Sequence analyses have revealed the existence of homology between certain aeroallergens and proteolytic enzymes. This can be expressed functionally, but its significance to airway pathophysiology is unknown. Studies with Madin-Darby canine kidney cells tracheal epithelial grown on plastic substrata or matrix proteins suggest that Der p1, a major allergen from house dust mite Dermatophagoides pteronyssinus cysteine proteinase, unfractionated growth medium extract (SGME) which it was purified,...

We know from research across all levels of education that feedback and interactive teaching have the greatest positive effect on students’ achievement. However, in higher education, teachers’ constructive often logistically cannot be delivered time for students to apply future tasks. In this article, we report a study an approach using assignment exemplars provide with before-task ‘feedback’ or feedforward. evaluated effectiveness through questionnaire analysis grades. Our results show while...

Habitat destruction and fragmentation, interactions with introduced species or the relocation of animals to form new populations for conservation purposes may result in a multiplication population bottlenecks. Examples are translocations koalas French Island its derivative Kangaroo population, both established as insurance policies against koala extinction. In terms size, these programs were success stories. However, genetic story could be different. We conducted investigation by using 15...

Knowledge of the determinants reproductive success is essential for understanding adaptive significance particular traits. The present study examined whether behavioural, morphological, physiological or genetic traits were correlated with male dominance and using three semi-free-ranging captive populations (n = 98) eastern grey kangaroo (Macropus giganteus). morphological measured included bodyweight, head, forearm, tail, pes leg length, forearm bicep circumference, testis size. Blood...

This study evaluated the potential of slow-release GnRH agonist (deslorelin) implants to inhibit reproductive function in male tammar wallaby. The specific aim was measure effects graded dosages deslorelin on testes size and plasma LH testosterone concentrations. Adult wallabies were assigned four groups (n = 6 per group) received following treatment: control, placebo implant; low dose, 5 mg deslorelin; medium 10 mg; high 20 mg. All induced acute increases (P < 0.001) concentrations within 2...

The contraceptive and endocrine effects of long-term treatment with implants containing the GnRH agonist deslorelin were investigated in female tammar wallabies ( Macropus eugenii ). Fertility was successfully inhibited for 515 ± 87 days after a 5 mg implant n = 7), while control animals gave birth to their first young 159 47 placebo administration 8). duration contraception highly variable, ranging from 344 761 days. strict reproductive seasonality wallaby maintained once had expired.

In recent years fertility control has been proposed as an ethically acceptable alternative to lethal techniques when managing overabundant kangaroo populations. A promising non-steroidal, non-immunological approach contraception in female kangaroos involves the use of slow-release implants containing gonadotrophin-releasing hormone (GnRH) agonist deslorelin. The practicality using deslorelin a management option is dependant on its effective inhibition reproduction without negative physical...

The common brushtail possum (Trichosurus vulpecula) has well adapted to increasing urbanization, resulting in greater interaction with humans and their domestic pets. Wildlife species urban areas face a higher risk of exposure zoonotic pathogens may be affected by parasites hosted cats (Toxoplasma gondii) or dogs (Neospora caninum), yet it is unknown what extent T. vulpecula are exposed these parasites. Antibodies gondii N. caninum were assayed sera 142 adult possums from the city Sydney,...

The common brushtail possum (Trichosurus vulpecula) has readily adapted to the expanding urban settings of its native Australian environment. This lead conflict with humans due T.�vulpecula?s seemingly bold behaviour in suburbia. Current management strategies encourage people live harmoniously possums. However, despite cooperation many residents, some object this policy and illegally remove T.�vulpecula from their properties. Wildlife managers are seeking alternative options that aim reduce...

The homologies of the turbinals (scroll bones) ethmoid are not well understood, including potential implication for understanding mammalian phylogeny. Here we examine postnatal development this anatomical system in a marsupial mammal because previous work has shown that adult pattern five endoturbinals (ethmoturbinals) and two ectoturbinals (frontoturbinals) is conserved. Furthermore, phylogeny fairly resolved provides solid evolutionary framework examining turbinal homologies. In study,...

Over the past 20 years there have been many changes in management of rectal cancer. Their impact on overall population is not well known.To determine trends and prognosis cancer two French regions.1978 patients with a carcinoma diagnosed between 1978 1993.Time treatment, stage at diagnosis, operative mortality, survival were studied four year basis. A non-conditional logistic regression was performed to obtain an odds ratio for each period adjusted other variables. To estimate independent...

The effect of treatment with slow release implants containing the GnRH agonist, deslorelin, was investigated in female tammar wallabies. Pouch young were removed from 16 wallabies presumed to be carrying quiescent blastocysts. Eight received a 5 mg deslorelin implant and eight placebo implant. Animals caught daily day 25 30 their pouches inspected for newborn urogenital sinus checked copulatory plug.

Summary Peri‐urban Eastern Grey Kangaroo ( Macropus giganteus ) populations can reach very high densities in areas with remnant native vegetation and adequate pasture. This review summarizes the scientific evidence for impacts of these high‐density peri‐urban populations, which predominantly involve threats to human life livelihood (kangaroo–vehicle collisions), on threatened species ecosystems declines health individual kangaroos. The latter two result from an imbalance between kangaroo...

Volunteer wildlife rehabilitators rescue and rehabilitate thousands of native animals every year in Australia. However, there is little known about how exposure to novel stimuli during rehabilitation could affect the physiology wildlife. We investigated this question a species that commonly enters rehabilitation, common brushtail possum (Trichosurus vulpecula). evaluated five enzyme immunoassays (EIA) determine most suitable for measuring faecal glucocorticoid metabolites (FGM) as proxy...
