Aims and objectives To examine the quality safety of nurse practitioner services two newly implemented models care at a correctional facility. Background Nurse practitioners could help to meet physical mental health needs Australia's growing prison population; however, role has not previously been evaluated in this context. Design A assurance study conducted an Australian where primary were incorporated into existing healthcare service. The was guided by Donabedian's structure, processes...
Males of most anuran species (frogs and toads) vocalize to attract mates. However, individuals many vocal may also adopt alternative noncalling "satellite" tactics. Satellite males characteristically remain in close proximity calling conspecifics attempt intercept incoming females attracted advertising males. Emerson proposed that alternation between behavior anurans is mediated by a reciprocal interaction circulating levels corticosterone androgens driven depletion energy reserves during...
The intervals between acoustic elements are important in audition. Although neurons have been recorded that show interval tuning, the underlying mechanisms unclear. anuran auditory system is well suited for addressing this problem. One class of midbrain anurans responds selectively over a narrow range pulse-repetition rates (PRRs) and only after several sound pulses occurred with “correct” timing. This “interval-counting” process can be reset by single incorrect interval. Here we show, from...
To evaluate the safety of gadoxetic acid disodium (Gd-EOB-DTPA) magnetic resonance imaging (MRI) and its efficacy in characterizing liver lesions.Lesion characterization classification using combined (unenhanced Gd-EOB-DTPA-enhanced) MRI were compared with those unenhanced contrast-enhanced spiral computed tomography (CT) on-site clinical off-site blinded evaluations for patients focal lesions.Gadoxetic was well tolerated this study. For evaluation, more lesions correctly characterized than...
Sound duration can play a pivotal role in the reproductive behavior of anuran amphibians. Here, we report first whole-cell recordings from duration-selective neurons torus semicircularis, vivo . We show that most short-pass cells exhibited short-latency inhibition and delayed excitation. The increased with tone burst duration. Hence, for long-duration bursts, overlapped excitation, reducing or eliminating spikes; no postinhibitory rebound was present. Other cells, however, showed only...
Circulating hormone levels can mediate changes in the quality of courtship signals by males and/or mate choice females and may thus play an important role evolution signals. Costs associated with shifts males, for example, could effectively stabilize directional selection on male Alternatively, if affect mates females, then variation among contribute to maintenance variability males' Here, I review what is known regarding effects acoustic produced anuran amphibians. Surprisingly, despite...
The effects of androgens on male-typical traits suggest that variation among males in circulating levels can play a major role sexual selection. We examined whether vocal attractiveness is attributable to differences androgen Great Plains toads (Bufo cognatus). found noncalling "satellite" practicing an alternative mating tactic were more likely associate with producing long calls. However, callers satellites did not have higher than without satellites. Rather, had significantly lower...
Significance Understanding how excitatory and inhibitory inputs are integrated to achieve sensory selectivity is an important, but elusive, goal in neuroscience. Whole-cell recordings vivo have revealed excitation inhibition, the computational mechanisms generally unclear. In inferior colliculus, neurons exist that respond selectively short-duration sounds; mechanistic basis of this has long been debated. We combined whole-cell recordings, vivo, with conductance extraction algorithms focal...
Stereotyped intervals between successive sound pulses characterize the acoustic signals of anurans and other organisms provide critical information to receivers. One class midbrain neuron responds selectively when are repeated at slow rates (long intervals). To examine mechanisms that underlie long-interval selectivity, we made whole cell recordings, in vivo, from neurons anuran inferior colliculus (anuran IC). In most cases, long-pass interval selectivity appeared arise interplay excitation...
The social environment can alter mating tactic expression through modulatory effects on the endocrine system. In anuran amphibians (frogs and toads), males often adopt noncalling tactics in response to increased chorus density, but underlying physiological factors mediating this are poorly understood. Recent models suggest that density-dependent of alternative anurans is associated with a cascade hormonal events: high density expected promote an increase circulating androgen levels elicits...
Abstract Short‐term elevations in circulating stress hormones (glucocorticoids) often mediate reduced investment reproductive behaviour favour of self‐maintenance and survival, but the significance these effects sexual selection communication remain largely unexplored. Here we examine acute response context intra‐ intersexual green treefrog Hyla cinerea . Males this species produce agonistic acoustic signals that stimulate hormone corticosterone ( CORT ) rival males, suggesting a central...
