| ○ | ○ | Article | Analysis of fluorescence characteristics of Sm³⁺-doped B2O3-rich glasses for Orange-light-emitting diodes | Optical absorption and visible luminescence aspects including visible emission decay times have been examined for six Sm3+ (1 mol%)-doped B2O3-rich glasses comprising single and mixed alkali oxides which were synthesized via melting-and-quenching approach. Upon intense lambda(exci) = 409 nm, fluorescence spectra displayed four bands peaked at 562 nm, 598 nm, 645 nm, and 706 nm owing to (4)G(5/2) upper level to H-6(5/2), H-6(7/2), H-6(9/2), and H-6(11/2) lower levels transitions respectively. Among identified emissions, orange fluorescence (598 nm) is found to be strong in all samples. Moreover Sm3+: Li ions having sample exhibits the dominant visible emissions band intensity in all samples, so for this sample, Judd-Ofelt (J-O) analysis was carried out to calculate J-O parameters Omega(t) (t = 2, 4, 6), and from them, radiative transition probabilities, branching ratios (calculated and experimental), and radiative lifetimes of Sm3+: (4)G(5/2) level to distinct lower energy states were derived utilizing absorption and emission spectra. CIE (Commission Internationale de l'eclairage) coordinates, correlated color temperature (CCT), color purity, color rendering index, and luminous efficiency of radiation were determined from visible luminescence spectra of all studied glasses, and obtained CIE coordinates and CCT values lie in the reddish-orange light region of CIE diagram, indicating their potential for orange LEDs (light-emitting diodes) application. Here derived CCT values are lower than the typical warm light sources CCT limit (<3200 K). (4)G(5/2) state luminescence decay patterns revealed double exponential behavior for assessing the measured lifetimes. Effective bandwidth, stimulated emission cross-section, and gain bandwidth were computed for observed luminescence transitions of Sm3+: Li ions possessing sample. (C) 2021 Elsevier B.V.

| ○ | ○ | Article | Crystal growth, optical, luminescence and scintillation characterization of Li2Zn2(MoO4)3 crystal | A Li2Zn2(MoO4)(3) (LZMO) single crystal was grown by the flux method under the condition of a low temperature-gradient. The obtained crystal has a single-phase confirmed by a powder X-ray diffraction study. Luminescence properties of the crystal have been studied from room to cryogenic (300-6 K) temperatures under excitation by a 280 nm light-emitting diode (LED). At 6 K, the grown crystal exhibits an intrinsic emission band with emission wavelength ranges from 400 to 900 nm, and the maximum peak at similar to 612 nm. From 6 to 280 K, the luminescence decay time of the crystal was studied using the 280 nm LED. The decay times for the entire temperature range were fitted with two exponential decay functions. The temperature-dependent (300-10 K) scintillation light yield was studied under the excitation of a Sr-90 (beta) radioactive source. We compared scintillation and luminescence light yields of the LZMO with a reference CaMoO4 crystal. Thermoluminescence study of the crystal was carried out from 9 to 300 K and different kinematic parameters such as activation energy and frequency factor have been calculated. From this study, it shows that the LZMO crystal has potential as detector material in experiments searching for neutrinoless double-beta decay of Mo-100 at cryogenic temperatures.

| ○ | ○ | Article | Detrimental effects of impurity phases on the thermoelectric performance of Nb0.8Ti0.2Fe1.02Sb synthesized by arc-melting | We demonstrate the detrimental impacts of impurity phases on thermoelectric (TE) performance in Nb0.8Ti0.2Fe1.02Sb system that instigate performance irreproducibility that may impede rapid and pro-gressive performance improvement of compounds synthesized by arc-melting. Three samples prepared by arc-melting are annealed at 700 degrees C, 850 degrees C and 1000 degrees C. The optimal homogeneity is achieved in the sample annealed at 850 degrees C with similar to 0.8% impurity phases' quantity, relative to similar to 4% and similar to 10% in the samples annealed at 700 degrees C and 1000 degrees C, respectively. The samples with increased impurities depict a significantly decreased Seebeck coefficient and increased lattice thermal conductivity, which intimately impairs the TE performance. The highest ZT is achieved in the sample with the least impurities, similar to 0.73 at 873 K, which is 49% higher than the inhomogeneous samples. This stresses the pertinence of minimizing the impurities in a bid to reproduce the optimal TE performance from this system. (C) 2021 Elsevier B.V.

