Agarose (a natural polymer) have been used largely for angiogenesis, cartilage formation and wound healing applications. However, electrospinning of agarose is tedious thereby rendering limited studies on fabrication and evaluation of agarose based nanofibrous wound dressings. Thus, present study focuses on the fabrication of agarose (10% w/v)/ polyvinyl alcohol (12% w/v) based multifunctional nanofibrous scaffolds. Zinc citrate (1, 3 and 5% w/w of the polymer) was added as a potential antibacterial agent to combat wound infections. The fabricated scaffolds exhibit ~500% swelling (in phosphate buffer saline) with enhanced mechanical strength which is suitable for most of the wound healing applications. In vitro studies were found to reveal an increased migration and proliferation of L929 mouse fibroblasts with agarose blends w.r.t to the control. The fabricated dressings were found to be effective against both Escherichia coli (Gram-negative) and Staphylococcus aureus (Gram-positive) bacterial strains. Hence, a multifunctional (as provides effective swelling and mechanical support along with antibacterial property), natural product based, eco-friendly scaffold was successfully fabricated to serve as a potential wound dressing material. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antibacterial%20dressings" title="antibacterial dressings">antibacterial dressings</a>, <a href="https://publications.waset.org/abstracts/search?q=benign%20solvent" title=" benign solvent"> benign solvent</a>, <a href="https://publications.waset.org/abstracts/search?q=nanofibrous%20agarose" title=" nanofibrous agarose"> nanofibrous agarose</a>, <a href="https://publications.waset.org/abstracts/search?q=biocompatibility" title=" biocompatibility"> biocompatibility</a>, <a href="https://publications.waset.org/abstracts/search?q=enhanced%20swelling%20and%20mechanical%20strength" title=" enhanced swelling and mechanical strength"> enhanced swelling and mechanical strength</a>, <a href="https://publications.waset.org/abstracts/search?q=biopolymeric%20dressings" title=" biopolymeric dressings"> biopolymeric dressings</a> </p> <a href="https://publications.waset.org/abstracts/152755/agarose-based-multifunctional-nanofibrous-bandages-for-wound-healing-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152755.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">93</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">50</span> Optimization of a Method of Total RNA Extraction from Mentha piperita</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Soheila%20Afkar">Soheila Afkar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mentha piperita is a medicinal plant that contains a large amount of secondary metabolite that has adverse effect on RNA extraction. Since high quality of RNA is the first step to real time-PCR, in this study optimization of total RNA isolation from leaf tissues of Mentha piperita was evaluated. From this point of view, we researched two different total RNA extraction methods on leaves of Mentha piperita to find the best one that contributes the high quality. The methods tested are RNX-plus, modified RNX-plus (1-5 numbers). RNA quality was analyzed by agarose gel 1.5%. The RNA integrity was also assessed by visualization of ribosomal RNA bands on 1.5% agarose gels. In the modified RNX-plus method (number 2), the integrity of 28S and 18S rRNA was highly satisfactory when analyzed in agarose denaturing gel, so this method is suitable for RNA isolation from Mentha piperita. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mentha%20piperita" title="Mentha piperita">Mentha piperita</a>, <a href="https://publications.waset.org/abstracts/search?q=polyphenol" title=" polyphenol"> polyphenol</a>, <a href="https://publications.waset.org/abstracts/search?q=polysaccharide" title=" polysaccharide"> polysaccharide</a>, <a href="https://publications.waset.org/abstracts/search?q=RNA%20extraction" title=" RNA extraction"> RNA extraction</a> </p> <a href="https://publications.waset.org/abstracts/95845/optimization-of-a-method-of-total-rna-extraction-from-mentha-piperita" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95845.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">190</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">49</span> Land Subsidence Monitoring in Semarang and Demak Coastal Area Using Persistent Scatterer Interferometric Synthetic Aperture Radar</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Reyhan%20Azeriansyah">Reyhan Azeriansyah</a>, <a href="https://publications.waset.org/abstracts/search?q=Yudo%20Prasetyo"> Yudo Prasetyo</a>, <a href="https://publications.waset.org/abstracts/search?q=Bambang%20Darmo%20Yuwono"> Bambang Darmo Yuwono</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Land subsidence is one of the problems that occur in the coastal areas of Java Island, one of which is the Semarang and Demak areas located in the northern region of Central Java. The impact of sea erosion, rising sea levels, soil structure vulnerable and economic development activities led to both these areas often occurs on land subsidence. To know how much land subsidence that occurred in the region needs to do the monitoring carried out by remote sensing methods such as PS-InSAR method. PS-InSAR is a remote sensing technique that is the development of the DInSAR method that can monitor the movement of the ground surface that allows users to perform regular measurements and monitoring of fixed objects on the surface of the earth. PS InSAR processing is done using Standford Method of Persistent Scatterers (StaMPS). Same as the recent analysis technique, Persistent Scatterer (PS) InSAR addresses both the decorrelation and atmospheric problems of conventional InSAR. StaMPS identify and extract the deformation signal even in the absence of bright scatterers. StaMPS is also applicable in areas undergoing non-steady deformation, with no prior knowledge of the variations in deformation rate. In addition, this method can also cover a large area so that the decline in the face of the land can cover all coastal areas of Semarang and Demak. From the PS-InSAR method can be known the impact on the existing area in Semarang and Demak region per year. The PS-InSAR results will also be compared with the GPS monitoring data to determine the difference in land decline that occurs between the two methods. By utilizing remote sensing methods such as PS-InSAR method, it is hoped that the PS-InSAR method can be utilized in monitoring the land subsidence and can assist other survey methods such as GPS surveys and the results can be used in policy determination in the affected coastal areas of Semarang and Demak. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=coastal%20area" title="coastal area">coastal area</a>, <a href="https://publications.waset.org/abstracts/search?q=Demak" title=" Demak"> Demak</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20subsidence" title=" land subsidence"> land subsidence</a>, <a href="https://publications.waset.org/abstracts/search?q=PS-InSAR" title=" PS-InSAR"> PS-InSAR</a>, <a href="https://publications.waset.org/abstracts/search?q=Semarang" title=" Semarang"> Semarang</a>, <a href="https://publications.waset.org/abstracts/search?q=StaMPS" title=" StaMPS"> StaMPS</a> </p> <a href="https://publications.waset.org/abstracts/88688/land-subsidence-monitoring-in-semarang-and-demak-coastal-area-using-persistent-scatterer-interferometric-synthetic-aperture-radar" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88688.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">266</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">48</span> Agarose Amplification Based Sequencing (AG-seq) Characterization Cell-free RNA in Preimplantation Spent Embryo Medium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huajuan%20Shi">Huajuan Shi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: The biopsy of the preimplantation embryo may increase the potential risk and concern of embryo viability.

