The Sacramento-San Joaquin Delta, the landward reach of the San Francisco Estuary, provides habitat for threatened delta smelt, endangered winter-run Chinook salmon, and other species of concern. It is also the location of huge freshwater diversion facilities that entrain large numbers of fish. Reducing the entrainment of listed fishes into these facilities has required curtailment of pumping, reducing the reliability of water deliveries. We reviewed the first 5 years (2001-2005) of the Environmental Water Account (EWA), a program instituted to resolve conflicts between protecting listed fishes and providing a reliable water supply. The EWA provided fishery agencies with control over 0.2-0.4 km3 of water to be used for fish protection at no cost to users of exported water, and fish agencies guaranteed no disruption of water supply for fish protection. The EWA was successful in reducing uncertainty in water supply; however, its contribution to the recovery of listed fishes was unclear. We estimated the effectiveness of the EWA to be modest, increasing the survival of winter-run Chinook salmon by 0-6% (dependent on prescreen mortality), adult delta smelt by 0-1%, and juvenile delta smelt by 2-4%. Allocating EWA water for a single life stage of one species could provide larger gains in survival. An optimally allocated EWA of equal size to the median of the first 5 years could increase abundance of juvenile delta smelt up to 7% in the springs of dry years. If the EWA is to become a long-term program, estimates of efficacy should be refined. If the program is to be held accountable for quantitative increases in fish populations, it will be necessary to integrate scientific, possibly experimental, approaches. ?? 2008 Springer Science+Business Media, LLC.

The sensitivity of the evanescent wave absorption sensor is always a hot topic which has been attracted researchers' discussion. It is still a challenge for developing the effective sensor to sensitively detect some biochemical molecules solution in a simple and low-cost way. In this paper, an evanescent wave absorption (EWA) sensor has been presented based on the U-bent multimode fiber coated with tungsten disulfide (WS2) film and in-situ growth of gold nanoparticles (AuNPs) for the detection of ethanol solution and sodium chloride (NaCl) solution. Benefitted from the effective light coupling produced between U-bent probe and AuNPs, we attained the optimal size of the AuNPs by changing the reaction time between WS2 and tetrachloroauric acid (HAuCl4). With the AuNPs/WS2@U-bent optical fiber, we discussed the behaviors of EWA sensor, such as sensitivity, reproducibility, fast response-recovery time and stability. The sensitivity (△A/△C) of the proposed AuNPs/WS2@U-bent optical fiber EWA sensor is 0.65 for the detection of the ethanol solution. Besides, the AuNPs/WS2@U-bent optical fiber EWA sensor exhibits high sensitivity in detection of the sodium chloride (NaCl), which can reach 1.5 when the proposed sensor was immersed into NaCl solution. Our work demonstrates that the U-bent optical fiber EWA sensor may have promising applications in testing the solution of concentration.

In gamma camera imaging, scattered radiation is one of big factors to decrease image contrast. Simply, scatter suppression makes signal to noise ratio larger, but it makes statistics error because of radionuclide injection limit to the human body. EWA is a new method that suppresses scattered radiation and improves image contrast. In this article, WAM which is commercialized EWA method by Siemens Gammasonics Inc. is presented. (author)

Swimming Against the Current: A Qualitative Review of the Work Experiences and Adaptations made by Employees with Arthritis.

Purc-Stephenson, R J; Dostie, Jessica; Smith, Hailey J

2018-01-30

To describe the experiences and strategies of employees with arthritis (EwA) to maintain employment and to use this information to build a conceptual model. We conducted a systematic review of qualitative studies that examined the work experiences of EwA. Published studies on arthritis and employment were searched from electronic databases (1980-2017) and bibliographical reviews of relevant studies. We used meta-ethnography to synthesize the findings. We reviewed 17 studies reporting on the experiences of 873 employees. We identified 11 main themes that highlight common issues experienced by EwA, and grouped these into four higher-order categories: nature of the disease (emotional issues, cognitive struggles, physical symptoms), intrapersonal issues (personal meaning of work, preserving a work identity), interpersonal issues (managing disclosure, gaining co-worker support, organizational culture issues), and work-sustainability strategies (making personal adjustments, using social support, using workplace accommodations). Using these themes, we developed the Job Sustainability Model to illustrate how disease, personal, and work-related factors interact to influence what type of coping behaviors are used and when. Initially, EwA rely on making personal adjustments, using social support, and medical intervention. However, when these coping behaviors fail to be effective, they draw upon workplace accommodations and resources. Arthritis disrupts an employee's work life by impairing his or her capacity to be a productive worker. Our results highlight how EwA make strategic adaptations to maintain a productive work life for as long as possible. The findings of this study have implications for work-related interventions aimed at preserving employment. This article is protected by copyright. All rights reserved.

Late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) using magnitude inversion recovery (IR) or phase sensitive inversion recovery (PSIR) has become clinical standard for assessment of myocardial infarction (MI). However, there is no clinical standard for quantification of MI even though multiple methods have been proposed. Simple thresholds have yielded varying results and advanced algorithms have only been validated in single center studies. Therefore, the aim of this study was to develop an automatic algorithm for MI quantification in IR and PSIR LGE images and to validate the new algorithm experimentally and compare it to expert delineations in multi-center, multi-vendor patient data. The new automatic algorithm, EWA (Expectation Maximization, weighted intensity, a priori information), was implemented using an intensity threshold by Expectation Maximization (EM) and a weighted summation to account for partial volume effects. The EWA algorithm was validated in-vivo against triphenyltetrazolium-chloride (TTC) staining (n = 7 pigs with paired IR and PSIR images) and against ex-vivo high resolution T1-weighted images (n = 23 IR and n = 13 PSIR images). The EWA algorithm was also compared to expert delineation in 124 patients from multi-center, multi-vendor clinical trials 2-6 days following first time ST-elevation myocardial infarction (STEMI) treated with percutaneous coronary intervention (PCI) (n = 124 IR and n = 49 PSIR images). Infarct size by the EWA algorithm in vivo in pigs showed a bias to ex-vivo TTC of -1 ± 4%LVM (R = 0.84) in IR and -2 ± 3%LVM (R = 0.92) in PSIR images and a bias to ex-vivo T1-weighted images of 0 ± 4%LVM (R = 0.94) in IR and 0 ± 5%LVM (R = 0.79) in PSIR images. In multi-center patient studies, infarct size by the EWA algorithm showed a bias to expert delineation of -2 ± 6 %LVM (R = 0.81) in IR images (n = 124) and 0 ± 5%LVM (R = 0.89) in

DNA Methylation Patterns in Cord Blood of Neonates Across Gestational Age: Association With Cell-Type Proportions.

Science.gov (United States)

Braid, Susan M; Okrah, Kwame; Shetty, Amol; Corrada Bravo, Hector

A statistical methodology is available to estimate the proportion of cell types (cellular heterogeneity) in adult whole blood specimens used in epigenome-wide association studies (EWAS). However, there is no methodology to estimate the proportion of cell types in umbilical cord blood (also a heterogeneous tissue) used in EWAS. The objectives of this study were to determine whether differences in DNA methylation (DNAm) patterns in umbilical cord blood are the result of blood cell type proportion changes that typically occur across gestational age and to demonstrate the effect of cell type proportion confounding by comparing preterm infants exposed and not exposed to antenatal steroids. We obtained DNAm profiles of cord blood using the Illumina HumanMethylation27k BeadChip array for 385 neonates from the Boston Birth Cohort. We estimated cell type proportions for six cell types using the deconvolution method developed by . The cell type proportion estimates segregated into two groups that were significantly different by gestational age, indicating that gestational age was associated with cell type proportion. Among infants exposed to antenatal steroids, the number of differentially methylated CpGs dropped from 127 to 1 after controlling for cell type proportion. EWAS utilizing cord blood are confounded by cell type proportion. Careful study design including correction for cell type proportion and interpretation of results of EWAS using cord blood are critical.

Ergonomic analysis in the manual transport of loads: a case study in a cement production company

Directory of Open Access Journals (Sweden)

Jarbas Rocha Martins

2017-03-01

Full Text Available This study aims to analyze the manual transport activity of 50kg bags in a cement production company by means of ergonomic work analysis (EWA, identifying environmental factors and loaders’ working conditions. In order for EWA to take place, photographic records, videos and interviews were performed. It covered aspects related to lifting, transportation and handling of cement bags, as well as observations of loaders’ posture while performing the activity. In this sense, both qualitative and quantitative aspects were taken into account, which were evidenced by the use of instruments for determining the concentration of agents in the environment. In addition, some management tools, such as the cause and effect diagram, and interviews conducted during the field research were used. It was found that the high rate of absenteeism in the activity is related to the strict control of productivity, the excessive lifting and manual transport of weights, and repetitive trunk flexion movements. The results shown by the EWA made it possible to propose preventive measures and some changes in the work environment.

Comparison of projection skills of deterministic ensemble methods using pseudo-simulation data generated from multivariate Gaussian distribution

Science.gov (United States)

Oh, Seok-Geun; Suh, Myoung-Seok

2017-07-01

The projection skills of five ensemble methods were analyzed according to simulation skills, training period, and ensemble members, using 198 sets of pseudo-simulation data (PSD) produced by random number generation assuming the simulated temperature of regional climate models. The PSD sets were classified into 18 categories according to the relative magnitude of bias, variance ratio, and correlation coefficient, where each category had 11 sets (including 1 truth set) with 50 samples. The ensemble methods used were as follows: equal weighted averaging without bias correction (EWA_NBC), EWA with bias correction (EWA_WBC), weighted ensemble averaging based on root mean square errors and correlation (WEA_RAC), WEA based on the Taylor score (WEA_Tay), and multivariate linear regression (Mul_Reg). The projection skills of the ensemble methods improved generally as compared with the best member for each category. However, their projection skills are significantly affected by the simulation skills of the ensemble member. The weighted ensemble methods showed better projection skills than non-weighted methods, in particular, for the PSD categories having systematic biases and various correlation coefficients. The EWA_NBC showed considerably lower projection skills than the other methods, in particular, for the PSD categories with systematic biases. Although Mul_Reg showed relatively good skills, it showed strong sensitivity to the PSD categories, training periods, and number of members. On the other hand, the WEA_Tay and WEA_RAC showed relatively superior skills in both the accuracy and reliability for all the sensitivity experiments. This indicates that WEA_Tay and WEA_RAC are applicable even for simulation data with systematic biases, a short training period, and a small number of ensemble members.

A Proxy Method for Estimation of EE-index using MAGDAS/CPMN Data

Science.gov (United States)

Ueno, T.; Yumoto, K.; Uozumi, T.; Numata, Y.; Group, M.

2008-12-01

EE-index (EDst, EU, and EL) is a new index proposed by Space Environment Research Center, Kyushu University (see Uozumi et al., 2008) to monitor temporal and long-term variations of the equatorial electrojet (EEJ). EU and EL mainly represent the range of EEJ and CEJ (equatorial counter electrojet) components, respectively. The baseline levels of EU and EL are obtained by averaging the H-component magnetic variations observed at the nightside (LT = 18-06) MAGDAS/CPMN stations along the magnetic equator. EDst, defined by Uozumi et al. (2008) fluctuates depending on the number of stations in the nightside sector (LT = 18-06). If the number is few, EDst may include some local fluctuations: the partial ring current component, substorm component and so on. Such local components cause some error in estimating the baseline level of EU or EL. Therefore, we need to use as many stations' data as possible in order to derive EU and EL properly. Pacific region is one of the most difficult areas to measure the magnetic field near the dip equator, because there are few islands. In the present paper, we developed a new method to use the data obtained from Ewa Beach (EWA; G. Lat. = 21.32N, G. Long. = 158.0W, Dip Lat. = 38.03), Hawaii, USA for estimation of EDst. EWA is not the equatorial station, but its nighttime H-component magnetic variations are found to be similar to those of Christmas Island (CXI; G. Lat. = 2.05N, G. Long. = 157.5W, Dip Lat. = 5.24), Kiribati. Data from EWA can be used as a proxy of that from CXI for monitoring temporal and long-term variations of the equatorial electrojet (EEJ) in real time. Acknowledgements: Authors appreciate Prof. Hisashi Utada of Earthquake Research Institute, University of Tokyo for supplying the magnetometer data from Christmas Island, Kiribati. Our deepest gratitude goes to all the members of the MAGDAS/CPMN project for their ceaseless support. Especially, we wish to thank the staffs of the observation stations: Dr. Baylie Damtie

EWAS: Modeling Application for Early Detection of Terrorist Threats

Science.gov (United States)

Qureshi, Pir Abdul Rasool; Memon, Nasrullah; Wiil, Uffe Kock

This paper presents a model and system architecture for an early warning system to detect terrorist threats. The paper discusses the shortcomings of state-of-the-art systems and outlines the functional requirements that must to be met by an ideal system working in the counterterrorism domain. The concept of generation of early warnings to predict terrorist threats is presented. The model relies on data collection from open data sources, information retrieval, information extraction for preparing structured workable data sets from available unstructured data, and finally detailed investigation. The conducted investigation includes social network analysis, investigative data mining, and heuristic rules for the study of complex covert networks for terrorist threat indication. The presented model and system architecture can be used as a core framework for an early warning system.

