Biomimetic cages are obtained

Laboratory staff produced prototypes of implants designed for spinal surgery. The samples were made by 3D printing from metal powders, namely the titanium alloy Ti6Al4V, which belongs to the category of medical titanium alloys. Cages have a porous architecture for filling with osteoinductive material. Cage is used for interbody fusion (fusion of vertebral bodies) after removal of the intervertebral disc and is used in all parts of the spinal column. Titanium cages in combination with autobone can be successfully used for various types of interbody fusion along with other known implants. Thanks to the holes located in the body of the titanium cage, the bone tissue of adjacent vertebrae grows into it. Favorable conditions are created for the formation of bone-metal fusion. The use of a titanium cage reduces the invasiveness of the operation and eliminates the use of an autograft from the iliac crest.

We congratulate our friend Amanzhol Turlybekuly to be newcomer in science world!


Researcher from our workgroup has made a publication in ELSEVIER's journal

With congratulations of Amanzhol Turlybekuly, we provide abstract «Composite material with nanoscale architecture based on bioapatite, sodium alginate and ZnO microparticles» article
A nanostructured composite material in the form of a hydrogel and beads based on hydroxyapatite (HA), sodium alginate (Alg) and ZnO microparticles was fabricated under the influence of microwave irradiation. An average crystallite size of the HA was 40 nm, while ZnO crystallites of the size 25 nm–11 µm were formed. The inorganic HA-ZnO phase of studied composite is distributed in the polysaccharide matrix of the alginate, which corresponds to the structures of natural bone nanocomposites. The introduction of ZnO into the composite increases its porosity up to 5 times and the degree of swelling in phosphate buffered saline up to 2 times, as well as provides weak antimicrobial activity. The effect of microwave and ultrasonic treatment on the structure of HA-ZnO and HA-Alg-ZnO composites’ microcrystals was studied. The mechanism of antimicrobial activity of ZnO crystals in the HA-Alg-ZnO composite was proposed. The in vitro biocompatibility and cytotoxicity of the synthesized materials was studied and it was found that addition of ZnO make insignificant effect on biocompatibility. Thus, the main goal of our work was fabrication of the bioactive material using microwave and ultrasonic treatment for additional enhancement of antibacterial properties.

Production of medical implants will start in East Kazakhstan

In the east of Kazakhstan, science will help production. The leadership of the region has provided enterprises with the opportunity to take advantage of the developments of local scientists. And offered state support. Regional scientists have already applied for funding to the Ministry of Education and Science. And received prior approval. It is expected that by the end of the year they will be allocated 2 billion 700 million tenge. This money will be spent on the implementation of 10 innovative projects. They will allow modernizing technologies at industrial facilities. And they will help to master the production of modern products in demand in the world. For example, it is planned to start production of medical implants from tantalum and titanium valves for the oil and gas industry. Another important project is the development of superconductors for computer tomographs.

Zhasulan Shaimardanov, Rector of EKSTU:
- If Kazakhstan produces this product, then we can take our rightful place in the world in the production of computer tomographs. Because the main thing there is this superconducting wire. And we can produce this wire here, at the Ulba Metallurgical Plant.
