“Staphylococcus aureus continues to be a major health problem. This species’ requirement for proline and proline transport from the extracellular environment is not well understood. Here, we identify a S. aureus low-affinity proline transport gene (opuD) with homology to the OpuD protein of Bacillus subtilis. Mutation of the

opuD gene caused a significant decline in proline uptake under low-affinity conditions as compared with wild type, but the opuD mutant strain showed no significant attenuation in a murine abscess model of infection. The S. aureus opuD gene was transcriptionally activated during growth in moderate osmolarity media with high levels of proline or glycine betaine independent of SigB. In murine abscesses, CA3 in vivo the opuD gene was activated at a later time point, Tozasertib manufacturer whereas the opuD expression dropped over the course of an 18-h period within murine urinary tracts. Transcriptional regulation

of opuD in S. aureus appears to be coordinated within this species when grown in moderate to high NaCl environments, but the level of extracellular proline had a marked effect on expression of this proline transport gene. The differential regulation of proline transport genes in S. aureus may be an adaptation for life in a variety of environments, including survival within the human body.”
“Thermal conductivity values of several laser materials were determined by photothermal measurements and compared AZD8055 to predicted values. The effect of the ytterbium doping concentration could be modeled using a simple

cationic mass difference model. For ytterbium content corresponding to an absorption coefficient of 10 cm(-1) (or 85% absorption of the pump power) Yb: GdVO4 (c-axis) and Yb: Gd3Ga5O12 laser materials present the highest measured thermal conductivity values of 8.1 W m(-1) K-1 and 7.7 W m(-1) K-1, respectively. Yb: Y3Al5O12, Yb: Lu3Al5O12, Yb: CaGdAlO4, and Yb: YAlO3 belong to the 6-7 W m(-1) K-1 range while Yb: CaF2 and Yb: Lu2SiO5 are situated in the 5-6 W m(-1) K-1 range. Other matrices such as Yb: SrLaGa3O7, Yb: CaGdAl3O7, Yb: SrGdGa3O7, and Yb: BaLaGa3O7 have thermal conductivity values lower than 5 W m(-1) K-1. With the knowledge of the thermal conductivities and the determination of the thermal expansion coefficients, thermal shock parameters are evaluated for several ytterbium doped laser hosts.
