| ○ | ○ | Article | Tailoring the bandgap, magnetic and photocatalytic behavior of CdS:Nd nanoparticles | We report the fabrication of CdS:Nd nanoparticles (NPs) via an economical co-precipitation method, giving adjustable optical, magnetic and photocatalytic behavior of the nanocrystalline CdS by varying the Nd ion doping concentration. The sensible doping of Nd ions into the CdS matrix was confirmed by various structural characterization techniques. Transmission electron microscopy images demonstrated the basic spheroid shape of the nanoparticles, with sizes in the range of 8-10 nm. A doping concentration-dependent redshift was observed in the CdS NP spectra, resulting from the decrease in the bandgap. The M-H curves illustrate that the undoped sample is diamagnetic, the 2 at% Nd sample is ferromagnetic, and the 4 at% Nd sample is superparamagnetic at room temperature. Photocatalytic measurements revealed that the CdS:Nd (4 at%) sample displayed better photocatalytic activity than undoped CdS NPs. As per literature, this could be the first report on the CdS:Nd system and we believed that it will be more beneficial for the further research on the CdS:Nd system. | Poornaprakash, B.; Vattikuti, S.

| ○ | ○ | Article | Tunable room temperature ferromagnetism and optical bandgap of CdS:Er nanoparticles | A semiconductor compound, which portrays ferromagnetism with tunable optical and photoluminescence properties after a sensible doping of suitable dopant, is vital for modern spintronic and luminescent applications. In this sense, we fabricate CdS, Cd0.98Er0.02S, and Cd0.96Er0.04S nanoparticles (NPs) via an inexpensive co-precipitation way. No structural deformation was found in cubic CdS after Er (III) doping. The as-fabricated NPs demonstrated good crystallinity as well as slight changes in sizes varying 3 nm-7 nm. An X-ray photoelectron spectroscopy results confirmed that the impure-free nature of the prepared samples. A decreasing trend in the optical band gap was found by the increase in the doping level. The 1CdS NPs showed diamagnetic character, whereas the Er (III)-doped CdS NPs exhibited frail ferromagnetic character at room temperature, which slightly increased as a function of Er (III) concentration. Based on the literature, this is the initial magnetic report on the CdS:Er system and this will be very informative for the further magnetic investigations on the Er doping. Hence, the tunable optical and ferromagnetic magnetic properties of CdS:Er NPs demonstrated in this work may be beneficial for optoelectronic, solar cell and spintronic applications. | Poornaprakash, B.; Mangiri, Ramanadha; Al-Kheraif, Abdulaziz A.; Divakar, Darshan Devang; Kim, Y.

| ○ | ○ | Article | Robust controller design for systems with probabilistic uncertain parameters using multi-objective genetic programming | Optimal design of controllers without considering uncertainty in the plant dynamics can induce feedback instabilities and lead to obtaining infeasible controllers in practice. This paper presents a multi-objective evolutionary algorithm integrated with Monte Carlo simulations (MCS) to perform the optimal stochastic design of robust controllers for uncertain time-delay systems. Each potential optimal solution represents a controller in the form of a transfer function with the optimal numerator and denominator polynomials. The proposed methodology uses genetic programming to evolve robust controllers. Using GP enables the algorithm to optimize the structure of the controller and tune the parameters in a holistic approach. The proposed methodology employs MCS to apply robust optimization and uses a new adaptive operator to balance exploration and exploitation in the search space. The performance of controllers is assessed in the closed-loop system with respect to three objective functions as (1) minimization of mean integral time absolute error (ITAE), (2) minimization of the standard deviation of ITAE and (3) minimization of maximum control effort. The new methodology is applied to the first-order and second-order systems with dead time. We evaluate the performance of obtained robust controllers with respect to the upper and lower bounds of step responses and control variables. We also perform a post-processing analysis considering load disturbance and external noise; we illustrate the robustness of the designed controllers by cumulative distribution functions of objective functions for different uncertainty levels. We show how the proposed methodology outperforms the state-of-the-art methods in the literature. | Mallipeddi, Rammohan; Gholaminezhad, Iman; Saeedi, Mohammad S.; Assimi, Hirad; Jamali, Ali | Kyungpook