Glucosamine oral bioavailability and plasma pharmacokinetics after increasing doses of crystalline glucosamine sulfate in man.
Glucosamine is bioavailable after oral administration of crystalline glucosamine sulfate, persists in circulation, and its pharmacokinetics support once-daily dosage.
Anthraquinone profile and chemical fingerprint of Rhamnus saxatilis L. from Italy
Abstract Several species belonging to the genus Rhamnus (Rhamnaceae), comprising ones among which are found the most typical plants of the Italian flora, are known to contain biologically active
Analytical methods for the endocrine disruptor compounds determination in environmental water samples.
In this review, several sample pretreatment protocols, assays and different instrumental techniques recently used in the EDCs determination have been considered, highlighting their sensitivity and selectivity for the analyses of environmental water samples.
Chemical composition and biological activities of extracts from three Salvia species: S. blepharochlaena, S. euphratica var. leiocalycina, and S. verticillata subsp. amasiaca
Abstract The genus Salvia has recently attracted great attention due to its notable biological activities. Within this context, in this study, the chemical characterization and biological effects of
Synovial and plasma glucosamine concentrations in osteoarthritic patients following oral crystalline glucosamine sulphate at therapeutic dose.
Glucosamine is bioavailable both systemically and at the site of action (the joint) after oral administration of crystalline glucosamine sulphate in ostaeoarthritis patients.
