    Background: The present study was conducted to assess the relationship between drinking water fluoride (F) levels, dental fluorosis and dental caries among 9-12 years old school children of Nelakondapally Mandal, Khammam district, Andhra Pradesh. Materials and Methods: A cross-sectional analytical study was conducted on 1500 school children aged 9-12 years, selected by stratified random sampling from different areas with different levels of naturally occurring F in drinking water. The children were assessed for dental fluorosis according to WHO basic survey guidelines. The overall oral health status of the child was assessed by decayed missing filled teeth (DMFT)/dmft index. Statistical analysis was done using mean, standard deviation, standard error, Z-test, ANOVA test, and Chi-square test. Results: The results of the present study revealed that the prevalence of fluorosis was 74.9%. Number of children having dental fluorosis was highest in children who consume water from bore wells. Caries prevalence in the study population was about 56.5%. Caries prevalence and mean DMFT/dmft scores were least in children with optimal F areas and highest in children with below optimal F areas. Conclusion: There was moderate prevalence of fluorosis in Nelakondapally Mandal of Khammam district, and caries prevalence is high in areas below optimal F areas.

  18. Effects of a rise in base level on graded streams

    SciTech Connect

    Dickfoss, P.V. . Geology Dept.)

    1994-04-01

    What changes take place in a longitudinal river profile due to a rise in base level would seem to be a fundamental question in geomorphology, however, little has been accomplished toward answering this question, and the prevailing views are contradictory. Most authors say that a river will adjust its entire profile in response to a rise in base level. This misconception appears to have started in Elmo G. Harris' 1901 article, Effects of Dams and Like Obstructions in Silt-bearing Streams. The hypothesis became popular after publication of J. Hoover Mackin's classic 1948 paper, Concept of the Graded River. In the section Rise of Base Level'' Mackin explained that ''...the only generalization that can be made is that the new profile will be everywhere adjusted to the new prevailing conditions.'' Although Mackin's idea was a conceptual one, the concept has subsequently been taken literally. Contrary to this perception, the small amount of work that has been completed shows rivers will adjust their profiles only a short distance upstream from reservoir level. This may be due to the adjustment becoming infinitesimally small upstream and grading into the original profile so that the adjustment upstream is negligible. Unfortunately the misconception of stream aggradation in response to a rise in base level has prevailed for over 90 years and is widespread in the literature. Many textbooks, both introductory and advanced, from 1971 to the present, and some of the leading names in geomorphology have accepted the misconception without question.

  7. Graded safeguards: Determination of attractiveness levels for special nuclear material

    SciTech Connect

    Wilkey, D.D.; Crawford, D.W.

    1994-08-01

    The DOE graded safeguards approach--as described in DOE Order 5633.3A, Control and Accountability of Nuclear Materials, and its guide--requires the determination of category levels of nuclear material locations to establish protection requirements for these locations. A critical parameter related to category determination is knowledge of the attractiveness level of the nuclear material with respect to use in a nuclear explosive device. DOE Order 5633.3A and its guide provide the policy basis for determining the attractiveness level of various forms and types of special nuclear material (SNM); however, these requirements and guidance are necessarily general and sometimes based on arbitrary criteria. Currently, there are large quantities of nuclear material on inventory within the DOE that need attractiveness determinations to ensure appropriate protection controls. Specific forms of these materials include materials in matrices requiring special processing, irradiated SNM that does not meet criteria for self-protecting, low concentration SNM, SNM as numerous small items, and bulk non-portable SNM items. This paper discusses the technical basis for applying material concentration limits for solids and liquids that can influence the various factors and criteria affecting the attractiveness level of SNM. Holdup and rollup considerations for determining category levels will be discussed as well.

  17. Grade level and achievement of immigrants’ children: academic redshirting in Hong Kong

    PubMed Central

    2014-01-01

    Data from Hong Kong PISA 2003 show that 15-year-old Hong Kong students who have immigrant parents from mainland China are grossly overrepresented in grades below the modal grade attended by most native Hong Kong students. Same-age comparison, when grade level is not taken into account, puts immigrants’ children at a disadvantaged position in the mathematics, reading, and science literacy tests. The academic advantage of immigrants’ children in Hong Kong is only revealed after grade is statistically controlled. Also, mainland immigrant students who are repeaters outperform native Hong Kong repeaters. Immigrant redshirting is a possible driving force behind these results. PMID:25214810

    Heath, Bruce E.; Crier, tomyka

    2003-01-01

    With the advancements in the computing power of personal computers, pc-based flight simulators and trainers have opened new avenues in the training of airplane pilots. It may be desirable to have the flight simulator make a quantitative evaluation of the progress of a pilot's training thereby reducing the physical requirement of the flight instructor who must, in turn, watch every flight. In an experiment, University students conducted six different flights, each consisting of two level turns. The flights were three minutes in duration. By evaluating videotapes, two certified flight instructors provided separate letter grades for each turn. These level turns were also evaluated using two other computer based grading methods. One method determined automated grades based on prescribed tolerances in bank angle, airspeed and altitude. The other method used was deviations in altitude and bank angle for performance index and performance grades.

  13. Factors in seventh grade academics associated with performance levels on the tenth grade biology end of course test in selected middle and high schools in northwest Georgia

    NASA Astrophysics Data System (ADS)

    Ward, Jennifer Henry

    This study attempted to identify factors in seventh grade academics that are associated with overall success in tenth grade biology. The study addressed the following research questions: Are there significant differences in performance levels in seventh grade Criterion Referenced Competency Test (CRCT) scores in science, math, reading, and language arts associated with performance categories in tenth grade biology End of Course Test (EOCT) and the following demographic variables : gender, ethnicity, socioeconomic status, disability category, and English language proficiency level? Is there a relationship among the categorical variables on the tenth grade biology EOCT and the same five demographic variables? Retrospective causal comparative research was used on a representative sample from the middle schools in three North Georgia counties who took the four CRCTs in the 2006-2007 school year, and took the biology EOCT in the 2009-2010 school year. Chi square was used to determine the relationships of the various demographic variables on three biology EOCT performance categories. Twoway ANOVA determined relationships between the seventh grade CRCT scores of students in the various demographic groups and their performance levels on the biology EOCT. Students' performance levels on the biology EOCT matched their performance levels on the seventh grade CRCTs consistently. Females performed better than males on all seventh grade CRCTs. Black and Hispanic students did worse than White and Asian/Asian Indian students on the math CRCT. Students living in poverty did worse on reading and language arts CRCTs than students who were better off. Special education students did worse on science, reading, and language arts CRCTs than students not receiving special education services. English language learners did worse than native English speakers on all seventh grade CRCTs. These findings suggest that remedial measures may be taken in the seventh grade that could impact

  14. Prediction of the Grade of Acute Cholecystitis by Plasma Level of C-Reactive Protein

    PubMed Central

    Kabul Gurbulak, Esin; Gurbulak, Bunyamin; Akgun, Ismail Ethem; Duzkoylu, Yigit; Battal, Muharrem; Fevzi Celayir, Mustafa; Demir, Uygar

    2015-01-01

    Background: Acute cholecystitis is the most common complication of gallbladder stones. Today, Tokyo guidelines criteria are recommended for diagnosis, grading, and management of acute cholecystitis. Objectives: We aimed to evaluate the levels of C-reactive protein (CRP) at different cut-off values to predict the severity of the disease and its possible role in grading the disease with regard to the guideline. Patients and Methods: This is a retrospective study, analyzing 682 cases out of consecutive 892 patients with acute cholecystitis admitted to two different general surgery clinics in Istanbul, Turkey. Records of patients diagnosed with acute cholecystitis were screened retrospectively from the hospital computer database between January 2011 and July 2014. A total of 210 patients with concomitant diseases causing high CRP levels were excluded from the study. The criteria of Tokyo guidelines were used in grading the severity of acute cholecystitis, and patients were divided into 3 groups. CRP values at the time of admission were analyzed and compared among the groups. Results: Mean CRP levels of groups were found to be significantly different, 18.96 mg/L in Group I, 133.51 mg/L in Group II, and 237.23 mg/L in Group III (P < 0.001). Having examined CRP values among the groups, they were found to be highly and significantly correlated with the disease grade (P < 0.0001). After evaluating CRP levels according to the grade of the disease, group 2 was distinguished from group 1 with a cut-off CRP level of 70.65 mg/L, and from group 3 with a value of 198.95 mg/L. Those results were found to be statistically significant (P < 0.001). Conclusions: CRP, a well-known acute phase reactant that increases rapidly in various inflammatory processes, can be accepted as a strong predictor in classifying different grades of the disease, and treatment can be reliably planned according to this classification.

    Wang, Lei; Zhang, Ronghui; Clarke, David; Wang, Weizhen

    2014-04-01

    Enactment of scientific inquiry in classroom has attracted a great attention of science educators around the world. In this study, we examined two competent teachers' (one Grade 9 chemistry teacher and one Grade 4 science teacher) enactment of scientific inquiry in selected teaching units to reveal the characteristics of enacted inquiry at different grade levels by analyzing lesson sequence videos. The coding schemes for enacted inquiry consist of ontological properties and instructional practices. Pre-topic and post-topic teacher interviews and the two teachers' responses to a questionnaire were adopted to identify the factors influencing teacher's enactment. The results indicate that the two case teachers' enactment involved a range of inquiry activities. The enacted inquiry at fourth-grade level covered all the inquiry elements, tending to engage students in the whole procedure of inquiry. The ninth-grade chemistry class placed emphasis on the elements "making plans" to solve problems in authentic context. Important factors influencing the enactment include teacher's understanding about scientific inquiry, textbooks, assessment, students and resource. Implications for inquiry enactment and instruction improvement have been provided.

    The present study was conducted to evaluate the level of food safety protection provided to consumers of Grade "A" milk and milk products in the United States by the National Conference on Interstate Milk Shipments (NCIMS) Grade "A" Milk Safety Program through its implementation and enforcement of the U.S. Grade "A" Pasteurized Milk Ordinance (PMO). The number of reported illnesses associated with Grade "A" milk and milk products in the United States was obtained from state and federal agencies and published articles. The consumption of Grade "A" milk and milk products in the United States was estimated from food consumption survey data for individuals. The level of food safety protection was measured quantitatively using the metric of annual illness attack rate. During a 15-year period (1999 through 2013), the estimated annual illness attack rate was 0.41 reported illnesses per 1 billion exposures (estimated using person-day intake data) or 0.52 reported illnesses per 1 billion lb (454 million kg) of Grade "A" milk and milk products consumed. Food safety protection provided to consumers of Grade "A" milk and milk products by the NCIMS through its implementation and enforcement of the PMO is important given the common consumption of Grade "A" milk and milk products in the United States.

    Connectivity in a gene-gene network declines with age, typically within gene clusters. We explored the effect of short-term (3 months) graded calorie restriction (CR) (up to 40 %) on network structure of aging-associated genes in the murine hypothalamus by using conditional mutual information. The networks showed a topological rearrangement when exposed to graded CR with a higher relative within cluster connectivity at 40CR. We observed changes in gene centrality concordant with changes in CR level, with Ppargc1a, and Ppt1 having increased centrality and Etfdh, Traf3 and Abcc1 decreased centrality as CR increased. This change in gene centrality in a graded manner with CR, occurred in the absence of parallel changes in gene expression levels. This study emphasizes the importance of augmenting traditional differential gene expression analyses to better understand structural changes in the transcriptome. Overall our results suggested that CR induced changes in centrality of biological relevant genes that play an important role in preventing the age-associated loss of network integrity irrespective of their gene expression levels.

    Cheung, Derek

    2009-01-01

    The purpose of this quantitative study was to examine the interaction effect between grade level and gender with respect to students' attitudes toward chemistry lessons taught in secondary schools. The sample consisted of 954 chemistry students in grades Secondary 4-7 (approximately 16-19 years of age) in Hong Kong. Students' attitudes were surveyed using an attitude toward chemistry lessons scale (ATCLS), and subscale scores were produced on four dimensions: liking for chemistry theory lessons; liking for chemistry laboratory work; evaluative beliefs about school chemistry; and behavioral tendencies to learn chemistry. When the ATCLS data were subjected to two-way MANOVA, the interaction effect between grade level and gender on students' attitudes toward chemistry lessons was statistically significant. The interaction effect was attributable to scores on the theory lessons subscale and laboratory work subscale. Male students in Secondary 4 and 5 liked chemistry theory lessons more than their female counterparts. However, male students' liking for chemistry laboratory work declined when they progressed from Secondary 4 to Secondary 7; no such a significant decline in attitude toward chemistry laboratory work was found in females. Overall, both males and females were just marginally positive about chemistry lessons during the years of secondary schooling. Implications of these findings for curriculum design are discussed.

  19. Effects of multisensory resources on the achievement and science attitudes of seventh-grade suburban students taught science concepts on and above grade level

    NASA Astrophysics Data System (ADS)

    Roberts, Patrice Helen

    This research was designed to determine the relationships among students' achievement scores on grade-level science content, on science content that was three years above-grade level, on attitudes toward instructional approaches, and learning-styles perceptual preferences when instructional approaches were multisensory versus traditional. The dependent variables for this investigation were scores on achievement posttests and scores on the attitude survey. The independent variables were the instructional strategy and students' perceptual preferences. The sample consisted of 74 educationally oriented seventh-grade students. The Learning Styles Inventory (LSI) (Dunn, Dunn, & Price, 1990) was administered to determine perceptual preferences. The control group was taught seventh-grade and tenth-grade science units using a traditional approach and the experimental group was instructed on the same units using multisensory instructional resources. The Semantic Differential Scale (SDS) (Pizzo, 1981) was administered to reveal attitudinal differences. The traditional unit included oral reading from the textbook, completing outlines, labeling diagrams, and correcting the outlines and diagrams as a class. The multisensory unit included five instructional stations established in different sections of the classroom to allow students to learn by: (a) manipulating Flip Chutes, (b) using Electroboards, (c) assembling Task Cards, (d) playing a kinesthetic Floor Game, and (e) reading an individual Programmed Learning Sequence. Audio tapes and scripts were provided at each location. Students circulated in groups of four from station to station. The data subjected to statistical analyses supported the use of a multisensory, rather than a traditional approach, for teaching science content that is above-grade level. T-tests revealed a positive and significant impact on achievement scores (p < 0.0007). No significance was detected on grade-level achievement nor on the perceptual

  20. Expression of Telomeres in Astrocytoma WHO Grade 2 to 4: TERRA Level Correlates with Telomere Length, Telomerase Activity, and Advanced Clinical Grade12

    Cancer cells bypass replicative senescence, the major barrier to tumor progression, by using telomerase or alternative lengthening of telomeres (ALT) as telomere maintenance mechanisms (TMMs). Correlation between ALT and patient survival was demonstrated for high-grade astrocytomas. Transcription from subtelomeres produces telomeric repeat-containing RNA (TERRA), a natural inhibitor of telomerase activity (TA). This led us to evaluate correlations of TERRA and TMM with tumor grade and outcome in astrocytoma patients. SYBR Green real-time reverse transcription-polymerase chain reaction assays for quantitation of total and chromosome 2p and 18p specific TERRA levels were developed. Tumor samples from 46 patients with astrocytoma grade 2 to 4, tissue controls, and cell lines were assessed. TMMs were evaluated by measuring TA and by detecting long telomeres due to ALT. In glioblastoma multiforme (GBM) grade 4, total TERRA levels were similar to cell lines but 14-, 31-, and 313-fold lower compared with grade 3, grade 2, and nonmalignant tissue, respectively. Total TERRA levels differed from chromosomal levels. Low 2p TERRA levels correlated with dense promoter methylation of subtelomeric CpG islands, indicating that TERRA expression in gliomas may be chromosome specific and epigenetically regulated. Total TERRA levels correlated with diagnosis, with low or absent TA and the presence of ALT, and were tentatively associated with favorable patient prognosis in our cohort (P = .06). TA and short telomeres identified a subset of GBM with a median survival of only 14.8 months. TERRA and TA may be prognostic in astrocytic tumors. PMID:22348177

