Test–Retest Reliability of Temporal Processing Tests in Normal Hearing Young Adults
Authors: Ghosh P. G. Vipin , Nayaka Y. N. Harshitha
Published: January 2025

Introduction:

It is essential to use tests that exhibit high levels of sensitivity, specificity, and effectiveness to identify Central Auditory Processing Disorder. However, data on the reliability of these tests when administered repeatedly are limited in the literature. Furthermore, earlier researchers have reported variable reliability on a variety of auditory processing tests. Practice effect may be one of the contributing factors to this variability. The aim of the present study was to evaluate the test–retest reliability of various temporal processing tasks in young adults with normal hearing sensitivity and to study the practice effect on repeated measurements.

Methods:

A repeated measure design was utilized for estimating the test–retest reliability and practice effect on the duration pattern test and forward masking test. The study involved 30 young adults with normal hearing abilities. Half of the participants were tested twice with a break of 1 week, and the rest of the participants underwent testing thrice in a session with a break of 15 min between each trial.

Results:

Statistical analysis revealed good consistency between the trials spaced 1 week apart, while there was no significant difference observed between trials spaced 15 min apart on both tests. This indicated good reliability and a lack of practice effect for both test procedures.

Conclusions:

The study concludes that both tests have high test–retest reliability when measured 1 week apart. The absence of practice effect on closely spaced subsequent trials suggests that repeated exposure to the test does not significantly impact performance.
Response to adjunctive antibiotic therapy along with nonsurgical periodontal therapy in the treatment of peri-implantitis and chronic periodontitis patients: An exploratory review
Authors: Sethi Geetanshu , Grover Vishakha , Gupta Jyoti , Jain Ashish
Published: January 2025

Objectives:

This review was conducted to assess and compare whether there is a difference in response to adjunctive systemic and locally delivered antibiotics along with nonsurgical periodontal therapy (NSPT) in the treatment of peri-implantitis (PI) and chronic periodontitis (CP).

Materials and Methods:

A systematic search of literature on the predefined criteria was conducted using PubMed, Embase, and Scopus. Probing pocket depth, bleeding on probing, clinical attachment level, and microbial load reduction were selected as primary outcomes, whereas plaque index and gingival index were evaluated as secondary outcomes. Standard Cochrane risk-of-bias tools were used for the quality assessment of the included studies, and a qualitative data synthesis was conducted owing to the observed heterogeneity of the extracted data.

Results:

Adjunctive systemic and local antibiotics with NSPT resulted in additional beneficial effects in cases of both CP and PI, with greater improvement observed in cases of CP as compared to PI. Even for treatment of PI, among local antibiotics, minocycline was the only antibiotic with some significant adjunctive benefits, when used with NSPT as documented.

Conclusion:

Within the limitations of the review, it is concluded that the adjunctive use of antibiotics with NSPT offers a beneficial effect in the management of both CP and PI; however, there is insufficient direct evidence regarding the comparative efficacy of the adjunctive antibiotic therapy along with NSPT for the treatment of PI and CP.
Influence of surface texture on osteogenic differentiation of dental pulp stem cells: An in vitro study
Authors: Rajpurohit Komal , Dodwad Vidya , Kharat Avinash , Belludi Spoorthi , Pharne Pooja , Marium Sarah
Published: January 2025

Background:

In comparison with perfectly machined surface implants, surface topographic modifications like roughness accelerate the osteogenesis of dental pulpal stem cells (DPSC). This greatly enhances bone-implant contact and osteogenic potential of the stem cells. Hence, the aim of the current study was to evaluate and compare the differentiation and proliferation potential of stem cells obtained from dental pulp on sand-blasted and acid etched implant discs surfaces.

