Studying Socio‐Affective Communication in Rats through Playback of Ultrasonic Vocalizations
Authors: Wöhr Markus , Seffer Dominik , Schwarting Rainer K.W. 
Published: April 2016

AbstractRats are able to produce ultrasonic vocalizations (USVs). Such USVs are an important component of the rat social behavior repertoire and serve distinct communicative functions as socio‐affective signals. Depending on the emotional valence of the situation, juvenile and adult rats utter (1) aversive 22‐kHz USVs conveying an appeasing and/or alarming function; or (2) appetitive 50‐kHz USVs, which act as social contact calls, amongst others. A 50‐kHz USV radial maze playback paradigm that allows assessment of the behavioral responses displayed by the recipients in a highly standardized manner has been developed. In this newly developed paradigm, a rat is exposed individually to playback of natural 50‐kHz USVs and appropriate acoustic control stimuli using an acoustic presentation system for ultrasound. By this means, it has been consistently shown that 50‐kHz USVs lead to social approach behavior in the recipient, supporting the notion that they serve an affiliative function as social contact calls. © 2016 by John Wiley & Sons, Inc.
Sparse‐view statistical iterative head CT image reconstruction via joint regularization
Authors: Shangguan Hong , Liu Yi , Cui Xueying , Bai Yunjiao , Zhang Quan , Gui Zhiguo 
Published: April 2016

ABSTRACTIt is a significant challenge to accurately reconstruct medical computed tomography (CT) images with important details and features. Reconstructed images always suffer from noise and artifact pollution because the acquired projection data may be insufficient or undersampled. In reality, some “isolated noise points” (similar to impulse noise) always exist in low‐dose CT projection measurements. Statistical iterative reconstruction (SIR) methods have shown greater potential to significantly reduce quantum noise but still maintain the image quality of reconstructions than the conventional filtered back‐projection (FBP) reconstruction algorithm. Although the typical total variation‐based SIR algorithms can obtain reconstructed images of relatively good quality, noticeable patchy artifacts are still unavoidable. To address such problems as impulse‐noise pollution and patchy‐artifact pollution, this work, for the first time, proposes a joint regularization constrained SIR algorithm for sparse‐view CT image reconstruction, named “SIR‐JR” for simplicity. The new joint regularization consists of two components: total generalized variation, which could process images with many directional features and yield high‐order smoothness, and the neighborhood median prior, which is a powerful filtering tool for impulse noise. Subsequently, a new alternating iterative algorithm is utilized to solve the objective function. Experiments on different head phantoms show that the obtained reconstruction images are of superior quality and that the presented method is feasible and effective.

ABSTRACTLeksell Gamma Knife is a mini‐invasive technique to obtain a complete destruction of cerebral lesions delivering a single high dose radiation beam. Positron Emission Tomography (PET) imaging is increasingly utilized for radiation treatment planning. Nevertheless, lesion volume delineation in PET datasets is challenging because of the low spatial resolution and high noise level of PET images. Nowadays, the biological target volume (BTV) is manually contoured on PET studies. This procedure is time expensive and operator‐dependent. In this article, a fully automatic algorithm for the BTV delineation based on random walks (RW) on graphs is proposed. The results are compared with the outcomes of the original RW method, 40% thresholding method, region growing method, and fuzzy c‐means clustering method. To validate the effectiveness of the proposed approach in a clinical environment, BTV segmentation on 18 patients with cerebral metastases is performed. Experimental results show that the segmentation algorithm is accurate and has real‐time performance satisfying the physician requirements in a radiotherapy environment.
Can COMT‐inhibitor delay the clinical progression of Parkinson's disease? 2 years follow up pilot study

Published: April 2016

ABSTRACTHyperhomocysteinemia is associated with the severity of human neurodegenerative diseases due to its neuronal and endothelial toxicities, and pretreatment of a catecho‐O‐methyltransferase (COMTI) could block the l‐dopa induced elevation of serum Hcy levels in preclinical study. However, it is unclear whether hyperhomocysteinemia in the patients with Parkinson's disease (PD) is related to clinical progression or not. Therefore, we conducted this 2‐year follow‐up study to evaluate whether or not COMTI has an impact on the progression or severity of PD. Data for 50 PD patients (22 PD patients treated with l‐Dopa and COMTI and 28 PD patients treated with l‐Dopa alone) who were recruited for this study were compared with those of 19 healthy controls. All subjects underwent Tc‐99m HMPAO SPECT and neurological evaluation including cognitive function. Serum homocysteine (Hcy) was measured at baseline and at the 2‐year follow up visit. The result showed serum Hcy levels were greater in the two PD groups than the healthy control group (P = 0.003), suggesting L‐dopa induced hyperhomocysteinemia. However, the comparison between these two PD groups showed no significant differences in serum Hcy level as well as regional cerebral perfusion, cognitive function or motor severity at baseline and at 2 years, indicating that COMTI neither prevented l‐dopa induced hyperhomocysteinemia nor delayed clinical progression. Given limitation of excluding advanced PD with late motor complications, future large‐scale long‐term followup studies are needed to clarify the effects of COMTI.
MR imaging reconstruction using a modified descent‐type alternating direction method

