A comparison of differential protein expression in response to copper challenge between the two breeds of sheep, complemented by ultrastructural studies, has affirmed the exquisite sensitivity of NR sheep to Cu-induced oxidative stress and suggest that this may arise from within mitochondria.
Invertebrate skeletal muscle, ultrastructural studies have suggested that the Z-line and extracellular intermediate filaments are linked, although a structural basis for this has remained elusive.
Ultrastructural studies have shown that the pigmented (PE) and non-pigmented (NPE) cell layers of the ciliary epithelium are connected by gap junctions.
Ultrastructural studies have indicated that the thin layer of neuronal processes surrounding the dark rosettes correspond to the outer plexiform layer, and the central region of the pale rosettes correspond to the inner plexiform layer of the normal retina.
Ultrastructural studies have demonstrated that the development of the spore wall in G. rufa is similar to the genus Discina (in the Helvellaceae family) and to the other Sarcosomataceae, especially Plectania nannfeldtii; both of these species have fine secondary wall spore ornaments.
Ultrastructural studies have shown that the morphology of the Itacaiunas and Curionopolis viruses resembles that of animal-infecting members of the family Rhabdoviridae.
Ultrastructural studies have most likely failed to reveal the loukoumasome because it occurs only once per neuron, and because, having an electron density comparable to that of the surrounding cytoplasm, it fails to catch the eye.
However, no electroretinogram or ultrastructural studies have been performed in this breed.
For example, classical ultrastructural studies have demonstrated in experimental animals innervation of serotonergic neurons by noradrenergic locus coeruleus neurons [ 4].
Ultrastructural studies have shown that Type III cells form conventional synapses with the nervous system [ 29, 30, 20, 9].
