| ○ | ○ | Article | Pushing the limit of synergy in SnTe-based thermoelectric materials leading to an ultra-low lattice thermal conductivity and enhanced ZT | In the era of sustainable and environmentally friendly energy requirements, alternative sources of energy continue to be fervently sought after. Heat recovery into useful electrical energy from waste heat offers a readily available source of energy with humongous potential. Herein, a non-toxic thermoelectric material, SnTe, is explored. Promising thermoelectric performance is also communicated. Introducing Ge as a single dopant is shown for the first time in SnTe-based materials to introduce amorphous Ge (a-Ge) precipitates into the matrix. These act as an auxiliary contributor to the observed ultra-low lattice thermal conductivity of similar to 0.33 W m(-1) K-1 at 823 K, which is below the reported amorphous limit of SnTe. Bi, which is a known resonant dopant, was further co-doped to fine-tune the electrical properties where a high power factor of similar to 25.7 mu W cm(-1) K-2 is reported. To push the limit of synergy, Sb was added raising the maximum figure of merit ZT to a value of similar to 1.1 at 873 K. With co-doping, dual resonance levels are shown which distorts the density of states (DOS) contributing to an increased band effective mass. In conjunction with the introduction of an amorphous phase, co-doping is ascertained as a practical means for the synthesis of high-performance thermoelectric materials for effective waste-heat recovery applications. | Kihoi, Samuel Kimani; Shenoy, U.

| ○ | ○ | Article | The water-dipping effect of branched poly(ethylene imine) interfacial layers on the performance and stability of polymer:nonfullerene solar cells | Here we report the water-dipping effect of polymeric interfacial layers on the performance of inverted-type polymer solar cells (PSCs) with polymer:nonfullerene bulk heterojunction (BHJ) layers. Aqueous solutions of branched poly(ethylene imine) (bPEI) were spun on indium-tin oxide (ITO)-coated glass substrates to make the interfacial layers with various thicknesses (0.1-5 nm) for the investigation of the bPEI thickness effect. The water-dipping process was carried out by immersing the 2 nm-thick bPEI layer-coated ITO-glasses in deionized water for various dipping times (0-90 min). The inverted-type PSCs were fabricated by spin-coating the BHJ layers on the water-dipped bPEI layers, followed by successive deposition of hole-collecting layers and silver top electrodes. The results showed that the open circuit voltage (VOC) of PSCs could be greatly increased by the insertion of bPEI layers (all thicknesses) thanks to the formation of dipole layers. However, the limited thickness range (0.1-1.5 nm) of bPEI layers could only deliver an enhanced short circuit current density (JSC) owing to the influence of high electrical resistance in the case of thicker bPEI layers. The water-dipped bPEI layers resulted in enhanced VOC and JSC due to the well-maintained work functions and reduced thickness, leading to 2.7-fold improved power conversion efficiency by water-dipping for 30 min. The water-dipping process can optimize the thickness of bPEI interlayers leading to improved power conversion efficiency and good shelf-lifetime in inverted-type polymer:nonfullerene solar cells. | Son, Hyunji; Lee, Woongki; Lee, Sooyong; Kim, Hwajeong; Kim, Youngkyoo | Kyungpook Natl Univ, Organ Nanoelect Lab, Dept Chem Engn, Daegu 41566, South Korea; Kyungpook Natl Univ, KNU Inst Nanophoton Applicat KINPA, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Hydrogen & Renewable Energy, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Environm Sci & Technol, Prior Res Ctr, Daegu 41566, South Korea | 58670981000; 59041346100; 55421486100; 15520531700; 10340424400 | khj217@knu.ac.kr;ykimm@knu.ac.kr; | SUSTAINABLE ENERGY & FUELS | SUSTAIN ENERG FUELS | 2398-4902 | 7 | 21 | SCIE | CHEMISTRY, PHYSICAL;ENERGY & FUELS;MATERIALS SCIENCE, MULTIDISCIPLINARY | 2023 | 5 | 29.7 | 0 | 2025-06-25 | 0 | 0 | ELECTRON-TRANSPORT LAYER; WORK FUNCTION; EFFICIENCY; DEGRADATION; ACCEPTOR; LIGHT | Conversion efficiency; Ethylene; Glass substrates; Heterojunctions; Indium compounds; ITO glass; Open circuit voltage; Plastic coatings; Polymer solar cells; Tin oxides; Bulk heterojunction; Coated glass substrates; Deionised waters; Dipping effects; Glasses In; Indium tin oxide coated glass; Interfacial layer; Performance; Poly(ethyleneimine); Thickness effect; deposition; electrical resistivity; electrode; fuel cell; polymer; solar power; Deionized water | English | 2023 | 2023-10-24 | 10.1039/d3se00831b | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||

| ○ | ○ | Article | Aberration-free warp projection on a horopter screen using freeform holographic optical elements | A horopter screen has been popularly studied since its curvature reduces the parallax between two eyes and the immersive displays with a horopter-curved screen are regarded to provide vivid impression of depth and stereopsis. But, the projection on a horopter screen causes some practical problems that the image is hard to be focused on the entire screen and its magnification is partially different. An aberration-free warp projection has a great potential to solve these problems, which changes the optical path from an object plane to an image plane. Since the variation of the curvature is severe in the horopter screen, a freeform optical element is required for an aberration-free warp projection. In comparison with the traditional fabrication method, the hologram printer has the advantage of rapidly manufacturing free-form optical devices by recording the desired wavefront phase on the holographic medium. In this paper, for a given arbitrary horopter screen, the aberration-free warp projection is implemented with the freeform holographic optical elements (HOEs) fabricated by our tailor-made hologram printer. We experimentally demonstrate that the distortion and defocus aberration are effectively corrected. | Jeon, Hosung; Kim, Youngmin; Hahn, Joonku | Kyungpook Natl Univ, Sch Elect & Elect Engn, 80 Daehak Ro, Daegu 41566, South Korea; Korea Elect Technol Inst, Hologram Res Ctr, 8 Floor,11 World Cup Buk Ro 54 Gil, Seoul 03924, South Korea | 56663784700; 57221435538; 10142501600 | jhahn@knu.ac.kr; | OPTICS EXPRESS | OPT EXPRESS | 1094-4087 | 31 | 5 | SCIE | OPTICS | 2023 | 3.2 | 29.8 | 0.32 | 2025-06-25 | 2 | 2 | IMAGING-SYSTEMS; OPTIMIZATION; ENHANCEMENT | Aberrations; Geometrical optics; Holographic optical elements; Printing presses; Aberration-free; Fabrication method; Freeform optical elements; Freeforms; Horopters; Image plane; Immersive display; Object planes; Optical path; Practical problems; Holograms | English | 2023 | 2023-02-27 | 10.1364/oe.484960 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||||
| ○ | ○ | Article | Development of a deviated focusing-based optical coherence microscope with a variable depth of focus for high-resolution imaging | The aim of this study was to develop an optically deviated focusing-based variable depth-of-focus (DOF) oriented optical coherence microscopy (OCM) system to improve the DOF in high-resolution and precise focused imaging. In this study, an approach of varying beam diameter using deviated focusing was employed in the sample arm to enhance the DOF and to confirm precise focusing in OCM imaging. The optically deviated focusing technique was used to vary the focal point and DOF by altering the sample arm beam. The efficacy of the variable DOF imaging approach utilizing an optimized sample arm was confirmed by tissue-level imaging, where OCM images with varying DOF were obtained using deviated focusing. Experimentally confirmed lateral resolution of 2.19 mu m was sufficient for the precise non-invasive visualization of abnormalities of fruit specimens. Thus, the proposed variable DOF-OCM system can be an alternative for precisely focused, high-resolution, and variable DOF imaging by improving the DOF in minimum lateral resolution variation. | Abu Saleah, Sm; Seong, Daewoon; Wijesinghe, Ruchire