| 2 | The development of MOFs-based nanomaterials in heterogeneous organocatalysis显示文摘Metal-organic framework(MOF) is a class of inorganic-organic hybrid material assembled periodically with metal ions and organic ligands. MOFs have always been the focuses in a variety of frontier fields owing to the advantageous properties, such as large BET surface areas, tunable porosity and easyfunctionalized surface structure. Among the various application areas, catalysis is one of the earliest application fields of MOFs-based materials and is one of the fastest-growing topics. In this review, the main roles of MOFs in heterogeneous organocatalysis have been systematically summarized, including used as support materials(or hosts), independent catalysts, and sacrificial templates. Moreover, the application prospects of MOFs in photocatalysis and electrocatalysis frontiers were also mentioned.Finally, the key issues that should be conquered in future were briefly sketched in the final parts of each item. We hope our perspectives could be beneficial for the readers to better understand these topics and issues, and could also provide a direction for the future exploration of some novel types of MOFs-based nanocatalysts with stable structures and functions for heterogeneous catalysis. | Xiaomei Liu Bing Tang Jilan Long Wei Zhang Xiaohong Liu Zakaria Mirza | 2018 | Science Bulletin2018，63，8： | 10 |
| 3 | Lipid droplets and mitochondria are anchored during brown adipocyte differentiation显示文摘Dear Editor,Brown adipose tissue(BAT)acts as a site of non-shivering thermogenesis in mammals including adult humans(Ned-ergaard and Cannon,2010).Prolonged cold exposure can induce the acquisition of thermogenic function in white adipose tissue(WAT)with the cells that have undergone the'browning'process being referred to as beige cells(Wu et al.,2013).Both mainly use mitochondrial p-oxidation of fatty arid(FA)from lipid drnplotc(I He)in maintaining hnHy temperature.The efficiency of hydrophobic FA transport between two organelles in aqueous cytoplasm has been challenged.Understanding the mechanism underlying the interaction between these two organelles is essential for animal physiology as well as for the development of therapies to treat metabolic diseases(Benador et al.,2018). | Liujuan Cui Mirza Ahmed Hammad Shuyan Zhang Bin Liang Pingsheng Liu | 2019 | Protein & Cell2019，10，12： | 8 |

| 5 | Human neural stem cell transplants to address multiple pathologies associated with traumatic brain injury显示文摘Traumatic brain injury (TBI), an unmet need: TBI is an alteration in brain function caused by an external force with evidence of brain pathology. It could be from a bump, blow, blast or jolt to the head including penetrating the cranium. TBI is a public health concern worldwide due to its economic impact. Most TBIs are survivable, do not need hospitalization but may influence productivity. A smaller percentage of TBI due to falls or penetrating TBI (PTBI) needs hospitalization and accounts for largest fraction of TBI care costs. | Helene Clervius Mirza Baig Anil Mahavadi Shyam Gajavelli | 2019 | Neural Regeneration Research2019，14，10： | 7 |
| 6 | Systematic review of oncological outcomes following laparoscopic vs open total mesorectal excision显示文摘AIM: To systematically analyze the randomized trials comparing the oncological and clinical effectiveness of laparoscopic total mesorectal excision(LTME) vs open total mesorectal excision(OTME) in the management of rectal cancer.METHODS: Published randomized, controlled trials comparing the oncological and clinical effectiveness of LTME vs OTME in the management of rectal cancer were retrieved from the standard electronic medical databases. The data of included randomized, controlled trials was extracted and then analyzed according to the principles of meta-analysis using RevMan? statistical software. The combined outcome of the binary variables was expressed as odds ratio(OR) and the combined outcome of the continuous variables waspresented in the form of standardized mean difference(SMD). RESULTS: Data from eleven randomized, controlled trials on 2143 patients were retrieved from the electronic databases. There was a trend towards the higher risk of surgical site infection(OR = 0.66; 95%CI: 0.44-1.00; z = 1.94; P < 0.05), higher risk of incomplete total