Rate of elimination of excess CO2 in humans

Respiration Physiology, 1988
This study examined the ability of the respiratory system of awake normal subjects to correct an acute disturbance in body CO2 stores produced by rebreathing. Thirteen subjects, after 10 min of O2 breathing, rebreathed CO2 for 4 min in order to increase CO2 stores. The rate of CO2 elimination (VelCO2) after rebreathing was measured breath by breath for

The effect of ciclotropium on human heart rate

European Journal of Clinical Pharmacology, 1994
Ciclotropium is a recently developed parasympathicolytic agent. Plasma concentration and heart rate increase (the most prominent anticholinergic effects) were measured in 12 healthy subjects before, during and after a 15-min intravenous infusion of 10 mg ciclotropium.

Limits to sustainable human metabolic rate

Journal of Experimental Biology, 2001
SUMMARYThere is a limit to the performance of an organism set by energy intake and energy mobilization. Here, the focus is on humans with unlimited access to food and for whom physical activity can be limited by energy mobilization. The physical activity level (PAL) in the general population, calculated as doubly-labelled-water-assessed average daily ...

VARIATIONS IN RATE OF HUMAN OSTEON FORMATION

Canadian Journal of Biochemistry and Physiology, 1963
The authors' method depends on labelling in vivo the zone of demarcation of actively forming osteons by tetracycline antibiotics. The drugs, thus deposited in bone, are visualized by fluorescence microscopy. The label is a circular or elliptical ring whose diameter indicates the degree of completeness of the osteon at the time of drug administration ...

Central dogma rates in human mitochondria

Human Molecular Genetics
Abstract In human cells, the nuclear and mitochondrial genomes engage in a complex interplay to produce dual-encoded oxidative phosphorylation (OXPHOS) complexes. The coordination of these dynamic gene expression processes is essential for producing matched amounts of OXPHOS protein subunits.

AVOIDANCE CONDITIONING OF HEART RATE IN HUMANS

Psychophysiology, 1966
ABSTRACTAn avoidance conditioning technique was employed to obtain external control over heart rate. A contingency was set up between heart‐rate maintenance and punishment avoidance. During periods of time signified by a visual stimulus, punishments were dispensed when the total number of beats per minute decreased from the previous minute's total ...

The rate of decline of diphenylhydantoin in human plasma

Clinical Pharmacology & Therapeutics, 1970
The rate of disappearance of diphenylhydantoin from plasma was studied in 70 healthy volunteers by giving them 100 mg. orally 3 times daily for 3 days and measuring the plasma diphenylhydantoin concentration for 4 consecutive days after the last dose of the drug.

Rates of intestinal absorption of molybdenum in humans

Applied Radiation and Isotopes, 2006
The intestinal absorption of molybdenum in healthy human volunteers has been measured by simultaneous oral and intravenous administration of the stable isotopes 95Mo and 96Mo, and the results were analysed using the convolution integral technique. The results showed that molybdenum ingested in liquid form was rapidly and totally absorbed into the ...
