Journal of Clinical Oncology 34, no 26 (10 septembre 2016) : 3166–74. http://dx.doi.org/10.1200/jco.2016.67.6346.
Texte intégralRésumé :
Purpose We evaluated the pharmacokinetics (PKs), pharmacodynamics, safety, and efficacy of selinexor, an oral selective inhibitor of nuclear export compound, in patients with advanced soft tissue or bone sarcoma with progressive disease. Patients and Methods Fifty-four patients were treated with oral selinexor twice per week (on days 1 and 3) at one of three doses (30 mg/m2, 50 mg/m2, or flat dose of 60 mg) either continuously or on a schedule of 3 weeks on, 1 week off. PK analysis was performed under fasting and fed states (low v high fat content) and using various formulations of selinexor (tablet, capsule, or suspension). Tumor biopsies before and during treatment were evaluated for pharmacodynamic changes. Results The most commonly reported drug-related adverse events (grade 1 or 2) were nausea, vomiting, anorexia, and fatigue, which were well managed with supportive care. Commonly reported grade 3 or 4 toxicities were fatigue, thrombocytopenia, anemia, lymphopenia, and leukopenia. Selinexor was significantly better tolerated when administered as a flat dose on an intermittent schedule. PK analysis of selinexor revealed a clinically insignificant increase (approximately 15% to 20%) in drug exposure when taken with food. Immunohistochemical analysis of paired tumor biopsies revealed increased nuclear accumulation of tumor suppressor proteins, decreased cell proliferation, increased apoptosis, and stromal deposition. Of the 52 patients evaluable for response, none experienced an objective response by RECIST (version 1.1); however, 17 (33%) showed durable (≥ 4 months) stable disease, including seven (47%) of 15 evaluable patients with dedifferentiated liposarcoma. Conclusion Selinexor was well tolerated at a 60-mg flat dose on a 3-weeks-on, 1-week-off schedule. There was no clinically meaningful impact of food on PKs. Preliminary evidence of anticancer activity in sarcoma was demonstrated.

Texte intégralRésumé :
The objective of the paper is to determine types of code-mixing and code-switching made by teachers and students in EFL cross cultural communication class and to identify reasons for the emergence of code-switching and mixing in the classroom. The data was obtained through observation and in-depth interviews of the second year students of undergraduate program of English in Tarbiyah Faculty, IAIN IB Padang. The finding showed that tag-switching, intra-sentential, inter-sentential, and intra-word were commonly used by EFL teachers and students in classroom. It was also found that the teachers used code-mixing and switching in the process of clarifying certain issues to make them more comprehensible to students. Teachers also do these kinds of switching during their attempt to promote relationship with students, to switch the topic, and to persuade or motivate students to be more engaged in learning English. Meanwhile, the students mix and switch their language to overcome their lack of knowledge of English. It is expected that this study provided empirical evidence to advise on their optimal uses in EFL teaching of State Institute for Islamic Studies.Copyright © 2014 by Al-Ta'lim All right reserved

Texte intégralRésumé :
Proper management of agricultural disease is important to ensure sustainable food security. Staple food crops like rice, wheat, cereals, and other cash crops hold great export value for countries. Ensuring proper supply is critical; hence any biotic or abiotic factors contributing to the shortfall in yield of these crops should be alleviated. Rhizoctonia solani is a major biotic factor that results in yield losses in many agriculturally important crops. This paper focuses on genome informatics of our Malaysian Draft R. solani AG1-IA, and the comparative genomics (inter- and intra- AG) with four AGs including China AG1-IA (AG1-IA_KB317705.1), AG1-IB, AG3, and AG8. The genomic content of repeat elements, transposable elements (TEs), syntenic genomic blocks, functions of protein-coding genes as well as core orthologous genic information that underlies R. solani’s pathogenicity strategy were investigated. Our analyses show that all studied AGs have low content and varying profiles of TEs. All AGs were dominant for Class I TE, much like other basidiomycete pathogens. All AGs demonstrate dominance in Glycoside Hydrolase protein-coding gene assignments suggesting its importance in infiltration and infection of host. Our profiling also provides a basis for further investigation on lack of correlation observed between number of pathogenicity and enzyme-related genes with host range. Despite being grouped within the same AG with China AG1-IA, our Draft AG1-IA exhibits differences in terms of protein-coding gene proportions and classifications. This implies that strains from similar AG do not necessarily have to retain similar proportions and classification of TE but must have the necessary arsenal to enable successful infiltration and colonization of host. In a larger perspective, all the studied AGs essentially share core genes that are generally involved in adhesion, penetration, and host colonization. However, the different infiltration strategies will depend on the level of host resilience where this is clearly exhibited by the gene sets encoded for the process of infiltration, infection, and protection from host.

Journal of Bacteriology 183, no 24 (15 décembre 2001) : 7260–72. http://dx.doi.org/10.1128/jb.183.24.7260-7272.2001.
Texte intégralRésumé :
ABSTRACT Staphylococcus aureus is a gram-positive facultative aerobe that can grow in the absence of oxygen by fermentation or by using an alternative electron acceptor. To investigate the mechanism by which S. aureus is able to adapt to changes in oxygen concentration, we analyzed the transcriptional regulation of genes that encode the aerobic class Ib and anaerobic class III ribonucleotide reductase (RNR) systems that are responsible for the synthesis of deoxyribonucleotides needed for DNA synthesis. The S. aureus class Ib RNR nrdIEF and class III RNRnrdDG genes and their regulatory regions were cloned and sequenced. Inactivation of the nrdDG genes showed that the class III RNR is essential for anaerobic growth. Inhibition of aerobic growth by hydroxyurea showed that the class Ib RNR is an oxygen-dependent enzyme. Northern blot analysis and primer extension analysis demonstrated that transcription of class IIInrdDG genes is regulated by oxygen concentration and was at least 10-fold higher under anaerobic than under aerobic conditions. In contrast, no significant effect of oxygen concentration was found on the transcription of class Ib nrdIEF genes. Disruption or deletion of S. aureus nrdDG genes caused up to a fivefold increase in nrdDG and nrdIEFtranscription under anaerobic conditions but not under aerobic conditions. Similarly, hydroxyurea, an inhibitor of the class I RNRs, resulted in increased transcription of class Ib and class III RNR genes under aerobic conditions. These findings establish that transcription of class Ib and class III RNR genes is upregulated under conditions that cause the depletion of deoxyribonucleotide. Promoter analysis of class Ib and class III RNR operons identified several inverted-repeat elements that may account for the transcriptional response of thenrdIEF and nrdDG genes to oxygen.

