| ○ | ○ | Article | The Relationship and Effects of Self-Esteem and Body Shape on Eating Disorder Behavior: A Cross-Sectional Survey of Chinese University Students | Background: Eating disorders (EDs) have become a global public health concern among adolescents and young adults. However, Chinese university students exhibit a high prevalence of eating disorders. This study aims to investigate the effects of self-esteem (SE) and body shape (BS) on ED behaviors among Chinese university students. Methods: Using random sampling, 946 Chinese university students (aged 18 to 24, M = 19.94, SD = 1.04) participated in a survey comprising the Sick, Control, One, Fat, and Food Questionnaire (SCOFF-Q), the Body Shape Questionnaire (BS-Q), and the Rosenberg Self-Esteem Scale (RS-S) to assess their eating disorder or non-eating disorder (NED) behavior. Results: There was a significant positive correlation between body shape and eating disorder behaviors (r = 0.19, p < 0.01), while there was a significant negative correlation between self-esteem and eating disorder behaviors (r = -0.14, p = 0.001 < 0.01). Gender was a moderating factor in the relationship between body shape and eating disorder behaviors (t = 3.14, p = 0.002 < 0.01), while parents' marital status was a moderating factor in the relationship between self-esteem and eating disorder behavior (t = 2.72, p = 0.007 < 0.01). Body shape (z = 6.47, p = 0.001 < 0.01), self-esteem (z = -2.81, p = 0.005 < 0.05), and gender (z = 3.06, p = 0.002 < 0.01) significantly influenced eating disorder behavior among Chinese university students aged 18-24 years. Conclusions: There was a direct effect between body shape and self-esteem and eating disorder behaviors among Chinese university students aged 18-24 years. Alarmingly, female university students are becoming susceptible to external influences on self-esteem and body shape, leading to eating disorder behaviors at an increasingly younger age in China. | Gao, Zeng; Zhao, Jingyi; Peng, Sanying; Yuan, Han | Univ Sains Malaysia, Sch Educ Studies, George Town 11800, Malaysia; Nanjing Inst Technol, Phys Educ Dept, Nanjing 211167, Peoples R China; Hohai Univ, Phys Educ Dept, Nanjing 211100, Peoples R China; Kyungpook Natl Univ, Dept Phys Educ, Daegu 41566, South Korea | ; Zhao, Jing-yi/K-3480-2012; Yuan, Han/LUY-3102-2024; Peng, Sanying/ISB-0162-2023 | 59141458400; 57219712840; 56539142300; 58784951600 | 2021327546@knu.ac.kr; | HEALTHCARE | HEALTHCARE-BASEL | 2227-9032 | 12 | 10 | SCIE;SSCI | HEALTH CARE SCIENCES & SERVICES;HEALTH POLICY & SERVICES | 2024 | 2.7 | 27.8 | 4.48 | 2025-05-07 | 7 | 7 | somatotypes; self-perception; feeding and eating disorders; Chinese university students | SCOFF QUESTIONNAIRE; PREVALENCE; RISK; WEIGHT; PATHOLOGY; MODEL | Chinese university students; feeding and eating disorders; self-perception; somatotypes | English | 2024 | 2024-05 | 10.3390/healthcare12101034 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Aging-Induced Changes in Cutibacterium acnes and Their Effects on Skin Elasticity and Wrinkle Formation | Skin aging involves biomechanical changes like decreased elasticity, increased wrinkle formation, and altered barrier function. The skin microbiome significantly impacts this process. Here, we investigated the effects of decreased Cutibacterium acnes abundance and increase in other skin microorganisms on skin biomechanical properties in 60 healthy Koreans from Seoul, divided into younger (20-29 years) and older (60-75 years) groups. Metagenomic sequencing and skin assessments showed that the older group exhibited decreased C. acnes dominance and increased microbial diversity, correlating with reduced skin elasticity and increased wrinkles. In the younger age group, the enriched pathways included zeatin biosynthesis, distinct biotin metabolism pathways, and cofactor and vitamin metabolism in the younger age group, whereas pathways related to lipid metabolism, energy metabolism, and responses to environmental stressors, including UV damage and pollution, were enriched in the older group, according to functional analysis results. Network analysis indicated higher microbial connectivity in the younger group, suggesting a more stable community, whereas the older group's community displayed higher modularity, indicating more independent and specialized clusters. This study enhances our understanding of the impact of skin microbiome changes on skin aging, particularly the anti-aging effects of C. acnes. Future research should focus on the physiological mechanisms of skin microbiota on skin aging and explore therapeutic potentials to enhance skin health. | Jung, Yeongyun; Kim, Ikwhan; Jung, Da-Ryung; Ha, Ji