    This paper is dedicated to the research applicability of quality management problems of construction products. It is offered to expand quality management borders in construction, transferring its principles to urban systems as economic systems of higher level, which qualitative characteristics are substantially defined by quality of construction product. Buildings and structures form spatial-material basis of cities and the most important component of life sphere - urban environment. Authors justify the need for the assessment of urban environment quality as an important factor of social welfare and life quality in urban areas. The authors suggest definition of a term "urban environment". The methodology of quality assessment of urban environment is based on integrated approach which includes the system analysis of all factors and application of both quantitative methods of assessment (calculation of particular and integrated indicators) and qualitative methods (expert estimates and surveys). The authors propose the system of indicators, characterizing quality of the urban environment. This indicators fall into four classes. The authors show the methodology of their definition. The paper presents results of quality assessment of urban environment for several Siberian regions and comparative analysis of these results.

    Full Text Available Soil quality can be characterised by the harmony between it’s physical and biological state and the fertility. From the practical crop production viewpoint, some important contrasting factors of soil quality are: (1 soil looseness – compaction; (2 aggregation – clod and dust formation; friable structure – smeared or cracked structure; (3 organic material: conservation – decrease; (4 soil moisture: conservation – loss; water transmission – water-logging; (5 at least soil condition as a result of the long term effect of land use moderates or strengthens climatic harm. In our long-term research project practical soil quality factors were examined in arable field and experimental conditions. We state that prevention of the soil quality deterioration can be done by the developing and maintaining harmony between land use and environment. Elements of the soil quality conditions such as looseness, aggregation, workability, organic matter, water transport are examined and the improving methods are suggested. Tillage and production factors which can be adopted to alleviate the harmful climatic impacts are also summarised.

    2012-01-01

    Teaching is one of the most important factors affecting any education system. Many research efforts have been conducted to facilitate the presentation modes used by instructors in classrooms as well as provide means for students to review lectures through web browsers. Other studies have been made to provide acoustical design recommendations for classrooms like room size and reverberation times. However, using acoustical features of classrooms as a way to provide education systems with feedback about the learning process was not thoroughly investigated in any of these studies. We propose a system that extracts different sound features of students and instructors, and then uses machine learning techniques to evaluate the acoustical quality of any learning environment. We infer conclusions about the students' satisfaction with the quality of lectures. Using classifiers instead of surveys and other subjective ways of measures can facilitate and speed such experiments which enables us to perform them continuously...

    To evaluate the effectiveness of a leadership and management program in aged care. Double-blind cluster randomized controlled trial. Twelve residential and community-aged care sites in Australia. All care staff employed for 6 months or longer at the aged care sites were invited to participate in the surveys at 3 time points: baseline (time 1), 9 months from baseline (time 2), and 9 months after completion of time 2 (time 3) from 2011 to 2013. At each time point, at least 500 care staff completed a survey. At baseline (N = 503) the largest age group was 45 to 54 years (37%), and the majority of care staff were born in Australia (70%), spoke English (94%), and had at least completed secondary education (57%). A 12-month Clinical Leadership in Aged Care (CLiAC) program for middle managers, which aimed to further develop their leadership and management skills in creating positive workplace relationships and in enabling person-centered, evidence-based care. The primary outcomes were care staff ratings of the work environment, care quality and safety, and staff turnover rates. Secondary outcomes were care staff's intention to leave their employer and profession, workplace stress, job satisfaction, and cost-effectiveness of implementing the program. Absenteeism was excluded due to difficulty in obtaining reliable data. Managers' self-rated knowledge and skills in leadership and management are not included in this article, which focuses on care staff perceptions only. At 6 months after its completion, the CLiAC program was effective in improving care staff's perception of management support [mean difference 0.61, 95% confidence interval (CI) 0.04-1.18; P = .04]. Compared with the control sites, care staff at the intervention sites perceived their managers' leadership styles as more transformational (mean difference 0.30, 95% CI 0.09-0.51; P = .005), transactional (mean difference 0.22, 95% CI 0.05-0.39; P = .01), and less passive avoidant (mean difference 0.30, 95% CI 0

    Full Text Available Principal reasons of chemical pollution caused by the activity of filling stations, namely losses of hydrocarbon material, which takes place at transport operations and exploitation of imperfect equipment, have been analyzed. The primary sources of filling stations negative environmental impacts are shown to be storm waters, which wash off poured out petrochemicals from their territory, while direct environment pollution as a result of emergency overflows of petrochemicals is a rare phenomenon. It is indicated that the negative consequences of filling stations activity spread on atmospheric air, adjoining soils and water objects, including ground and underground water, and it is expressed in contamination of these environment components with petrochemicals and creation of threats for human health.

    2013-05-01

    This study analyses the processes through which the physical environment of health care settings impacts on patients' well-being. Specifically, we investigate the mediating role of perceptions of the physical and social environments, and if this process is moderated by patients' status, that is, if the objective physical environment impacts inpatients' and outpatients' satisfaction by different social-psychological processes. Patients (N=206) evaluated the physical and social environments of the care unit where they were receiving treatment, and its objective physical conditions were independently evaluated by two architects. Results showed that the objective environmental quality affects satisfaction through perceptions of environmental quality, and that patients' status moderates this relationship. For inpatients, it is the perception of quality of the social environment that mediates the relationship between objective environmental quality and satisfaction, whereas for outpatients it is the perception of quality of the physical environment. This moderated mediation is discussed in terms of differences on patients' experiences of health care environments.

    2011-10-01

    This concurrent mixed-method study examines the nurse work environment of high-quality Medicare-certified home health agencies. High-quality (n=6) and low-quality (n=6) home health agencies were recruited using agency-level publicly reported patient outcomes. Direct care registered nurses (RNs) from each agency participated in a focus group and completed the Practice Environment Scale of the Nurse Work Index (PES-NWI). No significant differences were found in the PES-NWI results between nurses working in high- and low-quality agencies, though nurses in high-quality agencies scored higher on all subscales. Nurses working in all the high-quality agencies identified themes of adequate staffing, supportive managers, and team work. These themes were not consistently identified in low-quality agencies. Themes of supportive managers and team work are reflective of effective leadership at the manager level. Agencies struggling to improve quality of care might consider developing their managers' leadership skills.

    2011-06-01

    Full Text Available Quality as a new requirement for the field of higher education leads institutions to seek to satisfy generic or specific quality standards imposed directly or indirectly by its customers. The aim of this study is to compare between ISO9001, as a generic quality standard, and the Code of Practice of the Quality Assurance Agency for Higher Education (QAA, as a specific quality standard. A correlation matrix is drawn and correlation rates are calculated to show similarities and differences between them. This paper shows, first, that ISO9001 and QAA Code of Practice are compatible. Second, implementing a quality management system in accordance with ISO9001 requirements can constitute an adequate framework for the application of the QAA Code of Practice requirements. Third, to make the ISO9001 requirements closer to a specific quality standard in the field of higher education, it is recommended to complete these standards by specific requirements to the field of higher education.

    2016-12-01

    Full Text Available There have been few empirical investigations of how individual differences influence the perception of the sonic environment. The present study included the Big Five traits and noise sensitivity as personality factors in two listening experiments (n = 43, n = 45. Recordings of urban and restaurant soundscapes that had been selected based on their type were rated for Pleasantness and Eventfulness using the Swedish Soundscape Quality Protocol. Multivariate multiple regression analysis showed that ratings depended on the type and loudness of both kinds of sonic environments and that the personality factors made a small yet significant contribution. Univariate models explained 48% (cross-validated adjusted R2 of the variation in Pleasantness ratings of urban soundscapes, and 35% of Eventfulness. For restaurant soundscapes the percentages explained were 22% and 21%, respectively. Emotional stability and noise sensitivity were notable predictors whose contribution to explaining the variation in quality ratings was between one-tenth and nearly half of the soundscape indicators, as measured by squared semipartial correlation. Further analysis revealed that 36% of noise sensitivity could be predicted by broad personality dimensions, replicating previous research. Our study lends empirical support to the hypothesis that personality traits have a significant though comparatively small influence on the perceived quality of sonic environments.

    2010-10-01

    Full Text Available Transaction costs are the costs to protect property rights. Institutions are shaped in order to control transaction costs in society. Studies have been developed to measure transaction costs both at the macro and microeconomic levels. Entry costs, i.e., the cost to start up a new business are considered a proxy for business environment quality, being also interpreted as a proxy to transaction cost measurement. This paper presents new elements in order to amplify the potential of research in business environment, particularly business entry costs. It stresses the limitation related to two theoretical points: first, the near decomposability of one complex transaction, and second, the complementarity between ex-ante and ex-post transaction costs, both related to the methodology adopted to measure business entrance costs.

    Predicting variations in the near-Earth space environment that can lead to spacecraft damage and failure, i.e. "space weather", remains a big space physics challenge. A recently funded project through the Los Alamos National Laboratory (LANL) Directed Research and Development (LDRD) program aims at developing a new capability to understand, model, and predict Space Hazards Induced near Earth by Large Dynamic Storms, the SHIELDS framework. The project goals are to understand the dynamics of the surface charging environment (SCE), the hot (keV) electrons representing the source and seed populations for the radiation belts, on both macro- and microscale. Important physics questions related to rapid particle injection and acceleration associated with magnetospheric storms and substorms as well as plasma waves are investigated. These challenging problems are addressed using a team of world-class experts in the fields of space science and computational plasma physics, and state-of-the-art models and computational facilities. In addition to physics-based models (like RAM-SCB, BATS-R-US, and iPIC3D), new data assimilation techniques employing data from LANL instruments on the Van Allen Probes and geosynchronous satellites are developed. Simulations with the SHIELDS framework of the near-Earth space environment where operational satellites reside are presented. Further model development and the organization of a "Spacecraft Charging Environment Challenge" by the SHIELDS project at LANL in collaboration with the NSF Geospace Environment Modeling (GEM) Workshop and the multi-agency Community Coordinated Modeling Center (CCMC) to assess the accuracy of SCE predictions are discussed.

  13. Water quality of hydrologic bench marks; an indicator of water quality in the natural environment

    Biesecker, James E.; Leifeste, Donald K.

    1974-01-01

    Water-quality data, collected at 57 hydrologic bench-mark stations in 37 States, allow the definition of water quality in the 'natural' environment and the comparison of 'natural' water quality with water quality of major streams draining similar water-resources regions. Results indicate that water quality in the 'natural' environment is generally very good. Streams draining hydrologic bench-mark basins generally contain low concentrations of dissolved constituents. Water collected at the hydrologic bench-mark stations was analyzed for the following minor metals: arsenic, barium, cadmium, hexavalent chromium, cobalt, copper, lead, mercury, selenium, silver, and zinc. Of 642 analyses, about 65 percent of the observed concentrations were zero. Only three samples contained metals in excess of U.S. Public Health Service recommended drinking-water standards--two selenium concentrations and one cadmium concentration. A total of 213 samples were analyzed for 11 pesticidal compounds. Widespread but very low-level occurrence of pesticide residues in the 'natural' environment was found--about 30 percent of all samples contained low-level concentrations of pesticidal compounds. The DDT family of pesticides occurred most commonly, accounting for 75 percent of the detected occurrences. The highest observed concentration of DDT was 0.06 microgram per litre, well below the recommended maximum permissible in drinking water. Nitrate concentrations in the 'natural' environment generally varied from 0.2 to 0.5 milligram per litre. The average concentration of nitrate in many major streams is as much as 10 times greater. The relationship between dissolved-solids concentration and discharge per unit area in the 'natural' environment for the various physical divisions in the United States has been shown to be an applicable tool for approximating 'natural' water quality. The relationship between dissolved-solids concentration and discharge per unit area is applicable in all the physical

Through investigation, we found that A. membranaceus var. mongholicus are cultivated in Hengshan mountain of Shanxi province, Longnan of Gansu province, south of Inner Mongolia and Qinghai provinces. A. membranaceus var. mongholicus is almost planted on the plain, except in Shanxi province it grows on the sunny side of the mountain. What is more, soil type, elevation, annual temperature and annual rainfall of these locations are different. So the ecological environments of cultivated location of Astragali Radix are different from each other. A. membranaceus is wild in Heilongjiang and northeast of Inner Mongolia, but the resource is drying up. It is also planted in few places of the provinces of Shanxi, Shandong, Hebei, Gansu, but cultivated scope of A. membranaceus is smaller than A. membranaceus var. mongholicus.. So A. membranaceus var. mongholicus possesses large part of Astragali Radix market. In market, there exists no unified specification fro slices of Astragali Radix, and specification of prepared slices will influence the contents of chemical components. Through investigation, different kind of prepared slices can be collected and compared, this provides evidences for quality control of prepared slices. Through investigation, five different specifications of prepared slices were found in market. The distributions of some specification of prepared slices are specified, like transverseprepared slices prepared from A. membranaceus only found in Heilongjiang province. Transverse prepared slices possess half part of prepared slice market, and can be used to identify original plant of Astragali Radix. So transverse prepared slices

    One of the biggest mysteries in cancer research remains why mutations in certain genes cause cancer only at specific sites in the human body. The poor correlation between the expression level of a cancer gene and the tissues in which it causes malignant transformations raises the question of which factors determine the tissue-specific effects of a mutation. Here, we explore why some cancer genes are associated only with few different cancer types (i.e., are specific), while others are found mutated in a large number of different types of cancer (i.e., are general). We do so by contrasting cellular functions of specific-cancer genes with those of general ones to identify properties that determine where in the body a gene mutation is causing malignant transformations. We identified different groups of cancer genes that did not behave as expected (i.e., DNA repair genes being tissue specific, immune response genes showing a bimodal specificity function or strong association of generally expressed genes to particular cancers). Analysis of these three groups demonstrates the importance of environmental impact for understanding why certain cancer genes are only involved in the development of some cancer types but are rarely found mutated in other types of cancer.

    While there is considerable evidence on the impact of specific design features on problems associated with dementia, the link between the quality of the built environment and quality of life of people with dementia is largely unexplored. This study explored the environmental and personal characteristics that are associated with quality of life in people with dementia living in residential aged care. Data were obtained from 275 residents of 35 aged care homes and analysed using linear regression. The quality of the built environment was significantly associated with the quality of life of the resident measured by global self-report. Environmental ratings were not associated with proxy or detailed self-report ratings. Higher quality of life is associated with buildings that facilitate engagement with a variety of activities both inside and outside, are familiar, provide a variety of private and community spaces and the amenities and opportunities to take part in domestic activities.

    The only property of reinforcement insects are commonly thought to learn about is its value. We show that larval Drosophila not only remember the value of reinforcement (How much?), but also its quality (What?). This is demonstrated both within the appetitive domain by using sugar vs amino acid as different reward qualities, and within the aversive domain by using bitter vs high-concentration salt as different qualities of punishment. From the available literature, such nuanced memories for the quality of reinforcement are unexpected and pose a challenge to present models of how insect memory is organized. Given that animals as simple as larval Drosophila, endowed with but 10,000 neurons, operate with both reinforcement value and quality, we suggest that both are fundamental aspects of mnemonic processing-in any brain.

    To investigate whether hospital characteristics not readily susceptible to change (i.e. hospital size, university status, and geographic location) are associated with specific self-reported nurse outcomes. Research often focuses on factors within hospitals (e.g. work environment), which are susceptible to change, rather than on structural factors in their own right. However, numerous assumptions exist about the role of structural factors that may lead to a sense of pessimism and undermine efforts at constructive change. Data was derived from survey questions on assessments of work environment and satisfaction, intention to leave, quality of care and burnout (measured by the Maslach Burnout Inventory), from a population-based sample of 11 000 registered nurses in Sweden. Mixed model regressions were used for analysis. Registered nurses in small hospitals were slightly more likely to rank their working environment and quality of nursing care better than others. For example 23% of staff in small hospitals were very satisfied with the work environment compared with 20% in medium-sized hospitals and 21% in large hospitals. Registered nurses in urban areas, who intended to leave their job, were more likely to seek work in another hospital (38% vs. 32%). While some structural factors were related to nurse-reported outcomes in this large sample, the associations were small or of questionable importance. The influence of structural factors such as hospital size on nurse-reported outcomes is small and unlikely to negate efforts to improve work environment. © 2013 John Wiley & Sons Ltd.

    2012-07-01

    In 2010, the United States Dept. of Energy initiated a research and development effort to develop modern modeling and simulation methods that could utilize high performance computing capabilities to address issues important to nuclear power plant operation, safety and sustainability. To respond to this need, a consortium of national laboratories, academic institutions and industry partners (the Consortium for Advanced Simulation of Light Water Reactors - CASL) was formed to develop an integrated Virtual Environment for Reactor Applications (VERA) modeling and simulation capability. A critical element for the success of the CASL research and development effort was the development of an integrated set of overarching requirements that provides guidance in the planning, development, and management of the VERA modeling and simulation software. These requirements also provide a mechanism from which the needs of a broad array of external CASL stakeholders (e.g. reactor / fuel vendors, plant owner / operators, regulatory personnel, etc.) can be identified and integrated into the VERA development plans. This paper presents an overview of the initial set of requirements contained within the VERA Requirements Document (VRD) that currently is being used to govern development of the VERA software within the CASL program. The complex interdisciplinary nature of these requirements together with a multi-physics coupling approach to realize a core simulator capability pose a challenge to how the VRD should be derived and subsequently revised to accommodate the needs of different stakeholders. Thus, the VRD is viewed as an evolving document that will be updated periodically to reflect the changing needs of identified CASL stakeholders and lessons learned during the progress of the CASL modeling and simulation program.

    2017-07-01

    We explored the concept of design quality in relation to healthcare environments. In addition, we present a taxonomy that illustrates the wide range of terms used in connection with design quality in healthcare. High-quality physical environments can promote health and well-being. Developments in healthcare technology and methodology put high demands on the design quality of care environments, coupled with increasing expectations and demands from patients and staff that care environments be person centered, welcoming, and accessible while also supporting privacy and security. In addition, there are demands that decisions about the design of healthcare architecture be based on the best available information from credible research and the evaluation of existing building projects. The basic principles of Arksey and O'Malley's model of scoping review design were used. Data were derived from literature searches in scientific databases. A total of 18 articles and books were found that referred to design quality in a healthcare context. Design quality of physical healthcare environments involves three different themes: (i) environmental sustainability and ecological values, (ii) social and cultural interactions and values, and (iii) resilience of the engineering and building construction. Design quality was clarified herein with a definition. Awareness of what is considered design quality in relation to healthcare architecture could help to design healthcare environments based on evidence. To operationalize the concept, its definition must be clear and explicit and able to meet the complex needs of the stakeholders in a healthcare context, including patients, staff, and significant others.

    Preschoolers' vocabulary acquisition sets the stage for later reading ability and school achievement. This study examined the role of socioeconomic status (SES) and the quality of the home environment of seventy-seven Chilean majority and Mapuche minority families from low and lower-middle-class backgrounds in explaining individual differences in vocabulary acquisition of their three-and-a-half-year-old children. Additionally, we investigated whether the relation between SES and receptive and expressive vocabulary was mediated by the quality of the home environment as the Family Investment Model suggests. The quality of the home environment significantly predicted receptive and expressive vocabulary above and beyond ethnicity, SES, parental caregiver status, and quantity of daycare. Furthermore, the quality of the home environment mediated the relation between SES and expressive and receptive vocabulary acquisition.

    2013-12-01

    Full Text Available The content of this paper is built on the fact that foreign direct investments have the potential to influence the structure and quality of economic development and competitiveness that many scientific researches and studies have already confirmed. The paper presents entrepreneurial environment as a significant factor for increasing country’s competitiveness. It clarifies and proves relationship between entrepreneurial environment, or more precisely its barriers, and foreign direct investment inflows. The starting point is identification of the barriers of the Slovak entrepreneurial environment according to Doing Business 2012 by comparing Slovakia with the Visegrad Four Countries. Subsequently relationship of barriers (paying taxes, trading across borders, enforcing contracts, protecting investors and FDI inflows on the sample of 25 leading countries for foreign investors according to FDI Confidence Index (Brazil, China, Germany, India, USA etc. is tested by Spearman's rank correlation test. The paper specifies barriers of EE, which removal would have a real impact on increasing FDI inflows into economy of Slovakia with relevant effects on its competitiveness.Research limitations were determined by the availability of statistical data, relatively large sample of surveyed economies in the world and comparison with other assessments (indices of FDI and competitiveness of countries. Given the limits on the scope of a magazine article, we will continue in our research in more detail in the future. Specific attention in this context will be devoted to the impact of investment incentives on FDI inflows. Methodology and selection of applied testing tool in synergy with selected statistical set of datas can bring new approach to the studied field and can stimulate extension of possibilities reached in this paper. The value of this paper lays in the specification of weak points of the Slovak entrepreneurial environment in the context of  its location

    Objectives It is not known which of the many asthma-specific quality of life (QoL) questionnaires best capture the lived experience of people with asthma. The objective of this study was to explore patients' views of three commonly used asthma-specific QoL questionnaires. Design Qualitative study using semistructured interviews. Setting Primary and secondary care in Brighton and Hove, UK. Participants 30 adult people with a physician-diagnosis of asthma who were asked to complete the Juniper Asthma Quality of Life Questionnaire (AQLQ-J), the Sydney Asthma Quality of Life Questionnaire (AQLQ-S) and the Living with Asthma Questionnaire (LWAQ) to elicit their views on the content validity of these. Results Thematic content analysis revealed a lack of congruence between the concerns of people with asthma and the questionnaire content in terms of missing (eg, allergies) and irrelevant (eg, smoky restaurants) content. The AQLQ-J was perceived as a ‘narrow’, ‘medical’ questionnaire focused on symptoms, the environment and functional ability. In contrast, the LWAQ and the AQLQ-S were perceived to be ‘non-medical’. The LWAQ was described as a ‘test’ and as a wide-ranging, embracing and holistic questionnaire. Its strong emotional focus was irritating to some. The AQLQ-S was described as a simple, quick and easy questionnaire, although there was a perception that it was lacking in depth. Conclusions Patient interviews highlighted strengths and shortcomings in the content validity of these three asthma-specific questionnaires. For patients, the AQLQ-S content seemed to be the most pertinent in its adequacy of coverage of medical, social and emotional aspects of health-related QoL in asthma. PMID:28007706

    The strongest predictor of nurse job dissatisfaction and intent to leave is that of stress in the practice environment. Good communication, control over practice, decision making at the bedside, teamwork, and nurse empowerment have been found to increase nurse satisfaction and decrease turnover. In this article we share our experience of developing a rapid-design process to change the approach to performance improvement so as to increase engagement, empowerment, effectiveness, and the quality of the professional practice environment. Meal and non-meal breaks were identified as the target area for improvement. Qualitative and quantitative data support the success of this project. We begin this article with a review of literature related to work environment and retention and a presentation of the frameworks used to improve the work environment, specifically Maslow's theory of the Hierarchy of Inborn Needs and the National Database of Nursing Quality Indicators Survey. We then describe our performance improvement project and share our conclusion and recommendations.

China's population could double to 2.4 billion by 2060. About 14 million people are added every year. China has about 300 million women of childbearing age. Even with 1 child per woman, population would grow by 300 million. 18 provinces have population growth over the national average of 1.49%. Many of these provinces are also provinces with high population density, high poverty ratios, and higher than 2 birth orders. The highest growth is in western China. Poor households have a lower quality of life, more disabled members, high rates of endemic disease, and illiteracy. Among the very poor without adequate food or clothing, environmental protection is a meaningless concept. Poverty alleviation strategies have shifted from relief to economic development. State support combined with local resources in a pooling approach pays for poverty alleviation programs. The central government's share will increase until the year 2000. The number of poor was 80 million in 1994 (9% of total population) living in 592 poor counties in remote and mountainous areas. The number of poor was reduced to 65 million in 1996. An integrated approach of family planning and poverty alleviation operates in Jinzhai County of Anhui province. China is determined to reorient to a "service-oriented, client- centered, woman-sensitive, and rural-emphasized approach."

    Full Text Available The microbes that inhabit particular environments must be able to perform molecular functions that provide them with a competitive advantage to thrive in those environments. As most molecular functions are performed by proteins and are conserved between related proteins, we can expect that organisms successful in a given environmental niche would contain protein families that are specific for functions that are important in that environment. For instance, the human gut is rich in polysaccharides from the diet or secreted by the host, and is dominated by Bacteroides, whose genomes contain highly expanded repertoire of protein families involved in carbohydrate metabolism. To identify other protein families that are specific to this environment, we investigated the distribution of protein families in the currently available human gut genomic and metagenomic data. Using an automated procedure, we identified a group of protein families strongly overrepresented in the human gut. These not only include many families described previously but also, interestingly, a large group of previously unrecognized protein families, which suggests that we still have much to discover about this environment. The identification and analysis of these families could provide us with new information about an environment critical to our health and well being.

    The specification of decoction pieces and quality uniformity are the important factors to influence the efficacy of clinical medicine. Considering the deficiency of diversity, poor quality uniformity and confusion of decoction pieces specifications, we first propose a new idea of precision decoction pieces (PDP) based on clinical demands and fresh-processed technology. In order to explain the idea, a study case of aconite SUP is provided, including the optimized specification design, processing technology, extraction effects, quality uniformity, and toxic and efficacy variation and so on. The results showed that preparing 5 mm PDP by fresh-cutting is rather simple and practicable, with high efficiency and large yield; then, this technology could significantly decrease the ingredients loss and increase the efficacy components; moreover, it was helpful for achieving the quality uniformity and best extraction effects. This work revealed the quality superiority of PDP, and provided a good strategy and example for the standard of decoction pieces specification and modernization of processing technology.

    To determine the impact of nurse work environment and staffing on nurse outcomes, including job satisfaction and burnout, and on quality of nursing care. Secondary data analysis of the 2007 Thai Nurse Survey. The sample consisted of 5,247 nurses who provided direct care for patients across 39 public hospitals in Thailand. Multivariate logistic regression was used to estimate the impact of nurse work environment and staffing on nurse outcomes and quality of care. Nurses cared for an average of 10 patients each. Forty-one percent of nurses had a high burnout score as measured by the Maslach Burnout Inventory; 28% of nurses were dissatisfied with their job; and 27% rated quality of nursing care as fair or poor. At the hospital level, after controlling for nurse characteristics (age, years in unit), the addition of each patient to a nurse's workload was associated with a 2% increase in the odds on nurses reporting high emotional exhaustion (odds ratio [OR] 1.02; 95% confidence interval [CI] 1.00-1.03; p work environments were about 30% less likely to report fair to poor care quality (OR 0.69; 95% CI 0.48-0.98; p work environments. The addition of each patient to a nurse's workload was associated with a 4% increase in the odds on nurses reporting quality of nursing care as fair or poor (OR 1.04; 95% CI 1.02-1.05; p work environments and nurse staffing in Thai hospitals holds promise for reducing nurse burnout, thus improving nurse retention at the hospital bedside as well as potentially improving the quality of care.

    Full Text Available The purpose of this paper was to explore the utility of an electronic nose to detect the quality of litchi fruit stored in different environments. In this study, a PEN3 electronic nose was adopted to test the storage time and hardness of litchi that were stored in three different types of environment (room temperature, refrigerator and controlled-atmosphere. After acquiring data about the hardness of the sample and from the electronic nose, linear discriminant analysis (LDA, canonical correlation analysis (CCA, BP neural network (BPNN and BP neural network-partial least squares regression (BPNN-PLSR, were employed for data processing. The experimental results showed that the hardness of litchi fruits stored in all three environments decreased during storage. The litchi stored at room temperature had the fastest rate of decrease in hardness, followed by those stored in a refrigerator environment and under a controlled-atmosphere. LDA has a poor ability to classify the storage time of the three environments in which litchi was stored. BPNN can effectively recognize the storage time of litchi stored in a refrigerator and a controlled-atmosphere environment. However, the BPNN classification of the effect of room temperature storage on litchi was poor. CCA results show a significant correlation between electronic nose data and hardness data under the room temperature, and the correlation is more obvious for those under the refrigerator environment and controlled-atmosphere environment. The BPNN-PLSR can effectively predict the hardness of litchi under refrigerator storage conditions and a controlled-atmosphere environment. However, the BPNN-PLSR prediction of the effect of room temperature storage on litchi and global environment storage on litchi were poor.

    Few studies link organizational variables and outcomes to quality indicators. This approach would expose operant mechanisms by which work environment characteristics and organizational outcomes affect clinical effectiveness, safety, and quality indicators. What are the predominant psychosocial variables in the explanation of organizational outcomes and quality indicators (in this case, medication errors and length of stay)? The primary objective of this study was to link the fields of evidence-based practice to the field of decision making, by providing an effective model of intervention to improve safety and quality. The study involved healthcare workers (n = 243) from 13 different care units of a university affiliated health center in Canada. Data regarding the psychosocial work environment (10 work climate scales, effort/reward imbalance, and social support) was linked to organizational outcomes (absenteeism, turnover, overtime), to the nurse/patient ratio and quality indicators (medication errors and length of stay) using path analyses. The models produced in this study revealed a contribution of some psychosocial factors to quality indicators, through an indirect effect of personnel- or human resources-related variables, more precisely: turnover, absenteeism, overtime, and nurse/patient ratio. Four perceptions of work environment appear to play an important part in the indirect effect on both medication errors and length of stay: apparent social support from supervisors, appreciation of the workload demands, pride in being part of one's work team, and effort/reward balance. This study reveals the importance of employee perceptions of the work environment as an indirect predictor of quality of care. Working to improve these perceptions is a good investment for loyalty and attendance. In general, better personnel conditions lead to fewer medication errors and shorter length of stay. © Sigma Theta Tau International.

    The objective of the U.S. Department of Energy Office of Nuclear Energy Advanced Modeling and Simulation Nuclear Waste Management Integrated Performance and Safety Codes (NEAMS Nuclear Waste Management IPSC) is to provide an integrated suite of computational modeling and simulation (M&S) capabilities to quantitatively assess the long-term performance of waste forms in the engineered and geologic environments of a radioactive-waste storage facility or disposal repository. These M&S capabilities are to be managed, verified, and validated within the NEAMS Nuclear Waste Management IPSC quality environment. M&S capabilities and the supporting analysis workflow and simulation data management tools will be distributed to end-users from this same quality environment. The same analysis workflow and simulation data management tools that are to be distributed to end-users will be used for verification and validation (V&V) activities within the quality environment. This strategic decision reduces the number of tools to be supported, and increases the quality of tools distributed to end users due to rigorous use by V&V activities. This report documents an evaluation of the needs, options, and tools selected for the NEAMS Nuclear Waste Management IPSC quality environment.

    Full Text Available The medical units represent a challenge for the building services engineers who are often put in difficulty to ensure the indoor optimal conditions. The destination variety of the indoor environment in such buildings and the different internal thermal loads lead to discomfort zones, for all involved users. The requirements imposed by standards lead often to dissatisfaction for the users: while some of the medical staff asks for low temperatures, others feel discomfort and often the patients have thermoregulatory problems due to this non-homogeneity of thermal conditions found.Several sets of survey studies were made in a large emergency hospital located in Romania of 1070 beds. Medical and non-medical team participated in this study regarding the indoor quality from different work-zones of this hospital. The zones studied were: internal medicine, cardiology, gastroenterology, hematology, neurology, neurological recovery, the emergency unit, and also functional and auxiliary areas: dietetics, administrative, statistics, etc.All the queried persons had to response to a 15 minutes questionnaire, where local and global comfort questions were asked, in addition to specific characteristics like gender, age etc.The results have shown high differences from one zone to another and more of that, high differences between the categories of personnel. Uncomfortable thermal sensations, lack of fresh air and important level of polluted air, noise or lack of space are just some of the problems met in hospital environment.

    Full Text Available Background: Poor school performance in children causes significant stress to parents. Aims: To analyze the quality of life (QOL of parents having a child with newly diagnosed specific learning disability (SpLD and to evaluate the impact of clinical and socio-demographic characteristics on their QOL. Design: Cross-sectional questionnaire-based study. Setting: Learning disability clinic in tertiary care hospital. Materials and Methods: From June 2006 to February 2007, 150 parents (either mother or father of children consecutively diagnosed as having SpLD were enrolled. Parent′s QOL was measured by the WHOQOL-100 instrument which is a generic instrument containing 25 facets of QOL organized in six domains. Statistical Analysis Used: Independent samples t-test, one-way analysis of variance, and multiple regression analysis were carried out for statistical significance. Results: Mean age of parents was 42.6 years (SD 5.5; mothers to fathers ratio 1.3:1; and 19 (12.7% were currently ill. Only four WHOQOL-100 domains (psychological > social relationships > environment > spiritual and five WHOQOL-100 facets (leisur > pfeel > energy > esteem > sex contributed significantly to their "overall" QOL. Female gender, being currently ill, being in paid work, and having a male child were characteristics that independently predicted a poor domain/facet QOL score. Conclusions: The present study has identified domains and facets that need to be addressed by counselors for improving overall QOL of these parents. Initiating these measures would also improve the home environment and help in the rehabilitation of children with SpLD.

    Full Text Available Reviewing the test specifications to improve the quality of language tests may be a routine process in professional testing systems. However, there is a paucity of research about the effect of specifications review on improving the quality of small-scale tests. The purpose of the present study was twofold: how specifications review could help improve the validity of a test in the context of assessment for learning (AFL and to what extent qualitative review of items can identify poor ones. To this end, a group of trained test specifications reviewers (No = 7 provided feedback on the specifications of a test and the quality of the items. Analysis of feedback showed that pedagogical concerns naturally emerged during the specifications review and led to concrete suggestions on how the specifications could be revised so that the resulting test could become more useful in a classroom context. Moreover, the test items were administered to a group of (No = 40 test-takers and a set of quantitative item analyses was carried out. Comparison of the results of qualitative judgment of reviewers with the quantitative analyses showed about 38 % of the items suggested for revision by the reviewers were also identified as poor by the classical test theory (CTT analysis. The findings highlight the potential of specifications review as part of the a priori validation of tests in small-scale assessments where conducting statistical analysis is not usually feasible.

