Taking stock of Myanmar’s progress toward the health-related Millennium Development Goals: current roadblocks, paths ahead

Science.gov (United States)

2013-01-01

Myanmar is a developing country with considerable humanitarian needs, rendering its pursuit of the Millennium Development Goals (MDGs) an especially high priority. Yet progress to date remains under-examined on key fronts. Particularly within the three health-related MDGs (MDGs 4, 5, and 6), the limited data reported point to patchy levels of achievement. This study was undertaken to provide an overview and assessment of Myanmar’s progress toward the health-related MDGs, along with possible solutions for accelerating health-related development into 2015 and beyond. The review highlights off-track progress in the spheres of maternal and child health (MDGs 4 and 5). It also shows Myanmar’s achievements toward MDG 6 targets – in the areas of HIV/AIDS, malaria, and tuberculosis. Such achievements are especially notable in that Myanmar has been receiving the lowest level of official development assistance among all of the least developed countries in Asia. However, to make similar progress in MDGs 4 and 5, Myanmar needs increased investment and commitment in health. Toward moving forward with the post-2015 development agenda, Myanmar’s government also needs to take the lead in calling for attention from the World Health Organization and its global development partners to address the stagnation in health-related development progress within the country. In particular, Myanmar’s government should invest greater efforts into health system strengthening to pave the road to universal health coverage. PMID:24025845

Govindaraj, Vijayakumar; Arya, Swathy V; Rao, A J

2014-02-01

Growth of multicellular organisms depends on maintenance of proper balance between proliferation and differentiation. Any disturbance in this balance in animal cells can lead to cancer. Experimental evidence is provided to conclude with special reference to the action of follicle-stimulating hormone (FSH) on Sertoli cells, and luteinizing hormone (LH) on Leydig cells that these hormones exert a differential action on their target cells, i.e., stimulate proliferation when the cells are in an undifferentiated state which is the situation with cancer cells and promote only functional parameters when the cell are fully differentiated. Hormones and growth factors play a key role in cell proliferation, differentiation, and apoptosis. There is a growing body of evidence that various tumors express some hormones at high levels as well as their cognate receptors indicating the possibility of a role in progression of cancer. Hormones such as LH, FSH, and thyroid-stimulating hormone have been reported to stimulate cell proliferation and act as tumor promoter in a variety of hormone-dependent cancers including gonads, lung, thyroid, uterus, breast, prostate, etc. This review summarizes evidence to conclude that these hormones are produced by some cancer tissues to promote their own growth. Also an attempt is made to explain the significance of the differential action of hormones in progression of cancer with special reference to prostate cancer.

Significance of experts' overall ratings for medical student competence in relation to history-taking

Directory of Open Access Journals (Sweden)

Luiz Ernesto de Almeida Troncon

Full Text Available CONTEXT AND OBJECTIVE: Overall ratings (ORs of competence, given by expert physicians, are increasingly used in clinical skills assessments. Nevertheless, the influence of specific components of competence on ORs is incompletely understood. The aim here was to investigate whether ORs for medical student history-taking competence are influenced by performance relating to communication skills, completeness of questioning and asking contentdriven key questions. DESIGN AND SETTING: Descriptive, quantitative study at Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo. METHODS: Thirty-six medical students were examined in a 15-station high-stake objective structured clinical examination (OSCE. At four stations devoted to history-taking, examiners filled out checklists covering the components investigated and independently rated students’ overall performance using a five-point scale from 1 (poor to 5 (excellent. Physician ratings were aggregated for each student. Nonparametric correlations were made between ORs. RESULTS: ORs presented significant correlations with checklist scores (Spearman’s rs = 0.38; p = 0.02 and OSCE general results (rs = 0.52; p < 0.001. Scores for "communication skills" tended to correlate with ORs (rs = 0.31, but without reaching significance (p = 0.06. Neither the scores for "completeness" (rs = 0.26; p = 0.11 nor those for "asking key questions" (rs = 0.07; p = 0.60 correlated with ORs. CONCLUSIONS: Experts’ overall ratings for medical student competence regarding history-taking is likely to encompass a particular dimension, since ratings were only weakly influenced by specific components of performance.

IAEA Mission Sees Significant Progress in Georgia’s Regulatory Framework, Challenges Ahead

International Nuclear Information System (INIS)

2018-01-01

An International Atomic Energy Agency (IAEA) team of experts said Georgia has made significant progress in strengthening its regulatory framework for nuclear and radiation safety. The team also pointed to challenges ahead as Georgia seeks to achieve further progress. The Integrated Regulatory Review Service (IRRS) team concluded a 10-day mission on 28 February to assess the regulatory safety framework in Georgia. The mission was conducted at the request of the Government and hosted by the Agency of Nuclear and Radiation Safety (ANRS), which is responsible for regulatory oversight in the country. IRRS missions are designed to strengthen the effectiveness of the national safety regulatory infrastructure, while recognizing the responsibility of each State to ensure nuclear and radiation safety. Georgia uses radioactive sources in medicine and industry and operates radioactive waste management facilities. It has decommissioned its only research reactor and has no nuclear power plants. In recent years, the Government and ANRS, with assistance from the IAEA, introduced new safety regulations and increased the number of regulatory inspections.

2012-07-01

Set partition coding (SPC) has shown tremendous success in image compression. Despite its popularity, the lack of error resilience remains a significant challenge to the transmission of images in error-prone environments. In this paper, we propose a novel data representation called the progressive significance map (prog-sig-map) for error-resilient SPC. It structures the significance map (sig-map) into two parts: a high-level summation sig-map and a low-level complementary sig-map (comp-sig-map). Such a structured representation of the sig-map allows us to improve its error-resilient property at the price of only a slight sacrifice in compression efficiency. For example, we have found that a fixed-length coding of the comp-sig-map in the prog-sig-map renders 64% of the coded bitstream insensitive to bit errors, compared with 40% with that of the conventional sig-map. Simulation results have shown that the prog-sig-map can achieve highly competitive rate-distortion performance for binary symmetric channels while maintaining low computational complexity. Moreover, we note that prog-sig-map is complementary to existing independent packetization and channel-coding-based error-resilient approaches and readily lends itself to other source coding applications such as distributed video coding.

The SOS response is readily triggered by replication fork stalling caused by DNA damage or a dysfunctional replicative apparatus in Escherichia coli cells. E. coli dinB encodes DinB DNA polymerase and its expression is upregulated during the SOS response. DinB catalyzes translesion DNA synthesis in place of a replicative DNA polymerase III that is stalled at a DNA lesion. We showed previously that DNA replication was suppressed without exogenous DNA damage in cells overproducing DinB. In this report, we confirm that this was due to a dose-dependent inhibition of ongoing replication forks by DinB. Interestingly, the DinB-overproducing cells did not significantly induce the SOS response even though DNA replication was perturbed. RecA protein is activated by forming a nucleoprotein filament with single-stranded DNA, which leads to the onset of the SOS response. In the DinB-overproducing cells, RecA was not activated to induce the SOS response. However, the SOS response was observed after heat-inducible activation in strain recA441 (encoding a temperature-sensitive RecA) and after replication blockage in strain dnaE486 (encoding a temperature-sensitive catalytic subunit of the replicative DNA polymerase III) at a non-permissive temperature when DinB was overproduced in these cells. Furthermore, since catalytically inactive DinB could avoid the SOS response to a DinB-promoted fork block, it is unlikely that overproduced DinB takes control of primer extension and thus limits single-stranded DNA. These observations suggest that DinB possesses a feature that suppresses DNA replication but does not abolish the cell's capacity to induce the SOS response. We conclude that DinB impedes replication fork progression in a way that does not activate RecA, in contrast to obstructive DNA lesions and dysfunctional replication machinery.

Demonstrating the benefits of fuel cells: further significant progress towards commercialisation

Energy Technology Data Exchange (ETDEWEB)

Anon,

1995-01-01

The fourteenth Fuel Cell Seminar held in San Diego, California in 1994 is reported. The phosphoric acid fuel cell (PAFC) is the closest to widespread commercialization. PAFC cogeneration plants have to be shown to compare favourable in reliability with current mature natural gas-fuelled engine and turbine technologies. Although highly efficient, further development is necessary to produce cost effective generators. Progress is being made on proton exchange membrane fuel cell (PEMFC) stationary power plants, too, which may prove to be cost effective. In view of its lower operating temperature, at below 100[sup o]C compared with about 200[sup o]C for the PAFC, the principal use of the PEMFC has been identified as powering vehicles. Fuel cells have significant environmental advantages but further capital cost reductions are necessary if they are to compete with established technologies. (UK)

F-18 FDG-PET is useful for detection and staging of lymphoma. We investigated the prognostic significance of maximum standard uptake (maxSUV) value of FDG-PET for newly diagnosed lymphoma patients before chemotherapy. Twenty-seven patients (male: female = 17: 10: age: 49±19 years) with newly diagnosed lymphoma were enrolled. Nine-teen patients suffered from B cell lymphoma, 6 Hodgkins disease and 2 T cell lymphoma. One patient was stage I, 9 stage II, 3 stage III, 1 stage IV and 13 others. All patients underwent FDG-PET before initiation of chemotherapy. MaxSUV values using lean body weight were obtained for main and largest lesion to represent maxSUV of the patients. The disease progression was defined as total change of the chemotherapeutic regimen or addition of new chemotherapeutic agent during follow up period. The observed period was 389±224 days. The value of maxSUV ranged from 3 to 18 (mean±SD = 10.6±4.4). The disease progressions occurred in 6 patients. Using Cox proportional-hazard regression analysis, maxSUV was identified as a significant parameter for the disease progression free survival (p=0.044). Kaplan-Meier survival curve analysis revealed that the group with higher maxSUV (=10.6, n=5) suffered from shorter disease progression free survival (median 299 days) than the group with lower maxSUV (<10.6, n = 22) (median 378 days, p=0.0146). We found that maxSUV on pre-chemotherapeutic F-18 FDG-PET for newly diagnosed lymphoma patients is a significant parameter for disease progression. Lymphoma patients can be stratified before initiation of chemotherapy in terms of disease progression by the value of maxSUV 10.6

Does significant renal ablation truly and invariably lead to hyperfiltration and progressive chronic kidney disease?

Wang, Andrew; Sam, Ramin

2017-06-01

It is generally believed that significant renal ablation leads to hyperfiltration and eventually progressively worsening chronic kidney disease. The data behind this belief have not been scrutinized intensively. More importantly, the above belief leads many physicians to manage patients differently than they otherwise would manage. Here, we examine the data behind whether hyperfiltration occurs when patients lose kidney mass (by excision or by disease) and whether the hyperfiltration is uniformly injurious.

The Modern Idea of Progress by Jean A. Condorcet

Full Text Available The 18th century is the opening to cognitive progress (epistemology which becomes the core of historical progress. They were defined more precisely by Robert Turgot (1727-1781. Turgot’s lecture entitled Discours sur l´histoire universalle of 1750 significantly contributed to the notion of “progress”. The lecture presented a broad programme of historical studies whose object was humanity striving for perfection. Turgot’s programme was implemented by his friend Jean Antoine de Condorcet (1743-1794. He contained the interpretation of his programme of historical progress in Esquisse d´un tableau historique des progrés de l´esprit humain (A sketch of the picture of progress of human spirit through the ages. It was 1794 and in that year Condorcet was imprisoned. Jean Antoine de Condorcet proposed a secular mechanism of progress which was to take place through development of knowledge and science. In his outline of the development of humanity, Condorcet emphasised that the progress of humanity occurs because of efforts of people without interference of divine factors. Man is able to improve due to his own mind. The history of humanity is presented in his philosophy as a linear, continuous process taking place along a rising line, whereas the description of progress includes both past times and the future. In this way, Condorcet showed the perspective of further development of humanity in the direction of a system consistent with the law of nature and the complete elimination of suffering. This view of Condorcet motivated August Comte (1798-1857 when he built the “first philosophy”, and Claude Adrien Helvétius (1715-1771 and Paul Henry d´Holbach (1723-1789.

To analyze the relationship between intraocular pressure (IOP) and the progression of visual field defects in Japanese primary open-angle glaucoma (POAG) and normal-tension glaucoma (NTG) patients. The subjects of the study were patients undergoing treatment for POAG or NTG who had performed visual field tests at least ten times with a Humphrey field analyzer (Swedish interactive thresholding algorithm standard, C30-2 program). The progression of visual field defects was defined by a significantly negative value of the mean deviation slope at the final visual field test during the follow-up period. The relationships between the progression of visual field defects and IOP, as well as other clinical factors, were retrospectively analyzed. A total of 156 eyes of 156 patients were included in the analysis. Significant progression of visual field defects was observed in 70 eyes of 70 patients (44.9%), while no significant progression was evident in 86 eyes of 86 patients (55.1%). The eyes with visual field defect progression had significantly lower baseline IOP (Pfield defect progression than in eyes without (Pfield defects. In NTG, IOP management should take into account not only achieving the target IOP, but also minimizing the fluctuation of IOP during follow-up period.

Progressive nature of heart failure and systems biology

Directory of Open Access Journals (Sweden)

George E. Louridas

2015-01-01

Full Text Available The progressive nature of heart failure (HF is the predominant cause for the clinical course that the HF syndrome is taking. Systems biology methodology is of the utmost importance to explain and comprehend the built-in mechanisms of adverse clinical progression. Various heart diseases produce myocardial damage with subsequent left ventricular remodeling which is the principal underlying pathophysiological mechanism for the clinical progression of HF. The self-organized positive feedback stabilization mechanisms of left ventricular remodeling, adrenergic stimulation and activation of the renin-angiotensin-aldosterone system and natriuretic peptide systems, are hierarchical adaptive processes. These adaptive processes are responsible for further left ventricular remodeling with subsequent clinical deterioration and for the emergence of clinical phenotypes. These mechanisms are counteracted with angiotensin-converting enzyme inhibitors, angiotensin receptor blockers and β-blockers in an attempt to improve the adverse clinical phenomena of HF progression in a new but clinically worse stabilization level. In this review our intention is to underline the progressive nature of the HF syndrome and to demonstrate the significance of ventricular remodeling and the role of self-organized positive feedback adaptive processes.

Recently, female sports participation has increased, and there is a tendency for women to experience more symptoms and variable presentation after sport-related concussion (SRC). The purpose of this study was to determine whether sex differences exist in time to begin a return-to-play (RTP) progression after an initial SRC. After initial SRC, female athletes (11-20 years old) would take longer to begin an RTP progression compared with age-matched male athletes. Retrospective cohort study. Level 3. A total of 579 participants (365 males [mean age, 15.0 ± 1.7 years], 214 females [mean age, 15.2 ± 1.5 years]), including middle school, high school, and collegiate athletes who participated in various sports and experienced an initial SRC were included and underwent retrospective chart review. The following information was collected: sex, age at injury, sport, history of prior concussion, date of injury, and date of initiation of RTP progression. Participants with a history of more than 1 concussion or injury sustained from non-sport-related activity were excluded. Despite American football having the greatest percentage (49.2%) of sport participation, female athletes took significantly longer to start an RTP progression after an initial SRC (29.1 ± 26.3 days) compared with age-matched male athletes (22.7 ± 18.3 days; P = 0.002). On average, female athletes took approximately 6 days longer to begin an RTP progression compared with age-matched male athletes. This suggests that sex differences exist between athletes, ages 11 to 20 years, with regard to initiation of an RTP progression after SRC. Female athletes may take longer to recover after an SRC, and therefore, may take longer to return to sport. Sex should be considered as part of the clinical decision-making process when determining plan of care for this population. © 2016 The Author(s).

John Woolman and Ethical Progress in Kitcher's Pragmatic Naturalism.

Science.gov (United States)

Barresi, John

2017-01-01

The development of John Woolman’s views on slavery plays an important evidentiary role in Philip Kitcher’s recent book, The ethical project (Kitcher 2011). In this work Kitcher takes what he calls a “pragmatic naturalist” approach to ethics and claims that the discovery of ethical truth plays no role in the emergence of ethical progress. To support his view, he argues that Woolman’s contribution was not due to his discovery of an ethical truth about slavery, not previously known, but due to his sensitivity to slavery and his influence on others, which contributed to collective progressive change in moral norms involving slavery. While not disputing Kitcher’s ethical theory, I argue that personal discoveries of a moral psychological nature made by Woolman served both as insights and motivations for his contribution. Thus, even if there are no such things as independent ethical truths that can be discovered by individuals, a fully naturalistic approach to ethical progress requires that we make room not only for group-level progressive evolution of norms, but also for individual discoveries of a moral psychological nature that can sometimes cause an individual to play a significant initiating role in progressive ethical transitions that occur at a group level.

Measuring and reporting on decommissioning progress

International Nuclear Information System (INIS)

Lange, B.A.

2006-01-01

One of the challenges facing AECL, as well as other organizations charged with the responsibility of decommissioning nuclear facilities, is the means by which to measure and report on decommissioning progress to various audiences which, in some cases, may only have a peripheral knowledge or understanding of the complexities associated with the decommissioning process. The reporting and measurement of decommissioning progress is important for a number of reasons, i.e., It provides a vehicle by which to effectively communicate the nature of the decommissioning process; It ensures that stakeholders and shareholders are provided with a transparent and understandable means for assessing value for money; It provides a means by which to integrate the planning, measurement, and operational aspects of decommissioning One underlying reason behind the challenge of reporting decommissioning progress lies in the fact that decommissioning programs are generally executed over periods of time that far exceed those generally associated with typical design and build projects. For example, a decommissioning program could take decades to complete in which case progress on the order of a few percent in any one year might be typical. However, such progress may appear low compared to that seen with more typical projects that can be completed in a matter of years. As a consequence, AECL undertook to develop a system by which to measure decommissioning progress in a straightforward, meaningful, and understandable fashion. The system is not rigorously objective, and there are subjective aspects that are necessitated by the need to keep the system readily understandable. It is also important to note that while the system is simple in concept, there is, nonetheless, significant effort involved in generating and updating the parameters used as input, and in the actual calculations.

1996-01-01

Development of disposal sites for low-level radioactive waste is a complicated legal, regulatory and public sector process. Development of the low-level radioactive waste disposal facility to support generators in Illinois and Kentucky is well under way. Significant progress has been made to re-engineer the siting development process capitalizing on prior lessons learned and a recommitment from Illinois state leadership assuring the future success of the program. Comparisons of why this new process will succeed are the major focus of this paper. Specific changes in approach from the previous process including changes in the Illinois Management Act (Management Act), creation of the Illinois Low-Level Radioactive Waste Siting Task Group (Task Group), new roles for the Illinois State Geologic Survey and Illinois State Water Survey (Scientific Surveys) and the Illinois Department of Nuclear Safety (IDNS), a new contractor reliance approach and increased confidence on the open-quote science close-quote are the major contrasts between the previous process and the new process currently underway

The developmental progression of age 14 behavioral disinhibition, early age of sexual initiation, and subsequent sexual risk-taking behavior.

Research has demonstrated a consistent relationship between early sexual experience and subsequent sexual risk-taking behaviors. We hypothesized that this relationship is due to a general predisposition toward behavioral disinhibition (BD), and that relationships among BD, early sex, and subsequent risky sexual behavior may be influenced by common genetic influences for males and common environmental influences for females. A prospective sample of 1,512 same-sex adolescent twins (50.2% female) was used. Adolescent BD was measured by clinical symptom counts of conduct disorder, oppositional defiant disorder, and self-reported delinquent behavior (age 14). Age of sexual initiation was defined as first age of consensual oral or penetrative sex (mean age ~17). Adult risky sexual behavior was defined by sexual behaviors under the influence of drugs and alcohol and number of casual sexual partners in the past year (age 24). Multivariate analyses showed evidence for substantial common genetic variance among age 14 BD, age at sexual initiation, and adult risky sexual behavior for males, but not females. There was no significant difference in the degree of common environmental influence on these variables for females compared to males. Notably, age of sexual initiation was not significantly correlated with age 24 risky sexual behavior for females. The relationship between early sex and later risky sex can be better understood through a general liability toward BD, which is influenced primarily by genetic factors for males. The association between age 14 BD and age of sexual initiation was influenced through a combination of genetic and environmental factors for females; however, age of sexual initiation does not appear to be a salient predictor of adult women’s sexual risk-taking behavior. Findings suggest that prevention programs aimed at reducing sexual risk behavior might target youth exhibiting BD by age 14, particularly males. More research is needed on what predicts

Disease Progression in a Patient with Nonalcoholic Steatohepatitis

2008-10-01

Full Text Available Nonalcoholic steatohepatitis (NASH is a severe form of nonalcoholic fatty liver disease (NAFLD. The prevalence and clinical significance of NAFLD/NASH have been increasingly recognized in Western countries but much less known in Asian countries, including Taiwan. Here, we report the case of a 43-year-old man who had abnormal liver tests for 18 years. Retrospective evaluation of his initial clinical, laboratory and histologic findings indicated that the hepatic disorder was compatible with the diagnosis of NASH. Although his liver biochemical tests improved after taking lipid-lowering agents, a liver biopsy 17 years later demonstrated histologic progression of intralobular necroinflammation and perivenular fibrosis. These facts suggest that NASH, albeit mild and slowly progressive, indeed exists in Taiwan. After the control of chronic hepatitis B and C and westernization of the lifestyle in Taiwan, an increasing burden of NAFLD/NASH is anticipated and active prophylactic measures should be implemented.

Full Text Available Colorectal cancer (CRC is the third most common cancer in the world. Oplopanax elatus is widely used in traditional medicine. However, little is known about its pharmacological effects and bioactive compounds. We evaluated the effects of the polyyne-enriched extract from O. elatus (PEO on the progression of colon carcinogenesis in ApcMin/+ mice. In addition, these effects were also investigated in HCT116 and SW480 cells. After PEO oral administration (0.2% diet for 12 weeks, PEO significantly improved body weight changes and reduced the tumor burden and tumor multiplicity compared with the untreated mice. Meanwhile, western blot and immunohistochemistry results showed PEO significantly reduced the expression of β-catenin and cyclinD1 in both small intestine and the colon tissues compared with the untreated mice. In addition, PEO treatment significant decreased the cell viability in both HCT116 and SW480 cell lines. It also decreased the levels of β-catenin, cyclinD1, c-myc and p-GSK-3β in HCT116 and SW480 cells at 25 μM. These results indicate that PEO may have potential value in prevention of colon cancer by down-regulating Wnt-related protein.

Fibrodysplasia ossificans progressive is a rare hereditary connective tissue disease characterized by disseminated soft tissue ossification and congenital abnormality of the extremities. It is genetically inherited as a dominant trait with complete penetrance but variable expression. The onset takes place during childhood and the progressive involvement of the spine and proximal extremities leads to immobilization and articular deformity. We report a case of a 22-year-old male patient with typical symptoms of fibrodysplasia ossificans progressive and discuss the new advances in the diagnosis and pathophysiology. (author)

The tumor progression in head and neck squamous cell carcinoma (HNSCC) is one of the main causes of high mortality of the patients with HNSCC. The tumor progression, particularly the metastasis, is characterized by the changes in the composition, functions and structure of different proteins. We have previously shown that serum of HNSCC patients contains the proteins which regulate various cellular processes—adenylyl cyclase associated protein 1 (CAP1), protein phosphatase 1 B (PPM1B), etc. The levels of CAP1 and PPM1B were determined using the enzyme immunoassay. The results of this study show that CAP1 and PPM1B take a part in the progression of HNSCC. The levels of CAP1 and PPM1B in the tumor and in morphologically normal tissue depended on the prevalence of the tumor process. The CAP1 and PPM1B levels were significantly higher in tumor tissue of the patients with regional metastasis. Our data allow assuming the potential possibility for predicting the outcome of the HNSCC measuring the level of tissue CAP1.

Atypical protein kinase C lambda/iota (aPKC λ/ι) is expressed in several human cancers; however, the correlation between aPKC λ/ι localization and cancer progression in human lung adenocarcinoma (LAC) remains to be clarified. We found that patients with a high level of aPKC λ/ι expression in LAC had significantly shorter overall survival than those with a low level of aPKC λ/ι expression. In addition, localization of aPKC λ/ι in the apical membrane or at the cell-cell contact was associated with both lymphatic invasion and metastasis. The intercellular adhesion molecule, E-cadherin, was decreased in LACs with highly expressed aPKC λ/ι at the invasion site of tumor cells. This result suggested that the expression levels of aPKC λ/ι and E-cadherin reflect the progression of LAC. On double-immunohistochemical analysis, aPKC λ/ι and Lgl2, a protein that interacts with aPKC λ/ι, were co-localized within LACs. Furthermore, we found that Lgl2 bound the aPKC λ/ι-Par6 complex in tumor tissue by immune-cosedimentation analysis. Apical membrane localization of Lgl2 was correlated with lymphatic invasion and lymph node metastasis. These results thus indicate that aPKC λ/ι expression is altered upon the progression of LAC. This is also the first evidence to show aPKC λ/ι overexpression in LAC and demonstrates that aPKC λ/ι localization at the apical membrane or cell-cell contact is associated with lymphatic invasion and metastasis of the tumor.

World progress toward fusion energy

International Nuclear Information System (INIS)

Davies, N.A.

1989-01-01

The author discusses international progress in fusion research during the last three years. Much of the technical progress has been achieved through international collaboration in magnetic fusion research. This progress has stimulated political interest in a multinational effort, aimed at designing and possibly constructing the world's first experimental fusion reactor. This interest was reflected in recent summit-level discussions involving President Mitterand, General Secretary Gorbachev, and President Reagan. Most recently, the European Community (EC), Japan, the United States, and the U.S.S.R. have decided to begin serious preparation for taking the next step toward practical fusion energy. These parties have agreed to begin the design and supporting R and D for an International Thermonuclear Experimental Reactor (ITER) under the auspices of the International Atomic Energy Agency (IAEA). The initiation of this international program to prepare for a fusion test reactor is discussed

2017-01-01

Full Text Available We investigated how mothers’ parenting behaviors and personal characteristics were related to risk-taking by young children. We tested contrasting predictions from evolutionary and social role theories with the former predicting higher risk-taking by boys compared to girls and the latter predicting that mothers would influence children’s gender role development with risk-taking occurring more in children parented with higher levels of harshness (i.e., authoritarian parenting style. In our study, mothers reported their own gender roles and parenting styles as well as their children’s risk-taking and activities related to gender roles. The results were only partially consistent with the two theories, as the amount of risk-taking by sons and daughters did not differ significantly and risk-taking by daughters, but not sons, was positively related to mothers’ use of the authoritarian parenting style and the girls’ engagement in masculine activities. Risk-taking by sons was not predicted by any combination of mother-related variables. Overall, mothers who were higher in femininity used more authoritative and less authoritarian parenting styles. Theoretical implications as well as implications for predicting and reducing children’s risk-taking are discussed.

Atypical squamous cells of undetermined significance (ASC-US) is a broad diagnostic category that could be attributed to human papillomavirus infection (HPV), malignant neoplasia and reactive conditions. We evaluated our institutional experience with ASC-US in women who are positive for high risk HPV (HRHPV+) by the Digene hybrid capture method from 2005-2009 to identify the risk of progression to squamous intraepithelial lesion (SIL) and cervical intraepithelial neoplasia (CIN) in association with age. We reviewed cytologic and follow-up surgical pathology reports for all specimens available. Progression was defined as a diagnosis of at least CINI on follow-up biopsy or resection or SIL on cytology. We identified 2613 cases and follow-up was available in 1839 (70.4%). Of these 74.2% had just one follow-up, 16.2% had a total of 2 follow-ups, 5.3% had a total of 3 follow-ups, and the remaining had as many as 6 follow-ups. Among the 1839 patients, 69.4% were age 30 or younger, 16.0% were between 31 to 40, 9.0% were between 41 to 50, and 5.6% were 51 or older. Among these, 25-30% progressed to dysplasia. The risk of progression varied by age (p=0.04) and was lowest among women between the ages of 41-50. Our findings highlight the importance of continued cytologic follow-up in women with HRHPV+ ASC-US in order to detect progression of disease, although the risk of progression is age dependent.

Genetic determinants of financial risk taking.

Kuhnen, Camelia M; Chiao, Joan Y

Individuals vary in their willingness to take financial risks. Here we show that variants of two genes that regulate dopamine and serotonin neurotransmission and have been previously linked to emotional behavior, anxiety and addiction (5-HTTLPR and DRD4) are significant determinants of risk taking in investment decisions. We find that the 5-HTTLPR s/s allele carriers take 28% less risk than those carrying the s/l or l/l alleles of the gene. DRD4 7-repeat allele carriers take 25% more risk than individuals without the 7-repeat allele. These findings contribute to the emerging literature on the genetic determinants of economic behavior.

Full Text Available Background Long non-coding RNAs (lncRNAs have been reported to modulate cardiovascular diseases, and expression dynamics of lncRNAs in the bloodstream were proposed to be potential biomarkers for clinical diagnosis. However, few cardiovascular diseases-related circulating lncRNAs were identified and their prediction power has not been investigated in depth. Here we report a new circulating lncRNA, atherosclerotic plaque pathogenesis associated transcript (APPAT, and evaluated its role and predicting ability in atherosclerotic development. Methods APPAT was analyzed and screened by high-throughput sequencing, and then detected in vitro and in vivo. Immunofluorescence-fluorescence in situ hybridization (IF-FISH was utilized to explore distribution and subcellular location of APPAT. The expressing alteration of APPAT in samples of healthy and pathological coronary artery was explored further. We also assessed the level of circulating APPAT in blood samples from healthy individuals, and patients with angina pectoris (AP or myocardial infarction (MI. Additionally, we predicted and validated microRNA targets of APPAT, then showed the expression level of a candidate target which was primarily measured in human VSMCs cell line, coronary artery, and blood samples. Lastly, we examined the potential indicating ability of APPAT for the risk of AP or MI. Results APPAT showed significant reduction in ox-LDL treated human VSMCs in vitro. It enriched in contractile VSMCs of artery tunica media and mainly existed in cytoplasm. Significant down-regulation of APPAT was found in coronary artery samples with severe stenosis. More importantly, we observed decreased expression of APPAT in blood samples accompanying disease progression. ROC and correlation analyses further verified the relatively high predicting ability of APPAT. We also observed the predicted miRNA exhibited opposite expression direction to that of APPAT. Conclusions This study revealed that

Toward a Progress Indicator for Machine Learning Model Building and Data Mining Algorithm Execution: A Position Paper

Science.gov (United States)

Luo, Gang

2017-01-01

For user-friendliness, many software systems offer progress indicators for long-duration tasks. A typical progress indicator continuously estimates the remaining task execution time as well as the portion of the task that has been finished. Building a machine learning model often takes a long time, but no existing machine learning software supplies a non-trivial progress indicator. Similarly, running a data mining algorithm often takes a long time, but no existing data mining software provides a nontrivial progress indicator. In this article, we consider the problem of offering progress indicators for machine learning model building and data mining algorithm execution. We discuss the goals and challenges intrinsic to this problem. Then we describe an initial framework for implementing such progress indicators and two advanced, potential uses of them, with the goal of inspiring future research on this topic. PMID:29177022

QR-32 is a regressive murine fibrosarcoma cell clone which cannot grow when they are transplanted in mice; QRsP-11 is a progressive malignant tumor cell clone derived from QR-32 which shows strong tumorigenicity. A recent study showed there to be differentially expressed up-regulated and down-regulated proteins in these cells, which were identified by proteomic differential display analyses by using two-dimensional gel electrophoresis and mass spectrometry. Cofilins are small proteins of less than 20 kDa. Their function is the regulation of actin assembly. Cofilin-1 is a small ubiquitous protein, and regulates actin dynamics by means of binding to actin filaments. Cofilin-1 plays roles in cell migration, proliferation and phagocytosis. Cofilin-2 is also a small protein, but it is mainly expressed in skeletal and cardiac muscles. There are many reports showing the positive correlation between the level of cofilin-1 and cancer progression. We have also reported an increased expression of cofilin-1 in pancreatic cancer tissues compared to adjacent paired normal tissues. On the other hand, cofilin-2 was significantly less expressed in pancreatic cancer tissues. Therefore, the present study investigated the comparison of the levels of cofilin-1 and cofilin-2 in regressive QR-32 and progressive QRsP-11cells by western blotting. Cofilin-2 was significantly up-regulated in QRsP-11 compared to QR-32 cells (p<0.001). On the other hand, the difference of the intensities of the bands of cofilin-1 (18 kDa) in QR-32 and QRsP-11 was not significant. However, bands of 27 kDa showed a quite different intensity between QR-32 and QRsP-11, with much higher intensities in QRsP-11 compared to QR-32 (p<0.001). These results suggested that the 27-kDa protein recognized by the antibody against cofilin-1 is a possible biomarker for progressive tumor cells.

2017-09-01

Full Text Available Orientation: The study focused on examining the perceptions of dual-career couples at a stateowned company about the influence of taking maternity and paternity leave on the career progression of black African women in middle management and leadership occupations. Research purpose: The primary purpose of the study was to identify core barriers in relation to maternity and paternity leave that contribute negatively in the career progression of black African women in dual-career couples. Motivation for the study: To obtain insight into the underrepresentation and progression of black African women within dual-career couples, in middle management and leadership occupations. Research design, approach and method: This study was qualitative, comprising a sample of 10 black African women and 10 black African men, with data collected through in-depth semistructured interviews. Thematic analysis was utilised to analyse the interview dialogues. Main findings: The findings established that taking maternity leave has a negative influence on the career progression of black African women in dual-career couples at the state-owned company. The participants further confirmed that involuntary time off work and productiveness were principal influencing barriers of taking maternity leave, leading to other undesirable consequences, such as unproductiveness and reliability. Practical and managerial implications: The state-owned company should review its current talent management and recruitment and selection policies, in order to positively contribute to increasing the representation and facilitating career progression of black African women within dual-career couples, in middle management and leadership occupations. Contributions or value-add: Insights were provided on the influences of taking maternity and paternity leave in the underrepresentation and progression of black African women within dual-career couples, in middle management and leadership occupations.

Progress: Its Glories and Pitfalls.

Science.gov (United States)

Callahan, Daniel

2018-03-01

Steven Pinker, a cognitive psychologist and linguist at Harvard and a savant of big ideas, is one of the latest to take on the idea of progress. He does it under the aegis of "enlightenment," which comes down to a kind of holy trinity of reason, science, and humanism. His new book, Enlightenment Now: The Case for Reason, Science, Humanism, and Progress, is ambitious and cantankerous and heady with hope. On the whole, Pinker makes a good case for the benefits of progress, but with an overdose of feel-good prose. His greatest failure comes in exaggerating the threats to science and in avoiding some problems altogether. He ignores its complexity, its shadows, its creation of new problems raised by its solutions to old ones. Pinker has a particular animus against bioethics, and he misses what has been, I would argue, at the heart of bioethics from its beginning fifty or so years ago. Bioethics was prompted by a new class of medical dilemmas that require a difficult balancing of harms and benefits. Most of them are still with us, and most of them are the result of the progress of postwar medical research and fast-changing clinical practices. © 2018 The Hastings Center.

Progress test utopia.

van der Vleuten, Cees; Freeman, Adrian; Collares, Carlos Fernando

2018-04-01

This paper discusses the advantages of progress testing. A utopia is described where medical schools would work together to develop and administer progress testing. This would lead to a significant reduction of cost, an increase in the quality of measurement and phenomenal feedback to learner and school. Progress testing would also provide more freedom and resources for more creative in-school assessment. It would be an educationally attractive alternative for the creation of cognitive licensing exams. A utopia is always far away in the future, but by formulating a vision for that future we may engage in discussions on how to get there.

Feeling bad about progress does not lead people want to change their health behaviour.

2018-02-01

When do people decide to do something about problematic health behaviours? Theoretical models and pragmatic considerations suggest that people should take action when they feel bad about their progress - in other words, when they experience negative progress-related affect. However, the impact of progress-related affect on goal striving has rarely been investigated. Study 1 (N = 744) adopted a cross-sectional design and examined the extent to which measures of progress-related affect were correlated with intentions to take action. Study 2 (N = 409) investigated the impact of manipulating progress-related affect on intentions and behaviour in an experimental design. Study 1 found that, while engaging in health behaviours had the expected affective consequences (e.g. people felt bad when they were not eating healthily, exercising regularly or limiting their alcohol consumption), it was feeling good rather than bad about progress that was associated with stronger intentions. Study 2 replicated these findings. Participants induced to feel good about their eating behaviour had marginally stronger intentions to eat healthily than participants led to feel bad about their eating behaviour. The findings have implications for interventions designed to promote changes in health behaviour, as well as theoretical frameworks for understanding self-regulation.

Significance of Selective Predation and Development of Prey Protection Measures for Juvenile Salmonids in the Columbia and Snake River Reservoirs: Annual Progress Report, February 1991-February 1992.

Poe, Thomas P.

1992-12-31

This document is the 1991 annual report of progress for the Bonneville Power Administration (BPA) research Project conducted by the US Fish and Wildlife Service (FWS). Our approach was to present the progress achieved during 1991 in a series of separate reports for each major project task. Each report is prepared in the format of a scientific paper and is able to stand alone, whatever the state of progress or completion. This project has two major goals. One is to understand the significance of selective predation and prey vulnerability by determining if substandard juvenile salmonids (dead, injured, stressed, diseased, or naive) are more vulnerable to predation by northern squawfish, than standard or normal juvenile salmonids. The second goal is to develop and test prey protection measures to control predation on juvenile salmonids by reducing predator-smolt encounters or predator capture efficiency.

