| ○ | ○ | Article | Prunus mume Seed Exhibits Inhibitory Effect on Skin Senescence via SIRT1 and MMP-1 Regulation | The Prunus mume seed is a by-product of the food industry, and we studied its potential as a food biomaterial, particularly for nutraceutical and inner beauty products. Alternative animal tests showed that an extract of P. mume ripened seed (PmRS) was not toxic on the skin. PmRS exhibited protective effects against ultraviolet- (UV-) induced skin aging in mice, confirmed by phenotypic indications, including increased collagen levels and decreased skin thickness. Compared with the UV-saline group, the UV-PmRS group showed increased levels of silent mating type information regulation 2 homolog 1 (SIRT1) and collagen and decreased matrix metalloproteinase- (MMP-) 1 expression. The protective effect of PmRS treatment against UVB-mediated cell viability was observed in vitro without any cytotoxicity, and PmRS prevented UVB-induced reactive oxygen species generation in HaCaT cells. PmRS downregulated MMP-1 and MMP-13 compared with the UVB-irradiated group. However, mRNA expressions of tissue inhibitor of metalloproteinase-1 and SIRT1 were upregulated by PmRS treatment. MMP-1 and SIRT1 treated with PmRS were decreased and increased, respectively, at the protein level. Moreover, PmRS treatment reduced c-Jun N-terminal kinase and p38 phosphorylation compared with the UVB-treated group. We postulate that P. mume seed could be a useful ingredient in nutraceuticals and inner beauty-purpose foods. | Son, Hyeong-U; Choi, Hee-Jeong; Alam, Md Badrul; Jeong, Chae Gyeong; Lee, Hansong, I; Kim, Solomon L.; Zhao, Peijun; Kim, Tae-Ho; Lee, Sang-Han | Kyungpook Natl Univ, Grad Sch, Sch Food Sci & Biotechnol, Daegu 41566, South Korea; Kyungpook Natl Univ, Inner Beauty Antiaging Ctr, Food & Bioind Res Inst, Daegu 41566, South Korea; Univ Southern Calif, Dept Chem, Los Angeles, CA 90089 USA; Henan Agr Univ, Coll Food Sci & Technol, Zhengzhou 450002, Henan, Peoples R China; Kyungpook Natl Univ Hosp, Biomed Res Inst, Daegu 41940, South Korea; knu BnC, Daegu 41566, South Korea | ; Lee, Seung Eun/ABG-1607-2021; Alam, Md Badrul/AAK-7176-2021 | 53881847500; 57201125608; 56706777100; 57200122018; 57201380653; 55504396700; 57191912964; 57206927313; 57221453703 | shwcrystal@naver.com;choi930302@gmail.com;mbalam@knu.ac.kr;jcg1305@naver.com;znzl9011@hanmail.net;kimsolom@usc.edu;uenzyme@163.com;kimth0929@ynu.ac.kr;sang@knu.ac.kr; | OXIDATIVE MEDICINE AND CELLULAR LONGEVITY | OXID MED CELL LONGEV | 1942-0900 | 1942-0994 | 2021 | SCIE | CELL BIOLOGY | 2021 | 7.31 | 28.0 | 0.49 | 2025-07-30 | 9 | 9 | ACYLATED SUCROSES; OXIDATIVE STRESS; FLOWER BUDS; EXPRESSION; METALLOPROTEINASES; IDENTIFICATION; THICKNESS; COLLAGEN; EXTRACT; TISSUE | Cells; Collagen; Control Systems; Food; Phosphorylation; Processing; Seeds; Ultraviolet Radiation; Animals; Humans; Male; Matrix Metalloproteinase 13; Mice; Prunus; Seeds; Sirtuin 1; Skin; Mammals; amygdalin; biological marker; collagen; collagenase 3; food ingredient; interstitial collagenase; messenger RNA; mitogen activated protein kinase; nutraceutical; plant extract; Prunus mume extract; reactive oxygen metabolite; sirtuin 1; stress activated protein kinase; synaptophysin; tissue inhibitor of metalloproteinase 1; unclassified drug; collagenase 3; Mmp13 protein, mouse; sirtuin 1; Beauty products; C-jun N-terminal kinase; Inhibitory effect; Matrix metalloproteinases; Metalloproteinases; Protective effects; Tissue inhibitor; Type information; animal cell; animal experiment; animal model; animal tissue; antioxidant activity; Article; cell viability; controlled study; cutaneous parameters; cytotoxicity; elasticity; food industry; gene expression; in vitro study; male; MAPK signaling; mouse; nonhuman; plant seed; protein phosphorylation; Prunus; Prunus mume; retention time; reverse transcription polymerase chain reaction; senescence; skin; skin surface; skinfold thickness; ultraviolet B radiation; ultraviolet irradiation; ultraviolet radiation; animal; chemistry; drug effect; human; metabolism; plant seed; Prunus; skin; Collagen | English | 2021 | 2021-06-02 | 10.1155/2021/5528795 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Red Ginseng Oil Attenuates Oxidative Stress and Offers Protection against Ultraviolet-Induced Photo Toxicity | Ginseng (Panax ginseng Meyer) is a well-known herbal medicine that has been used for a long time in Korea to treat various diseases. This study investigated the in vitro and in vivo protective