| ○ | ○ | Article | NUMERICAL RANGE AND POSITIVE BLOCK MATRICES | We obtain several norm and eigenvalue inequalities for positive matrices partitioned into four blocks. The results involve the numerical range W(X) of the off-diagonal block X, especially the distance d from 0 to W(X). A special consequence is an estimate, diamW([(A)(X*) (X)(B)]) - diamW(A + B/2) >= 2d, between the diameters of the numerical ranges for the full matrix and its partial trace. | Bourin, Jean-Christophe; Lee, Eun-Young | Univ Bourgogne Franche Comte, CNRS, Lab Math Besancon, UMR 6623, Besancon, France; Kyungpook Natl Univ, KNU Ctr Nonlinear Dynam, Dept Math, Daegu 702701, South Korea | 6602591041; 55371789400 | jcbourin@univ-fcomte.fr;eylee89@knu.ac.kr; | BULLETIN OF THE AUSTRALIAN MATHEMATICAL SOCIETY | B AUST MATH SOC | 0004-9727 | 1755-1633 | 103 | 1 | SCIE | MATHEMATICS | 2021 | 0.622 | 79.4 | 0.45 | 2025-07-30 | 3 | 3 | numerical range; partitioned matrices; norm inequalities | INEQUALITIES; RADIUS; NORM | norm inequalities.; numerical range; partitioned matrices | English | 2021 | 2021-02 | 10.1017/s0004972720000520 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Nutritional status assessed by the Controlling Nutritional Status (CONUT) score as a predictor of recurrence of urolithiasis | Purpose: We aimed to determine the influence of nutritional status on urinary metabolic abnormalities and stone recurrence in patients with urolithiasis. Materials and Methods: We analyzed data for 464 stone-formers and 464 propensity-score-matched control patients that had been collected between 2003 and 2015. Nutritional status was evaluated by use of the Controlling Nutritional Status (CONUT) score, and patients were placed into two CONUT score categories (0-1 and >= 2). Serum and 24-hour urinary metabolites were evaluated in 464 stone-formers. Kaplan-Meier and multivariate Cox regression analyses were performed to assess the influence of nutritional status on stone recurrence. Stone recurrence was defined as radiographic appearance of new stones during the follow-up period. Results: Stone-formers showed a higher prevalence of poor nutrition (CONUT score >= 2) than did the propensity-score-matched control patients (p<0.001). Stone-formers who had poor nutritional status had significantly lower 24-hour urinary calcium but higher oxalate excretion (each p<0.05). Kaplan-Meier estimates demonstrated that stone-formers with poor nutritional status also experienced stone recurrence more rapidly (log-rank test, p=0.014). Multivariate Cox regression revealed that poor nutritional status was independently associated with stone recurrence (hazard ratio, 1.736; 95% confidence interval, 1.041-2.896; p=0.034). Conclusions: The CONUT score, an easily measured immunonutritional biomarker, is independently associated with a higher risk for stone recurrence in patients with urolithiasis. This implies that not only dietary excess, but also undernourished status, may be associated with aberrations in urine physicochemistry and stone recurrence. | Lee, Hee Youn; Kang, Ho Won; Kim, Kyeong; Ha, Yun-Sok; Kim, Won Tae; Kim, Yong-June; Yun, Seok Joong; Kim, Wun-Jae; Lee, Sang-Cheol | Chungbuk Natl Univ, Coll Med, Chungbuk Natl Univ Hosp, Dept Urol, Cheongju, South Korea; Kyungpook Natl Univ, Kyungpook Natl Univ Chilgok, Sch Med, Dept Urol, Daegu, South Korea | Kim, Yong-June/E-5622-2012; Kim, Sung-Soo/AFP-2188-2022; Lee, Sang/E-4151-2012; Kim, Kyu/E-7814-2012; Kim, Jae-hyung/J-8504-2012 | 57217589965; 35757703900; 57220864860; 35487226400; 57203514393; 26422204800; 16302421300; 8081691400; 57218216917 | lscuro@chungbuk.ac.kr; | INVESTIGATIVE AND CLINICAL UROLOGY | INVESTIG CLIN UROL | 2466-0493 | 2466-054X | 62 | 5 | SCIE | UROLOGY & NEPHROLOGY | 2021 | 1.902 | 79.4 | 0.3 | 2025-07-30 | 3 | 3 | Nutritional status; Recurrence; Urinary calculus | KIDNEY-STONE DISEASE; METABOLIC SYNDROME; OBESITY; PREVENTION; IMPACT | Nutritional status; Recurrence; Urinary calculus | Adolescent; Adult; Aged; Aged, 80 and over; Female; Humans; Male; Middle Aged; Nutritional Status; Prognosis; Recurrence; Retrospective Studies; Urolithiasis; Young Adult; calcium; cholesterol; citric acid; creatinine; oxalic acid; serum albumin; sodium; uric acid; adult; age; Article; blood cell count; body mass; controlled study; controlling nutritional status score; diabetes mellitus; female; follow up; human; hypertension; Kaplan Meier method; lifestyle modification; lymphocyte count; major clinical study; male; middle aged; nutritional status; physical chemistry; prevalence; propensity score; questionnaire; recurrent disease; retrospective study; scoring system; stone formation; urolithiasis; adolescent; aged; prognosis; recurrent disease; urolithiasis; very elderly; young adult | English | 2021 | 2021-09 | 10.4111/icu.20210031 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Prognostic impact of perirenal fat stranding on oncologic outcomes in ureteral urothelial carcinoma | Purpose: Perirenal fat stranding (PRFS) is defined as linear areas of soft-tissue attenuation in the perirenal space that can result from ureteral obstruction. We analyzed the prognostic impact of PRFS on outcomes in patients with ureteral urothelial carcinoma (UC). Materials and Methods: Overall, 126 patients evaluated