Published: August 2024

Physical activity (PA) levels of community-dwelling adults aged 60 and over were assessed in Greece, in order to determine age and gender effects. PA was assessed using the PA Scale for the Elderly in 591 persons (287 males and 304 females), (Ã=74.04, SD=5.46). Participants were assigned into two age groups: A=65-75 and B=76-86 years. According to two way ANOVA, no significant differences were reported in total PA between men and women (p>.05) even though a significant age effect was reported with participants in Group A having higher scores than participants in Group B (p<.001). Men reported greater participation in recreational activities of moderate intensity (p<.001) and in exercises for muscular strength and endurance (p<.05). Women were more active in PA related to household (p<.001). Age effects resulted in favor of older adults in Group A 61-70 years when compared to older adults in Group B for walking, for recreational activities and for housework (p<.001). In conclusion, both gender and age affect PA participation of older adults in Greece.
RELATIONSHIP BETWEEN MORPHOLOGICAL CHARACTERISTICS AND MOTOR ABILITIES OF BOYS AND GIRLS AGED FROM 11-14 IN THE PROVINCE OF VOJVODINA
Authors: Beretić Igor
Published: August 2024

The aim of this study was to examine the relationship between morphological
characteristics and motor abilities of boys and girls aged from 11 to 14 so that the process of
physical education could be in line with the dynamics of growth and development as well as
the differences between the sexes. The total sample consisted of 730 subjects, divided into
four age groups of 11, 12, 13 and 14. Eight motor tests were conducted and 9 anthropometric
measures were taken. The boys of all ages achieved better results in tests of coordination, repetitive and explosive power, while girls of all age groups scored better in flexibility tests. The largest differences between the sexes at the ages of 11 and 12 years were the results of
variables evaluating motor abilities. At the age of 13, a significant difference in skinfold
thickness was found in favor of girls and at the age of 14 in the voluminousness in favor of
boys. In boys aged from 13 and 14, the increase in body volume was negatively correlated
with the increase in skinfold thickness, indicating that the increase of voluminousness is
caused by the increase of muscle mass. It is therefore concluded that the linear increase of the
differences in motor performance tests under 14 years of age is caused by increased muscle
mass in boys, especially in tests where achievement depends on the strength and production
of force.

Authors: Javorac Dejan
Published: August 2024

The aim of this paper is to establish the effects of an experimental treatment, so called
ìRussian complexî on explosive leg power of the basketball players belonging to the
experimental group. Explosive leg power was measured on the sample consisting of 40
basketball players from the Serbian league: 20 basketball players from the experimental group
and 20 from the control group, all aged between 16 and 18. The experimental group was the
subject of the experimental treatment, so called ìRussian complexî, which included gym
exercises and took place twice a week during the period of ten weeks. The results of the
univariate analysis of covariance indicated that the experimental programme led to a
statistically significant improvement of all three motor variables used for the evaluation of
explosive leg power (Sargent Jump Test, Standing Triple Jump and Standing Jump) in the
experimental group of examinees, in comparison to the control group. 
Heart rate changes (HR) and oxygen saturation in blood (AO2) dependency in relation to the static apnea duration (STA)
Authors: Pedja Tutorov Ognjen
Published: August 2024

In static apnea discipline diver holds the breath in standstill condition. Diving
reflex represents a reaction of the body to apnea dive with responses of effectors:
bradycardia, peripheral vasoconstriction, splenic contractions. Physiological significance
of these body changes implies reduction of oxygen consumption. The main objective of
this research is to examine characteristics of connection between heart rate changes (HR)
and changes in oxygen saturation in blood (SaO2) during apnea. A group of 15 breath
hold divers was examined. Tests were conducted during static apnea, heart rate (HR) was
measured as well as oxygen saturation in blood (SaO2). The changes in HR and SaO2
during apnea demonstrated statistically significant correlation. Higher HR values in apnea
indicate higher mental tonus during apnea which is followed by higher muscle tonus. The
consequence is a greater consumption of O2 and lower values of SaO2min. There is
statistically significant correlation between intensity of diving reflex activation and
oxygen conserving (less reduction of SaO2).