mesorectal resection(OR = 0.62; 95%CI: 0.43-0.91; z = 2.49; P < 0.01) and prolonged length of hospital stay(SMD,-1.59; 95%CI:-0.86--0.25; z = 4.22; P < 0.00001) following OTME. However, the oncological outcomes like number of harvested lymph nodes, tumour recurrence and risk of positive resection margins were statistically similar in both groups. In addition, the clinical outcomes such as operative complications, anastomotic leak and all-cause mortality were comparable between both approaches of mesorectal excision.CONCLUSION: LTME appears to have clinically and oncologically measurable advantages over OTME in patients with primary rectal cancer in both short term and long term follow ups. | Muhammad Shafique Sajid Adil Ahamd William FA Miles Mirza Khurrum Baig | 2014 | World Journal of Gastrointestinal Endoscopy2014，6，5： | 7 |
| 7 | Structural elucidation of SARS-CoV-2 vital proteins: Computational methods reveal potential drug candidates against main protease, Nsp12 polymerase and Nsp13 helicase显示文摘Recently emerged SARS-CoV-2 caused a major outbreak of coronavirus disease 2019(COVID-19)and instigated a widespread fear,threatening global health safety.To date,no licensed antiviral drugs or vaccines are available against COVID-19 although several clinical trials are under way to test possible therapies.During this urgent situation,computational drug discovery methods provide an alternative to tiresome high-throughput screening,particularly in the hit-to-lead-optimization stage.Identification of small molecules that specifically target viral replication apparatus has indicated the highest potential towards antiviral drug discovery.In this work,we present potential compounds that specifically target SARS-CoV-2 vital proteins,including the main protease,Nsp12 RNA polymerase and Nsp13 helicase.An integrative virtual screening and molecular dynamics simulations approach has facilitated the identification of potential binding modes and favourable molecular interaction profile of corresponding compounds.Moreover,the identification of structurally important binding site residues in conserved motifs located inside the active site highlights relative importance of ligand binding based on residual energy decomposition analysis.Although the current study lacks experimental validation,the structural information obtained from this computational study has paved way for the design of targeted inhibitors to combat COVID-19 outbreak. | Muhammad Usman Mirza Matheus Froeyen | 2020 | Journal of Pharmaceutical Analysis2020，10，4： | 7 |
| 8 | Liver transplantation for alcoholic liver disease显示文摘Alcoholic liver disease(ALD) is the second commonest indication for liver transplantation after viral hepatitis in the United States and Europe.Controversies surround the indications and allocation of scarce and expensive resource for this so called self inflicted disease.Controversies stem from the apprehension that alcoholic recipients are likely to relapse and cause damage to the graft.There is a need to select those candidates with lower risk for relapse with the available predictive factors and scores.Substance abuse specialist and psychiatrists are mandatory in the pre-transplant evaluation and in the post-transplant follow-up.There is conflicting evidence to support a fixed period of pretransplant abstinence,although most units do follow this.Alcoholic hepatitis(AH) continues to be a contraindication for transplantation,however there is a need for further research in this f ield as a subset of patients with AH who do not respond to medical treatment,have high early mortality and could benefit from transplantation.One year,3-year,and 5-year survival post-transplant is similar for both ALD and non-ALD recipients.The incidence of post-transplant rejection and retransplantation is also similar to other recipients.ALD with viral hepatitis especially hepatitis C virus leads to a more aggressive liver disease with early presentation for transplantation.ALD patients are more prone to develop de-novo malignancy;this is attributed to the long term effect of alcohol,tobacco combined with immunosuppression.Post-transplant surveillance is important to detect early relapse to alcoholism,presence of de-novo malignancy and treat the same adequately. | Vibha Varma Kerry Webb Darius F Mirza | 2010 | World Journal of Gastroenterology2010，16，35： | 6 |
