Midwifery has developed its own philosophy to formalise its unique identity as a profession. Newly-graduated midwives are taught, and ideally embrace, this philosophy during their education. However, embarking in their career within a predominantly institutionalised and the medically focused health-care model may challenge this application. The research question guiding this study was as follows: 'How do newly graduated midwives deal with applying the philosophy of midwifery in their first six months of practice?' The aim was to generate a grounded theory around this social process. This Western Australian grounded theory study is conceptualised within the social theory of symbolic interactionism. Data were collected by means of in-depth, semi-structured interviews with 11 recent midwifery graduates. Participant and interviewer's journals provided supplementary data. The 'constant comparison' approach was used for data analysis. The substantive theory of transcending barriers was generated. Three stages in transcending barriers were identified: Addressing personal attributes, Understanding the 'bigger picture', and finally, 'Evaluating, planning and acting' to provide woman-centred care. An overview of these three stages provides the focus of this article. The theory of transcending barriers provides a new perspective on how newly-graduated midwives deal with applying the philosophy of midwifery in their first six months of practice. A number of implications for pre and post registration midwifery education and policy development are suggested, as well as recommendations for future research. Copyright © 2013 Elsevier Ltd.

To advance evidence on newly graduated nurses' use of knowledge sources. Clinical decisions need to be evidence-based and understanding the knowledge sources that newly graduated nurses use will inform both education and practice. Qualitative studies on newly graduated nurses' use of knowledge sources are increasing though generated from scattered healthcare contexts. Therefore, a metasynthesis of qualitative research on what knowledge sources new graduates use in decision-making was conducted. Meta-ethnography. Nineteen reports, representing 17 studies, published from 2000-2014 were identified from iterative searches in relevant databases from May 2013-May 2014. Included reports were appraised for quality and Noblit and Hare's meta-ethnography guided the interpretation and synthesis of data. Newly graduated nurses' use of knowledge sources during their first 2-year postgraduation were interpreted in the main theme 'self and others as knowledge sources,' with two subthemes 'doing and following' and 'knowing and doing,' each with several elucidating categories. The metasynthesis revealed a line of argument among the report findings underscoring progression in knowledge use and perception of competence and confidence among newly graduated nurses. The transition phase, feeling of confidence and ability to use critical thinking and reflection, has a great impact on knowledge sources incorporated in clinical decisions. The synthesis accentuates that for use of newly graduated nurses' qualifications and skills in evidence-based practice, clinical practice needs to provide a supportive environment which nurtures critical thinking and questions and articulates use of multiple knowledge sources. © 2016 John Wiley & Sons Ltd.

We investigated the association between antipsychotic medications and the risk of dental caries in patients with schizophrenia. We enroled a nationwide cohort of patients with newly diagnosed schizophrenia within 1 year of dental caries development. Exposure to antipsychotics and other medications was categorised according to their type and duration, and the association between exposure and dental caries was assessed through logistic regressions. Of the 3610 patients with newly diagnosed schizophrenia, 2149 (59.5%) exhibited an incidence of treated dental caries. Logistic regression analysis identified a younger age, female sex, high income, a 2-year history of dental caries, and exposure to first-generation antipsychotics, and antihypertensives as independent risk factors for treated dental caries in patients with schizophrenia. Hyposalivation, the adverse effect of first-generation antipsychotics and antihypertensives, was associated with an increased risk of treated dental caries. However, hypersalivation from first-generation antipsychotics for dental caries was associated with a protective factor. These findings suggest that clinicians should pay attention to the aforementioned risk factors for dental caries in patients with schizophrenia, particularly while prescribing first-generation antipsychotics and antihypertensives to such patients.

Full Text Available A newly dead cadaver simulation is practiced on the physical remains of the dead before the onset of rigor mortis. This technique has potential benefits for providing real-life in-situ experience for novice providers in health care practices. Evolving ethical views in health care brings into question some of the ethical aspects associated with newly dead cadaver simulation in terms of justification for practice, autonomy, consent, and the need of disclosure. A clear statement of policies and procedures on newly dead cadaver simulation has yet to be implemented. Although there are benefits and disadvantages to an in-situ cadaver simulation, such practices should not be carried out in secrecy as there is no compelling evidence that suggests such training as imperative. Secrecy in these practices is a violation of honor code of nursing ethics. As health care providers, practitioners are obliged to be ethically honest and trustworthy to their patients. The author explores the ethical aspects of using newly dead cadaver simulation in training novice nursing providers to gain competency in various lifesaving skills, which otherwise cannot be practiced on a living individual. The author explores multiple views on cadaver simulation in relation to ethical theories and practices such as consent and disclosure to family.

Evaluation of interim and final waste forms for the newly generated liquid low-level waste flowsheet

1996-05-01

The purpose of this review is to evaluate the final forms that have been proposed for radioactive-containing solid wastes and to determine their application to the solid wastes that will result from the treatment of newly generated liquid low-level waste (NGLLLW) and Melton Valley Storage Tank (MVST) supernate at the Oak Ridge National Laboratory (ORNL). Since cesium and strontium are the predominant radionuclides in NGLLLW and MVST supernate, this review is focused on the stabilization and solidification of solid wastes containing these radionuclides in cement, glass, and polymeric materials-the principal waste forms that have been tested with these types of wastes. Several studies have shown that both cesium and strontium are leached by distilled water from solidified cement, although the leachabilities of cesium are generally higher than those of strontium under similar conditions. The situation is exacerbated by the presence of sulfates in the solution, as manifested by cracking of the grout. Additives such as bentonite, blast-furnace slag, fly ash, montmorillonite, pottery clay, silica, and zeolites generally decrease the cesium and strontium release rates. Longer cement curing times (>28 d) and high ionic strengths of the leachates, such as those that occur in seawater, also decrease the leach rates of these radionuclides. Lower cesium leach rates are observed from vitrified wastes than from grout waste forms. However, significant quantities of cesium are volatilized due to the elevated temperatures required to vitrify the waste. Hence, vitrification will generally require the use of cleanup systems for the off-gases to prevent their release into the atmosphere

TRU [transuranic] waste certification compliance requirements for acceptance of newly generated contact-handled wastes to be shipped to the Waste Isolation Pilot Plant: Revision 2

International Nuclear Information System (INIS)

1989-01-01

Compliance requirements are presented for certifying that unclassified, newly generated (NG), contact-handled (CH) transuranic (TRU) solid wastes from defense programs meet the Waste Isolation Pilot Plant (WIPP) Waste Acceptance Criteria (WAC). Where appropriate, transportation and interim storage requirements are incorporated; however, interim storage sites may have additional requirements consistent with these requirements. All applicable Department of Energy (DOE) orders must continue to be met. The compliance requirements for stored or buried waste are not addressed in this document. The compliance requirements are divided into four sections, primarily determined by the general feature that the requirements address. These sections are General Requirements, Waste Container Requirements, Waste Form Requirements, and Waste Package Requirements. The waste package is the combination of waste container and waste. 10 refs., 1 fig

Cross-Linking Mast Cell Specific Gangliosides Stimulates the Release of Newly Formed Lipid Mediators and Newly Synthesized Cytokines

2016-01-01

Full Text Available Mast cells are immunoregulatory cells that participate in inflammatory processes. Cross-linking mast cell specific GD1b derived gangliosides by mAbAA4 results in partial activation of mast cells without the release of preformed mediators. The present study examines the release of newly formed and newly synthesized mediators following ganglioside cross-linking. Cross-linking the gangliosides with mAbAA4 released the newly formed lipid mediators, prostaglandins D2 and E2, without release of leukotrienes B4 and C4. The effect of cross-linking these gangliosides on the activation of enzymes in the arachidonate cascade was then investigated. Ganglioside cross-linking resulted in phosphorylation of cytosolic phospholipase A2 and increased expression of cyclooxygenase-2. Translocation of 5-lipoxygenase from the cytosol to the nucleus was not induced by ganglioside cross-linking. Cross-linking of GD1b derived gangliosides also resulted in the release of the newly synthesized mediators, interleukin-4, interleukin-6, and TNF-α. The effect of cross-linking the gangliosides on the MAP kinase pathway was then investigated. Cross-linking the gangliosides induced the phosphorylation of ERK1/2, JNK1/2, and p38 as well as activating both NFκB and NFAT in a Syk-dependent manner. Therefore, cross-linking the mast cell specific GD1b derived gangliosides results in the activation of signaling pathways that culminate with the release of newly formed and newly synthesized mediators.

Establishment probability in newly founded populations

Directory of Open Access Journals (Sweden)

Gusset Markus

2012-06-01

Full Text Available Abstract Background Establishment success in newly founded populations relies on reaching the established phase, which is defined by characteristic fluctuations of the population’s state variables. Stochastic population models can be used to quantify the establishment probability of newly founded populations; however, so far no simple but robust method for doing so existed. To determine a critical initial number of individuals that need to be released to reach the established phase, we used a novel application of the “Wissel plot”, where –ln(1 – P0(t is plotted against time t. This plot is based on the equation P0t=1–c1e–ω1t, which relates the probability of extinction by time t, P0(t, to two constants: c1 describes the probability of a newly founded population to reach the established phase, whereas ω1 describes the population’s probability of extinction per short time interval once established. Results For illustration, we applied the method to a previously developed stochastic population model of the endangered African wild dog (Lycaon pictus. A newly founded population reaches the established phase if the intercept of the (extrapolated linear parts of the “Wissel plot” with the y-axis, which is –ln(c1, is negative. For wild dogs in our model, this is the case if a critical initial number of four packs, consisting of eight individuals each, are released. Conclusions The method we present to quantify the establishment probability of newly founded populations is generic and inferences thus are transferable to other systems across the field of conservation biology. In contrast to other methods, our approach disaggregates the components of a population’s viability by distinguishing establishment from persistence.

Immune Response Generated With the Administration of Autologous Dendritic Cells Pulsed With an Allogenic Tumoral Cell-Lines Lysate in Patients With Newly Diagnosed Diffuse Intrinsic Pontine Glioma

Full Text Available Background and objectiveDiffuse intrinsic pontine glioma (DIPG is a lethal brainstem tumor in children. Dendritic cells (DCs have T-cell stimulatory capacity and, therefore, potential antitumor activity for disease control. DCs vaccines have been shown to reactivate tumor-specific T cells in both clinical and preclinical settings. We designed a phase Ib immunotherapy (IT clinical trial with the use of autologous dendritic cells (ADCs pulsed with an allogeneic tumors cell-lines lysate in patients with newly diagnosed DIPG after irradiation (radiation therapy.MethodsNine patients with newly diagnosed DIPG met enrollment criteria. Autologous dendritic cell vaccines (ADCV were prepared from monocytes obtained by leukapheresis. Five ADCV doses were administered intradermally during induction phase. In the absence of tumor progression, patients received three boosts of tumor lysate every 3 months during the maintenance phase.ResultsVaccine fabrication was feasible in all patients included in the study. Non-specific KLH (9/9 patients and specific (8/9 patients antitumor response was identified by immunologic studies in peripheral blood mononuclear cells (PBMC. Immunological responses were also confirmed in the T lymphocytes isolated from the cerebrospinal fluid (CSF of two patients. Vaccine administration resulted safe in all patients treated with this schema.ConclusionThese preliminary results demonstrate that ADCV preparation is feasible, safe, and generate a DIPG-specific immune response detected in PBMC and CSF. This strategy shows a promising backbone for future schemas of combination IT.

Infection of macaques with chimeric viruses based on SIVMAC but expressing the HIV-1 envelope (Env) glycoproteins (SHIVs) remains the most powerful model for evaluating prevention and therapeutic strategies against AIDS. Unfortunately, only a few SHIVs are currently available. Furthermore, their generation has required extensive adaptation of the HIV-1 Env sequences in macaques so they may not accurately represent HIV-1 Env proteins circulating in humans, potentially limiting their translational utility. We developed a strategy for generating large numbers of SHIV constructs expressing Env proteins from newly transmitted HIV-1 strains. By inoculating macaques with cocktails of multiple SHIV variants, we selected SHIVs that can replicate and cause AIDS-like disease in immunologically intact rhesus macaques without requiring animal-to-animal passage. One of these SHIVs could be transmitted mucosally. We demonstrate the utility of the SHIVs generated by this method for evaluating neutralizing antibody administration as a protection against mucosal SHIV challenge. Copyright © 2014 Elsevier Inc.

Synthesis of new proteins, a key step in the central dogma of molecular biology, has been a major biological process by which cells respond rapidly to environmental cues in both physiological and pathological conditions. However, the selective visualization of a newly synthesized proteome in living systems with subcellular resolution has proven to be rather challenging, despite the extensive efforts along the lines of fluorescence staining, autoradiography, and mass spectrometry. Herein, we report an imaging technique to visualize nascent proteins by harnessing the emerging stimulated Raman scattering (SRS) microscopy coupled with metabolic incorporation of deuterium-labeled amino acids. As a first demonstration, we imaged newly synthesized proteins in live mammalian cells with high spatial–temporal resolution without fixation or staining. Subcellular compartments with fast protein turnover in HeLa and HEK293T cells, and newly grown neurites in differentiating neuron-like N2A cells, are clearly identified via this imaging technique. Technically, incorporation of deuterium-labeled amino acids is minimally perturbative to live cells, whereas SRS imaging of exogenous carbon–deuterium bonds (C–D) in the cell-silent Raman region is highly sensitive, specific, and compatible with living systems. Moreover, coupled with label-free SRS imaging of the total proteome, our method can readily generate spatial maps of the quantitative ratio between new and total proteomes. Thus, this technique of nonlinear vibrational imaging of stable isotope incorporation will be a valuable tool to advance our understanding of the complex spatial and temporal dynamics of newly synthesized proteome in vivo.

Dodge, Robert L.; Montoya, Andy M.

2003-01-01

By the time the Waste Isolation Pilot Plant (WIPP) completes its Disposal Phase in FY 2034, the Department of Energy (DOE) will have disposed of approximately 109,378 cubic meters (m3) of Transuranic (TRU) waste in WIPP (1). If DOE adheres to its 2005 Pollution Prevention Goal of generating less than 141m3/yr of TRU waste, approximately 5000 m3 (4%) of that TRU waste will be newly generated (2). Because of the overwhelming majority (96%) of TRU waste destined for disposal at WIPP is legacy waste, the characterization and certification requirements were developed to resolve those issues related to legacy waste. Like many other DOE facilities Los Alamos National Laboratory (LANL) has a large volume (9,010m3) of legacy Transuranic Waste in storage (3). Unlike most DOE facilities LANL will generate approximately 140m3 of newly generated TRU waste each year3. LANL's certification program was established to meet the WIPP requirements for legacy waste and does not take advantage of the fundamental differences in waste knowledge between newly generated and legacy TRU waste

Seafood substitutions obscure patterns of mercury contamination in Patagonian toothfish (Dissostichus eleginoides or "Chilean sea bass".

Directory of Open Access Journals (Sweden)

Peter B Marko

Full Text Available Seafood mislabeling distorts the true abundance of fish in the sea, defrauds consumers, and can also cause unwanted exposure to harmful pollutants. By combining genetic data with analyses of total mercury content, we have investigated how species substitutions and fishery-stock substitutions obscure mercury contamination in Patagonian toothfish (Dissostichus eleginoides, also known as "Chilean sea bass". Patagonian toothfish show wide variation in mercury concentrations such that consumers may be exposed to either acceptable or unacceptable levels of mercury depending on the geographic origins of the fish and the allowable limits of different countries. Most notably, stocks of Patagonian toothfish in Chile accumulate significantly more mercury than stocks closer to the South Pole, including the South Georgia/Shag Rocks stock, a fishery certified by the Marine Stewardship Council (MSC as sustainably fished. Consistent with the documented geography of mercury contamination, our analysis showed that, on average, retail fish labeled as MSC-certified Patagonian toothfish had only half the mercury of uncertified fish. However, consideration of genetic data that were informative about seafood substitutions revealed a complex pattern of contamination hidden from consumers: species substitutions artificially inflated the expected difference in mercury levels between MSC-certified and uncertified fish whereas fishery stock substitutions artificially reduced the expected difference in mercury content between MSC-certified and uncertified fish that were actually D. eleginoides. Among MSC-certified fish that were actually D. eleginoides, several with exogenous mtDNA haplotypes (i.e., not known from the certified fishery had mercury concentrations on par with uncertified fish from Chile. Overall, our analysis of mercury was consistent with inferences from the genetic data about the geographic origins of the fish, demonstrated the potential negative impact of

Since 1970, defense-generated transuranic waste has been placed into 20-year retrievable storage at the Radioactive Waste Management Complex at the Idaho National Engineering Laboratory (INEL). A major objective of the US Department of Energy (DOE) Nuclear Waste Management Program is to remove all retrievably stored transuranic waste form the INEL. To support this objective, the Stored Waste Examination Pilot Plant (SWEPP) and the Process Experimental Pilot Plant (PREPP) are currently being constructed. SWEPP will certify waste, using nondestructive examination techniques, for shipment to the Waste Isolation Pilot Plant (WIPP). PREPP will process uncertifiable waste into a certifiable waste form. 3 references

Portfolio assessments for future generation investment in newly industrializing countries – A case study of Thailand

International Nuclear Information System (INIS)

Vithayasrichareon, Peerapat; MacGill, Iain F.

2012-01-01

This paper assesses future electricity generation portfolios in Thailand in 2030 given uncertain future fossil-fuel prices, carbon pricing policies, electricity demand, and capital costs. Thailand faces challenges for generation investment given its rapid socio-economic progress and fast growing demand. A novel generation investment and planning decision-support tool which incorporates a Monte Carlo extension to conventional optimal generation mix methods combined with portfolio-based analysis techniques, is used. The tool can formally assess tradeoffs between expected future generation costs, cost uncertainties, and CO 2 emissions for the range of different generation portfolios. Results highlight that different levels of future carbon pricing will have significant impacts on the most appropriate generation portfolios. The impact of carbon pricing, however, is not on the appropriate proportion of combined cycle gas turbines (CCGT) in the mix but, instead, on the future role of coal versus nuclear in Thailand. Compared with the current proposed 2030 generation mix, it is possible that there are other generation portfolios that offer lower expected costs, cost uncertainty, and CO 2 emissions depending on future carbon pricing. Results suggest that this investment decision-support approach may have value for electric utilities and policy-makers contemplating significant generation investments under high future uncertainty and conflicting policy objectives. -- Highlights: ► Assess Thailand's future generation portfolios in 2030 under uncertainties. ► Future carbon prices have significant impacts on the appropriate generation mixes. ► Carbon pricing affects the future role of coal versus nuclear in Thailand. ► There may be more appropriate alternatives than the proposed 2030 generation mix. ► This decision-support approach has value for utility and policy decision-making.

This review addresses the expected impact of newly sequenced genomes on antibacterial discovery and vaccinology. Also, it discusses...... heightened expectations that NGS would boost antibacterial discovery and vaccine development. Although many possible drug and vaccine targets have been discovered, the success rate of genome-based analysis has remained below expectations. Furthermore, NGS has had consequences for genome quality, resulting...

South Africa transformed higher education through the enactment of the Higher Education Act (No. 101 of 1997). The researcher identified the need to develop a model for the mentoring of newly-appointed nurse educators in nursing education institutions in South Africa.  To develop and describe the model for mentoring newly-appointed nurse educators in nursing education institutions in South Africa.  A qualitative and theory-generating design was used (following empirical findings regarding needs analysis) in order to develop the model. The conceptualisation of the framework focused on the context, content, process and the theoretical domains that influenced the model. Ideas from different theories were borrowed from and integrated with the literature and deductive and inductive strategies were applied.  The structure of the model is multidimensional and complex in nature (macro, mesoand micro) based on the philosophy of reflective practice, competency-based practice andcritical learning theories. The assumptions are in relation to stakeholders, context, mentoring, outcome, process and dynamic. The stakeholders are the mentor and mentee within an interactive participatory relationship. The mentoring takes place within the process with a sequence of activities such as relationship building, development, engagement, reflective process and assessment. Capacity building and empowerment are outcomes of mentoring driven by motivation.  The implication for nurse managers is that the model can be used to develop mentoring programmes for newly-appointed nurse educators.

The US education system must find creative and effective ways to foster the healthy development of the approximately 2 million newly arrived immigrant and refugee adolescents, many of whom contend with language barriers, limited prior education, trauma, and discrimination. We identify research priorities for promoting the school success of these youth. The study used the 4-phase priority-setting method of the Child Health and Nutrition Research Initiative. In the final stage, 132 researchers, service providers, educators, and policymakers based in the United States were asked to rate the importance of 36 research options. The highest priority research options (range 1 to 5) were: evaluating newcomer programs (mean = 4.44, SD = 0.55), identifying how family and community stressors affect newly arrived immigrant and refugee adolescents' functioning in school (mean = 4.40, SD = 0.56), identifying teachers' major stressors in working with this population (mean = 4.36, SD = 0.72), and identifying how to engage immigrant and refugee families in their children's education (mean = 4.35, SD = 0.62). These research priorities emphasize the generation of practical knowledge that could translate to immediate, tangible benefits for schools. Funders, schools, and researchers can use these research priorities to guide research for the highest benefit of schools and the newly arrived immigrant and refugee adolescents they serve. © 2017, American School Health Association.

There have been many studies reporting that newly formed bone around implants is spongy bone. However, although the morphology is reported as being like spongy bone, it is difficult to discriminate whether the bone quality of newly formed bone appears similar to osteoid or cortical bone; therefore, evaluation of bone quality is required. The aims of this study were to measure the bone mineral density (BMD) values of newly formed bone around implants after 4, 8, 16, 24 and 48 weeks, to represent these values on three-dimensional color mapping (3Dmap), and to evaluate the change in bone quality associated with newly formed bone around implants. The animal experimental protocol of this study was approved by the Ethics Committee for Animal Experiments of our University. This experiment used 20 surface treatment implants (Ti-6Al-4V alloy: 3.1 mm in diameter and 30.0 mm in length) by grit-blasting. They were embedded into surgically created flaws in femurs of 20 New Zealand white rabbits (16 weeks old, male). The rabbits were sacrificed with an ear intravenous overdose of pentobarbital sodium under general anesthesia each period, and the femurs were resected. We measured BMD of newly formed bone around implants and cortical bone using Micro-CT, and the BMD distribution map of 3Dmap (TRI/3D Bon BMD, Ratoc System Engineering). The BMD of cortical bone was 1,026.3±44.3 mg/cm 3 at 4 weeks, 1,023.8±40.9 mg/cm 3 at 8 weeks, 1,048.2±45.6 mg/cm 3 at 16 weeks, 1,067.2±60.2 mg/cm 3 at 24 weeks, and 1,069.3±50.7 mg/cm 3 at 48 weeks after implantation, showing a non-significant increase each period. The BMD of newly formed bone around implants was 296.8±25.6 mg/cm 3 at 4 weeks, 525.0±72.4 mg/cm 3 at 8 weeks, 691.2±26.0 mg/cm 3 at 16 weeks, 776.9±27.7 mg/cm 3 at 24 weeks, and 845.2±23.1 mg/cm 3 at 48 weeks after implantation, showing a significant increase after each period. It was revealed that the color scale of newly formed bone was Low level at 4 weeks, and then it

Newly discovered geological features and their potential impact on Darlington and Pickering

Newly available information reveals the presence of a prominent north-northeast oriented aeromagnetic lineament and east-northeast trending, linear patterns in young sediments on the bottom of Lake Ontario. The magnetic lineament, named the Niagara-Pickering Magnetic Lineament, passes practically beneath the Pickering Nuclear Generating Station (8x1600 MW reactors), and about 30 km west of the Darlington Nuclear Generating Station (4x2800 MW reactors). Magnetic data suggest that the Niagara-Pickering Magnetic Lineament may be the signature of a fault and may connect with the Akron Magnetic Boundary in Ohio, with which several earthquakes appear to be associated. Geological data lend support to the fault hypothesis. A north-northwest trending belt of earthquake epicenters, which includes the Lockport, NY earthquake (est M=5.0) and the Attica, NY earthquake (M=5.8), lies just east of, and parallels, the entire length of Georgian Bay en route to Attica, New York. The proximity and parallelism of the Georgian Bay Linear Zone to this belt of earthquake epicenters implies that the Georgian Bay Linear Zone may be tectonically active. The Georgian Bay Linear Zone and the Niagara-Pickering Magnetic Lineament appear to intersect very near Pickering and within about 30 km from Darlington. This, combined with evidence of high horizontal stresses in the area and the implication that both lineaments may be seismically active, suggests that many of the ingredients necessary for an earthquake of at least M=5.0 to M=6.25 exist near both Darlington and Pickering. Therefore, it is necessary that the Niagara-Pickering Magnetic Lineament, the Georgian Bay Linear Zone and the other newly discovered structural features be properly evaluated in order to determine whether or not the current Design Basis Seismic Ground Motions for Darlington and Pickering are adequate

This paper reports the findings from a study of newly qualified nurses and which subjects the nurses regarded as the most important in order to be able to live up to the requirements of clinical practice, and how they experience their potential for developing practical and moral skills, after the decrease in practical training. A qualitative approach guided the research process and the analysis of the data. The data was collected by participant observation and qualitative interviews with four nurses as informants. The conclusions made in this study are based on the statements and the observations of the newly qualified nurses. Our findings are discussed in relation to the Aristotelian concept and other relevant literature. The main message is that the newly qualified nurses did not feel equipped when they finished their training. This could be interpreted as a direct consequence of the decrease in practical training. Our study also underlines that the way nursing theory is perceived and taught is problematic. The interviews revealed that the nurses think that nursing theories should be applied directly in practice. This misunderstanding is probably also applicable to the teachers of the theories.

A significantly improved thermoelectric generator has been developed to provide electric power for NASA's Galileo Mission in 1982. Nominal power requirements for Galileo will be about 450 watts at BOL (Beginning of Life), and this will be furnished by two Selenide Isotope Generators (SIG) each powered by a Multi Hundred Watt (MHW) radioisotopic heat source. A Ground Demonstration System (GDS) of a nominal 100 w(e) features a 3M - produced selenide ring module around a shortened MHW-dimensioned electrical heat source, newly developed axially-grooved heat pipes on a disc-shaped radiator, and other innovations which will allow a full-sized generator's weight to be held at about 90 lbs

Newly Emerging Immune Checkpoints: Promises for Future Cancer Therapy

Directory of Open Access Journals (Sweden)

Robert J. Torphy

2017-12-01

Full Text Available Cancer immunotherapy has been a great breakthrough, with immune checkpoint inhibitors leading the way. Despite the clinical effectiveness of certain immune checkpoint inhibitors, the overall response rate remains low, and the effectiveness of immunotherapies for many tumors has been disappointing. There is substantial interest in looking for additional immune checkpoint molecules that may act as therapeutic targets for cancer. Recent advances during the last decade have identified several novel immune checkpoint targets, including lymphocyte activation gene-3 (LAG-3, B and T lymphocyte attenuator (BTLA, programmed death-1 homolog (PD-1H, T-cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domain (TIM-3/carcinoembryonic antigen cell adhesion molecule 1 (CEACAM1, and the poliovirus receptor (PVR-like receptors. The investigations into these molecules have generated promising results in preclinical studies. Herein, we will summarize our current progress and understanding of these newly-characterized immune checkpoints and their potential application in cancer immunotherapy.

Competitiveness of nuclear power generation

International Nuclear Information System (INIS)

Sumi, Yoshihiko

1998-01-01

In view of the various merits of nuclear power generation, Japanese electric utilities will continue to promote nuclear power generation. At the same time, however, it is essential to further enhance cost performance. Japanese electric utilities plan to reduce the cost of nuclear power generation, such as increasing the capacity factor, reducing operation and maintenance costs, and reducing construction costs. In Asia, nuclear power will also play an important role as a stable source of energy in the future. For those countries planning to newly introduce nuclear power, safety is the highest priority, and cost competitiveness is important. Moreover, financing will be an essential issue to be resolved. Japan is willing to support the establishment of nuclear power generation in Asia, through its experience and achievements. In doing this, support should not only be bilateral, but should include all nuclear nations around the Pacific rim in a multilateral support network. (author)

The lived experience of newly qualified radiographers (1950-1985): An oral history of radiography

International Nuclear Information System (INIS)

Decker, Sola

2009-01-01

The preparedness for practice of newly qualified healthcare professionals (including radiographers) has been the focus of attention in recent years as the practice environment continues to place great demands on its workforce. This paper reports an aspect of the findings from an oral history project on the career history of radiographers conducted as an academic research investigating the changes that have occurred in radiography and the impact these have had on the profession and the practice of radiography. The main focus of this paper is the lived experience of the informants of the oral history project as newly qualified radiographers. The findings are discussed in the context of current practice environment and developments in radiography. Analysis of the textual materials generated from informants' oral historical accounts, suggest radiographers trained in this time frame perceived their training as 'fit for purpose. The findings further suggest there is a general norm of 'get-on-with-it' as a coping strategy which is still prevalent in the profession today. The paper concludes by drawing on lessons that can be learned from the lived experiences of radiographers' oral historical accounts.

Lin, Y.; Wang, F.; Liu, B.

2018-05-01

Through parallelization, field programmable gate array (FPGA) can achieve unprecedented speeds in large-scale parallel Monte Carlo (LPMC) simulations. FPGA presents both new constraints and new opportunities for the implementations of random number generators (RNGs), which are key elements of any Monte Carlo (MC) simulation system. Using empirical and application based tests, this study evaluates all of the four RNGs used in previous FPGA based MC studies and newly proposed FPGA implementations for two well-known high-quality RNGs that are suitable for LPMC studies on FPGA. One of the newly proposed FPGA implementations: a parallel version of additive lagged Fibonacci generator (Parallel ALFG) is found to be the best among the evaluated RNGs in fulfilling the needs of LPMC simulations on FPGA.

Electricity generation costs by source, and costs and benefits by substitutions of generation source

International Nuclear Information System (INIS)

Akimoto, Keigo; Oda, Junichiro; Sano, Fuminori

2015-01-01

After Fukushima-daiichi nuclear power accident, the Japanese government assessed the electricity generation costs by source in 2011. However, the conditions have been changing, and this study newly assessed the generation costs by source using new data. The generation costs for coal, oil, gas, nuclear, PV and wind power for 2013 and 2030 were estimated. According to the analysis, coal power is the cheapest when climate change damage costs are not considered, and nuclear power is the cheapest when the climate damage costs are considered. However, under the competitive electricity market in which power companies tend to invest in power plants with short-term payback investment preference, power companies will recognize higher costs of nuclear power particularly under highly uncertain nuclear regulation policies and energy policies. The policies to reduce the uncertainties are very important. (author)

Being a team leader: newly registered nurses relate their experiences.

Science.gov (United States)

Ekström, Louise; Idvall, Ewa

2015-01-01

This paper presents a study that explores how newly qualified registered nurses experience their leadership role in the ward-based nursing care team. A nurse's clinical leadership affects the quality of care provided. Newly qualified nurses experience difficulties during the transition period from student to qualified professional and find it challenging to lead nursing care. Twelve nurses were interviewed and the transcribed texts analysed using qualitative content analysis to assess both manifest and latent content. Five themes were identified: feeling stranded; forming well-functioning teams; learning to lead; having the courage, strength, and desire to lead; and ensuring appropriate care. The findings indicate that many factors limit nurses' leadership but some circumstances are supportive. The leadership prerequisites for newly registered nurses need to improve, emphasizing different ways to create a supportive atmosphere that promotes professional development and job satisfaction. To increase nurse retention and promote quality of care, nurse managers need to clarify expectations and guide and support newly qualified nurses in a planned way. © 2013 John Wiley & Sons Ltd.

People newly in love are more responsive to positive feedback.

Science.gov (United States)

Brown, Cassandra L; Beninger, Richard J

2012-06-01

Passionate love is associated with increased activity in dopamine-rich regions of the brain. Increased dopamine in these regions is associated with a greater tendency to learn from reward in trial-and-error learning tasks. This study examined the prediction that individuals who were newly in love would be better at responding to reward (positive feedback). In test trials, people who were newly in love selected positive outcomes significantly more often than their single (not in love) counterparts but were no better at the task overall. This suggests that people who are newly in love show a bias toward responding to positive feedback, which may reflect a general bias towards reward-seeking.

Wilson, Brad; Spencer, Horace; Kortebein, Patrick

2012-04-01

To evaluate exercise recommendations in patients newly diagnosed with fibromyalgia. A retrospective chart review. A public university rheumatology clinic. Patients newly diagnosed with fibromyalgia (N = 122). Frequency and type of exercise recommendations. The mean (standard deviation) age of these patients with fibromyalgia was 45 ± 12 years; 91% were women. Exercise was recommended as part of the documented treatment plan in 47% of these patients (57/122); only 3 patients had a documented contraindication for exercise. Aquatic exercise was most frequently recommended (56% [32/57]), followed by combined aquatic-aerobic exercise (26% [15/57]), and, infrequently, aerobic exercise only (5% [3/57]); only 7% of these patients (4/57) were referred for physical therapy. The primary method of communication was verbal discussion (94% [54/57]). Although there is well-documented evidence that exercise is beneficial for patients with fibromyalgia, we found that less than half of patients with newly diagnosed fibromyalgia in our study were provided recommendations to initiate an exercise program as part of their treatment plan. Further investigation of these findings are warranted, including evaluation of other university and community rheumatology practices as well as that of other physicians caring for patients with fibromyalgia. However, our findings indicate that there appears to be an opportunity to provide more specific and practical education regarding the implementation of an exercise regimen for patients with newly diagnosed fibromyalgia. Physiatrists may be particularly well suited to manage the exercise component of patients with fibromyalgia because of their specialized training in exercise prescription.

Possible origin of Saturn's newly discovered outer ring

International Nuclear Information System (INIS)

Moehlmann, D.

1986-01-01

Within a planetogonic model the self-gravitationally caused formation of pre-planetary and pre-satellite rings from an earlier thin disk is reported. The theoretically derived orbital radii of these rings are compared with the orbital levels in the planetary system and the satellite systems of Jupiter, Saturn and Uranus. From this comparison it is concluded that at the radial position of Saturn's newly discovered outer ring an early pre-satellite ring of more or less evolved satellites could have existed. These satellites should have been disturbed in their evolution by the gravitation of the neighbouring massive satellite Titan. The comparison also may indicate similarities between the asteroidal belt and the newly discovered outer ring of Saturn

2018-01-01

The present study assessed the level of dentists' knowledge regarding oral cancer in the city of São Paulo, Brazil. A questionnaire was used to compare the level of knowledge among newly graduated and senior clinicians. A total of 20,154 e-mails were correctly delivered to the dentists registered in the database of the Regional Dentistry Council of São Paulo, and 477 (2.36%) responses were received. This sample consisted of 84 newly graduated clinicians and 105 senior clinicians. For the statistical analysis, the chi-square test and the logistic regression analysis were performed with α = 0.05, and the results were described herein. According to their knowledge level, the results were statistically different between the groups, since 19% of the newly graduated clinicians were evaluated with knowledge grade A (excellent) in comparison to 6.7% of the senior clinicians. In spite of the results indicated that newly graduated clinicians' knowledge regarding oral cancer was 2.1 times higher, 34.5% of the professionals in this group had regular or poor knowledge on the subject, and several questions relating to clinical characteristics and risk factors indicated that there still exist some knowledge gaps, demonstrating that there is a need for further studies and information activities addressing oral cancer.

Mechanical characterization tests of the X2-Gen fuel assembly and skeleton

International Nuclear Information System (INIS)

Kim, Hyung Kyu; Yoon, Kyung Ho; Lee, Kang Hee; Kim, Jae Yong; Lee, Young Ho; Kang, Heung Seok

2011-01-01

The KNF (KEPCO Nuclear Fuel) requested mechanical characterization tests of a fuel assembly and a skeleton of the X2-Gen fuel. The tests consisted of the lateral vibration and lateral/axial stiffness, lateral/axial impact and combined deflection tests carried out by using the FAMeCT (Fuel Assembly Mechanical Characterization Tester) in KAERI. The upper and lower core plate simulators were newly designed and manufactured because the fuel geometry of the X2-Gen was different from the KSNP type fuel assembly. In addition to this, the upper carriage was also revised with the LM guide system from the previous two guide rods system. Therefore, the axial and combined deflection tests were soundly executed. Each test was repeated twice to confirm the repeatability. The discrepancy from the repetition was small enough to be neglected. The mechanical characterization tests were accredited with the KOLAS (Korea Laboratory Accreditation Scheme) standard, and the certified test reports (lateral vibration, lateral/axial bending and lateral/axial impact) and the uncertified test report (combined deflection) were issued together with the current test result report

Competence of newly qualified registered nurses from a nursing college

BG Morolong

2005-09-01

Full Text Available The South African education and training system, through its policy of outcomesbased education and training, has made competency a national priority. In compliance to this national requirement of producing competent learners, the South African Nursing Council ( 1999 B require that the beginner professional nurse practitioners and midwives have the necessary knowledge, skills, attitudes and values which will enable them to render efficient professional service. The health care system also demands competent nurse practitioners to ensure quality in health care. In the light of competency being a national priority and a statutory demand, the research question that emerges is, how competent are the newly qualified registered nurses from a specific nursing college in clinical nursing education? A quantitative, non-experimental contextual design was used to evaluate the competence of newly qualified registered nurses from a specific nursing college. The study was conducted in two phases. The first phase dealt with the development of an instrument together with its manual through the conceptualisation process. The second phase focused on the evaluation of the competency of newly qualified nurses using the instrument based on the steps of the nursing process. A pilot study was conducted to test the feasibility of the items of the instrument. During the evaluation phase, a sample of twenty-six newly qualified nurses was selected by simple random sampling from a target population of thirty-six newly qualified registered nurses. However, six participants withdrew from the study. Data was collected in two general hospitals where the newly qualified registered nurses were working. Observation and questioning were used as data collection techniques in accordance with the developed instrument. Measures were taken to ensure internal validity and reliability of the results. To protect the rights of the participants, the researcher adhered to DENOSA’S (1998

Situation of nuclear power generation in Sweden

Energy Technology Data Exchange (ETDEWEB)

Sandstroem, S [Swedish Atomic Forum

1978-01-01

In Sweden, nuclear power generation was received initially favorably. In the end of 1960s, however, nuclear power generation got involved in the activities of environment preservation. Then, political parties became opposed to nuclear power generation, and now, the need of nuclear power generation itself is regarded as questionable. In the general election in 1976, the Government opposing the nuclear power generation won. As the result, the conditional nuclear power development law and the energy committee were set up. The committee composed of parliament members, experts, and representatives of enterprises and trade unions is to submit its report so that the parliament can prepare a new energy program in the fall of 1978.

Pachocka, Lucyna Małgorzata; Urbanik, Anna

2016-01-01

The treatment of intestinal stoma is often a difficult experience for patients and results in numerous problems in the physical, psychological and social aspects. Therefore, post-operative care of the patient with the newly appointed stoma should be taken by therapeutic team consisting of doctors, nurses, physiotherapists, dieticians, psychologists and social workers. Appropriate nutritional education of patients aims to improve their quality of life and to prevent from unpleasant ailments formed after the operation. The specific type of stoma may decide about certain dietary recommendations. The presented work provides a practical dietary recommendations for patients with newly appointed stoma.

