Tumor blood flow modifying effect of electrochemotherapy with bleomycin.

BACKGROUND Electrochemotherapy combines administration of the chemotherapeutic drug, followed by application of electric pulses in order to increase drug delivery into the cells. The aim of this study was to determine the tumor blood flow modifying effect of electrochemotherapy with bleomycin and correlate it with its antitumor effectiveness and extent of tumor necrosis. MATERIALS AND METHODS Electrochemotherapy of SA-1 subcutaneous tumors in A/J mice was performed by application of electric pulses to the tumors, following administration of bleomycin, and antitumor effectiveness determined by tumor growth delay and tumor cures as well as extent of tumor necrosis. Tumor blood modifying effect of therapy was evaluated by Patent blue staining technique and 86RbCl extraction technique. RESULTS A good correlation of the two methods evaluating tumor blood flow, Patent blue staining and the established 86RbCl extraction technique was found (r = 0.944). Electrochemotherapy resulted in complete and permanent shut down of tumor blood flow within 12 hours, which lasted for at least 5 days. The results on tumor blood flow reduction correlated well with the good antitumor effectiveness of electrochemotherapy and with the extent of the necrosis in the tumors. CONCLUSIONS The results indicate that Patent blue staining technique is a simple and reliable method for estimation of tumor blood flow and that antitumor effectiveness of electrochemotherapy with bleomycin could be partly attributed to its tumor blood modifying and anti-vascular effect.
Highly parallel SNP genotyping reveals high-resolution landscape of mono-allelic Ube3a expression associated with locus-wide antisense transcription

We investigated the allele- and strand-specific transcriptional landscape of a megabase-wide genomic region of mouse Ube3a (ubiquitin protein ligase E3A) by means of a highly parallel SNP genotyping platform. We have successfully identified maternal-specific expression of Ube3a and its antisense counterpart (Ube3a-ATS) in brain, but not in liver. Because of the use of inter-subspecies hybrid mice, this megabase-wide analysis provided high-resolution picture of the transcriptional patterns of this region. First, we showed that brain-specific maternal expression of Ube3a is restricted to the second half part of the locus, but is absent from the first half part. Balance of allelic expression is altered in the middle of the locus. Second, we showed that expression of the brain-specific Ube3a-ATS appeared to be terminated in the region upstream to the Ube3a transcription start site. The present study highlights the importance of locus-wide competition between sense and antisense transcripts.
Feature extraction for a Slepian-Wolf biometric system using LDPC codes

We present an information-theoretically secure biometric storage system using graph-based error correcting codes in a Slepian-Wolf coding framework. Our architecture is motivated by the noisy nature of personal biometrics and the requirement to provide security without storing the true biometric at the device. The principal difficulty is that real biometric signals, such as fingerprints, do not obey the i.i. d. or ergodic statistics that are required for the underlying typicality properties in the Slepian-Wolf coding framework. To meet this challenge, we propose to transform the biometric data into binary feature vectors that are i.i. d. Bernoulli(0.5), independent across different users, and related within the same user through a BSC-p channel with small p< 0.5. Since this is a standard channel model for LDPC codes, the feature vectors are now suitable for LDPC syndrome coding. The syndromes serve as secure biometrics for access control. Experiments on a fingerprint database demonstrate that the system is information-theoretically secure, and achieves very low false accept rates and low false reject rates.
Transcapillary escape rate of albumin and plasma volume in patients with varying degrees of psoriasis

Plasma albumin, plasma volume and the transcapillary escape rate of albumin (TERalb), i.e. the fraction ofthe intravascular mass of albumin that passes to the extravascular space per unit time, were determined using 125I‐labelled albumin in 26 patients with varying degrees of psoriasis. For the patients as a group the plasma albumin concentration and the TERalb values were not significantly different from the control group. This contrasts with earlier findings in erythrodermic patients. The plasma volume was significantly reduced whether it was expressed in relation to body weight, height or surface area (P<0.001). Thus the intravascular mass of albumin (IVM), determined as the product ofthe plasma volume and the plasma albimiin concentration, was also significantly reduced (P<0.001). We found no correlation between the involved skin area and any ofthe above mentioned parameters.
Prediction of river temperature surges is dependent on precipitation method

