M2 microglia transplantation has previously demonstrated beneficial effects on spinal cord injury (SCI) by regulating neuroinflammation and enhancing neuronal survival. Exosomes (EXOs), secreted by almost all cell types, embody partial functions and properties of their parent cells. However, the effect of M2 microglia-derived EXOs (M2-EXOs) on SCI recovery and the underlying molecular mechanisms remain unclear. In this study, we isolated M2-EXOs and intravenously introduced them into mice with SCI. Considering the reciprocal communication between microglia and astroglia in both healthy and injured central nervous systems (CNSs), we subsequently focused on the influence of M2-EXOs on astrocyte phenotype regulation. Our findings indicated that M2-EXOs promoted neuron survival and axon preservation, reduced the lesion area, inhibited A1 astrocyte activation, and improved motor function recovery in SCI mice. Moreover, they inhibited the nuclear translocation of p65 and the activation of the NF-κB signalling pathway in A1 astrocytes. Therefore, our research suggests that M2-EXOs mitigate the activation of neurotoxic A1 astrocytes by inhibiting the NF-κB signalling pathway, thereby improving spinal tissue preservation and motor function recovery following SCI. This positions M2-EXOs as a promising therapeutic strategy for SCI.

Authors: Obaje Sunday Godwin , Samuel Osita
Published: July 2023

Background: Due to various factors, blood lipid profiles may vary across ethnicities. These effects may be particularly prominent in athletes and dependent on nutritional status during training. This study aimed to investigate blood lipid variables in relation to age, sex, and nutritional status among athletes in Nigeria.Methods: A total of 202 athletes (112 males and 90 females) were recruited between February 2022 and April 2023 at the Ebonyi State Sporting Complex in Abakaliki. Body compositions were assessed using a bioelectrical analysis (BIA) model. A significance level of p<0.05 was used.Results: Significant differences were found in blood lipid. Male athletes had higher levels of total cholesterol (3.91±0.39) and LDL cholesterol (1.96±0.25) compared to female athletes (3.93±0.43 and 193±0.47). Furthermore, older athletes had higher levels of total cholesterol (3.91±0.39, p<0.05) and triglycerides (1.02±0.34, p<0.05) compared to younger athletes (3.86±0.36 and 1.07±0.38). Based on BMI categories, approximately 37.6% of the individuals in the sample were classified as normal, 34.2% as overweight, and 28.2% as obese.Conclusion: This study provides valuable insights into the differences in blood lipid variables among athletic populations, shedding light on the cardiovascular health of athletes. These insights can inform targeted interventions and monitoring strategies.
SOLVATOCROMISMO E AS ESCALAS EMPÍRICAS DE POLARIDADE DO SOLVENTE: UMA REVISÃO
Authors: Paczkowski Ingrid , Campo Leandra
Published: July 2023

SOLVATOCHROMISM AND THE EMPIRICAL SCALES OF SOLVENT POLARITY: A REVIEW. The term solvatochromism is used to describe the changes in the optical properties of a dye molecule by influence of the solvent characteristics. Solvatochromic shifts are governed by intermolecular interactions between solute-solvent that can be either electrostatic (non-specific interactions) or chemical (specific interactions). Due to the complexity of these interactions and absence of theoretical models that can explain the specific effects of solvent, different authors have introduced empirical parameters to building more reliable solvent polarity scales. Out of various polarity scales that have arisen from this need, those based on the effect of solvent polarity on the electronic excitation energy of indicator organic dyes are the most prevalent in literature. The use of empirical equations that correlate bathochromic (positive solvatochromism) and hypsochromic (negative solvatochromism) shifts of optical spectra of organic molecules with the polarity of solvent has become essential for understanding solute-solvent interactions. This review article presents main mathematical equations that use linear correlations between macroscopic and/or microscopic polarity functions of solvent with spectroscopic parameters of solute (dye) in construction of solvent polarity scales. In addition, main mathematical models that use solvatochromic shifts to estimate the dipole moment of ground and excited state are discussed.

