The abdominal cocoon is a rare cause of intestinal obstruction that is usually diagnosed at the time of laparotomy. It is usually of unknown origin, although at times, it may be seen secondary to a variety of conditions. Tuberculosis is an infrequently implicated cause of abdominal cocoon, and has only occasionally been reported previously in the Literature. This paper presents our experience w...

Bombyx mori cocoon is a natural composite made of silk fibre with a distinctive multi-layer structure that provides mechanical protection for its biological functions. Here we investigate the components, structure and mechanical properties of cocoon layers, and quantify the contributions of the multi-layer structure to the mechanical properties of cocoon. A better understanding of the multi-lay...

Abstract Most ant species have lost the ability to spin cocoons. To explore evolution of cocoon loss within Formicidae, we perform an ancestral state reconstruction cocooned pupae across a genus-level phylogeny and use sister clade analysis determine impact on speciation. Then, fit models correlated between status several other organismal traits. We find that re-emergence cocoons is rare “naked...

Agriculture plays a key role in the economy of Uzbekistan. Its importance is not limited to goals providing food population. This reflected cultural heritage and traditions people Uzbekistan rural areas, each region with its own characteristics diversity. Today, agriculture general, including cocooning, provides jobs income significant part population remains driving force growth At same time, ...

Bombyx mori cocoon has a multi-layer structure that provides optimal protection for silkworm pupa. Research on the mechanical properties of the multi-layer structure revealed structure-property relationships of the cocoon. Here, we investigated the protein components of the B. mori cocoon in terms of its multi-layer structure. Liquid chromatography-tandem mass spectrometry identified 286 protei...

Antherina suraka Boisduval (Saturniidae, Lepidoptera) produces a silken cocoon that has been the focus of efforts to create a commercial wild silk industry in Madagascar. In this study, structural and mechanical properties of the cocoon of A. suraka from two sites were measured and compared to the cocoon of Bombyx mori L. (Bombycidae, Lepidoptera) the world's most common source for silk. Result...

Objectives. The aim of this paper was to evaluate the cytotoxicity of Indonesian silkworm cocoon extract of Cricula triphenestrata on human fibroblasts. Methods and Materials. The cocoon shells of the silkworm Cricula triphenestrata were degumming. The shells were mixed with an aqueous solution of 0.3% Na(2)CO(3) at 98°C for 1 hour. The solution was then dialyzed in cellulose membranes against ...

AIM Abdominal cocoon is a rare cause of intestinal obstruction usually diagnosed incidentally at laparotomy. It manifests by forming a membrane that typically encases the small bowel loops, leading to mechanical obstruction. Preoperative diagnosis is difficult. The etiology of this condition is not well understood; however, it is a form of chronic irritation and inflammation. METHOD A 33 year...

Bombyx mori nucleopolyhedrovirus (BmNPV) that infects the silkworm, B. mori, accounts for >50% of silk cocoon crop losses globally. We speculated that simultaneous targeting of several BmNPV essential genes in transgenic silkworm would elicit a stable defense against the virus. We introduced into the silkworm germline the vectors carrying short sequences of four essential BmNPV genes in tandem,...
