Using temporal variability to improve spatial mapping with application to satellite data
Authors: Kang Emily L. , Cressie Noel , Shi Tao 
Published: May 2010

AbstractThe National Aeronautics and Space Administration (NASA) has a remote‐sensing program with a large array of satellites whose mission is earth‐system science. To carry out this mission, NASA produces data at various levels; level‐2 data have been calibrated to the satellite's footprint at high temporal resolution, although there is often a lot of missing data. Level‐3 data are produced on a regular latitude—longitude grid over the whole globe at a coarser spatial and temporal resolution (such as a day, a month, or a repeat‐cycle of the satellite), and there are still missing data. This article demonstrates that spatio‐temporal statistical models can be made operational and provide a way to estimate level‐3 values over the whole grid and attach to each value a measure of its uncertainty. Specifically, a hierarchical statistical model is presented that includes a spatio‐temporal random effects (STRE) model as a dynamical component and a temporally independent spatial component for the fine‐scale variation. Optimal spatio‐temporal predictions and their mean squared prediction errors are derived in terms of a fixed‐dimensional Kalman filter. The predictions provide estimates of missing values and filter out unwanted noise. The resulting fixed‐rank filter is scalable, in that it can handle very large data sets. Its functionality relies on estimation of the model's parameters, which is presented in detail. It is demonstrated how both past and current remote‐sensing observations on aerosol optical depth (AOD) can be combined, yielding an optimal statistical predictor of AOD on the log scale along with its prediction standard error.

Temporal proteome profiling of taxol‐induced mitotic arrest and apoptosis
Authors: Bull Vibeke H. , Fargestad Ellen M. , Strozynski Margarita , Thiede Bernd 
Published: May 2010

AbstractTaxol (Paclitaxel) is a mitotic inhibitor widely used in cancer therapy. Temporal proteome profiling was performed to study changes of proteins during the different cellular states of HeLa cells caused by exposure to taxol. The changes of proteins over time could be associated with various cellular processes such as mitotic arrest, an intermediate between mitotic arrest and apoptosis, apoptosis, and late apoptosis. Calumenin, stress‐induced phosphoprotein 1 (STIP1), and translationally controlled tumor protein (TCTP) were assigned to mitotic arrest and selected for further experiments using immunoblotting and subcellular fractionation. Calumenin translocated from membranes to the cytosol during mitotic arrest and late apoptosis, but was significantly reduced in the cytosol during apoptosis. Translocation of STIP1 to the nucleus was observed at apoptosis and to the cytoskeleton at late apoptosis. TCTP increased in the cytosol at mitotic arrest and in membranes at apoptosis. In addition, the quantitative time courses of Bim isoforms revealed differences between BimL and BimS in comparison with BimEL. In summary, temporal proteome profiling of HeLa cells incubated with taxol allowed the assignment of proteins to certain processes and additional experiments with complementary approaches enabled a more comprehensive understanding of spatial changes of selected proteins during mitotic arrest and apoptosis.
Evaluation and suggestions for improvement of seismic design procedures for R/C walls in dual systems
Authors: Kappos Andreas J. , Antoniadis Panagiotis S. 
Published: May 2010

AbstractThis paper aims to shed some further light on the seismic behaviour and design of reinforced concrete (R/C) walls which form part of dual (frame + wall) structures. The significance of post‐elastic dynamic effects is recognized by most seismic codes in the definition of the design action effects on walls, i.e. bending moments and shear forces. However, the resulting envelopes are not always fully satisfactory, particularly in the case of medium‐to‐high‐rise buildings. The relevant provisions of modern seismic codes are first summarized and their limitations discussed. Then an extensive parametric study is presented which involves typical multi‐storey dual systems that include walls with unequal lengths, designed according to the provisions of Eurocode 8 for two different ductility classes (M and H) and two effective peak ground acceleration levels (0.16 and 0.24g). The walls of these structures are also designed according to other methods, such as those used in New Zealand and Greece. The resulting different designs are then assessed by subjecting the structures to a suite of records from strong ground motions, carrying out inelastic time history analysis, and comparing the results with the design action effects. It is found that for (at least) the design earthquake intensity, the first two modes of vibration suffice for describing the seismic response of the walls. The bending moment envelope, as well as the base shear of each wall, is found to be strongly dependent on the second mode effect. As far as the code‐prescribed design action effects are concerned, only the NZ Code was found to be consistently conservative, whereas this was not always the case with EC8. A new method is then proposed which focuses on quantifying in a simple way the second mode effects in the inelastic response of the walls. This procedure seems to work better than the others evaluated herein. Copyright © 2010 John Wiley & Sons, Ltd.
Low‐intensity pulsed ultrasound increases cellular uptake of superparamagnetic iron oxide nanomaterial: Results from human osteosarcoma cell line U2OS

