Urinary tract infection (UTI) is common in children. It is caused by bacteria and can lead to complications such as renal scarring in cases of late diagnosis and a lack of early treatment. Vesicoureteral reflux (VUR) occurs when urine flows from the bladder to the ureter and kidney, and is more common in children with UTI. VUR predisposes patients to pyelonephritis and can cause renal scarring. This retrospective study aimed to determine whether VUR was associated with the evolution to renal scarring in 132 infants aged 9 days to 24 months admitted to a tertiary care hospital in Jeddah, Saudi Arabia, with the first episode of febrile UTI (mean age = 4.48 months [standard deviation = 5.48]; 82 [62.1%] males; 50 [37.9%] females). Data from their medical records were investigated

for VUR and renal scarring. The VUR was related to renal scarring (P = 0.001). C-reactive protein (CRP) levels were significantly higher in patients with VUR (P = 0.027) and renal scars (P = 0.05). There was a statistically significant difference between VUR and renal scarring with the first UTI (P = 0.001). In conclusion, our study revealed a significant association of CRP with renal scarring (P = 0.05) and VUR and (P = 0.027).

To bridge the gap between demand and supply of organs, deceased donors with extreme ages can be utilized. The object of this study was to compare elderly with non-elderly donors and to assess the predictors of organ utilization or wastage. This was a retrospective chart analysis. Univariate and multivariate logistic regression analysis of cohorts was carried out to predict organ utilization or wastage. Of the 716 deceased donors, 16.2% were elderly (≥60 years) and 83.8% were not elderly (≤59 years). Donors in the elderly cohort were more likely to be diabetic, hypertensive, overweight, and smokers compared with non-elderly donors. They had deranged terminal creatinine and succumbed to cerebrovascular accident or intracerebral hemorrhage. They had a high kidney donor risk index (KDRI) of 1.83 ± 0.46. Those in the younger donor cohort, were more likely to have succumbed to road traffic accident-associated traumatic brain injury, were subjected to more efforts to revive them in the intensive care unit via cardiopulmonary resuscitation, had deranged liver function tests, and had a KDRI of 0.93 ± 0.28. The kidney discard rate (KDR) and liver discard rate (LDR) in the elderly donors was 50% and 8.6%, respectively (vis-a-vis the non-elderly at 13.3 % and 7.5%). The KDR was significantly higher than the LDR in elderly donors. The main reason for this was the high number of “marginal kidneys”. We revealed that elderly donors formed a significant proportion of deceased donors. The utilization of the liver from deceased donors was more frequent compared with the kidney.
Study of Correlation between Right Ventricular Ejection Fraction with Left Ventricular Ejection Fraction in Patients of Chronic Heart Failure with Diabetes, using Two-dimensional Echocardiography
Authors: Shah Vandan , Mane Shailendra , Khyalappa Rajesh
Published: August 2023

Introduction:

Diabetes is one of the most significant health issues. Patients with type 2 diabetes mellitus (DM) are more susceptible to an elevated cardiovascular risk, including heart failure. Echocardiography should help in the early identification of these myocardial abnormalities that would help properly treat these individuals.

Materials and Methods:

The study was conducted over 18 months and focused on patients with diabetes and chronic heart failure who met inclusion and exclusion criteria. Ethical approval was obtained, and all patients provided their consent to participate in the study. The participants underwent a two-dimensional echocardiogram to assess their heart function, and relevant laboratory tests, imaging results, and information about medications received during their hospitalization were recorded.

Results:

As per The New British Society of Echocardiography criteria, 64 patients had impaired left ventricular ejection fraction (LVEF), and 31 had severely impaired LVEF. The majority of the patients with impaired LVEF, 53%, also had impaired right ventricular ejection fraction (RVEF). Of 31 patients with severely impaired LVEF, 58% also had severely impaired RVEF. The association between LVEF and RVEF is statistically significant (P < 0.05). There is a positive correlation between LVEF (%) and RVEF (%), which was statistically significant (P < 0.05). Severe dysfunction in LVEF is also present in patients with severe dysfunction of RVEF.