Texte intégralRésumé :
ABSTRACT Extraintestinal pathogenic Escherichia coli (ExPEC) include several serotypes that have been associated with colibacillosis in poultry and with urinary tract infections (UTIs) and newborn meningitis in humans. In this study, 57 antimicrobial-resistant E. coli from apparently healthy broiler chickens were characterized for their health and safety risks. These isolates belonged to 12 serotypes, and isolates of the same serotype were clonal based on single nucleotide variant analysis. Most of the isolates harbored plasmids; IncC and IncFIA were frequently detected. The majority of the resistant isolates harbored plasmid-mediated resistance genes, including aph(3″)-Ib, aph(6)-Id, blaCMY-2, floR, sul1, sul2, tet(A), and tet(B), in agreement with their resistant phenotypes. The class 1 integron was detected in all E. coli serotypes except O124:H25 and O7:H6. Of the 57 broiler E. coli isolates, 27 were avian pathogenic, among which 18 were also uropathogenic E. coli and the remainder were other ExPEC. The two isolates of serotype O161:H4 (ST117) were genetically related to the control avian pathogenic strains and a clinical isolate associated with UTIs. A strain of serotype O159:H45 (ST101) also was closely related to a UTI isolate. The detected virulence factors included adhesins, invasins, siderophores, type III secretion systems, and toxins in combination with other virulence determinants. A broiler isolate of serotype O7:H18 (ST38) carried the ibeA gene encoding a protein involved in invasion of brain endothelium on a 102-kbp genetic island. This isolate moderately adhered and invaded Caco-2 cells and induced mortality (42.5%) in a day-old-chick infection model. The results of this study suggest that multiple antimicrobial-resistant E. coli isolates recovered from apparent healthy broilers can be pathogenic and act as reservoirs for antimicrobial resistance genes, highlighting the necessity of their assessment in a “One-Heath” context.

Texte intégralRésumé :
TPS762 Background: Overcoming resistance to chemotherapy and immune checkpoint inhibitors remains an unmet need for PDAC. In this context, TGF-β plays a key role in PDAC by promoting the activation of fibroblasts and extracellular matrix deposition, facilitating epithelial-to-mesenchymal transition, immune evasion, and resistance to chemotherapy. Combination of FOLFIRINOX with losartan, an indirect TGF-β inhibitor with antifibrotic properties, has shown an increased R0 resection rate in pts with BR/LA PDAC, providing the rationale to explore the combination of other TGF-β targeting agents with FOLFIRINOX in the neoadjuvant setting (PMID: 34884782; PMID: 31145418). NIS793 is a first-in-class monoclonal antibody that directly binds TGF-β and reduces intratumoral fibrosis in preclinical models (PMID: 33298926). NIS793 also has an acceptable safety profile and preliminary clinical activity. This study investigates whether NIS793 modulation of the tumor fibrotic network improves clinical outcomes of FOLFIRINOX neoadjuvant therapy in BR/LA PDAC. Our aim is to demonstrate how TGF-β inhibition and stroma remodeling contribute to clinical outcomes. Methods: This is a single institution, open label, 2-part, 2-arm, non-comparator, Phase Ib study (NCT05417386) of FOLFIRINOX + NIS793 as neoadjuvant therapy for pts with untreated BR/LA PDAC. Eligible pts are adults with measurable disease, adequate organ and bone marrow function, and ECOG PS ≤1. In Part 1 (safety run-in), 6-18 pts with histologically confirmed untreated metastatic PDAC receive FOLFIRINOX + NIS793 at different dose levels. Dose escalation is primarily guided by the number of dose-limiting toxicities. Primary objectives are assessing safety, defining the recommended Phase II dose (RP2D), and providing initial evidence of clinical benefit of the combination. In Part 2, pts with untreated BR/LA PDAC are randomized 4:1 and stratified by BR vs LA. Pts in Arm 1 (n=5) receive 8 cycles of FOLFIRINOX followed by chemoradiation therapy (CRT) and surgery. Pts in Arm 2 (n=23) receive 8 cycles of FOLFIRINOX + NIS793 at RP2D followed by CRT + NIS793, surgery, and 12 cycles of adjuvant NIS793. The primary endpoint is R0 resection rate. Secondary endpoints are disease-free survival, progression-free survival, overall survival, and pathologic complete response. The effect of neoadjuvant therapy will be assessed by ferumoxytol-MRI, circulating cell-free DNA dynamics analysis, single-cell RNA sequencing, immunohistochemistry, and digital spatial analysis. Together, these correlative analyses may enable development of a mechanistic model for TGF-β inhibition in PDAC. This study is ongoing. The first pt was treated on Aug 2, 2022. Clinical trial information: NCT05417386 .

Texte intégralRésumé :
ABSTRACT Twenty Acinetobacter baumannii strains resistant to various antibiotics were analyzed for integron content and sequences of the amplification products. Sixteen clinical isolates had a class 1 integron, 2 contained an additional class 1 or class 2 integron, but no class 3 integron was detected. Thirteen strains had integrons with a single cassette: aac(3)-Ia (9 strains), ant(2")-Ia (2 strains), or aac(6′)-Ib (2 strains); 1 hadaac(6′)-Ib and oxa20cassettes and an unknown gene; and 1 had an integron containingant(2")-Ia and an oxa3cassette truncated by IS6100. The remaining strains harbored class 1 integrons with gene cassettes previously found inEnterobacteriaceae. One integron had a hybrid structure composed of intI2 and the 3′ conserved segment of class 1 integrons. These data indicate that integrons play a major role in multidrug resistance in Acinetobacter.

Texte intégralRésumé :
Abstract The BALB/c mouse has at least 29 class I genes encoded in the Qa, Tla, and Hmt (histocompatibility dependent on a maternally transmitted factor) regions of the MHC. The pattern of expression of these class Ib MHC genes is not well characterized, although some of their products such as the serologically detectable Qa-2 and TL Ag are expressed mainly in lymphoid and hematopoietic tissues. In this study, the expression pattern of BALB/c class I genes has been analyzed in adult bone marrow and fetal liver. cDNA libraries were synthesized from these tissues, and isolated class I cDNA clones were characterized by hybridization with oligonucleotide probes and by nucleotide sequence analysis. Of the 29 total class Ib genes, transcripts of five including Q6d, Q7d, T9c, T10c, and the 37 gene were isolated from the bone marrow cDNA library. Four of these can encode proteins; the sequence of the T10c gene demonstrates it is most likely a pseudogene. A non-overlapping set of three class Ib cDNA clones was obtained from the fetal liver, including T13c, the Thy 19.4 gene, and a previously uncharacterized class I gene provisionally designated as FL 57.2. Although the majority of H-2Dd cDNA clones that were analyzed lack introns, many of the class Ib cDNA clones contain intron sequences. This suggests that the expression of some of these genes may be regulated at the level of RNA splicing. The T13c gene encodes the thymus leukemia Ag in BALB/c mice. We have confirmed that the T13c gene is expressed in fetal liver by flow cytometric analysis of cells stained with anti-TL mAb.

