Modelling Skeletal Muscle Motor Unit Recruitment Contributions To Contractile Function: Part 2 — Total (aerobic + anaerobic) ATP Turnover
Authors: Davies Julia G. , Mulligan Lucy R. , Nygaard Gerhard , Holland Justin , Robergs Robert
Published: August 2024

The purpose of this research was to expand understanding of the energetics of skeletal muscle contractions through modeling the total ATP turnover (totATPto = aerobic + anaerobic) of different muscle fibre types and motor units. Contraction conditions involved varied motor unit recruitment for a single contraction, in addition to 3 min of repeated contractions across varying contraction frequencies (0.5 to 2.0 Hz in 0.5 Hz increments) and fractional motor unit recruitment (0.5 to 0.95 in 0.05 increments). Contractile power data was obtained from prior research of the vastus lateralis and converted to totATPto from the free energy release of ATP hydrolysis (50 kJ×M-1) and the cellular efficiency of free energy transfer from ATP hydrolysis during muscle contraction (40%). A computational model was then developed for totATPto for repeated contractions spanning 0.5 to 2.5 Hz and fractional recruitment of 0.5 to 0.9 across 4 different genetic expressions of slow twitch (ST; Type I and I - IIa) to fast twitch (FT; Type IIa, IIab, IIb) proportionality. Completion of 3 min of repeated contractions for 0.4, 0.65 and 0.9 fractional recruitment for the 2 extremes of motor unit proportions (%ST - FT = 80 - 20 to 20 - 80) for contractions at 1 and 2 Hz resulted in totATPto of 30.28 vs. 55.66 vs. 110.28 mmol·L-1 (0.4,0.65,0.9;80 – 20; 1 Hz); 50.24 vs. 130.51 vs. 275.58 mmol·L-1 (0.4,0.65,0.9;20 – 80; 1 Hz); 60.57 vs. 111.31 vs. 220.55 mmol·L-1 (0.4,0.65,0.9;80 – 20; 2 Hz); 100.49 vs. 261.03 vs. 551.16 mmol·L-1 (0.4,0.65,0.9;20 – 80; 2 Hz). The 0.65 fractional recruitment data most reflect prior in-vivo whole muscle research of totATPto data and reveal the construct validity of the model. Further modelling is needed to improve our understanding of the metabolic significance of motor unit recruitment to skeletal muscle cellular energy transfer during exercise.

Penelitian ini mengkaji tentang Evaluasi sistem hukum Indonesia dalam menangani cyberbullying berbasis teknologi informasi dan komunikasi. Tujuan dari penelitian ini untuk menganalisis sistem hukum di Indonesia menangani permasalahan cyberbullying serta menganalisis evaluasi terhadap kinerja sistem hukum dalam menangani cyberbullying berbasis Teknologi Informasi dan Komunikasi di Indonesia. Penelitian ini menggunakan jenis penelitian hukum normatif. Hasil penelitian menunjukkan bahwa sistem hukum belum efektif dalam menangani terjadinya kasus cyberbullying di Indonesia, sehingga perlu dilakukan evaluasi secara berkala agar dapat menangani cyberbullying efektif untuk kedepannya. Adapun dari hasil evaluasi ditemukan bahwa struktur hukum menghadapi hambatan terutama dalam menjalankan operasi di dunia maya. Hal tersebut disebabkan terbatasnya sistem yang dapat digunakan untuk melakukan patroli di dunia maya. Sehingga kedepannya penting untuk dipertimbangkan penggunaan techno prevention dalam mencegah terjadinya cyberbullying di Indonesia, sebab jika dalam menangani cyberbullying hanya terfokuskan pada penggunaan hukum pidana saja tidak akan efektif mengingat hukum pidana bersifat post factum sedangkan model dari cyberbullying kedepannya akan semakin bervariasi seiring dengan perkembangan teknologi itu sendiri.

