Selenium deficit and metabolism

Varna Medical Forum, 2016
Селенът е есенциален микроелемент относно нуждите на човешкия организъм. Като такъв неговият дефицит оказва влияние върху различни метаболитни процеси и се свързва с различни болестни състояния. Приемането му под формата на селеноцистеин и селенометионин съществено повлиява биохимичната картина при заболявания на щитовидната жлеза, като начина на ...

Bioenergetic Materials for Tissue Regeneration: Modulating Metabolism to Promote Cellular Anabolism

Advanced Science, EarlyView.
Bioenergetic materials (BEMs) modulate cellular metabolism to promote tissue regeneration. Their principal mechanisms of action include metabolic substrate supplementation, metabolic enzyme modulation, organelle transfer, electrical current regulation, redox homeostasis modulation, and oxygen tension modulation.

Conjugated Polymer‐Microbe Interactions Trigger Regulatory Reprogramming for Enhanced Bioelectrocatalysis

Advanced Science, EarlyView.
Conjugated polymer‐supported bioelectrochemical systems are shown to enhance microbial electrosynthesis by triggering coordinated electrochemical, transcriptional, post‐transcriptional (sRNA), metabolic, and protein‐level responses. Integrated multi‐omics and electrochemical analyses reveal selective physiological remodeling associated with improved ...

Selenium-Enriched E. coli Bacteria Mitigate the Age-Associated Degeneration of Cholinergic Neurons in C. elegans

Antioxidants
Selenium (Se) is an essential trace element for humans and animals, but high-dose supplementation with Se compounds, most notably selenite, may exert cytotoxic and other adverse effects. On the other hand, bacteria, including Escherichia coli (E.

Selenomethionine metabolism and its toxicity in yeast

Biomolecular Concepts, 2013
The importance of selenium for organisms can be explained by its existence as selenocysteine in the catalytic centers of glutathione peroxidase and thioredoxin reductase. Another selenoamino acid, selenomethionine, is the major form of selenium in foods,

A ROS‐Responsive and Mucoadhesive Thermosensitive Hydrogel Encapsulated with Mizoribine for Synergistic Dry Eye Therapy

Advanced Science, EarlyView.
The ROS‐responsive in situ thermosensitive MZR@SPPP hydrogel system enables dual‐stage drug loading and sustained ocular delivery. Upon administration, it gelates at ocular surface temperature, enhancing ocular adhesion. By scavenging free radicals, restoring NRF2‐mediated antioxidant defense and mitochondrial homeostasis, and suppressing inflammatory ...
