable three-step device (Sumavel® DosePro®), and a multistep reloadable device (Imitrex® STATdose®), using simulated injections. Methods Each study subject performed two unaided simulated injections with each of three different drug delivery devices, which were presented in counterbalanced order. The participants were then asked to rate the three devices on various subjective measures. The primary end point was overall device preference using a visual analog scale. Results A total of 54 subjects participated and each subject performed two simulated injections with each of the three devices. Most subjects preferred the two-step device (88.9%) to the three-step (13.0%) and the reloadable (1.9%). The two-step device had higher mean overall preference ratings (F (2, 159)=56.6, P<0.01) and higher ratings for ease of use, intuitiveness, convenience, portability, and control. The two-step device had a first injection full-dose delivery success rate of 44.4%, higher than both the reloadable (24.1%) and the three-step (3.7%) devices. The number of errors with the two-step device (n=3) was ~90% lower than the three-step (n=49) and reloadable (n=44) devices. Conclusion In this human factors study, 54 migraineurs used simulated injections to compare three sumatriptan subcutaneous delivery devices. Zembrace SymTouch, a two-step device, was most preferred compared with Sumavel DosePro and Imitrex STATdose. It also ranked highest

  12. Cuff leakage, not paravalvular leakage, in the Carpentier Edwards PERIMOUNT Magna Ease aortic bioprosthesis.

    Though the Carpentier Edwards PERIMOUNT Magna Ease valve is a bioprosthesis with documented excellent haemodynamics and easy implantability, this valve has a gap between the cobalt-chromium-nickel alloy stent and silicone sewing ring. This gap, which is widest just below each of the three commissural struts, lacks silicone and leaves the two-layer polytetrafluoroethylene fabric unsupported and unprotected. If the needle of a valve suture is placed in this structurally weak area of the sewing ring, the resultant fabric tear may result in a true cuff leakage, not the usual paravalvular leakage. We describe this pitfall in the context of a recent operation to alert surgeons everywhere that suture placement too close to the stent (missing the silicone sewing ring) can result in postoperative cuff leakage. We need to be very careful to include the silicone ring in each stitch to prevent injury to the valve cuff of this prosthesis and to avoid cuff leakage.

  13. A cognition-based method to ease the computational load for an extended Kalman filter.

    The extended Kalman filter (EKF) is the nonlinear model of a Kalman filter (KF). It is a useful parameter estimation method when the observation model and/or the state transition model is not a linear function. However, the computational requirements in EKF are a difficulty for the system. With the help of cognition-based designation and the Taylor expansion method, a novel algorithm is proposed to ease the computational load for EKF in azimuth predicting and localizing under a nonlinear observation model. When there are nonlinear functions and inverse calculations for matrices, this method makes use of the major components (according to current performance and the performance requirements) in the Taylor expansion. As a result, the computational load is greatly lowered and the performance is ensured. Simulation results show that the proposed measure will deliver filtering output with a similar precision compared to the regular EKF. At the same time, the computational load is substantially lowered.

  14. Suppressing secrecy through metacognitive ease: cognitive fluency encourages self-disclosure.

    PubMed

    Alter, Adam L; Oppenheimer, Daniel M

    2009-11-01

    Understanding when people reveal unfavorable information about themselves is both practically and theoretically important. Existing research suggests that people tend not to adopt stable disclosure strategies, and consequently disclose too much information in some situations (e.g., embarrassing personal information on Facebook) and too little in other situations (e.g., risky sexual behavior to a physician during diagnosis of a possible sexually transmitted disease). We sought to identify a domain-general cue that predicts self-disclosure patterns. We found that metacognitive ease, or fluency, promoted greater disclosure, both in tightly controlled lab studies (Studies 1a, 1b, and 3) and in an ecologically valid on-line field study (Study 4). Disfluency tended to prime thoughts and emotions associated with risk, which might be one reason why people who experience disfluency are less comfortable with self-disclosure (Studies 2 and 3). We conclude by discussing the implications of these results for theory and clinical practice.

    Insulin pens offer significant benefits over vial and syringe injections for patients with diabetes who require insulin therapy. Insulin pens are more discreet, easier for patients to hold and inject, and provide better dosing accuracy than vial and syringe injections. The Humalog(®) KwikPen™ (prefilled insulin lispro [Humalog] pen, Eli Lilly and Company, Indianapolis, IN, USA) is a prefilled insulin pen highly rated by patients for ease of use in injections, and has been preferred by patients to both a comparable insulin pen and to vial and syringe injections in comparator studies. Together with an engineering study demonstrating smoother injections and reduced dosing error versus a comparator pen, recent evidence demonstrates the Humalog KwikPen device is an accurate, easy-to-use, patient-preferred insulin pen.

  16. Dissociating perception from judgment in the action-specific effect of blocking ease on perceived speed.

    The action-specific approach to perception claims that a person's ability to act directly influences perceptual processes related to spatial vision. For example, a person's ability to block a moving ball impacts perceptual judgments of the ball's speed. However, an alternative explanation is that action rather than perception influences judgments. Here, we explore this distinction directly. Our method produces two distinct effects, one that is clearly a judgment-based effect and is based on the outcome of the trial (trial-outcome effect) and one that is under debate as to whether or not it is perceptual and is based on the ease with which the ball can be blocked (paddle-size effect). We explored whether these two effects would produce convergence or dissociations across various populations and manipulations. A dissociation is evidence for two separate underlying processes, whereas if the two effects did not dissociate, this would be consistent with claims that both effects were judgment-based. In Experiment 1, we examined whether older and younger adults would show a dissociation between the two effects given some precedent for older adults to show greater susceptibility to nonperceptual factors in their judgments. In Experiment 2, we used a cover story to excuse poor performance and examined its effects on both types of effects. Both experiments revealed dissociations, suggesting that while one effect is judgment-based, the other effect is not. Coupled with prior research, we conclude that the action-specific effect of ease to block a ball on estimated ball speed is perceptual.

  17. Towards easing the configuration and new team member accommodation for open source software based portals

    2013-12-01

    For simple portals such as vocabulary based services, which contain small amounts of data and require only hyper-textual representation, it is often an overkill to adopt the whole software stack of database, middleware and front end, or to use a general Web development framework as the starting point of development. Directly combining open source software is a much more favorable approach. However, our experience with the Coastal and Marine Spatial Planning Vocabulary (CMSPV) service portal shows that there are still issues such as system configuration and accommodating a new team member that need to be handled carefully. In this contribution, we share our experience in the context of the CMSPV portal, and focus on the tools and mechanisms we've developed to ease the configuration job and the incorporation process of new project members. We discuss the configuration issues that arise when we don't have complete control over how the software in use is configured and need to follow existing configuration styles that may not be well documented, especially when multiple pieces of such software need to work together as a combined system. As for the CMSPV portal, it is built on two pieces of open source software that are still under rapid development: a Fuseki data server and Epimorphics Linked Data API (ELDA) front end. Both lack mature documentation and tutorials. We developed comparison and labeling tools to ease the problem of system configuration. Another problem that slowed down the project is that project members came and went during the development process, so new members needed to start with a partially configured system and incomplete documentation left by old members. We developed documentation/tutorial maintenance mechanisms based on our comparison and labeling tools to make it easier for the new members to be incorporated into the project. These tools and mechanisms also provided benefit to other projects that reused the software components from the CMSPV

    The aim of this study was to assess whether or not behaviour change techniques (BCTs) as well as engagement and ease-of-use features used in smartphone applications (apps) to aid smoking cessation can be identified reliably. Apps were coded for presence of potentially effective BCTs, and engagement and ease-of-use features. Inter-rater reliability for this coding was assessed. Inter-rater agreement for identifying presence of potentially effective BCTs ranged from 66.8 to 95.1 % with 'prevalence and bias adjusted kappas' (PABAK) ranging from 0.35 to 0.90 (p < 0.001). The intra-class correlation coefficients between the two coders for scores denoting the proportions of (a) a set of engagement features and (b) a set of ease-of-use features, which were included, were 0.77 and 0.75, respectively (p < 0.001). Prevalence estimates for BCTs ranged from <10 % for medication advice to >50 % for rewarding abstinence. The average proportions of specified engagement and ease-of-use features included in the apps were 69 and 83 %, respectively. The study found that it is possible to identify potentially effective BCTs, and engagement and ease-of-use features in smoking cessation apps with fair to high inter-rater reliability.

    Infective endocarditis (IE) has historically caused significant morbidity and mortality. Valve surgery reduces systemic embolization and mortality, but the optimal timing is controversial. The EASE (Early Surgery Versus Conventional Treatment for Infective Endocarditis) trial, which employed strict inclusion and exclusion criteria, showed that early surgery could reduce the risk of embolic events for a subset of patients. The aim of the present study was to determine the proportion of adult IE patients seen in usual clinical practice at a single tertiary medical center that would meet EASE enrollment criteria. Over a four-year period, only 10 of 88 patients (11.3%) were found to meet EASE enrollment criteria. These results have important research implications, and highlight the differences between populations of patients used in clinical trials and patients seen in practice.

    Traditional healers are the first to be called for help when illness strikes the majority of South Africans. Their communities have faith in their ability to cure or alleviate conditions managed by doctors, and much more. A visit to such practitioners' websites (they are up with the latest advertising technology!) shows that they promise help with providing more power, love, security or money, protection from evil people and spirits, enhancing one's sex life with penis enlargement and vagina tightening spells, etc. Contemplating such claims, it is easy to be dismissive of traditional healers. But in this issue of the SAMJ Nompumelelo Mbatha and colleagues1 argue that the traditional healers' regulatory council, promised by an Act of Parliament, should be established, followed by (or preferably preceded by) formal recognition by employers of sick certificates issued by traditional healers. Can matters be so simply resolved? What does this mean for doctors and other formally recognised healthcare professionals, and how to respond to such claims and social pressures?

    1986-04-01

    A radiotracer technique has been used to assess the effects of a 700-ml collapsible holding chamber (InspirEase, Key Pharmaceuticals Inc.) on the deposition of metered-dose aerosols in ten patients with obstructive airways disease (mean forced expiratory volume in one second (FEV1), 64.5 percent of predicted). Patterns of deposition obtained by patients' usual techniques with the metered-dose inhaler (MDI) were compared with those by correct MDI technique (actuation coordinated with slow deep inhalation and followed by ten seconds of breath-holding) and with those by InspirEase. Deposition of aerosol was assessed by placing Teflon particles labelled with 99mTc inside placebo canisters, and inhaling maneuvers were monitored by respiratory inductive plethysmography (Respitrace). Nine of the ten patients had imperfect technique with the MDI, the most prevalent errors being rapid inhalation and failure to hold their breath adequately. With patients' usual MDI techniques, 6.5 +/- 1.2 percent (mean +/- SE) of the dose reached the lungs. This was increased to 11.2 +/- 1.3 percent (p less than 0.02) with correct technique and increased further to 14.8 +/- 1.4 percent (p less than 0.05) with InspirEase. Oropharyngeal deposition exceeded 80 percent of the dose for the MDI alone but was only 9.5 +/- 0.9 percent with InspirEase (p less than 0.01); 59.2 +/- 2.1 percent of the dose was retained within InspirEase itself. It is concluded that InspirEase gives whole lung deposition of metered-dose aerosols greater than that from a correctly used MDI, while oropharyngeal deposition is reduced approximately nine times.

    In Nigeria since 1987, the National Association of Nigeria Nurses and Midwives (NSNNM) has used traditional medial and traditional health care workers to curtail the practice of female circumcision. Other harmful traditions are being changed also, such as early marriage, taboos of pregnancy and childbirth, and scarification. 30,000 member of NANNM are involved in this effort to halt the harmful practices themselves and to change community opinion. The program involved national and state level workshops on harmful health consequences of traditional practices and instruction on how to conduct focus group discussions to assess women's beliefs and practices. The focus groups were found to be a particularly successful method of opening up discussion of taboo topics and expressing deep emotions. The response to the knowledge that circumcision was not necessary was rage and anger, which was channeled into advocacy roles or change in the practice. The result was the channeled into advocacy roles for change in the practice. The result was the development of books, leaflets and videos. One community group designed a dress with a decorative motif of tatoos and bodily cuts to symbolize circumcision and scarring. Plays and songs were written and performed. Artists provided models of female genitalia both before and after circumcision. The campaign has been successful in bringing this issue to the public attention in prominent ways, such a national television, health talk shows, and women;s magazines. One of the most important results of the effort has been the demonstration that culture and tradition can be changed from within, rather than from outside imposition of values and beliefs.

Hemodynamics of the unoccluded and partially occluded filter are examined, and the clinical implications are assessed. The IVC, which is the primary vein that drains the legs, is modeled as a straight pipe, and a geometrically accurate model of the filter is constructed using computer aided design. Blood is modeled as a homogeneous, incompressible, Newtonian fluid, and the method of overset grids is used to solve the Navier-Stokes equations. Results are corroborated with in-vitro studies. Flow around the unoccluded filter demonstrates minimal disruption, but spherical clots in the downstream trapping position lead to regions of stagnant and recirculating flow that may promote further clotting. The volume of stagnant flow and the peak wall shear stress increase with clot volume. For clots trapped in the upstream trapping position, flow is disrupted along the cava wall downstream of the clot and within the filter. The shape and location of trapped clots also effect the peak wall shear stress and may impact the efficacy of the filter.

    As our population continues to age, more nurses will be needed to enter the specialty of LTC nursing to meet the needs of our senior population. To promote this area of nursing and retain new graduate nurses in LTC, more research is required to support the specific challenges faced by LTC nurses compared with those of other areas of nursing. The authors suggest implementation of support strategies that may include a formal preceptorship program of at least one month in duration, additional clinical support on night shifts, coaching and mentoring models, learning opportunities based on a learning needs assessment, and orientation to the overall culture and environment of the home including time spent with all departments. LTC homes need to examine their approaches to leadership, providing comprehensive orientation and resource support for new graduates and developing strategies specific to their organization's mission and vision that will empower and provide support to ease the unique transition to LTC. These strategies lead to promoting positive relationships, professional development and overall positive outcomes with workplace satisfaction in the LTC setting. The authors encourage federal and provincial government officials to examine this more closely and to better support this effort with the financial resources that are greatly needed in LTC homes to provide the exemplary care that our seniors deserve.

  16. A two-year perspective: who may ease the burden of girls’ loneliness in school?

    2014-01-01

    Background Loneliness is negatively related to good health and wellbeing, especially among girls. There is little research, however, on factors that may ease the burdens of loneliness in the school setting. Thus, we explored the relationship between girls’ loneliness and later school wellbeing adjusted for other adversities. Furthermore, we assessed the significance of having someone whom the girl trusted by investigating possible modifying influences on the addressed association. Methods Altogether, 119 girls in grades 1–8 provided baseline data and answered the same set of questions two years later. Logistic regression models including perceived academic problems, victimisation by bullying, loneliness and trusted others were tested with bad versus good school wellbeing two years later as outcome using SPSS. Results In the multivariable analysis of loneliness, academic problems, and victimisation, loneliness was the only variable showing a strong and negative contribution to later school wellbeing. Next, demonstrated in separate models; the inclusion of having a trusted class advisor fully attenuated the association of loneliness with later school wellbeing. In contrast, other trusted teachers, trusted parents, or trusted students did not affect the association. Conclusions Loneliness in girls strongly predicted school wellbeing two years later. However, having a class advisor whom the girl trusted to contact in hurtful situations clearly reduced the burden of loneliness. This finding highlights the clinical importance of stability, long-lasting relations, and trust that main teachers may represent for lonely girls. PMID:24712912

    Many chronic obstructive pulmonary disease (COPD) patients use their inhaler ineffectively and there is a trend towards increased inhaler resistance. We wanted to answer two questions: Is there a difference in preference and ease of use between Diskus (DK) and Handihaler (HH)? How acceptable are inhalation resistances? Sixty COPD patients, naive to DK and HH, but experienced in the use of other inhalers, had to read the instruction leaflet and demonstrate their inhalation technique. If errors were made, instruction was given and inhalation technique was checked again. Patients had to state a preference for DK or HH. Subsequently they inhaled through a range of resistances and scored the acceptability. There was no difference in the number of instructions needed for both inhalers. One third inhaled perfectly after reading the instruction leaflet, which increased to 85% after one instruction. More patients preferred the DK (43) than the HH (16). With decreasing resistance acceptability increases, but it reaches a plateau. Patients have a clear preference for the DK. There is no difference in the number of instructions needed to obtain a perfect inhalation technique, but for some patients one instruction is not enough. The trend to increase the resistance of inhalers has reached a critical point with regard to acceptability.

    Working memory is important for online language processing during conversation. We use it to maintain relevant information, to inhibit or ignore irrelevant information, and to attend to conversation selectively. Working memory helps us to keep track of and actively participate in conversation, including taking turns and following the gist. This paper examines the Ease of Language Understanding model (i.e., the ELU model, Rönnberg, 2003; Rönnberg et al., 2008) in light of new behavioral and neural findings concerning the role of working memory capacity (WMC) in uni-modal and bimodal language processing. The new ELU model is a meaning prediction system that depends on phonological and semantic interactions in rapid implicit and slower explicit processing mechanisms that both depend on WMC albeit in different ways. It is based on findings that address the relationship between WMC and (a) early attention processes in listening to speech, (b) signal processing in hearing aids and its effects on short-term memory, (c) inhibition of speech maskers and its effect on episodic long-term memory, (d) the effects of hearing impairment on episodic and semantic long-term memory, and finally, (e) listening effort. New predictions and clinical implications are outlined. Comparisons with other WMC and speech perception models are made. PMID:23874273

    The present study investigated the effect of keypad layout on the ease of operating small cell phones with the thumb in one-handed operations by young and elderly male and female participants. Eighteen young participants (9 males and 9 females) and 12 elderly participants (6 males and 6 females) operated 9 different keypads modeled after commercially available cordless handsets. Keypads designed by using the L9 orthogonal array differed in vertical pitch (V-Pitch: 7, 8, 9 mm) between keys, horizontal pitch (H-Pitch: 10, 11, 12 mm) between keys, the margin below the bottom row of keys (B-Margin: 5, 13, 21 mm), and phone body width (P-Width: 38, 41, 44 mm). Results concerning subjective overall usability showed the lowest scores for a V-Pitch of 7 mm and a B-Margin of 5 mm in most groups. However, for the female participants, with shorter thumbs, the increase in V-pitch did not improve operability. In the elderly participants, miskeying frequently occurred at dial keys of specific numbers. These findings suggest that the preferable keypad layout differs between different age groups and between male and female participants.

    We investigate experimentally the effective Coulomb friction exerted by a granular medium on a shearing plate, varying the medium depth. The plate is driven by a spring connected to a motor turning at a constant speed and, depending on the system configuration, performs continuous sliding or stick and slip in different proportions. We introduce an order parameter which discriminates between the different regimes expressing the fraction of time spent in slipping. At low driving speed, starting from zero layers of interstitial granular material, the average friction coefficient decreases when a few layers are added, while the order parameter stays close to zero. By further increasing the granular depth, the friction undergoes a sudden increase but the order parameter does not change notably. At an intermediate driving speed, however, both the friction and the order parameter undergo a sudden increase, which for the order parameter amounts to several orders of magnitude, indicating that the plate is more braked but nevertheless keeps sliding more easily. For medium-high driving speeds, full sliding is obtained for only one layer of interstitial matter, where friction has a minimum, and is maintained for all increasing depths while friction increases. These observations show that the ease of slipping is not determined by friction alone, rather by the highly complex interplay between driving velocity, friction, and the depth of the medium.

    BACKGROUND: Modifications defined to ease bending of the support bar and lateral stabilizer placement during minimal invasive repair of pectus excavatum (MIRPE) have not been reported. We herein report our experience with MIRPE including several technical modifications. METHODS: A total of 87 patients who underwent MIRPE were evaluated retrospectively. Technical modifications are (1) a template drawn preoperatively according to the anthropometric measurements, (2) more laterally placed thoracal incisions, (3) single existing incision for multiple support bars, (4) to secure lateral stabilizers to support bar in inverted position. RESULTS: The mean patient age was 11.2 ± 3.8 years. The mean operating time was 63.7 ± 18.7 min. The mean Haller index was 5.4 ± 2.1. Eight patients necessitated two support bars. The support bars were removed in 69 patients after the completion of treatment. Support bars were left in place 26.8 ± 4.3 months. Final chest contours of the 56 patients were evaluated as 12 months passed after support bar removal and excellent repair results were determined in 84.2%. CONCLUSION: Preoperative bending of the support bar according to anthropometric measurements and fixation of the lateral stabilizers to the support bar in inverted position facilitates bar shaping and lateral stabilizer placement.

  2. Special report: the truth about condoms. Barriers to better condom "killing people"; regulatory, political hurdles stifle development.

    PubMed

    1995-01-01

    The condom industry in the US is dominated by Carter Wallace and the London International Group. They offer very little product differentiation. Ten years ago, however, two engineers in a small California laboratory began working on a nonlatex condom which would be both stronger and more sensitive than the traditional male latex condom. Their efforts resulted in the development of the polyurethane Avanti condom currently being marketed in thirteen states of the Western US. Made by London International Group plc in Cambridge, England, Avanti should be available nationwide as of April 1995. The public, however, has received only very little information about the product and the US Food and Drug Administration (FDA) is concerned about the safety and efficacy of polyurethane/plastic condoms. Six other condom manufacturers are developing plastic condoms, with at least five such condoms awaiting FDA premarket clearance to be marketed. Recent delays in marketing Avanti are due to disagreements between the manufacturer and the FDA over labeling. Other delays have involved safety and efficacy concerns. Bob Kohmescher, public health analyst with the US Centers for Disease Control office of the assistant director of HIV/AIDS, notes that even his agency is moving slower than expected on the polyurethane condom and has not reached a consensus over how to describe them. In the effort to protect themselves, FDA officials have insisted upon labeling which recommends plastic condoms for use by only people who are allergic to latex. These labeling guidelines, finalized in November, are so restrictive that some manufacturers cannot take their products to market. Despite these current FDA obstacles to bringing a higher quality condom to the US market, industry experts and health officials hope that the polyurethane and other plastic condoms will expand the practice of safer sex, while providing an alternative method of barrier protection for the estimated 1-2 million American adults

    The Aboriginal people in Canada have been noted to have low self-esteem, subsequently increasing their risk of HIV. To this effect, two traditional healing practices are being used to help these people avoid HIV infection, and to live more healthily and positively if they are infected. The first method is the Medicine Wheel, which is a traditional model used to represent the complex interrelationship among all living things and show how their immune system is physically affected by their emotions and worries. Many Aboriginal AIDS Organizations, counselors and others are now using this AIDS teaching Wheel model. Meanwhile, the second method is the Sharing Circles, which provide an environment where people feel safe to talk about HIV and give participants a sense of support and a means for expression without stigma or judgement. As a result, many people who attend HIV circles begin to take better care of themselves and of others. Overall, it is emphasized that these traditional healing practices can be effectively adapted for use in HIV counseling and education.

    "Mini-tablets" (MTs) are tablets of diameter≤3mm and have been widely studied and developed. However, reports comparing MTs with other tablet formulations are few. We wished to evaluate the ease of taking a MT quantitatively in comparison with an orally disintegrating mini-tablet (ODMT), conventional tablet (CT) and conventional orally disintegrating tablet (ODT). Four types of tablets were prepared. We prepared tablets of two diameters (3mm for MTs and ODMTs vs. 8mm for CTs and ODTs) and two formulations (MTs and CTs vs. ODMTs and ODTs). Our randomized crossover trial in 18 healthy volunteers (8 men and 10 women; mean age, 22.5years) indicated that the visual analog scale (VAS) score for the ease and amount of water required for intake of MTs was significantly lower than those of CTs. An ODMT required the least amount of water and smallest VAS score for the ease of taking a tablet. Our results showed that the advantage of MTs with regard to the ease of taking and decreased amount of water required was exerted for a unit of dosing comprising <5 tablets. These data suggested the usefulness of MTs and the importance of the number of MTs for comfortable consumption by patients.

    The Cambridge Tropospheric Trajectory model of Chemistry and Transport (CiTTyCAT), a Lagrangian chemistry model, has been evaluated using atmospheric chemical measurements collected during the East Atlantic Summer Experiment 1996 (EASE '96). This field campaign was part of the UK Natural Environment Research Council's (NERC) Atmospheric Chemistry Studies in the Oceanic Environment (ACSOE) programme, conducted at Mace Head, Republic of Ireland, during July and August 1996. The model includes a description of gas-phase tropospheric chemistry, and simple parameterisations for surface deposition, mixing from the free troposphere and emissions. The model generally compares well with the measurements and is used to study the production and loss of O 3 under a variety of conditions. The mean difference between the hourly O 3 concentrations calculated by the model and those measured is 0.6 ppbv with a standard deviation of 8.7 ppbv. Three specific air-flow regimes were identified during the campaign - westerly, anticyclonic (easterly) and south westerly. The westerly flow is typical of background conditions for Mace Head. However, on some occasions there was evidence of long-range transport of pollutants from North America. In periods of anticyclonic flow, air parcels had collected emissions of NO x and VOCs immediately before arriving at Mace Head, leading to O 3 production. The level of calculated O 3 depends critically on the precise details of the trajectory, and hence on the emissions into the air parcel. In several periods of south westerly flow, low concentrations of O 3 were measured which were consistent with deposition and photochemical destruction inside the tropical marine boundary layer.

