Socio-psychological problems of minors from single-parent families
Authors: Chala Tatiana
Published: October 2023

The article reveals the socio-psychological problems of minors from single-parent families. It has been shown that the most common type of socially dysfunctional family is a conflict family, that is, one where family members cannot or do not know how to solve emerging problems using constructive methods. Minors raised in such families, without a positive example, also build relationships with others accordingly. Such minors are characterized by a low level of social identity, a low level of socio-psychological adaptation and distorted value orientations. That is, minors from families at risk are characterized by an imbalance of socialization components.
The program for developing the socialization of at-risk minors must be aimed at developing the adolescent’s adaptive capabilities (developing the ability to understand people and social situations, a positive self-concept, reflexive skills); development of social competence (formation of adequate self-esteem, consistent with the level of aspirations; skills in mastering the emotional state, relieving emotional stress, managing means of communication, constructive interaction in various life situations); changing the value picture of the world. In parallel with classes for teenagers, classes should be held for parents aimed at developing the skills and abilities to help children develop skills that increase their level of socialization.
Key words: minors, single-parent families, dysfunctional families, addictive behavior, prevention, psychocorrection.
Personal reflection and responsibility in the conditions of continuous social changes
Authors: Kovalchuk Zoryana , Kolisnyk Roksolana , Toba Marianna , Tsarenok Lily , Kaskov Igor
Published: October 2023

The article reveals the peculiarities of personal reflection and responsibility in the conditions of constant social changes. It is shown that the evolution of socially significant knowledge involves a change in approaches to its reproduction, in particular, new content is extracted from previously existing, philosophically grounded social knowledge and meanings, which directly relates to the process of reflection and development of responsibility. Social psychology is currently stimulated by epistemology to carry out interdisciplinary analytical generalizations, which is also reflected in modern theoretical constructions. Consistency and integration of two spheres of knowledge - sensibility and rationality, are able to transform individual fragments of acquired knowledge into a system of world understanding, forming a synthetic perception that determines world understanding. At the same time, the imagination, capable of providing detailed knowledge about the subject, also builds a corridor of possibilities for the development of reflection and personal responsibility in the conditions of constant social changes.
Keywords: personal reflection, responsibility, social responsibility, social changes.

Published: October 2023

The article describes the means of personal health protection in the conditions of systemic changes in society. The process of forming health-preserving behavior includes assessment and self-assessment of the individual's health. Projects to support the state of health of the individual, aimed at prolonging the active creative period of life, should have a systemic nature. This involves not only the formation of appropriate social programs, the creation of appropriate conditions for the external environment and infrastructure (including information), but also the introduction of health-preserving technologies into the activities of economic organizations, increasing the importance of environmental culture, physical culture and sports in the educational, industrial, and everyday life of the population taking into account the complexity, integrated qualified influence of various subjects of socialization (sociologists, teachers, medical workers, psychologists, parents, managers of enterprises, institutions, power and administrative structures and the population in general).

Published: October 2023

The article reveals the problem of youth giftedness and the peculiarities of its development in the conditions of a problematic society. It is shown that the most intellectually gifted teenagers are the most tolerant, treat the people around them better, and have no emotional and communication problems. The problematic behavior of some gifted students should be considered as a reaction of unsatisfied ambition and psychological protection. Such a reaction occurs if the type of giftedness does not correspond (or does not fully correspond) to the profile of the subjects of advanced study or the general level of intelligence is insufficient for easy assimilation of complex educational programs, as well as in the case when the educational environment, the psychological climate of the class is such as to promote consolidation maladaptive behavior. It is emphasized that the process of socialization of gifted youth can be optimized thanks to the well-thought-out formation of class groups.

