From the President
Greetings HOT Members!!!
This is the last newsletter before I retire as the
President of HOT-SOT. It has been a huge
pleasure to serve as your leader in 2013-2014. I
have enjoyed working with the HOT Board of
Officers as councilor and Vice President since
2010.
This year is our 10th anniversary as Special
Interest Group. It is so impressive to see the
progress that has been made in our organization
since then: the increased visibility and productivity
of our members in the Society and the
opportunities that have been created as a result of
the foundation of HOT and its recognition as a SIG
by the SOT.
And the progress continues. This year in the
53rd SOT Annual Meeting in Phoenix AZ, the HOT
awarded 5 trainees of Latino origin with plaques
and budget to attend the meeting. We had a new
session in which HOT trainees had the opportunity
of having breakfast and interacting on a “one on
one” manner with several more experienced
members of HOT and we co-chaired a brand new
event titled “The Global Hot Topics Event” in which
speakers from different parts of the globe (Brazil,
Czech Republic and USA) discussed local air
pollution and child development issues.
Our reception in the Annual Meeting was a
tremendous success, with more than 100 people
attending, it took place in the Arizona Latino Arts
and Cultural Center. In a casual and friendly
environment we were honored to have Dr. Gonzalo
Diaz as the keynote speaker. Dr. Diaz is Professor
HOT keeps moving forward
of Toxicology in the College of Veterinary Medicine,
at the National University of Colombia, and is the
award recipient of the “2014 Global Senior Scholar
Exchange Program”. After our formal program and
presentation of the travel awards, we mingled and
had fun at the best Latino style: with plenty of food,
drink, music and dancing!!!
I am very glad I had the opportunity of helping
in making 2013-2014 a very productive year with
lots of accomplishments for our organization. I
would like to acknowledge one more time the
wonderful Board of Officers with whom I worked
with: Catherine Rondelli (Student Rep), René
Viñas (Postdoctoral Rep), Jorge Muñiz Ortiz,
Azita
Cuevas,
Betzabet
Quintanilla-Vega
(Councilors), María E. Gonsebatt (Councilor to
Sister Organizations), Ranulfo Lemus Olalde
(Treasurer), Elena Hernández-Ramón (Secretary),
Minerva Mercado-Feliciano (Vice PresidentElect), Verónica Ramírez Alcántara (Toxelances,
Editor-in-Chief), Linval DePass (Vice President)
and Leslie Recio (Past President). As always, I
am available to each one of you, if you need any
assistance.
I wish the best of lucks to the new HOT Board.
I will be involved with them as Past President to
keep working for our great organization.
THANK YOU, GRACIAS, OBRIGADA, for making
HOT a huge success!!!!

Nanotoxicology: Present and Future
as Global Emergent Field

Nanotechnology, as an emergent discipline has
grown as a multibillion-dollar industry worldwide.
According to Wodrow Wilson Center (2014), over this
year there have been produced more than 1600
nanotechnology enabled products, released to the
environment in cosmetics, medical products,
electronics, etc. Furthermore, there are many natural
and anthropogenic sources of nanoparticles, and these
materials can be unintentionally liberated as fumes,
aerosols and ashes from incinerators, electric motors,
internal combustion engines, etc.
During the 53rd SOT Annual Meeting the
continued education courses were a great resource to
get updated on different topics related to toxicological
approaches. On this article we want to highlight the
relevance of the continuing education course entitled
“Nanotoxicology: Past Achievements, Future
Challenges and Potential Solutions”. The lectures
of this course were provided by Saber Hussain
(chairperson, US Air Force, Wright-Patterson AFB,
Dayton, OH), David Warheit (chairperson, DuPont
Haskell Laboratories, Newark, DE), Laura BraydichStolle, Christin Grabinski (both from US Air Force),
Kristen Comfort (University of Dayton) and Charles
Geraci Jr. (NIOSH). They are well recognized in the
field of nanotoxicology and introduced us to the most
important aspects that should be prioritized when the
toxicological effects of nanomaterials are considered.
If you want to collaborate
with short articles, news or
notes related with
Toxicology, send it to
René Viñas (incoming
Toxenlaces Editor) at
[email protected] for
inclusion in upcoming
issues.
Dr. David B. Warheit in his lecture entitled
“Importance of Robust Nanomaterial Characterization
as a Necessary Prerequisite for Evaluating the Results
of In vivo Nanotoxicity Studies” showed the importance
of performing an exhaustive physical/chemical
characterization upon nanomaterials to determine
aspects such as size, morphology, crystallinity,
composition, aggregation state, particle surface
reactivity, etc. These paramount parameters directly
influence the toxicological effects that nanomaterials
may have on in vitro or in vivo models subjected to
exposure. Dr. Warheit compared the toxic effects of
TiO2, ZnO and carbon nanostructures on lung tissue
and on BALF cells. He emphasized that the knowledge
of the applied or produced nanomaterial is crucial to
understand their behavior on living beings and be able
to detect their nanotoxic effects. The take home
message was that if we want to publish an article in a
toxicological journal presenting a nanomaterial with
poor characterization, most probably the article will be
rejected.
Laura K. Braydich-Stolle and Saber M. Hussain in
their lecture entitled “Nanotoxicology: What has been
done for the past Decade” described silver
nanoparticles as a reference material and presented
their in vivo and in vitro toxicological effects. Silver
nanoparticles are of great relevance because they are
broadly applied in the industrial sector. For example,
they can be found in hygienic products (soap,
toothpaste, shampoo, etc) and medical products
(catheters and bandages). However, a direct
correlation between the diameter of silver particles and
their toxicity has been established. Some mentioned
toxicological effects were lung and kidney damage and
oxidative stress in mouse brain. Dr. Braydich-Stolle
and Hussain mentioned that in the study of
nanomaterial toxicity, the challenge is to define what
factor made them toxic (dose, homogeneous uptake)
or if the toxic effects are caused by nanoparticles or by
the ions released by such nanomaterial.
Dr. Grabinski introduced us to the main concepts
related to nanoparticle dosimetry. She explained the
fundamentals of nanoparticle dosimetry challenges,
such as alteration of physical/chemical properties,
aggregation of nanoparticles and their interaction with
biological components. Dr. Grabinski also talked about
the approaches for comprehensive nanoparticle
dosimetry, such as target dose, dose metric, dose
methodology and characterization. She emphasized
that for the delivery of nanoparticles to the target,
realistic exposure methods and consideration of
alternative exposure systems is important, and showed
some in vivo and in vitro methodologies to determine
the dose of nanoparticles that can reach the target
On lecture entitled “Unresolved Challenges:
Biological Models and Future Directions Overcome
these challenges”, Dr. Kristen K. Comfort discussed
that it is necessary to improve the biological models
employed to determine the toxicity of nanomaterials.
There has been a broad development on the
characterization,
synthesis
and
dosimetry
methodologies for nanoparticles. However, it is
essential to perform more in vitro experiments that
could simulate in vivo systems. Because there is a
broad of differences between in vivo and in vitro
models, she proposed to improve in vitro models with
co-cultures, to use more type of cell lines, to perform
3-D in vitro models and to perform more experiments
with more representative physiological environments.

