Helicobacter pylori adhesion and patho-adaptation : the role of BabA and SabA adhesins in persistent infection and chronic inflammation
No full textHelicobacter pylori (H. pylori) is a human-specific gastric pathogen which is responsible for a spectrum of diseases ranging from superficial gastritis to gastric and duodenal ulceration, and which is also highly associated with gastric cancer. The pathogenesis of severe gastric disorders caused by H. pylori is multifactorial and involves complex interactions between the microbe and the gastric mucosa. H. pylori expresses several adhesion proteins. These molecules have important roles in the establishment of persistent infection and chronic inflammation, which cause tissue damage. The aim of this thesis was to study the attachment of this bacterium to human gastric epithelium, mediated by blood group antigens in both health and disease. One of the bestcharacterized H. pylori adhesins is the histo-blood group antigen binding adhesin (BabA), which binds specifically to the Lewis b antigen (Leb) in the gastric mucosa. A protective mucus layer lines the stomach. The mucosal glycosylation patterns (GPs) vary between different cell lineages, different locations along the gastrointestinal (GI) tract and different developmental stages. In addition, GPs undergo changes during malignant transformation. MUC5AC is a mucin molecule produced by the surface epithelium. Three distinctly different types of human gastrointestinal tissue were studied by bacterial adherence analysis in situ. MUC5AC is the most important carrier of Leb and the new results demonstrate that it forms major receptors for H. pylori adherence. By analysing an H. pylori babA-deletion mutant, a novel adhesin-receptor binding mode was found. Surprisingly, the mutant bound efficiently to both human gastric mucosa and to gastric mucosa of Leb transgenic mice. The sialylated and fucosylated blood group antigen, sialyl-dimeric-Lewis x (sdiLex), was structurally identified as the new receptor. A positive correlation was found between adherence of H. pylori to sialyl-Lewis x (sLex) and elevated levels of inflammation response in the human gastric mucosa. These results were supported by detailed analysis of sialylated and fucosylated blood group antigen glycosylation patterns and, in addition, in situ bacterial adherence to gastric mucosa of experimentally challenged Rhesus monkey. The cognate sialic acid-binding adhesin (SabA) was purified by the retagging technique, and the corresponding sabA-gene was identified. H. pylori lipopolysaccharide (LPS) contains various Lewis blood group antigens such as Lewis x (Lex) and Lewis y (Ley). Additional bacterial adherence modes, which are independent of the BabA and/or SabA adhesins, could possibly be mediated by Lex interactions. Adherence of a clinical isolate and its corresponding Lex mutant to human gastric mucosa with various gastric pathologies was studied in situ. The results suggest that H. pylori LPS plays a distinct but minor role in promotion of bacterial adhesion. Taken together, the results suggest mechanisms for continuous selection of H. pylori strains, involving capacity to adapt to changes in the local environment such as shifts in cell differentiation and associated glycosylation patterns. Adherence of H. pylori is dependent on both the BabA and the SabA adhesin. Multi-step dependent attachment mechanisms may direct the microbes to distinct ecological niches during persistent infections, driving the chronic inflammation processes further toward the development of peptic ulcer disease and/or malignant transformation. Key words: H. pylori, BabA, adhesin, Lewis b, MUC5AC, sialyl-dimeric-Lewis x, chronic inflammation, SabA, Lewis x, LPS
Barriers and overcoming strategies to supply chain sustainability innovation
No full textThis study identifies a list of barriers that hinders adoption, implementation and upscaling of sustainable supply chain innovation in the manufacturing industry. It further proposes overcoming strategies that seek to aid management decision to dealing with these barriers systematically. A multi-criteria decision analysis method, the Best-Worst Method (BWM), is adopted to aid in the evaluation and prioritisation of the barriers and their overcoming strategies within the Indian manufacturing industry, an emerging economy. The results depict that, “lack of technical expertise and training”, “lack of R&D and innovation capabilities”, “popularity of traditional technology”, “high initial investment in latest technology” and “fear of extra workload and loss of flexibility” are the top five barriers that confronts the Indian manufacturing companies in their quest for adopting and implementing sustainable supply chain innovation practices. In addition, the overcoming strategic pathway for dealing with these barriers are provided. The findings provide managerial and policy insights for guiding the formation of strategic operations framework and resource allocation if these Indian manufacturing firms seeks to build sustainability into their supply chain innovations
