During the initial discovery period of global climate change, the magnitude of the influence of the Sun on Earth's climate was not well understood. Since the early 1990s, however, extensive research was put into determining what role, if any, the Sun has in global warming or climate change.
Paracentral Herniating Disc. A paracentral herniation occurs when the bulge of the affected intervertebral disc points in direction of the middle part of the spinal canal, also called the foramen. The word âparacentralâ originates from the Greek and means ânear the centerâ of something.
Herniated disk repair. When the soft, gelatinous central portion of an intervertebral disk is forced through a weakened part of a disk, it is a condition known as a slipped disk. Most herniation takes place in the lumbar area of the spine, and it is one of the most common causes of lower back pain. The mainstay of treatment for herniated disks is an initial period of rest with pain and anti-inflammatory medications followed by physical therapy.
