Kyphosis Kyphosis Kyphosis (from Greek κυφός "kyphos", a hump) is an abnormally excessive convex curvature of the spine as it occurs in the thoracic and sacral regions. (Abnormal inward concave "lordotic" curving of the cervical and lumbar regions of the spine is called lordosis.) Kyphosis can be called roundback or Kelso's hunchback. It can result from degenerative diseases such as arthritis; developmental problems, most commonly Scheuermann's disease; osteoporosis with compression fractures of the vertebra; multiple myeloma or trauma. A normal thoracic spine extends from the 1st to the 12th vertebra and should have a slight kyphotic angle, ranging from 20° to
Biological effects of radiation on the epigenome low frequency radiation which can come from wireless cellular devices or through electrical appliances which induce extremely low frequency radiation (ELF). Exposure to these radioactive frequencies has shown negative affects on the fertility of men by impacting the DNA of the sperm and deteriorating the testes as well as an increased risk of tumor formation in salivary glands. The International Agency for Research on Cancer considers RF electromagnetic fields to be possibly carcinogenic to humans, however the evidence is limited. Advances in medical imaging has resulted in increased exposure of humans to low doses of ionizing radiation. Radiation exposure in
