    Allelopathy arises from the release of chemicals by one plant species that affect other species in its vicinity, usually to their detriment. Allelopathic effects have been demonstrated to be limiting factors for species distributions and ecological processes in some natural or agricultural...

    Hormesis describes the drug action of low dose stimulation and high dose inhibition. The hormesis phenomenon has been observed in a wide range of biological systems. Although known in its descriptive context, the underlying mode-of-action of hormesis is largely unexplored. Recently, the hormesis...

    Despite the substantial development and publication of highly reproducible toxicological data, the concept of hormetic dose-response relationships was never integrated into the mainstream of toxicological thought. Review of the historical foundations of the interpretation of the bioassay and...

  • HORMESIS: IMPLICATIONS FOR CANCER RISK ASSESSMENT. Borak, Jonathan; Sirianni, Greg // Dose-Response;2005, Vol. 3 Issue 3, p443 

    Current guidelines for cancer risk assessment emphasize a toxicant's "mode of action", rather than its empirically derived dose-response relationship, for determining whether linear low-dose extrapolation is appropriate. Thus, for reasons of policy, demonstration of hormesis is generally...

  • Some implications for quantitative risk assessment if hormesis exists. Sielken Jr, R.L.; Stevenson, D.E. // Human & Experimental Toxicology;1998, Vol. 17 Issue 5, p259 

    The existence of hormesis should impact quantitative risk assessment in at least seven fundamental ways. (1) The dose-reponse models for bioassay and epidemiological data should have greater flexibility to fit the observed shape of the dose-response data and no longer be forced to always be...

    Hormesis has been defined as a dose-response relationship which depicts improvement in some endpoint (increased metabolic rates, reduction in tumor incidence, etc.) at low doses of a toxic compound followed by a decline in the endpoint at higher doses. The existence of hormetic responses to...

    The development of a comprehensive database of chemical hormetic responses (i.e., U- or inverted U-shaped dose-response relationships) using objective a priori study design, statistical and study replication criteria has recently been reported.[sup ] An assessment of this database reveals the...

    When a dose–response experiment is conducted, the enhanced responses can be observed at low doses. This phenomenon is often called hormesis. The enhanced responses at low doses does not necessarily mean the existence of hormesis. It is important to conduct statistical analyses to...

  • Chemical hormesis: its historical foundations as a biological hypothesis. Calabrese, E.J.; Baldwin, L.A. // Human & Experimental Toxicology;Jan2000, Vol. 19 Issue 1, p2 

    Despite the long history of hormesis-related experimental research no systematic effort to describe its early history has been undertaken. The present paper attempts to reconstruct and assess the early history of such research and to evaluate how advances in related scientific fields affected...
