Increased fetal endocardial echogenicity mimicking endocardial fibroelastosis following maternal organophosphorus poisoning and its complete regression in utero
Authors: Balakumar Karippaliyil , Misha Kannan , Milind Karippaliyil 
Published: October 2013

AbstractFetal endocardial fibroelastosis (EFE) has been diagnosed by antenatal ultrasonography in the past few years. A typical case of isolated endocardial fibroelastosis is illustrated here, in a fetus of 22 weeks of gestational age exposed to maternal organophosphorus poisoning at 20 weeks. No other structural cardiac or other systemic anomalies were detected in this fetus. The abnormal fetal echocardiographic features mimicking endocardial fibroelastosis completely regressed after 14 weeks and a normal full-term baby was delivered. Postnatal echocardiogram showed normal cardiac parameters. The diagnostic features mimicking EFE following maternal organophosphorus poisoning at 20 weeks of gestational age and the subsequent complete reversal of these changes after 14 weeks of diagnosis are reported for the first time in the literature.

Published: October 2013

AbstractExtrahepatic biliary atresia (EHBA) is an uncommon cause of neonatal jaundice. Antenatal Magnetic Resonance Imaging (MRI) diagnosis of EHBA has not been published to the best of our knowledge till date. EHBA with cystic component is likely to be mistaken for choledochal cyst. A case that was antenatally predicted and postnatally confirmed by surgery and histopathology is being reported. All imaging signs are analyzed herewith. Imaging helps in the prediction of EHBA and also helps in early postnatal surgical referral which in turn improves the results of Kasai′s portoenterostomy.

ObjectiveTo evaluate the causes of bidirectional flow in the vertebral artery detected by Doppler sonography and its differential diagnosis.MethodsTwenty‐nine patients with bidirectional flow in the vertebral artery were retrospectively studied. The vertebral artery parameters, including peak antegrade velocity (PAV), peak reversed velocity (PRV), maximum peak velocity (MPV), peak systolic velocity, resistive index (RI), and diameter, were measured. The MPV was defined as the MPV of bidirectional flow regardless of the velocity of antegrade or retrograde flow. To better predict the cause of bidirectional flow, receiver operating characteristic curves were constructed for these parameters, and the best cutoff values were obtained. The cause of bidirectional flow was determined by angiography.ResultsThe causes of bidirectional flow were classified as the subclavian steal phenomenon (n = 21) and factors unrelated to the steal phenomenon (n = 8, including a hypoplastic vertebral artery [n = 4] and proximal vertebral artery stenosis and occlusion [n = 4]). Significant differences were observed between the steal phenomenon and non–steal phenomenon groups (P< .05) for MPV, PRV, PAV, target vertebral artery diameter, and contralateral RI. To determine the cause of bidirectional flow, areas under the receiver operating characteristic curves for the different parameters were obtained: 0.929 for MPV, 0.881 for PRV, 0.824 for PAV, 0.753 for target vertebral artery diameter, and 0.845 for contralateral RI. The cutoff value for MPV was 26.1 cm/s, and the accuracy was 93% (27 of 29).ConclusionsBidirectional flow in the vertebral artery is not always indicative of the subclavian steal phenomenon. Measurement of hemodynamic parameters in the vertebral artery, such as MPV, can facilitate determination of the cause of bidirectional flow.

Published: October 2013

ObjectivesThe purpose of this study was to investigate the changes in myocardial function in patients after coronary artery bypass graft (CABG) surgery using longitudinal and circumferential strain on speckle‐tracking imaging.MethodsA total of 145 patients who successfully underwent CABG surgery with a left ventricular ejection fraction (LVEF) of 50% or greater were enrolled in this study. Patients were classified into 4 groups based on age: group 1 (33–59 years), group 2 (60–64 years), group 3 (65–69 years), and group 4 (70–79 years). Routine echocardiography and longitudinal and circumferential strain measurements on speckle‐tracking imaging were performed 1 week before and 1, 3, and 6 months after the CABG.ResultsIn all groups, longitudinal strain increased significantly at 3 and 6 months after CABG therapy compared to baseline (P < .05). A significant increase in circumferential strain was found 1 month after the CABG in groups 1, 2, and 3, and a continuous increase in the parameter was observed in all groups 3 months after therapy (P < .05). However, the LVEF, left ventricular end‐diastolic dimension, and stroke volume measured by routine echocardiography were not significantly changed after successful CABG treatment in all groups during 6 months of follow‐up.ConclusionsBased on the results of our study in all age groups, speckle‐tracking imaging parameters are more effective than the LVEF, left ventricular end‐diastolic dimension, and stroke volume for monitoring improvement in myocardial function after CABG surgery.