Emotional cues can guide selective attention processes. However, emotional stimuli can both activate long-term memory representations reflecting general world knowledge and engage newly formed memory representations representing specific knowledge from the immediate past. Here, the self-completion feature of associative memory was utilized to assess the regulation of attention processes by newly-formed emotional memory. First, new memory representations were formed by presenting pictures depicting a person either in an erotic pose or as a portrait. Afterwards, to activate newly-built memory traces, edited pictures were presented showing only the head region of the person. ERP recordings revealed the emotional regulation of attention by newly-formed memories. Specifically, edited pictures from the erotic compared to the portrait category elicited an early posterior negativity and late positive potential, similar to the findings observed for the original pictures. A control condition showed that the effect was dependent on newly-formed memory traces. Given the large number of new memories formed each day, they presumably make an important contribution to the regulation of attention in everyday life.

Tricks of the trade: time management tips for newly qualified doctors.

Science.gov (United States)

Offiah, Gozie; Doherty, Eva

2018-03-01

The transition from medical student to doctor is an important milestone. The discovery that their time is no longer their own and that the demands of their job are greater than the time they have available is extremely challenging. At a recent surgical boot camp training programme, 60 first-year surgical trainees who had just completed their internship were invited to reflect on the lessons learnt regarding effective time management and to recommend tips for their newly qualified colleagues. They were asked to identify clinical duties that were considered urgent and important using the time management matrix and the common time traps encountered by newly qualified doctors. The surgical trainees identified several practical tips that ranged from writing a priority list to working on relationships within the team. These tips are generic and so applicable to all newly qualified medial doctors. We hope that awareness of these tips from the outset as against learning them through experience will greatly assist newly qualified doctors. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Although both nurse empowerment and competence are fundamental concepts of describing newly graduated nurses' professional development and job satisfaction, only few studies exist on the relationship between these concepts. Therefore, the purpose of this study was to determine how newly graduated nurses assess their empowerment and to clarify professional competence compared to other work-related factors. A descriptive, cross-sectional and correlational design was applied. The sample comprised newly graduated nurses (n = 318) in Finland. Empowerment was measured using the 19-item Qualities of an Empowered Nurse scale and the Nurse Competence Scale measured nurses' self-assessed generic competence. In addition to demographic data, the background data included employment sector (public/private), job satisfaction, intent to change/leave job, work schedule (shifts/business hours) and assessments of the quality of care in the workplace. The data were analysed statistically by using Spearman's correlation coefficient as well as the One-Way and Multivariate Analysis of Variance. Cronbach's alpha coefficient was used to estimate the internal consistency. Newly graduated nurses perceived their level of empowerment and competence fairly high. The association between nurse empowerment and professional competence was statistically significant. Other variables correlating positively to empowerment included employment sector, age, job satisfaction, intent to change job, work schedule, and satisfaction with the quality of care in the work unit. The study indicates competence had the strongest effect on newly graduated nurses' empowerment. New graduates need support and career opportunities. In the future, nurses' further education and nurse managers' resources for supporting and empowering nurses should respond to the newly graduated nurses' requisites for attractive and meaningful work.

Zhao, Kun; Lee, Calvin; Anda, Jaime; Wong, Gerard

2015-03-01

For monotrichous bacteria, Pseudomonas aeruginosa, after cell division, one daughter cell inherits the old flagellum from its mother cell, and the other grows a new flagellum during or after cell division. It had been shown that the new flagellum grows at the distal pole of the dividing cell when the two daughter cells haven't completely separated. However, for those daughter cells who grow new flagella after division, it still remains unknown at which pole the new flagellum will grow. Here, by combining our newly developed bacteria family tree tracking techniques with genetic manipulation method, we showed that for the daughter cell who did not inherit the old flagellum, a new flagellum has about 90% chances to grow at the newly formed pole. We proposed a model for flagellation of P. aeruginosa.

Does Teacher Preparation Matter? Evidence about Teacher Certification, Teach for America, and Teacher Effectiveness.

Directory of Open Access Journals (Sweden)

2005-10-01

Full Text Available Recent debates about the utility of teacher education have raised questions about whether certified teachers are, in general, more effective than those who have not met the testing and training requirements for certification, and whether some candidates with strong liberal arts backgrounds might be at least as effective as teacher education graduates. This study examines these questions with a large student-level data set from Houston, Texas that links student characteristics and achievement with data about their teachers' certification status, experience, and degree levels from 1995-2002. The data set also allows an examination of whether Teach for America (TFA candidates-recruits from selective universities who receive a few weeks of training before they begin teaching-are as effective as similarly experienced certified teachers. In a series of regression analyses looking at 4th and 5th grade student achievement gains on six different reading and mathematics tests over a six-year period, we find that certified teachers consistently produce stronger student achievement gains than do uncertified teachers. These findings hold for TFA recruits as well as others. Controlling for teacher experience, degrees, and student characteristics, uncertified TFA recruits are less effective than certified teachers, and perform about as well as other uncertified teachers. TFA recruits who become certified after 2 or 3 years do about as well as other certified teachers in supporting student achievement gains; however, nearly all of them leave within three years. Teachers' effectiveness appears strongly related to the preparation they have received for teaching.

The experience of learning to speak up: a narrative inquiry on newly graduated registered nurses.

Science.gov (United States)

Law, Bernice Yee-Shui; Chan, Engle Angela

2015-07-01

To explore the process of learning to speak up in practice among newly graduated registered nurses. Speaking up is an important aspect of communication to ensure patient safety within a healthcare team. However, nurses have reported being hesitant about speaking up or being unable to be heard, despite adopting various safety tools. A power differential could be a factor in their hesitation to speak up. While a large number of new graduates are employed in the lower rungs of the hospital hierarchy to resolve local and global nursing shortages, the process of their learning to speak up remains under-explored. The narrative concept of experience is addressed through the three-dimensional space of a narrative inquiry. Eighteen new graduates were recruited. Stories of experiences of speaking up emerged naturally during repeated unstructured interviews and ongoing email conversations with three participants. The complex process of learning to speak up is schematically represented. Three interrelated narrative threads were identified: (1) learning to speak up requires more than one-off training and safety tools, (2) mentoring speaking up in the midst of educative and miseducative experiences and (3) making public spaces safe for telling secret stories. Speaking up requires ongoing mentoring to see new possibilities for sustaining professional identities in the midst of miseducative experiences under the potential shaping of the Chinese culture and generational differences. Appreciative inquiry might be a new approach that can be used to promote positive cultural changes to encourage newly graduated registered nurses to learn to speak up to ensure patient safety. Cultivating a safe and open culture of communication and mentoring new graduates to speak up will benefit patient safety now and in the future by helping to retain committed patient advocates who could mentor future generations. © 2015 John Wiley & Sons Ltd.

Perceptions of the clinical competence of newly registered nurses in the North West province

Full Text Available The clinical competence of newly registered nurses relating to the care of individual Clients, depends on their ability to correlate theoretical knowledge learned in the classroom with practice and the development of clinical skills. Its foundation lies in the ability to identify and solve problems that emanate from critical thinking, analytical reasoning and reflective practice. It is clear that the quality of clinical exposure plays a leading role in the development of nursing professionals. Nursing skills alone cannot ensure quality care of clients without the application of theory. Facilitation of this theory to practice therefore remains an essential component of nursing education. This study was aimed at identifying areas of incompetence of newly registered nurses (1998- 2001 in the clinical area by determining the newly registered nurses1 and professional nurses1 perceptions of the competence of the newly registered nurses. A quantitative, non-experimental, descriptive survey was used to collect the data regarding the clinical competence of newly registered nurses (1998-2001.

In nuclear or shielding design analysis for reactors or other facilities, nuclear data are one of the primary importances. Research project for nuclear data evaluation and their effective applications has been continuously performed. The objectives of this project are (1) to compile the latest evaluated nuclear data files, (2) to establish their processing code systems, and (3) to evaluate the multi-group constant library using the newly compiled data files and the code systems. As the results of this project, the latest version of NJOY nuclear data processing system, NJOY91.38 which is capable of processing data in ENDF-6 format, was compiled and installed in Cyber 960-31(OS : NOS/VE) and HP710 workstation. A 50-group constant library for fast reactor was generated with NJOY91.38 using evaluated data from JEF-1 and benchmark test of this library was performed. The newly generated library has been found to do an excellent job of calculating integral quantities for fast critical assemblies and is expected to be positively used to develop fast reactors.

Avis, Mark; Mallik, Maggie; Fraser, Diane M

2013-11-01

Transition experiences of newly qualified midwives were examined in depth during the third phase of a UK evaluation study of midwifery education. The fitness to practise and the retention of newly qualified nursing and midwifery graduates are pressing concerns for health care managers. The advantages of preceptorship are reported in the literature but the content and timing of schemes remain unclear. A semi-structured diary was kept for up to 6 months by 35 newly qualified midwives in 18 work sites covering all countries in the UK. The preceptor and supervisor of midwives for each newly qualified midwife completed short questionnaires about their preceptee's performance, and a further sub-sample of newly qualified midwives and preceptors participated in a semi-structured interview. Data were analysed to elicit aspects of newly qualified midwives transition experiences. Findings confirm that structured preceptorship schemes are not widely available. Newly qualified midwives primarily obtained transition support from members of the midwifery team. Although perceived as competent, there is no demarcation point in becoming confident to practise as a registered practitioner. Implications for managers include the importance of a supportive culture within clinical teams for successful transition and the introduction of structured preceptorship schemes facilitated by appropriate rotation patterns. © 2012 John Wiley & Sons Ltd.

Harrison, Reema; McClean, Serwaa; Lawton, Rebecca; Wright, John; Kay, Clive

2014-09-01

Mentorship is an increasingly popular innovation from business and industry that is being applied in health-care contexts. This paper explores the concept of mentorship for newly appointed physicians in their first substantive senior post, and specifically its utilization to enhance patient safety. Semi-structured face to face and telephone interviews with Medical Directors (n = 5), Deputy Medical Directors (n = 4), and Clinical Directors (n = 6) from 9 acute NHS Trusts in the Yorkshire and Humber region in the north of England. A focused thematic analysis was used. A number of beneficial outcomes were associated with mentorship for newly appointed physicians including greater personal and professional support, organizational commitment, and general well-being. Providing newly appointed senior physicians with support through mentorship was considered to enhance the safety of patient care. Mentorship may prevent or reduce active failures, be used to identify threats in the local working environment, and in the longer term, address latent threats to safety within the organization by encouraging a healthier safety culture. Offering mentorship to all newly appointed physicians in their first substantive post in health care may be a useful strategy to support the development of their clinical, professional, and personal skills in this transitional period that may also enhance the safety of patient care.

Dynamic cluster generation for a fuzzy classifier with ellipsoidal regions.

Science.gov (United States)

Abe, S

1998-01-01

In this paper, we discuss a fuzzy classifier with ellipsoidal regions that dynamically generates clusters. First, for the data belonging to a class we define a fuzzy rule with an ellipsoidal region. Namely, using the training data for each class, we calculate the center and the covariance matrix of the ellipsoidal region for the class. Then we tune the fuzzy rules, i.e., the slopes of the membership functions, successively until there is no improvement in the recognition rate of the training data. Then if the number of the data belonging to a class that are misclassified into another class exceeds a prescribed number, we define a new cluster to which those data belong and the associated fuzzy rule. Then we tune the newly defined fuzzy rules in the similar way as stated above, fixing the already obtained fuzzy rules. We iterate generation of clusters and tuning of the newly generated fuzzy rules until the number of the data belonging to a class that are misclassified into another class does not exceed the prescribed number. We evaluate our method using thyroid data, Japanese Hiragana data of vehicle license plates, and blood cell data. By dynamic cluster generation, the generalization ability of the classifier is improved and the recognition rate of the fuzzy classifier for the test data is the best among the neural network classifiers and other fuzzy classifiers if there are no discrete input variables.

Technical development and its application on steam generator replacement

Morita, Sadahiko; Hanzawa, Katsumi; Sato, Hajime; Kannoto, Yasuo.

1995-01-01

Twenty-two PWR nuclear power plants are now under commercial operation in Japan. Eight of these plants are scheduled to have their steam generators replaced by up-graded units as a social responsibility for improved reliability, economy and easier maintenance. To carry out steam generator replacement, main coolant pipe cutting and restoration techniques, remote controlled welding machines and other remote controlled equipment, templating techniques with which the new steam generator primary nozzles will fit the existing primary pipes correctly were developed. An adequate training program was carried out to establish these techniques and they were then applied in replacement work on site. The steam generators of the three plants were replaced completely in 1994. These newly developed techniques are to be applied in upcoming plants and replaced plants will be much reliable. (author)

A newly developed snack effective for enhancing bone volume

2009-07-01

Full Text Available Abstract Background The incidence of primary osteoporosis is higher in Japan than in USA and European countries. Recently, the importance of preventive medicine has been gradually recognized in the field of orthopaedic surgery with a concept that peak bone mass should be increased in childhood as much as possible for the prevention of osteoporosis. Under such background, we have developed a new bean snack with an aim to improve bone volume loss. In this study, we examined the effects of a newly developed snack on bone volume and density in osteoporosis model mice. Methods Orchiectomy (ORX and ovariectomy (OVX were performed for C57BL/6J mice of twelve-week-old (Jackson Laboratory, Bar Harbar, ME, USA were used in this experiment. We prepared and given three types of powder diet e.g.: normal calcium diet (NCD, Ca: 0.9%, Clea Japan Co., Tokyo, Japan, low calcium diet (LCD, Ca: 0.63%, Clea Japan Co., and special diet (SCD, Ca: 0.9%. Eighteen weeks after surgery, all the animals were sacrified and prepared for histomorphometric analysis to quantify bone density and bone mineral content. Results As a result of histomorphometric examination, SCD was revealed to enhance bone volume irrespective of age and sex. The bone density was increased significantly in osteoporosis model mice fed the newly developmental snack as compared with the control mice. The bone mineral content was also enhanced significantly. These phenomena were revealed in both sexes. Conclusion It is shown that the newly developed bean snack is highly effective for the improvement of bone volume loss irrespective of sex. We demonstrated that newly developmental snack supplements may be a useful preventive measure for Japanese whose bone mineral density values are less than the ideal condition.

wangensteen s., johansson i.s., björkström m.e. & nordström g. (2010) Critical thinking dispositions among newly graduated nurses. Journal of Advanced Nursing66(10), 2170–2181. Aim The aim of the study was to describe critical thinking dispositions among newly graduated nurses in Norway, and to study whether background data had any impact on critical thinking dispositions. Background Competence in critical thinking is one of the expectations of nursing education. Critical thinkers are described as well-informed, inquisitive, open-minded and orderly in complex matters. Critical thinking competence has thus been designated as an outcome for judging the quality of nursing education programmes and for the development of clinical judgement. The ability to think critically is also described as reducing the research–practice gap and fostering evidence-based nursing. Methods A cross-sectional descriptive study was performed. The data were collected between October 2006 and April 2007 using the California Critical Thinking Disposition Inventory. The response rate was 33% (n= 618). Pearson’s chi-square tests were used to analyse the data. Results Nearly 80% of the respondents reported a positive disposition towards critical thinking. The highest mean score was on the Inquisitiveness subscale and the lowest on the Truth-seeking subscale. A statistically significant higher proportion of nurses with high critical thinking scores were found among those older than 30 years, those with university education prior to nursing education, and those working in community health care. Conclusion Nurse leaders and nurse teachers should encourage and nurture critical thinking among newly graduated nurses and nursing students. The low Truth-seeking scores found may be a result of traditional teaching strategies in nursing education and might indicate a need for more student-active learning models. PMID:20384637

Hexaploid tritordeum (H(ch)H(ch)AABB; 2n = 42) results from the cross between Hordeum chilense (H(ch)H(ch); 2n = 14) and cultivated durum wheat (Triticum turgidum ssp. durum (AABB; 2n = 28). Morphologically, tritordeum resembles the wheat parent, showing promise for agriculture and wheat breeding. Start Codon Targeted (SCoT) polymorphism is a recently developed technique that generates gene-targeted markers. Thus, we considered it interesting to evaluate its potential for the DNA fingerprinting of newly synthesized hexaploid tritordeums and their respective parents. In this study, 60 SCoT primers were tested, and 18 and 19 of them revealed SCoT polymorphisms in the newly synthesized tritordeum lines HT27 and HT22, respectively, and their parents. An analysis of the presence/absence of bands among tritordeums and their parents revealed three types of polymorphic markers: (i) shared by tritordeums and one of their parents, (ii) exclusively amplified in tritordeums, and (iii) exclusively amplified in the parents. No polymorphism was detected among individuals of each parental species. Three SCoT markers were exclusively amplified in tritordeums of lines HT22 and HT27, being considered as polyploidization-induced rearrangements. About 70% of the SCoT markers of H. chilense origin were not transmitted to the allopolyploids of both lines, and most of the SCoTs scored in the newly synthesized allopolyploids originated from wheat, reinforcing the potential use of tritordeum as an alternative crop.

Health problems of newly arrived migrants and refugees in Europe.

The number of migrants and refugees in Europe in the past few years has increased dramatically due to war, violence or prosecutions in their homeland. Migration may affect physical, mental and social health. The objective of this article is to assess migrants and refugees' health problems, and to recommend appropriate interventions. A PubMed search of published articles on health problems of newly arrived migrants and refugees was conducted from 2003 through 2016, focusing on the current refugee crisis in Europe. In addition to communicable diseases, such as respiratory, gastrointestinal and dermatologic infections, non-communicable diseases, including chronic conditions, mental and social problems, account for a significant morbidity burden in newly arrived migrants and refugees. Vaccine-preventable diseases are also of outmost importance. The appropriate management of newly arrived refugees and migrants' health problems is affected by barriers to access to health care including legal, communication, cultural and bureaucratic difficulties. There is diversity and lack of integration regarding health care provision across Europe due to policy differences between health care systems and social services. There is a notable burden of communicable and non-communicable diseases among newly arrived migrants and refugees. Provision of health care at reception and temporary centres should be integrated and provided by a multidisciplinary team Appropriate health care of migrants and refugees could greatly enhance their health and social status which will benefit also the host countries at large. © International Society of Travel Medicine, 2017.

Directory of Open Access Journals (Sweden)

Badrul Azhar

2015-01-01

Full Text Available The Roundtable on Sustainable Palm Oil (RSPO is responsible for the certification of palm oil producers that comply with sustainability standards. However, it is not known whether RSPO-certified plantations are effective in maintaining biodiversity. Focusing on Peninsular Malaysia, we show that both RSPO-certified plantations and uncertified large-scale plantations are characterized by very low levels of landscape heterogeneity. By contrast, heterogeneity measures were many times higher in palm oil producing smallholdings, despite their lack of RSPO certification. The low heterogeneity of large-scale oil palm plantations, including those certified by the RSPO, is likely to severely limit their value for biodiversity conservation. Uncertified smallholdings, in contrast, are much more heterogeneous and therefore hold substantially greater promise for the integration of palm oil production and biodiversity conservation than large-scale plantations. With oil palm agriculture further expanding, certification schemes should mandate producers to improve biodiversity conservation through landscape management that promotes greater landscape heterogeneity.

Effects of People-oriented Leadership and Subordinate Employability on Call Center Withdrawal Behaviors

Full Text Available Call-center employees are prone to lateness, absenteeism, and turnover because their jobs are low-wage, low-skill, and provoke high levels of stress. Thus, considerate supervisors achieve from them better performance and reduced turnover. This study tested in a Peruvian call center (N = 255 various hypotheses concerned with the effects of people-oriented leadership on withdrawal behaviors, their moderation by subordinate perceived employability, and the nature of the relationships between withdrawal behaviors. The evidence revealed independence of uncertified absenteeism from turnover intention, negative effects of people-oriented leadership on subordinate turnover intention regardless of subordinate level of employability, and leadership x employability crossover interactive effects on subordinate uncertified absenteeism. Since people-oriented supervision is associated with increased absenteeism among highly employable subordinates and decreased absenteeism among low-employability workers, the effects cancel each other. Thus, there is a need for understanding the underlying determinants as a pre-condition to deriving practical recommendations.

Ten patients with newly diagnosed, advanced prostatic cancer were treated with radiotherapy and hormone therapy to improve tumor control and survival. Eight patients with hormonally relapsed prostatic cancer were treated with radiotherapy to improve their quality of life. Local control of the tumor was achieved in 9 of 10 patients with newly diagnosed, advanced prostatic cancer. Five of eight patients with hormonally relapsed prostatic cancer obtained improved quality of life. Combined radiotherapy and hormone therapy were effective in the treatment of newly diagnosed, advanced prostatic cancer, and radiotherapy was useful for improving the quality of life of patients with hormonally relapsed prostatic cancer.

Wicher, Sarah A; Jacoby, David B; Fryer, Allison D

Ozone causes vagally mediated airway hyperreactivity and recruits inflammatory cells, including eosinophils, to lungs, where they mediate ozone-induced hyperreactivity 1 day after exposure but are paradoxically protective 3 days later. We aimed to test the role of newly divided eosinophils in ozone-induced airway hyperreactivity in sensitized and nonsensitized guinea pigs. Nonsensitized and sensitized guinea pigs were treated with 5-bromo-2-deoxyuridine (BrdU) to label newly divided cells and were exposed to air or ozone for 4 h. Later (1 or 3 days later), vagally induced bronchoconstriction was measured, and inflammatory cells were harvested from bone marrow, blood, and bronchoalveolar lavage. Ozone induced eosinophil hematopoiesis. One day after ozone, mature eosinophils dominate the inflammatory response and potentiate vagally induced bronchoconstriction. However, by 3 days, newly divided eosinophils have reached the lungs, where they inhibit ozone-induced airway hyperreactivity because depleting them with antibody to IL-5 or a TNF-α antagonist worsened vagally induced bronchoconstriction. In sensitized guinea pigs, both ozone-induced eosinophil hematopoiesis and subsequent recruitment of newly divided eosinophils to lungs 3 days later failed to occur. Thus mature eosinophils dominated the ozone-induced inflammatory response in sensitized guinea pigs. Depleting these mature eosinophils prevented ozone-induced airway hyperreactivity in sensitized animals. Ozone induces eosinophil hematopoiesis and recruitment to lungs, where 3 days later, newly divided eosinophils attenuate vagally mediated hyperreactivity. Ozone-induced hematopoiesis of beneficial eosinophils is blocked by a TNF-α antagonist or by prior sensitization. In these animals, mature eosinophils are associated with hyperreactivity. Thus interventions targeting eosinophils, although beneficial in atopic individuals, may delay resolution of airway hyperreactivity in nonatopic individuals. Copyright �

Many people with epilepsy report experiencing psychological difficulties such as anxiety, depression and neuropsychological deficits including memory problems. Research has shown that these difficulties are often present not only for people with chronic epilepsy but also for people with newly diagnosed epilepsy. Despite this, there are very few published interventions that detail means to help people with newly diagnosed epilepsy manage these problems. To identify and assess possible psychological and neuropsychological interventions for adults with newly diagnosed epilepsy. We searched the following databases on 30 June 2015: the Cochrane Epilepsy Group Specialized Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (Ovid), SCOPUS, PsycINFO, CINAHL, ClinicalTrials.gov and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). This review includes all randomised controlled trials, quasi-randomised controlled trials, prospective cohort controlled studies, and prospective before and after studies which include psychological or neuropsychological interventions for people with newly diagnosed epilepsy. We excluded studies that included people with epilepsy and any other psychological disorder or neurological condition. We excluded studies carried out which recruited only children. We used the standard methodological procedure expected by The Cochrane Collaboration. Two authors independently completed data extraction and risk of bias analysis. The results of this were cross-checked and third author resolved any discrepancies. In the event of missing data, we contacted the study authors. Meta-analysis was not completed due to differences in the intervention and outcomes reported in the two studies. We included two randomised controlled trials assessing psychological interventions for people with newly diagnosed epilepsy. One study assessed a cognitive behavioural intervention (CBI) in an adolescent

Patients newly diagnosed with cancer are often confronted with feelings of uncertainty and life threat. A significant proportion may report impairments in psychosocial well-being. Previous studies examining protective psychological factors such as hope and emotion regulation (ER) have yet to investigate these processes concurrently within a common self-regulation framework and/or focus on newly diagnosed patients. The present study aimed to examine how hope and ER may relate to psychosocial outcomes of patients newly diagnosed with cancer. The present study used a cross-sectional design with self-report questionnaires. Participants were newly diagnosed patients (N = 101) recruited from three cancer therapy clinics in a hospital. Patients completed measures of hope, ER (cognitive reappraisal and expressive suppression), and psychosocial well-being (life satisfaction and negative affectivity). Findings showed that (1) hope and reappraisal, but not suppression, were associated with well-being and (2) the interaction between hope and reappraisal was associated with well-being; reappraisal was not associated with well-being in high hope patients, while high reappraisal was associated with better well-being in low hope patients. Individual differences in hope and reappraisal appeared to be associated with psychosocial outcomes in newly diagnosed cancer patients. Hopeful thinking appeared to benefit patients' psychosocial well-being. In addition, an interaction effect between hope and reappraisal suggested that reappraisal as an ER strategy may be particularly adaptive for patients with low hope.

The generation of oligodendroglial cells is preserved in the rostral migratory stream during aging

Directory of Open Access Journals (Sweden)

Vivian eCapilla-Gonzalez

2013-09-01

Full Text Available The subventricular zone (SVZ is the largest source of newly generated cells in the adult mammalian brain. SVZ-derived neuroblasts migrate via the rostral migratory stream (RMS to the olfactory bulb (OB, where they differentiate into mature neurons. Additionally, a small proportion of SVZ-derived cells contribute to the generation of myelinating oligodendrocytes. The production of new cells in the SVZ decreases during aging, affecting the incorporation of new neurons into the OB. However, the age-related changes that occur across the RMS are not fully understood. In this study we evaluate how aging affects the cellular organization of migrating neuroblast chains, the proliferation, and the fate of the newly generated cells in the SVZ-OB system. By using electron microscopy and immunostaining, we found that the RMS path becomes discontinuous and its cytoarchitecture is disorganized in aged mice (24-month-old mice. Subsequently, OB neurogenesis was impaired in the aged brain while the production of oligodendrocytes was not compromised. These findings provide new insight into oligodendrocyte preservation throughout life. Further exploration of this matter could help the development of new strategies to prevent neurological disorders associated with senescence.

To map current selection and recruitment processes for newly qualified nurses and to explore the advantages and limitations of current selection and recruitment processes. The need to improve current selection and recruitment practices for newly qualified nurses is highlighted in health policy internationally. A cross-sectional, sequential-explanatory mixed-method design with 4 components: (1) Literature review of selection and recruitment of newly qualified nurses; and (2) Literature review of a public sector professions' selection and recruitment processes; (3) Survey mapping existing selection and recruitment processes for newly qualified nurses; and (4) Qualitative study about recruiters' selection and recruitment processes. Literature searches on the selection and recruitment of newly qualified candidates in teaching and nursing (2005-2013) were conducted. Cross-sectional, mixed-method data were collected from thirty-one (n = 31) individuals in health providers in London who had responsibility for the selection and recruitment of newly qualified nurses using a survey instrument. Of these providers who took part, six (n = 6) purposively selected to be interviewed qualitatively. Issues of supply and demand in the workforce, rather than selection and recruitment tools, predominated in the literature reviews. Examples of tools to measure values, attitudes and skills were found in the nursing literature. The mapping exercise found that providers used many selection and recruitment tools, some providers combined tools to streamline process and assure quality of candidates. Most providers had processes which addressed the issue of quality in the selection and recruitment of newly qualified nurses. The 'assessment centre model', which providers were adopting, allowed for multiple levels of assessment and streamlined recruitment. There is a need to validate the efficacy of the selection tools. © 2014 John Wiley & Sons Ltd.

To explore newly graduated nurses' occupational commitment and its associations with their self-assessed professional competence and other work-related factors. As a factor affecting nurse turnover, newly graduated nurses' occupational commitment and its associations with work-related factors needs exploring to retain adequate workforce. Nurses' commitment has mainly been studied as organisational commitment, but newly graduated nurses' occupational commitment and its association with work-related factors needs further studying. This study used descriptive, cross-sectional, correlation design. A convenience sample of 318 newly graduated nurses in Finland participated responding to an electronic questionnaire. Statistical software, NCSS version 9, was used in data analysis. Frequencies, percentages, ranges, means and standard deviations summarised the data. Multivariate Analyses of Variance estimated associations between occupational commitment and work-related variables. IBM SPSS Amos version 22 estimated the model fit of Occupational Commitment Scale and Nurse Competence Scale. Newly graduated nurses' occupational commitment was good, affective commitment reaching the highest mean score. There was a significant difference between the nurse groups in favour of nurses at higher competence levels in all subscales except in limited alternatives occupational commitment. Multivariate analyses revealed significant associations between subscales of commitment and competence, turnover intentions, job satisfaction, earlier professional education and work sector, competence counting only through affective dimension. The association between occupational commitment and low turnover intentions and satisfaction with nursing occupation was strong. Higher general competence indicated higher overall occupational commitment. Managers' recognition of the influence of all dimensions of occupational commitment in newly graduated nurses' professional development is important. Follow

Malnutrition is common among patients with cancer, but little attention is given to its risks and consequences. The aim of this study is to assess the nutritional status and identify the factors associated with malnutrition among newly diagnosed patients with cancer. Patients admitted with newly diagnosed cancer at a teaching hospital in Malaysia were recruited from January to April 2015. Nutritional status was assessed before treatment initiation, and patients were classified into three categories. A total of 132 pretreatment patients were recruited into the study. About half were severely malnourished. Patients with stage III cancer had the highest prevalence of severe malnourishment. Clinical parameters and disease characteristics were significantly associated with nutritional status. Demographic variables were also statistically significantly associated with severe nutritional status.

Assessment of metal retention in newly constructed highway embankments.

Werkenthin, Moritz; Kluge, Björn; Wessolek, Gerd

2016-12-01

Newly constructed embankments should provide both a specific bearing capacity to enable trafficability in emergency cases and a sufficient pollutant retention capacity to protect the groundwater. A number of lysimeters were installed along the A115 highway to determine total and dissolved metal concentrations in road runoff and in the soil solution of newly constructed embankments. Dissolved concentrations in soil solution of the embankments did not exceed the trigger values of the German legislation. Depending on the metal, total concentrations in soil solution were more than twice as high as dissolved concentrations. The high infiltration rates lead to increased groundwater recharge beneath the embankments (up to 4100 mm a -1 ). Although metal concentrations were not problematic from the legislators' point of view, the elevated infiltration rates beside the road facilitated the transfer of high metal loads into deeper soil layers and potentially into the groundwater as well.

2016-01-01

Due to improved understanding of the role of bone morphogenetic protein 4 (BMP4) in an increasing number of diseases, the development of selective inhibitors of BMP4 is an attractive therapeutic option. The currently available BMP4 inhibitors are not suitable as therapeutics because of their low specificity and low effectiveness. Here, we compared newly generated anti-BMP4 llama-derived antibodies (VHHs) with 3 different types of commercially available BMP4 inhibitors, natural antagonists, small molecule BMPR inhibitors and conventional anti-BMP4 monoclonal antibodies. We found that the anti-BMP4 VHHs were as effective as the natural antagonist or small molecule inhibitors, but had higher specificity. We also showed that commercial anti-BMP4 antibodies were inferior in terms of both specificity and effectiveness. These findings might result from the fact that the VHHs C4C4 and C8C8 target a small region within the BMPR1 epitope of BMP4, whereas the commercial antibodies target other areas of the BMP4 molecule. Our results show that the newly developed anti-BMP4 VHHs are promising antibodies with better specificity and effectivity for inhibition of BMP4, making them an attractive tool for research and for therapeutic applications.

The purpose of this study was to examine the prevalence of workplace violence toward newly licensed nurses and the relationship between workplace violence and job outcomes. An online survey was conducted of newly licensed registered nurses who had obtained their license in 2012 or 2013 in South Korea and had been working for 5-12 months after first being employed. The sample consisted of 312 nurses working in hospitals or clinics. The Copenhagen Psychosocial Questionnaire II was used to measure violence and nurse job outcomes. Multiple linear and logistic regression analyses were conducted to examine the relationship between violence and job outcomes. Verbal abuse was most prevalent (59.6%), followed by threats of violence (36.9%), physical violence (27.6%), bullying (25.6%), and sexual harassment (22.4%). Approximately three quarters of the nurses had experienced at least one type of violence. The main perpetrators were patients and nurse colleagues, although the distribution of perpetrators varied depending on the type of violence. Bullying had a significant relationship with all four job outcomes (job satisfaction, burnout, commitment to the workplace, and intent to leave), while verbal abuse was associated with all job outcomes except for intent to leave. Violence perpetrated by nurse colleagues had a significant relationship with all four job outcomes, while violence by physicians had a significant inverse relationship with job satisfaction. Workplace violence is experienced by a high percentage of newly licensed nurses, and is associated with their job outcomes. Copyright © 2016. Published by Elsevier B.V.

Vibration power generator for a linear MR damper

International Nuclear Information System (INIS)

Sapiński, Bogdan

2010-01-01

The paper describes the structure and the results of numerical calculations and experimental tests of a newly developed vibration power generator for a linear magnetorheological (MR) damper. The generator consists of permanent magnets and coil with foil winding. The device produces electrical energy according to Faraday's law of electromagnetic induction. This energy is applied to vary the damping characteristics of the MR damper attached to the generator by the input current produced by the device. The objective of the numerical calculations was to determine the magnetic field distribution in the generator as well as the electric potential and current density in the generator's coil during the idle run and under the load applied to the MR damper control coil. The results of the calculations were used during the design and manufacturing stages of the device. The objective of the experimental tests carried out on a dynamic testing machine was to evaluate the generator's efficiency and to compare the experimental and predicted data. The experimental results demonstrate that the engineered device enables a change in the kinetic energy of the reciprocal motion of the MR damper which leads to variations in the damping characteristics. That is why the generator may be used to build up MR damper based vibration control systems which require no external power

A description of the two-dimensional mesh generation program, LOOM-P, is given in detail. The program is developed newly to produce a mesh network for a reactor core geometry with the help of an automatic mesh generation routine built in it, under the control of the refresh-type graphic display. It is therefore similar to the edit program of the self-organizing mesh generator, QMESH-RENUM. Additional techniques are incorporated to improve the pattern of mesh elements by means of on-line conversational mode. The obtained mesh network is edited out as input data to the three-dimensional neutron diffusion theory code, FEM-BABEL. (auth.)

Sakamoto, Masayuki; Kageyama, Ryoichiro; Imayoshi, Itaru

2014-01-01

The olfactory bulb (OB) is the first central processing center for olfactory information connecting with higher areas in the brain, and this neuronal circuitry mediates a variety of odor-evoked behavioral responses. In the adult mammalian brain, continuous neurogenesis occurs in two restricted regions, the subventricular zone (SVZ) of the lateral ventricle and the hippocampal dentate gyrus. New neurons born in the SVZ migrate through the rostral migratory stream and are integrated into the neuronal circuits of the OB throughout life. The significance of this continuous supply of new neurons in the OB has been implicated in plasticity and memory regulation. Two decades of huge investigation in adult neurogenesis revealed the biological importance of integration of new neurons into the olfactory circuits. In this review, we highlight the recent findings about the physiological functions of newly generated neurons in rodent OB circuits and then discuss the contribution of neurogenesis in the brain function. Finally, we introduce cutting edge technologies to monitor and manipulate the activity of new neurons.

2008-01-01

The gravity-mode (g-mode) eigenfrequencies of newly born strange quark stars (SQSs) and neutron stars (NSs) are studied. It is found that the eigenfrequencies in SQSs are much lower than those in NSs by almost 1 order of magnitude, since the components of a SQS are all extremely relativistic particles while nucleons in a NS are nonrelativistic. We therefore propose that newly born SQSs can be distinguished from the NSs by detecting the eigenfrequencies of the g-mode pulsations of supernovae cores through gravitational radiation by LIGO-class detectors

A new model of event and message driven Petri network(EMDPN) based on the characteristic of class interaction for messages passing between two objects was extended. Using EMDPN interaction graph, a class hierarchical test-case generation algorithm with cooperated paths (copaths) was proposed, which can be used to solve the problems resulting from the class inheritance mechanism encountered in object-oriented software testing such as oracle, message transfer errors, and unreachable statement. Finally, the testing sufficiency was analyzed with the ordered sequence testing criterion(OSC). The results indicate that the test cases stemmed from newly proposed automatic algorithm of copaths generation satisfies synchronization message sequences testing criteria, therefore the proposed new algorithm of copaths generation has a good coverage rate.

Longitudinal trends and subgroup analysis in publication patterns for preclinical data of newly approved drugs.

Science.gov (United States)

Köster, Ursula; Nolte, Ingo; Michel, Martin C

2016-02-01

Having observed a large variation in the number and type of original preclinical publications for newly registered drugs, we have explored whether longitudinal trends and/or factors specific for certain drugs or their manufacturers may explain such variation. Our analysis is based on 1954 articles related to 170 newly approved drugs. The number of preclinical publications per compound declined from a median of 10.5 in 1991 to 3 in 2011. A similar trend was observed for the number of in vivo studies in general, but not in the subset of in vivo studies in animal models of disease. The percentage of compounds with studies using isolated human cells or cell lines almost doubled over time from 37 to 72%. Number of publications did not exhibit major differences between compounds intended for human versus veterinary use, therapeutic areas, small molecules versus biologicals, or innovator versus follow-up compounds; however, some companies may publish fewer studies per compound than others. However, there were qualitative differences in the types of models being used depending on the therapeutic area; specifically, compounds for use in oncology very often used isolated cells and cell lines, often from human origin. We conclude that the large variation in number and type of reported preclinical data is not easily explained. We propose that pharmaceutical companies should consistently provide a comprehensive documentation of the preclinical data they generate as part of their development programs in the public domain to enable a better understanding of the drugs they intend to market.

To study the psycho-social risk factors of sexual failure among newly married young males in the Uyghur population. We conducted a paired case control study of 186 newly married Uyghur young males (aged 17－30 ［23.4±2.9］ yr) with sexual failure and another 186 (aged 18－34 ［24.0±3.1］ yr) with no such problem as controls. We performed a logistic regression analysis on the possible psycho-social risk factors of this condition. Logistic regression analysis showed that the risk factors of sexual failure among the newly married men included personality (OR=0.271, 95% CI 0.176－0.420), income (OR=0.391, 95% CI 0.264－0.580), history of masturbation (OR=0.824, 95% CI 0.710－0.956), premarital sex (OR=0.757, 95% CI 0.677－0.847), sense of obligation (OR=1.756, 95% CI 1.157－2.693), equality of the social status (OR=0.574, 95% CI 0.435－0.756), degree of mutual care (OR=1.605, 95% CI 1.268－2.032), female's psychological obstacle (OR=2.832, 95% CI 1.221－6.569), and religion (OR=0.643, 95% CI 0.472－0.967). There was a statistical significance in the correlation between these factors and sexual failure in the newly married males (all Ppsycho-social factors, which necessitates sexual education among young males and particularly pre-marriage sexual education and psychological guide among both males and females.

