For $U$ a balanced open subset of a Fréchet space $E$ and $F$ a dual-Banach space we introduce the topology $\tau _\gamma $ on the space ${\mathcal H}(U,F)$ of holomorphic functions from $U$ into $F$. This topology allows us to construct a predual for $({\mathcal H}(U,F),\tau _\delta )$ which in turn allows us to investigate the topological structure of spaces of vector-valued holomorphic functions. In particular, we are able to give necessary and sufficient conditions for the equivalence and compatibility of various topologies on spaces of vector-valued holomorphic functions.
n previous studies, one of the systolic time intervals - preejection period (PEP) - was used as an index of sympathetic activity reflecting the cardiac contractility. However, PEP could be also influenced by several other cardiovascular variables including preload, afterload and diastolic blood pressure (DBP). The aim of this study was to assess the behavior of the PEP together with other potentially confounding cardiovascular system characteristics in healthy humans during mental and orthostatic stress (head-up tilt test - HUT). Forty-nine healthy volunteers (28 females, 21 males, mean age 18.6 years (SD=1.8 years)) participated in the study. We recorded finger arterial blood pressure by volume-clamp method (Finome ter Pro, FMS, Netherlands), PEP, thoracic fluid content (TFC) - a measure of preload, and cardiac output (CO) by impedance cardiography (CardioScreen ®2000, Medis, Germany). Systemic vascular resistance (SVR) - a measure of afterload - was calculated as a ratio of mean arterial pressure and CO. We observed that during HUT, an expected decrease in TFC was accompanied by an increase of PEP, an increase of SVR and no significant change in DBP. During mental stress, we observed a decrease of PEP and an increase of TFC, SVR and DBP. Correlating a change in assessed measures (delta values) between mental stress and previous supinerest, we found that ΔPEP correlated negatively with ΔCO and positively with ΔSVR. In orthostasis, no significant correlation between ΔPEP and ΔDBP, ΔTFC, ΔCO, ΔMBP or ΔSVR was found. We conclude that despite an expected increase of sympathetic activity during both challenges, PEP behaved differently indicating an effect of other confounding factors. To interpret PEP values properly, we recommend simultaneously to measure other variables influencing this cardiovascular measure., J. Krohova, B. Czippelova, Z. Turianikova, Z. Lazarova, I.

Cíl studie: Cílem práce je přehledným způsobem zpracovat a komentovat nejnovější poznatky v oblasti preeklampsie, se zaměřením na příčiny onemocnění a jeho diagnostiku. Typ studie: Přehledný článek. Název a sídlo pracoviště: Ústav lékařské biochemie 1. LF UK, Praha; Ústav klinické biochemie a laboratorní diagnostiky, 1. LF UK, Praha. Závěr: Preeklampsie je stále podceňovanou komplikací v těhotenství, je diagnostikována až při klinické manifestaci. Nové hypotézy o vzniku této poruchy umožňují lepší pochopení patologických změn i identifikaci nových markerů způsobilých k časné diagnostice., Objective: To document and discuss current knowledge base in pre-eclampsia diagnostics and mechanisms of origin. Design: Review article. Settings: Institute of Medical Biochemistry 1st Faculty of Medicine, Charles University in Prague, Institute of Clinical Chemistry and Laboratory Medicine of the First Faculty of Medicine and General Teaching Hospital, Prague. Conclusion: Pre-eclampsia frequently diagnosed only after clinical symptoms manifestation remains underestimated complication of pregnancy. New theories about its origin enable better insight to the pathological process as well as identified new markers for early detection of the disorder., Libuše Arnoštová, Lenka Fialová, Ivan Matouš Malbohan, Tomáš Zima, D.