effects of red ginseng extract (RGE) and red ginseng oil (RGO). Liver injury was produced in BALB/c mice by 400 mg/kg of acetaminophen intraperitoneal injection. The antioxidant effects of RGE and RGO on the free radicals 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) and 2,2 '-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid (ABTS) were measured. In addition, the hepatoprotective activities of RGE and RGO on liver markers, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), and oxidative stress markers, including superoxide dismutase (SOD), catalase (CAT) enzyme activity, and 8-hydroxy-2-deoxyguanosine (8-OHdG) in serum and histopathological analysis, were evaluated. The protective effect of RGO on UV-induced phototoxicity was also evaluated in Balb/c 3T3 mouse fibroblast cell line. RGE and RGO effectively inhibited the radicals DPPH and ABTS compared with ascorbic acid and trolox, respectively. Moreover, RGE and RGO significantly decreased the liver enzyme (ALT and AST) levels, increased the antioxidant enzyme (SOD and CAT) levels, and decreased the DNA oxidation product (8-OHdG) content in mice serum. RGO also exhibited protective effect against UV irradiation compared with chlorpromazine hydrochloride, a known phototoxic drug, in Balb/c 3T3 cell line. RGE and RGO possess antioxidant and hepatoprotective properties in mice, and RGO exerts nonphototoxic activity in Balb/c 3T3 cells. | Ullah, H. M.

| ○ | ○ | Article | Characterization of Lower Urinary Tract Dysfunction after Thoracic Spinal Cord Injury in Yucatan Minipigs | There is an increasing need to develop approaches that will not only improve the clinical management of neurogenic lower urinary tract dysfunction (NLUTD) after spinal cord injury (SCI), but also advance therapeutic interventions aimed at recovering bladder function. Although pre-clinical research frequently employs rodent SCI models, large animals such as the pig may play an important translational role in facilitating the development of devices or treatments. Therefore, the objective of this study was to develop a urodynamics protocol to characterize NLUTD in a porcine model of SCI. An iterative process to develop the protocol to perform urodynamics in female Yucatan minipigs began with a group of spinally intact, anesthetized pigs. Subsequently, urodynamic studies were performed in a group of awake, lightly restrained pigs, before and after a contusion-compression SCI at the T2 or T9-T11 spinal cord level. Bladder tissue was obtained for histological analysis at the end of the study. All anesthetized pigs had bladders that were acontractile, which resulted in overflow incontinence once capacity was reached. Uninjured, conscious pigs demonstrated appropriate relaxation and contraction of the external urethral sphincter during the voiding phase. SCI pigs demonstrated neurogenic detrusor overactivity and a significantly elevated post-void residual volume. Relative to the control, SCI bladders were heavier and thicker. The developed urodynamics protocol allows for repetitive evaluation of lower urinary tract function in pigs at different time points post-SCI. This technique manifests the potential for using the pig as an intermediary, large animal model for translational studies in NLUTD. | Keung, Martin S.; Streijger, Femke; Herrity, April; Ethridge, Jay; Dougherty, Susan M.; Aslan, Sevda; Webster, Megan; Fisk, Shera; Deegan, Emily G.; Tessier-Cloutier, Basile; Chen, Kuan-Yin N.; Morrison, Charlotte; Okon, Elena B.; Tigchelaar, Seth; Manouchehri, Neda; Kim, Kyoung-Tae; Shortt, Katelyn; So, Kitty; Damaser, Margot S.; Sherwood, Leslie C.; Howland, Dena R.; Boakye, Max; Hubscher, Charles; Stothers, Lynn; Kavanagh, Alex; Kwon, Brian K. | Univ British Columbia, Fac Med, Int Collaborat Repair Discoveries ICORD, Vancouver, BC, Canada; Univ British Columbia, Fac Med, Dept Neurosci, Vancouver, BC, Canada; Univ British Columbia, Fac Med, Dept Pathol & Lab Med, Vancouver, BC, Canada; Univ British Columbia, Fac Med, Dept Urol Sci, Vancouver, BC, Canada; Univ British Columbia, Fac Med, Vancouver Spine Surg Inst, Dept Orthopaed, Vancouver, BC, Canada; Univ Louisville, Kentucky Spinal Cord Injury Res Ctr, Louisville, KY 40292 USA; Univ Louisville, Dept Neurosurg, Louisville, KY 40292 USA; Univ Louisville, Comparat Med Res Unit, Louisville, KY 40292 USA; Univ Louisville, Dept Anat Sci & Neurobiol, Louisville, KY 40292 USA; Kyungpook Natl Univ, Natl Univ Hosp, Sch Med, Dept Neurosurg, Daegu, South