Laboratory experiments were carried out on the effect of different concentrations of Incense smoke inhalation on the lung weight and tissue in female mice. This research derives its importance from the fact that Incense is heavily used in Saudi Arabia in the absence of thorough studies of its effects on health. Eighty animals are used in this study, and they are divided into four groups, each is 20 animals. Three groups are exposed to different concentrations (2, 4 and 6 gm) of Incense smoke daily for three months, and the fourth group is the control. At the end of each month, five animals from each group were dissected. Obtained data showed an increase but not significant in animal body and lung weight, this results return to natural increase as a result of normal growth of animals. Light microscope reveals some changes in the lung tissue, such as focal emphysema, rupture in the alveolar walls, hemorrhage, congestion, edema and few peri-bronchial lymphoid cells. After continuous exposure to Incense smoke focal necrosis and degradation are observed in some cells of epithelial bronchioles. Also, fibrosis of peri-bronchial, thickening in alveolar walls and aggregation of lymphoid cells are demonstrated in some lungs sections. according to the above manifestations it could be concluded that exposure to Incense smoke causes pulmonary harmful effects. Therefore, we can recommend that Incense smoke will be used only in open places to reduce its harms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=incense%20smoke" title="incense smoke">incense smoke</a>, <a href="https://publications.waset.org/abstracts/search?q=lungs" title=" lungs"> lungs</a>, <a href="https://publications.waset.org/abstracts/search?q=histological%20changes%20of%20lungs" title=" histological changes of lungs"> histological changes of lungs</a>, <a href="https://publications.waset.org/abstracts/search?q=agarwood" title=" agarwood"> agarwood</a> </p> <a href="https://publications.waset.org/abstracts/27013/histological-changes-of-mice-lungs-after-daily-exposure-to-different-concentration-of-incense-smoke" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27013.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">493</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">441</span> Assessment of Cell-Rebuilding Efficacy of Selected Food Plants in the Lungs of Wild Rats Living in a Polluted Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yahaya%20Tajudeen">Yahaya Tajudeen</a>, <a href="https://publications.waset.org/abstracts/search?q=Joy%20Okpuzor"> Joy Okpuzor</a>, <a href="https://publications.waset.org/abstracts/search?q=Tolu%20Ajayi"> Tolu Ajayi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The cell-rebuilding efficacy of four food plants eating as vegetables and spices in Nigeria was assessed in the lungs of wild rats (Rattus rattus) living in a polluted environment. The plants are roselle (Hibiscus sabdarrifa), moringa (Moringa oleifera), ginger (Zingiber officinale) and ugwu (Telfairia occidentalis). Sixty rats were caught from the vicinity of a cement factory in Sagamu, Southwestern-Nigeria and grouped into 6. The control group was administered distilled water, while the test groups were given ethanolic extracts of roselle, moringa, ginger, ugwu and the mixture of the extracts for 180 days. The histopathology of the rats was conducted before and at the end of 180 days extracts administration. Before administering the extracts, the lungs of the rats showed vascular congestion, severe fibrosis and congested alveolus; all which were also observed in the lungs of control rats at the end of the treatment. However, the lungs of rats that were treated with the extracts of the plants showed moderate, mild or no histological damage compared to the control rats. The extract of the mixture of the plants performed best, followed by ginger, ugwu and roselle, respectively. These findings suggest that the food plants contain phytonutrients and phytochemicals, which repaired damaged cells and tissues in the exposed rats. Consequently, the plants could play a role in ameliorating health effects of environmental pollution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=food%20plants" title="food plants">food plants</a>, <a href="https://publications.waset.org/abstracts/search?q=wild%20rats" title=" wild rats"> wild rats</a>, <a href="https://publications.waset.org/abstracts/search?q=lung" title=" lung"> lung</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathology" title=" histopathology"> histopathology</a>, <a href="https://publications.waset.org/abstracts/search?q=fibrosis" title=" fibrosis"> fibrosis</a>, <a href="https://publications.waset.org/abstracts/search?q=cell-rebuilding" title=" cell-rebuilding"> cell-rebuilding</a> </p> <a href="https://publications.waset.org/abstracts/28191/assessment-of-cell-rebuilding-efficacy-of-selected-food-plants-in-the-lungs-of-wild-rats-living-in-a-polluted-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/28191.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">367</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">440</span> Estimation of Respiratory Parameters in Pressure Controlled Ventilation System with Double Lungs on Secretion Clearance </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qian%20Zhang">Qian Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Dongkai%20Shen"> Dongkai Shen</a>, <a href="https://publications.waset.org/abstracts/search?q=Yan%20Shi"> Yan Shi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A new mechanical ventilator with automatic secretion clearance function can improve the secretion clearance safely and efficiently. However, in recent modeling studies on various mechanical ventilators, it was considered that human had one lung, and the coupling effect of double lungs was never illustrated. In this paper, to expound the coupling effect of double lungs, a mathematical model of a ventilation system of a bi-level positive airway pressure (BiPAP) controlled ventilator with secretion clearance was set up. Moreover, an experimental study about the mechanical ventilation system of double lungs on BiPAP ventilator was conducted to verify the mathematical model. Finally, the coupling effect of double lungs of the mathematical ventilation was studied by simulation and orthogonal experimental design.

There are two clinically significant cytokines, IL-6 and TNF-α, which increase in levels in patients with severe COVID-19. However, in a model of COVID-19 in hamsters, TNF-α levels are unchanged or reduced, while the expression of other cytokines reflects the profile of cytokines found in patients’ plasma. The aim of our study was to evaluate the relationship between the level of cytokines in the blood, lungs, and lung damage in the model of the Syrian hamster (Mesocricetus auratus) infected with the SARS-CoV-2 strain. The study used outbred female and male Syrian hamsters (n=36, 4 groups) weighing 80-110 g and 5 months old (protocol IACUC, #4, 09/22/2020). Animals were infected intranasally with the hCoV-19/Kazakhstan/KazNAU-NSCEDI-481/2020 strain and euthanized at 3 d.p.i. The level of cytokines IL-6, TNF-α, IFN-α, and IFN-γ was determined by ELISA MyBioSourse (USA) for hamsters. Lung samples were subjected to histological processing. The presence of pathological changes in histological preparations was assessed on a 3-point scale. The work was carried out in the ABSL-3 laboratory. The data were analyzed in GraphPad Prism 6.00 (GraphPad Software, La Jolla, California, USA). The work was supported by the MES RK grant (AP09259865). In the blood, the level of TNF-α increased in males (p=0.0012) and IFN-γ in males and females (p=0.0001). On the contrary, IFN-α production decreased (p=0.0006). Only TNF-α level increased in lung tissues (p=0.0011). Correlation analysis showed a negative relationship between the level of IL-6 in the blood and lung damage in males (r -0.71, p=0.0001) and females (r-0.57, p=0.025). On the contrary, in males, the level of IL-6 in the lungs and score is positively correlated (r 0.80, p=0.01). The level of IFN-γ in the blood (r -0.64, p=0.035) and lungs (r-0.72, p=0.017) in males has a negative correlation with lung damage. No links were found for TNF-α and IFN-α. The study showed a positive association between lung injury and tissue levels of IL-6 in male hamsters. It is known that in humans, high concentrations of IL-6 in the lungs are associated with suppression of cellular immunity and, as a result, with an increase in the severity of COVID-19. TNF-α and IFN-γ play a key role in the pathogenesis of COVID-19 in hamsters. However, the mechanisms of their activity require more detailed study. IFN-α plays a lesser role in direct lung injury in a Syrian hamster model. We have shown the significance of tissue IL-6 and IFN-γ as predictors of the severity of lung damage in COVID-19 in the Syrian hamster model. Changes in the level of cytokines in the blood may not always reflect pathological processes in the lungs with COVID-19. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=syrian%20hamster" title="syrian hamster">syrian hamster</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19" title=" COVID-19"> COVID-19</a>, <a href="https://publications.waset.org/abstracts/search?q=cytokines" title=" cytokines"> cytokines</a>, <a href="https://publications.waset.org/abstracts/search?q=biological%20model" title=" biological model"> biological model</a> </p> <a href="https://publications.waset.org/abstracts/156510/correlation-between-cytokine-levels-and-lung-injury-in-the-syrian-hamster-mesocricetus-auratus-covid-19-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/156510.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">92</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">438</span> The Effects of Red Onion Extract (Allium ascalonicum L.) in the Pulmonary Histopathological Lesions of Layer Chickens at 47 Days Old Raised in the Battery Cage</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=R.%20N.%20Nataria">R.

