Analisis Perbandingan Algoritma Dijkstra dan A-Star dalam Menentukan Rute Terpendek
Authors: Pratama Jordi Yoga 
Published: November 2024

Some applications, such as Google Maps, require an effective algorithm, to determine the shortest route. The two most commonly used algorithms to solve this problem are the Djikstra and A-Star algorithms. The Djikstra algorithm is famous for its accuracy in finding the shortest route by exploring all possible routes, but it has the disadvantage of long computation times on large graphs. The A-Star algorithm, on the other hand, uses heuristics to guide searches to destinations faster, reduce the number of nodes explored, and speed up computational time. The study analyzed the comparison of the two algorithms using Python in Colab. The focus of the research is the computing time and the smallest route accuracy produced. The results showed that both algorithms had the same ability to find the shortest route, but A-Star was more efficient in computing time. Recommendations are given for the use of each algorithm based on graph size and priority of computing needs. This research is expected to provide insight for application developers in choosing the algorithm that best suits their needs.
Single-cell data revealed the function of natural killer cells and macrophage cells in chemotherapy tolerance in acute myeloid leukemia
Authors: Gao Jing , Yan Xueqian , Fan Dan , Li Yuanchun 
Published: November 2024

Background
Acute myeloid leukemia (AML) is highly prevalent and heterogeneous among adult acute leukemias. Current chemotherapeutic approaches for AML often face the challenge of drug resistance, and AML immune cells play an important role in the regulation of AML drug resistance. Thus, it is of key significance to explore the regulatory mechanisms of immune cells in AML to alleviate chemotherapy resistance in AML.

Methods
Based on AML single-cell transcriptomic data, this study revealed the differences in the expression of immune cell subpopulations and marker genes in AML patients in the complete remission group (CR) compared to AML patients in the non-complete remission group (non-CR) after chemotherapy. Functional enrichment by clusterprofiler revealed the regulatory functions of differentially expressed genes (DEGs) in AML. AUCell enrichment scores were used to assess the immunoregulatory functions of immune cells. Pseudotime analysis was used to construct immune cell differentiation trajectories. CellChat was used for cellular communication analysis to elucidate the interactions between immune cells. Survival analysis with the R package “survival” revealed the role of immune cell marker genes on AML prognosis. Finally, the wound healing and trans-well assay were performed.

Results
Single-cell clustering analysis revealed that NK/T cells and macrophage cells subpopulations were significantly higher in non-CR AML patients than in CR AML. AUCell enrichment analysis revealed that FCAR+ and FCGR3A+ macrophages were significantly more active in the non-CR group and correlated with processes regulating cellular energy metabolism and immune cell activity. Differentially expressed NK cell marker genes between CR and non-CR groups mainly included HBA1, S100A8, and S100A9, which were associated with cancer drug resistance regulation, these marker genes of (FCAR, FCGR3A, PREX1, S100A8 and S100A9) were upregulated in human chronic myeloid leukemia cells (HAP1) and silencing of S100A8 affected migration and invasion of HAP1 cells. In particular, the differentiation pathways of macrophages and NK cells in non-CR differed from those of patients in the CR group. Cellular communication analyses showed that ligand-receptor pairs between NK cells and macrophage cells mainly included HLA-E-KLRK1, HLA-E-KLRC1, HLA-E-CD94:NKG2A, CLEC2B-KLRB1. In addition, LGALS9-CD45, CCL3L1- CCR1, CCL3-CCR1 between these two immune cells mainly regulate secreted signaling to mediate AML progression. Marker genes in NK/T cells and macrophage cells were significantly associated with AML prognosis.

Conclusion
This study reveals the potential role of NK cells and macrophages in AML chemoresistance through the analysis of single-cell RNA sequencing data. This provides new ideas and insights into the key mechanisms of immune cells in AML treatment.
The ecological niche characteristics and interspecific associations of plant species in the alpine meadow of the Tibetan Plateau affected plant species diversity under nitrogen addition
Authors: Xiang Xuemei , De Ke Jia , Lin Weishan , Feng Tingxu , Li Fei , Wei Xijie 
Published: November 2024

Background
Plant species diversity is of great significance to maintain the structure and function of the grassland ecosystem. Analyzing community niche and interspecific associations is crucial for understanding changes in plant species diversity. However, there are few studies on the response of plant species diversity, species niche characteristics, and interspecific relationships to nitrogen addition in alpine meadows on the Qinghai-Tibet Plateau.

