Case Series on Ochronotic Arthropathy: An Incidental Finding in Osteoarthritis Hip, Review of Literature
Authors: A Kavitha , V Kavita , Kar Shreya
Published: May 2024

Ochronotic arthropathy, an infrequent ailment characterized by the buildup of oxidized and polymerized metabolites of homogentisic acid, presents a distinctive challenge in the medical realm. The affinity of homogentisic acid for collagen, a vital constituent of connective tissues, underpins the pathogenesis of this condition. Joints, crucial components of the body's architecture, become the primary focus of this disorder. Invariably, the axial spine joints are its initial target, followed by a subsequent involvement of the knees, shoulders, and hips, ultimately ushering in degenerative transformations. The objective of this article is to cast a spotlight on the infrequently encountered ochronotic arthropathy, with specific emphasis on its manifestation in the femoral head. This report showcases two incidental cases wherein the head of the femur becomes an unforeseen site of affliction. The intricacies of ochronotic arthropathy extend beyond its rarity, as it challenges conventional understanding and diagnostic approaches. By examining its manifestation within the femoral head, we strive to unravel the nuances of its impact on this particular joint. This exploration not only expands our comprehension of the condition itself but also underscores the critical importance of recognizing its potential to manifest in atypical locations. As medical practitioners, a deeper understanding of such unconventional occurrences equips us to better diagnose, manage, and treat ochronotic arthropathy, ultimately enhancing patient care and outcomes.
Incorporating non-local anyonic statistics into a graph decomposition
Authors: Mühlhauser Matthias , Kott Viktor , Schmidt Kai Phillip
Published: May 2024

In this work we describe how to systematically implement a full graph decomposition to set up a linked-cluster expansion for the topological phase of Kitaev’s toric code in a field. This demands to include the non-local effects mediated by the mutual anyonic statistics of elementary charge and flux excitations. Technically, we describe how to consistently integrate such non-local effects into a hypergraph decomposition for single excitations. The approach is demonstrated for the ground-state energy and the elementary excitation energies of charges and fluxes in the perturbed topological phase.

The results of a joint inversion of the data of controlled source radio-magnetotelluric soundings (CSRMT) and electrical resistivity tomography (ERT), obtained at the Khanovei permafrost test site near Vorkuta, are presented. The geological section in the work area is composed of Quaternary fluvio-glacial, lacustrine-glacial and alluvial deposits up to 60 m thick, overlying a sequence of sandstones, siltstones and mudstones of Permian age. The CSRMT survey was carried out using a grounded electrical line 480 m long as a source in the frequency range 1-1000 kHz. The results of various inversion options were compared: 1) isotropic one-dimensional (1D) inversion of CSRMT data; 2) isotropic separate two-dimensional (2D) inversion of CSRMT and ERT data; 3) joint anisotropic 1D inversion of CSRMT and ERT data. Based on the results of a joint anisotropic inversion of CSRMT data in the far and intermediate zones of the source and ERT data, a vertical anisotropy associated with horizontal layering of frozen Quaternary clay deposits in the depth range from 2 to 15-20 m was revealed and its parameters (horizontal and vertical resistivity and anisotropy coefficient) were determined. On the geoelectric section obtained from the ERT data, the thickness of the anisotropic layer of frozen clayey deposits is significantly overestimated. The middle part of the section, in the depth range from 15-20 to 60-70 m, is characterized by relatively low resistivity values (tens of ohmmeters). This is consistent with the results of previous studies, which established that the upper part of the Permian sediments is in a thawed state and is fractured and water-saturated. A high-resistivity layer (hundreds of ohmmeters) was revealed at the base of the geoelecric section according to CSRMT data. A significant increase in the resistivity of Permian rocks with depth is confirmed by the data of vertical electrical soundings previously performed in the Khanovey area.

