Peer-Reviewed
Publications

Open access, peer-reviewed publications ensure that knowledge is a public good. HESI believes that accessible research is critical for equitable engagement, diverse collaboration, and increased interdisciplinary conversation. We strive to achieve open access on all publications, and more than 200 publications from HESI programs have been published in the last decade.

Permitted Daily Exposure Limits for Noteworthy N-Nitrosamines

A genotoxic carcinogen, N-nitrosodimethylamine (NDMA), was detected as a synthesis impurity in some valsartan drugs in 2018, and other N-nitrosamines, such as N-nitrosodiethylamine (NDEA), were later detected in other sartan products. N-nitrosamines are pro-mutagens that can react with DNA following metabolism to produce ...

Methodological Considerations for Measuring Biofluid-Based MicroRNA Biomarkers

MicroRNAs (miRNAs) are small non-coding RNA that regulate the expression of messenger RNA and are implicated in almost all cellular processes. Importantly, miRNAs can be released extracellularly and are stable in these matrices where they may serve as indicators of organ or cell-specific toxicity, disease, and biological ...

Comparisons of PNEC Derivation Logic Flows Under Example Regulatory Schemes and Implications for ecoTTC

Derivation of Predicted No Effect Concentrations (PNECs) for aquatic systems is the primary deterministic form of hazard extrapolation used in environmental risk assessment. Depending on the data availability, different regulatory jurisdictions apply application factors (AFs) to the most sensitive measured endpoint to ...

An International, Inter-Laboratory Ring Trial Confirms the Feasibility of an Open Source, Extraction-Less “Direct” RT-qPCR Method for Reliable Detection of SARS-CoV-2 RNA in Clinical Samples

RT-qPCR is used world-wide to test and trace the spread of SARS-CoV-2. Extraction-less or direct RT-PCR is an open-access qualitative method for SARS-CoV-2 detection from nasopharyngeal (NP) or oral pharyngeal (OP) samples with the potential to generate actionable data more quickly, at a lower cost, and with fewer experimental ...

Options for Imaging Cellular Therapeutics In Vivo: A Multi-Stakeholder Perspective

Cell-based therapies have been making great advances toward clinical reality. Despite the increase in trial activity, few therapies have successfully navigated late-phase clinical trials and received market authorization. One possible explanation for this is that additional tools and technologies to enable their ...

Ontogeny of Hepatic Transporters and Drug-Metabolizing Enzymes in Humans and in Nonclinical Species

The liver represents a major eliminating and detoxifying organ, determining exposure to endogenous compounds, drugs, and other xenobiotics. Drug transporters (DTs) and drug-metabolizing enzymes (DMEs) are key determinants of disposition, efficacy, and toxicity of drugs. Changes in their mRNA and protein expression levels ...
