Jacketed telemetry in rats: a novel non-invasive method for cardiorespiratory phenotyping during treadmill exercise.

The development of alternative methods for monitoring cardiorespiratory function without restraint or surgical implantation is attracting growing interest for both ethical and scientific reasons. For this purpose, a new non-invasive jacketed telemetry tool consisting in a radio device maintained in a jacket worn by the animal was previously developed to improve cardiorespiratory monitoring. It allows simultaneous monitoring of cardiac activity by surface electrocardiagram, respiratory function by respiratory inductive plethysmography, and locomotor activity by accelerometry.

Inductive plethysmography in rats: towards a new standard for longitudinal non-invasive cardiac output monitoring in preclinical studies.

Objective: Cardiovascular function assessment is most often a mandatory requirement in preclinical studies in all industrialized countries. The invasiveness and impact of the monitoring devices used on animals have to be reduced as far as possible for scientific as well as ethical reasons. In humans, inductive plethysmography (IP) is a commonly used wearable non-invasive technology based on volume recordings.

High-resolution respiratory inductive plethysmography in rats: validation in anesthetized conditions.

Unlabelled: Respiratory monitoring is often required in experimental physiological and pharmacological studies in rodents. Currently, the mostly used techniques are direct measurement of airflow on intubated animals and whole body plethysmography.

Objective: Although the reliability of these methods has been broadly demonstrated, they also have several drawbacks such as invasiveness, high cost of use or confinement of the animals.

Use of Space and Human Rights: Planning Dementia Friendly Settings.

Environmental psychology has been a topic of great interest for many researchers in the field of aging and dementia. Thus, several orientations can be identified in the contemporary scientific literature concerning environmental design for people with dementia. In this article, we discuss recent research on environmental design models for people with dementia and propose an approach referring to the concept of use of space and human rights.
