Topical haemoglobin spray for diabetic foot ulceration
Authors: Bateman Sharon Dawn 
Published: June 2015

The development and subsequent deterioration of diabetic foot ulceration (DFU) is a common occurrence across all healthcare divides, concerning all patient groups, age, gender and social environments. It increases demand on clinical resources and creates unnecessary hardship for patients. Chronic DFU is challenging to prevent and notoriously difficult to manage owing to the complex nature of the patient and the disease itself. The improvement of oxygenation to many chronic wound groups is gaining momentum across wound care; particularly in those wounds such as DFU that present with circulatory, oxygen-deficient scenarios. Method: A descriptive evaluation was undertaken in an acute clinical setting where a spray solution containing purified haemoglobin was used in a cohort of 20 patients who presented with chronic (>12 weeks) DFU. Standard wound care was undertaken by 18 health professionals with no changes to products, devices or practice before evaluation. All wounds received the addition of the product on eight set occasions over a 4-week period and the resulting data correlated in regards to the set outcomes of wound surface area reduction, ease of use, adverse events and patient acceptability. Results: At 4 weeks all wounds had demonstrated positive wound reduction, there were no adverse events, all patients and clinicians found the product acceptable and easy to use. Interestingly, although not a set outcome, all wounds commenced the evaluation with wound-bed slough present and at 4 weeks 100% were deemed slough free. At a further 4-week review no patients wounds had regressed. Conclusion: The incorporation of a haemoglobin spray solution within this cohort of DFU resulted in a positive improvement in wound healing and slough elimination. Further work in this area is recommended to increase the evidence.
Genotoxic effects of diazinon on human peripheral blood lymphocytes / Genotoksično djelovanje diazinona na limfocite ljudske periferne krvi

Published: June 2015

Abstract
The aim of this study was to evaluate the genetic damage in human peripheral blood lymphocytes following 24 and 48- hour exposure to a commercial diazinon formulation Basudin 60EM® at concentrations between 0.01 and 40 μg mL-1. For this purpose we used the micronucleus (MN), fluorescence in situ hybridization (FISH), and alkaline single cell gel electrophoresis (comet) assay. Diazinon significantly increased the frequency of micronucleated cells compared to control. Forty-eight-hour exposure increased this frequency even at lower concentrations (0.01-10 μg mL-1). The FISH results revealed aneugenic effects at 10 μg mL-1. The comet assay also confirmed DNA damage at concentrations between 10 and 40 μg mL-1. Our findings have confirmed the genotoxic potential of diazinon and its cytotoxic effect on human lymphocytes. The increased DNA damage in our study raises concern about the current assessment of the health risk posed by this pesticide and calls for a high level of caution in agricultural and household use.
ADHD-like behaviour in the offspring of female rats exposed to low chlorpyrifos doses before pregnancy / Ponašanje nalik ADHD-u u potomaka ženki štakora izloženih niskim dozama klorpirifosa prije trudnoće
Authors: Grabovska Sofia , Salyha Yuriу 
Published: June 2015

Abstract
The aim of this study was to investigate how chronic low-dose chlorpyrifos exposure of female Wistar rats before and during pregnancy affects behavioural parameters in their offspring. Four months before pregnancy, we exposed three groups of rats to chlorpyrifos doses of 5, 10, and 15 mg kg-1 body weight every day for 30 days, whereas one group received a single 30 mg kg-1 dose on gestational day 6. When the offspring of the exposed rats grew up, we studied their anxiety rate, motor activity, and cognitive abilities using the respective behavioural tests: open field test, dark/light box, and the extrapolation escape test. The offspring of rats exposed before pregnancy had significantly higher activity rate than controls, and even showed motor agitation and hyperactivity signs. The offspring of rats exposed to the single dose had difficulties solving the extrapolation escape test and showed poorer short- and long-term memory performance. This confirmed that even pre-pregnancy chlorpyrifos exposure can cause neurobehavioral consequences in offspring. Even though the mechanisms of the observed changes remain unclear and need further investigation, these data seem alarming and may serve as an important argument for revising the terms of safe pesticide use
Modelling of copper(II) binding to pentapeptides related to atrial natriuretic factor using the 3χv connectivity index / Modeliranje vezivanja bakra(II) za pentapeptide povezane s atrijalnim natriuretičkim faktorom pomoću indeksa povezanosti 3χv
Authors: Miličević Ante , Raos Nenad 
Published: June 2015

