| 1 | Mitophagy links oxidative stress conditions and neurodegenerative diseases显示文摘Mitophagy is activated by a number of stimuli, including hypoxia, energy stress, and increased oxidative phosphorylation activity. Mitophagy is associated with oxidative stress conditions and central neurodegenerative diseases. Proper regulation of mitophagy is crucial for maintaining homeostasis; conversely, inadequate removal of mitochondria through mitophagy leads to the generation of oxidative species, including reactive oxygen species and reactive nitrogen species, resulting in various neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, Huntington's disease, and amyotrophic lateral sclerosis. These diseases are most prevalent in older adults whose bodies fail to maintain proper mitophagic functions to combat oxidative species. As mitophagy is essential for normal body function, by targeting mitophagic pathways we can improve these disease conditions. The search for effective remedies to treat these disease conditions is an ongoing process, which is why more studies are needed. Additionally, more relevant studies could help establish therapeutic conditions, which are currently in high demand. In this review, we discuss how mitophagy plays a significant role in homeostasis and how its dysregulation causes neurodegeneration. We also discuss how combating oxidative species and targeting mitophagy can help treat these neurodegenerative diseases. | Ulfuara Shefa Na Young Jeong In Ok Song Hyung-Joo Chung Dokyoung Kim Junyang Jung Youngbuhm Huh | 2019 | Neural Regeneration Research2019,14,5: | 21 |
| 2 | Modern stalagmite oxygen isotopic composition and its implications of climatic change from a high-elevation cave in the eastern Qinghai-Tibet Plateau over the past 50 years显示文摘An oxygen isotope record of a stalagmite from Huanglong Cave in the eastern Qinghai-Tibet Plateau dated with 230Th and 210Pb methods provides variations of the Asian monsoon with an average resolu-tion of 1 year over the past 50 years. This study shows that the δ18O of dripwater in the cave represents the annual mean δ18O of local meteoric precipitation and the stalagmites were deposited in isotopic equilibrium. A comparison of the stalagmite δ18O record with instrumentally meteorological data indi-cates that shifts of the δ18O are largely controlled by the amount effect of meteoric precipitation con-veyed through the southwest monsoon(the Indian monsoon) and less affected by temperature. Therefore,the variations of δ18O record reflect the changes in monsoon precipitation on inter-annual time scales under the influence of the southwest monsoon. Like many other stalagmite δ18O records in the Asian monsoon regions,the δ18O record of the stalagmite from Huanglong Cave also reveals a gradually enriched trend during the past 50 years,i.e. relatively enriched in 18O. This trend may indicate the decline of the Asian monsoon intensity which is consistent with the decrease of monsoon indices. The weakening of the modern Asian monsoon well matched with the temperature changes in strato-sphere,which may illustrate that the weakening of the monsoon mainly results from the lowering of solar radiation. | YANG XunLin ZHANG PingZhong CHEN FaHu HUH Chih-an LI HongChun CHENG Hai Kathleen R.