Published: May 2010

AbstractPurpose:To determine whether low‐intensity pulsed ultrasound (LIPUS) is able to facilitate the uptake of a superparamagnetic iron oxide (SPIO) nanomaterial by cells that do not express high endocytosis capacity.Materials and Methods:The human osteosarcoma cell line U2OS and a silica‐coated SPIO functionalized peripherally with amines groups (overall diameter 8 nm) were used in this study. Adherent U2OS cells were labeled with SPIO by incubating with culture media containing the SPIO at 4.5 μg[Fe]/mL. LIPUS with the same parameters as those used in clinical application to accelerate bone fracture healing (1.5 MHz, duty cycle 1:4, spatial‐average temporal‐average intensity 30 mW/cm2) was applied to the cells at the beginning of the labeling process for 0, 0.5, 1, or 3 hours. The total incubation time with SPIO was 12 hours. SPIO labeling efficiency was evaluated with Prussian blue staining and a blueness measurement method, and magnetic resonance imaging (MRI) of cell pellets via measuring areas of SPIO‐induced signal void.Results:Both Prussian blue staining and in vitro MRI demonstrated that LIPUS application increased the SPIO nanomaterial labeling efficiency for U2OS cells in an exposure‐duration‐dependent manner.Conclusion:This study is a “proof of concept” that LIPUS can facilitate the cellular take‐up of SPIO nanomaterial.

Diagnostic value of minimum apparent diffusion coefficient values in prediction of neuroepithelial tumor grading
Authors: Chen Zhiye , Ma Lin , Lou Xin , Zhou Zhenhong 
Published: May 2010

AbstractPurpose:To retrospectively evaluate the diagnostic accuracy of diffusion weighted image (DWI) in the prediction of neuroepithelial tumors grading, and to appraise the apparent diffusion coefficient (ADC) value of neuroepithelial tumors with histologic findings as a reference standard.Materials and Methods:ADC values in 110 patients with pathologically proved neuroepithelial tumors, including 77 astrocytic tumors, 16 oligodendroglial tumors, 11 oligoastrocytic tumors, and 6 ependymal tumors, were investigated retrospectively. The minimum ADC (MinADC) value of tumors was measured postoperatively on ADC maps, avoiding cystic, necrotic, or hemorrhagic components. The Ki‐67 Labeling Index (Ki‐67 LI) was determined by immunohistochemistry. The patients were classified into low (WHO II) and high (WHO III or IV) grade groups. Correlation analysis, Student t‐test, Welch test, receiver operating characteristic (ROC) analysis, and analysis of variance were used for statistical evaluation.Results:There was a negative correlation between MinADC value and Ki‐67 LI (P < 0.001). The mean MinADC value (1.057 × 10−3 mm2/s) of low grade group was higher than that (0.773 × 10−3 mm2/s) of high grade group. The area under the ROC curve (AUC) was 0.809, and the cutoff MinADC value of 0.900 × 10−3 mm2/s for the differentiation between high and low grade neuroepithelial tumors provided the best combination of sensitivity (85.4%) and specificity (71.0%).Conclusion:MinADC value may be a simple and effective optional tool for the prediction of neuroepithelial tumor grading.

Authors: Prados Ferran , Boada Imma , Prats‐Galino Alberto , Martín‐Fernández Josep Antoni , Feixas Miquel , Blasco Gerard , Puig Josep , Pedraza Salvador 
Published: May 2010

AbstractPurpose:To evaluate diffusion anisotropy from diffusion tensor imaging using new measures derived from Hellinger divergences and from compositional data distances.Materials and Methods:New anisotropy measures obtained from the diffusion tensor imaging were measured and compared with classic ones such as fractional anisotropy (FA) and relative anisotropy (RA). The evaluation was done using the three‐phase plot (3P‐plot). The measures were compared with regard to their sensitivity to detect white and gray matter changes on human DTI data acquired from five normal volunteers. For each volunteer, different volumes of interest located in white matter (WM) and gray matter (GM) were considered.Results:The proposed Compositional Kullback‐Leibler (KLA) and the classic FA had a similar behavior, although KLA detected better the transitions between white and gray matter. Moreover, KLA showed a better discrimination in areas with great confluence of fibers.Conclusion:KLA detects better than FA the difference between WM and GM. This leads KLA to be a good measure for segmenting WM from GM. J. Magn. Reson. Imaging 2010;31:1435–1444. © 2010 Wiley‐Liss, Inc.

Published: May 2010

AbstractPurpose:To investigate the feasibility of rice pads for improving nonuniform fat suppression in magnetic resonance imaging (MRI) of the neck, shoulder, and elbow using the chemical shift selective (CHESS) technique.Materials and Methods:CHESS imaging of the neck, shoulder, and elbow was performed on 10 healthy volunteers with and without the use of rice pads. Images were visually assessed by one radiologist and one radiologic technologist using a four‐point scale. Results were compared using Wilcoxon's signed rank sum test.Results:Images with and without rice pads were rated 3.9 and 1.5 for the neck (P = 0.002), 3.85 and 2.5 for the shoulder (P = 0.002), and 3.4 and 2.45 for the elbow (P = 0.004).Conclusion:Fat‐suppressed images obtained using the CHESS technique were significantly improved by rice pads for the neck, shoulder, and elbow, indicating that image deterioration with CHESS caused by magnetic field nonuniformity can be improved by rice pads in all body areas.

