L-Carnipure® in Human Nutrition
Authors: Held Ulla S.
Published: March 2007

L-Carnitine (?-hydroxy-?-trimethylaminobutyric acid) plays a crucial role in fat and carbohydrate metabolism and is required for the proper functioning of heart and muscle. In 1905, L-carnitine was isolated for the first time from muscle tissue and its structure was established
in 1927. L-Carnitine was shown to be an essential nutrient for a meal worm (Tenebrio molitor) and was therefore called vitamin BT.In the search for the perfect physique, consumers are discovering the health benefits of L-carnitine. Studies show that L-carnitine supplements
not only help with weight management programs, but also optimize performance during exercise, delay the onset of fatigue and improve the recovery process. Extensive clinical data indicate that supplemental L-carnitine can positively support cardiovascular health, while other studies show beneficial
effects for pregnant women, elderly people or people who follow a vegetarian or meat-reduced diet and thus miss out on natural L-carnitine in the diet. L-Carnipure® is a special grade of L-carnitine, manufactured by the swiss life sciences company lonza. Thanks to a unique natural
fermentation process with an integrated biotransformation step, lonza is the only L-carnitine manufacturer capable of supplying pure L-carnitine without any unnatural D-isomer, hence the brand name and sign of quality assurance, L-carnipure®.
Race and ethnicity in genetic research
Authors: Sankar Pamela , Cho Mildred K. , Mountain Joanna
Published: March 2007

Use of race and ethnicity terms in genetic research continues to generate controversy. Despite differing opinions about their basis or relevance, there is some agreement that investigators using these terms should: explain why the terms or categories were used, define them carefully, and apply them consistently. An important question is whether these recommendations are reflected in practice. Here we addressed this question based on 330 randomly selected articles published between 2001 and 2004 that reported on genetic research and used one or more words from a defined list of race, ethnicity, or population terms. The recommendation that authors using race or ethnicity terms explain the basis for assigning them to study populations was met infrequently (9.1%), and articles that used race and ethnicity as variables were no more likely than those that used them only to label a sample to provide these details. No article defined or discussed the concepts of race or ethnicity. With limited exceptions, current practice does not reflect repeated recommendations for using race or ethnicity terms in genetic research. This study provides a baseline against which to measure future trends. © 2007 Wiley‐Liss, Inc.

Craniosynostosis, the premature fusion of one or more cranial sutures, affects 1 in 2,500 live births. Isolated single‐suture fusion is most prevalent, with sagittal synostosis occurring in 1/5,000 live births. The etiology of isolated (nonsyndromic) single‐suture craniosynostosis is largely unknown. In syndromic craniosynostosis, there is a highly nonrandom pattern of causative autosomal dominant mutations involving TWIST1 and fibroblast growth factor receptors (FGFRs). Prior to our study, there were no published TWIST1 mutations in the anti‐osteogenic C‐terminus, recently coined the TWIST Box, which binds and inhibits RUNX2 transactivation. RUNX2 is the principal master switch for osteogenesis. We performed mutational analysis on 164 infants with isolated, single‐suture craniosynostosis for mutations in TWIST1, the IgIIIa exon of FGFR1, the IgIIIa and IgIIIc exons of FGFR2, and the Pro250Arg site of FGFR3. We identified two patients with novel TWIST Box mutations: one with isolated sagittal synostosis and one with isolated coronal synostosis. Kress et al. [2006] reported a TWIST Box “nondisease‐causing polymorphism” in a patient with isolated sagittal synostosis. However, compelling evidence suggests that their and our sequence alterations are pathogenic: (1) a mouse with a mutation of the same residue as our sagittal synostosis patient developed sagittal synostosis, (2) mutation of the same residue precluded TWIST1 interaction with RUNX2, (3) each mutation involved nonconservative amino acid substitutions in highly conserved residues across species, and (4) control chromosomes lacked TWIST Box sequence alterations. We suggest that genetic testing of patients with isolated sagittal or coronal synostosis should include TWIST1 mutational analysis. © 2007 Wiley‐Liss, Inc.

