Primary Small Bowel GIST Presenting as a Life-Threatening Emergency: A Report of Two Cases

Gastrointestinal stromal tumor (GIST) is a rare stromal neoplasm, which represents the most common mesenchymal tumor of the gastrointestinal tract. It is characterized by indolent clinical symptoms, although it can present as a life-threatening emergency. Herein, we present two cases of primary small bowel GIST treated at our department. A 68-year-old female patient presented to our emergency department with a diffuse abdominal pain of acute onset. Imaging studies revealed a mass at proximal jejunum, with a nearby free air and fluid. At surgery, a mass of 9 cm was found at proximal jejunum, 3 cm distal to the treitz ligament, with perforation on the lateral wall of the mass. En bloc resection was performed. Pathology report was positive for gastrointestinal stromal tumor. A 70-year-old male patient presented to our emergency department with 3 days of dark tarry stool and few hours of hematochezia. Computed tomography angiography revealed a mass at the pelvis, with calcifications, attached to the distal ileum, with intraluminal blush of intravenous iodine. At surgery, a mass of 8 cm at the distal ileum was found. Resection of the mass along with a 20 cm of ileum was completed. Histopathology report was positive for malignant gastrointestinal stromal tumor.
Royal Jelly Modulates Hepatotoxic Effect of Rats Treated with Cisplatin Ashry

Cisplatin (CP) is one of the most active cytotoxic agents in the treatment of cancer and has adverse side effects such as hepatotoxicity and nephrotoxicity. The aim of this study was focused on investigating the possible protective effect of royal jelly (RJ) against oxidative stress caused by CP injury of the liver and inflammatory changes in male albino rats. Twenty four albino rats were divided into four equal groups as follows: control group, cisplatin group : (rats injected i.p. with single dose from cisplatin (CP, 7 mg / kg body weight,), royal jelly RJ group : rats treated for 15 consecutive days by gavage with RJ (300 mg/kg/day/orally), royal jelly-cisplatin group, rats treated with royal jelly orally for 15 consecutive days by gavage (300 mg/kg/day) followed by a single injection i.p. from CP (7 mg / kg body weight). The obtained results revealed that the administration of royal jelly with cisplatin in rats significantly ameliorated the changes occurred in the biochemical parameters {GSH, GPx and CAT were significantly decreased in liver of cisplatin-treated rats and increasing ALT and AST}. The histopathological results showed distinctive pattern of hepatotoxic changes in cisplatin group, while in the royal jelly-cisplatin group the liver tissues showed reductions lesions. In conclusion, royal jelly acts in the liver as a potent scavenger of free radicals to prevent or ameliorates the toxic effects of CP as shown by biochemical and histopathological investigations and might provide substantial protection against cisplatin-induced hepatotoxicity and inflammatory damages.
The ATESP Radio Survey I. Survey Description, Observations and Data Reduction

This paper is the first of a series reporting the results of the Australia Telescope ESO Slice Project (ATESP) radio survey obtained at 1400 MHz with the Australia Telescope Compact Array (ATCA) close to the South Galactic Pole (SGP) over the region covered by the ESO Slice Project (ESP) galaxy redshift survey (). The survey consists of 16 radio mosaics with resolution and uniform sensitivity ( noise level ~79 μ Jy) over an area of sq. degrees. Here we present the design of the survey, we describe the mosaic observing technique which was used to obtain an optimal combination of uniform and high sensitivity over the whole area, and the data reduction: the problems encountered and the solutions adopted.
Debugging knowledge-based applications with a generic toolkit

Knowledge refinement tools assist in the debugging and maintenance of knowledge based systems (KBSs) by attempting to identify and correct faults in the knowledge that account for incorrect problem-solving. Most refinement systems target a single shell and are able to refine only KBSs implemented in this shell. Our KRUSTWorks toolkit is unusual in that it provides refinement facilities that can be applied to a number of different shells, and is designed to be extensible to new shells. The paper outlines the components of the KRUSTWorks toolkit and how it is applied to faulty KBSs. It describes its application to two real aerospace KBSs implemented in CLIPS and POWER-MODEL to demonstrate its flexibility of application.
Lateralised visual processing in domestic cattle herds responding to novel and familiar stimuli

