PurposeThe present study investigated whether L-arginine supplementation reduces blood pressure (BP) in hypertensive subjects with different ACE genotypes.MethodsEight male hypertensive patients received L-arginine (2 or 4 g/day) or a placebo for a period of 4 days prior an exercise test. Statistical analysis consisted of one-way analysis of variance.ResultsL-arginine supplementation induced a statistically significant (<i>p</i> > 0.05) reduction in systolic BP measured during rest (reductions of 7.8% and 12.3% with 2 and 4 g/day, respectively), exercise (reductions of 11.8% and 10.4% with 2 and 4 g/day, respectively), and recovery (reductions of 11.7% and 10.7% with 2 and 4 g/day, respectively). The observed magnitude of BP reduction suggests an association with ACE polymorphism; a larger effect was seen with the II and DI genotypes compared with the DD genotype (II: 121 mmHg and DI: 133 mmHg vs. DD: 144 mmHg).ConclusionsThe results showed that L-arginine supplementation at low doses was efficient in reducing BP and that vasodilator actions that occurred through the secretion of nitric oxide might be ACE genotype dependent.
Geometric Interpretation of a Non-Linear Beam Finite Element on The Lie Group SE(3)
Authors: Sonneville Valentin , Cardona Alberto , Brüls Olivier 
Published: August 2014

Abstract
Recently, the authors proposed a geometrically exact beam finite element formulation on the Lie group SE(3). Some important numerical and theoretical aspects leading to a computationally efficient strategy were obtained. For instance, the formulation leads to invariant equilibrium equations under rigid body motions and a locking free element. In this paper we discuss some important aspects of this formulation. The invariance property of the equilibrium equations under rigid body motions is discussed and brought out in simple analytical examples. The discretization method based on the exponential map is recalled and a geometric interpretation is given. Special attention is also dedicated to the consistent interpolation of the velocities.
The relationship between the alkaline phosphatase network and the haematopoiesis in mice subjected to whole-body irradiation
Authors: Almohamad Khaled M. , Alsheikh Fatima M. 
Published: August 2014

Abstract
Purpose: To investigate the relationship between the alkaline phosphatase (ALP) network of the marrow stroma and the haematopoietic regeneration after mice whole-body irradiation. Materials and methods: Three groups of mice were irradiated with a non-lethal ionising radiation dose: the fi rst one received an intraperitoneal injection of Levamisole, ALP inhibitor, 24 h before irradiation; the second one received an intraperitoneal injection of Lisinopril, haematopoiesis inhibitor, 24 h before irradiation; the third was left untreated, but irradiated. The fourth group, untreated and not irradiated, was the control. The total surface occupied by ALP positive processes, revealed by means of ALP cytochemistry in the marrow area, was evaluated semi-quantitively. Nucleated bone marrow cells were also counted. Results: ALP network began to increase 24 h after irradiation to reach a maximum after 72 h, when the bone marrow was almost become completely empty of the haematopoietic cells. This increase advances the haematopoietic recovery. This process was substantially delayed when the mice were injected with Levamisole 24 h before irradiation. On the contrary, ALP network increased strongly since the fi rst day after irradiation when the mice were injected with Lisinopril 24 h before irradiation. Conclusions: These data have indicated that the haematopoietic recovery and repopulation of the bone marrow were advanced by the ALP network recovery.
Comparing methods of measuring sea-ice density in the East Antarctic

Published: August 2014

AbstractRemotely sensed derivation of sea-ice thickness requires sea·ice density. Sea-ice density was estimated with three techniques during the second Sea Ice Physics and Ecosystem eXperimett (SIPEX-II, September-November 2012, East Antarctica). The sea ice was first-year highly deformed, mean thicknsss 1.2 m with layers, consistent with rafting, and 6-7/10 columnar ice and 3/10 granular ice. Ice density was found to be lower than values (900-920 kg m−3 used previously to derive ice thickness,, with columnar ice mean density of 870 kg m− 3. At two different ice stations the mean density of the ice was 800 kg m–3, the lower density reflecting a high percentage of porous granular ice at the second station. Error estimates for mass/volume and liquid/solid water methods are presented. With 0.1 m long, 0.1 m core samples, the error on individual density estimates is 28 kg m-3. Errors are larger for smaller machined blocks. Errors increase to 46 kg m-3 if the liquid/solid volume method is used. The mass/vouume method has a low bias due to brine drainage of at least 5%. Bulk densities estimated from ice and snow measurements along 100 m transects were high, and likely unrealistic as the assumption of isostatcc balance is not suitable over these length scales in deformed ice.
À l’origine de Caunes-Minervois : Buffens
Authors: Baudreu Dominique , Rancoule Guy 
Published: August 2014