Materials and Methods:

Stem cells from dental pulp were extracted from the premolar region of oral cavity. Titanium discs that measured one centimeter in diameter and three millimetres in thickness were used as investigation surfaces. Titanium surface disc were acid etched and sandblasted. Investigation had three group: acid etched (Group A), sandblasted (Group B), and standard control group, i.e., cells treated with osteogenic induction media only (Group C). In Group C, mesenchymal stem cells (MSCs) were treated with osteogenic induction medium without any titanium disc and these cells were used as standard controls. To identify which modified implant surface had greater potential for proliferation, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was performed using the explant culture. MTT assay assessed the viability of the cells as a function of its redox potential. This was followed by recognition of the stem cells for CD90, CD73, and CD 105 markers using flow cytometry with RUNX2 antibody on days 7 and 21 of incubation. The isolated cells were stained using 1% alizarin red stain to identify the number of stem cells per square centimeter area under the light microscope.

Results:

The osteogenic differentiation of both the materials was compared with standard control (MSCs treated with osteogenic differentiation media only). The osteoblastic cells on the acid-etched and sand-blasted implant surface disc had an almost identical capacity for proliferation till the MTT assay but according to the results of the alizarin red staining there was a slightly higher proliferation potential on acid etched surfaces compared to the sand blasted surfaces. Therefore, acid etched surfaces showed higher potential of osteogenic differentiation of DPSCs compared with sand-blasted surfaces.

Conclusion:

In comparison with perfectly machined surface implants, topographic surface modifications such as roughness can accelerate the osteogenesis of DPSC in
vitro.
Exploring the Efficacy of Tai Chi as an Adjunct Therapy to Conservative Management of Knee Osteoarthritis: A Case Report
Authors: Kashyap Divya , Sandilya Abhishek Kumar , Kumari Reena , Chaturvedi Maitri
Published: January 2025

Abstract

This study aimed to evaluate the effectiveness of Tai Chi as a supplement to traditional treatments for knee osteoarthritis (OA). A 48-year-old woman diagnosed with knee OA participated in a 12-week Tai Chi program, alongside conventional physiotherapy. The outcomes were measured using the Western Ontario and McMaster Universities Arthritis Index score. The use of Tai Chi as a conservative management strategy showed promising results in alleviating pain, improving physical function, and enhancing the quality of life. These findings suggest that Tai Chi could be integrated into clinical practice for the conservative management of knee OA. However, further research is required to confirm these results and assess the long-term effects of Tai Chi on knee OA.
Phototherapy in vitiligo
Authors: Bishnoi Anuradha , Hamzavi Iltefat
Published: January 2025

Vitiligo is a chronic dermatological condition characterized by the progressive loss of melanocytes, leading to depigmented patches on the skin. Phototherapy has emerged as a cornerstone in the management of vitiligo, offering a promising approach to disease stabilization and repigmentation. This review explores the efficacy, mechanisms, and clinical applications of various phototherapy modalities in treating vitiligo. Narrowband ultraviolet B therapy is highlighted as the most effective and widely used phototherapeutic option, promoting melanocyte proliferation and migration. Excimer laser, another phototherapy modality, offers targeted treatment with fewer side effects and has shown success in localized vitiligo. Additionally, combination therapies involving phototherapy and topical and systemic agents (such as psoralens, corticosteroids, calcineurin inhibitors, azathioprine, and other systemic immunomodulators, basic fibroblast growth factor/decapeptide and Janus kinase inhibitors) and surgical management have demonstrated enhanced repigmentation outcomes. The safety profile of phototherapy, including potential risks such as photodamage and carcinogenesis, is critically analyzed. The review underscores the importance of individualized treatment plans and ongoing research to optimize phototherapy protocols, ultimately aiming to improve the quality of life for vitiligo patients.
Bratteli diagrams in Borel dynamics
Authors: Bezuglyi Sergey , Jorgensen Palle E. T. , Karpel Olena , Sanadhya Shrey
Published: January 2025

Bratteli–Vershik models have been very successfully applied to the study of various dynamical systems, in particular, in Cantor dynamics. In this paper, we study dynamics on the path spaces of
generalized
Bratteli diagrams that form models for non-compact Borel dynamical systems. Generalized Bratteli diagrams have countably infinite many vertices at each level; thus, the corresponding incidence matrices are also countably infinite. We emphasize differences (and similarities) between generalized and classical Bratteli diagrams. Our main results are as follows. (i) We utilize Perron–Frobenius theory for countably infinite matrices to establish criteria for the existence and uniqueness of tail-invariant path space measures (both probability and

