Authors: Cepeda Javier , Pérez‐Yáñez Sonia , Beobide Garikoitz , Castillo Oscar , García Jose Ángel , Luque Antonio 
Published: June 2015

AbstractInvited for the cover of this issue is the group of Oscar Castillo at the University of the Basque Country (UPV/EHU) in Bilbao, Spain. The cover image shows the colors emitted by polycrystalline samples of a series of 3D coordination compounds comprising yttrium(III) metal ions and pyrimidine‐4,6‐dicarboxylato and oxalato ligands when they are doped with europium(III) and terbium(III) ions. The color of the emission can be tuned by changing the amount of doping, varying the excitation wavelength, and/or monitoring the dehydration/rehydration of the channels.

AbstractA concise noncatalytic synthetic approach to 2‐ and 3‐substituted 4,4′‐dicyanobiphenyls by applying terephthalonitrile dianion 12– as para‐cyanophenylating reagent for neutral benzonitriles is described. Neutral participants are varied to reveal the scope of applicable substrates and to evaluate the electronic and structural factors governing the regioselectivity and efficiency of the cross‐coupling. Benzonitriles substituted with Me, OMe and F provide the corresponding dicyanobiphenyls in good yields. The regularities in the reactivities are interpreted in terms of a reaction scheme involving the intermediacy of a charge‐transfer complex between 12– and benzonitrile, which transforms into a dimeric dianion either through a heterolytic pathway and/or by successive single electron transfer and recombination of the primary generated radical anions. Quantum chemical calculations of the structure and energy of the principal reaction intermediates match the experimental data. CV measurements of the new dicyanobiphenyls are also included.

AbstractCancer chemotherapy remains one of the preferred therapeutic modalities against malignancies despite its damaging side effects. An expected outcome while utilizing chemotherapy is apoptosis induction. This is mainly regulated by a group of proteins known as the Bcl‐2 family, usually found within the endoplasmic reticulum or the mitochondria. Recently, these proteins have been located in other sites and non‐canonic functions have been unraveled. Bik is a pro‐apoptotic protein, which becomes deregulated in cancer, and as apoptosis is associated with oxidative stress generation, our objective was to determine the subcellular localization of Bik either after a direct oxidative insult due to H2O2, or indirectly by cisplatin, an antineoplastic agent. Experiments were performed in two human transformed mammary gland cell lines MDA‐MB‐231 and MCF‐7, and one non‐tumorigenic epithelial cell line MCF‐10A. Our results showed that in MCF‐7, Bik is localized within the cytosol and that after oxidative stress treatment it translocates into the nucleus. However, in MDA‐MB‐231, Bik localizes in the nucleus and translocates to the cytosol. In MCF10A Bik did not change its cellular site after either treatment. Interestingly, MCF10A were more resistant to cisplatin than transformed cell lines. This is the first report showing that Bik is located in different cellular compartments depending on the cancer stage, and it has the ability to change its subcellular localization in response to oxidative stress. This is associated with increased sensitivity when exposed to toxic agents, thus rendering novel opportunities to study new therapeutic targets allowing the development of more active and less harmful agents.

Bodies in Times of War: A Comparison of Hijikata Tatsumi and Mary Wigman's Use of Dance as Political Statement
Authors: Calamoneri Tanya 
Published: June 2015

How does the representation of bodies change in times of war? How can dance be political activism? This paper considers the dances of Hijikata Tatsumi and Mary Wigman in relation to their experiences of war, and explores their use/representation of the body as a political statement. In both cases, these artists sought to use dance to rescue the body from its subjugated social standing.Mary Wigman's dance technique is influenced by Germankorperkultur, and had its birth in her work with Rudolph Laban and at the natural paradise of Hellerau. Wigman admired Nietzsche's desire to rescue the body from “despisers of the body,” who saw the physical body as an obstacle that must be denied in order for the soul to reach salvation. For Wigman, the “sensuous dancing body” that Nietzsche referred to inZarathustra“became the vehicle to an authentic life.”Hijikata's idea of dancers as “lethal weapons that dream” offered a view of bodies that were aware of personal agency and chose to step outside of usefulness for the elusive “advancement” of society. He explains, “in this sense my dance, based on human self-activation … can naturally be a protest against the ‘alienation of labor’ in capitalist society.” Douglass Slaymaker's writing on post-war Japanese literature frames Hijikata's sentiment in the time: images of body asnikutai[flesh] were considered counterhegemonic because they defied the notion that the individual body belonged to the national body. Hijikata redirected the body's sacrifice away from productivity and toward the creation of art.

