Authors: Mohd Syafrizal  , Widyanti Rahayu  , Dania Siregar
Published: August 2024

Education in a country is a crucial factor in enhancing human resources. The Gross Enrollment Rate for Higher Education is one of the important indicators used by the government to evaluate the development of the education sector, particularly higher education. Social and cultural diversity, as well as geographical influences, result in varying conditions across different regions, leading to each region having its own unique characteristics, known as spatial heterogeneity. Geographically Weighted Regression (GWR) is a method that can address the problem of spatial heterogeneity. Additionally, a common issue encountered in modeling with many independent variables is multicollinearity, which can lead to high variance in regression parameter estimates and invalid conclusions. Principal Component Analysis (PCA) is a dimensionality reduction method that can address multicollinearity. The aim of this research is to model Gross Enrollment Rate in Higher Education in Central Java using GWR, preceded by handling multicollinearity with PCA. Furthermore, this study aims to determine the factors influencing Gross Enrollment Rate in Higher Education in Central Java. The results, using a fixed Gaussian kernel weighting function, indicate that modeling with PCA and GWR performs better than using the Ordinary Least Square (OLS) method alone, yielding an AIC value of 169.43 and a coefficient determination value  of 96.2%.
Panel Data Regression Modelling Factors Affecting Participation in Indonesia's National Health Insurance Contribution Assistance Program
Authors: Santi Vera Maya
Published: August 2024

National Health Insurance (JKN) is a health insurance system that provides health protection to individuals who have paid premiums (non-PBI) or whose premiums are paid by the government (PBI). JKN participation in Indonesia from 2018 to 2021 has consistently increased, particularly for JKN PBI, yet the program has not achieved the target of 100% membership coverage globally or nationally. A deeper understanding of the factors influencing JKN is crucial to enhance the program's effectiveness and formulate targeted policies. This study aims to analyze the factors affecting the participation of JKN PBI annually in Indonesia. The data used in this study cover the period from 2018 to 2021 and involve 34 provinces in Indonesia, thus forming a panel data structure. A panel data regression model is employed to identify the factors influencing JKN PBI participation. The predictor variables analyzed include income levels, access to health facilities, employed population, and education levels. The results indicate that the most suitable model for determining the factors influencing participation in the National Health Insurance PBI with a significance level of  is the Random Effect Model (REM). The simultaneous and partial tests show that the variables of the employed population and education levels significantly impact JKN PBI participation. Therefore, the REM is considered appropriate and effective in explaining the factors influencing participation in the JKN PBI program. This study provides insights that can help in formulating more targeted policies to enhance the effectiveness of the JKN program in Indonesia.

Published: August 2024

Dengue Hemorrhagic Fever (DHF) is a disease caused by the dengue virus. DHF cases have always been a serious problem every year in Central Java. This study aimed to determine the factors that cause Dengue Hemorrhagic Fever (DHF) in the province of Central Java because cases of DHF in the region become a serious problem every year. The method used for this research is Principal Component Analysis and Factor Analysis using secondary data from the Central Java Provincial Health Office in 2018. The results of the analysis show that 3 factors are causing DHF, namely the population participation factor in health, sanitation factors, and clean drinking water factors. This shows the importance of environmental education to increase population awareness in terms of healthy living and local government intervention is needed in environmental health projects, namely sanitation and clean drinking water This research only uses seven variables that are considered relevant, other variables that may also have an influence are not included in this analysis. This research focuses on a particular year that shows a decreasing trend in cases. This approach offers a fresh and distinct perspective on understanding the dynamics of dengue fever and the factors that contribute to its reduction.

Published: August 2024

Cases of dengue hemorrhagic fever (DHF) generally occur in areas with high temperatures. Central Java Province, Indonesia is one of the regions that has high temperatures, making it vulnerable to dengue cases. The study aimed at grouping DHF endemic areas in Central Java needs to be done to assist the government in determining policies to control or prevent DHF. The cluster analysis method used in this study is Average Linkage. The results showed that there were 3 clusters formed. Cluster A is a cluster with the characteristics of having the highest average percentage of households that have access to safe drinking water. Cluster B is the cluster with the highest average number of protected springs. While cluster C is dominant in 4 factors with the highest average, namely the percentage of households that behave in a clean and healthy life, the percentage of healthy homes, the number of Polindes (Village Maternity Hut), and the percentage of households that have access to proper sanitation. Clusters A and B are clean water type and Cluster C is a sanitation type, where clean water and sanitation are both indicators of environmental health. Therefore, environmental health is closely related to the presence of dengue fever in a community environment. The determination of three clusters was based on the chosen method and criteria. Other methods or criteria might suggest a different optimal number of clusters. The findings are specific to Central Java Province and may not be generalizable to other regions with different environmental and social contexts. In this case, it is necessary to pay attention to the community for environmental health in order to overcome or prevent the occurrence of DHF. where clean water and sanitation are both indicators of environmental health. Therefore, environmental health is closely related to the presence of dengue fever in a community environment.