The task of monitoring the condition of the tissue during its cryodestruction is extremely relevant for cryosurgery. Previously, the concept of a sapphire cryoprobe was proposed, which makes it possible to detect diffusely scattered light from a tissue during an ice ball formation. This probe combines the advantages of sapphire as a promising material for cryosurgery, as well as the possibility of assessing the depth of tissue freezing in the contact area. The use of several light source channels inside the applicator, spaced at different distances from the detector channel, makes it possible to analyze the scattering properties of the medium using the methods of diffusion theory. In this paper, we consider the influence of the position and number of analyzed source channels on the signals recorded by the detector channel and the determined effective scattering coefficient of a two-component medium consisting of an iceball and unfrozen tissue. Differences in the scattering coefficient obtained for various channel configurations are shown, as well as the advantages of analyzing a large number of channels to describe the effective properties of the medium with a complex iceball boundary.

Comparative analysis of infrared (IR) spectra of blood serum of healthy donors and patients with multiple myeloma (MM) was performed. MM is characterized by hyperproduction of the paraprotein, which manifests itself in a change in the spectral pattern of mid-IR absorption spectra. It has been shown that the most significant deviations in the spectra were observed for samples of MM near the Amide I and Amide II´ bands. As a result of a comparative analysis of the IR spectra of blood serum in the region of 1700-1350 cm-1, nine parameters were established, the average values of which in the samples obtained from patients with a secretory form of MM differ significantly from similar indicators for the serum of healthy donors.

Chlorosomal bacteriochlorophylls are the main photosynthetic pigments of green sulfur bacteria – anoxygenic phototrophic microorganisms. The spectral properties of chlorophylls of higher plants, algae and cyanobacteria are well studied, however, the spectral-luminescent properties of their related compounds, bacteriochlorophylls, which participate in anoxigenic photosynthesis, are practically not described in the scientific literature. The polarity of the solvent and the environment have a significant effect on the emission spectra (bacterio)chlorophylls, which is expressed in the spectral shift of the absorption and fluorescence maxima, as well as changes in the fluorescence intensity. The spectral characteristics of bacteriochlorophylls d and e were obtained in organic solvents such as acetone, methanol, ethanol and isopropanol, as well as in acetone-ethanol (7:2) and acetone-methanol (7:2) mixtures. These solvents are most often used for the extraction of bacteriochlorophylls from bacterial cells, so the work will be useful for the development of methods for the quantitative determination of chlorosomal bacteriochlorophylls in bacterial cells or in samples of natural water.

The effect of different models of artificial light exposure on the aggregation activity of platelets of white male rats using a continuous Light-Light (LL) lighting model and models with alternating Light-Dark (12:10) and Light-Dark (18:6) light and dark modes was studied. Analysis of platelet aggregation activity was performed with a computerized 230LA "Biola" aggregation analyzer using the method of V.A. Gabbasov. It was found that under light exposure in the body of laboratory animals there is an increase of platelet aggregation activity accompanied by an increase in the parameters of the weighted average radius curve and the parameters of the light transmittance curve. Alteration of circadian rhythms in the form of impaired photoperiodism leads to an increase in platelet aggregation activity and provokes the development of microcirculatory disorders. The most pronounced changes in the microcirculatory bed by day 10 of the experiment are formed using the Light-Dark model (18:6).
Prosecutors' Considerations when Initiating Plea Bargaining
Authors: Tisdale Casey , Votruba Ashley
Published: July 2023