Authors:   Ternopil Volodymyr Hnatiuk National Pedagogical University, RUDENSKYI Rostyslav
Published: August 2024

The article substantiates that board games are a means of ensuring an organic transition from the social role of a pre-schooler to a new one – that of a primary school student. It is actualized that the educa-tional potential of board games in science is still under-researched both at the theoretical, practical, and methodi-cal levels. The educational potential of board games for children of senior preschool and primary school age is defined as a complex of essential characteristics (goals, motives, con-tent, means, techniques, results, integration) of forming a harmoniously developed personality of a preschool and primary school student in a purposeful educational pro-cess. It is noted that the selection of content for games should be in accordance with the general didactic criteria, requirements, and principles of preschool and primary education, aimed at implementing the basics of science, their holistic reflection in an available game printing form for children aged 5–10. The following characteristics of board games for chil-dren are substantiated: they are based on interactive players’ interaction (an internal volitional mechanism formation for self-regulation in the game process); they are an emotionally rich, dynamic, cultural, and leisure social practice (game as a leading activity, game as a significant form, game as a social function); an integrated didactic tool aimed at implementing the State Standard of Pre-school’s and Primary School’s Education content; a holis-tic resource for cognitive mental processes’ development (thinking, speech, memory, imagination, perception, atten-tion, etc.). The following groups of board games for chil-dren aged 5–10 years are systematized and analysed: for logical and mathematical development and education of sensory culture; creative imagination and creativity devel-opment; intellectual and emotional sphere development; cognitive mental processes development (thinking, speech, memory, attention, imagination); single-subject oriented and integrated, etc. It is summarized that board games for children of sen-ior preschool and primary school age have a long socio-historical development character; they are sustainable organic cultural leisure form; can be the subject of positive and negative socio-economic, worldview and ideological reflection of topics, events, actions, ideas; the emotional and volitional sphere formation tool of preschool and primary education through the culture of game behaviour adoption with printing sets, etc.
A method for calculating natural lighting in school classrooms with a solid cloudy sky
Authors: Shmarov I. A. , Zemtsov V. V.
Published: August 2024

The proposed method for calculating natural lighting in school classrooms makes it possible to more accurate calculate the illumination, taking into account the complex geometry of the premises and the characteristics of the cloudy sky. It is known that the presence of natural light strengthens the immune system and the psychological state of pupils. Taking into account the distribution of brightness across the sky makes it possible to more accurately calculate the luminous flux entering the room. The results of calculations are presented in the form of graphs, diagrams and visualizations that make the information clear and understandable. It is shown that taking into account the uneven distribution of the brightness of the firmament in cloudy skies makes it possible to more accurately calculate the luminous flux entering the school classroom through window openings and gives higher results (at least 10% than the calculation using the traditional method of SP 367.1325800.2017 “Residential and public buildings. Rules for the design of natural and combined lighting”).
The Great Game and the border issue in the Pamirs in the reports of Ralph Cobbold, 1898‒1899
Authors: Bukharin Mikhail D.
Published: August 2024

The 1890s were a time of growing tension in Central Asia, stemming both from the geopolitical confrontation between the Russian and British empires and from the desire of Afghanistan and China to realise their own national interests and use the struggle of the dominant political forces to their own ends. One of the most difficult issues was the border dispute, i.e. fixing the border between Russia and Afghanistan, on the one hand, and Russia and China, on the other. Britain sought to exploit the differences on this issue to its own advantage, which could well have led to the outbreak of hostilities. The mechanism for identifying weaknesses in Russia’s position in the Pamirs comes out clearly in the 1898‒1899 reports of the British intelligence officer Ralph Cobbold, preserved in the National Archives of India. They characterise the actions of the Russian authorities in the Pamirs, the attitude of the local population to the opposing sides, and potential instruments of local influence that would allow Britain to bring the region under its control. The Russian diplomatic and military administrations were aware of the aspirations of the British Empire and used both the “stick” and the “carrot” to maintain the status quo in the region: in some issues they had to make concessions, in others the Russian side acted rigidly. Such an approach not only kept the Central Asian region in the frames of peaceful development, but also was one of the foundations of the conclusion of the Russian-British pact on the division of spheres of influence in the Middle East and Central Asia in 1907, which put an end to the Great Game and allowed the formation of the Triple Anglo-Franco-Russian alliance.
The role of the “history effect” in the formation of the expected result in the problem-solving process
Authors: Medyntsev А. А.
Published: August 2024

