Cs adsorption by Mn‒Fe-based Prussian blue analogs formed in agarose gel
The Fukushima nuclear accident triggered a massive release of radioactive cesium (Cs) isotopes into the environment and generated a large amount of contaminated water. Because Cs isotopes pose serious threats to the environment (particularly the aquatic environment),
Effectiveness of infrared tympanic thermometry during physical activity in the heat at a solar radiation of 500 W/m2 or less
Exposure to high solar radiation in the heat poses a thermoregulatory challenge and increased risks of exertional heat-related illness in workers and exercising individuals. Core temperature monitoring is important during physical activity in the heat to prevent
Does tangential radiation for breast cancer cover internal mammary nodes?
Breast cancer is one of the most common cancers in women in the United States. Radiation is a very commonly used treatment modality for breast cancer: it is offered to nearly all patients after lumpectomy (removal of
What do patients and healthcare professionals “tweet” about brachytherapy?
Many patients post on Twitter about their healthcare experiences. Patients with cancer are especially active on Twitter, and studies have found that sharing experiences online can reduce feelings of isolation. Healthcare professionals also frequently post on Twitter.
Combining radiation with a PI3K/MTOR inhibitor
Patients with HPV-negative head and neck cancer (HNSCC) carry a poor prognosis despite optimal treatment with chemoradiation, with a 5 year survival of less than 50%. The future for this disease must lie in further escalation of
Screening sunscreens: protecting the biomechanical barrier of skin from ultraviolet radiation damage
The uppermost layer of human skin, known as the stratum corneum (SC), is the most important physical barrier between the human body and the environment and plays a surprisingly acute role in the mechanical function of full
Why is radiation treatment more effective for cancers caused by HPV?
Human papilloma virus (HPV) is the most common sexually transmitted infection in the United States and can lead to cancers in the affected organ such as the cervix. In the last 15 years, the rise in prevalence
Visual side-effects in radiation treatment of meningioma
Meningioma is one of the most prevalent tumors in the brain. This kind of tumor arises from the natural layers covering the brain; so it is expected to see this tumor in different locations of brain. There
Three dimensional quality assurance protocol for thoracic and genitourinary radiation therapy
After cancer diagnosis one treatment option is the use of external radiation. As the radiation traverses the patient it deposits most of its energy in the tumor, which causes irreparable damage to the cancer cells. One type
Hormetic use of stress in gerontological interventions requires a cautious approach
Hormesis is a biphasic dose-response pattern in which the response at low doses is opposite to that at higher doses. According to the hormesis concept, a small dose of a potentially harmful agent can exert a beneficial
Side effects of radiation therapy: Why me?
Most lung cancers are treated with radiation therapy, often in high doses. Although these treatments are absolutely required to prolong life (by killing the tumor or slowing its growth), radiation treatment can have negative side effects that
Decreased radiation exposure with a safety training program
The importance of limiting radiation exposure among healthcare workers and patients is of utmost importance. According to the National Council on Radiation and Standards the recommended maximum annual dose of radiation to the whole body is 5,000
Pre-radiation lymphocyte harvesting and post-radiation reinfusion in patients with newly diagnosed high grade gliomas
In people diagnosed with malignant brain tumors, the prescribed treatment is often radiation and chemotherapy; however, these treatments severely affect the immune system, increasing the chance of early death. Radiation in particular has been known to cause
Kidney disease after radiation exposure
Radiation exposure on earth is usually at a very low dose. Diagnostic x-rays are essential for modern medical care and pose little or no radiation risk. High dose radiation is much less common than diagnostic x-ray, but
What does a guardian protect genomic DNA from?
Living organisms can achieve their propagation through copying (replicating) the genetic information, coded in DNA sequence, and dividing them to each daughter cell. DNA sequence is a basic element and its conservation is essential for individual life
