Published: May 2024

AIM: This study aimed to assess the reproductive health of adolescent girls with obesity living in a large industrial territory.
MATERIALS AND METHODS: A one-time study was conducted on 105 teenage girls aged 15–17 years. The main group consisted of 70 girls with overweight and obesity, who were divided into a group with menstrual irregularities (N1=42) and without disorders (N2=28). The control group included 35 girls with normal body weight and no menstrual irregularities. Morbidity was studied. Body mass index (BMI), pituitary (thyroid-stimulating hormone [TSH], follicle-stimulating hormone, and luteinizing hormone) and sex hormones (estradiol, DHEA-SO4, AMH, and testosterone), alanine aminotransferase, aspartate aminotransferase, total cholesterol, and ultrasound data of the thyroid gland and abdominal organs were determined. A quantitative assessment of treatment adherence and lifestyle modification was performed.
RESULTS: The average BMI values in the main and control groups were 31.1 (4.9) and 20.0 (1.9) kg/m2, respectively (p 0.001). A statistically significant predominance of the incidence of cardiovascular pathologies was found in the main group (χ2=2.58, p=0.014; OR=5.7; 95% CI, 1.2–26.2), as well as a more frequent occurrence of urinary tract, nervous system, and endocrine diseases. In the main group, echographic signs of liver and pancreatic pathologies were detected in 22 (31.4%) girls and diffuse changes in the thyroid gland in combination with cystic formations or hypoplasia in 31 (44.0%). The number of antral follicles was normal in all patients. A statistically significant difference in TSH (p 0.001), LH (p=0.015), and DHEA-SO4 (p=0.002) was obtained between the main and control groups. Adolescents aged 15 years were more adherent to treatment (χ2=13.28; p=0.003).
CONCLUSION: Statistically significant differences in clinical and laboratory data and treatment adherence were found in adolescent girls with overweight and obesity living in a large industrial region when compared with healthy girls, which dictates the need to improve and implement personalized medical and psychological programs.
Immunohistochemical study of the nervous structures of the mediastinal organs
Authors: Chumasov Evgenii I. , Petrova Elena S.
Published: May 2024

BACKGROUND: No studies have sufficiently evaluated the innervation of the mediastinal organs in the P1 period when the blood circulation switches from placental to pulmonary and the regulation of respiration and functioning of the cardiovascular system begin.
AIM: This study aimed to conduct a comparative immunohistochemical analysis of the innervation of the mediastinal organs of newborn rats.
MATERIALS AND METHODS: Immunohistochemical methods were employed for identifying neuronal markers: PGP 9.5 protein, tyrosine hydroxylase, and synaptophysin. Primary antibodies were applied to mediastinal sections after they had been deparaffinized.
RESULTS: Analysis of frontal sections of the cardiopulmonary complex of rats at P1 showed that the bronchi, esophagus, great vessels (aorta and pulmonary artery trunks), veins (pulmonary and caval), adipose tissue, lymph nodes, lung fragments, and heart occupied the upper and middle sections of the mediastinum. Closely adjacent parasympathetic and sympathetic ganglia, microganglia, nerve trunks, and plexuses of nerve fibers were identified using neuronal markers in the interstitium between organs. In the upper and middle mediastinum of newborn rats, synaptic structures were identified in the ganglia and paraganglia, mixed lobules of adipose tissue, esophageal and bronchial wall, around small arteries and arterioles for the first time using immunohistochemical methods.
CONCLUSION: This comparative study revealed that in the early period of postnatal development of rats, the walls of the esophagus, trachea, and main bronchi are most innervated in the mediastinum; in the myocardium and lungs, these nervous apparatuses are typically rare or absent. A high concentration of synaptic structures in the conducting myocardium has been described.
Influence of sex and degree of prematurity on the heart structure in the late postnatal period of ontogenesis
Authors: Ivanova Vera V. , Serebryakova Оlga N. , Erokhina Alexandra V. , Nikonova Anastasia D. , Milto Ivan V.
Published: May 2024

