Salivary alpha-amylase stress reactivity in advanced-aged marmosets (Callithrix jacchus): Impacts of cognitive function and oral health status.

Salivary alpha-amylase (sAA) is an enzyme found in saliva and is considered a noninvasive biomarker for sympathetic nervous system activity. While a wide range of sAA activity in response to stress has been reported in nonhuman primates, the effects of stress on sAA activity in common marmosets are still unknown. We tested the hypothesis that advanced age and cognitive function may have an impact on stress-related sAA reactivity in marmosets.

Selection of the candidate compound at an early stage of new drug development: retrospective pharmacokinetic and metabolic evaluations of valsartan using common marmosets.

Valsartan is an antihypertensive drug that was developed using common marmosets () in pivotal toxicity studies as a non-rodent species. The aim of the present study was to investigate the utility of marmosets in the candidate selection of this drug from a pharmacokinetic and metabolic viewpoint.Valsartan, as well as three other angiotensin II type-I receptor blockers, assumed as competitive candidates, were administered to common marmosets.

Anatomical, behavioural and physiological analyses of craniofacial development by cineradiographic imaging in marmosets.

Background: Non-human primates are the closest animal models to humans regarding genetics, physiology and behaviour. Marmoset monkeys in particular are one of the most versatile species for biomedical research.

Objective: To assess the craniofacial growth and development of the masticatory function in the common marmoset (Callithrix jacchus), from birth to the fourth month of life through minimally invasive cineradiographic imaging.

Characterization of oral microbiota in marmosets: Feasibility of using the marmoset as a human oral disease model.

With rapid aging of the world's population, the demand for research, for a better understanding of aging and aging-related disorders, is increasing. Ideally, such research should be conducted on human subjects. However, due to ethical considerations, animals such as rodents and monkeys are used as alternatives.