AbstractDietary fats and sodium are both palatable and are hypothesized to synergistically contribute to ingestive behavior and thereby obesity. Contrary to this hypothesis, C57BL/6J mice fed a 45% high fat diet exhibited weight gain that was inhibited by increased dietary sodium content. This suppressive effect of dietary sodium upon weight gain was mediated specifically through a reduction in digestive efficiency, with no effects on food intake behavior, physical activity, or resting metabolism. Replacement of circulating angiotensin II levels reversed the effects of high dietary sodium to suppress digestive efficiency. While the AT1 receptor antagonist losartan had no effect in mice fed low sodium, the AT2 receptor antagonist PD-123,319 suppressed digestive efficiency. Correspondingly, genetic deletion of the AT2 receptor in FVB/NCrl mice resulted in suppressed digestive efficiency even on a standard chow diet. Together these data underscore the importance of digestive efficiency in the pathogenesis of obesity and implicate dietary sodium, the renin-angiotensin system and the AT2 receptor in the control of digestive efficiency regardless of mouse strain or macronutrient composition of the diet. These findings highlight the need for greater understanding of nutrient absorption control physiology and prompt more uniform assessment of digestive efficiency in animal studies of energy balance.

Published: June 2015

Purpose– The purpose of this paper is to determine perceived barriers to utilization of mental health services among adults in Dodoma Municipality, Tanzania. To improve the use of mental health services, identifying related perceived barriers is a key step.Design/methodology/approach– A concurrent mixed method model was used. Data were collected through face-to-face interviews (n=152) using a structured survey questionnaire. In addition in-depth interviews were conducted (n=10). The quantitative data were analyzed by using Epi info version 2002. Content analysis was used for analyzing qualitative data.Findings– The majority of respondents opted to use modern mental health facilities for mental illness treatment. They also used spiritual healing and other forms traditional methods including herbal medicines. The most frequently identified causes of mental illness were: drug abuse, being cursed and witchcraft, demons or evil spirit possession. The reported significant perceived barriers were stigma, economic, lack of transport, witchcraft, lack of awareness of mental health services, unemployment, and negative believes about professional cure.Originality/value– The option for mental health service utilization is influenced by the existing barriers on community and clients’ perception. There is a need for mental health professionals and policy makers to integrate mental health into primary care. Mutual sharing of knowledge between mental health professionals and tradition healers is warranted. Further research on the attitudes toward mental health professional services and on effectiveness of traditional healers’ services is indicated.

ObjectivesDepression in the context of bipolar disorder (BD) is often misdiagnosed as unipolar depression (UD), leading to mistreatment and poor clinical outcomes. However, little is known about the similarities and differences in interhemispheric functional connectivity between BD and UD.MethodsPatients with bipolar II disorder (n = 36) and UD (n = 32) during a depressive episode as well as 40 healthy controls underwent resting‐state functional magnetic resonance imaging. The functional connectivity between any pair of symmetric interhemispheric voxels (i.e., functional homotopy) was measured by voxel‐mirrored homotopic connectivity (VMHC).ResultsThe three groups showed significant VMHC differences in the posterior cingulate cortex (PCC), fusiform and lingual gyrus, anterior lobe of the cerebellum (CeAL), and posterior lobe of the cerebellum (CePL). In the BD group, the VMHC decreases in the fusiform/lingual gyrus, CeAL, and CePL were shown relative to controls. In the UD group, the VMHC decreases in the PCC, fusiform/lingual gyrus, and CePL were shown relative to controls. No regions of increased VMHC were detected in either patient group. There was no significant difference in the VMHC values in any brain region between the BD group and the UD group.ConclusionsDepressive episodes in BD and UD have similar impairments of interhemispheric coordination, which might imply an overlap in the neuropathology of depression.

