Advancing Pediatric Growth Assessment with Machine Learning: Overcoming Challenges in Early Diagnosis and Monitoring
Authors: Rodriguez-Marin Mauro , Orozco-Alatorre Luis Gustavo
Published: February 2025

This article explores the transformative role of machine learning (ML) in pediatric growth assessment, emphasizing the early diagnosis and monitoring of growth disorders. A logistic regression algorithm, developed using R, analyzes biometric and demographic data to identify anomalies in children's growth patterns. The study employs a cross-sectional dataset comprising real- world data from Stanford Medicine Children’s Health and references from reputable sources to model growth variations in children aged 6 to 13. The methodology includes a Systematic Literature Review (SLR) to identify key trends, complemented by data preprocessing techniques such as cleaning, normalization, and feature selection to enhance model performance. The results show that logistic regression achieves an accuracy of 94.65% and a sensitivity of 91.03%, significantly improving the accuracy and timeliness of diagnosing growth anomalies compared to traditional methods. The study concludes that ML, particularly logistic regression, offers promising applications in pediatric health by enhancing diagnostic precision and operational efficiency. However, challenges remain related to data quality, clinical integration, and privacy concerns. Future research should focus on improving data diversity, model interpretability, and external validation to support clinical decision- making. The algorithm and related data are available in a GitHub repository to promote transparency, reproducibility, and collaborative development within the scientific community.

The study examined the fabrication and characterization of nanosponges (NS) laden with polyoxometalates (TiW11Co) with the intention of targeting malignancy. By employing the emulsion solvent diffusion technique, TiW11Co-NS were generated by combining polyvinyl alcohol (PVA) and ethyl cellulose (EC) in different concentrations. Significant numerical results encompassed a hydrodynamic particle diameter of 109.5 nm, loading efficiencies reaching 85.9%, and zeta potentials varying from -24.91 to -27.08 (mV). Scanning and transmission electron microscopy were employed to validate the TiW11Co-NS porous structure and surface morphology. The results of the stability investigations indicated that TiW11Co-NS exhibited prolonged sturdiness. Investigation examining the inhibition of enzymes revealed that TiW11Co-NS exhibited enhanced effectiveness against TNAP. Pharmacological evaluations of TiW11Co-NS demonstrated improved cytotoxicity and apoptotic effects in comparison to pure TiW11Co, thereby indicating their potential utility in targeted cancer therapy. In vivo investigations involving mice revealed that TiW11Co-NS caused a more substantial reduction in tumor weight and increased survival rates in comparison to pure TiW11Co. The resemblance of TiW11Co for crucial proteins associated in cancer proliferation was featured through molecular docking, thereby supporting its therapeutic potential. TiW11Co-laden nanosponges demonstrated superior stability, enzyme inhibition, cytotoxicity, and in vivo anticancer efficacy, underscoring their potential for targeted cancer therapy.

Published: February 2025

Renewable energy sources are becoming increasingly popular due to their advantages over fossil fuels, their economic benefits, and the growing environmental concerns. Researchers are particularly focused on understanding the factors that affect the efficiency of various energy sources. This paper explores the relationship between renewable energy consumption and trade openness from 1990 to 2018 among the top 15 countries that consume the most renewable energy. The study also considers economic growth, natural resources, capital, and financial globalization as additional factors influencing renewable energy use. To analyze the data, the paper utilizes advanced panel data techniques, including the dynamic Seemingly Unrelated Regression (DSUR) and Dimutrescu-Hurlin panel bootstrap causality methods. The findings reveal cross-sectional dependence and slope heterogeneity in the model. The results show that trade openness, economic growth, and capital investment promote renewable energy consumption, while financial globalization tends to reduce it. Additionally, the study finds one-way causality from trade openness, economic growth, natural resources, capital, and financial globalization to renewable energy consumption. These insights can inform the development of renewable energy policies in the countries examined.

