“…Silk fibroin was extracted from the natural silkworm cocoon (Zhejiang Province, China) using a method reported previously [14]. The cocoons were heated to boil for 1 h in an aqueous Na 2 CO 3 solution (0.5 wt%) and rinsed with water to remove the sericin.…”

In the field of tissue engineering, polymeric materials with high biocompatibility like polylactic acid and polyglycolic acid have been widely used for fabricating living constructs. For hypopharynx tissue engineering, skeletal muscle is one important functional part of the whole organ, which assembles the unidirectionally aligned myotubes. In this study, a polyurethane (PU) scaffold with microchannel patterns was used to provide aligning guidance for the seeded human myoblasts. Due to the low hydrophilicity of PU, the scaffold was grafted with silk fibroin (PU-SF) or gelatin (PU-Gel) to improve its cell adhesion properties. Scaffolds were observed to degrade slowly over time, and their mechanical properties and hydrophilicities were improved through the surface grafting. Also, the myoblasts seeded on PU-SF had the higher proliferative rate and better differentiation compared with those on the control or PU-Gel. Our results demonstrate that polyurethane scaffolds seeded with myoblasts hold promise to guide hypopharynx muscle regeneration.

“…The dye uptake of silk fiber degummed with citric acid showed 4.2% reduction compared to the dye uptake of silk degummed with soapalkali method. The higher dye uptake in the case of soap-alkali degummed silk is due to the disordering of the molecular orientation of silk fibroin accompanied with its partial hydrolysis (Khan et al, 2010).…”

“…Se han estudiado métodos de desengomado con agua caliente [21], con la asistencia de autoclaves o de microondas [22]. También se encuentran reportes de procesos de desemgonado con enzimas tipo proteasas [23,24] y basados en medios ácidos [25,26]. En los proceso de desengomado de la seda, las variables a tener en cuenta son: la concentración del jabón, el ácido, el álcali o la enzima que se emplea; la temperatura, el tiempo y el pH del baño [27,28].…”

RESUMENLa seda es un filamento de origen animal producido por el gusano Bombyx mori. Esta fibra se caracteriza por su suavidad y brillo único, lo cual se atribuye a la forma triangular de su sección transversal. Además, tiene una alta resistencia a la tracción y una alta tenacidad, similar a la de algunas fibras sintéticas. En este trabajo se realizó una revisión bibliográfica de los procesos que requiere la seda para obtener un teñido homogéneo, partiendo desde los tratamientos previos de tintura hasta las pruebas de caracterización de solidez del color.Palabras clave: Seda, Gusano Bombyx mori, Teñido, Colorantes, GOTS. ABSTRACTSilk is a filament of animal origin produced by the Bombyx mori silkworm. This fiber is characterized by its unique softness and gloss, which is attributed to the triangular shape of its cross section. It also has a high tensile strength and a high toughness, similar to some synthetic fibers. In this paper an literature review of the processes required for a homogeneous dyeing in silk was performed, starting from the dyeing pretreatments up to the color fastness characterization tests.
