1Hepatitis B and C virus-induced hepatitis: Apoptosis, autophagy, and unfolded protein response显示文摘AIM: To investigate the co-incidence of apoptosis, autophagy, and unfolded protein response(UPR) in hepatitis B(HBV) and C(HCV) infected hepatocytes.METHODS: We performed immunofluorescence confocal microscopy on 10 liver biopsies from HBV and HCV patients and tissue microarrays of HBV positive liver samples. We used specific antibodies for LC3β, cleaved caspase-3, BIP(GRP78), and XBP1 to detect autophagy, apoptosis and UPR, respectively. AntiHCV NS3 and anti-HBs antibodies were also used to confirm infection. We performed triple blind counting of events to determine the co-incidence of autophagy(LC3β punctuate), apoptosis(cleaved caspase-3), and unfolded protein response(GRP78) with HBV and HCV infection in hepatocytes. All statistical analyses were performed using SPSS software for Windows(Version 16 SPSS Inc, Chicago, IL, United States). P-values < 0.05 were considered statistically significant. Statistical analyses were performed with Mann-Whitney test to compare incidence rates for autophagy, apoptosis, and UPR in HBV- and HCV-infected cells and adjacent noninfected cells.RESULTS: Our results showed that infection of hepatocytes with either HBV and HCV induces significant increase(P < 0.001) in apoptosis(cleavage of caspase-3), autophagy(LC3β punctate), and UPR(increase in GRP78 expression) in the HCV- and HBVinfected cells, as compared to non-infected cells of the same biopsy sections. Our tissue microarray immunohistochemical expression analysis of LC3β in HBV^(Neg) and HBV^(Pos) revealed that majority of HBVinfected hepatocytes display strong positive stainingfor LC3β. Interestingly, although XBP splicing in HBVinfected cells was significantly higher(P < 0.05), our analyses show a slight increase of XBP splicing was in HCV-infected cells(P > 0.05). Furthermore, our evaluation of patients with HBV and HCV infection based on stage and grade of the liver diseases revealed no correlation between these pathological findings and induction of apoptosis, autophagy, and UPR.CONCLUSION: The results of this study indicate that HCV and HBV infection activates apoptosis, autophagy and UPR, but slightly differently by each virus. Further studies are warranted to elucidate the interconnections between these pathways in relation to pathology of HCV and HBV in the liver tissue.Behzad Yeganeh Adel Rezaei Moghadam Javad Alizadeh Emilia Wiechec Seyed Moayed Alavian Mohammad Hashemi Bita Geramizadeh Afshin Samali Kamran Bagheri Lankarani Martin Post Payam Peymani Kevin M Coombs Saeid Ghavami 2015World Journal of Gastroenterology2015,21,47:13

3Predictive value and main determinants of abnormal features of intraoperative cholangiography during cholecystectomy显示文摘BACKGROUND:The major issue with intraoperative cholangiography (IOC) is whether its diagnostic accuracy for common bile duct (CBD) stones matches that of other diagnostic procedures,and thus,whether it will become a routine diagnostic procedure.The current study aimed to address the main determinants of CBD stone diagnosis in IOC among an Iranian population.METHODS:In a retrospective review database-based study conducted in Taleghani Hospital in Tehran between 2006 and 2008,baseline data and perioperative information of 2060 patients (male to female ratio 542:1518,mean age 53.7 years) who were candidates for cholecystectomy and underwent concomitant IOC for confirming CBD stones were reviewed.The predictive power of this procedure for diagnosis of abnormal biliary ducts with the focus on biliary stones was determined.RESULTS:Overall mortality and morbidity following cholecystectomy in the study population were 0.6% and 2.6%,respectively.Both early mortality and morbidity due to cholecystectomy were higher in male than female.The prevalence of CBD stones in IOC was 3.4% (5.2% in male and 2.8% in female,P=0.008).Among those without gallstones,8.7% had CBD stones and only 3.1% had concomitant gallstones and CBD stones.The main predictors of stone appearance as an abnormal feature of IOC during cholecystectomy were:advanced age (OR=1.022,P=0.001),male gender (OR=1.498,P=0.050),history of abdominal surgery (OR=1.543,P=0.040) and preoperative endoscopic retrograde cholangiopancreatography (OR=5.400,P<0.001).CONCLUSIONS:IOC is a safe and accurate method for the assessment of bile duct anatomy and stones.Therefore,the routine use of IOC within cholecystectomy seems reasonable and is recommended.Shahram Yousefpour Azary Heshmat Kalbasi Ali Setayesh Mirhadi Mousavi Asad Hashemi Mahsa Khodadoostan Mohammad Reza Zali Amir Houshang Mohammad Alizadeh 2011Hepatobiliary & Pancreatic Diseases International2011,10,3:11
4TIRAP rs8177374 gene polymorphism increased the risk of pulmonary tuberculosis in Zahedan,southeast Iran显示文摘Objective:To evaluate the possible association between Toll-interleukin 1 receptor(TIR) domain containing adaptor protein(TIRAP;also known as MAI.) rsl893352 and rs8l77374(S180L) gene polymorphisms and pulmonary tuberculosis(PTB) in a sample of Iranian population.Methods:This case-control study was performed on 174 PTB and 177 healthy subjects.Tetra amplification refractory mutation systetn-polymerase chain reaction(T-AKMS-PCR) was used to detect the polymorphisms.Results:Our finding showed that neither the overall Ckisqaare comparison of PTB and control subjects nor the logistic regression analysis indicated any association between rsl893352 polymorphism and PTB.Regarding rs8l77374 polymorphism,the CT genotype as well as CT+TT increased the risk of PTB in comparison with CC genotype(OR=4.73,95%CI=2.65-8.45,P<0.0001 and OR=6.47,95%C1=3.68-11.38,P<0.0001.respectively).The rs8177374 T allele increased the risk of PTB in comparison with C allele(OR=4.21.95%CI=2.43-7.26,P<0.0001).Conclusions:Our finding indicates that TIRAP rs8177374 polymorphism is associated with PTB in a sample of Iranian population.Mohammad Naderi Mohammad Hashemi Zahra Pourmontaseri Ebrahim Eskari-Nasab Gholamreza Bahari Mohsen Taheri 2014Asian Pacific Journal of Tropical Medicine2014,7,6:8

