Environmental enrichment for primates in laboratories [PDF]

Advances in Science and Research, 2011
Environmental enrichment is a critical component of Refinement, one of the 3Rs underlying humane experimentation on animals. In this paper I discuss why primates housed in laboratories, which often have constraints of space and study protocols, are a ...

Environmental enrichment and neurotransmitter receptors [PDF]

Behavioral and Neural Biology, 1982
The extent of high affinity, specific binding of several pharmacological agents to brain membrane fractions derived from rats reared in an environmentally enriched or impoverished environment has been assayed. The binding of all labeled agents studied was not significantly altered in cerebellar, subcortical, or cortical membranes by the rearing ...

Metal enrichment processes [PDF]

, 2008
There are many processes that can transport gas from the galaxies to their environment and enrich the environment in this way with metals. These metal enrichment processes have a large influence on the evolution of both the galaxies and their environment.

Selecting and Testing Environmental Enrichment in Lemurs [PDF]

Frontiers in Psychology, 2019
Environmental enrichment has become a standard tool for improving the welfare of animals in zoos. Two critical steps in the manipulation of environmental enrichment are (1) selection of objects/procedures and (2) evaluation of their effects.

Environmental Enrichment for Laboratory Rodents [PDF]

ILAR Journal, 2005
Modernization of housing and husbandry techniques for rodents has minimized confounding variables. The result has been vastly improved health maintenance and reproducibility of research findings, advances that have decreased the numbers of animals needed to attain statistically significant results.

Developing appropriate environmental enrichment strategies for broiler breeders [PDF]

Scientific Reports
There is a recognised need for environmental enrichment strategies to be developed for broiler parent stock. We evaluated the use and tested preferences for three forms of enrichment in commercial broiler breeder housing: (1) perches (platform perches ...

Reversal of cocaine addiction by environmental enrichment [PDF]

Proceedings of the National Academy of Sciences, 2008
Environmental conditions can dramatically influence the behavioral and neurochemical effects of drugs of abuse. For example, stress increases the reinforcing effects of drugs and plays an important role in determining the vulnerability to develop drug addiction.

Application of CO₂-Switchable Oleic-Acid-Based Surfactant for Reducing Viscosity of Heavy Oil

Molecules, 2021
CO2-switchable oligomeric surfactants have good viscosity-reducing properties; however, the complex synthesis of surfactants limits their application. In this study, a CO2-switchable “pseudo”-tetrameric surfactant oleic acid (OA)/cyclic polyamine (cyclen)

Prolonged Environmental Enrichment Promotes Developmental Myelination

Frontiers in Cell and Developmental Biology, 2021
Postnatal neurodevelopment is profoundly influenced by environmental experiences. Environmental enrichment is a commonly used experimental paradigm that has uncovered numerous examples of experience-dependent plasticity in health and disease.