preoperatively by computerized tomography (CT) scan and diagnosed with ureteral UC following nephroureterectomy between January 2001 and May 2018 were included. We analyzed associations between oncologic outcomes and secondary signs such as hydronephrosis and PRFS. Results: Overall, 68 patients (54.0%) showed PRFS on preoperative CT scans. The patients' mean age was 66.33 +/- 9.49 years. A high pT stage (=T3) was seen in 47 patients (37.3%) and high-grade tumors were seen in 90 patients (71.4%). Lymphovascular invasion (LVI) was seen in 15 patients (11.9%), and 5 (4.0%) were at the pN1 stage. Multivariate Cox analysis showed that cT stage=3, PRFS, pT stage=3, tumor grade, LVI, and pN1 stage were independent prognostic factors of recurrence-free survival (RFS) and cancerspecific survival (CSS) (all p<0.05). Conclusions: PRFS was found to be an independent prognostic factor for RFS and CSS. PRFS is easily detectable in preoperative CT imaging and may be useful for improving the prediction of oncologic outcomes of ureteral UC. Therefore, PRFS along with other important preoperative CT findings can help urologists give preoperative advice to patients with ureteral UC before surgical management. | Chung, Jae-Wook; Lee, Jun Nyung; Park, Kyong Min; Byeon, Kyeong Hyeon; Cheon, Hyejin; Ha, Yun-Sok; Choi, Seock Hwan; Kim, Bum Soo; Kim, Tae-Hwan; Yoo, Eun Sang; Kwon, Tae Gyun; Kim, Hyun Tae | Kyungpook Natl Univ, Sch Med, Dept Urol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Radiol, Daegu, South Korea; Kyungpook Natl Univ, Joint Inst Regenerat Med, Daegu, South Korea | Kim, Soo-Yeon/ADR-9663-2022; Kim, Tae/B-9921-2013 | 35204798500; 16301364600; 57221397109; 57204423048; 59784769500; 35487226400; 9742645500; 57202817150; 57797823600; 7006609239; 15073765400; 55739531300 | urologistk@knu.ac.kr; | INVESTIGATIVE AND CLINICAL UROLOGY | INVESTIG CLIN UROL | 2466-0493 | 2466-054X | 62 | 1 | SCIE | UROLOGY & NEPHROLOGY | 2021 | 1.902 | 79.4 | 0.44 | 2025-07-30 | 4 | 5 | Carcinoma; Survival; Ureter; Urothelium | HYDRONEPHROSIS; CT; LOCATION; KIDNEY; GRADE; SIGNS | Carcinoma; Survival; Ureter; Urothelium | Aged; Blood Vessels; Carcinoma, Transitional Cell; Female; Humans; Intra-Abdominal Fat; Kidney; Lymphatic Vessels; Male; Middle Aged; Neoplasm Grading; Neoplasm Invasiveness; Neoplasm Staging; Nephrectomy; Prognosis; Survival Rate; Tomography, X-Ray Computed; Ureteral Neoplasms; Ureteral Obstruction; adult; aged; Article; cancer prognosis; cancer specific survival; cancer staging; computer assisted tomography; cystoscopy; female; follow up; hospitalization; human; human tissue; hydronephrosis; kidney parenchyma; lymph vessel metastasis; major clinical study; male; neoadjuvant chemotherapy; nephroureterectomy; operation duration; perirenal fat; perirenal fat stranding; recurrence free survival; retrospective study; thorax radiography; transitional cell carcinoma; tumor volume; urine cytology; blood vessel; cancer grading; complication; diagnostic imaging; intra-abdominal fat; kidney; lymph vessel; middle aged; nephrectomy; pathology; prognosis; survival rate; transitional cell carcinoma; tumor invasion; ureter obstruction; ureter tumor; x-ray computed tomography | English | 2021 | 2021-01 | 10.4111/icu.20200125 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | RNA interference mediated suppression of TRPV6 inhibits the progression of prostate cancer in vitro by modulating cathepsin B and MMP9 expression | Purpose: The transient receptor potential vanilloid 6 (TRPV6) channel is overexpressed in prostate cancer and its silencing is known to inhibit the growth of LNCaP cells. However, the role of TRPV6 in the metastasis of prostate cancer cells and its relationship to the invasive markers, matrix metalloproteinase (MMP) and cathepsin B, is unclear. Thus, the present study was focused on understanding these tumor-related processes. Materials and Methods: We performed a wound-healing assay and a Transwell migration and invasion assay to assess the migration and invasion of prostate cancer cells. Western blot analysis was used to measure the expression of cathepsin B, MMP2, and MMP9. Results: TRPV6 siRNA significantly inhibited the proliferation of LNCaP prostate cancer cells. It also significantly attenuated the wound healing and migration capacities of LNCaP cells. Moreover, the invasiveness of LNCaP cells and the expression of MMP9 and cathepsin B in LNCaP cells were also significantly inhibited by TRPV6 siRNA. Conclusions: The results indicate that TRPV6 may promote prostate cancer progression in association with MMP9 and cathepsin B, thereby validating further research into TRPV6 as a useful therapeutic target for local invasion or metastasis of advanced prostate cancer. | Kim, Duk Yoon; Kim, Soon Hee; Yang, Eun Kyoung | Daegu Catholic Univ, Sch Med, Dept Urol, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Physiol, 680 Gukchaebosang Ro, Daegu 41944, South Korea | Kim, Young-Il/ISS-7678-2023 | 8366006700; 57226112831; 7202021111 | ekyang@knu.ac.kr; | INVESTIGATIVE AND CLINICAL UROLOGY | INVESTIG CLIN UROL | 2466-0493 | 2466-054X | 62 | 4 | SCIE | UROLOGY & NEPHROLOGY | 2021 | 1.902 | 79.4 | 1.92 | 2025-07-30 | 13 | 13 | Cathepsin B; Matrix metalloproteinase 9; Prostatic neoplasms; Transient receptor potential cation