| ○ | ○ | Article | Spray Mode and Monodisperse Droplet Properties of an Electrospray | As a method of fluid atomization via application of a high voltage, electrospraying forms more uniform droplets than other spraying modes. This approach involves various spraying modes depending on the applied voltage. Most previous studies on electrospraying focused on the cone jet mode, which has limited applications since the applied voltage has a narrow range. To overcome this limitation, it is necessary to consider alternative spray modes, which require an in-depth understanding of their characteristics. To compare different spray modes, an investigation was conducted based on experimental parameters and fluid properties. In this study, a total of nine modes were identified, and the droplet characteristics in four modes were compared. The maximum deviation of the Sauter mean diameter (SMD) between the spray modes was approximately 1.7 times, and the SMD standard deviation was up to 2.8 times. In addition, the conditions required to realize Coulomb fission and monodisperse distribution depending on the Rayleigh critical charge (RSD < 6.76) were compared and examined. | Kim, Ji Yeop; Lee, Sang Ji; Hong, Jung Goo | Kyungpook Natl Univ, Sch Mech Engn, Daegu 41566, South Korea | 57222525959; 57221453424; 24576652200 | jghong70@knu.ac.kr; | ACS OMEGA | ACS OMEGA | 2470-1343 | 7 | 32 | SCIE | CHEMISTRY, MULTIDISCIPLINARY | 2022 | 4.1 | 38.5 | 1.18 | 2025-06-25 | 15 | 18 | NANOPARTICLES; MICROSTRUCTURES; CONDUCTIVITY; FABRICATION; GENERATION | English | 2022 | 2022-08-16 | 10.1021/acsomega.2c04002 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||||

| ○ | ○ | Review | Role, relevance, and possibilities of in vitro fermentation models in human dietary, and gut-microbial studies | Dietary studies play a crucial role in determining the health-benefiting effects of most food substances, including prebiotics, probiotics, functional foods, and bioactive compounds. Such studies involve gastrointestinal digestion and colonic fermentation of dietary substances. In colonic fermentation, any digested food is further metabolized in the gut by the residing colonic microbiota, causing a shift in the gut microenvironment and production of various metabolites, such as short-chain fatty acids. These diet-induced shifts in the microbial community and metabolite production, which can be assessed through in vitro fermentation models using a donor's fecal microbiota, are well known to impact the health of the host. Although in vivo or animal experiments are the gold standard in dietary studies, recent advancements using different in vitro systems, like artificial colon (ARCOL), mini bioreactor array (MBRA), TNO in vitro model of the colon (TIM), Simulator of the Human Intestinal Microbial Ecosystem (SHIME), M-SHIME, Copenhagen MiniGut, and Dynamic Gastrointestinal Simulator, make it easy to study the dietary impact in terms of the gut microbiota and metabolites. Such a continuous in vitro system can have multiple compartments corresponding to different parts of the colon, that is, proximal, transverse, and distal colon, making the findings physiologically more significant. Furthermore, postfermentation samples can be analyzed using metagenomic, metabolomic, quantitative-polymerase chain reaction, and flow-cytometry approaches. Moreover, studies have shown that in vitro results are in accordance with the in vivo findings, supporting their relevance in dietary studies and giving confidence that shifts in metabolites are only due to microbes. This review meticulously describes the recent advancements in various fermentation models and their relevance in dietary studies. | Singh, Vineet; Son, HyunWoo; Lee, GyuDae; Lee, Sunwoo; Unno, Tatsuya; Shin, Jae-Ho | Kyungpook Natl Univ, Dept Appl Biosci, 80 Daehak Ro, Bukgu 41566, Daegu, South Korea; Jeju Natl Univ, Dept Biotechnol, SARI, Jeju, South Korea | ; shin, Jaeho/K-6792-2013; Unno, Tatsuya/C-1522-2012; Singh, Vineet/ABC-7000-2021 | 57211642447; 57218872919; 57222101785; 57375227200; 22941915600; 57224125922 | singhvineet@knu.ac.kr;thsgusdn2@knu.ac.kr;tatsu@jejunu.ac.kr;jhshin@knu.ac.kr; | BIOTECHNOLOGY AND BIOENGINEERING | BIOTECHNOL BIOENG | 0006-3592 | 1097-0290 | 119 | 11 | SCIE | BIOTECHNOLOGY & APPLIED MICROBIOLOGY | 2022 | 3.8 | 38.9 | 0.61 | 2025-06-25 | 16 | 17 | colonic fermentation; fermentation model; gut microbiota; in vitro fecal fermentation; metabolites | GASTROINTESTINAL DIGESTION; FECAL FERMENTATION; PROBIOTIC STRAINS; LARGE-INTESTINE; COLON; SIMULATOR; COMMUNITY; POLYSACCHARIDES; POLYDEXTROSE; METABOLISM | colonic fermentation; fermentation model; gut microbiota; in vitro fecal fermentation; metabolites | Animals; Colon; Diet; Fatty Acids, Volatile; Fermentation; Humans; Microbiota; Prebiotics; Biomolecules; Fatty acids; Fermentation; Food microbiology; Polymerase chain reaction; Probiotics; prebiotic agent; volatile fatty acid; Colonic fermentation; Fermentation model; Gut microbiota; Human guts; In vitro fecal fermentation; In-vitro; Microbial ecosystem; Prebiotics; Vitro fermentation; Vitro system; colon; diet; fermentation; fermentation model; human; in vitro study; intestine flora; microbial community; nonhuman; Review; animal; metabolism; microflora; Metabolites | English | 2022 | 2022-11 | 10.1002/bit.28206 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |

| ○ | ○ | Article | Safety of surgical hip dislocation in femoral head fracture and dislocation (FHFD) and avascular necrosis risk factor analysis of FHFD: midterm results confirmed by SPECT/CT and MRI | Background The study aim was to report the treatment outcomes of trochanteric flip osteotomy (TFO) with surgical hip dislocation (SHD) for femoral head fracture and dislocation (FHFD) and to investigate the risk factors for avascular necrosis (AVN) of the femoral head. Methods The data of 34 patients (29 men, 5 women; mean age 37.9 years) diagnosed with FHFD and treated with TFO with SHD between May 2009 and February 2018 with an average follow-up period of 5.1 years (range 2.8-10.5 years) were analyzed. Clinical outcomes were evaluated using the Merle d'Aubigne-Postel score and Thompson-Epstein Scale. Radiologic outcomes were classified according to the Matta classification. AVN was confirmed using magnetic resonance imaging or single-photon emission computed tomography/computed tomography. The occurrence of complications was examined, and factors influencing complications, AVN. Results Regarding the Pipkin's classification, there were 7 patients with type II, 2 patients with type III, and 25 patients with type IV fractures. Posterior wall fractures accompanied all associated acetabular fractures in the patients with Pipkin type IV fractures. Radiologically, the union of acetabular and femoral head fractures was observed within 6.1 months on average (range 4-10 months) in 32 patients, except two patients who developed femoral head AVN. Clinically, the average Merle d'Aubigne-Postel score was 14.4 points (range 8-17 points), and 22 patients had good or excellent results on the Thompson-Epstein Scale. Two patients developed femoral head AVN with both having displaced femoral neck fractures associated with FHFD. AVN was significantly correlated with femoral neck fractures (P = 0.000). Conclusion TFO with SHD is a safe and useful approach for the treatment of FHFD. Particular attention should be paid when treating femoral head fractures associated with displaced femoral neck fractures because of the high risk of AVN development. | Yoon, Yong-Cheol; Oh, Chang-Wug; Kim, Joon-Woo; Heo, Jeong; Song, Hyung Keun | Gachon Univ, Trauma Ctr, Orthoped Trauma Div, Coll Med, Incheon, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Ortho Ped Surg, 130 Dongdeok Ro, Daegu 41944, South Korea; Ajou Univ, Dept Orthoped Surg, Sch Med, Suwon, Gyeonggi Do, South Korea | ; Yong-Cheol, Yoon/HPD-8077-2023; Oh, Chang-Wug/AAO-4602-2021; Jeong, Sook-Hyang/J-5642-2012 | 37082544400; 22135834200; 22951329000; 56970488400; 55350292600 | cwoh@knu.ac.kr; | JOURNAL OF ORTHOPAEDIC SURGERY AND RESEARCH | J ORTHOP SURG RES | 1749-799X | 17 | 1 | SCIE | ORTHOPEDICS | 2022 | 2.6 | 39.0 | 1.82 | 2025-06-25 | 8 | 10 | Femoral head fracture and dislocation; Trochanteric flip osteotomy; Surgical hip dislocation; Avascular necrosis; Displaced femoral neck fractures | EXPERIENCE; MANAGEMENT; ACETABULUM; FIXATION | Avascular necrosis; Displaced femoral neck fractures; Femoral head fracture and dislocation; Surgical hip dislocation; Trochanteric flip osteotomy | Acetabulum; Child; Child, Preschool; Factor Analysis, Statistical; Female; Femoral Fractures; Femoral Neck Fractures; Femur Head; Femur Head Necrosis; Hip Dislocation; Hip Fractures; Humans; Magnetic Resonance Imaging; Male; Retrospective Studies; Risk Factors; Tomography, Emission-Computed, Single-Photon; Tomography, X-Ray Computed; Treatment Outcome; acetabulum; child; complication; diagnostic imaging; factor analysis; female; femoral head; femoral neck fracture; femur fracture; femur head necrosis; hip dislocation; hip fracture; human; male; nuclear magnetic resonance imaging; preschool child; retrospective study; risk factor; single photon emission computed tomography; treatment outcome; x-ray computed tomography | English | 2022 | 2022-05-16 | 10.1186/s13018-022-03160-y | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Inhibitory Activity of Bioactive Phloroglucinols from the Rhizomes of Dryopteris crassirhizoma on Escherichia coli β-Glucuronidase: Kinetic Analysis and Molecular Docking Studies | Phloroglucinols-one of the major secondary metabolites in Dryopteris crassirhizoma-exhibit various pharmacological effects, such as antiviral, antioxidant, and antidiabetic activities. This study evaluated 30 phloroglucinols isolated from the rhizomes of D. crassirhizoma for their inhibitory activity on beta-glucuronidase via in vitro assays. Among them, dimeric phloroglucinols 13-15 moderately inhibited beta-glucuronidase, and trimeric phloroglucinols 26-28 showed strong inhibitory effects, with IC50 values ranging from 5.6 to 8.0 mu M. Enzyme kinetic analysis confirmed all six active compounds to be in a competitive mode of inhibition. Molecular docking simulations revealed the key binding interactions with the active site of beta-glucuronidase protein and the binding mechanisms of these active metabolites. Our results suggest that the rhizomes of D. crassirhizoma and trimeric compounds 26-28 may serve as potential candidates for discovering and developing new beta-glucuronidase inhibitors. | Nguyen Viet Phong; Zhao, Yan; Min, Byung Sun; Yang, Seo Young; Kim, Jeong Ah | Kyungpook Natl Univ, Coll Pharm, Vessel Organ Interact Res Ctr, VOICE MRC, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll Pharm, BK21 FOUR Community Based Intelligent Novel Drug, Daegu 41566, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Daegu 41566, South Korea; Yantai Univ, Sch Pharm, Yantai 264005, Peoples R China; Daegu Catholic Univ, Coll Pharm, Drug Res & Dev Ctr, Gyongsan 38430, South Korea; Sangji Univ, Dept Pharmaceut Engn, Wonju 26339, South Korea | Nguyen, Viet Phong/AAQ-4207-2021 | 57205196739; 57195927125; 55663638200; 57215036954; 24722570900 | syyang@sangji.ac.kr;jkim6923@knu.ac.kr; | METABOLITES | METABOLITES | 2218-1989 | 12 | 10 | SCIE | BIOCHEMISTRY & MOLECULAR BIOLOGY | 2022 | 4.1 | 39.1 | 1.11 | 2025-06-25 | 11 | 12 | Dryopteris crassirhizoma; phloroglucinols; beta-glucuronidase; kinetic analysis; competitive inhibitor; molecular docking | CONSTITUENTS; DERIVATIVES; TOXICITY | competitive inhibitor; Dryopteris crassirhizoma; kinetic analysis; molecular docking; phloroglucinols; β-glucuronidase | beta glucuronidase; dimer; phloroglucinol; Article; binding affinity; chemical structure; Dryopteris crassirhizoma; enzyme activity; enzyme inhibition; Escherichia coli; hydrogen bond; IC50; in vitro study; kinetics; molecular docking; nonhuman; rhizome; simulation | English | 2022 | 2022-10 | 10.3390/metabo12100938 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Clinical Characteristics and Risk Factors of First-Ever Stroke in Young Adults: A Multicenter, Prospective Cohort Study | Stroke in young adults has catastrophic consequences and has increased in prevalence, contrary to the trends of most other diseases. This study aimed to determine the major characteristics and risk factors for stroke in younger adults compared with older adults. From the Korean Stroke Cohort for Functioning and Rehabilitation, 10,584 patients with first-ever stroke between August 2012 and March 2015 were enrolled retrospectively and divided into younger (age 45). The clinical characteristics and risk factors of stroke were compared between the younger and older groups. The younger group comprised 915 patients (8.6%). The proportion of hemorrhage strokes in the younger group (42.3%) was significantly higher than in the older group (20.0%) (p < 0.001). Obesity, current smoking, and heavy alcohol consumption were significantly more common risk factors in the younger group than in the older group for all stroke types, whereas hypertension, diabetes mellitus, hyperlipidemia, atrial fibrillation, and coronary heart disease were significantly more frequent in the older group (both p < 0.001). The major risk factors in the younger group may be lifestyle-related. Therefore, increasing awareness of lifestyle-related risk factors may be necessary to prevent stroke in young adults. | Jo, Yea Jin; Kim, Dae Hyun; Sohn, Min Kyun; Lee, Jongmin; Shin, Yong-Il; Oh, Gyung-Jae; Lee, Yang-Soo; Joo, Min Cheol; Lee, So Young; Song, Min-Keun; Han, Junhee; Ahn, Jeonghoon; Chang, Won Hyuk; Kim, Yun-Hee; Kim, Deog Young | Yonsei Univ, Res Inst Rehabil Med, Coll Med, Seoul 03722, South Korea; Yonsei Univ, Dept Rehabil Med, Coll Med, Seoul 03722, South Korea; Chungnam Natl Univ, Coll Med, Dept Rehabil Med, Daejon 34134, South Korea; Konkuk Univ, Dept Rehabil Med, Sch Med, Seoul 05030, South Korea; Pusan Natl Univ, Sch Med, Dept Rehabil Med, Yangsan Hosp, Yangsan 46241, South Korea; Wonkwang Univ, Dept Prevent Med, Sch Med, Iksan 51538, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Dept Rehabil Med, Sch Med, Daegu 41566, South Korea; Wonkwang Univ, Dept Rehabil Med, Sch Med, Iksan 51538, South Korea; Jeju Natl Univ, Jeju Natl Univ Hosp, Dept Rehabil Med, Sch Med, Jeju 63243, South Korea; Chonnam Natl Univ, Dept Phys & Rehabil Med, Med Sch, Kwangju 61186, South Korea; Hallym Univ, Dept Stat, Chunchon 24252, South Korea; Ewha Womans Univ, Dept Hlth Convergence, Seoul 03760, South Korea; Sungkyunkwan Univ, Samsung Med Ctr, Sch Med,Ctr Prevent & Rehabil, Heart Vasc Stroke Inst,Dept Phys & Rehabil Med, Seoul 06351, South Korea; Sungkyunkwan Univ, SAIHST, Dept Digital Healthcare, Dept Hlth Sci & Technol,Dept Med Device Managemen, Seoul 03063, South Korea | ; kim, deog young/Q-8498-2019; Ahn, Jeonghoon/CAA-1956-2022; Chang, Won Hyuk/I-5662-2015; Kim, Yun-Hee/GVS-6426-2022; Lee, Jongmin/Q-4909-2019 | 57902616700; 57206099341; 7101840459; 57202882113; 55890990500; 7007056685; 57202952463; 56982599700; 57202327370; 55375416600; 57192890252; 8855402200; 35301717900; 57020121600; 55375583000 | yun1225.kim@samsung.com;kimdy@yuhs.ac; | JOURNAL OF PERSONALIZED MEDICINE | J PERS MED | 2075-4426 | 12 | 9 | SCIE | HEALTH CARE SCIENCES & SERVICES;MEDICINE, GENERAL & INTERNAL | 2022 | 3.4 | 39.2 | 0.68 | 2025-06-25 | 6 | 5 | stroke; risk factors; young adults | ISCHEMIC-STROKE; INTRACEREBRAL HEMORRHAGE; NATIONAL-HEALTH; TRENDS; NUTRITION; SEVERITY; RELIABILITY; PREVALENCE; OUTCOMES; OBESITY | risk factors; stroke; young adults | adult; aged; alcohol consumption; Article; atrial fibrillation; awareness; bleeding; cerebrovascular accident; Charlson Comorbidity Index; clinical feature; cohort analysis; computed tomographic angiography; computer assisted tomography; diabetes mellitus; disease severity; dyslipidemia; epidural hemorrhage; family history; female; Glasgow coma scale; heart left ventricle hypertrophy; human; hyperlipidemia; hypertension; ischemic heart disease; lifestyle; magnetic resonance angiography; major clinical study; male; multicenter