Sinapic acid (SA), as a natural phenylpropanoid, has antioxidant, anti-inflammatory, and anti-cancer properties. Materials and Methods: The purpose of the current study was to determine the protective effect of SA versus CP-induced liver toxicity. In this research, BALB/c mice were treated with SA (5 and 10 mg/kg) orally for one week, and CP (200 mg/kg) was injected on day 3 of the study. Oxidative stress markers, serum liver-specific enzymes, histopathological features, caspase-3, and nuclear factor kappa-B cells were then checked. Results: CP induced hepatotoxicity in mice and showed structural changes in liver tissue. CP significantly increased liver enzymes and lipid peroxidation and decreased glutathione. The immunoreactivity of caspase-3 and nuclear factor kappa-B cells was significantly increased. Administration of SA significantly maintained histochemical parameters and liver function enzymes in mice treated with CP. Immunohistochemical examination showed SA reduced apoptosis and inflammation. Conclusion: The data confirmed that SA with anti-apoptotic, anti-oxidative, and anti-inflammatory activities was able to preserve CP-induced liver injury in mice. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title="apoptosis">apoptosis</a>, <a href="https://publications.waset.org/abstracts/search?q=cyclophosphamide" title=" cyclophosphamide"> cyclophosphamide</a>, <a href="https://publications.waset.org/abstracts/search?q=liver%20injury" title=" liver injury"> liver injury</a>, <a href="https://publications.waset.org/abstracts/search?q=inflammation" title=" inflammation"> inflammation</a>, <a href="https://publications.waset.org/abstracts/search?q=oxidative%20stress" title=" oxidative stress"> oxidative stress</a>, <a href="https://publications.waset.org/abstracts/search?q=sinapic%20acid" title=" sinapic acid"> sinapic acid</a> </p> <a href="https://publications.waset.org/abstracts/182692/sinapic-acid-attenuation-of-cyclophosphamide-induced-liver-toxicity-in-mice-by-modulating-oxidative-stress-nf-kb-and-caspase-3" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/182692.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">56</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">18</span> Manifestation of Hybridity in Marie Jones’s "Stones in His Pockets"</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Mahjoub%20Laleh">Mahsa Mahjoub Laleh</a>, <a href="https://publications.waset.org/abstracts/search?q=Nasser%20Dasht%20Peyma"> Nasser Dasht Peyma</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper explores Marie Jones’s Stones in His Pockets in the light of the postcolonial notion of hybridity. The play is a tragicomedy about a small village in Ireland where many of the locales are extras in a Hollywood film. The actions of the play revolve around a local teenager named Sean who has been vilipended by a famous film star. The Sean character commits suicide by drowning himself with stones in his pockets. This paper explored how the attempts to gain cultural identity is manifested in Marie Jones’s play and how authority causes a change in the culture and destiny of people.

The present study aimed to investigate the effects of vitexin (5, 7, 4-trihydroxyflavone-8-glucoside), a flavonoid found in such plants as tartary buckwheat sprouts, wheat leaves phenolome, Mimosa pudica Linn and Passiflora spp, on scopolamine-induced memory impairment in rats. To achieve this goal, we assessed the effects of vitexin on memory retrieval in the presence or absence of scopolamine using a step-through passive avoidance trial. In the first part of the study, vitexin (25, 50, and 100 μM) was administered intracerebroventricularly (i.c.v.) before acquisition trials. In the second part, vitexin, at the same doses, was administered before scopolamine (10 μg, i.c.v.) and before the acquisition trials. During retention tests, vitexin (100 μM) in the absence of scopolamine significantly increased the stepthrough latencies compared to scopolamine. In addition, vitexin (100 μM) significantly reversed the shorter step-through latencies induced by scopolamine (P < 0.05). These results indicate that vitexin has a potential role in enhancing memory retrieval. A possible mechanism is modulation of cholinergic receptors; however, other mechanisms may be involved in its effects in acute exposure. <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=memory%20retrieval" title=" memory retrieval"> memory retrieval</a>, <a href="https://publications.waset.org/abstracts/search?q=passive%20avoidance" title=" passive avoidance"> passive avoidance</a>, <a href="https://publications.waset.org/abstracts/search?q=scopolamine" title=" scopolamine"> scopolamine</a>, <a href="https://publications.waset.org/abstracts/search?q=vitexin" title=" vitexin"> vitexin</a> </p> <a href="https://publications.waset.org/abstracts/6394/effects-of-vitexin-on-scopolamine-induced-memory-impairment-in-rats" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/6394.