Published: February 2025

Bioactive restorative materials are crucial for promoting remineralization and protecting dental tissues through ion release. This study examines how pH and temperature influence the short- and long-term ion (F−, Ca2+, Sr2+, OH-, Si and PO43-) release from seven commercial materials: Cention Forte Filling Material, Cention Primer, Stela Self Cure, Riva Light Cure HV, Riva Self Cure, Equia Forte HT Fil, and Fuji IX GP Fast. Disks were prepared according to the manufacturers' instructions, immersed in buffer solutions at pH 4.8, 6.8, and 8.8, and stored at 37°C and 44°C. Ion release was measured after 1-, 7- and 28-days using ion chromatography and mass spectrometry. Results revealed that ion release was significantly affected by pH, temperature, and exposure time. The highest fluoride (40.14 ± 0.32 mg/L) and calcium (74.23 ± 0.37 mg/L) releases were observed in Riva Light Cure at pH 4.8 and 44°C after 28 days, with the highest strontium release (5.87 ± 0.06 mg/L) occurring under the same conditions. In contrast, silicon release peaked in Cention Forte Filling (31.72 ± 0.68 mg/L) at pH 4.8 and 37°C. These findings highlight the impact of environmental factors on material performance, assisting clinicians in selecting optimal restorative materials for long-term dental health.
Allosterism in p53 – Can AI Solve the Puzzle?
Authors: Zawacka Joanna , Behzadi Malihe
Published: February 2025

Intrinsically disordered p53 is a promising target for precision oncology. p53 undergoes structural changes that induce long-chain fluctuations, known as allosterism. Allosteric shifts regulate p53 translation, stability, or transcription activity. The 2024 Nobel Prize in Chemistry recognises advancements in computational protein design and structure prediction through AI innovations. Yet, current AI-based tools might not be sufficient in unravelling the complexity of allosteric regulation in p53 - a knowledge essential for turning p53 into a feasible therapeutic target.
EEG-Based Neuroinflammation Diagnosis and Its Role in Learning Disabilities
Authors: Eroglu Gunet
Published: February 2025

Learning disabilities (LDs) are complex neurodevelopmental conditions influenced by genetic, epigenetic, and environmental factors. Emerging research highlights the role of maternal autoimmune conditions, perinatal stress, and vitamin D deficiency in promoting neuroinflammation, which disrupts brain development. Chronic neuroinflammation, driven by activated microglia and astrocytes, is associated with synaptic dysfunction and cognitive impairment. Electroencephalography (EEG) biomarkers provide a non-invasive approach for detecting neuroinflammatory patterns, enabling early diagnosis and targeted intervention. This study explores the diagnostic potential of EEG in identifying neuroinflammatory states linked to LDs, focusing on theta, gamma, and alpha oscillations as key indicators of disrupted neurophysiology. Artificial Neural Networks (ANNs) are employed to classify EEG patterns, achieving high diagnostic accuracy. By integrating neurophysiological and inflammatory markers, this approach advances precision medicine for neurodevelopmental disorders.

Published: February 2025

Background: periodontal disease is a multifactorial infectious pathology that affect dental supporting tissues, impacting the health and quality of life of patients. Assessing chewing efficiency before and after periodontal therapy is crucial to better understand its impact on the quality of life of periodontal patients. Aim: to determine whether basic periodontal therapy improves masticatory ability and efficiency in patients with mild to moderate periodontitis.
Methods: a prospective, longitudinal, case series study was carried out in 42 periodontal patients treated at the University Odontology Clinic. Masticatory efficiency before and after basic periodontal treatment was assessed using both objective (HueCheck Gum Test) and subjective (Quality of Masticatory Function questionnaire: QMFq) methods.
Results: significant improvements (P = 0.0001) were observed in periodontal variables like as hygiene index (HI), probing depth (PD), and clinical attachment level (CAL), as well as in the initial and final QMFq total score (P = 0.045). In addition, significant differences were found in post-treatment QMFq scores related to parafunctional habits (P = 0.046) and facial pattern, especially in meat consumption (P = 0.042), fruits and vegetables (P = 0.007, P = 0.044).
Conclusions: basic periodontal treatment does not improve masticatory efficiency of patients with mild-moderate periodontitis objectively, evaluated by means of the test of mixing two chewing gums, but it does subjectively.
The Origin of Life in the Early Continental Crust: A Comprehensive Model
Authors: Schreiber Ulrich
Published: February 2025

