‘Fight Together/Write Together’: Street art as documentation of affect in times of unrest in Athens
Authors: Chiotis Theodoros 
Published: October 2014

Abstract
This visual essay attempts to map how evolving feelings of unrest have been captured in slogans and street art painted on the walls of Athens over the past few years. Slogans and street art demarcate alternative spatialities and alternative subjectivities within the city limits. In effect, slogans and street art function as signs of a community struggling to articulate itself in the face of political stagnation; ontology, politics and art thus become intimately entwined. Street art and graffiti are collective gestures of desire, movement and flux coming from a loosely defined collective of artists and amateurs making use of their artistry to create works which comment, disrupt and create alternative ways of building communities and subjectivities.
A shifting landscape: Contemporary Greek dance and conditions of crisis
Authors: Panagiotara Betina , Tsintziloni Steriani 
Published: October 2014

Abstract
This article introduces a framework for discussing contemporary dance’s potential for critical intervention within the context of the current socio-economic crisis in Europe, focusing on examples from Greece. In particular, it explores how the use of history in recent works proposes new engagements and relationships between past and present, inviting a reconsideration of the past while making possible the envisaging and articulation of emergent narratives, identities and social formations. It also examines the use of collaborative practices for choreographing, which depart from hierarchical dance processes that have been dominant in Greece and thus challenge the prevailing perception of danse d’auteur while exploring different modes of production. The significance of these practices lies in their questioning of previously established modes of working but also in their potential function as models of broader social practices. The works in question are analysed not as artefacts alone but as artistic practices that operate, act and interact within the social, the political and the aesthetic. It is argued that under conditions of socio-political crisis, the established social order is renegotiated and that these works, through the practices with which they engage, are significant in the reconstitution of the social. Thus, they propose a way of reclaiming the social dimension and potential of the arts in a period when their role is disputed.
The militant subject as tragic hero in Dimitris Nollas’s fiction
Authors: Petsa Vasiliki 
Published: October 2014

Abstract
This article focuses on the militant subjects in Dimitris Nollas’s fiction and considers them as tragic heroes that occupy liminal positions. Political violence, as a contested tactical option of militancy, posits pressing dilemmas and generates intricate explorations of morality and agency. After sketching a brief theoretical framework in order to assess recent theories of the tragic, I focus on the novella To Pempto Genos / The Fifth Age (Nollas, 1988) and the novel O Anthropos pou Xehastike / The Man in Limbo (Nollas, 1995) in terms of conflictual memory frames and ethical stances. Although they present similarities on the thematic level, a close reading of the texts elucidates the different approaches taken towards the militant past from the present standpoint and, consequently, the divergent implications for the future.
Lyrical stresses of heavy metal and rap
Authors: Geliebter David , Ziegler Ari J. , Mandery Evan 
Published: October 2014

Abstract
Two hundred and ten college students were played either a rap or heavy metal version of a song and surveyed to determine lyrical recollection and comprehension of the song’s themes. Students who heard the heavy metal version paid less attention to the song’s themes and had worse lyrical recollection. This data strengthens the argument that heavy metal music has a lesser lyrical stress than rap. Consequently, a ‘gangsta’ heavy metal song is less likely to be repeated, taken to heart and acted upon than a gangsta rap song. This finding offers important support for a non-race-based theory explaining the disproportionality between criticism of gangsta heavy metal music and gangsta rap music.
‘Oil complex’ and social responsibility theory of the media: Shaping Nigeria’s environmental discourse with social media
Authors: Uzoechi Nwagbara 
Published: October 2014

Abstract
The aim of this article is to explore how social media can be used to effectively bring behavioural change and rational opinion about ‘oil complex’ in Nigeria’s Niger delta region for a more sustainable future. Second, this article argues that social media can also be used as a medium to shape public opinion, pluralistic views and policy agenda about challenges posed by ‘oil complex’. This process resonates with the social responsibility function of the media. While mainstream or traditional media perceptibly steer clear of reporting issues that highly challenge corporate interests, which have strong links with these media outlets, social media can be a platform for critical and balanced reportage of social and environmental issues for diversity of views to be aired. The media’s role in this sense will help manage problems associated with ‘oil complex’ for a more sustainable future in the region.
Mobile phone users from low socio-economic strata in Asia: The moderating roles of age and gender
Authors: Maity Moutusy 
Published: October 2014