BACKGROUND: People born prematurely have an increased risk of early heart disease. However, to date, based on the results of clinical studies, drawing a clear conclusion about the influence of sex and degree of prematurity on the structure of the heart of people born prematurely is impossible. Experimental studies aimed at identifying the structural features of the myocardium of preterm animals depending on the sex and degree of prematurity are relevant.
AIM: To present the morphological characteristics of the left ventricle of preterm rats on days 42–180 of the postnatal period of ontogenesis, taking into account sex and degree of prematurity.
MATERIALS AND METHODS: The study was conducted on full-term, 12- and 24-h preterm male and female Wistar rats. Each group included 24 animals, including 12 males and 12 females. To obtain premature rat offspring, preterm birth was induced by antiprogestin mifepristone (10 mg/kg) injection. Histological and immunohistochemical studies of the left ventricle of premature male and female rats were performed on days 42, 56, and 180 of the postnatal period of ontogenesis. The following parameters were determined in the left ventricular wall: wall thickness, diameter and relative volume of the cardiomyocytes, and number of caspase 3-positive cardiomyocytes in 1 mm2 of the myocardium.
RESULTS: The left ventricular wall of preterm and full-term animals on days 42–180 of the postnatal period of ontogenesis has a fundamentally similar structure. However, preterm birth, regardless of sex, leads to a decrease in the relative volume of left ventricular cardiomyocytes. On day 56 of the postnatal period of ontogenesis, the number of caspase 3-positive cardiomyocytes increased only in male rats with a greater degree of prematurity.
CONCLUSION: Preterm birth influenced the relative volume of the cardiomyocytes and number of caspase 3-positive cardiomyocytes of the left ventricle; however, the influence of sex and degree of prematurity on these parameters is unclear. An earlier increase in the number of caspase 3-positive cardiomyocytes in the left ventricle of rats born 24 h preterm indicates the different adaptive potential of the myocardium of animals with different degrees of prematurity. The results of the study suggest a cardioprotective effect of female sex steroids in premature animals.

Published: May 2024

We develop candidate hybrid models representing the spatial distribution of earthquake occurrence in New Zealand over the next 100 yr. These models are used within the onshore/near-shore, shallow component of the distributed seismicity model within the New Zealand National Seismic Hazard Model 2022. They combine a variety of spatially gridded covariates based on smoothed seismicity, strain rates, and proximity to mapped faults and plate boundaries in both multiplicative and additive hybrids. They were optimized against a standardized catalog of New Zealand earthquakes with magnitude M ≥ 4.95 and hypocentral depth ≤40 km from 1951 to 2020. We extract smoothed seismicity covariates using three different methods. The additive models are linear combinations of earthquake likelihood models derived from individual covariates. We choose three preferred hybrid models based on the information gain statistics, consideration of the ongoing Canterbury sequence and regions of low seismicity, and inclusion of the most informative covariates. Since the hazard model is designed for the next 100 yr, the preferred hybrid models are also combined with 20-year earthquake forecasts from the “Every Earthquake a Precursor According to Scale” model. Thus, in total, six hybrid spatial distribution candidates are advanced for sensitivity analyses and expert elicitation for inclusion in the final logic tree for the New Zealand National Seismic Hazard Model.
Quake-DFN: A Software for Simulating Sequences of Induced Earthquakes in a Discrete Fault Network
Authors: Im Kyungjae , Avouac Jean-Philippe
Published: May 2024