study; National Institutes of Health Stroke Scale; neuroimaging; nuclear magnetic resonance imaging; obesity; prospective study; Rankin scale; retrospective study; risk factor; smoking; subarachnoid hemorrhage; young adult | English | 2022 | 2022-09 | 10.3390/jpm12091505 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Effects of Artificial Extraoral Markers on Accuracy of Three-Dimensional Dentofacial Image Integration: Smartphone Face Scan versus Stereophotogrammetry | Recently, three-dimensional (3D) facial scanning has been gaining popularity in personalized dentistry. Integration of the digital dental model into the 3D facial image allows for a treatment plan to be made in accordance with the patients' individual needs. The aim of this study was to evaluate the effects of extraoral markers on the accuracy of digital dentofacial integrations. Facial models were generated using smartphone and stereophotogrammetry. Dental models were generated with and without extraoral markers and were registered to the facial models by matching the teeth or markers (n = 10 in each condition; total = 40). Accuracy of the image integration was measured in terms of general 3D position, occlusal plane, and dental midline deviations. The Mann-Whitney U test and two-way analysis of variance were used to compare results among face-scanning systems and matching methods (a = 0.05). As result, the accuracy of dentofacial registration was significantly affected by the use of artificial markers and different face-scanning systems (p < 0.001). The deviations were smallest in stereophotogrammetry with the marker-based matching and highest in smartphone face scans with the tooth-based matching. In comparison between the two face-scanning systems, the stereophotogrammetry generally produced smaller discrepancies than smartphones. | Mai, Hang-Nga; Lee, Du-Hyeong | Kyungpook Natl Univ, Inst Translat Res Dent, Daegu 41940, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu 41940, South Korea | ; Mai, Hang-Nga/Q-9865-2018 | 56964780900; 35770948000 | mai.hang.nga1403@gmail.com;deweylee@knu.ac.kr; | JOURNAL OF PERSONALIZED MEDICINE | J PERS MED | 2075-4426 | 12 | 3 | SCIE | HEALTH CARE SCIENCES & SERVICES;MEDICINE, GENERAL & INTERNAL | 2022 | 3.4 | 39.2 | 1.76 | 2025-06-25 | 9 | 13 | face scan; dental scan; image integration; extraoral marker; accuracy; stereophotogrammetry; smartphone | VIRTUAL PATIENT; DENTAL CASTS; RELIABILITY; POSITION; VENEERS | accuracy; dental scan; extraoral marker; face scan; image integration; smartphone; stereophotogrammetry | analysis of variance; Article; human; mathematical model; rank sum test; stereophotogrammetry; three-dimensional imaging | English | 2022 | 2022-03 | 10.3390/jpm12030490 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Genome Insight and Description of Previously Uncultured N2-Fixing Bacterium Rhizobium terricola sp. nov., Isolated from Forest Rhizospheric Soil by Using Modified Culture Method | A bacterial strain S-51(T) was isolated from rhizospheric forest soil at Kyonggi University during the study of previously uncultured bacterium. The phylogenetic analysis was based on 16S rRNA gene sequences that indicated that strain S-51(T) belonged to the genus Rhizobium within the family Rhizobiaceae. The closest members of strain S-51(T) were Rhizobium naphthalenivorans TSY03b(T) (98.2% sequence similarity) and Rhizobium selenitireducens ATCC BAA-1503(T) (98.1%). The sequence similarities of other members were <97.7%. The sole respiratory quinone was Q-10 and the major polar lipids were phosphatidylethanolamine, diphosphatidylglycerol, phosphatidylcholine, and unidentified glycolipid. The principal fatty acids were summed feature 8 (C-18:1 omega 7c and/or C-18:1 omega 6c), cyclo-C-19:0 omega 8c, and C-18:0. The DNA G+C content was 63.1 mol%. The genome was 4930044 bp long and contained N-2-fixing genes, such as fixF, ntrC, and ptsN, in addition to respiratory nitrate reductase genes, such as narC, narG, narH, narI, and narJ. The average nucleotide identity (ANIu), average amino acid identity (AAI), and digital DNA-DNA hybridization (dDDH) relatedness between strain S-51(T) and phylogenetically related species were <= 82.6, <= 83.6 and <= 25.3%, respectively, much lower than the species delineation thresholds. Based on the polyphasic taxonomic study, strain S-51(T) represents a new species in the genus Rhizobium, for which the name Rhizobium terricola is proposed. The type strain is S-51(T) (=KACC 19117(T) = KEMB 9005-539(T) = NBRC 112711(T)). | Dahal, Ram Hari; Chaudhary, Dhiraj Kumar; Kim, Jungmin; Kim, Dong-Uk; Kim, Jaisoo | Kyonggi Univ, Coll Nat Sci, Dept Life Sci, Suwon 16227, South Korea; Kyungpook Natl Univ, Sch Med, Dept Microbiol, Daegu 41944, South Korea; Korea Univ, Dept Environm Engn, Sejong City 30019, South Korea; Sangji Univ, Coll Sci & Engn, Dept Biol Sci, Wonju 26339, South Korea | ; Chaudhary, Dhiraj Kumar/S-7772-2016; Dahal, Ram Hari/H-8673-2016; Chaudhary, Dhiraj/S-7772-2016 | 57110097800; 57191257432; 57211297681; 57206099551; 8718834500 | jkimtamu@kgu.ac.kr; | DIVERSITY-BASEL | DIVERSITY-BASEL | 1424-2818 | 14 | 9 | SCIE | BIODIVERSITY CONSERVATION;ECOLOGY | 2022 | 2.4 | 39.2 | 0.27 | 2025-06-25 | 2 | 2 | Rhizobium terricola sp; nov; uncultured bacterium; forest soil; N-2-fixation; alpha-Proteobacteria | NITROGEN-FIXATION; SEQUENCE-ANALYSIS; ALGORITHM | forest soil; N<sub>2</sub>-fixation; Rhizobium terricolasp. nov; uncultured bacterium; α-Proteobacteria | forest soil; genome; new species; nitrogen fixation; rhizobacterium; rhizosphere; taxonomy | English | 2022 | 2022-09 | 10.3390/d14090733 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