Texte intégralRésumé :
Abstract The heat shock proteins (hsps) hsp70 are highly conserved molecular chaperones that elicit potent T cell responses against the antigens (Ags) they chaperone in both mammals and Xenopus. We have shown that frogs immunized with hsp70 generate CD8 T cell responses against the Xenopus thymic tumor 15/0 that expresses several nonclassical MHC class Ib genes, but not classical MHC class Ia. Therefore, we hypothesized that hsp70 can prime class Ib-mediated anti-tumor unconventional CD8 T cells in an Ag-dependent manner. To test this, we produced Xenopus recombinant tagged hsp70 proteins (both the cognate hsc73 and the inducible hsp72) from stable 15/0 tumor transfectants. Antigenic peptides can be easily removed from both hsps by ATP treatment. We used a cross-presentation assay to adoptively transfer hsp-pulsed antigen presenting cells and showed that both hsp72 and hsc73-Ag complexes, but not ATP treated Ag-negative hsp70s, elicit class Ib-mediated CD8 T cells responses resulting in protection from 15/0 tumor challenge. From expression studies, we further postulate that these responses involve one or a few class Ib gene products among which XNC10 is the prime candidate due to its lymphoid tissue distribution. To further elucidate the role of class Ib molecules in anti-tumor immunity, we developed a reverse genetic approach combining transgenesis and siRNA technology and obtained F1 Xenopus clones with silenced expression of class Ib in vivo that will be used for further analysis.

ABSTRACT
The research deals with the photographic image in its exclusively documental aspect. However, in order to do that, it comments some photography’s technical and conceptual issues. This approach encompasses activities that are inserted in the practical aspect of Science Information, and it includes the DAM process of digital image organization. The main aspect considered in the research is the thematization of photographic image which is responsible, in the first place, for the determination of thematic discourses and for the delimitation and direction of these discourses due to characteristics of image banks where the photos will be stored and, secondly, for the gathering of totally different photos but that have some sort of discourse that they might have in common. As it deals with thematizing a kind of image (the photographic one) offers a general view in itself, showing its importance as a mean of interaction between men and the world and its meanings as communication of ideas, knowledge and doctrines, from pre history to these days. It also briefly shows the image thematization process indicating how men used to delimit and direct the imaging discourses according to their conveniences and political and/or religious interests. It shows some basic topics that guide the research such as a very brief photography history and concepts of: reference, photographic reality, polysemy, photographic denotation, Dubois´ (2007), DE´s, SOBRE´s and Shatford´s (1994) theories and so on. It presents the concept of photographic thematization and indicates the reason of thematizing photographies. It compares thematization to index showing that thematization is a technique prior to index in the organization process of photographic image. It shows that thematization is influenced by many factors such as photography’s technical and visual qualities (based on Gestalt’s form principles), possible functions that photography might have, cognition and analysts´ and users´ mental image and, mainly, image bank characteristics. It presents a practical exercise with 22 photographies that go through a whole thematization process, including descriptive analysis (based on the so called information points), interpretative analysis and the determination, delimitation and direction of thematic discourses. The last chapter weaves some final considerations demonstrating the results reached by the research.

Texte intégralRésumé :
How to motivate students effectively is a question teachers have asked for thousands ofyears. In my teaching program at Malmö University, a variety of teaching methods andapproaches, that also increase motivation, have come into focus. These include:teaching at the right level, using a variety of teaching methods, seeing every student,being enthusiastic about the material, using formative evaluation, connecting lessons tostudents’ everyday life, and adapting classes to students’ interests. The aim of this studyis to find out how secondary students in a social science program perceive teachingmethods and approaches aimed at increasing motivation, and determine which methodsthey perceive as most/least effective. The study used both qualitative and quantitativemethods. 23 upper-secondary students from a class at a school in southern Swedenwere interviewed in four focus groups, where participants were purposefully sampled.10 of these students were also asked to complete a questionnaire ranking the teachingmethods and approaches on a scale of 1-7 (where 1 was most effective at increasingmotivation and 7 least effective), and the mean values of these scores were used in theanalysis. A phenomenological approach and content analysis were used to code andanalyze the data. Students perceived all of the motivational methods to be effective, themost effective being teaching lessons at the right level, followed by using a variety ofteaching methods, with mean values of 1.9 and 3.2, respectively. Adapting lessons tostudents’ interests and connecting them to everyday life were the least effective, withmean values of 5.6 and 5.7, respectively. The categories of teachers having a positiveattitude towards the material and the students, and seeing every student, had the samemean value, 3.8, while formative evaluation had a mean value of 3.9. When trying tomotivate students, it would thus appear more effective to make sure that lessons aretaught at the right level and that teachers vary the lessons, than to adapt lessons tostudents’ interests or connect the material to everyday life. While this was a small studyand the findings cannot be generalized to school populations, they are of high interestfor the researcher.

Texte intégralRésumé :
Denna uppsats belyser några av förskoleklassens läromedel i matematikämnet. Vi har undersökt specifikt i vilken utsträckning leken tar plats i läromedel, samt vilket stöd läraren får att genomföra lek som kan bidra till elevernas begrepps och/eller resonemangsförmåga. Förskoleklassen har nyligen blivit obligatorisk och ska fungera som en bro mellan förskolan och skolan. Den förväntas ta över förskolans lekpedagogik samtidigt som den ska introducera skolans rutiner och undervisningsmetoder. Vi har använt innehållsanalys som metod för att undersöka läromedel både kvantitativt och kvalitativt. Studiens resultat visar att lek som bidrar till elevernas begrepps- och/eller resonemangsförmåga finns i lärarhandledningar. Det finns även olika typer av stöd för läraren att genomföra lekbaserad undervisning som bidrar till elevernas begrepps- och/eller resonemangsförmåga. Det kan bidra till att eleverna utvecklar och befäster sina kunskaper om matematiska begrepp och/eller resonemang via leken. Studien visar också att lek i läromedlets elevböcker i stort sett saknas. Vilket kan innebära att eleverna går miste om lek i matematikundervisningen om läraren väljer att endast använda elevboken.This master thesis focuses on mathematics textbooks for preschool class. We have studied to what extent play is found in the textbooks and what kind of the support for implementation is offered to the teacher. We have focused on play which can contribute to the pupils’ concept and/or reasoning ability. Preschool class is now a compulsory school form. Preschool class is a class between preschool and primary school and is expected to function as a bridge between these two. There are many expectations for preschool class: implementing preschool pedagogy while introducing the primary school’s routines and teaching methods. We have used content analysis as a method in this study. The method has been used in both a quantitative and a qualitative way. The results show that teacher guides offer play contributing to conceptual and/or reasoning. The results also show that the teacher gets support for implementing such play in the classroom. This offers opportunities for pupils to consolidate and develop their knowledge of mathematical concepts as well as their reasoning. Further, the study shows that play in the pupils’ textbook largely is lacking. If the teacher chooses to only use the pupil’s textbooks, the consequence can be that the pupils are missing out on play in mathematical education.

