Overall, these results cast serious doubt on our ability to predict the fate of populations based on short-term measures of micro-evolutionary change.
This enabled us to measure the CVR for micro- and macro-vasculature simultaneously along with NIRS measures of micro-vascular oxy- and deoxy-hemoglobin concentrations.
Subjects underwent detailed cognitive and physical examination, the latter including measures of micro- and macro-vascular disease, glycaemic control, body fat composition and plasma inflammatory markers, cortisol, lipids and liver function tests.
In the present study of patients with type 2 diabetes of at least two years duration and microalbuminuria, renal function was an independent predictor of U-LTE4 even when taking into account anthropometric and biochemical variables as well as measures of micro- and macrovascular endothelial function.
Ki67 positive nuclei were counted as an index of proliferation and CD31 used to determine the number of blood vessels per field for 20 fields per tissue specimen as a measure of micro vessel density (MVD).
Fractional anisotropy (FA), which is derived from DTI, has been shown to reflect functionally relevant micro-structural properties of white matter, including axonal architecture, the extent of myelination and the density of axonal fibers comprising axonal bundles [14] and has therefore been interpreted as a measure of micro-structural integrity [15], [16].
We measured temperature of micro gas sensors using by an IR camera (FLIR T 420, FLIR, USA) to compare with the results of Pt T sensors.
This study extends our knowledge of the detrimental effects of high SBP on brain health in very old adults because it combines extensive, longitudinal measurements of BP and cognition with advanced neuroimaging measures of brain micro- and macrostructure in a well-characterized cohort of very old white and black adults.
Even though many researchers have measured the temperatures of micro gas sensors by IR cameras, there are some still problems in terms of measurement errors by setting the incorrect emissivity and not enough precision due to the resolution of the cameras [8].
We show Macro measures in Table 2 and observe similar trends in terms of micro measures.
