Sodium N-lauryl amino acids derived from silk protein can form catanionic aggregates with cytarabine as novel anti-tumor drug delivery systems

open access: yesDrug Delivery, 2020
A sodium N-lauryl amino acids (shortly silk sericin surfactant, SSS) is synthesized with lauryl chloride and sericin amino acids recovered from silk industrial waste. The purpose of this study is to explore whether the sericin surfactant can be used as a

Choreography of silk spinning by webspinners (Insecta: Embioptera) reflects lifestyle and hints at phylogeny [PDF]

open access: yes, 2016
Silk spinning defines the morphologically constrained embiopterans. All individuals spin for protection, including immatures, adult males and the wingless females. Enlarged front tarsi are packed with silk glands and clothed with ejectors.

Electrospun Silk Fibroin Scaffolds for Tissue Regeneration: Chemical, Structural, and Toxicological Implications of the Formic Acid-Silk Fibroin Interaction

open access: yesFrontiers in Bioengineering and Biotechnology, 2022
The dissolution of Bombyx mori silk fibroin (SF) films in formic acid (FA) for the preparation of electrospinning dopes is widely exploited to produce electrospun SF scaffolds.

Flaw-tolerance in silk fibrils explains strength, extensibility and toughness of spider silk [PDF]

open access: yes, 2011
Silk is an ancient but remarkably strong, extensible and tough material made from simple protein building blocks. Earlier work has shown that the particular molecular geometry of silk with a composite of semi-amorphous and nanocrystalline beta-sheet ...

A comparative study of mesoporous glass/silk and non-mesoporous glass/silk scaffolds: Physiochemistry and in vivo osteogenesis [PDF]

open access: yes, 2011
Mesoporous bioactive glass (MBG) is a new class of biomaterials with a well-ordered nanochannel structure, whose in vitro bioactivity is far superior than that of non-mesoporous bioactive glass (BG); the material's in vivo osteogenic properties are ...

Preparation of hexagonal GeO2 particles with particle size and crystallinity controlled by peptides, silk and silk-peptide chimeras [PDF]

open access: yes, 2014
We demonstrate the use of silk based proteins to control the particle/crystallite size during GeO2 formation, using a bio-mimetic approach at circumneutral pH and ambient temperature. Multicrystalline GeO2 was prepared from germanium tetraethoxide (TEOG)

Using T cell lymphokines of hyperimmunized chickens with Salmonella pullorum to protect layer hens against Salmonella pullorum infection [PDF]

open access: yesIraqi Journal of Veterinary Sciences, 2022
Salmonella pullorum (SP) is well adapted to cause an acute systemic infection in hens with a high mortality rate. This study aimed to assess the efficacy and safety of a salmonella-immune lymphokine (SILK) produced by hyperimmunized pullets with ...
