Преодоление трудных жизненных ситуаций у алкозависимых мужчин и женщин: возможности психокоррекционных групповых занятий
Authors: Кузенко Светлана С. , Бордоносенко Анастасия С.
Published: January 2025

Introduction. The article is devoted to the analysis of strategies for overcoming difficult life situations of men and women with alcohol addiction. Due to the current need to revise the concepts of rehabilitation measures and psychological impact on persons belonging to the addictive category of the population, we have developed and implemented a program of group sessions with patients and evaluated its effectiveness.
Methods. The study was conducted among 120 respondents in the Lugansk Republican Narcological Dispensary: 60 patients with I-II stages of chronic alcohol addiction (30 men and 30 women), as well as 60 employees of the medical institution without alcoholism in the anamnesis (30 men and 30 women). The method of psychological testing and psychodiagnostic tools were used: Test "Overcoming Difficult Life Situations"; "Coping Behavior Questionnaire"; "Stress Susceptibility Questionnaire"; "Level of Subjective Control Questionnaire"; Michigan Alcohol Screening Test. The group psychocorrectional sessions were aimed at increasing the level of expression of adaptive strategies for overcoming difficult life situations in men and women with alcohol addiction, along with the reduction of dysfunctional and maladaptive behavioral strategies; increasing the level of internality of the locus of personality control, as well as reducing the severity of stress and actualization of resources for its overcoming.
Results. Addictive men prefer to engage in confrontation with others with a clear sense of self-pity. Women are oriented towards obtaining effective and emotional support and delegating personal responsibility. Psychocorrectional group sessions contribute to the manifestation of active and goal-oriented strategies of effective resolution of difficulties. The increase of self-control, acceptance of responsibility, as well as the decrease in susceptibility to stress with the increase in internality of the personality are resources for the formation of constructive behavior of alcohol-addicted patients.
Discussion. The externality of the addicts control locus and low stress resistance indicate a variant of the destructive manifestation of personal resources. The formation of a cognitive and practical basis for functional strategies is possible through a comprehensive rehabilitation process.

Published: January 2025

Introduction. The article explores the characteristics of adolescent deviant behavior in online communities. This study is the first to examine the specific role dispositions of adolescents prone to online deviance. We analyzed the mechanisms through which real-world personalities transform in the digital environment, leading to the development of both normative and deviant digital identities. Our research focus was on teenagers, as they represent the most vulnerable group, with their value systems undergoing reformation in the real world while their new social experiences are shaped online.
Methods. In the study, which involved a survey of 158 adolescents in both real and virtual spaces, the following methodologies were used: "Propensity for bullying in the Internet space" (Luchinkina, 2019); individual personality orientation diagnostic methodology (modified by N.P. Fetiskin); locus of role conflict diagnostic methodology by P. P. Gornostai. 
Results. Adolescents with an egoistic orientation are more prone to engage in online deviant behaviors such as harassment. Conversely, adolescents with a cooperative orientation are less likely to exhibit deviant behaviors, including verbal insults, harassment, disclosure of personal information, threats of physical violence, and social isolation. The desire for new online experiences, combined with a reduced interest in real-life interactions, contributes to both socially acceptable and deviant online roles. In contrast, adolescents with a marginalized orientation are more likely to engage in deviant behaviors such as harassment, insults, using fake names and profiles, social isolation, disclosing personal information, and making threats of violence. Furthermore, a correlation has been established between the locus of role conflict and specific forms of online deviant behavior.
Discussion. Cultural factors play a significant role in shaping individual online behavior patterns, influencing attitudes, values, and behavioral responses. Online activity can range from normative to deviant, with each influencing cognitive processes and online behavior.
The Impact of Mercury from Dental Amalgams on Pregnancy and
Childhood: A Health and Risk Assessment Evaluation
Authors: Escalante Erwin , Semenova Yuliya , Peana Massimiliano , Bjørklund Geir
Published: January 2025