| 3 | Mitochondria-targeting drug conjugates for cytotoxic, anti-oxidizing and sensing purposes:current strategies and future perspectives显示文摘mitochondrial-targeting moieties to anticancer drugs, antioxidants and sensor molecules. Among them, the most widely applied mitochondrial targeting moiety is triphenylphosphonium(TPP), which is a delocalized cationic lipid that readily accumulates and penetrates through the mitochondrial membrane due to the highly negative mitochondrial membrane potential. Other moieties, including short peptides,dequalinium, guanidine, rhodamine, and F16, are also known to be promising mitochondrial targeting agents. Direct conjugation of mitochondrial targeting moieties to anticancer drugs, antioxidants and sensors results in increased cytotoxicity, anti-oxidizing activity and sensing activity, respectively,compared with their non-targeting counterparts, especially in drug-resistant cells. Although many mitochondria-targeted anticancer drug conjugates have been investigated in vitro and in vivo, further clinical studies are still needed. On the other hand, several mitochondria-targeting antioxidants have been analyzed in clinical phases I, II and III trials, and one conjugate has been approved for treating eye disease in Russia. There are numerous ongoing studies of mitochondria-targeted sensors. | Gantumur Battogtokh Yeon Su Choi Dong Seop Kang Sang Jun Park Min Suk Shim Kang Moo Huh Yong-Yeon Cho Joo Young Lee Hye Suk Lee Han Chang Kang | 2018 | Acta Pharmaceutica Sinica B2018,8,6: | 17 |
| 4 | Anticoagulation and delayed bowel resection in the management of mesenteric venous thrombosis显示文摘Acute mesenteric venous thrombosis is potentially lethal because it can result in mesenteric ischemia and,ultimately,bowel infarction requiring surgical intervention.Systemic anticoagulation for the prevention of thrombus propagation is a well-recognized treatment modality and the current mainstay therapy for patients with acute mesenteric venous thrombosis.However,the decision between prompt surgical exploration vs conservative treatment with anticoagulation is somewhat difficult in patients with suspected bowel ischemia.Here we describe a patient with acute mesenteric venous thrombosis who presented with bowel ischemia and was treated with anticoagulation and delayed short-segment bowel resection. | Hyung-Kee Kim Jae Min Chun Seung Huh | 2013 | World Journal of Gastroenterology2013,19,30: | 15 |
| 5 | 术前肌电图和脑干听觉诱发电位与面肌痉挛微血管减压术后迟发性面瘫发生的关系(英文)显示文摘Background Delayed facial palsy ( DFP) after microvascular decompression ( MVD) in patients with hemifacial spasm ( HFS) is not uncommon,but the cause remains unknown. Objectives To assess whether intraoperative electromyography ( EMG) and brainstem auditory evoked potential ( BAEP) can predict DFP after MVD. Methods Between September 2009 and February 2011 we examined 86 patients,9 of whom ( 10. 4% ) developed DFP after MVD on the same side. All patients underwent MVD and were followed - up for a median period of 13 months ( range 6-22) . We retrospectively examined intraoperative facial EMG and BAEP findings using our MVD patients' registry. We excluded secondary HFS and immediate postoperative facial palsy after MVD in this study. We assessed the prevalence and clinical characteristics of DFP and compared EMG and BAEP findings between DFP and non-DFP groups. Results: All pa- tients recovered completely,with a mean time to recovery of 37. 8 days ( range 22-57) . There were no significant differences between DFP and non - DFP patients in terms of the amplitude and latency of intraoperative EMG and BAEP. Conclusion The usefulness of intraoperative facial EMG and BAEP is limited and cannot predict DFP after MVD for HFS. We speculate that DFP after MVD is not associated with permanent nerve damage according to the EMG findings. | Kim HJ Park YS Ryu JS Huh R Han I Shin DA Kim TG Cho KG Chung SS | 2012 | 中华神经外科疾病研究杂志2012,11,4: | 13 |
