Published: November 2024

Postpartum care at home is still common in some, including in Kupang Regency, East Nusa Tenggara (NTT) Province. many mothers in Kupang, postpartum care at home is not only practical but also part of a tradition that has been passed down from generation to generation. However, this choice can increase health risks without adequate medical support. Therefore, it is important to understand how local culture influences this decision so that solutions to improve maternal and infant health can be found.
This study examines the influence of local culture and traditions on mothers' decisions to choose postpartum care at home. Using a qualitative approach and ethnographic design, this study describes postpartum care practices in Kupang Regency. In-depth interviews were conducted with mothers undergoing postpartum care, traditional birth attendants, and health workers. Data were collected from August to October 2023 and analyzed using six steps of qualitative methods.
The study's results identified three local cultural themes that influence postpartum care at home: 1) Postpartum taboos, as well as postpartum care traditions; 2) Family support; and 3) Belief in traditional birth attendants. This practice hinders mothers from utilizing available health facilities. This study recommends cultural integration in health education programs, increased collaboration between medical personnel and traditional birth attendants, and policies that support culturally friendly health access.

The purpose of this research is to assess the Intelligence and Management Performance: An Interactive Role of Knowledge Sharing Culture in the Pharmaceutical Sector in KP. Using a cluster sampling method, the sample was taken from the population of the study, which consisted of all of the top management individuals working in the numerous pharmaceutical companies owned by KP. The findings of the study indicate that intelligence has a significant relationship with managerial performance. Furthermore, the culture of knowledge-sharing moderates the relationship between emotional intelligence and managerial performance. Furthermore, such a culture also moderates the relationship between cultural intelligence and managerial performance. Additionally, it does not moderate a significant association between social intelligence and cognitive intelligence with the relationship of managerial performance. This is the case because it does not moderate the relationship.

The Philosophical Thoughts of Vajiravudh: A Dialogical Analysis from the Perspective of Critical Filipino Philosophy
Authors:   De La Salle University Manila, Demeterio III F.P.A.
Published: November 2024

Vajiravudh (1881-1925), or King Rama VI of Siam, son of Chulalongkorn (King Rama V) and brother of Prajadhipok (King Rama VII), was a writer, nationalist, reformist, known as the Maha Thiraraja (philosopher king), and a creative genius among the Thai people. His context of a semi-colonial country that was pressured to embrace globalization and modernization still resonates with the conditions of some parts of Southeast Asia, such as the Philippines. This paper explored his philosophical ideas from the point of view of critical Filipino philosophy, a family of discourses that can be traced back to the musings of the late 19th century Filipino propagandists, with the intention of gleaning meaningful lessons for the contemporary Filipino people. Specifically, this paper looked into Vajiravudh’s thoughts on nationalism and identity, the Chinese and Muslim minorities, modernization and international relations, politics, gender, and family, as well as on his use of literature in philosophizing. This paper is significant in building up the literature on comparative Southeast Asian philosophy.

Discourses in school algebra: the textbooks’ different views on algebra and the positioning of students
Authors: Palm Kaplan Kristina
Published: November 2024

The purpose of this study is to understand the school algebra offered in Swedish mathematic textbooks for grade 8. Using a social semiotic perspective, textbook tasks are analysed with a method inspired by Systemic Functional Linguistics. Five school algebra discourses are identified: symbolic discourse, geometrical discourse, arithmetical discourse, (un)realistic discourse and the scientific discourse. It is argued that these offer different views on the nature of algebra and the positioning of students.
The gap between school mathematics and university mathematics: prospective mathematics teachers’ conceptions and mathematical thinking
Authors: Hannula Jani
Published: November 2024

