background: ratio of second and fourth digit (2d:4d) is known to be germane in analyzing utero concentrations of testosterone and estrogen in human and other vertebrates. 2d:4d had been linked several traits like athletes’ abilities, reproductive success, risk of cancer and cardiovascular disease (cvd). metabolic syndrome (mets) is a clustering of several cardiovascular risk factors. waist ci...
Perfusion measurements using conventional laser Doppler techniques are affected by the variations in tissue optical properties. Differences in absorption and scattering will induce different path lengths and consequently will alter the probability that a Doppler shift will occur. In this study, the fraction of Doppler shifted photons and the Doppler broadening of a dynamic medium, are measured ...
Several illustrative examples are presented in this tutorial review to demonstrate the utility of 2D correlation spectroscopy, especially in life science applications. A set of IR spectra for a model protein system, which is undergoing complex thermally induced changes in the secondary structures, is analyzed by 2D correlation spectroscopy. The method of constructing 2D correlation maps from te...
conclusions despite the widespread use of 2d lvef and its good agreement with ventriculography, strain analysis seems to be more reliable as a quantitative tool for ventricular assessment. results the lvef values obtained by the two methods of ventriculography and echocardiography were not significantly different. the highest correlation regarding the echocardiographic lvef was obtained in the ...
the ir and nmr spectra were coupled with quantum chemical calculations in dft approach usingthe hybrid b3lyp exchange-correlation functional to confirm the structure of 2-methoxycarbonyl-7-methyl-1,3-thiazino[3,2-b][1,2,4]triazine-4,8-dione 2d.
Comparison of 3D and 2D speckle tracking performed on standard 2D and triplane 2D datasets of normal and pathological left ventricular (LV) wall-motion patterns with a focus on the effect that 3D volume rate (3DVR), image quality and tracking artifacts have on the agreement between 2D and 3D speckle tracking. 37 patients with normal LV function and 18 patients with ischaemic wall-motion abnorma...
Application of generalized two-dimensional (2D) correlation in various analytical fields is explored. 2D correlation is a powerful and versatile technique applicable to spectroscopy, chromatography, and other measurements. Construction of 2D spectra is relatively straightforward, requiring only a series of systematically varying analytical signals, like spectra or chromatograms, induced by an e...