Korea; Cleveland Clin, Lerner Res Inst, Biomed Engn Dept, Cleveland, OH 44106 USA; Louis Stokes Cleveland US Dept Vet Affairs Med Ct, Adv Platform Technol Ctr, Cleveland, OH USA; Robley Rex US Dept Vet Affairs Med Ctr, Res Serv, Louisville, KY USA | ; Howland, Dena/NGS-3004-2025; Sherwood, Leslie/HOH-6736-2023; Tessier-Cloutier, Basile/HTO-7213-2023 | 57211480006; 7801420947; 56126026300; 57219783818; 13005850400; 8501936700; 57214916693; 57212741152; 57194042042; 55693826100; 57223281303; 57211480575; 7006410990; 56610817600; 56685312300; 57201369790; 57194105837; 57194112871; 35597484900; 36633334300; 7003562937; 55681646600; 7003264624; 56961992900; 36544774300; 55851635600 | brian.kwon@ubc.ca; | JOURNAL OF NEUROTRAUMA | J NEUROTRAUM | 0897-7151 | 1557-9042 | 38 | 9 | SCIE | CLINICAL NEUROLOGY;CRITICAL CARE MEDICINE;NEUROSCIENCES | 2021 | 4.869 | 28.1 | 0.66 | 2025-07-30 | 7 | 7 | animal model; lower urinary tract; neurogenic bladder; spinal cord injury; urodynamic studies | animal model; lower urinary tract; neurogenic bladder; spinal cord injury; urodynamic studies | Animals; Disease Models, Animal; Female; Spinal Cord Injuries; Swine; Swine, Miniature; Thoracic Vertebrae; Urinary Bladder; Urinary Tract; Urodynamics; anesthesia; animal experiment; animal model; animal tissue; Article; bladder tissue; compression; controlled study; contusion; female; histology; lower urinary tract symptom; micturition; neurogenic bladder; nonhuman; postvoid residual urine volume; spinal cord injury; thoracic spine; urine incontinence; urodynamics; Yucatan micropig; animal; bladder; disease model; injury; innervation; minipig; pathology; pathophysiology; physiology; pig; spinal cord injury; thoracic vertebra; urinary tract | English | 2021 | 2021-05-01 | 10.1089/neu.2020.7404 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Duraplasty in Traumatic Thoracic Spinal Cord Injury: Impact on Spinal Cord Hemodynamics, Tissue Metabolism, Histology, and Behavioral Recovery Using a Porcine Model | After acute traumatic spinal cord injury (SCI), the spinal cord can swell to fill the subarachnoid space and become compressed by the surrounding dura. In a porcine model of SCI, we performed a duraplasty to expand the subarachnoid space around the injured spinal cord and evaluated how this influenced acute intraparenchymal hemodynamic and metabolic responses, in addition to histological and behavioral recovery. Female Yucatan pigs underwent a T10 SCI, with or without duraplasty. Using microsensors implanted into the spinal cord parenchyma, changes in blood flow (Delta SCBF), oxygenation (Delta PO2), and spinal cord pressure (Delta SCP) during and after SCI were monitored, alongside metabolic responses. Behavioral recovery was tested weekly using the Porcine Injury Behavior Scale (PTIBS). Thereafter, spinal cords were harvested for tissue sparing analyses. In both duraplasty and non-animals, the Delta SCP increased similar to 5 mm Hg in the first 6 h post-injury. After this, the SCP appeared to be slightly reduced in the duraplasty animals, although the group differences were not statistically significant after controlling for injury severity in terms of impact force. During the first seven days post-SCI, the Delta SCBF or Delta PO2 values were not different between the duraplasty and control animals. Over 12 weeks, there was no improvement in hindlimb locomotion as assessed by PTIBS scores and no reduction in tissue damage at the injury site in the duraplasty animals. In our porcine model of SCI, duraplasty did not provide any clear evidence of long-term behavioral or tissue sparing benefit after SCI. | Streijger, Femke; Kim, Kyoung-Tae; So, Kitty; Manouchehri, Neda; Shortt, Katelyn; Okon, Elena B.; Morrison, Charlotte; Fong, Allan; Gupta, Rishab; Brown, Aysha Allard; Tigchelaar, Seth; Sun, Jenny; Liu, Ella; Keung, Martin; Daly, Chris D.; Cripton, Peter A.; Sekhon, Mypinder S.; Griesdale, Donald E.; Kwon, Brian K. | Univ British Columbia UBC, Int Collaborat Repair Discoveries, Vancouver, BC, Canada; Kyungpook Natl Univ Hosp, Dept Neurosurg, Daegu, South Korea; Kyungpook Natl Univ, Sch Med, Dept Neurosurg, Daegu, South Korea; Univ British Columbia UBC, Vancouver Spine Surg Inst, Dept Orthopaed, Vancouver, BC, Canada; Univ British Columbia UBC, Sch Biomed Engn & Orthoped, Vancouver, BC, Canada; Vancouver Gen Hosp, Fac Med, Dept Med, Div Crit Care Med, Vancouver, BC, Canada; Vancouver Gen Hosp, Fac Med, Dept Anesthesiol Pharmacol & Therapeut, Div Crit Care