The most commonly used incision for modified radical mastectomy is the transverse Stewart incision. But this incision may have the disadvantage of causing disparity between the closure lines of superior and inferior skin flaps in mastectomy and can cause overhanging of soft tissue below and behind the axilla. The curvizigzag incision, on principle, may help in this regard and can prevent scar migration beyond the anterior axillary line. This study aims to compare the two incisions in this regard. Methods: 100 patients with cancer of breast were included in the study after satisfying inclusion and exclusion criteria. They underwent surgery at Father Muller Medical College, Mangalore, India, between November 2019 to September 2021. The patients were divided into two groups. Group A patients were subjected to modified radical mastectomy with curvizigzag incision and group B patients with transverse Stewart incision. Results: Seroma on postoperative day1, day 2 was 0% in both the groups. Seroma on postoperative day 30 was present in 14% of patients in group B. 60% of patients in group B had sag of soft tissue below and behind the axilla, and none of the patients in group A had this problem. In 64% of the patients in group B, the incision crossed the anterior axillary fold, 64% of the patients in group B had tension in the incision site while approximation of the skin flaps. Conclusion: Curvizigzag incision is statistically better with lesser complications when compared to the transverse Stewart incision for modified radical mastectomy for carcinoma breast. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=breast%20cancer" title="breast cancer">breast cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=curvizigzag%20incision" title=" curvizigzag incision"> curvizigzag incision</a>, <a href="https://publications.waset.org/abstracts/search?q=transverse%20Stewart%20incision" title=" transverse Stewart incision"> transverse Stewart incision</a>, <a href="https://publications.waset.org/abstracts/search?q=seroma" title=" seroma"> seroma</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20radical%20mastectomy" title=" modified radical mastectomy"> modified radical mastectomy</a> </p> <a href="https://publications.waset.org/abstracts/153834/comparison-of-the-curvizigzag-incision-with-transverse-stewart-incision-in-women-undergoing-modified-radical-mastectomy-for-carcinoma-breast" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/153834.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">95</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">38</span> Modeling of a Stewart Platform for Analyzing One Directional Dynamics for Spacecraft Docking Operations</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Leonardo%20Herrera">Leonardo Herrera</a>, <a href="https://publications.waset.org/abstracts/search?q=Shield%20B.%20Lin"> Shield B.

A simplified mechanical drawing was created, capturing the physical structure's main features. A simplified schematic diagram was developed into a lumped mass model from the mechanical drawing. Three differential equations were derived according to the schematic diagram. A Simulink diagram was created using MATLAB to represent the three equations. System parameters, including spring constants and masses, are derived in detail from the physical system. The model can be used for further analysis via computer simulation in predicting dynamic response in its main docking direction, i.e., up-and-down motion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=stewart%20platform" title="stewart platform">stewart platform</a>, <a href="https://publications.waset.org/abstracts/search?q=docking%20operation" title=" docking operation"> docking operation</a>, <a href="https://publications.waset.org/abstracts/search?q=spacecraft" title=" spacecraft"> spacecraft</a>, <a href="https://publications.waset.org/abstracts/search?q=spring%20constant" title=" spring constant"> spring constant</a> </p> <a href="https://publications.waset.org/abstracts/170471/modeling-of-a-stewart-platform-for-analyzing-one-directional-dynamics-for-spacecraft-docking-operations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170471.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">199</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">37</span> Coupled Analysis with Fluid and Flexible Multibody Dynamics of 6-DOF Platform with Liquid Sloshing Tank</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sung-Pill%20Kim">Sung-Pill Kim</a>, <a href="https://publications.waset.org/abstracts/search?q=Dae-Gyu%20Sung"> Dae-Gyu Sung</a>, <a href="https://publications.waset.org/abstracts/search?q=Hee-Sung%20Shin"> Hee-Sung Shin</a>, <a href="https://publications.waset.org/abstracts/search?q=Jong-Chun%20Park"> Jong-Chun Park</a> </p> <p class="card-text"><strong>Abstract:</strong></p> When a sloshing tank filled partially with liquid is excited with the motion of platform, it can be observed that the center of mass inside the tank is changed and impact loads is instantaneously applied to the wall, which causes dynamic loads additionally to the supporting links of platform. In this case, therefore, the dynamic behavior of platform associated with fluid motion should be considered in the early stage of design for safety and economics of the system. In this paper, the dynamic loads due to liquid sloshing motion in a rectangular tank which is loaded up on the upper deck of a Stewart platform are simulated using a coupled analysis of Moving Particle Simulation (MPS) and Flexible Multi-Body Dynamics (FMBD). The co-simulation is performed using two commercial softwares, Recurdyn for solving FMBD and Particleworks for analyzing fluid motion based on MPS method. For validating the present coupled system, a rectangular sloshing tank being enforced with inline sway motion by 1-DOF motion platform is assumed, and time-varied free-surface elevation and reaction force at a fixed joint are compared with experiments. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20loads" title="dynamic loads">dynamic loads</a>, <a href="https://publications.waset.org/abstracts/search?q=liquid%20sloshing%20tank" title=" liquid sloshing tank"> liquid sloshing tank</a>, <a href="https://publications.waset.org/abstracts/search?q=Stewart%20platform" title=" Stewart platform"> Stewart platform</a>, <a href="https://publications.waset.org/abstracts/search?q=moving%20particle%20semi-implicit%20%28MPS%29%20method" title=" moving particle semi-implicit (MPS) method"> moving particle semi-implicit (MPS) method</a>, <a href="https://publications.waset.org/abstracts/search?q=flexible%20multi-body%20dynamics%20%28FMBD%29" title=" flexible multi-body dynamics (FMBD)"> flexible multi-body dynamics (FMBD)</a> </p> <a href="https://publications.waset.org/abstracts/32915/coupled-analysis-with-fluid-and-flexible-multibody-dynamics-of-6-dof-platform-with-liquid-sloshing-tank" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/32915.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">705</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">36</span> Digital Interventions for Older People Experiencing Homelessness (OPEH): A Systematic Scoping Review</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Emily%20Adams">Emily Adams</a>, <a href="https://publications.waset.org/abstracts/search?q=Eddie%20Donaghy"> Eddie Donaghy</a>, <a href="https://publications.waset.org/abstracts/search?q=David%20Henderson"> David Henderson</a>, <a href="https://publications.waset.org/abstracts/search?q=Lauren%20Ng"> Lauren Ng</a>, <a href="https://publications.waset.org/abstracts/search?q=Caroline%20Sanders"> Caroline Sanders</a>, <a href="https://publications.waset.org/abstracts/search?q=Rowena%20Stewart"> Rowena Stewart</a>, <a href="https://publications.waset.org/abstracts/search?q=Maria%20Wolters"> Maria Wolters</a>, <a href="https://publications.waset.org/abstracts/search?q=Stewart%20Mercer"> Stewart Mercer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Ongoing review abstract: Older People Experiencing Homelessness (OPEH) can have mental and physical indicators of aging 10–20 years earlier than the general population and experience premature mortality due to age-related chronic conditions. Emerging literature suggests digital interventions could positively impact PEH’s well-being. However, the increased reliance on digital delivery may also perpetuate digital inequalities for socially excluded groups, including PEH. The potential triple disadvantage of being older, homeless, and digitally excluded creates a uniquely problematic situation that warrants further research. This scoping review aims to investigate and synthesise the range and type of digital interventions available to OPEH and the organisations that support OPEH. The following databases were searched on 28th July 2023: Medline, Scopus, International Bibliography of the Social Sciences (IBSS)‎, Applied Social Sciences Index & Abstracts (ASSIA)‎, Association for Computing Machinery Digital Library (ACMDL) and Policy commons.

Stewart ex Brandis galls (EOPI). EOPI was investigated for its potential antiasthmatic action using in vitro antiallergic assays mast cell degranulation and soyabean lipoxidase enzyme activit, and spasmolytic action using isolated guinea pig ileum preparation. In vivo studies included lipopolysaccharide-induced bronchial inflammation in rats and airway hyperresponsiveness in ovalbumin in sensitized guinea pigs using spirometry. Data was analysed by GraphPad Prism 5.01 and results were expressed as means ± SEM. P < 0.05 was considered to be significant. EOPI inhibits 5-lipoxidase enzyme activity, DPPH scavenging activity and erythropoietin- induced angiogenesis. It showed dose dependent anti-allergic activity by inhibiting compound 48/80 induced mast cell degranulation. The finding that essential oil induced inhibition of transient contraction of acetylcholine in calcium free medium, and relaxation of S-(-)-Bay 8644-precontracted isolated guinea pig ileum jointly suggest that suggesting that the L-subtype Cav channel is involved in spasmolytic action of EOPI. Treatment with EOPI dose dependently (7.5, 15 and 30 mg/kg i.p.) inhibited lipopolysaccharide- induced increased in total cell count, neutrophil count, nitrate-nitrite, total protein, albumin levels in bronchoalveolar fluid and myeloperoxidase levels in lung homogenates. Mild diffused lesions involving focal interalveolar septal, intraluminal infiltration of neutrophils were observed in EOPI (7.5 &15 mg/kg) pretreated while no abnormality was detected in EOPI (30 mg/kg) and roflumilast (1mg/kg) pretreated rats. Roflumilast was used as standard. EOPI reduced the respiratory flow due to gasping in ovalbumin sensitized guinea pigs. The study demonstrates the effectiveness of EOPI in bronchial asthma possibly related to its ability to inhibit L-subtype Cav channel, mast cell stabilization, antioxidant, angiostatic and through inhibition of 5-lipoxygenase enzyme. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=asthma" title="asthma">asthma</a>, <a href="https://publications.waset.org/abstracts/search?q=lipopolysaccharide" title=" lipopolysaccharide"> lipopolysaccharide</a>, <a href="https://publications.waset.org/abstracts/search?q=spirometry" title=" spirometry"> spirometry</a>, <a href="https://publications.waset.org/abstracts/search?q=Pistacia%20integerrima%20J.L.%20Stewart%20ex%20Brandis" title=" Pistacia integerrima J.L.