Abstract
Using molecular graph theory we studied the binding of NSFRY-NH2 and 12 related pentapeptide amides to Cu(II) as a model system for atrial natriuretic factor (ANF) peptide interactions with copper. Linear regression models based on the valence connectivity index of the 3rd order (3χv) reproduced experimental stability constants (log β) for 1N, 2N, 3N, and 4N coordinated complexes with the standard error of 0.30-0.39 log β units. We developed separate models for seven tyrosinic (N=28) and five non-tyrosinic peptides (N=20), and a common model for both kinds of peptides (N=48) with an indicator (dummy) variable. The results indicate additional aromatic stabilisation in 4N complexes due to metal cation-π interactions with tyrosine but not with the phenylalanine residue. We have also amended the log K and log K* values to correct miscalculations published by Janicka-Klos et al. in 2013
On-line parameter and delay estimation of continuous-time dynamic systems
Authors: Kozłowski Janusz , Kowalczuk Zdzisław 
Published: June 2015

Abstract
The problem of on-line identification of non-stationary delay systems is considered. The dynamics of supervised industrial processes are usually modeled by ordinary differential equations. Discrete-time mechanizations of continuous-time process models are implemented with the use of dedicated finite-horizon integrating filters. Least-squares and instrumental variable procedures mechanized in recursive forms are applied for simultaneous identification of input delay and spectral parameters of the system models. The performance of the proposed estimation algorithms is verified in an illustrative numerical simulation study.
Using symbolic computation in the characterization of frictional instabilities involving orthotropic materials
Authors: Agwa Mohamed A. , Pinto Da Costa António 
Published: June 2015

Abstract
The present work addresses the problem of determining under what conditions the impending slip state or the steady sliding of a linear elastic orthotropic layer or half space with respect to a rigid flat obstacle is dynamically unstable. In other words, we search the conditions for the occurrence of smooth exponentially growing dynamic solutions with perturbed initial conditions arbitrarily close to the steady sliding state, taking the system away from the equilibrium state or the steady sliding state. Previously authors have shown that a linear elastic isotropic half space compressed against and sliding with respect to a rigid flat surface may get unstable by flutter when the coefficient of friction μ and Poisson’s ratio ν are sufficiently large. In the isotropic case they have been able to derive closed form analytic expressions for the exponentially growing unstable solutions as well as for the borders of the stability regions in the space of parameters, because in the isotropic case there are only two dimensionless parameters (μ and ν). Already for the simplest version of orthotropy (an orthotropic transversally isotropic material) there are seven governing parameters (μ, five independent material constants and the orientation of the principal directions of orthotropy) and the expressions become very lengthy and literally impossible to manipulate manually. The orthotropic case addressed here is impossible to solve with simple closed form expressions, and therefore the use of computer algebra software is required, the main commands being indicated in the text.
Local dependency in networks

Published: June 2015

Abstract
Many real world data and processes have a network structure and can usefully be represented as graphs. Network analysis focuses on the relations among the nodes exploring the properties of each network. We introduce a method for measuring the strength of the relationship between two nodes of a network and for their ranking. This method is applicable to all kinds of networks, including directed and weighted networks. The approach extracts dependency relations among the network’s nodes from the structure in local surroundings of individual nodes. For the tasks we deal with in this article, the key technical parameter is locality. Since only the surroundings of the examined nodes are used in computations, there is no need to analyze the entire network. This allows the application of our approach in the area of large-scale networks. We present several experiments using small networks as well as large-scale artificial and real world networks. The results of the experiments show high effectiveness due to the locality of our approach and also high quality node ranking comparable to PageRank.
Can interestingness measures be usefully visualized?
Authors: Susmaga Robert , Szczęch Izabela 
Published: June 2015