Eranga; Han, Sangyeob; Kim, Shinheon; Jeon, Mansik; Kim, Jeehyun | Kyungpook Natl Univ, Coll IT Engn, Sch Elect & Elect Engn, 80 Daehak Ro, Daegu 41566, South Korea; Univ Sri Jayewardenepura, Fac Technol, Dept Mat & Mech Technol, Pitipana 10200, Homagama, Sri Lanka; Kyungpook Natl Univ, Data Inst, 80 Daehak Ro, Daegu 41566, South Korea | Wijesinghe, Ruchire/K-3797-2016; Kim, Jinhyun/AAK-3695-2020 | 57218499446; 57212512353; 56018152300; 57193695305; 57226603736; 24171094000; 7601373350 | msjeon@knu.ac.kr; | OPTICS EXPRESS | OPT EXPRESS | 1094-4087 | 31 | 2 | SCIE | OPTICS | 2023 | 3.2 | 29.8 | 0.79 | 2025-06-25 | 4 | 5 | TOMOGRAPHY; SPEED; CANCER; OCT | Beam diameters; Depth-of-focus; High resolution; High-resolution imaging; Lateral resolution; Microscopy imaging; Microscopy systems; Optical coherence microscopy; Precise focusing; Variable depth; Focusing | English | 2023 | 2023-01-16 | 10.1364/oe.479709 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Identifying early response genes against apple Marssonina blotch via comparative gene expression analysis between resistant and susceptible cultivars | Apple Marssonina blotch, caused by the fungus Diplocarpon mali (D. mali), is a severe disease in the world. This disease causes early defoliation and reduces fruit quality and tree growth. Considering the importance of defense mechanisms that begin with early reactions, we tried to identify the genes showing early response against D. mali among flavonoid biosynthesis, antioxidants, transcription factors, and pathogenesis-related (PR) genes. We artificially inoculated D. mali suspensions on detached leaves of resistant and susceptible 'Jiguan' and 'Mutsu' apples as cultivars, respectively. Gene expression was examined at 0, 3, 6, 12, 24, 48, and 72 h post inoculation (hpi) and 7, 10, and 13 days post inoculation (dpi) and divided into early (0-12 hpi), middle (24-72 hpi), and late (7-13 dpi) stages. In 'Jiguan' inoculated leaves, up-regulated genes were mainly involved in the flavonoid pathway and antioxidant activity, which most likely have played an antifungal role against D. mali by main-taining free radicals and decreasing oxidative damage in plant cells. In particular, most flavonoid biosynthetic genes are significantly induced in the early stage, implying that they are early response genes. On the contrary, all PR genes were rapidly induced in inoculated 'Mutsu' leaves, especially when symptoms were clearly visible. These results provide insight into the genetic factors that contribute to suppressing or limiting D. mali infection at an early stage. | Park, Si Eun; Ban, Seunghyun; Han, A.

| ○ | ○ | Article | Bacterial Profiles of Brain in Downer Cattle with Unknown Etiology | Downer cow can be caused by muscular paralysis, neurological damage, metabolic disorder, and/or the complication of microbial infection. However, downer cow with unknown etiology is issued because of the non-detection of its bacterial etiological agent. In this study, differences in the bacterial community in brain tissues between downer cattle with unknown etiology and healthy slaughtered cattle are investigated. Bacterial diversity and representative genera between downer and normal cattle were significantly different (p < 0.05). There are significant differences in representative genera of downer and normal cattle, especially the significance, fold change, and area under the receiver operating characteristic curve score (p < 0.05). Furthermore, the prediction of functional genes in brain microbiota between the downer and normal cattle revealed differences in the cluster of orthologous gene categories, such as lipid transport and metabolism, secondary metabolite biosynthesis, and signal transduction (p < 0.05). This study revealed a significant difference in microbiota between the downer and normal cattle. Thus, we demonstrate that representative genera from downer cattle through 16S rRNA gene amplicon sequencing and microbiota analysis have the potential as candidates for