    2014-03-01

    In this article, we introduce ESCOLEX, the first European Portuguese children's lexical database with grade-level-adjusted word frequency statistics. Computed from a 3.2-million-word corpus, ESCOLEX provides 48,381 word forms extracted from 171 elementary and middle school textbooks for 6- to 11-year-old children attending the first six grades in the Portuguese educational system. Like other children's grade-level databases (e.g., Carroll, Davies, & Richman, 1971; Corral, Ferrero, & Goikoetxea, Behavior Research Methods, 41, 1009-1017, 2009; Lété, Sprenger-Charolles, & Colé, Behavior Research Methods, Instruments, & Computers, 36, 156-166, 2004; Zeno, Ivens, Millard, Duvvuri, 1995), ESCOLEX provides four frequency indices for each grade: overall word frequency (F), index of dispersion across the selected textbooks (D), estimated frequency per million words (U), and standard frequency index (SFI). It also provides a new measure, contextual diversity (CD). In addition, the number of letters in the word and its part(s) of speech, number of syllables, syllable structure, and adult frequencies taken from P-PAL (a European Portuguese corpus-based lexical database; Soares, Comesaña, Iriarte, Almeida, Simões, Costa, …, Machado, 2010; Soares, Iriarte, Almeida, Simões, Costa, França, …, Comesaña, in press) are provided. ESCOLEX will be a useful tool both for researchers interested in language processing and development and for professionals in need of verbal materials adjusted to children's developmental stages. ESCOLEX can be downloaded along with this article or from http://p-pal.di.uminho.pt/about/databases . PMID:23709164

    2009-10-01

    An experiment was conducted to determine melamine residual levels in the tissues of broiler chickens fed diets containing graded levels of melamine. Ten experimental diets were developed to contain 0, 2, 5, 10, 20, 50, 100, 200, 500, and 1,000 mg of melamine/kg of diet. Each diet was offered in 4 replicate cages (12 birds per cage) from d 1 to 42, followed by a 7-d feeding of a withdrawal diet that contained no melamine. On d 28, 42, and 49, one bird per replicate was killed and tissue samples from the breast meat, liver, and kidney were collected for the determination of residual melamine levels. Throughout the 42-d feeding period, feeding diets containing graded levels of melamine had no effect (P>0.05) on the weight gain, feed intake, feed conversion ratio, and mortality of broiler chickens. Residue levels of melamine in broiler tissues at d 28 and 42 were below the detection limit when the diets containedlevels increased (P<0.05) with the increasing levels of melamine in birds fed diets containing higher than 100 mg/kg. At d 42, a similar trend was observed in the kidney, but melamine was detected in breast meat and liver only in birds fed diets containing 500 and 1,000 mg of melamine/kg of diet. Melamine distribution varied (P<0.05) in different tissues, with the highest concentration in the kidney. A withdrawal period of 7 d was found to clear the tissues of melamine. PMID:19762871

    Barnes, J. Aaron

    2015-01-01

    Background: Patient education is one of the key components required for patients to participate in decision making for their care. Sources of information should be complete and understandable. The objective of this study was to assess the quality and reading grade level of freely available materials pertaining to the evaluation and treatment of thyroid nodules. Methods: All available materials were gathered through a comprehensive Internet search or direct contact with each identified organization associated with thyroid care. Materials meeting inclusion criteria were assessed for completeness of content and reading grade level using the SMOG readability formula. Then, the DISCERN instrument was utilized to assess the quality of the five materials which had the best (lowest) and the five materials that had the worst (highest) SMOG reading grade levels. Results: A total of 63 materials on thyroid nodule evaluation and management were identified. A minority of materials presented readers with a complete picture of the topic, describing both benefits and cautions of thyroid nodule evaluation, benefits and cautions of fine-needle thyroid nodule biopsy, or risks, benefits, and long-term effects of thyroidectomy. The SMOG reading grade level assessment was well above recommended levels. The range was eighth grade to college level; the mean and median reading grade level were 13. Lastly, the DISCERN instrument revealed that most of the materials with both the best and the worst reading grade levels assessed had “extensive or serious shortcomings” that would impede their usefulness as high-quality sources of information regarding management options. Conclusions: Existing thyroid nodule evaluation and management materials have serious shortcomings. Future work should focus on the development of patient materials that are both grade level appropriate and meet the DISCERN criteria for topic completeness and accuracy. PMID:25384093

    Objective Physical activity improves function for adults with arthritis, but it is unknown if there is a graded relationship with functional benefit. We examine the cross-sectional and longitudinal relationship between self-reported physical activity and observed functional performance in adults with knee osteoarthritis. Methods The Osteoarthritis Initiative cohort included 2589 persons with knee osteoarthritis (2301 having longitudinal follow-up) aged 45 to 79 years at baseline. Two years of prospective annual functional performance was assessed from timed 20 meter walk tests. We used linear regression to estimate differences across physical activity quartiles in subsequent function (baseline and 1-year activity predicts 1- and 2-year function, respectively) adjusted for demographics (age, gender, race/ethnicity, education, marital status) and health factors (osteoarthritis severity, knee symptoms, knee pain, knee injury, body mass index, comorbidity, depression, smoking, alcohol use, other joint pain). Results Increasing physical activity levels had a significant graded relationship with functional performance. Adults in physical activity quartile groups, from least to most active, had average gait speed of 4.0, 4.2, 4.3, 4.5 feet/second respectively at baseline (p-value for trend <.001) and 4.1, 4.2, 4.3, 4.5 feet/second after one year (p-value for trend <.001); increasing trends remained significant after adjusting for covariates. Findings were similar within gender and age groups. Conclusion These prospective data showed a consistent graded relationship between physical activity level and better performance in adults with knee osteoarthritis. These findings support guidelines that encourage persons with arthritis who cannot attain minimum recommended physical activity to be as active as possible. PMID:20862681

    Objective The intensive nature of a 5- or 6-week teaching block poses unique problems for adequate delivery of content. This study was designed to compare the delivery of a unit of undergraduate neuroanatomy in a short summer school period, as a traditionally taught unit, with a rendition given in the form of the “Flipped Classroom.” The aim was to evaluate the effectiveness of the flipped classroom in the intensive mode classroom. Methods The flipped classroom encompassed the same learning outcomes, but students were responsible for covering the content at home in preparation for tutorials that applied their acquired knowledge to higher levels of thinking. The main outcome measures were the final course grades and the level of satisfaction with the course. Results There were no significant differences between the 2 cohorts in final grades (p = .259), self-rated knowledge (p = .182), or overall satisfaction with the course (p = .892). Conclusion This particular design of the flipped classroom did not add value to the intensive mode experience. It may be that this mode of delivery is ill suited to intensive classes for subjects that carry a lot of content. The use of the flipped classroom requires further research to fully evaluate its value. PMID:25902472

    Explanations involving submicro levels of representation are central to science education, but known to be difficult for students in secondary school. This study examines students' written explanations of physical and chemical phenomena regarding matter and changes in matter, in a large-scale test. This is done in order to understand linguistic challenges in constructing submicro level explanations involving the particle model of matter. Drawing from systemic functional linguistics, the lexicogrammatics used in explanations for realising experiential meaning in student explanations were analysed. We used answers to two partly constructed response items from the Swedish part of Trends in International Mathematics and Science Studies 2007, grade 8, to sort out explanations referring to the particle model of matter. These answers (86 from 954) were analysed regarding choices of vocabulary and grammar to distinguish between macro and submicro level of representation. The results show that students use a wide variety of lexicogrammatical resources to realise what happens on both macro and submicro level of representation, with greater diversity of verbs on the submicro level of explanation. The results suggest an uncertainty about the distinction between macro and submicro level of explanation.

  20. An instructional package integrating science and social studies instruction at the fifth-grade level

    Integrative education is being implemented by classroom teachers who want to immerse students in an environment rich in problem-solving skills, critical analysis skills, ethics, valuing of knowledge, and communication of learning. Several subject areas in the curriculum have been integrated, such as literature with social studies and mathematics with science. The focus of this dissertation is on the integration of science and social studies at the fifth grade level using the Mississippi State Department of Education Curriculum Guidelines and Objectives (MSDE, 1995) and the National Science Education Standards (National Research Council (NRC), 1996). An instructional package of lesson plans that teachers can use as ideas to create their own plans for an integrated curriculum of science and social studies was devised. The Mississippi State Department of Education Curriculum Guidelines and Objectives for Social Studies (MSDE, 1995) at the fifth grade level contain fifteen competencies. Three standards from the National Science Education Standards (NRC, 1996) were chosen. They include (a) science and technology, (b) science in personal and social perspectives, and (c) the history and nature of science. Each competency for social studies has three lesson plans written that integrate the three chosen standards from the National Science Education Standards. A total of forty-five lesson plans were written integrating science and social studies. Each lesson plan includes an objective, materials, procedures, and evaluation for teachers. Teachers are encouraged to use the lesson plans as a guide in creating their own lesson plans that would correspond to their school's particular curriculum guidelines. Consideration should be given to the learning levels and styles of their classroom. This qualitative study was done to create lesson plans that integrate science and social studies with the hope that teachers will expand upon them and implement them into their curricula.

    The canonical Wnt signaling pathway plays a major role in the regulation of embryogenesis and organogenesis, where signal strength-dependent cellular responses are of particular importance. To assess Wnt signal levels in individual cells, and to circumvent the integration site-dependent bias shown in previous Wnt reporter lines, we constructed a new Wnt signal reporter mouse line R26-WntVis. Heptameric TCF/LEF1 binding sequences were combined with a viral minimal promoter to confer a graded response to the reporter depending on Wnt signal strengths. The histone H2B-EGFP fusion protein was chosen as the fluorescent reporter to facilitate single-cell resolution analyses. This WntVis reporter gene was then inserted into the ROSA26 locus in an orientation opposite to that of the endogenous gene. The R26-WntVis allele was introduced into Wnt3a(-/-) and Wnt3a(vt/-) mutant mouse embryos and compared with wild-type embryos to assess its performance. The R26-WntVis reporter was activated in known Wnt-dependent tissues and responded in a graded fashion to signal intensity. This analysis also indicated that the major Wnt activity early in embryogenesis switched from Wnt3 to Wnt3a around E7.5. The R26-WntVis mouse line will be widely useful for the study of Wnt signal-dependent processes. PMID:27030109

    Mountain endurance running has increased in popularity in recent years. Thus the aim of the present study was to determine if maximal oxygen uptake (VO2max) and energy cost of running (Cr) measured during level and uphill running are associated. Ten high level male endurance mountain runners performed three maximal oxygen uptake tests at three slope conditions (0, 12.5 and 25%). Metabolic data, step frequency (SF) and step length (SL) were recorded. No significant differences were found in VO2max (63.29 (±3.84), 63.97 (±3.54) and 63.70 (±3.58) mlO2/kg-1/min-1) or associated metabolic data at 0, 12.5 and 25% slope respectively. High intra-individual correlations were found between metabolic data measured in the three conditions. The energy cost of running was significantly different between slopes (0.192 (±0.01), 0.350 (±0.029) and 0.516 (±0.035) mlO2/kg-1/min-1, p < 0.01), 0, 12.5 and 25% respectively. However, Cr0% was not correlated with either Cr25% or Cr12.5% (rs = 0.09 and rs = 0.10), in contrast, Cr25% and Cr12.5% were correlated (rs = 0.78). Step length was positively correlated with speed under the three slope conditions. Step frequency was significantly lower at 25 compared to 12.5 and 0% slope. We found that the maximum aerobic power did not differ between level and graded treadmill tests. However, the increase in Cr on the inclined versus level conditions varied between subjects. None of the measured anthropometric or kinematic variables could explain the higher increase in Cr of some subjects when running uphill. Thus, a short graded (5min at 12.5%) running test should be performed at a submaximal velocity (around 40% of level vVO2max) to enhance understanding of an endurance runner’s uphill capability. Key points In elite endurance mountain runners, there is no difference in VO2max values between level and uphill running. In a homogeneous group of mountain runners, uphill Cr is not associated with level Cr. To assess performance potential of

    This paper explored variation of student numerical and figural reasoning approaches across different pattern generalization types and across grade level. An instrument was designed for this purpose. The instrument was given to a sample of 1232 students from grades 4 to 11 from five schools in Lebanon. Analysis of data showed that the numerical reasoning approach seems to be more dominant than the figural reasoning approach for the near and far pattern generalization types but not for the immediate generalization type. The findings showed that for the recursive strategy, the numerical reasoning approach seems to be more dominant than the figural reasoning approach for each of the three pattern generalization types. However, the figural reasoning approach seems to be more dominant than the numerical reasoning approach for the functional strategy, for each generalization type. The findings also showed that the numerical reasoning was more dominant than the figural reasoning in lower grade levels (grades 4 and 5) for each generalization type. In contrast, the figural reasoning became more dominant than the numerical reasoning in the upper grade levels (grades 10 and 11).

    The aim of this study was to investigate the effects of graded levels of montmorillonite, a constituent of clay, on performance, hematological parameters and bone mineralization in weaned pigs. One hundred and twenty, 35-d-old crossbred pigs (Duroc×Large White×Landrace, 10.50±1.20 kg) were used in a 28-d experiment and fed either an unsupplemented corn-soybean meal basal diet or similar diets supplemented with 0.5, 1.0, 2.5 or 5.0% montmorillonite added at the expense of wheat bran. Each treatment was replicated six times with four pigs (two barrows and two gilts) per replicate. Feed intake declined (linear and quadratic effect, p< 0.01) with increasing level of montmorillonite while feed conversion was improved (linear and quadratic effect, p<0.01). Daily gain was unaffected by dietary treatment. Plasma myeloperoxidase declined linearly (p = 0.03) with increasing dietary level of montmorillonite. Plasma malondialdehyde and nitric oxide levels were quadratically affected (p<0.01) by montmorillonite with increases observed for pigs fed the 0.5 and 1.0% levels which then declined for pigs fed the 2.5 and 5.0% treatments. In bone, the content of potassium, sodium, copper, iron, manganese and magnesium were decreased (linear and quadratic effect, p<0.01) in response to an increase of dietary montmorillonite. These results suggest that dietary inclusion of montmorillonite at levels as high as 5.0% does not result in overt toxicity but could induce potential oxidative damage and reduce bone mineralization in pigs.

    Food intake and circadian rhythms are regulated by hypothalamic neuropeptides and circulating hormones, which could mediate the anti‐ageing effect of calorie restriction (CR). We tested whether these two signaling pathways mediate CR by quantifying hypothalamic transcripts of male C57BL/6 mice exposed to graded levels of CR (10 % to 40 %) for 3 months. We found that the graded CR manipulation resulted in upregulation of core circadian rhythm genes, which correlated negatively with circulating levels of leptin, insulin‐like growth factor 1 (IGF‐1), insulin, and tumor necrosis factor alpha (TNF‐α). In addition, key components in the hunger signaling pathway were expressed in a manner reflecting elevated hunger at greater levels of restriction, and which also correlated negatively with circulating levels of insulin, TNF‐α, leptin and IGF‐1. Lastly, phenotypes, such as food anticipatory activity and body temperature, were associated with expression levels of both hunger genes and core clock genes. Our results suggest modulation of the hunger and circadian signaling pathways in response to altered levels of circulating hormones, that are themselves downstream of morphological changes resulting from CR treatment, may be important elements in the response to CR, driving some of the key phenotypic outcomes.

    The effects of graded atmospheric O2 concentration (12, 14, 16, 18, and 20.6%) on chick performance and propensity to develop ascites were investigated using commercial male broilers. Chicks were housed in calorimetry chambers for 2 wk with incoming air diluted with N to provide the desired O2 concentration at thermoneutral (TN) ambient temperature. Day 14 body weight, weight gain, feed consumption, and gain-to-feed ratio increased (P < 0.01) as O2 concentration incrementally rose from 12 to 20.6%. Body weight was 138 g for the lowest atmospheric O2 level compared to 371 g for 20.6% O2. The greatest treatment difference occurred between the 12 and 14% O2 concentrations. Growth depression appeared related to feed consumption. Ascites heart ratio (AHR), ascites score (AS), right ventricular mass (RVM), and hematocrit (HCT) all increased (P < 0.01) as O2 concentration decreased. Blood HCT appeared to be a more sensitive indicator of physiological change attributable to atmospheric O2 than AHR, AS, or RVM. The data reported herein suggests that 19.6% atmospheric O2 is the minimal allowable level for housing birds within a relatively stress-free, TN environment to avoid cardiac and HCT changes related to ascites.

