Published: November 2016

Ischemic stroke is one of the leading causes of mortality and disability worldwide. Dispite the progress of medical knowledge and technologies, the rate of permanent neurological impairment in patients after stroke remains high and effective strategy of restorative treatment is still at the stage of experimental development. Restoration of nervous system functions after stroke implies the activation of endogenous reparative processes, such as angiogenesis, using sources of regenerative medicine, including cell and tissue transplantation. Development of optimal and safe methods of neurotransplantation for stroke is one of the priorities of experimental research in this field.Purpose: to study the effect of post-stroke angiogenesis, stimulated by transplantation of cell suspension from embryonic nervous tissue (TCS-ENT) and bone marrow (TCS-BM), on restoration of motor functions in rats with experimental stroke.Materials and methods. 160 adult (3-4 months old) outbred albino rats weighing between 280-320 g were divided into groups and subgroups depending on the experimental procedure: with isolated middle cerebral artery occlusion (MCAO), intracerebral allotransplantation of cell suspension from embryonic nervous tissue  (MCAO + TCS-ENT),intracerebral autotransplantation of cell suspension from bone marrow (MCAO + TCS-BM) or phosphate-buffered 0.9 % saline infusion (MCAO + PBS) on the 2nd day after MCAO. MCAO was conducted using the modified method of intraluminal monofilament occlusion with blocking of collaterals. Volume of infarction zone was estimated using TTC staining on 7th and 14th day (n = 5 from each group on each day), number of vessels in periinfarct zone was calculated by immunohistochemical staining for CD34 on 7th, 14th and 28th day (n = 6 from each group on each day) after MCAO. Motor deficit was assessed by ledged tapered beam-walking test on 1st, 3rd, 7th, 14th, 21st and 28th day after MCAO (n = 18 from each group on each day).Results.TCS-BM caused the increase in the number of vessels in the periinfarct zone in dynamics, most prominent on 28th day, and decrease in the volume of infarction zone in comparison with other experimental groups, starting on 7th day after MCAO. TCS-ENT and TCS-BM resulted in regression of motor deficit, starting from 3rd and till 28th day after MCAO. The degree of limb motor asymmetry in rats negatively correlated with the number of vessels in periinfarct zone.Conclusion. Transplantation of cell suspension from embryonic nervous tissue and bone marrow promotes the regression of motor impairments in experimental animals due to angiogenic effect, which is more prominent in case of TCS-BM.

Authors: Svitina H. , Kalmukova O. , Shelest D. , Skachkova O. , Garmanchuk L. , Shablii V.
Published: November 2016

We describe the state of the immune system at the late stage of 1,2-dimethylhydrazine (DMH)-induced colon cancer and after administration of placenta-derived multipotent cells (PDMCs). The spleen and thymus indices did not differ among the groups of intact and DMH-treated rats and were not affected by the administration of placenta-derived multipotent cells following the DMH treatment. Moreover, no difference in spontaneous or stimulated phagocytic activity of peritoneal macrophages was observed between healthy rats or the animals with DMH-induced colon cancer (with or without the administration of PDMCs). However, the proliferation of the T cells in the spleen was lower in rats with colon cancer regardless of the administration of PDMCs. Similarly, no changes were observed in the cell cycle distribution of proliferating spleen cells after stimulation by lipopolysaccharide.Conclusion. Our data demonstrate the absence of the active reaction by peritoneal macrophages and spleen cells to a colon cancer at mid/late stage. Additionally, the administration of PDMCs does not result in a measurable anti-tumor immune response.
Bumbling idiots or evil masterminds? Challenging cold war stereotypes about women, sexuality and state socialism
Authors: Ghodsee Kristen , Lisková Kateřina
Published: November 2016

