ISOLATION AND CHARACTERIZATION OF MANNAN-BINDING PROTEINS FROM BOAR SEMINAL PLASMA
Jelínková, Petra; Liberda, J.; Ryšlavá, H.; Tichá, M.; Jonáková, Věra
2003 - anglický
The mannan-binding proteins of boar seminal plasma may be involved in the formation of the sperm oviductal reservoir in pig. The ability of these proteins to interact both with the complex of D-mannose-containing saccharide structures and heparin may also play an important role in the sperm release from the oviductal reservoir and in the capacitation process.

Characterization of peptide proteinase inhibitors isolated from boar seminal plasma
Jelínková, Petra; Tichá, M.; Jonáková, Věra
2003 - anglický
Seminal plasma of different mammalian species contains various types of proteins. Proteinase inhibitors are important components of seminal plasma and were found in all tested species. In the present communication we have shown that serine proteinase inhibitors participate (under physiological conditions) in the formation of associated complexes with other proteins from boar seminal plasma.

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.

Properties of serine proteinase inhibitors from boar seminal plasma
Jelínková, Petra; Maňásková, Pavla; Tichá, M.; Jonáková, Věra
2002 - anglický
Inhibitors of proteinases are important components of seminal plasma. Their biological function in seminal plasma is to protect protein components of seminal plasma and male and female reproductive tracts against proteolytic degradation. My work is concentrated on characterization of inihibitors found in seminal plasma.