Hoon; Lee, Eun Kyung; Kim, Jin Mo; Kim, Jin Young; Jang, Jun-Hwan; Bae, Jun-Tae; Shin, Jae-Ho; Cho, Yoon Soo | Hallym Univ, Hangang Sacred Heart Hosp, Coll Med, Burn Inst, Seoul 07247, South Korea; Kyungpook Natl Univ, Dept Integrat Biol, Daegu 41566, South Korea; Kolmar Korea, R&D Ctr, Seoul 06800, South Korea; Hallym Univ, Hangang Sacred Heart Hosp, Coll Med, Dept Rehabil Med, Seoul 07247, South Korea; J2KBIO, Chungbuk 28104, South Korea; Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Kyungpook Natl Univ, KNU NGS Core Facil, Daegu 41566, South Korea | ; Cho, Yoon Soo/JXL-2899-2024; Lee, Eunkyung/AAG-1192-2019; shin, Jaeho/K-6792-2013 | 57197833801; 58643019600; 57221116102; 58626062200; 57230063400; 59403513100; 59403558900; 59403559000; 58175572800; 57224125922; 56059636900 | jyg1076@gmail.com;ikwhankim0926@gmail.com;amugae1210@knu.ac.kr;jh_cos@kolmar.co.kr;eunlee0617@gmail.com;kimjinmo@kolmar.co.kr;jinyoung_cos@kolmar.co.kr;jjh1117@j2kbio.com;jtbae@j2kbio.com;jhshin@knu.ac.kr;yschorm@hallym.ac.kr; | MICROORGANISMS | MICROORGANISMS | 2076-2607 | 12 | 11 | SCIE | MICROBIOLOGY | 2024 | 4.2 | 27.9 | 0.6 | 2025-05-07 | 1 | 1 | skin aging; skin microbiome; biomechanical properties; metagenomic sequencing; microbial diversity | MICROBIOME | biomechanical properties; metagenomic sequencing; microbial diversity; skin aging; skin microbiome | English | 2024 | 2024-11 | 10.3390/microorganisms12112179 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Antioxidant and Antimelanogenic Activities of Lactobacillus kunkeei NCHBL-003 Isolated from Honeybees | Excessive reactive oxygen species production can detrimentally impact skin cell physiology, resulting in cell growth arrest, melanogenesis, and aging. Recent clinical studies have found that lactic acid bacteria have a special effect directly or indirectly on skin organs, but the exact mechanism has not been elucidated. In this study, we investigated the mechanisms underlying the antioxidant protective effect and the inhibitory effect on melanin synthesis of Lactobacillus kunkeei culture supernatant (CSK), isolated from Apis mellifera Linnaeus (the Western honeybee). CSK exhibited notable efficacy in promoting cell migration and wound healing under oxidative stress, surpassing the performance of other strains. CSK pretreatment significantly upregulated the expression of Nrf2/HO-1 (nuclear factor erythroid 2-related factor 2/heme oxygenase-1), a key player in cellular defenses against oxidative stress, relative to the control H2O2-treated cells. The DCF-DA (dichloro-dihydro-fluorescein diacetate) assay results confirmed that CSK's ability to enhance Nrf2 and HO-1 expression aligns with its robust ability to remove H2O2-induced reactive oxygen species. Furthermore, CSK upregulated MAPK (mitogen-activated protein kinase) phosphorylation, an upstream signal for HO-1 expression, and MAPK inhibitors compromised the wound-healing effect of CSK. Additionally, CSK exhibited inhibitory effects on melanin synthesis, downregulating melanogenesis-related genes in B16F10 cells. Thus, the present study demonstrated that CSK exhibited antioxidant effects by activating the Nrf2/HO-1 pathway through MAPK phosphorylation, thereby restoring cell migration and demonstrating inhibitory effects on melanin production. These findings emphasize the antioxidant and antimelanogenic potential of CSK, suggesting its potential use as a therapeutic agent, promoting wound healing, and as an active ingredient in skin-lightening cosmetics. | Lee, Yeon-Ji; Choi, Joo-Hee; Kang, Kyung-Ku; Sung, Soo-Eun; Lee, Sijoon; Sung, Minkyoung; Seo, Min-Soo; Park, Jong-Hwan | Daegu Gyeongbuk Med Innovat Fdn, Preclin Res Ctr, Daegu 41061, South Korea; Kyungpook Natl Univ, Coll Vet Med, Lab Vet Tissue Engn, 80 Daehak Ro, Daegu 41566, South Korea; Chonnam Natl Univ, Coll Vet Med, Lab Anim Med, 77 Yongbong Ro, Gwangju 61186, South Korea; Chonnam Natl Univ, Brain Korea 21 PLUS Project Team, 77 Yongbong Ro, Gwangju 61186, South Korea | Lee, Sijoon/LIC-1291-2024 | 57216743538; 55882556800; 57215079376; 56051194000; 57219164019; 57256838000; 35254332100; 15838687800 | wudsl0000@kmedihub.re.kr;cjh522@kmedihub.re.kr;kangkk@kmedihub.re.kr;sesung@kmedihub.re.kr;sjlee1013@kmedihub.re.kr;tjdalsrud27@kmedihub.re.kr;msseo@knu.ac.kr;jonpark@jnu.ac.kr; | MICROORGANISMS | MICROORGANISMS | 2076-2607 | 12 | 1 | SCIE | MICROBIOLOGY | 2024 | 4.2 | 27.9 | 2.02 | 2025-04-16 | 3 | 3 | Lactobacillus kunkeei NCHBL-003; honeybee microbiome; postbiotic supernatants; antioxidant; antimelanogenic | OXIDATIVE STRESS; SIGNALING PATHWAY; HYDROGEN-PEROXIDE; MELANIN BIOSYNTHESIS; HEME OXYGENASE-1; GENE-EXPRESSION; PROTEIN; MELANOCYTE; TRANSCRIPTION; ACIDOPHILUS | antimelanogenic; antioxidant; honeybee microbiome; Lactobacillus kunkeei NCHBL-003; postbiotic supernatants | English | 2024 | 2024-01 | 10.3390/microorganisms12010188 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Comparative Analysis of Gut Microbiota between Captive and Wild Long-Tailed Gorals for Ex Situ Conservation | The long-tailed goral is close to extinction, and ex situ conservation is essential to prevent this phenomenon. Studies on the gut microbiome of the long-tailed goral are important for understanding the ecology of this species. We amplified DNA from the 16S rRNA regions and compared the microbiomes of wild long-tailed gorals and two types of captive long-tailed gorals. Our findings revealed that the gut microbiome diversity of wild long-tailed gorals is greatly reduced when they are reared in captivity. A comparison of the two types of captive long-tailed gorals confirmed that animals with a more diverse diet exhibit greater gut microbiome diversity. Redundancy analysis confirmed that wild long-tailed gorals are distributed throughout the highlands, midlands, and lowlands. For the first time, it was revealed that the long-tailed goral are divided into three groups depending on the height of their habitat, and that the gut bacterial community changes significantly when long-tailed gorals are raised through ex situ conservation. This provides for the first time a perspective on the diversity of food plants associated with mountain height that will be available to long-tailed goral in the future. | Park, Chang-Eon; Jo, Young-Jae; Jung, Da-Ryung; Park, Hee-Cheon; Shin, Jae-Ho | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Minist Environm, Ex Situ Conservat Inst, Inst Ornithol, Gumi 39105, South Korea; Kyungpook Natl Univ, NGS Core Facil, Daegu 41566, South Korea | Park, Chang Eon/ACL-1997-2022 | 57213511897; 57214743390; 57221116102; 56779256600; 57224125922 | aeonrapt@knu.ac.kr;dudwo7573@knu.ac.kr;amugae1210@knu.ac.kr;cranesave@naver.com;jhshin@knu.ac.kr; | MICROORGANISMS | MICROORGANISMS | 2076-2607 | 12 | 7 | SCIE | MICROBIOLOGY | 2024 | 4.2 | 27.9 | 0 | 2025-05-07 | 1 | 1 | conservation biology; ex situ conservation; long-tailed goral; gut microbiome | SP NOV.; GEN.

| ○ | ○ | Article | Comparative Analysis of Hindgut Microbiota Variation in Protaetia brevitarsis Larvae across Diverse Farms | Protaetia brevitarsis larvae are farm-raised for food, are used in traditional East Asian medicine, and convert organic waste into biofertilizers. Here, the comparative analysis of the gut microbiota of third-instar larvae obtained from five different farms was investigated using 16S rRNA microbial profiling. Species richness, evenness, and diversity results using alpha-diversity analysis (observed species, Chao1, Shannon, Simpson) were similar between farms, except for those between the TO and KO farms. beta-diversity was significantly different in distribution and relative abundance between farms (PERMANOVA, pseudo-F = 13.20, p = 0.001). At the phylum level, Bacillota, Bacteroidota, Actinomycetota, and Pseudomonadota were the most dominant, accounting for 73-88% of the hindgut microbial community. At the genus level, Tuberibacillus, Proteiniphilum, Desulfovibrio, Luoshenia, and Thermoactinomyces were the most abundant. Although oak sawdust was the main feed component, there were large variations in distribution and relative abundance across farms at the phylum and genus levels. Venn diagram and linear discriminant analysis effect size analyses revealed large variations in the hindgut microbial communities of P. brevitarsis larvae between farms. These results suggest environmental factors were more important than feed ingredients or genetic predisposition for the establishment of the intestinal microbiota of P. brevitarsis larvae. These findings serve as reference data to understand the intestinal microbiota of P. brevitarsis larvae. | Min, Namkyong; Min, Jean Geung; Cammayo-Fletcher, Paula Leona T.; Nguyen, Binh T.; Yim, Dongjean | Kyungpook Natl Univ, Dept Appl Biol, Daegu 41566, South Korea; Gyeongsang Natl Univ, Coll Vet Med, Inst Anim Med, Jinju 52828, South Korea; Gyeongsang Natl Univ, Business Ctr, Hoxbio, Jinju 52828, South Korea | 57212468171; 58660497100; 57210995194; 57219914251; 36118279000 | minnamkyong1@gmail.com;jeanmin1@knu.ac.kr;cammayopaula@gmail.com;thanhbinhcnty@gmail.com;dongjean1@naver.com; | MICROORGANISMS | MICROORGANISMS | 2076-2607 | 12 | 3 | SCIE | MICROBIOLOGY | 2024 | 4.2 | 27.9 | 0 | 2025-05-07 | 0 | 0 | Protaetia brevitarsis; third-instar larvae; hindgut microbiota; microbial profiling; microbiota variation | GUT MICROBIOME; BACTERIA | hindgut