Calcium and Vitamin D Intake During Pregnancy and Postpartum in the Alberta Pregnancy Outcomes and Nutrition (APrON) StudyDownload
Calcium and vitamin D are important in maintaining a healthy pregnancy. Low intake/status has been associated with preeclampsia, preterm delivery, lower birth weight, poor fetal skeletal growth, reduced bone mass, and excessive maternal bone loss. Rarely have these nutrients been examined...
Kidney stones and osteoporosis are prevalent clinical conditions posing a large economic burden to the healthcare system. A common risk factor for both these diseases is hypercalciuria, which is the inappropriate excretion of calcium in urine. Changes in serum calcium levels are detected by the...
Quantitative information on the uptake and distribution of Al at the cellular level is required to understand mechanisms of Al toxicity, but direct measurement of uptake across the plasma membrane has remained elusive. We measured rates of Al transport across membranes in single cells of Chara...
Directed Evolution Approaches for Improved Genetically Encoded Fluorescent Calcium Ion and Voltage IndicatorsDownload
Fluorescent proteins (FP) have revolutionized our imaging technologies and facilitated visualization of biochemical and physiological processes occurring in complex biological systems, which has opened up a new and unprecedented era in cell biology. Although FPs mainly serve as passive...
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...
Effects of dietary phosphorus and calcium levels and phytase supplementation on bone metabolism of egg-laying hensDownload
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...
Heterogeneous distribution of pectin epitopes and calcium in different pit types of four angiosperm speciesDownload
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...
Mannitol at clinical concentrations activates multiple signaling pathways and induces apoptosis in endothelial cellsDownload
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...