Med, Vancouver, BC, Canada | ; Cripton, Peter/AAC-8268-2020; Griesdale, Donald/AAT-7762-2021; Gupta, Rishab/D-2717-2012 | 7801420947; 57201369790; 57194112871; 56685312300; 57194105837; 7006410990; 57211480575; 57201524785; 58266184200; 57329646200; 56610817600; 57211481108; 57211481074; 57211480006; 57330030400; 6603629883; 6603557927; 6506710109; 55851635600 | brian.kwon@ubc.ca; | JOURNAL OF NEUROTRAUMA | J NEUROTRAUM | 0897-7151 | 1557-9042 | 38 | 21 | SCIE | CLINICAL NEUROLOGY;CRITICAL CARE MEDICINE;NEUROSCIENCES | 2021 | 4.869 | 28.1 | 0.85 | 2025-07-30 | 15 | 15 | duraplasty; hemodynamics; pressure; porcine; spinal cord injury | CEREBRAL-BLOOD-FLOW; LASER-DOPPLER FLOWMETRY; EARLY SURGICAL DECOMPRESSION; INTRASPINAL PRESSURE; HYDROGEN CLEARANCE; PERFUSION-PRESSURE; COMPRESSION; CRANIECTOMY; ISCHEMIA; RAT | duraplasty; hemodynamics; porcine; pressure; spinal cord injury | Animals; Behavior, Animal; Disease Models, Animal; Dura Mater; Female; Hemodynamics; Reconstructive Surgical Procedures; Recovery of Function; Spinal Cord Injuries; Swine; Thoracic Vertebrae; animal experiment; animal model; animal tissue; Article; behavior; blood pressure; controlled study; duraplasty; female; hemodynamics; histology; injury severity; locomotion; nonhuman; oxygenation; spinal cord; spinal cord blood flow; spinal cord injury; spinal cord surgery; thoracic spinal cord; tissue metabolism; Yucatan micropig; animal; animal behavior; convalescence; disease model; dura mater; pathology; pathophysiology; pig; reconstructive surgery; spinal cord injury; thoracic vertebra | English | 2021 | 2021-11-01 | 10.1089/neu.2021.0084 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Estimation of Evapotranspiration and Water Requirements of Strawberry Plants in Greenhouses Using Environmental Data | Farmers routinely determine irrigation requirements from visual observations and cultivation experience, but this can lead to under- or over-irrigation. To establish precise irrigation technology for strawberry cultivation, the average daily evapotranspiration and water requirements were estimated according to the environmental data: air temperature and humidity from the center of the greenhouses and solar radiation from outside greenhouses. Makkink FAO24 equations (temperature and cloudiness) were used to estimate the evapotranspiration and water requirements. The temperature equation showed higher correlation coefficients in solar radiation (R-2 = 0.60), evapotranspiration (R-2 = 0.76), and water requirements (R-2 = 0.69) than other tested equations. The daily irrigation, calculated from the estimated evapotranspiration, was 3.8 tons/10a. It is possible to develop a precision irrigation system from estimated evapotranspiration during the winter cultivation of "Seolhyang" strawberries in South Korea. | Jo, Won Jun; Kim, Dong Sub; Sim, Ha Seon; Ahn, Su Ran; Lee, Hye Jin; Moon, Yu Hyun; Woo, Ui Jeong; Kim, Sung Kyeom | Kyungpook Natl Univ, Coll Agr & Life Sci, Dept Hort Sci, Daegu, South Korea; Univ Calif Davis, Dept Plant Sci, Salinas, CA USA; Kyungpook Natl Univ, Inst Agr Sci & Technol, Daegu, South Korea | Kim, Dong/G-7392-2017; Kim, Sung Kyeom/AAD-9230-2019 | 57219474538; 15760138600; 57220890640; 57220895028; 57900161200; 57226272477; 57226269481; 50262290200 | skkim76@knu.ac.kr; | FRONTIERS IN SUSTAINABLE FOOD SYSTEMS | FRONT SUSTAIN FOOD S | 2571-581X | 5 | SCIE | FOOD SCIENCE & TECHNOLOGY | 2021 | 5.005 | 28.1 | 0.26 | 2025-07-30 | 5 | 5 | solar radiation; temperature; cloudiness; Makkink; Seolhyang | CROP EVAPOTRANSPIRATION; PRECISION IRRIGATION; CLIMATE; MODEL | cloudiness; Makkink; Seolhyang; solar radiation; temperature | English | 2021 | 2021-07-06 | 10.3389/fsufs.2021.684808 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||||
| ○ | ○ | Article | Safety verification of genetically modified rice morphology, hereditary nature, and quality | Background The drought environment occurs frequently due to the unpredictable future climate change, and drought has a direct negative impact on crops, such as yield reduction. Drought events are random, frequent, and persistent. Molecular breeding can be used to create drought-tolerant food crops, but the safety of genetically modified (GM) plants must be demonstrated before they can be adopted. In this research, the environmental risk of drought-tolerant GM rice was explored by assessing phenotype and gene flow. Drought resistance genes CaMsrB2 inserted HV8 and HV23 were used as GM rice to analyze the possibility of