Natl Univ, Coll IT, Dept Artificial Intelligence, Daegu 41566, South Korea; Univ Guilan, Fac Mech Engn, Rasht, Iran; Univ Guilan, Dept Mech Engn, Univ Campus 2, Rasht, Iran; Univ Adelaide, Sch Comp Sci, Adelaide, SA 5005, Australia | Saeedi, Mohammad/AFQ-1644-2022; Mallipeddi, Rammohan/AAL-5306-2020; Assimi, Hirad/O-8366-2018; Jamali, Ali/AAX-5841-2020; Assimi, Hirad/B-4931-2016 | 25639919900; 56216242400; 57217681683; 56513974300; 13805822900 | mallipeddi.ram@gmail.com;ali.jamali@guilan.ac.ir; | SOFT COMPUTING | SOFT COMPUT | 1432-7643 | 1433-7479 | 25 | 1 | SCIE | COMPUTER SCIENCE, ARTIFICIAL INTELLIGENCE;COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS | 2021 | 3.732 | 44.5 | 0.24 | 2025-07-30 | 4 | 3 | Genetic programming; Robust controller; Pareto; Monte Carlo simulation; Uncertainty | DIFFERENTIAL EVOLUTION ALGORITHM; REACTIVE POWER DISPATCH; OPTIMIZATION | Genetic programming; Monte Carlo simulation; Pareto; Robust controller; Uncertainty | Closed loop systems; Delay control systems; Distribution functions; Genetic algorithms; Genetic programming; Intelligent systems; Monte Carlo methods; Optimal systems; Polynomials; Robust control; Stochastic systems; Uncertainty analysis; Cumulative distribution function; Denominator polynomials; Integral time absolute errors; Multi objective evolutionary algorithms; Robust controller design; State-of-the-art methods; Uncertain time-delay system; Upper and lower bounds; Controllers | English | 2021 | 2021-01 | 10.1007/s00500-020-05133-x | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Safety and efficacy of everolimus (EVE) plus exemestane (EXE) in postmenopausal women with locally advanced or metastatic breast cancer: final results from EVEREXES | Background This study was conducted to collect clinical safety, tolerability, and efficacy data with the use of everolimus (EVE) combined with exemestane (EXE) in patients with advanced breast cancer (ABC). Methods The EVEREXES trial initiated in 2012, provided early access to the first dual blockade treatment with EVE + EXE in patients with HR+, HER2 - ABC in Asia and other emerging growth countries. Postmenopausal women with HR+, HER2 - ABC who had documented recurrence or progression, following a nonsteroidal aromatase inhibitor therapy, were treated with EVE (10 mg/day) + EXE (25 mg/day) orally. Results A total of 235 patients received >= 1 dose of study medication. At the end of the study, all patients ceased the treatment. Disease progression (66.0%) was the primary reason of discontinuation. The most common AEs (>= 20%) were stomatitis, decreased appetite, hyperglycemia, rash, aspartate aminotransferase increased, anemia, alanine aminotransferase increased, cough, and fatigue. No new safety concerns were identified in the current study. Median progression-free survival (PFS) in the Asian subset was similar to that of the overall population (9.3 months in both groups). Confirmed overall response rate (ORR) was achieved for 19.6% of the patients. Efficacy of EVE + EXE across subgroups (prior CT, line of treatment, and presence of visceral metastases) was maintained. Conclusion The safety and efficacy results from EVEREXES trial are consistent to data previously reported in BOLERO-2. These results support that EVE + EXE could be a viable treatment option for the postmenopausal women with HR+, HER2 - ABC in Asian region. | Im, Young-Hyuck; Karabulut, Bulent; Lee, Keun Seok; Park, Byeong-Woo; Adhav, Aditya; Cinkir, Havva Yesil; Abdel-Razeq, Hikmat; Chang, Yuan-Ching; Aksoy, Sercan; Im, Seock-Ah; Jeong, Joon; Chae, Yeesoo; Bowles, James; Slimane, Khemaies; Xue, Hongling; Kim, Sung-Bae | Sungkyunkwan Univ, Div Hematol Oncol, Dept Med, Samsung Med Ctr,Sch Med, Seoul, South Korea; Ege Univ, Dept Med Oncol, Fac Med, Izmir, Turkey; Natl Canc Ctr, Ctr Breast Canc, Gyeonggi Do, South Korea; Yonsei Univ Hlth Syst, Dept Surg, Severance Hosp, Seoul, South Korea; HCG Manavata Canc Ctr, Dept Surg Oncol, Nasik, India; Gaziantep Univ, Dept Med Oncol, Med Fac, Gaziantep, Turkey; King Hussein Canc Ctr, Amman, Jordan; Mackay Mem Hosp, Taipei, Taiwan; Hacettepe Univ, Med Fac, Ankara, Turkey; Seoul Natl Univ, Coll Med, Canc Res Inst, Seoul Natl Univ Hosp, Seoul, South Korea; Yonsei Univ Hlth Syst, Gangnam Severance Hosp, Dept Surg, Seoul, South Korea; Kyungpook Natl Univ Hosp, Daegu, South Korea; Novartis Pharma AG, Basel, Switzerland; Novartis Asia Pacific Pharmaceut Pte Ltd, Singapore, Singapore; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Oncol, Seoul, South Korea | Kim, Sung-Bae/JXL-8219-2024; Im, Seock-Ah/J-5620-2012; Aksoy, Sercan/S-2480-2019; Park, Joonhong/AAZ-9885-2020 | 7103344010; 6603897212; 