We present an earthquake simulator, Quake-DFN, which allows simulating sequences of earthquakes in a 3D discrete fault network governed by rate and state friction. The simulator is quasi-dynamic, with inertial effects being approximated by radiation damping and a lumped mass. The lumped mass term allows for accounting for inertial overshoot and, in addition, makes the computation more effective. Quake-DFN is compared against three publicly available simulation results: (1) the rupture of a planar fault with uniform prestress (SEAS BP5-QD), (2) the propagation of a rupture across a stepover separating two parallel planar faults (RSQSim and FaultMod), and (3) a branch fault system with a secondary fault splaying from a main fault (FaultMod). Examples of injection-induced earthquake simulations are shown for three different fault geometries: (1) a planar fault with a wide range of initial stresses, (2) a branching fault system with varying fault angles and principal stress orientations, and (3) a fault network similar to the one that was activated during the 2011 Prague, Oklahoma, earthquake sequence. The simulations produce realistic earthquake sequences. The time and magnitude of the induced earthquakes observed in these simulations depend on the difference between the initial friction and the residual friction μi−μf, the value of which quantifies the potential for runaway ruptures (ruptures that can extend beyond the zone of stress perturbation due to the injection). The discrete fault simulations show that our simulator correctly accounts for the effect of fault geometry and regional stress tensor orientation and shape. These examples show that Quake-DFN can be used to simulate earthquake sequences and, most importantly, magnitudes, possibly induced or triggered by a fluid injection near a known fault system.

Published: May 2024

The escalating use of English as a primary mode of communication in Bandung City is impacting the younger generation's interest in learning and using the Sundanese language. This quantitative study investigates the correlation between English and Sundanese language usage among 100 respondents aged 12-21, employing correlation and simple linear regression tests. Results indicate a negative influence of English on Sundanese usage, with higher English usage correlating with lower Sundanese use (correlation coefficient: -0.622, English's effect on Sundanese: 59.5%). The decline in Sundanese usage is attributed to environmental factors, education, and peer interactions. Recommendations include promoting Sundanese among Generation Z to preserve the language.

Published: May 2024

Background: Celiac disease (CD) is an autoimmune gastrointestinal disease caused by intolerance to gluten. Celiac disease is an important cause of failure to thrive in children. In addition to intestinal and extra intestinal clinical features, the diagnosis of CD is based up on histological findings in duodenal or jejunal biopsies, which may present in various forms.
Methods: The study was a prospective observational, cohort study, including all children between 2-18 yrs. of age presented with failure to thrive fulfilling criterias of study. The patients with increased levels of IgA anti tTGA were selected for upper gastrointestinal endoscopy and duodenal biopsy. The aim of study is to study the prevalence and clinical profile of CD in children with failure to thrive.
Results: A total of 66 cases of failure to thrive/short stature were enrolled, with prevalence of 24.2% of CD.  Male: Female ratio was 1:1 in children with CD. Clinical features include weight loss (62.5%), irritability (37.5%), anemia (37.5%), diarrhea (37.5%). On biopsy cases 87.5% cases of failure to thrive had Marsh grading of grade 3 and 12.5% had Marsh grade 2.
Conclusions: Failure to thrive patients with diarrhea and anemia should be evaluated upfront for celiac disease.

Published: May 2024

Background: Anaemia in pregnancy is a serious health issue faced globally by all countries. Noncompliance to iron and folic acid supplement plays a role in the high prevalence of anemia in pregnant women.
Objectives: The objectives were to find out the proportion of compliance to iron and folic acid tablets (IFA) among antenatal mothers and to determine factors associated with it.
Methods: A cross sectional study was conducted among 260 antenatal mothers attending antenatal clinic in a tertiary care hospital in Jharkhand from August 2023 to February 2024. Subjects were recruited through consecutive sampling. A pretested, predesigned, semi structured interview schedule was used to collect information. Data were analyzed using SPSS 15.0. Chi square was used to find out the association of compliance with independent variables. P value of <0.05 was considered as significant.
Results: Among the study participants, majority (55.7%) were above 26 years’ age and 60% stayed in rural area. Overall, 64.2% stayed in joint family. The proportion of compliance to IFA among antenatal mothers was 58.8% (n=153), and the reason for noncompliance (n=107) in the majority was forgetfulness (46.7%) followed by “side effects” (28%). Factors like socio economic status and type of family have shown significant association with this compliance.
Conclusions: This study highlighted that only around half of the pregnant women are compliant with IFA, and this situation demands for information education and communication activities to generate awareness.