Abstract
This article investigates the continued usage of mobile telecommunication services (voice services and short messaging services (SMS)) among users from low socio-economic groups in Asia, and also examines the moderating effects of demographic variables age and gender on the intention to continue using these services. We investigate the phenomenon of information obtained using voice-based services and non-voice-based services by users from low socio-economic groups. This investigation brings together the Technology Acceptance Model (TAM) framework, and the information search paradigm to suggest a model for continued use of mobile phones. Data collected from individual telecommunication users across five South East Asian countries are analysed through structural equation modelling (SEM) to test the hypotheses. Findings demonstrate that for voice services, perceived ease of use (PEU) significantly affects intention in younger users (and not older users), while usefulness is a stronger predictor of intention for older users. For users of voice services and SMS, PEU significantly affects intention in males only, while subjective norm significantly affects intention only in females. From a public policy perspective, a greater emphasis may be placed on disseminating information about the benefits of mobile telecommunication among potential mobile phone users through groups that influence user behaviour.

Mutations in IL-10R1, IL-10R2, and IL-10 have been identified in infants with severe colitis. The only possible hope for cure in these conditions is a hematopoietic stem cell transplantation (HSCT). We report here on a patient with IL-10R1 deficiency who suffered severe colitis and arthritis. She received a HSCT from a matched unrelated donor and her post-transplant course was uneventful. She has fully engrafted and her immune reconstitution was complete and robust. Although signs of colitis were completely resolved, arthritis was not reversed by HSCT. She continues to have joint swelling in the knees and inflammatory changes in the wrists. In conclusion, HSCT seems to have reversed colitis, but was insufficient to improve arthritis and possibly other autoimmune manifestations. Statement of novelty: This report describes a successful HSCT in severe infantile colitis caused by mutations in IL-10R1. Yet, the arthritis remains active, suggesting that conditions such as severe rheumatic disorders in childhood may not be reversed by replacement of the hematopoietic system.

AbstractDiagnosing patients with signs or symptoms suggestive of cancer is difficult. Serum tumor markers (TM) may be useful, but it is known that a range of pathologies other than cancer can increase their concentrations and so TM data must be interpreted with caution. The aim of this study is to determine the diagnostic accuracy of TMs in patients with signs or symptoms of cancer.We prospectively studied 234 patients seen at rapid diagnostic units who presented signs or symptoms suggestive of cancer. Ninety patients had wasting syndrome, 74 had pulmonary symptoms and 70 other presentations. CYFRA21-1, CEA, CA19-9, total bilirubin and creatinine were determined. The final diagnosis was obtained after 6 months’ follow-up. Patients were classified according to the absence (group A) or presence (group B) of abnormal bilirubin or creatinine.Of the 234 patients studied, 103 (44.0%) had tumors diagnosed. Cut-off points for each TM were calculated for a specificity of 100%. For the total group, the values were CYFRA21-1, 15 μg/L, CEA, 43.8 μg/L and CA19-9, 7428 KU/L, with an overall sensitivity of 46.6%. For group A (n=142), the following cut-off points were established: CYFRA21-1, 7.8 μg/L, CEA, 13.8 μg/L and CA19-9, 101 KU/L, obtaining a sensitivity of 68.6%. For group B (n=92), the values were the same as for the whole group, and a sensitivity of 42.4% was achieved.We conclude that TMs can aid diagnosis in these patients with signs or symptoms suggestive of cancer. Their sensitivity can be improved by using different cut-off points in the presence and absence of renal and hepatic dysfunction.

