A ciprofloxacin-resistant, nalidixic acid-susceptible mutant of Staphylococcus aureus (F145) contained no mutations within gyrA, gyrB, grlA, and grlB or within norA or its promoter region. MICs and accumulation studies suggest the role of a novel multidrug efflux pump.

Parosteal bone tumors involving the small bones of the hand and the foot are rare. Their clinical and imaging features may imitate other bone tumors, leading to incorrect diagnosis and management. Histological examination of the lesion will establish the correct diagnosis. Bizarre parosteal osteochondromatous proliferation was first described in 1983 by Nora et al.1 In a report of 35 Mayo Clini...

Nora is a joint project between Concordia University, Canada, and University Karlsruhe, Germany, through which a group of researchers of Auction and Negotiation meet together in order to deeply investigate the differences and possible impacts of the use of different electronic market mechanisms. The objective of the project is to build a comprehensive research framework and knowledge base from ...

During the 1980s, it was commonly accepted that congenital heart defects (CHDs) were secondary to multifactorial components. Nora and Nora presented a graph of a Gaussian curve with a vertical bar. Individuals of a general population were under the curve with individuals on the left side of the Gaussian curve carrying the least amount of CHD genetic predisposing factors and individuals on the r...

A Doll’s House brought about the disillusionment of many men and women in the 19th century with its unique probing of the dynamics of married life as well as its uncompromising critique of a society that did not respect the freedom of human beings. Drawing on the works of stylisticians like Jeffries and Mills as well as using stylistic tools including endearments and sexist ...

A sparfloxacin-susceptible clinical isolate of Staphylococcus aureus was grown in increased concentrations of sparfoxacin. The presence of mutations in gyrA, gyrB, grlA and grlB genes was analyzed. The primary point mutation was located in the gyrA gene (Glu-88 to Lys). Two further mutation steps appeared in the amino acid change Ser-80 to Tyr in GrlA. No mutations occurred in the gyrB or grlB ...
