The mechanism of fluorescence quenching of naphthalimide A/C leak detector by copper (II)
Authors: Badran Ismail , Riyaz Najamus Sahar
Published: July 2023

Background

Fluorescence quenching is an interesting phenomenon with the potential to be applied across various fields. The mechanism is commonly used across analytical applications for monitoring the concentration of trace substances. Naphthalimide and its family of compounds are commonly used as fluorescent detectors. This work investigated an analytical technique through which naphthalimide-based dyes could be quantified. A commercial A/C leak detector was used as the dye and Cu2+ ions as the quencher. Experiments were also conducted to investigate the effect of temperature on quenching. To study the mechanism of quenching further, density functional theory (DFT) was used.

Results

The method detection limit obtained in this work is 1.7 × 10–6 mol/L. The results from the quenching experiments demonstrated a pattern which fit a modified Stern–Volmer (SV) model, with an R2 value of 0.9886. From the experiments on the effect of temperature, a dynamic quenching behavior was observed given the emission spectra demonstrated an inverse relationship with temperature.

Conclusions

The quenching of the commercial A/C dye by Cu2+ ions can be used to develop a rapid and sensitive detection method for metal ions such as Cu2+, and for future fabrication of chemosensors for Cu2+.
PyGellermann: a Python tool to generate pseudorandom series for human and non-human animal behavioural experiments
Authors: Jadoul Yannick , Duengen Diandra , Ravignani Andrea
Published: July 2023

Objective

Researchers in animal cognition, psychophysics, and experimental psychology need to randomise the presentation order of trials in experimental sessions. In many paradigms, for each trial, one of two responses can be correct, and the trials need to be ordered such that the participant’s responses are a fair assessment of their performance. Specifically, in some cases, especially for low numbers of trials, randomised trial orders need to be excluded if they contain simple patterns which a participant could accidentally match and so succeed at the task without learning.

Results

We present and distribute a simple Python software package and tool to produce pseudorandom sequences following the Gellermann series. This series has been proposed to pre-empt simple heuristics and avoid inflated performance rates via false positive responses. Our tool allows users to choose the sequence length and outputs a .csv file with newly and randomly generated sequences. This allows behavioural researchers to produce, in a few seconds, a pseudorandom sequence for their specific experiment. PyGellermann is available at https://github.com/YannickJadoul/PyGellermann.
Carnivoran fossils from the Pampean region (Argentina): Santiago Roth collections in Switzerland
Authors: Ruiz-Ramoni Damián , Carrillo‑Briceno Jorge D. , Voglino Damian , Prevosti Francisco Juan
Published: July 2023

Santiago Roth (1850–1924) was a naturalist that collected and sold fossils from the Pampean region (Argentina) in Europe. Much of the specimens collected by Roth are hosted at the Paläontologisches Institut und Museum, Universität Zürich and Muséun D’Histoire Naturelle of Geneva in Switzerland, but were never studied. In this article, we review the specimens of the order Carnivora under a taxonomical and temporal approach. We confirm the presence of 16 specimens of Carnivora collected by Roth between the provinces of Santa Fe and Buenos Aires. We identify felids (Smilodon sp., Panthera onca, and specimens related to these taxa), ursids (Arctotherium sp.), and canids (Dusicyon avus and specimens related, Lycalopex sp., and Caninae indet.). According to the information reported by S. Roth, all materials are from the Pleistocene of the Pampean Formation. However, given the scarcity of data, only the specific age of few specimens could be more accurately established.