Kim, Yunmi; You, Sunju; Kim, Jinhyun

2017-12-01

This study aimed to analyze the impact of increasing the supply of newly licensed nurses on improving the hospital nurse staffing grades for the period of 2009~2014. Using public administrative data, we analyzed the effect of newly licensed nurses on staffing in 1,594 hospitals using Generalized Estimating Equation (GEE) ordered logistic regression, and of supply variation on improving staffing grades in 1,042 hospitals using GEE logistic regression. An increase of one newly licensed nurse per 100 beds in general units had significantly lower odds of improving staffing grades (grades 6~0 vs. 7) (odds ratio=0.95, p=.005). The supply of newly licensed nurses increased by 32% from 2009 to 2014, and proportion of hospitals whose staffing grade had improved, not changed, and worsened was 19.1%, 70.1%, and 10.8% respectively. Compared to 2009, the supply variation of newly licensed nurses in 2014 was not significantly related to the increased odds of improving staffing grades in the region (OR=1.02, p=.870). To achieve a balance in the regional supply and demand for hospital nurses, compliance with nurse staffing legislation and revisions in the nursing fee differentiation policy are needed. Rather than relying on increasing nurse supply, retention policies for new graduate nurses are required to build and sustain competent nurse workforce in the future. © 2017 Korean Society of Nursing Science

Kicka, L; Machrafi, R; Miller, A

2017-12-01

Neutron fields in the vicinity of the newly built neutron facility, at the University of Ontario Institute of Technology (UOIT), have been investigated in a series of Monte Carlo simulations and measurements. The facility hosts a P-385 neutron generator based on a deuterium-deuterium fusion reaction. The neutron fluence at different locations around the neutron generator facility has been simulated using MCNPX 2.7E Monte Carlo particle transport program. To characterize neutron fields, three neutron sources were modeled with distributions corresponding to different incident deuteron energies of 90kV, 110kV, and 130kV. Measurements have been carried out to determine the dose rate at locations adjacent to the generator using bubble detectors (BDs). The neutron intensity was evaluated and the total dose rates corresponding to different applied acceleration potentials were estimated at various locations. Copyright © 2017 Elsevier Ltd.

Hope is important to cancer patients as it helps them deal with their diagnosis. Little is known about hope in newly diagnosed cancer patients. Based on the Transcending Possibilities conceptual model of hope, the purpose of this study was to examine the relationship of hope with pain, energy, and psychological and demographic characteristics in newly diagnosed adult oncology outpatients. Data from 310 New Patient Assessment Forms from cancer outpatients' health records were collected. Health records from the first six months of 2009 were reviewed and data were collected on hope, energy, pain, depression, anxiety, feeling overwhelmed, and demographic variables. A generalized linear modeling approach was used to study the relationship of hope scores with these variables. Hypothesized variables and variables that were significant at the P = 0.01 level from the univariate analysis were entered into the multivariate model, with hope scores as the dependent variable. Hope scores were significantly negatively related to age (P = 0.02). More specifically, oncology patients who were 65 years of age or older had significantly less hope than those under the age of 65 years (P = 0.01). Gender (P = 0.009) also was a significant factor, with men having higher hope scores than women. No other variables were significant. Older adults comprise the majority of persons in Canada with cancer. The lower hope scores found in this age group compared with their younger counterparts underscore the importance of further research. This study provides a foundation for future research in this important area for oncology patients. Copyright © 2013 U.S. Cancer Pain Relief Committee. Published by Elsevier Inc. All rights reserved.

Bellon, Jennifer R; Eglinton, Jeffery M; Siebert, Tracey E; Pollnitz, Alan P; Rose, Louisa; de Barros Lopes, Miguel; Chambers, Paul J

2011-08-01

Increasingly, winemakers are looking for ways to introduce aroma and flavour diversity to their wines as a means of improving style and increasing product differentiation. While currently available commercial yeast strains produce consistently sound fermentations, there are indications that sensory complexity and improved palate structure are obtained when other species of yeast are active during fermentation. In this study, we explore a strategy to increase the impact of non-Saccharomyces cerevisiae inputs without the risks associated with spontaneous fermentations, through generating interspecific hybrids between a S. cerevisiae wine strain and a second species. For our experiments, we used rare mating to produce hybrids between S. cerevisiae and other closely related yeast of the Saccharomyces sensu stricto complex. These hybrid yeast strains display desirable properties of both parents and produce wines with concentrations of aromatic fermentation products that are different to what is found in wine made using the commercial wine yeast parent. Our results demonstrate, for the first time, that the introduction of genetic material from a non-S. cerevisiae parent into a wine yeast background can impact favourably on the wine flavour and aroma profile of a commercial S. cerevisiae wine yeast.

  Professional commitment, or one's affinity and loyalty to a career, has become a topic of interest in athletic training. The expanding research on the topic, however, has omitted newly credentialed athletic trainers (ATs). For an impressionable group of practitioners, transitioning to clinical practice can be stressful.   To explore the professional commitment of newly credentialed ATs in the secondary school setting.   Secondary school.   Qualitative study.   A total of 31 newly credentialed ATs (6 men, 25 women; mean age = 24 ± 3 years) participated. Of these, 17 ATs (4 men, 13 women; mean age = 25 ± 4 years) were employed full time in the secondary school setting, and 14 ATs (2 men, 12 women; mean age = 23.0 ± 2.0 years) were graduate assistant students in the secondary school setting.   All participants completed semistructured interviews, which focused on their experiences in the secondary school setting and transitioning into the role and setting. Transcripts were analyzed using the phenomenologic approach. Creditability was established by peer review, member checks, and researcher triangulation.   Four main findings related to the professional commitment of newly credentialed ATs in the secondary school setting were identified. Work-life balance, professional relationships formed with the student-athletes, enjoyment gained from working in the secondary school setting, and professional responsibility emerged as factors facilitating commitment.   Affective commitment is a primary facilitator of professional commitment. Newly credentialed ATs who enjoy their jobs and have time to engage in nonwork roles are able to maintain a positive professional commitment. Our findings align with the previous literature and help strengthen our understanding that rejuvenation and passion are important to professional commitment.

Sulawesi microplate Island is located at famous triple junction area of the Eurasian, India-Australian, and Philippine Sea plates. Under the influence of the northward moving Australian plate and the westward motion of the Philippine plate, the island at Eastern part of Indonesia is collide and with the Eurasian plate and Sunda Block. Those recent microplate tectonic motions can be quantitatively determine by GNSS-GPS measurement. We use combine GNSS-GPS observation types (campaign type and continuous type) from 1997 to 2015 to derive newly velocity field of the area. Several strategies are applied and tested to get the optimum result, and finally we choose regional strategy to reduce error propagation contribution from global multi baseline processing using GAMIT/GLOBK 10.5. Velocity field are analyzed in global reference frame ITRF 2008 and local reference frame by fixing with respect alternatively to Eurasian plate - Sunda block, India-Australian plate and Philippine Sea plates. Newly results show dense distribution of velocity field. This information is useful for tectonic deformation studying in geospatial era.

Newly patented process enables low-cost solution for increasing white light spectrum of LEDs

Science.gov (United States)

Spanard, Jan-Marie

2017-10-01

A newly patented process for completing the spectral light array emitted by LED bulbs provides a low-cost method for producing better human centered lighting (HCL). This process uses non-luminescent colorant filters, filling out the jagged LED spectral emission into a full, white light array. While LED bulbs have the distinct economic advantages of using less energy, producing less heat and lasting years longer than traditional incandescent bulbs, the persistent metameric failure of LED bulbs has resulted in slower, and sometimes reluctant, adoption of LED lighting by the residential, retail and architectural markets. Adding missing wavelengths to LED generated bulbs via colorant filters increases the aesthetic appeal of the light by decreasing current levels of metameric failure, reducing the `flatness', `harshness', and `dullness' of LED generated light reported by consumers. LED phosphor-converted light can be successfully tuned to "whiter" white light with selective color filtering using permanent, durable transparent pigments. These transparent pigments are selectively applied in combination with existing manufacturing technologies and utilized as a final color-tuning step in bulb design. The quantity of emitted light chosen for color filtering can be adjusted from 1% to 100% of emitted light, creating a custom balance of light quantity with light quality. This invention recognizes that "better light" is frequently chosen over "more light" in the consumer marketplace.

To demonstrate the biodegradation of dibenzofuran (DF) and its structural analogs by a newly isolated Agrobacterium sp. PH-08. To assess the biodegradation potential of newly isolated Agrobacterium sp. PH-08, various substrates were evaluated as sole carbon sources in growth and biotransformation experiments. ESI LC-MS/MS analysis revealed the presence of angular degrading by-products as well as lateral dioxygenation metabolites in the upper pathway. The metabolites in the lower pathway also were detected. In addition, the cometabolically degraded daughter compounds of DF-related compounds such as BP and dibenzothiophene (DBT) in dual substrate degradation were observed. Strain PH-08 exhibited the evidence of meta-cleavage pathway as confirmed by the activity and gene expression of catechol-2,3-dioxygenase. Newly isolated bacterial strain, Agrobacterium sp. PH-08, grew well with and degraded DF via both angular and lateral dioxygenation as demonstrated by metabolites identified through ESI LC-MS/MS and GC-MS analyses. The other heterocyclic pollutants were also cometabolically degraded. Few reports have described the complete degradation of DF by a cometabolic lateral pathway. Our study demonstrates the novel results that the newly isolated strain utilized the DF as a sole carbon source and mineralized it via multiple dioxygenation. © 2013 The Society for Applied Microbiology.

Characterization of newly isolated lytic bacteriophages active against Acinetobacter baumannii.

Directory of Open Access Journals (Sweden)

Maia Merabishvili

Full Text Available Based on genotyping and host range, two newly isolated lytic bacteriophages, myovirus vB_AbaM_Acibel004 and podovirus vB_AbaP_Acibel007, active against Acinetobacter baumannii clinical strains, were selected from a new phage library for further characterization. The complete genomes of the two phages were analyzed. Both phages are characterized by broad host range and essential features of potential therapeutic phages, such as short latent period (27 and 21 min, respectively, high burst size (125 and 145, respectively, stability of activity in liquid culture and low frequency of occurrence of phage-resistant mutant bacterial cells. Genomic analysis showed that while Acibel004 represents a novel bacteriophage with resemblance to some unclassified Pseudomonas aeruginosa phages, Acibel007 belongs to the well-characterized genus of the Phikmvlikevirus. The newly isolated phages can serve as potential candidates for phage cocktails to control A. baumannii infections.

2010-01-01

The purpose of this article is to carry out, a discussion on the subject of bioethics and cadavers based upon a critic review of literature. A review of literature, was made with a survey of articles between 1977 and 2007 in the sites 'Biblioteca Virtual de Saúde', PubMed and SciElo, utilizing the keywords: newly deceased patients, newly dead patients, simulators,. This was complemented by a critical evaluation of books published in the area of ethics and bioethics. The possibility to develop learning without orientation by a supervisor is doubtful.. The utilization of newly dead for learning invasive procedures is very frequent and seldom admitted. These procedures, are usually, carried out secretly, without the knowledge and consent of the family. The ethical aspects of these practices are not discussed in the practical medical education. It essential that the ethics of use of recent deceased become a necessary content of graduate education. Performance of these procedures by students should always be authorized by family members. The simulators meet the requirements of training. Discussions about the ethical and bioethical aspects cannot be separated from practical considerations during the students learning time.

Generation of neutron scattering cross sections for silicon dioxide

International Nuclear Information System (INIS)

Ramos, R; Marquez Damian, J.I; Granada, J.R.; Cantargi, F

2009-01-01

A set of neutron scattering cross sections for silicon and oxygen bound in silicon dioxide were generated and validated. The cross sections were generated in the ACE format for MCNP using the nuclear data processing system NJOY, and the validation was done with published experimental data. This cross section library was applied to the calculation of five critical configurations published in the benchmark Critical Experiments with Heterogeneous Compositions of Highly Enriched Uranium, Silicon Dioxide and Polyethylene. The original calculations did not use the thermal scattering libraries generated in this work and presented significant differences with the experimental results. For this reason, the newly generated library was added to the input and the multiplication factor for each configuration was recomputed. The utilization of the thermal scattering libraries did not result in an improvement of the computational results. Based on this we conclude that integral experiments to validate this type of thermal cross sections need to be designed with a higher influence of thermal scattering in the measured result, and the experiments have to be performed under more controlled conditions.

Seizures beget seizures in temporal lobe epilepsies: the boomerang effects of newly formed aberrant kainatergic synapses.

Science.gov (United States)

Ben-Ari, Yehezkel; Crepel, Valérie; Represa, Alfonso

2008-01-01

Do temporal lobe epilepsy (TLE) seizures in adults promote further seizures? Clinical and experimental data suggest that new synapses are formed after an initial episode of status epilepticus, however their contribution to the transformation of a naive network to an epileptogenic one has been debated. Recent experimental data show that newly formed aberrant excitatory synapses on the granule cells of the fascia dentate operate by means of kainate receptor-operated signals that are not present on naive granule cells. Therefore, genuine epileptic networks rely on signaling cascades that differentiate them from naive networks. Recurrent limbic seizures generated by the activation of kainate receptors and synapses in naive animals lead to the formation of novel synapses that facilitate the emergence of further seizures. This negative, vicious cycle illustrates the central role of reactive plasticity in neurological disorders.

Optimized Generator Designs for the DTU 10-MW Offshore Wind Turbine using GeneratorSE

Energy Technology Data Exchange (ETDEWEB)

Sethuraman, Latha; Maness, Michael; Dykes, Katherine

2017-01-09

Compared to land-based applications, offshore wind imposes challenges for the development of next generation wind turbine generator technology. Direct-drive generators are believed to offer high availability, efficiency, and reduced operation and maintenance requirements; however, previous research suggests difficulties in scaling to several megawatts or more in size. The resulting designs are excessively large and/or massive, which are major impediments to transportation logistics, especially for offshore applications. At the same time, geared wind turbines continue to sustain offshore market growth through relatively cheaper and lightweight generators. However, reliability issues associated with mechanical components in a geared system create significant operation and maintenance costs, and these costs make up a large portion of overall system costs offshore. Thus, direct-drive turbines are likely to outnumber their gear-driven counterparts for this market, and there is a need to review the costs or opportunities of building machines with different types of generators and examining their competitiveness at the sizes necessary for the next generation of offshore wind turbines. In this paper, we use GeneratorSE, the National Renewable Energy Laboratory's newly developed systems engineering generator sizing tool to estimate mass, efficiency, and the costs of different generator technologies satisfying the electromagnetic, structural, and basic thermal design requirements for application in a very large-scale offshore wind turbine such as the Technical University of Denmark's (DTU) 10-MW reference wind turbine. For the DTU reference wind turbine, we use the previously mentioned criteria to optimize a direct-drive, radial flux, permanent-magnet synchronous generator; a direct-drive electrically excited synchronous generator; a medium-speed permanent-magnet generator; and a high-speed, doubly-fed induction generator.

The scope of the paper is the presentation of a new method of generating numbers from a given distribution. The method uses the inverse cumulative distribution function and a method of flattening of probabilistic distributions. On the grounds of these methods, a new construction of chaotic maps was derived, which generates values from a given distribution. The analysis of the new method was conducted on the example of a newly constructed chaotic recurrences, based on the Box-Muller transformation and the quantile function of the exponential distribution. The obtained results certify that the proposed method may be successively applicable for the construction of generators of pseudo-random numbers.

2016-03-01

The first year turnover rate for newly licensed registered nurses is roughly 30% and increases to about 57% in the second year (Twibell et al., 2012). An effective preceptorship has been shown to better facilitate the first year transition (Hodges et al., 2008) and increase retention rates (Pine and Tart, 2007). The purpose of this study was to examine the relationships between newly licensed registered nurses' perceived preceptor role effectiveness, psychological empowerment and professional autonomy. A prospective, cross-sectional, descriptive research design was used. Sixty-nine newly licensed registered nurses were recruited and surveyed. Newly licensed registered nurses were found to have moderately high levels of perceived preceptor role effectiveness, psychological empowerment, and professional autonomy. Preceptor role effectiveness had significant, moderately, positive relationships with professional autonomy and psychological empowerment. There was also a significant relationship found between professional autonomy and psychological empowerment. Results show that preceptor role effectiveness is linked to increased professional autonomy and psychological empowerment. Therefore, effective preceptorships are necessary in easing the newly licensed registered nurse's transition to practice. Strategies to ensure effective preceptorships and enhance the NRLN's transition to practice are proposed. Copyright © 2016 Elsevier Ltd. All rights reserved.

Unique biodegradable property of magnesium has spawned countless studies to develop ideal biodegradable orthopedic implant materials in the last decade. However, due to the rapid pH change and extensive amount of hydrogen gas generated during biocorrosion, it is extremely difficult to determine the accurate cytotoxicity of newly developed magnesium alloys using the existing methods. Herein, we report a new method to accurately determine the cytotoxicity of magnesium alloys with varying corrosion rate while taking in-vivo condition into the consideration. For conventional method, extract quantities of each metal ion were determined using ICP-MS and the result showed that the cytotoxicity due to pH change caused by corrosion affected the cell viability rather than the intrinsic cytotoxicity of magnesium alloy. In physiological environment, pH is regulated and adjusted within normal pH (˜7.4) range by homeostasis. Two new methods using pH buffered extracts were proposed and performed to show that environmental buffering effect of pH, dilution of the extract, and the regulation of eluate surface area must be taken into consideration for accurate cytotoxicity measurement of biodegradable magnesium alloys.

To investigate the influence of parental sociodemographic, communication, and psychological factors on sperm collection attempts among at-risk adolescent males newly diagnosed with cancer. Prospective, single group, observational study design. Pediatric oncology centers. Parents (N = 144) of 122 newly diagnosed adolescent males at increased risk for infertility secondary to cancer therapy. Survey-based assessment of parent factors associated with adolescent collection attempts. Attempt of manual collection of sperm. Parental recommendation to bank sperm (odds ratio [OR] 3.72; 95% confidence interval [CI] 1.18-11.76) and perceived self-efficacy to facilitate banking (OR 1.20; 95% CI 1.02-1.41) were associated with an increased likelihood of making a collection attempt. Parental recommendation to bank is a critical influence for sperm banking among adolescent males newly diagnosed with cancer. These findings highlight the importance of effective communication between parents, patients, and health-care teams when discussing preservation options. Parent perceptions of their ability to facilitate sperm banking at the time of diagnosis should also be targeted in future interventions. NCT01152268. Copyright © 2017. Published by Elsevier Inc.

Dynamical generation of a composite quark-lepton symmetry

International Nuclear Information System (INIS)

Yasue, Masaki.

1981-05-01

We demonstrate the possibility that a basic [SU(2)]sup(N) symmetry of N subconstituents, which describes particle and antiparticle transitions, generates at most an ''effective'' SO(2N) symmetry and at least an ''effective'' SU(N) x U(1) symmetry of composite quarks and leptons whose states are specified by the N different kinds of subconstituents. The generators of the ''effective'' symmetry, are identified by the correct algebraic properties specific to SO(2N) of composite operators constructed from the [SU(2)]sup(N)-operators acting on the composite quark-lepton states. The composite quarks and leptons are found to respect SO(4) x SO(6) or SU(2)sub(L) x U(1)sub(R) x SU(3)sub(c) x U(1)sub(B-L) according to a new selection rule, which are generated by the bilinear products of the raising and lowering operators of [SU(2)] 5 . This construction of the SO(4) x SO(6) generators allows us to uniquely define the five quantum numbers of that symmetry even at the subconstituent level. The full SO(10) generators can be also constructed; however, one needs a newly arranged [SU(2)] 5 symmetry only defined at the composite level, the generators of which turn out to be at most N body operators of the original [SU(2)] 5 .

Williams, Brent A; Evans, Michael A; Honushefsky, Ashley M; Berger, Peter B

2017-10-12

Though warfarin has historically been the primary oral anticoagulant for stroke prevention in newly diagnosed atrial fibrillation (AF), several new direct oral anticoagulants may be preferred when anticoagulation control with warfarin is expected to be poor. This study developed a prediction model for time in therapeutic range (TTR) among newly diagnosed AF patients on newly initiated warfarin as a tool to assist decision making between warfarin and direct oral anticoagulants. This electronic medical record-based, retrospective study included newly diagnosed, nonvalvular AF patients with no recent warfarin exposure receiving primary care services through a large healthcare system in rural Pennsylvania. TTR was estimated as the percentage of time international normalized ratio measurements were between 2.0 and 3.0 during the first year following warfarin initiation. Candidate predictors of TTR were chosen from data elements collected during usual clinical care. A TTR prediction model was developed and temporally validated and its predictive performance was compared with the SAMe-TT 2 R 2 score (sex, age, medical history, treatment, tobacco, race) using R 2 and c-statistics. A total of 7877 newly diagnosed AF patients met study inclusion criteria. Median (interquartile range) TTR within the first year of starting warfarin was 51% (32, 67). Of 85 candidate predictors evaluated, 15 were included in the final validated model with an R 2 of 15.4%. The proposed model showed better predictive performance than the SAMe-TT 2 R 2 score ( R 2 =3.0%). The proposed prediction model may assist decision making on the proper mode of oral anticoagulant among newly diagnosed AF patients. However, predicting TTR on warfarin remains challenging. © 2017 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley.

Assessing the comparative effectiveness of newly marketed medications: methodological challenges and implications for drug development.

Schneeweiss, S; Gagne, J J; Glynn, R J; Ruhl, M; Rassen, J A

2011-12-01

Comparative-effectiveness research (CER) aims to produce actionable evidence regarding the effectiveness and safety of medical products and interventions as they are used outside of controlled research settings. Although CER evidence regarding medications is particularly needed shortly after market approval, key methodological challenges include (i) potential bias due to channeling of patients to the newly marketed medication because of various patient-, physician-, and system-related factors; (ii) rapid changes in the characteristics of the user population during the early phase of marketing; and (iii) lack of timely data and the often small number of users in the first few months of marketing. We propose a mix of approaches to generate comparative-effectiveness data in the early marketing period, including sequential cohort monitoring with secondary health-care data and propensity score (PS) balancing, as well as extended follow-up of phase III and phase IV trials, indirect comparisons of placebo-controlled trials, and modeling and simulation of virtual trials.

Optimized Generator Designs for the DTU 10-MW Offshore Wind Turbine using GeneratorSE: Preprint

Energy Technology Data Exchange (ETDEWEB)

Sethuraman, Latha; Maness, Michael; Dykes, Katherine

2017-01-01

Compared to land-based applications, offshore wind imposes challenges for the development of next generation wind turbine generator technology. Direct-drive generators are believed to offer high availability, efficiency, and reduced operation and maintenance requirements; however, previous research suggests difficulties in scaling to several megawatts or more in size. The resulting designs are excessively large and/or massive, which are major impediments to transportation logistics, especially for offshore applications. At the same time, geared wind turbines continue to sustain offshore market growth through relatively cheaper and lightweight generators. However, reliability issues associated with mechanical components in a geared system create significant operation and maintenance costs, and these costs make up a large portion of overall system costs offshore. Thus, direct-drive turbines are likely to outnumber their gear-driven counterparts for this market, and there is a need to review the costs or opportunities of building machines with different types of generators and examining their competitiveness at the sizes necessary for the next generation of offshore wind turbines. In this paper, we use GeneratorSE, the National Renewable Energy Laboratory's newly developed systems engineering generator sizing tool to estimate mass, efficiency, and the costs of different generator technologies satisfying the electromagnetic, structural, and basic thermal design requirements for application in a very large-scale offshore wind turbine such as the Technical University of Denmark's (DTU) 10-MW reference wind turbine.

Full Text Available Background Diabetes mellitus type 1 is one of the most prevalent endocrine diseases in pediatrics. Diabetic ketoacidosis is considered as one of the most threatening clinical pictures of DM1, especially if occurred as the first presentation of DM1 in children. Objectives The current study aimed to identify factors which may play a role in DKA onset in children. Methods This case-control study included all patients under 18 years old who referred to department of pediatrics endocrinology at Mashhad University Hospital (Imam Reza from January 2013 to December 2015 as newly diagnosed patients with DM1. Patients who fulfilled DKA criteria at diagnosis were considered as DKA group and those who referred with other presentations were considered as control group (non-DKA group. Data were analyzed by SPSS software ver. 16. Results During the study period, 97 (39.2% male newly diagnosed patients were included as DKA group. Accordingly 97 gender- and age-matched patients were added as non-DKA group. The most prevalent symptoms in both groups were polyuria (91.88% and polydipsia (88.66%. Fever and cold symptoms were significantly higher in the DKA group (P < 0.001 and P =0.005, respectively. Hemoglobin A1c level was significantly higher in the DKA group (P = 0.001, while body mass index was significantly lower in the DKA group (P = 0.045. Fever and father’s education level were the most important risk and protective factors in the DKA onset in newly diagnosed patients with DM1 (adjusted OR = 10.1, 95% CI = 2.9-35.3; P < 0.001 and adjusted OR = 0.5, 95% CI = 0.3 - 0.9 and P = 0.019, respectively. Conclusions In conclusion, a recent febrile illness was found as the strongest risk factor and father’s education level as the main protective factor in the DKA to diagnose children with DM1. The study findings suggested that DKA is a severe form of DM1 instead of a neglected or misdiagnosed disease.

Ethical climate and nurse competence - newly graduated nurses' perceptions.

Numminen, Olivia; Leino-Kilpi, Helena; Isoaho, Hannu; Meretoja, Riitta

2015-12-01

Nursing practice takes place in a social framework, in which environmental elements and interpersonal relations interact. Ethical climate of the work unit is an important element affecting nurses' professional and ethical practice. Nevertheless, whatever the environmental circumstances, nurses are expected to be professionally competent providing high-quality care ethically and clinically. This study examined newly graduated nurses' perception of the ethical climate of their work environment and its association with their self-assessed professional competence, turnover intentions and job satisfaction. Descriptive, cross-sectional, correlational research design was applied. Participants consisted of 318 newly graduated nurses. Data were collected electronically and analysed statistically. Ethical approval and permissions to use instruments and conduct the study were obtained according to required procedures. Data were rendered anonymous to protect participant confidentiality. Completing the questionnaire was interpreted as consent to participate. Nurses' overall perception of the ethical climate was positive. More positive perceptions related to peers, patients and physicians, and less positive to hospitals and managers. Strong associations were found between perceived ethical climate and self-assessed competence, turnover intentions in terms of changing job, and job satisfaction in terms of quality of care. Nurses at a higher competence level with positive views of job satisfaction and low turnover intentions perceived the climate significantly more positively. Nursing management responsible for and having the power to implement changes should understand their contribution in ethical leadership, as well as the multidimensional nature of nurses' work environment and the interaction between work-related factors in planning developmental measures. Future research should focus on issues in nurse managers' ethical leadership in creating ethical work environments. There

Ulbricht, Christine M; Rothschild, Anthony J; Hunnicutt, Jacob N; Lapane, Kate L

2017-11-01

The objective of this study is to describe the prevalence of depression and cognitive impairment among newly admitted nursing home residents in the USA and to describe the treatment of depression by level of cognitive impairment. We identified 1,088,619 newly admitted older residents between 2011 and 2013 with an active diagnosis of depression documented on the Minimum Data Set 3.0. The prevalence of receiving psychiatric treatment was estimated by cognitive impairment status and depression symptoms. Binary logistic regression using generalized estimating equations provided adjusted odds ratios and 95% confidence intervals for the association between level of cognitive impairment and receipt of psychiatric treatment, adjusted for clustering of residents within nursing homes and resident characteristics. Twenty-six percent of newly admitted residents had depression; 47% of these residents also had cognitive impairment. Of those who had staff assessments of depression, anhedonia, impaired concentration, psychomotor disturbances, and irritability were more commonly experienced by residents with cognitive impairment than residents without cognitive impairment. Forty-eight percent of all residents with depression did not receive any psychiatric treatment. Approximately one-fifth of residents received a combination of treatment. Residents with severe cognitive impairment were less likely than those with intact cognition to receive psychiatric treatment (adjusted odds ratio = 0.95; 95% confidence interval: 0.93-0.98). Many newly admitted residents with an active diagnosis of depression are untreated, potentially missing an important window to improve symptoms. The extent of comorbid cognitive impairment and depression and lack of treatment suggest opportunities for improved quality of care in this increasingly important healthcare setting.

Wangensteen, Sigrid; Johansson, Inger S; Björkström, Monica E; Nordström, Gun

2010-10-01

The aim of the study was to describe critical thinking dispositions among newly graduated nurses in Norway, and to study whether background data had any impact on critical thinking dispositions. Competence in critical thinking is one of the expectations of nursing education. Critical thinkers are described as well-informed, inquisitive, open-minded and orderly in complex matters. Critical thinking competence has thus been designated as an outcome for judging the quality of nursing education programmes and for the development of clinical judgement. The ability to think critically is also described as reducing the research-practice gap and fostering evidence-based nursing. A cross-sectional descriptive study was performed. The data were collected between October 2006 and April 2007 using the California Critical Thinking Disposition Inventory. The response rate was 33% (n = 618). Pearson's chi-square tests were used to analyse the data. Nearly 80% of the respondents reported a positive disposition towards critical thinking. The highest mean score was on the Inquisitiveness subscale and the lowest on the Truth-seeking subscale. A statistically significant higher proportion of nurses with high critical thinking scores were found among those older than 30 years, those with university education prior to nursing education, and those working in community health care. Nurse leaders and nurse teachers should encourage and nurture critical thinking among newly graduated nurses and nursing students. The low Truth-seeking scores found may be a result of traditional teaching strategies in nursing education and might indicate a need for more student-active learning models. © 2010 The Authors.

To prospectively identify different coping strategies among newly diagnosed amyotrophic lateral sclerosis patients and whether they change over time and to determine whether physical function, psychological well-being, age and gender correlated with the use of different coping strategies. Amyotrophic lateral sclerosis is a fatal disease with impact on both physical function and psychological well-being. Different coping strategies are used to manage symptoms and disease progression, but knowledge about coping in newly diagnosed amyotrophic lateral sclerosis patients is scarce. This was a prospective study with a longitudinal and descriptive design. A total of 33 patients were included and evaluation was made at two time points, one to three months and six months after diagnosis. Patients were asked to complete the Motor Neuron Disease Coping Scale and the Hospital Anxiety and Depression Scale. Physical function was estimated using the revised Amyotrophic Lateral Sclerosis Functional Rating Scale. The most commonly used strategies were support and independence. Avoidance/venting and information seeking were seldom used at both time points. The use of information seeking decreased between the two time points. Men did not differ from women, but patients ≤64 years used positive action more often than older patients. Amyotrophic Lateral Sclerosis Functional Rating Scale was positively correlated with positive action at time point 1, but not at time point 2. Patients' psychological well-being was correlated with the use of different coping strategies. Support and independence were the most used coping strategies, and the use of different strategies changed over time. Psychological well-being was correlated with different coping strategies in newly diagnosed amyotrophic lateral sclerosis patients. The knowledge about coping strategies in early stage of the disease may help the nurses to improve and develop the care and support for these patients. © 2014 John Wiley

The response of a recently acquired Canberra(trademark) Alpha Analyst 'Blue' system (Chamber Number's 173-208) used by the Hazards Control, Radiation Safety Section, WBC/Spectroscopy Team has been studied with respect to an existing Canberra system. The existing Canberra system consists of thirty Alpha Analyst dual chambers Model XXXX comprising a total of sixty detectors (Chambers Number's 101-124 and 137-172). The existing chambers were previously compared to an older system consisting of thirty-six Model 7401 alpha spectrometry chambers (Chamber Number's 1-36) Chambers 101-124 and 137-172 are DOELAP accredited. The older system was previously DOELAP accredited for the routine Alpha Spectroscopy program used in LLNL's in vitro bioassay program. The newly acquired Alpha Analyst system operates on a network with software that controls and performs analysis of the current Alpha Analyst system (Chamber Number's 101-124 and 137-172). This exact same software is used for the current system and the newly acquired system and is DOELAP accredited. This document compares results from the existing Alpha System with the newer Alpha Analyst system

Scandinavian exceptionalism? Civic integration and labour market activation for newly arrived immigrants.

Science.gov (United States)

Breidahl, Karen N

2017-01-01

Since the late 1990s, a wide range of so-called new civic integration policies aimed at civilizing or disciplining newcomers have been introduced. Consequently, migration scholars have discussed whether a converging restrictive 'civic turn' has taken place in Western Europe or whether national models have been resilient: Based on an in-depth historical and comparative analysis of labour market activation policies targeting newly arrived immigrants in Sweden, Norway, and Denmark since the early 1990s, the article contributes to the overall question: To what extent do the institutional pathways of the Scandinavian welfare states prevail when confronted with newcomers? Activation policies targeting newly arrived immigrants exemplifies how the ambition of states to promote functional, individual autonomy is also an important, ongoing process in diverse policy areas of the welfare state and not restricted to early integration instruments. While the Scandinavian welfare states differ on a number of counts with respect to immigration control, national integration philosophies and citizenship policies, the article outlines how activation policies aimed at newly arrived immigrants share several features. One of the key factors in this turn involves path dependency from, among others, a lengthy tradition for strong state involvement and norms about employment. Another factor in this turn involves transnational policy learning. On some points, national versions of these policies are also found due to country-specific citizenship traditions, integration philosophies and party political constellations.

Newly introduced sample preparation techniques: towards miniaturization.

Science.gov (United States)

Costa, Rosaria

2014-01-01

Sampling and sample preparation are of crucial importance in an analytical procedure, representing quite often a source of errors. The technique chosen for the isolation of analytes greatly affects the success of a chemical determination. On the other hand, growing concerns about environmental and human safety, along with the introduction of international regulations for quality control, have moved the interest of scientists towards specific needs. Newly introduced sample preparation techniques are challenged to meet new criteria: (i) miniaturization, (ii) higher sensitivity and selectivity, and (iii) automation. In this survey, the most recent techniques introduced in the field of sample preparation will be described and discussed, along with many examples of applications.

Depth-variable settlement patterns and predation influence on newly settled reef fishes (Haemulon spp., Haemulidae.

Directory of Open Access Journals (Sweden)

Lance K B Jordan

Full Text Available During early demersal ontogeny, many marine fishes display complex habitat-use patterns. Grunts of the speciose genus Haemulon are among the most abundant fishes on western North Atlantic coral reefs, with most species settling to shallow habitats (≤12 m. To gain understanding into cross-shelf distributional patterns exhibited by newly settled stages of grunts (<2 cm total length, we examined: 1 depth-specific distributions of congeners at settlement among sites at 8 m, 12 m, and 21 m, and 2 depth-variable predation pressure on newly settled individuals (species pooled. Of the six species identified from collections of newly settled specimens (n = 2125, Haemulon aurolineatum (tomtate, H. flavolineatum (French grunt, and H. striatum (striped grunt comprised 98% of the total abundance; with the first two species present at all sites. Prevalence of H. aurolineatum and H. flavolineatum decreased substantially from the 8-m site to the two deeper sites. In contrast, H. striatum was absent from the 8-m site and exhibited its highest frequency at the 21-m site. Comparison of newly settled grunt delta density for all species on caged (predator exclusion and control artificial reefs at the shallowest site (8-m revealed no difference, while the 12-m and 21-m sites exhibited significantly greater delta densities on the caged treatment. This result, along with significantly higher abundances of co-occurring piscivorous fishes at the deeper sites, indicated lower predation pressure at the 8-m site. This study suggests habitat-use patterns of newly settled stages of some coral reef fishes that undergo ontogenetic shifts are a function of depth-variable predation pressure while, for at least one deeper-water species, proximity to adult habitat appears to be an important factor affecting settlement distribution.

2016-02-03

New adjuvants such as the AS- or the MF59-adjuvants improve vaccine efficacy and facilitate dose-sparing. Their use in influenza and malaria vaccines has resulted in a large body of evidence on their clinical safety in children. We carried out a systematic search for safety data from published clinical trials on newly adjuvanted vaccines in children ≤10 years of age. Serious adverse events (SAEs), solicited AEs, unsolicited AEs and AEs of special interest were evaluated for four new adjuvants: the immuno-stimulants containing adjuvant systems AS01 and AS02, and the squalene containing oil-in-water emulsions AS03 and MF59. Relative risks (RR) were calculated, comparing children receiving newly adjuvanted vaccines to children receiving other vaccines with a variety of antigens, both adjuvanted and unadjuvanted. Twenty-nine trials were included in the meta-analysis, encompassing 25,056 children who received at least one dose of the newly adjuvanted vaccines. SAEs did not occur more frequently in adjuvanted groups (RR 0.85, 95%CI 0.75-0.96). Our meta-analyses showed higher reactogenicity following administration of newly adjuvanted vaccines, however, no consistent pattern of solicited AEs was observed across adjuvant systems. Pain was the most prevalent AE, but often mild and of short duration. No increased risks were found for unsolicited AEs, febrile convulsions, potential immune mediated diseases and new onset of chronic diseases. Our meta-analysis did not show any safety concerns in clinical trials of the newly adjuvanted vaccines in children ≤10 years of age. An unexplained increase of meningitis in one Phase III AS01-adjuvanted malaria trial and the link between narcolepsy and the AS03-adjuvanted pandemic vaccine illustrate that continued safety monitoring is warranted.

Ivarsson, Bodil; Nilsson, Gunilla

2009-07-01

The aim was to describe, from the newly registered nurses' perspective, specific events when using their pedagogical knowledge in their everyday clinical practice. The design was qualitative and the critical incident technique was used. Data was collected via interviews with ten newly registered nurses who graduated from the same University program 10 months earlier and are now employed at a university hospital. Two categories emerged in the analyses. The first category was "Pedagogical methods in theory" with the sub-categories Theory and the application of the course in practice, Knowledge of pedagogy and Information as a professional competence. The second category was "Pedagogical methods in everyday clinical practice" with sub-categories Factual knowledge versus pedagogical knowledge, Information and relatives, Difficulties when giving information, Understanding information received, Pedagogical tools, Collaboration in teams in pedagogical situations, and Time and giving information. By identifying specific events regarding pedagogical methods the findings can be useful for everyone from teachers and health-care managers to nurse students and newly registered nurses, to improve teaching methods in nurse education.

Assessment of the Quality of Newly Formed Bone around Titanium Alloy Implants by Using X-Ray Photoelectron Spectroscopy

Directory of Open Access Journals (Sweden)

Hiroshi Nakada

2012-01-01

Full Text Available The aim of this study was to evaluate differences in bones quality between newly formed bone and cortical bone formed around titanium alloy implants by using X-ray photoelectron spectroscopy. As a result of narrow scan measurement at 4 weeks, the newly formed bone of C1s, P2p, O1s, and Ca2p were observed at a different peak range and strength compared with a cortical bone. At 8 weeks, the peak range and strength of newly formed bone were similar to those of cortical bone at C1s, P2p, and Ca2p, but not O1s. The results from this analysis indicate that the peaks and quantities of each element of newly formed bone were similar to those of cortical bone at 8 weeks, suggestive of a strong physicochemical resemblance.

