Silk remarkable mechanical properties, comparative biocompatibility, tunable degradation rates "in vitro" and "in vivo", the ease to load cellular growth factors (for example, BMP-2), and the ability to be processed into several other formats such as films, gels, particles, and scaffolds. Silks from "Bombyx mori", a kind of cultivated silkworm, are the most widely investigated silks. Silks derived from "Bombyx mori" are generally made of two parts: the silk fibroin fiber which contains a light chain of 25kDa and a heavy chain of 350kDa (or 390kDa) linked by a single disulfide bond and a glue-like protein, sericin, comprising 25 to 30
Visceral larva migrans Visceral larva migrans Visceral larva migrans (VLM) is a condition in humans caused by the migratory larvae of certain nematodes, humans being a dead-end host, and was first reported in 1952. Nematodes causing such zoonotic infections are "Baylisascaris procyonis", "Toxocara canis", "Toxocara cati", and "Ascaris suum". These nematodes can infect but not mature in humans and after migrating through the intestinal wall, travel with the blood stream to various organs where they cause inflammation and damage. Affected organs can include the liver, heart (causing myocarditis) and the CNS (causing dysfunction, seizures, and coma). A special variant is ocular larva migrans