    2010-10-01

    This paper is a report of a study of the relationship between work environment characteristics and neonatal intensive care unit nurses' perceptions of care rationing, job outcomes, and quality of care. International evidence suggests that attention to work environments might improve nurse recruitment and retention, and the quality of care. However, comparatively little attention has been given to neonatal care, a specialty where patient and nurse outcomes are potentially quite sensitive to problems with staffing and work environments. Over a 6-month period in 2007-2008, a questionnaire containing measures of work environment characteristics, nursing care rationing, job satisfaction, burnout and quality of care was distributed to 553 nurses in all neonatal intensive care units in the province of Quebec (Canada). A total of 339 nurses (61.3%) completed questionnaires. Overall, 18.6% were dissatisfied with their job, 35.7% showed high emotional exhaustion, and 19.2% rated the quality of care on their unit as fair or poor. Care activities most frequently rationed because of insufficient time were discharge planning, parental support and teaching, and comfort care. In multivariate analyses, higher work environment ratings were related to lower likelihood of reporting rationing and burnout, and better ratings of quality of care and job satisfaction. Additional research on the determinants of nurse outcomes, the quality of patient care, and the impact of rationing of nursing care on patient outcomes in neonatal intensive care units is required. The Neonatal Extent of Work Rationing Instrument appears to be a useful tool for monitoring the extent of rationing of nursing care in neonatal units. © 2010 Blackwell Publishing Ltd.

    To investigate fertilization and embryo quality of dysmorphic mature oocytes with specific morphological abnormalities obtained from intracytoplasmic sperm injection (ICSI). The fertilization rate (FR) and embryo quality were compared among 58 dysmorphic and 42 normal form oocytes (control 1) obtained from 35 consecutive ICSI cycles, each of which yielded at least one dysmorphic mature oocyte, performed over a period of 5 years. The FR and embryo quality of 441 normal form oocytes from another 119 ICSI cycles that did not involve dysmorphic oocytes served as control 2. Dysmorphic oocytes were classified as having a dark cytoplasm, cytoplasmic granularity, cytoplasmic vacuoles, refractile bodies in the cytoplasm, smooth endoplasmic reticulum in the cytoplasm, an oval shape, an abnormal zona pellucida, a large perivitelline space, debris in the perivitelline space, or an abnormal polar body (PB). The overall FR was significantly lower in dysmorphic oocytes than in normal form oocytes in both the control 1 and control 2 groups. However, embryo quality in the dysmorphic oocyte group and the normal form oocyte groups at day 3 was similar. The FR and embryo quality were similar in the oocyte groups with a single abnormality and multiple abnormalities. Specific abnormalities related with a higher percentage of top-quality embryos were dark cytoplasm (66.7%), abnormal PB (50%), and cytoplasmic vacuoles (25%). The fertilization potential of dysmorphic oocytes in our study was lower, but their subsequent embryonic development and embryo quality was relatively good. We were able to define several specific abnormalities related with good or poor embryo quality.

    Full Text Available ABSTRACT Light is one of the factors that most affect crop growth and yield. However, the control of light intensity is difficult, because, under certain environmental conditions, light energy may exceed or limit the capacity of plants to use it. In this sense, the productive behavior of plant species in shaded environments needs to be known. This study aimed to evaluate the effect of different shaded environments with black shade nets [0 (full sun, 35 and 50%, and overlap 35 + 50% shading nets] on flowering, yield and quality of inflorescences of Heliconia psittacorum (cv. 'Golden Torch'. The shaded environments caused a reduction in the number of days for inflorescence emergence and in the cycle of H. psittacorum (cv. 'Golden Torch'. The yield and quality of inflorescences of plants grown under full-sun conditions (0% shading were impaired. The results indicate that, for a better management of the crop environment, aiming yield and quality of inflorescences of H. psittacorum (cv. 'Golden Torch', the use of black shade nets with 50% shading is recommended.

    Living under intense predation pressure, octopuses evolved an effective and impressive camouflaging ability that exploits features of their surroundings to enable them to "blend in." To achieve such background matching, an animal may use general resemblance and reproduce characteristics of its entire surroundings, or it may imitate a specific object in its immediate environment. Using image analysis algorithms, we examined correlations between octopuses and their backgrounds. Field experiments show that when camouflaging, Octopus cyanea and O. vulgaris base their body patterns on selected features of nearby objects rather than attempting to match a large field of view. Such an approach enables the octopus to camouflage in partly occluded environments and to solve the problem of differences in appearance as a function of the viewing inclination of the observer.

Such an approach enables the octopus to camouflage in partly occluded environments and to solve the problem of differences in appearance as a function of the viewing inclination of the observer.

    Barley has been in use as food and fodder for thousands of years, and also used currently as themost important raw material in malting and brewing. The quality of malt barley is not much satisfied with therequirement by malting and brewing industry worldwide, although the great effort has been devoted to its im-provement through breeding and agronomy. The quality of malt barley is involved in many physical and chemi-cal traits, including hydrolytic enzymes. Of them, kernel protein content, beta-amylase activity, beta-glucancontent and kernel plumpness have dramatic influence on malting or brewing quality. The expression of thesequality parameters varies greatly in genotypes and is easily changed by diverse environments and agronomicpractices. This paper reviewed the important role of various parameters influencing the quality of malt barleyand the effect of different factors on them.

    Agriculture is a high-hazard industry that employs a large number of young workers below the age of 25. Recent studies have documented a strong positive correlation between quality management in agriculture and occupational safety as perceived by agricultural workers. Younger workers have been found to be at higher risk for occupational injuries and fatalities in agriculture. Furthermore, college students in agriculture have minimal exposure to safety and quality management principles in their coursework and thus may not be aware that the two concepts are associated Little research has studied how young workers perceive the relationship between safety and quality and how these perceptions vary based on demographic characteristics. This study builds on prior research that measured the interactions between employee perceptions of safety and quality in an agricultural work environment. Data were collected using a survey instrument adapted from a previously validated instrument. Analysis of 1017 responses showed that students perceived a high impact of quality practices on the reduction of safety hazards and safety incidents. Students' perceptions of quality and safety in agricultural work environments varied by gender, with female students perceiving the relationship between the two at a higher level than males. No significant difference in perceptions was observed based on students' academic classification, age group, field of study, or childhood environment. This study demonstrates that despite limited academic training in safety and quality, pre-professionals perceive the implementation of quality management as a very important factor in mitigating safety hazards and safety incidents. In addition, this study suggests that current academic training in these disciplines must be modified, since no differences in students' perceptions were observed based on academic classification or field of study.

    2015-09-01

    Substantial research documents higher pollution levels in minority neighborhoods, but little research evaluates how residents perceive their own communities' pollution risks. According to "Neighborhood stigma" theory, survey respondents share a cultural bias that minorities cause social dysfunction, leading to over-reports of dysfunction in minority communities. This study investigates perceptions of residential outdoor air quality by linking objective data on built and social environments with multiple measures of pollution and a representative survey of Chicago residents. Consistent with the scholarly narrative, results show air quality is rated worse where minorities and poverty are concentrated, even after extensive adjustment for objective pollution and built environment measures. Perceptions of air pollution may thus be driven by neighborhood socioeconomic position far more than by respondents' ability to perceive pollution. The finding that 63.5% of the sample reported excellent or good air quality helps to explain current challenging in promoting environmental action.

    It is one of the important strategies during the poverty alleviation to maintain a basic balance between the eco-environment and economic development in poor areas. Taking the whole 20 counties in Lüliang national contiguous special poverty-stricken areas and the surrounding 36 counties as multi-type and multi-scale typical study areas, the relationship between eco-environment quality and poverty in the poverty-stricken areas was explored in this paper. Firstly, the region's ecological poverty index system was systematically built, and by integrated use of the subjective and objective weighting method, the ecological environment quality was evaluated in the perspective of natural environment. Then, the coupling coordination degree was calculated by coupling the ecological environment quality index and the average disposable income. Finally, the spatial variation was analyzed in detail respectively at provincial, city and county scales. Results showed that as a whole, the spatial autocorrelation coefficient of coupling coordination degree was relatively higher in the study area, and the coupling coordination degree in the eastern part was higher than that in the western part; the whole coupling coordination degree in Shanxi Province was slightly higher than in Shaanxi Province; the national poverty counties presented a state of recession, and their coordinated development degrees were far lower than that of non-national poverty counties.

    What does one feel when one uses virtual reality? How does this experience differ from the experience associated with "real life" activities and situations? To answer these questions, we used the Experience Sampling Method (ESM), a procedure that allows researchers to investigate the daily fluctuations in the quality of experience through on-line self reports that participants fill out during daily life. The investigation consisted in one-week ESM observation (N = 42). During this week, participants underwent two virtual reality sessions: Immediately after the exposure to virtual environments, they were asked to complete a ESM report. For data analysis, experiential variables were aggregated into four dimensions: Mood, Engagement, Confidence, and Intrinsic Motivation Intrinsic Motivation. Findings showed that virtual experience is characterized by a specific configuration, which comprises significantly positive values for affective and cognitive components. In particular, positive scores of Mood suggest that participants perceived VR as an intrinsically pleasurable activity, while positive values of Engagement indicate that the use of VR and the experimental task provided valid opportunities for action and high skill investment. Furthermore, results showed that virtual experience is associated with Flow, a state of consciousness characterized by narrowed focus of attention, deep concentration, positive affect and intrinsic reward. Implications for VR research and practice are discussed.

    As an integral part of tolerance design in the context of design for six sigma, determining optimal product specifications has become the focus of increased activity, as manufacturing industries strive to increase productivity and improve the quality of their products. Although a number of research papers have been reported in the research community, there is room for improvement. Most existing research papers consider determining optimal specification limits for a single quality characteristic. In this paper, we develop the modeling and optimization procedures for optimum circular and spherical configurations by considering multiple quality characteristics. The concepts of multivariate quality loss function and truncated distribution are incorporated. This has never been adequately addressed, nor has been appropriately applied in industry. A numerical example is shown and comparison studies are made.

    Although a substantial body of literature has provided evidence supporting the positive effects of natural environments on well-being, little has been known about the specific spatial patterns of urban nature in promoting health-related quality of life (HRQOL) among children. This study assessed the association that the urban natural environment measured by landscape spatial patterns may have with obesity and HRQOL among Hispanic children. Ninety-two 4th and 5th grade students were recruited from Houston, Texas, and the Pediatric Quality of Life Inventory (PedsQL) was used to capture the children's HRQOL. The quality of urban natural environments was assessed by quantifying the landscape spatial patterns, using landscape indices generated by Geographic Information Systems and remote sensing. From the bivariate analyses, children's body mass index showed a significantly negative association with their HRQOL. After controlling for socio-demographic factors, the results revealed that larger and more tree areas were positively correlated with children's HRQOL. In addition, those children living in areas with tree patches further apart from each other showed higher HRQOL. This research adds to the current multi-disciplinary area of research on environment-health relationships by investigating the roles of urban greeneries and linking their spatial structures with children's HRQOL.

    What are the long-term effects of childhood experience on brain development? Research with animals shows that the quality of environmental stimulation and parental nurturance both play important roles in shaping lifelong brain structure and function. Human research has so far been limited to the effects of abnormal experience and pathological development. Using a unique longitudinal dataset of in-home measures of childhood experience at ages 4 and 8 and MRI acquired in late adolescence, we were able to relate normal variation in childhood experience to later life cortical thickness. Environmental stimulation at age 4 predicted cortical thickness in a set of automatically derived regions in temporal and prefrontal cortex. In contrast, age 8 experience was not predictive. Parental nurturance was not predictive at either age. This work reveals an association between childhood experience and later brain structure that is specific relative to aspects of experience, regions of brain, and timing.

    Objective The main objective of this study was to determine the relationship between the characteristics of nurses' work environments in hospitals in the Spanish National Health System (SNHS) with nurse reported quality of care, and how care was provided by using different shifts schemes. The study also examined the relationship between job satisfaction, burnout, sleep quality and daytime drowsiness of nurses and shift work. Methods This was a multicentre, observational, descriptive, cross-sectional study, centred on a self-administered questionnaire. The study was conducted in seven SNHS hospitals of different sizes. We recruited 635 registered nurses who worked on day, night and rotational shifts on surgical, medical and critical care units. Their average age was 41.1 years, their average work experience was 16.4 years and 90% worked full time. A descriptive and bivariate analysis was carried out to study the relationship between work environment, quality and safety care, and sleep quality of nurses working different shift patterns. Results 65.4% (410) of nurses worked on a rotating shift. The Practice Environment Scale of the Nursing Work Index classification ranked 20% (95) as favourable, showing differences in nurse manager ability, leadership and support between shifts (p=0.003). 46.6% (286) were sure that patients could manage their self-care after discharge, but there were differences between shifts (p=0.035). 33.1% (201) agreed with information being lost in the shift change, showing differences between shifts (p=0.002). The Pittsburgh Sleep Quality Index reflected an average of 6.8 (SD 3.39), with differences between shifts (p=0.017). Conclusions Nursing requires shift work, and the results showed that the rotating shift was the most common. Rotating shift nurses reported worse perception in organisational and work environmental factors. Rotating and night shift nurses were less confident about patients' competence of self-care after discharge. The

    The quality of the healthy environment in a neighborhood city is decreasing in number. According to the government regulation, Act No. 26 of 2007, a city should have 20% of green areas from the total area of the city. Now, Semarang only has 7.5% of green areas from the total city area. One of the efforts made by the Government of Semarang is the establishment of a greenbelt in Jatibarang area. It consists of several parts, namely, the reservoirs in the green belt area and also the plant zone in other sectors. The reservoir has a function as the controller of water resources sustainability where the crops serve as the balance for the combination. Thus, it is interesting to study how the interplay of these two functions in a green belt area. The primary data used in this study was obtained from the locus of research by direct observation, interview, and physical data collection. Based on the data collection, data was then processed and analyzed in accordance with the indicators that had been compiled based on theories of reservoirs, green belts, and the quality of the urban environment. Government regulations regarding with the greenbelt and tanks were also used as references in the discussion. The research found out that the presence of the reservoir and the plants in the green belt of Jatibarang can improve the function of the green belt optimally which is a real influence for the improvement of the environment quality, especially water. The Greenbelt was divided into four zones, namely the Arboretum, Argo - Forestry, Ecotourism, Buffer - Zone also made the region became a beautiful greenbelt that brought a positive influence to environmental quality.

    Studies have shown that natural gas hydrates located near a mud volcano in Lake Baikal contain high concentrations of ethane. Gas hydrates absorb and release large amounts of latent heat during their formation and dissociation processes. In this study, the specific heat of synthetic methane and ethane hydrates were measured under high pressure using a heat-flow calorimeter. The aim of the study was to develop an improved understanding of the thermal environment of gas hydrate-bearing sediments in submarine and sublacustrine environments. Ice was placed in 2 sampling cells and pressurized with methane and ethane at 5 MPa and 2 MPa. After the gas hydrates formed, the samples were then heated from 263 K to 288 K. An analysis of data obtained from the experiment showed that large negative heat flow peaks corresponding with methane gas hydrate dissociation occurred in temperature ranges of 279 to 282 K at a pressure of 5 MPa, and at temperatures of 283-286 K at 2 MPa for the ethane gas hydrate. Future experiments with the calorimeter will be conducted at higher pressure ranges. 15 refs., 3 figs.

    The precipitation electrons in the auroral environment are highly variable in their energy and intensity in both space and time. As such they are a source of potential hazard to the operation of the Space Shuttle and other large spacecraft operating in polar orbit. In order to assess these hazards both the average and extreme states of the precipitating electrons must be determined. Work aimed at such a specification is presented. First results of a global study of the average characteristics are presented. In this study the high latitude region was divided into spatial elements in magnetic local time and corrected geomagnetic latitude. The average electron spectrum was then determined in each spatial element for seven different levels of activity as measured by K sub p using an extremely large data set of auroral observations. Second a case study of an extreme auroral electron environment is presented, in which the electrons are accelerated through field aligned potential as high as 30,000 volts and in which the spacecraft is seen to charge negatively to a potential approaching .5 kilovolts.

  7. Movement dependence and layer specificity of entorhinal phase precession in two-dimensional environments.

    Directory of Open Access Journals (Sweden)

    Eric Reifenstein

    Full Text Available As a rat moves, grid cells in its entorhinal cortex (EC discharge at multiple locations of the external world, and the firing fields of each grid cell span a hexagonal lattice. For movements on linear tracks, spikes tend to occur at successively earlier phases of the theta-band filtered local field potential during the traversal of a firing field - a phenomenon termed phase precession. The complex movement patterns observed in two-dimensional (2D open-field environments may fundamentally alter phase precession. To study this question at the behaviorally relevant single-run level, we analyzed EC spike patterns as a function of the distance traveled by the rat along each trajectory. This analysis revealed that cells across all EC layers fire spikes that phase-precess; indeed, the rate and extent of phase precession were the same, only the correlation between spike phase and path length was weaker in EC layer III. Both slope and correlation of phase precession were surprisingly similar on linear tracks and in 2D open-field environments despite strong differences in the movement statistics, including running speed. While the phase-precession slope did not correlate with the average running speed, it did depend on specific properties of the animal's path. The longer a curving path through a grid-field in a 2D environment, the shallower was the rate of phase precession, while runs that grazed a grid field tangentially led to a steeper phase-precession slope than runs through the field center. Oscillatory interference models for grid cells do not reproduce the observed phenomena.

    Full Text Available The aim of the paper was to investigate how the quality of family environment is related to the child's adaptation capabilities. Child's adaptation was evaluated with a special assessment called SPP-3 (Systematic Psychological Assessment of a 3-year Old Child, that screens the population of 3-year olds to look for inadequate adaptation patterns. I assumed that in families where parents have higher education and where the environment is more stimulating children will show more effective and adaptive behaviour. Seventy-five children and parents who attended the psychological assessment in their regional hospitals first concluded the psychological examination (SPP-3 and then filled-in two questionnaires: The Family Environment Questionnaire (Zupančič, Podlesek, & Kavčič, 2004 and The Home Literacy Environment Questionnaire (Marjanovič Umek, Podlesek, & Fekonja, 2005. The results showed that quality of family environment does effect the child's adaptive capabilities and is associated with parental level of education. Of special importance for the child's socialization is the parents' ability to use effective control (to have consistent and clear demands. Hypothesis that the level of parental education affects the child's adaptation capabilities was not confirmed. Perhaps the parents' relations with the child are of greater importance, and these are probably not related to parents' education. The results show that child's adaptation capabilities are associated with parenting methods, so preventive psychological counselling may also be used to help parents choose more effective methods in order to allow the child to develop effective adaptive behaviour.

    Durum wheat is one of the most important agricultural crops in the Mediterranean area. In addition to yield, grain quality is very important in wheat markets because of the demand for high-quality end products such as pasta, couscous and bulgur wheat. Grain quality is directly affected by several...... agronomic and environmental factors. Our objective is to determine the general principles underlying how, in Mediterranean environments, grain protein content (GPC) is affected by these factors and provide a system model with high predictive ability. We initially evaluated the capability of the Delphi...

    2004-10-01

    The purpose of this paper is to summarize the state of the art in measuring quality of life in haemophila populations. The paper reviews the measures recently included in haemophila trials in the published literature. It also summarizes the development of four new disease-specific measures of health-related quality of life. Two of these were developed for children (the Haemo-QoL and the CHO-KLAT), and two for adults (the Hemofilia-QoL and the Hemolatin-QoL). These new measures show promise for use in clinical trials. Further research is in progress to complete the psychometric testing and cross-cultural validation.

    Full Text Available The xenobiotics introduced into the environment are the effect of human activities. It is especially soil contamination that leads to degradation of soils, which may finally be referred to the biological imbalance of the ecosystem. Normally chemical methods are used for the assessment of soil’s quality. Unfortunately, they are not always quick and inexpensive. Therefore, the practice and the science at environmental monitoring more frequently employ biological methods. Most of them meet the above mentioned conditions and become a supplement of routine laboratory practices. This publication shows an overview of selected common biological methods used to estimate the quality of the environment. The first part of the paper presents biomonitoring as a first step of environmental control which relies on the observation of indicator organisms. The next section was dedicated to the bioassays, indicating the greater or lesser practical applications confirmed by literature on the subject. Particular attention has been focused on phytotests and the tests based on the invertebrates.

    Indoor air quality monitoring in healthcare environment has become a critical part of hospital management and policy. Manual air sampling and analysis are cost-inhibitive and do not provide real-time air quality data and response measures. In this month-long study over 14 sampling locations in a public hospital in Taiwan, we observed a positive correlation between CO(2) concentration and population, total bacteria, and particulate matter concentrations, thus monitoring CO(2) concentration as a general indicator for air quality could be a viable option. Consequently, an intelligent environmental monitoring system consisting of a CO(2)/temperature/humidity sensor, a digital plug, and a ZigBee Router and Coordinator was developed and tested. The system also included a backend server that received and analyzed data, as well as activating ventilation and air purifiers when CO(2) concentration exceeded a pre-set value. Alert messages can also be delivered to offsite users through mobile devices.

    Veolia Water Solutions and Technologies has significant experience managing boiler water chemistry and is the world's largest manufacturer of evaporation systems. The company has conducted extensive testing and analysis for produced water evaporation distillate from multiple facilities. In order to produce boiler feed water, evaporation of produced water is used at several steam assisted gravity drainage (SAGD) facilities. There are no official guidelines for the required quality of evaporator distillate to feed a once through steam generator (OTSG) or high pressure industrial watertube boiler (IWT) that will produce injection steam. This paper presented a basis for a fit-for-purpose specification for IWT boilers as well as data on the performance of a Vapor Washer, which produces high quality distilled water that meets fit-for-purpose specifications even during normal variations in feed conditions. Specifically, the paper discussed boiler water requirements for steam injection IWTs; the quality of distillate from a produced water evaporator; the benefits of vapour washing to maintain distillate quality; and suggested boiler chemistry limits for a fit-for-purpose specification. Oxygen, iron, and copper were discussed as being implicated with corrosion and reaction in boilers. Hardness contaminants such as calcium and magnesium were also presented. Suggested limits for boiler water in the fit-for-purpose specification were also presented for silica, total alkalinity, free OH alkalinity, and total dissolved solids in steam. It was concluded that foaming episodes can occur in produced water evaporators due to normal variations, and the distillate can fail to meet the fit-for-purpose specification during foam upsets. 3 refs., 9 figs.

    This cross-sectional study explored the relationships among family ritual meaning, cohesion, conflict, and health-related quality of life (both specific to chronic health conditions and in general), and the emotional and behavioral problems reported by youths with asthma. Participants included 149 Portuguese children and adolescents between the ages of 8 and 18 who had been diagnosed with asthma and attended outpatient services at three public hospitals. The results showed that stronger family ritual meaning predicted a more positive family environment (i.e., higher cohesion levels and lower conflict levels), better health-related quality of life, and fewer emotional and behavior problems in youths. Furthermore, family cohesion and conflict mediated the links between family ritual meaning and health-related quality of life, and emotional and behavioral problems. These results did not change after controlling for participant age, gender, and asthma severity. The findings of this study suggest that family ritual meaning contributes to the adaptation of youths with asthma via its positive association with the family environment. The implications for multicontextual interventions with families are briefly discussed with regard to the positive role of family rituals and of their potential as a modifiable factor in families with increased health challenges.

Panteleimon, Athens, GreeceBackground: No specific questionnaire has been developed to assess the health-related quality of life of thalassemia patients. Thus, the main objective of this study was to develop, according to psychometric standards, a self-administered Specific Thalassemia Quality of Life Instrument (STQOLI for adult patients.Methods: First, a qualitative phase was conducted to generate items and identify domains using the critical analysis incident technique and a literature review. A list of easily comprehensible, non-redundant items was defined using the Delphi technique and a pilot study on ten thalassemia patients. This phase involved both patients and experts. The second step was a quantitative validation phase comprising a study of 128 thalassemia patients in a single hospital. It was designed to select items, identify dimensions, and measure reliability and internal and concurrent validity. The psychometric and scaling properties of the proposed 41-item Specific Thalassemia Quality of Life Instrument were then assessed among patients recruited from the Thalassemia Unit at the General Hospital of Nikaia, Greece.Results: The final questionnaire had 41 items comprising four main domains and one global item about general health. The factorial structure was satisfactory (loading > 0.40 on each factor of the four domains for all items. Interscale correlations ranged from 0.06 to 0.78, Cronbach's α-coefficients were 0.78 for the psychosocial domain, 0.77 for the chelation domain, 0.72 for the transfusion domain, 0.81 for the disease and symptoms domain, and 0.840 for the total score of the questionnaire.Conclusion: The 41-item Specific Thalassemia Quality of Life Instrument seems to be a

    Lycopene is a naturally occurring red carotenoid compound that is found in watermelon. Lycopene has antioxidant properties. Lycopene content, sugar content and hollowheart resistance are subject to significant genotype×environment interaction (G×E), which makes breeding for these fruit quality traits difficult. The objectives of this study were to (i) evaluate the influence of years and locations on lycopene content, sugar content and hollowheart resistance for a set of watermelon genotypes, and (ii) identify genotypes with high stability for lycopene, sugar, and hollowheart resistance. A diverse set of 40 genotypes was tested over 3 years and 8 locations across the southern United States in replicated, multi-harvest trials. Lycopene was tested in a subset of 10 genotypes. Data were analyzed using univariate and multivariate stability statistics (BLUP-GGE biplot) using SASGxE and RGxE programs. There were strong effects of environment as well as G×E interaction on watermelon quality traits. On the basis of stability measures, genotypes were classified as stable or unstable for each quality trait. 'Crimson Sweet' is an inbred line with high quality trait performance as well as trait stability. 'Stone Mountain', 'Tom Watson', 'Crimson Sweet' and 'Minilee' were among the best genotypes for lycopene content, sugar content and hollowheart resistance. We developed a stability chart based on marketable yield and average ranking generated from different stability measures for yield attributes and quality traits. The chart will assist in choosing parents for improvement of watermelon cultivars. See http://cuke.hort.ncsu.edu/cucurbit/wmelon/wmelonmain.html.

    Full Text Available The idea of inclusive education raises the question of security of children with autism spectrum disorders (ASD. It is the imperative of the time to create teaching materials that promote the effective implementation of educational curriculum. However, we have to stress the fact that most of the evaluable nowadays teaching materials have been created spontaneously, without any reliable criteria. Our primary hypothesis is that children with ASD have specific features of visual perception that do not depend on the state of their intelligence, which is confirmed by empirical data obtained by the authors. Our secondary hypothesis, specified in the process of research, stipulates that children with ASD will differently perceive different graphic images executed in different styles. These findings are further confirmed by empirical data collected by the authors in the study of perception and understanding of different graphic images by children with ASD and mental retardation. On the basis of theoretical and empirical data we specified the criteria for graphic design products which play a pivotal role in the formation of school educational environment. In this respect we focus on the criteria for design materials (including design criteria provisions, formulated by Norman, which he addressed to practicing designers.

    Full Text Available We investigate the effect of internal control employees (ICEs on internal control quality. Using special survey data from Chinese listed firms, we find that ICE quality has a significant positive influence on internal control quality. We examine the effect of monitoring on this result and find that the effect is more pronounced for firms with strict monitoring environments, especially when the firms implement the Chinese internal control regulation system (CSOX, have higher institutional ownership or attach greater importance to internal control. Our findings suggest that ICEs play an important role in the design and implementation of internal control systems. Our study should be of interest to both top managers who wish to improve corporate internal control quality and regulators who wish to understand the mechanisms of internal control monitoring.

    OBJECTIVE. We identified the predictive factors of change in quality of life (QOL) after a distributed form of constraint-induced therapy (dCIT) among stroke survivors. METHOD. Seventy-four participants were treated with dCIT. We identified eight potential determinants of change: age, gender, side of lesion, time since stroke, cognitive status, motor impairment of the upper extremity, activities of daily living (ADLs), and instrumental ADLs (IADLs). The Stroke-Specific Quality of Life Scale (SS–QOL) was used to assess QOL. RESULTS. Right-sided lesion and onset >17 mo earlier determined greater improvement in the SS–QOL Energy domain. Onset >10 mo earlier, poorer IADL performance, and age >68 yr predicted improvement in the Family Role, Mobility, and Mood domains, respectively. CONCLUSION. Side of lesion, time since stroke, IADL performance, and age were the most important determinants of QOL in patients receiving stroke motor rehabilitation. PMID:23245783

    Refrigerated dough products use wheat flour as their primary ingredient, so the quality and chemical composition of the flour determine the quality of the final product. Six varieties of hard red spring wheat, grown in 3 locations in Minnesota, U.S.A., were evaluated for use in refrigerated dough products. Total arabinoxylan percentages in the flours ranged from 0.97 to 1.54. Xylanase activity of the flour was measured and ranged from 0.20 to 0.84 mU/g. An important factor in the suitability for refrigerated dough is the syruping during storage. A large amount of variability in dough syruping was observed among the varieties and locations when the extent of dough syruping was measured over a period of 10 d. The mean dough syruping on day 10 ranged from 2.05% to 14.83%. Despite the significant interaction effect of genotype and environment, 2 varieties, Glenn and Oklee, had lower dough syrup formation with greater stability across growing locations and storage days than other varieties. Practical Application: Refrigerated dough production is one of the fastest growing segments of the ready-to-use food industry. Well-formulated and processed refrigerated doughs are practical to consume and should stay fresh during extended periods of storage; thus, maintenance of dough quality during refrigeration is critical. This study was designed to perform the research on genotypic and environmental effects on variations in dough syruping during refrigeration storage of doughs from hard red spring wheats.

    The results of a simulator study conducted to compare and validate various ride quality prediction methods for use in assessing passenger/crew ride comfort within helicopters are presented. Included are results quantifying 35 helicopter pilots discomfort responses to helicopter interior noise and vibration typical of routine flights, assessment of various ride quality metrics including the NASA ride comfort model, and examination of possible criteria approaches. Results of the study indicated that crew discomfort results from a complex interaction between vibration and interior noise. Overall measures such as weighted or unweighted root-mean-square acceleration level and A-weighted noise level were not good predictors of discomfort. Accurate prediction required a metric incorporating the interactive effects of both noise and vibration. The best metric for predicting crew comfort to the combined noise and vibration environment was the NASA discomfort index.

    This study presents the effects of environmental pollution on the quality of domestic roof-harvested rainwater (DRHRW) using fuzzy comprehensive assessment (FCA). Seven metals (Cu, Cd, Pb, Zn, Fe, Ca, and Mg) and six water-quality parameters (Acidity, PO4 (3-), SO4 (2-), NO3 (-) , Cl(-), and pH) were investigated in DRHRW sampled from 12 sampling points each from Ibadan (residential) and Lagos (industrial) environments, Nigeria. The results of these parameters were formulated into membership function fuzzy matrices based on four contamination classifications of high, marginal, low, and poor qualities using regulatory limits as criteria. The products membership function matrices and weight matrices generated indices that classified the degree of anthropogenic activity impact on the sites. Results of FCA classified the DRHRW from residential environment as between high and marginal quality, whereas DRHRW from industrial environment is classified between marginal and low quality. Lead and Cd were major contaminants of concern found in these harvested water.

The contract awarded to the team was the Space Transportation System Operations Contract (STSOC). Our initial challenge was to accept responsibility for a very large, highly complex and fragmented collection of software from eleven different contractors and transform it into a coherent, operational baseline. Concurrently, we had to integrate a diverse group of people from eleven different companies into a single, cohesive team. Paramax executives recognized the absolute necessity to develop a business culture based on the concept of employee involvement to execute and improve the complex process of our new environment. Our executives clearly understood that management needed to set the example and lead the way to quality improvement. The total quality management policy and the metrics used in this endeavor are presented.

    RNA-sequencing (RNA-seq) is rapidly emerging as the technology of choice for whole-transcriptome studies. However, RNA-seq is not a bias free technique. It requires large amounts of RNA and library preparation can introduce multiple artifacts, compounded by problems from later stages in the process. Nevertheless, RNA-seq is increasingly used in multiple studies, including the characterization of tissue-specific transcriptomes from invertebrate models of human disease. The generation of samples in this context is complex, involving the establishment of mutant strains and the delicate contamination prone process of dissecting the target tissue. Moreover, in order to achieve the required amount of RNA, multiple samples need to be pooled. Such datasets pose extra challenges due to the large variability that may occur between similar pools, mostly due to the presence of cells from surrounding tissues. Therefore, in addition to standard quality control of RNA-seq data, analytical procedures for control of "biological quality" are critical for successful comparison of gene expression profiles. In this study, the transcriptome of the central nervous system (CNS) of a Drosophila transgenic strain with neuronal-specific RNAi of an ubiquitous gene was profiled using RNA-seq. After observing the existence of an unusual variance in our dataset, we showed that the expression profile of a small panel of marker genes, including GAL4 under control of a tissue specific driver, can identify libraries with low levels of contamination from neighboring tissues, enabling the selection of a robust dataset for differential expression analysis. We further analyzed the potential of profiling a complex tissue to identify cell-type specific changes in response to target gene down-regulation. Finally, we showed that trimming 5' ends of reads decreases nucleotide frequency biases, increasing the coverage of protein coding genes with a potential positive impact in the incurrence of systematic

    This study aims to describe generic and disease-specific quality of life (QOL) and its predictors among Chinese inpatients with schizophrenia. A total of 209 subjects participated in this study: 121 men and 88 women. Their ages ranged from 18 to 64, with a mean age of 33.85 (S.D.=10.84). The total scores of generic and disease-specific QOL were statistically significant, correlated with patients׳ total symptom severity scores and social support scores (all P values less than 0.01). Multiple regression analysis revealed that monthly household income and subjective social support were statistically significant predictors of generic and disease-specific QOL. Duration of hospitalization, support use degree, negative and general psychopathology symptoms were additional significant predictors of disease-specific QOL. This study suggests the importance of improving subjective social support in order to promote generic and disease-specific QOL. Controlling negative and general psychopathology symptoms and improving support use degree could additionally enhance the disease-specific QOL in patients with schizophrenia.

