This study focused on nuclear and nucleolar area changes in Malpighian tubule cells of Rhodnius prolixus, an hematophagous insect, vector of Chagas' disease. Male and female adult insects were dissected after a 28-day ...

Starvation is a physiologic stress and can significantly alter the structure of hepatic cells. This work aims to detect morphological changes in mice hepatocyte under starvation physiologic stress, based on silver staining ...

In the present study changes in nuclear area and chromatin distribution in the Malpighian tubules of a blood-feeding insect, the vector of Chagas' disease were analysed. Male and female adult insects were dissected, after ...

We have analysed the response of the acidophilic chemolithotroph Thiobacillus ferrooxidans to phosphate starvation. Cultivation of the bacteria in the absence of added phosphate induced a remarkable filamentation of the ...

It was hypothesized that (1) previous experience of aphids on a host plant leads to differences in their feeding behavior relative to aphids without previous experience on it and that (2) a change in the physiological state ...

Microsomal lauric acid 12-hydroxy lauric acid (ω)-hydroxylation and fatty acid peroxisomal β-oxidation were studied in kidney tissue from starved rats. Starvation increased the microsomal ω-hydroxylation and peroxisomal ...

In this work the microsomal lauric acid ω-hydroxylation, fatty acid peroxisomal β-oxidation, and the levels of cytochrome P-450 IVAI were studied in liver tissue from starved rats. Starvation increased the peroxisomal ...
