Study of sperm proteins in modelspecies of chondrostean and teleostean fish
Koubek, Pavel; Elzeinová, Fatima; Linhart, O.; Pěknicová, Jana
2003 - anglický
Specific in the study of fish reproduction is outer fertilization. spermatozoa are usually expelled into host medium of the outer encironment. The cells have to cope with an extremely different encironment and their protection against the outer environment is much weaker than that of oocytes. The way of fertilization also differs from mammalian fertilization.

Dynamic and role of cytosekeletal proteins in mammalian sperm cells
Paleček, J.; Dvořáková, K.; Pěknicová, Jana; Kubátová, Alena; Moore, H. D. M.
2003 - anglický
The cytoskeleton of sperm head consists of resistant structural proteins of the nucleus and of perinuclear theca, which are largely rosponsible for the shaping of the nucleus. three mahjor cyteskeletal proteins, actin, tzubnulin and spectrin, are present in the head of mammalian spermatohzoa. Maoreober, the mictotubular cytoskeleton also contains other dynamic proteins, which have a morphological function within the cell and which are responsible for cell signalling processes.

Iscare IVF a.s. had a long record of successful azoospermic treatment since 1997, when the first pregnancies by MESA a TESE were published in the Czech republic. A series of diferent implanted laboratory techniques supported good results from last year. The medical problem is solved during the other field of application-histlogical findings and immunofluorescent methods.

Regulation and localization of sperm akaps during capacitation, activation, induced acrosomal reaction and binding to the oocyte
Kyselová, Vendula; Pěknicová, Jana
2003 - anglický
Recent evidence suggests that the cAMP-dependent protein kinase A (PKA) is localized to specific subcellulatr compatrments trought association with A Kinase Anchoring Proteins (AKAPs). The AKAPs now represent a functionally related family of regulatory proteins containing a conserved PKA binding domain and a unique targeting sequence that direct the PKA-AKAP complex to subcellular structures.

Cryocrystallography of biological Macromolecules
Řezáčová, Pavlína
2002 - anglický
Crystals of biological macromolecules at near to room temperature are sensitive to X-rays and frequently suffer from radiation damage, especially when X-ray experiments are carried out on highly intense synchrotron beamlines. Performing such experiments at cryogenic temperatures greatly reduce, or eliminate radiation damage and thus produce higher quality diffraction data.

Phytoremediation and biodegradation of PCB in soil
Ryšlavá, E.; Krejčík, Zdeněk; Macek, Tomáš; Macková, M.
2002 - anglický
This is a part of the research work focused on study of possible mutual relationships of microorganisms and plants in PCBs metabolism. Polluted soil was obtained from a site which has been contaminated by PCBs for a long time. This soil was used for isolation of bacteria whixh potentially participate in biolodegradation of PCBs. The same contaminated soil was used for experiments under real conditions. Within six months three plant species were cultivated-tobaco (Nicotiana tabacum), black nighshade (Solanum nigrum) and alfalfa (Medicago sativa) - and decrease of PCBs was measured.
