Crepuscular Rhythms of EEG Sleep-Wake in a Hystricomorph Rodent, Octodon degus

Journal of Biological Rhythms, 1998
Sleep-wake circadian rhythms are well documented for nocturnal rodents, but little is known about sleep regulation in diurnal or crepuscular rodent species. This study examined the circadian sleep-wake rhythms in Octodon degus by means of electroencephalogram (EEG) analysis.

Urine composition of some hystricomorph rodents confined to metabolism cages.

Comparative Biochemistry and Physiology Part A: Physiology, 1972
Abstract 1. 1. A comparison was made of the composition of urine from six species of hystricomorphs (chinchilla, plains viscacha, degu, cuis, native guinea-pig and domestic guinea-pig) maintained under laboratory conditions. 2. 2. All species produced moderate amounts of hypertonic urine and daily rhythms in water and electrolyte excretion ...

Studies on the endóparasitic fauna of Trinidad mammals. VII. Parasites of hystricomorph rodents.

Canadian Journal of Zoology, 1951
A possible new variety of cestode, Raillietina (R.) demerariensis var. trinitatae, and two new varieties, Trichuris gracilis var. trinitatae and Aspidodera binansata var. agoutiae and a new species of nematode, Helminthoxys urichi are recorded from the agouti and lappe from Trinidad, B.W.I.

Melatonin binding sites in sciurid and hystricomorph rodents: studies on ground squirrels and guinea pigs.

Brain Research, 1994
Little is known about the distribution of binding sites for the pineal hormone melatonin in non-myomorph rodents. We used 2-[125I]iodomelatonin (IMEL) to analyze the distribution, affinity, and specificity of binding sites in the golden-mantled ground squirrel, a sciurid rodent that reportedly lacks IMEL binding sites in the brain. Specific binding was
