In the literature, only three Brevundimonas diminuta environmental isolates carrying metallo-β-lactamase genes were recently published. However, so far, no B. diminuta clinical isolates carrying these carbapenem resistance genes have been described. Here we report the first VIM-2 metallo-β-lactamase-producing B. diminuta clinical isolate obtained from an immunocompromised patient.

The present study was undertaken to investigate the effects of ß-alanine (a glycine agonist), on learning and memory in mice. ß-alanine (5, 10, 20 and 40 mg/kg i.p.) was administered for 6 successive days, to young (3 months old) and aged-mice (16 months old). The learning and memory parameters were assessed, using elevated plus-maze and passive-avoidance apparatus. The effect of ß-alanine (20 ...

PARTICIPANTS RATED THE PERCEIVED complexity and melodiousness of fractal (1/f ) tone sequences with specific ß values. Plotting the mean complexity and melodicity ratings against each other and against ß indicated that: (1) a melody’s spectral power density slope ( ß) can be used as an objective measure of its perceived complexity; (2) ß ≈ 1.50 for optimally preferred melodies; (3) perceived co...

BACKGROUND Metallo-β-lactamase-production among Gram-negative bacteria, including Pseudomonas aeruginosa, has become a challenge for treatment of infections due to these resistant bacteria. OBJECTIVES The aim of the current study was to evaluate the metallo-β-lactamase-production and carriage of bla-VIM genes among carbapenem-resistant P. aeruginosa isolated from burn wound infections. PATI...

Given the broad use of nanostructured crystalline titania films, an environmentally friendly and more sustainable synthesis route is highly desirable. Here, a water-based, low-temperature presented to synthesize foam-like films. A pearl necklace-like nanostructure introduced as tailored morphology via biotemplating with major bovine whey protein ß-lactoglobulin (ß-lg). It shown that crystalliza...

Saffron essential oil has a pleasant aroma and medicinal activities. However, it is sensible into the environmental condition. Therefore, it should be protected against unwanted changes during storage or processing. Encapsulation is introduced as a process by which liable materials are protected from unwanted changes. In the present study, different ratios (0:100, 25:75, 50:50, 75:25, and 100:0...

A series of amphiphilic tyrosine based self-healable, multi-stimuli responsive metallo-hydrogels have been discovered. Formation of these hydrogels is highly selective to Ni(2+) ions. The self-healing property and the stiffness of these metallo-hydrogels can be tuned by varying the chain length of the corresponding gelator amphiphile.

Exponential windowing is a widely used technique for suppressing the effects of old data as new data is added to a matrix. Specifically, given an n x p matrix Xn and a "forgetting factor" ß € (0, 1 ), one works with the matrix diag(/i'1_1, ß"~2, ... , \)Xn ■ In this paper we examine an updating algorithm for computing the QR factorization of diag(/j"-1, ß"~2 , ... , \)X„ and show that it is unc...
