The effect of anabolic-androgenic hormones on postprandial triglyceridaemia and lipoprotein profiles in man
No full textIt has been hypothesised that endogenous testosterone and AAS may predispose humans to premature CHD. However, there is no direct evidence to link these hormones with a greater prevalence of premature CHD. The aim of this thesis was to better describe atherosclerotic risk associated with these hormones by clarifying their effect on additional risk factors for premature atherosclerosis. Little is known about the effect of testosterone and AAS on 'atherogenic dyslipidaemia', a phenotype characterised by elevated postprandial triglyceridaemia, small dense LDL and a low HDLC concentration, which confers a high risk of CHD. Accordingly, the magnitude of postprandial triglyceridaemia, LDL and HDL particle size, and LDLC, HDLC and Lp(a) concentration were compared in male (n=9) and female (n=3) bodybuilders after self administration of AAS for 5-6 weeks (ON cycle) and again after a 4-6 week 'washout' period (OFF cycle), and in normal males (T) (n=10) before and during a reversible suppression of endogenous testosterone, induced using a GnRH agonist (triptorelin), and in a control group (C) (n=8). Lipoprotein size was assessed by gradient gel electrophoresis (GGE), lipoprotein concentrations by immuno and enzymatic assay, and postprandial triglyceridaemia by a standardised oral fat tolerance test (65g/m² ). HDLC decreased in male bodybuilders (0.94±0.30 vs 0.70±0.27 mmol/L, p=0.004; x ± SD) and female bodybuilders (1.3±0.5 vs 0.8±0.2 mmol/L) ON cycle. GGE studies suggested that mostly HDL₂ was reduced. There were no significant reductions in LDL particle size ON cycle. Two males had larger LDL species ON cycle. Lp(a) decreased in male bodybuilders (124.7±128.0 to 69.3±73.3 U/L, p=0.008). ON cycle postprandial triglyceride excursion was unchanged in female bodybuilders and reduced (11.6±10.0 vs 7.5±5.4 mmol/L.hr; p=0.027) in male bodybuilders. In the triptorelin study, HDLC was increased in T (1.07±0.18 vs 1.41±0.28 mmol/L, p=0.002) and not in C. GGE studies indicated an increase of HDL₂ in five T subjects and no increase in C. Total cholesterol increased in T (4.77±0.80 vs 5.24±1.04 mmol/L, p=0.039) but not in C. LDL size increased in four T subjects, and not in C. Lp(a) increased in T (277.9±149.l vs 376.5±222.2 U/L, p=0.004), but not in C. Postprandial triglyceridaemia was unchanged in both T and C. The results of these studies did not show any additional atherogenic effects of endogenous testosterone or AAS in humans. Rather, a suppression of Lp(a) may be an antiatherogenic effect of these hormones. A reduced postprandial triglyceridaemia and increased LDL size in individuals who are predisposed to 'atherogenic dyslipidaemia', may be further antiatherogenic effects of AAS use
Youth and Adolescent Athlete Musculoskeletal Health: Dietary and Nutritional Strategies to Optimise Injury Prevention and Support Recovery
No full textBackground: Despite the well-documented benefits of exercise and sports participation, young athletes are particularly vulnerable to musculoskeletal injuries. This is especially true during periods of rapid growth, sports specialisation, and high training loads. While injuries are an inevitable aspect of sports participation, the risk can be minimised by promoting the development of strong, resilient tissues through proper nutrition and injury prevention strategies. Moreover, targeted nutrition strategies can accelerate recovery and rehabilitation, allowing for a quicker return to sports participation. Methods: This narrative review synthesises scientific evidence with practical insights to offer comprehensive dietary recommendations aimed at strengthening tissues and supporting the healing process during recovery and rehabilitation. The selection of all sources cited and synthesised in this narrative review were agreed upon by contributing author consensus, experts in sports nutrition (R.A., H.V., B.D.) and exercise and sports medicine (M.H.). Results: Key topics include factors that contribute to injury susceptibility, general dietary recommendations for growth and development, sports nutrition guidelines, and nutrition considerations during injury and rehabilitation. This review also addresses external factors that may lead to suboptimal nutrition, such as food literacy and eating disorders. Conclusions: By highlighting these factors, this article aims to equip coaches, nutritionists, dietitians, athletic trainers, physical therapists, parents/guardians, sporting organisations, and schools with essential knowledge to implement effective nutritional strategies for injury prevention, recovery, and rehabilitation, ultimately enhancing long-term health and athletic performance

Occupational Science to a Pedagogy of Occupations: An Occupation-Focussed Framework for Learning and Teaching
No full textThe aim of this paper is to set out a pedagogy of occupations, drawn from occupational science research literature and framed into domains related to a learning and teaching framework. The paper contributes to the evolution of the teaching and learning of occupational therapy. In addition, as a pedagogical framework that is deeply connected to the constructs of human health and well-being it will have relevance for others concerned with the well-being of teachers and learners. A practical example of application to a pre-registration occupational therapy curriculum is given for educators and learners to reflect on according to their own practices. Finally, a toolkit is provided in the Appendix by which teaching and learners can examine their curricula as supportive or in opposition to well-being through learning and teaching