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">352</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">11</span> Impact of Variability in Delineation on PET Radiomics Features in Lung Tumors</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Falahatpour">Mahsa Falahatpour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: This study aims to explore how inter-observer variability in manual tumor segmentation impacts the reliability of radiomic features in non–small cell lung cancer (NSCLC). Methods: The study included twenty-three NSCLC tumors. Each patient had three tumor segmentations (VOL1, VOL2, VOL3) contoured on PET/CT scans by three radiation oncologists. Dice coefficients (DCS) were used to measure the segmentation variability. Radiomic features were extracted with 3D-slicer software, consisting of 66 features: first-order (n=15), second-order (GLCM, GLDM, GLRLM, and GLSZM) (n=33). The inter-observer variability of radiomic features was assessed using the intraclass correlation coefficient (ICC). An ICC > 0.8 indicates good stability. Results: The mean DSC of VOL1, VOL2, and VOL3 was 0.80 ± 0.04, 0.85 ± 0.03, and 0.76 ± 0.06, respectively. 92% of all extracted radiomic features were found to be stable (ICC > 0.8). The GLCM texture features had the highest stability (96%), followed by GLRLM features (90%) and GLSZM features (87%). The DSC was found to be highly correlated with the stability of radiomic features. Conclusion: The variability in inter-observer segmentation significantly impacts radiomics analysis, leading to a reduction in the number of appropriate radiomic features. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=PET%2FCT" title="PET/CT">PET/CT</a>, <a href="https://publications.waset.org/abstracts/search?q=radiomics" title=" radiomics"> radiomics</a>, <a href="https://publications.waset.org/abstracts/search?q=radiotherapy" title=" radiotherapy"> radiotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=segmentation" title=" segmentation"> segmentation</a>, <a href="https://publications.waset.org/abstracts/search?q=NSCLC" title=" NSCLC"> NSCLC</a> </p> <a href="https://publications.waset.org/abstracts/186981/impact-of-variability-in-delineation-on-pet-radiomics-features-in-lung-tumors" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186981.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">45</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">10</span> The Biochemical and Radiographic Evaluation of the Non-Metastatic Bone Disease in Patients with Renal Cell Carcinoma Undergoing Hemodialysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aliakbar%20Hafezi">Aliakbar Hafezi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jalal%20Taherian"> Jalal Taherian</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamshid%20Abedi"> Jamshid Abedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Elahi"> Mahsa Elahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Bones are commonly affected by renal cell carcinoma (RCC) (primarily or secondary), and this condition causes bone fragility. The aim of this study was to evaluate the diagnostic value of noninvasive methods for the diagnosis of ROD in RCC patients on hemodialysis (HD) in northern Iran. Methods: In this cross-sectional study, 50 RCC patients with ESRD referred to dialysis units in northern Iran during 2021-2024 were randomly selected and investigated.

The aim of this study was to evaluate the pathological response to NAC in patients with locally advanced breast cancer based on molecular subtypes. Method: In this retrospective cohort study, 210 female patients with breast cancer candidate for NAC referred to the radiation oncology departments in southern Iran between August 2019 and September 2024 were evaluated in terms of pathologic complete response (pCR) based on immunohistochemical molecular markers (estrogen and progesterone receptors, Her-2/neu and Ki-67), overall survival (OS) and disease-free survival (DFS). Results: The mean age of the patients was 38.22 ± 10.34 years, and 68 patients (32.4%) had a positive family history of breast cancer. The pCR rate was 17.6% (37 patients), which in the subtypes of luminal A, luminal B, Her-2/neu positive and triple negative was 7.7%, 16.9%, 26.5% and 21.05%, respectively. Patients with pCR had significantly better OS (78.4% vs. 49.1%, P = 0.014) and DFS (83.8% vs. 51.4%, P = 0.020) than patients with partial/no pathological response.

