A taxonomic review of the genus Acanella (Cnidaria: Octocorallia: Isididae) in the North Atlantic Ocean, with descriptions of two new species
Authors: SAUCIER ESPRIT HEESTAND , SAJJADI AUZITA , FRANCE SCOTT C.
Published: September 2017

The deep-sea bamboo coral genus Acanella has a cosmopolitan distribution, is found on hard and soft substrata between 300 and 2875 meters depth, and may be abundant where present. The genus has been the source of taxonomic debate almost since its initial description, and species in the North Atlantic have proven difficult to identify. We examined 145 Acanella colonies collected from across a broad geographic distribution to address morphological variation in the context of genetic differences, focusing on the North Atlantic species, but with a comparison to four Pacific species. We generated DNA sequences for mitochondrial mtMutS and nuclear 18S from ninety-seven Acanella specimens. After combining data from both gene regions, eight concatenated sequences were identified (A–H), six of which are associated with nominal species, while the other two come from taxa that do not match any known species description. The most common sequence (A) is associated with specimens identified as Acanella arbuscula, A. eburnea, and Isidella elongata. We find that morphological characteristics used to differentiate these species are distributed along an intraspecific continuum and that alternate morphologies of A. arbuscula have been identified in collections as different species, with the identity influenced by sampling location. We synonymize A. eburnea with A. arbuscula and discuss confusion with I. elongata. The geographic range of A. arbuscula is expanded. We propose the resurrection of the Mediterranean species A. furcata and describe two new species, A. aurelia sp. nov. and A. scarletae sp. nov. New geographic records and the first SEM images of the Pacific species A. chiliensis, A. rigida, and A. robusta, all described prior to 1907, are also presented.

Published: September 2017

Introduction: The traditional practice of breastfeeding has been negatively affected by the historical trauma experienced by the Canadian Indigenous community. Culturally relevant information and support should be created to enable the communities to reclaim this traditionally revered infant feeding method. The objective of this participatory design study was to work in partnership with Indigenous communities to create an eHealth breastfeeding resource for Indigenous families. Methodology: In partnership with Indigenous mothers and care providers in Ontario, Canada, an eHealth breastfeeding resource was designed based on their recommendations. Once the new resource was created, it was evaluated by additional Indigenous mothers. Results: The participants indicated the resource was culturally relevant and that they liked the content and design. Discussion: Using a participatory design when creating services and programs in partnership with Indigenous communities ensures the creation of resources that meet their needs, are culturally relevant, and align with cultural beliefs.
Polycast: A new paradigm for information-centric data delivery in heterogeneous mobile fog networks
Authors: Lee Eun-Kyu , Lim Jae-Han , Gerla Mario
Published: September 2017

Within the emerging fog network, mobile devices along with local sensors and actuators dynamically form an ad hoc network. As mobile ad hoc networks frequently merge and split in such mobile fog network scenarios, the node addresses must be changed too. This implies that a session may be broken if one of the peers is assigned a new IP address. To overcome this problem, this article proposes a novel structured late-binding address that makes use of node contexts to determine the logical destination group carried in the packet header. The idea is to hide internal mobile ad hoc network details (e.g. addresses) from external sources. The mobile ad hoc network advertises only its own ID and the list of internal contexts. When an external sender transmits a packet to a remote mobile ad hoc network, it must choose first the combination of contexts (i.e. qualifications) that an internal node must present to get the packet. This gives rise to a new data delivery paradigm called polycast. Namely, the physical identities of the destination(s) are determined only when the packet reaches the target mobile ad hoc network. Consequently, the number of destinations can vary from zero (no match) to unicast and multicast depending on the set of contexts. Say, the destinations and routing mode (e.g. unicast, multicast, or broadcast) are determined by the contexts. Simulation models are used to evaluate the scheme and to determine sensitivity to network variables.

