| ○ | ○ | Article | Pain Intensity at Injection Site during Esophagogastroduodenoscopy Using Long- and Medium-Chain versus Long-Chain Triglyceride Propofol: A Randomized Controlled Double-Blind Study | Background/Aims: The intensities of injection pain resulting from the use of long- and mediumchain triglyceride (LCT/MCT) propofol and conventional LCT propofol during esophagogastroduodenoscopy (EGD) have yet to be compared. We aimed to determine the pain intensity caused by different formulations of propofol and to evaluate the formulation that would be preferred by patients as a sedative agent during their next procedure. Methods: This study was a single-center, randomized, controlled, and double-blind trial. Pain intensity was estimated 30 seconds after propofol injection by an examiner who was blinded to the group assignment using a numeric (0-10) pain rating scale (NPRS). After 1 week, the patients were asked whether they could recall the pain and were willing to receive the same agent for their next EGD. Results: One hundred twenty-nine patients were randomly assigned to LCT/MCT or LCT group. Although there was no significant difference in pain incidence between the LCT/MCT and LCT groups (52.9% vs 65.6%, p=0.156), the pain intensity was significantly lower in the LCT/MCT group (NPRS median [interquartile range]; 1 (0-2) vs 2 (0-5), p=0.005). After 1 week, fewer patients in the LCT/MCT group recalled the pain (19.1% vs 63.9%, p<0.001) and more patients in the LCT/MCT group were more willing to use the same agent for their next procedure (86.8% vs 72.1%, p=0.048) than in the LCT group. Conclusions: LCT/MCT propofol significantly reduced injection pain intensity compared to LCT propofol during EGD and preferred by patients as a sedative agent during their next EGD. | Lee, Joon Seop; Kim, Eun Soo; Cho, Kwang Bum; Park, Kyung Sik; Lee, Yoo Jin; Lee, Ju Yup | Kyungpook Natl Univ, Kyungpook Natl Univ Hosp, Sch Med, Dept Internal Med, Daegu, South Korea; Keimyung Univ, Dept Internal Med, Sch Med, Daegu, South Korea | Kim, Sang/J-5398-2012; Lee, Yoojin/AAB-9799-2022 | 57205374013; 57203086704; 7403956834; 56903328900; 55531365900; 55891683700 | dandy813@hanmail.net; | GUT AND LIVER | GUT LIVER | 1976-2283 | 2005-1212 | 15 | 4 | SCIE | GASTROENTEROLOGY & HEPATOLOGY | 2021 | 4.321 | 46.8 | 0.69 | 2025-07-30 | 12 | 11 | Endoscopy; Medium chain triglyceride; Propofol; Pain | TRADITIONAL SEDATIVE AGENTS; GASTROINTESTINAL ENDOSCOPY; MECHANISM; QUALITY | Endoscopy; Medium chain triglyceride; Pain; Propofol | Anesthetics, Intravenous; Double-Blind Method; Endoscopy, Digestive System; Humans; Pain; Propofol; Triglycerides; long chain triacylglycerol; medium chain triacylglycerol; propofol; intravenous anesthetic agent; propofol; triacylglycerol; adult; Article; controlled study; double blind procedure; drug dosage form comparison; female; gastrointestinal endoscopy; human; incidence; injection site pain; major clinical study; male; numeric rating scale; pain intensity; randomized controlled trial; sedation; digestive tract endoscopy; pain | English | 2021 | 2021-07 | 10.5009/gnl20243 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |
| ○ | ○ | Article | Piperonyl butoxide, a synergist of pesticides can elicit male-mediated reproductive toxicity | A semi-synthetic methylenedioxyphenyl compound piperonyl butoxide (PBO) has been used as a ubiquitous synergist to increase the insecticidal effect of pesticides for agricultural and household use. Despite previously demonstrated effects of PBO, the detailed mechanism of PBO in spermatozoa and reproductive toxic effects on male germ cells have not been fully elucidated. Therefore, this study evaluated the effects of PBO on various sperm functions during capacitation and clarified the mechanisms of reproductive toxic effects on male fertility at different concentrations of PBO (0.1, 1, 10, and 100 ?M). Sperm motility and kinematics were assessed using computer-assisted sperm analysis and the status of capacitation was evaluated using combined H33258/chlortetracycline (CTC) staining. Intracellular adenosine triphosphate (ATP) and cell viability levels were also measured. In addition, protein kinase A (PKA) activity and protein tyrosine phosphorylation were evaluated. In addition, in vitro fertilization was performed to determine the effects of PBO on cleavage and blastocyst formation rates. We found that PBO significantly decreased sperm motility, kinematics, and acrosome-reacted and capacitated spermatozoa. In addition, PBO suppressed the intracellular ATP levels and directly affected cell viability. Moreover, PBO detrimentally decreased the activation of PKA and altered the levels of tyrosinephosphorylated proteins. Consequently, cleavage and blastocyst formation rates were significantly reduced in a dose-dependent manner. In line with our observations, the synergist of pesticides PBO may directly and/or indirectly cause disorder in male fertility. Hence, we suggest that careful attention is made to consider reproductive toxicity when using PBO as a synergist. | Bae, Jeong-Won; Kwon, Woo-Sung | Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju 37224, Gyeongsangbuk D, South Korea; Kyungpook Natl Univ, Dept Anim Biotechnol, Sangju 37224, Gyeongsangbuk D, South Korea | Kwon, Woo-Sung/J-6731-2019; Bae, Jeong-Won/AAH-4932-2021; Kwon, Woo-Sung/J-4391-2014 | 57211231093; 54383715800 | wskwon@knu.ac.kr; | REPRODUCTIVE TOXICOLOGY | REPROD TOXICOL | 0890-6238 | 1873-1708 | 100 | SCIE | REPRODUCTIVE BIOLOGY;TOXICOLOGY | 2021 | 3.421 | 46.8 | 1.13 | 2025-07-30 | 10 | 14 | Piperonyl butoxide; Synergist; Spermatozoa; Protein kinase A; Protein tyrosine phosphorylation | Piperonyl butoxide; Protein kinase A; Protein tyrosine phosphorylation; Spermatozoa; Synergist | Acrosome Reaction; Animals; Cell Survival; Embryonic Development; Female; Fertilization; Infertility, Male; Male; Mice; Mice, Inbred ICR; Pesticide Synergists; Piperonyl Butoxide; Reproduction; Sperm Capacitation; Sperm Motility; Spermatozoa; adenosine triphosphate; cyclic AMP dependent protein kinase; piperonyl butoxide; pesticide; piperonyl butoxide; acrosome reaction; animal cell; animal experiment; animal model; Article; blastocyst; cell viability; controlled study; enzyme activation; enzyme activity; female; in vitro fertilization; male; male fertility; mouse; nonhuman; oocyte cleavage; protein phosphorylation; reproductive toxicity; semen analysis; sperm capacitation; spermatozoon motility; animal; cell survival; drug effect; embryo development; fertilization; Institute for Cancer Research mouse; male infertility; physiology; reproduction; spermatozoon | English | 2021 | 2021-03 | 10.1016/j.reprotox.2021.01.010 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | The deleterious toxic effects of bifenthrin on male fertility | Bifenthrin (BF), a broad-spectrum synthetic pyrethroid insecticide, has been generally used to eradicate harmful insects. However, according to the U.S. EPA, BF has been classified as a ?Class C? carcinogenic ingredient. Furthermore, a previous study reported that BF was considered as endocrine-disrupting chemicals and causes reproductive toxicity in mammals. Despite the