A chromosome-encoded beta-lactamase gene from Shewanella algae clinical isolate KB-1 was cloned and expressed in Escherichia coli. It encoded the Ambler class D enzyme OXA-55, sharing less than 55% identity with any other oxacillinases. Although conferring a narrow-spectrum beta-lactam resistance phenotype, OXA-55 had carbapenem-hydrolyzing activity that mirrored the reduced susceptibility to i...

The purpose of this study was to investigate the possibility of a placebo effect from carbohydrate (CHO) intake during prolonged exercise. Ten endurance-trained male cyclists performed 3 experimental trials consisting of 120 min of steady-state cycling at 61% VO2max followed by a time trial (TT) lasting approximately 60 min. During exercise participants ingested either plain water (WAT), artifi...

Knowledge of the prevalence of ESBL enzymes among P. aeruginosa strains compared to the Enterobacteraiceae family is limited. The phenotypic tests recommended by EUCAST for the detection of ESBL-producing Enterobacteriaceae are not always suited for P. aeruginosa strains. This is mainly due to the presence of other families of ESBLs in P. aeruginosa isolates more often than in Enterobacteriacea...

Perivascular adipose tissue (PVAT) is the fat tissue surrounding most of the vasculature and it has long been considered solely as vessel-supporting connective tissue. There are 2 major types of adipose tissue widely distributed throughout the body: white (WAT) and brown (BAT). PVAT is similar to BAT in rodents, but it was believed that only WAT existed in adult humans and BAT was present only ...

Abstract Tahitian bridal veil [ Gibasis pellucida (M. Martens & Galeotti) D.R. Hunt], a Central and South America native plant that is often confused with another more well-known invasive plant, small leaf spiderwort ( Tradescantia fluminensis Vell.), has become in natural areas throughout Florida. However, very little known regarding herbicide control or other methods. To begin the process...

T3 regulates energy metabolism, glucose and lipid metabolism and several markers of adipocyte differentiation in white adipose tissue (WAT). T3 levels in tissues are regulated by the deiodinases (D1, D2, D3 or DIO1, DIO2, DIO3, respectively). Aim: To analyze DIO1, DIO2 and DIO3 deiodinases activity and mRNA expression and T4 and T3 concentrations in omental (OM) and subcutaneous (SC) WAT from o...

OBJECTIVE To summarize studies testing the efficacy and safety of single-dose acetaminophen and ibuprofen for treating children's pain or fever. DATA SOURCES Reports were gathered by searching computerized databases (from their inception through May 2002) and registries, relevant journals, and bibliographies of key articles. STUDY SELECTION Seventeen blinded, randomized controlled trials wi...

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...