Authors: Яремчук Віталія
Published: October 2023

У статті здійснено емпіричне дослідження гендерних особливостей конфліктної поведінки неповнолітніх з неповних сімей. Визначено, що конфліктні суперечності представників різної статі виникають між їх традиційними та ситуативними ролями, які визначає суспільство.В емпіричному дослідженні було визначення взаємозв’язку гендерної ідентичності, пріоритетного стилю поведінки у конфлікті та акцентуацій характеру.За результатами дослідження виявлено, що 7% респондентів мають маскулінну гендерну ідентичність. 23% респондентів - фемінінну. Такі стратегії поведінки як компроміс, уникнення та пристосування – основні стилі поведінки фемінінних респондентів, які мають високу емотивну акцентуацію, та низьку акцентуацію збудливості. Андрогінну гендерну ідентичність мають 70%. респондентів. Більшість андрогінних респондентів, стилем поведінки у конфлікті обирають уникнення та компроміс, і зовсім не обирають суперництво. Тобто респонденти схильні до задоволення потреб опонента у конфлікті, або обох учасників конфліктної ситуації, досягають згоди на основі взаємних поступок, пропозицій варіантів вирішення ситуації, що знімає виникле протиріччя. Демонстративна, тривожна та дистимічна акцентуації у більшості андрогінних респондентів знаходяться на низькому рівні, а емотивна та циклотимна – на високому. Отже, такі особистості виокремлюються високою чутливістю, вразливістю, відзначаються глибиною переживань у галузі тонких емоцій, схильні до невмотивованих різких змін настрою протягом короткого часового інтервалу.Зазначено, що проблема впливу гендерних особливостей особистості на вибір стратегії поведінки в конфлікті у неповнолітніх з неповних сімей набуває зростаючого наукового інтересу до гендерного аспекту, як детермінанти поведінки особистості. Гендерний аспект, у сфері стратегії конфліктної поведінки, проявляється досить чітко. Гендерні особливості поведінки в конфлікті зумовлені особливостями гендерних ролей, а також іншими причинами.

Published: October 2023

This study was aimed to identify the present status of rice milling, map and analyze milled rice along with associated constraints and recommend priority areas of interventions using primary and secondary sources data during the period of 2012-14. In a quantitative survey, stratified random sampling was used to identify respondents, while qualitative investigations involved focus groups and key informant interviews. In the country, there are about 15,500 husking mills, 650 semi-automatic mills, and 300 automatic rice mills. Husking mills still dominate the rice milling sector and it covers about 70% of total milled rice production. However, recent trends show that the husking rice mills fail to compete with modern automatic and semi-automatic rice mills in terms of quality finished products and market demand, in turn shifting to semi-automatic and automatic rice mills is going on. The milling capacity and capacity utilization of husking mills was found to be 0.8-1.0 th-1 and 34%, respectively. Milling cost, profit per ton of fine parboiled rice and BCR for husking were found to be Tk. 2601, Tk. 3637 and 1.4, respectively. The profit margin for parboiled fine rice processed in a husking mill was found to be 37.04%. Employment opportunities in terms of labor and staff requirement for husking mills were found to be 14.17 man hours per metric ton of paddy and 6.95 man hours per tonne of paddy, respectively. Husking rice mills produce more broken, less head rice recovery and quality is less than automatic rice mills. Beside these, in husking mill bran and husk are mixed together that’s not suitable for edible oil extraction and briquette production. In terms of quality of rice e.g. less broken rice, absence of stones and black kernels, brightness, color etc., the rice mills having modern equipment produce higher quality rice, with higher market demand and higher profit making ability compared to rice mills having traditional equipment.

Authors: Badshah M A , Ibrahim M , Mei T N
Published: October 2023

To study the long term rice-rape cropping effect on weed seed bank size and composition, soil samples were collected from a long term (2004–2012) experiment under the cultivation techniques of conventional tillage transplanting (CTTP), no-tillage transplanting (NTTP), conventional tillage direct seeding (CTDS), and no-tillage direct seeding (NTDS) at a various soil depths of 0-5 cm, 5-10 cm, 10-15 cm, and 15-20 cm during 2011- 2012. Results indicated that, the highest weed seed accumulation of most species was in the 0-5 cm soil depth. More than 60% (% to total weed seeds) seeds were germinated at 20 days after placement of tray (DAP). The seed bank size of Echinochloa crus-galli(L) under direct seeded was 53% higher than transplanted in both years irrespective of tillage system. It decreased 67% under CT and 87% under NT from 0-5 to 5-10 cm soil depth in 2011. The ranked of weed species were grass > broad leaf > sedge based on their number per unit area in both years. The rank of Echinochloa crus-galli(L) was CTDS > NTTDS > NTTP > CTTP among the treatments at 0-5 cm soil depth in both years. Monochoria vaginalis (Burm.f) Kunth, Fimbristylis miliacea and C. iria L were fewer in number. The pressure of germination of weed seeds was more at 20  DAP at 0-5 cm soil depth. Total number (up to 60 DAP) of Echinochloa crus-galli  was higher in CTDS at 0-5 cm soil depth in both the years and drastically reduced under no tillage than under conventional tillage towards deeper horizon of soil.