Jllumina - A comprehensive Java-based API for statistical Illumina Infinium HumanMethylation450 and Infinium MethylationEPIC BeadChip data processing

Directory of Open Access Journals (Sweden)

Almeida Diogo

2016-10-01

Full Text Available Measuring differential methylation of the DNA is the nowadays most common approach to linking epigenetic modifications to diseases (called epigenome-wide association studies, EWAS. For its low cost, its efficiency and easy handling, the Illumina HumanMethylation450 BeadChip and its successor, the Infinium MethylationEPIC BeadChip, is the by far most popular techniques for conduction EWAS in large patient cohorts. Despite the popularity of this chip technology, raw data processing and statistical analysis of the array data remains far from trivial and still lacks dedicated software libraries enabling high quality and statistically sound downstream analyses. As of yet, only R-based solutions are freely available for low-level processing of the Illumina chip data. However, the lack of alternative libraries poses a hurdle for the development of new bioinformatic tools, in particular when it comes to web services or applications where run time and memory consumption matter, or EWAS data analysis is an integrative part of a bigger framework or data analysis pipeline. We have therefore developed and implemented Jllumina, an open-source Java library for raw data manipulation of Illumina Infinium HumanMethylation450 and Infinium MethylationEPIC BeadChip data, supporting the developer with Java functions covering reading and preprocessing the raw data, down to statistical assessment, permutation tests, and identification of differentially methylated loci. Jllumina is fully parallelizable and publicly available at http://dimmer.compbio.sdu.dk/download.html

The European Union's 7th Framework Programme (EU's FP7) project HEALS - Health and Environment-wide Associations based on Large Population Surveys - aims a refinement of the methodology to elucidate the human exposome. Human biomonitoring (HBM) provides a valuable tool for understanding the magnitude of human exposure from all pathways and sources. However, availability of specific biomarkers of exposure (BoE) is limited. The objective was to summarize the availability of BoEs for a broad range of environmental stressors and exposure determinants and corresponding reference and exposure limit values and biomonitoring equivalents useful for unraveling the exposome using the framework of environment-wide association studies (EWAS). In a face-to-face group discussion, scope, content, and structure of the HEALS deliverable "Guidelines for appropriate BoE selection for EWAS studies" were determined. An expert-driven, distributed, narrative review process involving around 30 individuals of the HEALS consortium made it possible to include extensive information targeted towards the specific characteristics of various environmental stressors and exposure determinants. From the resulting 265 page report, targeted information about BoE, corresponding reference values (e.g., 95th percentile or measures of central tendency), exposure limit values (e.g., the German HBM I and II values) and biomonitoring equivalents (BEs) were summarized and updated. 64 individual biological, chemical, physical, psychological and social environmental stressors or exposure determinants were included to fulfil the requirements of EWAS. The list of available BoEs is extensive with a number of 135; however, 12 of the stressors and exposure determinants considered do not leave any measurable specific substance in accessible body specimens. Opportunities to estimate the internal exposure stressors not (yet) detectable in human specimens were discussed. Data about internal exposures are useful to decode

With the help of epigenome-wide association studies (EWAS), increasing knowledge on the role of epigenetic mechanisms such as DNA methylation in disease processes is obtained. In addition, EWAS aid the understanding of behavioral and environmental effects on DNA methylation. In terms of statistical analysis, specific challenges arise from the characteristics of methylation data. First, methylation β-values represent proportions with skewed and heteroscedastic distributions. Thus, traditional modeling strategies assuming a normally distributed response might not be appropriate. Second, recent evidence suggests that not only mean differences but also variability in site-specific DNA methylation associates with diseases, including cancer. The purpose of this study was to compare different modeling strategies for methylation data in terms of model performance and performance of downstream hypothesis tests. Specifically, we used the generalized additive models for location, scale and shape (GAMLSS) framework to compare beta regression with Gaussian regression on raw, binary logit and arcsine square root transformed methylation data, with and without modeling a covariate effect on the scale parameter. Using simulated and real data from a large population-based study and an independent sample of cancer patients and healthy controls, we show that beta regression does not outperform competing strategies in terms of model performance. In addition, Gaussian models for location and scale showed an improved performance as compared to models for location only. The best performance was observed for the Gaussian model on binary logit transformed β-values, referred to as M-values. Our results further suggest that models for location and scale are specifically sensitive towards violations of the distribution assumption and towards outliers in the methylation data. Therefore, a resampling procedure is proposed as a mode of inference and shown to diminish type I error rate in

The collective transportation system is essential to reduce the number of automobiles in the roads. Concerns exist related to quality, comfort and safety of bus driver's workstations. The objective of this study was to improve the driver's workstation in the private collective transportation sector by analyzing ergonomic practices using the Ergonomic Work Analysis (EWA). The EWA was chosen because it seeks to evaluate the labor condition as it relates to the psychophysiological conditions of workers, it complies with regulatory standard 17 (NR17). To identify driver concerns, interviews and questionnaires were administered. The workstation and worker routines were observed. The analysis revealed that the largest number of complaints related to noise, display light and location of the passenger identifier device. Drivers reported discomfort in the knees and lower back. Recommendations were made to improve the workstation and change the routine to minimize the discomfort and ergonomic risk factors.

Effect of Nuclear Reactions on the Properties of Al-Mg-Si Alloys after Long-Time Exploitation in Research Reactors

Effect of fast neutron ($E>$ 0.1~?eV) irradiation on the mechanical properties and fracture morphology of the Al-Mg-Si alloys (PAR-1 and ???-1) after 40 years of exploitation in research nuclear reactors has been studied. Tested specimens were cut from structural elements of reactor EWA ($\\acute{\\rm S}$wierk, Poland). Irradiation induces degradation in mechanical properties, namely yield strength and ultimate strength increase, but elongation reduces. The mechanical property changes are caused by ageing of Al--Mg--Si alloy. During irradiation Si is formed from Al by the Al($n, \\gamma $)Si reaction. The presence of Si might cause strengthening of the Al--Mg--Si alloys by increasing precipitation of Mg$_{2}$Si or pure Si in the Al matrix. Post-irradiation activity studies of EWA reactor structural elements show that the high-activity $^{60}$Co and $^{65}$Zn isotopes have been formed by the nuclear reactions.

Gąsowska’s objective has been to reinstate the good name of her grandfather, Jan Rybak, who was murdered in 1945. According to Gąsowska, the reason for her grandfather’s death was his political activity in PPR (Polish Labourers’ Party and his post-war commitment to the reconstruction of People’s Poland (Polska Rzeczpospolita Ludowa. Gąsowska claims that he was murdered by members of Narodowe Siły Zbrojne (National Armed Forces. Almost 60 years after the death of Jan Rybak, a book was published which presents his activity and death in a different light. The book had been written by one of those regarded by Rybak’s family as his murderers. This “courtroom drama” is situated in the context of the relations between the Rybak family and the local community (the place where Jan Rybak, and most likely also his murderers, were born, as well as the socio-political transformations in the contemporary Poland.   Wywiad z Ewą Gąsowską Ewa Gąsowska opowiada historię swoich dziesięcioletnich zmagań z wymiarem sprawiedliwości.

Work-related musculoskeletal disorders (WRMD) are the result of the combination of different risk factors. They are very common among computer workers, mainly when neck and upper limbs are considered. Forty-two office workers from a public university participated in this study. They were divided into two groups: Symptomatic Subjects (SS, n=20) and Asymptomatic Subjects (AS, n=22), according to the Nordic Musculoskeletal Questionnaire (NMQ). Psychosocial indicators were assessed using the Job Content Questionnaire (JCQ) and Utrecht Work Engagement Scale (UWES). Workplaces were evaluated according to the Ergonomic Workplace Analysis (EWA), proposed by the Finnish Institute of Occupational Health. The NMQ showed higher weekly prevalence of complaints on neck, shoulders and wrist/hands (p=0.00) among SS. The annual prevalence of symptoms on wrist/hands was also higher among SS (p=0.02). The JCQ did not show any difference between groups (p>0.05). Higher proportion of servers with 'high level' of engagement, dedication and absorption, according to UWES, was identified among SS (p<0.01). EWA showed worse scores for 'Work Site', 'Job Content' and 'Repetitiveness of the Work' among SS (p<0.05). Servers are exposed to physical and psychosocial risk factors that can contribute to the development of WRMD. Work conditions need to be change in order to improve musculoskeletal health.

NEpiC: a network-assisted algorithm for epigenetic studies using mean and variance combined signals.

Science.gov (United States)

2016-09-19

DNA methylation plays an important role in many biological processes. Existing epigenome-wide association studies (EWAS) have successfully identified aberrantly methylated genes in many diseases and disorders with most studies focusing on analysing methylation sites one at a time. Incorporating prior biological information such as biological networks has been proven to be powerful in identifying disease-associated genes in both gene expression studies and genome-wide association studies (GWAS) but has been under studied in EWAS. Although recent studies have noticed that there are differences in methylation variation in different groups, only a few existing methods consider variance signals in DNA methylation studies. Here, we present a network-assisted algorithm, NEpiC, that combines both mean and variance signals in searching for differentially methylated sub-networks using the protein-protein interaction (PPI) network. In simulation studies, we demonstrate the power gain from using both the prior biological information and variance signals compared to using either of the two or neither information. Applications to several DNA methylation datasets from the Cancer Genome Atlas (TCGA) project and DNA methylation data on hepatocellular carcinoma (HCC) from the Columbia University Medical Center (CUMC) suggest that the proposed NEpiC algorithm identifies more cancer-related genes and generates better replication results. © The Author(s) 2016.

Narcolepsy with cataplexy, which is a hypersomnia characterized by excessive daytime sleepiness and cataplexy, is a multifactorial disease caused by both genetic and environmental factors. Several genetic factors including HLA-DQB1*06:02 have been identified; however, the disease etiology is still unclear. Epigenetic modifications, such as DNA methylation, have been suggested to play an important role in the pathogenesis of complex diseases. Here, we examined DNA methylation profiles of blood samples from narcolepsy and healthy control individuals and performed an epigenome-wide association study (EWAS) to investigate methylation loci associated with narcolepsy. Moreover, data from the EWAS and a previously performed narcolepsy genome-wide association study were integrated to search for methylation loci with causal links to the disease. We found that (1) genes annotated to the top-ranked differentially methylated positions (DMPs) in narcolepsy were associated with pathways of hormone secretion and monocarboxylic acid metabolism. (2) Top-ranked narcolepsy-associated DMPs were significantly more abundant in non-CpG island regions and more than 95 per cent of such sites were hypomethylated in narcolepsy patients. (3) The integrative analysis identified the CCR3 region where both a single methylation site and multiple single-nucleotide polymorphisms were found to be associated with the disease as a candidate region responsible for narcolepsy. The findings of this study suggest the importance of future replication studies, using methylation technologies with wider genome coverage and/or larger number of samples, to confirm and expand on these results.

SOCIAL PARTICIPATION IN THE ENVIRONMENTAL FLOW ASSESSMENT: THE SÃO FRANCISCO RIVER CASE STUDY

Full Text Available Traditionally, water resource management has been developed using an essentially technical approach. Currently, public opinion on water resource management is formed as a result of growing environmental concerns and social conflicts arising from poorly planned actions. Environmental problems are complex and have multiple dimensions, including social and economic. Therefore, the inclusion of a human dimension in integrated assessment methodologies is required for the introduction of new elements to the water management planning process. Environmental water allocation (EWA is understood as the quantity, quality and distribution of water required for the maintenance of the functions and processes of aquatic ecosystems on which people depend. Within the various holistic assessment methodologies, the Building Block Methodology (BBM was found to be the most suitable, in the Brazilian context, for maintaining and restoring essential elements of the natural flow regime. This article describes the process of social participation in the environmental flow assessment (EFA for the Sao Francisco River, and compares it with some of the lessons learned from EFA in other parts of the world. The process involved multiple stakeholders who have conflicting interests. BBM was used to guide the field interviews, to incorporate the empirical observations by the local population and to guide the methodological procedures of the multidisciplinary team. The results of the study indicate the effectiveness of this holistic approach in organizing the elements to be evaluated. It also facilitated important contributions to the establishment of a dialogue between the actors to achieve a better understanding of the multiple aspects involved in the decisions associated with the EWA.

Osteosarcoma (OS) is an aggressive and highly metastatic form of primary bone cancer affecting young children and adults. Previous studies have shown that hypomethylation of critical genes is driving metastasis. Here, we examine whether hypermethylation treatment can block OS growth and pulmonary metastasis. Human OS cells LM-7 and MG-63 were treated with the ubiquitous methyl donor S-adenosylmethionine (SAM) or its inactive analog S-adenosylhomocystine (SAH) as control. Treatment with SAM resulted in a dose-dependent inhibition of tumor cell proliferation, invasion, cell migration, and cell cycle characteristics. Inoculation of cells treated with 150 μmol/L SAM for 6 days into tibia or via intravenous route into Fox Chase severe combined immune deficient (SCID) mice resulted in the development of significantly smaller skeletal lesions and a marked reduction in pulmonary metastasis as compared to control groups. Epigenome wide association studies (EWAS) showed differential methylation of several genes involved in OS progression and prominent signaling pathways implicated in bone formation, wound healing, and tumor progression in SAM-treated LM-7 cells. Real-time polymerase chain reaction (qPCR) analysis confirmed that SAM treatment blocked the expression of several prometastatic genes and additional genes identified by EWAS analysis. Immunohistochemical analysis of normal human bone and tissue array from OS patients showed significantly high levels of expression of one of the identified gene platelet-derived growth factor alpha (PDGFA). These studies provide a possible mechanism for the role of DNA demethylation in the development and metastasis of OS to provide a rationale for the use of hypermethylation therapy for OS patients and identify new targets for monitoring OS development and progression

Synergistic muscle activation intensifies a woman’s ability to contract the PFM. In some cases, even for continent women, it is not possible to fully contract their PFM without involving the synergistic muscles. The primary aim of this study was to assess the surface electromyographic activity of synergistic muscles to PFM (SPFM during resting and functional PFM activation in postmenopausal women with and without SUI.Materials and methods: This study was a preliminary, prospective, cross-sectional observational study and included volunteers and patients who visited the Department and Clinic of Urology, University Hospital in Wroclaw, Poland. Forty-two patients participated in the study and were screened for eligibility criteria.