bacterial etiological agents for downer cow. | Park, Yeong-Jun; Kang, Gi-Ung; Jeong, Minsoo; Singh, Vineet; Kim, Jongho; Lee, Kyunghyun; Choi, Eun-Jin; Kim, Heui-Jin; Lee, Seungjun; Lee, Sook-Young; Oem, Jae-Ku; Shin, Jae-Ho | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Anim & Plant Quarantine Agcy, Kimcheon Si 39660, South Korea; Jeonbuk Natl Univ, Coll Vet Med, Iksan Si 54596, South Korea; Pukyong Natl Univ, Dept Food Sci & Nutr, Busan 48513, South Korea | ; Lee, Seungjun/S-9826-2019; Singh, Vineet/ABC-7000-2021 | 56275800900; 57211635810; 57292954900; 57211642447; 57202162365; 35183367100; 26651895700; 57223133138; 56437333700; 54410896200; 6506283913; 57224125922 | jku0623@jbnu.ac.kr;jhshin@knu.ac.kr; | MICROORGANISMS | MICROORGANISMS | 2076-2607 | 11 | 1 | SCIE | MICROBIOLOGY | 2023 | 4.1 | 30.1 | 0.17 | 2025-06-25 | 1 | 1 | downer cow; unknown etiology; brain microbiota; next-generation sequencing | DAIRY-COWS; ENCEPHALITIS; PATIENT; MILK | brain microbiota; downer cow; next-generation sequencing; unknown etiology | English | 2023 | 2023-01 | 10.3390/microorganisms11010098 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Ecoinformatic Analysis of the Gut Ecological Diversity of Wild and Captive Long-Tailed Gorals Using Improved ITS2 Region Primers to Support Their Conservation | Ex situ conservation is used to protect endangered wildlife. As captive and wild long-tailed gorals are known to be similar, individuals under ex situ conservation can be reintroduced into nature. However, there is no appropriate indicator to evaluate them. Here, we amplified the internal transcribed spacer 2 (ITS2) region and compared the gut ecological information (eco-information) of captive and wild long-tailed gorals. We validated the existing ITS86F and ITS4 universal primers using reference sequences of the National Center for Biotechnology Information (NCBI) and improved their matching rates. We compared the gut eco-information of captive and wild long-tailed gorals obtained through experiments using the improved primer pair and found that the gut ecological diversity of captive gorals was low. Based on this, we suggested that the gut eco-information can be used as an evaluation index before reintroducing captive long-tailed gorals. Furthermore, we identified four plant types from the gut eco-information of wild long-tailed gorals, which can be the additional food sources to enhance the reduced intestinal ecological diversity of the captive animals. | Park, Chang-Eon; Cho, Bum-Joon; Kim, Min-Ji; Kim, Min-Chul; Park, Min-Kyu; Son, Jang-Ick; Park, Hee-Cheon; Shin, Jae-Ho | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Ex Situ Conservat Inst Designated Minist Environm, Inst Ornithol, Gumi 39105, South Korea; Wildlife Union, Donghae 25802, South Korea; Kyungpook Natl Univ, NGS Core Facil, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Integrat Biotechnol, Daegu 41566, South Korea; Korea Natl Pk Serv, Natl Pk Inst Wildlife Conservaat, Northern Conservat Ctr, Inje 24607, South Korea | Park, Chang Eon/ACL-1997-2022 | 57213511897; 57264158400; 57127351600; 57203466596; 7404490480; 58476070000; 56779256600; 57224125922 | aeonrapt@knu.ac.kr;hl2xsg@hanmail.net;tbd01188@knu.ac.kr;jhshin@knu.ac.kr; | MICROORGANISMS | MICROORGANISMS | 2076-2607 | 11 | 6 | SCIE | MICROBIOLOGY | 2023 | 4.1 | 30.1 | 0.17 | 2025-06-25 | 1 | 1 | conservation biology; fungal ITS2 region primers; in silico primer improvement | ENVIRONMENTAL DNA | conservation biology; fungal ITS2 region primers; in silico primer improvement | English | 2023 | 2023-06 | 10.3390/microorganisms11061368 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Isolation and Evaluation of the Antagonistic Activity of Cnidium officinale Rhizosphere Bacteria against Phytopathogenic fungi (Fusarium solani) | Cnidium officinale Makino, a perennial crop in the Umbeliperae family, is one of Korea's representative forest medicinal plants. However, the growing area of C. officinale has been reduced by plant disease and soil sickness caused by