Mercury is a pervasive global pollutant, with primary anthropogenic sources
including mining, industrial processes, and mercury-containing products such as dental
amalgams. These sources release mercury into the environment, where it accumulates in
ecosystems and enters the food chain, notably through bioamplification in marine life,
posing a risk to human health. Dental amalgams, widely used for over a century, serve
as a significant endogenous source of inorganic mercury. Studies have demonstrated
that mercury vapor can be released from amalgams at room temperature due to material
corrosion, potentially leading to chronic exposure. Pregnant women and children are particularly susceptible to mercury’s toxic effects, with research linking prenatal mercury
exposure to developmental delays, neurocognitive deficits, and conditions such as
autism spectrum disorder. Moreover, the long-term accumulation of mercury in the body
raises concerns about delayed health impacts in individuals exposed during childhood.
Recent findings suggest even low levels of mercury exposure may contribute to kidney
damage mediated by oxidative stress, highlighting the importance of monitoring mercury levels in vulnerable populations. Prenatal mercury transfer and postnatal exposure
through breastfeeding further amplify the risks. This review critically assesses the health
implications of mercury exposure from dental amalgams, focusing on its impact on pregnancy and childhood development. It underscores the need for updated regulatory measures to mitigate mercury-related risks and calls for further research to clarify the extent
of mercury’s long-term effects on human health.

Authors: Prema S. , Verma Rakesh , Nagarwal Amritesh , Bharkatiya Meenakshi , Baghel Madhuri , Kishore Ladli , Wal Pranay , Gasmi Amin
Published: January 2025

Objective:

The usage of doxorubicin (DOX), an antineoplastic drug that is frequently
used for the cure of cancer, is restricted to maximal doses due to its cardiac toxicity. Reactive
oxygen species produced by DOX result in lipid peroxidation and organ failure, ultimately
resulting in cardiomyopathy. Due to its high polyphenol content, virgin rice bran oil (VRBO) is
a diet nutritional supplement with a strong antioxidant. This study aimed to assess the potential
defense of VRBO against DOX-induced cardiotoxicity.

Methods:

VRBO and DOX injections were administered to thirty male Wistar rats for 42 days
after being randomly assigned to five groups.

Results:

The study demonstrated the cardioprotective effects of VRBO against doxorubicin
(DOX)-induced cardiotoxicity. VRBO (0.71 and 1.42 ml/kg) significantly improved the heart-tobody weight ratio, reduced elevated serum CK-MB and LDH levels by 18.4% and 52.7%, respectively, and increased HDL by 43.1%. ECG parameters also improved, with reductions in QT
interval (19%), ST interval (28%), and QRS complex (15%). VRBO enhanced systolic blood
pressure (up to 21%) and heart rate (7.1%). Antioxidant markers showed notable recovery, with
MDA levels reduced by 66.1%, while GSH, SOD, and catalase levels increased by 129.4%,
158.2%, and 84.8%, respectively.

Conclusion:

A cardioprotective benefit was found at middle and higher VRBO dosages. In order
to demonstrate the effectiveness of VRBO as a cardioprotective medication, further research on
dosage response and bioavailability is required.

Published: January 2025

Background:

KEPs (kidney exchange programs) facilitate living donor kidney transplantations (LDKT) for patients with incompatible donors, who are typically higher risk than non-KEP patients because of higher sensitization and longer dialysis vintage. We conducted a comparative analysis of graft outcomes and risk factors for both KEP and non-KEP living donor kidney transplants.

Methods:

All LDKTs performed in the Netherlands between 2004-2021 were included. The primary outcome measures were one-, five- and 10-year death censored graft survival (DCGS). The secondary outcome measures were delayed graft function (DGF), graft function, rejection rates and patient survival. We used a propensity score matching model to account for differences at baseline.

Results:

Out of 7536 LDKTs, 694 (9%) were transplanted via the KEP. Ten-year graft survival was similar for KEP 0.916 (95% CI: 0.894 - 0.939) and non-KEP 0.919 (0.912 - 0.926, p = 0.82). We observed significant differences in five-year rejection (12% vs 7%), and five-year patient survival (KEP: 84%, non-KEP: 90%), which was non-significant after propensity score matching. Significant risk factors for lower graft survival included high donor age, re-transplantations, extended dialysis vintage, higher panel reactive antibodies, and nephrotic syndrome as the cause of end-stage kidney disease .