The term intellectual capital was popularized in the 1990s by Thomas Stewart. “Intellectual capital is the knowledge, applied experience, enterprise processes and technology customer relationship and professional skills which are valuable assets to an organization.” Human capital – includes employee brainpower, competence, skills, experience and knowledge. Customer capital – includes relations and networks with partners, suppliers, distributors, and customers. The objective of the article is to assess one of the key components of organizational culture – organizational values. The focus of the survey was on assessing how intellectual capital presented in these values of the organization. In the conclusion section the article refers to underestimation of intellectual capital by the organization management and the various possible negative effects of the latter. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=human%20capital" title="human capital">human capital</a>, <a href="https://publications.waset.org/abstracts/search?q=intellectual%20capital" title=" intellectual capital"> intellectual capital</a>, <a href="https://publications.waset.org/abstracts/search?q=organizational%20culture" title=" organizational culture"> organizational culture</a>, <a href="https://publications.waset.org/abstracts/search?q=management" title=" management"> management</a>, <a href="https://publications.waset.org/abstracts/search?q=social%20identity" title=" social identity"> social identity</a>, <a href="https://publications.waset.org/abstracts/search?q=organization" title=" organization"> organization</a> </p> <a href="https://publications.waset.org/abstracts/19393/features-valuation-of-intellectual-capital-in-the-organization" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/19393.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">464</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">29</span> Optimal Design of Redundant Hybrid Manipulator for Minimum Singularity</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arash%20Rahmani">Arash Rahmani</a>, <a href="https://publications.waset.org/abstracts/search?q=Ahmad%20Ghanbari"> Ahmad Ghanbari</a>, <a href="https://publications.waset.org/abstracts/search?q=Abbas%20Baghernezhad"> Abbas Baghernezhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Babak%20Safaei"> Babak Safaei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the design of parallel manipulators, usually mean value of a dexterity measure over the workspace volume is considered as the objective function to be used in optimization algorithms. The mentioned indexes in a hybrid parallel manipulator (HPM) are quite complicated to solve thanks to infinite solutions for every point within the workspace of the redundant manipulators. In this paper, spatial isotropic design axioms are extended as a well-known method for optimum design of manipulators. An upper limit for the isotropy measure of HPM is calculated and instead of computing and minimizing isotropy measure, minimizing the obtained limit is considered. To this end, two different objective functions are suggested which are obtained from objective functions of comprising modules. Finally, by using genetic algorithm (GA), the best geometric parameters for a specific hybrid parallel robot which is composed of two modified Gough-Stewart platforms (MGSP) are achieved. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hybrid%20manipulator" title="hybrid manipulator">hybrid manipulator</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20isotropy" title=" spatial isotropy"> spatial isotropy</a>, <a href="https://publications.waset.org/abstracts/search?q=genetic%20algorithm" title=" genetic algorithm"> genetic algorithm</a>, <a href="https://publications.waset.org/abstracts/search?q=optimum%20design" title=" optimum design"> optimum design</a> </p> <a href="https://publications.waset.org/abstracts/41885/optimal-design-of-redundant-hybrid-manipulator-for-minimum-singularity" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41885.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">336</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">28</span> Polyvictimization and the Risk of Harm to Self and Others among Children and Youth</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shannon%20L.%20Stewart">Shannon L.

The goal of this study was to examine the relationship between polyvictimization (multiple types of trauma) and risk of harm to self and others, taking into account possible age and sex differences. A total of 8980 children and youth were recruited from over 50 mental health facilities across Ontario, Canada. Among this sample, 29% of children and youth had experienced polyvictimization. Results showed that female children and youth who had experienced trauma were at greater risk of harm to themselves, while their male counterparts were at greater risk of harming others. Further, findings from this study highlight that experiencing polyvictimization, regardless of age or sex, increased the risk of harm to self and others. These findings add to extant literature as to the cumulative relationship between polyvictimization and risk in relation to harming oneself or others. Further, results from this study have significant implications for assessment and care-planning for those children and youth presenting with a trauma background. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=children%27s%20mental%20health" title="children's mental health">children's mental health</a>, <a href="https://publications.waset.org/abstracts/search?q=polyvictimization" title=" polyvictimization"> polyvictimization</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20of%20harm" title=" risk of harm"> risk of harm</a>, <a href="https://publications.waset.org/abstracts/search?q=sex%20differences" title=" sex differences"> sex differences</a> </p> <a href="https://publications.waset.org/abstracts/127845/polyvictimization-and-the-risk-of-harm-to-self-and-others-among-children-and-youth" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/127845.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">134</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">27</span> Transforming Water-Energy-Gas Industry through Smart Metering and Blockchain Technology</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khoi%20A.%20Nguyen">Khoi A.

It is Indonesian culture that women act as household managers. Therefore, women as household managers hold an important role in reducing food waste within households. Meanwhile, in the community, women’s organisations are some of the most active organisations dealing with food waste. Food waste has an increasing profile and is the subject of much global attention and have economic, social and environmental impacts. Reducing food waste will improve future food availability in the context of global population growth and increasing resource scarcity. The aim of this research is to investigate women’s experience and understanding of dealing with food waste in the household and in the community. The research will use an inductive approach using in-depth qualitative methods. In terms of data collection, two methods will be used - questionnaire and interviews. All in all, it could be claimed that women, both within the household and the community in Indonesia, hold an important role in dealing with food waste. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=community%20waste%20management" title="community waste management">community waste management</a>, <a href="https://publications.waset.org/abstracts/search?q=food%20waste" title=" food waste"> food waste</a>, <a href="https://publications.waset.org/abstracts/search?q=gender" title=" gender"> gender</a>, <a href="https://publications.waset.org/abstracts/search?q=household%20waste" title=" household waste"> household waste</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20management" title=" waste management"> waste management</a> </p> <a href="https://publications.waset.org/abstracts/85101/gender-perception-on-food-waste-within-the-household-and-community-case-study-in-bandung-city-indonesia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/85101.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">236</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">25</span> Indigenous Healers and Indigenous Trauma: Healing at the Intersections of Colonial, Intergenerational, and Individual Trauma for Indigenous Peoples in Canada</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Suzanne%20L.%20Stewart">Suzanne L.

