Informational selection & natural selection
Physics Procedia, 2010 The Natural Selection Principle plays an important role in Darwinian evolution theory for the world of biology; its success and reasoning power have persuaded many people that there should be a similar principle for social, economic phenomena. After all, the current economy is a much faster evolutionary process. Unlike in the history of evolution where

FEBS Letters, EarlyView.We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Ion-imprinted polyaniline-based polymer for selective electrochemical detection of cadmium
Journal of Electrochemical Science and EngineeringAn electrochemical sensor based on ion-imprinted functionalized polyaniline has been fabricated and tested for the electrochemical sensing of cadmium in aqueous solution. The synthesis of the polymer was started by copolymerizing anthranilic acid and 2-

FEBS Letters, EarlyView.We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