    Background and objective Doc'CISMeF (DC) is a semantic search engine used to find resources in CISMeF-BP, a quality controlled health gateway, which gathers guidelines available on the internet in French. Visualization of Concepts in Medicine (VCM) is an iconic language that may ease information retrieval tasks. This study aimed to describe the creation and evaluation of an interface integrating VCM in DC in order to make this search engine much easier to use. Methods Focus groups were organized to suggest ways to enhance information retrieval tasks using VCM in DC. A VCM interface was created and improved using the ergonomic evaluation approach. 20 physicians were recruited to compare the VCM interface with the non-VCM one. Each evaluator answered two different clinical scenarios in each interface. The ability and time taken to select a relevant resource were recorded and compared. A usability analysis was performed using the System Usability Scale (SUS). Results The VCM interface contains a filter based on icons, and icons describing each resource according to focus group recommendations. Some ergonomic issues were resolved before evaluation. Use of VCM significantly increased the success of information retrieval tasks (OR=11; 95% CI 1.4 to 507). Nonetheless, it took significantly more time to find a relevant resource with VCM interface (101 vs 65 s; p=0.02). SUS revealed ‘good’ usability with an average score of 74/100. Conclusions VCM was successfully implemented in DC as an option. It increased the success rate of information retrieval tasks, despite requiring slightly more time, and was well accepted by end-users. PMID:24650636

    To distinguish between ewe and lamb breed effects on prenatal growth, ease of parturition and early lamb behaviour, an embryo-transfer study was carried out using a hill breed (Scottish Blackface; liveweight: 54.25 +/- 1.03 kg, mean +/- s.e.m.) and a lowland breed (Suffolk; 80.33 +/- 1.52 kg) to obtain the four possible combinations of ewe and lamb. Data were collected from 38 Blackface ewes (18 with Blackface lambs and 20 with Suffolk lambs) and 41 Suffolk ewes (20 with Blackface lambs and 21 with Suffolk lambs); all ewes were given single embryos. Suffolk lambs had a significantly longer gestation than Blackface lambs (1.5 days, P < 0.01), regardless of ewe breed. Suffolk lambs also had a longer labour (20 min, P < 0.05) and were significantly more likely to require birth assistance (17/21, 81% of all assisted deliveries; P < 0.001), as were male lambs (19/21, 90%; P < 0.01). These variables were independent of ewe breed. Blackface lambs were significantly more active than Suffolk lambs in the first 2 h after birth; ewe breed had little effect on lamb behaviour. Blackface lambs stood twice as quickly as Suffolk lambs after birth (13 min v. 24 min; P < 0.001), and were significantly more likely to suckle within the first 2 h after birth (92% v. 66%; P < 0.05). The behavioural retardation of Suffolk lambs may be a consequence of their birth difficulty which increases their likelihood of suffering birth trauma and hypoxia at parturition. Together, these factors may increase the probability of neonatal death in these lambs.

    Drug delivery across the skin is used for several millennia to ease gastrointestinal (GI) ailments in Traditional Persian Medicine (TPM). TPM topical remedies are generally being applied on the stomach, lower abdomen, lower back and liver to alleviate GI illnesses such as dyspepsia, gastritis, GI ulcers, inflammatory bowel disease, intestinal worms and infections. The aim of the present study is to survey the topical GI remedies and plant species used as ingredients for these remedies in TPM. In addition, pharmacological activities of the mentioned plants have been discussed. For this, we searched major TPM textbooks to find plants used to cure GI problems in topical use. Additionally, scientific databases were searched to obtain pharmacological data supporting the use of TPM plants in GI diseases. Rosa × damascena, Pistacia lentiscus, Malus domestica, Olea europaea and Artemisia absinthium are among the most frequently mentioned ingredients of TPM remedies. β-asarone, amygdalin, boswellic acids, guggulsterone, crocin, crocetin, isomasticadienolic acid, and cyclotides are the most important phytochemicals present in TPM plants with GI-protective activities. Pharmacological studies demonstrated GI activities for TPM plants supporting their extensive traditional use. These plants play pivotal role in alleviating GI disorders through exhibiting numerous activities including antispasmodic, anti-ulcer, anti-secretory, anti-colitis, anti-diarrheal, antibacterial and anthelmintic properties. Several mechanisms underlie these activities including the alleviation of oxidative stress, exhibiting cytoprotective activity, down-regulation of the inflammatory cytokines, suppression of the cellular signaling pathways of inflammatory responses, improving re-epithelialization and angiogenesis, down-regulation of anti-angiogenic factors, blocking activity of acetylcholine, etc. PMID:28392893

    Imitation and language processing are closely connected. According to the Ease of Language Understanding (ELU) model (Rönnberg et al., 2013) pre-existing mental representation of lexical items facilitates language understanding. Thus, imitation of manual gestures is likely to be enhanced by experience of sign language. We tested this by eliciting imitation of manual gestures from deaf and hard-of-hearing (DHH) signing and hearing non-signing children at a similar level of language and cognitive development. We predicted that the DHH signing children would be better at imitating gestures lexicalized in their own sign language (Swedish Sign Language, SSL) than unfamiliar British Sign Language (BSL) signs, and that both groups would be better at imitating lexical signs (SSL and BSL) than non-signs. We also predicted that the hearing non-signing children would perform worse than DHH signing children with all types of gestures the first time (T1) we elicited imitation, but that the performance gap between groups would be reduced when imitation was elicited a second time (T2). Finally, we predicted that imitation performance on both occasions would be associated with linguistic skills, especially in the manual modality. A split-plot repeated measures ANOVA demonstrated that DHH signers imitated manual gestures with greater precision than non-signing children when imitation was elicited the second but not the first time. Manual gestures were easier to imitate for both groups when they were lexicalized than when they were not; but there was no difference in performance between familiar and unfamiliar gestures. For both groups, language skills at T1 predicted imitation at T2. Specifically, for DHH children, word reading skills, comprehension and phonological awareness of sign language predicted imitation at T2. For the hearing participants, language comprehension predicted imitation at T2, even after the effects of working memory capacity and motor skills were taken into

    The antimicrobial activity of organic acids in combination with nonchemical treatments was evaluated for inactivation of Salmonella enterica serotype Typhimurium within 1 min. It was observed that the effectiveness of the multiple-hurdle treatments was temperature (P ≤ 0.05) and pH (P ≤ 0.05) dependent and corresponded to the degree of organic acid lipophilicity (sodium acetate being least effective and sodium propionate being the most effective). This led to the hypothesis that the loss in viability was due at least in part to cell membrane disruption. Evaluation of osmotic response, potassium ion leakage, and transmission electron micrographs confirmed treatment effects on the cell membrane. Interestingly, all treatments, even those with no effect on viability, such as with sodium acetate, resulted in measurable cellular stress. Microarray experiments explored the specific response of S. Typhimurium to sodium acetate and sodium propionate, the most similar of the tested treatments in terms of pKa and ionic strength, and found little difference in the changes in gene expression following exposure to either, despite their very different effects on viability. Taken together, the results reported support our hypothesis that treatment with heated, acidified, organic acid salt solutions for 1 min causes loss of S. Typhimurium viability at least in part by membrane damage and that the degree of effectiveness can be correlated with lipophilicity of the organic acid. Overall, the data presented here indicate that a combined thermal, acidified sodium propionate treatment can provide an effective antimicrobial treatment against Salmonella. PMID:21478311

    According to an article by Wald in the November 2000 issue of Strategic Healthcare Marketing, through physician education, integrated medicine shall continue to be adopted by conventional medical establishments in the United States. With many leading medical schools now adding courses on alternative medicine and hospital administrators recognizing this growing trend, responding to the patients' needs and demands remains paramount. According to a study of 3200 physicians conducted by Health Products Research, physicians expect to offer and embrace therapeutic alternatives outside of the traditional pharmaceutical realm. Greater than 50% will begin or increase using alternative medicine in the next 12 months. Physicians also believe that patient acceptance is greater for alternative therapies, resulting in therapeutic compliance. Most physicians continue to be skeptical about certain treatments, citing a lack of clinical information. With these factors understood, more clinical research to be completed in a teaching hospital environment becomes paramount.

    The energy expenditure of the Shuttle Flight 61-B crewmembers during the extravehicular performance of Experimental Assembly of Structures in EVA (EASE) and Assembly Concept of Construction of Space Structures (ACCESS) construction system tasks are reported. These data consist of metabolic rate time profiles correlated with specific EASE and ACCESS tasks and crew comments. Average extravehicular activity metabolic rates are computed and compared with those reported from previous Apollo, Shylab, and Shuttle flights. These data reflect total energy expenditure and not that of individual muscle groups such as hand and forearm. When correlated with specific EVA tasks and subtasks, the metabolic profile data is expected to be useful in planning future EVA protocols. For example, after experiencing high work rates and apparent overheating during some Gemini EVAs, it was found useful to carefully monitor work rates in subsequent flights to assess the adequacy of cooling garments and as an aid to preplanning EVA procedures. This presentation is represented by graphs and charts.

    Calving ease scores from Holstein dairy cattle in the Walloon Region of Belgium were analysed using univariate linear and threshold animal models. Variance components and derived genetic parameters were estimated from a data set including 33,155 calving records. Included in the models were season, herd and sex of calf × age of dam classes × group of calvings interaction as fixed effects, herd × year of calving, maternal permanent environment and animal direct and maternal additive genetic as random effects. Models were fitted with the genetic correlation between direct and maternal additive genetic effects either estimated or constrained to zero. Direct heritability for calving ease was approximately 8% with linear models and approximately 12% with threshold models. Maternal heritabilities were approximately 2 and 4%, respectively. Genetic correlation between direct and maternal additive effects was found to be not significantly different from zero. Models were compared in terms of goodness of fit and predictive ability. Criteria of comparison such as mean squared error, correlation between observed and predicted calving ease scores as well as between estimated breeding values were estimated from 85,118 calving records. The results provided few differences between linear and threshold models even though correlations between estimated breeding values from subsets of data for sires with progeny from linear model were 17 and 23% greater for direct and maternal genetic effects, respectively, than from threshold model. For the purpose of genetic evaluation for calving ease in Walloon Holstein dairy cattle, the linear animal model without covariance between direct and maternal additive effects was found to be the best choice.

    We investigated the possible effects of auditory verbal cues on flavor perception and swallow physiology for younger and elder participants. Apple juice, aojiru (grass) juice, and water were ingested with or without auditory verbal cues. Flavor perception and ease of swallowing were measured using a visual analog scale and swallow physiology by surface electromyography and cervical auscultation. The auditory verbal cues had significant positive effects on flavor and ease of swallowing as well as on swallow physiology. The taste score and the ease of swallowing score significantly increased when the participant's anticipation was primed by accurate auditory verbal cues. There was no significant effect of auditory verbal cues on distaste score. Regardless of age, the maximum suprahyoid muscle activity significantly decreased when a beverage was ingested without auditory verbal cues. The interval between the onset of swallowing sounds and the peak timing point of the infrahyoid muscle activity significantly shortened when the anticipation induced by the cue was contradicted in the elderly participant group. These results suggest that auditory verbal cues can improve the perceived flavor of beverages and swallow physiology.

  5. Using endophenotypes to examine molecules related to candidate genes as novel therapeutics: The "endophenotype-associated surrogate endpoint (EASE)" concept.

    PubMed

    Yamasue, Hidenori

    2015-10-01

    In this article, a new concept of an "endophenotype-associated surrogate endpoint (EASE)" is proposed. To examine effect of a novel therapeutic molecule on a target phenotype of a genotype associated with the molecule, state-dependent aspect of an endophenotype can be used as a surrogate endpoint. Desired characteristics for EASE are (1) a close relationship to the endophenotype associated with therapeutics, (2) longitudinal changes in illness severity, while the original "endophenotype" is primarily state independent, (3) a physical sign or laboratory measurement that occurs in association with a pathological process and has putative diagnostic and/or prognostic utility, and (4) serves as a substitute for a clinically meaningful endpoint. Advantages are expected for both surrogate endpoints in drug development and endophenotypes in uncovering pathogenesis. EASE are closer to molecules than clinically meaningful endpoints and can respond to administration of the molecule in a more direct manner. Therefore, a statistically significant effect is likely to be observed in clinical trials with smaller sample sizes and shorter durations. As with endophenotypes, reduced heterogeneity might be expected especially in heterogeneous syndromes such as psychiatric disorders. Potential interactions (e.g., elucidating biological mechanisms underlying novel treatments) can be further expected.

    Over the course of the past two to three decades, intraoral digital impression systems have gained acceptance due to high accuracy and ease of use as they have been incorporated into the fabrication of dental implant restorations. The use of intraoral digital impressions enables the clinician to produce accurate restorations without the unpleasant aspects of traditional impression materials and techniques. This article discusses the various types of digital impression systems and their accuracy compared to traditional impression techniques. The cost, time, and patient satisfaction components of both techniques will also be reviewed.

    To the software design community, the concern over the costs associated with a program's execution time and implementation is great. It is always desirable, and sometimes imperative, that the proper programming technique is chosen which minimizes all costs for a given application or type of application. This paper describes a study that compared the cost-related factors associated with traditional programming techniques to rale-based programming techniques for a specific application. The results of this study favored the traditional approach regarding execution efficiency, but favored the rule-based approach regarding programmer productivity (implementation ease). Although this study examined a specific application, the resuli:s should be widely applicable.

    Mental health professionals have the experience and skills necessary to provide care and support to colleagues and peers in these troubled and stressful times. Yet, traditionally nurses have not been supportive of one another. Not receiving much interest from the feminist movement and not willingly to embrace feminist social activism, the nursing profession has suffered as it continues to embrace racist, classist, sexist, and homophobic outdated theories and research practices. Without a collective voice which unites all nurses in a common struggle, issues related to mental health nursing will continue to be viewed in a fragmented way. Until feminist research, theory, and practice become central to the profession's ideology, nurses will continue to be divided among themselves, unable to provide the necessary caring for one another.

    Background With advances in mobile technology, accessibility of clinical resources at the point of care has increased. Objective The objective of this research was to identify if six selected mobile point-of-care tools meet the needs of clinicians in internal medicine. Point-of-care tools were evaluated for breadth of coverage, ease of use, and quality. Methods Six point-of-care tools were evaluated utilizing four different devices (two smartphones and two tablets). Breadth of coverage was measured using select International Classification of Diseases, Ninth Revision, codes if information on summary, etiology, pathophysiology, clinical manifestations, diagnosis, treatment, and prognosis was provided. Quality measures included treatment and diagnostic inline references and individual and application time stamping. Ease of use covered search within topic, table of contents, scrolling, affordance, connectivity, and personal accounts. Analysis of variance based on the rank of score was used. Results Breadth of coverage was similar among Medscape (mean 6.88), Uptodate (mean 6.51), DynaMedPlus (mean 6.46), and EvidencePlus (mean 6.41) (P>.05) with DynaMed (mean 5.53) and Epocrates (mean 6.12) scoring significantly lower (P<.05). Ease of use had DynaMedPlus with the highest score, and EvidencePlus was lowest (6.0 vs 4.0, respectively, P<.05). For quality, reviewers rated the same score (4.00) for all tools except for Medscape, which was rated lower (P<.05). Conclusions For breadth of coverage, most point-of-care tools were similar with the exception of DynaMed. For ease of use, only UpToDate and DynaMedPlus allow for search within a topic. All point-of-care tools have remote access with the exception of UpToDate and Essential Evidence Plus. All tools except Medscape covered criteria for quality evaluation. Overall, there was no significant difference between the point-of-care tools with regard to coverage on common topics used by internal medicine clinicians. Selection of

    On 20 March, the Monsanto Company received a long-awaited approval from the European Community's (EC) Committee for Veterinary Medicinal Products (CVMP) for its version of recombinant bovine somatotropin (BST), a growth hormone that, when injected into cows, can increase milk production up to 20%. Under normal circumstances, the generally positive recommendation would have meant BST was headed for market. But BST is no ordinary drug. Controversies have raged on both sides of the Atlantic, not only about its safety but whether it is needed at all during a time of surplus milk production - and whether its use would drive many small farmers out of business when cheap, hormone-induced milk from agribusiness floods the market. That concern led the EC's Council of Agricultural Ministers in April 1990 to declare a moratorium on the marketing of BST. The ban, recently extended to the end of this year, is designed to allow completion of several studies - including a look at the effect BST would have on European agriculture.

  13. Microbial inactivation and shelf life comparison of 'cold' hurdle processing with pulsed electric fields and microfiltration, and conventional thermal pasteurisation in skim milk.

    Thermal pasteurisation (TP) is the established food technology for commercial processing of milk. However, degradation of valuable nutrients in milk and its sensory characteristics occurs during TP due to substantial heat exposure. Pulsed electric fields (PEF) and microfiltration (MF) both represent emerging food processing technologies allowing gentle milk preservation at lower temperatures and shorter treatment times for similar, or better, microbial inactivation and shelf stability when applied in a hurdle approach compared to TP. Incubated raw milk was used as an inoculum for the enrichment of skim milk with native microorganisms before PEF, MF, and TP processing. Inoculated milk was PEF-processed at electric field strengths between 16 and 42 kV/cm for treatment times from 612 to 2105 μs; accounting for energy densities between 407 and 815 kJ/L, while MF was applied with a transmembrane flux of 660 L/h m². Milk was TP-treated at 75°C for 24 s. Comparing PEF, MF, and TP for the reduction of the native microbial load in milk led to a 4.6 log₁₀ CFU/mL reduction in count for TP, which was similar to 3.7 log₁₀ CFU/mL obtained by MF (P≥0.05), and more effective than the 2.5 log₁₀ CFU/mL inactivation achieved by PEF inactivation (at 815 kJ/L (P<0.05)). Combined processing with MF followed by PEF (MF/PEF) produced a 4.1 (at 407 and 632 kJ/L), 4.4 (at 668 kJ/L) and 4.8 (at 815 kJ/L) log₁₀ CFU/mL reduction in count of the milk microorganisms, which was comparable to that of TP (P≥0.05). Reversed processing (PEF/MF) achieved comparable reductions of 4.9, 5.3 and 5.7 log₁₀ CFU/mL (at 407, 632 and 668 kJ/L, respectively (P≥0.05)) and a higher inactivation of 7.1 log₁₀ (at 815 kJ/mL (P<0.05)) in milk than for TP. Microbial shelf life of PEF/MF-treated (815 kJ/L) and TP-treated milk stored at 4°C was analysed over 35 days for total aerobic; enterobacteria; yeasts and moulds; lactobacilli; psychrotroph; thermoduric psychrotroph, mesophilic

    The challenges in successful vaccination against influenza using conventional approaches lie in their variable efficacy in different age populations, the antigenic variability of the circulating virus, and the production and manufacturing limitations to ensure safe, timely, and adequate supply of vaccine. The conventional influenza vaccine platform is based on stimulating immunity against the major neutralizing antibody target, hemagglutinin (HA), by virus attenuation or inactivation. Improvements to this conventional system have focused primarily on improving production and immunogenicity. Cell culture, reverse genetics, and baculovirus expression technology allow for safe and scalable production, while adjuvants, dose variation, and alternate routes of delivery aim to improve vaccine immunogenicity. Fundamentally different approaches that are currently under development hope to signal new generations of influenza vaccines. Such approaches target nonvariable regions of antigenic proteins, with the idea of stimulating cross-protective antibodies and thus creating a "universal" influenza vaccine. While such approaches have obvious benefits, there are many hurdles yet to clear. Here, we discuss the process and challenges of the current influenza vaccine platform as well as new approaches that are being investigated based on the same antigenic target and newer technologies based on different antigenic targets.

    Purpose Computerized cognitive behavioral therapy (CCBT) has been shown to be efficacious. Moreover, CCBT can be enhanced by using physiological and activity sensors, but there is no evidence about the acceptability of all these tools. The objective of this study is to examine the efficacy, expectations, satisfaction, and ease of use of an Internet-based CCBT program for preventing depression, with and without sensors (electroencephalography, electrocardiograhpy ECG, and actigraphy), in a high-risk population (unemployed men). Patients and methods Sixty participants at risk of depression (unemployed men) were randomly assigned to three experimental conditions: 1) intervention program (N=22), 2) intervention program plus sensors (N=19), and 3) control group (N=19). Participants completed depression, anxiety, positive and negative affect, and perceived stress measures. Furthermore, they also completed the measures for expectation, satisfaction, and the ease of use of the program. Results Results showed that the two intervention groups improved significantly more than the control group on the clinical variables, and the improvements were greater in the group that used sensors than in the group that did not use them. Furthermore, participants in both intervention groups scored high on expectations and satisfaction with the CCBT program (with and without sensors). The mean score for usability was 88 out of 100 (standard deviation =12.32). No significant differences were found between groups on any of these variables. Conclusion This is the first study to analyze the efficacy, expectations, satisfaction, and ease of use of an Internet-based program using physiological and activity sensors. These results suggest that an Internet program for depression with or without physiological and activity sensors is effective, satisfactory, and easy to use. PMID:27042067

    Mobile technology use is nearly ubiquitous which affords the opportunity for using these technologies for modifying health related behaviors. At the same time, use of mobile health (mHealth) technology raises privacy and security concerns of consumers. The goal of this analysis was to understand the perceived ease of use, usefulness, risk and trust that contribute to behavioral intention to use a mobile application for meeting the healthcare needs of persons living with HIV (PLWH). To understand these issues, we conducted focus group sessions with 50 persons living with HIV and 30 HIV healthcare providers. We used the e-commerce acceptance model to analyze our focus group data. Findings from the study demonstrated the need for mHealth to be perceived as useful, easy to use, with little perceived risk accompanied by a measure of trust in the creators of the technology. Findings from this work can inform future work on patients and providers' perceptions of risk, trust, ease of use and usefulness of mHealth technology.

    The model alga Chlamydomonas reinhardtii has been used to pioneer genetic engineering techniques for high-value protein and biofuel production from algae. To date, most studies of transgenic Chlamydomonas have utilized the chloroplast genome due to its ease of engineering, with a sizeable suite of reporters and well-characterized expression constructs. The advanced manipulation of algal nuclear genomes has been hampered by limited strong expression cassettes, and a lack of high-throughput reporters. We have improved upon an endogenous reporter gene - the ARS2 gene encoding an arylsulfatase enzyme - that was first cloned and characterized decades ago but has not been used extensively. The new construct, derived from ARS2 cDNA, expresses significantly higher levels of reporter protein and transforms more efficiently, allowing qualitative and quantitative screening using a rapid, inexpensive 96-well assay. The improved arylsulfatase expression cassette was used to screen a new transgene promoter from the ARG7 gene, and found that the ARG7 promoter can express the ARS2 reporter as strongly as the HSP70-RBCS2 chimeric promoter that currently ranks as the best available promoter, thus adding to the list of useful nuclear promoters. This enhanced arylsulfatase reporter construct improves the efficiency and ease of genetic engineering within the Chlamydomonas nuclear genome, with potential application to other algal strains.

    NASA Astrophysics Data System (ADS)

    Ward, Robert E.; Carpenter, Charles E.

    This chapter describes traditional methods for analysis of minerals involving titrimetric and colorimetric procedures, and the use of ion selective electrodes. Other traditional methods of mineral analysis include gravimetric titration (i.e., insoluble forms of minerals are precipitated, rinse, dried, and weighed) and redox reactions (i.e., mineral is part of an oxidation-reduction reaction, and product is quantitated). However, these latter two methods will not be covered because they currently are used little in the food industry. The traditional methods that will be described have maintained widespread usage in the food industry despite the development of more modern instrumentation such as atomic absorption spectroscopy and inductively coupled plasma-atomic emission spectroscopy (Chap. 24). Traditional methods generally require chemicals and equipment that are routinely available in an analytical laboratory and are within the experience of most laboratory technicians. Additionally, traditional methods often form the basis for rapid analysis kits (e.g., Quantab®; for salt determination) that are increasingly in demand. Procedures for analysis of minerals of major nutritional or food processing concern are used for illustrative purposes. For additional examples of traditional methods refer to references (1-6). Slight modifications of these traditional methods are often needed for specific foodstuffs to minimize interferences or to be in the range of analytical performance. For analytical requirements for specific foods see the Official Methods of Analysis of AOAC International (5) and related official methods (6).

    Transient celestial phenomena feature prominently in the astronomical knowledge and traditions of Aboriginal Australians. In this paper, I collect accounts of the Aurora Australis from the literature regarding Aboriginal culture. Using previous studies of meteors, eclipses, and comets in Aboriginal traditions, I anticipate that the physical properties of aurora, such as their generally red colour as seen from southern Australia, will be associated with fire, death, blood, and evil spirits. The survey reveals this to be the case and also explores historical auroral events in Aboriginal cultures, aurorae in rock art, and briefly compares Aboriginal auroral traditions with other global indigenous groups, including the Maori of New Zealand.

  4. Ease of counterfactual thought generation moderates the relationship between need for cognition and punitive responses to crime.

    PubMed

    Petrocelli, John V; Dowd, Keith

    2009-09-01

    Punitive responses to crime have been linked to a relatively low need for cognition (NFC). Sargent's (2004) findings suggest that this relationship is due to a relatively complex attributional system, employed by high-NFC individuals, which permits them to recognize potential external or situational causes of crime. However, high-NFC individuals may also be more likely to engage in counterfactual thinking, which has been linked to greater judgments of blame and responsibility. Three studies examine the relationship between trait and state NFC and punitiveness in light of counterfactual thinking. Results suggest that the ease of generating upward counterfactuals in response to an unfortunate crime moderates the NFC-punitiveness relationship, such that high-NFC individuals are less punitive than low-NFC individuals only when counterfactual thoughts are relatively difficult to generate. These findings are discussed in light of punishment theory and their possible implications with regard to the legal system.

    2013-06-01

    This article develops the constitutive features of the society-of-captives thesis as suggested by Arrigo and Milovanovic, and Arrigo, Bersot, and Sellers. The relevance of this thesis is briefly explored in relation to the institutional and community-based treatment philosophies that currently inform the mental health and criminal justice systems. This exploration specifies how risk (being human and doing humanness differently) is managed symbolically, linguistically, materially, and culturally. The management of this risk extends to the kept as well as to their keepers, regulators, and watchers (i.e., the society of captives). This article calls for a new clinical praxis (being/doing a critical mindfulness) designed to overcome the totalizing madness (the harm of social dis-ease) that follows from managing risk fearfully and marginalizing identities desperately as reified recursively through society's captivity. The ethical underpinnings of this clinical praxis represent an emergent direction for undertaking correctional policy reform.

    Socioeconomic disparities influence the usage rate of advanced communication technologies in Canada. It is important to assess all patient interactions with computers and electronic devices based on these socioeconomic differences. This project studied the ease of use of a touch-screen interface program for collecting patient feedback. The interface collected feedback on physicians' communication skills, an important health concern that has been garnering more and more attention. A concurrent paper survey was used to gather information on the socioeconomic status and the usability of the touchscreen device. As expected, patients who were older, had lower annual household income, and had lower educational attainment were associated with more difficulty using the devices. Surprisingly, 94% of all users (representing a wide range of socioeconomic status backgrounds) rated the device as easy to use.