In academic writing, facts about the past generally require the citation of
relevant sources unless the fact or idea is considered ?common knowledge:?
bits of information or dates upon which there is a wide scholarly consensus.
This brief article reflects on the use of ?common knowledge? claims in
contemporary scholarship about women, families, and sexuality as experienced
during 20th century, East European, state socialist regimes. We focus on
several key stereotypes about the communist state and the situation of women
that are often asserted in the scholarly literature, and argue that many of
these ideas uncannily resemble American anti-communist propaganda. When
contemporary scholars make claims about communist intrusions into the
private sphere to effect social engineering or the inefficacy of state
socialist mass organizations or communist efforts to break up the family or
indoctrinate the young, they often do so without citation to previous
sources or empirical evidence supporting their claims, thereby suggesting
that such claims are ?common knowledge.? We believe that those wishing to
assert such claims should link these assertions to concrete originating
sources, lest it turn out the ?common knowledge? derives, in fact, from
western Cold War rhetoric.
Structural realism - the search for a bearer of reality
Authors: Stojanovic Milutin
Published: November 2016

In the last two decades the old debate concerning reality of science shifted
from questions regarding scientific entities to questions regarding
scientific structures. I will present and assess advantages and drawback of
this new realists? focus on structures, and at the same time analyze the
wider picture of development of the scientific realism. The structural
realism will be tackled in the form encountered in works of John Worrall and
James Ladyman. Special attention will be devoted to the relationship of their
solutions to the argument based on the scientific revolutions - the
pessimistic meta-induction. I will argue that these realist?s strategies are
not sufficiently convincing to steer us to make a leap in ontology and
presume the existence of meta-physical structure (regardless of the question
is it scientifically relevant) - in the first place because neither one of
them manages to satisfactorily identify a structure, however general, which
accumulates in the scientific-theory change.

Authors: Safari Amin , Sheibai Davoud
Published: November 2016

This paper presents an efficient Artificial Bee Colony (ABC) algorithm for
solving large scale economic load dispatch (ELD) problems in power networks.
To realize the ELD, the valve-point loading effect, system load demand, power
losses, ramp rate limits and prohibited operation zones are considered here.
Simulations were performed on four different power systems with 3, 6, 15 and
40 generating units and the results are compared with two forms of power
systems, one power system is with a wind power generator and other power
system is without a wind power generator. The results of this study reveal
that the proposed approach is able to find appreciable ELD solutions than
those of previous algorithms.
Performance analysis of coherent FSO system with SSC receiver
Authors: Petkovic Milica , Djordjevic Goran
Published: November 2016

This paper analyzes the performance of coherent free-space optical (FSO)
system employing the switch-and-stay (SSC) dual diversity receiver. The
intensity fluctuations of the optical signal are modeled by Gamma-Gamma
distribution, being caused by atmospheric turbulence. In addition, pointing
errors are taken into account. Novel analytical expressions for the outage
probability are derived. The general scenario of unbalanced average
signal-to-noise ratios (SNRs) of independent and identically distributed SSC
branches is considered, which is further simplified to the balanced SNR case.
The effects of various system and channel parameters are investigated and
discussed.

Authors: Dominovic-Kovacevic Aleksandra , Racic Dusko , Grgic Sanja , Vukojevic Zoran , Milanovic Sladjan , Ilic Tihomir
Published: November 2016

Background/Aim. Diagnosis of amyotrophic lateral sclerosis (ALS) is based on combination of clinical signs and electrophysiological correlates of pathological process which takes place in general. New electrophysiological criteria Awaji-Shima (AS) additionally qualify the complex fasciculations and neurogenically modified potentials of motor units as signs of active lesions of peripheral motor neuron, contrary to previously valid revised El Escorial criteria (rEE). The objective of this research was to determine the clinical significance and advantages of using the AS criteria in patients with ALS. Methods. Thirty patients (59.2 ? 10.9 years, 57% of them with spinal form of the disease) with clinically suspected ALS were monitored from the time of diagnosis until reaching the category of definitive diagnosis or death. The clinical evaluation and electromyographic (EMG) examinations were carried out at 3-month intervals. Results. By applying the AS criteria, the category of probable or definite diagnosis was achieved in all patients with ALS, except in one (96.6%), as contrary to the rEE (33.3%), after 6 months of the follow-up period. The subclinical affection in more than two body regions has been defined through detection of denervation potentials (80% of the patients by using the AS, or 67% by the rEE criteria). The complex fasciculations were registered particularly often in small muscles of the feet (37? 40%). Conclusion. Application of the AS criteria improve the achievment of category of probable or definite diagnosis of ALS by 2.7 months earlier compared to the rEE. This outcome is particularly affected by a higher frequency of positive EMG findings, when the AS criteria were employed. Early determination of diagnosis provides the better perspective and more frequent participation of the ALS patients in pharmacotherapy studies intended to establish new therapeutic options.