  19. Elevated Serum MicroRNA Levels Associate with Absence of High-Grade Prostate Cancer in a Retrospective Cohort

    2015-01-01

    To reduce treatment of indolent prostate cancer (PCa), biomarkers are needed to improve identification of patients with a low-risk of having aggressive disease. Over-treatment of these patients occurs because of uncertainty in the aggressiveness of the entire tumor based on the biopsies, which do not accurately sample multifocal tumors. Circulating microRNAs (miRNAs) are stable serum markers and differential miRNA levels occur in men with PCa. The goal of this study was to identify circulating miRNAs that were associated with aggressive or indolent PCa. We measured circulating miRNAs in 150 patients prior to surgery and compared the miRNA levels to the pathology of the entire radical prostatectomy specimen. For this study we used an exceptionally well-characterized cohort of patients who had benign prostatic hyperplasia (BPH), low-grade or high-grade PCa. Low-grade was defined as patients with 100% Gleason grade 3 tumor as determined by step-wise sectioning. High-grade PCa patients had 30-90% Gleason grade 4+5 in the tumor. BPH patients had at least two biopsies negative for PCa. Twenty one miRNAs were selected for analysis. The miRNAs were quantified by RT-qPCR and analyzed by logistic regression. High levels of 14 miRNAs were exclusively present in the serum from patients with low-grade PCa or BPH, compared to men with high-grade PCa who had consistently low levels. The expression levels of the 14 miRNAs were combined into a “miR Score” which had a negative predictive value (NPV) of 0.939 to predict absence of high-grade PCa among PCa and BPH patients. Biochemical recurrence (BCR) was known for the PCa patients and a combined “miR Risk Score” accurately classified a subset of patients with low risk of BCR (NPV 0.941). In summary, measurement of serum miRNAs may have pre-surgical utility in combination with clinical risk calculators to identify patients with low risk of harboring aggressive PCa. PMID:25874774

  20. Oxidation resistance of 9-12% Cr steels: effect of rare earth surface treatment

    2005-02-01

    Medium Cr steels have been used in fossil fired power plants for many years because of their excellent high temperature stability and mechanical properties. The environment in a fossil fired power plant is extremely aggressive in terms of corrosion, especially oxidation. This is only accelerated as the operating temperature increases to 650C and beyond. For any new steel to be qualified for power plant use, in addition to adequate strength at the operating temperature, material wastage from all corrosion processes must be kept to a minimum acceptable level. The use of medium Cr steels provides a means to improve overall corrosion resistance. Three medium Cr are under development for use as high temperature power plant steels: 0.08C-(9-12)Cr-1.2Ni-0.7Mo-3.0Cu-3.0Co-0.5Ti. Oxidation tests were performed on the steels for times greater than 1000 hours in order to determine the oxidation kinetics and extent of material wastage. Also, rare earth oxides were incorporated into the outer surface layers of the steels to see if the oxidation resistance could be improved. These results will be compared to current power plant steels.

  2. Nadir CA-125 level as prognosis indicator of high-grade serous ovarian cancer

    2013-01-01

    Purpose The capacity of nadir CA-125 levels to predict the prognosis of epithelial ovarian cancer remains controversial. This study aimed to explore whether the nadir CA-125 serum levels could predict the durations of overall survival (OS) and progression free survival (PFS) in patients with high-grade serous ovarian cancer (HG-SOC) from the USA and PRC. Materials and methods A total of 616 HG-SOC patients from the MD Anderson Cancer Center (MDACC, USA) between 1990 and 2011 were retrospectively analyzed. The results of 262 cases from the Jiangsu Institute of Cancer Research (JICR, PRC) between 1992 and 2011 were used to validate the MDACC data. The CA-125 immunohistochemistry assay was performed on 280 tissue specimens. The Cox proportional hazards model and the log-rank test were used to assess the associations between the clinicopathological characteristics and duration of survival. Results The nadir CA-125 level was an independent predictor of OS and PFS (p < 0.01 for both) in the MDACC patients. Lower nadir CA-125 levels (≤10 U/mL) were associated with longer OS and PFS (median: 61.2 and 16.8 months with 95% CI: 52.0–72.4 and 14.0–19.6 months, respectively) than their counterparts with shorter OS and PFS (median: 49.2 and 10.5 months with 95% CI: 41.7–56.7 and 6.9–14.1 months, respectively). The nadir CA-125 levels in JICR patients were similarly independent when predicting the OS and PFS (p < 0.01 for both). Nadir CA-125 levels less than or equal to 10 U/mL were associated with longer OS and PFS (median: 59.9 and 15.5 months with 95% CI: 49.7–70.1 and 10.6–20.4 months, respectively), as compared with those more than 10 U/mL (median: 42.0 and 9.0 months with 95% CI: 34.4–49.7 and 6.6–11.2 months, respectively). Baseline serum CA-125 levels, but not the CA-125 expression in tissues, were associated with the OS and PFS of HG-SOC patients in the MDACC and JICR groups. However, these values were not independent. Nadir CA-125

  3. Using GRADE to respond to health questions with different levels of urgency.

    PubMed

    Thayer, Kristina A; Schünemann, Holger J

    2016-01-01

    Increasing interest exists in applying the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to environmental health evidence. While ideally applied to evidence synthesized in systematic reviews and corresponding summary tables, such as evidence profiles, GRADE's correct application requires that "the evidence that was assessed and the methods that were used to identify and appraise that evidence should be clearly described." In this article, we suggest that GRADE could be applied to evidence assembled from narrative reviews, modelled (indirect) evidence, or evidence assembled as part of a rapid response, if the underlying judgments about the certainty in this evidence are based on the relevant GRADE domains and provided transparently. Health questions that require assessing the certainty in a body of evidence to provide trustworthy answers may range from hours, to days or weeks, to a few months to scenarios that allow assessing evidence without short-term time pressures. Time frames of emergent, urgent or rapid evidence assessments will often require relying on existing summaries or rapidly compiling the available evidence and making assessments. Even without available full systematic reviews, expressing the certainty in the evidence can provide useful guidance for users of the evidence and those who evaluate certainty in effects. The ratings also help clarifying disagreement between organizations tackling similar questions about the evidence. Using the structured GRADE domains, narrative or other summaries of the evidence can be presented transparently. PMID:27126781

    1999-01-01

    The objective of this study was to determine the acute gastrointestinal effects caused by the consumption of drinking water containing graded levels of added copper. Sixty healthy, adult women were randomly assigned to receive copper [Cu(II)] at four concentrations in their drinking water following a Latin-square design. Each group (n = 15) received tap water with no added copper, 1, 3, and 5 mg Cu/l of added copper sulfate for a 2-week study period, followed by 1 week of standard tap water. The subjects recorded their water consumption and gastrointestinal symptoms daily on a special form. The average daily consumption of water was 1.64 liters per subject, regardless of the amount of copper added. Final serum copper, ceruloplasmin, and liver enzymes were measured in all subjects and were not different from baseline concentrations. Twenty-one subjects (35%) recorded gastrointestinal disturbances sometime during the study, 9 had diarrhea, some with abdominal pain and vomiting, and 12 subjects presented abdominal pain, nausea, or vomiting. There was no association between copper levels in drinking water and diarrhea. However, nausea, abdominal pain, or vomiting were significantly related to copper concentrations in water. The recorded incidence rate of these symptoms was 5, 2, 17, and 15% while ingesting water with 0, 1, 3, and 5 mg Cu/l, respectively (overall [chi]2 = 11.3, p<0.01; Cu [less than/equal to]1 mg/l versus Cu [Greater than/equal to]3 mg/l, [chi]2, p<0.01). When subjects interrupted their consumption of drinking water with added copper, most symptoms disappeared. We conclude that under the conditions of the study, there was no association between aggregate copper in drinking water within the range of 0-5 mg/l and diarrhea, but a [Greater than/equal to]3 mg Cu/l level of ionized copper was associated with nausea, abdominal pain, or vomiting. Additional studies with sufficient numbers of subjects are needed to define thresholds for specific gastrointestinal

    2014-01-01

    This study was conducted for 10 weeks with the aim of investigating the erythrocyte membrane integrity as measured by erythrocyte osmotic fragility and excitability scores of rabbits fed graded level of Hibiscus sabdariffa calyx (HSC). Twenty weaners' rabbit of both sexes were used for the study and were placed on four experimental diets which contain the following percentages of HSC 0 %, 25 %, 50 %, 75 %, as feed additive and were added at 0 g, 62.5 g, 125 g, 187.5 g designated as T1, T2, T3 and T4 experimental diets. Excitability scores were measured weekly as described by Voisnet et al. (1997). At the end of the experiment, the rabbits were slaughtered by severing the jugular vein. A Blood sample (2 ml) was collected from each rabbit into sampled bottles, containing the Na EDTA as anticoagulant for hematological analysis. Packed cell volume (PCV) Haemoglobin concentration (Hb), Total red blood cell (RBC) count, Total leukocyte count as well as differential leukocyte was determined using standard method. The percentage haemolysis recorded at 0.3 % to 0.8 % was significantly (P < 0.05) higher in rabbits in T1 compared to the remaining 3 diets. The result of excitability score shows that rabbit on diet 1 and 2 had a lower value which was significantly (P < 0.05) lower than rabbits on diets 3 and 4 with a value of 65.5 ± 5.0 and 70.00 ± 5.50 % respectively. In conclusion this study demonstrated for the first time that chronic administration of HSC improves haematological parameters, brain mood and function as well as maintaining erythrocyte membrane integrity.

    Overexpression of human epidermal growth factor receptor 2 (HER2) is an important prognostic and predictive marker of response to anti-HER2 therapy in breast cancer. Our goal was to analyze the prognostic significance of moderate expression of HER2 in breast cancer with intermediate differentiation grade. We performed a multicenter retrospective register study of 8494 patients with primary non-metastatic breast cancer admitted between 2000 and 2011 to eight Clinics in Saxony-Anhalt, federal state of Germany. Patients were divided into three groups according to their HER2 score: 4073 were classified as HER2 negative (HER2 0 and 1+), 822 HER2 moderate (HER2 2+/HER2), and 1238 HER2 positive (HER2 3+ or HER2 2+/HER2+). HER2-positive cases were excluded from analysis. Tumors with moderate HER2 (HER2 2+) expression demonstrated an aggressive behavior and worse patient survival compared with HER2 0 and 1+ status. HER2 2+ status was associated with shorter median overall survival (OS) (P < 0.0001) in breast cancer patients with an intermediate grade of differentiation. Comparing low-grade and high-grade tumors, HER2 moderate expression did not significantly influence patient survival. In multivariate analysis after adjustment for other prognostic factors HER2 2+ status remained an unfavorable prognostic factor for OS (HR 1.224, 95 % CI 1.059-1.415, P = 0.006) in breast cancer patients with an intermediate grade of differentiation. HER2 2+ status is an unfavorable prognostic factor regarding the OS of breast cancer patients with intermediate grade of differentiation and could be used to identify patients, who may benefit from adjuvant therapy.

  9. School-based exposure to hazardous air pollutants and grade point average: A multi-level study.

    2016-05-01

    The problem of environmental health hazards around schools is serious but it has been neglected by researchers and analysts. This is concerning because children are highly susceptible to the effects of chemical hazards. Some ecological studies have demonstrated that higher school-level pollution is associated with lower aggregate school-level standardized test scores likely, related to increased respiratory illnesses and/or impaired cognitive development. However, an important question remains unexamined: How do school-level exposures impact individual children's academic performance? To address this, we obtained socio-demographic and grades data from the parents of 1888 fourth and fifth grade children in the El Paso (Texas, USA) Independent School District in 2012. El Paso is located on the US-side of the Mexican border and has a majority Mexican-origin population. School-based hazardous air pollution (HAP) exposure was calculated using census block-level US Environmental Protection Agency National Air Toxics Assessment risk estimates for respiratory and diesel particulate matter (PM). School-level demographics were obtained from the school district. Multi-level models adjusting for individual-level covariates (e.g., age, sex, race/ethnicity, English proficiency, and economic deprivation) and school-level covariates (e.g., percent of students economically disadvantaged and student-teacher ratio) showed that higher school-level HAPs were associated with lower individual-level grade point averages. An interquartile range increase in school-level HAP exposure was associated with an adjusted 0.11-0.40 point decrease in individual students' grade point averages (GPAs), depending on HAP type and emission source. Respiratory risk from HAPs had a larger effect on GPA than did diesel PM risk. Non-road mobile and total respiratory risk had the largest effects on children's GPA of all HAP variables studied and only mother's level of education had a larger effect than those

    2016-05-01

    The impact of graded levels of day-length on the productivity of hens and toms was studied in two trials. Daylength treatments (trts) were 14 (14L), 17 (17L), 20 (20L), and 23 (23L) h and were started at 10 d of age. Turkeys (720 hens and 480 toms) were randomly allocated to 8 rooms (2 rooms per lighting trt) with six pens (3 hen--30 per pen and 3 tom--20 per pen) per room in each trial. Body weight (BW) was assessed at 0, 10, 21, 42, 63, 84, and 126 d of age; feed consumption (FC) was measured for the time periods between body weight determinations and feed efficiency (G:F; g of gain/g of feed) was calculated from BW and FC values. Birds were checked daily for mortality and culls, and affected birds were sent for necropsy. Data were analyzed according to a completely randomized block design with trial as the block and rooms nested within lighting trts. Regression analysis was used to study the relationship between dependent variables and daylength. Significance was declared at P≤ 0.05 and trends at P≤ 0.10. At both 21 and 42 d, body weight increased linearly with increasing daylength. At 84 d weights of toms decreased in a quadratic fashion and hen weights were unaffected. At 126 d, both tom and hen weights decreased linearly as daylength increased, with the magnitude of response gender dependent. Feed consumption corresponded with body weight changes, increasing for d 10 to 21, and 21 to 42 and decreasing for d 63 to 84, 84 to 105, and 105 to 126 with increasing daylength. Feed efficiency (G:F) was not affected by daylength for 10 to 84, 10 to 105 and 10 to 126 d periods. The incidence of mortality and culling was not affected by daylength for the 10 to 84 d period, but increased in a quadratic manner with increasing daylength for the 10 to 105 and 10 to 126 d periods. To conclude, daylength affects the growth and feed intake of turkeys in an age and gender-specific manner, and mortality and culling increase with longer daylength. PMID:26976908

  15. Room and elevated temperature Mechanical Behavior of 9-12% Cr Steels

    SciTech Connect

    Dogan, Omer N.; Hawk, Jeffrey A.; Schrems, Karol K.

    2005-02-01

    The mechanical properties of medium Cr steels used in fossil fired power plants are very good because of their excellent high temperature microstructural stability. However, as the desire to increase the operating temperature (>650C) of the plant goes up, the need for steels that maintain their strength at these temperatures also increases. The mechanical properties of three medium Cr steels (0.08C-(9-12)Cr-1.2Ni-0.7Mo-3.0Cu-3.0Co-0.5Ti) were investigated through hardness, hot hardness and tensile measurements. The strength of the 9-12%Cr steels at room temperature after long-term isothermal aging (750C; 1000 hours) compares favorably with that of other power plant steels (e.g., P91). In addition, the elevated temperature strength and hot hardness also behave similarly. The mechanical behavior will be discussed in terms of the strength, elongation and tensile fracture characteristics.

  10. Growth, haematology, blood constituents and immunological status of lambs fed graded levels of animal feed grade damaged wheat as substitute of maize.

    PubMed

    Tripathi, M K; Mondal, D; Karim, S A

    2008-02-01

    The aim of this study was to explore possibilities of utilization of animal feed grade damaged wheat (ADW) in lamb feeding, and assess the effect of ADW and its aflatoxin on intake, growth, haematology, blood biochemical constituents and immunological status. The ADW is a slightly mouldy feed resource, which is not suitable for human consumption. The experimental ADW contained dry matter (DM) 964, organic matter 974, crude protein 153, cellulose 205 and lignin 24, and starch 732 g/kg DM. ADW also contained aflatoxin B1 50 microg/kg due to mould infestation. Thirty-five weaner lambs (90 +/- 15 days of age and 16.1 +/- 0.82 kg body weight) in a randomized design were fed for 91 days on one of four composite feed mixtures (roughage to concentrate ratio of 25:75) containing 0, 118, 235, 353 or 470 g/kg ADW, which replaced equal amounts of maize and at these inclusion levels ADW replaced 0%, 25%, 50%, 75% and 100% maize in lamb diets respectively. Dry matter intake (DMI) was similar in different level of ADW fed lambs but ADW inclusion linearly (p = 0.016) reduced DMI. Average daily gain (g/day) was higher (p = 0.038) in lambs fed 353 g ADW diet. Haematological attributes viz. WBC, haemoglobin (Hb) and mean corpuscular volume did not affect by ADW feeding whereas it increased haematocrit, mean cell Hb and decreased neutrophil, RBC counts and mean cell Hb concentration. Blood glucose and urea-N increased whereas albumin and protein level reduced by ADW feeding. ADW feeding of lambs did not affect serum IgG level. The activities of serum aspartate aminotransferase, alkaline phosphates and acid phosphates were not affected, whereas alanine aminotransferase increased linearly (p = 0.001) with increasing levels of ADW. It is concluded that ADW containing aflatoxin B1 50 microg/kg DM can safely be incorporated in growing lamb feeding up to 353 g/kg diet without affecting growth and cellular immunity, however ADW may induce a transient alteration of hepatic enzymatic

  11. Content, format, gender and grade level differences in elementary students' ability to read science materials as measured by the cloze procedure

    NASA Astrophysics Data System (ADS)

    Williams, Richard L.; Yore, Larry D.

