BCC and Childhood Low Dose Radiation
Skin cancer is a late complication of ionizing radiation. Two skin neoplasms prominent Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC) are the most famous complications of radiotherapy. Basal Cell Carcinoma (BCC) is the most common human malignant neoplasm. Many genetic and environmental factors are involved in its onset. BCC is observed in sunexposed areas of skin. Some patients w...
متن کاملLow dose radiation prevents doxorubicin-induced cardiotoxicity
This study aimed to develop a novel and non-invasive approach, low-dose radiation (LDR, 75 mGy X-rays), to prevent doxorubicin (DOX)-induced cardiotoxicity. BALB/c mice were randomly divided into five groups, Control, LDR (a single exposure), Sham (treated same as LDR group except for irradiation), DOX (a single intraperitoneal injection of DOX at 7.5 mg/kg), and LDR/DOX (received LDR and 72 h ...
متن کاملLow-dose radiation exposure and carcinogenesis.
Absorption of energy from ionizing radiation by the genetic material in the cell leads to damage to DNA, which in turn leads to cell death, chromosome aberrations and gene mutations. While early or deterministic effects result from organ and tissue damage caused by cell killing, latter two are considered to be involved in the initial events that lead to the development of cancer. Epidemiologica...
متن کاملAdaption By Low Dose Radiation Exposure
h The procedures and dose limitations used for radiation protection in the nuclear industry are founded on the assumption that risk is directly proportional to dose, without a threshold. Based on this idea that any dose, no matter how small, will increase risk, radiation protection regulations generally attempt to reduce any exposure to “as low as reasonably achievable” (ALARA). We know however...
متن کاملUltra-Low Radiation Dose Renal CT Examinations
These efforts include the development of customized protocols that take into account the patient’s age, body mass and clinical indication. This allows for lower dose scan parameters and targeted scanning to cover only the region of interest and thereby limit oversampling. In addition, new iterative image reconstruction techniques can improve image quality on low dose, higher noise CT scans. As ...