17137276100; 7402834528; 57207776183; 55925639100; 6602398256; 7501844206; 7006512389; 34570185300; 55184774900; 57190793908; 57222495559; 6603436777; 57222488823; 34770722200 | imyh00@skku.edu; | BREAST CANCER RESEARCH AND TREATMENT | BREAST CANCER RES TR | 0167-6806 | 1573-7217 | 188 | 1 | SCIE | ONCOLOGY | 2021 | 4.624 | 44.7 | 0.83 | 2025-07-30 | 12 | 14 | EVEREXES; Breast Cancer; Everolimus; Exemestane; HR  +  HER2  −   Mammalian target of rapamycin (mTOR) | Breast Cancer; EVEREXES; Everolimus; Exemestane; HER2 −; HR +; Mammalian target of rapamycin (mTOR) | Androstadienes; Antineoplastic Combined Chemotherapy Protocols; Asia; Breast Neoplasms; Everolimus; Female; Humans; Neoplasm Recurrence, Local; Postmenopause; Receptor, ErbB-2; Sirolimus; everolimus; exemestane; mammalian target of rapamycin; androstane derivative; antineoplastic agent; epidermal growth factor receptor 2; everolimus; exemestane; rapamycin; adult; advanced cancer; alanine aminotransferase blood level; anemia; aphthous stomatitis; arthralgia; Article; Asia; Asian; aspartate aminotransferase blood level; asthenia; backache; cancer growth; cancer recurrence; coughing; decreased appetite; diarrhea; drug efficacy; drug safety; drug tolerability; dry skin; dysgeusia; dyslipidemia; dyspepsia; dyspnea; endocrine disease; epistaxis; eye disease; fatigue; female; fever; headache; human; hypercholesterolemia; hyperglycemia; hyperlipidemia; hypertriglyceridemia; hypokalemia; hypophosphatemia; insomnia; major clinical study; metastatic breast cancer; middle aged; mouth ulcer; multicenter study; myalgia; nail disease; nausea; open study; peripheral edema; phase 3 clinical trial; pneumonia; postmenopause; productive cough; progression free survival; pruritus; rash; side effect; stomatitis; thrombocytopenia; upper respiratory tract infection; vomiting; breast tumor; postmenopause; tumor recurrence | English | 2021 | 2021-07 | 10.1007/s10549-021-06173-z | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Severe Cutaneous Adverse Reactions to Anti-tuberculosis Drugs in Korean Patients | Purpose: Anti-tuberculosis drugs (ATDs) can cause severe cutaneous adverse reactions (SCARs) such as Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS). Underlying tuberculous infection and co-administration of multiple drugs may contribute to the complexity of ATD-related SCARs. This study aimed to investigate the clinical characteristics and outcomes of ATD-related SCARs. Methods: We analyzed ATD-related SCAR cases in 2010-2015, selected from a web-based Database of the Korean Registry of SCAR. Results: Among 783, 53 patients with ATD-induced SCARs were enrolled, including 12 with SJS/TEN (22.6%) and 41 with DRESS (77.4%). When comparing the ATD and non-ATD groups, the prevalence of DRESS patients was higher in the ATD group than in the non-ATD group (77.4% vs. 45.8%, P< 0.001). Among patients with ATD-related SCARs, those with SJS/TEN were significantly older, had higher intensive care unit admissions, and had higher mortality than those with DRESS (70.5 vs. 50.0 years, P< 0.001; 41.7% vs. 6.1%, P= 0.010; and 33.3% vs. 2.5%, P= 0.003, respectively). ATDs were challenged in 14 cases. The ATD associated most often with SCAR cases was rifampin (81.8%), followed by isoniazid (66.7%), ethambutol (50.0%), pyrazinamide (33.3%). Six patients (42.9%) had hypersensitivity reactions to 2 or more drugs. Conclusions: DRESS was more common among the ATD-related SCAR cases. Although treatment with most ATDs carries the risk of SCAR development, the use of rifampin was most frequently involved in the occurrence of SCARs. Multiple hypersensitivity was frequently observed in ATD-related SCARs. | Jin, Hyun Jung; Kang, Dong Yoon; Nam, Young Hee; Ye, Young Min; Koh, Young-Il; Hur, Gyu-Young; Kim, Sae-Hoon; Yang, Min-Suk; Kim, Sujeong; Jeong, Yi Yeong; Kim, Min-Hye; Choi, Jeong Hee; Kang, Hye-Ryun; Jo, Eun-Jung; Park, Hye-Kyung | Yeungnam Univ, Dept Internal Med, Med Sch, Daegu, South Korea; Seoul Natl Univ Hosp, Drug Safety Monitoring Ctr, Seoul, South Korea; Dong A Univ, Dept Internal Med, Coll Med, Busan, South Korea; Ajou Univ, Dept Allergy & Clin Immunol, Sch Med, Suwon, South Korea; Chonnam Natl Univ Hosp, Dept Internal Med, Gwangju, South Korea; Korea Univ, Dept Internal Med, Coll Med, Seoul, South Korea; Seoul Natl Univ, Dept Internal Med, Bundang Hosp, Seongnam, South Korea; SMG SNU Boramae Med Ctr, Dept Internal Med, Seoul, South Korea; Kyungpook Natl Univ, Sch Med, Dept Internal Med, Daegu, South Korea; Gyeongsang Natl Univ, Gyeongsang Natl Univ Hosp, Dept Internal Med, Coll Med, Jinju, South Korea; Ewha Womans Univ, Coll Med, Dept Internal Med, Seoul, South Korea; Hallym