various agricultural traits and gene flow along with non-GM rice. Results When the traits 1000-grain weight, grain length/width, and yield, were compared with GM rice and non-GM rice, all agricultural traits of GM rice and non-GM rice were the same. In addition, when the germination rate, viviparous germination rate, pulling strength, and bending strength were compared to analyze the possibility of weediness, all characteristic values of GM rice and non-GM rice were the same. Protein, amylose, and moisture, the major nutritional elements of rice, were also the same. Conclusions The results of this research are that GM rice and non-GM rice were the same in all major agricultural traits except for the newly assigned characteristics, and no gene mobility occurred. Therefore, GM rice can be used as a means to solve the food problem in response to the unpredictable era of climate change in the future. | Jeon, Dong Won; Park, Jae-Ryoung; Jang, Yoon-Hee; Kim, Eun-Gyeong; Ryu, Taehun; Kim, Kyung-Min | Kyungpook Natl Univ, Sch Appl Biosci, Div Plant Biosci, Coll Agr & Life Sci, Daegu 41566, South Korea; Kyungpook Natl Univ, Coastal Agr Res Inst, Daegu, South Korea; Rural Dev Adm, Natl Inst Agr Sci, Biosafety Div, Jeonju, South Korea | ; Kim, Kyung-Min Kim/C-7007-2014 | 57224987652; 57211205505; 57219901992; 57221496070; 23477953500; 34868260300 | kkm@knu.ac.kr; | ENVIRONMENTAL SCIENCES EUROPE | ENVIRON SCI EUR | 2190-4707 | 2190-4715 | 33 | 1 | SCIE | ENVIRONMENTAL SCIENCES | 2021 | 5.481 | 28.1 | 0.48 | 2025-07-30 | 8 | 10 | Drought; Rice; Environmental risk; Gene flow; Genetically modified organism; Yield | SULFOXIDE REDUCTASE B2; DROUGHT TOLERANCE; GENE; GM; HYBRIDIZATION; HERBICIDE; CAMSRB2; PLANTS; BAR; L. | Drought; Environmental risk; Gene flow; Genetically modified organism; Rice; Yield | English | 2021 | 2021-12 | 10.1186/s12302-021-00516-9 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Bright white light emission from (Gd³⁺/Dy³⁺) dual doped transparent lithium aluminum borate glasses for W- LED application | The improving optical and luminescence properties of Dy3+ and Gd3+ dual doped lithium aluminum borate glasses with composition 25Li(2)O-5.0Al(2)O(3)-2.5Gd(2)O(3)-(67.5-X)B2O3-XDy2O3 glasses were successfully developed. The as-synthesis composite used conventional melt-quenching processes. All glass samples doped with Dy2O3 show an enhanced emission intensity (photo and radioluminescence spectra) with increasing the concentration of Dy2O3 up to 1.0 mol%, and beyond that, concentration quenching has occurred for all samples. The experi-mental decay times calculated from the decay profiles have been gradually declined with an increase in Dy3+ ion concentration. The chromaticity coordinates (CIE 1931) were located in the white light region of the color chromaticity diagram.

| ○ | Article | Comparative study of Dy³⁺ doped borate glasses on the basis of luminescence and lasing properties for white-light generation | In this work, a comparative study of Dy3+ activated NMgBiBDy and NBaBiBDy glasses is carried out by investigating the luminescence and lasing properties for the application of white-light generation. By using absorption spectra the oscillator strengths [experimental (fexp) and calculated (fcal)] are measured. The small stimulated emission crossection (sigma rms) values show that they are in good agreement with literature as well as confirm the JO theory. The JO intensity parameters confirm the high asymmetry and the covalence around Dy3+ in the titled glasses. The luminescence emission spectra are carried out by fixing the excitation wavelengths at 388 and 453 nm for NBaBiBDy and NMgBiBDy glasses, respectively. The quenching point is determined at 1.0 mol% for both glasses. The asymmetry nature is confirmed by the yellow/blue (Y/B) ratio. By using the luminescence emission spectra, the important Judd Ofelt (JO) parameters [AR, beta rad, o lambda eff, sigma(lambda p)] are measured. The decay time shows decreasing behavior, confirming the resonance and cross-relaxation energy process in the samples. From the decay times data (tau exp, tau cal) the quantum efficiency and non-radiative relaxation for 4F9/2 level are determined. The chromaticity results suggest that these glasses can be exploited for white-light generation. The NMgBiBDy1.0 glass exhibits better luminescence and lasing properties than the NBaBiBDy1.0, promising for laser and whitelight generation. | Zaman, F.; Srisittipokakun, N.; Rooh, G.; Khattak, S.

