Comamonas testosteroni strain R2 was isolated from a continuous culture enriched by a low concentration of phenol-oxygenating activities with low Ks values (below 1 μM). The draft genome sequence of C. testosteroni strain R2 reported here may contribute to determining the phenol degradation gene cluster.

Background CMR R2* is the gold standard for monitoring cardiac iron overload in patients with hemoglobinopathies. The R2* value is obtained by fitting the signal at different echo times (TEs) to an appropriate decay model. Patients with heavy cardiac iron burden (R2*>100 Hz) exhibit rapid signal, leading to a plateau in the later images. Two approaches have been used to address this. The first ...

This investigation sought to determine if cycling power could be accurately modeled. A mathematical model of cycling power was derived, and values for each model parameter were determined. A bicycle-mounted power measurement system was validated by comparison with a laboratory ergometer. Power was measured during road cycling, and the measured values were compared with the values predicted by t...

Accurate R2* measurements are critical for many abdominal imaging applications. Conventionally, R2* maps are derived via the monoexponential fitting of signal decay within a series of gradient-echo (GRE) images reconstructed from multichannel datasets combined using a root sum-of-squares (RSS) approach. However, the noise bias at low-SNR TEs from RSS-reconstructed data often causes the underest...

Soil phosphorus (P) release capability could be assessed through the degree of P saturation (DPS). Our main objective was to determine DPS and, hence, P threshold DPS values of an Ultisol treated with triple superphosphate (TSP), Gafsa phosphate rocks (GPR), or Christmas Island phosphate rocks (CIPR), plus or minus manure. P release was determined by the iron oxide-impregnated paper strip (stri...

Microalbuminuria is thought to reflect the severity of inflammation-induced systemic vascular permeability. The present study investigated the effect of early administration of metformin or insulin on microalbuminuria in traumatized critically ill patients. Between April 2006 and October 2007, thirty-one non-diabetics traumatized patients with systemic inflammatory response syndrome (SIRS) and ...

Eiszler, C.F. (2002). College students' evaluations of teaching and grade inflation. Research in Higher Education, 43(4), 483-501. This study examined the relationship between grades and students’ composite ratings of teaching effectiveness over a 20-year period at a comprehensive, public university in the upper Midwest. Between the spring of 1980 and the fall of 1999, students in more than 37,...
