Auxin response and PIN‐mediated transport in chlorophyte algae

Journal of Integrative Plant Biology, EarlyView.
Like multicellular plants, green algae respond to auxin and move it across their cells. However, their PIN‐like proteins do not act like plant auxin exporters, suggesting that basic auxin transport evolved early and specialized directional transport appeared later in plant evolution.

Transfer of paracetamol across the placenta and fetal blood–brain barriers and its safety for use in pregnancy

The Journal of Physiology, EarlyView.
Abstract figure legend Paracetamol (acetaminophen) is commonly taken during pregnancy for pain and fever. To gain a more comprehensive understanding of paracetamol's effects during pregnancy, several elements need to be examined including the transfer of paracetamol across the placenta and into the developing brain, the short‐ and long‐term effects of ...

Calibration of tritium enrichment factor in solid-polymer electrolyte device based on correlation between deuterium and tritium

He jishu
BackgroundSolid-polymer electrolyte (SPE) water electrolysis has been widely used to concentrate low-level environmental tritium for measurements. It has the advantages of electrolyte elimination, infinite reduction ratio, high current, safety, and ...

DOSE ASSESSMENT FOR INTAKE OF TRITIATED WATER IN HUMANS: ROLE OF TRITIUM INCORPORATION IN ORGANIC MATTER

Радиационная гигиена, 2017
Tritium is one of the factors of internal exposure of the humans both in occupational and public environments. It enters the body mainly as tritiated water through inhalation, with food, drinks and through the skin; part of tritium gradually transforms ...

Satellite Glial Cells Synthesize and Release GABA to Activate Extrasynaptic GABAA Receptors That Modulate Dorsal Root Ganglia Neuron Excitability

Glia, Volume 74, Issue 9, September 2026.
Mechanism of synthesis, release, receptor activation, uptake, and degradation of GABA in dorsal root ganglia (DRG). Left: GABA is synthesized from putrescine in satellite glial cells (SGCs). After being released by Best1 channel, it activates GABAA receptors in sensory neurons, producing a chloride current.

Tritium Behavior from Vine to Wine

Applied Sciences
The hydrogen radioactive isotope, tritium, not only reflects seasonal variation in precipitation but also variations on a local level. To use this radioisotope in authentication and geographical indication procedures, the tritium levels in vines, grapes,

An ion treatment planning framework for inclusion of nanodosimetric ionization detail through cluster dose

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Nanodosimetry relates the cumulative or statistical moments of Ionization Detail (ID) with biological endpoints of relevance to cancer radiotherapy using charged particles. This association suggests to develop an additional physics‐detailed layer of modeling that may complement biological modeling and treatment planning.

Modern approaches to the determination of organically bound tritium in environmental media and biological tissues

Радиационная гигиена
The prolonged discharge of tritium-containing water from the Fukushima Daiichi Nuclear Power Plant into the Pacific Ocean leads to the gradual transport of tritium into Russian fishing zones and its accumulation in marine products.

Tritium surface contamination [PDF]

The International Journal of Applied Radiation and Isotopes, 1985
Glovebox wipe surveys were conducted to correlate surface tritium contamination with atmospheric tritium levels. Surface contamination was examined as a function of tritium concentration and of tritium form, HT/T2 and HTO. The relationship between atmospheric HTO concentration and cleanup time was also investigated.
