β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

open access: yesAdvanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Comprehensively active condensed water from vapors of plasmon-activated water

Chemical Engineering Journal, 2021
Abstract Water is the most environmentally friendly solvent, but bulk water is conventionally considered to be a bystander in reactions performed in it. For decades, scientists have been discussing the characteristics of water that differ from bulk water in special environments.

ACTIVE RENAL WATER EXCRETION

The Lancet, 1967
Abstract Water-loading experiments on normal young adults support the view that active water excretion by the kidneys helps to maintain the constancy of extracellular osmolality.

Water activity and pseudo-activity coefficient of sorbed water

Journal of Food Engineering, 1990
Abstract The sorption isotherm can be represented by a plot of the logarithm of a pseudo-activity coefficient log f′ = loga w − log W against W, the weight of water per 100 g of dried substance. This plot demonstrates the polyphasic behaviour of the system. With reference to the curve for a w = 1, the chemical potentials Δμ Φ for the first

Water Activation for Boosting Electrochemiluminescence

Angewandte Chemie International Edition, 2023
AbstractIn conventional luminol electrochemiluminescence (ECL) systems, hydrogen peroxide and dissolved oxygen are employed as typical co‐reactants to produce reactive oxygen species (ROS) for efficient ECL emission. However, the self‐decomposition of hydrogen peroxide and limited solubility of oxygen in water inevitably restrict the detection accuracy

Water Activity of Mammalian Tissues

Nature, 1958
SINCE the original report by Sabbatani1 that the freezing-point depression of various dog tissues is on the average 150 per cent greater than that of blood, there has been continued interest in the possibility that intracellular fluid is hypertonic to extracellular fluid.

Active Thermochemical Tables: Water and Water Dimer

The Journal of Physical Chemistry A, 2013
A new partition function for water dimer in the temperature range 200-500 K was developed by exploiting the equations of state for real water vapor, liquid water, and ice, and demonstrated to be significantly more accurate than any proposed so far in the literature.
