Methods: This study used the Surveillance, Epidemiology, and End Results database to analyze the clinicopathological data of 50,218 patients with classic HCC and five rare subtypes (ICD-O-3 Histology Code=8170/3-8175/3) between 2004 and 2018. The annual percent change (APC) was calculated using Joinpoint regression, and a nomogram was developed based on multivariable competing risk survival analyses. The prognostic performance of the nomogram was evaluated using the Akaike information criterion, Bayesian information criterion, C-index, calibration curve, and area under the receiver operating characteristic curve. Decision curve analysis was used to assess the clinical value of the models. Results: The incidence of scirrhous carcinoma showed a decreasing trend (APC=-6.8%, P=0.025), while the morbidity of other rare subtypes remained stable from 2004 to 2018. The incidence-based mortality plateau in all subtypes during the period. Clear cell carcinoma was the most common subtype (n=551, 1.1%), followed by fibrolamellar (n=241, 0.5%), scirrhous (n=82, 0.2%), spindle cell (n=61, 0.1%), and pleomorphic (n=17, ~0%) carcinomas. Patients with fibrolamellar carcinoma were younger and more likely to have non-cirrhotic liver and better prognoses. Scirrhous carcinoma shared almost the same macro clinical characteristics and outcomes as classic HCC. Clear cell carcinoma tended to occur in the Asia-Pacific elderly male population, and more than half of them were large HCC (Size>5cm). Sarcomatoid (including spindle cell and pleomorphic) carcinoma was associated with larger tumor size, poorer differentiation, and more dismal prognoses. The pathological subtype, T stage, M stage, surgery, alpha-fetoprotein, and cancer history were identified as independent predictors in patients with rare subtypes. The nomogram showed good calibration, discrimination, and net benefits in clinical practice. Conclusion: The rare subtypes of HCC had distinct clinicopathological features and biological behaviors compared with classic HCC. Our findings could provide a valuable reference for clinicians. The constructed nomogram could accurately predict prognoses, which is beneficial for individualized management. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hepatocellular%20carcinoma" title="hepatocellular carcinoma">hepatocellular carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=pathological%20subtype" title=" pathological subtype"> pathological subtype</a>, <a href="https://publications.waset.org/abstracts/search?q=fibrolamellar%20carcinoma" title=" fibrolamellar carcinoma"> fibrolamellar carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=scirrhous%20carcinoma" title=" scirrhous carcinoma"> scirrhous carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=clear%20cell%20carcinoma" title=" clear cell carcinoma"> clear cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=spindle%20cell%20carcinoma" title=" spindle cell carcinoma"> spindle cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=pleomorphic%20carcinoma" title=" pleomorphic carcinoma"> pleomorphic carcinoma</a> </p> <a href="https://publications.waset.org/abstracts/163602/epidemiological-and-clinical-characteristics-of-five-rare-pathological-subtypes-of-hepatocellular-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163602.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">75</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">3878</span> Extrapulmonary Gastrointestinal Small Cell Carcinoma: A Single Institute Experience of 14 Patients from a Low Middle Income Country </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Awais%20Naeem">Awais Naeem</a>, <a href="https://publications.waset.org/abstracts/search?q=Osama%20Shakeel"> Osama Shakeel</a>, <a href="https://publications.waset.org/abstracts/search?q=Faizan%20Ullah"> Faizan Ullah</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdul%20Wahid%20Anwer"> Abdul Wahid Anwer</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Introduction: To study the clinic-pathological factors, diagnostic factors and survival of extra-pulmonary small cell carcinoma. Methodology: From 1995 to 2017 all patients with a diagnosis of extra-pulmonary small cell carcinoma were included in the study. Demographic variables and clinic-pathological factors were collected. Management of disease was recorded. Short and long term oncological outcomes were recorded. All data was entered and analyzed in SPSS version 21. Results: A total of 14 patients were included in the study. Median age was 53.42 +/- 16.1 years. There were 5 male and 9 female patients. Most common presentation was dysphagia in 16 patient among esophageal small cell carcinoma and while other patient had pain in abdomen. Mean duration of symptoms was 4.23+/-2.91 months .Most common site is esophagus (n=6) followed by gall bladder(n=3). Almost all of the patients received chemo-radiotherapy. Majority of the patient presented with extensive disease. Five patients (35.7%) died during the follow up period, two (14.3%) were alive and rest of the patients were lost to follow up. Mean follow up period was 22.92 months and median follow up was 15 months. Conclusion: Extra-pulmonary small cell carcinoma is rare and needs to be managed aggressively. All patients should be treated with both systemic and local therapies. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=small%20cell%20carcinoma%20of%20esophagus" title="small cell carcinoma of esophagus">small cell carcinoma of esophagus</a>, <a href="https://publications.waset.org/abstracts/search?q=extrapulmonary%20small%20cell%20carcinoma" title=" extrapulmonary small cell carcinoma"> extrapulmonary small cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20cell%20carcinoma%20of%20gall%20bladder" title=" small cell carcinoma of gall bladder"> small cell carcinoma of gall bladder</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20cell%20carcinoma%20of%20rectum" title=" small cell carcinoma of rectum"> small cell carcinoma of rectum</a>, <a href="https://publications.waset.org/abstracts/search?q=small%20cell%20carcinoma%20of%20stomach" title=" small cell carcinoma of stomach"> small cell carcinoma of stomach</a> </p> <a href="https://publications.waset.org/abstracts/104995/extrapulmonary-gastrointestinal-small-cell-carcinoma-a-single-institute-experience-of-14-patients-from-a-low-middle-income-country" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104995.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">156</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">3877</span> Machining Stability of a Milling Machine with Different Preloaded Spindle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jui-Pin%20Hung">Jui-Pin Hung</a>, <a href="https://publications.waset.org/abstracts/search?q=Qiao-Wen%20Chang"> Qiao-Wen Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kung-Da%20Wu"> Kung-Da Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yong-Run%20Chen"> Yong-Run Chen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was aimed to investigate the machining stability of a spindle tool with different preloaded amount. To this end, the vibration tests were conducted on the spindle unit with different preload to assess the dynamic characteristics and machining stability of the spindle unit. Current results demonstrate that the tool tip frequency response characteristics and the machining stabilities in X and Y direction are affected to change for spindle with different preload. As can be found from the results, a high preloaded spindle tool shows higher limited cutting depth at mid position, while a spindle with low preload shows a higher limited depth. This implies that the machining stability of spindle tool system is affected to vary by the machine frame structure. Besides, such an effect is quite different and varied with the preload of the spindle. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bearing%20preload" title="bearing preload">bearing preload</a>, <a href="https://publications.waset.org/abstracts/search?q=dynamic%20compliance" title=" dynamic compliance"> dynamic compliance</a>, <a href="https://publications.waset.org/abstracts/search?q=machining%20stability" title=" machining stability"> machining stability</a>, <a href="https://publications.waset.org/abstracts/search?q=spindle" title=" spindle"> spindle</a> </p> <a href="https://publications.waset.org/abstracts/30499/machining-stability-of-a-milling-machine-with-different-preloaded-spindle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/30499.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">386</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">3876</span> Synchronous Carcinoma Cervix with Vulvar Carcinoma in situ: A Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Bhushan%20Bhalgat">Bhushan Bhalgat</a>, <a href="https://publications.waset.org/abstracts/search?q=Suresh%20Singh"> Suresh Singh</a>, <a href="https://publications.waset.org/abstracts/search?q=Phanindra%20Swain"> Phanindra Swain</a>, <a href="https://publications.waset.org/abstracts/search?q=Kamal%20Kishore%20Lakhera"> Kamal Kishore Lakhera</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Carcinoma of cervix and carcinoma of vulva have been associated with common predisposing factors like human papillomavirus and smoking.

