Some of the members of the N&N Group at the JIPI conference in Barcelona

UB paranimf

Today at the Paranimf of the Universitat de Barcelona there is the Jornada d’Investigadors Predoctorals Interdisciplinària” (JIPI) -Interdisciplinary Meeting of Predoctoral Researchers-, from 8.30 am to 8 pm. 

The JIPI is a meeting point for PhD researchers in Catalonia, where they can present their work and meet researchers of different fields.

Apart from the flash talks, divided in different topics (Applied sciences, Social sciences, Life sciences and Humanities), and given by 1, 2 or 3 speakers together, the attendees can participate in a speed-networking session, and in interesting debates. The topics of the debates of this year are “Women in research”, “Doctors and the private sector” and “Education in science”.

Irene, Ma Zheng, Sole, Júlia, Pengmei Yu and Alex

Irene Anton, Sole Roig and Ma Zheng from the N&N Group have attented the conference. From ICMAB, Júlia Jareño and Alexander Stangl, who presented the talk “Hot future for cold superconductors”, won the award of their session. Congrats!

Prof. Stephen Sturzenbaum will give an ICMAB Lecture on toxicity of metals on biological systems

It is a pleasure for us to invite you to the ICMAB Lecture entitled: “Juggling essential and toxic metals – a worm’s eye view of a Toxicogenomic challenge”

By Prof. Stephen Sturzenbaum from the group of Toxicogenomics from King’s College London (UK).

Date: Friday, January 20th
Time: 12.00 pm
Place: ICMAB – Sala d’actes Carles Miravitlles

Abstract: Some metals are exclusively toxic to biological systems and classified as being non-essential, others are essential for life. Nevertheless, above certain threshold concentrations all (including the essential ones) become toxic. Homeostasis of essential elements and detoxification of non-essential elements are thus vital drivers of well-being, longevity and survival. By exploiting genomic, transcriptomic and toxicological tools within the model nematode C. elegans we identified and characterized intricate pathways that not only form the foundations of metallomics but facilitate further explorations within the field of nanomaterials.

Short bio: Professor Stephen Sturzenbaum holds a personal chair in Toxicogenomics at King’s College London and was recently awarded a Senior Doctorate (DSc) from Cardiff University for his work on “Toxicogenomics on Terrestrial Worms”. Stephen pioneered the use of molecular genetic tools in the common earthworm, and in doing so was instrumental in establishing the earthworm as a sentinel soil macroinvertebrate model organism of environmental importance. Stephen’s second stream of work has focussed on promoting the use of the more established C. elegans model organism to address the burgeoning themes of metallobiology, toxicogenomics and nanoparticle toxicology. Laura González, from our group, who did her thesis on evaluating nanoparticles’ toxicity on C. elegans, did an internship at his laboratory during Feb-May 2016

Today Joel N. Meyer from Duke University gives a Seminar at ICMAB on “Mechanisms of uptake and toxicity of Ag NP in C. elegans”

Prof. Joel N. Meyer will give a Seminar entitled “Mechanisms of uptake and toxicity of silver nanoparticles in Caenorhabditis elegans“, today, December 15, at 12 pm at ICMAB Conference Room Carles Miravitlles.

Prof. Joel N. Meyer is Associate Professor and Director of Graduate Studies at Nicholas School of the Environment and Center for the Environmental Implications of Nanotechnology (CEINT), at Duke University, NC, USA. 

Short abstract:

Engineered nanomaterials offer great opportunities due to their novel properties. However, there is concern that these novel properties may also result in deleterious effects on human and ecological health that are difficult to predict based only on an understanding of the chemical makeup. We tested a number of nanoparticles (NPs) for toxicity in the nematode model Caenorhabditis elegans, and found that certain silver NPs (AgNPs) were the most toxic of the NPs that we had tested. We therefore extended our studies to characterize environmental factors that might alter AgNP toxicity, as well as the uptake and mechanism of toxicity of AgNPs in C. elegans.

Because much AgNP waste is expected to end up in aquatic ecosystems, we tested the influence of environmental variables on toxicity. We found that higher ionic strength, the presence of natural organic matter, and sulfidation of the AgNPs (expected to occur in many environments after AgNP release) all significantly reduced Ag NP toxicity. Using physicochemical, genetic, and pharmacological rescue approaches, we found that the most toxic AgNPs -generally, the smallest- caused their effects largely via dissolution. Some AgNPs (typically less soluble due to size or coating) also caused toxicity via generation of reactive oxygen species, an effect specific to nanoparticulate silver. This effect was masked by the toxicity of silver ions except when dissolution was very limited. The toxicity of the tested AgNPs was almost never greater than would result from complete dissolution of the same mass of silver. We also found that endocytosis was an important mechanism for AgNP uptake. However, the specific mechanisms by which AgNPs or released silver ion cause toxicity remain unclear. Because AgNPs are used to kill microbes, and mitochondria are endosymbiotic descendants of bacteria, current studies are focused on testing the possibility that AgNPs cause some of their toxicity via disruption of mitochondrial function.

Anna Roig attends the B·Debate on Imaging for Life: from Molecules to Diagnostics and Therapy at CosmoCaixa

Anna Roig will attend the B·Debate on Imaging for Life. From Molecules to Diagnostics and Therapy, that takes place on November 8-9 at CosmoCaixa (Barcelona). 

The scientific leaders of this B·Debate are Francesc Xavier Avilés, from the Institut de Biotecnologia i Biomedicina (IBB) – Universitat Autònoma de Barcelona (UAB) and Boris Turk, from  “Jožef Stefan” Institute (IJS) – Ljubljana University, Slovenia. 

The objective is to bring together national and international experts in the field to discuss the future perspectives and strategies for the current challenges on molecular imaging.

The B·Debate will focus on molecular, cell, tissue and small animals research, and to their biomedical applications, including non-invasive diagnostic, imaging-guided surgery, multimodal scanning and theranostics.

For sure this B·Debate will be useful for Anna and for the group, since imaging is a powerful tool to study the interaction of inorganic nanoparticles with living organisms, such as C. elegans, which is the topic of Laura González thesis, for example. 

This B·Debate is an iniciative of Biocat and l’Obra Social “la Caixa”, together with the Institut de Biotecnologia i Biomedicina (IBB) – Universitat Autònoma de Barcelona (UAB) and Jožef Stefan” Institute (IJS) – Ljubljana University (Slovenia).
