We report a strategy for preserving the structural features of collagen triple helix in turbostratic graphite.
Abstract Purpose The aging of zirconia ceramics (Y‐TZP) is associated with tetragonal to monoclinic phase transformation. This change in microstructure may affect the optical properties ceramic. study examines effect on translucency different materials. Materials and Methods 120 disc‐shaped specimens were fabricated from four materials: Cercon ht white, BruxZir Solid Zirconia, Zenostar T0, Lava Plus (n = 30 per group). Accelerated was performed a steam autoclave (134°C, 0.2 MPa, 5 hours)....
The bioactive bromotyrosine-derived alkaloids and unique morphologically-defined fibrous skeleton of chitin origin have been found recently in marine demosponges the order Verongiida. sophisticated three-dimensional (3D) structure skeletal chitinous scaffolds supported their use biomedicine, tissue engineering as well diverse modern technologies. goal this study was screening new species Verongiida to find another renewable source naturally prefabricated 3D scaffolds. Special attention paid...
Marine demosponges (Porifera: Demospongiae) are recognized as first metazoans which have developed over millions of years evolution effective survival strategies based on unique metabolic pathways to produce both biologically active secondary metabolites and biopolymer-based stiff skeletons with 3D architecture. Up date, among marine demosponges, only representatives the Verongiida order been known synthetize substances well made structural polysaccharide chitin. This work, our knowledge,...
Abstract Natural structural biomaterials of marine origin including mollusc shells, sponges and corals not only provide an abundant source novel bone cartilage replacements but also inspire investigations to develop nano‐sized biomimetic composites. This study presents a characterisation the ultrastructure deep‐sea Bamboo coral (Anthozoa: Gorgonacea: Isididae) nanostructure some interstitial surfaces with respect biomineralization phenomena. The skeletons examined exhibit jointed axes large...
Sponges (Porifera) are recognized as aquatic multicellular organisms which developed an effective biochemical pathway over millions of years evolution to produce both biologically active secondary metabolites and biopolymer-based skeletal structures. Among marine demosponges, only representatives the Verongiida order known synthetize substances well skeletons made structural polysaccharide chitin. The unique three-dimensional (3D) architecture such chitinous opens widow for their recent...
ABSTRACT Demosponges (phylum Porifera) are among the first multicellular organisms on planet and represent a unique archive of biosilica‐based skeletal structures with species‐specific microstructures called spicules. With more than 80 morphotypes, this class sponges is recognized as source amorphous silica superficial ornamentation patterned by organic phases. In study, we investigated spicules selected representatives family Geodiidae (order Tetractinellida), to identify F‐actin‐containing...
<b><i>Background: </i></b>The study describes the development and implementation of a digital nose database in order to provide patients with nasal prostheses following rhinectomy. Mirrored data for computer-aided design (CAD) cannot be used due unpaired structure nose. <b><i>Materials Methods: faces 202 people were digitized using 3-dimension (3D) scanner. The noses scaled, measured classified according objective criteria. physician, patient...
Three dimensional (3D) printing allows additive manufacturing of patient specific scaffolds with varying pore size and geometry. Such porous scaffolds, made 3D-printable bone-like calcium phosphate cement (CPC), are suitable for bone augmentation due to their benefit osteogenesis. Their pores allow blood-, bone- stem cells migrate, colonize finally integrate into the adjacent tissue. Furthermore, affects scaffold’s stability. Since in maxillofacial surgery have withstand high forces within...
Three-dimensional chitinous scaffolds often used in regenerative medicine, tissue engineering, biomimetics and technology are mostly isolated from marine organisms, such as sponges (Porifera). In this work, we report the results of electrochemical isolation ready to use matrices three species verongiid demosponges (Aplysina archeri, Ianthella basta Suberea clavata) a perfect example possible morphological chemical dimorphism case chitin sources. The electrolysis concentrated Na2SO4 aqueous...
Aminopolysaccharide chitin is one of the main structural biopolymers in sponges that responsible for mechanical stability their unique 3D-structured microfibrous and porous skeletons. Chitin representatives exclusively marine Verongiida demosponges exists form biocomposite-based scaffolds chemically bounded with biominerals, lipids, proteins, bromotyrosines. Treatment alkalis remains classical approaches to isolate pure from sponge skeleton. For first time, we carried out extraction...