Published: September 2017

Advances have been made to improve health care for children with complex health conditions (CCHCs); however, little is known of the needs of these children and their families in the Canadian context. In this article, we describe our Canadian Institutes of Health Research funded Quick Strike protocol, a mixed-methods multisite research project that explored CCHC and their families in two Canadian provinces. The aims were (a) to describe and define CCHC, (b) to understand the needs of CCHC and their families, (c) to identify gaps and barriers to services for this population, and (d) to adapt and test the application of a computerized algorithm to yield information on CCHC. The mixed-methods design was comprised of four components: three qualitative and one quantitative. We describe the components of this project and outline the methods and procedures of data collection and analysis for each component. One of the main sources of data was interviews from 121 stakeholders, which included CCHC and family members, as well as health, social, and education professionals. This Quick Strike project was designed to engage stakeholders and the public with integrated knowledge translation threaded as a core element throughout the research process. Multiple strategies were used to validate and disseminate early findings from the research. As we outline in this article, this research project provided the foundation for one innovative service model of care, NaviCare/SoinsNavi, and spawned a number of additional outcomes such as a secondary analysis of the data to describe interprofessional collaboration for CCHC.
A pilot survey on an understanding of point of care bedside ultrasound (POCUS) among medical doctors in internal medicine: Exposure, perceptions, interest and barriers to training
Authors: Peh Wee Ming , Kang Mei Ling
Published: September 2017

Introduction:

Clinical bedside point-of-care ultrasonography (POCUS) is an important adjunct to history and physical examination. The objective of this pilot survey is to assess the level of exposure, perceptions, interest levels and possible barriers toward training of POCUS in internal medicine.

Methods:

In October 2015, all medical doctors who were working in the Singapore General Hospital Internal Medicine Department were invited to complete a hard-copy printed 27-question Likert-scale survey.

Results:

A total of 124 medical doctors participated in the survey (response rate 82.1%). The proportions of participants who have heard, witnessed, and performed POCUS were 65.6% ( N = 82), 71.2% ( N = 89) and 41.6% ( N = 52), respectively. POCUS was rated highly on usefulness in the practice of internal medicine ( M = 8.74; SD = 1.34). The top three POCUS skills that doctors would like to acquire would be (1) procedural guidance POCUS (70.8%); (2) point-of-care cardiac ultrasound (69%) and (3) lung ultrasound 58.4% (based on percentage ranked first through third). The sample mean of interest in undergoing further training in POCUS is 8.91 (SD = 1.27) (0 = not interested, 10 = very interested). The top three barriers identified were (1) lack of an ultrasound machine ( M = 7.98 SD = 2.28); (2) cost of an ultrasound machine ( M = 7.79 SD = 2.19) and (3) lack of a formal training curriculum ( M = 7.25 SD = 2.08) (0 = not a barrier at all, 10 = severe barrier).

Conclusions:

There is a high level of exposure and interest in POCUS. Doctors perceived bedside POCUS as very useful in the practice of internal medicine. A lack of machine and formal curriculum impedes development of a training program. This pilot survey may serve as a basic needs assessment to an implementation of an internal medicine POCUS training curriculum.

Published: September 2017

Study Design:

Retrospective cohort study.

Objectives:

To determine the incidence of index level fusion following open or minimally invasive lumbar microdiscectomy.

Methods:

We conducted a retrospective review of 174 patients with a symptomatic single-level lumbar herniated nucleus pulposus who underwent microdiscectomy via a mini-open approach (MIS; 39) or through a minimally invasive dilator tube (135). Outcomes of interest included revision microdiscectomy and the ultimate need for index level fusion. Continuous variables were analyzed with independent sample t test, and χ2 analysis was used for categorical data. A multivariate regression analysis was performed to identify predictive factors for patients that required index level fusion after lumbar microdiscectomy.

Results:

There was no difference in patient demographics in the open and MIS groups aside from length of follow-up (60.4 vs 40.03 months, P < .0001) and body mass index (24.72 vs 27.21, P = .03). The rate of revision microdiscectomy was not statistically significant between open and MIS approaches (10.3% vs 10.4%, P = .90). The rate of patients who ultimately required index level fusion approached significance, but was not statistically different between open and MIS approaches (10.3% vs 4.4%, P = .17). Multivariate regression analysis indicated that the need for eventual index level fusion after lumbar microdiscectomy was statistically predicted in smokers and those patients who underwent revision microdiscectomy ( P < .05) in both open and MIS groups.

Conclusions:

Our results suggest a low likelihood of patients ultimately requiring fusion following microdiscectomy with predictors including smoking status and a history of revision microdiscectomy.
Environmental Arsenic Contamination and its Effect on Dental Caries Experience in School Children
Authors: Manju R.  , Hegde Amitha M. , Keshan Anisha
Published: September 2017

Aims and Objectives:

To assess the effect of exposure to arsenic by drinking water and caries prevalence in children.

