ASIO Webinar-Epidemiology Should Guide Toxicology of the Exposome

Date:Friday, April 14, 2023

Time:11:00 AM EST

Hosted By:The Association of Scientists of Indian Origin

Vrinda Kalia, MPH, PhD, Mailman School of Public Health, Columbia University.

Environmental determinants of health need to be measured and analyzed using system approaches that account for interactions between different agents that can elicit a biological response. The exposome offers a useful framework to examine the totality of exposures and their contribution to health and disease. Advances in exposure science, analytical chemistry, molecular epidemiology, and toxicology have primed us to investigate the health effects of exposure to mixtures and concomitant exposures.

This webinar will present applications of novel approaches in exposure assessment and molecular epidemiology that can identify priority chemicals associated with health outcomes using an exposomic approach. These approaches rely on high-throughput toxicology assays that can provide causal links between exposures and outcomes discovered in observational settings. Given the vast scope and complexity of the totality of exposures, letting epidemiology guide the toxicological pursuit of the exposome will ensure that human health is the focus.

ASIO Webinar-Animal Models of COVID-19 Prevention and Treatment

Date: Friday, December 17, 2021

Time: 2:30 PM EST (GMT-05:00)

Description: Rapid development of vaccines that are protective against Covid-19 infection have been at the forefront of this war against the Sars CoV2 virus. Behind the scenes, there have been a several years of efforts in developing new modalities such as mRNA vaccines that can enable such scientific breakthroughs. In addition, advances and refinement in efficacy and safety testing animal models have been successful in building strong confidence in these vaccines technologies. Vaccine development for COVID-19 involves research work with multiple species to model the varied disease outcomes in humans. With each species reacting differently to the virus, we need to learn how best to exploit both differences and similarities to human responses in studies that reveal the nature of this disease and how best to control it.

The webinar on “Modeling SARS-CoV-2 infection in animals” This webinar will focus on highlighting animal models used to study SARS-CoV-2 infection and develop prevention/treatments against COVID-19

ASIO and CTPVSS Co-Sponsored Webinar: Health Effects of Tear Gas Agents

Thursday, February 25, 2021 at 12:00-1:00pm EST

Speaker: Satya Achanta, DVM, PhD, DABT, Assistant Professor in Anesthesiology, Duke University School of Medicine, NC, USA


Over the past several decades, CS (2‑chlorobenzalmalononitrile) tear gas has been used as a common riot-control agent (RCA) by law enforcement. The use of tear gas has dramatically increased in recent years, with very large amounts released in population centers in several countries. The conflicted use in Turkey, the United States, and Hong Kong drew widespread attention in recent times.

CS is a potent chemical irritant that activates transient receptor potential ankyrin repeat 1 (TRPA1) ion channels in sensory nerve endings in the cornea, skin, mucous membranes, and airways. TRPA1 activation elicits the sensation of pain and stimulates tear secretion, blepharospasm, sneezing, cough, vomiting, and profuse secretions in the respiratory tract. TRPA1 ion channels initially serve as warning sensors alerting to the presence of potentially injurious chemical exposures. However, extended activation during escalating tear gas use can lead to the activation of a downstream neurogenic inflammatory cascade. TRPA1 pathways also contribute to inflammation in dermatitis, conjunctivitis, asthma, and pulmonary edema, among many other diseases.

CS tear gas agent has been perceived to be a sublethal incapacitant and generally safe. However, more and more doubts have been raised about the safety of CS, especially due to additional corrosive chemical effects, secondary toxic products generated by heating, and observations of arrhythmogenic effects upon stimulation of the TRPA1 pathway. Reports from several countries describe widespread respiratory injuries in protesters. Therefore, the health effects and safety concerns need to be thoroughly studied.

Time: 11:00 AM EDT

You did the hard work; networked, aced the interview and now you are in your new role. A year or two pass and you wonder...what is next? In this competitive world it is challenging to remain focused and intentional about our careers. We wonder about hitting refresh—it might be time for a pay scale raise, a new opportunity in the same company, going up the managerial track, cross-training in a different department or changing course entirely from a petrochemical to pharmaceutical company as a toxicologist. This webinar will focus on challenges faced by the early and mid-career toxicologist. Speakers will focus on key areas including: a) how to stay focused on your career goals in a high-pressure work environment, b) how to attain work-life balance during mid-career and mid-life and c) how to reign-in your career while not getting lost in the rut. Each speaker will outline their challenges; present negotiation strategies that helped them seek what they aspired for, provide practical advice and examples from their own success stories and skills set that helped them navigate through early career to their current leadership position.