| ○ | ○ | Article | Enhanced output power of thermoelectric modules with reduced contact resistance by adopting the optimized Ni diffusion barrier layer | The diffusion barrier layers in thermoelectric generators (TEGs) are widely used to improve their me-chanical/thermal stabilities and energy generation performance; however, thickness dependence of diffusion barrier was rarely reported. In this study, we prepared Bi2Te3-based thermoelectric (TE) modules and Ni diffusion barrier with a thickness of 0-30 mu m to investigate the correlation between the thickness of Ni layers and TE output performance. A TE module with 1 mu m-thick Ni layer harvests a maximum output power of 2.79 mW under a temperature difference (Delta T) of 200 K, which is a higher value than that of a module without a diffusion barrier. Regarding the dependence of TE output performance on the diffusion barrier's thickness, TEGs based on the thicker Ni layers showed lower output performance for all Delta T ranges compared with a 1 mu m-Ni layer TEG. The degradation of TE conversion efficiency was related to the increment of contact resistance (Rc) with the thickness of the diffusion barrier. This Ni thickness-dependent Rc was explored using the transmission line method. The results from this study prove that the thickness of optimized diffusion barriers would maximize the output performance of TEGs, which could be used as a guide for improving the perfor-mance of TEGs.

| ○ | ○ | Article | Enhancement of thermal stability of Nd-Fe-B sintered magnets with tuned Tb-diffused microstructures via temperature control | We investigate the magnetic properties and thermal stability of Tb-diffused Nd-Fe-B magnets prepared at various grain-boundary diffusion temperatures and additional heat-treatment temperatures. These heat-treatment processes improved the coercivity of Tb-diffused Nd-Fe-B magnets than that of the base magnets. The diffusion temperature was found to play a key role in controlling the magnetic thermal stability; temperature variations induced precise changes in the decoupled Tb-diffused microstructures in the magnets. The magnet fabricated at a high diffusion temperature showed the best coercivity at room temperature but poor thermal stability. This was due to the formation of Tb-rich (Tb, Nd)(2)Fe14B phases with high magnetocrystalline anisotropy produced inside the grains and less core-shell structures during diffusion at a higher temperature. The best thermal stability was observed for the magnet prepared at a lower diffusion temperature. This magnet had more well-formed core-shell structures than the remaining magnets. By analyzing its microstructure, using electron microscopy and a micromagnetic equation, it was found that a decoupled microstructure with diffused Tb atoms was mainly responsible for the better thermal magnetic stability. Results obtained herein suggest that an optimized diffusion temperature can provide a magnet with good thermal stability. (C) 2020 Elsevier B.V.

| ○ | ○ | Article | Evaluation and control of residual amorphous phases in carbon-doped MgB2 superconductors | Evaluation and control of amorphous phases in materials are very important for optimizing their properties. Herein, we focus on polycrystalline MgB2 materials prepared with hydrocarbon doping and study the effects of residual amorphous impurities on the superconducting performance. Carbon is known to be an effective element for enhancing the transport critical current under an external magnetic field. The doped samples were prepared under two different nominal conditions, MgB2(C16H10)(x/1)(6) and MgB2-x(C16H10)(x/1)(6), which respectively correspond to additional and substitutional type doping of the MgB2 composition. Regardless of the doping type, both fabrication methods retarded the formation of the MgB2 phase due to the dopant, leading to an increase in amorphous impurities. However, the apparent phenomena that arise from the additional and substitutional types are still elusive. Ultimately, the structural differences due to the impurity effects caused significant changes in the transport critical current performance. The present quantitative analysis of the amorphous impurities thus paves the way to further optimize the doping methodology for MgB2 superconducting materials. (C) 2021 Elsevier B.V.