PURPOSE: Cannabidiol (CBD) may exert physiological and psychological effects that benefit athletes (e.g. protect against neurological damage; reduce inflammation, anxiety and pain) (McCartney et al. 2020). This pilot study investigated the effects of CBD on physiological responses to exercise to determine its practical utility within the sporting context.
METHODS: On two occasions, nine endurance-trained males (VO2max: 57.4 ± 4.0 mL·min-1·kg-1) ran for 60 mins at a fixed, moderate-intensity (70% VO2max) (RUN 1) before completing an incremental run to exhaustion (RUN 2) on an indoor treadmill (21.4 ± 0.4 °C). Participants received an oral dose of CBD (300 mg) or placebo 1.5 hrs prior to exercise in a randomised, double-blind, crossover design. Respiratory gases were sampled continuously between 24-32, 37-45 and 50-58 mins of submaximal exercise; heart rate (HR), ratings of perceived exertion (RPEs), ratings of pleasure-displeasure, blood glucose (BG) and lactate (BL) concentrations were measured at 20-min intervals. Blood was drawn at baseline, pre- and post-RUN 1, post-RUN 2 and 1 hr post-RUN 2.
RESULTS: CBD tended to increase submaximal oxygen consumption (+24 ± 13 mL·min-1, p = 0.094). No differences in HR, RPE, BG, BL, or respiratory exchange ratio were observed during submaximal exercise (p’s > 0.10); VO2max (CBD: 3987 ± 462; Placebo: 3868 ± 577 mL·min-1; p = 0.121) and time to exhaustion (CBD: 1286 ± 150; Placebo: 1246 ± 197 sec; p = 0.204) were also similar during the incremental run. CBD tended to increase ratings of pleasure at 20- (p = 0.050) and 40-mins (p = 0.065) of submaximal exercise. Serum interleukin (IL)-6, IL-1β, tumor necrosis factor-α, lipopolysaccharide and myoglobin concentrations increased from baseline with exercise (i.e., post-RUN 1, post-RUN 2 and/or 1 hr post-RUN 2, p’s < 0.05); however, the change was too small to reliably evaluate the effect of CBD. Plasma CBD concentrations were 0 ± 0, 3 ± 2, 77 ± 18, 164 ± 35 and 99 ± 26 ng.mL-1 at each respective time point.
CONCLUSIONS: These preliminary findings suggest that CBD has potential to alter physiological responses during exercise. Further research involving a larger participant sample is required to confirm and better understand these effects. McCartney, D. Benson, M. Desbrow, B. Irwin, C. Suraev, A. McGregor, I.

Lessons from CRISPR: Establishing an Ethical Framework for Emerging Neurological Devices
No full textabstract: The avalanche of ongoing bioscience research has resulted in an unprecedented range of opportunities for the creation of new medical diagnostics and therapies. As the potential to develop treatments for the human body expands, the ability to control, modify, and interfere with abstract parts of an individual's self increases. While basic components of the self - such as the mind, consciousness, and personality - can presently only be altered by natural processes and diseases, current and emerging technologies that can cause changes in the self are in development. It is likely that as understanding of the brain and mind increases, scientists and engineers will be develop the ability to alter the mind and consciousness in profound new ways. Such a paradigm shift will be fraught with ethical concerns, and if those concerns are not handled in an appropriate manner, there is significant potential for harm. This potential for causing harm is not without precedent. Genome editing technology is an area of research which deals with an element of the fundamental self. In recent years, advancements in genome editing technology in the form of the CRISPR/Cas9 system have caused alarm and debate within scientific communities concerning the ethicalness of its use and application. Using lessons learned from the ways in which the CRISPR technology has been beneficially used, an ethical framework might be developed in order to guide the development of emerging neurotechnology. Early implementation of a framework such as the one herein proposed could guide research that is already being conducted. There is still time to influence the way that neurological device research is conducted, and it is duty of ethical scientists in this field to understand and correct these problems clearly and quickly so as to prevent harm. An ethical framework that is consistent with current ethical standards and understandings might be created by reviewing the history and development of CRISPR
DYNAMIC TESTING OF INTERNAL COMBUSTION ENGINES
No full textPhDThe automated testing of internal combustion engines is a field
of considerable importance. This thesis describes a novel area in
the form of dynamic testing. The investigation represents an original
approach to the problem with which the author believes he has developed
a new concept in engine testing.
The resulting information, combined with an appreciation of the
latest developments in automation equipment technology, has lead to a
review of the requirements of a generalised engine test system together
with an outline of the way in which it could be implemented.
The automated engine test beds used during the work are described.
The conventional methods of testing internal combustion engines are reviewed
and a generalised approach to automating them proposed. This
then leads to the suggestion of a new method using dynamic testing techniques
specially evolved in the course of the work. On the basis of
this the implementation of a dynamic full-load power curve as a replacement
for its steady state equivalent was pursued.
The second major use of dynamic techniques is for exhaust emission
cycles. Both dynamic (USEPA Smoke Cycle) and steady-state (USEPA 13
Mode Cycle) cycles were performed. In the case of the former, outer
digital loop techniques were used to improve control response.
In performing the above work, use was made of both analog and
digital simulation techniques for development purposes. This work was
also extended by the development of a simulation of a material handling
system to enable the control and optimisation of a production test
facility to be studied. The testing methods associated with automated
fault diagnosis are also analysed.
On the basis of the above work an engine test system task analysis
was generated and this new concept used to plan a microprocessor
based engine test automation scheme