Texte intégralRésumé :
This work explores the multidimensional, ambiguous and temporal characteristics of tonality. The approach relies on interfacing pitch-spaces with time vs. time-scale descriptions. In this combined representation, the spatial and temporal hierarchies of tonality are evidenced simultaneously and in relation to each other. A visual exploration method is proposed for the analysis of tonal context in music works, using a simple model of tonal induction. The method is extended for the analysis of music based on tonal systems beyond the major-minor paradigm. Two perceptual studies are approached from this descriptive framework. The first study evidences the impact of time-scale in a simple mode of tonal induction, and analyses the mathematical artefacts introduced by evaluations in scaled spaces. In the second study, a model of contextual instability is proposed and discussed in relation to the modelling of tonal tension. The analysis and representation methods are then generalised, through a set-class theoretical domain.Esta tesis analiza la naturaleza ambigua, multidimensional y temporal de la tonalidad. El método propuesto parte de la conexión entre espacios tonales y descripciones en tiempo y escala temporal. Esta representación conjunta pone de manifiesto la relación entre las jerarquías espaciales y temporales de la tonalidad. Utilizando un modelo simple de inducción tonal, se propone un método de exploración visual del contexto tonal en obras musicales. Dos estudios perceptuales son abordados desde el entorno descriptivo propuesto. En el primer estudio, se pone en evidencia el impacto de la escala temporal como parámetro de un modelo simple de inducción tonal, y se analizan los artificios matemáticos introducidos por evaluaciones en espacios escalados dimensionalmente. En el segundo estudio se propone un modelo de inestabilidad contextual, y se analiza en relación al modelado de la tensión tonal. El método de análisis se generaliza, a través de una categorización contextual en set-classes.

Texte intégralRésumé :
Syftet med studien är att få en inblick i hur matematiska läroböcker, riktade till förskoleklass, kan bidra till utvecklingen av en problemlösningskompetens. Detta gjordes genom att undersöka omfattningen och placeringen av problemlösningsuppgifter i läroböcker riktade till förskoleklass. Med hjälp av ett tidigare beprövat ramverk kunde vi kategorisera uppgifter från sex olika läroböcker genom en kvantitativ innehållsanalys. Resultatet visade att problemlösningsuppgifter var underrepresenterade i alla läroböckerna och att högst procent problemlösningsuppgifter var placerade som en första deluppgift och minst procent som avslutande uppgifter. Vid de tillfällen där läroböckerna explicit markerat att det handlade om problemlösning var majoriteten av uppgifterna problemlösningsuppgifter. Samtliga läroböcker ansågs innehålla för låg andel problemlösningsuppgifter för att i tillräcklig mån kunna bidra till utvecklandet av en problemlösningskompetens. Placeringen av problemlösningsuppgifterna i läroböckerna var generellt positiv för att kunna bidra till ökat problemlösningskompetens. Att problemlösningsuppgifter dominerar där det beskrivs handla om problemlösning anses vara positivt, dock återfanns ändå 29,5% andra uppgifter, vilket kan skapa en skev bild av vad problemlösning är.The purpose of the study is to gain an insight into how mathematical textbooks, aimed for preschool class, can contribute to development of a problem-solving competence. This was done by examining the extent and location of problem-solving tasks in textbooks aimed for preschool class. Using a previously proven framework, we were able to categorize data from six different textbooks through a quantitative content analysis. The results showed that problem-solving tasks were underrepresented in all textbooks and that the highest percentage of problem-solving tasks was placed as a first sub-task and the lowest percentage as concluding tasks. At the times when the textbooks explicitly stated that it was a problem-solving task, the majority of the tasks were problem-solving tasks. All textbooks were considered to include too low a share of problem-solving tasks, for it to be able to contribute to the development of a problem-solving competence. The placement of the problem-solving tasks in the textbooks was generally positive, in the meaning that it enabled them to contribute to increased problem-solving competence. Problem-solving dominates where it is described to be a problem-solving task which is considered positive, however, 29.5% other tasks were still found, and that can create a skew picture of what problem-solving is.

Dissertação de Mestrado em Ciência PolíticaA dissertação tem como objeto de estudo a autodeterminação da classe política madeirense reivindicada durante os discursos proferidos nas sessões legislativas regionais, entre 2010-2017. A escolha deve-se ao facto de apesar a ligação entre o discurso da autodeterminação e a formação de novos Estados ser constante ao longo dos tempos, o seu estudo encontra-se pouco representado na literatura. Deste modo, o objetivo é identificar e explanar a posição e intenção da autodeterminação da classe política madeirense proferida durante os discursos parlamentares regionais durante e pós crise económico-financeira. A questão nuclear que norteia a investigação é: Com que intenção usou a classe política madeirense o discurso de autodeterminação durante os anos da Troika em Portugal? Para tal socorri à metodologia qualitativa e quantitativa, mais concretamente o método da análise de conteúdo e ao software MAXQDA. O principal outcome é o de que a classe política da RAM profere um discurso como símbolo de poder e como uma ferramenta de contestação contra o poder do Governo Central e que com o objetivo de obter financiamentos, através do discurso, ergue um movimento de autodeterminação acentuada e persuasivamente durante o período de crise financeira, acrescendo na era da Troika, enquanto que a partir do período pós-Troika as reivindicações tornam-se menos frequentes e menos agudas
The aim of this study was to explore the self-determination claims of the political class in Madeira during the speeches delivered in the regional legislative sessions between 2010-2017. This choice comes from the fact that, despite the link between the selfdetermination speech and the formation of new States being constant throughout the years, the study is not represented enough in literature. In this sense, the intent is to identify and explain the self-determination claimed by Madeira’s political class at the regional legislative sessions during and after the financial crisis. The nuclear question that guides this investigation is: What was the intention of the Madeira’s political class in using a self-determination speech through all of the troika years in Portugal? For this, I used a qualitative and quantitative methodology, more specifically the method of content analysis and the software MAXQDA. The main result is that the political class produces speeches as a symbol of power and as a tool of contesting against the power of the Central government. So, to get funding, through the speeches, a movement of strong and persuasive self-determination was upraised during the period of financial crisis, increasing in the era of the Troika, while from the PostTroika period the claims become less frequent and less critical