    Osteoporosis is a well recognized problem affecting millions of individuals worldwide. Consequently, the need to effectively, efficiently, and affordably diagnose and identify those at risk is essential; moreover, site-specific assessment of bone quality is necessary, not only in the process of risk assessment, but may also be desirable for other applications. The present study evaluated a new one-dimensional granular crystal sensor, composed of a tightly packed chain of beads under Hertzian contact interaction, representing the most suitable fundamental component for solitary wave generation and propagation. First, the sensitivity of the novel sensor was tested using densities of rigid polyurethane foam, representing clinical bone quality ranging from healthy, to severely osteoporotic. Once the relationship between the signal response and known densities was established, the sensor was used to measure several sites located in the proximal femur of ten human cadaveric specimens. The accuracy of the model was ...

    Phytochemicals in vegetables are important for human health, and their biosynthesis, metabolism and accumulation are affected by environmental factors. Light condition (light quality, light intensity and photoperiod) is one of the most important environmental variables in regulating vegetable growth, development and phytochemical accumulation, particularly for vegetables produced in controlled environments. With the development of light-emitting diode (LED) technology, the regulation of light environments has become increasingly feasible for the provision of ideal light quality, intensity and photoperiod for protected facilities. In this review, the effects of light quality regulation on phytochemical accumulation in vegetables produced in controlled environments are identified, highlighting the research progress and advantages of LED technology as a light environment regulation tool for modifying phytochemical accumulation in vegetables. © 2014 Society of Chemical Industry.

    Clinical learning is a vital component of nurse education and assessing student's experiences can provide useful insights for development. Whilst most research in this area has focused on the acute setting little attention has been given to all pre-registration nurses' experience across the clinical placements arenas. To examine of pre-registration nursing students (first, second and third year) assessment of their actual experiences of their most recent clinical learning clinical learning experience. A cross sectional survey involving a descriptive online anonymous questionnaire based on the clinical learning environment inventory tool. One higher education institution in the United Kingdom. Nursing students (n=147) enrolled in an undergraduate nursing degree. This questionnaire included demographic questions and the Clinical Learning Environment Inventory (CLEI) a 42 item tool measuring student's satisfaction with clinical placement. SPPS version 22 was employed to analyse data with descriptive and inferential statistics. Overall students were satisfied with their clinical learning experience across all placement areas. This was linked to the 6 constructs of the clinical learning environment inventory; personalization, innovation, individualization, task orientation, involvement, satisfaction. Significant differences in student experience were noted between age groups and student year but there was no difference noted between placement type, age and gender. Nursing students had a positive perception of their clinical learning experience, although there remains room for improvement. Enabling a greater understanding of students' perspective on the quality of clinical education is important for nursing education and future research. Copyright © 2017. Published by Elsevier Ltd.

    Full Text Available The ISO 9000 quality management system (QMS is a philosophy. It is a consistent and logical approach, which if implemented and practiced in day-to-day activities, with total support from senior management, can lead to doing things right, first time-every time. Many organisations adopt ISO 9000 system as a milestone in their quest for quality management programme. Effectiveness of a system depends on the attitude of employees who are responsible for its implementation. Therefore, it is essential to know the prevailing environment in an organisation. To measure the attitude of employees, a survey through a wel1-designed questionnaire can be used as an effective tool. The items of questionnaire are framed on the basis of requirements of QMS. Attitude of employees is measured on a five-point scale, for each answer. Agreement or disagreement (positive or negative directly measures the attitude of an employee on the said aspect Data analysis is carried out for establishing the validity of individual score to the total score of items across, using product moment correlation formula. Based on analysis of data, a comprehensive programme can be worked out for correcting the deficiencies observed through the attitude survey. This can also be used as a base for measuring the improvement of QMS in an organisation.

    Full Text Available Background: Poor nutritional status and worse health-related quality of life (QoL have been reported in haemodialysis (HD patients. The utilization of generic and disease specific QoL questionnaires in the same population may provide a better understanding of the significance of nutrition in QoL dimensions. Objective: To assess nutritional status by easy to use parameters and to evaluate the potential relationship with QoL measured by generic and disease specific questionnaires. Methods: Nutritional status was assessed by subjective global assessment adapted to renal patients (SGA, body mass index (BMI, nutritional intake and appetite. QoL was assessed by the generic EuroQoL and disease specific Kidney Disease Quality of Life-Short Form (KDQoL-SF questionnaires. Results: The study comprised 130 patients of both genders, mean age 62.7 ± 14.7 years. The prevalence of undernutrition ranged from 3.1% by BMI 25 also had worse scores in some QoL dimensions, but after adjustment the pattern was maintained only in the symptoms and problems dimension of KDQoL-SF (p = 0.011. Conclusion: Our study reveals that even in mildly undernourished HD patients, nutritional status has a significant impact in several QoL dimensions. The questionnaires used provided different, almost complementary perspectives, yet for daily practice EuroQoL is simpler. Assuring a good nutritional status, may positively influence QoL.

    Objective To examine associations among pathological motivations for exercise with eating disorder (ED) specific health-related quality of life (HRQOL). Method Survey data assessing ED severity (i.e., Eating Disorder Diagnostic Survey), ED specific HRQOL (i.e., Eating Disorders Quality of Life Instrument), and pathological motivations for exercise (i.e., Exercise Dependence Scale) were collected from female students (N = 387) at seven universities throughout the United States. Regression analyses were conducted to examine the associations among exercise dependence, ED-specific HRQOL and ED severity, and the interaction of exercise dependence and ED severity on HRQOL scores. Results The overall model examining the impact of ED severity and exercise dependence (independent variables) on HRQOL (dependent variable) was significant and explained 16.1% of the variance in HRQOL scores. Additionally, the main effects for ED severity and exercise dependence and the interaction among ED severity and exercise dependence were significant, suggesting that the combined effects of ED severity and exercise dependence significantly impacts HRQOL. Discussion Our results suggest that pathological motivations for exercise may exacerbate ED’s detrimental impact on HRQOL. Our results offer one possible insight into why exercise may be associated with deleterious effects on ED HRQOL. Future research is needed to elucidate the relationship among psychological aspects of exercise, ED, and HRQOL. PMID:24136170

    Full Text Available Heat stress limits the productivity of laying hens, as reflected by egg production and egg quality. The present study aimed at showing the correlations between egg quality parameters and environmental variables recorded on the day eggs were laid and on the previous days. Birds were housed in battery cages in a commercial poultry house. Main component analyses were used to verify associations between environmental and production variables, and Pearson's linear correlation tests were used to further investigate those associations. Analyses were carried out separately for to layer strains, Dekalb® White and Hy-Line® w36, and the variables egg weight (g, eggshell weight (g, specific gravity (g/cm³ and eggshell percentage (% were compared with the environmental variables of the same day of the production, and one, two, three, and four days before egg production. Sound intensity measured inside the houses was positively associated with the quality parameters of eggs produced on the next day. Thermal environmental variables affected the egg quality differently in each strain, particularly air temperature, internal roof tile temperature, relative humidity, and air velocity. Ammonia concentration measured inside the houses was lower than 1ppm, and did not affect production performance.

    We examined classrooms as complex systems that affect students’ literacy learning through interacting effects of content and amount of time individual students spent in literacy instruction along with the global quality of the classroom-learning environment. We observed 27 third grade classrooms serving 315 target students using two different observation systems. The first assessed instruction at a more micro-level; specifically, the amount of time individual students spent in literacy instruction defined by the type of instruction, role of the teacher, and content. The second assessed the quality of the classroom-learning environment at a more macro level focusing on classroom organization, teacher responsiveness, and support for vocabulary and language. Results revealed that both global quality of the classroom learning environment and time individual students spent in specific types of literacy instruction covering specific content interacted to predict students’ comprehension and vocabulary gains whereas neither system alone did. These findings support a dynamic systems model of how individual children learn in the context of classroom literacy instruction and the classroom-learning environment, which can help to improve observations systems, advance research, elevate teacher evaluation and professional development, and enhance student achievement.

    2014-03-01

    Full Text Available RNA-sequencing (RNA-seq is rapidly emerging as the technology of choice for whole-transcriptome studies. However, RNA-seq is not a bias free technique. It requires large amounts of RNA and library preparation can introduce multiple artifacts, compounded by problems from later stages in the process. Nevertheless, RNA-seq is increasingly used in multiple studies, including the characterization of tissue-specific transcriptomes from invertebrate models of human disease. The generation of samples in this context is complex, involving the establishment of mutant strains and the delicate contamination prone process of dissecting the target tissue. Moreover, in order achieve the required amount of RNA, multiple samples need to be pooled. Such datasets pose extra challenges due to the large variability that may occur between similar pools, mostly due to the presence of cells from surrounding tissues. Therefore, in addition to standard quality control of RNA-seq data, analytical procedures for control of 'biological quality’ are critical for successful comparison of gene expression profiles. In this study, the transcriptome of the central nervous system of a Drosophila transgenic strain with neuronal-specific RNAi of an ubiquitous gene was profiled using RNA-seq. After observing the existence of an unusual variance in our dataset, we showed that the expression profile of a small panel of marker genes, including GAL4 under control of a tissue specific driver, can identify libraries with low levels of contamination from neighboring tissues, enabling the selection of a robust dataset for differential expression analysis. We further analyzed the potential of profiling a complex tissue to identify cell-type specific changes in response to target gene down-regulation. Finally, we showed that trimming 5’ ends of reads decreases nucleotide frequency biases, increasing the coverage of protein coding genes and decreasing the occurrence of systematic technical

Methods The project applied a six-step multiphase development process with six distinct studies. (1 The elicitation of schizophrenic persons’ views on their quality of life was based on open-ended interviews with interviewees from different settings (acute ward inpatients, long-term care patients, community care patients; n = 268. (2 A cross-sectional study with schizophrenic and healthy persons was conducted to quantify the relative importance of the various aspect of quality of life that emerged from the qualitative study (n = 143. (3 We conducted an empirical comparison of response formats with schizophrenic persons (n = 32. (4 A scale construction- and reliability-testing study was performed (n = 203 as well as (5 a test-retest reliability study (n = 49. (6 The final questionnaire (QLiS, quality of life in schizophrenia was tested in an additional study on convergent and discriminant validity (n = 135. Results The QLiS comprises 52 items (plus 2 optional items related to work in 12 subscales: social contacts, appreciation by others, relationship to family, appraisal of pharmacotherapy, appraisal of psychopathological symptoms, cognitive functioning, abilities to manage daily living, appraisal of accommodation/housing, financial situation, leading a ’normal‘ life, confidence, general life-satisfaction. An item response format with four response categories was preferred by the schizophrenic persons. The mean values of the subscales clustered around the theoretical mean of the subscales and only minimal ceiling effects were found. The reliability (test-retest-reliability and internal consistency was with one exception > .70 for all subscales. Conclusion Taking the low

    Increased concern over the adverse health effects of air pollution has highlighted the need for air-pollution measurements, especially in urban areas, where many sources of air pollutants are normally monitored outdoors as part of obligations under the National Air Quality Strategies. Very little is known about air pollution indoors. In fact, the largest exposure to health-damaging indoor pollution probably occurs in the developing world, not in households, schools, and offices of developed countries where most research and control efforts have been focused to date. As a result much of the health impacts from air pollution worldwide seem to occur among the poorest and most vulnerable populations. The authors in their earlier studies have confirmed the importance of ambient air in determining the quality of air indoors. In this study an observation of air quality indoors and outdoors of domestic homes located in an urban environment from October 2004 to December 2005 in Agra, north central India, is performed. The purpose of this study was to characterize the indoor/outdoor (I/O) relationship of airborne pollutants and recognize their probable source in all three seasons, that is, winter, summer, and rainy season. Concentrations of SO(2), NO(2), CO(2), Cl(2), H(2)S, NH(3), RSPM, and PAH were monitored simultaneously and I/O ratios were calculated. In order to investigate the effect of seasonality on indoor and ambient air quality, winter to summer and winter to monsoon average ratios were calculated. It is apparent that there is a general pattern of increasing levels from monsoon to summer to winter, and similarly from outdoor to indoor air. Regressions analysis had been done to further investigate the influence of outdoor air-pollutant concentrations on indoor concentrations. The most probable categories of sources for these pollutants have been identified by using principal-component analysis. Indoor air pollution is a complex function of energy housing and

    Full Text Available This paper provides an approach to assessing Quality of Context (QoC parameters in a ubiquitous Ambient Assisted Living (AAL environment. Initially, the study presents a literature review on QoC, generating taxonomy. Then it introduces the context management architecture used. The proposal is verified with the Siafu simulator in an AAL scenario where the user’s health is monitored with information about blood pressure, heart rate and body temperature. Considering some parameters, the proposed QoC assessment allows verifying the extent to which the context information is up-to-date, valid, accurate, complete and significant. The implementation of this proposal might mean a big social impact and a technological innovation applied to AAL, at the disposal and support of a significant number of individuals such as elderly or sick people, and with a more precise technology.

    Children with optic pathway gliomas (OPGs) frequently experience vision loss from their tumors. Most pediatric OPG research has focused on radiographic and visual outcomes, yet the impact of vision loss on quality of life (QOL) in children with OPGs has not been studied. The present study prospectively recruited children ≤ 10 years of age with sporadic or neurofibromatosis type 1 (NF1)-related OPGs. Vision specific QOL was assessed by parent proxy using the Children's Visual Function Questionnaire (CVFQ), and scores were analyzed according to magnitude of visual acuity (VA) loss and presence of visual field (VF) loss. Thirty-six subjects completed the study (53 % female) with median age of 4.6 years. Children with mild, moderate and severe vision loss have lower CVFQ subscale scores, indicating a lower vision specific QOL, compared to those with normal vision. Lower Competence scores were noted in participants with more profound vision loss (p visually impaired eyes were rated as having greater difficulty with social interactions and pleasurable activities (Personality subscale, p = 0.039) compared to those with only one impaired eye. In summary, our findings demonstrate that children with vision loss secondary to their OPG have a decreased vision specific QOL compared to those with normal vision. Measuring vision specific QOL may be considered a meaningful secondary outcome measure for pediatric OPG clinical trials.

    To compare schizophrenia-specific quality of life measures, this study examined an 18-item Chinese version of 41-item Quality of Life Questionnaire in Schizophrenia (S-QoL; S-QoL-18-C) using 41 patients. The S-QoL-18-C was validated and compared with Schizophrenia Quality of Life Scale-Revision 4 (SQLS-R4). Index scores of S-QoL-18-C showed nearly identical psychometrics to S-QoL-C and S-QoL-18. No significant ceiling/floor effects were found, except with psychological and selfesteem subscales. Internal consistency was acceptable for whole scale and all subscales, except family relationships and sentimental life. Test-retest reliability was moderate to high (ICC=0.58-87). Score distributions and reliability of S-QoL-18-C were slightly lower than those of S-QoL-C. Convergent validity was supported by satisfactory correlations between subscales/index scores of S-QoL-18-C and similar scales (r=∣-0.35 ∣ to 0.80) and between corresponding subscales in S-QoL-18-C and S-QoL-C (r=0.85-0.97). S-QoL-18-C and SQLS-R4 demonstrated discriminant validity by differentiating among 30 patients with symptom remission, 30 patients without symptom remission, and 30 healthy individuals. Two patient groups were classified by criteria proposed by Remission in Schizophrenia Working Group. Three groups were controlled for five factors. Furthermore SQLS-R4, but not S-QoL-18-C, differentiated between patient groups with different hospitalization frequencies. Overall, S-QoL-18-C and SQLS-R4 show different advantages psychometrically.

    The mitigation of pollution released to the environment originating from the industrial sector has been the aim of all policy-makers and its importance is evident if the adverse health effects on the world population are considered. Although this concern is controversial, petroleum refinery has been linked to some adverse health effects for people living nearby. Apart from home, school is the most important indoor environment for children and there is increasing concern about the school environment and its impact on health, also in developing countries where the prevalence of pollution is higher. As most of the children spend more than 40% of their time in schools, it is critical to evaluate the pollution level in such environment. In the metropolitan region of Curitiba, South Brazil, five schools nearby industries and highways with high density traffic, were selected to characterize the aerosol and gaseous compounds indoor and outdoor of the classrooms, during 2009-2011. Size segregated aerosol samples were collected for analyses of bulk and single particle elemental profiles. They were analyzed by electron probe X-ray micro-analysis (EPXMA), and by energy-dispersive X-ray fluorescence (EDXRF), to investigate the elemental composition of individual particles and bulk samples. The concentrations of benzene, toluene, ethylbenzene, and xylene (BTEX); NO2; SO2; acetic acid; and formic acid were assessed indoor and outdoor using passive diffusion tubes. BTEX were analyzed by GC-MS and other collected gasses by ion chromatography. Individual exposition of BTEX was assessed by personal passive diffusion tubes. Results are interpreted separately and as a whole with the specific aim of identifying compounds that could affect the health of the scholars. In view of the chemical composition and size distribution of the aerosol particles, local deposition efficiencies in the children's respiratory systems were calculated, revealing the deposition of particles at extrathoracic

    Nursing work environments are key determinants of care quality. Our study aimed to evaluate the characteristics of nursing environments in primary care settings in the Canary Islands, and identify crucial components of such environments to improve quality. We conducted a cross-sectional study in primary care organisations using the Practice Environment Scale - Nursing Work Index tool. We collected sociodemographic variables, scores, and selected the essential items conducive to optimal care. Appropriate parametric and non-parametric statistical tests were used to analyse relations between variables (CI = 95%, error = 5%). One hundred and forty-four nurses participated. The mean total score was 81.6. The results for the five dimensions included in the Practice Environment Scale - Nursing Work Index ranged from 2.25 - 2.92 (Mean). Twelve key items for quality of care were selected; six were positive in the Canary Islands, two were mixed, and four negative. 7/12 items were included in Dimension 2 (fundamentals of nursing). Being a manager was statistically associated with higher scores (p<.000). Years of experience was inversely associated with scores in the 12 items (p<.021). Nursing work environments in primary care settings in the Canary Islands are comparable to others previously studied in Spain. Areas to improve were human resources and participation of nurses in management decisions. Nurse managers must be knowledgeable about their working environments so they can focus on improvements in key dimensions. Copyright © 2017 Elsevier España, S.L.U. All rights reserved.

    In the last 10 years, the use of ultrasound has expanded because of its portability, safety, real-time image display, and rapid data collection. Simultaneously, more people are going into the backcountry for enjoyment and employment. Increased deployment for the military and demand for remote medicine services have led to innovative use and study of ultrasound in extreme and austere environments. Ultrasound is effective to rapidly assess patients during triage and evacuation decision making. It is clinically useful for assessment of pneumothorax, pericardial effusion, blunt abdominal trauma, musculoskeletal trauma, high-altitude pulmonary edema, ocular injury, and obstetrics, whereas acute mountain sickness and stroke are perhaps still best evaluated on clinical grounds. Ultrasound performs well in the diverse environments of space, swamp, jungle, mountain, and desert. Although some training is necessary to capture and interpret images, real-time evaluation with video streaming is expected to get easier and cheaper as global communications improve. Although ultrasound is not useful in every situation, it can be a worthwhile tool in the austere or deployed environment.

    Full Text Available The present theoretical paper aims to develop a grounded model for designing instructional activities appropriate to e-learning and online learning environments. The suggested model is guided by learning principles of cognitivism, constructivism, and connectivism learning principles to help online learners constructing meaningful experiences and moving from knowledge acquisition to knowledge creation process. The proposed model consists of five dynamic and grounded domains that assure the quality of designing and using e-learning activities: Ø Social Domain; Ø Technological Domain; Ø Epistemological Domain; Ø Psychological domain; and Ø Pedagogical Domain. Each of these domains needs four types of presences to reflect the design and the application process of e-learning activities. These four presences are: Ø cognitive presence, Ø human presence, Ø psychological presence and Ø mental presence. Applying the proposed model (STEPP throughout all online and adaptive e-learning environments may improve the process of designing and developing e-learning activities to be used as mindtools for current and future learners.

    In this study, the characteristics, benefits, and effects of the environment and ecology project, which has been implemented in Turkey for the first time to restore the natural life that has been spoilt and the ecological balance of Lake Bafa located in Great Meander Basin, are searched. Moreover, the water samples taken from the stations that were spotted in the lake have been analyzed for the physical and chemical changes taking place in water quality before and after the project. The water cycle occurring as a result of giving water that was raised in Great Meander River by the Rubber regulator, which is the most important element of the project, through the Serçin inlet and feeder channel; and draining the saline and low-quality water to the river bed of the Great Meander, will improve the water quality, the natural life, and the ecological balance of the lake in time. Thanks to the water given to the lake within the scope of project, the salinity of the lake water decreased from 25,500 to 22,500 mmhos cm( - 1). The electrical conductivity, Na+, Mg+2, Ca+2, Cl(-), CO3(-2), HCO3(-), and the amount of the organic substances were found as over the appropriate values for fishery. Besides, the decreases in the amounts of NO3(-), HN3(-) and PO4(-3) affect the living beings in the lake negatively. In addition, the measures to take are specified, so that the natural life of the Lake and the ecological balance can renew themselves within a short time.

    Poor nutritional status and worse healthrelated quality of life (QoL) have been reported in haemodialysis (HD) patients. The utilization of generic and disease specific QoL questionnaires in the same population may provide a better understanding of the significance of nutrition in QoL dimensions. To assess nutritional status by easy to use parameters and to evaluate the potential relationship with QoL measured by generic and disease specific questionnaires. Nutritional status was assessed by subjective global assessment adapted to renal patients (SGA), body mass index (BMI), nutritional intake and appetite. QoL was assessed by the generic EuroQoL and disease specific Kidney Disease Quality of Life-Short Form (KDQoL-SF) questionnaires. The study comprised 130 patients of both genders, mean age 62.7 ± 14.7 years. The prevalence of undernutrition ranged from 3.1% by BMI ≤ 18.5 kg/m² to 75.4% for patients below energy and protein intake recommendations. With the exception of BMI classification, undernourished patients had worse scores in nearly all QoL dimensions (EuroQoL and KDQoL-SF), a pattern which was dominantly maintained when adjusted for demographics and disease-related variables. Overweight/ obese patients (BMI ≥ 25) also had worse scores in some QoL dimensions, but after adjustment the pattern was maintained only in the symptoms and problems dimension of KDQoL-SF (p = 0.011). Our study reveals that even in mildly undernourished HD patients, nutritional status has a significant impact in several QoL dimensions. The questionnaires used provided different, almost complementary perspectives, yet for daily practice EuroQoL is simpler. Assuring a good nutritional status, may positively influence QoL.

Skin cancer clinic of Jewish General Hospital in Montreal, Quebec, Canada. 56 patients with basal cell carcinoma and/or squamous cell carcinoma. Descriptive and inferential statistics applied to quantitative self-report data. Importance of appearance, psychological distress, and QOL. The most prevalent concerns included worries about tumor recurrence, as well as the potential size and conspicuousness of the scar. Skin cancer-specific QOL concerns significantly predicted distress manifested through anxious and depressive symptomology. In addition, the social concerns related to the disease were the most significant predictor of distress. The findings of this study provide healthcare professionals with a broad picture of the most prevalent NMSC-specific concerns, as well as the concerns that are of particular importance for different subgroups of patients. Nurses are in a position to provide pivotal psychosocial and informational support to patients, so they need to be aware of the often-overlooked psychosocial effects of NMSC to address these issues and provide optimal care.

    Free clinics provide free or reduced fee healthcare to individuals who lack access to primary care and are socio-economically disadvantaged. The purpose of this study is to examine health-related quality of life (HRQoL) among free clinic patients and its association with somatic symptoms, depression, and perceived neighborhood environment. Free clinic patients (n = 186) aged 18 years or older completed a self-administered survey. HRQoL, depression, somatic symptoms, and perceived neighborhood environment were measured using standardized instruments. Overall, the participants reported low level of HRQoL compared to the general healthy population. US born participants (n = 97) reported poorer psychological QoL and social relations, more somatic symptoms, and were more likely to be depressed than non-US born participants (n = 89). Higher numbers of somatic symptoms were associated with poorer environmental QoL. Depression was associated with all aspects of QoL; a higher level of depression was related to poorer QoL in all aspects. Our findings show that free clinic patients, especially US born patients, have poor HRQoL. Depression and perceived neighborhood satisfaction are key factors to determine HRQoL among free clinic patients. Mental health services and collaboration with other community organizations may help in improving HRQoL among free clinic patients. Finally, health promotion programs at the community level, not just at the clinic level, would be valuable to improve health of free clinic patients as perceived neighborhood environment is associated with their HRQoL.

    Mobility and resource-limitedness pose challenging issues to service configuration for quality of service (QoS) management in ubiquitous computing environments. Previous configuration approaches, such as static resource reservation,dynamic resource allocation and single service composition are not valid in the environments. In this study, we present an adaptive service configuration approach. Firstly, we reduce the dynamic configuration process to a control model which aims to achieve the variation of critical QoS on minimal level with less resource cost. Secondly, to deal with different QoS variations, we design two configuration strategies-service chain reconfiguration and QoS parameter adjustment-and implement them based on fuzzy logic control theory. Finally, a configuration algorithm is developed to flexibly employ the two configuration strategies in tune with the error of critical QoS in configuration process. The results of simulation experiments suggest that our approach outperforms existing configuration approaches in both QoS improvement and resource utilization.

    Fly species that are commonly recovered on human corpses concealed in houses or other dwellings are often dependent on human created environments and might have special features in their biology that allow them to colonize indoor cadavers. In this study we describe nine typical cases involving forensically relevant flies on human remains found indoors in southern Finland. Eggs, larvae and puparia were reared to adult stage and determined to species. Of the five species found the most common were Lucilia sericata Meigen, Calliphora vicina Robineau-Desvoidy and Protophormia terraenovae Robineau-Desvoidy. The flesh fly Sarcophaga caerulescens Zetterstedt is reported for the first time to colonize human cadavers inside houses and a COI gene sequence based DNA barcode is provided for it to help facilitate identification in the future. Fly biology, colonization speed and the significance of indoors forensic entomological evidence are discussed.

    Mwaniki, George R.

    Air pollution impacts occur at all scales, meaning that policies and air quality management practices must be implemented and coordinated at the local, regional, national, and global scales. This dissertation is part of a continuing effort to improve our understanding of various air quality related issues in different environments. The dissertation consists of four studies. In the first study, wintertime chemical composition of water-soluble particulate matter with aerodynamic diameter less than 2.5 microm (PM2.5) was monitored in the Treasure Valley region near Boise, Idaho. This study was aimed at understanding the major drivers of wintertime PM2.5 within the locality of Boise and its suburbs. From this study, organics and particulate nitrate were the dominant contributors to the PM2.5 mass during wintertime. In the second study, particle size distribution, light scattering coefficient, speciated water soluble PM2.5, and cloud condensation nuclei (CCN) concentration were monitored in a mixed deciduous forest in Northern Michigan during the Community Atmosphere-Biosphere Interactions Experiment (CABINEX-2009). The overall goal of this study was to understand on how emissions of biogenic volatile organic compounds (BVOC) affect the gas-phase and particle-phase chemistry in the near-canopy environment, and the implications on local and regional air quality. From this study aerosol derived from the oxidation of BVOCs exhibited reduced hygroscopicity and CCN activation potential compared to aerosols derived from anthropogenic activities. The third study employed the eddy covariance (EC) technique to understand source-sink interactions of carbon dioxide (CO2), methane (CH 4), carbon monoxide (CO) and nitrous oxide (N2O) in Xi'an, China. In this study urban vegetation were found to play a major role in regulating CO2 emissions within the city while vehicular activities were a major driver for CO and CH4 fluxes.

    A two-dimensional, depth-averaged hydrodynamic and water quality model was developed to better understand the circulation, mixing, and water quality processes taking place during riverine floodplain inundation and to aid in the design of effective ecosystem restoration plans. The model utilizes several computational methods designed to accurately compute flow and transport in the contrasting river channel and floodplain environments. Model performance was tested using benchmark simulations, and the model was then applied to a restored floodplain on the lower Cosumnes River, CA, USA to examine the distribution of hydraulic residence times and implications for phytoplankton exports to the downstream Sacramento-San Joaquin Delta. Average residence times were found to be highly spatially and temporally variable and correlated with observed phytoplankton concentrations. Results from hypothetical management scenarios indicated that if the floodplain were allowed to drain faster there would be no significant effect on phytoplankton exports. The model is currently being applied to assess the potential for floodplain remediation on the Upper Truckee River, CA to reduce loadings of nitrogen, phosphorus, and suspended sediment to Lake Tahoe, CA-NV, USA.

    Samples from eleven species of Lamiaceae were collected from different light environments in Venezuela for laboratory analysis. The studied species were: Plectranthus scutellarioides (Ps), Scutellaria purpurascens (Sp), Hyptis pectinata (Hp)), H. sinuata (Hs). Leonorus japonicus (Lj), Plecthranthus amboinicus (Pa) Ocimum hasilicum (Ocb), O. campechianum (Occ) Origanum majorana (Orm), Rosmarinus officinali, (Ro) and Salvia officinalis (So). Protein and soluble sugar contents per unit of area were measured, Specific Leaf Mass (SLM) and fresh:dry weight (FW/DW) ratios were calculated. The higher values for soluble sugars contents were present in sun species: Lj, Pa, Ocb, Occ, Orm, Ro and So; the lower values were obtained in low light species: Ps, Sp, Hp, Hs. The values of protein content do not show any clear trend or difference between sun and shade environments. The lowest values for the fresh weight: dry weight ratio are observed in sun species with the exception of Lj and Pa, while the highest value is observed in Pa, a succulent plant. The higher values of specific leaf mass (SLM) (Kg DMm(-2)) are observed in sun plants. The two way ANOVA revealed that there were significant differences among species and between sun and low light environments for sugar content and FW:DW ratio. while SLM was significant for environments but no significant for species, and not significant for protein for both species and environments. The soluble sugar content, FW:DW ratio and SLM values obtained in this work, show a clear separation between sun and shade plants. The sugar content and FW:DW ratio are distinctive within the species, and the light environment affected sugar content. FW:DW ratio and SLM. These species may he shade-tolerant and able to survive in sunny environments. Perhaps these species originated in shaded environments and have been adapting to sunny habitats.

Cross-sectional study, with retrospective data collection. Material and Methods. Homogenous groups of 68 persons (43 women aged 30.10 (25–39 years, with mild or moderate scoliosis, and 76 (38 women able-bodied persons, aged 30.11 (24–38 years, who 16.5 (12–26 years earlier had completed scoliosis-specific exercise or observation regimes, participated. Their respiratory characteristics did not differ from predicted values. The WHOQOL-BREF questionnaire, Oswestry Disability Questionnaire, and pain scale (VAS were applied. Results. The transformed WHOQOL-BREF scores ranged from 54.6 ± 11.19 in the physical domain in the mild scoliotic subgroup to 77.1 ± 16.05 in the social domain in the able-bodied subgroup. The ODQ values did not generally exceed 5.3 ± 7.53. Inter- and intragroup differences were nonsignificant. Age, marital status, education, and gender were significantly associated with the ODQ scores. Significant association between the ODQ and WHOQOL-BREF social relationships domain scores with the participation in exercise treatment was found. Conclusions. Participants with the history of exercise treatment generally did not differ significantly from their peers who were only under observation. This study cannot conclude that scoliosis-specific exercise treatment in adolescence alters quality of life in adulthood.

    The general purpose of this study was to determine whether the formation of DNA addition products ('adducts') in plants could be a valuable biomarker of genotoxic air pollution. Plants from several species were exposed to ambient atmosphere at urban and suburban sites representative of different environmental conditions. The levels of NO2 and of the quantitatively major genotoxic air pollutants benzene, toluene, and xylene were monitored in parallel with plant exposure. DNA adducts were measured in bean (Phaseolus vulgaris), rye-grass (Lolium perenne), and tobacco (Nicotiana tabacum) seedlings by means of the [32P]-postlabeling method. Whereas, no correlation was found between the levels of the major genotoxic air pollutants and the total amounts of DNA adducts, individual analyses revealed site-specific and plant species-specific adduct responses, both at the qualitative and quantitative level. Among these, the amount of a specific rye-grass DNA adduct (rgs1) correlated with benzene/toluene/xylene levels above a threshold. For further characterization, rye-grass seedlings were treated in controlled conditions with benzene, toluene, xylene or their derivatives. On the other hand, in vitro DNA adduct formation assays were developed involving benzene, toluene, xylene, or their derivatives, and plant microsomes or purified peroxidase. Although in some cases, these approaches produced specific adduct responses, they failed to generate the rgs1 DNA adduct, which appeared to be characteristic for on-site test-plant exposure. Our studies have thus identified an interesting candidate for further analysis of environmental biomarkers of genotoxicity.

    Wheat cultivars with wide introgression have strongly impacted global wheat production. Aegilops geniculata (MgUg) is an important wild relative with several useful traits that can be exploited for wheat improvement. Screening of Ae. geniculata addition lines indicated a negative effect of 1Ug and the positive effect of 1Mg chromosome on wheat dough strength. Negative effect of 1Ug is probably associated with variation in number and position of the tripeptide repeat motif in the high molecular weight glutenin (HMW-G) gene. To utilize the positive potential of 1Mg chromosome, three disomic substitution lines (DSLs) 1Mg(1A), 1Mg(1B) and 1Mg(1D) were created. These lines were characterized for morphological, cytogenetic properties and biochemical signatures using FISH, 1D-, 2D-PAGE and RP-HPLC. Contribution of wheat 1A, 1B and 1D chromosomes towards dough mixing and baking parameters, chapatti quality, Fe/Zn content and glume color were identified. Observed order of variation in the dough mixing and baking parameters {1Mg(1D) ≤wheat ≤1Mg(1B) ≤1Mg(1A)} indicated that chromosome specific introgression is desirable for best utilization of wild species’ potential.

    Specification-based subjective tests (SBSTs) form the basis for almost all performance analysis of image and video quality estimators (QEs). Our ability to compare the efficacy of different QEs across a wide range of applications depends on careful design of these SBST, so the conclusions that are drawn about how well a QE performs are reliable and accurate. In this paper, we explore methods to design biased SBSTs for image and video QEs. A biased SBST will produce an estimate of the performance of a given QE that is systematically different than its actual performance. We demonstrate by proof of concept that it's possible to create SBSTs that generate misleading or biased Pearson or Spearman correlation coefficients between subjective and objective scores, and we present some diagnostics that begin to evaluate when influential observations have been included in the SBST. Understanding how to create biased tests is a first step toward the overall goal of creating more effective unbiased SBSTs.