| 6 | Interactomic study on interaction between lipid droplets and mitochondria显示文摘An increasing body of evidence shows that the lipid droplet,a neutral lipid storage organelle,plays a role in lipid metabolism and energy homeostasis through its interaction with mitochondria.However,the cellular functions and molecular mechanisms of the interaction remain ambiguous.Here we present data from transmission electron microscopy,fluorescence imaging,and reconstitution assays,demonstrating that lipid droplets physically contact mitochondria in vivo and in vitro.Using a bimolecular fluorescence complementation assay in Saccharomyces cerevisiae,we generated an interactomic map of protein-protein contacts of lipid droplets with mitochondria and peroxisomes.The lipid droplet proteins Erg6 and Pet10 were found to be involved in 75%of the interactions detected.Interestingly,interactions between 3 pairs of lipid metabolic enzymes were detected.Collectively,these data demonstrate that lipid droplets make physical contacts with mitochondria and peroxisomes,and reveal specific molecular interactions that suggest active participation of lipid droplets in lipid metabolism in yeast. | Jing Pu Cheol Woong Ha Shuyan Zhang Jong Pil Jung Won-Ki Huh Pingsheng Liu | 2011 | Protein & Cell2011,2,6: | 9 |
| 7 | Cavity noise sensitivity analysis of tire contour design factors and application of contour optimization methodology显示文摘Cavity resonance noise of passenger car tires is generated by interacting excitation between a tire structure and the fill gas (air), and generally lies in a frequency range of 200?250 Hz. As such, this noise is strongly perceived and may be a serious source of driver annoyance. Thus, many studies regarding the cavity noise mechanism and its reduction have already been conducted. In this work, a vibro-acoustic coupled analysis was conducted between a tire structure and air cavity. Using this analysis, we can more accurately simulate the tire noise performance in the region of the cavity resonance frequency. An analysis of the effects of variation of tire contour design factors was conducted, using design-of-experiments methods. Finally, a multi-objective optimization was performed using in-house codes to reduce the cavity noise level while minimizing the loss of other performances, such as diminished ride comfort and handling caused by the variations of contour. As a result of this optimization, an optimized contour shape was derived, which satisfied the multi-objective performances. | KIM Seong-rae SUNG Ki-deug LEE Dong-woo HUH Sun-chul | 2012 | Journal of Central South University2012,19,8: | 7 |
| 8 | Differential diagnosis of left-sided abdominal pain:Primary epiploic appendagitis vs colonic diverticulitis显示文摘AIM:To investigate the clinical characteristics of left primary epiploic appendagitis and to compare them with those of left colonic diverticulitis.METHODS:We retrospectively reviewed the clinical records and radiologic images of the patients who presented with left-sided acute abdominal pain and had computer tomography(CT) performed at the time of presentation showing radiological signs of left primary epiploic appendagitis(PEA) or left acute colonic diverticulitis(ACD) between January 2001 and December 2011. A total of 53 consecutive patients were enrolled and evaluated. We also compared the clinical characteristics,laboratory findings,treatments,and clinical results of left PEA with those of left ACD.RESULTS:Twenty-eight patients and twenty-five patients were diagnosed with symptomatic left PEA and ACD,respectively. The patients with left PEA had focal abdominal tenderness on the left lower quadrant(82.1%). On CT examination,most(89.3%) of the patients with left PEA were found to have an oval fatty mass with a hyperattenuated ring sign. In cases of left ACD,the patients presented with a more diffuse abdominal tenderness throughout the left side(52.0%vs 14.3%; P = 0.003). The patients with left ACD had fever and rebound tenderness more often than those with left PEA(40.0% vs 7.1%,P = 0.004; 52.0% vs14.3%,P = 0.003,respectively). Laboratory abnormalities such as leukocytosis were also more frequently observed in left ACD(52.0% vs 15.4%,P = 0.006).CONCLUSION:If patients have left-sided localized abdominal pain without associated symptoms or laboratory abnormalities,clinicians should suspect the diagnosis of PEA and consider a CT scan. | Jeong Ah Hwang Sun Moon Kim Hyun Jung Song Yu Mi Lee Kyung Min Moon Chang Gi Moon Hoon Sup Koo Kyung Ho Song Yong Seok Kim Tae Hee Lee Kyu Chan Huh Young Woo Choi Young Woo Kang Woo Suk Chung | 2013 | World Journal of Gastroenterology2013,19,40: | 6 |