Univ, Dongtan Sacred Heart Hosp, Hwaseong & Allergy & Clin Immunol Res Ctr, Dept Pulmonol & Allergy,Coll Med, Chunchon, South Korea; Seoul Natl Univ, Dept Internal Med, Coll Med, Seoul, South Korea; Pusan Natl Univ, Dept Internal Med, Coll Med, 179 Gudeok Ro, Busan 49241, South Korea | ; Kim, Ju-Hyoung/N-1450-2019; Yang, Min-Suk/GVT-0863-2022; Park, Hye-Kyung/Q-5586-2019; Kim, Sae/AAR-3907-2020; Jin, Hyunjung/MHR-8031-2025 | 36157127500; 37077171700; 37006947800; 13405438300; 58914386100; 7004193730; 35198322400; 7404927140; 36666447400; 7202332057; 58045929900; 7501395695; 7404070922; 55572136700; 57208252986 | parkhk@pusan.ac.kr; | ALLERGY ASTHMA & IMMUNOLOGY RESEARCH | ALLERGY ASTHMA IMMUN | 2092-7355 | 2092-7363 | 13 | 2 | SCIE | ALLERGY;IMMUNOLOGY | 2021 | 5.096 | 44.8 | 1.29 | 2025-07-30 | 23 | 21 | Antitubercular agents; severe cutaneous adverse reactions; Stevens-Johnson syndrome; toxic epidermal necrolysis; drug reaction with eosinophilia and systemic symptoms; drug hypersensitivity syndrome; skin; isoniazid; rifampin | TOXIC EPIDERMAL NECROLYSIS; STEVENS-JOHNSON SYNDROME; INDUCED HYPERSENSITIVITY; ETHAMBUTOL; DIAGNOSIS | Antitubercular agents; Drug hypersensitivity syndrome; Drug reaction with eosinophilia and systemic symptoms; Isoniazid; Rifampin; Severe cutaneous adverse reactions; Skin; Stevens-Johnson syndrome; Toxic epidermal necrolysis | English | 2021 | 2021-03 | 10.4168/aair.2021.13.2.245 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Assessment of the effect on soil microbial communities of genetically modified soybean and a hybrid from crossing with wild soybean | Microbial community analysis of the rhizosphere is one of many approaches for evaluating the environmental impact of genetically modified (GM) crops. To elucidate the influence of GM and hybrid soybeans on the bacterial community of the rhizosphere, this study used a beta-carotene-enhanced transgenic soybean as the GM crop, modified from Kwangan soybean (Glycine max (L.) Merrill), and a hybrid soybean line in which this GM soybean line had been crossed with wild soybean (Glycine soja). Bacterial community analysis indicated that compared to their non-transgenic counterpart, there were no significant effects on the rhizospheres of either the GM or hybrid soybeans. The bacterial densities of the rhizosphere of hybrid and GM soybeans were found to be within the range of those of non-GM soybeans. We found no horizontal gene transfer from GM and hybrid soybeans to soil rhizosphere microorganisms by PCR analysis. Therefore, our results suggest that the impact of GM and hybrid soybeans on the environment, especially on soil microorganisms, is insignificant. | Oh, Sung-Dug; Jang, Ye-Jin; Park, Soo-Yun; Lee, Kijong; Lee, Seong-Kon; Yun, Doh-Won; Suh, Sang Jae; Chae, Jong-Chan | Rural Dev Adm, Natl Inst Agr Sci, Dept Agr Biotechnol, Jeonju 54874, South Korea; Kyungpook Natl Univ, Sch Appl Biosci, Daegu 41566, South Korea; Jeonbuk Natl Univ, Div Biotechnol, Iksan 54596, South Korea; Jeonbuk Natl Univ, Adv Inst Environm & Biosci, Iksan 54596, South Korea | ; Lee, Seong/B-7412-2012 | 7404104129; 55612018200; 45661697500; 57219704626; 37056895800; 7103133449; 15754843200; 7102478062 | chae@jbnu.ac.kr; | PLANT BIOTECHNOLOGY REPORTS | PLANT BIOTECHNOL REP | 1863-5466 | 1863-5474 | 15 | 6 | SCIE | BIOTECHNOLOGY & APPLIED MICROBIOLOGY;PLANT SCIENCES | 2021 | 2.496 | 45.0 | 0.66 | 2025-07-30 | 7 | 8 | Microbial community; GM soybean; Hybrid soybean; Safety of GM crops; Horizontal gene transfer | GLYCINE-MAX L.; GENE-TRANSFER; IDENTIFICATION; TRANSFORMATION; RISKS; DNA | GM soybean; Horizontal gene transfer; Hybrid soybean; Microbial community; Safety of GM crops | English | 2021 | 2021-12 | 10.1007/s11816-021-00710-4 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Importance of Serum Ferritin Level for Early Diagnosis and Differentiation in Patients with Kawasaki Disease with Macrophage Activation Syndrome | We aimed to evaluate the utility of the serum ferritin level as an early screening test of Kawasaki disease with macrophage activation syndrome (KD-MAS). We analyzed the serum ferritin levels on the first day of admission and the clinical progress of patients diagnosed with complete or incomplete KD. Of the 158 patients, 5 were diagnosed with KD-MAS. Conjunctival injection was significantly more frequent in KD group (p = 0.035), although there were no significant differences in other clinical features. On the first day of admission, the serum ferritin level in the KD-MAS group was >500 ng/mL, which was higher than that in the KD group (p = 0.001). In the KD-MAS group, total bilirubin, triglyceride, and lactate dehydrogenase (LDH) were significantly higher, and erythrocyte sedimentation rate (ESR), total protein, albumin, and fibrinogen were significantly lower than the KD group (p < 0.05). Four patients were diagnosed with MAS within 7 days after admission, and 4 (80%) patients with KD-MAS survived. In conclusion, carrying out an early ferritin screening test is important in patients with principal clinical features that may suspect KD. We propose to include ferritin level in the primary laboratory test to differentiate between KD with and without MAS early. | Roh, Da Eun; Kwon, Jung Eun; Choi, Hee Joung; Kim, Yeo Hyang | Kyungpook Natl Univ, Sch Med, Dept Pediat, Daegu 41405, South Korea; Kyungpook Natl Univ, Childrens Hosp, Div Pediat Cardiol, Daegu 41404, South Korea; Keimyung Univ, Sch Med, Dongsan Hosp, Dept Pediat, Daegu 42601, South Korea | 57195734230; 57194002366; 25937150300; 57032023800 | ponyks1004@naver.com;lovecello623@gmail.com;joung-756@hanmail.net;kimyhmd@knu.ac.kr; | CHILDREN-BASEL | CHILDREN-BASEL | 2227-9067 | 8 | 4 | SCIE | PEDIATRICS | 2021 | 2.835 | 45.0 | 1.24 | 2025-07-30 | 9 | 10 | ferritin; fever; kawasaki disease; macrophage activation syndrome | Ferritin; Fever; Kawasaki disease; Macrophage activation syndrome | alanine aminotransferase; albumin; amino terminal pro brain natriuretic peptide; aspartate aminotransferase; bilirubin; C reactive protein; ferritin; fibrinogen; lactate dehydrogenase; triacylglycerol; adolescent; adult; alanine aminotransferase blood level; albumin blood level; Article; aspartate aminotransferase blood level; bilirubin blood level; clinical feature; controlled study; differential diagnosis; early diagnosis; echocardiography; erythrocyte sedimentation rate; female; ferritin blood level; fibrinogen blood level; hemoglobin blood level; hospital admission; human; human cell; laboratory test; lactate dehydrogenase blood level; leukocyte count; macrophage activation syndrome; major clinical study; male; mucocutaneous lymph node syndrome; neutrophil percentage; platelet count; prospective study; protein analysis; triacylglycerol blood level; university hospital | English | 2021 | 2021-04 | 10.3390/children8040269 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Longitudinal Changes in Serum Creatinine Levels and Urinary Biomarkers in Late Preterm Infants during the First Postnatal Week: Association with Acute Kidney Injury and Treatment with Aminoglycoside | We aimed to determine the incidence of acute kidney injury (AKI) and longitudinal changes in SCr levels and urinary biomarkers associated with AKI and aminoglycoside (AG) medication during the first week of life of late preterm infants. Urine biomarkers and SCr were measured in thirty late preterm infants on days one, two, five, and seven postnatal. Urine biomarkers included neutrophil gelatinase-associated lipocalin (NGAL), monocyte chemotactic protein-1 (MCP-1), epidermal growth factor (EGF), Tamm-Horsfall glycoprotein (THP), and liver fatty-acid-binding protein (L-FABP). Gestational age was positively correlated with SCr levels at birth, but inversely correlated with SCr levels at day five and day seven. Eighteen (60%) infants had stage 1 AKI, and twenty (67%) infants were treated with AGs. Infants with AKI had lower gestational age and lower birth weight than those without AKI. Urinary biomarkers adjusted according to uCr levels in infants with AKI were not statistically different from those in infants without AKI. There were no significant differences in incidence of AKI, and SCr levels during and after cessation of AG treatment. The uMCP-1/Cr ratio at days five and seven was higher in infants treated with AG than in non-treated infants. | Lee, Sang-Yoon; Moon, Jung-Eun; Park, Sook-Hyun | Kyunpook Natl Univ, Sch Med, Dept Pediat, Daegu 41404, South Korea; Kyungpook Natl Univ, Chilgok Hosp, Dept Pediat, Daegu 41404, South Korea | 57224403293; 57205770947; 57194595004 | gguggusy@gmail.com;subuya@hanmail.net;park_sh@knu.ac.kr; | CHILDREN-BASEL | CHILDREN-BASEL | 2227-9067 | 8 | 10 | SCIE | PEDIATRICS | 2021 | 2.835 | 45.0 | 0.31 | 2025-07-30 | 2 | 2 | acute kidney injury; aminoglycoside; urinary biomarkers; serum creatinine | GELATINASE-ASSOCIATED LIPOCALIN; EPIDERMAL-GROWTH-FACTOR; ACUTE-RENAL-FAILURE; GESTATIONAL-AGE; MATURATION; HEALTH; SEX | Acute kidney injury; Aminoglycoside; Serum creatinine; Urinary biomarkers | aminoglycoside; ampicillin; biological marker; creatinine; epidermal growth factor; fatty acid binding protein; gentamicin; monocyte chemotactic protein 1; neutrophil gelatinase associated lipocalin; Tamm Horsfall glycoprotein; acute kidney failure; antibiotic therapy; Article; birth weight; body