Background:The incidence rate of head and neck cancer in the world is about 560,000 new cases a year. Larynx cancer is the most common malignancy in head and neck in Iran. The most common head and neck carcinoma is the malignancy of squamous epithelial cells. This study was conducted to determine the survival rate of patients undergoing nonsurgical treatment methods for larynge...
Background: The aim of this study was to investigate the efficacy and safety of metronomic capecitabine chemotherapy in pretreated elderly patients with advanced gastric carsonoma. Patients and Methods: Eligible patients were treated with capecitabine at a fixed dose of 1000mg daily until disease progression or toxicity. Endpoints were overall response rate, safety, progression-free survival...

Their age range was 39-81 years, they were all three st...
Background: Multiple sclerosis (MS) is an inflammatory disease of the central nervous system with multifocal areas of demyelination. Despite an increased understanding of the mechanisms causing MS, immunological factors that indicate disease activity are only starting to be discovered. Chronic brain inflammation is often associated with an increase in production of IgG in the CSF as determined ...
to evaluate the effect of adding neoadjuvant chemotherapy to surgery and radiation therapy for locally advanced resectable oral cavity squamous cell carcinoma, 24 patients with t3 or t4a oral cavity squamous cell carcinoma were randomly assigned to surgery alone or docetaxel, cisplatin, and 5-fu (tpf) induction chemotherapy followed by surgery. all patients were planned to receive chemoradiothe...
Introduction: The development and progress of computerized technologies has revolutionized radiology with digital imaging. The aim of this study is to compare Digital Radiography(DR) and Temporal Digital Subtraction (TDS)in detection of dentinal caries progression.

Background & Objective: Clinically Chronic Allograft Dysfunction (CAD) is characterized by a progressive decline in Glomerular Filtration Rate (GFR) over time, the pattern of disease progression determined by the five-stage model. In this paper, we used Erlang and Hypo-exponential distributions as Phase- Type distributions to describe hazard of kidney failure at over time in RTR with CAD. Me...
Introduction: Epigenetics involves the study of heritable changes in the regulation of gene activity and expression that are not dependent on gene sequence. Main mechanisms of epigenetic modifications are DNA methylation, Histone modification and Nucleosome positioning. Several studies have shown that these modifications are related to cancer initiation, progression or tumor metastasis. In cont...
