Suplementace kreatinu u sportovce s hyperhomocysteinemií
Kohlíková, E. ; Petr, M. ; Navrátil, Tomáš ; Přistoupilová, K. ; Přistoupil, T. I. ; Pelclová, D. ; Žák, J. ; Heyrovský, Michael
One month's administration of creatine (CR) in the dose of 5 g/day to 11 young active sportsmen affected their daily amount of CR and creatinine excreted into urine. The probands were divided into 4 groups, according to the amount of CR found in urine, and of folates and of vitamin B12 determined in blood. The ganges of folates and vitamin B12 were mutually reciprocal. Each group utilized CR as donor of one- and two-carbon (1C and 2C) units by means of homocysteine (HoCySH), folates, and vitamin B12, in different metabolic pathways. In 10 men the CR administration was accompanied by an increase of HoCySH level in blood, while for the last man, with accidentally discovered hyperhomocysteinemia, after the month's CR administration the HoCySH level dropped by 50 %.
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.
Vliv suprafyziologických dávek kreatinu na homocysteinový metabolismus u sportovců
Kohlíková, E. ; Petr, M. ; Přistoupilová, K. ; Šenholdová, Z. ; Přistoupil, T. I. ; Pelclová, D. ; Žák, J. ; Heyrovský, Michael ; Navrátil, Tomáš
One month´s administration of creatine (CR) in the dose of 5 g/day to 11 young men affected their daily amount of CR, creatinine, and thiodiglycolic acid (TDGA) excreted into urine. The probands were divided into 4 groups, according to the amount of CR found in urine, and of folates and of vitamin B12 determined in blood. The changes of folates and vitamin B12 were mutually reciprocal, as well as muscle mass and body fat. Each group utilized CR as donor of one- and two-carbon (1C and 2C) units by means of homocysteine (HoCySH), folates, and vitamin B12, in different metabolic pathways.
Interaction of Creatine Metabolism with Three Possible Enzymatic Pathways Using Homocysteine
Přistoupilová, K. ; Navrátil, Tomáš ; Petr, M. ; Šenholdová, Z. ; Přistoupil, T. I. ; Pelclová, D. ; Žák, J. ; Kohlíková, E. ; Heyrovský, Michael
Alternative administration of creatine (CR) and vitamin B12 in food supplements has confirmed our finding that CR is a source of 2C units. They can be utilized in oxidative pathway, an intermediate of which is thiodiglycolic acid (TDGA). 2C units can be used also in other metabolic pathways, in which folates and vitamin B12 coenzymes take part together with homocysteine.
Participation of electrochemistry in the studies of human metabolism
Navrátil, Tomáš ; Šenholdová, Z. ; Přistoupilová, K. ; Přistoupil, T. I. ; Heyrovský, Michael ; Pelclová, D. ; Žák, J.
The contribution deals with explanation of metabolism of long term supplemented creatine in human organism. This process differs from metabolism of natural endogenous creatine, which is excreted in form of creatinine. Exogenous creatine induces increase of peptide formation, of body mass, and of intracellular fluid.
The use of composite graphite electrode for voltammetric determination of phenylglyoxylic acid
Šenholdová, Z. ; Navrátil, Tomáš ; Shanmugam, K. ; Barek, J. ; Žák, J.
A composite electrode prepared from graphite powder and epoxy resin was applied as a working electrode for the determination of phenylglyoxylic acid (one of the metabolites of styrene) in human urine. Cathodic differential pulse stripping voltammetry was used and optimum conditions have been found giving the limit of determination about 5 mg L-1. All results were compared with those obtained using hanging mercury drop electrode. For the confirmation of suggested mechanism of the electrochemical reaction the elimination voltammetry with linear scan was used.
The Use of Voltammetry by Interesting Poisons by Lead
Šenholdová, Z. ; Navrátil, Tomáš ; Vlček, K. ; Žák, J. ; Mádlová, P. ; Surovcová, H.
Two interesting nonprofessional intoxications by lead and their treatments are described. The first one was the case of a man, who by mistake swallowed 20 peaces of lead slugs. The other one was the case of the woman, who used a lead containing liniment prescribed by an astrologist to treat diabetes.
IT outsourcing v praxi - případová studie
Myslivec, Oldřich ; Kubešová, Vlasta (advisor) ; Žák, Jaromír (referee)
Cílem této práce je analýza využívání IT outsourcingu v konkrétní firmě a následná optimalizace některých popisovaných procesů. Na základě teoretických poznatků a za pomocí detailního rozboru stávající situace v oblasti činností a služeb, byla navržena možná optimalizace některých řešení a procesů, jež mohou vést k efektivnější spolupráci mezi klientem a poskytovatelem služeb. Práce je rozdělena na dvě části: teoretickou a praktickou. V teoretické části je vysvětlen pojem IT outsourcingu. Jsou definovány jeho základní rysy včetně pozitiv a rizik vyplývajících z jeho zavedení, systematické dělení druhů outsourcingu a také jeho historické souvislosti s možným vývojem do budoucna. Praktická část se zabývá podrobnou analýzou vykonávaných aktivit a činností v rámci IT outsourcingu klienta. Práci uzavírá vlastní optimalizace možných oblastí jako je identifikace slabých a silných míst v poskytovaných službách, časového plánu, druhů úkolů, dokumentace, komunikace s vedením firmy.