Abstract
The paper presents visualization techniques for interestingness measures. The process of measure visualization provides useful insights into different domain areas of the visualized measures and thus effectively assists their comprehension and selection for different knowledge discovery tasks. Assuming a common domain form of the visualized measures, a set of contingency tables, which consists of all possible tables having the same total number of observations, is constructed. These originally four-dimensional data may be effectively represented in three dimensions using a tetrahedron-based barycentric coordinate system. At the same time, an additional, scalar function of the data (referred to as the operational function, e.g., any interestingness measure) may be rendered using colour. Throughout the paper a particular group of interestingness measures, known as confirmation measures, is used to demonstrate the capabilities of the visualization techniques. They cover a wide spectrum of possibilities, ranging from the determination of specific values (extremes, zeros, etc.) of a single measure, to the localization of pre-defined regions of interest, e.g., such domain areas for which two or more measures do not differ at all or differ the most.
A generalization of the graph Laplacian with application to a distributed consensus algorithm
Authors: Zhai Guisheng 
Published: June 2015

Abstract
In order to describe the interconnection among agents with multi-dimensional states, we generalize the notion of a graph Laplacian by extending the adjacency weights (or weighted interconnection coefficients) from scalars to matrices. More precisely, we use positive definite matrices to denote full multi-dimensional interconnections, while using nonnegative definite matrices to denote partial multi-dimensional interconnections. We prove that the generalized graph Laplacian inherits the spectral properties of the graph Laplacian. As an application, we use the generalized graph Laplacian to establish a distributed consensus algorithm for agents described by multi-dimensional integrators.
An application framework to systematically develop complex learning resources based on collaborative knowledge engineering
Authors: Gañán David , Caballé Santi , Conesa Jordi , Xhafa Fatos 
Published: June 2015

Abstract
This contribution proposes software infrastructure to support new types of learning methodologies and resources based on collaborative knowledge engineering by means of an innovative application framework called the virtualized collaborative sessions framework (VCSF). The VCSF helps meet challenging collaborative knowledge engineering requirements in online learning, such as increasing group members’ learning performance during the on-line collaborative learning process. In turn, systematic application of the VCSF platform enriched with semantic knowledge engineering technologies enables e-learning developers to leverage successful collaborative learning experiences in a software reuse fashion while saving development time and effort. The framework is prototyped and successfully tested in real environments, thus showing the software reuse capability and the collaborative knowledge engineering benefits of the VCSF approach. The research reported in this paper was undertaken within the ALICE project funded through the European 7th Framework Program (FP7).
Sender-equivocable encryption schemes secure against chosen-ciphertext attacks revisited
Authors: Huang Zhengan , Liu Shengli , Qin Baodong , Chen Kefei 
Published: June 2015

Abstract
Fehr et al. (2010) proposed the first sender-equivocable encryption scheme secure against chosen-ciphertext attacks (NCCCA) and proved that NC-CCA security implies security against selective opening chosen-ciphertext attacks (SO-CCA). The NC-CCA security proof of the scheme relies on security against substitution attacks of a new primitive, the “crossauthentication code”. However, the security of the cross-authentication code cannot be guaranteed when all the keys used in the code are exposed. Our key observation is that, in the NC-CCA security game, the randomness used in the generation of the challenge ciphertext is exposed to the adversary. Based on this observation, we provide a security analysis of Fehr et al.’s scheme, showing that its NC-CCA security proof is flawed. We also point out that the scheme of Fehr et al. encrypting a single-bit plaintext can be refined to achieve NC-CCA security, free of the cross-authentication code. Furthermore, we propose the notion of “strong cross-authentication code”, apply it to Fehr et al.’s scheme, and show that the new version of the latter achieves NC-CCA security for multi-bit plaintexts.