    The Affordable Care Act has extended coverage for uninsured and underinsured Americans, but it could exacerbate existing problems of access to primary care. Shared medical appointments (SMAs) are one way to improve access and increase practice productivity, but few studies have examined the patient's perspective on participation in SMAs. To understand patient experiences, 5 focus group sessions were conducted with a total of 30 people in the San Francisco Bay Area. The sessions revealed that most participants felt that they received numerous tangible and intangible benefits from SMAs, particularly enhanced engagement with other patients and physicians, learning, and motivation for health behavior change. Most importantly, participants noted changes in the power dynamic during SMA visits as they increasingly saw themselves empowered to impart information to the physician. Although SMAs improve access, engagement with physicians and other patients, and knowledge of patients' health, they also help to ease the workload for physicians.

    Objective Pen needles used for subcutaneous injections have gradually become shorter, thinner and more thin walled, and thereby less robust to patient reuse. Thus, different needle sizes, alternative tip designs and needles resembling reuse were tested to explore how needle design influences ease of insertion, pain and skin trauma. Research design and methods 30 subjects with injection-treated type 2 diabetes and body mass index 25–35 kg/m2 were included in the single-blinded study. Each subject received abdominal insertions with 18 different types of needles. All needles were tested twice per subject and in random order. Penetration force (PF) through the skin, pain perception on 100 mm visual analog scale, and change in skin blood perfusion (SBP) were quantified after the insertions. Results Needle diameter was positively related to PF and SBP (p<0.05) and with a positive pain trend relation. Lack of needle lubrication and small ‘needle hooks’ increased PF and SBP (p<0.05) but did not affect pain. Short-tip, obtuse needle grinds affected PF and SBP, but pain was only significantly affected in extreme cases. PF in skin and in polyurethane rubber were linearly related, and pain outcome was dependent of SBP increase. Conclusions The shape and design of a needle and the needle tip affect ease of insertion, pain and skin trauma. Relations are seen across different data acquisition methods and across species, enabling needle performance testing outside of clinical trials. Trial registration number NCT02531776; results.

    The goal of this study was to examine the perceived usefulness and the perceived ease of use of a Hospital Information System (HIS) for the care staff. We administrated a questionnaire composed of open-end and closed questions. As results, the perceived usefulness and ease of use are correlated with medical occupations. Content analysis of open questions highlights three factors influencing these constructs: ergonomics, errors in the documenting process and insufficient compatibility with the medical department or the occupation. While the results are consistent with literature, they show medical occupations do not report the same low rate of perceived usefulness and of ease of use. The main explanation consists in the medical risk in the prescription process for anesthesiologists, surgeons and physicians.

    To prevent transmission in Ebola Virus Disease (EVD) outbreaks, it is recommended to disinfect living things (hands and people) with 0.05% chlorine solution and non-living things (surfaces, personal protective equipment, dead bodies) with 0.5% chlorine solution. In the current West African EVD outbreak, these solutions (manufactured from calcium hypochlorite (HTH), sodium dichloroisocyanurate (NaDCC), and sodium hypochlorite (NaOCl)) have been widely used in both Ebola Treatment Unit and community settings. To ensure solution quality, testing is necessary, however test method appropriateness for these Ebola-relevant concentrations has not previously been evaluated. We identified fourteen commercially-available methods to test Ebola-relevant chlorine solution concentrations, including two titration methods, four DPD dilution methods, and six test strips. We assessed these methods by: 1) determining accuracy and precision by measuring in quintuplicate five different 0.05% and 0.5% chlorine solutions manufactured from NaDCC, HTH, and NaOCl; 2) conducting volunteer testing to assess ease-of-use; and, 3) determining costs. Accuracy was greatest in titration methods (reference-12.4% error compared to reference method), then DPD dilution methods (2.4-19% error), then test strips (5.2-48% error); precision followed this same trend. Two methods had an accuracy of <10% error across all five chlorine solutions with good precision: Hach digital titration for 0.05% and 0.5% solutions (recommended for contexts with trained personnel and financial resources), and Serim test strips for 0.05% solutions (recommended for contexts where rapid, inexpensive, and low-training burden testing is needed). Measurement error from test methods not including pH adjustment varied significantly across the five chlorine solutions, which had pH values 5-11. Volunteers found test strip easiest and titration hardest; costs per 100 tests were $14-37 for test strips and $33-609 for titration. Given the

  11. Evaluation function of drinking ease from aluminum beverage bottles relative to optimum bottle opening diameter and beverage type.

    In recent years, aluminum beverage bottles having screw tops with opening diameters of 28 and 38 mm have been launched in the Japanese market in keeping with the modern-day drinking habits of consumers. Although Japanese consumers are familiar with such bottles, a majority of them feel that the 28 mm opening is too small and the 38 mm opening is too large. Therefore, we felt the need to develop a method for evaluating consumer feelings when they drink a beverage directly from the bottle opening. For this purpose, we propose an evaluation function of drinking ease that calculates the optimum opening diameter of the bottle. From results of our previous study, we know that there exists an ideal volume of beverage flowing into the mouth, at which consumers feel most comfortable while drinking directly from bottles. Therefore, we define the evaluation function of drinking ease in terms of the difference between the actual volume of fluid in the mouth and the expected ideal volume. If this difference is small, consumers probably feel comfortable while drinking the beverage. We consider a design variable, i.e., the opening diameter, and two state variables, i.e., the volume of beverage remaining in the bottle and the height of consumers, and construct the response surface of the evaluation function by using radial basis function networks. In addition, for investigating the influence of beverage type on the evaluation function, we select green tea and a carbonated beverage (Coke) as test beverages. Results of optimization of the proposed function show that when the opening diameters are 35.4 mm and 34.4 mm in the case of green tea and Coke, respectively, the actual volume of fluid in the mouth is closest to the ideal volume and the participants feel most comfortable. These results are in agreement with results of our previous study that an opening diameter of 33 mm is optimum for young Japanese adults. Thus, we confirm that the proposed function is accurate; it can be used

    The incidence of cancer overall in Mediterranean countries is lower than in Scandinavian countries, the United Kingdom, and the United States. This is mostly accounted for by the lower incidence among Mediterranean countries of cancer of the large bowel, breast, endometrium, and prostate. These forms of cancer have been linked to dietary factors, particularly low consumption of vegetables and fruit, and to a certain extent, high consumption of meat. The traditional Mediterranean diet is characterized by high consumption of foods of plant origin, relatively low consumption of red meat, and high consumption of olive oil, which in several studies has been reported to be more beneficial against cancer than other forms of added lipids. By taking into account the established or presumed nutritional causation of major forms of cancer and the composition of the traditional Mediterranean diet, estimates can be derived concerning the fraction of cancer occurrence in highly developed Western countries that could be attributed to their diets in comparison with the healthy traditional Mediterranean diet. Although estimates can only be crude, it can be calculated that up to 25% of the incidence of colorectal cancer, approximately 15% of the incidence of breast cancer, and approximately 10% of the incidence of prostate, pancreas, and endometrial cancer could be prevented if the populations of highly developed Western countries could shift to the traditional healthy Mediterranean diet.

    PubMed

    Zitek, Emily M; Tiedens, Larissa Z

    2012-01-01

    We tested the hypothesis that social hierarchies are fluent social stimuli; that is, they are processed more easily and therefore liked better than less hierarchical stimuli. In Study 1, pairs of people in a hierarchy based on facial dominance were identified faster than pairs of people equal in their facial dominance. In Study 2, a diagram representing hierarchy was memorized more quickly than a diagram representing equality or a comparison diagram. This faster processing led the hierarchy diagram to be liked more than the equality diagram. In Study 3, participants were best able to learn a set of relationships that represented hierarchy (asymmetry of power)--compared to relationships in which there was asymmetry of friendliness, or compared to relationships in which there was symmetry--and this processing ease led them to like the hierarchy the most. In Study 4, participants found it easier to make decisions about a company that was more hierarchical and thus thought the hierarchical organization had more positive qualities. In Study 5, familiarity as a basis for the fluency of hierarchy was demonstrated by showing greater fluency for male than female hierarchies. This study also showed that when social relationships are difficult to learn, people's preference for hierarchy increases. Taken together, these results suggest one reason people might like hierarchies--hierarchies are easy to process. This fluency for social hierarchies might contribute to the construction and maintenance of hierarchies.

    Recent resuscitation guidelines for cardiopulmonary resuscitation emphasize that rescuers should perform tracheal intubation with minimal interruption of chest compressions. We evaluated the use of video guidance to facilitate tracheal intubation with the Airtraq (ATQ) laryngoscope during chest compression. Eighteen novice physicians in our anesthesia department performed tracheal intubation on a manikin using the ATQ with a video camera system (ATQ-V) or with no video guidance (ATQ-N) during chest compression. All participants were able to intubate the manikin using the ATQ-N without chest compression, but five failed during chest compression (P < 0.05). In contrast, all participants successfully secured the airway with the ATQ-V, with or without chest compression. Concurrent chest compression increased the time required for intubation with the ATQ-N (without chest compression 14.8 ± 4.5 s; with chest compression, 28.2 ± 10.6 s; P < 0.05), but not with the ATQ-V (without chest compression, 15.9 ± 5.8 s; with chest compression, 17.3 ± 5.3 s; P > 0.05). The ATQ video camera system improves the ease of tracheal intubation during chest compressions.

    The UK health service, which had been diagnosed to be seriously out of step with good design practice, has been recommended to obtain knowledge of design and risk management practice from other safety-critical industries. While these other industries have benefited from a broad range of systems modelling approaches, healthcare remains a long way behind. In order to investigate the healthcare-specific applicability of systems modelling approaches, this study identified 10 distinct methods through meta-model analysis. Healthcare workers' perception on 'ease of use' and 'usefulness' was then evaluated. The characterisation of the systems modelling methods showed that each method had particular capabilities to describe specific aspects of a complex system. However, the healthcare workers found that some of the methods, although potentially very useful, would be difficult to understand, particularly without prior experience. This study provides valuable insights into a better use of the systems modelling methods in healthcare. STATEMENT OF RELEVANCE: The findings in this study provide insights into how to make a better use of various systems modelling approaches to the design and risk management of healthcare delivery systems, which have been a growing research interest among ergonomists and human factor professionals.

    Implantable cardioverter-defibrillators (ICDs) terminate ventricular tachycardia (VT) and ventricular fibrillation (VF) with high efficacy and can protect patients from sudden cardiac death (SCD). However, inappropriate shocks may occur if tachycardias are misdiagnosed. Inappropriate shocks are harmful and impair patient quality of life. The risk of inappropriate therapy increases with lower detection rates programmed in the ICD. Single-chamber detection poses greater risks for misdiagnosis when compared with dual-chamber devices that have the benefit of additional atrial information. However, using a dual-chamber device merely for the sake of detection is generally not accepted, since the risks associated with the second electrode may outweigh the benefits of detection. Therefore, BIOTRONIK developed a ventricular lead called the Linox(SMART) S DX, which allows for the detection of atrial signals from two electrodes positioned at the atrial part of the ventricular electrode. This device contains two ring electrodes; one that contacts the atrial wall at the junction of the superior vena cava (SVC) and one positioned at the free floating part of the electrode in the atrium. The excellent signal quality can only be achieved by a special filter setting in the ICD (Lumax 540 and 740 VR-T DX, BIOTRONIK). Here, the ease of implantation of the system will be demonstrated.

    Panax ginseng Meyer has been widely used as a tonic in traditional Korean, Chinese, and Japanese herbal medicines and in Western herbal preparations for thousands of years. In the past, ginseng was very rare and was considered to have mysterious powers. Today, the efficacy of drugs must be tested through well-designed clinical trials or meta-analyses, and ginseng is no exception. In the present review, we discuss the functions of ginseng described in historical documents and describe how these functions are taken into account in herbal prescriptions. We also discuss the findings of experimental pharmacological research on the functions of ginseng in ginseng-containing prescriptions and how these prescriptions have been applied in modern therapeutic interventions. The present review on the functions of ginseng in traditional prescriptions helps to demystify ginseng and, as a result, may contribute to expanding the use of ginseng or ginseng-containing prescriptions.

    2011-02-01

    The bovine placental growth factor-encoding gene (PGF) was analysed as a positional and functional candidate gene for the maternal effect on stillbirth and calving ease in first parity. Prominent levels of PGF expression have been reported for the whole human placenta and umbilical vein endothelial cells. Modulation of angiogenesis, vessel remodelling and vascular permeability during implantation and placentation suggest an influence on trophoblast function during pregnancy. Changes of expression or protein function may therefore be crucial to pregnancy and parturition. By comparative sequencing of bulls with extreme approximate daughter yield deviations for calving traits, we identified 37 SNPs and two insertions/deletions within the PGF gene. Seventeen of the identified polymorphisms were genotyped in 368 selected bulls and tested for association with approximate daughter yield deviations for calving traits. In a single marker analysis, all SNPs were significantly associated with maternal stillbirth and calving ease first parity. The allele substitutions of the significant SNPs explain 8% to 14% and 8% to 15% of the additive genetic variance for maternal stillbirth and maternal calving ease first parity, respectively. There is no evidence that any of the polymorphisms identified within this study could be the causal mutation underlying the QTL, which is likely to be a regulatory mutation. In summary, we report polymorphisms in the bovine PGF gene significantly associated with the maternal effect on stillbirth and calving ease in animals under selection. These results should be confirmed and extended in further studies to identify the causal mutation underlying the QTL analysed.

    Two endotracheal tubes (ETTs) are available for use in operative suites for intubation: the Parker Flex-Tip (PFT, Parker Medical) and the standard Mallinckrodt (Covidien). To the authors' knowledge, no study has compared these 2 ETTs with each other when the anesthesia provider uses the GlideScope video laryngoscope (Verathon) for intubation. The purpose of the study was to determine if there are differences related to ease of intubation reported by anesthesia providers who use the PFT tube compared with the standard tube while using the GlideScope. The study was a randomized block intervention design. The sample consisted of 58 observed intubations in an operating room setting. Data analysis was completed with a 2-factor analysis of covariance using 2 covariates. The PFT tube in suboptimal conditions demonstrated a significantly greater ease of intubation, as measured by decreased time for ETT insertion and greater ease of ETT insertion score. The number of redirections at the glottis to intubate the trachea once the glottis was visualized was not statistically different. Based on the findings from this study, anesthesia providers may want to consider the use of the PFT tube when using the GlideScope to promote ease of intubation.

    The usage amount of medicinal plant rapidly increased along with the development of traditional Chinese medicine industry. The higher market demand and the shortage of wild herbal resources enforce us to carry out large-scale introduction and cultivation. Herbal cultivation can ease current contradiction between medicinal resources supply and demand while they bring new problems such as pesticide residues and plant disease and pests. Researchers have recently placed high hopes on the application of natural fostering, a new method incorporated herbal production and diversity protecting practically, which can solve the problems brought by artificial cultivation. However no modes can solve all problems existing in current herbal production. This study evaluated different production modes including cultivation, natural fostering, and wild collection to guide the traditional Chinese medicine production for sustainable utilization of herbal resources.

    In this study, we compared two endotracheal tubes (cuffed [Murphy Eye type] and uncuffed [Cole type]) and a pediatric laryngeal mask airway (LMA) with respect to their ease of use in rabbits and their capacities to limit waste isoflurane emissions. Animals (New Zealand White, 3.3 to 5.0 kg, n = 8) were sedated with intramuscular ketamine (50 mg/kg) and xylazine (10 mg/kg). After 5 min, the larynx was numbed with cetocaine, an intubation device was positioned, and anesthesia was maintained with isoflurane (2%) in oxygen (1 liter/min). Real-time atmospheric isoflurane emissions were assessed at the rabbit's oral commissure and in the operator's breathing zone (45 cm from the rabbit's nose) by using a portable infrared spectrophotometer. The LMA was placed more easily than was either endotracheal tube, especially by novices. The cuffed tube was positioned more readily than was the uncuffed variant. All three devices emitted isoflurane. The concentrations measured at the oral commissure for the LMA (mean +/- standard error, 8.4 +/- 0.6 ppm) were modestly higher than those acquired for the cuffed (6.7 +/- 0.5 ppm) and uncuffed (6.3 +/- 0.4 ppm) endotracheal tubes; the difference between the LMA and uncuffed tube was significant (P = 0.012). Isoflurane was not detected in the operator's breathing zone. These data show that the uncuffed endotracheal tube (usually used to anesthetize birds and reptiles) and the pediatric LMA can be used in rabbits as readily as a cuffed tube. In addition, our findings indicate that tradeoffs will be required in selecting a delivery system for this species, as the easiest apparatus (the LMA) also emits the most isoflurane waste.

    Objectives: The present study evaluates the therapeutic efficacy of cell suspension of Spirulina platensis (SP) on estrous cycle, fetal development and embryopathy in alloxan (AXN) induced hyperglycemic mice. Materials and Methods: Diabetes was induced by intra-peritoneal administration of AXN. Mice with blood glucose level above 200 mg/dl were divided into Group I (control), Group II (diabetic control), Group III (diabetic control mice fed with SP), and Group IV (control mice fed with SP). Litter counts, estrous cycles, percent survival of litter, and gestation length were recorded. Results: In hyperglycemic mice, a significant (P < 0.05) increase in duration of diestrus (14.48%), estrus (84.21%), and metestrus (164.15%) with concomitant decrease in proestrus phase by 26.13% was recorded when compared with control. Reduction in litter count and survival of litter was 68.67% and 88.38%, respectively, whereas gestation length increased to 14.51% day in diabetic mice, but recovery in these parameters was observed (P < 0.05) when subjected to SP treatment. SP resulted in increased fertility rate from 77.5% to 82.5% and dropped off resorption of the fetus to 33.73% while the survival rate of offspring of diabetic mice went up to 88.89% from 83.61%. Conclusions: These findings suggest that SP is effective in improving the reproductive performance and easing teratogenic effects in diabetic mice and hence warrants further detailed dose-dependent studies to understand its mechanism of action.

    Over the last decade, opioid-related deaths in the United States have increased at an alarming rate. The use of naloxone by laypersons is a newer concept and its utilization can benefit patients by rapid administration due to it being readily available immediately after an opioid overdose. The US Food and Drug Administration approved a naloxone auto-injector on April 3, 2014 for adults and pediatrics, designed for use by anyone including patients, family members, bystanders, and medical professionals. This device (EZVIO™) is the first device of its kind available on the market. The auto-injector is a battery-operated disposable 0.4 mg/0.4 mL prefilled device for use in the lateral thigh by patients, bystanders, or health care professionals. It utilizes auditory and visual commands for ease of administration and instructs patients to seek further medical care after injection. EVZIO costs about $600 for two auto-injectors and a trainer. Additionally, in August 2013, the Substance Abuse and Mental Health Services Administration introduced the Opioid Overdose Toolkit, a federal resource promoting safety and prevention information. This extensive document provides information for medical professionals, first responders, patients, caregivers, and overdose survivors. It outlines many strategies for dealing with this health care crisis. Most importantly, it highlights the importance of rapid recognition and treatment of opioid overdoses as well as routine conversations with patients assessing the need for naloxone prescriptions. The auto-injector is a safe, portable device with limited instruction needed and should routinely be made available to anyone who has contact with an opioid user.

    The Ease of Caregiving for Children is a parent-completed measure of how difficult it is for them to safely help their children participate in activities of daily living. The objectives of this study were to determine the internal consistency, test–retest reliability, and construct validity (known groups methods) of the Ease of Caregiving for Children and create an interval-level scale. Participants included 429 parents of children with cerebral palsy (CP) and 110 parents of children without motor delay. Children ranged in age from 18 to 60 months. Parents completed the Ease of Caregiving for Children and therapists assessed children's gross motor function. The Rasch model of item response analysis was used to create an interval-level scale. Results indicated high internal consistency and acceptable test-retest reliability. Ease of caregiving varied by children's ages for parents of children without motor delay, however there was no significant difference by age for parents of children with CP. Parents of children with less gross motor ability reported more difficulty in caregiving than parents of children with higher gross motor ability. Rasch analysis for children with CP resulted in a hierarchical ordering of items by difficulty with good fit and logical ordering. Findings support the Ease of Caregiving for Children as a reliable and valid measure of parents' perceptions of their difficulty to safely assist their children to perform activities of daily living. The measure should enable health care providers to assess and provide interventions that address families' needs in caring for their children with CP.

    Traditional Chinese medicine (TCM) is an ancient holistic medicine based on the doctrine of Tao and Qi. Tao represents an alteration from which the polarity of Yin and Yang arises and Qi is the vitality which circulates through the body. Therapeutic concepts of TCM include acupuncture, herbal therapy, nutrition and Tuina, a form of manual therapy. TCM is now gaining increased acceptance in the Western society as a complementary therapy. Acupuncture and herbal therapy are the main forms of implementation of TCM in urology.

    This presentation addresses a different aspect of the human-computer interface; specifically the human-information interface. This interface will be dominated by an emerging technology called Information Visualization (IV). IV goes beyond the traditional views of computer graphics, CADS, and enables new approaches for engineering. IV specifically must visualize text, documents, sound, images, and video in such a way that the human can rapidly interact with and understand the content structure of information entities. IV is the interactive visual interface between humans and their information resources.

    The use of traditional cosmetics and remedies such as kohl and henna is very common in Morocco, especially among women, children and babies. Kohl is a dangerous eye cosmetic. It is usually mixed with other harmful substances, then applied on women's eyebrows and used in skin treatments for infants. Henna is another traditional product, with religious associations, which has been widely used over the centuries for cosmetic and medical purposes. Many people add various herbs or other substances to the henna in order to strengthen it or to give it a stronger colour. Our results were reassuring in that the concentrations of lead found in non-elaborate (henna only) samples of henna were low. However, when henna was mixed with other products (elaborate henna), these concentrations increased. Lead concentrations in kohl were very high however, unlike henna, were lower in mixed kohl as mixing with other products diluted the concentration of lead. Nevertheless, in both types of kohl, lead concentrations were very high and consequently constitute a risk for public health, particularly for children.

  7. Elephant resource-use traditions.

    2016-03-01

    African elephants (Loxodonta africana) use unusual and restricted habitats such as swampy clearings, montane outcrops and dry rivers for a variety of social and ecological reasons. Within these habitats, elephants focus on very specific areas for resource exploitation, resulting in deep caves, large forest clearings and sand pits as well as long-established and highly demarcated routes for moving between resources. We review evidence for specific habitat exploitation in elephants and suggest that this represents socially learned cultural behaviour. Although elephants show high fidelity to precise locations over the very long term, these location preferences are explained neither by resource quality nor by accessibility. Acquiring techniques for exploiting specific resource sites requires observing conspecifics and practice and is evidence for social learning. Elephants possess sophisticated cognitive capacities used to track relationships and resources over their long lifespans, and they have an extended period of juvenile dependency as a result of the need to acquire this considerable social and ecological knowledge. Thus, elephant fidelity to particular sites results in traditional behaviour over generations, with the potential to weaken relationships between resource quality and site preferences. Illustrating the evidence for such powerful traditions in a species such as elephants contributes to understanding animal cognition in natural contexts.

    This study explores diet differences between two populations of wild Bornean orangutans (Pongo pygmaeus wurmbii) to assess whether a signal of social learning can be detected in the observed patterns. The populations live in close proximity and in similar habitats but are separated by a river barrier that is impassable to orangutans in the study region. We found a 60% between-site difference in diet at the level of plant food items (plant species-organ combinations). We also found that individuals at the same site were more likely to eat the same food items than expected by chance. These results suggest the presence of diet (food selection) traditions. Detailed tests of three predictions of three models of diet acquisition allowed us to reject a model based on exclusive social learning but could not clearly distinguish between the remaining two models: one positing individual exploration and learning of food item selection and the other one positing preferential social learning followed by individual fine tuning. We know that maturing orangutans acquire their initial diet through social learning and then supplement it by years of low-level, individual sampling. We, therefore, conclude that the preferential social learning model produces the best fit to the geographic patterns observed in this study. However, the very same taxa that socially acquire their diets as infants and show evidence for innovation-based traditions in the wild paradoxically may have diets that are not easily distinguished from those acquired exclusively through individual learning.

  9. Traditional gamma cameras are preferred.

    2016-08-01

    Although the new solid-state dedicated cardiac cameras provide excellent spatial and energy resolution and allow for markedly reduced SPECT acquisition times and/or injected radiopharmaceutical activity, they have some distinct disadvantages compared to traditional sodium iodide SPECT cameras. They are expensive. Attenuation correction is not available. Cardio-focused collimation, advantageous to increase depth-dependent resolution and myocardial count density, accentuates diaphragmatic attenuation and scatter from subdiaphragmatic structures. Although supplemental prone imaging is therefore routinely advised, many patients cannot tolerate it. Moreover, very large patients cannot be accommodated in the solid-state camera gantries. Since data are acquired simultaneously with an arc of solid-state detectors around the chest, no temporally dependent "rotating" projection images are obtained. Therefore, patient motion can be neither detected nor corrected. In contrast, traditional sodium iodide SPECT cameras provide rotating projection images to allow technologists and physicians to detect and correct patient motion and to accurately detect the position of soft tissue attenuators and to anticipate associated artifacts. Very large patients are easily accommodated. Low-dose x-ray attenuation correction is widely available. Also, relatively inexpensive low-count density software is provided by many vendors, allowing shorter SPECT acquisition times and reduced injected activity approaching that achievable with solid-state cameras.

    A review of the literature dating back to 1966, supplemented by interviews with members of the Vietnamese community in Edmonton, Alberta, was conducted to examine and understand how differences in the cultural backgrounds of Canadian physicians and their Vietnamese patients can affect the quality and efficacy of prenatal and postnatal treatment. The available data suggest that traditional Vietnamese beliefs and practices regarding birth are very different from the biomedical view held by the Canadian medical system. The experiences and beliefs of the Vietnamese respondents support this finding. Such cultural differences could contribute to misunderstandings between physicians and patients, and affect the quality and efficacy of health care provided. A sensitive and open approach to the patient's belief system, and open and frank communication are needed to ensure effective prenatal and postnatal treatment for recent Vietnamese immigrants and refugees.