It is unclear whether a woman's age influences her risk of cervical intraepithelial neoplasia grade 3 or worse (CIN3+) upon detection of HPV. A large change in risk as women age would influence vaccination and screening policies. Among 972,029 women age 30-64 undergoing screening with Pap and HPV testing (Hybrid Capture 2, Qiagen, Germantown, MD) at Kaiser Permanente Northern California (KPNC), we calculated age-specific 5-year CIN3+ risks among women with HPV infections detected at enrollment, and among women with "newly detected" HPV infections at their second screening visit. Women (57,899, 6.0%) had an enrollment HPV infection. Among the women testing HPV negative at enrollment with a second screening visit, 16,724 (3.3%) had a newly detected HPV infection at their second visit. Both enrollment and newly detected HPV rates declined with age (p < 0.001). Women with enrollment versus newly detected HPV infection had higher 5-year CIN3+ risks: 8.5% versus 3.9%, (p < 0.0001). Risks did not increase with age but declined slightly from 30-34 years to 60-64 years: 9.4% versus 7.4% (p = 0.017) for enrollment HPV and 5.1% versus 3.5% (p = 0.014) for newly detected HPV. Among women age 30-64 in an established screening program, women with newly detected HPV infections were at lower risk than women with enrollment infections, suggesting reduced benefit vaccinating women at older ages. Although the rates of HPV infection declined dramatically with age, the subsequent CIN3+ risks associated with HPV infection declined only slightly. The CIN3+ risks among older women are sufficiently elevated to warrant continued screening through age 65. © 2014 UICC.

We examined the relationship between the O(6)-methylguanine-methyltransferase (MGMT) methylation status and clinical outcomes in newly diagnosed glioblastoma multiforme (GBM) patients who were treated with Gliadel wafers (Eisai, Tokyo, Japan). MGMT promoter methylation has been associated with increased survival among patients with GBM who are treated with various alkylating agents. MGMT promoter methylation, in DNA from 122 of 160 newly diagnosed GBM patients treated with Gliadel, was determined by a quantitative methylation-specific polymerase chain reaction, and was correlated with overall survival (OS) and recurrence-free survival (RFS). The MGMT promoter was methylated in 40 (32.7%) of 122 patients. The median OS was 13.5 months (95% confidence interval [CI] 11.0-14.5) and RFS was 9.4 months (95% CI 7.8-10.2). After adjusting for age, Karnofsky performance score, extent of resection, temozolomide (TMZ) and radiation therapy (RT), the newly diagnosed GBM patients with MGMT methylation had a 15% reduced mortality risk, compared to patients with unmethylated MGMT (hazard ratio 0.85; 95% CI 0.56-1.31; p=0.46). The patients aged over 70 years with MGMT methylation had a significantly longer median OS of 13.5 months, compared to 7.6 months in patients with unmethylated MGMT (p=0.027). A significant difference was also found in older patients, with a median RFS of 13.1 versus 7.6 months for methylated and unmethylated MGMT groups, respectively (p=0.01). Methylation of the MGMT promoter in newly diagnosed GBM patients treated with Gliadel, RT and TMZ, was associated with significantly improved OS compared to the unmethylated population. In elderly patients, methylation of the MGMT promoter was associated with significantly better OS and RFS. Copyright © 2015 Elsevier Ltd. All rights reserved.

Semiconductor scaling is slowing down because of difficulties of device manufacturing below logic 7nm node generation. Various lithography candidates which include ArF immersion with resolution enhancement technology (like Inversed Lithography technology), Extreme Ultra Violet lithography and Nano Imprint lithography are being developed to address the situation. In such advanced lithography, shot counts of mask patterns are estimated to increase explosively in critical layers, and then it is hoped that multi beam mask writer (MBMW) is released to handle them within realistic write time. However, ArF immersion technology with multiple patterning will continue to be a mainstream lithography solution for most of the layers. Then, the shot counts in less critical layers are estimated to be stable because of the limitation of resolution in ArF immersion technology. Therefore, single beam mask writer (SBMW) can play an important role for mask production still, relative to MBMW. Also the demand of SBMW seems actually strong for the logic 7nm node. To realize this, we have developed a new SBMW, EBM-9500 for mask fabrication in this generation. A newly introduced electron beam source enables higher current density of 1200A/cm2. Heating effect correction function has also been newly introduced to satisfy the requirements for both pattern accuracy and throughput. In this paper, we will report the configuration and performance of EBM-9500.

Alterations found with computerized tomography in newly diagnosed type 2 diabetics

International Nuclear Information System (INIS)

Bruna, J.

1989-01-01

In 28 newly diagnosed type 2 diabetic patients (insulin-independent), computerized tomography (CT) was used to determine the density of the pancreas and the kidneys, densities of the liver, spleen and blood in the abdominal aorta, and to investigate pathological changes in the tissues mentioned above. The results were correlated with laboratory findings. The following changes were found: decreased density of the pancreas (29.4 H) and the liver (49.1 H) and increased density of the spleen (56.3 H) and blood in the abdominal aorta (43.7 H). The decreased density of the pancreas appears to be connected with disorders of lipoprotein metabolism. The decreased liver density was related to increased energy intake by food and to overweight evaluated by Broc's index. Other CT findings in the newly diagnosed type 2 diabetics (changes in the size of the pancreas, and kidneys, kidney cysts, nephrolithiasis, sclerotic plaques on aorta) were not significant.

A range of newly developed mobile generators to dynamically produce SI-traceable reference gas mixtures for reactive compounds at atmospheric concentrations

Science.gov (United States)

Leuenberger, Daiana; Pascale, Céline; Guillevic, Myriam; Ackermann, Andreas; Niederhauser, Bernhard

2017-04-01

Three new mobile facilities have been developed at METAS to dynamically generate SI-traceable reference gas mixtures for a variety of reactive compounds at atmospheric amount of substance fractions and at very low levels of uncertainty (Ux balance. The carrier gas is previously purified from the compounds of interest using commercially available purification cartridges. The permeation chambers of ReGaS2 and ReGaS3 have multiple individual cells allowing for the generation of mixtures containing up to 5 different components if required. ReGaS1 allows for the generation of one-component mixtures only. These primary mixtures are then diluted to the required amount of substance fractions using thermal mass flow controllers for full flexibility and adaptability of the generation process over the entire range of possible concentrations. In order to considerably reduce adsorption/desorption processes and thus stabilisation time, all electro-polished stainless steel parts of ReGaS1 and ReGaS2 in contact with the reference gas mixtures are passivated with SilcoNert2000® surface coating. These three state-of-the-art mobile reference gas generators are applicable under both, laboratory and field conditions. Moreover the dynamic generation method can be adapted and applied to a large variety of molecules (e.g. BTEX, CFCs, HCFCs, HFCs and other refrigerants) and is particularly suitable for reactive gas species and/or at concentration ranges which are unstable when stored in pressurised cylinders.

This study aimed to examine the treatment decision-making process for children hospitalized with newly diagnosed immune thrombocytopenia (ITP). Using focus groups, we studied children with ITP, parents of children with ITP, and health care professionals, inquiring about participants' experience with decision support and decision making in newly diagnosed ITP. Data were examined using thematic analysis. Themes that emerged from children were feelings of "anxiety, fear, and confusion"; the need to "understand information"; and "treatment choice," the experience of which was age dependent. For parents, "anxiety, fear, and confusion" was a dominant theme; "treatment choice" revealed that participants felt directed toward intravenous immune globulin (IVIG) for initial treatment. For health care professionals, "comfort level" highlighted factors contributing to professionals' comfort with offering options; "assumptions" were made about parental desire for participation in shared decision making (SDM) and parental acceptance of treatment options; "providing information" was informative regarding modes of facilitating SDM; and "treatment choice" revealed a discrepancy between current practice (directed toward IVIG) and the ideal of SDM. At our center, families of children with newly diagnosed ITP are not experiencing SDM. Our findings support the implementation of SDM to facilitate patient-centered care for the management of pediatric ITP.

Abnormalities in serum lipid and lipoprotein levels are recognized major modifiable cardiovascular disease and essential hypertension risk factors. The objective of this study was to examine the serum lipid patterns of newly diagnosed hypertensive patients attending a tertiary healthcare centre in South East Nigeria. Methods. Two hundred and fifty newly diagnosed adult hypertensive patients and an equal number of age- and sex-matched controls without hypertension were consecutively recruited from the Medical and General Outpatient Clinics of Nnamdi Azikiwe University Teaching Hospital, Nnewi. Result. 126 males and 124 females were in each of the two groups. Mean age was comparable in both groups. Hypertensives had significantly higher mean systolic blood pressure, diastolic blood pressure, body mass index, waist circumference, waist-hip ratio, and fasting blood sugar than the controls. The mean TC, TG, and LDL-C were significantly higher among the hypertensives. The mean HDL-C was comparable; P = 0.8. Among the hypertensive subjects, there was statistically significant positive correlation between BMI and TC; LDL-C and TG; WC and TG; FBS and TC; LDL-C and TG. HDL-C showed a statistically significant inverse correlation with WHR in hypertensives. Conclusion. This study showed that lipid abnormalities are highly prevalent among newly diagnosed hypertensives in South-East Nigeria.

Mammals, including human beings, have evolved a unique viviparous reproductive system and a highly developed central nervous system. How did these unique characteristics emerge in mammalian evolution, and what kinds of changes did occur in the mammalian genomes as evolution proceeded? A key conceptual term in approaching these issues is "mammalian-specific genomic functions", a concept covering both mammalian-specific epigenetics and genetics. Genomic imprinting and LTR retrotransposon-derived genes are reviewed as the representative, mammalian-specific genomic functions that are essential not only for the current mammalian developmental system, but also mammalian evolution itself. First, the essential roles of genomic imprinting in mammalian development, especially related to viviparous reproduction via placental function, as well as the emergence of genomic imprinting in mammalian evolution, are discussed. Second, we introduce the novel concept of "mammalian-specific traits generated by mammalian-specific genes from LTR retrotransposons", based on the finding that LTR retrotransposons served as a critical driving force in the mammalian evolution via generating mammalian-specific genes.

Full Text Available Nitrogen concentration was measured via 2.52 MeV nitrogen gamma ray from melamine, caffeine, urea, and disperse orange bulk samples using a newly designed D-D portable neutron generator-based prompt gamma ray setup. Inspite of low flux of thermal neutrons produced by D-D reaction-based portable neutron generator and interference of 2.52 MeV gamma rays from nitrogen in bulk samples with 2.50 MeV gamma ray from bismuth in BGO detector material, an excellent agreement between the experimental and calculated yields of nitrogen gamma rays indicates satisfactory performance of the setup for detection of nitrogen in bulk samples.

The energy-saving generation dispatch (ESGD) policy released by Chinese Government in 2007 is a new code for optimally dispatching electric power generation portfolio in the country with the dual objectives of improving energy efficiency and reducing environmental pollution. The ESGD is substantially different from the competitive market in the developed economies, the traditional economic dispatching or the rational dispatching principle implemented in China prior to the new policy. This paper develops a hybrid method that integrates the extended priority list (EPL), the equal incremental principle (EIP) and a heuristic method to optimize daily generation schedules under ESGD. The EPL is presented to search desirable units set that satisfies the complicated duration period requirements based on thermal unit generation priority list. The EIP is developed to allocate load among the committed units within the combined set. A heuristic method is proposed to deal with inequality constraints, which usually result in difficulty for power allocation, and used to improve these results. The algorithm has been embedded into a newly developed decision support system that is currently being used by operators of the Guizhou Province Power Grid to make day-ahead quarter-hourly generation schedules. - Highlights: • Electric power industry is one of key and important fields for energy conservation and emission reduction in China. • The energy-saving generation dispatch policy was released by Chinese government in 2007. • A Hybrid algorithm for energy-saving generation dispatch scheduling of thermal power system is presented. • The algorithm has been embedded into a newly developed decision support system

To investigate transition in newly qualified nurses through an exploration of their stressors and stress experiences during their first 12 months postqualifying. Globally, thousands of new nurses qualify annually. They are crucial for the profession and healthcare service delivery. Work-related stress has multiple serious consequences, yet there is a lack of robust, empirical evidence that directly analyses newly qualified nurses and the stress they feel and experience in the workplace. Understanding what causes newly qualified nurses' stress is vital to retaining and nurturing this vital component of the workforce. Longitudinal, explanatory sequential mixed methods, cohort study. At the point of qualification (n = 288), 6 months postqualifying (n = 107) and 12 months postqualifying (n = 86), newly qualified nurses completed the Nursing Stress Scale, with 14 completing a one-to-one interview at 12 months postqualifying. Data were collected from 2010 - 2012. Inferential statistics, "thematic analysis" and "side-by-side comparisons in a discussion" were used for analysis. Workload was consistently the highest reported stressor with inadequate staffing and managing multiple role demands given as explanations. Incivility within the workplace was a noted stressor. Conversely, being part of "a good team" provided a civil, supportive, facilitative work environment. Entering nurse education with previous healthcare experience had a mediating effect on the reported frequency of stressors. Newly qualified nurses encounter multiple work-related stressors over their first 12 months postqualifying, which are intrinsically entwined with their transition. Employing organizations need to be more proactive in managing their workload and addressing workplace incivility. © 2017 John Wiley & Sons Ltd.

OSA is bound up with heightened cardiovascular mortality. Aim: Тo study frequency, features, and structure of sleep disordered breathing in patients with newly diagnosed acromegaly and to elucidate the factors influencing their development. Materials and methods: 38 patients (10 men, 28 women, median age 53 (28-76 years, median body mass index (BMI 29 (19.9-44.3 kg/m² with newly diagnosed acromegaly were recruited into the study. All subjects underwent full polysomnography (Embla N7000, Natus, USA and Remlogica software (USA. Results: Sleep disordered breathing was found in 28 (73.7% patients. OSA was revealed in all cases, in 11 (39.3% subjects it was mixed. In 10 (35.7% patients OSA was mild, in 8 (28.6% moderate, and in 10 (35.7% severe. BMI (р<0.01, disease duration (р=0.003, and insulin-like growth factor-1 (IGF-1 level (р=0.04 were different in patients without OSA and patients with moderate-to-severe OSA. No difference was found in sex (р=0.4, age (р=0.064, and growth hormone level (р=0.6. Frequency of arterial hypertension, diabetes mellitus, and other glucose metabolism impairments was the same in subjects without OSA and with severe-to-moderate OSA. Conclusion: All patients with newly diagnosed acromegaly should undergo polysomnography. BMI, disease duration, and IGF-1 level are significant risk factors for OSA development. Correlation OSA with arterial hypertension and glucose metabolism impairments needs to be further investigated.

Full Text Available Background: Diabetic retinopathy is the commonest and usually the first observable vascular complication of diabetes mellitus. Along with hyperglycaemia, dyslipidaemia is a contributing factor for the occurrence of diabetic retinopathy. It is postulated that dyslipidaemia results in formation of hard exudate by increasing blood viscosity and altering the fibrinolytic system. A case control study was carried out in the department of Biochemistry, Bangabandhu Sheikh Mujib Medical University, Dhaka during the period of January 2006 to December 2007 to evaluate the serum lipid profile in newly diagnosed type 2 diabetic subjects with diabetic retinopathy. Materials and Methods: Total 85 newly diagnosed type 2 diabetic subjects were included in this study, 40 were cases having retinopathy and 45 were age and sex matched controls without retinopathy. Serum triglyceride (TG, total cholesterol (TC, low density lipoprotein cholesterol (LDL-C and high density lipoprotein cholesterol (HDL-C were compared between cases and controls. Unpaired t-test and chi-square test were done between groups as tests of significance. Results: All the parameters of lipid profile showed dyslipidaemic trend both in cases and controls. In the cases TG was significantly higher and HDL-C was significantly lower than that of controls (p < 0.05 whereas no significant difference was found between cases and controls with respect to serum TC and LDL-C. Conclusion: It can be concluded that high TG and low HDL-C are associated with diabetic retinopathy in newly diagnosed type 2 diabetes.

Abstract Objective To examine the remuneration model preferences of newly practising family physicians. Design Mixed-methods study comprising a cross-sectional, Web-based survey, as well as qualitative content analysis of answers to open-ended questions. Setting British Columbia. Participants University of British Columbia family practice residents who graduated between 2000 and 2009. Main outcome measures Preferred remuneration models of newly practising physicians. Results The survey response rate was 31% (133 of 430). Of respondents, 71% (93 of 132) preferred non–fee-for-service practice models and 86% (110 of 132) identified the payment model as very or somewhat important in their choice of future practice. Three principal themes were identified from content analysis of respondents’ open-ended comments: frustrations with fee-for-service billing, which encompassed issues related to aggravations with “the business side of things” and was seen as impeding “the freedom to focus on medicine”; quality of patient care, which embraced the importance of a payment model that supported “comprehensive patient care” and “quality rather than quantity”; and freedom to choose, which supported the plurality of practice preferences among providers who strived to provide quality care for patients, “whatever model you happen to be working in.” Conclusion Newly practising physicians in British Columbia preferred alternatives to fee-for-service payment models, which were perceived as contributing to fewer frustrations with billing systems, improved quality of work life, and better quality of patient care.

1988-01-01

The distribution and movement of cholesterol were studied in granulosa cells from the ovaries of estrogen-stimulated hypophysectomized immature rats cultured in serum-free medium. Plasma membrane cholesterol was distinguished from intracellular cholesterol with cholesterol oxidase, an enzyme that converts cell surface cholesterol to cholestenone, leaving intracellular cholesterol untouched. Using this approach we showed that 82% of unesterified cholesterol was associated with the plasma membrane in granulosa cells cultured for 48 h in serum-free medium in both the presence and absence of added androstenedione and FSH. FSH and androstenedione stimulated a marked increase in steroid hormone (progestin) production. The movement of newly synthesized cholesterol to the plasma membrane also was followed using cholesterol oxidase. Newly synthesized cholesterol reached the plasma membrane too rapidly to be measured in unstimulated cells (t1/2 less than 20 min); however, in cells stimulated by FSH and androstenedione, this rate was considerably slower (t1/2 approximately 2h). Therefore, cholesterol movement to the plasma membrane appears to be regulated by gonadotropins in these cells. We tested whether steroid biosynthesis used all cell cholesterol pools equally. To this end we administered [3H]acetate and [14C]acetate at different times and determined their relative specific contents in various steroids after defined intervals. The relative ages of the steroids (youngest to oldest) were: lanosterol, progestins, intracellular cholesterol, and plasma membrane cholesterol. This finding suggests that progestins use newly synthesized intracellular cholesterol in preference to preexisting intracellular or cell surface cholesterol

Purpose: To compare the survival of postresection recurrent vs. newly diagnosed non-small-cell lung cancer (NSCLC) patients treated with radiotherapy or chemoradiotherapy. Methods and Materials: The study population consisted of 661 consecutive patients with NSCLC registered in the radiation oncology databases at two medical centers in the United States between 1992 and 2004. Of the 661 patients, 54 had postresection recurrent NSCLC and 607 had newly diagnosed NSCLC. Kaplan-Meier and Cox regression models were used for the survival analyses. Results: The distribution of relevant clinical factors between these two groups was similar. The median survival time and 5-year overall survival rates were 19.8 months (95% confidence interval [CI], 13.9-25.7) and 14.8% (95% confidence interval, 5.4-24.2%) vs. 12.2 months (95% CI, 10.8-13.6) and 11.0% (95% CI, 8.5-13.5%) for recurrent vs. newly diagnosed patients, respectively (p = .037). For Stage I-III patients, no significant difference was observed in the 5-year overall survival (p = .297) or progression-free survival (p = .935) between recurrent and newly diagnosed patients. For the 46 patients with Stage I-III recurrent disease, multivariate analysis showed that chemotherapy was a significant prognostic factor for 5-year progression-free survival (hazard ratio, 0.45; 95% CI, 0.224-0.914; p = .027). Conclusion: Our institutional data have shown that patients with postresection recurrent NSCLC achieved survival comparable to that of newly diagnosed NSCLC patients when they were both treated with radiotherapy or chemoradiotherapy. These findings suggest that patients with postresection recurrent NSCLC should be treated as aggressively as those with newly diagnosed disease.

The use of antimicrobials in food animals is the major determinant for the propagation of resistant bacteria in the animal reservoir. However, other factors may also play a part, and in particular vertical spread between the generations has been suggested to be an important transmission pathway. The objective of this paper was to determine the resistance patterns of Escherichia coli isolated from newly-hatched chickens as well as to study the antibiotic pressure effect when amoxicillin was administered during their growing period. With this aim, meconium from 22 one-day-old Ross chickens was analysed. In addition, during their growth period, amoxicillin treatments at days 7, 21 and 35 were carried out. Results showed a high number of E. coli-resistant strains were isolated from the treated one-day-old chickens, and were the highest for β-lactams group, followed by quinolone and tetracyclines. After treatment with amoxicillin, the highest percentage of resistances were detected for this antibiotic compared to the others analysed, with significant differences in resistance percentages between control and treated broilers detected in relation to ampicillin, cephalothin, streptomycin, kanamycin, gentamicin, chloramphenicol and tetracycline. Differences in resistances to ciprofloxacin and nalidixic acid between control and treated animals were not observed and there was lack of resistance for amikacin and ceftriaxone. These results suggest the possibility of vertical transmission of resistant strains to newly-hatched chicks from parent flocks, and seem to indicate that the treatment with amoxicillin increased the resistance of E. coli to other antibiotics.

The primary objective of the current study was to examine the extent to which domain-specific time perspective predicts weight management behaviors (dietary behavior and physical activity) among those newly diagnosed with Type 2 diabetes. A secondary objective was to test potential mediators of the hypothesized effect (behavioral intention, self-efficacy and control beliefs). A total of 204 adults newly diagnosed (≤6 months) with Type 2 diabetes participated in the study, which included a baseline assessment of domain-general and domain-specific time perspective, as well as strength of intention to perform two weight-management behaviors (dietary choice and physical activity); both weight-management behaviors were assessed again at 6 month follow-up. Hierarchical multiple regression analyses revealed a prospective association between domain-specific time perspective and uptake of weight management behaviors. Individuals with newly diagnosed T2DM possessing a future-oriented time perspective reported making less frequent fatty food choices and greater increases in physical activity over the 6-month follow-up interval. These effects were selectively mediated by intention strength, and not competing social cognitive variables. For both behaviors, the total effects and meditational models were robust to adjustments for demographics, body composition and disease variables. A future-oriented time perspective is prospectively associated with superior uptake of weight management behaviors among those with newly diagnosed Type 2 diabetes. The facilitating effect of future-oriented thinking appears to occur via enhanced strength of intentions to perform weight management behaviors.

Full Text Available It is now well established that major risk factors for cardiovascular diseases (CVD impact upon endothelial function by decreasing nitric oxide (NO bioavailability. Asymmetric dimethylarginine (ADMA, an endogenous analog of l-arginine, is able to inhibit the activity of endothelial-NO synthase, promoting endothelial dysfunction. Type 2 diabetes (T2D is characterized by a reduced endothelium-dependent vasodilation and increased ADMA levels and ADMA is strongly associated with micro- and macrovascular diabetic complications. However, there are not a lot of data about the role of ADMA on endothelial function in newly diagnosed T2D patients without cardiovascular (CV complications. For this aim, we have enrolled forty-five newly diagnosed T2D patients, evaluated by a oral glucose tolerance test, and thirty normal subjects. Endothelium-dependent and -independent vasodilatation was investigated by intra-arterial infusion of increasing doses of acetylcholine (ACh and sodium nitroprusside. ADMA was measured by high-performance liquid chromatography and insulin resistance (IR by HOMA. Newly diagnosed T2D patients showed higher ADMA and l-arginine mean values in comparison with normal subjects and a significantly reduced ACh-stimulated forearm blood flow (FBF. In T2D patients FBF was significantly and inversely correlated with ADMA (r = −0.524, p < 0.0001 and in a multivariate regression analysis, ADMA resulted the stronger predictor of FBF, explaining the 27.5% of variability (p < 0.0001. In conclusion, ADMA was strongly related to endothelial dysfunction also in patients with newly diagnosed T2D, without clinically manifest vascular complications. This field is of great interest for understanding the mechanisms underlying the pathogenesis of diabetic disease and its CV complications.

The Development Needs of Newly Appointed Senior School Leaders in the Western Cape South Africa: A Case Study

2017-12-01

Full Text Available The essential role that senior school leaders play in school leadership teams to ensure effective strategic leadership in schools has been the subject of intense discussion for many years. Crucial to this debate is the establishment of professional learning and leadership approaches for newly appointed senior school leaders. Recommendations for policy and practice highlight the importance of appropriate, multifaceted, developmental support initiatives for newly appointed school leaders. In many countries, including South Africa, a teaching qualification and, in most cases, extensive teaching experience is the only requirement for being appointed as a senior school leader in a school. This tends to suggest that no further professional development is required for newly appointed school leaders, the problem addressed in this paper. This paper reports on the main findings of the perceived development needs of newly appointed senior school leaders in the Western Cape, South Africa, and suggests that school leaders occupy a unique and specialist role in education, which requires relevant and specific preparation to support effective leadership. The respondents of this study report a lack of contextualised training and support before and after their appointment in their new roles creating unique development needs. This paper, therefore, employs a mixed-method approach to gather data to understand the perceived needs of twenty newly appointed senior school leaders in the Western Cape, South Africa.

Full Text Available Background: Screening newly arrived migrants from countries with high burden of communicable diseases of public health significance is part of the Swedish national strategy against the spread of these diseases. However, little is known about its implementation. Objective: This study aimed at exploring caregivers’ experiences in screening newly arrived migrants to generate knowledge that could inform policy and clinical practice. Design: Using an interpretive description framework, we conducted semistructured interviews between November and December 2011 in four Swedish counties, with 15 purposively selected nurses with experience in screening migrants. Data were analyzed using thematic analysis. Results: Participants described a range of challenges including discordant views between migrants and the nurses about medical screening, inconsistencies in rules and practices, and conflicting policies. Participants indicated that sociocultural differences resulted in divergent expectations with migrants viewing the participants as agents of migration authorities. They also expressed concern over being given a new assignment without training and being expected to share responsibilities with staff from other agencies without adequate coordination. Finally, they indicated that existing policies can be confusing and raise ethical issues. All these were compounded by language barriers, making their work environment extremely complex and stressful. Conclusions: These findings illuminate complex challenges that could limit access to, uptake, and delivery of health screening and undermine public health goals, and highlight the need for a multilevel approach. This entails avoiding the conflation of migration with health issues, harmonizing existing policies to make health care services more accessible and acceptable to migrants, and facilitating health professionals’ work in promoting public health, improving interagency collaboration and the skills of all

Measuring stress in Hispanic Americans, the fastest growing U.S. minority, is problematic. The Life Events Inventory (LEI) and the Daily Hassles Scale (DHS), widely used stress instruments, are not available in Spanish. To test the psychometric properties of the translated Spanish versions of the LEI and DHS. A convenience sample of 63 Hispanic women completed both instruments in Spanish and English 2 weeks apart. Internal consistency reliability and stability were strong for both instruments (.85-.97). Reliability and validity evidence for the translated Spanish versions were strong and similar to the English version. Psychometric findings suggest that the newly translated Spanish versions are good representations of the English versions and that these newly translated instruments are ready for use.

An accident occurred at the Fukushima Dai-ichi Nuclear Power Plant in March 2011 at which time large amounts of radionuclides were released into the atmosphere and the sea. In early May 2011, it was found that newly emerged tea (Camellia sinensis) leaves contained radiocesium, both 134 Cs and 137 Cs in some areas more than 300 km away from the Fukushima plant. To understand the mechanisms of radiocesium transfer to newly emerged tissues (shoots, leaves and fruits) of other plants in the future, radiocesium concentrations in newly emerged leaves of 14 plant species collected from the sampling areas in and near National Institute of Radiological Sciences in Chiba, Japan. The studied plant types were: (1) herbaceous plants, (2) woody plants with no old leaves at the time of the March accident, and (3) woody plants with old leaves out before the accident. About 40–50 d after the start of the accident, newly emerged leaves from woody plant with old leaves tended to show higher values than other woody or herbaceous plants. Concentrations of radiocesium in newly emerged tissues of trees decreased with time, but they did not decrease to the level of herbaceous plants. The type of the plant and presence of old leaves at the time of the heavy deposition period affected the radiocesium concentrations in newly emerged tissues.

In many parts of the world, newly hired science teachers' practices are developing in a complex policy environment. However, little is known about how newly hired science teachers' practices are enacted throughout a cycle of instruction and how these practices can be influenced by macro-, meso-, and micro-policies. Knowing how policies impact practice can result in better policies or better support for certain policies in order to enhance the instruction of newly hired teachers. This comparative study investigated how 12 newly hired science teachers at sites in South Africa (SA) and the United States (US) progressed through an instructional cycle of planning, teaching, and reflection. The qualitative data were analysed through beginning teacher competency frameworks, the cycle of instruction, and institutional theory. Data analysis revealed prevailing areas of practice and connections to levels of policy within the instructional cycle phases. There were some differences between the SA and US teachers and among first-, second-, and third-year teachers. More importantly, this study indicates that newly hired teachers are susceptible to micro-policies and are progressively developing their practice. It also shows the importance of meso-level connectors. It suggests that teacher educators and policy makers must consider how to prepare and support newly hired science teachers to achieve the shared global visions of science teaching.

To explore an association with survival of modifying the current standard of care for patients with newly diagnosed glioblastoma of surgery followed by radiotherapy plus concurrent and 6 cycles of maintenance temozolomide chemotherapy (TMZ/RT → TMZ) by extending TMZ beyond 6 cycles. The German Glioma Network cohort was screened for patients with newly diagnosed glioblastoma who received TMZ/RT → TMZ and completed ≥6 cycles of maintenance chemotherapy without progression. Associations of clinical patient characteristics, molecular markers, and residual tumor determined by magnetic resonance imaging after 6 cycles of TMZ with progression-free survival (PFS) and overall survival (OS) were analyzed with the log-rank test. Multivariate analyses using the Cox proportional hazards model were performed to assess associations of prolonged TMZ use with outcome. Sixty-one of 142 identified patients received at least 7 maintenance TMZ cycles (median 11, range 7-20). Patients with extended maintenance TMZ treatment had better PFS (20.5 months, 95% confidence interval [CI] 17.7-23.3, vs 17.2 months, 95% CI 10.2-24.2, p = 0.035) but not OS (32.6 months, 95% CI 28.9-36.4, vs 33.2 months, 95% CI 25.3-41.0, p = 0.126). However, there was no significant association of prolonged TMZ chemotherapy with PFS (hazard ratio [HR] = 0.8, 95% CI 0.4-1.6, p = 0.559) or OS (HR = 1.6, 95% CI 0.8-3.3, p = 0.218) adjusted for age, extent of resection, Karnofsky performance score, presence of residual tumor, O 6 -methylguanine DNA methyltransferase (MGMT) promoter methylation status, or isocitrate dehydrogenase ( IDH ) mutation status. These data may not support the practice of prolonging maintenance TMZ chemotherapy beyond 6 cycles. This study provides Class III evidence that in patients with newly diagnosed glioblastoma, prolonged TMZ chemotherapy does not significantly increase PFS or OS. © 2017 American Academy of Neurology.

Full Text Available This research is focused on the newly packaged tourist performing arts; they are anew concept and seem to be different from the general tourist performing arts. They arepackaged from various components of Balinese arts and managed as large scale-touristperforming arts in terms of materials, space, and time of their performances. The researchercalls them new types of Bali tourist performing arts because how they are presented isnew and different from the traditional tourist performing arts which are simply performed.In this research, the newly-packaged performing arts are analyzed in the perspective ofcultural studies.The research was carried out at three palaces in Bali; they are Mengwi Palace inBadung regency, Anyar Palace at Kerambitan, Tabanan regency, and Banyuning Palace atBongkasa, Badung regency. There are three main problems to be discussed: firstly, how dothe tourist performing arts emerge in all the palaces? Secondly, are they related to thetourist industry developed in the palaces?, thirdly, what is the impact and meaning of themfor the sake of the palaces, society, and Balinese culture?

Full Text Available Diabetic retinopathy is a common complication of type II diabetes mellitus and carries with it the threat of blindness. Accurate information regarding the incidence of diabetic retinopathy and associated risk factors is important in the prevention of its development and of the visual impairment caused by this complication. This study was designed to determine the prevalence of diabetic retinopathy in newly diagnosed patients with type II diabetes mellitus. We have also evaluated the association of diabetic retinopathy with clinical and biochemical variables. In a cross-sectional study, 152 consecutive patients with newly diagnosed type II diabetes mellitus were referred from two outpatient clinics in Tehran for ophthalmologic exam to detect retinopathy. Indirect ophthalmoscopy was performed and data regarding risk factors were extracted from routine medical records. Chi square and Mann Whitney U tests were used to analyze the data. The overall prevalence of diabetic retinopathy was 13.8 %( 21 cases: three cases with microaneurysm only, 10 with mild, 5 with moderate and 2 with severe non proliferative diabetic retinopathy. Only one patient had advanced proliferative retinopathy. The prevalence of diabetic retinopathy was positively associated with age, duration of disease, fasting plasma glucose, HbA1c, and systolic blood pressure. Diabetic retinopathy is common in newly diagnosed type II diabetes mellitus patients. Ophthalmologic consultation is essential at the time of diagnosis for all patients.

On the Matching of Seen and Felt Shape by Newly Sighted Subjects

John Schwenkler

2012-04-01

Full Text Available How do we recognize identities between seen shapes and felt ones? Is this due to associative learning, or intrinsic connections these sensory modalities? We can address this question by testing the capacities of newly sighted subjects to match seen and felt shapes, but only if the subjects can see the objects well enough to form adequate visual representations of their shapes. In light of this, a recent study by R. Held and colleagues fails to demonstrate that their newly sighted subjects' inability to match seen and felt shape was due to a lack of intermodal connections rather than a purely visual deficit, as the subjects may not have been able visually to represent 3D shape in the perspective-invariant manner required for intermodal matching. However, the study could be modified in any of several ways to help avoid this problem.

There are many studies on spatial distributions of Asari clam Ruditapes philippinarum adults on tidal flats but few have dealt with spatial distributions of newly settled Asari clam (physical/topographical conditions on tidal flats. We examined small-scale spatial distributions of newly settled individuals on the Matsunase tidal flat, central Japan, during the low spring tides on two days 29th-30th June 2007, together with the shear stress from waves and currents on the flat. The characteristics of spatial distribution of newly settled Asari clam markedly varied depending on both of hydrodynamic and topographical conditions on the tidal flat. Using generalized linear models (GLMs), factors responsible for affecting newly settled Asari clam density and its spatial distribution were distinguished between sampling days, with "crest" sites always having a negative influence each on the density and the distribution on both sampling days. The continuously recorded data for the wave-current flows at the "crest" site on the tidal flat showed that newly settled Asari clam, as well as bottom sediment particles, at the "crest" site to be easily displaced. Small-scale spatial distributions of newly settled Asari clam changed with more advanced benthic stages in relation to the wave shear stress.

Chronic kidney disease (CKD) is gradually recognized as an independent risk factor for cardiovascular and cardio-/cerebrovascular disease. This study aimed to examine the association of the estimated glomerular filtration rate (eGFR) and clinical outcomes at 3 months after the onset of ischemic stroke in a hospitalized Chinese population.Totally, 972 patients with acute ischemic stroke were enrolled into this study. Modified of Diet in Renal Disease (MDRD) equations were used to calculate eGFR and define CKD. The site and degree of the stenosis were examined. Patients were followed-up for 3 months. Endpoint events included all-cause death and newly ischemic events. The multivariate logistic model was used to determine the association between renal dysfunction and patients' outcomes.Of all patients, 130 patients (13.4%) had reduced eGFR (<60 mL/min/1.73 m), and 556 patients had a normal eGFR (≥90 mL/min/1.73 m). A total of 694 patients suffered from cerebral artery stenosis, in which 293 patients only had intracranial artery stenosis (ICAS), 110 only with extracranial carotid atherosclerotic stenosis (ECAS), and 301 with both ICAS and ECAS. The patients with eGFR <60 mL/min/1.73m had a higher proportion of death and newly ischemic events compared with those with a relatively normal eGFR. Multivariate analysis revealed that a baseline eGFR <60 mL/min/1.73 m increased the risk of mortality by 3.089-fold and newly ischemic events by 4.067-fold. In further analysis, a reduced eGFR was associated with increased rates of mortality and newly events both in ICAS patients and ECAS patients. However, only an increased risk of newly events was found as the degree of renal function deteriorated in ICAS patients (odds ratio = 8.169, 95% confidence interval = 2.445-14.127).A low baseline eGFR predicted a high mortality and newly ischemic events at 3 months in ischemic stroke patients. A low baseline eGFR was also a strong independent predictor for newly

2014-01-01

This study examines the process by which newly recruited nuclear engineering and technical staff came to understand, define, think, feel and behave within a distinct group that has a direct contribution to the organization's overall emphasis on a culture of reliability and system safety. In the field of organizational behavior the interactive model of social identity formation has been recently proposed to explain the process by which the internalization of shared norms and values occurs, an element critical in identity formation. Using this rich model of organizational behavior we analyzed multiple sources of data from nine new hires over a period of three years. This was done from the time they were employed to investigate the construction of social identity by new entrants entering into a complex organizational setting reflected in the context of a nuclear facility. Informed by our data analyses, we found support for the interactive model of social identity development and report the unexpected finding that a newly appointed member's age and level of experience appears to influence the manner in which they adapt, and assimilate into their surroundings. This study represents an important contribution to the safety and reliability literature as it provides a rich insight into the way newly recruited employees enact the process by which their identities are formed and hence act, particularly under conditions of duress or significant organizational disruption in complex organizational settings. - Highlights: • We examined how newly recruited nuclear engineer staff develop their social identity. • The study empirically examined the interactive model of social identity formation. • Innovative research strategies were used to capture rich primary data for all case studies. • Age and experience moderated internalization route and the social identity formation process

Optimal Remanufacturing Certification Contracts in the Electrical and Electronic Industry

Full Text Available While remanufacturing is highly encouraged worldwide, some original equipment manufacturers (OEMs in the electrical and electronics industry are still not willing to embrace remanufacturing, for fear of expensive investment or the cannibalization of existing products. Meanwhile, third-party remanufacturers’ (TPRs remanufactured products are developing quickly. Due to quality reasons, consumers usually have a higher preference for OEM-certified remanufactured products than uncertified ones. As such, remanufacturing certification has become a strategy that OEMs can use to benefit from product remanufacturing. Our paper focuses on the remanufacturing certification contract between an OEM and a TPR. Once certified, the TPR makes payments to the OEM. These payment terms will affect their enthusiasm for participating in remanufacturing certification. By establishing game models among an OEM, a certified TPR, and an uncertified TPR, our paper explores three certification contracts, namely, the lump-sum payment, profit-sharing payment, and piece-rate payment. We identify the conditions for the OEM and certified TPR to reach a win-win outcome. Our results show that when TPRs have a high profit margin and there is no significant difference in consumers’ preferences between certified and non-certified remanufacturing channels, the profit-sharing payment contract yields the highest profit; otherwise, the piece-rate payment contract is best for the OEM.