The earlier studies did not elaborate on the relationship between energy consumption and IEQ in office buildings. Such a relationship can provide a comprehensive overview of the building's performance. Also, it would find the potential of already constructed buildings under the upcoming climate change. A commercial building in southeast Queensland, Australia, was evaluated in this study. Physical measurements of IEQ and Energy areconducted, and their relationship will be determined using statistical analysis. The case study building is modelled in TRNSys software, and it will be validatedusingthe actual building's BMS data. Then, the modelled buildingwill be simulated by predicted weather data developed by the commonwealth scientific and industrial research organisation of Australia to investigate the occupant resilience and energy consumption.

Test cases are executed against the mutant code to determine if one fails, detects the error and ensures the program is correct. One major issue with this type of testing was it became intensive computationally to generate and test all possible mutations for complex programs. This paper used reinforcement learning and parallel processing within the context of mutation testing for the selection of mutation operators and test cases that reduced the computational cost of testing and improved test suite effectiveness. Experiments were conducted using sample programs to determine how well the reinforcement learning-based algorithm performed with one live mutation, multiple live mutations and no live mutations. The experiments, measured by mutation score, were used to update the algorithm and improved accuracy for predictions. The performance was then evaluated on multiple processor computers. With reinforcement learning, the mutation operators utilized were reduced by 50 – 100%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=automated-testing" title="automated-testing">automated-testing</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=mutation%20testing" title=" mutation testing"> mutation testing</a>, <a href="https://publications.waset.org/abstracts/search?q=parallel%20processing" title=" parallel processing"> parallel processing</a>, <a href="https://publications.waset.org/abstracts/search?q=reinforcement%20learning" title=" reinforcement learning"> reinforcement learning</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20engineering" title=" software engineering"> software engineering</a>, <a href="https://publications.waset.org/abstracts/search?q=software%20testing" title=" software testing"> software testing</a> </p> <a href="https://publications.waset.org/abstracts/141195/machine-learning-approach-for-mutation-testing" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141195.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">198</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">22</span> Improving Decision Support for Organ Transplant</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ian%20McCulloh">Ian McCulloh</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrew%20Placona"> Andrew Placona</a>, <a href="https://publications.waset.org/abstracts/search?q=Darren%20Stewart"> Darren Stewart</a>, <a href="https://publications.waset.org/abstracts/search?q=Daniel%20Gause"> Daniel Gause</a>, <a href="https://publications.waset.org/abstracts/search?q=Kevin%20Kiernan"> Kevin Kiernan</a>, <a href="https://publications.waset.org/abstracts/search?q=Morgan%20Stuart"> Morgan Stuart</a>, <a href="https://publications.waset.org/abstracts/search?q=Christopher%20Zinner"> Christopher Zinner</a>, <a href="https://publications.waset.org/abstracts/search?q=Laura%20Cartwright"> Laura Cartwright</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An estimated 22-25% of viable deceased donor kidneys are discarded every year in the US, while waitlisted candidates are dying every day. As many as 85% of transplanted organs are refused at least once for a patient that scored higher on the match list. There are hundreds of clinical variables involved in making a clinical transplant decision and there is rarely an ideal match. Decision makers exhibit an optimism bias where they may refuse an organ offer assuming a better match is imminent. We propose a semi-parametric Cox proportional hazard model, augmented by an accelerated failure time model based on patient specific suitable organ supply and demand to estimate a time-to-next-offer. Performance is assessed with Cox-Snell residuals and decision curve analysis, demonstrating improved decision support for up to a 5-year outlook. Providing clinical decision makers with quantitative evidence of likely patient outcomes (e.g., time to next offer and the mortality associated with waiting) may improve decisions and reduce optimism bias, thus reducing discarded organs and matching more patients on the waitlist. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=decision%20science" title="decision science">decision science</a>, <a href="https://publications.waset.org/abstracts/search?q=KDPI" title=" KDPI"> KDPI</a>, <a href="https://publications.waset.org/abstracts/search?q=optimism%20bias" title=" optimism bias"> optimism bias</a>, <a href="https://publications.waset.org/abstracts/search?q=organ%20transplant" title=" organ transplant"> organ transplant</a> </p> <a href="https://publications.waset.org/abstracts/160221/improving-decision-support-for-organ-transplant" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160221.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">105</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">21</span> Tapping into Debt: The Effect of Contactless Payment Methods on Overdraft Fee Occurrence</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Merle%20Van%20Den%20Akker">Merle Van Den Akker</a>, <a href="https://publications.waset.org/abstracts/search?q=Neil%20Stewart"> Neil Stewart</a>, <a href="https://publications.waset.org/abstracts/search?q=Andrea%20Isoni"> Andrea Isoni</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Contactless methods of payment referred to as tap&go, have become increasingly popular globally. However, little is known about the consequences of this payment method on spending, spending habits, personal finance management, and debt accumulation. The literature on other payment methods such as credit cards suggests that, through increased ease and reduced friction, the pain of paying in these methods is reduced, leading to higher and more frequent spending, resulting in higher debt accumulation. Within this research, we use a dataset of 300 million transactions of 165.000 individuals to see whether the onset of using contactless methods of payment increases the occurrence of overdraft fees. Using the R package MatchIt, we find, when matching people on initial overdraft occurrence and salary, that people who do start using contactless incur a significantly higher number of overdraft fees, as compared to those who do not start using contactless in the same year. Having accounted for income, opting-in, and time-of-year effects, these results show that contactless methods of payment fall within the scope of earlier theories on credit cards, such as the pain of paying, meaning that this payment method leads to increasing difficulties managing personal finance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=contactless" title="contactless">contactless</a>, <a href="https://publications.waset.org/abstracts/search?q=debt%20accumulation" title=" debt accumulation"> debt accumulation</a>, <a href="https://publications.waset.org/abstracts/search?q=overdraft%20fees" title=" overdraft fees"> overdraft fees</a>, <a href="https://publications.waset.org/abstracts/search?q=payment%20methods" title=" payment methods"> payment methods</a>, <a href="https://publications.waset.org/abstracts/search?q=spending" title=" spending"> spending</a> </p> <a href="https://publications.waset.org/abstracts/114333/tapping-into-debt-the-effect-of-contactless-payment-methods-on-overdraft-fee-occurrence" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/114333.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">122</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">20</span> Sexual Behaviors and Condom Attitude among Injecting Drug Users in Hai Phong, Vietnam: Qualitative Findings</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tanvir%20Ahmed">Tanvir Ahmed</a>, <a href="https://publications.waset.org/abstracts/search?q=Thanh%20N.%20Long"> Thanh N.