microbiota; microbial profiling; microbiota variation; Protaetia brevitarsis; third-instar larvae | English | 2024 | 2024-03 | 10.3390/microorganisms12030496 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Gut Microbiome Diversity and Composition in Captive Siberian Tigers (Panthera tigris altaica): The Influence of Diet, Health Status, and Captivity on Microbial Communities | The gut microbiome is essential for the health of carnivorous mammals, including the endangered Siberian tiger (Panthera tigris altaica). However, limited research exists on the gut microbiome of captive Siberian tigers, especially regarding how diet and health status influence microbial diversity. This study addresses this gap by investigating the gut microbiome diversity and composition of six captive-born Siberian tigers housed at the Baekdudaegan National Arboretum in South Korea, using 16S rRNA gene sequencing. The study aimed to examine how diet and health status influence microbial communities, providing baseline data for managing captive tigers. Alpha diversity analysis revealed significant variation in microbial richness and evenness, with Tigers 2 and 6 exhibiting the highest microbial diversity and Tiger 3 the lowest, likely due to its surgical history and limited diet. Beta diversity analysis showed distinct microbial community structures influenced by diet and health. Taxonomic profiling identified Firmicutes and Bacteroidota as the dominant phyla, with Clostridium sensu stricto more prevalent in healthier tigers, while Escherichia-Shigella and Proteobacteria were abundant in tigers with lower diversity, suggesting dysbiosis. Comparisons with other tiger species confirm that diet, health, and captivity significantly shape the gut microbiome. These findings highlight the need for personalized health management in captive environments. | Lee, You-Jeong; Lee, Saebom; Kim, Beoul; Kwak, Dongmi; Kim, Taehwan; Seo, Min-Goo | Kyungpook Natl Univ, Coll Vet Med, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Vet Biomed Sci, 80 Daehak Ro, Daegu 41566, South Korea; Korean Tiger Conservat Ctr, Baekdudaegan Natl Arboretum, 1501 Chunyang Ro, Bonghwa 36209, South Korea | ; Seo, Min-Goo/NQF-4335-2025 | 59343760600; 59449578400; 59343608800; 7007148758; 57202984578; 53982155300 | wowgirlsgood@naver.com;gltp43@koagi.or.kr;kbjjhnm@naver.com;dmkwak@knu.ac.kr;thkim56@naver.com;koreasmg@knu.ac.kr; | MICROORGANISMS | MICROORGANISMS | 2076-2607 | 12 | 11 | SCIE | MICROBIOLOGY | 2024 | 4.2 | 27.9 | 0 | 2025-05-07 | 1 | 1 | gut microbiome; Siberian tiger; alpha diversity; beta diversity; taxonomy profiling; conservation; captivity | alpha diversity; beta diversity; captivity; conservation; gut microbiome; Siberian tiger; taxonomy profiling | English | 2024 | 2024-11 | 10.3390/microorganisms12112165 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Isolation, Characterization, and Safety Evaluation of the Novel Probiotic Strain Lacticaseibacillus paracasei IDCC 3401 via Genomic and Phenotypic Approaches | This study aimed to explore the safety and properties of Lacticaseibacillus paracasei IDCC 3401 as a novel probiotic strain via genomic and phenotypic analyses. In whole-genome sequencing, the genes associated with antibiotic resistance and virulence were not detected in this strain. The minimum inhibitory concentration test revealed that L. paracasei IDCC 3401 was susceptible to all the antibiotics tested, except for kanamycin. Furthermore, the strain did not produce toxigenic compounds, such as biogenic amines and D-lactate, nor did it exhibit significant toxicity in a single-dose acute oral toxicity test in rats. Phenotypic characterization of carbohydrate utilization and enzymatic activities indicated that L. paracasei IDCC 3401 can utilize various nutrients, allowing it to grow in deficient conditions and produce health-promoting metabolites. The presence of L. paracasei IDCC 3401 supernatants significantly inhibited the growth of enteric pathogens (p < 0.05). In addition, the adhesion ability of L. paracasei IDCC 3401 to intestinal epithelial cells was found to be as superior as that of Lacticaseibacillus rhamnosus GG. These results suggest that L. paracasei IDCC 3401 is safe for consumption and provides health benefits to the host. | Lee, Han Bin; Bang, Won Yeong; Shin, Gyu Ri; Jeon, Hyeon Ji; Jung, Young Hoon; Yang, Jungwoo | Ildong Biosci, Pyeongtaek Si 17957, South Korea; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea | ; Jeon, Hyeon Ji/HPH-4892-2023; Jung, Young/F-1703-2013; Jung, Young Hoon/F-1703-2013 | 58843907000; 57208701768; 58845116200; 57795638700; 55550063700; 56076383700 | gksqls9131@ildong.com;yeong0417@ildong.com;li824@naver.com;hhyyeeoonnji@gmail.com;younghoonjung@knu.ac.kr;yjw@ildong.com; | MICROORGANISMS | MICROORGANISMS | 2076-2607 | 12 | 1 | SCIE | MICROBIOLOGY | 2024 | 4.2 | 27.9 | 2.02 | 2025-04-16 | 3 | 3 | probiotics; safety assessment; Lacticaseibacillus paracasei; genome sequencing; lactic acid bacteria | LACTIC-ACID BACTERIA; BIOGENIC-AMINES; ANTIBIOTIC-RESISTANCE; LACTOBACILLUS; METABOLISM; MICROORGANISMS; ADHESION; CULTURES; CASEI | genome sequencing; lactic acid bacteria; Lacticaseibacillus paracasei; probiotics; safety assessment | English | 2024 | 2024-01 | 10.3390/microorganisms12010085 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Taxonomical, Physiological, and Biochemical Characteristics of Dunaliella salina DSTA20 from Hypersaline Environments of Taean Salt Pond, Republic of Korea | Dunaliella salina, a halophilic unicellular chlorophyte, produces bioactive compounds and biofuels applicable to various industries. Despite its industrial significance, comprehensive studies on the morphological, physiological, and biochemical characteristics of the genus Dunaliella remain challenging. In this study, we characterized an axenically isolated green alga from a salt pond in Taean, Republic of Korea, and assessed its industrially relevant traits. The morphological characteristics were typical of D. salina, and molecular phylogenetic analysis of the SSU, ITS1-5.8S-ITS, LSU regions of rDNA, and rbcL gene confirmed the isolate as D. salina strain DSTA20. The optimal temperature, salinity, and photon flux density required for its growth were determined to be 21 degrees C, 0.5 M NaCl, and 88 mu mol m-2 s-1, respectively. Dried biomass analysis revealed 42.87% total lipids, with major fatty acids, including alpha-linolenic acid (31.55%) and palmitic acid (21.06%). The alga produced high-value carotenoids, including beta-carotene (2.47 mg g-1 dry weight (DW)) and lutein (1.39 mg g-1 DW), with peak levels at 0.25 M salinity. Glucose (195.5 mg g-1 DW) was the predominant monosaccharide. These findings highlight the potential of D. salina DSTA20 for biodiesel production and as a source of omega-3 fatty acids, carotenoids, and glucose. Morphological traits provide insights relevant to the industrial potential of the species. | Jo, Chang Rak; Cho, Kichul; An, Sung Min; Do, Jeong-Mi; Hong, Ji Won; Kim, Ju Hyoung; Kim, Sun Young; Jeong, Hyeon Gyeong; Kang, Nam Seon | Natl Marine Biodivers Inst Korea, Seocheon 33662, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Dept Biol, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea; Kyungpook Natl Univ, Adv Bioresource Res Ctr, Daegu 41566, South Korea; Kunsan Natl Univ, Dept Aquaculture & Aquat Sci, Gunsan 54150, South Korea | Kim, Ju-Hyoung/S-6240-2019; Cho, Kichul/IXD-8135-2023; An, Sung-Min/AAC-3888-2021 | 59354978000; 55877400600; 56493979500; 57208562245; 57201579963; 36446122900; 57204790926; 59437212100; 7102653317 | happyccr@mabik.re.kr;kichul.cho@mabik.re.kr;sman@mabik.re.kr;jmdoe09@knu.ac.kr;jwhong@knu.ac.kr;juhyoung@kunsan.ac.kr;sykim@mabik.re.kr;hgjeong@mabik.re.kr;kang3610@mabik.ac.kr; | MICROORGANISMS | MICROORGANISMS | 2076-2607 | 12 | 12 | SCIE | MICROBIOLOGY | 2024 | 4.2 | 27.9 | 0.6 | 2025-05-07 | 1 | 1 | Dunaliella salina; halophilic microalga; taxonomy; biodiesel production; fatty acid profile; carotenoids; monosaccharides; molecular identification | HALOTOLERANT ALGA DUNALIELLA; BETA-CAROTENE; BIODIESEL PRODUCTION; LIPID-CONTENT; PHYLOGENETIC ANALYSIS; CHLORELLA-VULGARIS; BAJA-CALIFORNIA; COASTAL WATERS; DIESEL-ENGINE; MICROALGAE | biodiesel production; carotenoids; Dunaliella salina; fatty acid profile; halophilic microalga; molecular identification; monosaccharides; taxonomy | English | 2024 | 2024-12 | 10.3390/microorganisms12122467 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Napyradiomycin B4 Suppresses RANKL-Induced Osteoclastogenesis and Prevents Alveolar Bone Destruction in Experimental Periodontitis | The unique structure and beneficial biological properties of marine natural products have drawn interest in drug development. Here, we examined the therapeutic potential of napyradiomycin B4 isolated from marine-derived Streptomyces species for osteoclast-related skeletal diseases. Bone marrow-derived macrophages were treated with napyradiomycin B4 in an osteoclast-inducing medium, and osteoclast formation, osteoclast-specific gene expression, and nuclear factor of activated T-cells cytoplasmic 1 (NFATc1) localization were evaluated using tartrate-resistant acid phosphatase staining, real-time PCR, and immunostaining, respectively. Phosphorylation levels of signaling proteins were assessed by immunoblot analysis to understand