| 1 | Percutaneous nephrolithotomy for staghorn calculi: Troubleshooting and managing complications显示文摘Staghorn calculi comprise a unique subset of complex kidney stone disease. Percutaneousnephrolithotomy (PCNL) is the gold standard treatment for staghorn stones. Despitecontinuous refinements to the technique and instrumentation of PCNL, these stones remaina troublesome challenge for endourologists and are associated with a higher rate of perioperativecomplications than that for non-staghorn stones. Common and notable intraoperativecomplications include bleeding, renal collecting system injury, injury of visceral organs, pulmonarycomplications, thromboembolic complications, extrarenal stone migration, andmisplacement of the nephrostomy tube. Postoperative complications include infection and urosepsis,bleeding, persistent nephrocutaneous urine leakage, infundibular stenosis, and death.In this review, we report recommendations regarding troubleshooting measures that can beused to identify and characterize these complications. Additionally, we include informationregarding management strategies for complications associated with PCNL for staghorn calculi. | Nariman Gadzhiev Vigen Malkhasyan Gagik Akopyan Sergei Petrov Francis Jefferson Zhamshid Okhunov | 2020 | Asian Journal of Urology2020，7，2： | 11 |

| 11 | Singlet relaxation dynamics and long triplet lifetimes of thiophene-coupled perylene diimides dyads:New insights for high efficiency organic solar cells显示文摘In the active layer of organic solar cells(OSCs),the lifetime of triplet excitons is one of the decisive factors in the diffusion length and therefore has important impact on the power conversion efficiency of the devices.Herein,we have investigated singlet excited state relaxation dynamics and their triplet exciton lifetimes of two thiophene-coupled perylene diimides(PDI)dyads(2 PDI-Th and fused-2 PDI-Th),in order to provide a unique explanation in depth on their different performances in OSC devices.From the transient absorption(TA)spectra,the singlet excitons of 2 PDI-Th form excimers in the time scale of 1.5 ps.Then the excimers go into the triplet state via intersystem crossing(ISC).In fused-2 PDI-Th,triplet excitons are generated directly from the singlet excited excitons via the efficient ISC.Density functional theory(DFT)calculations further support the formation of excimers.DFT results indicate that 2 PDI-Th exhibits an H-typed molecular configuration which is beneficial to form the excimers,while fused-2 PDITh gives a twisted X-shaped configuration in the optimized ground and excited state.In steady-state emission spectra,2 PDI-Th shows abroad and featureless spectral characteristics of the excimers with a decay time of 840 ps,which is much shorter than those of PDI(5.5 ns)and fused-2 PDI-Th(3.3 ns).The triplet lifetime(67 ms)of fused-2 PDI-Th is factor of 3 longer than that of 2 PDI-Th(22 ms).These results demonstrate that ring-fused structure is an efficient strategy to eliminate excimer formation and prolong the lifetime of triplet excitons,which provides a new insight for design of optoelectronic molecules for high efficiency organic solar cells. | Qingxuan Fan Wenjun Ni Lingcheng Chen Gagik G.Gurzadyan Yi Xiao | 2020 | Chinese Chemical Letters2020，31，11： | 0 |
| 12 | Coil embolization of arterioportal fistula complicated by gastrointestinal bleeding after Caesarian section: A case report显示文摘BACKGROUND Most intrahepatic arterioportal fistulae(IAPF)are acquired.The few cases of congenital fistulae are diagnosed in infants and children.CASE SUMMARY We report a 31-year-old female patient presenting with haematemesis and melena three weeks after delivering her second child.The patient had a 20-year history of abdominal distention and nausea.IAPF,along with splenomegaly and ascites,was found by Doppler sonography and confirmed by computed tomography angiography.The patient was treated with endovascular coil embolization,resulting in occlusion of the fistula.CONCLUSION This was an unusual case of possible congenital IAPF that manifested during a second pregnancy and was complicated by portal hypertension. | Suren Agho Stepanyan Tigran Poghosyan Karen Manukyan Gagik Hakobyan Hayk Hovhannisyan Hayk Safaryan Elena Baghdasaryan Manik Gemilyan | 2021 | World Journal of Clinical Cases2021，9，2： | 0 |
| 13 | Manipulation of successive crystalline transformations to control electron transfer and switchable functions显示文摘Electron transfer in solid is crucial to switchable magnetic,electrical,optical and mechanical properties.However,it is a formidable challenge to control electron-transfer behaviors via manipulation of crystalline phases,especially through dynamic crystalline transformation.Herein,three crystalline phases of an{Fe_2Co_2}compound were obtained via enhancement of intermolecularπ···πinteractions inducingsuccessive single-crystal-to-single-crystal transformations,from solvated 1·2CH_3OH·4H_2O,to desolvated1 and its polymorph 1a accompanying electron transfer.1·2CH_3OH·4H_2O showed thermally inducedreversible intermetallic electron transfer in mother liquor.No electron-transfer behavior was observed in 1.1a showed reversible intermetallic electron transfer upon thermal treatment or alternative irradiation with808-and 532-nm lasers at cryogenic temperatures.The electron-transfer behaviors significantly change the magnetic and optical properties,providing a strategy to realize different electron-transfer behaviors andswitchable functions viaπ···πinteractions manipulated dynamic crystalline transformation. | Cheng-Qi Jiao Wen-Jing Jiang Yin-Shan Meng Wen Wen Liang Zhao Jun-Li Wang Ji-Xiang Hu Gagik G.Gurzadyan Chun-Ying Duan Tao Liu | 2018 | National Science Review2018，5，4： | 0 |