various effects of BF, there is a scarcity of studies about its adverse effects on male fertility. Therefore, this study was conducted to determine the effects of BF on sperm functions at various concentrations (0.1, 1, 10, and 100 ?M), including a control. Sperm motility and kinematics, capacitation status, intracellular ATP levels, cell viability, PKA activation, and protein tyrosine phosphorylation were measured. Moreover, fertilization and early embryonic development were examined through in vitro fertilization. Results showed that sperm motility and kinematic parameters were significantly decreased at a high BF concentration. Consequently, the sperm capacitation status exhibited significant alteration according to the treatment concentration. Intracellular ATP levels were significantly decreased at 10 and 100 ?M treatment concentrations. Moreover, the levels of phospho-PKA substrates were significantly increased in a dose-dependent manner. In contrast, the levels of phospho-tyrosine substrates were significantly decreased at 10 and 100 ?M treatment concentrations. BF treatment also diminished the rate of blastocyst formation. Altogether, our results demonstrated that BF causes detrimental effects on sperm function and can influence fertilization. Therefore, our study results might be helpful in understanding the adverse effects of BF on male fertility. | Bae, Jeong-Won; Kwon, Woo-Sung | Kyungpook Natl Univ, Dept Anim Sci & Biotechnol, Sangju 37224, Gyeongsangbuk D, South Korea; Kyungpook Natl Univ, Dept Anim Biotechnol, Sangju 37224, Gyeongsangbuk D, South Korea | ; Kwon, Woo-Sung/J-6731-2019; Kwon, Woo-Sung/J-4391-2014; Bae, Jeong-Won/AAH-4932-2021 | 57211231093; 54383715800 | wskwon@knu.ac.kr; | REPRODUCTIVE TOXICOLOGY | REPROD TOXICOL | 0890-6238 | 1873-1708 | 101 | SCIE | REPRODUCTIVE BIOLOGY;TOXICOLOGY | 2021 | 3.421 | 46.8 | 1.13 | 2025-07-30 | 16 | 17 | Bifenthrin; Spermatozoa; Reproductive toxicity; Male infertility | PRESSURIZED LIQUID EXTRACTION; PYRETHROID INSECTICIDE; PESTICIDES; EXPOSURE; SPERM; SPERMATOZOA; PERMETHRIN; CYPERMETHRIN; METABOLISM; COMMUNITY | Bifenthrin; Male infertility; Reproductive toxicity; Spermatozoa | Adenosine Triphosphate; Animals; Blastocyst; Cell Survival; Cyclic AMP-Dependent Protein Kinases; Embryonic Development; Female; Fertility; Insecticides; Male; Mice, Inbred ICR; Phosphorylation; Pyrethrins; Sperm Capacitation; Sperm Motility; Spermatozoa; Tyrosine; bifenthrin; cyclic AMP dependent protein kinase; adenosine triphosphate; bifenthrin; cyclic AMP dependent protein kinase; insecticide; pyrethroid; tyrosine; animal cell; animal experiment; animal model; animal tissue; Article; blastocyst; cell level; cell viability; chemical analysis; concentration (parameter); controlled study; embryo; embryo development; enzyme activation; female; in vitro fertilization; male; male fertility; male infertility; nonhuman; protein phosphorylation; sperm capacitation; sperm function; spermatozoon motility; toxicity testing; animal; cell survival; drug effect; fertility; Institute for Cancer Research mouse; metabolism; phosphorylation; physiology; spermatozoon | English | 2021 | 2021-04 | 10.1016/j.reprotox.2021.03.002 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||