Conclusion:

The majority of patients who had reduced LVEF also had reduced RVEF, and this association was significant. While there was a correlation between glycosylated hemoglobin levels and both LVEF and RVEF, it was not statistically significant. Hence, patients who are identified to have lower LVEF should also be evaluated for RVEF.
Lexical Ambiguities in the Vocabulary of Statistics
Authors: Whitaker Douglas
Published: August 2023

Lexical ambiguities exist when two different meanings are ascribed to the same word. Such lexical ambiguities can be particularly problematic for learning material with technical words that have everyday meanings that are not the same as the technical meaning. This study reports on lexical ambiguities in six statistical words germane to statistics classes arbitrary, model, random, range, uniform, and variable based on data collected from an Advanced Placement (AP) Statistics course taught in the southeastern United States. Data was collected at the beginning and end of an academic year. Of the six words studied, fourmodel, random, uniform, and variable -were found to have substantial lexical ambiguities.

Published: August 2023

Humans possess a remarkable ability to recognize both simple patterns such as shapes and handwriting and very complex patterns such as faces and landscapes. To investigate one small aspect of human pattern recognition, in this study participants position lines of "best fit" to two-dimensional scatter plots of data. The study investigates the variation in participants' fits and whether there is some consistent metric being used in fitting the lines. For example, is there a natural tendency toward fitting lines similarly to one of the standard regression lines: vertical, horizontal, or orthogonal. This study also investigates the effect of outliers on the line a participant fits to a scatter plot with a strong linear trend and provides guidance for future inquiries.
Teaching Mathematics for Understanding in Primary Schools: Could Teaching for Mathematising be a Solution?
Authors: Lai Mun Yee , Kinnear Virginia , Fung Chun Ip
Published: August 2023

This is a position paper in which we argue for Teaching for Mathematising as a pedagogy that supports teaching mathematics for understanding in primary school. Mathematics education in Australia currently emphasises teaching for mathematical understanding, a shift that redirects children's learning from merely memorising computation procedures to helping children construct knowledge of the mathematics that informs mathematical concept and processes. The shift to teaching for understanding however is not reflected in students' item responses in international and national achievement studies. This paper provides one example that illustrates a learning trajectory for supporting mathematical understanding of both conceptual and procedural knowledge through teaching that builds on the framework of Teaching for Mathematising. A corresponding field-test will then be used to illustrated how students learn pragmatically.
Mathematical Representational Code Switching
Authors: Bosse Michael J. , Bayaga Anass , Fountain Catherine , Slate Young Erica
Published: August 2023

This study investigates representational code-switching (RCS) by considering three high school students' communications in the process of comparing and contrasting pairs of representations (e.g., equation and graph) in the context of rational functions. Supporting this study is research in the realms of students interacting with mathematical representations, practicing language learning, and linguistic code-switching (LCS). Attention is given to assessing student mathematical understanding based on frequency and type of RCS performed. This investigation concludes that RCS demonstrates either weaker or stronger mathematical performance depending on whether the RCS evidences semantic elaboration, isomorphic and transcendent connections, and domain register knowledge.
Common Visual Representations as a Source for Misconceptions of Preservice Teachers in a Geometry Connection Course
Authors: Krajcevski Mile , Sears Ruthmae
Published: August 2023

In this paper, we demonstrate how atypical visual representations of a triangle, square or a parallelogram may hinder students' understanding of a median and altitude. We analyze responses and reasoning given by 16 preservice middle school teachers in a Geometry Connection class. Particularly, the data were garnered from three specific questions posed on a cumulative final exam, which focused on computing and comparing areas of parallelograms, and triangles represented by atypical images. We use the notions of concept image and concept definition as our theoretical framework for an analysis of the students' responses. Our findings have implication on how typical images can impact students' cognitive process and their concept image. We provide a number of suggestions that can foster conceptualization of the notions of median and altitude in a triangle that can be realized in an enacted lesson.
Early-Years Prospective Teachers' Definitions, Examples and Non-examples of Cylinder and Prism
Authors: Ulusoy Fadime
Published: August 2023

