| 1 | Personal Review:Sources of sulfide in waste streams and current biotechnologies for its removal显示文摘Sulfide-containing waste streams are generated by a number of industries. It is emitted into the environment as dis- solved sulfide (S2- and HS-) in wastewaters and as H2S in waste gases. Due to its corrosive nature, biological hydrogen sulfide removal processes are being investigated to overcome the chemical and disposal costs associated with existing chemically based removal processes. The nitrogen and sulfur metabolism interacts at various levels of the wastewater treatment process. Hence, the sulfur cycle offers possibilities to integrate nitrogen removal in the treatment process, which needs to be further optimized by appropriate design of the reactor configuration, optimization of performance parameters, retention of biomass and optimization of biomass growth. The present paper reviews the biotechnological advances to remove sulfides from various environments. | MAHMOOD Qaisar ZHENG Ping CAI Jing HAYAT Yousaf HASSAN Muhammad Jaffar WU Dong-lei HU Bao-lan | 2007 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2007，8，7： | 22 |

| 9 | Discovering interlinkages between major cryptocurrencies using high‑frequency data: new evidence from COVID‑19 pandemic显示文摘Through the application of the VAR-AGARCH model to intra-day data for three cryptocurrencies(Bitcoin,Ethereum,and Litecoin),this study examines the return and volatility spillover between these cryptocurrencies during the pre-COVID-19 period and the COVID-19 period.We also estimate the optimal weights,hedge ratios,and hedging effectiveness during both sample periods.We find that the return spillovers vary across the two periods for the Bitcoin–Ethereum,Bitcoin–Litecoin,and Ethereum–Litecoin pairs.However,the volatility transmissions are found to be different during the two sample periods for the Bitcoin–Ethereum and Bitcoin–Litecoin pairs.The constant conditional correlations between all pairs of cryptocurrencies are observed to be higher during the COVID-19 period compared to the pre-COVID-19 period.Based on optimal weights,investors are advised to decrease their investments(a)in Bitcoin for the portfolios of Bitcoin/Ethereum and Bitcoin/Litecoin and(b)in Ethereum for the portfolios of Ethereum/Litecoin during the COVID-19 period.All hedge ratios are found to be higher during the COVID-19 period,implying a higher hedging cost compared to the pre-COVID-19 period.Last,the hedging effectiveness is higher during the COVID-19 period compared to the pre-COVID-19 period.Overall,these findings provide useful information to portfolio managers and policymakers regarding portfolio diversification,hedging,forecasting,and risk management. | Imran Yousaf Shoaib Ali | 2020 | Financial Innovation2020，6，1： | 4 |
| 10 | Splenic injuries secondary to colonoscopy:Rare but serious complication显示文摘BACKGROUND Colonoscopy is a safe and routine diagnostic and therapeutic procedure for evaluation of large bowel diseases.Most common procedure related complications include bleeding and perforation but rarely a splenic Injury.AIM To investigate the reason for colonoscopy,presentation of patient with spleen injury,types of injury,diagnosis,management and outcomes of patients METHODS A structured search on four databases was done and 45 articles with 68 patients were selected.The reason for colonoscopy,presentation of patient with spleen injury,types of injury,diagnosis,management and outcomes of patients were identified and analyzed using SPSS.RESULTS The mean age of the patients was 62.7 years with 64%females.Twenty two percent had a complete splenic rupture with colonoscopy while 63%had subcapsular hematoma,spleen laceration and spleen avulsion.The most common reason for colonoscopy was screening(46%)followed by diagnostic colonoscopy(28%).Eighty seven percent of patients presented with abdominal pain.Patients with spleen rupture mostly required splenectomy(47%),while minor spleen hematomas and lacerations were managed conservatively(38%).Six percent of the patients were managed with proximal splenic artery splenic