Conclusions:

Transplantation via KEP offers a viable alternative for patients lacking compatible donors, avoiding specific and invasive pre- and post-transplant treatments. KEP's similar survival rate to non-KEP suggests prioritizing KEP LDKT over deceased donor kidney transplantation, desensitization, and dialysis. However, clinicians should consider the identified risk factors when planning and managing pre- and post-transplant care to enhance patient outcomes. Thus, we advocate for the broad adoption of KEP and establishment in regions lacking such programs, alongside initiation and expansion of international collaborations.
Interweaving Story and Theory
Authors: Baldrian Sona
Published: January 2025

Based on organizational autoethnography, this article provides a personal account of how the women’s movement in Armenia has navigated the influx of democratization aid following the 2018 regime change. It examines how the overflow of development aid has transmuted the relationship between women’s rights NGOs and the Armenian state, leading to the further bureaucratization, professionalization, and institutionalization of the women’s movement. Drawing on the author’s personal experiences within the NGOized movement, the article explores the specific ways in which the political economy of gender aid has facilitated anti-feminist and anti-class struggle agendas, showing how close collaboration with the state and donor organizations has shrunk spaces for feminist organizing, impeding critical knowledge production and public mobilization efforts. It also examines the anti-gender dynamics within the local movement, highlighting how the concept of gender has been stripped of its revolutionary essence and operationalized for grants in essentialist and rather conservative terms. The article concludes by advocating for a critical reassessment of the NGO form, arguing for the need to explore alternative forms of feminist organizing that resist and move beyond the limits posed by NGOization.

Spring water and CO2 interaction at Popocatépetl volcano, Mexico
Authors: Martin-Del Pozzo A. L. , Inguaggiato S. , Aceves F. , Sáenz H. , Aguayo A.
Published: January 2025

Se presentan los resultados del monitoreo de HCO - y pH en manantiales del volcán Popocatépetl durante seis años del actual periodo eruptivo. Los pequeños picos en HCO - y P en manantiales se asocian a ascensos de pulsos pequeños de magma en el Popocatépetl. El magma proporciona fluidos ricos en CO2 al sistema hidrológico que es controlado por recarga meteórica. La PCO2 en equilibrio con los manantiales es de 2 a 4 órdenes de magnitud mayor al de agua saturada con aire. La alta presión de CO2 también sugiere una interacción directa con los fluidos magmáticos. Los isótopos de carbono apoyan un origen principalmente magmático para el CO2 disuelto.
A Review on: DDoS Detection in Cloud-Based Website Hosting Using Covariance Matrix Approach
Authors: Saxena Anjali , Datta Unmukh
Published: January 2025

Abstract: Particularly in cloud and IoT systems, this work investigates how the covariance matrix might improve Distributed
Denial of Service (DDoS) detection in challenging network situations. Still a constant difficulty, DDoS attacks take advantage of
the linked character of contemporary networks. Improving detection accuracy, reducing false positives, and allowing real-time
harmful traffic identification is the aim. The suggested approach analyses interactions between several network traffic
characteristics using the covariance matrix, therefore spotting abnormalities suggestive of DDoS activity. This method captures
subtle, multi-dimensional patterns usually missed by volume-based or signature-based techniques, therefore transcending
conventional approaches. In cloud and IoT environments, comprehensive datasets encompassing both valid & hostile traffic
assist the models to be trained. Dynamic adaptation to shifting assault pathways and advanced machine learning methods serve
to enhance the detection process. Comparative analysis reveals that by basically achieving superior accuracy and resilience, the
covariance matrix-based approach overcomes low-rate and zero-day threats. Strong network security is thus guaranteed even in
multi-tenant, high-traffic environments since the results demonstrate a clear decrease in false positives and improved detection
rates. This work offers a foundation for sophisticated, customizable anomaly detection techniques, therefore offering a possible
way to guard critical infrastructure from sophisticated DDoS attacks.