The red onion (Allium ascalonicum L.) is a plant that contains flavonoid and saponin. Flavonoid is useful as anti-inflammatory and antioxidant while saponin is useful as antivirus, anti-inflammatory, antifungal, and immunomodulator. This study aimed to know and determine the effect of onion extracts to pulmonary histopathological lesions in layer chickens which raised in the battery cage. This study used eighteen layer chickens at seventeen days old. The eighteen layer chickens were divided into three groups of six each, namely without administration of red onion extract (Group I), with administration red onion extract through drinking water (Group II) and with administration red onion extract peroral (Group III). Every ten days, six chickens were necropsied and then the lungs were processed for histopathological preparations and stained with routine hematoxylin and eosin. The results showed that the lungs of the Group I had severe congestion and diffuse hemorrhages. In Group II, lungs had moderate congestion and hemorrhages. In group III, lungs had mild congestion and hemorrhages. It is concluded, that red onion extract apparently has reduced the lungs lesions in layer chickens. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=histopathological%20lesions" title="histopathological lesions">histopathological lesions</a>, <a href="https://publications.waset.org/abstracts/search?q=layers" title=" layers"> layers</a>, <a href="https://publications.waset.org/abstracts/search?q=lungs" title=" lungs"> lungs</a>, <a href="https://publications.waset.org/abstracts/search?q=poultry%20diseases" title=" poultry diseases"> poultry diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=red%20onion%20extract" title=" red onion extract"> red onion extract</a> </p> <a href="https://publications.waset.org/abstracts/50327/the-effects-of-red-onion-extract-allium-ascalonicum-l-in-the-pulmonary-histopathological-lesions-of-layer-chickens-at-47-days-old-raised-in-the-battery-cage" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50327.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">448</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">437</span> Pathomorphological Features of Lungs from Brown Hares Infected with Parasites</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mariana%20Panayotova-Pencheva">Mariana Panayotova-Pencheva</a>, <a href="https://publications.waset.org/abstracts/search?q=Anetka%20Trifonova"> Anetka Trifonova</a>, <a href="https://publications.waset.org/abstracts/search?q=Vassilena%20Dakova"> Vassilena Dakova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> 790 lungs from brown hares (<em>Lepus europeus </em>L.) from different regions of Bulgaria were investigated during the period 2009-2017.

The infections with<em> C. pisiformis </em>and <em>P. dentatum</em> were attended with small, mainly superficial changes in the lungs. Protostrongylid infections were connected with different in appearance and burden macroscopic changes. In 77.7%, they were nodular, and in the rest of cases, they diffuse. The consistency of the lesions was compact. In most of the cases, alterations were grey in colour, rarely were dark-red or marble-like. In 91.7% of these cases, they were spread on the apical parts of large lung lobes. In 36.7% middle parts of the large lung lobes, and, in 26.7% small lung lobes, were also affected.

Even with the advent of high resolution imaging cameras the image tend to have some background noise which makes the analysis complex. A study of the histological slides is done by using a nonlinear transfer function based image enhancement method. The method processes the raw, color images acquired from the biological microscope, which, in general, is associated with background noise. The images usually appearing blurred does not convey the intended information. In this regard, an enhancement method is proposed and implemented on 50 histological slides of human tissue by using nonlinear transfer function method. The histological image is converted into HSV color image. The luminance value of the image is enhanced (V component) because change in the H and S components could change the color balance between HSV components. The HSV image is divided into smaller blocks for carrying out the dynamic range compression by using a linear transformation function. Each pixel in the block is enhanced based on the contrast of the center pixel and its neighborhood. After the processing the V component, the HSV image is transformed into a colour image. The study has shown improvement of the characteristics of the image so that the significant details of the histological images were improved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HSV%20space" title="HSV space">HSV space</a>, <a href="https://publications.waset.org/abstracts/search?q=histology" title=" histology"> histology</a>, <a href="https://publications.waset.org/abstracts/search?q=enhancement" title=" enhancement"> enhancement</a>, <a href="https://publications.waset.org/abstracts/search?q=image" title=" image"> image</a> </p> <a href="https://publications.waset.org/abstracts/12167/image-enhancement-of-histological-slides-by-using-nonlinear-transfer-function" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12167.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">329</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">435</span> Pressure Losses on Realistic Geometry of Tracheobronchial Tree</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michaela%20Chovancova">Michaela Chovancova</a>, <a href="https://publications.waset.org/abstracts/search?q=Jakub%20Elcner"> Jakub Elcner</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Real bronchial tree is very complicated piping system. Analysis of flow and pressure losses in this system is very difficult. Due to the complex geometry and the very small size in the lower generations is examination by CFD possible only in the central part of bronchial tree. For specify the pressure losses of lower generations is necessary to provide a mathematical equation. Determination of mathematical formulas for calculating the pressure losses in the real lungs is due to its complexity and diversity lengthy and inefficient process. For these calculations is necessary the lungs to slightly simplify (same cross-section over the length of individual generation) or use one of the models of lungs. The simplification could cause deviations from real values. The article compares the values of pressure losses obtained from CFD simulation of air flow in the central part of the real bronchial tree with the values calculated in a slightly simplified real lungs by using a mathematical relationship derived from the Bernoulli equation and continuity equation. Then, evaluate the desirability of using this formula to determine the pressure loss across the bronchial tree. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pressure%20gradient" title="pressure gradient">pressure gradient</a>, <a href="https://publications.waset.org/abstracts/search?q=airways%20resistance" title=" airways resistance"> airways resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=real%20geometry%20of%20bronchial%20tree" title=" real geometry of bronchial tree"> real geometry of bronchial tree</a>, <a href="https://publications.waset.org/abstracts/search?q=breathing" title=" breathing"> breathing</a> </p> <a href="https://publications.waset.org/abstracts/27498/pressure-losses-on-realistic-geometry-of-tracheobronchial-tree" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/27498.