Methods
This study investigates the effects of different levels of nitrogen addition (0, 15, 30, 45, and 60 g N m−2) on plant species diversity, functional group importance values, niche width, niche overlap, and interspecific associations in an alpine meadow.

Results
1) Compared with the control (CK), the Shannon-Weiner index and species richness index significantly increased by 11.36% and 30.77%, respectively, with nitrogen addition at 30 g N m−2, while both indices significantly decreased by 14.48% and 23.08%, respectively, at 60 g N m−2. As nitrogen addition increased, the importance value of grasses showed an upward trend, whereas the importance value of sedges showed a decline. 2) The niche width of Poa pratensis L., Elymus nutans Griseb., and Stipa purpurea Griseb. are increased with higher nitrogen addition. As nitrogen addition increases, the niche overlap values also show a rising trend. At 60 g N m−2, the overall community association in the alpine meadow exhibited a significant negative correlation. These findings suggest that grasses exhibit strong ecological adaptability under high nitrogen addition and gain a competitive advantage in spatial competition, increasing their niche width. Moreover, as nitrogen levels increase, the importance values of grasses rise significantly, and their ecological characteristics become more similar, resulting in reduced niche overlap among plant species. Furthermore, high nitrogen addition intensifies interspecific competition between grasses, sedges, and forbs, disrupting the original balance and reducing species diversity. These insights provide a valuable understanding of changes in species diversity and competitive dynamics in alpine meadow plant communities under high nitrogen addition.
Health-related quality of life and its associated factors among Chinese seasonal retired migrants in Hainan

Published: November 2024

Background
Seasonal retired migrants are mainly retired or semiretired people who migrate to warmer areas during the winter and then return to their original homes in the following year. Despite its increasing popularity, the evidence concerning the health status of Chinese seasonal retired migrants is controversial. Although some studies have shown that seasonal retired migrants have better health status, other studies note that migrants are driven involuntarily by health concerns and that their mental health suffers during migration. The objective of this study was to provide quantified evidence on the health-related quality of life (HRQoL) of seasonal retired migrants in China and to identify potential factors associated with HRQoL.

Methods
This was a community-based cross-sectional study of seasonal retired migrants who lived in Wuzhishan, Hainan during the winter. The Chinese version of the EuroQol 5-Dimension 5-Level (EQ-5D-5L) was used to assess participants’ HRQoL. Data on demographic and behavioral characteristics, body mass index, and the presence of chronic diseases were collected using a self-administered survey. Logistic regressions were used to explore the factors associated with responses in each dimension of the EQ-5D-5L descriptive system, and a multiple linear regression model was used to explore the factors associated with EuroQol visual analogue scale (EQ-VAS) scores.

Results
A total of 992 participants (female: 56.5%) were enrolled in the current study, with a mean age of 67.87 ± 6.98 years. Most participants reported problems in the pain/discomfort dimension (16.7%), followed by the anxiety/depression dimension (8.3%). Few participants reported problems in the first three dimensions of the EQ-5D-5L: mobility (5.4%), usual activities (2.0%), and self-care (1.2%). The median EQ-VAS score was 84 (interquartile range: 80–89). The regression results indicated that poor sleep quality, the presence of chronic diseases, and low-level physical activity were important factors that were negatively associated with multiple dimensions of the EQ-5D-5L. In addition, the EQ-VAS score was negatively associated with age, the presence of chronic diseases, poor sleep quality, and low-level physical activity.

Conclusion
This study revealed that Chinese seasonal retired migrants have high HRQoL. In addition, this study revealed that sleep quality and physical activity are correlated with multiple dimensions of the EQ-5D-5L descriptive system and EQ-VAS. Therefore, lifestyle interventions related to sleep quality and physical activity are essential for improving HRQoL among Chinese seasonal retired migrants.