    Present instructional trends in science indicate a need to reexamine a traditional concern in science education: the readability of science textbooks. An area of reading research not well documented is the effect of color, visuals, and page layout on readability of science materials. Using the cloze readability method, the present study explored the relationships between page format, grade level, sex, content, and elementary school students ability to read science material. Significant relationships were found between cloze scores and both grade level and content, and there was a significant interaction effect between grade and sex in favor of older males. No significant relationships could be attributed to page format and sex. In the area of science content, biological materials were most difficult in terms of readability followed by earth science and physical science. Grade level data indicated that grade five materials were more difficult for that level than either grade four or grade six materials were for students at each respective level. In eight of nine cases, the science text materials would be classified at or near the frustration level of readability. The implications for textbook writers and publishers are that science reading materials need to be produced with greater attention to readability and known design principles regarding visual supplements. The implication for teachers is that students need direct instruction in using visual materials to increase their learning from text material. Present visual materials appear to neither help nor hinder the student to gain information from text material.

  12. Interpreting GRADE's levels of certainty or quality of the evidence: GRADE for statisticians, considering review information size or less emphasis on imprecision?

    PubMed

    Schünemann, Holger J

    2016-07-01

    This article responds to issues raised by Antilla et al. in the Journal of Clinical Epidemiology about the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Working Group's approach to rating imprecision and GRADE's use of statistics. They argue that GRADE confuses statistical terms and should provide a stepwise rating of imprecision for making decisions. Here, a clarification of those perceptions is provided. GRADE's ratings of imprecision and other quality of evidence domains is an iterative process that may or may not consider people important thresholds of effects when systematic review authors rate imprecision. Regardless of ratings in systematic reviews, those suggesting decisions such as guideline panels, should consider if they agree or need to revise these suggested thresholds to make informed ratings about imprecision. Decision relevant thresholds are the result of a complex interplay between critical outcomes for a decision-making. The certainty in the evidence of one critical outcome and the resulting possible certainty range, which I conceptualize in this article, may influence ratings of other outcomes. To relieve systematic review authors of the often challenging burden of defining worthwhile or important effects for judging precision based on the optimal information size (OIS), a modified OIS or review information size (RIS) could be used to rate imprecision at the systematic review stage. The RIS focuses only on plausible rather plausible and worthwhile effects. The advantages of using the RIS include avoiding the reliance on statistical significance alone and the varying thresholds resulting from the importance and the baseline risk of the outcome on which the OIS relies. Finally, I argue that GRADE's certainty in the evidence is related to the statistical definition of accuracy but given GRADE's broad application to other ratings of certainty such as qualitative evidence, statistical accuracy does not serve as a definition

    Neutron fluence measurements and radiation damage calculations are reported for the joint US-Japanese experiments JP-9, -12, and -15. These experiments were conducted in target positions of the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory (ORNL) for a period of nearly four years. The maximum neutron fluence at midplane was 2.6 {times} 10{sup 23} n/cm{sup 2} (7.1 {times} 10{sup 22} n/cm{sup 2} above 0.1 MeV), resulting in about 60 dpa and 3900 appm helium in type 316 stainless steel.

    High-chromium heat-resistant steel has been widely used as the key material to improve the condition of steam pressure and temperature in the modern high-efficiency power plants. Despite the use of the steel above 550°C for several decades, its major failure is owing to the creep fracture. In this study, the effect of creep stress on the microstructure in 9-12% Cr steel has been investigated microscopically, and it is clarified that the creep stress enhances precipitation of Laves phase and influences the lath width and dislocation density in lath interior.

    Differences were examined in Theory of Planned Behaviour determinants of students' intention to smoke including parents' attitudes towards smoking and parents' current cigarette use among Greek students of different school grade levels. Students (N = 763) aged 10-18 years reported their attitudes towards smoking, subjective norms, perceived behavioural control, self-identity and intention to smoke while their parents (N = 525) reported their attitudes towards smoking and their current cigarette use. All the TPB variables increased from lower to higher school grade level. Multi-sample path analyses showed that parent's attitudes towards smoking positively predicted students' intention to smoke only for elementary school children. Parents' current cigarette use did not contribute significantly. Students' attitudes, perceived behavioural control and self-identity predicted systematically intention to smoke in contrast to the subjective norm that did not contribute at all. Perceived behavioural control contributed to a higher degree in intention to smoke for senior high school students compared to the junior high school and elementary students. Self-identity contributed to a higher degree in intention to smoke for elementary compared to the junior high school students. The results of this study suggests that the determinants of smoking vary between early and late adolescence. PMID:21834644

    The objective of the study was to determine effect of feeding fibrous diets on performance and biochemical profiles of finishing pigs. A total of 84 clinically healthy male pigs were used in the experiment. Body weight of the pigs at the beginning of the experiment was 85 ± 10.1 kg. Maize cob (MC), sunflower hulls (SH), lucerne hay (LH) and dried citrus pulp (PU) were incorporated in a basal diet for finishing pigs at different inclusion levels of 0, 80, 160, 240, 320 and 400 g/kg. Effects of week of feeding, fibre source and inclusion level of fibre were significant (P < 0.05). Pigs consumed more LH compared to MC, SH and PU. Average daily gain was high for pigs consuming diets with inclusion levels of 0, 80, 160 and 240 g/kg and low for pigs consuming 320 and 400 g/kg inclusion level of fibre in a diet. There was an increase in serum total concentration (TP) with an increase in PU, MC and LH in pig diets (P < 0.05). Creatine kinase (CK) concentrations decreased as levels of PU, LH and MC increased (P < 0.05). Increasing inclusion level of LH and SH in pig diets resulted in an increase in glycated haemoglobin concentration (P < 0.05). It can be concluded that level of PU, LH, MC and SH in diets of finishing pigs negatively influences average daily feed intake, average daily gain and biochemical profiles. PMID:26984596

    Various martensitic 9-12 Cr steels are utilized currently in fossil fuel powered energy plants for their good elevated temperature properties such as creep strength, steam side oxidation resistance, fire side corrosion resistance, and thermal fatigue resistance. Need for further improvements on the properties of 9-12 Cr steels for higher temperature (>600oC) use is driven by the environmental concerns (i.e., improve efficiency to reduce emissions and fossil fuel consumption). In this paper, we will discuss the results of the research done to explore new subsitutional solute solution and precipitate hardening mechanisms for improved strength of 9-12 Cr martensitic steels. Stability of the phases present in the steels will be evaluated for various temperature and time exposures. A comparison of microstructural properties of the experimental steels and commercial steels will also be presented.

    The influence of a Ce surface treatment on oxidation behavior of a commercial (P91) and several experimental steels containing 9 to 12 weight percent Cr was examined at 650ºC in flowing dry and moist air. The oxidation behavior of all the alloys without the Ce modification was significantly degraded by the presence of moisture in the air during testing. For instance the weight gain for P91 was two orders of magnitude greater in moist air than in dry air. This was accompanied by a change in oxide scale from the formation of Cr-based scales in dry air to the formation of Fe-based scales in moist air. The Ce surface treatment was very effective in improving the oxidation resistance of the experimental steels in both moist and dry air. For instance, after exposure to moist air at 650ºC for 2000 hours, an experimental alloy with the cerium surface modification had a weight gain three orders of magnitude lower than the alloy without the Ce modification and two orders of magnitude lower than P91. The Ce surface treatment suppressed the formation of Fe-based scales and

    Alpha-lactose monohydrate is widely used as an excipient in dry powder inhalers, and plays a very important role in the efficiency of the drug delivery. Due to the processing, low levels of amorphous lactose could be present in the blends. Varying amounts could have a strong effect on the efficiency of drug delivery of the powder blends. Therefore, the accurate measurement of low levels of amorphous lactose content is very important. A new method was developed to measure the amorphous content, based on dynamic vapour sorption (DVS). In contrast to the traditional re-crystallization approach of amorphous lactose, the new method is based on moisture sorption isotherms. Moisture sorption isotherms of blends of crystalline alpha-lactose and freeze-dried or spray-dried amorphous lactose were measured. By fitting the data with a Brunauer, Emmett, and Teller (BET) isotherm, a linear correlation was found between measured and actual amorphous content for the whole range of 0.1-100%. Differences between freeze-dried and spray-dried lactose, due to different molecular arrangements, could be removed by a preconditioning the samples at 35% RH prior to the isotherm measurement. It was shown that accurate determination of very low concentrations of amorphous lactose content is possible using moisture sorption isotherm analyses. PMID:20493937

  8. The optimum level of parent participation: A study of three intensity levels of parent involvement during three "Playtime is Science" units in three third-grade classes

    The study describes the experience of introducing three intensity levels of parent participation in three third-grade classes for science instruction using Playtime is Science; an equity curriculum that utilizes parent participation. The study sought to determine the optimum level of participation by ascertaining the most influential aspect of involvement on proficiency scores and the most important aspect of involvement to participants. The levels of participation intensity were distinguished by: (1) the number of parents in the classroom; (2) the responsibilities of the parents; (3) the training received; and (4) the number of students with whom the parents worked. Involvement at each level would potentially manifest aspects of role modeling, lowered student-to-adult instructional ratio, and parent expertise to varying degrees. The three levels of participation were introduced during explorations in three Playtime is Science units following a rotation schedule. Student proficiency was assessed through scores on pre- and post-tests, journals, and discourse. ANCOVA was used to identify main and interaction effects of the independent variables (class, unit and level) on student proficiency taking into account existing differences in groups. Participant attitudes were assessed through journals and interviews. Observations of explorations triangulated findings and assessed participant interactions. Field notes, transcripts and photographs were coded according to the aspects of parent involvement. The results showed level of parent intensity of involvement had no affect on proficiency scores. Therefore, no aspect of parent involvement was determined to be the most influential. Participants felt that lowered instructional ratio and role modeling were the most important aspects of involvement. The level of involvement that utilized the lowest ratio and the most role modeling was level III, small group facilitators. Level III was recognized as the optimum level of

    Extracts of sex pheromone glands obtained from females ofPloida interpunctella contained detectable amounts of (Z,E,)-9,12-tetradecadien-1-ol acetate (Z9,E12-14:Ac) and (Z,E.)-9,12-tetradecadien-1-ol (Z9,E12-14:OH) 4 hr prior to the first scotophase after adult emergence. The amount of pheromone increased during the first 4 hr of the scotophase and then declined to low levels during the subsequent photophase. Decapitation of females immediately after emergence, prior to expansion of the wings, inhibited production of pheromone during the subsequent 48 hr. Injection of extracts of the heads of 1-day-old females ofP. interpunctella of partially purified extracts of the cephalic ganglia of females of the corn earworm moth into decapitated females stimulated production of bothZ9,E12-14:Ac andZ9,E12-14:OH as well as production of (Z,E)-9,12-tetradecadienal (Z9,E12-14:Al). This aldehyde was subsequently identified from extracts of pheromone glands obtained from naturally calling females as well as from volatiles emitted by calling females. Studies on the terminal steps in biosynthesis of the pheromone showed thatZ9,E12-14:OH was produced from the corresponding acetate and thatZ9,E12-14:Al was produced from the alcohol via the action of an oxidase(s).

    1977-01-01

    Three nitrogen metabolism experiments were conducted to determine the qualitative and quantitative histidine need of first-litter gilts during the last third of pregnancy. A completely purified, crystalline 8amino acid diet was formulated to meet all nutrient needs of the gravid gilt when 2 kg/day was fed. Experiments 1 and 2 were 9-day nitrogen balance studies, each consisting of three littermate gilts subjected to three levels of dietary L-histidine in a Latin square arrangement of treatments. Nitrogen retention was depresed, but not significantly, when less than 0.12% histidine was fed. Complete deletion of histidine, however, did not depress retention below that observed when 0.06% was fed. This suggested that either histidine biosynthesis or its release from endogenous reserves was confounding retention data. Therefore in a third experiment, two gilts were fed a histidine-free diet for 24 days in an attempt to deplete endogenous reserves. For comparison, two siblings were fed 0.12% histidine during this same period. Nitrogen retention tended to be lower for gilts fed the histidine-free diet during each of three consecutive collection periods. Blood hemoglobin, muscle and olfactory bulb carnosine concentration, plasma protein and glutamic-oxaloacetic transaminase activity, and blood urea nitrogen were all unaffected by treatment. Offspring from gilts fed the histidine-free diet had lower blood hemoglobin concentrations than their counterparts from gilts receiving histidine. A tentative recommendation of 0.12% dietary L-histidine would seem justified for gravid swine. PMID:833672

    Arsenic exposure in children is a public health concern but is understudied in relation to the predictors, and effects of low-level exposure. We examined the extent and dietary predictors of exposure to inorganic arsenic in 5-8 year old children from Montevideo, Uruguay. Children were recruited at school; 357 were enrolled, 328 collected morning urine samples, and 317 had two 24-h dietary recalls. Urinary arsenic metabolites, i.e. inorganic arsenic (iAs), methylarsonic acid (MMA), and dimethylarsinic acid (DMA), were measured using high-performance liquid chromatography with hydride generation and inductively coupled plasma mass spectrometry (HPLC-HG-ICP-MS), and the sum concentration (U-As) used for exposure assessment. Proportions of arsenic metabolites (%iAs, %MMA and %DMA) in urine were modelled in OLS regressions as functions of food groups, dietary patterns, nutrient intake, and nutritional status. Exposure to arsenic was low (median U-As: 9.9µg/L) and household water (water As: median 0.45µg/L) was not a major contributor to exposure. Children with higher consumption of rice had higher U-As but lower %iAs, %MMA, and higher %DMA. Children with higher meat consumption had lower %iAs and higher %DMA. Higher scores on "nutrient dense" dietary pattern were related to lower %iAs and %MMA, and higher %DMA. Higher intake of dietary folate was associated with lower %MMA and higher %DMA. Overweight children had lower %MMA and higher %DMA than normal-weight children. In summary, rice was an important predictor of exposure to inorganic arsenic and DMA. Higher meat and folate consumption, diet rich in green leafy and red-orange vegetables and eggs, and higher BMI contributed to higher arsenic methylation capacity. PMID:26828624

    The purposes of this study were to identify the attitudes and beliefs content teachers have concerning teaching reading in the content area to below level readers and to identify specific instructional strategies that are used to teach students who are below grade level the content area material. Twelve participants were selected, using maximum variation sampling, based on the grade level and content area they taught. Data was collected from middle school content area teachers using interviews, surveys, observations, and document examination in an attempt to identify attitudes, beliefs, and specific challenges content teachers face instructing below grade level readers. The data was collected, coded and analyzed for specific commonalities. The constructivist's theory served as the framework for the study with emphasis on experiential learning. The experiences that the participants had as early learners, older students, and adult teachers mold their level of efficacy, the way they teach, and the way the view teaching and learning. Based on the data collected and analyzed, common attitudes and beliefs were present among the participants. Common instructional strategies used with below level learners were also identified. The challenges content area teachers face were also recognized. Recommendations were made to school districts, teacher prep programs administrators and to others for further research.