Diagnosis is based on lab reports, including urinalysis, renal function tests (RFTs), and electrolyte balance, along with imaging techniques. Organ failure and other complications have been commonly observed in these cases. Over the years, the presentation of patients has varied, so carcinoma was classified on the basis of site, shape, and consistency for detailed analysis. Lifestyle patterns and occupational history were inquired about and recorded. Methods: Data from 100 patients presenting to the oncology and nephrology department of Mayo Hospital in the year 2015-2020 were included in this retrospective study on a random basis. The study was specifically focused on three risk factors. Smoking, occupational exposures, and Hakim medicine are taken by the patient for any cause. After procurement of data, follow-up contacts of these patients were established, resulting in a detailed analysis of lifestyle. Conclusion: The inference drawn is a direct causal link between smoking, industrial workplace exposure, and Hakim medicine with the development of Renal Cell Carcinoma. It was shown in the majority of the patients and hence confirmed our hypothesis. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=renal%20cell%20carcinoma" title="renal cell carcinoma">renal cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=kidney%20cancer" title=" kidney cancer"> kidney cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=clear%20cell%20carcinoma" title=" clear cell carcinoma"> clear cell carcinoma</a> </p> <a href="https://publications.waset.org/abstracts/161412/etiological-factors-for-renal-cell-carcinoma-five-year-study-at-mayo-hospital-lahore" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161412.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">102</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">3874</span> Variation of the Dynamic Characteristics of a Spindle with the Change of Bearing Preload</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shinji%20Oouchi">Shinji Oouchi</a>, <a href="https://publications.waset.org/abstracts/search?q=Hajime%20Nomura"> Hajime Nomura</a>, <a href="https://publications.waset.org/abstracts/search?q=Kung-Da%20Wu"> Kung-Da Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Jui-Pin%20Hung"> Jui-Pin Hung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper presents the variation of the dynamic characteristics of a spindle with the change of bearing preload. The correlations between the variation of bearing preload and fundamental modal parameters were first examined by conducting vibration tests on physical spindle units. Experimental measurements show that the dynamic compliance and damping ratio associated with the dominating modes were affected to vary with variation of the bearing preload. When the bearing preload was slightly deviated from a standard value, the modal frequency and damping ability also vary to different extent, which further enable the spindle to perform with different compliance. For the spindle used in this study, a standard preload value set on bearings would enable the spindle to behave a higher stiffness as compared with others with a preload variation. This characteristic can be served as a reference to examine the variation of bearing preload of spindle in assemblage or operation. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20compliance" title="dynamic compliance">dynamic compliance</a>, <a href="https://publications.waset.org/abstracts/search?q=bearing%20preload" title=" bearing preload"> bearing preload</a>, <a href="https://publications.waset.org/abstracts/search?q=modal%20damping" title=" modal damping"> modal damping</a>, <a href="https://publications.waset.org/abstracts/search?q=standard%20preload" title=" standard preload"> standard preload</a> </p> <a href="https://publications.waset.org/abstracts/15889/variation-of-the-dynamic-characteristics-of-a-spindle-with-the-change-of-bearing-preload" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/15889.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">467</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">3873</span> Modeling of the Dynamic Characteristics of a Spindle with Experimental Validation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jhe-Hao%20Huang">Jhe-Hao Huang</a>, <a href="https://publications.waset.org/abstracts/search?q=Kun-Da%20Wu"> Kun-Da Wu</a>, <a href="https://publications.waset.org/abstracts/search?q=Wei-Cheng%20Shih"> Wei-Cheng Shih</a>, <a href="https://publications.waset.org/abstracts/search?q=Jui-Pin%20Hung"> Jui-Pin Hung</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study presented the investigation on the dynamic characteristics of a spindle tool system by experimental and finite element modeling approaches. As well known facts, the machining stability is greatly determined by the dynamic characteristics of the spindle tool system. Therefore, understanding the factors affecting dynamic behavior of a spindle tooling system is a prerequisite in dominating the final machining performance of machine tool system. To this purpose, a physical spindle unit was employed to assess the dynamic characteristics by vibration tests. Then, a three-dimensional finite element model of a high-speed spindle system integrated with tool holder was created to simulate the dynamic behaviors. For modeling the angular contact bearings, a series of spring elements were introduced between the inner and outer rings. The spring constant can be represented by the contact stiffness of the rolling bearing based on Hertz theory. The interface characteristic between spindle nose and tool holder taper can be quantified from the comparison of the measurements and predictions. According to the results obtained from experiments and finite element predictions, the vibration behavior of the spindle is dominated by the bending deformation of the spindle shaft in different modes, which is further determined by the stiffness of the bearings in spindle housing. Also, the spindle unit with tool holder shows a different dynamic behavior from that of spindle without tool holder. This indicates the interface property between tool holder and spindle nose plays an dominance on the dynamic characteristics the spindle tool system. Overall, the dynamic behaviors the spindle with and without tool holder can be successfully investigated through the finite element model proposed in this study. The prediction accuracy is determined by the modeling of the rolling interface of ball bearings in spindles and the interface characteristics between tool holder and spindle nose.

DOG1 immunostaining was found in 67 tumor types, including GIST (95.7%), esophageal squamous cell carcinoma (31.9%), pancreatic ductal adenocarcinoma (33.6%), adenocarcinoma of the Papilla Vateri (20%), squamous cell carcinoma of the vulva (15.8%) and the oral cavity (15.3%), mucinous ovarian cancer (15.3%), esophageal adenocarcinoma (12.5%), endometrioid endometrial cancer (12.1%), neuroendocrine carcinoma of the colon (11.1%) and diffuse gastric adenocarcinoma (11%). Low level-DOG1 immunostaining was seen in 17 additional tumor entities. DOG1 expression was unrelated to histopathological parameters of tumor aggressiveness and/or patient prognosis in cancers of the breast (n=1,002), urinary bladder (975), ovary (469), endometrium (173), stomach (233), and thyroid gland (512). High DOG1 expression was linked to estrogen receptor expression in breast cancer (p<0.0001) and the absence of HPV infection in squamous cell carcinomas (p=0.0008). In conclusion, our data identify several tumor entities that can show DOG1 expression levels at similar levels as in GIST. Although DOG1 is tightly linked to a diagnosis of GIST in spindle cell tumors, the differential diagnosis is much broader in DOG1 positive epithelioid neoplasms. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=biomarker" title="biomarker">biomarker</a>, <a href="https://publications.waset.org/abstracts/search?q=DOG1" title=" DOG1"> DOG1</a>, <a href="https://publications.waset.org/abstracts/search?q=immunohistochemistry" title=" immunohistochemistry"> immunohistochemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=tissue%20microarray" title=" tissue microarray"> tissue microarray</a> </p> <a href="https://publications.waset.org/abstracts/138403/dog1-expression-is-in-common-human-tumors-a-tissue-microarray-study-on-more-than-15000-tissue-samples" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138403.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">216</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">3871</span> Anticancer Effects of MicroRNA-1275 in Human Nasopharyngeal Carcinoma by Targeting HOXB5 </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cheng-Cao%20Sun">Cheng-Cao Sun</a>, <a href="https://publications.waset.org/abstracts/search?q=Shu-Jun%20Li"> Shu-Jun Li</a>, <a href="https://publications.waset.org/abstracts/search?q=De-Jia%20Li"> De-Jia Li</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Through analysis of a published micro-array-based high-throughput assessment, we discovered that miR-1275 was markedly down-regulated in nasopharyngeal carcinoma (NPC) tissues. However, little is known about its effect and mechanism involved in NPC development and progression. In this study, we investigated the role of miR-1275 on the development of NPC. The results indicated that miR-1275 was significantly down-regulated in primary NPC tissues, and very low levels were found in NPC cell lines. Ectopic expression of miR-1275 in NPC cell lines significantly suppressed cell growth as evidenced by cell viability assay and colony formation assay, through inhibition of HOXB5. In addition, miR-1275 suppresses G1/S transition through inhibition of HOXB5. Further, oncogene HOXB5 was revealed to be a putative target of miR-1275, which was inversely correlated with miR-1275 expression in NPC. Collectively, our study demonstrates that as a tumor suppressor, miR-1275 played a pivotal role on NPC through inhibiting cell proliferation, and suppressing G1/S transition by targeting oncogenic HOXB5. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microRNA-1275%20%28miR-1275%29" title="microRNA-1275 (miR-1275)">microRNA-1275 (miR-1275)</a>, <a href="https://publications.waset.org/abstracts/search?q=HOXB5" title=" HOXB5"> HOXB5</a>, <a href="https://publications.waset.org/abstracts/search?q=nasopharyngeal%20carcinoma" title=" nasopharyngeal carcinoma"> nasopharyngeal carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=proliferation" title=" proliferation"> proliferation</a> </p> <a href="https://publications.waset.org/abstracts/54943/anticancer-effects-of-microrna-1275-in-human-nasopharyngeal-carcinoma-by-targeting-hoxb5" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54943.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">264</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">3870</span> Predictive Value of Primary Tumor Depth for Cervical Lymphadenopathy in Squamous Cell Carcinoma of Buccal Mucosa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zohra%20Salim">Zohra Salim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Objective: To access the relationship of primary tumor thickness with cervical lymphadenopathy in squamous cell carcinoma of buccal mucosa. Methodology: A cross-sectional observational study was carried out on 80 Patients with biopsy-proven oral squamous cell carcinoma of buccal mucosa at Dow University of Health Sciences. All the study participants were treated with wide local excision of the primary tumor with elective neck dissection. Patients with prior head and neck malignancy or those with prior radiotherapy or chemotherapy were excluded from the study. Data was entered and analyzed on SPSS 21. Chi-squared test with 95% C.I and 80% power of the test was used to evaluate the relationship of tumor depth with cervical lymph nodes. Results: 50 participants were male, and 30 patients were female. 30 patients were in the age range of 20-40 years, 36 patients in the range of 40-60 years, while 14 patients were beyond age 60 years. Tumor size ranged from 0.3cm to 5cm with a mean of 2.03cm. Tumor depth ranged from 0.2cm to 5cm. 20% of the participants reported with tumor depth greater than 2.5cm, while 80% of patients reported with tumor depth less than 2.5cm. Out of 80 patients, 27 reported with negative lymph nodes, while 53 patients reported with positive lymph nodes.