Urban river systems are particularly sensitive to precipitation‐driven water temperature surges and fluctuations. These result from rapid heat transfer from low‐specific heat capacity surfaces to precipitation, which can cause thermally polluted surface run‐off to enter urban streams. This can lead to additional ecological stress on these already precarious ecosystems. Although precipitation is a first‐order driver of hydrological response, water temperature studies rarely characterize rain event dynamics and typically rely on single gauge data that yield only partial estimates of catchment precipitation. This paper examines three precipitation measuring methods (a statutory automatic weather station, citizen science gauges, and radar estimates) and investigates relationships between estimated rainfall inputs and subhourly surges and diurnal fluctuations in urban river water temperature. Water temperatures were monitored at 12 sites in summer 2016 in the River Rea, in Birmingham, UK. Generalized additive models were used to model the relationship between subhourly water temperature surges and precipitation intensity and subsequently the relationship between daily precipitation totals and standardized mean water temperature. The different precipitation measurement sources give highly variable precipitation estimates that relate differently to water temperature fluctuations. The radar catchment‐averaged method produced the best model fit (generalized cross‐validation score [GCV] = 0.30) and was the only model to show a significant relationship between water temperature surges and precipitation intensity (P < 0.001, R2 = 0.69). With respect to daily metrics, catchment‐averaged precipitation estimates from citizen science data yielded the best model fit (GCV score = 0.20). All precipitation measurement and calculation methods successfully modelled the relationship between standardized mean water temperature and daily precipitation (P < 0.001). This research highlights the potential for the use of alternative precipitation datasets to enhance understanding of event‐based variability in water quality studies. We conclude by recommending the use of spatially distributed precipitation data operating at high spatial (<1 km2) and temporal (<15 min) resolutions to improve the analysis of event‐based water temperature and water quality studies.
Automated Resistor Classification

In this group thesis, we develop an algorithm that allows the automated classification of resistors using image recognition. The algorithm is implemented in an Android app and therefore usable on every Android smartphone. The problem is split into parts and the result is obtained step by step beginning with the localization of the resistor in the captured image and cropping the image such that only the resistor’s body remains. In the following analysis, the color rings are separated from the background and finally assigned a specific color. In the end, it is possible to determine the resistance of the resistor. Our evaluation of the algorithm shows that the resistor localization works with nearly every image and also under different conditions. The detection of the color rings on the body of the resistor also performs well on most of the images. However, our approach to the color assignment turned out to be unreliable. The task is quite difficult because every camera has different saturation and brightness settings. Also, external conditions like shadows and the background have a significant impact on the colors in an image.
A scheme of feature analysis in SAR imaging based on compressed sensing

A scheme of feature analysis in synthetic aperture radar (SAR) imaging based on compressed sensing (CS) is presented. First, a conventional imaging algorithm, such as range-Doppler algorithm or chirp-scaling algorithm, is used to acquire the complex image of the target scene. Then, a greedy algorithm is applied to this complex image to locate the scattering coefficients of the target, where the research of the peak and the removal of the point spread effect are involved. Third, the point set of each target is determined by a clutter method and the range of the target is further fitted by a geometric shape. They are, finally, used to extract the feature parameter of the target. A series of experimental results using real field data demonstrates the effectiveness of our method.
Ieee Transactions on Visualization and Computer Graphics 1 Style Grammars for Interactive Visualization of Architecture

—Interactive visualization of architecture provides a way to quickly visualize existing or novel buildings and structures. Such applications require both fast rendering and an effortless input regimen for creating and changing architecture using high-level editing operations that automatically fill in the necessary details. Procedural modeling and synthesis is a powerful paradigm that yields high data-amplification and can be coupled with fast rendering techniques to quickly generate plausible details of a scene without much or any user interaction. Previously, forward generating procedural methods have been proposed where a procedure is explicitly created to generate a particular content. In this article, we present our work in inverse procedural modeling of buildings and describe how to use an extracted repertoire of building grammars to facilitate the visualization and quick modification of architectural structures and buildings. We demonstrate an interactive application where the user draws simple building blocks and using our system can automatically complete the building " in the style of " other buildings using view-dependent texture mapping or non-photorealistic rendering techniques. Our system supports an arbitrary number of building grammars created from user subdivided building models and captured photographs. Using only edit, copy and paste metaphors, entire building styles can be altered and transferred from one building to another in a few operations, enhancing the ability to modify an existing architectural structure or to visualize a novel building in the style of others.