Discovered by speleologists in a cave of the Argent-Double pass, in the north of the village of Caunes and at a small distance from the place called “ Roc de Buffens”, a series of Late Antiquity ceramics raises the problem of the occupation of natural cavities traditionally and wrongly interpreted as places of refuge in the context of the “ Great Invasions”.
The likely contemporaneousness between the ceramics and the period of formation of the place-name ” Buffens”, doubtless of Gothic origin, allows a modest historiographical evaluation on the ancient villa Buffinis. This name preceded that of the “ villa” of Caunes, the anteriority of the first name being clearly evoked in a text of the end of the VIIIth century which also mentions the Saint-Geniès church, the ancient parochial church of Caunes. Such a place of worship may be the heir to a former religious centre which would have existed before the villa during the early Christian period. As for the deserted habitat, evoked by erudite tradition in the vicinity of the Saint-Geniès church, or further North, habitat that would have preceded the creation of the village of Caunes, its very existence deserves to be discussed for the present.
Influences of the European Avant–Garde on the Relationship between Literature and Music in the Works of Jakob Jež
Authors: Vrhunc Larisa 
Published: August 2014

One of Jakob Jež's favourite instruments is the vocal; he has therefore dedicated much of his time to the selection of textual material and its incorporation into his music. Composers' attitude towards literature has been changing throughout history, with the post-war avant-garde period offering many innovative solutions, which is also reflected in the vocal and instrumental music by Jakob Jež.

El objetivo de este trabajo fue conocer la distribución del venado temazate rojo (Mazama temama) en Puebla, a través de un muestreo en campo, fundamentado en referencias bibliográficas y entrevistas a personas relacionadas con la especie. El muestreo se realizó mediante el recorrido de cuadrantes lineales con longitud variable y anchura fija, para determinar la presencia del venado por medio de la observación directa (animales observados) e indirecta (huellas, excretas, talladeros o animales cautivos). La distribución regional se obtuvo a partir de la información generada en los sitios donde se corroboró la presencia de temazate, con ayuda de un Sistema de Información Geográfica (SIG), empleando el programa Arc View 3.2. Los resultados del SIG sugieren que el venado se distribuye en el Totonacapan y la zona poniente de la Sierra Norte y en la zona oriental de la Sierra Negra, en una superficie total de 99,410.96 ha. El índice de similitud (95.2) entre sierras, por evidencia directa o por rastros, indica presencia y distribución similar de temazate rojo, concordando con los resultados del SIG. Se concluye que la distribución regional de temazate rojo en Puebla se concentra en 42 municipios pertenecientes a la Sierra Norte y zona oriental de la Sierra Negra.

Published: August 2014

Os terreiros afro-brasileiros são considerados como espaços sociais, míticos, simbólicos, onde a natureza e seus fiéis se unem para viver uma realidade diferente daquela que o cotidiano ou a sociedade lhes apresenta como o real, na qual as pessoas que o constituem acreditam. São vistos como lócus da força vital que pode ser conservada, manuseada e transmitida. Suas instalações estão impregnadas do simbolismo religioso e são tidas como extensões da essência vital de suas ‘entidades’ patronas vinculada ao modo de vida urbano, na construção de suas organizações e discursos subalternos e no confronto histórico de suas crenças.
High-Resolution Imagery and the Recovery of Surface Architectural Patterns
Authors: Stone Elizabeth C. 
Published: August 2014

AbstractIn large arid floodplains, like that of southern Iraq, the rise of the water table associated with irrigation can result in surface salt concentrations over the remains of subsurface architecture. These traces are visible only from the air but are sometimes captured by commercially available submeter pixel imagery. This article describes the methods used and some of the results of a project using QuickBird, WorldView-1, and WorldView-2 imagery to investigate settlement systems in southern Mesopotamia dating between the fourth and first millennia B.C. Following a discussion of methods used to better predict which images of which sites will produce the desired results, a brief exploration of key anthropological questions that these data allow us now to ask will be presented.

