The Effects Of Oxidative Stress And Age On Human Spermatozoa, Taryn Mcandrew Jan 2008

The Effects Of Oxidative Stress And Age On Human Spermatozoa, Taryn Mcandrew

Theses : Honours

Male infertility is now recognised as a significant factor in couples having difficulty conceiving. The impact of maternal age has long been known as a limiting factor, however recent research indicates that advancing paternal age can also negatively impact on a couple's chances of conception. One of the major contributing causes of male infertility has now been linked to spermatozoa exposure to reactive oxygen species (ROS). Such exposure induces oxidative stress when coupled with reduced total antioxidant capacity (TAC). Measures of both ROS and TAC are used as tests of oxidative stress status (OSS) which are used together to give …


Is Dance Good For The Body Or Not? : An Examination Of Body Awareness And Injury Prevention For Specialised Tertiary Dance Students, Kylie Murray Jan 2008

Is Dance Good For The Body Or Not? : An Examination Of Body Awareness And Injury Prevention For Specialised Tertiary Dance Students, Kylie Murray

Theses : Honours

The purpose of this research paper is to discover more about tertiary dance and the effects that dance has on the body. I will discuss the pressures that dance places on the body, looking specifically at the years during full time study as a tertiary student. I will address dance issues such as common injuries, the reasons these injuries occur, prevention strategies, the effect that dance has on the mind and training conditions generally. Research into tertiary dance education programs, dance injuries, injury prevention, and general dance patterns will be supported by survey responses to come to some conclusions about …


Modulation Of Corticomotor Excitability During Passive And Active Wrist Flexion And Extension, Lilian Min Yen Chye Jan 2008

Modulation Of Corticomotor Excitability During Passive And Active Wrist Flexion And Extension, Lilian Min Yen Chye

Theses : Honours

Various mechanisms may alter corticomotor excitability to agonist and antagonist muscles during passive and active limb movement depending on parameters of movement and their functional role. A better understanding of these relationships is important for understanding basic motor control mechanisms, and may be relevant to motor rehabilitation programs after brain injury. The purpose of the present study was to compare changes in corticomotor excitability to wrist flexor and extensor muscles during different phases of movement (flexion/extension), and at rest and during actively or passively-mediated length changes. Motor evoked potentials (MEP) of the flexor carpi radialis (FCR) and extensor carpi radialis …


The Relationship Between Session Rate Of Perceived Exertion Measures And The Volume Load Of Resistance Training, Mirza Abdul Latif Jan 2008

The Relationship Between Session Rate Of Perceived Exertion Measures And The Volume Load Of Resistance Training, Mirza Abdul Latif

Theses : Honours

The purpose of the study was to investigate the relationship between session rate of perceived exertion (RPE) measures and the volume load (VL) during resistance training (RT). Twelve male and eight female participants (24.3 ± 4.2 years) performed three RT sessions per week for a period of four weeks. The RT sessions during the week consisted of strength, hypertrophy and power protocols that included the same four resistance exercises (bench press, squat, shoulder press and bench row). The participants performed 3 sets of 3 repetitions per exercise at a load of 75-90% of their 1-RM with a rest period of …


Distribution Patterns And Habitat Use Of Black Cockatoos (Calyptorhynchus Spp.) In Modified Landscapes In The South-West Of Western Australia, Marieke S. Weerheim Jan 2008

Distribution Patterns And Habitat Use Of Black Cockatoos (Calyptorhynchus Spp.) In Modified Landscapes In The South-West Of Western Australia, Marieke S. Weerheim

Theses: Doctorates and Masters

Conservation planning for animal species inhabiting modified landscapes requires understanding of where animals occur and how they utilise both natural and modified habitats. In this study the distribution and foraging behaviour of the forest red-tailed cockatoo (Calyptorhynchus banksii naso), Baudin’s cockatoo (C. baudinii) and Carnaby’s cockatoo (C. latirostris) was investigated in three study areas which each contained a different combination of modified habitats. Pickering Brook contained native forest and orchards, Wungong contained a mosaic of native forest and revegetation, while Karnet contained primarily native forest and paddocks. The relationship between cockatoo distribution and land use types was examined by constructing …


Drought Traits Of Eucalyptus Gomphocephala In Yalgorup National Park, Paul L. Drake Jan 2008

Drought Traits Of Eucalyptus Gomphocephala In Yalgorup National Park, Paul L. Drake

Theses: Doctorates and Masters

Isohydric and anisohydric regulation of plant water status has been observed over several decades of field, glasshouse and laboratory studies, yet the functional significance and mechanism of both remain obscure. W e studied the seasonal trends in plant water status and hydraulic properties in a natural stand of Eucalyptus gomphocephala through cycles of varying environmental moisture (rainfall, groundwater depth, evaporative demand ) in order to test for isohydry and to provide physiological information for the mechanistic interpretation of seasonal trends in plant water status. Over a 16-month period of monitoring, spanning two summers, midday leaf water potential correlated with pre-dawn …


The Evaluation Of Midazolam On Head Injured Patients In The Prehospital Setting, Dragana Klinac Jan 2008

The Evaluation Of Midazolam On Head Injured Patients In The Prehospital Setting, Dragana Klinac

Theses: Doctorates and Masters

Midazolam (Hypnovel ®) is the only sedating agent used by paramedics at St John Ambulance Service W.A. in the management of many conditions including seizure activities, antisocial or uncontrollable behaviours, back pain incidents and head injuries. Midazolam, with a rapid absorption, fast onset of action and short duration on neurological activity, has been accepted as a safe and effective agent in prehospital treatment since the late-1990s. Often, if a patient is not complying with treatment or is uncontrollable or aggressive, paramedics are required to sedate the individual. This study primarily examines the use of midazolam for the sedation of unmanageable …