It is characterized by large areas of retinal pigment epithelium (RPE) atrophy that grow progressively, with concomitant loss of photoreceptors and choriocapillaris. Currently, there is no treatment for this disorder. Lipofuscin build-up within the RPE, which is identifiable by fundus autofluorescence (FAF) as areas of increased autofluorescence, has been linked to GA progression in some studies. Actually, the distribution of hyperautofluorescence on FAF identified some patterns (“phenotypes”), which have been associated with specific rates of disease growth. We conducted a prospective clinical study to simplify the complex classification of FAF patterns and to determine the role of increased FAF, a biomarker of lipofuscin, in the progression of GA.

Texte intégralRésumé :
Research has shown that there are gaps in knowledge between newly hired and experienced professionals and that some of these gaps are related to concepts, such as the concepts of object orientation. This problem, and the fact that most computer science majors want to work in the software industry, leads to questions regarding why these gaps exist and how students can be better prepared for their future careers. Against this background, this thesis addresses two theme-based perspectives that focus on students' views of concepts in Computer Science. The first theme-based perspective investigated the existence of potential Threshold Concepts in Computer Science. Such concepts should be troublesome, transformative, irreversible, and integrative. Qualitative methods have been mainly used and empirical data have been collected through semi-structured interviews, concept maps, and written stories. The results identified two Threshold Concepts, suggested several more, and then described the ways in which these concepts have transformed students. The second theme-based perspective took a phenomenographic approach to find the variation in how students understand concepts related to the software profession. Data were collected via semi-structured interviews. In one study the interviews were held in connection with role-playing where students took on the role of a newly hired programmer. The results show a variety of ways to experience the addressed phenomena in the student collective, ranging from superficial views that often have a practical nature to more sophisticated understandings that reflect a holistic approach, including a professional point of view. Educators can use the results to emphasize concepts that are important from students' perspectives. The phenomenographic outcome spaces can help teachers to reflect upon their own ways of seeing contrasted with student conceptions. I have indicated how variation theory can be applied to open more sophisticated ways of seeing, which in this context stresses the professional aspects to help students prepare for becoming professional software developers.

Texte intégralRésumé :
This chapter presents a commentary on John Sayles' film career. Sayles has long been referred to as America's leading independent filmmaker. More recently, he has been called both the grandfather and the godfather of American independent cinema. The press has also described Sayle's as a realist. Realism here means a particular kind of content, and that content is connected to a traditionally leftist position of support for workers. These are both aspects of Sayles' realism, but many of his films are neither gritty nor are focused on a particular class. The remainder of the chapter traces Sayles' path to filmmaking, where he began as writer of short stories and novels. It then turns to an analysis of his films, which include Liana (1983), Baby It's You (1983), The Brother from Another Planet (1984), Matewan (1987), Eight Men Out (1988), Lone Star (1996), Silver City (2004), and Honeydripper (2007).

Texte intégralRésumé :
AbstractThe notion of World Class Universities, and the use of rankings in general, has been an object of study for decades. Perhaps the first major critical work was Ellen Hazelkorn’s Rankings and the reshaping of higher education: The battle for world-class excellence (2011). Just as the influence of rankings shows no sign of abating, neither does the impetus to provide practical proposals for how to use them to advantage, or, alternatively, to examine the sources and effects of the practices involved. Recent interventions belonging to the first category are Downing and Ganotice’s World university rankings and the future of higher education (2017), while Stack’s Global university rankings and the mediatization of higher education (2016) and Hazelkorn’s Global rankings and the geopolitics of higher education: Understanding the influence and impact of rankingson higher education, policyand society (2016) are notable examples of the latter. The essays presented in the present volume are intended to contribute to our understanding of the phenomenon, its causes and consequences by filling three functions: (i) to provide an updated analysis of current trends in rankings and an examination of recent data regarding World Class University (WCU) initiatives relevant to the form and content of higher education; (ii) to study these especially with an eye to particular ramifications for work on the shop floor, that is to say, for university teachers and students; (iii) to investigate possible future courses and alternative trajectories.

Texte intégralRésumé :
AbstractApproaches for the collection and analysis of plastic debris in environmental matrices are rapidly evolving. Such plastics span a continuum of sizes, encompassing large (macro-), medium (micro-, typically defined as particles between 1 μm and 5 mm), and smaller (nano-) plastics. All are of environmental relevance. Particle sizes are dynamic. Large plastics may fragment over time, while smaller particles may agglomerate in the field. The diverse morphologies (fragment, fiber, sphere) and chemical compositions of microplastics further complicate their characterization. Fibers are of growing interest and present particular analytical challenges due to their narrow profiles. Compositional classes of emerging concern include tire wear, paint chips, semisynthetics (e.g., rayon), and bioplastics. Plastics commonly contain chemical additives and fillers, which may alter their toxicological potency, behavior (e.g., buoyancy), or detector response (e.g., yield fluorescence) during analysis. Field sampling methods often focus on >20 μm and even >300 μm sized particles and will thus not capture smaller microplastics (which may be most abundant and bioavailable). Analysis of a limited subgroup (selected polymer types, particle sizes, or shapes) of microplastics, while often operationally necessary, can result in an underestimation of actual sample content. These shortcomings complicate calls for toxicological studies of microplastics to be based on “environmentally relevant concentrations.” Sample matrices of interest include water (including wastewater, ice, snow), sediment (soil, dust, wastewater sludge), air, and biota. Properties of the environment, and of the particles themselves, may concentrate plastic debris in select zones (e.g., gyres, shorelines, polar ice, wastewater sludge). Sampling designs should consider such patchy distributions. Episodic releases due to weather and anthropogenic discharges should also be considered. While water grab samples and sieving are commonplace, novel techniques for microplastic isolation, such as continuous flow centrifugation, show promise. The abundance of nonplastic particulates (e.g., clay, detritus, biological material) in samples interferes with microplastic detection and characterization. Their removal is typically accomplished using a combination of gravity separation and oxidative digestion (including strong bases, peroxide, enzymes); unfortunately, aggressive treatments may damage more labile plastics. Microscope-based infrared or Raman detection is often applied to provide polymer chemistry and morphological data for individual microplastic particles. However, the sheer number of particles in many samples presents logistical hurdles. In response, instruments have been developed that employ detector arrays and rapid scanning lasers. The addition of dyes to stain particulates may facilitate spectroscopic detection of some polymer types. Most researchers provide microplastic data in the form of the abundances of polymer types within particle size, polymer, and morphology classes. Polymer mass data in samples remain rare but are essential to elucidating fate. Rather than characterizing individual particles in samples, solvent extraction (following initial sample prep, such as sediment size class sorting), combined with techniques such as thermoanalysis (e.g., pyrolysis), has been used to generate microplastic mass data. However, this may obviate the acquisition of individual particle morphology and compositional information. Alternatively, some techniques (e.g., electron and atomic force microscopy and matrix-assisted laser desorption mass spectrometry) are adept at providing highly detailed data on the size, morphology, composition, and surface chemistry of select particles. Ultimately, the analyst must select the approach best suited for their study goals. Robust quality control elements are also critical to evaluate the accuracy and precision of the sampling and analysis techniques. Further, improved efforts are required to assess and control possible sample contamination due to the ubiquitous distribution of microplastics, especially in indoor environments where samples are processed.