ObjectivesThe purpose of this study was to retrospectively evaluate the accuracy and safety of sonographically guided transhepatic biopsies of right upper renal and adrenal masses.MethodsTen sonographically guided transhepatic biopsies were performed in 10 patients with 6 right upper renal masses and 4 right adrenal masses that were invisible or inaccessible via an extrahepatic route. The control population comprised 19 sonographically guided extrahepatic biopsies that were performed in 19 patients with 18 right upper renal masses and 1 right adrenal mass. Transhepatic and extrahepatic biopsies were compared with respect to the diagnostic and complication rates. The mass sizes, biopsy distances, numbers and lengths of cores, and biopsy durations were also compared.ResultsThe diagnostic rates of transhepatic and extrahepatic biopsies were 90% (9 of 10) and 89% (17 of 19), respectively (P > .999). The complication rates of transhepatic and extrahepatic biopsies were 10% (1 of 10) and 21% (4 of 19; P > .999). None of these biopsies resulted in major complications. The mean mass sizes, biopsy distances, and numbers of cores ± SD for transhepatic and extrahepatic biopsies were 33.0 ± 14.3 and 46.9 ± 18.5 mm, 100.5 ± 17.9 and 76.5 ± 9.9 mm, and 2.7 ± 0.9 and 4.0 ± 0.7, respectively (P = .046, .038, and .001). However, the core lengths and biopsy durations were not significantly different between these biopsies (P = .91 and .077).ConclusionsSonographically guided transhepatic core biopsies appear to be feasible and safe procedures for the histologic diagnosis of right upper renal and adrenal masses that are either invisible or inaccessible via an extrahepatic route.

Published: October 2013

ObjectivesWe hypothesized that sonographically guided core biopsy is an effective method for the differential diagnosis of adnexal masses and evaluated patients who underwent core biopsies in our gynecologic oncology department.MethodsWe reviewed the medical records of 55 patients who underwent sonographically guided core biopsies in our gynecologic oncology department between 2010 and 2013. Patients with suspected ovarian malignancies who were unsuitable for optimal debulking surgery and patients at risk for higher morbidity and mortality because of a poor performance status, suspected nongynecologic tumors, and peritoneal tuberculosis were indicated for sonographically guided biopsy.ResultsThe indications for sonographically guided core biopsy were candidacy for suboptimal cytoreduction (n = 32 [58.2%]), a poor performance status (n = 11 [20.0%]), and suspected nongynecologic tumors (n = 12 [21.8%]). Histopathologic evaluations revealed primary ovarian tumors in 36 patients (65.5%). Tuberculosis was found to be the second most common disease (n = 8 [14.5%]) among the patients who underwent core biopsies. In 2 patients (3.6%), histologic examination revealed metastatic colorectal cancer.ConclusionsSonographically guided core biopsy may be preferred as a minimally invasive procedure for managing adnexal masses, particularly in patients with advanced ovarian cancer and high comorbidities who might benefit from neoadjuvant chemotherapy and in cases of suspected nongynecologic tumors, including pelvic tuberculosis.
Manipulating Gene Expression in Projection‐Specific Neuronal Populations Using Combinatorial Viral Approaches
Authors: Gore Bryan B. , Soden Marta E. , Zweifel Larry S. 
Published: October 2013

AbstractThe mammalian brain contains tremendous structural and genetic complexity that is vital for its function. The elucidation of gene expression profiles in the brain, coupled with the development of large‐scale connectivity maps and emerging viral vector–based approaches for target‐selective gene manipulation, now allows for detailed dissection of gene‐circuit interfaces. This protocol details how to perform combinatorial viral injections to manipulate gene expression in subsets of neurons interconnecting two brain regions. This method uses stereotaxic injection of a retrograde transducing CAV2‐Cre virus into one brain region, combined with injection of a locally transducing Cre‐dependent AAV virus into another brain region. This technique is widely applicable to the genetic dissection of neural circuitry, as it enables selective expression of candidate genes, dominant‐negatives, fluorescent reporters, or genetic tools within heterogeneous populations of neurons, based upon their projection targets.