    The mitigation of pollution released to the environment originating from the industrial sector has been the aim of all policy-makers and its importance is evident if the adverse health effects on the world population are considered. Although this concern is controversial, petroleum refinery has been linked to some adverse health effects for people living nearby. Apart from home, school is the most important indoor environment for children and there is increasing concern about the school environment and its impact on health, also in developing countries where the prevalence of pollution is higher. As most of the children spend more than 40% of their time in schools, it is critical to evaluate the pollution level in such environment. In the metropolitan region of Curitiba, South Brazil, five schools nearby industries and highways with high density traffic, were selected to characterize the aerosol and gaseous compounds indoor and outdoor of the classrooms, during 2009–2011. Size segregated aerosol samples were collected for analyses of bulk and single particle elemental profiles. They were analyzed by electron probe X-ray micro-analysis (EPXMA), and by energy-dispersive X-ray fluorescence (EDXRF), to investigate the elemental composition of individual particles and bulk samples. The concentrations of benzene, toluene, ethylbenzene, and xylene (BTEX); NO{sub 2}; SO{sub 2}; acetic acid; and formic acid were assessed indoor and outdoor using passive diffusion tubes. BTEX were analyzed by GC–MS and other collected gasses by ion chromatography. Individual exposition of BTEX was assessed by personal passive diffusion tubes. Results are interpreted separately and as a whole with the specific aim of identifying compounds that could affect the health of the scholars. In view of the chemical composition and size distribution of the aerosol particles, local deposition efficiencies in the children's respiratory systems were calculated, revealing the deposition of

    Proposed quality specifications for glucose meters allow results to be in error by 5-10% or more of the "true" concentration. Because meters are used as aids in the adjustment of insulin doses, we aimed to characterize the quantitative effect of meter error on the ability to identify the insulin dose appropriate for the true glucose concentration. Using Monte Carlo simulation, we generated random "true" glucose values within defined intervals. These values were converted to "measured" glucose values using mathematical models of glucose meters having defined imprecision (CV) and bias. For each combination of bias and imprecision, 10,000-20,000 true and measured glucose concentrations were matched with the corresponding insulin doses specified by selected insulin-dosing regimens. Discrepancies in prescribed doses were counted and their frequencies plotted in relation to bias and imprecision. For meters with a total analytical error of 5%, dosage errors occurred in approximately 8-23% of insulin doses. At 10% total error, 16-45% of doses were in error. Large errors of insulin dose (two-step or greater) occurred >5% of the time when the CV and/or bias exceeded 10-15%. Total dosage error rates were affected only slightly by choices of sliding scale among insulin dosage rules or by the range of blood glucose. To provide the intended insulin dosage 95% of the time required that both the bias and the CV of the glucose meter be <1% or <2%, depending on mean glucose concentrations and the rules for insulin dosing. Glucose meters that meet current quality specifications allow a large fraction of administered insulin doses to differ from the intended doses. The effects of such dosage errors on blood glucose and on patient outcomes require study.

    There are few studies that evaluate dietary intakes and predictors of diet quality in older adults. The objectives of this study were to describe nutrient intakes and examine associations between demographic, economic, behavioral, social environment, and health status factors and diet quality. Cross-sectional data were from black, white, and Hispanic adults, age 60 to 99 years, living independently in New York City and participating in the Cardiovascular Health of Seniors and the Built Environment Study, 2009-2011 (n=1,306). Multivariable log-linear regression estimated associations between selected factors and good diet quality, defined as a Healthy Eating Index score more than 80 (based on the 2005 Dietary Guidelines for Americans [HEI-2005]). Dietary intakes were similar for men and women; intakes of energy, fiber, and the majority of micronutrients were less than recommendations, whereas intakes of fats, added sugar, and sodium were within the upper range or exceeded recommendations. Hispanic ethnicity (relative risk [RR]=1.37; 95% CI 1.07 to 1.75), energy intake <∼ 1,500 kcal/day (RR=1.93; 95% CI, 1.37 to 2.71), adherence to a special diet (RR=1.23; 95% CI: 1.02 to 1.50), purchasing food at supermarkets at least once/week (RR=1.34; 95% CI, 1.04 to 1.74), and being married/living with a partner (RR=1.37; 95% CI, 1.10 to 1.71) were positively associated with HEI-2005 score more than 80. Consuming at least one restaurant meal/day was negatively associated with HEI-2005 score more than 80 (RR=0.69; 95%CI, 0.50-0.94). These findings identify specific groups of older adults, such as blacks or those who live alone, who may benefit from dietary interventions, as well as specific modifiable behaviors among older adults, such as eating restaurant meals or shopping at supermarkets, which may be targeted through interventions.

    This study was conducted to generate genetic information in rice varieties based on a complete diallel crosses over two years. The results indicated that genotype effect was significant for all traits. Genotype × environment interaction effects were significant only for cooked grain length (CGL) and cooked grain shape (CGSH). General combining ability (GCA) and specific combining ability (SCA) effects were significant for entire traits, which indicated the important roles of both additive and non-additive gene actions. GCA x environment interaction effects were significant for CGL, CGSH and grain elongation index (GEI). In the controlling of the inheritance of milled grain shape (GSH), milled grain width (MGW), GEI, milled grain length (MGL), CGSH and cooked grain width (CGW), the additive gene effects were more important than non-additive one.The average degree of dominance was within the range of partial dominance for all of the traits. The narrow-sense heritability was ranged from 0.65 (GSH) to 0.36 (CGL). GCA effects were significant for all of the parents in milled grain length and it was significant for some of the parents in other traits. The crosses of Deilmani × IRFAON-215 exhibited significant SCA for GEI. The positive mean of heterosis was observed for CGW. The highest maximum values of heterosis were revealed in GEI, flowed by GSH, MGW and CGW. GCA and MPV were significantly and positively correlated together for all traits.

    2009-05-01

    We investigated the association between metabolic syndrome (MS) and health-related quality of life (HRQOL) assessed using generalised and obesity-specific QOL instruments. We recruited 456 outpatients [age: 19-81 years, body mass index (BMI): 16.3-36.7 kg/m2] in the primary care division from 12 general hospitals in Korea. HRQOL was measured using EuroQol comprising the health states descriptive system (EQ-5D) and visual analogue scale (EQ-VAS) as a general instrument. The Korean Obesity-related QOL scale (KOQOL) composed of six domains was used as a disease-specific QOL instrument. MS was defined on the basis of International Diabetes Federation (IDF) criteria with Korean-specific waist circumference cutoffs (men: 90 cm, women: 85 cm). Subjects with MS displayed significantly higher impairment of EQ-5D and KOQOL. Binary logistic regression analysis of MS patients with controls for age, gender, smoking, alcohol, exercise, education, income, marital status and medication history disclosed odds ratio (OR) values of 2.13 (1.33-3.41) for impaired total KOQOL, 2.07 (1.31-3.27) for impaired physical health, 1.63 (1.03-2.60) for impaired work-related health, 2.42 (1.45-4.04) for impaired routine life, 2.08 (1.27-3.40) for impaired sexual life and 2.56 (1.59-4.11) for diet distress. Among the EQ-5D dimensions, only pain/discomfort displayed a significantly increased OR of 1.60 (1.01-2.56) in MS group. Subjects with MS displayed a significantly impaired HRQOL compared with those without MS. MS and HRQOL were more strongly associated in obesity-specific QOL than in generalised QOL.

    Sediments have a significant influence on water quality, owing to their role both as a sink and a potential source of pollutants. In fluvial environments from mountainous catchments, the dynamics of sediment particles and particle-bound contaminants are still poorly understood. As stated by Symader et al. (2007), bottom sediments of small rivers in mountainous areas behave like a transport system of its own and show high temporal variation in their chemical composition. The transport of significant sedimentary loads, as suspended matter, in short periods of time, mainly in winter, poses some issues concerning monitoring and modelling approaches of the transport and fate of micro-pollutants at the catchment scale. On one hand, high stream-flow velocity peaks make it difficult or impossible to maintain suspended sediment samplers fixed in the river channel. On the other hand, the cycle of deposition and re-suspension of finer material, throughout the hydrological year, leads to temporal changes of sediment properties. Our contribution reports some results of an investigation on the water quality in a mountainous rural meso-scale catchment, located in the NE of Portugal. The study integrates the examination of metal contents in the sediments and the water body. The river-bottom sediments and water were simply collected in a planned sampling network, in two different periods of the hydrological year (high and low flow). The finer and most recently deposited sediment was preferentially sampled, and the Bierl R.; Kurtenbach, A.; Krein, A. (2007). Transport Indicators.

    The micro-structured double-layer target is an efficient method to improve proton quality. However, the laser absorption efficiency is low due to strong reflection at the front surface of such targets. Moreover, the proton charge is limited by the driving laser radius. To overcome these shortcomings, a specific double-layer (SDL) target with a vacuum gap in the center of the heavy ion layer is proposed in this paper. In this specified target, the laser reflection effect is significantly weakened and the absorption and penetration efficiencies are greatly enhanced. The high-energy electrons from Breakout afterburner regime efficiently transfer their energy to the protons. Both the energy of the spectral peaks and maximum proton energy are greatly increased. The periodic structure of the longitudinal electric field makes the force applied on the protons becomes homogeneous in time average and therefore reduce the energy spread. In these SDL targets, the proton layer radius and the accelerated proton charge are not limited by the laser radius. With a larger-radius proton layer, the protons can be accelerated to high energy with small energy spread. When the proton layer radius is reduced to the laser radius, the SDL target is still an effective structure to improve the proton quality. The mechanism is proved by a series of particle-in-cell simulations.

    The wide use of cosmetics and their perceived benefits upon well-being imply objective descriptions of their effects upon the different dimensions contributing to the quality of life (QoL). Such a goal pleas for using relevant and validated scientific instruments with robust measurement methods. This paper discusses the interest of the new validated questionnaire BeautyQoL specifically designed to assess the effect of cosmetic products on physical appearance and QoL. After conducting a review of skin appearance and QoL, three phases of the international codevelopment have been carried out in the following sequence: semi-directed interviews (Phase 1), acceptability study (Phase 2), and validation study (Phase 3). Data collection and validation process have been carried out in 16 languages. This review confirms that QoL instruments developed in dermatology are not suitable to assess cosmetic products, mainly because of their lack of sensitivity. General acceptability of BeautyQol was very good. Forty-two questions have been structured in five dimensions that explained 76.7% of the total variance: Social Life, Self-confidence, Mood, Vitality, and Attractiveness. Cronbach's alpha coefficients are between 0.932 and 0.978, confirming the good internal consistency of the results. The BeautyQol questionnaire is the first international instrument specific to cosmetic products and physical appearance that has been validated in 16 languages and could be used in a number of clinical trials and descriptive studies to demonstrate the added value of these products on the QoL.

    Full Text Available Abstract Background Responsiveness, or sensitivity to clinical change, is an important consideration in selection of a health-related quality of life (HRQL measure for trials or clinical applications. Many approaches can be used to assess responsiveness, which may affect the interpretation of study results. We compared the relative responsiveness of generic and heart failure specific HRQL instruments, as measured both by common psychometric indices and by external clinical criteria. Methods We analyzed data collected at baseline and 6-weeks in 298 subjects with heart failure on the following HRQL measures: EQ-5D (US, UK, and VAS Scoring, Kansas City Cardiomyopathy Questionnaire (KCCQ (Clinical and Overall Summary Score, and RAND12 (Physical and Mental Component Summaries. Three external indicators of clinical change were used to classify subjects as improved, deteriorated, or unchanged: 6-minute walk test, New York Heart Association (NYHA class, and physician global rating of change. Four responsiveness statistics (T-test, effect size, Guyatt's responsiveness statistic, and standardized response mean were used to evaluate the responsiveness of the select measures. The median rank of each HRQL measure across responsiveness indices and clinical criteria was then determined. Results Average age of subjects was 60 years, 75 percent were male, and had moderate to severe heart failure symptoms. Overall, the KCCQ Summary Scores had the highest relative ranking, irrespective of the responsiveness index or external criterion used. Importantly, we observed that the relative ranking of responsiveness of the generic measures (i.e. EQ-5D, RAND12 was influenced by both the responsive indices and external criterion used. Conclusion The disease specific KCCQ was the most responsive HRQL measure assessing change over a 6-week period, although generic measures provide information for which the KCCQ is not suitable. The responsiveness of generic HRQL measures may

    During the past decade, advances in survey and sensor technology have generated new opportunities to investigate the structure and dynamics of fluvial systems. Key geomatic technologies include the Global Positioning System (GPS), digital photogrammetry, LiDAR, and terrestrial laser scanning (TLS). The application of such has resulted in a profound increase in the dimensionality of topographic surveys - from cross-sections to distributed 3d point clouds and digital elevation models (DEMs). Each of these technologies have been used successfully to derive high quality DEMs of fluvial environments; however, they often require specialized and expensive equipment, such as a TLS or large format camera, bespoke platforms such as survey aircraft, and consequently make data acquisition prohibitively expensive or highly labour intensive, thus restricting the extent and frequency of surveys. Recently, advances in computer vision and image analysis have led to development of a novel photogrammetric approach that is fully automated and suitable for use with simple compact (non-metric) cameras. In this paper, we evaluate a new photogrammetric method, Structure-from-Motion (SfM), and demonstrate how this can be used to generate DEMs of comparable quality to airborne LiDAR, using consumer grade cameras at low costs. Using the SfM software PhotoScan (version 0.8.5), high quality DEMs were produced for a 1.6 km reach and a 3.3 km reach of the braided Ahuriri River, New Zealand. Photographs used for DEM creation were acquired from a helicopter flying at 600 m and 800 m above ground level using a consumer grade 10.1mega-pixel, non-metric digital camera, resulting in object space resolution imagery of 0.12 m and 0.16 m respectively. Point clouds for the two study reaches were generated using 147 and 224 photographs respectively, and were extracted automatically in an arbitrary coordinate system; RTK-GPS located ground control points (GCPs) were used to define a 3d non

    Patients with Addison's disease reproducibly self-report impairment in specific dimensions of general well-being questionnaires, suggesting particular deficiencies in health-related quality-of-life (HRQoL). We sought to develop an Addison's disease-specific questionnaire (AddiQoL) that could better quantify altered well-being and treatment effects. Design, Setting, Patients, Intervention, and Outcomes: We reviewed the literature to identify HRQoL issues in Addison's disease and interviewed patients and their partners in-depth to explore various symptom domains. A list of items was generated, and nine expert clinicians and five expert patients assessed the list for impact and clarity. A preliminary questionnaire was presented to 100 Addison's outpatients; the number of items was reduced after analysis of the distribution of the responses. The final questionnaire responses were assessed by Cronbach's alpha and Rasch analysis. Published studies of HRQoL in Addison's disease indicated reduced vitality and general health perception and limitations in physical and emotional functioning. In-depth interviews of 14 patients and seven partners emphasized the impact of the disease on the emotional domain. Seventy HRQoL items were generated; after the expert consultation process and pretesting in 100 patients, the number of items was reduced to 36. Eighty-six patients completed the final questionnaire; the responses showed high internal consistency with Cronbach's alpha 0.95 and Person Separation Index 0.94 (Rasch analysis). We envisage AddiQoL having utility in trials of hormone replacement and management of patients with Addison's disease, analogous to similar questionnaires in GH deficiency (AGHDA) and acromegaly (AcroQoL).

    The major component of a systematic review is assessment of the methodologic quality and bias of randomized and nonrandomized trials. While there are multiple instruments available to assess the methodologic quality and bias for randomized controlled trials (RCTs), there is a lack of extensively utilized instruments for observational studies, specifically for interventional pain management (IPM) techniques. Even Cochrane review criteria for randomized trials is considered not to be a "gold standard," but merely an indication of the current state of the art review methodology. Recently a specific instrument to assess the methodologic quality of randomized trials has been developed for interventional techniques. Our objective was to develop an IPM specific instrument to assess the methodological quality of nonrandomized trials or observational studies of interventional techniques. The item generation for the instrument was based on a definition of quality, to the extent to which the design and conduct of the trial were congruent with the objectives of the study. Applicability was defined as the extent to which procedures produced by the study could be applied using contemporary IPM techniques. Multiple items based on Cochrane review criteria and Interventional Pain Management Techniques - Quality Appraisal of Reliability and Risk of Bias Assessment for Nonrandomized Studies (IPM-QRBNR) were utilized. A total of 16 items were developed which formed the IPM-QRBNR tool. The assessment was performed in multiple stages. The final assessment was 4 nonrandomized studies. The inter-rater agreement was moderate to good for IPM-QRBNR criteria. Limited validity or accuracy assessment of the instrument and the large number of items to be scored were limitations. We have developed a new comprehensive instrument to assess the methodological quality of nonrandomized studies of interventional techniques. This instrument provides extensive information specific to interventional

    We explore the relationship between home-based triggers, asthma symptoms, and quality of life (QOL) with data from 177 adult and pediatric participants who received a home environmental assessment. Outcomes included the Asthma Quality of life Questionnaire, the Prediatric Asthma Quality of Life Questionnaire, the Paediatric Asthma Caregiver's Quality of Questionnaires and the Lara Asthma Symptom Scale. The absence of roaches and the use of dust mite covers were positively associated with QOL in pediatric and adult participants. Frequent bed sheet washing was associated with increased symptoms and decreased quality of life in adults and caregivers of pediatric participants. These findings confirm existing wisdom on roaches and dust mite covers and raise important questions about bed sheet washing recommendations.

    Image processing plays an important role in optimizing image quality and radiation dose in projection radiography. Unfortunately commercial algorithms are black boxes that are often left at or near vendor default settings rather than being optimized. We hypothesize that different commercial image-processing systems, when left at or near default settings, create significant differences in image quality. We further hypothesize that image-quality differences can be exploited to produce images of equivalent quality but lower radiation dose. We used a portable radiography system to acquire images on a neonatal chest phantom and recorded the entrance surface air kerma (ESAK). We applied two image-processing systems (Optima XR220amx, by GE Healthcare, Waukesha, WI; and MUSICA{sup 2} by Agfa HealthCare, Mortsel, Belgium) to the images. Seven observers (attending pediatric radiologists and radiology residents) independently assessed image quality using two methods: rating and matching. Image-quality ratings were independently assessed by each observer on a 10-point scale. Matching consisted of each observer matching GE-processed images and Agfa-processed images with equivalent image quality. A total of 210 rating tasks and 42 matching tasks were performed and effective dose was estimated. Median Agfa-processed image-quality ratings were higher than GE-processed ratings. Non-diagnostic ratings were seen over a wider range of doses for GE-processed images than for Agfa-processed images. During matching tasks, observers matched image quality between GE-processed images and Agfa-processed images acquired at a lower effective dose (11 ± 9 μSv; P < 0.0001). Image-processing methods significantly impact perceived image quality. These image-quality differences can be exploited to alter protocols and produce images of equivalent image quality but lower doses. Those purchasing projection radiography systems or third-party image-processing software should be aware that image

    Full Text Available The widespread use of cloud computing services is expected to deteriorate a Quality of Service andtoincrease the power consumption of ICT devices, since the distance to a server becomes longer thanbefore. Migration of virtual machines over a wide area can solve many problems such as load balancingand power saving in cloud computing environments.This paper proposes to dynamically apply WAN accelerator within the network when a virtual machine ismoved to a distant center, in order to prevent the degradation in performance after live migration ofvirtual machines over a wide area. mSCTP-based data transfer using different TCP connections beforeand after migration is proposed in order to use a currently available WAN accelerator. This paper doesnot consider the performance degradation of live migration itself. Then, this paper proposes to reduce thepower consumption of ICT devices, which consists of installing WAN accelerators as part of cloudresources actively and increasing the packet transfer rate of communication link temporarily. It isdemonstrated that the power consumption with WAN accelerator could be reduced to one-tenth of thatwithout WAN accelerator.

    Full Text Available Sleep is well known to have a significant impact on learning and memory. Specifically, studies adopting an experimentally induced sleep loss protocol in healthy individuals have provided evidence that the consolidation of spatial memories, as acquired through navigating and orienteering in spatial surroundings, is negatively affected by total sleep loss. Here, we used both objective and subjective measures to characterize individuals' quality of sleep, and grouped participants into either a poor (insomnia-like or normal (control sleep quality group. We asked participants to solve a wayfinding task in a virtual environment, and scored their performance by measuring the time spent to reach a target location and the number of wayfinding errors made while navigating. We found that participants with poor sleep quality were slower and more error-prone than controls in solving the task. These findings provide novel evidence that pre-existing sleep deficiencies in otherwise healthy individuals affects negatively the ability to learn novel routes, and suggest that sleep quality should be accounted for among healthy individuals performing experimental spatial orientation tasks in virtual environments.

    Full Text Available Many toxic substances in the workplace can modify human health and quality of life and there is still insufficient data on respiratory outcomes in adults exposed to phthalates. The aim of this work was to assess in waste management workers from the Nitra region of Slovakia (n = 30 the extent of exposure to phthalates and health-related outcomes. Four urinary phthalate metabolites mono(2-ethylhexyl phthalate (MEHP, monobutyl phthalate (MnBP, monoethyl phthalate (MEP and monoisononyl phthalate (MiNP were determined by high-performance liquid chromatography with mass spectrometry (HPLC-MS/MS. Urinary concentration of MEHP was positively associated with ratio of forced expiratory volume in 1 s to forced vital capacity % (FEV1/FVC (r = 0.431; p = 0.018 and MiNP with fat free mass index (FFMI (r = 0.439; p = 0.015. The strongest predictor of pulmonary function was the pack/year index as smoking history that predicted a decrease of pulmonary parameters, the FEV1/FVC, % of predicted values of peak expiratory flow (PEF % of PV and FEV1 % of PV. Unexpectedly, urinary MEHP and MINP were positively associated with pulmonary function expressed as PEF % of PV and FEV1/FVC. We hypothesize that occupational exposure to phthalates estimated from urinary metabolites (MEHP, MiNP can modify pulmonary function on top of lifestyle factors.

    Phenotypic traits that convey information about individual identity or quality are important in animal social interactions, and the degree to which such traits are influenced by environmental variation can have profound effects on the reliability of these cues. Using inbred genetic lines of the decorated cricket, Gryllodes sigillatus, we manipulated diet quality to test how the cuticular hydrocarbon (CHC) profiles of males and females respond across two different nutritional rearing environments. There were significant differences between lines in the CHC profiles of females, but the effect of diet was not quite statistically significant. There was no significant genotype-by-environment interaction (GEI), suggesting that environmental effects on phenotypic variation in female CHCs are independent of genotype. There was, however, a significant effect of GEI for males, with changes in both signal quantity and content, suggesting that environmental effects on phenotypic expression of male CHCs are dependent on genotype. The differential response of male and female CHC expression to variation in the nutritional environment suggests that these chemical cues may be under sex-specific selection for signal reliability. Female CHCs show the characteristics of reliable cues of identity: high genetic variability, low condition dependence and a high degree of genetic determination. This supports earlier work showing that female CHCs are used in self-recognition to identify previous mates and facilitate polyandry. In contrast, male CHCs show the characteristics of reliable cues of quality: condition dependence and a relatively higher degree of environmental determination. This suggests that male CHCs are likely to function as cues of underlying quality during mate choice and/or male dominance interactions.

  14. Of plasticity and specificity: dialectics of the micro- and macro-environment and the organ phenotype.

    The study of biological form and how it arises is the domain of the developmental biologists; but once the form is achieved, the organ poses a fascinating conundrum for all the life scientists: how are form and function maintained in adult organs throughout most of the life of the organism? That they do appears to contradict the inherently plastic nature of organogenesis during development. How do cells with the same genetic information arrive at, and maintain such different architectures and functions, and how do they keep remembering that they are different from each other? It is now clear that narratives based solely on genes and an irreversible regulatory dynamics cannot answer these questions satisfactorily, and the concept of microenvironmental signaling needs to be added to the equation. During development, cells rearrange and differentiate in response to diffusive morphogens, juxtacrine signals and the extracellular matrix (ECM). These components, which constitute the modular microenvironment, are sensitive to cues from other tissues and organs of the developing embryo as well as from the external macroenvironment. On the other hand, once the organ is formed, these modular constituents integrate and constrain the organ architecture, which ensures structural and functional homeostasis and therefore, organ specificity. We argue here that a corollary of the above is that once the organ architecture is compromised in adults by mutations or by changes in the microenvironment such as aging or inflammation, that organ becomes subjected to the developmental and embryonic circuits in search of a new identity. But since the microenvironment is no longer embryonic, the confusion leads to cancer: hence as we have argued, tumors become new evolutionary organs perhaps in search of an elusive homeostasis.

    Information on the relationship between domain-specific physical activity (PA) and health-related quality of life (HRQoL) in the general population and specific groups is still scarce. The aim of this study was to determine the relationship between PA in work, transport, domestic and leisure-time domains and HRQoL among university students. PA and HRQoL were assessed in a random stratified sample of 1750 university students using the International Physical Activity Questionnaire - long form and 12-item Short Form Health Survey, respectively. The Spearman's rank correlations, adjusted for age, community size, personal monthly budget, body mass index, smoking habits and alcohol intake ranged from -0.11 to 0.18 in female students and -0.29 to 0.19 in male students. Leisure-time, domestic, transport-related PA and total PA were positively related to HRQoL. Inverse correlations with HRQoL were only found for work-related PA in male students. Multiple linear regression analysis showed that only leisure-time PA was related to the Physical Summary Component score (β = 0.08 for females and β = 0.10 for males, P HRQoL, future studies should not only analyse total PA levels but also domain-specific PA levels. The evidence on the positive relationship of leisure-time, transport and domestic PA with HRQoL can potentially be used to support evidence-based promotion of PA in a university setting, and as a hypothesis for future longitudinal studies on such potential causal relationships.

    A model linking authentic leadership, structural empowerment, and supportive professional practice environments to nurses' perceptions of patient care quality and job satisfaction was tested. Positive work environment characteristics are important for nurses' perceptions of patient care quality and job satisfaction (significant factors for retention). Few studies have examined the mechanism by which these characteristics operate to influence perceptions of patient care quality or job satisfaction. A cross-sectional provincial survey of 723 Canadian nurses was used to test the hypothesized models using structural equation modeling. The model was an acceptable fit and all paths were significant. Authentic leadership had a positive effect on structural empowerment, which had a positive effect on perceived support for professional practice and a negative effect on nurses' perceptions that inadequate unit staffing prevented them from providing high-quality patient care. These workplace conditions predicted job satisfaction. Authentic leaders play an important role in creating empowering professional practice environments that foster high-quality care and job satisfaction.

  7. Are diagnosis specific outcome indicators based on administrative data useful in assessing quality of hospital care?

    Scott, I; Youlden, D; Coory, M

    2004-01-01

    Background: Hospital performance reports based on administrative data should distinguish differences in quality of care between hospitals from case mix related variation and random error effects. A study was undertaken to determine which of 12 diagnosis-outcome indicators measured across all hospitals in one state had significant risk adjusted systematic (or special cause) variation (SV) suggesting differences in quality of care. For those that did, we determined whether SV persists within hospital peer groups, whether indicator results correlate at the individual hospital level, and how many adverse outcomes would be avoided if all hospitals achieved indicator values equal to the best performing 20% of hospitals. Methods: All patients admitted during a 12 month period to 180 acute care hospitals in Queensland, Australia with heart failure (n = 5745), acute myocardial infarction (AMI) (n = 3427), or stroke (n = 2955) were entered into the study. Outcomes comprised in-hospital deaths, long hospital stays, and 30 day readmissions. Regression models produced standardised, risk adjusted diagnosis specific outcome event ratios for each hospital. Systematic and random variation in ratio distributions for each indicator were then apportioned using hierarchical statistical models. Results: Only five of 12 (42%) diagnosis-outcome indicators showed significant SV across all hospitals (long stays and same diagnosis readmissions for heart failure; in-hospital deaths and same diagnosis readmissions for AMI; and in-hospital deaths for stroke). Significant SV was only seen for two indicators within hospital peer groups (same diagnosis readmissions for heart failure in tertiary hospitals and inhospital mortality for AMI in community hospitals). Only two pairs of indicators showed significant correlation. If all hospitals emulated the best performers, at least 20% of AMI and stroke deaths, heart failure long stays, and heart failure and AMI readmissions could be avoided

    Contour propagation is an essential component of adaptive radiotherapy, but current contour propagation algorithms are not yet sufficiently accurate to be used without manual supervision. Manual review of propagated contours is time-consuming, making routine implementation of real-time adaptive radiotherapy unrealistic. Automated methods of monitoring the performance of contour propagation algorithms are therefore required. We have developed an automated workflow for patient-specific quality control of contour propagation and validated it on a cohort of head and neck patients, on which parotids were outlined by two observers. Two types of error were simulated—mislabelling of contours and introducing noise in the scans before propagation. The ability of the workflow to correctly predict the occurrence of errors was tested, taking both sets of observer contours as ground truth, using receiver operator characteristic analysis. The area under the curve was 0.90 and 0.85 for the observers, indicating good ability to predict the occurrence of errors. This tool could potentially be used to identify propagated contours that are likely to be incorrect, acting as a flag for manual review of these contours. This would make contour propagation more efficient, facilitating the routine implementation of adaptive radiotherapy.

    The organ-specific averaged specific absorption rate (SARosa ) in a heterogeneous human body phantom, the Virtual Family Boy, is determined for the first time in five realistic electromagnetic environments at the Global System for Mobile Communications downlink frequency of 950 MHz. We propose two methods based upon a fixed set of finite-difference time-domain (FDTD) simulations for generating cumulative distribution functions for the SARosa in a certain environment: an accurate vectorial cell-wise spline interpolation with an average error lower than 1.8%, and a faster scalar linear interpolation with a maximal average error of 14.3%. These errors are dependent on the angular steps chosen for the FDTD simulations. However, it is demonstrated that both methods provide the same shape of the cumulative distribution function for the studied organs in the considered environments. The SARosa depends on the considered organ and the environment. Two factors influencing the SARosa are investigated for the first time: conductivity over the density ratio of an organ, and the distance of the organ's center of gravity to the body's surface and exterior of the phantom. A non-linear regression with our model provides a correlation of 0.80. The SARosa due to single plane-wave exposure is also investigated; a worst-case single plane-wave exposure is determined for all studied organs and has been compared with realistic SARosa values. There is no fixed worst-case polarization for all organs, and a single plane-wave exposure condition that exceeds 91% of the SARosa values in a certain environment can always be found for the studied organs. © 2013 Wiley Periodicals, Inc.

    Full Text Available Lubricating oils, which are formulated with a number of chemicals blended base oils provide products that last longer, keep machinery cleaner and allow the machinery to work better under severe operating conditions. However, the used oil-waste generated by the automobiles and other allied industries poses an environmental hazard. The motivation of the present research study was to study the merits and demerits of commonly applicable technique acid/clay for reclamation of waste oil. This process has been employed for many years as the premier type of re-refining in which concentrated sulfuric acid is introduced to dehydrate waste lubricating oil. An acidic sludge is produced which is treated with clay. In this study, the conventional process of reclamation of waste oil, which is acid/clay, has been reviewed in the light of recovered product quality and hazardous effects on the environment and human health. Forty samples, in which, waste oil (10, reclaimed oil (30 were collected from different blending and reclamation plants located in different areas of the Punjab Province and were compared with two stroke blended oil (10 samples. The samples were tested for kinematic viscosity at 40 and 100ºC, Viscosity Index, Flash point, Sulfated Ash content, Copper Corrosion, Water content, Sediments and Color by following the standard ASTM Methods D-445, D-2270, D-92, D-482, D-130, D-95, D-473 and D-1500 (ASTM, 2002, respectively. According to the results, blended reclaimed (two stroke oil samples were found up to the recommended standard test limits. On the other hand, waste oil and reclaimed oil samples were found above the maximum test limits of acid number and copper corrosion and were found below in flash point test limit. Waste oil samples were highly contaminated and adulterated with mud and water. Although no such standard criteria or parameters are available for comparison but analysis results showed a bad reflection and due to which only few tests

    Perception plays a significant role on people's response to preventive measures. In the view of public awareness, the aim of this study was to explore factors that affect air quality perception and to reveal its potential patterns. Air quality perception of individuals, in terms of dust and overall air quality, was examined in relation to air pollutants concentrations, meteorological variables, personal characteristics as well as their thermal sensation and health condition. The data used were obtained from environmental measurements, in situ and from stations, and questionnaire surveys conducted in an outdoor urban Mediterranean area, Athens, Greece. The participants were asked to report their air quality perception and thermal sensation based on predefined scales. A thermal index, Physiological Equivalent Temperature (PET), was estimated to obtain an objective measure of thermal sensation. Particulate matter (PM10) and nitrogen oxide (NO) were associated with dust perception. Nitrogen oxides (NOx) and carbon monoxide (CO) were associated to air quality perception. Age, area of residence, health symptoms and thermal sensation also affected the perception of air quality. Dusty or poor air quality conditions were more likely to be reported when pollutants' concentrations were increased. Younger people, participants residing in the city center, experiencing health symptoms or warm thermal sensation showed a trend towards reporting more unfavorable air quality conditions.

    Pre-treatment patient specific quality assurance (QA) of advanced treatment techniques such as volumetric modulated arc therapy (VMAT) is one of important QA in radiotherapy. The fast and reliable dosimetric device is required. The objective of this study is to commission and validate the performance of COMPASS system for dose verification of VMAT technique. The COMPASS system is composed of an array of ionization detectors (MatriXX) mounted to the gantry using a custom holder and software for the analysis and visualization of QA results. We validated the COMPASS software for basic and advanced clinical application. For the basic clinical study, the simple open field in various field sizes were validated in homogeneous phantom. And the advanced clinical application, the fifteen prostate and fifteen nasopharyngeal cancers VMAT plans were chosen to study. The treatment plans were measured by the MatriXX. The doses and dose-volume histograms (DVHs) reconstructed from the fluence measurements were compared to the TPS calculated plans. And also, the doses and DVHs computed using collapsed cone convolution (CCC) Algorithm were compared with Eclipse TPS calculated plans using Analytical Anisotropic Algorithm (AAA) that according to dose specified in ICRU 83 for PTV.