Material and Methods:

A total of 200 children between 10 to 14 years of age, 100 each from study village (Hutti, Raichur district, Karnataka) and control village (Sanduru, Bellary district, North Karnataka) were included in the study. Water samples from both the villages were analyzed for arsenic levels. Arsenic levels were determined in the hair and nail samples from the subjects to assess chronic arsenic exposure. Caries experience was measured by the DMFT/deft index and the severity of caries was measured by modified ICDAS-II index.

Results:

The mean concentration of arsenic in the study group was found to be 2.44 ppm in the hair samples and 2.72 ppm in the nail samples as compared to 0.12 ppm in both hair and nail samples in the control group. These values were statistically significant ( p < 0.001). The mean DMFT score in the control group was 0.99 and in the study group was 2.45, which was statistically significant ( p < 0.05) using SPSS version 21.

Conclusion:

Chronic arsenic exposure could be a possible cause for the increased caries experience in children in the study group.

Published: September 2017

Purpose

Precision oncology relies on frequent pathologic, molecular, and genomic assessments of tumor tissue to guide treatment selection, evaluate pharmacodynamic effects of novel agents, and determine drug resistance mechanisms. Newer forms of analyses such as drug screens in cell lines and patient-derived xenografts demand increasing amounts of tissue material. It remains unknown how the need for serial biopsies with large numbers of tumor cores relates to tissue yields and biopsy complication rates.

Materials and Methods

In this study, we performed a retrospective analysis of 199 focal liver biopsies performed in 143 patients in the setting of oncologic research protocols (research biopsy group) over a 4-year period at a single-intervention oncology service. Practice patterns and complication rates were compared with those related to 1,522 consecutive biopsies performed in 1,154 patients in whom two cores were obtained for standard clinical management of patients (standard biopsy).

Results

In the research biopsy group, 1,100 tissue cores (average, 5.5 cores per procedure) were harvested and distributed to trial sponsors, internal research laboratories, and pathology services. The complication rate in this cohort was 0.5% for major complications (one of 199) and 1.0% for minor complications managed conservatively (two of 199). In the standard biopsy control group, major complications were observed in 1.4% of procedures (22 of 1,522) and minor complications in 0.2% (three of 1,522). These complication rates were not statistically different.

Conclusion

Harvesting extra tissue cores through coaxial needles during focal liver biopsies does not increase complication rates and yields valuable tissue for additional experimental testing.
Surface transperineal ultrasound and vaginal abnormalities: applications and strengths
Authors: Hamed Soha Talaat , Mansour Sahar Mahmoud
Published: September 2017

The role of ultrasound in the assessment of the female pelvis whether using transabdominal/transluminal approach is well established. Little was reported about the use of the superficial transperineal approach that could provide a full assessment of the lower cervix and vagina, which may be overlooked in the standard examinations. The proximity of the probe to the vagina helps not only the detection of organ abnormalities but also proper characterization and differentiation of vaginal masses. . We discuss the diagnostic role of this superficial ultrasound approach in improving the perception and interpretation of the anatomy and different diseases of the vagina.

Informed consent for percutaneous endoscopic gastrostomy after a stroke: clinicians' perspectives
Authors: Trautner Elaine Elizabeth
Published: September 2017

Dysphagia (difficulty swallowing) is a common outcome for stroke patients, who often require feeding through a percutaneous endoscopic gastrostomy (PEG). Before the procedure, clinicians must take the patient's consent. To fill a gap in existing literature, this research explored the experiences of gastroenterologists and gerontologists who have worked with stroke patients regarding the consent process for post-stroke PEG. The research used a qualitative, hermeneutical and phenomenological design. Data collection involved unstructured interviews with 10 doctors of varied experience, which were transcribed and analysed thematically. Four main themes were found. The first, ‘task vs process’, identified that consent was not a single task or document, but a process with several stages that included consideration of patient needs and physical assessment. The second, ‘collaborative working’, considered the importance of a multidisciplinary approach. The third, ‘process of interaction’, emphasised the necessity of ascertaining patient capacity. The fourth, ‘preparation for consent’, found that some junior doctors were afraid to take patient consent due to lack of knowledge. To improve patient outcomes, junior doctors should not be expected to take consent unless they are fully trained in clinical nutrition, PEG and consent taking.