The emergence of new antibiotic‐resistant bacterial strains means it is increasingly important to find alternatives to traditional antibiotics, such as bacteriolytic enzymes. The bacteriolytic enzyme lysozyme is widely used in medicine as an antimicrobial agent, and covalent immobilization of lysozyme can expand its range of possible applications. However, information on the effect of such immobilized preparations on whole bacterial cells is quite limited. Here, we demonstrate the differential effects of glycine and charged (basic and acidic) amino acids on the enzymatic lysis of Gram‐positive and Gram‐negative bacteria by soluble and immobilized lysozyme. Glycine and basic amino acids (histidine, lysine, and arginine) significantly increase the rate of lysis of Gram‐negative Escherichia coli cells in the presence of soluble lysozyme, but they do not substantially affect the rate of enzymatic lysis of Gram‐positive Micrococcus luteus. Glutamate and aspartate significantly enhance enzymatic lysis of both E. coli and M. luteus. When using immobilized lysozyme, the effects of amino acids on the rate of cell lysis are significantly reduced. For immobilized lysozyme, the presence of an external diffusion mode on cell lysis kinetics at bacterial concentrations below 4 × 108 colony‐forming units·mL−1 was shown. The broadening of the pH optimum of lysozyme activity after immobilization has been demonstrated for both Gram‐positive and Gram‐negative bacteria. The Michaelis constant (Km) values of immobilized lysozyme were increased by 1.5‐fold for E. coli cell lysis and 4.6‐fold for M. luteus cell lysis compared to soluble enzyme. A greater understanding of the effect of amino acids on the activity of native and immobilized lysozyme is important for both the development of new materials for medical purposes and elucidating the interaction of lysozyme with bacterial cells. Of particular interest is our finding that lysozyme activity against Gram‐negative bacteria is enhanced in the presence of glycine and charged amino acids over a wide range of concentrations.

Published: January 2019

AbstractIn the present paper, the influence of Tunisian clay filler on rheological and thermal behaviors of based recycled polypropylene (RPP) composites is investigated. RPP was mixed with 1, 3, 5, and 7 wt% of Tunisian clay particles using twin‐screw extruder. Maleic anhydride‐grafted polypropylene (PP‐g‐MA) was used as a compatibilizer. The morphological, structural, rheological, and thermal properties of raw and composite materials were analyzed. Scanning electron microscopy results showed that with the incorporation of clay and PP‐g‐MA, the particles were uniformly dispersed into RPP/PP‐g‐MA/clay composites. FTIR analysis showed that clay particles altered the shape of the observation band of RPP, indicating the presence of a chemical interaction between the clay and RPP matrix. The increased storage and loss moduli indicated that the Tunisian clay had a reinforcing effect on the RPP matrix. In differential scanning calorimetry analysis, crystallization temperature (Tc) increased with clay content, indicating that the addition of Tunisian organoclay accelerated the crystallization of the RPP matrix. The slight decrease in melting temperature (Tm) with increasing clay loading could be due to PP‐g‐MA, which affects the mobility of macromolecular chains.

Authors: Jiang Ying , Yu Xiaoxiao , Yu Ruobing 
Published: January 2019

AbstractA novel phenolic resin (phenolic containing diphenyl oxide [named byMPF]) was synthesized and blended with poly(ethylene oxide) (PEO). In modifiedPEO, the shear‐thinning behavior appears and shortage modulus (G′) deviates from classic terminal behavior. Compared withPEO, there is an increase in the nucleation rate and a decrease in the growth rate of spherulites in modifiedPEO. A small amount ofMPFplays a role of the nucleating agent ofPEO. The addition ofMPFintoPEOmakes the glass transition temperature (Tg) and thermal decomposition temperature (Td5%) ofPEOhigher. When the content ofMPFis 2%, theTd5%ofMPF/PEOis 346°C, which is much higher than that of purePEO(240°C). When the content ofMPFis 50%,TgofPEOis up to 26°C, which is 90°C higher than that of purePEO.