Unfortunately, it always fails to unwrap the phase for two reasons: 1) spatial phase jump between adjacent pixels larger than π, such as layover and high discontinuous terrain; 2) temporal phase discontinuities such as time varied atmospheric delay. To overcome these limitations, a least-square based PU method is introduced in this paper, which incorporates baseline-combination interferograms and adjacent phase gradient network. Firstly, permanent scatterers (PS) are selected for study. Starting with the linear baseline-combination method, we obtain equivalent 'small baseline inteferograms' to limit the spatial phase difference. Then, phase different has been conducted between connected PSs (connected by a specific networking rule) to suppress the spatial correlated phase errors such as atmospheric artifact. After that, interval phase difference along arcs can be computed by least square method and followed by an outlier detector to remove the arcs with phase ambiguities. Then, the unwrapped phase can be obtained by spatial integration. The proposed method is tested on real data of TerraSAR-X, and the results are also compared with the ones obtained by StaMPS(a software package with 3D PU capabilities). By comparison, it shows that the proposed method can successfully unwrap the interferograms in urban areas even when high discontinuities exist, while StaMPS fails. At last, precise DEM errors can be got according to the unwrapped interferograms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=phase%20unwrapping" title="phase unwrapping">phase unwrapping</a>, <a href="https://publications.waset.org/abstracts/search?q=time%20series" title=" time series"> time series</a>, <a href="https://publications.waset.org/abstracts/search?q=InSAR" title=" InSAR"> InSAR</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20areas" title=" urban areas"> urban areas</a> </p> <a href="https://publications.waset.org/abstracts/97800/insar-times-series-phase-unwrapping-for-urban-areas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/97800.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">151</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">44</span> Prediction of Ionizing Radiation Doses in Irradiated red Pepper (Capsicum annuum) and Mint (Mentha piperita) by Gel Electrophoresis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=%C5%9Eeyma%20%C3%96z%C3%A7irak%20Erg%C3%BCn">Şeyma Özçirak Ergün</a>, <a href="https://publications.waset.org/abstracts/search?q=Erg%C3%BCn%20%C5%9Eakalar"> Ergün Şakalar</a>, <a href="https://publications.waset.org/abstracts/search?q=Emrah%20Yalazi%CC%87"> Emrah Yalazi̇</a>, <a href="https://publications.waset.org/abstracts/search?q=Nebahat%20%C5%9Eahi%CC%87n"> Nebahat Şahi̇n</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Food irradiation is a usage of exposing food to ionising radiation (IR) such as gamma rays. IR has been used to decrease the number of harmful microorganisms in the food such as spices. Excessive usage of IR can cause damage to both food and people who consuming food. And also it causes to damages on food DNA. Generally, IR detection techniques were utilized in literature for spices are Electron Spin Resonance (ESR), Thermos Luminescence (TL). Storage creates negative effect on IR detection method then analyses of samples have been performed without storage in general. In the experimental part, red pepper (Capsicum annuum) and mint (Mentha piperita) as spices were exposed to 0, 0.272, 0.497, 1.06, 3.64, 8.82, and 17.42 kGy ionize radiation. ESR was applied to samples irradiated. DNA isolation from irradiated samples was performed using GIDAGEN Multi Fast DNA isolation kit. The DNA concentration was measured using a microplate reader spectrophotometer (Infinite® 200 PRO-Life Science–Tecan). The concentration of each DNA was adjusted to 50 ng/µL. Genomic DNA was imaged by UV transilluminator (Gel Doc XR System, Bio-Rad) for the estimation of genomic DNA bp-fragment size after IR. Thus, agarose gel profiles of irradiated spices were obtained to determine the change of band profiles. Besides, samples were examined at three different time periods (0, 3, 6 months storage) to show the feasibility of developed method. Results of gel electrophoresis showed especially degradation of DNA of irradiated samples. In conclusion, this study with gel electrophoresis can be used as a basis for the identification of the dose of irradiation by looking at degradation profiles at specific amounts of irradiation. Agarose gel results of irradiated samples were confirmed with ESR analysis. This method can be applied widely to not only food products but also all biological materials containing DNA to predict radiation-induced damage of DNA. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DNA" title="DNA">DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=electrophoresis" title=" electrophoresis"> electrophoresis</a>, <a href="https://publications.waset.org/abstracts/search?q=gel%20electrophoresis" title=" gel electrophoresis"> gel electrophoresis</a>, <a href="https://publications.waset.org/abstracts/search?q=ionizeradiation" title=" ionizeradiation"> ionizeradiation</a> </p> <a href="https://publications.waset.org/abstracts/53071/prediction-of-ionizing-radiation-doses-in-irradiated-red-pepper-capsicum-annuum-and-mint-mentha-piperita-by-gel-electrophoresis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/53071.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">259</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">43</span> Immobilization of β-Galactosidase from Kluyveromyces Lactis on Polyethylenimine-Agarose for Production of Lactulose</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Carlos%20A.%20C.%20G.%20Neto">Carlos A.

These enzymes, when immobilized, can have some enzymatic characteristics substantially improved, and the coating of supports with multifunctional polymers in immobilization processes is a promising alternative in order to extend the useful life of the biocatalysts, for example, the coating with polyethyleneimine (PEI). PEI is a flexible polymer that suits the structure of the enzyme, giving greater stability, especially for multimeric enzymes such as β-galactosidases and also protects it from environmental variations, for example, pH and temperature. In addition, it can substantially improve the immobilization parameters and also the efficiency of enzymatic reactions. In this context, the aim of the present work was first to develop biocatalysts of β-galactosidase from Kluyveromyces lactis immobilized on PEI coated agarose, determining the immobilization parameters, its operational and thermal stability, and then to apply it in the hydrolysis of lactose and synthesis of lactulose, using whey as a substrate. This immobilization strategy was chosen in order to improve the catalytic efficiency of the enzyme in the transgalactosylation reaction for the production of prebiotics, and there are few studies with β-galactosidase from this strain. The immobilization of β-galactosidase in agarose previously functionalized with 48% (w/v) glycidol and then coated with 10% (w/v) PEI solution was evaluated using an enzymatic load of 10 mg/g of protein. Subsequently, the hydrolysis and transgalactosylation reactions were conducted at 50 °C, 120 RPM for 20 minutes, using whey (66.7 g/L of lactose) supplemented with 133.3 g/L fructose at a ratio of 1:2 (lactose/fructose). Operational stability studies were performed in the same conditions for 10 cycles. Thermal stabilities of biocatalysts were conducted at 50 ºC in 50 mM phosphate buffer, pH 6.6, with 0.1 mM MnCl2. The biocatalysts whose supports were coated were named AGA_GLY_PEI_GAL, and those that were not coated were named AGA_GLY_GAL. The coating of the support with PEI considerably improved immobilization yield (2.6-fold), the biocatalyst activity (1.4-fold), and efficiency (2.2-fold). The biocatalyst AGA_GLY_PEI_GAL was better than AGA_GLY_GAL in hydrolysis and transgalactosylation reactions, converting 88.92% of lactose at 5 min of reaction and obtaining a residual concentration of 5.24 g/L. Besides that, it was produced 13.90 g/L lactulose in the same time interval. AGA_GLY_PEI_GAL biocatalyst was stable during the 10 cycles evaluated, converting approximately 80% of lactose and producing 10.95 g/L of lactulose even after the tenth cycle. However, the thermal stability of AGA_GLY_GAL biocatalyst was superior, with a half-life time 5 times higher, probably because the enzyme was immobilized by covalent bonding, which is stronger than adsorption (AGA_GLY_PEI_GAL). Therefore, the strategy of coating the supports with PEI has proven to be effective for the immobilization of β-galactosidase from K. lactis, considerably improving the immobilization parameters, as well as the enzyme, catalyzed reactions. In addition, the use of whey as a raw material for lactulose production has proved to be an industrially advantageous alternative. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=%CE%B2-galactosidase" title="β-galactosidase">β-galactosidase</a>, <a href="https://publications.waset.org/abstracts/search?q=immobilization" title=" immobilization"> immobilization</a>, <a href="https://publications.waset.org/abstracts/search?q=lactulose" title=" lactulose"> lactulose</a>, <a href="https://publications.waset.org/abstracts/search?q=polyethylenimine" title=" polyethylenimine"> polyethylenimine</a>, <a href="https://publications.waset.org/abstracts/search?q=whey" title=" whey"> whey</a> </p> <a href="https://publications.waset.org/abstracts/120441/immobilization-of-v-galactosidase-from-kluyveromyces-lactis-on-polyethylenimine-agarose-for-production-of-lactulose" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/120441.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">119</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">42</span> Salmonella Emerging Serotypes in Northwestern Italy: Genetic Characterization by Pulsed-Field Gel Electrophoresis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Clara%20Tramuta">Clara Tramuta</a>, <a href="https://publications.waset.org/abstracts/search?q=Floris%20Irene"> Floris Irene</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniela%20Manila%20Bianchi"> Daniela Manila Bianchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Monica%20Pitti"> Monica Pitti</a>, <a href="https://publications.waset.org/abstracts/search?q=Giulia%20Federica%20Cazzaniga"> Giulia Federica Cazzaniga</a>, <a href="https://publications.waset.org/abstracts/search?q=Lucia%20Decastelli"> Lucia Decastelli</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This work presents the results obtained by the Regional Reference Centre for Salmonella Typing (CeRTiS) in a retrospective study aimed to investigate, through Pulsed-field Gel Electrophoresis (PFGE) analysis, the genetic relatedness of emerging Salmonella serotypes of human origin circulating in North-West of Italy. Furthermore, the goal of this work was to create a Regional database to facilitate foodborne outbreak investigation and to monitor them at an earlier stage. A total of 112 strains, isolated from 2016 to 2018 in hospital laboratories, were included in this study. The isolates were previously identified as Salmonella according to standard microbiological techniques and serotyping was performed according to ISO 6579-3 and the Kaufmann-White scheme using O and H antisera (Statens Serum Institut®). All strains were characterized by PFGE: analysis was conducted according to a standardized PulseNet protocol. The restriction enzyme XbaI was used to generate several distinguishable genomic fragments on the agarose gel. PFGE was performed on a CHEF Mapper system, separating large fragments and generating comparable genetic patterns. The agarose gel was then stained with GelRed® and photographed under ultraviolet transillumination. The PFGE patterns obtained from the 112 strains were compared using Bionumerics version 7.6 software with the Dice coefficient with 2% band tolerance and 2% optimization. For each serotype, the data obtained with the PFGE were compared according to the geographical origin and the year in which they were isolated. Salmonella strains were identified as follow: S. Derby n. 34; S. Infantis n. 38; S. Napoli n. 40. All the isolates had appreciable restricted digestion patterns ranging from approximately 40 to 1100 kb. In general, a fairly heterogeneous distribution of pulsotypes has emerged in the different provinces. Cluster analysis indicated high genetic similarity (≥ 83%) among strains of S. Derby (n. 30; 88%), S. Infantis (n. 36; 95%) and S. Napoli (n. 38; 95%) circulating in north-western Italy. The study underlines the genomic similarities shared by the emerging Salmonella strains in Northwest Italy and allowed to create a database to detect outbreaks in an early stage. Therefore, the results confirmed that PFGE is a powerful and discriminatory tool to investigate the genetic relationships among strains in order to monitoring and control Salmonellosis outbreak spread. Pulsed-field gel electrophoresis (PFGE) still represents one of the most suitable approaches to characterize strains, in particular for the laboratories for which NGS techniques are not available. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=emerging%20Salmonella%20serotypes" title="emerging Salmonella serotypes">emerging Salmonella serotypes</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20characterization" title=" genetic characterization"> genetic characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20strains" title=" human strains"> human strains</a>, <a href="https://publications.waset.org/abstracts/search?q=PFGE" title=" PFGE"> PFGE</a> </p> <a href="https://publications.waset.org/abstracts/148996/salmonella-emerging-serotypes-in-northwestern-italy-genetic-characterization-by-pulsed-field-gel-electrophoresis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/148996.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">105</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">41</span> Investigation of Glacier Activity Using Optical and Radar Data in Zardkooh</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mehrnoosh%20Ghadimi">Mehrnoosh Ghadimi</a>, <a href="https://publications.waset.org/abstracts/search?q=Golnoush%20Ghadimi"> Golnoush Ghadimi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Precise monitoring of glacier velocity is critical in determining glacier-related hazards. Zardkooh Mountain was studied in terms of glacial activity rate in Zagros Mountainous region in Iran. In this study, we assessed the ability of optical and radar imagery to derive glacier-surface velocities in mountainous terrain. We processed Landsat 8 for optical data and Sentinel-1a for radar data. We used methods that are commonly used to measure glacier surface movements, such as cross correlation of optical and radar satellite images, SAR tracking techniques, and multiple aperture InSAR (MAI). We also assessed time series glacier surface displacement using our modified method, Enhanced Small Baseline Subset (ESBAS). The ESBAS has been implemented in StaMPS software, with several aspects of the processing chain modified, including filtering prior to phase unwrapping, topographic correction within three-dimensional phase unwrapping, reducing atmospheric noise, and removing the ramp caused by ionosphere turbulence and/or orbit errors. Our findings indicate an average surface velocity rate of 32 mm/yr in the Zardkooh mountainous areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=active%20rock%20glaciers" title="active rock glaciers">active rock glaciers</a>, <a href="https://publications.waset.org/abstracts/search?q=landsat%208" title=" landsat 8"> landsat 8</a>, <a href="https://publications.waset.org/abstracts/search?q=sentinel-1a" title=" sentinel-1a"> sentinel-1a</a>, <a href="https://publications.waset.org/abstracts/search?q=zagros%20mountainous%20region" title=" zagros mountainous region"> zagros mountainous region</a> </p> <a href="https://publications.waset.org/abstracts/164979/investigation-of-glacier-activity-using-optical-and-radar-data-in-zardkooh" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/164979.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">77</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">40</span> Wound Healing Process Studied on DC Non-Homogeneous Electric Fields</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Marisa%20Rio">Marisa Rio</a>, <a href="https://publications.waset.org/abstracts/search?q=Sharanya%20Bola"> Sharanya Bola</a>, <a href="https://publications.waset.org/abstracts/search?q=Richard%20H.%20W.%20Funk"> Richard H.

