New Nanomedicines for the topical treatment of complex wounds

Acute and chronic wounds are a growing global health problem. The incidence of non-healing chronic wounds has exponentially increased with the aging of the population and chronic diseases. It has been estimated that there is a 2% prevalence of chronic wounds in the general population, which is associated with an annual estimated cost of more than US$50 billion. Biomaterial-based treatments are helpful in improving small-sized and uncomplicated ulcers. Biologic molecules, named epidermal growth factors (EGFs) have demonstrated potent therapeutic efficacy along with limited side effects, however, exogenous EGF is rapidly cleared from the topical application site.

Jaume Veciana, Nora Ventosa and co-workers have reported a soft, reliable, and scalable method based on compressed CO2 for obtaining nanoconjugates of recombinant human epidermal growth factors and nanovesicles. These nanoconjugates exhibit appropriate physicochemical properties together with an antimicrobial activity preventing infections that promote complete closure of complex wounds. Therefore, such nanoconjugates are a potential nanomedicine for the topical treatment of complex wounds, particularly diabetic foot ulcers. The article published by the medical journal Advances in Therapy was chosen to be the cover of number 6 in June.

The use of NANBIOSIS Unit 6 of Biomaterial Processing and Nanostructuring Unit (from CIBER-BBN and ICMAB-CSIC) has allowed the obtaining of various versions of the nanoconjugates as well as their physical-chemical characteristics” – explained prof. Jaume Veciana

Purchase, installation and implementation of a treatment, distribution and management system for the environmental control and registration of animal housing rooms

There is a growing demand, coming from the scientific community, to carry out studies with animal models in the best conditions for them. For this reason, the need of implementing a new control and recording system of environmental conditions within the stabling rooms of the CCMIJU Animal Housing arises.

The whole process and the awarded company, General de Instalaciones y Conservación S.L., have been published in the following link of the Public Sector Contracting Platform, within the framework of the project “Updating of the Infrastructures and implementation of a document control and LIMS management system to enhance the capacities of the NANBIOSIS Distributed ICTS Units managed by the CCMIJU (AILIMS-NANBIOSIS)”

Link

AILIMS has been co-funded by the European Regional Development Fund (FEDER) within the framework of the Pluriregional Operational Program of Spain (POPE) of Singular Scientific and Technical Infrastructures (ICTS) 2014-2020.

The following actions are considered in the framework of the project:

-Within Unit 22 or Animal Facility, the Installation and development of an environmental treatment-control system of the housing rooms, an Improvement and adaptation of the spaces for experimental models, the Acquisition, installation and development of a two-door ultra- filtered air shower and the Acquisition, installation and development of a post-procedural recovery chamber.

– For the rest of the NANBIOSIS Units managed by the CCMIJU: Acquisition, installation and development of a LIMS Software.

The actions and their budget are detailed below, together with the FEDER co-funded rate and the national contribution.