AbstractThe object of this study was to evaluate biomarkers for diagnosis of sepsis, hematologic parameters, and cytokine profiles for use in the diagnosis and evaluation of severity of sepsis.We enrolled 127 consecutive patients with systemic inflammatory response syndrome (SIRS), 97 of whom were diagnosed with sepsis. The following biomarkers were evaluated: procalcitonin (PCT); C-reactive protein (CRP); erythrocyte sedimentation rate (ESR); white blood cell count, immature granulocyte (IG) count; and multiplex cytokines, including interleukin (IL)1-β (IL1β), IL2, IL4, IL5, IL6, IL9, IL10, IL12p70, IL13, IL17, IL22, tumor necrosis factor-α (TNFα), and interferon-γ (IFNγ). A cytokine bead immunoassay was used to perform simultaneous measurements.The disease involving urinary and respiratory tract constituted 57.5% of all patients. The severity of infection was classified as follows: SIRS patients, n=30; sepsis patients, n=81; and septic shock/severe sepsis patients, n=16. PCT, IL6, and CRP had high area under receiver operation characteristic curve (AUCs) and accuracy, which is as follows: PCT: 0.841, 80.5%; IL6: 0.811, 77.1%; CRP: 0.784, 73.8%, respectively. Severity of sepsis could be discriminated by PCT, IL6, and IL5. Unlike other cytokines, IFNγ had an inverse relation with severity of sepsis. The relationship between cytokine profiles and clinical diagnosis of sepsis was unclear.PCT, IL6, and CRP values could assist diagnosis, and PCT, IL6, and IL5 had discriminative properties for determination of severity of sepsis. IFNγ revealed a distinct inverse relationship with severity of sepsis. As there was no relationship between cytokine profiles and sepsis, further studies are required to develop clinical applications.

AbstractThis study was planned to investigate whether serum α-amylase concentration may be associated with running performance, physiological characteristics and other clinical chemistry analytes in a large sample of recreational athletes undergoing distance running.Forty-three amateur runners successfully concluded a 21.1 km half-marathon at 75%–85% of their maximal oxygen uptake (VOAfter correction for body weight change, significant post-run increases were observed for serum values of alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, bilirubin, creatine kinase (CK), iron, lactate dehydrogenase (LDH), triglycerides, urea and uric acid, whereas the values of body weight, glomerular filtration rate, total and low density lipoprotein-cholesterol were significantly decreased. The concentration of serum α-amylase was unchanged. In univariate analysis, significant associations with running performance were found for gender, VOWe showed that the baseline serum α-amylase concentration significantly and independently predicts distance running performance in recreational runners.
The space of Poincaré type Kähler metrics on the complement of a divisor
Authors: Auvray Hugues 
Published: October 2014

AbstractConsider a divisorDwith simple normal crossings in a compact Kähler manifoldX. It has been known since the work by G. Tian and S. T. Yau that ifKX⁢[D]$K_{X}[D]$is ample there exists onX\D$X\backslash D$a unique Kähler–Einstein metric with cusp singularities along the divisor (implying completeness and finite volume). We show in this article that a Kähler metric in an arbitrary class with constant scalar curvature and singularities analogous to that constructed by Tian and Yau, is unique in this class whenKX⁢[D]$K_{X}[D]$is ample. This we do by generalizing Chen’s construction of approximate geodesics in the space of Kähler metrics and proving an approximate version of the Calabi–Yau theorem, both independently of the ampleness ofKX⁢[D]$K_{X}[D]$.

