Development of a new injectable biomaterial for the treatment of bone diseases such as osteoporosis

11.10.2007
Researchers of the BIOMAT (Biomaterials Centre) of the Universidad de La Habana have obtained an injectable macro-porous material, useful for the treatment of degenerative diseases such as osteoporosis, to refill bone cavities and in stomatology.

According to Amisel Almirall, researcher of the BIOMAT and in charge of this project, “one of the main difficulties of medicine at present is the considerable increase of the pathologies related to bone problems. Half the chronic diseases suffered by people over 65 are related to articulation deficiencies; in addition, the number of bone fractures caused by osteoporosis and traffic accidents has doubled in the last ten years”.

The macro-porous calcium phosphate cement developed in this research centre, enriched with tricalcium phosphate and porogenic agents such as serum albumin, has high probabilities of improving the quality of life of patients with bone fragility, preventing them from breaking and allowing a better mobility.

Bone reconstitution

Almirall confirmed the docility of this compound and its capacity to be implanted in bones as an injectable filling in cases of gum cyst removal, preventing teeth weakening thanks to the fast reconstitution of the bone. According to her, the search for new materials to substitute different parts of the human body comes from the need of offering a batter quality of life to those persons who suffer chronic diseases without medical solution.

The injectable compound, obtained thanks to the collaboration between of Maria-Pau Ginebra, researcher from the División de Biomateriales (Biomaterials Division) of the Universidad Politécnica de Cataluña (Technical University of Catalonia), is very similar to bone mineral composition and, as a result, it is very useful for tissue engineering, this is, for "sowing” cells of the patient in the material to implant it later.

The compound, which is still in research and with results published in the journals Revista Iberoamericana de Polímeros and Magazine Interscience, is easy to manipulate, of fast compression and has flexible properties similar to the reports of macro-porous materials in international scientific literature. If they were registered, it would be possible to substitute other similar materials such as Biobone, Norian SRS, Norian-CRS and Bonesource, produced in the First World and very expensive in the international market.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