7Synthesis and antibacterial activity of Schiff bases of 5-substituted isatins显示文摘Based on the existing reports on the bioactive isatin derivatives, a number of Schiff bases were synthesized by reacting 5-substituted isatins with bioactive amines/hydrazides and their structures were confirmed using spectroscopic methods such as NMR, IR and mass spectrometry. Furthermore, Nbenzylation of isatin followed by the Schiff base formation furnished a new series of compounds(11a–13c) which allowed the analysis of the effect of isatin N-substitution on the bioactivity of the resulting compounds. The antibacterial activity of the synthesized derivatives was evaluated using a microtiter plate method on a series of gram positive and gram negative bacterial strains. Compounds 2d, 3b, 5c and 6a were among the most potent derivatives against Pseudomonas aeruginosa(MIC = 6.25 μg/m L).Analysis of the structure–activity relationship showed that the incorporation of(thio)urea-based Schiff bases lead to more potent derivatives with a broader spectrum of antibacterial activity. In addition,highly lipophilic compounds such as 11a–12c did not show any measurable antibacterial activity, which implies that an optimal lipophilicity might be an important requirement for the antibacterial activity of the studied isatins. Finally, the finding that hydantoin derivatives of N-benzylisatins(13a–13c) still exhibit some antibacterial activity prompted us to consider exploring the bioactivity of more diverse derivatives of isatin-aminohydantoin Schiff bases(compounds 1a–1d) in our future studies.Kamaleddin Haj Mohammad Ebrahim Tehrani Maryam Hashemi Maryam Hassan Farzad Kobarfard Shohreh Mohebbi 2016Chinese Chemical Letters2016,27,2:6

10Enhanced oil recovery from carbonate reservoirs by spontaneous imbibition of low salinity water显示文摘An experimental study was performed to investigate the impact of low salinity water on wettability alteration in carbonate core samples from southern Iranian reservoirs by spontaneous imbibition. In this paper, the effect of temperature, salinity,permeability and connate water were investigated by comparing the produced hydrocarbon curves. Contact angle measurements were taken to confirm the alteration of surface wettability of porous media. Oil recovery was enhanced by increasing the dilution ratio of sea water, and there existed an optimum dilution ratio at which the highest oil recovery was achieved. In addition, temperature had a very significant impact on oil recovery from carbonate rocks. Furthermore, oil recovery from a spontaneous imbibition process was directly proportional to the permeability of the core samples. The presence of connate water saturation inside the porous media facilitated oil production significantly. Also, the oil recovery from porous media was highly dependent on ion repulsion/attraction activity of the rock surface which directly impacts on the wettability conditions. Finally, the highest ion attraction percentage was measured for sodium while there was no significant change in pH for all experiments.Mohammad Reza Zaeri Rohallah Hashemi Hamidreza Shahverdi Mehdi Sadeghi 2018Petroleum Science2018,15,3:2
11Review of recycling waste plastics in asphalt paving materials显示文摘An ever-growing demand for depleted natural resources is one of the significant challenges facing the global asphalt pavement industry in building and maintaining global asphalt pavements.Because plastics are ubiquitous in the global economy,they are the latest in a series of high-profile materials to attract attention.Their low material recovery rates and the environmental impact of current disposal methods pose a threat to plastic recycling.Recycling plastic wastes in asphalt pavement is a possible approach to reducing environmental pressure and the demand for depleted natural resources.Many studies have proposed recycling plastic waste in asphalt pavement using dry-and wet-processed technologies.This review aims to comprehensively evaluate the feasibility of various recycled plastics in asphalt pavement concerning the properties of compatibility,storage stability,microstructure,thermo-rheology,and mechanical performance and to identify hallenges and recommendations for the future.This review discusses recent developments and the feasibility of using plastic wastes as modifiers or additives to asphalt binders or asphalt mixtures in dry and wet processes,focusing on different materials from waste streams,how to produce such modified materials,and the characteristics of plastic waste modified asphalt,thus contributing to the sustainable management of resources and production of useful paving materials.Lingyun You Zhengwu Long Zhanping You Dongdong Ge Xu Yang Fu Xu Mohammad Hashemi Aboelkasim Diab 2022Journal of Traffic and Transportation Engineering(English Edition)2022,9,5:2