Prosecutors are the key decision-makers when it comes to plea bargaining
(Ball, 2006; Davis, 2001), which is responsible for the resolution of
about 90% of criminal cases (Johnson, 2023). We distributed a
mixed-method survey to a national sample of 180 prosecutors to ask them
their key considerations when they initiate and prosecute a criminal
case. Additionally, our survey asked prosecutors to provide any
additional information they wanted to share regarding plea bargaining.
We then conducted a qualitative content analysis, informed by Schreier
(2012), to comprehensively identify the factors the prosecutors
discussed. We found several factors that prosecutors take into
consideration when starting to evaluate a criminal case: qualities of
the criminal defendant (e.g., criminal history), victim input (e.g.,
victim wishes), and factors specific to the case (e.g., evidence
strength). Additionally, when asked if they would like to share anything
regarding plea bargaining, some prosecutors stressed the necessity of
the plea system, some shared their punishment orientations, and others
discussed how they determine punishment on a case-by-case basis.
Overall, prosecutors tended to stress criminal history as largely
influential in their plea decision-making. This study provides insight
into prosecutorial plea bargain decision-making while providing
opportunity for future research.

Academic resilience, namely the ability of students to achieve academic success, even in situations that pressure and prevent them from achieving success. The reality on the ground shows that after implementing online learning, the level of student resilience tends to be low, so to overcome these problems, students need special guidance from counselors. This study aims to provide an overview of changes in student behavior in attending Onelin lectures after group counseling using assertive techniques. This research belongs to the type of quantitative research using class action methods. The subjects involved in this study were six students who experienced decreased resilience during the lecture process. Data collection in the study was carried out using observation, interview, documentation, and questionnaire methods. The data obtained in the study were then analyzed using percentage analysis techniques. The results of the research analysis showed that there was an increase in students' pre-test and post-test scores during the research cycle. The results show that 33% of students have high resilience in completing eight semesters of lectures, 50% have moderate resilience and can complete education in 9 semesters, and 17% have low resilience. These results then show that, in general, the application of group counseling assertive training techniques can significantly restore resilience in students, which is shown by the attitude of surviving and struggling to survive in various situations that interfere with the achievement of learning outcomes.

Currently, instrumental brain imaging plays a significant role in the examination of patients with cognitive impairment. It is important for diagnostic process, prognosis of the course of neurodegenerative, cerebrovascular and other diseases, clarification of the role of individual brain structures and systems in the development of cognitive and other neuropsychiatric disorders.

The purpose of the study was to analyze the volumes of the medial temporal lobes (MTL), hippocampus and brain volume in middle-aged patients with pre-mild cognitive decline.

Material and methods. 38 patients (33 women, 5 men) of middle age (60.77 ± 9.4 years) were examined. Patients were divided into two groups: with subjective cognitive decline (SCD) – 15 patients, aged 53.5 ± 6.94 years and subtle cognitive decline (StCD) – 23 people aged 63.35 ± 8.64 years (groups statistically did not differ in age). All patients underwent a neuropsychological examination with an assessment of the cognitive sphere, magnetic resonance imaging of the brain, including the assessment of the presence and degree of microangiopathy (MAP), morphometry of the medial temporal lobes, hippocampus, brain volume and a study for the presence of the allele of the apolyprotein E gene (ApoE4).

Results. A decrease in the average and total hippocampal volume was found in patients with StCD compared to patients with SCD. Also, MAP was significantly more common in patients with StCD. There were no differences in the degree of MTL atrophy. A decrease in the volume of the left hippocampus was revealed in patients with aggravated heredity for dementia. The average and total volume of the hippocampus is reduced in carriers of the ApoE4 allele of the apolyprotein gene. Correlation analysis showed the relationship between the average volume of the hippocampus and the volume of the brain.

Treatment of patients with facial neuropathy (FN) is a big scientific problem. There is no single protocol and patient management tactics are different. We have conducted an analysis of clinical practice in the treatment of patients with FN.

Material and methods. An anonymous online survey of neurologists positioning themselves as supporters of evidencebased medicine was conducted (n = 139, work experience – 5 [3; 10] years). It included 10 questions. The analysis of methods of treatment was carried out. We compared the experience of specialists, who prescribed a certain drug, and who did not prescribe it. Descriptive statistics are given in the form of: absolute (n) and relative values (%), medians (Me), lower [q1] and upper [q3] quartiles.