In Finland, both prospective and in-service mathematics teachers report a discontinuity between university-level mathematics and mathematics taught at comprehensive and secondary school. In this study, ten prospective mathematics teachers (PMTs) were interviewed to examine their conceptions of the nature of this gap as well as their mathematical thinking. The study’s findings support research that has revealed difficulties experienced by PMTs in the secondary–tertiary transition and in connecting formal and informal components of mathematical thinking. Additionally, the study provides new insight into PMTs’ conceptions of teacher knowledge, such as the relationship between knowledge of advanced mathematics and the knowledge needed in teaching situations. The findings offer guidelines for further studies that could help the development of mathematics teacher education.
Fabrication of newly-arrived students as mathematical learners
Authors: Norén Eva , Svensson Källberg Petra
Published: November 2024

As a response to recent laws on how to support newly-arrived students’ schooling, new policy texts have been released in Sweden. By analyzing policy texts we show how a particular kind of human, ”the newly-arrived student as a mathematical learner” is fabricated through discursive processes. We show how the policy texts are framed within an including discourse that encourages multiculingualism and views students’ mother tongue and backgrounds as resources. However, simultaneously the newly-arrived student is thought of, in a more excluding discourse, as being in need of rescue and as lacking the most valuable asset, the Swedish language.

Engaging children in mathematical discourse: a kindergarten teacher’s multimodal participation
Authors: Breive Svanhild
Published: November 2024

This article reports from a case study which investigates a kindergarten teacher’s multimodal participation in a teaching-learning activity involving addition and counting. By multimodal participation the kindergarten teacher engages nine children (age 4.9–5.9) in mathematical discourse and supports their opportunities for learning. Implications for practice are that kindergarten teachers (and school teachers) can benefit from being consciously aware of the affects their bodily actions have on children’s mathematical reasoning and how they can engage children in mathematical discourse without having to ”teach” (i.e., tell) children mathematical concepts and relations. The article also considers how kindergarten teachers can prepare for a smooth transition to school by introducing children to mathematics through semi-structured activities.
Studenters forestillinger, holdninger og følelser overfor matematikk
Authors: Svege Elna
Published: November 2024

Som hovedfagsstudent i matematikkdidaktikk ved Høgskolen i Agder skrev jeg i 1995/1996 hovedfagsoppgaven: "Affektive sider ved studenters læring og undervisning av matematikk" (Svege, 1996). En del av denne oppgaven var et forsøk på å kartlegge noen av studentenes forestillinger, holdninger og følelser til matematikk når de begynner på en høgskole.
Denne artikkelen er en kort presentasjon av det affektive området, samt noen av de resultatene som kom fram av en spørreundersøkelse, og en diskusjon av disse resultatene. Spørreundersøkelsen viste blant annet at de fleste studentene:

– definerer matematikk primært som regning med tall ved hjelp av de fire regningsarter

– mener at matematikk stort sett består av fakta og fremgangsmåter som må læres utenat
– ser på matematikk som et statisk fag som er fast og forutbestemt, der det er få muligheter til å gjøre forandringer
– mener de har små muligheter til å oppdage ting selv, siden det meste allerede er utforsket og oppfunnet av matematikerne
– mener at noen er født med anlegg for matematikk, men alle med vanlige evner kan lære seg matematikk
– mener at de ikke kan lære seg matematikk på egenhånd, men er avhengig av en autoritet til å fortelle dem hva som er riktig og galt
– mener at det er bare ett riktig svar på problemer, men flere fremgangsmåter for å komme fram til det riktige svaret
– mener at det er viktig å reflektere over hvorfor fremgangsmåter virker og hvorfor svaret er riktig, men dette følges ikke alltid opp i praksis
– er enig i at matematikk kan være gøy
– studerer matematikk fordi det er en del av studiet, men også fordi matematikk er nyttig i andre fag og i senere jobb
– ser på matematikk som et viktig fag
– legger mest vekt på den profesjonelle siden av lærergjerningen framfor mer affektive sider, når de skal karakterisere en god lærer

En av tre studenter mener matematikk er kjedelig og en av fem studenter får panikk når de blir konfrontert med en matematikkoppgave.

