| 1 | Effect of trapping vascular endothelial growth factor-A in a murine model of dry eye with inflammatory neovascularization显示文摘·AIM: To evaluate whether trapping vascular endothelial growth factor-A(VEGF-A) would suppress angiogenesis and inflammation in dry eye corneas in a murine corneal suture model.·METHODS: We established two groups of animals, one with non-dry eyes and the other with induced dry eyes.In both groups, a corneal suture model was used to induce inflammation and neovascularization. Each of two groups was again divided into three subgroups according to the treatment; subgroup I(aflibercept),subgroup II(dexamethasone) and subgroup III(phosphate buffered saline, PBS). Corneas were harvested and immunohistochemical staining was performed to compare the extents of neovascularization and CD11b+ cell infiltration. Real-time polymerase chain reaction was performed to quantify the expression of inflammatory cytokines and VEGF-A in the corneas.·RESULTS: Trapping VEGF-A with aflibercept resulted in significantly decreased angiogenesis and inflammation compared with the dexamethasone and PBS treatments in the dry eye corneas(all P <0.05), but with no such effects in non-dry eyes. The anti-inflammatory and antiangiogenic effects of VEGF-A trapping were stronger than those of dexamethasone in both dry eye and non-dry eye corneas(all P <0.05). The levels of RNA expression of VEGF-A, TNF-alpha, and IL-6 in the aflibercept subgroup were significantly decreasedcompared with those in the PBS subgroup in the dry eye group.·CONCLUSION: Compared with non-dry eye corneas,dry eye corneas have greater amounts of inflammation and neovascularization and also have a more robust response to anti-inflammatory and anti-angiogenic agents after ocular surface surgery. Trapping VEGF-A is effective in decreasing both angiogenesis and inflammation in dry eye corneas after ocular surface surgery. | Jin Woo Kwon Jin A Choi Eun Young Shin Tae Yoon La Dong Hyun Jee Yeon Woong Chung Yang Kyung Cho | 2016 | International Journal of Ophthalmology(English edition)2016，9，11： | 5 |
| 2 | Comparison of postoperative corneal changes between dry eye and non-dry eye in a murine cataract surgery model显示文摘AIM: To compare the effects of the surgical insult of cataract surgery on corneal inflammatory infiltration,neovascularization(NV) and lymphangiogenesis(LY)between the dry eye and non-dry eye in murine cataract surgery models.·METHODS: We established two groups of animals, one with normal eyes(non-dry eye) and the second with induced dry eyes. In both groups, we used surgical insults to mimic human cataract surgery, which consisted of lens extraction, corneal incision and suture.After harvesting of corneas on the 9th postoperative day and immunohistochemical staining, we compared NV, LY and CD11b+ cell infiltration in the corneas.· RESULTS: Dry eye group had significantly more inflammatory infiltration(21.75%±7.17% vs 3.65%±1.49%;P =0.049). The dry eye group showed significantly more NV(48.21% ±4.02% vs 26.24% ±6.01%; P =0.016) and greater levels of LY(9.27%±0.48% vs 4.84%±1.15%; P =0.007). In corneas on which no surgery was performed,there was no induction of NV in both the dry and non-dry group, but dry eye group demonstrated more CD11b+cells infiltration than the non-dry eye group(0.360% ±0.160% vs 0.023% ±0.006%; P =0.068). Dry eye group showed more NV than non-dry eye group in both topical PBS application and subconjunctival PBS injection(P =0.020 and 0.000, respectively).·CONCLUSION: In a murine cataract surgery model,preexisting dry eye can induce more postoperative NV,LY, and inflammation in corneal tissue. | Jin Woo Kwon Yeon Woong Chung Jin A Choi Tae Yoon La Dong Hyun Jee Yang Kyung Cho | 2016 | International Journal of Ophthalmology(English edition)2016，9，2： | 5 |
| 3 | A case of hypereosinophilic syndrome presenting with intractable gastric ulcers显示文摘We report a rare case of hypereosinophilic syndrome(HES)presenting with intractable gastric ulcers.A 71-year-old man was admitted with epigastric pain.Initial endoscopic findings revealed multiple,active gastric ulcers in the gastric antrum.He underwent Helicobacter pylori(H pylori)eradication therapy followed by proton pump inhibitor(PPI)therapy.However,follow-up endoscopy at 4,6,10 and 14 mo revealed persistent multiple gastric ulcers without significant improvement.The proportion of his eosinophil count increased to 43%(total count:7903/mm 3).Abdominal-pelvic and chest computed tomography scans showed multiple small nodules in the liver and both lungs.The endoscopic biopsy specimen taken from the gastric antrum revealed prominent eosinophilic infiltration,and the liver biopsy specimen also showed eosinophilic infiltration in the portal tract and sinusoid.A bone marrow biopsy disclosed eosinophilic hyperplasia as well as increased cellularity of 70%.The patient was finally diagnosed with HES involving the stomach,liver,lung,and bone marrow.When gastric ulcers do not improve despite H pylori eradication and prolonged PPI therapy,infiltrative gastric disorders such as HES should be considered. | Tae Young Park Chang Hwan Choi Suh Yoon Yang InSoo Oh In-Do Song Hyun Woong Lee Hyung Joon Kim Jae Hyuk Do Sae Kyung Chang Ah Ra Cho Young Joo Cha | 2009 | World Journal of Gastroenterology2009，15，48： | 2 |