Authors: Sa'idah Zahrotul Jannah  , Grace Lucyana Koesnadi  , Elly Pusporani
Published: August 2024

Cardiovascular disease is a global threat and is the main cause of death worldwide. More than 17.9 million people died from heart and blood vessel problems. Most of these deaths, around 80%, occurred in countries with low or middle economies, including Indonesia. This research aims to find the most accurate and efficient model for classifying cardiovascular disease data so that cardiovascular disease can be detected early.
This research uses heart failure patient data with predictor and response variables. The response variable has two categories such as passed away and alive. Moreover, predictor variables are obtained from the patient’s behavioral risk factors. Data preprocessing was done before the modeling and divided into 0% training and 20% testing data. Modeling in training data was done with multiple algorithms such as Logistic Regression, Decision Tree, Random Forest, K-Nearest Neighbor (KNN), and Support Vector Machine (SVM). Each model was evaluated with metrics such as Accuracy, Precision, and Recall obtaining the best model.
This study found that the use of all research variables in the classification analysis leads to a decrease in classification performance, so this study used SelectKBest with a total of 8 significant variables. Furthermore, the Random Forest algorithm with optimal parameters using entropy criterion and a maximum depth of 8 is the method with the most optimal performance, achieving a precision of 90.51% for the 'alive' category, recall of 88.27% for 'alive', the precision of 88.55% for 'deceased', recall of 90.74% for 'deceased', training accuracy of 89.51%, AUC of 0.895, and testing accuracy of 87.80%, placing it in the category of good classification.
Although this research is limited to medical records and behavioral risk factors of heart failure patients to classify patient survival resilience, it addressed data imbalance, employed feature selection, and compared multiple algorithms to provide insights into their effectiveness for this specific classification task and improve model efficiency.

Regional variation in high vowel deletion in New Brunswick French: Preliminary observations
Authors: Cichocki Wladyslaw
Published: August 2024

This paper presents findings of a descriptive study that suggest that the deletion of high vowels, a process that is generally associated with Laurentian French, may have begun to spread across francophone regions of New Brunswick. The study examines the pronunciation of /t, d/ + /i, y/ sequences in a small number of lexical items, with a focus on vowel deletion. Based on acoustic phonetic analyses of sentences read by 136 speakers from the five main French-speaking regions in New Brunswick, results indicate that /i, y/ deletion rates are relatively high in the NorthWest, a region that is located adjacent to Quebec, but lower in other regions, with the lowest rates occurring in the SouthEast. Deletion rates are significantly higher among younger speakers than older speakers, indicating that this may be a sound change in progress. The results highlight an interaction between high vowel deletion and /t, d/ affrication. These preliminary observations provide guidelines for future dialectological and phonetic research on this process.
Perspectives intergénérationnelles de l’emprunt à l’anglais chez les francophones du Nord-Est ontarien
Authors: Boissonneault Julie
Published: August 2024

Dans un article paru en 2013, Alain Thomas faisait état de la perception qu’avaient des francophones du Nord-Est ontarien de l’utilisation des emprunts lexicaux à l’anglais. Ses résultats révèlent des différences intergénérationnelles, ce qui corrobore les tendances observées dans d’autres enquêtes auprès des francophones ontariens. Le glissement vers l’anglais n’est cependant pas régulier et l’anglicisation semble plus intense chez les locuteurs nés entre 1940 et 1960. Dans sa conclusion, Thomas exprimait le souhait que son enquête soit reproduite à plus grande échelle et que l’effet de la concentration des francophones dans les communautés soit vérifié. Ce texte y donne suite par une analyse de corpus auprès de 120 francophones nés entre le 19e et le 21e siècle et habitant diverses communautés du Nord-Est ontarien. L’analyse, qui s’inscrit dans une approche de synchronie dynamique, vise d’abord à dégager la présence de lexèmes empruntés à l’anglais en fonction des années de naissance des locuteurs, puis à comparer les probabilités d’usage des emprunts à celles des variantes françaises équivalentes. Puisque les communautés à l’étude varient de franco-minoritaires à franco-majoritaires, les indices d’usage sont ensuite vérifiés afin de cerner l’importance de cette variable dans le processus d’anglicisation.
Rythme prosodique dans le français et l’anglais des francophones du Nord-Est de l’Ontario
Authors: Tennant Jeff , Holmes Damaris
Published: August 2024