| ○ | ○ | Article | Enhancement of catabolite regulatory genes in Saccharomyces cerevisiae to increase ethanol production using hydrolysate from red seaweed Gloiopeltis furcata | Glucose and galactose are monosaccharides obtained from Gloiopeltis furcata (Red algae). A total monosaccharide yield of 62.3 g/L was obtained from G. furcata using thermal acid hydrolysis and enzymatic saccharification. Activated carbon was used to eliminate hydroxymethylfurfural (HMF) from the hydrolysate. Previously obtained monosaccharides are used for ethanol production by Saccharomyces cerevisiae. S. cerevisiae consumes glucose first, then galactose. The methods for reducing fermentation time and increasing the ethanol yield coefficient using the simultaneous consumption of glucose and galactose have been evaluated. Gal3p and Gal80p of S. cerevisiae act as signal transducers that govern the galactose inducer Gal4p mediated transcriptional activation of the Gal gene family. Gal80p binds to Gal4p for transcription deactivation. Therefore, Gal80p was deleted for Gal4p expression without interruption. | Park, Yu Rim; Yang, Ji Won; Sunwoo, In Yung; Jang, Byeong-Kwan; Kim, Soo Rin; Jeong, Gwi-Taek; Kim, Sung-Koo | Pukyong Natl Univ, Dept Biotechnol, Busan 48513, South Korea; Umea Univ, Dept Chem, SE-90187 Umea, Sweden; Kyungpook Natl Univ, Sch Food Sci & Biotechnol, Daegu 41566, South Korea | Kim, Soo Rin/X-2192-2019; Jang, Byeong Kwan/IQV-9121-2023 | 57216661150; 57217500123; 56506970700; 57220054462; 36659584200; 7102664797; 57195386876 | skkim@pknu.ac.kr; | JOURNAL OF BIOTECHNOLOGY | J BIOTECHNOL | 0168-1656 | 1873-4863 | 333 | SCIE | BIOTECHNOLOGY & APPLIED MICROBIOLOGY | 2021 | 3.595 | 46.9 | 0.54 | 2025-07-30 | 7 | 7 | Saccharomyces cerevisiae; Bioethanol; Gloiopeltis furcata; CRISPR Cas-9 | GALACTOSE METABOLISM; REAL-TIME; YEAST; SACCHARIFICATION; PRETREATMENT; ACTIVATION; PROTEIN; MODEL; GAL1 | Bioethanol; CRISPR Cas-9; Gloiopeltis furcata; Saccharomyces cerevisiae | Ethanol; Galactose; Genes, Regulator; Repressor Proteins; Rhodophyta; Saccharomyces cerevisiae; Saccharomyces cerevisiae Proteins; Seaweed; Transcription Factors; Activated carbon; Algae; Bioethanol; Enzymatic hydrolysis; Ethanol; Saccharification; Transcription; Yeast; alcohol; fungal enzyme; Gal3p protein; Gal4p protein; Gal80p protein; galactose; glucose; unclassified drug; alcohol; repressor protein; Saccharomyces cerevisiae protein; transcription factor; Bio-ethanols; Cerevisiae; CRISPR cas-9; Ethanol production; Gloiopeltis furcatum; Red algae; Red seaweeds; Regulatory genes; S.cerevisiae; Saccharomyces; alcohol production; Article; catabolism; controlled study; fermentation; fungal strain; gene deletion; gene overexpression; Gloiopeltis furcata; multigene family; nonhuman; priority journal; protein protein interaction; red alga; regulator gene; Saccharomyces cerevisiae; seaweed; signal transduction; time; transcription initiation; wild type; genetics; red alga; regulator gene; Saccharomyces cerevisiae; Glucose | English | 2021 | 2021-06-10 | 10.1016/j.jbiotec.2021.04.004 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | ○ | Article | What Makes Oncologists Feel Compassion Fatigue? Qualitative Findings From Korea | This study explored oncologists' compassion fatigue in their practice with cancer patients and families. Qualitative in-depth interviews were conducted. A purposeful sample of nine oncologists was recruited from three hospitals in Korea. We used a hybrid of the theory-driven deductive approach and data-driven inductive approach based on the transactional model of physician compassion. Oncologists shared contexts from which their compassion fatigue stems based on four categories: physician factors, clinical factors, patient and family factors, and environmental and institutional factors. Given the nature of their job, oncologists should receive interventions that improve resilience and reduce compassion fatigue. We suggest