Daily variations in ceftriaxone pharmacokinetics in rats.
The aim of this study was to determine whether the time of day ceftriaxone was administered modified its pharmacokinetics. Ceftriaxone was given intraperitoneally at either 0400, 1000, 1600, and 2200 h to Sprague-Dawley rats synchronized under a light-dark cycle of 12 h of light and 12 h of dark. Pharmacokinetic parameters were analyzed for the presence of a 24-h rhythm. Results showed signific...
متن کاملCompost and biochar alter mycorrhization, tomato root exudation, and development of Fusarium oxysporum f. sp. lycopersici
Soil amendments like compost and biochar are known to affect soil properties, plant growth as well as soil borne plant pathogens. Complex interactions based on microbial activity and abiotic characteristics are supposed to be responsible for suppressive properties of certain substrates, however, the specific mechanisms of action are still widely unknown. In the present study, the main focus was...
متن کاملVariations in Fleshiness of Tomato Fruits as Affected by Fertilization.
The evaluation of quality in agricultural products affords many research problems. Primarily, there is the difficulty of defining quality factors and the worker does well to confine his efforts to those correlated with very concrete morphological or chemical differences which are easily measureable. The variations in quality which are noted by consumers may be caused by conditions existing duri...