In Situ Data Compression Algorithm for Detailed Numerical Simulation of Liquid Metal Filtration through Regularly Structured Porous Media
Authors: Lehmann Henry , Werzner Eric , Mendes Miguel A. A. , Trimis Dimosthenis , Jung Bernhard , Ray Subhashis 
Published: October 2013

AbstractFiltration of metal melts is a common practice used in order to produce materials that meet high requirements with respect to strength and toughness. Numerical simulations of the filtration process not only help to investigate the involved mechanisms but can also contribute to process optimization. Owing to the presence of a wide range of spatial and temporal scales which have to be resolved, these simulations are generally carried out on extremely refined computational grids with high temporal resolution using massively parallelized computation. However, the amount of data resulting from such computations can easily exceed dozens of terabytes, which imposes a severe hindrance on the storage, visualization, and analysis of the solutions. A promising approach for addressing this problem is in situ data compression, where data is already compressed during the simulation run on the supercomputer rather than as a post‐processing step. In this article, a detailed numerical simulation is described for the liquid metal flow through a foam‐like filter structure using the lattice Boltzmann method. A novel in situ data compression procedure is investigated that, while lossy, can achieve arbitrary precision to meet an error bound specified by the user. The efficiency and accuracy of the algorithm are evaluated by statistical analysis and by comparing the trajectories of tracer particles in uncompressed and compressed flow fields. The results demonstrate that, depending on the desired accuracy, compression rates of as low as 20% of the original data size can be achieved.

Authors: Tiwari Dinesh Chandra , Atri Priyanka , Sharma Rishi 
Published: October 2013

AbstractIn this work, Polypyrrole (PPy), Titanium dioxide nanofiber (TiO2‐nf) are prepared by oxidative polymerization and hydrothermal process respectively. The PPy/TiO2‐nf composite is prepared by in situ oxidative polymerization in the presence of pyrrole monomer and TiO2‐nf. The nanocomposite and TiO2‐nf are then characterized by scanning electron microscopy (SEM) and energy dispersive X‐ray spectroscopy (EDX) techniques and XRD studies. Dielectric studies of PPy/TiO2‐nf composite is carried out in the frequency range of 1 KHz‐3 MHz at varying temperature and it shows anomalous behavior at 1MHz, where its value reaches to its minimum value of 13 at room temperature and this dip remains even at higher temperature. Impedance study is used to understand the grain and grain boundary effects of the material; frequency dependent ac conductivity has two regions separated at 1MHz, which is being explained by hopping conduction and Maxwell‐Wagner type mechanism, respectively. © 2013 Wiley Periodicals, Inc.

Published: October 2013

ABSTRACTA simple Schiff‐base colorimetric receptor 1 was prepared. It exhibits an ‘off–on‐type’ mode with high sensitivity in the presence of Hg2+. The change in color is very easily observed by the naked eye in the presence of Hg2+, whereas other metal cations do not induce such a change. A Job plot indicated a 1 : 1 complexation stoichiometry between receptor 1 and Hg2+. The association constant for 1–Hg2+ in Tetrahydrofuran (THF) was determined to be 1.3 × 109 M‐1 using a Hill plot.

Published: October 2013

AbstractPhosphoserine has potential effectiveness as a simple substrate in preparing bone replacement materials, which could enhance bone forming ability. However, there is a need to investigate the independent effect of phosphoserine on osteogenic differentiation of human adipose stem cells (hADSCs). hADSCs were cultured in an osteogenic medium with phosphoserine. Cell proliferation was analysed by CCK8 and osteogenic differentiation was measured by alkaline phosphatase (ALP) activity, von Kossa staining and real time‐polymerase chain reaction (RT‐PCR). No stimulatory effect of phosphoserine on cell proliferation was noted at Days 1, 4 and 7. Deposition of calcium increased after the addition of phosphoserine. mRNA expression of type I collagen (COL‐I), alkaline phosphatase (ALP), osteocalcin (OCN), Osterix, bone morphogenetic protein‐2 (BMP‐2) and RUNX2 increased markedly with phosphoserine treatment. The BMP‐2 antagonist, noggin, and its receptor kinase inhibitors, dorsomorphin and LDN‐193189, attenuated phosphoserine‐promoted ALP activity. BMP‐responsive and Runx2‐responsive reporters were activated by phosphoserine treatment. Thus phosphoserine can promote osteogenic differentiation of hADSCs, probably by activating BMP and Runx2 pathways, which could be a promising approach for enhancing osteogenic capacity of cell‐based construction in bone tissue engineering.
Insights into the Catalytic Performance of Mesoporous H‐ZSM‐5‐Supported Cobalt in Fischer–Tropsch Synthesis