Cet article présente les résultats d’une étude du rythme prosodique du français et de l’anglais de Franco-Ontariennes et Franco-Ontariens de deux municipalités situées dans le Nord-Est de la province, Kapuskasing (francophones en situation locale majoritaire) et Timmins (francophones en situation locale minoritaire). Les données ne montrent pas une rythmicité plus accentuelle dans le contexte minoritaire de Timmins par rapport au contexte majoritaire de Kapuskasing. Ainsi, nos résultats ne soutiennent pas l’hypothèse d’une influence de l’anglais là où le contact du français avec cette langue est plus intense. En outre, les valeurs des mesures rythmiques révèlent que les francophones maintiennent une différence claire entre la rythmicité plutôt syllabique de leur français et la rythmicité plutôt accentuelle de leur anglais, résultat qui n’appuie pas l’hypothèse d’une convergence dans le rythme des deux langues en contact.

Published: August 2024

Muhammadiyah proactively seeks to involve all segments of society in various educational and social activities. This approach not only strengthens the basis of tolerance and understanding between religious communities but also helps reduce prejudice and promote peaceful coexistence. Education is one of the most effective tools used by Muhammadiyah to spread the values ​​of tolerance. Schools and universities founded by this organization offer curricula that emphasize the importance of social harmony and diversity. This education is not limited to academic knowledge alone, but also involves extracurricular activities that promote interaction between students from various religious and ethnic backgrounds. The success of this approach can be seen not only from the harmony maintained between religious communities within Muhammadiyah but also from the recognition and appreciation received from the wider community. This proves that religion can be a positive force in a pluralistic society, supporting the idea that tolerance and harmony are the main pillars in building and maintaining a society.

CONVERGENCE OF POPULATION AGEING: A NEW APPROACH
Authors: Ertürk Seda , Koç Selçuk
Published: August 2024

Beta and sigma convergence methods are generally used in convergence studies on the aging populations of countries. These methods give the result that countries with aging populations converge homogeneously. However, although the world population is aging, the aging rates and aging characteristics of countries will be different from each other due to the unique population compositions of each country and the policies they implement. Beta and sigma convergence analyses do not take into account heterogeneity in countries with aging populations. This study proposes a new approach that recognizes that countries have different aging characteristics. Our new approach illustrates the different aging characteristics of aging or aging countries by demonstrating the importance of the arithmetic mean. We compared the results of our analysis with the most common sigma convergence analysis in the literature. In this context, unlike the sigma convergence studies, we have revealed that there can be 5 different types of convergence when we separate countries according to income groups. The arithmetic mean convergence method we propose reveals the heterogeneity in the aging populations of countries, while also revealing the dynamics of convergence, and it has been concluded that the arithmetic mean method provides more effective and comprehensive information.
Long-Term Permissible Load Currents of Single-Core Cables with a Voltage of 10 kV with Cross-Linked Polyethylene Insulation of Various Designs
Authors: Vysotski M. E.
Published: August 2024

There is a large number of factors that affect the long-term permissible load currents of power cables, including environmental conditions, the method of laying, as well as the geometric, thermal and electrical characteristics of the cable structure. The catalogs of manufacturers of power cables with cross-linked polyethylene insulation do not specify the long-term permissible load currents, which would take into account the cross-sectional area of the screen, the presence of aluminum polymer tape and armor made of aluminum wires. These components can have a significant impact on the permissible load due to the currents induced in them during two-way grounding, which leads to additional heating of the cable. The purpose of this study is to analyze the influence of the above-mentioned factors on the long-term permissible load currents. The paper presents formulas for calculating the long-term permissible load current, which take into account the design features of the cables under consideration. The calculations have shown that the permissible load can decrease by 6 % with an increase in the cross-sectional area of the screen from the nominal row by one step. The introduction of an aluminum polymer tape into the cable structure changes the permissible load by no more than 2 %. The presence of armor can lead to a decrease in the permissible load by up to 18 % and its increase by up to 13 %, depending on the section of the core and screen, the method and conditions of laying. The calculation results obtained differ from the catalogdata by up to 25%. While the obtained errorsindicatetheneed to formcoefficientsfor a moreaccuratedetermination of the long-term permissible cable currents.
Rare-metal-free broadband near-infrared phosphors
Authors: Xiao Wenge , Zheng Guojun , Lou Chenjie , Zhong Jiyou , Tang Mingxue , Qiu Jianrong
Published: August 2024