| 9 | Controlling hypoxia-inducible factor-2α is critical for maintaining bone homeostasis in mice显示文摘Pathological bone loss is caused by an imbalance between bone formation and resorption.The bone microenvironments are hypoxic,and hypoxia-inducible factor (HIF) is known to play notable roles in bone remodeling.However,the relevant functions of HIF-2α are not well understood.Here,we have shown that HIF-2α deficiency in mice enhances bone mass through its effects on the differentiation of osteoblasts and osteoclasts.In vitro analyses revealed that HIF-2α inhibits osteoblast differentiation by targeting Twist2 and stimulates RANKL-induced osteoclastogenesis via regulation of Traf6.In addition,HIF-2α appears to contribute to the crosstalk between osteoblasts and osteoclasts by directly targeting RANKL in osteoprogenitor cells.Experiments performed with osteoblast- and osteoclast-specific conditional knockout mice supported a role of HIF-2α in this crosstalk.HIF-2α deficiency alleviated ovariectomy-induced bone loss in mice,and specific inhibition of HIF-2α with ZINC04179524 significantly blocked RANKLmediated osteoclastogenesis.Collectively,our results suggest that HIF-2α functions as a catabolic regulator in bone remodeling,which is critical for the maintenance of bone homeostasis. | Sun Young Lee Ka Hyon Park Hyung-Gu Yu Eunbyul Kook Won-Hyun Song Gyuseok Lee Jeong-Tae Koh Hong-In Shin Je-Yong Choi Yun Hyun Huh Je-Hwang Ryu | 2019 | Bone Research2019,7,2: | 5 |

| 11 | Endoscopic ultrasonography-guided trucut biopsy for the preoperative diagnosis of peripancreatic castleman's disease: A case report显示文摘Castleman's disease (CD) of the pancreas/peripancreas is extremely rare. The recently introduced, endoscopic ultrasonography (EUS)-guided trucut biopsy (TCB) is a useful diagnostic modality for obtaining tissue samples from peripancreatic lesions. However, its role in diagnosing CD remains unknown. We report a case of localized, peripancreatic, hyaline-vascular CD biopsied using EUS. The pathology results were initially interpreted as an extranodal, marginal-zone B-cell lymphoma. However, polymerase chain reaction (PCR) study for the IgH gene rearrangement revealed a polyclonal pattern. We also reviewed the relevant literature. To our knowledge, this is the first illustrated report on EUS-TCB findings of CD with its pathology results of EUS-TCB mimicked a B-cell lymphoma. | Kyoung Hoon Rhee Sang Soo Lee Joo Ryung Huh | 2008 | World Journal of Gastroenterology2008,14,13: | 5 |
| 12 | Towards efficient data exchange and sharing for big-data driven materials science:metadata and data formats显示文摘With big-data driven materials research,the new paradigm of materials science,sharing and wide accessibility of data are becoming crucial aspects.Obviously,a prerequisite for data exchange and big-data analytics is standardization,which means using consistent and unique conventions for,e.g.,units,zero base lines,and file formats.There are two main strategies to achieve this goal.One accepts the heterogeneous nature of the community,which comprises scientists from physics,chemistry,bio-physics,and materials science,by complying with the diverse ecosystem of computer codes and thus develops“converters”for the input and output files of all important codes.These converters then translate the data of each code into a standardized,codeindependent format.The other strategy is to provide standardized open libraries that code developers can adopt for shaping their inputs,outputs,and restart files,directly into the same code-independent format.In this perspective paper,we present both strategies and argue that they can and should be regarded as complementary,if not even synergetic.The represented appropriate format and conventions were agreed upon by two teams,the Electronic Structure Library(ESL)of the European Center for Atomic and Molecular Computations(CECAM)and the NOvel MAterials Discovery(NOMAD)Laboratory,a European Centre of Excellence(CoE).A key element of this work is the definition of hierarchical metadata describing state-of-the-art electronic-structure calculations. | Luca M.Ghiringhelli Christian Carbogno Sergey Levchenko Fawzi Mohamed Georg Huhs Martin Luders Micael Oliveira Matthias Scheffler | 2017 | npj Computational Materials2017,,1: | 5 |
