Horizontol dissemination of TEM- and SHV-type beta-lactamase genes-carrying resistance plasmids amongst clinical isolates of Enterobacteriaceae
(SOC BRASILEIRA MICROBIOLOGIA, AV PROF LINEU PRESTES, 1374, 05508 SAO PAULO, BREZİLYA, 2008)
The extended-spectrum ?-lactamase (ESBL)-producing bacteria have been isolated at increasing frequency worldwide. Expression of ESBL is often associated with multidrug resistance and dissemination by resistance plasmids. ...
Synthesis, characterization and cyclization reactions of some new bisthiosemicarbazones
(Arkat, 2009)
The reaction of trans-1, 4-dichloro-2-butene 1 with selected phenols affords (E)-1, 4-bis(aryloxy)-2-butenes 2a-d which are converted into bis-thiosemicarbazones 3a-h via the reactions with thiosemicarbazide and 4-methyl ...

(Taylor & Francis LTD., 2009)
The chemical components and antimicrobial activity of the essential oils from Centaurea appendicigera C. Koch and Centaurea helenioides Boiss, two different endemic members of the genus Centaurea L. (Asteraceae), were ...
Improvement of superconducting properties of MgB2 by changing the argon ambient pressure and sintering conditions
(Institute of Physics Publishing, 2009)
We have investigated various characteristic properties depending on sintering conditions of MgB2 samples prepared by the standard solid state reaction method. It is inferred from experimental results that the crystallinity ...