The article presents the results of a study of the development of mental regulation of students’ psychological states during their studies at a university. This work is based on authors’ conceptual model of the structural and functional organization of psychological states’ mental regulation. The study was carried out at the initial and final stages of students’ education in everyday and stressful situations of academic activity covering the period from 2019 to 2023. Methods and effectiveness of psychological state self-regulation were studied using well-known valid methods and specially designed questionnaires. Mental structures such as reflection, life meaning orientation, and self-system, as well as individual regulatory properties studied outside educational situations in first (2018) and fourth years (2022) of study were investigated. As a result of the study, it was established, that, regardless of the situation of educational activity, psychological states acquire greater stability (equilibrium) by the senior year of study, which is associated with the effectiveness of states’ self-regulation. Changes in mental structures from the initial course to the final of study are revealed in an increase in the intensity of their manifestations in all main indicators. It has been established that in both situations, during the learning process, students experience an increase in the involvement of mental structures (primarily reflexive) and regulatory properties in the regulation of psychological states. In each situation of educational activity and at each stage of training, there were identified the leading structures of consciousness, determining the choice of self-regulation methods, which, in turn, are associated with the substructures of psychological states. It has been also stablished that from the initial stage of study to the final one, there is an increase in the number of methods used for states’ self-regulation, as well as their relationships with mental structures and regulatory properties of the personality, which indicates the development of a system of mental regulation of students’ psychological states.
Taxonomic Status of the Far Eastern Cattail Typha japonica (T. sect. Ebracteolatae) in the Context of Its First Record in Russia

Published: August 2024

Japanese cattail (Typha japonica Miq., section Ebracteolatae) has been restored to its valid taxonomic status and listed as one of the floras of the outmost southern Sakhalin and Kuril Islands for the first time. These are the first records of T. japonica in Russia. With the unique geography and current molecular data (rpl32-trnL intergenic spacer), the latter cattail’s combination of morphological characters clearly distinguishes it from all other species of sect. Ebracteolatae (including T. caspica, T. elata, and T. tzvelevii), and also from all currently known bract-less species of Typha, including the Eastern cattail (T. orientalis C.Presl.), with which T. japonica was arbitrarily synonymized previously.
Early Detection of Contamination with Microplastics by Changing the Phototaxis of Freshwater Mesozooplankton to Paired Photostimulation

Our previous studies showed that the change in the plankton response to light could be an indicator of environmental pollution. This study experimentally reveals that the response of Daphnia magna Straus and Daphnia pulex plankton ensembles to photostimulation depends on the intensity of the attracting light. This makes it difficult to identify the occurrence and change of pollutant concentration. The large variability in the magnitude of the behavioral response is caused by the nonlinear response of plankton ensembles to the intensity of the attractor stimulus. As the intensity of the photostimulation increases, the variability of the phototropic response passes through increase, decrease and relative stabilization phases. The paper proposes a modification of the photostimulation method — paired photostimulation involving successive exposure to two photostimuli of increasing intensity. The first stimulus stabilizes the behavioral response, while the increase in response to the second stimulus makes it possible to more accurately assess the responsiveness of the plankton ensemble. The study demonstrates good reliability and increased sensitivity of this method of detecting changes in environmental toxicity compared to single photostimulation or traditional bioindication through the survival rate of test organisms.