| 13 | EVALUATION OF DUCTILE FRACTURE CRITERIA IN A GENERAL THREE-DIMENSIONAL STRESS STATE CONSIDERING THE STRESS TRIAXIALITY AND THE LODE PARAMETER显示文摘This paper is concerned with evaluation of various ductile fracture criteria in a general three-dimensional stress state of stress triaxiality,the Lode parameter and the equivalent plastic strain to fracture.Evaluation is carried out by comparing fracture loci constructed by fracture criteria to experimental results of Al2024-T351.Comparison demonstrates that the Modified Mohr-Coulomb criterion and a newly proposed criterion provide sufcient predictability of fracture strain.Moreover,evaluation is emphasized on the predicted cut-of value for stress triaxiality.The evaluation demonstrates that the Cockcroft-Latham,Brozzo,Oh,Ko-Huh and the new criteria coupled a reasonable cut-of value for ductile materials. | Yanshan Lou Hoon Huh | 2013 | Acta Mechanica Solida Sinica2013,26,6: | 5 |
| 14 | An experimental study on thermal characteristics of nanofluid with graphene and multi-wall carbon nanotubes显示文摘High-thermal conductivity enhancement of nanofluid is one of the promising topics of the nanoscience research field. This work reports the experimental study on the preparation of graphene(GN) and multi-walled carbon nanotubes(MWCNTs) based nanofluids with the assistance of sodium dodecyl benzene sulfonate(SDBS) and sodium dodecyl sulfate(SDS) surfactants, and their thermal behaviors. The present work suggests not a solution, but a solution approach and deduces a new conclusion by trying to resolve the agglomeration problem and improve the dispersibility of nanoparticles in the base fluid. The analysis results of FESEM, thermal conductivity, diffusivity, effusivity and heat transfer coefficient enhancement ratio of nanofluid with surfactants SDS and SDBS expose strong evidence of the dispersing effect of surfactant on the making of nanofluid. | A.K.M Mahmudul Haque Sunghyun Kwon Junhyo Kim Jungpil Noh Sunchul Huh Hanshik Chung Hyomin Jeong | 2015 | Journal of Central South University2015,22,8: | 5 |
| 15 | Dual probiotic strains suppress high fructose-induced metabolic syndrome显示文摘AIM:To investigate the effect of novel probiotics on the clinical characteristics of high-fructose induced metabolic syndrome.METHODS:Male Wistar rats aged 4 wk were fed a 70% w/w high-fructose diet(n = 27) or chow diet(n = 9) for 3 wk to induce metabolic syndrome,the rats were then randomized into groups and administered probiotic [Lactobacillus curvatus(L.curvatus) HY7601 and Lactobacillus plantarum(L.plantarum) KY1032] at 109 cfu/d or 1010 cfu/d or placebo by oral gavage for 3 wk.Food intake and body weight were measured once a week.After 6 wk,the rats were fasted for 12 h,then anesthetized with diethyl ether and sacrificed.Blood samples were taken from the inferior vena cava for plasma analysis of glucose,insulin,C-peptide,totalcholesterol,triglycerides and thiobarbituric acid-reacting substances.Real-time polymerase chain reaction was performed using mouse-specific Taqman probe sets to assess genes related to fatty acid β-oxidation,lipogenesis and cholesterol metabolism in the liver.Target gene expression was normalized to the housekeeping gene,glyceraldehyde-3-phosphate dehydrogenase.RESULTS:Rodents fed a high-fructose diet developed clinical characteristics of the metabolic syndrome including increased plasma glucose,insulin,triglycerides,total cholesterol and oxidative stress levels,as well as increased liver mass and liver lipids compared to chow fed controls.Probiotic treatment(L.curvatus HY7601 and L.plantarum KY1032) at high(1010 cfu/d) or low dosage(109 cfu/d) lowered plasma glucose,insulin,triglycerides and oxidative stress levels.Only high-dose probiotic treatment reduced liver mass and liver cholesterol.Probiotic treatment reduced lipogenesis via downregulation of SREBP1,FAS and SCD1 mRNA levels and increased β-oxidation via up-regulation of PPARα and CPT2 mRNA levels.CONCLUSION:Probiotic L.curvatus HY7601 and L.plantarum KY1032 combined suppressed the clinical characteristics of high-fructose-induced metabolic syndrome,therefore,may provide a natural alternative for the treatment of diet-induced metabolic syndrome. | Do-Young Park Young-Tae Ahn Chul-Sung Huh Robin A McGregor Myung-Sook Choi | 2013 | World Journal of Gastroenterology2013,19,2: | 5 |