    Peroxisomes are essential organelles that are characterized by the possession of enzymes that produce hydrogen peroxide (H2O2) as part of their normal catalytic cycle. During the metabolic process, peroxisomal proteins are inevitably damaged by H2O2 and the integrity of the peroxisomes is impaired. Here, we show that autophagy, an intracellular process for vacuolar degradation, selectively degrades dysfunctional peroxisomes. Marked accumulation of peroxisomes was observed in the leaves but not roots of autophagy-related (ATG)-knockout Arabidopsis thaliana mutants. The peroxisomes in leaf cells contained markedly increased levels of catalase in an insoluble and inactive aggregate form. The chemically inducible complementation system in ATG5-knockout Arabidopsis provided the evidence that these accumulated peroxisomes were delivered to vacuoles for degradation by autophagy. Interestingly, autophagosomal membrane structures specifically recognized the abnormal peroxisomes at the site of the aggregates. Thus, autophagy is essential for the quality control of peroxisomes in leaves and for proper plant development under natural growth conditions.

  20. Phylogenetic diversity and environment-specific distributions of glycosyl hydrolase family 10 xylanases in geographically distant soils.

    Full Text Available BACKGROUND: Xylan is one of the most abundant biopolymers on Earth. Its degradation is mediated primarily by microbial xylanase in nature. To explore the diversity and distribution patterns of xylanase genes in soils, samples of five soil types with different physicochemical characters were analyzed. METHODOLOGY/PRINCIPAL FINDINGS: Partial xylanase genes of glycoside hydrolase (GH family 10 were recovered following direct DNA extraction from soil, PCR amplification and cloning. Combined with our previous study, a total of 1084 gene fragments were obtained, representing 366 OTUs. More than half of the OTUs were novel (identities of <65% with known xylanases and had no close relatives based on phylogenetic analyses. Xylanase genes from all the soil environments were mainly distributed in Bacteroidetes, Proteobacteria, Acidobacteria, Firmicutes, Actinobacteria, Dictyoglomi and some fungi. Although identical sequences were found in several sites, habitat-specific patterns appeared to be important, and geochemical factors such as pH and oxygen content significantly influenced the compositions of xylan-degrading microbial communities. CONCLUSION/SIGNIFICANCE: These results provide insight into the GH 10 xylanases in various soil environments and reveal that xylan-degrading microbial communities are environment specific with diverse and abundant populations.

    Image processing plays an important role in optimizing image quality and radiation dose in projection radiography. Unfortunately commercial algorithms are black boxes that are often left at or near vendor default settings rather than being optimized. We hypothesize that different commercial image-processing systems, when left at or near default settings, create significant differences in image quality. We further hypothesize that image-quality differences can be exploited to produce images of equivalent quality but lower radiation dose. We used a portable radiography system to acquire images on a neonatal chest phantom and recorded the entrance surface air kerma (ESAK). We applied two image-processing systems (Optima XR220amx, by GE Healthcare, Waukesha, WI; and MUSICA(2) by Agfa HealthCare, Mortsel, Belgium) to the images. Seven observers (attending pediatric radiologists and radiology residents) independently assessed image quality using two methods: rating and matching. Image-quality ratings were independently assessed by each observer on a 10-point scale. Matching consisted of each observer matching GE-processed images and Agfa-processed images with equivalent image quality. A total of 210 rating tasks and 42 matching tasks were performed and effective dose was estimated. Median Agfa-processed image-quality ratings were higher than GE-processed ratings. Non-diagnostic ratings were seen over a wider range of doses for GE-processed images than for Agfa-processed images. During matching tasks, observers matched image quality between GE-processed images and Agfa-processed images acquired at a lower effective dose (11 ± 9 μSv; P < 0.0001). Image-processing methods significantly impact perceived image quality. These image-quality differences can be exploited to alter protocols and produce images of equivalent image quality but lower doses. Those purchasing projection radiography systems or third-party image-processing software should be aware that image

    Mobius3D and MobiusFX are model-based verification tools for treatment plan dose calculation and treatment delivery. The software facilitates patient-specific quality assurance by extracting data from linear accelerator treatment log files and performing a 3D dose calculation on the original patient CT dataset using an independent collapsed cone algorithm. In this study, we evaluate the ability of the Mobius system to detect linear accelerator-related errors compared with existing measurement-based systems, namely the ArcCHECK(®) and 3DVH(®) systems. Three original treatment plans and 47 plans with introduced delivery errors, for a total of 50 plan deliveries, were investigated. The results from this study demonstrated comparable gamma passing rates and error detectability between the Mobius and ArcCHECK(®) systems while the 3DVH system generally exhibited a lower sensitivity. This work also demonstrated the ability of the Mobius system to detect delivery errors of down to 2° collimator rotation, 1 mm MLC bank offset and 10 mm collimator jaw offset.

    Changes to the work environment prompted by the movement toward patient-centered care have the potential to improve occupational stress among health care workers by improving team-based work activities, collaboration, and employee-driven quality improvement. This study was conducted to examine professional quality of life among providers at patient-centered care pilot facilities. Surveys were conducted with 76 Veterans Affairs employees/providers at facilities piloting patient-centered care interventions, to assess demographics, workplace practices and views (team-based environment, employee voice, quality of communication, and turnover intention), and professional quality of life (compassion satisfaction, burnout, and secondary traumatic stress).Professional quality-of-life subscales were not related to employee position type, age, or gender. Employee voice measures were related to lower burnout and higher compassion satisfaction. In addition, employees who were considering leaving their position showed higher burnout and lower compassion satisfaction scores. None of the work practices showed relationships with secondary traumatic stress.

    Full Text Available Abstract Background The aim of the study was to develop a menopause-specific, preference-based health-related quality-of-life (HRQoL index reflecting both menopausal symptoms and potential side-effects of Hormone Replacement Therapy (HRT. Methods The study had three phases: the development of a health state classification, a prospective valuation survey and the estimation of a model to interpolate HRQoL indices for all remaining health states as defined by the classification. A menopausal health state classification was developed with seven dimensions: hot flushes, aching joints/muscles, anxious/frightened feelings, breast tenderness, bleeding, vaginal dryness and undesirable androgenic signs. Each dimension contains between three and five levels and defines a total of 6,075 health states. A sample of 96 health states was selected for the valuation survey. These states were valued by a sample of 229 women aged 45 to 60, randomly selected from 6 general practice lists in Sheffield, UK. Respondents were asked to complete a time trade-off (TTO task for nine health states, resulting in an average of 16.5 values for each health state. Results Mean health states valued range from 0.48 to 0.98 (where 1.0 is full health and zero is for states regarded as equivalent to death. Symptoms, as described by the classification system, can be rank-ordered in terms of their impact (from high to low on menopausal HRQoL as follows: aching joints and muscles, bleeding, breast tenderness, anxious or frightened feelings, vaginal dryness, androgenic signs. Hot flushes did not significantly contribute to model fit. The preferred model produced a mean absolute error of 0.053, but suffered from bias at both ends of the scale. Conclusion This article presents an attempt to directly value a condition specific health state classification. The overall fit was disappointing, but the results demonstrate that menopausal symptoms are perceived by patients to have a significant

    Volumetric-modulated arc therapy (VMAT) is now widely used clinically, as it is capable of delivering a highly conformal dose distribution in a short time interval. We retrospectively analyzed patient-specific quality assurance (QA) of VMAT and examined the relationships between the planning parameters and the QA results. A total of 118 clinical VMAT cases underwent pretreatment QA. All plans had 3-dimensional diode array measurements, and 69 also had ion chamber measurements. Dose distribution and isocenter point dose were evaluated by comparing the measurements and the treatment planning system (TPS) calculations. In addition, the relationship between QA results and several planning parameters, such as dose level, control points (CPs), monitor units (MUs), average field width, and average leaf travel, were also analyzed. For delivered dose distribution, a gamma analysis passing rate greater than 90% was obtained for all plans and greater than 95% for 100 of 118 plans with the 3%/3-mm criteria. The difference (mean ± standard deviation) between the point doses measured by the ion chamber and those calculated by TPS was 0.9% ± 2.0% for all plans. For all cancer sites, nasopharyngeal carcinoma and gastric cancer have the lowest and highest average passing rates, respectively. From multivariate linear regression analysis, the dose level (p = 0.001) and the average leaf travel (p < 0.001) showed negative correlations with the passing rate, and the average field width (p = 0.003) showed a positive correlation with the passing rate, all indicating a correlation between the passing rate and the plan complexity. No statistically significant correlation was found between MU or CP and the passing rate. Analysis of the results of dosimetric pretreatment measurements as a function of VMAT plan parameters can provide important information to guide the plan parameter setting and optimization in TPS.

    Full Text Available β-glucosidase is a crucial element of the microbial cellulose multienzyme complex since it is responsible for the regulation of the entire cellulose hydrolysis process. Therefore, the aim of the present work was to explore the diversity and distribution of glycosyl hydrolase family 1 β-glucosidase genes in three different environmental niches including, Himalayan soil, cow dung and compost by metagenomic approach. Preliminary evaluation through metabolic profiling using BIOLOG based utilization patterns of carbon, nitrogen, phosphorus and sulphur revealed the environment and substrate specific nature of the indigenous microbial population. Furthermore, clonal library selection, screening and sequence analysis revealed that most of the GH1 β-glucosidase proteins had low identities with the available database. Analysis of the distribution of GH1 β-glucosidase gene fragments and β-glucosidase producing microbial community revealed the environment specific nature. The OTUs obtained from Himalayan soil and compost metagenomic libraries were grouped into 19 different genera comprising 6 groups. The cow dung sample displayed the least diversity of GH1 β-glucosidase sequences, with only 14 genera, distributed among three groups- Bacteroidetes, Firmicutes and Actinobacteria. The metagenomic study coupled with metabolic profiling of GH1 β-glucosidase illustrated the existence of intricate relationship between the geochemical environmental factors and inherent microbial community.

    β-glucosidase is a crucial element of the microbial cellulose multienzyme complex since it is responsible for the regulation of the entire cellulose hydrolysis process. Therefore, the aim of the present work was to explore the diversity and distribution of glycosyl hydrolase family 1 β-glucosidase genes in three different environmental niches including, Himalayan soil, cow dung and compost by metagenomic approach. Preliminary evaluation through metabolic profiling using BIOLOG based utilization patterns of carbon, nitrogen, phosphorus and sulfur revealed the environment and substrate specific nature of the indigenous microbial population.

    Surface of Lithuania and surrounding countries is sculptured by five glaciations, which left behind morainic tills and melt water deposits, modified by erosion and later used for agriculture or overgrown by wild meadows or forests. The glaciations also left numerous erratic boulders and boulder fields that are declared as natural monuments in Lithuania and surrounding countries. Tens of single boulders and boulder fields are included into the Geosites database at the Lithuanian Geological Survey. Though sparse, but of high scientific value, Devonian, Permian, Triassic and Jurassic outcrops and quarries of Lithuania are variably protected. Quaternary scientists attempted to use single erratic boulders, their fields and abundances in tills to imply glacier dynamics. Some erratics came from known localities in Scandinavia and are called indicator boulders because they show the source and directions of ice sheet movements. Huge single boulders (e.g. 7 m long and 6 m high Puntukas, Anyksciai Regional Park) and wild boulder fields are natural monuments and attractive sites for visitors. Outcrops and quarries of Devonian dolomites and gypsium, Permian limestones and Jurassic sandstones widely used for a scientific research are parts of the protected geo-diversity in the Venta and Birzai regional parks, N and NW Lithuania. On the other hand, a large part of the c. 700 species of lichenized and allied fungi and of c. 500 bryophytes known in Lithuania are confined to natural or semi-natural (quarries) rocky habitats. Eight rock-dwelling lichen and nine bryophyte species are included in the Lithuanian Red Data Book, some of them are known from 1-2 localities or are thought to be extinct now. Besides, the recent investigations of dolomite quarries revealed them to be habitats for 7 bryophyte, 8 lichenized and lichenicolous species, previously unknown for Lithuania. One new lichenicolous species was discovered (Khodosovtsev et al., 2012). Some of the newfinds are rare or absent

    This study examines the psychometric properties of the Quality of Well Being Scale (QWB), the Positive and Negative Syndrome Scale (PANSS), the Heinrich-Carpenter Quality of Life Scale (QOLS), and the Lenert PANSS-based utility measure in a cohort of patients with schizophrenia and identifies threshold values of clinically meaningful change using the Clinical Global Impressions scale (CGI), as the anchor. The correlation of these measures at baseline and change at 6 and 12 months post enrollment in a comparative effectiveness trial was evaluated in 350 veterans with schizophrenia or schizoaffective disorder. An equipercentile method was used to estimate the minimum clinically important difference (MCID) for each measure. Effect size of 0.30-0.50 for baseline quality of life associated with inpatient status supported concurrent validity. The QWB was moderately correlated with disease-specific measures. The MCID as detected by the CGI at 6 months was 0.17 for QWB, 0.15 for the Lenert utility score, 1.13 for the QOLS, and 20.2 for the PANSS. These differences were stable at 12 months. The QWB is significantly correlated with disease specific measures of health related quality of life in schizophrenia. Published by Elsevier Ireland Ltd.

    Virtual Reality (VR) entered the mental health field some years ago. While the technology itself has been available for more than ten years now, there is still a certain amount of uncertainty among researchers and users as to whether VR will one day fulfill all it's promises. In this chapter we are giving an overview of the implementation of the technology in our mental health research facility in Basel, Switzerland. The development of two applications for use with claustrophobic and acrophobic patients perspectively serves just as an example within this context. Some may say, the chapter is too much based on technical considerations. Strictly speaking, VR is pure technology, even knowing that this special form of technology has sensory, psychological and even philosophical implications not known from other human computer interfaces so far. As far as we are concerned, the development of the technology for use within the mental health sector has merely just begun. As today's mostly used immersive output devices (Head-mounted Displays, shutter glasses) do not have a satisfactory resolution, do restrict movements and prevent multi-user-capabilities, there will be a soar of mental health applications the day some or at least the most important of these obstacles have been overcome.

    This study evaluated the feasibility of utilizing a 3D-printed anthropomorphic patient-specific head phantom for patient-specific quality assurance (QA) in intensity-modulated radiotherapy (IMRT). Contoured left and right head phantoms were converted from DICOM to STL format. Fused deposition modeling (FDM) was used to construct an anthropomorphic patient-specific head phantom with a 3D printer. An established QA technique and the patient-specific head phantom were used to compare the calculated and measured doses. When the established technique was used to compare the calculated and measured doses, the gamma passing rate for γ ≤ 1 was 97.28%, while the gamma failure rate for γ > 1 was 2.72%. When the 3D-printed patient-specific head phantom was used, the gamma passing rate for γ ≤ 1 was 95.97%, and the gamma failure rate for γ > 1 was 4.03%. The 3D printed patient-specific head phantom was concluded to be highly feasible for patient-specific QA prior to complicated radiotherapy procedures such as IMRT. PMID:28727787

    To assess the endocrine milieu in follicles of stimulated cycles comparing women with and without endometriosis. Steroids were measured in follicular fluid (FF) and in in vitro culture of granulosa-luteal cells, and this status was related to the quality of the embryos obtained after IVF. Case-control study. IVF program at the Instituto Valenciano de Infertilidad. Twenty-four women with laparoscopically documented endometriosis and 26 controls undergoing IVF. Individual follicular aspiration, oocyte isolation, FF storage, and preparation of luteinized granulosa cells for culture; oocyte insemination and embryo cleavage in standard IVF. Serum (day of ovum pickup) and FF measurements of estradiol, progesterone, testosterone, and androstenedione. Secretion of progesterone was measured in the cell-conditioned medium. Results were compared between patients with endometriosis and controls, as well as between oocytes that yielded embryos of different quality. Levels of progesterone in the FF increased with the severity of the disease, whereas testosterone accumulation in the FF decreased with the severity of the disease. An increase in progesterone accumulation in vitro was observed in basal and hCG-induced granulosa cell cultures. No difference was observed in terms of embryo quality, and no steroid marker was able to identify follicles with oocytes that displayed embryos of good or bad quality under the inverted microscope. The data show differences in the steroidogenesis of follicles from stimulated women with and without endometriosis. These changes indicate good endocrine health but are not predictive of embryo quality.

    Full Text Available Biological medical products nowadays are one of the most promising area at the pharmaceutical market. Biopharmaceutical market has significant benefits such as fast and effective development of production facilities, the development of more effective and safer medical products. The aim of our research was, on the example of medical products Cortexin and Retinalamin, examine the specifics of quality of biological medicinal products in the chain from production to sale. The objects of study - original biological medicines Cortexin and Retinalamin. Comparative, systematic, analytical methods and reviews were used. Biological medical products have fundamental differences from synthetic medicines, due to their source - alive cells which are usually used in their production process. Each production cycle results in a unique finished pharmaceutical products and minimal differences in the modes of production can significantly effect on the properties of biological medical products. Therefore, even if the physical, chemical and biological properties of the product thoroughly studied and described, it does not guarantee therapeutic equivalence of two biological products which are manufactured in different conditions. One of the most important issues today is the problem of maintaining properties and quality of biological medicines. These issues are actively resolving on the native pharmaceutical market: quality control system are developing and implementing in accordance with international standards in order to maintain maximum efficiency of biological medicines and to protect consumers from defective products. Biological products require special conditions of storage and transportation. In order to save physical, chemical and therapeutic properties, strict compliance with the relevant conditions of packaging, transport and intermediate storage, related to deviations in temperature during transportation and storage is needed.

    Organ-specific dose reduction significantly reduces the radiation exposure of radiosensitive organs. The purpose of this study was to assess the impact of a novel organ-specific dose reduction algorithm on image quality of pediatric chest CT. We included 28 children (mean age 10.9 ± 4.8 years, range 3-18 years) who had contrast-enhanced chest CT on a 128-row scanner. CT was performed at 100 kV using automated tube current modulation and a novel organ-specific dose-reduction algorithm (XCare trademark; Siemens, Forchheim, Germany). Seven children had a previous chest CT performed on a 64-row scanner at 100 kV without organ-specific dose reduction. Subjective image quality was assessed using a five-point scale (1-not diagnostic; 5-excellent). Contrast-to-noise ratio (CNR) and signal-to-noise ratio (SNR) were assessed in the descending aorta. Overall mean subjective image quality was 4.1 ± 0.6. In the subgroup of the seven children examined both with and without organ-specific dose reduction, subjective image quality was comparable (score 4.4 ± 0.5 with organ-specific dose reduction vs. 4.4 ± 0.7 without it; P > 0.05). There was no significant difference in mean signal-to-noise ratio and contrast-to-noise ratio with organ-specific dose reduction (38.3 ± 10.1 and 28.5 ± 8.7, respectively) and without the reduction (35.5 ± 8.5 and 26.5 ± 7.8, respectively) (P > 0.05). Volume computed tomography dose index (CTDI{sub vol}) and size-specific dose estimates did not differ significantly between acquisitions with the organ-specific dose reduction (1.7 ± 0.8 mGy) and without the reduction (1.7 ± 0.8 mGy) (P > 0.05). Organ-specific dose reduction does not have an impact on image quality of pediatric chest CT and can therefore be used in clinical practice to reduce radiation dose of radiosensitive organs such as breast and thyroid gland.

    A study of combining ability for improving rice cooking quality was carried out via genotype plus genotype × environment (GGE) biplot. Four restorer lines and three male sterile lines were used to obtain F1 in a line × tester trial at the Rice Research Institute, Amol, Iran in 2009. GGE biplot analysis showed that Neda and IR56 were the best general combiners for amylose content (AC), whereas Nemat and IR28 had the highest general combining ability (GCA) effects for gelatinization temperature (GT), and IR58 and IR59 showed the highest GCA effects in terms of gel consistency (GC). Meanwhile, IR58 and IR59 showed large specific combining ability (SCA) effects for AC, while Neda and SA13 had high SCA effects for GT. Nemat and IR28 had large SCA effects for GC. Because intermediate levels of AC, GT and GC are ideal, Nemat × IR59 was considered as the best possible cross. Based on these results, the GGE biplot showed good potential for identifying suitable parents, heterotic crosses and the best hybrids in line × tester data.

    Full Text Available The spatial distribution of stream water composition, as determined by the Geochemical Baseline Survey of the Environment (G-BASE conducted by the British Geological Survey (BGS can be successfully related under baseflow conditions to bedrock geochemistry. Further consideration of results in conjunction with site-specific monitoring data enables factors controlling both spatial and temporal variability in major element composition to be highlighted and allows the value of the survey to be enhanced. Hence, chemical data (i from streams located on Lower Silurian (Llandovery bedrock at 1 km2 resolution collected as part of the G-BASE survey of Wales and the West Midlands and (ii from catchment monitoring studies located in upland mid-Wales (conducted by Institute of Terrestrial Ecology, have been considered together as an example. Classification of the spatial survey data set in terms of potentially controlling factors was carried out so as to illustrate the level of explanation they could give in terms of observed spatial chemical variability. It was therefore hypothesised that on a geological lithostratigraphic series of limited geochemical contrast, altitude and land-use factors provide better explanation of this variability than others such as lithology at sampling site and stream order. At an individual site, temporal variability was also found to be of considerable significance and, at a monthly time-step, is explicable in terms of factors such as antecedent conditions and seasonality. Data suggest that the degree of this variability may show some relationship with stream order and land-use. Monitoring data from the region also reveal that relationships between stream chemistry and land-use may prove to be strong not only at base flow but also in storm flow conditions. In a wider context, predictions of the sensitivity of stream water to acidification based on classifications of soil and geology are successful on a regional scale. However

    Epigenetic modifications play crucial roles on establishment of tissue-specific transcription profiles and cellular characteristics. Direct conversions of fibroblasts into differentiated tissue cells by over-expression of critical transcription factors have been reported, but the epigenetic mechanisms underlying these conversions are still not fully understood. In addition, conversion of somatic cells into germ cells has not yet been achieved. To understand epigenetic mechanisms that underlie germ cell characteristics, we attempted to use defined epigenetic factors to directly convert mouse embryonic fibroblasts (MEFs) into germ cells. Here, we successfully induced germ cell-specific genes by inhibiting repressive epigenetic modifications via RNAi or small-molecule compounds. Under these conditions, some tissue-specific genes and stimulus-inducible genes were also induced. Meanwhile, the treatments did not result in genome-wide transcriptional activation. These results suggested that a permissive epigenetic environment resulted in selective de-repression of stimulus- and differentiation-inducible genes including germ cell-specific genes in MEFs.

    Patel, Ketan M; Lin, Chia-Yu; Cheng, Ming-Huei

    2015-07-01

    Microsurgical techniques for the treatment of lymphedema rapidly increased in popularity. Although surgical success with vascularized lymph node (VLN) transfer has been demonstrated, limited studies have investigated the influence of microsurgical treatments on health-related quality-of-life (HRQoL) parameters. The aim of this study was to prospectively evaluate changes in HRQoL following VLN transfer for upper- and lower-extremity lymphedema using a validated instrument. An Institutional Review Board-approved prospective study was performed of patients who underwent VLN transfer for symptomatic upper- or lower-limb lymphedema. A validated lymphedema-specific questionnaire-lymphoedema quality-of-life study-was utilized to assess specific quality-of-life parameters at multiple time points during the 12-month perioperative period. For a comparison with HRQoL metrics, limb circumference measurements were obtained to assess circumference differentiation. Twenty-five patients met the study criteria. Limb circumference analysis revealed significant early improvements following VLN transfer, with continued improvement during the study period (upper-limb lymphedema: 24.4 %; lower-limb lymphedema: 35.2 %).

  8. Plasticity regulators modulate specific root traits in discrete nitrogen environments.

    Directory of Open Access Journals (Sweden)

    Miriam L Gifford

    Full Text Available Plant development is remarkably plastic but how precisely can the plant customize its form to specific environments? When the plant adjusts its development to different environments, related traits can change in a coordinated fashion, such that two traits co-vary across many genotypes. Alternatively, traits can vary independently, such that a change in one trait has little predictive value for the change in a second trait. To characterize such "tunability" in developmental plasticity, we carried out a detailed phenotypic characterization of complex root traits among 96 accessions of the model Arabidopsis thaliana in two nitrogen environments. The results revealed a surprising level of independence in the control of traits to environment - a highly tunable form of plasticity. We mapped genetic architecture of plasticity using genome-wide association studies and further used gene expression analysis to narrow down gene candidates in mapped regions. Mutants in genes implicated by association and expression analysis showed precise defects in the predicted traits in the predicted environment, corroborating the independent control of plasticity traits. The overall results suggest that there is a pool of genetic variability in plants that controls traits in specific environments, with opportunity to tune crop plants to a given environment.

    The aim of this study was to assess symptomatic and quality of life outcome scores following site specific fascial reattachment surgery for pelvic organ prolapse using the validated Prolapse Quality of Life (P-QOL) questionnaires. One hundred and ninety two women underwent surgery for pelvic organ prolapse; ninety four underwent anterior repair (thirty four of them had vaginal hysterectomy), and ninety eight had posterior repair. Patients filled P-QOL questionnaires 24 hours prior to surgery and a postal P-QOL questionnaire six months post operatively. Pre and post operative questionnaires were paired. Quality of life and symptoms scores were calculated using Wilcoxon signed rank test. One hundred and one women returned their questionnaires and were suitable to include in the study. Forty nine underwent anterior repair (fifteen had vaginal hysterectomy) and 52 underwent posterior repair. Quality of life scores showed significant improvement in the anterior and posterior repair groups with the exception of general health in the anterior repair group and general health and prolapse impact in the posterior repair group. Anterior repair significantly improved urinary voiding and storage symptoms. Posterior repair group showed significant improvement in defecatory symptoms. Both groups showed improvement in sexual function and general prolapse symptoms. Prolapse repair with site specific fascial reattachment results in significant improvement in quality of life scores six months after surgery. Anterior repair improves urinary voiding and storage symptoms and posterior repair improves defecatory dysfunction and urinary voiding. Sexual function improves following prolapse repair with site specific fascial reattachment.

    2006-07-01

    Full Text Available Highly distributed environments such as pervasive computing environments not having global or broad control, need another attribute certificate management technique. For an efficient role based access control using attribute certificate, we use a technique of structuring role specification certificates. It can provide more flexible and secure collaborating environments. The roles are grouped and made them into the relation tree. It can reduce management cost and overhead incurred when changing the specification of the role. Further we use caching of frequently used role specification certificate for better performance in case applying the role. Tree structured role specification results secure and efficient role renewing and distribution. Caching of role specification helps an application of role. In order to be scalable distribution of the role specification certificate, we use multicasting packets. Also, performance enhancement of structuring role specification certificates is quantified in the sense of taking into account of the packet loss. In the experimental section, it is shown that role updating and distribution are secured and efficient.

  15. Predicting Essential Metabolic Genome Content of Niche-Specific Enterobacterial Human Pathogens during Simulation of Host Environments.

    Directory of Open Access Journals (Sweden)

    Tong Ding

    Full Text Available Microorganisms have evolved to occupy certain environmental niches, and the metabolic genes essential for growth in these locations are retained in the genomes. Many microorganisms inhabit niches located in the human body, sometimes causing disease, and may retain genes essential for growth in locations such as the bloodstream and urinary tract, or growth during intracellular invasion of the hosts' macrophage cells. Strains of Escherichia coli (E. coli and Salmonella spp. are thought to have evolved over 100 million years from a common ancestor, and now cause disease in specific niches within humans. Here we have used a genome scale metabolic model representing the pangenome of E. coli which contains all metabolic reactions encoded by genes from 16 E. coli genomes, and have simulated environmental conditions found in the human bloodstream, urinary tract, and macrophage to determine essential metabolic genes needed for growth in each location. We compared the predicted essential genes for three E. coli strains and one Salmonella strain that cause disease in each host environment, and determined that essential gene retention could be accurately predicted using this approach. This project demonstrated that simulating human body environments such as the bloodstream can successfully lead to accurate computational predictions of essential/important genes.

    2015-11-01

    Irritable Bowel Syndrome (IBS) is one of the most common gastrointestinal disorders particularly affecting the quality of life (QOL). Evaluating QOL in IBS patients is a valuable method of defining a psychobiological pattern of disease. Various disease specific and general instruments are now available to measure health-related QOL (HRQOL) in IBS patients. Though, no comparison has been made between these tools especially in non-western countries. We aimed to compare QOL measures between two specific and general QOL questionnaires in a sample of Iranian IBS patients. A total of 250 IBS patients were diagnosed based on Rome III criteria (mean age 29.6 ± 9.6 years). HRQOL was assessed using disease specific quality of life for IBS (IBS-QOL) and generic World Health Organization Quality of Life-BREF (WHOQOL-BREF) questionnaires. Patients also completed Speilberger`s "State/Trait Anxiety Inventory" and "Beck Depression Inventory-II" for the evaluation of anxiety and depression symptoms. The severity of symptoms was independently associated with HRQOL in patients using WHOQOL-BREF and IBS-QOL (r = -0.48 and -0.39 respectively, P WHOQOL-BREF questionnaires (standard β = 0.86 (95%CI: 1.15 - 1.44), P value WHOQOL-BREF is a psychometrically sound, rapid and convenient instrument whose HRQOL measure is as valid and accurate as the disease-specific IBS-QOL questionnaire. It seems reasonable to use the WHOQOL-BREF alongside the IBS-QOL.

    2012-01-01

    Full Text Available The study on the quality of life ( QoL in urban areas is gaining interest from a variety of disciplines such as planning, geography, sociology, economics, psychology, political science, marketing, and is becoming an important tool for urban planning and management. At present, there is a great deal of ambiguity and controversy on the concept of QoL, its elements and indicators. Thus, the present paper focuses on the development of a methodology for assessing quality of life in urban environment implementing a geographical informational system model that includes data from different areas of analysis, as follows: geographical data, Urban Audit socio-economic data, Urban Atlas data, satellite image data, survey data and indicators. The Geographic Information model derived from correlating the data mentioned above is used for evaluating the quality of life in Brăila, a 200,000 people city, situated in eastern Romania and port on the Danube River.

    Full Text Available Significant genotype vs. environment interaction (G x E is expected as a result of geographical diversity and differences in management techniques in melon growing. Ninety-six F3 families from the cross between inodorus and conomon melons were evaluated in three environments for studying interaction. The G x E interaction, genetic parameters, and direct and indirect gains were estimated. Average weight of the fruit, pulp thickness, cavity thickness, pulp firmness, and soluble solids were evaluated. The simple part of the G x E interaction was always greater than 99%, except for pulp firmness, where there was predominance of the complex part. The coefficient of genetic variation and genetic variance were overestimated by the G x E interaction. The direct gains from selection were higher than the indirect, except when selection was made by the mean of the three environments. Genotype assessments in more than one location are necessary, but selection should be made by the mean values of families in the environments.

    Green roofs are an increasingly important component of water sensitive urban design systems and can potentially improve the quality of urban runoff. However, there is evidence that they can occasionally act as a source rather than a sink for pollutants. In this study, the water quality of the outflow from both intensive and extensive green roof systems were studied in the city of Adelaide, South Australia over a period of nine months. The aim was to examine the effects of different green roof configurations on stormwater quality and to compare this with runoff from aluminium and asphalt roofs as control surfaces. The contaminant concentrations in runoff from both intensive and extensive green roofs generally decreased during the study period. A comparison between the two types of green roof showed that except for some events for EC, TDS and chloride, the values of the parameters such as pH, turbidity, nitrate, phosphate and potassium in intensive green roof outflows were higher than in the outflows from the extensive green roofs. These concentrations were compared to local, state, national and international water quality guidelines in order to investigate the potential for outflow runoff from green roofs to be reused for potable and non-potable purposes. The study found that green roof outflow can provide an alternative water source for non-potable purposes such as urban landscape irrigation and toilet flushing.

    Reaching and grasping parameters with and without haptic feedback were characterized in people with chronic post-stroke behaviors. Twelve (67 ± 10 years) individuals with chronic stroke and arm/hand paresis (Fugl-Meyer Assessment-Arm: ≥ 46/66 pts) participated. Three dimensional (3-D) temporal and spatial kinematics of reaching and grasping movements to three objects (can: cylindrical grasp; screwdriver: power grasp; pen: precision grasp) in a physical environment (PE) with and without additional haptic feedback and a 3-D virtual environment (VE) with haptic feedback were recorded. Participants reached, grasped and transported physical and virtual objects using similar movement strategies in all conditions. Reaches made in VE were less smooth and slower compared to the PE. Arm and trunk kinematics were similar in both environments and glove conditions. For grasping, stroke subjects preserved aperture scaling to object size but used wider hand apertures with longer delays between times to maximal reaching velocity and maximal grasping aperture. Wearing the glove decreased reaching velocity. Our results in a small group of subjects suggest that providing haptic information in the VE did not affect the validity of reaching and grasping movement. Small disparities in movement parameters between environments may be due to differences in perception of object distance in VE. Reach-to-grasp kinematics to smaller objects may be improved by better 3-D rendering. Comparable kinematics between environments and conditions is encouraging for the incorporation of high quality VEs in rehabilitation programs aimed at improving upper limb recovery.