    Glial tumours are a devastating, poorly understood condition carrying a gloomy prognosis for which clinicians sorely lack reliable predictive parameters facilitating a sound treatment strategy. Tp73, a p53 family member, expresses two main classes of isoforms--transactivatory activity (TA)p73 and DeltaTAp73--exhibiting tumour suppressor gene and oncogene properties, respectively. The authors examined their expression status in high- and low-grade adult gliomas. Isoform-specific real-time reverse transcription-polymerase chain reaction was used for the analysis of Tp73 isoform transcript expression in a series of 51 adult patients harbouring glial tumours, in order to compare tumour grades with each other, and with non-tumoural samples obtained from epileptic patients as well. Our data demonstrate increase of TAp73 and DeltaTAp73 transcript levels at onset and early stage of the disease. We also show that DeltaEx2-3 isoform expression in low-grade tumours anticipates clinical and imaging progression to higher grades, and correlates to the patients' survival. Expression levels of P1 promoter generated Tp73 isoforms--and particularly DeltaEx2-3--indeed allow for prediction of the clinical progression of low-grade gliomas in adults. Our data are the first such molecular biology report regarding low-grade tumours and as such should be of help for sound decision-making. PMID:17047653

    This study explored third-grade elementary students' conceptions of nature of science (NOS) over the course of an entire school year as they participated in explicit-reflective science instruction. The Views of NOS-D (VNOS-D) was administered pre instruction, during mid-school year, and at the end of the school year to track growth in understanding over time. The Young Children's Views of Science was used to describe how students conversed about NOS among themselves. All science lessons were videotaped, student work collected, and a researcher log was maintained. Data were analyzed by a team of researchers who sorted the students into low-, medium-, and high-achieving levels of NOS understandings based on VNOS-D scores and classwork. Three representative students were selected as case studies to provide an in-depth picture of how instruction worked differentially and how understandings changed for the three levels of students. Three different learning trajectories were developed from the data describing the differences among understandings for the low-, medium-, and high-achieving students. The low-achieving student could discuss NOS ideas, the medium-achieving student discussed and wrote about NOS ideas, the high-achieving student discussed, wrote, and raised questions about NOS ideas.

    Previous studies with children have demonstrated inhibition difficulties associated with prematurity, but the question of potentially catching up with a delay in inhibition processes before adolescence still remains. Moreover, preterm adolescents are more at risk than their term-born peers for presenting behavioral problems such as emotional difficulties and attention deficit/hyperactivity disorder. In addition to examining response inhibition, this study addressed, for the first time, the impact of an emotional context on response inhibition abilities and its relation to behavioral problems in late school-aged preterm children. Fifty-eight preterm children aged 9-12 years were compared with 61 controls on two versions of a stop-signal task, the Delay Frustration Task, and the Strengths and Difficulties Questionnaire. Results showed general difficulties in inhibiting a response, rather than a specific impact of emotional context in preterm children. Compared with controls, these children exhibited more and longer button presses in a delay situation, as well as faster go reaction times associated with lower probability of inhibition in the stop-signal tasks. These difficulties reflected impulsivity and were associated with higher hyperactivity/inattention and conduct problems. Additionally, intrauterine growth restriction was found to be an additional perinatal risk factor for hyperactivity/inattention symptoms. These findings suggest that remaining inhibition difficulties in the preterm population at preadolescence could reveal increasing behavioral issues. PMID:25569693

    Defining the aggressiveness and growth rate of a malignant cell population is a key step in the clinical approach to treating tumor disease. The correct grading of breast cancer (BC) is a fundamental part in determining the appropriate treatment. Biological variables can make it difficult to elucidate the mechanisms underlying BC development. To identify potential markers that can be used for BC classification, we analyzed mRNAs expression profiles, gene copy numbers, microRNAs expression and their association with tumor grade in BC microarray-derived datasets. From mRNA expression results, we found that grade 2 BC is most likely a mixture of grade 1 and grade 3 that have been misclassified, being described by the gene signature of either grade 1 or grade 3. We assessed the potential of the new approach of integrating mRNA expression profile, copy number alterations, and microRNA expression levels to select a limited number of genomic BC biomarkers. The combination of mRNA profile analysis and copy number data with microRNA expression levels led to the identification of two gene signatures of 42 and 4 altered genes (FOXM1, KPNA4, H2AFV and DDX19A) respectively, the latter obtained through a meta-analytical procedure. The 42-based gene signature identifies 4 classes of up- or down-regulated microRNAs (17 microRNAs) and of their 17 target mRNA, and the 4-based genes signature identified 4 microRNAs (Hsa-miR-320d, Hsa-miR-139-5p, Hsa-miR-567 and Hsa-let-7c). These results are discussed from a biological point of view with respect to pathological features of BC. Our identified mRNAs and microRNAs were validated as prognostic factors of BC disease progression, and could potentially facilitate the implementation of assays for laboratory validation, due to their reduced number.

    The objective of this study was to investigate the effects of graded levels of isomaltooligosaccharides (IMO) on the performance, immune function and intestinal microflora and intestinal mucosal morphology of weaned pigs. In a 28-day experiment, one hundred eighty, twenty eight-day-old, crossbred (Duroc×Large White×Landrace), weaned pigs, with an initial body weight of 8.19±1.45 kg, were fed either an unsupplemented corn-soybean meal based diet or similar diets supplemented with 0.2%, 0.4%, 0.6%, or 0.8% IMO added at the expense of corn. Each treatment was replicated six times with six pigs (three barrows and three gilts) per pen. From day 0 to 14, weight gain was linearly increased (p<0.05), while gain:feed (p<0.05) was linearly improved and diarrhea rate (p = 0.05) linearly declined as the IMO level increased. On d 14, the level of the immunoglobulins IgA, IgM, and IgG in the serum of pigs were linearly increased (p<0.05) with increasing IMO supplementation. Interleukin-6 (IL-6) was linearly (p<0.05) and quadratically (p<0.05) decreased as IMO intake increased. From day 15 to 28, there was a trend for weight gain to be linearly increased, and IL-2 was linearly (p<0.05) increased as IMO supplementation increased on d 28. Over the entire experiment, weight gain was linearly increased (p<0.05), while gain:feed (p<0.05) was linearly improved and diarrhea rate (p<0.05) was linearly decreased as the IMO level increased. Supplementation with IMO had no effect on the intestinal microflora of pigs in the ileum and cecum of pigs, as well as the villus height and crypt depth in the ileum and jejunum (p>0.05). These results indicate that dietary inclusion of IMO increases weight gain, gain:feed and enhanced the immune status of pigs, and could be a valuable feed additive for use in weaned pigs, particularly during the period immediately after weaning.

    Canned sardines are a ready-to-use fish product with excellent nutritional properties owing to its high n-3 long-chain PUFA content, mainly EPA (20 : 5n-3) and DHA (22 : 6n-3). The present study aimed to assess the effect of two dosages of canned sardines, recommended for the primary and secondary prevention of human CVD, on the inflammatory marker concentrations and fatty acid composition of erythrocytes and key metabolic tissues (liver, muscle, adipose tissue and brain) in the rat model. Wistar rats were fed a diet containing 11 % (w/w) of canned sardines (low-sardine (LS) diet) and a diet containing 22 % (w/w) of canned sardines (high-sardine (HS) diet) for 10 weeks. Daily food intake, weight gain, and organ and final body weights were not affected by the dietary treatments. The concentrations of total cholesterol, HDL-cholesterol and LDL-cholesterol decreased in both the LS and HS groups, while those of alanine aminotransferase and adiponectin increased. The concentrations of IL-1β increased only with the highest dosage of sardine. The dose-dependent influence of the graded levels of EPA+DHA was tissue specific. Compared with that of other tissues and erythrocytes, the fatty acid composition of the brain was less affected by the canned sardine-supplemented diets. In contrast, the retroperitoneal adipose tissue was highly responsive. The deposition ratios of EPA and DHA indicated that the LS diet was optimal for DHA deposition across the tissues, except in the retroperitoneal adipose tissue. Taken together, our findings indicate that a LS diet positively affects plasma lipid profiles and inflammatory mediators, whereas a HS diet has contradictory effects on IL-1β, which, in turn, is not associated with variations in the concentrations of other pro-inflammatory cytokines. This finding requires further investigation and pathophysiological understanding. PMID:24775714

  6. A study of student attitudes toward physics and classroom environment based on gender and grade level among senior secondary education students in Indonesia

    NASA Astrophysics Data System (ADS)

    Chaerul, Andrie

    The main purposes of the present study are to investigate the differences on student's attitudes toward physics and their perceptions regarding classroom climate during physics classes based on gender and grade level. In addition, the study also explores female students' opinions about physics, and examines to what extent this factor might influence their decision to choose or not to choose physics or physics-related fields for their career choices in the future. A group of approximately 864 male and female students, equally proportioned by gender, were assigned to take part in this study. Two standardized instruments, namely the Individualized Classroom Environment Questionnaire (ICEQ) and the Test of Science Related Attitudes (TOSRA), have been employed to collect data. A combination of quantitative and qualitative methods was used to analyze the collected data resulting from the questionnaires as well as from the interviews. The study found, first, regardless of their gender and grade level differences, students expected a more positive classroom climate during learning physics. Also, it has been found that male students experience a more positive classroom environment than female students. Second, the study found that male students do show more positive attitudes toward physics than their female counterparts. Meanwhile, twelfth-grade students show a more positive attitude toward physics than eleventh-graders. Third, the study found that most female students do not like physics based on several reasons such as physics is a hard, monotonous and boring subject. Although eleventh-grade female students do not like physics, most of them intended to choose science as their major in the next grade. Surprisingly, a majority of twelfth-grade female students who are majoring in science have no intention to choose physics or physics-related subjects either for their prospective major at the university or for their career choices in the future.

    The achievement of recommended levels (≥ 30 min/day) of school moderate-to-vigorous physical activity (MVPA) is paramount to decrease risk of chronic disease in children from low-income families. The purpose of this study was to examine the predictors and grade-level trends of school day MVPA achievement in low-income children. Data were collected during the Fall of 2014 on 1232 children (Mean age = 8.8 ± 1.6 years; 625 girls, 607 boys) recruited from three low-income schools from the state of Utah in the U.S. Children wore pedometers for one school week and a stratified random subsample (n = 533) also wore accelerometers to record sedentary time and MVPA. Generalized linear mixed models were employed to calculate odds ratios for achieving school MVPA standards (≥ 30 min/day) from various predictors and to determine odds of achievement across grade levels, accounting for school and classroom clustering. Odds of meeting MVPA standards were 3 times greater if a student achieved at least 6000 steps during the school day (p < 0.01), and were 55% lower for every 1% increase in sedentary time (p < 0.001). Older children had 26% lower odds of meeting the recommended levels of MVPA compared to children in an immediately younger grade level (p < 0.05). A significant proportion of MVPA variance was explained by classroom and school affiliation (Rho = 0.09 to 0.54, p < 0.001). Daily steps, sedentary times, grade level, and classroom and school affiliation associate with school MVPA achievement in low-income children. PMID:26844162

    2016-06-01

    The impact of graded levels of day length on turkey health and behavior was determined in hens and toms raised to 18 wk of age. Birds were allocated to one of 4 lighting treatments (trt) providing 14 (14L), 17 (17L), 20 (20L), and 23 (23L) h of day length. Two time-replicated trials were completed with each, providing 2 rooms per lighting trt and each room having 3 hen (n = 720) and 3 tom (n = 480) pens. Data collection included gait score (GS), the incidence of footpad dermatitis (FPD), breast buttons and blisters, ocular size and pressure (males only), and behavioral observations (males only). Data were analyzed using SAS 9.3 based on a completely randomized design nested within 4 lighting trt. Regression analysis established relationships between response criteria and day length. Differences were considered significant at P ≤ 0.05 and trends noted at P ≤ 0.10. Gait score, FPD, and the incidence of breast buttons and blisters were assessed on 5 birds per pen at 11 and 17 wk of age. Average GS increased linearly with day length at 11 and 17 wk for both hens and toms, but the effect was larger in toms. Day length did not affect FPD, but more lesions and severe scores were found for hens than toms. The presence of breast buttons and blisters increased linearly with day length (11 wk) with the effect on blisters predominately seen in toms. Eye weight and size increased with increasing day length at 12 and 18 wk. Ocular pressure was not affected by day length. Infrared cameras recorded tom behavior over a 24 h period, and behaviors were classified over 10-min intervals using a scan sampling technique at 11 and 17 wk. Alterations in behavioral repertoire were observed with a linear increase in inactive resting and a linear decrease in standing, walking, preening, and environmental and feather pecking behaviors with increased day length. To conclude, day length affected bird mobility and incidence of breast blisters in an age- and gender-specific manner, and time

  2. How is Science Learning Assessed at the Postsecondary Level? Assessment and Grading Practices in College Biology, Chemistry and Physics

    NASA Astrophysics Data System (ADS)

    Goubeaud, Karleen

    2010-06-01

    The role of assessment in higher education is gaining importance as accountability requirements intensify and as assessments are increasingly recognized as having potential to improve teaching and learning. During the last two decades, educators have begun implementing a wider variety of assessment types including alternative and student-centered assessment practices. However, few research studies have examined the extent that college science faculty use such practices. This large-scale descriptive study utilized a nationally representative sample of higher education faculty from the US Department of Education to examine the assessment and grading practices of college science faculty from 2 and 4-year higher education institutions. When data was disaggregated by science discipline, statistically significant differences were found among physics, chemistry and biology faculty's assessment and grading practices. Biology faculty used a larger repertoire of assessment types overall, and used assessments that have potential to enhance the learning process more than chemistry and physics faculty. Physics and chemistry faculty graded on a curve more often and used competency-grading practices less often than biology faculty. Assessment practices that could be considered formative with potential to promote student learning appear to be underutilized by all science faculty.

    This report details the initial comparison of mechanical strength properties between the cylindrical nuclear-grade graphite specimens irradiated in the second Advanced Graphite Creep (AGC-2) experiment with the established baseline, or unirradiated, mechanical properties compiled in the Baseline Graphite Characterization program. The overall comparative analysis will describe the development of an appropriate test protocol for irradiated specimens, the execution of the mechanical tests on the AGC-2 sample population, and will further discuss the data in terms of developing an accurate irradiated property distribution in the limited amount of irradiated data by leveraging the considerably larger property datasets being captured in the Baseline Graphite Characterization program. Integrating information on the inherent variability in nuclear-grade graphite with more complete datasets is one of the goals of the VHTR Graphite Materials program. Between “sister” specimens, or specimens with the same geometry machined from the same sub-block of graphite from which the irradiated AGC specimens were extracted, and the Baseline datasets, a comprehensive body of data will exist that can provide both a direct and indirect indication of the full irradiated property distributions that can be expected of irradiated nuclear-grade graphite while in service in a VHTR system. While the most critical data will remain the actual irradiated property measurements, expansion of this data into accurate distributions based on the inherent variability in graphite properties will be a crucial step in qualifying graphite for nuclear use as a structural material in a VHTR environment.

    INTRODUCTION: Pyrosequencing is a method that allows MGMT methylation to be measured in a quantitative manner. MGMT methylation, along with 1p/19q co-deletion and IDH1 mutation, is an important biomarker in high grade gliomas. MGMT methylation indicates an improved response to temozolomide chemotherapy; patients with 1p/19q co-deleted anaplastic oligodendrogliomas benefit from the addition of chemotherapy to radiotherapy. Aim: To compare the average MGMT promoter methylation level of high grade gliomas and correlate it with other clinical parameters and markers including IDH1&2 mutation and 1p/19q co-deletion. METHOD: For 171 high grade gliomas MGMT methylation analysis was performed by pyrosequencing, mutations to IDH1 and IDH2 genes were also detected by pyrosequencing, or immunohistochemistry (n = 166). Screening for 1p/19q deletion was by fluorescence in situ hybridisation (n = 46). Statistical analysis was performed using R-Stats v2.15.2. RESULTS: The results show that higher methylation was correlated with lower grade and mutation to either IDH1 or IDH2 (27.0% vs. 16.6% p = 0.008; and 27.5 vs. 16.1 p = 0.002 respectively). Interestingly 1p/19q co-deletion versus non co-deletion was associated with a particularly high level of methylation (42.2% vs. 17.7% p = 0.001). No significant differences were seen for age or gender. CONCLUSION: The results offer a potential explanation for the improved prognosis seen in glioma patients with 1p/19q co-deletion and when combined with IDH mutation status may provide an extra control to confirm true 1p/19q co-deletion.

