Water Permeates and Plasticizes Amorphous Carbon Dots: Unraveling the Inner Accessibility of the Nanoparticles by Glass Transition Studies

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
The water permeability of amorphous carbon dots (CDs) is demonstrated by investigating their plasticization. Novel polyamide‐based and amorphous nanoparticles are synthesized by controlling their inner packing density. Water plasticization is evidenced by the decrease of the CDs glass transition temperature with increasing the hydration degree.

Polyamine Oxidase from Water Hyacinth [PDF]

Plant Physiology, 1987
Polyamine oxidase was purified to homogeneity from leaves of water hyacinth by the criterion of sodium dodecyl sulfate gel electrophoresis (SDS disc PAGE). The enzyme showed a high specificity for spermidine and spermine (K(m) values 28 micromolar and 20 micromolar, respectively).

Yeast cytochrome c oxidase: a model system to study mitochondrial forms of the haem-copper oxidase superfamily. [PDF]

, 2012
The known subunits of yeast mitochondrial cytochrome c oxidase are reviewed. The structures of all eleven of its subunits are explored by building homology models based on the published structures of the homologous bovine subunits and similarities and ...

Cytotoxic Effects of Medicinal Plant Extracts on HeLa Cells via Redox Imbalance, L‐Arginine Metabolic Reprogramming, and Glycolytic Suppression

Cell Biochemistry and Function, Volume 44, Issue 9, September 2026.
ABSTRACT Cancer cells undergo metabolic reprogramming to sustain proliferation, resist apoptosis, and adapt to oxidative stress. In the present study, we comparatively evaluated the anticancer effects of four medicinal plant extracts (Inula helenium, Hypericum alpestre, Rumex obtusifolius, and Alchemilla smirnovii) on HeLa cervical cancer cells, with ...

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.

Characterization of Human Polyamine Oxidase

The FASEB Journal, 2015
Polyamine Oxidase (PAO) is a flavoprotein that is necessary for the catabolism of polyamines. PAO oxidizes the endo carbon nitrogen bonds of N1‐acetylspermine and N1‐acetylspermidine when oxidized to spermine and spermidine, respectively. Normal levels of polyamines are needed for cell growth,

Crystallization and preliminary X-ray analysis of polyamine oxidase from Zea mays L.

, 1998
Polyamine oxidase catalyses the oxidation of the secondary amino group of spermine, spermidine and their acetyl derivatives. The enzyme plays an important role in the regulation of polyamine intracellular concentration and is a member of the family of ...