'This report summarizes the first year''s progress of research funded under the Department of Energy''s Environmental Management Science Program. The research was initiated to better determine ecological risks from toxic and radioactive contaminants. More precisely, the research is designed to determine the relevancy of sublethal cellular damage to the performance of individuals and to identify characteristics of non-human populations exposed to chronic, low-level radiation, as is typically found on many DOE sites. The authors propose to establish a protocol to assess risks to non-human species at higher levels of biological organization by relating molecular damage to more relevant responses that reflect population health. They think that they can achieve this by coupling changes in metabolic rates and energy allocation patterns to meaningful population response variables, and by using novel biological dosimeters in controlled, manipulative dose/effects experiments. They believe that a scientifically defensible endpoint for measuring ecological risks can only be determined once its understood the extent to which molecular damage from contaminant exposure is detrimental at the individual and population levels of biological organization.'

Full Text Available Since the elderly population is increasing rapidly in developing countries which may decrease the physical activity and exercise and in turn could affect the elderly’s quality of life, this study aimed to investigate the effect of progressive muscle relaxation on the elderly’s quality of life in Iran. In a randomized clinical trial, participants were randomly divided into intervention and control groups. For the intervention group, muscular progressive relaxation was run three days per week for three months (totally 36 sessions. In relaxation, a patient contract a group of his/her muscles in each step and relaxes them after five seconds and finally loosens all muscles and takes five deep breaths. Each session lasts for 45 minutes. The instrument of data gathering consisted of questionnaires on individual’s demographic data and quality of life SF-36. After intervention, quality of life increased significantly in the patients undergoing muscular progressive relaxation and fatigue severity decreased significantly in the intervention group compared to prior to intervention. In addition, there was a statistically significant difference in mean score of physical performance, restricted activity after physical problem, energy, socially function, physical pain, overall hygiene, and quality of life between intervention and control groups. By implementing regular and continuous progressive muscle relaxation, quality of life could be increased in different dimensions in the elderly and the context could be provided to age healthily and enjoy higher health and autonomy. Therefore, all of the therapeutic staffs are recommended to implement this plan to promote the elderly’s quality of life.

The disease take-all, caused by the fungus Gaeumannomyces graminis, is one of the most destructive root diseases of wheat worldwide. Breeding resistant cultivars is an effective way to protect wheat from take-all. However, little progress has been made in improving the disease resistance level in commercial wheat cultivars. MYB transcription factors play important roles in plant responses to environmental stresses. In this study, an R2R3-MYB gene in Thinopyrum intermedium, TiMYB2R-1, was cloned and characterized. The gene sequence includes two exons and an intron. The expression of TiMYB2R-1 was significantly induced following G. graminis infection. An in vitro DNA binding assay proved that TiMYB2R-1 protein could bind to the MYB-binding site cis-element ACI. Subcellular localization assays revealed that TiMYB2R-1 was localized in the nucleus. TiMYB2R-1 transgenic wheat plants were generated, characterized molecularly, and evaluated for take-all resistance. PCR and Southern blot analyses confirmed that TiMYB2R-1 was integrated into the genomes of three independent transgenic wheat lines by distinct patterns and the transgene was heritable. Reverse transcription-PCR and western blot analyses revealed that TiMYB2R-1 was highly expressed in the transgenic wheat lines. Based on disease response assessments for three successive generations, the significantly enhanced resistance to take-all was observed in the three TiMYB2R-1-overexpressing transgenic wheat lines. Furthermore, the transcript levels of at least six wheat defence-related genes were significantly elevated in the TiMYB2R-1 transgenic wheat lines. These results suggest that engineering and overexpression of TiMYB2R-1 may be used for improving take-all resistance of wheat and other cereal crops.

Full Text Available It is well-known that physical activity has an anabolic effect on the bone tissue. To examine the influence of the take-off lower limb to the bone density we studied a group of prepubertal boys and girls at the initial phase of their peak bone mass acquisition. A sample consisted of 60 subjects ie., 32 soccer players (boys, 10.7±0.5 years old and 28 swimmers (15 girls and 13 boys, 10.8±0.8 years old, who had performed at least one year of high-level sport training (10-15 hours per week for soccer players, 8-12 hours per week for swimmers. The sample was divided into two groups: the first consisted of 40 subjects, with the left take-off leg, while the second consisted of 20 subjects, with the right take-off leg. The bone mineral density (BMD measurements of the left and the right calcaneus were performed using ultrasound densitometer “Sahara” (Hologic, Inc., MA, USA. There were no significant differences between the groups in regard to BUA and SOS of both the left and the right take-off lower legs. Mean BUA of the take-off left leg and the take-off right leg were different, but not significantly (p>0.05. Likewise, mean SOS of the take-off left leg and the take-off right leg were different, but it was not significant (p>0.05. The results do not indicate that the take-off lower limb has an influence on calcaneal bone mineral density.

Peer-Assisted History-Taking Groups: A Subjective Assessment of their Impact Upon Medical Students' Interview Skills

Directory of Open Access Journals (Sweden)

Keifenheim, Katharina Eva

2017-08-01

Full Text Available Background and Objectives: Among the clinical skills needed by all physicians, history taking is one of the most important. The teaching model for peer-assisted history-taking groups investigated in the present study consists of small-group courses in which students practice conducting medical interviews with real patients. The purpose of this pilot study was to investigate the expectations, experiences, and subjective learning progress of participants in peer-assisted history-taking groups.Methods: The 42 medical student participants completed a 4-month, peer-assisted, elective history-taking course, which both began and ended with a subjective assessment of their interview skills by way of a pseudonymized questionnaire. Measures comprised the students’ self-assessment of their interview skills, their expectations of, and their experiences with the course and especially with the peer tutors. Results: Medical students’ most important motivations in attending peer-assisted history-taking groups were becoming able to complete a structured medical interview, to mitigate difficult interviewing situations, and to address patients’ emotional demands appropriately. By the end of the course, students’ self-assessment of both their interview skills and management of emotional issues improved significantly. Students especially benefitted from individual feedback regarding interview style and relationship formation, as well as generally accepted and had their expectations met by peer tutors. Conclusions: To meet the important learning objectives of history-taking and management of emotional issues, as well as self-reflection and reflection of student–patient interactions, students in the field greatly appreciate practicing medical interviewing in small, peer-assisted groups with real patients. At the same time, peer tutors are experienced to be helpful and supportive and can help students to overcome inhibitions in making contact with patients.

2009-01-01

The progression of tuberculosis from a latent, sub-clinical infection to active disease that culminates in transmission of infectious bacilli is determined locally at the level of the granuloma. This progression takes place even in the face of a robust immune response that, while it contains infection, is unable to eliminate the bacterium. The factors or environmental conditions that influence this progression remain to be determined. Recent advances have indicated that pathogen-induced dysregulation of host lipid synthesis and sequestration plays a critical role in this transition. The foamy macrophage appears to be a key player in both sustaining persistent bacteria and contributing to the tissue pathology that leads to cavitation and release of infectious bacilli.

SIGNIFICANT PROGRESS IN THE DEPLOYMENT OF NEW TECHNOLOGIES FOR THE RETRIEVAL OF HANFORD RADIOACTIVE WASTE STORAGE TANKS

International Nuclear Information System (INIS)

RAYMOND RE; DODD RA; CARPENTER KE; STURGES MH

2008-01-01

Significant enhancements in the development and deployment of new technologies for removing waste from storage tanks at the Hanford Site have resulted in accelerated progress and reduced costs for tank cleanup. CH2M HILL Hanford Group, Inc. is the U.S. Department of Energy, Office of River Protection's prime contractor responsible for safely storing and retrieving approximately 53 million gallons of highly-radioactive and hazardous waste stored in 177 underground tanks. The waste is stored in 149 older single-shell tanks (SST) and 28 newer double-shell tanks (DST) that are grouped in 18 so-called farms near the center of the Hanford Site, located in southeastern Washington State. Tank contents include materials from years of World-War II and post-war weapons production, which account for 60 percent by volume of the nation's high-level radioactive waste. A key strategy for improved cleanup is the development and deployment of innovative technologies, which enhance worker safety, resolve technical challenges, streamline retrieval processes, and cut project costs and durations. During the past seven years of tank cleanout projects we have encountered conditions and waste chemistry that defy conventional approaches, requiring a variety of new tools and techniques. Through the deployment of advanced technology and the creative application of resources, we are finding ways to accomplish the retrieval process safely, swiftly, and economically. To date, retrieval operations have been completed in seven tanks, including a record six tanks in a two-year period. Retrieval operations are in progress for another three tanks. This paper describes the following tank cleanup technologies deployed at Hanford in the past few years: Modified waste sluicing, High pressure water lance, Mobile retrieval tools, Saltcake dissolution, Vacuum retrieval, Sparging of wastes, Selective dissolution for waste treatment, Oxalic acid dissolution, High-pressure water mixers, Variable height pumps

The effects of environmental regulation and technical progress on CO2 Kuznets curve: An evidence from China

International Nuclear Information System (INIS)

Yin, Jianhua; Zheng, Mingzheng; Chen, Jian

2015-01-01

Based on environmental Kuznets curve theory, a panel data model which takes environmental regulation and technical progress as its moderating factors was developed to analyse the institutional and technical factors that affect the path of low-carbon economic development. The results indicated that there was a CO 2 emission Kuznets curve seen in China. Environmental regulation had a significant moderating effect on the curve, and the inflection of CO 2 emissions could come substantially earlier under stricter environmental regulation. Meanwhile, the impact of technical progress on the low-carbon economic development path had a longer hysteresis effect but restrained CO 2 emission during its increasing stage and accelerated its downward trend during the decreasing stage which was conducive to emission reduction. Strict environmental regulation could force the high-carbon emitting industries to transfer from the eastern regions to the central or the western regions of China, which would make the CO 2 Kuznets curve higher in its increasing stage and lower in its decreasing stage than that under looser regulation. Furthermore, energy efficiency, energy structure, and industrial structure exerted a significant direct impact on CO 2 emissions; we should consider the above factors as essential in the quest for low-carbon economic development. - Highlights: • Estimate moderating effect of environmental regulation and technical progress on EKC. • There was a CO 2 emission Kuznets curve in effect in China. • Environmental regulation presents significant moderating effect on EKC. • Technical progress moderates the relationship between income and CO 2 emissions

A word from the DG - Major progress for the LHC

CERN Multimedia

2006-01-01

The return to work after the summer holiday period has been marked by significant progress in the installation of the LHC machine and its detectors. At the beginning of the month, the one thousandth superconducting magnet was positioned in the accelerator tunnel. Passing this symbolic milestone is a testament to the successful efforts of the hundreds of LHC collaborators who are working day and night to install the machine in time, and I would like to take this opportunity to congratulate them. Despite the significant technical and organisational difficulties associated with different types of activities being carried out in parallel in a tunnel where space is limited, the LHC installation teams have achieved remarkable feats. As a result, the delays incurred owing to the problems encountered with the cryogenic distribution line in 2004 have been partly recouped. The cryoline is almost complete, with seven out of eight sectors accepted while installation of the eighth is expected to be completed at the...

Due to rapid urbanization, industrialization and motorization, a large number of Chinese cities are affected by heavy air pollution. In order to explore progress, remaining challenges, and sustainability of air pollution control in the Beijing-Tianjin-Hebei (BTH) region after 2013, a mixed method analysis was undertaken. The quantitative analysis comprised an overview of air quality management in the BTH region. Semi-structured expert interviews were conducted with 12 stakeholders from various levels of government and research institutions who played substantial roles either in decision-making or in research and advising on air pollution control in the BTH region. The results indicated that with the stringent air pollution control policies, the air quality in BTH meets the targets of the Air Pollution Prevention and Control Action Plan. However, improvements vary across the region and for different pollutants. Although implementation has been decisive and was at least in parts effectively enforced, significant challenges remained with regard to industrial and traffic emission control, and national air quality limits continued to be significantly exceeded and competing development interests remained mainly unsolved. There were also concerns about the sustainability of the current air pollution control measures especially for industries due to the top-down enforcement, and the associated large burden of social cost including unemployment and social inequity resulting industrial restructuring. Better mechanisms for ensuring cross-sectoral coordination and for improved central-local government communication were suggested. Further suggestions were provided to improve the conceptual design and effective implementation of respective air pollution control strategies in BTH. Our study highlights some of the major hurdles that need to be addressed to succeed with a comprehensive air pollution control management for the Chinese mega-urban agglomerations. PMID:29425189

Progression of motor symptoms in Parkinson's disease

Institute of Scientific and Technical Information of China (English)

Ruiping Xia; Zhi-Hong Mao

2012-01-01

Parkinson's disease (PD) is a chronic progressive neurodegenerative disease that is clinically manifested by a triad of cardinal motor symptoms - rigidity,bradykinesia and tremor - due to loss of dopaminergic neurons.The motor symptoms of PD become progressively worse as the disease advances.PD is also a heterogeneous disease since rigidity and bradykinesia are the major complaints in some patients whereas tremor is predominant in others.In recent years,many studies have investigated the progression of the hallmark symptoms over time,and the cardinal motor symptoms have different rates of progression,with the disease usually progressing faster in patients with rigidity and bradykinesia than in those with predominant tremor.The current treatment regime of dopamine-replacement therapy improves motor symptoms and alleviates disability.Increasing the dosage of dopaminergic medication is commonly used to combat the worsenirtg symptoms.However,the drug-induced involuntary body movements and motor comphcations can significantly contribute to overall disability.Further,none of the currently-available therapies can slow or halt the disease progression.Significant research efforts have been directed towards developing neuroprotective or disease-modifying agents that are intended to slow the progression.In this article,the most recent clinical studies investigating disease progression and current progress on the development of disease-modifying drug trials are reviewed.

Full Text Available This paper outlines an attempt to discover students’ progress in both content and language skill in a content and language integrated learning (CLIL lessons at an Indonesia’s higher education context. This is a part of a research conducted at Faculty of Science and Technology of Nusa Cendana University in Kupang, East Nusa Tenggara Province. This study employs mixed method approach with 20 participants attending by taking pre-test and post-test as well as joining a focus group interview particularly for 6 students. The tests were aimed at measuring the participants’ comprehension of English as the language of CLIL lesson. They were also used as the tool to evaluate students’ mastery of Mathematics as the content subject. Based on the post-test results, the findings showed that more students made significant progress in content subject in comparison to their achievement in language proficiency. Regarding the interview, the students admitted that their failure to made progress in both subjects were mainly caused by their inadequate level of English. This, therefore, led to rising anxiety among the students to complete the tests.

Adult Neurogenesis in the Mammalian Brain: Significant Answers and Significant Questions

Science.gov (United States)

Ming, Guo-li; Song, Hongjun

2011-01-01

Summary Adult neurogenesis, a process of generating functional neurons from adult neural precursors, occurs throughout life in restricted brain regions in mammals. The past decade has witnessed tremendous progress in addressing questions related to almost every aspect of adult neurogenesis in the mammalian brain. Here we review major advances in our understanding of adult mammalian neurogenesis in the dentate gyrus of the hippocampus and from the subventricular zone of the lateral ventricle, the rostral migratory stream to the olfactory bulb. We highlight emerging principles that have significant implications for stem cell biology, developmental neurobiology, neural plasticity, and disease mechanisms. We also discuss remaining questions related to adult neural stem cells and their niches, underlying regulatory mechanisms and potential functions of newborn neurons in the adult brain. Building upon the recent progress and aided by new technologies, the adult neurogenesis field is poised to leap forward in the next decade. PMID:21609825

Discovery of CDH23 as a Significant Contributor to Progressive Postlingual Sensorineural Hearing Loss in Koreans.

Directory of Open Access Journals (Sweden)

Bong Jik Kim

Full Text Available CDH23 mutations have mostly been associated with prelingual severe-to-profound sensorineural hearing loss (SNHL in either syndromic or nonsyndromic SNHL (DFNB12. Herein, we demonstrate the contribution of CDH23 mutations to postlingual nonsyndromic SNHL (NS-SNHL. We screened 32 Korean adult probands with postlingual NS-SNHL sporadically or in autosomal recessive fashion using targeted panel or whole exome sequencing. We identified four (12.5%, 4/32 potential postlingual DFNB12 families that segregated the recessive CDH23 variants, qualifying for our criteria along with rapidly progressive SNHL. Three of the four families carried one definite pathogenic CDH23 variant previously known as the prelingual DFNB12 variant in a trans configuration with rare CDH23 variants. To determine the contribution of rare CDH23 variants to the postlingual NS-SNHL, we checked the minor allele frequency (MAF of CDH23 variants detected from our postlingual NS-SNHL cohort and prelingual NS-SNHL cohort, among the 2040 normal control chromosomes. The allele frequency of these CDH23 variants in our postlingual cohort was 12.5%, which was significantly higher than that of the 2040 control chromosomes (5.53%, confirming the contribution of these rare CDH23 variants to postlingual NS-SNHL. Furthermore, MAF of rare CDH23 variants from the postlingual NS-SNHL group was significantly higher than that from the prelingual NS-SNHL group. This study demonstrates an important contribution of CDH23 mutations to poslingual NS-SNHL and shows that the phenotypic spectrum of DFNB12 can be broadened even into the presbycusis, depending on the pathogenic potential of variants. We also propose that pathogenic potential of CDH23 variants and the clinical fate of DFNB12 may be predicted by MAF.

The research progress of dual-modality probes for molecular imaging

International Nuclear Information System (INIS)

2010-01-01

Various imaging modalities have been exploited to investigate the anatomic or functional dissemination of tissues in the body. However, no single imaging modality allows overall structural, functional, and molecular information as each imaging modality has its own unique strengths and weaknesses. The combination of two imaging modalities that investigates the strengths of different methods might offer the prospect of improved diagnostic abilities. As more and more dual-modality imaging system have become clinically adopted, significant progress has been made toward the creation of dual-modality imaging probes, which can be used as novel tools for future multimodality systems. These all-in-one probes take full advantage of two different imaging modalities and could provide comprehensive information for clinical diagnostics. This review discusses the advantages and challenges in developing dual-modality imaging probes. (authors)

The presence of certain high-risk cytogenetic abnormalities, such as translocations (4;14) and (14;16) and deletion (17p), are known to have a negative impact on survival in multiple myeloma (MM). The phase 3 study ASPIRE (N = 792) demonstrated that progression-free survival (PFS) was significantly improved with carfilzomib, lenalidomide, and dexamethasone (KRd), compared with lenalidomide and dexamethasone (Rd) in relapsed MM. This preplanned subgroup analysis of ASPIRE was conducted to evaluate KRd vs Rd by baseline cytogenetics according to fluorescence in situ hybridization. Of 417 patients with known cytogenetic risk status, 100 patients (24%) were categorized with high-risk cytogenetics (KRd, n = 48; Rd, n = 52) and 317 (76%) were categorized with standard-risk cytogenetics (KRd, n = 147; Rd, n = 170). For patients with high-risk cytogenetics, treatment with KRd resulted in a median PFS of 23.1 months, a 9-month improvement relative to treatment with Rd. For patients with standard-risk cytogenetics, treatment with KRd led to a 10-month improvement in median PFS vs Rd. The overall response rates for KRd vs Rd were 79.2% vs 59.6% (high-risk cytogenetics) and 91.2% vs 73.5% (standard-risk cytogenetics); approximately fivefold as many patients with high- or standard-risk cytogenetics achieved a complete response or better with KRd vs Rd (29.2% vs 5.8% and 38.1% vs 6.5%, respectively). KRd improved but did not abrogate the poor prognosis associated with high-risk cytogenetics. This regimen had a favorable benefit-risk profile in patients with relapsed MM, irrespective of cytogenetic risk status, and should be considered a standard of care in these patients. This trial was registered at www.clinicaltrials.gov as #NCT01080391. © 2016 by The American Society of Hematology.

Background Dementia is one of the milestones of advanced Parkinson’s disease (PD), with its neuropathological substrate still being a matter of debate, particularly regarding its potential mechanistic implications. Objective The aim of this study was to review the relative importance of Lewy-related α-synuclein and Alzheimer’s tau and amyloid-β (Aβ) pathologies in disease progression and dementia in PD. Methods We reviewed studies conducted at the Queen Square Brain Bank, Institute of Neurology, University College London, using large PD cohorts. Results Cortical Lewy- and Alzheimer-type pathologies are associated with milestones of poorer prognosis and with non-tremor predominance, which have been, in turn, linked to dementia. The combination of these pathologies is the most robust neuropathological substrate of PD-related dementia, with cortical Aβ burden determining a faster progression to dementia. Conclusion The shared relevance of these pathologies in PD progression and dementia is in line with experimental data suggesting synergism between α-synuclein, tau and Aβ and with studies testing these proteins as disease biomarkers, hence favouring the eventual testing of therapeutic strategies targeting these proteins in PD.

Despite significant progress in the development of therapies for relapsing MS, progressive MS remains comparatively disappointing. Our objective, in this paper, is to review the current challenges in developing therapies for progressive MS and identify key priority areas for research. A collaborative was convened by volunteer and staff leaders from several MS societies with the mission to expedite the development of effective disease-modifying and symptom management therapies for progressive forms of multiple sclerosis. Through a series of scientific and strategic planning meetings, the collaborative identified and developed new perspectives on five key priority areas for research: experimental models, identification and validation of targets and repurposing opportunities, proof-of-concept clinical trial strategies, clinical outcome measures, and symptom management and rehabilitation. Our conclusions, tackling the impediments in developing therapies for progressive MS will require an integrated, multi-disciplinary approach to enable effective translation of research into therapies for progressive MS. Engagement of the MS research community through an international effort is needed to address and fund these research priorities with the ultimate goal of expediting the development of disease-modifying and symptom-relief treatments for progressive MS.

The Impact of Combination Therapy with a-Blockers and 5ARIs on the Progression of BPH.

Science.gov (United States)

Sountoulides, Petros; Gravas, Stavros

2015-01-01

Benign prostatic hyperplasia (BPH) can be a progressive disease for some men with significant impact on their quality of life due to worsening of symptoms, risk of acute urinary retention (AUR) and surgery. Certain clinical parameters such as age, prostate volume and PSA are able to predict those patients with BPH-associated LUTS that are at risk of disease progression. These patients will likely benefit most from medical therapy that provides symptom relief while at the same time may prevent disease progression. Studies have shown that a-blockers, although able to rapidly alleviate symptoms, have no effect on prostate volume, risk for AUR and BPH-related surgery. On the other hand 5ARIs have proven their efficacy in reducing prostate size, the risk of AUR and prostate surgery. Therefore combination therapy with an a-blocker and a 5ARI can be the mainstay of treatment for those patients at risk of BPH progression. Patients' perspective and their needs and expectations from treatment are other crucial parameters to consider in order selecting the optimal management of BPH. Therefore physicians should take into consideration the drug properties and also the patients' preferences before deciding on the optimal pharmacological treatment for BPH-associated LUTS.

This paper is an up-to-date systematic review on educational interventions addressing history taking. The authors noted that despite the plethora of specialized training programs designed to enhance students' interviewing skills there had not been a review of the literature to assess the quality of each published method of teaching history taking in undergraduate medical education based on the evidence of the program's efficacy. The databases PubMed, PsycINFO, Google Scholar, opengrey, opendoar and SSRN were searched using key words related to medical education and history taking. Articles that described an educational intervention to improve medical students' history-taking skills were selected and reviewed. Included studies had to evaluate learning progress. Study quality was assessed using the Medical Education Research Study Quality Instrument (MERSQI). Seventy-eight full-text articles were identified and reviewed; of these, 23 studies met the final inclusion criteria. Three studies applied an instructional approach using scripts, lectures, demonstrations and an online course. Seventeen studies applied a more experiential approach by implementing small group workshops including role-play, interviews with patients and feedback. Three studies applied a creative approach. Two of these studies made use of improvisational theatre and one introduced a simulation using Lego® building blocks. Twenty-two studies reported an improvement in students' history taking skills. Mean MERSQI score was 10.4 (range 6.5 to 14; SD = 2.65). These findings suggest that several different educational interventions are effective in teaching history taking skills to medical students. Small group workshops including role-play and interviews with real patients, followed by feedback and discussion, are widespread and best investigated. Feedback using videotape review was also reported as particularly instructive. Students in the early preclinical state might profit from approaches helping

To present a case of early primary open-angle glaucoma in which retinal nerve fiber layer thickness (RNFLT), ganglion cell complex (GCC), and visual field progression were accompanied with significant progression of peripapillary angioflow vessel density (PAFD) measured with optical coherence tomographic angiography. A 68-year-old female patient who was under topical intraocular pressure (IOP) lowering medication for 20 years for ocular hypertension of the right and preperimetric primary open-angle glaucoma of the left eye (with reproducible inferotemporal and superotemporal neuroretinal rim and RNFL loss) was prospectively imaged with the AngioVue OCT for RNFLT, GCC thickness, and PAFD, and investigated with the Octopus Normal G2 visual field test on the same days at 6-month intervals for 18 months, while the IOP of the left eye escaped from control. IOP of the left eye fluctuated between 14 and 30 mm Hg in the study period. RNFLT, GCC thickness, and peripapillary PAFD all decreased significantly (linear regression analysis, P=0.030, 0.040, and 0.020, respectively), and a significant 2.1 dB/y progression was seen for a superior visual field cluster. The RNFLT, peripapillary PAFD, and visual field of the right eye remained normal and unchanged. In our case IOP elevation, glaucomatous visual field conversion, and structural progression were accompanied with significant progressive decrease of peripapillary PAFD. The simultaneous thinning of RNFLT and GCC and decrease of peripapillary PAFD suggest that PAFD may potentially be an additional indicator of early progression in primary open-angle glaucoma.

Full Text Available This study examines the impact of bank size on bank regulatory capital ratios and risk-taking behavior using a panel dataset of 30 Bangladeshi commercial banks over the period 2008-2012. The relationship between bank regulatory capital ratios and bank risk-taking is also examined. For empirical analysis, generalized methods of moments (GMM panel method are used to explore the relationships among bank size, regulatory capital ratios and risk-taking behavior. Empirical results show that large banks hold lower amount of capital and take higher level of risk. Findings also show a reverse relationship between bank capital levels and bank risk-taking; that is, banks holding higher levels of regulatory capital are significantly less risky. Findings of this study has important implications for the Bangladeshi government, policy makers, banking regulators and bank stakeholders regarding bank size, regulatory capital requirements and overall banking sector risk-taking behavior.

Subtle inhomogeneities in the scanner's magnetic fields (B{sub 0} and B{sub 1}) alter the intensity levels of the structural magnetic resonance imaging (MRI) affecting the volumetric assessment of WMH changes. Here, we investigate the influence that (1) correcting the images for the B{sub 1} inhomogeneities (i.e. bias field correction (BFC)) and (2) selection of the WMH change assessment method can have on longitudinal analyses of WMH progression and discuss possible solutions. We used brain structural MRI from 46 mild stroke patients scanned at stroke onset and 3 years later. We tested three BFC approaches: FSL-FAST, N4 and exponentially entropy-driven homomorphic unsharp masking (E{sup 2}D-HUM) and analysed their effect on the measured WMH change. Separately, we tested two methods to assess WMH changes: measuring WMH volumes independently at both time points semi-automatically (MCMxxxVI) and subtracting intensity-normalised FLAIR images at both time points following image gamma correction. We then combined the BFC with the computational method that performed best across the whole sample to assess WMH changes. Analysis of the difference in the variance-to-mean intensity ratio in normal tissue between BFC and uncorrected images and visual inspection showed that all BFC methods altered the WMH appearance and distribution, but FSL-FAST in general performed more consistently across the sample and MRI modalities. The WMH volume change over 3 years obtained with MCMxxxVI with vs. without FSL-FAST BFC did not significantly differ (medians(IQR)(with BFC) = 3.2(6.3) vs. 2.9(7.4)ml (without BFC), p = 0.5), but both differed significantly from the WMH volume change obtained from subtracting post-processed FLAIR images (without BFC)(7.6(8.2)ml, p < 0.001). This latter method considerably inflated the WMH volume change as subtle WMH at baseline that became more intense at follow-up were counted as increase in the volumetric change. Measurement of WMH volume change remains

Research continues to show that pharmaceutical environmental contamination causes adverse effects to aquatic life. There are also public health risks associated with pharmaceuticals because in-home reserves of medications provide opportunities for accidental poisoning and intentional medication abuse. Pharmaceutical take back programs have been seen as a potential remedy for these issues; however, a thorough review of past programs indicates limited research has been conducted on take back programs. Furthermore, there are significant gaps in take back program research. To address these gaps and ultimately determine if take back programs could improve public health, research was conducted in conjunction with the take back program Denton drug disposal days held in Denton, Texas. Socioeconomic, demographic, and geographic characteristics of Denton drug disposal days participants were investigated using surveys and Geographic Information Systems. Potential impacts of the Denton drug disposal days program on public health were determined by comparing data from Denton drug disposal days events with data supplied by the North Texas Poison Center. Results suggest that Denton drug disposal days events may have prevented accidental poisonings or intentional abuse, however only qualitative comparisons support this statement and there was insufficient empirical evidence to support the conclusion that Denton drug disposal days events were exclusively responsible for public health improvements. An interesting finding was that there was a definitive travel threshold that influenced participation in Denton drug disposal days events. Overall, this study fills some geographic, socioeconomic, and demographic data gaps of take back programs and proposes methods to analyze and improve participation in future take back programs. These methods could also be applied to improve participation in other local environmentally-focused programs such as household hazardous collection events.

2017-03-01

Full Text Available Objectives: The aim of the study was the epidemiological analysis and evaluation of selected clinical and sociodemographic factors in Polish patients with primary progressive multiple sclerosis. Methods: The study included patients from 7 provinces in central and eastern Poland registered in the Registry of Patients with Multiple Sclerosis on 31 December 2016. The incidence of various forms of the disease was compared, and clinical, demographic and social disparities between relapsing-remitting and primary progressive multiple sclerosis were analysed. Results: Of 3,199 registered patients, 2,188 persons (66.2% had the relapsing-remitting form of multiple sclerosis, 774 (24.2% had the secondary progressive type and 307 (9.6% suffered from primary progressive disease. The first symptoms of primary progressive multiple sclerosis appeared almost 10 years later than in patients with the relapsing-remitting type (39.2 ± 11.4 vs. 29.8 ± 9.8. The period from the first symptoms to diagnosis was more than twice as long in patients with primary progressive multiple sclerosis (5.8 ± 3.4 as in those with relapsing-remitting disease (2.4 ± 1.6. The average degree of disability in the Expanded Disability Status Scale was similar and amounted to 3.2 ± 2.1 for relapsing-remitting and 3.6 ± 2.4 for primary progressive multiple sclerosis. The relapsing-remitting form was observed more often in women (2.4:1, and the primary progressive form appeared with equal frequency in both sexes (1:1. Disease-modifying treatment was received by 34% of patients with relapsing-remitting and in only 1.9% of patients with primary progressive multiple sclerosis. Conclusions: The primary progressive form affects approximately 10% of Polish patients with multiple sclerosis. The first symptoms appear at about 40 years of age with equal frequency in both sexes, and its diagnosis takes more than twice as much time as in the case of relapsing-remitting multiple

Increased risk taking in relation to chronic stress in young adults

Smarandita eCeccato

2016-01-01

Full Text Available Chronic stress is a public health problem that affects a significant part of the population. While the physiological damage it causes is under ongoing scrutiny, its behavioral effects have been overlooked. This is one of the first studies to examine the relation between chronic stress and decision-making, using a standard lottery paradigm. We measured learning-independent risk taking in the gain domain through binary choices between financially incentivized lotteries. We then measured self-reported chronic stress with the Trier Inventory for the Assessment of Chronic Stress (TICS. We additionally collected hair samples in a subsample of volunteers, in order to quantify chronic cortisol exposure. We discovered a significant, positive correlation between self-reported chronic stress and risk taking that is stronger for women than for men. This confirms part of the findings in acute stress research that show a connection between higher stress and increased risk taking. However, unlike the biologically-based results from acute stress research, we did not identify a significant relation between hair cortisol and behavior. In line with previous literature, we found a clear gender difference in risk taking and self-reports: women generally take less risk and report slightly higher stress levels than men. We conclude that perceived chronic stress can impact behavior in risky situations.

Empirical research on risk taking of listed financial institutions based on the perspective of corporate governance

Chen Hao

2017-03-01

Full Text Available After the financial crisis in 2008, the risk control of financial institutions has once again become the focus of attention. This paper selects the unbalanced panel data of 44 listed financial institutions in China from 2009 to 2013 for empirical analysis to study the risk taking of China’s listed financial institutions based on the perspective of corporate governance. Then the paper analyzes the effect of corporate governance on the risk taking of listed financial institutions based on the empirical analysis from four aspects. The results indicate that there is a significant negative correlation between the proportion of the largest shareholder’s shareholding and risk taking; a significant positive correlation between the size of the board of supervisors and risk taking; a significant positive correlation between the executive pay and risk taking, and a significant negative correlation between the equity incentive and risk taking. By comparison, the factors related to governance of board of directors have no significant effect on the risk taking of listed financial institutions.

Founder takes all: density-dependent processes structure biodiversity.

Science.gov (United States)

Waters, Jonathan M; Fraser, Ceridwen I; Hewitt, Godfrey M

2013-02-01

Density-dependent processes play a key role in the spatial structuring of biodiversity. Specifically, interrelated demographic processes, such as gene surfing, high-density blocking, and competitive exclusion, can generate striking geographic contrasts in the distributions of genes and species. Here, we propose that well-studied evolutionary and ecological biogeographic patterns of postglacial recolonization, progressive island colonization, microbial sectoring, and even the 'Out of Africa' pattern of human expansion, are fundamentally similar, underpinned by a 'founder takes all' density-dependent principle. Additionally, we hypothesize that older historic constraints of density-dependent processes are seen today in the dramatic biogeographic shifts that occur in response to human-mediated extinction events, whereby surviving lineages rapidly expand their ranges to replace extinct sister taxa.

Caffeine is neuroprotective in animal models of Parkinson's disease (PD) and caffeine intake is inversely associated with the risk of PD. This association may be influenced by the genotype of GRIN2A, which encodes an NMDA-glutamate-receptor subunit. In two placebo-controlled studies, we detected no association of caffeine intake with the rate of clinical progression of PD, except among subjects taking creatine, for whom higher caffeine intake was associated with more rapid progression. We now have analyzed data from 420 subjects for whom DNA samples and caffeine intake data were available from a placebo-controlled study of creatine in PD. The GRIN2A genotype was not associated with the rate of clinical progression of PD in the placebo group. However, there was a 4-way interaction between GRIN2A genotype, caffeine, creatine and the time since baseline. Among subjects in the creatine group with high levels of caffeine intake, but not among those with low caffeine intake, the GRIN2A T allele was associated with more rapid progression (p=0.03). These data indicate that the deleterious interaction between caffeine and creatine with respect to rate of progression of PD is influenced by GRIN2A genotype. This example of a genetic factor interacting with environmental factors illustrates the complexity of gene-environment interactions in the progression of PD. Copyright © 2017 Elsevier B.V.

{sup 18}F-fluorodeoxyglucose-positron emission tomography (FDG-PET) imaging is well known to have clinical significance in the initial staging and response evaluation of the many kinds of neoplasms. However, its role in the pediatric neuroblastoma is not clearly defined. In the present study, the clinical significance of FDG-PET/computed tomography (CT) in 123I- or 131I-metaiodobenzylguanidine (MIBG)-avid pediatric neuroblastoma was investigated. Twenty patients with neuroblastoma who undertook pretreatment FDG PET/CT at our institute between 2008 and 2015 and showed MIBG avidity were retrospectively enrolled in the present study. Clinical information—including histopathology, and serum markers—and several PET parameters—including SUVmax of the primary lesion (Psuv), target-to-background ratio (TBR), metabolic tumor volume (MTV), and coefficient of variation (CV)—were analyzed. The prognostic effect of PET parameters was evaluated in terms of progression-free survival (PFS). Total 20 patients (4.5 ± 3.5 years) were divided as two groups by disease progression. Six patients (30.0 %) experienced disease progression and one patient (5.0 %) died during follow-up period. There were not statistically significant in age, stage, MYCN status, primary tumor size, serum lactate dehydrogenase (LDH), neuron-specific enolase (NSE), and ferritin level between two groups with progression or no progression. However, Psuv (p = 0.017), TBR (p = 0.09), MTV (p = 0.02), and CV (p = 0.036) showed significant differences between two groups. In univariate analysis, PFS was significantly associated with Psuv (p = 0.021) and TBR (p = 0.023). FDG-PET parameters were significantly related with progression of neuroblastoma. FDG-PET/CT may have the potential as a valuable modality for evaluating prognosis in the patients with MIBG-avid pediatric neuroblastoma.