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">322</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">434</span> Cadaveric Study of Lung Anatomy: A Surgical Overview</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arthi%20Ganapathy">Arthi Ganapathy</a>, <a href="https://publications.waset.org/abstracts/search?q=Rati%20Tandon"> Rati Tandon</a>, <a href="https://publications.waset.org/abstracts/search?q=Saroj%20Kaler"> Saroj Kaler</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: A thorough knowledge of variations in lung anatomy is of prime significance during surgical procedures like lobectomy, pneumonectomy, and segmentectomy of lungs. The arrangement of structures in the lung hilum act as a guide in performing such procedures. The normal pattern of arrangement of hilar structures in the right lung is eparterial bronchus, pulmonary artery, hyparterial bronchus and pulmonary veins from above downwards. In the left lung, it is pulmonary artery, principal bronchus and pulmonary vein from above downwards. The arrangement of hilar structures from anterior to posterior in both the lungs is pulmonary vein, pulmonary artery, and principal bronchus. The bronchial arteries are very small and usually the posterior most structures in the hilum of lungs. Aim: The present study aims at reporting the variations in hilar anatomy (arrangement and number) of lungs. Methodology: 75 adult formalin fixed cadaveric lungs from the department of Anatomy AIIMS New Delhi were observed for variations in the lobar anatomy. Arrangement of pulmonary hilar structures was meticulously observed, and any deviation in the pattern of presentation was recorded. Results: Among the 75 adult lung specimens observed 36 specimens were of right lung and the rest of left lung. Seven right lung specimens showed only 2 lobes with an oblique fissure dividing them and one left lung showed 3 lobes. The normal pattern of arrangement of hilar structures was seen in 22 right lungs and 23 left lungs. Rest of the lung specimens (14 right and 16 left) showed a varied pattern of arrangement of hilar structures. Some of them showed alterations in the sequence of arrangement of pulmonary artery, pulmonary veins, bronchus, and others in the number of these structures. Conclusion: Alterations in the pattern of arrangement of structures in the lung hilum are quite frequent. A compromise in knowledge of such variations will result in inadvertent complications like intraoperative bleeding during surgical procedures. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=fissures" title="fissures">fissures</a>, <a href="https://publications.waset.org/abstracts/search?q=hilum" title=" hilum"> hilum</a>, <a href="https://publications.waset.org/abstracts/search?q=lobes" title=" lobes"> lobes</a>, <a href="https://publications.waset.org/abstracts/search?q=pulmonary" title=" pulmonary"> pulmonary</a> </p> <a href="https://publications.waset.org/abstracts/77925/cadaveric-study-of-lung-anatomy-a-surgical-overview" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/77925.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">224</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">433</span> The Pressure Losses in the Model of Human Lungs</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Michaela%20Chovancova">Michaela Chovancova</a>, <a href="https://publications.waset.org/abstracts/search?q=Pavel%20Niedoba"> Pavel Niedoba</a> </p> <p class="card-text"><strong>Abstract:</strong></p> For the treatment of acute and chronic lung diseases it is preferred to deliver medicaments by inhalation. The drug is delivered directly to tracheobronchial tree. This way allows the given medicament to get directly into the place of action and it makes rapid onset of action and maximum efficiency. The transport of aerosol particles in the particular part of the lung is influenced by their size, anatomy of the lungs, breathing pattern and airway resistance. This article deals with calculation of airway resistance in the lung model of Horsfield. It solves the problem of determination of the pressure losses in bifurcation and thus defines the pressure drop at a given location in the bronchial tree. The obtained data will be used as boundary conditions for transport of aerosol particles in a central part of bronchial tree realized by Computational Fluid Dynamics (CFD) approach. The results obtained from CFD simulation will allow us to provide information on the required particle size and optimal inhalation technique for particle transport into particular part of the lung. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20lungs" title="human lungs">human lungs</a>, <a href="https://publications.waset.org/abstracts/search?q=bronchial%20tree" title=" bronchial tree"> bronchial tree</a>, <a href="https://publications.waset.org/abstracts/search?q=pressure%20losses" title=" pressure losses"> pressure losses</a>, <a href="https://publications.waset.org/abstracts/search?q=airways%20resistance" title=" airways resistance"> airways resistance</a>, <a href="https://publications.waset.org/abstracts/search?q=flow" title=" flow"> flow</a>, <a href="https://publications.waset.org/abstracts/search?q=breathing" title=" breathing "> breathing </a> </p> <a href="https://publications.waset.org/abstracts/19141/the-pressure-losses-in-the-model-of-human-lungs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19141.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">356</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">432</span> Treatment of Histopathological Symptoms in N-Nitrosopyrrolidine Induced Changes in Lung Tissue by Isolated Flavonoid from Indigofera tinctoria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aastha%20Agarwal">Aastha Agarwal</a>, <a href="https://publications.waset.org/abstracts/search?q=Veena%20Sharma"> Veena Sharma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> N-nitrosopyrollidine or NPYR is a tobacco-specific nitrosamine which upon intoxicated causes abnormal production of Reactive Oxygen Species disrupt the endogenous antioxidant system. The study was designed to evaluate the histological changes in lung tissue of Mus musculus in NPYR administered lungs and effect of isolated flavonoid 3,6-dihydroxy-(3’,4’,7’-trimethoxyphenyl)-chromen-4-one-7-glucoside (ITC) from experimental plant Indigofera tinctorial. Post treatment with isolated compound significantly restored the abnormal symptoms and changes in pulmonary tissue. Transverse section of mouse lung in control animals appeared as a thin lace. Histologically, most of the lung was arranged as alveoli which were thin walled structures made up of single layered squamous epithelial cells. In the transverse section of lung at 100 X will clearly show the component of alveoli, surround by a thin layer of connective tissue and blood vessels. Smaller bronchioles were lined by cuboidal epithelial cells while larger bronchioles were lined by ciliated columnar epithelium layer while in NPYR intoxicated lungs signs of vast pulmonary damages and carcinogenesis as alveolar damage, necrosis, DADs or defused alveolar damages hyperplasia, metaplasia, dysplasia and next stage of carcinogenesis were revealed. Treatment with ITC showed the significant positive changes in the lung tissue due to the side hydroxyl and methoxy groups in its structure which help in combating oxidative injuries and give protection from the free radicals generated during the metabolism of NPYR in body. Thus, histopathological analysis confirms the development of the cancerous conditions in the lung tissue in mice model and the protective effects of ITC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flavonoid" title="flavonoid">flavonoid</a>, <a href="https://publications.waset.org/abstracts/search?q=histopathology" title=" histopathology"> histopathology</a>, <a href="https://publications.waset.org/abstracts/search?q=Indigofera%20tinctoria" title=" Indigofera tinctoria"> Indigofera tinctoria</a>, <a href="https://publications.waset.org/abstracts/search?q=lung" title=" lung"> lung</a> </p> <a href="https://publications.waset.org/abstracts/72965/treatment-of-histopathological-symptoms-in-n-nitrosopyrrolidine-induced-changes-in-lung-tissue-by-isolated-flavonoid-from-indigofera-tinctoria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72965.