The bioactive glasses can lead to the promotion of growth granulation tissue, while gold nanoparticles (AuNPs) induce acceleration wound healing including tissue regeneration, connective formation, and angiogenesis. aim this study was evaluate impact using glass (BG) BG-AuNPs composites on skin in experimental rat models for 14 days. Sol-gel derived BGs mixed with Vaseline at 6, 12 18 wt% were used repair response skin. During process healing, granulomatous reaction observed treated...
Nano- and micro-sized ZnO spheres were fabricated via a simple solvothermal synthesis using two different precursors, while diethanolamine was used to control the morphology. The applied solvent composition, precursor ratio treatment temperature mathematically correlated with diameter of spheres. crystallite size could be easily controlled by adjusting temperature, providing flexibility during synthesis. photocatalytic activity its dependence on unique morphology investigated decomposition...
In the present study, polysaccharide-based cryogels demonstrate their potential to mimic a synthetic extracellular matrix. Alginate-based cryogel composites with different gum arabic ratios were synthesized by an external ionic cross-linking protocol, and interaction between anionic polysaccharides was investigated. The structural features provided FT-IR, Raman, MAS NMR spectra analysis indicated that chelation mechanism is main process linking two biopolymers. addition, SEM investigations...

The most important concept behind using bone scaffolds is the biocompatibility of material to avoid a local inflammatory response and must have following properties: osteoinduction, osteoconductivity, angiogenesis, mechanical support for cell growth. Gold nanoparticles/gold silver nanoparticles -containing bioactive glasses in biopolymer composites been used enhance regeneration. These were testedin vitroon fibroblast osteoblast lines MTT tests, immunofluorescence, scanning electron...
Rosmarinic acid is a well-known natural antioxidant and anti-inflammatory compound, it one of the polyphenolic compounds found in comfrey plants. Comfrey root also contains allantoin, which helps with new skin regeneration. This study aimed to investigate healing regeneration process wounds Wistar rats using creams based on extract correlate results active extract. The obtained showed that rich bioactive compounds, including salvianolic acid, rosmarinic are known for their great free radical...
The UV-B component of sunlight damages the DNA in skin cells, which can lead to cancer and premature aging. Therefore, it is necessary use creams that also contain UV-active substances. Many sunscreens titanium dioxide due its capacity absorb wavelengths. In present study, titan was introduced alginate chitosan–alginate hydrogel composites are often involved as scaffold compositions tissue engineering applications. Alginate chitosan were chosen their important role regeneration protection....
In the present study, scaffold composites based on alginate-pullulan-bioactive glass‑gold nanoparticles were orthotopically implanted in an experimental model of delayed bone union, rats, given by a metabolic pathology, namely osteoporosis. Differences between treated and untreated groups observed efficacy our biomaterial was evaluated applying micro-CT imaging, together with histological evaluation osteoporotic animals sub-critical defects, at 30 60 days. Osteoporosis successfully induced...
The formation of a calcium phosphate layer on the surface SiO2 -CaO-P2 O5 glasses after immersion in simulated body fluid (SBF) generally demonstrates bioactivity these materials. Grafting by chemical bonding can minimize structural changes protein adsorbed surface. Therefore, this study our interest was to evaluate and blood biocompatibility their modification functionalization with aminopropyl-triethoxysilane and/or fibrinogen. It is shown that fibrinogen glass surfaces induces growing...

Bioactive glasses doped with silver are aimed to minimize the risk of microbial contamination; therefore, influence on bioactive properties is intensely investigated. However, information related role played by silver, when added glass composition, biocompatibility scarce. This aspect essential as long content can blood protein adsorption onto surface glass, thus affecting material's biocompatibility. Therefore, from perspective standpoint, finding an optimal in a extremely important issue....