This research applied a descriptive survey that investigated a correlation between variables. The target population was 140 employees of a Drilling Fluid and Waste Management Service Company, and the sample was 123 employees who were selected randomly and encouraged to complete an electronic questionnaire which was designed based on standard questionnaires for research variables covering 62 questions. The face validity of the questionnaire was supported by an experimental test, and its content validity was approved by the thesis supervisor and consulting advisor. For the descriptive statistics frequency tables and diagrams, measures of central tendency such as mode, median, and mean and measures of variability such as variance, standards deviation, and quartile deviation were used. In the inferential statistics section, the Pearson correlation coefficient was used to verify the relationship between the variables of the research. According to the results, all of the research hypotheses were supported. According to hypothesis 1, there was a positive and significant relationship between training policy-making and employees’ psychological ownership (r=0/408, α=0/05). According to hypothesis 2, there was a positive and significant relationship between training planning and employees’ psychological ownership (r=0/446, α=0/05). According to hypothesis 3, there was a positive and significant relationship between providing the training and employees’ psychological ownership (r=0/512, α=0/05). According to hypothesis 4, there was a positive and significant relationship between training performance management and employees’ psychological ownership (r=0/462, α=0/05). According to hypothesis 5, there was a positive and significant relationship between employees’ motivation and psychological ownership (r=0/694, α=0/05). Therefore, through systematic in-service training, which is in the same line with the strategic goals of an organization and is based on scientific needs analysis, design, implementation, and evaluation, it is possible to improve employees’ sense of psychological ownership toward an organization. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=in-service%20training" title="in-service training">in-service training</a>, <a href="https://publications.waset.org/abstracts/search?q=motivation" title=" motivation"> motivation</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20behavior" title=" organizational behavior"> organizational behavior</a>, <a href="https://publications.waset.org/abstracts/search?q=psychological%20ownership" title=" psychological ownership"> psychological ownership</a> </p> <a href="https://publications.waset.org/abstracts/161593/relationship-between-in-service-training-and-employees-feeling-of-psychological-ownership" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161593.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">61</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">7</span> Protection of Steel Bars in Reinforce Concrete with Zinc Based Coverings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamed%20Rajabzadeh%20Gatabi">Hamed Rajabzadeh Gatabi</a>, <a href="https://publications.waset.org/abstracts/search?q=Soroush%20Dastgheibifard"> Soroush Dastgheibifard</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Asnafi"> Mahsa Asnafi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> There is no doubt that reinforced concrete is known as one of the most significant materials which is used in construction industry for many years. Although, some natural elements in dealing with environment can contribute to its corrosion or failure. One of which is bar or so-called reinforcement failure. So as to combat this problem, one of the oxidization prevention methods investigated was the barrier protection method implemented over the application of an organic coating, specifically fusion-bonded epoxy. In this study comparative method is prepared on two different kinds of covered bars (zinc-riches epoxy and polyamide epoxy coated bars) and also uncoated bar. With the aim of evaluate these reinforced concretes, the stickiness, toughness, thickness and corrosion performance of coatings were compared by some tools like Cu/CuSo4 electrodes, EIS and etc. Different types of concretes were exposed to the salty environment (NaCl 3.5%) and their durability was measured. As stated by the experiments in research and investigations, thick coatings (named epoxies) have acceptable stickiness and strength. Polyamide epoxy coatings stickiness to the bars was a bit better than that of zinc-rich epoxy coatings; nonetheless it was stiffer than the zinc rich epoxy coatings. Conversely, coated bars with zinc-rich epoxy showed more negative oxidization potentials, which take revenge protection of bars by zinc particles. On the whole, zinc-rich epoxy coverings is more corrosion-proof than polyamide epoxy coatings due to consuming zinc elements and some other parameters, additionally if the epoxy coatings without surface defects are applied on the rebar surface carefully, it can be said that the life of steel structures is subjected to increase dramatically. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=surface%20coating" title="surface coating">surface coating</a>, <a href="https://publications.waset.org/abstracts/search?q=epoxy%20polyamide" title=" epoxy polyamide"> epoxy polyamide</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforce%20concrete%20bars" title=" reinforce concrete bars"> reinforce concrete bars</a>, <a href="https://publications.waset.org/abstracts/search?q=salty%20environment" title=" salty environment"> salty environment</a> </p> <a href="https://publications.waset.org/abstracts/40405/protection-of-steel-bars-in-reinforce-concrete-with-zinc-based-coverings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40405.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">289</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">6</span> Flexible Furniture in Urban Open Spaces: A Tool to Achieve Social Sustainability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Ghafouri">Mahsa Ghafouri</a>, <a href="https://publications.waset.org/abstracts/search?q=Guita%20Farivarsadri"> Guita Farivarsadri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In urban open spaces, furniture plays a crucial role in meeting various needs of the users over time. Furniture consists of elements that not only can facilitate physical needs individually but also fulfill social, psychological, and cultural demands on an urban scale. Creating adjustable urban spaces and using flexible furniture can provide the possibility of using urban spaces for a wide range of uses and activities and allow the engagement of users with distinct abilities and limitations in these activities. Flexibility in urban furniture can be seen as designing a number of modular components that are movable, expandable, adjustable, and changeable to accommodate various functions. Although there is a great amount of research related to flexibility and its distinct insights into achieving spaces that can cope with changing demands, this fundamental issue is often neglected in the design of urban furniture. However, in the long term, to address changing public needs over time, it can be logical to bring this quality into the design process to make spaces that can be sustained for a long time. This study aims to first introduce diverse kinds of flexible furniture that can be designed for urban public spaces and then to realize how this flexible furniture can improve the quality of public open spaces and social interaction and make them more adaptable over time and, as a result, achieve social sustainability. This research is descriptive and is mainly based on an extensive literature review and the analysis and classification of existing examples around the world. This research tends to illustrate various kinds of approaches that can help designers create flexible furniture to enhance the sustainability and quality of urban open spaces and, in this way, act as a guide for urban designers in this respect. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=flexible%20furniture" title="flexible furniture">flexible furniture</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20design" title=" flexible design"> flexible design</a>, <a href="https://publications.waset.org/abstracts/search?q=urban%20open%20spaces" title=" urban open spaces"> urban open spaces</a>, <a href="https://publications.waset.org/abstracts/search?q=adaptability" title=" adaptability"> adaptability</a>, <a href="https://publications.waset.org/abstracts/search?q=moveability" title=" moveability"> moveability</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20sustainability" title=" social sustainability"> social sustainability</a> </p> <a href="https://publications.waset.org/abstracts/181521/flexible-furniture-in-urban-open-spaces-a-tool-to-achieve-social-sustainability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/181521.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">59</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">5</span> Nanopharmaceutical: A Comprehensive Appearance of Drug Delivery System</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Fathollahzadeh">Mahsa Fathollahzadeh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The various nanoparticles employed in drug delivery applications include micelles, liposomes, solid lipid nanoparticles, polymeric nanoparticles, functionalized nanoparticles, nanocrystals, cyclodextrins, dendrimers, and nanotubes. Micelles, composed of amphiphilic block copolymers, can encapsulate hydrophobic molecules, allowing for targeted delivery. Liposomes, vesicular structures made up of phospholipids, can encapsulate both hydrophobic and hydrophilic molecules, providing a flexible platform for delivering therapeutic agents. Solid lipid nanoparticles (SLNs) and nanostructured lipid carriers (NLCs) are designed to improve the stability and bioavailability of lipophilic drugs. Polymeric nanoparticles, such as poly(lactic-co-glycolic acid) (PLGA), are biodegradable and can be engineered to release drugs in a controlled manner. Functionalized nanoparticles, coated with targeting ligands or antibodies, can specifically target diseased cells or tissues. Nanocrystals, engineered to have specific surface properties, can enhance the solubility