Authors: Cripps Tony , Imai Takao , Toland Sean
Published: October 2023

This paper elucidates a research project that aims to understand and support the practical needs of pre-service English teachers who intend to teach at junior and senior high schools in Japan. Each day, novice English teachers who work in the Japanese public school system are facing challenges for which their pre-service training has failed to prepare them. Regrettably, the support structure for English teachers in the public system is sadly lacking. As part of this research project pre-service teachers of English (n=20) were asked through an online questionnaire to identify what topics they would like to be included in teacher-training workshops designed to address their needs. A series of one-day workshops were then developed based on these perceived needs. This paper explores the efficacy of the first two workshops based on the participants’ (n=28) informal and written feedback. The authors map out the design of future workshops and argue that practical support is essential considering the current teacher-training structure in Japan. This research project aims to provide realistic solutions to many of the common problems that Japanese teachers of English encounter in their professional practice. It is hoped that fellow educators will find this paper useful when considering making changes to their own educational contexts.
DESIGN OF WIRELESS EV BATTERY CHARGING SYSTEM USING SQUARECIRCULAR COUPLED COILS WITH DIFFERENT MISALIGNMENTS
Authors:   Malla Reddy College of Engineering and Technology, Bukya Ravi
Published: October 2023

Now a days, inductive power transfer (IPT) has gained a lot of attention from researchers as it has ease of use and realiability for electric vehicle (EV) battery charging systems. This paper examines the increasing attention from researchers towards inductive power transfer (IPT) as a means of charging electric vehicle (EV) batteries. This interest originates from the user-friendly characteristics and notable reliability associated with IPT. The evaluation of mutual inductance (MI) holds importance within the domain of Inductive Power Transfer (IPT) systems, as it serves a critical function in enabling effective power transfer. Therefore, it is essential to perform a comprehensive analysis of the mutual inductance between the two coils that are connected through inductive coupling. This study provides an examination of mutual inductance (MI) and efficiency within the context of interoperability conditions of interconnected coils. The transmitter coil is represented as a square structure, denoted as TxS, whereas the receiving coil is represented as a circular structure, denoted as RxC. Furthermore, the application of ferrite cores and steel chassis inclosures, in combination with coils, is utilised for the objective of electric vehicle (EV) battery charging. The magnetic induction (MI) analysis is performed by the utilisation of finite element method (FEM) simulation. The finite element method (FEM) simulation outcomes of the interconnected coils with misalignments, encompassing both non-core and steel chassis configurations, are juxtaposed with the corresponding empirical observations.

Published: October 2023

Toprak erozyonu, toprağın üst katmanının aşınarak başka bir yere taşınmasını ifade eden doğal bir süreçtir. Bu oluşum beşeri faaliyetlerin arazi örtüsünde değişimlere neden olmasıyla artan mekânsal bir probleme dönüşmüştür. Toprak erozyonundaki artış toprak verimliliğini olumsuz etkilediği gibi gıda güvenliğini de tehdit etmektedir. Toprak erozyonu kapsamındaki çalışmalar, sürecin işleyişini anlamak ve ortaya çıkan olumsuz etkileri en aza indirmek için sediman taşınımı ve erozyona duyarlı alanların belirlenmesi konularına yoğunlaşmıştır. Son 30 yılda bu konudaki modelleme uygulamalarının artması toprak erozyonu sorunu üzerine ilginin arttığını göstermektedir. Bu çalışmanın amacı toprak erozyonu konusunda en çok başvurulan modellerin geçirdiği değişimin literatür kapsamında değerlendirilmesidir. Bunun için modellerin veri özellikleri ve algoritma yapıları detaylı bir biçimde incelenmiş ve onlarca model arasında USLE/RUSLE, SWAT ve WEPP modelleri ile makine öğrenmesi yaklaşımlarının uygulama sayıları bakımından ön plana çıktığı belirlenmiştir. Bazı modellerin daha çok tercih edilme nedenlerinin farklı ortam koşullarına uyumlu olmaları ve ortamı yüksek doğrulukta benzetim yapabildiklerinden kaynaklandığı sonucuna varılmıştır.