The response of river catchments located on the territory of Russia to climate change in recent decades has been expressed in the emergence of multidirectional trends in the series of annual runoff, maximum water discharges and the value of winter runoff. However, the response of small and medium-sized rivers to the ongoing climate warming has been poorly studied, in contrast to large rivers. In this paper, a comprehensive analysis of the climatic and hydrological characteristics of small and medium-sized rivers of Central Yakutia as well as an assessment of the climate change impact on the river runoff characteristics in various conditions of the region were carried out. It has been established that the revealed positive trends in temperature correspond to the trends typical for the rest of the Russian Federation. The response of the runoff of small and medium-sized rivers to climate change is most significant in the winter-spring months of the year: there is an increase in runoff in the spring and winter periods and for the year as a whole. A feature of the response of the river catchments of the study area in comparison with the European part of Russia and southern Siberia is the presence of statistically significant trends in the series of annual water discharges for most of the studied water gauges. The most noticeable changes (as a percentage of the base period) occurred in the annual runoff of small rivers, because small rivers respond most quickly to external influences. Its expressiveness is determined not only by the degree of changes in climatic characteristics, but also by the features of runoff formation in the watersheds of the study area, in particular, the presence of permafrost.
Moscow — Berlin: The Photomontage in Illustrated Magazines of the 1920s
Authors:   St. Petersburg State University of Industrial Technologies and Design, Laptev Vladimir V.
Published: May 2024

This paper presents the historical experience of organizing the visual space of an illustrated magazine and its artistic design by means of photography. Attention is focused on the application of photomontage in the demonstrated samples of printed publications of the Soviet Union and Weimar Germany in the 1920s. Special attention is paid to the features of the artistic appearance of the Soviet illustrated magazine “Smena” (Moscow), which began publishing in 1924, and the German workers’ illustrated newspaper “Arbeiter-Illustrierte Zeitung” (Berlin), which published photographic materials since 1925. These publications became a symbol of the use of photomontage in the first post-revolutionary decade in the world illustrated periodicals. In the years of the avant-garde, photomontage became a method of forming an artistic composition through the efforts of the Berlin Dada and Soviet constructivists. And in propaganda works it becomes a method of constructing a fact that convinces and motivates the reader. The replacement of illustration by photography and photomontage was accelerated in illustrated magazines. This happened especially vividly in the 1920s, when new artistic techniques for creating imagery. The result of the study is the revealed specificity of the use of photomontage within the framework of two paradigms: Dadaism and constructivism, and their influence on the artistic appearance of Soviet and German illustrated magazines of the 1920s. The predominance of mainly constructivist ideas is shown both in the magazine “Smena” and in “Arbeiter-Illustrierte Zeitung”, despite the German roots of avant-garde photomontage. The result of the comparative analysis was the thesis about the initial influence of Moscow on Berlin within the framework of the visual strategy of propaganda periodicals. At the end of the decade under review, this vector began to change its orientation, and already Soviet illustrated magazines were looking at the work of German colleagues in terms of photomontage developments. And here the undisputed leadership in visual innovations belonged to “Arbeiter-Illustrierte Zeitung”.
The Indian Contract Act — background and case law
Authors:   Università degli Studi di Milano, Acquarone Lorenza
Published: May 2024

This article aims to illustrate the background and the case law of the Indian Contract Act, enacted in 1872. It also tries to provide a comparison between the law introduced in India and the model which is the English Common Law of Contract based on the English law of the time. Indeed, the provisions contained in the Indian Contract Act are more advanced and more organically conceived than the English Common Law of Contract. Pillars of the Common Law of Contract such as the doctrine of consideration, the doctrine of frustration and the doctrine of economic duress are found in the Indian act in an improved version. Indian courts applied them consistently in the majority of cases. Even today, in a few exceptional cases, the Indian courts appear to be influenced by English case law to such an extent that they do not comply with the innovative aspects of the Indian Contract Act. Recently the pandemic of Covid-19 causing hindrance to the performance of many contracts raised questions such as the existence of force majeure able to nullify the contract and in certain cases it triggered the applicability of the doctrine of frustration. Such situations are codified by the Indian Contract Act and case law is available. New needs have arisen in the field of marriage law such as prenuptial agreements, which may apparently be deemed valid if they pass the test of public order as stated in the Indian Contract Act.
The role of culture in international commercial arbitration
Authors:   Nagoya University Graduate School of Law, Colombo Giorgio Fabio
Published: May 2024

International commercial arbitration is the primary mean for settling international disputes of a business nature. Because of its very structure, this procedure happens across borders and, needlessly to say, cultures. As a consequence highly technical nature of international commercial arbitration, the debate about “culture” in this field has adopted a fairly narrow approach, and is generally limited to issues relating to clashes of different procedural styles and models (e. g. the discovery of evidence, which is very different in Common Law and Civil Law jurisdictions), studies about the arbitration community itself (a still quite small and tightly-knit group of professionals), or to the arbitration-friendliness of a given country. Yet, the definition of “cultural issues” in international commercial arbitration should be addressed from a much broader perspective. This article intends to fill this gap, by tackling questions related to “law and culture” in arbitration under three possible patterns: issues affecting the arbitrator, issues relating to the applicable law, and issues relevant for the arbitration procedure.
Decolonizing Law: Language and anthropology in the Lusosphere
Authors:   New Vision University of Tbilisi, Gandini Edoardo
Published: May 2024