CONTRASTING NARRATIVES OF RELIGIOUS CONVERSION: STUDY OF “KISAH MUALAF” VERTIZONE TV AND LOG IN HUSEIN JAFAR
No full textWith the increasing trend of religious mediatization, the topic of religious conversion has gained significant attention in the media, both as news content and as part of Islamic dakwah narratives in Indonesia. This narrative has been widely disseminated through new media and the internet, where religious conversion stories are frequently featured in Islamic dakwah videos that attract a large audience. This article examines the “Kisah Mualaf” segment on the Vertizone TV channel and the “Log In” program on Deddy Corbuzier’s channel. “Kisah Mualaf`” presents narratives of dramatic transformation of the converts, biblical validation, and the perceived mutual threat between Islam and Christianity, shaping a dakwah content formula that represents a new generation of convert preachers. On the other hand, “Log In”, hosted by Husein Jafar, frames religious conversion narratives through comedic gimmicks while emphasizing Indonesian pluralism, reflecting the perspectives of moderate Islamic groups. Through this study, the author explores the contrasting discourses on religious conversion as a prominent narrative within Indonesia’s digital dakwah sphere. Employing content analysis, netnography, and a review of existing literature, the author argues that two dominant religious conversion narratives have emerged among digital preachers, constituting not only a competition for audience engagement but also a contestation of discourse within Indonesia’s Islamic digital dakwah landscape.
Infodemiological data of high-school drop-out related web searches in Canada correlating with real-world statistical data in the period 2004–2012
No full textAbstractThe present data article describes high-school drop-out related web activities in Canada, from 2004 to 2012, obtained mining Google Trends (GT), using high-school drop-out as key-word. The searches volumes were processed, correlated and cross-correlated with statistical data obtained at national and province level and broken down for gender. Further, an autoregressive moving-average (ARMA) model was used to model the GT-generated data. From a qualitative point of view, GT-generated relative search volumes (RSVs) reflect the decrease in drop-out rate. The peak in the Internet-related activities occurs in 2004 (56.35%, normalized value), and gradually declines to 40.59% (normalized value) in 2007. After, it remains substantially stable until 2012 (40.32%, normalized value). From a quantitative standpoint, the correlations between Canadian high-school drop-out rate and GT-generated RSVs in the study period (2004–2012) were statistically significant both using the drop-out rate for academic year and the 3-years moving average.Examining the data broken down by gender, the correlations were higher and statistically significant in males than in females. GT-based data for drop-out resulted best modeled by an ARMA(1,0) model. Considering the cross correlation of Canadian regions, all of them resulted statistically significant at lag 0, apart from for New Brunswick, Newfoundland and Labrador and the Prince Edward island. A number or cross-correlations resulted statistically significant also at lag −1 (namely, Alberta, Manitoba, New Brunswick and Saskatchewan)
A Critical Review on the Book Hussain Ibn Musa (AS), His Life, Personality, Sepulcher
No full textHussain ibn Musa ibn Jafar is a famous Alawi person who transmitted some Hadiths from his father Imam Musa al Kazim and his brother, Imam Ali ibn Musa al Rida (A.S). This lofty position and proximity to the Imamate line, caused the construction of some attributed Sepulchers to him in many cities, of which Tabas, located in the east of Iran, has more fame. Ali Akhavan Mahdavi has written a book on this important personality, his life, and his real place of burring. The present study aims to examine the book critically, therefore, tries to introduce and examine the book, then discusses some problems in it and presents suggestions regarding both the form and the content. So, we prepare our study with the use of a descriptive-analytical approach and of course a special usage of the main historical sources to which compare the contents of them. In conclusion, the author reached some important innovations in comparison with similar sources and studies, and it is completely clear by analyzing the content of hadith and genealogy books. Examination of the Akhavan Mahdavi's book showed that although this book has many advantages and has been effective on subsequent works written on this subject, but shortcomings such as lack of research background and critique of sources, the author's little use of Hadith and Rijal sources are among the cons. Some of the author's citations have diminished the book's credibility
