Alcohol intake of athletic university students
HRDLIČKOVÁ, Vanda
The topic of my bachelor's thesis is "alcohol intake of athletic university students." The rate at which alcohol is broken down depends on a number of physiological differences, such as gender or the proportion of muscle and fat tissue. Despite its certain protective effects, consumption cannot be recommended - especially in combination with sport. In the practical part, a quantitative method of data collection was used. The research group consisted of 128 university students aged 18-30. The aim was to compare the different alcohol consumption of athletic and non-athletic students. The results of both groups were very similar. The most frequently chosen option was "I consume alcohol only occasionally (about twice a month)", as it was chosen by 40% of sports and 33.3% of non-sports respondents. This was followed by consumption 3-5 times a month, which was chosen by 36% of athletes and 41% of non-athletes. There was a higher frequency of consumption (several times a week) in the case of 18% of athletes and 16.7% of non-athletes. The last 6% of sports and 9% of non-sports respondents consume alcohol every day. Another aim was to examine the degradation of alcohol from the system. I tested 20 students (10 athletes, 10 non-athletes) by using an alcohol tester. Athletic men eliminated a dose of 40 ml of 34% distillate within 30 minutes. Non-athletes in double time, i. e. 60 minutes. All women eliminated the same dose of alcohol within a similar period of time (60-105 minutes), regardless of the level of their physical activity. All participants also provided a weekly dietary record, including alcohol consummation. After entering dietary records into the Nutriservis program, I came to an average energy intake and the representation of individual nutrients, which can also affect the degradation itself.

Iron metabolism in Naegleria gruberi
Arbon, Dominik ; Šuťák, Róbert (advisor) ; Krijt, Matyáš (referee)
The metabolism of iron ions is a crucial process in all living organisms and its correct regulation is essential for basic life functions. Homeostasis of iron ions is closely regulated, it usually appears as a component of various proteins and plays role in many oxidation-reduction reactions. Naegleria gruberi is a non-pathogenic, free living protozoon, that serves as a laboratory model for closely related pathogenic Naegleria fowleri. This work focuses on the study of selected metabolites of N. gruberi, that were possible to detect and quantify by the means of modern metabolomic methods, and the influence on culture cultivated in environment with lack of iron ions was shown. The discovery of effect of this condition on the energetic metabolism of this protozoan is an important aspect of understanding the biological processes on cellular level. This method proved a significant influence on certain metabolites and modification of certain metabolic pathways as a direct effect of decreased availability of iron ions. Second part of this work was focused on the enzyme alcohol dehydrogenase, that was found in the genome of this protozoon. Unusual aspects of this enzyme include a N-terminal mitochondrial presequence, prompting about mitochondrial localization, and utilization of iron ion as a prosthetic...