An Analysis of the Vibration Characteristics of an Aviation Hydraulic Pipeline with a Clamp
Authors: Liu Yong , Wei Jinting , Du Hao , He Zhenpeng , Yan Fangchao
Published: October 2023

Taking an aviation hydraulic pipeline as the research object, a fluid–solid coupling vibration model of the pipeline system, considering the influence of the clamp, is established. The clamp is equivalent to the combined form of the constraint point and the pipeline. The equivalent stiffness of the clamp in each direction is obtained via the finite element method and substituted into the vibration model. The vibration response of the hydraulic pipeline system is obtained by changing the boundary conditions. The validity and accuracy of the vibration model were verified via the finite element method. The results show that the maximum error of the natural frequency of the pipeline system is within the acceptable range, which can prove that the model can better simulate the dynamic characteristics of the pipeline system and has a certain engineering reference value for the vibration analysis of hydraulic pipelines in aviation.
Bridging the Technology Gap: Strategies for Hybrid Rocket Engines
Authors: Glaser Christopher , Hijlkema Jouke , Anthoine Jérôme
Published: October 2023

Hybrid rocket propulsion, first demonstrated by the Russian GIRD-09 rocket in 1933, combines liquid oxidizer and solid fuel for thrust generation. Despite numerous advantages, such as enhanced safety, controllability, and potential environmental benefits, hybrid propulsion has yet to achieve its full potential in space applications. In recent years, the research on hybrid propulsion has gained enormous momentum in both academia and industry. Recent accomplishments such as the altitude record for student rockets (64 km), the launch of the first electric pump-fed hybrid rocket, and a successful 25 s hovering test highlight the potential of hybrid rockets. However, although the hybrid community is growing constantly, industrial utilizations and in-space validations do not yet exist. In this work, we reassess the possibilities of hybrid rocket engines by presenting potential fields of applications from the literature. Most importantly, we identify the technical challenges that hinder the breakthrough of hybrid propulsion in the space sector and evaluate the technologies and approaches necessary to bridge the gaps in hybrid rocket development.
The Aerodynamic Performance of a Novel Overlapping Octocopter Considering Horizontal Wind
Authors: Lei Yao , Wang Jie , Li Yazhou
Published: October 2023

This paper investigates the aerodynamic performance of an overlapping octocopter with the effect of horizontal wind ranging from 0 to 4 m/s using both low-speed wind tunnel tests and numerical simulations. The hovering efficiency and the potential control strategies of the octocopter under the effect of horizontal wind are also validated using blade element momentum theory. The velocity distribution, rotor pressure and vortex of the downwash flow with the horizontal wind are presented using the Computational Fluid Dynamics (CFD) method. Finally, wind tunnel tests were performed to obtain the thrust and power consumption with the rotor speed ranging from 1500 to 2200 rpm for horizontal winds at 0 m/s, 2.5 m/s and 4 m/s. The results showed that horizontal wind decreased the flight efficiency of the planar octocopter and had little effect on the coaxial octocopter. It is also interesting to note that horizontal wind is beneficial for thrust increments at a higher rotor speed and power decrements at a lower rotor speed for the overlapping octocopter. Specifically, the horizontal wind of 2.5 m/s for a lower rpm is presented with a power decrement with proper aerodynamic interference between the rotor blades. Additionally, the overlapping octocopter obtains a higher hover efficiency at 4 m/s compared to traditional octocopters, which is more suitable for flying in a cross wind with a more compact structure.
Physiological and Agronomic Characteristics of Alternative Black Barley Genotypes (Hordeum vulgare var. nigricans and H. v. var. rimpaui) under Different Hydrothermal Conditions of the Growing Seasons
Authors: Szczepanek Małgorzata , Nowak Rafał , Błaszczyk Karolina
Published: October 2023

