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...

an experiment was conducted to study the effect on performance of silkworm bombyx mori l., when fed by leaves of different mulberry varieties a crd design with 12 tratments (including kamasari, kaeiryo ichinose, kaeerizhotezomigaeeshi, tachibana, ichinose, chekemaoha, yukishinogi, shin ichinose, wasemidori, roso, kenmochi, as well as some local varieties in 4 replications. the larvae were reare...

Fully fed larvae of three Australian bee species formerly classified as Colletidae: Paracolletini are described and compared in light recent phylogenetic studies. Two these species, Leioproctus (Goniocolletes) wanni (Leijs Hogendoorn) Trichocolletes orientalis Batley Houston, belong the Neopasiphaeinae, while third, Paracolletes crassipes Smith, belongs Diphaglossinae: (sensu Almeida et al., 20...

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...