channel subfamily V member 6 | CELL-PROLIFERATION; CHANNEL TRPV6; INVASION; MIGRATION; GROWTH; CA2+ | Cathepsin B; Matrix metalloproteinase 9; Prostatic neoplasms; Transient receptor potential cation channel subfamily V member 6 | Calcium Channels; Cathepsin B; Cell Line, Tumor; Cell Movement; Cell Proliferation; Humans; Male; Matrix Metalloproteinase 2; Matrix Metalloproteinase 9; Neoplasm Invasiveness; Neoplasm Metastasis; Prostatic Neoplasms; RNA Interference; RNA, Small Interfering; TRPV Cation Channels; androgen receptor; cathepsin B; gelatinase A; gelatinase B; matrix metalloproteinase; small interfering RNA; vanilloid receptor 6; calcium channel; cathepsin B; CTSB protein, human; gelatinase A; gelatinase B; MMP2 protein, human; MMP9 protein, human; small interfering RNA; TRPV6 protein, human; vanilloid receptor; Article; cancer growth; cell cycle arrest; cell invasion; cell migration; cell proliferation; cell viability; colony formation; controlled study; down regulation; DU145 cell line; epithelial mesenchymal transition; gene expression; genetic transfection; household income; human; human cell; in vitro study; LNCaP cell line; male; MTT assay; PC-3 [Human prostate carcinoma] cell line; prostate cancer; protein expression; real time polymerase chain reaction; RNA interference; upregulation; Western blotting; wound healing; wound healing assay; cell motion; genetics; metabolism; metastasis; pathology; prostate tumor; RNA interference; tumor cell line; tumor invasion | English | 2021 | 2021-07 | 10.4111/icu.20200511 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | The prognostic value of the pretreatment serum albumin to globulin ratio for predicting adverse pathology in patients undergoing radical prostatectomy for prostate cancer | Purpose: Few studies have demonstrated the clinical significance of pretreatment serum albumin and globulin in prostate cancer (PCa). This study evaluated the association between the pretreatment albumin to globulin ratio (AGR) and clinicopathologic characteristics of nonmetastatic PCa in a large multicenter setting in Korea. Materials and Methods: This study involved 742 patients with nonmetastatic PCa who underwent radical prostatectomy (RP) in seven institutions between January 2011 and December 2012. The AGR was calculated as follows: albumin/(total protein-albumin). Patients were divided into low and high AGR groups by a cutoff value from a receiver operating characteristic curve analysis. Results: The best cutoff for the AGR was set at 1.53. The area under the curve of the AGR was 0.624 (95% confidence interval, 0.557-0.671; p= pT3) than in those with organ-confined disease (= 8) than did the high AGR group (p=0.016). Furthermore, the AGR was an independent prognostic factor for high pGS (>= 8) and non-organ-confined disease (>= pT3), according to multivariate logistic regression analysis. Conclusions: A low AGR was closely associated with nonconfined disease (>= pT3) and high pGS (>= 8). AGR can be a useful serological marker for predicting adverse pathology in patients with nonmetastatic PCa who undergo RP. | Chung, Jae-Wook; Ha, Yun-Sok; Kim, Sang Won; Park, Seung Chol; Kang, Taek Won; Jeong, Young Beom; Park, Sung-Woo; Park, Jinsung; Yoo, Eun Sang; Kwon, Tae Gyun; Seo, Sung Pil; Kang, Ho Won; Kim, Won Tae; Kim, Yong-June; Lee, Sang-Cheol; Kim, Wun-Jae; Yun, Seok Joong; Kim, Tae-Hwan | Kyungpook Natl Univ, Dept Urol, Sch Med, 807 Hoguk Ro, Doegu 41404, South Korea; Wonkwang Univ, Dept Urol, Sch Med & Hosp, Iksan, South Korea; Chonnam Natl Univ, Chonnam Natl Univ Hosp, Dept Urol, Med Sch, Gwangju, South Korea; Jeonbuk Natl Univ, Dept Urol, Med Sch, Jeonju, South Korea; Pusan Natl Univ, Dept Urol, Yangsan Hosp, Yangsan, South Korea; Eulji Univ, Eulji Univ Hosp, Dept Urol, Sch Med, Daejeon, South Korea; Chungbuk Natl Univ, Dept Urol, Coll Med, Cheonqju, South Korea | Lee, Sang/E-4151-2012; Kim, Jae-hyung/J-8504-2012; Kim, Kyu/E-7814-2012; park, sung woo/JTS-5921-2023; Kim, Yong-June/E-5622-2012 | 35204798500; 35487226400; 57219871166; 8446633800; 36065936000; 7202331941; 57185889000; 56900085500; 7006609239; 15073765400; 56115644100; 35757703900; 57203514393; 26422204800; 57218216917; 8081691400; 16302421300; 57797823600 | doctork@knu.ac.kr; | INVESTIGATIVE AND CLINICAL UROLOGY | INVESTIG CLIN UROL | 2466-0493 | 2466-054X | 62 | 5 | SCIE | UROLOGY & NEPHROLOGY | 2021 | 1.902 | 79.4 | 1.18 | 2025-07-30 | 10 | 12 | Albumin; Globulin; Pathology; Prostate cancer; Prostatectomy | BINDING GLOBULIN; INFLAMMATION; RISK; MORTALITY; MEN | Albumin; Globulin; Pathology; Prostate cancer; Prostatectomy | Aged; Humans; Male; Middle Aged; Postoperative Complications; Predictive Value of Tests; Preoperative Period; Prognosis; Prostatectomy; Prostatic Neoplasms; Retrospective Studies; Serum Albumin; Serum Globulins; albumin; globulin; serum albumin; serum globulin; aged; area under the curve; Article; biochemical recurrence; body mass; bone scintiscanning; cancer prognosis; cancer staging; computer assisted tomography; controlled study; follow up; Gleason score; human; Korea; major clinical study; male; multicenter study; nuclear magnetic resonance imaging; preoperative evaluation; prostate adenocarcinoma; prostate biopsy; prostate cancer; prostate volume; prostatectomy; receiver operating