Fifteen IDUs participated and two local interviewers conducted qualitative semi-structured face-to-face interviews in September-October, 2012 in Vietnamese language. Data were analyzed thematically. Non-protective condom attitudes include negotiate or convince Female Sex Workers (FSW); not realizing risk, importance or necessity; partner doesn’t like, and having extra money/drug from clients. On the other hand, self-awareness, family-consciousness, suspicion of STI presence, fear of getting HIV, and client negotiation sometimes resulted in a safe-sex practice. A thematic diagram was developed to present the relationship (strong/weak) between condom attitude and sexual practice (safe/unsafe) by partner types. The experiences and views reflected in the qualitative information emphasize the heightened need for safe-sex education especially among young IDUs (male/female) highlighting sexual transmission risk. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AIDS" title="AIDS">AIDS</a>, <a href="https://publications.waset.org/abstracts/search?q=HIV" title=" HIV"> HIV</a>, <a href="https://publications.waset.org/abstracts/search?q=injecting%20drug%20user" title=" injecting drug user"> injecting drug user</a>, <a href="https://publications.waset.org/abstracts/search?q=risk%20behaviors" title=" risk behaviors"> risk behaviors</a>, <a href="https://publications.waset.org/abstracts/search?q=Vietnam" title=" Vietnam "> Vietnam </a> </p> <a href="https://publications.waset.org/abstracts/4419/sexual-behaviors-and-condom-attitude-among-injecting-drug-users-in-hai-phong-vietnam-qualitative-findings" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4419.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">857</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">19</span> Governance of the Waters in the Upper Iguazu Watershed: Case Study in Passaúna and Miringuava Watersheds</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Matheus%20Fonseca%20Dur%C3%A3es">Matheus Fonseca Durães</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruno%20da%20Silva%20Pereira"> Bruno da Silva Pereira</a>, <a href="https://publications.waset.org/abstracts/search?q=Bruna%20Stewart"> Bruna Stewart</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The concept of Brazil’s water governance has been the topic of discussion and has undergone legal and organizational improvements due to the need to promote a more effective and sustainable relationship with natural resources and stemming from conflicts related to shortcomings in decision-making. The Waters Act has enabled Brazil to create interesting mechanisms for integrated management, but, on the other hand, it has created a challenge that involves the implementation of the principles established in this legal framework. This study aims to evaluate some challenges and opportunities for water governance in two watersheds based on data collection and analysis of concessions, the water use register, and flow data. The elements presented demonstrated, via an analysis of legally instituted criteria, that the level of commitment of water resources is high, especially to public supply, and the adoption of the reference flow constituted one of the main barriers to implementing an efficient system, demonstrating the need for a regulatory policy that considers the hydrological behavior of the watersheds. Finally, the current water management model presents challenges to be addressed to achieve the objectives proposed by the water policy, such as ensuring sustainable, rational, and integrated use of water resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=management" title="management">management</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrology" title=" hydrology"> hydrology</a>, <a href="https://publications.waset.org/abstracts/search?q=public%20policies" title=" public policies"> public policies</a>, <a href="https://publications.waset.org/abstracts/search?q=Brazil" title=" Brazil"> Brazil</a> </p> <a href="https://publications.waset.org/abstracts/144761/governance-of-the-waters-in-the-upper-iguazu-watershed-case-study-in-passauna-and-miringuava-watersheds" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/144761.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">95</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> Parathyroid Hormone Receptor 1 as a Prognostic Indicator in Canine Osteosarcoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Awf%20A.%20Al-Khan">Awf A.