Black-seeded barley can be a valuable raw material for functional food. However, its restoration to cropping should be preceded by the identification of the characteristics determining productivity. The field study was conducted to identify specific parameters of the black-seeded barley genotypes (Hordeum vulgare var. nigricans and H. v. var. rimpaui) and compare them with common barley (H. vulgare) under the different hydrothermal conditions of the two growing seasons of 2021 and 2022. Our research has shown that each genotype has a set of specific characteristics that best describe it at a given developmental stage. H. v. rimpaui was well characterized by chlorophyll fluorescence parameters such as FV/FM, FV/F0, and PIABS at the seedling stage and H. v. nigricans by FV/FM and FV/F0 at the flag leaf stage. Moreover, H. v. var. rimpaui was distinguished by a high biomass of shoot (726 g m−2) and straw yield (5.04 t ha−1) but H. v. var. nigricans by a high number of sterile generative tillers (103 m−2 in the dry year 2022). Further research should focus on the response of black-seeded barley genotypes to abiotic stresses, while in agronomic practice, efforts should be made to increase the number of grains per ear and 1000-grain weight.

Understanding the spatial–temporal variability of soil enzymatic activity and its relationship with nitrogen (N) resources in the soil and crop yield is crucial in rational management practices of mineral fertilization. The scarcity of comprehensive studies on geostatic analyses of agricultural soils and plant yields, which would take into account both temporal and spatial variability, was the reason for undertaking this research. The aim of this study was to determine the spatial and temporal variability of the activity of soil enzymes, such as acid (PAC) and alkaline (PAL) phosphatases, urease (URE) and protease (PROT), the content of N-NH4 (ammonium ions), N-NO3 (nitrate ions), phosphorus (P), pH, moisture, as well as crop yield on a conventionally managed farmland of 40 ha. During the two-year experiment, soil samples were collected from 37 measurement points. Wheat was the first tested crop, followed by oilseed rape. It was shown that all the tested soil parameters showed temporal and spatial variability, and a significant number of them were significantly higher in July. The creation of raster maps showing the distribution of the tested parameters allowed for the observation of the considerable activity of PAC, PAL, URE, and PROT, as well as a high application of N-NO3 in the southern part of the field during the growth of the plants. The statistical analysis revealed a negative interaction between the N-NH4 and N-NO3 and the urease in the soil under the cultivation of plants. The pH and the percentage of moisture in the soil also had higher values in the south of the field. This pointed to the existence of separate production zones in the south-central part of the field, characterized by a higher yield of wheat and rape. On the basis of the conducted research, it was unequivocally stated that the values of enzymatic and chemical parameters of the soil were reflected in the size of the yield obtained, which allows conclusions to be drawn with respect to the rational management of N in the production process, laying the foundations for precision agriculture.

Nowadays, agriculture must satisfy the growing demand for food, and increasing its sustainability, from an environmental, economic, and social point of view, is the only way to achieve this. The objective of this study was to increase the water and nutrient use efficiency of a melon crop during two consecutive seasons under commercial conditions, growing under semi-arid area. For this purpose, two treatments were studied: (i) a farmer treatment (FRM), fertigated at ~100% of crop evapotranspiration (ETc) during the whole growing season; and (ii) a precision irrigation treatment (PI), irrigated by adjusting, between flowering and ripening, the weekly farmer irrigation to minimize the leaching below the root system. The threshold for allowable soil water depletion in the active root uptake zone was set at 20–30%. The cumulative water savings in each year relative to the FRM treatment ranged between 30 and 27% for 2020 and 2021, respectively. Yield was not negatively affected, with no differences in fruit load (fruit per m) or fruit weight (kg) between irrigation treatments, although higher yields were obtained in the second year due to seasonal changes. The crop water status indicators evaluated (stem water potential, net photosynthesis, and stomatal conductance) were not affected by the irrigation treatments. Water and nitrogen productivity, on average, increased by 45.5 and 54.4% during the experimental period, respectively; the average PI ascorbic acid content increased by 33.4%.

