Tissue equivalent tubular scaffold structure, and methods of production thereof

The present invention provides tissue equivalent scaffold structures and methods of production thereof. Such methods include providing a casting chamber comprising an elongate mould portion, axially disposing a lumen template within the elongate mould portion, and at least partly filling the casting chamber with a gel casting material comprising a matrix of fibrils or fibres and an interstitial fluid phase, such that a portion of the lumen template extends above the casting material. The fluid phase of the gel is allow to flow axially out of the elongate mould portion, in a restricted manner, thereby resulting in axial densification of the gel casting material to form a tissue equivalent tubular scaffold. Tissue equivalent scaffold structures according to the present invention are able to support cell populations both within the walls and on the surface of the construct. They have enhanced mechanical strength due to increased collagen density, and are customisable in terms of luminal diameter and wall thickness. They may find application in tubular tissue engineering.

Methods and compositions for synthesizing improved silk fibers

Method and machine for the production of portions, including means for ejecting said portions

The invention relates to a method and a device for the production of portions from at least one continuous strand of a food product, in particular for the production of meatballs. The machine comprises: an extrusion device which can deliver a continuous strand in a vertical direction, and a portioning device that includes at least one cutting system. The cutting system comprises cutting elements (30) which can be moved transversely to the vertical direction between an open position, in which the strand passes between the cutting elements, and a closed position for cutting the strand and forming portions of the food product. In addition, each cutting system comprises ejection means (5) for ejecting the forming portions downwards from the cutting elements. The ejection means include at least one lower channel (5, 105) that is fluidly connected to a compressed fluid such that compressed fluid can be injected into the lower channel when the lower channel is in a closed position. The lower channel is formed in a body of the corresponding cutting element.

Method Of Manufacturing Embedded Water Soluble Film Carrier

A water-soluble film (WSF) system comprises at least one active material embedded/entrapped in the film so as to provide precise and desired release of the at least one active material therefrom. The at least one active material includes detergents, enzymes, softeners, perfumes, pesticides, fungicides, active ingredients, dyes, pigments, hazardous chemicals, active agents for cleaning laundry, dishes, floorings, walls, furniture, fluffs, pulp, and combinations thereof. Online and offline processes can be used for the manufacture of multi-layered WSFs with or without liners. The WSFs can be formed in desired shapes to selectively entrap interacting/non-interacting materials and combinations thereof. The process also provides options for the use of a wide range of raw materials, liners such as paper, film, foil, fabric, etc.