This study investigates early-years prospective teachers' definitions, examples, and non-examples of cylinder and prism. The data were collected from 72 early-years prospective teachers via written tasks and classroom discussions. In written tasks, they were requested to define and then to give different examples and non-examples of cylinder and prism. The results indicated that prospective teachers defined cylinder based on prototypical cylinder with circle bases without mentioning all critical attributes of cylinder. They mostly provided correct examples and non-examples for cylinder. They did not pay attention critical and non-critical attributes of prism. Some prospective teachers drew cone and pyramids as the examples of prism. Their daily-life examples had similarity with the examples presented in textbooks and other curriculum materials. This study revealed that there is relationship between prospective teachers' definitions, daily-life examples, drawings, and non-examples. Possible reasons for these results are discussed and elaborated.

Authors: Chipangura Addwell Tichafa , Aldridge Jill
Published: August 2023

The study reported in this article compared mathematics students in classes that were frequently exposed to multimedia (n=197 students in nine classes) with those that were not (n=168 students in seven classes). First, quantitative data were collected using students' self-reports on their engagement. Second, classroom observations and interviews with 10 students and six teachers were used to gather information that provided insights regarding the use of multimedia in mathematics classes. The results found statistically significant differences between the two groups, with students who were frequently exposed to multimedia reporting more learning goal orientations, task value, self-efficacy and self-regulation than their counterparts who were not. Further, exposure to multimedia was found to be differentially effective for male and female students. Statistically significant interactions were found between exposure to multimedia and gender for learning goal orientations, task value and self-efficacy with males reporting to be more engaged than females in classes that were frequently exposed to multimedia and less engaged than females in classes that were not frequently exposed to multimedia. The results of this study provide information to practitioners regarding approaches that could be used to improve students' engagement in mathematics learning.KEY WORDS: adaptive learning engagement, motivation, multimedia, self-regulation
Assessment of Vehicular Vision Obstruction due to Driver-Side
B-Pillar and Remediation with Blind Spot Eliminator
Authors: Baysal Dilara N.
Published: August 2023

Blind spots created by the driver-side B-pillar impair the ability of the driver
to assess their surroundings accurately, significantly contributing to the
frequency and severity of vehicular accidents. Vehicle manufacturers cannot
readily eliminate the B-pillar due to regulatory guidelines intended to protect
vehicular occupants in the event of side collisions and rollover incidents.
Furthermore, assistance implements utilized to counteract the adverse effects of
blind spots remain ineffective due to technological limitations and optical
impediments.

This paper introduces mechanisms to quantify the obstruction caused by the
B-pillar when the head of the driver is facing forward and turning 90°, typical
of an over-the-shoulder blind spot check. It uses the metrics developed to
demonstrate the relationship between B-pillar width and the obstruction angle.
The paper then creates a methodology to determine the movement required of the
driver to eliminate blind spots. Ultimately, this paper proposes a solution, the
Blind Spot Eliminator, and demonstrates that it successfully decreases both the
obstruction angle and, consequently, the required driver movement. The Blind
Spot Eliminator is a lens on the rear-most section of the left driver’s side
window that utilizes refraction to display objects in the surrounding areas. A
prototype of the Blind Spot Eliminator was constructed and experimented with
using a mannequin to model human vision in a typical passenger vehicle. The
results of this experiment illustrated a substantial improvement in viewing
ability, as predicted by earlier calculations. This paper concludes that the
proposed Blind Spot Eliminator has excellent potential to improve driver safety
and reduce vehicular accidents.

