Abstract
The redox behaviour of Tc(VII)/Tc(IV) was investigated within the pH
c
range 2–14.6 in (0.5 M
and 5.0 M) NaCl and (0.25 M, 2.0 M and 4.5 M) MgCl2 solutions in the
presence of different reducing agents (Na2S2O4, Sn(II), Fe(II)/Fe(III), Fe powder) and macroscopic
amounts of Fe minerals (magnetite, mackinawite, siderite: S/L = 20–30 g L
–1). In the first group of samples, the
decrease of the initial Tc concentration (1 · 10
–5 M, as Tc(VII)) indicated the reduction to Tc(IV) according to
the chemical reaction TcO4

–
+ 4H++ 3e
–
↔ TcO2 · 1.6H2O(s) + 0.4H2O. Redox speciation of Tc in the aqueous phase was further confirmed by solvent extraction. A good agreement is obtained
between the experimentally determined Tc redox distribution and thermodynamic calculations based on NEA–TDB (Nuclear Energy Agency,
Thermochemical Database) and ionic strength corrections by SIT or Pitzer approaches. These observations indicate that experimental
pH
c
and E
h values in buffered systems can be considered as reliable parameters to predict the redox behaviour of
Tc in dilute to highly concentrated NaCl and MgCl2 solutions. E
h of the system and aqueous concentration of
Tc(IV) in equilibrium with TcO2 · 1.6H2O(s) are strongly affected by elevated ionic strength, especially in the case of
4.5 M MgCl2 solutions. In such concentrated brines and under alkaline conditions (pH
c
= pH
max
∼ 9), kinetics play a relevant role and thermodynamic equilibrium for the system Tc(IV)(aq) ↔ Tc(IV)(s) was not attained from oversaturation conditions within the timeframe of this study (395 days). Tc(VII) is reduced to
Tc(IV) by magnetite, mackinawite and siderite suspensions at pH
c
= 8 – 9 in concentrated NaCl and MgCl2
solutions. Sorption is very high in all cases (R
d ≥ 103 L kg
–1), although R
d values are
significantly lower in 4.5 M MgCl2 solutions. XANES (X-ray absorption near edge spectroscopy) evaluation of these
samples confirms that Tc(VII) is reduced to Tc(IV) by Fe(II) minerals also in concentrated NaCl and MgCl2 brines.
Expression ofMTAPInhibits Tumor-Related Phenotypes in HT1080 Cells via a Mechanism Unrelated to Its Enzymatic Function

Published: November 2014

AbstractMethylthioadenosine Phosphorylase (MTAP) is a tumor suppressor gene that is frequently deleted in human cancers and encodes an enzyme responsible for the catabolism of the polyamine byproduct 5′deoxy-5′-methylthioadenosine (MTA). To elucidate the mechanism by which MTAP inhibits tumor formation, we have reintroduced MTAP into MTAP-deleted HT1080 fibrosarcoma cells. Expression of MTAP resulted in a variety of phenotypes, including decreased colony formation in soft-agar, decreased migration, decreased in vitro invasion, increased matrix metalloproteinase production, and reduced ability to form tumors in severe combined immunodeficiency mice. Microarray analysis showed that MTAP affected the expression of genes involved in a variety of processes, including cell adhesion, extracellular matrix interaction, and cell signaling. Treatment of MTAP-expressing cells with a potent inhibitor of MTAP’s enzymatic activity (MT-DADMe-ImmA) did not result in a MTAP− phenotype. This finding suggests that MTAP’s tumor suppressor function is not the same as its known enzymatic function. To confirm this, we introduced a catalytically inactive version of MTAP, D220A, into HT1080 cells and found that this mutant was fully capable of reversing the soft agar colony formation, migration, and matrix metalloproteinase phenotypes. Our results show that MTAP affects cellular phenotypes in HT1080 cells in a manner that is independent of its known enzymatic activity.