Physiologically, cells experience electrical signals in the form of transmembrane potentials, ion fluxes through protein channels as well as electric fields at their surface. As soon as a wound is created, the disruption of the epithelial layers generates an electric field of ca. 40-200 mV/mm, directing cell migration towards the wound site, starting the healing process. In vitro electrotaxis, experiments have shown cells respond to DC EFs polarizing and migrating towards one of the poles (cathode or anode). A standard electrotaxis experiment consists of an electrotaxis chamber where cells are cultured, a DC power source and agar salt bridges that help delaying toxic products from the electrodes to attain the cell surface. The electric field strengths used in such an experiment are uniform and homogeneous. In contrast, the endogenous electric field strength around a wound tend to be multi-field and non-homogeneous. In this study, we present a custom device that enables electrotaxis experiments in non-homogeneous DC electric fields. Its main feature involves the replacement of conventional metallic electrodes, separated from the electrotaxis channel by agarose gel bridges, through electrolyte-filled microchannels. The connection to the DC source is made by Ag/AgCl electrodes, incased in agarose gel and placed at the end of each microfluidic channel. An SU-8 membrane closes the fluidic channels and simultaneously serves as the single connection from each of them to the central electrotaxis chamber. The electric field distribution and current density were numerically simulated with the steady-state electric conduction module from ANSYS 16.0. Simulation data confirms the application of nonhomogeneous EF of physiological strength. To validate the biocompatibility of the device cellular viability of the photoreceptor-derived 661W cell line was accessed. The cells have not shown any signs of apoptosis, damage or detachment during stimulation. Furthermore, immunofluorescence staining, namely by vinculin and actin labelling, allowed the assessment of adhesion efficiency and orientation of the cytoskeleton, respectively. Cellular motility in the presence and absence of applied DC EFs was verified. The movement of individual cells was tracked for the duration of the experiments, confirming the EF-induced, cathodal-directed motility of the studied cell line. The in vitro monolayer wound assay, or “scratch assay” is a standard protocol to quantitatively access cell migration in vitro. It encompasses the growth of a confluent cell monolayer followed by the mechanic creation of a scratch, representing a wound. Hence, wound dynamics was monitored over time and compared for control and applied the electric field to quantify cellular population motility. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=DC%20non-homogeneous%20electric%20fields" title="DC non-homogeneous electric fields">DC non-homogeneous electric fields</a>, <a href="https://publications.waset.org/abstracts/search?q=electrotaxis" title=" electrotaxis"> electrotaxis</a>, <a href="https://publications.waset.org/abstracts/search?q=microfluidic%20biochip" title=" microfluidic biochip"> microfluidic biochip</a>, <a href="https://publications.waset.org/abstracts/search?q=wound%20healing" title=" wound healing"> wound healing</a> </p> <a href="https://publications.waset.org/abstracts/47460/wound-healing-process-studied-on-dc-non-homogeneous-electric-fields" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/47460.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">270</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">39</span> 3D Label-Free Bioimaging of Native Tissue with Selective Plane Illumination Optical Microscopy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jing%20Zhang">Jing Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yvonne%20Reinwald"> Yvonne Reinwald</a>, <a href="https://publications.waset.org/abstracts/search?q=Nick%20Poulson"> Nick Poulson</a>, <a href="https://publications.waset.org/abstracts/search?q=Alicia%20El%20Haj"> Alicia El Haj</a>, <a href="https://publications.waset.org/abstracts/search?q=Chung%20See"> Chung See</a>, <a href="https://publications.waset.org/abstracts/search?q=Mike%20Somekh"> Mike Somekh</a>, <a href="https://publications.waset.org/abstracts/search?q=Melissa%20Mather"> Melissa Mather</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Biomedical imaging of native tissue using light offers the potential to obtain excellent structural and functional information in a non-invasive manner with good temporal resolution. Image contrast can be derived from intrinsic absorption, fluorescence, or scatter, or through the use of extrinsic contrast. A major challenge in applying optical microscopy to in vivo tissue imaging is the effects of light attenuation which limits light penetration depth and achievable imaging resolution. Recently Selective Plane Illumination Microscopy (SPIM) has been used to map the 3D distribution of fluorophores dispersed in biological structures. In this approach, a focused sheet of light is used to illuminate the sample from the side to excite fluorophores within the sample of interest. Images are formed based on detection of fluorescence emission orthogonal to the illumination axis. By scanning the sample along the detection axis and acquiring a stack of images, 3D volumes can be obtained. The combination of rapid image acquisition speeds with the low photon dose to samples optical sectioning provides SPIM is an attractive approach for imaging biological samples in 3D. To date all implementations of SPIM rely on the use of fluorescence reporters be that endogenous or exogenous. This approach has the disadvantage that in the case of exogenous probes the specimens are altered from their native stage rendering them unsuitable for in vivo studies and in general fluorescence emission is weak and transient. Here we present for the first time to our knowledge a label-free implementation of SPIM that has downstream applications in the clinical setting. The experimental set up used in this work incorporates both label-free and fluorescent illumination arms in addition to a high specification camera that can be partitioned for simultaneous imaging of both fluorescent emission and scattered light from intrinsic sources of optical contrast in the sample being studied. This work first involved calibration of the imaging system and validation of the label-free method with well characterised fluorescent microbeads embedded in agarose gel. 3D constructs of mammalian cells cultured in agarose gel with varying cell concentrations were then imaged. A time course study to track cell proliferation in the 3D construct was also carried out and finally a native tissue sample was imaged. For each sample multiple images were obtained by scanning the sample along the axis of detection and 3D maps reconstructed. The results obtained validated label-free SPIM as a viable approach for imaging cells in a 3D gel construct and native tissue. This technique has the potential use in a near-patient environment that can provide results quickly and be implemented in an easy to use manner to provide more information with improved spatial resolution and depth penetration than current approaches. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bioimaging" title="bioimaging">bioimaging</a>, <a href="https://publications.waset.org/abstracts/search?q=optics" title=" optics"> optics</a>, <a href="https://publications.waset.org/abstracts/search?q=selective%20plane%20illumination%20microscopy" title=" selective plane illumination microscopy"> selective plane illumination microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20imaging" title=" tissue imaging"> tissue imaging</a> </p> <a href="https://publications.waset.org/abstracts/56468/3d-label-free-bioimaging-of-native-tissue-with-selective-plane-illumination-optical-microscopy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56468.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">249</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Molecular Characterization and Determination of Bioremediation Potentials of Some Bacteria Isolated from Spent Oil Contaminated Soil Mechanic Workshops in Kaduna Metropolis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=David%20D.%20Adams">David D.

