در این تحقیق، نوع مرگ سلولی ناشی از تاثیر پلاتین در رده سلولی mcf-7 که یک رده سرطان پستان انسان است، توسط روش میکروسکوپ الکترونی انتقالی تعیین شد.سلولهای mcf-7 در دو گروه شاهد و آزمایشی کشت داده شدند. گروه آزمایشی با دوز 1 میکرومول از داروی سیس پلاتین و گروه شاهد با محلول نرمال سالین تیمار شد. 48 ساعت بعد، سلولهای چسبیده و کنده شده در دو گروه شاهد و آزمایشی جمع آوری و جهت مطالعه در میکر...
The development of secondary malignancy (SM) is the most worrisome long-term complication of childhood cancer. Acute myeloid leukemia is the most prevalent neoplasm that occurs after treatment with alkylating agents and topoisomerase II inhibitors. Pleuropulmonary blastoma (PPB) is a rare lung neoplasm in children. Type II and type III of this cancer are markedly aggressive and have a recurrent...
Unlike proton therapy, conventional radiation therapy directs X-rays not only at the tumor but also unavoidably at nearby healthy tissue. Protons deliver radiation to tumor tissue while the healthy structures will be spared during proton therapy. When protons travel through matter, secondary particles like neutrons and photons are produced. It is believed that the secondary dose can lead to sec...
Radiotherapy for prostate cancer is associated with an increased incidence of secondary bladder cancer (BC). We investigated the incidence, clinicopathological characteristics, and prognosis of BC after radiotherapy, surgical therapy, and primary androgen-deprivation therapy (ADT) for prostate cancer. This study included 1,334 Japanese patients with prostate cancer treated with radiotherapy (n=...
Background: Gold nanoparticles are emerging as promising agents for cancer therapy and are being investigated as drug carriers, photothermal agents, contrast agents and radiosensitisers.Objective: The aim of this study is to understand characteristics of secondary electrons generated from interaction of gold nanoparticles GNPs with x-rays as a function of nanoparticle size and beam energy and ...
Background and Objectives: Tumor-infiltrating regulatory T (TI-Treg) cells perform the significant function in cancer immune escape. In this study, the third generation CAR construct was designed against human CD25 antigen, the significant cell surface biomarker of TI-Tregs. Methods: Initially, the construct of anti-CD25 CAR was designed. Using RNAfold web server, the RNA secondary structure wa...
Patients with cancer have a high risk of deep vein thrombosis and pulmonary embolism, as well developing atrial fibrillation (AF) secondary to antineoplastic treatment. These events poor prognosis depend on factors related the tumor ongoing therapy. They are usually elevated during first 6 months […] How Anticoagulate Heart Failure Cancer?
background: angiosarcoma can develop in all parts of the body containing blood vessels, including breast. statistically, less than 10% of all angiosarcomas originate in the breast. angiosarcoma accounts for less than 0.05% of breast primary cancers. primary angiosarcoma develops without a history of treatment for breast cancer, whereas secondary angiosarcoma develops in patients who have alread...
BACKGROUND Despite impressive advances in our understanding of the biology of novel influenza A(H1N1) virus, little is as yet known about its transmission efficiency in close contact places such as households, schools, and workplaces. These are widely believed to be key in supporting propagating spread, and it is therefore of importance to assess the transmission levels of the virus in such set...
Multiple sclerosis is associated with a decreased risk of cancer. Smoking is a risk factor both for multiple sclerosis and lung cancer. We performed a meta-analysis on studies of cancer frequency in multiple sclerosis. Surprisingly, we found that the risk of lung cancer is reduced in multiple sclerosis [odds ratio 0.67 (95% confidence interval 0.59-0.76) P < 0.00001]. Since this does not appear...