Published: May 2024

Terahertz (THz) waves, occupying a unique position bridging microwave and infrared wavelengths, exhibit promising potential across diverse domains, particularly in medicine. With attributes such as non-ionizing nature and notable resolution capabilities, THz waves offer avenues for non-invasive medical applications. In cancer diagnosis, THz spectroscopy emerges as a pivotal tool for qualitative and quantitative analysis of biomarkers, enabling swift and accurate differentiation of substances based on molecular structure. Despite challenges such as limited penetration depth in tissue, THz imaging proves invaluable in discriminating cancerous tissues from normal ones during surgery. In this paper we have summarized recent research results on practical implementation of THz waves in medicine. Recent advancements in in vivo imaging showcase promising results, although challenges persist in human-based studies due to tissue complexity. Integration of advanced algorithms enhances the accuracy of cancerous tissue identification. Additionally, THz spectroscopy finds versatile applications in pharmaceuticals and life sciences, offering insights into molecular interactions critical for drug efficacy and understanding protein conformations. Further advancements in THz systems, including enhanced light sources and detectors, are crucial to propel biomedical research forward. Establishment of a comprehensive THz spectrum database will augment existing data, emphasizing the potential of THz waves to revolutionize medical diagnostics and treatment modalities.

Authors: George Sylvia , Jha Anupriya , Giri Anjan Kumar
Published: May 2024

A resource-limited country like India calls for a deeper focus on preventive health than it is now. So far, behaviour change communication (BCC) has been more or less limited to campaigns and awareness activities. Treating physicians applying BCC interventions in their clinics is particularly rare. This article aims to describe the role of BCC at the primary healthcare level in preventing diseases. The article also attempts to highlight the importance of BCC in helping cure and rehabilitate patients. Evidence-based interventions can be derived from BCC models that help physicians handle their patients better. Health education an already defined domain of health promotion will be the key to achieving the said goal. It promises to be one of the cheap and effective tools in achieving the vision of universal healthcare. It provides room for flexibility and customised care for each patient. After a thorough understanding of various models and theories of BCC, a physician should be able to apply them on a regular basis in their day-to-day interaction with patients in the most scientific manner possible.

Authors: Avhad Tanmay A. , Shrivastava Vanksha , Gunay Siddharth , Misal Ankush , Bhangde Saurabh
Published: May 2024

Tuberculosis presents a significant health challenge, with extrapulmonary cases comprising 15-20%. Spinal tuberculosis often leads to neurological deficits, requiring surgical intervention such as Hartshill system fixation. Various posterior instrumentation methods are employed, with sublaminar wiring pioneered by Luque and enhanced by Dove's Hartshill system for superior biomechanical performance. This case underscores Hartshill system's efficacy in stabilizing the spine post-tubercular destruction, offering a cost-effective alternative to pedicle screws. An 18-year-old presented with 6-month upper back pain, progressing weakness in lower limbs, weight loss, and fever. Radiographs revealed D7-D9 vertebral destruction, leading to kyphosis. MRI showed paradiscal bony destruction and abscess, suggestive of tubercular spondylodiscitis. Surgery with Hartshill rectangle and sublaminar wiring provided kyphosis correction. Post-operative Gene-Xpert confirmed tuberculosis. Mobilization and chemotherapy led to limb power restoration within 3 months, with ongoing rehabilitation and consolidation of affected segments with complete recovery by eight months. Instrumented stabilization in spinal TB prevents kyphosis and graft complications; Hartshill loop rectangle and sublaminar wire fixation, cost-effective and suitable for resource-poor settings, offer comparable outcomes to pedicle screws, enabling hybrid fixation, especially in low-income countries.

