To compare the sensitivity of various protocols for methicillin-resistant Staphylococcus aureus (MRSA) surveillance, active surveillance for detecting MRSA nasal colonization was performed on 97 members of the medical staff and 218 patients in the Intensive Care Unit (ICU) of a university hospital. Duplicate nasal swabs were collected from each participant. One was plated directly on a blood ag...

In this study the effect of growth regulators in different concentrations were tested for shoot and root development micropropagation pomegranate with nodal explants. The explants collected morning, third node from tip. healthy plants which authenticated. For MS media was supplemented alpha-naphthalene acetic acid (NAA), indole-3-butyric-acid (IBA), 6-benzyl aminopurine (BAP) kinetin their comb...

The carcinogenic polycyclic aromatic hydrocarbons (PAHs) are active primarily at the site of entry to the body. Lung cancer following inhalation of PAH-containing aerosols such as tobacco smoke is one likely example. A suggested mechanism for this site preference is a slow passage of the highly lipophilic PAHs through the thicker epithelia of the conducting airways, accompanied by substantial l...

Polycyclic aromatic hydrocarbons (PAHs) are immunotoxicants in fish. In mammals, phase I metabolites are believed to be critically involved in the immunotoxicity of PAHs. This mechanism has been suggested for fish as well. The present study investigates the capacity of immune organs (head kidney, spleen) of rainbow trout, Oncorhynchus mykiss, to metabolize the prototypic PAH, benzo[a]pyrene (Ba...

Several compounds originating from cruciferous vegetables and citrus fruits bind to and activate the aryl hydrocarbon receptor (AhR). This receptor plays an important role in the toxicity of the known tumour promoter and potent AhR-agonist 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). However, vegetables and fruits are generally considered as healthy. Therefore, besides the AhR activation, the na...

7,8-Dihydrobenzo[a]pyrene (7,8-H2BaP) was metabolized by rat liver microsomes to form 7,8,9,10-tetrahydro-BaP trans-9,10-diol, 7,8,9,10-tetrahydro-BaP cis-9,10-diol, 7-hydroxy-7,8-H2BaP, 8-hydroxy-7,8-H2BaP, two phenolic products of 7,8-H2BaP [abbreviated as 7,8-H2BaP phenol 1 and phenol 2 according to their elution order on reversed-phase high-performance liquid chromatography (HPLC)], 4,5,7,8...

The activation of benzo(a)pyrene (BaP) to DNA-binding metabolites in early-passage embryo cell cultures prepared from various species of rodents was investigated by exposing cells from mice (BALB/c and Sencar), rats (Wistar and Fischer 344), and Syrian hamsters to [3H]BaP for various lengths of time. The BaP:DNA adducts containing cis-vicinal hydroxyl groups such as those formed from 7 beta,8 a...

BackgroundCoarctation of the aorta (CoA) is often treated percutaneously. The aim this study was to describe immediate results percutaneous management native aortic coarctation (NaCoA) and recoarctation (ReCoA) at our institution.MethodsWe identified all patients with NaCoA or ReCoA who underwent dilatation by either balloon angioplasty (BAP) endovascular stent implantation (ESI) between 2011 2...

The aim of the present study was to evaluate the influence on urinary excretion levels of N-telopeptide of type I collagen (NTX) and deoxypyridinoline (DPD) as a useful marker for bone resorption, and on serum-bone alkaline phosphate (BAP) levels as a useful marker for bone formation and an early marker of osteoblast differentiation in patients with rheumatoid arthritis (RA) treated with methot...
