Three morphologically different types of lesion were observed: (i) myelin sheath vacuolation with an apparently intact axon generally flattened against one side of the sheath, (ii) myelin sheath vacuolation with a degenerating axon or whorls of myelin-like figures and (iii) an empty vacuolated myelin sheath with no detectable axon.
A promising alternative to conventional grafting is the use of artificial nerve grafts, of which the Integra Neurosciences Type I collagen sheath (NeuraGen™, Integra Neuroscience; Plainsboro, NJ, USA) is commercially available for treating short nerve defects clinically.
An ion-rich sheath, i.e., a positively charged boundary, and an electron-rich sheath, i.e., a negatively charged boundary, were studied using computer simulations and laboratory experiments.
In addition, Lpar1 regulates the breakdown of the myelin sheath (i.e., demyelination) that occurs after nerve injury (Inoue Lpar1 regulates the breakdown of the myelin sheath (i.e., demyelination) that occurs after nerve injury (Inoue et al. 2004).
I thought the sheath of body hair and long drop of my voice would be the most shocking transformations, but the greatest change is that I can now admit how much I need other people.
("I always used sheaths when prudence dictated it," Wells claims).
The g-ratio was calculated for at least 120 randomly selected apparently intact myelin sheaths (i.e., non-vacuolated) per genotype, with the GRatio for ImageJ plugin (Ingo Bormuth, http://gratio.efil.de/).de/
Very recently, and for the first time, ultrastructure analysis of the surface of H. pylori 26695 has revealed a sheathed, surface organelle, coded by the cag-PAI genes, HP0527 (forms sheath around the pilus needle) and HP0532/ cagT (forms the base of the pilus) [ 58].
As for a sheath, however, I'd spot mine in a second.
My friend offered me a dress that I had admired, a sheath of pure lines, in black chiffon and organza, by Galanos.
