Both mice and rats are proficient breeders, but rats produce more offspring on average. A mouse can produce several hundred offspring in a year, while a rat can potentially have more than 1,000. In general, rats tend not to mind being in the same territory with other rats. Mice, however...
Differences between rats and mice in the immunosuppressive activity of 2-methoxyethanol and 2-methoxyacetic acid - Smialowicz, Riddle, et al. - 1992 () Citation Context ...n addition, repeated exposure to either EGME or MAA results in atrophied testes and impaired spermatogenesis (Foster et al...
House Mice– These little rodents are lightweight and measure about five inches in length. They have grayish-brown fur. Norway Rats– These heavy, bulky rodents are about a foot long on average. The pests have gray coats with pale underbellies. ...
Although Norway rats and house mice do share a common ancestor, both have clear distinctions in how they develop. Norway rats mature at a slower rate than mice – a 21- to 24-day gestation period versus 19 to 20 days for mice. Rats open their eyes after six days and have a full coat...
When it comes right down to it, mice and rats are actually pretty unique from each other - even though they may share a lot in common. If you suspect your home may be playing unwitting host to a nest of rodents, here’s what to keep an eye out for to let you know which kind of...
1. Mice show a sex difference in the excretion of zenarestat similar to that seen in rats, but dogs and humans show no significant sex difference. 2. Female rats and mice, and both sexes of dogs and humans, appear to possess an active secretory mechanism in the renal excretion of zenar...
We also found that male A/J mice have a larger GCL volume in the right hemisphere than the left. Female A/J mice displayed no such laterality. A similar pattern of laterality, favoring the right HF, had been reported previously in male, but not female, rats. In Experiment 2, we ...
We developed a technique in mice to allow for the elevation and measurement of ICP in living, active animals via an infusion system linked to a pressure sensor in the sub-arachnoid space33. With this approach, we previously confirmed that ICP elevation affects the visual pathways, RGCs, and...
In genetically obese mice, obob obese hyperglycaemic1,2 or yellow obese3 syndromes as well as in hypothalamic obesities produced by aurothioglucose in mice4 or stereotaxic lesions in rats5, there is only an enlargement of the adipose cells. The same results are obtained in rats made obese ...
We examined whether sex differences in κ-opioid receptor (KOPR) pharmacology exist in guinea pigs, which are more similar to humans in the expression level and distribution of KOPR in the brain than rats and mice. The KOPR agonist trans-(±)-3,4-dichloro-N-methyl-N-(2-[1-pyrrolidinyl]...