Published: November 2016

Background/Aim. Tuberculosis (TB) is a major cause of mortality and morbidity worldwide, affecting different countries disproportionally. Effective diagnosis and treatment of TB saved an estimated 43 million lives between 2000 and 2014. The aim of our study was to show sociodemographic influences, risk factors for the morbidity and clinical characteristics of tuberculosis among residents of northern Kosovo, Serbia, between two decades at the beginning of the 21st century. Methods. A prospective study was conducted at the Department for Pulmonology of the Clinical-health Centre, Kosovska Mitrovica, included all tuberculosis patients treated during two three-year periods, between 2000?2002 and 2012?2014. In total, 134 patients with tuberculosis were treated, 91 in the first observed period and 43 in the second period. Results. In both observed periods, male patients suffered from tuberculosis more frequently. In the first observed period, younger and middle age (18?49) persons suffered from tuberculosis more frequently (p = 0.014). In relation to the place of residence, in the first reporting period there were more patients from urban areas, while in the second, there were significantly more patients from rural areas (p = 0.008). In the second observed period, TB was significantly more associated with chronic obstructive pulmonary disease (p = 0.001) and comorbidities with TB were significantly more frequent (p = 0.006). During the 2000?2002 period, there were more severe clinical forms, with severe radiological changes, bilateral parenchymal and cavernous forms (p = 0.08). Mild unilateral parenchymal lesions were more common in the last 3 years (p = 0.02). Conclusion. Social determinants, older age and comorbidities are the most important risk factors for the persistent number of patients, and therefore this target group needs attention during active approach in TB screening.

Backgroung/Aim. Since the number of elderly persons is gradually increasing worldwide, there is a need to identify the factors that affect the quality of healthy ageing. On the other hand, depression is the most common psychiatric disorder in the elderly and one of the most serious health problems that modern society is facing. Considering the importance of physical activity for healthy ageing, the question is whether there are differences in quality of life and depression in the elderly in relation to the certain characteristics of physical activities practicing. Methods. Differences in the quality of life and occurrence of depression in elderly were examined in relation to duration of a single training session and frequency of physical activities per week. This non-experimental, descriptive and comparative cross-sectional study involved a total of 188 persons aged 65?84 years, where 90 persons are engaged in a physical activity while 98 persons are not. The Older People?s Quality of Life Questionnaire and the Geriatric Depression Scale were used. Results. Statistically significant difference was found in the following domains of quality of life: health, social relationships and psychological and emotional well-being as well as in the total score of quality of life and in the occurrence of depression. The highest values of quality of life and the lowest level of depression manifestation were observed in the group of persons whose single training session lasted for 60 minutes, and in the group of persons engaged in a physical activity twice a week. Conclusion. The main finding indicates that the differences in the duration of a single training session and the frequency of physical activities per week reflect on the overall quality of life, individual domains of quality of life and the occurrence of depression in the elderly persons.

Published: November 2016

Backgrund/Aim. In recent decades noninvasive methods for the assessment and monitoring of liver fibrosis have been developed and evaluated in numerous chronic liver diseases. The aim of this study was to evaluate the diagnostic accuracy of noninvasive markers for fibrosis assessment transient elastography (TE) and biochemical markers using liver biopsy as reference in patients with primary biliary cirrhosis (PBC). Methods. One hundred and twenty-two patients underwent both liver biopsy and blood tests on the same day and TE in a month following the biopsy and the tests. Liver biopsies were reviewed by a single pathologist using the METAVIR scoring system for assessment of liver fibrosis. Aspartate aminotransferase (AST), platelet ratio index (APRI), Forns scores, AST and alanine transaminase (ALT) ratio and TE were compared with liver fibrosis stage in order to determine the best noninvasive marker of liver fibrosis. Results. There was a statistically significant difference (p < 0.05) for the APRI score, Forns index and TE according to stages of liver fibrosis. TE showed superior diagnostic performance when compared to other surrogate markers of liver fibrosis that were investigated. Optimal cut-off for TE were 4.25 and 5.9 kPa for diagnosing the presence of fibrosis and distinguishing mild/moderate and advanced stages of fibrosis respectively. The areas under the receiver operating characteristic (AUROC) of TE were 0.963 and 0.865, respectively. Conclusion. Based on our investigation the APRI score, Forns index and TE adequately predict fibrosis stage in patients with primary biliary cirrhosis, but the most sensitive and specific parameter appears to be TE. Using noninvasive markers and methods in the evaluation of patients in daily clinical practice may reduce, but not eliminate, the need for invasive diagnostic procedures.