In India, it is represented by 11 taxa; among them, Portulaca badamica, Portulaca lakshminarasimhaniana, Portulaca oleracea var. linearifolia, and Portulaca laljii are endemic. So far, the phylogenetic positions of these species have not yet been analyzed. We have reconstructed the Bayesian and maximum likelihood phylogenies based on a combined chloroplast and nuclear DNA sequence dataset to reveal phylogenetic placements of Indian Portulaca. Phylogenetic analyses indicate that all the sampled Indian Portulaca species (except Portulaca wightiana) are placed in the AL clade, which contains most of the known species of the family Portulacaceae. We used reconstructed phylogeny to study the historical biogeography of Indian endemic species by employing S-DIVA analysis. S-DIVA analysis suggested P. lakshminarasimhaniana has origin in India, it may be the result of in situ speciation in India, and P. badamica was dispersed from Africa to India. We have also discussed the systematic placements of endemic species and their morphological relationships with closely allied species. In addition, this study also provides taxonomic treatment for endemic species. | Tamboli, Asif S.; Dalavi, Jagdish V.; Kadam, Suhas K.; Yadav, Shrirang R.; Govindwar, Sanjay P.; Choo, Yeon-Sik; Pak, Jae Hong | Kyungpook Natl Univ, Res Inst Dok Do & Ulleung Do Isl, Sch Life Sci, Dept Biol, 80 Daehak Ro, Daegu 41566, South Korea; Shivaji Univ, Dept Bot, Kolhapur 416004, Maharashtra, India; Balwant Coll, Dept Bot, Vita 415311, Maharashtra, India; Shivaji Univ, Dept Biochem, Kolhapur 416004, Maharashtra, India; Kyungpook Natl Univ, Sch Life Sci, Dept Biol, 80 Daehak Ro, Daegu 41566, South Korea | Kadam, Dr. Suhas/HNI-6437-2023; Tamboli, Asif/HJB-2803-2022; Kadam, Dr Suhas/HNI-6437-2023 | 56974034100; 57200728751; 57188723669; 57203296258; 6603868071; 26040458100; 7102232932 | asift456@gmail.com;jagdishtaxonomy@gmail.com;suhas397@gmail.com;sryadavdu@gmail.com;spgovindwar@rediffmail.com;yschoo@knu.ac.kr;jhpak@knu.ac.kr; | DIVERSITY-BASEL | DIVERSITY-BASEL | 1424-2818 | 14 | 6 | SCIE | BIODIVERSITY CONSERVATION;ECOLOGY | 2022 | 2.4 | 39.2 | 0.4 | 2025-06-25 | 4 | 4 | biogeography; ITS; ndhA; ndhF; Portulaca; phylogeny; trnT-psbD | RECONSTRUCT ANCESTRAL STATE; TOOL | biogeography; ITS; ndhA; ndhF; phylogeny; Portulaca; trnT-psbD | India; angiosperm; biogeography; endemic species; phylogenetics; phylogeny | English | 2022 | 2022-06 | 10.3390/d14060443 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Morphology, Palynology and Molecular Phylogeny of Barleria cristata L. (Acanthaceae) Morphotypes from India | Barleria cristata L., commonly known as the Philippine violet, is native to South Asia. It is an ornamental plant and is also used for the treatment of a variety of diseases. In India, it is found throughout the country in many forms, varying in its floral attributes (calyx and corolla) and habitat. In order to understand the species limits in B. cristata, we studied morphological as well as palynological variation and assessed the phylogenetic relationships among five different morphotypes. The studied morphotypes (populations) came from three phytogeographical regions, namely the Western Ghats, the Deccan Peninsula and the Western Himalaya. The naturally occurring populations from the Deccan Peninsula and the Western Himalaya showed conspicuous differences in their morphology. All the morphotypes had oblate spheroidal, tri-brevicolporate and honey-combed pollen grains which differed only in their quantitative parameters. The distinct-looking morphotypes, namely, Nandi Hills, Uttarakhand and cultivated morphotypes, could not be separated based on pollen characters. Phylogenetic analyses based on chloroplast DNA sequences revealed that our samples formed a clade sister to the B. cristata specimen used in the previous study. The genetic variation within morphotypes was not enough for the genomic regions investigated; however, it revealed among morphotype genealogies in detail. Phylogenetic analyses showed that there were three monophyletic groups within the B. cristata complex that exhibited some morphological differences. Nevertheless, based on the present sampling, it is not possible to delimit these morphotypes at specific or infraspecific level. To reach such conclusions, further investigations like sampling this species across its distribution range in India and assessment of intraspecific relationships, and their cytogenetical characterization should be done. | Tamboli, Asif S.; Patil, Suraj S.; Kadam, Suhas K.; Choo, Yeon-Sik; Lekhak, Manoj M.; Pak, Jae Hong | Kyungpook Natl Univ, Res Inst Dok Do & Ulleung Do Isl, Sch Life Sci, Dept Biol, 80 Daehak Ro, Daegu 41566, South Korea; Shivaji Univ, Dept Bot, Angiosperm Taxon Lab, Kolhapur 416004, Maharashtra, India; Kyungpook Natl Univ, Sch Life Sci, Dept Biol, 80 Daehak Ro, Daegu 41566, South Korea | Lekhak, Manoj/AAP-5079-2020; Kadam, Dr Suhas/HNI-6437-2023; Tamboli, Asif/HJB-2803-2022; Kadam, Dr. Suhas/HNI-6437-2023 | 56974034100; 57196715364; 57188723669; 26040458100; 35573958700; 