In the history of Indonesian politics, the institutionalization of the presidential system has experienced ups and downs. The presidential system has had its own style and character under each regime. The main factor behind this relates to the varying nature of the political systems and patterns of leadership. Since the reformasi era and the amendment of the 1945 Constitution, however, the system has experienced a ‘purification’. During the period of president Habibie, the system was not implemented thoroughly, because of the transitional nature of the government. The embryo of a presidential system begun to emerge with the 1999 general election. The purification was marked by two fundamental changes. Firstly, there was the strengthening between the legislative and the executive. Secondly, there was the restriction of the period in which a president could only be elected for two periods. With these amendments, the opportunities open to an incumbent president during the reformasi era have been restricted by the law. The presidential term makes the periods for presidents and vice-presidents more fixed.DOI: 10.15408/sdi.v21i2.1041
Kembalinya Konservatisme Islam Indonesia
Authors: Wahid Din 
Published: November 2014

Martin van Bruinessen, ed, Contemporary Development in Indonesian Islam, Explaining the “Conservative Turn”, Singapore: Institute of Southeast Asian Studies, 2013, pp. 240 + xxxiv.Contemporary Developments in Indonesian Islam: Explaining the ‘Conservative Turn’ consists of four articles analyzing conservative currents among Muslims in Indonesia. The book’s first two articles deal with established Muslim organizations, namely the Council of Indonesian ‘Ulama (MUI) and Muhammadiyah, while the other two discuss radical Islamic movements in the regions of South Celebes and Solo, Central Java. Written by van Bruinessen, the book examines why the conservative trend has reemerged in Indonesian Islam. The author provides readers with two theories. Firstly, he argues that a decline in the influence of liberal thought has accompanied the democratization process. Secondly, he identifies an increase of Middle Eastern influence to Indonesia through alumni. This work shows that conservatism is not only apparent in radical Islamic movements that have emerged during the Reformation era but also present in well-established organizations such as MUI and Muhammadiyah. The significance of this work to the study of Indonesian Islam lies in its explanation of how conservatism enters those organizations.DOI: 10.15408/sdi.v21i2.1043
Islam, Local Culture, and Japan-Indonesian Relations

Published: November 2014

Local culture is undoubtedly a very important aspect to every nation. Having an awareness of local culture, especially among the youth, plays a great role in shaping a society and a state. For one to have an appreciation of another country’s culture, however, can be an important starting point in breaking down barriers of misperceptions or misunderstandings, and in helping to build global relationships. In support of this idea, the Japanese Embassy in Jakarta this year offered a special program called the Japan-East Asia Network of Exchange for Students and Youth (JENESYS) to strengthen the awareness of Japanese local culture among Muslim youth in Indonesia. In early 2014, the Japanese government, working in cooperation with PPIM (Center for the Study of Islam and Society) at UIN Syarif Hidayatullah in Jakarta, invited a number of university students to visit Japan.DOI: 10.15408/sdi.v21i2.1044
Embracing Life with AIDS: Psychotherapy through Guided Imagery and Music
Authors: Bruscia Kenneth E. 
Published: November 2014

This case describes individual psychotherapy with Matt, a 26-year old man recently infected with the AIDS virus. In the eleven sessions, Guided Imagery and Music (GIM) was used as the main technique within a psychodynamic orientation. Through an intense process of imagery transformation, Matt gained insight into how traumatic events from his past prevented him from coping with the emotional challenges of living with AIDS. Ultimately, this led him to confront one of the most important questions of his life: Shall I live dead, or shall I die living?

