Two healthy men with high working capacities were injected intravenously with palmitate-l-14Cand NaHI4CO3 on two occasions while they were performing strenuous exercise on a bicycle ergometer. From analysis of l4COz in expired air after injection of NaH14C03, rate constants and compartment sizes describing a three-compartment system for COZ were determined algebraically. These data were combine...

PET enables not only visualization of the distribution of radiotracer, but also has ability to quantify several biomedical functions. Compartmental model is a basic idea to analyze dynamic PET data. This review describes the principle of the compartmental model and categorizes the techniques and approaches for the compartmental model according to various aspects: model design, experimental desi...

The endochitinase from barley is the archetypal enzyme for a large class of plant-derived antifungal chitinases. The X-ray structure was solved previously in our laboratory and a mechanism of action proposed based on structural considerations. In this manuscript we report the use of a defined soluble substrate, 4-methylumbelliferyl beta-N,N',N"-triacetylchitotrioside, to characterize kinetic pa...

Combined kinetic analysis has been applied for the first time to the thermal degradation of polymeric materials. The combined kinetic analysis allows the determination of the kinetic parameter from the simultaneous analysis of a set of experimental curves recorded under any thermal schedule. Besides, the method does not make any assumption about the kinetic model or activation energy and allows...

The kinetic approach to the formation of filaments in large-scale matter distribution Universe is considered within Vlasov formalism. structures arise due self-consistent dynamics, along with repulsive term modified Newtonian gravity which includes cosmological constant. That enables one describe Hubble tension as a result two flows, local and global ones. criteria for non--stationary semi-peri...