Texte intégralRésumé :
Chronic kidney disease has become a very prevalent problem worldwide and almost 10% of the population is suffering and millions of people are dying every year because of chronic kidney disease. Numerous machine learning and data mining techniques are applied by many researchers around the world to diagnose the presence of chronic kidney disease, so that the patients of chronic kidney disease may get benefited in terms of getting proper healthcare follow-up. In this chapter, Experiment 1 is conducted by implementing different five different classifiers on the original chronic kidney disease dataset. In Experiment 2, feature selection using feature importance method is used to reduce the chronic kidney disease dataset. A subset of 15 independent features and one target feature ‘class' is obtained. Again, the same steps are implemented but on the newly obtained reduced dataset. The results of both the Experiments 1 and 2 are compared, and it is observed that the accuracy of classifiers with feature selection is far better than the accuracy of classifiers without feature selection.

Computer Supported Collaborative Science (CSCS) is a teaching pedagogy that uses collaborative web-based resources to engage all learners in the collection, analysis, and interpretation of whole-class data sets, and is useful for helping secondary and college students learn to think like scientists and engineers. This chapter presents the justification for utilizing whole-class data analysis as an important aspect of the CSCS pedagogy and demonstrates how it aligns with the Next Generation Science Standards (NGSS). The chapter achieves this end in several ways. First, it reviews rationale outlined in the NGSS science and engineering practices for adapting 21st century technologies to teach students 21st century science inquiry skills. Second, it provides a brief overview of the basis for our pedagogical perspective for engaging learners in pooled data analysis and presents five principles of CSCS instruction. Third, we offer several real-world and research-based excerpts as illustrative examples indicating the value and merit of utilizing CSCS whole-class data analysis. Fourth, we postulate recommendations for improving the ways science, as well as other subject matter content areas, will need to be taught as the U.S. grapples with the role-out of new Common Core State Standards (CCSS) and NGSS. Taken together, these components of CSCS whole-class data analysis help constitute a pedagogical model for teaching that functionally shifts the focus of science teaching from cookbook data collection to pooled data analysis, resulting in deeper understanding.

Texte intégralRésumé :
Owing to the rising needs of English language for communication at a global level, experts have stressed the significance of teaching English supported by materials based on communicative language teaching (CLT) principles to facilitate the development of communicative competence. This study, therefore, aims to evaluate ESL teaching materials to check their suitability to develop learners' communicative competence. The study, for this purpose, employs content analysis approach for the analysis of text of English designed for class two in the light of a checklist devised on CLT principles. The results reveal that the content of the said textbook does not conform to the CLT principles. Therefore, it is not suitable to facilitate the development of communicative competence in the learners. The study suggests either to improve/revise the textbook or to replace it by another suitable one.

Texte intégralRésumé :
Science is traditionally considered one of the most complex and demanding subjects in school, yet can be one of the most inspiring experiences one has encountered in their academic life. Scientific knowledge can be applied to and explain everyday life phenomena beyond the boundaries of a conventional classroom. This is the key to teach and learn science effectively and can be assisted by technology as a pedagogical tool. The i2Flex model was implemented in a High School Science IB class as online/virtual laboratory investigations, in an effort to enhance high cognitive skills and academic performance of students. By allowing students to self-pace and self-direct their learning and practice to some extent, students not only engaged more actively in the science curriculum but improved their practical, writing and even collaborative skills. Teaching time in class became more flexible and productive and addressed areas of learning, such as critical thinking, analysis and elaboration of performed work, which have always puzzled students and perhaps lowered academic outcome.

Content analysis of media coverage provided a setting for group work, critical thinking, research, and data analysis. The analysis was motivated by a series of news stories that had damaged the reputation of the local community. The question was whether local news coverage was negative toward the business community. A business class addressed the problem and found that articles that business would view as favorable predominated. Based on their research, the class formulated a public relations strategy. Although this setting is a business class, content analysis of news media would work in other classes that emphasize critical thinking and problem solving.

Texte intégralRésumé :
The characterization of platelet reactive alloantibodies and autoantibodies is mandatory for the diagnosis of posttransfusion purpura, neonatal alloimmune thrombocytopenia, autoimmune thrombocytopenia and for the selection of platelet donors prior to platelet transfusions in immunized polytransfused patients. The platelet immunofluorescence test is suitable for the detection of platelet reactive antibodies. In many cases, however, mixtures containing different platelet reactive antibodies have to be dissected.In order to analyze these sera, we have developed a novel enzyme immunoassay based upon monoclonal antibody specific immobilization of platelet antigens (MAIPA). In brief, platelets are incubated simultaneously with the (human) serum to be investigated and a monoclonal (mouse) antibody directed against an epitope on the same platelet membrane glycoprotein (GP). Platelets are then washed and solubilized in TRIS buffered saline containing NP40. The lysed platelets are then pipetted into the wells of microtiter plates, coated with goat anti mouse IgG where mouse anti GP-complexes are immobilized. Human platelet reactive antibodies on the same GP are detected using enzyme labelled goat anti human IgG, IgM, or IgA, respectively. Using mab Gi5, mab FMC25, mab w6.32 directed against epitopes on the glycoprotein complex IIb/IIIa, glycoprotein Ib and HLA class I molecule, respectively, and a panel of typed platelet donors, even sera containing different platelet reactive antibodies are readily analyzed. Results of experiments with platelet specific alloantibodies (anti P1A1, anti P1A2 and anti Bak(a)), autoantibodies (against the GP Ilb/IIIa complex and GP Ib) and a drug dependent antibody show that this assay allows to discriminate all these different platelet reactive antibodies.

