Validation of proton stopping power ratio estimation based on dual energy CT using fresh tissue samples.

This study confirms the advantages of DECT-based SPR estimation although good results were also obtained using SECT for most tissues. PMID: 29057753 [PubMed - as supplied by publisher]

We report a case of invasive mucormycosis in 52 year-old woman. CT-scan and magnetic resonance imaging found a partial right sinus thrombosis associated with homolateral ethmoidal and maxillary sinusitis with submucosal inflammation. Histopathological examination of excised tissue was positive for mucormycosis. Our patient was treated by surgical debridement and a combination of amphotericin B and caspofungin, with a good outcome.

Sornadurai, Binaya Kumar Sahu, Sandip DharaAbstractIn the present work, we established an ex-situ procedure to synthesize Y2Ti2O7 nanopowder using the microwave-hydrothermal technique followed by conventional calcination treatment. This powder is otherwise synthesized by in-situ through a reaction between Y2O3 and Ti in a steel matrix for the production of oxide dispersion strengthened (ODS) steels. The hydrothermal synthesis was involved of chemical reactio...

The films also contain a quantity of water (4 to 22%) depending on the relative humidity during conditioning (from 7% to 90%, respectively). The calorimetric behavior of dispersed eicosane droplets, studied by Differential Scanning Calorimetry, shows a shift in the melting...

Authors: Fishman JE, Kim GJ, Kyeong NY, Goldin JG, Glassberg MK Abstract OBJECTIVE: Our purpose was to compare quantitative CT-derived changes in lung fibrosis with pulmonary function, including DLCO, in human subjects with idiopathic pulmonary fibrosis who received an injection of one of two different intravenous doses of human bone-marrow-derived mesenchymal stem cells. PATIENTS AND METHODS: Two three-subject cohorts from the AETHER trial (Allogeneic Human Cells in subjects with Idiopathic Pulmonary Fibrosis via Intravenous Delivery) underwent high-resolution CT and clinical testing at baseline, 24 weeks, and...

CONCLUSION: Our findings suggest that although MCI subjects showed similar behavioral phenotypes at the time of diagnosis, EF and further progression were associated with different brain regions according to Aβ burden. Clarification of the etiologies and nature of EF impairment in aMCI are critical for disease prognosis and management. PMID: 31538428 [PubMed - in process]

Minary-JolandanAbstractIn situ nanomechanics in scanning electron microscope (SEM) and transmission electron microscope (TEM) has been the gold-standard for direct observation of deformation mechanisms of metals and alloys. The extracted deformation mechanisms complement the process – microstructure – property relationship that is required for the full understanding of the mechanical behavior of these materials. Micro-pillar compression is perhaps the most frequently used met...

The structure is examined by X-ray diffraction and scanning electron microscopy. The compression properties of the CuZr-based metallic glass composites are tested by universal testing machine. The results show that B2 CuZr phases are embedded in glassy matrix. The microstructure is sensitive to processing parameters. The composites samples show high fractur...

This article presents the effects of pineapple leaf (PALF), napier, and hemp fibres as filler on the scratch resistance of epoxy composites. In particular, it explores the effect of these natural fillers on the horizontal load, coefficient of friction (COF), penetration depth, fracture toughness, scratch hardness, brittleness index and scratch observation. The mixing method using magnetic stirrer was used to produce the natural fibre-filled epoxy composites with different wt%, namely, 5, 7.5, and 10 wt%. The test was performed using a CSM Revetest Xpress, which consisted of a cone of the half-apex angle of 60° end...

McMahon, Jurgen Fripp, Margaret J. Wright, Olivier Salvado, Markus BarthAbstractParticipant movement can deleteriously affect MR image quality. Further, for the visualization and segmentation of small anatomical structures, there is a need to improve image quality, specifically signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR), by acquiring multiple anatomical scans consecutively. We aimed to ameliorate movement artefacts and increase SNR in a h...