Published: May 2024

It is illustrated the Chebyshev polynomials are the exact-endomorphisms that are conjugated to the piecewise linear chaotic transformations. Explicit nonstationary solutions of the Perron — Frobenius equations for the chaotic Chebyshev maps are found. Their convergence to invariant densities is analyzed. The results allow one to treat the Lyapunov exponent as the rate of such convergence. Some chaotic maps that are monotonically related to the tent map by Jacobian elliptic functions and Gaussian lemniscate ones and characterized by invariant distributions in the form of elliptic integrals are constructed.

Published: May 2024

We study here different modes of self-oscillations in ring Toda chain with negative friction. Assuming that at small friction the shape of self-oscillations is close to one of the known Toda soliton-like solutions we use analytical methods in combination with numerical ones for study о the self-oscillations. We show that а Toda chain consisting of N elements possesses N+1 different modes of self-oscillations. Among them two modes correspond to left and right rotations of the chain as a whole with a constant velocity. Each of the other modes represents а combination of moving soliton and the rotation with a velocity depending on the mode number. Only for the mode corresponding to anti-phase oscillation of the chain neighboring elements (such oscillation are possible for an even N) the constant component of velocity is equal to zero.

Published: May 2024

The task of experimental investigation of some synchronous chaotic communication systems in order to compare their qualitative and energy features is formulated and solved in this paper. The first of investigated systems was а receiver—transmitter device with additive mixing of an informative component to a chaotic carrying signal, second — а device with nonlinear injecting о informative component into the source of chaotic oscillations, third — a structure of communication combining the additive mixing at the transmitting side and synchronous chaotic response at the receiving side. For objective comparison of obtained results the systems being analyzed were realized on a basis of the same radiophysic model of autogenerator with three-dimensional phase space. The physical experiments have shown that under the condition of confidential transmitting of analogous signals for the first two kinds of the systems а quality of signal restored in their receivers is nearly same. However the use of a nontrivial approach in combining the additive mixing informative component at the transmitting side and the synchronous chaotic response at the receiving side allows to improve essentially a quality of informative component being restored and to increase an enegy potential of the communication channel.

This allows for students to receive individualized Monterrey is number 4 in The Princeton Review’s Top Undergraduate Schools for Entrepreneurship Ranking 2023. The school uses process-based approaches to EE. Guided by the Theory of Planned Behavior (TPB), we assessed changes in the students’ attitudes toward entrepreneurship, perceived behavioral control, and intentions to become an entrepreneur. Using a seven-point Likert scale, the data was collected using anonymous online links at two points during the semester: the beginning of the semester (T1) and the end of the 1st Period (T2). The data was analyzed with SPSS software and the Friedman Calculator. Our research findings indicate a high score at T1. There was a slight change at T2, but the change was not statistically significant. Consequently, we introduce and review other approaches to Entrepreneurship Education that might be more effective. Noteworthy is that the sample is immersed in an entrepreneurial university context, both within and outside the academic setting, which fosters a strong motivation among students to contribute societal value through entrepreneurial endeavors.

The case of task-oriented, polite discourse in intercultural aviation and customer service interactions
Authors: Friginal Eric
Published: May 2024

Applied corpus linguistics (ACL) as a methodological approach in language and social research has contributed important linguistics-based explications of discourse with critical language policy implications. ACL is understood to include the use of corpus resources, techniques, and tools in order to, for example, examine patterning in public discourses so as to obtain novel understandings of how language is used and construed in specific contexts (Thompson & Friginal, 2020).  This paper presents results of two interrelated (case) studies exploring corpus distributions, in particular, of politeness markers, in  aviation English communication and outsourced call center interactions. Both specialized corpora, Cross-Cultural Aeronautical Communication Corpus (CCACC) and Corpus of Outsourced Customer Service Calls (Co-CSC) are annotated across socio-cultural structures and task dimensions of interaction in these settings, focusing especially upon speakers’ role-relationships, discoursal goals and objectives, cultural identities, and power dynamics (Baker, 2021; Egbert, Biber, & Gray, 2022; Vine, 2020). Distributions of grammatical politeness markers (e.g., thanks, let's, and speech acts, polite requests, apologies, etc.) are interpreted by focusing on their macro and micro policy implications, especially highlighting emerging mismatches between linguistic realities (i.e., from corpora) and industry expectations.
A corpus-assisted semantic profile of the noun representation in CAD and CADS studies on newspaper discourse
Authors: Del Fante Dario
Published: May 2024