and bioavailability of poorly soluble drugs. Cyclodextrins, doughnut-shaped molecules with hydrophobic cavities, can be complex with hydrophobic molecules, allowing for improved solubility and bioavailability. Dendrimers, branched polymers with a central core, can be designed to deliver multiple therapeutic agents simultaneously. Nanotubes and metallic nanoparticles, such as gold nanoparticles, offer real-time tracking capabilities and can be used to detect biomolecular interactions. The use of these nanoparticles has revolutionized the field of drug delivery, enabling targeted and controlled release of therapeutic agents, reduced toxicity, and improved patient outcomes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=nanotechnology" title="nanotechnology">nanotechnology</a>, <a href="https://publications.waset.org/abstracts/search?q=nanopharmaceuticals" title=" nanopharmaceuticals"> nanopharmaceuticals</a>, <a href="https://publications.waset.org/abstracts/search?q=drug-delivery" title=" drug-delivery"> drug-delivery</a>, <a href="https://publications.waset.org/abstracts/search?q=proteins" title=" proteins"> proteins</a>, <a href="https://publications.waset.org/abstracts/search?q=ligands" title=" ligands"> ligands</a>, <a href="https://publications.waset.org/abstracts/search?q=nanoparticles" title=" nanoparticles"> nanoparticles</a>, <a href="https://publications.waset.org/abstracts/search?q=chemistry" title=" chemistry"> chemistry</a> </p> <a href="https://publications.waset.org/abstracts/186065/nanopharmaceutical-a-comprehensive-appearance-of-drug-delivery-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/186065.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">51</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">4</span> Experimental Determination of Shear Strength Properties of Lightweight Expanded Clay Aggregates Using Direct Shear and Triaxial Tests</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Shafaei%20Bajestani">Mahsa Shafaei Bajestani</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahmoud%20Yazdani"> Mahmoud Yazdani</a>, <a href="https://publications.waset.org/abstracts/search?q=Aliakbar%20Golshani"> Aliakbar Golshani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Artificial lightweight aggregates have a wide range of applications in industry and engineering. Nowadays, the usage of this material in geotechnical activities, especially as backfill in retaining walls has been growing due to the specific characteristics which make it a competent alternative to the conventional geotechnical materials. In practice, a material with lower weight but higher shear strength parameters would be ideal as backfill behind retaining walls because of the important roles that these parameters play in decreasing the overall active lateral earth pressure. In this study, two types of Light Expanded Clay Aggregates (LECA) produced in the Leca factory are investigated. LECA is made in a rotary kiln by heating natural clay at different temperatures up to 1200 °C making quasi-spherical aggregates with different sizes ranged from 0 to 25 mm. The loose bulk density of these aggregates is between 300 and 700 kN/m<sup>3</sup>. The purpose of this research is to determine the stress-strain behavior, shear strength parameters, and the energy absorption of LECA materials. Direct shear tests were conducted at five normal stresses of 25, 50, 75, 100, and 200 kPa. In addition, conventional triaxial compression tests were operated at confining pressures of 50, 100, and 200 kPa to examine stress-strain behavior. The experimental results show a high internal angle of friction and even a considerable amount of nominal cohesion despite the granular structure of LECA. These desirable properties along with the intrinsic low density of these aggregates make LECA as a very proper material in geotechnical applications. Furthermore, the results demonstrate that lightweight aggregates may have high energy absorption that is excellent alternative material in seismic isolations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=expanded%20clay" title="expanded clay">expanded clay</a>, <a href="https://publications.waset.org/abstracts/search?q=direct%20shear%20test" title=" direct shear test"> direct shear test</a>, <a href="https://publications.waset.org/abstracts/search?q=triaxial%20test" title=" triaxial test"> triaxial test</a>, <a href="https://publications.waset.org/abstracts/search?q=shear%20properties" title=" shear properties"> shear properties</a>, <a href="https://publications.waset.org/abstracts/search?q=energy%20absorption" title=" energy absorption"> energy absorption</a> </p> <a href="https://publications.waset.org/abstracts/75574/experimental-determination-of-shear-strength-properties-of-lightweight-expanded-clay-aggregates-using-direct-shear-and-triaxial-tests" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75574.