| the immune tissues of the endangered red-tailed phascogale (phascogale calura). | the lymphoid tissues of the red-tailed phascogale (phascogale calura) were examined using histological and immunohistochemical techniques. the distribution of immune cells in the tissue beds was documented using antibodies to surface markers cd3 and an mhc class ii antigen (equivalent to hla drii). spleen, gut-associated lymphoid tissues (galt), lung, bronchus-associated lymphoid tissue (balt) and liver were examined. the spleen had defined areas of red and white pulp, with follicles containing ... | 2006 | 16533320 |
| cortical cyto- and chemoarchitecture in three small australian marsupial carnivores: sminthopsis macroura, antechinus stuartii and phascogale calura. | the cyto- and chemoarchitecture of the cerebral cortex has been examined in three small (mouse-sized) polyprotodont marsupial carnivores from australia (the stripe-faced dunnart, sminthopsis macroura; the brown antechinus, antechinus stuartii; and the red-tailed phascogale, phascogale calura) in order to compare the cortical topography of these marsupials with that of diprotodontids, didelphids and eutherians. all three species studied had similar cortical cytoarchitecture. the isocortical surfa ... | 2008 | 18946209 |
| identification of the mrna encoding interleukin-6 and its receptor, interleukin-6 receptor α, in five marsupial species. | expressed coding sequences for interleukin-6 (il-6) and interleukin-6 receptor α (il-6r) were examined in five marsupial species. full length expressed coding sequences for il-6 and il-6r were identified and characterized in the gray short-tailed opossum (monodelphis domestica). for il-6, ∼225 bp fragments of the mrna sequence were identified in the red-tailed phascogale (phascogale calura), kultarr (antechinomys laniger), and stripe-faced dunnart (sminthopsis macroura), while ∼563 bp fragments ... | 2016 | 27431929 |
| to bask or not to bask: behavioural thermoregulation in two species of dasyurid, phascogale calura and antechinomys laniger. | torpor is an important physiological process used to reduce body temperature and thus energy needs in mammals and birds. rewarming from torpor can be costly. in some small mammals basking is used to reduce the cost of rewarming from torpor. the use and duration of basking was measured in two native australian marsupials, the red-tailed phascogale (phascogale calura) and kultarr (antechinomys laniger), using a heat rock. animals were observed via video cameras to determine whether they used baski ... | 2015 | 26590457 |
| molecular identification and expression of lyn tyrosine kinase isoforms in marsupials. | lyn is a tyrosine kinase molecule required for modulation of signalling cascades in cell populations including b lymphocytes of the mammalian immune system. we have characterised the coding domain of the marsupial lyn gene of two macropod marsupials; the tammar wallaby (macropus eugenii) and the bridled nailtail wallaby (onychogalea fraenata) and show the co-expression of two lyn isoforms in cells and tissues of these and three other marsupials (brush-tail possum, trichosurus vulpecula; american ... | 2013 | 23522727 |
| antimicrobial activity of red-tailed phascogale (phascogale calura) serum. | antimicrobial substances in serum include circulating complement proteins and acute phase proteins (apps). we identified gene sequences for apps, haptoglobin (hp), c-reactive protein (crp) and serum amyloid a (saa) in marsupial genomes. hp and saa levels were measured in red-tailed phascogale (phascogale calura) sera using commercially available assays. hp levels were higher in males than females, while saa levels suggest the phascogales used in this study were healthy. serum was co-cultured wit ... | 2017 | 28504094 |
| evaluation of reference genes for gene expression in red-tailed phascogale (phascogale calura) liver, lung, small intestine and spleen. | reference genes serve an important role as an endogenous control/standard for data normalisation in gene expression studies. although reference genes have recently been suggested for marsupials, independent analysis of reference genes on different immune tissues is yet to be tested. therefore, an assessment of reference genes is needed for the selection of stable, expressed genes across different marsupial tissues. | 2016 | 27761339 |
| sequences and expression of pathway-specific complement components in developing red-tailed phascogale (phascogale calura). | marsupials are born immunologically premature, relying on cells and molecules in maternal milk for immune protection. both immunoglobulin and complement proteins have been identified in marsupial milk, but the expression of specific complement proteins remains largely unexplored. we report partial cdna sequences for two complement-activating proteins, c3, c1r, cfp and masp2, in liver tissues from red-tailed phascogale (phascogale calura). conservation of functionally relevant motifs were identif ... | 2016 | 27514577 |
| histological development of the immune tissues of a marsupial, the red-tailed phascogale (phascogale calura). | red-tailed phascogale (phascogale calura) pouch young at birth were relatively underdeveloped in comparison with their eutherian counterparts, and the lymphoid tissues of the immune system were found to be histologically immature. the phascogale thymus rapidly developed in the first few days of pouch life and was quickly populated with lymphocytes. by the end of pouch life, involution of the thymus was underway. the bone marrow started to develop in the early stage of pouch life, although adipoc ... | 2016 | 26599205 |
| changes to food intake and nutrition of female red-tailed phascogales (phascogale calura) during late lactation. | reproduction and especially lactation are nutritionally costly for mammals. maternal access to adequate and optimal nutrients is essential for fecundity, survival of offspring, and offspring growth rates. in eutherian species energy requirements during lactation can be heavily dependent on litter size and the body mass of the female. in marsupials litter size does not appear to affect nutritional requirements during lactation; however, studies of marsupial nutritional requirements during lactati ... | 2015 | 26260432 |
| generation of sex ratio biases in the red-tailed phascogale (phascogale calura). | male semelparous dasyurid species are annual breeders that use a promiscuous mating system. these species have shown biases in litter sex ratios and, with females producing more young than they have available teats, this provides an opportunity for the manipulation of the sex ratio at birth. the sex ratio of embryos and pouch young, and the degree of embryonic overproduction, in red-tailed phascogales (phascogale calura) was investigated to gain an understanding of the mechanism by which sex bia ... | 2008 | 18255017 |
| failure of glucocorticoid feedback during breeding in the male red-tailed phascogale phascogale calura (marsupialia: dasyuridae). | an investigation was made into the factors which lead to an elevation in plasma free cortisol concentration during the last weeks of life of males in natural populations of the red-tailed phascogale phascogale calura. the dexamethasone suppression-test was employed to examine the glucocorticoid feedback control of plasma cortisol both before and during the breeding season. in both sexes acth alone or in combination with dexamethasone caused an elevation in the plasma concentration of cortisol, c ... | 1990 | 2173624 |
| stress and mortality in the red-tailed phascogale, phascogale calura (marsupialia: dasyuridae). | an investigation was made of endocrine changes occurring during the life history of phascogale calura, a small, arboreal, squirrel-like insectivorous marsupial. following a 3-week mating period in july each year, all males disappear from the population and it is presumed that they die. during the mating period the plasma cortisol concentration in males increased to a greater extent than did the plasma corticosterone. during this period the plasma concentration of cbg decreased in the males but n ... | 1987 | 3623073 |