Enhancing NDE Reliability for Grade 91 Steel Welds: Ultrasonic Imaging and Microstructural Correlations
Authors: Onwuama Obinna C. , Aryan A. , Na Jeong K. , Bourgeois Desmond , Zhang Wei
Published: August 2024

Ensuring the integrity of Grade 91 (9Cr-1Mo-V) steel welds is vital for the safe and reliable operation of fossil fuel–fired and nuclear power plants. This study applies an imaging technique for the ultrasonic characterization of two Grade 91 steel welds created with cold metal transfer and flux-cored arc welding processes. Ultrasonic immersion testing in the through-transmission configuration was employed to generate shear waves, which helped identify the weld metal, heat-affected zone, and base metal regions. These weld microstructures were also correlated to their ultrasonic images using metallography, ultrasonic amplitude, hardness measurements, and grain size. The findings from this study can assist practitioners in developing new nondestructive evaluation technologies, improving the inspection reliability of creep strength–enhanced ferritic steel welds by potentially identifying weld microstructure regions susceptible to creep-type failures.

Erectile Dysfunction as a Novel Biomarker for the Onset of Cardiometabolic Vascular Disease Risk in the Aging Male: A Systematic Review and Meta-Analysis
Authors:   Professor of Medicine (Endocrinology and Clinical Nutrition) Independent Medical Scientist, Brazil, Julian, Y.V. Borges
Published: August 2024

Background and Objectives: Vascular Erectile dysfunction (ED) is considered a sentinel marker for underlying cardiovascular and metabolic disorders. This systematic review and meta-analysis aim to quantify the correlation and the predictive value of ED for cardiometabolic vascular diseases (CVD) in young adults as well as aging males and to explore the temporal relationship between ED onset and the development of these diseases. Methods: A comprehensive search of databases including PubMed, EMBASE, and Cochrane Library was conducted to identify relevant studies. Inclusion criteria were studies assessing the association between ED and CVD, with effect sizes reported as odds ratios (ORs) or hazard ratios (HRs). Data were extracted and pooled using random-effects metaanalysis. Sensitivity analyses, including leave-one-out analysis, and Egger’s test for publication bias, were performed. Findings: The pooled analysis of 39 studies revealed a significant association between ED and CVD with an OR of 1.42 (95% CI: 1.28-1.57). The temporal relationship indicates that ED precedes the onset of CVD by approximately 2 to 5 years. Endothelial dysfunction, a common pathway in ED and CVD, was highlighted through biomarkers such as flowmediated dilation (FMD), nitric oxide (NO) levels, and C-reactive protein (CRP). Limitations: Limitations include heterogeneity among study designs and the potential for residual confounding. Conclusions: ED is a robust predictive biomarker for CVD in aging males, with significant implications for early detection and preventive strategies. Clinical Implications: Clinicians should consider cardiovascular risk assessment in patients presenting with ED to facilitate timely intervention and improve long-term outcomes.

Authors: Bocharova Yu. H. , Ishchenko O. V. , Bilakovska A. D.
Published: August 2024

Objective. The objective of the present study is to analyze the level of economic security in general and foreign economic security of Ukraine in 2010-2021, in particular, to identify disincentive factors and stimulators of foreign economic security in 2010-2022.

Methods. The following methods and techniques of cognition are applied: analysis and synthesis, induction and deduction (to justify the complementary relationship between economic and foreign economic security), analysis of series of dynamics (to identify the state and trends inherent in indicators of economic and foreign economic security of Ukraine), tabular (for visual presentation of factual data on the level and dynamics of economic and foreign economic security of Ukraine in 2010-2021 and 2010-2022, respectively ).