Published: November 2016

Background/Aim. A great number of syndactyly release techniques have been described over last two centuries. The aim of our study is outcome assessment of congenital syndactyly surgery using temporary tissue expansion of the dorsal hand and local flaps, without skin grafts. Methods. This study included children with congenital hand syndactyly treated in period from 2009?2015 by operative technique with temporary tissue expansion of the dorsal hand skin and local flaps, without skin grafting. In all cases surgery was performed under general anesthesia. According to Weber?s descriptive method, the functional outcome at the end of the follow-up period was categorized as good, fair or bad. All patients were evaluated for associated anomalies. Results. A total of 26 children (20 males, 6 females), aged from 6 months to 6 years (average age of 23 months), were operated by previously described technique. There were 20 patients with complete syndactyly and 6 with incomplete, mostly involving the third web. Associated anomalies were diagnosed in 9 patients. The follow-up period ranged from 1 to 5 years with average duration of 2.6 years. The functional results were good in 20 patients, fair in 5 and bad in 1 patient. Conclusion. Surgical procedure with temporary tissue expansion of the dorsal hand skin and local flaps, without skin grafting is effective method of congenital syndactyly treatment in children with good functional and aesthetic results. The advantages of this technique are the reduction of surgery duration and avoiding certain complications, such as web hair growth, hyperpigmentation and hypertrophic scars.

Authors: Ivanov Dejan , Zivojinov Mirjana , Ranisavljevic Milan
Published: November 2016

Introduction. Epithelioid sarcoma is a slow-growing malignant soft tissue tumor and occurs approximately in 1% of all soft tissue malignant tumors. This case report describes epithelioid sarcoma in femoral nerve and as we know it is the first described case of epithelioid sarcoma at this anatomical localisation. Case report. A 44-years-old female patient presented with strong pain in her left leg. On magnetic resonance imaging (MRI), tumor was presented as a node 8 cm in the diameter at left femoral nerve between ileopsoas and iliacus muscle, without infiltration of muscle fascia and tendons. Four enlarged lymph nodes described in left iliac fosa, were suspected on secondary tumor deposits. We preformed radical surgical excision of the tumor and femoral nerve transection with local lymp hnode disection. Histopathological analysis revealed epithelioid sarcoma, and tumor stained highly positive for anti-pan cytokeratin antibody (AE1/AE3), vimentin, cancer antigen 125 (CA125), anticytokeratin antibody (MNF116), hematopoietic progenitor cell antigen (CD34) and epithelial membrane antigen (EMA) markers. After the operation patient recived radiotherapy without chemotherapy. Six months postoperatively, there was no evidence of local relapses or distant metastases. Conclusion. Initial wide surgical resection and adjuvant radiotherapy is beneficial in treatment of epitheloid sarcoma.

Authors: Cupurdija Vojislav , Cekerevac Ivan , Petrovic Marina , Kostic Gordana , Susa Romana , Lazic Zorica
Published: November 2016