Regulatory Network Models of Chemical-Induced Gene Perturbation

Date: December 15, 2017
Time: 12:00 Noon EDT

Tissue-specific network models of chemical-induced gene perturbation can improve our mechanistic understanding of the intracellular events leading to adverse health effects resulting from chemical exposure. The aryl hydrocarbon receptor (AHR) is a ligand-inducible transcription factor (TF) that activates a battery of genes and produces a variety of species-specific adverse effects in response to the potent and persistent environmental contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). Here we assemble a global map of the AHR gene regulatory network in the mouse liver from a combination of previously published gene expression and genome-wide TF binding data sets. Using various computational methods, we show that genes co-regulated by common upstream TFs in the AHR network show a pattern of co-expression. Specifically, directly-bound, indirectly-bound and non-genomic AHR target genes exhibit distinct patterns of gene expression, with the directly bound targets generally associated with highest median expression. Further, among the directly bound AHR target genes, the expression level tends to increase with the number of AHR binding sites in the proximal promoter regions. Finally, we show that co-regulated genes in the AHR network activate distinct groups of downstream biological processes, with the AHR-bound target genes enriched for metabolic processes and the AHR-unbound target genes primarily activating immune responses in the mouse liver. In summary, this work presents one approach to the reconstruction and analysis of the transcriptional regulatory cascades underlying adverse cellular response using bioinformatic and statistical tools.

Topic: ASIO—Inflammation: Can we silence the secret killer?
Recording date: Friday, October 21, 2016 12:00 PM EDT
Description: The SOT-SIG Association of Scientists of Indian Origin (ASIO) proud to announce webinar on the new developments in immunotoxicology. The webinar will highlight the role of Aryl hydrocarbon Receptor (AhR) in the inflammatory pathway, and will provide insights on the use of dietary supplements that act via AhR and contribute towards suppressing inflammation.

The speaker is Dr. Prakash Nagarkatti serve as Vice president for Research at University of North Carolina. Dr. Nagarkatti has an extensive experience on inflammation mechanisms and his recent research focus on cannabinoids and AhR ligands as potential anti-inflammatory agents.

Inflammation is a double-edged sword. On one hand, it is critical for protecting the host from infections, and plays a key role in wound healing, while on the other hand, chronic inflammation can trigger a variety of clinical disorders including allergies, autoimmune diseases, cancer, cardiovascular and neurodegenerative diseases, and obesity. There are over 80 autoimmune diseases that result from the immune attack against specific organs and tissues. Because of such wide implications of the involvement of inflammation in disease, it is not only critical to uncover as-yet-unknown immune mechanisms and mediators of inflammation but also find novel treatment modalities. Currently, there is no effective treatment against chronic inflammation. The inflammation is also impacted by exposure to environmental chemicals, toxins, nutrition, and stress. Such factors may influence inflammation through alterations in the microbiome or causing epigenetic changes. In the webinar, basic mechanisms of inflammation triggered by innate and adaptive immune system will be introduced. While aryl hydrocarbon receptor (AhR) was identified for its role in the regulation of the biochemical and toxic effects of environmental chemicals, recent studies demonstrated that AhR ligands can also play a key role in suppressing inflammation. In the webinar dietary compounds that can act as AhR ligands and suppress inflammation will be discussed.

The webinar will address the application of “omics” approaches as biomarker tools in drug discovery and development. Understanding transcription (mRNA, miRNA), translation (and its modifications) and the metabolites are fundamental to interrogate the mechanistic toxicity of complex human disease. The insights lend itself to develop biomarker signature for understanding mechanism of action of drug and its efficacy, patient enrichment and stratification in clinical trials. Thereupon, the biomarker platforms and technologies have evolved to provide practical applications as well as less resource-intensive approaches. The presentation will provide broad perspectives and examples on the “omics” approaches and their utilization in drug discovery and development as biomarkers.

Dr. Shashi Ramaiah is pioneer in the field of biomarker “Omics” technology and currently serving as the head of Translational Biomarkers at Pfizer Biotherapeutics in Cambridge, MA. He received his doctoral degree in veterinary medicine in 1992 from University of Agricultural sciences, Bangalore, India and received PhD in Toxicology from University of Lousiana at Monroe in 1999. He completed his clinical pathology residency at University of Florida, Gainesville in 2002 and became faculty of Texas and A & M College of Veterinary Medicine. He obtained an independent NIH funded research program on alcoholic liver disease and trained several graduate students, residents and post-doctoral fellows. He is board certified in clinical Pathologist (DACVP) and toxicologist (DABT). He has published more than 50 peer-reviewed journal articles, manuscripts and book chapters. Dr. Ramaiah transitioned from academia to Pfizer.Inc in 2008 as Translational biomarker head and is currently responsible for scientific leadership, supervision of laboratory operations and development of translational pharmacology and safety biomarker strategies to support projects across different therapeutic areas and modalities in Pfizer-Biotherapeutics portfolio.
