Social housing promotes cognitive function through enhancing synaptic plasticity in APP/PS1 mice

Previous studies have shown that loneliness increases the risk of AD (Alzheimer's disease) onset, while active and frequent social housing delays the onset of cognitive impairment. The mechanism of how this occurs remains unclear. In this study, we investigated how...

Loss of control over mild aversive events produces significant helplessness in mice

This article is about the importance of giving mice control over what happens to them. Most of the pathophysiology of depression are still unknown because of its numerous disease states of distinct etiology and pathogenesis. Stressful rodent models have been...

Ultrasound to UltraSee: The use of ultrasound to determine pregnancy in mice

In March 2017 MRC Ares bought an ultrasound machine to assist in determining pregnancy in timed mating mice. Prior to this, visual checks or palpation would be used to confirm pregnancy. There were limitations with these methods as mice generally...

Give us a break!

Literature is replete with studies on stressors to laboratory rodents; knowing the impact research and husbandry interventions, such as routine cage changing, have on rodents' stress levels, physiology and behaviour, we hypothesised that animals recovering in a familiar environment would...

Optimising health & welfare tracking using the Sanger Mouse Database

Health tracking of animals is required legally under the Animals (Scientific Procedures) Act 1986 (ASPA) to prevent pain, avoidable suffering, distress or lasting harm. This is important with Genetically Modified (GM) animals as they are more likely to have unexpected...

Refining mouse re-derivation by using in vitro fertilisation (IVF) with fresh or frozen sperm as opposed to embryos

To attempt to reduce, refine and replace, we have employed a several new approaches to rederive mouse strains. By using in vitro fertilisation (IVF) with fresh or frozen sperm we can reduce the timeframe and number of animals required to...

A comparison of enrichment items for the promotion of natural gnawing behaviour in laboratory mice

Appropriate housing and husbandry, including environmental enrichment, must take the natural habitat, biology and behaviour of each species into consideration. The Guide for the Care and Use of Laboratory Animals (1996) states that the goal should always be to maximise...
