Evaluation of a New Design of Antireflux-Biodegradable Ureteral Stent in Animal Model

Francisco Miguel Sánchez Margallo, Assistant Director of NANBIOSIS and Scientific Director of JUMISC, is  co-authors of de article “Evaluation of a New Design of Antireflux-biodegradable Ureteral Stent in Animal Model” published by Urology.

The research were carried out in the NANBIOSIS units in the JUMISC. The purpose was to determine the effects in urinary tract of a new antireflux-biodegradable ureteral stent. Thirty six ureters belonging to 24 pigs were used. The study began with endoscopic, nephrosonographic, and fluoroscopic assessments. Three study groups of ureters (n = 12) were then specified. In group I, a biodegradable antireflux ureteral stent (BDG-ARS) was inserted in the right ureter of 12 pigs. Group II comprised the left ureter of the same animals, in which a double-pigtail stent was placed for 6 weeks. Group III ureters, belonging to 12 additional animals, were subjected to a ureteropelvic junction obstruction model that was then treated by endopyelotomy and stenting with BDG-ARS. Follow-ups were performed at 3-6 weeks and at 5 months.  As result of the research none of the ureters receiving the BDG-ARS showed any evidence of vesicoureteral reflux (VUR). BDG-ARS degradation took place in a controlled and predictable fashion from the third to the sixth weeks, and no obstructive fragments appeared. No differences were found between groups I and II regarding passive ureteral dilation, but significant differences were found regarding VUR and ureteral orifice damage. BDG-ARS always maintained distal ureteral peristalsis. BDG-ARS in group III showed a 50% positive urine culture rate and a 16.6% migration rate in both BDG-ARS groups.

The scientists have demonstrated that morbidity associated with ureteral stents might be reduced as BDG-ARS avoided VUR and bladder trigone irritation, and the polymer combination and stent-braided design achieved a consistent biodegradation rate with no obstructive fragments and with uniform degradation between the third and the sixth weeks. Consequently, morbidity associated with ureteral stents might be reduced.

NANOLIGENT, the first drug designed to eliminate metastases stem cells

NANBIOSIS researchers have developed a nanomedicine for the treatment of metastases by the selective elimination of tumor stem cells. It is a system based on nanoparticles that transport a chemotherapeutic drug and release it into cancer cells.

The research team, led by Esther Vázquez and Antonio Villaverde, Strategy Director of NANBIOSIS U1. Protein Production Platform (PPP), in the IBB-UAB, and Ramon Mangues, Scientific Director of NANBIOSIS U18. Nanotoxicology Unit, in the Sant Pau Hospital, have already created a prototype of the drug and have conducted in vivo trials in animal models of colorectal cancer. They have demonstrated their effectiveness, selective biodistribution and low toxicity.

To promote the development of the drug towards the clinic, the reserachers have created Nanoligent a start-up company, based in Barcelona, led by Manuel Rodríguez, a professional with experience in the field of investment and the creation and growth of biotech companies. The technology is patented in Europe and USA and has been licenced to Nanoligent

The therapy created by the researchers is aimed at blocking the development of metastasis, mainly of colorectal cancer, through new strategies aimed at certain cell types. It consists of a new drug administration system based on protein nanoparticles that selectively conduct the therapeutic agent in tumor cells. The drug acts only on cancer cells, because it is based on the specific interaction between a protein present in the nanoparticle and a cellular receptor (CXCR4), which is overexpressed in tumor cells. “This interaction is crucial, because it allows attacking only tumor cells and not healthy cells, thus avoiding secondary effects derived from classical chemotherapy,” emphasizes Antonio Villaverde.

The CXCR4 receptor is overexpressed in many types of tumors, so that “this technology can be directed to the treatment of different types of neoplasms in addition to colorectal cancer and derived metastases, such as lymphoma, leukemia or endometrial cancer, in animal models already available to the group of Sant Pau “, comments Ramon Mangues. In addition, nanoparticles are compatible with a huge variety of possible drugs and therefore they become highly versatile vehicles that can carry a wide range of therapeutic molecules.

“There is an urgent need for more effective and personalized treatments for cancer. The toxicity and the lack of efficacy of conventional drugs are pushing alternative experimental strategies directed and designed to achieve only defined cell types. Nanoparticles, thanks to their capacity for penetration, dissemination and functionality, offer a promising nanomedical landscape to create new drugs,” explains Esther Vázquez.

“In this direction, the technology of Nanoligent opens a new door in anti-pelagic therapy, as it allows to design a treatment with greater cellular specificity than that of existing treatments, while offering greater biosecurity and biodegradability and lower toxicity,” he said. Antonio Villaverde points out.

