Beyond the Illusion of Controlled Environments: How to Embrace Ecological Pertinence in Research?
Eur J Neurosci
January 2025
Department of Biology, Concordia University, Montreal, QC, Canada.
Through the lens of preclinical research on substance use disorders (SUD), I propose a reflection aimed at re-evaluating animal models in neuroscience, with a focus on ecological relevance. While rodent models have provided valuable insights into the neurobiology of SUD, the field currently faces a validation crisis, with findings often failing to translate into effective human treatments. Originally designed to address the lack of reproducibility in animal studies, the current global gold standard of rigorous standardization has led to increasingly controlled environments.

Biopolymers are promising sustainable alternatives to petrochemical polymers, but the recent increase in published research articles has not translated into marketable products. Here, we discuss barriers to market entry by exploring application-specific, ecological, and economic aspects, such as the utilization of biodegradable polymers to mitigate the accumulation of microplastics. We summarize previous studies revealing how fiber surface properties and the dwell time during fiber spinning affect degradability.

The evolution of man on Earth took place under conditions of constant exposure to background ionizing radiation (IR). From this point of view, it would be reasonable to hypothesize the existence of adaptive mechanisms that enable the human organism to safely interact with IR at levels approximating long-term natural background levels. In some situations, the successful operation of molecular mechanisms of protection against IR is observed at values significantly exceeding the natural background level, for example, in cancer cells.

Rethinking the use of redox probes for the detection of electroactive proteins with electrochemical sensors modified with molecularly imprinted polymers.
Biosens Bioelectron

This study aims to demonstrate that redox couples, regardless of their electrical charges, are unnecessary for detecting and quantifying electroactive proteins using an electrochemical sensor functionalized with a molecularly imprinted polymer. Our approach involved designing a polydopamine imprinted biosensor for detecting bovine serum albumin as the model protein. Electrochemical measurements were conducted in a phosphate-buffered solution (PBS) and solutions containing the negatively charged hexacyanoferrate, the neutral ferrocene, or the positively charged hexaammineruthenium (III) probes.