| ○ | ○ | Article | Imaging Strategy that Achieves Ultrahigh Contrast by Utilizing Differential Esterase Activity in Organs: Application in Early Detection of Pancreatic Cancer | Most nanoparticles show much higher uptake in mononuclear phagocyte system (MPS) organs than in tumors, which has been a long-lasting dilemma in nanomedicine. Here, we report an imaging strategy that selectively decreases MPS organ uptakes by utilizing the differential esterase activity in tumors and other organs. When an esterase-labile radiotracer loaded liposome was injected into the body, radioactivity was rapidly excreted from the liver and spleen after breakage of the ester bond by esterase. However, the lipophilic radiotracer delivered to the tumor remained in the tumor with minimal bond cleavage. The underlying mechanism was fully characterized in vitro and in vivo in colon tumor models. As a proof of concept, the liposomal radiotracer was further optimized for the early detection of pancreatic cancer. The folate-coated liposomal radiotracer showed highly selective tumor uptake. At 4 h postinjection, a pancreatic tumor a few millimeters in size was unambiguously visualized in orthotopic tumor models by PET imaging. At 24 h, an exceptionally high tumor-to-background ratio was achieved, enabling the visualization of tumors alone with minimal background noise. More than 9% of the total radioactivity was found in the tumor. Utilizing our imaging strategy, various tumor imaging agents can be developed for sensitive detection with ultrahigh contrast. | Lee, Woonghee; An, Gwang Il; Park, Hyun; Sarkar, Swarbhanu; Ha, Yeong Su; Huynh, Phuong Tu; Bhise, Abhinav; Bhatt, Nikunj; Ahn, Heesu; Pandya, Darpan N.; Kim, Jung Young; Kim, Seokho; Jun, Eunsung; Kim, Song Cheol; Lee, Kyo Chul; Yoo, Jeongsoo | Kyungpook Natl Univ, Sch Med, Brain Korea KNU Convergence Educ Program Biomed S, Dept Mol Med, Daegu 41944, South Korea; Korea Inst Radiol & Med Sci, Div Appl RI, Seoul 01812, South Korea; Dong A Univ, Dept Hlth Sci, Grad Sch, Busan 49315, South Korea; Univ Ulsan, Coll Med, Asan Med Ctr, Dept Surg,Div Hepatobiliary & Pancreat Surg,AMIST, Seoul 05505, South Korea; Univ Ulsan, Coll Med, Dept Convergence Med, Asan Inst Life Sci, Seoul 05505, South Korea; Asan Med Ctr, Seoul 05505, South Korea | Kim, Kyunghoon/AGO-0079-2022; Sarkar, Swarbhanu/GOG-8975-2022; Bhise, Abhinav/MVY-6473-2025; Kim, Sang-Heon/L-1162-2016; Pandya, Darpan/S-3967-2016 | 55881469700; 36572037400; 56175671100; 36603493100; 36720940600; 56829091800; 57210174595; 55839959200; 56364974400; 36053755200; 7601371677; 59783437700; 55342270400; 55919519700; 42661704100; 8215136400 | yooj@knu.ac.kr; | ACS NANO | ACS NANO | 1936-0851 | 1936-086X | 15 | 11 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2021 | 18.027 | 5.7 | 1.66 | 2025-07-30 | 25 | 27 | imaging agent; imaging strategy; tumor diagnosis; pancreatic cancer; nanoparticle dilemma | NANOPARTICLES; CLEARANCE; PET; NANOTECHNOLOGY; NANOMATERIALS; XENOGRAFTS; LIPOSOMES; LIVER | imaging agent; imaging strategy; nanoparticle dilemma; pancreatic cancer; tumor diagnosis | Cell Line, Tumor; Esterases; Humans; Liposomes; Pancreatic Neoplasms; Positron-Emission Tomography; Tissue Distribution; Diseases; Enzymes; Esters; Medical nanotechnology; Radiation; Radioactive tracers; Radioactivity; esterase; liposome; Background noise; Esterase activities; Mononuclear phagocyte systems; Pancreatic cancers; Pancreatic tumors; Sensitive detection; Tumor imaging agents; Tumor to background ratios; diagnostic imaging; human; pancreas tumor; positron emission tomography; procedures; tissue distribution; tumor cell line; Tumors | English | 2021 | 2021-11-23 | 10.1021/acsnano.1c05165 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Integrated Bioactive Scaffold with Polydeoxyribonucleotide and Stem-Cell-Derived Extracellular Vesicles for Kidney Regeneration | Kidney tissue engineering and regeneration approaches offer great potential for chronic kidney disease treatment, but kidney tissue complexity imposes an additional challenge in applying regenerative medicine for renal tissue regeneration. In this study, a porous pneumatic microextrusion (PME) composite scaffold consisting of poly(lactic-co-glycolic acid) (PLGA, P), magnesium hydroxide (MH, M), and decellularized porcine kidney extracellular matrix (kECM, E) is functionalized