El lugar del romancero de historia antigua en el canon del siglo XVI
Authors: Higashi Alejandro
Published: November 2024

En el presente estudio, se muestra la trayectoria editorial del romancero de historia antigua, desde el análisis de las etiquetas de género poco delimitadas y tendientes a desvalorizarlo hasta su dignificación como género serio, con un trasfondo histórico, poder divulgativo y respaldo en fuentes documentales. Para ello, se analizan las estrategias editoriales presentes en los proyectos más importantes del quinquenio 1546-1551 (el Cancionero de romances, de Martín Nucio; la Silva de varios romances, de Esteban de Nájera; los Romances nueuamente sacados de historias antiguas dela cronica de España, de Lorenzo de Sepúlveda y los Quarenta Cātos de diuersas y peregrinas historias, de Alonso de Fuentes), así como las trayectorias de lectura, líneas temáticas y posibilidades interpretativas que resultaron de cada proyecto. El análisis comparativo de los romanceamientos de las traducciones de obras eruditas y clásicas permitió identificar otras estrategias compositivas y prestigiosas que colocaron al romance de historia antigua en el mismo nivel que sus fuentes. Finalmente, se describe el esfuerzo de los humanistas por dignificar el subgénero, desde la vinculación de éste con otros prestigiosos hasta su comparación con otros hechos históricos que evidencian su valor de verdad y de perpetuación de la memoria histórica.

Este trabajo presenta, como objetivo fundamental, la edición crítica de La Coronación de Nuestra Señora (0116), de Fernán Ruiz de Sevilla, un poema recogido en el Cancionero de Llavia y en el manuscrito PN6. El estudio ecdótico de esta obra se relaciona, también, con una versión tardía, la Nueva Coronación, impresa en un pliego del siglo xvi y que introduce importantes elementos paratextuales, así como numerosas variantes respecto de los otros dos testimonios. Por ello, realizamos, también, la edición crítica de esta Nueva Coronación, en tanto que debe ser considerada como un testimonio único. No obstante, el análisis ecdótico y el cotejo de las lecciones nos permitirá arrojar luz sobre la posible filiación o antecedente común que el impreso del siglo xvi comparte con PN6.
Acoustic radiation force of a free spherical particle in a bounded viscous fluid

The manipulation of particles by acoustic radiation force (ARF) has the advantages of non-invasiveness, high biocompatibility, and wide applicability. The study of acoustic radiation force is an important foundation for improving the accuracy and effectiveness of particle manipulation technology. Based on the acoustic wave theory, a theoretical model for the ARF of a free spherical particle in a bounded viscous fluid is established. The ARF for the case of a normal incident plane wave is derived by applying the translation addition theorem to spherical function. The dynamic equation of a free sphere is required as a correction term for calculating the ARF. The effects of the fluid viscosity, particle material, particle distance from boundary, and the boundary on the ARF are analyzed by numerical simulation. The results show that the resonance peak of the ARF curve is broadened with the increase of the viscosity of the fluid. Compared with the values of the ARFs of a PE sphere in a viscous and an ideal fluid, the fluid viscosity has a small influence and the viscosity effect can be ignored when kR is much less than 1. However, for the cases where kR is greater than or equal to 1, the amplitude of the ARF experienced by a particle in a viscous fluid is much greater than that in an ideal fluid. The influence of fluid viscosity on the ARF is significant and cannot be ignored. Moreover, compared with a liquid material sphere, the oscillation of ARF in an elastic material sphere is more pronounced. This is because the momentum transfer between sound waves and elastic materials is greater than that between sound waves and liquid materials. In addition, the amplitude of the ARF increases with the increase of the reflection coefficient of the impedance boundary, but its resonance frequency is not affected. Finally, the position of the sphere mainly affects the oscillation phenomenon of its ARF. The peaks and dips of the ARF become more densely packed with the growth of distance-to-radius. It is worth noting that the reflection coefficient mainly affects the amplitude of the ARF, while the position of the sphere affects the period of the ARF function. The results indicate that more efficient manipulation of particles can be achieved through appropriate parameter selection. This study provides a theoretical basis for acoustically manipulating a free particle in a bounded viscous fluid and contributes to the better utilization of ARF for particle manipulation in biomedical and other fields.
The evolutionary modifications of a GoLoco motif in the AGS protein facilitate micromere formation in the sea urchin embryo