Introduction. Montelukast is a selective leukotriene receptor antagonist. One of side effects of this drug class is the Churg-Strauss syndrome (CSS). There is still no reliable evidence whether the expression of this syndrome could be masked by high doses of corticosteroids and become expressed by termination of corticosteroid use, or whether it could be a consequence of leukotriene receptor antagonists use. Case report. Female patient, aged 49 years, was hospitalized with symptoms of fever, dyspnea, cough and increased sputum production with occasional hemoptysis. She was treated for asthma during the previous year. Leukocyte differential formula registered 44% of eosinophils. IgE value was extremely elevated, with value measured to 580 kU/L and eosinophile cation protein value was 15.1 ?g/L. Computed tomography of the chest described changes in the form of ground glass located in all lobes of the right lung and in the upper lobe of the left lung. Computed tomography of paranasal sinuses described changes that could resemble to polyposis, chronic sinusitis, and possible granulomatosis. Mononeuritis of peroneal nerve of the right leg was proven by electromyographic examination. Bone marrow biopsy indicated hypercellularity with domination of eosinophilic granulocytes (30%). Five out of six criteria were noted in patient?s clinical presentation, after which the diagnosis of CSS was set. The patient began treatment with high doses of corticosteroids while montelukast was discontinued which resulted in disease remission. Conclusion. Although there is no evidence that leukotriene modifiers cause the CSS in all patients with asthma, in case of frequent exacerbations with the appearance of pulmonary infiltrates, eosinophilia and paranasal sinus abnormalities make one think of this form of vasculitis.

Authors: Papaioannidou Paraskevi , Kasviki Paschalina
Published: November 2016

Background/Aim. Under the current financial crisis in Greece, an effort has been made by the Greek health authorities to encourage generic prescribing, in order to lower medicinal cost. The purpose of this work was to study antipsychotics use, and to calculate utilization of generics in antipsychotics sales in a sample from the medicines market of Thessaloniki, the second largest city in Greece. Methods. A sample of antipsychotics registered sales was collected using the new Electronic Health Records that have been applied in pharmacies during the last years in Greece. The sample corresponded to a small amount of sales from the market of Thessaloniki during the period July 2014?June 2015, including only community and no hospital sales. All brand names (prototype and generics) of antipsychotics and their relative ratios in the sales were estimated, and the percentage of generics in the sale of each medicine was calculated. The amount of medicines was estimated in Defined Daily Doses (DDDs) of the reference/prototype drug and its generics. Results. Olanzapine, quetiapine, haloperidol and risperidone sales corresponded to 77% of total antipsychotics sales with percentages of sales 25%, 19%, 19% and 14% respectively. The percentage of sales of other antipsychotics was 7% for amisulpride, 6% for aripiprazole, 4% for ziprasidone and 3% for clozapine. Generic use corresponded to 41% of total sales of antipsychotic drugs (10.884 DDDs out of 26.433 DDDs). Concerning second generation antipsychotics, generic use was high for amisulpride, olanzapine, risperidone and quetiapine. Conclusion. In the study sample, second generation antipsychotics corresponded to 78% of sales in the community of Thessaloniki. Haloperidol utilization was also notable. Considering Greek practices, the percentage of generics in antipsychotics sales was very high even for some of the newest antipsychotics.
Synthesis and Surface/Interfacial Properties of Novel Dialkyl Disulfonate Gemini Surfactants Derived from 1,3,5-triazine
Authors: Niu Ruixia , Wang Chao , Song Hua , Wang Jingling , Wang Daqiang , Ren Weidong
Published: November 2016

A series of novel dialkyl disulfonate Gemini surfactants (Cn-GSBS, n = 8, 12, 14, 16, n is the carbon number of the hydrophobic chain) was synthesized from cyanuric chloride, aliphatic amine, ethylenediamine, N,N'-dimethyl-1,3-propyldiamine and sodium 2-chloroethanesulfonate. The chemical structures of the prepared compounds were confirmed by FT-IR and 1H NMR. The critical micelle concentrations (CMC) in aqueous solutions at 25°C were determined by surface tension method. The CMC value decreased with increasing length of the carbon chain. The CMC reached a minimum as low as 5 × 10−5 mol · L−1 for C16-GSBS. The interfacial tensions (IFT) between Daqing crude oil and Cn-GSBS surfactant solutions were also measured. The effects of the concentration of Na2CO3, the concentration and carbon chain length of Cn-GSBS on the IFT of crude oil-water were investigated in detail. The results show that, for the aqueous surfactant system containing the weak base Na2CO3, oil-water interfacial tension can be reduced to 10−2 mN m−1 orders of magnitude. The results also indicate that with the increase of surfactant concentration and the chain length, the oil-water interfacial tension decreased markedly, which indicates that Cn-GSBS surfactants have a good interface activity. These surfactants are good candidates for weak base-surfactant-polymer EOR process.