  11. Teaching methods: Tradition and innovation

    1990-06-01

    It has always been difficult to distinguish between tradition and innovation in teaching methods, not least because of the absence of clear-cut criteria. Definitions of teaching methods are also loose rather than binding. Nevertheless a trend towards active participation by studients is noticeable and very often taken as marking `progressive' teaching. Starting from the basic relationship of method and objective, an attempt is made to further relate cognitive activity of students to specific levels of achievement which are considered as teaching objectives. It is suggested, too, that a loose notion of method can for practical purposes be replaced by a more reliable notion of teaching text whether presented orally or given in written form. Then the problem of innovation in teaching methods can be stated a bit more precisely as that of creating a good teaching text. Some suggestions of how this can be achieved are discussed.

    Louisiana State University runs a field camp with a permanent fixed-base which has continually operated since 1928 in the Front Range just to the south of Colorado Springs, CO. The field camp program which offers a 6-credit hour course in Field Geology follows a very traditional structure. The first week is spent collecting data for the construction of a detailed stratigraphic column of the local geology. The second week is spent learning the skills of geologic mapping, while the third applies these skills to a more geologically complicated mapping area. The final three weeks of the field camp program are spent studying and mapping igneous and metamorphic rocks as well as conducting a regional stratigraphic correlation exercise. Historically there has been a lack of technology involved in this program. All mapping has been done in the field without the use of any digital equipment and all products have been made in the office without the use of computers. In the summer of 2011 the use of GPS units, and GIS software were introduced to the program. The exercise that was chosen for this incorporation of technology was one in which metamorphic rocks are mapped within Golden Gate Canyon State Park in Colorado. This same mapping exercise was carried out during the 2010 field camp session with no GPS or GIS use. The students in both groups had the similar geologic backgrounds, similar grade point averages, and similar overall performances at field camp. However, the group that used digital mapping techniques mapped the field area more quickly and reportedly with greater ease. Additionally, the students who used GPS and GIS included more detailed rock descriptions with their final maps indicating that they spent less time in the field focusing on mapping contacts between units. The outcome was a better overall product. The use of GPS units also indirectly caused the students to produce better field maps. In addition to greater ease in mapping, the use of GIS software to

    Participation in ancient traditions is facilitating the current spread of HIV through India. For most of the year, Koovagam is a typical Indian village. Each April on the night of the full moon, however, the Chittirai-Pournami festival is held in Koovagam, a celebration in homage to Aravan during which up to 2000 pilgrims from across the country engage in thousands of acts of unprotected sexual intercourse. Aravan is a man depicted in a Hindu tale who asked to experience sexual bliss before being sacrificed to the gods. To fulfill this last wish, the god Krishna is said to have assumed the form of a beautiful woman and had sexual intercourse with Aravan. Many of the festival participants are hijras, eunuchs and transsexuals who sell sex for a living. Hijras may be accompanied by men who serve as their sex partners and bodyguards. Surveys suggest that one-third of the 10,000 hijras in New Delhi may be infected with HIV. Other participants are known as dangas, men who are either married or single and appear to lead strictly heterosexual lives throughout the year except during the Chittirai-Pournami festival when they dress as women and sell sex to other men attending the festival. The panthis comprise another group of participants and tend to be either single or married men who attend the festival to have sex with the hijras and dangas for fees up to ten rupees, approximately US$0.50, per sexual encounter. Prostitution within the devadasi sect and the sale of young, virgin girls in the state of Andhra Pradesh to the highest male bidders are other examples of how ancient traditions are facilitating the current spread of HIV in India.

    Ease of entry and exit is important for creating a positive first impression of a car and increasing customer satisfaction. Several methods are used within vehicle development to optimise ease of entry and exit, including CAD reviews, benchmarking and buck trials. However, there is an industry trend towards digital methods to reduce the costs and time associated with developing physical prototypes. This paper reports on a study of entry strategy in three properties (buck, car, CAVE) in which inconsistencies were demonstrated by people entering a vehicle representation in the CAVE. In a second study industry practitioners rated the CAVE as worse than physical methods for identifying entry and exit issues, and having lower perceived validity and reliability. However, the resource issues associated with building bucks were recognised. Recommendations are made for developing the CAVE and for combinations of methods for use at different stages of a vehicle's development.

    Background: Expansion of clinical trials activity into emerging regions has raised concerns regarding participant rights and research ethics. Increasing numbers of observational studies are now conducted in developing economies, including the United Arab Emirates. Materials and Methods: This study compares the content of information provided, Good Clinical Practice (GCP) guideline compliance, and readability of informed consent forms (ICFs) for observational compared to interventional studies. Results: GCP compliance for observational studies averaged at 79.5% + 6.8%, significantly (P < 0.001) lower than 92.2 + 5.0 percent for interventional studies. Readability ease and readability-grade level were assessed with Flesch-Kincaid scales. Results indicated higher readability grade-level 12.4 + 0.4 (P < 0.001) and lower readability Flesch-Kincaid reading ease score 35.7 + 3.6 for observational studies, as compared to 10.3 + 1.6 and 47.8 + 7.4 for interventional studies. Conclusion: Mandatory training for investigators is essential to provide readability ease and GCP compliance for the ICFs for the local population. PMID:27453828

    ABSTRACT Aims: Participation in family and recreational activities, self-care, and parent ease of caregiving are important outcomes for young children with cerebral palsy (CP). The aim of this study was to examine use of the Child Engagement in Daily Life and the Ease of Caregiving for Children to measure change over time. Methods: A convenience sample of 387 parents of young children with CP (18 months to 5 years of age) completed the measures twice, a mean of 12.7 months apart. Results: For the Child Engagement in Daily Life, parents of children in Gross Motor Function Classification System level I and levels II-III reported more change for the Self-care domain (medium effect) than the Family and Recreational Activities domain (small effect) and the Ease of Caregiving for Children (small effect). The change reported by parents of children in levels IV-V on all three measures was less than the criterion for a small effect. Minimal detectable change for each measure varied from 12.1 to 14.1, out of a total possible score of 100. Conclusion: Further research is recommended to determine responsiveness to change following intervention.

    Background Many patients with chronic obstructive pulmonary disease (COPD) achieve incomplete benefit from their treatment, due to reasons including inadequate device training or incorrect inhaler technique. Dosing frequency has also been shown to impact COPD treatment compliance with inhaler overuse and underuse being the most common form of noncompliance. Between 28–68% of patients do not use their inhalers correctly, and 39–67% of health care professionals (HCPs) do not effectively train patients to correctly use their inhalers. This makes patients prone to committing inhaler use errors and may negatively impact treatment compliance. We conducted a computer-assisted telephonic survey in patients with COPD to evaluate patient-reported insights on real life aspects of inhaler use, training and check for correct use by HCP, device attributes and patient-reported compliance of inhaler or medication use. Methods Patients from 9 countries, diagnosed with mild to very severe COPD and using maintenance inhaled treatment (via Breezhaler®, Ellipta®, Genuair®, Respimat®) were included in this survey. Patient-reported data on correct inhaler use (training and check), inhalation pattern, and device attributes (ease of use and confidence of inhaling full dose), compliance and potential underuse or overuse was collected. Chi-square test was performed for testing significance and z-test was used for comparisons of proportions (significance level: alpha<0.05). Results A total of 764 patients (Breezhaler® =186; Ellipta® =191; Genuair® = 194; Respimat® =201) with mild to very severe COPD with a mean (±SD) age 56±9.8 years, completed the survey. Approximately, 30% of all patients reported not receiving any inhaler use training. Of the 70%, who received training on inhaler use, 83% felt that the demonstration of inhaler use was very helpful, followed by videos (58%), instructions for use (51%) and leaflets (34%), irrespective of the device used.

  20. Viral Concentration Determination Through Plaque Assays: Using Traditional and Novel Overlay Systems

    PubMed Central

    Baer, Alan; Kehn-Hall, Kylene

    2014-01-01

    Plaque assays remain one of the most accurate methods for the direct quantification of infectious virons and antiviral substances through the counting of discrete plaques (infectious units and cellular dead zones) in cell culture. Here we demonstrate how to perform a basic plaque assay, and how differing overlays and techniques can affect plaque formation and production. Typically solid or semisolid overlay substrates, such as agarose or carboxymethyl cellulose, have been used to restrict viral spread, preventing indiscriminate infection through the liquid growth medium. Immobilized overlays restrict cellular infection to the immediately surrounding monolayer, allowing the formation of discrete countable foci and subsequent plaque formation. To overcome the difficulties inherent in using traditional overlays, a novel liquid overlay utilizing microcrystalline cellulose and carboxymethyl cellulose sodium has been increasingly used as a replacement in the standard plaque assay. Liquid overlay plaque assays can be readily performed in either standard 6 or 12 well plate formats as per traditional techniques and require no special equipment. Due to its liquid state and subsequent ease of application and removal, microculture plate formats may alternatively be utilized as a rapid, accurate and high throughput alternative to larger scale viral titrations. Use of a non heated viscous liquid polymer offers the opportunity to streamline work, conserves reagents, incubator space, and increases operational safety when used in traditional or high containment labs as no reagent heating or glassware are required. Liquid overlays may also prove more sensitive than traditional overlays for certain heat labile viruses. PMID:25407402

    The effect of calving ease on the fertility and production performance of both dam and calf was studied in approximately 50,000 and 10,000 UK Holstein-Friesian heifers and heifer calves, respectively. The first objective of this study was to estimate the effect of a difficult calving on the subsequent first-lactation milk production by estimating lactation curves using cubic splines. This methodology allows the estimation of daily milk, protein, and fat yields following calvings of differing degrees of difficulty. Losses in milk yield after a difficult calving have been quantified previously; however, estimates are generally restricted to the accumulated yields at specific days in lactation. By fitting cubic splines, gaps (in which the shape of the lactation curve can be merely guessed) between estimations were avoided. The second objective of this study was to estimate the effect of a difficult birth on the subsequent performance of the calf as an adult animal. Even though the calving process is known to involve cooperation between dam and calf, the effect of a difficult calving has, until now, only been estimated for the subsequent performance of the dam. Addressing the effects of a difficult birth on the adult calf strengthens the importance of calving ease as a selection trait because it suggests that the benefit of genetic improvement may currently be underestimated. The effect of calving ease on the subsequent reproductive performance of dam and calf was analyzed using linear regression and with calving ease score fitted as a fixed effect. Dams with veterinary-assisted calvings required 0.7 more services to conception and 8 more days to first service and experienced a 28-d longer calving interval in first lactation compared with dams that were not assisted at calving. Effects of calving ease on the reproductive performance of the adult calf in first lactation were not detected. Losses in milk yield of the dam were significant between d 9 to 90 in milk

    Full body gesture recognition is an important and interdisciplinary research field which is widely used in many application spheres including dance gesture recognition. The rapid growth of technology in recent years brought a lot of contribution in this domain. However it is still challenging task. In this paper we implement Kazakh traditional dance gesture recognition. We use Microsoft Kinect camera to obtain human skeleton and depth information. Then we apply tree-structured Bayesian network and Expectation Maximization algorithm with K-means clustering to calculate conditional linear Gaussians for classifying poses. And finally we use Hidden Markov Model to detect dance gestures. Our main contribution is that we extend Kinect skeleton by adding headwear as a new skeleton joint which is calculated from depth image. This novelty allows us to significantly improve the accuracy of head gesture recognition of a dancer which in turn plays considerable role in whole body gesture recognition. Experimental results show the efficiency of the proposed method and that its performance is comparable to the state-of-the-art system performances.

    This article complements the Rhinelander and Rubin article (this issue) and provides an account of US and USSR practice subsequent to the ABM Treaty. The Soviet subsequent practice from 1972 to date, like that of the US from 1972 until 1985, has fully supported the validity of the traditional interpretation, and explicitly rejected the reinterpretation, both before and after the reinterpretation was announced. The record is unambiguous. The Reagan administration's continued support of its radical reinterpretation of the ABM Treaty cannot be justified. In seeking to place the matter in perspective, one could do worse than apply the golden rule: what would the US have thought if after many years the USSR had suddenly, unilaterally, reinterpreted the ABM Treaty (or any other) to suit a policy purpose of its own, contrary to US policy and to the original clear understanding of both parties. What would the US have thought if the Soviets had then publicly acknowledged that they had done so without examining either their own ratification record of the record of the subsequent practice of the parties, without consulting any but one of their own negotiators, and before compiling much of their own relevant negotiating records.

    The Traditional Birth Attendants (TBAs) Survey in Swaziland was undertaken between March 27th 1996 and April 8th 1996. The objective of the survey was to generate reliable information regarding activities of TBAs in Swaziland. The survey was conducted in 25 Chiefdoms sampled out of a total of 206 Chiefdoms registered in Swaziland. The total number of sampled respondents in the 25 Chiefdoms was 721. From the survey, it is estimated that there were probably 3000 TBAs in the country, and in the majority of cases such TBAs would be a 51-year old woman who herself had delivered six children and had worked as a TBA for at least 10 years. Between 9,000 and 12,000 deliveries are estimated to take place out of health facilities. Of these many, nearly 43.5% are assisted by "TBAs"; 16.3% of woman interviewed deliver relative/family member and 15.1% are assisted by friends/neighbours, etc. Some of TBAs carry out procedures which are considered to be potentially harmful. Nearly 30% of TBAs have administered herbs; 45% attend to abnormal deliveries (breech and multiple pregnancies); 26.7% re-use their cord cutting tools and in the case of haemorrhage 23.4% do manual procedures within reproductive tract of delivering women.

    Background. The present study aimed to evaluate and compare the effect of two different types of Tai Chi programs on the Functional Movement Screening (FMS) in older adults. Methods. Ninety older adults (65.5 ± 4.6 years old) who met the eligibility criteria were randomized into three different groups based on a ratio of 1 : 1 : 1: a traditional Tai Chi exercise (TTC), a simplified Tai Chi exercise (TCRT), or a control group (routine activity). The FMS consisted of the deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg rise, trunk stability push-up, and rotatory stability, which was used to measure physical function before the present study and after six months of Tai Chi interventions. Results. Seventy-nine participants completed the present study (control = 27, TTC = 23, and TCRT = 29). Significant improvement on the FMS tests between the baseline and after the six-month intervention was observed in both Tai Chi programs, whereas no significant improvement was observed in the control group. In addition, participants in the TCRT group demonstrated greater improvement than those in the TTC group. Conclusions. The TCRT is more effective in improving the physical function in older adults when compared to the traditional Tai Chi modality, particularly for improving balance.

    Background. The present study aimed to evaluate and compare the effect of two different types of Tai Chi programs on the Functional Movement Screening (FMS) in older adults. Methods. Ninety older adults (65.5 ± 4.6 years old) who met the eligibility criteria were randomized into three different groups based on a ratio of 1 : 1 : 1: a traditional Tai Chi exercise (TTC), a simplified Tai Chi exercise (TCRT), or a control group (routine activity). The FMS consisted of the deep squat, hurdle step, in-line lunge, shoulder mobility, active straight leg rise, trunk stability push-up, and rotatory stability, which was used to measure physical function before the present study and after six months of Tai Chi interventions. Results. Seventy-nine participants completed the present study (control = 27, TTC = 23, and TCRT = 29). Significant improvement on the FMS tests between the baseline and after the six-month intervention was observed in both Tai Chi programs, whereas no significant improvement was observed in the control group. In addition, participants in the TCRT group demonstrated greater improvement than those in the TTC group. Conclusions. The TCRT is more effective in improving the physical function in older adults when compared to the traditional Tai Chi modality, particularly for improving balance. PMID:27956920

    Humans have tried to control fertility for centuries. Primitive, preliterate societies practiced infanticide and abortion. When primitive women understood the advantages of conception control, they tried, when possible, to use contraception. In the 4th century B.C., Plato and Aristotle advocated a one-child family. Greek medical literature reported a hollow tube inserted through the cervix into the uterus and a potion as contraceptives. Islamic physicians had much knowledge about conception control. The attitudes toward contraception. In the 5th century B.C., Saint Augustine condemned contraception, even among married couples. The condom emerged in the early modern period. Yet, they were usually worn to protect against disease, e.g., bilharzia in Egypt and syphilis in Europe. The cervical cap and the diaphragm are examples of occlusive pessaries. By 1880, contraceptives and spermicides were advertised. In 1928, the IUD joined the existing contraceptives. Today we have combined oral contraceptives. Judaic law requires husbands to fulfill their wives sexual needs, separate from their duty to procreate. It also calls men, not women, to procreate and forbids men from masturbating, thus Judaic law does not forbid women from practicing contraception. The Roman Catholic church forbids contraceptive use because it is a sin against nature. Some Protestant denominations have allowed contraceptive use. Islamic law states that children are gifts from Allah. Some Moslems believe that they must have many children, but Allah and the Prophet state that children have rights to education and future security. These rights allow couples to prevent pregnancy. Neither Hinduism nor Buddhism prohibit contraceptive use. Differences in husband-wife communication, sex roles, access to contraceptives, and traditional family values will have more of an effect on contraceptive use and fertility than theological barriers or the social class of religious groups.

  10. Need of the regulation for profit percentage investment by pharmaceutical companies in new drug discovery research from the various local traditional medicinal and plant systems.

    In the modern medical systems the active pharmacological ingredients, effective against any disease is identified, purified and studied for its various effects and side-effects whereas it is not so in the traditional systems. Therefore, it is not surprising that safety concerns have often been raised about the traditional medical products. The major issue now, is to make appropriate situation with basic supports to bring all the available experts and resources together for the identification, purification, and study of efficacy and safety of the active molecules of the popular traditional medicines. Government and public sectors in the countries with such rich traditional medicinal and plant systems have related experts, but they also have much hurdle regarding recruitment and retention of expert human resources, getting fund, purchase and maintenance of equipment, bureaucratic formalities and others. The pharmaceutical companies have basic laboratories with related infrastructure and human resources as well as interest about bringing the drug molecules. To bridge the gap, there is a need of the regulation which will make the pharmaceutical companies to invest certain percentage of their profit in the field of research to identify new drug molecules and to study their effects. It is just not an issue of discovering the active molecule but also of creating the concept and culture of research, purity and quality of drugs, safety of people, and future direction of the human society.

    Proteomics has the potential to elucidate the metabolic pathways and taxa responsible for in situ biogeochemical transformations. However, low rates of protein identification from high resolution mass spectra have been a barrier to the development of proteomics in complex environmental samples. Much of the difficulty lies in the computational challenge of linking mass spectra to their corresponding proteins. Traditional database search methods for matching peptide sequences to mass spectra are often inadequate due to the complexity of environmental proteomes and the large database search space, as we demonstrate with soil and sediment proteomes generated via a range of extraction methods. One alternative to traditional database searching is de novo sequencing, which identifies peptide sequences without the need for a database. BLAST can then be used to match de novo sequences to similar genetic sequences. Assigning confidence to putative identifications has been one hurdle for the implementation of de novo sequencing. We found that accurate de novo sequences can be screened by quality score and length. Screening criteria are verified by comparing the results of de novo sequencing and traditional database searching for well-characterized proteomes from simple biological systems. The BLAST hits of screened sequences are interrogated for taxonomic and functional information. We applied de novo sequencing to organic topsoil and marine sediment proteomes. Peak-rich proteomes, which can result from various extraction techniques, yield thousands of high-confidence protein identifications, an improvement over previous proteomic studies of soil and sediment. User-friendly software tools for de novo metaproteomics analysis have been developed. This "De Novo Analysis" Pipeline is also a faster method of data analysis than constructing a tailored sequence database for traditional database searching.

    Organophosphates may be used as weapons in chemical attacks on civilian or military populations. Antidotes are available to counter the effects of organophosphates, but they must be administered shortly after exposure. Timing required to administer organophosphate antidotes using traditional equipment vs. auto-injectors has not been studied. This study is intended to quantify and compare the time required to administer organophosphate antidotes using traditional equipment vs. auto-injectors in different treatment conditions. The study was a randomized, un-blinded design. There were 62 participants assigned to one of three groups: Mark I, ATNAA (antidote treatment nerve agent auto-injector), and traditional needle/syringe; however, the results from only 56 participants could be analyzed. Injection trials were videotaped. Subjects also completed a 14-item survey containing demographic questions, perceived ease of injection, receipt of prior training, and preferred training format for organophosphate treatment. Injection time differentials were compared using one-way analysis of variance; post hoc evaluation was performed using the Scheffe test with Bonferroni correction. Fifty-six subjects completed this study. The ATNAA required less time to administer than the Mark I or traditional needle/syringe devices (p < .001). There was no difference in time to administer the Mark I auto-injectors vs. a traditional needle/syringe. There were no differences between injection time and occupation, receipt of prior training, wearing of personal protective equipment, or perceived ease of injection device use. The use of auto-injectors shortens response time for administering organophosphate antidote treatment. An ATNAA auto-injector can be administered in less than half the time it takes to administer a single injection using a needle and syringe or two injections using a Mark I. Mark I can be administered in approximately the same amount of time it takes to administer a single

    Background Handheld inhalers are used to deliver treatment for COPD. Incorrect usage leads to suboptimal disease control. Complex treatment regimens and use of multiple inhalers may reduce patient compliance. The Anoro Ellipta™ dry powder inhaler (DPI) simultaneously delivers umeclidinium bromide (UMEC) and vilanterol (VI) without coformulation being required. Aim To assess the correct usage and ease of use of the Ellipta™ DPI administering UMEC/VI and to compare patient preference for Ellipta™ with the HandiHaler® through exploratory analyses of patient and observer questionnaires in five Phase III studies. Methods Two Phase III, 3-month double-blind, placebo-controlled studies assessed the correct usage of the Ellipta™ DPI at Day 1 and after 6 weeks, and ease of use of the Ellipta™ DPI using a nonvalidated patient questionnaire after 6 weeks or early withdrawal. In three 6-month, blinded double-dummy, active comparator studies (two Phase IIIa and one Phase IIIb), patients completed a COPD device preference questionnaire between the Ellipta™ DPI and the Handi-Haler® at Day 168 (Week 24) or early withdrawal. Results In the 3-month placebo-controlled studies, ≥98% of patients used the Ellipta™ DPI correctly and 99% of patients found the inhaler easy/very easy-to-use and the dose counter easy/very easy to read. Across the two Phase IIIa active comparator studies, patients consistently stated a preference for the Ellipta™ DPI over HandiHaler® regarding the number of steps to use (59% vs 17%), time taken to use (62% vs 14%), and ease of use (63% vs 15%) regardless of which inhaler contained active drug. Results were consistent in the Phase IIIb active comparator study. Conclusion Delivery of UMEC/VI via the Ellipta™ DPI was considered easy-to-use, and patients with COPD demonstrated clear preference for this inhaler compared with HandiHaler®. PMID:27578968

    Cancer is a serious and ever increasing problem in the United States Associated Pacific Islands (USAPIs). Nearly 30% of all consultations and referrals are for cancer. Depending on the type of cancer, the prognosis for long-term survival is often poor and the cost of caring for such patients is considerable. Tripler Army Medical Center (TAMC) provides tertiary medical care to patients from the USAPIs in support of Graduate Medical Education (GME) at no cost to the patient or jurisdiction. Continuing its tradition of leading telemedicine initiatives in the Pacific, TAMC has developed a web-based electronic consultation and referral network, the Pacific Island Health Care Project (PIHCP). Ten sites in Micronesia and one in American Samoa were provided with computer equipment. Local clinicians request consultation from TAMC specialists through the internet, attaching supporting imagery. The consults are posted on a secure web page, where they are viewed, evaluated, forwarded, and commented on by the consultants. Experience with more than 2,100 cases indicates that the Internet can be easily used as a store-and-forward consultation format and offers a cost effective means for distance consultation, referral, and learning. This format has provided for a more rational evaluation of all patients but especially patients with cancer. Patients who are terminally ill, have widely metastasized disease, and/or have inoperable tumors or recurrences are excluded so that limited resources can be used for those most likely to benefit. There has been overwhelming enthusiasm for such Internet consultations between referring physicians and consultants. Many Pacific Islander patients have received state-of-the-art medical care through this program. At the same time, the training of TAMC physicians and residents has been enhanced by their opportunity to care for these remarkable and deserving patients from the Pacific.

    Menorrhagia is a common problem. Medical management for menorrhagia includes hormonal and nonhormonal treatments. These treatments have different side effects, which reduce quality of life. Complementary and traditional medicines have been used to handle menorrhagia for centuries in many cultures. There is a lot of information and data in Iranian traditional documents or books about medicinal herbs that are used by Iranian traditional medicine scientists for the treatment of menorrhagia. The aim of this study was to review the approaches to menorrhagia in Iranian traditional medicine texts. In this study, some main Iranian traditional medicine manuscripts including Canon of Medicine and Al-Havi of Rhazes were studied to extract important information about menorrhagia management. Iranian traditional medicine physicians have relied on an organized system of etiological theories and treatments for menorrhagia. Their methods for menorrhagia management may be able to convince the desire of many women to preserve their uterus and avoid hormonal therapy.

    In recent literature on eternal inflation, a number of measures have been introduced which attempt to assign probabilities to different pocket universes by counting the number of each type of pocket according to a specific procedure. We give an overview of the existing measures, pointing out some interesting connections and generic predictions. For example, pairs of vacua that undergo fast transitions between themselves will be strongly favored. The resultant implications for making predictions in a generic potential landscape are discussed. We also raise a number of issues concerning the types of transitions that observers in eternal inflation are able to experience.

    Models provide useful insights into conservation and resource management issues and solutions. Their use to date has highlighted conditions under which no-take marine protected areas (MPAs) may help us to achieve the goals of ecosystem-based management by reducing pressures, and where they might fail to achieve desired goals. For example, static reserve designs are unlikely to achieve desired objectives when applied to mobile species or when compromised by climate-related ecosystem restructuring and range shifts. Modelling tools allow planners to explore a range of options, such as basing MPAs on the presence of dynamic oceanic features, and to evaluate the potential future impacts of alternative interventions compared with ‘no-action’ counterfactuals, under a range of environmental and development scenarios. The modelling environment allows the analyst to test if indicators and management strategies are robust to uncertainties in how the ecosystem (and the broader human–ecosystem combination) operates, including the direct and indirect ecological effects of protection. Moreover, modelling results can be presented at multiple spatial and temporal scales, and relative to ecological, economic and social objectives. This helps to reveal potential ‘surprises', such as regime shifts, trophic cascades and bottlenecks in human responses. Using illustrative examples, this paper briefly covers the history of the use of simulation models for evaluating MPA options, and discusses their utility and limitations for informing protected area management in the marine realm.