| 9 | The Role of Synapsins in Neurological Disorders显示文摘Synapsins serve as flagships among the presynaptic proteins due to their abundance on synaptic vesicles and contribution to synaptic communication. Several studies have emphasized the importance of this multi-gene family of neuron-specific phosphoproteins in maintaining brain physiology. In the recent times, increasing evidence has established the relevance of alterations in synapsins as a major determinant in many neurological disorders. Here,we give a comprehensive description of the diverse roles of the synapsin family and the underlying molecular mechanisms that contribute to several neurological disorders.These physiologically important roles of synapsins associated with neurological disorders are just beginning to be understood. A detailed understanding of the diversified expression of synapsins may serve to strategize novel therapeutic approaches for these debilitating neurological disorders. | Fatima Javed Mirza Saadia Zahid | 2018 | Neuroscience Bulletin2018，34，2： | 6 |

| 13 | Use of health-related quality of life tools in hepatobiliary surgery显示文摘BACKGROUND:The objective of this article is to review the literature and discuss the various tools used in hepatobiliary surgery for the measurement of health related quality of life (HR-QOL) and highlight various outcome variables that affect the HR-QOL among patients with common hepatobiliary disorders. DATA SOURCES: We reviewed HR-QOL articles published in the last 20 years on different hepatobiliary curative or palliative procedures in all languages. RESULTS: HR-QOL is a questionnaire tool which is utilized to assess the changes in the health status of patients after a hepatobiliary intervention. These surveys are of increasingly importance, as health care providers are challenged to justify treatment approaches and rationale for any surgical intervention. These HR-QOL tools are very helpful for the evaluation of subjective outcome of common hepatobiliary procedures like gastrointestinal quality of life index (GIQLI) for cholecystectomy, functional assessment in cancer therapy (FACT) for liver resection, short form 36 (SF-36) for liver transplantation, and quality of life questionnaire for patients with pancreatic cancer (QLQ-PAN). CONCLUSIONS: Use of validated and reliable health instruments in hepatobiliary surgery is directed at measuring the impact in a reproducible and valid fashion. Curative or palliative procedures should be offered to the patients of hepatobiliary disorders after the assessment by HR-QOL tools. Because the impairments of function that may occur after different operations vary considerably, an operation-specific assessment of HR-QOL for each type of surgical procedure is becoming an essential principle to follow in a successful healthcare system. | Muhammad Shafique Sajid Mawara Iftikhar Jasmin Rimple Mirza Khurrum Baig | 2008 | Hepatobiliary & Pancreatic Diseases International2008，7，2： | 5 |

| 15 | Mechanisms of autophagy activation in endothelial cell and their targeting during normothermic machine liver perfusion显示文摘Ischaemia-reperfusion injury(IRI) is the leading cause of injury seen in the liver following transplantation. IRI also causes injury following liver surgery and haemodynamic shock. The first cells within the liver to be injured by IRI are the liver sinusoidal endothelial cells(LSEC). Recent evidence suggests that LSEC coordinate and regulates the livers response to a variety of injuries. It is becoming increasingly apparent that the cyto-protective cellular process of autophagy is a key regulator of IRI. In particular LSEC autophagy may be an essential gatekeeper to the development of IRI. The recent availability of liver perfusion devices has allowed for the therapeutic targeting of autophagy to reduce IRI. In particular normothermic machine liver perfusion(NMP-L) allow the delivery of pharmacological agents to donor livers whilst maintaining physiological temperature and hepatic flow rates. In this review we summarise the current understanding of endothelial autophagy and how this may be manipulated during NMP-L to reduce liver IRI. | Yuri L Boteon Richard Laing Hynek Mergental Gary M Reynolds Darius F Mirza Simon C Afford Ricky H Bhogal | 2017 | World Journal of Gastroenterology2017，23，48： | 4 |
