1. Argon Plasma Coagulation in Radiation-induced Proctitis
Abstract Background Argon plasma coagulation (APC) is a non-tactile ablative therapy that helps to stop rectal bleeding in patients who have developed actinic proctitis after exposure to radiotherapy. This approach seems to be more effective than medications or surgical procedures. Objective To review the literature to verify the effectiveness of APC in th

2. Evaluation of HIF-1α and VEGF-A expression in radiation-induced cystitis: A case-control study
ABSTRACT The standard treatment for locally advanced cervical cancer (CC) is chemoradiotherapy. Once the bladder receives part of the radiation, a typical inflammatory condition that configures radiation-induced cystitis may develop. Chronic radiation-induced cystitis is commonly characterized by the bladder new submucosal vascularization, which is typically

3. Identification of novel mutations of Insulin Receptor Substrate 1 (IRS1) in tumor samples of non-small cell lung cancer (NSCLC): Implications for aberrant insulin signaling in development of cancer
Abstract Lung cancer is the leading cause of cancer-related death, and NSCLC constitutes nearly 85%–90% of all cases. The IRS proteins function as adaptors and transmit signals from multiple receptors. Upon binding of insulin to the insulin receptor (IR), IRS1 is phosphorylated at several YXXM motifs creating docking sites for the binding of PI3Kp85, which

4. Absorbed doses in salivary and thyroid glands from panoramic radiography and cone beam computed tomography
Abstract Introduction: Panoramic radiography and cone beam computed tomography (CBCT) are very important in the diagnosis of oral diseases, however patients are exposed to the risk of ionizing radiation. This paper describes our study aimed at comparing absorbed doses in the salivary glands and thyroid due to panoramic radiography and CBCT and estimating ra

5. Radiotherapy modulates expression of EGFR, ERCC1 and p53 in cervical cancer
Cervical cancer is a public health problem and the molecular mechanisms underlying radioresistance are still poorly understood. Here, we evaluated the modulation of key molecules involved in cell proliferation, cell cycle and DNA repair in cervical cancer cell lines (CASKI and C33A) and in malignant tissues biopsied from 10 patients before and after radiothe

6. Radiation exposure and thyroid cancer: a review
ABSTRACT The association between radiation exposure and the occurrence of thyroid cancer has been well documented, and the two main risk factors for the development of a thyroid cancer are the radiation dose delivered to the thyroid gland and the age at exposure. The risk increases after exposure to a mean dose of more than 0.05-0.1 Gy (50-100mGy). The risk

7. The Role of Apollon Gene Silencing on Viablity and Radiosensitivity of Cervical Cancer Hela Cells
Cervical cancer is the second common cause of cancer deaths in women worldwide. Radioresistancy of cancer is a principal cause of treatment impairing. Inhibitor of apoptosis proteins (IAPs) widely block apoptosis against apoptotic stimuli, including current chemo- and radiation therapies. Apollon, a membrane of IAP, can support cells against apoptosis and is

8. Ionizing radiation-induced DNA injury and damage detection in patients with breast cancer
Abstract Breast cancer is the most common malignancy in women. Radiotherapy is frequently used in patients with breast cancer, but some patients may be more susceptible to ionizing radiation, and increased exposure to radiation sources may be associated to radiation adverse events. This susceptibility may be related to deficiencies in DNA repair mechanisms t

9. A Novel Approach for the Treatment of Radiation-Induced Hemorrhagic Cystitis with the GreenLight™ XPS Laser
ABSTRACT Introduction: The treatment of pelvic malignancies with radiotherapy can develop severe sequelae, especially radiation-induced hemorrhagic cystitis. It is a progressive disease that can lead to the need for blood transfusion, hospitalizations, and surgical interventions. This tends to affect the quality of life of

10. Effect of fractionated radiotherapy on the parotid gland: an experimental study in Brazilian minipigs
INTRODUCTION: Radiotherapy (RT) of head and neck neoplasms often damages the salivary glands. AIM: To examine the pattern of morphologic changes resulting from RT of the head and neck region in minipig parotid glands in a clinical and experimental research setting. METHODS: Twelve 18-month-old male Brazilian minipigs weighing 30-40 kg were selected. Eight mi
