Food availability and daily biological rhythms
Neuroscience & Biobehavioral Reviews, 1980Restricted daily feeding schedules result in the partial or complete synchronization of a wide range of rhythmic biological functions in rodents. In some cases, exemplified by drinking behavior and liver tyrosine transaminase activity, this represents primarily a direct, exogenous influence of food intake.

Biological availability of inhaled fluticasone propionate in horses
Veterinary Record, 2004Healthy horses received aerosolised, intranasal or oral doses of 3 mg of fluticasone propionate evenly divided over morning and evening treatments for seven days. The bioavailability of the drug was determined in terms of the suppression of the endogenous cortisol concentrations in the horses during the period of treatment.

Biological availability of aluminum in commercial ATP
Journal of Inorganic Biochemistry, 1996Abstract Aluminum is a contaminant of commercial ATP. We have used the fluorescent chelation agent morin to define the conditions of solution pH and incubation period under which this contaminating aluminum was biologically available. The biological significance of our model ligand morin was tested in media in which the morin was replaced with the ...

Commercial availability of biological control agents.
2003The commercial use of biological control has seen a very fast development during the past 30 years. Currently, about 85 companies worldwide produce more than 125 species of natural enemies. The largest variety of commercially produced species of natural enemies is available in Europe, mainly as a result of a much larger greenhouse industry in Europe ...

Assessment of the biologic availability of tetracycline products in man
Clinical Pharmacology & Therapeutics, 1972Significant differences were found in the absorption characteristics of three commercial tetracycline preparations. These differences were observed after both single‐dose and multiple‐dose administration. The relative amount of tetracycline absorbed (biological availability) but not the relative rate of absorption was greater for a standard preparation

Biological availability of endogenous calcitonin in rats
Bulletin of Experimental Biology and Medicine, 1998Significant correlation was established in 52-week-old rats between serum calcitonin content and density of sublemmal granules at the vascular pole of C-cells (N Vsg)∶r xy=0.922 ...

Available biological treatments for complex non-unions
Injury, 2007The treatment of complex non-unions may be lengthy and very expensive. The majority of aseptic non-union cases require a variable degree of biological enhancement. Autologous iliac crest bone graft remains the gold standard of treatment. However, other means of biological stimulation are currently available in the armamentarium of the treating ...

Biological assay for zinc availability in wheat germ
Science of The Total Environment, 1983Our objective was to develop a method to determine the bioavailability of zinc in wheat germ. Weanling rats were fed for 10 days a Zn-free diet supplemented with different levels of Zn, with or without 2% wheat germ. Zinc concentrations of either tibia or femurs were plotted directly against Zn added to the diet, giving two lines that were essentially ...