| 16 | Trichoderma-Induced Improvement in Growth, Photosynthetic Pigments, Proline, and Glutathione Levels in Cucurbita pepo Seedlings under Salt Stress显示文摘Salt stress is one of the major abiotic stress in plants.However,traditional approaches are not always efficient in conferring salt tolerance.Experiments were conducted to understand the role of Trichoderma spp.(T.harzianum and T.viride)in growth,chlorophyll(Chl)synthesis,and proline accumulation of C.pepo exposed to salinity stress.There were three salt stress(50,100,and 150 mM NaCl)lavels and three different Trichoderma inoculation viz.T.harzianum,T.viride,and T.harzianum+T.viride.Salt stress significantly declined the growth in terms of the shoot and root lengths;however,it was improved by the inoculation of Trichoderma spp.C.pepo inoculated with Trichoderma exhibited increased synthesis of pigments like chl a,chl b,carotenoids,and anthocyanins under normal conditions.It was interesting to observe that such positive effects were maintained under salt-stressed conditions,as reflected by the amelioration of the salinity-mediated decline in growth,physiology and antioxidant defense.The inoculation of Trichoderma spp.enhanced the synthesis of proline,glutathione,proteins and increased the relative water content.In addition,Trichoderma inoculation increased membrane stability and reduced the generation of hydrogen peroxide.Therefore,Trichoderma spp.can be exploited either individually or in combination to enhance the growth and physiology of C.pepo under saline conditions. | Mona H.Soliman Taghreed S.Alnusaire Nessreen FAbdelbaky Aisha A.M.Alayafi Mirza Hasanuzzaman Mohamed M.Rowezak Mohamed El-Esawi Amr Elkelish | 2020 | Phyton-International Journal of Experimental Botany2020，89，3： | 4 |
| 17 | Robotic total meso-rectal excision for rectal cancer: A systematic review following the publication of the ROLARR trial显示文摘AIM To compare outcomes in patients undergoing rectal resection by robotic total meso-rectal excision(RTME) vs laparoscopic total meso-rectal excision(LTME).METHODS Standard medical electronic databases such as Pub-Med, MEDLINE, EMBASE and Scopus were searched to find relevant articles. The data retrieved from all types of included published comparative trials in pati-ents undergoing RTME vs LTME was analysed using the principles of meta-analysis. The operative, post-operative and oncological outcomes were evaluated to assess the effectiveness of both techniques of TME. The summated outcome of continuous variables was expressed as standardized mean difference(SMD) and dichotomous data was presented in odds ratio(OR).RESULTS One RCT(ROLARR trial) and 27 other comparative studies reporting the non-oncological and oncological outcomes following RTME vs LTME were included in this review. In the random effects model analysis using the statistical software Review Manager 5.3, the RTME was associated with longer operation time(SMD, 0.46; 95%CI: 0.25, 0.67; z = 4.33; P = 0.0001), early passage of first flatus(P = 0.002), lower risk of conversion(P = 0.00001) and shorter hospitalization(P = 0.01). The statistical equivalence was seen between RTME and LTME for non-oncological variables like blo-od loss, morbidity, mortality and re-operation risk. The oncological variables such as recurrence(P = 0.96), number of harvested nodes(P = 0.49) and positive circumferential resection margin risk(P = 0.53) were also comparable in both groups. The length of distal resection margins was similar in both groups. CONCLUSION RTME is feasible and oncologically safe but failed to demonstrate any superiority over LTME for many sur-gical outcomes except early passage of flatus, lower risk of conversion and shorter hospitalization. | Katie Jones Mohamed G Qassem Parv Sains Mirza K Baig Muhammad S Sajid | 2018 | World Journal of Gastrointestinal Oncology2018，10，11： | 4 |