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">296</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">431</span> Ultrastructural Changes Occur in Mice Lungs After Cessation to Exposure of Incense Smoke</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samar%20Rabah">Samar Rabah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Incense woods are special kind of trees called Agarwood, which characterized by good smelling odors and many medical benefits. Incense smoke is heavily used in Saudi Arabia although comprehensive studies of its effects on health are limited. The present study demonstrated lung ultrastructure changes of mice after exposure and cessation to Incense smoke. Eighty mice are divided equally into four groups, three groups are exposed to different concentrations of Incense smoke (2, 4 and 6 gm) for three months, while the fourth group is control one. At the end of each month, lungs of five animals from each group are gathered, while the last five animals from each group are kept for another 60 days without exposure to the Incense smoke to allow for recovery. Results: Transmission electron microscope investigations of all exposed groups showed hypertrophy and hyperplasia in Clara Cells and some an enlargement of the macrophage to the point that it fills a large part of the alveolar lumen. Scanning electron microscope marks presence of mucus materials attached to the epithelial bronchioles. After prevention of exposure to the Incense smoke for 60 days, necrosis and degeneration in some cells of epithelial bronchioles, fibrosis of peribronchial, thickening in alveolar walls and aggregation of lymphoid cells were demonstrated. Conclusion: Based on the above findings and other related studies (not published), we conclude that exposure to Incense smoke causes harmful effects due to sever changes in pulmonary ultrastructure, such effects do not disappear even when Incense smoke inhalation was stopped. Therefore, we recommend that Incense smoke should use only in open places to reduce its harms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Incense%20smoke" title="Incense smoke">Incense smoke</a>, <a href="https://publications.waset.org/abstracts/search?q=lungs" title=" lungs"> lungs</a>, <a href="https://publications.waset.org/abstracts/search?q=ultrastructure%20of%20lungs" title=" ultrastructure of lungs"> ultrastructure of lungs</a>, <a href="https://publications.waset.org/abstracts/search?q=Agarwood" title=" Agarwood"> Agarwood</a> </p> <a href="https://publications.waset.org/abstracts/26850/ultrastructural-changes-occur-in-mice-lungs-after-cessation-to-exposure-of-incense-smoke" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/26850.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">413</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">430</span> Effect of Omeprazole on the Renal Cortex of Adult Male Albino Rats and the Possible Protective Role of Ginger: Histological and Immunohistochemical study</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nashwa%20A.%20Mohamed">Nashwa A. Mohamed</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: Omeprazole is a proton pump inhibitor used commonly in the treatment of acid-peptic disorders. Although omeprazole is generally well tolerated, serious adverse effects such as renal failure have been reported. Ginger is an antioxidant that could play a protective role in models of experimentally induced nephropathies. Aim of the work: The aim of this work was to study the possible histological changes induced by omeprazole on renal cortex and evaluate the possible protective effect of ginger on omeprazole-induced renal damage in adult male albino rats. Materials and methods: Twenty-four adult male albino rats divided into four groups (six rats each) were used in this study. Group I served as the control group. Rats of group II received only an aqueous extract of ginger daily for 3 months through a gastric tube. Rats of group III were received omeprazole orally through a gastric tube for 3 months. Rats of group IV were given both ginger and omeprazole at the same doses and through the same routes as the previous two groups. At the end of the experiment, the rats were sacrificed. Renal tissue samples were processed for light, immunohistochemical and electron microscopic examination. The obtained results were analysed morphometrically and statistically. Results: Omeprazole caused several histological changes in the form of loss of normal appearance of renal cortex with degenerative changes in the renal corpuscle and tubules. Cellular infilteration was also observed. The filteration barrier was markedly affected. Ginger ameliorated the omeprazole-induced histological changes. Conclusion: Omeprazole induced injurious effects on renal cortex. Coadministration of ginger can ameliorate the histological changes induced by omeprazole. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ginger" title="ginger">ginger</a>, <a href="https://publications.waset.org/abstracts/search?q=kidney" title=" kidney"> kidney</a>, <a href="https://publications.waset.org/abstracts/search?q=omeprazole" title=" omeprazole"> omeprazole</a>, <a href="https://publications.waset.org/abstracts/search?q=rat" title=" rat"> rat</a> </p> <a href="https://publications.waset.org/abstracts/29467/effect-of-omeprazole-on-the-renal-cortex-of-adult-male-albino-rats-and-the-possible-protective-role-of-ginger-histological-and-immunohistochemical-study" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29467.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">429</span> The Colorectal Cancer in Patients of Eastern Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Tebibel">S.

Colorectal cancer, constituting increasingly a major public health problem, is the most common form of cancer after breast and Neck-womb cancer at the woman and prostate cancer at the man. Our work is based on a retrospective study to determine the cases of colorectal cancer through eastern Algeria. Our goal is to carry out an epidemiological, histological and immune- histochemical study to investigate different techniques for the diagnosis of colorectal cancer and their interests and specific in detecting the disease. The study includes 110 patients (aged between 20 to 87 years) with colorectal cancer where the inclusions and exclusions criteria were established. In our study, colorectal cancer, expresses a male predominance, with a sex ratio of 1, 99 and the most affected age group is between 50 and 59 years. We noted that the colon cancer rate is higher than rectal cancer rate, whose frequencies are respectively 60,91 % and 39,09 %. In the series of colon cancer, the ADK lieberkunien is histological the most represented type, or 85,07 % of all cases. In contrast, the proportion of ADK mucinous (colloid mucous) is only 1,49% only. Well-differentiated ADKS, are very significant in our series, they represent 83,58 % of cases. Adenocarcinoma moderately and poorly differentiated, whose proportions are respectively 2,99 % and 0.05 %. For histological varieties of rectal ADK, we see in our workforce that ADK lieberkunien represent the most common histological form, or 76,74%, while the mucosal colloid is 13,95 %. Research of the mutation on the gene encoding K-ras, a major step in the targeted therapy of colorectal cancers, is underway in our study. Colorectal cancer is the subject of much promising research concern: the evaluation of new therapies (antiangiogenic monoclonal antibodies), the search for predictors of sensitivity to chemotherapy and new prognostic markers using techniques of molecular biology and proteomics. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adenocarcinoma" title="adenocarcinoma">adenocarcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=age" title=" age"> age</a>, <a href="https://publications.waset.org/abstracts/search?q=colorectal%20cancer" title=" colorectal cancer"> colorectal cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=epidemiology" title=" epidemiology"> epidemiology</a>, <a href="https://publications.waset.org/abstracts/search?q=histological%20section" title=" histological section"> histological section</a>, <a href="https://publications.waset.org/abstracts/search?q=sex" title=" sex"> sex</a> </p> <a href="https://publications.waset.org/abstracts/42726/the-colorectal-cancer-in-patients-of-eastern-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/42726.