Bi-directional Amplification of Throughput in a Wireless Multi-Hop Network

In wireless networks, the shared broadcast medium enables interactions among nodes and thus introduction of novel communication modes. This paper introduces and analyzes relaying techniques that increase the achievable throughput in multi-hop wireless networks by taking advantage of the bi-directional traffic flow. Such a relaying technique is termed relaying with bi-directional amplification of throughput (BAT-relaying). The BAT-relaying is utilizing the concept of anti-packets, defined for bi-directional traffic flows. The relay node combines the packets (anti-packets) that are destined for different nodes and broadcasts the combined packet. The first variant, termed decode-and-forward (DF) BAT-relaying, has been proposed before in the literature. It combines the packets by using the XOR operation, which makes such proposal closely related to the network coding approaches. We proposed another type of BAT-relaying based on amplify-and-forward (AF), which utilizes the inherent packet combining that emerges from simultaneous utilization of a multiple access channel. We analyze the achievable throughput of the DF and AF BAT-relaying, regarding the impact of the traffic asymmetry and the channel errors. The unconventionality of this relaying, in particular AF BAT-relaying, opens many possibilities for further research
Contrasting Root and Photosynthesis Traits in a Large-Acreage Canadian Durum Variety and Its Distant Parent of Algerian Origin for Assembling Drought/Heat Tolerance Attributes

In Canada, the world's top exporter of high-protein durum, varietal development over its nearly six-decade history has been driven by a quest for yield improvement without compromise on grain protein content and other quality aspects. Pelissier, a landrace selection from Algeria that was introduced into North America more than a century ago and the variety Strongfield that was released in 2004 are notable. Pelissier, known to elaborate more roots and considered as drought tolerant, has been cultivated commercially and thus deemed adapted. Strongfield has Pelissier in its pedigree, and it remains a high-acreage variety. Strongfield was found to elaborate only about half of the root biomass of Pelissier at maturity in greenhouse trials under well-watered conditions. Extended drought stress caused a significant reduction in the root biomass of both lines. However, Pelissier under drought maintained at least as much root biomass as that of Strongfield under well-watered conditions. In comparison to Pelissier, it had a superior photosynthesis rate (27.16 μmol CO2 m−2 s−1), capacity for carboxylation (Vcmax: 132.83 μmol CO2 m−2 s−1) and electron transport/ribulose-1,5–bisphosphate (RuBP) regeneration (Jmax: 265.40 μmol CO2 m−2 s−1); the corresponding values for Pelissier were 19.62 μmol CO2 m−2 s−1, 91.87 μmol CO2 m−2 s−1, and 163.83 μmol CO2 m−2 s−1, respectively, under well-watered conditions. Under short-term/mild drought conditions, the carbon assimilation rate remained stable in Pelissier while it declined in Strongfield to the Pelissier level. However, Strongfield succumbed to extended drought sooner than Pelissier. Photosynthesis in Strongfield but not Pelissier was found to be sensitive to high temperature stress. These results provide encouraging prospects for further exploitation of beneficial physiological traits from Pelissier in constructing climate-resilient, agronomically favorable wheat ideotypes.
International Journal of Computer Mathematics

Compressive sensing (CS) has inspired signiﬁcant interests because of its compressive capability and lack of complexity on the sensor side. This paper introduces a novel framework of image fusion based on the CS principle. First, we present a study of three sampling patterns and investigate their performance on CS reconstruction. We then propose a novel image fusion algorithm by using an improved sampling pattern. Finally, the CS-based image fusion approach is applied to various image modalities and evaluated both visually and in terms of fusion quality metrics. The simulations demonstrate that CS-based image fusion has a number of perceived advantages in comparison with image fusion in the multiresolution (MR) domain, providing a truly different and more advanced way for fusing multimodality images.
Impact of venous systemic oxygen persufflation supplemented with nitric oxide gas on cold‐stored, warm ischemia–damaged experimental liver grafts

