One hundred fifty AAC(6')-Ib-positive gram-negative isolates collected between 1981 and 1991 were examined by PCR for the presence of the aac(6')-Ib-cr variant and other plasmid-mediated quinolone resistance (PMQR) genes. None had the aac(6')-Ib-cr variant, qnrA, qnrS, qnrC, or qepA, but two strains collected in 1988 had qnrB alleles, making these the earliest known PMQR genes.

In recent years, mobile operations have gained wide popularity among mainstream users, and banks tend to follow this trend. But are bank customers ready to move forward? Mobile banking appears to be a natural extension of Internet banking, . Thus, to predict consumer decisions to adopt mobile banking, it’s useful to understand the pattern of adoption of Internet banking (IB). This investigation...

BACKGROUND Retroviruses rely on host factors for cell entry, replication, transcription, and other major steps during their life cycle. Human Immunodeficiency Virus-1 (HIV-1) is well known for utilizing a plethora of strategies to evade the host immune response, including the establishment of latent infection within a subpopulation of susceptible cells. HIV-1 also manipulates cellular factors i...

Naive T cells have the capacity to expand in a lymphopenic environment in a process called homeostatic expansion, where they gain a memory-like phenotype. Homeostatic expansion is dependent on competition for a number of factors, including growth factors and interactions with their selecting self-MHC molecules. In contrast to conventional T cells, it is unclear whether class Ib-restricted CD8+ ...

CONTEXT Pseudohypoparathyroidism type Ib (PHP-Ib) is a rare disorder resulting from genetic and epigenetic aberrations in the GNAS complex. PHP-Ib, usually defined by renal resistance to parathyroid hormone, is due to a maternal loss of GNAS exon A/B methylation and leads to decreased expression of the stimulatory G protein α (Gsα) in specific tissues. OBJECTIVE To clarify the usefulness of m...

The purpose of this experiment was to investigate the behaviour of fastand slow growing chickens, when the birds had access to the outdoors. Fifty of both 1-day-old male chicks of a laying hybrid ISA BROWN (IB) and broilers ROSS 308 (RS) were kept in two pens in the same building. In each group ten birds were marked with a colored spray. From three weeks of age the birds had access to the outdo...

Type Ib and Ic supernovae (SNe Ib/Ic) originate from hydrogen-deficient massive star progenitors, of which the exact properties are still much debated. Using SN data in literature, we investigate optical $B-V$ color SNe Ib/Ic at $V-$band peak show that systematically bluer than Ic. We construct models helium-rich helium-poor progenitors various masses using radiation hydrodynamics code STELLA d...
