To use the "apparent diffusion coefficient" (Dapp) as a quantitative imaging parameter, well-suited test fluids are essential. In this study, the previously proposed aqueous solutions of polyvinylpyrrolidone (PVP) were examined and temperature calibrations were obtained. For example, at a temperature of 20°C, Dapp ranged from 1.594 (95% CI: 1.593, 1.595) μm2/ms to 0.3326 (95% CI: 0. 3304, 0.334...

Figure 2 Axial MRI images from the oral cavity of patient 9. (a) PD image, (b) T2 STIR image, (c) realigned mean b=0 image, (d) ADCmono map. The red and white arrows in (b) indicate the primary tumor and metastatic nodes, respectively. Figures (e-f) display pixel-by-pixel calculation outcomes for the right node. (e) ADCmono (10 mm/s). (f) Dapp (10 mm/s), (g) Kapp, and (h) chi. Region (n) ADCmon...

In current research, nine basic esters of para-alkoxyphenylcarbamic acid with incorporated 4-(4-fluoro-/3-trifluoromethylphenyl)piperazin-1-yl fragment, 6i-6m and 8f-8i, were screened for their in vitro antimicrobial activity against Candida albicans, Staphylococcus aureus and Escherichia coli, respectively. Taking into account the minimum inhibitory concentration assay (MIC), as the most activ...

Two hybrid materials, (HPhPip)2[Co(NCS)4] (I) and (HPhPip)(NCS)•PhPip (II), were grown using the slow evaporation method. The characterization of both compounds was accomplished by means different analytical techniques such as IR, TGA–DTA, single X-ray diffraction. XRD showed that (II) crystallized into triclinic noncentrosymmetric orthorhombic systems, respectively. In Compound (I), Co(II) ion...

BACKGROUND Injury to the brain can occur from a variety of physical insults and the degree of disability can greatly vary from person to person. It is likely that injury outcome is related to the biomechanical parameters of the traumatic event such as magnitude, direction and speed of the forces acting on the head. NEW METHOD To model variations in the biomechanical injury parameters, a voice...
