Embryonic and fetal morphology in the lowland paca (Cuniculus paca): A precocial hystricomorph rodent

open access: yesTheriogenology, 2017
In mammals, the embryonic and fetal development of a species has evolved to maximize neonatal survival. In this study, we use a sample of 132 embryos/fetuses of wild lowland paca (Cuniculus paca), obtained over a period of 15 years through collaborative methods with local hunters in the Amazon to describe the intrauterine development of external and ...

Molecular Cloning and Sequencing of ζ-Crystallin/Quinone Reductase cDNA from Human Liver

open access: yes, 1993
Zeta-crystallin is an enzyme-crystallin highly expressed in the lens of some hystricomorph rodents and camels. It has been shown to have a novel NADPH:quinone oxidoreductase activity and is present at enzymatic levels in a variety of tissues from various

ULTRASTRUCTURE OF THE HEAD OF CTENOMYS MAULINUS SPERMATOZOON WITH SPECIAL REFERENCE TO THE NUCLEUS

open access: yes, 1982
The spermatozoa of the neotropical hystricomorph rodent C. maulinus [tuco tuco] were examined cytochemically and under the transmission electron microscope. The head is flattened dorsoventrally.

Expression of recombinant ζ-Crystallin in Escherichia coli with the help of GroEL/ES and its purification

open access: yes, 2001
ζ-Crystallin is a taxon-specific crystallin found in the eye lens of guinea pig and other hystricomorph rodents and camelids. It is an NADPH:quinone oxidoreductase and is also present in low amounts in other tissues where it might act as a ...

Digestive physiology, resting metabolism and methane production of captive Indian crested porcupine (Hystrix indica) [PDF]

open access: yes, 2019
Limited physiological measurements exist for the digestive physiology of porcupines. We measured CH4 emission in three captive Indian crested porcupines (Hystrix indica; 16.1 ± 2.7 kg) fed a diet of pelleted lucerne, and measured feed intake ...

A tangled history: patterns of major histocompatibility complex evolution in the African mole-rats (family: Bathyergidae)

open access: yes, 2007
Phylogenetic trees based upon major histocompatibility complex (MHC) gene sequences, particularly those encompassing sites encoding the antigen recognition site, are often discordant with the species tree.

Steroidogenesis during postnatal testicular development of Galea spixii

open access: yes, 2017
The androgen/estrogen balance is essential for normal sexual development and reproduction in mammals. Studies performed herein investigated the potential for estrogen synthesis in cells of the testes of a hystricomorph rodent, Galea spixii.