\sigma

-finite). (ii) We provide criteria for the topological transitivity of the tail equivalence relation. (iii) We describe classes of stationary generalized Bratteli diagrams (hence Borel dynamical systems) that (a) do not support a probability tail-invariant measure and (b) are not uniquely ergodic with respect to the tail equivalence relation. (iv) We describe classes of generalized Bratteli diagrams which can or cannot admit a continuous Vershik map and construct a Vershik map which is a minimal homeomorphism of a (non-locally compact) Polish space. (v) We provide an application of the theory of stochastic matrices to analyze diagrams with positive recurrent incidence matrices.
Combinations of parabolically geometrically finite groups and their geometry
Authors: Udall Brian
Published: January 2025

In this paper, we study the class of parabolically geometrically finite (PGF) subgroups of mapping class groups, introduced by Dowdall–Durham–Leininger–Sisto. We prove a combination theorem for graphs of PGF groups (and other generalizations) by utilizing subsurface projection to obtain control on the geometry of fundamental groups of graphs of PGF groups, generalizing and strengthening methods of Leininger–Reid. From this result, we construct new examples of PGF groups and provide methods for how to apply the combination theorem in practice. We also show that PGF groups are undistorted in their corresponding mapping class groups.
Profinite subgroup accessibility and recognition of amalgamated factors
Authors: Wykowski Julian
Published: January 2025

We investigate
accessible subgroups
of a profinite group

G

, that is, subgroups

H

appearing as vertex groups in a graph of profinite groups decomposition of

G

with finite edge groups. We prove that any accessible subgroup

H \leq G

arises as the kernel of a continuous derivation of

G

in a free module over its completed group algebra. This allows us to deduce splittings of an abstract group from splittings of its profinite completion. We prove that any finitely generated subgroup

\Delta

of a finitely generated virtually free group

\Gamma

whose closure is a factor in a profinite amalgamated product

\hat{\Gamma}= \overline{\Delta}\amalg_{K} L

along a finite

K

must be a factor in an amalgamated product

\Gamma = \Delta \ast_{\chi} \Lambda

along some

\chi \cong K

. This extends previous results of Parzanchevski–Puder, Wilton and Garrido–Jaikin-Zapirain on free factors.
H-unitality of smooth groupoid algebras
Authors: Francis Michael D.
Published: January 2025

We show that the convolution algebra of smooth, compactly-supported functions on a Lie groupoid is H-unital in the sense of Wodzicki. We also prove H-unitality of infinite order vanishing ideals associated to invariant, closed subsets of the unit space. This furthermore gives H-unitality for the quotients by such ideals, which are noncommutative algebras of Whitney functions. These results lead immediately to excision properties in discrete Hochschild and cyclic homology around invariant, closed subsets. This work extends previous work of the author establishing the Dixmier–Malliavin theorem in this setting.
A filtered generalization of the Chekanov–Eliashberg algebra
Authors: Avdek Russell
Published: January 2025

We define a new algebra associated to a Legendrian submanifold

\Lambda

of a contact manifold of the form

\mathbb{R}_{t}\times \mathrm{W}

, called the
planar diagram algebra
, and denote it by

\mathrm{PDA}(\Lambda, \mathcal{P})

. It is a non-commutative, filtered, differential graded algebra whose
filtered stable tame isomorphism class
is an invariant of

\Lambda

together with a partition

\mathcal{P}

of its connected components. When

\Lambda

is connected,

\mathrm{PDA}

is the Chekanov–Eliashberg algebra. In general, the

\mathrm{PDA}

differential counts holomorphic disks with multiple positive punctures using a combinatorial framework inspired by string topology.
Clinical features of abnormal α-fetoprotein in 15 patients with chronic viral hepatitis B after treatment with antiviral drugs
Authors: Jiang Man-Lei , Xu Fei , Li Jin-Long , Luo Jia-Yu , Hu Jiang-Ling , Zeng Xian-Qiang
Published: January 2025

BACKGROUND

Liver function of chronic hepatitis B (CHB) patients is essentially normal after treatment with antiviral drugs. In rare cases, persistently abnormally elevated α-fetoprotein (AFP) is seen in CHB patients following long-term antiviral treatment. However, in the absence of imaging evidence of liver cancer, a reasonable explanation for this phenomenon is still lacking.