Results. On the basis of the conducted study of the level of economic security in general and external economic security of Ukraine in 2010-2021, in particular, it is determined that during the period under the analysis, the level of economic security of Ukraine was on average 40%, foreign economic security – 35%, which corresponds to a dangerous state. At the same time, foreign economic security is proposed to be considered as the state of protection of the country's national economic interests in the field of foreign economic relations, which is based on the country's ability to ensure sustainable economic growth and increase the welfare of the population in the long term; protect their national resources and markets from external threats; influence world economic processes and defend their interests in the international arena. It is identified that the factors stimulating foreign economic security of Ukraine in 2010-2022 were: high level of openness of the economy; the specifics of export-import operations – the value of exports significantly exceeded the value of imports, a high level of focus on one geographical direction was observed – one foreign trade partner, one product; low level of processing of goods and specialization in trade in raw goods with a low level of processing; low level of utilization of the transit capacities of the gas transportation and oil transportation system; sufficiently high level of import dependence; insufficient level of diversification of the economy. It is determined that despite the lack of factors stimulating the country's foreign economic security during 2010-2022, the following positive trends are observed during this period: decrease in the openness of the national economy, decrease in the level of foreign trade dependence of Ukraine on leading partner countries, decrease in the level of dependence on export volumes countries from the leading product (product group).
FOOD SECURITY: DEFINITION AND EVOLUTION OF THE CONCEPT
Authors: Stashkevych I. O.
Published: August 2024

Objective. The objective of the article is to study the evolution of the concept of «food security» and to substantiate the feasibility of forming new approaches to its definition.

Methods. The study uses general scientific and research methods: theoretical generalization and comparison (to summarize the definitions of approaches to understanding the essence of the concept of «food security» and changes in the definition of «food security» from the Food and Agriculture Organization (FAO), analysis and synthesis (to determine the factors influencing the change in the concept of «food security»), systematization of definitions (to determine similar views of scientists).

Results. The article examines the concept of «food security» as an important socio-economic category that has been transformed over the millennia, reflecting the means of preserving humanity from hunger to meet individual needs at the present stage of development and summarizes its definition.

Comparing the definition of «food security» according to the FAO and leading scholars such as Megan Carney, Raj Patel, Shenggen Fan and others, it is necessary to emphasize the areas in which this concept is considered and supplemented, namely social justice, economic development, sustainable agriculture, environmental sustainability, etc. Scientists emphasize that food security is not limited to physical access to food, but also includes the right kind of food, social justice in the distribution of resources and access to them, and the need to preserve the environment.

That is, on the one hand, food security is a broad enough concept to be globally oriented, taking into account the needs and conditions of different countries and regions of the world, and on the other hand, at the individual level, it reflects physical, social, and economic access to safe and nutritious food for any person in any time of need, which meets dietary needs and food preferences, which, in turn, ensure an active, fulfilling and healthy life.

Thus, the FAO's definition of food security is more general and globally oriented, while the views of the scientists considered in the research provide a more specific and comprehensive approach. In order to address the issue of food security effectively it is important to take into account not only physical access to food but also a wide range of social, economic and environmental factors.

Published: August 2024

The textile industry consumes a lot of water during production and generates a massive amount of effluents, including synthetic dyes, into the environment, which raises public concern. Azo dyes that are predominantly utilized in the textile sector are regarded to offer serious health hazards. Jute sticks are a typical fuel source in Bangladeshi villages. After using jute sticks as fuel, we turn them into highly cost effective activated charcoals which are capable of removing Levafix Amber (most used azo dye) from textile effluent. In this article we reported for the first time a cost effective, ecofriendly jute stick extracted adsorbent for the removal of Levafix Amber dye from textile effluents. The most notable benefits of our approach are its low cost, simplicity, and lack of the need for costly instruments.

A computational DFT study of Imidazolium based Ionic liquids: binding energy calculation with different anions using Solvation Model
Authors: Dhar Kalyan , Biswas Jagannath , Arabi Ishmam Ibnul , Alam Md Shariful , Rahman Md Mahbubur
Published: August 2024

Basic knowledge of chemical events in the gaseous or liquid phase, as well as on surfaces, is required to determine the macroscopic process. The structure of ionic liquids were investigated using quantum chemistry. Cation and anion can bond together, according to the findings. Their binding and interaction energies reveal that they are produced by hydrogen bonds. The mechanism of a room temperature ionic liquid, such as [BMIM][Cl] (1-butyl-3-Methylimidazolium chloride) monomer, was studied using Density functional theory (DFT) computations using the modern continum solvation model (IEFPCM-SMD). Ionic liquid [IL] contains both anions and cations, allowing for greater intermolecular interactions. By analyzing the relative minimum energy of [BMIM][Cl] in the presence and absence of water, we were able to establish the minimum energy structures and probable Cl anion binding sites in [BMIM][Cl] ionic liquid. We have found that all 1-butyl-3-methylimidazolium halide ILs investigated had  trans conformations due to the butyl group’s dihedral angles.

