Hydrogen Ion Concentrations within the Alimentary Tract of Insects
نویسنده
چکیده
Larvae of Psychoda and of Chironomus (diptera) maintained in solutions of appropriate indicators show that the typical acidities (pH) prevailing within the several regions of the digestive tract are: esophagus 7.1; cardiac chamber 6.2; mesenteron 7.5; the latter being functionally an intestine. The acidity of the hindgut, pH 6.4, is due to the discharge of the malphigian tubules.

Objective(s): Gallic acid (GA) is a highly effective antioxidant, which its beneficial effects are well known, but its impact on expression of microRNAs (miRs) following hepatic ischemia-reperfusion (I/R) is not well recognized. Therefore, the current research was designed to specify the beneficial effect of GA on miRs (122 and 34a), liver functional tests, and histopathological alterations bey...
متن کاملHydrogen Ion Concentrations within the Ali- Mentary Tract of Insects
There has been a good deal of discussion as to the digestive and absorptive functions respectively pertaining to the several divisions of the intestinal tract of insects. The actual acidifies prevailing in the various regions of the gut are of special moment. Among other points of interest, questions arise as to the conditions of enzyme activity within the gut, and as to the possible r61e of su...

FMRFamide-related peptides (FaRPs) are a diverse and physiologically important class of neuropepeptides in the metazoa. In insects, FaRPs function as brain-gut neuropeptides and have been immunolocalized throughout the nervous system and alimentary tract where they have been shown to affect feeding behavior. The occurrence of FMRFamide-like immunoreactivity (FLI) was examined in the central ner...
