Metabolic consequences of long-term rapamycin exposure on common marmoset monkeys (Callithrix jacchus).
Rapamycin has been shown to extend lifespan in rodent models, but the effects on metabolic health and function have been widely debated in both clinical and translational trials. Prior to rapamycin being used as a treatment to extend both lifespan and healthspan in the human population, it is vital to assess the side effects of […]

Characterization of long-term motor deficits in the 6-OHDA model of Parkinson’s disease in the common marmoset
Research aimed at developing new therapies for Parkinson’s disease (PD) critically depend on valid animal models of the disease that allows for repeated testing of motor disabilities over extended time periods. We here present an extensive characterization of a wide range of motor symptoms in the 6-OHDA marmoset model of PD when tested over several […]

Technical note: Validation of an automatic recording system to assess behavioural activity level in sheep (Ovis aries)
The welfare of an individual can be assessed by monitoring behavioural changes, such as inactivity, that may indicate injury or disease. In this study we validated the Actiwatch Mini® activity monitor (AM) for automatic recording of behavioural activity levels of nine Texel ewes. The AM devices were attached to collars placed around the necks of […]

Meal size and feeding management strategies influence the daily rhythm of total locomotor activity in horses (Equus caballus)
Keeping and management of horses can induce changes to instinctive and innate behavioural patterns. We investigated the effect of five different management conditions in five groups of horses. All groups were housed in individual boxes under natural environmental and lighting conditions. They were fed three times a day (07:00, 12:30 and 20:00) and had free […]

Early and progressive circadian abnormalities in Huntington’s disease sheep are unmasked by social environment
Insidious changes in behaviour herald the onset of progressive neurodegenerative disorders such as Huntington’s disease (HD), sometimes years before overt symptoms are seen. Sleep and circadian disturbances are particularly disruptive symptoms in patients with neurological disorders, but they are difficult to measure in humans. Here we studied circadian behaviour in transgenic HD sheep expressing the […]

Influence of time of food administration on daily rhythm of total locomotor activity in ponies
The activity rhythm can be entrained by nonphotic cues, especially food availability. Daily feeding schedules can act as “Zeitgeber” to synchronize the circadian system. In this study, the authors evaluated the influence of different feeding schedules on the daily rhythm of total locomotor activity in ponies. Six clinically healthy Shetland ponies were kept under natural […]

Daily rhythm of total activity pattern in domestic cats (Felis silvestris catus) maintained in two different housing conditions
Housing conditions and human presence have been shown to have an influence on daily amount of activity in herbivores. Only few studies on the behavior of cats and interactions between cat and human were conducted, and these few works are referred to cats housed in laboratories. At the same way, only few and conflicting reports […]

Toll-Like Receptor Agonists as Antecedent Therapy for Ischemic Brain Injury: Advancing Preclinical Studies to the Nonhuman Primate
Antecedent therapy for ischemic brain injury has the potential to protect a large, high-risk patient population from the devastating effects of cerebral ischemia associated with cardiac surgery. Substantial evidence has shown that preconditioning with a modestly damaging stimulus induces powerful endogenous neuroprotection. Pharmacological agents that stimulate toll-like receptors (TLRs) induce robust neuroprotective effects as preconditioning […]

A novel method for activity monitoring in small non-human primates
Patterns of spontaneous activity are valuable reflections of well-being in animals and humans and, because of this, investigations have frequently incorporated some form of activity monitoring into their studies. It is widely believed that activity monitoring, alongside assessments of general behaviour, should be included in initial CNS safety pharmacology screening. As the number of marmoset […]