In addition to their critical roles in bone formation and remodeling, parathyroid hormone-related protein (PTHrP) and its receptor (PTHR1) are involved in progression and metastasis of many types of tumours in humans. The aims of this study were to determine the localisation and expression levels of PTHrP and PTHR1 in canine OS tissues using immunohistochemistry and to investigate if this expression is correlated with survival time. Formalin-fixed, paraffin-embedded tissue samples from 44 dogs with known survival time that had been diagnosed with primary osteosarcoma were analysed for localisation of PTHrP and PTHR1. Findings showed that both PTHrP and PTHR1 were present in all OS samples. The dogs with high level of PTHR1 protein (16%) had decreased survival time (P<0.05) compared to dogs with less PTHR1 protein. PTHrP levels did not correlate with survival time (P>0.05). The results of this study indicate that the PTHR1 is expressed differently in canine OS tissues and this may be correlated with poor prognosis. This may mean that PTHR1 may be useful as a prognostic indicator in canine OS and could represent a good therapeutic target in OS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dog" title="dog">dog</a>, <a href="https://publications.waset.org/abstracts/search?q=expression" title=" expression"> expression</a>, <a href="https://publications.waset.org/abstracts/search?q=osteosarcoma" title=" osteosarcoma"> osteosarcoma</a>, <a href="https://publications.waset.org/abstracts/search?q=parathyroid%20hormone%20receptor%201%20%28PTHR1%29" title=" parathyroid hormone receptor 1 (PTHR1)"> parathyroid hormone receptor 1 (PTHR1)</a>, <a href="https://publications.waset.org/abstracts/search?q=parathyroid%20hormone-related%20protein%20%28PTHrP%29" title=" parathyroid hormone-related protein (PTHrP)"> parathyroid hormone-related protein (PTHrP)</a>, <a href="https://publications.waset.org/abstracts/search?q=survival" title=" survival"> survival</a> </p> <a href="https://publications.waset.org/abstracts/55383/parathyroid-hormone-receptor-1-as-a-prognostic-indicator-in-canine-osteosarcoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/55383.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">275</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">17</span> Optimization of Alkali Silicate Glass Heat Treatment for the Improvement of Thermal Expansion and Flexural Strength</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stephanie%20Guerra-Arias">Stephanie Guerra-Arias</a>, <a href="https://publications.waset.org/abstracts/search?q=Stephani%20Nevarez"> Stephani Nevarez</a>, <a href="https://publications.waset.org/abstracts/search?q=Calvin%20Stewart"> Calvin Stewart</a>, <a href="https://publications.waset.org/abstracts/search?q=Rachel%20Grodsky"> Rachel Grodsky</a>, <a href="https://publications.waset.org/abstracts/search?q=Denis%20Eichorst"> Denis Eichorst</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The objective of this study is to describe the framework for optimizing the heat treatment of alkali silicate glasses, to enhance the performance of hermetic seals in extreme environments. When connectors are exposed to elevated temperatures, residual stresses develop due to the mismatch of thermal expansions between the glass, metal pin, and metal shell. Excessive thermal expansion mismatch compromises the reliability of hermetic seals. In this study, a series of heat treatment schedules will be performed on two commercial sealing glasses (one conventional sealing glass and one crystallizable sealing glass) using a design of experiments (DOE) approach. The coefficient of thermal expansion (CTE) will be measured pre- and post-heat treatment using thermomechanical analysis (TMA). Afterwards, the flexural strength of the specimen will be measured using a four-point bend fixture mounted in a static universal testing machine. The measured material properties will be statistically analyzed using MiniTab software to determine which factors of the heat treatment process have a strong correlation to the coefficient of thermal expansion and/or flexural strength. Finally, a heat-treatment will be designed and tested to ensure the optimal performance of the hermetic seals in connectors. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=glass-ceramics" title="glass-ceramics">glass-ceramics</a>, <a href="https://publications.waset.org/abstracts/search?q=design%20of%20experiment" title=" design of experiment"> design of experiment</a>, <a href="https://publications.waset.org/abstracts/search?q=hermetic%20connectors" title=" hermetic connectors"> hermetic connectors</a>, <a href="https://publications.waset.org/abstracts/search?q=material%20characterization" title=" material characterization"> material characterization</a> </p> <a href="https://publications.waset.org/abstracts/134575/optimization-of-alkali-silicate-glass-heat-treatment-for-the-improvement-of-thermal-expansion-and-flexural-strength" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/134575.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">150</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">16</span> An Analysis of a Relational Frame Skills Training Intervention to Increase General Intelligence in Early Childhood</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ian%20M.%20Grey">Ian M.

The hypothesis is that teaching young children to derive various relations between stimuli leads to increases in full-scale IQ scores of typically developing children. In the experimental group, sixteen 6-7-year-old children were exposed over six weeks to an intensive training intervention designed specifically for their age group. This training intervention, presented on a tablet, aimed to improve their understanding of the relations Same, Opposite, Different, contextual control over the concept of Sameness and Difference, and purely arbitrary derived relational responding for Sameness and Difference. In the control group, sixteen 6-7-year-old children interacted with KIBO robotics over six weeks. KIBO purports to improve cognitive skills through engagement with STEAM activities. Increases in full-scale IQ were recorded for most children in the experimental group, while no increases in full-scale IQ were recorded for the control group. These findings support the hypothesis that relational skills underlie many aspects of general cognitive ability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=early%20childhood" title="early childhood">early childhood</a>, <a href="https://publications.waset.org/abstracts/search?q=derived%20relational%20responding" title=" derived relational responding"> derived relational responding</a>, <a href="https://publications.waset.org/abstracts/search?q=intelligence" title=" intelligence"> intelligence</a>, <a href="https://publications.waset.org/abstracts/search?q=relational%20frame%20theory" title=" relational frame theory"> relational frame theory</a>, <a href="https://publications.waset.org/abstracts/search?q=relational%20skills" title=" relational skills"> relational skills</a> </p> <a href="https://publications.waset.org/abstracts/95579/an-analysis-of-a-relational-frame-skills-training-intervention-to-increase-general-intelligence-in-early-childhood" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/95579.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">184</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">15</span> Computational Fluid Dynamics Analysis of Convergent–Divergent Nozzle and Comparison against Theoretical and Experimental Results</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stewart%20A.%20Keir">Stewart A.