We investigated whether cattle exhibit preferences to monitor challenging and novel stimuli. Experiments were conducted on dairy and beef cattle herds and revealed significant left eye preferences in the cattle for viewing an experimenter walking to repeatedly split the herd through its centre. Visual lateralisation was demonstrated in the preference to use the left monocular field to monitor the experimenter, alone or equipped with a range of novel stimuli. This finding is consistent with left eye preferences found in various species of mammals, birds, and amphibians responding to predators and novel stimuli. A cohort of the familiarised cattle herds was then subjected to additional herd-splitting tests with the same stimuli and demonstrated a reversal of viewing preferences, preferring to monitor the experimenter and stimuli within the right and not left monocular field. This directional shift in viewing preferences is consistent with experience-dependent learning found in lateralised visual processing in other, non-mammalian, species, and to our knowledge is the first of such studies to suggest that such lateralised learning processes also exist in mammals. Together the data support a number of key hypotheses concerning the evolution and conservation of lateralised brain function in vertebrates, and also provide important considerations for livestock handling.
Runtime fault recovery protocol for NoC-based MPSoCs

The design of reliable MPSoCs is mandatory to cope with faults during fabrication or product lifetime. For instance, permanent faults on the interconnect network can stall or crash applications even though the network has alternative fault-free paths to a given destination. This paper presents a novel fault-tolerant communication protocol that takes advantage of the NoC parallelism to provide alternative paths between any source-target pair of processors, even in the presence of multiple faults. At the application layer, the method is seen as a typical MPI-like message passing protocol. At the lower layers, the method consists of a software kernel layer that monitors the regularity of message exchanges between pairs of tasks. If a message is not delivered in a certain time, the software fires a path finding mechanism implemented in hardware, which guarantees complete network reachability. The proposed approach determines new paths quickly, and the costs of extra silicon area and memory usage are small.
Antibacterial Effects of Six Endodontic Sealers

Purpose The objective of this study was to perform an in vitro evaluation of the antibacterial properties of 6 endodontic sealers (Endomethasone C, Argoseal, Bioseal Normal, Acroseal, AH Plus, Sicura Seal). Methods The agar diffusion test (well and paper disc methods) with Enterococcus faecalis, Staphylococcus aureus and Streptococcus mutans was used. For the well method, Petri dishes were inoculated with bacterial suspensions. Each well was completely filled with freshly mixed endodontic sealer. For the paper disc method, sterile paper discs were immersed in freshly mixed sealers and put on agar plates. Diameters of halos formed around the sealers were measured after 24 h and 48 h. Statistical analysis: The effects of well method and of paper disc method were analyzed by 1-way ANOVA. Results Endomethasone C, Argoseal and Bioseal showed the largest inhibition halos for all the tested microorganisms, while Sicura Seal and AH Plus showed low antibacterial effects. Moreover, the comparison of well method and paper disc methods showed significant statistical differences (P<0,01) for all sealers and indicated a dose-dependent antimicrobial effect.
Divergence between WTA and WTP Revisited: Livestock Grazing on Public Range

The research reported here provides further empirical support for the contention that there is a divergence between WTA and WTP. The conclusion is based on results from a 2002 survey of Nevada ranchers that asked about willingness to pay for public forage and WTA compensation to part with grazing rights. WTP and WTA are estimated simultaneously, with the estimators used to demonstrate a statistically significant divergence between WTP and WTA. The simultaneous estimation allows us to identify ranch characteristics that influence the discrepancy in valuations. Ranch size, public grazing allotment, financial distress, and long term commitment to ranching are all significant influences on the disparity. We interpret these results both with respect to general differences in welfare measures and with respect to ranch policy.
Process mining multiple repositories for software defect resolution from control and organizational perspective