Curriculum mapping within an Australian master of chiropractic program: Congruence between published evidence for chiropractic and student assessment tasks
Authors: Gorrell Lindsay , Beirman Robyn L. , Vemulpad Subramanyam R. 
Published: August 2014

Objective
This study sought to determine congruence between student assessment tasks within the master of chiropractic curriculum at Macquarie University and 2 separate but related domains: (1) disorders commonly presenting to chiropractors and (2) musculoskeletal conditions for which there is published evidence that chiropractic treatment is effective.

Methods
A literature review was undertaken to determine which musculoskeletal disorders commonly present to chiropractors and the conditions for which there is published evidence that chiropractic treatment is effective. These 2 domains were then mapped to the assessment tasks within the curriculum and analyzed. The proportion of time allocated to theory versus skill acquisition was also determined.

Results
Assessment tasks within the curriculum specifically focus on low back pain, neck pain, lower extremity pain, thoracic pain, and adhesive capsulitis. This curriculum mapping demonstrates congruence between the student assessment tasks and published evidence for chiropractic. The assessments also contain an appropriate balance between theory and skills acquisition.

Conclusion
There is congruence between the assessment tasks within the curriculum and the 2 domains against which it was mapped. Thus, completion of the curriculum provides training relevant to conditions that commonly present to chiropractors and musculoskeletal conditions for which chiropractic treatment is effective.

Published: August 2014

AbstractThe crustal remnant field on Mars rotates with the planet at a period of 24 h 37 min, constantly varying the magnetic field configuration interacting with the solar wind. Until now, there has been no self‐consistent modeling investigation on how this varying magnetic field affects the solar wind plasma interaction. Here we include the rotation of this localized crustal field in a multispecies single‐fluid MHD model of Mars and simulate an entire day of solar wind interaction under normal solar wind conditions. The MHD model results are compared with Mars Global Surveyor (MGS) magnetic field observations and show very close agreement, especially for the field strength along almost all of the 12 orbits on the day simulated. Model results also show that the ion escape rates slowly vary with rotation, generally anticorrelating with the strength of subsolar magnetic crustal sources, with some time delay. In addition, it is found that in the intense crustal field regions, the densities of heavy ion components enhance significantly along the MGS orbit, implying strong influence of the crustal field on the ionospheric structures.
Advanced time series synthesizer for simulation of joint rain attenuation conditions
Authors: Nebuloni R. , Capsoni C. , Luccini M. 
Published: August 2014

AbstractThis contribution presents a model to generate time series of rain attenuation by adapting a large set of rain attenuation measurements to different locations. The proposed model allows generating rainy and not rainy conditions for multiple stations in a large geographical area, reproducing the actual spatial and temporal variability of the rain process, with limited computational effort. Single site and joint statistics of rain attenuation obtained by the time series of measurements are discussed. The model is used to show the effectiveness, in terms of link margin, of gateway networks in smart diversity arrangement, for different separation distances among sites.

ObjectiveTo evaluate the association between long working hours and risk of coronary heart disease (CHD) estimated by Framingham risk score (FRS) in Korean adults.MethodsThis study evaluated adult participants in Korean National Health and Nutrition Examination Survey IV (2007–2009). After inclusion and exclusion criteria were applied, the final sample size for this study model was 8,350. Subjects were asked about working hours and health status. Participants also completed physical examinations and biochemical measurement necessary for estimation of FRS. Multiple logistic regression was conducted to investigate the association between working hours and 10‐year risk for CHD estimated by FRS.ResultsCompared to those who work 31–40 hr, significantly higher 10‐year risk was estimated among subjects working longer hours. As working hours increased, odds ratio (OR) for upper 10 percent of estimated 10‐year risk for CHD was increased up to 1.94.ConclusionsLong working hours are significantly related to risk of coronary heart disease.

