Staphylococcus aureus is a common cause of intramammary infections, which frequently become chronic, associated with the ability of the bacteria to produce biofilm. Here, we report a relationship between the ability to produce chronic bovine mastitis and biofilm formation. We have classified bovine mastitis S. aureus isolates into three groups based on the presence of particular genetic element...
To evaluate the diagnostic validity of new assays for bone-specific alkaline phosphatase (BAP), we compared measurements of total alkaline phosphatase (TAP) in serum with results for three different assays of serum BAP in healthy adults (n = 119), patients with chronic nonskeletal disorders (n = 123), and patients with metabolic bone diseases (n = 113). Serum TAP was determined by a standard co...
Glycine N-methyltransferase (GNMT) affects genetic stability by (a) regulating the ratio of S-adenosylmethionine to S-adenosylhomocystine and (b) binding to folate. Based on the identification of GNMT as a 4 S polyaromatic hydrocarbon-binding protein, we used liver cancer cell lines that expressed GNMT either transiently or stably in cDNA transfections to analyze the role of GNMT in the benzo(a...
ŠIMKO P., SKLÁRŠOVÁ B., ŠIMON P., BELAJOVÁ E. (2006): Effect of plastic packages on benzo[a]pyrene concentration in sunflower oil. Czech J. Food Sci., 24: 143–148. Commercially available sunflower oil and the same oil distilled additionally in a molecular evaporator (to remove naturally occurring compounds) was spiked with benzo[a]pyrene (BaP) at the levels of 37.1 and 38.6 μg/kg, respectively....
BACKGROUND Polycyclic aromatic hydrocarbons are suspected developmental neurotoxicants, but human exposures typically occur in combination with other neurotoxic contaminants. OBJECTIVE AND METHODS We explored the effects of benzo[a]pyrene (BaP) on neurodifferentiation in PC12 cells, in combination with a glucocorticoid (dexamethasone, used in preterm labor), an organophosphate pesticide (chlo...
Mutant phoR cells show a clonal variation phenotype with respect to bacterial alkaline phosphatase (BAP) synthesis. BAP clonal variation is characterized by an alternation between a Bap+ and Bap- phenotype. The switching is regulated by the phoM operon and the presence of glucose; the pho-510 mutant form of the phoM operon abolishes both BAP clonal variation and the effect of glucose (B.L. Wann...
BACKGROUND/AIM Bone alkaline phosphatase (bAP) is known to be an important biochemical marker of bone formation. Through the present study, we intended to find out whether there is any advantage in bAP determination, as a routine biochemical marker, besides intact parathyroid hormone (iPTH) in hemodialysis patients. METHODS In a population of 140 hemodialysis patients, bAP and iPTH were deter...
Benzopyrene (BaP) is polycyclic aromatic hydrocarbon (PAH), and is chemically modified in the animal body to form a number of metabolites that may elicit a various toxicity. However, the effect of BaP on neuroblastoma differentiation has remained unclear. We have studied the effect of BaP on neurite outgrowth using human SH-SY5Y neuroblastoma cells induced to differentiate by all-trans-retinoic...
Apical meristems, first, second and third-fourth axillary buds of Ludwigia repens were cultured on Murashige and Skoog (MS) medium containing various concentrations of 6-benzylaminopurine (BAP), thidiazuron (TDZ) and αnaphthaleneacetic acid (NAA) for micropropagation. Micropropagation was best achieved from apical meristem on MS medium containing 0.05 mg dm TDZ and 0.1 mg dm NAA. It was noted t...
