Possible relationships between episodic memory and 1) brain microstructure assessed by magnetic resonance diffusion tensor imaging (DTI), 2) brain volumes assessed by voxel-based morphometry (VBM) were investigated in uncomplicated, detoxified alcoholics.
The potential functional significance of these microstructural changes suggests that this line of investigation may lead to improved understanding of the origins of common gastrointestinal symptoms and perhaps development of novel treatments.— Shulamit Babitz Frøkjær et al. Altered brain microstructure assessed by diffusion tensor imaging in patients with diabetes and gastrointestinal symptoms.
The effect of cutting parameters on microstructure is assessed by varying the cutting speed and cut depth, while keeping the feed rate constant.
The effect of focal bone erosion on bone microstructure was assessed by microCT imaging of either ankle joint or knee joint.
The organization and density of bone collagen were analyzed in vertebrae using second-harmonic generation (SHG) imaging with a two-photon microscope and trabecular bone microstructure was assessed by scanning electron microscope (SEM).
The NW microstructure is then assessed by complementary high-resolution transmission electron microscopy (HR-TEM) and high-resolution X-ray diffraction (HR-XRD) techniques.
At 22 weeks, after sacrifice, microstructure parameters were assessed by micro-computed tomography, and osteoprotegerin (OPG), receptor activator of nuclear factor-κB ligand (RANKL), alkaline phosphatase (ALP) and metalloproteinase 9 (MMproteintexpressionsions were evaluated by Western Blot at subchondral bone.
The film microstructure and properties were assessed by various complementary techniques such as electron probe microanalysis, X-ray diffraction, nanoindentation, ball-on-disc test, and scanning electron microscopy.
Therefore, the aim of our study was to investigate the short-term reproducibility of bone geometry, density, microstructure and biomechanical parameters assessed by HR-pQCT and micro-finite element (μFE) derived analyses, using the cross-sectional area (CSA) registration method in comparison with the use of 3D registration, to find overlapping regions between scans.
The composition and microstructure of the films were assessed by Rutherford backscattering spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, and atomic force microscopy.
The films were characterized by EDS and Raman spectroscopy, hardness was assessed by nanoindentation and microstructure was analysed by OM and SEM.