    Present work describes the bioleaching potential of metals from low-grade mining ore containing smithsonite, sphaerocobaltite, azurite and talc as main gangue minerals with adapted consortium of Sulfobacillus thermosulfidooxidans strain-RDB and Thermoplasma acidophilum. Bioleaching potential improved markedly by added energy source, acid preleaching and adaptation of microbial consortium with mixed metal ions. During whole leaching period including acid preleaching stage of 960 h and bioleaching stage of 212 days about 76% Co, 70% Zn, 84% Cu, 72% Ni and 63% Fe leached out. PMID:21947702

    The Human papillomavirus is responsible for the most common sexually transmitted infection and is also known to be an oncogenic virus that is associated with cervical, anogenital, and head-neck cancers. The present study aims to assess whether oxidative DNA damage is correlated with the grade of HPV-related lesions. Moreover, we evaluated clinical data and unhealthy lifestyles to verify their possible influence on the genesis of oxidative DNA damage in cervical cells. We quantified the amount of 8-Oxo-2'-deoxyguanosine in DNA as a biomarker of oxidative damage in women with and without HPV infection. We also correlated oxidative damage with different stages of cervical lesions and available clinical data (e.g., HPV genotypes). To identify HPV infections, in which proteins with a transforming potential are produced, we performed a qualitative detection of HPV E6/E7 mRNA. Our results showed greater oxidative damage in HPV-related dysplastic cervical lesions compared to samples with normal cytology, especially in women with high-grade squamous intraepithelial lesions. The latter showed a closed link with high-risk HPV genotypes. Reactive oxygen species can induce DNA double-strand breaks in both the host DNA and in the circular viral episome; this could facilitate the integration of the virus, promoting HPV carcinogenesis. Therefore, in HPV-infected women, it could be useful to reduce additional resources of reactive oxygen/nitrogen species (RONS) with a healthy lifestyle. PMID:26174792

  11. An investigation of gender and grade-level differences in middle school students' attitudes about science, in science process skills ability, and in parental expectations of their children's science performance

    The primary purpose of the study was to examine different variables (i.e. science process skill ability, science attitudes, and parents' levels of expectation for their children in science, which may impinge on science education differently for males and females in grades five, seven, and nine. The research question addressed by the study was: What are the differences between science process skill ability, science attitudes, and parents' levels of expectation in science on the academic success of fifth, seventh, and ninth graders in science and do effects differ according to gender and grade level? The subjects included fifth, seven, and ninth grade students ( n = 543) and their parents (n = 474) from six rural, public elementary schools and two rural, public middle schools in Southern Mississippi. A two-way (grade x gender) multivariate analysis of variance (MANOVA) was used to determine the differences in science process skill abilities of females and males in grade five, seven, and nine. An additional separate two-way multivariate analysis of variance (grade x gender) was also used to determine the differences in science attitudes of males and females in grade five, seven, and nine. A separate analysis of variance (PPSEX [parent's gender]) with the effects being parents' gender was used to determine differences in parents' levels of expectation for their childrens' performance in science. An additional separate analysis of variance (SSEX [student's gender]) with the effects being the gender of the student was also used to determine differences in parents' levels of expectation for their childrens' performance in science. Results of the analyses indicated significant main effects for grade level (p < .001) and gender (p < .001) on the TIPS II. There was no significant grade by gender interaction on the TIPS II. Results for the TOSRA also indicated a significant main effect for grade (p < .001) and the interaction of grade by sex ( p < .001). On variable ATT 5

    Calorie restriction (CR) delays the onset of age-related disease and extends lifespan in a number of species. When faced with reduced energy supply animals need to lower energy demands, which may be achieved in part by reducing physical activity (PA). We monitored changes in PA using implanted transmitters in male C57BL/6 mice in response to graded levels of CR (10 to 40%) or matched levels of graded protein restriction (PR) for 3 months. Mice were fed at lights out and ad libitum controls were limited to dark-phase feeding (12AL) or 24hr/day. Total daily PA declined in a non-linear manner over the first 30 days of CR or PR, remaining stable thereafter. Total daily PA was not related to the level of CR or PR. Total daily PA over the last 20 days of restriction was related to circulating leptin, insulin, tumor necrosis factor-α (TNF-α) and insulin-like growth factor (IGF)-1 levels, measured after 3 months. Mice under restriction showed a high level of activity in the 2hrs before feeding (food anticipatory activity: FAA). FAA followed a complex pattern, peaking around day 20, falling on ∼day 37 then increasing again. FAA was also positively related to the level of restriction and inversely to leptin, insulin, TNF-α and IGF-1. Non-FAA, in contrast, declined over the period of restriction, generally more so in mice under greater restriction, thereby offsetting to some extent the increase in FAA. Mice under PR displayed no changes in PA over time or in comparison to 12AL, and showed no increase in FAA. PMID:27007156

    The main purpose of this study was to explore the factors mediating the translation of second grade teachers' nature of science (NOS) views into classroom practice after completing a graduate level NOS course. Four second grade in-service elementary teachers comprised the sample of this study. Data were collected from several sources during the course of this study. The primary data sources were (a) assessment of the elementary teachers' NOS views before and after the graduate level NOS course using the Views of Nature of Science Questionnaire Version B (VNOS-B) (Lederman et al., 2002) coupled with interviews, and (b) a classroom observation and videotaped recording of the elementary teachers' best NOS lessons coupled with interview. We identified three distinct but related factors that mediated the translation of NOS views into classroom practice: the teachers' perspectives about the developmental appropriateness of the NOS aspect, the teachers' selection of target NOS aspects, and the relative importance placed by teachers on each NOS aspect.

    Background A predictive marker of bevacizumab activity is an unmet medical need. We evaluated the predictive value of selected circulating prebiomarkers involved in neoangiogenesis and invasion on patient outcome in recurrent high-grade glioma treated with bevacizumab. Methods Analyzed in plasma were a set of 11 prebiomakers of interest (vascular endothelial growth factor receptor [VEGF]; VEGF receptor 2; basic fibroblast growth factor; stromal cell derived factor 1; placenta growth factor; urokinase-type plasminogen activator; plasminogen activator inhibitor 1; matrix metalloproteinases 2, 7, and 9; and adrenomedulline), using ELISA, at baseline and 2 weeks after bevacizumab initiation in a prospective cohort of 26 patients (Cohort 1). Correlations were validated in a separate retrospective cohort (Cohort 2; n = 50) and tested in cohort patients treated with cytotoxic agents without bevacizumab (Cohort 3; n = 34). Dosages were correlated to objective response, progression-free survival (PFS), and overall survival (OS). Results In Cohort 1, high MMP2 baseline level was associated with a probability of objective response of 83.3% versus 15.4% for low MMP2 level (P = .001). In multivariate analysis, baseline level of MMP2 correlated with PFS (hazard ratio, 3.92; 95% confidence interval [CI]:1.46–10.52; P = .007) and OS (hazard ratio, 4.62; 95% CI: 1.58–13.53; P = .005), as decrease of VEGF (P = .038 for PFS and P = .013 for OS) and MMP9 (P = .016 for PFS and P = .025 for OS). In Cohort 2, MMP2, but not MMP9, confirmed its predictive significance. In Cohort 3, no association was found between MMP2, MMP9, and outcome. Conclusion In patients with recurrent high-grade glioma treated with bevacizumab, but not with cytotoxic agent, high MMP2 plasma levels are associated with prolonged tumor control and survival. MMP2 should be tested in randomized clinical trials that evaluate bevacizumab efficacy, and its biological role reassessed. PMID:24327581

    The relationship between the size of the substituents of aryl groups in a series of fifteen 6,9,12,15,18-pentaaryl-1-hydro[60]fullerenes and the solid-state structures and packing motifs of these compounds has been analyzed. Pentaarylfullerenes have a characteristic “badminton shuttlecock” shape that causes several derivatives to crystallize into columnar stacks. However, many pentaarylfullerenes form non-stacked structures with, for example, dimeric, layered, diamondoid, or feather-in-cavity relationships between molecules. Computational modeling gave a qualitative estimate of the best shape match between the ball and socket surfaces of each pentaarylfullerene. The best match was for pentaarylfullerenes with large, spherically shaped para-substituents on the aryl groups. The series of pentaarylfullerenes was characterized by single-crystal X-ray diffraction. A total of 34 crystal structures were obtained as various solvates and were categorized by their packing motifs.

    In this paper, oxidation behavior of 9-12% Cr steels P91 and HCM12A is studied in air and in a mixture of air and water vapor. Comparison is made between these steels in uncoated condition and coated with aluminum diffusion coating by a slurry method. Oxidation tests were carried out at 550, 600, and 650 °C for a discontinued duration of 1000 h; every 250 h the specimens were slowly cooled to room temperature and weighed. SEM + EDS and XRD characterization were performed after 500 and 1000 h. The results showed that oxidation rate of uncoated P91 and HCM12A was significantly higher in the mixture of air and water vapor than in air. Oxidation resistance of the studied materials improved substantially when they were aluminized.

    Chronic myeloid leukemia (CML) is a hematopoietic stem cell disorder included in the broader diagnostic category of myeloproliferative neoplasms, associated with fusion by BCR gene at chromosome 22q11 to ABL1 gene at chromosome 9q34 with the formation of the Philadelphia (Ph) chromosome. In 2–10% of CML cases, the fusion gene arises in connection with a variant translocation, involving chromosomes 9, 22, and one or more different chromosomes; consequently, the Ph chromosome could be masked within a complex chromosome rearrangement. In cases with variant Ph translocation a deletion on der(9) may be more frequently observed than in cases with the classical one. Herein we describe a novel case of CML with complex variant Ph translocation involving chromosomes 9, 12, and 22. We present the hematologic response and cytogenetic response after Imatinib treatment. We also speculated the mechanism which had originated the chromosome rearrangement. PMID:25045550

    Longing can be defined as a secondary emotion, as a blend of the primary emotions of love and sadness. There are several possible dimensions and aspects of longing (O. Holm, 1999). Both age and gender differences are well documented in earlier research on other emotions. In the present investigation, 122 girls and 120 boys, ages 9, 12, and 15 years, in compulsory school in Sweden, answered a questionnaire about dimensions and aspects of their own longing. The results showed both age and gender differences. Girls, especially in the 15-year-old group, experienced longing significantly more than boys. The results were interpreted as generally in accordance with what is known from earlier research on other emotions. PMID:11728061

    An experiment was conducted to determine the optimum inclusion levels of dried broiler litter (DBL) as a substitute for cottonseed cake (CSC) in fattening diets for Brangus steers. Thirty Brangus steers were randomly allocated to five groups of six animals each. Each group was fed one of the experimental diets which had CSC substituted for DBL at levels of 0 (DBL0), 50 (DBL50), 100 (DBL100), 150 (DBL150) and 200 g/kg (DBL200). Average daily gain (ADG), dry matter intake and live weight gain (LWG) were measured over a period of 90 days, and the results were analysed using the MIXED procedures of SAS. Linear and quadratic effects of DBL inclusion on dry matter intake, LWG and ADG were also determined. Results showed interactions between diet and time that significantly affected ADG and LWG (p < 0.05). Both ADG and LWG decreased with increases in DBL inclusion with the depressed performance becoming more pronounced with time. Linear and non-linear decreases in LWG and ADG, respectively, were observed with increasing levels of DBL. The DBL50 diet resulted in performance that was similar to DBL50 and was 4% cheaper. Broiler litter can be used as a supplement for conventional protein sources, but at higher inclusion levels, it needs to be augmented by increased fermentable energy. PMID:25894822

    Thiocyanate concentrations of serum, liver, kidney, spleen and longissimus dorsi were determined in 64 growing Large White x Landrace pigs offered 8 experimental isocaloric diets containing different levels of cassava peel and crude protein. Cassava peel increased serum thiocyanate on day 60 (P less than 0.01) and day 90 (P less than 0.01) of the trial, while the crude protein level increased it (P less than 0.05) on days 30 and 90, respectively. Interaction of the two factors was significant on day 30 (P less than 0.05) and day 90 (P less than 0.05). There was a correlation between cyanide intake and serum thiocyanate level. Coefficient of determination revealed that cyanide alone accounted for 28.5; 60.6 and 48.8% variation in serum thiocyanate on days 30, 60 and 90, respectively. Liver, spleen and longissimus dorsi thiocyanate were affected by dietary protein intake (P less than 0.05). Thiocyanate concentration was higher (P less than 0.05) on cassava peel diet. Generally, crude protein at 5% reduced organ and muscle thiocyanate concentrations. A diet containing 112.2-117.3 mg/kg hydrocyanic acid (HCN) affected serum but not organ and muscle thiocyanate in protein-sufficient diets. PMID:6506092

    Animals have to adjust their activities when faced with caloric restriction (CR) to deal with reduced energy intake. If CR is pronounced, allostasis can push individuals into alternate physiological states which can result in important health benefits across a wide range of taxa. Here we developed a new approach to determine the changes in behavioural phenotype associated with different levels of CR. We exposed C57BL/6 male mice to graded CR (from 0 to 40%) for three months and defined their behavioural phenotype using hidden Markov models of their movement and body temperature. All 40% CR mice exhibited a state-shift in behavioural phenotype and only some exposed to 30% CR did. We show for the first time that mice changed their activity characteristics rather than changed their activities. This new phenotyping approach provides an avenue to determine the mechanisms linking CR to healthspan. PMID:26306002

  10. A comparison of the oral and silent reading methods of standardized science test delivery on the performance level of fifth-grade African American students

    NASA Astrophysics Data System (ADS)

    Merenda, Gloria Louise

    This study compared two methods of standardized test administration, oral delivery using an audio tape and the standard silent reading by the student, on the performance level (test score) and science understanding (right answer/right reason) of urban fifth grade African American students. The effect of reading ability, special needs, and socioeconomic status were also examined as possible confounding variables. A randomized post-test only control group design was used with data for the sample (N = 106) collected from student files at two Detroit Public Schools, which included the Michigan Education Assessment Program (MEAP) reading and science scores. In addition, face-to-face interviews were completed with a small subsample to determine reasoning for selecting their answers. Six hypotheses were developed to determine if there were significant differences in science performance level and understanding in fifth grade urban African American students when the standardized science test, MEAP, Area Specific Portions, Physical Science and Earth/Space Science, were delivered orally, using the audio tape, and silently, which is the present standard delivery method. Significant differences in scores were found favoring the oral over the silent test group. A significant association was also found for reading and science MEAP scores, with students who had higher scores on the reading test achieving higher scores on the science test. Although socioeconomic status did not appear to result in differential outcomes among the students, a significant interaction was found between test administration type and socioeconomic status. The conclusion that was reached was that students who have difficulty in reading the printed material could benefit from having standardized tests administered orally (except for reading tests).

  11. Gender and grade level differences in interest, perceived personal capacity, and involvement in technology and engineering-related activities

    NASA Astrophysics Data System (ADS)

    Weber, Katherine

    Society has become increasingly technological, demanding that all citizens have a level of technological literacy. In order for this to occur, both males and females must participate in technology-related activities to achieve an adequate level of technological literacy. Despite individual and organizational efforts, females continue to be underrepresented in STEM-related occupations. This is especially true in many engineering-related fields. Jolly, Campbell and Perlman (2004) devised the Engagement, Capacity, and Continuity (ECC) Trilogy. With each factor of the trilogy in place, Jolly et al. found that female representation increased in STEM. The purpose of this study was to identify whether Jolly, Campbell, and Perlman's (2004) Engagement, Capacity, and Continuity Trilogy could be utilized by teachers in technology and engineering program settings to examine their students' interest (engagement), perceived personal capacity (capacity), as well as participation in technology and engineering-related activities (continuity). This descriptive study surveyed 556 female and male middle school and high school students enrolled in Technology and Engineering classes. The results of this study revealed that when students indicated a high interest and a high perceived personal capacity, and when they participated in technology and engineering-related activities, they also indicated an interest in pursuing a career in engineering. The results also revealed that the male students continued to be encouraged by technology and engineering teachers, parents, and counselors to pursue a career in engineering more than female students. This startling finding should draw some concern; both males and females should be equally encouraged to consider engineering as a career. Technology and engineering teachers should implement activities that appeal to both males and females. Parents should encourage their daughters to participate in informal learning opportunities to nurture their

    In December 1987, Nebraska was selected by the Central Interstate Compact (CIC) Commission as the host state for the construction of a low-level radioactive waste disposal facility. After spending a year in the site screening process, the Compact`s developer, US Ecology, selected three sites for detailed site characterization. These sites were located in Nemaha, Nuckolls and Boyd Counties. One year later the Boyd County site was selected as the preferred site and additional site characterization studies were undertaken. On July 29, 1990, US Ecology submitted a license application to the Nebraska Department of Environmental Control (now Department of Environmental Quality-NDEQ). This paper will present issues that the NDEQ has dealt with since Nebraska`s selection as the host state for the CIC facility.