Authors: G Bukar A. , M Shettima , M Kunduri A. , H Sambo G.
Published: January 2025

Abstract: The ever-increasing traffic flow has become one of the most critical challenges faced by municipalities and
governments worldwide. This paper intends to ascertain the traffic flow parameters using geospatial technology for effective
traffic management around the Central Business District (CBD) in Maiduguri to provide solutions to the menace of traffic
congestion. Data were obtained from primary and secondary sources. The primary data were obtained from Unmanned Aerial
Vehicles (UAV) and Global Positioning System (GPS). UAVs were utilized to record (videography) the traffic flow of the chosen
traffic corridors during the peak hours (morning, 7:00 to 9:00 am and evening, 4:00 to 6:00 pm). The classification of the
vehicles and conversion to a common standard format was done in Microsoft Excel before being carried forward for GIS
Operations in ArcGIS 10.7 Environment to achieve geospatial spatial analysis and mapping of the field data. The results show
that Tricycles dominated the traffic during the peak periods, followed by Cars. This indicates that the Tricycle has been the
overriding and preferred means of public transport in Maiduguri since 2009 after the ban placed on motorcycles. The also
reveals that no matter the direction of movement in all the approach arms, Tricycles override all other means of transportation.
The results also show that all the Trio Intersections were observed to have high traffic volume on all their trajectory arms, with
only the Tabacco intersection having medium traffic volume during the morning peak period. Given the above findings, the
study recommended that the Government to consider the construction of a flyover, particularly at the post office intersection.
Theoretical Analysis of Specific Impulse at Lower Geo-Potential Altitude Range for a Paraffin-Fueled Hybrid Rocket Motor
Authors: Kambrath Sreehari , Thuluvath Jishnu
Published: January 2025

Abstract: This paper presents a theoretical performance of paraffin-based hybrid rocket motors, focusing on the ideal specific
impulse performance (Isp) at lower geo-potential atmospheric altitudes. The study considers n-docosane (C22H46) as fuel with
oxidizer as nitrous oxide (NO). Simplified mathematical modelling is employed to perform the analysis. The input
thermodynamic parameters are calculated for exhaust gas mixture under balanced stoichiometric chemical reaction based on
fixing a standardized exhaust temperature of 1000oK in relevance with material considerations. The analysis underscores the
influence of specific heat capacity and specific heat ratio on thrust coefficients. The nozzle area ratio is fixed as 2.5 and
accordingly the design exit Mach number (Me) is calculated using Chebyshev iterative method by formulating a transcendental
non-linear function and accordingly theoretical computations are performed based on the methodology followed. The inference
reveals that the ideal specific impulse ranges from 218 to 246 seconds across lower atmospheric geo-potential altitudes. This also
highlights the influence of chamber pressure on altitude as a performance assessment for propulsion system. The findings are
theoretical and delivers valuable insight into application of hybrid propulsion systems for altitude operations in future.

Introduction: Yellow fever is an arbovirus with two transmission cycles: sylvatic and urban. In Brazil, this is considered a notifiable disease, and communication is mandatory and immediate through the Disease Notification and Notification System. Objective: To analyze the epidemiological variables and completeness of yellow fever notification forms in the state of Mato Grosso do Sul. Method: This is a descriptive study with data from yellow fever notifications from the Disease and Notification Information System of Mato Grosso do Sul, from 2007 to 2022. Results: A total of 102 notifications of suspected cases were made, with the years with the highest rates of occurrence of notifications, respectively: 2008 (n = 30), 2017 (n = 15), 2018 (n = 15), and 2022 (n = 10). Two cases of yellow fever were confirmed, one in 2008 and another in 2010. Most notifications for suspected and confirmed cases were represented by males. Regarding the completeness of the “occupation” data, none of the municipalities reached completion above 90%; in the variable “signs and symptoms”, only 13 municipalities reached completion above 90%; and in relation to the “epidemiological antecedents”, only four municipalities had more than 90% completion. It should be noted that most of the information regarding suspected and confirmed cases was not filled in. Conclusions: The notification system is incomplete and has little information on suspected and confirmed cases of the disease, that is, it does not reflect the real occurrence and magnitude of this public health problem in the state.