Dominant species play a principal role in controlling and maintaining ecosystem stability. Stipa breviflora is the dominant species in desert steppe. Changes in the stability of a plant population will further affect the stability of the broader habitat, such as the desert steppe. In the desert steppe ecosystem, it is not clear what level of grazing intensity is best for improving the grazing tolerance and stability of the vegetation. And, the study of this question should involve a multi-dimensional, comprehensive analysis. This study will utilize variance analysis, plant population stability, and trade-off index to study S. breviflora, the dominant species in the desert steppe in Inner Mongolia, and its performance under four grazing intensities (control, CK, 0 sheep·ha−1·half year−1; light grazing, LG, 0.93 sheep·ha−1·half year−1; moderate grazing, MG, 1.82 sheep·ha−1·half year−1; and heavy grazing, HG, 2.71 sheep·ha−1·half year−1) over six scales (5 cm × 5 cm; 10 cm × 10 cm; 20 cm × 20 cm; 25 cm × 25 cm; 50 cm × 50 cm; and 100 cm × 100 cm). The characteristics of the population stability of S. breviflora were explored. The results showed that the response of S. breviflora’s stability to heavy grazing was multidimensional. Heavy grazing reduced the population stability of S. breviflora. Across different dimensions, base coverage was the first of the population stability metrics of S. breviflora to destabilize, followed by projection coverage, density, and height. Heavy grazing also affected the trade-offs of S. breviflora’s population stability across different dimensions. In general, the trade-off degree decreased as the grazing intensity increased, and it increased as the scale increased.

Peripheral neuropathy is an important adverse effect caused by some chemotherapeutic agents, including oxaliplatin (OXA). OXA-induced peripheral neuropathy (OIPN) is a challenging condition due to diagnostic complexities and a lack of effective treatment. In this study, we investigated the antiallodynic effect of β-caryophyllene (BCP), a cannabinoid type 2 (CB2) receptor agonist, in a mouse model of OIPN. BCP treatment inhibited OXA-induced mechanical and cold allodynia in both preventive and therapeutic drug treatment regimens. Experiments with the CB2 receptor agonist GW405833 confirmed the role of CB2 receptors in OIPN. The CB2 antagonist SR144528 abrogated the anti-nociceptive effect of BCP on mechanical allodynia, without impacting OXA-induced sensitivity to cold. BCP decreased neuroinflammation, as inferred from TNF, IL-1β, IL-6, and IL-10 profiling, and also reduced ROS production, lipid peroxidation, and 4-hydroxynonenal protein adduct formation in the spinal cords of OXA-treated mice. BCP did not affect the antitumor response to OXA or its impact on blood cell counts, implying that the cytotoxicity of OXA was preserved. These results underscore BCP as a candidate drug for OIPN treatment via CB2 receptor-dependent mechanisms, and anti-inflammatory and antioxidant responses in the spinal cord.

Published: October 2023

Pest control is essential for increasing agricultural production. Agricultural drones with spraying systems for pest control have generated great interest among farmers. However, spraying systems installed on unmanned aerial vehicles, like any other sprayer, can cause damage to the environment due to drift of the agent. Air induction (AI) nozzles are known to produce less drift (e.g., larger spray drops) than other nozzles, but there is a lack of research analyzing their effectiveness in combination with drones. In this study, AI and flat fan nozzles were installed on drones to evaluate their spray and pest control performance. Aerial spraying was conducted on rice and soybeans to measure the coverage and penetration ratio and analyze the crop production as well as the crop damage due to pests and diseases. The drone flight was conducted at an altitude of 3 m and a velocity of 2 m/s. Spray droplets were collected using water-sensitive paper at two heights above the soil surface. The experiments showed that the crop coverage with the AI nozzle was 130% higher than that with the flat fan nozzle. The drift reduction of AI nozzles increased the coverage of spray droplets. But the difference in the penetration ratios, which is the ratio of agents to be delivered inside the crop, was not significant between the nozzles. Also, there was no significant difference in crop yield and pest control efficacy. Consequently, the performance of the AI nozzle did not show differences from that of the XR nozzle, except for coverage. However, the AI nozzle raised less drift, so it should be considered for use in aerial control.