The abstract must not exceed 300 words (among other reasons, because the text box will not accommodate it) The existing literature on newspaper discourse from a CAD (Critical Discourse Analysis) or CADS (Corpus-assisted Discourse Studies) perspective is extensive and there is a large volume of published studies that mention the noun representation in their titles or who put the representation in the press as the main object of investigation. Generally, these works focus on the use of language to represent a social phenomenon like migration, Islam, Europe, homelessness, obesity, and many other events. However, except for some works, the explanation of what the act of representation means is often not directly and overtly addressed. However, the fact that the notion of representation is not often clearly defined in many works (generally for a matter of space) does not mean that the notion is taken for granted or the implications are not considered. For this reason, this paper investigates how the notion of representation is presented. On the basis that the meaning of an expression derives from its use in context, which is intended as all its manifestations through which the expression itself acquires its meaning, the aim of this work is to give a corpus-assisted discourse perspective on the use of the lexical item representation in the academic discourse focused on the news media.

It is imperative to comprehend the determinants shaping entrepreneurial intent, especially during pivotal junctures when individuals are navigating career decisions. This research endeavors to scrutinize the entrepreneurial intent of university students, with a specific focus on the sports domain, and examine the potential impact of their involvement in sports activities on said entrepreneurial intent. The participants comprised 415 students from the academic sports domain in four cities in Romania (Pitesti, Alba-Iulia, Cluj-Napoca, and Sibiu). They were administered a 35-item questionnaire and subsequently categorized into four groups based on their sports background: individuals and team sports participants with a competitive history, amateur athletes, and non-practitioners. The questionnaire demonstrated strong internal consistency (Cronbach's alpha coefficient = 0.755). Test of Homogeneity across criteria such as competitive sports involvement, type of competitive sports, and engagement in amateur sports revealed significant differences in five out of 45 comparisons. Furthermore, this study employs an explanatory approach to elucidate the distinctions among athletes, amateur, and non-athlete students in academic sports programs regarding: comfort and security in workplace stability, embracing risk-taking for gains, proactive problem-solving, expectations from superiors, work ethic and goal orientation, workload and productivity relationship, task completion and challenge acceptance, work avoidance and problem management, work-life balance prioritization, openness to personal development, parallels between sports and business strategies, taking initiative and responsibility, entrepreneurial determination, comfort zone preference and adaptation after sports career.

Aim: Circular training is thought to have a motivating feature by distracting the individual from routine and boring training practices with different exercise methods. In this context, the aim of this study was to investigate the effect of different rest periods applied during circular training on blood lactate levels. Method: The pretest-posttest model was used in the study. The sample of the study consisted of 24 (Xage =20,00±1,79; Xheight =171,75 ± 6,22; Xweight =75,01± 6,39) volunteer male basketball athletes. Lactate measurements were taken before, during and after circular training with different rest periods. The data was analyzed in the SPSS 24.0 package program, with a 95% confidence interval and a 0.05 significance level, and normality analysis was performed with the Shapiro-Wilk test. Since the data were not normally distributed, nonparametric tests were applied. The change in heart rate averages and lactate levels of the research group according to resting times were evaluated by Wilcoxon Test. Results: In general, it was determined that the circular training program with different rest intervals caused significant differences in the measurement parameters (Heart Rate, and Lactate) of the participants (p<0.05). It was observed that the average heart rate and lactate values reached during training decreased as the rest period of the research group increased. On the other hand, the effects of long-term circular training programs with different rest intervals on aerobic-anaerobic energy metabolism will contribute to the literature.