Los corresponsales extranjeros en Madrid durante la Guerra Civil: dinámicas e identidades
Authors: Barreiro Gordillo Cristina
Published: January 2025

El comienzo de la Guerra Civil atrajo el interés mediático internacional. En un momento de fuertes tensiones entre fascismo y comunismo, muchos vieron el inicio del conflicto español como un campo de experimentación para un enfrentamiento de dimensiones mayores. Por este motivo, los principales medios internacionales enviaron a Madrid sus corresponsales más renombrados. Hemingway, Herbert, Matthews, Sefton Delmer, John Dos Passos o Mijail Kolstov fueron algunos de los corresponsales que estuvieron en España en este periodo. También encontramos corresponsales latinoamericanos en el conflicto como Binns o Cano Reyes y figuras femeninas como la mexicano-estadounidense Anita Brenner, que escribió numerosas crónicas desde España para Estados Unidos. En este artículo se pretende trazar un recorrido por la dinámica de trabajo que siguieron los corresponsales que estuvieron en Madrid desde julio de 1936  hasta abril de 1939. De este modo, se trata de comprender cómo las informaciones que salieron de la capital pasaron el filtro de censura y terminaron estableciendo unos parámetros mediatizados de la realidad española.
La frontera interior y el despliegue del Estado en el siglo XIX colombiano: dos documentos para la historia de Santa Rosa de Cabal
Authors: Nueva Ciencia
Published: January 2025

Los textos que transcribimos en esta ocasión para la sección Anales son el testimonio del proceso en el que se encontraba el territorio de la actual Colombia en durante la segunda mitad del siglo XIX. Hacia la década de 1840, una vez superada “la Guerra de los Caudillos Supremos”,  la república de la Nueva Granada debía enfrentar su consolidación como Estado-nación, lo que requería no solo la organización política de su territorio, sino también su integración y expansión hacia áreas menos controladas. En este marco, el territorio del Cauca jugó un papel central al proponerse como punto estratégico para la creación de nuevos asentamientos en su frontera norte, un espacio en transformación que conectaba con la histórica región de Antioquia. Este proceso no solo respondía a la necesidad de consolidar las fronteras internas, sino también de controlar territorios en disputa poco integrados al control estatal y a instituciones de poder que en muchos casos se habían establecido desde el temprano periodo monárquico.

W związku zachodzącymi zmianami na wsi rolnicy stają przed koniecznością dywersyfikacji swojej działalności. Jednym z rozwiązań może być założenie gospodarstwa opiekuńczego. Celem artykułu jest wskazanie korzyści i barier funkcjonowania gospodarstw opiekuńczych w Polsce. Na podstawie literatury przedmiotu, wywiadów eksperckich i zebranych wypowiedzi uczestników projektu „Samodzielnie (nie samemu) – wspieranie osób z niepełnosprawnością w powiecie tucholskim”, zebrano czynniki prorozwojowe oraz bariery funkcjonowania gospodarstw opiekuńczych z punktu widzenia ich uczestników oraz właścicieli. Czynniki zostały pogrupowane w kategorie: ekonomiczne, społeczne, zdrowotne i prawne. Pomiędzy uczestnikami a właścicielami wystąpiły różnice w zakresie postrzegania korzyści i barier w zakresie funkcjonowania tego typu placówek. Właściciele wskazują przede wszystkim korzyści ekonomiczne i społeczne, uczestnicy – społeczne i zdrowotne. Niepokojący jest fakt, że obie grupy wskazują oznaczają czynniki prawne jako bariery rozwoju gospodarstw opiekuńczych. W związku z tym rekomenduje się konieczność wypracowania konkretnych przepisów prawnych, wskazania miejsca gospodarstw opiekuńczych w systemie opieki społecznej. Ponadto winno się przygotować nowe, długoterminowe projekty uwzgledniające potrzeby beneficjentów bezpośrednich, a także ich opiekunów (np. wydłużenie czasu dobowej opieki ponad 8 godzin mogłoby umożliwić ich aktywizację zawodową).
Assessment of Social Welfare Progress of NEAZDP Beneficiaries in Yobe State of Nigeria
Authors: Sadiq Mohammed , Grema Isiyaku
Published: January 2025