Published: November 2014

OBJECTIVE: To evaluate the impact of music therapy on breastfeeding rates among mothers of premature newborns. METHOD: In an open randomized controlled trial, mothers of premature neonates weighting ≤1750g were submitted to music therapy sessions three times a week for 60 minutes. The primary endpoint was breastfeeding rate (exclusive, predominant or continuous) at the moment of infant discharge and at the first follow-up visit (7-15 days after discharge). RESULTS: A total of 94 mothers (48 in the music therapy group and 46 in the comparison group) were studied. Breastfeeding was more frequent in the music therapy group at the moment of the infant hospital discharge (RR: 1.22; 95% CI: 0.99-1.51; P = .06; NNT = 6.3) and at the first follow-up visit (RR: 1.26; 95% CI: 1.01-1.57; P = .03; NNT = 5.6). Breastfeeding rates were higher in the intervention group at day 30 and day 60 after discharge, but these results were not statistically significant (RR: 1.21; 95% CI: 0.73-5.6 and RR: 1.28; 95% CI: 0.95-1.71 respectively). CONCLUSIONS: Music therapy increased breastfeeding rates in premature newborns at discharge, as well as 7-15 days later. This approach could be useful for increasing breastfeeding rates among premature newborns.[Editors note: The article presented here is republished from Jornal de Pediatria, 2011, 87(3), 206-212, doi: 10.2223/JPED.2086, with the kind permission from the publisher and the authors.]

Situation Songs - Therapeutic Intentions and Use in Music Therapy with Children
Authors: Kolar-Borsky Agnes , Holck Ulla 
Published: November 2014

The aim of this study was to survey the various therapeutic intentions behind the use of one particular improvisation method applied in pediatric music therapy, called the situation song (from the German term “Situationslied”- Plahl & Koch-Temming, 2008, p. 180). According to Plahl & Koch-Temming the term situation song describes an improvised song, which is sung by the therapist or/and the child and which relates to the actual occurrence and the therapeutic relationship. The presented study focuses on the therapist’s singing only.The study was conducted in stages: An elaboration of the first author’s clinical experience with situation songs (preunderstandings), a systematic analysis of relevant literature, followed by semi-structured interviews with three music therapists from Denmark, Austria and Germany. A flexible investigation approach was used, following hermeneutic principles.The findings of the study show that situation songs are regularly used by pediatric music therapists, especially during the work with children at an early developmental age. The various intentions behind the use of situation songs can be summarized as such: to create a therapeutic space; to support the therapeutic relationship; to enhance experience and development in the fields of emotion, behavior, expression and social skills; to express messages in language and to give structure to the child. The overall aim behind the use of situation songs is to offer essential experiences to the child in order to support his or her development.This study attempts to give an impulse to more international exchange of clinical terms applied in music therapy. The study was submitted as the first author’s master thesis in Music Therapy at the Aalborg University in Denmark. The second author supervised the process of the master thesis.

Published: November 2014

AbstractHere we review commonly used techniques for the production of large area and high quality graphene to meet the requirements of industrial applications, including epitaxial growth on SiC, chemical vapour deposition (CVD) on transition metals and growth from solid carbon source. The review makes a comparison of the growth mechanisms, quality (such as mobility and homogeneity) and properties of the resultant graphene, limitations and the prospect of each production method. A particular focus of the review is on direct (transfer free) growth on dielectric substrate as this is potentially one of the promising techniques for graphene production which can readily be integrated into existing semiconductor fabrication processes.
La « Shining India » étincelle-t-elle vraiment ?
Authors: Herrera Rémy 
Published: November 2014

Depuis quelques années, l’Inde est présentée dans la plupart des médias dominants comme un pays « émergent », classé dans la catégorie des « BRIC ». Maints observateurs de l’Inde vont jusqu’à la dépeindre comme une success story de ce début de XXIe siècle, en pointant les projecteurs sur les effets bénéfiques pour le supposé décollage économique des activités de quelques prodiges indiens de l’informatique ou du cinéma. Est-ce pourtant là le vrai visage de l’Inde d’aujourd’hui ? La terminologie de l’« émergence » fait quelquefois oublier l’épaisseur historique et la complexité sociale des pays candidats. Aussi proposerons-nous ici au lecteur une brève analyse introductive sur l’Inde, en nous intéressant successivement à son économie en général, puis au secteur agricole en particulier, et enfin aux inégalités – pour terminer par une brève analyse de la théorie d’Amartya Sen à ce sujet.
High Ratio Resuscitation in Patients with Systemic acquired Coagulopathy vs Endogenous Acute Coagulopathy
Authors: Derenbecker Robert 
Published: November 2014