13Digital spiral object identification using random light显示文摘Photons that are entangled or correlated in orbital angular momentum have been extensively used for remote sensing,object identification and imaging.It has recently been demonstrated that intensity fluctuations give rise to the formation of correlations in the orbital angular momentum components and angular positions of random light.Here we demonstrate that the spatial signatures and phase information of an object with rotational symmetries can be identified using classical orbital angular momentum correlations in random light.The Fourier components imprinted in the digital spiral spectrum of the object,as measured through intensity correlations,unveil its spatial and phase information.Sharing similarities with conventional compressive sensing protocols that exploit sparsity to reduce the number of measurements required to reconstruct a signal,our technique allows sensing of an object with fewer measurements than other schemes that use pixel-by-pixel imaging.One remarkable advantage of our technique is that it does not require the preparation of fragile quantum states of light and operates at both low-and high-light levels.In addition,our technique is robust against environmental noise,a fundamental feature of any realistic scheme for remote sensing.Zhe Yang Omar S Magaña-Loaiza Mohammad Mirhosseini Yiyu Zhou Boshen Gao Lu Gao Seyed Mohammad Hashemi Rafsanjani Gui-Lu Long Robert W Boyd 2017Light(Science & Applications)2017,6,1:2

15A GIS-based time-dependent seismic source modeling of Northern Iran显示文摘The first step in any seismic hazard study is the definition of seismogenic sources and the estimation of magnitude-frequency relationships for each source.There is as yet no standard methodology for source modeling and many researchers have worked on this topic.This study is an effort to define linear and area seismic sources for Northern Iran.The linear or fault sources are developed based on tectonic features and characteristic earthquakes while the area sources are developed based on spatial distribution of small to moderate earthquakes.Time-dependent recurrence relationships are developed for fault sources using renewal approach while time-independent frequency-magnitude relationships are proposed for area sources based on Poisson process.GIS functionalities are used in this study to introduce and incorporate spatialtemporal and geostatistical indices in delineating area seismic sources.The proposed methodology is used to model seismic sources for an area of about 500 by 400 square kilometers around Tehran.Previous researches and reports are studied to compile an earthquake/fault catalog that is as complete as possible.All events are transformed to uniform magnitude scale; duplicate events and dependent shocks are removed.Completeness and time distribution of the compiled catalog is taken into account.The proposed area and linear seismic sources in conjunction with defined recurrence relationships can be used to develop time-dependent probabilistic seismic hazard analysis of Northern Iran.Mahdi Hashemi Ali Asghar Alesheikh Mohammad Reza Zolfaghari 2017Earthquake Engineering and Engineering Vibration2017,16,1:1

18Toll-like Receptor 1 Polymorphisms Increased the Risk of Pulmonary Tuberculosis in an Iranian Population Sample显示文摘A case-control study was carried out that involved 203 individuals diagnosed with pulmonary tuberculosis (PTB) and 203 healthy subjects. Genotyping of TLR1 rs5743551 and rs5743618 polymorphisms was done using polymerase chain reaction-restriction fragments length polymorphism assay. We found that TLR1 rs5743551 variant affected the risk of PTB in the codominant (OR=3.28, 95% CI=1.98-5.45, P<0.0001, GA vs. GG; OR=1.86, 95% CI=1.05-3.28, P=0.033, AA vs. GG) and dominant (OR=2.69, 95% CI=1.67-4.34, P<0.0001, GA+AA vs. GG) inheritance models tested. The A allele was associated with a higher risk of PTB than the G allele (OR=1.33, 95% CI=1.01-1.75, P=0.049). The TG genotype of the rs5743618 variant significantly increased the risk of PTB compared to the risk associated with the TT genotype (OR=3.29, 95% CI=1.82-5.97, P<0.0001). The G allele was associated with a higher risk of PTB than the T allele (OR=3.00, 95% CI=1.69-5.31, P=0.0001). Our findings revealed that TLR1 rs5743551 and rs5743618 polymorphisms affected the risk of PTB in an Iranian population sample. Additional studies with larger sample sizes and involving subjects of different ethnicities are required to validate our present findings.Mohammad Naderi Mohammad Hashemi Hamideh Mirshekari Gholamreza Bahari Mohsen Taheri 2016Biomedical and Environmental Sciences2016,29,11:1