    Patterned-ground and related periglacial features such as rock-glaciers and fractured-rock talus are emblematic of cold and dry arctic environments. The freeze-thaw processes that cause these features were first systematically investigated in the pioneering work of Linc Washburn. Unusual internal and autonomous micro-climatic and hydrologic processes of these features, however, are only beginning to be understood. Such features occur also in temperate latitude mountains, often in surprising abundance in regions such as the Great Basin (NV, USA) and San Juan Mtns (CO, USA), where they occur as active as well as relict (neoglacial or Pleistocene) features. Rock-dwelling species of pikas (Ochotona) in temperate North American and Asian mountains and in North American high-latitudes have long been known for their preference for talus habitats. We are investigating geomorphic, climatic, and hydrologic attributes of these periglacial features for their role in habitat quality and thermal environment of pikas. PRISM-modeled and observed climatic conditions from a range of talus types for Ochotona princeps in California and the western Great Basin (USA) indicate that, 1) thermal conditions of intra-talus-matrix in summer are significantly colder than talus-surface temperatures and colder than adjacent slopes and forefield wetlands where pika forage; 2) near-talus-surface locations (where haypiles are situated) are warmer in winter than intra-talus-matrix temperatures; 3) high-quality wetland vegetation in talus forefields is promoted by year-round persistence of outlet springs, seeps, and streams characteristic of active taluses. The importance of snowpack to winter thermal conditions is highlighted from these observations, suggesting a greater sensitivity of habitat in dry temperate regions such as eastern California and Nevada USA to warming winter minimum temperatures than in regions or elevations where snowpacks are more persistent. In regions where warming air

    2017-10-01

    The air quality in the subway metro indoor microenvironment has been of particular public concern. With specific reference to the growing demand of green transportation and sustainable development, subway metro systems have been rapidly developed worldwide in last decades. The number of metro commuters has continuously increased over recent years in metropolitan cities. In some cities, metro system has become the primary public transportation mode. Although commuters typically spend only 30-40min in metros, the air pollutants emitted from various interior components of metro system as well as air pollutants carried by ventilation supply air are significant sources of harmful air pollutants that could lead to unhealthy human exposure. Commuters' exposure to various air pollutants in metro carriages may cause perceivable health risk as reported by many environmental health studies. This review summarizes significant findings in the literature on air quality inside metro indoor environment, including pollutant concentration levels, chemical species, related sources and health risk assessment. More than 160 relevant studies performed across over 20 countries were carefully reviewed. These comprised more than 2000 individual measurement trips. Particulate matters, aromatic hydrocarbons, carbonyls and airborne bacteria have been identified as the primary air pollutants inside metro system. On this basis, future work could focus on investigating the chronic health risks of exposure to various air pollutants other than PM, and/or further developing advanced air purification unit to improve metro in-station air quality.

    Individual speech intelligibility was measured in quiet and noise for cochlear Implant recipients upgrading from the Freedom to the CP900 series sound processor. The postlingually deafened participants (n = 23) used either Nucleus CI24RE or CI512 cochlear implant, and currently wore a Freedom sound processor. A significant group mean improvement in speech intelligibility was found in quiet (Freiburg monosyllabic words at 50 dBSPL) and in noise (adaptive Oldenburger sentences in noise) for the two CP900 series SmartSound programs compared to the Freedom program. Further analysis was carried out on individual's speech intelligibility outcomes in quiet and in noise. Results showed a significant improvement or decrement for some recipients when upgrading to the new programs. To further increase speech intelligibility outcomes when upgrading, an enhanced upgrade procedure is proposed that includes additional testing with different signal-processing schemes. Implications of this research are that future automated scene analysis and switching technologies could provide additional performance improvements by introducing individualized scene-dependent settings.

    Objective Neurodegenerative diseases, such as dementia, have a profound impact on those with the conditions and their family carers. Consequently, the accurate measurement of family carers' quality of life (QOL) is important. Generic measures may miss key elements of the impact of these conditions, so using disease-specific instruments has been advocated. This systematic review aimed to identify and examine the psychometric properties of disease-specific outcome measures of QOL of family carers of people with neurodegenerative diseases (Alzheimer's disease and other dementias; Huntington's disease; Parkinson's disease; multiple sclerosis; and motor neuron disease). Design Systematic review. Methods Instruments were identified using 5 electronic databases (PubMed, PsycINFO, Web of Science, Scopus and the International Bibliography of the Social Sciences (IBSS)) and lateral search techniques. Only studies which reported the development and/or validation of a disease-specific measure for adult family carers, and which were written in English, were eligible for inclusion. The methodological quality of the included studies was evaluated using the COnsensus based Standards for the selection of health Measurement Instruments (COSMIN) checklist. The psychometric properties of each instrument were examined. Results 676 articles were identified. Following screening and lateral searches, a total of 8 articles were included; these reported 7 disease-specific carer QOL measures. Limited evidence was available for the psychometric properties of the 7 instruments. Psychometric analyses were mainly focused on internal consistency, reliability and construct validity. None of the measures assessed either criterion validity or responsiveness to change. Conclusions There are very few measures of carer QOL that are specific to particular neurodegenerative diseases. The findings of this review emphasise the importance of developing and validating psychometrically robust disease-specific

    Full Text Available Semen production data of Holstein-Friesian and Jersey bulls collected over a period of three years was analyzed to examine seasonal effects on quantity and quality of semen. Purebred breeding bulls of Holstein-Friesian and Jersey breeds (n = 18 for each breed, maintained under naturally ventilated open-sided sheds, were used for semen collection. Meteorological information on ambient temperature, relative humidity and rainfall was used to divide the calendar year into two stressful summer seasons viz; dry summer (April - June and wet summer (July–September and a stress free season (October - March. The number of ejaculates per bull recorded during three seasons were not significantly different (P>0.05 in both breeds. Friesian bulls produced lower ejaculatory volume during dry summer season, whereas Jersey bulls produced higher (P0.05 but in Jersey bulls it was lower during wet summer than other seasons. Wet summer resulted in reduced number of semen doses frozen per bull in both breeds. The results of this study indicated that wet summer season deteriorated semen quality in terms of mass motility, individual motility and number of doses in both breeds, except individual motility in semen of Friesian bulls.

    Stroke, one of the most prevalent geriatric diseases, is a leading cause of death worldwide that often results in permanent physical disability and decreased quality of life, and can have a negative impact on families both financially and emotionally. Although many previous studies have shown relationships between the risk of stroke and nutritional factors, clear dietary recommendations for the prevention and reduction of stroke recurrence have not been established. Several factors should be considered to control and manage stroke. For example, a considerable number of patients with stroke are poorly nourished, have several comorbidities and undesirable health-related behaviors may be present. Stroke patients are less likely to consume beneficial foods, have poorer eating habits and have impoverished dietary quality. In addition, psychological factors such as depression must also be considered in stroke management. Given these factors, dietary recommendations for stroke patients should be established. In this article, we summarized the nutritional status and dietary quality of stroke patients. We also suggested some nutritional guidelines for stroke patients and for those who are at risk for stroke.

    This is one of seven interlinked systematic reviews undertaken on behalf of the European Academy of Allergy and Clinical Immunology as part of their Guidelines for Food Allergy and Anaphylaxis, which focuses on instruments developed for IgE-mediated food allergy. Disease-specific questionnaires are significantly more sensitive than generic ones in measuring the response to interventions or future treatments, as well as estimating the general burden of food allergy. The aim of this systematic review was therefore to identify which disease-specific, validated instruments can be employed to enable assessment of the impact of, and investigations and interventions for, IgE-mediated food allergy on health-related quality of life (HRQL). Using a sensitive search strategy, we searched seven electronic bibliographic databases to identify disease-specific quality of life (QOL) tools relating to IgE-mediated food allergy. From the 17 eligible studies, we identified seven disease-specific HRQL instruments, which were then subjected to detailed quality appraisal. This revealed that these instruments have undergone formal development and validation processes, and have robust psychometric properties, and therefore provide a robust means of establishing the impact of food allergy on QOL. Suitable instruments are now available for use in children, adolescents, parents/caregivers, and adults. Further work must continue to develop a clinical minimal important difference for food allergy and for making these instruments available in a wider range of European languages.

    Full Text Available Plants growing in environments with different atmospheric conditions may present changes in the morphometric parameters of their leaves. Microgramma squamulosa (Kaulf. de la Sota is a neotropical epiphytic fern found in impacted environments. The aims of this study were to quantitatively compare structural characteristics of leaves in areas with different air quality conditions, and to identify morphometric parameters that are potential indicators of the effects of pollution on these plants. Fertile and sterile leaves growing on isolated trees were collected from an urban (Estância Velha and a rural (Novo Hamburgo environment, in Rio Grande do Sul, Brazil. For each leaf type, macroscopic and microscopic analyses were performed on 192 samples collected in each environment. The sterile and fertile leaves showed significantly greater thickness of the midrib and greater vascular bundle and leaf blade areas in the rural environment, which is characterized by less air pollution. The thickness of the hypodermis and the stomatal density of the fertile leaves were greater in the urban area, which is characterized by more air pollution. Based on the fact that significant changes were found in the parameters of both types of leaves, which could possibly be related to air pollutants, M. squamulosa may be a potential bioindicator.

    The Archaea domain is ubiquitously distributed and extremely diverse, however, environmental factors that shape archaeal community structure are not well known. Aquatic environments, including the water column and sediments harbor many new uncultured archaeal species from which metabolic and ecological roles remain elusive. Some environments are especially neglected in terms of archaeal diversity, as is the case of pristine tropical areas. Here we investigate the archaeal composition in marine and freshwater systems from Ilha Grande, a South Atlantic tropical environment. All sampled habitats showed high archaeal diversity. No OTUs were shared between freshwater, marine and mangrove sediment samples, yet these environments are interconnected and geographically close, indicating environment-specific community structuring. Group II Euryarchaeota was the main clade in marine samples, while the new putative phylum Thaumarchaeota and LDS/RCV Euryarchaeota dominated freshwaters. Group III Euryarchaeota, a rare clade, was also retrieved in reasonable abundance in marine samples. The archaeal community from mangrove sediments was composed mainly by members of mesophilic Crenarchaeota and by a distinct clade forming a sister-group to Crenarchaeota and Thaumarchaeota. Our results show strong environment-specific community structuring in tropical aquatic Archaea, as previously seen for Bacteria. PMID:24086729

    Full Text Available Abstract Background Antibodies are the main effectors against malaria blood-stage parasites. Evaluation of functional activities in immune sera from Phase 2a/b vaccine trials may provide invaluable information in the search for immune correlates of protection. However, the presence of anti-malarial-drugs, improper collection/storage conditions or concomitant immune responses against other pathogens can contribute to non-specific anti-parasite activities when the sera/plasma are tested in vitro. Purification of immunoglobulin is a standard approach for reducing such non-specific background activities, but the purification method itself can alter the quality and yield of recovered Ag-specific antibodies. Methods To address this concern, various immunoglobulin (Ig purification methods (protein G Sepharose, protein A/G Sepharose, polyethylene glycol and caprylic acid-ammonium sulphate precipitation were evaluated for their impact on the quality, quantity and functional activity of purified rabbit and human Igs. The recovered Igs were analysed for yield and purity by SDS-PAGE, for quality by Ag-specific ELISAs (determining changes in titer, avidity and isotype distribution and for functional activity by in vitro parasite growth inhibition assay (GIA. Results This comparison demonstrated that overall polyethylene glycol purification of human serum/plasma samples and protein G Sepharose purification of rabbit sera are optimal for recovering functional Ag-specific antibodies. Conclusion Consequently, critical consideration of the purification method is required to avoid selecting non-representative populations of recovered Ig, which could influence interpretations of vaccine efficacy, or affect the search for immune correlates of protection.

    Shapiro, S.; Lespérance, Y.; Levesque, H. J.

    The Cognitive Agents Specification Language (CASL) is a framework for specifying multiagent systems. It has a mix of declarative and procedural components to facilitate the specification and verification of complex multiagent systems. In this chapter, we describe CASL and a verification environment (CASLve) for it based on the PVS verification system. We give an example of a multiagent meeting scheduler application specified with CASL. To illustrate the verification system, we discuss a proof we carried out in it, namely, that all bounded-loop CASL specifications terminate.

    Full Text Available Food marketing for children is a major concern for public health nutrition and many schools make efforts to increase healthy eating. Food environments surrounding schools in urban areas may undermine these efforts for healthy nutrition within school programs. Our study aim is to describe the nutrition environment within walking distance of schools in terms of food quality and food marketing and to explore the degree to which elements of the nutrition environment varies by proximity to schools. In a cross-sectional study, we analyzed the surrounding food environments of a convenience sample of 46 target schools within 950m walking distance in 7 different urban districts across Vienna, Austria. In total, we analyzed data from 67 fast food outlets and 54 supermarkets analyzing a total of 43.129 packaged snack food and beverage products, from which 85% were for adults and 15% of the products were child-oriented. Proximity to the schools did not affect the availability of child-oriented products and dedicated food advertisements for children. After applying nutrient profiling using the Nutrient Profiling Model (NPM on child-oriented products, results showed that 15.8% of the packaged snack food were categorized as “healthy” foods and 84.2% as “less healthy”; for beverages 65.7% were categorized as “healthy” and 34.3% as “less healthy”. In conclusion, our results show that child-oriented snacks are not more frequently advertised around schools but substantially lack in nutritional quality with the potential to undermine efforts for promoting healthy eating practices within schools.

  9. From field barley to malt: detection and specification of microbial activity for quality aspects.

    Science.gov (United States)

    1999-01-01

    Barley grain carries a numerous, variable, and complex microbial population that mainly consists of bacteria, yeasts, and filamentous fungi and that can partly be detected and quantified using plating methods and microscopic and molecular techniques. The extent and the activity of this microflora are determined by the altering state of the grain and the environmental conditions in the malt production chain. Three ecological systems can be distinguished: the growing cereal in the field, the dry barley grain under storage, and the germinating barley kernel during actual malting. Microorganisms interact with the malting process both by their presence and by their metabolic activity. In this respect, interference with the oxygen uptake by the barley grain and secretion of enzymes, hormones, toxins, and acids that may affect the plant physiological processes have been studied. As a result of the interaction, microorganisms can cause important losses and influence malt quality as measured by brewhouse performance and beer quality. Of particular concern is the occurrence of mycotoxins that may affect the safety of malt. The development of the microflora during malt production can to a certain extent be controlled by the selection of appropriate process conditions. Physical and chemical treatments to inactivate the microbial population on the barley grain are suggested. Recent developments, however, aim to control the microbial activity during malt production by promoting the growth of desirable microbial cultures, selected either as biocontrol agents inhibiting mycotoxin-producing molds or as starter cultures actively contributing to malt modification. Such techniques may offer natural opportunities to improve the quality and safety of malt.

    Childhood illness or disability can affect the quality of life (QoL) of the child's primary caregiver. Our aim was to identify, describe the content and systematically review the psychometric properties of condition-specific QoL questionnaires for caregivers of children. Medline, PsycInfo, Embase, CINAHL, and the Cochrane library databases were searched from 1 January 1990 to 30 June 2011. Articles related to the development and measurement of caregiver QoL were screened to identify condition-specific questionnaires. The characteristics of the questionnaires were extracted, and their psychometric properties were evaluated using the consensus-based standards for the selection of health measurement instruments checklist with 4-point scale. We identified 25 condition-specific caregiver QoL questionnaires covering 16 conditions. Conditions included atopic dermatitis, asthma, diabetes, oro-facial disorders, and two acute illnesses. Questionnaires were developed predominantly in high-income countries. Questionnaires had the highest quality rating for content validity, followed by hypothesis testing. Methodological quality was satisfactory for criterion validity; fair in reliability and responsiveness; and poor in internal consistency and structural validity. The increasing number of questionnaires developed over time shows improved recognition of the importance of caregiver QoL. There is a paucity of QoL questionnaires for caregivers of otherwise healthy children suffering from physical injuries and acute conditions associated with significant caregiver burden. Cultural validation of existing and new questionnaires in lower-income countries is necessary. Data collected by condition-specific questionnaires can assist clinicians and health economists in estimating caregiver burden and the types of healthcare services caregivers require and may be useful for healthcare administrators to evaluate interventions.

    Full Text Available Purpose: to conduct researches of influence of classes of the sportswomen who are going in for bodybuilding and fitness-bikini on manifestation of physical qualities in different phases of the ovarian-menstrual cycle. Material & Methods: researches were conducted in sports fitness-clubs of Kharkov "Feromon", "Gorod", “King” with the qualified sportswomen who are going in for bodybuilding and fitness-bikini within 3 months of the preparatory period in number of 14 people. We used as methods of the research: the analysis of references and testing of level of motive qualities in separate phases of OMC. Results: the theoretical analysis of features of the accounting of phases of OMC at sportswomen is submitted and the testing of the level of development of physical qualities in different phases of the specific biological cycle at the qualified sportswomen, who are going in for bodybuilding, is held. Conclusions: the received results demonstrate that physical efficiency of the qualified sportswomen, who are going in for bodybuilding, is not identical in phases of the ovarian-menstrual cycle. It is revealed that the best conditions for performance of considerable exercise stresses in post-ovulatory and post-menstrual phases of OMC, therefore it is expedient to plan them in the preparatory periods of the qualified sportswomen, who are going in for bodybuilding.

    The main goal of therapy for Graves' orbitopathy (GO) is to restore visual function and to improve quality of life (QOL); therefore, the idea of self-assessment of eye changes by the patient has been developed. We developed a validated Polish version of the GO-QOL questionnaire (GO-QOLpl). As an original version we used the English version of GO-QOL, which consists of 15 questions summarised in two subscales. GO-QOLpl was translated and validated in accordance with standard principles for translation of patient-reported outcomes (PRO). GO-QOLpl is a linguistically validated version of the original GO-QOL questionnaire, which is recommended by the European Group of Graves' Orbitopathy (EUGOGO). We strongly support the use of GO-QOLpl for the assessment of QOL among Polish patients with GO in clinical practice.

    Full Text Available Background: Though the fight against malaria continued to be on the increased, the disease still remains a major public health problem in many developing countries, especially in the rural areas. The extent of drug use and its effect is affected among other things by the pattern in which these drugs are prescribed by the health workers. Patients′ assessment of the quality of care depends on their ability to judge whether health care providers are adhering to the defined standard of care, hence it is necessary to assess the views of patients regarding the quality of care they received from the primary health care (PHC centers. Aim: This study aimed at evaluating consumer′s perception of the quality of malaria treatment in PHC centers of Jos and environs. Materials and Methods: Nine PHC centers were selected by multi-stage random sampling, five from Jos North and four from Jos South Local Government Areas of Plateau State. Patients of both sexes within the age range of 18 years and above who visited the PHC centers for malaria treatment were considered eligible to participate in the survey, provided that they were able to understand and respond to the interview questions. A semi-structured interviewer questionnaire which was adapted from previous health survey studies was administered to all the 249 eligible participants. The data collected were analyzed using the Statistical Package for Social Sciences (SPSS version 20.0 software programmer. Results: The result showed that there were no consistently significant differences (P > 0.05 regarding patient satisfaction between male and female patients across selected items in the various domains, that is, irrespective of respondents′ sex, their perception of the quality of health services rendered by PHCs was similar. Conclusion: It was therefore concluded that there was similar satisfaction level between the male and the female, though some key health services were not readily available in the

    Full Text Available Irritable Bowel Syndrome (IBS is one of the most common gastrointestinal disorders particularly affecting the quality of life (QOL. Evaluating QOL in IBS patients is a valuable method of defining a psychobiological pattern of disease. Various disease specific and general instruments are now available to measure health-related QOL (HRQOL in IBS patients. Though, no comparison has been made between these tools especially in non-western countries. We aimed to compare QOL measures between two specific and general QOL questionnaires in a sample of Iranian IBS patients. A total of 250 IBS patients were diagnosed based on Rome III criteria (mean age 29.6 ± 9.6 years. HRQOL was assessed using disease specific quality of life for IBS (IBS-QOL and generic World Health Organization Quality of Life-BREF (WHOQOL-BREF questionnaires. Patients also completed Speilberger`s “State/Trait Anxiety Inventory” and “Beck Depression Inventory-II” for the evaluation of anxiety and depression symptoms. The severity of symptoms was independently associated with HRQOL in patients using WHOQOL-BREF and IBS-QOL (r = -0.48 and -0.39 respectively, P P value < 0.001. Controlling for anxiety and depression symptoms did not influence the strength of observed correlation. The WHOQOL-BREF is a psychometrically sound, rapid and convenient instrument whose HRQOL measure is as valid and accurate as the disease-specific IBS-QOL questionnaire. It seems reasonable to use the WHOQOL-BREF alongside the IBS-QOL.

    Post-translational modifications (PTMs) play an important role in life science. The most widely studied protein modifications in biological science include protein phosphorylation, acylation, glycosylation, ubiquitination, acetylation, oxidation, methylation and so on. This review outlines current achievements in the study of protein modifications in muscle food using proteomic approaches. First we describe the general knowledge of protein modifications and then the development of proteomic approaches for the characterization of such modifications. Second, we describe the effects of protein modifications on muscle foods and devote our main attention to the application of proteomic approaches for the analysis of these modifications. We conclude that proteomics analysis is powerful for the study of protein modifications and analysis of meat quality characteristics in the process of food production.

    2014-07-01

    Diseases caused by impaired regulation of energy balance, in particular obesity, represent a major global health burden. Although polymorphisms, lifestyle and dietary choices have been associated with differential risk of obesity and related conditions, a substantial proportion of the variation in disease risk remains unexplained. Evidence from epidemiological studies, natural experiments and from studies in animal models has shown that a poor intra-uterine environment is associated causally with increased risk of obesity and metabolic disease in adulthood. Induction of phenotypes that increase disease risk involves the fetus receiving cues from the mother about the environment which, via developmental plasticity, modify the phenotype of the offspring to match her environment. However, inaccurate information may induce an offspring phenotype that is mismatched to the future environment. Such mismatch has been suggested to underlie increased risk of metabolic disease associated with a poor early life environment. Recent studies have shown that induction of modified phenotypes in the offspring involves altered epigenetic regulation of specific genes. Identification of a central role of epigenetics in the aetiology of obesity and metabolic disease may facilitate the development of novel therapeutic interventions and of biomarkers of disease risk.

    Full Text Available Vocational Education and Training for Tourism. Specific Aspects which Influence the Students’ Perception of the Quality of Their Learning Experience. Quality in education has been defined in various ways, each definition representing a different approach. Karl Popper defines human rationality by the adequacy of one’s action to a specific situation. Furthermore, the French sociologist Pierre Bourdieu argues that the actions that people undertake are based on their previous life experiences and on their social and professional status. Vocational Education and Training (VET addresses young people and adults whose social status can influence their level of satisfaction with the quality of the educational process. The present article seeks to present the results of a questionnaire-based survey applied to the students who have attended the travel agent and tourism manager courses at the Centre for Tourism Training of the Babeş-Bolyai University, Cluj-Napoca. The data illustrate the strong influence of the variable age and previous educational experience on the subjects' satisfaction regarding some aspects of the training activities.

    The volume of CT examinations has increased with resultant increases in collective dose values over the last decade. To analyze the impact of the tube current and voltage modulation for dose values and image quality of pediatric head CT examinations. Head CT examinations were performed on anthropomorphic phantoms and four pediatric age categories before and after the introduction of dedicated pediatric curves for tube voltage and current modulation. Local diagnostic reference levels were calculated. Visual grading characteristic image quality evaluation was performed by four pediatric neuroradiologists and image noise comparisons were performed. Pediatric-specific modulation curves demonstrated a 49% decrease in mean radiation dose for phantom examinations. The local diagnostic reference levels (CTDIvol) for clinical examinations decreased by 52%, 41%, 46% and 40% for newborn, 5-, 10- and 15-year-old patients, respectively. Visual grading characteristic image quality was maintained for the majority of age categorizations (area under the curve = 0.5) and image noise measurements did not change (P = 0.693). Pediatric-specific dose modulation curves resulted in an overall mean dose reduction of 45% with no significant differences in subjective or objective image quality findings. (orig.)

The objective was to test the preservative potential of a dietary rosemary extract (RE) containing carnosic acid and carnosol (at 1:1 w:w) in chilled lamb patties packed in air, vacuum and 70/30 O2 /CO2 modified atmosphere. Three experimental diets, (C) control, (RE) C plus 600 mg RE/kg feed and (E) C plus 600 mg vitamin E/kg, were given to fattening lambs. Unlike the C- and E-diets, the RE-diet had a double antimicrobial and antioxidant effect on the lamb patties packed in all the environments studied. The RE-diet inhibited total viable and lactic acid bacteria and Enterobacteriaceae, but not Brochothrix thermosphacta and Pseudomonas spp. and also improved oxidative stability (measured as CIE Lab color and thiobarbituric reagent substances), appearance and odor. The E-diet had a better antioxidant effect than the RE-diet but had no antimicrobial effects. Escherichia coli and Salmonella spp. were not detected. The dietary use of RE was most suitable for preserving vacuum-packed meat, which is more exposed to spoilage by anaerobic bacteria, while the use of dietary vitamin E allowed better control of oxidation in the meat packed in a bacteriostatic and oxidizing environment.

    Urban air quality serves as an important function of the quality of urban life. Land use regression (LUR) modelling of air quality is essential for conducting health impacts assessment but more challenging in mountainous high-density urban scenario due to the complexities of the urban environment. In this study, a total of 21 LUR models are developed for seven kinds of air pollutants (gaseous air pollutants CO, NO2, NOx, O3, SO2 and particulate air pollutants PM2.5, PM10) with reference to three different time periods (summertime, wintertime and annual average of 5-year long-term hourly monitoring data from local air quality monitoring network) in Hong Kong. Under the mountainous high-density urban scenario, we improved the traditional LUR modelling method by incorporating wind availability information into LUR modelling based on surface geomorphometrical analysis. As a result, 269 independent variables were examined to develop the LUR models by using the "ADDRESS" independent variable selection method and stepwise multiple linear regression (MLR). Cross validation has been performed for each resultant model. The results show that wind-related variables are included in most of the resultant models as statistically significant independent variables. Compared with the traditional method, a maximum increase of 20% was achieved in the prediction performance of annual averaged NO2 concentration level by incorporating wind-related variables into LUR model development.

    Triticale (× Triticosecale sp. Wittmack ex A. Camus 1927) is an anthropogenic cereal designed to incorporate the functionality and high yield of wheat (Triticum spp. Linnaeus 1753) and durability of rye (Secale cereale Linnaeus 1753). The potential of triticale has remained largely unrealised, and in the 135 years since A. Stephen Wilson first crossed wheat and rye, triticale has mostly been used as animal feed. Growing demand for food resources has led to an increased interest in triticale development. Efforts to breed cultivars appropriate for baking have met with difficulty, although relatively new approaches to triticale end-use propose greater applicability for human consumption. Further, environmental awareness has generated interest in the use of triticale within biofuel production. We review environmental and genetic effects on triticale yield with a view towards increased demand on a hardy and useful cereal crop. We find triticale could satisfy many of the hopes originally placed upon it, and may be useful in foodstuffs and fuel, but only when growth environment is carefully considered.

    A considerable percentage of Polish children from agricultural families are engaged by their parents in performing work activities on farms. The performance of these tasks arouses various emotional reactions in children, from the feeling of threat, fear and anxiety, to the feeling of satisfaction, being contented and proud. The subjective feeling of happiness and life satisfaction is an extremely important factor affecting the mental health and functioning of a human being. The objective of the study was to show to what extent the quality of communication between children and parents, and the level of family cohesion and adaptability according to the Circumplex Model by D. H. Olson et al., modifies children's emotional reactions associated with the tasks performed. The study covered 192 children aged 12-13, whose parents were running a family farm. Growing up in a healthy family characterised by a balanced level of cohesion, adaptability and good communication with the father and mother, favours the occurrence in children of pleasant emotions in reaction to work which they undertake on behalf of their parents on a farm. In such families, more often than in families with bad communication and dysfunctional families (disengaged, rigid), children experience satisfaction, have a feeling of deepening bonds with their parents, and the feeling of being more adult and preparing themselves well for adult life. Family characteristics which are evidence of disorders in its functioning (lack of good communication with the father, mother, lack of bonds between family members, rigid, chaos in a family) co-occur with the child experiencing unpleasant emotional states in associated with the work performed, there occur feelings of dissatisfaction, unhappiness, unpleasantness, the feeling that it would be better to learn than to work.

    Full Text Available Green product management plays an important role in today's economy and people are increasing becoming more interested in green products. In this paper, we present an empirical study to measure the impact of customer perception, quality, environment concern and satisfaction on green customer loyalty. The study proposes two hypotheses, where the first hypothesis studies whether the quality of green product has direct impact on customer satisfaction and the second hypothesis examines whether quality of green product has direct impact on customer loyalty. The population of this paper includes all people who use paper-based drinking glass, napkin and packaging products and live in city of Tehran, Iran. Since not all people are involved in all parts of the city in such product, we have decided to select only those who are involved in using these kinds of products including hospitals, universities, etc. The sampling technique has distributed 300 questionnaires and gathered 283 good quality ones for analysis. The questionnaire consists of 19 questions in five different perspectives. The proposed study uses sequential equation modeling and the results have confirmed both hypotheses.

The higher values for soluble sugars contents were present in sun species: Lj, Pa, Ocb, Occ, Or. m, Ro and So; the lower values were obtained in low light species: Ps, Sp, Hp, Hs. The values of protein content do not show any clear trend or difference between sun and shade environments. The lowest values for the fresh weight: dry weight ratio are observed in sun species with the exception of Lj and Pa, while the highest value is observed in Pa, a succulent plant. The higher values of specific leaf mass (SLM(Kg DMm-2 are observed in sun plants. The two way ANOVA revealed that there were significant differences among species and between sun and low light environments for sugar content and FW: DW ratio, while SLM was significant for environments but no significant for species, and not significant for protein for both species and environments. The soluble sugar content, FW: DW ratio and SLM values obtained in this work, show a clear separation between sun and shade plants. The sugar content and FW:DW ratio are distinctive within the species,and the light environment affected sugar content, FW:DW ratio and SLM. These species may be shade-tolerant and able to survive in sunny environments. Perhaps these species originated in shaded environments and have been adapting to sunny habitats.Rev.Biol.Trop.53(1-2:23-28.Epub 2005 Jun 24En once especies de la familia Lamiaceae: Plecthranthus

    Over the past decades, scientists endeavored to comprehend oxidative stress in poultry spermatozoa and its relationship with fertilizing ability, lipid peroxidation (LPO), free-radical scavenging systems, and antioxidant therapy. Although considerable progress has been made, further improvement is needed in understanding how specific reactive oxygen species (ROS) and malondialdehyde (MDA, a toxic byproduct of LPO) disrupt organelles in avian spermatozoon. Hence, this study examined functional changes in chicken spermatozoa after incubation with different ROS, and their implications for the fertility. First, semen samples from 14 roosters were individually diluted and aliquoted into five equal parts: control, superoxide anion, hydrogen peroxide (H2O2), hydroxyl radicals, and MDA. After incubation with these molecules, aliquots were analyzed for motility, plasma membrane and acrosome integrity, mitochondrial activity, and LPO and DNA damage. Hydrogen peroxide was more detrimental for sperm motility than hydroxyl radicals, whereas the superoxide anion and MDA exhibited no differences compared with controls. In turn, plasma membrane and acrosome integrity, mitochondrial activity, LPO and DNA integrity rates were only affected by hydroxyl radicals. Thereafter, semen aliquots were incubated under the same conditions and used for artificial insemination. In accordance to our in vitro observations, H2O2 and hydroxyl radicals sharply reduced egg fertility, whereas superoxide anion and MDA only induced slight declines. Thus, chicken sperm function was severely impaired by H2O2 and hydroxyl radicals, but their mechanisms of action seemingly comprise different pathways. Further analysis regarding susceptibility of spermatozoon organelles to specific radicals in other poultry will help us to understand the development of interspecific differences in scavenging systems and to outline more oriented antioxidant approaches.

    Objective Evaluate outcomes of the lengthening temporalis myoplasty in facial reanimations. Study Design Case series with planned data collection. Setting Ospedali Riuniti, Bergamo, and AOUC Careggi, Florence, Italy. Subjects and Methods From 2011 to 2016, 11 patients underwent lengthening temporalis myoplasty; demographic data were collected for each. Pre- and postoperative photographs and videos were recorded and used to measure the smile angle and the excursion of the oral commissure, according to the SMILE system (Scaled Measurements of Improvement in Lip Excursion). All patients were tested with the Facial Disability Index, and they also completed a questionnaire about the adherence to physiotherapy indications. Results All patients demonstrated a significant improvement in functional parameters and in quality of life. On the reanimated side, the mean z-line and a-value, measured when smiling, significantly improved in all patients: from 22.6 mm (95% CI, 20.23-25.05) before surgery to 30.9 mm (95% CI, 27.82-33.99) after surgery ( P < .001) and from 100.5° (95% CI, 93.96°-107.13°) to 111.6° (95% CI, 105.63°-117.64°; P < .001), respectively. The mean postoperative dynamic gain, passing from rest to a full smile at the reanimated side, was 3.1 mm (95% CI, 1.30-4.88) for the z-line and 3.3° (95% CI, 1.26°-5.29°) for the a-value. The Facial Disability Index score increased from a preoperative mean of 33.4 points (95% CI, 28.25-38.66) to 49.9 points (95% CI, 47.21-52.60) postoperatively ( P < .001). Conclusions The lengthening temporalis myoplasty can be successfully used for smile reanimation, with satisfying functional and quality-of-life outcomes.

Such as water temperature, dissolved oxygen, ammonia nitrogen and nitrite, phytoplankton, chemical oxygen demand (CODMn. Results showed that, (1 the indexes of the dissolved oxygen, ammonia nitrogen, chemical oxygen demand(CODMn and nitrite of the experimental pond are all superior to that of the control pond, of which the concentration of the dissolved oxygen of the experimental pond is 8.37 mg/L which is higher than that of the control pond (5.7 mg/L. And, (CODMn in the experimental pond is 7.54 mg/L, lower than that in the control pond (10.19 mg/L. The difference between the control pond and the experimental pond was statistically significant (p<0.01. The ammonia nitrogen of the experimental pond is 0.1 mg/L, obviously lower than the control pond (0.16 mg/L. Besides, the nitrite is 0.13 mg/L in the experimental pond, lower than that of the control pond (0.21 mg/L. (2 Compared with the control pond, the experimental pond has quite higher general abundance of algae, with about 5.69×108 ind/L. Yet, there is no obvious difference between them. (3 Compared to the impeller oxygenation, the micropore oxygen aeration technology can be better to increase the dissolved oxygen in the aquaculture pond and improve the water quality. However, there is no significant influence to the phytoplankton abundance and diversity.