Thymoquinone (TQ) is a naturally occurring compound drawing great attention as an anticancer and chemomodulator for chemotherapies. Herein, we studied the potential cytotoxicity of thymoquinone, CDDP and their combination against human oral squamous cell carcinoma cells in contrast to normal oral epithelial cells. CDDP similarly killed both head and neck squamous cell carcinoma cells (UMSCC-14C) and normal oral epithelial cells (OEC). TQ alone exerted considerable cytotoxicity against UMSCC-14C cells, while it induced a weaker killing effect against normal oral epithelial cells (OEC). The equitoxic combination of TQ and CDDP showed additive to synergistic interaction against both UMSCC-14C and OEC cells. TQ alone increased apoptotic cell fraction in UMSCC-14C cells as early as after 6 hours. In addition, prolonged exposure of UMSCC-14C to TQ alone resulted in 96.7±1.6% total apoptosis, which was increased after combination with CDDP to 99.3±1.2% in UMSCC-14C cells. On the other hand, TQ induced a marginal increase in the apoptosis in OEC and even decreased the apoptosis induced by CDDP alone. Finally, apoptosis induction results were confirmed by the change in the expression levels of p53, Bcl-2 and Caspase-9 proteins in both UMSCC-14c and OEC cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=thymoquinone" title="thymoquinone">thymoquinone</a>, <a href="https://publications.waset.org/abstracts/search?q=cisplatin" title=" cisplatin"> cisplatin</a>, <a href="https://publications.waset.org/abstracts/search?q=apoptosis" title=" apoptosis"> apoptosis</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20squamous%20cell%20carcinoma" title=" oral squamous cell carcinoma"> oral squamous cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=P53" title=" P53"> P53</a>, <a href="https://publications.waset.org/abstracts/search?q=Caspase-9" title=" Caspase-9"> Caspase-9</a>, <a href="https://publications.waset.org/abstracts/search?q=Bcl-2" title=" Bcl-2"> Bcl-2</a> </p> <a href="https://publications.waset.org/abstracts/173291/cytotoxicity-of-thymoquinone-alone-or-in-combination-with-cisplatin-cddp-against-oral-squamous-cell-carcinoma-in-vitro" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173291.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">66</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">3868</span> System Identification and Quantitative Feedback Theory Design of a Lathe Spindle</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Khairudin">M.

The dynamic of the lathe spindle is uncertain and time variation due to the deepness variation on cutting process. System identification was used to obtain the dynamics model of the lathe spindle. In this work, real time system identification is used to construct a linear model of the system from the nonlinear system. These linear models and its uncertainty bound can then be used for controller synthesis. The real time nonlinear system identification process to obtain a set of linear models of the lathe spindle that represents the operating ranges of the dynamic system. With a selected input signal, the data of output and response is acquired and nonlinear system identification is performed using Matlab to obtain a linear model of the system. Practical design steps are presented in which the QFT-based conditions are formulated to obtain a compensator and pre-filter to control the lathe spindle. The performances of the proposed controller are evaluated in terms of velocity responses of the the lathe machine spindle in corporating deepness on cutting process. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=lathe%20spindle" title="lathe spindle">lathe spindle</a>, <a href="https://publications.waset.org/abstracts/search?q=QFT" title=" QFT"> QFT</a>, <a href="https://publications.waset.org/abstracts/search?q=robust%20control" title=" robust control"> robust control</a>, <a href="https://publications.waset.org/abstracts/search?q=system%20identification" title=" system identification"> system identification</a> </p> <a href="https://publications.waset.org/abstracts/20793/system-identification-and-quantitative-feedback-theory-design-of-a-lathe-spindle" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20793.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">543</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">3867</span> Disruption of Cancer Cell Proliferation by Magnetic Field</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ming%20Ze%20Kao">Ming Ze Kao</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Static magnetic fields (SMF) are widely used in several medical applications, especially in diagnosis of tumors. However, biological effects of the SMFs on modulating cell physiology through the Lorentz force, which is highly frequency and magnitude dependent, remain to be elucidated. Specific patterns from SMFs of static MF, delivered by means of Halbach array magnets with a gradient increment of 6.857mT/mm from center to border, were found to have profound inhibitory effect on the growth rate of human cell line derived from Nasopharyngeal carcinoma patients. The SMFs, which were shown to be noncontact, selectively impact rapid dividing cells while quiescent cells stay intact. The phenomenon acts in two modes: the arrest of cell proliferation in the G2/M phase and destruction of cell mitosis in cell division. First mode is manifested by impacting the proper formation of mitotic spindle, whereas the second results in disintegration of the cancer cell. Both modes are demonstrated when SMF was applied for 24 hours to cancer cells, the results revealed that metaphase arrest during mitosis due to activation of DNA damage response (DDR), resulting in high expression of ATM-NBS1-CHEK signaling pathways and higher G2/M phase ratio compared with control group. Here, experimental data suggest that the SMFs cause activation of cell cycle checkpoints, which implies the MFs as a potential therapeutic modality as a sensitizer for radiotherapy or chemotherapy. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=static%20magnetic%20field" title="static magnetic field">static magnetic field</a>, <a href="https://publications.waset.org/abstracts/search?q=DNA%20damage%20response" title=" DNA damage response"> DNA damage response</a>, <a href="https://publications.waset.org/abstracts/search?q=Halbach%20array" title=" Halbach array"> Halbach array</a>, <a href="https://publications.waset.org/abstracts/search?q=magnetic%20therapy" title=" magnetic therapy"> magnetic therapy</a> </p> <a href="https://publications.waset.org/abstracts/98067/disruption-of-cancer-cell-proliferation-by-magnetic-field" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98067.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">114</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">3866</span> The Effect of Thymoquinone and Sorafenib Combination on Hepatocellular Carcinoma Cell Line</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Nabila%20N.%20El-Maraghy">Nabila N.