interventions that promote appropriate levels of compassion and reduce interfering barriers. | Yi, Jaehee; Kim, Min Ah; Choi, Kwonho | Univ Utah, Salt Lake City, UT USA; Sungkyunkwan Univ, Seoul, South Korea; Kyungpook Natl Univ, Daegu, South Korea | ; Yi, Jaehee/A-2731-2010 | 24402245900; 55966004600; 57200582649 | minahkim@skku.edu; | SAGE OPEN | SAGE OPEN | 2158-2440 | 11 | 1 | SSCI | SOCIAL SCIENCES, INTERDISCIPLINARY | 2021 | 2.032 | 46.9 | 0.23 | 2025-07-30 | 1 | 1 | cancer care; Korea; compassion fatigue; oncology; qualitative research | PEDIATRIC ONCOLOGY; PATIENT LOSS; JOB STRESS; CARE; BURNOUT; GRIEF; WORK; PHYSICIANS; PROGRAM; IMPACT | cancer care; compassion fatigue; Korea; oncology; qualitative research | English | 2021 | 2021-01 | 10.1177/21582440211006712 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||
| ○ | ○ | Article | Aquaporins implicated in the cell proliferation and the signaling pathways of cell stemness | Aquaporins (AQPs) are water channel proteins facilitating passive transport of water and other small molecules across biomembranes. Regulation of osmotic homeostasis via AQPs is accompanied by dynamic participation of various cellular signaling pathways. Recently emerging evidence reveals that functional roles of AQPs are further extended from the osmotic regulation via water permeation into the cell proliferation and differentiation. In particular, anomalous expression of AQPs has been demonstrated in various types of cancer cells and cancer stem-like cells and it has been proposed as markers for proliferation and progression of cancer cells. Thus, a more comprehensive view on AQPs could bring a great interest in the cell stemness accompanied by the expression of AQPs. AQPs are broadly expressed across tissues and cells in a cell type-and lineage-specific manner during development via spatiotemporal transcriptional regulation. Moreover, AQPs are expressed in various adult stem cells and cells associated with a stem cell niche as well as cancer stem-like cells. However, the expression and regulatory mechanisms of AQP expression in stem cells have not been well understood. This review highlighted the AQPs expression in stem cell niches/stem cells and the involvement of AQPs in the cell proliferation and signaling pathways associated with cell stemness.

| ○ | ○ | Article | Extremities for Statistical Submanifolds in Kenmotsu Statistical Manifolds | Kenmotsu geometry is a valuable part of contact geometry with nice applications in other fields such as theoretical physics. In this article, we study the statistical counterpart of a Kenmotsu manifold, that is, Kenmotsu statistical manifold with some related examples. We investigate some statistical curvature properties of Kenmotsu statistical manifolds. It has been shown that a Kenmotsu statistical manifold is not a Ricci-flat statistical manifold by constructing a counter-example. Finally, we prove a very well-known Chen-Ricci inequality for statistical submanifolds in Kenmotsu statistical manifolds of constant phi-sectional curvature by adopting optimization techniques on submanifolds. This article ends with some concluding remarks. | Siddiqui, Aliya Naaz; Suh, Young Jin; Bahadir, Oguzhan | Maharishi Markandeshwar Deemed Univ, Dept Math, Ambala 133207, Haryana, India; Kyungpook Natl Univ, Coll Nat Sci, Dept Math, Daegu 41566, South Korea; Kyungpook Natl Univ, Coll Nat Sci, RIRCM, Daegu 41566, South Korea; Kahramanmaras Sutcu Imam Univ, Fac Sci & Letters, Dept Math, Kahrmanmaras, Turkey | Siddiqui, Aliya/AFV-7739-2022; Bahadır, Oğuzhan/GXG-3859-2022 | 57196702209; 7202260479; 57211030290 | aliyanaazsiddiqui9@gmail.com;yjsuh@knu.ac.kr;oguzbaha@gmail.com; | FILOMAT | FILOMAT | 0354-5180 | 35 | 2 | SCIE | MATHEMATICS, APPLIED;MATHEMATICS | 2021 | 0.988 | 47.0 | 1.12 | 2025-07-30 | 3 | 5 | Ricci curvature; Chen-Ricci inequality; Kenmotsu statistical manifolds; Statistical immersions | CURVATURE | Chen-Ricci inequality; Kenmotsu statistical manifolds; Ricci curvature; Statistical immersions | English | 2021 | 2021 | 10.2298/fil2102591s | 바로가기 | 바로가기 | 바로가기 | 바로가기 | |||

