Cocoon silks are composed of two silk proteins: sericin and fibroin. Fibroin is a semi crystalline polymer of natural fibrous protein mainly consisting of highly β-sheet crystals and noncrystalline part (micro voids and amorphous structures). Sericin is amorphous acting as an adhesive binder to maintain the fine filaments of fibroin core and the overall structural integrity of cocoon [1]. Silk ...

We examine the impact of cross-prefectural differences in financial integration on the regional spread of Japan’s Great Recession in the early 1990s. In prefectures with many small manufacturing firms, post-1990 growth was significantly lower if low levels of banking integration with the rest of the country before 1990 existed. The least financially integrated and most credit-dependent prefectu...

The silk industry was historically the most important industrial sector from Trás-os-Montes, with no competition until the 19 century. For centuries, it was the economic activity most open to the outside and the first to yield to the new capitalist mentality. It was, undoubtedly, the productive activity that contributed most to the national and international acknowledgment of the region and its...

The biocompatibility and biodegradability of natural silk fibres and the benign conditions under which they (with impressive mechanical properties) are produced represent a biomimetic ideal. This ideal has inspired people in both academia and industry to prepare silk-mimetic polymers and proteins by chemical and/or biotechnological means. In the present paper, we aim to give an overview of the ...

The mango leaf webber, Orthaga exvinacea makes silken webs and galleries during its larval stage. Silk is produced from the silk gland of this insect. Quantitative and qualitative analysis of proteins from the silk glands of last three larval stages and pre-pupae were conducted. Significant differences were observed among different stages. SDS-PAGE of proteins from anterior, middle and posterio...