Published: June 2015

Abstract
The use of equid milk in human nutrition is a very interesting research topic in relation to the specific characteristics of this drink. Mare’s milk has a composition similar to human milk and is well digested, so it is a perfect alternative to cow’s milk in the feeding of children who are allergic to cow’s milk. Equid milk’s low content of α-lactalbumin and β-lactoglobulin makes it appropriate for such children. Its high concentration of lactose allows for a better growth of intestinal microflora. Mare’s milk is characterised by a high content of lysozyme, lactoferrin and lactadherin and has an inhibiting effect on the development of pathogenic bacteria. Research done so far indicates that it may be helpful in treating atopic dermatitis as well as in improving skin appearance. The high content of vitamin C in mare’s milk influences its antioxidant value. Due to its lower content of fat and cholesterol it can be used to lower cholesterol intake as well as to control cardiovascular diseases. Mare’s milk has been proved to play a role in curing Crohn’s disease, ulcerative colitis, as well as hepatitis and chronic gastric ulcers. The qualities of mare’s milk make it appropriate for use in children’s and elderly people’s nutrition in prophylaxis and as an aid to the process of curing various diseases.
The Middle East Respiratory Syndrome Coronavirus (Mers-CoV) – What is the Risk? A Review of Recent Studies
Authors: Józefiak Agata , Woźniak Mariusz , Jaśkowski Jędrzej M. 
Published: June 2015

Abstract
MERS (Middle East Respiratory Syndrome) is a viral disease of the respiratory system caused by coronaviruses (CoV), which can be contagious to both animals and humans. It was first described in 2012 in Saudi Arabia and very quickly its occurrence was found in European countries. Initially, it was associated with mild changes within the respiratory system, until a new type of virus was isolated in a patient with severe pneumonia and renal failure, who died. The study showed a close relationship between the virus isolated from the patient’s cells with HKU4 and HKU5 coronaviruses, previously isolated from bats. The presence of the same virus was found in a patient from Qatar with a similar clinical image. MERS infections, despite relatively low infectivity, are characterized by high mortality (30%). It is believed that the most likely source of the virus for humans are camels. The objective of this article is to review and discuss data on the risk factors of MERS-CoV zoonotic transmission from animals to humans.

Authors: Kantanista Adam , Król-Zielińska Magdalena , Borowiec Joanna , Glapa Agata , Lisowski Paweł , Bronikowski Michał 
Published: June 2015

Summary
Study aim: the aim of this study was to assess the step counts of children and adolescents with different BMIs and to present the results in relation to the step count recommendation.

Material and methods: the study included data from 175 girls, aged 12–18 (45 participants from primary school, 69 participants from junior high school and 61 participants from high school). Voluntary participants were recruited from public schools in Poland. Step counts were measured using pedometers (Yamax Digi-Walker SW 701) over seven consecutive days.

Results: the recommended level of 12000 steps per day was achieved by only 14.9% of participants. The step counts performed by girls, especially at the primary school age, are currently insufficient. Participants’ achievement of the recommended step count level correlated with a lower BMI.

Conclusions: few female children and adolescents are meeting daily step recommendations, which highlights the importance of school and community-based programmes designed to increase daily activity patterns.

Authors: Iadreev Vladislav , Cherkashin Ilya , Vujkov Sandra , Drid Patrik 
Published: June 2015

Summary
Study aim: the aim of the study was to identify differences between athletically trained and untrained subjects with respect to body composition, motor and cognitive abilities.

Materials and methods: three groups of girls aged 12 to 14 years old participated in the study: young judokas (n = 42), volleyball players (n = 54) and their untrained peers (n = 54). Variables of interest were assessed through eight motor tests, nine anthropometric variables and the RSPM.

