Signal transduction pathways involved in skeletal muscle fibre type regulation
Mature skeletal muscle fibres can be classified as type 1, type Ha, type IIx or type IE[b fibres according to the myosin heavy chain (MIHQ isoform that they express. More broadly, type I fibres are classified are slow fibres and type Ha, IIx and 11b fibres as fast fibres. However, the phenotype of …

Skeletal muscle fibre-type comparison of whole tissue and subcellular membrane phospholipids and fatty acids
… compositions differed between muscle types, and 3) Wm did not accurately reflect the PL FA composition of any isolated subcellular membranes, with each being unique from each other. As such, the relevancy of the trends reported in the literature of the effects of perturbations on Wm …

The adaptive response of humans to exercise: Impact of exercise intensity, fibre-type specific responses and molecular patterns of response
… and mode on aerobic capacity and performance, fibre-type specific adaptations to training, and individual patterns of response across molecular, morphological and genetic factors. Project #1 determined that training intensity, session dose, baseline VO2max and total training volume do not …

Skeletal muscle composition in various breeds of domestic dogs: (A comparative study)
The rising rate of insulin resistance and type 2 diabetes in humans over the past two decades have been linked to increasing rates of obesity, aging and urbanisation. A similar pattern is occurring in domestic animals, specifically cats and dogs. Skeletal muscle is a vital organ in the regulation …

Inactivity and overfeeding related changes in skeletal muscle composition and metabolism in captive felids - are they at risk of developing metabolic syndrome?
… of skeletal muscle insulin-resistance and type II diabetes in human and domestic animal populations. Wild animals are similarly exposed to these risk factors as a result of captivity. This study aimed at describing the skeletal muscle properties of captive lions (Panthera leo) who present …

Effects of altered physical activity on human skeletal muscle sarcoplasmic reticulum calcium regulation
… chronic inactivity and the influence of muscle fibre type. A final study investigated the effects of an immunosuppressive drug on SR function in rat skeletal muscle.

The effect of endurance training on human ammonia metabolism
… between plasma NH3, blood (LA), and muscle fibre type.

The Effect of Post-Injury Exercise Training on Skeletal Muscle Mitochondria
… muscle exists on a continuum of pure and hybrid fibres (I ↔ I/IIa ↔ IIa ↔ IIa/IIx ↔ IIx ↔ IIx/IIb ↔IIb) which can change phenotypes via external stimuli such as chronic exercise training. The various fibre types differ across characteristics such as shortening velocity, fatigue resistance, and …

Selected exercise and skeletal muscle characteristics of African distance runners
… capacity was measured using by titration and fibre type proportions were analysed histochemically. Comparisons between groups were made with the Student's t-test for unpaired data whilst the relationships between variables were analysed using the Pearson's correlation coefficient. The first …

A study of rat skeletal muscle Troponin C isoforms
… of TnC isoforms in rat single muscle fibres. This method, validated using rat skeletal muscle TnC isoforms purified for the first time as part of this study, was used in conjunction with myosin heavy chain (MHC) isoform based fibre-typing and Sr2+ -activation measurements to explore …

Characterization of Optical Coupling and Back-reflection of Few Mode Fibers
… of approximately 10dB were achieved depending on fibre type and proximal face. Suggestions for extensions to further improve the SBCR as well as for applications of this system are discussed.

Na+, K+-ATPase in single skeletal muscle fibres and the effects of ageing, training and inactivity
… level in skeletal muscle (α1-3 and β1-3). The fibre-specific expression, adaptability and roles of each isoform in human skeletal muscle are explored in this thesis. Research utilising muscle biopsies typically uses samples obtained from the vastus lateralis muscle, which in healthy young …

Membrane properties and calcium ion activity in skeletal muscle fibres of the dystrophic mouse
… the presence of a population of regenerating fibres. Twitch and contracture tension development reached mature levels by 4 weeks in normal soleus muscle, but development was prolonged to 10 weeks in EDL, due to the slower development of type II fibres. Contracture tension was markedly smaller …

Structural and contractile alterations in skeletal muscles from the genetically obese (ob/ob) mouse: impairment or adaptation?
… methods and whole muscle and single fibre approaches. The animals were used at an age where there is no evidence of hyperglycemia or hypertension, thereby allowing the study of obesity without the often concurrent syndromes of diabetes and hypertension. The muscles examined included …

The role of myostatin during postnatal myogenesis and sarcopenia
… muscle weights, as a consequence of massive fibre hypertrophy and hyperplasia, and an increased proportion of type IIB fibres. Aging induced oxidative fibre type changes and atrophy in the wild-type muscle while no fibre type switching was observed in the myostatin-null muscle and atrophy was …

Developments in automating the design of fibre-optic cable
The design of optical fibre cables has for many years been a laborious manual task involving geometrical mathematics, a knowledge of materials, and past experience. The objectives of the work were to develop a series of design aids which would both automate the process of physical cable design and …
