Cold hardiness of larvae of the fruit fly, \kur{Drosophila melanogaster} (Diptera: Drosophilidae)
KORBELOVÁ, Jaroslava
We assessed survival of larvae of the fruit fly, Drosophila melanogaster at low temperatures (0°C and 5°C) after rearing them under seven different acclimation regimes. Larvae that have developed in a standard diet at 25°C showed 50% mortality after 12,6 min of the exposure to 0°C (Lt50 = 0.21 h). In contrast, larvae that have developed in a diet enriched with glycerol at 15°C, and were cold acclimated at 5°C during last two days of their development, had Lt50 = 38.6 h. It means that it was possible to increase the Lt50 at 0°C more than 180-fold using simple manipulations with rearing temperatures and diet composition. The physiological differences in duration of larval development, fresh mass, dry mass, hydration and total contents of proteins, lipids and glycogen between the larvae belonging to different acclimation variants are described. The samples for future detailed metabolomic analysis were prepared.

Význam lipidů v metabolismu tuků
Kohlíková, E. ; Petr, M. ; Přistoupilová, K. ; Přistoupil, T. I. ; Pelclová, D. ; Žák, J. ; Heyrovský, Michael ; Navrátil, Tomáš
In course of last two years we compared values of 34 parameters, obtained from 11 young active sportsmen given 5 g of creatine (CR) daily during 1 month. Among these parameters were the products of metabolic pathways, the changes of which are connected with the development of atherosclerosis. This holds for the levels of cholesterol (CH), triacylglycerols (TAG) and homocysteine (HoCySH), and for the levels of vitamin B12 and of folates in blood.