Despite the implementation of the NEAZDP (North East Arid Zone Development Programme), the extent to which the program has improved the social welfare of its beneficiaries in Yobe State remains unclear, particularly in addressing income inequality, food security, and long-term socio-economic stability. Consequently, this study makes an attempt at assessing the social welfare progress of NEAZDP beneficiaries in Nigeria’s Yobe State. Further, the study used undated household survey data of the year 2023, collected with the aid of a well-structured questionnaire coupled with an interview schedule from a total of 396 households (120 beneficiaries, and 138 each for the spillover and control groups). The households were selected through a multi-stage sampling technique and the collected data were subjected to inferential statistical analysis. Empirically, the NEAZDP had a notable impact on socio-economic development, income inequality, and social welfare among its beneficiaries. The program improved beneficiaries’ socio-economic conditions, particularly in the areas of food security, asset acquisition, and wealth, while also reducing income inequality. However, the spillover group experienced even lower inequality, indicating strong indirect benefits. The analysis also revealed significant improvements in social welfare, particularly at the per capita income level, though food inflation negatively impacted both the beneficiaries and non-beneficiaries, exacerbating inequality. The findings suggest that while NEAZDP interventions effectively enhance economic stability and well-being, future strategies should focus on addressing internal disparities, mitigating inflationary pressures, and fostering long-term resilience in rural communities to sustain and deepen the program’s positive outcomes.
Design of thinned smart antenna of semi-circular dipole array for 5G massive MIMO system
Authors: Khan Anindita , Roy Jibendu
Published: January 2025

In a multi-user environment, wireless networks should be massive MIMO (MMIMO)
systems consisting of multiple antennas. MMIMO installs antenna arrays at
base stations and uses hundreds of transceivers and other RF modules to form
a very narrow and focused beam, thus reducing interference. The disadvantage
of MMIMO systems is large power consumption, and the RF module beamforming
network for multiple antennas is significant in terms of power consumption.
This paper presents a new low power beamforming technique for MMIMO systems.
The proposed semicircular array thinned smart antenna (TSA) can form a
secure beam for user terminals while reducing interference. In a thinned
array, selected antennas are kept off, which reduces power consumption but
the array pattern remains the same as the built-in array, and the sidelobe
level (SLL) is reduced. The thinned array antennas are designed at 5 GHz of
the sub-6GHz band. The differential evolution (DE) algorithm is utilized to
determine the optimal array sequence and least mean square (LMS), recursive
least square (RLS), and sample matrix inversion (SMI) algorithms are used
for beam generation of the TSA and the algorithms are DE-LMS, DE-RLS and
DE-SMI. A maximum of 48% energy savings is achieved. Using the DE-LMS,
DE-RLS and DE-SMI algorithms, TSA achieved maximum SLL reduction of 11 dB,
11 dB and 9 dB, respectively.

Currently, there is a great extent of academic research focused on evaluating
fatigue among drivers due to its growing recognition as a major contributor
to vehicle tragedies. Combining advanced features and machine learning
techniques, signals from the electroencephalogram (EEG) can be analyzed to
efficiently detect fatigue in the shortest possible time. This study
presents an innovative approach to detect driver fatigue states utilizing
ensemble-based machine learning techniques from EEG signals. Two ensemble
models (Ensemble-based RUSBoosted Decision Trees and Ensemblebased Random
Subspace Discriminant) were applied and compared. The study utilized an
online EEG dataset of 12 individuals, with data collected during normal and
fatigued driving conditions and Fast Fourier Transform was applied for
feature extraction. The Ensemble-based RUSBoosted Decision Trees model
achieved superior performance with 98.53% classification accuracy, compared
to 83.13% for the Random Subspace Discriminant model. Multiple performance
metrics were used for evaluation model performance. Finally, the proposed
Ensemble-based RUSBoosted Decision Trees model outperformed Ensemble-based
Random Subspace Discriminant model and existing conventional methods for
fatigue state detection. This research contributes to the development of
more accurate and reliable fatigue detection systems, which could
potentially improve road safety by identifying fatigued drivers in
real-time.

