| 1 | Developing a donation after cardiac death risk index for adult and pediatric liver transplantation显示文摘AIM To identify objective predictive factors for donor after cardiac death(DCD) graft loss and using those factors, develop a donor recipient stratification risk predictive model that could be used to calculate a DCD risk index(DCD-RI) to help in prospective decision making on organ use.METHODS The model included objective data from a single institute DCD database(2005-2013, n = 261). Univariate survival analysis was followed by adjusted Cox-regressional hazard model. Covariates selected via univariate regression were added to the model via forward selection, significance level P = 0.3. The warm ischemic threshold was clinically set at 30 min. Points were given to each predictor in proportion to their hazard ratio. Using this model, the DCD-RI was calculated. The cohort was stratified to predict graft loss risk and respective graft survival calculated.RESULTS DCD graft survival predictors were primary indication for transplant(P = 0.066), retransplantation(P = 0.176), MELD > 25(P = 0.05), cold ischemia > 10 h(P = 0.292) and donor hepatectomy time > 60 min(P = 0.028).According to the calculated DCD-RI score three risk classes could be defined of low(DCD-RI < 1), standard(DCD-RI 2-4) and high risk(DCD-RI > 5) with a 5 years graft survival of 86%, 78% and 34%, respectively.CONCLUSION The DCD-RI score independently predicted graft loss(P < 0.001) and the DCD-RI class predicted graft survival(P < 0.001). | Shirin Elizabeth Khorsandi Emmanouil Giorgakis Hector Vilca-Melendez John O'Grady Michael Heneghan Varuna Aluvihare Abid Suddle Kosh Agarwal Krishna Menon Andreas Prachalias Parthi Srinivasan Mohamed Rela Wayel Jassem Nigel Heaton | 2017 | World Journal of Transplantation2017，7，3： | 3 |

| 9 | Evaluating the Efficiency of Cadmium Removal by Alginate Hydrogels from Water Using 5,7-Dibromo-8-hydroxyquinoline as a Complexing Reagent显示文摘Cadmium toxicity in wastewater is a rising concern due to industries like batteries,metallurgy,electroplating,plastic stabilizers,and pigments.The quantitative detection of Cd^(2+)and its remediation from wastewater samples are of major concern from an environmental point of view.In the present work,an effective spectrophotometric method has been reported using 5,7-dibromo-8-hydroxyquinoline(DBHQ)as a complexing agent for Cd^(2+).This method has advantages like using recyclable,less toxic solvents and easy sample preparation.The limit of detection,limit of quantification,and sensitivity of the proposed method were found to be 33.30,36.70 mg L^(−1),and 2×10^(−3),respectively.The DBHQ method was validated using atomic absorption spectroscopy,and the recovery percentage was more than 98%.These results indicate that DBHQ can be effectively used for monitoring Cd^(2+)in aqueous systems.The method developed was further employed for monitoring Cd^(2+)adsorption on calcium alginate(AL)hydrogels.Batch adsorption studies were done to optimize parameters of Cd^(2+)removal using AL hydrogels,and the data obtained were used for kinetic and thermodynamic studies.Kinetic studies indicated that the pseudo-first-order model showed better fitting,and thermodynamic studies showed Freundlich-like adsorption.The maximum adsorption capacity of Cd^(2+)on AL hydrogels was found to be 56.45 mg g^(−1).The validation studies of DBHQ were performed using statistical analysis methods like t-tests and one-way variance. | Abhijit B.Phalke Varuna S.Watwe Sunil D.Kulkarni Preeti S.Kulkarni | 2023 | Precision Chemistry2023，1，9： | 0 |