Dans ASME 2018 Pressure Vessels and Piping Conference. American Society of Mechanical Engineers, 2018. http://dx.doi.org/10.1115/pvp2018-85144.
Texte intégralRésumé :
The super pipe nozzles in nuclear power plants are usually designed to be in compliance with the requirements of Class 2 piping of Section III of the ASME Boiler and Pressure Vessel Code. The stress indices B2 and stress intensification factor i are required for the stress evaluation. In the past two decades, the hot extrusion forming technology has been widely used to manufacture those nozzles, instead of traditional insert weldolets. However, previous extruded nozzle stress analyses have shown B2 that the calculated stresses may exceed the limits in some working conditions. The objective of present study is to determine the stress indices and stress intensification factor for an extruded nozzle of the supper pipe by the finite element method and to evaluate the conservatism of those factors from the ASME Code formulae. In this paper, a three-dimensional finite element model of an extruded nozzle is developed. Four load cases are considered, which are corresponding to an in-plane bending moment and an out-plane bending moment applied at the run pipe side and at the branch pipe side, respectively. The magnitude of bending moment is assumed to be 1000Nm. The stress indices B2r, B2b, C2r, C2b, K2r and K2b, where the subscript r and b refer to the run pipe and B2r the branch pipe, are calculated based on the finite element analysis results. The stress intensification factor ir and ib are determined by the empirical formula: ir = C2r*K2r/2 and ib = C2b*K2b/2. Further, the developed factors are compared with those calculated from the ASME code formulae. It is found that the stress indices B2r and B2b obtained from the linear elastic finite element analysis are conservative. Currently, the values of B2r and B2b gained from the ASME code formulae are more appropriate for the stress evolution. The stress intensification factors ir and ib obtained from the analytical determination are lower than those calculated from the ASME code formula. For the extrude nozzle studied, the factor ir decreases 30% and the factor ib decreases about 3.3%.

Consumers increasingly share their opinions about products in social media.However, the analysis of this user-generated content is limited either to small,in-depth qualitative analyses or to larger but often more superficial analysesbased on word frequencies. Using the example of online comments aboutorganic food, we suggest a three-step methodological approach of how latestdeep neural networks can scale up the insights of qualitative analyses. First, aqualitative content analysis defines a class system of opinions. Second, a pre-trained neural network, the Universal Sentence Encoder, uses this class systemto automatically classify the same data by finding similar opinions. Third, theautomatic classification results are evaluated based on several criteria. Wefind coherent results of qualitative and automated classification proving theability of Universal Sentence Encoder to classify text. After this validation,Universal Sentence Enconder can be used to classify larger data sets onorganic food. The suggested approach allows to scale up sample size whilemaintaining the detail of class systems provided by qualitative contentanalyses. The approach can be applied to different domains and supportconsumer and public opinion researchers as well as marketing practicionersin further uncovering the potential of insights from user-generated content.

Zobeiry, Nima. « Sensitivity of the Effective Seismic Support Damping in a Class I Piping System to Analysis Parameters ». Dans ASME 2009 Pressure Vessels and Piping Conference. ASMEDC, 2009. http://dx.doi.org/10.1115/pvp2009-77938.
Texte intégralRésumé :
It is understood that the level of seismic damping in a piping system is strongly influenced by the supports. Put differently, the supports contribute to an effective damping that can be considered in the seismic analysis of the piping system. This paper investigates the issue for the feeder pipes of a CANDU™ reactor. Feeders are numerous class I pipes in parallel, which are separated by frictional spacer elements. The results of a time history analysis, taking into account different damping mechanisms, are compared to those from a response spectrum analysis to deduce the effective damping in the system. The sensitivity of the effective damping to different parameters, such as the coefficient of friction and the input frequency content, is investigated.

Texte intégralRésumé :
The Sunshine Coast (unless otherwise specified, Sunshine Coast refers to the region which includes both Sunshine Coast and Noosa council areas) is a classic regional hotspot. In many respects, the Sunshine Coast has assets that make it the “Goldilocks” of Queensland hotspots: “the agility of the region and our collaborative nature is facilitated by the fact that we're not too big, not too small - 330,000 people” (Paddenburg, 2019); “We are in that perfect little bubble of just right of about everything” (Erbacher 2019). The Sunshine Coast has one of the fastest-growing economies in Australia. Its population is booming and its local governments are working together to establish world-class communications, transport and health infrastructure, while maintaining the integrity of the region’s much-lauded environment and lifestyle. As a result, the Sunshine Coast Council is regarded as a pioneer on smart city initiatives, while Noosa Shire Council has built a reputation for prioritising sustainable development. The region’s creative economy is growing at a faster rate that of the rest of the economy—in terms of job growth, earnings, incomes and business registrations. These gains, however, are not spread uniformly. Creative Services (that is, the advertising and marketing, architecture and design, and software and digital content sectors) are flourishing, while Cultural Production (music and performing arts, publishing and visual arts) is variable, with visual and performing arts growing while film, television and radio and publishing have low or no growth. The spirit of entrepreneurialism amongst many creatives in the Sunshine Coast was similar to what we witnessed in other hotspots: a spirit of not necessarily relying on institutions, seeking out alternative income sources, and leveraging networks. How public agencies can better harness that energy and entrepreneurialism could be a focus for ongoing strategy. There does seem to be a lower level of arts and culture funding going into the Sunshine Coast from governments than its population base and cultural and creative energy might suggest. Federal and state arts funding programs are under-delivering to the Sunshine Coast.

