Australia’s Lily Brayton: Performer and theatre artist

Recognition is the aim of this account of an artist who is now remembered largely for her beauty, her wide iconic fame achieved by mass distribution of her image via photography and postcards, and her professional association with a internationally prominent producer who was also her husband. It is however a historically situated study, confining itself to readings of the kind of theatrical, social and cultural work performed by Brayton's presence in a rapidly-modernising Australia during the period between Federation in 1901 and the first World War, which event marks a disjuncture in the patterns of entertainment and cultural discourse in the new nation. Pre-war Australian theatre and vaudeville managements competed vigorously to secure the most acclaimed artists, seeing it as a kind of service and duty to boost their country's prestige along with their own coffers. Meanwhile, local playwrights and producers promoted a burgeoning repertoire of Australian dramas and films which played alongside the imported products in a complex network of cultural codes and affects.

Development of a semimechanistic model to describe the pharmacokinetics of gentamicin in patients receiving Hemodialysis

The aim of this study was to ascertain the most suitable dosing schedule for gentamicin in patients receiving hemodialysis. We developed a model to describe the concentrationtime course of gentamicin in patients receiving hemodialysis. Using the model, an optimal dosing schedule was evaluated. Various dosing regimens were compared in their ability to achieve maximum concentration (C-max, >= 8 mg/L) and area under the concentration time-curve (AUC >= 70 mg(.)h/L and <= 120 mg(.)h/L per 24 hours). The model was evaluated by comparing model predictions against real data collected retrospectively. Simulations from the model confirmed the benefits of predialysis dosing. The mean optimal dose was 230 mg administered immediately before dialysis. The model was found to have good predictive performance when simulated data were compared to data observed in real patients. In summary, a model was developed that describes gentamicin pharmacokinetics in patients receiving hemodialysis. Predialysis dosing provided a superior pharmacokinetic profile than did postdialysis dosing.

Oscar Asche's Modernisms: Flesh, Colour and Light

The article examines the early 20th century Australian actor, theater director, and writer Oscar Asche and how various aspects of his work are expressive of an aesthetic modernism. His theatrical productions with his wife Lily Brayton are discussed, as well as his solo projects like the highly acclaimed musical "Chu Chin Chow." Asche is described as a "vitalist."

Dosing of gentamicin in patients with end-stage renal disease receiving hemodialysis

The aim of this study was to evaluate dosing schedules of gentamicin in patients with end-stage renal disease and receiving hemodialysis. Forty-six patients were recruited who received gentamicin while on hemodialysis. Each patient provided approximately 4 blood samples at various times before and after dialysis for analysis of plasma gentamicin concentrations. A population pharmacokinetic model was constructed using NONMEM (version 5). The clearance of gentamicin during dialysis was 4.69 L/h and between dialysis was 0.453 L/h. The clearance between dialysis was best described by residual creatinine clearance (as calculated using the Cockcroft and Gault equation), which probably reflects both lean mass and residual clearance mechanisms. Simulation from the final population model showed that predialysis dosing has a higher probability of achieving target maximum concentration (C-max) concentrations (> 8 mg/L) within acceptable exposure limits (area under the concentration-time curve [AUC] values > 70 and < 120 mg.h/L per 24 hours) than postdialysis dosing.