Joint models for longitudinal data
Authors: WU LANG , GAO SIHAOYU , YE QIAN
Published: August 2024

In a longitudinal study, data on different types of variables are often collected repeatedly over time. Some variables may be continuous, and some variables may be binary or times to an event of interest. Even for a single variable, data may be collected at different phases of the study with different characteristics. These different types of variables are typically associated or correlated, since they are measurements on the same individuals in the study. Analysis of data on each of these variables separately, ignoring other variables, may be inefficient and may also lead to biased results. Standard multivariate models with several correlated responses may not be easy to specify for different types of variables or when the models are nonlinear. Jointly modelling these variables simultaneously not only may be more efficient but may also reduce biases in parameter estimation. Statistical inference can then be based on the joint likelihood for all observed data. In this article, we briefly review several different types of joint models for longitudinal data. We focus on mixed effects models and likelihood methods for inference. We illustrate these joint models with datasets from HIV/AIDS studies.

Current Management of Warm Autoimmune Haemolytic Anaemia and Recent Advancements in Research: Interview with a Key Opinion Leader
Authors: Scott Brigitte
Published: August 2024

Warm autoimmune haemolytic anaemia (wAIHA) is a rare, life-threatening disorder caused by autoantibodies that lead to the premature destruction of erythrocytes (haemolysis). There is currently no licensed targeted therapy for wAIHA. Until recently, there has been little research attention on autoimmune haemolytic anaemias (AIHA), with few developments in the field over the past 20 years. The last 3 years have seen a surge in research interest in wAIHA, with the development of potential new therapies for this rare disorder. For this article, the EMJ conducted an interview in June 2024 with key opinion leader, Bruno Fattizzo, from the University of Milan, and Fondazione IRCCS Ca’ Granda Ospedale Maggiore Policlinico, Milan, Italy, to raise awareness of wAIHA, and explore recent advancements in research on this disease. Fattizzo, who has a wealth of experience and expertise in the clinical management of wAIHA, provided valuable insights into topics such as the clinical and quality of life (QoL) impact of wAIHA on the patient; current management of wAIHA, including steroids, rituximab, immunosuppressants, splenectomy, anticoagulant prophylaxis, and recombinant erythropoietin; and remaining unmet needs in the disease area. Also discussed were potential future therapies for this autoimmune disorder, including tyrosine kinase inhibitors, neonatal fragment crystallisable receptor (FcRn) inhibitors, and B cell activating factor receptor (BAFF-R) antagonists, and the challenges involved in managing patients with wAIHA. Finally, Fattizzo described the patient experience of living with wAIHA, proposed how best to raise awareness of wAIHA among healthcare professionals, the scientific community, patients, and the public, and outlined what the future of the management of patients with wAIHA might look like.
Study of Ontogenetic Structure and Density of the Coenopopulation of Hedysarum atropatanum Bunge ex Boiss. Flora of Daridag
Authors: Heydarova A.
Published: August 2024

The article presents findings from a study of the demographic structure and density of the population of the species Hedysarum atropatanum Bunge ex Boiss., which is widely distributed in the Daridag area. A total of ten ontogenetic states (seed, seedling, juvenile, immature, virginile, young generative, middle aged generative, aged generative, subsenile and senile) of the H. atropatanum species were observed. The processes of ontogenesis, which can be classified as normal, fast, or slow, were identified as the primary mechanisms driving species evolution. Additionally, instances of developmental disruptions, rejuvenation, and the manifestations of aging were observed. The majority of individuals belonging to the species H. atropatanum exhibit a normal to rapid growth rate. It has been observed that the process of ontogenesis is slower in areas with high plant density. It was determined that the secondary quiescence period does not manifest during the initial stages of development; rather, it becomes feasible only after the individuals have reached the virginal state. It has not been observed that immature individuals bypass the virginal state and immediately transition to mature generative plants. The vitality status of the individuals was determined based on a comprehensive analysis of multiple morphological traits, including the height of the specimens, the number of shoots, the number of flower carriers, the length of the leaves, the size of the leaves, and the number of flowers in the flower group. Following the statistical processing of the data, three classes of vitality were identified. A study revealed that individuals of the second vitality level of the H. atropatanumspecies are more prevalent in the coenopopulation. The optimal habitats of the H. atropatanum s