The field of violence risk assessment has matured considerably, possibly advancing beyond its own adolescence. At this point in the field's evolution, it is more important than ever for the development of any new device to be accompanied by a strong rationale and the capacity to provide a unique contribution. With this issue in mind, we first take stock of the field of adolescent risk assessment in order to describe the rapid progress that this field has made, as well as the gaps that led us to adapt the Short-Term Assessment of Risk and Treatability (START; Webster, Martin, Brink, Nicholls, & Desmarais, 2009) for use with adolescents. We view the Short-Term Assessment of Risk and Treatability: Adolescent Version (START:AV; Nicholls, Viljoen, Cruise, Desmarais, & Webster, 2010; Viljoen, Cruise, Nicholls, Desmarais, & Webster, in progress) as complementing other risk measures in four primary ways: 1) rather than focusing solely on violence risk, it examines broader adverse outcomes to which some adolescents are vulnerable (including self-harm, suicide, victimization, substance abuse, unauthorized leave, self-neglect, general offending); 2) it places a balanced emphasis on adolescents' strengths; 3) it focuses on dynamic factors that are relevant to short-term assessment, risk management, and treatment planning; and 4) it is designed for both mental health and justice populations. We describe the developmentally-informed approach we took in the adaptation of the START for adolescents, and outline future steps for the continuing validation and refinement of the START:AV.

Moral Progress: A Present-day Perspective on the Leading Enlightenment Idea

Directory of Open Access Journals (Sweden)

Andrzej Elżanowski

2013-06-01

Full Text Available Most Enlightenment thinkers believed that the World’s order (as ultimately based on divine laws is good and thus every gain of knowledge will have good consequences. Scientific process was assumed to entail moral progress. In fact some moral progress did occur in the Western civilization and science contributed to it, but it is widely incommensurate with the progress of science. The Enlightenment’s concept of a concerted scientific and moral progress proved largely wrong for several reasons. (1 Public morality and science evolve largely independently and may either enhance or inhibit each other. (2 There are no objective values to be read in the World’s order and simply followed. Instead, our real, subjective values and the moral systems they fuel have all been generated and shaped by evolution rather than designed to be universally good, and thus ought to be managed rather than simply followed. (3 Our evolved morality is flawed, deficient, prone to doctrinal manipulation and refractory to progress. (4 The majority of people show metaethical incompetence in failing to take a reasoned critical stand toward the principles and assumptions of received morals. This makes moral progress largely dependent on those who reach metaethical competence by transcending the conventional stages of moral development.

RandomForest4Life: a Random Forest for predicting ALS disease progression.

Science.gov (United States)

Hothorn, Torsten; Jung, Hans H

2014-09-01

We describe a method for predicting disease progression in amyotrophic lateral sclerosis (ALS) patients. The method was developed as a submission to the DREAM Phil Bowen ALS Prediction Prize4Life Challenge of summer 2012. Based on repeated patient examinations over a three- month period, we used a random forest algorithm to predict future disease progression. The procedure was set up and internally evaluated using data from 1197 ALS patients. External validation by an expert jury was based on undisclosed information of an additional 625 patients; all patient data were obtained from the PRO-ACT database. In terms of prediction accuracy, the approach described here ranked third best. Our interpretation of the prediction model confirmed previous reports suggesting that past disease progression is a strong predictor of future disease progression measured on the ALS functional rating scale (ALSFRS). We also found that larger variability in initial ALSFRS scores is linked to faster future disease progression. The results reported here furthermore suggested that approaches taking the multidimensionality of the ALSFRS into account promise some potential for improved ALS disease prediction.

Multiple myeloma is one of the most common haematological malignancies in the USA and is consistently preceded by monoclonal gammopathy of undetermined significance (MGUS). We aimed to assess the association between metformin use and progression of MGUS to multiple myeloma. We did a retrospective cohort study of patients registered in the US Veterans Health Administration database and diagnosed with MGUS between Oct 1, 1999, and Dec 31, 2009. We included patients (aged >18 years) with at least one International Classification of Diseases (9th revision) code for diabetes mellitus and one treatment for their diabetes before MGUS diagnosis. We reviewed patient-level clinical data to verify diagnoses and extract any available data for size of baseline M-protein and type of MGUS. We defined metformin users as patients with diabetes who were given metformin consistently for 4 years after their diabetes diagnosis and before multiple myeloma development, death, or censorship. Our primary outcome was time from MGUS diagnosis to multiple myeloma diagnosis. We used Kaplan-Meier curves and Cox models to analyse the association between metformin use and MGUS progression. We obtained data for 3287 patients, of whom 2003 (61%) were included in the final analytical cohort. Median follow-up was 69 months (IQR 49–96). 463 (23%) participants were metformin users and 1540 (77%) participants were non-users. 13 (3%) metformin users progressed to multiple myeloma compared with 74 (5%) non-users. After adjustment, metformin use was associated with a reduced risk of progression to multiple myeloma (hazard ratio 0·47, 95% CI 0·25–0·87). For patients with diabetes diagnosed with MGUS, metformin use for 4 years or longer was associated with a reduced risk of progression of MGUS to multiple myeloma. Prospective studies are needed to establish whether this association is causal and whether these results can be extrapolated to non-diabetic individuals. Barnes-Jewish Hospital Foundation

Central Blood Pressure and Chronic Kidney Disease Progression

Directory of Open Access Journals (Sweden)

Debbie L. Cohen

2011-01-01

Full Text Available Hypertension, diabetes, and proteinuria are well-recognized risk factors for progressive kidney function loss. However, despite excellent antihypertensive and antidiabetic drug therapies, which also often lower urinary protein excretion, there remains a significant reservoir of patients with chronic kidney disease who are at high risk for progression to end-stage kidney disease. This has led to the search for less traditional cardiovascular risk factors that will help stratify patients at risk for more rapid kidney disease progression. Among these are noninvasive estimates of vascular structure and function. Arterial stiffness, manifested by the pulse wave velocity in the aorta, has been established in a number of studies as a significant risk factor for kidney disease progression and cardiovascular endpoints. Much less well studied in chronic kidney disease are measures of central arterial pressures. In this paper we cover the physiology behind the generation of the central pulse wave contour and the studies available using these approaches and conclude with some speculations on the rationale for why measurements of central pressure may be informative for the study of chronic kidney disease progression.

[Riboflavin UVA crosslinking in progressive keratoconus].

Science.gov (United States)

Maier, P; Reinhard, T

2017-06-01

In patients with keratoconus, a progressive, ectatic disease of the cornea, the shape of the cornea is continuously changing leading to a reduction in visual acuity by progressive myopia and more and more (irregular) astigmatism. The symptomatic treatment consists of the prescription of glasses or special gas-permeable rigid contact lenses. Corneal tomography is generally used for diagnosis. After initial diagnosis of keratoconus, regular tomographic follow-ups should be performed. If clinically significant progression is found and confirmed by repeated measurements, riboflavin UVA collagen crosslinking should be offered to the patients. The aim of riboflavin UVA collagen crosslinking is to halt the progression of the disease to avoid further complications. The therapeutic principle is a combined effect of the photosensitizer riboflavin and UVA light. This stiffening effect of the corneal tissue halts the progression of keratoconus. The efficacy of this treatment has been demonstrated in various randomized, controlled trials.

Learning to cooperate is essential for progress in physics

Dickau, Jonathan J.

2012-06-01

At the 10th Frontiers of Fundamental Physics symposium, Gerard't Hooft stated that, for some of the advances we hope to see in Physics during the future, there must be a great deal of cooperation between physicists from different disciplines, as well as mathematicians, programmers, technologists, and others. This requires us to evolve a new mindset; however, as so much of our past progress has come out of a fiercely competitive process - especially since a critical review of our ideas about reality remains essential to making clear progress and checking our progress. We must also address the fact that some frameworks appear incompatible, as with relativity and quantum mechanics, whose unification remains distant despite years of attempts to find a quantum gravity theory. I explore the idea that playful exploration, using both left-brained and right-brained approaches to learning, allows us to resolve conflicting ideas by taking advantage of innate human developmental and learning strategies and brain structure. It may thus foster the kind of interdisciplinary cooperation we are hoping to see.

Evolving from academic to academic entrepreneur: overcoming barriers to scientific progress and finance.

Science.gov (United States)

Miller, Andrew D

2016-07-01

The overall goal of my career as an academic chemist has always been the design and creation of advanced therapeutics and diagnostics that address unmet medical need in the management of chronic diseases. Realising this goal has been an immensely difficult process involving multidisciplinary problem-driven research at the chemistry-biology-medicine interfaces. With success in the laboratory, I started seriously to question the value of remaining an academic whose career is spent in the pursuit of knowledge and understanding alone without making any significant effort to translate knowledge and understanding gained into products of genuine utility for public benefit. Therefore, I elected by choice to become an academic entrepreneur, seeking opportunities wherever possible for the translation of the best of my personal and collaborative academic research work into potentially valuable and useful products. This choice has brought with it many unexpected difficulties and challenges. Nevertheless, progress bas been made and sufficient learnt to suggest that this would be an appropriate moment to take stock and provide some personal reflections on what it takes to design and create advanced therapeutics and diagnostics in the laboratory then seek to develop, innovate and translate the best towards market.

Taking into account the Earth's rotation in experiments on search for the electric dipole moment of neutron

Silenko, A.Ya.

2007-01-01

Analysis of the problem of taking into account the Earth's rotation in a search for the electric dipole moment (EDM) of the neutron in experiments with ultracold neutrons and in a diffractional experiment is fulfilled. Taking into account the Earth's rotation in the diffractional experiment gives an exactly calculated correction which is negligible as compared with the accuracy reached at present time. In the experiments with ultracold neutrons, the correction is greater than the systematical error and the exact calculation of it needs further investigation. In this connection, further developments of diffractional method would considerably promote progress in the search for the electric dipole moment of the neutron

Clinical Significance of HER-2 Splice Variants in Breast Cancer Progression and Drug Resistance

Directory of Open Access Journals (Sweden)

Claire Jackson

2013-01-01

Full Text Available Overexpression of human epidermal growth factor receptor (HER-2 occurs in 20–30% of breast cancers and confers survival and proliferative advantages on the tumour cells making HER-2 an ideal therapeutic target for drugs like Herceptin. Continued delineation of tumour biology has identified splice variants of HER-2, with contrasting roles in tumour cell biology. For example, the splice variant 16HER-2 (results from exon 16 skipping increases transformation of cancer cells and is associated with treatment resistance; conversely, Herstatin (results from intron 8 retention and p100 (results from intron 15 retention inhibit tumour cell proliferation. This review focuses on the potential clinical implications of the expression and coexistence of HER-2 splice variants in cancer cells in relation to breast cancer progression and drug resistance. “Individualised” strategies currently guide breast cancer management; in accordance, HER-2 splice variants may prove valuable as future prognostic and predictive factors, as well as potential therapeutic targets.

Progressive taxation, income inequality, and happiness.

Oishi, Shigehiro; Kushlev, Kostadin; Schimmack, Ulrich

2018-01-01

Income inequality has become one of the more widely debated social issues today. The current article explores the role of progressive taxation in income inequality and happiness. Using historical data in the United States from 1962 to 2014, we found that income inequality was substantially smaller in years when the income tax was more progressive (i.e., a higher tax rate for higher income brackets), even when controlling for variables like stock market performance and unemployment rate. Time lag analyses further showed that higher progressive taxation predicted increasingly lower income inequality up to 5 years later. Data from the General Social Survey (1972-2014; N = 59,599) with U.S. residents (hereafter referred to as "Americans") showed that during years with higher progressive taxation rates, less wealthy Americans-those in the lowest 40% of the income distribution-tended to be happier, whereas the richest 20% were not significantly less happy. Mediational analyses confirmed that the association of progressive taxation with the happiness of less wealthy Americans can be explained by lower income inequality in years with higher progressive taxation. A separate sample of Americans polled online (N = 373) correctly predicted the positive association between progressive taxation and the happiness of poorer Americans but incorrectly expected a strong negative association between progressive taxation and the happiness of richer Americans.

Objectives: The ability to differentiate between brain tumor progression and radiation therapy induced necrosis is critical for appropriate patient management. In order to improve the differential diagnosis, we combined fluorine-18 2-fluoro-deoxyglucose positron emission tomography ({sup 18}F-FDG PET), proton magnetic resonance spectroscopy ({sup 1}H MRS) and histological data to develop a multi-parametric machine-learning model. Methods: We enrolled twelve post-therapy patients with grade 2 and 3 gliomas that were suspicious of tumor progression. All patients underwent {sup 18}F-FDG PET and {sup 1}H MRS. Maximal standardized uptake value (SUVmax) of the tumors and reference regions were obtained. Multiple 2D maps of choline (Cho), creatine (Cr), and N-acetylaspartate (NAA) of the tumors were generated. A support vector machine (SVM) learning model was established to take imaging biomarkers and histological data as input vectors. A combination of clinical follow-up and multiple sequential MRI studies served as the basis for assessing the clinical outcome. All vector combinations were evaluated for diagnostic accuracy and cross validation. The optimal cutoff value of individual parameters was calculated using Receiver operating characteristic (ROC) plots. Results: The SVM and ROC analyses both demonstrated that SUVmax of the lesion was the most significant single diagnostic parameter (75% accuracy) followed by Cho concentration (67% accuracy). SVM analysis of all paired parameters showed SUVmax and Cho concentration in combination could achieve 83% accuracy. SUVmax of the lesion paired with SUVmax of the white matter as well as the tumor Cho paired with the tumor Cr both showed 83% accuracy. These were the most significant paired diagnostic parameters of either modality. Combining all four parameters did not improve the results. However, addition of two more parameters, Cho and Cr of brain parenchyma contralateral to the tumor, increased the accuracy to 92

Intentional forgetting: note-taking as a naturalistic example.

Eskritt, Michelle; Ma, Sierra

2014-02-01

In the present study, we examined whether note-taking as a memory aid may provide a naturalistic example of intentional forgetting. In the first experiment, participants played Concentration, a memory card game in which the identity and location of pairs of cards need to be remembered. Before the game started, half of the participants were allowed to study the cards, and the other half made notes that were then unexpectedly taken away. No significant differences emerged between the two groups for remembering identity information, but the study group remembered significantly more location information than did the note-taking group. In a second experiment, we examined whether note-takers would show signs of proactive interference while playing Concentration repeatedly. The results indicated that they did not. The findings suggest that participants adopted an intentional-forgetting strategy when using notes to store certain types of information.

Significance of the combined tests application in serum and liquor of patients with suspected neurosyphilis

2007-01-01

Full Text Available Background. Tertiary syphilis develops in 8-40% of untreated patients. It is most commonly manifested in the form of neurosyphilis, which can be asymptomatic taking the form of tabes dorsalis or progressive paralyze. Nowadays, in the developed countries, progressive paralyze is a rather rare disease, although the incidence of this disease has been rising within the last decades. Case report. We reported a 74-year-old male with the clinical image of dementia showing psychotic symptoms. On cytobiochemical examination of cerebrospinal liquor, hyperproteinorhacmia of 0.70 g/l with the normal number of cells was revealed. Computed tomography of the brain showed the marked cortical cerebral and cerebellar reduction changes with multiple ischemic lesions. Within a routine examination of patients with demention, we performed serologic reactions to syphilis out of which the Veneral Disease Researc Laboratory (VDRL test in serum and liquor was unreactive, while the Treponema pallidum hemagglutination (TPNA test in serum and liquor was positive. Positivity in serum and liquor was additionally confirmed by the Western blot method and fluoroscent treponema antibody (FTA test. The treatment with benzathine fenylpenicilline 2.4 g once weekly resulted in significant improving the psychotic symptoms of the disease even after two weeks. Conclusion. This case report showed that within the differential diagnostics in patients with demention or psychotic disorder it is obligatory to consider syphilis of the nervous system, as well as to apply a combination of various tests which, besides the typical liquor findings, significantly improve the accuracy of diagnosis. Such approach is especially important regarding the fact that neurosyphilis can remain clinically quite asymptomatic for a long period, which could lead to late therapy, while, on the contrary, an adequate and timely treatment can contribute to a significant recovery of any patients.

Taking stock of the occupational safety and health challenges of nanotechnology: 2000-2015

Engineered nanomaterials significantly entered commerce at the beginning of the 21st century. Concerns about serious potential health effects of nanomaterials were widespread. Now, approximately 15 years later, it is worthwhile to take stock of research and efforts to protect nanomaterial workers from potential risks of adverse health effects. This article provides and examines timelines for major functional areas (toxicology, metrology, exposure assessment, engineering controls and personal protective equipment, risk assessment, risk management, medical surveillance, and epidemiology) to identify significant contributions to worker safety and health. The occupational safety and health field has responded effectively to identify gaps in knowledge and practice, but further research is warranted and is described. There is now a greater, if imperfect, understanding of the mechanisms underlying nanoparticle toxicology, hazards to workers, and appropriate controls for nanomaterials, but unified analytical standards and exposure characterization methods are still lacking. The development of control-banding and similar strategies has compensated for incomplete data on exposure and risk, but it is unknown how widely such approaches are being adopted. Although the importance of epidemiologic studies and medical surveillance is recognized, implementation has been slowed by logistical issues. Responsible development of nanotechnology requires protection of workers at all stages of the technological life cycle. In each of the functional areas assessed, progress has been made, but more is required.

Several risk scores for disease progression in Smoldering Multiple Myeloma (SMM) patients have been proposed, however, all have been developed using single center registries. To examine risk factors for time to progression (TTP) to Multiple Myeloma (MM) for SMM we analyzed a nationwide population......-based cohort of 321 newly diagnosed SMM patients registered within the Danish Multiple Myeloma Registry between 2005 and 2014. Significant univariable risk factors for TTP were selected for multivariable Cox regression analyses. We found that both an M-protein ≥ 30g/l and immunoparesis significantly influenced......-high risk of transformation to MM. Using only immunoparesis and M-protein ≥ 30g/l, we created a scoring system to identify low, intermediate and high risk SMM. This first population-based study of SMM patients confirms that an M-protein ≥ 30g/l and immunoparesis remain important risk factors for progression...

A tale of three theories: Feyerabend and Popper on progress and the aim of science.

Science.gov (United States)

Tambolo, Luca

2015-06-01

In this paper, three theories of progress and the aim of science are discussed: (i) the theory of progress as increasing explanatory power, advocated by Popper in The logic of scientific discovery (1935/1959); (ii) the theory of progress as approximation to the truth, introduced by Popper in Conjectures and refutations (1963); (iii) the theory of progress as a steady increase of competing alternatives, which Feyerabend put forward in the essay "Reply to criticism. Comments on Smart, Sellars and Putnam" (1965) and defended as late as the last edition of Against method (1993). It is argued that, contrary to what Feyerabend scholars have predominantly assumed, Feyerabend's changing attitude towards falsificationism-which he often advocated at the beginning of his career, and vociferously attacked in the 1970s and 1980s-must be explained by taking into account not only Feyerabend's very peculiar view of the aim of science, but also Popper's changing account of progress.

LIVER FUNCTION CHANGES IN PATIENTS WITH SPONDYLOARTHRITIS TAKING NONSTEROIDAL ANTI-INFLAMMATORY DRUGS OVER A LONG PERIOD: RESULTS OF A 10-YEAR PROGRESS PROSPECTIVE STUDY

2016-01-01

Full Text Available Objective: to assess liver function changes in patients with spondyloarthritis (SpA taking NSAIDs regularly over a long period.Patients and methods. The data obtained during a 10-year PROGRESS prospective single-center cohort study of functional status, activity, and comorbidity (including gastrointestinal tract diseases in patients with SpA were analyzed. The data of 363 SpA patients receiving NSAIDs regularly over a long period and followed up for 10 years were also explored. The changes that had occurred over a decade in the liver enzyme levels, the number of discontinued NSAID treatments because of a persistent increase in liver enzyme levels, and the number of prescriptions of hepatoprotective agents were analyzed.Results. For 10 years, 18 patients with SpA discontinued their NSAID intake due to elevated liver enzyme levels (≥3 times greater than the reference value; during that time, the same increase in enzyme levels was observed in 2 healthy individuals (χ2 =1.39; p=0.2. In the patients with SpA as compared to the healthy individuals, the relative risk of abnormal liver function was 1.19 (95% CI, 1.009–1.405; odds ratio was 2.9 (95% CI, 0.65–12.95. There was no increased risk for discontinuation of some NSAIDs, including nimesulide (χ2 =0.03, p=0.85, the frequency of using hepatoprotective drugs was proved to be highest for diclofenac sodium, ibuprofen, nimesulide, and ketoprofen.Conclusion. The regular long-term (as long as 10 years use of NSAIDs to treat SpA is associated with treatment discontinuation because of elevated enzyme levels in every 10 patients. The maximum rate of discontinuation of NSAIDs due to a persistent increase in liver enzyme levels is observed 6–8 years after their regular use, so long-term NSAID therapy requires continuous monitoring of hepatic safety. The longterm intake of nimesulide, as compared with other NSAIDs, is shown to be unassociated with the higher rate of its discontinuation because of

Four major areas of research effort are reported: dust transport, distribution of transuranics in sediments, evaluation of critical ecological pathways for radionuclides, and terrestrial ecosystem compartmentalization of transuranics. Progress also is described in programs dealing with Rocky Flats Plant land management, a differential alpha emitter analysis project, quality control procedures, the effects of chlorine addition on biological oxygen measurements, and evaluation of Plant-related incident response involving wounded wildlife. In the dust transport project, data continued to be collected on transuranic airborne concentrations and surface-soil activity levels for a field known to have above-back-ground levels of transuranics. The data show principal airborne activity resides on nonrespirable (> 3-μm aerodynamic diameter) particles. Progress in the sediment sampling program included fitting and modification of the sampling platform; taking of preliminary cores, dredges, and pond-side samples from Lindsay Pond (a near background water body); and acquisition of required sample preparation and storage facilities. The critical pathways project continued, and data were obtained on transuranic levels in garden vegetables grown in soil (with excess transuranic levels) within and outside a greenhouse. Progress in studies of terrestrial ecological distributions of transuranics included collection for radionuclide analysis of approximately 70 rodents on two study plots east of the Plant's security fence

The Cultural Boundaries of Perspective-Taking: When and Why Perspective-Taking Reduces Stereotyping.

Science.gov (United States)

Wang, Cynthia S; Lee, Margaret; Ku, Gillian; Leung, Angela K-Y

2018-06-01

Research conducted in Western cultures indicates that perspective-taking is an effective social strategy for reducing stereotyping. The current article explores whether and why the effects of perspective-taking on stereotyping differ across cultures. Studies 1 and 2 established that perspective-taking reduces stereotyping in Western but not in East Asian cultures. Using a socioecological framework, Studies 2 and 3 found that relational mobility, that is, the extent to which individuals' social environments provide them opportunities to choose new relationships and terminate old ones, explained our effect: Perspective-taking was negatively associated with stereotyping in relationally mobile (Western) but not in relationally stable (East Asian) environments. Finally, Study 4 examined the proximal psychological mechanism underlying the socioecological effect: Individuals in relationally mobile environments are more motivated to develop new relationships than those in relationally stable environments. Subsequently, when this motivation is high, perspective-taking increases self-target group overlap, which then decreases stereotyping.

The last two years have been marked by real progress in networking in HEP. Home-made developments, studies and plans have given way to the use of real networks involving hundreds of HEP and other computers and based on externally produced software and hardware. Within the last year, the first generation of industrial software products following some of the international standards for networking have become available. Related developments are taking place in networking for on-line systems and indeed the LEP experiments are distinguished by their heavy and crucial reliance on both local and wide-area networks. This paper describes the progress made at CERN since the last two years and looks at perspectives for the future. (orig.)

Psychosocial predictors of coronary artery calcification progression in postmenopausal women.

2011-01-01

Coronary artery calcification (CAC) has been associated with psychosocial factors in some but not all cross-sectional analyses. The goal of this study was to determine whether positive and negative psychosocial factors prospectively predict CAC progression in postmenopausal women. Participants from the Healthy Women Study who also participated in the Pittsburgh Mind-Body Center protocol (n = 149) completed self-report psychosocial measures before two electron beam computed tomographic scans of CAC separated by an average of 3.3 years. Results of exploratory factor analysis were used to create aggregate psychosocial indices: psychological risk (depressive symptoms, perceived stress, cynicism, and anger-in) and psychosocial resources (optimism, purpose in life, mastery, self-esteem, and social support). The psychological risk index predicted significantly greater CAC progression over 3 years (β = 0.16, p = .035, ΔR(2) = 0.03), whereas the psychosocial resources index was not predictive of CAC progression (β = -0.08, p = .30, ΔR(2) = 0.01). On individual scales, higher scores on cynicism emerged as a significant predictor of CAC progression, along with a trend linking anger-in to atherosclerosis progression. A post hoc analysis showed a significant interaction between cynicism and anger-in (β = 0.20, p = .01, ΔR(2) = 0.03), such that women reporting high levels of both cynicism and anger suppression exhibited the most CAC progression. These findings highlight psychosocial risk factors that may accelerate the progression of subclinical atherosclerosis in older women, suggest the potential importance of examining combinations of psychosocial risk factors, and identify potential targets for psychological interventions to reduce cardiovascular risk.

Static Progressive Orthoses for Elbow Contracture: A Systematic Review

Bin Chen

2017-01-01

Full Text Available Background. As one of the most common musculoskeletal complications following trauma, elbow contracture is a frequent source of disabled daily activities. Conventional interventions are inadequate to provide favorable outcome. The static progressive orthoses are getting popular in the treatment of this problem. Objective. The purpose of this review was to assess the effectiveness of static progressive orthoses for elbow contracture. Methods. Literatures when written in English published during 1 January 1997 and 31 January 2017 were searched in the following databases: Web of Science, Cochrane Library, PubMed, and EBSCOhost. Articles are quality-assessed by two assessors, each article was summarized in evidence tables, and a narrative synthesis was also performed. Results. Ten clinical trials were included. The study design and outcome measures used varied. Significant immediate improvement in the range of motion was reported by all studies, and those effects were still significant at follow-up. No significant difference was shown between static progressive and dynamic orthoses for elbow contracture in one randomized control trial. Conclusions. Current low-quality evidence suggested that static progressive orthoses provided assistance for elbow contracture through improving range of motion. Further research is recommended using high-quality randomized controlled trials.

Progressive rendering is becoming a popular alternative to precomputational approaches to appearance design. However, progressive algorithms create images exhibiting visual artifacts at early stages. A user study investigated these artifacts' effects on user performance in appearance design tasks. Novice and expert subjects performed lighting and material editing tasks with four algorithms: random path tracing, quasirandom path tracing, progressive photon mapping, and virtual-point-light rendering. Both the novices and experts strongly preferred path tracing to progressive photon mapping and virtual-point-light rendering. None of the participants preferred random path tracing to quasirandom path tracing or vice versa; the same situation held between progressive photon mapping and virtual-point-light rendering. The user workflow didn’t differ significantly with the four algorithms. The Web Extras include a video showing how four progressive-rendering algorithms converged (at http://youtu.be/ck-Gevl1e9s), the source code used, and other supplementary materials.

Radiographic examination takes on an automated image

Aman, J.

1988-01-01

Automation can be effectively applied to nondestructive testing (NDT). Until recently, film radiography used in NDT was largely a manual process, involving the shooting of a series of x-rays, manually positioned and manually processed. In other words, much radiographic work is being done the way it was over 50 years ago. Significant advances in automation have changed the face of manufacturing, and industry has shared in the benefits brought by such progress. The handling of parts, which was once responsible for a large measure of labor costs, is now assigned to robotic equipment. In nondestructive testing processes, some progress has been achieved in automation - for example, in real-time imaging systems. However, only recently have truly automated NDT begun to emerge. There are two major reasons to introduce automation into NDT - reliability and productivity. Any process or technique that can improve the reliability of parts testing could easily justify the capital investments required

Organizing Effects of Testosterone and Economic Behavior: Not Just Risk Taking

Brañas-Garza, Pablo; Rustichini, Aldo

2011-01-01

Recent literature emphasizes the role that testosterone, as well as markers indicating early exposure to T and its organizing effect on the brain (such as the ratio of second to fourth finger, ), have on performance in financial markets. These results may suggest that the main effect of T, either circulating or in fetal exposure, on economic behavior occurs through the increased willingness to take risks. However, these findings indicate that traders with a low digit ratio are not only more profitable, but more able to survive in the long run, thus the effect might consist of more than just lower risk aversion. In addition, recent literature suggests a positive correlation between abstract reasoning ability and higher willingness to take risks. To test the two hypotheses of testosterone on performance in financial activities (effect on risk attitude versus a complex effect involving risk attitude and reasoning ability), we gather data on the three variables in a sample of 188 ethnically homogeneous college students (Caucasians). We measure a digit ratio, abstract reasoning ability with the Raven Progressive Matrices task, and risk attitude with choice among lotteries. Low digit ratio in men is associated with higher risk taking and higher scores in abstract reasoning ability when a combined measure of risk aversion over different tasks is used. This explains both the higher performance and higher survival rate observed in traders, as well as the observed correlation between abstract reasoning ability and risk taking. We also analyze how much of the total effect of digit ratio on risk attitude is direct, and how much is mediated. Mediation analysis shows that a substantial part of the effect of T on attitude to risk is mediated by abstract reasoning ability. PMID:22242144

Hyperuricemia is common in approximately 50% of patients with kidney failure due to decreased uric acid excretion, and it has been recently known as an independent factor in the progression of renal insufficiency. Allopurinol inhibits the production of uric acid. The aim of this study was to evaluate the effect of allopurinol on chronic kidney disease progression. In a clinical trial, patients with stages 3 and 4 of chronic kidney disease were divided into two groups to receive allopurinol, 100 mg, daily and placebo for 12 months. Patients' kidney function and serum uric acid levels were assessed at baseline and 3, 6, and 12 months after initial administration. Subgroups of patients with severe and mild glomerular filtration rate (GFR) impairment (GFR, 15 mL/min/1.73 m2 to 30 mL/min/1.73 m2 and 30 mL/min/1.73 m2 to 60 mL/min/1.73 m2, respectively), were compared between the groups. Serum uric acid levels decreased significantly during after 12 months of allopurinol administration (P = .004). In patients with severe GFR impairment, serum creatinine levels did not decrease significantly and there was no significant increase in GFR, but in those with mild GFR impairment, serum creatinine levels decreased and GFR increase significantly (P kidney disease progression and could be administered with other effective medications for controlling the kidney disease.

G-20 Clean Energy, and Energy Efficiency Deployment and Policy Progress, a report prepared by the International Energy Agency (IEA) in collaboration with the G-20 Clean Energy and Energy Efficiency Working Group, provides an overview of clean energy and energy efficiency technology deployment and summarises support policies in place across G-20 countries. The report highlights that while clean energy technology deployment has made steady progress and energy efficiency improvements have been made, continued reliance on fossil fuels to meet growth in global energy demand presents a significant challenge. Scaling-up the deployment of renewable energy, in addition to improving end-use efficiency, enhancing the efficiency of fossil fuel based power generation, and supporting the widespread deployment of CCS will, therefore, also be crucial aspects of the transition to a cleaner energy future. Because the G-20 group of countries represent close to 80% of energy-related CO2 emissions, by developing and deploying energy efficiency and clean energy technologies, they are presented with a unique opportunity to make collective progress in transitioning the global energy system. IEA Deputy Executive Director Richard Jones emphasised the importance of G-20 efforts, saying, 'The IEA welcomes this important collaboration with the G-20. Enhanced deployment of clean energy technologies and of energy efficiency improvements offers energy security and environmental benefits. It will also enable cost savings over the medium and long term -- an aspect that is particularly relevant at a time of economic uncertainty. We believe that enhanced policy assessment and analysis, building on this initial report, will enable governments to take more cost effective and efficient policy decisions.'

In its “Roadmap to a Resource Efficient Europe” (Communication COM(2011) 571 of 20 September 2011), the European Commission (EC) established an ambitious goal for the European Union (EU), that of achieving no land take by 2050; towards this aim, a key milestone for the year 2020 was set, by stating that European policies in the programming period 2014–2020 ought to consider both their direct and their indirect impacts on land use in the EU. Within this framework, this paper builds upon the findings of a previous paper (Zoppi and Lai, 2014), in which we estimated the magnitude of land take over a short period of time (2003–2008) in Sardinia, an Italian NUTS2 region, and we assessed whether and how land take is related to a set of variables that are regarded as important determinants in the literature, such as parcel size, accessibility, and proximity to main cities and towns, to the coastline, or to protected areas. In this paper we study the land-taking process taking Sardinia as a case study, in two larger time periods, 1960–1990 and 1990–2008. We assess if, and to what extent, these factors reveal similar, or different, effects in the two periods, and try to identify consistencies concerning the determinants of land take. - Highlights: • Population density and parcel size significantly affect the magnitude of land take. • The presence of nature conservation areas hinders land taking processes. • Extensive urbanization might effectively preserve non-artificial land. • Balanced accessibility of settlements and nature conservation regional policies can effectively contrast land take. • Size of non-artificial land parcels that become artificial is negatively and significantly connected to land take.

Full Text Available In this paper, taking construction project as the research object, the relationship between the project maturity index calculated by the construction project technical risks with different fine degree and the project progress index is studied, and the equilibrium relationship between the Party A’s utility curve and the Party B’s cost curve of using project maturity index and project progress index as the research variables is analyzed. The results show that, when the construction project technical risk division is more precise, the conjoint utility of the project's technical maturity index and the project progress is higher, and the project’s Party A and Party B two sides are closer to the optimal equilibrium. This shows that the construction project technical risk must be finely divided, and managed and controlled respectively, which will help to improve the conjoint utility of the project Party A and Party B two sides.

Research purpose: The aim of the study was to investigate the contributions of self-efficacy and perceived organisational support when taking charge at work. Motivation for the study: Although many previous studies have examined the antecedents of taking charge in North American business environments, we know little about taking charge in the developing economies of Africa. Research about taking charge will provide valuable information for managers of businesses in developing countries in Africa. Research design, approach and method: This study used a cross-sectional survey design to examine the contributions of self-efficacy and perceived organisational support to taking charge at work amongst 201 bank workers in Nsukka, Southeast Nigeria. Main findings: Regression analysis results showed that self-efficacy had a significant relationship with taking charge at work. The results also showed a statistically significant relationship between perceived organisational support and taking charge at work. Practical/managerial implications: The implications of the results are that interventions that focus on improving self-efficacy will contribute to the behaviours of employees who take charge. In addition, organisations that develop strategies to make employees perceive the organisation as supportive will also have members that engage in more supervisory behaviours. Contribution/value-add: This study was one of the first attempts to investigate taking charge at work in a developing economy of Africa. The results of the study, that self-efficacy and perceived organisational support have relationships with taking charge at work, will contribute to a better understanding of the concept and to building robust theories.

The efficiency of the Data Acquisition (DAQ) of the Compact Muon Solenoid (CMS) experiment for LHC Run 2 is constantly being improved. A~significant factor affecting the data taking efficiency is the experience of the DAQ operator. One of the main responsibilities of the DAQ operator is to carry out the proper recovery procedure in case of failure of data-taking. At the start of Run 2, understanding the problem and finding the right remedy could take a considerable amount of time (up to many minutes). Operators heavily relied on the support of on-call experts, also outside working hours. Wrong decisions due to time pressure sometimes lead to an additional overhead in recovery time. To increase the efficiency of CMS data-taking we developed a new expert system, the DAQExpert, which provides shifters with optimal recovery suggestions instantly when a failure occurs. DAQExpert is a~web application analyzing frequently updating monitoring data from all DAQ components and identifying problems based on expert knowl...

The role of electronic assessment of adherence in the education and counseling of children taking growth hormone: progress and challenges.

Science.gov (United States)

Haverkamp, Fritz; Norgren, Svante; Horne, Rob; Gasteyger, Christoph

There are numerous issues surrounding adherence in children taking recombinant human growth hormone (rh-GH). New technologies capable of accurately recording/monitoring may highlight some of these issues, and have value in optimizing adherence levels through education and counseling. The intention of this review is to guide healthcare professionals (HCPs). PubMed, Google Scholar and citations in published papers were used to substantiate the views expressed by the authors. Both perceptional and practical factors influence the adherence levels of children taking rh-GH. Understanding such factors may help to identify the characteristics of ideal rh-GH devices and their potential impact on adherence. New technologies, such as electronic monitors, may facilitate patient-provider discussions on adherence, and help identify barriers that are amenable to change. Monitoring adherence may also help differentiate nonadherence from biological low response to rh-GH therapy. However, the medical, psychological, social and ethical aspects of electronic assessment require further investigation.

