The effects of the inoculum, pH, cation concentrations, and different lots of commercial media on the in vitro susceptibility of Clostridium difficile to fidaxomicin were examined. Of the factors evaluated, only pH alterations influenced the activity of fidaxomicin against C. difficile, noticeably reducing its activity at higher pH (> or =7.9).

Mountain pastures dominated by the pasture grass Setaria sphacelata in the Andes of southern Ecuador are heavily infested by southern bracken (Pteridium arachnoideum), a major problem for pasture management. Field observations suggest that bracken might outcompete the grass due to its competitive strength with regard to the absorption of photosynthetically active radiation (PAR). To understand ...

UNLABELLED In patients with pulmonary hypertension (PH) the right ventricular (RV)-to-left ventricular (LV) ratio of fatty acid uptake is reduced. In animal studies, such a finding was combined with an increased glucose uptake in RV myocardium. The aim of this study was to measure the metabolic rates of glucose uptake for the RV and LV myocardium in patients in relationship to parameters of RV ...

introduction weeds are main factors reducing crops yield, especially under organic farming conditions (). it has been reported that weed populations are more in organic farming compared to conventional cropping systems, resulting in more reduction of growth and yield. although the chemical control is a fast and effective way for controlling weed populations, some negative impacts of the recent ...

Satellite remote sensing of Gross Primary Production (GPP) will greatly enhance our understanding of the terrestrial carbon cycle, as it allows globally continuous estimates of plant CO 2 uptake at regular intervals from space [1]. Remotely sensed GPP can be defined as the product of the incident photosynthetically active radiation (the radiation between 400 and 700 nm wavelength, PAR), the fra...

Wide-narrow row maize planting patterns are a popular way to enhance yield via improving canopy PAR. To further optimize PAR, we designed an improved wide-narrow pattern (R2) based on the principle of shortest projection length and longest illumination objects ground. Compared traditional (R1), increased by about 10% in R2. R2 had higher leaf area index, chlorophyll content, photosynthetic rate...

We use a new construction in the spirit of Gromov’s convex integration to prove a rather surprising result that every affine map is the boundary value of a weakly quasiregular map in any Sobolev space with index p < n/2. Our method is based on constructing special Cauchy sequences by convex integration for certain vectorial Hamilton–Jacobi equations.  2000 Académie des sciences/Éditions scient...