2018-05-01

This study investigates the development of Topic-Specific Pedagogical Content Knowledge (TSPCK) of 14 novice uncertified graduate science teachers during a Professional Development Intervention (PDI) on teaching particulate nature of matter. TSPCK was defined in terms of five knowledge components: learner prior knowledge, curricular saliency, representations, what is difficult to teach and conceptual teaching strategies. Data sources consisted of validated pre- and post-TSPCK and content knowledge (CK) tests, teacher-constructed Content Representations (CoRes) before and after teaching and, for four teachers, video-recorded lessons, and field notes together with teacher interviews. The purpose of this study was to investigate how the teachers develop TSPCK through the process. The results provide an insight into how initial construction of CoRes enabled the entire group to start thinking about how to teach the topic. For the four case-study teachers, evidence of TSPCK development was observed in their teaching. These teachers showed greater improvement in TSPCK and CK than those who taught only the prerequisite concepts of the topic. The findings show that it is possible for uncertified teachers to develop PCK in the practice context with appropriate PDI. Some improvement in PCK was also observed for the larger group who taught only prerequisite concepts.

In this work a series of computational fluid dynamics (CFD) simulations were performed to predict the deposition of particles on a newly designed passive dry deposition (Pas-DD) sampler. The sampler uses a parallel plate design and a conventional polyurethane foam (PUF) disk as the deposition surface. The deposition of particles with sizes between 0.5 and 10 μm was investigated for two different geometries of the Pas-DD sampler for different wind speeds and various angles of attack. To evaluate the mean flow field, the k-ɛ turbulence model was used and turbulent fluctuating velocities were generated using the discrete random walk (DRW) model. The CFD software ANSYS-FLUENT was used for performing the numerical simulations. It was found that the deposition velocity increased with particle size or wind speed. The modeled deposition velocities were in general agreement with the experimental measurements and they increased when flow entered the sampler with a non-zero angle of attack. The particle-size dependent deposition velocity was also dependent on the geometry of the leading edge of the sampler; deposition velocities were more dependent on particle size and wind speeds for the sampler without the bend in the leading edge of the deposition plate, compared to a flat plate design. Foam roughness was also found to have a small impact on particle deposition. Copyright © 2016 Elsevier Ltd. All rights reserved.

Bone scanning (BS), liver ultrasonography (LUS), and chest radiography (CXR) are commonly recommended for baseline staging in patients with newly diagnosed breast cancer. The purpose of this study is to demonstrate whether these tests are indicated for specific patient subpopulation based on clinical staging and molecular subtype. A retrospective study on 5406 patients with newly diagnosed breast cancer was conducted to identify differences in occurrence of metastasis based on clinical staging and molecular subtypes. All patients had been evaluated by BS, LUS and CXR at diagnosis. Complete information on clinical staging was available in 5184 patients. For stage I, II, and III, bone metastasis rate was 0%, 0.6% and 2.7%, respectively (P diagnosed breast cancer.

Depression among newly admitted Australian nursing home residents.

McSweeney, K; O'Connor, D W

This research concerns the prevalence and course of depression in newly admitted nursing home residents. We attempted to recruit consecutive admissions into the study, irrespective of cognitive status, enabling a comparison of the prevalence and course of depression experienced by cognitively intact residents and those exhibiting all levels of cognitive impairment. Depression was assessed at one month, three months and six months post-admission. The assessment of mood in this study entailed the conduct of a semi-structured clinical interview, which encompassed DSM-IV criteria and Cornell Scale for Depression in Dementia (CSDD) items. Recruitment difficulties resulted in a sample of 51 newly admitted residents, drawn from six nursing homes located in Victoria, Australia. Of particular interest, throughout the duration of the study, only the cognitively impaired were diagnosed with major depression (MD). One month post-admission, 24% of the sample were diagnosed with MD, and a further 20% evidenced a non-major depressive disorder. At the second and third assessments, MD was observed in 14% and 15% of residents, respectively. For residents who completed all three assessments, there was no appreciable change in the proportion diagnosed with a depressive disorder, nor was there a change in the levels of depressive symptomatology. Although subject to limitations, the current study indicated that clinical depression in nursing home facilities most often occurs in residents who also exhibit pronounced cognitive impairment. These depressions are unlikely to remit spontaneously. Accordingly, care staff and general practitioners must be trained in the identification of depression in dementia, and any interventions implemented in these facilities should be tailored to meet the unique needs of this group.

To identify existing orientation patterns and to find elements that may enhance or impede successful orientation of newly graduated nurses. Preceptors have first-hand information concerning orientation and their opinions should not be forgotten when organisations develop their orientation processes. An open-ended questionnaire was undertaken to collect data from preceptors (n = 172) about the current orientation patterns. Data were analysed by using deductive content analysis and by quantifying the phrases. Communal commitment to the orientation process, strong professional orientation know-how and supportive leadership were the enhancing elements of successful orientation. Complex interpersonal relationship problems during orientation, inadequate orientation resources and the organisation's structural and functional problems were the impeding elements of successful orientation. With the elements of successful orientation we ensure a supportive transition to practice for newly graduate nurses and possibilities to focus on good orientation practices for preceptors. Nurse leaders play an important part in ensuring newly graduated nurses have a safe nursing career starting point and, for preceptors, opportunities to provide orientation that is as good as possible. Supportive leadership, sufficient resources and good interpersonal relationships should be the leading principles during newly graduated nurses' orientation period. © 2017 John Wiley & Sons Ltd.

Science.gov (United States)

Kwon, So Young

Using a quasi-experimental design, the researcher investigated the comparative effects of individually-generated and collaboratively-generated computer-based concept mapping on middle school science concept learning. Qualitative data were analyzed to explain quantitative findings. One hundred sixty-one students (74 boys and 87 girls) in eight, seventh grade science classes at a middle school in Southeast Texas completed the entire study. Using prior science performance scores to assure equivalence of student achievement across groups, the researcher assigned the teacher's classes to one of the three experimental groups. The independent variable, group, consisted of three levels: 40 students in a control group, 59 students trained to individually generate concept maps on computers, and 62 students trained to collaboratively generate concept maps on computers. The dependent variables were science concept learning as demonstrated by comprehension test scores, and quality of concept maps created by students in experimental groups as demonstrated by rubric scores. Students in the experimental groups received concept mapping training and used their newly acquired concept mapping skills to individually or collaboratively construct computer-based concept maps during study time. The control group, the individually-generated concept mapping group, and the collaboratively-generated concept mapping group had equivalent learning experiences for 50 minutes during five days, excepting that students in a control group worked independently without concept mapping activities, students in the individual group worked individually to construct concept maps, and students in the collaborative group worked collaboratively to construct concept maps during their study time. Both collaboratively and individually generated computer-based concept mapping had a positive effect on seventh grade middle school science concept learning but neither strategy was more effective than the other.

The generated iPSCs expressed pluripotent markers and differentiated into all three germ layer lineages. The protocol...

Bioorthogonal Chemistry for the Isolation and Study of Newly Synthesized Histones and Their Modifications.

Arnaudo, Anna M; Link, A James; Garcia, Benjamin A

2016-03-18

The nucleosome is an octamer containing DNA wrapped around one histone H3-H4 tetramer and two histone H2A-H2B dimers. Within the nucleosome, histones are decorated with post-translational modifications. Previous studies indicate that the H3-H4 tetramer is conserved during DNA replication, suggesting that old tetramers serve as a template for the modification of newly synthesized tetramers. Here, we present a method that merges bioorthogonal chemistry with mass spectrometry for the study of modifications on newly synthesized histones in mammalian cells. HeLa S3 cells are dually labeled with the methionine analog azidohomoalanine and heavy (13)C6,(15)N4 isotope labeled arginine. Heavy amino acid labeling marks newly synthesized histones while azidohomoalanine incorporation allows for their isolation using bioorthogonal ligation. Labeled mononucleosomes were covalently linked via a copper catalyzed reaction to a FLAG-GGR-alkyne peptide, immunoprecipitated, and subjected to mass spectrometry for quantitative modification analysis. Mononucleosomes containing new histones were successfully isolated using this approach. Additionally, the development of this method highlights the potential deleterious effects of azidohomoalanine labeling on protein PTMs and cell cycle progression, which should be considered for future studies utilizing bioorthogonal labeling strategies in mammalian cells.

Current projections for the need for nurses in Washington state are based on an increase in the need for health care, the aging of the population, and the inability of the nursing educational institutions to supply adequate numbers of graduates. Yet many new graduates are providing anecdotal evidence that they cannot find a job in nursing. This study gathered information regarding the employment of newly licensed registered nurses in Washington between May 2009 and August 2010. Questionnaires were administered to a randomly selected sample of 2,200 newly licensed nurses; 532 responses were returned. Nearly 81% reported current employment as a registered nurse and 69.5% reported that they were very or somewhat satisfied with their employment situation. The job search strategies, type of job sought, and factors contributing to their success are reported. Factors contributing to the success of their job search and to job dissatisfaction are explored.

Lenke, Nils; Roudet, Nicolas; Tilton, Hereward

2014-02-01

The authors provide a transcription, translation, and evaluation of nine newly discovered letters from the alchemist Michael Maier (1568-1622) to Gebhardt Johann von Alvensleben (1576-1631), a noble landholder in the vicinity of Magdeburg. Stemming from the final year of his life, this correspondence casts new light on Maier's biography, detailing his efforts to secure patronage amid the financial crisis of the early Thirty Years' War. While his ill-fated quest to perfect potable gold continued to form the central focus of his patronage suits, Maier also offered his services in several arts that he had condemned in his printed works, namely astrology and "supernatural" magic. Remarks concerning his previously unknown acquaintance with Heinrich Khunrath call for a re-evaluation of Maier's negotiation of the discursive boundaries between Lutheran orthodoxy and Paracelsianism. The letters also reveal Maier's substantial contribution to a work previously ascribed solely to the English alchemist Francis Anthony.

Recent measurements of capture and total cross sections performed at the Rensselaer Polytechnic Institute in the USA confirmed many of the gadolinium thermal and resonant neutron cross section parameters within uncertainties, but they also showed up important discrepancies well out of uncertainties, such as an approx11% overestimation of the {sup 157}Gd thermal capture cross section in ENDF/B-VI and -VII with respect to the newly measured data. In this work, the impact of the newly measured gadolinium cross sections on BWR reactor physics parameters has been preliminarily evaluated. The comparisons of rod-by-rod fission rate and modified conversion ratio predictions with selected cold critical experiments at the PROTEUS reactor in Switzerland show the potential to resolve long-term unexplained discrepancies.

Transport stress affects the animal's metabolism and psychological state. As a pro-survival pathway, the heat shock response (HSR) protects healthy cells from stressors. However, it is unclear whether the HSR plays a role in transport stress-induced heart damage. To evaluate the effects of transport stress on heart damage and HSR protection, newly hatched chicks were treated with transport stress for 2 h, 4 h and 8 h. Transport stress caused decreases in body weight and increases in serum creatine kinase (CK) activity, nitric oxide (NO) content in heart tissue, cardiac nitric oxide syntheses (NOS) activity and NOS isoforms transcription. The mRNA expression of heat shock factors (HSFs, including HSF1-3) and heat shock proteins (HSPs, including HSP25, HSP40, HSP47, HSP60, HSP70, HSP90 and HSP110) in the heart of 2 h transport-treated chicks was upregulated. After 8 h of transport stress in chicks, the transcription levels of the same HSPs and HSF2 were reduced in the heart. It was also found that the changes in the HSP60, HSP70 and HSP90 protein levels had similar tendencies. These results suggested that transport stress augmented NO generation through enhancing the activity of NOS and the transcription of NOS isoforms. Therefore, this study provides new evidence that transport stress induces heart damage in the newly hatched chicks by blocking the cytoprotective HSR and augmenting NO production.

Highlights: • Analyses of CO 2 emissions and cost in different generation energy source. • Solar, geothermal and wave energy are opportunity for reducing CO 2 emissions. • Expanding renewable energy support electrical industry sustainable development. - Abstract: This study sought to evaluate newly introduced energy policies with regard to economic development and environmental preservation by analyzing carbon dioxide emissions and the costs associated with various electrical power generation schemes. Nonlinear regression was used to measure the efficiency of technology aimed at CO 2 emission reduction and the Morris method was employed for sensitivity analysis. Our results indicate that new Taiwanese energy policies represent the lowest possible cost and the lowest possible CO 2 emissions per kW h currently possible. However, total CO 2 emissions under this plan fail to meet emissions targets established in 2000. This paper outlines a long-term plan for the transformation of the Taiwanese power generation industry from a major contributor of pollution into a largely green entity through the replacement of coal with renewable energy sources

Registered nurses across the globe bear a heavy injury burden. Every shift, nurses are exposed to a variety of hazards that can jeopardize their health, which negatively impacts their ability to provide high-quality patient care. Previous research suggests that inexperienced, or newly licensed nurses, may have an increased risk for certain occupational injuries. However, the current knowledge base is insufficient to fully understand how work hours influence newly licensed nurses' occupational injury, given the significant variation in hospital organization and work characteristics. To describe newly licensed nurses' shift work characteristics and determine the association between shift type and scheduling characteristics and nurse injury, before and after adjusting for individual and combined effects of demographics, external context, organizational context, and work context, following the Organization of Work model. This study is a secondary analysis of a nationally representative survey of newly licensed registered nurses using a cross-sectional design. The analytic sample includes 1744 newly licensed registered nurses from 34 states and the District of Columbia who reported working in a hospital and were within 6-18 months of passing their state licensure exam at the time of survey administration. Descriptive statistics were calculated, followed by bivariate and multivariate Poisson regression models to assess the relationship between shift type and scheduling characteristics and nurse injury. Lastly, full models with the addition of demographics, external context, organizational context, and work context variables were calculated. The majority (79%) of newly licensed nurses worked 12-h shifts, a near majority worked night shift (44%), and over half (61%) worked overtime (mandatory or voluntary) weekly. Nurses working weekly overtime were associated with a 32% [incidence rate ratio (IRR) 1.32, CI 1.07-1.62] increase in the risk of a needle stick and nurses

A genomic audit of newly-adopted autosomal STRs for forensic identification.

Phillips, C

2017-07-01

In preparation for the growing use of massively parallel sequencing (MPS) technology to genotype forensic STRs, a comprehensive genomic audit of 73 STRs was made in 2016 [Parson et al., Forensic Sci. Int. Genet. 22, 54-63]. The loci examined included miniSTRs that were not in widespread use, but had been incorporated into MPS kits or were under consideration for this purpose. The current study expands the genomic analysis of autosomal STRs that are not commonly used, to include the full set of developed miniSTRs and an additional 24 STRs, most of which have been recently included in several supplementary forensic multiplex kits for capillary electrophoresis. The genomic audit of these 47 newly-adopted STRs examined the linkage status of new loci on the same chromosome as established forensic STRs; analyzed world-wide population variation of the newly-adopted STRs using published data; assessed their forensic informativeness; and compiled the sequence characteristics, repeat structures and flanking regions of each STR. A further 44 autosomal STRs developed for forensic analyses but not incorporated into commercial kits, are also briefly described. Copyright © 2017 Elsevier B.V. All rights reserved.

2014-02-01

e-Learning plays an increasingly important role in medical education. Much research has focused on the evaluation of individual modules among medical students or more senior trainee doctors. We studied the attitude of newly qualified foundation level-1 doctors (FY1s) towards a blended learning programme to gain insight into the perceived role of e-learning in relation to classroom and experiential learning. The blended learning strategy consisted of weekly 3-hour sessions of lectures and flexible e-learning sessions. A questionnaire survey was conducted among 54 per cent (37/69) of FY1 doctors, towards the end of their first year post qualification. The majority of FY1s had to carry out additional e-learning outside of work. When asked where was best to carry out e-learning, 54 per cent preferred to e-learn both at work and at home, whereas 38 per cent preferred to e-learn outside of work exclusively. An equal preference for a classroom-only strategy and a blended programme was reported. Seventy-three per cent of the FY1s thought that e-learning should not be part of their compulsory weekly teaching programme. Fifty-four per cent of FY1s thought that e-learning had been useful for their education and training in their FY1 year. The e-learning package cited as being most useful was the safe prescribing e-programme, pioneered locally. Newly qualified doctors value e-learning as an adjunct to experiential and lecture-based teaching, and most prefer it as part of a blended learning programme at work or at home. Medical educators must place equal emphasis on the delivery and administration of e-learning as well as on the course design. © 2014 John Wiley & Sons Ltd.

Patients with breast cancer usually present varying levels of depressive symptoms. Emotional suppression, as a coping style, refers to an individual's ability to consciously control expression of negative emotions. Thus, emotional suppression is an important psychological factor related to depressive symptoms in patients with breast cancer. It has long been considered that compared to European and American women, Chinese women are more likely to ascribe to norms of negative emotion control for smooth social interaction. However, there is paucity of research focusing on emotional suppression among Chinese women with breast cancer. Thus the aims of the current study were (1) to investigate the incidence of depressive symptoms in women newly diagnosed with early breast cancer in Mainland China, and (2) to examine the relationships between emotional suppression and depressive symptoms in these patients. The Center for Epidemiological Studies Depression Scale (CES-D), the Beck Anxiety Inventory (BAI) and the Chinese version of the Courtauld Emotional Control Scale (CECS) were used to assess the level of depressive symptoms, anxiety symptoms and emotional suppression respectively in 247 women with early breast cancer and 362 healthy women. Analyses of variance were conducted to investigate group differences on depressive symptoms and emotional suppression. Bivariate correlations and Hierarchical regression analyses were performed to examine the effect of emotional suppression on depressive symptoms in participants after controlling the impact of group membership and anxiety level. (1) The incidence rates of clinical and severe depressive symptoms in patients were 36.4 and 36.0 % respectively. (2) Patients scored significantly higher than healthy women on CECS. (3) The scores on CECS were significantly associated with the total CES-D scores in all participants; Anger suppression significantly predicted the total CES-D scores. The majority of women newly diagnosed with

Newly released EIA-law. A palette of wishes?; Das neue UVP-Recht. Ein Wunschkonzert?

The EU-directive on Environmental Impact Assessment (EIA) for certain public and private projects was once again amended in 2014 after controversial discussions, three previous modifications during 1985 and 2010 and an aggregation of all amendments within the EU-EIA-2011/92 directive. This newly released EU-EIA-directive 2014/52/EU (hereinafter RL 2014/52) is published within the EU-official journal EU L 124 p. 1 from 25.04.2014, came into force on 15. May 2014 and has to be adopted into international law until 16.05.2017. The modifications made are also valid, apart from certain exceptions, for licensing procedures (including decommissioning of nuclear power plants) in the field of nuclear energy, as far as they might have possible, significant environmental effects. The European EIA directive's 30th ''anniversary'' on 27.06.2015 raises the question, which substantial changes will come soon along with the newly released EU-EIA law. All in all it seems like if authorities and industry might get along with the newly released EU-EIA regulations. The responsible Federal Ministry for the Environment is already working on a first preliminary draft. It is under consideration if the EIA-regulation should be submitted additionally, beyond required amendments by EU-law, to a general revision. EIA-law remains exciting.

Siobhan Conroy

Full Text Available Molecular signatures in Glioblastoma (GBM have been described that correlate with clinical outcome and response to therapy. The Proneural (PN and Mesenchymal (MES signatures have been identified most consistently, but others including Classical (CLAS have also been reported. The molecular signatures have been detected by array techniques at RNA and DNA level, but these methods are costly and cannot take into account individual contributions of different cells within a tumor. Therefore, the aim of this study was to investigate whether subclasses of newly diagnosed GBMs could be assessed and assigned by application of standard pathology laboratory procedures. 123 newly diagnosed GBMs were analyzed for the tumor cell expression of 23 pre-identified proteins and EGFR amplification, together allowing for the subclassification of 65% of the tumors. Immunohistochemistry (IHC-based profiling was found to be analogous to transcription-based profiling using a 9-gene transcriptional signature for PN and MES subclasses. Based on these data a novel, minimal IHC-based scheme for subclass assignment for GBMs is proposed. Positive staining for IDH1R132H can be used for PN subclass assignment, high EGFR expression for the CLAS subtype and a combined high expression of PTEN, VIM and/or YKL40 for the MES subclass. The application of the proposed scheme was evaluated in an independent tumor set, which resulted in similar subclass assignment rates as those observed in the training set. The IHC-based subclassification scheme proposed in this study therefore could provide very useful in future studies for stratification of individual patient samples.

The aim of the study was to create a hybrid forecasting method that could produce higher accuracy forecasts than previously used 'pure' time series methods. Mentioned methods were already tested with total automotive waste, hazardous automotive waste, and total medical waste generation, but demonstrated at least a 6% error rate in different cases and efforts were made to decrease it even more. Newly developed hybrid models used a random start generation method to incorporate different time-series advantages and it helped to increase the accuracy of forecasts by 3%-4% in hazardous automotive waste and total medical waste generation cases; the new model did not increase the accuracy of total automotive waste generation forecasts. Developed models' abilities to forecast short- and mid-term forecasts were tested using prediction horizon.

Laboratory model study of newly deposited dredger fills using improved multiple-vacuum preloading technique

Full Text Available Problems continue to be encountered concerning the traditional vacuum preloading method in field during the treatment of newly deposited dredger fills. In this paper, an improved multiple-vacuum preloading method was developed to consolidate newly dredger fills that are hydraulically placed in seawater for land reclamation in Lingang Industrial Zone of Tianjin City, China. With this multiple-vacuum preloading method, the newly deposited dredger fills could be treated effectively by adopting a novel moisture separator and a rapid improvement technique without sand cushion. A series of model tests was conducted in the laboratory for comparing the results from the multiple-vacuum preloading method and the traditional one. Ten piezometers and settlement plates were installed to measure the variations in excess pore water pressures and moisture content, and vane shear strength was measured at different positions. The testing results indicate that water discharge–time curves obtained by the traditional vacuum preloading method can be divided into three phases: rapid growth phase, slow growth phase, and steady phase. According to the process of fluid flow concentrated along tiny ripples and building of larger channels inside soils during the whole vacuum loading process, the fluctuations of pore water pressure during each loading step are divided into three phases: steady phase, rapid dissipation phase, and slow dissipation phase. An optimal loading pattern which could have a best treatment effect was proposed for calculating the water discharge and pore water pressure of soil using the improved multiple-vacuum preloading method. For the newly deposited dredger fills at Lingang Industrial Zone of Tianjin City, the best loading step was 20 kPa and the loading of 40–50 kPa produced the highest drainage consolidation. The measured moisture content and vane shear strength were discussed in terms of the effect of reinforcement, both of which indicate

This paper presents a virtual reality system (the BlindAid) developed for orientation and mobility training of people who are newly blind. The BlindAid allows users to interact with different virtual structures and objects via auditory and haptic feedback. This case study aims to examine if and how the BlindAid, in conjunction with a traditional rehabilitation programme, can help people who are newly blind develop new orientation and mobility methods. Follow-up research based on this study, with a large experiment and control group, could contribute to the area of orientation and mobility rehabilitation training for the newly blind. The case study research focused on A., a woman who is newly blind, for 17 virtual sessions spanning ten weeks, during the 12 weeks of her traditional orientation and mobility rehabilitation programme. The research was implemented by using virtual environment (VE) exploration and orientation tasks in VE and physical spaces. The research methodology used both qualitative and quantitative methods, including interviews, questionnaire, videotape recording, and user computer logs. The results of this study helped elucidate several issues concerning the contribution of the BlindAid system to the exploration strategies and learning processes experienced by the participant in her encounters with familiar and unfamiliar physical surroundings.

Newly graduated nurses use of knowledge sources in clinical decison-making - a qualitative study

DEFF Research Database (Denmark)

Voldbjerg, Siri

Evidence-based practice has been introduced internationally as a standard for healthcare delivery to improve the quality of care, thus ensuring safe care and treatment. Evidence-based practice calls for a decision-making that specifically requires nurses to place the patient at the centre...... of clinical decisions, based on transparent, articulate and reflective use of knowledge sources. Furthermore, it is implied that nurses are able to retrieve, asses, implement and evaluate research evidence. To meet these requirements, nursing educations around the world have organised curricula to educate...... and support future nurses, enabling them to work within a framework of evidence-based practice. Recent studies underline that despite curricula interventions, newly graduated nurses’ use of research evidence and components within evidence-based practice is limited. However, it is unclear why the newly...

Different selective pressures lead to different genomic outcomes as newly-formed hybrid yeasts evolve

Directory of Open Access Journals (Sweden)

Piotrowski Jeff S

2012-04-01

Full Text Available Abstract Background Interspecific hybridization occurs in every eukaryotic kingdom. While hybrid progeny are frequently at a selective disadvantage, in some instances their increased genome size and complexity may result in greater stress resistance than their ancestors, which can be adaptively advantageous at the edges of their ancestors' ranges. While this phenomenon has been repeatedly documented in the field, the response of hybrid populations to long-term selection has not often been explored in the lab. To fill this knowledge gap we crossed the two most distantly related members of the Saccharomyces sensu stricto group, S. cerevisiae and S. uvarum, and established a mixed population of homoploid and aneuploid hybrids to study how different types of selection impact hybrid genome structure. Results As temperature was raised incrementally from 31°C to 46.5°C over 500 generations of continuous culture, selection favored loss of the S. uvarum genome, although the kinetics of genome loss differed among independent replicates. Temperature-selected isolates exhibited greater inherent and induced thermal tolerance than parental species and founding hybrids, and also exhibited ethanol resistance. In contrast, as exogenous ethanol was increased from 0% to 14% over 500 generations of continuous culture, selection favored euploid S. cerevisiae x S. uvarum hybrids. Ethanol-selected isolates were more ethanol tolerant than S. uvarum and one of the founding hybrids, but did not exhibit resistance to temperature stress. Relative to parental and founding hybrids, temperature-selected strains showed heritable differences in cell wall structure in the forms of increased resistance to zymolyase digestion and Micafungin, which targets cell wall biosynthesis. Conclusions This is the first study to show experimentally that the genomic fate of newly-formed interspecific hybrids depends on the type of selection they encounter during the course of evolution

Evidence has shown that endoplasmic reticulum (ER) stress was involved in the progression to type 2 diabetes mellitus (T2DM) and development of insulin resistance. Mesencephalic astrocyte-derived neurotrophic factor (MANF) is a novel secreted protein upregulated by ER stress. This study aimed to assess serum level of MANF in normal glucose tolerance (NGT) participants and newly diagnosed prediabetic and T2DM patients. A total of 257 participants with NGT, newly diagnosed prediabetes or T2DM were recruited from Yinchao and Hangtian communities of Chengdu, Sichuan, China. Serum MANF level was quantified by enzyme-linked immunosorbent assay (ELISA). The mean age for the 257 participants (147 females) was 62±8 years (range 44-78): 71 with NGT, 115 with newly diagnosed prediabetes and 71 with T2DM. Mean serum MANF level was significantly higher with newly diagnosed prediabetes and T2DM than NGT (2.89±1.09 and 3.03±1.73 vs 2.13±1.37 ng/mL, both pprediabetes patients. We concluded that serum MANF level was higher in patients with newly diagnosed prediabetes and T2DM than in NGT controls. MANF appears to be associated with Matsuda Index, QUICKI and HOMA-IR in prediabetes patients.

Using spatiotemporal models and distance sampling to map the space use and abundance of newly metamorphosed Western Toads (Anaxyrus boreas)

High variability in abundance, cryptic coloration, and small body size of newly metamorphosed anurans have limited demographic studies of this life-history stage. We used line-transect distance sampling and Bayesian methods to estimate the abundance and spatial distribution of newly metamorphosed Western Toads (Anaxyrus boreas) in terrestrial habitat surrounding a montane lake in central Washington, USA. We completed 154 line-transect surveys from the commencement of metamorphosis (15 September 2009) to the date of first snow accumulation in fall (1 October 2009), and located 543 newly metamorphosed toads. After accounting for variable detection probability associated with the extent of barren habitats, estimates of total surface abundance ranged from a posterior median of 3,880 (95% credible intervals from 2,235 to 12,600) in the first week of sampling to 12,150 (5,543 to 51,670) during the second week of sampling. Numbers of newly metamorphosed toads dropped quickly with increasing distance from the lakeshore in a pattern that differed over the three weeks of the study and contradicted our original hypotheses. Though we hypothesized that the spatial distribution of toads would initially be concentrated near the lake shore and then spread outward from the lake over time, we observed the opposite. Ninety-five percent of individuals occurred within 20, 16, and 15 m of shore during weeks one, two, and three respectively, probably reflecting continued emergence of newly metamorphosed toads from the lake and mortality or burrow use of dispersed individuals. Numbers of toads were highest near the inlet stream of the lake. Distance sampling may provide a useful method for estimating the surface abundance of newly metamorphosed toads and relating their space use to landscape variables despite uncertain and variable probability of detection. We discuss means of improving the precision of estimates of total abundance.

Passive appendages generate drift through symmetry breaking

2014-10-01

Plants and animals use plumes, barbs, tails, feathers, hairs and fins to aid locomotion. Many of these appendages are not actively controlled, instead they have to interact passively with the surrounding fluid to generate motion. Here, we use theory, experiments and numerical simulations to show that an object with a protrusion in a separated flow drifts sideways by exploiting a symmetry-breaking instability similar to the instability of an inverted pendulum. Our model explains why the straight position of an appendage in a fluid flow is unstable and how it stabilizes either to the left or right of the incoming flow direction. It is plausible that organisms with appendages in a separated flow use this newly discovered mechanism for locomotion; examples include the drift of plumed seeds without wind and the passive reorientation of motile animals.

Anecdotal evidence suggests that second-generation antipsychotic agents are increasingly used to treat sleep problems. This study sought to quantify the proportion of new prescriptions for second-generation antipsychotic agents started for sleep/sedation and the correlates of such use. A cross-sectional survey of provider decision making at the time second-generation antipsychotic agents were prescribed, documenting the reasons for the medication, patient demographics, psychiatric and medical diagnoses, patient health characteristics, and provider background. A single Veterans Affairs Medical Center over a 20-month period. Prescribers of second-generation antipsychotic agents. N/A. Seven hundred seven (32.2%) of 2,613 surveys indicated sleep/sedation was at least one reason for using a second-generation anti-psychotic agent, whereas for 266 (12.1%) it was the only reason. Quetiapine was most frequently prescribed overall as well as for sleep/sedation (47.0% and 73.6% respectively). Second-generation antipsychotic agent use for sleep/sedation was unrelated to sociodemographic characteristics, least likely in patients with schizophrenia or bipolar disorder, and most likely as a newly started second-generation antipsychotic agent. Sleep/sedation is a common reason given for new prescriptions of second-generation antipsychotic agents. Quetiapine is most frequently used for this purpose. A greater understanding of why providers use second-generation antipsychotic agents rather than safer and less costly alternatives for sleep problems may advance the development of interventions to reduce adverse effects.

Generation of functional organs from patients' own cells is one of the ultimate goals of regenerative medicine. As a novel approach to creation of organs from pluripotent stem cells (PSCs), we employed blastocyst complementation in organogenesis-disabled animals and successfully generated PSC-derived pancreas and kidneys. Blastocyst complementation, which exploits the capacity of PSCs to participate in forming chimeras, does not, however, exclude contribution of PSCs to the development of tissues-including neural cells or germ cells-other than those specifically targeted by disabling of organogenesis. This fact provokes ethical controversy if human PSCs are to be used. In this study, we demonstrated that forced expression of Mix-like protein 1 (encoded by Mixl1) can be used to guide contribution of mouse embryonic stem cells to endodermal organs after blastocyst injection. We then succeeded in applying this method to generate functional pancreas in pancreatogenesis-disabled Pdx1 knockout mice using a newly developed tetraploid-based organ-complementation method. These findings hold promise for targeted organ generation from patients' own PSCs in livestock animals.

Full Text Available Abstract Background The newt Notophthalmus viridescens possesses the remarkable ability to respond to cardiac damage by formation of new myocardial tissue. Surprisingly little is known about changes in gene activities that occur during the course of regeneration. To begin to decipher the molecular processes, that underlie restoration of functional cardiac tissue, we generated an EST database from regenerating newt hearts and compared the transcriptional profile of selected candidates with genes deregulated during zebrafish heart regeneration. Results A cDNA library of 100,000 cDNA clones was generated from newt hearts 14 days after ventricular injury. Sequencing of 11520 cDNA clones resulted in 2894 assembled contigs. BLAST searches revealed 1695 sequences with potential homology to sequences from the NCBI database. BLAST searches to TrEMBL and Swiss-Prot databases assigned 1116 proteins to Gene Ontology terms. We also identified a relatively large set of 174 ORFs, which are likely to be unique for urodele amphibians. Expression analysis of newt-zebrafish homologues confirmed the deregulation of selected genes during heart regeneration. Sequences, BLAST results and GO annotations were visualized in a relational web based database followed by grouping of identified proteins into clusters of GO Terms. Comparison of data from regenerating zebrafish hearts identified biological processes, which were uniformly overrepresented during cardiac regeneration in newt and zebrafish. Conclusion We concluded that heart regeneration in newts and zebrafish led to the activation of similar sets of genes, which suggests that heart regeneration in both species might follow similar principles. The design of the newly established newt EST database allows identification of molecular pathways important for heart regeneration.

To evaluate the effect of short-term intensive insulin treatment on β-cell function in newly diagnosed type 2 diabetes patients with apparently hyperglycemia, twenty-four newly diagnosed type 2 diabetes patients with FPG more than 12.0 mmol/L were treated by short-term transient intensive insulin in average 9.04-4.8 days. Their β-cell function was assessed by oral glucose tolerance test. The FPG, HbAlc and HOMA IR of patients were significantly decreased (P<0.01), while the insulin, the Area Under Curve (AUC) of insulin and HOMA β were significantly increased (P<0.01) after the treatment with insulin. Improvement of β-cell function can be induced by short-term intensive insulin treatment for newly diagnosed type 2 diabetes patients with apparently hyperglycemia. (authors)

2018-04-01

Full Text Available This study investigates the item properties of a newly developed Automatic Number Series Item Generator (ANSIG. The foundation of the ANSIG is based on five hypothesised cognitive operators. Thirteen item models were developed using the numGen R package and eleven were evaluated in this study. The 16-item ICAR (International Cognitive Ability Resource1 short form ability test was used to evaluate construct validity. The Rasch Model and two Linear Logistic Test Model(s (LLTM were employed to estimate and predict the item parameters. Results indicate that a single factor determines the performance on tests composed of items generated by the ANSIG. Under the LLTM approach, all the cognitive operators were significant predictors of item difficulty. Moderate to high correlations were evident between the number series items and the ICAR test scores, with high correlation found for the ICAR Letter-Numeric-Series type items, suggesting adequate nomothetic span. Extended cognitive research is, nevertheless, essential for the automatic generation of an item pool with predictable psychometric properties.

Full Text Available Sequential fault diagnosis is an approach that realizes fault isolation by executing the optimal test step by step. The strategy used, i.e., the sequential diagnostic strategy, has great influence on diagnostic accuracy and cost. Optimal sequential diagnostic strategy generation is an important step in the process of diagnosis system construction, which has been studied extensively in the literature. However, previous algorithms either are designed for single mode systems or do not consider test placement cost. They are not suitable to solve the sequential diagnostic strategy generation problem considering test placement cost for multimode systems. Therefore, this problem is studied in this paper. A formulation is presented. Two algorithms are proposed, one of which is realized by system transformation and the other is newly designed. Extensive simulations are carried out to test the effectiveness of the algorithms. A real-world system is also presented. All the results show that both of them have the ability to solve the diagnostic strategy generation problem, and they have different characteristics.

Environmental contamination caused by heavy metals poses a major threat to the wildlife and human health for their toxicity and intrinsically persistent nature. Some specific food grade bacteria have properties that enable them to eliminate heavy metals from food and water. Lactococcus lactis subsp. lactis, newly isolated from pickles, is a cadmium (Cd) tolerant bacteria. Cd resistant properties of the lactis was evaluated under different Cd stresses. Cd accumulation in different cellular parts was determined by ICP-MS and cell morphology changes were measured by SEM-EDS and TEM-EDS. In addition, functional groups associated with Cd resistance were detected by infrared spectroscopic analysis. The results indicated that Cd mainly accumulated in the cell surface structures including cytoderm and cytomembrane. Functional groups such as OH and NH 2 in the cell surface played essential roles in Cd biosorption. The elements of O, P, S, and N of polysaccharide, membrane protein and phosphatidate in the cell surface structures might be responsible for Cd biosorption for their strong electronegativity. This study indicated that ultrastructural analysis can be a supplemental method to study heavy metal resistance mechanism of microorganism and the newly isolated lactococcus lactis subsp. lactis has great potential to be applied to decontamination of heavy metals.

Haladin, Ivo; Lakušić, Stjepan; Ahac, Maja

2017-09-01

Rail vehicles in interaction with a railway structure induce vibrations that are propagating to surrounding structures and cause noise disturbance in the surrounding areas. Since tram tracks in urban areas often share the running surface with road vehicles one of top priorities is to achieve low maintenance and long lasting structure. Research conducted in scope of this paper gives an overview of newly designed tram track structures designated for use on Zagreb tram network and their performance in terms of noise and vibration mitigation. Research has been conducted on a 150 m long test section consisted of three tram track types: standard tram track structure commonly used on tram lines in Zagreb, optimized tram structure for better noise and vibration mitigation and a slab track with double sleepers embedded in a concrete slab, which presents an entirely new approach of tram track construction in Zagreb. Track has been instrumented with acceleration sensors, strain gauges and revision shafts for inspection. Relative deformations give an insight into track structure dynamic load distribution through the exploitation period. Further the paper describes vibro-acoustic measurements conducted at the test site. To evaluate the track performance from the vibro-acoustical standpoint, detailed analysis of track decay rate has been analysed. Opposed to measurement technique using impact hammer for track decay rate measurements, newly developed measuring technique using vehicle pass by vibrations as a source of excitation has been proposed and analysed. Paper gives overview of the method, it’s benefits compared to standard method of track decay rate measurements and method evaluation based on noise measurements of the vehicle pass by.