    Aims. This study assesses the impact of using an AP-system at home on fear of hypoglycaemia. In addition, satisfaction and acceptance of the new technology are evaluated. Methods. In a multicentre, multinational study of 75 patients using the MD-Logic AP during four consecutive nights in home setting 59 of them (aged 10–54 years, 54% male, HbA1c 7.89 ± 0.69% [62.72 ± 7.51 mmol/mol], diabetes duration 11.6 ± 8.4 yrs) answered standardized questionnaires (HFS, adapted TAM, and AP satisfaction) before and after using the AP. Results. After experiencing the AP in home setting worries of hypoglycaemia were significantly reduced (before 1.04 ± 0.53 versus after 0.90 ± 0.63; P = 0.017). Perceived ease of use as a measure of acceptance with the AP significantly increased after personal experience (before 4.64 ± 0.94 versus after 5.06 ± 1.09; P = 0.002). The overall satisfaction mean score after using the AP was 3.02 ± 0.54 (range 0–4), demonstrating a high level of satisfaction with this technology. Conclusions. The four-night home-based experience of using MD Logic AP was associated with reduced worries of hypoglycaemia, high level of satisfaction, and increased perceived ease of use of the new technology in children, adolescents, and adults.

    Surface properties of lens cases are determinant for their cleanability and for microbial transmission from lens cases to contact lenses (CLs). PEG-polymer-brush-coatings are known to decrease microbial adhesion more than other surface-coatings. Here, we applied a robust, silica nanoparticles-based brush-coating to polypropylene cases to evaluate their ease of cleaning and probability of bacterial transmission to CLs. Adhesion forces of nine bacterial strains (Pseudomonas, Staphylococci, and Serratia) to rigid CLs, polypropylene, and silica nanoparticles-based brush-coated polypropylene were measured using atomic-force-microscopy and subjected to Weibull analyses to yield bacterial transmission probabilities. Biofilms of each strain were grown in coated and uncoated cases and rinsed with a NaCl or antimicrobial lens care solution. Residual, viable organisms were quantified. Bacterial adhesion forces of all strains were significantly, up to tenfold smaller on brush-coated than on uncoated polypropylene. This yielded, higher transmission probabilities to a CL, but mild-rinsing yielded 10-100 fold higher removal of bacteria from brush-coated than from polypropylene cases. Moreover, due to weak adhesion forces, bacteria on brush-coated cases were two-to-three fold more susceptible to an antimicrobial lens care solution than on polypropylene cases. Therewith, the design of lens case surfaces is a compromise between ease of cleaning and transmission probability to CLs.

    Inhaler errors are common amongst inhaler users. Therefore, in the development work of new inhalation devices, it is important to characterize the ease of use of the inhalers. In this study four dry powder inhalers, Diskus, Easyhaler, Ellipta and Turbuhaler, were evaluated, focusing on ease of use and patient preference. The study used a triangular methodology. The sample consisted of 31 inhaler naïve individuals. Educational videos for all inhalers were watched, and afterwards, the use of all four inhalers was demonstrated in a random order. The demonstrations were videotaped. Thereafter they were checked against a predefined checklist and all mistakes were recorded. Only 33% of inhaler demonstrations were completed without the participants making any mistakes. The proportions of subjects who used the devices correctly were as follows: Diskus 48%, Easyhaler 19%, Ellipta 55% and Turbuhaler 16%. When comparing correct and incorrect inhaler technique for each inhaler pair the following differences were statistically significant: Diskus vs. Easyhaler (p<0.05), Ellipta vs. Easyhaler (p<0.01), Diskus vs. Turbuhaler (p<0.01), Ellipta vs. Turbuhaler (p<0.01). In the participants' ranking, the inhalers Ellipta, followed by Turbuhaler, were most often ranked as most preferred. Participants' preference of Ellipta over Easyhaler (p<0.01) and over Diskus (p<0.001) were statistically significant.

    Novae and supernovae are rare astronomical events that would have had an influence on the skywatching peoples who witnessed them. Although several bright novae/supernovae have been visible during recorded human history, there are many proposed but no confirmed accounts of supernovae in indigenous oral traditions or material culture. Criteria are established for confirming novae/supernovae in oral traditions and material culture, and claims from around the world are discussed to determine if they meet these criteria. Aboriginal Australian traditions are explored for possible descriptions of novae/supernovae. Although representations of supernovae may exist in Aboriginal traditions, there are currently no confirmed accounts of supernovae in Indigenous Australian oral or material traditions.

    Nanoparticulation of insoluble drugs improves dissolution rate, resulting in increased bioavailability that leads to increased stability, better efficacy, and reduced toxicity of drugs. Docetaxel (DTX), under the trade name Taxotere™, is one of the representative anticancer chemotherapeutic agents of this era. However, this highly lipophilic and insoluble drug has many adverse effects. Our novel and widely applicable nanoparticulation using fat and supercritical fluid (NUFS™) technology enabled successful nanoscale particulation of DTX (Nufs-DTX). Nufs-DTX showed enhanced dissolution rate and increased aqueous stability in water. After confirming the preserved mechanism of action of DTX, which targets microtubules, we showed that Nufs-DTX exhibited similar effects in proliferation and clonogenic assays using A549 cells. Interestingly, we observed that Nufs-DTX had a greater in vivo tumor growth delay effect on an A549 xenograft model than Taxotere™, which was in agreement with the improved drug accumulation in tumors according to the biodistribution result, and was caused by the enhanced permeability and retention (EPR) effect. Although both Nufs-DTX and Taxotere™ showed negative results for our administration dose in the hematologic toxicity test, Nufs-DTX showed much less toxicity than Taxotere™ in edema, paralysis, and paw-withdrawal latency on a hot plate analysis that are regarded as indicators of fluid retention, peripheral neuropathy, and thermal threshold, respectively, for toxicological tests. In summary, compared with Taxotere™, Nufs-DTX, which was generated by our new platform technology using lipid, supercritical fluid, and carbon dioxide (CO2), maintained its biochemical properties as a cytotoxic agent and had better tumor targeting ability, better in vivo therapeutic effect, and less toxicity, thereby overcoming the current hurdles of traditional drugs.

    As a form of traditional, complementary, and alternative medicine (TCAM), traditional Tibetan medicine has developed into a mainstay of medical care in Tibet and has spread from there to China and then to the rest of the world. Thus far, research on traditional Tibetan medicine has focused on the study of the plant and animal sources of traditional medicines, study of the histology of those plants and animals, chemical analysis of traditional medicines, pharmacological study of those medicines, and evaluation of the clinical efficacy of those medicines. A number of papers on traditional Tibetan medicines have been published, providing some evidence of the efficacy of traditional Tibetan medicine. However, many traditional Tibetan medicines have unknown active ingredients, hampering the establishment of drug quality standards, the development of new medicines, commercial production of medicines, and market availability of those medicines. Traditional Tibetan medicine must take several steps to modernize and spread to the rest of the world: the pharmacodynamics of traditional Tibetan medicines need to be determined, the clinical efficacy of those medicines needs to be verified, criteria to evaluate the efficacy of those medicines need to be established in order to guide their clinical use, and efficacious medicines need to be acknowledged by the pharmaceutical market. The components of traditional Tibetan medicine should be studied, traditional Tibetan medicines should be screened for their active ingredients, and techniques should be devised to prepare and manufacture those medicines.

    Close adherence to the recommended treatment regimen is important for the success of recombinant human growth hormone therapy, although nonadherence can be common. Ease of use and safety during use/storage are among several important factors in the design of a growth hormone injection device intended for long-term use. This study was performed to validate the usability and assess the ease of use of a new pen device (SurePal™) that has been developed to support daily administration of the recombinant human growth hormone product, Omnitrope® (somatropin). The primary objectives of the study were to assess if study participants, representing intended users of the pen in clinical practice, were able to perform an injection procedure into an injection pad effectively and safely and disassemble the pen without receiving a needlestick injury. A total of 106 participants (61 adults and 45 children/adolescents) were enrolled at two study centers (one in the US, one in Germany). Results for both primary usability tasks met the predefined acceptance criteria, with >85% of participants successfully performing each task. All of the other tasks/handling steps assessed were also successfully performed by most participants, with high success rates reflected in the high proportion of participants who classified each task as "very easy" or "easy". After a second use of the device, 87%-97% of participants rated it as "very easy" or "easy" to use. In summary, the new pen device is safe and easy to use for both adults and children, and will help to support effective, long-term daily administration of the recombinant human growth hormone product, Omnitrope®.

    Context: Laryngeal mask airway (LMA) Classic™ has an inflatable cuff while i-gel™ has a noninflatable cuff made of thermoplastic elastomer. Aims: To compare ease of insertion, number, and duration of insertion attempts among the two device. Secondary objectives were to evaluate the hemodynamic response and SpO2 during device insertion and during maintenance of general anesthesia. Settings and Design: This study was conducted as randomized observational study in a teaching hospital. Subjects and Methods: One hundred American Society of Anesthesiologists I and II, patients posted for surgery under general anesthesia were divided in two groups of fifty each. LMA Classic™ and i-gel™. Ease of insertion, duration of insertion, hemodynamic data, and episodes of hypoxia during insertion, 1, 3 and 5 min for 30 min, during removal and 1 min after removal. Statistical Analysis Used: Descriptive analyses were expressed as a mean ± standard deviation. Independent t-test used for parametric data, Chi-square test for nonparametric data and hemodynamic data were analyzed using repeated measures ANOVA to find statistical difference within the groups. Results: Devices were easy to insert, the mean duration of insertion attempts was 15.92 ± 1.62 s in the i-gel™ group, while it was 26.06 ± 5.12 s in the LMA Classic™ group, was statistically significant (P = 0.0001). Conclusions: Successful and shorter duration of insertion, with less hemodynamic response makes i-gel™ a suitable alternative to LMA Classic™ during general anesthesia. PMID:27746545

    Providing a natural mapping between multi-touch gestures and manipulations of digital content is important for user-friendly interfaces. Although there are some guidelines for 2D digital content available in the literature, a guideline for manipulation of 3D content has yet to be developed. In this research, two sets of gestures were developed for experiments in the ease of manipulating 3D content on a touchscreen. As there typically are large differences between age groups in the ease of learning new interfaces, we compared a group of adults with a group of children. Each person carried out three tasks linked to rotating the digital model of a green turtle to inspect major characteristics of its body. Task completion time, subjective evaluations, and gesture changing frequency were measured. Results showed that using the conventional gestures for 2D object rotation was not appropriate in the 3D environment. Gestures that required multiple touch points hampered the real-time visibility of rotational effects on a large screen. While the cumulative effects of 3D rotations became complicated after intensive operations, simpler gestures facilitated the mapping between 2D control movements and 3D content displays. For rotation in Cartesian coordinates, moving one fingertip horizontally or vertically on a 2D touchscreen corresponded to the rotation angles of two axes for 3D content, while the relative movement between two fingertips was used to control the rotation angleof the third axis. Based on behavior analysis, adults and children differed in the diversity of gesture types and in the touch points with respect to the object's contours. Offering a robust mechanism for gestural inputs is necessary for universal control of such a system.

  17. Perinatal Practices & Traditions Among Asian Indian Women.

    2016-01-01

    As the population in the United States grows more diverse, nurses caring for childbearing women must be aware of the many cultural traditions and customs unique to their patients. This knowledge and insight supports women and their families with the appropriate care, information, and resources. A supportive relationship builds trust, offers guidance, and allows for the new family to integrate information from nurses and other healthcare providers with the practice of certain perinatal cultural traditions. The Asian Indian culture is rich in tradition, specifically during the perinatal period. To support the cultural beliefs and practices of Asian Indian women during this time, nurses need to be aware of and consider multiple factors. Many women are navigating the new role of motherhood while making sense of and incorporating important cultural rituals. The purpose of this article is to provide an overview of perinatal cultural practices and traditions specific to the Asian Indian culture that perinatal nurses may observe in the clinical setting. Cultural traditions and practices specific to the pregnancy and postpartum period are described together with symbolism and implications for nursing practice. It is important to note that information regarding perinatal customs is provided in an effort to promote culturally sensitive nursing care and may not pertain to all Asian Indian women living in the United States.

  18. Welfare of non-traditional pets.

    PubMed

    Schuppli, C A; Fraser, D; Bacon, H J

    2014-04-01

    The keeping of non-traditional or 'exotic' pets has been growing in popularity worldwide. In addition to the typical welfare challenges of keeping more traditional pet species like dogs and cats, ensuring the welfare of non-traditional pets is complicated by factors such as lack of knowledge, difficulties meeting requirements in the home and where and how animals are obtained. This paper uses examples of different species to highlight three major welfare concerns: ensuring that pets under our care i) function well biologically, ii) are free from negative psychological states and able to experience normal pleasures, and iii) lead reasonably natural lives. The keeping of non-traditional pets also raises ethical concerns about whether the animal poses any danger to others (e.g. transmission of zoonotic diseases) and whether the animal might cause environmental damage (e.g. invading non-native habitats when released). The authors used these considerations to create a checklist, which identifies and organises the various concerns that may arise over keeping non-traditional species as pets. An inability to address these concerns raises questions about how to mitigate them or even whether or not certain species should be kept as pets at all. Thus, the authors propose five categories, which range from relatively unproblematic pet species to species whose keeping poses unacceptable risks to the animals, to humans, or to the environment. This approach to the evaluation and categorisation of species could provide a constructive basis for advocacy and regulatory actions.

    Indian traditional staple and snack food is typically a heterogeneous recipe that incorporates varieties of vegetables, lentils and other ingredients. Modelling the retorting process of multilayer pouch packed Indian food was achieved using lumped-parameter approach. A unified model is proposed to estimate cold point temperature. Initial process conditions, retort temperature and % solid content were the significantly affecting independent variables. A model was developed using combination of vegetable solids and water, which was then validated using four traditional Indian vegetarian products: Pulav (steamed rice with vegetables), Sambar (south Indian style curry containing mixed vegetables and lentils), Gajar Halawa (carrot based sweet product) and Upama (wheat based snack product). The predicted and experimental values of temperature profile matched with ±10 % error which is a good match considering the food was a multi component system. Thus the model will be useful as a tool to reduce number of trials required to optimize retorting of various Indian traditional vegetarian foods.

    This study was conducted to determine nurses' and postpartum women's knowledge of and attitudes toward the traditional Chinese custom of 1-month confinement following delivery, to discover factors influencing the attitudes, and to analyze the correlation between them. After a descriptive and inferential analysis of 173 questionnaires (121 recent mothers and 52 nurses), a significant difference was found in the women's and nurses' scores for knowledge of the postpartum confinement custom, with postpartum women scoring higher than the nursing staff on average. Both groups held positive attitudes toward the traditional custom. Attitudes and level of knowledge were positively correlated. Results of this study can serve as a reference for in-service nursing education, which should include information about traditional postpartum customs.

    For most of the past 200 years, pterosaurs have been reconstructed with wing membranes attached to both the forelimbs and hindlimbs and with a quadrupedal stance and gait when grounded. In the early 1980s, this traditional model was replaced by a new design with narrow, stiff wings confined to the forelimbs and an upright, bipedal, digitigrade stance and gait. However, new studies of complete, uncrushed skeletal remains, well preserved wing membranes and extensive new pterosaur tracks, combined with reanalysis of the relationships of pterosaurs to other reptiles, suggest that a return to the traditional model is now overdue.

    2010-01-01

    Although the history of cheesemaking in the United States tells largely a tale of industrialization, there is a submerged yet continuous history of small-batch, hands-on, artisan cheese manufacture. This tradition, carried on in artisan cheese factories across the country, although concentrated in Wisconsin, is often overlooked by a new generation of artisan cheesemakers. Continuities in fabrication methods shared by preindustrial and post-industrial artisan creameries have been obscured by changes in the organization and significance of artisan production over the last one hundred years. Making cheese by hand has morphed from chore to occupation to vocation; from economic trade to expressive endeavor; from a craft to an art. American artisan cheesemaking tradition was invented and reinvented as a tradition of innovation. Indeed, ideological commitment to innovation as modern, progressive, American—and thus a marketable value—further obscures continuities between past and present, artisan factories, and new farmstead production. The social disconnect between the current artisan movement and American's enduring cheesemaking tradition reproduces class hierarchies even as it reflects growing equity in gendered occupational opportunities.

    Objectives: To review the existing techniques for minor salivary gland biopsy (MSGB) in the lip and to suggest a new approach to ease the procedure and reduce post-operative complications. Study Design: A comprehensive literature review and a descriptive study of a new surgical technique. Results: Diverse incisions have been suggested for MSGB with different designs (ellipse, circular, linear), different directions (parallel, oblique, vertical) and a wide range of lengths (from 1 mm up to 3 cm), but no comparative studies supporting the advantages of a particular type of incision over the others could be retrieved. A variety of features of the existing techniques for MSGB are linked to undesired events and surgical complications which could be minimized by modifying certain aspects of these procedures. The technique described, together with the use of the S forceps, represents a significant improvement over the already described chalazion forceps because it allows for a better access and positioning of the lower lip, improves the ergonomic conditions of the assistant, and facilitates the identification of lip areas with more superficial gland lobules. Conclusions: The suggested approach for lip MSGB includes a specifically designed instrument whose performance during lip biopsy may contribute to minimize post-operative complications. Key words:Sjögren’s syndrome, diagnosis, minor salivary gland biopsy, surgical technique, lower lip. PMID:23986014

    Traditional and nontraditional methods for machining organic-matrix and metal-matrix composites are reviewed. Such traditional procedures as drilling, cutting, sawing, routing, and grinding are discussed together with the damage introduced into composites by these manipulations. Particular attention is given to new, nontraditional methods, including laser, water-jet, electrodischarge, electrochemical spark, and ultrasonic machining methods showing that, these methods often speed up cutting and improve the surface quality. Moreover, it is sometimes possible to use new methods in cases where traditional methods are ineffective.

  12. Religious Traditions and Prenatal Genetic Counseling

    PubMed Central

    Anderson, Rebecca Rae

    2009-01-01

    Members of organized religious groups may look to their faith traditions for guidance regarding the moral implications of prenatal diagnosis and intervention. Many denominations have doctrinal statements relevant to these deliberations. In this paper, common spiritual issues arising in the genetic counseling encounter are described. Representative doctrinal positions, derived from the responses of 31 U.S. religious denominations to a survey relating to prenatal genetic counseling, are given. Because the long-term adjustment of patients may be dependent in part on their ability to reconcile their actions with their faith traditions, genetic counselors best serve their patients when they invite discussion of matters of faith. Unless invited, patients may assume these topics are ‘off limits’ or that care providers are indifferent to their beliefs. Although genetics professionals ought not assume the role of spiritual advisor, a working knowledge of doctrinal approaches should help counselors frame the issues, and avoid missteps. PMID:19170093

    2006-01-01

    Herbal remedies are widely used for the treatment and prevention of various diseases and often contain highly active pharmacological compounds. Many medicinal herbs and pharmaceutical drugs are therapeutic at one dose and toxic at another. Toxicity related to traditional medicines is becoming more widely recognized as these remedies become popular in the Mediterranean region as well as worldwide. Most reports concerning the toxic effects of herbal medicines are associated with hepatotoxicity although reports of other toxic effects including kidney, nervous system, blood, cardiovascular and dermatologic effects, mutagenicity and carcinogenicity have also been published in the medical literature. This article presents a systematic review on safety of traditional Arab medicine and the contribution of Arab scholars to toxicology. Use of modern cell biological, biochemical, in vitro and in vivo techniques for the evaluation of medicinal plants safety is also discussed. PMID:17173106

    2011-09-01

    Judaism has many traditions, customs, rules, and laws, which relate to the proper and ethical disposition of a decedent when a Medical Examiner/ Coroner is involved. In almost all United States jurisdictions, statutes mandate the need to determine the cause and manner of death (Coroners' Act PA Pl. 323, num. 130, section 1237). This article is a review of some religious writings, legal precedents, and forensic authorities, which may help to assist the Medical Examiner/Coroner when confronted with a Jewish decedent. There can be flexibility as to the extent that such forensic studies can and should be performed. The final consent and interpretation of the rules, laws, traditions, and customs will rest with the courts and local rabbinic authority.

  15. Seaweed cultivation: Traditional way and its reformation

    NASA Astrophysics Data System (ADS)

    Fei, Xiu-Geng; Bao, Ying; Lu, Shan

    1999-09-01

    Seaweed cultivation or phycoculture has been developed rather fast in recent years. The total production of cultivated seaweed at present is about 6250×103 tons fresh weight. The total cultivation area is estimated as 200×103 hectare. The annual total value of cultivated seaweeds has been estimated to be more than 3 billion US dollars. Phycoculture provides many job opportunities for the coastal region people, has the potential to improve marine environments and thus even induce global change. All traditional cultivation methods and techniques are based on or start from the individual plant or the cultivated seaweed population. Modern biological science and biotechnology achievements have benefited agriculture a lot, but traditional seaweed cultivation has not changed much since its founding. This is because seaweed cultivation has been quite conservative for quite a long period and has accumulated many problems requiring solution. Four main problems might be the most universal ones holding back further development of the industry. New ways of seaweed cultivation must be developed, new techniques must be perfected, and new problems solved. This paper mainly discusses the main problems of traditional seaweed cultivation at present and its possible further development and reformation in the future.

    Indonesia is one country that is highly prone to earthquakes because it is located at the juncture of four tectonic plates, namely the Asian continental shelf, the continental shelf of Australia, the Indian Ocean plate and the Pacific plate. In the southern and eastern parts of Indonesia there is a volcanic belt that extends from the island of Sumatra, Java and Nusa south eastern Sulawesi, the sides in the form of old volcanic mountains and the lowlands are mostly dominated by swamps. The condition of potential and proneness to disasters such as volcanic eruptions, earthquakes, tsunamis, floods, and landslides. Indonesian society have a local knowledge for facing disasters. Local communities in particular areas have local knowledge for facing disasters. Such knowledge is commonly kept by members of the communities and applied to their environments, including houses. This research aims to describe disaster-friendly Sundanese traditional building construction. It employs the evaluation method, by comparing Sundanese traditional house construction to the standards of disaster-friendly construction. The results indicate that the Sundanese traditional building constructions have been qualified as disaster-friendly buildings.

  17. Imitation and traditions in wild banded mongooses.

    PubMed

    Müller, Corsin A; Cant, Michael A

    2010-07-13

    Evidence has accumulated in recent years indicating that traditions are not a unique feature of human societies but may be common in primates and some other mammals. However, most documented cases remain contentious because observational studies of free-living animals suffer from interpretive weaknesses, whereas social diffusion experiments performed in captivity may not reflect conditions found in nature. Here we use experiments under natural conditions to demonstrate that wild banded mongooses (Mungos mungo) pass preferences for one of two possible foraging techniques on to the next generation through contextual imitation. Notably, both techniques coexisted within the same groups and were transmitted concurrently between adults and pups, which form close one-to-one associations during the period of pup dependency. This experimental demonstration of a foraging tradition in wild mammals provides critical evidence to support previous accounts of traditions in nonhuman animals based on distribution patterns of natural behaviors. Moreover, our data provide the first experimental demonstration of imitation in wild mammals and, contrary to common assumption, show that social learning need not lead to an increased behavioral homogeneity within groups.

    Holstein (HH), Jersey (JJ), and crosses of these breeds were mated to HH or JJ bulls to form purebreds, reciprocal crosses, backcrosses, and other crosses in a rotational mating system. The herd was located at the Center for Environmental Farming Systems in Goldsboro, North Carolina. Data for calf birth weight (CBW), calving ease (0 for unassisted, n=1,135, and 1 for assisted, n=96), and neonatal calf mortality (0 for alive, n=1,150, and 1 for abortions recorded after mid-gestation, stillborn, and dead within 48 h, n=81) of calves (n=1,231) were recorded over 9 calving seasons from 2003 through 2011. Gestation length (GL) was calculated as the number of days from last insemination to calving. Linear mixed models for CBW and GL included fixed effects of sex, parity (first vs. later parities), twin status, and 6 genetic groups: HH, JJ, reciprocal F(1) crosses (HJ, JH), crosses >50% Holsteins (HX) and crosses >50% Jerseys (JX), where sire breed is listed first. The CBW model also included GL as a covariate. Logistic regression for calving ease and neonatal calf mortality included fixed effects of sex, parity, and genetic group. Genetic groups were replaced by linear regression using percentage of HH genes as coefficients on the above models and included as covariates to determine various genetic effects. Year and dam were included as random effects in all models. Female calves (27.57±0.54 kg), twins (26.39±1.0 kg), and calves born to first-parity cows (27.67±0.56 kg) had lower CBW than respective male calves (29.53±0.53 kg), single births (30.71±0.19 kg), or calves born to multiparous cows (29.43±0.52 kg). Differences in genetic groups were observed for CBW and GL. Increased HH percentage in the calf increased CBW (+9.3±0.57 kg for HH vs. JJ calves), and increased HH percentage in the dams increased CBW (+1.71±0.53 kg for calves from HH dams vs. JJ dams); JH calves weighed 1.33 kg more than reciprocal HJ calves. Shorter GL was observed for twin births (272.6

    The aim of this study was to compare the effects of two parturition induction protocols with a nontreated control group, on interval to calving, calving ease, postpartum uterine health, and ovarian cyclicity in beef heifers. At Day 285 of gestation, 81 crossbred recipient beef heifers carrying purebred Simmental fetuses, were blocked by live-weight, body condition score, expected calving date and fetal sex, and assigned to one of three groups: (1) control (CON; no induction treatment, n = 29); (2) induction with corticosteroids (CORT; n = 27); or (3) induction with corticosteroids plus prostaglandin (CORT + PG; n = 25). Interval from induction to calving in hours and calving ease on a scale of 1 to 5 were recorded. Vaginal mucus samples were collected on Day 21 and Day 42 after calving (Day 0) by means of a Metricheck and scored on a scale of 0 to 3. Reproductive tract examinations were conducted on Day 21 and Day 42 after calving, and uterine cytology samples were obtained on Day 21. A positive cytologic sample was defined as greater than 18% neutrophils in the sample obtained via a cytobrush technique. Cows were considered to have resumed ovarian cyclicity if the presence of the CL was confirmed. Data were analyzed using the Mixed (normally distributed data) and Genmod (nonparametric data) procedures of SAS (v. 9.3). The interval from treatment to calving was longer (P < 0.0001) for CON (161.9 ± 15.12 hours) animals compared with CORT (39.7 ± 11.64 hours) or CORT + PG (32.6 ± 12.10 hours), which did not differ. Treatment did not affect calving difficulty score. There was also no difference in incidence of retained placenta between the three groups. At Day 21 postpartum, cytology score tended to be higher for both induced groups (48%) compared with the control animals (24%), but this was not the case for vaginal mucus score (CON 52%, CORT 70%, and CORT + PG 52%). A higher proportion of CON had an involuted uterus by Day 21 postpartum (69

    Introduction Hemophilia A treatment involves replacing the deficient coagulation factor VIII. This process may involve multiple steps that might create a barrier to adherence. A new dual-chamber syringe (DCS; FuseNGo®) was recently introduced with the aim of simplifying reconstitution. Aim This study aimed to identify factors associated with adult patients’ preferences for different coagulation factor VIII reconstitution systems and to test ease of use and patient preference for the DCS. Methods A cross-sectional survey of adults with hemophilia A in five European countries was conducted; a subset of subjects also participated in a practical testing session of the DCS. Results Among the 299 survey participants, the device scenario requiring the least equipment and reconstitution steps (the DCS) received a median preference rating of 71 out of 100 (0 being “the least desirable” and 100 “the most desirable” rating). This was significantly higher than the other scenarios (the next highest achieved a median of 50 points; P<0.001). Participants would be more likely to use this device prophylactically (P<0.001). Among the 98 participants who tested the DCS, 57% preferred this device over their current device, 26% preferred their current device, and 17% had no preference. The DCS was rated as easier to use than current treatment devices (median score 9/10 versus 7/10 for current treatment, P=0.001). Conclusion The survey indicates that the prefilled DCS, FuseNGo®, requiring the least equipment and fewest reconstitution steps, was preferred by patients and was the device most likely to be used prophylactically; the practical device testing supports these results.