Currently, there are no drugs in the market that selectively eliminate metastatic stem cells. Although Nanoligent technology is still under development, researchers say they have a lot of potential and consider that it could have a high clinical impact as regulatory trials are overcome.

Rey Jaime I Award of New Technologies to Ramón Martínez Mañez

Ramon Martínez Mañez, Scientific Director of NANBIOSIS U 26 Biomedical Applications II and Scientific Director of CIBER-BBN, has received the Rey Jaime I Award of New Technologies 2018.

Rey Jaime I Awards are granted (in xis cathegories) to people who stand out in their field of work and who have developed most of their professional activity in Spain. Candidates must be nominated by third parties and must prove their qualities. They are recognized as the most prestigious awards for the activity carried out in Spain. It is one of the best paid prizes in the country. Each of them is endowed with 100 thousand euros and a gold medal. The winners of each category are committed to allocate a part of the prize amount to research and entrepreneurship in Spain.

The jury  of the Jaime I Award for New Technologies (integrated by 18 Nobel prizes) has valued Martínez Mañez “exceptional contributions” in the development of nanosensors with applications in food technology and medicine. Among them, he has indicated the colorimetric labels for the assessment of the freshness of food, the devices for the simple detection of the Human Papilloma Virus (HPV) and the nanostructures of controlled release of active principles against the fruit fly.

In addition, the jury remarked that the “high scientific quality” of his work has been applied in different technological fields with social impact.

Ramón Martínez-Máñez is a university professor, director of the Interuniversity Research Institute for Molecular Recognition and Technological Development (IDM).  He has published a total of 393 articles in different scientific journals and has a very prominent presence in the most significant journals in the field of mustidisciplinary chemistry, such as the Journal of the American Chemical Society or Angewandte Chemie International Edition Nature Communicationsand, having been cited more than 17,000 times (web of Science, 19,874 times in Google Scholar), with an average of more than 42 citations per article, and has an h index of 60 (web of Science, h index of 63 in Google Scholar). Moreover, he has coordinated 99 national and European projects and has achieved “very reliable” sensors for clinical diagnosis, detect changes in the environment and control food quality, with applications in agriculture and nanomedicine.

Currently, his research group is working on the development of nanometric devices with “molecular doors” for the controlled release of drugs. The mesoporous nanoparticles studied are able to retain a charge within their pore system and deliver it when applied a chemical, physical or biochemical stimulus. These particles have been used, for example, for the selective release of cytotoxins for the elimination of cancer cells and bacteria, and also for the release of certain drugs in senescent cells. In addition, the group of Martínez Máñez works in the development of molecular probes for the detection, through changes in color and fluorescence, of elements of environmental and biomedical interest such as drugs, nerve gases, certain types of cells, etc.

Also María Vallet Regí, head of the CIBER-BBN group at the Complutense University of Madrid, has been awarded the Rey Jaime I of Basic Research. Thus, two of the six Awards granted by this institution this year recognize the work of researchers of the CIBER-BBN, partner of NANBIOSIS.

DRIVE Project: Artificial Biopancreas for Type I Diabetics

On Saturday, June 2, in the auditorium of the Artium museum in Vitoria, a meeting was held for patients with diabetes, organized by the group of European researchers of the DRIVE project with the aim of conecting patiens with researchers.

The event was organized by the NanoBioCel research group of the CIBER-BBN and the University of the Basque Country, led by José Luis Pedraz, Scientific Director of   NANBIOSIS Unit 10, Drug Formulation, which participates, through the CIBER BBN and the ICTS Nanbiosis, in the Drive Project  focused on pancreatic  cell transplantation  and the development of biomaterials and new surgical devices that improve the transplantation and survival of insulin-producing pancreatic islets for the treatment of diabetes.

Dr. Pedraz explained for EIBT.eus Radio euskadi the aim of the DRIVE project: the transplantation of the cells of the pancreas, which consists of isolating the insulin-producing cells from a donor’s pancreas and implanting them in the patient with daibetes type I, not directly, but introduced into an artificial bio-pancreas by minimal invasive surgery . “Nowadays– explains Dr. Pedraz- obtaining pancreatic cells from stem cells or IPS cells is a not yet controlled process but it is an alternative source of insulin-producing cells. In the DRIVE project the most priority objective is to take the donor cells and introduce them into a device that will allow the patient to produce and release insulin in a more physiological way. In a second phase, it is intended to use differentiated insulin producing cells from the patient’s own cells, thus alleviating the shortage of  donors”.