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">166</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">3</span> Preoperative versus Postoperative Radiation Therapy in Patients with Soft Tissue Sarcoma of the Extremity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=AliAkbar%20Hafezi">AliAkbar Hafezi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jalal%20Taherian"> Jalal Taherian</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamshid%20Abedi"> Jamshid Abedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Elahi"> Mahsa Elahi</a>, <a href="https://publications.waset.org/abstracts/search?q=Behnam%20Kadkhodaei"> Behnam Kadkhodaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Soft tissue sarcomas (STS) are generally treated with a combination of limb preservation surgery and radiation therapy. Today, preoperative radiation therapy is considered for accurate treatment volume and smaller field size. Therefore, this study was performed to compare preoperative with postoperative radiation therapy in patients with extremity STS. Methods: In this non-randomized clinical trial, patients with localized extremity STS referred to the orthopedic clinics in Iran from 2021 to 2023 were studied. Patients were randomly divided into two groups: preoperative and postoperative radiation therapy. The two groups of patients were compared in terms of acute (wound dehiscence and infection) and late (limb edema, subcutaneous fibrosis, and joint stiffness) complications and their severity, as well as local recurrence and other one-year outcomes. Results: A total of 80 patients with localized extremity STS were evaluated in two treatment groups. The groups were matched in terms of age, sex, history of diabetes mellitus, hypertension, smoking, involved side, involved extremity, lesion location, and tumor histopathology. The acute complications of treatment in the two groups of patients did not differ significantly (P > 0.05). Of the late complications, only joint stiffness between the two groups had significant statistical differences (P < 0.001). The severity of all three late complications in the postoperative radiation therapy group was significantly higher (P < 0.05). There was no significant difference between the two groups in terms of the rate of local recurrence of other one-year outcomes (P > 0.05). Conclusion: This study showed that in patients with localized extremity STS, the two therapeutic approaches of adjuvant and neoadjuvant radiation therapy did not differ significantly in terms of local recurrence and distant metastasis during the one-year follow-up period and due to fewer late complications in preoperative radiotherapy group, this treatment approach can be a better choice than postoperative radiation therapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soft%20tissue%20sarcoma" title="soft tissue sarcoma">soft tissue sarcoma</a>, <a href="https://publications.waset.org/abstracts/search?q=extremity" title=" extremity"> extremity</a>, <a href="https://publications.waset.org/abstracts/search?q=preoperative%20radiation%20therapy" title=" preoperative radiation therapy"> preoperative radiation therapy</a>, <a href="https://publications.waset.org/abstracts/search?q=postoperative%20radiation%20therapy" title=" postoperative radiation therapy"> postoperative radiation therapy</a> </p> <a href="https://publications.waset.org/abstracts/185610/preoperative-versus-postoperative-radiation-therapy-in-patients-with-soft-tissue-sarcoma-of-the-extremity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185610.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">45</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">2</span> Preparation and Evaluation of Gelatin-Hyaluronic Acid-Polycaprolactone Membrane Containing 0.5 % Atorvastatin Loaded Nanostructured Lipid Carriers as a Nanocomposite Scaffold for Skin Tissue Engineering</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Ahmadi">Mahsa Ahmadi</a>, <a href="https://publications.waset.org/abstracts/search?q=Mehdi%20Mehdikhani-Nahrkhalaji"> Mehdi Mehdikhani-Nahrkhalaji</a>, <a href="https://publications.waset.org/abstracts/search?q=Jaleh%20Varshosaz"> Jaleh Varshosaz</a>, <a href="https://publications.waset.org/abstracts/search?q=Shadi%20Farsaei"> Shadi Farsaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Gelatin and hyaluronic acid are commonly used in skin tissue engineering scaffolds, but because of their low mechanical properties and high biodegradation rate, adding a synthetic polymer such as polycaprolactone could improve the scaffold properties. Therefore, we developed a gelatin-hyaluronic acid-polycaprolactone scaffold, containing 0.5 % atorvastatin loaded nanostructured lipid carriers (NLCs) for skin tissue engineering. The atorvastatin loaded NLCs solution was prepared by solvent evaporation method and freeze drying process. Synthesized atorvastatin loaded NLCs was added to the gelatin and hyaluronic acid solution, and a membrane was fabricated with solvent evaporation