The visual construction of personal ethos in election posters
Authors: Vigsø Orla
Published: September 2017

When the candidate poster gets to play a more central role in election campaigns, the question of how the candidate is portrayed becomes even more relevant than before. Posters with an image of the candidate must be seen as an attempt at boosting his or her ethos. The picture provides the (potential) voter with an argument for voting for the candidate in question, and this argument clearly has to do with the candidate more than with policies or ideological positions. The size of the portrait, its saliency, shows that the interpretation of personal qualities is the main persuasive feature. But what does ethos actually mean when speaking of portraits of politicians? What are the categories through which ethos can be formulated, and what possible variants exist within each of these categories? One way of categorizing the potentiality of visual representations of ethos is by going back to the Aristotelian definition of the word. In Aristotle, ethos is defined as consisting of three different aspects, or the Aristotelian Trio: phronèsis (competence), arétè (virtue) and eunoia (goodwill), with the addition of two modern features: modesty and youth. This article presents a first attempt at answering the question: how can these aspects be realized visually through the poster?
In Hoc Signo Vinces! Icons, indices and symbols of Italian political parties: 1946–present
Authors: Buscemi Francesco
Published: September 2017

‘In hoc signo vinces!’ is the phrase that the Roman emperor Constantine saw written in the sky next to a cross in 312 AD: a mystical apparition, shortly before the battle of Milvio Bridge, just outside the city of Rome. The phrase means ‘in this sign you will win’, and it was a good omen, as Constantine defeated Massenzio and put an end to his reign. This phrase has been chosen as the title of this study, which concerns the ‘signs’ that political parties adopted in Italy from 1946 to the present, as these parties have created these signs in order to strike a chord with the citizens and win elections. Apart from the historical account of how these symbols have changed, the aim of this study was to find out to what extent these changes may be read as mirrors of broader shifts, especially in terms of negotiation between the old political language and new, de-ideologized visual languages.

‘Beautiful as you feel’: Feminism and post-feminism in Beautiful: The Carole King Musical
Authors: Schuller Julia Elizabeth , Schrader Valerie Lynn
Published: September 2017

This rhetorical analysis examines the production script of Beautiful: The Carole King Musical through the lenses of second-wave feminism, third-wave feminism, and post-feminism. Based on the life of American singer/songwriter Carole King, Beautiful focuses on the triumphs and tribulations of King’s career as a songwriter in the 1960s New York Brill Building, as well as King’s personal life, including her relationship with her spouse/lyricist Gerry Goffin. Through this analysis, we explore how Beautiful’s characters Carole King and Cynthia Weil embody elements of second and third-wave feminism, and suggest that Beautiful: The Carole King Musical conveys an overall empowerment message that is written for a post-feminist audience, given King’s and Weil’s empowerment through individual choices rather than through feminist activism. We conclude that this utopian post-feminist message may be problematic for a twenty-first-century audience in that it fails to acknowledge women’s current career struggles.
In Pursuit of Light War in Libya: Kairotic Justifications of War That Just Happened
Authors: Ohl Jessy J.
Published: September 2017

This essay examines President Barack Obama’s March 28, 2011 address on the war in Libya to theorize a shift in twenty-first-century war rhetoric in which violence is insulated from critique through the numbing of public sensation. In contrast to traditional persuasive appeals aimed at securing collective participation and approval for war, Obama’s oratory is characteristic of “light war,” a mode of conflict that flows more freely by placing few demands on thought, feeling, and attention. I argue that Obama’s rhetoric limits the potential for audiences to sense the material consequences of war through a set of kairotic justifications in which violence is considered “just” in the dual sense that it just ended, and that it is just war, or merely a banal and quotidian version of conflict. After unpacking the anesthetizing features of Obama’s discourse, I conclude by addressing the prospects of resistance given the compressed interval for public thought and feeling to interrupt violent practices.
Operation Coffeecup: Ronald Reagan, Rugged Individualism, and the Debate over “Socialized Medicine”
Authors: Onge Jeffrey St.
Published: September 2017

In 1961, the American Medical Association (AMA) funded a persuasive campaign called Operation Coffeecup. The campaign, which was designed to defeat Medicare, featured a speech by a young Ronald Reagan outlining the dangers of “socialized medicine.” The speech was recorded on a long-play record and distributed to the Women’s Auxiliary of the AMA, a group primarily composed of the wives of doctors who were instructed to write seemingly spontaneous letters to Congress detailing their opposition to the program. This essay investigates Operation Coffeecup mainly through a rhetorical analysis of Reagan’s speech. I argue that “socialized medicine” drew upon a problematic articulation of American culture that privileges the individual at the expense of the larger community. I conclude by discussing the thread of individualism that has persisted in the United States from the pre-Depression era mythos of rugged individualism to neoliberal discourses that shape debates about health policy today.

