BACKGROUND Peritoneal dialysis causes the functional and morphological changes in the peritoneum that result from the bioincompatibility of dialysis solutions. We present a model of chronic peritoneal dialysis in the rat that can be used for testing the biocompatibility of dialysis fluids. Methods and Results. Long-term exposure of the peritoneum to dialysis solutions can be performed in rats w...

Cells and scaffolds belong to main components of tissue engineering. In this study we have performed in vitro cytotoxicity and biocompatibility testing of modified collagen/hyaluronan/beta-glucan scaffold. We used direct contact assay as well as MTT test. Human adipose tissue-derived stem cells were used as biological model. According to obtained results, we can summarize, that modified collage...

The composition of the dressings is based on polyvinylpyrrolidone (PVP), polyethylene glycol (PEG), and agar. The electron beam irradiation technique has been used to prepare hydrogel wound dressings. The in vitro biocompatibility of the hydrogel was investigated by check samples (hydrocolloid Comfeel), antibacterial test (Staphylococcus aureus, Staphylococcus epidermidis, Pseudomonas aeruginos...

The aim of this study was to obtain four collagen based porous scaffolds and to assess their in vitro biocompatibility and biodegradability in order to use them for skin tissue engineering. We have prepared four variants of collagen-based biodegradable sponges by liophilization of type I collagen solution and three variants of collagen-agarose mixture in different ratios 2:1 (A), 1:1 (B) and 1:...

The natural differences between human-made electronics and biological tissues constitute a huge challenge in materials the manufacturing of next-generation bioelectronics. As such, we performed series consecutive experiments for testing biofunctionality biocompatibility device implantation, by changing exterior chemical physical properties coating it with silicone or hydrogels. In this article,...

Prior to implantation, spinal implants are subjected to rigorous testing to ensure safety and efficacy. A full battery of tests for the devices may include many steps ranging from biocompatibility tests to in vivo animal studies. This paper describes some of the essential tests from a mechanical engineering perspective (e.g., motion, load sharing, bench type tests, and finite element model anal...

aligned and random nanocomposite nanofibrous scaffolds were electrospun from polycaprolactone (pcl), poly (vinyl alcohol) (pva) and hydroxyapatite nanoparticles (nha). the morphology and mechanical characteristics of the nanofibers were evaluated using scanning electron microscopy and tensile testing, respectively. scanning electron microscopy revealed fibers with an average diameter of 123 ± 3...

Mineral trioxide aggregate (MTA) restoratives and MTA sealers are commonly used in endodontics. Commonly referenced standards for testing of MTA are ISO 6876, 9917-1 and 10993. A PubMed search was performed relating to the relevant tests within each ISO and "mineral trioxide aggregate". MTA restoratives are typically tested with a mixture of tests from multiple standards. As the setting of MTA ...
