Article Synopsis
  • This paper discusses the creation and organization of polyurethane elastomers using special bis-aromatic urea hydrogen bonding motifs to enhance self-assembly.
  • It details the use of polytetramethylene ether glycol (PTMG) and other diols to form supramolecular polyurethanes with specific molecular weights and distribution.
  • The resulting materials display adjustable mechanical properties and healing capabilities, making them suitable for practical applications like cable coatings.

Degenerative musculoskeletal diseases represent a global health problem due to the progressive deterioration of affected individuals. As a bioactive compound, catechins have shown osteoprotective properties by stimulating osteoblastic cells and inhibiting bone resorption. Thus, this review aimed to address the mechanism of action of catechins on bone tissue.

Epicatechin is a polyphenol compound that promotes skeletal muscle differentiation and counteracts the pathways that participate in the degradation of proteins. Several studies present contradictory results of treatment protocols and therapeutic effects. Therefore, the objective of this systematic review was to investigate the current literature showing the molecular mechanism and clinical protocol of epicatechin in muscle atrophy in humans, animals, and myoblast cell-line.

Fibrin sealants derived from human blood can be used in tissue engineering to assist in the repair of bone defects. The objective of this study was to evaluate the support system formed by a xenograft fibrin sealant associated with photobiomodulation therapy of critical defects in rat calvaria. Thirty-six rats were divided into four groups: BC ( = 8), defect filled with blood clot; FSB ( = 10), filled with fibrin sealant and xenograft; BC ( = 8), blood clot and photobiomodulation; FSB ( = 10), fibrin sealant, xenograft, and photobiomodulation.

The design and synthesis of low molecular weight additives based on self-assembling nitroarylurea units, and their compatibility with poly(ethylene--acrylic acid) copolymers are reported. The self-assembly properties of the low molecular weight additives have been demonstrated in a series of gelation studies. Upon blending at low percentage weights (≤5%) with poly(ethylene--acrylic acid) the additives were capable of increasing the stress and strain to failure when compared to the parent copolymer.