Authors: Jiménez-Hernández Héctor Adrián , Bonilla-Valencia Leticia , Martínez-Orea Yuriana , Zamora-Almazan Mara Jessica , Espinosa-García Francisco Javier , Castillo-Argüero Silvia
Published: July 2023

Background

Hederahelix L. is an invasive weed species introduced in several regions of the world, so it is relevant to study its effects on the plant community and the changes occurring after its eradication. We established invaded (with/without removal of H. helix) and non-invaded (with/without removal of the understory) plots to compare some community attributes in an oak forest in Mexico City and monitored them every 2 months for 1 year, taking soil samples to compare some edaphic variables between the plots. If invasive species negatively affect natural regeneration, seedlings of native species would be less abundant in plots invaded by H. helix than in the non-invaded ones. As invasive species modify the soil microbiota through exudates and often allelochemicals, soil chemical variables would differ between invaded and non-invaded plots.

Results

The abundance of native species was lower in the invaded plots, but the richness and diversity of species were not statistically different. The composition of the two invaded plots was similar to each other and more alike to that of the non-invaded plots. The species composition of the invaded plots was associated with soil potassium and phosphorus concentrations, whereas that of the non-invaded plots was more associated with soil nitrogen concentration.

Conclusions

Following the removal of H.helix, several native species were registered, leading to a similar species composition as in the non-invaded plots, suggesting that some vegetation recovery can be expected following H. helix removal in 1 year.
Performance of commercial growing-finishing pigs fed supplemental isoquinoline alkaloids: a statistical process control analysis
Authors: Artuso-Ponte V. , Steiner T. , Neher F. , Cano Emilio L. , Morillo-Alujas A.
Published: July 2023

Background

Statistical Process Control (SPC) is a powerful statistical tool that can be used in animal production to evaluate the evolution of production parameters overtime in response to the implementation of a specific strategy. The aim of this study was to evaluate the effect of supplementing growing-finishing pigs with isoquinoline alkaloids (IQ) on growth performance parameters by using the SPC method. IQ are natural secondary plant metabolites which have been extensively investigated in food animals due to their efficacy in supporting growth performance and the overall health status. Performance parameters and medication usage were collected from 1,283,880 growing-finishing pigs fed the same basal diet, 147,727 of which were supplemented with IQ from day 70 of life until slaughter.

Results

Supplementation with IQ improved feed conversion ratio, while feed intake and daily gain were maintained.

Conclusion

SPC methods are useful statistical tools to evaluate the effect of using a new feed additive in the feed of pigs on growth performance at a commercial level. Additionally, IQ supplementation improved growth performance and it can be considered as a good strategy to reduce feed conversion in growing-finishing pigs.

Authors: Zaki Maha Atef , Abdelalim Ahmed Mohamed , Mourad Husam Salah , Saad Abdallah Adel , Fouad Amr Mohamed
Published: July 2023

Background

A wide variety of factors have been reported to influence stroke prognosis. Quality indicators serve as standards of care. The aim of this study is to assess the clinical and demographic characteristics of patients with stroke and to measure quality indicators in relation to stroke early outcome. We analyzed a prospective hospital-based data. All patients with acute stroke admitted to Kasr-al-ainy stroke unit over a 1-year period were included. Clinical variables and quality indicators were studied in relation to early outcome which was measured by both disability at discharge assessed by modified Rankin score (mRS) and in-hospital death.

Results

We studied 242 patients with acute stroke, 145 patients (59.9%) had poor outcome at discharge [mRS 3–6]. There were 36 (14.9%) in-hospital deaths. High mRS and National institute of health stroke scale (NIHSS) at stroke onset, low Gugging swallowing scale (GUSS) score and hypertension (HTN) were independent predictors for more disability on discharge. Chest infection, bed sores, high mRS at stroke onset and hemorrhagic transformation were independent predictors for in-hospital mortality. Receiving recombinant tissue plasminogen activator (rtPA) showed significant association with good outcome. Mean door to needle time (DNT) was 50.6 min. Low GUSS score was associated with increased risk of chest infection.

Conclusions

Stroke severity, potentially modifiable risk factors and complications are associated with an increased risk of poor early outcome. Dysphagia screening using GUSS scale can predict patients with higher risk of aspiration pneumonia after stroke. DNT needs to be improved.
Sequencing of Endocrine and Targeted Therapies in Hormone-Sensitive, Human Epidermal Growth Factor Receptor 2–Negative Advanced Breast Cancer
Authors: Jackson Emily B. , Chia Stephen K.L.
Published: July 2023

The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology , to patients seen in their own clinical practice.

