The most important limitation associated with the clinical use of cyclosporine is the narrow therapeutic range between its efficacy and toxicity. Effective treatment is further complicated by significant variation in intrapatient and interpatient pharmacokinetics of the drug. We describe a practical approach to pharmacokinetic analysis that does not interfere with the cyclosporine dosage regime...
Belgian Blue (BB) cattle are very sensitive to mange caused by Psoroptes ovis and, in contrast to the case in Holstein cattle, single treatments with ivermectin do not result in complete elimination of the parasite. The objective of the present study was to determine the concentration of ivermectin in plasma, skin and hair following subcutaneous administration to Holstein and BB calves and to a...

E-mail address: [email protected] The residence time of a diffusing particle in a prescribed spatial region recently finds an increasing number of applications in physics and chemistry. A partial differential equation for the residence time moments is derived, as a generalization of the ...
This paper reports the effect of superficial liquid mass flow rate and bed void fraction on the pressure drop, dynamic liquid hold-up, mean liquid residence time and biofilm wetting, in a co-current down-flow xylene-removing trickle bed air biofilter (TBAB). The gas–liquid pressure drop increased with liquid mass flow rate and it also increased with diminishing bed void fraction, the effect bei...
[1] We perform the first analysis of stratosphere-troposphere exchange in terms of distributions that partition the one-way flux across the thermal tropopause according to stratospheric residence time t and the regions where air enters and exits the stratosphere. These distributions robustly quantify one-way flux without being rendered ill defined by the short-t eddy-diffusive singularity. Diag...