Published: August 2023

Multiple studies are currently, aimed at studying the mechanisms of the development of basic age-related pathologies, e.g., arterial hypertension (AH). We found no literature sources concerning associations between the levels of matrix metalloproteinase type 7 (MMP-7), tissue inhibitor of matrix metalloproteinases type (TIMP-1) and anthropometric data which could be useful for diagnosing age-associated, socially dependent diseases and metabolic disorders. The article presents the data on the state of proteolysis system and anthropometric data of 45 almost healthy women and 45 women with arterial hypertension (AH) aged from 59 to 74 years old. The levels of MMP-7 and TIMP-1 in blood serum were studied by sandwich-variant of ELISA test. The waist and neck volume were measured three times with a centimeter tape at an accuracy of 1 cm. Statistical processing of the obtained data was performed using analytical software IBM SPSS Statistics, v. 22.0. The results show some correlations between the levels of MMP-7 and TIMP-1, and the waist and neck sizes (WC). Lower levels of MMP-7 and TIMP-1 were registered in the group of practically healthy women as compared to the second (AH) study group (p 0.01). Anthropometric data were not markedly diverse: the waist size in the group of healthy women was less than in AH group (p 0.05), and values of neck volume did not differ significantly between the groups. When assessing the relationships in the group of practically healthy women, we recorded a direct significant correlation between the waist size and neck volume (r = 0.754, p 0.0001), while in the group of women with AH this relationship was weaker (r = 0.5782, p 0.0001). In addition, a similar correlation was found between MMP-7 and TIMP-1 levels in the both groups studied. In the group of healthy women this relationship was of medium strength (r = 0.657, p 0.0001), whereas in the group of women with AH it was stronger (r = 0.720, p 0.0001). The data obtained suggest the presence of metabolic disorders in the women with arterial hypertension and signs of proteolytic enzyme system disorders.
Features of T cell immunity depending on the content of natural killer cells in patients with acute coronary syndrome following COVID-19
Authors: Safronova Eleonora A. , Ryabova Liana V.
Published: August 2023

We examined 65 men with unstable angina and acute myocardial infarction (acute coronary syndrome - ACS) from 40 to 65 years old who had previously had COVID-19 and 20 people with ACS who had not undergone COVID-19. All persons also had hypertension, and they required stenting of the coronary arteries within the next 3 days after admission to the hospital. From the immunological parameters by flow cytometry on the Navios cytofluorimeter (BeckmanCoulter, USA), according to the standardized technology for assessing the lymphocytic link of immunity [1], the following were determined: ), CD45+ CD3+ CD8+ (cytotoxic T-lymphocytes), CD45+CD3-CD19+ (B-lymphocytes), CD45+CD3+CD16+CD56+ (TNK cells), CD45+CD3-CD16+CD56+ (natural killer cells), CD45+ CD3+CD4+CD25+CD127- (T-regulatory cells), CD45+ CD3+CD4+CD25+ (T-lymphocytes - early activation), CD45+CD3+HLA-DR (T-lymphocytes - late activation). All patients were divided into groups depending on the content of NK cells (natural killer cells). Patients who have had COVID-19 have 3 phenotypes of disorders (decreased NK cell count, normal and increased), while non-survivors have 2 phenotypes (decreased NK cell count and normal). The most severe condition and severity of immune disorders were found in patients who had undergone COVID-19. In patients with acute coronary syndrome and COVID-19, predominantly with normal and elevated levels of NK cells, compared with ACS patients without COVID-19, a more severe course of the disease was observed - patients with acute myocardial infarction prevailed, they had a higher mortality rate, the duration of treatment was increased, and stent thrombosis was also more common. In persons with ACS and COVID-19 with elevated NK cells, the maximum decrease in the T-cell immunity was observed: T-lymphocytes of general, T-lymphocytes-helpers, T-cytotoxic lymphocytes, T-lymphocytes of early activation, T-regulatory cells in absolute numbers compared to other groups. The lowest immunoregulatory index and, at the same time, the maximum number of T-NK-lymphocytes were observed in persons who had undergone COVID-19 and had reduced NK cells. The minimum number of T-NK lymphocytes was recorded in patients with low NK cells who did not have COVID-19. Minimal T-lymphocytes (CD45+CD3+CD4+HLA-DR+) of late activation were found in people who recovered from COVID-19 with elevated and normal NK cells. The lowest number of late activation regulatory T cells was observed in patients who did not have COVID-19, but were vaccinated, and had a normal content of NK cells. The study also allows us to more clearly define the groups of patients with ACS who need additional immunocorrection.