    Underspecified user needs and frequent lack of a gold standard reference are typical barriers to technology evaluation. To address this problem, this paper presents a two-phase evaluation framework involving usability experts (phase 1) and end-users (phase 2). In phase 1, a cross-system functionality alignment between expert-derived user needs and system functions was performed to inform the choice of "the best available" comparison system to enable a cognitive walkthrough in phase 1 and a comparative effectiveness evaluation in phase 2. During phase 2, five quantitative and qualitative evaluation methods are mixed to assess usability: time-motion analysis, software log, questionnaires - System Usability Scale and the Unified Theory of Acceptance of Use of Technology, think-aloud protocols, and unstructured interviews. Each method contributes data for a unique measure (e.g., time motion analysis contributes task-completion-time; software log contributes action transition frequency). The measures are triangulated to yield complementary insights regarding user-perceived ease-of-use, functionality integration, anxiety during use, and workflow impact. To illustrate its use, we applied this framework in a formative evaluation of a software called Integrated Model for Patient Care and Clinical Trials (IMPACT). We conclude that this mixed-methods evaluation framework enables an integrated assessment of user needs satisfaction and user-perceived usefulness and usability of a novel design. This evaluation framework effectively bridges the gap between co-evolving user needs and technology designs during iterative prototyping and is particularly useful when it is difficult for users to articulate their needs for technology support due to the lack of a baseline.

XRD and Raman spectra indicated that the highly crystalline anatase TiO2 phase and monoclinic and triclinic of WO3 were formed. The mesoporous TiO2 exhibits large pore volumes of 0.267cm(3)g-1 and high surface areas of 180m(2)g(-1) but they become reduced to 0.221cm(3)g(-1) and 113m(2)g(-1), respectively upon WO3 incorporation, with tunable mesopore diameter in the range of 5-6.5nm. TEM images show WO3-TiO2 nanocomposites are quite uniform with 10-15nm of TiO2 and 5-10nm of WO3 sizes. Under UV illumination, the overall photocatalytic efficiency of the 3% WO3-TiO2 nanocomposite is 3.5 and 6.6 times higher than that of mesoporous TiO2 and commercial UV-100 photocatalyst, respectively. The 3% WO3-TiO2 nanocomposite is considered to be the optimum photocatalyst which is able to degrade completely (100% conversion) of imazapyr herbicide along 120min with high photonic efficiency ∼8%. While under visible light illumination, the 0.5% WO3-TiO2 nanocomposite is the optimum photocatalyst which achieves 46% photocatalytic efficiency.

    Purpose To examine the psychometric properties of the Injection Pen Assessment Questionnaire (IPAQ) including the following: 1) item and scale characteristics (e.g., frequencies, item distributions, and factor structure), 2) reliability, and 3) validity. Methods Focus groups and one-on-one dyad interviews guided the development of the IPAQ. The IPAQ was subsequently tested in 136 parent–child dyads in a Phase 3, 2-month, open-label, multicenter trial for a new Genotropin® disposable pen. Factor analysis was performed to inform the development of a scoring algorithm, and reliability and validity of the IPAQ were evaluated using the data from this two months study. Psychometric analyses were conducted separately for each injection pen. Results Confirmatory factor analysis provides evidence supporting a second order factor solution for four subscales and a total IPAQ score. These factor analysis results support the conceptual framework developed from previous qualitative research in patient dyads using the reusable pen. However, the IPAQ subscales did not consistently meet acceptable internal consistency reliability for some group level comparisons. Cronbach’s alphas for the total IPAQ score for both pens were 0.85, exceeding acceptable levels of reliability for group comparisons. Conclusions The total IPAQ score is a useful measure for evaluating ease of use and preference for injection pens in clinical trials among patient dyads receiving hGH. The psychometric properties of the individual subscales, mainly the lower internal consistency reliability of some of the subscales and the predictive validity findings, do not support the use of subscale scores alone as a primary endpoint.

    Underspecified user needs and frequent lack of a gold standard reference are typical barriers to technology evaluation. To address this problem, this paper presents a two-phase evaluation framework involving usability experts (phase 1) and end-users (phase 2). In phase 1, a cross-system functionality alignment between expert-derived user needs and system functions was performed to inform the choice of “the best available” comparison system to enable a cognitive walkthrough in phase 1 and a comparative effectiveness evaluation in phase 2. During phase 2, five quantitative and qualitative evaluation methods are mixed to assess usability: time-motion analysis, software log, questionnaires – System Usability Scale and the Unified Theory of Acceptance of Use of Technology, think-aloud protocols, and unstructured interviews. Each method contributes data for a unique measure (e.g., time motion analysis contributes task-completion-time; software log contributes action transition frequency). The measures are triangulated to yield complementary insights regarding user-perceived ease-of-use, functionality integration, anxiety during use, and workflow impact. To illustrate its use, we applied this framework in a formative evaluation of a software called Integrated Model for Patient Care and Clinical Trials (IMPACT). We conclude that this mixed-methods evaluation framework enables an integrated assessment of user needs satisfaction and user-perceived usefulness and usability of a novel design. This evaluation framework effectively bridges the gap between co-evolving user needs and technology designs during iterative prototyping and is particularly useful when it is difficult for users to articulate their needs for technology support due to the lack of a baseline.

    Significance: The regeneration of healthy and functional skin remains a huge challenge due to its multilayer structure and the presence of different cell types within the extracellular matrix in an organized way. Despite recent advances in wound care products, traditional therapies based on natural origin compounds, such as plant extracts, honey, and larvae, are interesting alternatives. These therapies offer new possibilities for the treatment of skin diseases, enhancing the access to the healthcare, and allowing overcoming some limitations associated to the modern products and therapies, such as the high costs, the long manufacturing times, and the increase in the bacterial resistance. This article gives a general overview about the recent advances in traditional therapies for skin wound healing, focusing on the therapeutic activity, action mechanisms, and clinical trials of the most commonly used natural compounds. New insights in the combination of traditional products with modern treatments and future challenges in the field are also highlighted. Recent Advances: Natural compounds have been used in skin wound care for many years due to their therapeutic activities, including anti-inflammatory, antimicrobial, and cell-stimulating properties. The clinical efficacy of these compounds has been investigated through in vitro and in vivo trials using both animal models and humans. Besides the important progress regarding the development of novel extraction methods, purification procedures, quality control assessment, and treatment protocols, the exact mechanisms of action, side effects, and safety of these compounds need further research. Critical Issues: The repair of skin lesions is one of the most complex biological processes in humans, occurring throughout an orchestrated cascade of overlapping biochemical and cellular events.

    Traditional pottery manufacturing involves firing of the ceramics in kilns, a process that leads to high concentrations of airborne particles that are harmful to human health. In order to assess the associated exposure levels and the involved risks, here, for the first time, we investigate the size, the concentration and the elemental composition of the particles emitted during the different stages of the ceramic firing process. Number size distributions of the emitted particles, having diameters in the range from 10 nm to 20 μm, were measured in a traditional small-sized pottery studio using a Scanning Mobility Particle Sizer (SMPS) and an Optical Particle Counter (OPC). The measurements showed dominance of the nanoparticle mode (i.e., particles smaller than 100 nm) when the kiln reached temperatures above 600 °C. The mean size of the particles ranged from 30 to 70 nm and their peak number concentration was 6.5 × 10(5) cm(-3) during the first stage of the firing process where the ceramics were unpainted and unglazed. During the second stage of the firing process, where the ceramics were painted and glazed, the mean particle size ranged from 15 to 40 nm and their number concentration peaked at 1.2 × 10(6) cm(-3). Elemental analysis of individual particles collected during the two firing stages and studied by Energy-Dispersive X-ray (EDX) spectroscopy showed that the emitted nanoparticles contain significant amounts of lead. These findings provide new information for understanding the health impacts of traditional pottery manufacturing, and underline the need for adopting adequate measures to control nanoparticle emissions at the source.

    Background Over one hundred different pharmaceutical dosage forms have been recorded in literatures of Traditional Persian Medicine among which nasal forms are considerable. Objectives This study designed to derive the most often applied nasal dosage forms together with those brief clinical administrations. Materials and Methods In the current study remaining pharmaceutical manuscripts of Persia during 9th to 18th century AD have been studied and different dosage forms related to nasal application of herbal medicines and their therapeutic effects were derived. Results By searching through pharmaceutical manuscripts of medieval Persia, different nasal dosage forms involving eleven types related to three main groups are found. These types could be derived from powder, solution or liquid and gaseous forms. Gaseous form were classified into fumigation (Bakhoor), vapor bath (Enkebab), inhalation (Lakhlakheh), aroma agents (Ghalieh) and olfaction or smell (Shomoom). Nasal solutions were as drops (Ghatoor), nasal snuffing drops (Saoot) and liquid snuff formulations (Noshoogh). Powders were as nasal insufflation or snorting agents (Nofookh) and errhine or sternutator medicine (Otoos). Nasal forms were not applied only for local purposes. Rather systemic disorders and specially CNS complications were said to be a target for these dosage forms. Discussion While this novel type of drug delivery is known as a suitable substitute for oral and parenteral administration, it was well accepted and extensively mentioned in Persian medical and pharmaceutical manuscripts and other traditional systems of medicine as well. Accordingly, medieval pharmaceutical standpoints on nasal dosage forms could still be an interesting subject of study. Therefore, the current work can briefly show the pharmaceutical knowledge on nasal formulations in medieval Persia and clarify a part of history of traditional Persian pharmacy. PMID:24624204

    Parkinson's disease has existed in different parts of the world since ancient times. The first clear description is found in the ancient Indian medical system of Ayurveda under the name Kampavata. Traditional therapies in the form of herbal preparations containing anticholinergics, levodopa, and monoamine oxidase inhibitors were used in the treatment of PD in India, China, and the Amazon basin. Scientific reevaluation of these therapies may be valuable, as shown in the case of Mucuna pruriens and Banisteria caapi. Complementary therapies such as massage therapy, biofeedback, and acupuncture may have beneficial effects for patients and deserve further study.

    The history of education and legislation of traditional Chinese medicine (TCM) and acupuncture in Canada is short. The first school of TCM opened its door to the general public in Canada in 1985 and the first legislation of acupuncture was introduced in Alberta, Canada in 1988. Currently, TCM and/or acupuncture have been regulated in five provinces in Canada. The legislation and regulation, as well as education of TCM and acupuncture vary among the five provinces in Canada. Opportunities and challenges facing TCM education exist simultaneously. Strategies are proposed to develop an international standard for TCM education in Canada, and possibly in other English speaking countries as well.

    One of the most promising and vibrant research areas in nanotechnology has been the field of metasurfaces. These are two dimensional representations of metaatoms, or artificial interfaces designed to possess specialized electromagnetic properties which do not occur in nature, for specific applications. In this article, we present a brief review of metasurfaces from a materials perspective, and examine how the choice of different materials impact functionalities ranging from operating bandwidth to efficiencies. We place particular emphasis on emerging and non-traditional materials for metasurfaces such as high index dielectrics, topological insulators and digital metamaterials, and the potentially transformative role they could play in shaping further advances in the field.

    Senile dementia is a syndrome in the elderly involving deficits in memory and cognition. There has been a long history of research and medical practice in dementia in China, during which the ancient Chinese people have formed a whole theory and accumulated abundant experience in the treatment of dementia. During recent decades, with new theories and technologies being digested and integrated, progress has been made in the medical and pharmacy research on senile dementia in China. In this review, we will focus on the traditional opinion, clinical practice, and recent progress in pharmacological research in China towards the treatment of dementia. We also discuss the potential trends of global convergence. PMID:18044136

    Factors that are important to successful face recognition, such as features, configuration, and pigmentation/reflectance, are all subject to change when a face has been engraved with ink markings. Here we show that the application of facial tattoos, in the form of spiral patterns (typically associated with the Maori tradition of a Moko), disrupts face recognition to a similar extent as face inversion, with recognition accuracy little better than chance performance (2AFC). These results indicate that facial tattoos can severely disrupt our ability to recognise a face that previously did not have the pattern.

    Recent advances in animal tracking and telemetry technology have allowed the collection of location data at an ever-increasing rate and accuracy, and these advances have been accompanied by the development of new methods of data analysis for portraying space use, home ranges and utilization distributions. New statistical approaches include data-intensive techniques such as kriging and nonlinear generalized regression models for habitat use. In addition, mechanistic home-range models, derived from models of animal movement behaviour, promise to offer new insights into how home ranges emerge as the result of specific patterns of movements by individuals in response to their environment. Traditional methods such as kernel density estimators are likely to remain popular because of their ease of use. Large datasets make it possible to apply these methods over relatively short periods of time such as weeks or months, and these estimates may be analysed using mixed effects models, offering another approach to studying temporal variation in space-use patterns. Although new technologies open new avenues in ecological research, our knowledge of why animals use space in the ways we observe will only advance by researchers using these new technologies and asking new and innovative questions about the empirical patterns they observe.

    The recent commissioning of the continuous 45T hybrid magnet at NHMFL has opened new horizon for science but carried with it new challenges that forced NMR spectroscopists to reevaluate the traditional approach to NMR instrumentation. Very recently, a world record frequency at 1.5GHz has been achieved, signaling the new era of NMR probe designs that may someday blur the distinction between the classic NMR and millimeter-wave spectroscopies. No longer can we ignore stray capacitances and exposed leads in the terrain where every millimeter of cable counts. The challenge brought about by ever increasing fields and consequently, frequency, requirements has stimulated ingenuity among scientists. This is eased by accelerated growth in RF communications and computing technologies that made available advanced devices with more speed, power, bandwidth, noise immunity, flexibility, and complexity in small space at very low costs. Utilization of these devices have been paramount consideration in cutting-edge designs at NHMFL for Condensed Matter NMR and will be described in this talk. I will also discuss a number of first >33T NMR experiments to date utilizing the strength of the field to expose, as well as to induce occurrence of, new physical phenomena in condensed matter and which resulted in better understanding of the physics of materials. This work has been a result of continuing collaboration with P. L Kuhns, W. G. Moulton, W. P. Halperin (NU), and W. G. Clark (UCLA).

    International guidelines on leg ulcers recommend measuring the ankle arm index (AAI) to diagnose and assess peripheral arterial occlusive disease (PAOD) of the lower limbs. These guidelines do not, however, describe the method which should be used to make the measurement: which artery should be measured -in the event of an open leg ulcer, what are the practical difficulties for positioning the cuff- how well do patients tolerate the procedure? We conducted a prospective study focusing on ease of use, tolerance and performance of AAI measurements in patients with leg ulcers. In compliance with recent French guidelines, we measured the AAI for both distal leg arteries and retained the lowest value for analysis. Within a six-month study period, 100 consecutive inpatients with leg ulcers of various etiologies were studied. Mean age was 75, female predominance 60%, body mass index 27. Etiologies of leg ulcers were pure venous (29%), mixed venous predominant (17%), pure arterial (9%), mixed arterial predominant (8%), mixed (6%), hypertensive ulcers (11%), rare cause (8%), multifactorial (12%). Pain was present in 92%, with a VAS above 3 for 73%. Measurement of AAI was possible in 98% of patients. It was too painful and thus considered unethical for two patients with hypertensive ulcers. For the 98 patients measured, the ulcer had to be protected during the measurement in 76%. The measurement procedure only took five minutes for one leg, and was judged easy to perform by 93% of the operators. For the majority (76%) of patients, the measurement was not painful. We determined the diagnostic performance of AAI by comparing the results with those of arterial ultrasound in 90 patients who had a complete arterial ultrasound exploration of the legs. Compared with arterial ultrasound, the sensitivity of AAI<0.9 for detecting the presence of PAOD was 84.7%, with 97% specificity. PAOD was not diagnosed in any patient who had two palpable distal pulses and a normal AAI. Measurement

    As the emphasis in cattle breeding is shifting from traits that increase income toward traits that reduce costs, national breeding indices are expanding to include functional traits such as calving ease (CE). However, one issue is the lack of knowledge of genetic relationships between CE and other dairy traits. The same can be said about gestation length (GL), a potential novel selection trait with considerable heritabilities and possible genetic relationships with the calving process. This study aimed to estimate the genetic relationships between CE, GL, and other dairy traits of interest using a national data set of 31,053 primiparous cow performance records, as well as to separate direct and maternal genetic effects. Chosen dairy traits included fertility (calving interval, days to first service, nonreturn rate after 56 d, number of inseminations per conception), milk production (milk yield at d 110 in milk, accumulated 305-d milk yield, accumulated 305-d fat yield, accumulated 305-d protein yield), type (udder depth, chest width, rump width, rump angle, mammary composition, stature, body depth), and lifespan traits (functional days of productive life). To allow the separation of direct and maternal genetic effects, a random sire of the calf effect was included in the multi-trait linear trivariate sire models fitted using ASReml. Significant results showed that easily born individuals were genetically prone to high milk yield and reduced fertility in first lactation. Difficult calving primiparous cows were likely associated with being high-producing, wide and deep animals, with a reduced ability to subsequently conceive. Individuals that were born relatively early were associated with good genetic merit for milk production. Finally, individuals carrying their offspring longer were genetically associated with being wide and large animals that were themselves born relatively early. The study shows that it is feasible and valuable to separate direct and maternal

    The aim of this paper was to estimate the genetic relationships among calving ease (CE), calf survival (CS), and gestation length (GL) to assess the possibility of including this information in beef cattle breeding programs. A total of 35,395 field records were available for CE, 30,684 for GL, and 36,132 for CS from the Asturiana de los Valles beef cattle breed. The 3 traits were analyzed as traits of the calf fitting a multivariate linear mixed model. Estimates of heritability (+/-SE) for the direct genetic effects (CEd, GLd, and CSd) were 0.325 +/- 0.022, 0.331 +/- 0.026, and 0.226 +/- 0.018, respectively, whereas the estimates for maternal genetic effects (CEm, GLm, and CSm) were 0.066 +/- 0.018, 0.066 +/- 0.017, and 0.034 +/- 0.011. The estimates for the ratio of permanent environmental variance to phenotypic variance were CEc 0.090 +/- 0.011, GLc 0.066 +/- 0.011, and CSc 0.024 +/- 0.007. Genetic correlations between direct, maternal genetic, or permanent environmental effects involving CE and GL were, in general, positive and moderate, whereas those involving CE and CS were high. All were significant except for the pair CEm-GLm (0.277 +/- 0.172). Correlations between GL and CS were nonsignificant. Genetic correlations for CEd-CEm, GLd-GLm, and CSd-CSm were negative and high, ranging from -0.461 +/- 0.120 for GLd-GLm to -0.821 +/- 0.145 for CSd-CSm. The genetic correlations for CEd-CSm and for CSd-CEm were negative, significant, and high, whereas that for GLd-CEm was moderate (-0.323 +/- 0.124) and that for GLd-CSm was nonsignificant. The genetic correlations for GLm with the direct effects of the other traits were non-significant. Strong selection for CE will result in a significant correlated response in CS. Therefore, CE can be considered an early indicator of CS performance. The benefit of using GL as a correlated trait in a genetic evaluation with CE and CS seems limited.

    2013-01-01

    Background Medications for respiratory disorders including asthma and chronic obstructive pulmonary disease (COPD) are typically delivered to the lung by means of a handheld inhaler. Patient preference for and ability to use the inhaler may influence their adherence to maintenance therapy, and adherence may affect treatment outcomes. In this study, patient experience of using a dry powder inhaler (DPI), the ELLIPTA™ DPI, in clinical trials of a new maintenance therapy for asthma and COPD was investigated. The ELLIPTA DPI has been designed to contain two separate blister strips from which inhalation powder can be delivered, and to be simple to use with a large, easy-to-read dose counter. Methods Semi-structured, in-depth, qualitative interviews were carried out 2–4 weeks after patients had completed one of six phase IIIa clinical trials using the ELLIPTA DPI. Interview participants were asked about their satisfaction with various attributes of the inhaler and their preference for the ELLIPTA DPI relative to currently-prescribed inhalers, and responses were explored using an inductive content analysis approach. Participants also rated the performance of the inhaler on several criteria, using a subjective 1–10 scale. Results Participants with asthma (n = 33) and COPD (n = 42) reported high levels of satisfaction with the ELLIPTA DPI. It was frequently described as straightforward to operate and easy to use by interview participants. Ergonomic design, mouthpiece fit, and dose counter visibility and ease of interpretation emerged as frequently cited drivers of preference for the ELLIPTA DPI compared with their current prescribed inhaler. Of participants with asthma, 71% preferred the ELLIPTA DPI to DISKUS™ and 60% to metered dose inhalers. Of participants with COPD, 86% preferred the ELLIPTA DPI to DISKUS, 95% to HandiHaler™, and 85% to metered dose inhalers. Overall average performance scores were >9 (out of 10) in participants with asthma and COPD

    Background Recent years have seen an increased amount of natural language processing (NLP) work on full text biomedical journal publications. Much of this work is done with Open Access journal articles. Such work assumes that Open Access articles are representative of biomedical publications in general and that methods developed for analysis of Open Access full text publications will generalize to the biomedical literature as a whole. If this assumption is wrong, the cost to the community will be large, including not just wasted resources, but also flawed science. This paper examines that assumption. Results We collected two sets of documents, one consisting only of Open Access publications and the other consisting only of traditional journal publications. We examined them for differences in surface linguistic structures that have obvious consequences for the ease or difficulty of natural language processing and for differences in semantic content as reflected in lexical items. Regarding surface linguistic structures, we examined the incidence of conjunctions, negation, passives, and pronominal anaphora, and found that the two collections did not differ. We also examined the distribution of sentence lengths and found that both collections were characterized by the same mode. Regarding lexical items, we found that the Kullback-Leibler divergence between the two collections was low, and was lower than the divergence between either collection and a reference corpus. Where small differences did exist, log likelihood analysis showed that they were primarily in the area of formatting and in specific named entities. Conclusion We did not find structural or semantic differences between the Open Access and traditional journal collections. PMID:19527520

    Background: During the last decades, there have been great advancements in the field of preventive medicine. Research has demonstrated that nutrition plays a crucial role in the prevention of chronic diseases. The concept of functional food was first introduced in Japan during the 1980s. It proposes to consider food not only vital to survive, but also a mean for mental and physical well-being, contributing to the prevention and reduction of risk factors for diseases. However, there is evidence that the concept was believed by ancient physicians as well. One of the traditional systems of medicines is traditional Persian medicine (TPM). Rhazes said; “as long as a disease could be treated with food, medicine should be avoided” Methods: We carried out a review of Avicenna’s Canon of medicine and Rhazes books for the definition of food and drug and similar concepts of functional food. We listed the identified concepts along with their examples. Results: The classification of food and their therapeutic use were explained in Canon of medicine. Rhazes has a book called ‘Manafe al-Aghziyeh’, in which he writes about the medicinal benefits of different nutrition. Five concepts (food, drug, medicinal food, nutritional medicine and antidote or poison) were noted in these books. Conclusion: There are many recommendations on food for the prevention and treatment of diseases in TPM books, which can be the basis for novel research studies. PMID:27516666

    Background: During the last decades, there have been great advancements in the field of preventive medicine. Research has demonstrated that nutrition plays a crucial role in the prevention of chronic diseases. The concept of functional food was first introduced in Japan during the 1980s. It proposes to consider food not only vital to survive, but also a mean for mental and physical well-being, contributing to the prevention and reduction of risk factors for diseases. However, there is evidence that the concept was believed by ancient physicians as well. One of the traditional systems of medicines is traditional Persian medicine (TPM). Rhazes said; “as long as a disease could be treated with food, medicine should be avoided” Methods: We carried out a review of Avicenna’s Canon of medicine and Rhazes books for the definition of food and drug and similar concepts of functional food. We listed the identified concepts along with their examples. Results: The classification of food and their therapeutic use were explained in Canon of medicine. Rhazes has a book called ‘Manafe al-Aghziyeh’, in which he writes about the medicinal benefits of different nutrition. Five concepts (food, drug, medicinal food, nutritional medicine and antidote or poison) were noted in these books. Conclusion: There are many recommendations on food for the prevention and treatment of diseases in TPM books, which can be the basis for novel research studies. PMID:27840499

    Achieving a sustainable use of water resources, in view of the increased food and biofuel demand and possible climate change, will require optimizing irrigation, a highly nontrivial task given the unpredictability of rainfall and the numerous soil-plant-atmosphere interactions. Here we theoretically analyze two different irrigation schemes, a traditional scheme, consisting of the application of fixed water volumes that bring soil moisture to field capacity, and a microirrigation scheme supplying water continuously in order to avoid plant water stress. These two idealized irrigation schemes are optimal in the sense that they avoid crop water stress while minimizing water losses by percolation and runoff. Furthermore, they cover the two extremes cases of continuous and fully concentrated irrigation. For both irrigation schemes, we obtain exact solutions of the steady state soil moisture probability density function with random timing and amounts of rainfall. We also give analytical expressions for irrigation frequency and volumes under different rainfall regimes, evaporative demands, and soil types. We quantify the excess volumes required by traditional irrigation, mostly lost in runoff and deep infiltration, as a function of climate, soil, and vegetation parameters.