| 18 | 反相高效液相色谱法同时测定片剂中的加替沙星与盐酸氨溴索(英文)显示文摘A reversed-phase high performance liquid chromatography (HPLC) method was developed, validated, and used for the quantitative determination of gatifloxacin (GA) and ambroxol hydrochloride (AM), from its tablet dosage form. Chromatographic separation was performed on a HiQ Sil C18 column (250 mm×4.6 mm, 5 μm), with a mobile phase comprising of a mixture of 0.01 mol/L potassium dihydrogen orthophosphate buffer and acetonitrile (70∶30, v/v), and pH adjusted to 3 with orthophosphoric acid, at a flow rate of 1 mL/min, with detection at 247 nm. Separation was completed in less than 10 min. As per International Conference on Harmonisation (ICH) guidelines the method was validated for linearity, accuracy, precision, limit of quantitation, limit of detection, and robustness. Linearity of GA was found to be in the range of 10-60 μg/mL and that for AM was found to be 5-30 μg/mL. The correlation coefficients were 0.999 6 and 0.999 3 for GA and AM respectively. The results of the tablet analysis (n=5) were found to be 99.94% with ±0.25% standard deviation (SD) and 99.98% with±0.36% SD for GA and AM respectively. Percent recovery of GA was found to be 99.92%-100.02% and that of AM was 99.86%-100.16%. The assay experiment shows that the method is free from interference of excipients. This demonstrates that the developed HPLC method is simple, linear, precise, and accurate, and can be conveniently adopted for the routine quality control analysis of the tablet. | SHAHED Mirza NANDA Rabindra DEHGHAN Muhammad Hassan NASREEN Huda FEROZ Shaikh | 2008 | 色谱2008，26，3： | 3 |
| 19 | Fractional order modeling and control of dissimilar redundant actuating system used in large passenger aircraft显示文摘In this paper, a methodology has been developed to address the issue of force fighting and to achieve precise position tracking of control surface driven by two dissimilar actuators.The nonlinear dynamics of both actuators are first approximated as fractional order models. Based on the identified models, three fractional order controllers are proposed for the whole system. Two Fractional Order PID(FOPID) controllers are dedicated to improving transient response and are designed in a position feedback configuration. In order to synchronize the actuator dynamics, a third fractional order PI controller is designed, which feeds the force compensation signal in position feedback loop of both actuators. Nelder-Mead(N-M) optimization technique is employed in order to optimally tune controller parameters based on the proposed performance criteria. To test the proposed controllers according to real flight condition, an external disturbance of higher amplitude that acts as airload is applied directly on the control surface. In addition, a disturbance signal function of system states is applied to check the robustness of proposed controller. Simulation results on nonlinear system model validated the performance of the proposed scheme as compared to optimal PID and high gain PID controllers. | Salman IJAZ Lin YAN Mirza Tariq HAMAYUN | 2018 | Chinese Journal of Aeronautics2018，31，5： | 3 |
| 20 | Exogenous Selenium Mitigates Salt Stress in Soybean by Improving Growth,Physiology,Glutathione Homeostasis and Antioxidant Defense显示文摘The mechanism of selenium(Se)-induced salt tolerance was studied in moderately sensitive soybean(Glycine max L.)plants.To execute this view,soybean plants were imposed with salt stress(EC 6 dS m^(−1))applying NaCl.In other treatments,Se(0,25,50 and 75μM Na_(2)SeO_(4))was sprayed as co-application with that level of salt stress.Plant height,stem diameter,leaf area,SPAD value decreased noticeably under salt stress.Altered proline(Pro)level,together with decreased leaf relative water content(RWC)was observed in salt-affected plants.Salt stress resulted in brutal oxidative damage and increased the content of H_(2)O_(2),MDA level and electrolyte leakage.Exogenous Se spray alleviated oxidative damage through boosting up the antioxidant defense system by increasing the activity of antioxidant enzymes such as catalase(CAT),peroxidase(POD)and glutathione reductase(GR),as well as by improving non-enzymatic antioxidants like glutathione(GSH)and GSH/glutathione disulfide(GSSG).The upregulated antioxidant defense system,restored Pro and leaf RWC,higher SPAD value conferred better growth and development in Se-sprayed salt-affected soybean plants which altogether put forth for the progressive yield contributing parameters and finally,seed yield.Among different doses of Se,soybean plants sprayed with 50μM Na_(2)SeO_(4)showed better salt tolerance. | Hesham F.Alharby Mirza Hasanuzzaman Hassan S.Al-Zahrani Khalid Rehman Hakeem | 2021 | Phyton-International Journal of Experimental Botany2021，90，2： | 3 |
