BETA-GLUCANS: WHAT APPLICATIONS? A GENERAL OVERVIEW
Vannucci, Luca ; Mishra, Rajbardhan ; Lukáč, Pavol ; Tenti, Paolo ; Rajsiglová, Lenka ; Větvička, Václav ; 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.

SILVER NANOPARTICLES AND THEIR BACTERICIDAL EFFECT
Piksová, K. ; Weiserová, Marie ; Jedličková, A. ; Fojtík, A.
Rapid development of bio-nanotechnology lead to the new way in the combating of bacteria and to searching specific properties of nanomaterials The study of bactericidal nanomaterials is particularly timely considering the recent increase of new resistant strains of bacteria to the most potent antibiotics The present work studies the bactericidal effect of silver nanoparticles in the range of 10-30 nm on Gram-negative bacteria and Gram-positive bacteria

Musil, Stanislav ; Arslan, Y. ; Kratzer, Jan ; Vobecký, Miloslav ; Benada, Oldřich ; Matoušek, Tomáš ; Rychlovský, P. ; Ataman, O. Y. ; Dědina, Jiří
The main objective was to assess the generation efficiency in the optimized method of chemical vapor generation of gold by means of 198,199Au radioindicator. We also intended to characterize the volatile Au species formed by tetrahydroborate reduction.
