Bone pain, Bone metastases, Health resource utilization, Radiation to bone, Skeletal-related eventHRU increased following radiation to bone across all countries studied. Agents that prevent severe pain and delay the need for radiation have the potential to reduce the burden imposed on healthcare ...
1.Radioactivity occurs naturally. The main sources are in space, rocks, soil, water and even the human body itself.
health and lifestyle factors. Male infertility is likely to be affected by the intense exposure to heat and extreme exposure to pesticides, radiations, radioactivity and other hazardous substances. We are surrounded by several types of ionizing and non-ionizing radiation...
Sunlight and vitamin D for bone health and prevention of autoimmune diseases, cancers, and cardiovascular disease Most humans depend on sun exposure to satisfy their requirements for vitamin D. Solar ultraviolet B photons are absorbed by 7-dehydrocholesterol in the ski... Holick,F Michael - 《Ame...
Radiation exposure is measured primarily in Rem (in the US) and the Sievert (SI unit), and is a measure of the radioactive dose absorbed relative to its possible health effects on the body. This is called the “equivalent dose,” and is weighted to account for the fact that the same ...
It produces less damage to the skin at the entry port, is absorbed less in bone, and is scattered less, thus reducing the exposure to tissues outside the x-ray beam. Low-energy x-rays that do not penetrate are used for treatment of superficial skin lesions. Internal Radiation Therapy (...
Radiation-induced bystander effect (RIBE) has important implications for secondary cancer risk assessment during cancer radiotherapy, but the defense and self-protective mechanisms of bystander normal cells are still largely unclear. The... Y Xie,S Ye,J Zhang,... - 《Sci Rep》 被引量: 4发表:...
Radiation can occur from unstable atoms that undergo radioactive decay, or it can be created by machines (eg, diagnostic radiographic/fluoroscopic machines, computed tomographic machines, medical linear accelerator [LINAC], and bone mineral densitometers). Radiation travels from its source in the form...
Evidence from these clinical trials was included in a systematic review conducted by the Agency for Healthcare Research and Quality (AHRQ) to inform the guideline update. “The use of conformal radiation and dose escalation for symptomatic bone metastases has moved from the experimental...
Stereotactic radiotherapy has demonstrated its potential in several indications and treatment sites, e.g., brain and lung [1]. High precision, limited toxicity and effective local control are hallmarks of this type of external beam radiotherapy [2]. Painful uncomplicated bone metastases have long bee...