    Proinflammatory cytokines that are produced by helper T cells (Th) regulate immune reactions, facilitate class switching of B cells, and prolong the lifespan of B and T cells. Eradication therapy using antibiotics is sometimes effective against gastrointestinal (GI) malignant lymphoma, suggesting that the tumor development or progression is affected by the inflammatory microenvironment. In the present study, serum samples from 148 patients with various subtypes of malignant lymphoma were tested for 11 proinflammatory Th1/Th2 cytokines. In the comparison by subtype or GI lesions, serum interleukin (IL)-8 (P = 6.7E−05), IL-4 (P = 7.5E−05), and IL-1β (P = 0.0043) levels showed significant differences among subtypes, being particularly elevated in follicular lymphomas (FL) and mucosa-associated lymphoid tissue (MALT) lymphomas. Serum IL-8 levels were elevated in GI-FL and MALT lymphomas, and serum IL-4 and IL-1 β levels were elevated in MALT lymphomas. These findings show that GI low-grade B-cell lymphoma could develop against the background of an inflammatory microenvironment. Thus, these cytokines may be useful as diagnostic markers and could provide new insights into tumor development. PMID:26674732

    In order to find out the optimum level of crude protein (CP) in the diet of captive Lady Amherst's pheasants (LAP) on molt, 18 male birds were randomly distributed into three groups of six each in an experiment based on completely randomized block design. The CP content of the diets of birds in groups I, II, and III was 13.4, 16.5, and 19.1%, respectively. Intake and apparent balance of nitrogen increased linearly (P < 0.001) as CP content of the diet increased. Intake and utilization of energy, calcium, and phosphorous were similar among groups. Body mass change and growth rate of feathers were significantly (P < 0.01) lower in group I as compared to groups II and III. There was a positive co-relationship between ME intake and change in body weight (R(2) = 0.89, F = 126.4, P < 0.001). Regression analysis indicates that LAP can maintain body mass when ME supply is 122.2 Kcal/kg BW(0.75)/d. Linear relationships between intake and apparent retention of N, Ca, and P as expressed on mg/kg BW(0.75)/d were all significant. Apparent nitrogen retention, and mean feather growth rate was lower in birds fed diet containing 13.4% CP. Feeding of the diets containing 16.5% CP resulted in improved retention of nitrogen, and mean feather growth rate. Further increase in dietary concentration of CP to 19.1% showed no further improvement. It was concluded that a diet containing 16.5% CP would be optimum for Lady Amherst's pheasants during molt.

    Teachers are expected to improve their planning, instruction, and assessment as they progress through their career. An important component to teachers knowing what to modify in their teaching style is being able to solicit meaningful feedback from students. This mixed-methods study was conducted to provide teachers with a quantitative method to collect data about their teaching using the Constructivist Learning Environment Survey (CLES). Phase 1 allowed students to provide anonymous feedback to their teachers that the teachers could later reflect upon in conjunction with the students' other feedback. Using measures of central tendencies, it was determined that of the five categories of the CLES the area of student negotiation was statistically different from the other categories. While eight teachers had sufficient (n>10) student data to be invited to participate in Phase 2, only five of the teachers choose to participate in a semi-structured interview to further examine the potential differences between teacher and student perception of student negotiation with the curriculum, instruction and assessment that occurs in the classroom. Coding the interview transcripts led to three categories: 1) teaching style (with themes including curriculum, instruction, and assessment, and sub themes of teacher centered and student centered); 2) external pressures (with themes of standards , standardized tests, and socioeconomic conditions); 3) effectiveness of student negotiation (with themes of positive effect or no effect on motivation). The five teachers who participated in Phase 2 had varying levels of awareness and willingness to adjust their classroom curriculum, instruction, and assessment to include student negotiation. All but one teacher, however, saw the value in increasing student negotiation in the classroom and desired to continue to change their teaching to include more student negotiation.

    Epithelial ovarian cancer (EOC) has an innate susceptibility to become chemoresistant. Up to 30% of patients do not respond to conventional chemotherapy [paclitaxel (Taxol®) in combination with carboplatin] and, of those who have an initial response, many patients relapse. Therefore, an understanding of the molecular mechanisms that regulate cellular chemotherapeutic responses in EOC cells has the potential to impact significantly on patient outcome. The mitotic arrest deficiency protein 2 (MAD2), is a centrally important mediator of the cellular response to paclitaxel. MAD2 immunohistochemical analysis was performed on 82 high-grade serous EOC samples. A multivariate Cox regression analysis of nuclear MAD2 IHC intensity adjusting for stage, tumour grade and optimum surgical debulking revealed that low MAD2 IHC staining intensity was significantly associated with reduced progression-free survival (PFS) (p = 0.0003), with a hazard ratio of 4.689. The in vitro analyses of five ovarian cancer cell lines demonstrated that cells with low MAD2 expression were less sensitive to paclitaxel. Furthermore, paclitaxel-induced activation of the spindle assembly checkpoint (SAC) and apoptotic cell death was abrogated in cells transfected with MAD2 siRNA. In silico analysis identified a miR-433 binding domain in the MAD2 3′ UTR, which was verified in a series of experiments. Firstly, MAD2 protein expression levels were down-regulated in pre-miR-433 transfected A2780 cells. Secondly, pre-miR-433 suppressed the activity of a reporter construct containing the 3′-UTR of MAD2. Thirdly, blocking miR-433 binding to the MAD2 3′ UTR protected MAD2 from miR-433 induced protein down-regulation. Importantly, reduced MAD2 protein expression in pre-miR-433-transfected A2780 cells rendered these cells less sensitive to paclitaxel. In conclusion, loss of MAD2 protein expression results in increased resistance to paclitaxel in EOC cells. Measuring MAD2 IHC staining intensity may predict

    Coatings are seen a promising way to improve the corrosion resistance of relatively cheap power plant steels to enable higher steam temperatures than currently in use. In this research, 9-12% Cr steels P91 and HCM12A are coated with aluminium diffusion coating by a slurry method and exposed for 336 hours at 833 K and 883 K to atmospheres containing varying amounts of O2, H2O, HCl and SO2. Corrosion behaviour of the coated steels is compared to that of those steels in an uncoated condition. Characterization is performed by weighing, SEM + EDS and XRD. The results show that corrosion resistance of P91 and HCM12A is significantly improved by the aluminium diffusion coating at high temperatures in atmospheres containing HCl and SO2. The corrosion rate of the aluminized specimens slightly increases with increase in test temperature but remains virtually the same irrespective of the composition of the atmosphere. On the other hand, the corrosion rate of the uncoated specimens is dependent on both the atmosphere and the temperature. The steels undergo active oxidation that results in formation of non-protective, thick and layered scales in HCl containing atmospheres. SO2 addition slightly decreases the corrosion rate although it is anyway higher than that in SO2 containing atmosphere without HCl.

    People process numbers in different formats, such as dot arrays (non-symbolic), Arabic digits and number words (symbolic), and use these representations when performing arithmetic calculations. It remains, however, unclear if and how these various presentation formats affect brain activity during arithmetic. We conducted an fMRI study in 23 typically developing children aged 9-12. The children were asked to subtract numbers up to 10 and had to compare the result to a reference number. Numbers were presented in non-symbolic (dot arrays), as well as symbolic formats (Arabic digits and number words). Our findings suggest that similar brain networks are recruited during arithmetic with different symbolic formats, i.e. Arabic digits and number words. On the other hand, there are clear differences between calculating with symbolic and non-symbolic formats. Specifically, calculating in symbolic formats showed increased activity in angular and supramarginal gyri, whereas arithmetic in the non-symbolic format showed increased activity in middle occipital and superior parietal lobes, as well as in superior frontal gyrus and insula. These differences in brain activity might be explained by differences in the strategies used to solve these arithmetic problems. PMID:27044845

    We present an updated version of the spectroscopic catalogue of white dwarf-main-sequence (WDMS) binaries from the Sloan Digital Sky Survey (SDSS). We identify 938 WDMS binaries within the data releases (DR) 9-12 of SDSS plus 40 objects from DR 1-8 that we missed in our previous works, 646 of which are new. The total number of spectroscopic SDSS WDMS binaries increases to 3294. This is by far the largest and most homogeneous sample of compact binaries currently available. We use a decomposition/fitting routine to derive the stellar parameters of all systems identified here (white dwarf effective temperatures, surface gravities and masses, and secondary star spectral types). The analysis of the corresponding stellar parameter distributions shows that the SDSS WDMS binary population is seriously affected by selection effects. We also measure the Na I λλ 8183.27, 8194.81 absorption doublet and H α emission radial velocities (RV) from all SDSS WDMS binary spectra identified in this work. 98 objects are found to display RV variations, 62 of which are new. The RV data are sufficient enough to estimate the orbital periods of three close binaries.

    With supplemental funding from the National Science Foundation (NSF), students from the University of Delaware's Science Semester course took part in a two-day research cruise in the Delaware Bay Estuary. The Science Semester, an NSF-funded project, is an integrated 15-credit sequence that encompasses the entire course work for the spring semester for approximately 60 sophomore-level elementary education majors. The semester includes the earth, life, and physical science content courses and the education science methods course integrated into one curriculum. In this curriculum, problem-based learning and other inquiry-based approaches are applied to foster integrated understandings of science and pedagogy that future elementary teachers need to effectively use inquiry-based approaches in their classrooms. The research cruise was conducted as part of one of the four major investigations during the course. The investigation focused on Delaware's state marine animal, Limulus polyphemus. It is one of the four remaining species of horseshoe crabs; the largest spawning population of Limulus is found in Delaware Bay. Within the problem- and inquiry-based learning approaches of the Science Semester course, the students became aware that very little data exists on the benthic habitat of Limulus polyphemus. In order to learn more about this habitat, a cohort of seven students from the course was recruited as part of the scientific party to take part in the research cruise to collect data on the floor of Delaware Bay. The data included: multibeam bathymetry/backscatter data, grab samples of bay bottom sediments, and CTD profiles. Prior to the cruise, all students in the course took part in laboratory exercises to learn about topographic maps and navigation charts using the Delaware Bay area as the region of study. While "at-sea", the cruise participants sent the ship's latitude and longitude positions as a function of time. The positions were used by the on-land students to

    Using the ten-year (2000-2009) Data-Assimilation (DA) quality Terra MODIS and MISR aerosol products, as well as 7 years of Aqua MODIS, we studied both regional and global aerosol trends over oceans. This included both operational and data assimilation grade versions of the products. After correcting for what appears to be aerosol signal drift from the radiometric calibration of both MODIS instruments, we found MODIS and MISR agreed on a statistically negligible global trend of ±0.003/per decade. Our study also suggests that AODs over the Indian Bay of Bengal, east coast of Asia, and Arabian Sea show increasing trends of 0.07, 0.06, and 0.06 per decade for MODIS, respectively. These regional trends are considered as significant with a confidence level above 95%. Similar increasing trends were found from MISR, but with less relative magnitude. These trends reflect respective increases in the optical intensity of aerosol events in each region: anthropogenic aerosols over the east coast of China and Indian Bay of Bengal; and a stronger influence from dust events over the Arabian Sea. Negative AOD trends, low in confidence levels, are found off Central America, the east coast of North America, and the west coast of Africa, which indicate that longer periods of observation are necessary to be conclusive.

    We evaluated the association of total bilirubin with post-percutaneous coronary intervention (PCI) coronary blood flow and in-hospital major adverse cardiac events (MACEs) in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary PCI. A total of 536 consecutive patients with STEMI (male 79%, mean age = 59.9 ± 12.6 years) admitted within 6 hours from symptom onset were enrolled. Patients were divided into 2 groups based on the thrombolysis in myocardial infarction (MI) flow grade. In-stent thrombosis, nonfatal MI, and in-hospital mortality were significantly higher in no-reflow group (P = .007, P = .002, and P < .001, respectively). On multivariate regression, the total bilirubin levels remained independent predictors of no-reflow (odds ratio [OR] 1.586, 95% confidence interval [CI] 1.02-2.47; P = .042) and in-hospital MACE (OR 1.399, 95% CI 1.053-1.857; P = .020). Serum bilirubin levels were independently associated with no-reflow and in-hospital MACE in patients with STEMI undergoing primary PCI. PMID:23378197

    Women persistently infected with human papillomavirus (HPV) type 16 are at high risk for development of cervical intraepithelial neoplasia grade 3 or cervical cancer (CIN3+). We aimed to identify biomarkers for progression to CIN3+ in women with persistent HPV16 infection. In this prospective study, 11,088 women aged 20-29 years were enrolled during 1991-1993, and re-invited for a second visit two years later. Cervical cytology samples obtained at both visits were tested for HPV DNA by Hybrid Capture 2 (HC2), and HC2-positive samples were genotyped by INNO-LiPA. The cohort was followed for up to 19 years via a national pathology register. To identify markers for progression to CIN3+, we performed microarray analysis on RNA extracted from cervical swabs of 30 women with persistent HPV16-infection and 11 HPV-negative women. Six genes were selected and validated by quantitative PCR. Three genes were subsequently validated within a different and large group of women from the same cohort. Secondly, Kaplan-Meier and Cox-regression analyses were used to investigate whether expression levels of those three genes predict progression to CIN3+. We found that high transcript levels of TMEM45A, SERPINB5 and p16INK4a at baseline were associated with increased risk of CIN3+ during follow-up. The hazard ratios of CIN3+ per 10-fold increase in baseline expression level were 1.6 (95% CI: 1.1-2.3) for TMEM45A, 1.6 (95% CI: 1.1-2.5) for p16INK4a, and 1.8 (95% CI: 1.2-2.7) for SERPINB5. In conclusion, high mRNA expression levels of TMEM45A, SERPINB5 and p16INK4a were associated with increased risk of CIN3+ in persistently HPV16-infected women. PMID:27508094

    Despite a paucity of evidence, uphill running has been touted as a sport-specific resistance-to-movement training tactic capable of enhancing metabolic, muscular, and neuromuscular processes in distance runners in ways similar to previously established resistance-to-movement training methods, such as heavy and/or explosive strength training and plyometric training. Therefore, the purpose of this investigation included documenting the effects of incline and level-grade interval treadmill training on indices of running economy (RE) (i.e., oxygen consumption [VO2] and blood lactate [BLa] responses of submaximal running) and muscle power. Thirty-two well-trained distance runners (age, 27.4 ± 3.8 years; body mass, 64.8 ± 8.9 kg; height, 173.6 ± 6.4 cm; and VO2max, 60.9 ± 8.5 ml·min(-1)·kg(-1)) received assignment to an uphill (GHill = 12), level-grade (GFlat = 12), or control (GCon = 8) group. GHill and GFlat completed 12 interval and 12 continuous run sessions over 6 weeks, whereas GCon maintained their normal training. Dependent variables measured before and after training were VO2 and BLa at 2 separate velocities associated with lactate threshold (VLT) (VO2-60% and VO2-80%; and BLa-60% and BLa-80%, respectively); percentage of VO2max at lactate threshold (%VO2max at VLT); muscle power as assessed through a horizontal 5-jump test (5Jmax); and isokinetic knee extension and flexion at 3 angular velocities (90, 180, and 300°·s(-1)). Statistical significance was set to p ≤ 0.05. All groups significantly improved 5Jmax, VO2-60%, VO2-80%, BLa-60%, and BLa-80%. Additionally, GHill and GFlat significantly improved %VO2max at VLT. Other indices of RE and muscle power did not improve. We conclude incline treadmill training effective for improving the components of RE, but insufficient as a resistance-to-movement exercise for enhancing muscle power output. PMID:24172721

  12. Oral vaccination of calves with an aromatic-dependent Salmonella dublin (O9,12) hybrid expressing O4,12 protects against S. dublin (O9,12) but not against Salmonella typhimurium (O4,5,12).