It is therefore suggested that a pilot study on the field application of these bacteria for bioremediation and restoration of spent oil polluted environment should be done in mechanic workshops. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spent%20engine%20oil" title="spent engine oil">spent engine oil</a>, <a href="https://publications.waset.org/abstracts/search?q=pollution" title=" pollution"> pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=bacteria" title=" bacteria"> bacteria</a>, <a href="https://publications.waset.org/abstracts/search?q=enzyme" title=" enzyme"> enzyme</a>, <a href="https://publications.waset.org/abstracts/search?q=bioremediation" title=" bioremediation"> bioremediation</a>, <a href="https://publications.waset.org/abstracts/search?q=mechanic%20workshop" title=" mechanic workshop"> mechanic workshop</a> </p> <a href="https://publications.waset.org/abstracts/78069/molecular-characterization-and-determination-of-bioremediation-potentials-of-some-bacteria-isolated-from-spent-oil-contaminated-soil-mechanic-workshops-in-kaduna-metropolis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78069.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">222</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Polymorphism in Myostatin Gene and Its Association with Growth Traits in Kurdi Sheep of Northern Khorasan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Masoud%20Alipanah">Masoud Alipanah</a>, <a href="https://publications.waset.org/abstracts/search?q=Sekineh%20Akbari"> Sekineh Akbari</a>, <a href="https://publications.waset.org/abstracts/search?q=Gholamreza%20Dashab"> Gholamreza Dashab</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Myostatin genes or factor 8 affecting on growth and making differentiation works (GDF8) as a moderator in the development of skeletal muscle inhibitor. If mutations occurs in the coding region of myostatin, alter its inhibitory role and the muscle growth is increased. In this study, blood samples were collected randomly from 60 Kurdish sheep in northern Khorasan and DNA extraction was performed using a modified salt. A fragment 337 bp from exon 3 myostatin gene and-specific primers by using a polymerase chain reaction (PCR) were amplified. In order to detect different forms of an allele at this locus HaeΙΙΙ restriction enzymes and PCR-RFLP analysis were used. Band patterns clarification was performed using agarose gel electrophoresis. The frequency of genotypes mm, Mm, and MM, were respectively detected, 0, 0.15 and 0.85. The allele frequency for alleles m and M, were respectively, 0.07 and 0.93. The statistical analyses indicated that m allele was significantly associated with body weight. The results of this study suggest that the Myostatin gene possibly is a candidate gene that affects growth traits in Kurdish sheep. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GDF8%20gene" title="GDF8 gene">GDF8 gene</a>, <a href="https://publications.waset.org/abstracts/search?q=Kurdi%20Sheep%20of%20Northern%20Khorasan" title=" Kurdi Sheep of Northern Khorasan"> Kurdi Sheep of Northern Khorasan</a>, <a href="https://publications.waset.org/abstracts/search?q=polymorphism" title=" polymorphism"> polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=weight%20traits" title=" weight traits"> weight traits</a> </p> <a href="https://publications.waset.org/abstracts/25104/polymorphism-in-myostatin-gene-and-its-association-with-growth-traits-in-kurdi-sheep-of-northern-khorasan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25104.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">340</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Forensic Methods Used for the Verification of the Authenticity of Prints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Olivia%20Rybak-Karkosz">Olivia Rybak-Karkosz</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper aims to present the results of scientific research on methods of forging art prints and their elements, such as signature or provenance and forensic science methods that might be used to verify their authenticity. In the last decades, the art market has observed significant interest in purchasing prints. They are considered an economical alternative to paintings and a considerable investment. However, the authenticity of an art print is difficult to establish as similar visual effects might be achieved with drawings or xerox. The latter is easy to make using a home printer. They are then offered on flea markets or internet auctions as genuine prints. This probable ease of forgery and, at the same time, the difficulty of distinguishing art print techniques were the main reasons why this research was undertaken. A lack of scientific methods dedicated to disclosing a forgery encouraged the author to verify the possibility of using forensic science's methods known and used in other fields of expertise. This research methodology consisted of completing representative forgery samples collected in selected museums based in Poland and a few in Germany and Austria. That allowed the author to present a typology of methods used to forge art prints. Given that one of the most famous graphic design examples is bills and securities, it seems only appropriate to propose in print verification the usage of methods of detecting counterfeit currency. These methods contain an examination of ink, paper, and watermarks. On prints, additionally, signatures and imprints of stamps, etc., are forged as well. So the examination should be completed with handwriting examination and forensic sphragistics. The paper contains a stipulation to conduct a complex analysis of authenticity with the participation of an art restorer, art historian, and forensic expert as head of this team. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=art%20forgery" title="art forgery">art forgery</a>, <a href="https://publications.waset.org/abstracts/search?q=examination%20of%20an%20artwork" title=" examination of an artwork"> examination of an artwork</a>, <a href="https://publications.waset.org/abstracts/search?q=handwriting%20analysis" title=" handwriting analysis"> handwriting analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=prints" title=" prints"> prints</a> </p> <a href="https://publications.waset.org/abstracts/152763/forensic-methods-used-for-the-verification-of-the-authenticity-of-prints" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152763.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">129</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">35</span> Evaluation of Genetic Diversity in Iranian Native Silkworm Bombyx mori Using RAPD (Random Amplification of Polymorphic DNA) Molecular Marker</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rouhollah%20Radjabi">Rouhollah Radjabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mojtaba%20Zarei"> Mojtaba Zarei</a>, <a href="https://publications.waset.org/abstracts/search?q=Elham%20Sanatgar"> Elham Sanatgar</a>, <a href="https://publications.waset.org/abstracts/search?q=Hossein%20Shouhani"> Hossein Shouhani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> RAPD molecular markers in order to discrimination of the Iranian native Bombyx mori silkworm breeds were used.

This art thrived gradually and continued its development as an independent art. Identification of the binding techniques and used materials in covers and investigation of the arrays give us indexes for the better identification of different doctrines and methods of that time. The catalogers of the manuscripts usually pay attention to four items: gender, color, art elegances, injury, and exquisiteness of the cover. The criterion for classification of the covers is their art nature and gender. 15th century AD (9th century AH) was the period of the binding art development in which the most beautiful covers were produced by the so-called method of ‘burning’. At 16th century AD (10th century AH), in Safavid era, art changed completely and a fundamental evolution occurred in the technique and method of binding. The greatest change in this art was the extensive use of stamp that was made mostly of steel and copper. Theses stamps were presses against leather. These covers were called ‘beat’. In this paper, writing and bookbinding of about 32 Shahnamehs of Safavid era available in the Iranian libraries and museums are studied. An analytical-statistical study shows that four methods have been used including beat, burning, mosaic, and oily. 69 percent of the covers of these copies are cardboards with a leathery coating (goatskin) and have been produced by burning and beat methods. Its reasons are that these two methods have been common methods in Safavid era and performing them was only feasible on leather and the most desirable and commonly used leather of that time was goatskin which was the best option for cover legend durability and preserving the book and it was more durable because it had been made of goat skin. In addition, it had prepared a suitable opportunity for the binding artist’s creativity and innovation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahnameh" title="Shahnameh">Shahnameh</a>, <a href="https://publications.waset.org/abstracts/search?q=Safavid%20era" title=" Safavid era"> Safavid era</a>, <a href="https://publications.waset.org/abstracts/search?q=bookbinding" title=" bookbinding"> bookbinding</a>, <a href="https://publications.waset.org/abstracts/search?q=beat%20cover" title=" beat cover"> beat cover</a>, <a href="https://publications.waset.org/abstracts/search?q=burning%20cover" title=" burning cover"> burning cover</a> </p> <a href="https://publications.waset.org/abstracts/34892/a-study-of-binding-methods-and-techniques-in-safavid-era-emphasizing-on-iran-shahnamehs-16-18th-century-ad10-12th-century-ah" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34892.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">238</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">33</span> Serological Assay and Genotyping of Hepatitis C Virus in Infected Patients in Zanjan Province</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abdolreza%20Esmaeilzadeh">Abdolreza Esmaeilzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Erfanmanesh"> Maryam Erfanmanesh</a>, <a href="https://publications.waset.org/abstracts/search?q=Sousan%20Ghasemi"> Sousan Ghasemi</a>, <a href="https://publications.waset.org/abstracts/search?q=Farzaneh%20Mohammadi"> Farzaneh Mohammadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Hepatitis C Virus (HCV), a public health problem, is an enveloped, single-stranded RNA virus and a member of the Hepacivirus genus of the Flaviviridae family. Liver cancer, cirrhosis, and end-stage liver are the outcomes of chronic infection with HCV. HCV isolates show significant heterogeneity in genetics around the world. Therefore, determining HCV genotypes is a vital step in determining prognosis and planning therapeutic strategies. Materials and Methods: Serum samples of 136 patients were collected and analyzed for anti-HCV antibodies using ELISA (The enzyme-linked immunosorbent assay) method. Then, positive samples were exposed to RT-PCR, which was performed under standard condition. Afterwards, they investigated for genotyping using allele-specific PCR (AS-PCR), and HCV genotype 2.0 line probe assay (LiPA). Results: Samples indicated 216 bp bands on 2% agarose gel. Analyses of the results demonstrated that the most dominant subtype was 3a with frequency of 38.26% in Zanjan Province followed by subtypes of 1b, 1a, 2, and 4 with frequencies of 25.73%, 22.05%, 5.14%, and 4.41%, respectively. The frequency of unknown HCV genotypes was 4.41%. Conclusions: According to the results, it was found that HCV high prevalent genotype in Zanjan is subtype 3a. Analysis of the results provides identification of certain HCV genotypes, and these valuable findings could affect the type and duration of the treatment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anti-HCV%20antibody" title="anti-HCV antibody">anti-HCV antibody</a>, <a href="https://publications.waset.org/abstracts/search?q=Hepatitis%20C%20Virus%20%28HCV%29" title=" Hepatitis C Virus (HCV)"> Hepatitis C Virus (HCV)</a>, <a href="https://publications.waset.org/abstracts/search?q=genotype" title=" genotype"> genotype</a>, <a href="https://publications.waset.org/abstracts/search?q=RT-PCR" title=" RT-PCR"> RT-PCR</a>, <a href="https://publications.waset.org/abstracts/search?q=AS-PCR" title=" AS-PCR "> AS-PCR </a> </p> <a href="https://publications.waset.org/abstracts/23761/serological-assay-and-genotyping-of-hepatitis-c-virus-in-infected-patients-in-zanjan-province" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/23761.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">489</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">32</span> Purification and Pre-Crystallization of Recombinant PhoR Cytoplasmic Domain Protein from Mycobacterium Tuberculosis H37Rv</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oktira%20Roka%20Aji">Oktira Roka Aji</a>, <a href="https://publications.waset.org/abstracts/search?q=Maelita%20R.%20Moeis"> Maelita R.