Results. In the studied sample with FN, all doctors recommend glucocorticosteroids, of which almost 2/3 allow use only in the first 3 days of the disease. Antiviral drugs are prescribed by 91.4% (n = 127) of specialists, the main indication is the presence of herpetic infection in visual examination (n = 104; 74.8%), less often a positive test for herpes infection (n = 23; 16.5%) or prosoplegia (n = 16; 11.5%). Anticholinesterase agents are prescribed by 38.1% (n = 53) of neurologists, their work experience is greater – 7 [5; 13] versus 5 [2; 9.75], p = 0.035. More than half (n = 81; 58.3%) of doctors do not recommend medications for additional drug therapy. Botulinum therapy is considered in the clinical practice of treatment of FN by 59% (n = 82) of doctors, regardless of work experience (p = 0.697), however, we observed a large variability of opinions according to the indications for use. When deciding on referral for surgical treatment, the most important doctors considered the problem of poor awareness of the types of operations (n = 83; 59.7%), as well as the lack of clear indications for surgical treatment (n = 62; 44.6%).

Conclusion. The study revealed a diversity of opinions even among specialists who position themselves as supporters of evidence-based medicine. There is a great need to develop Russian clinical guidelines for facial nerve neuropathy.

Published: July 2023

Картофель — это та культура, которая в течение вегетации нуждается в постоянных профилактических и санитарных обработках. Биологическая система защиты растений является одним из основных элементов, позволяющих снизить пестицидную нагрузку на агроландшафты и получить высококачественную продукцию. В полевых условиях Волгоградской области испытан комплекс биопрепаратов, производимых компанией «Биотехагро» (Россия), включающий обработку клубней картофеля сорта Гулливер перед посадкой и растений в течение вегетации против болезней и вредителей. Перед закладкой опыта были отобраны почвенные образцы, проведен микологический анализ, результаты которого установили наличие микромицетов с различной трофической специализацией, что, в свою очередь, скорректировало кратность проведения защитных мероприятий. Сравнительная оценка биологической и химической систем защиты при 2 режимах орошения показала, что использование биопрепаратов способствовало повышению полевой всхожести, снижению заболеваемости картофеля и повышению урожайности на 10,6 %.
Review paper- Liquid Robots: Studying recent technologies
Authors: Prasad Bhavya
Published: July 2023

Soft robots is a subfield of robotics where instead of the rigid features of a typical robot we have a robot made of soft materials like liquid, gel, soft materials. Although this field is advancing rapidly but the recent trends have to get improved further as they could be harmful to use and the way to use it rightly and make it better is the main thing here. Through this paper we would like to suggest methods and ways which could lead to break through in this field. We have learnt about the discovery and what suggestion we can give like, if the robot is able to pass through the jail bars of particular spacing length then what about if it could be shortened to such a space that it could go to an atomic level, which is something intriguing. Conclusion is that the trends in this field have been great but discovery is at a primitive stage as it needs much attention, we have given our suggestions on what we think could be more possible here.
Integrating Inquiry and Learning Community in Teaching Speaking: An Experimental Study
Authors: Sarinauli Barep , Sabirin
Published: July 2023

Language performance is the output of an individual’s language learning. In specific, speaking may serve as an indicator of students’ language skills. Second graders at a private secondary school, Maqamam Mahmuda, Takengon, Indonesia, had poor proficiency in this skill, particularly in English, with a median score of 34. The inefficient teaching and learning methods were to blame for this low achievement. As a result, it was proposed that a focused approach to the learning process be used. This study aims to determine whether integrating the inquiry and learning community may improve students’ English-speaking skills. It is expected to encourage students’ engagement in a learning group, predominantly speaking. In detail, the study focuses on how appropriately students perform in simple dialogue and monologues, and personal recounts following social function, general structure, and appropriate and contextual language elements. An experimental strategy using a one-group pretest and post-test design was employed to accomplish the study’s objective. Twenty pupils were randomly chosen as the treatment sample from a total population of 58 students. The outcome demonstrates that the students’ comprehension and pronunciation of English were significantly enhanced, from 34 to 60. The finding promotes the approach as a positive way to enhance students’ interest, comprehension, and confidence to speak in classroom interactions.