Published: January 2025

Aeroponics is a modern farming technology for soilless potato cultivation
that enables the efficient production of high-quality pre-basic seed
potatoes (minitubers). In this system, the roots and underground stems
(stolons) of the potato plants grow within closed modules, suspended in a
fine mist of a nutrient-rich solution that continuously recirculates. This
setup enables the formation of numerous minitubers with a length greater
than 10 mm during the growing period. Our study aimed to evaluate the impact
of the genotype and origin of the planting material on minituber production
in an aeroponic facility in Guca, Serbia. Three potato cultivars were
analyzed: Cleopatra, Kennebec, and D?sir?e, using two types of planting
material: acclimated microplants and plants derived from the previous
season?s minitubers. The plants were cultivated aeroponically from late May
to December 2019, with a planting density of 24 plants per square meter and
harvest intervals of approximately 14 days. The D?sir?e cultivar produced
the highest average number of minitubers per plant (19.89), followed by
Kennebec (15.71) and Cleopatra (11.05). The average weight of minitubers was
significantly greater in plants grown from last season?s minitubers compared
to plants grown in vitro. The Kennebec plants originating from minitubers
achieved the highest yield of 10.27 kg per square meter. Additionally, the
plants originating from minitubers consistently produced tubers throughout
the entire cultivation period in the aeroponic growing system.

Published: January 2025

INTRODUCTION: Patients with chronic obstructive pulmonary disease (COPD) have a characteristic problem of a comorbid and combined pathology, which impedes the objective assessment of the severity of patients’ condition. Of special attention is COPD in patients with overweigh and obesity, since the adipose tissue not only worsens the pulmonary dysfunction, but indirectly enhances oxidative damage to cells, especially in hypoxic conditions. Therefore, assessment of the level of markers that directly characterize the degree of tissue damage in the oxidative distress, is interesting as a possible way to objectify the state of comorbid patients with COPD.
AIM: Assessment of the level of spontaneous oxidatively modified proteins (SP OMP) and reserve adaptive potential of oxidative modification of proteins (RAP OMP) in blood plasma of patients with COPD with normal and excessive weight in non-infectious exacerbation.
MATERIALS AND METHODS: The study included 70 patients aged 40 to 70. The first (main) group: 29 men with COPD in the period of non-infectious exacerbation. The second (control) group: 41 respondents without respiratory diseases (32 women, 9 men). Each group was divided into 2 subgroups (body mass index (BMI) ≥ 25 kg/m2 and BMI < 25 kg/m2). All participants of the study underwent a general clinical examination and spirometry. Blood was taken before the treatment. The SP OMP level was determined spectrophotometrically in reaction with 2,4-dinitrophenylhydrazine. The level of RAP OMP was determined as the ratio of the obtained SP OMP values to metal-induced OMP. The differences were considered statistically significant at р < 0.05.
RESULTS: In the COPD group, the levels of SP OMP and RAP OMP were higher compared to the control. In the subgroup of COPD with BMI ≥ 25 kg/m2, the level of SP OMP was statistically significantly higher than in the subgroup with BMI < 25 kg/m2, no reliable differences were obtained in the level of RAP. In the subgroup of COPD with overweight, reliable relationships between SP OMP and BMI were found. No reliable differences were obtained in the levels of SP OMP and RAP OMP in smokers and non-smokers with COPD. The RAP OMP level was higher in 3-degree COPD than in 2-degree COPD. No differences in the level of SP OMP were found between 3-degree COPD and 2-degree COPD.
CONCLUSION: Non-infectious exacerbation of COPD is associated with increase in the content of carbonylated blood plasma proteins. Excessive body weight in patients with COPD in non-infectious exacerbation is associated with a larger increase in the oxidative stress markers.