Data Hiding Based on Improved Exploiting Modification Direction Method and Huffman Coding

Published: October 2014

AbstractThe rapid growth of covert activities via communications network brought about an increasing need to provide an efficient method for data hiding to protect secret information from malicious attacks. One of the options is to combine two approaches, namely steganography and compression. However, its performance heavily relies on three major factors, payload, imperceptibility, and robustness, which are always in trade-offs. Thus, this study aims to hide a large amount of secret message inside a grayscale host image without sacrificing its quality and robustness. To realize the goal, a new two-tier data hiding technique is proposed that integrates an improved exploiting modification direction (EMD) method and Huffman coding. First, a secret message of an arbitrary plain text of characters is compressed and transformed into streams of bits; each character is compressed into a maximum of 5 bits per stream. The stream is then divided into two parts of different sizes of 3 and 2 bits. Subsequently, each part is transformed into its decimal value, which serves as a secret code. Second, a cover image is partitioned into groups of 5 pixels based on the original EMD method. Then, an enhancement is introduced by dividing the group into two parts, namely k1 and k2, which consist of 3 and 2 pixels, respectively. Furthermore, several groups are randomly selected for embedding purposes to increase the security. Then, for each selected group, each part is embedded with its corresponding secret code by modifying one grayscale value at most to hide the code in a (2ki + 1)-ary notational system. The process is repeated until a stego-image is eventually produced. Finally, the χ2 test, which is considered one of the most severe attacks, is applied against the stego-image to evaluate the performance of the proposed method in terms of its robustness. The test revealed that the proposed method is more robust than both least significant bit embedding and the original EMD. Additionally, in terms of imperceptibility and capacity, the experimental results have also shown that the proposed method outperformed both the well-known methods, namely original EMD and optimized EMD, with a peak signal-to-noise ratio of 55.92 dB and payload of 52,428 bytes.

Abstract

Background: Diabetes mellitus is closely related to
pancreas cancer. In this study we aimed to investigate
the effect of hyperglycemia on tumor and inflammation
markers, as well as pancreatic exocrine functions.

Methods: A total of 98 consecutive diabetic patients
with poor glycemic control, and 50 healthy controls were
included in the study. We measured hsCRP, erythrocyte
sedimentation rate (ESR), CA19-9, CEA, amylase and lipase
in addition to routine biochemistry tests, before and after
euglycemia was achieved.

Results: Fasting blood glucose, HbA1c, CA19-9,CEA,
hsCRP, ESR, triglycerides, AST, ALT, GGT, ALP, total
cholesterol and LDL-C levels decreased significantly with
the regulation of glycemic control. Amylase and lipase
levels increased with the regulation of glycemic control.
After glycemic control, CA19-9 and CEA levels were still
higher, whereas amylase and lipase levels were still lower
in the diabetic group compared with the control group.
Basal HbA1c showed significant correlation with CA19-9,
CEA, amylaseand lipase.

Conclusions: We propose to repeat observations of tumor
markers after hyperglycemia is resolved, in order to avoid
unnecessary invasive tests. Our data also suggest that
pancreatic exocrine function was improved with lowering
blood glucose in a short period of time.

Published: October 2014

Abstract
Cardiovascular risk of prediabetes is still
subject to controversies. We analyzed the associations
between insulin resistance, adipokines and incipient
atherosclerosis estimated by intima-media thickness
(IMT) in a cross-sectional study on 122 prediabetic
subjects without clinical signs of atherosclerotic disease.
Homeostasis model assessment of insulin resistance
(HOMA-IR, calculated as fasting insulin × fasting plasma
glucose / 22.5), adiponectin, leptin, leptin-to-adiponectin
ratio, carotid and femoral IMT were evaluated. We also
assessed other parameters related to insulin resistance and
adipokines (HbA1c, anthropometric and lipid parameters),
as they may also influence atherosclerosis. Carotid IMT was
correlated to adiponectin and leptin-to-adiponectin ratio
(all p < 0.05), but not with HOMA-IR or leptin, while
femoral IMT showed no relationship with these factors.
After adjusting for leptin, leptin-to-adiponectin ratio,
triglycerides, HDL-cholesterol, cholesterol-to-HDL ratio,
triglycerides-to-HDL ratio and HbA1c, IMT values became
correlated with HOMA-IR. Adjustment for HOMA-IR induced
the appearance of new correlations between adipokines
and both IMT values. In conclusion, insulin resistance and
adipokines seem related to IMT in prediabetic subjects
without clinical signs of arterial obstruction.