Results: this study showed differences in some anthropometric characteristics and almost all motoric abilities between trained girls and untrained girls (p < 0.05), indicating that well-programmed activity can positively influence these characteristics and abilities. In addition, group of volleyball players presented significantly better results in cognitive abilities (p < 0.01), indicating a need for intelligence in complex sports like volleyball.

Conclusions: generally, the trained groups of athletes possessed better coordination and strength than their untrained counterparts.
An in vivo study of the best light emitting diode (LED) systems for cut chrysanthemums
Authors: Hong Yan , Huang He , Dai Silan 
Published: June 2015

Abstract
The cut chrysanthemum (Chrysanthemum
×morifolium Ramat.) is one of the most recognized cut
flowers in the world. Light quality significantly affects the
development and growth of plants. To conduct an in-depth
investigation of the effects of light quality on the growth
and development of cut chrysanthemums, seedlings of
the cut chrysanthemum cultivar ‘Riqietaohong’ were
cultured under four different light emitting diode (LED)
systems: red (R), blue (B), red : blue = 2:1 (RB) and blue
: red = 2:1 (BR). A fluorescent lamp was used for control
group lighting. The Duncan multiple comparisons
analysis showed that the B light promoted stem and leaf
development of seedlings but inhibited photosynthesis.
The R light stimulated their rooting but inhibited the
accumulation of biomass. RB improved transpiration.
Moreover, a comprehensive evaluation system that
combined the analytic hierarchy process (AHP) method
with the technique for order preference by similarity to
an ideal solution (TOPSIS) method indicated that the
photosynthesis index, transpiration index and biomass
index were the most important indicators for the growth
and development of cut chrysanthemums, and RB
was the best LED system for cut chrysanthemums. The
present study provides references for the lower energy
consumption and industrial annual production of cut
chrysanthemums.
Identification and Expression Analysis of
Glutamine Synthetase Genes in Ramie (Boehmeria nivea L. Gaud)
Authors: Zheng Jian-Shu , Yu Chun-Ming , Chen Ping , Wang Yan-Zhou , Liu Tou-Ming , Xiong He-Ping 
Published: June 2015

Abstract
Glutamine synthetase (GS) plays a fundamental
role in nitrogen metabolism in higher plants. Three BnGS
genes have first been isolated: one gene encoding plastid
GS (BnGS2) and two encoding cytosolic GS (BnGS1-1 and
BnGS1-2) in ramie. Based on a sequence analysis and
phylogenetic study, three BnGS sequences were classified
into three distinct sub-families. The phylogenetic analysis
showed that BnGS2 and BnGS1-2 were closely related
to those of legumes, alfalfa (Medicago sativa), soybean
(Glycine max) and bean (Phaseolus vulgaris). The BnGS
gene expression patterns revealed that each gene exhibited
similar organ specificity, but distinct transcript intensity
during different vegetative processes. The relatively
abundant expression of BnGS1-1 and BnGS2 at specific
organs during different vegetative processes indicates that
they have critical roles in nitrogen uptake and assimilation
relating to forage and growth characteristics. The BnGS1-2
mRNA levels were remarkably upregulated in the
phloem, xylem and stems during the fiber development
stage, suggesting a correlation with fiber development.
Therefore, the non-overlapping transcript intensity of
BnGS genes in different tissues regulates ramie growth
and development during different vegetative processes.
Spectropolarimetric analyses of optical single mode SU8 waveguide layers
Authors: Gut K. , Opilski Z. 
Published: June 2015

Abstract
The paper presents the principle of the operation of a spectropolarimetric interferometer. In a planar waveguide orthogonal modes of the TE and TM types can be excited for the entire visible light. During the propagation the difference of the phases between the modes was determined, which is the function of the length of the path of propagation, the difference of the effective refractive index (NTM-NTE) and the wavelength. At the output of this system the spectral distribution of intensity was recorded, the shape of which depends on the value of the refractive index of the cover of the waveguides