the molecular action of napyradiomycin B4. The in vivo efficacy of napyradiomycin B4 was examined under experimental periodontitis, and alveolar bone destruction was evaluated by microcomputed tomography (micro-CT) and histological analyses. Among the eight napyradiomycin derivatives screened, napyradiomycin B4 considerably inhibited osteoclastogenesis. Napyradiomycin B4 significantly suppressed the receptor activator of nuclear factor-kappa B ligand (RANKL)-induced osteoclast formation and disrupted the expression of NFATc1 and its target genes. Mitogen-activated extracellular signal-regulated kinase (MEK) and extracellular signal-regulated kinase (ERK) phosphorylation levels were reduced by napyradiomycin B4 in response to RANKL. Under in vivo experimental periodontitis, napyradiomycin B4 significantly attenuated osteoclast formation and decreased the distance between the cementoenamel junction and alveolar bone crest. Our findings demonstrate the antiosteoclastogenic activity of napyradiomycin B4 by inhibiting the RANKL-induced MEK-ERK signaling pathway and its protective effect on alveolar bone destruction. | Kim, Ju Ang; Lim, Soomin; Kim, Geum Jin; Silviani, Velina; Kim, Jung-Eun; Bae, Jong-Sup; Nam, Joo-Won; Choi, Hyukjae; Park, Eui Kyun | Kyungpook Natl Univ, Sch Dent, Dept Oral Pathol & Regenerat Med, IHBR, Daegu 41940, South Korea; Dongguk Univ, Sch Med, Dept Pharmacol, Gyeongju 38066, Gyeong Buk, South Korea; Yeungnam Univ, Res Inst Cell Culture, Gyongsan 38541, Gyeong Buk, South Korea; Yeungnam Univ, Coll Pharm, Gyongsan 38541, Gyeong Buk, South Korea; Kyungpook Natl Univ, Sch Med, CMRI, Dept Mol Med, Daegu 41944, South Korea; Kyungpook Natl Univ, Coll Pharm, Res Inst Pharmaceut Sci, Daegu 41566, South Korea | Kim, Ju Ang/LWI-0914-2024 | 55991948000; 57202647759; 54585532800; 57223237048; 57209054588; 16021543200; 8883246800; 7404339587; 37071072400 | h5choi@yu.ac.kr;epark@knu.ac.kr; | ACS PHARMACOLOGY & TRANSLATIONAL SCIENCE | ACS PHARMACOL TRANSL | 2575-9108 | 7 | 4 | ESCI | CHEMISTRY, MEDICINAL;PHARMACOLOGY & PHARMACY | 2024 | 3.7 | 28.0 | 1.38 | 2025-05-07 | 2 | 2 | napyradiomycin B4; osteoclast; periodontitis; Streptomyces; bone disease | NF-KAPPA-B; LIGATURE-INDUCED PERIODONTITIS; DIFFERENTIATION; NFATC1; ERK; OSTEOPROTEGERIN; ACTIVATION; MECHANISMS; INHIBITOR; INDUCTION | bone disease; napyradiomycin B4; osteoclast; periodontitis; Streptomyces | acid phosphatase tartrate resistant isoenzyme; actin; carbon; carbonyl derivative; cathepsin K; chlorine; colony stimulating factor 1; complementary DNA; dendritic cell specific transmembrane protein; gelatinase B; heme oxygenase 1; mitogen activated protein kinase; mitogen activated protein kinase p38; napyradiomycin B4; natural product; osteoclast differentiation factor; phalloidin; proton; reduced nicotinamide adenine dinucleotide (phosphate) dehydrogenase (quinone); transcription factor NFAT; transcription factor Nrf2; unclassified drug; alveolar bone loss; alveolar crest; animal cell; animal experiment; animal model; animal tissue; antiosteoclastogenic activity; Article; bacterial strain; bone marrow derived macrophage; carbon nuclear magnetic resonance; cementoenamel junction; controlled study; drug activity; drug identification; experimental periodontitis; femur; gene expression; histology; immunoblotting; immunofluorescence; immunohistochemistry; in vivo study; liquid chromatography; male; MAPK signaling; micro-computed tomography; mouse; NF kB signaling; nonhuman; osteoclast; osteoclastogenesis; protein localization; protein phosphorylation; proton nuclear magnetic resonance; real time polymerase chain reaction; reversed phase high performance liquid chromatography; RNA extraction; sediment; South Korea; Streptomyces; tibia | English | 2024 | 2024-04-03 | 10.1021/acsptsci.3c00315 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | A channel estimation method using denoising autoencoder for large-scale asymmetric backscatter systems | A novel channel estimation method based on deep learning algorithm is proposed for large-scale IoT networks. We consider asymmetric backscatter communication system to maintain low-power at sensor nodes. In order to obtain channel data, we design denoising autoencoder which consists of encoder with Feedforward Neural Network (FNN) and decoder with Convolutional Neural Network (CNN). Finally, the channel estimation error is minimized, while the pilots are optimized. Especially, we adopt beamforming technique that relies only on cascaded channel data to reduce complexity in multi-sensor system. It is shown that the accuracy is slightly degraded while the complexity is greatly reduced. (c) 2023 The Author(s).