Continental rift zones on the early Earth provided essential conditions for the emergence of the first cells. These conditions included an abundant supply of raw materials, cyclic fluctuations in pressure and temperature over millions of years, and transitions of gases between supercritical and subcritical phases. While evidence supports vesicle formation and the chemical evolution of peptides, the mechanism by which information was stored remains unresolved. This study pro-poses a model illustrating how interactions among organic molecules may have enabled the encoding of amino acid sequences in RNA. The model highlights the interplay between three key molecular components: a proto-tRNA, the vesicle membrane, and short peptides. The vesicle membrane acted as a reservoir for hydrophobic amino acids and facilitated their attachment to proto-tRNA. As a single strand, proto-tRNA also served as proto-mRNA, enabling it to be read by charged tRNAs. Through the replication of this information and the assembly of RNA strands, the first catalytically active peptides could form, thereby enhancing the long-term sta-bility of vesicles. This model further outlines how these vesicles may have evolved into the ear-liest cells, with enzymes and larger RNA molecules giving rise to tRNA and ribosomal struc-tures. Shearing forces may have facilitated the first cellular divisions, representing a pre-LUCA stage.

Published: February 2025

Phytotelmata are aquatic microenvironments formed by the accumulation of water and organic matter in cavities of plants. These microenvironments serve as breeding sites for various species of mosquitoes, including some of epidemiological importance. Our objective was to identify the mosquito fauna in these microenvironments and to analyze variations in mosquito fauna diversity between bromeliads, tree holes and bamboo internodes in Cantareira State Park, São Paulo, Brazil, where there have been reports of yellow-fever epizootics in non-human primates and circulation of plasmodia. Collections were carried out monthly from February 2015 to April 2017. Bromeliads showed greater mosquito species richness and diversity than tree holes and bamboo internodes, as well as a very different composition. Of the 11 genera collected and 49 taxa identified, Culex (Carrolia) iridescens, Cx. ocellatus, Cx. (Microculex) imitator and Anopheles (Kerteszia) cruzii were the most abundant. The phytotelmata in CSP were found to allow a diverse mosquito fauna to develop, including An. cruzii and the sylvatic yellow fever virus vector Haemagogus leucocelaenus. The finding of these epidemiologically important species highlights the key role played by phytotelma breeding sites as places of refuge and species maintenance for these vectors in green areas close to urban centers.

The galvanostatic intermittent titration technique (GITT) was applied to NMC622 positive electrodes, with Electrochemical Impedance Spectroscopy (EIS) performed at quasi-equilibrium conditions determined by cutoff criteria based on relaxation rates. Below an open-circuit voltage (OCV) of 3.8 V, the cutoff criterion of 0.1 mV h−1 was reached after approximately 8 hours. However, above 3.8 V, a non-saturating voltage decay was observed, increasing up to ∼0.56 mV h−1 above 4.1 V during charging steps. This persistent voltage decay upon subsequent discharging steps led to non-monotonic relaxation behavior. A pulse time of 10 minutes did not satisfy the t dependence required for GITT kinetic analysis. Instead, the initial 36-second transients were extended for chemical diffusivity evaluation, aligning with the Warburg-like response observed in EIS, consistent with the sequential reaction-diffusion assumption. GITT analysis for solid-state diffusivity is ineffective for spherical active particles dispersed in porous electrodes and performs even worse due to liquid-phase diffusion within the pores, where t+=0.3. The apparent SOC-independent chemical diffusivity obtained from GITT across both low and high OCV ranges suggests that the process is dominated by liquid-phase diffusion. The application of the physics-based three-rail transmission line model (TLM) developed by Gaberšček et al. in EIS holds practical potential for deconvoluting the two diffusion kinetics.

Recordando desde el presente la historia del Perú: análisis de los procedimientos de la obra teatral Los héroes de mi patria
Authors: Abrill Federico
Published: February 2025

The theater of memory addresses key events in the development of society and its proposals increasingly seek to investigate both the topics it addresses and the way it is staged. Los héroes de mi patria belongs to this theatricality and has a very particular mechanism. In it, the author reviews his archive and, at the same time, the country's historical archive, reviewing the life of his military family. By analyzing its dramaturgy, staging and the vision of its creator, it has been possible to study the procedures that this staging proposes to address both themes, finding a dynamic mechanism where the intimate intersects with the reconstruction of official history. A form of approach that invites innovation in the theatricality of memory and its experience in the audience.
Relationship between innovation climate and entrepreneurial attitude in International Business and Administration students: a study case about the Universidad Continental de Peru
Authors: Ramirez-Lazo Oscar Horacio , Acobo Moreno Katya Veronica , Ramirez Lazo Paulo César
Published: February 2025