The Spanish mysticism in paintings by artists from the Fine Arts Academy in Krakow at the turn of the 21st century

Full Text Available During the last two decades the works of teachers from the Painting Department of the Academy of Fine Arts in Krakow: Grzegorz Bednarski, Katarzyna Makieła-Organisty, Janusz Matuszewski, Mirosław Sikorski, Edyta Sobieraj, Zbigniew Sprycha or Wojciech Szybist reveal traces of inspiration by the Spanish Golden Age. In this respect, paintings by Krakow artists stand out against other works of contemporary art both in Poland and globally. Their art should be discussed in the context of early modern meditatio mortis and tenebristic „baroqueism”, to which the artists themselves readily admit. The point of departure (frequently referred to as homage are mystic visions, portraits by El Greco, Francisco de Zurbarán’s bodegóns or eschatological „death hieroglyphics” by Juan de Valdés Léal. References to works by the Iberian masters are accompanied by links to Carmelite writings or Jesuit mystics. Formal and ideological analysis also allows us to ask a question of the possibility of presenting the „mystic theology” described by St. Theresa of the Infant Jesus, St. John of the Cross or St. Ignatius of Loyola in contemporary religious paintings.

It is worth to emphasize that the authors have derived new formulae for the surface of K-dron using the Laplaceatransform in order to obtain the solution of the boundary-value problem for the partial differential equation describing the vibration of the string. The formula proved by us in this paper is clearer and understandable in view of this structure. The solution obtained in this paper describes in general manner the surface of K-dron and more general surfaces named by us n-K-drons. The formula for the surface of K-dron was derived by the method of Laplacea transform having clear geometrical and physical interpretation because it is presented in linear combination of the equation of planes with the coefficients of directions described by suitable combinations of Heavisides functions. Also wide range and different applications of K-dron are presented.[b]Słowa kluczowe[/b]: K-dron, Laplace’a transform, partial differential of string equation of vibration, initial-boundary value problems

During the last decades there have been many changes in the banking sector organization. It has been also observed the mutual growing of musculoskeletal and mental disorders. This study investigated the workload of bank tellers at a Brazilian public institution. It was performed the Ergonomic Work Analysis (EWA). Three employees participated in this study. During the analysis process, three research instruments were applied: Inventory of Work and Risk of Illness, Yoshitake Fatigue Questionnaire and Nordic Musculoskeletal Questionnaire, beyond the realization of footage recordings and the self-confrontation. The results indicated the existence of an excess of workload on the evaluated workstations, mainly in relation to mental order constraints, that overlaps the physical aspects. Thereby it was found that the employees tend to adopt strategies trying to reduce the impacts of the excess of workload, in order to regulate it.

The increased prevalence of obesity and related comorbidities is a major public health problem. While genetic factors undoubtedly play a role in determining individual susceptibility to weight gain and obesity, the identified genetic variants only explain part of the variation. This has led to growing interest in understanding the potential role of epigenetics as a mediator of gene-environment interactions underlying the development of obesity and its associated comorbidities. Initial evidence in support of a role of epigenetics in obesity and type 2 diabetes mellitus (T2DM) was mainly provided by animal studies, which reported epigenetic changes in key metabolically important tissues following high-fat feeding and epigenetic differences between lean and obese animals and by human studies which showed epigenetic changes in obesity and T2DM candidate genes in obese/diabetic individuals. More recently, advances in epigenetic methodologies and the reduced cost of epigenome-wide association studies (EWAS) have led to a rapid expansion of studies in human populations. These studies have also reported epigenetic differences between obese/T2DM adults and healthy controls and epigenetic changes in association with nutritional, weight loss, and exercise interventions. There is also increasing evidence from both human and animal studies that the relationship between perinatal nutritional exposures and later risk of obesity and T2DM may be mediated by epigenetic changes in the offspring. The aim of this review is to summarize the most recent developments in this rapidly moving field, with a particular focus on human EWAS and studies investigating the impact of nutritional and lifestyle factors (both pre- and postnatal) on the epigenome and their relationship to metabolic health outcomes. The difficulties in distinguishing consequence from causality in these studies and the critical role of animal models for testing causal relationships and providing insight into underlying

As the world's population ages, the age-related cognitive decline presents a great challenge to world's healthcare systems. One of the molecular mechanisms implicated in cognitive ageing is DNA methylation, an epigenetic modification known to be a key player in memory formation, maintenance......, and synaptic plasticity. Using the twin design we performed an epigenome-wide association study (EWAS) in a population of 486 middle-aged monozygotic twins (mean age at follow-up 65.9, SD = 6.1) and correlated their blood DNA methylation to their level (cross-sectional analysis) and change in cognitive...... abilities over 10 years (longitudinal analysis). We identified several CpG sites where cross-sectional cognitive functioning was associated with DNA methylation levels.

New insights and updated guidelines for epigenome-wide association studies

Directory of Open Access Journals (Sweden)

Lisa H. Chadwick

2015-01-01

Full Text Available Epigenetic dysregulation in disease is increasingly studied as a potential mediator of pathophysiology. The epigenetic events are believed to occur in somatic cells, but the limited changes of DNA methylation in studies to date indicate that only subsets of the cells tested undergo epigenetic dysregulation. The recognition of this subpopulation effect indicates the need for care in design and execution of epigenome-wide association studies (EWASs, paying particular attention to confounding sources of variability. To maximize the sensitivity of the EWASs, ideally, the cell type mediating the disease should be tested, which is not always practical or ethical in human subjects. The value of using accessible cells as surrogates for the target, disease-mediating cell type has not been rigorously tested to date. In this review, participants in a workshop convened by the National Institutes of Health update EWAS design and execution guidelines to reflect new insights in the field.

Narimoto, Lidiane Regina; Camarotto, João Alberto

2017-01-01

Design in use and inventiveness are key concepts in ergonomics. It is well-known that users design but is not explored in the literature how they manage to do that. This paper aims to contribute to the discussion of how users actually design, by showing a research conducted in sugar cane harvesting in Brazil and in Australia. Through the methodology of the Ergonomic Work Analysis (EWA), the design modifications made by the harvesting teams were identified as well as their elaboration process. Three categories of modifications in machines' design were identified: structural, functional and operational and they were more numerous in Brazilian situations. It is proposed that two theories underlying the theme are intertwined: the instrument-mediated activity approach and the design as bricolage. It is argued that users design through the articulation of: a) the operators' activity, b) the mechanical technicians' inventory to practice bricolage as a way of designing and c) the work organisation and the existence of social spaces of interaction between these two subjects.

The Northwest Passage in the Arctic is a sea rout from Greenland through the straits of the Canadian Arctic to the Bering Strait. The passage can only by navigated during the short polar summer, the rest of the year it is entirely frozen. For many years lands (islands and peninsulas) along it were not accessible from the sea for sampling of lichens and mosses due the ice covering it even in summer or due to serious danger of collision with massive ice pack. In last summers it become available for travel even using small yacht 'Marguerite' with the French-Polish crew (capt. Janusz Kurbiel, Joelle Kurbiel, Maria Olech, Tomasz Kosinski), which crossed the Northern Passage within 28 days, reaching the Bering Strait on 16 September 2012. Samples of lichens and mosses were collected in this expedition from coastal zones of western Greenland, north Canada and Alaska. They were collected in several locations on islands and peninsulas along the rout. After identification of species samples are dried, homogenized and analyzed by means of low background gamma spectrometry in aim of determination of gamma emitters, mostly the {sup 137}Cs, activity.

The first hydrogel for wound dressing processed by radiation was developed in Poland in 1986 by the inventor Janusz M. Rosiak and reached the local market in 1992. Laboratories of developing countries, which face all kinds of restrictions, were seduced by the simplicity of the process and low cost of its raw materials. It was a technological breakthrough due to its painless product characteristics and having improved healing properties such as absorbing a high water capacity, attached to healthy skin, and being easy to remove, plus its intelligent production process combining sterilization and crosslinking in a simultaneous operation. The use of hydrogels as biomaterials has increased recently. Hydrogel wound dressings were prepared using the gamma ray irradiation technique. Radiation was applied as a tool for crosslinking and sterilization of these materials. The hydrogels are composed of poly (N-vinyl-2-pyrrolidone) (PVP), poly (ethylene glycol) (PEG) and agar at radiation doses of 15, 20, 25, 30 kGy. The influence of some process parameters on their properties was investigated by: sterilization, gel fraction, swelling measures and mechanical properties. Hydrogels with less than 20 kGy of radiation were not properly sterilized. The gel fraction and swelling increased with increasing radiation dose due to increased crosslinking density, and at 25kGy, obtained optimum swelling. No significant differences were found for the test of mechanical properties but hydrogel matrices of different doses of gamma radiation. (author)

Full Text Available Barrie Rathbone,1 Janusz Jankowski,2 Michael Rathbone31University Hospitals of Leicester, Leicester, 2Sir James Black Professor Queen Mary University of London, 3St George's University of London, London, United KingdomAbstract: Esophageal cancer is the sixth commonest cause of cancer death worldwide. It predominantly occurs in two histological types, ie, squamous cell carcinoma and adenocarcinoma, each with its own distinct geographical distribution and natural history. The incidence of esophageal adenocarcinoma is rising, as is that of its precursor lesion, Barrett's esophagus, which consists of metaplastic change in the squamous mucosa of the esophagus in response to damage by gastroesophageal reflux disease. The principal risk factors for esophageal cancer are cigarette smoking and alcohol consumption, reflux disease, and obesity. In tumors without local invasion or distant metastases, surgery remains the treatment option of choice, although there are considerable differences of opinion regarding the roles of chemotherapy and radiotherapy. A wide variety of endoscopic treatments are available for dysplastic lesions and palliation. Despite the availability of increasingly complex imaging modalities and expensive and possibly ineffective attempts at screening, the evidence base is conflicted and the prognosis remains poor. However, from a recent large systematic review, three clear recommendations can be made, ie, use of endoscopic resection for high grade dysplasia, use of radiofrequency ablation for residual premalignant lesions, and, finally, prevention of risk factors for cancer, such as smoking, alcohol consumption, and obesity.Keywords: cancer, Barrett's, esophagus, squamous cell carcinoma, adenocarcinoma

Entropy-Weighted Instance Matching Between Different Sourcing Points of Interest

Directory of Open Access Journals (Sweden)

Lin Li

2016-01-01

Full Text Available The crucial problem for integrating geospatial data is finding the corresponding objects (the counterpart from different sources. Most current studies focus on object matching with individual attributes such as spatial, name, or other attributes, which avoids the difficulty of integrating those attributes, but at the cost of an ineffective matching. In this study, we propose an approach for matching instances by integrating heterogeneous attributes with the allocation of suitable attribute weights via information entropy. First, a normalized similarity formula is developed, which can simplify the calculation of spatial attribute similarity. Second, sound-based and word segmentation-based methods are adopted to eliminate the semantic ambiguity when there is a lack of a normative coding standard in geospatial data to express the name attribute. Third, category mapping is established to address the heterogeneity among different classifications. Finally, to address the non-linear characteristic of attribute similarity, the weights of the attributes are calculated by the entropy of the attributes. Experiments demonstrate that the Entropy-Weighted Approach (EWA has good performance both in terms of precision and recall for instance matching from different data sets.

The increased generation of garbage has become a problem in large cities, with greater demand for collection services. The collector is subjected to high workload. This study describes the work in garbage collection service, highlighting the requirements of time, resulting in physical and psychosocial demands to collectors. Ergonomic Work Analysis (EWA) - a method focused on the study of work in real situations was used. Initially, technical visits, global observations and unstructured interviews with different subjects of a garbage collection company were conducted. The following step of the systematic observations was accompanied by interviews conducted during the execution of tasks, inquiring about the actions taken, and also interviews about the actions, but conducted after the development of the tasks, photographic records and audiovisual recordings, of workers from two garbage collection teams. Contradictions between the prescribed work and activities (actual work) were identified, as well as the variability present in this process, and strategies adopted by these workers to regulate the workload. It was concluded that the insufficiency of means and the organizational structure of management ensue a situation where the collection process is maintained at the expense of hyper-requesting these workers, both physically and psychosocially.

Canary seed is an important specialty crop in Canada. The current market for this true cereal (i.e., belonging to the family Poaceae as wheat) is limited to feed for caged birds. However, canary seed holds a promise for many food and industrial applications based on its composition. Three wet milling procedures based on ethanol (E), water (W), and alkaline (A) extractions used in different order were investigated to determine extraction efficiency and purity of starch, protein, oil, and fiber separated from hairless canary seed, a variety developed for human consumption. Highest extraction efficiencies were obtained when canary seed was defatted with ethanol and then extracted with alkali and water (EAW process). Using this process, approximately 92% pure starch, 75% pure protein, and oil were recovered from canary seed groats. The highest purity of protein, however, was obtained when canary seed was fractionated by the EWA process, that is, defatted and then extracted with water followed by alkali. Fiber component separated prior to alkaline extraction contained high amounts of nonfiber components as indicated by its yield. The EAW extraction process seems to be more promising in canary seed fractionation based on recovery and purity of components.

