We describe a label-free method based on spectral small-angle X-ray scattering with a polychromatic beam for in vivo estimation of brain amyloid burden. Our findings comparing 5XFAD versus wild-type mice correlate well with histology, showing promise for a fast and practical in vivo technique....
Nanostructure-specific X-ray tomography reveals myelin levels, integrity and axon orientations in mouse and human nervous tissue Article Open access 19 May 2021 Scalable mapping of myelin and neuron density in the human brain with micrometer resolution Article Open access 10 January 2022 Ultrafa...
21 The X-ray q-states generated represent a quantum coherent mode of the Roentgen X-ray tube in the soft X-ray region. The energy quanta associated to this type of probe might be found well above the first or second ionization limit of materiality sustaining the processes. Consider a ...

A CT scanner comprises an x-ray window mounted on an x-ray tube, a cooling fluid circulation line, and a cooling fluid return line. A cold-plate is operatively mounted on the x-ray tube around the x-ray window. The cold plate includes an elongated shell and corrugated fins for rapidly...
X-ray crystal structures of COX-1 and COX-2 are known, and there is very little difference in the active sites of these two isozymes. COX-1[206] has an active site isoleucine at position 523 (Ile-523) and COX-2[207] has a valine (Val-523) at that position. Because isoleucine is...
WiRE 5.3 software self-modelling curve resolution (SMCR) and hierarchical cluster analysis (HCA) were used for Raman imaging analysis of tumour margins. The spectra were pre-processed by baseline correction, smoothing, cosmic ray removal, and noise filtering before any further multivariate imaging. ...
The computer system 1000 may further include a video display unit 1010 (e.g., a liquid crystal display (LCD) or a cathode ray tube (CRT)). The computer system 1000 also includes an input device 1012 (e.g., a keyboard), a cursor control device 1014 (e.g., a mouse), a disk ...
FIG. 4 illustrates a micrograph of energy dispersive X-ray (EDX) spectrum of the microbead including the silver nanoparticles in accordance with the embodiment of the present invention; FIG. 5 illustrates graphs of surface-enhanced Raman scattering (SERS) spectroscopic analysis on microbeads including...