Published: November 2024

The evolutionary introduction of asymmetric cell division (ACD) into the developmental program facilitates the formation of a new cell type, contributing to developmental diversity and, eventually, to species diversification. The micromere of the sea urchin embryo may serve as one of those examples: An ACD at the 16-cell stage forms micromeres unique to echinoids among echinoderms. We previously reported that a polarity factor, Activator of G-protein Signaling (AGS), plays a crucial role in micromere formation. However, AGS and its associated ACD factors are present in all echinoderms and across most metazoans. This raises the question of what evolutionary modifications of AGS protein or its surrounding molecular environment contributed to the evolutionary acquisition of micromeres only in echinoids. In this study, we learned that the GoLoco motifs at the AGS C-terminus play critical roles in regulating micromere formation in sea urchin embryos. Further, other echinoderms’ AGS or chimeric AGS that contain the C-terminus of AGS orthologs from various organisms showed varied localization and function in micromere formation. In contrast, the sea star or the pencil urchin orthologs of other ACD factors were consistently localized at the vegetal cortex in the sea urchin embryo, suggesting that AGS may be a unique variable factor that facilitates ACD diversity among echinoderms. Consistently, sea urchin AGS appears to facilitate micromere-like cell formation and accelerate the enrichment timing of the germline factor Vasa during early embryogenesis of the pencil urchin, an ancestral type of sea urchin. Based on these observations, we propose that the molecular evolution of a single polarity factor facilitates ACD diversity while preserving the core ACD machinery among echinoderms and beyond during evolution.

Sensory dorsal root ganglion (DRG) neurons have a unique pseudo-unipolar morphology in which a stem axon bifurcates into a peripheral and a central axon, with different regenerative abilities. Whereas peripheral DRG axons regenerate, central axons are unable to regrow. Central axon regeneration can however be elicited by a prior conditioning lesion to the peripheral axon. How DRG axon asymmetry is established remains unknown. Here we developed a rodent in vitro system replicating DRG pseudo-unipolarization and asymmetric axon regeneration. Using this model, we observed that from early development, central DRG axons have a higher density of growing microtubules. This asymmetry was also present in vivo and was abolished by a conditioning lesion that decreased microtubule polymerization of central DRG axons. An axon-specific microtubule-associated protein (MAP) signature, including the severases spastin and katanin and the microtubule regulators CRMP5 and tau, was found and shown to adapt upon conditioning lesion. Supporting its significance, interfering with the DRG MAP signature either in vitro or in vivo readily abolished central-peripheral asymmetries in microtubule dynamics and regenerative ability. In summary, our data unveil that axon-specific microtubule regulation drives asymmetric regeneration of sensory neuron axons.

Two distinct classes of antibiotics elicited remarkably similar responses and increased flux through the TCA cycle, causing enhanced respiration, ROS generation, and ATP burst. We observed that excessive ATP levels and not ROS, dominantly contributes to cidality, which may in part be, conferred by sequestration of divalent metal ions by ATP. Consequently,

C isotope tracing indicated TCA cycle flux deviation from its oxidative arm as a bacterial adaptive mechanism, which also included activated intrinsic resistance and a higher propensity to develop antibiotic resistance.

