Refining intratracheal administration (2024)

Intratracheal administration is one of the primary methods for introducing substances into the lungs of experimental mice. In order for all lobes of the lungs to be targeted intubation under anesthesia is the ideal method. This procedure has been amended...

Contactless body temperature assessment for signalling humane endpoints in a mouse model of sepsis

Minimising suffering is an ethical and legal requirement in animal research. This is particularly relevant for research on animal models of sepsis and septic shock, which show rapid progression towards severe stages and death. Specific and reliable criteria signalling non-recovery...

Does the regular husbandry handling method affect response to a novel handler (2024)

Aims: Aim 1: Investigate the effects of tube vs tail handing on ease of handling of mice by future experimenters. Aim 2: Investigate the effects of tube vs tail handling on anxiety in mice. Aim 3: Investigate where there are...

Implementing refinement in the EAE mouse model (2025)

Experimental autoimmune encephalomyelitis (EAE) is a model used in rodents to induce inflammation in the central nervous system. It is commonly used as a model for human multiple sclerosis (MS) and other diseases that involve demyelination. EAE has the potential...

Analgesia administration practices to support minimal handling (2024)

An adequate analgesic strategy is important to improve the postoperative recovery and welfare of laboratoy animals. It is desirable that the method for administering the drug is non-invasive and stress-free. Below are a few methods that we use to minimise...

Physiological effects of environmental enrichment on BALB/c and C57BL/6 strain mice (2025)

Our aim was to assess the effects of enriched environment (EE) on some physiological variables, comparing BALB/c and C57BL/6 strain mice. Female BALB/c and C57BL/6 were individually housed under standard laboratory cages for 6 weeks and randomly separated into groups (n = 7...

What are the most prevalent welfare issues for pet small mammals? (2025)

The welfare of pet small mammals is an understudied, but growing research topic in the UK and Europe. We surveyed European veterinary experts who each rated severity and prevalence of a large number of issues in the eight most common...

Phenotypical, behavioral, and systemic hallmarks in end-point mouse scenarios (2025)

The state of frailty is a clinical–biological syndrome that affects the older population with a higher risk of functional dependence. Animal models can provide a tool to study this complex scenario. In the present work, we analyzed the physical and...

The calm mouse: An animal model of stress reduction

Chronic stress is associated with negative health outcomes and is linked with neuroendocrine changes, deleterious effects on innate and adaptive immunity, and central nervous system neuropathology. Although stress management is commonly advocated clinically, there is insufficient mechanistic understanding of how...

Burrowing behavior as robust parameter for early humane endpoint determination in murine models for pancreatic cancer (2025)

Due to late-stage diagnoses and limited treatment options, pancreatic cancer is predicted to be the second leading cause of cancer deaths by 2030. Many different murine models were developed over the past decades to test new therapies for this tumor...