7102232932 | mml_botany@unishivaji.ac.in;jhpak@knu.ac.kr; | DIVERSITY-BASEL | DIVERSITY-BASEL | 1424-2818 | 14 | 8 | SCIE | BIODIVERSITY CONSERVATION;ECOLOGY | 2022 | 2.4 | 39.2 | 0 | 2025-06-25 | 0 | 0 | comparative morphology; ITS; ndhF-trnL((UAG)); Philippine violet; pollen; taxonomy | REVISION; REGIONS; POLLEN; GENUS | comparative morphology; ITS; ndhF-trnL<sub>(UAG)</sub>; Philippine violet; pollen; taxonomy | Deccan; Himalayas; India; Western Ghats; angiosperm; comparative study; floral trait; geographical distribution; morphology; morphotype; phylogenetics; taxonomy | English | 2022 | 2022-08 | 10.3390/d14080677 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Network Analysis Using Markov Chain Applied to Wildlife Habitat Selection | In the present study, behavioral states for habitat selection are examined using a discrete-time Markov chain (DTMC) combined with a network model with wildlife movement data. Four male boars (Sus scrofa Linnaeus) at the Bukhansan National Park in South Korea were continuously tracked with an interval of approximately 2 h to 313 days from June 2018 to May 2019. The time-series movement positions were matched with covariates of environmental factors (leaf types and water) in field conditions. Stationary probabilities were used to quantify the habitat selection preference of wild boars, including maximum probability (0.714) with the "broadleaf without water habitat" where in-degree centrality was at its maximum (0.54), but out-degree centrality was low and even (0.17) for all states. Betweenness was the maximum for the "needleleaf without water habitat", suggesting its role as a bridging habitat between other habitats. Out-closeness scores presented the highest values in the "broadleaf without water habitat" (0.26). Similarly, the first hitting time to the habitat was shortest at the "broadleaf without water habitat" (3.64-5.16 h) and slightly longer than one day in other examined habitats, including "broadleaf with water," "needleleaf without water," and "no-leaf without water". The network model using the Markov chain provided information on both local movement behavior and general resource-use patterns of wild boars in field conditions. | Dhakal, Thakur; Lim, Sang-Jin; Park, Yung-Chul; Heo, Muyoung; Lee, Sang-Hee; Hong, Sungwon; Kim, Eui-Kyeong; Chon, Tae-Soo | Kangwon Natl Univ, Inst Forest Sci, Chunchon 24341, South Korea; Yeungnam Univ, Dept Life Sci, Daegu 42415, South Korea; Kangwon Natl Univ, Div Forest Sci, Chunchon 24341, South Korea; Inst for Basic Sci Korea, Infrastruct Operat Team, Daejeon 34126, South Korea; Natl Inst Math Sci, Div Ind Math, Daejeon 34047, South Korea; Kyungpook Natl Univ, Coll Ecol & Environm Sci, Dept Anim Sci & Biotechnol, Sangju 37224, South Korea; Korea Natl Pk Res Inst, Ecol Survey Div, Wonju 26441, South Korea; Ecol & Future Res Inst, Res & Dev, Busan 46228, South Korea | Hong, Sungwon/ADW-3622-2022; Dhakal, Thakur/IUM-7203-2023 | 57197824574; 57193349673; 55494376600; 8207102600; 55917757000; 56431586600; 55551526800; 6701748723 | thakur_dhakal2003@kangwon.ac.kr;sangjin@wrl.re.kr;parky@kangwon.ac.kr;muyoung@gmail.com;sunchaos.sanghee@gmail.com;shong@knu.ac.kr;keuik98@knps.or.kr;tschon.chon@gmail.com; | DIVERSITY-BASEL | DIVERSITY-BASEL | 1424-2818 | 14 | 5 | SCIE | BIODIVERSITY CONSERVATION;ECOLOGY | 2022 | 2.4 | 39.2 | 0.27 | 2025-06-25 | 2 | 2 | wildlife; transition probability; movement; habitat; centrality | ANIMAL BEHAVIOR; MODELS; BOAR; SUITABILITY | centrality; habitat; movement; transition probability; wildlife | Bukhansan National Park; South Korea; behavioral ecology; habitat selection; Markov chain; movement; nature conservation; network analysis; time series analysis; wildlife management | English | 2022 | 2022-05 | 10.3390/d14050330 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Post-Stroke Depression and Cognitive Aging: A Multicenter, Prospective Cohort Study | Background: This study investigated the impact of post-stroke depression (PSD) on cognitive aging in elderly stroke patients. Methods: This study was an interim analysis of the Korean Stroke Cohort for Functioning and Rehabilitation. Among 10,636 patients with first-ever stroke, a total of 3215 patients with normal cognitive function three months post-stroke were included in the analysis. PSD was defined using the Korean Geriatric Depression Scale Short Form (K-GDS-SF) at three months. Cognitive aging was defined as a decline in the Korean version of the Mini-Mental Status Examination (K-MMSE) score to less than the second percentile. Results: The hazard ratio (HR) of PSD for cognitive decline was 2.16 (95% CI, 1.34-3.50, p = 65 years), and 1.02 (95% CI, 0.50-2.07, n.s.) in the younger group (age <65 years). When the older group was divided by sex, the HR was 2.50 (95% CI, 1.26-4.96, p < 0.01) in male patients and 1.80 (95% CI, 0.93-3.51, n.s.) in female patients. However, women showed a higher incidence of cognitive decline in both the PSD and no PSD groups. Among K-GDS-SF factors, "Negative judgment about the past, present, and future" increased the HR of PSD in older male patients. Conclusions: Early PSD increased the HR for cognitive decline in older stroke patients, mainly in males. Specifically, older male patients with negative thinking were at increased risk of cognitive decline. The findings also suggest that older women may be at