    The integration of quality management initiatives, particularly total quality management (TQM), and ergonomics has received increasing attention from scholars and practitioners. Above all, the question of how TQM programs relate to ergonomic aspects of organizational design and culture is at the center of this discussion. This study examines how elements of a "typical", Deming-inspired, TQM program in the public sector interact with the work environment. Elements of the TQM program were defined and measured using the Malcom Baldridge Award criteria. The specific elements examined were "Management Support of Quality", "Information and Analysis", "Human Resources", "Processes and Quality Results", and "Customer Focus and Satisfaction". The relationship between these TQM elements and the work environment were defined through five separate hypotheses. The work environment was described by the constructs "Supervisor Support", "Task Clarity", "Task Orientation", and "Innovation". Data were obtained through survey questionnaires administered to employees of four departments in a municipal government organization. Results supported three of the hypotheses, but produced some unanticipated outcomes with regard to the other two. Namely, "Management Support of Quality" was significantly related to "Supervisor Support", "Task Orientation", "Task Clarity" and "Innovation"; "Human Resources" was significantly related to "Supervisor Support"; "Processes and Quality Results" was significantly related to "Task Orientation" and "Innovation". Contrary to predicted "Information and Analysis" was negatively related to "Innovation", and "Customer Focus" was unrelated to any of the outcome variables. The relationships between these TQM elements and work environment dimensions are discussed. Implications for TQM and ergonomic practice are analyzed, and directions for future research proposed.

    This paper reports the investigation and analysis of the status and dynamic changes of ecological environment quality in the main stream of Songhua river basin. The evaluation index system was established and the eco-environment quality in the year of 2000 and 2008 was studied in depth. Based on our research, the trend of dynamic changes of the eco-environment quality and its origins have been further discussed: In the year of 2000, the range of evaluation index covered from 0.31 to 0.47. Harbin and Yichun was relatively better than the rest of study areas. In the year of 2008, except districts of Daqing and Qitaihe, the environmental quality of Songhua river basin has entirely improved, wherein the evaluation index of the eco-environment covered from 0.31 to 0.57. Particularly, the eco-environment quality of Hegang and Shuangyashan has obtained significant improvement, whereas the improvement of Jiamusi was not obvious. According to the evaluation results, the environmental quality in the study area has an upward trend with the average growth rate 0.13% per year.

    Numerous studies suggest a positive relationship between the home literacy environment (HLE) and children's language and literacy skills, yet very little research has focused on the HLE of children with language impairment (LI). Children with LI are at risk for reading difficulties; thus, understanding the nature and frequency of their home literacy interactions is warranted. To identify unique HLE profiles within a large sample of children with LI, and to determine relevant caregiver- and child-specific factors that predict children's profile membership. Participants were 195 kindergarten and first-grade children with LI who were receiving school-based language therapy. Caregivers completed a comprehensive questionnaire regarding their child's HLE, and the extent to which their child engaged in shared book reading, were taught about letters, initiated or asked to be read to, and chose to read independently. Caregivers also answered questions regarding the highest level of maternal education, caregiver history of reading difficulties, and caregiver reading habits. Children completed a language and literacy battery in the fall of their academic year. Latent profile analyses indicated a three-profile solution, representing high, average and low frequency of the selected HLE indicators. Multinomial regression further revealed that caregivers' own reading habits influenced children's profile membership, as did child age and language abilities. These results highlight the considerable variability in the frequency of home literacy interactions of children with LI. Future work examining relations between familial reading practices and literacy outcomes for children with LI is warranted. © 2016 Royal College of Speech and Language Therapists.

    A haemophilia-specific health-related quality-of-life questionnaire (named 'Hemofilia-QoL') was developed to assess quality-of-life in adults with haemophilia, and was psychometrically tested. Seventy-three interviews with haemophilia patients and health care professionals were used to generate the items included in the questionnaire, and expert ratings on the items formulated were used to screen them for potential omission. This was followed by psychometric testing in a sample of 35 patients. Preliminary psychometric testing of the revised questionnaire version, which contains 10 domains (physical health, physical role, joint damage, pain, treatment satisfaction, emotional role, mental health, social support), showed acceptable reliability (alpha = 0.94 for the Hemofilia-QoL total score) and validity, and this will be examined in a subsequent study with a larger patient sample.

    In prey species, vigilance is an important part of the decision making process related to predation risk effects. Therefore, understanding the mechanisms shaping vigilance behavior provides relevant insights on factors influencing individual fitness. We investigated the role of extrinsic and intrinsic factors on vigilance behavior in Mediterranean mouflon (Ovis gmelini musimon×Ovis sp.) in a study site spatially and temporally contrasted in human pressures. Both sexes were less vigilant in the wildlife reserve compared to surrounding unprotected areas, except for males during the hunting period. During this period, males tended to be less strictly restricted to the reserve than females what might lead to a pervasive effect of hunting within the protected area, resulting in an increase in male vigilance. It might also be a rutting effect that did not occur in unprotected areas because males vigilance was already maximal in response to human disturbances. In both sexes, yearlings were less vigilant than adults, probably because they traded off vigilance for learning and energy acquisition and/or because they relied on adult experience present in the group. Similarly, non-reproductive females benefited of the vigilance effort provided by reproductive females when belonging to the same group. However, in the absence of reproductive females, non-reproductive females were as vigilant as reproductive females. Increasing group size was only found to reduce vigilance in females (up to 17.5%), not in males. We also showed sex-specific responses to habitat characteristics. Females increased their vigilance when habitat visibility decreased (up to 13.8%) whereas males increased their vigilance when feeding on low quality sites, i.e., when concomitant increase in chewing time can be devoted to vigilance with limited costs. Our global approach was able to disentangle the sex-specific sources of variation in mouflon vigilance and stressed the importance of reserves in managing

    Full Text Available Stable carbon and nitrogen isotope signals in plant tissues integrate plant-environment interactions over long periods. In this study, we hypothesized that humid alpine life conditions are narrowing the scope for significant deviations from common carbon, water and nitrogen relations as captured by stable isotope signals. We explored the variation in δ13C and δ15N in 32 plant species from tissue type to ecosystem scale across a suite of locations at c. 2500 m elevation in the Swiss Alps. Foliar δ13C and δ15N varied among species by about 3-4 ‰ and 7-8 ‰ respectively. However, there was no overall difference in means of δ13C and δ15N for species sampled in different plant communities or when bulk plant dry matter harvests of different plant communities were compared. δ13C was found to be highly species specific, so that the ranking among species was mostly maintained across 11 habitats. However, δ15N varied significantly from place to place in all species (a range of 2.7 ‰ except in Fabaceae (Trifolium alpinum and Juncaceae (Luzula lutea. There was also a substantial variation among individuals of the same species collected next to each other. No difference was found in foliar δ15N of non-legumes, which were either collected next to or away from the most common legume, T. alpinum. δ15N data place Cyperaceae and Juncaceae, just like Fabaceae, in a low discrimination category, well separated from other families. Soil δ15N was higher than in plants and increased with soil depth. The results indicate a high functional diversity in alpine plants that is similar to that reported for low elevation plants. We conclude that the surprisingly high variation in δ13C and δ15N signals in the studied high elevation plants is largely species specific (genetic and insensitive to obvious environmental cues.

    We propose the use of the Least Absolute Shrinkage and Selection Operator (LASSO) regression method in order to predict the Cumulative Mean Squared Error (CMSE), incurred by the loss of individual slices in video transmission. We extract a number of quality-relevant features from the H.264/AVC video sequences, which are given as input to the LASSO. This method has the benefit of not only keeping a subset of the features that have the strongest effects towards video quality, but also produces accurate CMSE predictions. Particularly, we study the LASSO regression through two different architectures; the Global LASSO (G.LASSO) and Local LASSO (L.LASSO). In G.LASSO, a single regression model is trained for all slice types together, while in L.LASSO, motivated by the fact that the values for some features are closely dependent on the considered slice type, each slice type has its own regression model, in an e ort to improve LASSO's prediction capability. Based on the predicted CMSE values, we group the video slices into four priority classes. Additionally, we consider a video transmission scenario over a noisy channel, where Unequal Error Protection (UEP) is applied to all prioritized slices. The provided results demonstrate the efficiency of LASSO in estimating CMSE with high accuracy, using only a few features. les that typically contain high-entropy data, producing a footprint that is far less conspicuous than existing methods. The system uses a local web server to provide a le system, user interface and applications through an web architecture.

  5. Impact of hydroelectric projects on river environment: Analysis of water quality changes in Ningxia Reach of Yellow River

    2008-06-01

    Full Text Available In this paper, the relationship between hydroelectric projects and the river environment is analyzed. Recently, the large-scale regulation of runoff by large hydroelectric projects in the Ningxia Reach of the Yellow River has altered natural runoff processes, causing an increase in the probability of low discharge and an overall adjustment of riverbed evolution and river characteristics. During low-flow years, the combined effects of these two changes can weaken the self-purification capacity and reduce the water environmental capacity of the river. This is one of the main reasons for the recent decrease of water quality in the Ningxia Reach. This research shows that it is necessary to implement river training projects to maintain stable flow paths, not only for adjusting river regimes and for flood control, but also for increasing the self-purification capacity and the water environmental capacity of the river. Methods and proposals for coordinating the operation of hydroelectric projects with the protection of the river environment are presented in the interest of promoting sustainable development.

    In this paper, the relationship between hydroelectric projects and the river environment is analyzed. Recently, the large-scale regulation of runoff by large hydroelectric projects in the Ningxia Reach of the Yellow River has altered natural runoff processes, causing an increase in the probability of low discharge and an overall adjustment of riverbed evolution and river characteristics. During low-flow years, the combined effects of these two changes can weaken the self-purification capacity and reduce the water environmental capacity of the river. This is one of the main reasons for the recent decrease of water quality in the Ningxia Reach. This research shows that it is necessary to implement river training projects to maintain stable flow paths, not only for adjusting river regimes and for flood control, but also for increasing the self-purification capacity and the water environmental capacity of the river. Methods and proposals for coordinating the operation of hydroelectric projects with the protection of the river environment are presented in the interest of promoting sustainable development.

    This is one of seven interlinked systematic reviews undertaken on behalf of the European Academy of Allergy and Clinical Immunology as part of their Guidelines for Food Allergy and Anaphylaxis, which focuses on instruments developed for IgE-mediated food allergy. Disease-specific questionnaires...... are significantly more sensitive than generic ones in measuring the response to interventions or future treatments, as well as estimating the general burden of food allergy. The aim of this systematic review was therefore to identify which disease-specific, validated instruments can be employed to enable assessment....... From the 17 eligible studies, we identified seven disease-specific HRQL instruments, which were then subjected to detailed quality appraisal. This revealed that these instruments have undergone formal development and validation processes, and have robust psychometric properties, and therefore provide...

    Full Text Available Abstract Background Chronic suppurative otitis media (CSOM is frequently associated with symptoms of inflammation like discharge from the ear or pain. In many cases, patients suffer from hearing loss causing communication problems and social withdrawal. The objective of this work was to collect prospective audiological data and data on general and disease-specific quality of life with validated quality of life measurement instruments to assess the impact of the disease on health-related quality of life (HR-QOL. Methods 121 patients were included in the study. Patients were clinically examined in the hospital before and 6 months after surgery including audiological testing. They filled in the quality of life questionnaires SF-36 and Chronic Otitis Media Outcome Test 15 (COMOT-15 pre-operatively and 6 and 12 months post-operatively, respectively. Results Complete data records from 90 patients were available for statistical analysis. Disease-specific HR-QOL in patients with CSOM improved after tympanoplasty in all the scales of the COMOT-15. There was no difference in HR-QOL assessment between patients with mesotympanic respectively epitympanic CSOM. However, we did find the outcome to be worse in patients who received revision surgery compared with those receiving primary surgery. Audiometric findings correlated very well with the subscale hearing function from the COMOT-15 questionnaire. General HR-QOL measured with the SF-36 was not significantly changed by tympanoplasty. Conclusions Tympanoplasty did lead to a significant improvement of disease-specific HR-QOL in patients with CSOM while general HR-QOL did not change. Very well correlations were found between the subscale hearing function from the COMOT-15 questionnaire and audiological findings. Revision surgery seems to be a predictor for a worse outcome.

    Only a part of all automation equipment which has been designed for control of power units in power generating plants is actually used and must, moreover, be continuously inspected by station personnel. The two main reasons for this are an inadequate level of preparedness for automation and insufficiently high quality of the control system, characterized by steadily increasing complexity and decreasing reliability as well as high cost and poor accessibility. In order to remedy this situation, experimental studies on a correct approach to the problem in the planning and design stage already had begun in the Soviet Union in the early nineteen sixties and have continued ever since. The basic structure of a control system in a power plant consist of five subsystems: automatic control, logic control, protective shielding, remote control and data display. This structure has been modified by utilization of computer technology. With redundancy regarded as a tradeoff between cost of shutdown and cost of control hardware, a two-tier structure is so far found to be optimum. Here decentralized simple special-purpose equipment executes simple algorithms at the lower level, while the process control computer aids execution of complex algorithms at the upper level. Memory elements interface the two levels, for reducing the adverse economic consequences of computer failure. In a typical case of maneuvering with a process control computer, a 200 MW power unit under variable load conditions will reduce the total unpreparedness time over a 7500 hours operating period from 30 h to 2 h. 6 references, 4 figures.

    This study was conducted to explore the culture-specific roles of emotion, relationship quality, and self-esteem in determining life satisfaction. It was hypothesized that maintaining good interpersonal relationships would make individuals in collectivistic cultures not only feel good about their lives but also feel better about themselves. Furthermore, two emotion variables--emotional expression and emotion differentiation--were proposed as possible determinants of relationship quality. It was hypothesized that emotional expressiveness would be more important for maintaining good interpersonal relationships in individualistic societies but emotion differentiation would be more important in collectivistic cultures. These hypotheses were tested with Euro-American, Asian American, Korean, and Chinese groups using multigroup analyses in a structural equation model. Results supported all proposed hypotheses and indicated that emotion differentiation contributes to maintaining good interpersonal relationships in collectivistic cultures, which contributes to self-esteem and satisfaction with life.

    2016-03-01

    Full Text Available The objective of this article is to develop and apply a specific discounting cash flow (DCF approach to evaluate investment in renovation to improve building quality, thus increasing energy efficiency. In this article, we develop and apply a specific net present value (NPV and an internal rate of return (IRR approach to quantify the value created for the owners of the building by the investment in renovation via energy-saving investments that produce positive externalities. The model has an applied interest because, in recent years, a lot of investments in real estate were made by owners in order to increase the green quality of the buildings, and several funds of public aid were provided by the government to stimulate these energy-saving investments. The model proposed here is applied to a case study of a 16-apartment building located in northern Italy considers the model attempts to quantify the initial investment value, the energy savings, the tax deduction of the initial investment and the terminal value of the investment as the increase in building value. The analysis shows that the model is consistent in evaluating investments to improve building quality, and investments within the context of the specific case study considered in the research have IRRs ranging from a minimum of 4.907% to a maximum of 12.980%. It could even be useful to consider a sample of cases to verify whether our results are representative of this specific case study. The model could represent a useful tool for consumers in evaluating their own investments in building renovation, from a stand-alone perspective and even by comparing them with other types of investment. The research could be developed in the future to quantify the social welfare generated by public spending via tax deductions to reduce the costs of investment in energy savings for buildings and could even be applied to new real estate projects in comparing different construction technologies and even

    This study was conducted for the purpose of establishing a quality-assurance (QA) system for brachytherapy that can ensure patient-specific QA by enhancing dosimetric accuracy for the patient's therapy plan. To measure the point-absorbed dose and the 2D dose distribution for the patient's therapy plan, we fabricated a solid phantom that allowed for the insertion of an applicator for patient-specific QA and used an ion chamber and a film as measuring devices. The patient treatment plan was exported to the QA dose-calculation software, which calculated the time weight of dwell position stored in the plan DICOM (Digital Imaging and Communications in Medicine) file to obtain an overall beam quality correction factor, and that correction was applied to the dose calculations. Experiments were conducted after importing the patient's treatment planning source data for the fabricated phantom and inserting the applicator, ion chamber, and film into the phantom. On completion of dose delivery, the doses to the ion chamber and film were checked against the corresponding treatment plan to evaluate the dosimetric accuracy. For experimental purposes, five treatment plans were randomly selected. The beam quality correction factors for ovoid and tandem brachytherapy applicators were found to be 1.15 and 1.10 - 1.12, respectively. The beam quality correction factor in tandem fluctuated by approximately 2%, depending on the changes in the dwell position. The doses measured by using the ion chamber showed differences ranging from -2.4% to 0.6%, compared to the planned doses. As for the film, the passing rate was 90% or higher when assessed using a gamma value of the local dose difference of 3% and a distance to agreement of 3 mm. The results show that the self-fabricated phantom was suitable for QA in clinical settings. The proposed patient-specific QA for the treatment planning is expected to contribute to reduce dosimetric errors in brachytherapy and, thus, to enhancing treatment

    A water quality analysis and modeling study is currently being conducted on the Martinez Creek, a small catchment within Cibolo watershed, a sub-basin of the San Antonio River, Texas. Several other major creeks, such as Salatrillo, Escondido, and Woman Hollering merge with Martinez Creek. Land use and land cover analysis shows that the major portion of the watershed is dominated by residential development with average impervious cover percentage of approximately 40% along with a some of agricultural areas and brushlands. This catchment is characterized by the presence of three small wastewater treatment plants. Previous site visits and sampling of water quality indicate the presence of algae and fecal coliform bacteria at levels well above state standards at several locations in the catchment throughout the year. Due to the presence of livestock, residential development and wastewater treatment plants, a comprehensive understanding of water quality is important to evaluate the sources and find means to control pollution. As part of the study, a spatial and temporal water quality analyses of conventional parameters as well as emerging contaminants, such as veterinary pharmaceuticals and microbial pathogens is being conducted to identify critical locations and sources. Additionally, the Hydrologic Simulation Program FORTRAN (HSPF) will be used to identify best management practices that can be incorporated given the projected growth and development and feasibility.

    Organ-specific dose reduction (OSDR) algorithms can reduce radiation on radiosensitive organs up to 59 %. This study evaluates the influence of a new OSDR algorithm on image quality of head and neck computed tomographic angiography (CTA) in clinical routine. Sixty-two consecutive patients (68 {+-} 13 years) were randomised into two groups and imaged using 128-row multidetector CT. Group A (n = 31) underwent conventional CTA and group B (n = 31) CTA with a novel OSDR algorithm. Subjective and objective image quality were statistically compared. Subjective image quality was rated on a five-point scale. Signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were calculated with region-of-interest measurements. The SNR of the common carotid artery and middle cerebral artery was 53.6 {+-} 22.7 and 43.3 {+-} 15.3 (group A) versus 54.1 {+-} 20.5 and 46.2 {+-} 14.6 (group B). The CNR was 40.0 {+-} 19.3 and 29.7 {+-} 12.0 (group A) compared with 40.7 {+-} 16.8 and 32.9 {+-} 10.9 (group B), respectively. Subjective image quality was excellent in both groups (mean score 4.4 {+-} 0.7 versus 4.4 {+-} 0.6). Differences between the two groups were not significant. The novel OSDR algorithm does not compromise image quality of head and neck CTA. Its application can be recommended for CTA in clinical routine to protect the thyroid gland and ocular lenses from unnecessary high radiation. (orig.)

  18. The bubbles or the boiling pot? An ecosystemic approach to culture, environment and quality of life

    Pilon, André Francisco

    2009-03-01

    For the diagnosis and prognosis of the problems of quality of life, a multidisciplinary ecosystemic approach encompasses four dimensions of being-in-the-world, as donors and recipients: intimate, interactive, social and biophysical. Social, cultural and environmental vulnerabilities are understood and dealt with, in different circumstances of space and time, as the conjugated effect of all dimensions of being-in-the-world, as they induce the events (deficits and assets), cope with consequences (desired or undesired) and contribute for change. Instead of fragmented and reduced representations of reality, diagnosis and prognosis of cultural, educational, environmental and health problems considers the connections (assets) and ruptures (deficits) between the different dimensions, providing a planning model to develop and evaluate research, teaching programmes, public policies and field projects. The methodology is participatory, experiential and reflexive; heuristic-hermeneutic processes unveil cultural and epistemic paradigms that orient subject-object relationships; giving people the opportunity to reflect on their own realities, engage in new experiences and find new ways to live better in a better world. The proposal is a creative model for thought and practice, providing many opportunities for discussion, debate and development of holistic projects integrating different scientific domains (social sciences, psychology, education, philosophy, etc.).

    Asphalts, biochemically degraded oil, contain persistent, water-soluble compounds that pose a significant challenge to the isolation of PCR quality DNA. The adaptation of existing DNA purification protocols and commercial kits proved unsuccessful at overcoming this hurdle. Treatment of aqueous asphalt extracts with a polyamide resin afforded genomic microbial DNA templates that could readily be amplified by PCR. Physicochemically distinct asphalt samples from five natural oil seeps successfully generated the expected 291 bp amplicons targeting a region of the 16S rRNA gene, illustrating the robustness of the method. DNA recovery yields were in the 50-80% range depending on how the asphalt sample was seeded with exogenous DNA. The scope of the new method was expanded to include soil with high humic acid content. DNA from soil samples spiked with a range of humic acid concentrations was extracted with a commercial kit followed by treatment with the polyamide resin. The additional step significantly improved the purity of the DNA templates, especially at high humic acid concentrations, based on qPCR analysis of the bacterial 16S rRNA genes. The new method has the advantages of being inexpensive, simple, and rapid and should provide a valuable addition to protocols in the field of petroleum and soil microbiology.

    2009-01-01

    A methodology for identifying volatile organic compounds (VOC) and determining air quality of indoor air has been developed. The air samples are collected using pump samplers by the inhabitants when they perceive odorous and/or discomfort episodes. Glass multi-sorbent tubes are connected to the pump samplers for the retention of VOC. The analysis is performed by automatic thermal desorption (ATD) coupled with gas chromatography-mass spectrometry (GC/MS). This methodology can be applied in cases of sick building syndrome (SBS) evaluation, in which building occupants experience a series of varied symptoms that appear to be linked to time spent in the building. Chemical pollutants concentrations (e.g., VOC) have been described to contribute to SBS. To exemplify the methodology, a qualitative determination and an evaluation of VOC present were performed in a dwelling where the occupants experienced the SBS symptoms. Higher total VOC (TVOC) value was detected in episodes in indoor air (1.33 ( 1.53 mg/m3) compared to outdoor air (0.71 ( 0.46 mg/m3). The concentrations of individual VOCs, such as ethanol, acetone, isopropanol, 1-butanol, acetic acid, acetonitrile and 1-metoxy-2-propanol, were also higher than the expected for a standard dwelling. The external source of VOC was found to be a not declared activity of storage and manipulation of solvents located at the bottom of a contiguous building.

    Since a rise in dissolved organic carbon (DOC) concentrations has been observed for surface waters at least over the last two decades, a change in weather conditions (temperature and precipitations) has been proposed to partly explain this increase. While the majority of DOC delivery from soils to stream occurs during rainfall events, a better understanding of the rainfall influence on DOC release is needed. This study has been conducted in Brittany, western France, on agricultural experimental plots receiving either cattle manure (CM) or pig slurry (PS) as fertilizers in accordance with local practices. Each plot was instrumented with a flow meter and an auto sampler for runoff measurements. The results show that export of DOC during high intensity events is higher than during lower intensity rainfalls. Fertilization has a noticeable impact on total organic carbon (TOC) fluxes with an increase of five to seven folds for PS and CM respectively. If TOC shock load occurs shortly after the rainfall peak, DOC maximum appears with the first flush of the event. Organic carbon (OC) is mainly under colloidal (41.2%) and soluble (23.9%) forms during the first stage of a rainfall event and a control of rainfall intensity on OC colloidal transport is suggested. These findings highlight the potential risk of receiving water quality degradation due to the increase of heavier rainfall events with climate change in temperate areas.

    In order to minimize adverse health effects and increase the benefits of physical activity, it is important to systematize indoor air quality study in environments used for physical exercise and sports. To investigate and analyze the scientific production related to indoor air quality of environments used for physical exercise and sports practice through a bibliometric analysis. The databases Scielo, Science Direct, Scopus, Lilacs, Medline via Pubmed, and SportDiscus were searched from their inception to March 2016. Bibliometric analysis was performed for authors, institutions, countries, and collaborative networks, in relation to publication year, theme, citation network, funding agency, and analysis of titles and keywords of publications. Country, area, and impact factor of the journals were analyzed. Of 1281 studies screened, 34 satisfied the inclusion criteria. The first publication occurred in 1975. An increase in publications was observed in the last 15 years. Most of the studies were performed by researchers in the USA, followed by Portugal and Italy. Seventeen different scientific journals have published studies on the subject, and most are in the area of Environmental Sciences. It was noted that the categories of author keywords associated with "Pollutants," "Sport Environment," and "Physical Exercise" were the most commonly used in most studies. A total of 68% of the studies had at least one funding agency, and 81% of studies published in the last decade had funding. Our results demonstrate that there is recent exponential growth, driven in the last decade by researchers in environmental science from European institutions. Copyright © 2017 Elsevier Ltd.

    Full Text Available Introduction: celiac disease is a chronic condition that requires continued treatment, with the resultant impact on health-related quality of life (HRQOL of people who suffer it. Most studies in this field have used generic questionnaires to measure HRQOL in celiac patients. It was therefore decided to conduct a study to translate into Spanish and validate a specific questionnaire for celiac disease, the Celiac Disease Quality Of Life Survey (CD-QOL. Objectives: to translate and validate in Spanish the specific celiac disease questionnaire CD-QOL. Methods: a multicenter, prospective, observational study was designed consisting of two phases: In the first phase, the questionnaire was translated and adapted into Spanish using the translation/back translation procedure and an understandability study. In the second phase, internal consistency of the translated questionnaire was analyzed. For this, results of the CD-QOL were compared to those of EuroQol and the Daily Fatigue Impact Scale (D-FIS. Understandability of the translated and adapted questionnaire was tested in six patients, and the validation study was done in 298 celiac patients (201 treated with a gluten-free diet and 97 at diagnosis. Results: in both celiac groups, Cronbach's alpha coefficient was high (0.90, feasibility was excellent (99.2 % of patients completed all questions, and there were no ceiling and floor effects. Spearman correlation to EuroQol and D-FIS was statistically significant (p < 0.05. CD-QOL score was different depending on whether state of health was good, fair, or poor based on the EuroQol score. Conclusion: the Spanish version of the CD-QOL is a valid tool for measuring HRQOL in celiac patients.

    Sarcopenia, defined by a progressive and generalized loss of muscle mass and muscle function, is associated with many harmful clinical consequences. Several studies have reported the impact of sarcopenia on health-related quality of life (HRQoL) using generic quality of life (QoL) questionnaires. The results of these observational studies are quite heterogenous. Indeed, generic tools may not be able to detect subtle effects of sarcopenia on QoL. Recently, a sarcopenia-specific HRQoL questionnaire was developed and validated in a population of sarcopenic subjects to more accurately assess the impact of sarcopenia on QoL. Areas covered: The purpose of this review is to present evidence regarding the impact of sarcopenia on QoL and to introduce a new specific HRQoL questionnaire, the SarQoL®. Expert commentary: The self-administered SarQoL®, initially developed in French, comprises 55 items translated into 22 questions. The questionnaire has been shown to be understandable, valid, consistent, and reliable and can therefore be recommended for clinical and research purposes. The questionnaire is now available in 11 different languages with another 20 translations in progress. The instrument's sensitivity to change still needs to be assessed in future longitudinal studies.

    Vehicle positioning is a key factor for numerous information and assistance applications that are included in vehicles and for which satellite positioning is mainly used. However, this positioning process can result in errors and lead to measurement uncertainties. These errors come mainly from two sources: errors and simplifications of digital maps and errors in locating the vehicle. From that inaccurate data, the task of assigning the vehicle's location to a link on the digital map at every instant is carried out by map-matching algorithms.

    Full Text Available Vehicle positioning is a key factor for numerous information and assistance applications that are included in vehicles and for which satellite positioning is mainly used. However, this positioning process can result in errors and lead to measurement uncertainties. These errors come mainly from two sources: errors and simplifications of digital maps and errors in locating the vehicle. From that inaccurate data, the task of assigning the vehicle’s location to a link on the digital map at every instant is carried out by map-matching algorithms. These algorithms have been developed to fulfil that need and attempt to amend these errors to offer the user a suitable positioning. In this research; an algorithm is developed that attempts to solve the errors in positioning when the Global Navigation Satellite System (GNSS signal reception is frequently lost.

    Mountain lakes represent essential stages for aquatic species on their way colonizing habitats of more elevated regions.Despite extensive biological and chemical study,only little has been reported about the species number and density of freshwater molluscs in these waters.The article presented here elucidates the dispersal of aquatic gastropods and bivalves in 12 mountain lakes that are commonly situated in the Eastern Alps,Austria.Molluscs were recorded at 120 sample points,where a total of 13 species (8 gastropods and 5 bivalves) could be determined.Species distribution data as well as results from contemporarily conducted physico-chemical factor recording were subject to weighted average analysis.In addition,a global marginality coefficient indicating the particularity of a habitat inhabited by a focal species as well as a global tolerance coefficient expressing the width of a niche occupied by this species were computed.Species-environment relationships exhibited that species number and specific density decrease with increasing geographic altitude,declining water temperature,and decreasing amount of submerged vegetation.Whilst waters of the montane altitude level are partly charcterized by high number of mollusc species (>10),lakes of the subalpine altitude level commonly bear 1 or 2 species with <<1 ind./m2.As proposed by the results of statistics,9 of the 13 mollusc species are characterized by a pronounced behaviour as specialists with respect to most environmental factors.The four remaining species,Pisidium casertanum,Galba truncatula,Radix labiata,and Radix balthica,act as generalists which increases their pioneering role in the long-term occupation of the Central-alpine region.

    Research has suggested that psychological stress is positively associated with asthma morbidity. One major source of stress in adulthood is one's occupation. However, to date, potential links of work stress with asthma control or asthma-specific quality of life have not been examined. We aimed to address this knowledge gap. In 2014/2015, we conducted a cross-sectional study among adults with asthma in Germany (n = 362). For the current analyses that sample was restricted to participants in employment and reporting to have never been diagnosed with chronic obstructive pulmonary disease (n = 94). Work stress was operationalized by the 16-item effort-reward-imbalance (ERI) questionnaire, which measures the subcomponents "effort", "reward" and "overcommitment." Participants further completed the Asthma Control Test and the Asthma Quality of Life Questionnaire-Sydney. Multivariable associations were quantified by linear regression and logistic regression. Effort, reward and their ratio (i.e. ERI ratio) did not show meaningful associations with asthma morbidity. By contrast, increasing levels of overcommitment were associated with poorer asthma control and worse quality of life in both linear regression (ß = -0.26, p = 0.01 and ß = 0.44, p < 0.01, respectively) and logistic regression (odds ratio [OR] = 1.87, 95% confidence interval [CI] = 1.14-3.07 and OR = 2.34, 95% CI = 1.32-4.15, respectively). The present study provides initial evidence of a positive relationship of work-related overcommitment with asthma control and asthma-specific quality of life. Longitudinal studies with larger samples are needed to confirm our findings and to disentangle the potential causality of associations.

    Full Text Available - Classical methods for software development require high costs and problems of communication between development teams, project risks and delays in the delivery of its services. In this work, the aim is to develop a perceptron model to demonstrate the ability to control, service quality assessment and decision-making in IT (Information Technology. For this, we used perceptron network techniques, standards of service quality measures and risk analysis model of applied projects in software engineering. With the network perceptron model implementation was possible to simulate the application of development in several requests for applications for software, in order to meet the management of schedules in all phases of the life cycle of the projects carried out. The tests with the perceptron model were applied in it environments to meet service requests from various fields. The results and analyses presented in these projects demonstrate that communication between development teams were more consistent. It was also possible to predict with more accuracy the delivery of services, decision making and risk reduction projects.

    We aimed to develop site-specific sediment quality guidelines (SQGs) for two estuarine and port zones in Southeastern Brazil (Santos Estuarine System and Paranaguá Estuarine System) and three in Southern Spain (Ría of Huelva, Bay of Cádiz, and Bay of Algeciras), and compare these values against national and traditionally used international benchmark values. Site-specific SQGs were derived based on sediment physical-chemical, toxicological, and benthic community data integrated through multivariate analysis. This technique allowed the identification of chemicals of concern and the establishment of effects range correlatively to individual concentrations of contaminants for each site of study. The results revealed that sediments from Santos channel, as well as inner portions of the SES, are considered highly polluted (exceeding SQGs-high) by metals, PAHs and PCBs. High pollution by PAHs and some metals was found in São Vicente channel. In PES, sediments from inner portions (proximities of the Ponta do Félix port's terminal and the Port of Paranaguá) are highly polluted by metals and PAHs, including one zone inside the limits of an environmental protection area. In Gulf of Cádiz, SQGs exceedences were found in Ria of Huelva (all analysed metals and PAHs), in the surroundings of the Port of Cádiz (Bay of Cádiz) (metals), and in Bay of Algeciras (Ni and PAHs). The site-specific SQGs derived in this study are more restricted than national SQGs applied in Brazil and Spain, as well as international guidelines. This finding confirms the importance of the development of site-specific SQGs to support the characterisation of sediments and dredged material. The use of the same methodology to derive SQGs in Brazilian and Spanish port zones confirmed the applicability of this technique with an international scope and provided a harmonised methodology for site-specific SQGs derivation.

    The litterbag method was used to study the decomposition of wetland plant root in three wetlands along a water level gradient in the Sanjiang Plain, Northeast China. These wetlands are Calamagrostis angustifolia ( C.aa), Carex meyeriana (C.ma) and Carex lasiocarpa (C.la). The objective of our study is to evaluate the influence of environment and substrate quality on decomposition rates in the three wetlands. Calico material was used as a standard substrate to evaluate environmental influences. Roots native to each wetland were used to evaluate decomposition dynamics and substrate quality influences. Calico mass loss was statistically different among the three wetlands in the upper soil profile (0-10 cm) and in the lower depth range (10-20 cm). Hydrology, temperature and pH all influence calico decomposition rates in different ways at different depths of the soil profiles. The decomposition rates of native roots declined differentially with the increase of depth in the soil profiles. The mass loss of native roots showed a statistical decrease among the three wetlands in the upper soil profile (0-10 cm) and in the lower depth range (10-20 cm) as C.ma wetland C.aa wetland C.la wetland. Both the C:P ratio and N:P ratio were positively interrelated with decomposition rates. Decomposition rates were negatively related to initial P concentration in all three wetlands, indicating that P concentration seems to be an important factor controlling the fitter loss.

