A comparative study of the in vitro activities of XRP 2868, a new oral streptogramin, against 266 anaerobic gram-positive clinical isolates using the agar dilution method showed that the XRP 2868 MICs for 95% (254 of 266) of isolates were < or =0.5 microg/ml. XRP 2868 MICs for only two strains, one being Clostridium clostridioforme (MIC, 16 microg/ml) and the other being Clostridium difficile (...

We report the first experimental results on a high-gain harmonic-generation (HGHG) free-electron laser (FEL) operating in the ultraviolet. An 800 nm seed from a Ti-Sapphire laser has been used to produce saturated amplified output at the 266 nm third-harmonic. The results confirm the advantages of the HGHG FEL: stable central wavelength, narrow bandwidth and small pulse energy fluctuation. The ...

The study extends research on the impact of commodity futures investments on portfolio performance by incorporating levered futures directly into the optimization problem. Differences in portfolio performance between fully collateralized and levered futures arise primarily in the presence of investment constraints. The attractiveness of portfolios is also affected by differences in commodity in...

Canine anaplasmosis is a zoonotic disease caused by Anaplasma phagocytophilum and platys transmitted ticks. In Sri Lanka, only few studies are available as this often neglected (underdiagnosed) in clinical practice due to the non-specific signs. This communication describes seroprevalence, laboratory findings of 266 dogs seropositive for spp. identified from 450 anaemic presented Gampaha, Colom...