| 7 | Highly Elastic,Bioresorbable Polymeric Materials for Stretchable,Transient Electronic Systems显示文摘Substrates or encapsulants in soft and stretchable formats are key components for transient,bioresorbable electronic systems;however,elastomeric polymers with desired mechanical and biochemical properties are very limited compared to nontransient counterparts.Here,we introduce a bioresorbable elastomer,poly(glycolide-co-ε-caprolactone)(PGCL),that contains excellent material properties including high elongation-at-break(<1300%),resilience and toughness,and tunable dissolution behaviors.Exploitation of PGCLs as polymer matrices,in combination with conducing polymers,yields stretchable,conductive composites for degradable interconnects,sensors,and actuators,which can reliably function under external strains.Integration of device components with wireless modules demonstrates elastic,transient electronic suture system with on-demand drug delivery for rapid recovery of postsurgical wounds in soft,time-dynamic tissues. | Jeong‑Woong Shin Dong‑Je Kim Tae‑Min Jang Won Bae Han Joong Hoon Lee Gwan‑Jin Ko Seung Min Yang Kaveti Rajaram Sungkeun Han Heeseok Kang Jun Hyeon Lim Chan‑Hwi Eom Amay J.Bandodkar Hanul Min Suk‑Won Hwang | 2024 | Nano-Micro Letters2024，16，6： | 0 |
| 8 | Cardiac rehabilitation in a heart failure patient after left ventricular assist device insertion and subsequent heart transplantation:A case report显示文摘BACKGROUND Insertion of a left ventricular assist device(LVAD)and heart transplantation(HT)improve the survival of patients with heart failure.In addition,cardiac rehabilitation(CR)further increases the functional capacity.This case report describes a successful case of CR after LVAD insertion and subsequent HT.CASE SUMMARY In the present case,during the LVAD insertion period,peak oxygen consumption(VO2)increased by 12.16%after CR.HT was performed 7 mo after the LVAD insertion,and the patient participated in phases I and II CR.The peak VO2 increased from 17.24 to 22.29 m L/kg/min.This improvement was more significant than that reported in previous studies on CR after LVAD insertion or HT.The patient’s quality of life also improved.The total average score of the short form-36 questionnaire increased from 29.5 points at admission to 53.3 points 9 mo after HT.CONCLUSION A tailored CR program after LVAD insertion or HT may improve the patients’quality of life and increase survival. | Tae Woong Yang Seunghwan Song Hye Won Lee Byeong-Ju Lee | 2022 | World Journal of Clinical Cases2022，10，8： | 0 |
| 9 | Surface-functionalized hole-selective monolayer for high efficiency single-junction wide-bandgap and monolithic tandem perovskite solar cells显示文摘Carbazole moiety-based 2PACz([2-(9H-carbazol-9-yl)ethyl]phosphonic acid)self-assembled monolayers(SAMs)are excellent hole-selective contact(HSC)materials with abilities to excel the charge-transferdynamics of perovskite solar cells(PSCs).Herein,we report a facile but powerful method to functionalize the surface of 2PACz-SAM,by which reproducible,highly stable,high-efficiency wide-bandgap PSCs can be obtained.The 2PACz surface treatment with various donor number solvents improves assembly of 2PACz-SAM and leave residual surface-bound solvent molecules on 2PACz-SAM,which increases perovskite grain size,retards halide segregation,and accelerates hole extraction.The surface functionalization achieves a high power conversion efficiency(PCE)of 17.62%for a single-junction wide-bandgap(~1.77 e V)PSC.We also demonstrate a monolithic all-perovskite tandem solar cell using surfaceengineered HSC,showing high PCE of 24.66%with large open-circuit voltage of 2.008 V and high fillfactor of 81.45%.Our results suggest this simple approach can further improve the tandem device,when coupled with a high-performance narrow-bandgap sub-cell. | Devthade Vidyasagar Yeonghun Yun Jae Yu Cho Hyemin Lee Kyung Won Kim Yong Tae Kim Sung Woong Yang Jina Jung Won Chang Choi Seonu Kim Rajendra Kumar Gunasekaran Seok Beom Kang Kwang Heo Dong Hoe Kim Jaeyeong Heo Sangwook Lee | 2024 | Journal of Energy Chemistry2024，88，1： | 0 |
| 10 | Oxygen vacancy engineering for tuning the catalytic activity of LaCoO_(3) perovskite显示文摘Herein, we attempted to engineer oxygen vacancies on the surface of LaCoO_(3) perovskite through simple post-treatments(acid or reductive thermal treatments). Acid treatment induces oxygen vacancies through the selective etching of the La cations, whereas thermal treatment in a reducing atmosphere generates oxygen vacancies by directly removing lattice oxygen. The characterization results confirm that the number of surface oxygen vacancies, which are crucial in various catalytic oxidation reactions,considerably increases in the LaCoO_(3) catalysts treated with acid or reducing gas. Acid treatment enriches the oxygen vacancies while maintaining the structure of the LaCoO_(3) catalysts, which can not be achieved through reductive thermal treatment. Therefore, the acid treatment is considered a promising technique for oxygen vacancy engineering of perovskite catalysts for tuning their catalytic activities. Furthermore,the catalytic activities of the posttreated LaCoO_(3) catalysts for CO oxidation were evaluated and are noted to be considerably better than those of the pristine LaCoO_(3) catalyst due to their abundant oxygen vacancies. Consequently, we conclude that the oxygen vacancies of perovskite catalysts can be effectively engineered via two simple methods and play a significant role in CO oxidation. | Jeong Hyun Cho Minjae Kim Inchan Yang Kyung Tae Park Chang Houn Rhee Hai Woong Park Ji Chul Jung | 2024 | Journal of Rare Earths2024，42，3： | 0 |
