Massic activity ratios of the NBS/NIST tritiated-water standards issued between 1954 and 1999

open access: yes, 2000
As part of the preparation and calibration of three new National Institute of Standards and Technology (NIST) tritiated-water radioactivity Standard Reference Materials (SRMs), the massic-activity (activity of the sample divided by the mass of the sample)

Influence of the structure of a mineral adsorbent on the detritization of aqueous solutions

open access: yesВісник Харківського національного університету імені В.Н. Каразіна. Серія Геологія. Географія. Екологія, 2021
Introduction. Formed in a nuclear reactor, tritium is mainly discharged into the hydrosphere. A significant part of tritium also enters the environment during the reprocessing of spent nuclear fuel. Currently, the problem is the development of effective,

SYNTHESIS AND STORAGE OF SMALL QUANTITIES OF TRITIATED WATER [PDF]

open access: yes, 1957
A method that can be used to produce milliliter amounts of tritiated water from tritium gas is described. Safety precautions are emphasized as part of the method, which involves oxidation of tritium gas over hot copper(II) oxide in a sealed glass system.

The Uptake of Ethinyl-Estradiol and Cortisol From Water by Mussels (Mytilus spp.)

open access: yesFrontiers in Endocrinology, 2021
Previous toxicokinetic studies have shown that mussels (Mytilus spp.) can readily absorb the three main mammalian sex steroids, estradiol (E2), testosterone (T) and progesterone (P) from water.

The use of tritiated water in livestock research in Africa: Theory, application, methodology and potential errors of the technique [PDF]

open access: yes, 2011
Presents a theoritical outline of the techniques in the use of tritiated water (HTO) which can be used to estimate total body water, body composition, water turnover, milk intake and feed intake.

Optical Control of the Glucocorticoid Receptor Activity With a Photoswitchable Agonist

open access: yesAngewandte Chemie International Edition, EarlyView.
A photoswitchable glucocorticoid receptor agonist enables optical control of receptor activity, achieving picomolar potency and partial agonism that preferentially maintains anti‐inflammatory signaling over canonical transcriptional activation. ABSTRACT Glucocorticoids (GCs) are widely prescribed anti‐inflammatory agents whose clinical utility is ...

Measurement of rates of cholesterol synthesis using tritiated water

open access: yesJournal of Lipid Research, 1984
Rates of sterol synthesis in various tissues commonly are assessed by assaying levels of 3-hydroxy-3-methylglutaryl CoA (HMG-CoA) reductase on isolated microsomes or by measuring the rates of incorporation of various 14C-labeled substrates or [3H]water ...

The in vitro permeability of skin and buccal mucosa to selected drugs and tritiated water.

open access: yesJournal of Investigative Dermatology, 1976
The permeability of whole human skin, human dermis, whole pig skin, and canine buccal mucosa have been determined for four chemically different solutes: tritiated water, amphetamine, estradiol, and ouabain.

Histamine and the mechanisms of nausea and vomiting: Translating the uncertain pharmacology of cyclizine

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Abstract Cyclizine is a long‐established, short‐acting drug, registered for preventing motion sickness, post‐operative nausea and vomiting (PONV) and ‘vomiting of known cause’. The latter is not defined but may include pregnancy and patients receiving palliative care, historically accepted without large, controlled trials.