Finally, Dr. Charles L. Geraci, with the lecture
entitled “Occupational Hazards and Risks in the
Workplace: Where We Stand”, discussed the problems
related to pollution with nanomaterials in the
workplace. He emphasized the urgent need to
establish guidelines to prevent and control the
exposure of human beings to nanomaterials, and the
toxicological studies to evaluate their chronic effects in
workplaces, their quantity on air, etc. Dr. Geraci
addressed that, because of the nature of
nanomaterials changes when they are released to the
environment, it is urgent to obtain more information
about nanomaterials in occupational sectors.
The relevance of the information provided by the
speakers is broad considering that we all are exposed
to toxicological agents at nanoscale level almost at
daily bases. The United States of America and the
European Union previously have established different
rules and standards to detect, characterize and assess
the toxicology of nanomaterials in products of daily use
and released in industrial emissions. However, in most
Latin American countries these strategies are nonexistent or are beginning to emerge, not to mention
that the current regulatory limits might not be relevant
at the nanometric level, because of the change of
scale of the materials modifies their reactivity.
Therefore, it is a priority, as representatives of the
toxicology in Latin America, to join efforts and to
establish regulations according to international
standards, provided by the pioneers in nanotoxicology.
Certainly, we have the duty to guide the society to find
alternatives and strategies to regulate the issuance
and evaluation of new pollutants, as the
nanomaterials, whose properties are still not fully
understood, to prevent their adverse effects on human
health and the environment.

HOT’s Event to Students and Trainees members
During the past SOT Annual Meeting, the HOT organized a breakfast
event focused on the different career paths available for toxicologists. This
was a great opportunity for our students and trainees to get information
about how to leverage opportunities and strength areas throughout the job
hiring process and early career life, and to know about training
opportunities available at the National Institutes of Health for trainees of
minority origin. If that was not enough, those presentations were followed
by roundtable discussions in which mentees had the opportunity to
xxxxxxx
directly interact with mentors of Latino origin
from a variety of sectors including
industry, government, and academia.
This event was hosted by Dr. Betina Lew (HOT President, Church and
Dwight, Corp.) and Dr. Elena Hernandez-Ramon (HOT Secretary, NIH). The
round tables were presided by Dr. Azita Cuevas (HOT Councilor, Pepsico), Dr.
Pedro del Valle (HOT Past President, FDA), and Dr. Mari S. Stavanja (CoFounder and HOT Past President, Celanese).

Note From the Editor
Dear HOT members,
This is my last issue of Toxenlaces as the Editor-in-Chief. It has been a pleasure to serve you by releasing
every two months this newsletter to keep you informed about what is going on in our organization. I hope you
enjoyed reading each edition. During this time as Editor I got to meet a lot of our members, if not in person but by
email, and not only from United States, but also from Mexico, Brazil,
Spain; so base on that I could say that I traveled a lot!!
I also was able to re-connect with old friends, as for example René
Viñas, I met him in 2005, and because of Toxenlaces I met him again
two years ago. In fact, René will be the new Editor-in-Chief of our bimonthly newsletter. I know he will continue delivering valuable material
to us with news from our members, interviews from recognized Hispanic
toxicologists and scientific articles from our community.
I want to express my gratitude to all those that helped me during my position, especially to Minerva MercadoFeliciano (past Editor), who trusted on me for this role and trained me to be a good one. Thank you also to all those
members that collaborated with Toxenlaces by being interviewed or sending me material to be published.
Keep enjoying Toxenlaces!