Published: August 2024

Based on the ecological and geobotanical studies conducted in xerophytic (arid) sparse forests in the territory of Azerbaijan and the study of the relevant literature, a classification scheme was developed taking into account xerophytic tree species that form such groups as Caragana grandiflora DC. and Astragalus microcephalus Willd. In the course of the study, based on phytocoenological principles, a xerophytic (arid) sparse forest type of vegetation was noted in the Turyanchay Reserve, in the mountainous part of the Lankaran-Yardymli district, in Nakhchivan and the Gabala district located on the southern slope of the Greater Caucasus. It was established that this type of vegetation consists of 1 formation class, 2 formation groups and 2 associations. A geobotanical description and species composition of the formations was carried out and it was established that the sparse forests of Caraganeta-Pistacetum-Juniperosum, found in the leguminous shrubs, need protection from the negative impact of anthropogenic factors. And this, in turn, creates the basis for the conservation of plant formations found in the forest ecosystems of Azerbaijan.

As it is known, all living things constantly exchange food and energy with the environment in order to continue their life activities and participate in the ecological functions they perform in nature, and this situation is ecologically both producers (plants), consumers (animals), and reducers (fungi). and bacteria). Nevertheless, the dependence on the environment of consumers as well as reducers is a more sensitive feature than that of producers, since both of the latter, i.e., fungi and animals, are heterotrophs due to their nutrition, i.e., because they cannot carry out the process of photosynthesis, they depend on organic matter, as well as also, the demand for oxygen is met by another source, primarily plants. Due to the fact that plants play an important role in the provision of food for most living things, their comprehensive study has always been relevant and today it maintains that status in full force. As a result of the analysis of literature data, it is possible to state it in general data below.

Published: August 2024

The relevance of aerobiological topics is evidenced by the fact that from July 1 to July 5, 2024, an unusual event was held in Vilnius (Lithuania), including the 8th European Symposium on Aerobiology (8th ESA), the 12th International Congress on Aerobiology (12th ICA) and the 5th International Ragweed Conference (5th IRC). World Aerobiology 2024 is an event of unprecedented scale. It discussed the use of artificial intelligence (AI) for calculating and interpreting aerobiological monitoring data. But so far, AI cannot identify all taxa, so careful counting and identification of plant pollen and fungal spores is only possible for a human researcher. Aerobiological monitoring using volumetric traps remains the gold standard of research. In the world community, there are networks of biological monitoring of air quality with the study of the concentration of plant pollen and fungal spores in the air. Through an application on a mobile phone, you can find out the forecast of periods of maximum risk, during which patients with hay fever are exposed to the main aeroallergens. Popular queries from Internet users relate to the complex problem of climate change, environmental pollution and aeroallergens. There is no National Aerobiological Monitoring system in Kyrgyzstan, but the Meteonova service has launched a pollen forecast application for mobile phones, which is still in the testing stage and does not reflect the real features of the aerobiological spectrum. It is known that in the world there are more than 12,000 species in the Poaceae family, classified into 771 genera belonging to 12 subfamilies. In Kyrgyzstan, 300 anemophilous species of annual perennial plants grow, releasing a huge amount of pollen into the atmosphere in the spring and summer. Poaceae pollen is still one of the top ten global aeroallergens, being the leading cause of hay fever, by predominant size, classified as biological pollutants (PM10). The concentration of cereal pollen was consistently observed in the air of Karakol during all seasons of the study and ranged from 167 to 174 days. Its daily maximum concentrations were detected in June-July; the distribution of pollen in the air is unimodal. The influence of the anthropogenic triad on fluctuations in the concentration of cereal pollen was established: climate change (temperature) and land use systems, as well as environmental pollution, which manifested itself in the degradation of pollen grains and the appearance of damaged and unidentified biological particles. The purpose of this article is to study the concentration of cereal pollen in the air, their integrative contribution to the aerobiological spectrum in the city of Karakol as dominant pollen allergens.
Water-Salt Homeostasis of the Human Body and Electrolytic Composition of the Internal Liquid Environment
Authors: Seyidova L.
Published: August 2024