Phosphors are the key enabling components for down-converted light emitting diodes (LEDs) which are regarded as the most efficient, cheapest and smallest broadband light sources1,2.Although myriad phosphors have been developed3–8, very few finally come into practical use in consideration of efficiency, stability and price. Unlike visible phosphors, broadband near-infrared (NIR) phosphors rarely achieved high efficiency and high stability9–13, and furthermore, they usually contain high content of rare-metal elements14–18, thus precluding NIR applications of phosphor-converted LEDs (pc-LEDs). Here, we report such a class of broadband NIR phosphors that possesses excellent luminescence properties while is free of rare-metal elements, by revealing weak-field octahedral sites for Cr3+ occupation in MgAl2O4 spinel that is conventionally believed to only offer strong-field octahedral sites. Such weak-field octahedral sites are attributed to the intrinsic cation inversion in the spinel structure, and can be finely engineered by superstoichiometric Al2O3. We further introduce SiO2 to break the inversion symmetry of octahedral sites for boosting the 3d–3d transition probabilities and thus the photoexcitation efficiency. The corresponding pc-LED prototype delivers bright and stable broadband NIR light with an optical power of 180.8 mW and a photoelectric efficiency of 16.0% at the rated current, more than two times those of the commercialized and reported counterparts, meaning a big step forward for broadband light sources.

Depositing Al-Zn-Mg-Cu alloy with different positive electrode/negative electrode ratios of CMT advance process
Authors: Wu Xiangyang , Xu Shanqing , Chen Ji , Wu Chuansong
Published: August 2024

To explore the influence of electrode positive/electrode negative (EP/EN) ratio on CMT advance-based wire arc additive manufacturing (WAAM) process for Al-Zn-Mg-Cu alloy, the behaviors of deposition process, the microstructure and mechanical properties of Al-Zn-Mg-Cu alloy WAAM are studied. The results showed that electrical waveforms and arc/metal transfer were unstable with a low EP/EN ratio, which deteriorated the stability of WAAM. The forming accuracy of deposited samples firstly increased with the EP/EN ratio ranging from 4:16 to 13:7, and then decreased if the EP/EN ratio continued increasing. In the inter-layer region, the samples showed a combination of columnar grains and pony-size equiaxed grains with an EP/EN ratio ranging from 4:16 to 10:10, while the size and quantity of equiaxed grains increased and the columnar grains almost disappeared with a higher EP/EN ratio (≥ 13:7). The enriched alloy elements in the grain boundary were easy to form large-scale precipitated phases, which were harmful to the mechanical properties. The microhardness distribution of all samples had the apparent fluctuation along the building direction due to the existence of the microstructure evolution and pores defect. This study proved that CMT advance process was a practicable and effective way for WAAM of Al-Zn-Mg-Cu alloy with optimal EP/EN ratio.

Authors: Ma Wei , Wu Xiaoxiao , Zhang Qing , Li Xiang , Wu Xinglong , Wang Jun
Published: August 2024

Thyroid cancer is the most common malignancy in the endocrine system, with a rising incidence worldwide in recent decades. Traditional Central Processing Unit (CPU) and Graphics Processing Unit (GPU) software face limitations in processing speed, efficiency, and power consumption, necessitating more efficient solutions. This study proposes a Field-Programmable Gate Array (FPGA)-accelerated quantized inference method to improve the efficiency and accuracy of thyroid nodule detection. We selected YOLOv4-tiny as the neural network model, incorporating Kmeans + + for optimal anchor box dimensions at the software level and combining 8-bit weight quantization with batch normalization and convolution layer fusion at the hardware level to reduce computational complexity. Additionally, a double buffering mechanism and pipelined design were employed to enhance parallelism and hardware resource utilization. We conducted tests on an internal dataset from a tertiary hospital in China. The experimental results show that our proposed FPGA-accelerated ultrasound thyroid nodule detection system performs excellently in terms of image recognition accuracy, speed, and power consumption. The average accuracy is 81.44% on the Tn3k dataset and 81.20% on the internal test dataset, with each image taking 0.398 seconds to process and consuming 3.119 watts of power. The energy efficiency is 17.6 times that of the Intel Core i5-10200H and 0.98 times that of the GeForce RTX 4090. This study offers a new technological pathway for medical imaging diagnosis, potentially enhancing the speed and accuracy of ultrasound image analysis, thereby improving physician efficiency and diagnostic capabilities.

