In this study, the achene mucilage content of six Turkish endemic Tripleurospermum taxa, namely T. baytopianum E. Hossain, conoclinium (Boiss. & Bal.) Hayek, fissurale (Sosn.) hygrophilum (Bornm.) Bornm., rosellum Orph.) Hayek var. album Hossain and ziganaense Inceer Hayirlioglu-Ayaz was determined by micro-staining reactions. Within examined cells on surface are capable forming a musil...

Development of the technique for constructing an internal perfusable vascular network is a challenging issue in fabrication of dense three-dimensional tissues in vitro. Here, we report a method for realizing it. We assembled small tissue (about 200 μm in diameter)-enclosing hydrogel microcapsules and a single hydrogel fiber, both covered with human vascular endothelial cells in a collagen gel. ...

Various culture conditions, such as the presence of ascorbic acid, initial plating density and the nature of the substratum (plastic, gelatin or native collagen gels), influenced the growth, morphology and migration of three cloned populations of adult bovine aorta endothelial cells. Aorta endothelial cells showed two distinctive and reversible morphological phenotypes. Cells presenting a free ...

The attachment of Pseudomonas aeruginosa to human respiratory mucus represents an important step in the development of lung infection, especially in cases of cystic fibrosis. For this purpose, microtiter plate adhesion assays have been developed and have suggested that nonpilus adhesins of P. aeruginosa are the most important ones for binding to human respiratory mucins. In order to characteriz...

We propose an e-textile bioelectrode array that consists of screen-printed silver paste wiring, a thermoplastic polyurethane insulation layer, and ionic liquid gel-embedded knit textile pads for wearable whole-body medical healthcare monitoring. The technical challenges in integrating bioelectrodes onto include forming layer on wiring fixing gel the since is removed by organic solvent conventio...

We have fabricated a hepatic tissue construct using a multilayer photopatterning platform for embedding cells in hydrogels of complex architecture. We first explored the potential of established hepatocyte culture models to stabilize isolated hepatocytes for photoencapsulation (e.g., double gel, Matrigel, cocultivation with nonparenchymal cells). Using photopolymerizable PEG hydrogels, we then ...

background: bleaching the discoloured teeth may affect the tooth/composite interface. the aim of this in vitro experimental study was to evaluate the effect of vital tooth bleaching on microleakage of existent class v composite resin restorations bonded with three dental bonding agents.     methods: class v cavities were prepared on buccal surfaces of 72 intact, extracted human anterior teeth w...

The sea cucumber Holothuria forskåli possesses a specialized system called Cuvierian tubules. During mechanical stimulation white filaments (tubules) are expelled and become sticky upon contact with any object. We isolated a protein with adhesive properties from protein extracts of Cuvierian tubules from H. forskåli. This protein was identified by antibodies against recombinant precollagen D wh...

The objective of this study was to evaluate the use of a two-step total etch and rinse adhesive, the correlation between the hyybrid layer thickness (HL) and bond strength (BS), and between resin tag length (RT) and bond strength in the same teeth, and also to evaluate the fracture patterns of the tested specimens. Ten human molars were used for the restorative procedure and then sectioned in t...

UNLABELLED Dentin adhesion procedure presents limitations, especially regarding to lifetime stability of formed hybrid layer. Alternative procedures have been studied in order to improve adhesion to dentin. OBJECTIVE The aim of this study was to evaluate in vitro the influence of deproteinization or dentin tubular occlusion, as well as the combination of both techniques, on microtensile bond ...
