Polyhydroxybutyrate (PHB) tubular scaffolds for nerve regeneration
Introduction Peripheral nerve injuries remain a challenge in regenerative medicine. Biocompatible polymer tubular nerve guides (GNTs) have been shown to be a promising strategy in the regeneration of total nerve disruption injuries (neurotmesis). The purpose of this systematic literature review was to search and

A Closer Look on the Polyhydroxybutyrate- (PHB-) Negative Phenotype of Ralstonia eutropha PHB-4
The undefined poly(3-hydroxybutyrate)- (PHB-) negative mutant R. eutropha PHB-4 was generated in 1970 by 1-nitroso-3-nitro-1-methylguanidine (NMG) treatment. Although being scientific relevant, its genotype remained unknown since its isolation except a recent first investigation.

Microstructure and Properties of Polyhydroxybutyrate-Chitosan-Nanohydroxyapatite Composite Scaffolds
Polyhydroxybutyrate-chitosan-hydroxyapatite (PHB-CHT-HAP) composite scaffolds were prepared by the precipitation of biopolymer-nanohydroxyapatite suspensions and following lyophilisation.

Orthopedic implant of a polyhydroxybutyrate (PHB) and hydroxyapatite composite in cats
The purpose of this study was to evaluate the tissue response to a 70% polyhydroxybutyrate and 30% hydroxyapatite composite in the form of a bone implant, placed intracortically in the distal metaphyseal of the right femur, and subcutaneous implants in cats. Samples of the composite were implanted subcutaneously in the dorsolumbar region and the distal

Polyhydroxybutyrate as a Prebiotic: Mechanisms of Action, Optimization of Fermentation Production, and Food Application [PDF]
Polyhydroxybutyrate (PHB) is an important lipophilic carbon-based energy storage polymer in microbial cells. It is biodegradable and biocompatible, serving as a new type of prebiotic, also known as a “ketogenic substance”.
