Subglottic Eosinophilic Angiocentric Fibrosis (EAF) is an extremely rare disease of an elusive aetiology. It is chronically progressive benign condition that causes narrowing of the subglottic region leading to dysphonia and airway compromise. The diagnosis is historical and imaging is nonspecific. We report a case xc of 56-year-old lady referred to our institution with globus sensation, hoarse...

objective: in the present work, the effects of different fractions of coriandrum sativum (c. sativum), on pentylenetetrazole (ptz)-induced seizures and brain tissues oxidative damage were investigated in rats. materials and methods: the rats were divided into the following groups: (1) vehicle, (2) ptz (90 mg/kg), (3) water fraction (wf) of c. sativum (25 and 100 mg/kg), (4) n-butanol fraction (...

Received Jun 13, 2017 Revised Sep 21, 2017 Accepted Oct 4, 2017 Fast and accurate detection of the harmonic and interharmonic contribution of electric arc furnace (EAF) is crucial in identifying and to mitigate the undesired effects to the system. In this paper, periodogram, a fast and accurate technique is introduced for the analysis of the contribution. Based on a rule-based classifier and th...

Qualitative and quantitative high performance liquid chromatography with diode array detection (HPLC-DAD) was performed to characterize the presence of phenolic compounds in Andean purple corn. Phenolic compounds were analyzed by separating them in two main fractions: a water fraction (WF) and an ethyl acetate fraction (EAF). The WF rich in anthocyanins revealed the presence of cyanidin-3-gluco...

Despite a long tradition of use in the treatment of mental disorders, Viscum album L. (Ujjral; family – Viscaceae) has not been systematically investigated to validate its traditional claims. The methanol extract of V. album aerial parts, its ethyl acetate fraction (EAF) and 1-butanol fraction (BF) were screened for various neuropharmacological activities. The methanol extract, EAF and BF exhib...

Promoter-proximal pausing by initiated RNA polymerase II (Pol II) and regulated release of paused polymerase into productive elongation has emerged as a major mechanism of transcription activation. Reactivation of paused Pol II correlates with recruitment of super-elongation complexes (SECs) containing ELL/EAF family members, P-TEFb, and other proteins, but the mechanism of their recruitment is...

The complete nucleotide sequence and organization of the enteropathogenic Escherichia coli (EPEC) adherence factor (EAF) plasmid of EPEC strain B171 (O111:NM) were determined. The EAF plasmid encodes two known virulence-related operons, the bfp operon, which is composed of genes necessary for biosynthesis of bundle-forming pili, and the bfpTVW (perABC) operon, composed of regulatory genes requi...

Pseudomonas aeruginosa is an important pathogen in opportunistic infections in humans. The increased incidence of antimicrobial-resistant P. aeruginosa isolates has highlighted the need for novel and more potent therapies against this microorganism. Annona glabra is known for presenting different compounds with diverse biological activities, such as anti-tumor and immunomodulatory activities. A...

Eosinophilic angiocentric fibrosis (EAF) is a rare submucosal fibrosis without a well-developed differential diagnosis. Three cases of sinonasal tract EAF were identified in 2 women and 1 man, aged 49, 64, and 28 years, respectively. The patients experienced a nasal cavity mass, maxillary pain, or nasal obstructive symptoms of long duration. The process involved the nasal septum (n = 2), nasal ...

An ABB SVC Light® rated at 13.2 kV, 0-64 Mvar (capacitive) has been installed at the Gerdau plant in Charlotte, N.C., USA operating an electric arc furnace (EAF) with continuous charging for scrap-based steel production. The EAF, rated at 30/33 MVA, as well as a ladle furnace (LF) rated at 18 MVA are taking their power from a 100 kV supply grid. The fast control of SVC Light will improve the po...