Full Text Available Phantasm of the Righteous and Agnieszka Holland’s film "In Darkness" The text analyses Agnieszka Holland’s film In Darkness against the background of the Polish discourse on the Righteous. The devices of this discourse are reconstructed on the basis of two documentary films: The Righteous by Ryszard Gontarz and Janusz Kidawa (1968 and The Story of the Kowalski by Arkadiusz Gołębiowski and Maciej Pawlicki (2009. The basic devices distinguished in the narrative of the Righteous are the following: 1. a symmetry between the Jewish and Polish suffering 2. lack of Jews’ gratefulness and solidarity (“we demonstrated solidarity as far as the sacrifice of life but they…”; 3. treating the Righteous as pars pro toto of the community (they become the proof of the “national character” of Poles; the motif of “the Righteous-anti-Semite”; 4. a conviction about Polish helplessness; 5. marginalisation of the Polish aggression against Jews (a viewpoint that apparently “the scum is everywhere” and the simultaneously expressed accusations that the victims were involved in the Holocaust themselves. Holland is not aware of the discursive mechanisms accumulating around the undertaken subject or the correlated stakes of the common imagination. Therefore, many fragments of In Darkness easily succumb to being captured by the prevailing, and in fact anti-Semitic, clichés of understanding the history. In effect, the phenomenon of unwanted comeback of phantasms occurs in reference to a narrative developed as an antidote for such.

Ergonomics and risk management in high risk organizations: nuclear power plant operator decision making; A ergonomia e a gestao de risco em organizacoes que lidam com tecnologias perigosas: tomada de decisao de operadores de usinas nucleares

Nuclear power plants are high hazard environments where emergency situations can have devastating effects. The operator crew has the ultimate responsibility to control the energy production process with safety. The outcome of a crisis is consequently dependent on the crew's judgement, decision making and situation awareness. In such way we should know how operators make their decisions in order to develop safety strategies. The aim of this thesis is to examine the cognitive processes through which operators make decisions when dealing with micro incidents during their actual work, and to determine whether they use a naturalistic or normative decision making strategy. That is, do they try to recognize the micro incident as familiar and base decisions on condition-action rules (naturalistic), or do they need to concurrently compare and contrast options before selecting the best possible (normative). The method employed for data collection was the Cognitive Task Analysis (CTA) and Ergonomic Work Analysis (EWA). The main findings of this thesis were that decision making is primarily based on naturalistic strategies, such as condition-action rules and recognition. In new situations rules are created ad hoc. These rules appear derived from experience and training rather than from Standard Operating Procedures and contrast normative competence standards used by nuclear industry. (author)

Epigenetics and cerebral organoids: promising directions in autism spectrum disorders.

Autism spectrum disorders (ASD) affect 1 in 68 children in the US according to the Centers for Disease Control and Prevention (CDC). It is characterized by impairments in social interactions and communication, restrictive and repetitive patterns of behaviors, and interests. Owing to disease complexity, only a limited number of treatment options are available mainly for children that alleviate but do not cure the debilitating symptoms. Studies confirm a genetic link, but environmental factors, such as medications, toxins, and maternal infection during pregnancy, as well as birth complications also play a role. Some studies indicate a set of candidate genes with different DNA methylation profiles in ASD compared to healthy individuals. Thus epigenetic alterations could help bridging the gene-environment gap in deciphering the underlying neurobiology of autism. However, epigenome-wide association studies (EWAS) have mainly included a very limited number of postmortem brain samples. Hence, cellular models mimicking brain development in vitro will be of great importance to study the critical epigenetic alterations and when they might happen. This review will give an overview of the state of the art concerning knowledge on epigenetic changes in autism and how new, cutting edge expertise based on three-dimensional (3D) stem cell technology models (brain organoids) can contribute in elucidating the multiple aspects of disease mechanisms.

The 200-500 mg samples after wet digestion and evaporation were dissolved in glycine solution and after pH adjusting to ca. 4.4 were passed through the column with Lix 64N on Bio Beads SM-1 for isolation of copper traces from the matrix elements. Other cations were selectively eluted with 0.1 mol x 1 -1 (glycine-HNO 3 ) buffer, 1 mol x 1 -1 in NH 4 NO 3 (pH = 3.6). The resin bed with quantitatively retained copper was sealed in the PE bag and irradiated together with Cu standards in EWA reactor using pneumatic tube facility. The activity of the short-lived 66 Cu was measured in samples and standard by gamma-ray spectrometry with Ge(Li) detector. Good accuracy of the method was confirmed by analysis of the following certified reference materials: NBS 1571 Orchad leaves, IAEA H-4 Animal muscle, IAEA V-8 Rye flour, IAEA A-11 milk powder. The detection limit amounted to 0.34 mg/kg, for the sample weight of 500 mg. (author)

This paper introduces the RiskSOAP ('RiskSOAP' is the abbreviation for Risk SituatiOn Awareness Provision.) indicator to measure the capability of a complex socio-technical system to provide its agents with situation awareness (SA) about the presence of its threats and vulnerabilities and enables analysts to assess distributed SA. The RiskSOAP methodology adopts a comparative approach between two design versions of a system differing in the elements and characteristics that can enhance or cause the degradation of the awareness provision capability. The methodology uniquely combines three methods: (1) the STPA hazard analysis, (2) the EWaSAP early warning sign identification approach, and (3) a dissimilarity measure for calculating the distance between binary sets. In this paper, the RiskSOAP methodology was applied to a robotic system and the findings show that the indicator is an objective measure for the system's capability to provide its agents with SA about its threats and vulnerabilities. Practitioner Summary: This paper suggests a novel methodology for assessing distributed situation awareness (DSA) regarding safety issues. Given that systems consist of specifications and components possible to be mapped, the risk SA provision capability (RiskSOAP) methodology demonstrates the feasibility of measuring to what extent systems' elements contribute to the emergence of DSA.

Glioblastoma multiforme cells were cultured on the chorioallantoic membrane of chicken embryo and after 7 days of incubation, were treated with carbon nanoparticles administered in ovo to the tumor. Both types of nanoparticles significantly decreased tumor mass and volume, and vessel area. Quantitative real-time polymerase chain reaction analysis showed downregulated fibroblast growth factor-2 and vascular endothelial growth factor expression at the messenger ribonucleic acid level. The present results demonstrate antiangiogenic activity of carbon nanoparticles, making them potential factors for anticancer therapy.Keywords: cancer, nanoparticle, embryo, angiogenesis, FGF-2, VEGF

Hypertension is an important precursor to the development of CVD, and although detection and treatment rates have improved in recent years in some jurisdictions, effective strategies and policies supporting a shift in distribution of risk factors at the population level remain paramount. Challenges in managing cardiovascular health more effectively include factors at the patient, provider, and system level. Strategies to reduce hypertension and CVD should be population based, incorporate multilevel, multicomponent, and socioenvironmental approaches, and integrate community resources with public health and clinical care. There is an urgent need to improve monitoring and management of risk factors through community-wide, primary care-linked initiatives, increase the evidence base for community-based prevention strategies, further develop and evaluate promising program components, and develop new approaches to support healthy lifestyle behaviors in diverse age, socioeconomic, and ethnocultural groups. Policy and system changes are critical to reduce risk in populations, including legislation and public education to reduce dietary sodium and trans-fatty acids, food pricing policies, and changes to health care delivery systems to explicitly support prevention and management of CVD.Keywords: risk factors, blood pressure determination, community health services, community health planning, public health practice

Patients with anorexia nervosa (AN) are ideally suited to identify differentially methylated genes in response to starvation. We examined high-throughput DNA methylation derived from whole blood of 47 females with AN, 47 lean females without AN and 100 population-based females to compare AN with both controls. To account for different cell type compositions, we applied two reference-free methods (FastLMM-EWASher, RefFreeEWAS) and searched for consensus CpG sites identified by both methods. We used a validation sample of five monozygotic AN-discordant twin pairs. Fifty-one consensus sites were identified in AN vs. lean and 81 in AN vs. population-based comparisons. These sites have not been reported in AN methylation analyses, but for the latter comparison 54/81 sites showed directionally consistent differential methylation effects in the AN-discordant twins. For a single nucleotide polymorphism rs923768 in CSGALNACT1 a nearby site was nominally associated with AN. At the gene level, we confirmed hypermethylated sites at TNXB. We found support for a locus at NR1H3 in the AN vs. lean control comparison, but the methylation direction was opposite to the one previously reported. We confirm genes like TNXB previously described to comprise differentially methylated sites, and highlight further sites that might be specifically involved in AN starvation processes.

Tic disorders are moderately heritable common psychiatric disorders that can be highly troubling, both in childhood and in adulthood. In this study, we report results obtained in the first epigenome-wide association study (EWAS) of tic disorders. The subjects are participants in surveys at the Netherlands Twin Register (NTR) and the NTR biobank project. Tic disorders were measured with a self-report version of the Yale Global Tic Severity Scale Abbreviated version (YGTSS-ABBR), included in the 8th wave NTR data collection (2008). DNA methylation data consisted of 411,169 autosomal methylation sites assessed by the Illumina Infinium HumanMethylation450 BeadChip Kit (HM450k array). Phenotype and DNA methylation data were available in 1,678 subjects (mean age = 41.5). No probes reached genome-wide significance (p tic disorders. The top significantly enriched gene ontology (GO) terms among higher ranking methylation sites included anatomical structure morphogenesis (GO:0009653, p = 4.6 × 10-(15)) developmental process (GO:0032502, p = 2.96 × 10(-12)), and cellular developmental process (GO:0048869, p = 1.96 × 10(-12)). Overall, these results provide a first insight into the epigenetic mechanisms of tic disorders. This first study assesses the role of DNA methylation in tic disorders, and it lays the foundations for future work aiming to unravel the biological mechanisms underlying the architecture of this disorder.

Full Text Available Ewa Markiewicz, Olusola Clement Idowu Research & Development, Hexis Lab, Science Central, The Core, Bath Lane, Newcastle upon Tyne, UK Abstract: Individual responses of human skin to the environmental stress are determined by differences in the anatomy and physiology that are closely linked to the genetic characteristics such as pigmentation. Ethnic skin phenotypes can be distinguished based on defined genotypic traits, structural organization and compartmentalized sensitivity to distinct extrinsic aging factors. These differences are not only responsible for the variation in skin performance after exposure to damaging conditions, but can also affect the mechanisms of drug absorption, sensitization and other longer term effects. The unique characteristics of the individual skin function and, particularly, of the ethnic skin type are currently considered to shape the future of clinical and pharmacologic interventions as a basis for personalized skincare. Individual approaches to skincare render a novel and actively growing area with a range of biomedical and commercial applications within cosmetics industry. In this review, we summarize the aspects of the molecular and clinical manifestations of the environmental stress on human skin and proposed protective mechanisms that are linked to ethnic differences and pathophysiology of extrinsic skin aging. We subsequently discuss the possible applications and translation of this knowledge into personalized skincare.

Rates of SCA diagnoses in infants and children are increasing, and there is a need for specialized interdisciplinary care to address associated risks. The eXtraordinarY Kids Clinic was established to provide comprehensive and experienced care for children and adolescents with SCA, with an interdisciplinary team composed of developmental–behavioral pediatrics, endocrinology, genetic counseling, child psychology, pediatric neuropsychology, speech–language pathology, occupational therapy, nursing, and social work. The clinic model includes an interdisciplinary approach to care, where assessment results by each discipline are integrated to develop unified diagnostic impressions and treatment plans individualized for each patient. Additional objectives of the eXtraordinarY Kids Clinic program include prenatal genetic counseling, research, education, family support, and advocacy. Methods: Satisfaction surveys were distributed to 496 patients, and responses were received from 168 unique patients. Results: Satisfaction with the overall clinic visit was ranked as “very satisfied” in 85%, and as “satisfied” in another 9.8%. Results further demonstrate specific benefits from the clinic experience, the importance of a knowledgeable clinic coordinator, and support the need for similar clinics across the country.