Methods: Hepatocellular Carcinoma HepG2 cell line was treated with Sorafenib and TQ individually and in combination. The effect of these treatments on cell viability (MTT assay), apoptosis (Expression of Caspase-3) and oxidative markers (GSH content and extent of lipid peroxidation) was determined. Results: When compared the effect of both agents alone and the combination of the IC50 of Sorafenib and the IC50 TQ, the combination resulted in reduction of cell inhibition and apoptosis and antagonize their actions on GSH content and extent of lipid peroxidation which are increased.

HLA-G also mediates tumor escape, but the immunosuppressive role is often neglected. These studies have focused on the examination of HLA-G expression in human breast carcinoma and HLA-G immunosuppressive role in NK cytolysis. We examined HLA-G expression in breast cell lines by real time PCR, ELISA and immunofluorescent staining. We treated the breast cancer cell lines with anti-human HLA-G antibody or progesterone. Then, NK cytolysis was measured by using MTT assay. We find that breast carcinoma cell lines increase the expression of HLA-G mRNA and protein, compared to normal cells. Blocking HLA-G of the breast cancer cells by the antibody increases NK cytolysis. Progesterone upregulates HLA-G mRNA and protein of human breast cancer cell lines. The increased HLA-G expression suppresses NK cytolysis. In summary, human breast carcinoma overexpress HLA-G immunosuppressive molecules. Blocking HLA-G protein by antibody improves NK cytolysis. In contrast, upregulation of HLA-G expression by progesterone impairs NK cytolytic function. Thus, HLA-G is a new immunosuppressive checkpoint and potential cancer immunotherapeutic target. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=HLA-G" title="HLA-G">HLA-G</a>, <a href="https://publications.waset.org/abstracts/search?q=Breast%20carcinoma" title=" Breast carcinoma"> Breast carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=NK%20cells" title=" NK cells"> NK cells</a>, <a href="https://publications.waset.org/abstracts/search?q=Immunosuppressive%20checkpoint" title=" Immunosuppressive checkpoint"> Immunosuppressive checkpoint</a> </p> <a href="https://publications.waset.org/abstracts/161283/hla-g-a-neglected-immunosuppressive-checkpoint-for-breast-cancer-immunotherapy" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/161283.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">88</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">3864</span> Sider Bee Honey: Antitumor Effect in Some Experimental Tumor Cell Lines</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Aliaa%20M.%20Issa">Aliaa M.

Honey is an effective agent for preventing, inhibiting and treating the growth of human and animal cancer cell lines in vitro and in vivo. The aim of the present study was to evaluate the impact of different dilutions from crude Sider honey and different duration times of exposure on the growth of six tumor cell lines (human cervical cancer cell line, HeLa; human hepatocellular carcinoma cell line, HepG-2; human larynx carcinoma cell line, Hep-2; brain tumor cell line, U251) as well as one animal cancerous cell line (Ehrlich ascites carcinoma cells line, EAC) and one normal cell line, Homo sapiens, human, (WISH) CCL-25. Different concentrations and treatment durations with Sider honey were tested on the growth of several cancer cell lines types. Histopathological changes in the tumor masses, animal survival, apoptosis and necrosis of the used cancer cell lines (using flow cytometry) were evaluated. Sider honey was administers either to the tumor mass itself by intratumoral injection or via drinking water. One-way ANOVA test was used for the analysis of (the means + standard error) of the optical density obtained from the Elisa reader and flow cytometry. The study revealed that different concentrations of Sider honey affected the growth patterns of all the studied cancer cell lines as well as their histopathological changes, and it depended on the cell line nature and the concentration of honey used. It is obvious that the relative animal survival percentage (bearing Ehrlich ascites carcinoma, EAC cells) was proportionally increased with the increase in the used honey concentrations. The study of apoptosis and necrosis using the flow cytometry technique emphasized the viability results. In conclusion, Sider honey was effective as antitumor agent, in the used concentrations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=antitumor" title="antitumor">antitumor</a>, <a href="https://publications.waset.org/abstracts/search?q=honey" title=" honey"> honey</a>, <a href="https://publications.waset.org/abstracts/search?q=sider" title=" sider"> sider</a>, <a href="https://publications.waset.org/abstracts/search?q=tumor%20cell%20lines" title=" tumor cell lines"> tumor cell lines</a> </p> <a href="https://publications.waset.org/abstracts/41053/sider-bee-honey-antitumor-effect-in-some-experimental-tumor-cell-lines" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/41053.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">537</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">3863</span> Closed Loop Large Bowel Obstruction Due to Appendiceal Signet Cell Carcinoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Joshua%20Teo">Joshua Teo</a>, <a href="https://publications.waset.org/abstracts/search?q=Leo%20Phan"> Leo Phan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Signet cell carcinoma of the appendix is the rarest and the most aggressive subtype of appendiceal malignancy, typically with non-specific presentations. We describe a case of a 62-year-old male with large bowel obstruction and CT demonstrating dilated large bowels from caecum to proximal sigmoid colon with pneumoperitoneum. Intra-operatively, closed-loop obstruction caused by dense adherence of sigmoid colon to caecum was noted, which had resulted in caecal perforation. Histopathology study indicated primary appendiceal malignancy of signet cell morphology with intra-peritoneal spread to the sigmoid colon. Large bowel obstruction from appendiceal malignancy has rarely been reported, and a similar presentation has not been described in the existing literature. When left-sided large bowel obstruction is suspected to be caused by a malignant stricture, it is essential to consider transperitoneal spread of appendiceal malignancy as potential aetiology, particularly in the elderly. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=appendiceal%20carcinoma" title="appendiceal carcinoma">appendiceal carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=large%20bowel%20obstruction" title=" large bowel obstruction"> large bowel obstruction</a>, <a href="https://publications.waset.org/abstracts/search?q=signet%20ring%20cell%20cancer" title=" signet ring cell cancer"> signet ring cell cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=caecal%20perforation" title=" caecal perforation"> caecal perforation</a> </p> <a href="https://publications.waset.org/abstracts/141362/closed-loop-large-bowel-obstruction-due-to-appendiceal-signet-cell-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/141362.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">222</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3862</span> Cytotoxicity and Apoptosis Activity of Areca catechu Linn.

Biji Pinang or areca nut (Areca catechu Linn.) has a high content of phenolics and flavonoids, and which is related to antioxidant activity. However, data on its effects on oral squamous cell carcinoma is not available. Objectives: Identification of the cytotoxicity and apoptosis activity in HSC-2 and HSC-3. Methods: The areca nut was extracted by ethanol 96%, MTS assay and apoptosis activity with flow cytometry. Results: The extract of areca nut showed higher toxicity on HSC-3 cell compared to HSC-2. The IC₅₀ of HSC-3 was 164.06 μg/ml vs. 629.50 μg/ml in HSC-2. There was an increase in late apoptosis percentage after 24 and 48 hours in HSC-2. There was a significant increase in early apoptosis percentage after 24 hours and late in 48 hours in HSC-3. Conclusion: The antioxidant activity of the extract of areca nut might be associated with the selective cytotoxicity on HSC-2 and HSC-3. Apoptosis is the major cell death mechanism involved.