AimsTo evaluate the relationship between left atrial (LA) structure and deformation obtained by two‐dimensional speckle tracking echocardiography (2DSTE): peak longitudinal systolic strain (LAs), peak longitudinal systolic strain rate (LAS‐SR), peak longitudinal early diastolic strain rate (LAE‐SR), peak longitudinal late diastolic strain rate (LAA‐SR), and sleep‐disordered breathing (SDB) estimated by means of apnea–hypopnea index (eAHI).MethodsThirty‐two individuals with ischemic heart disease (IHD) and impaired left ventricular ejection fraction (EF < 50%) were included in the study. LA function was assessed using 2DSTE. eAHI index was calculated by means of the 24‐hour ambulatory Holter electrocardiogram monitoring. Patients were categorized into two subgroups: SDB group (eAHI ≥ 15; n = 15) and non‐SDB group (eAHI < 15; n = 17).ResultsAll 2DSTE parameters were decreased in the SDB group: LAS‐SR (0.90 [0.60–1.25] 1/sec vs. 1.25 [1.00–1.27] 1/sec, P = 0.043), LAE‐SR (−0.76 ± 0.49 1/sec vs. −1.18 ± 0.55 1/sec, P = 0.033), and LAA‐SR (−1.26 ± 0.71 1/sec vs. −1.48 ± 0.75 1/sec, P = 0.049). The eAHI was negatively correlated with LA reservoir function: LAS (r = −0.53, P = 0.002) and LAS‐SR (r = −0.47, P = 0.006), while it is positively correlated with LAE‐SR (r = 0.67, P < 0.001) and LAA‐SR (r = 0.46, P = 0.009). Moreover, SDB severity was an independent predictor of impaired LA compliance (P = 0.016) and conduit function (P = 0.002) in multivariate linear regression model, even after adjustment for age, BMI, gender, LV systolic (EF), and diastolic (E/e′) function and comorbidities.ConclusionsLA dysfunction and remodeling assessed using 2DSTE in patients with impaired systolic LV function, and IHD is influenced by the severity of sleep apnea independently from LV function.

AbstractObjectivesTo assess and compare the knowledge of rugby players regarding first‐aid measures for dental injuries.MethodsA cross‐sectional study was conducted at rugby tournaments in 2009 and 2010 on players aged 16 and over. Convenient sampling was performed. A total of 456 self‐administered questionnaires were returned. Data collected were analysed using SPSS 21. Descriptive analysis was undertaken for the demographic data. The subjects were classified according to their experience of sustaining each type of injury. Cross‐tabulation and chi‐square tests were carried out to compare the responses. When the expected cell count was less than five, Fisher's exact test was used. The level of significance was set at P < 0.05.ResultsThe prevalence of self‐reported dental injuries was as follows: tooth fracture (19.3%), luxation (6.6%) and avulsion (1.1%). Significant differences were found, whereby 52.2% of those who had no history of tooth fracture were more likely to seek immediate treatment (P < 0.001), whereas 42% of those who previously experienced tooth fracture claimed that they would only visit a dentist if they experienced pain (P = 0.001). Management of luxation and avulsion did not differ significantly between the groups. However, about half of those who did not have a history of tooth avulsion admitted to not knowing the correct answer, while three of five casualties would keep the tooth iced.ConclusionsKnowledge of the management of tooth fracture and storage medium differs between previous casualties and non‐casualties. Overall, knowledge of dental trauma management was insufficient, suggesting the need to educate and train the players.
Contrasting effects of climate on juvenile body size in a Southern Hemisphere passerine bird

Published: June 2015

AbstractDespite extensive research on the topic, it has been difficult to reach general conclusions as to the effects of climate change on morphology in wild animals: in particular, the effects of warming temperatures have been associated with increases, decreases or stasis in body size in different populations. Here, we use a fine‐scale analysis of associations between weather and offspring body size in a long‐term study of a wild passerine bird, the cooperatively breeding superb fairy‐wren, in south‐eastern Australia to show that such variation in the direction of associations occurs even within a population. Over the past 26 years, our study population has experienced increased temperatures, increased frequency of heatwaves and reduced rainfall – but the mean body mass of chicks has not changed. Despite the apparent stasis, mass was associated with weather across the previous year, but in multiple counteracting ways. Firstly, (i) chick mass was negatively associated with extremely recent heatwaves, but there also positive associations with (ii) higher maximum temperatures and (iii) higher rainfall, both occurring in a period prior to and during the nesting period, and finally (iv) a longer‐term negative association with higher maximum temperatures following the previous breeding season. Our results illustrate how a morphological trait may be affected by both short‐ and long‐term effects of the same weather variable at multiple times of the year and that these effects may act in different directions. We also show that climate within the relevant time windows may not be changing in the same way, such that overall long‐term temporal trends in body size may be minimal. Such complexity means that analytical approaches that search for a single ‘best’ window for one particular weather variable may miss other relevant information, and is also likely to make analyses of phenotypic plasticity and prediction of longer‐term population dynamics difficult.
Medical use of cannabis: an addiction medicine perspective

Published: June 2015

AbstractThe use of cannabis for medical purposes, evident throughout history, has become a topic of increasing interest. Yet on the present medical evidence, cannabis‐based treatments will only be appropriate for a small number of people in specific circumstances. Experience with cannabis as a recreational drug, and with use of psychoactive drugs that are prescribed and abused, should inform harm reduction in the context of medical cannabis.