Published: August 2023

Severe mechanical injury is among the main reasons of disability and mortality in pediatric patients. The imbalance between the states of inflammation and immune suppression during the critical period of post-traumatic injury bears an elevated risk for infectious complications and/or multiple organ failure. The present study aimed to determine the informative immunological criteria in order to evaluate severity and prognosis for clinical outcomes in children from the severe injury group (SInj, ISS 16, n = 87); mild/moderate injury group (MInj, ISS 16, n = 34), as based on assessment of helper T cells (Th) ratios, i.e., Th17/Treg, T127hi/ Treg, and Th17/T127hi. The patients with severe injuries were classified by their outcomes (favorable, n = 47; unfavorable, n = 40), presence of infectious complications (IC, n = 16) and the development of multiple organ failure (MOF, n = 11). Th ratios were studied on the 1st, 3rd, 5th, 7th, 14th day after injury. For the Sinj group, a pronounced increase of Th17/Treg ratio in the acute post-traumatic period with a decrease by 14 days was revealed. The indices of T127hi/Treg ratio on the first day for the patients from Minj group corresponded to the values of control group and significantly differed from patients with SInj in the 3rd to 5th day. There are different kinetics of Th subset ratio in peripheral blood of children with severe injuries over time in different groups, as well as with/without MOF, in presence, or absence of infectious complications and different clinical outcomes. Significant differences in T127hi/Treg ratio level were found in group with IC from 1st to 3rd day and from 7th to 14th day. Significant differences in Th17/Treg ratio level were found in IC group (7th day), in MOF group on 14th day post-injury. The patients with MOF had lower median concentrations of Th17/Treg and T127hi/Treg than patients without MOF. The results of the study indicate that the levels of Th17/Treg and T127hi/Treg ratio in children may be used to predict outcome of the traumatic disease and assess the risk of infectious complications and multiple organ dysfunction syndrome.

Published: August 2023

The Parque Estadual de São Camilo (PESC) is one of the few forest fragments in the western Paraná, Southern Brazil, a region with a high agricultural activity. The objective of this study was to survey bat species in this park and determine the significance of this area for conservation of bat species. Samples were collected during four nights per month from September 2016 to August 2017, using mist nets placed at eight different sites in the PESC. A total of 380 individuals of three families and 12 species were captured. The most frequent and constant species were Artibeus lituratus, Sturnira lilium, and Artibeus fimbriatus. The most frequent dietary guild found was frugivorous, followed by insectivorous, omnivorous, and carnivorous. A higher species abundance was found in sites at the forest fragment edge. Two Phyllostominae species, Chrotopterus auritus and Phyllostomus hastatus, were found only in the interior of the forest fragment. Although no endangered bat species were identified, the preservation of forest areas in secondary succession, can benefit species that depends on conserved areas. Finally, we recommend conducting new studies within the park, with particular emphasis on unexplored areas, to shed light on the ecology and population dynamics of bats in PESC.

Tokopedia is one of the leading e-commerce platforms in Indonesia. The use of e-commerce platforms has increased rapidly in recent years. This is due to technological advances, increased internet access, and consumer behavior that prefers to shop online. In today's digital era, user reviews have an increasingly important role in shaping consumer perceptions of a product or service. The purpose of this research is to conduct sentiment analysis on application performance based on user reviews of the Tokopedia application. Researchers made the decision to use sentiment analysis because it is the most suitable method for processing data sets. From 1019 Tokopedia user reviews on the Play Store that were collected, 176 positive reviews and 843 negative reviews were obtained. Then, the data is classified using the Naive Bayes and K-Nearest Neighbor algorithms, then optimized using Particle Swarm Optimization. The results of the research conducted obtained an accuracy of 76.30% for the Naive Bayes accuracy value without feature selection, 74.09% for Naive Bayes results using feature selection. Then the accuracy value obtained for K-Nearest Neighbor without feature selection is 83.10%, and with feature selection is 83.53%. From the results obtained, the effect of using Particle Swarm Optimization selection features on the two algorithms does not have a big impact, there is an insignificant change in accuracy and AUC values which in the Naïve Bayes algorithm actually decreases

