A validated smartphone-based electrocardiogram reveals severe bradyarrhythmias during immobilizing restraint in mice of both sexes and four strains

Mouse handling and restraint affect behavior, physiology, and animal welfare, yet little information is available on how various mouse restraint methods affect cardiovascular parameters. We validated the use of a smartphone-based ECG sys- tem in mice by performing simultaneous smartphone...

Effects of daytime blue-enriched LED light on physiologic parameters of three common mouse strains maintained on an IVC system

Light has been a crucial part of everyday life since the beginning of time. Most recently, light-emitting diode (LED) light enriched in the blue-appearing portion of the visible spectrum (465 to 485 nm), which is more efficient in energy use,...

Effects of oxygen supplementation on injectable and inhalant anesthesia in C57BL/6 mice

Oxygen supplementation is rarely considered when anesthetizing laboratory mice, despite reports that mice become profoundly hypoxic under anesthesia. Little is known about the effects of hypoxia on anesthetic performance. This article focuses on the effects of oxygen supplementation on physiologic...

Effects of analgesics on tumor growth in mouse models of prostate cancer bone metastasis

Murine models of tumor development often require invasive procedures for tumor implantation, potentially causing pain or distress. However, analgesics are often withheld during implantation because of concerns that they may adversely affect tumor development. Previous studies examining the effects of...

The development of a non-invasive behavioral model of thermal heat stress in laboratory mice (Mus musculus)

Background: Many behavioral and physiological studies of laboratory mice employ invasive methods such as radio telemetry to measure key aspects of behavior and physiology. Radio telemetry requires surgical implants, which may impact mouse health and behavior, and thus reduce the...

The 9 to 5 Rodent − Time for Change? Scientific and animal welfare implications of circadian and light effects on laboratory mice and rats

Rodents, particularly rats and mice, are the most commonly used laboratory animals and are extensively used in neuroscience research, including as translational models for human disorders. It is common practice to carry out scientific procedures on rats and mice during...

An inhalation anaesthesia approach for neonatal mice allowing streamlined stereotactic injection in the brain

Background: Investigating brain function requires tools and techniques to visualise, modify and manipulate neuronal tissue. One powerful and popular method is intracerebral injection of customised viruses, allowing expression of exogenous transgenes. This technique is a standard procedure for adult mice,...

Comparison of sublingual, facial and retro-bulbar blood sampling in mice in relation to animal welfare and blood quality

Introduction: Repeated blood sampling is a common procedure in laboratory mice, but at present it is unknown which technique has the least impact on the animals when large or repeated blood samples are required. Retro-bulbar sinus puncture is a reliable...