Implicature is the study of how to understand the speaker’s meaning which is stated indirectly. This study deals with conversational implicature found Paper Towns movie script in John Green’s movie. The objectives of the study are to analyse the types of implicature used in the debate and to explains the ways of performing implicature used by the characters. The qualitative research was used in this research. Grice’s conversational implicature (1975) was applied in analysing the data. The result showed that there were two types of conversational implicature used by the characters, namely: generalized conversational implicature and particularized conversational implicature. There were 4 generalized conversational implicature and 16 particularized conversational implicature. It was found four violations of maxims namely maxim of quantity, maxim of quality, maxim of manner, and maxim of relevance. Margo mostly violated relevance maxim. Through the implicatures the characters tried to convince the hearers, hide some information, keep a secret, express feeling and reject invitation.
Kiribati Game Development: Cultural Transmission, Communities of Creation, and Marketing
Authors: Voogt Alex
Published: July 2023

The people of Kiribati play a broad assortment of card and board games. The game rules show several innovations that were made outside the purview of the games’ manufacturers. The presence and regional development of proprietary board games illustrates product development scenarios that are counterintuitive to marketers. Using game boards and game rules collected in Kiribati, this study offers an explanation on how game development in Micronesia can be understood using cultural transmission theory by locating the Republic of Kiribati both geographically and economically within the Pacific Islands economies and their communities and within their own anthropological context. The findings emphasize the importance of understanding regional and country-specific cultural practices when applying principles of product development, placement and distribution.
The Specialization and Semantics Interpretation of Teacher Talk of Civil Engineering English MOOC In China: The Legitimation Code Theory Perspective
Authors: Dai Fengju , Chengyu Liu
Published: July 2023

With the economic development of China, the need for Civil Engineering talents with English language skills is continuously increasing. To meet this need, Civil Engineering English teaching plays a significant role. This paper takes the Civil Engineering English MOOC provided by a university located in eastern China, as an example, and takes two dimensions of the Legitimation Code Theory, specialization and semantics to investigate the following research questions: (RQ1) What are the textual semantic features, specialization and semantics characteristics of the selected Civil Engineering textbook? (RQ2) What “unpacking” strategies does the teacher adopt in the teaching process and what are the textual semantic features, specialization, and semantics characteristics of teacher talk in the MOOC? (RQ3) From the perspective of specialization and semantics dimensions, are there any deficiencies in this MOOC? The purpose is to analyze the “unpacking” strategies in teacher talk and the possible problems in the teaching process. The content analysis method is employed, and the data include two aspects: one is the textbook the MOOC adopted; the other is the teacher talk. Through the analysis, we draw the following conclusions: the teaching material shows the characteristics of high lexical difficulty and high semantic density; in the teaching process, the teacher, who works as an “intermediary”, mainly adopts “unpacking” strategies such as transforming knowledge code into knower code, improving learners’ knowledge code, and reducing semantic density. However, some defects such as the lack of knower code in teaching content, semantic wave fracture, and the weak comprehensibility of the input content make it difficult to achieve the teaching goal of mastering the elite code. Given these defects, this paper tentatively puts forward some suggestions based on the adopted theory.

Published: July 2023

Writing is one of the difficult skills in a language. The difficulty of writing includes spelling, punctuation, word choices, and so on. However, many students already studied writing since middle school. As a result, many of them have not yet been able to write correctly. The aim of this paper is to find out an increase in descriptive writing skills by utilizing a concept map. This study used descriptive and quantitative research on car design. The sample was 20 students using purposive sampling. The instrument was an objective test. The procedure for collecting data used to test distribution and analysis data. The finding showed that students had excellent to very good achievement in writing skills through concept maps. It was indicated by the results of the mean score in the post-test.  it indicates that the student’s writing ability was in good to Very Good criteria. It means that writing a descriptive text with a concept map was better than writing descriptive text without a concept map. This research found the pedagogical implication that concept maps help teachers in providing active learning, creative, effective, and fun for students according to learning style. Newly, it can increase awareness of teachers on students’ learning difficulties and efforts to overcome their obstacles in writing.