Published: June 2015

AbstractBackgroundIt is difficult to diagnose autism spectrum disorder (ASD) in people with a combination of intellectual and sensory disabilities because of overlap in behaviour. The ASD typical behaviours of people with combined intellectual and sensory disabilities are often caused by their disabilities and not by ASD. Current diagnostic tools are inadequate to differentiate between people with and without ASD when they have these combined disabilities, because tools lack norms for this population or are subjective, indirect or unable to adapt to the variety of disabilities that these people may have. Because giving a correct diagnosis is necessary for treatment and support, a new observational tool was developed to diagnose ASD in people with multiple disabilities, observation of autism in people with sensory and intellectual disabilities (OASID).MethodObservation of autism in people with sensory and intellectual disabilities was tested on 18 participants with moderate to profound intellectual disabilities, one or dual sensory impairment, with and without ASD. Two independent experts diagnosed these participants as well in order to test the psychometric properties and differentiating abilities of OASID.ResultsObservation of autism in people with sensory and intellectual disabilities showed high inter‐rater reliability, internal consistency of scales and content and construct validity. OASID could differentiate people with and without ASD without overlap.ConclusionsObservation of autism in people with sensory and intellectual disabilities could differentiate people with intellectual disabilities combined with sensory impairments, who clearly had or did not have signs of ASD. People with unclear signs of ADS scored in between those two groups with regard to their OASID scores. Psychometric properties of OASID are promising.
The Indirect Future Influence of the EU on Post‐communist Family Policy
Authors: Saxonberg Steven 
Published: June 2015

AbstractTheorists of Europeanization expected the EU to have the greatest influence on post‐communist countries during the period of negotiation to join the EU as the EU had the greatest possibilities of pressuring the post‐communist countries to make reforms before they joined, on the grounds that it could threaten to prevent these countries from joining unless they met certain conditions. However, in the case of family policy, the EU had very little direct influence on the post‐communist countries. These countries had already long since met the minimum conditions for maternity leaves, while they simply ignored the Barcelona goal of providing day care for one‐third of children aged under three. When the Czech Republic had the EU presidency, its Prime Minister openly stated that the post‐communist countries would have never agreed to the Barcelona goals if they had been members at the time the agreement was made. The one area in which the EU has had some direct influence is in its demands to make laws gender neutral. Thus, the ‘extended maternity leaves’ that follow the more generously paid maternity leaves had to be transformed into ‘parental leaves’ that are open to men and guarantee men the right to get their job backs afterwards. However, since the leave benefits are a low flat‐rate in most of the countries, very few men have gone on leave; so in practice they have remained as ‘extended maternity leaves’ more than parental leaves.Nevertheless, the EU has had great indirect influence on family policy in that by requiring ‘gender mainstreaming’, all the post‐communist countries have had to set up commissions that examine law proposals from a gender equality perspective. This in turn has given the notion of ‘gender equality’ much more legitimacy in the public eye, as the mass media has felt pressure to report more on these issues. After discussing the actual changes in policies in two post‐communist countries (the Czech Republic and Poland), this article goes on to analyze the discourse on feminism in the main daily newspapers, and it shows that before accession the newspapers were rather hostile towards feminism, while afterwards they have become much more accepting of the term. This more open view towards ‘feminism’ meant that it would be easier for future reforms in family policy to be made which could be more supportive of gender equality. Thus, Poland has recently reformed its parental leaves in a manner that gives men greater incentives to share in the leaves, and an openly feminist activist, who wants fathers to share in parental leaves, has recently become Minister for Labour and Social Affairs in the Czech Republic. The EU did not have any direct influence on these developments, but by forcing countries to have gender equality commissions, the EU contributed to making ‘feminism’ more acceptable, which in turn made it easier for feminists to become ministers in charge of social policy, who could carry out reforms long after the countries had joined the EU.