Esta pesquisa objetivou avaliar os conhecimentos e envolvimento dos estudantes do ensino médio público (15-20 anos) da cidade de Mãe D’Água, Paraíba, relacionados às plantas medicinais e promover a construção de saberes nessa área por meio de uma prática de ensino. O estudo teve três momentos distintos: aplicação de questionário constituído 9 afirmativas estruturadas segundo o modelo da escala de Likert e mais 6 perguntas; vivência prática didática com os alunos e; reaplicação do questionário. Os alunos possuíam pouco conhecimento sobre A etnobotânica, plantas medicinais e o seu uso. Entretanto, após a vivência didática, se observou aumento significativo desse conhecimento, tais como conceituar corretamente a Etnobotânica e o que são plantas medicinais. Os conhecimentos sobre plantas medicinais foram adquiridos, principalmente, dos avós. As folhas é a parte que eles mais usam para fins medicinais. Antes da prática, eles 24,5% acreditavam que as plantas medicinais não causavam danos à saúde, 67,3% consideravam os seus efeitos moderados. Após a prática didática, esses percentuais modificaram-se para 8,2% e 51%, respectivamente. A prática didática foi eficaz para mediar e melhorar esse conhecimento. Os alunos, antes e após a prática didática, consideraram importante o estudo das plantas medicinais na disciplina de Biologia para informar sobre seus diferentes aspectos, tais como: ecológico, botânico (morfológico e taxonômico). É veemente a necessidade da inserção do ensino sobre plantas medicinais no currículo escolar, para que haja a construção do saber e promoção da valorização e uso dessas plantas presentes na comunidade em que os estudantes vivem.

Published: September 2017

A poluição dos recursos hídricos é um dos fatores que provoca diminuição da disponibilidade de água de boa qualidade e a crescente utilização de técnicas avançadas de tratamento. O presente trabalho aborda o uso de um material adsorvente de origem vegetal, produzido com tratamento térmico e ativação química com hidróxido de sódio (carvão ativado) e sem tratamento térmico (in natura) a partir dos frutos de pinheiro-da-praia (Casuarina equisetifolia) para o tratamento avançado de águas e efluentes contaminados com óleos e graxas por adsorção, adequando-o aos padrões de descarte estabelecido pela legislação vigente ou ao reuso. Para tanto, foram estudadas as isotermas de adsorção, variando-se a temperatura e a massa do bioadsorvente, comparando-se sua capacidade adsortiva com a de outros adsorventes vegetais, sendo um deles um produto comercial. Foi feito também um estudo estatístico para otimização do processo. O bioadsorvente in natura apresentou maior poder de adsorção em relação ao carvão ativado, nas mesmas condições experimentais, conferindo-lhe o status de um bom adsorvente para o tratamento de efluentes e águas por adsorção.

Cryptographic identification protocols enable a prover to prove its identity to a verifier. A subclass of such protocols are shared-secret challenge-response identification protocols in which the prover and the verifier share the same secret and the prover has to respond to a series of challenges from the verifier. When the prover is a human, as opposed to a machine, such protocols are called human identification protocols. To make human identification protocols usable, protocol designers have proposed different techniques in the literature. One such technique is to make the challenges

This paper predict the effect of the object's morphology on the final accuracy of the scanned data, for the case of contactless
laser scanning. On the basis of the scanned objects morphology, two important process parameters are specified namely
scanning angle and distance of the laser from the part surface. Experiments have been performed with different scanning
conditions using full factorial design. An analytical prediction model for determining the standard deviation of the final
surface is developed in terms of the aforesaid scanning parameters using response surface methodology (RSM). Furthermore,
the optimal scanning parameters are predicted after comparing two almost unexplored nature inspired algorithms i.e. Whale
Optimization Algorithm (WOA) and Moth-Flame Optimization (MFO). Finally, two realistic non-trivial case studies are
considered for validation of the proposed methodology. The result shows that the standard deviation of the final reverse
engineered models significantly reduced by 21.6% and 13.77%. The adopted methodology provides the optimal
combination of morphological scanning process parameters with a considerable reduction in standard deviation for final scanned
surface models.
Von Joburg nach Gauteng: Transformation der City of Gold zur Global City Region?
Authors: Haferburg Christoph , Oßenbrügge Jürgen
Published: September 2017