The emergence of multidrug-resistant strains and extensively drug-resistant strains have become a major public concern. One of the potential candidates for drug target is the cytoplasmic domain of PhoR Histidine Kinase, a part of the Two Component System (TCS) PhoR-PhoP in Mycobacterium tuberculosis (Mtb). TCS PhoR-PhoP relay extracellular signal to control the expression of 114 virulent associated genes in Mtb. The 3D structure of PhoR cytoplasmic domain is needed to screen novel drugs using structure based drug discovery. The PhoR cytoplasmic domain from Mtb H37Rv was overexpressed in E. coli BL21(DE3), then purified using IMAC Ni-NTA Agarose his-tag affinity column and DEAE-ion exchange column chromatography. The molecular weight of the purified protein was estimated to be 37 kDa after SDS-PAGE analysis. This sample was used for pre-crystallization screening by applying sitting drop vapor diffusion method using Natrix (HR2-116) 48 solutions crystal screen kit at 25ºC. Needle-like crystals were observed after the seventh day of incubation in test solution No.47 (0.1 M KCl, 0.01 M MgCl2.6H2O, 0.05 M Tris-Cl pH 8.5, 30% v/v PEG 4000).

Wheat seed proteins were divided into four groups according to solubility. Two groups are albumin and globulin dissolving in water and salt solutions possessing metabolic activities. Two other groups are inactive and non-dissolvable and contain glutelins or glutenins and prolamins or gliadins. Gliadins are major components of the storage proteins in wheat endosperm. Gliadin proteins are separated into three groups based on electrophoretic mobility: α/β-gliadin, γ-gliadin, and ω-gliadin. It seems that little information is available about gliadin genes in Iranian wild relatives of wheat. Thus, the aim of this study was the evaluation of the wheat wild relatives collected from different origins of Zagros Mountains in Iran, involving coding gliadin genes using specific primers. For this, forty accessions of Triticum boeoticum and Triticum urartu were selected. For each accession, genomic DNA was extracted and PCRs were performed in total volumes of 15 μl. The amplification products were separated on 1.5% agarose gels. In results, for Gli-2A locus, three allelic variants were detected by Gli-2As primer pairs. The sizes of PCR products for these alleles were 210, 490 and 700 bp. Only five (13%) and two accessions (5%) produced 700 and 490 bp fragments when their DNA was ampliﬁed with the Gli.As.2 primer pairs. However, 37 of the 40 accessions (93%) carried 210 bp allele, and three accessions (8%) did not yield any product for this marker. Therefore, these germplasm could be used as rich gene pool to broaden the genetic base of bread wheat. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diploied%20wheat" title="diploied wheat">diploied wheat</a>, <a href="https://publications.waset.org/abstracts/search?q=gliadin" title=" gliadin"> gliadin</a>, <a href="https://publications.waset.org/abstracts/search?q=Triticum%20boeoticum" title=" Triticum boeoticum"> Triticum boeoticum</a>, <a href="https://publications.waset.org/abstracts/search?q=Triticum%20urartu" title=" Triticum urartu"> Triticum urartu</a> </p> <a href="https://publications.waset.org/abstracts/38120/identification-and-classification-of-gliadin-genes-in-iranian-diploid-wheat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38120.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">252</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">30</span> Natural Honey and Effect on the Activity of the Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abujnah%20Dukali">Abujnah Dukali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Natural honey was assessed in cell culture system for its anticancer activity. Human leukemic cell line HL 60 was treated with honey and cultured for 5 days and cytotoxicity was calculated by MTT assay. Honey showed cytotoxicity with CC50 value of 174.20 µg/ml. Radical modulation activities was assessed by lipid peroxidation assay using egg lecithin. Honey showed antioxidant activity with EC50 value of 159.73 µg/ml. In addition, treatment with HL60 cells also resulted in nuclear DNA fragmentation, as seen in agarose gel electrophoresis. This is a hallmark of cells undergoing apoptosis. Confirmation of apoptosis was performed by staining the cells with Annexin V and FACS analysis. Apoptosis is an active, genetically regulated disassembly of the cell form within. Disassembly creates changes in the phospholipid content of the cytoplasmic membrane outer leaflet. Phosphatidylserine (PS) is translocated from the inner to the outer surface of the cell for phagocytic cell recognition. The human anticoagulant, annexin V, is a Ca2+-dependent phospholipid protein with a high affinity for PS. Annexin V labeled with fluorescein can identify apoptotic cells in the population It is a confirmatory test for apoptosis. Annexin V-positive cells were defined as apoptotic cells. Since honey shows both antioxidant activity and cytotoxicity at almost the same concentration, it can prevent the free radical induced cancer as prophylactic agent and kill the cancer cells by apoptotic process as a chemotherapeutic agent. Everyday intake of honey can prevent the cancer induction. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anticancer" title="anticancer">anticancer</a>, <a href="https://publications.waset.org/abstracts/search?q=cells" title=" cells"> cells</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA" title=" DNA"> DNA</a>, <a href="https://publications.waset.org/abstracts/search?q=honey" title=" honey"> honey</a> </p> <a href="https://publications.waset.org/abstracts/44196/natural-honey-and-effect-on-the-activity-of-the-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/44196.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">206</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Assessment of DNA Degradation Using Comet Assay: A Versatile Technique for Forensic Application</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ritesh%20K.%20Shukla">Ritesh K.

