4) Hepatocytes in the periportal region of the liver lobule
, in contrast, actively produce new glucose, which then is exported into the bloodstream primarily by a different glucose transporter molecule called Glut 2.
Studies conducted with various hepatotoxicant chemicals will examine the hypothesis that gene and protein profiles can distinguish toxicants acting at different areas of the functional liver lobule
The percentage of acini present per lobule
at a given age indicates cancer risk.
Among the areas of progressive deficit in the placebo group were regions concerned with functioning of the attentional system, including the posterior thalamus, tectum, posterior cingulate, and superior parietal lobule
Central vein: Blood exits each liver lobule
by way of the central vein, which feeds into the hepatic vein.
In addition, these authors demonstrated that mice in which the Ah receptor has been eliminated display decreased mammary gland size and suppressed lobule
development, suggesting a critical role of the Ah receptor in normal and TCDD-exposed mammary gland development.
During separation of the tumor lobule
in the sphenoid sinus, bright-red blood spurted from the lateral and inferior walls of the left sphenoid sinus.
Clear cell change usually constitutes an incidental finding, limited to a lobule
or only part of it, and rarely associates with calcifications (Figure 5, A and B).
There were significant positive correlations for activation at the right inferior parietal lobule
and the angular gyrus for happy faces, in the left fusiform gyrus and the right posterior insula for sad faces, and in the left parietal lobule
for angry faces.
2) In studying the extent of lobular neoplasia (ALH or LCIS) as focal ([less than or equal to] 1 lobule
affected per core biopsy) or diffuse (>1 lobule
affected per core biopsy), as well as correlating the mammographic findings, we found that only those biopsies (2 of 26) with diffuse lobular neoplasia were upgraded at excision to infiltrating carcinoma.
But the group with the Alzheimer's disease-associated apoE [epsilon]4 allele showed increased brain activation compared with those without that allele, most prominently in the frontal regions bilaterally and in the left paracentral lobule
Although the number of Purkinje cells was unchanged following the complex motor training, the increased volume of the paramedian lobule
of the cerebellar cortex and the increased number of parallel fiber synapses per Purkinje cell were sufficient anatomical changes to result in improved motor skills.