Johannesburg wird in der World- und Global-City-Forschung zumeist als einzige Metropole Afrikas mit globaler Bedeutung eingeordnet. Die Agglomeration verdankt ihre Existenz der internationalen Kapitalinvestition in den Goldbergbau, war aber in ihrer 130jährigen Geschichte vielfachen Transformationen unterworfen. Seit dem Ende der Apartheid bestimmen globale Einbindung, Tertiärisierung sowie Flächen- und Bevölkerungswachstum das Bild. Der vorliegende Text analysiert sowohl die Verflechtungen mit und Abhängigkeiten von globalen Dynamiken als auch die Persistenzen und Veränderungen der national und lokal angelegten urbanen Entwicklungspfade. Ausgangspunkt sind die Global-City- bzw. Global-City-Region- und Global-Value-Chain-Debatten, inklusive der darauf bezogenen Kritik. Die Verschiebung der Perspektive von Johannesburg auf Gauteng als global eingebundene „Megaregion“ bildet die empirische Rückbindung.
Photosystem II Heterogeneity and Long-Term Acclimation of Light-Harvesting
Authors: Mäenpää Pirkko , Andersson Bertil

The main chlorophyll a/b protein complex of the chloroplast thylakoid membrane is organized into two subpopulations; one inner which is tightly bound to the photosystem II core and one outer which is bound more loosely or peripherally. In this study, changes in the LHC II com position due to long-term light acclimation were analyzed and quantified in spinach thylakoids and isolated stroma lamellae vesicles. The results show that; photosystem II located in the appressed thylakoid regions (α-centres) which have a relatively large antenna size, contains both the inner and outer LHC II with a predominance of the latter (58-70%). At low light the antenna size o f the α-center becomes larger due to a specific increase of the outer pool o f LHC II. The antenna size of photosystem II in the stroma thylakoids (β-centres) is smaller and contains mainly or only the inner LHC II pool. In contrast to the α-centres the β-centres centres do not undergo adaptive changes in their size in response to long-term changes in the light intensities.

Published: September 2017

In the present study the effect of TBTQ on PS II and its mutual interaction with DCMU was analyzed by measurements of the oxygen yield oscillation pattern and of DCMU binding. It was found: 1)TBTQ in its reduced form is able to induce the reduction of Dox which gives rise to an accelerated decay of S2 and S3 of the wateroxidizing complex. 2) Triton X-100 treatment used for isolation of PS II membrane fragments does not significantly affect the lateral mobility of p lastoquinone within the membrane. TBTQ bound to the thylakoid membrane does not enhance the electron pool capacity in PS II membrane fragments. 3) Preincubation of thylakoids with TBTQ diminishes the blockage of O2-evolution by DCMU significantly. In correspondence with previous findings [18, 19] the effect strongly depends on the order of addition of TBTQ and DCMU . 4) Excitation with a single saturating flash causes enhanced DCMU binding in TBTQ pretreated samples leading to the inhibition of flash induced oxygen evolution. The rate of the latter process depends on the DCMU concentration. 5) In thylakoids pretreated in the d ark with TBTQ the oxygen yield of the 3rd flash slowly declines as a function o f dark incubation time at constant DCMU concentration. Based on the above mentioned findings it is inferred that a mutual interaction between TBTQ and DCMU takes place at the PS II acceptor side. Two alternative mechanisms are discussed: i) TBTQ tightly (covalently?) bound at the QB-site (or very close to it) is modified in its function by DCMU via structural effects (allosteric type), or ii) there occurs a TBTQ /DCMU exchange that is fast in the light and slow in the dark.
Stigmatellin Affects Both Hemes of Cytochrome b in Cytochrome b6f/bc1-Complexes

Stigmatellin causes spectral changes of both hemes of cytochrome b or b6 in cytochrome bc1/b6f-complexes. It also affects the redox potentials of all three hemes, including cytochrome c l and f, in addition to the dramatic rise of the redox potential it exerts on the Rieske FeS-center. We conclude that stigmatellin changes the overall conformation of the complexes.
5'-Monohydroxyphylloquinone as a Component of Photosystem I
Authors: Ziegler Karl , Maldener Iris , Lockau Wolfgang
Published: September 2017