Current diagnostic criteria require the language dysfunction to remain isolated for at least two years, and to remain the salient feature as the disease progresses, usually to involve other domains such as behavior, executive functions, and judgment. Although PPA in its early stages can usually be differentiated from probable Alzheimer’s disease (PRAD and the behavioral variant of frontotemporal lobar degeneration by the absence of significant changes in memory and behavior, and the preservation of activities daily living, progression of the disease often leads to deficits more consistent with the latter. Underlying etiologies remain heterogeneous: the neuropathological characteristics associated with frontotemporal lobar degeneration, cortocobasal degeneration, and motor neuron disease are usually found. There is a strong genetic susceptibility with affliction of first-degree relatives with similar disease in up to 40 to 50% in some series. Pathogenic mutations in genes coding for the proteins tau and progranulin have been isolated. These are leading to a better understanding of the neuropathological mechanisms and hopefully targeted disease-modifying therapy. Current therapy is limited to improving mood symptoms and targeting behavior changes as they develop. Referral to specialized centers where speech therapy, counseling, and education

2015-08-01

Racing games have emerged as top-selling products in the video and computer game industry. The effect of playing racing games on the inclination of gamers to take risks has been investigated. Two experiments were conducted. In experiment 1, the impact of personality traits on the effects of playing racing games on risk-taking inclination was examined. The Vienna Test System, which includes the Eysenck Personality Profile Test and the Vienna Risk-Taking Test, was used to measure risk-taking inclination and risk-taking while driving. Experiment 2 was designed and conducted to analyse the effects of different intensity levels of car racing games on risk-taking inclination, and to study the relationship between physiological data and risk-taking inclination. Physiological data on skin conductance, heart rate and blood pressure were measured with the NeuroDyne System. Participants playing a racing game were more inclined to take risks in critical road traffic situations than those playing a neutral game. The adventurousness dimension of the Eysenck Personality Profile Test correlated significantly positively with risk-taking inclination. More importantly, the effect of the intensity level of a racing game on risk-taking inclination was significant. The higher the intensity level of the racing game, the higher the risk-taking inclination while driving. The effect of intensity level of the racing game on skin conductance was significantly positive. Skin conductance correlated significantly positively with risk-taking inclination. The effect of playing racing games on risk-taking inclination is linked to personality and physiological data. Some recommendations are proposed as a result of this study for racing game management.

To identify factors that may lead to a rapid progression in macula-on rhegmatogenous retinal detachment (RRD), in particular, those that may lead to macular involvement. Observational, prospective, single-center study. Patients referred for surgery due to primary rhegmatogenous retinal detachment with the macula on between 2009 and 2013 were included. Relevant factors analyzed included age, time delay until surgery, lens status, myopia, the detachment's location and configuration as well as number, size and type of retinal breaks. Eyes underwent optical coherence tomography to detect macular detachment. A multivariate analysis was performed to investigate the effect of several factors in the progression of retinal detachment. A total of 116 eyes of 116 patients were included. Mean time delay between admission and surgery was 1.8 ± 1.4 days. Progression was observed in 19.8% of the eyes. Of those, 47.8% presented macular detachment. Ten of the 11 (90.9%) eyes presenting progression involving the macula also exhibited a bullous configuration, which was the only parameter that correlated significantly with detachment progression in patients with (p = 0.0036) and without (p = 0.0014) macular involvement. For the first time in a prospective trial, a bullous configuration was found to be a highly significant predictor for progression in macula-on detachments. Our data support prompt surgery in patients diagnosed with bullous macula-on RRD.

Clinical studies have shown that patients with exaggerated risk-taking tendencies have high baseline levels of norepinephrine. In this work, we systemically manipulated norepinephrine levels in rats and studied their behavioral changes in a probabilistic discounting task, which is a paradigm for gauging risk taking. This study aims to explore the effects of the selective norepinephrine reuptake inhibitor (atomoxetine at doses of 0.6, 1.0 and 1.8 mg/kg), and receptor selective antagonists (propranolol at a single dose of 1.0/kg, and prazosin at a single dose of 0.1 mg/kg), on risk taking using a probabilistic discounting task. In this task, there were two levers available to rats: pressing the 'small/certain' lever guaranteed a single food pellet, and pressing the 'large/risky' lever yielded either four pellets or none. The probability of receiving four food pellets decreased across the four experimental blocks from 100% to 12.5%. Atomoxetine increased the tendency to choose the large/risky lever. It significantly reduced the lose-shift effect (i.e. pressing a different lever after losing a trial), but did not affect the win-stay effect (i.e. pressing the same lever after winning a trial). Furthermore, co-administration of beta-adrenoreceptor antagonist, propranolol, eliminated the effects of atomoxetine on risk taking and the lose-shift effect; but co-administration of alpha1-adrenoreceptor antagonist, prazosin, did not. Atomoxetine boosted NE levels and increased risk taking. This was because atomoxetine decreased rats' sensitivity to losses. These effects were likely mediated by beta-adrenoreceptor.

The UK fuel poverty strategy: 5th annual progress report 2007

International Nuclear Information System (INIS)

2007-12-01

This fifth annual progress report details government progress in 2007 in tackling fuel poverty and movement towards targets. The United Kingdom were the first country in the world to recognise the issue of fuel poverty and to put in place measures to tackle the issue, including spending 20 billion pounds sterling on benefits and programmes since the year 2000. The report covers progress to date, schemes and initiatives to tackle fuel poverty, the energy market and looks ahead to the future. Progress and development of the schemes across the devolved nations are also considered. This report is the first to publish the Government's proposals for the Carbon Emissions Reduction Target (CERT) priority group, which were laid before Parliament on 5th December 2007. This report is the first to present the fuel poverty figures for 2005, and shows the effects of rising energy prices. The Government continues to take action to ensure that the energy market is working properly, and to encourage reform in the EU on energy market liberalisation - this should reduce pressure on prices. Those in fuel poverty have much to gain by switching supplier and this report outlines the action taken by Ofgem and Energywatch to encourage this

Students (N = 79) took lecture notes either by hand (n = 40) or by computer (n = 39) and then completed either a computer or a paper-based assessment. When note taking and assessment formats were congruent, students scored significantly higher on the assessment when compared to students whose note taking and assessment format were incongr...

Shifting closeness: interpersonal effects of personal goal progress.

Science.gov (United States)

Fitzsimons, Gráinne M; Fishbach, Ayelet

2010-04-01

In this article, we examine how the shifting motivational priority of personal goals affects relationship closeness. We hypothesize that people will draw closer to significant others who are instrumental (vs. noninstrumental) for a goal that has not been progressing well-a goal that is thus high in motivational priority. Once the goal has progressed successfully, we predict that people will cease to draw closer to instrumental others. Five studies support these predictions by showing that the impact of goal progress on reduced preference for instrumental others (Experiment 1) depends on the framing of progress as partial attainment (vs. greater commitment, Experiment 2) and the intention to balance across goals (vs. focus on one goal; Experiments 3-4). We find that moving away from instrumental others post progress is functional, in that it allows for drawing closer to those who are instrumental for alternative goals (Experiment 5).

1. On note taking.

Science.gov (United States)

Plaut, Alfred B J

2005-02-01

In this paper the author explores the theoretical and technical issues relating to taking notes of analytic sessions, using an introspective approach. The paper discusses the lack of a consistent approach to note taking amongst analysts and sets out to demonstrate that systematic note taking can be helpful to the analyst. The author describes his discovery that an initial phase where as much data was recorded as possible did not prove to be reliably helpful in clinical work and initially actively interfered with recall in subsequent sessions. The impact of the nature of the analytic session itself and the focus of the analyst's interest on recall is discussed. The author then describes how he modified his note taking technique to classify information from sessions into four categories which enabled the analyst to select which information to record in notes. The characteristics of memory and its constructive nature are discussed in relation to the problems that arise in making accurate notes of analytic sessions.

Progress in elementary particle theory, 1950-1964

International Nuclear Information System (INIS)

Gell-Mann, M.

1989-01-01

This final chapter of the book lists advances in elementary particle theory from 1950 to 1964 in an order of progressive understanding of ideas rather than chronologically. Starting with quantum field theory and the important discoveries within it, the author explains the connections and items missing in this decade, but understood later. The second part of the chapter takes the same pattern, but deals with basic interactions (strong, electromagnetic, weak and gravitational) and elementary particles, including quarks. By 1985, theory had developed to such a degree that it was hoped that the long-sought-after unified field theory of all elementary particles and interactions of nature might be close at hand. (UK)

A not-so-grim tale: how childhood family structure influences reproductive and risk-taking outcomes in a historical U.S. Population.

Sheppard, Paula; Garcia, Justin R; Sear, Rebecca

2014-01-01

Childhood family structure has been shown to play an important role in shaping a child's life course development, especially in industrialised societies. One hypothesis which could explain such findings is that parental investment is likely to be diluted in families without both natural parents. Most empirical studies have examined the influence of only one type of family disruption or composition (e.g. father absence) making it difficult to simultaneously compare the effects of different kinds of family structure on children's future outcomes. Here we use a large, rich data source (n=16,207) collected by Alfred Kinsey and colleagues in the United States from 1938 to 1963, to examine the effects of particular childhood family compositions and compare between them. The dataset further allows us to look at the effects of family structure on an array of traits relating to sexual maturity, reproduction, and risk-taking. Our results show that, for both sexes, living with a single mother or mother and stepfather during childhood was often associated with faster progression to life history events and greater propensity for risk-taking behaviours. However, living with a single father or father and stepmother was typically not significantly different to having both natural parents for these outcomes. Our results withstand adjustment for socioeconomic status, age, ethnicity, age at puberty (where applicable), and sibling configuration. While these results support the hypothesis that early family environment influences subsequent reproductive strategy, the different responses to the presence or absence of different parental figures in the household rearing environment suggests that particular family constructions exert independent influences on childhood outcomes. Our results suggest that father-absent households (i.e. single mothers or mothers and stepfathers) are most highly associated with subsequent fast life history progressions, compared with mother-absent households

2,4-diacetylphloroglucinol (DAPG)-producing Pseudomonas spp. in the P. fluorescens complex are primarily responsible for a natural suppression of take-all of wheat known as take-all decline (TAD) in many fields in the USA. P. brassicacearum, the most common DAPG producer found in TAD soils in the Pacific Northwest (PNW) of the USA, has biocontrol, growth promoting and phytotoxic activities. In this study, we explored how the wheat cultivar affects the level of take-all suppression when grown in a TAD soil, and how cultivars respond to colonization by P. brassicacearum. Three cvs. Tara, Finley and Buchanan supported similar rhizosphere population sizes of P. brassicacearum when grown in a TAD soil, however they developed significantly different amounts of take-all. Cultivars Tara and Buchanan developed the least and most take-all, respectively, and Finley showed an intermediate amount of disease. However, when grown in TAD soil that was pasteurized to eliminate both DAPG producers and take-all suppression, all three cultivars were equally susceptible to take-all. The three cultivars also responded differently to the colonization and phytotoxicity of P. brassicacearum strains Q8r1-96 and L5.1-96, which are characteristic of DAPG producers in PNW TAD soils. As compared to cv. Tara, cv. Buchanan showed significantly reduced seedling emergence and root growth when colonized by P. brassicacearum, and the response of Finley was intermediate. However, all cultivars emerged equally when treated with a DAPG-deficient mutant of Q8r1-96. Our results indicate that wheat cultivars grown in a TAD soil modulate both the robustness of take-all suppression and the potential phytotoxicity of the antibiotic DAPG.

Little is known about documentation during transitions of patient care between clinical specialties. Therefore, we examined the focus, structure and purpose of physician progress notes for patients transferred from the intensive care unit (ICU) to hospital ward to identify opportunities to improve communication breaks. This was a prospective cohort study in ten Canadian hospitals. We analyzed physician progress notes for consenting adult patients transferred from a medical-surgical ICU to hospital ward. The number, length, legibility and content of notes was counted and compared across care settings using mixed-effects linear regression models accounting for clustering within hospitals. Qualitative content analyses were conducted on a stratified random sample of 32 patients. A total of 447 patient medical records that included 7052 progress notes (mean 2.1 notes/patient/day 95% CI 1.9-2.3) were analyzed. Notes written by the ICU team were significantly longer than notes written by the ward team (mean lines of text 21 vs. 15, p notes; mean agreement of patient issues was 42% [95% CI 31-53%]. Qualitative analyses identified eight themes related to focus (central point - e.g., problem list), structure (organization, - e.g., note-taking style), and purpose (intention - e.g., documentation of patient course) of the notes that varied across clinical specialties and physician seniority. Important gaps and variations in written documentation during transitions of patient care between ICU and hospital ward physicians are common, and include discrepancies in documentation of patient information.

Caregiver Leave-Taking in Spain: Rate, Motivations, and Barriers.

This paper aims to (1) determine the rate of (full- and part-time) caregiver leave-taking in Spain, (2) identify the reasons conducive to a more intense use of this resource, and (3) ascertain the main obstacles to its use, as perceived by caregivers. All 896 people covered by the sample were engaging in paid work and had cared for dependent adults in the last 12 years. This resource, in particular the full-time alternative, was found to be a minority option. The data showed that legal, work-related, and family and gender norm issues are the four types of factors that determine the decision to take such leaves. The most significant obstacles to their use are the forfeiture of income and the risk of losing one's job. Our results suggest that income replacement during a leave would increase the take-up of these resources. Moreover, enlargement of public care services would promote the use of leave as a free choice of caregivers.

The present study aimed to investigate differences in prognosis based on human papillomavirus (HPV) infection, persistent infection and genotype variations for patients exhibiting atypical squamous cells of undetermined significance (ASCUS) in their initial Papanicolaou (PAP) test results. A latent Dirichlet allocation (LDA)-based tool was developed that may offer a facilitated means of communication to be employed during patient-doctor consultations. The present study assessed 491 patients (139 HPV-positive and 352 HPV-negative cases) with a PAP test result of ASCUS with a follow-up period ≥2 years. Patients underwent PAP and HPV DNA chip tests between January 2006 and January 2009. The HPV-positive subjects were followed up with at least 2 instances of PAP and HPV DNA chip tests. The most common genotypes observed were HPV-16 (25.9%, 36/139), HPV-52 (14.4%, 20/139), HPV-58 (13.7%, 19/139), HPV-56 (11.5%, 16/139), HPV-51 (9.4%, 13/139) and HPV-18 (8.6%, 12/139). A total of 33.3% (12/36) patients positive for HPV-16 had cervical intraepithelial neoplasia (CIN)2 or a worse result, which was significantly higher than the prevalence of CIN2 of 1.8% (8/455) in patients negative for HPV-16 (Paged ≥51 years (38.7%) than in those aged ≤50 years (20.4%; P=0.036). Progression from persistent infection to CIN2 or worse (19/34, 55.9%) was higher than clearance (0/105, 0.0%; Page and long infection period with a clinical progression of CIN2 or worse. Therefore, LDA results may be presented as explanatory evidence during time-constrained patient-doctor consultations in order to deliver information regarding the patient's status. PMID:28587376

Kim-Spoon, Jungmeen; Holmes, Christopher; Deater-Deckard, Kirby

2014-01-01

Background Regulation of negative affect is critical to healthy development in childhood and adolescence. We conducted a longitudinal study examining the moderating role of attention control in the effects of anger and fear on changes in risk-taking behaviors from early to middle adolescence. Method The sample involved participants from the Study of Early Child Care and Youth Development (SECCYD), assessed at 9, 11, and 15 years of age. Composite scores for anger, fear, and attention control were computed using indicators from multiple informants, and risk-taking behaviors were assessed based on adolescents’ self-reports. Results Latent difference score analysis indicated significant moderating effects of attention control showing that increased anger between 9 and 11 years was related to increases in risk-taking behaviors between 11 and 15 years only for adolescents with low attention control but not for adolescents with high attention control. In contrast, significant moderating effects of attention control for the link between fear and risk-taking behaviors suggested increased fear between 9 and 11 years tended to be associated with decreases in risk-taking behaviors between 11 and 15 years only for adolescents with high attention control but not for adolescents with low attention control. Conclusions Attention control regulates the connections between negative affect such as anger and fear with changes in adolescent risk-taking behaviors. Our data suggest the protective role of strong attention control against the development of risk-taking behaviors in adolescence as it demotes the effects of anger and promotes the effects of fear.

MODERN TAKE-OFF POWER DIAGNOSTICS

Full Text Available Take-off power is one of the main biomotor abilities for predicting the results of many sport disciplines. It plays a particularly important role in motor situations when the take-off power is combined with the velocity of movement. The core aim of this study was to establish and analyse the fundamental kinematic, dynamic and electromyographic parameters which generate the results of selected take-off power tests. The experimental procedure involved two elite female triple jumpers. According to Bosco’s protocol the following tests were selected: squat jump, countermovement jump and drop jump – 25 cm. The following were analysed: jump height, take-off time, flight time, take-off velocity, maximum take-off force, angle velocity of the ankle, knee and hip joints, force impulse and duration of the eccentric and concen ric phases of take-off. The 3D-kinematic analysis of jumps was based on a system of nine SMART-e 600 video-cameras (BTS Bioengineering, with a 60 Hz frequency and a 768 x 576 pixel resolution. The kinematic parameters were processed using the BTS SMART Suite programme. Dynamic parameters were established by means of two separate force-plat forms, namely Kistler, Type 9286A. The analysis of the electromyographic activity (EMG of the following muscles: m. erector spinae, m. gluteus maximus, m. rectus femoris, m. vastus medialis, m. vastus lateralis, m. biceps femoris, m. tibialis anterior and m. gastrocnemius medialis was made using a 16-channel electromyograph (BTS Pocket EMG, MYOLAB. The research showed that the jump height (h as a criterion of explosive power was generated by: the velocity of take-off, flight time, force impulse in the concentric phase and optimal knee joint angle. The analysis of the EMG activation in vertical jumps showed the proximaldistal principle of muscle activation. In the first phase of the take-off action, the trunk extensors (m. erector spinae and hip extensors (m. gluteus maximus are activated. In the

In this study, we measured the vertical and horizontal take-off forces, plantar pressures and activation patterns of four muscles (vastus lateralis, gluteus maximus, tibialis anterior, gastrocnemius) in 10 ski jumpers in simulated laboratory conditions when wearing either training shoes or ski jumping boots. We found significant differences in vertical (P boots condition resulted in a smaller displacement in the final position of the following joint angles: ankle angle (P knee angle (P boots condition, significantly more pressure was recorded under the heel (P knee and hip extensors when wearing jumping boots. We conclude that the stiffness of the structure of the jumping boots may result in a forward shift of pressure, thus limiting the effective vertical force. To avoid this pressure shift, the pattern of movement of simulated take-offs should be carefully controlled, particularly when wearing training shoes.

In an individual-level analysis we examined the effect of atorvastatin on glycaemia progression in type 2 diabetes and whether glycaemia effects reduce the prevention of cardiovascular disease (CVD) with atorvastatin. The study population comprised 2,739 people taking part in the Collaborative Atorvastatin Diabetes Study (CARDS) who were randomised to receive atorvastatin 10 mg or placebo and who had post-randomisation HbA1c data. This secondary analysis used Cox regression to estimate the effect of atorvastatin on glycaemia progression, defined as an increase in HbA1c of ≥ 0.5% (5.5 mmol/mol) or intensification of diabetes therapy. Mixed models were used to estimate the effect of atorvastatin on HbA1c as a continuous endpoint. Glycaemia progression occurred in 73.6% of participants allocated placebo and 78.1% of those allocated atorvastatin (HR 1.18 [95% CI 1.08, 1.29], p effect was seen in on-treatment analyses: HR 1.20 (95% CI 1.07, 1.35), p = 0.001. The net mean treatment effect on HbA1c was 0.14% (95% CI 0.08, 0.21) (1.5 mmol/mol). The effect did not increase through time. Diabetes treatment intensification alone did not differ with statin allocation. Neither baseline nor 1-year-attained HbA1c predicted subsequent CVD, and the atorvastatin effect on CVD did not vary by HbA1c change (interaction p value 0.229). The effect of atorvastatin 10 mg on glycaemia progression among those with diabetes is statistically significant but very small, is not significantly different between sexes, does not increase with duration of statin and does not have an impact on the magnitude of CVD risk reduction with atorvastatin.

Successful development of Heavy Ion Fusion (HIF) will require scientific and technology advances in areas of targets, drivers and chambers. Design work on heavy ion targets indicates that high gain (60-130) may be possible with a -3-6 MJ driver depending on the ability to focus the beams to small spot sizes. Significant improvements have been made on key components of heavy ion drivers, including sources, injectors, insulators and ferromagnetic materials for long-pulse induction accelerator cells, solid-state pulsers, and superconducting quadrupole magnets. The leading chamber concept for HIF is the thick-liquid-wall HYLEE-II design, which uses an array of flibe jets to protect chamber structures from x-ray, debris, and neutron damage. Significant progress has been made in demonstrating the ability to create and control the types of flow needed to form the protective liquid blanket. Progress has also been made on neutron shielding for the final focus magnet arrays with predicted lifetimes now exceeding the life of the power plant. Safety analyses have been completed for the HYLEE-II design using state-of-the-art codes. Work also continues on target fabrication and injection for HE. A target injector experiment capable of > 5 Hz operation has been designed and construction will start in 2002. Methods for mass production of hohlraum targets are being evaluated with small-scale experiments and analyses. Progress in these areas will be reviewed

Full Text Available Background: Adverse cardiovascular events have been reported in body builders taking anabolic steroids. Adverse effects of AAS on endothelial function can initiate atherosclerosis. This study evaluates endothelial function in body builders using AAS, compared with non-steroids using athletes as controls. Methods: We recruited 30 nonsmoking male body builders taking AAS, 14 in build up phase, 8 in work out phase, and 8 in post steroid phase, and 30 nonsmoking male athletes who denied ever using steroids. Serum lipids and fasting plasma glucose were measured to exclude dyslipidemia and diabetes. Brachial artery diameter was measured by ultrasound at rest, after cuff inflation, and after sublingual glyceriltrinitrate (GTN to determine flow mediated dilation (FMD, nitro mediated dilation (NMD and ratio of FMD to NMD (index of endothelial function. Result: Use of AAS was associated with higher body mass index (BMI and low density lipoprotein–cholesterol (LDL-C. Mean ratio of flow mediated dilatation after cuff deflation to post GTN dilatation of brachial artery (index of endothelial function in body builders taking AAS was significantly lower than control group (0.96(0.05 versus 1(0.08; p=0.03. After adjusting BMI, age and weight, no significant difference was seen in index of endothelial function between two groups (p=0 .21. Conclusion: Our study indicates that taking AAS in body builders doesn’t have direct effect on endothelial function. Future study with bigger sample size and measurement of AAS metabolites is recommended. Key words: endothelium, lipids, anabolic steroids, body builders

Significant increase in violent crimes in recent years forced Icelandic men to take action against violence. Television was seen as a major contributory factor in increasing violence. Surveys indicate that 10-15 years after television broadcasting commences in a particular society, the incidence of crime can be expected to double. While the majority of the individuals arrested for violent crimes are men, being male does not necessarily mean being violent. The Men's Committee of the Icelandic Equal Rights Council initiated a week-long information and education campaign under the theme "Men Against Violence". This campaign involved several events including an art exhibit, speeches on violence in families, treatment sought by those who are likely to resort to violence, booklet distribution among students in secondary schools, and a mass media campaign to raise public awareness on this pressing problem.

Full Text Available This study examined the encoding specificity principle in relation to traditional and computer-based note taking and assessment formats in higher education. Students (N = 79 took lecture notes either by hand (n = 40 or by computer (n = 39 and then completed either a computer or a paper-based assessment. When note taking and assessment formats were congruent, students scored significantly higher on the assessment when compared to students whose note taking and assessment format were incongruent. These findings highlight the importance of research on how in-class technology may affect student performance, and suggest that faculty and administrators seek to coordinate and standardize the use of assessment and note taking technologies where possible.

Familial dysautonomia (FD) is an autosomal recessive congenital neuropathy that is caused by a mutation in the gene for inhibitor of kappa B kinase complex-associated protein ( IKBKAP ). Although FD patients suffer from multiple neuropathies, a major debilitation that affects their quality of life is progressive blindness. To determine the requirement for Ikbkap in the developing and adult retina, we generated Ikbkap conditional knockout (CKO) mice using a TUBA1a promoter-Cre ( Tα1-Cre ). In the retina, Tα1-Cre expression is detected predominantly in retinal ganglion cells (RGCs). At 6 months, significant loss of RGCs had occurred in the CKO retinas, with the greatest loss in the temporal retina, which is the same spatial phenotype observed in FD, Leber hereditary optic neuropathy, and dominant optic atrophy. Interestingly, the melanopsin-positive RGCs were resistant to degeneration. By 9 months, signs of photoreceptor degeneration were observed, which later progressed to panretinal degeneration, including RGC and photoreceptor loss, optic nerve thinning, Müller glial activation, and disruption of layers. Taking these results together, we conclude that although Ikbkap is not required for normal development of RGCs, its loss causes a slow, progressive RGC degeneration most severely in the temporal retina, which is later followed by indirect photoreceptor loss and complete retinal disorganization. This mouse model of FD is not only useful for identifying the mechanisms mediating retinal degeneration, but also provides a model system in which to attempt to test therapeutics that may mitigate the loss of vision in FD patients.

Nondestructive Evaluation Program: Progress in 1986

International Nuclear Information System (INIS)

1987-07-01

The increasing cost of equipment for power generating plants and the potential increases in productivity and safety available through rapidly developing Nondestructive Evaluation (NDE) technology led EPRI to initiate a Nondestructive Evaluation Program in 1974. To date, the major focus has been on light water reactor inspection problems; however, increased application to other systems is now under way. This report presents a comprehensive review of the EPRI effort in the NDE area. Most of the report consists of contractor-supplied progress reports on each current project. An organizational plan of the program is presented in overview. In addition, organization from several viewpoints is presented, e.g., in-service inspection operators, R and D personnel, and utility representatives. The report summarizes significant progress made since the previous EPRI Special Report NP-4315-SR was issued in May 1986. Section 1 contains information about the program organization, and the sections that follow contain contractor-supplied progress reports of each current project. The progress reports are grouped by plant components - pipe, pressure vessel, steam generator and boiler tubes, and turbine. In addition, Part 6 is devoted to discussions of technology transfer

Health insurance take-up by the near-elderly.

To examine the effect of price on the demand for health insurance by early retirees between the ages of 55 and 64. Administrative health plan enrollment data from a medium-sized U.S. employer. The analysis takes advantage of a natural experiment created by the firm's health insurance contribution policy. The amount the firm contributes toward retiree health insurance coverage depends on when a person retired and her years of service at that date. As a result of this policy, there is considerable variation in out-of-pocket premiums faced by individuals in the data. This variation is independent of the nonprice attributes of the health insurance plans offered and is plausibly exogenous to individual characteristics that are likely to affect the demand for insurance. A probit model is used to estimate the decision to take-up employer-sponsored health insurance by early retirees between the ages of 55 and 64. Demand for insurance is measured as a function of out-of-pocket premiums and a set of individual characteristics. We find that price has a small but statistically significant effect on the decision to take up coverage. Estimated price elasticities range from -0.10 to -0.16, depending on the sample. The implied elasticities are comparable with results found in previous studies using very different data. Our estimates indicate that policy proposals for a Medicare buy-in or a nongroup tax credit will have a modest impact on take-up rates of near-elderly retirees.

Can risk-taking propensity be thought of as a trait that captures individual differences across domains, measures, and time? Studying stability in risk-taking propensities across the lifespan can help to answer such questions by uncovering parallel, or divergent, trajectories across domains and measures. We contribute to this effort by using data from respondents aged 18 to 85 in the German Socio-Economic Panel Study (SOEP) and by examining (1) differential stability, (2) mean-level differences, and (3) individual-level changes in self-reported general (N = 44,076) and domain-specific (N =11,903) risk-taking propensities across adulthood. In addition, we investigate (4) the correspondence between cross-sectional trajectories of self-report and behavioral measures of social (trust game; N = 646) and nonsocial (monetary gamble; N = 433) risk taking. The results suggest that risk-taking propensity can be understood as a trait with moderate stability. Results show reliable mean-level differences across the lifespan, with risk-taking propensities typically decreasing with age, although significant variation emerges across domains and individuals. Interestingly, the mean-level trajectory for behavioral measures of social and nonsocial risk taking was similar to those obtained from self-reported risk, despite small correlations between task behavior and self-reports. Individual-level analyses suggest a link between changes in risk-taking propensities both across domains and in relation to changes in some of the Big Five personality traits. Overall, these results raise important questions concerning the role of common processes or events that shape the lifespan development of risk-taking across domains as well as other major personality facets.

For more than three decades the coconut mite Aceria guerreronis Keifer is one of the most important pests of coconut palms and has recently spread to many coconut production areas worldwide. Colonization of coconut palms is thought to arise from mites dispersing aerially after take-off from other plants within the same plantation or other plantations. The underlying dispersal behaviour of the mite at take-off, in the airborne state and after landing is largely unknown and this is essential to understand how they spread from tree to tree. In this article we studied whether take-off to aerial dispersal of coconut mites is preceded by characteristic behaviour, whether there is a correlation between the body position preceding aerial dispersal and the direction of the wind, and whether the substrate (outer surface of coconut bracts or epidermis) and the wind speed matter to the decision to take-off. We found that take-off can sometimes be preceded by a raised body stance, but more frequently take-off occurs while the mite is walking or resting on its substrate. Coconut mites that become airborne assumed a body stance that had no relation to the wind direction. Take-off was suppressed on a substrate providing food to coconut mites, but occurred significantly more frequently on the outer surface of coconut bracts than on the surface of the fruit. For both substrates, take-off frequency increased with wind speed. We conclude that coconut mites have at least some degree of control over take-off for aerial dispersal and that there is as yet no reason to infer that a raised body stance is necessary to become airborne.

Brain structural correlates of risk-taking behavior and effects of peer influence in adolescents.

Directory of Open Access Journals (Sweden)

Myoung Soo Kwon

Full Text Available Adolescents are characterized by impulsive risky behavior, particularly in the presence of peers. We discriminated high and low risk-taking male adolescents aged 18-19 years by assessing their propensity for risky behavior and vulnerability to peer influence with personality tests, and compared structural differences in gray and white matter of the brain with voxel-based morphometry (VBM and diffusion tensor imaging (DTI, respectively. We also compared the brain structures according to the participants' actual risk-taking behavior in a simulated driving task with two different social conditions making up a peer competition situation. There was a discrepancy between the self-reported personality test results and risky driving behavior (running through an intersection with traffic lights turning yellow, chancing a collision with another vehicle. Comparison between high and low risk-taking adolescents according to personality test results revealed no significant difference in gray matter volume and white matter integrity. However, comparison according to actual risk-taking behavior during task performance revealed significantly higher white matter integrity in the high risk-taking group, suggesting that increased risky behavior during adolescence is not necessarily attributed to the immature brain as conventional wisdom says.

To compare longitudinal glaucoma progression detection using optical coherence tomography (OCT) and visual field (VF). Validity assessment. We analyzed subjects with more than 4 semi-annual follow-up visits (every 6 months) in the multicenter Advanced Imaging for Glaucoma Study. Fourier-domain optical coherence tomography (OCT) was used to map the thickness of the peripapillary retinal nerve fiber layer (NFL) and ganglion cell complex (GCC). OCT-based progression detection was defined as a significant negative trend for either NFL or GCC. VF progression was reached if either the event or trend analysis reached significance. The analysis included 356 glaucoma suspect/preperimetric glaucoma (GS/PPG) eyes and 153 perimetric glaucoma (PG) eyes. Follow-up length was 54.1 ± 16.2 months for GS/PPG eyes and 56.7 ± 16.0 for PG eyes. Progression was detected in 62.1% of PG eyes and 59.8% of GS/PPG eyes by OCT, significantly (P glaucoma. While the utility of NFL declines in advanced glaucoma, GCC remains a sensitive progression detector from early to advanced stages. Copyright © 2017 Elsevier Inc. All rights reserved.

To evaluate the effect of treatment escalation on the rate of visual field progression in patients with primary open-angle glaucoma (POAG). Multicenter database study. We reviewed the electronic records of 171 patients with POAG under medical hypotensive treatment who underwent 5 consecutive visits 6 months apart before and after medical treatment escalation or additive laser trabeculoplasty. We calculated the rate of visual field progression (mean deviation change per year) before and after treatment escalation. The mean duration of follow-up was 5.1±0.5 years and the mean number of visual field examinations was 10.2±0.2. In 139 eyes with medical treatment escalation, the rate of progression was significantly reduced [from -0.57 to -0.29 dB/y; P=0.022; intraocular pressure (IOP) reduction 11.1%]. In detail, the rate of progression was significantly reduced after escalation from mono to dual therapy, dual to triple therapy, and from mono to triple therapy (-0.35 to -0.24 dB/y, P=0.018; -1.01 to -0.48 dB/y, P=0.038; -1.04 to -0.35 dB/y, P=0.020, respectively). In 32 eyes with additive laser trabeculoplasty, the rate of progression was significantly reduced (-0.60 to -0.24 dB/y; P=0.014; IOP reduction 9.4%). Medical treatment escalation or additive laser trabeculoplasty significantly reduced the rate of visual field progression in POAG. Larger IOP reduction has a greater probability of reducing glaucoma progression.

Full Text Available The main purpose of this study was to determine the effect of single leg hop progression and double legs hop progression exercise to increase speed and explosive power of leg muscles. Plyometric is one of the training methods that can increase explosive power. There are many models of plyometric training including single leg hop progression and double leg hop progression. This research was experimental using match subject design techniques. The subjects of this study were 39 students who joined basketball school club. There were 3 groups in this study: Group 1 were 13 students who given sin¬gle leg hop progression exercise, Group 2 were 13 students who given double legs hop progression exercise, Group 3 were 13 students who given conventional exercise. The data was collected during pre test and post test by testing 30m speed running and vertical jump. The data was analyzed using Analysis of Varians (Anova. It was found that there were significantly increased on speed and explosive power of leg muscles of Group 1 and Group 2. It can be stated that single leg hop progression exercise was more effective than double leg hop progression exercise. The recent findings supported the hypothesis that single leg hop progression and double legs hop progression exercise can increase speed and explosive power of leg muscles. These finding were supported by some previous studies (Singh, et al, 2011; Shallaby, H.K., 2010. The single leg hop progression is more effective than double legs hop progression. This finding was consistent with some previous evidences (McCurdy, et al, 2005; Makaruk et al, 2011.

Full Text Available The reflective–impulsive model (RIM has been employed to explain various health behaviors. The present study used RIM to predict a spontaneous physical activity behavior. Specifically, 107 participants (75 females; Mage = 20.6 years, SD = 1.92 years completed measures of (1 reflections about spontaneous physical activity, as indexed by self-report questionnaire; (2 impulse toward physical activity, as indexed by the manikin task; and (3 (state self-control, as indexed by the Stroop task. The dependent variable was whether participants took the stairs or the elevator to the study laboratory. Results revealed reflections toward spontaneous physical activity positively predicted stair-taking. Further, a significant impulse toward physical activity × self-control interaction was observed. This interaction revealed that participants with high self-control who had a high impulse toward PA were more likely to take the stairs than their counterparts with a low impulse toward PA, whereas the opposite was the case for participants with low self-control. However, the impulse × self-control interaction was not significant when employing a self-report measure of trait self-control. Thus, RIM may be a good framework with which to consider spontaneous physical activity, but careful consideration must be given when examining variables within RIM (e.g., the boundary condition of self-control.

There has been controversy regarding whether bioavailability of certain oral oncology drugs should be maximized by taking these medications with food, irrespective of label instructions in the dosing and administration section. To provide insight into this controversy, we conducted an in-depth analysis for oral antineoplastic drugs approved by the Food and Drug Administration in 2000-2016 and identified important issues influencing food labeling decisions. Furthermore, a case study involving sonidegib, a drug approved for locally advanced basal cell carcinoma with a significant food effect on exposure, was used to demonstrate the consequences of failure to adhere to food label recommendations using drug-specific population pharmacokinetic and exposure-toxicity models. In 2000-2009, 80% (4 out of 5) of all approved oral antineoplastics with increased bioavailability in the fed state were labeled as "take on empty stomach." In contrast, we found that in 2010-2016 there is a greater diversity in food recommendations for drugs with increased bioavailability in the fed state. Currently, many oral oncology drugs are given with food to maximize their bioavailability; however, as seen from our case study of sonidegib, failure to fully adhere to label recommendations to either take with food or not could lead to adverse consequences in terms of safety and efficacy. © 2017, The American College of Clinical Pharmacology.

Full Text Available Until recently, multiple sclerosis has been viewed as an entirely inflammatory disease without acknowledgment of the significant neurodegenerative component responsible for disease progression and disability. This perspective is being challenged by observations of a dissociation between inflammation and neurodegeneration where the neurodegenerative component may play a more significant role in disease progression. In this review, we explore the relationship between mitochondrial dysfunction and neurodegeneration in multiple sclerosis. We review evidence that the ketogenic diet can improve mitochondrial function and discuss the potential of the ketogenic diet in treating progressive multiple sclerosis for which no treatment currently exists.

Regulatory Mode and Risk-Taking: The Mediating Role of Anticipated Regret.

Panno, Angelo; Lauriola, Marco; Pierro, Antonio

2015-01-01

We propose that decision maker's regulatory mode affects risk-taking through anticipated regret. In the Study 1 either a locomotion or an assessment orientation were experimentally induced, and in the Studies 2 and 3 these different orientations were assessed as chronic individual differences. To assess risk-taking we used two behavioral measures of risk: BART and hot-CCT. The results show that experimentally induced assessment orientation--compared to locomotion--leads to decreased risk-taking through increased anticipated regret (Study 1). People chronically predisposed to be in the assessment state take less risk through increased anticipated regret (Study 2 and Study 3). Study 2 results also show a marginally non-significant indirect effect of chronic locomotion mode on BART through anticipated regret. Differently, Study 3 shows that people chronically predisposed to be in the locomotion state take greater risk through decreased anticipated regret, when play a dynamic risk task triggering stronger emotional arousal. Through all three studies, the average effect size for the relationship of assessment with anticipated regret was in the moderate-large range, whereas for risk-taking was in the moderate range. The average effect size for the relationship of locomotion with anticipated regret was in the moderate range, whereas for risk-taking was in the small-moderate range. These results increase our understanding of human behavior under conditions of risk obtaining novel insights into regulatory mode theory and decision science.

