Judit Tomsen: Best oral presentation at ESC 2019


Last June 18-22 at the 2019, ESC meeting, the European Students Colloid Conference, that took place in Varna, Bulgaria, Judit Tomsen,  PhD fellow at the Nanomol group from CIBER-BBN and ICMAB-CSIC, was awarded with the best oral presentation.

Judit Tomsen, who carries out her work under supervision of Nora Ventosa,  Scientific Director of NANBIOSIS U6 Biomaterial Processing and Nanostructuring Unit, presented her oral communication entitled “Design of peptide targeted nanovesicles for the α-galactosidase A enzyme delivery“. Her talk explained some of the smart4fabry european project results, a project coordinated by CIBER-BBN and Nora Ventosa in which participates NANBIOSIS Unit 6.

The European Colloids and Interfaces Society (ECIS) organizes biannually ESC meetings of advanced students at PhD and MSc level who are undertaking research in the area of colloid and interface science at a European University.

NANBIOSIS U20 at the Nanomed Europe Conference, NME19.

Last week took place in Braga, Portugal, the Nanomed Europe Conference, NME19, a new and unique conference  born from the merge of the 14th annual event of the ETPN & the European scientific conference ENM (after London 2017 & Grenoble 2015), bringing together scientists, technology providers, entrepreneurs, industry and clinicians, all of them developing great medical applications of Nanotechnologies and emerging MedTech. The event is been co-organized this year by the ETPN and INL.

Simó Schwartz, Scientific Director of NANBIOSIS U20, was one of the selected speakers and gave a lecture about “Preclinical development of magnetic nanoparticles for the treatment of pancreatic cancer”

Two posters mentioning the research carried out at NANBIOSIS Unit 20 were also presented. (See the picture)

It was also a ood opportunity to explain the advances in the two H2020 projects where NANBIOSIS U20 participates (“Nocanther” and “Smart4Fabry”), and also an internal project, “Meridian”, on the use of exosomes (with own patent and financed by the FIS).

In Nocanther Project, the U20 participates providing the animal models and the imaging techniques (X-ray CT images) for the biodistribution and efficacy assays of iron oxide nanoparticles. These assays are essential for preparing the dossier for the clinical application of these nanoparticles. Indeed, patient recruitment for clinical studies on Nocanther project will start in 2020.

In Smart4Fabry, the U20 works completing the efficacy assays of different nanoGLA formulations. Again, these efficacy assays will be a necessary step before starting preclinical regulatory assays.

In the MERIAN project, U20 provides the in vivo proof-of-concept and biodistribution assays that support the use of protein loaded exosomes as a feasible product for treating lysosomal storage disorders.

Laparoscopic surgery in the uterus retrieval procedure during uterine transplantation

Researchers of NANBIOSIS units at JUMISC have recently published the results of an study that highlights the promising application of laparoscopy for graft procurement surgery in uterine transplantation from living donors for absolute uterine infertility treatment. Laparoscopy seems to be a safe, time saving, useful and technically feasible surgical procedure for uterus extraction, with the additional benefits of minimally invasive surgery. It was also demonstrated that after a successful uterine transplant, pregnancy can be achieved by combining laparoscopy for uterine retrieval and microsurgery for vascular anastomosis. With the increasing success rate of human uterus transplantation trials from living donors, it is very probable that laparoscopic graft extraction will soon become a reality in the transplantation field. However, uterus transplantation will remain as a clinical experimental procedure until sufficient experience is achieved.

The resarch has been executed by using the Unique Scientific and Technical Infrastructure (ICTS) “NANBIOSIS.”

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.