| ○ | ○ | Article | A novel energy efficient IRS-relay network for ITS with Nakagami-m fading channels | In this paper, we have investigated the performance of energy efficiency (EE) for Intelligent Transportation Systems (ITS), which recently emerged and advanced to preserve speed as well as safe transportation expansion via a cooperative IRS-relay network. To improve the EE, the relay model has been integrated with an IRS block consisting of a number of passive reflective elements. We analyze the ITS in terms of EE, and achievable rate, with different signal-to-noise ratio (SNR) values under Nakagami-m fading channel conditions that help the system to implement in a practical scenario. From the numerical results it is noticed that the EE for the only relay, IRS, and proposed cooperative relay-IRS-aided network at SNR value of 100 dBm is 30, 17, and 48 bits/joule respectively. In addition, we compare the impact of multi-IRS with the proposed cooperative IRS-relay and conventional relay-supported ITS. Simulation results show that both the proposed cooperative IRS-relay-aided ITS network and multi-IRS-aided network outperform the relay-assisted ITS with the increase in SNR. (c) 2023 The Author(s).

| ○ | ○ | Article | Cell-free massive multiple-input multiple-output challenges and opportunities: A survey | Cell-free (CF) massive multiple-input multiple-output (mMIMO) system is a state-of-the-art emerging technology targeted towards beyond fifth-generation (B5G) and sixth-generation (6G) communication networks. This network pertains to a dense deployment of access points (APs) dispersed over a large geographical area to serve a small number of users at the same frequency and time resources. The CF-mMIMO architecture offers resilient connectivity, interference management, power efficiency, high throughput, and macrodiversity. Moreover, this communication technique eliminates cell boundaries and facilitates the users by introducing overlapping regions, thus providing consistent quality of service (QoS) throughout the region. However, the complexity of CF-mMIMO systems increases considerably when numerous APs are dispersed over a large geographical area. Therefore, several studies have been carried out to determine the optimal solution with minimum complexity of the CF-mMIMO system. Herein, a thorough investigation of the literature on the CF-mMIMO system is presented, considering all aspects from architecture to applications. The study provides a detailed survey of CF-mMIMO architecture, fronthaul, and backhaul, as well as the challenges associated with them; deployment methodologies and challenges for practical implementation of CF-mMIMO systems are also discussed. Furthermore, we reviewed the impact of transmitter and receiver antennae on the capacity of CF-mMIMO enabled with millimeter wave (mmWave). The numerical findings indicate that the higher degree of freedom required for spatial multiplexing allows multiantenna users to surpass single-antenna users in terms of capacity. This study holds significance owing to the thorough examination of the CF-mMIMO system model, channel estimation, scalability problems, working algorithms, communication protocol, deep learning-based solutions, linkage to B5G and 6G, and key challenges. Moreover, this study presents a detailed discussion and research survey on the system model, deployment issues, deep learning, and potential applications of the CF-mMIMO system. | Ajmal, Mahnoor; Siddiqa, Ayesha; Jeong, Bomi; Seo, Junho; Kim, Dongkyun | Kyungpook Natl Univ, Dept Comp Sci, Daegu, South Korea | ; 마, 누르아즈말/NRY-5736-2025 | 57238144300; 57811639800; 57831999800; 57208740581; 35753648800 | mahnoor.ajmal@knu.ac.kr;asiddiqa@knu.ac.kr;jbm@knu.ac.kr;jhseo@knu.ac.kr;dongkyun@knu.ac.kr; | ICT EXPRESS | ICT EXPRESS | 2405-9595 | 10 | 1 | SCIE | TELECOMMUNICATIONS;COMPUTER SCIENCE, INFORMATION SYSTEMS | 2024 | 4.2 | 28.1 | 2.04 | 2025-05-07 | 9 | 11 | CF-mMIMO; Opportunities; Challenges; Deployment; B5G; Deep learning | PILOT ASSIGNMENT; ENERGY EFFICIENCY; POWER ALLOCATION; MIMO NETWORKS; ACCESS; UPLINK; DESIGN; BACKHAUL; SYSTEMS; 5G | B5G; CF-mMIMO; Challenges; Deep learning; Deployment; Opportunities | English | 2024 | 2024-02 | 10.1016/j.icte.2023.10.007 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Enhancement of localized superconductivity in BaFe2As2 films via Co-ion