Issue reporting and resolution is a software engineering process supported by tools such as Issue Tracking System (ITS), Peer Code Review (PCR) system and Version Control System (VCS). Several open source software projects such as Google Chromium and Android follow process in which a defect or feature enhancement request is reported to an issue tracker followed by source-code change or patch review and patch commit using a version control system. We present an application of process mining three software repositories (ITS, PCR and VCS) from control flow and organizational perspective for effective process management. ITS, PCR and VCS are not explicitly linked so we implement regular expression based heuristics to integrate data from three repositories for Google Chromium project. We define activities such as bug reporting, bug fixing, bug verification, patch submission, patch review, and source code commit and create an event log of the bug resolution process. The extracted event log contains audit trail data such as caseID, timestamp, activity name and performer. We discover runtime process model for bug resolution process spanning three repositories using process mining tool, Disco, and conduct process performance and efficiency analysis. We identify bottlenecks, define and detect basic and composite anti-patterns. In addition to control flow analysis, we mine event log to perform organizational analysis and discover metrics such as handover of work, subcontracting, joint cases and joint activities.
Big Text Data Clustering using Class Labels and Semantic Feature Based on Hadoop of Cloud Computing

Clustering of class labels can be generated automatically, which is much lower quality than labels specified by human. If the class labels for clustering are provided, the clustering is more effective. In classic document clustering based on vector model, documents appear terms frequency without considering the semantic information of each document. The property of vector model may be incorrectly classified documents into different clusters when documents of same cluster lack the shared terms. To overcome this problem are applied by the knowledge based approaches. However, these approaches have an influence of inherent structure of documents on clustering and a cost problem of constructing ontology. In addition, the methods are limited to cluster suitable text document clustering from in exploding big text data on Cloud environment. In this paper, we propose a big text document clustering method using terms of class label and semantic feature based Hadoop. Class label term can well represent the inherent structure of document clusters by non-negative matrix factorization (NMF) based Hadoop. The proposed method can improve the quality of document clustering which uses the class label terms and the term weights based on term mutual information (TMI) with WordNet at a little cost. It also can cluster the big data size of document using the distributed parallel processing based on Hadoop. The experimental results demonstrate that the proposed method achieves better performance than other document clustering methods.
Top-k Supervise Feature Selection via ADMM for Integer Programming

Recently, structured sparsity-inducing based feature selection has become a hot topic in machine learning and pattern recognition. Most of the sparsity-inducing feature selection methods are designed to rank all features by certain criterion and then select the k top-ranked features, where k is an integer. However, the k top features are usually not the top k features and therefore maybe a suboptimal result. In this paper, we propose a novel supervised feature selection method to directly identify the top k features. The new method is formulated as a classic regularized least squares regression model with two groups of variables. The problem with respect to one group of the variables turn out to be a 0-1 integer programming, which had been considered very hard to solve. To address this, we utilize an efficient optimization method to solve the integer programming, which first replaces the discrete 0-1 constraints with two continuous constraints and then utilizes the alternating direction method of multipliers to optimize the equivalent problem. The obtained result is the top subset with k features under the proposed criterion rather than the subset of k top features. Experiments have been conducted on benchmark data sets to show the effectiveness of proposed method.
A National Study of the Impact of Rapid Influenza Testing on Clinical Care in the Emergency Department.