Thylakoids and photosystem I (PS I) preparations from Euglena gracilis and from the cyanobacterium Anacystis nidulans were analyzed for their prenylquinone content. Both organisms contained 5 '-monohydroxyphylloquinone as the dominant quinone of PS I, and not phylloquinone as other organisms. A stoichiometry of about two 5 '-monohydroxyphylloquinone per P700 (the primary electron donor of PS I) was determined for A nacystis. However, both the PS I preparation and the thylakoids from Euglena contained only one 5 '-monohydroxyphylloquinone per P700. Phylloquinone and an unidentified naphthoquinone were present in trace amounts.
Diesel Soot — Catalyzed Production of Reactive Oxygen Species: Cooperative Effects with Bisulfite
Authors: Hippeli S. C. , Elstner E. F.
Published: September 2017

The fragmentation of KMB (4-(methylthio)-2-oxobutyric acid) as an indicator reaction for the production of strong oxidants is catalyzed by diesel soot particles in the light. This reaction operates also in the dark and can be strongly stimulated by the addition of sulfite. The cooperative activity of diesel soot particles (DP) and sulfite also bleaches the carotenoid crocin. This molecule represents a model for both the groups of plant pigments as well as polyene structures embedded as flexible backbones in cellular membranes. Enhanced chemiluminescence generated by linolenic acid in the presence of either ter/-butylhydroperoxide or hydrogenperoxide is detected in the presence of both DP and HSO3
-. Luminescence originates from singlet oxygen or chemically excited molecules such as triplet ketones and is thus a valuable indicator for peroxidation of lipids involved in membrane damage. All reactions were inhibited by SOD (superoxide dismutase) whereas catalase had no effect.
Professional Dissonance
Authors: Harkness Geoff , Levitt Peggy
Published: September 2017

This article examines the working lives of creative-class professionals in the Global South using two case studies: university educators and museum professionals employed in Qatar. A small country on the Arabian Peninsula, Qatar is an ideal site for the study of professionals in a developing yet authoritarian nation. We argue that the cultural attributes of the professorial and curatorial communities, including creativity, autonomy, and intellectual freedom, are in conflict with the authoritarian political context, giving rise to professional dissonance. Professional dissonance occurs when the norms, values, and ideas embraced by a particular occupational group conflict with the norms, values, and ideas in the settings in which they work. To cope, university educators and museum professionals turn to five strategies—resistance, subversion, submission, conversion, and exit—although variations in the content and institutional structures of their work lead each group to deploy them in somewhat different ways. These strategies may be replicated in other contexts of high professional dissonance, caused by authoritarianism or otherwise.
Molecular cartography of mutational landscapes in melanomas

Published: September 2017

Understanding the origins of mutations in genes and how these give rise to tumors is a central problem in biology. A new study in The EMBO Journal has produced a 3‐dimensional map of DNA damage induced by sunlight, a pervasive carcinogen, and found that genes on the periphery, located near the nuclear lamin, are more prone to damage than those in the interior of the nucleus. In addition, high levels of damage showed a remarkable correlation with driver mutations in melanoma.
Pathological processes and therapeutic advances in radioiodide refractory thyroid cancer

Published: September 2017

While in most patients with non-medullary thyroid cancer (TC), disease remission is achieved by thyroidectomy and ablation of tumor remnants by radioactive iodide (RAI), a substantial subgroup of patients with metastatic disease present tumor lesions that have acquired RAI resistance as a result of dedifferentiation. Although oncogenic mutations inBRAF,TERTpromoter andTP53are associated with an increased propensity for induction of dedifferentiation, the role of genetic and epigenetic aberrations and their effects on important intracellular signaling pathways is not yet fully elucidated. Also immune, metabolic, stemness and microRNA pathways have emerged as important determinants of TC dedifferentiation and RAI resistance. These signaling pathways have major clinical implications since their targeting could inhibit TC progression and could enable redifferentiation to restore RAI sensitivity. In this review, we discuss the current insights into the pathological processes conferring dedifferentiation and RAI resistance in TC and elaborate on novel advances in diagnostics and therapy to improve the clinical outcome of RAI-refractory TC patients.