    Bio-functionalized three-dimensional (3D) structures fabricated by direct laser writing (DLW) are structurally and mechanically well-defined and ideal for systematically investigating the influence of three-dimensionality and substrate stiffness on cell behavior. Here, we show that different fibroblast-like and epithelial cell lines maintain normal proliferation rates and form functional cell-matrix contacts in DLW-fabricated 3D scaffolds of different mechanics and geometry. Furthermore, the molecular composition of cell-matrix contacts forming in these 3D micro-environments and under conventional 2D culture conditions is identical, based on the analysis of several marker proteins (paxillin, phospho-paxillin, phospho-focal adhesion kinase, vinculin, β1-integrin). However, fibroblast-like and epithelial cells differ markedly in the way they adapt their total cell and nuclear volumes in 3D environments. While fibroblast-like cell lines display significantly increased cell and nuclear volumes in 3D substrates compared to 2D substrates, epithelial cells retain similar cell and nuclear volumes in 2D and 3D environments. Despite differential cell volume regulation between fibroblasts and epithelial cells in 3D environments, the nucleus-to-cell (N/C) volume ratios remain constant for all cell types and culture conditions. Thus, changes in cell and nuclear volume during the transition from 2D to 3D environments are strongly cell type-dependent, but independent of scaffold stiffness, while cells maintain the N/C ratio regardless of culture conditions.

    Full Text Available Abstract Background According to market investigation, two kinds of Polygoni Multiflori Radix decoction pieces with different specifications are commercially available: irregular thick slices (0.7-1.3 cm and length-wise into thin slices (0.11-0.2 cm. The objective of this study was to evaluate the quality of various samples of Polygoni Multiflori Radix decoction pieces and its dregs. Results A simple and reliable high performance liquid chromatographic method was developed for determination the contents of 2,3,5,4′-tetrahydroxystilbene-2-O-β-D- glucopyranoside (THSG, emodin and physcion, which were considered to be potent active ingredients. The results showed that the contents of THSG, emodin and physcion varied in samples of different diameters and thicknesses. The results also indicated the dregs of Polygoni Multiflori Radix still contained a considerable amount of THSG, emodin and physcion. Conclusion The various commercial specifications of Polygoni Multiflori Radix sold in the markets did not correlate with their prices, and the dregs of Polygoni Multiflori Radix can be further utilized.

    Microbial and water-quality measurements are collected during storm events under a variety of meteorological and land-use conditions in order to 1) identify risk of Cryptosporidium oocysts, Giardia cysts and other constituents, including microbial indicator organisms, entering surface waters from various land uses during periods of surface runoff; 2) optimize storm sampling procedures for these parameters; and 3) optimize strategies for accurate determination of constituent loads. The investigation is focused on four isolated land uses: forested with free ranging wildlife, beaver influenced forested with free ranging wildlife, residential/commercial, and dairy farm grazing/pastureland using an upstream and downstream sampling strategy. Traditional water-quality analyses include pH, temperature, turbidity, conductivity, total suspended solids, total phosphorus, total Kjeldahl-nitrogen, and ammonia nitrogen, Giardia cysts and Cryptosporidium oocysts. Total coliforms and fecal coliforms are measured as industry standard microbial analyses. Sorbitol-fermenting Bifidobacteria, Rhodococcus coprophilus, Clostridium perfringens spores, and Somatic and F-specific coliphages are measured at select sites as potential alternative source-specific indicator organisms. Upon completion of the project, the final database will consist of wet weather transport data for a set of parameters during twenty-four distinct storm-events in addition to monthly baseline data. A subset of the results to date will be presented, with focus placed on demonstrating the impact of beaver on constituent loadings over a variety of hydrologic and meteorological conditions.

    Septal deviations might cause nasal obstruction and negative impact on the quality of life of individuals. The efficacy of septoplasty for treatment of septal deviation and the predictors of satisfactory surgical outcomes remain controversial. Technical variability, heterogeneity of research samples and absence of a solid tool for clinical evaluation are the main hindrances to the establishment of reliable statistical data regarding the procedure. To evaluate the clinical improvements in the disease-specific quality-of-life between patients submitted to septoplasty with bilateral outfracture of the inferior turbinate under sedation and local anesthesia in a tertiary hospital and to assess possible clinical-epidemiological variables associated with functional outcome. Fifty-two patients consecutively submitted to septoplasty with bilateral outfracture of the inferior turbinate for treatment of nasal obstruction filled in forms regarding clinical and epidemiological information during enrollment and had their symptom objectively quantified using the Nose Obstruction Symptom Evaluation (NOSE) scale preoperatively and one and three months after the procedure. Statistical analysis aimed to determine overall and stratified surgical outcomes and to investigate correlations between the clinical-epidemiological variables with the scores obtained. Statistically significant improvement in the preoperative NOSE questionnaire compared to the scores obtained three months after surgery was demonstrated (p0.05). Gender, age, history of rhinitis and presence of pulmonary comorbidity did not influence significantly surgical outcomes (p>0.05). Smokers presented greater reduction in NOSE scores during the study (p=0.043, U-Mann-Whitney). Septoplasty with bilateral outfracture of the inferior turbinate has proven to significantly improve disease-specific quality-of-life and this favorable outcome seems to occur precociously.

    In order to perform finite element (FE) analyses of patient-specific abdominal aortic aneurysms, geometries derived from medical images must be meshed with suitable elements. We propose a semi-automatic method for generating conforming hexahedral meshes directly from contours segmented from medical images. Magnetic resonance images are generated using a protocol developed to give the abdominal aorta high contrast against the surrounding soft tissue. These data allow us to distinguish between the different structures of interest. We build novel quadrilateral meshes for each surface of the sectioned geometry and generate conforming hexahedral meshes by combining the quadrilateral meshes. The three-layered morphology of both the arterial wall and thrombus is incorporated using parameters determined from experiments. We demonstrate the quality of our patient-specific meshes using the element Scaled Jacobian. The method efficiently generates high-quality elements suitable for FE analysis, even in the bifurcation region of the aorta into the iliac arteries. For example, hexahedral meshes of up to 125,000 elements are generated in less than 130 s, with 94.8 % of elements well suited for FE analysis. We provide novel input for simulations by independently meshing both the arterial wall and intraluminal thrombus of the aneurysm, and their respective layered morphologies.

    Health-related quality of life (HR-QOL) in patients with celiac disease is reduced compared to the general population. We investigated the association between HR-QOL and clinical, laboratory findings using the previously validated CD-QOL (celiac disease-specific quality of life) instrument in patients with celiac disease. To our knowledge, no study has previously explored the relationship between HR-QOL and clinical, laboratory parameters in celiac patients. Patients who received care at the Allegheny Health Network Celiac Center, Pittsburgh, PA were asked to complete the CD-QOL questionnaire. A cross sectional study with predetermined clinical and laboratory parameters was performed. Data collected included IgA anti-tissue transglutaminase (tTG) antibody titers, iron studies, calcium, vitamin A, B12, 25 OH vitamin D, and E levels. Correlation between clinical findings and CD-QOL was also assessed. Seventy-eight out of 124 patients who completed the questionnaire was included in the analysis. Patients with concomitant irritable bowel syndrome (IBS) had significantly reduced HR-QOL with CD-QOL score of 52.4 ± 11.3 vs. 44.6 ± 12.9 in those without IBS (p = .009). There was no difference in HR-QOL in relation to IgA tTG titers or vitamin D levels. Of note, there was a trend towards correlation between higher level of vitamin E and better QOL (r = -0.236, p = .074). Celiac patients with concomitant IBS have reduced HR-QOL. There was no statistically significant association between HR-QOL and laboratory parameters or levels of micronutrients.

    Biological indicators are widely used to monitor genotic compounds and air quality in urban environments. Parmotrema tinctorum and Teloschistes exilis have been used to verify the presence of pollutants and analyze morphophysiological alterations in the thallus of species caused by their action. Species were exposed for seven months, in an urban area, in southern Brazil. Mutagenicity and cytotoxicity of PM10 organic extracts were assessed in the Salmonella/microsome assay at two stations. High concentrations of S, Pb, Cr, Zn and Hg were registered in the last period of exposure and more significant morphophysiological damages were verified in the lichens. Generally a higher mutagenic activity is observed in organic extracts of airborne particulate matter during the first months and in the third period of exposure of lichens. In addition, nitro compounds was detected through nitro-sensitive strains. Lichens and mutagenic biomarkers enabled the evaluation of air quality and the presence of environmentally-aggressive compounds. Copyright © 2011. Published by Elsevier Ltd.

    In view of understanding colour instability of pasteurised orange juice during storage, to the best of our knowledge, this study reports for the first time in a systematic and quantitative way on a range of changes in specific quality parameters as a function of time and as well as temperature (20-42 °C). A zero-order (°Brix, fructose, glucose), a first-order (vitamin C), a second-order (sucrose) and a fractional conversion model (oxygen) were selected to model the evolution of the parameters between parentheses. Activation energies ranged from 22 to 136 kJ mol(-1), HMF formation being the most temperature sensitive. High correlations were found between sugars, ascorbic acid, their degradation products (furfural and HMF) and total colour difference (ΔE(∗)). Based on PLS regression, the importance of the quality parameters for colour degradation was ranked relatively among each other: the acid-catalysed degradation of sugars and ascorbic acid degradation reactions appeared to be important for browning development in pasteurised orange juice during ambient storage.

    The dosimetric aspects of radiation therapy treatment plan quality are usually evaluated and reported with dose volume histogram (DVH) endpoints. For clinical practicality, a small number of representative quantities derived from the DVH are often used as dose endpoints to summarize the plan quality. National guidelines on reference values for such quantities for some standard treatment approaches are often used as acceptance criteria to trigger treatment plan review. On the other hand, treatment prescription and planning approaches specific to each institution warrants the need to report plan quality in terms of practice consistency and with respect to institution-specific experience. The purpose of this study is to investigate and develop a systematic approach to record and characterize the institution-specific plan experience and use such information to guide the design of plan quality criteria. In the clinical setting, this approach will assist in (1) improving overall plan quality and consistency and (2) detecting abnormal plan behavior for retrospective analysis. The authors propose a self-evolving methodology and have developed an in-house prototype software suite that (1) extracts the dose endpoints from a treatment plan and evaluates them against both national standard and institution-specific criteria and (2) evolves the statistics for the dose endpoints and updates institution-specific criteria. The validity of the proposed methodology was demonstrated with a database of prostate stereotactic body radiotherapy cases. As more data sets are accumulated, the evolving institution-specific criteria can serve as a reliable and stable consistency measure for plan quality and reveals the potential use of the "tighter" criteria than national standards or projected criteria, leading to practice that may push to shrink the gap between plans deemed acceptable and the underlying unknown optimality. The authors have developed a rationale to improve plan quality and

    Clinard, Mark S.

    2004-08-01

    Specification, verification, and maintenance of image quality over the lifecycle of an operational airborne SAR begin with the specification for the system itself. Verification of image quality-oriented specification compliance can be enhanced by including a specification requirement that a vendor provide appropriate imagery at the various phases of the system life cycle. The nature and content of the imagery appropriate for each stage of the process depends on the nature of the test, the economics of collection, and the availability of techniques to extract the desired information from the data. At the earliest lifecycle stages, Concept and Technology Development (CTD) and System Development and Demonstration (SDD), the test set could include simulated imagery to demonstrate the mathematical and engineering concepts being implemented thus allowing demonstration of compliance, in part, through simulation. For Initial Operational Test and Evaluation (IOT&E), imagery collected from precisely instrumented test ranges and targets of opportunity consisting of a priori or a posteriori ground-truthed cultural and natural features are of value to the analysis of product quality compliance. Regular monitoring of image quality is possible using operational imagery and automated metrics; more precise measurements can be performed with imagery of instrumented scenes, when available. A survey of image quality measurement techniques is presented along with a discussion of the challenges of managing an airborne SAR program with the scarce resources of time, money, and ground-truthed data. Recommendations are provided that should allow an improvement in the product quality specification and maintenance process with a minimal increase in resource demands on the customer, the vendor, the operational personnel, and the asset itself.

    The 12-item Stroke-Specific Quality of Life Scale (SSQOL), a shortened version of the original SSQOL, was developed to be an efficient and valid outcome in stroke research. We aimed to assess the validity of this scale in a biethnic ischemic stroke population. Patients with validated ischemic stroke who completed the original 49-item SSQOL at 90 days poststroke were identified from a population-based study, the Brain Attack Surveillance in Corpus Christi Project. Cronbach's α was used to assess the internal consistency of the scales. Intraclass correlation coefficients and linear regression were used to assess agreement between the 2 scales. The study cohort comprised 45 patients with ischemic stroke, 56% female and 51% Mexican American, with a mean age of 66.0±11.3 years. The mean score for the 49-item scale was 3.33±0.84, compared with 3.31±0.95 for the 12-item scale. Internal consistency was 0.96 for the 49-item scale and 0.88 for the 12-item scale. The 2 scales were highly correlated (intraclass correlation coefficient, 0.98; R2=0.97). This study in patients with ischemic stroke from diverse racial/ethnic backgrounds found that the more efficient 12-item SSQOL is a valid alternative to the full 49-item SSQOL for the assessment of health-related quality of life.

    Full Text Available Abstract Background SPARCLE is a nine-centre European epidemiological research study examining the relationship of participation and quality of life to impairment and environment (physical, social and attitudinal in 8–12 year old children with cerebral palsy. Concepts are adopted from the International Classification of Functioning, Disability and Health which bridges the medical and social models of disability. Methods/Design A cross sectional study of children with cerebral palsy sampled from total population databases in 9 European regions. Children were visited by research associates in each country who had been trained together. The main instruments used were KIDSCREEN, Life-H, Strength and Difficulties Questionnaire, Parenting Stress Index. A measure of environment was developed within the study. All instruments were translated according to international guidelines. The potential for bias due to non response and missing data will be examined. After initial analysis using multivariate regression of how the data captured by each instrument relate to impairment and socio-economic characteristics, relationships between the latent traits captured by the instruments will then be analysed using structural equation modelling. Discussion This study is original in its methods by directly engaging children themselves, ensuring those with learning or communication difficulty are not excluded, and by studying in quantitative terms the crucial outcomes of participation and quality of life. Specification and publication of this protocol prior to analysis, which is not common in epidemiology but well established for randomised controlled trials and systematic reviews, should avoid the pitfalls of data dredging and post hoc analyses.

  13. External quality assessment of tumour marker analysis: state of the art and consequences for estimating diagnostic sensitivity and specificity

    Full Text Available This review shows the current analytical quality for the following analytes used as tumour markers in the external quality assessment (EQA-programmes of Instand e.V., a national EQA-organiser in Germany: Corticotropin (ACTH, growth hormone (GH, hGH, prolactin (PRL, chorionic gonadotropin (CG, hCG, calcitonin (CT, hCT, thyroglobulin (Tg, carcinoembryonic antigen (CEA, CA-Antigens 125, 72-4, 15-3 and 19-9, alpha foetoprotein (AFP and prostate-specific antigen (PSA. The results from the participants show a large variation in the precision of the methods used as well as in the comparability of results between methods for the same analyte. In general, the hormones used as tumour markers show better performance than the "CA-markers", which are often inadequately standardised and defined. In the case of one CA-marker (CA 72-4/TAG 72-4, the differences between the lowest kit median concentration and highest kit median concentration for one sample pair were 440% and 580%. The corresponding figures for ACTH were 123% and 156% and for CEA 180% and 184%. The classical tumour markers such as carcinoembryonic antigen (CEA and alpha foetoprotein (AFP performed markedly better than the CA-markers and PSA with regards to both inter- and intra-method comparability. The inter-laboratory precision for a given kit and marker was acceptable in many cases. The results show that only results from the same kit/method for each tumour marker can be used for cumulative or time-dependent comparison of results - for example pre-operative and post-operative follow up. In the case of prostate specific antigen (PSA, the kits used for free and total PSA must come from the same producer, if the generally accepted ratios are to have any diagnostic value. The need for kit- and laboratory-specific reference ranges and cut-off values for setting diagnostic specificity and sensitivity is highlighted from the EQA-results. The situation for inter-method comparability for the CA

    The Medical Subject Headings (MeSH) is the National Library of Medicine (NLM) controlled vocabulary for indexing articles. Inaccuracies in the MeSH thesaurus have been reported for several areas including pharmacy. To assess the quality of pharmacy-specific MeSH assignment to articles indexed in pharmacy journals. The 10 journals containing the highest number of articles published in 2012 indexed under the MeSH 'Pharmacists' were identified. All articles published over a 5-year period (2008-2012) in the 10 previously selected journals were retrieved from PubMed. MeSH terms used to index these articles were extracted and pharmacy-specific MeSH terms were identified. The frequency of use of pharmacy-specific MeSH terms was calculated across journals. A total of 6989 articles were retrieved from the 10 pharmacy journals, of which 328 (4.7%) were articles not fully indexed and therefore did not contain any MeSH terms assigned. Among the 6661 articles fully indexed, the mean number of MeSH terms was 10.1 (SD = 4.0), being 1.0 (SD = 1.3) considered as Major MeSH. Both values significantly varied across journals. The mean number of pharmacy-specific MeSH terms per article was 0.9 (SD = 1.2). A total of 3490 (52.4%) of the 6661 articles were indexed in pharmacy journals without a single pharmacy-specific MeSH. Of the total 67193 MeSH terms assigned to articles, on average 10.5% (SD = 13.9) were pharmacy-specific MeSH. A statistically significant different pattern of pharmacy-specific MeSH assignment was identified across journals (Kruskal-Wallis P journals can be improved to further enhance evidence gathering in pharmacy. Over half of the articles published in the top-10 journals publishing pharmacy literature were indexed without a single pharmacy-specific MeSH. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available ISO 9001 and ISO 14001 certifications has grown spectacularly all over the world in recent years, even though a certain saturation has been detected in some countries. On the one hand this paper aims to analyze the world wide diffusion process of these two standards, using data provided by the ISO itself by a diffusion model based on the logistic curve, that fits quite well to explain the growth of certifications. On the other hand, the paper aims to analyze the case of Spain, one of the countries with a bigger ISO 9001 and ISO 14001 certification's intensity impact, as well as the case of Serbia, a country where ISO 9001 certification is growing more and more.

    Position-specific isotope effects (PSIEs) have been measured by isotope ratio monitoring (13)C nuclear magnetic resonance spectrometry during the evaporation of 10 liquids of different polarities under 4 evaporation modes (passive evaporation, air-vented evaporation, low pressure evaporation, distillation). The observed effects are used to assess the validity of the Craig-Gordon isotope model for organic liquids. For seven liquids the overall isotope effect (IE) includes a vapor-liquid contribution that is strongly position-specific in polar compounds but less so in apolar compounds and a diffusive IE that is not position-specific, except in the alcohols, ethanol and propan-1-ol. The diffusive IE is diminished under forced evaporation. The position-specific isotope pattern created by liquid-vapor IEs is manifest in five liquids, which have an air-side limitation for volatilization. For the alcohols, undefined processes in the liquid phase create additional PSIEs. Three other liquids with limitations on the liquid side have a lower, highly position-specific, bulk diffusive IE. It is concluded that evaporation of organic pollutants creates unique position-specific isotope patterns that may be used to assess the progress of remediation or natural attenuation of pollution and that the Craig-Gordon isotope model is valid for the volatilization of nonpolar organic liquids with air-side limitation of the volatilization rate.

    Full Text Available Abstract Background and object There was no Chinese questionnaire to evaluate the health-related quality of life (HRQoL in patients with hemifacial spasm (HFS. In this study, we aimed to validate a new disease-specific HRQoL scale for HFS (HFS-36 in Chinese version, and compared it to SF-36, a generic HRQoL scale. Patients and Methods The HFS-36 Chinese version was modified from English version of HFS-30, including subscales of mobility, activities of daily living (ADL, emotional well-being, stigma, social support, cognition, bodily discomfort, and communication. All the items were scored on the 5-point scales, ranging from 0(never to 4(always. Patients with HFS were asked to answer HFS-36 and SF-36 questionnaires on the same day before and 6-8 weeks after Botulinum toxin (BTX injections, respectively. The reliability and validity of HFS-36 scale were evaluated statistically. Results Totally, 103 patients (68 females; 35 males were recruited in this study, with a mean age of 57.6 ± 11.5 years and a mean duration of HFS for 7.6 ± 5.8 years. The intra-class correlation (ICC and Cronbach's α were over 0.7 in the majority of items. HFS-36 showed a good correlation to HFS severity before BTX treatment and a significant improvement of subscale scoring after BTX treatment. HFS-36 also had a significant correlation to the mental health of SF-36. Conclusions The Chinese version of HFS-36 demonstrated a good reliability and validity in subscales of motility, ADL, emotion well-being, stigma and bodily discomfort. The HRQoL was significantly improved after BTX treatment assessed by HFS-36 or SF-36. Compared to SF-36, HFS-36 scale was more sensitive and specific to evaluate the HRQoL in HFS.

    used to investigate the effects of the various solar generation scenarios given emissions projections that account for changing regulatory environment, economic and population growth, and technological change. The results will help to quantify the potential air quality benefits of promotion of solar electricity generation in regions containing high penetration of coal-fired power generation. Note current national solar incentives that are based only on solar generation capacity. Further investigation of changes to regional climate due to emission reductions of aerosols and relevant precursors will provide insight into the environmental effects that may occur if solar power generation becomes widespread.

    Full Text Available In cloud computing environments, context information is continuously created by context providers and consumed by the applications on mobile devices. An important characteristic of cloud - based context aware services is meeting the service level agreements (SLAs to deliver a certain quality of service (Qos , s uch as guarantees on response time or price. The response time to a request of context - aware software is affected by loading extensive context data from multiple resources on the chosen server. Therefore, the speed of such software would be decreased durin g execution time. Hence, proper scheduling of such services is indispensable because the customers are faced with time constraints. In this research, a new schedul ing algorithm for context aware services is proposed which is based on classifying similar co ntext consumers and dynamically scoring the requests to improve the performance of the server hosting highly - requested context - aware software while reducing costs of cloud provider. The approach is evaluated via simulation and comparison with gi - FIFO sched uling algorithm. Experimental results demonstrate the efficiency of the proposed app roach

    Background Patient-reported disease perceptions are important components to be considered within a holistic model of quality of care. Gender may have an influence on these perceptions. We aimed to explore gender-specific concerns of patients included in a national bilingual inflammatory bowel disease cohort. Methods Following a qualitative study, we built a questionnaire comprising 37 items of concern. Answers were collected on a visual analog scale ranging from 0 to 100. Principal axis factor analysis was used to explore concern domains. Linear multiple regressions were conducted to assess associations with patient characteristics. Results Of 1102 patients who replied to the survey, 54% were female and 54% had Crohn’s disease. We identified six domains of concern: socialization and stigmatization, disease-related constraints and uncertainty, symptoms and their impact on body and mind, loss of body control (including sexuality), disease transmission, and long-term impact of the disease. Cancer concerns were among the highest scored by all patients (median 61.8). Severity of symptoms was the only factor associated with concerns, unrelated to dimension and gender (p40 years decreased disease-related constraints and uncertainty concerns, and being at home or unemployed increased them. Treatments were associated with increased socialization and stigmatization and with increased disease-related constraints and uncertainty concerns in men. Overall, psychosomatic characteristics were highly associated with concerns for both men and women. Depending on the concern dimensions, increased levels of concern were associated with the highest signs of anxiety in women or depression in men, as well as lower health-related quality of life in men. Conclusions Patients have numerous concerns related to their illness that need to be reassessed regularly. Concerns differ between men and women, suggesting that information and communication about the disease should take gender

    Full Text Available Objectives: To assess health-related quality of life (HRQL in patients with suspected heart failure (HF and to explore discriminate properties of the tools, two generic questionnaires, Short Form 36 (SF-36 and EuroQol 5D (EQ-5D and one specific, the Minnesota Living with Heart Failure questionnaire (MLHF-Q HRQL were employed and compared with New York Heart Association (NYHA functional class. Method: All patients with symptoms suggestive of heart failure referred to University Hospital, Nottingham, between June 2002 and March 2003. Confirmation of left ventricular systolic dysfunction carried out by echocardiography. Main Results: 223 patients (median age=74 were referred. HF was confirmed in 81. Lower HRQL scores were found in older patients (SF-36 and EQ-5D: P30 (P= ns; P<0.05; P= ns respectively. Among those with confirmed heart failure, lower mean scores were found in both subscales of SF-36, four of six subscales in EQ-5D and all MLHF-Q subscales, but these were not statistically significant. SF-36 Mental Component Score (MCS and the emotional subscale of MLHF-Q were more sensitive to depressive disorders than EQ-5D ((P< 0.001; p<0.001; and P< 0.05 respectively. Regression analysis indicated that only SF-36 Physical Component Score (PCS was able to differentiate significantly between NYHA functional classes (P< 0.01. The validity of MLHF-Q was confirmed by correlation with various subclasses in other HRQL measures (P< 0.001 and known group analysis with NYHA functional class (P< 0.001 in both physical and emotional subscales. Conclusion: The specific HRQL measure, MLHF-Q, was more sensitive to functional status in heart failure but emotional abnormalities and general affections were more readily identified by generic tools. Employing both generic and specific HRQL instruments seems necessary in suspected and confirmed heart failure. MLHF-Q showed appropriate construct validity in this sample.

    It is one of the important strategies in the new period of national poverty alleviation and development to maintain the basic balance between the ecological environment and economic development, and to promote the coordinated sustainable development of economy and ecological environment. Taking six contiguous special poverty-stricken areas as the study areas, a coupling coordination evaluation method between eco-environment quality and economic development level in contiguous special poverty-stricken areas was explored in this paper. The region' s ecological poverty index system was proposed based on the natural attribute of ecological environment, and the ecological environment quality evaluation method was built up by using AHP weighting method, followed by the design of the coupling coordination evaluation method between the ecological environment indices and the county economic poverty comprehensive indices. The coupling coordination degrees were calculated and their spatial representation differentiations were analyzed respectively at district, province, city, and county scales. Results showed that approximately half of the counties in the study areas achieved the harmoniously coordinated development. However, the ecological environmental quality and the economic development in most counties could not be synchronized, where mountains, rivers and other geographic features existed roughly as a dividing line of the coordinated development types. The phenomena of dislocation between the ecological environment and economic development in state-level poor counties were more serious than those of local poor counties.

    2009-10-01

    Full Text Available Abstract Background Disease-specific quality of life (QoL measures have enhanced the capacity of outcome measures to evaluate subtle changes and differences between groups. However, when the specific disease is rare, the cohort of patients is small and international collaboration is often necessary to accomplish meaningful research. As many of the QoL measures have been developed in North American English, they require translation to ensure their usefulness in a multi-cultural and/or international society. Published guidelines provide formal methods to achieve cross-culturally comparable versions of a QoL tool. However, these guidelines describe a rigorous process that is not always feasible, particularly in rare disease groups. The objective of this manuscript is to describe the process that was developed to achieve accurate cross-cultural translations of a disease-specific QoL measure, to overcome the challenges of a small sample size, i.e. children with a rare disorder. Procedure A measurement study was conducted in the United Kingdom (UK, France, Germany and Uruguay, during which the validated measure was translated into the languages of the respective countries. Results This is a report of a modified, child-centric, cross-cultural translation and adaptation process in which culturally appropriate and methodologically valid translations of a disease-specific QoL measure, the Kids' ITP Tools (KIT, were performed in children with immune thrombocytopenic purpura (ITP. The KIT was translated from North American English into UK English, French, German, and Spanish. Conclusion This study was a successful international collaboration. The modified process through which culturally appropriate and methodologically valid translations of QoL measures may be achieved in a pediatric population with a relatively rare disorder is reported.

    Measuring quality of life (QOL) is fundamental to understanding the impact of disease and treatment on patients' lives. This study aimed to explore QOL in an international sample of adults with congenital heart disease (CHD), the association between patient characteristics and QOL, and international variation in QOL and its relationship to country-specific characteristics. We enrolled 4,028 adults with CHD from 15 countries. QOL was assessed using a linear analog scale (LAS) (0 to 100) and the Satisfaction with Life Scale (SWLS) (5 to 35). Patient characteristics included sex, age, marital status, educational level, employment status, CHD complexity, and patient-reported New York Heart Association (NYHA) functional class. Country-specific characteristics included general happiness and 6 cultural dimensions. Linear mixed models were applied. Median QOL was 80 on the LAS and 27 on the SWLS. Older age, lack of employment, no marriage history, and worse NYHA functional class were associated with lower QOL (p Happiness scores and cultural dimensions were not associated with variation in QOL after adjustment for patient characteristics and explained only an additional 0.1% of the variance above and beyond patient characteristics (p = 0.56). This large-scale, international study found that overall QOL in adults with CHD was generally good. Variation in QOL was related to patient characteristics but not country-specific characteristics. Hence, patients at risk for poorer QOL can be identified using uniform criteria. General principles for designing interventions to improve QOL can be developed.

    2013-02-01

    Co-morbidity of Developmental Coordination Disorder (DCD) in children with specific language impairment (SLI) and the impact of DCD on quality-of-life (QOL) was investigated in 65 5-8 year old children with SLI (43 boys, age 6.8±0.8; 22 girls, age 6.6±0.8). The prevalence of DCD was assessed using DSM-IV-TR criteria (American Psychiatric Association (APA), 2000) operationally defined in the clinical practice guideline (CPG): movement ABC scores below 15th percentile, scores on DCDQ and/or MOQ-T below 15th percentile, absence of medical condition according to paediatric-neurological exam. Quality of life (QOL) was measured with the TNO-AZL-Child-Quality-Of-Life (TACQOL) Questionnaire filled out by parents for the SLI group with and without DCD, and compared to a reference group (N=572; age 6.9±0.9). The TACQOL covers 7 QOL domains: physical, motor, cognitive and social functioning, autonomy, positive and negative moods. Prevalence of DCD in children with SLI was 32.3%. In children with SLI, mean QOL scores were significantly lower in the autonomy, cognitive, social and positive moods domains compared to the reference group. Children with SLI and DCD differed from children with SLI without DCD by significantly lower mean overall-, motor-, autonomy-, and cognitive domain-QOL scores. Clinicians should be aware that about one third of children with SLI can also be diagnosed with DCD. Assessment of QOL is warranted in order to assess which domains are affected in children with SLI with or without DCD.

    Full Text Available The environment and the health of mankind are subject to strong pressures from pollutants. The ambition of a better quality of life is often frustrated by the increase in emissions as a result of the increasing consumption of resources and energy to satisfy the growth of the world’s population and its expectations for socioeconomic development. At times, problems take on a planetary dimension, the best known example being greenhouse gas emission, with the resulting effects of climate change. Pollution highlights our failure to provide adequate education, which is essential if we are to become fully aware of problems and actively seek sustainable solutions. To this end, it is essential to set up an extended environmental and health education program in all communities that will accompany younger generations from the beginning of their education in order to make them conscious players in protecting the environment and their own health. The size of the problems requires that a joint effort be made at an international level in the political realm and in the scientific-cultural realm in order to share experiences and sensitivity and to seek joint solutions. It is necessary to assign an increasingly important role to scientific and technological innovation which, in the last century, from Marconi to Einstein to Fleming, to the most recent innovations in the fields of genomics and microchips, has allowed humanity to achieve a rate of growth of wellbeing never previously seen in its thousands of years of history. This innovation must rationally be entrusted with our expectations to provide a practical solution to the problems of pollution that threaten our everyday lives and the survival of the planet. This text discusses the types of progress most eagerly awaited in the fields of water supply, wastewater treatment, atmospheric pollution and waste disposal.

    Primary biliary cirrhosis and Primary sclerosing cholangitis are autoimmune cholestatic liver diseases sharing a lot in common, including a significant impairment of patients' health-related quality of life HRQoL HRQoL in PBC is assessed with disease-specific PBC-40 and PBC-27 questionnaires. A PSC-specific questionnaire has not been developed. Neither PBC-40 nor PBC-27s applicability for PSC has been evaluated. We applied these three questionnaires for HRQoL assessment in a large homogenous cohort of PSC patients. This cross-sectional study enrolled 102 Caucasian PSCs and 53 matched healthy controls and measured HRQoL using generic SF-36, and disease-specific (PBC-40/PBC-27) questionnaires. (i) SF-36. Most SF-36 domains were significantly lower in PSCs than controls. Physical Functioning and Mental Component Summary scores were significantly lower in female patients and correlated negatively with age but not with concurrent inflammatory bowel disease. Cirrhosis was associated with lower Physical Functioning, Role Physical, General Health, Vitality and Physical Component Summary. (ii) PBC-40 and PBC-27. Both tools showed similar HRQoL impairment scoring. Fatigue and Cognitive were impaired in female patients. Several correlations existed between HRQoL and laboratory parameters, including cholestatic tests and Itch. Cirrhosis correlated with Other symptoms and Fatigue PBC-40. (iii) PBC-40 vs PBC-27. Strong correlations among most domains of both questionnaires were seen, as well as between (iv) SF-36 vs PBC-40 or SF-36 vs PBC-27. This is the first study directly comparing PBC-40, PBC-27 and SF-36 in PSC. PSC patients, especially females, show HRQoL impairment. PBC-40 and PBC-27 questionnaires could be of potential use for HRQoL assessment in PSC. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Background: Our study was part of the large European project ISAFRUIT aiming to reveal the biological explanations for the epidemiologically well-established health effects of fruits. The objective was to identify effects of apple and apple product consumption on the composition of the cecal...... study (14 weeks), while no effects of apple juice, puree or pomace on microbial composition in cecum were observed. Administration of either 0.33 or 3.3% apple pectin in the diet resulted in considerable changes in the DGGE profiles. A 2-fold increase in the activity of beta-glucuronidase was observed......-glucuronidase producing Clostridiales, and decreases the population of specific species within the Bacteroidetes group in the rat gut. Similar changes were not caused by consumption of whole apples, apple juice, puree or pomace....