Insights into Spanish metrical structure through language games
Authors: Fonseca Quesada Felix
Published: November 2024

Some Spanish language games involve reordering the syllables of the words. However, the stressed syllable of the game word does not always match the stressed syllable in the original Spanish word and/or the position of the stress in the original Spanish word. Using game words found in different sources, a corpus of 261 words from different Spanish games was created to account for the games’ stress patterns. The metrical structure of the language games (e.g., Vesre, which is a game in Argentina and Uruguay) was analyzed. The results of the analysis suggest that the game words’ metrical structures are composed of quantity-sensitive, right-aligned trochee, in which the stress falls in penultimate position in vowel-final words, and consonant-final words generally have final stress, confirming previous proposals about the default metrical structure of Spanish (Harris, 1983; Núñez-Cedeño and Morales-Front, 1999). Overall, these Spanish language games illustrate The Emergence of The Unmarked (TETU) in metrical structure, providing evidence of Spanish stress assignment, whereby the unmarked stress pattern is a right-aligned quantity-sensitive trochee.
cortesía retrogratificadora en las felicitaciones de logros de los personajes influyentes españoles en Instagram
Authors: Porrino Moscoso Laura María
Published: November 2024

Actualmente, Instagram es la red preferida por los usuarios, los creadores de contenido y las empresas (Kemp 2024: 277-280) para comunicarse con su audiencia. Entre los contenidos que más publican los internautas destacan las felicitaciones, que son actos expresivos de cortesía positiva que buscan gratificar la imagen del destinatario. A pesar de ello, todavía no hay investigaciones cortesiológicas que aborden su estudio. El objetivo del presente trabajo ha sido examinar cómo es la cortesía retrogratificadora o valorizante que los personajes públicos influyentes españoles de Instagram emplean al realizar felicitaciones de logros profesionales a personas cercanas, y cómo son las estrategias corteses que los amigos y los familiares de los creadores utilizan cuando comentan.
Para ello, se tomaron como base los principales modelos cortesiológicos que tratan la imagen (Brown y Levinson (1978, 1987; Kerbrat-Orecchioni 1992, 1996) y la taxonomía de respuestas a felicitaciones de Elwood (2004), y se aplicaron al análisis sociopragmático de un corpus de felicitaciones de conocidos creadores de Instagram. Los resultados mostraron que, además de las felicitaciones, estos incluían en sus contenidos y en sus comentarios, sobre todo, muestras de afecto, elogios y afirmaciones. Los comentadores, en lugar de felicitar, preferían mostrar afecto, elogiar y aplaudir la buena noticia. A su vez, tanto autores como comentadores reforzaban sus intervenciones con diversos mecanismos de intensificación de cortesía retrogratificadora, principalmente lexemas con sema de intensidad y repeticiones de emojis. Igualmente, se observó que los emojis son una pieza imprescindible para expresar cortesía retrogratificadora en las felicitaciones de logros.
EFR-FCOS: enhancing feature reuse for anchor-free object detector
Authors: Liao Yongwei , Li Zhenjun , Feng Wenlong , Zhang Yibin , Zhou Bing
Published: November 2024

In this paper, we propose enhancing feature reuse for fully convolutional one-stage object detection (EFR-FCOS) to aim at backbone, neck and head, which are three main components of object detection. For the backbone, we build a global attention network (GANet) using the block with global attention connections to extract prominent features and acquire global information from feature maps. For the neck, we design an aggregate feature fusion pyramid network (AFF-FPN) to fuse the information of feature maps with different receptive fields, which uses the attention module to extract aggregated features and reduce the decay of information in process of the feature fusion. For the head, we construct a feature reuse head (EnHead) to detect objects, which adopts the cascade detection by the refined bounding box regression to improve the confidence of the classification and regression. The experiments conducted on the COCO dataset show that the proposed approaches are extensive usability and achieve significant performance for object detection.
Optimizing 5G network performance with dynamic resource allocation, robust encryption and Quality of Service (QoS) enhancement