Periacetabular osteotomy (PAO) is an effective treatment for symptomatic acetabular dysplasia. However, whether postoperative participation in sports leads to progression of the Kellgren-Lawrence (KL) grade of osteoarthritis (OA) in these patients is unclear. To investigate (1) participation in sports before and after PAO and (2) whether postoperative participation in sports leads to progression of the KL grade. Case-control study; Level of evidence, 3. The authors retrospectively reviewed data on 161 patients (183 hips) who underwent PAO for symptomatic acetabular dysplasia with preoperative KL grade 1 or 2 between 1998 and 2011. The mean age at the time of surgery was 42.0 ± 10.9 years (range, 12-64 years), and the mean follow-up duration was 100 months (range, 13-180 months). Data included participation in sports, the University of California, Los Angeles (UCLA) activity scale score, age at the time of surgery, body mass index, follow-up duration, history of treatment for developmental hip dislocations, Merle d'Aubigné-Postel score, Oxford Hip Score, center-edge angle, and KL grade. Univariate and multivariate analyses were applied to determine which factors were associated with progression to KL grade 3 or 4 after PAO. The number of patients who participated in sports significantly increased from 50 (31.1%) preoperatively to 89 (55.3%) postoperatively. The mean UCLA score significantly increased from 4.7 ± 2.1 preoperatively to 5.5 ± 2.0 postoperatively. The KL grade progressed to grade 3 or 4 in 16 hips, including 4 hips that underwent conversion to total hip arthroplasty. No significant differences were found in postoperative participation in sports (89 hips [53.3%] vs 11 hips [68.8%], respectively; P = .24) and the UCLA score (5.6 ± 2.0 vs 5.1 ± 2.0, respectively; P = .30) between hips with KL grade 1 or 2 and KL grade 3 or 4. A multivariate analysis revealed that no factors, including postoperative participation in sports, were significantly

Substantial progress has been made in the medical management of rheumatoid arthritis (RA) over the past decade with the introduction of biologic therapies, including anti-tumour necrosis factor alpha (anti-TNFα) therapy medications. However, individuals with RA taking anti-TNFα medication continue to experience physical, psychological and functional consequences, which could potentially benefit from rehabilitation. There is evidence that therapeutic exercise should be included as an intervention for people with RA, but to date there is little evidence of the benefits of therapeutic exercise for people with RA on anti-TNFα therapy medication. A protocol for a multicentre randomised controlled three-armed study which aims to examine the effect of dynamic group exercise therapy on land or in water for people with RA taking anti-TNFα therapy medication is described.

Full Text Available Risk-taking amongst veterans has severe consequences, yet few studies have examined factors that may predict risk-taking in help-seeking veteran populations. This paper presents a cross-sectional study involving a random sample of 667 UK help-seeking veterans, investigating the role of demographics, mental health and physical health presentations on the propensity for risk-taking. Out of 403 (73.4% veterans, 350 (86.8% reported risk-taking in the past month. We found that younger age, being in a relationship, probable PTSD, common mental health difficulties and traumatic brain injury were significantly associated with risk-taking. Additionally, a direct association was found between increased risk-taking and PTSD symptom clusters, including higher hyperarousal, elevated negative alterations in mood and cognition. Our findings provide initial evidence for demographic and mental health presentations as predictors of risk-taking in help-seeking veterans. Further research and longitudinal studies are needed to facilitate valid risk assessments, and early intervention for veteran services.

Group members often reason egocentrically, believing that they deserve more than their fair share of group resources. Leading people to consider other members' thoughts and perspectives can reduce these egocentric (self-centered) judgments such that people claim that it is fair for them to take less; however, the consideration of others' thoughts and perspectives actually increases egoistic (selfish) behavior such that people actually take more of available resources. A series of experiments demonstrates this pattern in competitive contexts in which considering others' perspectives activates egoistic theories of their likely behavior, leading people to counter by behaving more egoistically themselves. This reactive egoism is attenuated in cooperative contexts. Discussion focuses on the implications of reactive egoism in social interaction and on strategies for alleviating its potentially deleterious effects.

Full Text Available This study examines willingness to take agricultural insurance by cocoa farmers in Nigeria. A three-stage sampling procedure was used to select 120 cocoa farm households and structured questionnaire was used to elicit data from the respondents. The data were analysed with descriptive statistics and probit regression model. Results showed that 77.5% of the farmers were aware of Agricultural Insurance but only 50% were willing to take it. The average willingness-to-pay (WTP for Agricultural Insurance by the respondents was N11,087.5/ha ($69.85/ha. The significant variables influencing willingness to take agricultural insurance by the farmers were age of household head, educational level, access to extension service and farm income. The study therefore recommends encouraging young well educated people to engage in cocoa farming, overhauling agricultural extension services as well as provision of insurance services to farmers at affordable rate.

2017-06-01

Spinocerebellar ataxia type 6 (SCA6), an autosomal dominant triplet repeat disease, predominantly affects the cerebellum with a late onset and generally good prognosis. Dysphagia is commonly associated with the outcomes of neurodegenerative diseases such as SCA6. Although the characteristics of dysphagia have been rarely reported in SCA6, our previous study indicated that dysphagia is generally milder in SCA6 than in SCA3, another inherited ataxia with multisystem involvement. However, abnormalities in the pharyngeal phase in SCA6 were indistinguishable from those in SCA3, with no explainable reason. To determine the reason, we repeatedly performed videofluoroscopic examinations (VF) in 14 patients with SCA6. The results showed that the gross progression of dysphagia was apparently slow, but four patients had progressive dysphagia at an early disease stage; dysphagia began within 10 years from the onset of ataxia and rapidly progressed. A common clinical feature of the four patients was a significantly older age at the onset of ataxia (74.0 vs. 60.3 years), associated with significantly shorter triplet repeats. This finding surprisingly indicated that patients who had shorter repeats and thereby later onset and potentially better prognoses were at risk for dysphagia-associated problems. Ischemic changes, homozygous mutation, and diabetes mellitus as well as aging might have contributed to the observed progressive dysphagia. We found that conventionally monitored somatosensory evoked potentials at least partly reflected progressive dysphagia. Despite the small study group, our findings suggest that clinicians should carefully monitor dysphagia in patients with SCA6 who are older at disease onset (>60 years).

Targeting the extracellular matrix to disrupt cancer progression

Full Text Available Metastatic complications are responsible for more than 90% of cancer related deaths. The progression from an isolated tumor to disseminated metastatic disease is a multi-step process, with each step involving intricate cross-talk between the cancer cells and their non-cellular surroundings, the extracellular matrix (ECM. Many ECM proteins are significantly de-regulated during the progression of cancer, causing both biochemical and biomechanical changes that together promote the metastatic cascade. In this review, the influence of several ECM proteins on these multiple steps of cancer spread is summarized. In addition, we highlight the promising (pre-clinical data showing benefits of targeting these ECM macromolecules to prevent cancer progression.

Highlights: • Dynamic Bayesian network is used to diagnose and predict accident progress in HTR-PM. • Dynamic Bayesian network model of HTR-PM is built based on detailed system analysis. • LOCA Simulations validate the above model even if part monitors are lost or false. - Abstract: The first high-temperature-reactor pebble-bed demonstration module (HTR-PM) is under construction currently in China. At the same time, development of a system that is used to support nuclear emergency response is in progress. The supporting system is expected to complete two tasks. The first one is diagnostics of the fault in the reactor based on abnormal sensor measurements obtained. The second one is prognostic of the accident progression based on sensor measurements obtained and operator actions. Both tasks will provide valuable guidance for emergency staff to take appropriate protective actions. Traditional method for the two tasks relies heavily on expert judgment, and has been proven to be inappropriate in some cases, such as Three Mile Island accident. To better perform the two tasks, dynamic Bayesian networks (DBN) is introduced in this paper and a pilot study based on the approach is carried out. DBN is advantageous in representing complex dynamic systems and taking full consideration of evidences obtained to perform diagnostics and prognostics. Pearl's loopy belief propagation (LBP) algorithm is recommended for diagnostics and prognostics in DBN. The DBN model of HTR-PM is created based on detailed system analysis and accident progression analysis. A small break loss of coolant accident (SBLOCA) is selected to illustrate the application of the DBN model of HTR-PM in fault diagnostics (FD) and accident progression prognostics (APP). Several advantages of DBN approach compared with other techniques are discussed. The pilot study lays the foundation for developing the nuclear emergency response supporting system (NERSS) for HTR-PM.

2012-01-01

Full Text Available Objective: Iron deficiency is the most common form of malnutrition in developing countries. Iron containing supplements have been used effectively to solve this problem. In children, because of teeth staining after taking iron drops, parents have the idea that iron drops are the cause of tooth decay; therefore, they limit thisvital supplement in their children’s diet. Hereby, we evaluate the histologic effect of iron containing supplements on tooth caries in rice rats with cariogenic or noncariogenic diet.Materials and Methods: Twelve rats were selected and divided into four groups for this interventional experimental study. Four different types of dietary regimens were used for four months; group A, cariogenic diet with iron containing supplements; group B, cariogenic diet without iron containing supplements; groupC, non-cariogenic diet with iron containing supplements; group D, non-cariogenic diet without iron containing supplements. After sacrificing the rats, 20-micron histological sections of their posterior teeth were prepared using the Ground Sectionmethod, then they were studied under polarized light microscopy. In order to compare the progression of caries in different samples, the depth of the lesions in the enamel was measured as three grades I, II and III.Results: The mean grade value of A, B, C and D groups were 1.61, 2.61, 1.37 and 1.80, respectively. Statistical analysis revealed that significantly fewer caries were seen in the group which had received iron containing supplements and cariogenicdiet compared with cariogenic diet without iron supplements (p<0.05.Conclusion: Ferrous sulfate reduces the progression of dental caries in the cariogenic dietary regimen.

Take-off aerodynamics in ski jumping.

Virmavirta, M; Kivekäs, J; Komi, P V

2001-04-01

The effect of aerodynamic forces on the force-time characteristics of the simulated ski jumping take-off was examined in a wind tunnel. Vertical and horizontal ground reaction forces were recorded with a force plate installed under the wind tunnel floor. The jumpers performed take-offs in non-wind conditions and in various wind conditions (21-33 m s(-1)). EMGs of the important take-off muscles were recorded from one jumper. The dramatic decrease in take-off time found in all jumpers can be considered as the result of the influence of aerodynamic lift. The loss in impulse due to the shorter force production time with the same take-off force is compensated with the increase in lift force, resulting in a higher vertical velocity (V(v)) than is expected from the conventional calculation of V(v) from the force impulse. The wind conditions emphasized the explosiveness of the ski jumping take-off. The aerodynamic lift and drag forces which characterize the aerodynamic quality of the initial take-off position (static in-run position) varied widely even between the examined elite ski jumpers. According to the computer simulation these differences can decisively affect jumping distance. The proper utilization of the prevailing aerodynamic forces before and during take-off is a very important prerequisite for achieving a good flight position.

Trials of anti-inflammatory therapies in non-relapsing progressive multiple sclerosis (MS) have been stubbornly negative except recently for an anti-CD20 therapy in primary progressive MS and a S1P modulator siponimod in secondary progressive MS. We argue that this might be because trials have been too short and have focused on assessing neuronal pathways, with insufficient reserve capacity, as the core component of the primary outcome. Delayed neuroaxonal degeneration primed by prior inflammation is not expected to respond to disease-modifying therapies targeting MS-specific mechanisms. However, anti-inflammatory therapies may modify these damaged pathways, but with a therapeutic lag that may take years to manifest. Based on these observations we propose that clinically apparent neurodegenerative components of progressive MS may occur in a length-dependent manner and asynchronously. If this hypothesis is confirmed it may have major implications for the future design of progressive MS trials. Copyright © 2016 Elsevier B.V. All rights reserved.

Vladimír Hojka

2016-06-01

Full Text Available Background: Many sport activities are a sequence of jumps (running, jumping, hurdling etc.. Each jump flight phase is the result of the execution of the previous support phase. Objective: The goal of the research was to identify differences in adjustment of the support lower limb and differences in take-off kinematics in specific take-off movement task. Methods: 14 male athletes (22.6 ± 4.4 years; 182.4 ± 5.3 cm; 74.7 ± 6.2 kg took part in a laboratory experiment. Each athlete performed five different take-off movements (running, acceleration running - second step, long jump take-off, high jump take-off and take-off to the hurdle. System Qualisys was used to analyze the kinematics of the support limb. Dynamics of the support phase was monitored via force plate. ANOVA and Bonferroni post-hoc test were used to measure the significance of the differences between different take off tasks. Results: Dynamic characteristic showed significant differences in take-off (p < .001. This variability is caused by differences in kinematic parameters at the instant of touch-down, minimum joint angles and take-off. The most important finding was different variability in range of motion in eccentric or concentric phases of each jump. Vertically orientated jumps are terminated in a higher degree of extension. Horizontal take-off types are characterized by the highest ranges of motion especially in the ankle joint. Conclusions: The support lower limb compliance is adjusted to the required task, which is related to lower limb kinematics during the support phase. High range of motion in each joint refers to more compliant adjustment of the joint.

Progress report of a research program in experimental high energy physics

International Nuclear Information System (INIS)

Widgoff, M.

1991-01-01

The LVD Collaboration has made major progress during the past year in constructing the basic modules of the detector and installing them in five-tower LVD structure. Each of these modules consists of a portatank containing eight liquid scintillation counters (each 1.0m x 1.0m x 1.5m, viewed by three photomultipliers) totalling 9.6 tons of liquid scintillator and 6.7 tons of steel. Each portatank is covered on its bottom and one side by two layers of limited streamer tubes which form the tracking system of the detector. About half of the first tower has now been installed and initial data-taking with the entire tower is expected to being during the Fall of 1991. Data acquisition hardware and software are in place for this. The data-taking run of FNAL Experiment E782, a study of the interactions of 200 GeV muons in a hybrid system with the Tohoku Freon bubble chamber as visible target, was completed in August 1990. Film analysis is now in progress. The results will be readily comparable to those obtained in FNAL Experiment E745, a study of the interactions of muon neutrinos in a similar system. The film analysis of E745 has been completed, and some preliminary results are presented on the production of strange particles, based on the combined data of both the 1985 and 1987 runs of this experiment

Ghrelin and cancer progression.

Lin, Tsung-Chieh; Hsiao, Michael

2017-08-01

Ghrelin is a small peptide with 28 amino acids, and has been characterized as the ligand of the growth hormone secretagogue receptor (GHSR). In addition to its original function in stimulating pituitary growth hormone release, ghrelin is multifunctional and plays a role in the regulation of energy balance, gastric acid release, appetite, insulin secretion, gastric motility and the turnover of gastric and intestinal mucosa. The discovery of ghrelin and GHSR expression beyond normal tissues suggests its role other than physiological function. Emerging evidences have revealed ghrelin's function in regulating several processes related to cancer progression, especially in metastasis and proliferation. We further show the relative GHRL and GHSR expression in pan-cancers from The Cancer Genome Atlas (TCGA), suggesting the potential pathological role of the axis in cancers. This review focuses on ghrelin's biological function in cancer progression, and reveals its clinical significance especially the impact on cancer patient outcome. Copyright © 2017 The Authors.

The colloquium organised by the Association of Energy Economists dealing with the theme 'Technical progress faced with the challenges of the energy sector in the future' takes place against a backdrop of ever-increasing initiatives in this field, for example at the World Energy Council or the International Energy Agency Faith in technical progress is widespread but should be supported by studies without any preconceived ideas. Research and development efforts must be fully supported, and in a climate of opening markets and liberalization the public authorities have a major role to pay. Historically, the markets have always been able to meet new needs thanks to technology, but the ambitious targets that the international community has set itself regarding the emission of greenhouse gases imply technical improvements and major investments.

Struzik, Artur; Zawadzki, Jerzy

2013-01-01

With respect to cyclic movements such as human gait, running or hopping, leg stiffness is a little variable parameter. The aim of this study was to investigate changes in leg stiffness during the phase of countermovement and take-off when performing a single maximum counter-movement jump. Kistler force plates and a BTS SMART system for comprehensive motion analysis were employed in the study. The study covered a group of 12 athletes from university basketball teams. Leg stiffness was calculated in those parts of countermovement and take-off phases where its level is relatively constant and the relationship F(Δl) is similar to linear one. Mean total stiffness (±SD) in both legs in the countermovement phase amounted to 6.5 ± 1.5 kN/m, whereas during the take-off phase this value was 6.9 ± 1 kN/m. No statistically significant differences were found between leg stiffness during the countermovement phase and takeoff phase in the study group at the level of significance set at α = 0.05. This suggests that the leg stiffness in phase of countermovement and phase of take-off are much similar to each other, despite different function of both phases. Similar to cyclic movements, leg stiffness turned out relatively constant when performing a single vertical jump. There are also reported statistically significant correlations between body mass, body height, length of lower limbs and leg stiffness. The stiffness analysed by the authors should be understood as quasi-stiffness because the measurements of ΔF(Δl) were made during transient states where inertia and dumping forces are likely to affect the final result.

Full Text Available The technological progress, digitization and the explosion of information significantly change how individuals, the business environment, and society act, develop and add value. New, interdisciplinary approaches, constantly adapted and sustainable both at the micro and the macro levels are required. Within a company, change management is a systematic element of the strategic business process and involves the early identification of the opportunity of the employees’ development, courage, commitment and flexibility; under no circumstances should it be seen as a risk and instability factor, as it may be considered in the early stages. The example presented in this article proves that the openness to change and continuous improvement develops advantages, optimizes processes and sustains long-term progress.

Full Text Available Simron Singh,1 Xufang Wang,2 Calvin HL Law1 1Sunnybrook Odette Cancer Center, University of Toronto, Toronto, ON, Canada; 2Novartis Oncology, Florham Park, NJ, USA Abstract: Overall survival can be difficult to determine for slowly progressing malignancies, such as neuroendocrine tumors. We investigated whether time to disease progression is positively associated with overall survival in patients with such tumors. A literature review identified 22 clinical trials in patients with neuroendocrine tumors that reported survival probabilities for both time to disease progression (progression-free survival and time to progression and overall survival. Associations between median time to disease progression and median overall survival and between treatment effects on time to disease progression and treatment effects on overall survival were analyzed using weighted least-squares regression. Median time to disease progression was significantly associated with median overall survival (coefficient 0.595; P=0.022. In the seven randomized studies identified, the risk reduction for time to disease progression was positively associated with the risk reduction for overall survival (coefficient on −ln[HR] 0.151; 95% confidence interval −0.843, 1.145; P=0.713. The significant association between median time to disease progression and median overall survival supports the assertion that time to disease progression is an alternative end point to overall survival in patients with neuroendocrine tumors. An apparent albeit not significant trend correlates treatment effects on time to disease progression and treatment effects on overall survival. Informal surveys of physicians’ perceptions are consistent with these concepts, although additional randomized trials are needed. Keywords: neuroendocrine tumors, progression-free survival, disease progression, mortality

Economic inequality increases risk taking.

Rising income inequality is a global trend. Increased income inequality has been associated with higher rates of crime, greater consumer debt, and poorer health outcomes. The mechanisms linking inequality to poor outcomes among individuals are poorly understood. This research tested a behavioral account linking inequality to individual decision making. In three experiments ( n = 811), we found that higher inequality in the outcomes of an economic game led participants to take greater risks to try to achieve higher outcomes. This effect of unequal distributions on risk taking was driven by upward social comparisons. Next, we estimated economic risk taking in daily life using large-scale data from internet searches. Risk taking was higher in states with greater income inequality, an effect driven by inequality at the upper end of the income distribution. Results suggest that inequality may promote poor outcomes, in part, by increasing risky behavior.

The mood disorders of depression are associated with abnormalities of brain structure and function, and exploring their pathological mechanism has important significance for the choice of treatment and the curative effect evaluation. In recent years, the research of MRI on brain structure and function of depression has made great progress, especially in functional magnetic resonance imaging (fMRI). fMRI can detect the functional change in real time, and also can display the activity of brain and changes in the nerve pathways in patients with depression. This article summarizes the present research situation and progress of MRI in the diagnosis of depression. (authors)

Factors Affecting Career Progress of MBA Students

Full Text Available This paper explored the factors that affect career progress of students in the MBA program of the University of the Philippines.To understand career progression, four measures of career progress were used in this study, namely: number of promotions, number of years in between promotions, total cash compensation, and number of administrative levels from the company president. On the other hand, the factors used to explain career progess included human capital, organizational, interpersonal and demographic variables.The results showed that the different measures of career progress had distinct determinants implying different dynamics. It appeared that measures of career progress that are sensitive to the value employers attach to the individual (Whitely, Dougherty, & Dreher, 1991 such as total compensation, total number of promotion and years per promotion were related with human capital factors such as work experience and number of companies worked for. On the other hand, measures that relate to centrality if the position, in which market forces have less impact, were associated with organizational variables such as organization size and the demographic variable gender.While gender did not explain variation in total compensation, number of promotions and number of uears between promotions, these null results are important for two reasons. First, it implies that the female MBA students were at par with their male counterparts as fas as these measures of career progress are concerned. Second, it challenges the generalizability of the finding of gender segregation at the organizational level-where men receive significantly higher wages that women-which is a common finding among studies done in the United States. The results using the MBA students as sample show that income and promotion parity may indeed be achievable and this brings hope to women in general.However, the statistical significance of gender in explaining career progress as centrality

Concerning damage pattern, the most critical sector is observed to shift leeward with increasing wave period. Taking angles...... over the roundhead is developed. Thus the formula also considers the shifting of the critical sector due to increasing wave period which existing formulae do not include. Finally, analysing the damage produced by double peaked spectra, it is shown that the armour may be designed by the formula when...

Motor and verbal perspective taking in children with Autism Spectrum Disorder: Changes in social interaction with people and tools.

Studenka, Breanna E; Gillam, Sandra L; Hartzheim, Daphne; Gillam, Ronald B

2017-07-01

Children with Autism Spectrum Disorder (ASD) have difficulty communicating with others nonverbally, via mechanisms such as hand gestures, eye contact and facial expression. Individuals with ASD also have marked deficits in planning future actions (Hughes, 1996), which might contribute to impairments in non-verbal communication. Perspective taking is typically assessed using verbal scenarios whereby the participant imagines how an actor would interact in a social situation (e.g., Sally Anne task; Baron-Cohen, Leslie, & Frith, 1985). The current project evaluated motor perspective taking in five children with ASD (8-11 years old) as they participated in a narrative intervention program over the course of about 16 weeks. The goal of the motor perspective-taking task was to facilitate the action of an experimenter either hammering with a tool or putting it away. Initially, children with ASD facilitated the experimenter's action less than neurotypical control children. As the narrative intervention progressed, children with ASD exhibited increased motor facilitation that paralleled their increased use of mental state and causal language, indicating a link between verbal and motor perspective taking. Motoric perspective taking provides an additional way to assess understanding and communication in children with ASD and may be a valuable tool for both early assessment and diagnosis of children with ASD.

Take-off mechanics in hummingbirds (Trochilidae).

2004-03-01

Initiating flight is challenging, and considerable effort has focused on understanding the energetics and aerodynamics of take-off for both machines and animals. For animal flight, the available evidence suggests that birds maximize their initial flight velocity using leg thrust rather than wing flapping. The smallest birds, hummingbirds (Order Apodiformes), are unique in their ability to perform sustained hovering but have proportionally small hindlimbs that could hinder generation of high leg thrust. Understanding the take-off flight of hummingbirds can provide novel insight into the take-off mechanics that will be required for micro-air vehicles. During take-off by hummingbirds, we measured hindlimb forces on a perch mounted with strain gauges and filmed wingbeat kinematics with high-speed video. Whereas other birds obtain 80-90% of their initial flight velocity using leg thrust, the leg contribution in hummingbirds was 59% during autonomous take-off. Unlike other species, hummingbirds beat their wings several times as they thrust using their hindlimbs. In a phylogenetic context, our results show that reduced body and hindlimb size in hummingbirds limits their peak acceleration during leg thrust and, ultimately, their take-off velocity. Previously, the influence of motivational state on take-off flight performance has not been investigated for any one organism. We studied the full range of motivational states by testing performance as the birds took off: (1) to initiate flight autonomously, (2) to escape a startling stimulus or (3) to aggressively chase a conspecific away from a feeder. Motivation affected performance. Escape and aggressive take-off featured decreased hindlimb contribution (46% and 47%, respectively) and increased flight velocity. When escaping, hummingbirds foreshortened their body movement prior to onset of leg thrust and began beating their wings earlier and at higher frequency. Thus, hummingbirds are capable of modulating their leg and

Taking blame for another person's misconduct may occur at relatively high rates for less serious crimes. The authors examined individual differences and situational factors related to this phenomenon by surveying college students (n = 213) and men enrolled in substance abuse treatment programs (n = 42). Among college students, conscientiousness and delinquency predicted their likelihood of being in a situation in which it was possible to take the blame for another person's misconduct. Situational factors, including the relationship with the perpetrator, the seriousness of the offense, feelings of responsibility for the offense, and differential consequences between the offender and the blame taker, were associated with college students' decisions to take the blame. Among substance abuse treatment participants, individuals who took the blame for another person's misconduct were more extraverted, reported feeling more loyalty toward the true perpetrator, and indicated more incentives to take the blame than individuals who did not take the blame. Links between theories of helping behavior and situational factors that predict blame taking are discussed. Copyright © 2015 John Wiley & Sons, Ltd.

Is Risk Taking Used as a Cue in Mate Choice?

Full Text Available More frequent risk taking among young men than women has been explained as a sexually selected trait, perhaps advertising male quality. We investigated this hypothesis in three studies. (1 Young men and women rated how attractive they would find it if a potential partner took various specific risks. A domain-specific risk inventory allowed us to distinguish whether risk taking is attractive generally or only in certain domains. Both sexes reported social and recreational risk taking as attractive (the latter not always significantly so, but other domains of risk taking as unattractive (ethics, gambling, and health or neutral (investment. The sexes differed markedly little. Parallel studies in Germany and the United States yielded very similar results. (2 We asked subjects to predict how attractive the other sex would find it if the subject performed each risky behavior. Both sexes were rather accurate (which could be merely because they assume that the other sex feels as they do and sex differences in attractive risk taking are not explicable by sex differences either in attraction or in beliefs about what others find attractive. However, our data could explain why unattractive risks are more often taken by men than women (men slightly underestimated the degree of unattractiveness of such risks, whereas U.S. women overestimated it, perhaps because they themselves found such risk taking more unattractive than did U.S. men. (3 Both members of 25 couples reported their likelihood of engaging in specific risky behaviors, their perception of these risks, and how attractive they would have found these behaviors in their partner. One hypothesis was that, for instance, a woman afraid of heights would be particularly impressed by a man oblivious to such risks. Instead we found positive assortment for risk taking, which might be explained by a greater likelihood of encountering people with similar risk attitudes (e.g. members of the same clubs or a

In the formative period of the courses taken in medical specializations, new and greater responsibilities are accepted by physicians in personal and academic spheres. The interaction of several factors that encompass the practice of these physicians could surpass their capacity to cope, causing on these professionals a high level of stress and professional exhaustion, which will affect their academic development. The objective of this research was to establish if the occupational stress of these medical residents affects their academic progress. We administered the Spanish version of the Maslach Burnout Inventory (MBI) to 52 residents of three specializations in Oncology (Medical Oncology, Surgical Oncology, and Radio-Oncology). These residents accepted voluntarily at the same time of their third cognitive exam. The prevalence of burnout syndrome was 13.5 %, with a high frequency among medical residents of first degree. Medical Oncology residents showed a higher emotional exhaustion and lower personal fulfillment. Considering the three specializations, the academic progress was higher in the third year, with a significant difference to Surgical Oncology and Medical Oncology (p = 0.026 and 0.015, respectively). No significant difference was found between burnout syndrome, academic progress and sociodemographic characteristics. The presence of burnout syndrome does not affect the academic progress of Oncology medical residents.

When Progressive Disease Does Not Mean Treatment Failure: Reconsidering the Criteria for Progression

Science.gov (United States)

2012-01-01

Although progression-based endpoints, such as progression-free survival, are often key clinical trial endpoints for anticancer agents, the clinical meaning of “objective progression” is much less certain. As scrutiny of progression-based endpoints in clinical trials increases, it should be remembered that the Response Evaluation Criteria In Solid Tumors (RECIST) progression criteria were not developed as a surrogate for survival. Now that progression-free survival has come to be an increasingly important trial endpoint, the criteria that define progression deserve critical evaluation to determine whether alternate definitions of progression might facilitate the development of stronger surrogate endpoints and more meaningful trial results. In this commentary, we review the genesis of the criteria for progression, highlight recent data that question their value as a marker of treatment failure, and advocate for several research strategies that could lay the groundwork for a clinically validated definition of disease progression in solid tumor oncology.

Nuclear receptor coactivator 5 (NCOA5) is known to modulate ERα-mediated transcription and has been found to be involved in the progression of several malignancies. However, the potential correlation between NCOA5 and clinical outcome in patients with luminal breast cancer remains unknown. In the present study, we demonstrated that NCOA5 was significantly up-regulated in luminal breast cancer tissues compared with adjacent non-cancerous tissues both in validated cohort and TCGA cohort. Moreover, Kaplan-Meier analysis indicated that patients with high NOCA5 expression had significantly lower overall survival (P = 0.021). Cox regression analysis indicated that the high NOCA5 expression was independent high risk factor as well as old age (>60) and HER-2 expression (P = 0.039; P = 0.003; P = 0.005; respectively). This study provides new insights and evidences that NOCA5 over-expression was significantly correlated with progression and prognosis in luminal breast cancer. However, the precise cellular mechanisms for NOCA5 in luminal breast cancer need to be further explored. - Highlights: • NCOA5 is significantly over-expressed in human luminal breast cancer tissues. • NOCA5 was involved in the progression of luminal breast cancer. • NCOA5 can predict the progression of luminal breast cancer.

Young Children’s Risk-Taking: Mothers’ Authoritarian Parenting Predicts Risk-Taking by Daughters but Not Sons

We investigated how mothers’ parenting behaviors and personal characteristics were related to risk-taking by young children. We tested contrasting predictions from evolutionary and social role theories with the former predicting higher risk-taking by boys compared to girls and the latter predicting that mothers would influence children’s gender role development with risk-taking occurring more in children parented with higher levels of harshness (i.e., authoritarian parenting style). In our st...

Previous research has demonstrated that college students who view TakeCARE, a video bystander program designed to encourage students to take action to prevent sexual and relationship violence (i.e., bystander behavior), display more bystander behavior relative to students who view a control video. The current study aimed to replicate and extend these findings by testing two different methods of administering TakeCARE and examining moderators of TakeCARE's effects on bystander behavior. Students at four universities ( n = 557) were randomly assigned to one of three conditions: (a) view TakeCARE in a monitored computer lab, (b) view TakeCARE at their own convenience after receiving an email link to the video, or (c) view a video about study skills (control group). Participants completed measures of bystander behavior at baseline and at a 1-month follow-up. Participants in both TakeCARE conditions reported more bystander behavior at follow-up assessments, compared with participants in the control condition. The beneficial effect of TakeCARE did not differ significantly across administration methods. However, the effects of TakeCARE on bystander behavior were moderated by students' perceptions of campus responsiveness to sexual violence, with more potent effects when students perceived their institution as responsive to reports of sexual violence.

Contemporary Visions of Progress in Ecology and Thoughts for the Future

Full Text Available Although ecological research is progressing rapidly, the answers to certain key questions continue to elude us. This paper considers several of the contemporary challenges facing ecology. (1 Terminology is voluminous and often poorly defined, resulting in inefficient communication. (2 The concept of scale affects our inferences about system structure and function, requiring us to continue an almost heuristic investigation of breaks, domains, and integration. New tools that more explicitly incorporate scalar issues will need to be developed for progress to take place in the field of ecology. (3 Increasingly, it is expected that applied questions will be solved in less than a year. This demand for solutions from ecologists often produces short-term and inadequate responses. (4 How can ecologists improve communication between subdisciplines, with undergraduate students, and with the public? How will ecology be done in the future, and by whom? We provide some background to these observations and questions, and offer some potential solutions from the viewpoint of young practicing ecologists.

The increasingly stringent safety requirements of workers and the general public in the face of occupational and in particular nuclear risks call for continual improvements in radiation protection techniques. The Institute of Protection and Nuclear Safety (IPSN), especially the Technical Protection Services belonging to the Protection Department, and also the various radiation protection services of the French Atomic Energy Commission's nuclear centres and Electricite de France (EDF) are carrying out substantial research and development programmes on the subject. For this reason, IPSN organized a specialists' meeting to take stock of the efforts being made and to try to identify what steps seem most promising or should have priority at the national level. The authors summarize the presentations and discussions on three topics: (1) Progress in the analysis of the mechanism of exposure of workers; (2) Progress achieved from the radiation protection standpoint in the field of facility design and instrumentation; and (3) Application of the optimization principle

Full Text Available Objective. To examine risk taking behaviours associated with alcohol consumption amongst UK undergraduate students. Design and Methods. A cross-sectional web survey was used to assess attitudes and health behaviours. The survey included the Alcohol Use Disorders Identification Test (AUDIT. Students were also asked about why they drank alcohol; about their preferred alcoholic beverage; and if they had experienced any consequences associated with drinking alcohol as well as questions relating to sexual risk taking, drug use, and smoking. Results. 2779 (65% female; 84% White British students completed some part of the survey. Of these, 98% (n=2711 completed the AUDIT. Of the 92% that drank 66% (n=1,643 were categorised as being AUDIT positive. 8% (n=224 were categorised as probably alcohol dependent. Higher AUDIT scores were significantly associated with negative consequences such as unplanned sexual activity, physical injuries, and arguments. Other risk taking behaviours such as drug use and smoking were also found to be positively correlated with higher AUDIT scores; drug use; and smoking. Conclusions. The results from this study provide insight into students’ alcohol consumption and associated risk taking. University policies need to protect students’ overall health and wellbeing to ensure academic potential is maximised.

Phytoalexins: Current Progress and Future Prospects

Directory of Open Access Journals (Sweden)

Philippe Jeandet

2015-02-01

Full Text Available Phytoalexins are low molecular weight antimicrobial compounds that are produced by plants as a response to biotic and abiotic stresses. As such they take part in an intricate defense system which enables plants to control invading microorganisms. In the 1950s, research on phytoalexins started with progress in their biochemistry and bio-organic chemistry, resulting in the determination of their structure, their biological activity, as well as mechanisms of their synthesis and catabolism by microorganisms. Elucidation of the biosynthesis of numerous phytoalexins also permitted the use of molecular biology tools for the exploration of the genes encoding enzymes of their synthesis pathways and their regulators. This has led to potential applications for increasing plant resistance to diseases. Phytoalexins display an enormous diversity belonging to various chemical families such as for instance, phenolics, terpenoids, furanoacetylenes, steroid glycoalkaloids, sulfur-containing compounds and indoles.[...

2013-02-01

Full Text Available During the past few years, there have been tremendous works on detecting the relationship between banks performance and the number of seats on board of directors. Board of directors of banks is responsible for shareholders ownership’s interest. In this study, governance and ownership characteristics affecting risk appetite on some private banks listed in Tehran Stock Exchange is studied. The study investigates 12 private banks for a period 2005-2011 based on the implementation of some regression analysis using panel data. The results indicate that the effect of five major shareholders on risk-taking is positive and significant. The effect of institutional ownership on risk-taking is negative and significant. Effects of other variables, including the percentage of ownership concentration, return on assets and the logarithm of cash from operations (CFO on risk-taking of the private banks are not significant. The effects of board size, reliance on debt and log of assets on risk-taking are significantly negative among private banks in Iran. These results indicate that shareholders that are institutional investors play a key role in monitoring managers.

Epidemiological data indicate that risk behaviors are among the leading causes of adolescent morbidity and mortality worldwide. Consistent with this, laboratory-based studies of age differences in risk behavior allude to a peak in adolescence, suggesting that adolescents demonstrate a heightened propensity, or inherent inclination, to take risks. Unlike epidemiological reports, studies of risk taking propensity have been limited to Western samples, leaving questions about the extent to which heightened risk taking propensity is an inherent or culturally constructed aspect of adolescence. In the present study, age patterns in risk-taking propensity (using two laboratory tasks: the Stoplight and the BART) and real-world risk taking (using self-reports of health and antisocial risk taking) were examined in a sample of 5227 individuals (50.7% female) ages 10-30 (M = 17.05 years, SD = 5.91) from 11 Western and non-Western countries (China, Colombia, Cyprus, India, Italy, Jordan, Kenya, the Philippines, Sweden, Thailand, and the US). Two hypotheses were tested: (1) risk taking follows an inverted-U pattern across age groups, peaking earlier on measures of risk taking propensity than on measures of real-world risk taking, and (2) age patterns in risk taking propensity are more consistent across countries than age patterns in real-world risk taking. Overall, risk taking followed the hypothesized inverted-U pattern across age groups, with health risk taking evincing the latest peak. Age patterns in risk taking propensity were more consistent across countries than age patterns in real-world risk taking. Results suggest that although the association between age and risk taking is sensitive to measurement and culture, around the world, risk taking is generally highest among late adolescents.