Both endorphins excess and deficiency were postulated. CGRP is probably involved in dopaminergic transmission. The aim of this study was the evaluation of beta-endorphin (BE and CGRP blood concentrations before and after treatment of severe schizophrenia. Methods: Seventy patients treated with various antipsychotics, with severe symptoms of schizophrenia (51 with positive symptoms, 19 with negative symptoms, 15 first-degree relatives, and 44 healthy controls were included in the study. BE and CGRP blood concentrations were measured during patients severe schizophrenia and in their stable mental state after treatment. The results were compared with relatives and controls. Results: BE and CGRP concentrations in patients with negative symptoms were higher than in relatives and in controls. BE levels in patients with positive symptoms were lower than in patients with negative symptoms (P<0.0000 and controls (P<0.0006. No significant changes in CGRP concentration were found in patient samples. CGRP levels in these samples were independent of treatment, but they were significantly higher than in relatives and controls. After the treatment, BE level decreased in patients with negative symptoms (P<0.0001 and increased in patients with positive symptoms (P<0.0000. No differences in BE concentration between patients in stable mental state, their relatives, and controls were found. Conclusion: Effective antipsychotic treatment results in “normalization” of BE level. Specific changes in BE concentration could be involved in dopaminergic transmission and related to some symptoms of schizophrenia. Keywords

Highlights: • Invasive and native algae are a part of a reef assemblage located in an urban area. • Algal nitrogen (N) composition tested if N was enriched from storm-drain outlets. • Elevated N values indicated a mixed, high nutrient environment. • Storm-drains as plausible nitrogenous source was not supported. • Temporal and spatial values indicate algae incorporated terrestrial derived N. -- Abstract: Nitrogen (N) enrichment of tropical reefs can result in the dominance of invasive algae. The invasive alga Acanthophora spicifera and the native alga Laurencia nidifica are part of a diverse reef assemblage in ‘Ewa Beach, O‘ahu. Their N contents and δ 15 N values were investigated to determine if N was enriched and to evaluate potential nitrogenous sources near and removed from storm-drain outlets. δ 15 N values of algae (3.8–17.7‰) were within and above the range for algae around the island (1.9–11.9‰). Elevated algae N isotope values (δ 15 N > +7‰, [N] > 1.6%) and seawater nitrate + nitrite levels (0.59–7.93 μM) indicated a mixed, high nutrient environment. The overlap in δ 15 N values with multiple nitrogenous sources precluded identification. However, spatial and temporal patterns did not support stormwater as the dominant, nitrogenous source. Patterns were congruent with algal incorporation of terrestrial derived N, subjected to a high degree of biogeochemical cycling

An environment-wide association study (EWAS) may be useful to comprehensively test and validate associations between environmental factors and cardiovascular disease (CVD) in an unbiased manner. Data from National Health and Nutrition Examination Survey (1999-2014) were randomly 50:50 spilt into training set and testing set. CVD was ascertained by a self-reported diagnosis of myocardial infarction, coronary heart disease or stroke. We performed multiple linear regression analyses associating 203 environmental factors and 132 clinical phenotypes with CVD in training set (false discovery rate multicollinearity elimination and variable importance ranking. Discriminative power of factors for CVD was calculated by area under the receiver operating characteristic (AUROC). Overall, 43,568 participants with 4084 (9.4%) CVD were included. After adjusting for age, sex, race, body mass index, blood pressure and socio-economic level, we identified 5 environmental variables and 19 clinical phenotypes associated with CVD in training and testing dataset. Top five factors in RF importance ranking were: waist, glucose, uric acid, and red cell distribution width and glycated hemoglobin. AUROC of the RF model was 0.816 (top 5 factors) and 0.819 (full model). Sensitivity analyses reveal no specific moderators of the associations. Our systematic evaluation provides new knowledge on the complex array of environmental correlates of CVD. These identified correlates may serve as a complementary approach to CVD risk assessment. Our findings need to be probed in further observational and interventional studies. Copyright © 2018. Published by Elsevier Ltd.

Objectives: The aim of the study was to compare the effectiveness of multi-layer compression bandaging (MCB and complex decongestive therapy (CDT, and to show that MCB is a cheaper, more accessible and less labor intensive method of treating lymphedema in elderly patients. Patients and methods: The study included 103 patients (85 women and 18 men aged ≥60 years, with unilateral lower limb lymphedema. The subjects were divided into two groups: 50 treated with CDT and 53 with MCB. Pre- and post-treatment BMI, and average and maximum circumference of the edematous extremities were analyzed. Results: Reduction in swelling in both groups was achieved after 15 interventions. Both therapies demonstrated similar efficacy in reducing limb volume and circumference, but MCB showed greater efficacy in reducing the maximum circumference. Conclusion: Compression bandaging is a vital component of CDT. Maximum lymphedema reduction during therapy and maintaining its effect cannot be achieved without it. It also demonstrates its effectiveness as an independent method, which can reduce therapy cost and accessibility. Keywords: lymphedema, elderly, therapy, compression bandaging

Full Text Available Environmental factors such as tobacco smoking may have long-lasting effects on DNA methylation patterns, which might lead to changes in gene expression and in a broader context to the development or progression of various diseases. We conducted an epigenome-wide association study (EWAs comparing current, former and never smokers from 1793 participants of the population-based KORA F4 panel, with replication in 479 participants from the KORA F3 panel, carried out by the 450K BeadChip with genomic DNA obtained from whole blood. We observed wide-spread differences in the degree of site-specific methylation (with p-values ranging from 9.31E-08 to 2.54E-182 as a function of tobacco smoking in each of the 22 autosomes, with the percent of variance explained by smoking ranging from 1.31 to 41.02. Depending on cessation time and pack-years, methylation levels in former smokers were found to be close to the ones seen in never smokers. In addition, methylation-specific protein binding patterns were observed for cg05575921 within AHRR, which had the highest level of detectable changes in DNA methylation associated with tobacco smoking (-24.40% methylation; p = 2.54E-182, suggesting a regulatory role for gene expression. The results of our study confirm the broad effect of tobacco smoking on the human organism, but also show that quitting tobacco smoking presumably allows regaining the DNA methylation state of never smokers.

Genome-wide association studies (GWAS) and linkage analysis has identified many single nucleotide polymorphisms (SNPs) related to disease. There are many unknown SNPs whose minor allele frequencies (MAFs) as low as 0.005 having intermediate effects with odds ratio between 1.5~3.0. Low frequency variants having intermediate effects on disease pathogenesis are believed to have complex interactions with environmental factors called gene-environment interactions (GxE). Hence, we describe a model using 3D Manhattan plot called GxE landscape plot to visualize the association of p-values for gene-environment interactions (GxE). We used the Gene-Environment iNteraction Simulator 2 (GENS2) program to simulate interactions between two genetic loci and one environmental factor in this exercise. The dataset used for training contains disease status, gender, 20 environmental exposures and 100 genotypes for 170 subjects, and p-values were calculated by Cochran-Mantel-Haenszel chi-squared test on known data. Subsequently, we created a 3D GxE landscape plot of negative logarithm of the association of p-values for all the possible combinations of genetic and environmental factors with their hierarchical clustering. Thus, the GxE landscape plot is a valuable model to predict association of p-values for GxE and similarity among genotypes and environments in the context of disease pathogenesis.

Chemical exchange saturation transfer (CEST) imaging of amine protons exchanging at intermediate rates and whose chemical shift is around 2 ppm may provide a means of mapping creatine. However, the quantification of this effect may be compromised by the influence of overlapping CEST signals from fast-exchanging amines and hydroxyls. We aimed to investigate the exchange rate filtering effect of a variation of CEST, named chemical exchange rotation transfer (CERT), as a means of isolating creatine contributions at around 2 ppm from other overlapping signals. Simulations were performed to study the filtering effects of CERT for the selection of transfer effects from protons of specific exchange rates. Control samples containing the main metabolites in brain, bovine serum albumin (BSA) and egg white albumen (EWA) at their physiological concentrations and pH were used to study the ability of CERT to isolate molecules with amines at 2 ppm that exchange at intermediate rates, and corresponding methods were used for in vivo rat brain imaging. Simulations showed that exchange rate filtering can be combined with conventional filtering based on chemical shift. Studies on samples showed that signal contributions from creatine can be separated from those of other metabolites using this combined filter, but contributions from protein amines may still be significant. This exchange filtering can also be used for in vivo imaging. CERT provides more specific quantification of amines at 2 ppm that exchange at intermediate rates compared with conventional CEST imaging. Copyright © 2017 John Wiley & Sons, Ltd.

Arthroscopy has assumed an important place in wrist surgery. It requires specific operative skills that are now mainly acquired in the operating room. In other fields of endoscopic surgery, e-learning and virtual reality (VR) have introduced new perspectives in teaching skills. This leads to the following research question: Could the current way of teaching wrist arthroscopy skills be supported using new educational media, such as e-learning and simulator training? The literature was searched for available methods of teaching endoscopic skills. Articles were assessed on the evidence of validity. In addition, a survey was sent to all members of the European Wrist Arthroscopy Society (EWAS) to find out whether hand surgeons express a need to embrace modern educational tools such as e-learning or simulators for training of wrist arthroscopy skills. This study shows that the current way of teaching wrist arthroscopy skills can be supported using new educational media, such as e-learning and simulator training. Literature indicates that e-learning can be a valuable tool for teaching basic knowledge of arthroscopy and supports the hypothesis that the use of virtual reality and simulators in training enhances operative skills in surgical trainees. This survey indicates that 55 out of 65 respondents feel that an e-learning program would be a valuable asset and 62 out of the 65 respondents are positive on the additional value of wrist arthroscopy simulator in training. Study results support the need and relevance to strengthen current training of wrist arthroscopy using e-learning and simulator training. V.

Full Text Available Dilated cardiomyopathy (DCM is an important cause of heart failure with a strong familial component. We performed an exome-wide array-based association study (EWAS to assess the contribution of missense variants to sporadic DCM.116,855 single nucleotide variants (SNVs were analyzed in 2796 DCM patients and 6877 control subjects from 6 populations of European ancestry. We confirmed two previously identified associations with SNVs in BAG3 and ZBTB17 and discovered six novel DCM-associated loci (Q-value<0.01. The lead-SNVs at novel loci are common and located in TTN, SLC39A8, MLIP, FLNC, ALPK3 and FHOD3. In silico fine mapping identified HSPB7 as the most likely candidate at the ZBTB17 locus. Rare variant analysis (MAF<0.01 demonstrated significant association for TTN variants only (P = 0.0085. All candidate genes but one (SLC39A8 exhibit preferential expression in striated muscle tissues and mutations in TTN, BAG3, FLNC and FHOD3 are known to cause familial cardiomyopathy. We also investigated a panel of 48 known cardiomyopathy genes. Collectively, rare (n = 228, P = 0.0033 or common (n = 36, P = 0.019 variants with elevated in silico severity scores were associated with DCM, indicating that the spectrum of genes contributing to sporadic DCM extends beyond those identified here.We identified eight loci independently associated with sporadic DCM. The functions of the best candidate genes at these loci suggest that proteostasis regulation might play a role in DCM pathophysiology.

The authors are not interested in separate languages, but in a specified linguistic area as a whole. The contact of Polish, Lithuanian and Eastern-Slavonic dialects in North East Poland lasts several centuries and it is impossible to set the borders between these codes. Thus, the holistic approach is the best theoretical solution in question.   Recenzja Opracowanie Różnojęzyczne słownictwo gwarowe Podlasia, Suwalszczyzny i północno-wschodniego Mazowsza jest efektem nowatorskiego, kompleksowego podejścia badawczego w leksykografii.

Fertilized chicken eggs were divided into the following treatment groups: placebo, diamond NPs, graphite NPs, pristine graphene, small graphene oxide, large graphene oxide, and reduced graphene oxide. Experimental solutions at a concentration of 500 µg/mL were administrated into the egg albumin. Gross pathology and the rate of survival were examined after 5, 10, 15, and 20 days of incubation. After 20 days of incubation, blood samples were collected and the weight of the body and organs measured. The relative ratio of embryo survival decreased after treatment all treatments except diamond NPs. There was no correlation between the rate of survival and the ζ-potential or the surface charge of the CNPs in solution. Body and organ weight, red blood-cell morphology, blood serum biochemical parameters, and oxidative damage in the liver did not differ among the groups. These results indicate that CNPs can remain in blood circulation without any major side effects, suggesting their potential applicability as vehicles for drug delivery or active compounds per se. However, there is a need for further investigation of their properties, which vary depending on production methods and surface functionalization. Keywords: nanoparticles, diamond, graphite, graphene, toxicity, red blood cells, oxidative stress, surface charge

We conducted an epigenome-wide association study (EWAS) of DNA methylation in placenta in relation to maternal tobacco smoking during pregnancy and examined whether smoking-induced changes lead to low birthweight. DNA methylation in placenta was measured using the Illumina HumanMethylation450 BeadChip in 179 participants from the INfancia y Medio Ambiente (INMA) birth cohort. Methylation levels across 431 311 CpGs were tested for differential methylation between smokers and non-smokers in pregnancy. We took forward three top-ranking loci for further validation and replication by bisulfite pyrosequencing using data of 248 additional participants of the INMA cohort. We examined the association of methylation at smoking-associated loci with birthweight by applying a mediation analysis and a two-sample Mendelian randomization approach. Fifty CpGs were differentially methylated in placenta between smokers and non-smokers during pregnancy [false discovery rate (FDR) < 0.05]. We validated and replicated differential methylation at three top-ranking loci: cg27402634 located between LINC00086 and LEKR1, a gene previously related to birthweight in genome-wide association studies; cg20340720 (WBP1L); and cg25585967 and cg12294026 (TRIO). Dose-response relationships with maternal urine cotinine concentration during pregnancy were confirmed. Differential methylation at cg27402634 explained up to 36% of the lower birthweight in the offspring of smokers (Sobel P-value < 0.05). A two-sample Mendelian randomization analysis provided evidence that decreases in methylation levels at cg27402634 lead to decreases in birthweight. We identified novel loci differentially methylated in placenta in relation to maternal smoking during pregnancy. Adverse effects of maternal smoking on birthweight of the offspring may be mediated by alterations in the placental methylome. © The Author 2016; all rights reserved.

