Tracer methods for VLDL-TG kinetics vary in their ability to account for the effect of tracer recycling, which can influence the calculation of VLDL-TG fractional catabolic rates (FCRs). We evaluated a novel approach, involving stable isotopically labeled glycerol or palmitate tracers in conjunction with compartmental modeling, for measuring VLDL-TG kinetics in normolipidemic human subjects. Wh...

Linear compartmental analysis was applied to lacrimal scintigraphy data from asymptomatic and obstructed lacrimal systems. Failure to achieve satisfactory results in most of the asymptomatic systems studied suggests that variable tear flow is a feature of normal lacrimal drainage which precludes linear analysis. However, in cases where the analysis was successful the results were consistent wit...

The analysis of dynamic positron emission tomography (PET) studies provides clinically useful parametric information, but often requires complex and timeconsuming compartmental or non-compartmental techniques. Independent component analysis (ICA), a statistical method used for feature extraction and signal separation, is applied to dynamic PET studies to facilitate the initial interpretation an...

The pharmacokinetics of levamisole was studied in 20 broiler breeder chickens (chickens that give eggs to breed broilers). A single dose of levamisole (40 mg/kg) was administered orally or intravenously to chickens before the onset of egg production, prelay (age = 22 weeks), and repeated at the peak of egg production (age = 32 weeks). A high-pressure liquid chromatographic with ultraviolet dete...

Due to a lack of plausible kinetic modeling for contaminant attenuation, this study first proposed “bi-exponential disposition” model demonstrate the feasibility wide-ranging applications biotic and abiotic degradation pollutant(s).

[1] A compartmental modeling approach is presented to route nitrate retention along a cascade of stream reach sections. A process transfer function is used for transient storage equations with first-order reaction terms to represent nitrate uptake in the free stream and denitrification in the storage regions. In the context of a short-term nitrate injection we define nitrate assimilative capaci...

This article considers simulation and analysis of incidence data using stochastic compartmental models in well-mixed populations. Several approaches are described compared. Thereafter, we provide an overview likelihood estimation for models. We apply one such method to a real-life outbreak set compare assuming different kinds stochasticity. also give references other publications where detailed...