The interface stiffness was produced by drawbar force on the tool holder, which tends to affect the spindle dynamics. In order to assess the influence of interface stiffness on the vibration characteristic of spindle unit, we first created a three dimensional finite element model of a high speed spindle system integrated with tool holder. The key point for the creation of FEM model is the modeling of the rolling interface within the angular contact bearings and the tool holder interface. The former can be simulated by a introducing a series of spring elements between inner and outer rings. The contact stiffness was calculated according to Hertz contact theory and the preload applied on the bearings. The interface stiffness of the tool holder was identified through the experimental measurement and finite element modal analysis. Current results show that the dynamic stiffness was greatly influenced by the tool holder system. In addition, variations of modal damping, static stiffness and dynamic stiffness of the spindle tool system were greatly determined by the interface stiffness of the tool holder which was in turn dependent on the draw bar force applied on the tool holder. Overall, this study demonstrates that identification of the interface characteristics of spindle tool holder is of very importance for the refinement of the spindle tooling system to achieve the optimum machining performance. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=dynamic%20stiffness" title="dynamic stiffness">dynamic stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=spindle-tool%20holder" title=" spindle-tool holder"> spindle-tool holder</a>, <a href="https://publications.waset.org/abstracts/search?q=interface%20stiffness" title=" interface stiffness"> interface stiffness</a>, <a href="https://publications.waset.org/abstracts/search?q=drawbar%20force" title=" drawbar force"> drawbar force</a> </p> <a href="https://publications.waset.org/abstracts/10212/effect-of-the-drawbar-force-on-the-dynamic-characteristics-of-a-spindle-tool-holder-system" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/10212.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">397</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">3860</span> Metastatic Esophageal Squamous Cell Carcinoma Presenting with COVID-19 Infection and Cardiac Tamponade</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sutinon%20Yuchomsuk">Sutinon Yuchomsuk</a>, <a href="https://publications.waset.org/abstracts/search?q=Satchachon%20Changthom"> Satchachon Changthom</a>, <a href="https://publications.waset.org/abstracts/search?q=Pruet%20Areesawangvong"> Pruet Areesawangvong</a>, <a href="https://publications.waset.org/abstracts/search?q=Monsiri%20Jinapen"> Monsiri Jinapen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Esophageal squamous cell carcinoma can be presented with many symptoms, such as dysphagia or weight loss. However, in some circumstances, rare presentations can be found, e.g., dyspnea, which is more common in pulmonary malignancy. And dyspnea is also one of the most common presentations of COVID-19 infection. So, in this case, we can learn from many points in patient symptoms and findings leading to the diagnosis of esophageal squamous cell carcinoma. Method: This research is a case-report study including one patient from Mahasarakham Hospital, Thailand. Data were collected during December 2021. Result: A 55-year-old Thai male patient with an unknown past medical history presented with dyspnea and shortness of breath for the duration of three days prior to admission. His symptom also included cough, fever, and sore throat. Laboratory results indicated that the patient had COVID-19 pneumonia. Further investigation showed that he had cardiac tamponade and suspected pulmonary/esophageal cancer. Lung biopsy and pericardiocentesis were done, which were positive for carcinoma from pericardial effusion but negative for malignancy from the lung biopsy. Later esophagogastroduodenoscopy was done with endoscopic tissue biopsy; the result was positive for squamous cell carcinoma of the esophagus. Conclusion: Most commonly, esophageal cancer is presented with dysphagia or weight loss. However, in some rare cases, patients can also be presented with dyspnea due to cardiac tamponade. And in recent years, COVID-19 has become a pandemic all over the world, sometimes masking symptoms of other diseases. Such as in this case, the patient didn’t improve after the pneumonia was resolved, which led to the final diagnosis of metastatic esophageal cancer. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=esophageal%20cancer" title="esophageal cancer">esophageal cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=cardiac%20tamponade" title=" cardiac tamponade"> cardiac tamponade</a>, <a href="https://publications.waset.org/abstracts/search?q=metastatic%20squamous%20cell%20carcinoma" title=" metastatic squamous cell carcinoma"> metastatic squamous cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=COVID-19%20infection" title=" COVID-19 infection"> COVID-19 infection</a> </p> <a href="https://publications.waset.org/abstracts/152632/metastatic-esophageal-squamous-cell-carcinoma-presenting-with-covid-19-infection-and-cardiac-tamponade" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152632.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">120</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">3859</span> Esophageal Premalignant and Malignant Epithelial Lesions: Pathological Characteristics and Value of Cyclooxygenase-2 Expression. </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Mohamed%20Abd%20Elmoneim">Hanan Mohamed Abd Elmoneim</a>, <a href="https://publications.waset.org/abstracts/search?q=Rawan%20Saleh%20AlJawi"> Rawan Saleh AlJawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Razan%20Saleh%20AlJawi"> Razan Saleh AlJawi</a>, <a href="https://publications.waset.org/abstracts/search?q=Aseel%20Abdullah%20AlMasoudi"> Aseel Abdullah AlMasoudi </a>, <a href="https://publications.waset.org/abstracts/search?q=Zyad%20Adnan%20Turkistani"> Zyad Adnan Turkistani</a>, <a href="https://publications.waset.org/abstracts/search?q=Anas%20Abdulkarim%20Alkhoutani"> Anas Abdulkarim Alkhoutani </a>, <a href="https://publications.waset.org/abstracts/search?q=Ohood%20Musaed%20AlJuhani"> Ohood Musaed AlJuhani </a>, <a href="https://publications.waset.org/abstracts/search?q=Hanan%20Attiyah%20AlZahrani"> Hanan Attiyah AlZahrani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background Esophageal cancer is the eighth most common cancer worldwide. More than 90% of esophageal cancers are either squamous cell carcinoma or adenocarcinoma. Squamous dysplasia is a precancerous lesion for squamous cell carcinoma and Barrett's esophagus is the precancerous lesion for adenocarcinoma. Gastro-esophageal reflux disease (GERD) is the initiation factor for Barrett's esophagus. Cyclooxygenase-2 (COX-2) is a key enzyme in arachidonic metabolism. It appears to play an important role in gastrointestinal carcinogenesis. COX-2 activity may be a potential target for the prevention of cancer progression by selective COX-2 inhibitors, which decrease proliferation and increase apoptosis. Objectives To assess COX-2 expression in premalignant and malignant esophageal epitheliums changes and detect its roles in progression of these lesions. Materials and Methods We analyzed the expression of COX-2 immunohistochemically in 40 esophageal biopsies utilizing the streptavidin-biotin-peroxidase complex method on archival formalin fixed-paraffin embedded blocks. Histopathologically, 17 (42.5%) of cases were non-malignant cases which included GERD, Barrett's esophagus and squamous dysplasia. The malignant cases were 23 (57.5%) squamous cell carcinoma, adenocarcinoma and undifferentiated carcinoma. Results In non-malignant cases 7 (41.2%) out of 17 cases had high COX-2 expression. In squamous cell carcinoma 10 (83.3%) out of 12 cases had high COX-2 expression. The expression of COX-2 was high in all 9 (100%) cases of adenocarcinoma. COX-2 expression is significantly increased (P=0.005 and P=0.0001) in squamous cell carcinoma and adenocarcinoma respectively. There was a significant difference in COX-2 immunoreactivity between malignant and non-malignant lesions (P=0.0003). Conclusion COX-2 is responsible for the progression of esophageal diseases from benign to malignant. We recommend that COX-2 immunohistochemistry should be done routinely for premalignant and malignant esophageal lesions as selective COX-2 inhibitors will be helpful in the treatment. Further studies on molecular and genetic basis of COX-2 expression are needed to unmask its role and relation to progression of esophageal lesions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Cox-2" title="Cox-2">Cox-2</a>, <a href="https://publications.waset.org/abstracts/search?q=Esophageal%20adinocarcinoma" title=" Esophageal adinocarcinoma"> Esophageal adinocarcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Esophageal%20squamous%20cell%20carcinoma" title=" Esophageal squamous cell carcinoma"> Esophageal squamous cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Immunohistochemistry." title=" Immunohistochemistry.