Resilience is the individual's ability to bounce back from trauma. It has been studied for some time in the U.S., but few studies in China have addressed this important construct. In mainland China, relatively little is known about the resilience of patients in clinical settings, especially among patients with breast cancer. In this study, we aimed to evaluate the level of resilience and identify predictors of resilience among mainland Chinese women newly diagnosed with breast cancer. A cross-sectional descriptive study was conducted with 213 mainland Chinese women newly diagnosed with breast cancer between November 2014 and June 2015. Participants were assessed with the Connor-Davidson Resilience Scale (CD-RISC), Social Support Rating Scale (SSRS), Medical Coping Modes Questionnaire (MCMQ, including 3 subscales: confrontation, avoidance, and acceptance-resignation), Herth Hope Index (HHI), and demographic and disease-related information. Descriptive statistics, bivariate analyses and multiple stepwise regression were conducted to explore predictors for resilience. The average score for CD-RISC was 60.97, ranging from 37 to 69. Resilience was positively associated with educational level, family income, time span after diagnosis, social support, confrontation, avoidance, and hope. However, resilience was negatively associated with age, body mass index (BMI), and acceptance-resignation. Multiple stepwise regression analysis indicated that hope (β = 0.343, Pconfrontation (β = 0.187, P = 0.001), and age (β = -0.108, P = 0.037) significantly affected resilience and explained 50.1% of the total variance in resilience. Women with newly diagnosed breast cancer from mainland China demonstrated particularly low resilience level, which was predicted by hope educational level, avoidance, confrontation, and age.

Chlumecký, Martin; Buchtele, Josef; Richta, Karel

2017-10-01

The efficient calibration of rainfall-runoff models is a difficult issue, even for experienced hydrologists. Therefore, fast and high-quality model calibration is a valuable improvement. This paper describes a novel methodology and software for the optimisation of a rainfall-runoff modelling using a genetic algorithm (GA) with a newly prepared concept of a random number generator (HRNG), which is the core of the optimisation. The GA estimates model parameters using evolutionary principles, which requires a quality number generator. The new HRNG generates random numbers based on hydrological information and it provides better numbers compared to pure software generators. The GA enhances the model calibration very well and the goal is to optimise the calibration of the model with a minimum of user interaction. This article focuses on improving the internal structure of the GA, which is shielded from the user. The results that we obtained indicate that the HRNG provides a stable trend in the output quality of the model, despite various configurations of the GA. In contrast to previous research, the HRNG speeds up the calibration of the model and offers an improvement of rainfall-runoff modelling.

The role of infections and coinfections with newly identified and emerging respiratory viruses in children

Full Text Available Abstract Acute respiratory infections are a major cause of morbidity in children both in developed and developing countries. A wide range of respiratory viruses, including respiratory syncytial virus (RSV, influenza A and B viruses, parainfluenza viruses (PIVs, adenovirus, rhinovirus (HRV, have repeatedly been detected in acute lower respiratory tract infections (LRTI in children in the past decades. However, in the last ten years thanks to progress in molecular technologies, newly discovered viruses have been identified including human Metapneumovirus (hMPV, coronaviruses NL63 (HcoV-NL63 and HKU1 (HcoV-HKU1, human Bocavirus (HBoV, new enterovirus (HEV, parechovirus (HpeV and rhinovirus (HRV strains, polyomaviruses WU (WUPyV and KI (KIPyV and the pandemic H1N1v influenza A virus. These discoveries have heavily modified previous knowledge on respiratory infections mainly highlighting that pediatric population is exposed to a variety of viruses with similar seasonal patterns. In this context establishing a causal link between a newly identified virus and the disease as well as an association between mixed infections and an increase in disease severity can be challenging. This review will present an overview of newly recognized as well as the main emerging respiratory viruses and seek to focus on the their contribution to infection and co-infection in LRTIs in childhood.

To evaluate the prevalence of primary aldosteronism (PA) in newly diagnosed and untreated hypertensive patients in primary care using the aldosterone/renin ratio (ARR), and to assess clinical and biochemical characteristics in patients with high and normal ARR. Patient survey study. A total of 200 consecutive patients with newly diagnosed and untreated hypertension from six primary health care centres in Sweden were included. ARR was calculated from serum aldosterone and plasma renin concentrations. The cut-off level for ARR was 65. Patients with an increased ARR were considered for confirmatory testing with the fludrocortisone suppression test (FST), followed by adrenal computed tomographic radiology (CT) and adrenal venous sampling (AVS). Of 200 patients, 36 patients had an ARR > 65. Of these 36 patients, 11 patients had an incomplete aldosterone inhibition during FST. Three patients were diagnosed with an aldosterone producing adenoma (APA) and eight with bilateral adrenal hyperplasia (BHA). Except for moderately lower level of P-K in patients with an ARR > 65 and in patients with PA, there were no biochemical or clinical differences found among hypertensive patients with PA compared with patients without PA. Eleven of 200 evaluated patients (5.5%) were considered to have PA. The diagnosis of PA should therefore be considered in newly diagnosed hypertensive subjects and screening for the diagnosis is warranted.

To explore clinical characteristics and beta cell function in Chinese patients with newly diagnosed drug naive type 2 diabetes mellitus (T2DM) with different levels of serum triglyceride (TG). Patients with newly diagnosed T2DM (n = 624) were enrolled and divided into different groups according to levels of serum TG. All patients underwent oral glucose tolerance tests and insulin releasing tests. Demographic data, lipid profiles, glucose levels, and insulin profiles were compared between different groups. Basic insulin secretion function index (homeostasis model assessment for beta cell function index, HOMA-β), modified beta cell function index (MBCI), glucose disposition indices (DI), and early insulin secretion function index (insulinogenic index, IGI) were used to evaluate the beta cell function. Patients of newly diagnosed T2DM with hypertriglyceridemia were younger, fatter and had worse lipid profiles, glucose profiles, and high insulin levels than those with normal TG. There is no difference in early phase insulin secretion among groups of newly diagnosed T2DM patients with different TG levels. The basal beta cell function (HOMA-β and MBCI) initially increased along rising TG levels and then decreased as the TG levels rose further. The insulin sensitivity was relatively high in patients with a low level of TG and low with a high level of TG. Hypertriglyceridemia influences clinical characteristics and β cell function of Chinese patients with newly diagnosed T2DM. A better management of dyslipidemia may, to some extent, reduce the effect of lipotoxicity, thereby improving glucose homeostasis in patients with newly diagnosed T2DM.

Venous thromboembolism (VTE) is a common complication in patients with high-grade gliomas. The purpose of this prospective multicenter study was to determine the hazard rate of first symptomatic VTE in newly-diagnosed glioma patients and identify clinical and laboratory risk factors. On enrollment, demographic and clinical information were recorded and a comprehensive coagulation evaluation was performed. Patients were followed until death. The study end point was objectively-documented symptomatic VTE. One hundred seven patients were enrolled with a median age of 57 years (range 29-85) between June 2005 and April 2008. Ninety-one (85 %) had glioblastoma multiforme (GBM). During an average survival of 17.7 months, 26 patients (24 %) (95 % CI 17-34 %) developed VTE (hazard rate 0.15 per person-year) and 94 patients (88 %) died. Median time to VTE was 14.2 weeks post-operation (range 3-126). Patients with an initial tumor biopsy were 3.0 fold more likely to suffer VTE (p = 0.02). Patients with an elevated factor VIII activity (>147 %) were 2.1-fold more likely to develop VTE. ABO blood group, D dimer and thrombin generation were not associated with VTE. No fatal VTE occurred. VTE is a common complication in patients with newly-diagnosed high grade gliomas, particularly in the first six months after diagnosis. Patients with an initial tumor biopsy and elevated factor VIII levels are at increased risk. However, VTE was not judged to be primarily responsible for any patient deaths. Therefore, outpatient primary VTE prophylaxis remains investigational until more effective primary prophylaxis strategies and therapies for glioma are identified.

We report the first evidence for a large-scale reconnection exhaust newly initiated in the solar wind using observations from three spacecraft: ACE, Wind, and ARTEMIS P2. We identified a well-structured X-line exhaust using measurements from ARTEMIS P2 in the downstream solar wind. However, in the upstream solar wind, ACE detected the same current sheet that corresponds to the exhaust identified by ARTEMIS P2 data without showing any reconnection signals. We cannot find any reconnection signals from Wind located between ACE and ARTEMIS P2. Within the exhaust, a magnetic island is identified, which is not consistent with the quasi-steady feature as previously reported and provides further evidence that the reconnection is newly initiated. Our observations show that the entering of energetic particles, probably from Earth's bow shock, makes the crucial difference between the non-reconnecting current sheet and the exhaust. Since no obvious driving factors are responsible for the reconnection initiation, we infer that these energetic particles probably play an important role in the reconnection initiation. Theoretical analysis also shows support for this potential mechanism

There are regional differences in the burden of tuberculosis (TB). Although these differences might be explained by regional differences in the risk factors of TB, whether such risk factors are actually associated with the regional differences in the TB burden remains unclear. This study aimed to investigate the relationship between the risk factors of and regional differences in TB incidence. A cohort study applying nationwide claims database in Republic of Korea included patients newly diagnosed with type 2 diabetes mellitus (DM) in 2009. The main outcome was the incidence of TB defined based on the diagnostic codes combined with anti-tuberculosis treatment repeated within 90 days. Sixteen regions were categorized into 3 groups according to the age- and sex-standardized TB incidence rates. Multivariate logistic regression analysis adjusted for risk factors was performed to identify the determinants of the regional differences in TB incidence. Among 331 601 participants newly diagnosed with type 2 DM and with no history of previous TB, 1216 TB cases were observed. The regional TB incidence rates ranged between 2.3 and 5.9/1000 patients. Multivariate analyses did not identify any determinants of regional differences in the TB incidence among the various risk factors, including age, sex, health care utilization, co-morbidities, medication and treatment and complications of DM. Similarly, temperature, humidity and latent TB infection rate also did not affect the results. Although substantial regional differences in the TB incidence rate were observed among patients with newly diagnosed DM, no determinants of regional difference were identified among the risk factors. © 2017 John Wiley & Sons Ltd.

Functional diffusion mapping (fDM) is a cancer imaging technique that uses voxel-wise changes in apparent diffusion coefficients (ADC) to evaluate response to treatment. Despite promising initial results, uncertainty in image registration remains the largest barrier to widespread clinical application. The current study introduces a probabilistic approach to fDM quantification to overcome some of these limitations. A total of 143 patients with newly diagnosed glioblastoma who were undergoing standard radiochemotherapy were enrolled in this retrospective study. Traditional and probabilistic fDMs were calculated using ADC maps acquired before and after therapy. Probabilistic fDMs were calculated by applying random, finite translational, and rotational perturbations to both pre-and posttherapy ADC maps, then repeating calculation of fDMs reflecting changes after treatment, resulting in probabilistic fDMs showing the voxel-wise probability of fDM classification. Probabilistic fDMs were then compared with traditional fDMs in their ability to predict progression-free survival (PFS) and overall survival (OS). Probabilistic fDMs applied to patients with newly diagnosed glioblastoma treated with radiochemotherapy demonstrated shortened PFS and OS among patients with a large volume of tumor with decreasing ADC evaluated at the posttreatment time with respect to the baseline scans. Alternatively, patients with a large volume of tumor with increasing ADC evaluated at the posttreatment time with respect to baseline scans were more likely to progress later and live longer. Probabilistic fDMs performed better than traditional fDMs at predicting 12-month PFS and 24-month OS with use of receiver-operator characteristic analysis. Univariate log-rank analysis on Kaplan-Meier data also revealed that probabilistic fDMs could better separate patients on the basis of PFS and OS, compared with traditional fDMs. Results suggest that probabilistic fDMs are a more predictive biomarker in

Real time testing of intelligent relays for synchronous distributed generation islanding detection

Zhuang, Davy

As electric power systems continue to grow to meet ever-increasing energy demand, their security, reliability, and sustainability requirements also become more stringent. The deployment of distributed energy resources (DER), including generation and storage, in conventional passive distribution feeders, gives rise to integration problems involving protection and unintentional islanding. Distributed generators need to be islanded for safety reasons when disconnected or isolated from the main feeder as distributed generator islanding may create hazards to utility and third-party personnel, and possibly damage the distribution system infrastructure, including the distributed generators. This thesis compares several key performance indicators of a newly developed intelligent islanding detection relay, against islanding detection devices currently used by the industry. The intelligent relay employs multivariable analysis and data mining methods to arrive at decision trees that contain both the protection handles and the settings. A test methodology is developed to assess the performance of these intelligent relays on a real time simulation environment using a generic model based on a real-life distribution feeder. The methodology demonstrates the applicability and potential advantages of the intelligent relay, by running a large number of tests, reflecting a multitude of system operating conditions. The testing indicates that the intelligent relay often outperforms frequency, voltage and rate of change of frequency relays currently used for islanding detection, while respecting the islanding detection time constraints imposed by standing distributed generator interconnection guidelines.

Full Text Available Abstract Background Degradation of the toxic compounds generated in the harsh pretreatment of lignocellulose is an inevitable step in reducing the toxin level for conducting practical enzymatic hydrolysis and ethanol fermentation processes. Various detoxification methods have been tried and many negative outcomes were found using these methods, such as the massive freshwater usage and wastewater generation, loss of the fine lignocellulose particles and fermentative sugars and incomplete removal of inhibitors. An alternate method, biodetoxification, which degrades the toxins as part of their normal metabolism, was considered a promising option for the removal of toxins without causing the above problems. Results A kerosene fungus strain, Amorphotheca resinae ZN1, was isolated from the microbial community growing on the pretreated corn stover material. The degradation of the toxins as well as the lignocelluloses-derived sugars was characterized in different ways, and the results show that A. resinae ZN1 utilized each of these toxins and sugars as the sole carbon sources efficiently and grew quickly on the toxins. It was found that the solid-state culture of A. resinae ZN1 on various pretreated lignocellulose feedstocks such as corn stover, wheat straw, rice straw, cotton stalk and rape straw degraded all kinds of toxins quickly and efficiently. The consequent simultaneous saccharification and ethanol fermentation was performed at the 30% (wt/wt solid loading of the detoxified lignocellulosic feedstocks without a sterilization step, and the ethanol titer in the fermentation broth reached above 40 g/L using food crop residues as feedstocks. Conclusions The advantages of the present biodetoxification by A. resinae ZN1 over the known detoxification methods include zero energy input, zero wastewater generation, complete toxin degradation, processing on solid pretreated material, no need for sterilization and a wide lignocellulose feedstock spectrum

We conducted a cross-sectional study to determine the prevalence and risk factors of leukopenia and thrombocytopenia among Chinese adults with newly diagnosed HIV/AIDS. One thousand nine hundred and forty-eight newly diagnosed HIV-infected patients were enrolled between 2009 and 2010. Serum samples obtained from each individual were collected for complete blood count. Factors associated with the presence of leukopenia and thrombocytopenia were analyzed by multiple logistic regression. The overall prevalence of leukopenia and of thrombocytopenia was 33.2% and 15.6%, respectively. The prevalence of leukopenia was higher among females than among males (39.4% versus 31.2%). The prevalence of leukopenia increased with decreasing CD4 count (8.2%, 26.5%, 33.4%, and 41.5% among patients with CD4 count of ≥ 350, 200-349, 50-199, and risk of leukopenia, and that lower CD4 count, and HIV transmission by blood were significantly associated with an increased risk of thrombocytopenia. The study reflects that leukopenia and thrombocytopenia are common among Chinese adults with newly diagnosed HIV/AIDS; and lower CD4 count is associated with an increased risk of both leukopenia and thrombocytopenia. We propose that a routine assessment of these parameters is necessary for timely and adequate clinical management.

Computational identification of cooperative transcription factor (TF) pairs helps understand the combinatorial regulation of gene expression in eukaryotic cells. Many advanced algorithms have been proposed to predict cooperative TF pairs in yeast. However, it is still difficult to conduct a comprehensive and objective performance comparison of different algorithms because of lacking sufficient performance indices and adequate overall performance scores. To solve this problem, in our previous study (published in BMC Systems Biology 2014), we adopted/proposed eight performance indices and designed two overall performance scores to compare the performance of 14 existing algorithms for predicting cooperative TF pairs in yeast. Most importantly, our performance comparison framework can be applied to comprehensively and objectively evaluate the performance of a newly developed algorithm. However, to use our framework, researchers have to put a lot of effort to construct it first. To save researchers time and effort, here we develop a web tool to implement our performance comparison framework, featuring fast data processing, a comprehensive performance comparison and an easy-to-use web interface. The developed tool is called PCTFPeval (Predicted Cooperative TF Pair evaluator), written in PHP and Python programming languages. The friendly web interface allows users to input a list of predicted cooperative TF pairs from their algorithm and select (i) the compared algorithms among the 15 existing algorithms, (ii) the performance indices among the eight existing indices, and (iii) the overall performance scores from two possible choices. The comprehensive performance comparison results are then generated in tens of seconds and shown as both bar charts and tables. The original comparison results of each compared algorithm and each selected performance index can be downloaded as text files for further analyses. Allowing users to select eight existing performance indices and 15

Target-orientated prevention and effective crisis management can reduce or avoid damage and save lives in case of a strong earthquake. To achieve this goal, a project for automatic generated ShakeMaps (maps of ground motion and shaking intensity) and updating the Austrian hazard map was started at ZAMG (Zentralanstalt für Meteorologie und Geodynamik) in 2015. The first goal of the project is set for a near-real-time generation of ShakeMaps following strong earthquakes in Austria to provide rapid, accurate and official information to support the governmental crisis management. Using newly developed methods and software by SHARE (Seismic Hazard Harmonization in Europe) and GEM (Global Earthquake Model), which allows a transnational analysis at European level, a new generation of Austrian hazard maps will be ultimately calculated. More information and a status of our project will be given by this presentation.

Resilience and Associated Factors among Mainland Chinese Women Newly Diagnosed with Breast Cancer.

Full Text Available Resilience is the individual's ability to bounce back from trauma. It has been studied for some time in the U.S., but few studies in China have addressed this important construct. In mainland China, relatively little is known about the resilience of patients in clinical settings, especially among patients with breast cancer. In this study, we aimed to evaluate the level of resilience and identify predictors of resilience among mainland Chinese women newly diagnosed with breast cancer.A cross-sectional descriptive study was conducted with 213 mainland Chinese women newly diagnosed with breast cancer between November 2014 and June 2015. Participants were assessed with the Connor-Davidson Resilience Scale (CD-RISC, Social Support Rating Scale (SSRS, Medical Coping Modes Questionnaire (MCMQ, including 3 subscales: confrontation, avoidance, and acceptance-resignation, Herth Hope Index (HHI, and demographic and disease-related information. Descriptive statistics, bivariate analyses and multiple stepwise regression were conducted to explore predictors for resilience.The average score for CD-RISC was 60.97, ranging from 37 to 69. Resilience was positively associated with educational level, family income, time span after diagnosis, social support, confrontation, avoidance, and hope. However, resilience was negatively associated with age, body mass index (BMI, and acceptance-resignation. Multiple stepwise regression analysis indicated that hope (β = 0.343, P<0.001, educational level of junior college or above (β = 0.272, P<0.001, educational level of high school (β = 0.235, P<0.001, avoidance (β = 0.220, P<0.001, confrontation (β = 0.187, P = 0.001, and age (β = -0.108, P = 0.037 significantly affected resilience and explained 50.1% of the total variance in resilience.Women with newly diagnosed breast cancer from mainland China demonstrated particularly low resilience level, which was predicted by hope educational level, avoidance, confrontation

2005-01-01

The aim of this paper is to report a newly developed micro-computed tomography system for in vivo use. The system was composed of a micro-focus X-ray tube and an image intensifier (I.I.), both of which rotated around the object stage. A guinea pig and a rat were examined. The anesthetized animal was set on the secure object stage. Images of the head of the guinea pig and the tibia knee joint of the rat were taken. In addition, an image of the rat's tail was taken. The reconstruction and the image viewing were carried out using I-View software. The voxel matrix was 512 x 512 x 384. The voxel sizes ranged from 10 x 10 x 10 μm to 100 x 100 x 100 μm. The exposure time was 17 s, and the reconstruction time was 150 s. The head of the guinea pig and the tibia/knee joint of the rat were observed clearly under 100-μm and 30μm voxels, respectively. The trabecular bone of the tail was also observed clearly under a 10 μm voxel. The newly developed micro-computed tomography system makes it possible to obtain images of anesthetized animals set on a secure object stage. Clear bone images of the small animals could be obtained within a short time. (author)

The authors present the time course of the labeling of RNA and protein moieties of these particles in vivo as well as the pattern of one-dimensional acrylamide gel electrophoresis of their protein moieties labeled with (/sup 35/S)methionine in vivo, which shows that released 60 S particles are newly synthesized ribosomal large subunits or their precursor particles in the nucleoplasm on their way from the nucleolus to the cytoplasm. It appears likely that released 40 S particles contain newly synthesized ribosomal small subunits or their precursors in the nucleoplasm.

BACKGROUND: Epidemiologic shift with rising incidence of Crohn\\'s disease (CD) has been reported in recent studies. AIMS: To determine disease behaviour and therapeutic interventions undertaken in newly diagnosed patients with CD. METHODS: Patients diagnosed with CD between January 2006 and June 2008 were included. Disease type, location, degree of involvement and type of therapeutic interventions were recorded. RESULTS: A total of 78 patients were included. Colonic, ileo-colonic, terminal ileal and isolated small bowel disease were present in 37, 27, 9 and 5 patients, respectively. Disease phenotype was inflammatory, stenosing and fistulising in 42, 30 and 6 patients, respectively. Surgery was required in 22 patients, including right hemicolectomy (n = 8), subtotal colectomy (n = 4), segmental colonic resection (n = 2), segmental small bowel resection (n = 2), appendectomy (n = 2) and perianal surgery (n = 4). Fourteen patients underwent surgery at the time of diagnosis. Laparoscopic surgery was performed in 14 patients. CONCLUSIONS: A significant proportion of newly diagnosed patients with CD underwent surgical intervention on their first admission to hospital. This may signify a changing trend in the management approach.

Generation and Verification of ENDF/B-VII.0 Cross section Libraries for Monte Carlo Calculations

International Nuclear Information System (INIS)

Park, Ho Jin; Kwak, Min Su; Joo, Han Gyu; Kim, Chang Hyo

2007-01-01

For Monte Carlo neutronics calculations, a continuous energy nuclear data library is needed. It can be generated from various evaluated nuclear data files such as ENDF/B using the ACER routine of the NJOY.code after a series of prior processing involving various other NJOY routines. Recently, a utility code, which generates the NJOY input decks in an automated mode, named ANJOYMC became available. The use of this code greatly reduces the user's effort and the possibility of input errors. In December 2006, the initial version of the ENDF/BVII nuclear data library was released. It was reported that the new data files have much better data which reduces the errors noted in the previous versions. Thus it is worthwhile to examine the performance of the new data files particularly using an independent Monte Carlo code, MCCARD and the ANJOYMC utility code. The verification of the newly generated library can be readily performed by analyzing numerous standard criticality benchmark problems

The role of increased gluconeogenesis as an important contributor to fasting hyperglycaemia at diabetes onset is not known. We evaluated the contribution of gluconeogenesis and glycogenolysis to fasting hyperglycaemia in newly diagnosed youths with type 2 diabetes following an overnight fast. Basal rates (μmol kg(FFM) (-1) min(-1)) of gluconeogenesis ((2)H2O), glycogenolysis and glycerol production ([(2)H5] glycerol) were measured in 18 adolescents (nine treatment naive diabetic and nine normal-glucose-tolerant obese adolescents). Type 2 diabetes was associated with higher gluconeogenesis (9.2 ± 0.6 vs 7.0 ± 0.3 μmol kg(FFM) (-1) min(-1), p gluconeogenesis, glycogenolysis and glucose production were higher in diabetic youth (p ≤ 0.02). Glycerol concentration (84 ± 6 vs 57 ± 6 μmol/l, p = 0.01) and glycerol production (5.0 ± 0.3 vs 3.6 ± 0.5 μmol kg(FFM) (-1) min(-1), p = 0.03) were 40% higher in youth with diabetes. The increased glycerol production could account for only ~1/3 of substrate needed for the increased gluconeogenesis in diabetic youth. Increased gluconeogenesis was a major contributor to fasting hyperglycaemia and hepatic insulin resistance in newly diagnosed untreated adolescents and was an early pathological feature of type 2 diabetes. Increased glycerol availability may represent a significant source of new carbon substrates for increased gluconeogenesis but would not account for all the carbons required to sustain the increased rates.

Background Lateral epicondylitis is a common cause of pain and upper limb dysfunction. The use of counterforce straps for treatment of lateral epicondylitis is widespread. This kind of orthosis can be modified to have a greater effect on relieving pain by reducing tension on the origin of the extensor pronator muscles. Objectives To determine the immediate effects of a newly designed orthosis on pain and grip strength in patients with lateral epicondylitis. Materials and Methods Twelve participants (six men and six women) were recruited (mean age = 41 ± 6.7 years) and evaluated for pain and grip strength in three sessions. A 48-hour break was taken between each session. The first session was without any orthosis, the second session was with the new modified tennis elbow orthosis, and the third session was with a conventional tennis elbow strap. Results Both counterforce straps were effective. However, significantly more improvement was observed in pain and grip strength after using the newly modified orthosis (P < 0.05). Conclusions The newly designed strap reduces pain more effectively and improves grip strength by causing greater localized pressure on two regions with different force applications (two component vectors versus one).

The first experimental evidence showing the connection between blob/hole formation and zonal-flow generation was obtained in the edge plasma of the JET tokamak. Holes as well as blobs are observed to be born in the edge shear layer, where zonal-flows shear off meso-scale coherent structures......, leading to disconnection of positive and negative pressure perturbations. The newly formed blobs transport azimuthal momentum up the gradient of the azimuthal flow and drive the zonal-flow shear while moving outwards. During this process energy is transferred from the meso-scale coherent structures...

Thermal-hydraulic experiments for the PCHE type steam generator

International Nuclear Information System (INIS)

Shin, C. W.; No, H. C.

2015-01-01

Printed circuit heat exchanger (PCHE) manufactured by HEATRIC is a compact type of the mini-channel heat exchanger. The PCHE is manufactured by diffusion bonding of the chemically-etched plates, and has high heat transfer rate due to a large surface. Therefore, the size of heat exchanger can be reduced by 1/5 - 1/6 and PCHE can be operated under high pressure, high temperature and multi-phase flow. Under such merits, it is used as heat exchanger with various purposes of gas cycle and water cycle. Recently, it is newly suggested as an application of a steam generator. IRIS of MIT and FASES of KAIST conceptually adopted PCHE as a steam generator. When using boiling condition of micro-channel, flow instability is one of the critical issues. Instability may cause unstable mass flow rate, sudden temperature change and system control failure. However instability tests of micro channels using water are very limited because the previous studies were focused on a single tube or other fluid instead of water. In KAIST, we construct the test facility to study the thermal hydraulics and fluid dynamics of the heat exchanger, especially occurrence of instability. By inducing the pressure drop of inlet water, amplitude of oscillation declined by 90%. Finally, the throttling effect was experimentally confirmed that PCHE could be utilized as a steam generator

The present study reports the biosafety assessment, the exact molecular effects, and apoptosis induction of newly developed chitosan-silver hybrid nanoparticles (Cs–Ag NPs) in HepG2 cells. The investigated hybrid NPs were green synthesized using Cs/grape leaves aqueous extract (Cs/GLE) or Cs/GLE NPs as reducing and stabilizing agents. The successful formation of Cs/GLE NPs and Cs–Ag hybrid NPs has been confirmed by UV–Vis spectrophotometry, FTIR spectroscopy, XRD, and HRTEM. From the TEM analysis, the prepared Cs/GLE NPs are uniform and spherical with an average size of 150 nm, and the AgNPs (5–10 nm) were formed mainly on their surface. The UV–Vis spectra of Cs–Ag NPs showed a surface plasmon resonance (SPR) peak at about 450 nm confirming their formation. The synthesized Cs–Ag NPs were found to be crystalline as shown by XRD patterns with fcc phase oriented along the (111), (200), (220), and (311) planes. The cytotoxicity patterns, the antiproliferative activities, and the possible mechanisms of anticancer activity at molecular level of the newly developed Cs–Ag hybrid NPs were investigated. Cytotoxicity patterns of all the preparations demonstrated that the nontoxic treatment concentrations are ranged from 0.39 to 50 %, and many of the newly prepared Cs–Ag hybrid NPs showed high anticancer activities against HpG2 cells, and induced cellular apoptosis by downregulating BCL2 gene and upregulating P53.Graphical Abstract

Localization of foot-and-mouth disease - RNA synthesis on newly formed cellular smooth membranous vacuoles

International Nuclear Information System (INIS)

Polatnick, J.; Wool, S.H.

1982-01-01

Viral RNA synthesis in foot-and-mouth disease infected bovine kidney cell cultures was associated throughout the infectious period with newly formed smooth membranous vacuoles. Membrane formation was measured by choline uptake. The site of RNA synthesis was determined by electron microscopic examination of autoradiograms of incorporated [ 3 H] uridine. Both membrane formation and RNA synthesis became signifcant at 2.5 hours postinfection, but membrane formation increased steadily to 4.5 hours while RNA synthesis peaked at 3.5 hours. Percent density distributions of developed silver grains on autoradiograms showed that almost all RNA synthesis was concentrated on the smooth vacuoles of infected cells. Histogram analysis of grain density distributions established that the site of RNA synthesis was the vacuolar membrane. The newly formed smooth membrane-bound vacuoles were not seen to coalesce into the large vacuolated areas typical of poliovirus cytopathogenicity. (Author)

Keim, V.; Rohr, G.

1987-01-01

The secretion of newly synthesized pancreatic enzymes was studied in pancreatic duct cannulated rats after intravenous injection of 100 microCi of [ 35 S]methionine. Secretion rate was stimulated by intravenous infusion of either cerulein (0.2 microgram/kg h) or carbachol (10 nmol/kg h) starting simultaneously with or 180 min before the injection of the labeled methionine. Secretory proteins were analyzed by sodium dodecyl sulfate (SDS) gel electrophoresis or by nondenaturing gel electrophoresis followed by determination of the radioactivity associated with the individual proteins. Similar to unstimulated controls in all experiments, an early secretion of newly synthesized trypsinogen and chymotrypsinogen was found, whereas amylase and lipase were secreted only after a certain lag period. The results suggest that the intracellular transit of endoproteases is faster than that of other enzymes, irrespective of whether or not secretagogues were applied

Prioritizing patients' information needs maximizes efficiency. This study examined the information sources and priorities in a sample of older adults newly diagnosed with symptomatic myeloma requiring immediate therapy. An association analysis of whether information needs were influenced by sociodemographic variables such as age, gender, education, marital status, and income was also conducted. The Information Needs Questionnaire (INQ) and an investigator-developed interview schedule were administered to 20 older adults diagnosed with symptomatic myeloma during a 30- to 45-minute semistructured interview. We found that older adults newly diagnosed with symptomatic myeloma have different priorities of information needs when compared with younger patients diagnosed with various types of cancer. The top three priorities related to treatment, prognosis, and self-care. Sociodemographic variables did not influence the priorities of information needs among older adults with symptomatic myeloma. The Internet, physicians, family, and friends were among the top sources of information. Advanced practitioners in oncology should support and identify interventions that can enhance patients' learning process from these sources. Well poised to assist patients in searching credible and reliable Internet sources, advanced practitioners in oncology can provide patient education about different treatments and the impact of such treatments on prognosis (e.g., overall survival and likelihood of cure).

Incubation of SR vesicles with Ca 2+ and ( 32 P)acetylphosphate, yields steady state levels of ( 32 P)phosphorylated enzyme (ATPase) intermediate and high concentrations of Ca 2+ in the lumen of the vesicles. At this time, addition of ADP (and EGTA to lower the Ca 2+ concentration in the medium outside the vesicles) results in single cycle formation of (γ- 32 P)ATP by transfer of ( 32 P)phosphate from the enzyme intermediate to ADP. The phosphoenzyme decay and ATP formation exhibit a fast component within the first 20 msec following addition of ADP, and a slower component reaching an asymptote in approximately 100 msec. They have now measured by a rapid filtration method the fraction of newly synthesized ATP which is bound to the enzyme, as opposed to the fraction dissociated into the medium. They find that nearly all the ATP formed during the initial burst is still bound to the enzyme within the initial 20 msec of reaction. Dissociation of newly synthesized ATP occurs then with approximately 13 sec -1 rate constant, permitting reequilibration of the system and further formation of ATP. The rate limiting effect of ATP dissociation and other partial reactions on the slow component of single cycle ATP synthesis is evaluated by appropriate kinetic simulations

Prompt entry to care after HIV diagnosis benefits the infected individual and reduces the likelihood of further transmission of the virus. The New York State HIV Testing Law of 2010 requires diagnosing providers to refer persons newly diagnosed with HIV to follow-up medical care. This study used routinely collected HIV-related laboratory data from the New York State HIV surveillance system to assess whether the fraction of newly diagnosed cases entering care within 90 days of diagnosis increased after the implementation of the law. Laboratory data on 23,302 newly diagnosed cases showed that entry to care within 90 days rose steadily from 72.0% in 2007 to 85.4% in 2012. The rise was observed across all race/ethnic groups, ages, transmission risk groups, sexes, and regions of residence. Logistic regression analyses of entry to care pre-law and post-law, controlling for demographic characteristics, transmission risk, and geographic area, indicate that percentage of newly diagnosed cases entering care within 90 days grew more rapidly in the post-law period. This is consistent with a positive effect of the law on entry to care.

After being diagnosed with lung cancer, patients often experience sleep disturbance, anxiety, depression, and fatigue. These symptoms may occur because of changes in neurotransmitter secretion caused by tumors. This study investigated the correlation of cortisol and melatonin rhythms with sleep quality, anxiety, depression, and fatigue levels in patients with newly diagnosed lung cancer. We conducted a case-control study and recruited 40 patients with newly diagnosed lung cancer and 40 healthy adults. The patient group had a lower salivary melatonin level and flatter slope (p cortisol level and steeper slope (p cortisol slope (p = 0.005) and fatigue score (p = 0.032) predicted the sleep quality score (p = 0.011). Overall, the patients with newly diagnosed lung cancer had poorer sleep quality, higher depression levels, lower salivary melatonin levels, higher cortisol levels, and flatter melatonin and cortisol slopes than did the controls. The fatigue level and cortisol slope significantly predicted sleep quality. Therefore, the assessment of cortisol and melatonin rhythms and levels could provide crucial information that may be beneficial for managing symptoms in patients with newly diagnosed lung cancer.

Full Text Available Ambient Intelligence (AmI joins together the fields of ubiquitous computing and communications, context awareness, and intelligent user interfaces. Energy, fault-tolerance, and mobility are newly added dimensions of AmI. Within the context of AmI the concept of mobile ad hoc networks (MANETs for “anytime and anywhere” is likely to play larger roles in the future in which people are surrounded and supported by small context-aware, cooperative, and nonobtrusive devices that will aid our everyday life. The connection between knowledge generation and communication ad hoc networking is symbiotic—knowledge generation utilizes ad hoc networking to perform their communication needs, and MANETs will utilize the knowledge generation to enhance their network services. The contribution of the present study is a distributed evolving fuzzy modeling framework (EFMF to observe and categorize relationships and activities in the user and application level and based on that social context to take intelligent decisions about MANETs service management. EFMF employs unsupervised online one-pass fuzzy clustering method to recognize nodes' mobility context from social scenario traces and ubiquitously learn “friends” and “strangers” indirectly and anonymously.

Dialysis membranes are often made from synthetic polymers, such as polysulfone. However, membranes made from cellulose triacetate have superior biocompatibility and have been used since the 1980s. On-line hemodiafiltration treatment accompanied by massive fluid replacement is increasingly being used in Europe and Japan, but cellulose triacetate is not suitable for this treatment. Our newly developed asymmetric triacetate membrane, the ATA™ membrane, substantially improved the filtration properties and blood compatibility because of the asymmetric structure and smooth surface of this cellulose acetate membrane. Key Message: The ATA membrane maintains its high permeability even after massive filtration and shows less temporal variation in its permeation performance, lower protein adsorption, and superior biocompatibility compared with conventional membranes. © 2017 S.

Economical photovoltaic power generation with heat recovery

Science.gov (United States)

Ascher, G.

1977-01-01

Three designs for conversion of solar radiation to electricity and thermal energy are analyzed. The objective of these converters is to increase the electric and thermal output for each photovoltaic array so as to lower the cell cost relative to the amount of energy delivered. An analysis of the economical aspects of conversion by photovoltaic cells with heat recovery is carried out in terms of hypothetical examples. Thus, it is shown that the original cost of say $40,000 per generated kilowat can be reduced to $572.00 per kilowatt by increasing the original electric output of 1 kW to 10 kW in electricity and 60 kW in thermal energy. The newly derived specific cost is only 1.4 percent of the original one. It is expected that a cost reduction of roughly 2% of the present specific cost per kilowatt will greatly stimulate public acceptance of photovoltaic terrestrial conversion to electricity.

Construction of a 350 MW Class PFBC (Pressurized Fluidized Bed Combustion) boiler plant is under planning in Japan. Design temperature and pressure of the vessel are maximum 350 C and 1.69 MPa, respectively. As the plate thickness of the vessel exceeds over 100 mm, high strength steel plate of good weldability and less susceptible to reheat cracking was required and developed. The steel was aimed to satisfy the tensile strength over 610 MPa at 350 C after postweld heat treatment (PWHT), with good notch toughness. The authors investigated the welding performances of the newly developed steel by using 150 mm-thick plate welded by pulsed-MAG and SAW methods. It was confirmed that the newly developed steel and its welds possess sufficient strength and toughness after PWHT, and applicable to the actual pressure vessel.

A Column-Generation Approach for a Short-Term Production Planning Problem in Closed-Loop Supply Chains

Directory of Open Access Journals (Sweden)

Florian Sahling

2013-05-01

Full Text Available We present a new model formulation for a multi-product lot-sizing problem with product returns and remanufacturing subject to a capacity constraint. The given external demand of the products has to be satisfied by remanufactured or newly produced goods. The objective is to determine a feasible production plan, which minimizes production, holding, and setup costs. As the LP relaxation of a model formulation based on the well-known CLSP leads to very poor lower bounds, we propose a column-generation approach to determine tighter bounds. The lower bound obtained by column generation can be easily transferred into a feasible solution by a truncated branch-and-bound approach using CPLEX. The results of an extensive numerical study show the high solution quality of the proposed solution approach.

Newly approved antibiotics and antibiotics reserved for resistant infections: Implications for emergency medicine.

Science.gov (United States)

Mazer-Amirshahi, Maryann; Pourmand, Ali; May, Larissa

2017-01-01

Millions of patients are evaluated every year in the emergency department (ED) for bacterial infections. Emergency physicians often diagnose and prescribe initial antibiotic therapy for a variety of bacterial infections, ranging from simple urinary tract infections to severe sepsis. In life-threatening infections, inappropriate choice of initial antibiotic has been shown to increase morbidity and mortality. As such, initiation of appropriate antibiotic therapy on the part of the emergency physician is critical. Increasing rates of antibiotic resistance, drug allergies, and antibiotic shortages further complicates the choice of antibiotics. Patients may have a history of prior resistant infections or culture data indicating that common first-line antibiotics used in the ED may be ineffective. In recent years, there have been several new antibiotic approvals as well as renewed interest in second and third line antibiotics because of the aforementioned concerns. In addition, several newly approved antibiotics have the advantage of being administered once weekly or even as a single infusion, which has the potential to decrease hospitalizations and healthcare costs. This article reviews newly approved antibiotics and antibiotics used to treat resistant infections with a focus on implications for emergency medicine. Copyright © 2016 Elsevier Inc.