Authors: Heng Chun-Ni , Du Juan , Li Ling , Zhang Na , Jiang Wei
Published: August 2024

Introduction: The outbreak of Corona Virus Disease (COVID-19) in 2019 has continued until now, posing a huge threat to the public’s physical and mental health, resulting in different degrees of mental health problems. Previous studies have shown that insomnia is one of the main influences on anxiety. However, due to the specificity of the disease and the situation of centralized treatment of COVID-19 patients in mobile cabin hospitals, insomnia interventions are limited. Therefore, it is necessary to find the complex mediating variables between insomnia and anxiety to provide new ideas for the prevention and intervention of anxiety caused by insomnia in COVID-19 patients. Methods: The measurement tools were the Athens Insomnia Scale, Psychological Capital Questionna- ire, and Self-Rating Anxiety Scale. Statistical analysis was performed using SPSS 25.0 software, and a mediator model was established and corrected using Amos software. Results: More than one in five patients in this study had anxiety, and the total score was significantly higher than the Chinese standard total score. Insomnia was positively correlated with anxiety, but negatively correlated with psychological capital; and psychological capital was negatively correlated with anxiety. Psychological capital can act as a mediating factor in the relationship between insomnia and anxiety. Psychological capital played a mediating role in the relationship between insomnia and anxiety among COVID-19 patients, that is, insomnia not only directly affected anxiety, but also indirectly affected anxiety through the mediating role of psychological capital. Conclusion: It is recommended that patients and health care professionals increase the psychological capital of COVID-19 patients through various methods to counter the effects of insomnia on anxiety.

Background
Sarcoidosis is a multisystem disease characterized by non-caseating granulomas, typically identified by peribronchovascular and perilymphatic nodules on high-resolution computed tomography (HRCT). Miliary sarcoidosis, an atypical presentation involving diffuse pulmonary infiltrates, is rarely reported, occurring in less than 1% of cases.
Case Presentation
We present a case of a 60-year-old Caucasian woman with unexplained weight loss, breathlessness, and cough. Initial chest CT revealed extensive hilar and mediastinal lymphadenopathy with diffuse pulmonary infiltrates, suggesting disseminated malignancy. However, subsequent PET-CT scans showed intense and widespread FDG avidity throughout the lungs and mediastinal nodes, indicative of miliary sarcoidosis. Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) confirmed non-caseating granulomas, leading to a diagnosis of sarcoidosis. The patient was treated with oral corticosteroids, resulting in significant clinical and radiological improvement.
Conclusion
This case underscores the importance of recognizing atypical imaging patterns in sarcoidosis, such as miliary distribution, to avoid misdiagnosis and ensure appropriate management. The combination of advanced imaging techniques and minimally invasive biopsy procedures is crucial for accurate diagnosis and effective treatment.

Background: To analyze a series of CT-detected masked otitis media in various clinical situations in order to remind attention to this possible pathogenesis that is easy to be overlooked.
Methods: This is Case series.Charts of patients referred for different otological complaints, including ear discomforts, vertigo or facial nerve abnormality, with an intact tympanic membrane were reviewed. Complete record of clinical history and otological examinations were required. Those with High-resolution CT (HRCT) finding of masked otitis media, which seemed to be response for the patients’ complaints, were included in the analysis.
Results: A total of 15 cases of CT-detected masked otitis media were included for analysis. There were 12 cases with conductive or mixed hearing loss, 11 of which were presented asopacifications or sclerosing plaques involving the ossicles in HRCT. There were 2 cases considered as complications of otitis media, including one case of vertigo and one case of facial paralysis. Opacificationswere found in the round window niche and around the facial nerve respectively in HRCT. The remaining case merely complained of earache in the retroauricular region with normal hearing results, whose HRCT revealed Opacifications in partial mastoid cells.
Conclusion: Masked otitis media as a possible pathogenesis in various clinical situations should be remind enough attention to. A detailed disease history and comprehensive analysis of otological tests, especially the careful reading of the temporal HRCT, could provide important clues for the discrimination of masked otitis media.

