Enhanced longevity in tau mutant Syrian hamsters, Mesocricetus auratus.
The single-gene mutation tau in the Syrian hamster shortens the circadian period by about 20% in the homozygous mutant and simultaneously increases the mass-specific metabolic rate by about 20%. Both effects might be expected to lead to a change in longevity. To test such expectations, the life span of male and female hamsters from three genotypes (wild-type, heterozygous, and homozygous tau mu...
متن کاملBeneficial effect of wheat germ oil on pregnancies in female golden hamsters (Mesocricetus auratus, Waterhouse).
IN AN EARLIER REPORT from this laboratory,5 it was shown that although female hamsters from 1 through 25 months were reproductively active and capable of conceiving, during the latter half of this life period the sizes of the litters delivered were markedly reduced. It was further pointed out that in such senescent females, the number of ova released, fertilized, and implanted was not significa...
متن کاملThe maternal behaviour cycle in golden hamsters (Mesocricetus auratus).
Maternal behaviour in golden hamsters has been the subject of several studies (ROWELL 1960, 1961 a, 1961 b; LOTT 1962; NOIROT & RICHARDS 1966; RICHARDS 1966 a, 1966 b). Most of these have investigated the response to the presentation of pups placed outside the nest by the experimenter, analysing the functional relations between test behaviour and such variables as reproductive stage, hormonal s...
متن کاملOrganization of mating behavior in male hamsters (Mesocricetus auratus).
Factor analysis was applied to standard measures of sexual behavior in 73 male hamsters (Mesocricetus auratus) as they interacted with hormone-primed females. The results suggest that 5 factors, or conceptual mechanisms, function in the organization of the behaviors observed in the first 2 copulatory series. Of these, the 3 that relate to the behaviors in the first copulatory series were compar...
متن کاملSocial housing and social isolation: Impact on stress indices and energy balance in male and female Syrian hamsters (Mesocricetus auratus).
Although Syrian hamsters are thought to be naturally solitary, recent evidence from our laboratory demonstrates that hamsters may actually prefer social contact. Hamsters increase their preference for a location associated with an agonistic encounter regardless of whether they have "won" or "lost". It has also been reported that social housing as well as exposure to intermittent social defeat o...