weight loss; clinical article; clinical assessment; controlled study; correlation analysis; creatinine blood level; disease classification; female; gestational age; human; incidence; infant; longitudinal study; male; outcome assessment; perinatal period; pneumonia; prematurity; sepsis; treatment response; urinalysis | English | 2021 | 2021-10 | 10.3390/children8100896 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Treatment Outcomes of Pediatric Acute Myeloid Leukemia in the Yeungnam Region: A Multicenter Retrospective Study of the Study Alliance of Yeungnam Pediatric Hematology-Oncology (SAYPH) | Acute myeloid leukemia (AML) is the second most common pediatric leukemia, with a survival rate of 70%. In this retrospective study, we evaluated the treatment outcomes of pediatric AML among 144 patients diagnosed between 2000 and 2013. After induction, 80.6% of patients achieved complete remission (CR). The 5-year overall survival (OS) and event-free survival (EFS) rates were 58.8 +/- 4.2% and 49.8 +/- 4.2%, respectively. Based on the response to induction therapy, the 5-year OS was 66.9 +/- 5.7% in patients with CR (p < 0.001). Ninety-nine patients with CR after induction therapy were examined, and their 5-year OS and EFS were 66.4 +/- 4.9% and 56.3 +/- 5.1%, respectively. The 5-year OS rates according to treatment were 59.9 +/- 7.4% in the chemotherapy group and 72.3 +/- 6.3% in the hematopoietic stem cell transplantation (HSCT) group (p = 0.089). The EFS was 50.1 +/- 7.4% in the chemotherapy group and 61.7 +/- 6.9% in the HSCT group (p = 0.098). OS and EFS according to cytogenetics were insignificant. Our findings confirmed that the response to induction treatment was important for survival and HSCT had no significant survival benefits compared with those of chemotherapy. Moreover, many early induction deaths under the age of 2 years were observed. | Lee, Jae Min; Yang, Eu Jeen; Park, Kyung Mi; Lee, Young-Ho; Chueh, Heewon; Hah, Jeong Ok; Park, Ji Kyoung; Lim, Jae Young; Park, Eun Sil; Park, Sang Kyu; Kim, Heung Sik; Shim, Ye Jee; Park, Jeong A.; Choi, Eun Jin; Lee, Kun Soo; Kim, Ji Yoon; Lim, Young Tak | Yeungnam Univ, Dept Pediat, Coll Med, Daegu 42415, South Korea; Pusan Natl Univ, Dept Pediat, Childrens Hosp, Sch Med, Yangsan 50612, South Korea; Hanyang Univ, Coll Med, Dept Pediat, Med Ctr, Seoul 04763, South Korea; Dong A Univ, Coll Med, Dept Pediat, Busan 49201, South Korea; Daegu Fatima Hosp, Dept Pediat, Daegu 41199, South Korea; Inje Univ, Coll Med, Busan Paik Hosp, Dept Pediat, Busan 47392, South Korea; Gyeongsang Natl Univ, Coll Med, Dept Pediat, Jinju 52727, South Korea; Ulsan Univ Hosp, Dept Pediat, Ulsan 44033, South Korea; Keimyung Univ, Sch Med, Daegu Dongsan Hosp, Dept Pediat, Daegu 41931, South Korea; Keimyung Univ, Dongsan Hosp, Dept Pediat, Sch Med, Daegu 42601, South Korea; Inje Univ, Haeundae Paik Hosp, Dept Pediat, Busan 41808, South Korea; Mem Sloan Kettering Canc Ctr, Dept Pediat, Manhattan, KS 10065 USA; Daegu Catholic Univ, Dept Pediat, Med Ctr, Daegu 42472, South Korea; Kyungpook Natl Univ, Sch Med, Dept Pediat, Daegu 41944, South Korea | Lee, Jae Min/H-8475-2013; Lee, Jaewoong/IQS-0514-2023; Lee, Kyung-Yil/AFR-4174-2022; Park, Jung Hoon/CZZ-0090-2022 | 39261799700; 56594276100; 57196342718; 43262250600; 39261421100; 7003942219; 35332704400; 55555512300; 26030635800; 57209835309; 7410134477; 57222517942; 36141994300; 35075812900; 7501501684; 57205408095; 7402565128 | mopic@yu.ac.kr;41sirius@hanmail.net;mayani@hanmail.net;cord@hanyang.ac.kr;caaf80@empal.com;johah@med.yu.ac.kr;pjk4285@hanmail.net;pedneu@gnu.ac.kr;espark@gnu.ac.kr;sangulsan@hanmail.net;kimhs@dsmc.or.kr;yejeeshim@dsmc.or.kr;jeonga95@gmail.com;ejchoi2@cu.ac.kr;kslee@knu.ac.kr;phojyk@gmail.com;limyt@pusan.ac.kr; | CHILDREN-BASEL | CHILDREN-BASEL | 2227-9067 | 8 | 2 | SCIE | PEDIATRICS | 2021 | 2.835 | 45.0 | 0.62 | 2025-07-30 | 4 | 4 | acute myeloid leukemia; hematopoietic stem cell transplantation; prognosis; pediatric; childhood; Korea | CELL TRANSPLANTATION; CHILDREN; SARCOMA; CANCER; TRIAL | Acute myeloid leukemia; Childhood; Hematopoietic stem cell transplantation; Korea; Pediatric; Prognosis | antineoplastic agent; acute myeloid leukemia; Article; cancer mortality; cancer patient; cancer prognosis; cancer survival; child; childhood; clinical outcome; controlled study; cytogenetics; drug response; event free survival; female; hematology; hematopoietic stem cell transplantation; human; human cell; induction chemotherapy; leukemia remission; major clinical study; male; oncology; outcome assessment; overall survival; pediatric patient; preschool child; retrospective study; school child; South Korea; study