Optimizing the selection and sequencing of endocrine and targeted therapies for hormone-sensitive, human epidermal growth factor receptor 2 (HER2)–negative advanced breast cancer is a rapidly evolving field owing in large part to an increasing pace of drug development coupled with a greater understanding of the genomic drivers of breast cancer. The recently published results from the MAINTAIN clinical trial begin to answer an important question in this patient population—can the well-established benefit with first-line cyclin-dependent kinase 4/6 (CDK 4/6) inhibitors be stretched further by continuing this drug class beyond progression and selecting an alternate endocrine therapy partner? We present a case of a patient with hormone-sensitive HER2 low metastatic breast cancer who underwent circulating tumor DNA next-generation sequencing to better inform her treatment options after progression on first-line therapy with a CDK 4/6 inhibitor and aromatase inhibitor. Our clinical approach in this patient population prioritizes the identification of actionable mutations with high-quality evidence for efficacy on the basis of clinical trials post-CDK 4/6 inhibitors, while balancing comorbidities and patient priorities for care. Several recent clinical trials discussed herein present clinically meaningful results linking emerging targeted therapies to actionable alterations in PIK3CA, ESR1, AKT1, and PTEN. Continued drug development in this space delays time to treatment with chemotherapy, and hopefully contributes to maintaining a high quality of life for these patients on primarily oral-based therapy.
Utility of multiparametric renal CT for differentiation of low-grade from high-grade cT1a clear cell renal cell carcinoma
Authors: Pickovsky Jana S , Alo Nasiyabi Khalid , Eldihimi Fatma , Schieda Nicola
Published: July 2023

Objective:

To determine if CT can differentiate low-grade from high-grade clear cell renal cell carcinoma (ccRCC) in cT1a solid ccRCC.

Methods and materials:

This retrospective cross-sectional study evaluated 78 < 4 cm solid (>25% enhancing) ccRCC in 78 patients with renal CT within 12 months of surgery between January 2016 and December 2019. Two radiologists (R1/R2), blinded to pathology, independently recorded mass:size, calcification, attenuation and heterogeneity (5-point Likert scale) and recorded a 5-point ccRCC CT Score. Multivariate logistic regression (LR) was performed.

Results:

There were 64.1% (50/78) low-grade (5/50 Grade 1 and 45/50 Grade 2) and 35.9% (28/78) high-grade (27/28 Grade 3 and 1/28 Grade 4) tumors.

Unenhanced CT attenuation was higher (35.9±10.3 R1 and 34.9±10.7 R2 high-grade vs 29.7±10.2 R1 and 29.5±9.8 R2 low-grade, p=0.01-0.02), absolute corticomedullary phase attenuation ratio (CMphase-ratio; 0.67±0.16 R1 and 0.66±0.16 R2 vs 0.93±0.83 R1 and 0.80±0.33 R2, p=0.04-0.05) and 3-tiered stratification of CMphase-ratio (p=0.02) lower in high-grade tumors.

A two-variable LR-model including unenhanced CT attenuation and CM.phase-ratio achieved area under the receiver operator characteristic curve of: 73% (95% confidence intervals 59–86%) and 72% (59–84%) for R1 and R2.

ccRCC CT score differed by ccRCC grade (p<0.01 R1, R2) with high-grade tumors occurring most commonly in moderately enhancing ccRCC score 4 (46.4% [13/28] R1 and 54% [15/28]).

Conclusion:

Among cT1a ccRCC, high-grade tumors have higher unenhanced CT attenuation and are less avidly enhancing.

