Previous reports have documented an attenuated p53 response to DNA damage in hepatocytes isolated from enzyme-altered foci (EAF). Here, we have studied this p53 response in vivo in rats with EAF. These animals received repeated doses of diethylnitrosamine (DEN) for 6 weeks and a challenging dose 24 h before death. Liver sections were then analysed using an immunohistological procedure for p53, ...

Phenolic rich ethyl acetate fraction (EAF) from lotus leaves was prepared and its bioactive components, antioxidant and cytoprotective effects were investigated. EAF showed high total phenolic content and flavonoid content and contained rutin (11,331.3±4.5 mg/100 g EAF), catechin (10,853.8±5.8 mg/100 g EAF), sinapic acid (1,961.3±5.6 mg/100 g EAF), chlorogenic acid (631.9±2.3 mg/100 g EAF), syr...

The application of electric arc furnace ladle slag (EAF slag) in cement products might be limited due to the volume expansion and instability created by late hydration. Proper control technique should developed before reuse (LS). With addition aluminum powder alkali-activated pastes, porous materials were produced. By adjusting activator modulus between 1.25 2.00, fine pores produced foamed mat...

The 1-kb BamHI-SalI fragment from plasmid pMAR2 termed the enteropathogenic Escherichia coli (EPEC) adherence factor (EAF) probe was cloned in pUC19 and pK18. The nucleotide sequence of this fragment was determined, and a set of primers was designed to amplify a 397-bp region associated with pMAR2 by PCR. An analysis of the whole EAF sequence with database libraries indicated no significant hom...

The pneumatic lime injection during the electric arc furnace (EAF) process by insufflation lances mounted on walls has gained much interest in latest years. main advantages, comparison to traditional procedure of lumps addition within scrap bucket, can be summarized raw materials consumption reduction, foaming benefits, operational cost and improvement environmental aspects. In proposed work, a...