ABSTRACT

Background
Two main mechanisms of coagulopathy related to trauma have been described: systemic acquired coagulopathy (SAC) and endogenous acute coagulopathy (EAC). Resuscitation with high ratios of fresh frozen plasma to packed red blood cells (FFP:PRBC) has been shown to improve patient outcomes. Systemic acquired coagulopathy is related to acidosis, hypothermia and hemodilution. Endogenous acute coagulopathy is related to severe hemorrhage and shock, with resultant effects on intrinsic clotting pathways inducing coagulopathy more rapidly than SAC. We hypothesize that high ratio resuscitation will show improved mortality outcomes for both SAC and EAC.

Study Design
A retrospective chart review was performed for patients at an urban level I trauma center. All patients with international normalized ratio (INR) > 1.2 during the first 6 hours after admission who received operative intervention and at least 6 units of PRBCs following traumatic injury were included. Patients with INR > 1.2 on admission were stratified to the EAC group while patients with normal admission INR with subsequent postoperative increase in INR > 1.2 were stratified into the SAC group. Transfusion ratios for FFP:PRBC were also collected for each patient. High ratio resuscitation was defined as FFP:PRBC ≥ 1:2 and low as FFP:PRBC < 1:2. Outcomes between groups were analyzed.

Results
Total of 95 patients met inclusion criteria. Fifty-six (59%) patients met criteria for EAC and 39 (41%) patients developed criteria for SAC during the first 6 hours of admission. The initial average base deficit was greater in EAC vs SAC patients (–6.3 vs –4.8, p = 0.03). Endogenous acute coagulopathy patients had a higher initial INR than SAC (1.4 vs 1.1, p = 0.001), and a higher average injury severity score (ISS) (27.6 vs 21.5, p = 0.03). Regarding transfusion ratios, for both EAC and SAC, a high transfusion ratio when compared to a low transfusion ratio conveyed improved mortality (EAC: 32.5 vs 81%, p = 0.01; SAC:9 vs 64.7%, p = 0.03). For high ratio resuscitation in both groups, patients with SAC showed improved mortality compared to EAC (9 vs 32.5%, p = 0.01).

Conclusion
For patients with EAC and SAC, a high transfusion ratio conveyed an overall improvement in mortality. However, subgroup analysis demonstrated that despite a high transfusion ratio, EAC patients continued to have a significantly higher mortality than SAC patients. Further investigations into the mechanisms involved in EAC and interventions to improve outcomes are needed.

Investigation of the Dynamic Behavior of Bisumanenyl
Authors: Shrestha Binod Babu , Karanjit Sangita , Higashibayashi Shuhei , Amaya Toru , Hirao Toshikazu , Sakurai Hidehiro 
Published: November 2014

AbstractThe behavior of bisumanenyl is dynamic as a result of inversion of each of its sumanene bowls and rotation between the two bowls. This behavior was fully elucidated by a combination of NMR experiments and density functional theory calculations. The MM (or PP) and MP diastereomers are in thermodynamic equilibrium at room temperature and the MM (PP) diastereomer is 1.4–1.9 kcal mol−1 more stable than MP diastereomer. The calculated energy for inversion between the two forms of the bowl is 19.2 kcal mol−1. The MM (PP) and MP diastereomers have two rotational stable conformers that rapidly interconvert as a result of the low rotational energy barriers, which were calculated to be 3.9 and 8.9 kcal mol−1, respectively.
Iridium‐Catalyzed Synthesis of Diaryl Ethers by Means of Chemoselective CF Bond Activation and the Formation of BF Bonds
Authors: Chen Jianping , Zhao Keyan , Ge Bingyang , Xu Chongying , Wang Dawei , Ding Yuqiang 
Published: November 2014