risk for cognitive decline. Therefore, preventive interventions for cognitive decline should be tailored differently for men and women. | Shin, Minyoung; Sohn, Min Kyun; Lee, Jongmin; Kim, Deog Young; Shin, Yong-Il; Oh, Gyung-Jae; Lee, Yang-Soo; Joo, Min Cheol; Lee, So Young; Song, Min-Keun; Han, Junhee; Ahn, Jeonghoon; Lee, Young-Hoon; Chang, Won Hyuk; Shin, Seyoung; Choi, Soo Mi; Lee, Seon Kui; Kim, Yun-Hee | Sungkyunkwan Univ, Ctr Prevent & Rehabil, Samsung Med Ctr, Heart Vasc Stroke Inst,Sch Med,Dept Phys & Rehabi, Seoul 06351, South Korea; Seoul Grad Sch Counseling Psychol, Dept Counseling Psychol, Seoul 03136, South Korea; Chungnam Natl Univ, Sch Med, Dept Rehabil Med, Daejeon 34134, South Korea; Konkuk Univ, Dept Rehabil Med, Sch Med, Seoul 05030, South Korea; Yonsei Univ, Dept & Res Inst Rehabil Med, Coll Med, Seoul 03722, South Korea; Pusan Natl Univ, Yangsan Hosp, Dept Rehabil Med, Sch Med, Yangsan 46241, South Korea; Wonkwang Univ, Dept Prevent Med, Sch Med, Iksan 51538, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Dept Rehabil Med, Sch Med, Daegu 41566, South Korea; Wonkwang Univ, Dept Rehabil Med, Sch Med, Iksan 51538, South Korea; Jeju Natl Univ, Dept Rehabil Med, Sch Med, Jeju 63243, South Korea; Chonnam Natl Univ, Med Sch, Dept Phys & Rehabil Med, Kwangju 61186, South Korea; Hallym Univ, Dept Stat, Chunchon 24252, South Korea; Ewha Womans Univ, Dept Hlth Convergence, Seoul 03760, South Korea; Korea Dis Control & Prevent Agcy, Div Chron Dis Prevent, Ctr Dis, Cheongju 28159, South Korea; Sungkyunkwan Univ, Samsung Adv Inst Hlth Sci & Technol, Seoul 03063, South Korea | Lee, Jongmin/Q-4909-2019; kim, deog young/Q-8498-2019; Kim, Yun-Hee/GVS-6426-2022; Ahn, Jeonghoon/CAA-1956-2022; Chang, Won Hyuk/I-5662-2015 | 57208747815; 7101840459; 57202882113; 55375583000; 55890990500; 7007056685; 57202952463; 56982599700; 57202327370; 55375416600; 57192890252; 8855402200; 55716155400; 35301717900; 57212192499; 57253230100; 57216396953; 57020121600 | shinminyoung@sgcp.ac.kr;mksohn@cnu.ac.kr;leej@kuh.ac.kr;kimdy@yuhs.ac;rmshin01@gmail.com;pmokj@wku.ac.kr;leeyangsoo@knu.ac.kr;jmc77@hanmail.net;bluelsy900@hanmail.net;drsongmk@daum.net;hanjh@hallym.ac.kr;ahnjeonghoon@ewha.ac.kr;lyh8275@hanmail.net;wh.chang@samsung.com;htl0706@gmail.com;choism7334@korea.kr;byuly74@korea.kr;yun1225.kim@samsung.com; | JOURNAL OF PERSONALIZED MEDICINE | J PERS MED | 2075-4426 | 12 | 3 | SCIE | HEALTH CARE SCIENCES & SERVICES;MEDICINE, GENERAL & INTERNAL | 2022 | 3.4 | 39.2 | 2.03 | 2025-06-25 | 13 | 15 | stroke; post-stroke depression; cognitive decline; dementia; older adults | VASCULAR-DISEASE; STROKE; RISK; ASSOCIATION; IMPAIRMENT; RECOVERY; SYMPTOMS | Cognitive decline; Dementia; Older adults; Post-stroke depression; Stroke | adult; aged; alcohol consumption; arteriovenous malformation; Article; atrial fibrillation; brain hemorrhage; cognitive aging; cohort analysis; computer assisted tomography; diabetes mellitus; female; follow up; Geriatric Depression Scale; heart left ventricle hypertrophy; human; hyperlipidemia; hypertension; intracranial aneurysm; ischemic heart disease; ischemic stroke; longitudinal study; major clinical study; male; moyamoya disease; multicenter study; nuclear magnetic resonance imaging; obesity; peripheral occlusive artery disease; post-stroke depression; Short Portable Mental Status Questionnaire; smoking | English | 2022 | 2022-03 | 10.3390/jpm12030389 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Three-Dimensional Postoperative Results Prediction for Orthognathic Surgery through Deep Learning-Based Alignment Network | To date, for the diagnosis of dentofacial dysmorphosis, we have relied almost entirely on reference points, planes, and angles. This is time consuming, and it is also greatly influenced by the skill level of the practitioner. To solve this problem, we wanted to know if deep neural networks could predict postoperative results of orthognathic surgery without relying on reference points, planes, and angles. We use three-dimensional point cloud data of the skull of 269 patients. The proposed method has two main stages for prediction. In step 1, the skull is divided into six parts through the segmentation network. In step 2, three-dimensional transformation parameters are predicted through the alignment network. The ground truth values of transformation parameters are calculated through the iterative closest points (ICP), which align the preoperative part of skull to the corresponding postoperative part of skull. We compare pointnet, pointnet++ and pointconv for the feature extractor of the alignment network. Moreover, we design a new loss function, which considers the distance error of transformed points for a better accuracy. The accuracy, mean intersection over union (mIoU), and dice coefficient (DC) of the first segmentation network, which divides the upper and lower part of skull, are 0.9998, 0.9994, and 0.9998, respectively. For the second segmentation network, which divides the lower part of skull into 5 parts, they were 0.9949, 0.9900, 0.9949, respectively. The mean absolute error of transverse, anterior-posterior, and vertical distance of part 2 (maxilla) are 0.765 mm, 1.455 mm, and 1.392 mm, respectively. For part 3 (mandible), they were 1.069 mm, 1.831 mm, and 1.375 mm, respectively, and for part 4 (chin), they were 1.913 mm, 2.340 mm, and 1.257 mm, respectively. From