method. Thereafter it was coated by a thin layer of polycaprolactone via spine coating set. The resulting scaffolds were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) analyses. Moreover, mechanical properties, in vitro degradation in 7 days period, and in vitro drug release of scaffolds were also evaluated. SEM images showed the uniform distributed NLCs with an average size of 100 nm in the scaffold structure. Mechanical test indicated that the scaffold had a 70.08 Mpa tensile modulus which was twofold of tensile modulus of normal human skin. A Franz-cell diffusion test was performed to investigate the scaffold drug release in phosphate buffered saline (pH=7.4) medium. Results showed that 72% of atorvastatin was released during 5 days. In vitro degradation test demonstrated that the membrane was degradated approximately 97%. In conclusion, suitable physicochemical and biological properties of membrane indicated that the developed gelatin-hyaluronic acid-polycaprolactone nanocomposite scaffold containing 0.5 % atorvastatin loaded NLCs could be used as a good candidate for skin tissue engineering applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=atorvastatin" title="atorvastatin">atorvastatin</a>, <a href="https://publications.waset.org/abstracts/search?q=gelatin" title=" gelatin"> gelatin</a>, <a href="https://publications.waset.org/abstracts/search?q=hyaluronic%20acid" title=" hyaluronic acid"> hyaluronic acid</a>, <a href="https://publications.waset.org/abstracts/search?q=nano%20lipid%20carriers%20%28NLCs%29" title=" nano lipid carriers (NLCs)"> nano lipid carriers (NLCs)</a>, <a href="https://publications.waset.org/abstracts/search?q=polycaprolactone" title=" polycaprolactone"> polycaprolactone</a>, <a href="https://publications.waset.org/abstracts/search?q=skin%20tissue%20engineering" title=" skin tissue engineering"> skin tissue engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=solvent%20casting" title=" solvent casting"> solvent casting</a>, <a href="https://publications.waset.org/abstracts/search?q=solvent%20evaporation" title=" solvent evaporation"> solvent evaporation</a> </p> <a href="https://publications.waset.org/abstracts/75203/preparation-and-evaluation-of-gelatin-hyaluronic-acid-polycaprolactone-membrane-containing-05-atorvastatin-loaded-nanostructured-lipid-carriers-as-a-nanocomposite-scaffold-for-skin-tissue-engineering" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75203.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">1</span> The Preventive Effect of Metformin on Paclitaxel-Induced Peripheral Neuropathy</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=AliAkbar%20Hafezi">AliAkbar Hafezi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamshid%20Abedi"> Jamshid Abedi</a>, <a href="https://publications.waset.org/abstracts/search?q=Jalal%20Taherian"> Jalal Taherian</a>, <a href="https://publications.waset.org/abstracts/search?q=Behnam%20Kadkhodaei"> Behnam Kadkhodaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahsa%20Elahi"> Mahsa Elahi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background. Peripheral neuropathy is a common side effect of the administration of neurotoxic chemotherapy agents. This adverse effect is a major dose-limiting factor of many commonly used chemotherapy drugs. Currently, there are no Food and Drug Administration (FDA) approved medications for the prevention or treatment of chemotherapy-induced peripheral neuropathy. Therefore, this study was performed to investigate the efficacy and safety of metformin on paclitaxel-induced peripheral neuropathy (PIPN). Methods. In this randomized clinical trial, cancer patients who were candidates for chemotherapy with paclitaxel referred to the radiation oncology departments in Iran from 2022 to 2023 were studied. Patients were randomly divided into two groups; 1- Case group (n = 30) received metformin 500 mg orally twice a day after meals during chemotherapy with paclitaxel, and 2- Control group (30 people) received chemotherapy without metformin or any additional medication. Patients were visited in terms of numbness or other neurological symptoms two weeks before chemotherapy, 1-2 days before and weekly during chemotherapy, and at the end of the study. They were assessed by nerve conduction study (NCS) before intervention and one week after the end of chemotherapy. The primary outcome was the efficacy in reducing PIPN and the secondary outcome was adverse effects. Eventually, the outcomes were compared between the two groups of patients. Results. A total of 60 female cancer patients receiving chemotherapy with paclitaxel were evaluated in two groups. The groups were matched in terms of age, body mass index, fasting blood sugar, smoking, pathologic stage, and creatinine levels. The results showed that 18 patients (60.0 %) in the case group and 23 patients (76.6 %) in the control group had PIPN clinically (P = 0.267), and NCS showed 11 patients (36.6 %) in the case group and 15 patients (50.0 %) in the control group suffered from PIPN which no significant difference was observed between the two groups (P = 0.435). Diarrhea (n = 3; 10.0 %) and nausea (n = 3; 10.0 %) were the most common side effects of metformin in the case group and no serious side effects (lactic acidosis and anemia) were found in these patients. Conclusion. This study indicated that metformin did not significantly prevent PIPN in cancer patients receiving chemotherapy, although the frequency of peripheral neuropathy in the case group was lower than in the control group. The use of metformin in the patients had acceptable safety and no serious side effects were reported. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=peripheral%20neuropathy" title="peripheral neuropathy">peripheral neuropathy</a>, <a href="https://publications.waset.org/abstracts/search?q=chemotherapy" title=" chemotherapy"> chemotherapy</a>, <a href="https://publications.waset.org/abstracts/search?q=paclitaxel" title=" paclitaxel"> paclitaxel</a>, <a href="https://publications.waset.org/abstracts/search?q=metformin" title=" metformin"> metformin</a> </p> <a href="https://publications.waset.org/abstracts/185765/the-preventive-effect-of-metformin-on-paclitaxel-induced-peripheral-neuropathy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185765.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">43</span> </span> </div> </div> </div> </main> <footer> <div id="infolinks" class="pt-3 pb-2"> <div class="container"> <div style="background-color:#f5f5f5;" class="p-3"> <div class="row"> <div class="col-md-2"> <ul class="list-unstyled"> About <li><a href="https://waset.org/page/support">About Us</a></li> <li><a href="https://waset.org/page/support#legal-information">Legal</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/WASET-16th-foundational-anniversary.pdf">WASET celebrates its 16th foundational anniversary</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Account <li><a href="https://waset.org/profile">My Account</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Explore <li><a href="https://waset.org/disciplines">Disciplines</a></li> <li><a href="https://waset.org/conferences">Conferences</a></li> <li><a href="https://waset.org/conference-programs">Conference Program</a></li> <li><a href="https://waset.org/committees">Committees</a></li> <li><a href="https://publications.waset.org">Publications</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Research <li><a href="https://publications.waset.org/abstracts">Abstracts</a></li> <li><a href="https://publications.waset.org">Periodicals</a></li> <li><a href="https://publications.waset.org/archive">Archive</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Open Science <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Philosophy.pdf">Open Science Philosophy</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Science-Award.pdf">Open Science Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Open-Society-Open-Science-and-Open-Innovation.pdf">Open Innovation</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Postdoctoral-Fellowship-Award.pdf">Postdoctoral Fellowship Award</a></li> <li><a target="_blank" rel="nofollow" href="https://publications.waset.org/static/files/Scholarly-Research-Review.pdf">Scholarly Research Review</a></li> </ul> </div> <div class="col-md-2"> <ul class="list-unstyled"> Support <li><a href="https://waset.org/page/support">Support</a></li> <li><a href="https://waset.org/profile/messages/create">Contact Us</a></li> <li><a href="https://waset.org/profile/messages/create">Report Abuse</a></li> </ul> </div> </div> </div> </div> </div> <div class="container text-center"> <hr style="margin-top:0;margin-bottom:.3rem;"> <a href="https://creativecommons.org/licenses/by/4.0/" target="_blank" class="text-muted small">Creative Commons Attribution 4.0 International License</a> <div id="copy" class="mt-2">© 2024 World Academy of Science, Engineering and Technology</div> </div> </footer> <a href="javascript:" id="return-to-top"><i class="fas fa-arrow-up"></i></a> <div class="modal" id="modal-template"> <div class="modal-dialog"> <div class="modal-content"> <div class="row m-0 mt-1"> <div class="col-md-12"> <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button> </div> </div> <div class="modal-body"></div> </div> </div> </div> <script src="https://cdn.waset.org/static/plugins/jquery-3.3.1.min.js"></script> <script src="https://cdn.waset.org/static/plugins/bootstrap-4.2.1/js/bootstrap.bundle.min.js"></script> <script src="https://cdn.waset.org/static/js/site.js?v=150220211556"></script> <script> jQuery(document).ready(function() { /*jQuery.get("https://publications.waset.org/xhr/user-menu", function (response) { jQuery('#mainNavMenu').append(response); });*/ jQuery.get({ url: "https://publications.waset.org/xhr/user-menu", cache: false }).then(function(response){ jQuery('#mainNavMenu').append(response); }); }); </script> </body> </html>