Currently, there are no precise methods available to circumvent this problem. Therefore, at the preliminary level, some methods are urgently needed to solve this issue. In this order, Comet assay is one of the most versatile, rapid and sensitive molecular biology technique to assess the DNA degradation. This technique helps to assess DNA degradation even at very low amount of sample. Moreover, the expedient part of this method does not require any additional process of DNA extraction and isolation during DNA degradation assessment. Samples directly embedded on agarose pre-coated microscopic slide and electrophoresis perform on the same slide after lysis step. After electrophoresis microscopic slide stained by DNA binding dye and observed under fluorescent microscope equipped with Komet software. With the help of this technique extent of DNA degradation can be assessed which can help to screen the sample before DNA fingerprinting, whether it is appropriate for DNA analysis or not. This technique not only helps to assess degradation of DNA but many other challenges in forensic investigation such as time since deposition estimation of biological fluids, repair of genetic material from degraded biological sample and early time since death estimation could also be resolved. With the help of this study, an attempt was made to explore the application of well-known molecular biology technique that is Comet assay in the field of forensic science. This assay will open avenue in the field of forensic research and development. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comet%20assay" title="comet assay">comet assay</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20degradation" title=" DNA degradation"> DNA degradation</a>, <a href="https://publications.waset.org/abstracts/search?q=forensic" title=" forensic"> forensic</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20biology" title=" molecular biology"> molecular biology</a> </p> <a href="https://publications.waset.org/abstracts/88073/assessment-of-dna-degradation-using-comet-assay-a-versatile-technique-for-forensic-application" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88073.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">155</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Comet Assay: A Promising Tool for the Risk Assessment and Clinical Management of Head and Neck Tumors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sarim%20Ahmad">Sarim Ahmad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Single Cell Gel Electrophoresis Assay (SCGE, known as comet assay) is a potential, uncomplicated, sensitive and state-of-the-art technique for quantitating DNA damage at individual cell level and repair from in vivo and in vitro samples of eukaryotic cells and some prokaryotic cells, being popular in its widespread use in various areas including human biomonitoring, genotoxicology, ecological monitoring and as a tool for research into DNA damage or repair in different cell types in response to a range of DNA damaging agents, cancer risk and therapy. The method involves the encapsulation of cells in a low-melting-point agarose suspension, lysis of the cells in neutral or alkaline (pH > 13) conditions, and electrophoresis of the suspended lysed cells, resulting in structures resembling comets as observed by fluorescence microscopy; the intensity of the comet tail relative to the head reflects the number of DNA breaks. The likely basis for this is that loops containing a break lose their supercoiling and become free to extend towards the anode. This is followed by visual analysis with staining of DNA and calculating fluorescence to determine the extent of DNA damage. This can be performed by manual scoring or automatically by imaging software. The assay can, therefore, predict an individual’s tumor sensitivity to radiation and various chemotherapeutic drugs and further assess the oxidative stress within tumors and to detect the extent of DNA damage in various cancerous and precancerous lesions of oral cavity. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comet%20assay" title="comet assay">comet assay</a>, <a href="https://publications.waset.org/abstracts/search?q=single%20cell%20gel%20electrophoresis" title=" single cell gel electrophoresis"> single cell gel electrophoresis</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20damage" title=" DNA damage"> DNA damage</a>, <a href="https://publications.waset.org/abstracts/search?q=early%20detection%20test" title=" early detection test"> early detection test</a> </p> <a href="https://publications.waset.org/abstracts/36851/comet-assay-a-promising-tool-for-the-risk-assessment-and-clinical-management-of-head-and-neck-tumors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/36851.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">292</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Antioxidant Juice Prevents UV- Induced Skin Damage in Rats</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20P.%20Gomes">S.

Phytonutrients demonstrate protective effects against UV damage. The purpose of this study was evaluating the effect of an antioxidant juice (AJ) contaning Brazilian natural products upon skin damage. The juice was produced by Metabolics®. Male Wistar rats were divided in 4 groups: Animals receiving the antioxidant juice (AJ): orange, carrot, honey, tomato extract, avocado, ginger and camu-camu (Brazilian fruit, a major source of vitamin C) ad libitum for 21 days; or water (C), subdivided in groups exposed or not to UV radiation for 2 non consecutive days, during five hours each day, after 15 days of juice supplementation. On the 22nd day, rats were killed by decapitation and epithelium samples from the dorsal skin removed, fixed in bouin and embedded in paraffin. The sections were stained with hematoxylin and eosin or mallory and picrosirius red. Isolated DNA was submitted to electrophoresis (1.8% agarose gel, 0.5% ethidium bromide). UV radiation significantly induced sunburn of superficial epithelial cells of C, AJ treatment reduced this effect. Collagen changes were observed in UV groups, yet AJ treatment prevented collagen degradation. UV radiation induced significant DNA degradation, in C, which was prevented by AJ treatment. The antioxidant juice consumed chronically protected against acute skin damage. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nutraceuticals" title="nutraceuticals">nutraceuticals</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidants" title=" antioxidants"> antioxidants</a>, <a href="https://publications.waset.org/abstracts/search?q=photoprotection" title=" photoprotection"> photoprotection</a>, <a href="https://publications.waset.org/abstracts/search?q=uv%20radiation" title=" uv radiation"> uv radiation</a> </p> <a href="https://publications.waset.org/abstracts/33120/antioxidant-juice-prevents-uv-induced-skin-damage-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/33120.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">624</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">26</span> Apolipoprotein A1 -75 G to a Substitution and Its Relationship with Serum ApoA1 Levels among Indian Punjabi Population</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Savjot%20Kaur">Savjot Kaur</a>, <a href="https://publications.waset.org/abstracts/search?q=Mridula%20Mahajan"> Mridula Mahajan</a>, <a href="https://publications.waset.org/abstracts/search?q=AJS%20Bhanwer"> AJS Bhanwer</a>, <a href="https://publications.waset.org/abstracts/search?q=Santokh%20Singh"> Santokh Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Kawaljit%20Matharoo"> Kawaljit Matharoo</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Disorders of lipid metabolism and genetic predisposition are CAD risk factors. ApoA1 is the apolipoprotein component of anti-atherogenic high density lipoprotein (HDL) particles. The protective action of HDL and ApoA1 is attributed to their central role in reverse cholesterol transport (RCT). Aim: This study was aimed at identifying sequence variations in ApoA1 (-75G>A) and its association with serum ApoA1 levels. Methods: A total of 300 CAD patients and 300 Normal individuals (controls) were analyzed. PCR-RFLP method was used to determine the DNA polymorphism in the ApoA1 gene, PCR products digested with restriction enzyme MspI, followed by Agarose Gel Electrophoresis. Serum apolipoprotein A1 concentration was estimated with immunoturbidimetric method. Results: Deviation from Hardy- Weinberg Equilibrium (HWE) was observed for this gene variant. The A- allele frequency was higher among Coronary Artery disease patients (53.8) compared to controls (45.5), p= 0.004, O.R= 1.38(1.11-1.75). Under recessive model analysis (AA vs. GG+GA) AA genotype of ApoA1 G>A substitution conferred ~1 fold increased risk towards CAD susceptibility (p= 0.002, OR= 1.72(1.2-2.43). With serum ApoA1 levels < 107 A allele frequency was higher among CAD cases (50) as compared to controls (43.4) [p=0.23, OR= 1.2(0.84-2)] and there was zero % occurrence of A allele frequency in individuals with ApoA1 levels > 177. Conclusion: Serum ApoA1 levels were associated with ApoA1 promoter region variation and influence CAD risk. The individuals with the APOA1 -75 A allele confer excess hazard of developing CAD as a result of its effect on low serum concentrations of ApoA1. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apolipoprotein%20A1%20%28G%3EA%29%20gene%20polymorphism" title="apolipoprotein A1 (G>A) gene polymorphism">apolipoprotein A1 (G>A) gene polymorphism</a>, <a href="https://publications.waset.org/abstracts/search?q=coronary%20artery%20disease%20%28CAD%29" title=" coronary artery disease (CAD)"> coronary artery disease (CAD)</a>, <a href="https://publications.waset.org/abstracts/search?q=reverse%20cholesterol%20transport%20%28RCT%29" title=" reverse cholesterol transport (RCT)"> reverse cholesterol transport (RCT)</a> </p> <a href="https://publications.waset.org/abstracts/41216/apolipoprotein-a1-75-g-to-a-substitution-and-its-relationship-with-serum-apoa1-levels-among-indian-punjabi-population" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41216.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">317</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Prevalence of Extended Spectrum of Beta Lactamase Producers among Gram Negative Uropathogens</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Y.%20V.%20S.%20Annapurna">Y.

