Gender-related variations in hemolymph parameters of Carabus lefebvrei (Coleoptera: Carabidae): HPLC analysis and phenoloxidase activity

We characterized the enzymatic activity of basal and total phenoloxidase and HLPC and SDS- PAGE profiles in hemolymph of Carabus lefebvrei males and females at different reproductive status. The phenoloxidase activity was activated by trypsin and inhibited by phenoloxidase activity specific inhibitor phenylthiourea. Our results demonstrated that both in males and females, there were no significant differences in the basal phenoloxidase activity between reproductive and virgin beetles, while the total phenoloxidase activity increased significantly in virgin specimens. Thus, resources seem to be invested to increase the humoral response in pre-reproductive phase forming a barrier against path…

DETERMINATION OF MAXIMAL FAT OXIDATION FOR PRESCRIBING EXERCISE IN SEDENTARY NON-OBESE TYPE 2 DIABETES SUBJECTS

Aim: To determine the exercise intensity that elicits the highest fat oxidation rate in sedentary non-obese subjects with type 2 diabetes. Methods: Eleven sedentary subjects with type 2 diabetes (T2DS) and eleven healthy sedentary subjects (HS), aged 45 to 65 and non-obese, were evaluated to a graded exercise test. Oxygen uptake (VO2) and fat oxidation rate (FAT) were detected. FAT was then plotted as a function of exercise intensity, expressed as percentage of VO2max. We determined the exercise intensity (%VO2max) at which fat oxidation was maximal (FATmax). Results: Absolute FATmax was not significantly different between T2DS and HS (0.51  0.13 vs. 0.56  0.29 g∙min-1). FATmax occurred a…

Are immune responses gender-related in Carabus lefebvrei (Coleoptera: Carabidae)?

The “live hard, die young” theory predicts the evolution of gender differences in immunocompetence, with males having a weaker immune system than females. To test this hypothesis in Carabus lefebvrei, total and basal phenoloxidase (PO) activities and lysozyme-like enzyme activity were compared among males and females of different reproductive status. The sexual dimorphism occurred only in reproductively active adults and for total and basal PO levels, while no significant differences were recorded between sexes in virgin adults. Differences were not recorded for lytic activity between sexes. Basal PO and lytic activities decreased in both males and females after mating, while the total PO v…