design; survival rate | English | 2021 | 2021-02 | 10.3390/children8020109 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Carbamazepine biodegradation and volatile fatty acids production by selectively enriched sulfate-reducing bacteria and fermentative acidogenic bacteria | BACKGROUND The micropollutant carbamazepine (CBZ) is persistent and resistant to conventional wastewater treatment. This study investigated the role of fermentative acidogenic bacteria (FAB) and sulfate-reducing bacteria (SRB) for CBZ biodegradation and volatile fatty acid (VFA) production. RESULTS The experimental results demonstrated that CBZ biodegradation, total organic carbon and sulfate removal efficiency reached 46%, 36% and 98%, respectively, after 144 h of operation with VFA production of acetic acid (20.72 mmol L-1), propionic acid (3.67 mmol L-1) and butyric acid (4.90 mmol L-1). However, the acetate fraction decreased from 78% to 70% with a decrease in chemical oxygen demand/sulfate (COD:SO42-) ratios from 1.06 to 0.35, respectively, suggesting that acetate was partially oxidized by SRB under substrate/COD limiting conditions. The biodegradation performance of SRB + FAB was also compared with that of a mixed microbial community (MMC). CONCLUSIONS Upon increasing the initial CBZ concentration from 42.3 to 169.2 mu mol L-1, SRB + FAB exhibited much higher CBZ biodegradation (33%) than MMC (12%). Microbial community analyses confirmed the enrichment of VFA-producing species including phylum Firmicutes (2.4% to 36.8%) and class Clostridia (1.3% to 29.6%). Moreover, aromatic and nitroaromatic compound-degrading bacteria such asEscherichiaandDesulfovibriowere also enriched. This signifies the applicability of SRB + FAB to pharmaceutical pollutant biodegradation in the environment.

| ○ | ○ | Article | Identification of suberosin metabolites in human liver microsomes by high-performance liquid chromatography combined with high-resolution quadrupole-orbitrap mass spectrometer | Suberosin is a natural prenylated coumarin derivative isolated fromCitropsis articulata.It has various pharmacological properties, especially as an anticoagulant, for which it has been used since antiquity. However, its metabolic pathway and metabolites have not yet been studied. Therefore, this study characterizes its metabolic pathway and metabolites in human liver microsomes (HLMs) using high-resolution quadrupole-orbitrap mass spectrometry (HRMS/MS). Eight metabolites (M1-M8) were found, including three monohydroxylated (M1-M3), one hydrated (M4), three dihydroxylated (M5-M7), and one glucuronide conjugate (M8). Furthermore, forms of cytochrome P450 (CYPs) responsible for suberosin metabolism in HLMs were characterized. CYP1A2 was identified as a major enzyme for the production of M1 and M5 metabolites. The M2, M3, and M7 metabolites were predominantly generated by CYP2B6. M8 was the only phase II metabolite, identified as a glucuronide conjugate from either M1 or M2. This glucuronide conjugate may be the only promising metabolite from phase II metabolism. Phase I metabolism, especially hydroxylation, was found to provide a predominant metabolic pathway of suberosin in HLMs. Further studies should be conducted to explore the metabolites, examining their efficacy and their toxicity in an in vivo system. | Paudel, Sanjita; Kim, Younah; Choi, Su Min; Kim, Ju-Hyun; Bae, Jong-Sup; Lee, Taeho; Lee, Sangkyu | Kyungpook Natl Univ, Pharmaceut Sci Res Inst, Coll Pharm, BK21 Plus KNU Multiomics Based Creat Drug Res Tea, Daegu 41566, South Korea; Yeungnam Univ, Coll Pharm, Gyongsan 38541, South Korea | Bae, Jong-Sup/AAU-9724-2020 | 57203320448; 57211893872; 57212768203; 55720031300; 16021543200; 57204032003; 57209046767 | tlee@knu.ac.kr;sangkyu@knu.ac.kr; | JOURNAL OF MASS SPECTROMETRY | J MASS SPECTROM | 1076-5174 | 1096-9888 | 56 | 4 | SCIE | BIOCHEMICAL RESEARCH METHODS;CHEMISTRY, ANALYTICAL;SPECTROSCOPY | 2021 | 2.394 | 45.4 | 0.17 | 2025-07-30 | 2 | 2 | cytochrome P450; human liver microsomes; hydroxylation; metabolic pathway; suberosin metabolism | HUMAN CYTOCHROME-P450 2A6; COUMARIN; ISOXANTHOHUMOL; PRODUCTS | cytochrome P450; human liver microsomes; hydroxylation; metabolic pathway; suberosin metabolism | Chromatography, High Pressure Liquid; Coumarins; Cytochrome P-450 CYP1A2; Cytochrome P-450 Enzyme System; Humans; Hydroxylation; Isomerism; Metabolic Networks and Pathways; Metabolome; Microsomes, Liver; Molecular Conformation; Oxidation-Reduction; Tandem Mass Spectrometry; Biomolecules; Drug products; High performance liquid chromatography; Mass spectrometry; Metabolism; coumarin derivative; cytochrome P450 1A1; cytochrome P450 1A2; cytochrome