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">344</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">428</span> Pathomorphological Markers of the Explosive Wave Action on Human Brain</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sergey%20Kozlov">Sergey Kozlov</a>, <a href="https://publications.waset.org/abstracts/search?q=Juliya%20Kozlova"> Juliya Kozlova</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: The increased attention of researchers to an explosive trauma around the world is associated with a constant renewal of military weapons and a significant increase in terrorist activities using explosive devices. Explosive wave is a well known damaging factor of explosion. The most sensitive to the action of explosive wave in the human body are the head brain, lungs, intestines, urine bladder. The severity of damage to these organs depends on the distance from the explosion epicenter to the object, the power of the explosion, presence of barriers, parameters of the body position, and the presence of protective clothing. One of the places where a shock wave acts, in human tissues and organs, is the vascular endothelial barrier, which suffers the greatest damage in the head brain and lungs. The objective of the study was to determine the pathomorphological changes of the head brain followed the action of explosive wave. Materials and methods of research: To achieve the purpose of the study, there have been studied 6 male corpses delivered to the morgue of Municipal Institution "Dnipropetrovsk regional forensic bureau" during 2014-2016 years. The cause of death of those killed was a military explosive injury. After a visual external assessment of the head brain, for histological study there was conducted the 1 x 1 x 1 cm/piece sampling from different parts of the head brain, i.e. the frontal, parietal, temporal, occipital sites, and also from the cerebellum, pons, medulla oblongata, thalamus, walls of the lateral ventricles, the bottom of the 4th ventricle. Pieces of the head brain were immersed in 10% formalin solution for 24 hours. After fixing, the paraffin blocks were made from the material using the standard method. Then, using a microtome, there were made sections of 4-6 micron thickness from paraffin blocks which then were stained with hematoxylin and eosin. Microscopic analysis was performed using a light microscope with x4, x10, x40 lenses. Results of the study: According to the results of our study, injuries of the head brain were divided into macroscopic and microscopic. Macroscopic injuries were marked according to the results of visual assessment of haemorrhages under the membranes and into the substance, their nature, and localisation, areas of softening. In the microscopic study, our attention was drawn to both vascular changes and those of neurons and glial cells. Microscopic qualitative analysis of histological sections of different parts of the head brain revealed a number of structural changes both at the cellular and tissue levels. Typical changes in most of the studied areas of the head brain included damages of the vascular system. The most characteristic microscopic sign was the separation of vascular walls from neuroglia with the formation of perivascular space. Along with this sign, wall fragmentation of these vessels, haemolysis of erythrocytes, formation of haemorrhages in the newly formed perivascular spaces were found. In addition to damages of the cerebrovascular system, destruction of the neurons, presence of oedema of the brain tissue were observed in the histological sections of the brain. On some sections, the head brain had a heterogeneous step-like or wave-like nature. Conclusions: The pathomorphological microscopic changes in the brain, identified in the study on the died of explosive traumas, can be used for diagnostic purposes in conjunction with other characteristic signs of explosive trauma in forensic and pathological studies. The complex of microscopic signs in the head brain, i.e. separation of blood vessel walls from neuroglia with the perivascular space formation, fragmentation of walls of these blood vessels, erythrocyte haemolysis, formation of haemorrhages in the newly formed perivascular spaces is the direct indication of explosive wave action. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=blast%20wave" title="blast wave">blast wave</a>, <a href="https://publications.waset.org/abstracts/search?q=neurotrauma" title=" neurotrauma"> neurotrauma</a>, <a href="https://publications.waset.org/abstracts/search?q=human" title=" human"> human</a>, <a href="https://publications.waset.org/abstracts/search?q=brain" title=" brain"> brain</a> </p> <a href="https://publications.waset.org/abstracts/78411/pathomorphological-markers-of-the-explosive-wave-action-on-human-brain" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/78411.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">192</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">427</span> Histological Changes in the Culex pipiens Mosquito Larvae Treated by the Entomopathogenic Fungus Beauveria bassiana</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fatma%20Sahir-%20Halouane">Fatma Sahir- Halouane</a>, <a href="https://publications.waset.org/abstracts/search?q=Sonia%20Hamid"> Sonia Hamid</a>, <a href="https://publications.waset.org/abstracts/search?q=Farida%20Tihar-Benzina"> Farida Tihar-Benzina</a>, <a href="https://publications.waset.org/abstracts/search?q=Fatiha%20Bouhlali"> Fatiha Bouhlali</a>, <a href="https://publications.waset.org/abstracts/search?q=Souad%20Lourchane"> Souad Lourchane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Culicidae are biting insects, the most harmful to people, they are almost all bloodsuckers, and they are responsible of the spread of many important diseases such as malaria, yellow fever, and elephantiasis. Entomopathogenic microorganisms occupy an important place among the alternative methods of fighting against pests insect. The fungus Beauveria bassiana is an entomopathogenic agent naturally present in the ecosystems. It offers a very interesting potential for controlling populations of mosquitoes. This study aimed to show the histological changes that occured in Culex pipiens larvae infected with Beauveria bassiana. The 4th instar larvae were infected with B. bassiana in 10-7 spore/ml dilution, the histological section was studied showing that the fungi infected all the body parts specially Cuticle, Epiderms, fat bodies and midgut. After then the insect have a white appearance and covered with a thick coat of hyphea. The obtained results show that the application of Beauveria bassiana on cuticle of the fourth stage larvae of Culex pipiens was dependent of an apparent disturbance on the structure of the cuticle or there has been the degeneration of its different parts, infection of the fungus does not stop at the body walls. Therefore, it affects even the Adipose tissue, epidermal cells and intestine. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Culex%20pipiens" title="Culex pipiens">Culex pipiens</a>, <a href="https://publications.waset.org/abstracts/search?q=Beauveria%20bassiana" title=" Beauveria bassiana"> Beauveria bassiana</a>, <a href="https://publications.waset.org/abstracts/search?q=histological%20changes" title=" histological changes"> histological changes</a>, <a href="https://publications.waset.org/abstracts/search?q=cuticle" title=" cuticle"> cuticle</a>, <a href="https://publications.waset.org/abstracts/search?q=intestine%20and%20adipose%20tissue" title=" intestine and adipose tissue "> intestine and adipose tissue </a> </p> <a href="https://publications.waset.org/abstracts/12650/histological-changes-in-the-culex-pipiens-mosquito-larvae-treated-by-the-entomopathogenic-fungus-beauveria-bassiana" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12650.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">281</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">426</span> Automatic Segmentation of Lung Pleura Based On Curvature Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sasidhar%20B.">Sasidhar B.</a>, <a href="https://publications.waset.org/abstracts/search?q=Bhaskar%20Rao%20N."> Bhaskar Rao N.</a>, <a href="https://publications.waset.org/abstracts/search?q=Ramesh%20Babu%20D.%20R."> Ramesh Babu D.