The economic growth of a society is mainly due to the entrepreneurship and innovation developed by its members, and universities play a fundamental role in promoting entrepreneurship and spaces where innovation is developed. Peru is one of the countries with the greatest intention to undertake in Latin America and the world, but it is also characterized by a high rate of discontinuity in entrepreneurship. Therefore, the objective of this study is to determine the level of influence of the innovation climate on the entrepreneurial attitude of students studying Business Administration and International Business at Universidad Continental through a quantitative study of 219 students between 18 and 24 years of age and both sexes. The student’s Entrepreneurial Attitude Scale and the Open Innovation Climate Scale were used. The following results were obtained by applying these instruments: the greater the innovation climate, the greater the entrepreneurial attitude, besides, a degree of influence cannot be considered as representative between the dimensions of each variable. The comparative results between the first and fifth year students showed that the most notable difference is seen in the final year students due to the negative relationship between the outward dimensions’ focus and innovation, and flexibility with some dimensions of the entrepreneurial attitude variable. It was not identified how representative the degree of influence between both variables is. We conclude that students perceive the level of innovation and flexibility, as well as reflexivity, as high, but as low, depending on the outward focus that the university presents; In relation to the entrepreneurial attitude, a representative degree of influence was not identified between the dimensions of each variable.

Ethically informed urban planning: measuring distributive spatial justice for neighbourhood accessibility
Authors: Nelson Ruth , Warnier Martijn , Verma Trivik
Published: February 2025

Studies in urban accessibility have advanced our understanding of social and spatial inequalities in the distribution of urban resources in cities worldwide. In response, prominent discourse is shifting to embed justice in urban planning. Ethical principles have historically been employed by philosophers to guide thinking about reshaping society towards more fair and just outcomes. In this work, we present the Mapping Accessibility for Ethically Informed Urban Planning (MAP) framework. Map operationalises three metrics of distributive spatial justice based on Equality, Utilitarianism and Rawls’ Egalitarian principles to compare the implications of choosing different values of justice to evaluate neighbourhood accessibility. We apply MAP to three diverse cities located in the Netherlands, Mexico and South Africa, modeling each city as an urban network model, integrating public transportation, land use, and street networks. Across the cases and ethical perspectives, we find that the implications of defining justice is mediated by a neighbourhood’s proximity to local mixed land use for shorter commuting times. Whereas for longer commutes, it is dependent on a neighbourhood’s access to the Central Business District of each region, through transportation infrastructure. The findings underscore the scale, contextual and value-reliant nature of distributive spatial justice. MAP offers a means to facilitate comparative analysis within urban planning processes, highlighting different ethical concerns for debate by stakeholders and citizens.

Tidal wetlands are hotspots of soil accumulation due to high sedimentation rates and low soil oxygen concentrations that inhibit organic matter decomposition1. Accordingly, tidal wetlands can sequester “blue carbon” at much higher rates than other ecosystems2,3 helping to offset human emissions. Organic carbon burial is tightly linked to the cycling of nitrogen, which is a key pollutant and limiting nutrient for many ecosystems4–6. Yet, the current global burial rate of “blue nitrogen” and how it may respond to future change remain uncertain. We assembled a global database of 8012 soil nitrogen measurements from 255 tidal wetland sites and found that the relationship between soil carbon and nitrogen concentrations was strikingly consistent but differed between the two dominant types of emergent tidal wetlands – marshes and mangroves. Leveraging extensive knowledge of blue carbon accumulation, we estimated that tidal wetlands, which cover less than 0.1% of the Earth’s surface, bury 3.2 Tg N yr-1, representing 13-15% of marine nitrogen burial. This rate could more than triple globally by 2100 if wetland elevation increases with accelerating sea-level rise. Alternatively, if wetlands become submerged and shorelines erode, nitrogen sinks could reverse and become sources, exacerbating coastal pollution.