Possible pathological basis for false diagnoses of lymph nodes by USPIO‐enhanced MRI in rabbits
Authors: Lei Jing , Xue Hua Dan , Li Zhuo , Li Shuo , Jin Zheng Yu 
Published: May 2010

AbstractPurpose:To determine the cause of misdiagnosis of lymph nodes in ultrasmall superparamagnetic iron oxide (USPIO) enhanced magnetic resonance imaging (MRI) using histological findings in rabbit tumor and inflammatory models.Materials and Methods:Thirty‐six rabbits were randomly divided into inflammatory and tumor groups. MRI of the popliteal fossa was performed before and 24 hours after USPIO administration. Diagnoses of popliteal lymph nodes were evaluated based on dedicated criteria and were compared with histological and electronic microscopic findings.Results:There were 46 inflammatory and 26 metastatic lymph nodes. Sensitivity, specificity, and positive and negative predictive values of the diagnosis of nodal metastasis were 84.6%, 87.0%, 78.6%, and 90.9%, respectively. There were four false‐negatives with subcapsular metastatic foci and six false‐positives with predominant cortex and paracortex hyperplasia. Electron microscopy showed that in inflammatory nodes, cytophagic bubbles contain many USPIO particles, while in metastatic nodes they contained predominantly cellular residues.Conclusion:Diagnosis of lymph node malignancy is largely determined by the location and number of metastatic tumor cells. A profound understanding of the physiological role of macrophages in nodes with tumor burden will contribute to better diagnoses for clinical application. J. Magn. Reson.

Non‐contrast renal artery MRA using an inflow inversion recovery steady state free precession technique (Inhance): Comparison with 3D contrast‐enhanced MRA
Authors: Glockner James F. , Takahashi Naoki , Kawashima Akira , Woodrum David A. , Stanley David W. , Takei Naoyuki , Miyoshi Mitsuharu , Sun Wei 
Published: May 2010

AbstractPurpose:To assess the performance of a three‐dimensional (3D) non‐contrast respiratory‐triggered steady state free precession (SSFP) pulse sequence for detection of renal artery stenosis.Materials and Methods:A total of 64 patients who had non‐contrast MR angiography (NC MRA) and 3D contrast‐enhanced MRA (CE MRA) performed during the same exam and three patients who had NC MRA followed by conventional catheter angiography within one month of the MRI exam were included in this retrospective study. Two blinded readers evaluated NC MRA images for the presence of significant renal artery stenosis and also rated their diagnostic confidence and evaluated the images for artifact. A similar analysis was performed for CE MRA images by two additional blinded readers, and discrepancies were resolved by consensus reading.Results:The 67 patients had 168 main and accessory renal arteries, with significant (>50%) stenosis in 34 arteries on CE MRA or conventional angiography. The two NC MRA readers had sensitivity and specificity for detection of significant stenosis of 94%/82% and 82%/87% respectively on a per renal artery basis.Conclusion:There was good agreement between CE MRA and NC MRA for detection of significant renal artery stenosis. This technique should prove useful in evaluating patients with suspected renovascular hypertension who are unable to undergo CE MRA. J. Magn. Reson. Imaging 2010;31:1411–1418. © 2010 Wiley‐Liss, Inc.
Fast‐spin‐echo imaging of inner fields‐of‐view with 2D‐selective RF excitations
Authors: Finsterbusch Jürgen 
Published: May 2010

AbstractPurpose:To demonstrate the feasibility of two‐dimensional selective radio frequency (2DRF) excitations for fast‐spin‐echo imaging of inner fields‐of‐view (FOVs) in order to shorten acquisitions times, decrease RF energy deposition, and reduce image blurring.Materials and Methods:Fast‐spin‐echo images (in‐plane resolution 1.0 × 1.0 mm2 or 0.5 × 1.0 mm2) of inner FOVs (40 mm, 16 mm oversampling) were obtained in phantoms and healthy volunteers on a 3 T whole‐body MR system using blipped‐planar 2DRF excitations.Results:Positioning the unwanted side excitations in the blind spot between the image section and the slice stack to measure yields minimum 2DRF pulse durations (about 6 msec) that are compatible with typical echo spacings of fast‐spin‐echo acquisitions. For the inner FOVs, the number of echoes and refocusing RF pulses is considerably reduced which compared to a full FOV (182 mm) reduces the RF energy deposition by about a factor of three and shortens the acquisition time, e.g., from 39 seconds to 12 seconds for a turbo factor of 15 or from 900 msec to 280 msec for a single‐shot acquisition, respectively. Furthermore, image blurring occurring for high turbo factors as in single‐shot acquisitions is considerably reduced yielding effectively higher in‐plane resolutions.Conclusion:Inner‐FOV acquisitions using 2DRF excitations may help to shorten acquisitions times, ameliorate image blurring, and reduce specific absorption rate (SAR) limitations of fast‐spin‐echo (FSE) imaging, in particular at higher static magnetic fields.