    Three groups of six calves each, 5 to 7 weeks old, were orally vaccinated with the live aromatic-dependent delta aroA Salmonella dublin (O9,12) hybrid strain SL7103 with the O4,12-specifying rfb gene cluster from Salmonella typhimurium. SL7103 was given in three weekly doses, increasing from 2 x 10(9) to 1 x 10(11) bacteria per ml, was well tolerated, and caused mild, short-term temperature increases which diminished with each immunization. The strain was shed for up to 1 week. Strain SL7103 elicited significant (P < 0.001) and equal anti-S. dublin and -S. typhimurium lipopolysaccharide serum antibody responses and skin delayed-type hypersensitivity immune responses. Six vaccinated calves orally challenged with 10(10) CFU (equivalent to 1,000 50% lethal doses) of the virulent parent strain S. dublin SVA47 were protected and experienced only transient fever and mild mucoid diarrhea. However, six vaccinated calves orally challenged with 3 x 10(9) CFU and another six challenged with 3 x 10(8) CFU (equivalent to 1,000 50% lethal doses) of the virulent S. typhimurium SVA44 became bacteremic with a profuse hemorrhagic diarrhea and had to be sacrificed within 2 to 7 days. The results suggest that the S. typhimurium antilipopolysaccharide immunity was insufficient to provide a solid protective efficacy against oral S. typhimurium infection. The immunohistopathological examination revealed that S. typhimurium SVA44 could be found in all layers of the intestinal mucosa and the lymphatic tissues of the Peyer's patches. In contrast, S. dublin SVA47 was found predominantly in the columnar enterocytes of the jejunum and ileum and the follicle-associated epithelium over the Peyer's patches. In addition, SVA47 was found in the glandular tissues of the duodenal and tonsillar areas and in the lungs. This suggests that the S. typhimurium and S. dublin strains have different virulence traits determining their tissue localization and dissemination. Images PMID:7681042

    A study was conducted to assess the nutritive value of Enterolobium cyclocarpum seeds as supplementary feed for ruminant animals during the dry season when grasses are either not available or of low quality. Matured fruits of E. cyclocarpum were collected, toasted, peeled and then used for the trial. Thirty two West African Dwarf (WAD) sheep aged between 12 +/- 2 months with an average body weight of 10 +/- 2 kg were used in assessing the nutritive value of graded levels of toasted Enterolobium cyclocarpum seed in a concentrate diets as supplement to Panicum maximum basal diet. The percent compositions of the experimental diets were toasted E. cyclocarpum seeds at various levels of inclusion (0, 10, 20 and 30%) for diets 1, 2, 3 and 4. respectively. The diets (1-4) were consecutively fed to each animal at 50 g kg(-1) b.wt. for 12 weeks in a completely randomized design. Parameters taken were weekly body weights, daily feed intake, nutrient utilization and nitrogen balance status for each animal. Diet 2 had the highest significant (p < 0.05) nutrients intake being 871.88, 137.13, 147.59, 33.26 and 69.86 g day(-1) for DM, CP, CF, EE and ASH respectively. The Dry Matter Digestibility (DMD) coefficients decreased significantly (p < 0.05) with increased inclusion levels of toasted E. cyclocarpum seeds supplementation. Sheep fed diet 4 had the lowest feed conversion ratio (8.61) and the highest daily average gain of 58.93 g. However the animals fed Diet 2 had the highest nitrogen retension and converted their feed to flesh. PMID:24506053

    Psychrophilic bacterial strains were isolated from alpine glaciers in Switzerland and characterized taxonomically. On the basis of phylogenetic analysis of partial 16S rRNA and rpoB genes, three of those strains, strain 79 ( = CCOS 247), strain 4/58 ( = CCOS 250) and strain 4/56 ( = CCOS 258) clustered together with strain Cr9-12T and separately from the type strains Glaciimonas immobilis Cr9-30T and Glaciimonas singularis LMG 27070T. Strain Cr9-12T has been previously described as a strain of G. immobilis. The three newly isolated strains were compared phenotypically with strain Cr9-12T and with the type strains of the species G. immobilis and G. singularis. Cr9-12T and the three novel strains from an alpine glacier in Switzerland were Gram-stain-negative, non-motile, rod-shaped and psychrophilic and showed good growth throughout a temperature range of 1-20 °C and characteristically oxidized d-mannitol, l-fucose and bromosuccinic acid. The predominant cellular fatty acids of strain Cr9-12T and the three novel strains were summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH), C16 : 0 and C18 : 1ω7c. The respiratory quinone of these strains was ubiquinone 8 (UQ-8). The genomic DNA G+C content of Cr9-12T was 49.2 mol%. The combined data from phenotypic, phylogenetic and DNA-DNA relatedness studies strongly support the reclassification of strain Cr9-12T as representing a novel species. This strain and the isolates 79 ( = CCOS 247), 4/58 ( = CCOS 250) and 4/56 ( = CCOS 258) are representatives of a novel species of the genus Glaciimonas, for which the name Glaciimonas alpina sp. nov. is proposed. The type strain of Glaciimonas alpina is Cr9-12T ( = CCOS 761T = DSM 22814T). PMID:26184665

    Using the ten-year (2000-2009) DA quality Terra MODIS and MISR aerosol products, as well as 7 years of Aqua MODIS, we studied both regional and global aerosol trends over oceans. This included both natural and data assimilation grade versions of the products. Contrary to some of the previous studies that showed a decreasing trend in aerosol optical depth (AOD) over global oceans, after correcting for what appears to be aerosol signal drift from the radiometric calibration of both MODIS instruments, we found MODIS and MISR agreed on a statistically negligible global trend of 0.0003/per year. Our study also suggests that AODs over the Indian Bay of Bengal, east coast of Asia, and Arabian Sea show statistically significant increasing trends of 0.07, 0.06, and 0.06 per ten years for MODIS, respectively. Similar increasing trends were found from MISR, but with less relative magnitude. These trends reflect respective increases in the optical intensity of aerosol events in each region: anthropogenic aerosols over the east coast of China and Indian Bay of Bengal; and a stronger influence from dust events over the Arabian Sea. Negative AOD trends are found off Central America, the east coast of North America, and the west coast of Africa. However, confidence levels are low in these regions, which indicate that longer periods of observation are necessary to be conclusive.

    We evaluated frontal brain activation during a mixed attentional/working memory task with graded levels of difficulty in a group of 19 healthy subjects, by means of time-domain functional near-infrared spectroscopy (fNIRS). Brain activation was assessed, and load-related oxy- and deoxy-hemoglobin changes were studied. Generalized linear model (GLM) was applied to the data to explore the metabolic processes occurring during the mental effort and, possibly, their involvement in short-term memorization. GLM was applied to the data twice: for modeling the task as a whole and for specifically investigating brain activation at each cognitive load. This twofold employment of GLM allowed (1) the extraction and isolation of different information from the same signals, obtained through the modeling of different cognitive categories (sustained attention and working memory), and (2) the evaluation of model fitness, by inspection and comparison of residuals (i.e., unmodeled part of the signal) obtained in the two different cases. Results attest to the presence of a persistent attentional-related metabolic activity, superimposed to a task-related mnemonic contribution. Some hemispherical differences have also been highlighted frontally: deoxy-hemoglobin changes manifested a strong right lateralization, whereas modifications in oxy- and total hemoglobin showed a medial localization. The present work successfully explored the capability of fNIRS to detect the two neurophysiological categories under investigation and distinguish their activation patterns.

    Corms such as wild cocoyam [Colocasia esculenta] have potential to replace maize as a cheaper energy source in poultry rations. A feeding trial was conducted to evaluate the effects of graded levels of fermented wild cocoyam [Colocasia esculenta (L.) Schott] corm (FWCC), as substitutes for maize in the diets of broilers at the starter phase. One hundred and twenty unsexed day-old Hybro broiler chicks were randomly distributed to four dietary treatments in a Completely Randomized Design (CRD). There were 3 replicates per dietary treatment with 10 birds per replicate. Diet 1 without FWCC served as the control. Diets 2, 3 and 4 contained 10, 20 and 30% FWCC. Each of the diets represented a treatment. The experimental diets and clean drinking water were supplied ad libitum for 4 weeks (28 days) representing the starter phase of the broiler production. Result of the performance revealed significant (p<0.05) differences in feed intake, weight gain and feed conversion ratio. The economic analysis also showed that cost (Naira58.52) of a kilogram feed was highest (p<0.05) for the control and least (Naira53.10) for 30% FWCC. The least cost (Naira101.24) of feed per kilogram weight gain (p<0.05) was obtained for birds fed 30% FWCC compared to (Naira105.53) for the control. It was concluded that maize can economically be substituted with 30% FWCC in broiler starter diets. PMID:26031004

    One hundred fifty Anak and 120 Nigerian heavy local ecotype (NHLE) chickens were used to study the effects of feeding graded levels of mango seed kernel meal (MKM) replacing maize diet on growth traits and haematological parameters. A 2 × 5 factorial arrangement was employed: two breeds and five diets. The birds were randomly allocated to five finisher diets formulated such that MKM replaced maize at 0, 10, 20, 30 and 40% (T1, T2, T3, T4 and T5) inclusion levels, respectively. The effect of breed and dietary treatments on growth performance and blood characteristics were determined. The results showed a significant (P < 0.05) breed effect on body weight and gain, shank length, thigh length, body width and body length. The growth traits of Anak breed were found to be superior to NHLE chickens. Within treatments, chicks on T1, T2 and T3, grew heavier than those on T4 and T5. However, feed intake, feed conversion ratio (FCR) and haematological indices (RBC, Hb, MCV, MCH and MCHC count) were not significant (P > 0.05) when the breeds and treatments were compared. It was concluded that inclusion of dietary MKM below 30% could replace maize in the diets of Anak and NHLE growing chickens without adverse effect on growth performance and blood constituents. This work suggests that genetic differences exist in growth traits of these breeds of chickens. This advantage could be useful in breed improvement programmes and better feeding managements of the NHLE and Anak chickens. PMID:25939914

    BACKGROUND: Predictive marker of bevacizumab activity is an unmet medical need. We evaluated predictive value of selected circulating prebiomarkers involved in neoangiogenesis and invasion on patient outcome in recurrent high grade glioma (HGG) treated with bevacizumab. METHODS: A set of eleven prebiomakers of interest (VEGF, VEGF-R2, bFGF, SDF1, PlGF, uPA, PAI1, MMP2, MMP7, MMP9, and adrenomedulline) were analyzed in plasma, using ELISA, at baseline and 2 weeks apart from bevacizumab initiation in a prospective cohort of 26 patients (Cohort1). Correlations were validated in a separate retrospective cohort (Cohort2;n = 50) and tested in cohort patients treated with cytotoxic agents without bevacizumab (Cohort3;n = 34). Dosages were correlated to objective response (OR), Progression-free survival (PFS), and overall survival (OS). In cohort 1, multiple time points were performed up to progression. Additionally MMP2 and MMP9 plasma levels were analyzed in patients with newly diagnosed GB, after surgery. Finally, MMP2 and 9 RNA were assessed in tumor tissue of a separated group of paired newly diagnosed and recurrent GB (n = 29). RESULTS: In cohort1, high MMP2 baseline level was associated to a probability of OR of 83.3% versus 15.4% in case of low MMP2 level (p = 0.001). In multivariate analysis, baseline level of MMP2 correlated with PFS (hazard-ratio(HR), 3.92; 95% confidence-interval(CI):1.46-10.52; p = 0.007) and OS (HR, 4.62; 95%CI 1.58-13.53; p = 0.005), as decrease of VEGF (p = 0.038 for PFS and p = 0.013 for OS) and MMP9 (p = 0.016 for PFS and p= 0.025 for OS). In cohort2, MMP2, but not MMP9, confirmed its predictive significance. In cohort3, no association was found between MMP2, MMP9 and outcome. In cohort 1, significant changes in MMP2 and MMP9 plasma levels were observed during treatment. MMP2 increased after Bev initiation (p = 0.002), and decreased at progression (p = 0.002) while MMP9 initially decreased (p = 0.007) then increased at progression (p = 0

  10. Efficacy of changing physics misconceptions held by ninth grade students at varying developmental levels through teacher addition of a prediction phase to the learning cycle

    NASA Astrophysics Data System (ADS)

    Oglesby, Michael L.

    This study examines the efficacy in correcting student misconceptions about science concepts by using the pedagogical method of asking students to make a prediction in science laboratory lessons for students within pre-formal, transitional, or formal stages of cognitive development. The subjects were students (n = 235) enrolled in ninth grade physical science classes (n=15) in one high school of an urban profile school district. The four freshmen physical science teachers who were part of the study routinely taught the concepts in the study as a part of the normal curriculum during the time of the school year in which the research was conducted. Classrooms representing approximately half of the students were presented with a prediction phase at the start of each of ten learning cycle lesson. The other classrooms were not presented with a prediction phase. Students were pre and post tested using a 40 question instrument based on the Force Concept Inventory augmented with questions on the concepts taught during the period of the study. Students were also tested using the Test of Scientific Reasoning to determine their cognitive developmental level. Results showed 182 of the students to be cognitively pre-formal, 50 to be transitional, and only 3 to be cognitively formal. There were significantly higher gains (p < .05) for the formal group over the transitional group and for the transitional group over the Pre-formal group. However, there were not significantly higher gains (p > .05) for the total students having a prediction phase compared to those not having a prediction phase. Neither were there significant gains (p > .05) within the pre-formal group or within the transitional group. There were too few students within the formal group for meaningful results.

    Background Mammary tumours are the most common malignancy diagnosed in female dogs and a significant cause of mortality and morbidity in this species. Carbohydrate antigen (CA) 15–3 is a mucinous glycoprotein aberrantly over-expressed in human mammary neoplasms and one of the most widely used serum tumour markers in women with breast cancer. The aim of this study was to investigate the antigenic analogies of human and canine CA 15–3 and to assess its expression in canine mammary cancer tissues and cell lines. Immunohistochemical expression of CA 15–3 was evaluated in 7 canine mammary cancer cell lines and 50 malignant mammary tumours. As a positive control, the human breast carcinoma cell line MCF7 and tissue were used. To assess CA 15–3 staining, a semi-quantitative method was applied. To confirm the specificity and cross-reactivity of an anti-human CA 15–3 antibody to canine tissues, an immunoblot analysis was performed. We also investigated serum CA 15–3 activity to establish whether its expression could be assigned to several tumour characteristics to evaluate its potential use as a serum tumour marker in the canine mammary oncology field. Results Immunocytochemical analysis revealed CA 15–3 expression in all examined canine mammary cancer cell lines, whereas its expression was confirmed by immunoblot only in the most invasive cells (CMT-W1, CMT-W1M, CMT-W2 and CMT-W2M). In the tissue, an immunohistochemical staining pattern was observed in 34 (68%) of the malignant tumours. A high statistical correlation (p = 0.0019) between serum CA 15–3 levels and the degree of tumour proliferation and differentiation was shown, which indicates that the values of this serum marker increase as the tumour stage progresses. Conclusions The results of this study reveal that CA 15–3 is expressed in both canine mammary tumour cell lines and tissues and that serum levels significantly correlate with the histological grade of the malignancy.

    The human safety aspects of seafood production require the expansion of vital knowledge of both nutrients and possible contaminants along the entire production chain. Thus, production of safer seafood can be achieved by using feed materials that are low in contaminants, while maintaining balanced nutrition, in order to secure optimal fish and consumer health. Our understanding of primary responses of fish health and production related diseases, as well as biological processes that influence carry-over and lowering of contaminants in farmed fish, will contribute to a sustainable production of safer seafood products. Therefore, we have studied the liver deposition and toxicological effects in salmon fed graded levels of BHT during a 12-week feeding followed by a 2-week depuration period using chemical, molecular, and catalytic assays. In general, our data showed that BHT was significantly retained in the liver and selectively modulated toxicological responses in the xenobiotic biotransformation pathways during the feeding period. Specifically, BHT produced consistent dose- and time-specific gene expression patterns for AhR2alpha, AhR2beta, CYP1A1, CYP3A, UGT1, and GSTpi. The effect of BHT on the gene expression of biotransformation enzyme did not parallel enzyme activity levels, suggesting a possible inhibition by parent BHT or its metabolites. As a safety precaution, the production of farmed Atlantic salmon in Norway requires a mandatory 2-week depuration period prior to slaughtering and market delivery to ensure the elimination of veterinary medicaments, additives, and other undesirable components. Comparison of feeding and depuration periods showed that BHT was highly retained in fish liver, as only 8-13% of fed BHT was eliminated during the 2-week depuration period. This is just a part of the total concentration in the whole fish, since BHT may have been distributed and accumulated in other organs. Since BHT or its metabolites putatively inhibited

    Grade inflation threatens the integrity of college grades as indicators of academic achievement. In this study, we contribute to the literature on grade inflation by providing the first estimate of the size of grade increases at the student level between the mid-1990s and mid-2000s. By controlling for student characteristics and course-taking…

  18. Retention in Grade: Lethal Lessons?

    ERIC Educational Resources Information Center

    Sherwood, Charles

    Despite a growing trend toward retention in grade of low-achieving students and apparent public support for the practice, many educators and psychologists disagree with the perception that flunking is an appropriate response to poor academic performance. Research reported in the past two decades indicates that grade-level retention produces little…
