Ground red hot pepper agar in the isolation and presumptive identification of Cryptococcus neoformans
(Wiley, Hoboken, 2002)
The study compared ground red hot pepper agar (GRHP) and Guzzotia abyssinica creatinine agar (GACA), a medium routinely used for isolation of Cryptococcus neoformans. In order to confirm the capacity of GRHP to support the ...
Genotoxicity potential of 8-Cl-cyclic adenosine monophosphate assessed with cytogenetic tests in vivo
(Elsevier Science Inc, New York, 2004)
Background. Growth-modulating noncytotoxic activity of 8-chloro-adenosine 3,5-cyclic monophosphate (8-Cl-cAMP) showed inhibitory effect on growth of a wide variety of cancer cell lines in vitro and in vivo. To assess ...
Aminoglycoside resistance in members of the Staphylococcus sciuri group
(Mary Ann Liebert, Inc, New Rochelle, 2007)
This study investigated the prevalence of aminoglycoside resistance and genes encoding aminoglycoside-modifying enzymes in members of the Staphylacoccus sciuri group. A total of 304 S. sciuri group member isolates (284 S. ...
Comparison of spontaneous antibiotic resistance frequency of Salmonella typhimurium growth in glucose amended continuous culture at slow and fast dilution rates
(Taylor and Francis Inc., 2005)
The objective of the study was to determine the frequency of spontaneous acquisition of resistance to select antibiotics by Salmonella Typhimurium (ST) when grown in glucose amended continuous flow culture at slow (D = ...
Combined effects of plant extracts and xenobiotics on liposomal lipid peroxidation. Part 4. Dandelion extract - Ciprofloxacin/pyralene
(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 ...
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. ...

(Springer, New York, 2009)
Mutagenic activity of estradiol evaluated by an in vitro micronucleus assay - Short communication
(Akademiai Kiado, Budapest, 2005)
The objective of the present study was to evaluate possible genetic changes in cultured human lymphocytes treated with estradiol, using the cytokinesis block micronucleus assay. Eight experimental concentrations of estradiol ...