Full Text Available Neste texto, pretende-se apresentar, em resposta às condicionantes conceituais e metodológicas colocadas por Salerno, uma abordagem metodológica, a abordagem da atividade futura (AAF, que viabiliza a participação dos ergonomistas em projetos organizacionais. Nessa abordagem, que tem a Análise Ergonômica do Trabalho (AET como base, os ergonomistas não sustentam unicamente a posição clínica, característica da AET, mas assumem o papel de "atores do processo de projeto" a fim de cooperar com os diferentes atores da empresa: diretores, gerentes, engenheiros, trabalhadores. Todavia, a participação efetiva da Ergonomia depende de nova forma de conceber a organização, que deve ser abordada não somente através de sua dimensão estrutural, mas também através das "regulações sociais necessárias à manutenção e à construção da organização do trabalho".In response to Salerno's theoretical and methodological constraints to ergonomists participation in organisational design process, this paper proposes a new approach based in future work activity forecasting. Even if the Ergonomie Work Analysis (EWA is the underlying methodological tool, in this approach, ergonomists must assume a new role, as "actors of the design process", and co-operate with the others company actors: managers, engineers, foremen and workers. But to be more effective, ergonomie intervention needs a new framework of "organisation" issues. To be more effective, it will be argued that one must approach organisâtionnal design not only by its structural components but also by its inherent social interactions and adjustments.

The objective of the present ­investigation was to evaluate morphological characteristics of the assembles of gold and platinum nanoparticles (nano-Au and nano-Pt respectively, with Salmonella Enteritidis (Gram-negative and Listeria monocytogenes (Gram-positive, to reveal possibilities of constructing bacteria-nanoparticle vehicles.Methods: Hydrocolloids of nano-Au or nano-Pt were added to two bacteria suspensions in the following order: nano-Au + Salmonella Enteritidis; nano-Au + Listeria monocytogenes; nano-Pt + Salmonella Enteritidis; nano-Pt + Listeria monocytogenes. Samples were inspected by transmission electron microscope.Results: Visualization of morphological interaction between nano-Au and Salmonella Enteritidis and Listeria monocytogenes, showed that nano-Au were aggregated within flagella or biofilm network and did not penetrate the bacterial cell. The analysis of morphological effects of interaction of nano-Pt with bacteria revealed that nano-Pt entered cells of Listeria monocytogenes and were removed from the cells. In the case of Salmonella Enteritidis, nano-Pt were seen inside bacteria cells, probably bound to DNA and partly left bacterial cells. After washing and centrifugation, some of the nano-Pt-DNA complexes were observed within Salmonella Enteritidis.Conclusion: The results indicate that the bacteria could be used as a vehicle to deliver nano

Differences in DNA collection protocols may be a potential confounder in epigenome-wide association studies (EWAS) using a large number of blood specimens from multiple biobanks and/or cohorts. Here we show that pre-analytical procedures involved in DNA collection can induce systematic bias in the DNA methylation profiles of blood cells that can be adjusted by cell-type composition variables. In Experiment 1, whole blood from 16 volunteers was collected to examine the effect of a 24 h storage period at 4°C on DNA methylation profiles as measured using the Infinium HumanMethylation450 BeadChip array. Our statistical analysis showed that the P-value distribution of more than 450,000 CpG sites was similar to the theoretical distribution (in quantile-quantile plot, λ = 1.03) when comparing two control replicates, which was remarkably deviated from the theoretical distribution (λ = 1.50) when comparing control and storage conditions. We then considered cell-type composition as a possible cause of the observed bias in DNA methylation profiles and found that the bias associated with the cold storage condition was largely decreased (λ adjusted = 1.14) by taking into account a cell-type composition variable. As such, we compared four respective sample collection protocols used in large-scale Japanese biobanks or cohorts as well as two control replicates. Systematic biases in DNA methylation profiles were observed between control and three of four protocols without adjustment of cell-type composition (λ = 1.12-1.45) and no remarkable biases were seen after adjusting for cell-type composition in all four protocols (λ adjusted = 1.00-1.17). These results revealed important implications for comparing DNA methylation profiles between blood specimens from different sources and may lead to discovery of disease-associated DNA methylation markers and the development of DNA methylation profile-based predictive risk models.

Tsunami Information technology Modernization (TIM) is a National Oceanic and Atmospheric Administration (NOAA) project to update and standardize the earthquake and tsunami monitoring systems currently employed at the U.S. Tsunami Warning Centers in Ewa Beach, Hawaii (PTWC) and Palmer, Alaska (NTWC). While this project was funded by NOAA to solve a specific problem, the requirements that the delivered system be both open source and easily maintainable have resulted in the creation of a variety of open source (OS) software packages. The open source software is now complete and this is a presentation of the OS Software that has been funded by NOAA for benefit of the entire seismic community. The design architecture comprises three distinct components: (1) The user interface, (2) The real-time data acquisition and processing system and (3) The scientific algorithm library. The system follows a modular design with loose coupling between components. We now identify the major project constituents. The user interface, CAVE, is written in Java and is compatible with the existing National Weather Service (NWS) open source graphical system AWIPS. The selected real-time seismic acquisition and processing system is open source SeisComp3 (sc3). The seismic library (libseismic) contains numerous custom written and wrapped open source seismic algorithms (e.g., ML/mb/Ms/Mwp, mantle magnitude (Mm), w-phase moment tensor, bodywave moment tensor, finite-fault inversion, array processing). The seismic library is organized in a way (function naming and usage) that will be familiar to users of Matlab. The seismic library extends sc3 so that it can be called by the real-time system, but it can also be driven and tested outside of sc3, for example, by ObsPy or Earthworm. To unify the three principal components we have developed a flexible and lightweight communication layer called SeismoEdex.

The objective of this study was to evaluate the toxicity of nanoparticles comprised of pristine graphene, reduced graphene oxide, graphene oxide, graphite, and ultradispersed detonation diamond in a U87 cell line. The scope of the work consisted of structural analysis of the nanoparticles using transmission electron microscopy, evaluation of cell morphology, and assessment of cell viability by Trypan blue assay and level of DNA fragmentation of U87 cells after 24 hours of incubation with 50 µg/mL carbon nanoparticles. DNA fragmentation was studied using single-cell gel electrophoresis. Incubation with nanoparticles containing the allotropes of carbon did not alter the morphology of the U87 cancer cells. However, incubation with pristine graphene and reduced graphene oxide led to a significant decrease in cell viability, whereas incubation with graphene oxide, graphite, and ultradispersed detonation diamond led to a smaller decrease in cell viability. The results of a comet assay demonstrated that pristine graphene, reduced graphene oxide, graphite, and ultradispersed detonation diamond caused DNA damage and were therefore genotoxic in U87 cells, whereas graphene oxide was not.Keywords: nanostructures, graphene, graphite, diamond, glioblastoma multiforme, geno toxicity

In 2010, the U.S. National Weather Service (NWS) funded a three year project to integrate social science into their Tsunami Program. One of three primary requirements of the grant was to make improvements to tsunami warning messages of the NWS' two Tsunami Warning Centers- the West Coast/Alaska Tsunami Warning Center (WCATWC) in Palmer, Alaska and the Pacific Tsunami Warning Center (PTWC) in Ewa Beach, Hawaii. We conducted focus group meetings with a purposive sample of local, state and Federal stakeholders and emergency managers in six states (AK, WA, OR, CA, HI and NC) and two US Territories (US Virgin Islands and American Samoa) to qualitatively asses information needs in tsunami warning messages using WCATWC tsunami messages for the March 2011 Tohoku earthquake and tsunami event. We also reviewed research literature on behavioral response to warnings to develop a tsunami warning message metric that could be used to guide revisions to tsunami warning messages of both warning centers. The message metric is divided into categories of Message Content, Style, Order and Formatting and Receiver Characteristics. A message is evaluated by cross-referencing the message with the operational definitions of metric factors. Findings are then used to guide revisions of the message until the characteristics of each factor are met. Using findings from this project and findings from a parallel NWS Warning Tiger Team study led by T. Nicolini, the WCATWC implemented the first of two phases of revisions to their warning messages in November 2012. A second phase of additional changes, which will fully implement the redesign of messages based on the metric, is in progress. The resulting messages will reflect current state-of-the-art knowledge on warning message effectiveness. Here we present the message metric; evidence-based rational for message factors; and examples of previous, existing and proposed messages.

This conference, organized by the Mineral Sciences and Engineering Section of the Metallurgical Society of CIM acknowledged that strong economic growth is the driving force behind record high productivity in the mining industry. The industry must strive to meet the higher demand for raw materials while facing the challenge of stringent environmental constraints. The continuing success of the mining industry will depend on efficient and environmentally sound mineral processing, particularly since the industry has been forced to exploit more complex forms of minerals given the gradual depletion of high-grade mineral resources. In addition to shortages in qualified personnel in mineral processing, the industry is currently facing a general reduction in basic research and training programs, resulting in deficiencies in technologies needed to process complex ores. World experts in mineral processing participated at this conference to share their novel research in fine particle processing, applications of atomic force microscopy, flotation research, particle interactions in mineral processing, flotation froths, grinding, rheology and sulphide flotation chemistry. The sessions of the conference were entitled: atomic force microscopy in flotation research particulate interactions; flotation froths, flocculation and dewatering; grinding and rheology surfactants; flotation froths, particle-bubble interactions; sulphide flotation; and, general flotation froths. The conference featured 37 presentations, of which 6 have been catalogued separately for inclusion in this database. refs., tabs., figs.

The article is an attempt of a new outlook first of all upon scientific output of many years' (the years 1878 - 1909) lecturer on Russian State Law in the Imperial University of Warsaw--Aleksandr Lwowicz Błok. Historians of literature, researchers of life and output of the scientist's son, an eminent poet-symbolist Aleksandr A. Błok, to a high degree were able to reconstruct lot of life and vicissitudes of the Warsaw professor. Thanks to the preserved university archival materials it was possible to add many details to Błok's biography, especially concerning his professional problems. They were connected with dramatic events in personal life of the professor. According to relations of the part of his university co-workers and students, the circumstances even brought about the symptoms of the mental illness. Prematurely elderly he was a man deeply miserable, lonely and deprived of understanding by associates. Up till now his scientific output has not been described precisely enough. Not numerous memories of his contemporaries (Szymon Askenazy, Nikołaj Dubrowskij) and even inconspicuous modern researches of the Polish (Janusz Woliński) brought about, in the author's opinion, too simplified and schematic character-sketch of Błok as a Russificator and nationalist, mediocre scholar and much worse lecturer. A scientific output of Błok is, indeed, inostensible--he published 2 books only--Master's thesis entitled: Władza państwowa w społeczeństwie europejskim. Poglad na polityczna teorie Lorenza Steina i na francuska rzeczywistość polityczna (1880) [State Authority in European Society. Outlook upon Political Theory of Lorenz Stein and French Political Facts (1880)] and Literatura polityczna w Rosj i o Rosji (1884) [Political Literature in Russia and on Russia (1884)] as an introduction to his course in State Law. Two thirds, so over 20 years of work, he gave to the not accomplished conception of creating a new classification of sciences that together with its

The role of endorphins and the association of cognitive dysfunction and negative symptoms are postulated.Methods: In this study, 43 patients with schizophrenia, five first-degree relatives, and 34 healthy controls were examined. Participants’ plasma concentrations of substance P, β-endorphin, and calcitonin gene-related peptide (CGRP were assessed. In patients, the Trail-Making Test, the Color Reading Interference Test (Stroop test, and the Positive and Negative Syndrome Scale Negative Syndrome subscale (PANSS N test were performed. We also evaluated pain threshold using nociceptive reflex (RTIII testing.Results: The mean β-endorphin concentration was about 20% higher in patients than in healthy controls (P<0.05. CGRP concentrations were significantly higher in patients than in controls (5.34 ng/mL versus 4.16 ng/mL; P<0.01. Subjects treated with antipsychotic polytherapy had higher concentrations of CGRP than did patients treated with second-generation antipsychotic monotherapy (5.92 ng/mL versus 5.02 ng/mL; P<0.05. There were no correlations between any biochemical parameters and Trail-Making Test, Stroop test, and PANSS N scores. There were no differences in RTIII among study groups. Strong negative correlation (P<0.001 was found between PANSS N scores and subjective pain threshold on the right lower limb.Conclusion: The insensitivity to pain in schizophrenia is a complex phenomenon that is probably not related to changes in nociceptive pathways.

