The effect of mental fatigue on the performance of Australian football specific skills amongst amateur athletes.

Objectives: This study investigated the effects of induced mental fatigue on the performance of Australian football (AF) specific skills amongst amateur AF players.

Design: Randomised cross over trial.

Methods: Twenty-five amateur AF players performed a series of standardised tests from the Australian Football League (AFL) Draft Combine after completing a 30-min Stroop test (mental fatigue condition) or 30-min control condition.

Illicit drug use and fertility treatment: should we be developing a standard operating procedure?

At present, there are no reliable data to identify the number of patients who present for infertility investigations and who are current users of illicit drugs. Therefore, the full extent of this problem remains hidden. Estimates can be made on the basis of population use, although this lacks rigour.

Characterization of novel composite alginate chitosan-carrageenan nanoparticles for encapsulation of BSA as a model drug delivery system.

The objective of this research project was to develop a nanoparticle drug delivery system using the biopolymer chitosan as the base component. The nanoparticles were produced through ionotropic gelation by flush mixing chitosan with counterions carrageenan and alginate. The nanoparticles were generated under a range of conditions to determine the effect of pH, chitosan concentration, carrageenan concentration, and alginate concentration on the nanoparticle characteristics of particle diameter, zeta potential, and particle size distribution.

Encapsulation and controlled release of recombinant human erythropoietin from chitosan-carrageenan nanoparticles.

Novel chitosan-carrageenan nanoparticles were produced through the process of ionotropic gelation for the encapsulation and controlled release of recombinant human erythropoietin (rHu-EPO). The effects of chitosan concentration, chitosan to carrageenan mass ratio and solution pH on the nanoparticle diameter, polydispersity and surface charge were explored through both screening and response surface modeling (RSM) methods. The chitosan-carrageenan nanoparticles created had particle diameters between 200 and 1000 nm, surfaces charges between 40 and 55 mV, and polydispersity between 0.