Advances in knowledge:

High-grade ccRCC have higher attenuation (possibly due to less microscopic fat) and lower corticomedullary phase enhancement compared to low-grade tumors. This may result in categorization of high-grade tumors in lower ccRCC diagnostic algorithm categories.
Cellular and Molecular Homeostatic Microenvironmental imbalances in Osteoarthritis and Rheumatoid Arthritis
Authors: Munteanu Constantin , Onose Gelu , Turnea Marius-Alexandru , Rotariu Mariana
Published: July 2023

Abstract: Human movement is a complex and multifactorial process due to the interaction between the body and the environment. Movement is the result of activities of all the structures that make up a joint (i.e., ligaments, tendons, muscles, fascicles, blood vessels, nerves, etc.) and of the control actions of the nervous system on them. Therefore, many pathological conditions can affect the Neu-ro-Myo-Arthro-Kinetic System (NMAK). Osteoarthritis (OA) is the degenerative form of arthritis with a high incidence and a pro-longed course that affects articular and periarticular tissues such as articular cartilage, subchondral bone, and synovium, a degen-erative consequence. Instead, Rheumatoid arthritis (RA) is an immune-mediated synovial disease caused by a complex interaction between genetic and environmental factors. This review aims to compare Osteoar-thritis (OA) and Rheumatoid Arthritis (RA) in terms of pathogenesis and microenvironment and determine the main changes in a joint microenvironment regarding immunological defense elements and bioenergetics which can explain the pathological development with new thera-peutical opportunities.

Published: July 2023

Spinal muscular atrophy is a neuromuscular degenerative disorder characterized by progressive apoptosis of motor neurons, with severe weakness and bulbar dysfunction. The aim of the study was to analyze the correlations between the moment of initiation of treatment (nusinersen) and clinical evolution, and also the change of electrophysiological parameters and motor scales, fol-lowed up for 2 years. This study was carried out between 2018 and 2022 on 60 SMA children (29 girls, 31 boys), (29 type 1 and 31 type 2; 29 with 2 copies of SMN2, 29 with 3 copies, and 2 with 4 copies), aged between 3 weeks and 196 months, divided into 2 groups according type of SMA. For both types of SMA, statistically significant negative correlations were found between the elapsed interval from the onset of the disease to the initiation of treatment and upper motor acquisitions (type 1: p < 0.0001, r = -0.713, type 2: p<0.001, r = -0.560) and between age at the beginning of treatment and improvement in motor function (type 1: p <0.0001, r =-0.726, type 2: p<0.001, r=-0.553). For patients with type 2 SMA, a negative correlation was also identified between age at the time of onset and motor evolution (p<0.05, r = -0.378). Electrophysiological parameters were strongly positive correlated with motor improvement (p<0.0001, r=0.600). Our study established the necessity of early SMA diagnosis and therapy beginning, and demonstrated that Compound Motor Action Potential can be a predictive factor in the disease's progression.

