Marsupial interhemispheric relation
Journal of Comparative Neurology, 1968AbstractThree different responses recorded from the opossum neocortex following a stimulus to the homotopical point on the contralateral hemisphere were: the interhemispheric early response (IER), the interhemispheric delayed response (IDR), and the rhythmic afterdischarge (RA).

Developmental & Comparative Immunology, 2016
Marsupials are a group of mammals that give birth to immature young lacking mature immune tissues at birth, and are unable to mount their own specific immune defence. Their immune tissues develop in a non-sterile ex-utero environment unlike that of eutherian mammals such as ourselves.

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 2000
Birth is an event that allows the relatively immature marsupial to move from the internal environment of the uterus to the external environment of the pouch. The newborn marsupial passes down from the uterus to the urogenital sinus and then makes its way to the pouch and attaches to the teat at a very early stage of development.

ESTIMATION OF MARSUPIAL RENIN USING MARSUPIAL RENIN-SUBSTRATE
Journal of Endocrinology, 1972SUMMARY Bilateral nephrectomy of an Eastern Grey kangaroo (Macropus giganteus) increased plasma renin-substrate concentration approximately tenfold when compared with intact kangaroos. A preparation made from this plasma had a renin-substrate concentration of 3000 ng/ml. A pH profile of rate of reaction with pig renin had an optimum at pH 5ยท39.

This 2006 book examines the exciting discoveries in the study of marsupials of the last 20 years. These discoveries have led to significant developments in our understanding of this unique group of mammals. The impact of these developments have been such that marsupials are coming to be seen as model organisms in studies of life history evolution ...

Veterinary Clinics of North America: Exotic Animal Practice, 2014
Marsupials comprise an interesting group of mammals, which are increasingly being kept as pets. Few actual feeding trials have been published, although many anecdotal diets have years of usage with good success. Marsupials have dental and digestive tract adaptations that allow them to use specific niches in their environments.

Science, 1968
The infraclass Metatheria has not been reported from deposits predating the mid-Cretaceous. Fossil material just recovered from Albian deposits in northcentral Texas has definite characteristics of the family Didelphidae and is submitted as being from the oldest known marsupials.

Australian Journal of Zoology, 1989
This review includes a list of the chromosome numbers of marsupials and a summary of the main features of chromosome evolution in this group of mammals. Special topics discussed include sex chromosome mosaicism, the size of the marsupial X chromosome, X chromosomes and nucleolar organisers, complex sex chromosome systems, repeated DNA sequences and ...

Abstract Marsupialia is a diverse group comprising 330 living species that occur in North America, South America, and Australasia (1). Metatheria includes marsupials as well as stem fossils that are more closely related to Marsupialia than to Placentialia.