this study, postoperative results can now be easily predicted by simply entering the point cloud data of computed tomography. | Jeong, Seung Hyun; Woo, Min Woo; Shin, Dong Sun; Yeom, Han Gyeol; Lim, Hun Jun; Kim, Bong Chul; Yun, Jong Pil | Korea Inst Ind Technol KITECH, Adv Mechatron R&D Grp, Gyongsan 38408, South Korea; Kyungpook Natl Univ, Sch Comp Sci & Engn, Daegu 41566, South Korea; Wonkwang Univ, Daejeon Dent Hosp, Coll Dent, Dept Oral & Maxillofacial Surg, Daejeon 35233, South Korea; Wonkwang Univ, Daejeon Dent Hosp, Coll Dent, Dept Oral & Maxillofacial Radiol, Daejeon 35233, South Korea; Univ Sci & Technol, KITECH Sch, Daejeon 34113, South Korea | Kim, Bong/ABB-3866-2020 | 57219224526; 57297761400; 24482413100; 57208645237; 56060726800; 55578739400; 16644164300 | shjeong@kitech.re.kr;wmw@kitech.re.kr;sdssoft@gmail.com;hangyeo11214@gmail.com;hun216@wku.ac.kr;bck@wku.ac.kr;rebirth@kitech.re.kr; | JOURNAL OF PERSONALIZED MEDICINE | J PERS MED | 2075-4426 | 12 | 6 | SCIE | HEALTH CARE SCIENCES & SERVICES;MEDICINE, GENERAL & INTERNAL | 2022 | 3.4 | 39.2 | 0.95 | 2025-06-25 | 9 | 7 | deep learning; dentofacial deformities; orthognathic surgery; CT X-ray | CT X-ray; deep learning; dentofacial deformities; orthognathic surgery | accuracy; alignment network; Article; artificial neural network; clinical outcome; computer assisted tomography; deep learning; deep neural network; dentofacial deformity; distance error; dual source computer assisted tomography; error; human; iterative closest point; jaw alignment; orthognathic surgery; three dimensional postoperative result; x-ray computed tomography | English | 2022 | 2022-06 | 10.3390/jpm12060998 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Evolution of fracture networks and connectivity during fault-bend folding: Insights from the Sinon Anticline in the southwestern Hongseong-Imjingang Belt, Korea | Crustal shortening in an elastico-frictional regime is mainly accommodated by contractional fault-fold systems with fracture networks. According to recent research, fracture networks in fold-thrust belts express complex internal strain states in response to thrusting and related folding. Furthermore, their connectivity and fluid flow characteristics likely depend on the structural positions and mechanical stratigraphy that control heterogeneous deformation processes. This study provides characteristics of fold-related fracture networks in the Sinon Anti-cline, which was formed by fault-bend folding in the southwestern Hongseong-Imjingang Belt, Korea. The fracture networks in the metamorphosed turbidites characterized by interbedded competent metasandstone layers and relatively thin incompetent schist layers have evolved through pre-, syn-, and post-folding fracturing events. Their complexity reflects the spatiotemporal variation in the strain pattern related to early layer-parallel shortening and subsequent fault-bend folding. Based on insights from detailed mapping and topological analysis of the fracture network, we conclude that strain partitioning that occurs during flexural folding results in a superposed tangential longitudinal strain expressed by fractures with a high (hydraulic) connectivity in the hinge zones. Strain partitioning is caused by flexural interlayer slip along incompetent schist layers in the fold limbs. Bed-parallel slip localization zones probably have low porosity and permeability and may act as barriers to fluid migration across beds. We suggest that heterogeneous vertical axis rotation, which occurred as the system's hanging wall slid over the footwall ramp, increased the complexity of fracture networks within the Sinon Anticline. Our findings indicate that the evolution, connectivity, and fluid flow properties of fracture networks can be characterized through careful interpretation of folding mechanisms and related strain states during for-mation of fault-bend fold systems. | Kim, Inho; Park, Seung-Ik; Kwon, Sanghoon; Lee, Hong-Jin | Kyungpook Natl Univ, Dept Geol, Daegu 41566, South Korea; Yonsei Univ, Dept Earth Syst Sci, Seoul 03722, South Korea; Korea Inst Geosci & Mineral Resources, Geosci Platform Div, Daejeon 34132, South Korea | 57208922381; 55832472000; 7402624141; 57190282574 | psi@knu.ac.kr; | JOURNAL OF STRUCTURAL GEOLOGY | J STRUCT GEOL | 0191-8141 | 1873-1201 | 155 | SCIE | GEOSCIENCES, MULTIDISCIPLINARY | 2022 | 3.1 | 39.4 | 1.39 | 2025-06-25 | 11 | 11 | Fracture network; Fracture connectivity; Fault -bend fold; Flexure; Strain partitioning | PALEOZOIC TAEAN FORMATION; WESTERN GYEONGGI MASSIF; THRUST BELT; SOUTH-KOREA; FLUID-FLOW; MECHANICAL STRATIGRAPHY; METAMORPHIC EVOLUTION; KINEMATIC EVOLUTION; TECTONIC EVOLUTION; GROUNDWATER-FLOW | Fault–bend fold; Flexure; Fracture connectivity; Fracture network; Strain partitioning | Hongseong; Imjingang Belt; South Chungcheong; South Korea; Complex networks; Flow of fluids; Strain; Stratigraphy; Topology; Crustal shortening; Fault bends; Fault–bend fold; Flexure; Foldings; Fracture connectivity; Fracture network; Recent researches; Strain partitioning; Strain state; anticline; complexity; crustal shortening; deformation mechanism; fault zone; flexure; fold belt; folding; fracture network; strain partitioning; strain rate; tectonic evolution; Fracture | English | 2022 | 2022-02 | 10.1016/j.jsg.2021.104506 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