Published: April 2016

ABSTRACTIn the magnetic resonance imaging (MRI) field, total variation (TV) which is the
‐norm of the gradient‐magnitude images (GMI) is widely used as the regularization in the compressive sensing (CS) based reconstruction algorithm. Based on the classic augmented Lagrangian multiplier method, we propose a modified descent‐type alternating direction method (ADM) for solving the TV regularized reconstruction problems in the following sense: an iteration result generated by the ADM is utilized to generate a descent direction; an appropriate step size along this descent direction is identified; and the penalty parameters are updated. The proposed algorithm effectively combines alternating direction technique with the descent‐type method. Extensive results demonstrate that the proposed algorithm, is competitive with, and often outperforms, other state‐of‐the‐art solvers in the field.
Multi‐contrast MR image denoising for parallel imaging using multilayer perceptron
Authors: Kwon Kinam , Kim Dongchan , Park HyunWook 
Published: April 2016

ABSTRACTFor clinical diagnosis in MRI, multiple examinations are commonly performed to acquire various contrast images. This article presents a learning‐based denoising method for parallel imaging to enhance the quality of multi‐contrast images so that the imaging time can be accelerated highly. Multi‐contrast images share structural information and coil geometry. The proposed method adopts the multilayer perceptron (MLP) model to save the sharable and redundant information among the multi‐contrast images. The images are divided into patches, which are used as the input and output of MLP. A geometry factor map is additionally used to provide noise amplification information of the accelerated MR images. Computer simulation demonstrates that the use of multi‐contrast images and geometry factor contributes to the quality of the reconstructed images. The proposed method reconstructs high‐quality images without impairing details from the subsampled intermediate images, and it shows better results than previous denoising methods.

Published: April 2016

PurposeThe AMS800™ device, by far the most frequently implanted artificial urinary sphincter (AUS) worldwide, is considered to be the “gold‐standard” when male incontinence surgical treatment is contemplated. Despite 40 years of experience, it is still a specialized procedure with a number of challenges. Here, we present the recommendations issued from the AUS Consensus Group, regarding indications, management, and follow‐up AMS800™ implantation or revision.Materials and MethodsUnder ICS auspices, an expert panel met on July 10, 2015 in Chicago, IL, USA in an attempt to reach a consensus on diverse issues related to the AMS800™ device. Participants were selected by the two co‐chairs on the basis of their practice in a University hospital and their experience: number of implanted AUSs according to AMS (American Medical System Holdings Inc., Minnetonka, MN) records and/or major published articles. Topics listed were the result of a pre‐meeting email brainstorming by all participants. The co‐chairs distributed topics randomly to all participants, who then had to propose a statement on each topic for approval by the conference after a short evidence‐based presentation, when possible.ResultsA total of 25 urologists were invited to participate, 19 able to attend the conference. The present recommendations, based on the most recent and relevant data available in literature as well as expert opinions, successively address multiple specific and problematic issues associated with the AMS800™ trough a eight‐chapter structure: pre‐operative assessment, pre operative challenges, implantation technique, post‐operative care, trouble‐shooting, outcomes, special populations, and the future of AUSs.ConclusionThese guidelines undoubtedly constitute a reference document, which will help urologists to carefully select patients and apply the most adapted management to implantation, follow‐up and trouble‐shooting of the AMS800™.

Hydrodynamic meshfree method for high‐rate solid dynamics using a Rankine–Hugoniot enhancement in a Riemann‐SCNI framework
Authors: Roth Michael J. , Chen Jiun‐Shyan , Danielson Kent T. , Slawson Thomas R. 
Published: April 2016

SummaryMany challenging engineering and scientific problems involve the response of nonlinear solid materials to high‐rate dynamic loading. Accompanying hydrodynamic effects are crucial, where shock‐driven pressures may dominate material response. In this work, a hydrodynamic meshfree formulation is developed under the Lagrangian reproducing kernel particle method framework. The volumetric stress divergence is enhanced using a Rankine–Hugoniot‐enriched Riemann solution that introduces the essential physics; oscillation control is introduced through appropriate state and field variable approximations that define the Riemann problem initial conditions. Consequently, non‐physical numerical parameters and length scales required in the traditional artificial viscosity technique for shock modeling are avoided here. Several numerical examples are provided to verify the formulation accuracy across a range of shock loading conditions. Copyright © 2016 John Wiley & Sons, Ltd.
Increasing the flexural capacity of RC beams using steel angles and pre‐tensioned stainless steel ribbons
Authors: Colajanni Piero , Recupero Antonino , Spinella Nino 
Published: April 2016

AbstractThis article presents an experimental programme on reinforced concrete beams retrofitted with steel angles and pre‐stressed stainless steel ribbons to increase their flexural strength and ductility. Two different configurations of the steel ribbon were designed, and two companion specimens for each type considered were subjected to a four‐point bending test to facilitate a direct comparison in the analysis of the effectiveness of the retrofitting technique. The influence of longitudinal steel angles and transverse stainless steel ribbons is analysed, and the concrete confinement due to stainless steel ribbons examined. The strengthened beams show remarkable increments in flexural strength and ductility with respect to the as‐built beam. Moreover, a simple cross‐sectional model was adopted to calculate the flexural strength; then sophisticated numerical tools were used to reproduce both the experimental load‐displacement curve and crack pattern for each specimen.