2014-01-01

Cervical spondylolysis is a rare condition defined as a corticated cleft at the pars interarticularis in the cervical spine. This is the case of C2 spondylolysis demonstrating progressive significant instability, which was successfully treated by anterior cervical discectomy and fusion (ACDF) with cervical anterior plate. We describe a 20-year-old female with C2 spondylolysis presenting with progressive worsening of neck pain associated with progressive instability at the C2/3 segment. The progression of instability was well-documented on flexion-extension cervical spine x-rays. She was successfully treated by C2/3 ACDF with anterior cervical plate. Her preoperative significant neck pain resolved immediately after the surgical intervention. She was completely free from neurological symptoms at 1-year postoperative follow-up. We also review the literature and discuss 24 reported cases with C2 spondylolysis. When planning treatment, we should make sure to differentiate this pathology from acute traumatic fracture, which is a hangman's fracture. Assessment of C2/3 instability associated with neurological deficits is extremely important to consider management properly. C2/3 ACDF with cervical plate is biomechanically viable, less invasive, and provides adequate surgical stabilization for unstable C2 spondylolysis.

Creatinine measurements often yielded false estimates of progression in chronic renal failure

International Nuclear Information System (INIS)

Walser, M.; Drew, H.H.; LaFrance, N.D.

1988-01-01

In 9 of 22 observation periods (lasting an average of 15 months) in 17 patients with moderate to severe chronic renal failure (GFR 4 to 23 ml/min), rates of progression as estimated from the linear regression on time of 24-hour creatinine clearance (b1) differed significantly from rates of progression as estimated from the regression on time of urinary clearance of 99mTc-DTPA (b2), during all or part of the period of observation. b1 exceeded b2 in four cases and was less than b2 in the other five. Thus there were gradual changes in the fractional tubular secretion of creatinine in individual patients, in both directions. Owing to these changes, measurements of creatinine clearance gave erroneous impressions of the rate or existence of progression during all or a portion of the period of observation in nearly half of these patients. In the 22 studies as a group, using the entire periods of observation, b1 indicated significantly more rapid progression (by 0.18 +/- 0.06 ml/min/month, P less than 0.01) than did b2, and had a significantly greater variance. Measurements of progression based on the rate of change of reciprocal plasma creatinine (multiplied by an average rate of urinary creatinine excretion in each study) were equally misleading, even though less variable. We conclude that sequential creatinine measurements are often misleading as measures of progression and should, when feasible, be replaced by urinary clearance of isotopes in following patients with chronic renal failure

To explore the effects of dyslexia on the practice and career progression of UK registered nurses (RN). Literature suggests dyslexia can have a negative impact in the workplace and may pose particular difficulties for nurses, where accuracy in information processing activities is essential for practice. A questionnaire was used to survey RNs with dyslexia (n = 116) and results analysed using content analysis. Dyslexia provided a challenge to the everyday work of RNs, which was often met successfully using a range of individualized strategies. Career progression was achievable but compared with peers, was perceived to take longer. Disclosure of dyslexia to work-colleagues was selective and dependent on the perceived benefits. Informal support mechanisms were commonly utilized with formal management support less well defined. Dyslexia appears to have a negative impact on working practices and career progression, but remains a poorly understood and often hidden disability.

Although recommended approaches to CKD management are achieved less often in Hispanics than in non-Hispanics, whether long-term outcomes differ between these groups is unclear. In a prospective longitudinal analysis of participants enrolled into the Chronic Renal Insufficiency Cohort (CRIC) and Hispanic-CRIC Studies, we used Cox proportional hazards models to determine the association between race/ethnicity, CKD progression (50% eGFR loss or incident ESRD), incident ESRD, and all-cause mortality, and linear mixed-effects models to assess differences in eGFR slope. Among 3785 participants, 13% were Hispanic, 43% were non-Hispanic white (NHW), and 44% were non-Hispanic black (NHB). Over a median follow-up of 5.1 years for Hispanics and 6.8 years for non-Hispanics, 27.6% of all participants had CKD progression, 21.3% reached incident ESRD, and 18.3% died. Hispanics had significantly higher rates of CKD progression, incident ESRD, and mean annual decline in eGFR than did NHW (P<0.05) but not NHB. Hispanics had a mortality rate similar to that of NHW but lower than that of NHB (P<0.05). In adjusted analyses, the risk of CKD progression did not differ between Hispanics and NHW or NHB. However, among nondiabetic participants, compared with NHB, Hispanics had a lower risk of CKD progression (hazard ratio, 0.61; 95% confidence interval, 0.39 to 0.95) and incident ESRD (hazard ratio, 0.50; 95% confidence interval, 0.30 to 0.84). At higher levels of urine protein, Hispanics had a significantly lower risk of mortality than did non-Hispanics (P<0.05). Thus, important differences in CKD progression and mortality exist between Hispanics and non-Hispanics and may be affected by proteinuria and diabetes.

Predictors of disease progression in HIV infection: a review

Directory of Open Access Journals (Sweden)

2007-05-01

Full Text Available Abstract During the extended clinically latent period associated with Human Immunodeficiency Virus (HIV infection the virus itself is far from latent. This phase of infection generally comes to an end with the development of symptomatic illness. Understanding the factors affecting disease progression can aid treatment commencement and therapeutic monitoring decisions. An example of this is the clear utility of CD4+ T-cell count and HIV-RNA for disease stage and progression assessment. Elements of the immune response such as the diversity of HIV-specific cytotoxic lymphocyte responses and cell-surface CD38 expression correlate significantly with the control of viral replication. However, the relationship between soluble markers of immune activation and disease progression remains inconclusive. In patients on treatment, sustained virological rebound to >10 000 copies/mL is associated with poor clinical outcome. However, the same is not true of transient elevations of HIV RNA (blips. Another virological factor, drug resistance, is becoming a growing problem around the globe and monitoring must play a part in the surveillance and control of the epidemic worldwide. The links between chemokine receptor tropism and rate of disease progression remain uncertain and the clinical utility of monitoring viral strain is yet to be determined. The large number of confounding factors has made investigation of the roles of race and viral subtype difficult, and further research is needed to elucidate their significance. Host factors such as age, HLA and CYP polymorphisms and psychosocial factors remain important, though often unalterable, predictors of disease progression. Although gender and mode of transmission have a lesser role in disease progression, they may impact other markers such as viral load. Finally, readily measurable markers of disease such as total lymphocyte count, haemoglobin, body mass index and delayed type hypersensitivity may come into favour

Tintinnida are abundant microzooplankton found in all of the world's oceans, and important components of the marine food web as predators, prey, and as regenerators of nutrients. The agglutinated forms take on added importance in coastal waters. Representatives of this group have the unique ability among ciliates to pick up particles from the environment and incorporate them into the lorica. The ecological significance of the phenomenon lies in: it is a pathway whereby radionuclides, metals and other toxic substance can be biologically concentrated and transferred from sediments and the water column to the biota; from the viewpoint of microzooplankton as indicators of environmental perturbations, pollution, or water mass movements, it is important to determine whether minerals accumulated on the lorica can serve as a guide to the site where they originate. Results are reported from studies in progress on the types of mineral matter accumulated by tintinnids

Interactions of flow-dominated plasmas with other plasmas, neutral gases, magnetic fields, solids etc., take place with sufficient velocity that kinetic energy dominates the dynamics of the interaction (as opposed to magnetic or thermal energy, which dominates in most laboratory plasma experiments). Building upon progress made by the Magnetized Shock Experiment (MSX) at LANL, we are developing the experimental and modeling capability to increase our ultimate attainable plasma velocities well in excess of 1000 km/s. Ongoing work includes designing new pulsed power switches, triggering, and inductive adder topologies; development of novel high-speed optical diagnostics; and exploration of new numerical techniques to specifically model the unique physics of translating/stagnating flow-dominated plasmas. Furthering our understanding of the physical mechanisms of energy conversion from kinetic to other forms, such as thermal energy, non-thermal tails/accelerated populations, enhanced magnetic fields, and radiation (both continuum and line), has wide-ranging significance in basic plasma science, astrophysics, and plasma technology applications such as inertial confinement fusion and intense radiation sources.

The fraction of inspired O2 (FiO2 and partial pressure of inspired O2 (PiO2 were 0.209 and 133.1 ± 0.3 mmHg for NBR and 0.141 ± 0.004 and 90.0 ± 0.4 mmHg for both hypoxic variants (HBR and HAmb; ~4000 m simulated altitude, respectively. A number of parameters linked to intestinal environment such as defecation frequency, intestinal electrical conductivity (IEC, sterol and polyphenol content and diversity, indole, aromaticity and spectral characteristics of dissolved organic matter (DOM were measured (64 variables. The structure and diversity of bacterial microbial community was assessed using 16S rRNA amplicon sequencing. Inactivity negatively affected frequency of defecation and in combination with hypoxia increased IEC (p < 0.05. In contrast, sterol and polyphenol diversity and content, various characteristics of DOM and aromatic compounds, the structure and diversity of bacterial microbial community were not significantly affected over time. A new in-house PlanHab database was established to integrate all measured variables on host physiology, diet, experiment, immune and metabolic markers (n = 231. The observed progressive decrease in defecation frequency and concomitant increase in IEC suggested that the transition from healthy physiological state towards the developed symptoms of low magnitude obesity-related syndromes was dose dependent on the extent of time spent in inactivity and preceded or took place in absence of significant rearrangements in bacterial microbial community.

Night Owl Women are Similar to Men in Their Relationship Orientation, Risk-taking Propensities, and Cortisol Levels: Implications for the Adaptive Significance and Evolution of Eveningness

Directory of Open Access Journals (Sweden)

Full Text Available Individual differences in morningness/eveningness are relatively stable over time and, in part, genetically based. The night-owl pattern is more prevalent in men than in women, particularly after puberty and before women reach menopause. It has been suggested that eveningness evolved relatively recently in human evolutionary history and that this trait may be advantageous to individuals pursuing short-term mating strategies. Consistent with this hypothesis, eveningness is associated with extraversion, novelty-seeking, and in males, with a higher number of sexual partners. In this study, I investigated whether eveningness is associated with short-term relationship orientation, higher risk-taking, and higher testosterone or cortisol. Both female and male night-owls were more likely to be single than in long-term relationships than early morning individuals. Eveningness was associated with higher risk-taking in women but not in men; this association was not testosterone-dependent but mediated by cortisol. Female night-owls had average cortisol profiles and risk-taking tendencies more similar to those of males than to those of early-morning females. Taken together, these findings provide some support to the hypothesis that eveningness is associated with psychological and behavioral traits that are instrumental in short-term mating strategies, with the evidence being stronger for women than for men.

Wave-actuated power take-off device for electricity generation

Since 2008, Resolute Marine Energy, Inc. (RME) has been engaged in the development of a rigidly moored shallow-water point absorber wave energy converter, the "3D-WEC". RME anticipated that the 3D-WEC configuration with a fully buoyant point absorber buoy coupled to three power take off (PTO) units by a tripod array of tethers would achieve higher power capture than a more conventional 1-D configuration with a single tether and PTO. The investigation conducted under this program and documented herein addressed the following principal research question regarding RME's power take off (PTO) concept for its 3D-WEC: Is RME's winch-driven generator PTO concept, previously implemented at sub-scale and tested at the Ohmsett wave tank facility, scalable in a cost-effective manner to significant power levels e.g., 10 to 100kW?

To implement and evaluate the use of a situated-learning experience to prepare second-year pharmacy students to conduct medication history interviews in preparation for introductory pharmacy practice experiences (IPPE) at ambulatory clinic sites. Second-year doctor of pharmacy (PharmD) students (n=200) used the Medication Mysteries Infinite Case Tool, a game-like educational tool in which groups of 3 students assumed the roles of pharmacist, patient, and observer and rolled a die and drew cards to determine the drugs, patient personality, medication problems, and other variables that guided a medication history taking session. After the laboratory session, faculty members assessed students' medication history-taking skills. One hundred sixteen (58%) and 78 (39%) of 200 students achieved excellence or competence, respectively, on the final assessment. Two weeks after the assessment, 53 of 200 (26.5%) students completed a survey instrument. The respondents indicated that their self-confidence in conducting medical history taking significantly improved following completion of the learning experience. Using the Medication Mysteries Infinite Case Tool increased students' confidence and skills in conducting medication history taking prior to their clinical IPPE experience.

To determine the functional outcomes of laser in situ keratomileusis (LASIK) and photorefractive keratectomy (PRK) in patients taking isotretinoin, which is contraindicated for these procedures. Multicentre, retrospective, interventional case series METHODS: All patients taking isotretinoin who underwent LASIK or PRK from January 2003 to September 2017 were included (group 1). Patients were compared with those undergoing LASIK or PRK who had taken isotretinoin previously but not in the previous 6 months (group 2). Patients were included consecutively. A total of 113 patients (219 eyes) were included. No significant intraoperative or postoperative complications were found. There were no significant differences between the groups in terms of visual acuity, postoperative spherical equivalent, efficacy index, predictability, or safety index. When only PRK patients were taken into account, the efficacy index (p: 0.017), postoperative sphere (p: 0.041), and postoperative astigmatism (pLASIK and PRK can be performed effectively and safely in selected patients taking isotretinoin. The absolute exclusion of certain systemic medications should be reconsidered. Copyright © 2018 Elsevier Inc. All rights reserved.

A large scale survey reveals that chromosomal copy-number alterations significantly affect gene modules involved in cancer initiation and progression

2011-05-01

Full Text Available Abstract Background Recent observations point towards the existence of a large number of neighborhoods composed of functionally-related gene modules that lie together in the genome. This local component in the distribution of the functionality across chromosomes is probably affecting the own chromosomal architecture by limiting the possibilities in which genes can be arranged and distributed across the genome. As a direct consequence of this fact it is therefore presumable that diseases such as cancer, harboring DNA copy number alterations (CNAs, will have a symptomatology strongly dependent on modules of functionally-related genes rather than on a unique "important" gene. Methods We carried out a systematic analysis of more than 140,000 observations of CNAs in cancers and searched by enrichments in gene functional modules associated to high frequencies of loss or gains. Results The analysis of CNAs in cancers clearly demonstrates the existence of a significant pattern of loss of gene modules functionally related to cancer initiation and progression along with the amplification of modules of genes related to unspecific defense against xenobiotics (probably chemotherapeutical agents. With the extension of this analysis to an Array-CGH dataset (glioblastomas from The Cancer Genome Atlas we demonstrate the validity of this approach to investigate the functional impact of CNAs. Conclusions The presented results indicate promising clinical and therapeutic implications. Our findings also directly point out to the necessity of adopting a function-centric, rather a gene-centric, view in the understanding of phenotypes or diseases harboring CNAs.

2011-10-01

Progressive visual agnosia was discovered in the 20th century following the discovery of classical non-progressive visual agnosia. In contrast to the classical type, which is caused by cerebral vascular disease or traumatic injury, progressive visual agnosia is a symptom of neurological degeneration. The condition of progressive visual loss, including visual agnosia, and posterior cerebral atrophy was named posterior cortical atrophy (PCA) by Benson et al. (1988). Progressive visual agnosia is also observed in semantic dementia (SD) and other degenerative diseases, but there is a difference in the subtype of visual agnosia associated with these diseases. Lissauer (1890) classified visual agnosia into apperceptive and associative types, and it in most cases, PCA is associated with the apperceptive type. However, SD patients exhibit symptoms of associative visual agnosia before changing to those of semantic memory disorder. Insights into progressive visual agnosia have helped us understand the visual system and discover how we "perceive" the outer world neuronally, with regard to consciousness. Although PCA is a type of atypical dementia, its diagnosis is important to enable patients to live better lives with appropriate functional support.

With a 5-year survival rate of <5%, pancreatic cancer is one of the most rapidly fatal malignancies. Current protocols for the treatment of pancreas cancer are not as effective as we desire. In this study, we show that a novel Mucin-1 (MUC1)-based vaccine in combination with a cyclooxygenase-2 inhibitor (celecoxib), and low-dose chemotherapy (gemcitabine) was effective in preventing the progression of preneoplastic intraepithelial lesions to invasive pancreatic ductal adenocarcinomas. The study was conducted in an appropriate triple transgenic model of spontaneous pancreatic cancer induced by the KRAS(G12D) mutation and that expresses human MUC1 as a self molecule. The combination treatment elicited robust antitumor cellular and humoral immune responses and was associated with increased apoptosis in the tumor. The mechanism for the increased immune response was attributed to the down-regulation of circulating prostaglandin E(2) and indoleamine 2, 3,-dioxygenase enzymatic activity, as well as decreased levels of T regulatory and myeloid suppressor cells within the tumor microenvironment. The preclinical data provide the rationale to design clinical trials with a combination of MUC1-based vaccine, celecoxib, and gemcitabine for the treatment of pancreatic cancer.

The clinical differentiation of Parkinson's disease (PD) from multiple system atrophy (MSA) and progressive supranuclear palsy (PSP) may be challenging, especially in their early stages. The aim of this study was to evaluate the utility of apparent diffusion coefficient (ADC) measurement to distinguish among these degenerative disorders. Twenty-five MSA, 20 PSP, and 17 PD patients and 18 healthy controls were retrospectively studied. Axial diffusion-weighted and T2-weighted images were obtained using a 3-T MR system. Regions of interest (ROIs) were precisely placed in the midbrain, pons, putamen, globus pallidus, caudate nucleus, thalamus, superior cerebellar peduncle, middle cerebellar peduncle, cerebellar white matter, and cerebellar dentate nucleus, and the regional ADC (rADC) value was calculated in each ROI. In MSA, rADC values in the pons, middle cerebellar peduncle, cerebellar white matter, and cerebellar dentate nucleus were significantly higher than in PSP, PD, and controls. Furthermore, rADC values in the posterior putamen were significantly higher in MSA than in PSP and controls. In PSP, rADC values were significantly higher in the globus pallidus and midbrain than in MSA, PD, and controls. Furthermore, rADC values in the caudate nucleus and superior cerebellar peduncle were significantly higher in PSP than in MSA and controls. In PD, there were no significant differences in the rADC values compared to in MSA, PSP, and controls in all regions. Evaluation of rADC values in characteristic lesions in MSA, PSP, and PD by placing ROIs using 3-T systems can provide useful additional information for differentiating these disorders. (orig.)

We investigated the psychological profiles and emotional regulation characteristics of women involved in risk-taking sports. The research sample (N=180) consisted of three groups of women engaged in: (1) non-risk sports (N=90); (2) risk-taking sports for leisure purposes (N=53); or (3) risk-taking sports as professionals (N=37). Each participant completed five questionnaires, the Sensation Seeking Scale, the Bem Sex Role Inventory, the Barratt Impulsiveness Scale, Risk & Excitement Inventory, and the Toronto Alexithymia Scale. The results revealed significant differences between the groups' profiles. Of particular interest are the differences that exist between the profiles of Group 2 (escape profile, masculine gender identity, and high scores on sensation seeking, impulsivity, alexithymia) and Group 3 (compensation profile, androgynous gender identity, average score on sensation seeking, and low scores on impulsivity, alexithymia). We propose that the professional woman might be considered a model for preventing destructive risk-taking behaviors.

Take-or-Pay under Japanese energy policy

International Nuclear Information System (INIS)

Namikawa, Ryoichi

2003-01-01

Japan has tried to increase the import of liquefied natural gas (LNG) because of the nation's fragile energy supply structure. In Japan, almost all LNG is imported under long-term contracts with a Take-or-Pay clause, although buyers assume considerable risk under such a clause. This paper tries to determine why the Take-or-Pay clause has been retained in LNG import contracts in Japan, focusing on the relation between Take-or-Pay and energy security policy. It is found that the government has not pursued a consistent, consecutive policy on Take-or-Pay under the changing energy situation after oil crises. On the one hand, the government has accepted Take-or-Pay because it secures a stable supply of LNG, but on the other hand, it has tried to scrap Take-or-Pay in order to reduce buyers' risk. Furthermore, it was not until the middle/late 1990s that the government implemented deregulation. It is concluded that the government's energy security policy has played an important role in keeping Take-or-Pay in Japan

2011-12-01

In recent years, significant progresses have been got in study on pathogenesis, treatment and prognosis of myelodysplastic syndromes (MDS), especially on use of new technology, that has great importance for cytogenetics of MDS. Recently, the progress of cytogenetic detection in MDS is very remarkable. Based on the metaphase cytogenetics (MC) method, prognostic significance of cytogenetics in MDS was clarified gradually. For example, people have known the prognostic significance of 12 p-, 11 q-, +21, t(11(q23)), although these genetic abnormalities are rare in the MDS. In addition, chromosome mutation emerged in the process of MDS may indicate the poor prognosis. On the other hand, with the use of SNP-A and aCGH in the study of genetics, MDS cytogenetic abnormality detection rate has been further improved and can reach to 78%. At the same time, some of MDS patients with the "normal karyotype" detected by MC have new hidden aberrations through the SNP or CGH detection, and these patients have a poorer prognosis. In this review, the advances of study on cytogenetic detection for MDS based on MC and SNP-A or aCGH methods are summarized.

Language Classroom Risk-Taking Behavior in a Performed Culture-Based Program

Stephen D. Luft

2013-01-01

Full Text Available While several studies have investigated the role of risk-taking in language learning, the findings of these studies may not be generalizable to language learning where the performed culture approach (PCA is used. This study describes the relationship between language learning and risk-taking in PCA, and the relationship between risk-taking and personal study habits, teaching style, daily grading, and classroom dynamics. Data were collected by means of a questionnaire. This study finds that risk-taking behavior has a moderate positive relationship with student performance in PCA. While questionnaire items related to teaching style and classroom dynamics are not found to significantly correlate with students’ risk-taking behavior, some items related to daily grading and personal study habits are found to have a moderate positive relationship with risk-taking behavior. Based on these findings, it is recommended that further research investigate the relationship between assessment and risktaking in language learning. As second language acquisition researchers have investigated the role of affective variables in language learning, risk-taking has frequently been identified as a variable linked with success (Beebe, 1983; Ely, 1986; Naiman, Frolich, Stern, & Todesco, 1978; Rubin, 1975; Samimy & Pardin, 1994; Samimy & Tabuse, 1992. However, it is difficult to apply these findings to language classrooms that use the performed culture approach (PCA, an approach to the teaching of East Asian languages, for two reasons: (a PCA’s focus on the learning of a foreign culture could mean that greater risk is involved in 106 Luft language learning than in a typical language classroom; (b PCA creates a language learning experience for which the risks involved are different than those in language classrooms where other approaches are used.

Full Text Available Introduction: In the general population, medication nonadherence contributes to poorer outcomes. However, little is known about medication adherence among adults with chronic kidney disease (CKD. We evaluated the association of self-reported medication adherence with CKD progression and all-cause death in patients with CKD. Methods: In this prospective observational study of 3305 adults with mild-to-moderate CKD enrolled in the Chronic Renal Insufficiency Cohort (CRIC Study, the baseline self-reported medication adherence was assessed by responses to 3 questions and categorized as high, medium, and low. CKD progression (50% decline in eGFR or incident end-stage renal disease and all-cause death were measured using multivariable Cox proportional hazards. Results: Of the patients, 68% were categorized as high adherence, 17% medium adherence, and 15% low adherence. Over a median follow-up of 6 years, there were 969 CKD progression events and 675 deaths. Compared with the high-adherence group, the low-adherence group experienced increased risk for CKD progression (hazard ratio = 1.27, 95% confidence interval = 1.05, 1.54 after adjustment for sociodemographic and clinical factors, cardiovascular medications, number of medication types, and depressive symptoms. A similar association existed between low adherence and all-cause death, but did not reach standard statistical significance (hazard ratio = 1.14 95% confidence interval = 0.88, 1.47. Conclusion: Baseline self-reported low medication adherence was associated with an increased risk for CKD progression. Future work is needed to better understand the mechanisms underlying this association and to develop interventions to improve adherence. Keywords: CKD, death, medication adherence, progression

The present study aimed to clarify the features and management of non-variceal upper gastrointestinal bleeding (UGIB) in Japanese patients taking antithrombotic agents. We retrospectively investigated the medical records of 560 patients who underwent emergency endoscopy for UGIB from 2002 to 2013. The patients were divided into two groups: group A, antithrombotic agent use; and group NA, no antithrombotic agent use. We compared clinical characteristics, comorbidities, and causes of UGIB between the groups. We also investigated management with antithrombotics. Of 560 patients with UGIB, 27.5% were taking antithrombotics, and this proportion gradually increased during the study period. Mean hemoglobin levels on admission were significantly lower in group A (8.0 ± 1.7 g/dL) than in group NA (8.9 ± 2.9 g/dL) (P bleeding was lower in group A than in group NA (P < 0.001), and the rate of endoscopic hemostasis was significantly higher in group A (98.7%) than in group NA (94.3%) (P = 0.022). After the release of the 2012 Japan Gastroenterological Endoscopy Society guidelines, the antithrombotic agent cessation periods were significantly shortened (P < 0.001). Among patients with UGIB, those taking antithrombotics exhibited more severe clinical signs. However spurting hemorrhage was rare. Antithrombotics may be resumed early after endoscopic hemostasis. © 2014 The Authors. Digestive Endoscopy © 2014 Japan Gastroenterological Endoscopy Society.

Pulmonary Hypertension Due to Left Ventricular Cardiomyopathy: Is it the Result or Cause of Disease Progression?

Science.gov (United States)

Adusumalli, Srinath; Mazurek, Jeremy A

2017-12-01

The purpose of this review is to define pulmonary hypertension in the setting of left heart disease (PH-LHD), discuss its epidemiology and pathophysiology, and highlight the cause and effect relationship it has with disease progression in the setting of cardiomyopathy. Both pulmonary hypertension (PH) and heart failure are becoming increasingly common. As such, PH-LHD is now the most common form of PH. The pathophysiology of the condition relates to backward transmission of elevated left ventricular filling pressures into the pulmonary circulation and, ultimately, right ventricular (RV) strain/dysfunction. It is evident that these pathophysiologic processes are both the effect and cause of left heart disease progression. In this review, we describe the complex relationship between disease progression in left ventricular cardiomyopathy and PH-LHD. Clinicians and researchers should take note of the importance of PH-LHD and RV dysfunction to appropriately risk stratify patients and develop therapies for the condition.

Learning progressions from a sociocultural perspective: response to "co-constructing cultural landscapes for disciplinary learning in and out of school: the next generation science standards and learning progressions in action"

Science.gov (United States)

Tytler, Russell

2016-10-01

This article discusses a case for a different, socio-cultural way of looking at learning progressions as treated in the next generation science standards (NGSS) as described by Ralph Cordova and Phyllis Balcerzak's paper "Co-constructing cultural landscapes for disciplinary learning in and out of school: the next generation science standards and learning progressions in action". The paper is interesting for a number of reasons, and in this response I will identify different aspects of the paper and link the points made to my own research, and that of colleagues, as complementary perspectives. First, the way that the science curriculum is conceived as an expanding experience that moves from the classroom into the community, across subjects, and across time, links to theoretical positions on disciplinary literacies and notions of learning as apprenticeship into the discursive tools, or `habits of mind' as the authors put it, that underpin disciplinary practice. Second, the formulation of progression through widening communities of practice is a strong feature of the paper, and shows how children take on the role of scientists through this expanding exposure. I will link this approach to some of our own work with school—community science partnerships, drawing on the construct of boundary crossing to tease out relations between school science and professional practice. Third, the demonstration of the expansion of the children's view of what scientists do is well documented in the paper, illustrated by Figure 13 for instance. However I will, in this response, try to draw out and respond to what the paper is saying about the nature of progression; what the progression consists of, over what temporal or spatial dimensions it progresses, and how it can productively frame curriculum processes.

Validating predictors of disease progression in a large cohort of primary-progressive multiple sclerosis based on a systematic literature review.

Directory of Open Access Journals (Sweden)

Full Text Available New agents with neuroprotective or neuroregenerative potential might be explored in primary-progressive Multiple Sclerosis (PPMS--the MS disease course with leading neurodegenerative pathology. Identification of patients with a high short-term risk for progression may minimize study duration and sample size. Cohort studies reported several variables as predictors of EDSS disability progression but findings were partially contradictory.To analyse the impact of published predictors on EDSS disease progression in a large cohort of PPMS patients.A systematic literature research was performed to identify predictors for disease progression in PPMS. Individual case data from the Sylvia Lawry Centre (SLC and the Hamburg MS patient database (HAPIMS was pooled for a retrospective validation of these predictors on the annualized EDSS change.The systematic literature analysis revealed heterogeneous data from 3 prospective and 5 retrospective natural history cohort studies. Age at onset, gender, type of first symptoms and early EDSS changes were available for validation. Our pooled cohort of 597 PPMS patients (54% female had a mean follow-up of 4.4 years and mean change of EDSS of 0.35 per year based on 2503 EDSS assessments. There was no significant association between the investigated variables and the EDSS-change.None of the analysed variables were predictive for the disease progression measured by the annualized EDSS change. Whether PPMS is still unpredictable or our results may be due to limitations of cohort assessments or selection of predictors cannot be answered. Large systematic prospective studies with new endpoints are needed.

Balke, Maryam; Lehmann, Helmar C; Fink, Gereon R; Wunderlich, Gilbert

2017-07-01

History  A 30-year-old man presented with a history of progressive muscle weakness, difficulty in concentrating, and a slender habitus since early childhood. Marfan syndrome was suspected since the age of 14. Examinations  13 years later he was examined by Marfan experts and by genetic testing and Marfan syndrome could not be confirmed. Further neurological examination revealed the suspected diagnosis of myotonic dystrophy type 1, which was confirmed by genetic testing. Treatment and course  Similar to Marfan syndrome, myotonic dystrophy is a multisystemic disorder with the risk of cardiac arrythmias. It is necessary to provide an interdisciplinary care by neurologists, internists, ophthalmologists, speech therapists, and physiotherapists. Conclusion  It is not enough to take the habitus as the principle sign to diagnose Marfan syndrome. Furthermore, it is essential to consider symptoms that are not typical for Marfan syndrome, such as cognitive deficiencies or progressive paresis. © Georg Thieme Verlag KG Stuttgart · New York.

Psychological functioning in two types of multiple sclerosis (MS) patients is assessed: primary progressive (PP) and secondary progressive (SP) patients. On the basis of differences in clinical course and underlying pathology we hypothesized that primary progressive patients and secondary...... progressive patients might have different psychological functioning. Seventy patients treated in an MS centre were examined cross-sectionally. Forty had an SP course of MS and 30 a PP course.

There is a large unmet need for treatments for patients with progressive multiple sclerosis (MS). Phase 2 studies with cerebrospinal fluid (CSF) biomarker outcomes may be well suited for the initial evaluation of efficacious treatments. To evaluate the effect of monthly oral methylprednisolone pulse treatment on intrathecal inflammation in progressive MS. In this open-label phase 2A study, 15 primary progressive and 15 secondary progressive MS patients received oral methylprednisolone pulse treatment for 60 weeks. Primary outcome was changes in CSF concentrations of osteopontin. Secondary outcomes were other CSF biomarkers of inflammation, axonal damage and demyelination; clinical scores; magnetic resonance imaging measures of disease activity, magnetization transfer ratio (MTR) and diffusion tensor imaging (DTI); motor evoked potentials; and bone density scans. We found no change in the CSF concentration of osteopontin, but we observed significant improvement in clinical scores, MTR, DTI and some secondary CSF outcome measures. Adverse events were well-known side effects to methylprednisolone. Monthly methylprednisolone pulse treatment was safe, but had no effect on the primary outcome. However, improvements in secondary clinical and MRI outcome measures suggest that this treatment regimen may have a beneficial effect in progressive MS. © The Author(s), 2015.

Purpose To determine the rate of progression and optimal follow up time in patients with advanced stage retinitis pigmentosa (RP) comparing the use of fundus autofluorescence imaging and spectral domain optical coherence tomography. Design Retrospective analysis of progression rate. Methods Longitudinal imaging follow up in 71 patients with retinitis pigmentosa was studied using the main outcome measurements of hyperautofluoresent ring horizontal diameter and vertical diameter along with ellipsoid zone line width from spectral domain optical coherence tomography. Test-retest reliability and the rate of progression were calculated. The interaction between the progression rates was tested for sex, age, mode of inheritance, and baseline measurement size. Symmetry of left and right eye progression rate was also tested. Results Significant progression was observed in >75% of patients during the 2 year mean follow up. The mean annual progression rates of ellipsoid zone line, and hyperautofluorescent ring horizontal diameter and vertical diameter were 0.45° (4.9%), 0.51° (4.1%), and 0.42° (4.0%), respectively. The e llipsoid zone line width, and hyperautofluorescent ring horizontal diameter and vertical diameter had low test-retest variabilities of 8.9%, 9.5% and 9.6%, respectively. This study is the first to demonstrate asymmetrical structural progression rate between right and left eye, which was found in 19% of patients. The rate of progression was significantly slower as the disease approached the fovea, supporting the theory that RP progresses in an exponential fashion. No significant interaction between progression rate and patient age, sex, or mode of inheritance was observed. Conclusions Fundus autofluorescence and optical coherence tomography detect progression in patients with RP reliably and with strong correlation. These parameters may be useful alongside functional assessments as the outcome measurements for future therapeutic trials. Follow-up at 1 year

Progression of Parkinson's disease (PD) is highly variable, indicating that differences between slow and rapid progression forms could provide valuable information for improved early detection and management. Unfortunately, this represents a complex problem due to the heterogeneous nature of humans in regards to demographic characteristics, genetics, diet, environmental exposures and health behaviors. In this pilot study, we employed high resolution mass spectrometry-based metabolic profiling to investigate the metabolic signatures of slow versus rapidly progressing PD present in human serum. Archival serum samples from PD patients obtained within 3 years of disease onset were analyzed via dual chromatography-high resolution mass spectrometry, with data extraction by xMSanalyzer and used to predict rapid or slow motor progression of these patients during follow-up. Statistical analyses, such as false discovery rate analysis and partial least squares discriminant analysis, yielded a list of statistically significant metabolic features and further investigation revealed potential biomarkers. In particular, N8-acetyl spermidine was found to be significantly elevated in the rapid progressors compared to both control subjects and slow progressors. Our exploratory data indicate that a fast motor progression disease phenotype can be distinguished early in disease using high resolution mass spectrometry-based metabolic profiling and that altered polyamine metabolism may be a predictive marker of rapidly progressing PD.

Extensive correlative studies in human prostate cancer as well as studies in vitro and in mouse models indicate that fibroblast growth factor receptor (FGFR) signaling plays an important role in prostate cancer progression. In this study, we used a probe compound for an FGFR inhibitor, which potently inhibits FGFR-1-3 and significantly inhibits FGFR-4. The purpose of this study is to determine whether targeting FGFR signaling from all four FGFRs will have in vitro activities consistent with inhibition of tumor progression and will inhibit tumor progression in vivo. Effects of AZ8010 on FGFR signaling and invasion were analyzed using immortalized normal prostate epithelial (PNT1a) cells and PNT1a overexpressing FGFR-1 or FGFR-4. The effect of AZ8010 on invasion and proliferation in vitro was also evaluated in prostate cancer cell lines. Finally, the impact of AZ8010 on tumor progression in vivo was evaluated using a VCaP xenograft model. AZ8010 completely inhibits FGFR-1 and significantly inhibits FGFR-4 signaling at 100 nmol/L, which is an achievable in vivo concentration. This results in marked inhibition of extracellular signal-regulated kinase (ERK) phosphorylation and invasion in PNT1a cells expressing FGFR-1 and FGFR-4 and all prostate cancer cell lines tested. Treatment in vivo completely inhibited VCaP tumor growth and significantly inhibited angiogenesis and proliferation and increased cell death in treated tumors. This was associated with marked inhibition of ERK phosphorylation in treated tumors. Targeting FGFR signaling is a promising new approach to treating aggressive prostate cancer.

The paper describes operating characteristics of a personal-computer (PC)-based Reasonable Further Progress (RFP) tracking system developed for use by EPA to evaluate the progress that nonattainment areas are making toward meeting a 15% volatile organic compound (VOC) reduction specified in the Clean Air Act Amendments (CAAA) of 1990. Details of the program's capabilities, file handling, reporting, and graphics are reported. In order to track the emission reductions resulting from these strategies, emissions reported in the RFP projection inventories will be compared with actual emissions reported in periodic adjusted-base inventories, that are also required by the CAAA. However, the comparison will take place a number of years in the future.

