Investigating the anti-bioadhesion properties of short, medium chain length, and amphiphilic polyhydroxyalkanoate films. BIOFOULING 2024; 40:177-192.

Abstract
Silicone materials are widely used in fouling release coatings, but developing eco-friendly protection via biosourced coatings, such as polyhydroxyalcanoates (PHA) presents a major challenge. Anti-bioadhesion properties of medium chain length PHA and short chain length PHA films are studied and compared with a reference Polydimethylsiloxane coating. The results highlight the best capability of the soft and low-roughness PHA-mcl films to resist bacteria or diatoms adsorption as compared to neat PDMS and PHBHV coatings. These parameters are insufficient to explain all the results and other properties related to PHA crystallinity are discussed. Moreover, the addition of a low amount of PEG copolymers within the coatings, to create amphiphilic coatings, boosts their anti-adhesive properties. This work reveals the importance of the physical or chemical ambiguity of surfaces in their anti-adhesive effectiveness and highlights the potential of PHA-mcl film to resist the primary adhesion of microorganisms.

Abstract
The needs of modern regenerative medicine for biodegradable polymers are wide and varied. Restoration of the viability of the vascular tree is one of the most important components of the preservation of the usefulness of organs and tissues. The creation of vascular implants compatible with blood is an important task of vascular bioengineering. The function of the endothelial layer of the vessel, being largely responsible for the development of thrombotic complications, is of great importance for hemocompatibility. The development of surfaces with specific characteristics of biomaterials that are used in vascular technologies is one of the solutions for their correct endothelialization. Linear polyhydroxyalkanoates (PHAs) are biodegradable structural polymeric materials suitable for obtaining various types of implants and tissue engineering, having a wide range of structural and physicomechanical properties. The use of PHA of various monomeric compositions in endothelial cultivation makes it possible to evaluate the influence of material properties, especially surface characteristics, on the functional state of cells. It has been established that PHA samples with the inclusion of 3-hydroxyhexanoate have optimal characteristics for the formation of a human umbilical vein endothelial cell, HUVEC, monolayer in terms of cell morphology as well as the levels of expression of vinculin and VE-cadherin. The obtained results provide a rationale for the use of PHA copolymers as materials for direct contact with the endothelium in vascular implants.

Abstract
Biodegradable and biocompatible polymers are actively used in tissue engineering to manufacture scaffolds. Biomedical properties of polymer scaffolds depend on the physical and chemical characteristics and biodegradation kinetics of the polymer material, 3D microstructure and topography of the scaffold surface, as well as availability of minerals, medicinal agents, and growth factors loaded into the scaffold. However, in addition to the above, the intrinsic biological activity of the polymer and its biodegradation products can also become evident. This review provides studies demonstrating that scaffolds made of poly(3-hydroxybutyrate) (PHB) and its copolymers have their own biological activity, and namely, osteoinductive properties. PHB can induce differentiation of mesenchymal stem cells in the osteogenic direction in vitro and stimulates bone tissue regeneration during the simulation of critical and non-critical bone defects in vivo.

Circular RNA PPP1CC promotes Porphyromonas gingivalis-lipopolysaccharide-induced pyroptosis of vascular smooth muscle cells by activating the HMGB1/TLR9/AIM2 pathway.

Abstract
Objective Porphyromonas gingivalis (Pg) plays a
critical role in the occurrence and development of atherosclerosis.
Lipopolysaccharide from Pg (Pg-LPS) could
lead to pyroptosis of vascular smooth muscle cells (VSMCs) and induce
instability of atherosclerotic plaque. Therefore, pyroptosis of VSMCs could
promote the process of atherosclerosis. However, the exact mechanism of
Pg-LPS-induced pyroptosis of VSMCs is unclear. Methods We determined pyroptosis and expression of interleukin (IL)-1β and IL-18 in
VSMCs using 4′,6-diamidino-2-phenylindole staining and ELISA after
stimulation by Pg-LPS. We established a knockdown plasmid
containing the circular (circ)RNA PPP1CC and transfected it into VSMCs.
Luciferase assays were performed to reveal the association between microRNAs
miR-103a-3p and miR-107 and circRNA PPP1CC. Results Stimulation of Pg-LPS led to pyroptosis of VSMCs. Knockdown
of circRNA PPP1CC relieved the Pg-LPS-induced pyroptosis of
VSMCs and suppressed the expression of HMGB1,
TLR9, AIM2, and cleaved caspase-1.
Luciferase assays showed that PPP1CC directly targeted and competitively
adsorbed miR-103a-3p and miR-107, weakening the inhibitory effect of these
microRNAs on the expression of HMGB1. Conclusion Knockdown of circRNA PPP1CC relieved Pg-LPS-induced
pyroptosis of VSMCs. Pyroptosis of VSMCs appears to promote atherosclerosis
and may represent a novel therapeutic target for its treatment.