Lung cancer is a primary malignant tumor of the lung that poses the greatest health risk to the population. An immune-associated protein family gene called T-cell immunoglobulin and mucin domain 1 (TIM-1) can be utilized as an immunological marker to help diagnose lung cancer. However, the correlation between TIM-1 gene polymorphisms and the risk of lung cancer has not been reported, so the present study focused on genotyping TIM-1 gene polymorphic loci (rs1501909, rs2036402, rs2270924, rs870581) by TaqMan probe assay, the aim was to investigate the correlation between the TIM-1 gene single nucleotide polymorphisms (SNPs) and genetic susceptibility to lung cancer. Using a case-control study method, a total of 191 lung cancer patients in Dali, Yunnan Province were included as the experimental group and 109 healthy individuals as the control group. Statistically analyzed by constructing multiple genetic models, the difference in the distribution of allele G at the rs2036402 locus of the TIM-1 gene between the two groups was statistically significant (OR = 0.585;95%CI = 0.389–0.880, P = 0.010), and individuals carrying the G allele had an increased risk of developing lung cancer. Linkage disequilibrium analysis further indicated that strong linkage disequilibrium existed among rs1501909, rs2036402, rs2270924 and rs870581.
Qualitative Understandings of the Persistent Use of Traditional Contraceptive Methods Using Socio-Ecological Model among Older Reproductive-age Women in Bangladesh
Authors: Abedin Mashiat , Hossain Mohammad Bellal
Published: February 2025

Background: The continued use of traditional contraceptive methods (TCM) among older reproductive-aged women (aged 35–49 years) in Bangladesh poses a significant public health issue. Existing research in Bangladesh suggests that women of this age use TCM more than their younger counterparts do. However, the reason why TCM use is higher among Bangladeshi older reproductive-age women is yet to be explored. The current study attempted to understand the use of TCM among Bangladeshi women aged 35 years or older.
Methods: This qualitative study used purposive sampling from the Khulna district to conduct ten in-depth interviews among women aged 15-49 years and seven key informant interviews among family planning service providers. The socio-ecological model was adopted in this study. Data was collected in January 2024. The interviews were audio-recorded and transcribed verbatims afterward. Thematic data analysis was performed.
Results: The study found that women’s poor knowledge and fear of the side effects of modern contraceptive methods and perceptions related to the effectiveness, risk and benefits, ease of use, and cost shaped the use of TCM at the individual level. The interpersonal factors included the influence of spouses, mothers-in-law, and peer groups. Community norms and beliefs were pivotal as well. Institutional-level factors included providers’ attitudes, health facility-related issues such as distance from the house, waiting in queues, and unavailability of products, and policy-level influences such as lack of updated policy molded the TCM use among older reproductive age women in Bangladesh.
Conclusion: A complex interplay of various level factors shapes the use of TCM in Bangladesh. As a result, comprehensive reproductive health education programs should be considered so that women can make informed choices about the use of contraceptives and switch from traditional to modern contraceptive methods, such as long-acting methods. This will ultimately lead to better reproductive health outcomes in Bangladesh.

Thermoelectric materials allow direct conversion between heat and electricity and may be useful for power generation or solid-state refrigeration. However, improving thermoelectric performance is challenging because of the strong coupling between the electrical and thermal transport properties. We demonstrate a new super-gravity-field re-melting fabrication technology that synergistically optimizes the thermoelectric performance. Using a super-gravity field, the brittle (Bi,Sb)2Te3 alloy undergoes unusual plastic deformation and forms mounts of microstructure defects, which is rarely observed in common fabrication process. As a result, the microstructure reconstruction and carrier concentration optimization were simultaneously realized, resulting in an ultra-low lattice thermal conductivity of < 0.25 W/m K and a record-high figure of merit of > 1.91 in the BiSbTe alloy. The strong enhancement of thermoelectric properties was validated in a thermoelectric module with high conversion efficiency of 6.4% and corresponding output power density of 0.34 W cm2 when subjected to a temperature difference of 185 K. This work highlights a new super-gravity strategy to achieve a high thermoelectric performance, which may be applicable to other thermoelectric materials.

Balancing the logistics of raw material procurement, manufacturing operations, and product distribution within the constraints of a microgrid-powered environment are among the main optimization challenges of cement supply chains. This study develops a bi-objective robust fuzzy Mixed-Integer Linear Programming (MILP) model to design a microgrid-based cement supply chain network under pervasive uncertainty. Electrical energy demand plays a key role in the cement industry which is addressed through local energy resources in the microgrid structure of the suggested network in this work. To address the significance of sustainability in the problem, the objectives are to respectively maximize the total profit made by the operations in the cement supply chain network and minimize the total dust of the cement supply chain resulting from the operations, which are then treated using the Weighted Sum Method (WSM). An illustrative example is then investigated to demonstrate the applicability, validity and complexity of the developed model. Accordingly, a set of sensitivity analyses on the cement supply chain key parameters along with uncertainty parameters is conducted to render useful managerial perspectives and tools for decision-making. It is revealed that our methodology is able to design and plan the microgrid-based cement supply chain in less than 2 seconds.