Progressive degradation of alloy 690 and the development of a significant improvement in alloy 800CR

Staehle, Roger W.; Arioka, Koji; Tapping, Robert

2015-01-01

The present most widely used alloys for tubing in steam generators and structural materials in water cooled reactors are Alloy 690 and Alloy 800. However, both alloys, while improved over Alloy 600 may not meet the needs of longer range applications in the range of 80-100 years. Alloy 690 sustains damage resulting from the formation of cavities at grain boundaries which eventually cover about 50% of the area of the grain boundaries with the remainder covering being covered with carbides. The cavities seem to nucleate on the carbides leaving the grain boundaries a structure of cavities and carbides. Such a structure will lead the Alloy 690 to fail completely. Normal Alloy 800 does not produce such cavities and probably retains a large amount of its corrosion resistance but does sustain progressive SCC at low rate. A new alloy, 800CR, has been developed in a collaboration among Arioka, Tapping, and Staehle. This alloy is based on a Cr composition of 23.5-27% with the remainder retaining the previous Alloy 800 composition. 800CR sustains a crack velocity about 100 times less than Alloy 690 and a negligible rate of initiation. The 800CR, alloy is now seeking a patent. (authors)

There are numerous examples of no-take marine reserves effectively conserving fish stocks within their boundaries. However, no-take reserves can be rendered ineffective and turned into 'paper parks' through poor compliance and weak enforcement of reserve regulations. Long-term monitoring is thus essential to assess the effectiveness of marine reserves in meeting conservation and management objectives. This study documents the present state of the 15-year old no-take zone (NTZ) of South El Ghargana within the Nabq Managed Resource Protected Area, South Sinai, Egyptian Red Sea. Previous studies credited willing compliance by the local fishing community for the increased abundances of targeted fish within the designated NTZ boundaries compared to adjacent fished or take-zones. We compared benthic habitat and fish abundance within the NTZ and the adjacent take sites open to fishing, but found no significant effect of the reserve. Instead, the strongest evidence was for a simple negative relationship between fishing pressure and distance from the closest fishing village. The abundance of targeted piscivorous fish increased significantly with increasing distance from the village, while herbivorous fish showed the opposite trend. This gradient was supported by a corresponding negative correlation between the amount of discarded fishing gear observed on the reef and increasing distance from the village. Discarded fishing gear within the NTZ suggested decreased compliance with the no-take regulations. Our findings indicate that due to non-compliance the no-take reserve is no longer functioning effectively, despite its apparent initial successes and instead a gradient of fishing pressure exists with distance from the nearest fishing community.

Functional significance of erythropoietin in renal cell carcinoma

Morais, Christudas; Johnson, David W; Vesey, David A; Gobe, Glenda C

2013-01-01

One of the molecules regulated by the transcription factor, hypoxia inducible factor (HIF), is the hypoxia-responsive hematopoietic factor, erythropoietin (EPO). This may have relevance to the development of renal cell carcinoma (RCC), where mutations of the von Hippel-Lindau (VHL) gene are major risk factors for the development of familial and sporadic RCC. VHL mutations up-regulate and stabilize HIF, which in turn activates many downstream molecules, including EPO, that are known to promote angiogenesis, drug resistance, proliferation and progression of solid tumours. HIFs typically respond to hypoxic cellular environment. While the hypoxic microenvironment plays a critical role in the development and progression of tumours in general, it is of special significance in the case of RCC because of the link between VHL, HIF and EPO. EPO and its receptor, EPOR, are expressed in many cancers, including RCC. This limits the use of recombinant human EPO (rhEPO) to treat anaemia in cancer patients, because the rhEPO may be stimulatory to the cancer. EPO may also stimulate epithelial-mesenchymal transition (EMT) in RCC, and pathological EMT has a key role in cancer progression. In this mini review, we summarize the current knowledge of the role of EPO in RCC. The available data, either for or against the use of EPO in RCC patients, are equivocal and insufficient to draw a definitive conclusion

In order to study the significance of CD(276) and CD(133) in the development and progression of colorectal cancer (CRC), the expression of CD(276) and CD(133) was detected by immunohistochemistry in CRC and precancerous lesions. The results showed that the intensity of CD(276) and CD(133) in CRC samples was higher than that in adenoma group and non-adenoma group. CD(276) and CD(133) single and double positive expression were significantly correlated with CRC lymph node metastasis, distant metastasis and survival. CD(276) and CD(133) are significantly correlated to the development and progression of CRC and associated with poor prognosis.

It has been proposed that antioxidants may prevent cellular damage in the retina by reacting with free radicals that are produced in the process of light absorption. Higher dietary levels of antioxidant vitamins and minerals may reduce the risk of progression of age-related macular degeneration (AMD). The objective of this review was to assess the effects of antioxidant vitamin or mineral supplementation on the progression of AMD in people with AMD. We searched CENTRAL (2017, Issue 2), MEDLINE Ovid (1946 to March 2017), Embase Ovid (1947 to March 2017), AMED (1985 to March 2017), OpenGrey (System for Information on Grey Literature in Europe, the ISRCTN registry (www.isrctn.com/editAdvancedSearch), ClinicalTrials.gov (www.clinicaltrials.gov) and the WHO International Clinical Trials Registry Platform (ICTRP) (www.who.int/ictrp/search/en). We did not use any date or language restrictions in the electronic searches for trials. We last searched the electronic databases on 29 March 2017. We included randomised controlled trials (RCTs) that compared antioxidant vitamin or mineral supplementation (alone or in combination) to placebo or no intervention, in people with AMD. Both review authors independently assessed risk of bias in the included studies and extracted data. One author entered data into RevMan 5; the other author checked the data entry. We graded the certainty of the evidence using GRADE. We included 19 studies conducted in USA, Europe, China, and Australia. We judged the trials that contributed data to the review to be at low or unclear risk of bias.Nine studies compared multivitamins with placebo (7 studies) or no treatment (2 studies) in people with early and moderate AMD. The duration of supplementation and follow-up ranged from nine months to six years; one trial followed up beyond two years. Most evidence came from the Age-Related Eye Disease Study (AREDS) in the USA. People taking antioxidant vitamins were less likely to progress to late AMD (odds ratio

longitudinal grey matter changes in the non-fluent/agrammatic variant of primary progressive aphasia. Graph theoretical analysis of the speech/language network showed that regions with shorter functional paths to the epicentre exhibited greater longitudinal atrophy. The network contained three modules, including a left inferior frontal gyrus/supplementary motor area, which was most strongly connected with the epicentre. The aslant tract was the white matter pathway connecting these two regions and showed the most significant correlation between fractional anisotropy and white matter longitudinal atrophy changes. This study showed that the pattern of longitudinal atrophy progression in the non-fluent/agrammatic variant of primary progressive aphasia relates to the strength of connectivity in pre-determined functional and structural large-scale speech production networks. These findings support the hypothesis that the spread of neurodegeneration occurs by following specific anatomical and functional neuronal network architectures. © The Author (2016).

Lipid-Altering Therapies and the Progression of Atherosclerotic Disease

International Nuclear Information System (INIS)

Wierzbicki, Anthony S.

2007-01-01

Lipids play a key role in the progression of atherosclerosis, and lipid-lowering therapies have been studied for 30 years in coronary disease. Measurement of the progression of atherosclerosis through carotid intima-media thickness, coronary mean lumen diameter, and, mostly recently, intravascular ultrasound is generally accepted. This article reviews the role of lipid-lowering therapies in changing the rate of atherosclerosis progression in the coronary and carotid circulations. Statins are the primary therapy used to reduce atherosclerosis and cardiovascular events, including strokes and transient ischemic attacks, and have benefits in reducing events in patients undergoing carotid endarterectomy. In contrast, data for other agents, including fibrates and nicotinic acid, in reducing the progression of atherosclerosis are less extensive and not as well known. There is increasing interest in optimizing the whole lipid profile, as this might deliver extra benefits over and above statin therapy alone. Initial proof of this concept has recently come from studies that measured the progression of atherosclerosis and showed that adding nicotinic acid to statin therapy and, more directly, infusion of high-density lipoprotein-like particles reduced progression and indeed might induce regression of the disease. It is likely that the management of significant carotid stenosis will become ever more drug focused and will be customized to the lipid profile of each patient with intervention reserved only for late-stage symptomatic disease

Osteoarthritis (OA) structural changes take place over decades in humans. MRI can provide precise and reliable information on the joint structure and changes over time. In this study, we investigated the reliability of quantitative MRI in assessing knee OA structural changes in the experimental anterior cruciate ligament (ACL) dog model of OA. OA was surgically induced by transection of the ACL of the right knee in five dogs. High resolution three dimensional MRI using a 1.5 T magnet was performed at baseline, 4, 8 and 26 weeks post surgery. Cartilage volume/thickness, cartilage defects, trochlear osteophyte formation and subchondral bone lesion (hypersignal) were assessed on MRI images. Animals were killed 26 weeks post surgery and macroscopic evaluation was performed. There was a progressive and significant increase over time in the loss of knee cartilage volume, the cartilage defect and subchondral bone hypersignal. The trochlear osteophyte size also progressed over time. The greatest cartilage loss at 26 weeks was found on the tibial plateaus and in the medial compartment. There was a highly significant correlation between total knee cartilage volume loss or defect and subchondral bone hypersignal, and also a good correlation between the macroscopic and the MRI findings. This study demonstrated that MRI is a useful technology to provide a non-invasive and reliable assessment of the joint structural changes during the development of OA in the ACL dog model. The combination of this OA model with MRI evaluation provides a promising tool for the evaluation of new disease-modifying osteoarthritis drugs (DMOADs).

2018-03-30

Our primary objective was to report the current neuroimaging classification systems of spatial patterns of progression in glioblastoma. In addition, we aimed to report the terminology used to describe 'progression' and to assess the compliance with the Response Assessment in Neuro-Oncology (RANO) Criteria. We conducted a systematic review to identify all neuroimaging studies of glioblastoma that have employed a categorical classification system of spatial progression patterns. Our review was registered with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) registry. From the included 157 results, we identified 129 studies that used labels of spatial progression patterns that were not based on radiation volumes (Group 1) and 50 studies that used labels that were based on radiation volumes (Group 2). In Group 1, we found 113 individual labels and the most frequent were: local/localised (58%), distant/distal (51%), diffuse (20%), multifocal (15%) and subependymal/subventricular zone (15%). We identified 13 different labels used to refer to 'progression', of which the most frequent were 'recurrence' (99%) and 'progression' (92%). We identified that 37% (n = 33/90) of the studies published following the release of the RANO classification were adherent compliant with the RANO criteria. Our review reports significant heterogeneity in the published systems used to classify glioblastoma spatial progression patterns. Standardization of terminology and classification systems used in studying progression would increase the efficiency of our research in our attempts to more successfully treat glioblastoma.

Full Text Available The acuity of reasoning on Raven’s Progressive Matrices is strongly influenced by strategic determinants. Building on metamemory studies that highlight the influence of study-time allocation on memory development, we investigated children’s allocation of study time while solving these matrices. A total of 170 children aged 6–12 years completed a computerized short-form version of the standard matrices featuring items selected to represent a broad range of difficulties. Beyond analyzing changes in mean latencies and performances with age, we used generalized additive mixed models to explore within-participant variability in response times as a function of both item complexity and overall individual efficiency. Results revealed that individual differences in performances were significantly associated with children’s adaptive modulation of response times. Mediation analysis further indicated that response-time modulation contributed to age-related changes in performance. Taking account of study-time allocation in reasoning tasks may open up new avenues for the study of reasoning development and the assessment of intellectual functioning.

Assessing progress in the development of safety culture

International Nuclear Information System (INIS)

Rotaru, Ioan; Ghita, Sorin

1999-01-01

The concept of safety culture was introduced by the International Nuclear Safety Advisory Group (INSAG) in the Summary Report on the Post-Accident Meeting on the Chernobyl Accident in 1986. The concept was further expanded in the 1988 INSAG-3 report, Basic Safety Principles for Nuclear Power Plants, and again in 1991 in the INSAG-4 report. Recognizing the increasing role that safety culture is expected to play in nuclear installations worldwide, the Convention on Nuclear Safety states the Contracting Parties' desire 'to promote an effective nuclear safety culture'. The concept of safety culture is defined in INSAG-4 as follows: Safety culture is that assembly of characteristics and attitudes in organizations and individuals which establishes that, as an overriding priority, nuclear plant safety issues receive the attention warranted by their significance. Safety culture is also an amalgamation of values, standards, morals and norms of acceptable behaviour. These are aimed at maintaining a self disciplined approach to the enhancement of safety beyond legislative and regulatory requirements. Therefore, the safety culture has to be inherent in the thoughts and actions of all the individuals at every level in an organization. The leadership provided by top management is crucial. Safety culture applies to conventional and personal safety as well as nuclear safety. All safety consideration are affected by common points of beliefs, attitudes, behaviour, and cultural differences, closely linked to a shared system of values and standards. The paper poses questions and tries to find answers relative to issues like: - how to assess progress; - specific organizational indicators of a progressive safety culture; - detection of incipient weaknesses in safety culture (organizational issues, employee issues, technology issues); - revitalizing a weakened safety culture; - overall assesment of safety culture; - general evaluation model. In conclusion, there is no consistent and

Full Text Available Aging is a prominent topic in global health. The purpose of this report is to document progress in two of our research projects in Japan, which currently is the most aged society in the world. The Japan Gerontological Evaluation Study (JAGES is one of the largest nation-wide research projects on aging, with more than 100 000 participants in 2010 and 2013. One of the notable findings is that community participation is a significant determinant of older people’s health. We have also made progress in the development of the JAGES Health Equity Assessment and Response Tools (HEART, which is a management tool for developing age-friendly cities. This progress suggests that community perspective and management of health promotion in the communities are valuable and require further research.

Prehypertension is likely to progress to hypertension. The rate of progression is determined mostly by age and resting blood pressure but may also be attenuated by increased fitness. A graded exercise test was performed in 2303 men with prehypertension at the Veterans Affairs Medical Centers in Washington, DC. Four fitness categories were defined, based on peak metabolic equivalents (METs) achieved. We assessed the association between exercise capacity and rate of progression to hypertension (HTN). The median follow-up period was 7.8 years (mean (± SD) 9.2±6.1 years). The incidence rate of progression from prehypertension to hypertension was 34.4 per 1000 person-years. Exercise capacity was a strong and independent predictor of the rate of progression. Compared to the High-Fit individuals (>10.0 METs), the adjusted risk for developing HTN was 66% higher (hazard ratio, 1.66; 95% CI, 1.2 to 2.2; P=0.001) for the Low-Fit and, similarly, 72% higher (hazard ratio, 1.72; 95% CI, 1.2 to 2.3; P=0.001) for the Least-Fit individuals, whereas it was only 36% for the Moderate-Fit (hazard ratio, 1.36; 95% CI, 0.99 to 1.80; P=0.056). Significant predictors for the progression to HTN were also age (19% per 10 years), resting systolic blood pressure (16% per 10 mm Hg), body mass index (15.3% per 5 U), and type 2 diabetes mellitus (2-fold). In conclusion, an inverse, S-shaped association was shown between exercise capacity and the rate of progression from prehypertension to hypertension in middle-aged and older male veterans. The protective effects of fitness were evident when exercise capacity exceeded 8.5 METs. These findings emphasize the importance of fitness in the prevention of hypertension.

2016-09-01

This paper examines decision-making around sexual behavior among reservation-based American Indian youth. Focus group discussions were conducted with youth ages 13-19 years old. Through these discussions, we explored youth's knowledge, attitudes and behaviors related to sexual risk taking through the lens of the protection motivation theory to inform the adaptation of an evidence-based HIV prevention intervention. Findings suggest that condom use self-efficacy and HIV prevention knowledge is low, vulnerability to sexually transmitted infections is lacking and alcohol plays a significant role in sexual risk taking in this population. In addition, parental monitoring and peer influence may contribute to or protect against sexual risk taking. Results suggest that future HIV prevention interventions should be delivered to gender-specific peer groups, include a parental component, teach sexual health education and communication skills, integrate substance-use prevention, and work to remove stigma around obtaining and using condoms.

Tumor-associated macrophages (TAMs) promote tumor progression and have an effect on survival in human cancer. However, little is known regarding their influence on tumor progression and prognosis in human hilar cholangiocarcinoma. We analyzed surgically resected tumor specimens of hilar cholangiocarcinoma (n = 47) for distribution and localization of TAMs, as defined by expression of CD68. Abundance of TAMs was correlated with clinicopathologic characteristics, tumor recurrence and patients’ survival. Statistical analysis was performed using SPSS software. Patients with high density of TAMs in tumor invasive front (TIF) showed significantly higher local and overall tumor recurrence (both ρ < 0.05). Furthermore, high density of TAMs was associated with decreased overall (one-year 83.6 % vs. 75.1 %; three-year 61.3 % vs. 42.4 %; both ρ < 0.05) and recurrence-free survival (one-year 93.9 % vs. 57.4 %; three-year 59.8 % vs. 26.2 %; both ρ < 0.05). TAMs in TIF and tumor recurrence, were confirmed as the only independent prognostic variables in the multivariate survival analysis (all ρ < 0.05). Overall survival and recurrence free survival of patients with hilar cholangiocarcinoma significantly improved in patients with low levels of TAMs in the area of TIF, when compared to those with a high density of TAMs. These observations suggest their utilization as valuable prognostic markers in routine histopathologic evaluation, and might indicate future therapeutic approaches by targeting TAMs

Second harmonic generation reveals matrix alterations during breast tumor progression

Burke, Kathleen; Tang, Ping; Brown, Edward

2013-03-01

Alteration of the extracellular matrix in tumor stroma influences efficiency of cell locomotion away from the primary tumor into surrounding tissues and vasculature, thereby affecting metastatic potential. We study matrix changes in breast cancer through the use of second harmonic generation (SHG) of collagen in order to improve the current understanding of breast tumor stromal development. Specifically, we utilize a quantitative analysis of the ratio of forward to backward propagating SHG signal (F/B ratio) to monitor collagen throughout ductal and lobular carcinoma development. After detection of a significant decrease in the F/B ratio of invasive but not in situ ductal carcinoma compared with healthy tissue, the collagen F/B ratio is investigated to determine the evolution of fibrillar collagen changes throughout tumor progression. Results are compared with the progression of lobular carcinoma, whose F/B signature also underwent significant evolution during progression, albeit in a different manner, which offers insight into varying methods of tissue penetration and collagen manipulation between the carcinomas. This research provides insights into trends of stromal reorganization throughout breast tumor development.

To characterize the clinical features of patients with neurofibromatosis type 2 (NF2) and determine prognostic risk factors for progressive disabilities. In this retrospective cohort study of the Japanese national NF2 registry between 2009 and 2013, clinical data (demographic, history, oncologic, and neurologic) of 807 patients with a diagnosis of NF2 were analyzed. The overall severity of neurologic disability was assessed using a comprehensive 25-point scoring system encompassing a wide variety of neurologic deficits. In 587 patients in whom longitudinal disability data were available, multivariate logistic regression was performed to identify risk factors for significant progression of disability. The clinical characteristics of the Japanese NF2 population were heterogeneous. The median age of onset was 24 years (range, 1-80 years), the male:female ratio was 1:1.29, and the initial severity score was 4 (range, 0-22) out of 25 points. A family history of NF2 was present in 33% of the patients. Most frequent clinical features were bilateral cranial nerve VIII nerve sheath tumor (NST) in 87%, spinal NST in 80%, hearing loss in 65%, spinal dysfunction in 50%, intracranial meningioma in 49%, and facial paresis in 36%. The disability score progressed by ≥5 points in 6.1% of patients over the study period. Based on multivariate logistic regression analyses, the significant independent risk factors of progression (P value) included age of onset history (P = 0.007), positive treatment history (P = 0.026), hearing loss (P = 0.014), facial paresis (P = 0.015), blindness (P = 0.011), and hemiparesis (P = 0.025). The Japanese NF2 population has heterogeneous clinical features. Risk factors for progressive disability include younger age of onset, positive family history, positive treatment history, and specific neurologic deficits. Copyright © 2017 The Authors.

Effects of large scale development need to be monitored during different stages, the changes during construction, changes upon completion and changes over a period of several years and decades to evaluate the performance and functions. Effects on the ecosystem over a whole range of social, economic, ecological and geological systems will certainly give a holistic picture. These details, many a times, helps in disaster prevention and management programs. An ounce of prevention is worth a pound of cure. Total environmental approach should be physical as well as social environment as we cannot neglect the stake holders of the environmental segments and their needs. Social responsibility is to provide the minimum for the stake holders and then think of the development activities. It is necessary to take the society along with our plan for progress and also to prevent confrontations. (author)

The purpose of this study was to compare hematoma formation after breast core needle biopsy performed on patients undergoing and those not undergoing concurrent antithrombotic therapy. A prospective assessment of core needle biopsies (stereotactic, ultrasound guided, or MRI guided) performed on patients enrolled between September 2011 and July 2012 formed the basis of this study. Postprocedure mediolateral and craniocaudal mammograms were evaluated for the presence and size of hematomas. Patients were clinically evaluated for complications 24-48 hours after the procedure through telephone call or face-to-face consultation. Needle size, type of biopsy, and presence of hematoma and documented complications were correlated with use of antithrombotic agents (including aspirin, warfarin, clopidogrel, and daily nonsteroidal antiinflammatory medications). No clinically significant hematomas or bleeding complications were found. Eighty-nine of 617 (14.4%) non-clinically significant hematomas were detected on postprocedure mammograms. The probability of development of a non-clinically significant hematoma was 21.6% for patients taking antithrombotics and 13.0% for those not taking antithrombotics. Concurrent antithrombotic therapy and larger needle gauge were significant factors contributing to the probability of hematoma formation. The volume of the hematoma was not related to needle gauge or presence of antithrombotic therapy. No clinically significant hematomas were found. Because there are potential life-threatening risks to stopping antithrombotic therapy before breast biopsy, withholding antithrombotic therapy for core needle breast biopsy is not recommended because the incidence of non-clinically significant hematoma is low.

Knowledge of the natural course of acute pancreatitis (AP) and risk of progression to chronic pancreatitis (CP) is limited. The aims were to describe: (1) the incidence of progression from AP to CP, (2) prognostic factors for progression, and (3) the natural course and mortality of progressive AP. During 1977 to 1982, patients admitted to hospitals in Copenhagen with a diagnosis of AP or CP were included in a prospective cohort and followed up by the Danish registries in 2008. The subcohort analyses comprised 352 AP patients. Progressive AP was found in 85 patients (24.1%) during follow-up; 48.2% developed from alcoholic AP, 47.0% from idiopathic AP, and 4.8% from other causes. The mortality rate for patients with progressive AP was 2.7 times higher than in patients with nonprogressive acute pancreatitis, and 5.3 to 6.5 times higher than in the background population. In Cox regression analyses corrected for age, only smoking was of significance for the progression from AP to CP. Acute pancreatitis can progress to CP, not only from alcoholic but also from nonalcoholic AP. Smoking was the strongest risk factor associated with progression. The mortality rate for these patients was 5 to 6 times the mortality rate in the population.

It remains unclear whether changes in arterial wall inflammation are associated with subsequent changes in the rate of structural progression of atherosclerosis. In this sub-study of the dal-PLAQUE clinical trial, multi-modal imaging was performed using 18-fludeoxyglucose (FDG) positron emission tomography (PET, at 0 and 6 months) and magnetic resonance imaging (MRI, at 0 and 24 months). The primary objective was to determine whether increasing FDG uptake at 6 months predicted atherosclerosis progression on MRI at 2 years. Arterial inflammation was measured by the carotid FDG target-to-background ratio (TBR), and atherosclerotic plaque progression was defined as the percentage change in carotid mean wall area (MWA) and mean wall thickness (MWT) on MRI between baseline and 24 months. A total of 42 participants were included in this sub-study. The mean age of the population was 62.5 years, and 12 (28.6 %) were women. In participants with (vs. without) any increase in arterial inflammation over 6 months, the long-term changes in both MWT (% change MWT: 17.49 % vs. 1.74 %, p = 0.038) and MWA (% change MWA: 25.50 % vs. 3.59 %, p = 0.027) were significantly greater. Results remained significant after adjusting for clinical and biochemical covariates. Individuals with no increase in arterial inflammation over 6 months had no significant structural progression of atherosclerosis over 24 months as measured by MWT (p = 0.616) or MWA (p = 0.373). Short-term changes in arterial inflammation are associated with long-term structural atherosclerosis progression. These data support the concept that therapies that reduce arterial inflammation may attenuate or halt progression of atherosclerosis. (orig.)

A total of 42 participants were included in this sub-study. The mean age of the population was 62.5 years, and 12 (28.6 %) were women. In participants with (vs. without) any increase in arterial inflammation over 6 months, the long-term changes in both MWT (% change MWT: 17.49 % vs. 1.74 %, p = 0.038) and MWA (% change MWA: 25.50 % vs. 3.59 %, p = 0.027) were significantly greater. Results remained significant after adjusting for clinical and biochemical covariates. Individuals with no increase in arterial inflammation over 6 months had no significant structural progression of atherosclerosis over 24 months as measured by MWT (p = 0.616) or MWA (p = 0.373). Short-term changes in arterial inflammation are associated with long-term structural atherosclerosis progression. These data support the concept that therapies that reduce arterial inflammation may attenuate or halt progression of atherosclerosis. (orig.)

Tracking Progress in Carbon Capture and Storage

At the second Clean Energy Ministerial in Abu Dhabi, April 2011 (CEM 2), the Carbon Capture, Use and Storage Action Group (CCUS AG) presented seven substantive recommendations to Energy Ministers on concrete, near-term actions to accelerate global carbon capture and storage (CCS) deployment. Twelve CCUS AG governments agreed to advance progress against the 2011 recommendations by the third Clean Energy Ministerial (London, 25-26 April 2012) (CEM 3). Following CEM 2, the CCUS AG requested the IEA and the Global CCS Institute to report on progress made against the 2011 recommendations at CEM 3. Tracking Progress in Carbon Capture and Storage: International Energy Agency/Global CCS Institute report to the third Clean Energy Ministerial responds to that request. The report considers a number of key questions. Taken as a whole, what advancements have committed CCUS AG governments made against the 2011 recommendations since CEM 2? How can Energy Ministers continue to drive progress to enable CCS to fully contribute to climate change mitigation? While urgent further action is required in all areas, are there particular areas that are currently receiving less policy attention than others, where efforts could be redoubled? The report concludes that, despite developments in some areas, significant further work is required. CCS financing and industrial applications continue to represent a particularly serious challenge.

Assessing allowable take of migratory birds

Legal removal of migratory birds from the wild occurs for several reasons, including subsistence, sport harvest, damage control, and the pet trade. We argue that harvest theory provides the basis for assessing the impact of authorized take, advance a simplified rendering of harvest theory known as potential biological removal as a useful starting point for assessing take, and demonstrate this approach with a case study of depredation control of black vultures (Coragyps atratus) in Virginia, USA. Based on data from the North American Breeding Bird Survey and other sources, we estimated that the black vulture population in Virginia was 91,190 (95% credible interval = 44,520?212,100) in 2006. Using a simple population model and available estimates of life-history parameters, we estimated the intrinsic rate of growth (rmax) to be in the range 7?14%, with 10.6% a plausible point estimate. For a take program to seek an equilibrium population size on the conservative side of the yield curve, the rate of take needs to be less than that which achieves a maximum sustained yield (0.5 x rmax). Based on the point estimate for rmax and using the lower 60% credible interval for population size to account for uncertainty, these conditions would be met if the take of black vultures in Virginia in 2006 was < 3,533 birds. Based on regular monitoring data, allowable harvest should be adjusted annually to reflect changes in population size. To initiate discussion about how this assessment framework could be related to the laws and regulations that govern authorization of such take, we suggest that the Migratory Bird Treaty Act requires only that take of native migratory birds be sustainable in the long-term, that is, sustained harvest rate should be < rmax. Further, the ratio of desired harvest rate to 0.5 x rmax may be a useful metric for ascertaining the applicability of specific requirements of the National Environmental Protection Act.

The Glass Ceiling: Progress and Persistent Challenges

It has been written that since 2001, there has not been any significant progress and the glass ceiling is still intact. Women are still underrepresented in top positions (Anonymous, 2004). If this is true, the glass ceiling presents a major barrier between women and their desire to advance into executive or senior management positions. In addition…

Changing beliefs and behavior through experience-taking.

Kaufman, Geoff F; Libby, Lisa K

2012-07-01

The present research introduces the concept of experience-taking-the imaginative process of spontaneously assuming the identity of a character in a narrative and simulating that character's thoughts, emotions, behaviors, goals, and traits as if they were one's own. Six studies investigated the degree to which particular psychological states and features of narratives cause individuals, without instruction, to engage in experience-taking and investigated how the merger between self and other that occurs during experience-taking produces changes in self-judgments, attitudes, and behavior that align with the character's. Results from Studies 1-3 showed that being in a reduced state of self-concept accessibility while reading a brief fictional work increased-and being in a heightened state of self-concept accessibility decreased-participants' levels of experience-taking and subsequent incorporation of a character's personality trait into their self-concepts. Study 4 revealed that a first-person narrative depicting an ingroup character elicited the highest levels of experience-taking and produced the greatest change in participants' behavior, compared with versions of the narrative written in 3rd-person voice and/or depicting an outgroup protagonist. The final 2 studies demonstrated that whereas revealing a character's outgroup membership as a homosexual or African American early in a narrative inhibited experience-taking, delaying the revelation of the character's outgroup identity until later in the story produced higher levels of experience-taking, lower levels of stereotype application in participants' evaluation of the character, and more favorable attitudes toward the character's group. The implications of these findings in relation to perspective-taking, self-other overlap, and prime-to-behavior effects are discussed. PsycINFO Database Record (c) 2012 APA, all rights reserved

A pilot randomised controlled trial was conducted with postpartum mothers to assess the feasibility and impact of note-taking during newborn teaching. Controls received standard teaching; the intervention group received pen and paper to take notes. Subjects were called 2 days post-discharge to assess infant sleep position, breastfeeding, car seat use, satisfaction and information recall. 126 mothers were randomised. There was a consistent trend that intervention subjects were more likely to report infant supine sleep position (88% vs 78%, relative risks (RR) 1.13; 95% CI 0.95 to 1.34), breastfeeding (96% vs 86%, RR 1.11; 95% CI 0.99 to 1.25) and correct car seat use (98% vs 87%, RR 1.12; 95% CI 1.00 to 1.25). Satisfaction and information recall did not differ. Among first-time mothers, intervention subjects were significantly more likely to report infant supine sleep position (95% vs 65%, RR 1.46; 95% CI 1.06 to 2.00). Maternal note-taking is feasible and potentially efficacious in promoting desirable infant care.

A Duration Prediction Using a Material-Based Progress Management Methodology for Construction Operation Plans

Directory of Open Access Journals (Sweden)

Yongho Ko

2017-04-01

Full Text Available Precise and accurate prediction models for duration and cost enable contractors to improve their decision making for effective resource management in terms of sustainability in construction. Previous studies have been limited to cost-based estimations, but this study focuses on a material-based progress management method. Cost-based estimations typically used in construction, such as the earned value method, rely on comparing the planned budget with the actual cost. However, accurately planning budgets requires analysis of many factors, such as the financial status of the sectors involved. Furthermore, there is a higher possibility of changes in the budget than in the total amount of material used during construction, which is deduced from the quantity take-off from drawings and specifications. Accordingly, this study proposes a material-based progress management methodology, which was developed using different predictive analysis models (regression, neural network, and auto-regressive moving average as well as datasets on material and labor, which can be extracted from daily work reports from contractors. A case study on actual datasets was conducted, and the results show that the proposed methodology can be efficiently used for progress management in construction.

Experience sharing, emotional reciprocity, and turn-taking

Directory of Open Access Journals (Sweden)

Melisa eStevanovic

2015-04-01

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

Distance from a fishing community explains fish abundance in a no-take zone with weak compliance.

Directory of Open Access Journals (Sweden)

Sahir Advani

Full Text Available There are numerous examples of no-take marine reserves effectively conserving fish stocks within their boundaries. However, no-take reserves can be rendered ineffective and turned into 'paper parks' through poor compliance and weak enforcement of reserve regulations. Long-term monitoring is thus essential to assess the effectiveness of marine reserves in meeting conservation and management objectives. This study documents the present state of the 15-year old no-take zone (NTZ of South El Ghargana within the Nabq Managed Resource Protected Area, South Sinai, Egyptian Red Sea. Previous studies credited willing compliance by the local fishing community for the increased abundances of targeted fish within the designated NTZ boundaries compared to adjacent fished or take-zones. We compared benthic habitat and fish abundance within the NTZ and the adjacent take sites open to fishing, but found no significant effect of the reserve. Instead, the strongest evidence was for a simple negative relationship between fishing pressure and distance from the closest fishing village. The abundance of targeted piscivorous fish increased significantly with increasing distance from the village, while herbivorous fish showed the opposite trend. This gradient was supported by a corresponding negative correlation between the amount of discarded fishing gear observed on the reef and increasing distance from the village. Discarded fishing gear within the NTZ suggested decreased compliance with the no-take regulations. Our findings indicate that due to non-compliance the no-take reserve is no longer functioning effectively, despite its apparent initial successes and instead a gradient of fishing pressure exists with distance from the nearest fishing community.

Risk taking in adversarial situations: Civilization differences in chess experts.

Chassy, Philippe; Gobet, Fernand

2015-08-01

The projections of experts in politics predict that a new world order will emerge within two decades. Being multipolar, this world will inevitably lead to frictions where civilizations and states will have to decide whether to risk conflict. Very often these decisions are informed if not taken by experts. To estimate risk-taking across civilizations, we examined strategies used in 667,599 chess games played over eleven years by chess experts from 11 different civilizations. We show that some civilizations are more inclined to settle for peace. Similarly, we show that once engaged in the battle, the level of risk taking varies significantly across civilizations, the boldest civilization using the riskiest strategy about 35% more than the most conservative civilization. We discuss which psychological factors might underpin these civilizational differences. Copyright © 2015. Published by Elsevier B.V.

Serum metabolomics of slow vs. rapid motor progression Parkinson's disease: a pilot study.

Directory of Open Access Journals (Sweden)

James R Roede

Full Text Available Progression of Parkinson's disease (PD is highly variable, indicating that differences between slow and rapid progression forms could provide valuable information for improved early detection and management. Unfortunately, this represents a complex problem due to the heterogeneous nature of humans in regards to demographic characteristics, genetics, diet, environmental exposures and health behaviors. In this pilot study, we employed high resolution mass spectrometry-based metabolic profiling to investigate the metabolic signatures of slow versus rapidly progressing PD present in human serum. Archival serum samples from PD patients obtained within 3 years of disease onset were analyzed via dual chromatography-high resolution mass spectrometry, with data extraction by xMSanalyzer and used to predict rapid or slow motor progression of these patients during follow-up. Statistical analyses, such as false discovery rate analysis and partial least squares discriminant analysis, yielded a list of statistically significant metabolic features and further investigation revealed potential biomarkers. In particular, N8-acetyl spermidine was found to be significantly elevated in the rapid progressors compared to both control subjects and slow progressors. Our exploratory data indicate that a fast motor progression disease phenotype can be distinguished early in disease using high resolution mass spectrometry-based metabolic profiling and that altered polyamine metabolism may be a predictive marker of rapidly progressing PD.

To investigate the longitudinal spinal cord and brain changes in neuromyelitis optica (NMO) and multiple sclerosis (MS) and their associations with disability progression. We recruited 28 NMO, 22 MS, and 20 healthy controls (HC), who underwent both spinal cord and brain MRI at baseline. Twenty-five NMO and 20 MS completed 1-year follow-up. Baseline spinal cord and brain lesion loads, mean upper cervical cord area (MUCCA), brain, and thalamus volume and their changes during a 1-year follow-up were measured and compared between groups. All the measurements were also compared between progressive and non-progressive groups in NMO and MS. MUCCA decreased significantly during the 1-year follow-up in NMO not in MS. Percentage brain volume changes (PBVC) and thalamus volume changes in MS were significantly higher than NMO. MUCCA changes were significantly different between progressive and non-progressive groups in NMO, while baseline brain lesion volume and PBVC were associated with disability progression in MS. MUCCA changes during 1-year follow-up showed association with clinical disability in NMO. Spinal cord atrophy changes were associated with disability progression in NMO, while baseline brain lesion load and whole brain atrophy changes were related to disability progression in MS. • Spinal cord atrophy progression was observed in NMO. • Spinal cord atrophy changes were associated with disability progression in NMO. • Brain lesion and atrophy were related to disability progression in MS.

Highlights: • Significant progress on the development of welding procedures for European TBM achieved. • Fabrication processes feasibility based on diffusion and fusion welding demonstrated. • An optimized welding scenario/sequence for TBM box assembly identified. • Future qualification of pF/WPS proposed through realization of a number of QMUs. - Abstract: The paper reviews progress achieved in development of fabrication technologies and procedures applied for manufacturing of the TBM sub-components, like, HCLL and HCPB cooling plates, HCLL/HCPB stiffening plates, and HCLL/HCPB first wall and side caps. The used technologies are based on fusion and diffusion welding techniques taking into account specificities of the EUROFER97 steel. Development of a standardized procedure complying with professional codes and standards (RCC-MRx), a preliminary fabrication/welding procedure specification (pF/WPS), is described based on fabrication and non-destructive and destructive characterization of feasibility mock-ups (FMU) aimed at assessing the suitability of a fabrication process for fulfilling the design and fabrication specifications. The main FMUs characterization results are reported (e.g. pressure resistance and helium leak tightness tests, mechanical properties and microstructure at the weld joints, geometrical characteristics of the sub-components and internal cooling channels) and the key pF/WPS steps and parameters are outlined. Also, fabrication procedures for the TBM box assembly are presently under development for the establishment of an optimized assembly sequence/scenario and development of standardized welding procedure specifications. In conclusions, further steps towards the pF/WPS qualification are briefly discussed.

