Idiopathic hypertrophic spinal pachymeningitis: a case report and review of literature.

Purpose: To report an unusual case of idiopathic hypertrophic spinal pachymeningitis (IHSP) with a review of relevant literature and to discuss the etiology, clinical features, imaging, treatment and prognosis of IHSP.

Methods: The case of a 44-year-old woman is reported. MEDLINE was used to search relevant literatures written in English since 2004.

The Golgi Apparatus: Panel Point of Cytosolic Ca(2+) Regulation.

The Golgi apparatus (GA), an intermediate organelle of the cell inner membrane system, plays a key role in protein glycosylation and secretion. In recent years, this organelle has been found to act as a vital intracellular Ca(2+) store because different Ca (2+) regulators, such as the inositol-1,4,5-triphosphate receptor, sarco/endoplasmic reticulum Ca(2+) -ATPase and secretory pathway Ca 2+ -ATPase, were demonstrated to localize on their membrane. The mechanisms involved in Ca(2+) release and uptake in the GA have now been established.
