results two bacterial types, st208, and st218, were identified in all 140 samples. the st208 mainly came from icu and department of respiratory medicine, while st218 from department of plastic surgery; 70.21% of st208 and 84.78% of st218 were carbapenem-resistant acinetobacter baumannii (crab) and carbapenem-susceptible acinetobacter baumannii (csab), respectively. multidrug-resistance genes in...

background: this study aimed to evaluate the role of efflux pump regulator and oxa-23 genes in imipenem resistance acinetobacter baumannii strains isolated from hospitalized patients in tehran, iran. methods: this study was conducted on 60 a. baumannii isolates collected from patients admitted to the shahid motahari and taleghani hospitals in tehran during 2013-14. antibiotic susceptibility tes...

INTRODUCTION: Pseudomonas aeruginosa is one of the most common nosocomial pathogens. The emergence of extended spectrum β-lactamases (ESBLs) has been increasingly reported as a major clinical concern worldwide. The main aim of the present study was to determine the distribution of bla OXA, bla PER-1, bla VEB-1, and bla GES-1 genes among ESBL-producing P. aeruginosa isolated from two distinct p...

A large variety of behaviors that are essential for animal survival depend on the perception and processing of surrounding smells present in the natural environment. In particular, food-search behavior, which is conditioned by hunger, is directly driven by the perception of odors associated with food, and feeding status modulates olfactory sensitivity. The orexinergic hypothalamic peptide orexi...

Thorpe, A. J., J. A. Teske, and C. M. Kotz. Orexin A-induced feeding is augmented by caloric challenge. Am J Physiol Regul Integr Comp Physiol 289: R367–R372, 2005; doi:10.1152/ajpregu.00737.2004.— Orexin neurons are stimulated by conditions that are glucoprivic, suggesting that orexin signaling may be increased during nutritional duress. We have previously shown that injection of orexin A (OxA...

Acinetobacter bereziniae (formerly Acinetobacter genomospecies 10) isolate Nec was recovered from a skin sample of a patient hospitalized in Paris, France. It was resistant to penicillins, penicillin-inhibitor combinations, and carbapenems. Cloning and expression in Escherichia coli identified the carbapenem-hydrolyzing class D β-lactamase OXA-229, which is weakly related to other oxacillinases...

Global dissemination of imipenem-resistant (IR) clones of Acinetobacter baumannii - A. calcoaceticus complex (ABC) have been frequently reported but the molecular epidemiological features of IR-ABC in military treatment facilities (MTFs) have not been described. We characterized 46 IR-ABC strains from a dataset of 298 ABC isolates collected from US service members hospitalized in different US M...

Furan-2,5-diylbis(phenylmethanol) is a key intermediate to access sub(oxa)porphyrins. Previously, this was accessible from fossil-derived furan using highly dangerous lithium reagents. Presently, we have produced cashew apple bagasse (CAB), via the formation of 5-hydroxymethylfurfural (HMF). CAB non-food biomass containing cellulose and hemicellulose. From CAB, obtained HMF in yield 310 mg/g CA...

OBJECTIVES Acinetobacter baumannii is a significant pathogen in health care settings. In recent years, an increase in carbapenem resistance among A. baumannii due to Ambler class B metallo-beta-lactamases or class D OXA carbapenamases has been reported. In this study we detected the presence of OXA carbapenamases and coproduction of metallo-beta-lactamases (blaVIM and blaIMP ) by phenotypic and...