Published: November 2024

The International Telecommunication Union (ITU) predicts a substantial and swift increase in global mobile data traffic. The predictions suggest that this growth will vary from 390 EB (exabytes) to 5,016 EB (exabytes) from 2024 to 2030, accordingly. This work presents a new maximum capacity model (MCM) to improve the dynamic resource allocation, robust encryption, and Quality of Service (QoS) in 5G networks which helps to meet the growing need for high-bandwidth applications such as Voice over Internet Protocol (VoIP) and video streaming. Our proposed MCM model enhances data transmission by employing dynamic resource allocation, prioritised traffic management, and robust end-to-end encryption techniques, thereby guaranteeing efficient and safe data delivery. The encryption procedure is applied to the header cypher, while the output parameters of the payload are altered. This indicates that only the sender and recipient will possess exclusive knowledge of the final outcome. In result, the comparative analyses clearly show that the MCM model outperforms over conventional models in terms of QoS packet planner, QoS packet scheduler, standard packet selection, traffic management, maximum data rate, and bandwidth utilisation.
Genome-wide identification of the Gossypium hirsutum CAD gene family and functional study of GhiCAD23 under drought stress

Published: November 2024

Cinnamyl alcohol dehydrogenase (CAD) is a crucial enzyme in the final stage of lignin monomer biosynthesis. This study focuses on the CAD gene family within Gossypium hirsutum. Through comprehensive genomic analysis, we identified 29 GhiCAD genes within the Gossypium hirsutum genome using a bioinformatics approach. Phylogenetic analysis revealed that the GhiCAD family can be categorized into four subgroups, which are closest to the evolutionary relationship with Arabidopsis thaliana. There are multiple cis-acting elements on the promoters of GhiCAD genes associated with abiotic stress responses. Some GhiCAD genes demonstrated high expression in various tissues like root, leaf, and sepal, as well as in fiber and ovule at different developmental stages (10 days post anthesis (DPA), 15 DPA, 20 DPA, 25 DPA). The transcript levels of GhiCAD23 were notably elevated when exposed to PEG treatment and drought stress (DS). GhiCAD23 is also co-expressed with many known drought response genes, suggesting its involvement in the plant’s reaction to DS. Employing virus-induced gene silencing (VIGS) technology to silence the GhiCAD23 gene, it was found that silencing GhiCAD23 reduced the tolerance of cotton to DS. Under DS, the relative leaf water content, superoxide dismutase (SOD), and catalase (CAT) enzyme activities of the GhiCAD23-silenced cotton plants were decreased by 31.84%, 30.22% and 14.19%, respectively, while malondialdehyde (MDA) was increased by 72.16% compared with the control cohort. Drought promotes the accumulation of lignin, and it was found that silencing the GhiCAD23 reduces lignin accumulation in cotton under DS. The analysis of phenotypic and physiological indicators indicates that GhiCAD23 is vital in cotton’s resistance to DS. This investigation provides an important reference for future comprehensive exploration of the GhiCAD23 gene’s function in cotton’s DS response mechanism.
The effect of carbonic anhydrase on foraminiferal Mg/Ca

Published: November 2024

Marine biogenic calcium carbonate production plays a role in the exchange of CO2 between ocean and atmosphere. The effect of increased CO2 on calcification and on the resulting chemistry of shells and skeletons, however, is only partly understood. Foraminifera are among the main marine CaCO3 producers and the controls on element partitioning and isotope fractionation is the subject of many recent investigations. The enzyme carbonic anhydrase (CA) was, for example, shown to be vital for CaCO3 deposition in benthic foraminifera and indicates their ability to manipulate their intracellular inorganic carbon chemistry. Here, we tested whether CA affects the partitioning of Na, Mg and Sr in the perforate, large benthic, symbiont-bearing foraminifer Amphistegina lessonii by addition of the inhibitor acetazolamide (AZ). The effect of dissolved CO2 on the effect of CA on element partitioning was also determined using a culturing setup with controlled atmospheric carbon dioxide levels (400–1,600 ppm). Results show that inhibition by AZ reduces calcification greatly and that CO2 has a small, but positive effect on the amount of calcite formed during the incubations. Furthermore, the inhibition of CA activity has a positive effect on element partitioning, most notably Mg. This may be explained by a (n indirect) coupling of inorganic carbon uptake and inward calcium ion pumping.

