Three new anilido-oxazolines, ortho-C(6)H(4)(NHAr')(4,4-dimethyl-2-oxazoline) [Ar'=2,4,6-trimethylphenyl, HNPh(TriMe)Oxa (1); 2,6-diisopropylphenyl, HNPh(DiiPr)Oxa (2); 2-methoxyphenyl, HNPh(OMe)Oxa (3)], have been prepared. Reactions of 1 or 2 with one molar equivalent of ZnEt(2) in tetrahydrofuran or hexane solution give the zinc ethyl complexes (NPh(TriMe)Oxa)ZnEt (4) and (NPh(DiiPr)Oxa)ZnEt...

We investigated the mechanisms involved in imipenem resistance in 23 clinical strains of Acinetobacter baumannii. Sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) analysis showed the presence of a 30-kDa protein in imipenem-intermediate A. baumannii (IIAB) and imipenem-resistant A. baumannii (IRAB) strains; this protein was almost undetectable in imipenem-susceptible A. baum...

BACKGROUND Emergence of multidrug-resistant Acinetobacter baumannii has resulted in the treatment failure of related infections and an increase in patient mortality. The presence of class D β-lactamases (oxacillinases) in this organism is an important mechanism underlying resistance to beta-lactam antibiotics. OBJECTIVES The aim of this work was to investigate the correlation between oxacilli...

conclusions the present study showed that bla oxa-23-like was the most frequent carbapenemase identified among carbapenem-resistant a. baumannii isolated in tehran hospitals. evaluation of antibiotic resistance genes in a. baumannii, is necessary to control further dissemination of these antibiotic resistant genes. results results showed that 123 of 131 (93.89%) acinetobacter species, possessed...

White adipose tissue (WAT) has been examined to determine whether the gene encoding metallothionein (MT), a low-molecular-weight stress response protein, is expressed in the tissue and whether MT may be a secretory product of adipocytes. The MT-1 gene was expressed in epididymal WAT, with MT-1 mRNA levels being similar in lean and obese (ob/ob) mice. MT-1 mRNA was found in each of the main adip...

conclusions the high prevalence of oxa β-lactamase and high genetic diversity of p. aeruginosa indicated that the resistance of p. aeruginosa might be expanding in our studied hospitals. background pseudomonas aeruginosa is main bacterial pathogen accountable for nosocomial infections. furthermore, it could potentially become resistant to β-lactams, aminoglycosides and fluoroquinolones antibiot...

A baseline study of soil-transmitted helminthiases was carried out in Nakhon Si Thammarat Province, southern Thailand. The study sites were Wat Krou Chou Primary School and nearby villages in Sichon district, and Wat Thang Phoon Primary School and nearby villages in Chalerm Phrakiat District. Surveys of the schoolchildren's stools were conducted by the Kato-Katz technique. The results showed th...

Abstract Optimum herbicide use is a key factor affecting the success of any integrated weed management strategy. The main objective current study was to implement method based on spectrometer measurements for in situ evaluation efficacy and detection potentially herbicide-resistant weeds. Field trials were conducted Greece between 2018 2020 several durum wheat fields ( Triticum Desf.). In all t...

The present study investigated potential sex-related differences in the metabolic response to carbohydrate (CHO) ingestion during exercise. Moderately endurance-trained men and women (n = 8 for each sex) performed 2 h of cycling at approximately 67% Vo(2 max) with water (WAT) or CHO ingestion (1.5 g of glucose/min). Substrate oxidation and kinetics were quantified during exercise using indirect...
