Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

Advanced Functional Materials, EarlyView.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

Assessing the function of the alternative electron transport chain in the Cryptosporidium parvum mitosome

mBio
Cryptosporidium parvum and C. hominis possess a remanent mitochondrion called the mitosome, which lacks DNA, the tricarboxylic acid cycle, a conventional electron transport chain, and ATP synthesis. The mitosome retains ubiquinone and iron-sulfur cluster

The participation of cyanide-resistant respiration in heat generation and antioxidative defense of cell in winter wheat shoots under cold influence [PDF]

Journal of Stress Physiology & Biochemistry, 2011
It was shown, that activation of the cyanide-resistant respiration by treatment of 30 mkM antimycine A and 10 mM hydrogen peroxide during 24 hours induced the intensification of heat generation by tissues of winter wheat shoots and decreased death of ...

Involvement of a G Protein Regulatory Circuit in Alternative Oxidase Production in Neurospora crassa

G3: Genes, Genomes, Genetics, 2019
The Neurospora crassa nuclear aod-1 gene encodes an alternative oxidase that functions in mitochondria. The enzyme provides a branch from the standard electron transport chain by transferring electrons directly from ubiquinol to oxygen.

Trypanosome alternative oxidase as a target of chemotherapy

Biochimica et Biophysica Acta (BBA) - Molecular Basis of Disease, 2002
Parasites have developed a variety of physiological functions necessary for their survival within the specialized environment of the host. Using metabolic systems that are very different from those of the host, they can adapt to low oxygen tension present within the host animals.

4D Mapping of ZIF Biocomposites for High Protein Loading and Tunable Release Profiles

Advanced Functional Materials, EarlyView.
Systematic four‐dimensional mapping of zeolitic imidazolate framework biocomposites reveals how precursor ratios, total concentration, and washing define crystalline phase, protein loading, and release kinetics. This comprehensive study identifies conditions yielding record loading (∼85%) and precise phase–property correlations.

Genomic structure and expression of alternative oxidase genes in legumes.

Plant, Cell and Environment, 2018
Mitochondria isolated from chickpea (Cicer arietinum) possess substantial alternative oxidase (AOX) activity, even in non-stressed plants, and one or two AOX protein bands were detected immunologically, depending on the organ. Four different AOX isoforms

[Alternative oxidase - never ending story].

Postepy biochemii, 2017
Investigations of plant cyanide resistant respiration lead to the discovery in mitochondrial respiratory chain of the second terminal oxidase, alternative oxidase (AOX). AOX transfers electrons from reduced ubiquinone to oxygen omitting two coupling places thus lowering energetic efficiency of respiration.

Oral Dosed Organo‐Silica Nanoparticles Restore Glucose Homeostasis and β‐Cell Function in Diabetes Rats

Advanced Functional Materials, EarlyView.
An oral nanoplatform, MOP@T@D, which can maintain glucose homeostasis and restore islet β cells in diabetic rats is developed. It achieves efficient intestinal absorption and liver‐targeted delivery. The nanoparticle disintegrates only in response to hyperglycemia to release insulin on demand and provides antioxidant protection through selenoprotein ...