| ○ | ○ | Article | Comparison of Dermoscopic Features Between Melanoacanthomas and Melanoacanthoma-Like Malignant Melanomas in Korean Patients | Background A melanoacanthoma (MA) is a pigmented variant of seborrheic keratosis. Owing to the pigmentation, MAs may mimic the clinical appearance of malignant melanomas (MMs). However, the dermoscopic patterns of MAs and MA-like MMs have rarely been compared. Objective To elucidate the clinical and dermoscopic differences between MAs and MA-like MMs. Methods This study included 77 MA and 33 MA-like MM patients. We retrospectively reviewed the medical records, clinical findings, and dermoscopic findings of the two groups. Results Crypts and comedo-like openings (71.4%) in MAs and the blue-white veil (60.6%) in MMs were the most common dermoscopic findings. Crypts, comedo-like opening, milia-like cysts, fissures, and hairpin vessels appeared more frequently in MAs (P < .05). However, atypical pigment networks, blue-white veils, pseudopods and streaks, and atypical vessels were more common in MMs (P < .05). MAs often showed melanoma-specific dermoscopic findings, especially blue-white veils (22.1%). Furthermore, fissures (42.4%), crypts (21.2%), and comedo-like openings (15.2%) were observed in MMs, although they are typically benign patterns. Conclusion Differences in dermoscopic patterns might provide important clues for the differential diagnosis of MA-like lesions. However, MAs such as MMs and true-benign MAs may overlap clinically in appearance and on dermoscopy. Several benign patterns were frequently observed in MMs (fissures, globular pattern, crypts, comedo-like openings, cerebriform appearance, and milia-like cysts), and several malignant patterns were observed in MAs (blue-white veil, pseudopod, and atypical pigment network). Importantly, if any of the melanoma-associated features or atypical vessels are present, the lesion should be biopsied to establish a diagnosis. | Roh, Dongyoung; Ha, Dae-Lyong; Kim, Yeona; Shin, Kihyuk; Kim, Hoon-Soo; Ko, Hyun-Chang; Kim, Byung-Soo; Kim, Moon-Bum | Pusan Natl Univ, Sch Med, Dept Dermatol, 179 Gudeok Ro, Busan, South Korea; Pusan Natl Univ, Yangsan Hosp, Dept Dermatol, Yangsan, South Korea; Pusan Natl Univ Hosp, Biomed Res Inst, Busan, South Korea; Kyungpook Natl Univ, Sch Med, Dept Dermatol, Daegu, South Korea | Kim, Ko Eun/AER-3267-2022; Ko, Hyun-chang/ABF-7418-2021; Kwon, Ohsang/J-2733-2012 | 57201981979; 57201367090; 57221436030; 57218366956; 57206211956; 57202265435; 55726523900; 7406088339 | drkmp@hanmail.net; | JOURNAL OF CUTANEOUS MEDICINE AND SURGERY | J CUTAN MED SURG | 1203-4754 | 1615-7109 | 25 | 3 | SCIE | DERMATOLOGY | 2021 | 2.854 | 47.1 | 0.31 | 2025-07-30 | 2 | 3 | dermoscopy; melanoacanthoma; melanoma | dermoscopy; melanoacanthoma; melanoma | acanthoma; adult; Article; clinical feature; comparative study; controlled study; differential diagnosis; epiluminescence microscopy; female; human; Korean (people); major clinical study; male; melanoacanthoma; melanoacanthoma like malignant melanoma; melanoma; phenotype; retrospective study; South Korea; tumor localization | English | 2021 | 2021-05 | 10.1177/1203475420977470 | 바로가기 | 바로가기 | 바로가기 | 바로가기 | ||