Frank and Fearless: Supporting Academic Career Progression for Women in an Australian Program

Directory of Open Access Journals (Sweden)

Polly Parker

2018-02-01

Full Text Available The underrepresentation of women in senior positions continues to be a major challenge in higher education and most other industries. In Australia, the career trajectory for academic women stalls at a lower level than that of their male counterparts. Concern about this situation in one Australian university led to the design and delivery of a career progression program to support women’s advancement from senior lecturer to associate professor. This study details the main features of the program, designed to facilitate women’s transition from being leading academics to academic leaders through a focus on leadership and career progression. We report the participants’ perceptions of its value based on survey data. We conclude that leadership development is difficult work and requires a supportive environment where risk-taking is encouraged, where frank and fearless feedback is provided, and where the individual is required to examine assumptions and biases and to assume a leadership identity.

From scientific progress to economic growth the economics and the economy of science

CERN Document Server

Witte, Frank

2017-01-01

he past few centuries have seen an enormous increase in living standards in many parts of the world and these economies have become more complex than ever before. At the same time, progress in science and technology has reached unprecedented heights, taking us far beyond the wildest dreams of a few generations ago. Questions as to how science, technology and the economy interact are pertinent and important ones, whose partial answers require a view "from across the fence" between disciplines. This book provides an introduction to the vast and varied field of the economics of science. It is a unique blend of an economic perspective on the way science works, what makes scientists tick, and a study of the impact of scientific and technological progress on economies and their growth. Whether it is about the speculative market of ideas or science and technology as engines of the economy, there is something here for economists, engineers and scientists alike.

Early-onset Conduct Problems: Predictions from daring temperament and risk taking behavior.

Science.gov (United States)

Bai, Sunhye; Lee, Steve S

2017-12-01

Given its considerable public health significance, identifying predictors of early expressions of conduct problems is a priority. We examined the predictive validity of daring, a key dimension of temperament, and the Balloon Analog Risk Task (BART), a laboratory-based measure of risk taking behavior, with respect to two-year change in parent, teacher-, and youth self-reported oppositional defiant disorder (ODD), conduct disorder (CD), and antisocial behavior. At baseline, 150 ethnically diverse 6- to 10-year old (M=7.8, SD=1.1; 69.3% male) youth with ( n =82) and without ( n =68) DSM-IV ADHD completed the BART whereas parents rated youth temperament (i.e., daring); parents and teachers also independently rated youth ODD and CD symptoms. Approximately 2 years later, multi-informant ratings of youth ODD, CD, and antisocial behavior were gathered from rating scales and interviews. Whereas risk taking on the BART was unrelated to conduct problems, individual differences in daring prospectively predicted multi-informant rated conduct problems, independent of baseline risk taking, conduct problems, and ADHD diagnostic status. Early differences in the propensity to show positive socio-emotional responses to risky or novel experiences uniquely predicted escalating conduct problems in childhood, even with control of other potent clinical correlates. We consider the role of temperament in the origins and development of significant conduct problems from childhood to adolescence, including possible explanatory mechanisms underlying these predictions.

Tackling the take-or-pay problem

Centrica, the gas sales, trading and services company previously part of British Gas plc, has renegotiated a number of its take-or-pay contracts with North Sea gas producers since the end of 1996. The contracts - a legacy of the British Gas monopoly era - had placed an increasing financial burden on the company as it was effectively forced to pay above-market prices for gas which it did not always want to take, while trying to remain competitive in a market where an ever growing number of independent gas suppliers were offering low-cost supplies. The author looks at how Centrica has tackled its take-or-pay problem. (author)

The Fusion Program at General Atomic Company, supported by the U.S. Department of Energy, has made significant progress in all areas of investigation during the past year and several new projects have been initiated. A program has been initiated to provide neutral beam auxiliary plasma heating systems on Doublet III; the first phase of neutral injection experiments would begin in February 1980. The Doublet IIA program has been redirected toward an examination of the possibility of using radio frequency energy as an auxiliary plasma heating method. The TNS program examined several candidate TNS devices, basically a noncircular tokamak, which would operate in an ignited, deuterium-tritium regime. The joint GA-ORNL program on ISX continues to take shape with impurity flow reversal experiments scheduled for early FY 1978. Efforts within the plasma theory program concentrated on MHD equilibrium and stability theory with respect to noncircular tokamaks and, in addition, on the interpretation of experimental results and analysis of various auxiliary plasma heating schemes. The USC supported the various computational needs associated with the overall General Atomic program. The development and technology program carried out programs in the areas of particle and plasma interactions with surfaces, superconducting magnet development, and systems studies

Prefrontal cortex glutamate correlates with mental perspective-taking.

Directory of Open Access Journals (Sweden)

Christiane Montag

Full Text Available BACKGROUND: Dysfunctions in theory of mind and empathic abilities have been suggested as core symptoms in major psychiatric disorders including schizophrenia and autism. Since self monitoring, perspective taking and empathy have been linked to prefrontal (PFC and anterior cingulate cortex (ACC function, neurotransmitter variations in these areas may account for normal and pathological variations of these functions. Converging evidence indicates an essential role of glutamatergic neurotransmission in psychiatric diseases with pronounced deficits in empathy. However, the role of the glutamate system for different dimensions of empathy has not been investigated so far. METHODOLOGY/PRINCIPAL FINDINGS: Absolute concentrations of cerebral glutamate in the ACC, left dorsolateral PFC and left hippocampus were determined by 3-tesla proton magnetic resonance spectroscopy (1H-MRS in 17 healthy individuals. Three dimensions of empathy were estimated by a self-rating questionnaire, the Interpersonal Reactivity Index (IRI. Linear regression analysis showed that dorsolateral PFC glutamate concentration was predicted by IRI factor "perspective taking" (T = -2.710, p = 0.018; adjusted alpha-level of 0.017, Bonferroni but not by "empathic concern" or "personal distress". No significant relationship between IRI subscores and the glutamate levels in the ACC or left hippocampus was detected. CONCLUSIONS/SIGNIFICANCE: This is the first study to investigate the role of the glutamate system for dimensions of theory of mind and empathy. Results are in line with recent concepts that executive top-down control of behavior is mediated by prefrontal glutamatergic projections. This is a preliminary finding that needs a replication in an independent sample.

Clinical inertia is a failure to intensify treatment according to evidence-based guidelines, and can have both short- and long-term adverse effects for type 2 diabetes (T2D). The aim of the present study was to demonstrate the effects of clinical inertia on glycemic control and diabetes-related complications. A retrospective cohort study was conducted at a university-based hospital in Thailand. Medical records were evaluated retrospectively from January 2010 to December 2014. Patients were classified into two groups: clinical inertia and non-inertia. Clinical inertia was defined as failure to initiate insulin within 3 months in patients with HbA1c ≥9 % who were already taking two oral antidiabetic agents. From 1206 records, 98 patients with mean HbA1c of 10.3 % were identified and enrolled in the study. The median follow-up time of these patients was 29.5 months and 68.4 % were classified into the clinical inertia group. The mean (± SD) HbA1c decrement in the clinical inertia and non-inertia groups was 0.82 ± 1.50 % and 3.02 ± 1.80 %, respectively, at 6 months (P inertia was associated with a significantly shorter median time to progression of diabetic retinopathy (DR); log rank test, P = 0.02 and a higher incidence of DR progression (10 vs 2.2 cases per 1000 person-months; P = 0.003). The adjusted incidence rate ratio for DR progression in the clinical inertia group was 4.92 (95 % confidence interval 1.11-21.77; P = 0.036). Being treated by general practitioners was the strongest risk factor associated with clinical inertia. Clinical inertia can cause persistently poor glycemic control and speed up the progression of DR in T2D. © 2016 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

A group of pathological gamblers and a group of problem gamblers (i.e., gamblers at risk of becoming pathological) were compared to healthy controls on their risk-taking propensity after prior losses. Each participant played both the Balloon Analogue Risk Taking task (BART) and a modified version of the same task, where individuals face five repeated predetermined early losses at the onset of the game. No significant difference in risk-taking was found between groups on the standard BART task, while significant differences emerged when comparing behaviors in the two tasks: both pathological gamblers and controls reduced their risk-taking tendency after prior losses in the modified BART compared to the standard BART, whereas problem gamblers showed no reduction in risk-taking after prior losses. We interpret these results as a sign of a reduced sensitivity to negative feedback in problem gamblers which might contribute to explain their loss-chasing tendency.

Although high-risk sport participants are typically considered a homogenous risk-taking population, attitudes to risk within the high-risk domain can vary considerably. As no validated measure allows researchers to assess risk taking within this domain, we validated the Risk Taking Inventory (RTI) for high-risk sport across four studies. The RTI comprises seven items across two factors: deliberate risk taking and precautionary behaviors. In Study 1 (n = 341), the inventory was refined and tested via a confirmatory factor analysis used in an exploratory fashion. The subsequent three studies confirmed the RTI's good model-data fit via three further separate confirmatory factor analyses. In Study 2 (n = 518) and in Study 3 (n = 290), concurrent validity was also confirmed via associations with other related traits (sensation seeking, behavioral activation, behavioral inhibition, impulsivity, self-esteem, extraversion, and conscientiousness). In Study 4 (n = 365), predictive validity was confirmed via associations with mean accidents and mean close calls in the high-risk domain. Finally, in Study 4, the self-report version of the inventory was significantly associated with an informant version of the inventory. The measure will allow researchers and practitioners to investigate risk taking as a variable that is conceptually distinct from participation in a high-risk sport.

To classify medically treated open-angle glaucoma (OAG) by the pattern of progression using hierarchical cluster analysis, and to determine OAG progression characteristics by comparing clusters. Ninety-five eyes of 95 OAG patients who received medical treatment, and who had undergone visual field (VF) testing at least once per year for 5 or more years. OAG was classified into subgroups using hierarchical cluster analysis based on the following five variables: baseline mean deviation (MD), baseline visual field index (VFI), MD slope, VFI slope, and Glaucoma Progression Analysis (GPA) printout. After that, other parameters were compared between clusters. Two clusters were made after a hierarchical cluster analysis. Cluster 1 showed -4.06 ± 2.43 dB baseline MD, 92.58% ± 6.27% baseline VFI, -0.28 ± 0.38 dB per year MD slope, -0.52% ± 0.81% per year VFI slope, and all "no progression" cases in GPA printout, whereas cluster 2 showed -8.68 ± 3.81 baseline MD, 77.54 ± 12.98 baseline VFI, -0.72 ± 0.55 MD slope, -2.22 ± 1.89 VFI slope, and seven "possible" and four "likely" progression cases in GPA printout. There were no significant differences in age, sex, mean IOP, central corneal thickness, and axial length between clusters. However, cluster 2 included more high-tension glaucoma patients and used a greater number of antiglaucoma eye drops significantly compared with cluster 1. Hierarchical cluster analysis of progression patterns divided OAG into slow and fast progression groups, evidenced by assessing the parameters of glaucomatous progression in VF testing. In the fast progression group, the prevalence of high-tension glaucoma was greater and the number of antiglaucoma medications administered was increased versus the slow progression group.

To examine the associations between hormonal contraceptive use and measures of HIV disease progression and antiretroviral treatment (ART) effectiveness. A prospective cohort study of women with prevalent HIV infection in St. Petersburg, Russia, was conducted. After contraceptive counseling, participants chose to use combined oral contraceptives (COCs), depot-medroxyprogesterone acetate (DMPA), a copper intrauterine device (IUD) or male condoms for pregnancy prevention. Among participants not using ART at enrollment, we used multivariate Cox regression to assess the association between current (time-varying) contraceptive use and disease progression, measured by the primary composite outcome of CD4 decline to contraceptive method. During a total of 5233 months follow-up among participants not using ART with enrollment CD4 ≥350 cells/mm(3) (n=315), 97 experienced disease progression. Neither current use of COCs [adjusted hazard ratio (aHR) 0.91, 95% confidence interval (CI) 0.56-1.48] nor DMPA (aHR 1.28, 95% CI 0.71-2.31) was associated with a statistically significant increased risk for disease progression compared with use of nonhormonal methods (IUD or condoms). Among participants using ART at enrollment (n=77), we found no statistically significant differences in the predicted mean changes in CD4 cell count comparing current use of COCs (p=.1) or DMPA (p=.3) with nonhormonal methods. Hormonal contraceptive use was not significantly associated with measures of HIV disease progression or ART effectiveness among women with prevalent HIV infection. Hormonal contraceptive use was not significantly associated with measures of HIV disease progression or ART effectiveness among women with prevalent HIV infection. Published by Elsevier Inc.

Characterization of annual disease progression of multiple sclerosis patients: A population-based study

Previous research characterizing factors influencing multiple sclerosis (MS) disease progression has typically been based on time to disease milestones (Kaplan-Meier, Cox hazard regression, etc.). A limitation of these methods is the handling of the often large groups of patients not reaching...... the milestone. To characterize clinical factors influencing MS disease progression as annual transitions from each Expanded Disability Status Scale (EDSS). The annual progression of 11,964 patients from the Swedish MS Registry was analysed with 10 multinomial logistic regressions, that is, one for transition...... from each full EDSS with explanatory variables age, sex, age at onset, time in current EDSS, highest prior EDSS, MS course and treatment. All factors (except sex) investigated had statistically significant impacts on transitions from at least one EDSS. However, significance and size of the effect...

Our research analyzes the effect of the traders’ subjective risk attitude, optimism and overconfidence on their risk taking behaviors on the Chinese Stock Market by experimental study method. We find that investors’ risk taking behavior is significantly affected by their subjective risk attitude, optimism and overconfidence. Our results also argue that the objective return and volatility of stock are not as good predictors of risk taking behavior as subjective risk and return measures. Moreover, we illustrate that overconfidence and optimism have an significant impact on risk taking behavior In line with theoretical models.

With a 5-year survival rate of <5%, pancreatic cancer is one of the most rapidly fatal malignancies. Current protocols for the treatment of pancreas cancer are not as effective as we desire. In this study, we show that a novel Mucin-1 (MUC1)-based vaccine in combination with a cyclooxygenase-2 inhibitor (celecoxib), and low-dose chemotherapy (gemcitabine) was effective in preventing the progression of preneoplastic intraepithelial lesions to invasive pancreatic ductal adenocarcinomas. The study was conducted in an appropriate triple transgenic model of spontaneous pancreatic cancer induced by the KRASG12D mutation and that expresses human MUC1 as a self molecule. The combination treatment elicited robust antitumor cellular and humoral immune responses and was associated with increased apoptosis in the tumor. The mechanism for the increased immune response was attributed to the down-regulation of circulating prostaglandin E2 and indoleamine 2, 3,-dioxygenase enzymatic activity, as well as decreased levels of T regulatory and myeloid suppressor cells within the tumor microenvironment. The preclinical data provide the rationale to design clinical trials with a combination of MUC1-based vaccine, celecoxib, and gemcitabine for the treatment of pancreatic cancer. PMID:19109152

The role of technical progress in the process of recalculating oil reserves

International Nuclear Information System (INIS)

Boulard, J.N.

1999-01-01

Contrary to the concept of resources (which is essentially a geological one), the notion of reserves designates the quantities that are technically and economically recoverable. Beyond the production-related effect, the reserves therefore evolve over time in accordance with numerous technical and economic parameters. Among these parameters, it can be seen that technical progress plays a considerable role throughout the process of converting resources into reserves, including progress in the identification, accessibility and processing of the resources, and improvements in economic viability. After having tackled the problem of measuring the 'technical progress effects' and citing examples, we demonstrate that the evolution in oil reserves is subject to three types of impact. These are a quantitative impact by significantly improving the recovery rates or making it possible to identify hitherto undetectable oil fields, a qualitative impact by widening the resource base thanks to the adoption of new categories of oil (in particular the so-called 'unconventional' oils) and by carrying out the gradual substitution between these resources of differing qualities. There is also a dynamic impact, through the acceleration of resource availability. Through these three approaches, technical progress makes makes it possible to ensure continuity in oil supply and contributes significantly to the recalculation of reserves. It therefore acts as a compensating factor, counterbalancing the progressive depletion of resources. (author)

Take back program for ICN products - a B2B solution for WEEE implementation

Energy Technology Data Exchange (ETDEWEB)

Renner, H. [Siemens ICN, Munich (Germany); Chryssos, G. [eds-r GmbH, Thierhaupten (Germany)

2004-07-01

In 2005 the WEEE (waste electrical and electronic equipment) directive has to be implemented in each country of the European Union. The implementation of this directive affects a significant part of end of life equipment which has to be taken back directly from B2B (business to business) users. In contrast to end of life equipment from private households, there is a high residual value and therefore high reuse potential of B2B equipment. Within this scope a take back program for telecommunications equipment has been implemented by Siemens ICN together with the recycling company and re-use expert eds-r GmbH in order to optimise recovery and take back logistics processes. Essential elements of this take back program are area-wide take back logistics with web based track and trace system, professional dismantling and selection of reusable components with subsequent redelivery to service and sales network of Siemens ICN as well as professional recovery.

In previous work assessing memory at various levels of representation, namely the surface form, textbase, and situation model levels, participants read texts but were otherwise not actively engaged with the texts. The current study tested the influence of active engagement with the material via note taking, along with the opportunity to review such notes, and the modality of presentation (text vs. spoken). The influence of these manipulations was assessed both immediately and 1 week later. In Experiment 1 participants read a text, whereas in Experiment 2 participants watched a video recording of the material being read as a lecture. For each experiment the opportunity to take notes was manipulated within participants, and the opportunity to review these notes before the test was manipulated between participants. Note taking improved performance at the situation model level in both experiments, although there was also some suggestion of benefit for the surface form. Thus, active engagement with material, such as note taking, appears to have the greatest benefit at the deeper levels of understanding.

Parapapillary atrophy (PPA) progression has been associated with progressive glaucoma, but has proven to be difficult to assess clinically. We compared inter- and intra-observer agreement using a novel automated alternation flicker technology and side-by-side digital photography inspection for the evaluation of PPA progression. Consecutive patients with serial digital optic nerve photographs at least 1 year apart were included. Two graders (NR, BV) masked to image chronology assessed a set of photographs for progressive PPA using predefined criteria based on reference photographs containing mild, moderate, extensive or no PPA progression. At a separate session, the graders evaluated photographs using alternation flicker (EyeIC, Narberth, PA, USA) applying the same criteria. The order of patients and technique was randomized. Graders then assessed the same set of flickers and photographs a second time with the order of presentation reversed. The main outcome measure was the assessment of progressive PPA as identified by alternation flicker and digital photography inspection. Inter- and intra-observer agreement using each technique was assessed using the kappa statistic. A bootstrap method for comparing correlated kappa coefficients was used to assess statistical significance. Serial photographs from 131 eyes of 68 patients were evaluated. Both graders identified significantly more cases of PPA progression using flicker compared to photography (27-34% vs 8-13%; both pphotographs (kappa=0.52 vs 0.18, p=0.02). Intra-observer agreement was similar for both graders (photos: kappa=0.58 vs 0.57, p=0.97; flicker: kappa=0.61 vs 0.70, p=0.37). When progression was assessed by the number of progressive quadrants identified by each grader using a weighted kappa statistic, flicker inter-observer agreement was still moderate (kappa=0.45) and significantly better (p=0.01) than photography, which showed poor agreement (kappa=0.15). Intra-observer agreement with a weighted kappa for

To investigate the longitudinal spinal cord and brain changes in neuromyelitis optica (NMO) and multiple sclerosis (MS) and their associations with disability progression. We recruited 28 NMO, 22 MS, and 20 healthy controls (HC), who underwent both spinal cord and brain MRI at baseline. Twenty-five NMO and 20 MS completed 1-year follow-up. Baseline spinal cord and brain lesion loads, mean upper cervical cord area (MUCCA), brain, and thalamus volume and their changes during a 1-year follow-up were measured and compared between groups. All the measurements were also compared between progressive and non-progressive groups in NMO and MS. MUCCA decreased significantly during the 1-year follow-up in NMO not in MS. Percentage brain volume changes (PBVC) and thalamus volume changes in MS were significantly higher than NMO. MUCCA changes were significantly different between progressive and non-progressive groups in NMO, while baseline brain lesion volume and PBVC were associated with disability progression in MS. MUCCA changes during 1-year follow-up showed association with clinical disability in NMO. Spinal cord atrophy changes were associated with disability progression in NMO, while baseline brain lesion load and whole brain atrophy changes were related to disability progression in MS. (orig.)

Governments cut takes to compete as world acreage demand falls

International Nuclear Information System (INIS)

Meurs, A.P. van

1995-01-01

During the last decade there has been significant change in fiscal terms and conditions applicable to petroleum exploration and production. An analysis of 226 fiscal systems in 144 countries indicates that there has been a substantial downward trend in government take. Of the 226 fiscal systems analyzed, 130 were changed during the last decade. The changes resulted in a lower government take in almost all cases. During the last decade the supply of exploration acreage has increased due to the fact that a large number of countries decided to open new areas. A number of other countries decided to accelerate the process of offering acreage. In total, the acreage available for exploration by private oil companies almost doubled during the last 10 years. At the same time the demand for acreage has been reduced due to lower oil prices and reduced oil industry cash flows. As a result, the ''price'' for acreage--in terms of government take--has declined. This development has created a new situation in which governments are now strongly competing for exploration and development investments. The question is, how do governments compete and what is the current status of the competition? The process of competition among governments is still poorly understood by governments and companies. The paper attempts to explain

Alzheimer\\'s Disease (AD) is currently attracting much attention in elders\\' care. As the increasing availability of massive clinical diagnosis data, especially the medical images of brain scan, it is highly significant to precisely identify and predict the potential AD\\'s progression based on the knowledge in the diagnosis data. In this paper, we follow a novel sequential learning framework to model the disease progression for AD patients\\' care. Different from the conventional approaches using only initial or static diagnosis data to model the disease progression for different durations, we design a score-involved approach and make use of the sequential diagnosis information in different disease stages to jointly simulate the disease progression. The actual clinical scores are utilized in progress to make the prediction more pertinent and reliable. We examined our approach by extensive experiments on the clinical data provided by the Alzheimer\\'s Disease Neuroimaging Initiative (ADNI). The results indicate that the proposed approach is more effective to simulate and predict the disease progression compared with the existing methods.

A major success was achieved this year by the West Valley Demonstration Project in New York, which in June completed the project's production phase of high-level waste processing ahead of schedule and under budget. Another significant accomplishment this year was the award of two privatization contracts for major waste management operations, one at Oak ridge for transuranic waste treatment, and one at Hanford for the Tank Waste Remediation System privatization project. DOE is proud of the progress that has been made, and will continue to pursue program activities that allow it to safely and expeditiously dispose of radioactive and hazardous wastes across the complex, while reducing worker, public, and environmental risks

Background: The recent and rapidly popularized social phenomenon of selfie taking has been showing an increasing trend. It is thus imperative to assess the knowledge, attitude, and perception of the groups toward this phenomenon. Selfie taking is associated with younger age groups and hence, we aimed to explore the attitudes toward selfie taking and its relation toward body image and narcissism in medical college students. Methodology: This was cross-sectional study and had two groups with Group A comprising 92 first year medical students and Group B including 103 postgraduate (PG) medical students from various specialties. They were interviewed in a single session using the scale of attitude toward selfie-taking questionnaire, Body Image Acceptance and Action Questionnaire (BIAAQ), and the narcissistic personality inventory. Scores obtained were computed using basic descriptive statistics and t-test where appropriate. Results: A strong positive favorable trend toward selfie taking was noticed among both groups (A = 56.5%, B = 45.6%). There was no difference in attitude between the two groups, or difference in the gender between those clicking their own selfies regularly within each group. BIAAQ reflected a significant difference among male subjects of the two groups with PG students was more concerned about body image (P = 0.001), whereas female subjects of both groups showed no such difference. The narcissism traits also showed a significant difference, only when males of both groups were compared again in favor of PG medical students (P = 0.022). Conclusion: This study revealed that selfie-taking is popular among medical students both in their undergraduate and PG period. Further research in diverse clinical and nonclinical populations is warranted to explore the relation between this phenomenon and body image acceptance or narcissistic traits. PMID:29403124

On 27 March 2013, the European Commission published its first Renewable Energy Progress Report under the framework of the 2009 Renewable Energy Directive. Since the adoption of this directive and the introduction of legally binding renewable energy targets, most Member States experienced significant growth in renewable energy consumption. 2010 figures indicate that the EU as a whole is on its trajectory towards the 2020 targets with a renewable energy share of 12.7%. Moreover, in 2010 the majority of Member States already reached their 2011/2012 interim targets set in the Directive. However, as the trajectory grows steeper towards the end, more efforts will still be needed from the Member States in order to reach the 2020 targets. With regard to the EU biofuels and bioliquids sustainability criteria, Member States' implementation of the biofuels scheme is considered too slow. In accordance with the reporting requirements set out in the 2009 Directive on Renewable Energy, every two years the European Commission publishes a Renewable Energy Progress Report. The report assesses Member States' progress in the promotion and use of renewable energy along the trajectory towards the 2020 renewable energy targets. The report also describes the overall renewable energy policy developments in each Member State and their compliance with the measures outlined in the Directive and the National Renewable Energy Action Plans. Moreover, in accordance with the Directive, it reports on the sustainability of biofuels and bioliquids consumed in the EU and the impacts of this consumption. A consortium led by Ecofys was contracted by the European Commission to perform support activities concerning the assessment of progress in renewable energy and sustainability of biofuels.

Most educators consider note-taking a critical component of formal classroom learning. Advancements in technology such as tablet computers, mobile applications, and recorded lectures are altering classroom dynamics and affecting the way students compose and review class notes. These tools may improve a student's ability to take notes, but they also may hinder learning. In an era of dynamic technology developments, it is important for educators to routinely examine and evaluate influences on formal and informal learning environments. This paper discusses key background literature on student note-taking, identifies recent trends and potential implications of mobile technologies on classroom note-taking and student learning, and discusses future directions for note-taking in the context of digitally enabled lifelong learning.

This study explored relationships between perspective-taking, emotion understanding, and children's narrative abilities. Younger (23 5-/6-year-olds) and older (24 7-/8-year-olds) children generated fictional narratives, using a wordless picture book, about a frog experiencing jealousy. Children's emotion understanding was assessed through a standardized test of emotion comprehension and their ability to convey the jealousy theme of the story. Perspective-taking ability was assessed with respect to children's use of narrative evaluation (i.e., narrative coherence, mental state language, supplementary evaluative speech, use of subjective language, and placement of emotion expression). Older children scored higher than younger children on emotion comprehension and on understanding the story's complex emotional theme, including the ability to identify a rival. They were more advanced in perspective-taking abilities, and selectively used emotion expressions to highlight story episodes. Subjective perspective taking and narrative coherence were predictive of children's elaboration of the jealousy theme. Use of supplementary evaluative speech, in turn, was predictive of both subjective perspective taking and narrative coherence. ©2010 The British Psychological Society.

Dietary folate is essential in all tissues to maintain several metabolite pools and cellular proliferation. Prostate cells, due to specific metabolic characteristics, have increased folate demand to support proliferation and prevent genetic and epigenetic damage. Although several studies have found that dietary folate interventions can affect colon cancer biology in rodent models, its impact on prostate is unknown. The purpose of this study was to determine whether dietary folate manipulation, possibly being of primary importance for prostate epithelial cell metabolism, could significantly affect prostate cancer progression. Strikingly, mild dietary folate depletion arrested prostate cancer progression in 25 of 26 transgenic adenoma of the mouse prostate (TRAMP) mice, in which tumorigenesis is prostate-specific and characteristically aggressive. The significant effect on prostate cancer growth was characterized by size, grade, proliferation, and apoptosis analyses. Folate supplementation had a mild, nonsignificant, beneficial effect on grade. In addition, characterization of folate pools (correlated with serum), metabolite pools (polyamines and nucleotides), genetic and epigenetic damage, and expression of key biosynthetic enzymes in prostate tissue revealed interesting correlations with tumor progression. These findings indicate that prostate cancer is highly sensitive to folate manipulation and suggest that antifolates, paired with current therapeutic strategies, might significantly improve treatment of prostate cancer, the most commonly diagnosed cancer in American men.

Factors influencing nurse and pharmacist willingness to take or not take responsibility for non-medical prescribing.

In the UK, the majority of non-medical prescribers (NMPs) are nurses or pharmacists working in community or primary care. However, little is known about what influences their decisions to prescribe, unlike with medical prescribing. It is also unclear whether the medical findings can be extrapolated, given their very different prescribing training. To explore the factors influencing whether nurse and pharmacist NMPs in community and primary care settings take responsibility for prescribing. Initially, 20 NMPs (15 nurses and 5 pharmacists) were purposively selected and interviewed using the critical incident technique about situations where they felt it was inappropriate for them to take responsibility for prescribing or where they were uneasy about doing so. In addition, more general factors influencing their decision to take or not take prescribing responsibility were discussed. Subsequently, the themes from the interview analysis were validated in three focus groups with a total of 10 nurse NMPs. All data were analyzed using a constant comparison approach. Fifty-two critical incidents were recorded--12 from pharmacist NMPs and 40 from nurse NMPs. Participants experienced situations where they were reluctant to accept responsibility for prescribing. Perceptions of competency, role and risk influenced their decision to prescribe. Workarounds such as delaying the prescribing decision or refer the patient to a doctor were used. For NMPs to feel more confident about taking responsibility for prescribing, these issues of competency, role and perceived risk need to be addressed. Roles of NMPs must be clear to colleagues, doctors and patients. Training and support must be provided to enable professional development and increasing competence of NMPs.

We argue that personal (e.g., age, gender and education) and circumstantial (e.g., bureaucratic rank and sector of employment) factors affect the cost and the benefit of bribe-taking by the bureaucrats. The bureaucrat’s bribe-taking decision is modeled. A unique data set is used to test the predictions of the model. The empirical findings include that education reduces, but power (measured by rank and sector of work) increases, the magnitude of bribe-taking. Age affects bribe-taking in a ...

Purpose: The 1-year local control rates after single-fraction stereotactic radiotherapy (SRT) for brain metastases > 3 cm diameter are less than 70%, but with fractionated SRT (FSRT) higher local control rates have been reported. The purpose of this study was to compare our treatment results with SRT and FSRT for large brain metastases. Materials and methods: In two consecutive periods, 41 patients with 46 brain metastases received SRT with 1 fraction of 15 Gy, while 51 patients with 65 brain metastases received FSRT with 3 fractions of 8 Gy. We included patients with brain metastases with a planning target volume of > 13 cm{sup 3} or metastases in the brainstem. Results: The minimum follow-up of patients still alive was 22 months. Comparing 1 fraction of 15 Gy with 3 fractions of 8 Gy, the 1-year rates of freedom from any local progression (54% and 61%, p = 0.93) and pseudo progression (85% and 75%, p = 0.25) were not significantly different. Overall survival rates were also not different. Conclusion: The 1-year local progression and pseudo progression rates after 1 fraction of 15 Gy or 3 fractions of 8 Gy for large brain metastases and metastases in the brainstem are similar. For better local control rates, FSRT schemes with a higher biological equivalent dose may be necessary. (orig.)

Hip arthroscopy allows surgeons to address intra-articular pathology of the hip while avoiding more invasive open surgical dislocation. However the post-operative rehabilitation protocols have varied greatly in the literature, with many having prolonged periods of limited motion and weight bearing. The purpose of this study was to describe a criterion-based early weight bearing protocol following hip arthroscopy and investigate functional outcomes in the subjects who were active duty military. Active duty personnel undergoing hip arthroscopy for symptomatic femoroacetabular impingement were prospectively assessed in a controlled environment for the ability to incorporate early postoperative weight-bearing with the following criteria: no increased pain complaint with weight bearing and normalized gait pattern. Modified Harris Hip (HHS) and Hip Outcome score (HOS) were performed preoperatively and at six months post-op. Participants were progressed with a standard hip arthroscopy protocol. Hip flexion was limited to not exceed 90 degrees for the first three weeks post-op, with progression back to running beginning at three months. Final discharge was dependent upon the ability to run two miles at military specified pace and do a single leg broad jump within six inches of the contralateral leg without an increase in pain. Eleven participants met inclusion criteria over the study period. Crutch use was discontinued at an average of five days following surgery based on established weight bearing criteria. Only one participant required continued crutch use at 15 days. Participants' functional outcome was improved postoperatively, as demonstrated by significant increases in HOS and HHS. At the six month follow up, eight of 11 participants were able to take and complete a full Army Physical Fitness Test. Following completion of the early weight bearing rehabilitation protocol, 81% of participants were able to progress to full weight bearing by four days post

This paper investigates the political maneuvering that accompanies subsidiary initiative taking in multinational corporations. On the basis of an explorative empirical investigation of subsidiary initiative taking in the French subsidiaries of six German MNCs, the paper explores the activities...... that subsidiaries undertake to sell their initiatives, and the relationships among issue selling, subsidiary power and headquarters’ hierarchical power. The findings suggest that the use of issue-selling tactics is common when subsidiaries engage in initiative taking. In addition, the paper demonstrates that a low...... degree of issue selling is needed to obtain approval of an initiative in less asymmetrical headquarters–subsidiary power relationships (i.e. relationships in which subsidiaries are relatively powerful). In cases where power relationships are highly asymmetrical, issue selling is a necessity...

Patients with progressive multiple sclerosis (MS) often have cognitive impairment in addition to physical impairment. The burden of cognitive and physical impairment progresses over time, and may be major determinants of quality of life. The aim of this study was to assess to which degree quality of life correlates with physical and cognitive function in progressive MS. This is a retrospective study of 52 patients with primary progressive ( N  = 18) and secondary progressive MS ( N  = 34). Physical disability was assessed using the Expanded Disability Status Scale, Timed 25 Foot Walk (T25FW) test and 9-Hole Peg Test (9HPT). Cognitive function was assessed using Symbol Digit Modalities Test (SDMT), Paced Auditory Serial Addition Test, and Trail Making Test B (TRAIL-B). In addition, quality of life was assessed by the Short Form 36 (SF-36) questionnaire. Only measures of cognitive function correlated with the overall SF-36 quality of life score and the Mental Component Summary score from the SF-36. The only physical measure that correlated with a measure of quality of life was T25FW test, which correlated with the Physical Component Summary from the SF-36. We found no other significant correlations between the measures of cognitive function and the overall physical measures but interestingly, we found a possible relationship between the 9HPT score for the nondominant hand and the SDMT and TRAIL-B. Our findings support inclusion of measures of cognitive function in the assessment of patients with progressive MS as these correlated closer with quality of life than measures of physical impairment.

We conducted a simple resource allocation game known as the ultimatum game (UG) with preschoolers to examine the role of cognitive and emotional perspective-taking ability on allocation and rejection behavior. A total of 146 preschoolers played the UG and completed a false belief task and an emotional perspective-taking test. Results showed that cognitive perspective taking ability had a significant positive effect on the proposer's offer and a negative effect on the responder's rejection behavior, whereas emotional perspective taking ability did not impact either the proposer's or responder's behavior. These results imply that the ability to anticipate the responder's beliefs, but not their emotional state, plays an important role in the proposer's choice of a fair allocation in an UG, and that children who have not acquired theory of mind still reject unfair offers.

The present study examined the relations between different empathic dimensions and bystanders' behavior in bullying. Specifically, the indirect effects of empathic concern and perspective taking via empathic anger on defending and passive bystanding were tested in a sample of Italian young adolescents (N = 398; M age  = 12 years, 3 months, 47.2% girls). Path analysis confirmed the direct and indirect effects, via empathic anger, of empathic concern and perspective taking on bystanders' behavior, with the exception of the direct association between perspective taking and passive bystanding that was not significant. Our findings suggest that considering empathic anger together with empathic concern and perspective taking could help researchers to better understand the links between empathic dispositions and bystanders' behavior in bullying.

To examine whether an intervention on proper use of electronic medical records (EMRs) in patient care could help improve medical students' empathic engagement, and to test the hypothesis that the training would reduce communication hurdles in clinical encounters. Seventy third-year medical students from the Sidney Kimmel Medical College at Thomas Jefferson University were randomly divided into intervention and control groups during their six-week pediatric clerkship in 2012-2013. The intervention group received a one-hour training session on EMR-specific communication skills, including discussion of EMR use, the SALTED mnemonic and technique (Set-up, Ask, Listen, Type, Exceptions, Documentation), and role-plays. Both groups completed the Jefferson Scale of Empathy (JSE) at the clerkship's start and end. At clerkship's end, faculty and standardized patients (SPs) rated students' empathic engagement in SP encounters, using the Jefferson Scale of Patient Perceptions of Physician Empathy (JSPPPE), and their history-taking and communication skills. Faculty mean ratings on the JSPPPE, history-taking skills, and communication skills were significantly higher for the intervention group than the control group. SP mean ratings on history-taking skills were significantly higher for the intervention group than the control group. Both groups' JSE mean scores increased pretest to posttest, but the changes were not significant. The intervention group's posttest JSE mean score was higher than the control group's, but the difference was not significant. The findings suggest that a simple intervention providing specialized training in EMR-specific communication can improve medical students' empathic engagement in patient care, history-taking skills, and communication skills.