with bioactive compounds, polydeoxyribonucleotide (PDRN), and tumour necrosis factor-alpha (TNF-alpha)/interferon-gamma (IFN-gamma)-primed mesenchymal stem-cell-derived extracellular vesicles (TI-EVs) to improve the regeneration and maintenance of a functional kidney tissue. The combination of PDRN and TI-EVs showed a significant synergistic effect in regenerative processes including cellular proliferation, angiogenesis, fibrosis, and inflammation. In addition, the PME/PDRN/TI-EV scaffold induced an effective glomerular regeneration and restoration of kidney function compared to the existing PME scaffold in a partial nephrectomy mouse model. Therefore, such an integrated bioactive scaffold that combines biochemical cues from PDRN and TI-EVs and biophysical cues from a porous PLGA scaffold containing MH and kECM can be used as an advanced tissue engineering platform for kidney tissue regeneration. | Ko, Kyoung-Won; Park, So-Yeon; Lee, Eun Hye; Yoo, Yong-In; Kim, Da-Seul; Kim, Jun Yong; Kwon, Tae Gyun; Han, Dong Keun | CHA Univ, Coll Life Sci, Dept Biomed Sci, Seongnam 13488, Gyeonggi Do, South Korea; Korea Univ, Coll Life Sci & Biotechnol, Div Biotechnol, Seoul 02841, South Korea; Kyungpook Natl Univ, Sch Med, Dept Urol, Daegu 41944, South Korea | Kim, Jun Yong/MBG-4766-2025; Kim, Da-Seul/JGD-5215-2023; Park, Sung/J-2756-2012 | 57114226600; 57222712132; 57189661699; 57158522500; 57195566876; 57214807525; 15073765400; 7403219478 | dkhan@cha.ac.kr; | ACS NANO | ACS NANO | 1936-0851 | 1936-086X | 15 | 4 | SCIE | CHEMISTRY, MULTIDISCIPLINARY;CHEMISTRY, PHYSICAL;MATERIALS SCIENCE, MULTIDISCIPLINARY;NANOSCIENCE & NANOTECHNOLOGY | 2021 | 18.027 | 5.7 | 4.18 | 2025-07-30 | 66 | 68 | kidney regeneration; PLGA scaffold; MH; decellularized kidney ECM; PDRN; primed MSC-derived EVs | TISSUE REGENERATION; TNF-ALPHA; DISEASE; PLGA; ANGIOGENESIS; INFLAMMATION; ACTIVATION; RECEPTORS; FIBROSIS; REVERSE | decellularized kidney ECM; kidney regeneration; MH; PDRN; PLGA scaffold; primed MSC-derived EVs | Animals; Extracellular Vesicles; Kidney; Mice; Polydeoxyribonucleotides; Regeneration; Swine; Tissue Engineering; Tissue Scaffolds; Cell culture; Cell death; Cell proliferation; Magnesium compounds; Stem cells; Tissue; Tissue regeneration; polydeoxyribonucleotide; Cellular proliferations; Chronic kidney disease; Composite scaffolds; Extracellular matrices; Mesenchymal stem cell; Poly lactic-co-glycolic acid; Regenerative process; Tumour necrosis factor alphas; animal; exosome; kidney; mouse; pig; regeneration; tissue engineering; tissue scaffold; Scaffolds (biology) | English | 2021 | 2021-04-27 | 10.1021/acsnano.1c01098 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Mesoporous design of ultrathin NiO nanosheet-coated vertically aligned hexagonal CoS nanoplate core-shell array for flexible all-solid-state supercapacitors | Supercapacitors are becoming the next-generation high-power and carriable energy storage systems. However, large-scale manufacturing of supercapacitors is limited by their inferior energy storage densities, high costs, and rigidity; thus, a cost-effective binder-free approach is required to assemble advanced electrodes on flexible substrates. Multidimensional core-shell electrodes that are vertically aligned on an inexpensive conductive substrate can facilitate improved electrochemical performance. Herein, a core-shell heterostructure of hexagonal cobalt sulfide (CoS) nanoplates encased with ultrathin nickel oxide (NiO) nanosheets was fabricated on a flexible stainless-steel foil by simple chemical methods. Owing to the synergistic effect between the CoS nanoplates and ultrathin NiO nanosheets, the CoS-NiO core-shell electrode showed improved electrochemical performance with a specific capacitance of 1527 F g(-1) at a current density of 1 A g-1, high stability retaining 94% of the capacitance after 5000 charge-discharge cycles, and good capacitive retention during 30-fold enhancement in the current density. Finally, a flexible all-solid-state supercapacitor was fabricated using the CoS-NiO core-shell electrode and dip-coated carbon nanotubes as the positive and negative electrodes, respectively. The fabricated prototype exhibited a maximum energy density of 39 W h kg(-1), energy efficiency of 47%, and cycling stability retaining 89.5% of the capacitance after 5000 charge-discharge cycles.

