Mechanisms of Exfoliation
THE NORMAL EXFOLIATION PROCESS Exfoliation occurs naturally as outworn stratum corneum cells detach and are removed from the skin’s surface. Replacement of stratum corneum cells occurs by a self-renewal process as epidermal cells move upward from the basal layer, the stratum basalis, and through the subsequent two layers, the stratum spinosum and stratum granulosum, to reach the stratum corneum...
متن کاملExfoliation of layers in NaxCoO2.
We proposed and developed an exfoliation process for layer-structured NaxCoO2 to prepare CoO nanosheets. Na+ ion exchange by acid treatment was utilized to expand the spacing between the two CoO2 layers in NaxCoO2. Ethylamine was then effectively utilized for the exfoliation of cobalt oxide sheets having nanometer-order thickness and high aspect ratio. CoO nanosheets were observed by TEM microg...
متن کاملAlveolar bone necrosis and spontaneous tooth exfoliation associated with trigeminal herpes zoster: a report of three cases
J Korean Assoc Oral Maxillofac Surg 2012;38:177-83) Herpes zoster is a viral infection caused by the reactivation of the varicella zoster virus, an infection most commonly affecting the thoracolumbar trunk.

Their main features are given in Table I (overleaf, pp. I22 and 123). All the patients were males between the ages of 6o and 76 years. The capsular exfoliation was associated with phakodonesis, iridodonesis, glaucoma, primary ...
متن کاملProteomic analysis of exfoliation deposits.
PURPOSE To increase knowledge of the biochemical composition of lenticular exfoliation material (XFM) by using proteomic approaches. METHODS Anterior lens capsules from patients with and without exfoliation syndrome (XFS) were homogenized in formic acid and subjected to cyanogen bromide (CNBr) cleavage, and the pattern of chemically generated fragments was compared by SDS-PAGE after silver st...