The paper summarises the moral and spiritual factors important in care for sick people. Medical care is one of the ancient forms of our activity as humans, expounding care for other people's well-being. The moral aspect of medical care is deeply rooted in constant daily interaction between the patient and the doctor aiming at easing symptoms, support, help, prevention and defense. Such teleological orientation of medicine is, according to John Paul II, made possible not so much by technology but by physician's conscience, wisdom and unlimited honesty. This is where ethics is needed to regulate that particular relation. This ethics stems from Christian morality, which raises our role as humans to that of guardians of dignity of another human being. Man is indeed the measure of all things, and this becomes the context for all relations including man's relation to God, but also relation of God to man. Thus, human dignity assumes the status of unconditional natural rule, inherently forestalling all legal arrangements. The morality of health care requires holistic approach, including care for body, mind, social interaction and spiritual needs. Only then, as explained by dr Ewa Kucharska, is it possible to answer patient's all needs. The moral side of the therapeutic contract bounds the doctor and the patient, alike. From this point of view, it is immoral not to cooperate with physicians in their strife for the preservation of health and life itself. Self negligence or active self harm (drugs, alcohol abuse, HIV/AIDS) are the utmost examples of such dishonesty. Finally, the imperative to bring hope and faith to the suffering, vests special importance in hospital chaplains, who bring good word, but most importantly the sacrament to those in need. The prayer in turn may evoke strong hope for cure, capable of supporting both soul and body. The suffering of man cannot be understood on rational grounds. It requires acceptance, and, above all, it requires faith. And this

This study aims to analyze plasma levels of MMP-2 and TIMP-2 in plaque psoriasis patients before and after the course of narrowband ultraviolet-B (NBUVB therapy with respect to disease advancement. Patients and methods: A total of 49 patients suffering from plaque psoriasis and 40 healthy volunteers were enrolled into the study. Plasma levels of MMP-2 and TIMP-2 were determined using enzyme-linked immunosorbent assay, while Psoriasis Area and Severity Index (PASI was used to define the disease advancement. Results: The results showed increased plasma levels of MMP-2 and TIMP-2, but this change was significant only in case of MMP-2 in total psoriatic group compared to healthy subjects. Moreover, there was an increase in the concentrations of chosen factors with an increase in the severity of the disease. The NBUVB therapy causes a decline in the concentration of the analyzed enzyme and its inhibitor, although this change was statistically significant in the total psoriatic group only in case of MMP-2. There was also a positive correlation between MMP-2, TIMP-2, and PASI score value. Conclusion: Our study highlights a possible important role of MMP-2 in the activity of psoriasis and clearance of disease symptoms. Moreover, plasma MMP-2 seems to be a valuable psoriasis biomarker.

However, information about their toxicity and biocompatibility is limited. The objective of this study is to evaluate the toxicity of graphene oxide (GO and reduced graphene oxide (rGO platelets, using U87 and U118 glioma cell lines for an in vitro model and U87 tumors cultured on chicken embryo chorioallantoic membrane for an in vivo model. The in vitro investigation consisted of structural analysis of GO and rGO platelets using transmission elec­tron microscopy, evaluation of cell morphology and ultrastructure, assessment of cell viability by XTT assay, and investigation of cell proliferation by BrdU assay. Toxicity in U87 glioma tumors was evaluated by calculation of weight and volume of tumors and analyses of ultrastructure, histology, and protein expression. The in vitro results indicate that GO and rGO enter glioma cells and have different cytotoxicity. Both types of platelets reduced cell viability and proliferation with increasing doses, but rGO was more toxic than GO. The mass and volume of tumors were reduced in vivo after injection of GO and rGO. Moreover, the level of apoptotic markers increased in rGO-treated tumors. We show that rGO induces cell death mostly through apoptosis, indicating the potential applicability of

Although benign in the majority of patients, the natural course of the disease may result in significant disturbance of body morphology, reduced thoracic volume, impaired respiration, increased rates of back pain, and serious esthetic concerns. Risk of deterioration is highest during the pubertal growth spurt and increases the risk of pathologic spinal curvature, increasing angular value, trunk imbalance, and thoracic deformity. Early clinical detection of scoliosis relies on careful examination of trunk shape and is subject to screening programs in some regions. Treatment options are physiotherapy, corrective bracing, or surgery for mild, moderate, or severe scoliosis, respectively, with both the actual degree of deformity and prognosis being taken into account. Physiotherapy used in mild idiopathic scoliosis comprises general training of the trunk musculature and physical capacity, while specific physiotherapeutic techniques aim to address the spinal curvature itself, attempting to achieve self-correction with active trunk movements developed in a three-dimensional space by an instructed adolescent under visual and proprioceptive control. Moderate but progressive idiopathic scoliosis in skeletally immature adolescents can be successfully halted using a corrective brace which has to be worn full time for several months or until skeletal maturity, and is able to prevent more severe deformity and avoid

At the same time, body iron accumulation is associated with high risk of different morbidities.Purpose: We hypothesized that Nordic Walking training would result in pro-healthy changes in an elderly group of subjects by reducing body iron stores via shifts in iron metabolism-regulating proteins.Methods: Thirty-seven women aged 67.7±5.3 years participated in this study. They underwent 32 weeks of training, 1-hour sessions three times a week, between October 2012 and May 2013. Fitness level, blood morphology, CRP, vitamin D, ferritin, hepcidin, and soluble Hjv were assessed before and after the training.Results: The training program caused a significant decrease in ferritin, which serves as a good marker of body iron stores. Simultaneously, the physical cardiorespiratory fitness had improved. Furthermore, blood hepcidin was positively correlated with the ferritin concentration after the training. The concentration of blood CRP dropped, but the change was nonsignificant. The applied training

The objective of the present study was to determine the effect of administration of nano-Au, HS, and a nano-Au+HS complex on the morphological and molecular characteristics of breast muscle during embryogenesis.Methods: Chicken embryos were used as in vivo model. Fertilized chicken eggs (n = 350 were randomly divided into the control group and the groups treated with nano-Au, HS, and nano-Au+HS. The experimental solutions were given in ovo on the first day of incubation and the embryos were evaluated on day 20 of incubation. The methods included biochemical indi- ces in blood, immunohistochemistry, microscopy (transmission electron microscopy, scanning electron microscopy, confocal, and gene expression at the messenger ribonucleic acid and protein levels.Results: The treatments did not adversely affect mortality, organ weight, and homeostasis of the embryos. HS stimulated the development and maturation of breast muscle by increasing the number of nuclei, satellite cells, and muscle fibers and affected the expression of basic fibroblast growth factor-2 and paired-box transcription factor-7.

Epigenetic regulation in anxiety is suggested, but evidence from large studies is needed. We conducted an epigenome-wide association study (EWAS) on anxiety in a population-based cohort and validated our finding in a clinical cohort as well as a murine model. In the KORA cohort, participants (n=1522, age 32-72 years) were administered the Generalized Anxiety Disorder (GAD-7) instrument, whole blood DNA methylation was measured (Illumina 450K BeadChip), and circulating levels of hs-CRP and IL-18 were assessed in the association between anxiety and methylation. DNA methylation was measured using the same instrument in a study of patients with anxiety disorders recruited at the Max Planck Institute of Psychiatry (MPIP, 131 non-medicated cases and 169 controls). To expand our mechanistic understanding, these findings were reverse translated in a mouse model of acute social defeat stress. In the KORA study, participants were classified according to mild, moderate, or severe levels of anxiety (29.4%/6.0%/1.5%, respectively). Severe anxiety was associated with 48.5% increased methylation at a single CpG site (cg12701571) located in the promoter of the gene encoding Asb1 (β-coefficient=0.56 standard error (SE)=0.10, p (Bonferroni)=0.005), a protein hypothetically involved in regulation of cytokine signaling. An interaction between IL-18 and severe anxiety with methylation of this CpG cite showed a tendency towards significance in the total population (p=0.083) and a significant interaction among women (p=0.014). Methylation of the same CpG was positively associated with Panic and Agoraphobia scale (PAS) scores (β=0.005, SE=0.002, p=0.021, n=131) among cases in the MPIP study. In a murine model of acute social defeat stress, Asb1 gene expression was significantly upregulated in a tissue-specific manner (p=0.006), which correlated with upregulation of the neuroimmunomodulating cytokine interleukin 1 beta. Our findings suggest epigenetic regulation of the stress

The research reactor MARIA has been in operation for more than twenty years and all the spent fuel assemblies used since the first commissioning of the reactor are stored in wet facility on site. The present paper deals with the spent fuel MR-6 encapsulation technology in MARIA reactor. The encapsulated spent MR-6 fuel will be stored under water in the same pool unless some other solution is available. The capsules made of stainless steel are capable to accommodate one MR-6 fuel assembly. The encapsulation process is performed in the hot cell by the MARIA reactor. The spent fuel having its leg cut off is loaded to the transport cylinder manually and next transferred to a trolley. The trolley is moving to a position directly below the entrance to the hot cell and the spent fuel is entering the hot cell. The spent fuel assembly is then put into the drying cell. Dried out spent fuel is moved into the capsule mounted on the grip of the machine. Next, the capsule lid is pressed in and welded. After the leak test and filling up with helium the capsule returns from the hot cell to the pool. The hermetic capsule is sunk back into the water and positioned in the separator . The results presented earlier show, that the limiting time of WWR-SM and Ek-10 type spent fuel residence in wet storage is about 40-45 years. Therefore, the systematic quality investigation of all Ek-10 fuel elements and WWR-SM fuel assemblies discharged from EWA reactor in the period of 1959-1969 was performed. Altogether, about 2500 Ek-10 fuel elements and 47 WWR-SM fuel assemblies were investigated. The results of these investigations are presented in the present work. The sipping test, visual investigation and ultrasonic techniques were used for that purpose. The radioactive isotope Cs-137 was used as the indicator of fission product release from the fuel assembly. Taking into account the value of Cs-137 release from damaged WWR-SM fuel assembly the criteria of damaged fuel assembly were proposed. It

Full Text Available The current issue of Studies in Second Language Learning and Teaching brings together six contributions written by scholars from Poland and abroad which deal with a wide array of issues related to learning and teaching additional languages in different educational contexts. First, Weronika Szubko-Sitarek reports the findings of two experimental studies conducted within the lexical decision task paradigm which aimed to investigate the cognate facilitation effect in the process of recognizing words in a third language by Polish unbalanced trilinguals who, in addition to their mother tongue, were proficient in English and had variable command of German. In the next paper, Sane M. Yagi and Saleh Al-Salman make a strong case for the use of tracking software in writing pedagogy as a tool for providing invaluable insights into the process of composing texts, but also a method of stimulating reflection and promoting strategic learning. The research-based contributions by Ewa Waniek-Klimczak and Aleksandra Wach, in turn, shift the emphasis to sociolinguistic issues. The former presents the findings of a qualitative study which examined the acculturation patterns of three recent Polish immigrants to the United Kingdom, who were expert users of English, in relation to their formal and informal language learning experiences, while the latter uses questionnaire data obtained from a respectable sample of Polish-speaking English majors to shed light on their preferences concerning pronunciation norms based on the native-speaker model and the Lingua Franca Core. The last two papers included in this issue report the findings of studies exploring the role of anxiety in learning foreign language skills and subsystems. In the first of these, Christina Gkonou examines the interfaces between speaking and writing anxiety manifested by Greek learners of English as a foreign language in a private school setting and, in the second, Magdalena Szyszka taps the relationship

Background: Prenatal exposure to maternal cigarette smoking (prenatal smoke exposure) had been associated with altered DNA methylation (DNAm) at birth. Objective: We examined whether such alterations are present from birth through adolescence. Methods: We used the Infinium HumanMethylation450K BeadChip to search across 473,395 CpGs for differential DNAm associated with prenatal smoke exposure during adolescence in a discovery cohort (n = 132) and at birth, during childhood, and during adolescence in a replication cohort (n = 447). Results: In the discovery cohort, we found five CpGs in MYO1G (top-ranking CpG: cg12803068, p = 3.3 × 10–11) and CNTNAP2 (cg25949550, p = 4.0 × 10–9) to be differentially methylated between exposed and nonexposed individuals during adolescence. The CpGs in MYO1G and CNTNAP2 were associated, respectively, with higher and lower DNAm in exposed versus nonexposed adolescents. The same CpGs were differentially methylated at birth, during childhood, and during adolescence in the replication cohort. In both cohorts and at all developmental time points, the differential DNAm was in the same direction and of a similar magnitude, and was not altered appreciably by adjustment for current smoking by the participants or their parents. In addition, four of the five EWAS (epigenome-wide association study)–significant CpGs in the adolescent discovery cohort were also among the top sites of differential methylation in a previous birth cohort, and differential methylation of CpGs in CYP1A1, AHRR, and GFI1 observed in that study was also evident in our discovery cohort. Conclusions: Our findings suggest that modifications of DNAm associated with prenatal maternal smoking may persist in exposed offspring for many years—at least until adolescence.

This register study explored the prevalence of diagnosed ADHD and incidence of newly diagnosed ADHD in Swedish adults over time, and assessed comorbidities and pharmacologic treatment. Methods: National Patient Register data were used to estimate the overall prevalence of adults (≥18 years with a registered ADHD diagnosis from 2006 to 2011, and the incidence of newly registered diagnoses from 2007 to 2011. Data from the Prescribed Drug Register were used to estimate the mean dose of the most frequently prescribed ADHD medication. Results: The estimated annual prevalence (N=44,364 of diagnosed ADHD increased from 0.58 per 1,000 persons in 2006 to 3.54 per 1,000 persons in 2011.