| ○ | ○ | Article | Design and photophysical investigation of dipyrromethenates coordinated with the boron(III), zinc(II) and cadmium(II) as optical elements | Alkyl-halogen-dipyrromethene (Dpm) ligands coordinated with boron(III), zinc(II), and cadmium(II) were studied experimentally and theoretically to elucidate and compare influence of the coordination centers and halogen substituents ("heavy" atom effect) on observable photophysical properties. Novel and recently published experimental data were summarized and analyzed using quantum-mechanical calculations which revealed specific of the electronic structures and photo-induced dissipations in the molecular complexes. Halogenation of the Dpm difluoroborates (BODIPY) increases the intersystem spin crossing (ISC) and the triplet harvest whereas halogen atoms play no crucial role in fluorescence quenching of the systems with Zn(II) and Cd(II) complexing agents. Low fluorescence intensities of double Dpm moieties coordinated with the transition metal ions are provided by radiationless internal conversion suppressing photoemission with following ISC which is intensified in presence of halogens. BODIPY fluorescence undergoes direct ISC competition and quenching intensity depend on the kind and the number of halogens. | Aksenova, Iuliia V.; Pomogaev, Vladimir; Prokopenko, Aleksandr A.; Antina, Elena V.; Berezin, Mikhail B.; Guseva, Galina B.; Nuraneeva, Ekaterina N.; Kuznetsova, Rimma | Natl Res Tomsk State Univ, Dept Phys, Lab Photophys & Photochem Mol, 36 Lenin Ave, Tomsk 634050, Russia; Kyungpook Natl Univ, Dept Chem, 80 Daehak Ro, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll Nat Sci, Green Nano Mat Res Ctr, 80 Daehak Ro, Daegu 41566, South Korea; RAS, G A Krestov Inst Solut Chem, Lab Phys Chem Solut Macrocycl Compound, 1 Akad Skaya Str, Ivanovo 153045, Russia | Prokopenko, Alexandr/Q-6673-2016; Antina, Elena/JBJ-7590-2023; Kuznetsova, Rimma/E-5291-2014; Guseva, Galina/P-6001-2015; Antina, Elena/P-6054-2015; Pomogaev, Vladimir/E-5049-2014; Berezin, Mikhail/N-7584-2016; Aksenova, Iuliia/E-5167-2014 | 55242207200; 6603016010; 56467823100; 6603668687; 7006172207; 6603840234; 55874753100; 7006908731 | aksenova.iuliia@gmail.com;helperv@gmail.com; | OPTICAL MATERIALS | OPT MATER | 0925-3467 | 1873-1252 | 119 | SCIE | MATERIALS SCIENCE, MULTIDISCIPLINARY;OPTICS | 2021 | 3.754 | 28.2 | 0.25 | 2025-07-30 | 5 | 4 | Dipyrromethene complexes; BODIPY; Photonics; Spectroscopy; Optical oxygen sensor; Photostability; Quantum-mechanical calculations | SPECTRAL-LUMINESCENT PROPERTIES; BODIPY DYES; SELECTIVE DETECTION; FLUORESCENT-PROBE; COMPLEXES; DERIVATIVES; PHOTOSTABILITY; TEMPERATURE; EFFICIENCY; CHEMISTRY | BODIPY; Dipyrromethene complexes; Optical oxygen sensor; Photonics; Photostability; Quantum-mechanical calculations; Spectroscopy | Cadmium compounds; Electronic structure; Metal ions; Photonics; Quantum theory; Quenching; Spectroscopy; Transition metals; Zinc compounds; BODIPY; Dipyrromethene; Dipyrromethene complex; Intersystem; Optical oxygen sensors; Optical-; Photo-stability; Photophysical investigation; Quantum-mechanical calculation; Spin crossings; Fluorescence | English | 2021 | 2021-09 | 10.1016/j.optmat.2021.111321 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | Gd³⁺/Sm³⁺ energy transfer behavior and spectroscopic study of lithium gadolinium magnesium borate for solid state lighting material | We report the luminescence and energy transfer features in (B2O3)(0.55-x)(Li2O)(0.30) (MgO)(0.10)(Gd2O3)(0.05) (Sm2O3)(x) glasses, prepared via melt-quenching rout. By employing the Judd-Ofelt (JO) theory, the spectral parameters such as oscillator strengths, stimulated emission cross-sections, radiative transition probability and branching ratios are evaluated from the absorption and emission spectra. The dipole-dipole interaction as a dominant interaction mechanism is confirmed from Inokuti-Hirayama (IH) model. The luminescent color falls in the orange part of commission International de I'Eclaiage (CIE). The ultra-violet (UV) sensitization of visible emission of Sm3+ is analyzed by the photoluminescence (PL) emission spectra and the lifetime measurement. The Gd: (6)P7/S-2-8(7/2) emission in UV range and the Sm3+:(4)G(5/2) (-6)HJ luminescence at 598 nm were observed upon the excitation of Gd:4f level by lambda(exc) = 275 nm. Moreover, the impact of energy transfer on the donor-acceptor luminescence, quantum efficiency, and donor luminescence decay kinetics are investigated. It is found that efficient orange luminescence originates from Sm3+ emitting centers. These findings show that these as-prepared luminescent glasses are promising in orange LEDs and laser applications. | Ullah, I.; Shah, S.

