Dualsteric and dual‐acting modulation of muscarinic receptors by antagonist KH‐5

open access: yesBritish Journal of Pharmacology, Volume 183, Issue 19, Page 5769-5790, October 2026.
Abstract Background and purpose Muscarinic acetylcholine receptors are key therapeutic targets, and ligands engaging both orthosteric and allosteric sites may offer improved selectivity and efficacy. Here, we investigated whether the muscarinic antagonist KH‐5 acts as a dualsteric antagonist and defined its mode of interaction with muscarinic receptors.

A two-pool model of tritiated water kinetics to predict body composition in unfasted lactating goats

open access: yes, 1988
A two-pool model of tritiated water kinetics was investigated as a means of partitioning total body water into empty body water and gut water in 17 lactating goats.

Mathematical simulations for studying the effectiveness of HTO removal mechanism from spent fuel storage bay and estimating the environmental releases

open access: yesRadiation Protection and Environment, 2019
The diffusion of tritiated water (HTO) vapor from the spent fuel storage bay to the spent fuel storage building (SFSB) may lead to internal exposure to occupational workers.

Water‐Dispersible Ruthenium Nanocatalyst for Carbonyl Reduction With D2 or T2 in Aqueous Media

open access: yesAngewandte Chemie, Volume 138, Issue 38, 14 September 2026.
We report the synthesis and characterization of water‐dispersible ruthenium nanoparticles that catalyze the reductive deuteration and tritiation of carbonyl compounds in aqueous media, enabling efficient access to a broad range of isotopically labeled polar molecules, including cyclic peptides, antibody‐drug conjugate linkers, pegylated derivatives ...

The Exchange of Tritiated Water Between Zn-A Zeolitevand the Surrounding Water [PDF]

open access: yes, 1987
Zeolites are considered as adsorbents for tritiated waste water. The sorption capacity of 4A zeolite is increased, and the speed of tritium release, as THO, decreased if sodium ions in 4A zeolite are replaced with small divalent cations.

On the Diffusion of Tritiated Water Through Skin

open access: yesJournal of Investigative Dermatology, 1968
A recent paper in this journal by Downes et al (1) reported on the use of a simple in vitro method for determining the diffusion of water through skin by measuring the unidirectional flux of tritiated (radioactive water. The method consists in mounting a piece of skin as a barrier between two glass chambers and measuring the appearance of tritiated ...

Quantum‐Level Influences on Enzyme Reactions and Their Ripple Effects on Biological Phenomena

open access: yesAdvanced Physics Research, Volume 5, Issue 9, September 2026.
Because living organisms are ultimately composed of atoms and molecules, quantum‐mechanical effects are expected to contribute to biological phenomena. Quantum biology seeks to elucidate life processes from a quantum‐mechanical perspective. This review discusses how quantum‐level effects, including quantum tunneling, may propagate from enzymatic proton‐

Tritium recovery from tritiated water with a two-stage palladium membrane reactor [PDF]

open access: yes, 1997
A process to recover tritium from tritiated water has been successfully demonstrated at TSTA. The 2-stage palladium membrane reactor (PMR) is capable of recovering tritium from water without generating additional waste. This device can be used to recover

HICU PIE results of neutron-irradiated lithium metatitanate pebbles

open access: yesNuclear Materials and Energy
Lithium metatitanate (Li2TiO3) pebbles were irradiated with neutrons within the HICU (High neutron fluence Irradiation of pebble staCks for fUsion) experiment to investigate their material properties and tritium release behaviour in a post-irradiation ...

Translocation of Sugar and Tritiated Water in Squash Plants [PDF]

open access: yesPlant Physiology, 1968
When (14)C-sugar and THO were simultaneously introduced through a cut side vein or flap of a squash leaf (Cucurbita melopepo, Bailey cv. torticollis) concurrent translocation of (14)C-sugars, T-photosynthates and THO with parallel, almost flat, gradients was observed in the petiole for periods of 1 to 3 hr.
