Infections such as Candiasis will be detected in 30 minutes

Ramón Martínez Máñez, Elena Aznar and Ángela Ribes, researchers of Unit 26 of NANBIOSIS, NMR: Biomedical Applications II, in collaboration with researchers from the Universitat Politècnica de València, with the Universitari i Politècnic La Fe Hospital and the Rovira i Virgili University, have developed a new material that allows to detect quickly and with a high sensitivity infections caused by Candida albicans, a type of fungus that can be found in different biological fluids, causing opportunistic infections such as Candidemia or Invasive Candidiasis.

According to Javier Pemán, head of section and head of the Mycology Unit of the Microbiology Service of the Hospital Universitari i Politècnic La Fe,” infections are difficult to identify early, very frequent in most Intensive Care Units (ICUs) and represent an important challenge in critical patients”.

Currently, these infections are diagnosed by culturing the biological fluid to be studied and subsequent identification of yeast isolated by different microbiological techniques whose results can take between 3 and 4 days. Meanwhile, with this new material and method – patented by the UPV, the CIBER, the Hospital La Fe and the URV – the diagnostic time is reduced to only 30 minutes.

“The tests can be carried out quickly and practically in the same consultation in which the patient sample is taken, significantly reducing the equipment necessary to detect the presence of Candida albicans. Our work facilitates the diagnosis and medical decision-making, through the use of a powerful and fast tool to detect the infection”, says Ramón Martínez Máñez, scientific director of the CIBER-BBN and director of the IDM Institute at the UPV, as well as scientific director of NANBIOSIS U26.

Nanoporous films with molecular doors

The material developed by the CIBER-BBN research gourp, led by Ramón Martínez Máñez, is about nanoporous alumina films that incorporate “molecular doors” based on oligonucleotides. The characterization has been carried out in Unit 26 of NANBIOSIS, NMR: Biomedical Applications II.

“They are constituted by a porous inorganic support that is loaded with a dye and by simple strands of DNA. These strands are anchored to the surface of the support and act as “molecular doors” that inhibit the release of the indicator “, explains Ramón Martínez Máñez.

In addition, according to Professor Lluis Marsal, from the Rovira i Virgili University, the type of support used greatly simplifies the methodology of the experiment.

On how to detect the infection, Professor Martínez Máñez explains that the simple strands of DNA are selected taking into account a specific sequence of Candida albicans.

“When the presence of the DNA of this fungus is noticed, it interacts with the molecular door, the pores open and that is when the release of the dye that is inside the nanoporous support takes place, thus detecting the infection,” adds Elena Aznar , researcher of the CIBER-BBN in the IDM-UPV.

The diagnostic material is now in the clinical validation phase, thanks to the funding obtained through the CANDI-GATE project granted by the Polytechnic University of Valencia and the La Fe Health Research Institute and led by M. Angeles Tormo and Elena Aznar and through the CANDI-EYE valuation project granted by the CIBER-BBN and led by Elena Aznar.

Why research in micro-electronics? Neural interfaces, interaction between the nervous and the artificial system

Dra. Rosa Villa,  Scientific Director of NANBIOSIS U8. Micro – Nano Technology Unit, explained last June, 11 at the Residence of Researchers of Barcelona the great scientific challenges in finding tools that allow a good interaction between the nervous and the artificial system.

This talk is part of the series of conferences organized by the CNM with the theme “Why research in micro-electronics?” Dr. Manuel Lozano, Director of the CNM, introduced the talk explaining that with microelectronic technology scientists  can capture the signals that occur in the nerves and in the brain and presented Rosa Villa  as a doctor  with a PhD in cochlear implants (electronic medical devices that perform the work of damaged parts of the inner ear (cochlea) to provide sound signals to the brain). Dr. Villa now directs the group of biomedical applications of the CNM that currently uses nano technologies in their research. Her training in medicine and microelectronics has allowed her to tackle electronic-based projects with biomedical application. Her lines of research are focused, nowadays, on neural interfaces and on organ-on-chip technology, (a multi-channel 3-D microfluidic cell culture chip that simulates the activities, mechanics and physiological response of the entire organs and organ systems, the group of Dr. Villa works mainly the liver, very useful for the test of drug patho-toxicity).

In this talk, Rosa Villa explains her second line research of neural interfaces, the development of suitable interfaces between the biological systems and electronic devices and how they study the improvement of the necessary technologies to restore the motor skills or to know how the brain works applying microelectronic techniques.  These investigations run into the main problems of biocompatibility and conectivity and Rosa Villa shows us her letter to Santa Claus to solve them and how graphene is being of great help.

Francisco Miguel Sánchez Margallo, Scientific Director of  CCMIJU and NANBIOSIS U21. Experimental operating rooms, is co-author of the publication “Interpretation of motion analysis of laparoscopic instruments based on principal component analysis in box trainer settings” published by Surgical Endoscopy

The study results show that three new HSMAPs per hand were defined for PG and PC tasks, and two per hand for KS task. PG presented validity for HSMAPs related to insecurity and economy of space. PC showed validity for HSMAPs related to cutting efficacy, peripheral unawareness, and confidence. Finally, KS presented validity for HSMAPs related with economy of space and knotting securitya. Thus, PCA-defined HSMAPs can be used for technical skills’ assessment. Construct validation and expert knowledge can be combined to infer how competences are acquired in box trainer tasks. These findings can be exploited to provide residents with meaningful feedback on performance. Future works will compare the new HSMAPs with valid scoring systems such as GOALS.

The study has been develloped with surgical facilities of high technology that allow in vivo efficacy assays of drugs, nanomedicines, biomaterials and others, performed at unit 21 of NANBIOSIS.

NANBIOSIS U2 incorporates a new Nitrogen tank to store cells

NANBIOSIS U2. Custom Antibody Service (CAbS), is incorporating new equipment as a result of its participation in the project FICTS1420-27, selected by the MINECO for co-financing by the FEDER Program in ICTS 2014-2020.

Recently the purchase and installation and set-up of a new nitrogen tank to store cells has taken place. The storage of cell lines of monoclonal antibody-producing hybridomas is a process in which the cells are conserved when they are cooled to temperatures typically at -196 ° C in liquid Nitrogen tanks. With temperatures below -130 ° C the activity Biological ceases and storage at these temperatures is vital to keep the material unaltered. The increasing activity of the NANBIOSIS U2 the makes necesary to incorporate a new tank of liquid Nitrogen for the storage of new hybridoma lines.