| ○ | ○ | Article | Point defects control in non-stoichiometric CuInTe2 compounds and its corresponding effects on the microstructure and thermoelectric properties | Thermoelectric properties of CuInTe2 compounds are constrained by characteristic low carrier concentration (similar to 10(17)/cm(3)) and high thermal conductivity (similar to 6 W/mK) at room temperature. These limitations need to be enhanced in order to make these compounds better thermoelectric materials. To resolve the aforementioned issues, we opted to introduce diverse point defects in pristine CuInTe2 through elemental composition control by either removing cation or adding anion, leading to non-stoichiometric compounds. Compounds with the general chemical composition of Cu1-xIn1-yTe2+z (x, y, z = 0, 0.05), representing Cu poor, In poor and Te rich, were studied in this work. The introduced charged point defects alter both the carrier concentration and tunes phonon scattering. It was found that the carrier concentration of the Cu poor sample increased by about 50 times to similar to 10(19)/cm(3) compared to the pristine sample. As a result, the highest power factor of similar to 16.1 mu W/cm K-2 at 723 K was obtained in the Cu poor compound. In addition, a superlattice structure formed by partially ordered Cu vacancies was observed through field-emission transmission electron microscopy, which contributed enhanced phonon scattering. A high ZT value of similar to 0.98 was obtained at 823 K resulting from decreased lattice thermal conductivity and a record high power factor in the Cu poor condition. (C) 2021 Elsevier B.V.

| ○ | ○ | Article | Rapid and convenient crystallization of quantum dot CsPbBr3 inside a phosphate glass matrix | Although inorganic halide perovskite quantum dots (QDs) have promising photophysical properties and a wide range of applications, they suffer from some issues such as poor water and thermal stabilities. Here, we developed a simple strategy to embedded CsPbBr3 QDs in a glass matrix by adopting conventional melt-quenching technique. We systematically presented the modified glass melting and quenching technique for the direct crystallization of CsPbBr3 QDs inside a glass matrix. Crystallization of the QDs took place during the cooling of the quenched hot glass melt. The effect of the concentration of Cs2CO3, PbBr2 and NaBr on the formation of CsPbBr3 QDs size was also identified. The glasses containing CsPbBr3-embedded QDs showed photoluminescence emission stability without any alteration in their emission peaks and full-width at half-maximum for at least six months under ambient conditions. Our results provide new insights into rapid and convenient crystallization of QDs inside the protective glass matrix. The technique can be utilized to fabricate several rare earth ions co-doped QDs glasses for various color tunable lighting optical devices application. (C) 2021 Elsevier B.V.

| ○ | ○ | Article | Unusual relationship between extrusion temperature and tensile strength of extruded Mg-Al-Zn-Ca-Y-MM alloy | This study investigates the effects of extrusion temperature on the microstructural characteristics and mechanical properties of an extruded Mg-9Al-0.8Zn-0.9Ca-0.6Y-0.5MM (AZXWMM91100) alloy and the resulting unusual relationship between the extrusion temperature and the tensile strength of the extruded material. All the extruded materials, i.e., alloy samples extruded at 325 degrees C, 350 degrees C, and 400 degrees C, have a fully recrystallized grain structure and contain abundant undissolved Al8Mn4Y, Al2Ca, and Al2Y particles. A small number of spherical nanosized Mg17Al12 precipitates are formed during extrusion, and their number density decreases with increasing extrusion temperature. The undissolved-particle bands, which are distributed parallel to the extrusion direction, act as obstacles to the growth of recrystallized grains during and after extrusion, which prevents excessive coarsening of grains at high extrusion temperatures. As a result, despite a large increase in the extrusion temperature from 325 degrees C to 400 degrees C, the average grain size of the extruded material increases only slightly, from 17.6 mu m to 23.0 mu m. Concurrently, the tensile strength of the extruded material increases from 183 MPa to 224 MPa; this directly proportional relationship between temperature and strength contrasts with the general inverse relationship between extrusion temperature and tensile strength. An increase in the extrusion temperature leads to an increase in the texture intensity of the extruded material; this increase is attributed to the following phenomena: (i) transition of the dominant dynamic recrystallization (DRX) mechanism from twinning-induced DRX and continuous DRX to discontinuous DRX, (ii) weakening of DRX through particle-stimulated nucleation, and (iii) promotion of the activation of prismatic slip. Therefore, the unusual extrusion temperature-tensile strength relationship for the AZXWMM91100 alloy is a combined result of the grain coarsening suppressed by the undissolved particles and strengthening of the texture hardening effect with the variation in the DRX behavior during extrusion.

