    Convenient medical diagnostics and treatments can replace conventional healthcare procedures because of their fast and profitable applications with reduced infection risk. Meanwhile, early diagnosis of cancer is a leading research subject due to the high fatality rate of the disease and being a vital precursor in the treatment effectiveness. Electrochemical-based micro-biosensors are the best candidates for measuring particular biomarker concentrations in body fluids. To address this need, we used a simple fabrication approach to develop an effective immunosensor for the early detection of cancer, in particular prostate cancer. The carbon fibers, obtained from the electrospinning technique,... 

    An Algorithm for Analyzing the Spatial Distribution of the Evolutionary Development Processes

    , M.Sc. Thesis Sharif University of Technology Moradi, Davoud (Author) ; Foroughmand-Araabi, Mohammad Hadi (Supervisor)
    Evolutionary processes are the process of change in one or more physical and heritable characteristics that result from the occurrence of genetic changes (beneficial, harmful, or neutral) over time, and ultimately from generation to generation, depending on natural selection. Cancer is a genetic disease that occurs as a result of an evolutionary process by the somatic cells and examining the spatial characteristics of cancer can help understanding it. It is also important to examine the spatial configuration of cells considering their access to limiting factors such as nutrients and adequate space. In addition, paying attention to the gene expression, individually and collectively, will help... 

    Designing and Fabrication of Microfluidic Biosensor by DNA-Directed Immobilization

    , Ph.D. Dissertation Sharif University of Technology Esmaeili, Elaheh (Author) ; Vossoughi, Manouchehr (Supervisor) ; Soleimani, Masoud (Supervisor) ; Shamloo, Amir (Supervisor)
    The present study is aimed at the development of a novel approach based on the magnetically improvement of DNA-directed immobilization to prepare a highly efficient sensor for prostate diagnosis. The novelty of this work is in the use of antibody conjugated magnetic nanoparticles via DDI. DNA-modified magnetic nanoparticles are added in solution to capture DNA-conjugated, fluorescently-labeled immunocomplexes formed in solution free of steric constraints. The DDI-based nanoconstructs are then concentrated and immobilized using a magnetic field. Compared to a process in which the immunocomplex directly forms on the sensing surface, the proposed approach provides higher mass transfer and lower... 

    An Investigation on the Parameters Affecting Electrochemical Biosensors Performance to Detect Prostate Cancer

    , M.Sc. Thesis Sharif University of Technology Saghafi, Mohammad Javad (Author) ; Abdekhodaie, Mohammad Jafar (Supervisor)
    Early detection of prostate cancer using biosensors has been a subject of research for nearly two decades due to its critical importance. The timing of detection plays a crucial role in determining treatment success rates. However, a significant limitation of these studies has been the cost and limited sensitivity of the sensors. In this research, various treatments used in biosensors were compared and necessary parameters to develop a sensitive, low-cost sensor have been subject of optimization. For this reason, we used pencil graphite and graphite sheet electrodes, both of which have potential for low-cost production on a large scale. Additionally, we tested graphene oxide, amine-treated... 

    Fuzzy Control of Percutaneous Needle Using Ultrasound Imaging-Based
    Trajectory Planning

    , M.Sc. Thesis Sharif University of Technology Kariminik, Mitra (Author) ; Jahed, Mehran (Supervisor)
    Subcutaneous needle insertion is one of the key methods of limited invasive surgery in medical diagnosis and treatment. However, errors in needle targeting can reduce the effectiveness of such efforts. One of the main factors of errors is due to the human guidance of the needle, which many researches have approached in recent years, and among the suggested solutions is the use of automatic or semi-automatic assist systems. Considering the treatment of prostate cancer by brachytherapy method, this research has developed a semi-automatic physician assistance system using navigation based on the potential field method and ultrasound images of the needle location, and sliding mode fuzzy... 

    A novel ensemble strategy for classification of prostate cancer protein mass spectra

    , Article 29th Annual International Conference of IEEE-EMBS, Engineering in Medicine and Biology Society, EMBC'07, Lyon, 23 August 2007 through 26 August 2007 ; 2007 , Pages 5987-5990 ; 05891019 (ISSN) ; 1424407885 (ISBN); 9781424407880 (ISBN) Assareh, A ; Moradi, M. H ; Esmaeili, V ; Sharif University of Technology
    Protein mass spectra pattern recognition is a new forum in which many machine learning algorithms have been conducted to enhance the chance of early cancer diagnosis. The high-dimensionality-small-sample (HDSS) problem of cancer proteomic datasets still requires more sophisticated approaches to improve the classification accuracy. In this study we present a simple ensemble strategy based on measuring the generalizing capability of different subsets of training data and apply it in making final decision. Using a limited number of biomarkers along with 5 classification algorithms, the proposed method achieved a promising performance over a well-known prostate cancer mass spectroscopy dataset....

