Abstract Calcium phosphate bioceramics have been studied as bone filler materials for years and become a component of many commercial products. It is widely known that surface-reactive biomaterials may cause changes in the concentration crucial ions surrounding environment, thereby affecting cell metabolism viability. The aim this study was to produce five cement-type characterize their phase composition using X-ray diffraction method, porosity pore size distribution mercury intrusion...
Calcium phosphate cements (CPC) are valuable bone fillers. Recently they have been also considered as the basis for drug-, growth factors- or cells-delivery systems. Broad possibilities to manipulate CPC composition provide a unique opportunity obtain materials with wide range of physicochemical properties. In this study we show that significantly influences cell response. Human derived cells were exposed several well-characterized different based on calcium phosphates, magnesium phosphates...
This study regards the effect of technological aspects on mat compression during manufacturing low-density particleboards made two low density species - i.e. poplar and pine. Using these materials, three-layer (500 kg/m3) were prepared. Three series manufactured: (1) neat pine, (2) poplar-pine (face layer core layer, respectively) (3) boards. Measurements real-time variations in temperature, pressure, thickness allowed for analysis compaction. Selected mechanical properties (modulus rupture,...
In this work, the influence of liquid phase composition on physicochemical properties double hybrid-type bone substitutes was investigated. The solid obtained biomicroconcretes composed highly reactive α-tricalcium phosphate powder (α-TCP) and hybrid hydroxyapatite/chitosan granules (HA/CTS). Various combinations disodium (Na2HPO4) solution citrus pectin gel were used as phases. novelty study is development double-hybrid materials with a dual setting system. phenomenon due to interactions...
Nowadays successful regeneration of damaged bone tissue is a major problem the reconstructive medicine and engineering. Recently great deal attention has been focused on calcium phosphate cements (CPCs) as effective fillers. Despite number studies regarding CPCs, only few compare physicochemical biological properties α-TCP based materials various phase compositions. In our study we compared effect several components (calcite, hydroxyapatite doped with Mg2+, CO32- or Ag+ ions, alginate,...
Recently, intensive efforts have been undertaken to find new, superior biomaterial solutions in the field of hybrid inorganic–organic materials. In our studies, biomicroconcretes containing hydroxyapatite (HAp)–chitosan (CTS) granules dispersed an α tricalcium phospahate (αTCP) matrix were investigated. The influence CTS content and size on physicochemical properties final bone implant materials (setting time, porosity, mechanical strength, phase composition) evaluated. obtained found be...
Bioactive, chemically bonded bone substitutes with antibacterial properties are highly recommended for medical applications. In this study, biomicroconcretes, composed of silicon modified (Si-αTCP) or non-modified α-tricalcium phosphate (αTCP), as well hybrid hydroxyapatite/chitosan granules and gold nanoparticles (AuNPs), were designed. The developed biomicroconcretes supposed to combine the dual functions activity defect repair. chemical phase composition, microstructure, setting times,...
Implantations in orthopedics are associated with a high risk of bacterial infections the surgery area. Therefore, biomaterials containing antibacterial agents, such as antibiotics, bactericidal ions or nanoparticles have been intensively investigated. In this work, silver decorated β tricalcium phosphate (βTCP)-based porous scaffolds were obtained and coated biopolymer—poly(3-hydroxybutyrate)-P(3HB). To best our knowledge, studies using silver-doped βTCP P(3HB), component ceramic-polymer for...
The incidence of gastric cancer (GC) is expected to increase 1.77 million cases by 2040. To improve treatment outcomes, GC patients are increasingly treated with neoadjuvant chemotherapy (NAC) prior curative-intent resection. Although NAC enhances locoregional control and comprehensive patient care, survival rates remain poor, further investigations should establish outcomes assessment current clinical pathways. Individually assessed parameters have served as benchmarks for quality in the...
Materials based on highly reactive α-tricalcium phosphate (α-TCP) powder were developed and evaluated. Furthermore, the impact of different polymeric additives, such as citrus pectin or polyacrylamide (PAAM) modified with sago starch, neem flower, rambutan peel, physiochemical biological properties materials was assessed. The addition PAAM shortened setting process bone cements decreased their compressive strength. On other hand, significantly enhanced mechanical strength material from 4.46...
A procedure for rapidly modifying beech wood using a thermally initiated solvent-free grafting system was examined. In the modification, butyl acrylate and methacrylate were used as vinyl monomers. Free radicals generated from 2,2′-azobis(2-methylpropionitrile) or benzoyl peroxide at 103 180 °C by contact heating of modified material. Chemical changes in material investigated FTIR X-ray photoelectron spectroscopies. The modification resulted decreased surface wetting manifested increased...