BACKGROUND Rapid influenza diagnostic tests (RIDT) may influence physician decision-making. Single-center studies suggest that influenza diagnosed in association with RIDT reduces ancillary testing and antibiotic prescribing. The extent of RIDT use in US emergency departments (EDs) and their impact on patient management are unknown. We examined the use of RIDT and its effect on influenza management, using a national sample of ED visits. METHODS We performed a retrospective study using data from the National Hospital Ambulatory Medical Care Survey, an annually administered survey capturing a nationally representative sample of visits to US EDs. We identified patient visits in which RIDT was performed and/or influenza was diagnosed across 3 influenza seasons (2007-2009). Ancillary testing and antibiotic and antiviral prescribing were evaluated for 2 groups of patients in whom RIDT was performed (those given or not given a diagnosis of influenza) and a third group in whom influenza was diagnosed but RIDT was not performed. RESULTS Rapid influenza diagnostic tests were performed during 4.2 million visits. Forty-two percent of influenza diagnoses were made in association with RIDT. For patients diagnosed with influenza, ancillary test ordering was lower (45% vs 53% of visits) and there were fewer antibiotic prescriptions (11% vs 23%), and antiviral use was higher (56% vs 19%) when the diagnosis was made in association with RIDT. CONCLUSIONS Influenza diagnoses made in association with RIDT resulted in fewer tests and antibiotic prescriptions and more frequent use of antivirals. This finding suggests that test results influence physician behavior.
The application of fuzzy parameters self-tuning PID controller in MPPT of photovoltaic power system

Because of the uncertainty of changes in light intensity, photovoltaic (PV) array temperature, Load changes and Strongly nonlinear of PV cells, the maximum power point of the PV array always changes as the environment and load change. The fuzzy control can respond quickly to changes in the external environment, to make sure the PV system is always working at the maximum power point. But, because of the feature of fuzzy Control and self-optimize, the system has more serious oscillation near the maximum power point. Proportional-Integral-Derivative (PID) control can eliminate the oscillation effectively and easily. Therefore, a method based on fuzzy parameters selftuning PID controller has been proposed to achieve the PV system control of MPPT (Maximum Power Point Tracking).
Full-diversity quasi-orthogonal space-time block codes for M-PSK modulations

It has been shown that the quasi-orthogonal space-time block codes (QOSTBCs) can achieve full diversity by rotating the constellations of half the transmitted symbols. Although the rotation angle has been analytically derived for QAM constellations, for arbitrary M-PSK, the coding gain maximizing rotation angle can be found only by computer search. In this paper, a set of QOSTBCs for four transmit antennas that achieves full diversity for M-PSK modulations is presented. The orthogonal designs for real constellations and several QOSTBCs are also included in our formulation. With the same maximum-likelihood decoding complexity, the new codes have BER performance identical to the QOSTBC with constellation rotations. Without any constellation expansion, our scheme is superior to the QOSTBC with constellation rotations in implementations
Syntactic Processing in Professional Interpreters: Understanding Ambiguous Sentences in Reading and Translation

This study evaluates the way in which interpreters activate the source language and the target language (TL) when they perform the interpreting task. We focused on syntactic ambiguities. In sentences like Someone shot the servant of the actress who was on the balcony, two antecedents (‘servant’ and ‘actress’) are potential correct agents of the clause (who was on the balcony). Previous studies showed that Native English speakers interpret the second antecedent as the agent (actress); Spanish speakers prefer the first antecedent (servant), and Spanish–English bilinguals do not show any preference. In the present study, we observed the interpreters’ syntactic processing when they either read the ambiguous sentences in Spanish to repeat them in Spanish or read the sentences in Spanish to translate them into English. The way ambiguous sentences were processed depended on the task: professionals did not show a clear attachment preference when they read and repeated sentences, while they used the strategy preferred in the TL when they performed the interpreting task. Interpreters managed TL syntactic properties in a flexible manner during the comprehension phase of the interpreting task.
Altered Calcium Homeostasis and Mitochondrial Dysfunction in Cortical Synaptic Compartments of Presenilin‐1 Mutant Mice