Validation of the effect of increasing CO2 concentration on yield of wheat plant using meta-analysis method
No full textIntroduction: Concerns about the potential effects of climate change on agricultural products have prompted significant research in the past decade. Cereals are the most important food in the world population and among the various cereals, wheat plays the most important role. In our country, wheat is the most important crop in the country and has a significant role in feeding people. Due to the importance of this plant in providing food security, this study was conducted to investigate the increase in the concentration of carbon dioxide on the yield of wheat. For this purpose, meta-analysis method was used to quantitatively compare the effect of CO2 on wheat crop yield. Material and methods: The purpose of meta-analysis is to obtain more information than available information. In order to obtain the necessary data for the present study, the printed sources review method was used. 75 articles were extracted on the effect of increasing carbon dioxide concentration on wheat yield, then duplicate articles and articles that lacked the desired data were removed and among the remaining articles CO2 information, sample size, average and standard deviation was extracted. In the next step, these values were recorded in Excel software and finally, using Stata 16 software, the necessary forest plot and funnel plot were drawn, and to investigate the publication bias among the studies using the trim and fill method and drawing its graphs, this was investigated. Results and discussion: The results of the forest plot showed that after deleting the outlier data, the two groups T2 (15-25) and T3 (35_25) have a greater final size effect (about 1.6), which indicates that with increasing temperature up to Wheat plant yield increased by 35 ° C. Also, group T0, which is not mentioned in the articles of this group, has the lowest size effect (0.38). So, it can be inferred that the yield of wheat plant will increase with increasing temperature between 15 to 35 ° C and with increasing CO2 concentration in this temperature range. Examination of the funnel plot showed that most studies had accumulated at the top of the diagram. These studies have smaller standard error, larger sample size and higher accuracy. Publication bias was also observed in a positive direction. After drawing the funnel plot, the trim and fill method was used to estimate the potential missing studies due to the biased dissemination in the funnel plot and the adjustment of the estimate of their overall effect. After performing the trim and fill method, 6 dots marked in orange are added. These points are missing studies that need to be placed to create symmetry in the graph. This indicates that previous studies have been positive. Conclusion: The results of this study showed that the studies conducted in recent years have more reliable results (due to the larger sample size and greater accuracy in the results of these studies). Also, considering that increasing the concentration of CO2 can also cause an increase in temperature, it is suggested that in future studies, studies that have examined the interaction between increasing the concentration of CO2 and increasing the temperature simultaneously on important crops, using the meta-analysis method should be examined
Piecewise linear value functions for multi-criteria decision-making
No full textMulti-criteria decision-making (MCDM) concerns selecting, ranking or sorting a set of alternatives which are evaluated with respect to a number of criteria. There are several MCDM methods, the two core elements of which are (i) evaluating the performance of the alternatives with respect to the criteria, (ii) finding the importance (weight) of the criteria. There are several methods to find the weights of the criteria, however, when it comes to the alternative measures with respect to the criteria, usually the existing MCDM methods use simple monotonic linear value functions. Usually an increasing or decreasing linear function is assumed between a criterion level (over its entire range) and its value. This assumption, however, might lead to improper results. This study proposes a family of piecewise value functions which can be used for different decision criteria for different decision problems. Several real-world examples from existing literature are provided to illustrate the applicability of the proposed value functions. A numerical example of supplier selection (including a comparison between simple monotonic linear value functions, piecewise linear value functions, and exponential value functions) shows how considering proper value functions could affect the final results of an MCDM problem.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Transport and Logistic
Features of auteur cinema in the films of Iranian director Jafar Panahi and sociopolitical context.