Recent studies have been successful in ROS targeted therapies via antioxidants using mouse models in cancer therapeutics. The present study was designed to scrutinize anticancer activity, antioxidant activity of 5 different extracts of Thymus serpyllum in MDA-MB-231, MCF-7, HepG2, HCT-116, PC3, and A549. Identification of the phytochemicals present in the most active extract of Thymus serpyllum was conducted using gas chromatography coupled with mass spectrophotometry and antioxidant activity was measured by using DPPH radical scavenging and FRAP assay. Anticancer impact of the extract in terms of IC50 was evaluated using MTT cell viability assay. Results revealed that the hexane extract showed the best anticancer activity in HepG2 (Liver Carcinoma Cell Line) with an IC50 value of 23 ± 0.14 µg/ml followed by 25 µg/ml in HCT-116 (Colon Cancer Cell Line), 30 µm/ml in MCF-7 (Breast Cancer Cell Line), 35 µg/ml in MDA-MB-231 (Breast Cancer Cell Line), 57 µg/ml in PC3 (Prostate Cancer Cell Line) and 60 µg/ml in A549 (Lung Carcinoma Cell Line). GC-MS profile of the hexane extract showed the presence of 31 compounds with carvacrol, thymol and thymoquione being the major compounds. Phenolics such as Vitamin E, terpinen-4-ol, borneol and phytol were also identified. Hence, here we present the first report on cytotoxicity of hexane extract of Thymus serpyllum extract in HepG2 cell line with a robust anticancer activity with an IC50 of 23 ± 0.14 µg/ml. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Thymus%20serpyllum%20L." title="Thymus serpyllum L.">Thymus serpyllum L.</a>, <a href="https://publications.waset.org/abstracts/search?q=hexane%20extract" title=" hexane extract"> hexane extract</a>, <a href="https://publications.waset.org/abstracts/search?q=GC-MS%20profile" title=" GC-MS profile"> GC-MS profile</a>, <a href="https://publications.waset.org/abstracts/search?q=antioxidant%20activity" title=" antioxidant activity"> antioxidant activity</a>, <a href="https://publications.waset.org/abstracts/search?q=anticancer%20activity" title=" anticancer activity"> anticancer activity</a>, <a href="https://publications.waset.org/abstracts/search?q=HepG2%20cell%20line" title=" HepG2 cell line"> HepG2 cell line</a> </p> <a href="https://publications.waset.org/abstracts/13474/hexane-extract-of-thymus-serpyllum-l-gc-ms-profile-antioxidant-potential-and-anticancer-impact-on-hepg2-liver-carcinoma-cell-line" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/13474.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">517</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">3857</span> Cytotoxicity of a Short Chain Fatty Acid Histone Deactylase Inhibitor on HCT116 Human Colorectal Carcinoma Cell Line</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20A.%20Kazemi%20Sefat">N.

Histone deacetylase (HDAC) inhibitors induce growth arrest and apoptosis in a variety of human cancer cells. Sodium butyrate (SB) is a short chain fatty acid, belongs to HDAC inhibitors which is released in the colonic lumen as a consequence of fiber fermentation. In this study, we are about to assess the effect of sodium butyrate on HCT116 human colorectal carcinoma cell line. The viability of cells was measured by microscopic morphologic study and MTT assay. After 48 hours, treatments more than 10 mM lead to cell injury in HCT116 by increasing cell granulation and decreasing cell adhesion (p>0.05). After 72 hours, treatments at 10 mM and more lead to significant cell injury (p<0.05). Our results may suggest that the gene expression which is contributed in cell proliferation and apoptosis has been changed under pressure of HDAC inhibition. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=colorectal%20cancer" title="colorectal cancer">colorectal cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=sodium%20butyrate" title=" sodium butyrate"> sodium butyrate</a>, <a href="https://publications.waset.org/abstracts/search?q=cytotoxicity" title=" cytotoxicity"> cytotoxicity</a>, <a href="https://publications.waset.org/abstracts/search?q=MTT" title=" MTT"> MTT</a> </p> <a href="https://publications.waset.org/abstracts/12514/cytotoxicity-of-a-short-chain-fatty-acid-histone-deactylase-inhibitor-on-hct116-human-colorectal-carcinoma-cell-line" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12514.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">361</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">3856</span> RhoA Regulates E-Cadherin Intercellular Junctions in Oral Squamous Carcinoma Cells</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ga-Young%20Lee">Ga-Young Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyun-Man%20Kim"> Hyun-Man Kim</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The modulation of the cell-cell junction is critical in epithelial-mesenchymal transition during tumorigenesis. As RhoA activity is known to be up-regulated to dissociate cell-cell junction by contracting acto-myosin complex in various cancer cells, the present study investigated if RhoA activity was also associated with the disruption of the cell-cell junction of oral cancer cells. We studied SCC-25 cells which are established from oral squamous cell carcinoma if their E-cadherin junction (ECJ) was under control of RhoA. Interestingly, development of ECJ of SCC-25 cells depended on the amount of fibronectin (FN) coated on the culture dishes. Seeded cells promptly aggregated to develop ECJ on the substrates coated with a low amount of FN, whereas they were retarded in the development of ECJ on the substrates coated with a high amount of FN. However, it was an unexpected finding that total RhoA activity was lower in the dissociated cells on the substrates of high FN than in the aggregated cells on the substrates of low FN. Treating the dissociated cells on the substrates of high FN with LPA, a RhoA activator, promoted the development to ECJ. In contrast, treating the aggregated cells on the substrates of low FN with Clostridium botulinum C3, a toxin decreasing RhoA activity, dissociated cells concomitant with the disruption of ECJ. Genetical knockdown of RhoA expression by transfecting RhoA siRNA also down-regulated the development of ECJ in SCC-25 cells. Furthermore, PMA, an activator of protein kinase C (PKC), down-regulated the development of ECJ junction of SCC-25 cells on the substrates coated with low FN. In contrast, GO6976, a PKC inhibitor, up-regulated the development of ECJ of SCC-25 cells with the activation of RhoA on the substrates coated with high FN. In conclusion, in the present study, we demonstrated unexpected results that the activation of RhoA promotes the development of ECJ, whereas the inhibition of RhoA retards the development of ECJ in SCC-25 cells. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=E-cadherin%20junction" title="E-cadherin junction">E-cadherin junction</a>, <a href="https://publications.waset.org/abstracts/search?q=oral%20squamous%20cell%20carcinoma" title=" oral squamous cell carcinoma"> oral squamous cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=PKC" title=" PKC"> PKC</a>, <a href="https://publications.waset.org/abstracts/search?q=RhoA" title=" RhoA"> RhoA</a>, <a href="https://publications.waset.org/abstracts/search?q=SCC-25" title=" SCC-25"> SCC-25</a> </p> <a href="https://publications.waset.org/abstracts/65493/rhoa-regulates-e-cadherin-intercellular-junctions-in-oral-squamous-carcinoma-cells" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65493.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">331</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">3855</span> Automatic Staging and Subtype Determination for Non-Small Cell Lung Carcinoma Using PET Image Texture Analysis</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seyhan%20Kara%C3%A7avu%C5%9F">Seyhan Karaçavuş</a>, <a href="https://publications.waset.org/abstracts/search?q=B%C3%BClent%20Y%C4%B1lmaz"> Bülent Yılmaz</a>, <a href="https://publications.waset.org/abstracts/search?q=%C3%96mer%20Kayaalt%C4%B1"> Ömer Kayaaltı</a>, <a href="https://publications.waset.org/abstracts/search?q=Semra%20%C4%B0%C3%A7er"> Semra İçer</a>, <a href="https://publications.waset.org/abstracts/search?q=Arzu%20Ta%C5%9Fdemir"> Arzu Taşdemir</a>, <a href="https://publications.waset.org/abstracts/search?q=O%C4%9Fuzhan%20Ayy%C4%B1ld%C4%B1z"> Oğuzhan Ayyıldız</a>, <a href="https://publications.waset.org/abstracts/search?q=K%C3%BCbra%20Eset"> Kübra Eset</a>, <a href="https://publications.waset.org/abstracts/search?q=Eser%20Kaya"> Eser Kaya</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this study, our goal was to perform tumor staging and subtype determination automatically using different texture analysis approaches for a very common cancer type, i.e., non-small cell lung carcinoma (NSCLC). Especially, we introduced a texture analysis approach, called Law’s texture filter, to be used in this context for the first time. The 18F-FDG PET images of 42 patients with NSCLC were evaluated. The number of patients for each tumor stage, i.e., I-II, III or IV, was 14. The patients had ~45% adenocarcinoma (ADC) and ~55% squamous cell carcinoma (SqCCs). MATLAB technical computing language was employed in the extraction of 51 features by using first order statistics (FOS), gray-level co-occurrence matrix (GLCM), gray-level run-length matrix (GLRLM), and Laws’ texture filters. The feature selection method employed was the sequential forward selection (SFS). Selected textural features were used in the automatic classification by <em>k</em>-nearest neighbors (<em>k</em>-NN) and support vector machines (SVM). In the automatic classification of tumor stage, the accuracy was approximately 59.5% with <em>k</em>-NN classifier (k=3) and 69% with SVM (with one versus one paradigm), using 5 features. In the automatic classification of tumor subtype, the accuracy was around 92.7% with SVM one vs. one. Texture analysis of FDG-PET images might be used, in addition to metabolic parameters as an objective tool to assess tumor histopathological characteristics and in automatic classification of tumor stage and subtype. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=cancer%20stage" title="cancer stage">cancer stage</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer%20cell%20type" title=" cancer cell type"> cancer cell type</a>, <a href="https://publications.waset.org/abstracts/search?q=non-small%20cell%20lung%20carcinoma" title=" non-small cell lung carcinoma"> non-small cell lung carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=PET" title=" PET"> PET</a>, <a href="https://publications.waset.org/abstracts/search?q=texture%20analysis" title=" texture analysis"> texture analysis</a> </p> <a href="https://publications.waset.org/abstracts/43698/automatic-staging-and-subtype-determination-for-non-small-cell-lung-carcinoma-using-pet-image-texture-analysis" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/43698.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">326</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">3854</span> Initiation of Paraptosis-Like PCD Pathway in Hepatocellular Carcinoma Cell Line by Hep88 mAb through the Binding of Mortalin (HSPA9) and Alpha-Enolase</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Panadda%20Rojpibulstit">Panadda Rojpibulstit</a>, <a href="https://publications.waset.org/abstracts/search?q=Suthathip%20Kittisenachai"> Suthathip Kittisenachai</a>, <a href="https://publications.waset.org/abstracts/search?q=Songchan%20Puthong"> Songchan Puthong</a>, <a href="https://publications.waset.org/abstracts/search?q=Sirikul%20Manochantr"> Sirikul Manochantr</a>, <a href="https://publications.waset.org/abstracts/search?q=Pornpen%20Gamnarai"> Pornpen Gamnarai</a>, <a href="https://publications.waset.org/abstracts/search?q=Sasichai%20Kangsadalampai"> Sasichai Kangsadalampai</a>, <a href="https://publications.waset.org/abstracts/search?q=Sittiruk%20Roytrakul"> Sittiruk Roytrakul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Hepatocellular carcinoma (HCC) is the most primary hepatic cancer worldwide. Nowadays a targeted therapy via monoclonal antibodies (mAbs) specific to tumor-associated antigen is continually developed in HCC treatment. In this regard, after establishing and consequently exploring Hep88 mAb’s tumoricidal effect on hepatocellular carcinoma cell line (HepG2 cell line), the Hep88 mAb’s specific Ag from both membrane and cytoplasmic fractions of HepG2 cell line was identified by 2-D gel electrophoresis and western blot analysis. After in-gel digestion and subsequent analysis by liquid chromatography-mass spectrometry (LC-MS), mortalin (HSPA9) and alpha-enolase were identified. The recombinant proteins specific to Hep88 mAb were cloned and expressed in E.coli BL21 (DE3). Moreover, alteration of HepG2 and Chang liver cell line after being induced by Hep88 mAb for 1-3 days was investigated using a transmission electron microscope. The result demonstrated that Hep88 mAb can bind to the recombinant mortalin (HSPA9) andalpha-enolase. In addition, gradual appearance of mitochondria vacuolization and endoplasmic reticulum dilatation were observed. Taken together, paraptosis-like programmed cell death (PCD) of HepG2 is induced by binding of mortalin (HSPA9) and alpha-enolase to Hep88 mAb. Mortalin depletion by formation of Hep88 mAb-mortalin (HSPA9) complex might initiate transcription-independent of p53-mediated apoptosis. Additionally, Hep88 mAb-alpha-enolase complex might initiate HepG2 cells energy exhaustion by glycolysis pathway obstruction. These results imply that Hep88 mAb might be a promising tool for development of an effective treatment of HCC in the next decade. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hepatocellular%20carcinoma" title="Hepatocellular carcinoma">Hepatocellular carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=Monoclonal%20antibody" title=" Monoclonal antibody"> Monoclonal antibody</a>, <a href="https://publications.waset.org/abstracts/search?q=Paraptosis-like%20program%20cell%20death" title=" Paraptosis-like program cell death"> Paraptosis-like program cell death</a>, <a href="https://publications.waset.org/abstracts/search?q=Transmission%20electron%20microscopy" title=" Transmission electron microscopy"> Transmission electron microscopy</a>, <a href="https://publications.waset.org/abstracts/search?q=mortalin%20%28HSPA9%29" title=" mortalin (HSPA9)"> mortalin (HSPA9)</a>, <a href="https://publications.waset.org/abstracts/search?q=alpha-enolase" title="alpha-enolase">alpha-enolase</a> </p> <a href="https://publications.waset.org/abstracts/4778/initiation-of-paraptosis-like-pcd-pathway-in-hepatocellular-carcinoma-cell-line-by-hep88-mab-through-the-binding-of-mortalin-hspa9-and-alpha-enolase" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/4778.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">361</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">3853</span> Urinary Exosome miR-30c-5p as a Biomarker for Early-Stage Clear Cell Renal Cell Carcinoma</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shangqing%20Song">Shangqing Song</a>, <a href="https://publications.waset.org/abstracts/search?q=Bin%20Xu"> Bin Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yajun%20Cheng"> Yajun Cheng</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhong%20Wang"> Zhong Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> miRNAs derived from exosomes exist in a body fluid such as urine were regarded as potential biomarkers for various human cancers diagnosis and prognosis, as mature miRNAs can be steadily preserved by exosomes. However, its potential value in clear cell renal cell carcinoma (ccRCC) diagnosis and prognosis remains unclear. In the present study, differentially expressed miRNAs from urinal exosomes were identified by next-generation sequencing (NGS) technology. The 16 differentially expressed miRNAs were identified between ccRCC patients and healthy donors. To explore the specific diagnosis biomarker of ccRCC, we validated these urinary exosomes from 70 early-stage renal cancer patients, 30 healthy people and other urinary system cancers, including 30 early-stage prostate cancer patients and 30 early-stage bladder cancer patients by qRT-PCR. The results showed that urinary exosome miR-30c-5p could be stably amplified and meanwhile the expression of miR-30c-5p has no significant difference between other urinary system cancers and healthy control, however, expression level of miR-30c-5p in urinary exosomal of ccRCC patients was lower than healthy people and receiver operation characterization (ROC) curve showed that the area under the curve (AUC) values was 0.8192 (95% confidence interval was 0.7388-0.8996, P= 0.0000). In addition, up-regulating miR-30c-5p expression could inhibit renal cell carcinoma cells growth. Lastly, HSP5A was found as a direct target gene of miR-30c-5p. HSP5A depletion reversed the promoting effect of ccRCC growth casued by miR-30c-5p inhibitor, respectively. In conclusion, this study demonstrated that urinary exosomal miR-30c-5p is readily accessible as diagnosis biomarker of early-stage ccRCC, and miR-30c-5p might modulate the expression of HSPA5, which correlated with the progression of ccRCC. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=clear%20cell%20renal%20cell%20carcinoma" title="clear cell renal cell carcinoma">clear cell renal cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=exosome" title=" exosome"> exosome</a>, <a href="https://publications.waset.org/abstracts/search?q=HSP5A" title=" HSP5A"> HSP5A</a>, <a href="https://publications.waset.org/abstracts/search?q=miR-30c-5p" title=" miR-30c-5p"> miR-30c-5p</a> </p> <a href="https://publications.waset.org/abstracts/93777/urinary-exosome-mir-30c-5p-as-a-biomarker-for-early-stage-clear-cell-renal-cell-carcinoma" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93777.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">267</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">3852</span> Effect of Copper Complexes on Human Colon Carcinoma Cell Line and Human Breast Carcinoma Cell Line</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Katar%C3%ADna%20Ko%C5%88arikov%C3%A1">Katarína Koňariková</a>, <a href="https://publications.waset.org/abstracts/search?q=Georgios%20A.%20Perdikaris"> Georgios A.