Maintaining water and salt balance in the body is important for the basic functioning of cells. It reduces the water level by increasing the urine production of the kidneys. During excessive salt intake, the blood absorbs water from the tissues and edema occurs. To prevent this, the kidneys increase the amount of urine. Excess salt is excreted in the urine. Blood pressure regulation is one of the most complex aspects of homeostasis. The adrenal glands, spine, and sympathetic and parasympathetic nervous systems work together to balance blood pressure and keep it at a healthy level. Changes in blood pressure are detected by receptors and the information is sent to the brain for processing. Blood pressure either rises or falls with the help of nerve impulses and hormones to the heart.
Structural Indicators and Productivity of Soybean and Sorghum Plants in Single and Mixed Sowing During the II Sowing Period in Sheki-Zagatala Region
Authors: Zamanova R.
Published: August 2024

The article describes the importance of mixed cropping as a resource-saving system and an innovative method of cultivating forage crops. The reason for the high productivity in mixed cropping is that the plants shade each other well on hot days, do not allow the moisture in the soil to evaporate quickly, and the plants effectively use this moisture, and the soybean legume absorbs free nitrogen from the soil and air and enriches the soil with nitrogen, thereby increasing the yield by fertilizing the sorghum roots. Thus, according to the results of research work on single and mixed soybean + sorghum sowing in the third decade of April in the Sheki-Zagatala region, the most effective option is mixed soybean + sorghum sowing.

Nowadays, people are suffering from food shortage. To meet the protein needs of people, meat and eggs of birds are of great importance. Among non-infectious diseases of quails in Azerbaijan, ovarian and oviduct pathologies are mainly observed. Ovarian pathologies are most often observed in ovaries of white English breed. Eggs obtained from them as a result of ovarian disease have no bark, are deformed, their weight is reduced, striped deposits are observed on the bark, and their ability to hatch is reduced. To prevent diseases of quails after 210 days use sodium salt of succinic acid, Aydagh zeolite, sprouted and enriched with ultraviolet rays wheat and Poly-Vital. Ovarian and oviduct diseases are prevented, and egg quality is improved.
Perifocal Edema in Gliomas. Pathogenesis, Clinical Picture, Treatment
Authors: Karimov Zh.
Published: August 2024

Surgical treatment of malignant glial tumor is a complex task due to the lack of clear boundaries and contours, its high invasiveness in healthy brain tissues and the formation of intense edema, due to low differentiation in color and consistency between tumor and brain tissue. The main symptomatology of glial tumors is due to peritumoral edema, which can lead to severe symptoms, including neurological dysfunction, dislocation of structures and brain hernia. The main task of neurologists, neurosurgeons and resuscitators in the pre- and postoperative periods is to reduce the aggressive mass effect of the perifocal edema zone in gliomas. In recent years, steroid therapy has been the standard treatment for perifocal edema in space-occupying lesions of the brain. In recent years, the study of the role of cerebral lymphatic vessels involved in the regulation of cerebrospinal fluid and the formation of cerebral edema has changed views on the treatment of perifocal edema in gliomas. The aim of this study was to study the pathogenesis, clinical features and treatment of peritumoral edema in gliomas. The known mechanisms causing peritumoral edema in glial tumors of the brain have been studied and summarized. A comparative analysis and discussion of the results of modern methods for treating perifocal cerebral edema in glial tumors have been carried out and prospects for future methods for treating cerebral edema are presented. Further studies of perifocal edema around a glial tumor of the brain are needed to improve the prognosis of the pre- and postoperative periods and increase the effectiveness of edema treatment.