Breast cancer shows a unique spread pattern, often affecting bone, liver, lung, and brain. Breast cancer can be categorized into various subtypes according to gene expression patterns, and these subtypes exhibit specific preferences for organs where metastasis occurs. Breast tumors with luminal characteristics have a preference for spreading to the bone, whereas basal-like breast cancer (BLBC) shows a tendency to metastasize to the lungs. Still, the mechanisms behind this particular pattern of metastasis in organs have yet to be fully understood. In this evaluation, we will outline the latest progress in molecular signaling pathways and treatment methods for breast cancer lung metastasis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lung%20cancer" title="lung cancer">lung cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20cancer" title=" liver cancer"> liver cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=diagnosis" title=" diagnosis"> diagnosis</a>, <a href="https://publications.waset.org/abstracts/search?q=BLBC" title=" BLBC"> BLBC</a>, <a href="https://publications.waset.org/abstracts/search?q=metastasis" title=" metastasis"> metastasis</a> </p> <a href="https://publications.waset.org/abstracts/185132/metastasis-of-breast-cancer-to-the-lungs-implications-of-molecular-biology-and-treatment-options" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185132.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">48</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">424</span> Excessive Recruitment of Neutrophils and Elastase Release in Emphysema and COPD; Effect of Natural Protease Inhibitors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rachid%20Kacem">Rachid Kacem</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Excessive recruitment of Neutrophils into the lungs is a hallmark of several chronic inflammatory disorders such as emphysema and COPD. The resulting of this recruitment is the pathogenesis of lungs which is characterized by an imbalance between leukocyte serine proteinases mainly neutrophil elastase and the physiological inhibitors. The development of emphysema and remodeling of airway tissue occurred when neutrophil migrate into the lungs with more release of elastase and other proteolytic enzymes. Many reports have demonstrated that the extracts from medicinal plants such as Nigella sativa (L.) seeds extracts have anti-elastase activity; this is mainly due to the enrichment of the extracts with many bioactive molecules mainly phenolic compounds. Neutrophil serine proteases including human neutrophil elastase are involved in many inflammatory diseases, such as chronic obstructive pulmonary disease and emphysema. Since the current therapies for these diseases are inadequate and have numerous adverse effects, there is an acute need of potential alternative therapies. The natural protease inhibitors have received increasing attention as useful tools for potential utilization in pharmacology. This work is elucidating the most important natural phenolic substances that have been reported recently for their effectiveness as natural anti-elastase molecules, and hence, to the possibility of their use in the field of pharmaceuticals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=medicinal%20plants" title="medicinal plants">medicinal plants</a>, <a href="https://publications.waset.org/abstracts/search?q=phenols" title=" phenols"> phenols</a>, <a href="https://publications.waset.org/abstracts/search?q=elastase" title=" elastase"> elastase</a>, <a href="https://publications.waset.org/abstracts/search?q=anti-elastase" title=" anti-elastase"> anti-elastase</a>, <a href="https://publications.waset.org/abstracts/search?q=chronic%20obstructive%20pulmonary%20disease" title=" chronic obstructive pulmonary disease"> chronic obstructive pulmonary disease</a>, <a href="https://publications.waset.org/abstracts/search?q=COPD" title=" COPD"> COPD</a>, <a href="https://publications.waset.org/abstracts/search?q=emphysema" title=" emphysema"> emphysema</a> </p> <a href="https://publications.waset.org/abstracts/32920/excessive-recruitment-of-neutrophils-and-elastase-release-in-emphysema-and-copd-effect-of-natural-protease-inhibitors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32920.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">417</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">423</span> Physiochemical and Histological Study on the Effect of the Hibernation on the Liver of Uromastyx acanthinura (Bell, 1825)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Youssef.%20K.%20A.%20Abdalhafid">Youssef.

Juveniles were fed with diets containing 0, 10 or 20% of lyophilized bovine colostrum (LBC) inclusion for either 30 or 60 days. For the histological study, the intestine was divided into three segments, S1, S2 and posterior intestine. In the S1 segment, interaction between treatment and period was observed in the number of goblet cells containing sialomucin, effect of treatment in the total number of goblet cells and effect of period in the number of goblet cells containing sulphomucins (P<0.05). In the S2 segment, effect of period was observed in the number of goblet cells containing acid, neutral and total mucins, sialomucins and Vv (P<0.05). In the posterior intestine, effect of period was observed in the thickness of muscle layer and number of goblet cells containing sialomucins and sulphomucins (P<0.05). Considering the aspects studied, the presence of lyophilized bovine colostrum in the diet did not significantly influence the enteric histological characteristics of juvenile dourado during the period of the study. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=carnivorous%20fish" title="carnivorous fish">carnivorous fish</a>, <a href="https://publications.waset.org/abstracts/search?q=goblet%20cells" title=" goblet cells"> goblet cells</a>, <a href="https://publications.waset.org/abstracts/search?q=mucins" title=" mucins"> mucins</a>, <a href="https://publications.waset.org/abstracts/search?q=teleost" title=" teleost"> teleost</a> </p> <a href="https://publications.waset.org/abstracts/9976/intestinal-epithelium-of-juvenile-dourado-salminus-brasiliensis-fed-with-bovine-colostrum" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/9976.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">572</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">421</span> The Effect of Size and Tumor Depth on Histological Clearance Margins of Basal Cell Carcinomas</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Martin%20Van">Martin Van</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohammed%20Javed"> Mohammed Javed</a>, <a href="https://publications.waset.org/abstracts/search?q=Sarah%20Hemington-Gorse"> Sarah Hemington-Gorse</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim: Our aim was to determine the effect of size and tumor depth of basal cell carcinomas (BCCs) on surgical margin clearance. Methods: A retrospective study was conducted at the Welsh Centre for Burns and Plastic Surgery (WCBPS), Morriston Hospital between 1 Jan 2016 – 31 July 2016. Only patients with confirmed BCC on histopathological analysis were included. Patient data including anatomical region treated, lesion size, histopathological clearance margins and histological sub-types were recorded. An independent T-test was performed determine statistical significance. Results: A total of 228 BCCs were excised in 160 patients. Eleven lesions (4.8%) were incompletely excised. The nose area had the highest rate of incomplete excision. The mean diameter of incompletely excised lesions was 11.4mm vs 11.5mm in completely excised lesions (p=0.959) and the mean histological depth of incompletely excised lesions was 4.1mm vs. 2.5mm for completely excised BCCs (p < 0.05). Conclusions: BCC tumor depth of > 4.1 mm was associated with high rate of incomplete margin clearance. Hence, in prospective patients, a BCC tumor depth (>4 mm) on tissue biopsy should alert the surgeon of potentially higher risk of incomplete excision of lesion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=basal%20cell%20carcinoma" title="basal cell carcinoma">basal cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=excision%20margins" title=" excision margins"> excision margins</a>, <a href="https://publications.waset.org/abstracts/search?q=plastic%20surgery" title=" plastic surgery"> plastic surgery</a>, <a href="https://publications.waset.org/abstracts/search?q=treatment" title=" treatment"> treatment</a> </p> <a href="https://publications.waset.org/abstracts/68917/the-effect-of-size-and-tumor-depth-on-histological-clearance-margins-of-basal-cell-carcinomas" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/68917.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">420</span> In Vivo Evaluation of the Therapeutic Effect on Intestinal Disorders by Thermophilic Streptococcus Isolated from Camel Milk</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20T.%20%20Laiche">A.