Background

The species Cupressus funebris holds substantial ecological value and economic potential, particularly in the realms of rehabilitating barren mountain landscapes and advancing urban greening endeavors. However, inadequate attention has been given to research endeavors exploring the genetic diversity and morphological characteristics of Cupressus funebris, a deficiency that could potentially hinder its development, utilization, and conservation of genetic resources.

Methods

To rectify the shortage of existing basic morphological data, a morphological analysis was conducted in this study on 180 Cupressus funebris germplasm resources sourced from five provenances. Key traits explored included growth characteristics, overall morphology, branch/leaf features, and seed traits. This will facilitate the evaluation of genetic diversity in Cupressus funebris.

Results

The findings reveal a considerable level of phenotypic variation (PVC of 16.9%) and genetic diversity (1.97 index) in Cupressus funebris germplasm resources. The phenotypic differentiation is observed to be 48% between provenances and 52% within provenances, primarily attributed to variation originating from individual provenances. Based on these morphological characteristics, the germplasm resources have been categorized into four distinct groups: Ecological Restoration Planting, Secondary Reserve Forest, Urban Greening, and Timber Forest. Interestingly, the pattern of variation observed within these groups is irregular, exhibiting no significant correlation with their respective provenances. Furthermore, conifer trees sharing similar growth characteristics tend to display comparable patterns of random variation, suggesting potential underlying genetic mechanisms. This study significantly enriches the phenotypic dataset within the genetic variation research of Cupressus funebris, facilitating development and utilization for ecological construction, timber breeding, and horticultural greening.
Resistance characterization and transcriptomic analysis of imipenem-induced drug resistance in Escherichia coli
Authors: Tong Chunyu , Liang Yimin , Liu Qi , Yu Honghao , Feng Wenzhi , Song Bocui
Published: November 2024

Background

Bacteria can develop resistance to various antibiotics under selective pressure, leading to multifaceted changes in resistance mechanisms. Transcriptomic sequencing allows for the observation of transcriptional level alterations in cells under antibiotic stress. Understanding the bacterial response to such stress is essential for deciphering their strategy against drug-resistant antibiotics and identifying potential targets for antibiotic development.

Methods

This study using wild-type (WT) Escherichia coli (E. coli) discovered that continuous in vitro induction screening for imipenem-resistant strains resulted in bacteria with enhanced biofilm-forming ability and mutations in antibiotic target sites. Transcriptomic sequencing of the resistant bacteria revealed significant changes in carbon and amino acid metabolism, nutrient assimilation, substance transport, nucleotide metabolism, protein biosynthesis, and cell wall biosynthesis. The up-regulated drug efflux genes were disrupted using gene knockout technology. Drug sensitivity tests indicated that drug efflux has a minimal effect on imipenem resistance.

Results

This suggests a strategy for E. coli drug resistance involving the reduction of unnecessary substance synthesis and metabolism, coupled with an increase in activities that aid in resisting foreign threats.

Published: November 2024

Background

Exercise in humid and hot environments (HHEs) may result in decreased perception, motor performance, and memory owing to endogenous heat production and exogenous load. However, whether a single bout of exercise (SBOE) intensity affects the magnitude of changes in the levels of hemocytes remains controversial. In this article, we aimed to investigate the effects of a SBOE of varying intensities on blood cells in HHE.

Methods

Thirty-two volunteers were randomly divided into a quiet control group (QC), 55% VO2max intensity exercise group (HHE55%), 70% VO2max intensity exercise group (HHE70%), and 85% VO2max intensity exercise group (HHE85%). The participants in the exercise groups were assigned to perform an SBOE on the treadmill under HHE conditions for 30 min, whereas participants in the QC remained still under HHE conditions for 30 min (temperature: 28–32 °C, relative humidity: 85–95%).