Η σχολική ετοιμότητα των παιδιών προσχολικής ηλικίας έχει αναγνωριστεί ως ένας σημαντικός προβλεπτικός παράγοντας για τη μετέπειτα σχολική τους προσαρμογή στο δημοτικό σχολείο. Παρόλο που η βιβλιογραφία έχει υπογραμμίσει τη σημασία της σχολικής ετοιμότητας, υπάρχουν ελάχιστα εργαλεία για την αξιολόγησή της στην Ελλάδα. Σκοπός αυτής της μελέτης ήταν ο σχεδιασμός και ο έλεγχος των ψυχομετρικών χαρακτηριστικών μιας νέας Κλίμακας Αξιολόγησης Σχολικής Ετοιμότητας για Παιδιά Προσχολικής Ηλικίας (Κ.Α.Σ.Ε.Π.Π.Η.). Η κατασκευή της Κλίμακας βασίστηκε στη σχετική βιβλιογραφία, στο ελληνικό Αναλυτικό Πρόγραμμα (Α.Π.) Σπουδών και στις αντιλήψεις των εκπαιδευτικών (νηπιαγωγών και δασκάλων της Α΄ Δημοτικού). Πραγματοποιήθηκε μια πρώτη μελέτη, στην οποία συμμετείχαν 24 νηπιαγωγοί που συμπλήρωσαν την Κλίμακα για 102 παιδιά 5-6 ετών, για να διερευνηθεί η δομή και αξιοπιστία της. Στη συνέχεια, σε δεύτερη μελέτη, 80 νηπιαγωγοί (40 Γενικής Αγωγής και 40 Ειδικής Αγωγής) συμπλήρωσαν την Κλίμακα για 280 παιδιά 5-6 ετών (200 τυπικής ανάπτυξης και 80 παιδιά με Ειδικές Εκπαιδευτικές Ανάγκες), για να επιβεβαιωθεί η δομή της Κλίμακας και να διερευνηθεί η συγχρονική εγκυρότητά της. Την επόμενη χρονιά, 280 παιδιά επαναξιολογήθηκαν ως προς τις αντίστοιχες δεξιότητες στην Α΄ Δημοτικού για να διερευνηθεί η προβλεπτική εγκυρότητα της Κλίμακας. Από τις αναλύσεις προέκυψαν δύο βασικοί παράγοντες (μαθησιακές και κοινωνικο-συναισθηματικές δεξιότητες) με έξι επιμέρους παράγοντες (προφορικός λόγος, δεξιότητες γραμματισμού, μαθηματικές δεξιότητες, κινητικές δεξιότητες, δεξιότητες αυτορρύθμισης και αυτονομίας & κοινωνικής αλληλεπίδρασης). Επίσης, αναδείχθηκε ότι η Κλίμακα χαρακτηρίζεται από υψηλά επίπεδα αξιοπιστίας καθώς και συγχρονικής και προβλεπτικής εγκυρότητας. Τα αποτελέσματα συζητούνται ως προς την αξιοποίηση της Κ.Α.Σ.Ε.Π.Π.Η. από τις/τους νηπιαγωγούς και άλλους ειδικούς για την αξιολόγηση της σχολικής ετοιμότητας των παιδιών στο νηπιαγωγείο.
Personality, family relationships and school climate dimensions as predictors of dispositional forgiveness in adolescence
Authors: Lampropoulou Aikaterini , Lianos Panayiotis , Poulios Antonios
Published: July 2023

The mental health benefits of forgiveness are well-established in the literature. The growing research on dispositional forgiveness in adolescence is indicative of the need to better understand its role in youth’s well-being. In order to examine dispositional forgiveness in adolescence, measures regarding Big 5 personality factors (individual level), family relationships, school climate (system level), and sociodemographic variables at an individual and system level were used. Participants were 1,378 adolescents attending junior and senior high schools located in the broader area of Attica, Greece, randomly selected. Younger age, lower levels of neuroticism, and higher levels of extraversion, agreeableness and quality communication with the mother predicted higher forgiveness of self. Higher levels of openness to experience, agreeableness, quality communication with the father, positive behavior, positive attitude, and lower levels of lack of respect in the school predicted higher forgiveness of others. Finally, lower levels of neuroticism, higher levels of extraversion, agreeableness, and positive behavior in the school predicted higher levels of forgiveness of situations. The findings highlight the important role of personality factors and indicate the significance of primary prevention interventions in the school community regarding school climate that could contribute to the promotion of dispositional forgiveness and well-being of adolescents.