Speaking skill is an ability of oral communication owned by the students and requiring self-confidence in front of the people. Besides, speaking in English language is challenging for the students. It will arise their nerves and become anxiety.  This research was aimed to figure out the correlation between students’ learning anxiety and speaking skills at lower secondary school. It used quantitative method with correlation design. The data were obtained using questionnaire (FLCAS) for students’ learning anxiety and an English test for speaking skills. The questionnaire was adapted from Horwitz et al. (1986) to discover the students’ learning anxiety. The data was analyzed using SPSS Program in version 25. The population was all the students in the second grade with 102 students, and there were 41 students chosen by simple random sampling as the respondents. The result showed that Hi was accepted and H0 was rejected (0.046 < 0.05). Thus, there is a correlation between students’ learning anxiety and speaking skills
The educational and parenting test for home-based childcare: a socially valid self-rating instrument
Authors: Baumeister Antonia Elisabeth Enikoe , Jacobsen Julia , Rindermann Heiner
Published: July 2023

Introduction

Home-based childcare is increasingly becoming the focus of research, policy and public interest. Self-assessment of quality can increase the social validity of quality improvement efforts among stakeholders. A new online self-assessment tool for parents and non-relative providers of home-based childcare is introduced that has been developed in Germany, the Educational and Parenting Test for Home-Based Childcare (EPT; in German: ‚Bildungs- und Erziehungstest für TagesElternBetreuung BET‘).

Methods

In two studies, the social validity of the EPT was investigated: a stakeholder study with 45 parents and 12 non-relative caregivers, and an expert study with nine experts of child pedagogy. The stakeholders rated the EPT survey (N = 57) and the subsequent report of test results (n = 22). The experts evaluated the survey and the feedback report based on vignettes of three fictitious test results (i.e., below average, average, and above average quality). Criteria included face validity, measurement quality, controllability (i.e., comprehensiveness), freedom of response, freedom of pressure, counseling quality, usefulness, control of bias, and privacy protection.

Results

Most aspects of social validity achieved good to very good ratings. All three samples graded the EPT survey as “good.” If the stakeholders felt that their educational quality was undervalued, they rated the report of test results worse (rs(20) = 0.52, p = 0.02). Five of seven experts would recommend the EPT to others.

Discussion

Based on participants’ comments, the instrument was thoroughly revised. The EPT is a socially valid instrument for assessing and developing quality in home-based childcare.
The role of host pigments in coral photobiology
Authors: Ferreira Gabriel , Bollati Elena , Kühl Michael
Published: July 2023

Corals have the ability to synthesize various pigments, responsible for their characteristic vivid coloration. Most coral host pigments are green fluorescent protein (GFP)-like pigments exhibiting diverse spectral properties covering almost the entire visible spectrum, with pigments fluorescing from cyan to red. The type of pigment a coral can synthesize varies inter- and intraspecifically. However, the precise role of host pigments in coral biology has not been fully elucidated. Host pigments have the ability to modify local light fields and could thus contribute to optimizing the light exposure of the photosymbionts. Such fine-tuning of the light microenvironment could enable the holobiont to adapt to broader environmental conditions. Putative mechanisms include energy transfer between host pigments, as well as modulation of their scattering properties via tissue plasticity and granule formation that affect the distribution and organization of host pigments in coral tissue. These mechanisms can enable either photoprotection or photoenhancement depending on the coral’s environment. In this review, we summarize and discuss current knowledge about the link between host pigments and symbiont photosynthesis in reef-building corals, and discuss limitations and challenges of experimental investigation of this connection.