| 16 | Emamectin benzoate 9.7%SL as a new formulation for a trunkinjections against pine wood nematode,Bursaphelenchus xylophilus显示文摘In this study,we investigated the preventive effects of emamectin benzoate 9.7%SL,which was newly developed to reduce the injection volume and number of injection holes required to protect against pine wood nematode.None of the Pinus thunbergii trees injected with emamectin benzoate 9.7%SL at 0.3 mL/cm diameter at breast height(DBH)died within 2 years of inoculation with pine wood nematodes.Emamectin benzoate 9.7%SL injected at 0.6 mL/cm DBH resulted in no tree mortality for 3 years.Mean residue of emamectin benzoate 9.7%SL in pine twigs injected with 0.3 mL/cm DBH was 0.490μg/g at 1 year after injection and 0.303μg/g after 2 years.These residues values are greater than 0.031μg/g,previously determined IC95 value for emamectin benzoate against the pine wood nematode.Our field experiment and residue analysis showed that emamectin benzoate 9.7%SL could be a substitute agent for emamectin benzoate 2.15%EC,which is widely used to prevent pine wood nematode in the field and that injection volume and number of injection holes can be greatly educed using this new formulation,which will reduce injury to the cambium,interruption of water movement,and infection of inoculation wounds by wood-decay or blue stain fungi. | Sung-Chan Lee Hyo-Rim Lee Dong-Soo Kim Jun-Hyeong Kwon Min-Jung Huh Il-Kwon Park | 2020 | Journal of Forestry Research2020,31,4: | 3 |
| 17 | Fabrication of SAW Sensor for Detecting Chemical Agent显示文摘SAW sensors using five different types of polymer to detect of chemical agents(DMMP,CH_3CN,CH_2Cl_2,DCP) have been fabricated and its gas response characteristics were extensively investigated.The polymers used as the sensing material are polyisobutylene(PIB),polyepichlorohydrin(PECH),polydimethylsiloxane(PDMS),polyisoprene(PIP)and polybutadiene(PBD).Their thin films were coated on quartz substrate by spin coating technique.Three types of simulants gases,dimethylmethylphosphonate(DMMP),acetonitrile(CH_3CN)and dichloromethane(CH_2Cl_2),dichloropentane(DCP)were used as target gases,instead of the real nerve,blood,choking and vesicant agents.After spin coating of PIB and PECH,the substrates were heated to 65℃with N_2 flow for 1 h to remove the cyclohexane and ethylacetate which was used as solvent. PDMS was heated to 75℃with N_2 flow for 2 h to remove the ethylacetate which was used as solvent.PBD and PIP on the substrate were heated to 60℃with N_2 flow for 1 h to remove the benzen which was used as solvent.The sensing characteristics of the SAW sensors were measured by using E-5061A network analyzer. | J H Lee B S Joo J S Huh D D Lee | 2006 | 稀有金属材料与工程2006,35,A03: | 3 |
| 18 | Studies on self-esteem of penile size in young Koreanmilitary men显示文摘Aim:To investigate the flaccid and stretched penile sizes of young Korean men and their complexes or pride about their penile size. Methods: After an explanation and agreement to the purpose and methods of this study,123 Korean men in their early 20's visiting the Jinhae Military General Hospital were included in the study. The flaccid penile length, flaccid mid-shaft circumference, stretched length and pre-pubic bone fat pad depth were measured in a warm comfortable environment. The accuracy the subjects assessed their penile size was investigated by asking them to rate their penile size, as ‘very small', ‘small', ‘normal', ‘large' or ‘very large'. All subjects were asked to completethe Minnesota multiphasic personality inventory (MMPI) test. Results: The mean flaccid length, flaccid cireumfereace,stretched length and fat pad depth of the 123 subjects were (6.9 ± 0.8) cm, (8.5 ± 1.1) cm, (9.6± 0.8) cm and (1.1± 0.4) cm, respectively. The answer distribution on penile size was 1 (0.8 %) ‘very small', 29 (23.6 %) ‘small', 86(69.9 %) ‘normal', 6 (4.9 %) ‘large' and 1 (0.8 %)‘'very large'. Subjects who underestimated their penile size showed significantly higher scores on the hypochondriasis (Hs), depression (D) and psychasthenia (Pt) subscales of the MMPI than those in the Unbiased Group (P<0.05). Conclusion: In consultation, with a patient requesting penile augmentation, the urologist should consider the psychologic attitude of the patient to his penile size.
