Opportunities for More Tailored Approaches to Genotoxicity Testing and Carcinogenicity Strategy for Oligonucleotide Therapeutics: Outcome of an Industry Survey.

The Oligonucleotide Nonclinical Working Group (WG) of the European Federation of Pharmaceutical Industries and Associations conducted an industry survey to understand current practices and regulatory expectations for genotoxicity and carcinogenicity assessment of oligonucleotide therapeutics (ONTs), along with historical genotoxicity testing results. The survey, involving 29 pharmaceutical and biotechnology companies, revealed a consistent absence of genotoxicity across a diverse range of oligonucleotide classes and chemistries, consistent with previous observations. Despite the lack of genotoxicity, companies continue to follow standard testing guidelines, with only limited divergence.

The safe development paradox of the United States regulatory floodplain.

In the United States, requirements for flood insurance, development restrictions, and federal buyout program eligibility rely on regulatory designation of hazardous zones, i.e., inside or outside the 100-year floodplain.

High-dimensional spectral flow cytometry of activation and phagocytosis by peripheral human polymorphonuclear leukocytes.

Polymorphonuclear lymphocytes (PMNs) are terminally differentiated phagocytes with pivotal roles in infection, inflammation, tissue injury, and resolution. PMNs can display a breadth of responses to diverse endogenous and exogenous stimuli, making understanding of these innate immune responders vital yet challenging to achieve. Here, we report a 22-color spectral flow cytometry panel to profile primary human PMNs on population and single cell levels for surface marker expression of activation, degranulation, phagocytosis, migration, chemotaxis, and interaction with fluorescently labeled cargo.

What is the economic and social return on investment for telephone cancer information and support services in Australia? An evaluative social return on investment study protocol.

Introduction: Over 50% of people affected by cancer report unmet support needs. To address unmet information and psychological needs, non-government organisations such as Cancer Councils (Australia) have developed state-based telephone cancer information and support services. Due to competing demands, evidence of the value of these services is needed to ensure that future investment makes the best use of scarce resources.
