Chronobiology and psychiatry : development of a conceptual model and integrative approach for South African psychiatrists
Chronobiology developed slowly after it was recognised that rhythmicity was a fundamental property of life. However, the principles of chronobiology are not well integrated in clinical practice. Therefore, this dissertation aims to integrate neuroscientific knowledge in a curriculum for …

Motivation as a Common Cognitive Signature of Physical and Mental Health: Bridging Computational Psychiatry, Chronobiology, and Metabolic Health
Motivation plays a fundamental role in human behaviour and shapes the way we engage with the world. But why do individuals differ in their motivational drive and behaviour? The effort-based decision-making framework helps us formalise cognitive mechanisms involved in motivation, furthering our …

A sleep behaviour intervention to improve cardiometabolic health in adults with overweight and obesity
… moved to South Africa where he was introduced to chronobiology in exercise science. In 2013, Rob continued to study in South Africa for his Master of Science (Exercise Science) degree and published his first peer-reviewed article in the Journal of Biological Rhythms. He then developed an interest …

Mahalanobis kernel-based support vector data description for detection of large shifts in mean vector
… using a real data set received from Halberg Chronobiology Center. Compared to Gaussian kernel, Mahalanobis kernel makes SVDD and thus the K chart significantly more sensitive to shifts in mean vector, and also in covariance matrix.

FROM CLOCKS TO EXERCISE, FROM METABOLISM TO PERFORMANCE: A CHRONOPHYSIOLOGICAL APPROACH
… thesis provides a comprehensive introduction to chronobiology, highlighting its role in regulating physiological processes such as sleep-wake cycles, hormonal rhythms, and metabolic functions. The second part examines how chronobiological factors affect physical performance, emphasizing the role …

Chronobiological plasticity in Honeybee and its association with differences in the organization of the molecular pathway between central and peripheral clocks: the brain and flight muscle tissues.
… especially in such an excellent model in chronobiology: the Honeybee.

Role of Aryl Hydrocarbon Receptor in Circadian Rhythm: A Novel Pathway to Dioxin Toxicity
… new perspectives in both dioxin toxicology and chronobiology.

Time series analysis and machine learning studies of biophotovoltaic systems
… inspires new research directions linking chronobiology and bioelectrochemistry. This seminal work is a strong foundation for developing further data-driven models for: (i) pre-modelling experiments and interpreting results; (i) running sensitivity analyses; (iii) hybrid models; and (iv) …

Estradiol exerts activational and organizational control over the expression of daily and circadian activity rhythms in mice
… of the intersection of endocrinology and chronobiology, provide greater insight regarding disease pathogenesis, and provide novel targets for the development of efficacious therapies aimed at circadian disruption prevention and alleviation. Accordingly, I have three primary goals for this …

Investigation of natural and synthetic coupling of the circadian clock in the cyanobacterium Synechococcus elongatus
… clock, is a well-studied model for microbial chronobiology. However, historical tool limitations have left much still to learn about this clock, including definitive answers as to whether it exhibits coupling. During this PhD project, the tool set has been expanded and subsequently applied to …

Daily organisation of cellular physiology by mTOR kinase
Circadian rhythms are self-sustained biological oscillations with a period of approximately 24 hours. They are observed across all levels of biological scale and organise physiology to accommodate the different environmental and energetic demands of day and night. In mammalian cells, the …

Development of fish embryonic stem cell lines as tools for basic and applied studies of interest in aquaculture
… disciplines such as Developmental Biology, Chronobiology and Environmental Physiology. As a prerequisite, these cell lines must be properly established and characterised in order to obtain reliable and reproducible results. However, for reasons of clinical interest these in vitro cellular …

The influence of sleep-wake behaviour and chronotype on the match-play and physical performance of tennis players
Tennis is one of the world's most popular sports, with matches played at various times during the day and night. The match result is the ultimate indicator of successful performance; however, determining a player's performance may not be that straightforward. Chapter two of this thesis explores the …

The role of a circalunar clock in speciation
Once thought impossible, many contemporary studies now suggest that speciation with gene flow is not only possible, but perhaps more common than previously assumed. Phenotypes influencing both mating and ecology (magic traits) lie at the center of many simple models of sympatric speciation and may …

Genetic Circadian Mosaics and the Clock Network’s Contributions to Sleep
<p>Circadian rhythms are physiological and behavioral changes which follow a 24-hour cycle. <em>Drosophila Melanogaster</em>’s circadian clock neuronal network (CCNN) has been identified and several subpopulations have been characterized based on previous studies; the classifications of …

Understanding the dynamics of rhythmic gene expression in mammalian cells
In mammals, circadian rhythms are driven by a cell-autonomous core-clock mechanism consisting of over a dozen core-clock genes forming transcription-translation feedback loops. The core-clock mechanism also drives the rhythmic expression of downstream genes called clock-controlled genes, which are …

Circadian Regulation of Protein Homeostasis
Circadian rhythms orchestrate physiology across all kingdoms of life to anticipate the differing demands of day and night. Circadian timekeeping has a cell-autonomous basis, amenable to study in cultured mammalian cells, where daily rhythms have been shown to affect most biological processes. In …