| ○ | Article | Clinical factors that influence the occurrence of symptomatic pseudoaneurysms and arteriovenous fistulas after partial nephrectomy: multi-institutional study of renal function outcomes after one year of selective arterial embolization | Purpose: Renal artery pseudoaneurysms (RAPs) and arteriovenous fistulas (AVFs) are rare but potentially life-threatening complications after partial nephrectomy (PN). Selective arterial embolization (SAE) is an effective method for controlling RAPs/AVFs. We assessed the clinical factors affecting the occurrence of RAPs/AVFs after PN and the effects of SAE on postsurgical renal function. Materials and Methods: Four hundred ninety-three patients who underwent PN were retrospectively reviewed. They were placed in either the SAE or the non-SAE group. The effects of clinical factors, including R.E.N.A.L. scores, on the occurrence of RAPs/AVFs were analyzed. The influence of SAE on the estimated glomerular filtration rate (eGFR) during the first postoperative year was evaluated. Results: Thirty-three (6.7%) patients experienced RAPs/AVFs within 8 days of the median interval between PN and SAE. The SAE group had significantly higher R.E.N.A.L. scores, higher N component scores, and higher L component scores (all, p <0.05). In the multivariate analysis, higher N component scores were associated with the occurrence of RAPs/AVFs (Odds ratio: 1.96, p=0.039). In the SAE group, the mean 3-day postembolization eGFR was significantly lower than the mean 3-day postoperative eGFR (p <0.01). This difference in the eGFRs was still present 1 year later. Conclusions: Renal tumors located near the renal sinus and collecting system were associated with a higher risk for RAPs/AVFs after PN. Although SAE was an effective method for controlling symptomatic RAPs/AVFs after PN, a procedure-related impairment of renal function after SAE could occur and still be present at the end of the first postoperative year. | Lee, Chan Ho; Ha, Hong Koo; Ku, Ja Yoon; Seo, Won Ik; Choi, Seock Hwan | Inje Univ, Coll Med, Busan Paik Hosp, Dept Urol, Busan, South Korea; Pusan Natl Univ, Pusan Natl Univ Hosp, Sch Med, Dept Urol, Busan, South Korea; Kyungpook Natl Univ, Sch Med, Dept Urol, Daegu, South Korea | ; Ha, Hong/W-1873-2019 | skhwan.script@gmail.com; | INTERNATIONAL BRAZ J UROL | INT BRAZ J UROL | 1677-5538 | 1677-6119 | 47 | 1 | SCIE | UROLOGY & NEPHROLOGY | 2021 | 3.05 | 47.2 | 5 | Aneurysm, False; Nephrectomy; Arteriovenous Fistula | INVASIVE PARTIAL NEPHRECTOMY; IATROGENIC VASCULAR-LESIONS; EARLY POSTOPERATIVE PERIOD; RADICAL NEPHRECTOMY | English | 2021 | 2021 (JAN-FEB) | 10.1590/s1677-5538.ibju.2019.0789 | 바로가기 | 바로가기 | 바로가기 | |||||||||
| ○ | ○ | Article | Green biomimetic silver nanoparticles utilizing the red algaeAmphiroa rigidaand its potent antibacterial, cytotoxicity and larvicidal efficiency | The present investigation reports a simple, rapid, inexpensive, and eco-friendly approach for synthesizingAmphiroa rigida-mediated silver nanoparticles (AR-AgNPs) for the first time. The biomimetic synthesized AR-AgNPs were characterized by both spectral and microscopic analysis. The UV-visible spectrum showed the surface plasmon peak at 420 nm, which indicated the formation of AR-AgNPs. X-ray diffraction characterization of AR-AgNPs showed a face-centered cubic crystal (25 nm) and the transmission electron microscope micrograph showed spherical shape. The functional group of polysaccharide that plays a major role as a stabilizing