| ○ | ○ | Article | Luminescence and scintillation properties of Czochralski grown Pr³⁺ doped Li6Y(BO3)3 single crystal | The Li, an alkali orthoborate compound have been synthesized as polycrystalline powders with different doping concentration of P rare-earth as an activator. The transparent single crystal has also been grown in argon atmosphere by the Czochralski method with 1 mol. % of Pr doping element. The grown crystal possesses a monoclinic structure with a space group of P21/c. The crystal has been cut and optically polished to study the luminescence properties with X-ray, UV, alpha-particles, and gamma-ray excitations. The crystal has showed relaxed 4f15d-4f2 emission at 309 nm along with characteristic 4f2-4f2 transition emissions. The UV-Vis-NIR absorbance spectrum has been obtained in the range of 250-2000 nm. Above 300 nm the crystal has showed about 50% transmittance. The Commission International De I'Eclairage (CIE) chromaticity diagram is depicting the change in combined emission colors for different excitation positions. The scintillation properties of the crystal have been studied with gamma-ray from 60Co, alpha-particles from 241Am and moderated thermal neutrons from a252Cf source. The pulse shape discrimination, obtained for gamma-ray, alpha-particles, and moderated thermal neutrons has shown the potential of this scintillator for thermal neutron detection. | Saha, Sudipta; Khan, Arshad; Kim, H.

| ○ | ○ | Article | The effect of concentration of nano CdS/Fe prepared under different conditions on the structural, optical absorption and linear/nonlinear parameters of PVA/PVP polymer blend | Iron doped cadmium sulfiede (Cd0.9Fe0.1S) was prepared using a thermolysis procedure in air and under the flow of nitrogen. 50%PVA/50%PVP polymer blends doped with different contents of CdS/Fe (1, 3, 5, 10 wt%) were formed using the casting procedure. The effect of preparation atmosphere on the formed phases and the crys-tallinity was investigated using Rietveld method. The possibility of integration of the nanofiller CdS/Fe with a different percentage in the blend matrix was also studied using X-ray diffraction technique. The effect of prep-aration conditions of the nanofiller and its concentrations on the absorbance behavior, extinction coefficient, optical conductivity and band gaps of the blend samples was explored in detail. The refractive index value of PVA/PVP blend was increased from 1.05 to 1.19 or 1.2 as it doped with 10% CdS/Fe (air) or CdS/Fe (N-2), respectively. The nonlinear parameters for the PVA/PVP/CdS/Fe (N-2) have nearly fixed values over a wide range of wavelengths. The fluorescence intensity for the PVA/PVP blend was increased as it was doped with 3% CdS/Fe (air) only. The emitted colors from the blends depended on the excitation wavelength, kind and amount of the nanofiller. | Heiba, Zein K.; El-naggar, A. M.; Mohamed, Mohamed Bakr; Kamal, A. M.; Osman, M.