    Breast and prostate cancers are common types of cancers with various strategies, such as chemotherapy and radiotherapy, for their therapy. Since these methods have undesired side effects and poor target affinity, neoteric strategies—known as aptamer-based smart drug delivery systems (SDDSs)—have been developed in recent years to overcome the obstacles of current treatment, and investigated for a clinical trial. The high affinity and versatility of aptamers for binding to the corresponding targets make them highly noticeable agents in the drug delivery domains. In addition to their exceptional benefits, aptamers are able to overcome tumor resistance because of their high selectivity and low... 

    Using Body Fluids for Early Prostate Cancer Detection

    , M.Sc. Thesis Sharif University of Technology Jalali Dowlatshahi, Sayeh (Author) ; Abdekhodaie, Mohammad Jafar (Supervisor)
    Today, despite the notable progress in diagnostics and therapeutics, cancer remains the second cause of death worldwide. This rather high mortality rate is often attributed to cancers diagnosed at late stages, including prostate cancer. Among the techniques approved for prostate cancer diagnosis, total or free prostate-specific antigen screening using blood serum samples is the sole method able to detect prostate cancer at an early stage. This test has led to a significant decrease in prostate cancer-related deaths. Nonetheless, it possesses several drawbacks, such as the complex, costly, and time-consuming conventional methods utilized in clinical laboratories to assess the concentration of...

    Prostate Cancer has become one of the deadliest cancers among males in many nations. Pathologists use various approaches for the detection and the staging of prostate cancer. Microscopic inspection of biopsy tissues is the most accurate approach among them. The Gleason grading system is used to evaluate the stage of Prostate Cancer using prostate biopsy samples. The task of assigning a grade to each region in a tissue is a time-consuming task. Furthermore, this task often has several challenges since it has considerable inter-observer variability even among expert pathologists. In this paper, we propose an automatic method for this task using a deep learningbased approach. For this purpose,... 

    Optimization of the Dose Distribution in the Brachytherapy Using the Genetic Algorithm in Order to Increase the Absorbed Dose in the Cancer Tumor and to Reduce It in the Healthy Tissues

    , M.Sc. Thesis Sharif University of Technology Naderi, Hossein (Author) ; Hosseini, Abolfazl (Supervisor)
    Prostate cancer is the second most common cancer in men and the fourth most common cancer in all cancers. Cancer treatment is done according to the type of cancer and its diagnosis stage with different treatment methods and plans. Brachytherapy is one of the most common methods of cancer treatment along with teletherapy, surgery and chemotherapy. In this method, the source of radiation is located near or inside the tumor, and its advantage is to achieve a lower dose ratio of healthy tissue to the tumor is lower compared to teletherapy. One of the challenges in brachytherapy is to prescribe the appropriate treatment plan for the patient, so that the maximum dose of sources reaches the...

    Importance: Cancer and other noncommunicable diseases (NCDs) are now widely recognized as a threat to global development. The latest United Nations high-level meeting on NCDs reaffirmed this observation and also highlighted the slow progress in meeting the 2011 Political Declaration on the Prevention and Control of Noncommunicable Diseases and the third Sustainable Development Goal. Lack of situational analyses, priority setting, and budgeting have been identified as major obstacles in achieving these goals. All of these have in common that they require information on the local cancer epidemiology. The Global Burden of Disease (GBD) study is uniquely poised to provide these crucial data....

    Prostate cancer (PCa), the second most malignant neoplasm in men, is also the fifth leading cause of cancer-related deaths in men globally. Unfortunately, this malignancy remains largely asymptomatic until late-stage emergence when treatment is limited due to the lack of effective metastatic PCa therapeutics. Due to these limitations, early PCa detection through prostate-specific antigen (PSA) screening has become increasingly important, resulting in a more than 50% decrease in mortality. Conventional assays for PSA detection, such as enzyme-linked immunosorbent assay (ELISA), are labor intensive, relatively expensive, operator-dependent and do not provide adequate sensitivity....

    Cancer has long been a leading cause of death. The primary tumor, however, is not the main cause of death in more than 90% of cases. It is the complex process of metastasis that makes cancer deadly. The invasion metastasis cascade is the multi-step biological process of cancer cell dissemination to distant organ sites and adaptation to the new microenvironment site. Unraveling the metastasis process can provide great insight into cancer death prevention or even treatment. Microfluidics is a promising platform, that provides a wide range of applications in metastasis-related investigations. Cell culture microfluidic technologies for in vitro modeling of cancer tissues with fluid flow and the...