As a prerequisite step of clinical trials, 68Ga- labelled starch based microparticles (SBMP) were analysed for their in-vivo behavior in small animals. The purpose of the presented work includes the ex-vivo biodistribution studies of 68Ga-SBMP in order to assess the activity uptake in target organs with respect to time, excretion pathways of the radiopharmaceutical, %ID/g in major organs, T/NT ratios, in-vivo stability of the radiotracer and subsequently the microparticles in the target organs. Radiolabelling of starch based microparticles was performed by incubating it with 68Ga generator eluate (430±26 MBq) at room temperature and pressure without using any harsh reaction condition. For Ex-vivo biodistribution studies healthy White Wistar rats weighing between 345-460 g were injected intravenously 68Ga-SBMP 20±8 MBq, containing about 2,00,000-6,00,000 SBMP particles in a volume of 700µL. The rats were euthanized at predefined time intervals (5min, 30min, 60min and 120min) and their organ parts were cut, washed, and put in the pre-weighed tubes and measured for radioactivity counts through automatic Gamma counter. The 68Ga-SBMP produced >99% RCP just after 10-20 min incubation through a simple and robust procedure. Biodistribution of 68Ga-SBMP showed that initially just after 5 min post injection major uptake was observed in the lungs following by blood, heart, liver, kidneys, bladder, urine, spleen, stomach, small intestine, colon, skin and skeleton, thymus and at last the smallest activity was found in brain. Radioactivity counts stayed stable in lungs with gradual decrease with the passage of time, and after 2h post injection, almost half of the activity were seen in lungs. This is a sufficient time to perform PET/CT lungs scanning in humans while activity in the liver, spleen, gut and urinary system decreased with time. The results showed that urinary system is the excretion pathways instead of hepatobiliary excretion. There was a high value of T/NT ratios which suggest fine tune images for PET/CT lung perfusion studies henceforth further pre-clinical studies and then clinical trials should be planned in order to utilize this potential lung perfusion agent. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=starch%20based%20microparticles" title="starch based microparticles">starch based microparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=gallium-68" title=" gallium-68"> gallium-68</a>, <a href="https://publications.waset.org/abstracts/search?q=biodistribution" title=" biodistribution"> biodistribution</a>, <a href="https://publications.waset.org/abstracts/search?q=target%20organs" title=" target organs"> target organs</a>, <a href="https://publications.waset.org/abstracts/search?q=excretion%20pathways" title=" excretion pathways"> excretion pathways</a> </p> <a href="https://publications.waset.org/abstracts/128551/ex-vivo-bio-distribution-studies-of-a-potential-lung-perfusion-agent" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/128551.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">173</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">418</span> Granulomatous Mycoses Fungoides: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Girum%20Tedla%20Assefa">Girum Tedla Assefa</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Granulomatous mycosis fungoides is an extremely rare type of cutaneous T-cell lymphoma (<55 cases reported worldwide). Case report: A 36-year-old female presented with soft tissue atrophy of right lower limb (dermis + hypodermis) of 22 years and plaques over trunk of 3 years duration. Histological examination of a biopsy taken from the atrophied tissue showed a granulomatous reaction with epidermotropic atypical lymphocytes. However, in other areas there were only ﬁndings of conventional MF without granuloma. Conclusion: The diagnosis of a granulomatous mycosis fungoides depends exclusively on the histological demonstration of granulomas. Distinct clinical characteristics are not present. This case highlights the importance of thorough investigation of lipoatrophic skin changes in the adult to exclude underlying causes, including MF. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cutaneous%20lymphoma" title="cutaneous lymphoma">cutaneous lymphoma</a>, <a href="https://publications.waset.org/abstracts/search?q=granulomatous%20skin%20lymphoma" title=" granulomatous skin lymphoma"> granulomatous skin lymphoma</a>, <a href="https://publications.waset.org/abstracts/search?q=mycoses%20fungoides" title=" mycoses fungoides"> mycoses fungoides</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20atrophy" title=" skin atrophy"> skin atrophy</a> </p> <a href="https://publications.waset.org/abstracts/34215/granulomatous-mycoses-fungoides-a-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/34215.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">371</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">417</span> Prerequisites for the Acquisition of Mammalian Pathogenicity by Influenza A Virus with a Prototypic Avian PB2 Gene</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chung-Young%20Lee">Chung-Young Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Se-Hee%20Ahn"> Se-Hee Ahn</a>, <a href="https://publications.waset.org/abstracts/search?q=Ilhwan%20Kim"> Ilhwan Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Du-Min%20Go"> Du-Min Go</a>, <a href="https://publications.waset.org/abstracts/search?q=Dae-Yong%20Kim"> Dae-Yong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Jun-Gu%20Choi"> Jun-Gu Choi</a>, <a href="https://publications.waset.org/abstracts/search?q=Youn-Jeong%20Lee"> Youn-Jeong Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Jae-Hong%20Kim"> Jae-Hong Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyuk-Joon%20Kwon"> Hyuk-Joon Kwon</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The polymerase of avian influenza A virus (AIV) is a heterotrimer composed of PB2, PB1 and PA. PB2 plays a role in overcoming the host barrier; however, the genetic prerequisites for avian PB2 to acquire mammalian pathogenic mutations have not been well elucidated. Here, we demonstrated that key amino acid mutations (I66M, I109V and I133V, collectively referred to as MVV) of prototypic avian PB2 increase the replication efficiency of recombinant PR8 virus carrying the mutated PB2 in both avian and mammalian hosts. The MVV mutations caused no weight loss in mice, but they did allow replication in infected lungs, and the viruses acquired fatal mammalian pathogenic mutations such as Q591R/K, E627K, or D701N in the infected lungs. The MVV mutations are located at the interfaces of the trimer and are predicted to increase the strength of this structure. Thus, gaining MVV mutations might be the first step for AIV to acquire mammalian pathogenicity. These results provide new insights into the evolution of AIV in birds and mammals. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=avian%20influenza%20A%20virus" title="avian influenza A virus">avian influenza A virus</a>, <a href="https://publications.waset.org/abstracts/search?q=prototypic%20PB2" title=" prototypic PB2"> prototypic PB2</a>, <a href="https://publications.waset.org/abstracts/search?q=polymerase%20activity" title=" polymerase activity"> polymerase activity</a>, <a href="https://publications.waset.org/abstracts/search?q=mammalian%20pathogenicity" title=" mammalian pathogenicity"> mammalian pathogenicity</a>, <a href="https://publications.waset.org/abstracts/search?q=first-step%20mutations" title=" first-step mutations"> first-step mutations</a> </p> <a href="https://publications.waset.org/abstracts/74659/prerequisites-for-the-acquisition-of-mammalian-pathogenicity-by-influenza-a-virus-with-a-prototypic-avian-pb2-gene" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74659.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">345</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">416</span> The Effect of Vitamin "E" on the Peripheral Neurotoxicity of Antimony in Adult Male Albino Rat</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pymaneh%20Bairami%20Rad">Pymaneh Bairami Rad</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The present work was planned with the aim to study the histological changes that might occur in the sciatic nerve of adult male albino rat following antimony trioxide exposure and to throw more light on the protective role of vitamin "E" on the peripheral neurotoxicity induced by this environmental toxin Sixty adult male albino rats, weighing 183 - 235 grams, were utilized in this work. The animals were divided into 3 groups; each of 20 rats: animals of group I served as control, animals of group II received antimony trioxide daily for 12 successive weeks , animals of group III received antimony trioxide and vitamin "E" daily for the same duration. Antimony trioxide was given in a daily dose of 500 mg/ kg body weight which represents 1/40 of the known LD50 and vitamin "E" was administered in a daily dose of 300 mg/kg body weight. Both antimony trioxide and vitamin "E" were given to the animals by gastric intubation. This research revealed many histological changes in the sciatic nerve, following exposure to antimony trioxide, including Wallerian degeneration in most myelinated nerve fibers with pleomorphic destruction, fragmentation, loss of normal lamination and rupture of myelin sheaths. The axoplasms of these nerve fibers were irregular, degenerated and contained myelin fragments with loss of neurofibrils. Obvious increase in endoneurium was also observed. Concomitant administration of vitamin "E" with antimony trioxide resulted in marked improvement in the histological changes observed in the sciatic nerve. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=neurotoxicity" title="neurotoxicity">neurotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=antimony" title=" antimony"> antimony</a>, <a href="https://publications.waset.org/abstracts/search?q=vitamin%20e" title=" vitamin e"> vitamin e</a>, <a href="https://publications.waset.org/abstracts/search?q=anatomy" title=" anatomy"> anatomy</a>, <a href="https://publications.waset.org/abstracts/search?q=histology" title=" histology"> histology</a> </p> <a href="https://publications.waset.org/abstracts/31796/the-effect-of-vitamin-e-on-the-peripheral-neurotoxicity-of-antimony-in-adult-male-albino-rat" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/31796.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">436</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">415</span> Pale, Soft, Exudative (PSE) Turkey Meat in a Brazilian Commercial Processing Plant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Danielle%20C.%20B.%20Honorato">Danielle C.