| ○ | ○ | Article | The radioluminescence and photoluminescence behaviour of lithium alumino borate glasses doped with Tb2O3 and Gd2O3 for green luminescence applications | In this study, we developed the luminescence properties of Tb3+ and Gd3+ dual doped 25Li(2)O-5Al(2)O(3)-YGd2O3-(70-Y-Z)B2O3-ZTb(2)O(3) glasses were prepared by a conventional melt-quenching method. As the concentrations of Gd3+ increase, both the radioluminescence and photoluminescence results increase, and then 2.5% Gd3+ doped glass sample under excitation wavelength with 222, 275, 377 nm providing the strong green emission intensity (at 543 nm) due to the optimum concentration happens. Analysis of the Tb LIII-edge XANES spectra data of LABT series glasses have confirmed the presence of Tb3+. The PL band with the highest intensity of Tb3+ ion in this glass is 4.0 mol% as it results from a maximum of both emission and excitation intensity. The experimental decay times calculated from the decay profiles have been observed to be declining gradually from 2.682 to 2.450 ms with the increase in Tb3+ ion concentration. The energy transfer in the borate glass from Gd3+ to Tb3+ is carried out by non-radiative processes with an efficiency close to 59.20%. The synthesized glass exhibit a high potential candidate for green luminescence applications. | Rittisut, W.; Wantana, N.; Ruangtaweep, Y.; Mool-am-kha, P.; Rujirawat, S.; Manyum, P.; Yimnirun, R.; Kidkhunthod, P.; Prasatkhetragarn, A.; Kothan, S.; Kim, H.

| ○ | ○ | Article | TSL kinetic parameters and dosimetric properties of TlAlF 4 crystal grown by Bridgman technique | The non-hygroscopic crystal of TlAlF4 was grown by self seeded vertical Bridgman technique. The crystalline phase was confirmed through powder X-ray diffraction measurement and compared with reference data. The effective atomic number (Z(eff)) of the TlAlF4 compound was calculated about 70.77. The X-ray induced emission spectrum having a very strong luminescence band at 390 nm. Thermally stimulated luminescence (TSL) glow curve measurement shows the peak maximum at 430 K. The kinetic parameters for the main TSL peak were studied using various standard methods. The mean activation energy (E) is calculated to be 0.93 eV and the frequency factor is 4.79 x 10(11) s-(1). The dose response of the sample was studied using X-ray exited luminescence and TSL glow curves. The sample shows good linearity for measured dose range from 17 to 50 R/min. Thermal fading of the sample was checked over a long period of time and also the reusability of the sample was examined. The main TSL peak at high temperature with high sensitivity to ionizing radiation, good consistency in reusability of TSL signals, linear dose response against delivered X-ray doses in a wide dose range and moderate fading effect are some desirable properties of TlAlF4 crystal for considering radiation dosimetric applications. | Daniel, D.

The study participants completed the Korean TEQ, which has a single factor structure and consists of 16 items; responses are scored using a 5-point Likert scale, giving a maximum possible score of 64. Psychometric validation of the questionnaire was performed by exploratory and confirmatory factor analyses and the goodness of fit test. Average variance extracted was calculated to establish convergent validity, and associations between factors and construct reliability were analyzed to establish discriminant validity. Cronbach's alpha values were utilized for reliability analysis. Results A total of 279 students completed and returned the questionnaire (a 96.2% response rate). Participant empathy scores ranged from 20 to 60 (M = 44.6, SD = 7.36). Empathy scores were higher for females than males (p < .05). The cumulative variance of the Korean TEQ was 32%, indicating that its explanatory power was rather weak. Consequently, goodness-of-fit testing was performed on four hypothetical models, among which a three-factorial structure consisting of 14 items demonstrated satisfactory fit indices and explained 55% of the variance. Reliability estimates of the three subscales were also satisfactory (Cronbach's alpha = .71-.81). This three-factorial model was validated by confirmatory factor analysis and demonstrated adequate convergent and discriminant validity. Conclusions This study demonstrated psychometric validation of the Korean TEQ for measuring medical students' empathy. We suggest a modified 14-item model with a three-factorial structure, which demonstrated better psychometric properties than the original scale. | Yeo, Sanghee; Kim, Kyong-Jee | Kyungpook Natl Univ, Sch Med, Dept Med Educ, Daegu, South Korea; Dongguk Univ, Sch Med, Dept Med Educ, 32 Dongguk Ro, Goyang Si 10326, Gyeonggi Do, South Korea | Kim, Kyong-Jee/K-1278-2012 | 23391520800; 35733979300 | kjkim@dongguk.ac.kr; | BMC MEDICAL EDUCATION | BMC MED EDUC | 1472-6920 | 21 | 1 | SSCI;SCIE | EDUCATION & EDUCATIONAL RESEARCH;EDUCATION, SCIENTIFIC DISCIPLINES | 2021 | 3.263 | 28.3 | 1.87 | 2025-07-30 | 23 | 20 | Empathy; Medical student; Psychometrics; Toronto empathy questionnaire | SIMULATED PATIENTS; CONSTRUCT; BURNOUT; GENDER; SCALE | Empathy; Medical student; Psychometrics; Toronto empathy questionnaire | Empathy; Factor Analysis, Statistical; Female; Humans; Male; Psychometrics; Reproducibility of Results; Republic of Korea; Students, Medical; Surveys and Questionnaires; empathy; factor analysis; female; human; male; medical student; psychometry; questionnaire; reproducibility; South Korea | English | 2021 | 2021-02-19 | 10.1186/s12909-021-02561-7 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