Background and objective: Hemoptysis is a life-threatening condition requiring urgent treatment. Bronchial artery embolization (BAE), established as the primary intervention, is an effective treatment for hemoptysis. Common etiologies include bronchiectasis, tumors, tuberculosis, aspergilloma, and cystic fibrosis. Approximately 20 % of hemoptysis cases are categorized as cryptogenic. We conducted a retrospective observational study to understand the clinical characteristics of patients with cryptogenic hemoptysis (CH).
Methods: The clinical characteristics, angiographic findings, and immediate and long-term efficacies of BAE were retrospectively analyzed in 36 consecutive patients between January 2010 and December 2022. Superselective BAE was successfully performed in all patients by using a gelatin sponge (GS).
Results: The median age was 68 years, and 21 patients (58.3 %) were male. Among them, 15 patients (41.7 %) presented with massive hemoptysis, and 7 (19.4%) required intubation. Angiographic evaluation revealed the treatment of total 57 vessels, comprising 51 (89.5%) bronchial arteries, 5 (8.8 %) intercostal arteries, and 1 (1.8 %) inferior transverse artery. The recurrence-free rates were 100 % at 1 month, 94.4 % at 3 months, 94.4 % at 12 months, and 86.1 % at more than 12 months. Only one patient required a second BAE for hemoptysis, while others were managed for recurrences with oral hemostatic agents. No serious complications, such as spinal cord infarction, were observed during the study period.
Conclusion: BAE treatment with GS for CH proved to be a suitable therapeutic modality, demonstrating high efficacy in halting bleeding in both the short and long terms, with the absence of severe complications, including spinal cord infarction.

Objetive: Observe the effect of a therapeutic exercise (TE) programme on physical capacity of patients undergoing haematopoietic stem cell transplant (HSCT) 3 months after intervention.
Patients and methods: An observational study was carried out in patients who underwent a HSCT at the Álvaro Cunqueiro Hospital in Vigo (Spain) between September 2020 and August 2021. Patients were assessed before admission and 3 months after the transplant. 30-second chair stand test (30”CST) was used to measure lower body resistance, and timed up and go (TUG) to assess functional mobility and detect balance and coordination problems. During admission, patients completed the TE programme developed at the hospital based on guidelines from the Spanish Group for Transplantation and Cellular Therapy (GETH-TC).
Results: 34 patients were included. Three months after HSCT, a decrease in number of 30”CST repetitions from 11.58±4.09 to 10.94±3.54 (p<0.0001) and in time to perform the TUG from 9.86±5.56 to 8.65±3.30 seconds (p<0.0001) was recorded. Fewer incidents which required help were recorded (from 21 to 16).
Conclusions: A TE programme in HSCT is safe, can improve coordination and balance, and serves to mitigate the loss of muscle strength these patients tend to experience because of disease, the transplant process, and prolonged inactivity.

Atherosclerosis is a growing concern in developed nations, necessitating the identification of therapeutic targets for advancing personalized medicine. Serum amyloid A3 (Saa3) has been linked to accelerated plaque progression by affecting cholesterol metabolism and modulation of inflammation. We hypothesize that knocking out Saa3 (Saa3-/-) could mitigate plaque development by regulating aortic immune cell subsets during atherosclerosis progression. Using a murine model, we induced atherosclerosis via a gain-of-function mutant PCSK9-encoding adeno-associated viral vector (AAVmPCSK9) in wild-type (WT) and Saa3-/- mice. Single-cell RNA sequencing revealed that Saa3-/- mice developed smaller plaques than WT mice, with significant differences in aortic immune cell populations, particularly aortic macrophages. Saa3-/- macrophages, characterized by high Gpnmb, Lpl, and Spp1 expressions, predominated over the typical resident foamy macrophages in WT mice. Saa3-/- mice also showed enhanced intercellular immune communication and increased signaling interactions, suggesting a shift towards an anti-inflammatory and tissue-repairing phenotype. Our study highlights the potential of Saa3 as a therapeutic target for atherosclerosis.