    A two story modified ranch house in metropolitan Atlanta screen tested at 11 pCi/l. The house is built over a 3500 sq. ft. dirt crawl space and has had three sections added over the course of thirty years. Each addition added portions to the block foundation wall, resulting in a labyrinth of block walls and columns. There is also a wine cellar that was built out of a section of the crawl space. The wine-cellar has block walls and a brick tiled floor over a concrete slab. Access to the wine cellar is through a circular stair case which is entered from the living room/wet bar area of the house. Radon mitigation was accomplished using a combination of both a non-traditional crawl space ventilation/pressurization and a traditional subslab depressurization. The ventilation blower was equipped with a timer and an hour meter to allow the adjustment and optimization of ventilation rates. Crawl space temperature was regulated by limiting thermostats. The mitigation set-up afforded a unique opportunity to test a series of operator variable parameters including radon levels, temperatures, humidity levels, and ventilation/pressurization rates.

    India has been recognized all over the world for spices and medicinal plants. Both exhibit a wide range of physiological and pharmacological properties. Current biomedical efforts are focused on their scientific merits, to provide science-based evidence for the traditional uses and to develop either functional foods or nutraceuticals. The Indian traditional medical systems use turmeric for wound healing, rheumatic disorders, gastrointestinal symptoms, deworming, rhinitis and as a cosmetic. Studies in India have explored its anti-inflammatory, cholekinetic and anti-oxidant potentials with the recent investigations focusing on its preventive effect on precarcinogenic, anti-inflammatory and anti atherosclerotic effects in biological systems both under in vitro and in vivo conditions in animals and humans. Both turmeric and curcumin were found to increase detoxifying enzymes, prevent DNA damage, improve DNA repair, decrease mutations and tumour formation and exhibit antioxidative potential in animals. Limited clinical studies suggest that turmeric can significantly impact excretion of mutagens in urine in smokers and regress precancerous palatal lesions. It reduces DNA adducts and micronuclei in oral epithelial cells. It prevents formation of nitroso compounds both in vivo and in vitro. It delays induced cataract in diabetes and reduces hyperlipidemia in obese rats. Recently several molecular targets have been identified for therapeutic / preventive effects of turmeric. Fenugreek seeds, a rich source of soluble fiber used in Indian cuisine reduces blood glucose and lipids and can be used as a food adjuvant in diabetes. Similarly garlic, onions, and ginger have been found to modulate favourably the process of carcinogenesis.

    In recent years, gasoline and diesel fuel have accounted for about 80 percent of total transportation fuel and nearly all of the fuel used in on-road vehicles. Growing concerns about the environmental effects of fossil fuel use and the Nation`s high level of dependence on foreign oil are providing impetus for the development of replacements or alternatives for these traditional transportation fuels. (The Energy Policy Act of 1992 definitions of {open_quotes}replacement{close_quotes} and {open_quotes}alternative{close_quotes} fuels are presented in the following box.) The Alternative Motor Fuels Act of 1988, the Clean Air Act Amendments of 1990 (CAAA90) and the Energy Policy Act of 1992 (EPACT) are significant legislative forces behind the growth of replacement fuel use. Alternatives to Traditional Transportation Fuels 1993 provides the number of on-road alternative fueled vehicles in use in the United States, alternative and replacement fuel consumption, and information on greenhouse gas emissions resulting from the production, delivery, and use of replacement fuels for 1992, 1993, and 1995.

    Photon traditional Chinese medicine (PTCM), and inter- discipline of photonics and traditional Chinese medicine (TCM), studies TCM, such as the diagnostics, therapeutics, indistinct disease theory, rehabilitation, health care and so forth, by using photonics. IN this paper, we will give an introduction of PTCM and review its progress in the collective interaction of low intensity laser irradiation with biological systems, the propagation of low intensity laser irradiation through tissue, the biophotonics representation of acupoint, low intensity laser therapy, TCM laser hemotherapy, laser acupuncture. In this paper, the concept of biological unit was put forward for acupoint and cell membrane receptors to be considered as an identical particle model. The interaction of identical particles was studied by quantum chemistry, as well as the response of the system interacting with physical factors by the time quantum theory on radiation-matter interaction. It was shown that the identical particles from coherent states, the response rate of the super-change state is a linear function of N2 and N3 (N is the particle number), and the one of the sub-change state is zero. Its application led to the explanation of the contribution of biological unit number of acupoint to acupoint specificity and the contribution of cell membrane receptors to low in tensity laser irradiation. The comparative research of acupoint effect and cell function with biophoton emission showed that acupoint states and the membrane receptor state are related to body diseases.

    Context: In the Iranian traditional medicine, anbarnesa smoke derived from burning female donkey’s dung has long been used for treatment of inflammatory ulcers and infections of the middle and external ear with no significant side effects. The aim of this study was to introduce anbarnesa and discuss its therapeutic effects. Evidence Acquisition: We conducted a systematic search in PubMed, Medline, Google, and Google Scholar databases to find studies on anbarnesa. The keywords searched were as follows: “anbarnesa,” “traditional medicine,” “medicinal smoke,” “donkey,” “dung,” “antimicrobial,” “inflammation,” “infection,” and “cytotoxicity. Results: Literature review reveals that ANNAS (anbarnesa smoke) enhances wound healing, decreases scar formation, inhibits growth of cancer cells (Hela and KB) and has antimicrobial properties. Also, ANNAS combined with propylene glycol is nontoxic in 1/64, 1/128, and 1/256 dilutions. Conclusions: The constituents of anbarnesa smoke mainly possess antibacterial, anti-inflammatory, and growth inhibition effects on cancer cells. PMID:26756020

    Traditions and ceremonies don't just happen on their own--they require vision and effort. When honor guard services are required, it is too late to think about getting one organized. Advance preparation and training are necessary if a ceremonial unit is to accomplish its mission in a manner that brings credit to the organization. A wise EMS leader will scan the environment and seek out opportunities to develop the capabilities, nurture traditions and arrange ceremonies that will contribute to organizational morale and support the achievement of the organization's mission.

  13. Access and benefits sharing of genetic resources and associated traditional knowledge in northern Canada: understanding the legal environment and creating effective research agreements

    2013-01-01

    Background Research in northern Canada focused on Aboriginal peoples has historically benefited academia with little consideration for the people being researched or their traditional knowledge (TK). Although this attitude is changing, the complexity of TK makes it difficult to develop mechanisms to preserve and protect it. Protecting TK becomes even more important when outside groups become interested in using TK or materials with associated TK. In the latter category are genetic resources, which may have commercial value and are the focus of this article. Objective This article addresses access to and use of genetic resources and associated TK in the context of the historical power-imbalances in research relationships in Canadian north. Design Review. Results Research involving genetic resources and TK is becoming increasingly relevant in northern Canada. The legal framework related to genetic resources and the cultural shift of universities towards commercial goals in research influence the environment for negotiating research agreements. Current guidelines for research agreements do not offer appropriate guidelines to achieve mutual benefit, reflect unequal bargaining power or take the relationship between parties into account. Conclusions Relational contract theory may be a useful framework to address the social, cultural and legal hurdles inherent in creating research agreements. PMID:23986896

    Cnidaria, the sister group to Bilateria, is a highly diverse group of animals in terms of morphology, lifecycles, ecology, and development. How this diversity originated and evolved is not well understood because phylogenetic relationships among major cnidarian lineages are unclear, and recent studies present contrasting phylogenetic hypotheses. Here, we use transcriptome data from 15 newly-sequenced species in combination with 26 publicly available genomes and transcriptomes to assess phylogenetic relationships among major cnidarian lineages. Phylogenetic analyses using different partition schemes and models of molecular evolution, as well as topology tests for alternative phylogenetic relationships, support the monophyly of Medusozoa, Anthozoa, Octocorallia, Hydrozoa, and a clade consisting of Staurozoa, Cubozoa, and Scyphozoa. Support for the monophyly of Hexacorallia is weak due to the equivocal position of Ceriantharia. Taken together, these results further resolve deep cnidarian relationships, largely support traditional phylogenetic views on relationships, and provide a historical framework for studying the evolutionary processes involved in one of the most ancient animal radiations.

  16. Edward o. Wilson and the organicist tradition.

    Gibson, Abraham H

    2013-01-01

    Edward O. Wilson's recent decision to abandon kin selection theory has sent shockwaves throughout the biological sciences. Over the past two years, more than a hundred biologists have signed letters protesting his reversal. Making sense of Wilson's decision and the controversy it has spawned requires familiarity with the historical record. This entails not only examining the conditions under which kin selection theory first emerged, but also the organicist tradition against which it rebelled. In similar fashion, one must not only examine Wilson's long career, but also those thinkers who influenced him most, especially his intellectual grandfather, William Morton Wheeler (1865-1937). Wilson belongs to a long line of organicists, biologists whose research highlighted integration and coordination, many of whom struggled over the exact same biological riddles that have long defined Wilson's career. Drawing inspiration (and sometimes ideas) from these intellectual forebears, Wilson is confident that he has finally identified the origin of the social impulse.

    Whether traditional Chinese medicine (TCM) could be categorized as a kind of science or not has been a controversial issue over last century. Part of the confusion is caused by the indistinguishable usage of Chinese words "science" and "scientific" during discussion. According to western academic standards, TCM cannot be considered as pure or conventional science. However, in author's view, the foundation of a majority part of TCM practice is probably scientific, while many TCM theories remain unproved. In this article, medical theories and practices are classified based on scientific content into eight levels: medical science, scientific medicine, medical system, medical theory, medical opinion, medical belief, medical cultism, and medical fraud. Both Western medicine and TCM are positioned in this system accordingly. Currently, the scientific level of TCM is much lower than that of Western medicine, and more research is needed for its improvement.

    Advances in automation capability and reliability have changed the role of humans from operating and controlling processes to simply monitoring them for anomalies. However, humans are traditionally bad monitors of highly reliable systems over time. Thus, the human is assigned a task for which he is ill equipped. We believe that this has led to the dominance of human error in process control activities such as operating transportation systems (aircraft and trains), monitoring patient health in the medical industry, and controlling plant operations. Research has shown, though, that an automated monitor can assist humans in recognizing and dealing with failures. One possible solution to this predicament is to use a polar-star display that will show deviations from normal states based on parameters that are most indicative of mission health.

    It has been suggested that girls and women coming from a Muslim background in the Asian sub-continent are disadvantaged in the educational sphere. In this study two particular aspects of this suggested disadvantage are investigated. First, the importance of educating males rather than females and secondly, the issue of parental and husband's control over the rights of women to education and work. Twenty-six Muslim females living in a large Scottish town but of a Pakistani Punjabi background were interviewed in depth. The findings, that these women considered that it is as important to educate girls as it is to educate boys, and that they acquiesced in parental and husband's control over the rights of females to be educated and work, are discussed within a cross-cultural perspective. It is concluded that such issues cannot be isolated from traditional values about the importance of upholding family honour.

    Environmental education efforts are increasingly recognizing the value of traditional knowledge, or indigenous science, as a basis to teach the importance of stewardship. The National Oceanic and Atmospheric Administration (NOAA) Pacific Services Center incorporates Polynesian indigenous science into formal and informal education components of its environmental literacy program. By presenting indigenous science side by side with NOAA science, it becomes clear that the scientific results are the same, although the methods may differ. The platforms for these tools span a vast spectrum, utilizing media from 3-D visualizations to storytelling and lecture. Navigating the Pacific Islands is a Second Life project in which users navigate a virtual Polynesian voyaging canoe between two islands, one featuring native Hawaiian practices and the other where users learn about NOAA research and ships. In partnership with the University of Hawai‘i Waikiki Aquarium, the Nana I Ke Kai (Look to the Sea) series focuses on connecting culture and science during cross-discipline, publicly held discussions between cultural practitioners and research scientists. The Indigenous Science Video Series is a multi-use, animated collection of short films that showcase the efforts of NOAA fisheries management and ship navigation in combination with the accompanying Polynesian perspectives. Formal education resources and lesson plans for grades 3-5 focusing on marine science have also been developed and incorporate indigenous science practices as examples of conservation success. By merging traditional knowledge and stewardship practices with NOAA science in educational tools and resources, NOAA's Pacific Services Center is helping to build and increase environmental literacy through the development of educational tools and resources that are applicable to place-based understanding and approaches.

  1. Traditional beliefs part of people's lives.

    Many couples worldwide practice rituals, herbal approaches, and similar traditional approaches to regulate fertility, but many of them are ineffective at preventing pregnancy and some may even be harmful. Health providers who are familiar with cultural beliefs about fertility may use nonharmful practices (e.g., rituals or storytelling) to teach couples about the fertile period or modern contraception. In fact, providers gain credibility when they teach family planning in ways that include traditional beliefs. In Nigeria, fertility regulation methods were used before modern contraception was introduced. In both Nigeria and Niger, some customs prohibit premarital sexual intercourse. Others promote sexual abstinence for up to three years to promote proper birth spacing. Even though many beliefs do not prevent pregnancy and cause no harm, they can be used to assure women that they are in control of their own fertility. Such beliefs include avoiding the sun or moon at certain times or wearing charms (e.g., dead spiders, children's teeth, or leopard skin bracelets). Providers should discourage dangerous or counterproductive beliefs, however. For example, the Nigerian belief that intercourse during menstruation turns people into albinos (although it is not harmful) may encourage sex during the fertile period. Some harmful beliefs or practices include douching with hot water, salt, vinegar, lemon, or potassium after sex; eating arsenic or castor oil seeds; and drinking water used to wash dead bodies. A 28-bead necklace is being used to help women keep track of their menstrual cycle and know when the risk of pregnancy is greatest. 11 white beads designate the fertile period, with fluorescent beads indicating the peak days of ovulation. In Brazil, the third most popular family planning method is natural family planning (NFP), indicating a clear demand for NFP; yet many couples use NFP incorrectly. In the Philippines, lime juice is used to prevent bean pods from opening and

    1988-01-01

    Mali's branch of the International Planned Parenthood Federation has found a vehicle that effectively conveys the idea of family planning through the use of contraception, a method that blends the country's cultural heritage and modern technology. Despite becoming the first sub-Saharan francophone country to promote family planning, Mali only counted 1% of its population using a modern method of contraception. So with the aid of The Johns Hopkins University/Population COmmunication Services (JHU/PCS), the Association Malienne pour la Protection et la Promotion de la Famille (AMPPF) developed several programs to promote contraception, but none were more successful than the Koteba Project, which used Mali's traditional theater form to communicate the message. While comical, the Koteba generally deals with social issues -- it informs and entertains. This particular Koteba told the story of two government employees, one with two wives and many children, the other with one wife and few children. The first one sees nothing but family problems: fighting wives and delinquent children. The second one, who had used family planning, enjoys a peaceful home. Upon hearing of his friend's successes with family planning, the tormented government employee becomes convinced of its needs, and persuades his wives to accompany him to a family planning clinic. Developed at a cost of approximately US $3000 and televised nationwide, the Koteba proved effective. A survey of 500 people attending an AMPPF clinic revealed that 1/4 of them remembered the program. With the success of the Koteba, JHU/PCS and AMPPF are now exploring other traditional channels of communication.

    Food insecurity is a growing concern for indigenous communities worldwide. While the risk of heavy metal contamination associated to wild food consumption has been extensively studied in the Arctic, data are scarce for the Boreal zone. This study addressed the concerns over possible heavy metal exposure through consumption of traditional food in four Anishnaabeg communities living in the Eastern North American boreal forest. Liver and meat samples were obtained from 196 snowshoe hares (Lepus americanus) trapped during winter 2012 across the traditional lands of the participating communities and within 56-156km of a copper smelter. Interviews were conducted with 78 household heads to assess traditional food habits, focusing on snowshoe hare consumption. Concentrations in most meat and liver samples were below the detection limit for As, Co, Cr, Ni and Pb. Very few meat samples had detectable Cd and Hg concentrations, but liver samples had mean dry weight concentrations of 3.79mg/kg and 0.15mg/kg respectively. Distance and orientation from the smelter did not explain the variability between samples, but percent deciduous and mixed forest cover had a marginal negative effect on liver Cd, Cu and Zn concentrations. The estimated exposition risk from snowshoe hare consumption was low, although heavy consumers could slightly exceed recommended Hg doses. In accordance with the holistic perspective commonly adopted by indigenous people, the nutritional and sociocultural importance of traditional food must be considered in risk assessment. Traditional food plays a significant role in reducing and preventing serious health issues disproportionately affecting First Nations, such as obesity, diabetes, and cardiovascular diseases.

  9. Contemporary Inuit Traditional Beliefs Concerning Meteorites

    NASA Astrophysics Data System (ADS)

    1992-07-01

    Inuit religious mythology and the importance of meteorites as "messages" from the Creator of all things is only now being recognized. Field investigations near Resolute, Cornwallis Island in the high Canadian Arctic in 1988 are the bases for this paper. Through interpreters, several elders of the local Inuit described in detail the Inuit belief, recognition, and wonder at the falling meteors & meteorites during the long Polar Night and Polar Day. Such events are passed on in the oral tradition from generation to generation by the elders and especially those elders who fulfill the shamanistic roles. The Inuit have come across rocks that they immediately recognize as not being "natural" and in the cases of a fall that was observed and the rock recovered the meteorite is kept either on the person or in some hidden niche known only to that person. In one story recounted a meteorite fell and was recovered at the birth of one very old elder and the belief was that if the rock was somehow damaged or taken from his possession he would die. Some indirect indication also was conveyed that the discovery and possession of meteorites allow shaman to have "supernatural" power. This belief in the supernatural power of meteorites can be seen historically in many societies, including Islam and the "black rock" (Kaaba) of Mecca. It should also be noted, however, that metallic meteorites were clearly once the major source of iron for Eskimo society as is indicated from the recovery of meteoritical iron arrow heads and harpoon heads from excavated pre-Viking contact sites. The one evident thing that became clear to the author is that the Inuit distinctly believe that these meteorites are religious objects of the highest order and it brings into question the current academic practice of sending meteorites south to research institutes. Any seeming conflict with the traditional use of meteoric iron is more apparent than real--the animals, the hunt, and the act of survival--all being

    Traditional healing has always been a component of health care. In South Africa, traditional healers can obtain licences to practise but very little groundwork has been done to integrate Westernized medicine with traditional healing. The actual contribution of traditional healers to health care in the province of Kwa-Zulu Natal or South Africa is not known. This study determined the role of traditional healers in Durban, Kwa-Zulu Natal, the number of patients who consulted traditional healers, the types of conditions treated and the frequency of consultations. The opinions about physiotherapy of the patients who frequently consult traditional healers were also explored. Data were collected from 30 traditional healers and their 300 patients by means of questionnaires and interviews. The results show 70% of the patients would consult traditional healers as a first choice. Sangomas were the most popular type of healers and had as many as 20 patients per day. A significantly large number of patients consulted traditional healers for potentially life-threatening conditions. The patients knew very little or nothing about physiotherapy. We conclude that traditional healing is an integral component of health care in South Africa. Health care professionals need to be proactive in integrating traditional healing with Westernized practices to promote health for all.

    Social work authors in the 1950s claimed progressivism as a unique social work "tradition" and set of values, and this historical interpretation has influenced many versions of social work history since that time. Today, other voices in the profession claim various divergent traditions for social work and note that the progressive tradition has…

    The centre of origin of the oil palm is the tropical rain forest region of West Africa. It is considered to be the 200-300 kilometre wide coastal belt between Liberia and Mayumbe. The oil palm tree has remained the 'tree of life' of Yoruba land as well as of other parts of southern West Africa to which it is indigenous. The Yoruba are adept at spinning philosophical and poetical proverbs around such ordinary things as hills, rivers, birds, animals and domestic tools. Hundreds of the traditional proverbs are still with us, and through them one can see the picture of the environment that contributed to the moulding of the thoughts of the people. Yoruba riddles or puzzles were also couched in terms of the environment and the solutions to them were also environmental items. They have a popular saying: A je eran je eran a kan egungun, a je egungun je egungun a tun kan eran: 'A piece of meat has an outer layer of flesh, an intermediate layer of bone and an inner layer of flesh'. What is it? A palm fruit: it has an outer edible layer, the mesocarp; then a layer of shell, inedible, and the kernel inside, edible. The solution to this puzzle summarises the botanical and cultural characteristics of the palm fruit.

    Fifteen human embedded third molars were used in this in vitro study to evaluate the effects of two bleaching products associated or not with Argon laser application. The samples received a cervical-apical cut and were longitudinally cut into 4 parts resulting in 75 specimens. These parts were divided at random into 5 groups and submitted to the traditional power bleaching procedure for enamel. Group 1 was separated as a control group. Group 2 was exposed to 37 % carbamide peroxide bleaching solution and developed with an Argon laser application. The same solution was used in Group 3 but the bleaching was developed with an halogen lamp irradiation. 35 % carbamide peroxide were used in Groups 4 and 5. One was developed as Group 2 and the other as Group 3. The samples were analyzed under a photoreflectance experiment. We observed that Group 2 presented more white spectra than Group 3. However, Groups 4 and 5 showed the same results independent of the use of the laser or the halogen lamp for the light curing. Comparing both bleaching products, the 35 % carbamide peroxide was more efficient on its purposes than the other one.

  2. Antifertility effect of Jamu (traditional herbal medicine).

    Rahwana and Kursani, 2 brands of jamu, a traditional Malay herbal medicine, were investigated for antifertility properties in rats and mice. The findings suggest that jamu has an antifertility effect in both these rodents. This effect appears to be dose dependent and in addition the stage at which it was fed also appears to be crucial for the effect to manifest. Rahwana is effective when fed on day 4 of gestation. However jamu Kursani does not appear to be dose dependent and is effective when fed on days 1 and 4 of gestation. Jamu Rahwana does not alter the LH or estrogen levels in rats. Therefore, the induction of the antifertility effect is suggested to be by means other than hormonal. It is felt that jamu either inhibits the implantation of the zygote or causes resorption of the fetus. Whether any antifertility effect exists in women using jamu remain to be clarified. The mechanism of action, its reliability and effectiveness as a contraceptive, the side effects, if any, pharmacology of the active ingredient and other relevant investigations need to be carried out before it can be recommended for human use. The study does indicate that jamu has potential as an antifertility agent and could be effectively used in fertility regulation.

    Fifty-six ethanolic extracts of various parts of 39 plants used in traditional Australian Aboriginal medicine were investigated for their antibacterial activities against four Gram-positive (Bacillus cereus, Enterococcus faecalis, Staphylococcus aureus and Streptococcus pyogenes) and four Gram-negative (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa and Salmonella typhimurium) bacterial species. In a plate-hole diffusion assay, 12 extracts inhibited the growth of one or more of the bacteria, with five extracts showing broad spectrum antibacterial activity against Gram-positive bacteria. B. cereus was the most susceptible bacterium, with all 12 extracts displaying activity against this organism. Extracts from the leaves of Eremophila species (Myoporaceae) were the most active, with Eremophila duttonii exhibiting the greatest activity (against Gram-positive bacteria). The antibacterial effects of E. duttonii were further investigated by time-course growth assays which showed that significant growth inhibition was observed in cultures incubated in the presence of the extract within 1 h for B. cereus, E. faecalis and S. aureus and 2 h for S. pyogenes.

    Herbal medicine is the oldest form of healthcare known to humanity. Recently, much attention is being directed toward the use of antioxidants. There are some very commonly used Ayurvedic preparations that might have inbuilt antioxidant activity, and their therapeutic potential can be partially attributable to its antioxidant activity. Hence, it was proposed to find out antioxidant activity of such common formulations. Estimation of innate antioxidant activity of some commonly used traditional formulations. In this study, five formulations were evaluated for antioxidant activity in comparison to gallic acid (standard) using the in vitro reducing power method and superoxide radical scavenging activity by dimethyl sulfoxide method followed by calculation of scavenging activity and inhibitory concentration 50% (IC50). The result shows that Ayurvedic drug extracts possess good reducing power and antioxidant activity. Laxmivilas Ras shows higher reducing power ranging from 117 ± 0.021 to 0.176 ± 0.012 as compared to other extracts. The drug extracts were also found to be an efficient scavenger of superoxide radical. The IC50 values for Laxmivilas Ras, Agnitundi Vati, Ajmodadi Churna, Tribhuvankirti Rasa, gallic acid (standard) and Sitopladi Churna, were found to be 50.07, 98.41, 105.13, 116.39, 176.80, and 200.17, respectively. From this study, it can be concluded that the above Ayurvedic formulations possess antioxidant property. However, work could be initiated on the isolation and identification of these antioxidant components. PMID:28217554

    Cnidaria, the sister group to Bilateria, is a highly diverse group of animals in terms of morphology, lifecycles, ecology, and development. How this diversity originated and evolved is not well understood because phylogenetic relationships among major cnidarian lineages are unclear, and recent studies present contrasting phylogenetic hypotheses. Here, we use transcriptome data from 15 newly-sequenced species in combination with 26 publicly available genomes and transcriptomes to assess phylogenetic relationships among major cnidarian lineages. Phylogenetic analyses using different partition schemes and models of molecular evolution, as well as topology tests for alternative phylogenetic relationships, support the monophyly of Medusozoa, Anthozoa, Octocorallia, Hydrozoa, and a clade consisting of Staurozoa, Cubozoa, and Scyphozoa. Support for the monophyly of Hexacorallia is weak due to the equivocal position of Ceriantharia. Taken together, these results further resolve deep cnidarian relationships, largely support traditional phylogenetic views on relationships, and provide a historical framework for studying the evolutionary processes involved in one of the most ancient animal radiations.

