New foms of distribution of television news coverage
Lukáč, Pavol ; Čermák, Miloš (advisor) ; Javůrek, Adam (referee)
This thesis "New Forms of Distribution of News Coverage" sets out its target to briefly and concisely describe technologies that have affected our lifes in recent years and are going to affect them even more in next few years. The theoretical part of this work consists of the brief analysis of perception of new media (new forms of distribution) through the eyes of Czech media theoretics at the beginning of the 21st. Century, then there is a reflection on the thesis of Marshall McLuhan that "We live in the retribal period and the world is just a global village". In addition, the content of this theoretical part of thesis also consists of the description and comparison of new forms of distribution of TV signal, namely IPTV and Internet video, two ways of distribution which the author finds most progressive and interesting. The last, but not least important part of this part of this work is the comparison between the new forms of TV coverage distribution in Hong Kong and Central Europe. The practical part consists of the analysis of the survey based on participation of 70 Facebook users who answered questions on whether they watch tv news or which form of signal distribution are they subscribed to at home. The results of this survey are particulary interesting as the sample was aged between 18-25...

Purification of water soluble bioactive polysaccharides from biomass of heterotrophic mutant alga Chlorella vulgaris G11.
Sushytskyi, L. ; Lukáč, Pavol ; Bleha, R. ; Čopíková, J. ; Vannucci, Luca ; Sinica, A. ; Kaštánek, P.
Water extract obtained from biomass of mutant alga Chlorella vulgaris G11 was deproteinized and then purified with AEC on DEAE Sepharose FF and SEC on Sepaphadex G-75 superfine columns. Two high MW (>1000 kDa and 98,3 kDa) polysaccharides (CPS1 and CPS3) were eluted with water and 0.5M NaCl on DEAE column, and heteropolysaccharide with MW of 15 kDa (CPS2) was also eluted with water on DEAE. The former fractions were identified as branched rhamnans, the latter one as branched xylogalactofuranan of unusual structure. CPS1 shown properties of unstable polimer: according to GPC analysis and by using light scattering and RI detectors it was found, that some fraction of polymers (260-800 kDa) have self-assembling properties in aqueous solution, and MW of this fraction decreased during some time while polimer with initially bigger MW (>1000 kDa) became bigger. CPS3 was eluted with 0.3-0.5 M of NaCl on DEAE Sepharose FF column and have MW of 98,3 kDa. Cell toxicity of the products were tested in vitro on cell cultures for different concentrations

Beta-Glucans: What Applications? A General Overview
Vannucci, Luca ; Mishra, Rajbardhan ; Lukáč, Pavol ; Tenti, Paolo ; Rajsiglová, Lenka ; Větvička, V. ; Šíma, Petr
Glucans are polysaccharides derived from various sources (e.g. mushrooms, algae, yeast, barley). They can target immune receptors, like Dectin-1 expressed on dendritic cells - antigen presenting cells. Otherwise, interest is rising for their use not only for modulation of immunity, but also of cholesterol levels, or as possible vaccine adjuvants, nanocarriers and functional food components. We will shortly review some aspects in human and veterinarian applications.