AIM

To explore the causes of abnormal AFP in patients with CHB who were not diagnosed with liver cancer.

METHODS

From November 2019 to May 2023, 15 patients with CHB after antiviral treatment and elevated AFP were selected. Clinical data and quality indicators related to laboratory testing, imaging data, and pathological data were obtained through inpatient medical records.

RESULTS

All patients had increased AFP and significantly elevated IgG. Cancer was excluded by imaging examination. Only four patients had elevated alanine aminotransferase, 10 had elevated aspartate aminotransferase, nine had elevated total bilirubin, and two had antinuclear antibodies. The liver biopsy and histopathological examination indicated that 14 patients had rosette, moderate, or higher interfacial inflammation, lymphocyte infiltration, and severe hepatic fibers (11 cases), which was consistent with the pathological features of autoimmune hepatitis (AIH). After 8-12 week of hormone therapy, the levels of AFP and IgG, and liver function returned to normal (P < 0.05).

CONCLUSION

For patients with CHB and elevated AFP after antiviral treatment, autoimmune hepatitis should be considered. CHB with AIH is clinically insidious and difficult to detect, and prone to progression to cirrhosis. Liver puncture pathological examination should be performed when necessary to confirm diagnosis.
Management of chylous ascites after liver cirrhosis: A case report
Authors: Chen Zong-Qiang , Zeng Shu-Jun , Xu Chun
Published: January 2025

BACKGROUND

Chylous ascites is an uncommon condition, occurring in less than 1% of ascites cases. It results from traumatic or obstructive disruption of the lymphatic system, causing the leakage of thoracic or intestinal lymph into the abdominal cavity. This leads to the accumulation of a milky, triglyceride-rich fluid. In adults, malignancy and cirrhosis are the primary causes of chylous ascites. Notably, chylous ascites accounts for only 0.5% to 1% of all cirrhosis-related ascites cases. At present, there is a limited understanding of this condition, and effective timely management in clinical practice remains challenging.

CASE SUMMARY

This case report presents a patient with hepatic cirrhosis complicated by chylous ascites, who had experienced multiple hospitalizations due to abdominal distension. Upon admission, comprehensive examinations and assessments were conducted. The treatment strategy focused on nutritional optimization through a low-sodium, low-fat, and high-protein diet supplemented with medium-chain triglycerides, therapeutic paracentesis, and diuretics. Following a multidisciplinary discussion and thorough evaluation of the patient’s condition, surgical indications were confirmed. After informing the patient about the benefits and risks, and obtaining consent, a transjugular intrahepatic portosystemic shunt procedure was performed, successfully alleviating the abdominal swelling symptoms. This article details the clinical characteristics and treatment approach for this uncommon case, summarizing current management methods for hepatic cirrhosis complicated by chylous ascites. The aim is to provide valuable insights for clinicians encountering similar situations.

CONCLUSION

Optimizing nutrition and addressing the underlying cause are essential in the treatment of chylous ascites. When conservative approaches prove ineffective, alternative interventions such as transjugular intrahepatic portosystemic shunt may be considered.
Potential mechanisms and therapeutic prospects of the association between Helicobacter pylori infection and metabolic dysfunction-associated steatohepatitis
Authors: Gou Guo-E , Li Ting , Liu Chen-Rui , Meng Ting , Li Ya-Ping
Published: January 2025

Helicobacter pylori (H. pylori ) infection is a known inducer of various gastrointestinal diseases, including gastritis, gastric ulcers, and gastric cancer. However, in recent years, research on the potential association between H. pylori infection and metabolic dysfunction-associated steatohepatitis (MASH) has been scarce. This large-scale multicenter study, covering more than 360 hospitals across 26 medical systems in the United States, systematically evaluated the association between H. pylori infection and MASH. This paper reviews the innovative aspects of this study, discusses its significance in the current research field of H. pylori and liver diseases, analyzes potential molecular mechanisms, and suggests future research directions and therapeutic prospects.
Helicobacter pylori infection as a contributing factor to metabolic dysfunction-associated steatohepatitis: A population-based insight
Authors: Li Chao , Nan Jiang , Xu Bo-Tao
Published: January 2025

