Effects of dietary phosphorus and calcium levels and phytase supplementation on bone metabolism of egg-laying hens
DownloadFall 2018
The importance of this Ph.D. thesis work is to assess the effects of dietary available phosphorus (avP) and calcium (Ca) levels and phytase supplementation in egg-laying hens and broilers. Two trials were conducted to evaluate the effects of marginal, moderate, and severe reduction in dietary avP...

Effects of Root Zone pH, Calcium and Phosphorus Supply on Selected Boreal Forest Plant Species
DownloadSpring 2015
Soil pH is among the major environmental factors affecting plant growth. In the reclaimed areas following open-pit oil sands mining in northeastern Alberta, Canada, the pH of reclaimed soil is commonly higher than 8.0. The optimum range of soil pH for growth and the tolerance of pH extremes...

Eukaryotic cells are characterized by the presence of membrane-bound organelles. Close proximity between organelles has been observed for decades, but only recently we have really started to understand the importance of these contacts for cellular function. These contacts consist of areas of...

Calcium homeostasis is essential and central to a variety of cellular processes from cell life and death pathways to metabolism to muscle contraction. One component that is essential to intracellular calcium regulation is known as the sarco(endo)plasmic reticulum Ca-ATPase, or SERCA. SERCA...

Heterogeneous distribution of pectin epitopes and calcium in different pit types of four angiosperm species
Download2011
Intervessel pits act as safety valves that prevent the spread of xylem embolism. Pectin–calcium crosslinks within the pit membrane have been proposed to affect xylem vulnerability to cavitation. However, as the chemical composition of pit membranes is poorly understood, this hypothesis has not...

Infants and children require a net positive calcium (Ca2+) balance to achieve optimal bone mineral density by early adulthood. Vitamin D is a hormone that increases blood Ca2+ levels by increasing intestinal absorption and renal reabsorption of Ca2+ as well as bone remodelling. In both the kidney...

Mannitol at clinical concentrations activates multiple signaling pathways and induces apoptosis in endothelial cells
Download1998
Vandorpe, D.H., Izumo, S., Malek, A.M., Goss, G.G., Jiang, L., Alper, S.L.
Background and Purpose—Hyperosmotic mannitol therapy is widely used in the clinical setting for acute and subacute reduction in brain edema, to decrease muscle damage in compartment syndrome, and to improve renal perfusion. Though beneficial rheological effects commonly are attributed to...

Maternal Essential Fatty Acid Status During Pregnancy and Postpartum in the Alberta Pregnancy Outcomes and Nutrition (APrON) Study and Infant Outcomes
DownloadSpring 2017
Docosahexaenoic (DHA) and arachidonic (AA) acids are essential fatty acids found in breast milk and are important for the infant’s brain development and cognitive functions such as those that regulate sleep and crying. The overall goal of this research was to use a large maternal infant cohort,...

Microbiological evaluation of egg shell powder and optimization of its preparation technique
Download2007
Serafini, Álvaro B., Prado, Carla M., Fernandes, Daniela C., Naves, Maria M. V.
The research aimed to analyze the microbiological profile of the dust of the chicken eggshell distributed to needy communities, as an alternative source of calcium, as well as optimize the product development technique, targeting efficacy and safety in hygienic-sanitary terms. Sampling was...

Modulation of Spontaneous Neural Network Bursting in Newborn Rat Brain Slices by Extracellular Calcium, Methylxanthines, and Opioids
DownloadFall 2012
Spontaneous neuronal bursting appears to be pivotal for brain maturation. This thesis studied such synchronized neural network oscillations in immature newborn rat hippocampus, cortex, and locus coeruleus. For this, horizontal brain slices were generated for (simultaneous) suction electrode...
