Biological rhythms in Aedes aegypti mosquitoes
… and, ultimately, disease transmission. Rhythmic biological processes in mosquitoes help optimize resource exploitation by coordinating behaviors and physiology with fluctuating environmental conditions. Such synchronization enables organisms to adjust their physiology, metabolism, and behavior to …

ECOLOGICAL AND PHYSIOLOGICAL MECHANISMS OF BIOLOGICAL RHYTHMS IN A POLAR-BREEDING SEABIRD
Biological rhythms provide a mechanism for scheduling activity in predictably cyclic environments. During summer above the polar circle, the primary timing cue, the geophysical light-dark cycle, is highly attenuated or absent, yet some animals will exhibit diel rhythms of behavior and physiology …

The role of biological rhythms and blood glucose levels in maintaining a positive mood state.
… to measure fluctuations in mood in relation to biological rhythms, and in response to cognitively demanding situations and simple interventions. Mood was measured throughout the research using the UWIST Mood Adjective Checklist. The most consistent results were in relation to the Energetic …

Steroid Synthesis Patterns in Cultured Fetal and Neo-Natal Hamster Adrenal Glands
The observation of diurnal biological rhythms was first recorded early in the eighteenth century, but it was 200 years before any detailed investigation of the nature of daily plant and animal rhythms was undertaken (Burning, 1964). | As a more virgorous study of biological rhythms developed, it …

A Mutational Analysis of the Period Locus of Drosophila Melanogaster
… is fundamentally involved in the generation of biological rhythms. Three classes of per mutations which alter circadian periodicity have been identified: per<sup>s</sup> mutants have circadian behavioral rhythms of 19h instead of 24h; per mutants have long period rhythms of 28h; and …

Entrainment of Bacterial Synthetic Oscillators using Proteolytic Queueing and Aperiodic Signaling
The bulk of this thesis considers how biological rhythms (oscillators) can be made to synchronize their rhythms by virtue of coupling to an external signal. Such externally controlled synchronization, known as entrainment, is explored using a synthetic biology approach in E.~coli, where I have used …

A sleep behaviour intervention to improve cardiometabolic health in adults with overweight and obesity
… first peer-reviewed article in the Journal of Biological Rhythms. He then developed an interest in sleep and cardiometabolic health, specifically in the context of public health. In 2015, these interests were combined and lead to his current PhD thesis on a sleep behaviour intervention for the …

Productivity in the Workplace for Product Development Teams
… by endogenous and exogenous factors, such as biological rhythms, work style, availability, work interruptions, team size, location, and the management strategies taken in a project. These factors will have an effect on the amount of effective work value generated in a workweek. A mathematical …

FROM CLOCKS TO EXERCISE, FROM METABOLISM TO PERFORMANCE: A CHRONOPHYSIOLOGICAL APPROACH
… processes such as sleep-wake cycles, hormonal rhythms, and metabolic functions. The second part examines how chronobiological factors affect physical performance, emphasizing the role of sleep quality, chronotype, and social jetlag in shaping endurance, strength, and balance. The final section …

Virtual Reality Frontiers in Bipolar Disorders: A Recovery Oriented Cognitive Rehabilitation tool.
… p< 0.030), alexithymia (TAS-20 p<0.007) and in biological rhythms (BRIAN è<0.029). Conclusion: This RCT aims, with regards to it feasibility and design, to inform a confirmatory trial that evaluates the effectiveness of a VR CR program in psychiatric rehabilitation for the treatment of …

The relationship between depression and chronotype: A longitudinal assessment during childhood and adolescence
… the reciprocal interplay between mood and biological rhythms, especially depression and chronotype, during adolescence.

The Role of the Circadian Clock in the Paraventricular Nucleus of the Hypothalamus in Diurnal Energy Balance
<p>Circadian rhythms are internal biological rhythms that drive oscillations in physiology and metabolism. Maintained at the level of individual cells throughout the body, the circadian clock is necessary for driving tissue-specific temporal programs of energy balance. Though loss of the circadian …

The intersection of pain, disease severity, and circadian disruption in experimental autoimmune encephalomyelitis
… area of research in the MS field: circadian rhythms, the 24-hour biological rhythms governing a significant number of functions at the behavioural, systems, cellular, and molecular levels. Evidence suggests that people with MS experience disruption in their circadian rhythms, and that those …

Circadian Secretion of Glucagon-like Peptide-1
Circadian rhythms are 24-hour biological rhythms within organisms that have developed over evolutionary time due to pre-defined environmental changes, mainly the light-dark cycle. Interestingly, metabolic tissues, which have been found to express cell-autonomous clocks that are entrained by food …

Towards an evolutionary perspective of bipolar disorders: Is there a genetic link between bipolar disorders and non-pathological (adaptive) hyperactivity?
… and goal pursuit in contrast to the Biological Rhythms Interview of Assessment in Neuropsychiatry (BRIAN) tool, which measures its pathological characteristics. According to the results regarding the investigated genetic variant (RS1006737) of the CACNA1C gene, an association was …

Relazione gestante-feto, modalità del parto e sviluppo fisico del bambino
… mother and the newborn, the breastfeeding, the biological rhythms achieved from newborns. From the data analysis a sample with a good level of prenatal attachment and of support social and a good capability to mental functioning emerged. An interesting result is that the most of the women have a …

Altered responsiveness to estrogens at estrogen receptor subtype 1 modifies the expression of circadian rhythms and daily activity patterns in mice
Biological rhythms are critical for the timing of hormone secretion, reproduction, and rest-wake activity patterns. Sex differences in daily (circadian) rhythms have been described for a number of species including humans. Women have a higher incidence of sleep disorders than men and are twice as …
