MOLECULAR MECHANISMS OF APPETITE AND ENERGY BALANCE
… dynamics is crucial to the maintenance of energy balance and hypothalamic centers have different susceptibilities to changes in synaptic capacity, making them potential targets to external stressors during the progression to obesity.

Regulation of Energy Balance by Dietary Protein
… However, the effects of dietary protein on energy expenditure and the underlying mechanisms are not well-established. Moreover, the domestic cat has potential to more closely model human obesity and diabetes; however, the role of dietary protein in the secretion of metabolic hormones has not …

Climate sensitivity study with energy balance models
… variations with two-dimensional seasonal energy balance model. This thesis consists of two parts. The first part is a study of the interaction between the seasonal cycle and the small ice cap instability, which is a possible mechanism for the initiation of glaciation in the northern …

Development of mechanistic energy balance models for grassland
… to understand how grasslands partition the energy they receive into heat and vapour fluxes, and soil heat flux which regulates the underlying soil temperatures. The project described in this thesis was aimed at measuring and modelling the energy balance at two contrasting grassland sites, …

The impact of whey protein isolate on energy balance regulation
… did not affect adipose fat weight, but decreased energy intake, weight gain and intestinal length. The functionality of protein sensing lysophosphatidic acid receptor 5 (LPA5) in 3T3-L1 pre-adipocytes was assessed. Over-expression of the receptor in 3T3-L1 pre-adipocytes provided a growth …

Energy balance of a laboratory population of Ostrea Edulis (L)
The energy balance components of a laboratory population of juvenile Ostrea edulis, fed on Tetraselmis seucica at 15°C and 35%, were investigated. The results show that filtration rate is a power function of body size and is dependent on food concentration. The relationship between food …

Impact of time and spatial averages on the energy balance closure
… ground. They are believed to be the cause of the energy balance closure problem at the earth's surface, because their contribution to the turbulent fluxes is missed by a fixed eddy-covariance tower measurement that has a typical averaging time of 30 minutes. In this thesis, data from the …

The role of PYY in regulating energy balance and glucose homeostasis
… the long-term role of PYY in regulating energy balance is unclear. Results presented in this thesis, using PYY-deficient mice (PYY-/-) and PYY transgenic mice (PYYtg) highlight that PYY indeed has an important role in regulating energy balance and glucose homeostasis in vivo. PYY knockout …

Toward Closing the Urban Surface Energy Balance Using Satellite Remote Sensing
The energy exchanges at the Earth’s surface are responsible for many of the processes that govern weather, climate, human health, and energy use. This exchange, commonly known as the surface energy balance (SEB), determines the near-surface thermodynamic state by partitioning the available energy …

Switching circuit energy balance in iLabs on experimental lab server architecture
… Amplifier Lab to educate students about energy dissipation. The first version of this lab, built entirely in LabVIEW, on iLabs' existing Shared Architecture could not support an interactive lightweight client. In response, the Experimental Lab Server Architecture (ELSA) was developed as a …

Characterizing the Hypothalamic Functions of Irx3 and Irx5 in Energy Balance Regulation
… factors of human obesity and key regulators of energy balance, acting in connection with the intronic variants of FTO. Irx3 and Irx5 are expressed in the arcuate nucleus and median eminence (ARC-ME), a hypothalamic site known to control energy homeostasis via distinct cell types, yet the …

The effect of exercise training on energy balance in the laboratory rat
… and spontaneous wheel exercise on metabolizable energy intake, resting oxygen consumption, thermic effect of food and energy expenditure excluding the cost of exercise (the latter calculated from energy balance determinations) was investigated. The two training regimes had different effects on …

Energy Balance, Immune System Function, and Susceptibility to Mastitis in Dairy Cows
… dissertation evaluate the relationship between energy status and immune system function at the whole animal, protein, and genomic levels, as well as via the utilization of a large-scale epidemiological dataset. Our large-scale study indicated the potential use of circulating non-esterified fatty …

Effects of alcohol and ∆9-tetrahydrocannabinol on energy balance and cognitive behaviors
Habitual consumption of energy-dense foods is a notable contributor to the high incidence of obesity and metabolic syndrome worldwide. The extent to which calories from alcohol contribute to overweight and obesity is debatable. ∆9-tetrahydrocannabinol (THC), the main psychoactive constitute of …

Water and energy balance in the Namib sand-dune lizard, Angolosaurus skoogi
… or the need to stay in positive water and energy balance? Alternatively, is activity reduction voluntary and geared towards optimizing growth and storage, possibly in preparation for periods of physiological stress ? The research required to answer these questions forms the basis of this …

A Theoretical Approach To Assessing Annual Energy Balance In Gray Whales (eschrichtius Robustus)
While direct measurements of energetic demands are nearly impossible to collect on large cetaceans, comprehensive bioenergetic models can give insights on such parameters by combining physiological and ecological knowledge. This model was developed to estimate necessary food intake of gray whales, …