This is further augmented by increase in the number of resistant and multi resistant strains of bacteria particularly by those producing Extended spectrum of beta lactamases. The present study was aimed at analysis of antibiograms of E.coli and Klebsiella sp causing urinary tract infections. Between November 2011 and April 2013, a total of 1120 urine samples were analyzed,. Antibiotic sensitivity testing was done with 542(48%) isolates of E.coli and 446(39%) of Klebsiella sp using the standard disc diffusion method against eleven commonly used antibiotics .Organisms showed high susceptibility to Amikacin and Netilimicin and low susceptibility to Cephalosporins. MAR index was calculated for the multidrug resistant strains. Maximum MAR index detected among the isolates was 0.9. Phenotypic identification for ESBL production was confirmed by double disk synergy test (DDST) according to CLSI guidelines. Plasmid profile of the isolates was carried out using alkaline hydrolysis method. Agarose-gel electrophoresis showed presence of high-molecular weight plasmid DNA among the ESBL strains. This study emphasizes the importance of indiscriminate use of antibiotics which if discontinued, in turn would prevent further development of bacterial drug resistance. For this, a proper knowledge of susceptibility pattern of uropathogens is necessary before prescribing empirical antibiotic therapy and it should be made mandatory. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=escherichia%20coli" title="escherichia coli">escherichia coli</a>, <a href="https://publications.waset.org/abstracts/search?q=extended%20spectrum%20%20of%20beta%20%20%20%20%20%20%20%20lactamase" title=" extended spectrum of beta lactamase"> extended spectrum of beta lactamase</a>, <a href="https://publications.waset.org/abstracts/search?q=Klebsiella%20spp" title=" Klebsiella spp"> Klebsiella spp</a>, <a href="https://publications.waset.org/abstracts/search?q=Uropathogens" title=" Uropathogens"> Uropathogens</a> </p> <a href="https://publications.waset.org/abstracts/24691/prevalence-of-extended-spectrum-of-beta-lactamase-producers-among-gram-negative-uropathogens" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/24691.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">366</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">24</span> Molecular Characterization of Dirofilaria repens in Dogs from Karnataka, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=D.%20S.%20Malatesh">D.

D. repens is reported in many countries, including India. Subcutaneous dirofilariosis caused by D. repens is a zoonotic disease, widely distributed throughout Europe, Asia, and Africa, with higher prevalence reported in dogs from Sri Lanka (30-60%), Iran (61%) and Italy (21-25%). Dirofilariasis in dogs was diagnosed by detection of microfilariae in blood. Identification of different Dirofilaria species was done by using molecular methods like polymerase chain reaction (PCR). Even though many researchers reported molecular evidence of D. repens across India, to our best knowledge there is no data available on molecular diagnosis of D. repens in dogs and its zoonotic implication in Karnataka state a southern state in India. The aim of the present study was to identify the Dirofilaria species occurring in dogs from Karnataka, India. Out of 310 samples screened for the presence of microfilariae using traditional diagnostic methods, 99 (31.93%) were positive for the presence of microfilariae. Based on the morphometry, the microfilariae were identified as D. repens. For confirmation of species, the samples were subjected to PCR using pan filarial primers (DIDR-F1, DIDR-R1) for amplification of internal transcribed spacer region 2 (ITS2) of the ribosomal DNA. The PCR product of 484 base pairs on agarose gel was indicative of D. repens. Hence, a single PCR reaction using pan filarial primers can be used to differentiate filarial species found in dogs. The present study confirms that dirofilarial species occurring in dogs from Karnataka is D. repens and further sequencing studies are needed for genotypic characterization of D. repens. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dirofilaria%20repens" title="Dirofilaria repens">Dirofilaria repens</a>, <a href="https://publications.waset.org/abstracts/search?q=molecular%20characterization" title=" molecular characterization"> molecular characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=polymerase%20chain%20reaction" title=" polymerase chain reaction"> polymerase chain reaction</a>, <a href="https://publications.waset.org/abstracts/search?q=Karnataka" title=" Karnataka"> Karnataka</a>, <a href="https://publications.waset.org/abstracts/search?q=India" title=" India"> India</a> </p> <a href="https://publications.waset.org/abstracts/109804/molecular-characterization-of-dirofilaria-repens-in-dogs-from-karnataka-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/109804.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">142</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">23</span> Infectivity of Hyalomma Ticks for Theileria annulata Using 18s rRNA PCR </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Muhammad%20S.%20Sajid">Muhammad S.

Similarly, among various tick-borne pathogens, Theileria (T.) annulata, the causative agent of tropical theileriosis in large ruminants, is responsible for reduced productivity and ultimately substantial economic losses due to morbidity and mortality. The present study was planned to screening of vector ticks through molecular techniques for determination of tick-borne theileriosis in district Toba Tek Singh (T. T. Singh), Punjab, Pakistan. For this purpose, among the collected ticks (n = 2252) from livestock and their microclimate, Hyalomma spp. were subjected to dissection for procurement of salivary glands (SGs) and formation of pool (averaged 8 acini in each pool). Each pool of acini was used for DNA extraction, quantification and primer-specific amplification of 18S rRNA of Theileria (T.) annulata. The amplicons were electrophoresed using 1.8% agarose gel following by imaging to identify the band specific for T. annulata. For confirmation, the positive amplicons were subjected to sequencing, BLAST analysis and homology search using NCBI software. The number of Theileria-infected acini was significantly higher (P < 0.05) in female ticks vs male ticks, infesting ticks vs questing ticks and riverine-collected vs non-riverine collected. The data provides first attempt to quantify the vectoral capacity of ixodid ticks in Pakistan for T. annulata which can be helpful in estimation of risk analysis of theileriosis to the domestic livestock population of the country. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hyalomma%20anatolicum" title="Hyalomma