characteristic; sensitivity and specificity; transrectal ultrasonography; tumor volume; adverse event; middle aged; postoperative complication; predictive value; preoperative period; prognosis; prostate tumor; prostatectomy; retrospective study | English | 2021 | 2021-09 | 10.4111/icu.20210105 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Hexa-band pattern reconfigurable antenna with defected ground plane | In this paper, a low-profile, compact hexa-band pattern reconfigurable antenna is presented. The proposed antenna consists of a square patch fed by a microstrip line of 50 omega and a ground plane. The ground is loaded with a pair of the split-ring resonators and two rectangular slots that offer multiband operation and pattern reconfigurability. On the top surface of the antenna, two diodes (D1 and D2) are introduced to control current distribution and to achieve pattern diversity. The antenna operates at 2.4 GHz, 3.8 GHz, 4.35 GHz, 4.7 GHz, 5.5 GHz, and 6.25 GHz, with impedance bandwidth in the range of 1.01% to 4.09%. Depending upon the state of operation, the gain of the proposed reconfigurable antenna varies from 1.90 dBi to 2.82 dBi and pattern tilt of +/- 10 degrees at 3.8 GHz, +/- 45 degrees at 4.35 GHz, +/- 25 degrees at 4.7 GHz, +/- 45 degrees at 5.5 GHz, and +/- 45 degrees at 6.25 GHz is observed. The prospective antenna is fabricated and practical inferences are compared with the simulated results. The experimental outcomes are found in good agreement with the simulated results, which validates the beam steering capability of the antenna. | Singh, Ghanshyam; Kanaujia, Binod Kumar; Pandey, Vijay Kumar; Gangwar, Deepak; Kumar, Sachin | Feroze Gandhi Inst Engn & Technol, Dept Elect & Commun Engn, Raebareli, India; Dr APJ Abdul Kalam Tech Univ, Lucknow, Uttar Pradesh, India; Jawaharlal Nehru Univ, Sch Computat & Integrat Sci, New Delhi, India; Noida Inst Engn & Technol, Dept Elect & Commun Engn, Greater Noida, India; Bharati Vidyapeeths Coll Engn, Dept Elect & Commun Engn, New Delhi, India; Kyungpook Natl Univ, Sch Elect Engn, Daegu, South Korea | SINGH, Dr GHANSHYAM/AAN-6377-2020; Kanaujia, Binod/L-6484-2019; kanaujia, Binod/L-6484-2019; Kumar, Sachin/W-2211-2019; pandey, vijay kumar/MBH-8941-2025; Gangwar, Deepak/I-8876-2019 | 57209819290; 56962785800; 59213310600; 55258945300; 56907994000 | gupta.sachin0708@gmail.com; | INTERNATIONAL JOURNAL OF ELECTRONICS | INT J ELECTRON | 0020-7217 | 1362-3060 | 108 | 11 | SCIE | ENGINEERING, ELECTRICAL & ELECTRONIC | 2021 | 1.457 | 79.5 | 0.56 | 2025-07-30 | 6 | 9 | Compact; pattern diversity; reconfigurable; SRR | Compact; pattern diversity; reconfigurable; SRR | Antenna grounds; Directional patterns (antenna); Electric impedance; Microstrip antennas; Slot antennas; Defected ground plane; Impedance bandwidths; Multi-band operations; Pattern diversity; Reconfigurability; Reconfigurable antenna; Rectangular slots; Split ring resonator; Microwave antennas | English | 2021 | 2021-11-02 | 10.1080/00207217.2020.1870749 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Ultrasonographic findings of pediatric dermoid cyst | Background The precise diagnosis of dermoid cysts, which are usually located deeper than other common cysts, is important because dermoid cysts occasionally recur after incomplete excision. Ultrasonography (US) could give useful preoperative information of dermoid cysts but only a few studies have been conducted on US findings related to dermoid cysts. This study aimed to investigate clinical and US findings on pediatric dermoid cysts. Methods We retrospectively reviewed the medical records, clinical photographs, and US findings of 31 pediatric patients (<= 18 years of age) with histopathologically diagnosed dermoid cysts who visited the Pusan National University Hospital between 2007 and 2016. Results Of the 31 patients, 25 underwent ultrasonography. The mean long diameter, short diameter, and depth of the cysts were 12.7, 9.0, and 3.8 mm, respectively. Sixteen cysts (64%) were ovoid, 23 (92%) showed hypoechogenicity, 20 (80%) showed heterogeneity, 19 (76%) showed well-demarcated outer margins, and all cysts showed positive posterior acoustic enhancement. All cysts extended to the subcutaneous tissue, and 15 (60%) showed a connection with the underlying muscle. Conclusions Ultrasonography may be a useful diagnostic method to visualize the extent and location of the dermoid cyst and make an accurate diagnosis prior to surgical intervention. | Ha, Dae-Lyong; Kim, Tae-Rim; Shin, Kihyuk; Kim, Hoon-Soo; Kim, Byung-Soo; Kim, Moon-Bum; Ko, Hyun-Chang | Pusan Natl Univ, Sch Med, Dept Dermatol, Busan, South Korea; Pusan Natl Univ Hosp, Biomed Res Inst, Busan, South Korea; Pusan Natl Univ, Dept Dermatol, Yangsan Hosp, Yangsan, South Korea; Kyungpook Natl Univ, Sch Med, Dept Dermatol, Daegu, South Korea | Kim, Ko Eun/AER-3267-2022; Ko, Hyun-chang/ABF-7418-2021 | 57201367090; 57773718200; 57218366956; 57206211956; 55726523900; 7406088339; 57202265435 | hcko@pusan.ac.kr; | PEDIATRICS INTERNATIONAL | PEDIATR INT | 1328-8067 | 1442-200X | 63 | 4 | SCIE | PEDIATRICS | 2021 | 1.617 | 79.6 | 0.62 | 2025-07-30 | 2 | 4 | dermoid cyst; ultrasonography | dermoid cyst; ultrasonography | Child; Dermoid Cyst; Humans; Neoplasm Recurrence, Local; Retrospective