Some Peculiarities of Foraminifera Species Distribution Associated with Concentrations of ²²⁶Ra,²³⁸U, ²³²Th in the Deryugin Basin (the Sea of Okhotsk) [PDF]

Журнал Сибирского федерального университета: Серия Биология, 2018
An analysis of composition and quantitative distribution of foraminifera in bottom sediments collected in the Deryugin Basin (the Sea of Okhotsk) has demonstrated that specific foraminiferal assemblages at the depths of 691 to 1786 m are associated with ...

Pharmacokinetics, mass balance, tissue distribution, metabolism, and excretion of praliciguat, a clinical‐stage soluble guanylate cyclase stimulator in rats

Pharmacology Research & Perspectives, 2020
The pharmacokinetics (PK), metabolism, excretion, mass balance, and tissue distribution of [14C]praliciguat were evaluated following oral administration of a 3‐mg/kg dose in Sprague‐Dawley rats and in a quantitative whole‐body autoradiography (QWBA ...

Metabolic Study of Tetra-PEG-Based Hydrogel after Pelvic Implantation in Rats

Molecules, 2022
In vivo metabolism of polyethylene glycol (PEG) hydrogels has rarely been studied. In this study, we prepared a chemically crosslinked hydrogel formulation using 14C-labeled tetra-armed poly (ethylene glycol) succinimidyl succinate (Tetra-PEG-SS) and 3H ...

Absorption, storage, and distribution of beta-carotene in normal and beta-carotene-fed rats: roles of parenchymal and stellate cells.

Journal of Lipid Research, 1989
Absorption and storage of [14C]beta-carotene in control and beta-carotene-fed (BC-fed) rats were determined. Pre-feeding with beta-carotene for 2 weeks caused a 1.9-fold stimulation of its own absorption as well as its conversion to retinyl esters ...

Tissue distribution of radioactivity following intranasal administration of radioactive microspheres

Journal of Pharmacy and Pharmacology, 2001
Abstract The aim of this study was to increase understanding of the kinetics of microparticle distribution and elimination following intranasal application. To do this we investigated the in-vivo distribution of radioactivity following intranasal instillation of scandium-46 labelled styrene-divinyl benzene 7-μm-diameter microspheres ...