implantation | In this study, we present a novel approach to localized superconductivity induction in BaFe2As2 films via targeted implantation of cobalt (Co) ions. Primarily, our study focuses on the systematic distribution of Co ions and the subsequent evolution of superconducting properties in Co-ion-implanted BaFe2As2 films. Our observations show that Co-ion distribution in the films is congruent with the results of analytical methodologies employed in the semiconductor industry, as confirmed via transmission electron microscopy imaging. The temperature-dependent resistivity curves reveal the concurrent presence of superconducting and non-superconducting regions. Moreover, the superconducting domain demonstrates the typical diamagnetic behavior intrinsic in superconductors. Importantly, Co-ion concentrations of similar to 10(20) cm(-3) can be achieved by finely tuning the beam energy and ion dose. This concentration is instrumental in establishing an effective superconducting percolation pathway within the films. (c) 2024 Author(s).

| ○ | ○ | Article | NUCB1 is required for proper insulin signaling to control longevity in Drosophila | Aim: We examined the novel role of NUCB1(Nucleobindin-1) associated with longevity in Drosophila melanogaster. Methods: We measured the lifespan, metabolic phenotypes, and mRNA levels of Drosophila insulin-like peptides (Dilps), the protein level of phosphorylated AKT, and the localization of FOXO and its target gene expressions in the NUCB1 knockdown condition. Results: NUCB1 knockdown flies show an extended lifespan and metabolic phenotypes such as increased circulating glucose level and starvation resistance. The mRNA expression levels of Dilps and the protein level of phosphorylated AKT, a downstream component of insulin signaling, were decreased in NUCB1 knockdown flies compared with the control flies. Also, the nuclear localization of FOXO and its target gene expressions, such as d4E-BP and InR, were elevated. Conclusions: The results show that NUCB1 knockdown flies exhibits an extended lifespan. These findings suggest that NUCB1 modulates longevity through insulin signaling in Drosophila.

| ○ | ○ | Article | Polypyrrole film formation using DC biasing of substrate in in-solution plasma process | Beyond the existing in-solution plasma (iSP) process used for nanoparticle synthesis, polymer film synthesis has recently been demonstrated via iSP, which occurs at a specific cycle in a substrate with electrical potential. Herein, we propose an iSP reactor designed to tune the characteristics of polypyrrole (PPy) films by applying varied DC biases to the substrate during the solution plasma process. Applying DC bias to the substrate notably enhances the iSP during the negative cycle, thereby generating ionic precursors from pyrrole monomers for PPy film formation. These films demonstrated morphological variances as a function of the applied V-DC. At a low voltage (V-DC = 0.5 kV), a uniform film was formed via a layer-by-layer growth mechanism, and as the voltage was increased, the film exhibited a structured morphology. Specifically, at V-DC = 0.5 kV, the PPy film was successfully coated onto a finely patterned electrode. The proposed iSP process, under specific DC biasing conditions, enables polymer coating without necessitating additional chemicals, catalysts, or masks. This method holds potential for a wide range of applications. | Jang, Hyojun; Jung, Eun Young; Kim, Jae Young; Tae, Heung-Sik | Kyungpook Natl Univ, Coll IT Engn, Sch Elect & Elect Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, Inst Elect Technol, Coll IT Engn, Daegu 41566, South Korea | 57207956623; 57203199724; 57205191453; 7006298844 | jyk@knu.ac.kr;hstae@ee.knu.ac.kr; | APL MATERIALS | APL MATER | 2166-532X | 12 | 5 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY;PHYSICS, APPLIED | 2024 | 4.5 | 28.1 | 0 | 2025-05-07 | 0 | 0 | MULTIPLE NUCLEATION; FABRICATION; NANOPARTICLES; DIFFUSION; DISCHARGE; DESIGN; FTIR | Morphology; Plastic coatings; Polypyrroles; Semiconducting films; Synthesis (chemical); DC bias; Electrical potential; Film formations; Low voltages; Nanoparticle synthesis; Plasma reactors; Polypyrrole film; Pyrrole monomers; Solution plasma process; Solution plasmas; Polymer films | English | 2024 | 2024-05-01 | 10.1063/5.0203623 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