Fast food consumption has become a significant aspect of senior high school students' lifestyles, often associated with impulsive purchasing behavior. However, its specific influence on the buying patterns of Grade 12 students remains insufficiently investigated. A descriptive-correlational research design was utilized, targeting 116 Grade 12 students from Mapúa Malayan Colleges Mindanao, selected through stratified random sampling. Data were collected using a validated 18-item questionnaire focusing on fast food consumption factors and impulsive buying behavior, administered online with prior institutional approval. The findings reveal that taste, convenience, and satisfaction significantly influence fast-food consumption among Grade 12 students at Mapúa Malayan Colleges Mindanao, with taste receiving the highest mean rating (4.457). Similarly, impulsive buying, fast food chains, and promotional signage strongly impact buying behavior, with a moderate positive correlation (r = 0.558, p < .001) observed between fast-food consumption and impulsivity. These results highlight the role of fast-food factors in shaping consumer habits, aligning with prior studies emphasizing taste, accessibility, and marketing strategies. The study reveals that taste, convenience, and satisfaction drive fast-food consumption, significantly influencing impulsive buying behavior among students. It highlights the importance of fostering financial awareness and self-control to mitigate impulsive spending and suggests exploring broader demographic factors to better understand student purchasing decisions.

Electromagnetic precursor anomalies are an important indicator for earthquake prediction, with numerous observations, simulations, and theoretical studies available. However, the generation process of electromagnetic waves, particularly their frequency characteristics, before an earthquake has not been thoroughly studied. This issue is crucial in determining whether the earthquake electromagnetic precursor signal can penetrate the stratum, significantly impacting the theoretical research on earthquake prediction. This paper explores the frequency of electromagnetic waves generated in the seismogenic zone before an earthquake through elastic mechanics and microcracks. Simulation results indicate that the lowest frequency of electromagnetic waves is 1341 Hz, sufficient for propagation from the seismic source zone to the surface. The simulated abnormal current near the seismic source zone is about 106 A, consistent with observations. While our work is just a starting point, this study offers theoretical support for the generation and propagation of earthquake electromagnetic precursor signals.

Background
Hepatitis D virus (HDV) is an incomplete viral particle that lacks the ability to replicate and disseminate autonomously. Its replication and transmission are contingent upon Hepatitis B virus (HBV). Research has unveiled that the involvement of HDV and HBV in hepatocellular carcinoma development is not a mere additive effect, but rather they synergistically interact through multiple mechanisms to drive hepatocellular carcinoma progression. By investigating the interplay between HDV and liver cancer, researchers can gain a better understanding of hepatocellular carcinoma pathogenesis, thereby offering novel insights and approaches for early diagnosis and treatment.
Methods
We retrieved the corresponding Microarray datasets from the GEO database and conducted differential gene expression (DEGs) analysis using the GEO2R tool. Subsequently, we constructed a protein-protein interaction (PPI) network utilizing the STRING database and assessed the significance of key interactions within this network by employing the MCODE module to identify core nodes. For these pivotal genes, we performed expression level analysis and survival curve analysis based on TCGA-related data to elucidate their relevance to hepatocellular carcinoma. Furthermore, we employed univariate and multivariate analysis of variance to evaluate whether these genes may serve as independent factors for staging liver cancer. Additionally, KEGG pathway enrichment analysis was carried out in order to explore the signaling pathways associated with these genes.
Results
The study revealed that the expression levels of six genes, namely BUB1B, CCNB1, CDC20, CDK1, DLGAP5, and NUF2, were significantly upregulated in patients diagnosed with HDV-related hepatocellular carcinoma (HCC), which was strongly associated with an unfavorable prognosis for individuals suffering from HCC.
Conclusion
The present study has successfully identified a series of hub genes that potentially participate in the pathogenesis of HCC associated with HDV, and these genes can serve as reliable indicators for prognostic assessment.