This letter discusses the research conducted by Abdel-Razeq et al , highlighting a significant association between Helicobacter pylori (H. pylori ) infection and metabolic dysfunction-associated steatohepatitis (MASH) in individuals with a prior history of H. pylori infection. Using a comprehensive patient database, the study establishes an independent correlation between H. pylori and an elevated risk of MASH, even after adjusting for coexisting conditions such as obesity, type 2 diabetes, and dyslipidemia. Notably, the findings suggest that H. pylori may worsen liver pathology through inflammatory pathways, contributing to hepatic insulin resistance and lipid accumulation. Although the study provides strong evidence for this association, limitations related to diagnostic heterogeneity indicate a need for further research to clarify the underlying mechanisms and to explore the potential roles of genetic and microbiome factors in this relationship.
High metabolic dysfunction-associated steatotic liver disease prevalence in type 2 diabetes: Urgent need for integrated screening and lifestyle intervention
Authors: Jin Lei-Yang , Wang Kai , Xu Bo-Tao
Published: January 2025

This letter discusses the recent study by Mukherjee et al [1], which identifies a significant prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) among newly diagnosed type 2 diabetes mellitus (T2DM) patients in Bihar, India, and underscores the pressing need for integrated MASLD management within T2DM care. With 72.3% of the study cohort affected by MASLD, implementing routine liver function tests and ultrasound screenings is recommended as a standard practice in diabetes care, especially in regions with high prevalence rates. The study also advocates for dietary and lifestyle modifications, particularly the reduction of saturated fats, to slow MASLD progression. Patient education on monitoring body mass index and waist circumference, coupled with the integration of these metrics into digital health records, could enhance patient involvement and support proactive health management. Moreover, the letter emphasizes the advantages of developing a region-specific MASLD risk model that incorporates local dietary patterns and socioeconomic factors. Continued research into genetic and environmental determinants of MASLD remains essential for advancing our understanding of its etiology and informing targeted public health strategies.

ESTIMATING A PRELIMINARY DEMAND MODEL FOR CORN MOVEMENTS FROM THE U.S. EAST COAST AND GULF TO EAST ASIA, FUTURE CORN TRAFFIC, AND DECARBONIZATION PROCESS
Authors: Ho Javier , Bernal Paul
Published: January 2025

Corn is the second most important component of the grain segment after soybeans, averaging close to 35.7% of total grain traffic through the Panama Canal. The objective of this paper is to attempt to fit a preliminary general demand model for corn traffic through the Panama Canal using Ordinary Least Square (OLS). The corn traffic estimated is the U.S. Gulf and East Coast to East Asia, particularly China, Japan, South Korea, and Taiwan, and the research hypothesized the possible variables that may explain the downward trend inthe movements of corn in this route between October 2004 to September 2022. Canal costs, U.S. Gulf freight rates, U.S. Gulf and Pacific Northwest grains inspections and the energy index were the most important explanatory variables in the study. This research also discusses the future of corn traffic through the waterway in terms of alternative sources, routes, and possible demand for corn, and explores the decarbonization process impacting the Panama Canal and the U.S. corn supply chain. For the literature review, the research is leveraging on previous estimation of demand functions for grains and the decarbonization studies related to the maritime industry, and examine papers related to Panama Canal shipping demand, thus closing the gap on the literature about transportation demand through the waterway.