However, significant color changes may occur during its processing leading to the pale, soft and exudative (PSE) appearance on the surface of breast meat due to the low water holding capacity (WHC). Changes in PSE meat functional properties occur due to the myofibrils proteins denaturation caused by a rapid postmortem glycolysis resulting in a rapid pH decline while the carcass temperature is still warm. The aim of this study was to analyze the physical, chemical and histological characteristics of PSE turkey meat obtained from a Brazilian commercial processing plant. The turkey breasts samples were collected (n=64) at the processing line and classified as PSE at L* ≥ 53 value. The pH was also analyzed after L* measurement. In sequence, PSE meat samples were evaluated for WHC, cooking loss (CL), shear force (SF), myofibril fragmentation index (MFI), protein denaturation (PD) and histological evaluation. The abnormal color samples presented lower pH values, 16% lower fiber diameter, 11% lower SF and 2% lower WHC than those classified as normal. The CL, PD and MFI were, respectively, 9%, 18% and 4% higher in PSE samples. The Pearson correlation between the L* values and CL, PD and MFI was positive, while that SF and pH values presented negative correlation. Under light microscopy, a shrinking of PSE muscle cell diameter was approximately 16% shorter in relation to normal samples and an extracellular enlargement of endomysium and perimysium sheaths as the consequence of higher water contents lost as observed previously by lower WHC values. Thus, the results showed that PSE turkey breast meat presented significant changes in their physical, chemical and histological characteristics that may impair its functional properties. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=functional%20properties" title="functional properties">functional properties</a>, <a href="https://publications.waset.org/abstracts/search?q=histological%20evaluation" title=" histological evaluation"> histological evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=meat%20quality" title=" meat quality"> meat quality</a>, <a href="https://publications.waset.org/abstracts/search?q=PSE" title=" PSE"> PSE</a> </p> <a href="https://publications.waset.org/abstracts/43178/pale-soft-exudative-pse-turkey-meat-in-a-brazilian-commercial-processing-plant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43178.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">460</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">414</span> The Investigation of Effect of Alpha Lipoic Acid against Damage on Neonatal Rat Lung to Maternal Tobacco Smoke Exposure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Elif%20Erdem">Elif Erdem</a>, <a href="https://publications.waset.org/abstracts/search?q=Nalan%20Kaya"> Nalan Kaya</a>, <a href="https://publications.waset.org/abstracts/search?q=Gonca%20Ozan"> Gonca Ozan</a>, <a href="https://publications.waset.org/abstracts/search?q=Durrin%20Ozlem%20Dabak"> Durrin Ozlem Dabak</a>, <a href="https://publications.waset.org/abstracts/search?q=Enver%20Ozan"> Enver Ozan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was carried out to determine the histological and biochemical changes in the lungs of the rat pups exposed to tobacco smoke during pregnancy period and to investigate the protective effects of alpha lipoic acid, which is administered during pregnancy, on these changes. In our study, 24 six-week old Spraque-Dawley female rats weighing 160 ± 10 g were used (n:7). Rats were randomly divided into four equal groups: group I (control), group II (tobacco smoke), group III (tobacco smoke + alpha lipoic acid) and group IV (alpha lipoic acid). Rats in the group II, group III were exposed to tobacco smoke twice a day for one hour starting from eight weeks before mating and during pregnancy. In addition to tobacco smoke, 20 mg/kg of alpha lipoic acid was administered via oral gavage to the rats in the group III. Only alpha lipoic acid was administered to the rats in the group IV. Once after the delivery, all administrations were stopped. On the 7 and 21th days, the seven pups of all groups were decapitated. A portion of the lung was taken and stained with HE, PAS and Masson. In addition to immunohistochemical staining of surfactant protein A, vascular endothelial growth factor, caspase-3, TUNEL method was also used to determine apoptosis. Biochemical analyzes were performed with some part of the lung tissue specimens. In the histological evaluations performed under light microscopy, inflammatory cell increase, hemorrhagic areas, edema, interalveolar septal thickening, alveolar numbers decrease, degeneration of some bronchi and bronchial epithelium, epithelial cells that were fallen into the lumen and hyaline membrane formation were observed in tobacco smoke group. These findings were ameliorated in tobacco smoke + ALA group. Hyaline membrane formation was not detected in this group. The TUNEL positive cell numbers a significant increase was detected in the tobacco smoke group, whereas a significant decrease was detected in the tobacco smoke + ALA group. In terms of the immunoreactivity of both SP-A and VEGF, a significant decrease was observed in the tobacco smoke group, and a significant increase was observed in the tobacco smoke + ALA group. Regarding the immunoreactivity of caspase-3, there was a significant increase in the group of tobacco smoke and a significant decrease in the group of tobacco smoke + ALA. The malondialdehyde levels were determined to be significantly increased in the tobacco smoke group, and a significant decreased in the tobacco smoke + ALA. Glutathione and superoxide dismutase enzyme activities showed a significant decrease in the group of tobacco smoke and a significant increase in the tobacco smoke + ALA group. In conclusion, we suggest that the exposure to tobacco smoke during pregnancy leads to morphological, histopathological and functional changes on lung development by causing oxidative damage in lung tissues of neonatal rats and the maternal use of alpha lipoic acid can provide a protective effect on the neonatal lung development against this oxidative stress originating from tobacco smoke. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=alpha%20lipoic%20acid" title="alpha lipoic acid">alpha lipoic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=lung" title=" lung"> lung</a>, <a href="https://publications.waset.org/abstracts/search?q=neonate" title=" neonate"> neonate</a>, <a href="https://publications.waset.org/abstracts/search?q=tobacco%20smoke" title=" tobacco smoke"> tobacco smoke</a>, <a href="https://publications.waset.org/abstracts/search?q=pregnancy" title=" pregnancy"> pregnancy</a> </p> <a href="https://publications.waset.org/abstracts/74246/the-investigation-of-effect-of-alpha-lipoic-acid-against-damage-on-neonatal-rat-lung-to-maternal-tobacco-smoke-exposure" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/74246.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">211</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">413</span> Effect of Dust Rejected by Iron and Steel Complex on Roots of Bean Phaseolus vulgaris</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Labiba%20Zerari%20Bourafa">Labiba Zerari Bourafa</a>, <a href="https://publications.waset.org/abstracts/search?q=Djebar%20Mohamed%20Reda"> Djebar Mohamed Reda</a>, <a href="https://publications.waset.org/abstracts/search?q=Berrebah%20Houria"> Berrebah Houria</a>, <a href="https://publications.waset.org/abstracts/search?q=Khadri%20Sihem"> Khadri Sihem</a>, <a href="https://publications.waset.org/abstracts/search?q=Chiheb%20Linda"> Chiheb Linda</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The study of the effect of metal dust (pollutants) was performed on higher plant white beans Phaseolus vulgaris; the experience took place in cellular toxicology laboratory (in vitro culture).