Published: August 2023

One of the development orientations in Indonesia is to improve the welfare of society. Therefore, it is important to identify and understand the characteristics of community welfare in each province in order to determine effective and targeted development strategies. Cluster analysis is one of the analyses that can be used to group provinces in Indonesia that have homogeneous characteristics within a cluster. The partition method is the simplest and fundamental approach to cluster analysis, but it can only find clusters with spherical-shaped forms. On the other hand, DBSCAN is a density-based clustering algorithm that can be used to find clusters with arbitrary shapes. In this study, the performance of the K-Means, K-Medoids, and DBSCAN algorithms was compared using data that had been dimensionally reduced using the t-SNE method. The data used was the indicator data of community welfare in the year 2022. The evaluation results of clustering based on the highest Silhouette coefficient (0.917) and the lowest Davies-Bouldin index (0.089) indicate that the best clustering methods are K-Means and DBSCAN with parameters perplexity = 1, minPts = 2, and epsilon = 9. Both methods produce the same result, which is the formation of eight clusters.
Effects of mild hypothermia on the cerebral microvascular tone
Authors: Melnikova NN
Published: August 2023

Acute blood loss is associated with deterioration of blood circulation, including microcirculation. Clinical and experimental studies are focused on the search for the possibility of neutralizing the consequences of such impairment. The use of hypothermia is considered not only as a method to improve survival, but also as a method to improve cerebral microcirculation in hemorrhage. The study was aimed to assess the state of the rats’ cerebral arteries in cases of mild hypothermic exposure after acute moderate blood loss. The study involving anesthetized Wistar rats was performed by vital microscopy. We assessed the responses of pial arteries (initial diameter 10–40 µm) in animals cooled to the rectal temperature of 34 °С under conditions of hemodynamic stability and when simulating blood loss (20% of total blood loss) in normothermic animals and animals with mild hypothermia. The findings showed that 3.5 h of exposure were associated with vasoconstriction in animals of all studied groups. Hypothermic state of the body was associated with initial decrease in the diameter by 9% of the baseline (24.9 ± 0.9 µm to 22.7 ± 0.7 µm; p < 0.05) followed by restoration of the diameter after 2 h (to 25.7 ± 1.7; p > 0.05). Blood loss was associated with the decrease in the diameter of cerebral blood vessels by 20–25% within the first hour (23.4 ± 0.7 µm to 17.6 ± 1.1 µm; p < 0.001) and no subsequent restoration (the diameter was 16.7 ± 0.8 µm after 3.5 h of monitoring). When using hypothermia, vasoconstriction following blood loss was 8–10% in the first 45 min of monitoring (22.6 ± 1.3 µm to 20.3 ± 1.2 µm; p < 0.05), then the constriction decrease was observed (the diameter was 21.4 ± 1.4 µm after 3.5 h of monitoring). It was concluded that the use of mild hypothermia resulted in the reduced vasoconstrictor effect of moderate blood loss on the pial microvessels.

Abstract

The existing literature have used media messages as a proxy variable for investor sentiment, but they mainly classify sentiment into positive or negative categories based on the words used in news articles, without much attention to the degree of affirmative or doubtful conveyed by the words used. Thus, in addition to classifying news content into positive or negative sentiment, this study also measures the degree of affirmative or doubtful expressed in the news articles in order to achieve more accurate predictive results. The study converts qualitative text to two quantitative scores (sentiment ratio and affirmative ratio) and investigates the predictive ability of these two variables on stock index returns and volatility in Taiwan’s case. The empirical findings indicate that only affirmative ratio exhibits a significant and negative impact on the one-day ahead returns of the Taiwan Stock Exchange Capitalization Weighted Stock Index (TAIEX) and the Taiwan Stock Exchange Index Futures (FITX). Additionally, the volatility of returns in both future and spot markets is significantly influenced by both sentiment ratio and affirmative ratio.