P450 2A6; cytochrome P450 2B6; cytochrome P450 3A4; cytochrome P450 3A5; drug metabolite; suberosin; unclassified drug; coumarin derivative; CYP1A2 protein, human; cytochrome P450; cytochrome P450 1A2; suberosin; Coumarin derivatives; Cytochrome p450; Glucuronide conjugates; High resolution; Human liver microsomes; Metabolic pathways; Orbitrap mass spectrometries; Pharmacological properties; Article; controlled study; dihydroxylation; drug efficacy; drug hydroxylation; drug identification; drug metabolism; drug structure; electrospray; high resolution quadrupole orbitrap mass spectrometry; human; human tissue; hydration; hydroxylation; in vitro study; in vivo study; liver metabolism; liver microsome; mass spectrometry; phenotype; priority journal; protein expression; retention time; reversed phase liquid chromatography; sulfation; tandem mass spectrometry; ultra performance liquid chromatography; chemistry; conformation; high performance liquid chromatography; isomerism; liver microsome; metabolism; metabolome; oxidation reduction reaction; physiology; Metabolites | English | 2021 | 2021-04 | 10.1002/jms.4623 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Mechanism behind the paper spray chemical ionization phenomenon and the choice of solvent | Paper spray chemical ionization (PSCI) combined with mass spectrometry has been proposed as a sensitive method for the analysis of nonpolar aromatic compounds; however, the mechanism behind PSCI is not well understood. In the present study, the evidence for the occurrence of corona discharge is provided and its mechanism is proposed. Photographs taken with a highly sensitive camera evidently demonstrate the occurrence of corona discharge at the end of the triangular shape tip when a nonpolar solvent such as hexane was used at an applied potential of 6-7 kV. Nevertheless, corona discharge was not observed in the presence of a polar solvent. The occurrence of the corona discharge was attributed to charge accumulation in the dielectric layer generated by the nonpolar solvent on the fibers of the paper tip. Specifically, corona discharge was generated at the tip end when the charge approached a critical threshold. In the presence of a polar solvent, however, the dielectric layer was not generated and, hence, corona discharge was not observed. Based on this information, three nonpolar solvents were selected and their sensitivity for analyzing the phenanthrene and maltene fractions of crude oil was evaluated. Chlorobenzene provided the highest signal abundance; therefore, it was suggested as the optimum solvent for PSCI. Notably, the fundamental understanding of corona discharge in PSCI acquired in this study provides a basis for further improvement of this technique by way of surface modification. | Kim, Hyungjun; Lee, Hyunwoo; Kum, Daesub; Tae, Heungsik; Cha, Sangwon; Kim, Donghwi; Kim, Sunghwan | Kyungpook Natl Univ, Dept Chem, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll IT Engn, Sch Elect Engn, Daegu 41566, South Korea; Dongguk Univ, Dept Chem, Seoul 04620, South Korea; Korea Inst Ocean Sci & Technol, Risk Assessment Res Ctr, Geoje 53201, South Korea; Kyungpook Natl Univ, Mass Spectrometry Convergence Res Ctr, Daegu 41566, South Korea; Kyungpook Natl Univ, Green Nano Mat Res Ctr, Daegu 41566, South Korea | ; Cha, Sangwon/C-6917-2008; Kim, Sunghwan/HKN-9812-2023 | 57218223095; 57218220414; 57202230755; 7006298844; 16052094600; 58839420600; 57203772967 | donghwikim@kiost.ac.kr;sunghwank@knu.ac.kr; | JOURNAL OF MASS SPECTROMETRY | J MASS SPECTROM | 1076-5174 | 1096-9888 | 56 | 4 | SCIE | BIOCHEMICAL RESEARCH METHODS;CHEMISTRY, ANALYTICAL;SPECTROSCOPY | 2021 | 2.394 | 45.4 | 0.17 | 2025-07-30 | 1 | 2 | corona discharge; dielectric constant; dielectric layer; mass spectrometry; paper spray chemical ionization | MASS-SPECTROMETRY; REAL-TIME; MOLECULAR-IONS; DESORPTION; PLASMA; OPTIMIZATION; GENERATION; SAMPLES; TISSUE; DRUGS | corona discharge; dielectric constant; dielectric layer; mass spectrometry; paper spray chemical ionization | Electric corona; Ionization; Mass spectrometry; Petroleum analysis; Polyethylenes; 2 butanol; 2 propanol; alcohol; chlorobenzene; dichloromethane; hexane; petroleum; phenanthrene; solvent; toluene; Applied potentials; Charge accumulation; Chemical ionization; Corona discharges; Critical threshold; Non-polar solvents; Sensitive method; Triangular shapes; Article; dielectric constant; ionization; mass spectrometry; paper chromatography; paper spray chemical ionization; photography; priority journal; surface property; Solvents | English | 2021 | 2021-04 | 10.1002/jms.4602 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