Published: October 2013

AbstractMesoporous H‐ZSM‐5 (mesoH‐ZSM‐5) was used as a carrier for a series of bifunctional Co‐based catalysts for Fischer–Tropsch synthesis with ZrO2 and/or Ru added as promoters. The reducibility of the catalysts was studied in detail by using temperature‐programmed reduction and X‐ray absorption spectroscopy. A comparison of the catalytic performance of Co/mesoH‐ZSM‐5 and Co/SiO2 (a conventional catalyst), after 140 h on stream, reveals that the former is two times more active and three times more selective to the C5–C11 fraction with a large content of unsaturated hydrocarbons, which is next to α‐olefins. The acid‐catalyzed conversion of n‐hexane and 1‐hexene, as model reactions, demonstrates that the improvement in the selectivity toward gasoline range hydrocarbons is due to the acid‐catalyzed reactions of the Fischer–Tropsch α‐olefins over the acidic zeolite. The formation of methane over the zeolite‐supported Co catalysts originates from direct CO hydrogenation and hydrocarbon hydrogenolysis on coordinatively unsaturated Co sites, which are stabilized as a consequence of a strong metal–zeolite interaction. Although the addition of either ZrO2 or Ru increases the catalyst reducibility considerably, it does not affect the product selectivity significantly.
Exploring the Significance of Emotion for Mediation Practice
Authors: Picard Cheryl , Siltanen Janet 
Published: October 2013

AbstractThe authors report on their exploratory study examining the learning process embedded in mediation. Their research procedures involved directed reflexive journaling followed by group discussions to generate insights into how mediation practitioners experience learning in mediation. The significance and role of emotion emerged as central to the dynamic of this learning process. The research indicates that the experience of positive and negative emotions attached to learning needs to be allowed and attended to within the mediation dynamic. This suggests that mediation practitioners need the competence to follow and understand their own learning‐attached emotions as well as those of the parties.
Application of an electronic micropenetrometer to assess mechanical stability of biological soil crusts
Authors: Drahorad Sylvie Laureen , Felix‐Henningsen Peter 
Published: October 2013

AbstractAn in situ determination of biological soil‐crust stability was carried out in two study sites along a sharp rainfall gradient. Penetration resistance (PR) of the crusts was measured using a newly developed light‐weight needle‐type electronic micropenetrometer. The depth‐related PR data revealed two sections possessing different structures and stability. The topcrust (0–2 mm) had significantly higher amounts of N, organic C, carbonates, and salts as compared to the underlain subcrust. The mean PR of the topcrust was 0.68 MPa for the southern study site, Nizzana‐South (≈ 100 mm annual rainfall), and it increased significantly for the northern study site, Nizzana‐69 (≈ 170 mm annual rainfall), with a mean of 1.11 MPa. A subcrust (2–30 mm) was identified that was characterized by a high amount of carbonates and a PR > 2 MPa. The electronic micropenetrometer system is a promising device for identifying areas of changing crust stability in relation to biological soil‐crust properties. The overall stability of biological soil crusts depends on the topcrust and subcrust structure. This structure is linked to abiotic and biotic factors and likely in relation to the amount of annual precipitation.
Surveillance tools and strategies for animal diseases in a shifting climate context
Authors: Salman Mo D. 
Published: October 2013

AbstractAnimal disease surveillance is watching an animal population closely to determine if a specific disease or a group of diseases makes an incursion so that a prior plan of action can be implemented. The purpose of this paper is to review existing tools and techniques for an animal disease-surveillance system that can incorporate the monitoring of climate factors and related data to enhance understanding of disease epidemiology. In recent decades, there has been interest in building information systems by combining various data sources for different purposes. Within the field of animal health, there have only been limited attempts at the integration of surveillance data with relevant climate conditions. Statistical techniques for data integration, however, have been explored and used by several disciplines. Clearly the application of available techniques for linking climate data with surveillance systems should be explored with the aim of facilitating prevention, mitigation, and adaptation responses in the surveillance setting around climate change and animal disease risks. Drawing on this wider body of work, three of the available techniques that can be utilized in the analysis of surveillance data with the available climate data sets are reviewed.