“You can be the kind of woman that you are”: the discursive management of intersecting identities in leadership talk
Authors: Corpuz Ember , Augoustinos Martha , Due Clemence
Published: July 2023

The present study investigates how culturally and linguistically diverse (CALD), and Aboriginal and Torres Strait Islander (ATSI) women mobilize intersecting identities through speeches delivered during women in leadership forums. As more women aspire to positions of leadership, the discursive analysis of identity management for understanding how identities are made relevant is critical. Using a discursive psychological approach, this research examines intersectionality as a social action, as it is played out in practice rather than as a theoretical concept. Here it is being anchored to empirical data to explore how it operates in the broader context of leadership talk, in particular, how diverse women represent themselves as leaders and what key identities emerge. The analysis demonstrates that in accounting for how these women achieved leadership positions, the speakers used their multiple identities as strategic resources. These identities included the categories of race, culture, gender, and parenthood. The insights from this study are significant as they shed light on the persisting barriers for women in achieving equal opportunity.
Exploring marginalized and privileged gender identities: the expectations of Muslim Roma adolescents on their future employment and family life
Authors: Sakka Despina , Papazoglou Irene
Published: July 2023

The aim of the present study is to explore the expectations of adolescents of a minority (i.e., of Roma and Muslim cultural backgrounds from the area of Thrace)[1] and majority status (i.e., dominant group) on their future employment and family life as well as on gender relations. Ninety-one adolescents participated in the study (51 from the dominant group and 40 from the minority, 45 boys and 46 girls). While all participants from the dominant group attended the 3rd grade of Gymnasium or the 1st grade of Lyceum only 8 Muslim Roma participants did so. Adolescents were asked to fill in a questionnaire and to write a short essay titled "A day in my future family". Data were collected in written from the participants of the dominant group and orally from those of Muslim Roma origin. In addition to the statistical analysis, and with respect to the data from the essay, a thematic analysis was carried out in order to identify the adolescents’ images of their future life in both the private and the public sphere. The results of the study reveal the multiple gender identities that are constructed by culturally diverse, with respect to gender and social status, groups of adolescents. They, also, suggest that the participants’ views are shaped by the marginalized or privileged categories in which they belong to. Finally, results show that as boys and girls of both the minority and the dominant groups project themselves in the future, they try to actively construct the social context they will live in, to position themselves within it and to provide meaning to gender relations.

 

[1]The Thracian minority is the only officially recognized minority in Greece and its position is guaranteed by the Treaty of Lausanne (Dragonas & Fragoudaki, 2006). The Thracian minority is not an ethno-culturally homogenous group. Τhese are Greek citizens who are either Roma or of Turkish or Pomak origin. Moreover, it is accorded religious but not ethnic status.

Published: July 2023

Vigorous germination and growth are linked to crop yield. This study was carried out to assess the effect of steeping duration and metabolite concentration on priming of 5 different crops, using the metabolites of five (5) bacterial isolates that were also characterized through Gas Chromatography-Mass Spectrometry (GC-MS). The crop seeds were steeped in cold-extracted metabolites of the 5 isolates for a known period (1, 2, 3, 4, and 5 h) and then also in different metabolites concentrations for a known duration determined as optimal in the first experiment. Characterization of cold-extracted metabolites was also carried out using GCMS. The results of this study revealed that steeping cowpea and soybean for longer durations (< 3 h) could be inhibitory to growth and development. For concentration it was either a case of lower concentration being optimal or there was no detectable pattern with concentration. The metabolites of the different isolates revealed the present of some common molecules, and some of the GCMS-identified metabolites (e.g., Hexadecanoic acid) have been shown to possess growth promotion properties in other studies. This study highlights that large endosperm seeds such as cowpea and soybean are more prone to the negative effects of steeping for longer durations, and further experiments should be carried out to isolate and purify the bioactive moieties for further studies and onward application.

Food delivery network: non-humans as consumption mediators
Authors: Guarnieri Fernanda , Vieira Francisco Giovanni David
Published: July 2023

The purpose of this theoretical essay is to present an understanding of how the practices of actors in a given network are impacted from the mediation of a digital device. As a contribution to studies of marketing, we present a conceptual framework covering the main actors that make up the food delivery service network. From the propositions, we argue that digital applications of supply and demand for food delivery, through its use, act as mediators between actors, causing the reformatting of market practices and, simultaneously, the institution of new consumption practices involving the entire network in which they operate.