  6. Beyond traditional pharmacology: new tools and approaches.

    PubMed

    Gurevich, E V; Gurevich, V V

    2015-07-01

    Traditional pharmacology is defined as the science that deals with drugs and their actions. While small molecule drugs have clear advantages, there are many cases where they have proved to be ineffective, prone to unacceptable side effects, or where due to a particular disease aetiology they cannot possibly be effective. A dominant feature of the small molecule drugs is their single mindedness: they provide either continuous inhibition or continuous activation of the target. Because of that, these drugs tend to engage compensatory mechanisms leading to drug tolerance, drug resistance or, in some cases, sensitization and consequent loss of therapeutic efficacy over time and/or unwanted side effects. Here we discuss new and emerging therapeutic tools and approaches that have potential for treating the majority of disorders for which small molecules are either failing or cannot be developed. These new tools include biologics, such as recombinant hormones and antibodies, as well as approaches involving gene transfer (gene therapy and genome editing) and the introduction of specially designed self-replicating cells. It is clear that no single method is going to be a 'silver bullet', but collectively, these novel approaches hold promise for curing practically every disorder.

    Metabolomics represent a global understanding of metabolite complement of integrated living systems and dynamic responses to the changes of both endogenous and exogenous factors and has many potential applications and advantages for the research of complex systems. As a systemic approach, metabolomics adopts a "top-down" strategy to reflect the function of organisms from the end products of the metabolic network and to understand metabolic changes of a complete system caused by interventions in a holistic context. This property agrees with the holistic thinking of Traditional Chinese Medicine (TCM), a complex medical science, suggesting that metabolomics has the potential to impact our understanding of the theory behind the evidence-based Chinese medicine. Consequently, the development of robust metabolomic platforms will greatly facilitate, for example, the understanding of the action mechanisms of TCM formulae and the analysis of Chinese herbal (CHM) and mineral medicine, acupuncture, and Chinese medicine syndromes. This review summarizes some of the applications of metabolomics in special TCM issues with an emphasis on metabolic biomarker discovery.

    Morality (from the Latin word moralitas that means "manner, character, proper behavior") is the differentiation of intentions, decisions, and actions between those that are good (or right) and those that are bad (or wrong). It is determined by how one's genetic makeup interacts with the environment. The development of morality has been a subject of investigation for a number of decades, and our understanding of neuro-biological and psychological mechanisms has increased manifolds in the last few decades. Development of morality has been of particular significance to psychiatric literature because of its significant contribution to the development of one's personality and it's aberration in various disorders. Cultures that have been just, equal and moral have been widely accepted and appreciated. In this review, we shall summarize the modern theories of moral development and then look into a part of our past and cultural heritage and review the traditional Hindu concepts of morality and their contribution to development of one's personality and their relevance in the current times.

    Fish represent the group of vertebrates with the largest number of species and the largest geographic distribution; they are also used in different ways by modern civilizations. The goal of this study was to compile the current knowledge on the use of ichthyofauna in zootherapeutic practices in Brazil, including ecological and conservational commentary on the species recorded. We recorded a total of 85 species (44 fresh-water species and 41 salt-water species) used for medicinal purposes in Brazil. The three most commonly cited species were Hoplias malabaricus, Hippocampus reidi, and Electrophorus electricus. In terms of conservation status, 65% of species are in the “not evaluated” category, and 14% are in the “insufficient data” category. Three species are in the “vulnerable” category: Atlantoraja cyclophora, Balistes vetula, and Hippocampus erectus. Currently, we cannot avoid considering human pressure on the population dynamics of these species, which is an essential variable for the conservation of the species and the ecosystems in which they live and for the perpetuation of traditional medical practices.

  11. Immobilization: A Revolution in Traditional Brewing

    NASA Astrophysics Data System (ADS)

    Virkajärvi, Ilkka; Linko, Matti

    In nature many micro-organisms tend to bind to solid surfaces. This tendency has long been utilized in a number of processes, for example in producing vinegar and acetic acid in bioreactors filled with wood shavings. Acetobacteria are attached to the surface of these shavings. In modern technical language: they are immobilized. Also yeast cells can be immobilized. In the brewing industry this has been the basis for maintaining efficient, continuous fermentation in bioreactors with very high yeast concentrations. The most dramatic change in brewing over recent years has been the replacement of traditional lagering of several weeks by a continuous process in which the residence time is only about 2h. Continuous primary fermentation is used on a commercial scale in New Zealand. In this process, instead of a carrier, yeast is retained in reactors by returning it partly after separation. In many pilot scale experiments the primary fermentation is shortened from about 1week to 1-2days using immobilized yeast reactors. When using certain genetically modified yeast strains no secondary fermentation is needed, and the total fermentation time in immobilized yeast reactors can therefore be shortened to only 2days.

    2009-04-01

    Kelvin interacted with many physicists and mathematicians with Irish connections, and these interactions are sketched. A number of suggestions of Irish or Irish-Scottish scientific traditions or networks are reviewed, but it is argued that the large number of interactions may be better explained just by the high quality of physics and mathematics in Ireland and Scotland in the nineteenth century. Kelvin's disapproval of science as carried out in Cambridge and London is discussed, and an attack by some of his followers on science at Oxford is also described. Finally a number of examples of Kelvin's most important work are outlined and some general features are pointed out; these include the willingness to tackle practical and engineering problems, and the ability to attempt to construct major syntheses, where appropriate taking note of religious themes, and drawing conclusions, positive or negative, on religious matters. These features are used to construct a highly tentative characterisation of a grouping of Irish and Scottish scientists centred largely round Kelvin.

    The work presented in this paper compares traditional Chinese medicine and traditional Thai medicine, expounding on origins, academic thinking, theoretical system, diagnostic method and modern development. Based on a secondary analysis of available literature, the paper concentrates on two crucial historical developments: (1) the response to, and consequences of, the impact of the Western medicine; and (2) the revival of traditional medicine in these two countries and its prospects. From a comparative perspective, the analysis has led to the conclusion that the rise and fall of traditional medicine is an issue closely related with social and political issues; and the development of traditional medicines requires national policy and financial support from governments, human resource development, the improvement of service quality, and the dissemination of traditional medicine knowledge to the public. In addition, this paper also suggests deepening exchanges and cooperation between China and Thailand, strengthening cooperation between traditional medicine and medical tourism.

  16. Slates from Uruguay: a traditional natural stone

    Slates were traditionally used as roofing material or for cladding worldwide and also in Uruguay. In regions where this resource was easily mined, the widespread application of slates in constructions resulted in the development of characteristic cultural landscapes. The application of slates in a wider sense is nowadays open for all uses of dimensional stone, compared to the restricted use as roofing or cladding material in the past. This has been achieved by the discovery and mining of new deposits within the last 25 years worldwide. Furthermore, the optimization of mining techniques that allows the excavation of larger blocks and the technical development for further handling of the blocks has contributed to an open spectrum of applications. The slate deposits from Uruguay are associated with the Neoproterozoic thrust and fold belt of the Dom Feliciano Belt. The slates are linked to calc-silicate strata in a greenschist facies volcano-sedimentary sequence and the deposits are located in the limb of a regional fold, where bedding and cleavage are parallel. The main lithotype is a layered and fine-grained calcareous phyllite with a quite diverse palette of colors: light green, grey, dark grey, reddish and black. The mined slate is split into slabs 0.5 - 2cm thick. The technical properties were investigated in a very systematic way with respect to the new European standards, showing values comparable to those registered for internationally known slates. In the past, the average production in Uruguay was around 4000 tons/year and a historical maximum of 13,000 tons was reached in 1993. The oscillations in the regional demand were the cause of several flourishing and decay cycles in the activity, but our investigation shows a considerable volume of indicated resources and therefore a very good potential. Exploration for colors and qualities and quantification of reserves is a prerequisite for the development of the sector.

    2015-01-01

    The Persian Traditional Medicine (PTM) system pays special attention to disease prevention. In PTM, physicians believe that overeating may cause accumulation of unhealthy substances in the body and diseases called “Emtela.” With respect to ocular health, foods can be categorized as beneficial and harmful. Harmful foods such as beef, geese, eggplant, cauliflower, and cheese can cause reduced vision. Dehydrating foods such as walnut and salty fish and hot foods such as garlic, onion, and pepper can cause dry eye. Food items that have beneficial effects on ocular health include thyme and saffron and fruits such as grape, fig, apple, plum, and berries. PTM stipulates that one should not drink water with meals or immediately afterwards, since drinking cold (icy) water causes difficulty in absorption of nutrients. Gulping water may have harmful effects on the eyes; therefore, PTM physicians recommend drinking water at a suitable temperature. It is not safe to drink water first at the morning. Sleeping right after eating is harmful too. Avicenna believes that sleeping on one’s belly after a full meal is very harmful for the eyes. Galen says that old people need deep and continuous sleep more than others. From the view of PTM, moving eyes in different directions, making delicate expressions, trying to look at delicate and find pictures and reading small letters would remove ocular fatigue. There have been mentions of local medicine for improving vision as well; for instance, fennel extracts, pomegranate juice, and honey which are suitable for vision improvement. Local administration of pomegranate blossoms is suitable for treating inflammatory reactions. PMID:27800504

    Chemical, physical, microbiological and sensory analyses were performed on 31 samples of Greek traditional sausages. The following attributes were recorded: fat 15.49-56.86%, moisture 21.92-65.40%, protein 14.73-26.74%, sodium chloride 2.36-4.13%, nitrites 0.0-3.26 ppm, mean nitrates 38.19 ppm, TBA value 0.42-5.33 mg malonaldehyde/kg, pH 4.74-6.74, water activity (a(w)) 0.88-0.97, firmness 0-64 Zwick units, lightness (L(*)) 25.03-35.37, redness (a(*)) 2.55-11.42, yellowness 4.42-12.96, aerobic plate count 5.48-9.32 cfu/g, lactic acid bacteria (LAB) 5.26-9.08 cfu/g, micrococci/staphylococci 4.11-6.91 cfu/g and Gram (-) bacteria 1.78-6.15 cfu/g. Mean sensory scores ranged from 3.14 to 3.54 on a 5-point hedonic scale. Two statistical analysis programmes (Praxitele and SPSS) were used for characterising and assessing the properties of sausages. The first two principal components (PC1-2) derived by SPSS (50.5% variance) describe more satisfactorily the variance than the corresponding PC1-2, PC1-3 obtained by Praxitele (40.4% variance). High consumer preference was strongly related to satisfactory appearance and strong taste, high LAB count, medium fat content, medium firmness and lightness (L(*)(surface)). Extreme attribute values (high or low) for firmness, moisture and fat content, low salt content and low taste were related to low consumer preference.

    Alternative exercise traditions (AETs) such as Pilates, yoga, Tai Chi Chuan, Qigong, and various forms of dance offer the potential to improve diverse outcomes among cancer survivors by reducing adverse symptoms and mood disorders, and by enhancing function. Additionally AETs have emerged as a potential means to address deficits in current disease-focused care delivery models which are marked by prevalent under-treatment of symptoms and physical impairments. Relative to therapeutic exercise in allopathic models, many AETs are comparatively affordable and accessible. AETs have the further potential to simultaneously address needs spanning multiple domains including social, physical, and psycho-emotional. AETs additionally offer the salient benefits of promoting integrated whole body movement and concurrently enhancing strength, coordination, balance, posture, flexibility, and kinesthetic awareness. Despite AETs' benefits, compelling concerns leave many clinicians ambivalent and reluctant to endorse or even discuss them. One issue is the extensive heterogeneity across and even within specific AETs. An additional concern is that the one-size-fits-many nature of AET group classes undermines an instructor's capacity to individualize dose, type, frequency, and intensity, which are cornerstones of effective therapeutic exercise. Inconsistencies in AET practitioner expertise and certification, as well as the extent of practitioner familiarity with vulnerabilities unique to cancer populations, may also be problematic. At this juncture, an extensive literature of inconsistent quality that spans diverse cancer populations frustrates efforts to precisely determine the effect size of any specific AET in improving a specific outcome; Although systematic reviews and meta-analyses have concluded that AETs have beneficial effects, they consistently identify a high risk of bias in a majority of trials related to a lack of blinding, poor allocation concealment, small sample sizes

    UK cancer survival has improved, leading to an increase in review patients and pressure on clinics. Use of the Internet for information exchange between patients and healthcare staff may provide a useful adjunct or alternative to traditional follow-up. This study aimed to develop and evaluate a website for use in follow-up cancer care in terms of usability, feasibility and acceptability. A website was developed and underwent iterative amendment following patient usability testing in focus groups. Patients on follow-up completed a Computer and Internet Usage Questionnaire. Internet users consented to a randomised crossover study to complete paper and online questionnaires, browse the website and participate in a website evaluation interview. Patient website use was tracked. Usability: Website changes were made following patient testing (n= 21). Patients would have liked a 'personalized' website with links to their clinical team, out with the scope of this study. Feasibility: The majority of participants (65%) had Internet access. Age remained a differentiating factor. Acceptability: Final evaluation (n= 103) was positive although many would like to maintain face-to-face hospital contact. User involvement in website design can ensure patient needs are met. A website model for follow-up will suit some patients but others will prefer clinical contact.

    Traditional Chinese Medicine (TCM) is popular around the world and encompasses many different practices with particular emphasis on herbal TCM. Using the PubMed database, a literature search was undertaken to assess the extent herbal TCM products exert rare hepatotoxicity. Analysis of reported cases revealed numerous specified herbal TCM products with potential hepatotoxicity. Among these were An Shu Ling, Bai Fang, Bai Xian Pi, Ban Tu Wan, Bo He, Bo Ye Qing Niu Dan, Bofu Tsu Sho San, Boh Gol Zhee, Cang Er Zi, Chai Hu, Chaso, Chi R Yun, Chuan Lian Zi, Ci Wu Jia, Da Chai Hu Tang, Da Huang, Du Huo, Gan Cao, Ge Gen, Ho Shou Wu, Hu Bohe You, Hu Zhang, Huang Qin, Huang Yao Zi, Hwang Geun Cho, Ji Gu Cao, Ji Ji, Ji Xue Cao, Jiguja, Jin Bu Huan, Jue Ming Zi, Kamishoyosan, Kudzu, Lei Gong Teng, Long Dan Xie Gan Tang, Lu Cha, Ma Huang, Mao Guo Tian Jie Cai, Onshido, Polygonum multiflorum, Qian Li Guang, Ren Shen, Sairei To, Shan Chi, Shen Min, Shi Can, Shi Liu Pi, Shou Wu Pian, Tian Hua Fen, White flood, Wu Bei Zi, Xi Shu, Xiao Chai Hu Tang, Yin Chen Hao, Zexie, Zhen Chu Cao, and various unclassified Chinese herbal mixtures. Causality was firmly established for a number of herbal TCM products by a positive reexposure test result, the liver specific scale of CIOMS (Council for International Organizations of Medical Sciences), or both. Otherwise, the quality of case data was mixed, especially regarding analysis of the herb ingredients because of adulteration with synthetic drugs, contamination with heavy metals, and misidentification. In addition, non-herbal TCM elements derived from Agaricus blazei, Agkistrodon, Antelope, Bombyx, Carp, Fish gallbladder, Phellinus, Scolopendra, Scorpio, and Zaocys are also known or potential hepatotoxins. For some patients, the clinical course was severe, with risks for acute liver failure, liver transplantation requirement, and lethality. In conclusion, the use of few herbal TCM products may rarely be associated with hepatotoxicity in some

  2. Psychopathy: traditional and clinical antisocial concepts.

    Sutker, P B

    1994-01-01

    Advances in our knowledge about the concept of psychopathy and the repeated occurrence of antisocial behaviors in the face of adversity and punishment have been limited by a complex interplay of conceptual and methodological issues that have not yet been addressed adequately by psychosocial scientists. Foremost among the problems facing clinicians and researchers interested in this topic is the lack of agreement on the meaning and labelling of the construct. Scholars have not reached consensus in describing a category within a diagnostic system that distinguishes a relatively homogeneous group of individuals sharing a set of characteristics, or a class of persons that can be identified reliably from those who exhibit other perhaps closely related behavioral abnormalities and so-called normal individuals. Disagreements about the construct in question have been sufficiently problematic that some researchers and clinicians have decided that the notion of psychopathy or APD, taken to represent a mental disorder, is simply a myth or a judgment label concocted to justify societal management of offensive and repugnant behaviors (cf., Blackburn, 1988; Lewis & Balla, 1975; Pilgrim, 1987). Scholars such as Holmes (1991) and Wulach (1983) have called for elimination of the category as a mental disorder diagnosis, because it offers an opportunity for making value assessments rather than clinically appropriate decisions. Few disorders described in our psychopathology nomenclature are associated with such markedly negative attributions as is psychopathy, whether defined in the American or British traditions. The logical underpinning of much work in the field equates psychopathy or APD with heinous forms of criminality, lifestyle criminality, and special cases of antisocial behavior. In keeping with tendencies for society to conceptualize psychopathy as extreme misbehavior and to decry its consequences is a paper by Wells (1988), which exemplifies the emotion-focused thought and

    Aims and Objectives: The objectives of this study were to analyze the different reasons why patients with fractures patronize traditional bone setters (TBS) and their impression of the outcome of the treatment by the TBS. Materials and Methods: A 24 month prospective observational study was conducted from February 2012 to January 2014. All the patients were recruited from the orthopedics outpatient clinic. The demographic data of each patient, the type of injury, presentation to hospital or not, reasons for leaving the hospital, reasons for patronage of the TBS and their impression of the outcome of TBS’ treatment, effect of educational background on patronage of TBS and reason for presenting to hospital for orthodox treatment. Data Analysis: Analysis was done with SPSS software Version 20. Results: A total 79 patients were recruited for the study and they had different reasons for patronizing TBS. These reasons include an external locus of decision making in 19 (24.1%) patients, and greater faith in TBS compared to orthodox medicine in 16 (20.3%). Twelve (15.2%) believed that TBS are more competent than orthodox medical practitioners while another group 11 (13.9%) considered the fees of TBS cheaper than those in the hospital. The delay in treatment in the hospital, forceful removal of patients from hospital against their will and nonsatisfaction with hospital treatment accounted for 5 (6.3%). Poor attitude of hospital staff, fear of amputation, and patients being unconscious during the injury accounted for 2 (2.5%). Their ages ranged from 17 to 83 years, with mean age of 36.8 ± 11.8 years. The male: female ratio was 1.5:1. Conclusions and Recommendations: With recent advancements in the practice of orthopedics and trauma, there is still a very high patronage of the TBS by most of our patients. This is largely due to the dependence of the patients on their sponsors for treatment, while the influence of cultural and religious beliefs continues to play a major

    With the development of the knowledge economy, knowledge has become one of the most important resources for social progress and economic development. Some countries have proposed measures for the protection of their own traditional knowledge. Traditional Chinese medicine belongs to the category of intangible cultural heritage because it is an important part of Chinese cultural heritage. Today the value of traditional knowledge of Chinese medicine has been widely recognized by the domestic and international public. This paper discusses the definition of traditional knowledge of Chinese medicine and its protection, and evaluates research on its classification. We review the present status of the protection of traditional knowledge of Chinese medicine and tentatively put forward some possible ideas and methods for the protection of traditional knowledge of Chinese medicine. Our goal is to find a way to strengthen the vitality of traditional Chinese medicine and consolidate its foundation. We believe that if we could establish a suitable sui generis(sui generis is a Latin term meaning "of its own kind" and is often used in discussions about protecting the rights of indigenous peoples. Here we use it to emphasize the fact that protection of traditional knowledge of Chinese medicine cannot be achieved through existing legal means of protection alone due to its unique characteristics) system for traditional knowledge, a more favorable environment for the preservation and development of traditional Chinese medicine will ultimately be created.

    In this manuscript we bring to focus student perceptions of salience (or lack of thereof) of emotions in the undergraduate conceptual physics course (in the teacher education program) and their relevance to teaching and learning. Our analysis of student responses to the Mindfulness in Education Heuristic constitutes a feedback loop affording the teacher reflection over his instructional practices. Hence, we ponder pedagogical tools employed by the class instructor (second author) that students identify as evoking emotional responses (both positive and negative). Furthermore, we highlight this teacher's dispositions and his value system (axiology) that appear to bring to balance his passion for science (understood in a traditional Western way as a canon-based epistemology) and his approach to teaching that is driven by compassion towards his students many of whom perceive physics as challenging. We argue that adopting mindful disposition affords engaging in practices that assist in regulating emotions and attention that mediate learning of canonical science content. Likewise, we maintain that the instructor and his mindfulness-driven practices become a model to be replicated in his students' future careers. In such context, mindfulness may be perceived as part of what is referred to as a hidden curriculum. It is our position, however, that the science classroom is a site where wellness-promoting practices (such as mindfulness) should receive an overt attention by becoming science content to be learned and practiced by all citizens throughout everyday life thus contributing to its improved quality. In recognizing that such position may be challenging to adopt by science educators, we present the way the second author has been grappling with reframing his thinking around teaching science. We encourage educators to utilize heuristic methodology towards reflecting on and informing their practice and as one way of exposing their students to social constructs such as

    This paper deals with the environmentally important issue regarding how best to motivate citizens to reduce their individual waste production. The paper discusses the pros and cons of the various financial incentives incorporated into the waste charging mechanism, pay-as-you-throw (PAYT). Pay-as-you-throw breaks with the tradition of paying for waste services through general blanket taxes or levies in the form of flat rates in that households are required to pay individually adjusted fees in the same way as water and electricity bills are calculated on an individual consumption basis. This difference is achieved through the interplay of three principal components which mark the technical implementation of PAYT: identification as a vehicle to attain accountability, measurement of the generated waste and/or corresponding services, and unit pricing as the basis for individual charges proportional to the extent of the obtained services. However, any motivating factor for inducing citizens to dispose of their recyclable discards and residual waste must be supported by a well developed collection infrastructure, good media information and an appropriate, transparent charging policy. Of particular importance is the use of a multi-tiered charge model, i.e., the charging of a fixed minimum fee plus certain variable components payable in respect of the service structure. The introduction of a basic charge, albeit reducing the intensity of the incentives created by the PAYT system, ensures that certain fixed costs for the provision of waste services will be covered independently from the actual waste developments and, at the same time, minimises the temptation to attempt to bypass the system. Such an arrangement for the waste charges neither contradicts the principle of pay-as-you-throw nor does it impair the waste diversion for which it is implemented. Waste statistics and figures representing the waste charging situation in Germany indicate that there is a relatively good

  7. Practice Location Characteristics of Non-Traditional Dental Practices.

    Current and future dental school graduates are increasingly likely to choose a non-traditional dental practice-a group practice managed by a dental service organization or a corporate practice with employed dentists-for their initial practice experience. In addition, the growth of non-traditional practices, which are located primarily in major urban areas, could accelerate the movement of dentists to those areas and contribute to geographic disparities in the distribution of dental services. To help the profession understand the implications of these developments, the aim of this study was to compare the location characteristics of non-traditional practices and traditional dental practices. After identifying non-traditional practices across the United States, the authors located those practices and traditional dental practices geographically by zip code. Non-traditional dental practices were found to represent about 3.1% of all dental practices, but they had a greater impact on the marketplace with almost twice the average number of staff and annual revenue. Virtually all non-traditional dental practices were located in zip codes that also had a traditional dental practice. Zip codes with non-traditional practices had significant differences from zip codes with only a traditional dental practice: the populations in areas with non-traditional practices had higher income levels and higher education and were slightly younger and proportionally more Hispanic; those practices also had a much higher likelihood of being located in a major metropolitan area. Dental educators and leaders need to understand the impact of these trends in the practice environment in order to both prepare graduates for practice and make decisions about planning for the workforce of the future.

    Modern buildings in Indonesia rely mostly on artificial lighting, heating, cooling and ventilation. It means more energy is used to drive mechanical appliances, and presumably not sustainable. Meanwhile modern buildings consume much energy, traditional architectures are known as the source of knowledge for sustainable, energy efficient and climate responsive design. Noticeably, one of the differences between modern and traditional buildings in Indonesia is shown in their strategy to provide thermal comfort to the user. Traditional buildings use natural ventilation, but modern buildings use mechanical air conditioning. By focusing on wind-driven ventilation, the study aims to investigate natural ventilation strategy of Indonesian traditional house, and their potential improvement to be used in modern Indonesian buildings. Three traditional houses are studied in this research, representing west, central, and east Indonesia. The houses are Lampung traditional house, Javanese traditional house, and Toraja traditional house. CFD simulation is conducted to simulate wind-driven ventilation behaviour and the temperature of the buildings. Concisely, the wind-natural ventilation of case study houses is potential to provide thermal comfort inside the houses. However, the strategy still can be optimized by adding some other passive design strategies: sun-shading; vegetation; or buildings arrangement in the traditional dwelling. Consideration about the roof’s shape and windows position to the roof is important as well to create a uniform air distribution.

    This paper presents what we have learned from the Ashtavaidya Ayurveda physicians of Kerala regarding the status of their unique medical tradition of Ayurveda in the contemporary context. We extensively interviewed several practicing Ashtavaidyas for the "Living History of Indian Scientific Traditions" archive, a new initiative at the NCBS, Bangalore to study the history of Indian sciences. As heirs of a tradition that has adapted and evolved over centuries without compromising its fundamental principles, their views on Ayurveda presented here represent an important contribution to the current debate on the role of traditional medicine in the Indian public health system.

    Beef stew and sponge cake were prepared utilising traditional recipes and recipes modified in accordance with NACNE, National Advisory Committee on Nutrition Education guidelines (1983). Triangle tests were performed to determine whether subjects could discriminate between samples prepared using the traditional recipes. Thirty subjects (15 men and 15 women) participated. No significant differences could be established between the traditional and modified stew or sponge cake in terms of eating quality. Modification of traditional recipes by reducing sugar, fat and salt and increasing the fibre content without affecting the overall sensory quality that the consumer expects is an ideal way of achieving recommended dietary goals.

  11. Conceptions of traditional cosmological ideas among literate and nonliterate Nigerians

    Ogunniyi, M. B.

    This paper examines the nature of selected traditional cosmological concepts among literate and nonliterate Nigerians. An analysis of the data reveals that the subjects, irrespective of their level of education, class, sex, age, religion, tribe, or locality, hold in varying degrees certain traditional as well as scientific concepts about the natural phenomena. An exposure of some of the subjects to an history/philosophy of science course appears to enhance their preference for a scientific worldview vis a vis a traditional point-of-view. The implications of these findings for traditional societies deserve a closer consideration.