Results

The net body mass (NBM), perfusion index (PI), mean corpuscular volume (MCV), platelet (PLT), and plateletcrit (PCT) values were affected significantly by the exercise intensity (P < 0.01) the hemoglobin (HGB) and neutrophil count (NE) were affected significantly by exercise intensity (P < 0.05). After an SBOE, compared with that before exercise, the sublingual temperature (ST) of all groups, the NBM and MCV of all exercise groups, the PI of the HHE55% and HHE70% groups, the HGB, hematocrit (HCT), and NE of the HHE70% group, the red blood cell count (RBC), PLT, and PCT of the HHE70% and HHE85% groups, and the white blood cell count (WBC) of HHE85% changed very significantly (P < 0.01). The PCT of QC, blood oxygen saturation (SaO2), and soluble transferrin receptor (sTfR) levels in the HHE55% group, the lymphocyte count (LY) in the HHE70% group, and the HGB and HCT in the HHE85% group changed significantly (P < 0.05).

Conclusion

Low- and moderate-intensity SBOE in HHE could increase the serum EPO and serum sTfR levels and decrease the serum IL-3 levels. Conversely, a high-intensity load could increase the risk of inflammation. Therefore, low-intensity exercise may be more appropriate for an SBOE in HHE.
Vascular synovial phenotype indicates poor response to JAK inhibitors in rheumatoid arthritis patients: a pilot study
Authors: Liu Mengxia , Liu Pengcheng , Li JianBin , Huang Yiping , Wu Rui
Published: November 2024

Objective

Rheumatoid arthritis (RA) is a chronic autoimmune inflammatory disease, characterized by significant individual variations in treatment response. Predicting treatment response remains a formidable challenge. This study aims to identify predictors within the synovium associated with the response to JAK inhibitor therapy in RA patients, employing a retrospective approach.

Methods

A retrospective analysis was conducted on 27 RA patients who underwent synovial biopsy and received JAK inhibitor therapy for at least three months at our center, from January to November 2023. These patients had comprehensive clinical records. Based on their response to JAK inhibitor therapy, as measured by the ACR20 criteria, they were categorized into non-responder and responder groups. We compared clinical data (including sex, age, disease duration), laboratory findings (RF, ACPA, ESR, CRP, etc.), DAS28-CRP scores, and synovial pathology features—such as synovial lining hyperplasia, neovascularization, stromal activation, inflammatory infiltration, and the expression of CD3, CD20, CD68, and CD138 markers in the synovium—between the two groups.

Results

The rate of non-responder to JAKi was found to be 33.3% (nine cases out of a total of 27 patients). Non-responders, when compared to responders, exhibited longer disease duration, more pronounced synovial neovascularization alongside reduced infiltration of labeled CD20+ and CD138+ cells in the synovium. Multivariate regression analysis identified synovial neovascularization and disease duration as independent predictors of a poor response to JAK inhibitor treatment.

Conclusions

The presence of vascular phenotype with low inflammation within the synovium of RA patients is an indicator of poor response to JAK inhibitor therapy, highlighting its potential as a predictive marker for treatment outcomes.

Exploring the Impact of Organizational Structure on the Role of Local Government Communication Officers in Tanzania: A Qualitative Study
Authors: Kazinja Deodatus Galeba
Published: November 2024

The significance of the roles played by communication officers in ensuring organisational success cannot be overstated, yet these professionals may face obstacles in large organisations due to structural factors. This study aimed to identify the impact of organisational structure to the functions of communication staff at local authorities in five municipal councils within Dar es Salaam City, Tanzania. A qualitative research approach was employed, with purposive sampling used to select 14 respondents, consisting of nine communication officers and five executive directors. Data was collected through in-depth interviews, observations, and document reviews. Thematic analysis was used to analyse the collected data. The study's findings revealed that the primary challenge faced by communication staff in Dar es Salaam city was the independence of the communication unit, leading to secondary issues such as budget constraints and subpar working environments. The study concludes that, due to the lack of autonomy in the communication unit, communication activities were primarily technical rather than management functions, as communication officers were not involved in decision-making meetings where key decisions about the councils were made. The study recommends that local councils in Tanzania should improve their organisational structure to allow communication officers to be members of the Council Management Team (CMT), thereby aligning communication activities with the overall strategic plan of the councils.
