Mast-Cell Degranulation Induced by Physical Stimuli Involves the Activation of Transient-Receptor-Potential Channel TRPV2 - Trang 113-124 - 2012
D. ZHANG, Andreas Spielmann, L. Wang, Guanghong Ding, Fang Huang, Qin Gu, Wolfgang Schwarz
A characteristic of mast cells is the degranulation in response to various stimuli. Here we have investigated the effects of various physical stimuli in the human mast-cell line HMC-1. We have shown that HMC-1 express the transient receptor potential channels TRPV1, TRPV2 and TRPV4. In the whole-cell patch-clamp configuration, increasing mechanical stress applied to the mast cell by hydros...... hiện toàn bộ
Adhesion, Growth and Differentiation of Osteoblasts on Surface-Modified Materials Developed for Bone Implants - Trang 403-417 - 2011
Marta Vandrovcová, Lucie Bačáková
This review briefly outlines the history and possibilities of bone reconstruction using various types of artificial materials, which allow interaction with cells only on the surface of the implant or enable ingrowth of cells inside the material. Information is also provided on the most important properties of bone cells taking part in bone tissue development, and on diseases and regenerati...... hiện toàn bộ
Spectral analysis of heart rate variability in sleep. - Trang 369-376 - 2005
Petr Bušek, J Vaňková, J Opavský, Johanna Salinger, Soňa Nevšímalová
Spectral analysis of heart rate variability (HRV) during overnight polygraphic recording was performed in 11 healthy subjects. The total spectrum power, power of the VLF, LF and HF spectral bands and the mean R-R were evaluated. Compared to Stage 2 and Stage 4 non-REM sleep, the total spectrum power was significantly higher in REM sleep and its value gradually increased in the course of ea...... hiện toàn bộ
Genetic defects of cytochrome c oxidase assembly - Trang S213-S223 - 2004
Petr Pecina, H Houst'ková, J Zeman, J Houštěk
Cytochrome c oxidase (COX), the terminal enzyme of the mitochondrial respiratory chain, is one of the key functional and regulatory sites of the mammalian energy metabolism. Owing to the importance of the enzyme, pathogenetic mutations affecting COX frequently result in severe, often fatal metabolic disorders. No satisfactory therapy is currently available so that the treatment remains lar...... hiện toàn bộ
The influence of wine polyphenols on reactive oxygen and nitrogen species production by rat macrophages RAW 264.7 - Trang 393-402 - 2008
M Číž, Martina Pavelková, Lucie Gallová, Jarmila Králová, Lukáš Kubala, Antonı́n Lojek
The aim was to study the antioxidant properties of four wine
polyphenols (flavonoids catechin, epicatechin, and quercetin, and
hydroxystilbene resveratrol). All three flavonoids exerted
significant and dose-dependent scavenging effects against
peroxyl radical and nitric oxide in chemical systems. The
scavenging effect of resveratrol was significantly lower. All
polyphenols decreased produc...... hiện toàn bộ
Age-Dependent Salt Hypertension in Dahl Rats: Fifty Years of Research - Trang S35-S87 - 2012
Josef Zicha, Z Dobešová, M. Vokurková, H Rauchová, Silvie Hojná, Michaela Kadlecová, Michal Behuliak, Ivana Vaněčková, Jaroslav Kuneš
Fifty years ago, Lewis K. Dahl has presented a new model of salt hypertension – salt-sensitive and salt-resistant Dahl rats. Twenty years later, John P. Rapp has published the first and so far the only comprehensive review on this rat model covering numerous aspects of pathophysiology and genetics of salt hypertension. When we summarized 25 years of our own research on Dahl/Rapp rats, we h...... hiện toàn bộ
Biogenesis of eukaryotic cytochrome c oxidase - Trang S27-S41 - 2006
Lukáš Stibůrek, Hana Hansíková, Markéta Tesařová, Leona Černá, J Zeman
Eukaryotic cytochrome c oxidase (CcO), the terminal component of the mitochondrial electron transport chain is a heterooligomeric complex that belongs to the superfamily of heme-copper containing terminal oxidases. The enzyme, composed of both mitochondrially and nuclear encoded subunits, is embedded in the inner mitochondrial membrane, where it catalyzes the transfer of electrons form red...... hiện toàn bộ
Cardiovascular parameters in rat model of chronic renal failure induced by subtotal nephrectomy - Trang S81-S88 - 2010
Jitka Švíglerová, Jitka Kuncová, Lukáš Nalos, Zbyněk Tonar, Daniel Rajdl, Milan Štengl
Chronic renal failure (CRF) is associated with high incidence of
cardiovascular complications. To clarify pathogenesis of CRF
numerous animal models have been developed. The aim of our
work was to describe methodology of subtotal surgical renal
ablation in rat and to characterize some biochemical and
cardiovascular parameters of this animal model. Male rats
underwent 5/6 surgical nephrecto...... hiện toàn bộ
Allosteric Modulation of Ligand Gated Ion Channels by Ivermectin - Trang S215-S224 - 2014
Hana Zemková, Vendula Tvrdoňová, Anirban Bhattacharya, Marie Jindřichová
Ivermectin acts as a positive allosteric regulator of several ligand-gated channels including the glutamate-gated chloride channel (GluCl), aminobutyric acid type-A receptor, glycine receptor, neuronal α7-nicotinic receptor and purinergic P2X4 receptor. In most of the ivermectin-sensitive channels, the effects of ivermectin include the potentiation of agonist-induced currents at low conc...... hiện toàn bộ
