Fish may use lipoproteins instead of albumin-bound fatty acids to fuel endurance exercise, but lipoprotein kinetics have never been measured in ectotherms. In vivo bolus injections of labeled very-low-density lipoproteins ((3)H-VLDL labeled in vivo from donor fish) and continuous infusions of Intralipid (3H-labeled artificial emulsion) were used to investigate the effects of prolonged exercise ...

Due to the rapid turnover of the small intestinal epithelia, the rate at which enterocyte renewal occurs plays an important role in determining the level of drug-metabolizing enzymes in the gut wall. Current physiologically based pharmacokinetic (PBPK) models consider enzyme and enterocyte recovery as a lumped first-order rate. An assessment of enterocyte turnover would enable enzyme and entero...

conclusions results indicated that annular fluidized bed reactor’s adsorbers are useful techniques for vocs adsorption. comparison of two particle ranges indicates that in all concentrations and all flow rates of the experiments, smaller particle size adsorption are better. in superficial velocity above the minimum fluidization velocity, pressure drop of fluidized beds are less than the pressur...

Ammonium perchlorate particles have been dried in a laboratory spouted bed dryer (screen-bottomed type) which is categorized as a fluidized bed dryer. The solid particles obtained in this process of drying were semi-porous and known as the group D of Geldart classification. The variations of moisture content with resident time, the effects of bed height on the pressure dro...

The aim of this study is to (i) determine the turnover rate among registered nurses in Jordanian hospitals; and (ii) compare the turnover rate between (a) male and female registered nurses; (b) northern, middle and southern regions; (c) public, private and university hospitals; (d) rural and urban hospitals; and (e) general and specialized hospitals. A descriptive, cross-sectional retrospective...

THE PULSE RATE during and after exercise has been utilized in a number of ways to assess unfitness.1 16 The simplest method has been to measure the pulse rate at specified times after effort and to record the time taken for the pulse rate to return to the resting level. Alternatively, the pulse rate has been measured during exercise. In both instances, unfitness has been judged by the degree to...

The endogenous noradrenaline concentration, fractional turnover, half-life, and turnover rate of tritiated ((3)H) noradrenaline were determined in the oesophagus, non-glandular and glandular portions of the stomach, duodenum, jejunum, ileum, and colon of the rat. The highest concentration of endogenous noradrenaline was present in the duodenum and colon. The (3)H-noradrenaline fractional turnov...
