Anthropometrics

This document summarizes the rationale, equipment, measurement, protocol and data cleaning procedures for each of the anthropometric measures collected at Wave V. It also documents how constructed variables were derived from the anthropometric measures collected in the field. Whenever possible, data collection and methods in Wave V mirrored those of Wave IV to ensure comparability of data between waves. This document is one in a set of Wave V user guides

Synthesis and Luminescence Properties of Core/Shell ZnS:Mn/ZnO Nanoparticles

In this paper the influence of ZnO shell thickness on the luminescence properties of Mn-doped ZnS nanoparticles is studied. Transmission electron microscopy (TEM) images showed that the average diameter of ZnS:Mn nanoparticles is around 14 nm. The formation of ZnO shells on the surface of ZnS:Mn nanoparticles was confirmed by X-ray diffraction (XRD) patterns, high-resolution TEM (HRTEM) images, and X-ray photoelectron spectroscopy (XPS) measurements. A strong increase followed by a gradual decline was observed in the room temperature photoluminescence (PL) spectra with the thickening of the ZnO shell. The photoluminescence excitation (PLE) spectra exhibited a blue shift in ZnO-coated ZnS:Mn nanoparticles compared with the uncoated ones. It is shown that the PL enhancement and the blue shift of optimum excitation wavelength are led by the ZnO-induced surface passivation and compressive stress on the ZnS:Mn cores

Measures of Inflammation and Immune Function

This document summarizes the rationale, equipment, protocol assays, internal quality control, data cleaning, external quality control, and procedures for the measurement and classification of inflammation at the Wave V home exam. Whenever possible, data collection and methods in Wave V mirrored those of Wave IV to ensure comparability of data between waves, although important inter-Wave differences exist and are grey-highlighted herein. This document is one in a set of Wave V user guides. User guides are also available to describe protocols for the following biological measures in Wave V: Anthropometrics, Cardiovascular Measures, Medication Use – Home Exam, Baroreflex Sensitivity & Hemodynamic Recovery, Glucose Homeostasis, Lipids, Renal Function Additional assays were subsequently performed using archived blood samples from Wave V to mirror those measures that will be analyzed in Add Health Wave VI. None of these additional assays were performed during Wave IV. Those user guides include: Hepatic Injury, Neurodegeneratio