The increasing shortage of donor organs has led to the increasing use of organs from non–heart‐beating donors. We aimed to assess the impact of venous systemic oxygen persufflation (VSOP) supplemented with nitric oxide (NO) gas during the cold storage (CS) of warm ischemia (WI)–damaged experimental liver grafts. Rat livers (n = 5 per group) were retrieved after 30 minutes of WI induced by cardiac arrest (the WI group) and were thereafter preserved for 24 hours by CS in histidine tryptophan ketoglutarate solution. During CS, gaseous oxygen was insufflated via the caval vein with 40 ppm NO (the VSOP‐NO group) or without NO (the VSOP group). Cold‐stored livers without WI served as controls. Liver viability was assessed after the preservation period by normothermic isolated reperfusion for 45 minutes with oxygenated Krebs‐Henseleit buffer. After 45 minutes of reperfusion, the VSOP‐NO–treated livers showed significantly lower alanine aminotransferase values than the WI‐damaged livers (10.2 ± 0.2 versus 78.2 ± 14.6 IU/L), whereas the control livers showed no differences from the VSOP‐NO–treated livers. The mitochondrial enzyme release was lower in the VSOP‐NO group (4.0 ± 0.7 IU/L) versus the WI group (18.2 ± 4.9 IU/L). An increased portal vein pressure was observed throughout reperfusion (45 minutes) in the WI group (21.7 ± 0.2 mm Hg) versus the VSOP‐NO group (12.2 ± 0.8 mm Hg) and the control group (19.9 ± 0.4 mm Hg). Furthermore, the NO concentration in the perfusate after 5 minutes of reperfusion was highest in the VSOP‐NO group. The release of malondialdehyde into the perfusate was significantly reduced in the VSOP‐NO group (0.9 ± 0.1 nmol/mL) versus the WI group (31.3 ± 5.3 nmol/mL). In conclusion, the resuscitation of livers after 30 minutes of WI to a level comparable to that of nonischemically damaged livers is possible with VSOP supplemented with NO gas. Moreover, the application of VSOP with NO minimizes the extent of injuries caused by oxygen free radicals during preservation. Liver Transpl 18:219–225, 2012. © 2011 AASLD.
Duration of Untreated Psychosis Is Associated with Temporal and Occipitotemporal Gray Matter Volume Decrease in Treatment Naïve Schizophrenia

Background Long duration of untreated psychosis (DUP) is associated with poor treatment outcome. Whether or not DUP is related to brain gray matter volume abnormalities in antipsychotic medication treatment naïve schizophrenia remains unclear at this time. Methods Patients with treatment-naïve schizophrenia and healthy controls went through brain scan using high resolution Magnetic Resonance Imaging. DUP was evaluated using the Nottingham Onset Schedule (NOS), and dichotomized as short DUP (≤ 26 weeks) or long DUP (>26 weeks). Voxel-based methods were used for volumetric measure in the brain. Results Fifty-seven patients (27 short DUP and 30 long DUP) and 30 healthy controls were included in the analysis. There were significant gray matter volumetric differences among the 3 groups in bilateral parahippocampus gyri, right superior temporal gyrus, left fusiform gyrus, left middle temporal gyrus, and right superior frontal gyrus (p's<0.01). Compared with healthy controls, the long DUP group had significantly smaller volume in all these regions (p's <0.05). Compared with the short-DUP group, the long-DUP group had significantly smaller volume in right superior temporal gyrus, left fusiform gyrus, and left middle temporal gyrus (p's<0.01). Conclusion Our findings suggest that DUP is associated with temporal and occipitotemporal gray matter volume decrease in treatment naïve schizophrenia. The brain structural changes in untreated psychosis might contribute to poor treatment response and long-term prognosis in this patient population.
Analysis of Intra-Day Volatility under Economic Crisis Conditions

The purpose of this paper is to examine intra-day volatility of the Athens (GI), Frankfurt (DAX) and New York (DJ) Stock Markets under conditions of economic crisis. After utilizing 5 minutes intervals of the periods September – December of 2008 and 2009, a U-shaped intra-day volatility pattern was observed for DJ and an L-shaped one for DAX and GI. The results indicate a sharp spike in the first 30 minutes and some weaker spikes for the rest of the trading. Moreover, the influence of the New York Stock market to the European markets was dominant. At the same time, GI and DAX exhibited a significantly positive correlation, particularly in last quarter of 2008. Finally, volatility of returns was unusually high in 2008, obviously due to the prevailing global financial crisis.
