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
Ocular larva migrans value in diagnosing ocular toxocariasis. The retinal lesion can mimic retinoblastoma in appearance, and mistaken diagnosis of the latter condition can lead to unnecessary "enucleation". The eye involvement can cause the following inflammatory disorders: In contrast to visceral larva migrans, ocular toxocariasis usually develops in older children or young adults with no history of pica. These patients seldom have eosinophilia or visceral manifestations. Ocular larva migrans Ocular larva migrans (OLM), also known as ocular toxocariasis, is the ocular form of the larva migrans syndrome that occurs when "Toxocara canis" (dog roundworm) larvae invade the eye. They may be associated with