embolization and 4%were managed with laparoscopic repair.The overall mortality was 10%while 77%had complete recovery.The reason of colonoscopy against presentation specifically,abdominal pain showed no statistical significance P=0.69.The indication of colonoscopy had no significant impact on incidence of splenic injury(P=0.89).Majority of the patients(47%)were managed with splenectomy while the rest were managed conservatively(P=0.04).This association was moderately strong at a cramer’s V test(0.34).The Fisher exact test showed a higher mortality with spleen rupture(P=0.028).CONCLUSION Spleen rupture due to colonoscopy is a significant concern and is associated with high mortality.The management of the patients can be individualized based on clinical presentation. | Waqas Ullah Mamoon Ur Rashid Asif Mehmood Yousaf Zafar Ishtiaq Hussain Deepika Sarvepalli Muhammad Khalid Hasan | 2020 | World Journal of Gastrointestinal Surgery2020，12，2： | 4 |
| 11 | Development of RP-HPLC method for simultaneous determination of docetaxel and curcumin in rat plasma: Validation and stability显示文摘The purpose of the present research was to develop a suitable, simple, precise, accurate,robust, and reproducible RP-HPLC method for a reliable simultaneous quantification of docetaxel(DTX) and curcumin(CCM) in rat plasma samples using paclitaxel(PTX) as an internal standard. The samples were assayed by the Agilent 1260 Infinity HPLC instrument using a Capcell Pak C8 column(4.6 mm × 150 mm, 5 μm) under isocratic conditions. The mobile phase consisted of acetonitrile and triple distilled water(40/60, v/v) with a flow rate of 1.0 ml/min. The eluent was monitored at 230 nm for simultaneous measurement of curcumin and docetaxel. The method was validated by determining system suitability, selectivity, sensitivity, linearity, inter-day and intra-day precision, accuracy, robustness, and stability in accordance with the guidelines of the United States Food and Drug Administration(FDA).The developed chromatographic method proved to be simple, precise, accurate, robust and reproducible. Moreover, the samples showed stability at room temperature over a period of 48 h. Thus, this method would be employed for routine simultaneous quantification of docetaxel and curcumin in rat plasma samples. | Dong Wuk Kim Abid Mehmood Yousaf Dong Xun Li Jong Oh Kim Chul Soon Yong Kwan Hyung Cho Han-Gon Choi | 2017 | Asian Journal of Pharmaceutical Sciences2017，12，1： | 3 |
| 12 | Silymarin-laden PVP-PEG polymeric composite for enhanced aqueous solubility and dissolution rate: Preparation and in vitro characterization显示文摘The aim of this work was to develop, optimize and characterize a silymarin-laden polyvinylpyrrolidone(PVP)-polyethylene glycol(PEG) polymeric composite to resolve low aqueous solubility and dissolution rate problem of the drug. A number of silymarin-laden polymeric formulations were fabricated with different quantities of PVP K-30 and PEG 6000 by the solvent-evaporation method. The effect of PVP K-30 and PEG 6000 on the aqueous solubility and dissolution rate was investigated. The optimized formulation and its constituents were characterized using powder X-ray diffraction(PXRD), differential scanning calorimetry(DSC), scanning electron microscopy(SEM) and Fourier transform infrared spectroscopy(FTIR) techniques. Both the PEG 6000 and PVP K-30 positively affected the aqueous solubility and dissolution rate of the drug. In particular, a formulation consisting of silymarin, PVP K-30 and PEG 6000(0.25/1.5/1.5, w/w/w) furnished the highest solubility(24.3972.95 mg/mL) and an excellent dissolution profile( $100% in 40 min). The solubility enhancement with this formulation was $ 1150-fold as compared to plain silymarin powder. Moreover, all the constituents existed in the amorphous state in this silymarin-laden PVP-PEG polymeric composite. Accordingly, this formulation might be a promising tool to administer silymarin with an enhanced effect via the oral route. | Abid Mehmood Yousaf Usman Rashid Malik Yasser Shahzad Tariq Mahmood Talib Hussain | 2019 | Journal of Pharmaceutical Analysis2019，9，1： | 3 |