In the Lusophere, under the appearance of homogeneity of law, due to the influence of Portuguese law, are hidden linguistic and anthropological aspects that are still untied from the State institutions and formal law of the new independent Countries. Thus, this paper, after an overview of the historical events of Portuguese law — from the presence of ius commune in Portugal, to the colonial era, to the post-independence legal systems — focuses on the linguistic and anthropological aspects of millions of people, only conventionally of Portuguese mother tongue and who regulate their lives according to spontaneous unwritten rules. Comparing within the Lusophere, this paper carries out its observation from three different perspectives: law, language, and anthropology. Portuguese now ranks sixth in terms of the number of native speakers and is spread across at least four continents; therefore, it is surprising to observe the scant consideration within the comparative studies for the law and language of Lusophone areas, with few exceptions and mostly confined to native authors. Even more unexplored is the field of comparative law among Portuguese-speaking countries, and except for a few contributions between Portuguese and Brazilian law, attention to Angola, Mozambique, Guinea Bissau, Cape Verde, São Tomé e Princípe, Equatorial Guinea and East Timor is sporadic, rare or nonexistent. This scenario appears to be due to a kind of self-referentiality of the Lusophone legal systems, mainly due to a strong academic dependence on Portuguese universities, a common erudite and administrative language, and a low diffusion of foreign language study. A decolonization of law is for these reasons desirable and, instead of being perceived an intimidating path, should be seen as a chance for new development opportunities.
Home Composting and Factors for Potential Adoption: Knowledge and Persuasion
Authors: Nieto Garibay Alejandra
Published: May 2024

The increase in municipal solid waste has been considered a worldwide issue and the organic fraction represents the largest share of total solid waste. Home composting is an efficient way to convert organic waste into fertilizer, but so far this technique has not been widely adopted by society. Therefore, this paper aims to identify the factors of knowledge and persuasion that boost the adoption of home composting through Rogers' Diffusion of Innovations Theory. A survey was conducted with respondents from the city of La Paz B.C.S. Frequency analysis, crosstabulations, and ordinal logistic regression was performed for data analysis. Most of the respondents were found to have awareness and knowledge of composting. Among the factors promoting adoption were gender, garden space, time investment, willingness to teach others, and perception as a simple activity.

Authors: Atlatenco Ibarra Quetzalli , Hernández González Salvador
Published: May 2024

Las pensiones por jubilación otorgadas a través de los principales sistemas de seguridad social en México son de capitalización individual y contribución definida, lo que implica que el monto de estas dependerá de la cantidad que cada persona haya logrado acumular a lo largo de su vida en una cuenta individual de ahorro para el retiro. La gran mayoría de las personas agrupadas en la denominada “Generación Millennial” solamente tendrán esta opción para jubilarse por lo que es relevante estudiar la tenencia de una cuenta especializada de ahorro para el retiro. Por medio de una regresión logística binaria se estudia la probabilidad de poseer dicho instrumento financiero con base en algunas variables predictoras como sexo, nivel educativo, situación conyugal, entre otras. Se halló que la probabilidad de tener cuenta individual para el retiro es mayor en el caso de los hombres, con nivel de estudios superior, quienes son casados o viven en pareja, en el Noroeste de México en localidades mayores a 15,000 personas y que no padecen de vulnerabilidad financiera.
Developing improved machine learning methods to predict the flow characteristics through vertical and horizontal transitions in open channels
Authors: Gad Manal , Abd-Elhamid Hany , Zeleňáková Martina , Marie Hanaa Salem , Nassar Wael O.
Published: May 2024

Transitions in an open channel refer to the change in flow behavior due to changes in the channel geometry. Determining flow characteristics through transitions is an important topic as it is necessary to guarantee the ideal hydraulic performance of water structures with low costs. This research focuses on the flow characteristics through vertical and horizontal transitions through experimental study and then utilizing machine learning to predict the flow characteristics. The proposed framework aims to develop both the cascade-forward artificial neural network (CFANN) model and the regression model to enhance the prediction of flow characteristics. The first model developed modifies the CFANN using dandelion optimizer (DO) to determine the ideal CFANN configuration. The second model used gene expression programming to develop statistical equations. The obtained CFANN–DO model has proven high accuracy in predicting the flow rates at various water loads and speeds achieving a coefficient of determination of approximately 100% for training data and 99.5% for testing data. Finally, predicting the characteristics of vertical and horizontal transitions in open channels is a critical issue. Manipulating these transitions can create a habitat for aquatic organisms, reduce erosion, and improve the overall environment.