Published: November 2016

In biodegradable polymer world nanobiocomposites represent a new group of materials filled with inert nanoparticles that shows very interesting properties and the biodegradability of the matrix. In this work we have studied the effect of the polarity of the organomodified montmorillonite and of the elongational flow on the morphology and the rheological and mechanical properties of a new nanobiocomposite with a matrix of biodegradable PLA based blend. The elastic modulus enhances in presence of the nanofiller and this increase is larger and larger with the increment of the orientation. The tensile strength does not show any significant change at the same level of orientation. Moreover, a brittle-to-ductile transition is observed in the anisotropic sample and this effect is again more evident for the nanocomposite. The raise of the interlayer distance is higher for the more polar montmorillonite, even if the two nanocomposites show about the same final interlayer distance and morphology. Some exfoliation is also observed as a result of the application of the elongational flow.

Authors: Corcione C. Esposito , Acocella M. R. , Giuri A. , Maffezzoli A.
Published: November 2016

Graphene stacks/epoxy nanocomposites were produced and characterized in order to analyse the effect of different graphene precursors on cure reaction of a model epoxy matrix. A kinetic analysis of the cure mechanism of the epoxy resin associated to the catalytical activity of the graphite based fillers was performed by isothermal DSC measurements. The DSC results showed that the addition of all graphite based fillers greatly increased the enthalpy of epoxy reaction and the reaction rate, confirming the presence of a catalytic activity of graphitic layers on the crosslinking reaction between the epoxy resin components (epoxide oligomer and di-amine). A kinetic modelling analysis, arising from an autocatalyzed reaction mechanism, was finally applied to isothermal DSC data, in order to predict the cure mechanism of the epoxy resin in presence of the graphite based nanofiller.

Multiple nerve and tendon transfers: a new strategy for restoring hand function in a patient with C7–T1 brachial plexus avulsions
Authors: Xu Bin , Dong Zhen , Zhang Cheng-Gang , Gu Yu-Dong
Published: November 2016

C7–T1 brachial plexus palsies result in a loss of finger motion and hand function. The authors have observed that finger flexion motion can be recovered after a brachialis motor branch transfer. However, finger flexion strength after this procedure merely corresponds to Medical Research Council Grades M2–M3, lowering the grip strength and practical value of the reconstructed hand. Therefore, they used 2 donor nerves and accomplished double nerve transfers for stronger finger flexion. In a patient with a C7–T1 brachial plexus injury, they transferred the pronator teres branch to the anterior interosseous nerve and the brachialis motor branch to the flexor digitorum superficialis branch for reinnervation of full finger flexors. Additionally, the supinator motor branch was transferred for finger extension, and the brachioradialis muscle was used for thumb opposition recovery. Through this new strategy, the patient could successfully accomplish grasping and pinching motions. Moreover, compared with previous cases, the patient in the present case achieved stronger finger flexion and grip strength, suggesting practical improvements to the reconstructed hand.
Chronic electrocorticography for sensing movement intention and closed-loop deep brain stimulation with wearable sensors in an essential tremor patient

Published: November 2016

Deep brain stimulation (DBS) has become a widespread and valuable treatment for patients with movement disorders such as essential tremor (ET). However, current DBS treatment constantly delivers stimulation in an open loop, which can be inefficient. Closing the loop with sensors to provide feedback may increase power efficiency and reduce side effects for patients. New implantable neuromodulation platforms, such as the Medtronic Activa PC+S DBS system, offer important data sources by providing chronic neural sensing capabilities and a means of investigating dynamic stimulation based on symptom measurements. The authors implanted in a single patient with ET an Activa PC+S system, a cortical strip of electrodes on the hand sensorimotor cortex, and therapeutic electrodes in the ventral intermediate nucleus of the thalamus. In this paper they describe the effectiveness of the platform when sensing cortical movement intentions while the patient actually performed and imagined performing movements. Additionally, they demonstrate dynamic closed-loop DBS based on several wearable sensor measurements of tremor intensity.
Efficacy Analysis of Ratios from Pairwise Comparisons
Authors: Wedley William C. , Choo Eng U. , Wijnmalen Diederik J. D.
Published: November 2016

The true pairwise comparison matrix is simulated and used as a benchmark for evaluating different priority vectors derived from a decision maker’s pairwise comparison matrix. The accuracy of the decision maker’s comparisons are progressively improved until they emulate the true values. Using four different distance measures to evaluate five different methods of deriving priorities, the geometric mean, normalized column mean, and right eigenvector techniques are more accurate. All methods exhibit rare reversals in accuracy as the comparison values approach the true values.

