A follow-up of antibiotics (tetracyclines, fluoroquinolones, cephalosporins, penicillins and amphenicols) in the bovine urine is important for two reasons: to understand if they are still present in organism, and whether their occurrence in urine might be considered as an environmental risk. A validated HPLC-MS/MS method (Decision 2002/657/EC) for(More)
Interconversion of hormonally active cortisol (F) into the corresponding inactive 11-keto form, cortisone (E), is catalyzed by 11beta-hydroxysteroid dehydrogenases (11β-HSDs). With a view to estimating in vivo activities of some 11β-HSD isoforms, the measurement of urinary F and E and their tetrahydro metabolites (tetrahydrocortisol, THF,(More)
We studied the effect of total body X-irradiation and partial hepatectomy on the acute phase protein gene expression in rat liver. Male rats of AO strain were irradiated with high X-ray doses, without any visible tissue damage. In contrast, partial hepatectomy consisted of surgical removal of 40% liver tissue. The changes in liver mRNA concentrations for(More)
A series of 278 organophosphate compounds acting as acetylcholinesterase inhibitors has been studied. The Monte Carlo method was used as a tool for building up one-variable quantitative structure-activity relationship (QSAR) models for acetylcholinesterase inhibition activity based on the principle that the target endpoint is treated as a random event. As(More)
BACKGROUND The influence of low doses of aflatoxin B1(AFB1) and partial hepatectomy (PH) on glutathione-S-transferase (GST) activity was studied in the plasma and liver of the rat. METHODS The animals were divided into four groups. The first (I) and the second (II) group were treated with AFB1 freshly dissolved in dimethyl sulphoxide (DMSO), and(More)
The Monte Carlo method was used for QSAR modeling of maleimide derivatives as glycogen synthase kinase-3β inhibitors. The first QSAR model was developed for a series of 74 3-anilino-4-arylmaleimide derivatives. The second QSAR model was developed for a series of 177 maleimide derivatives. QSAR models were calculated with the representation of the molecular(More)
OBJECTIVE To assess the erosive potential of various soft drinks by measuring initial pH and titratable acidity (TA) and to evaluate enamel surface roughness using different exposure times. MATERIALS AND METHODS The initial pH of the soft drinks (group 1: Coca-Cola; group 2: orange juice; group 3: Cedevita; group 4: Guarana, and group 5: strawberry(More)
BACKGROUND/AIM This study was undertaken to determine the changes and relationships between some important milk constituents as well as physical, rheological, and biochemical parameters of milk obtained from Serbian breastfeeding mothers. MATERIALS AND METHODS Physicochemical and biochemical parameters and the concentrations of vitamins, uric acid, and(More)
Milk contains plenty of enzymatic and non-enzymatic antioxidant components that probably account for the vital antioxidant protection of the infants at early stages of life against the development of complications induced by oxygen free radicals. Indigenous milk enzymes play a key role in regulating lactogenesis, including active involution of mammary(More)
