The development of novel materials with effective defect‐repairing properties will help avoid subtotal gastrectomy in patients with large gastric perforations. We prepared perfused decellularized gastric matrix (PDGM) and analyzed its components, spatial structure, biomechanics, cytotoxicity, and histocompatibility to validate its efficacy in the repair of gastric perforation. PDGM retained large...
The surface properties of titanium and its alloys are commonly modified by different techniques, including additive manufacturing (AM), to improve the osseointegration of dental implants. The aim of this study was to evaluate and compare the wettability, topography, chemistry, and structure of titanium‐aluminum‐vanadium (Ti‐6Al‐4 V) discs fabricated by selective laser melting (SLM) and subtractive...
With antibiotic‐resistant bacteria becoming increasingly prevalent, biomaterials capable of targeted, in situ drug delivery are urgently needed. The synthetic polymer Poloxamer 407 (P407) is of particular interest due to its thermoreversible gelation. Clinical use of P407 typically involves sterilization via autoclaving, but the effects of these extreme environmental conditions on hydrogel water content,...
The purpose of the present work was to investigate the effect doping with lanthanum aluminate on the phase assemblage and thermal behavior of zirconia ceramics for biomedical applications. Four compositions were prepared by a surface modification route of either conventional tetragonal zirconia (3Y‐TZP) or high translucency cubic‐based zirconia (5Y‐PSZ) to reach a nominal composition of either 0.5...
Osseointegration is defined by a stable and functional union between bone and a surface of a material. This phenomenon is influenced by the geometric and surface characteristics of the part where the bone cells will attach. A wide variety of studies proves that ceramic materials are strong competitors against conventional metals in the scope of bone tissue engineering. Ceramic scaffolds, porous structures...
Device manufacturers and regulatory agencies currently utilize expensive and often inconclusive in vivo vascular implant models to assess implant material thrombogenicity. We report an in vitro thrombogenicity assessment methodology where test materials (polyethylene, Elasthane™ 80A polyurethane, Pebax®), alongside positive (borosilicate glass) and negative (no material) controls, were exposed to...
Zinc (Zn) based biomaterials have been emerged as one of the capable biodegradable materials for biomedical applications because of the ideal degradation properties. In the present work, corrosion kinetics of Zn–hydroxyapatite (HA), and Zn–HA–iron (Fe) materials developed using microwave sintering process were investigated. The effect of the inclusion of HA and Fe in Zn on corrosion properties have...
To assess the effect of biodentine (BD) and MTA‐angelus (MTA) on biocompatibility, BMP2, BMP4, and osteocalcin (OC) expression. Subcutaneously implanted tubes of four groups (MTA, BD, Control, and Sham) were kept over 15, 30, and 60 days; histological analyses were performed using H&E and Von Kossa; ELISA quantified IL‐1β and IL‐8 expression; and qRT‐PCR verified gene expression of BMPs and OC...
Auricular reconstruction is a technically demanding procedure requiring significant surgical expertise, as the current gold standard involves hand carving of the costal cartilage into an auricular framework and re‐implantation of the tissue. 3D‐printing presents a powerful tool that can reduce technical demands associated with the procedure. Our group compared clinical, radiological, histological,...
Insertion of a central venous catheter is one of the most common invasive procedures applied in hemodialysis therapy for end‐stage renal disease. The most important complication of a central venous catheter is catheter‐related infections that increase hospitalization and duration of intensive care unit stay, cost of treatment, mortality, and morbidity rates. Pathogenic microorganisms, such as, bacteria...
Internal biliary stenting during biliary reconstruction in liver transplantation decrease anastomotic biliary complications. Implantation of a resorbable internal biliary stent (RIBS) is interesting since it would avoid an ablation gesture. The objective of present work was to evaluate adequacy of selected PLA‐b‐PEG‐b‐PLA copolymers for RIBS aimed to secure biliary anastomose during healing and prevent...
Transarterial chemo‐embolization with drug‐eluting embolic beads (DEB‐TACE) is still evolving. Recent developments include the introduction of radiopaque (X‐ray imageable) drug‐eluting particles. Here, we report on conceptually different radiopaque polymeric drug‐eluting embolic particles, which are (i), cross‐linked poly(methacrylates); (ii), radiopaque; (iii), microporous. Furthermore, the particles...
This study evaluated the biological behavior of the coffee compounds Trigonelline (T), chlorogenic acid (C), and nicotinic acid (N), correlating with their release from a resin matrix. Minimum inhibitory concentration (MIC) was evaluated against Streptococcus mutans UA159, and cytotoxicity was assessed by methyl tetrazolium salt on OD‐21 cells. Resin matrices (bisphenol A‐glycidyl‐dimethacrylate/triethylene...
The cover image is based on the Original Research Report Crystalline phase evolution and thermal behavior of zirconia‐lanthanum aluminate ceramics produced by surface modification by Isabelle Denry, Deborah V. Dawson, and Julie A. Holloway., https://doi.org/10.1002/jbm.b.34702.