Authors: Peng Xindong , Yuan Huiyong
Published: November 2016

In this paper, some new inequalities of Pythagorean fuzzy weighted averaging (PFWA) operator are explored. Later, we develop some Pythagorean fuzzy point operators and introduce generalized Pythagorean fuzzy weighed averaging (GPFWA) operator. Moreover, combining the Pythagorean fuzzy point operators with GPFWA operator, we present some generalized Pythagorean fuzzy point weighted averaging (GPFPWA) operators, which can adjust the degree of the aggregated arguments with some parameters. Based on GPFPWA operators and normal distribution, an approach to multiple attribute decision making (MADM) problem with completely unknown weight information is proposed under Pythagorean fuzzy environment. Finally, an illustrative example is given to show the feasibility and superiority of the developed method.

Published: November 2016

Reliability Hosoya-Wiener polynomial for edge weighted graphs is defined, that can be used as a measure of reliability of a communication network. Each edge is assigned two weights, reliability and communication delay. Some basic properties are given and a recursive formula for the reliability Hosoya-Wiener polynomial of a rooted tree is proved that yields a linear time algorithm on weighted trees. On general graphs, the reliability Hosoya-Wiener polynomial can be computed in O( n3) time.

Published: November 2016

Background: Cell therapy is a promising approach for Parkinson’s disease (PD). Others and we have previously shown that transplantation of ventral mesencephalic fetal cells into substantia nigra (SN) in an animal model of PD enables anatomical and functional repair of the degenerated pathway. However, the molecular basis of this repair is still largely unknown.

Objective: In this work, we studied the expression of several axon guidance molecules that may be implicated in the repair of the degenerated nigrostriatal pathway.

Methods: The expression of axon guidance molecules was analyzed using qRT-PCR on five specific regions surrounding the nigrostriatal pathway (ventral mesencephalon (VM), thalamus (Thal), medial forebrain bundle (MFB), nucleus accumbens (NAcc) and caudate putamen (CPu)), one and seven days after lesion and transplantation.

Results: We showed that mRNA expression of specific axon guidance molecules and their receptors is modified in structures surrounding the nigrostriatal pathway, suggesting their involvement in the axon guidance of grafted neurons. Moreover, we highlight a possible new role for semaphorin 7A in this repair.

Conclusion: Overall, our data provide a reliable basis to understand how axons of grafted neurons are able to navigate towards their targets and interact with the molecular environment in the adult brain. This should help to improve the efficiency of cell replacement approaches in PD.

Effective intercalation of zein into Na-montmorillonite: role of the protein components and use of the developed biointerfaces
Authors: Alcântara Ana C S , Darder Margarita , Aranda Pilar , Ruiz-Hitzky Eduardo
Published: November 2016

Biohybrid materials based on the intercalation of zein, the major storage protein in corn, into sodium-exchanged montmorillonite were prepared following two synthesis strategies. The first one made use of zein dissolved in 80% (v/v) ethanol/water solution, the usual solvent for this protein, while the second method is new and uses a sequential process that implies the previous separation of zein components in absolute ethanol. This treatment of zein with ethanol renders a soluble yellow phase and an agglomerate of insoluble components, which are able to intercalate the layered silicate when an aqueous dispersion of montmorillonite is added to the ethanol medium containing both phases. The diverse steps in this second route were investigated individually in order to understand the underlying mechanism that drives to the intercalation of this complex hydrophobic biomacromolecule into the hydrophilic interlayer space of sodium-exchanged montmorillonite. In addition to physicochemical characterization of the resulting materials, these biohybrid interfaces were also evaluated as biofillers in the preparation of diverse ecofriendly nanocomposites.
MODELING THE SOLAR WIND AT THE ULYSSES, VOYAGER, AND NEW HORIZONS SPACECRAFT