Inflammation is an individual’s physiological response to a sequence of physical, chemical, or infectious
stressors acting mainly to provide localized protection. Although inflammation is a protective and thus
beneficial process, its excess or prolonged action can be harmful to the body. An increasing number of the population
worldwide are changing their lifestyles, which leads to a rise in inflammatory diseases, such as atherosclerosis,
angina pectoris, myocardial infarction, ulcerative colitis, cancer, and many more. Their treatment is
based majorly on the pharmacological approach. However, natural products or bioactive compounds are of
great significance in inflammation therapy because they show minimum side effects and maximum bioavailability.
Therefore, it is critical to investigate bioactive substances that can modify target functions associated
with oxidative stress defense and might be used to achieve various health benefits. This review accentuates the
essence of bioactive chemicals used in the treatment of inflammation and other inflammatory illnesses. These
bioactive compounds can be of any origin, such as plants, animals, bacteria, fungi, marine invertebrates, etc.
Bioactive compounds derived from plant sources, such as glycyrrhizin, lignans, lycopene, resveratrol, indoles,
and phenolic and polyphenolic compounds, work mainly by reducing oxidative stress and thereby preventing
various inflammatory disorders. A large diversity of these anti-inflammatory bioactive compounds has also
been discovered in marine environments, giving rise to an increase in the interest of various scientists in
marine invertebrates and microbes. The vast diversity of microbes found in the marine environment represents
an enormous supply to extract novel compounds, such as from bacteria, cyanobacteria, fungi, algae, microalgae,
tiny invertebrates, etc. In the present review, an attempt has been made to summarize such novel bioactive
compounds that help prevent inflammatory responses via different mechanisms of action.

:

Gene editing technology, particularly Clustered Regularly Interspaced Short Palindromic Repeats
(CRISPR)/CRISPR-associated protein 9 (Cas9) has transformed medical research. As a newly developed
genome editing technique, CRISPR technology has strongly assisted scientists in enriching their comprehension
of the roles of individual genes and their influences on a vast spectrum of human malignancies. Despite
considerable progress in elucidating obesity's molecular pathways, current anti-obesity medications fall short
in effectiveness. A thorough understanding of the genetic foundations underlying various neurobiological pathways
related to obesity, as well as the neuro-molecular mechanisms involved, is crucial for developing effective
obesity treatments. Utilizing CRISPR-based technologies enables precise determination of the roles of
genes that encode transcription factors or enzymes involved in processes, such as lipogenesis, lipolysis, glucose
metabolism, and lipid storage within adipose tissue. This innovative approach allows for the targeted suppression
or activation of genes regulating obesity, potentially leading to effective weight management strategies.
In this review, we have provided a detailed overview of obesity's molecular genetics, the fundamentals of
CRISPR/Cas9 technology, and how this technology contributes to the discovery and therapeutic targeting of
new genes associated with obesity.

and Esophageal Cancer
Authors: Khaghani Armin , Kasiri Karamali , Heidari-Soureshjani Saeid , Sherwin Catherine M.T. , Mardani-Nafchi Hossein
Published: May 2024

Background:

Esophageal cancer is a malignant tumor with a low survival rate. Statins, commonly
prescribed for their lipid-lowering effects, have been suggested to possess potential chemopreventive properties
against various cancers, including esophageal cancer.

Objectives:

This systematic review studied the association between statin intake and esophageal cancer.

Methods:

To conduct this systematic review and meta-analysis, we reviewed studies published between 1980 and
June 2023 in Web of Science (WOS), Embase, MEDLINE/PubMed, Scopus, and Cochrane Library databases
according to the PRISMA guidelines. Data extraction, quality assessment, and statistical analyses were performed
using predefined protocols. We used various statistical tests conducted by Stata statistical software. Statistical
significance was considered significant at p < 0.05.

