The main objective of this study was to investigate whether a rat model of pre-diabetes can be beneficial in assessing alterations to large blood vessel ultrastructures
using TEM analysis.
Meanwhile, we have also looked into the chloroplast ultrastructures
affected by shading (Fig.
The homogeneous tube ultrastructure
could be an artefact of the preservation as organic cuticles of various modern invertebrates often have fibrous ultrastructures
lactiflora protective enzymes activities, made mesophyll cell ultrastructures
more intact, the chloroplasts more round and the grana lamellaes arrange relatively neatly, which led to enhance its photosynthesis rate (Pn) and transpiration rate (Tr).
Indeed, it has been reported that exogenous proline application negatively affects chloroplast and mitochondrial ultrastructures
(HARE et al., 2001).
At least six different types of ultrastructures
have been identified in plant cuticle transversal sections and the different layers have been generally described as either amorphous, lamellate, or reticulate [8, 10].
The pituitary ultrastructures
looked normal on day 35.
The combination of brachiopods and bryozoans within a single unified secretory model and the relative dearth (in comparison with molluscs) of studies of bryozoan ultrastructures
have contributed to the theory that lophophorates are incapable of producing the range and diversity of skeletal ultrastructures
found in molluscs (Carter, 1979; Carter and Clark, 1985).
Based on the findings from the in vitro experiment summarized above, a new interpretation on cell ultrastructures
in the embedment-free section TEM is proposed (Kondo, 2010): First, differences in the compactness of cytoplasmic lattices represent those in the protein concentration in the cytoplasmic matrix; second, when loose and compact lattices are contiguous without any membranous compartmentations in a given cell, a cytoplasmic matrix domain occupied by the compact lattice is at a gel state, while remaining domains of the same cell at a sol state (Fig.
The Ortonella-like porostromate problematica, found throughout the entire 1.9 m thick succession, and Hedstroemia, found mainly in the bioherm facies, were observed under SEM for documentation of ultrastructures
At least thirteen distinct tube ultrastructures
have hitherto been described (Vinn et al.
The aim of the paper is (1) to find structural support or the supposed unique biomineralization system of cirratulids, (2) to compare cirratulid skeletal structures with phylogenetically close sabellids and serpulids n order to find similarities, and (3) to find whether he skeletal ultrastructures
of cirratulids have evolved ince the Oligocene.
