Therefore, the aim of the present study was to investigate whether the induction of prediabetes upon feeding rats with HFD for 15 weeks was able to cause ultrastructure
alterations of a large blood vessel, the aorta, using TEM and blood chemistry.
Light deficiency caused by severer shading was also revealed in those changes in the leaf physiological characteristics (Fig.2) and biochemical features (Fig.3) as well as reflected in the ultrastructures
of chloroplasts in leaves (Fig.4).
is homogeneous as observed by SEM.
lactiflora mesophyll cell ultrastructures
from S1 to S4, we found that the mesophyll cell ultrastructures
of shaded and sun-exposed plants in S1 were similar to each other (Fig.
The ultrastructural observation of the leaf cuticle of three plant species processed for TEM by different methods suggests that classification of cuticular ultrastructures
according to specific and oversimplified patterns must be interpreted with caution.
To understand the effects of DEN on the endocrine system and the mechanisms for the sex differences in the animal hepatocarcinogenesis initiated by DEN, we designed the present experiment to study the effects of DEN on the pituitary ultrastructure
, serum levels of several hormones, as well as expression and activities of several sex-differentiated liver enzymes.
The resemblance between the semi-nacre of cyclostome bryozoans and the nacre of molluscs has important implications for the comparative organizational control of skeletal ultrastructures
in the two groups.
of neuronal axons of mice in embedment-free section TEM (a) and conventional epoxy TEM (b).
The primary ultrastructures
of both problematica were obliterated by recrystallization, but the growth habit and chemical composition of the recrystallized structures provided an insight into the original mineralogy.
The biomineralization systems of Palaeozoic problematic tubeworms and calcareous polychaete tubeworms are comparable in respect of their ability to produce advanced skeletal ultrastructures
. The foliated structures (e.g.
caulleryi) and one sabellid species (Glomerula piloseta) were selected for the study of their skeletal ultrastructures