The geometry used in the analytical study and CFD model is taken from the experimental rig. The analytical study is undertaken using isentropic and adiabatic relationships and the output of the analytical study, the 'shockwave location tool', is created. The results from the analytical study are then used to optimize the redesign an experimental rig for more favorable placement of pressure taps and gain a much better representation of the shockwaves occurring in the divergent section of the nozzle. The CFD model is then optimized through the selection of different parameters, e.g. turbulence models (Spalart-Almaras, Realizable k-epsilon & Standard k-omega) in order to develop an accurate, robust model. The results from the CFD model can then be directly compared to experimental and analytical results in order to gauge the accuracy of each method of analysis. The CFD model will be used to visualize the variation of various parameters such as velocity/Mach number, pressure and turbulence across the shock. The CFD results will be used to investigate the interaction between the shock wave and the boundary layer. The validated model can then be used to modify the nozzle designs which may offer better performance and ease of manufacture and may present feasible improvements to existing high-speed flow applications. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=CFD" title="CFD">CFD</a>, <a href="https://publications.waset.org/abstracts/search?q=nozzle" title=" nozzle"> nozzle</a>, <a href="https://publications.waset.org/abstracts/search?q=fluent" title=" fluent"> fluent</a>, <a href="https://publications.waset.org/abstracts/search?q=gas%20dynamics" title=" gas dynamics"> gas dynamics</a>, <a href="https://publications.waset.org/abstracts/search?q=shock-wave" title=" shock-wave"> shock-wave</a> </p> <a href="https://publications.waset.org/abstracts/70928/computational-fluid-dynamics-analysis-of-convergent-divergent-nozzle-and-comparison-against-theoretical-and-experimental-results" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70928.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">232</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">14</span> Hybrid Heat Pump for Micro Heat Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=J.%20M.%20Counsell">J.

Heat currently accounts for 48% of UK energy consumption and approximately one third of UK’s greenhouse gas emissions. Heat Networks are being promoted by UK investment policies as one means of supporting hybrid heat pump based solutions. To this effect the RISE (Renewable Integrated and Sustainable Electric) heating system project is investigating how an all-electric heating sourceshybrid configuration could play a key role in long-term decarbonisation of heat.  For the purposes of this study, hybrid systems are defined as systems combining the technologies of an electric driven air source heat pump, electric powered thermal storage, a thermal vessel and micro-heat network as an integrated system.  This hybrid strategy allows for the system to store up energy during periods of low electricity demand from the national grid, turning it into a dynamic supply of low cost heat which is utilized only when required. Currently a prototype of such a system is being tested in a modern house integrated with advanced controls and sensors. This paper presents the virtual performance analysis of the system and its design for a micro heat network with multiple dwelling units. The results show that the RISE system is controllable and can reduce carbon emissions whilst being competitive in running costs with a conventional gas boiler heating system. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=gas%20boilers" title="gas boilers">gas boilers</a>, <a href="https://publications.waset.org/abstracts/search?q=heat%20pumps" title=" heat pumps"> heat pumps</a>, <a href="https://publications.waset.org/abstracts/search?q=hybrid%20heating%20and%20thermal%20storage" title=" hybrid heating and thermal storage"> hybrid heating and thermal storage</a>, <a href="https://publications.waset.org/abstracts/search?q=renewable%20integrated%20and%20sustainable%20electric" title=" renewable integrated and sustainable electric"> renewable integrated and sustainable electric</a> </p> <a href="https://publications.waset.org/abstracts/72727/hybrid-heat-pump-for-micro-heat-network" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72727.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">419</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">13</span> Human Metabolism of the Drug Candidate PBTZ169</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vadim%20Makarov">Vadim Makarov</a>, <a href="https://publications.waset.org/abstracts/search?q=Stewart%20T.Cole"> Stewart T.Cole</a> </p> <p class="card-text"><strong>Abstract:</strong></p> PBTZ169 is novel drug candidate with high efficacy in animals models, and its combination treatment of PBTZ169 with BDQ and pyrazinamide was shown to be more efficacious than the standard treatment for tuberculosis in a mouse model. The target of PBTZ169 is famous DprE1, an essential enzyme in cell wall biosynthesis. The crystal structure of the DprE1-PBTZ169 complex reveals formation of a semimercaptal adduct with Cys387 in the active site and explains the irreversible inactivation of the enzyme. Furthermore, this drug candidate demonstrated during preclinical research ‘drug like’ properties what made it an attractive drug candidate to treat tuberculosis in humans. During first clinical trials several cohorts of the healthy volunteers were treated by the single doses of PBTZ169 as well as two weeks repeated treatment was chosen for two maximal doses. As expected PBTZ169 was well tolerated, and no significant toxicity effects were observed during the trials. The study of the metabolism shown that human metabolism of PBTZ169 is very different from microbial or animals compound transformation. So main pathway of microbial, mice and less rats metabolism connected with reduction processes, but human metabolism mainly connected with oxidation processes. Due to this difference we observed several metabolites of PBTZ169 in humans with antitubercular activity, and now we can conclude that animal antituberculosis activity of PBTZ169 is a result not only activity of the drug itself, but it is a result of the sum activity of the drug and its metabolites. Direct antimicrobial plasma activity was studied, and such activity was observed for 24 hours after human treatment for some doses. This data gets high chance for good efficacy of PBTZ169 in human for treatment TB infection. Second phase of clinical trials was started summer of 2017 and continues to the present day. Available data will be presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clinical%20trials" title="clinical trials">clinical trials</a>, <a href="https://publications.waset.org/abstracts/search?q=DprE1" title=" DprE1"> DprE1</a>, <a href="https://publications.waset.org/abstracts/search?q=PBTZ169" title=" PBTZ169"> PBTZ169</a>, <a href="https://publications.waset.org/abstracts/search?q=metabolism" title=" metabolism"> metabolism</a> </p> <a href="https://publications.waset.org/abstracts/88320/human-metabolism-of-the-drug-candidate-pbtz169" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/88320.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">12</span> Hepatic Regenerative Capacity after Acetaminophen-Induced Liver Injury in Mouse Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20F.%20Hamid">N.