Bondarenko, Olga V. The didactic potential of virtual information educational environment as a tool of geography students training. [б. в.], février 2020. http://dx.doi.org/10.31812/123456789/3761.
Texte intégralRésumé :
The article clarifies the concept of “virtual information educational environment” (VIEE) and examines the researchers’ views on its meaning exposed in the scientific literature. The article determines the didactic potential of the virtual information educational environment for the geography students training based on the analysis of the authors’ experience of blended learning by means of the Google Classroom. It also specifies the features (immersion, interactivity, and dynamism, sense of presence, continuity, and causality). The authors highlighted the advantages of virtual information educational environment implementation, such as: increase of the efficiency of the educational process by intensifying the process of cognition and interpersonal interactive communication; continuous access to multimedia content both in Google Classroom and beyond; saving student time due to the absence of necessity to work out the training material “manually”; availability of virtual pages of the virtual class; individualization of the educational process; formation of informational culture of the geography students; and more productive learning of the educational material at the expense of IT educational facilities. Among the disadvantages the article mentions low level of computerization, insignificant quantity and low quality of software products, underestimation of the role of VIЕЕ in the professional training of geography students, and the lack of economic stimuli, etc.

Texte intégralRésumé :
Numerous studies have emerged so far on Covid-19 (SARS-CoV-2) across different disciplines. There is virtually no facet of human experience and relationships that have not been studied. In Nigeria, these studies include knowledge and attitude, risk perception, public perception of Covid-19 management, e-learning, palliatives, precautionary behaviours etc.,, Studies have also been carried out on public framing of Covid-19 discourses in Nigeria; these have explored both offline and online messaging and issues from the perspectives of citizens towards government’s policy responses such as palliative distributions, social distancing and lockdown. The investigators of these thematic concerns deployed different methodological tools in their studies. These tools include policy evaluations, content analysis, sentiment analysis, discourse analysis, survey questionnaires, focus group discussions, in depth-interviews as well as machine learning., These studies nearly always focus on the national government policy response, with little or no focus on the constituent states. In many of the studies, the researchers work with newspaper articles for analysis of public opinions while others use social media generated contents such as tweets) as sources for analysis of sentiments and opinions. Although there are others who rely on the use of survey questionnaires and other tools outlined above; the limitations of these approaches necessitated the research plan adopted by this study. Most of the social media users in Nigeria are domiciled in cities and their demography comprises the middle class (socio-economic) who are more likely to be literate with access to internet technologies. Hence, the opinions of a majority of the population who are most likely rural dwellers with limited access to internet technologies are very often excluded. This is not in any way to disparage social media content analysis findings; because the opinions expressed by opinion leaders usually represent the larger subset of opinions prevalent in the society. Analysing public perception using questionnaires is also fraught with its challenges, as well as reliance on newspaper articles. A lot of the newspapers and news media organisations in Nigeria are politically hinged; some of them have active politicians and their associates as their proprietors. Getting unbiased opinions from these sources might be difficult. The news articles are also most likely to reflect and amplify official positions through press releases and interviews which usually privilege elite actors. These gaps motivated this collaboration between Ekiti State Government and the African Leadership Centre at King’s College London to embark on research that will primarily assess public perceptions of government leadership response to Covid-19 in Ekiti State. The timeframe of the study covers the first phase of the pandemic in Ekiti State (March/April to August 2020).

Jander, Georg, et Daniel Chamovitz. Investigation of growth regulation by maize benzoxazinoid breakdown products. United States Department of Agriculture, janvier 2015. http://dx.doi.org/10.32747/2015.7600031.bard.
Texte intégralRésumé :
Introduction Previous research had suggested that benzoxazinoids, a class of defensive metabolites found in maize, wheat, rye, and wild barley, are not only direct insect deterrents, but also influence other areas of plant metabolism. In particular, the benzoxazinoid 2,4-dihydroxy-7-methoxy-2H-1,4-benzoxa- zin-3(4H)- one (DIMBOA) was implicated in: (i) altering plant growth by interfering with auxin signaling, and (ii) leading to the induction of gene expression changes and secondary plant defense responses. The overall goal of this proposal was to identify mechanisms by which benzoxazinoids influence other aspects of plant growth and defense. Specifically, the following hypotheses were proposed to be tested as part of an approved BARD proposal: Benzoxazinoid breakdown products directly interfere with auxin perception Global changes in maize and barley gene expression are induced by benzoxazinoid activation. There is natural variation in the maize photomorphogenic response to benzoxazinoids. Although the initial proposal included experiments with both maize and barley, there were some technical difficulties with the proposed transgenic barley experiments and most of the experimental results were generated with maize. Summary of major findings Previous research by other labs, involving both maize and other plant species, had suggested that DIMBOA alters plant growth by interfering with auxin signaling. However, experiments conducted in both the Chamovitz and the Jander labs using Arabidopsis and maize, respectively, were unable to confirm previously published reports of exogenously added DIMBOA effects on auxin signaling. Nevertheless, analysis of bx1 and bx2 maize mutant lines, which have almost no detectable benzoxazinoids, showed altered responses to blue light signaling. Transcriptomic analysis of maize mutant lines, variation in inbred lines, and responses to exogenously added DIMBOA showed alteration in the transcription of a blue light receptor, which is required for plant growth responses. This finding provides a novel mechanistic explanation of the trade-off between growth and defense that is often observed in plants. Experiments by the Jander lab and others had demonstrated that DIMBOA not only has direct toxicity against insect pests and microbial pathogens, but also induces the formation of callose in both maize and wheat. In the current project, non-targeted metabolomic assays of wildtype maize and mutants with defects in benzoxazinoid biosynthesis were used to identify unrelated metabolites that are regulated in a benzoxazinoid-dependent manner. Further investigation identified a subset of these DIMBOA-responsive compounds as catechol, as well as its glycosylated and acetylated derivatives. Analysis of co-expression data identified indole-3-glycerol phosphate synthase (IGPS) as a possible regulator of benzoxazinoid biosynthesis in maize. In the current project, enzymatic activity of three predicted maize IGPS genes was confirmed by heterologous expression. Transposon knockout mutations confirmed the function of the maize genes in benzoxazinoid biosynthesis. Sub-cellular localization studies showed that the three maize IGPS proteins are co-localized in the plastids, together with BX1 and BX2, two previously known enzymes of the benzoxazinoid biosynthesis pathway. Implications Benzoxazinoids are among the most abundant and effective defensive metabolites in maize, wheat, and rye. Although there is considerable with-in species variation in benzoxazinoid content, very little is known about the regulation of this variation and the specific effects on plant growth and defense. The results of this research provide further insight into the complex functions of maize benzoxazinoids, which are not only toxic to pests and pathogens, but also regulate plant growth and other defense responses. Knowledge gained through the current project will make it possible to engineer benzoxazinoid biosynthesis in a more targeted manner to produce pest-tolerant crops without negative effects on growth and yield.