Authors: Zhaken Nurkhan , Moldabekova Aisulu , Jianhui Feng
Published: January 2025

The integration of various transportation modes is a critical aspect of global supply chain management, commonly referred to as multimodal logistics. This method is utilised to optimise cost, time, and environmental impact. This study employs a bibliometric analysis to investigate the evolving trends and the essential role of transportation in multimodal logistics. The analysis emphasises the unique advantages of trucking, rail, maritime shipping, and air transport. The study utilises keywords from the Scopus database to search for materials and analyses them based on the year of discovery, industry, producing authors, and state. The analysis is restricted to research subjects and focuses on highly specific areas, such as modelling processes, digitalisation, ecological impact, and regional performance evaluation. The literature significantly focuses on the challenges of coordinating multiple transportation modes, technological advancements, and sustainability. The study identifies prevailing trends, key research areas, and future directions, differentiating between multimodal and intermodal logistics and their respective implementation challenges and advantages. Multimodal logistics, a vital sector of the economy, also supports other sectors by reducing direct economic costs through efficient linkages between manufacturing and extractive industries. The study emphasises the importance of empirical research, technological integration, and sustainable practices in advancing multimodal logistics.
AN ANALYTICAL HIERARCHY PROCESS (AHP) APPROACH FOR SELECTION OF OFFSHORE SUPPLY BASES: KEMAMAN VERSUS TOK BALI IN MALAYSIA
Authors: Zolkaflee Mohd Iszhar
Published: January 2025

This paper explores and identifies a key element in the offshore supply chain and the oil and gas industry, the offshore logistic system, which includes offshore supply bases. This shore supply base is the logistics hub for all drilling and oil and gas activity. It functions as a central warehouse and a forward base for supplying cargo and needed supplies to offshore installations, and it offers critical services to facilitate offshore operations. Because of its advantageous position in Southeast Asia, Malaysia has become a prominent participant in the worldwide oil and gas sector. The nation’s offshore supply bases, with oil and gas platforms operating in different locations along the eastern shores, have become crucial centres for the sector. This study aims to identify the key factors in supply base selection by oil and gas operators by performing a comparative analysis of two significant offshore supply bases in Malaysia, specifically Kemaman and Tok Bali. The analytical hierarchy process (AHP) has been used for stakeholders to make multi-criteria decisions. The method will prioritise four main criteria for supply base selection: Geographical location of Offshore Supply Base, Infrastructure and facilities, services provided and charges, and Regulatory considerations were used with twelve sub-criteria to ascertain which supply base is most favourably situated to meet the increasing demands of the oil and gas industry in the region, all of which determine the operational efficiency and cost-effectiveness of offshore operations. The analysis revealed that the Geographical component is the most significant, followed by Facilities and infrastructure, Service and costs, and Regulatory, respectively. Based on the score, the attribute with the highest level of importance is the Distance to MTJDA & MVCAA (Northern Section) Oil & Gas Platform. This is followed by Service, Berth facilities, Distance to the oil and gas Platform at Terengganu Water (Southern Section), Outsourced / Inland Area, Warehousing, Storage Facilities, Crew Change, Customs, Charges, Port Authority, and ISPS compliances in that order. The findings of this study will aid oil and gas companies and players in making informed decisions regarding the selection of onshore supply bases. By examining the factors influencing the choice of supply base and their respective advantages, companies can make informed decisions that contribute to their overall success in a competitive global market.

Water is a compound composed of hydrogen (H?) and oxygen (O?), with turbidity caused by suspended particles such as clay and sewage. This study aims to reduce the turbidity of the Bengawan Solo River using the jar test method with pre-sedimentation and no pre-sedimentation treatment. The results showed that pre-sedimentation decreased the mean turbidity from 55.08 NTU to 30.16 NTU. The primary coagulant Al?(SO?)? and the auxiliary coagulant Ca(OH)? affect the turbidity and pH of the water. The pH value was close to neutral (6.07) achieved at a concentration of 60 ppm with pre-sedimentation. This method is effective in reducing turbidity and has the potential to be applied in large-scale water treatment.