No full textMultimediju komunikācijaInformācijas un komunikācijas zinātnesMultimedia CommunicationInformation and Communication SciencesŠogad februārī tika atbrīvots Irānā prettiesiski ieslodzītais disidents Džafars Panahi, kura filmām uz politiskā režīma likto šķēršļu fona ir nozīmīga loma irāņu kino. Bakalaura darba “Autorkino iezīmes irāņu režisora Džafara Panahi filmās un sociālpolitiskais konteksts” mērķis bija noskaidrot raksturīgākās autorkino iezīmes Panahi kinodarbos, ņemot vērā kinodarbu sociālpolitisko kontekstu. Galvenie teorētiskie ietvari bija autorkino teorija, kino valoda (naratīvs, mizanscēna, operatora māksla, montāža, skaņa), irāņu kino (arī politika, sociālie procesi) un Panahi biogrāfija, filmogrāfija. Izmantojot kvalitatīvo kontentanalīzi, kvantitatīvo kontentanalīzi un kontekstuālo analīzi, darbā pētītas filmas “Baltais balons”, “Spogulis”, “Aplis”, “Tumšsarkanais zelts”, “Aizmugurē”, kā arī darbi, kas tapuši laikā, kad režīms autoram bija aizliedzis veidot filmas, proti, “Šī nav filma”, “Aizvērtais aizkars”, “Taksometrs” un “Trīs sejas”.
Pētījumā izdarīti vairāki secinājumi par Panahi kino raksturīgajām iezīmēm un filmu sociālpolitisko kontekstu. Par pirmo - kā piemērus var minēt viņa sarežģītos naratīvus, fikcijas un realitātes mijiedarbi, “ceturtās sienas” laušanu, Irānā aktuālo problēmu atspoguļojumu, kas balstīts reālās pieredzēs, notikumos, atvērtos finālus, simbolus, metaforas, alegorijas, cikliskumu, intertekstualitāti (t.sk. vizuālos citātus), marginalizētos varoņus, kas nav ļaunprātīgi un pastāvīgi tiek pakļauti sociālās vides ietekmei, filmēšanu reālās lokācijās, videokameras dieģetizēšanu, vardarbības klātbūtni bez nosakāma vardarbības avota, varoņu radītu inscenējumu, izmantojot mizanscēnu, neprofesionālos aktierus, kas tēlo sevi, garos plānus un augsto ASL (31 sekunde), apļveida kameras kustību, filmējumu ar dažāda veida kamerām lieguma laikā, nedieģētiskos iestarpinājumus u.c. Analizējot otro, atklāti sociālpolitiskie notikumi, kas klātesoši filmēšanas procesā vai iezīmēti filmās, sākot ar bērnu aktieriem, dzimumu un ekonomisko nevienlīdzību un beidzot ar represijām pret radošās industrijas pārstāvjiem.In February of this year, Jafar Panahi, a dissident illegally imprisoned in Iran, was released from prison. His films, made against the backdrop of obstacles imposed by the political regime, play an important role in Iranian cinema. The aim of the bachelor’s thesis “Features of auteur cinema in the films of Iranian director Jafar Panahi and socio-political context” was to find out the most characteristic features of auteur cinema in Panahi’s films, considering the socio-political context of these films. The main theoretical frameworks were auteur theory, the language of film (narrative, mise-en-scene, cinematography, montage, sound), Iranian cinema (also politics, social processes) and Panahi’s biography, filmography. By using qualitative content analysis, quantitative content analysis and contextual analysis, the thesis examines the films “The White Balloon”, “The Mirror”, “The Circle”, “Crimson Gold”, “Offside”, as well as works created when the author was banned from making films by the regime, namely “This Is Not a Film”, “Closed Curtain”, “Taxi” and “3 Faces”.
The research draws several conclusions about the characteristic features of Panahi’s cinema and the socio-political context of the films. About the former - as examples can be mentioned his complex narratives, interactions between fiction and reality, breaking of the fourth wall, representation of current issues in Iran based on real experiences, events, open endings, symbols, metaphors, allegories, cyclicality, intertextuality (including visual quotations), marginalized characters who are not evil and are constantly exposed to the influence of their social environment, filming in real locations, diegetization of the video camera, the presence of violence without an identifiable source, staging created by characters using mise-en-scene, non-professional actors playing themselves, long takes and high ASL (31 seconds), circular camera movement, filming with different types of cameras during the ban, nondiegetic inserts etc. By analyzing the latter, the socio-political events present in the filming process or marked in the films, starting with child actors, gender inequality, economic inequality and ending with repression against representatives of the creative industry, were revealed
