Calcium Intake Patterns In Association With Demographic And Socioeconomic Factors In Us Population 2-69 Years Of Age: A Cross-Sectional Study, Farah Raoof

Public Health Theses

Background: Calcium is important to various aspects of health and is necessary for life. Inadequate calcium intake has serious consequence on health, such as osteoporosis, impaired muscle and nerve functions and obesity. Similarly, excessive intake is associated with cardiovascular risks and urinary tract stone formation. Therefore a balanced calcium intake is of utmost importance especially knowing that maximum calcium storage potential in bones is reached roughly in late 20s of age and starts gradually declining thereafter.

Objective: The objective of this study is to explore calcium intake patterns in the United States population in association with a number of selected …

Roles Of Neurotransmitters In The Regulation Of Neuronal Electrical Properties And Growth Cone Motility, Lei Zhong

Biology Dissertations

In addition to acting in synaptic transmission, neurotransmitters have been shown to play roles in the development of nervous system. Developing neurons extend neurites to connect to their target cells, and growth cones at the tip of growing neurites are critical for pathfinding. Although evidence for the regulation of axonal growth and growth cone guidance by neurotransmitters and neuromodulators is emerging, less is known about the mechanisms by which neurotransmitters affect developing neurons. Here, I focus on three neurotransmitters/ neuromodulators and describe their actions (a) at the level of growth cone, especially on filopodia, which serve as sensors that allow …

The Relationship Between Serum 25-Hydroxyvitamin D, Vitamin D And Calcium Intake, And Adiposity In Infants, Carolyn W. Morris

Nutrition Theses

Purpose: National prevalence of childhood overweight and obesity has plateaued in recent years, but rates remain high, with approximately 10% among children“high weight.” The relationship between adiposity and serum 25-hydroxyvitamin D [25(OH)D] status has been well-explored in older individuals, with inconsistent results. Furthermore, previous studies have suggested a relationship between adequate consumption of calcium and vitamin D and healthy weight status in older children and adults. However, in the infant population, there are few studies detailing the interaction between body composition and serum 25(OH)D or intake of calcium and vitamin D. Our study aims were to assess the association between …
