(Scibulcom Ltd, Sofia, 2001)
The article describes a study of the protective effect of dandelion (Taraxacum officinale L. Asteraceae) in combination with two xenobiotics: ciprofloxacin and pyralene. For that purpose, methanolic extracts of the plant ...
Analysis of sister-chromatid exchanges and micronuclei in cultured human lymphocytes treated with insulin
(Charles Univ Prague, First Faculty Medicine, Prague 6, 2001)
Insulin is an anabolic hormone that may facilitate development of malignant diseases in various susceptible tissues due to stimulation of mitotic divisions. In this work, an evaluation of mitogenic and genotoxic effects ...
Antioxidant status of patients with acute myocardial infarction
(Dustri-Verlag Dr Karl Feistle, Deisenhofen-Muenchen, 2003)
Objectives: It has been suggested that dietary selenium (Se) deficiency is implicated in the etiology of cardiovascular disease. In this study, we examined the antioxidant status of patients with acute myocardial infarction ...
The effect of the antioxidant catalase on oestrogens, triiodothyronine, and noradrenaline in the Comet assay.
(Teratogenesis, carcinogenesis, and mutagenesis, 2003)
Metabolic changes in the phenolic groups of steroidal oestrogens accompanied by the generation of quinones and reactive oxygen species underlie their mutagenic effects. Although nonsteroidal hormones and related compounds ...
Xylazine, an alpha(2)-adrenergic agonist, induces apoptosis of rat thymocytes and a thymocyte hybridoma line in vitro
(Prous Science, Sau-Thomson Reuters, Barcelona, 2003)
In our previous experiments, we demonstrated that xylazine, an alpha(2)-adrenergic agonist, stimulated proliferation of thymocytes triggered by concanavalin A. In contrast, higher concentrations of xylazine were inhibitory. ...

Quantitative H-1 NMR measurements revealed Delta(11(13)) sesquiterpene gamma-lactones as the main constituents (greater than or equal to 1% per weight of dried plant material) in the crude extracts of the aerial parts of ...
Reactive oxygen species (ROS), but not nitric oxide (NO), contribute to strain differences in the susceptibility to experimental arthritis in rats
(Elsevier Gmbh, Munich, 2007)
There is extensive evidence for the critical role of reactive oxygen species (ROS) and nitric oxide (NO) produced by phagocytes in development of inflammatory processes and pathogenesis of numerous diseases, including ...
Low-oxygen and high-carbon-dioxide atmosphere improves the conservation of hematopoietic progenitors in hypothermia
(Wiley, Hoboken, 2009)
BACKGROUND: During short-term storage of hematopoietic cells (HCs) at 4 degrees C a substantial decline in number and in functional capacity of progenitors occurs after 3 days. We hypothesized that physiologic O-2 and CO2 ...
Variability in germination and in temperature and storage resistance among Paenibacillus larvae genotypes
(Elsevier Science Bv, Amsterdam, 2008)
There are several methods for cultivation of Paenibacillus larvae, the causative agent of American foulbrood (AFB) in honey bees. Protocols for detection of sub-clinical levels of the bacterium from honey and bee samples ...
