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 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...

BACKGROUND Viola canescens Wall. ex. Roxb. exhibits analgesic, antimalarial and antispasmodic activities. It is used folklorically for the treatment of liver diseases, hypertension, malaria and cancer. The current study investigates phytochemical constituents, antioxidant and hepatoprotective activity of solvent extracts of whole plant of Viola canescens. METHODS Phytochemicals, acute toxicit...

Enzyme-altered foci (EAF) develop in rat liver in response to carcinogen treatment. Our hypothesis is that EAF adapt to genotoxic stimuli by lowering their expression of p53 and that such decreased p53 expression confers a growth advantage on the hepatocytes present in EAF. After a single neonatal dose of diethylnitrosamine (DEN), rats were treated with either 2 - 12 additional doses of DEN or ...

In the present study, the fractionated extracts of Sesbania grandiflora bark were prepared and evaluated for their biological activities. The ethyl acetate fractionate (EAF) showed high antioxidant activity along with free radical scavenging and reducing mechanisms. The free radical scavenging antioxidant activity of EAF was 69.3 ± 3.6% where its Trolox equivalent antioxidant capacity was 13.6 ...

The enteropathogenic Escherichia coli adherence factor (EAF) probe detects isolates of enteropathogenic E. coli that exhibit localized adherence to HEp-2 cells. A 21-base oligonucleotide probe was constructed on the basis of a sequence from within the 1-kb EAF probe and was shown to have greater sensitivity and specificity than the EAF fragment probe in detecting localized adherent E. coli.

Introduction. Management of open abdomen (OA) with enteroatmospheric fistula (EAF) in morbid obese patient with comorbid disease is challenging. We would like to report the management of septic OA in morbid obese patient with EAF which developed after strangulated recurrent giant incisional hernia repair. We would also like to emphasize, in this case, the conversion of EAF to ileostomy by the h...

OBJECTIVE To identify novel genes implicated in epilepsy with auditory features (EAF) in phenotypically heterogeneous families with unknown molecular basis. METHODS We identified 15 probands with EAF in whom an LGI1 mutation had been excluded. We performed electroclinical phenotyping on all probands and available affected relatives. We used whole-exome sequencing (WES) in 20 individuals with ...

Power quality is becoming a more concern of today’s power system engineer due to rapid growth of non-linear loads in distribution network. Electrical Arc Furnace (EAF) is one of the responsible causes for deteriorating power quality in the distribution network. Hence electric arc furnace model is needed to study and to analyze the power quality in the distribution network. This paper presents a...