Studies; Ultrasonography; adolescent; adult; Article; child; clinical article; clinical effectiveness; clinical feature; echography; female; histopathology; human; infant; male; priority journal; retrospective study; teratoma; trend study; tumor localization; tumor volume; university hospital; diagnostic imaging; echography; teratoma; tumor recurrence | English | 2021 | 2021-04 | 10.1111/ped.14408 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Portable particle sorting device based on digital microfluidics utilizing micropillars | With introducing the possibility of early diagnosis through biomarker detection, this method has become important in the field of disease diagnosis. Particle sorting based on conventional digital microfluidics (DMF) mostly employs magnetic beads. In this study, the micropillar-based DMF device confirmed the ability of microbead filtering to detect specific biomarkers. The proposed device was implemented using micro-electromechanical systems, and SU-8 micropillar was realized based on the micro-patterning technology. DMF was able to control droplet movements considering the principle of electrowetting on dielectric. The moving speed of a droplet varied according to the electrode shape and applied voltage. As the droplet moved, the polystyrene bead was sorted corresponding to the interval of the fabricated SU-8 micropillar. | Lee, Jae Yong; Kwon, Soon Yeol; Kim, Seung Deok; Kim, Yu Seong; Jung, Dong Geon; Kong, Seong Ho | Kyungpook Natl Univ, Sch Elect & Elect Engn, Daegu 41566, South Korea; Grad Korea Inst Ind Technol, Daegu 42994, South Korea | 57223374818; 57223360705; 57223370762; 57223373159; 56675241000; 57204537951 | shkong@knu.ac.kr; | JAPANESE JOURNAL OF APPLIED PHYSICS | JPN J APPL PHYS | 0021-4922 | 1347-4065 | 60 | SC | SCIE | PHYSICS, APPLIED | 2021 | 1.491 | 79.8 | 0 | 2025-07-30 | 1 | 0 | digital microfluidics; micropillar; particle sorting; biomarker | ON-A-CHIP; FABRICATION; PLATFORMS | Biomarkers; Diagnosis; Drop formation; Electromechanical devices; MEMS; Screening; Applied voltages; Disease diagnosis; Droplet movement; Electro-wetting on dielectrics; Micro electro mechanical system; Micro patterning; Particle sorting; Polystyrene beads; Digital microfluidics | English | 2021 | 2021-06-01 | 10.35848/1347-4065/abf2d4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Long-term outcomes of adjacent and antagonistic teeth after implant restoration: a focus on patient-related factors | Purpose: To investigate factors affecting the antagonistic and adjacent teeth in patients after implant restoration and prosthetic rehabilitation. Methods: In total, 160 patients who visited Kyungpook National University Dental Hospital for implant surgery, prosthesis placement, and supportive periodontal therapy (SPT) were included in this study. The average follow-up period was 88.06 months, and the maximum was 175 months. Patients' history of smoking, diabetes, hypertension, and osteoporosis was investigated, and panoramic radiographs were taken after surgery and prosthetic treatment. During the follow-up period, extraction and prosthetic/endodontic treatments of the antagonistic and adjacent teeth were analyzed. The statistical analyses were performed using descriptive statistics, the chi-square test, the Fisher exact test, and multiple logistic regression analyses. Results: Treatment was performed on 29.4% of the studied antagonistic teeth with extraction performed in 20.0% and prosthetic treatment in 10.0%. Furthermore, 19.4% of the studied adjacent teeth underwent treatment, of which extraction was performed in 12.5% and prosthetic treatment in 7.5%. The treatment rate for adjacent teeth was 25.3% in smokers, which was higher than that of non-smokers (12.3%) (P = 0.039). Patients who were non-adherent to SPT showed a significantly higher rate (19.6%) of antagonistic prosthetic treatment than did those who were adherent (5.5%) (P = 0.006). Conclusions: Implant restoration can affect the adjacent and antagonistic teeth. Smoking, osteoporosis history, and absence of SPT may be risk factors for the treatment of the adjacent and antagonistic teeth. | Park, Su-Yeon; Kim, Yong-Gun; Suh, Jo-Young; Lee, Du-Hyeong; Lee, Jae-Mok | Kyungpook Natl Univ, Sch Dent, Dept Periodontol, Daegu, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Prosthodont, Daegu, South Korea | 57223154616; 55622694400; 7201514992; 35770948000; 17346330000 | leejm@knu.ac.kr; | JOURNAL OF PERIODONTAL AND IMPLANT SCIENCE | J PERIODONTAL IMPLAN | 2093-2278 | 2093-2286 | 51 | 2 | SCIE | DENTISTRY, ORAL SURGERY & MEDICINE | 2021 | 2.086 | 79.9 | 0.66 | 2025-07-30 | 5 | 5 | Dental implants; Dental prosthesis; Follow-up studies; Patient compliance; Survival; Treatment outcome | SINGLE-TOOTH REPLACEMENT; PERIODONTAL STATUS; DENTAL IMPLANTS; NATURAL TEETH; THERAPY; CARIES; ASSOCIATION; SMOKING; COHORT; ADULTS | Dental implants; Dental prosthesis; Follow-up studies; Patient compliance; Survival; Treatment outcome | English | 2021 | 2021-04 | 10.5051/jpis.2005100255 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Structural Damage Identification with a Tuning-free Hybrid Extended Kalman Filter | As a time domain system identification method, the extended Kalman filter (EKF) has been continuously used for structural damage