Introdution: Today, the Advantages of radiation therapy by charged particles is indicated for the treatment of cancerous. During the passing of proton beam in the body tissues, secondary particles produce, which penetrate to the body healthy tissues and cause damage. The aim of this research was calculating the Spread out Bragg Peak for covering the breast cancer and investigating arrived dose ...
Cancer stem cells are believed to be responsible for the cancer-initiating step and resistance to chemotherapy drugs. Studies have shown that cancer stem cells are silent and have no metabolic activity. The main reasons behind tumors resistant to therapies are lack of activity of cancer stem cells and division of cancer cells. This cell population, like normal stem cells, is capable of self-ren...

Since prevention programs demand to be held in this regard in childhood and adolescence, this study aimed to determine the Knowledge, attitude, and performance of secondary school female students towards skin cancer and sun protection behaviors in Yazd. ...
conclusions the expression of recombinant calprotectin, as an effective protein, can help in diagnosis or treatment of inflammatory and cancer processes in the future. furthermore, ca2+ induced a partial change in secondary and tertiary structure of calprotectin subunits and this change is probably necessary for protein dimerization. results interaction of s100a8 and s100a9 in the presence of c...

BACKGROUND Thyroid cancer is one of the most common secondary cancers after treatment of malignancy in childhood or adolescence. Thyroid gland is very sensitive to the carcinogenic effect of ionizing radiation, especially in children. Imbalance between pro- and anti-oxidant factors may play a role in thyroid carcinogenesis. Our study aimed to assess the relationship between genetic variability ...
Cancer is a genetic condition. Some cancers are inherited, but most are caused by mutations in somatic cells. The cause of these mutations is inherent error in the transcription of DNA or exposure to carcinogens. Malignant melanoma is the most serious type of skin cancer which develops from pigment-containing cells known as melanocytes. The most potent risk factors for melanoma is the presence ...
PURPOSE Secondary lymphedema is a frequent complication of breast cancer associated with surgery, chemotherapy, or radiation following breast cancer treatment. The potential contribution of genetic susceptibility to risk of developing secondary lymphedema following surgical trauma, radiation, and other tissue insults has not been studied. EXPERIMENTAL DESIGN To determine whether women with br...
