Silk gut processed from the silk glands of the silkworm could be an ideal biodegradable carrier for cell growth factors. We previously demonstrated that polyhedra, microcrystals of Cypovirus 1 polyhedrin, can serve as versatile carrier proteins. Here, we report the generation of a transgenic silkworm that expresses polyhedrin together with human basic fibroblast growth factor (FGF-2) in its pos...

The study aimed to evaluate the beneficial effect of platelets rich plasma (PRP) on wound heal in rabbit.Eighteen healthy male adult rabbit were used they randomly divided into two equal groups (controlgroup 9, treated group 9). Under aseptic technique 3 cm skin incision was made back (dorsal) ofanimal by scalpel, after that sutured immediately silk suture materials 0.2 USP usedsimple interrupt...

Nature has evolved a range of materials that compete with man-made materials in physical properties; one of these is spider silk. Silk is a fibrous material that exhibits extremely high strength and toughness with regard to its low density. In this review we discuss the molecular structure of spider silk and how this understanding has allowed the development of recombinant silk proteins that mi...

Understanding the compatibility between spider silk and conducting materials is essential to advance the use of spider silk in electronic applications. Spider silk is tough, but becomes soft when exposed to water. Here we report a strong affinity of amine-functionalised multi-walled carbon nanotubes for spider silk, with coating assisted by a water and mechanical shear method. The nanotubes adh...

Spider silk has been studied recently because of its tremendous strength and flexibility [1]. Biotechnology now opens possibilities for the application of spider silk [2–7]. We describe a new avenue for the application of spider silk in textile science and industry. Recently, spider silk/carbon nanotube composites have been prepared, and their mechanical and electrical properties characterized....

Neutron reflectivity (NR) measurements of ultrathin surface films (below 30 nm) composed of Bombyx mori silk fibroin protein in combination with atomic force microscopy and ellipsometry were used to reveal the internal structural organization in both dry and swollen states. Reconstituted aqueous silk solution deposited on a silicon substrate using the spin-assisted layer-by-layer (SA-LbL) tec...

A combination of solid state 1H NMR chemical shift measurements and empirical chemical shift calculations has been used to interpret 1H solid state chemical shifts of a model peptide (Ala-Gly)15 for the crystalline domain of Bombyx mori silk fibroin in silk I and silk II structures, including a treatment of both intra- and intermolecular arrangements. Silk I and silk II are the structures of si...

After the repair of rupture or avulsion of the triceps tendon it is usual to immobilise the elbow in plaster for a few weeks. A method is described which obviates the need for plaster and permits early mobilisation of the elbow. Technique. The patient lies in the prone position with the injured arm resting on his chest and supported by an assistant. A straight posterior incision is made from ab...

Silk fibroin from the silkworm, Bombyx mori, has excellent properties such as biocompatibility, biodegradation, non-toxicity, adsorption properties, etc. As a kind of ideal biomaterial, silk fibroin has been widely used since it was first utilized for sutures a long time ago. The degradation behavior of silk biomaterials is obviously important for medical applications. This article will focus o...

BACKGROUND Several materials have been used for tissue engineering purposes, since the ideal matrix depends on the desired tissue. Silk biomaterials have come to focus due to their great mechanical properties. As untreated silkworm silk has been found to be quite immunogenic, an alternative could be spider silk. Not only does it own unique mechanical properties, its biocompatibility has been sh...
