Rats aren’t all bad, though. Brown rats are used in laboratories for research. In fact, according to theFoundation for Biomedical Research, 95 percent of all lab animals are mice and rats. A rat’s front teeth grow 4.5 to 5.5 in (11 to 14 cm) each year, according to Discover Magazi...
On the other hand, the scatter fraction was more than 35% for even the smallest size human NEMA-like and XCAT phantoms. These results suggest that sophisticated scatter correction methods may not be required for the indicated sizes of mice and rats.Konik, A.Madsen, M. T.Sunderland, J. J...
Humanized mouse and rat models must be housed in exceptionally protective conditions and may require a special maintenance regimen. Often, mice production is lengthy and, in some cases, restricted by patents. These are the major factors limiting the wider adoption of humanized models across the ...
Skunk pelts (especially striped) were once valuable in thefurindustry but are less so today. Living skunks are more valuable, as most skunks prey primarily on insects, especially those harmful to agriculture. They are also very useful in destroyingratsandmicethat commonly infest farm buildings. Sp...
The spatial orientation of mice and rats in tasks such as the Morris water escape task is guided by extramaze cues. Using data from the control groups of mice used in two drug-finding experiments, we addressed the question whether the size of the Morris water tank affects spatial learning in...

A study in mice kept in standard cages has shown impaired brain development, abnormal repetitive behaviours (stereotypies), and an anxious behavioural profile, all of which can be lessened by making the cage environment more stimulating23. Additionally, cage enrichment (e.g. gnawing objects for ...
On a whole-animal basis, combined analysis of males and females indicated that COT during voluntary wheel running was significantly lower in the S lines(one-tailed P = 0.015). However, mice from S lines are significantly smaller and attain higher maximum speeds on the wheels; with either body...