AbstractTransition‐metal‐catalyzed CF activation, in comparison with CH activation, is more difficult to achieve and therefore less fully understood, mainly because carbon–fluorine bonds are the strongest known single bonds to carbon and have been very difficult to cleave. Transition‐metal complexes are often more effective at cleaving stronger bonds, such as C(sp2)X versus C(sp3)X. Here, the iridium‐catalyzed CF activation of fluorarenes was achieved through the use of bis(pinacolato)diboron with the formation of the BF bond and self‐coupling. This strategy provides a convenient method with which to convert fluoride aromatic compounds into symmetrical diaryl ether compounds. Moreover, the chemoselective products of the CF bond cleavage were obtained at high yields with the CBr and CCl bonds remaining.
Measuring calcium, potassium, and nitrate in plant nutrient solutions using ion‐selective electrodes in hydroponic greenhouse of some vegetables

Published: November 2014

AbstractGenerally, the life cycle of plants depends on the uptake of essential nutrients in a balanced manner and on toxic elements being under a certain concentration. Lack of control of nutrient levels in nutrient solution can result in reduced plant growth and undesired conditions such as blossom‐end rot. In this study, sensitivity and selectivity tests for various polyvinylchloride (PVC)‐based ion‐selective membranes were conducted to identify those suitable for measuring typical concentration ranges of macronutrients, that is, NO3−, K+, and Ca2+, in hydroponic solutions. The sensitivity and selectivity of PVC‐membrane‐based ion‐selective sensors prepared with tetradodecylammoniumnitrate for NO3−, valinomycin for K+, and Ca ionophore IV for Ca2+ were found to be satisfactory for measuring NO3−, K+, and Ca2+ ions in nutrient solutions over typical ranges of hydroponic concentrations. Potassium, calcium, and nitrate levels that were utilized by cucumber and tomato seedlings in the greenhouse were different. The findings show that tomato plants consumed less amounts of nitrate than cucumber plants over the first 2 months of their growth. We also found that the potassium intake was higher than other nutritional elements tested for all plants.
Portal vein patency after pancreatoduodenectomy for periampullary cancer

Published: November 2014

Abstract

Background
The fate of the portal vein (PV) after pancreatoduodenectomy, especially its long-term patency and associated complications, has received little attention. The aim of this study was to explore the long-term patency rate of the PV after pancreatoduodenectomy, focusing on risk factors for PV stenosis/occlusion and associated complications.

Methods
Serial CT images of patients who underwent pancreatoduodenectomy for periampullary cancer between January 2000 and June 2012 in a single institution were evaluated for PV stenosis or occlusion.

Results
A total of 826 patients were enrolled. The PV stenosis/occlusion rate after pancreatoduodenectomy was 19·6 per cent and the 5-year patency rate 69·9 per cent. The most frequent cause of PV stenosis/occlusion was local recurrence followed by postoperative change and PV thrombosis. Patients who underwent PV resection had a higher PV stenosis/occlusion rate than those who did not (51 versus 17·4 per cent; P &lt; 0·001). The 3-year patency rate was highest in patients with cancer of the ampulla of Vater and lowest in patients with pancreatic cancer (91·9 versus 55·5 per cent respectively; P &lt; 0·001). Multivariable analysis showed that risk factors for PV stenosis/occlusion included primary tumour location, chemoradiotherapy and PV resection. PV stenosis or occlusion without disease recurrence was observed in 17·3 per cent of the patients. PV resection and grade B or C pancreatic fistula were independent risk factors for PV stenosis/occlusion. Among 162 patients with PV stenosis or occlusion, five (3·1 per cent) had fatal recurrent gastrointestinal bleeding.

Conclusion
PV stenosis or occlusion is common after pancreatoduodenectomy, particularly if the PV has been resected and/or chemoradiotherapy was given after surgery. Although recurrence is the most frequent cause of PV stenosis/occlusion, this complication is found in a significant proportion of patients without disease recurrence.
