The present studies demonstrate that the ability of supplemental selenite to alter the in vitro growth of canine mammary tumor cell line 13 was dependent on the quantity and duration of selenium exposure and on the culture density. Exposure to 3.2 microM selenite did not significantly alter growth but led to an increase in intracellular glutathione (GSH). The severity of growth inhibition betwe...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
BACKGROUND Inflammatory and structural changes of the airway mucosa are chronic features of asthma. The mechanisms underlying these changes and their modulation by steroid prophylaxis have not been clarified. OBJECTIVE We postulated that asymptomatic ongoing allergen exposure could drive airway inflammation as well as changes in the extracellular matrix (ECM), and that inhaled steroids could ...
