New Antimicrobial surfaces with self-cleaning properties and NANBIOSIS Unit 17

In the last decades, increased resistance to conventional antibiotics has led to important research in the development of alternative strategies for preventing pathogen dissemination. Antimicrobial surfaces containing a biocidal agent inhibit or reduce microorganisms growth capacity on the surface of materials. In addition to this microbial proliferation inhibition, antimicrobial coatings may also confer additional properties.

Researchers from the University of Alcalá and the CSIC Institute of Catalysis and Petrochemistry, have carried out a research about the self-cleaning properties of antimicrobial surfaces functionalized by photocatalytic ZnO electrosprayed coatings.

The authors prepared electrosprayed photoactive coatings of sol-gel ZnO nanoparticles tested as dual action self-cleaning antimicrobial surfaces. The materials showed excellent photocatalytic and photodisinfection properties due to the release of bioavailable zinc and photogenerated oxidative species. The surfaces were free from bacterial colonization and biofilm formation.

Confocal microscopy of NANBIOSIS U17 was used to reveal biofilm matrix using FilmTracer SYPRO Ruby stain and to assess cell viability by means of Live/Dead BacLight Bacterial Viability Kit.

NANBIOSIS Scientific Women in the International Day of Women and Girls in Science

Today February 11 is the International Day of Women and Girls in Science, a day to raise awareness of the gender gap in science and technology.

According to the United Nations, while yet women and girls continue to be excluded from participating fully in science, science and gender equality are vital to achieve the internationally agreed development goals, including the 2030 Agenda for Sustainable Development. Thus, in recent years, the international community has made a great effort to inspire and promote the participation of women and girls in science.

NANBIOSIS wants to acknowledge  the efforts made by scientific women who struggle every day to contribute their bit to Science and highlight their essential role in nowadays research.

New Zealand White rabbit as a model for preclinical studies addressing tissue repair at the level of the abdominal wall.

Juan Manuel Bellón and Gemma Pascual, Scientific Director and Coordinator of Unit 17 of NANBIOSIS, have recently published an article in the prestigious journal Tissue Eng Part C Methods.

Once a prosthetic material is implanted, an inflammatory reaction is induced in an attempt to remove it or isolate it from the host tissue. After this initial response, a cellular response takes place that gives rise to the start of the process of integration of the biomaterial within the host tissue. Immunohistochemical studies can provide information on the events that regulate this process, and are useful to analyze the progression of the implant and the neoformed tissue. For the tissue repair of a damaged area constantly subjected to tensile forces such as the abdominal wall, optimal collagenization is an extremely important factor. The proper deposition and organization of mainly collagen type I in the neoformed scar tissue will condition the mechanical strength and compliance of the repair zone and thus possible hernia recurrence. In this report, we review the use of the New Zealand White rabbit as the experimental animal for several models of abdominal wall repair and among other techniques, collagen component of the implants was assessed by immunofluorescence using anti-collagen type I and type III monoclonal antibodies. Samples were examined using a confocal microscope Leica SP5 belonging to the platform ICTS ‘NANBIOSIS’ U17 of the CIBER-BBN at the University of Alcalá.

Important information gained from selected models was observed in terms of tissue ingrowth and collagen deposition in the implant area showing significant differences depending on the properties of the implanted prosthetic material. Some variations were also observed in biomechanical properties according to the components comprising each prosthetic material.

Best Abstract award at the European Society for Surgical Research meeting

Verónica Gómez-Gil, collaborator in Unit 17 of NANBIOSIS and the GITBIT-UAH group (CIBER-BBN), has been the first prizewinner in the Best Abstract Competition  at the symposium “New horizons in prevention and treatment of adhesions” organized by the Dutch Adhesion Group (DAG) at the 52nd meeting of the European Society for Surgical Reseach (ESSR). The ESSR 2017 meeting was held in Amsterdam from 14th till 17th June. The title of the abstract, presented as a quick-shot presentation and a full oral during the congress, was: An experimental adhesiogenic model to evaluate histological events over time in the omentum during adhesion formation.

This work shows that distribution of soluble and membrane-bound form of betaglycan, together with the expression of TGF-β1 and TGF-β3 at each time point after adhesion formation, are key factors to the cytoarchitecture and composition of omental adhesion tissue. These findings are of interest in the design of new adhesion prevention strategies.
