Abstract Sinojackia xylocarpa Hu is an endangered plant species endemic to China. In this study, we observed the permeability of Sinojackia xylocarpa Hu drupe in the imbibition phase by using magnetic resonance imaging (MRI) dynamics, and obtained the spatial representation of the water distribution in the drupe. At the same time, the structure of the drupe, the permeability of the seed coat and the endosperm were monitored through scanning electron microscopy (SEM), and paraffin section detection (PSD) .

Decellularized porcine kidneys were recellularized with renal epithelial cells by three methods: perfusion through the vasculature under high pressure, perfusion through the ureter under high pressure, or perfusion through the ureter under moderate vacuum. Histology, scanning electron microscopy, confocal microscopy, and magnetic resonance imaging were used to assess vasculature preservation and the distribution of cells throughout the kidneys. Cells were detected in the magnetic resonance imaging by labeling them with iron oxide. Perfusion of cells through the ureter under moderate vacuum (40 mmHg) produced the most uniform distribution of cells throughout the kidneys.

Objective.To evaluate the utility of magnetic resonance imaging (MRI) in systemic sclerosis (SSc)-associated arthropathy.Methods.MRI of the hand was performed in patients presenting with joint pain/swelling in order (1) to determine the frequency of inflammation on MRI, and (2) to compare MRI with radiography.Results.Of 17 patients with SSc, 10 (59%) had inflammatory MRI findings with synovitis (n = 8), erosions (n = 7), joint effusion (n = 7), or tenosynovitis (n = 8). Bone edema was present in 9 patients. Of 7 patients with MRI erosions, only 2 had radiographic erosions.Conclusion.Our study illustrates the usefulness of MRI in the accurate diagnosis and characterization of SSc-associated arthropathy.

BACKGROUND Magnetic resonance imaging (MRI) provides structural characterization of brain lesions, by measuring volume of axial, sagittal and coronal planes through two dimensional slices. The purpose of this study was to characterize and identify the orthogonal imaging planes to detect non tumour lesions of brain through MRI. METHODS This study included 81 patients, both males and females, suspected of brain lesions and underwent MRI for diagnosis. The variations in the volume of the anatomical structures were measured and compared the planes as axial and sagittal, axial and coronal and coronal and sagittal for non-tumour brain lesions. RESULTS The present study revealed the differences in the measurement of volume in nontumour lesions (N = 81) in axial, sagittal and coronal planes. It was found that the volume of axial planes (9.2) is more dominant than the sagittal (9.1) and coronal planes (8.8) in non-tumour lesions. Statistical analysis was done by Statistical Package for Social Sciences (SPSS version 16 software). Two way/Friedman test were used for comparing the three groups. CONCLUSIONS This study concluded that, in most of the brain lesions irrespective of the type of tumours, axial planes helps more in the detection of tumour volume as compared to sagittal and coronal planes for precise diagnosis of brain lesions.