fusarium wilt. This study isolated rhizosphere bacteria from C. officinale, and their antagonistic activity was evaluated against Fusarium solani. Particularly, four isolated strains, namely, PT1, ST7, ST8, and SP4, showed a significant antagonistic activity against F. solani. An in planta test showed that the mortality rates of shoots were significantly low in the PT1-inoculated group. The fresh and dry weights of the inoculated plants were also higher than that of the other groups. The 16S rRNA gene sequencing identified the strain PT1 as Leclercia adecarboxylata, and downstream studies confirmed the production of antagonism-related enzymes such as siderophore and N-acetyl-& beta;-glucosaminidase. The phosphorous solubilizing ability and secretion of related enzymes were also analyzed. The results showed that PT1 strain could be utilized as promising plant growth-promoting rhizobacteria (PGPR) and biocontrol agents (BCAs). | Lee, Seok Hui; Jeon, Su Hong; Park, Jun Young; Kim, Dae Sol; Kim, Ji Ah; Jeong, Hui Yeong; Kang, Jun Won | Kyungpook Natl Univ, Dept Forestry, Daegu 41566, South Korea; Forest Med Resource Res Ctr, NIFoS, Yeongju 36040, South Korea | ; KANG, JUN WON/K-8084-2013 | 58419182700; 58421874800; 58418511600; 58420519800; 37031219900; 57218898962; 35224649300 | svbreqwaiu@naver.com;tnghd8802@naver.com;paul05241@naver.com;skyds4499@naver.com;jiahkim@korea.kr;hdud7281@korea.kr;jwkang15@knu.ac.kr; | MICROORGANISMS | MICROORGANISMS | 2076-2607 | 11 | 6 | SCIE | MICROBIOLOGY | 2023 | 4.1 | 30.1 | 0.84 | 2025-06-25 | 4 | 6 | Bacillus; Cnidium officinale; Fusarium solani; fusarium wilt; Leclercia adecarboxylata; PGPR | LECLERCIA-ADECARBOXYLATA; ANTIFUNGAL ACTIVITY; BACILLUS-SUBTILIS; IDENTIFICATION; EXPRESSION; OXYSPORUM; PHOSPHATE; SUBSTRATE; SEQUENCE; ACID | Bacillus; Cnidium officinale; Fusarium solani; fusarium wilt; Leclercia adecarboxylata; PGPR | English | 2023 | 2023-06 | 10.3390/microorganisms11061555 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Molecular Detection and Genotyping of Theileria spp. in Deer (Cervidae) in Korea | Major clinical symptoms of Theileria infection include fever, anemia, anorexia, jaundice, and decreased milk production. Although several studies have been conducted on tick-borne pathogens, including Theileria in Korea, only a few have focused on Theileria infection in deer, including the Korean water deer. Blood samples from 160 deer were collected and subjected to DNA extraction and polymerase chain reaction (PCR). Next, PCR-positive samples were sequenced and analyzed by constructing a phylogenetic tree. The results showed that the overall infection rate of Theileria was 8.1% (13/160). Infection rates of 100% were observed in the northern and southern regions. However, the study's limitation was its small sample size, wherein five and one samples were analyzed from the northern and southern regions, respectively. The central region exhibited the lowest infection rate of 2.9% (4/140). Infection rates also differed based on seasons, with the highest (18.4%, 9/49) being observed in spring, followed by that in summer (8.9%, 4/45). However, no infection was observed during autumn and winter. A phylogenetic analysis indicated that the PCR-positive samples contained Theileria luwenshuni, which usually infects small ruminants, such as goats and sheep. | Chung, Chang Uk; Lee, Haeseung; Seo, Min-Goo; Lee, Seung-Hun; Kim, Kyoo-Tae; Nazim, Kaifa; Song, Jung-Sun; Bae, Dong Hwa; Rhee, Man Hee; Kwon, Oh-Deog; Kwak, Dongmi | Kyungpook Natl Univ, Coll Vet Med, Daegu 41566, South Korea; Wild Anim Rescue Ctr, Andong 36605, Gyeongbuk, South Korea; Anim & Plant Quarantine Agcy, Vet Epidmiol Div, Gimcheon 39660, Gyeongbuk, South Korea; Chungbuk Natl Univ, Coll Vet Med, Cheongju 28644, Chungbuk, South Korea; Khalsa Coll Vet & Anim Sci, Dept Vet Parasitol, Amritsar 143002, Punjab, India; Yeungjin Univ, Dept Vet Nursing Sci, Daegu 41527, South Korea; Kyungpook Natl Univ, Cardiovasc Res Inst, Daegu 41944, South Korea | Seo, Min-Goo/NQF-4335-2025; Rhee, Man/O-5705-2016; nazim, kaifa/KYQ-6586-2024 | 58730320300; 57202497862; 53982155300; 57203394416; 56680415000; 57205471525; 58731947800; 58729915200; 57211035357; 7402195886; 7007148758 | ccu73@korea.kr;lhspppp@korea.kr;koreasmg@knu.ac.kr;dvmshlee@chungbuk.ac.kr;kyootae@knu.ac.kr;kaifa.nazim@gmail.com;anasong@yju.ac.kr;vetdonna@yju.ac.kr;rheemh@knu.ac.kr;odkwon@knu.ac.kr;dmkwak@knu.ac.kr; | MICROORGANISMS | MICROORGANISMS | 2076-2607 | 11 | 11 | SCIE | MICROBIOLOGY | 2023 | 4.1 | 30.1 | 0.34 | 2025-06-25 | 2 | 2 | Theileria; tick; genotyping; deer; Korean water deer; phylogeny; incidence | DOMESTIC RUMINANTS; BABESIA; CATTLE; PREVALENCE; INFECTION; TICKS; EPIDEMIOLOGY; PIROPLASMS; ANNULATA; BIOLOGY | deer; genotyping; incidence; Korean water deer; phylogeny; Theileria; tick | English | 2023 | 2023-11 | 10.3390/microorganisms11112740 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Review | Relationship between Human Papillomavirus Status and the Cervicovaginal Microbiome in Cervical Cancer | Uterine cervical cancer (CC) is a complex, multistep disease primarily linked to persistent infection with high-risk human papillomavirus (HR-HPV). However, it is widely acknowledged that HR-HPV infection alone cannot account for the formation and progression of CC. Emerging evidence suggests that the cervicovaginal microbiome (CVM) also plays a significant role in HPV-related CC. Certain bacteria, such as Fusobacterium spp., Porphyromonas, Prevotella, and Campylobacter, are currently being considered as potential microbiomarkers for HPV-positive CC. However, the composition of the CVM in CC is inconsistent; thus, further studies are needed. This review comprehensively discusses the complex interplay between HPV and the CVM in cervical carcinogenesis. It is postulated that the dynamic interaction between HPV and the CVM creates an imbalanced cervicovaginal microenvironment that triggers dysbiosis, enhances HPV persistence, and promotes cervical carcinogenesis. Moreover, this review aims to provide updated evidence on the potential role of bacteriotherapy, particularly probiotics, in the treatment of CC. | Nguyen, Hong Duc Thi; Le, Tan Minh; Lee, Eunmi; Lee, Donghyeon; Choi, Yeseul; Cho, Junghwan; Park, Nora Jee-Young; Chong, Gun Oh; Seo, Incheol; Han, Hyung Soo | Kyungpook Natl Univ, Grad Sch, Dept Biomed Sci, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, BK21 Four Program, Daegu 41944, South Korea; Kyungpook Natl Univ, Clin Om Inst, Daegu 41405, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pathol, Daegu 41944, South Korea; Kyungpook Natl Univ Chilgok Hosp, Dept Pathol, Daegu 41404, South Korea; Kyungpook Natl Univ, Sch Med, Dept Obstet & Gynecol, Daegu 41944, South Korea; Kyungpook Natl Univ Chilgok Hosp, Dept Obstet & Gynecol, Daegu 41404, South Korea; Kyungpook Natl Univ, Sch Med, Dept Immunol, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Physiol, Daegu 41944, South Korea | ; Cho, Junghwan/AAK-4752-2020; Le, Tan/ITT-2150-2023 | 57870555300; 57870749600; 57424697000; 57870503500; 57226123444; 57424663500; 57226185359; 23099068000; 56022683900; 7401969388 | iseo@knu.ac.kr;hshan@knu.ac.kr; | MICROORGANISMS | MICROORGANISMS | 2076-2607 | 11 | 6 | SCIE | MICROBIOLOGY | 2023 | 4.1 | 30.1 | 0.95 | 2025-06-25 | 15 | 15 | cervicovaginal microbiome; human papillomavirus; cervical cancer; cervical intraepithelial lesion; bacteriotherapy | PROBIOTICS; RESPONSES; RISK; INDUCTION; RECEPTOR; TYPE-16; HEALTH; CYCLE | bacteriotherapy; cervical cancer; cervical intraepithelial lesion; cervicovaginal microbiome; human papillomavirus | English | 2023 | 2023-06 | 10.3390/microorganisms11061417 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | Article | Ruminant Salivary Microbes: Passenger or Player in the Rumen? | Sampling of ruminant saliva has gained interest as a non-invasive proxy for exploring the structure of the rumen microbiome. However, the subsequent data analysis assumes that bacteria originating from the oral cavity are merely passengers in the rumen and play no active