Published: July 2023

Objetivou-se investigar as relações existentes entre produção, sustentabilidade e sucessão geracional de propriedades leiteiras em Minas Gerais. Utilizou-se a Modelagem de Equações Estruturais para testar nove hipóteses identificadas na literatura sobre o tema. Propriedades social e economicamente sustentáveis podem contribuir com o aumento da sucessão familiar. Além disso, propriedades que produzem mais leite podem ter maiores possibilidades de contribuírem para que jovens permaneçam na atividade leiteira. A sucessão geracional foi influenciada, de forma direta, pela sustentabilidade econômica e social e, de forma indireta, pela escala de produção.

Authors: Vieira Neuza , Ferreira Luciana , Vaz Samir , Silva Athos
Published: July 2023

Inspirada em Bloom et al. (2013), a presente pesquisa objetivou a mensuração do efeito do treinamento baseado em um PDL específico, o coaching, no desempenho de 100 gestores e 300 operadores em 10 das 23 lojas de um grupo lojista de faturamento na casa dos R$3 bilhões. Além disso, foram investigadas as percepções de 750 consumidores em dois momentos. A hipótese norteadora do trabalho foi que as lojas que receberam treinamento apresentariam desempenho superior quando comparadas às lojas que não receberam. Os resultados da pesquisa não confirmaram a hipótese apresentada, uma vez que, apesar de observação de melhora significativa em parâmetros avaliados, esse efeito foi registrado tanto nas lojas que participaram do treinamento quanto nas demais. Os parâmetros que se destacaram como beneficiados da intervenção foram os de “Planejamento e Organização” e “Gestão do Tempo”.
Interrogative Sentence as a Temoforming Component of Everyday Dialogue (Based on the Material of a Literary Text)
Authors: Loginov A.
Published: July 2023

The article is devoted to the consideration of the role of the interrogative sentence in the organization of the dialogical space of a literary text. The relevance of the study is due to the continuing interest in dialogue as the main form of speech, the insufficient degree of knowledge of the functional load of the interrogative sentence in it. The purpose of the article is to consider the interrogative sentence as a temoformulating component of the dialogue. The study uses the method of component analysis, the method of continuous sampling of illustrative material. The analysis of the linguistic material showed that the interrogative sentence has a priority role in the organization of the dialogue in comparison with other functional types of sentences. The interrogative sentence is a structure–forming component of the dialogical space that determines the topic of speech contact and, as a result, the content as a whole. The results of the study can be used in the formation of the speech culture of native speakers.
Communicative, psychological and information-psychological impact in mass communication
Authors: Zaripov Ruslan
Published: July 2023

The article is devoted to revealing the correlation between different types of communicative influence in interpersonal and mass communication. The relevance lies in the definition of the term "information-psychological impact", which eliminates the gap in the science of language, resulting from the expansion of the impact essence on the addressee beyond the purely verbal, and combines both linguistic and audiovisual means, the former implementing the verbal, and the latter – non-verbal impact.

Aim. To examine the relationship between communicative, psychological and information-psychological influences and define their conditional mutual boundaries in the context of interpersonal and mass communication.

Methodology and research methods. The study is based on an analysis of sources on communication theory, psychology, psycholinguistics, verbal impact linguistics, as well as information warfare and information-psychological influence. The methods of functional, communicative-pragmatic and synchronic-diachronic analysis are used. The work uses predominantly inductive-descriptive and comparative methods of presentation.

Results. The generic concept among the analyzed types of influence is communicative, which is associated with any type of information exchange, including those beyond the limits of verbal and audiovisual tools. Within the framework of verbal and non-verbal communication, the impact of the information subject can acquire a psychological character, if the mental state, social attitudes or psychological characteristics of the recipient relating to his activity, consciousness or personality are affected. Within the framework of mass communication, we should talk about the impact on the recipient's psyche by means of mass information – information-psychological impact.