Optogenetic Engineering: Light‐Directed Cell Motility
Authors: Hughes Robert M. , Lawrence David S. 
Published: August 2014

AbstractGenetically encoded, light‐activatable proteins provide the means to probe biochemical pathways at specific subcellular locations with exquisite temporal control. However, engineering these systems in order to provide a dramatic jump in localized activity, while retaining a low dark‐state background remains a significant challenge. When placed within the framework of a genetically encodable, light‐activatable heterodimerizer system, the actin‐remodelling protein cofilin induces dramatic changes in the F‐actin network and consequent cell motility upon illumination. We demonstrate that the use of a partially impaired mutant of cofilin is critical for maintaining low background activity in the dark. We also show that light‐directed recruitment of the reduced activity cofilin mutants to the cytoskeleton is sufficient to induce F‐actin remodeling, formation of filopodia, and directed cell motility.
Exceptional Isotopic‐Substitution Effect: Breakdown of Collective Proton Tunneling in Hexagonal Ice due to Partial Deuteration
Authors: Drechsel‐Grau Christof , Marx Dominik 
Published: August 2014

AbstractMultiple proton transfer controls many chemical reactions in hydrogen‐bonded networks. However, in contrast to well‐understood single proton transfer, the mechanisms of correlated proton transfer and of correlated proton tunneling in particular have remained largely elusive. Herein, fully quantized ab initio simulations are used to investigate H/D isotopic‐substitution effects on the mechanism of the collective tunneling of six protons within proton‐ordered cyclic water hexamers that are contained in proton‐disordered ice, a prototypical hydrogen‐bonded network. At the transition state, isotopic substitution leads to a Zundel‐like complex, [HO⋅⋅⋅D⋅⋅⋅OH], which localizes ionic defects and thus inhibits perfectly correlated proton tunneling. These insights into fundamental aspects of collective proton tunneling not only rationalize recent neutron‐scattering experiments, but also stimulate investigations into multiple proton transfer in hydrogen‐bonded networks much beyond ice.

Published: August 2014

AbstractDie Reaktivität von Phenyldiazenen wurde zum Ende der 1960er Jahre intensiv untersucht, doch ist bisher kaum etwas über ihr Verhalten unter sauren Bedingungen bekannt. Ausgehend von der Bildung von Phenyldiazenen aus Phenylazocarboxylaten beschreiben wir nun, wie Phenyldiazene gezielt in ionischen oder radikalischen Reaktionen umgesetzt werden können. Cycloadditionsreaktionen mit Furanen, die zu Pyridaziniumsalzen führen, sind die ersten Beispiele für den direkten Abfang von Phenyldiazenen unter Erhaltung der NN‐Einheit.

Published: August 2014

AbstractThe structural preciseness of dendrimers makes them perfect drug delivery carriers, particularly in the form of dendrimer–drug conjugates. Current dendrimer–drug conjugates are synthesized by anchoring drug and functional moieties onto the dendrimer peripheral surface. However, functional groups exhibiting the same reactivity make it impossible to precisely control the number and the position of the functional groups and drug molecules anchored to the dendrimer surface. This structural heterogeneity causes variable pharmacokinetics, preventing such conjugates to be translational. Furthermore, the highly hydrophobic drug molecules anchored on the dendrimer periphery can interact with blood components and alter the pharmacokinetic behavior. To address these problems, we herein report molecularly precise dendrimer–drug conjugates with drug moieties buried inside the dendrimers. Surprisingly, the drug release rates of these conjugates were tailorable by the dendrimer generation, surface chemistry, and acidity.

Published: August 2014

AbstractThe orientation of metal–organic supercontainer (MOSC) molecules in Langmuir films was systematically studied at the air–water interface. The acidity of the aqueous subphases plays a significant role in tuning the orientation of MOSC molecules in the Langmuir films. Furthermore, Langmuir–Blodgett films of MOSCs were prepared and the uniform multilayer structures demonstrated various surface properties, depending on their conditions of fabrication. Our use of Langmuir films provides a novel approach to access tunable assemblies of MOSC molecules in two‐dimensional thin films.

AbstractDirect β‐to‐β linked branched and cyclic porphyrin trimers and pentamers have been synthesized by the Suzuki–Miyaura coupling of β‐borylporphyrins and β‐bromoporphyrins. The cyclic porphyrin trimer, the smallest directly linked cyclic porphyrin wheel to date, and its twined pentamer, exhibit small electrochemical HOMO–LUMO gaps, broad nonsplit Soret bands, and red‐shifted Q‐bands, thus indicating large electronic interactions between the constituent porphyrin units.
