Bioresorbable polymers and biocorrodible metals are the latest developments in biodegradable materials used in interventional cardiology for the mechanical treatment of coronary atherosclerosis. Poly-L-lactic acid is the most frequently used bioresorbable polymer and initial evidence of feasibility, efficacy and clinical safety following deployment of polymer-based platforms was gained after co...

background: the most efficient application of ionizing radiation is serving medical purposes and using this radiation has caused people to learn that artificial sources of radiation exposure among these resources can be of highest exposure rate.   objective: the present study is aimed at initially establishing a baseline for local-reference dose level in mazandaran, iran in 12 projections of th...

introduction dose calculation of tumor and surrounding tissues is essential during prostate brachytherapy. three radioisotopes, namely, 125i, 103pd, and 131cs, are extensively used in this method. in this study, we aimed to calculate the received doses by the prostate and critical organs using the aforementioned radioactive seeds and to investigate the effect of scattering contribution for the ...

PURPOSE We evaluated the chemopreventive effect of statins on colon cancer in patients with chronic obstructive pulmonary disease (COPD) and identified the statin exerting the strongest chemopreventive effect. METHODS Using the National Health Insurance Research Database, we identified patients who received a COPD diagnosis in Taiwan between January 1, 2001, and December 31, 2012, and include...

although splenic metastasis is fairly common in disseminated cancer, solitary splenic metastasis in the absence of diffuse dissemination is rare. we report a case of 44 year-old man who developed isolated splenic metastasis of colon cancer. the patient had undergone right sided hemicolectomy for colon cancer in 1988. in 2001, he underwent reoperation because of local recurrence of tumor in the ...

backgrounds and objectives: today we are witnessed a growing number of minimally invasive surgical techniques for different diseases. laparoscopic colon surgery as a minimally invasive surgery is currently growing in treatment of malignancies after proving his place in the treatment of benign diseases. we compare in this study results of laparoscopic colorectal surgery with open surgery. method...

introduction: as a physical treatment, electrochemical therapy (echt) has provided an effective and useful  approach  for  treating  localized  tumors.  the  chemical  changes  due  to  a  direct  electric  current  destroy  the  tumor. this study evaluates the effect of electrical dose and polarity on the efficacy of the treatment of a  colon tumor model.  materials and methods: in order to in...

the aim of this paper is to introduce new methods of colorectal and anus surgeries. it is not a comprehensive paper and just is a summary of issues related to colon surgeries due to intestinal inflammatory diseases (ulcerative colitis and crohn's disease), and anus cancer. ulcerative colitis usually initiates from rectum and then develops upward to colon. there are three methods of surgery...

Introduction: Colon adenocarcinoma is one of the foremost causes of cancer mortality. Oral metastasis of colon adenocarcinoma is, however, rare and indicates an end-stage disease process.   Case Report: We report a case of a 69-year-old female with a gingival mass diagnosed with colon adenocarcinoma and liver metastasis after one year. A swelli...