The topic of battery state-of-health monitoring via electrical and non-electrical testing procedures has become of increased interest for scientific researchers, due to the imposed goal of expanded industrial sustainability. Within the present study, we propose a novel approach for monitoring the temperature of batteries by means of infrared thermography. In order to improve the accuracy of the performed measurements and to overcome the limitations imposed by the cylindrical housing of the batteries, we have developed a unique method for monitoring and capturing the temperature of the battery over the entire housing. An experimental system was built, through which the battery performs a rotational movement relative to its axis, with this rotation motion being synchronized with the frame rate of the thermal camera. The resulting thermographic images are processed using specifically developed software. This software enables the segmentation of certain sections of the battery’s surface from a defined spatial perspective. These selected segments are subsequently utilized to generate a three-dimensional representation of the battery’s surface temperature’s distribution. In this way, errors in the obtained results which are caused by the viewing angle are avoided. Additionally, we developed and presented a method for the increasing of the resolution of captured thermograms.

Ion channels play a crucial role in a wide range of biological processes, including cell cycle regulation and cancer progression. In particular, the transient receptor potential (TRP) family of channels has emerged as a promising therapeutic target due to its involvement in several stages of cancer development and dissemination. TRP channels are expressed in a large variety of cells and tissues, and by increasing cation intracellular concentration, they monitor mechanical, thermal, and chemical stimuli under physiological and pathological conditions. Some members of the TRP superfamily, namely vanilloid (TRPV), canonical (TRPC), melastatin (TRPM), and ankyrin (TRPA), have been investigated in different types of cancer, including breast, prostate, lung, and colorectal cancer. TRP channels are involved in processes such as cell proliferation, migration, invasion, angiogenesis, and drug resistance, all related to cancer progression. Some TRP channels have been mechanistically associated with the signaling of cancer pain. Understanding the cellular and molecular mechanisms by which TRP channels influence cancer provides new opportunities for the development of targeted therapeutic strategies. Selective inhibitors of TRP channels are under initial scrutiny in experimental animals as potential anti-cancer agents. In-depth knowledge of these channels and their regulatory mechanisms may lead to new therapeutic strategies for cancer treatment, providing new perspectives for the development of effective targeted therapies.

Published: October 2023

Background: Knee osteoarthritis (KOA) is one of the most common causes of disability in elderly patients and tends to be a major burden on social and health care spending. Despite its severe socioeconomic impact, KOA remains, to date, an incurable disease. Due to its proper characteristics, KOA represents a favorable disease model for experimenting with senotherapeutics, a group of treatments that counteract the development of age-related disorders and chronic diseases. In recent years, the use of intra-articular hyaluronic acid (IAHA) in the treatment of diseases related to the wear and tear of the articular cartilage has been gaining popularity. Given its ability in joint lubrification, shock absorption, and cell signaling, our aim is to investigate, through the existing scientific literature, its potential role as a senomorphic agent, emphasizing its crucial function in KOA patients. Indeed, senomorphics are a particular group of senotherapeutics capable of modulating the functions and morphology of senescent cells to those of young cells or delaying the progression of young cells to senescent cells in tissues. Methods: A search in the scientific literature (PubMed, Cochrane Library, and Google Scholar) was carried out from 2019 to 2023, thus the last 5 years. Results: One hundred thirty-eight articles were found concerning the role of hyaluronic acid injections in KOA patients. In these studies, its therapeutic efficacy, its anti-inflammatory properties, and its low risk of side effects emerged. Conclusion: IAHA injections are a valuable treatment option for KOA while they can provide pain relief, improve joint function, and slow the progression of joint degeneration. The inhibitory effect of HA on MMP13 and its action as a senomorphic agent suggests that it may have additional benefits beyond its lubricating and shock-absorbing properties. In order to clarify its mechanisms of action and to optimize its clinical use, further studies are definitely needed.