The mouse model of APAP has been extensively used for studies on pathogenesis and intervention of drug induced liver injury based on the CytP450 mediated formation of N-acetyl-p-benzo-quinoneimine and, more recently, as model for mechanism based biomarkers. Delay of the fasted CD1 mice to rebound to the basal level of hepatic GSH compare to fed mice is reported in this study. Histologically, 15 hours fasted mice prior to APAP treatment leading to overall more intense cell loss with no evidence of apoptosis as compared to non-fasted mice, where the apoptotic cells were clearly seen on cleaved caspase-3 immunostaining. After 15 hours post APAP administration, hepatocytes underwent stage of recovery with evidence of mitotic figures in fed mice and return to completely no histological difference to control at 24 hours. On the contrary, the evidence of ongoing cells damage and inflammatory cells infiltration are still present on fasted mice until the end of the study. To further measure the regenerative capacity of the hepatocytes, the inflammatory mediators of cytokines that involved in the progression or regression of the toxicity like TNF-α and IL-6 in liver and spleen using RT-qPCR were also included. Yet, quantification of proliferating cell nuclear antigen (PCNA) has demonstrated the time for hepatic regenerative in fasted is longer than that to fed mice. Together, these data would probably confirm that fasting prior to APAP treatment does not only modulate liver injury, but could have further effects to delay subsequent regeneration of the hepatocytes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=acetaminophen" title="acetaminophen">acetaminophen</a>, <a href="https://publications.waset.org/abstracts/search?q=liver" title=" liver"> liver</a>, <a href="https://publications.waset.org/abstracts/search?q=proliferating%20cell%20nuclear%20antigen" title=" proliferating cell nuclear antigen"> proliferating cell nuclear antigen</a>, <a href="https://publications.waset.org/abstracts/search?q=regeneration" title=" regeneration"> regeneration</a>, <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title=" apoptosis"> apoptosis</a> </p> <a href="https://publications.waset.org/abstracts/21901/hepatic-regenerative-capacity-after-acetaminophen-induced-liver-injury-in-mouse-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21901.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">431</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> The Simultaneous Application of Chemical and Biological Markers to Identify Reliable Indicators of Untreated Human Waste and Fecal Pollution in Urban Philadelphia Source Waters</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Stafford%20Stewart">Stafford Stewart</a>, <a href="https://publications.waset.org/abstracts/search?q=Hui%20Yu"> Hui Yu</a>, <a href="https://publications.waset.org/abstracts/search?q=Rominder%20Suri"> Rominder Suri</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper publishes the results of the first known study conducted in urban Philadelphia waterways that simultaneously utilized anthropogenic chemical and biological markers to identify suitable indicators of untreated human waste and fecal pollution. A total of 13 outfall samples, 30 surface water samples, and 2 groundwater samples were analyzed for fecal contamination and untreated human waste using a suite of 25 chemical markers and 5 bio-markers. Pearson rank correlation tests were conducted to establish associations between the abundances of bio-markers and the concentrations of chemical markers. Results show that 16S rRNA gene of human-associated Bacteroidales (BacH) was very strongly correlated (0.76 – 0.97, p < 0.05) with labile chemical markers acetaminophen, cotinine, estriol, and urobilin. Likewise, human-specific F- RNA coliphages (F-RNA-II) and labile chemical markers, urobilin, ibuprofen, cotinine and estriol, were significantly correlated (0.77 – 0.95, p < 0.05). Similarly, a strong positive correlation (0.67 – 0.91, p < 0.05) was evident between the abundances of bio-markers BacH and F-RNA-II, and the concentrations of the conservative markers, trimethoprim, meprobamate, diltiazem, triclocarban, metformin, sucralose, gemfibrozil, sulfamethoxazole, and carbamazepine. Human mitochondrial DNA (MitoH) correlated moderately with labile markers nicotine and salicylic acid as well as with conservative markers metformin and triclocarban (0.31 – 0.47, p<0.05). This study showed that by associating chemical and biological markers, a robust technique was developed for fingerprinting source-specific untreated waste and fecal contamination in source waters. <p
