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

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

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