Arranjos domiciliares e suas condições de moradia: O caso viçosense entre 2000 e 2010
Authors:   , Rezende Sofia Assunção
Published: August 2023

Valores e comportamentos sociais estão em constante transformação. Não é diferente com as famílias. É sabido que elas adotam outros formatos e, sobretudo, as novas gerações alteram mais rotineiramente suas composições familiares. Entretanto, quais as características que expressam cada um dos possíveis arranjos domiciliares? Além disso, onde esses mesmos indivíduos vivem? Assim, o objetivo principal do presente estudo é esclarecer as condições de moradia segundo arranjos domiciliares. Presumíamos que precariedades vinculadas ao domicílio - falta de esgotamento sanitário, abastecimento de água, energia elétrica, etc. - estavam mais atreladas a determinados arranjos domiciliares devido às suas próprias vulnerabilidades. Para tanto, nos limitamos ao município de Viçosa, sem deixar de lado comparações dos comportamentos ocasionalmente de acordo com outros recortes territoriais. Limitamo- nos aos Censos Demográficos de 2000 e 2010, a fim de tentar captar as tendências mais recentes. Tentamos evidenciar as similaridades e as diferenças entre os arranjos domiciliares segundo suas condições de moradia através de técnicas de agrupamento estatístico (Análise de Cluster). Os dados indicam que os arranjos domiciliares não são determinantes para entendermos a precariedade habitacional. Porém, questões de gênero e raça e, concomitantemente, escolaridade e renda, sim. Estas últimas combinadas as características dos próprios arranjos evidenciam que, sobretudo, famílias monoparentais e unipessoais chefiadas por mulheres negras de baixa renda e baixa escolaridade são as mais vulneráveis. Acreditamos que os resultados podem fornecer importantes insumos para a formulação de políticas públicas sociais e habitacionais em diferentes escalas. Palavras-chave: Arranjos Domiciliares.

Characterization of prophage-like elements in plant pathogenic Xanthomonas species
Authors:   , Ferreira Nataly Figueiredo
Published: August 2023

Bacteriophages are viruses that infect prokaryotes that are present in diverse environments. Prophages are bacteriophages with genome into the host genome and have been considered part of bacteria mobilome. For instance, bacteriophages may encode proteins that increase bacteria toxicity and virulence, confer genetic variability, and facilitate horizontal gene transfer, improving bacterial fitness. The Xanthomonas genus harbors many phytopathogenic bacteria that impair many crops worldwide. However, there is a scarcity of studies that describes bacteriophage distribution and diversity within this genus. Given this, our study aims to identify and characterize the presence of prophage-like elements in three species belonging to the Xanthomonas genus: X. axonopodis, X. campestris and X. citri. We found prophage-like sequences in 98% of the analyzed genomes, whereby more than one prophage-like was detected within the same bacterial genome, event denominated as polilysogen. The prophages-like from Xanthomonas spp. belonged to four viral families (Myoviridae, Siphoviridae, Podoviridae, Inoviridae), three families belonging to the Caudovirales order and one belonging to the Tubulavirales order (Inoviridae). Furthermore, many prophages-like harbored genes of putative bacterial origin, indicating horizontal gene transfer between the virus and host, such as genes encoding virulence factors. Taken together, these results indicated that prophages-like are widespread in Xanthomonas spp., influencing the genome diversity and fitness of these bacteria. Keywords: Bacteriophage. PHASTER.

The objective of this research is application of Gross National Happiness (GNH) framework, grounded in the principles of Buddhist economics, in the Eastern European sustainable development context, specifically in Slovakia. This studies aim is to investigate the possibility of applying GNH framework in Slovakian environment. The research is an experimental study about the evaluation of the happiness index of Slovakian employees and employers of SMEs in Slovakia, in Rožňava region. The sustainable development in the region is lowest in the country, its' characterized by high unemployment rate, tendency of emigration, low standard of living, and inadequate healthcare services. Data were collected through two quantitative questionnaires, adapted and supplemented versions of the original Bhutanese questionnaire. The sample comprised 315 employees and 50 organizations in Slovakia. A distinctive aspect of this survey is its consideration of the implications of artificial intelligence and technological advancements. The study investigates the ways in which artificial intelligence influences human well-being and perceptions of trust. The findings reveal a critically low happiness index in the Rožňava region, indicating a need for intervention. This study would like to be contribution to the existing and further research of sustainability, about possibility to apply GNH framework in European culture in context of social, ecological and economical sustainable development.