Abstract : Alzheimer's disease is characterized by amyloid β‐peptide deposition, synapse loss, and neuronal death, which are correlated with cognitive impairments. Mutations in the presenilin‐1 gene on chromosome 14 are causally linked to many cases of early‐onset inherited Alzheimer's disease. We report that synaptosomes prepared from transgenic mice harboring presenilin‐1 mutations exhibit enhanced elevations of cytoplasmic calcium levels following exposure to depolarizing agents, amyloid β‐peptide, and a mitochondrial toxin compared with synaptosomes from nontransgenic mice and mice overexpressing wild‐type presenilin‐1. Mitochondrial dysfunction and caspase activation following exposures to amyloid β‐peptide and metabolic insults were exacerbated in synaptosomes from presenilin‐1 mutant mice. Agents that buffer cytoplasmic calcium or that prevent calcium release from the endoplasmic reticulum protected synaptosomes against the adverse effect of presenilin‐1 mutations on mitochondrial function. Abnormal synaptic calcium homeostasis and mitochondrial dysfunction may contribute to the pathogenic mechanism of presenilin‐1 mutations.
ELECTRON MICROSCOPE OBSERVATIONS ON THE CARBOHYDRATE-RICH CELL COAT PRESENT AT THE SURFACE OF CELLS IN THE RAT

Periodic acid-silver methenamine, a fairly specific technique for glycoprotein detection, was used to stain a variety of rat tissues, in the hope of confirming the existence of a carbohydrate-rich "cell coat" at the surface of mammalian cells. It was found that nearly all cells are coated by a thin layer of stained material. Around fibrocytes and migrating blood cells, the layer is uniform and merges with the ground substance. In the nervous system, cells and processes are surrounded with a layer whose density increases in synaptic clefts. Around epithelial cells, the layer outlines apical microvilli, follows lateral interspaces, and extends between cells and basement membrane. The layer is continuous with the middle plate of desmosomes and can be followed within the wide portion of terminal bars. In contrast, staining usually vanishes when two adjacent plasma membranes fuse to form tight junctions. These findings indicate that the stained layer is a "cell coat" located outside the plasma membrane. Since the cell coat is also stained by colloidal thorium, a technique for detection of acidic carbohydrates, this structure presumably contains not only glycoprotein(s) but also acidic residues. The carbohydrates may play a role in holding cells together and in controlling the interactions between cells and environment.
The practice of reporting transfusion‐related acute lung injury: a national survey among clinical and preclinical disciplines

BACKGROUND: Transfusion‐related acute lung injury (TRALI) is hypothesized to be a “two‐hit” entity, in which an inflammatory condition (e.g., sepsis) predisposes to TRALI. TRALI is a clinical diagnosis. Disciplines involved in managing TRALI may differ in decision‐making on the reporting of TRALI.
Extrapolation-Based References Improve Motion and Eddy-Current Correction of High B-Value DWI Data: Application in Parkinson’s Disease Dementia

Purpose Conventional motion and eddy-current correction, where each diffusion-weighted volume is registered to a non diffusion-weighted reference, suffers from poor accuracy for high b-value data. An alternative approach is to extrapolate reference volumes from low b-value data. We aim to compare the performance of conventional and extrapolation-based correction of diffusional kurtosis imaging (DKI) data, and to demonstrate the impact of the correction approach on group comparison studies. Methods DKI was performed in patients with Parkinson’s disease dementia (PDD), and healthy age-matched controls, using b-values of up to 2750 s/mm2. The accuracy of conventional and extrapolation-based correction methods was investigated. Parameters from DTI and DKI were compared between patients and controls in the cingulum and the anterior thalamic projection tract. Results Conventional correction resulted in systematic registration errors for high b-value data. The extrapolation-based methods did not exhibit such errors, yielding more accurate tractography and up to 50% lower standard deviation in DKI metrics. Statistically significant differences were found between patients and controls when using the extrapolation-based motion correction that were not detected when using the conventional method. Conclusion We recommend that conventional motion and eddy-current correction should be abandoned for high b-value data in favour of more accurate methods using extrapolation-based references.
