Polish scientists use bacterial cellulose to develop tracheal prostheses
Bacterial cellulose is a porous mesh nano-scale biopolymer material synthesized by microorganisms. It has high water retention, high gas permeability, good biocompatibility, high mechanical strength, three-dimensional network structure and other unique properties. Will not be rejected, widely used in regenerative medicine. Most of the currently available tracheal prostheses are made of plastic, and their biocompatibility is poor. Due to the lack of a porous structure, they cannot be penetrated by cells or blood vessels and are not easily accepted by the patient. The tracheal prosthesis made of bacterial cellulose, due to its unique nanostructure, can be covered by airway epithelial cells or capillaries, and can be stored in the patient's body after implantation. Researchers have developed tracheal prosthesis structures, and tolerance tests have shown that they have properties similar to natural gas tubes. Currently, they are testing the ability of naturally occurring epithelial cells in the trachea to grow on the prosthesis. Ideally, the prosthesis should be combined with the epithelial cells inside the trachea and exert the natural function of the trachea, including introducing air into the lungs through the nose and throat, and filtering impurities trapped in the upper respiratory tract. The team has made many achievements in the field of bacterial cellulose. They interpret the genome of bacterial strains that produce this biomaterial and commercialize bacterial cellulose production technology. Products developed include biocompatible meshes for the treatment of hernias, as well as bacterial cellulose dressings for the treatment of wounds that are difficult to heal. (Technology Department) Automatic Massage Foot Bath Machine The automatic massage foot bath machine is a device that uses water and massage rollers to provide a relaxing foot massage. It usually has a basin filled with water and has built-in massage rollers that move and massage the feet. The machine may also have other functions, such as heat therapy, air bubbles, and vibration. Users place their feet in the basin and the machine provides a soothing massage that helps relieve tension and improve foot circulation. Some automatic foot massage machines also come with removable attachments for additional massage options.