identification. The performance of the EKF varies greatly depending on the selection of the initial parameters' values and their combinations. In this paper, to improve the convergence performance of the EKF and to overcome the dependence on the setting parameter values, a hybrid extended Kalman filter (HEKF) for structural damage identification is proposed. As significant properties of the EKF, the structural damage identification, global convergence, stability, and robustness of the HEKF are guaranteed by integrating a genetic algorithm and the EKF. The performance of the HEKF in structural damage identification was investigated in experiments with four 3-story steel frame test models, which were designed for four different damage scenarios. | Yun, Da Yo; Hong, Taehoon; Lee, Dong-Eun; Park, Hyo Seon | Yonsei Univ, Dept Architectural Engn, Seoul, South Korea; Kyungpook Natl Univ, Sch Architecture & Civil & Architectural Engn, Daegu, South Korea | ; Yun, Da Yo/JGL-9452-2023; Hong, Taehoon/E-9169-2012 | 57205454679; 57969349700; 56605563300; 55669886900 | hspark@yonsei.ac.kr; | STRUCTURAL ENGINEERING INTERNATIONAL | STRUCT ENG INT | 1016-8664 | 1683-0350 | 31 | 3 | SCIE | CONSTRUCTION & BUILDING TECHNOLOGY;ENGINEERING, CIVIL | 2021 | 1.182 | 80.2 | 0.41 | 2025-07-30 | 7 | 7 | structural damage identification; EKF; damage detection; stiffness estimation; system identification | SYSTEM; OPTIMIZATION; MODEL; STATE; STATISTICS; ALGORITHM; PARAMETER | damage detection; EKF; stiffness estimation; structural damage identification; system identification | Extended Kalman filters; Genetic algorithms; Structural analysis; Time domain analysis; Convergence performance; Different damages; Global conver-gence; Hybrid extended kalman filters; Initial parameter; Setting parameters; Structural damage identification; Time domain system identification; Damage detection | English | 2021 | 2021-07-03 | 10.1080/10168664.2020.1797614 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Combined effects of soy isoflavone and lecithin on bone loss in ovariectomized mice | BACKGROUND/OBJECTIVES: Isoflavones (ISFs) are effective in preventing bone loss, but not effective enough to prevent osteoporosis. Mixtures of soy ISF and lecithin (LCT) were prepared and characterized in an attempt to improve the bone loss. MATERIALS/METHODS: The daidzein (DZ) and genistein (GN) solubility in soy ISF were measured using liquid chromatography-mass spectrometry. The change in the crystalline characteristics of soy ISF in LCT was evaluated using X-ray diffraction analysis. Pharmacokinetic studies were conducted to evaluate and compare ISF bioavailability. Animal studies with ovariectomized (OVX) mice were carried out to estimate the effects on bone loss. The Student's t-test was used to evaluate statistical significance. RESULTS: The solubility of DZ and GN in LCT was 125.6 and 9.7 mg/L, respectively, which were approximately 25 and 7 times higher, respectively, than those in water. The bioavailability determined by the area under the curve of DZ for the oral administration (400 mg/kg) of soy ISF alone and the soy ISF-LCT mixture was 13.19 and 16.09 mu g.h/mL, respectively. The bone mineral density of OVX mice given soy ISF-LCT mixtures at ISF doses of 60 and 100 mg/kg daily was 0.189 +/- 0.020 and 0.194 +/- 0.010 g/mm(3), respectively, whereas that of mice given 100 mg/kg soy ISF was 0.172 +/- 0.028 g/mm(3). The number of osteoclasts per bone perimeter was reduced by the simultaneous administration of soy ISF and LCT. CONCLUSIONS: The effect of preventing bone loss and osteoclast formation by ingesting soy ISF and LCT at the same time was superior to soy ISF alone as the bioavailability of ISF may have been improved by the emulsification and solvation of LCT. These results suggest the possibility of using the combination of soy ISF and LCT to prevent osteoporosis. | Kim, Sang Baek; Assefa, Freshet; Lee, Su Jeong; Park, Eui Kyun; Kim, Sung Soo | Osteon Co Ltd, B316 Daedeok Biz Ctr,17 Techno 4 Ro, Daejeon 34013, South Korea; Kyungpook Natl Univ, Sch Dent, Dept Pathol & Regenerat Med, Daegu 41940, South Korea | Lee, Su-Jeong/AAH-8467-2021; Kim, Seok-Hwan/G-9981-2015 | 57316533700; 57219236123; 57219236074; 37071072400; 57316447700 | hawkeye888@naver.com; | NUTRITION RESEARCH AND PRACTICE | NUTR RES PRACT | 1976-1457 | 2005-6168 | 15 | 5 | SCIE | NUTRITION & DIETETICS | 2021 | 1.992 | 80.6 | 0.16 | 2025-07-30 | 2 | 2 | Isoflavones; lecithin; bone; bone density | MINERAL DENSITY; MENOPAUSAL WOMEN; POSTMENOPAUSAL WOMEN; FATTY-ACIDS; METAANALYSIS; METABOLISM; OMEGA-3; ESTROGEN | Bone; Bone density; Isoflavones; Lecithin | English | 2021 | 2021-10 | 10.4162/nrp.2021.15.5.541 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Efficacy of nobiletin in improving hypercholesterolemia and nonalcoholic fatty liver disease in high-cholesterol diet-fed mice | BACKGROUND/OBJECTIVES: Nobiletin (NOB), a citrus flavonoid, is reported to have beneficial effects on cardiovascular and metabolic health. However, there is limited research investigating the effect of long-term supplementation with low-dose NOB on high-cholesterol diet (HCD)-induced hypercholesterolemia and non-obese nonalcoholic fatty liver disease (NAFLD). Therefore, we investigated the influence of NOB on