Materials and methods: A total of 110 three-unit Y-TZP FDP cores with one intermediate pontic were made. The FDP cores in groups 1–7 were made with a split-file design, veneered with manually built-up porcelain, computer-aided design-on veneers, and over-pressed veneers. Groups 8–11 consisted of FDPs with a state-of-the-art design, veneered with manually built-up porcelain. All the FDP cores were subjected to simulated aging and finally loaded to fracture. Results: There was a significant difference (P<0.05 between the core designs, but not between the different types of Y-TZP materials. The split-file designs with VITABLOCS® (1,806±165 N and e.max® ZirPress (1,854±115 N and the state-of-the-art design with VITA VM® 9 (1,849±150 N demonstrated the highest mean fracture values. Conclusion: The shape of a split-file designed all-ceramic reconstruction calls for a different dimension protocol, compared to traditionally shaped ones, as the split-file design leads to sharp approximal indentations acting as fractural impressions, thus decreasing the overall strength. The design of a framework is a crucial factor for the load bearing capacity of an all-ceramic FDP. The state-of-the-art design is preferable since the split-file designed cores call for a cross-sectional connector area at least 42% larger, to have the same load bearing capacity as the state-of-the-art designed

Occurring in five of 1000 live-born infants globally and even more in developing countries, HIE is a serious problem that causes death in 25%–50% of affected neonates and neurological disability to at least 25% of survivors. In order to prevent the damage caused by HIE, our invention provides an effective whole-body cooling of the neonates by utilizing evaporation and an endothermic reaction. Our device is composed of basic electronics, clay pots, sand, and urea-based instant cold pack powder. A larger clay pot, lined with nearly 5 cm of sand, contains a smaller pot, where the neonate will be placed for therapeutic treatment. When the sand is mixed with instant cold pack urea powder and wetted with water, the device can extract heat from inside to outside and maintain the inner pot at 17°C for more than 24 hours with monitoring by LED lights and thermistors

Full text: International safety experts last week concluded a two-week International Atomic Energy Agency (IAEA) mission to review the regulatory framework for nuclear and radiation safety in Poland. In its preliminary report, the Integrated Regulatory Review Service (IRRS) mission team found that Poland's nuclear regulator, Panstwowa Agencja Atomistyki (PAA), has a clear commitment to safety, a high level of transparency, competent staff and leadership, and a good recognition of challenges ahead related to Poland's efforts to develop nuclear power. ''Poland's regulatory framework and the work of PAA give high confidence of strong radiation protection for the Polish people. Further, there has been significant progress in the development of Poland's regulatory framework in preparation for the challenge of regulating nuclear power,'' said team leader Robert Lewis, a senior executive in the US Nuclear Regulatory Commission. The mission was conducted at the request of the Government of Poland from 15-25 April. The team was made up of 11 regulatory experts from Belgium, the Czech Republic, Finland, France, the Republic of Korea, Slovakia, Slovenia, Sweden, the United Arab Emirates, the United Kingdom and the United States, as well as five IAEA staff members. The IRRS review team was very thorough in its review, and we welcome its advice on how to continue to improve our programmes to protect people and the environment , said Janusz Wlodarski, President of PAA. The team interviewed members of PAA and officials from various ministries, as well as key players in the Polish safety framework. Such IRRS missions are peer reviews based on IAEA Safety Standards, not inspections or audits. Among its main observations the IRRS review team identified the following good practices: Applying the considerable experience of PAA's senior management to regulatory issues; The introduction of changes to Poland's laws and regulations following broad public consultation at an early stage in

Full Text Available In Between. Two Home Countries in the Polish Language Press for Jewish Children in the Second Polish Republic In the interwar period in Poland the big Polish-language Jewish journals (Chwila, Nowy Dziennik and Nasz Przegląd published supplements for children. Two of them (Chwilka and Dzienniczek dla Dzieci i Młodzieży [Diary for children and young people] were typical magazines for children. The third, the Mały Przegląd [Little review], led initially by Janusz Korczak, became the tribune of its youngest readers. Its content was composed of letters, reports and interviews by young correspondents. All these magazines were directed to children of the accultured Jews, readers of Polish-language Zionist press. It would seem, therefore, that their educational ideals should be similar. How were the patriotic values shown to the Jewish children from the acculturated Zionist families, familiar with Polish culture better than average Jewish children, but raised in cult of Palestine and the return to Eretz? What should be told to the children, if they were to be educated as good patriots? And patriots of what country? How to explain Palestinian patriotism to children who have never seen their country, lived in Poland and spoke Polish? And at the same time – how to explain the Polish patriotism to children who live in a country with a constantly growing anti-Semitism, of which they are only the marginalized, second-class citizens. As a result, the two dailies, almost identical in their views, have supplements presenting a surprisingly different approach to patriotism.

photosynthetic systems. The next paper, by Olejnik et al, discussed metallic QDs which enhance photosynthetic function in light-harvesting biomolecular complexes. Such hybrid structures with gold QDs are shown to exhibit a strong increase in the fluorescence quantum yield. The next two papers, by Sikora et al and Kaminska et al deal with the ZnO nanoparticles passivated by MgO. In the first of these two papers, the authors describe the behavior of ZnO/MgO when introduced to human cancer cells. In the second, the authors describe the QDs with an extra outer layer of Fe2O3 which makes the nanoparticles superparamagnetic and also capable of generation of reactive oxygen species which could be applied to form localized centers of toxicity for cancer treatment. Finally, in the last paper by Yatsunenko et al, the authors discuss several semiconducting QDs like ZnO with various rare-earth dopands. They propose a microwave-driven hydrothermal technology to make them, characterize their luminescence and demonstrate their usefulness in the early recognition of cancer tissues.

In many of her literary works, the writer and columnist Eliza Orzeszkowa (1841-1910), who was twice nominated for the Nobel Prize in literature (1905, 1909), depicted the life of the Polish society in the eastern lands of the former Polish-Lithuanian Commonwealth in the second half of the 19th century. A great lover of nature, Orzeszkowa appreciated the botanical knowledge of the local rural population in the vicinities of Grodno. She combined attempts to master that knowledge with her other great passion, that of investigating folk culture, and was always ready to listen to what women who were village herbalists had to tell her about medicinal plants, and about the customs and legends connected with the medical practices based on herbal remedies. She then passed on the information to botanists for scientific verification. Orzeszkowa's naturalist and ethnographic fascinations led her to write a cycle of articles on "The people and flowers on the Niemen river", published in 1888-1891 in the ethnographic-tourist magazine "Wisła". This collection of articles has been analysed not only by historians of literature, but also, since 1985, by historians of science. The first analysis was conducted at the Section for the History of Pharmacy of the Institute of the History of Science of the Polish Academy of Sciences. This yielded Ewa Kamińska's study: Ziołoznawstwo i ziołolecznictwo w publikacjach etnograficznych Elizy Orzeszkowej [The knowledge of herbs and medicine based on herbal remedies in the ethnographic publications of Eliza Orzeszkowa] published as part of the Institute's Historia leków naturalnych [History of natural medicines], ed.

Full text: The first hydrogel for wound dressing processed by radiation left the laboratories in Poland in 1986 by the hands of its inventor Janusz M. Rosiak and soon, after formal tests, arrived in the local market (1992). It was a technological breakthrough due to its product characteristics as pain reliever and enhanced healing properties besides its clever production process combining sterilization and crosslinking in a simultaneous operation (Rosiak a, 1989; Rosiak b, 1995). IAEA invited professor Rosiak to supported the transference of his technology for many laboratories around the world. The laboratories of developing countries, which face all kinds of restrictions, were seduced by the simplicity of the process and low cost of its raw materials. This was the seed of the flourishing activities in hydrogel dressings in Brazil and other developing countries. The so-called 'Rosiak membrane' have been applied in many european countries for the healing of burn wounds, ulcers, cosmetology purposes and so on. In the opinion of some physicians, the main therapeutic features of them are their ability to stop the pain and their capacity of absorption of exudates, besides many other properties as transparency, permeation of oxygen, cooling effect of water evaporation and so on. The pain relief property is controlled by a delicate balance of softness and proper consistency to be used as dressings as previously showed (Lugao a, 2000, Miranda a, 2000).The network features command the amount of exudates absorbed by the dressing and the permeability of drugs by the net. Although, its excellent healing properties confirmed by clinical use, its handling properties are still difficult (Lugao b, 1998, Miranda b, 1999). The methodology of membrane preparation is as follow: all polymers were medical grade: poli(N-vinil2- pirrolidona)/PVP-K90, from PLASDONE; agar/Agar Technical No 3, from OXOID; poly(ethylene-glycoD/ATPEG-300, from OXITENO.

In the framework of the ENSEMBLE project dealing with further development of long distance atmospheric dispersion prognosis suitable for decision making process a new computing cluster of Beowulf type was built on Intel platform. The cluster consists of four two-processors machines connected with Gigabit Ethernet and is equipped with software allowing for development of parallel and distributed computing based on MPI and PVM standard libraries. Group of Measuring Methods for Atmospheric Pollution is concerned with methods of measuring the concentration of volatile pollutants and dust particles in the flue gas emitted by power plants and with physico-chemical methods of removal of volatile organic compounds from the flue gas. It is also developing the monitoring system for the industrial installation removing SO 2 and NO x from the flue gas at EPS Pomorzany. In 2001 the study of the distribution of polycyclic aromatic hydrocarbons between fly ash and the corresponding gas phase in the flue gas (some carcinogenic) emitted from coal-fired boiler at EPS Kaweczyn were carried out. In the pilot plant at Kaweczyn the investigations of PAHs removal efficiency versus dose were undertaken in co-operation with the Institute of Nuclear Chemistry and Technology in Warsaw and the Institute for Chemical Processing of Coal in Gliwice. In 2001 were started the optimization tests of the industrial demonstration plant for removal of SO 2 and NO x from flue gas using electron beam from accelerators in EPS Pomorzany in Szczecin. The reference measurement were carried out to test the monitoring system for determination of flue gas composition as well the flow rate and humidity measurement. Dr Janusz Licki has been invited to Malaysia as the IAEA Vienna expert to supervise the commissioning of the pilot plant for electron dry scrubbing process in MINT for two stays, two week each. Group of Numerical Linear Algebra is concerned with numerical methods for solving large linear systems

Full text: In 2010 our institute was again ranked among the best (class A) research organizations. This was mainly thanks to a large number of publications in prestigious scientific journals. A good example is given by prof. Janusz Wilczynski, who was awarded the prize for the best achievement in IPJ in 2010 in basic research. He published a series of papers in '' Physical Review Letters '' and '' Physical Review '' devoted to the discovery and study of a new mechanism of fast ternary or quaternary breakup of a heavy system into massive fragments. Experimental results obtained at LNS Catania in collaboration with an international, mostly Italian and Polish, were analyzed and interpreted by prof. Wilczynski and his collaborators. The corresponding award for applied research was given to dr Lukasz Swiderski for studies of liquid scintillators, in particular loaded with boron-10, as neutron detectors (work done in collaboration between IPJ and Germany). This work was a response to the world crisis of the shortage of 3 He, needed for neutron detection. Such detectors are used e.g. for security control at all borders and airports. The results of dr Swiderski show a path for application of liquid scintillators as neutron detectors for border monitoring. The synergy between basic and applied research was always the strong point of IPJ. The most evident case of this synergy is the construction of sophisticated apparatus for large international experiments. The largest one - the LHC at CERN in Geneva - began to collect data with the world record collision energy of 7 TeV. They are being analyzed with the participation of our physicists. In order to reach the designed beam energy and intensity, one needs to modernize several elements of the accelerator chain. In 2010 IPJ delivered for CERN a proton buncher and started preparation for production of Pi-mode Structures for the Linac4 accelerator. The second largest European research project is the X-ray Free-Electron Laser (E

The Institute of Atomic Energy (IAE) emerged in 1983 as one of three research institutes formed on the basis of the Institute of Nuclear Research. Originally the main task for the IAE was research in the field of the reactor physics and techniques needed for nuclear power plant operation and maintenance. Since nineties the priorities were broadened. At present they cover the basic and applied research aiming at the development of both pro ecological energy systems and applications of new nuclear technologies in medicine and industry including nuclear and non-nuclear energy sources.The main research facility of the IAE is the MARIA reactor of 30 MW (thermal). In 2001 the reactor was used mainly for production of radioisotopes for medicine and for neutron scattering studies. The decommissioning of the old reactor EWA was finished and the final reports were prepared. In 2001 the reactor MARIA completed 36 operational cycles with operation time of 3598 hours. No abnormal situations occurred. In the frame of implementation of medium enriched fuel in MARIA reactor, at the end of 2001 only two 80% enriched fuel assembly were used in reactor core. The full conversion was expected at the beginning of 2002. The analysis of the physical parameters for operating purposes of the reactor and the exploitation of spent fuel storage facilities were performed. Based on the results from the WIW-300 installation, the flow resistance in primary fuel cooling circuit in the case of boiling was evaluated. To prevent the corrosion damage of MR spent fuel stored in technological pool of MARIA reactor, the encapsulation technology was adapted. The ecology, economy and safety of nuclear facilities were considered, taking into account the possibility of construction of a nuclear power plant in Poland. The experiments of interaction of fast neutrons from spallation source with U/Pb pile in JINR (Dubna) were performed. The Institute has also started the design and construction of a facility for

In section three, dedicated to the teaching of publishing at the university level, Aušra Navickienė (Third Level Publishing Studies: Lithuania, a Case Study, Ewa Jabłońska-Stefanowicz (Three R’s in publishing education, and Josipa Selthofer (What comes first? Publishing business or publishing studies? provide examples of publishing studies programmes in Lithuania (focusing on the Institute of Book Science and Documentation of Vilnius University, Poland (focusing on the LIS Institute of the University of Wroclaw and Croatia, in comparison with relevant programmes in Europe and the United States. Finally, section four presents three papers which petition for the status of publishing studies as an emerging scientific discipline. Sophie Noël in Publishing studies: the search for an elusive academic object questions the validity of publishing studies as an academic discipline, while trying to situate them within the field of social sciences. She argues that a more appropriate frame could be adopted to describe what people studying the transformations of book publishing do – or should do – both at a theoretical and methodological levels. Christoph Bläsi (Publishing studies: being part of a cultural practice plus x? relates the question of an advanced self-conception of publishing studies to the question what criteria have to be fulfilled to call a field (such as publishing studies a scholarly discipline. He presents the first results of an ongoing project in which he conducts extensive expert interviews with representatives of UK Publishing Studies study programmes and