| ○ | ○ | Review | Micronutrient status in bariatric surgery patients receiving postoperative supplementation per guidelines: Insights from a systematic review and meta-analysis of longitudinal studies | The micronutrient status and optimal monitoring schedule after bariatric surgery have not been sufficiently assessed. This systematic review and meta-analysis investigated the longitudinal changes in micronutrient status after bariatric surgery. PubMed, EMBASE, and Cochrane Library were searched for articles that measured preoperative and postoperative serum micronutrient levels in patients undergoing Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). Among guideline-adherent studies, the longitudinal changes in micronutrient status were investigated using weighted mean difference (WMD) using a random-effects model. Among the 82 included studies, the guideline adherence rates for micronutrient supplementation after bariatric surgery did not exceed 20%. In patients supplemented per guidelines, vitamin A significantly decreased after RYGB by -7.54 (95% confidence interval [CI], -10.16 to -4.92) mu g/dl at 12-23 months, vitamin E decreased after RYGB by -2.35 (95% CI, -3.65 to -1.05) mu g/dl at >= 24 months, and ferritin by -54.93 (95% CI, -77.19 to -32.67] mu g/L at >= 24 months after SG, compared with baseline, with moderate level of evidence. Significant decreases in micronutrient levels at certain follow-up intervals in studies with supplementation per guidelines need to be considered to establish a post-bariatric micronutrient monitoring schedule for timely detection and management of micronutrient deficiencies. | Ha, Jane; Kwon, Yeongkeun; Kwon, Jin-Won; Kim, Dohyang; Park, Shin-Hoo; Hwang, Jinseub; Lee, Chang Min; Park, Sungsoo | Korea Univ Coll Med, Dept Med, Seoul, South Korea; Korea Univ Anam Hosp, Ctr Obes & Metab Dis, Seoul, South Korea; Korea Univ, Div Foregut Surg, Coll Med, Seoul, South Korea; Kyungpook Natl Univ, BK21 Four Community Based Intelligent Novel Drug, Coll Pharm, Daegu, South Korea; Kyungpook Natl Univ, Res Inst Pharmaceut Sci, Daegu, South Korea; Daegu Univ, Dept Stat, Gyeongbuk, South Korea | ; Park, Sun-Young/B-4634-2014; Lee, Chang/AAA-8912-2021 | 57217000677; 55970203000; 16202951700; 57218821860; 57188744111; 57189231296; 56901528900; 57187346700 | kugspss@korea.ac.kr; | OBESITY REVIEWS | OBES REV | 1467-7881 | 1467-789X | 22 | 7 | SCIE | ENDOCRINOLOGY & METABOLISM | 2021 | 10.867 | 5.8 | 1.16 | 2025-07-30 | 30 | 30 | bariatric surgery; micronutrients; nutritional supplementation; vitamin | Y GASTRIC BYPASS; BONE-MINERAL DENSITY; VITAMIN-D SUPPLEMENTATION; INTESTINAL BACTERIAL OVERGROWTH; LAPAROSCOPIC SLEEVE GASTRECTOMY; OXIDATIVE STRESS MARKERS; MORBIDLY OBESE-PATIENTS; NUTRITIONAL DEFICIENCIES; WEIGHT-LOSS; IRON-DEFICIENCY | bariatric surgery; micronutrients; nutritional supplementation; vitamin | Bariatric Surgery; Dietary Supplements; Gastrectomy; Gastric Bypass; Humans; Longitudinal Studies; Micronutrients; Obesity, Morbid; alpha tocopherol; calcium; calcium regulating agents; cyanocobalamin; ferric carboxymaltose; ferritin; folic acid; iron; magnesium; phosphorus; retinol; thiamine; trace element; vitamin B complex; vitamin D; zinc; trace element; adolescent; adult; aged; bariatric surgery; blood level; diet supplementation; female; follow up; human; male; meta analysis; middle aged; nutritional status; patient compliance; postoperative care; postoperative period; practice guideline; preoperative period; protocol