Published: November 2016

The outer heliosphere is a dynamic region shaped largely by the interaction between the solar wind and the interstellar medium. While interplanetary magnetic field and plasma observations by the Voyager spacecraft have significantly improved our understanding of this vast region, modeling the outer heliosphere still remains a challenge. We simulate the three-dimensional, time-dependent solar wind flow from 1 to 80 astronomical units (au), where the solar wind is assumed to be supersonic, using a two-fluid model in which protons and interstellar neutral hydrogen atoms are treated as separate fluids. We use 1 day averages of the solar wind parameters from the OMNI data set as inner boundary conditions to reproduce time-dependent effects in a simplified manner which involves interpolation in both space and time. Our model generally agrees with Ulysses data in the inner heliosphere and Voyager data in the outer heliosphere. Ultimately, we present the model solar wind parameters extracted along the trajectory of the New Horizons spacecraft. We compare our results with in situ plasma data taken between 11 and 33 au and at the closest approach to Pluto on 2015 July 14.
THE ELECTRON DENSITY IN EXPLOSIVE TRANSITION REGION EVENTS OBSERVED BY IRIS
Authors: Doschek G. A. , Warren H. P. , Young P. R.
Published: November 2016

We discuss the intensity ratio of the O iv line at 1401.16 Å to the Si iv line at 1402.77 Å in Interface Region Imaging Spectrograph (IRIS) spectra. This intensity ratio is important if it can be used to measure high electron densities that cannot be measured using line intensity ratios of two different O iv lines from the multiplet within the IRIS wavelength range. Our discussion is in terms of considerably earlier observations made from the Skylab manned space station and other spectrometers on orbiting spacecraft. The earlier data on the O iv and Si iv ratio and other intersystem line ratios not available to IRIS are complementary to IRIS data. In this paper, we adopt a simple interpretation based on electron density. We adopt a set of assumptions and calculate the electron density as a function of velocity in the Si iv line profiles of two explosive events. At zero velocity the densities are about 2–3 × 1011 cm−3, and near 200 km s−1 outflow speed the densities are about 1012 cm−3. The densities increase with outflow speed up to about 150 km s−1 after which they level off. Because of the difference in the temperature of formation of the two lines and other possible effects such as non-ionization equilibrium, these density measurements do not have the precision that would be available if there were some additional lines near the formation temperature of O iv.

Until recently, only a handful of dusty, star-forming galaxies (DSFGs) were known at z > 4, most of them significantly amplified by gravitational lensing. Here, we have increased the number of such DSFGs substantially, selecting galaxies from the uniquely wide 250, 350, and 500 μm Herschel-ATLAS imaging survey on the basis of their extremely red far-infrared colors and faint 350 and 500 μm flux densities, based on which, they are expected to be largely unlensed, luminous, rare, and very distant. The addition of ground-based continuum photometry at longer wavelengths from the James Clerk Maxwell Telescope and the Atacama Pathfinder Experiment allows us to identify the dust peak in their spectral energy distributions (SEDs), with which we can better constrain their redshifts. We select the SED templates that are best able to determine photometric redshifts using a sample of 69 high-redshift, lensed DSFGs, then perform checks to assess the impact of the CMB on our technique, and to quantify the systematic uncertainty associated with our photometric redshifts, σ = 0.14 (1 + z), using a sample of 25 galaxies with spectroscopic redshifts, each consistent with our color selection.

ON THE WHITE DWARF MASS PROBLEM OF CATACLYSMIC VARIABLES
Authors: Liu Wei-Min , Li Xiang-Dong
Published: November 2016

Recent observations show that white dwarfs (WDs) in cataclysmic variables (CVs) have an average mass significantly higher than isolated WDs and WDs in post-common envelope binaries (PCEBs), which are thought to be the progenitors of CVs. This suggests that either the WDs have grown in mass during the PCEB/CV evolution or the binaries with low-mass WDs are unable to evolve to be CVs. In this paper, we calculate the evolution of accreting WD binaries with updated hydrogen accumulation efficiency and angular momentum loss (AML) prescriptions. We show that thermal-timescale mass transfer is not effective in changing the average WD mass distribution. The WD mass discrepancy is most likely related to unstable mass transfer in WD binaries, in which an efficient mechanism of AML is required.