The aim of this study was to determine the prognostic value of quantitative fluorodeoxyglucose (FDG) measurements (maximum standardized uptake value [SUV max ], metabolic tumor volume [MTV], and total lesion glycolysis [TLG]) in patients with newly diagnosed metastatic breast cancer (MBC). An IRB-approved retrospective review was performed of patients who underwent FDG positron emission tomography (PET)/computed tomography (CT) from 1/02 to 12/08 within 60 days of diagnosis MBC. Patients with FDG-avid lesions without receiving chemotherapy in the prior 30 days were included. Target lesions in bone, lymph node (LN), liver, and lung were analyzed for SUV max , MTV, and TLG. Medical records were reviewed for patient characteristics and overall survival (OS). Cox regression was used to test associations between quantitative FDG measurements and OS. A total of 253 patients were identified with disease in bone (n = 150), LN (n = 162), liver (n = 48), and lung (n = 66) at the time of metastatic diagnosis. Higher SUV max tertile was associated with worse OS in bone metastases (highest vs. lowest tertile hazard ratio [HR] = 3.1, P < 0.01), but not in LN, liver or lung (all P > 0.1). Higher MTV tertile was associated with worse OS in LN (HR = 2.4, P < 0.01) and liver (HR = 3.0, P = 0.02) metastases, but not in bone (P = 0.22) or lung (P = 0.14). Higher TLG tertile was associated with worse OS in bone (HR = 2.2, P = 0.02), LN (HR = 2.3, P < 0.01), and liver (HR = 4.9, P < 0.01) metastases, but not in lung (P = 0.19). We conclude measures of FDG avidity are prognostic biomarkers in newly diagnosed MBC. SUV max and TLG were both predictors of survival in breast cancer patients with bone metastases. TLG may be a more informative biomarker of OS than SUV max for patients with LN and liver metastases. Measures of fluorodeoxyglucose (FDG) avidity are prognostic biomarkers in newly diagnosed metastatic breast cancer. Volumetric measurements, such as total lesion glycolysis (TLG

Osuji, Charles U.; Omejua, Emeka G.

2012-01-01

Background: Cardiovascular disease risk factors have a tendency to cluster. The presence of such a cluster in an individual has been designated the metabolic syndrome (MetS). There is a paucity of reports of the prevalence of MetS in hypertensive patients in south east Nigeria. This study was undertaken to determine the prevalence of the metabolic syndrome (MetS) among newly diagnosed hypertensive patients using the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria in a tertiary healthcare centre in South East Nigeria. Materials and Methods: A population of 250 consecutive newly diagnosed adult hypertensive patients (126 males and 124 females) was evaluated. Blood pressure and anthropometric measurements were done using standardized techniques. After an overnight fast, blood samples were taken for glucose and lipid profile assays. The NCEP ATP III criteria were then applied for the diagnosis of MetS. Results: The prevalence of the MetS among the study population was 31.2%. The sex-specific prevalences were 15.1% and 47.6% among male and female patients respectively. A large number of the patients (40.4%) were at a high potential risk of developing the MetS as they already met 2 of the criteria. The MetS prevalence increased progressively from 14.3% through 23.8%, in the patients aged 24-33years and 34-43 years, respectively to a peak (40.4%) among those aged 44-53 years before declining in those aged 54-63 years (31.8%), 64-73 years (33.3%) and 74 years and above (20.6%). Central obesity was the most common component of the MetS being present in 50.4% of patients (28.6% of males and 72.6% of females). Of the other components, low HDL-C was present in 38.8% (26.2% of males and 51.6% of females), elevated FBS in 12.8% (6.3% of males and 19.4% of females) and elevated triglycerides in 8.8% (11.9% of males and 5.6% of females). Conclusion: The prevalence of the MetS is high among newly diagnosed hypertensive patients in Nnewi

Low vitamin B12 levels among newly-arrived refugees from Bhutan, Iran and Afghanistan: a multicentre Australian study.

Directory of Open Access Journals (Sweden)

Jill Benson

Full Text Available BACKGROUND: Vitamin B12 deficiency is prevalent in many countries of origin of refugees. Using a threshold of 5% above which a prevalence of low Vitamin B12 is indicative of a population health problem, we hypothesised that Vitamin B12 deficiency exceeds this threshold among newly-arrived refugees resettling in Australia, and is higher among women due to their increased risk of food insecurity. This paper reports Vitamin B12 levels in a large cohort of newly arrived refugees in five Australian states and territories. METHODS: In a cross-sectional descriptive study, we collected Vitamin B12, folate and haematological indices on all refugees (n = 916; response rate 94% of eligible population who had been in Australia for less than one year, and attended one of the collaborating health services between July 2010 and July 2011. RESULTS: 16.5% of participants had Vitamin B12 deficiency (<150 pmol/L. One-third of participants from Iran and Bhutan, and one-quarter of participants from Afghanistan had Vitamin B12 deficiency. Contrary to our hypothesis, low Vitamin B12 levels were more prevalent in males than females. A higher prevalence of low Vitamin B12 was also reported in older age groups in some countries. The sensitivity of macrocytosis in detecting Vitamin B12 deficiency was only 4.6%. CONCLUSION: Vitamin B12 deficiency is an important population health issue in newly-arrived refugees from many countries. All newly-arrived refugees should be tested for Vitamin B12 deficiency. Ongoing research should investigate causes, treatment, and ways to mitigate food insecurity, and the contribution of such measures to enhancing the health of the refugee communities.

Approximately 450,000 legal permanent immigrants and 75,000 refugees enter the United States annually after receiving required medical examinations by overseas panel physicians (physicians who follow the CDC medical screening guidelines provided to the U.S. Department of State). CDC has the regulatory responsibility for preventing the introduction, transmission, and spread of communicable diseases into the United States as well as for developing the guidelines, known as technical instructions, for the overseas medical examinations. Other conditions that are not infectious might preclude an immigrant or refugee from entering the United States and also are reported as part of the medical examination. After arrival in the United States, all refugees are recommended to obtain a medical assessment by a health-care provider or a health department within 30 days. In addition, immigrants with certain medical conditions such as noninfectious tuberculosis at the time of the original medical examination are recommended to be evaluated after arrival to ensure that appropriate prevention or treatment measures are instituted. Health departments need timely and accurate notifications of newly arriving immigrants, refugees, and persons with other visa types to facilitate these evaluations. Notifications for all newly arriving refugees (with or without medical conditions) and immigrants with medical conditions are provided by CDC's Electronic Disease Notification (EDN) system. This is the first report describing EDN. This report summarizes notifications by the EDN system during January-December 2009. The EDN system is a centralized electronic reporting system that collects health information on newly arriving refugees and immigrants with Class A and Class B medical conditions. Class A conditions render applicants inadmissible and require a waiver for entry; Class B conditions are admissible but might require treatment or follow-up.

De Novo generation of molecular structures using optimization to select graphs on a given lattice

DEFF Research Database (Denmark)

Bywater, R.P.; Poulsen, Thomas Agersten; Røgen, Peter

2004-01-01

A recurrent problem in organic chemistry is the generation of new molecular structures that conform to some predetermined set of structural constraints that are imposed in an endeavor to build certain required properties into the newly generated structure. An example of this is the pharmacophore...... model, used in medicinal chemistry to guide de novo design or selection of suitable structures from compound databases. We propose here a method that efficiently links up a selected number of required atom positions while at the same time directing the emergent molecular skeleton to avoid forbidden...... positions. The linkage process takes place on a lattice whose unit step length and overall geometry is designed to match typical architectures of organic molecules. We use an optimization method to select from the many different graphs possible. The approach is demonstrated in an example where crystal...

AUTOMATIC GENERATION OF ROAD INFRASTRUCTURE IN 3D FOR VEHICLE SIMULATORS

Adam Orlický

2017-12-01

Full Text Available One of the modern methods of testing new systems and interfaces in vehicles is testing in a vehicle simulator. Providing quality models of virtual scenes is one of tasks for driver-car interaction interface simulation. Nowadays, there exist many programs for creating 3D models of road infrastructures, but most of these programs are very expensive or canÂtt export models for the following use. Therefore, a plug-in has been developed at the Faculty of Transportation Sciences in Prague. It can generate road infrastructure by Czech standard for designing roads (CSN 73 6101. The uniqueness of this plug-in is that it is the first tool for generating road infrastructure in NURBS representation. This type of representation brings more exact models and allows to optimize transfer for creating quality models for vehicle simulators. The scenes created by this plug-in were tested on vehicle simulators. The results have shown that with newly created scenes drivers had a much better feeling in comparison to previous scenes.

The Nexus between Military Spending and Economic Growth in Newly Industrialized Countries: Panel Evidence from CrossSectional Dependency

Directory of Open Access Journals (Sweden)

Mehmet Akif DESTEK

2016-05-01

Full Text Available In this study, the long term relationship between military spending and economic growth in newly industrialized countries is analyzed with panel data methods for the years of 1988-2013. The study, where panel unit root, panel co-integration, panel co-integration estimator and panel causality tests that allow cross-sectional dependence are used, shows that the feedback hypothesis is valid in newly industrialized countries. And when these countries are analyzed separately, it is seen that the growth hypothesis is valid for India, Malaysia, Mexico and South Africa; the neutrality hypothesis is valid for China, Indonesia, Philippines, Thailand and Turkey and the growth detriment hypothesis is valid for Brazil.

A newly identified myopathy of the internal anal sphincter is described. In the affected family, at least one member from each of five generations had severe proctalgia fugax; onset was usually in the third to fifth decades of life. Three members of the family have been studied in detail. Each had severe pain intermittently during the day and hourly during the night. Constipation was an associated symptom, in particular difficulty with rectal evacuation. Clinically the internal anal sphincter was thickened and of decreased compliance. The maximum anal canal pressure was usually increased with marked ultraslow wave activity. Anal endosonography confirmed a grossly thickened internal anal sphincter. Two patients were treated by internal anal sphincter strip myectomy; one showed marked improvement and one was relieved of the constipation but had only slight improvement of the pain. The hypertrophied muscle in two of the patients showed unique myopathic changes, consisting of vacuolar changes with periodic acid-Schiff-positive polyglycosan bodies in the smooth muscle fibers and increased endomysial fibrosis. In vitro organ-bath studies showed insensitivity of the muscle to noradrenaline, isoprenaline, carbachol, dimethylpiperazinium, and electrical-field stimulation. Immunohistochemical studies for substance P, calcitonin gene-related peptide, galanin, neuropeptide Y, and vasoactive intestinal peptide showed staining in a similar distribution to that in control tissue. A specific autosomal-dominant inherited myopathy of the internal anal sphincter that causes anal pain and constipation has been identified and characterized.

Silicon and iron aluminide (FeAl) nanoparticles were synthesized by a laser vaporization controlled condensation (LVCC) method. The particles generated by the laser ablation of solid targets were transported and deposited in the presence of well-defined thermal and electric field in a newly designed flow-type LVCC chamber. The deposition process of nanoparticles was controlled by the balance of the external forces; i.e., gas flow, thermophoretic and electrostatic forces. The size distributions of generated nanoparticles were analyzed using a low-pressure differential mobility analyzer (LP-DMA). The effect of synthesis condition on the size distribution was analyzed by changing the pressure of the carrier gas (20-200 Torr), the temperature gradient in the LVCC chamber (ΔT=0-190 deg. C) and the electric field applied between the LVCC chamber plates (E=0-3000 V/m). It was found that electrostatic field was effective to selectively deposit small size nanoparticles (about 10 nm) with expelling large droplet-like particles

Layered packaging: A synergistic method of transporting radioactive material

Hohmann, G.L.

1989-01-01

The DOE certification for a transportation cask used to ship radioactive Krypton 85 from the Idaho Chemical Processing Plant (ICPP) to Oak Ridge National Laboratory (ORNL), was allowed to expire in 1987. The Westinghouse Idaho Nuclear Company (WINCO) was charged by DOE with modifying this cask to meet all current NRC requirements and preparing an updated Safety Analysis Report for Packaging, which would be submitted by DOE to the NRC for certification. However, an urgent need arose for ORNL to receive Krypton 85 which was in storage at the ICPP, which would not allow time to obtain certification of the modified shipping cask. WINCO elected to use a layered shipping configuration in which the gaseous Krypton 85 was placed in the uncertified, modified shipping cask to make use of its shielding and thermal insulation properties. This cask was then inserted into the Model No. 6400 (Super Tiger) packaging using a specially constructed plywood box and polyurethane foam dunnage. Structural evaluations were completed to assure the Super Tiger would provide the necessary impact, puncture, and thermal protection during maximum credible accidents. Analyses were also completed to determine the uncertified Krypton shipping cask would provide the necessary containment and shielding for up to 3.7 E+14 Bq of Krypton 85 when packaged inside the Super Tiger. The resulting reports, based upon this layered packaging concept, were adequate to first obtain DOE certification for several restricted shipments of Krypton 85 and then NRC certification for unrestricted shipments

This paper applies Pedroni's panel cointegration approach to explore the causal relationship between trade openness, carbon dioxide emissions, energy consumption, and economic growth for the panel of newly industrialized economies (i.e., Brazil, India, China, and South Africa) over the period of 1970-2013. Our panel cointegration estimation results found majority of the variables cointegrated and confirm the long-run association among the variables. The Granger causality test indicates bidirectional causality between carbon dioxide emissions and energy consumption. A unidirectional causality is found running from trade openness to carbon dioxide emission and energy consumption and economic growth to carbon dioxide emissions. The results of causality analysis suggest that the trade liberalization in newly industrialized economies induces higher energy consumption and carbon dioxide emissions. Furthermore, the causality results are checked using an innovative accounting approach which includes forecast-error variance decomposition test and impulse response function. The long-run coefficients are estimated using fully modified ordinary least square (FMOLS) method, and results conclude that the trade openness and economic growth reduce carbon dioxide emissions in the long run. The results of FMOLS test sound the existence of environmental Kuznets curve hypothesis. It means that trade liberalization induces carbon dioxide emission with increased national output, but it offsets that impact in the long run with reduced level of carbon dioxide emissions.

Newly synthesized histones H3 and H4 undergo a cascade of maturation steps to achieve proper folding and to establish post-translational modifications prior to chromatin deposition. Acetylation of H4 on lysines 5 and 12 by the HAT1 acetyltransferase is observed late in the histone maturation cascade. A key question is to understand how to establish and regulate the distinct timing of sequential modifications and their biological significance. Here, we perform proteomic analysis of the newly synthesized histone H4 complex at the earliest time point in the cascade. In addition to known binding partners Hsp90 and Hsp70, we also identify for the first time two subunits of the histone acetyltransferase inhibitor complex (INHAT): PP32 and SET/TAF-Iβ. We show that both proteins function to prevent HAT1-mediated H4 acetylation in vitro. When PP32 and SET/TAF-Iβ protein levels are down-regulated in vivo, we detect hyperacetylation on lysines 5 and 12 and other H4 lysine residues. Notably, aberrantly acetylated H4 is less stable and this reduces the interaction with Hsp90. As a consequence, PP32 and SET/TAF-Iβ depleted cells show an S-phase arrest. Our data demonstrate a novel function of PP32 and SET/TAF-Iβ and provide new insight into the mechanisms regulating acetylation of newly synthesized histone H4. © The Author(s) 2017.

We have undertaken a survey of molecular lines in the 3 mm band toward 57 young stellar objects using the Australia Telescope National Facility Mopra 22 m radio telescope. The target sources were young stellar objects with active outflows (extended green objects (EGOs)) newly identified from the GLIMPSE II survey. We observe a high detection rate (50%) of broad line wing emission in the HNC and CS thermal lines, which combined with the high detection rate of class I methanol masers toward these sources (reported in Paper I) further demonstrates that the GLIMPSE II EGOs are associated with outflows. The physical and kinematic characteristics derived from the 3 mm molecular lines for these newly identified EGOs are consistent with these sources being massive young stellar objects with ongoing outflow activity and rapid accretion. These findings support our previous investigations of the mid-infrared properties of these sources and their association with other star formation tracers (e.g., infrared dark clouds, methanol masers and millimeter dust sources) presented in Paper I. The high detection rate (64%) of the hot core tracer CH{sub 3}CN reveals that the majority of these new EGOs have evolved to the hot molecular core stage. Comparison of the observed molecular column densities with predictions from hot core chemistry models reveals that the newly identified EGOs from the GLIMPSE II survey are members of the youngest hot core population, with an evolutionary time scale of the order of 10{sup 3} yr.

Sixty-five consecutive patients with newly diagnosed type I diabetes, aged 15-52, were exposed to a systematic educational programme and followed up by three-monthly controls for two to four years. In order to identify psychic, social and behavioural factors associated with good metabolic control...... and appropriate adaptation to illness, they were clinically tested and filled in a questionnaire. The study shows that the illness and the therapeutic regime created few problems regarding practical circumstances of daily living, but there were a vast number of psychological problems: perceived disability......, fatigue, fear, anger, strain, bad conscience, and perceived discrimination. The patients assessed the treatment regimen they had been taught as fair, but still the majority reported inadequate compliance and problems in relation to compliance, especially regarding dietary restrictions.

Adaptive scallop height tool path generation for robot-based incremental sheet metal forming

Science.gov (United States)

Seim, Patrick; Möllensiep, Dennis; Störkle, Denis Daniel; Thyssen, Lars; Kuhlenkötter, Bernd

2016-10-01

Incremental sheet metal forming is an emerging process for the production of individualized products or prototypes in low batch sizes and with short times to market. In these processes, the desired shape is produced by the incremental inward motion of the workpiece-independent forming tool in depth direction and its movement along the contour in lateral direction. Based on this shape production, the tool path generation is a key factor on e.g. the resulting geometric accuracy, the resulting surface quality, and the working time. This paper presents an innovative tool path generation based on a commercial milling CAM package considering the surface quality and working time. This approach offers the ability to define a specific scallop height as an indicator of the surface quality for specific faces of a component. Moreover, it decreases the required working time for the production of the entire component compared to the use of a commercial software package without this adaptive approach. Different forming experiments have been performed to verify the newly developed tool path generation. Mainly, this approach serves to solve the existing conflict of combining the working time and the surface quality within the process of incremental sheet metal forming.

Production and properties of biosurfactants from a newly isolated Pseudomonas fluorescens HW-6 growing on hexandecane

Vasileva-Tonkova, E.; Galabova, D. [Bulgarian Academy of Sciences, Dept. of Microbial Biochemistry, Sofia (Bulgaria); Stoimenova, E.; Lalchev, Z. [Dept. of Biochemistry, Sofia Univ. ' ' St. Kliment Ohridski' ' , Sofia (Bulgaria)

2006-07-15

The newly isolated from industrial wastewater Pseudomonas fluorescens strain HW-6 produced glycolipid biosurfactants at high concentrations (1.4-2.0 g 1{sup -1}) when grown on hexadecane as a sole carbon source. Biosurfactants decreased the surface tension of the air/water interface by 35 mN m{sup -1} and possessed a low critical micelle concentration value of 20 mg 1{sup -1}, which indicated high surface activity. They efficiently emulsified aromatic hydrocarbons, kerosene, n-paraffins and mineral oils. Biosurfactant production contributed to a significant increase in cell hydrophobicity correlated with an increased growth of the strain on hexadecane. The results suggested that the newly isolated strain of Ps. fluorescens and produced glycolipid biosurfactants with effective surface and emulsifying properties are very promising and could find application for bioremediation of hydrocarbon-polluted sites.

Studies suggest that type 2 diabetes mellitus is associated with increased gut permeability. Human zonulin is the only physiological mediator discovered to date that is known to regulate gut permeability reversibly by disassembling intestinal tight junctions. However, the relationship between zonulin and type 2 diabetes remains to be defined, and no Chinese population-based data were reported. The aim of this study was to investigate the association between serum zonulin levels and type 2 diabetes in a Chinese Han population. 143 newly diagnosed type 2 diabetes patients, 124 patients with impaired glucose tolerance and 121 subjects with normal glucose tolerance were enrolled in this study. Serum zonulin was measured by ELISA. Patients with type 2 diabetes had higher serum zonulin levels than impaired or normal glucose tolerant subjects. Serum zonulin correlated with body mass index, waist-to-hip ratio, triglyceride, total cholesterol, HDL-C, fasting plasma glucose, 2h plasma glucose, HbA1c, tumor necrosis factor α, interleukin 6, HOMA-IR and QUICK index using correlation analysis (p zonulin levels were independently associated with insulin resistance (β = 0.024, p = 0.005). In logistic regression analysis, zonulin levels were an independent predictor of type 2 diabetes (OR = 1.080, p = 0.037). Serum zonulin levels are significantly elevated in newly diagnosed Chinese Type 2 diabetes patients, and are associated with dyslipidemia, inflammation and insulin resistance, indicating a potential role of zonulin in the pathophysiology of type 2 diabetes in Chinese.

Sitzenfrei, Robert; Möderl, Michael; Rauch, Wolfgang

2013-09-01

In the field of water distribution system (WDS) analysis, case study research is needed for testing or benchmarking optimisation strategies and newly developed software. However, data availability for the investigation of real cases is limited due to time and cost needed for data collection and model setup. We present a new algorithm that addresses this problem by generating WDSs from GIS using population density, housing density and elevation as input data. We show that the resulting WDSs are comparable to actual systems in terms of network properties and hydraulic performance. For example, comparing the pressure heads for an actual and a generated WDS results in pressure head differences of ±4 m or less for 75% of the supply area. Although elements like valves and pumps are not included, the new methodology can provide water distribution systems of varying levels of complexity (e.g., network layouts, connectivity, etc.) to allow testing design/optimisation algorithms on a large number of networks. The new approach can be used to estimate the construction costs of planned WDSs aimed at addressing population growth or at comparisons of different expansion strategies in growth corridors.

High prevalence of cachexia in newly diagnosed head and neck cancer patients: An exploratory study.

In patients with cancer, weight loss can be related to simple starvation, disturbed metabolism, or both. In patients with head and neck cancer (HNC), weight loss often is attributed to simple starvation because the obvious oral symptoms are known to hinder dietary intake. In this population, cachexia remains a relatively unexplored phenomenon. The aim of this study was to explore the prevalence of cachexia and precachexia in patients with newly diagnosed HNC. Fifty-nine patients with newly diagnosed HNC were asked to participate in the prospective cohort study, from which only baseline data were used in the analyses. Measurements were performed 1 wk before cancer treatment, that is, cachexia status by Fearon's cancer-specific framework, dietary intake, muscle mass, muscle strength, and biochemical markers (C-reactive protein, albumin, hemoglobin, interleukin-1β, interleukin-6, and tumor necrosis factor-α) were assessed. Data of 26 patients were included in the analyses (59% participation rate). Forty-two percent of the patients (n = 12) were classified as cachectic and 15% (n = 4) as precachectic. Muscle mass depletion was significantly more frequent in cachectic patients (67%) than in noncachectic patients (14%; P = 0.014). No differences in inflammatory markers were observed between cachectic and noncachectic patients. This exploratory study suggested a high prevalence of cachexia (42%) in patients with newly diagnosed HNC. Although a large study is needed to further elucidate the role of cachexia in patients with HNC, the data presented here suggest that cachexia is a common problem in this patient population, which has therapeutic and prognostic implications.

Purpose: To examine the usefulness of MR imaging for predicting local control of nasopharyngeal carcinoma (NPC) and the value of MR imaging in the newly published fifth edition of the TNM classification. Methods and Materials: We studied 29 patients with NPC with MR imaging and CT before and after treatment. Staging was done according to the fourth and newly published fifth editions of the International Union Against Cancer (UICC) staging system. The radiotherapy protocol was designed to deliver 66 to 68 Gy to the primary tumor and clinically involved nodes. Results: MR proved better than CT at identifying obliteration of the pharyngobasilar fascia, invasion of the sinus of Morgagni, through which the cartilaginous portion of the eustachian tube and the levator veli palatini muscle pass, invasion of the skull base, and metastases to lymph nodes in the carotid and retropharyngeal spaces. All seven patients without invasion of the pharyngobasilar fascia had local control. The local control rates of patients with invasion of the skull base were not good (60 to 73%). There was no apparent relationship between tumor volume determined by T1-weighted MR images and local control when the tumor volume was more than 20 cc. The newly published N staging system appears to successfully identify the high-risk group for distant metastasis as N3. In our series, four of five patients with N3 disease developed distant metastases. Conclusion: Deep infiltration of the tumor is a more important prognostic factor in NPC than tumor volume. Since the newly published T staging system requires a search for tumor invasion into soft tissue such as parapharyngeal space and bony structures, MR imaging may be indispensable for the newly published NPC staging system

The $16,819 pay gap for newly trained physicians: the unexplained trend of men earning more than women.

Lo Sasso, Anthony T; Richards, Michael R; Chou, Chiu-Fang; Gerber, Susan E

2011-02-01

Prior research has suggested that gender differences in physicians' salaries can be accounted for by the tendency of women to enter primary care fields and work fewer hours. However, in examining starting salaries by gender of physicians leaving residency programs in New York State during 1999-2008, we found a significant gender gap that cannot be explained by specialty choice, practice setting, work hours, or other characteristics. The unexplained trend toward diverging salaries appears to be a recent development that is growing over time. In 2008, male physicians newly trained in New York State made on average $16,819 more than newly trained female physicians, compared to a $3,600 difference in 1999.

Prognostic value of regulatory T cells in newly diagnosed chronic myeloid leukemia patients.

Zahran, Asmaa M; Badrawy, Hosny; Ibrahim, Abeer

2014-08-01

Chronic myeloid leukemia (CML) is a clonal disease, characterized by a reciprocal t(9, 22) that results in a chimeric BCR/ABL fusion gene. Regulatory T cells (Tregs) constitute the main cell population that enables cancer cells to evade immune surveillance. The purpose of our study was to investigate the level of Tregs in newly diagnosed CML patients and to correlate it with the patients' clinical, laboratory and molecular data. We also aimed to assess the effect of treatment using tyrosine kinase inhibitor (TKI) on Treg levels. Tregs were characterized and quantified by flow cytometry in 63 newly diagnosed CML patients and 40 healthy controls. TKI was used in 45 patients with chronic phase CML, and the response to therapy was correlated with baseline Treg levels. The percentages of Tregs were significantly increased in CML patients compared to the controls. Treg numbers were significantly lower in patients with chronic phase CML versus the accelerated and blast phases, and were significantly lower in patients with complete molecular remission (CMR) compared to those patients without CMR. Tregs may play a role in the maintenance of CML. Moreover, the decrease of their levels in patients with CMR suggests that Tregs might have a clinical value in evaluating the effects of therapy.

2018-01-01

Background Newly graduated nurses often encounter a gap between theory and practice in clinical settings. Although this has been the focus of considerable research, little is known about the learning transition process. Purpose The purpose of this study was to explore the experiences of newly graduated nurses in acute healthcare settings within Canada. This study was conducted to gain a greater understanding of the experiences and challenges faced by graduates. Methods Grounded theory method was utilized with a sample of 14 registered nurses who were employed in acute-care settings. Data were collected using in-depth interviews. Constant comparative analysis was used to analyze data. Results Findings revealed a core category, "Theory Becoming Alive," and four supporting categories: Entry into Practice, Immersion, Committing, and Evolving. Theory Becoming Alive described the process of new graduate nurses' clinical learning experiences as well as the challenges that they encountered in clinical settings after graduating. Conclusions This research provides a greater understanding of learning process of new graduate nurses in Canada. It highlights the importance of providing supportive environments to assist new graduate nurses to develop confidence as independent registered nurses in clinical areas. Future research directions as well as supportive educational strategies are described.

Insertion of carmustine wafers into the resection cavity as a treatment for malignant glioma is currently a controversial topic among neurosurgeons. Our meta-analysis focused on whether carmustine wafer treatment could significantly benefit the survival of patients with newly diagnosed glioblastoma multiforme (GBM.Method: We searched the PubMed and Web of Science databases without any restrictions on language using the keywords “Gliadel wafers”, “carmustine wafers”, “BCNU wafers”, or “interstitial chemotherapy” in newly diagnosed GBM for the period from January 1990 to March 2015. Randomized controlled trials (RCTs and cohort studies/clinical trials that compared treatments designed with and without carmustine wafers and which reported overall survival or hazard ratio (HR or survival curves were included in this study. Moreover, the statistical analysis was conducted by the STATA 12.0 software.Results: Six studies including two RCTs and four cohort studies, enrolling a total of 513 patients (223 with and 290 without carmustine wafers, matched the selection criteria. Carmustine wafers showed a strong advantage when pooling all the included studies (HR =0.63, 95% confidence interval (CI =0.49–0.81; P=0.019. However, the two RCTs did not show a statistical increase in survival in the group with carmustine wafer compared to the group without it (HR =0.51, 95% CI =0.18–1.41; P=0.426, while the cohort studies demonstrated a significant survival increase (HR =0.59, 95% CI =0.44–0.79; P<0.0001.Conclusion

Self generation, small generation, and embedded generation issues

International Nuclear Information System (INIS)

2001-01-01

The New Brunswick Market Design Committee for electric power restructuring has been directed to examine issues regarding cogeneration and small-scale, on-site generation and how they will fit within the framework of the bilateral contract market. The Committee will also have to deal with issues of generation embedded in a distribution system. The Committee has defined cogeneration as the simultaneous production of electricity and useful thermal energy. Self-generation has been defined as small-scale power generation by an end-user, while embedded generation has been defined as a generation facility that is located within a distribution utility but is not directly connected to the transmission system. The Committee has postponed its decision on whether embedded generation will be eligible to participate under the bilateral contract market for electricity. This report discusses general issues such as the physical support of generation, market support of generation, transition issues and policy issues. It also discusses generation support issues such as operating reserves, transmission tariff issues, and distribution tariffs. Market support issues such as transmission access for generation sales were also considered, along with market access for generation sales, and net metering for behind the meter generation. 7 refs., 1 tab

Liberalization of power generation sector in the Croatian electricity market

2005-01-01

The electricity market liberalization and the restructuring of power utilities eventually leads to the establishment of a single electricity market in Europe, which is especially important for efficiency gains in electricity generation coupled with increased security of supply, economic competitiveness and fulfillment of environmental requirements. The European electricity market Directives as well as the Energy Community Treaty for South East Europe (legislative Menu) have remarkable impact on the restructuring of the Croatian power sector and the development of electricity generation. The Croatian model of restructuring includes legal un bundling (in the ownership of one holding company - Hrvatska Elektroprivreda (HEP)). The operation of HEP Group and its subsidiaries in the conditions of partially opened electricity market in an important element that shapes the interactions of competitive activities and regulated activities in the environment influenced by exogenous factors a thirteen percent electricity are controlled by the Energy Market Operator (MO), the Transmission System Operator (TSO) and the Energy Regulatory Agency (CERA). The introduction of eligible procedures and newly created operative procedures for power system operation, are creating completely new conditions for competition in the power generation sector, where almost all power plants are owned by HEP. New generating capacities in Croatia can be built through tendering and licensing procedures carried out by the Regulator. Electricity prices are still regulated by the Government (below the cost reflective level), there is a small share of industrial consumers and the annual electricity production is 12 TWh, with relatively large share of hydro plants. All these have implications on the development of the power generation sector in Croatia as well as on electricity market operation. The subject matter of this paper is an impact of power system restructuring and electricity market opening on the

Soil heavy metal contents were measured in newly submerged areas of the Danjiangkou Reservoir, China. We aimed to determine the heavy metal distribution in this area and the associated ecological risk. Most of these heavy metal contents (except Pb and Mn) suggest enrichment compared with the background values of soils from Henan Province, especially As and Cd with mean geo-accumulation index (I geo ) values of 0.84 and 0.54. The spatial analysis results indicated that the highest heavy metal contents were distributed in the arable soils above 160m elevation, whereas low heavy metal contents were observed under other land-use types above 160m elevation. According to I geo and EF values, Cd was the major heavy metal contaminant in the newly submerged area, Cr, Pb and Mn mainly originated from natural geochemical sources. In contrast, Ni, Cd, As, Cu, and Zn mainly originated from anthropogenic sources. Evaluation using the potential ecological risk (PER) method indicated that PER of individual elements were low in the studied soils, and the comprehensive PER index was at a moderate level, indicating heavy metals in the soils of newly submerged areas may not threaten the water quality of Danjiangkou Reservoir, especially in winter.

We investigated the association of thiazolidinedione and its dose effect with the risk of Parkinson's disease (PD) in patients with diabetes mellitus (DM). This study enrolled 38,521 patients with newly-diagnosed DM between 2001 and 2013 and compared them to matched subjects without DM. The hazard ratios (HRs) for PD were compared between the thiazolidinedione-treated and non-thiazolidinedione-treated groups of the study cohort, and between subgroups who received different cumulative dosages of thiazolidinedione. We observed 544 (1.4%) patients with PD during the follow up of median duration of 6.2 years in patients with newly-diagnosed DM who had a higher risk for PD than patients without DM (HR = 1.150). In the study cohort, the risk of PD was significantly lower in the thiazolidinedione-treated group (HR = 0.399) compared to the non-thiazolidinedione-treated group. Thiazolidinedione reduced the risk of PD in a dose-dependent manner, with HRs ranging from 0.613 to 0.081 with defined daily doses of 0-90 to > 720, respectively. Thiazolidinedione use was associated with a significantly reduced risk of PD in patients with newly-diagnosed DM. Further studies to elucidate the common mechanism of PD and DM may provide novel therapies for these two diseases.

Full Text Available Since the majority of network concession contracts in Germany were set to expire some time between 2005 and 2016, a window of opportunity arose in which to rebuild and remunicipalise the local energy supply. As a result, 72 new local power companies were established in Germany within the space of just seven years (between early 2005 and late 2012. This paper provides an introduction to the topic of establishing municipal utilities in Germany. The findings were identified on the basis of the comprehensive screening of all newly established municipal utilities in Germany. Our analysis provides information about regional concentration, the size of municipalities, the legal forms of the newly founded municipal public utilities and the role of strategic partnerships. The key findings are that remunicipalisation is not a question of size and that knowledge gaps may be closed by entering into close strategic partnerships.

Several astronomical observations have shown that the ortho/para ratio (OPR) of H 2 can differ from the expected statistical value of 3 or the local thermodynamic equilibrium (LTE) value at the gas or dust temperature. It is thus important to know the OPR of H 2 newly formed on dust grain surfaces, in order to clarify the dependence of the observed OPR in space on the formation process. Using an experimental setup designed to mimic interstellar medium environments, we measured the OPR of H 2 and D 2 formed on the surface of porous amorphous water ice held at 10 K. We report for the first time the OPR value for newly formed D 2 , consistent with the expected LTE value at the high-temperature limit found by previous theoretical and experimental works on the determination of the OPR upon H 2 formation on surfaces at low temperature.

Full Text Available We report on the frequency doubling of femtosecond laser pulses at 1030 nm center wavelength generated from the fully diode-pumped laser system POLARIS. The newly generated pulses at a center wavelength of 515 nm have a pulse energy of 3 J with a pulse duration of 120 fs. On the basis of initially ultra-high contrast seed pulses we expect a temporal intensity contrast better 10 17 200 ps before the peak of the main pulse. We analyzed the temporal intensity contrast from milliseconds to femtoseconds with a dynamic range covering more than 20 orders of magnitude. The pulses were focussed with a f/2-focussing parabola resulting in a peak intensity exceeding 10 20 W / cm 2 . The peak power and intensity are to the best of our knowledge the highest values for 515 nm-laser-pulses achieved so far.

Being diagnosed with cancer causes major psychological distress, yet the majority of newly diagnosed cancer patients lack psychological support. Internet interventions overcome many barriers for seeking face-to-face support and allow for independence in time and place. We assess efficacy and feasibility of the first web-based stress management intervention (STREAM: STREss-Aktiv-Mindern) for newly diagnosed, German-speaking cancer patients. In a prospective, wait-list controlled trial 120 newly diagnosed cancer patients will be included within 12 weeks of starting anti-cancer treatment and randomized between an immediate (intervention group) or delayed (control group) 8-week, web-based intervention. The intervention consists of eight modules with weekly written feedback by a psychologist ("minimal-contact") based on well-established stress management manuals including downloadable audio-files and exercises. The aim of this study is to evaluate efficacy in terms of improvement in quality of life (FACT-F), as well as decrease in anxiety and depression (HADS), as compared to patients in the wait-list control group. A sample size of 120 patients allows demonstrating a clinically relevant difference of nine points in the FACT score after the intervention (T2) with a two-sided alpha of 0.05 and 80 % power. As this is the first online stress management intervention for German-speaking cancer patients, more descriptive outcomes are equally important to further refine the group of patients with the largest potential for benefit who then will be targeted more specifically in future trials. These descriptive endpoints include: patients' characteristics (type of cancer, type of treatment, socio-demographic factors), dropout rate and dropout reasons, adherence and satisfaction with the program. New technologies open new opportunities: minimal-contact psychological interventions are becoming standard of care in several psychological disorders, where their efficacy is often

Preferences for Learning and Skill Development at Work: Comparison of Two Generations

Mariya Karaivanova

2014-09-01

Full Text Available The changing economic conditions of the current dynamic and insecure labour market make learning a constant preoccupation of the workforce with view of meeting the growing qualification demands. These demands are likely to influence the work preferences of both young people now entering the labour market and older people with established career paths. Research findings suggest that the younger generation exhibits a stronger orientation towards learning and skill development as compared to the older generations. Moreover, studies show that the younger people are more ready to leave the organization when they have better learning opportunities elsewhere. The present study aims at establishing how preferences for learning and skill development in the workplace relate to a number of job and organizational characteristics. Particular focus is placed on the predictive capacity of perceived learning opportunities towards the tendency to leave the organization for either of the two generations. The study addresses work preferences of two generations in the Bulgarian labour market. To this aim, 121 respondents answered a 55-item questionnaire consisting of newly developed scales as well as scales based on or adopted from standardized instruments such as the Extended Delft Measurement Kit (Roe et al., 2000. Contrary to findings from previous research done in countries with different cultural and socio-economic background, the older people in our sample were more eager to learn and more ready to leave their organization in pursuit of better opportunities, as compared to the younger generation. Another noteworthy conclusion is that the preferences for learning and development form different patterns in each of the two age groups and are expressed in a different way for each of the two generations.