role. In this study, it was hypothesised that metabolically active oral bacteria present in the salivary microbiome play a role in the ruminal degradation of plant material. In vitro cultivation-based enumeration confirmed that the ruminant oral cavity harbours a significant number of anaerobic and cellulolytic bacteria that are metabolically active under ruminal conditions. Bacterial 16S rRNA gene profiling of in vitro enrichments also confirmed that oral-derived bacteria were capable of colonising plant material. Preliminary analysis of the colonising bacteria indicated that bacteria belonging to the genus Streptococcus were of particular interest. In conclusion, the findings of the current study clearly indicate that bolus-associated bacteria have the potential to play a metabolically active role in terms of ruminal colonisation and the degradation of plant material. This evidence confirms the merit of the hypothesis that the metabolically active oral bacteria present in the salivary microbiome may play a role in the ruminal degradation of plant material. | Edwards, Joan E.; Kim, Eun Joong; Davies, David R.; Hanafy, Radwa; Kingston-Smith, Alison H. | Aberystwyth Univ, Inst Biol Environm & Rural Sci, Gogerddan Campus, Aberystwyth SY23 3EE, Wales; Univ Delaware, Dept Chem & Biomol Engn, Newark, DE 19716 USA; Palital Feed Addit BV, De Tweede Geerden 11, NL-5334 LH Velddriel, Netherlands; Kyungpook Natl Univ, Dept Anim Sci, Sangju 37224, South Korea; Silage Solut Ltd, Pontrhydygroes SY25 6DP, Wales | Kim, Eun Joong/HGF-1639-2022; Edwards, Joan/I-5797-2015 | joanee2002@hotmail.com;ejkim2011@knu.ac.kr;dave.silage@gmail.com;radwa@udel.edu;ahk@aber.ac.uk; | MICROORGANISMS | MICROORGANISMS | 2076-2607 | 11 | 10 | SCIE | MICROBIOLOGY | 2023 | 4.1 | 30.1 | 1 | bolus; bacteria; colonisation; ruminal; oral; saliva | EQUINUS COMPLEX; BACTERIAL; SEQUENCE; COLONIZATION; ATTACHMENT; DIGESTION; NOV. | English | 2023 | 2023-10 | 10.3390/microorganisms11102390 | 바로가기 | 바로가기 | 바로가기 | ||||||||||
| ○ | ○ | Article | Temporomandibular disorders-related videos on YouTube are unreliable sources of medical information: A cross-sectional analysis of quality and content | ObjectiveThe amount of online medical information available is rapidly growing and YouTube is considered as the most popular source of healthcare information nowadays. However, no study has been conducted to comprehensively evaluate YouTube videos related to temporomandibular disorders (TMD). So this study aimed to evaluate the content and quality of YouTube videos as a source of medical information on TMD. MethodA total of 237 YouTube videos that were systematically searched using five keywords (temporomandibular disorders, tmd, temporomandibular joint, tmj, and jaw joint) were included. Included videos were categorized by purpose and source for analysis. The quality (DISCERN, Health on the Net (HON), Ensuring Quality Information for Patients (EQIP), and Global Quality Scale (GQS)) and scientific accuracy of video contents were evaluated. ResultsTotal content, DISCERN, HON, EQIP, and GQS scores were 7.5%, 38.9%, 35.2%, 53.0%, and 48.6% of the maximum possible score, respectively. Only 69 videos (29.1%) were considered as "useful" for patients. News media, physician, and medical source videos showed higher evaluation scores than others. Quality evaluation scores were not significantly correlated or negatively correlated with public preference indices. In the ROC curve analysis, content and DISCERN score showed above excellent discrimination ability for high-quality videos based on GQS (P < 0.001) and total score (P < 0.001). ConclusionsYouTube videos related to TMD contained low quality and scientifically inaccurate information that could negatively influence patients with TMD. | Kim, Moon Jong; Kim, Ji Rak; Jo, Jung Hwan; Kim, Ju Sik; Park, Ji Woon | Seoul Natl Univ, Gwanak Dent Hosp, Dept Oral Med, Seoul, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Oral Med, Daegu Gwangyeogsi, South Korea; Seoul Natl Univ, Sch Dent, Dept Oral Med & Oral Diag, Seoul, South Korea; Seoul Natl Univ, Dent Hosp, Dept Oral Med, Seoul, South Korea; Seoul Natl Univ, Hosp, Dept Dent, Seoul, South Korea; Seoul Natl Univ, Dent Res Inst, Seoul, South Korea; Seoul Natl Univ, Dent Res Inst, Sch Dent, Dept Oral Med & Oral Diag, 101,Daehak ro, Seoul 03080, South Korea | Kim, Jusik/JKJ-0038-2023; Kim, Mark/HZH-8733-2023; Park, Ji Woon/AAS-7375-2020 | 57202488564; 57207438323; 57201340742; 58097457400; 35778690000 | ankara01@snu.ac.kr; | DIGITAL HEALTH | DIGIT HEALTH | 2055-2076 | 9 | SCIE;SSCI | HEALTH CARE SCIENCES & SERVICES;HEALTH POLICY & SERVICES;MEDICAL INFORMATICS;PUBLIC, ENVIRONMENTAL & OCCUPATIONAL HEALTH | 2023 | 2.9 | 30.1 | 1.75 | 2025-06-25 | 11 | 11 | YouTube; videos; temporomandibular disorders; content assessment; global quality scale; DISCERN | INTERNET-BASED INFORMATION; HEALTH; PATIENT; WRITTEN; INSTRUMENT; SURGERY | content assessment; DISCERN; global quality scale; temporomandibular disorders; videos; YouTube | English | 2023 | 2023 | 10.1177/20552076231154377 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | The Alteration of the Gut Microbiome during Ramadan Offers a Novel Perspective on Ramadan Fasting: A Pilot Study | An intermittent fasting regimen is widely perceived to lead to various beneficial health effects, including weight loss, the alleviation of insulin resistance, and the restructuring of a healthy gut microbiome. Because it shares certain commonalities with this dietary intervention, Ramadan fasting is sometimes misinterpreted as intermittent fasting, even though there are clear distinctions between these two regimens. The main purpose of this study is to verify whether Ramadan fasting drives the same beneficial effects as intermittent fasting by monitoring alterations in the gut microbiota. We conducted a study involving 20 Muslim individuals who were practicing Ramadan rituals and assessed the composition of their gut microbiomes during the 4-week period of Ramadan and the subsequent 8-week period post-Ramadan. Fecal microbiome analysis was conducted, and short-chain fatty acids (SCFAs) were assessed using liquid-chromatography-mass spectrometry. The observed decrease in the levels of SCFAs and beneficial bacteria during Ramadan, along with the increased microbial diversity post-Ramadan, suggests that the daily diet during Ramadan may not provide adequate nutrients to maintain robust gut microbiota. Additionally, the notable disparities in the functional genes detected through the metagenomic analysis and the strong correlation between Lactobacillus and SCFAs provide further support for our hypothesis. | Jo, Youngjae; Lee, Gyudae; Ahmad, Sajjad; Son, Hyunwoo; Kim, Min-Ji; Sliti, Amani; Lee, Seungjun; Kim, Kyeongnam; Lee, Sung-Eun; Shin, Jae-Ho | Kyungpook Natl Univ, Dept Appl Biosci, Daegu 41566, South Korea; Pukyong Natl Univ, Dept Food & Nutr, Coll Fisheries Sci, Busan 608737, South Korea; Kyungpook Natl Univ, Inst Qual & Safety Evaluat Agr Prod, Daegu 41566, South Korea; Kyungpook Natl Univ, Dept Integrat Biol, Daegu 41566, South Korea; Kyungpook Natl Univ, NGS Ctr, Daegu 41566, South Korea | ; Kim, Kyeongnam/KSM-2719-2024; Lee, Seungjun/S-9826-2019 | 57214743390; 57222101785; 57225072939; 57218872919; 57127351600; 58551490600; 56437333700; 57191364349; 55890041600; 57224125922 | dudwo7573@knu.ac.kr;leegyuedae@gmail.com;sajjadahmedbot1310@gmail.com;thsgusdn2@knu.ac.kr;tbd01188@knu.ac.kr;amanisliti25102020@gmail.com;paul5280@pknu.ac.kr;kn1188@knu.ac.kr;selpest@knu.ac.kr;jhshin@knu.ac.kr; | MICROORGANISMS | MICROORGANISMS | 2076-2607 | 11 | 8 | SCIE | MICROBIOLOGY | 2023 | 4.1 | 30.1 | 0.51 | 2025-06-25 | 3 | 3 | Ramadan fasting; intermittent fasting; microbiome; short-chain fatty acids; Lactobacillus | CHAIN FATTY-ACIDS; BODY-COMPOSITION; HEALTH MARKERS; DIETARY FIBER; INTERMITTENT; FRAGILIS | intermittent fasting; Lactobacillus; microbiome; Ramadan fasting; short-chain fatty acids | English | 2023 | 2023-08 | 10.3390/microorganisms11082106 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