compliance; Review; Roux-en-Y gastric bypass; sleeve gastrectomy; surgical patient; systematic review; bariatric surgery; dietary supplement; gastrectomy; gastric bypass surgery; longitudinal study; morbid obesity | English | 2021 | 2021-07 | 10.1111/obr.13249 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Time and Cost of Ultrasound-Guided Fine-Needle Aspiration Biopsy/Core-Needle Biopsy for Primary Laryngohypopharyngeal Squamous Cell Carcinoma | Objectives This study aimed to evaluate benefits in terms of time and cost of percutaneous ultrasound-guided fine-needle aspiration biopsy/core-needle biopsy (US-FNAB/CNB) for the diagnosis of primary laryngeal and hypopharyngeal squamous cell carcinoma (LHSCC) in comparison with direct laryngoscopic biopsy (DLB) under general anesthesia. Study Design Retrospective case-control study. Setting Single operator of a single center. Subjects and Methods From 2018 to 2019, 28 patients who underwent percutaneous US-FNAB/CNB for the diagnosis of untreated LHSCC were enrolled. All US-FNAB/CNBs were performed in the outpatient department by a single head and neck surgeon. Their results were compared with those of 27 patients who underwent DLB under general anesthesia. Results No major complications occurred in the US-FNAB/CNB and DLB groups. Time to biopsy, time to pathologic diagnosis, and time to treatment initiation in the US-FNAB/CNB and DLB groups were 0 and 14 days (P< .001), 7 and 20 days (P< .001), and 24 and 35 days (P= .001), respectively. Procedure-related costs were $368.5 and $981.0 in the US-FNAB/CNB and DLB groups (P< .001). Conclusions US-FNAB/CNB offers true benefits in terms of time and cost over those given by conventional DLB for diagnosis of LHSCC in indicated patients. | Ahn, Dongbin; Lee, Gil Joon; Sohn, Jin Ho | Kyungpook Natl Univ, Dept Otolaryngol Head & Neck Surg, Sch Med, 130 Dongdeok Ro, Daegu 41944, South Korea | 44761055400; 57193082568; 55165818100 | godlikeu@naver.com; | OTOLARYNGOLOGY-HEAD AND NECK SURGERY | OTOLARYNG HEAD NECK | 0194-5998 | 1097-6817 | 164 | 3 | SCIE | OTORHINOLARYNGOLOGY;SURGERY | 2021 | 5.591 | 5.8 | 0.84 | 2025-07-30 | 4 | 5 | larynx; hypopharynx; biopsy; ultrasound; fine-needle aspiration; core-needle biopsy | WAITING TIME; RADIOTHERAPY; HEAD; LARYNGEAL; CANCER; SAFETY; IMPACT | biopsy; core-needle biopsy; fine-needle aspiration; hypopharynx; larynx; ultrasound | Aged; Aged, 80 and over; Biopsy, Fine-Needle; Carcinoma, Squamous Cell; Case-Control Studies; Cost-Benefit Analysis; Female; Humans; Hypopharyngeal Neoplasms; Image-Guided Biopsy; Laryngeal Neoplasms; Laryngoscopy; Male; Middle Aged; Retrospective Studies; Time Factors; Ultrasonography, Interventional; epinephrine; lidocaine; adult; aged; Article; cancer staging; case control study; clinical article; controlled study; cost effectiveness analysis; direct laryngoscopic biopsy; female; general anesthesia; human; human tissue; hypopharynx; hypopharynx squamous cell carcinoma; laryngeal biopsy; laryngoscopy; male; middle aged; oral paresthesia; pneumonia; retrospective study; time; tooth injury; ultrasound guided fine needle aspiration; comparative study; cost benefit analysis; economics; fine needle aspiration biopsy; hypopharynx tumor; image guided biopsy; interventional ultrasonography; laryngoscopy; larynx tumor; pathology; procedures; squamous cell carcinoma; time factor; very elderly | English | 2021 | 2021-03 | 10.1177/0194599820945953 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
