Biological evolution versus evolutional systems: Comparison of rat and robot acquisition in comparable dynamic spatial tasks
Telenský, Petr ; Jiroutek, P. ; Svoboda, Jan ; Blahna, Karel ; Bureš, Jan
Ability to adapt to a continuously changing environment is inherent both to natural and artificial "inteligent systems". Our paper presents comparison of spatial learning in the living being (rat) and artifitial object (autonomous mobile robot controled by evolutionary system) using a similarily defined task. Individual chapters are given on rat and robot learning
Vizualizace velkých biologických tkáňových vzorků s použitím laserové konfokální mikroskopie
Čapek, Martin ; Kubínová, Lucie ; Hána, K. ; Smrčka, P.
In biology there is often necessary to visualize a biological specimen which size is greater when compared with the field of view of a used optical acquisition instrument. The visualization of such the specimen can be achieved by volume reconstruction. We study biological specimens by using a confocal laser scanning microscope which is able to capture a digital volume representation of the specimen. We investigate great specimens containing, for example, a human tooth pulp, an epithelial layer and a vascular bed of chick embryonic gut or chick embryonic kidneys
Multivalentní glykokonjugáty ve studiu interakce lektinových receptorů NK/NKT buněk
Vannucci, Luca ; Pospíšil, Miloslav ; Rossmann, Pavel ; Chernyavskiy, Oleksandr ; Kubínová, Lucie ; Křen, Vladimír ; Luptovcová, Martina ; Svoboda, Jan ; Kuldová, Markéta ; Bezouška, Karel ; Fišerová, Anna
The events following the administration of GN8 in vitro, in vivo and ex vivo, lead to increased expression of CD69. The CD69-dependent IFNg production is modulated by co-activation of NKG2D and Ly49 receptors. Glycodendrimers can assist the dissection of activation network of NK/NKT cell lectin-like receptors in rat and murine models
Multivalentní glykomika v imunoterapii experimentálních nádorů
Vannucci, Luca ; Pospíšil, Miloslav ; Krist, Pavel ; Křen, Vladimír ; Huliková, Katarína ; Luptovcová, Martina ; Svoboda, Jan ; Kuldová, Markéta ; Bezouška, Karel ; Rossmann, Pavel ; Difato, Francesco ; Mosca, F. ; Fišerová, Anna
Lectin-like receptors can modulate the cytotoxic, regulatory and dendritic cell responses by their interactions. GN8 multivalent glycoconjugates are able to internalize inside and activate NKR-P1 positive cells inducing production of IFN-gamma and expression of CD69. The final effect is a modulation of anticancer immunity with reduction of cancer growth
Vliv N-acetylcysteinu na velikost infarktu a expresi proteinkinázy C v myokardu potkana adaptovaného na chronickou hypoxii
Balková, P. ; Nováková, O. ; Ježková, J. ; Neckář, Jan ; Břeh, J. ; Staňková, B. ; Novák, F. ; Ošťádal, Bohuslav ; Kolář, František
Oxidative stress associated with chronic hypoxia plays an important role in the development of increased cardiac ischemic tolerance. ROS can play a dual role in the myocardial ischemic tolerance. They contribute to heart injury but also are involved in the protection
Úloha antioxidačních enzymů a proteinkinázy C v kardioprotektivním působení chronické hypoxie: Vliv diety o různém lipidovém složení
Hlaváčková, M. ; Balková, P. ; Nováková, O. ; Neckář, Jan ; Kolář, František ; Novák, F.
Cardioprotective effect of chronic hypoxia on the extent of myocardial ischemia/reperfusion injury can be modified by the diet lipid composition in a PKC-dependent manner
"Rearmament" in the Scientific Information Centre of the Institute of Physiology AS CR
Lisková, Zuzana
The review describes changes in the methods of work in the Scientific Information Centre of the Institute of Physiology caused by using electronic sources, propagation and experience with project solution
Vlastnosti vrstev na elektroerodovaném povrchu implantátů
Peřina, Vratislav ; Havránek, Vladimír ; Starý, V. ; Bačáková, Lucie ; Zemek, Josef ; Jirka, Ivan ; Jehlička, J. ; Vorlíček, Vladimír ; Fencl, J.
Plasma sprayed and in oil electroeroded implant surfaces were studied by various surface analytical techniques including cell adhesion.
Analýza endoplazmatického retikula konfokální mikroskopií
Janáček, Jiří ; Radochová, Barbora ; Demjénová, E. ; Schwarzerová, K. ; Tomori, Z. ; Karen, Petr ; Kubínová, Lucie
Image analysis techniques for preprocessing, segmentation and estimation of geometrical characteristics of fiber-like structures from images captured by a confocal microscope are presented. Methods are demonstrated on the study of endoplasmic reticulum of tobacco cells
Obnovení jasu a kontrastu datových souborů získaných konfokálním mikroskopem
Čapek, Martin ; Kubínová, Lucie ; Hána, K. ; Smrčka, P.
Images captured by a confocal microscope are degraded by light attenuation with depth. We developed a histogram warping based method to eliminate this problem