Current study was designed to use the newly obtained cellulose from waste flower spikes of Thypa latifolia plant for plasmid DNA adsorption. Cellulose was isolated according to a previously described method including acid and base treatment, and cellulose content was recorded as 17%. T. latifolia cellulose was physicochemically characterized via FT-IR, TGA and SEM techniques. Detailed mechanism of plasmid DNA adsorption by newly isolated cellulose was described using chemical quantum calculations. To check the effect of Cu ++ immobilization on the affinity of cellulose for plasmid DNA, copper ions were immobilized onto T. latifolia cellulose. pUC18 plasmid DNA was used for adsorption studies. Membranes prepared with only T. latifolia cellulose and Cu ++ immobilized T. latifolia cellulose revealed different adsorption ratios as 43.9 and 86.9% respectively. This newly isolated cellulose from waste flower spikes of T. latifolia can be utilized as a suitable carrier for plasmid DNA. Copyright © 2017 Elsevier B.V. All rights reserved.

ATAD2 (ATPase family AAA domain-containing protein 2) is a chromatin regulator harboring an AAA+ ATPase domain and a bromodomain, previously proposed to function as an oncogenic transcription co-factor. Here we suggest that ATAD2 is also required for DNA replication. ATAD2 is co-expressed with genes involved in DNA replication in various cancer types and predominantly expressed in S phase cells where it localized on nascent chromatin (replication sites). Our extensive biochemical and cellular analyses revealed that ATAD2 is recruited to replication sites through a direct interaction with di-acetylated histone H4 at K5 and K12, indicative of newly synthesized histones during replication-coupled chromatin reassembly. Similar to ATAD2-depletion, ectopic expression of ATAD2 mutants that are deficient in binding to these di-acetylation marks resulted in reduced DNA replication and impaired loading of PCNA onto chromatin, suggesting relevance of ATAD2 in DNA replication. Taken together, our data show a novel function of ATAD2 in cancer and for the first time identify a reader of newly synthesized histone di-acetylation-marks during replication.

PERFORMANCE OF NEWLY CONFIGURED SUBMERGED MEMBRANE BIOREACTOR FOR AEROBIC INDUSTRIAL WASTEWATER TREATMENT

Full Text Available The application of membrane to replace secondary clarifier of conventional activated sludge, known as membrane bioreactor, has led to a small footprint size of treatment with excellent effluent quality. The use of MBR eliminates almost all disadvantages encountered in conventional wastewater treatment plant such as low biomass concentration and washout of fine suspended solids. However, fouling remains as a main drawback. To minimize membrane fouling, a new configuration of submerged membrane bioreactor for aerobic industrial wastewater treatment has been developed. For the new configuration, a bed of porous particle is applied to cover the submerged ends-free mounted ultrafiltration membrane. Membrane performance was assessed based on flux productivity and selectivity. By using tapioca wastewater containing high organic matter as feed solution, reasonably high and stable fluxes around 11 l/m2.h were achieved with COD removal efficiency of more than 99%. The fouling analysis also shows that the newly configured ends-free membrane bioreactor exhibits lower irreversible resistance compared with the submerged one. In addition, the performance of pilot scale system, using a membrane module  with 10 m2 effective area and reactor tank with 120 L volume, was also assessed. The flux achieved from the pilot scale system around 8 l/m2.h with COD removal of more than 99%. Hence, this study has demonstrated the feasibility of the newly configured submerged ends-free MBR at larger scale.

The purpose of this study was to evaluate the effectiveness of a newly developed perfused monopolar radiofrequency (RF) probe with an umbrella-shaped array. A perfused umbrella-shaped monopolar RF probe based on a LeVeen electrode (Boston Scientific Corp., Natick, MA, USA) with a 3-cm array diameter was developed. Five different configurations of this electrode were tested: (a) perfusion channel/endhole, (b) perfusion channel/endhole + sideholes, (c) 1 cm insulation removed at the tip, (d) 1 cm insulation removed at the tip + perfusion channel/endhole, and (e) 1 cm insulation removed at the tip + perfusion channel/endhole + sideholes. An unmodified LeVeen electrode served as a reference standard. RF ablations were performed in freshly excised bovine liver using a commercial monopolar RF system with a 200-W generator (RF 3000; Boston Scientific Corp.). Each electrode was tested 10 times applying the vendor's recommended ablation protocol combined with the preinjection of 2 ml 0.9% saline. Volumes and shapes of the lesions were compared. Lesions generated with the original LeVeen electrode showed a mean volume of 12.74 ± 0.52 cm 3 . Removing parts of the insulation led to larger coagulation volumes (22.65 ± 2.12 cm 3 ). Depending on the configuration, saline preinjection resulted in a further increase in coagulation volume (25.22 ± 3.37 to 31.28 ± 2.32 cm 3 ). Besides lesion volume, the shape of the ablation zone was influenced by the configuration of the electrode used. We conclude that saline preinjection in combination with increasing the active tip length of the umbrella-shaped LeVeen RF probe allows the reliable ablation of larger volumes in comparison to the originally configured electrode

The Veterans Health Administration (VHA) has deployed a large number of tablet computers in the last several years. However, little is known about how clinicians may use these devices with a newly planned Web-based electronic health record (EHR), as well as other clinical tools. The objective of this study was to understand the types of use that can be expected of tablet computers versus desktops. Semi-structured interviews were conducted with 24 clinicians at a Veterans Health Administration (VHA) Medical Center. An inductive qualitative analysis resulted in findings organized around recurrent themes of: (1) Barriers, (2) Facilitators, (3) Current Use, (4) Anticipated Use, (5) Patient Interaction, and (6) Connection. Our study generated several recommendations for the use of tablet computers with new health information technology tools being developed. Continuous connectivity for the mobile device is essential to avoid interruptions and clinician frustration. Also, making a physical keyboard available as an option for the tablet was a clear desire from the clinicians. Larger tablets (e.g., regular size iPad as compared to an iPad mini) were preferred. Being able to use secure messaging tools with the tablet computer was another consistent finding. Finally, more simplicity is needed for accessing patient data on mobile devices, while balancing the important need for adequate security. Published by Elsevier B.V.

Health-related and social factors predicting non-reemployment amongst newly unemployed

Full Text Available Abstract Background Many researchers have examined the effect that mental health has on reemployment opportunities amongst the unemployed, but the results are inconclusive. Our aim in this study is to investigate the effects that different aspects of mental and physical health, as well as socio-demographic, social, and economic factors, have on reemployment. Methods A questionnaire was administered to 1,000 and answered by 502 newly registered unemployed Swedes, who were followed for one year using data from the Swedish National Labour Market Board. The differences between those reemployed and those not reemployed was analysed using stepwise logistic regression. Results General mental ill health amongst unemployed individuals measured by the General Health Questionnaire scale was associated with lower levels of reemployment after one year. This effect could not be explained by any of the scales measuring specific aspects of mental disease such as health-related level of function, rate of depression, burnout, or alcohol misuse. Instead being above 45, low control over one’s financial situation, being an immigrant, and visiting a physician during the last three months were better predictors of failure to be reemployed. Conclusion There are theoretical reasons to assume that psychological distress leads to a decreased reemployment rate amongst the unemployed. The results of this study partly endorse this hypothesis empirically, showing that general subjective mental distress decreases the rate of reemployment amongst newly unemployed individuals, although this effect was mediated by social and economic factors. Indicators of psychiatric disease had no significant effect on reemployment. The results of this study lead us to suggest the early introduction of financial counselling, psychological support, and other interventions for groups with lower reemployment rates.

An American Academy of Neurology practice parameter recommends that long-term prophylactic anti-epileptic drugs (AED) should not be routine in patients with newly diagnosed brain tumors. However, prospective multi-center North American data shows that most newly diagnosed glioma patients receive prophylactic AED. We examined our own peri-operative AED practice patterns in newly-diagnosed patients with malignant glioma to determine if we deviate from published guidelines. A retrospective chart review was performed in adult patients with newly diagnosed malignant gliomas undergoing surgery in southern Alberta between January 2003 and December 2005. Demographic information, AED use, seizure incidence, adverse effects, tumor size, and tumor location were recorded. Of 164 eligible patients, 54 (33%) presented with seizures and all received AED. Prophylactic AED were given to 44 patients (27%). Peri-operative seizures (within 1 week) occurred in two patients without (3%) and no patients with seizure prophylaxis. Adverse AED reactions and adverse effects attributable to seizures were both rare. Prophylactic AED were continued >1 week post-op in 30 patients (18%). Patients receiving prophylactic AED were more likely to have had tumors involving the temporal lobe than those who did not (50 vs. 20%; P < 0.01). Patients receiving peri-operative AED prophylaxis were common, had a trend to reduced peri-operative seizures, and had few adverse effects. However, most of these patients were maintained on prophylactic AED continued beyond the first peri-operative week, contradicting published guidelines. Increased awareness of practice guidelines may help modify AED prescription patterns in malignant glioma patients.

Various colored cultivars of ornamental flowers have been bred by hybridization and mutation breeding; however, the generation of blue flowers for major cut flower plants, such as roses, chrysanthemums, and carnations, has not been achieved by conventional breeding or genetic engineering. Most blue-hued flowers contain delphinidin-based anthocyanins; therefore, delphinidin-producing carnation, rose, and chrysanthemum flowers have been generated by overexpression of the gene encoding flavonoid 3',5'-hydroxylase (F3'5'H), the key enzyme for delphinidin biosynthesis. Even so, the flowers are purple/violet rather than blue. To generate true blue flowers, blue pigments, such as polyacylated anthocyanins and metal complexes, must be introduced by metabolic engineering; however, introducing and controlling multiple transgenes in plants are complicated processes. We succeeded in generating blue chrysanthemum flowers by introduction of butterfly pea UDP (uridine diphosphate)-glucose:anthocyanin 3',5'- O -glucosyltransferase gene, in addition to the expression of the Canterbury bells F3'5'H . Newly synthesized 3',5'-diglucosylated delphinidin-based anthocyanins exhibited a violet color under the weakly acidic pH conditions of flower petal juice and showed a blue color only through intermolecular association, termed "copigmentation," with flavone glucosides in planta. Thus, we achieved the development of blue color by a two-step modification of the anthocyanin structure. This simple method is a promising approach to generate blue flowers in various ornamental plants by metabolic engineering.

Based on the analysis of the long-term historical and future technical, socio-economic and institutional dynamics of European electricity supply systems and markets, the SUSTELNET project developed scenarios for future electricity supply systems in EU Member States and Newly Associated States (NAS). These scenarios provide a background for the development of regulatory road maps, which can be used as a tool to map out a regulatory strategy, facilitating the transition of current regulation into a regulatory framework that is required for future sustainable electricity supply systems. This report describes four different scenarios for the future of electricity systems and distributed generation (DG) in Europe in a qualitative manner. Moreover, the methodology used to develop these scenarios is described as well as the impact that disruptive events may have on these scenarios

Roberts, Deborah L.

2011-12-01

This study investigated newly qualified teachers' visions of science learning and teaching. The study also documented their preparation in an elementary science methods course. The research questions were: What educational and professional experiences influenced the instructor's visions of science learning and teaching? What visions of science learning and teaching were promoted in the participants' science methods course? What visions of science learning and teaching did these newly qualified teachers bring with them as they graduated from their teacher preparation program? How did these visions compare with those advocated by reform documents? Data sources included participants' assignments, weekly reflections, and multi-media portfolio finals. Semi-structured interviews provided the emic voice of participants, after graduation but before they had begun to teach. These data were interpreted via a combination of qualitative methodologies. Vignettes described class activities. Assertions supported by excerpts from participants' writings emerged from repeated review of their assignments. A case study of a typical participant characterized weekly reflections and final multi-media portfolio. Four strands of science proficiency articulated in a national reform document provided a framework for interpreting activities, assignments, and interview responses. Prior experiences that influenced design of the methods course included an inquiry-based undergraduate physics course, participation in a reform-based teacher preparation program, undergraduate and graduate inquiry-based science teaching methods courses, participation in a teacher research group, continued connection to the university as a beginning teacher, teaching in diverse Title 1 schools, service as the county and state elementary science specialist, participation in the Carnegie Academy for the Scholarship of Teaching and Learning, service on a National Research Council committee, and experience teaching a

Several astronomical observations have shown that the ortho/para ratio (OPR) of H{sub 2} can differ from the expected statistical value of 3 or the local thermodynamic equilibrium (LTE) value at the gas or dust temperature. It is thus important to know the OPR of H{sub 2} newly formed on dust grain surfaces, in order to clarify the dependence of the observed OPR in space on the formation process. Using an experimental setup designed to mimic interstellar medium environments, we measured the OPR of H{sub 2} and D{sub 2} formed on the surface of porous amorphous water ice held at 10 K. We report for the first time the OPR value for newly formed D{sub 2}, consistent with the expected LTE value at the high-temperature limit found by previous theoretical and experimental works on the determination of the OPR upon H{sub 2} formation on surfaces at low temperature.

To describe temporal trend and characteristics of newly HIV-diagnosed patients in a medical care area in Northwest Spain over the last 10 years. All newly diagnosed patients for HIV-infection from 2004 to 2013 at a reference medical care area in Northwest of Spain were identified. Epidemiological, virological, immunological, and clinical data, as well as HIV genotype and drug resistance information were recorded. A total of 565 newly HIV-diagnosed patients were identified. The number of new cases increased in the last 5 years (66 cases/year). Overall, 53.1% had a median CD4 counts study period was 3.7%, but a decreased to 2.6% was observed in the last 5 years. The most prevalent TDR mutations were: T215 revertants (1.5%), K219QENR (1.2%), for NRTIs; K103N (1.9%), for NNRTIs; L90M (0.3%), for PIs. Overall, 73.2% of patients started antiretroviral treatment and 9.9% of patients died during follow-up. The number of newly HIV diagnosed patients increased since year 2009. There is a high prevalence of late diagnosis (53%) and 33% had an AIDS defining criteria. Interestingly, the most prevalent non-B subtype in our population was F (25.8%). These findings support the need to facilitate the access for HIV testing to reduce the rate of late HIV diagnosis, improve the clinical outcome and prevent HIV transmission. © 2015 Wiley Periodicals, Inc.

2010-07-01

Toyota has been introducing several hybrid vehicles (HV) as a countermeasure to the automobile's concerns, like CO2 reduction, energy security, and emission reduction in urban areas. A next step towards an even more effective solution for these concerns is a plug-in hybrid vehicle (PHV). This vehicle combines the advantages of electric vehicles (EV), which use clean electric energy, and HV, with it's high environmental potential and user- friendliness comparable to conventional vehicles, such as a long cruising range. This paper describes a newly developed plug-in hybrid system and its vehicle performance. This system uses a Li-ion battery with high energy density and has an affordable EV range without sacrificing cabin space. The vehicle achieves a CO2 emission of 59g/km and meets the most stringent emission regulations in the world. The new PHV is a forerunner of the large-scale mass production PHV two years later. PHVs have the potential to become popular as a realistic solution towards sustainable mobility by renewable electricity usage in the future. (orig.)

Full Text Available Abstract Background Levels of knowledge about diabetes mellitus (DM among newly diagnosed diabetics in Bangladesh are unknown. This study assessed the relationship between knowledge and practices among newly diagnosed type 2 DM patients. Methods Newly diagnosed adults with type 2 diabetes (N = 508 were selected from 19 healthcare centers. Patients’ knowledge and self-care practices were assessed via interviewer-administered questionnaires using a cross-sectional design. Knowledge questions were divided into basic and technical sections. Knowledge scores were categorized as poor (mean + 1 SD. Chi square testing and multivariate logistic regression were conducted to examine the relationship between diabetes-related knowledge and self-care practices. Results Approximately 16%, 66%, and 18% of respondents had good, average, and poor (GAP basic knowledge respectively and 10%, 78%, and 12% of respondents had GAP technical knowledge, about DM. About 90% of respondents from both basic and technical GAP did not test their blood glucose regularly; a significant relationship existed between basic knowledge and glucose monitoring. Technical knowledge and foot care were significantly related, though 81% with good technical knowledge and about 70% from average and poor groups did not take care of their feet. Approximately 85%, 71%, and 52% of the GAP technical knowledge groups, consumed betel nuts; a significant relationship existed between technical knowledge and consumption of betel nuts. Around 88%, 92%, and 98% of GAP technical knowledge groups failed to follow dietary advice from a diabetes educator. About 26%, 42%, and 51% of GAP basic and technical sometimes ate meals at a fixed time (p Conclusions Newly diagnosed type 2 diabetics had similar levels of basic and technical knowledge of DM. Health education and motivation should create positive changes in diabetes-control-related self-care practices.

The Chilean abalone or "loco" (Concholepas concholepas, Bruguière 1789) represent the most economically important marine recourse exploited from inner inshore Management and Exploitation Areas for Benthic Resources along the Chilean coast. In this study, newly-hatched larvae of C. concholepas were investigated as a potential model species for marine ecotoxicological studies. The study developed a behavioral standard protocol for assessing the impact that kraft pulp mill effluents after secondary treatment have on C. concholepas larvae. Under controlled laboratory conditions, newly-hatched larvae were exposed to a series of different concentrations of kraft pulp mill effluents with secondary treatment (Pinus spp. and Eucalyptus spp.), potassium dichromate as standard reference toxicant and effluent-free control conditions. Regardless of the type of effluent the results indicated that diluted kraft pulp effluent with secondary treatment had reduced effect on larval survival. Low larval survivals were only recorded when they were exposed to high concentrations of the reference toxicant. This suggests that C. concholepas larval bioassay is a simple method for monitoring the effects of kraft pulp mill effluents with secondary treatment discharged into the sea. The results indicated that dilution of ca. 1% of the effluent with an elemental chlorine free (ECF) secondary treatment is appropriate for achieving low larval mortalities, such as those obtained under control conditions with filtered seawater, and to minimize their impact on early ontogenetic stages of marine invertebrates such as newly-hatched larvae of C. concholepas. The methodological aspects of toxicological testing and behavioral responses described here with newly-hatched larvae of C. concholepas can be used to evaluate in the future the potential effects of other stressful conditions as other pollutants or changes in seawater pH associated with ocean acidification. © 2013 Elsevier Inc.

A newly developed Fe-doped calcium sulfide nanoparticles with magnetic property for cancer hyperthermia

Science.gov (United States)

Wu, Steven Yueh-Hsiu; Tseng, Ching-Li; Lin, Feng-Huei

2010-05-01

In this study, a magnetic iron-doped calcium sulfide (Fe-CaS) nanoparticle was newly developed and studied for the purpose of hyperthermia due to its promising magnetic property, adequate biodegradation rate, and relatively good biocompatibility. Fe-CaS nanoparticles were synthesized by a wet chemical co-precipitation process with heat treatment in a N2 atmosphere, and were subsequently cooled in N2 and exposed to air at a low temperature. The crystal structure of the Fe-CaS nanoparticles was similar to that of the CaS, which was identified by an X-ray diffractometer (XRD). The particle size was less than 40 nm based on a Debye-Scherrer equation and transmission electron microscope (TEM) examination. Magnetic properties obtained from the SQUID magnetometer demonstrated that the synthesized CaS was a diamagnetic property. Once the Fe ions were doped, the synthesized Fe-CaS converted into paramagnetism which showed no hysteresis loop. Having been heated above 600 °C in N2, the Fe-CaS showed a promising magnetic property to produce enough energy to increase the temperature for hyperthermia. 10 mg/ml of the Fe-CaS was able to generate heat to elevate the media temperature over 42.5 °C within 6 min. The area of the hysteresis loop increased with the increasing of the treated temperature, especially at 800 °C for 1 h. This is because more Fe ions replaced Ca ions in the lattice at the higher heat treatment temperature. The heat production was also increasing with the increasing of heat treatment temperature, which resulted in an adequate specific absorption ratio (SAR) value, which was found to be 45.47 W/g at 37 °C under an alternative magnetic field of f = 750 KHz , H = 10 Oe. The in vitro biocompatibility test of the synthesized Fe-CaS nanoparticles examined by the LDH assay showed no cytotoxicity to 3T3 fibroblast. The result of in vitro cell hyperthermia shows that under magnetic field the Fe-CaS nanoparticles were able to generate heat and kill the CT-26 cancer

The study aimed to explore latent profiles of coping in Chinese women newly diagnosed with breast cancer and examine the differences of psychological distress, demographic, and medical characteristics across profiles. Latent profile analysis was used to identify 3 classes of copers based on data from 618 Chinese women newly diagnosed with breast cancer who completed questionnaires assessing their coping strategies and psychological distress. "Adaptive coper," reporting most use of adaptive cognitive coping strategies, behaviors of acceptance and shifting attention, and least use of maladaptive cognitive coping strategies, had the best psychological adjustment. "Negative coper," characterized by most use of maladaptive cognitive coping strategies, least use of adaptive cognitive coping strategies except "putting in perspective," and median levels of medical coping behaviors, had the worst psychological adjustment. "Inconsistent coper," with great use of all cognitive coping strategies, and most behaviors of fighting against the disease, and fewest behaviors of attention shift, had relatively high levels of psychological distress. Younger age, less education, shorter time since diagnosis, widowed, living in rural areas, and undergoing chemotherapy are possible markers for patients with less adaptive coping patterns. Interventions should be developed according to the different coping profiles of patients, and the key group to target is "negative copers," who may benefit from cognitive behavioral approaches that combine emotion, cognition and behavior, which could help them more effectively appraise and cope with stressful events.

Full Text Available Methamphetamine (MA is a new arrival to the Southeastern United States (US. Incidence of HIV is also increasing regionally, but data are limited regarding any association between this trend and MA use. We examined behavioral data from North Carolina (NC residents newly diagnosed with HIV, collected by the Department of Health between 2000-2005.Among 1,460 newly diagnosed HIV-positive young men, an increasing trend was seen from 2000-2005 in MA use (p = 0.01, total n = 20. In bivariate analyses, users of MA had significantly greater odds of reporting other substance use, including alcohol, powder or crack cocaine, marijuana, and methylenedioxymethamphetamine (MDMA, "ecstasy". They were also more likely to have reported sexual activity while traveling outside NC; sex with anonymous partners; and previous HIV testing. In a predictive model, MA use had a negative association with nonwhite race, and strong positive associations with powder cocaine, "ecstasy," or intravenous drug use and being a university student.Similar to trends seen in more urban parts of the US, MA use among newly diagnosed, HIV-positive young men is increasing in NC. These data are among the first to demonstrate this relationship in a region with a burgeoning epidemic of MA use. Opportunities exist for MA-related HIV risk-reduction interventions whenever young men intersect the healthcare system.

The detection of autoantibodies to the TSH-receptor (TRAb) by radio-receptor assays (RRA) is widely requested in clinical practice for the diagnostic work-up of Graves' disease and its differentiation from diffuse thyroid autonomy. Additionally, TRAb measurement can be useful during antithyroid drug treatment of Graves' disease to evaluate the risk of relapse after therapy discontinuation. Nevertheless, some patients affected by Graves' disease are TRAb-negative when 1. generation assay is used. In this study the diagnostic performance of a newly developed 2. generation TRAb assay (TRAK human DYNOtest(R), BRAHMS Diagnostica GmbH, Berlin, Germany) was evaluated in 74 untreated patients affected by Graves' disease, in 53 untreated patients affected by Hashimoto's thyroiditis and in 88 patients affected by euthyroid nodular goiter. It was also compared the new TRAb assay with the 1. generation test (TRAK(R) Assay, BRAHMS Diagnostica GmbH, Berlin, Germany) and anti-thyroperoxidase assay (AbTPO DYNOtest(R), BRAHMS GmbH, Berlin). The 2. generation TRAb assay showed the better diagnostic sensitivity in Graves' disease (97%) with respect to the 1. generation assay (85%) and AbTPO assay (64%). The AbTPO assay was positive in 50 of 53 (94%) patients affected by autoimmune thyroiditis. The 1. and 2. generation TRAb assays were positive in 4 (7%) and 7 (13%) of 53 patients affected by autoimmune thyroiditis, respectively. No patients affected by nodular goiter showed positive 1. and 2. generation TRAb assay while AbTPO levels were positive in 8 of 88 patients (specificity 91%). In conclusion, the 2. generation TRAb assay is clearly more sensitive than the 1. generation test and should be used in clinical practice to minimize the incidence of TRAb-negative Graves' disease. Long term prospective studies are needed to evaluate the prognostic role of 2. generation TRAb assay in Graves' disease. The assay of AbTPO is the best marker for autoimmune thyroiditis but is clearly less

In Egypt, data on the prevalence of chronic diabetic complications, which are essential for the adjustment of policies and practices related to diabetes care, are scarce. Therefore, the aim of this study was to determine the frequency of chronic complications of diabetes; namely neuropathy, diabetic kidney disease (DKD), retinopathy and peripheral arterial disease (PAD) in newly-diagnosed versus known type 2 diabetic patients. This is a cross-sectional study that is based on a previous household survey conducted on a representative sample of the population of Alexandria, Egypt. This study included 506 consecutive subjects with type 2 diabetes; 323 patients with previously known T2DM and 183 patients with newly diagnosed T2DM (discovered during the survey). For each participant, a focused history was taken. Comprehensive clinical examination was done including fundus examination, foot examination and assessment of ankle brachial index. Laboratory tests included HbAlc, lipids profile, serum creatinine and urinary albumin creatinine ratio (UACR). Peripheral neuropathy was detected in 20% of the studied patients; 29.4% of known patients and 3.3% of newly diagnosed patients (pDiabetic kidney disease was detected in 33.2% of the studied patients; 46.1% of known patients and 10.4% of newly diagnosed patients (pDiabetic retinopathy was detected in 34.6% of the studied patients; 48.3% of known patients and 10.4% of newly diagnosed patients (pdiabetes, the presence of any of the studied complications (neuropathy, diabetic kidney disease, retinopathy or PAD) was significantly associated with the presence of all other complications (pdiabetes, the presence of diabetic kidney disease was significantly associated with the presence of retinopathy (pdiabetes at the time of diagnosis. Finally, these results should be considered as a call for action for the health care planners and providers in our region to plan for early screening for diabetes and its complications to reduce the

The objective of this study was to explore the efficacy of low dose of oxcarbazepine (OXC) in adult patients with newly diagnosed partial epilepsy in an actual clinical setting. The associated factors influencing the poor control of seizures were also evaluated. The epilepsy database (2010-2014) from the Epilepsy Clinic of West China Hospital was retrospectively reviewed. A total of 102 adult patients with newly diagnosed, previously untreated partial epilepsy initially treated with OXC were included, and divided into good response group (64) and poor response group (38) according to whether they were seizure-free for at least 12 months. There were 27 (26.5%) patients becoming seizure-free with OXC 600 mg/day monotherapy. The remaining 75 patients had doses of either increasing OXC to 900 mg/day (n = 59) or the addition of another antiepileptic drug (AED) (n = 16), with another 20 (19.6%) and six (5.9%) patients becoming seizure-free, respectively (P = 0.788). In addition, two (2.0%) and nine (8.8%) patients became seizure-free with OXC > 900 mg/day monotherapy and OXC ≥ 900 mg/day combination therapy, respectively. Multivariate binary logistic regression analysis revealed that the time from onset of epilepsy to treatment initiation is significantly associated with seizure control (P = 0.02). Our results indicated that OXC at low to moderate doses is effective for the treatment of Chinese adult patients with newly diagnosed, previously untreated partial epilepsy, and a longer time interval from the onset of epilepsy to the start of treatment significantly predicts poor seizure control.

Of the patients with HbA1c ≥ 7.5% at diagnosis, 87% initiated treatment within 2 years. These patients with a higher HbA1c also had shorter time to treatment initiation (adjusted hazard ratio (HR = 2.44 [95% confidence interval (CI: 1.61, 3.70]; p Conclusions In this UK cohort of patients with newly diagnosed type 2 diabetes, only 51% had antihyperglycaemic medication initiated over a 2-year period following diagnosis. Older patients were significantly less likely to have been prescribed antihyperglycaemic medications. Elevated HbA1c was the strongest factor associated with initiating antihyperglycaemic medication in these patients.

The main focus of this study was to investigate spectroscopic properties, stoichiometric ratios, physicochemical parameters, polarity and photostability behaviors of newly synthesized chalcone dye in organized media. The chalcone dye, 1-(2,5-Dimethyl-thiophen-3-yl)-3-(9-etnyl-9H-carbazol-3-yl)-propenone (DTEP), was prepared by the reaction of carbazole aldehyde with 3-acetyl-2,5-dimethythiophene. Data obtained from FT-IR, 1 H-–NMR, 13 C-NMR and elemental analysis were consistent with chemical structure of newly prepared DTEP. Increases in fluorescence intensities of DTEP with cetyltrimethyl ammonium bromide (CTAB) were observed. In comparison of fluorescence intensities for DTEP with CTAB, reductions in fluorescence intensities for DTEP with sodium dodecyl sulfate (SDS) were noticed under the same experimental and instrumental conditions. Additionally, Benesi–Hildebrand method was applied to determine stoichiometric ratios and association constants of DTEP with CTAB and SDS. Stern–Volmer plot was used in order to further confirm the stoichiometric ratio and association constant of DTEP with SDS. Physicochemical parameters such as singlet absorption, molar absorptivity, oscillator strength, dipole moment and fluorescence quantum yield of DTEP were also determined. Fluorescence polarity study displayed that DTEP was sensitive to the polarity of the microenvironment provided by different solvents. Finally, fluorescence steady-state measurements revealed that DTEP has high photostability against photobleaching. -- Highlights: ► Mechanistic understanding of molecular structure of newly synthesized chalcone dye. ► Exploring spectral behaviors and physicochemical parameters of chalcone dye. ► Determination of stoichiometric ratios and association constants of chalcone dye. ► Determination of fluorescence quantum yield in different solvents. ► High photostability against photobleaching of chalcone dye was observed

Poly (I:C), which is a synthetic double-stranded RNA, have significant toxicity on tumor cells. The immobilization of Poly (I:C) onto nanoparticles is important for the fabrication of targeted delivery systems. In this study, different generations of newly synthesized PAMAM dendron-coated magnetic nanoparticles (DcMNP) which can be targeted to the tumor site under magnetic field were efficiently loaded for the first time with Poly (I:C). Different generations of DcMNPs (G{sub 2}, G{sub 3}, G{sub 4}, G{sub 5}, G{sub 6}, and G{sub 7}) were synthesized. Poly (I:C) activation was achieved in the presence of EDC and 1-methylimidazole. Loading of Poly (I:C) onto DcMNPs was followed by agarose gel electrophoresis. Acidic reaction conditions were found as superior to basic and neutral for binding of Poly (I:C). In addition, having more functional groups at the surface, higher generations (G{sub 7}, G{sub 6}, and G{sub 5}) of PAMAM DcMNPs were found more suitable as a delivery system for Poly (I:C). Further in vitro and in vivo analyses of Poly (I:C)/PAMAM magnetic nanoparticles may provide new opportunities for the selective targeting and killing of tumor cells.

The aim was to investigate the influence of parents' negative mood state and parenting stress on behavior in children with newly diagnosed cancer. A total of 123 parents (n=58 fathers, n=65 mothers) of 67 children with newly diagnosed cancer completed three questionnaires separately at the same time measuring parents' negative mood state, parenting stress, and child behavior problems. Parents' negative mood state was weakly correlated to more child behavior problems (r=0.31, pparenting stress were strongly correlated to more child behavior problems (r=0.61, pparents' negative mood state and child behavior problems (c=0.29, p=0.02 (fathers); c=0.25, p=0.04 (mothers)) became non-significant after mediating for parenting stress (c'=0.003, p=0.98 (fathers); c'=0.10, p=0.42 (mothers)). The indirect effect of parents' negative mood state and child behavior problems was only significant for fathers (95% CI [0.12; 0.51]), indicating that parenting stress mediates the effect between fathers' negative mood state and child behavior problems. This is the first study to demonstrate the mediational role of parenting stress in fathers of a child with newly diagnosed cancer. Copyright © 2014 John Wiley & Sons, Ltd.

To evaluate a novel method for in vitro generation and degradation of neutrophil extracellular traps (NETs), which are a newly recognized structure that is involved in the pathogenesis of autoimmune diseases and thrombosis. Neutrophils from peripheral blood of healthy donors were obtained by Ficoll-Histopaque gradient separation. NET release was initiated by phorbol myristate acetate (PMA) and validated by immunofluorescence staining and agarose gel electrophoresis. NETs degraded by DNase I and healthy human plasma were quantified by fluorescence spectrometry after staining with PicoGreen. HE staining showed that the purity of neutrophils was up to 95% after Ficoll-Histopaque gradient separation. NET immunofluorescent staining revealed that the network structure was mainly composed of DNA and histones, with molecular length more than 10 kb as demonstrated by agarose gel electrophoresis. Moreover, both DNase and healthy human plasma could induce the degradation of NETs, in varying degrees. This work established an efficient method for in vitro generation and degradation of human NETs.

Full Text Available Activated platelets generate an eicosanoid proposed to be 8-hydroxy-9,10-dioxolane A3 (DXA3. Herein, we demonstrate that significant amounts of DXA3 are rapidly attached to phosphatidylethanolamine (PE forming four esterified eicosanoids, 16:0p, 18:0p, 18:1p and 18:0a/DXA3-PEs that can activate neutrophil integrin expression. These lipids comprise the majority of DXA3 generated by platelets, are formed in ng amounts (24.3±6.1 ng/2×108 and remain membrane bound. Pharmacological studies revealed DXA3-PE formation involves cyclooxygenase-1 (COX, protease-activated receptors (PAR 1 and 4, cytosolic phospholipase A2 (cPLA2, phospholipase C and intracellular calcium. They are generated primarily via esterification of newly formed DXA3, but can also be formed in vitro via co-oxidation of PE during COX-1 co-oxidation of arachidonate. All four DXA3-PEs were detected in human clots. Purified platelet DXA3-PE activated neutrophil Mac-1 expression, independently of its hydrolysis to the free eicosanoid. This study demonstrates the structures and cellular synthetic pathway for a family of leukocyte-activating platelet phospholipids generated on acute activation, adding to the growing evidence that enzymatic PE oxidation is a physiological event in innate immune cells.

The aim of this study was to characterize the effects of topiramate on language functions in newly diagnosed pediatric epileptic patients. Thirty-eight newly diagnosed epileptic patients were assessed using standard language tests. Data were collected before and after beginning topiramate during which time a monotherapy treatment regimen was maintained. Language tests included the Test of Language Problem Solving Abilities, a Korean version of the Peabody Picture Vocabulary Test. We used language tests in the Korean version because all the patients were spoken Korean exclusively in their families. All the language parameters of Test of Language Problem Solving Abilities worsened after initiation of topiramate (determine cause, 13.2 ± 4.8 to 11.2 ± 4.3; problem solving, 14.8 ± 6.0 to 12.8 ± 5.0; predicting, 9.8 ± 3.6 to 8.8 ± 4.6). Patients given topiramate exhibited a shortened mean length of utterance in words during response (determine cause, 4.8 ± 0.9 to 4.3 ± 0.7; making inference, 4.5 ± 0.8 to 4.1 ± 1.1; predicting, 5.2 ± 1.0 to 4.7 ± 0.6; P language of patients after taking topiramate (95.4 ± 20.4 to 100.8 ± 19.1). Our data suggest that topiramate may have negative effects on problem-solving abilities in children. We recommend performing language tests should be considered in children being treated with topiramate. Copyright © 2014 Elsevier Inc. All rights reserved.

Our aim was to compare changes in emotional processing by women newly diagnosed with gynecological cancer enrolled in either a coping and communication skills intervention (CCI) or a supportive counseling (SC) intervention. We examined the association between in-session emotional processing and patient-rated therapeutic progress. Three therapy sessions with 201 patients were rated for the depth of emotional processing (peak and mode) during emotion episodes (EEs) using the Experiencing Rating Scale (EXP). Participants completed measures of dispositional emotional expressivity, depressive symptoms, and cancer-related distress before treatment began, as well as ratings of perceived progress in therapy after each session. Peak EXP ratings averaged between 2.7 and 3.1, indicating that women discussed events, their emotional reactions, and their private experiences in sessions. A small proportion of patients had high levels of processing, indicating deeper exploration of the meaning of their feelings and experiences. Women in SC were able to achieve a higher level of emotional processing during the middle and later sessions, and during cancer-related EEs in the later session. However, emotional processing was not significantly associated with a patient's perceived therapeutic progress with SC. In the CCI group, higher levels of emotional processing were associated with greater session progress, suggesting that it may play an important role in patient-rated treatment outcomes. Newly diagnosed gynecological cancer patients are able to attend to their emotions and personal experiences, particularly when discussing cancer-related issues during both short-term SC and prescriptive coping skills interventions.

New faces in new spaces in new places: Residential attainment among newly legalized immigrants in established, new, and minor destinations.

Immigrants at the beginning of the twenty-first century are located in a more diverse set of metropolitan areas than at any point in U.S. Whether immigrants' residential prospects are helped or hindered in new versus established immigrant-receiving areas has been the subject of debate. Using multilevel models and data from the New Immigrant Survey (NIS), a nationally representative sample of newly legalized immigrants to the U.S., we move beyond aggregate-level analyses of residential segregation to specify the influence of destination type on individual-level immigrant residential outcomes. The findings indicate that immigrants in new and minor destinations are significantly more likely to live in tracts with relatively more non-Hispanic whites and relatively fewer immigrants and poor residents. These residential advantages persist net of individual-level controls but are largely accounted for by place-to-place differences in metropolitan composition and structure. Our exclusive focus on newly legalized immigrants means that our findings do not necessarily contradict the possibility of worse residential prospects in new areas of settlement, but rather qualifies it as not extending to the newly authorized population.

Studies evaluating dietary patterns, including the DASH diet, and their relationship with the metabolic syndrome and diabetes may help to understand the role of dairy products (low fat or full fat) in these conditions. Our aim is to identify dietary patterns in Brazilian adults and compare them with the (DASH) diet quality score in terms of their associations with metabolic syndrome and newly diagnosed diabetes in the Brazilian Longitudinal Study of Adult Health-the ELSA-Brasil study. The ELSA-Brasil is a multicenter cohort study comprising 15,105 civil servants, aged 35-74 years at baseline (2008-2010). Standardized interviews and exams were carried out, including an OGTT. We analyzed baseline data for 10,010 subjects. Dietary patterns were derived by principal component analysis. Multivariable logistic regression investigated associations of dietary patterns with metabolic syndrome and newly diagnosed diabetes and multivariable linear regression with components of metabolic syndrome. After controlling for potential confounders, we observed that greater adherence to the Common Brazilian meal pattern (white rice, beans, beer, processed and fresh meats), was associated with higher frequencies of newly diagnosed diabetes, metabolic syndrome and all of its components, except HDL-C. Participants with greater intake of a Common Brazilian fast foods/full fat dairy/milk based desserts pattern presented less newly diagnosed diabetes. An inverse association was also seen between the DASH Diet pattern and the metabolic syndrome, blood pressure and waist circumference. Diet, light foods and beverages/low fat dairy pattern was associated with more prevalence of both outcomes, and higher fasting glucose, HDL-C, waist circumference (among men) and lower blood pressure. Vegetables/fruit dietary pattern did not protect against metabolic syndrome and newly diagnosed diabetes but was associated with lower waist circumference. The inverse associations found for the dietary pattern