Pengaruh Pemberian Vitamin E Dengan Dosis Yang Berbeda Pada Pakan Terhadap Pemijahan Lobster Air Tawar (Cherax quadricarinatus)
Authors: Nusi Vina adelia , Juliana Juliana , Suherman Sutianto P.
Published: August 2024

Freshwater lobster (Cherax quadricarinatus) is a type of lobster that has the potential for developed as a cultured organism. The problem that often occurs is the low number of freshwater lobster production due to the relatively long reproductive time. Vitamin E is a nutrient that plays a role in improving the spawning process in animals. This research aims to determine the effect of vitamin E to artificial feed at different doses on spawning. The test animals used were 16 female freshwater lobsters measuring 4 inches, aged 6 months, with an average weight of 30-55 grams. The research was conducted over 60 days using an experimental method with a completely randomized design (CRD) consisting of 4 treatments with 4 replications each. Treatment A was without vitamin E, Treatment B had 250 mg/kg of feed, Treatment C had 450 mg/kg of feed, and Treatment D had 650 mg/kg of feed The results showed that the levels of gonad maturity, fecundity, degree of fertilization, egg hatchability, and survival rate were not significantly different among treatments. However, Treatment C yielded the best results, with a gonad maturity level of 10.60%, fecundity of 281.53 eggs, a fertilization rate of 8.59%, a hatchability rate of 62.50%, and a survival rate of 100%. Data analysis was conducted using analysis of variance (ANOVA) at a 95% confidence level. The results indicate that the addition of vitamin E to feed at different doses does not significantly affect the spawning of freshwater lobsters.

Introduction: Mandibular fracture is a fracture that often occurs in maxillofacial trauma. Fracture locations most often occur in the parasymphysis region and combined angle- parasymphysis fractures. Multiple mandibular fractures usually cause facial asymmetry and are challenging to reduce. Fracture treatment must be carried out immediately to restore function and aesthetics. This case report aims to discuss managing multiple mandibular fractures in the angulus and parasymphysis regions of the mandible.

Case report: A 13-year-old male patient came to the emergency room at Hasan Sadikin Hospital with bleeding from the mouth caused by a two-wheeled traffic accident. Clinical and radiographic examination results revealed a fracture of the right para symphysis and left mandibular angle. The procedure carried out is Open Reduction Internal Fixation (ORIF).

Discussion: Mandibular fractures often occur, and the leading cause is usually caused by driving accidents. Clinical examination and radiographs are needed so appropriate treatment can be carried out. In this case, treatment involves open reduction internal fixation (ORIF) extra and intra-oral approaches. Installation of 2 mini plates each in the symphysis region and angle of the mandible.

Conclusion: Treatment for multiple fractures that occurred in the maxillofacial area, in this case, was internal fixation with open reduction (ORIF). The results of the treatment showed facial symmetry and normal chewing function.

We report new records for three potentially non-indigenous polychaetes in Italian waters. The Nereididae Leonnates aylaoberi Çinar & Dağli, 2013 is reported for the first time in the Tyrrhenian, Ionian and Adriatic Sea; this species has type locality in the Mediterranean Sea, but the genus Leonnates has Indo-Pacific affinity, and its distinctive characters suggest that it is a recent newcomer to this area. We here suggest that L. aylaoberi should be considered cryptogenic in the Mediterranean Sea. Moreover, we report the first records of Paucibranchia cf. adenensis Gravier, 1900 for the Italian coastline, in the Ionian and Tyrrhenian Sea, and the first records of Isolda cf. pulchella Müller, 1858 in the Tyrrhenian Sea. The meaning of the differences identified between the Mediterranean material and the available descriptions of these species is briefly discussed. Juvenile individuals of L. aylaoberi and P. cf. adenensis are also described for the first time.

Serangan jantung adalah kondisi akut medis yang memerlukan pertolongan dengan cepat dan tepat.  Pertolongan pertama pada serangan jantung harus diberikan secepat mungkin untuk menolong  jiwa. Basic Trauma Cardiac Life Support (BTCLS) adalah tindakan untuk memberikan pertolongan pada korban bencana atau kegawatan kardiovaskuler guna mencegah kematian atau kerusakan organ lebih lanjut. Resusitasi Jantung Paru (RJP) merupakan pertolongan medis untuk mengembalikan kemampuan napas dan sirkulasi darah yang terhenti karena kondisi atau situasi tertentu. Tindakan ini perlu dilakukan secara cepat dan tepat sebagai langkah awal menyelamatkan nyawa seseorang.  Tindakan RJP dilakukan oleh orang yang telah mengetahui dan  memiliki ketarampilan  melakukan RJP pada korban  kegawatan kardiovaskular atau henti jantung..  Keterampilan RJP  dapat diajarkan kepada siapa saja, termasuk siswa SMA juga bagian dari masyarakat dilatih untuk menguasai  dan terampil memberikan pertolongan pertama pada kegawatan kardiovaskuler.