Scientific novelty. Within the framework of communication theory, information-psychological warfare linguistics and applied linguistics in general, a definition of information-psychological influence is introduced, its essence is established and its main characteristics are noted.

Practical significance. The introduction of this term eliminates the terminological polyvalence that exists in communicative science regarding various types of impact, and from an applied point of view will make it possible to identify patterns of use of linguistic and extralinguistic means in media texts, as well as to analyse media materials related to the category of information and psychological weapons.
Analysis of the relationship between serum sodium concentration and laboratory parameters in diabetic patients
Authors: Aab Arkadiusz , Zarańska Julia , Kędra Kamila , Michalik Izabela , Bielak Maciej , Zarański Bartosz
Published: July 2023

Introduction: Diabetes is a chronic civilization disease that is associated with numerous complications and disturbances in laboratory parameters. One of the observed changes in laboratory studies of individuals suffering from diabetes is a significantly low level of sodium.

Aim of study: The aim of study was to compare natremia with selected blood parameters determined on admission to hospital, and then to find correlation, if any, between those parameters.

Materials and methods: We retrospectively reviewed the medical records of 169 patients with diagnosed type 2 diabetes and the average age of 72.43±11.62 years. We tested the correlation between natremia and: total, LDL and HDL cholesterol; creatinine; potassium; calcium; eGFRCKD-EPI and alanine aminotransferase levels in the patients. Statistical analysis was run on STATISTICA 13. The nonparametric Mann-Whitney, Spearmans’ rank correlation and the Shapiro-Wilk tests were used to analyse factors affecting laboratory test results for the patients, perform correlation analyses and check the conformity with normal distribution, respectively.

Research results: A positive correlation was revealed between LDL level and natremia (p = 0.023), as well as between natremia and chloride ion concentration (p < 0.001) in the patients’ blood. No correlation was found between natremia and sex, age, eGFRCKD-EPI, alanine aminotransferase, HDL cholesterol, triglycerides, creatinine, as well as calcium and potassium concentrations.

Conclusions: Statistically significant correlations were found exclusively between LDL level and natremia, and between chloride and sodium concentrations. High LDL level was correlated with high natremia, which requires further research due to the scant literature. The sodium, potassium and chloride concentrations are known to be interconnected by the need to ensure the electrolyte balance, as seen in the Gamble diagram. The remaining parameters were not statistically significant.

Wątki medyczne w biografiach wybitnych Wielkopolan: Stanisława Staszica i Augusta Cieszkowskiego
Authors: Początek Michał
Published: July 2023

Sięgając do wspomnień, osobistych listów oraz dostępnych dokumentów, poddano analizie wątki zdrowotne w biografiach dwóch wybitnych Wielkopolan, Stanisława Staszica (1755-1826) i Augusta Cieszkowskiego (1814-1894). Obaj zasłużyli się Rzeczypospolitej owocną działalnością na płaszczyźnie naukowej i społecznej. Ich aktywność przypadła na trudny, burzliwy okres w dziejach Polski, czas upadku państwowości, utraty niepodległości, dramatycznych zrywów powstańczych i wreszcie zaborów oraz ponad wiekowego ucisku. Znakomici mężowie opowiadali się raczej nie za militarną konfrontacją z wrogami, a za pokojową, acz stanowczą rywalizacją na polu gospodarczym i naukowym. Stawiali na pracę u podstaw, na znaną i sprawdzoną w tradycji Wielkopolski pracę organiczną. Czerpali z twórczego dorobku Oświecenia, ale wzbogacali je o własne prorocze wizje. Niezwykle uzdolnieni i wszechstronni, podejmowali również inicjatywy na rzecz zdrowia publicznego. Obie postacie przedstawiono od mniej znanej, bardziej prywatnej strony. Posągowym biografiom nadaje ona ludzkie, bezpośrednie oblicze i je po prostu ożywia. Przybliża tym samym sprawy, którym się poświęcili, przypomina ich dzieło.
