Oxygen Deficiency and Radiation Damage in the Insect Rhodnius

Oxygen Reperfusion Damage in an Insect

The deleterious effects of anoxia followed by reperfusion with oxygen in higher animals including mammals are well known. A convenient and genetically well characterized small-animal model that exhibits reproducible, quantifiable oxygen reperfusion damage is currently lacking. Here we describe the dynamics of whole-organism metabolic recovery from anoxia in an insect, Drosophila melanogaster, a...

The Cuticular Pattern in an Insect, Rhodnius Prolixus Stal

Radiation track and DNA damage

A gradient of positional information in an insect, Rhodnius.

Locke discovered a segmental gradient in Rhodnius which controls the polarity of the epidermal cell and gives positional information. The polarity is expressed by the orientation of folds in the adult epicuticle, which are aligned parallel to the contours in the gradient. It was later suggested that this gradient could be of a concentration of a diffusible substance. Because concentration gradi...

the relationship between learners critical thinking ability and their performance in the reading sections of the tofel and ielts test

the study reflected in this thesis aims at finding out relationships between critical thinking (ct), and the reading sections of tofel and ielts tests. the study tries to find any relationships between the ct ability of students and their performance on reading tests of tofel and academic ielts. however, no research has ever been conducted to investigate the relationship between ct and the read...