hypercholesterolemia and NAFLD in HCD-fed mice. SUBJECTS/METHODS: C57BL/6J mice were fed a normal diet (ND) or HCD (35 kcal% fat, 1.25% cholesterol, 0.5% cholic acid) with or without NOB (0.02%) for 20 weeks. RESULTS: HCD feeding markedly reduced the final body weight compared to ND feeding, with no apparent energy intake differences. NOB supplementation suppressed HCD-induced weight loss without altering energy intake. Moreover, NOB significantly decreased the total cholesterol (TC) levels and the low-density lipoprotein (LDL)/very-LDL-cholesterol to TC ratio, and increased the high-density lipoprotein-cholesterol/ TC ratio in plasma, compared to those for HCD feeding alone. The plasma levels of inflammatory and atherosclerosis markers (C-reactive protein, oxidized LDL, interleukin [IL]-1 beta, IL-6, and plasminogen activator inhibitor-1) were significantly lower, whereas those of anti-atherogenic adiponectin and paraoxonase were higher in the NOB-supplemented group than in the HCD control group. Furthermore, NOB significantly decreased liver weight, hepatic cholesterol and triglyceride contents, and lipid droplet accumulation by inhibiting messenger RNA expression of hepatic genes and activity levels of cholesterol synthesis-, esterification-, and fatty acid synthesis-associated enzymes, concomitantly enhancing fatty acid oxidation-related gene expression and enzyme activities. Dietary NOB supplementation may protect against hypercholesterolemia and NAFLD via regulation of hepatic lipid metabolism in HCD-fed mice; these effects are associated with the amelioration of inflammation and reductions in the levels of atherosclerosis-associated cardiovascular markers. CONCLUSIONS: The present study suggests that NOB may serve as a potential therapeutic agent for the treatment of HCD-induced hypercholesterolemia and NAFLD. | Kim, Young-Je; Yoon, Dae Seong; Jung, Un Ju | Kyungpook Natl Univ, Dept Food Sci & Nutr, Daegu 41566, South Korea; Pukyong Natl Univ, Dept Food Sci & Nutr, 45 Yongso Ro, Busan 48513, South Korea | ; Kim, Juewon/ABH-3314-2020 | 55571346800; 57226359863; 7007119425 | jungunju@naver.com; | NUTRITION RESEARCH AND PRACTICE | NUTR RES PRACT | 1976-1457 | 2005-6168 | 15 | 4 | SCIE | NUTRITION & DIETETICS | 2021 | 1.992 | 80.6 | 1.6 | 2025-07-30 | 24 | 22 | Nobiletin; hypercholesterolemia; non-alcoholic fatty liver disease; inflammation | C-REACTIVE PROTEIN; LOW-DENSITY-LIPOPROTEIN; CORONARY-HEART-DISEASE; 3-HYDROXY-3-METHYLGLUTARYL-COA REDUCTASE; ACYL-COENZYME; TISSUE FACTOR; RAT-LIVER; ATHEROSCLEROSIS; ACYLTRANSFERASE; ACAT2 | Hypercholesterolemia; Inflammation; Nobiletin; Non-alcoholic fatty liver disease | English | 2021 | 2021-08 | 10.4162/nrp.2021.15.4.431 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Maternal high-fructose intake during pregnancy and lactation induces metabolic syndrome in adult offspring | BACKGROUND/OBJECTIVES: Nutritional status and food intake during pregnancy and lactation can affect fetal programming. In the current metabolic syndrome epidemic, high-fructose diets have been strongly implicated. This study investigated the effect of maternal high-fructose intake during pregnancy and lactation on the development of metabolic syndrome in adult offspring. SUBJECTS/METHODS: Drinking water with or without 20% fructose was administered to female C57BL/6J mice over the course of their pregnancy and lactation periods. After weaning, pups ate regular chow. Accu-Chek Performa was used to measure glucose levels, and a tail-cuff method was used to examine systolic blood pressure. Animals were sacrificed at 7 months, their livers were excised, and sections were stained with Oil Red O and hematoxylin and eosin (H&E) staining. Kidneys were collected for gene expression analysis using quantitative real-time Polymerase chain reaction. RESULTS: Adult offspring exposed to maternal high-fructose intake during pregnancy and lactation presented with heavier body weights, fattier livers, and broader areas under the curve in glucose tolerance test values than control offspring. Serum levels of alanine aminotransferase, aspartate aminotransferase, glucose, triglycerides, and total cholesterol and systolic blood pressure in the maternal high-fructose group were higher than that in controls. However, there were no significant differences in mRNA expressions of renin-angiotensin-aldosterone system genes and sodium transporter genes. CONCLUSIONS: These results suggest that maternal high-fructose intake during pregnancy and lactation induces metabolic syndrome with hyperglycemia, hypertension, and dyslipidemia in adult offspring. | Koo, Soohyeon; Kim, Mina; Cho, Hyun Min; Kim, Inkyeom | Kyungpook Natl Univ, Sch Med, Dept Pharmacol, 680 GukchaeBosang St, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Cardiovasc Res Inst, Daegu 41944, South Korea; Kyungpook Natl Univ, Sch Med, Dept Biomed Sci, BK21 Plus KNU Biomed Convergence Program, Daegu 41944, South Korea | 57222255070; 57190982374; 57198104843; 7404144630 | inkim@knu.ac.kr; | NUTRITION RESEARCH AND PRACTICE | NUTR RES PRACT | 1976-1457 | 2005-6168 | 15 | 2 | SCIE | NUTRITION & DIETETICS | 2021 | 1.992 | 80.6 | 1.2 | 2025-07-30 | 18 | 17 | Dyslipidemia; hypercholesterolemia; hyperglycemia; hypertension | Dyslipidemia; Hypercholesterolemia; Hyperglycemia; Hypertension | English | 2021 | 2021-04 | 10.4162/nrp.2021.15.2.160 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Nationwide "Pediatric Nutrition Day" survey on the nutritional status of hospitalized children in South Korea | BACKGROUND/OBJECTIVES: To evaluate the nutritional status and prevalence of malnutrition in hospitalized children at admission and during hospitalization in South Korea. SUBJECTS/METHODS: This first cross-sectional nationwide "Pediatric Nutrition Day (pNday)" survey was conducted among 872 hospitalized children (504 boys, 368 girls; 686 medical, 186 surgical) from 23 hospitals in South Korea. Malnutrition risk was screened using the Pediatric Yorkhill Malnutrition Score (PYMS) and the Screening Tool Risk on Nutritional status and Growth. Nutritional status was assessed by z-scores of weight-for-age for underweight, weight-for-height for wasting, and height-for-age for stunting as well as laboratory tests. RESULTS: At admission, of the 872 hospitalized children, 17.2% were underweight, and the prevalence of wasting and stunting was 20.2% and 17.3%, respectively. During hospitalization till pNday, 10.8% and 19.6% experienced weight loss and decreased oral intake, respectively. During the aforementioned period, fasting was more prevalent in surgical patients (7.5%) than in medical patients (1.6%) (P < 0.001). According to the PYMS, 34.3% and 30% of the children at admission and on pNday, respectively, had a high-risk of malnutrition, requiring consultation with the nutritional support team (NST). However, only 4% were actually referred to the NST during hospitalization. CONCLUSIONS: Malnutrition was prevalent at admission and during hospitalization in pediatric patients, with many children experiencing weight loss and poor oral intake. To improve the nutritional status of hospitalized children, it is important to screen and identify all children at risk of malnutrition and refer malnourished patients to the multidisciplinary NST for proper nutritional interventions. | Lee, Yoo Min; Ryoo, Eell; Hong, Jeana; Kang, Ben; Choe, Byung-Ho; Seo, Ji-Hyun; Park, Ji Sook; Jang, Hyo-Jeong; Lee, Yoon; Chang, Eun Jae; Chang, Ju Young; Lee, Hae Jeong; Kim, Ju Young; Lee, Eun Hye; Kim, Hyun Jin; Chung, Ju-Young; Choi, You Jin; Choi, So Yoon; Kim, Soon Chul; Kang, Ki-Soo; Yi, Dae Yong; Moon, Kyung Rye; Lee, Ji Hyuk; Kim, Yong Joo; Yang, Hye Ran | Soonchunhyang Univ, Bucheon Hosp, Dept Pediat, Coll Med, Bucheon 14584, South Korea; Gachon Univ, Coll Med, Dept Pediat, Gil Med Ctr, Incheon 21565, South Korea; Kangwon Natl Univ, Dept Pediat, Sch Med, Chunchon 24289, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pediat, Daegu 41944, South Korea; Gyeongsang Natl Univ, Gyeongsang Natl Univ Hosp, Gyeongsang Natl Inst Hlth Sci, Dept Pediat,Coll Med, Jinju 52727, South Korea; Keimyung Univ, Sch Med, Dept Pediat, Dongsan Med Ctr, Daegu 42601, South Korea; Korea Univ, Dept Pediat, Coll Med, Seoul 02841, South Korea; Hanyang Univ, Myongji Hosp, Dept Pediat, Coll Med, Goyang 10475, South Korea; Seoul Natl Univ, Boramae Med Ctr, Dept Pediat, Seoul 07061, South Korea; Sungkyunkwan Univ, Samsung Changwon Hosp, Dept Pediat, Sch Med, Chang Won 51353, South Korea; Eulji Univ, Daejeon Eulji Med Ctr, Dept Pediat, Sch Med, Daejeon 35233, South Korea; Eulji Univ, Nowon Eulji Med Ctr, Dept Pediat, Sch Med, Seoul 01830, South Korea; Inje Univ, Busan Paik Hosp, Dept Pediat, Coll Med, Busan 47392, South Korea; Inje Univ, Coll Med, Dept Pediat, Sanggye Paik Hosp, Seoul 01757, South Korea; Inje Univ, Coll Med, Dept Pediat, Ilsan Paik Hosp, Goyang 10380, South Korea; Inje Univ, Haeundae Paik Hosp, Dept Pediat, Coll Med, Busan 48108, South Korea; Jeonbuk Natl Univ, Jeonbuk Natl Univ Hosp, Dept Pediat, Med Sch, Jeonju 54907, South Korea; Jeju Natl Univ Hosp, Dept Pediat, Jeju 63241, South Korea; Chung Ang Univ, Chung Ang Univ Hosp, Dept Pediat, Coll Med, Seoul 06973, South Korea; Chosun Univ, Dept Pediat, Sch Med, Gwangju 61453, South Korea; Chungbuk Natl Univ, Dept Pediat, Coll Med, Cheongju 28644, South Korea; Hanyang Univ, Med Ctr, Dept Pediat, Coll Med, Seoul 04763, South Korea; Seoul Natl Univ, Dept Pediat, Bundang Hosp, 82 Gumi Ro 173 Beon Gil, Seongnam 13620, South Korea; Seoul Natl Univ, Dept Pediat, Coll Med, Seoul 08826, South Korea | Kim, Siwon/KHX-9078-2024; 康, 奔/JMQ-0812-2023; Yang, Hye/J-5533-2012; Lee, Yong Jae/GLR-4153-2022; Yi, Dae/G-1729-2014; LEE, HYUN/ABC-6119-2021; Choe, Byung-Ho/KSM-6251-2024; Chang, Ju/J-5631-2012 | 55588928200; 19837506900; 55371401700; 57194823199; 57574977300; 55712045100; 35485228600; 55355948500; 55588945800; 57020640100; 7601549478; 35722209100; 57202996384; 57188855950; 58975661600; 12801178900; 56063619400; 57207282105; 36087407700; 56892514000; 57190851975; 57023001700; 36011672600; 56063569800; 57049781100 | hryang@snubh.org; | NUTRITION RESEARCH AND PRACTICE | NUTR RES PRACT | 1976-1457 | 2005-6168 | 15 | 2 | SCIE | NUTRITION & DIETETICS | 2021 | 1.992 | 80.6 | 0.08 | 2025-07-30 | 2 | 1 | Nutrition surveys; nutritional status; malnutrition; child; hospitalization | SCREENING TOOLS; MALNUTRITION; RISK | Child; Hospitalization; Malnutrition; Nutrition surveys; Nutritional status | English | 2021 | 2021-04 | 10.4162/nrp.2021.15.2.213 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