Results:

Twenty-one studies were collected and analyzed. The meta-analysis demonstrated that the odds ratio
(OR) of esophageal cancer in patients treated with statins was 0.65 (95% CI: 0.57-0.75, p < 0.001) compared to
the non-receiving group. The ORs for case-control and cohort studies were 0.67 (95% CI:0.54-0.83, p < 0.001)
and 0.62 (95% CI:0.55-0.71, p < 0.001), respectively. The investigation into the relationship between the statins
intake and the incidence of esophageal cancer did not reveal any indication of publication bias according to both
Begg's test (p = 0.966) and Egger's test (p = 0.113).

Conclusion:

The results revealed that the odds of esophageal cancer in patients treated with statins decreased by
35% compared to patients not treated with statins. However, further well-designed prospective studies are needed
to validate these findings and understand the underlying mechanisms of statins in preventing esophageal cancer.

Published: May 2024

Biopharmaceuticals include vaccines, bioengineering drugs, blood products,
genetic engineering drugs, microecological preparations, and recombinant therapeutic
proteins. They are intended for the prevention, diagnosis, and treatment of human
diseases. Biopharmaceuticals are delivered using different drug delivery methods
which include nanoparticles, microparticles, jet injections, depot injections, and pumps.
It can be administered orally or in injectable form. In recent years, most of the
biopharmaceuticals including monoclonal antibodies are available as liquid
formulations. The emergence and re-emergence of infectious diseases require the
development of newer diagnostic tools and pharmacotherapeutic approaches. The
traditional approach may take a long time to get a new lead, whereas the
biotechnological applications may give highly specific antibodies which can minimize
the time of the drug discovery process and these molecules may have high specificity.
In the last few decades, many biopharmaceuticals have been approved for various
indications including cancer treatment. Many countries consider the biopharmaceutical
sector to be one of the most important industries for national growth.
Biopharmaceuticals have wider applications and it is gaining much more attention
clinically than conventional pharmaceuticals. The purpose of the chapter is to highlight
the importance of biopharmaceuticals and their prospects.

Authors: Fauzi Naufal Annas
Published: May 2024

The impact of the spread of the coronavirus disease (COVID 19) affects all people in the world. One of the efforts by the Indonesian government to reduce the spread of the virus is by implementing Large-Scale Social Restrictions (PSBB). The impact of the PSBB can be felt directly by the community in various sectors. The existence of regulations regarding restrictions on large-scale social activities (PSBB) has resulted in a decrease in activity in all fields, one of which is tourism in the Special Region of Yogyakarta. The positive side that can be drawn from social restriction regulations is the potential for reducing pollutants that pollute urban air caused by human activities. This study analyzes data from air quality testing results in the City of Yogyakarta from the Ministry of Environment (KLH) and the number of tourists visiting Yogyakarta from the Yogyakarta City Tourism Office in 2019 to 2020. Based on data obtained from the Yogyakarta City Tourism Office from 2019 to 2019 2020 saw an average decrease in tourist visits by 70% at three tourist sites in the city of Yogyakarta, namely: the Yogyakarta Palace, Taman Pintar, and the Vredeburg Museum. Based on data obtained from the Yogyakarta Special Region Tourism Statistics Report for 2019 and 2020, there has been an average decrease in tourist visits by 71% at ten tourist sites in the City of Yogyakarta. The decrease in tourist visits affects the air quality in the Yogyakarta City environment. This can be proven by improving the quality of ambient air in the City of Yogyakarta in 2020. Reducing the level of carbon monoxide (CO) in the air in the city of Yogyakarta by 12.5%.

Urban farming (UF) has become popular, and several cities are trying to enhance sustainability by improving urban greenery and urban farming. In addition to supporting food security within the area, it benefits the people’s health and well-being and the surrounding environment. This results in a shifting of time consumption from spending time outside, like travelling and shopping, to commuting to activities within home boundaries. Therefore, UF is becoming an activity for residential communities besides working and studying. Therefore, this paper aims to identify the significant Life Cycle Cost (LCC) components concerning the UF practices. The objective of the research is to establish the attributes of UF practice throughout the LC phase. Hence, the findings of the paper indicate the conceptual framework for LCC components concerning the UF practices which are beneficial to practitioners. To achieve this aim, previous studies on types, techniques, and components of UF technology and practices throughout the LC phase, have been explored in both local and international contexts. Thirteen (13) papers from journal and conference papers were reviewed to determine the LCC components of UF according to life cycle (LC) phases. The attribute placed in the respective phase is based on thematic techniques. The paper’s findings indicate that the LCC components occur during Planning, Installation, Management, Maintenance, and Harvesting/ Disposal.