The presence of harmful gases such as H?S and mercaptans in the natural gas purification process requires safe handling to avoid the risk of equipment damage and danger to the environment and occupational safety. This study aims to analyze occupational safety risks in the V-0301 Combination Column at the Caustic Treater Unit (CTU) of CPP Gundih, PT Pertamina EP Cepu Asset 4 Zone 11 using the Hazard and Operability Study (HAZOP) method. Observed processes include pre-wash, extraction, and water wash, with NaOH as the primary solvent and demineralized water to remove impurities from natural gas. The analysis is carried out by identifying potential hazards and process deviations based on operating parameters such as pressure, temperature, and flow. The results point to several key risk scenarios, such as the potential for corrosion due to excessive NaOH concentrations and failure of pressure control systems. Risk mitigation recommendations include improved control systems, periodic inspections, and safety training for operators. The study contributed to the improvement of occupational safety and operational reliability of CTU units in natural gas processing facilities

Fire risk is a work safety problem that often occurs in an industry. The pipe rack area at PT XYZ has a large potential fire risk due to the presence of flammable materials and sustainable production activities. The identification and analysis process regarding the causes of fire incidents is urgently needed to formulate preventive measures. By using the fishbone diagram analysis method, the root cause of potential fires can be identified and the Failure Mode and Effect Analysis (FMEA) method can be found out the value of the severity. The results of the study show that six basic causes affect the occurrence of fires. Through FMEA, several high-risk failure modes can be identified and prioritized as cracks in pipe joints in pipe fitting components. Recommendations for preventive measures include increasing occupational safety training, regular equipment maintenance, improving fire early detection systems, and implementing occupational safety standards.

This study aims to analyze the role of mobile technology and artificial intelligence (AI) in improving the effectiveness of corporate communication and corporate relationships with consumers. With the rapid development of digital technology, companies are required to adopt innovations that are able to answer consumer needs quickly and personally. The study examines the application of AI, such as chatbots and sentiment data analysis, as well as mobile technology as the main interaction platform. Data is collected through a literature study method that includes journals, articles, and recent case studies. The results show that AI contributes to brand responsiveness through fast, automated customer service and data-driven analysis of consumer needs. On the other hand, mobile technology provides flexibility for consumers to access services and interact with brands at any time. The combination of these two technologies creates a more personalized and relevant experience, but it also poses challenges such as data privacy protection and limitations in understanding consumers' emotional context. This study concludes that the integration of mobile technology and AI in corporate communication is an effective strategic step to improve public connectivity. However, successful implementation requires a balanced approach between automation and human interaction to build consumer trust on an ongoing basis

Introduction. According to the recent sociological survey data, 77% of Ukrainians have felt stressed or very nervous, particularly those with manifestations of post-traumatic stress disorder. Respondents name a full-scale war as the dominant reason for this feeling. According to the results of a survey conducted during the first year of the full-scale invasion, 6% fewer respondents reported feeling stressed. Benzodiazepines are the most commonly used class of anxiolytic medications for treating stress and anxiety. However, prolonged use is associated with numerous risks. In this way, doctors and patients are increasingly turning to herbal remedies as a safe alternative to benzodiazepines. This becomes particularly important for military personnel in wartime conditions. Prolonged stress and emotional strain can lead to the development of serious mental disorders. Safe herbal anxiolytics can reduce anxiety, promote psychological resilience, improve the quality of life for military personnel, and allow them to perform their combat missions more effectively without the risk of addiction or impaired concentration caused by the side effects of synthetic preparations.
Purpose. To study and analyse the state of pharmacological research on herbal objects, considering their anxiolytic actions and related constituents. To assess the prospects for practical application of plant-based medications in the treatment of stress and anxiety, for both civilians and military personnel.
Materials and Methods. The bibliosemantic method was used in conducting the research. The study materials included scientific publications in professional journals.
Results. An analysis of the pharmacodynamic and clinical studies on plant-based medicines derived from Passiflora incarnata L., Crataegus species, Valeriana officinalis L., Matricaria chamomilla L., and Withania somnifera L. was conducted. It was determined that the studied plant-based remedies exhibit anxiolytic activity and demonstrate clinical efficacy in treating anxiety, stress, and related disorders.
Conclusions. Based on the results of the analysis, herbal medicines appear promising for use in the treatment and prevention of stress-related conditions. Depending on the severity of the condition, these herbal remedies could present a safe alternative to synthetic anxiolytics, especially for long-term use. The next phase of research should focus on developing a final medicinal formulation, defining its target quality profile, and outlining a conceptual plan for the manufacturing process.
