Mathematical methods and models for radiation carcinogenesis studies [PDF]

open access: yes, 1986
Research on radiation carcinogenesis requires a twofold approach. Studies of primary molecular lesions and subsequent cytogenetic changes are essential, but they cannot at present provide numerical estimates of the risk of small doses of ionizing ...

The Naked Mole-Rat: An Unusual Organism with an Unexpected Latent Potential for Increased Intelligence? [PDF]

open access: yes, 2019
Naked mole-rats are eusocial, hairless mammals that are uniquely adapted to their harsh, low-oxygen subsurface habitat. Although their encephalization quotient, a controversial marker of intelligence, is low, they exhibit many features considered tell ...

Naked mole-rat brown fat thermogenesis is diminished during hypoxia through a rapid decrease in UCP1

open access: yesNature Communications, 2021
Naked mole-rats are hypoxia-tolerant mammals, and during hypoxia their body temperature decreases via unknown mechanisms. Here the authors report that the hypoxia-induced body temperature decrease in naked mole rats occurs through decreased brown adipose

Selective inflammatory pain insensitivity in the African naked mole-rat (Heterocephalus glaber).

open access: yesPLoS Biology, 2008
In all mammals, tissue inflammation leads to pain and behavioral sensitization to thermal and mechanical stimuli called hyperalgesia. We studied pain mechanisms in the African naked mole-rat, an unusual rodent species that lacks pain-related ...

Prolactin is a strong candidate for the regulation of luteal steroidogenesis in vizcachas (Lagostomus maximus) [PDF]

open access: yes, 2018
Prolactin (PRL) is essential for the maintenance of the corpora lutea and the production of progesterone (P4) during gestation of mice and rats, which makes it a key factor for their successful reproduction.

HYBRIDIZATION AND SPECIATION IN FOSSORIAL MOLE RATS [PDF]

open access: yesEvolution, 1976
Hybrid zones between parapatric chromosomal species are of prime evolutionary significance as natural testing grounds for assessing the degree of reproductive isolation between parental species. Major problems of evolutionary dynamics and of species formation may be resolved in hybrid zones.

Biodegradability and tissue reaction of random copolymers of L-leucine, L-aspartic acid, and L-aspartic acid esters [PDF]

open access: yes, 1977
A series of copoly(α-amino acids) with varying percentages of hydrophilic (l-aspartic acid) and hydrophobic monomers (l-leucine, ß-methyl-l-aspartate, and ß-benzyl-l-aspartate) were implanted subcutaneously in rats and the macroscopic degradation ...

Extended longevity of reproductives appears to be common in Fukomys mole-rats (Rodentia, Bathyergidae). [PDF]

open access: yesPLoS ONE, 2011
African mole-rats (Bathyergidae, Rodentia) contain several social, cooperatively breeding species with low extrinsic mortality and unusually high longevity.