Housing preference among urban dwellers in Kota Kinabalu’s Transit Oriented Development area is an important issue since housing unit prices are often expensive nowadays. Urban dwellers face a wide range of problems, and as they have evolved into the primary segment of the housing market, they have been continuously confronted with housing decisions based on their preferences. Apart from that, preferences for features of the housing units and developments vary among different groups of urban dwellers based on their demographic profiles. This study aims to identify the most common preferences among urban dwellers that influence their housing purchasing decisions in Transit-Oriented Development (TOD) areas. The data was obtained through a questionnaire survey using a convenience sampling approach. Based on 105 working adult-age respondents, the findings indicated that based on the mean and ranking score, the preference aspect that influenced purchasing decisions the most was the neighbourhood and income factor at a 4.98 mean value.

Background

Due to their accessibility and anonymity, web-based counseling services are expanding at an unprecedented rate. One of the most prominent challenges such services face is repeated users, who represent a small fraction of total users but consume significant resources by continually returning to the system and reiterating the same narrative and issues. A deeper understanding of repeated users and tailoring interventions may help improve service efficiency and effectiveness. Previous studies on repeated users were mainly on telephone counseling, and the classification of repeated users tended to be arbitrary and failed to capture the heterogeneity in this group of users.

Objective

In this study, we aimed to develop a systematic method to profile repeated users and to understand what drives their use of the service. By doing so, we aimed to provide insight and practical implications that can inform the provision of service catering to different types of users and improve service effectiveness.

Methods

We extracted session data from 29,400 users from a free 24/7 web-based counseling service from 2018 to 2021. To systematically investigate the heterogeneity of repeated users, hierarchical clustering was used to classify the users based on 3 indicators of service use behaviors, including the duration of their user journey, use frequency, and intensity. We then compared the psychological profile of the identified subgroups including their suicide risks and primary concerns to gain insights into the factors driving their patterns of service use.

Results

Three clusters of repeated users with clear psychological profiles were detected: episodic, intermittent, and persistent-intensive users. Generally, compared with one-time users, repeated users showed higher suicide risks and more complicated backgrounds, including more severe presenting issues such as suicide or self-harm, bullying, and addictive behaviors. Higher frequency and intensity of service use were also associated with elevated suicide risk levels and a higher proportion of users citing mental disorders as their primary concerns.

Conclusions

This study presents a systematic method of identifying and classifying repeated users in web-based counseling services. The proposed bottom-up clustering method identified 3 subgroups of repeated users with distinct service behaviors and psychological profiles. The findings can facilitate frontline personnel in delivering more efficient interventions and the proposed method can also be meaningful to a wider range of services in improving service provision, resource allocation, and service effectiveness.
AI: Bridging Ancient Wisdom and Modern Innovation in Traditional Chinese Medicine

The pursuit of groundbreaking health care innovations has led to the convergence of artificial intelligence (AI) and traditional Chinese medicine (TCM), thus marking a new frontier that demonstrates the promise of combining the advantages of ancient healing practices with cutting-edge advancements in modern technology. TCM, which is a holistic medical system with >2000 years of empirical support, uses unique diagnostic methods such as inspection, auscultation and olfaction, inquiry, and palpation. AI is the simulation of human intelligence processes by machines, especially via computer systems. TCM is experience oriented, holistic, and subjective, and its combination with AI has beneficial effects, which presumably arises from the perspectives of diagnostic accuracy, treatment efficacy, and prognostic veracity. The role of AI in TCM is highlighted by its use in diagnostics, with machine learning enhancing the precision of treatment through complex pattern recognition. This is exemplified by the greater accuracy of TCM syndrome differentiation via tongue images that are analyzed by AI. However, integrating AI into TCM also presents multifaceted challenges, such as data quality and ethical issues; thus, a unified strategy, such as the use of standardized data sets, is required to improve AI understanding and application of TCM principles. The evolution of TCM through the integration of AI is a key factor for elucidating new horizons in health care. As research continues to evolve, it is imperative that technologists and TCM practitioners collaborate to drive innovative solutions that push the boundaries of medical science and honor the profound legacy of TCM. We can chart a future course wherein AI-augmented TCM practices contribute to more systematic, effective, and accessible health care systems for all individuals.