and reducing agent is confirmed by Fourier-transform infrared spectroscopy. The biomimetic synthesized AR-AgNPs showed antibacterial activity againstStaphylococcus aureus(21 +/- 0.2 mm) andPseudomonas aeruginosa(15 +/- 0.2 mm).Further, the cytotoxic effects of AR-AgNPs against MCF-7 human breast cancer cells were observed through acridine orange-ethidium bromide and Hoechst staining. Besides, AR-AgNPs are found to be inhibit the growth of 3rd and 4th instar larvae ofAedes aegyptiin a dose-dependent manner. | Gopu, Mani; Kumar, Ponnuchamy; Selvankumar, Thangasamy; Senthilkumar, Balakrishnan; Sudhakar, Chinnappan; Govarthanan, Muthusamy; Kumar, Rathakrishnan Selva; Selvam, Kandasamy | Mahendra Arts & Sci Coll Autonomous, PG & Res Dept Biotechnol, Namakkal 637501, Tamil Nadu, India; Alagappa Univ, Dept Anim Hlth & Management, Food Chem & Mol Canc Biol Lab, Karaikkudi 630003, Tamil Nadu, India; Haramaya Univ, Coll Hlth & Med Sci, Dept Med Microbiol, POB 235, Harar, Ethiopia; Kyungpook Natl Univ, Dept Environm Engn, Daegu 41566, South Korea; Mahendra Arts & Sci Coll Autonomous, PG & Res Dept Chem, Namakkal 637501, Tamil Nadu, India | Sudhakar, Chinnappan/Y-8277-2019; Selvam, Kandasamy/AAN-5860-2020; Thangaswamy, Selvankumar/M-5777-2015; Balakrishnan, Senthilkumar/A-8552-2016; Selvankumar, Thangaswamy/W-1639-2019; Govarthanan, Muthusamy/C-1491-2014; Balakrishnan, Senthilkumar/J-6908-2014; Muthusamy, Govarthanan/C-1491-2014; R, SELVA KUMAR/E-8226-2015; Ponnuchamy, Kumar/D-3470-2013 | 57218534890; 55173720800; 24485017700; 56640778400; 56480308500; 54881927600; 57218534200; 57197362853 | ksk.selvam@gmail.com; | BIOPROCESS AND BIOSYSTEMS ENGINEERING | BIOPROC BIOSYST ENG | 1615-7591 | 1615-7605 | 44 | 2 | SCIE | BIOTECHNOLOGY & APPLIED MICROBIOLOGY;ENGINEERING, CHEMICAL | 2021 | 3.434 | 47.2 | 4.44 | 2025-07-30 | 61 | 72 | Red algae; Amphiroa rigida; Silver nanoparticles; Antibacterial activity; Cytotoxicity | ANTICANCER ACTIVITY; EXTRACT; DYE | Amphiroa rigida; Antibacterial activity; Cytotoxicity; Red algae; Silver nanoparticles | Aedes; Animals; Anti-Bacterial Agents; Biomimetic Materials; Cytotoxins; Green Chemistry Technology; Humans; Insecticides; Larva; MCF-7 Cells; Metal Nanoparticles; Pseudomonas aeruginosa; Rhodophyta; Silver; Staphylococcus aureus; Algae; Bacteria; Biomimetics; Fourier transform infrared spectroscopy; Metal nanoparticles; Silver nanoparticles; Surface plasmons; Transmission electron microscopy; acridine orange; polysaccharide; silver nanoparticle; streptomycin; antiinfective agent; biomimetic material; cytotoxin; insecticide; metal nanoparticle; silver; Anti-bacterial activity; Cytotoxic effects; Dose-dependent manner; Face centered cubic crystals; Mcf-7 human breast cancer cells; Microscopic analysis; Pseudomonas aeruginosa; Surface plasmon peak; Aedes aegypti; Amphiroa rigida; antibacterial activity; antilarval activity; apoptosis; broth dilution; cell structure; controlled study; cytotoxicity; drug synthesis; female; Fourier transform infrared spectroscopy; green chemistry; growth inhibitory concentration; human; human cell; in vitro study; larva; larvicidal activity; MCF-7 cell line; minimum inhibitory concentration; nonhuman; particle size; priority journal; Pseudomonas aeruginosa; red alga; Staphylococcus aureus; surface property; transmission electron microscopy; ultraviolet visible spectroscopy; X ray diffraction; zone of inhibition; Aedes; animal; chemistry; growth, development and aging; red alga; synthesis; Synthesis (chemical) | English | 2021 | 2021-02 | 10.1007/s00449-020-02426-1 | 바로가기 | 바로가기 | 바로가기 | 바로가기 |