Molecular Mechanisms of Drosophila Hematopoiesis
Authors: Sinenko S. A.
Published: August 2024

As а model organism, the fruit fly (Drosophila melanogaster) has assumed a leading position in modern biological research. The Drosophila genetic system has a number of advantages making it a key model in investigating the molecular mechanisms of metazoan developmental processes. Over the past two decades, significant progress has been made in understanding the molecular mechanisms regulating Drosophila hematopoiesis. This review discusses the major advances in investigating the molecular mechanisms involved in maintaining the population of multipotent progenitor cells and their differentiation into mature hemocytes in the hematopoietic organ of the Drosophila larva. The use of the Drosophila hematopoietic organ as a model system for hematopoiesis has allowed to characterize the complex interactions between signaling pathways and transcription factors in regulating the maintenance and differentiation of progenitor cells through the signals from the hematopoietic niche, autocrine and paracrine signals, and the signals emanated by differentiated cells.

The effects of the antioxidant dihydroquercetin (DHQ) were studied in a model of pulmonary fibrosis. DHQ penetration into the lesion was facilitated by encapsulation into liposomes. Pulmonary fibrosis was modeled in rats by intratracheal injection of bleomycin. For the first 7 days, the rats in the treatment group received a liposomal emulsion with DHQ, while in the comparator group rats received saline. In the control group, intact rats did not receive any exposure. Thirty days after the initiation, lung function and the pathological lesion volume were assessed by 7T 1H MRI and the lungs were taken for histologic examination. The proportion of fibrous tissue was counted by Masson’s trichrome staining. Both experimental groups were characterized by a significant functional pulmonary deficiency, with low mortality and a small lesion area. In the rats treated with DHQ, the distribution of fibrous tissue was significantly altered. Significantly more fibrous tissue was found in the center of the lesion, while significantly less was in the interstitial space of alveoli. Lung density at the same time was lower in the treated lungs. Dihydroquercetin encapsulated in liposomes affects the mechanisms of bleomycin-induced pulmonary fibrosis progression in rats. While accelerated fibrosis of the lesion can restrict inflammatory processes, delayed fibrosis of the interstitium can further improve the functional state of the lungs.

Anatomical visualization and molecular typing of tumor tissue of regional metastatic lymph nodes (mALN) in patients with breast cancer, it is an important clinical problem in modern oncology. According to the results of previous studies, the [99mTc]Tc-(HE)3-G3 has proven itself as a promising diagnostic agent that allows differentiating the status of the HER2/neu receptor of a primary breast tumor (p0.05, Mann-Whitney test). In this regard, the purpose of this study is to explore the possibilities of using [99mTc]Tc-(HE)3-G3 to type the status of HER2/neu in patients with breast cancer. The study was conducted on clinical material including 20 patients with breast cancer (T2-4N1-3M0-1) before the systemic therapy (10 patients with overexpression of HER2/neu in metastases of axillary lymph nodes and 10 patients with negative) who underwent SPECT/CT scan 4 hours after injection of [99mTc]Tc-(HE)3-G3. Morphological and immunohistochemical studies of tumor tissue of metastatic axillary lymph nodes were performed in all patients with an assessment of HER2/neu status. Based on the results of our analysis, we found that the use of the mALN -to-contralateral and mALN-to-LDMratios 4 hours after injection of [99mTc]Tc-(HE)3-G3 should be considered for typing the status of HER2/neu in mALN in breast cancer patients (p0.05, Mann-Whitney test). At the same time, for the low/background parameter, the sensitivity and specificity indicators were 80% with a threshold value 12.25.