Copper(II) and its complexes play an important role as suitable species for antiproliferative tests. Objectives: The central objective of the current study was to investigate the potential in vitro anti-proliferative effects of N-salicylidene-L-glutamato copper (II) complexes and molecular mechanism of apoptosis induced by tested complexes. In our project we tested N-salicylidene-L-glutamato copper (II) complexes ZK1 - [Cu(N-salicylidene-L-glutamato)(H2O)2].H2O; MK0 - ([Cu2(N-sal-D,L-glu)2(isoquinoline)2].2H2O); MK1 - [Cu(N-salicylidene-5-methyl-L-glutamato)(H2O)].H2O; MK3 - transbis(ethanol)tetrakis(imidazol)Cu(II)(2+)bis(N-salicylidene-D,L-glutamato-N,O)-KO:KO´-(imidazol); MK5 - [Cu(N-salicylidene-D,L- glutamato)(2-methylimidazol] at concentration range 0.001-100 µmol/L against human colon carcinoma cell line HT-29 and human breast carcinoma cell line MCF-7. Methods: Viability was assessed by direct counting of 0.4% trypan blue dye-excluding cells after 24, 48 and 72 hour cultivations with or without copper complex and by MTT assay. To analyze the type of cell death and its mechanism induced by our copper complex we used different methods. To distinguish apoptosis from necrosis we used electrophoretic analysis, to study the activity of caspases 8 and 9 – luminometric analysis and caspase activity 3 colorimetric assay. Results: The observed anti-proliferative effect of the copper complexes appeared to be dose-, time- and cell line- dependent. Human colon carcinoma cells HT-29 appeared to be more sensitive to the complex MK0 ([Cu2(N-sal-D,L-glu)2(isoquinoline)2].2H2O) than to ZK1 ([Cu(N-salicylidene-L-glutamato)(H2O)2].H2O) and MK1 ([Cu(N-salicylidene-5-methyl-L-glutamato)(H2O)].H2O)). Human colon carcinoma cells HT-29 appeared to be more sensitive to the complex than human breast carcinoma cells MCF-7. IC50 decreased with time of incubation (24, 48 and 72h) for HT-29, but increased for MCF-7. By electrophoresis we found apoptotic cell death induced by our copper complexes in HT-29 at concentrations 1, 10, 50 and 100 µmol/L after 48h (ZK1) and 72h (MK0, MK1) and in MCF-7 we did not find apoptosis. We also studied molecular mechanism of apoptosis in HT-29 induced by copper complexes. We found active caspase 9 in HT-29 after ZK1 ([Cu(N-salicylidene-L-glutamato)(H2O)2].H2O) and MK1 ([Cu(N-salicylidene-5-methyl-L-glutamato)(H2O)].H2O)) influence and active caspase 8 after MK0 ([Cu2(N-sal-D,L-glu)2(isoquinoline)2].2H2O) influence. Conclusion: Our copper complexes showed cytotoxic activities against human colon carcinoma cells HT-29 and breast cancer cell line MCF-7 in vitro. Apoptosis was activated by mitochondrial pathway (intrinsic pathway) in case of ZK1 [Cu(N-salicylidene-L-glutamato)(H2O)2].H2O; MK1 [Cu(N-salicylidene-5-methyl-L-glutamato)(H2O)].H2O; MK3 - transbis(ethanol)tetrakis(imidazol)Cu(II)(2+)bis(N-salicylidene-D,L-glutamato-N,O)-KO:KO´-(imidazol) and MK5 - [Cu(N-salicylidene-D,L- glutamato)(2-methylimidazol] copper complexes and by death receptors (extrinsic pathway) in case of MK0 [Cu2(N-sal-D,L-glu)2(isoquinoline)2].2H2O copper complex in HT-29. <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=copper%20complex" title=" copper complex"> copper complex</a>, <a href="https://publications.waset.org/abstracts/search?q=cancer" title=" cancer"> cancer</a>, <a href="https://publications.waset.org/abstracts/search?q=carcinoma%20cell%20line" title=" carcinoma cell line"> carcinoma cell line</a> </p> <a href="https://publications.waset.org/abstracts/7794/effect-of-copper-complexes-on-human-colon-carcinoma-cell-line-and-human-breast-carcinoma-cell-line" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/7794.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">293</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">3851</span> Gall Bladder Polyp Identified as Solitary RCC Metastasis 4 Years after Nephrectomy: An Unusual Case Report</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gerard%20Bray">Gerard Bray</a>, <a href="https://publications.waset.org/abstracts/search?q=Arya%20Bahadori"> Arya Bahadori</a>, <a href="https://publications.waset.org/abstracts/search?q=Sachinka%20Ranasinghe"> Sachinka Ranasinghe</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Renal cell carcinoma (RCC) is among the top 10 most common cancers worldwide, where metastatic disease carries a poor prognosis. Herein, we present a 74-year-old male presenting with asymptomatic solitary metachronous metastasis to the gall bladder 4 years following nephrectomy for clear cell RCC. Solitary RCC metastasis to the gall bladder following nephrectomy is rarely reported in the literature and brings with it a clinical conundrum of whether surgical resection or systemic therapy should be utilized. In this case, surgical excision with cholecystectomy was employed without systemic therapy. We, therefore, contribute a rare and interesting case that highlights that metastasectomy of a solitary metastasis can improve survival according to current literature. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=renal%20cell%20carcinoma" title="renal cell carcinoma">renal cell carcinoma</a>, <a href="https://publications.waset.org/abstracts/search?q=gall%20bladder%20metastasis" title=" gall bladder metastasis"> gall bladder metastasis</a>, <a href="https://publications.waset.org/abstracts/search?q=solitary%20metastasectomy" title=" solitary metastasectomy"> solitary metastasectomy</a>, <a href="https://publications.waset.org/abstracts/search?q=metachronous" title=" metachronous"> metachronous</a> </p> <a href="https://publications.waset.org/abstracts/145137/gall-bladder-polyp-identified-as-solitary-rcc-metastasis-4-years-after-nephrectomy-an-unusual-case-report" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/145137.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">173</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">3850</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 biochemical and radiographic evaluation of ROD and its subtypes was performed, and then all patients underwent bone biopsy and histopathological study, and finally, the diagnostic value of the noninvasive methods was assessed. Results: The mean age of patients was 58.9 ± 11.7 years, and 27 cases (54.0%) were female. 38 (76.0%) of RCC patients with ESRD had ROD, and 12 patients (24.0%) had no evidence of bone disorders. The sensitivity, specificity, positive and predictive values and accuracy of the noninvasive methods for the diagnosis of ROD were 92%, 82%, 95%, 75% and 90%, respectively. Conclusion: This study showed that the frequency of ROD in RCC patients with ESRD in northern Iran was high and the biochemical and radiographic markers have a high diagnostic value for ROD as well as histopathological assessment. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=renal%20cell%20carcinoma" title="renal cell carcinoma">renal