On the observation of traveling acoustic waves in the solar atmosphere using a magneto‐optical filter
Authors: Haberreiter M. , Finsterle W. , Jefferies S. M.
Published: March 2007

In contrast to low‐frequency waves that are trapped in the cavity of the Sun, high‐frequency waves can travel freely in the solar atmosphere. By modelling the observed intensity signal in the red and blue wings of K I 7699 Å and Na I 5890 Å, we aim to better understand the measurements carried out with the Magneto‐Optical Filter at Two Heights (MOTH) experiment. We model the observed intensity signal with radiative transfer calculations carried out with the COde for Solar Irradiance (COSI). Furthermore, we derive the formation height of the lines in order to analyze to what extent the contribution functions are modulated by the acoustic waves. We find a phase lag between the red and blue filter for acoustic waves with a frequency above ≈7 mHz and conclude that a frequency dependent data analysis is required for higher frequencies.

Triple correlations in local helioseismology
Authors: Pijpers F. P.
Published: March 2007

A central step in time‐distance local helioseismology techniques is to obtain travel times of packets of wave signals between points or sets of points on the visible surface. Standard ways of determining group or phase travel times involve cross‐correlating the signal between locations at the solar photosphere and determining the shift of the envelope of this cross correlation function, or a zero crossing, using a standard wavelet or a reference wave packet. Here a novel method is described which makes use of triple correlations, i.e. cross‐correlating signal between three locations. By using an average triple correlation as reference, differential travel times can be extracted in a straightforward manner. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Linear sensitivity of helioseismic travel times to local flows
Authors: Birch A. C. , Gizon L.
Published: March 2007

Time‐distance helioseismology is a technique for measuring the time for waves to travel from one point on the solar surface to another. These wave travel times are affected by advection by subsurface flows. Inferences of plasma flows based on observed travel times depend critically on the ability to accurately model the effects of subsurface flows on time‐distance measurements. We present a Born‐approximation based computation of the sensitivity of time‐distance travel times to weak, steady, inhomogeneous subsurface flows. Three sensitivity functions are obtained, one for each component of the 3D vector flow. We show that the depth sensitivity of travel times to horizontally uniform flows is given approximately by the kinetic energy density of the oscillation modes which contribute to the travel times. For flows with strong depth dependence, the Born approximation can give substantially different results than the ray approximation. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Meridional circulation and differential rotation in the solar convection zone

With the development of local helioseismology, such as the time‐distance technique, investigation of meridional flow and differential rotation in the solar convection zone has become possible. I summarize recent observational results, and review theoretical considerations of meridional circulation in relation to differential rotation, which is now well unveiled in the solar convection zone by helioseismology.

Surface magnetic field effects in local helioseismology
Authors: Schunker H. , Braun D. C. , Cally P. S.
Published: March 2007

Using helioseismic holography strong evidence is presented that the phase (or equivalent travel‐time) of helioseismic signatures in Dopplergrams within sunspots depend upon the line‐of‐sight angle in the plane containing the magnetic field and vertical directions. This is shown for the velocity signal in the penumbrae of two sunspots at 3, 4 and 5 mHz. Phasesensitive holography demonstrates that they are significantly affected in a strong, moderately inclined magnetic field. This research indicates that the effects of the surface magnetic field are potentially very significant for local helioseismic analysis of active regions. (© 2007 WILEY‐VCH Verlag GmbH & Co.

Magnetoseismic signatures and flow diagnostics beneath magnetic regions
Authors: Lindsey C. , Schunker H. , Cally P. S.
Published: March 2007

One of the major, important developments in local helioseismology was the discovery by Duvall et al. (1996) that the travel times of seismic waves into sunspots from the surrounding quiet Sun significantly exceed the same in the reverse direction, a behavior they suggested was the result of rapid downflows directly beneath the sunspot photosphere. This led to the need for rapid near‐surface horizontal inflows to replace the mass evacuated from the sunspot subphotosphere by such downflows. The lack of independent evidence for such inflows led to the suggestion that the travel‐time asymmetry could be explained by a relative phase delay in the response of the sunspot photosphere to incoming waves with respect to that of the quiet Sun. In the succeeding ten years major progress has been made in our understanding of how magnetic photospheres respond to incoming waves, at the instigation of theoretical work by Spruit, Cally and Bogdan. This has led to the recognition of inclined penumbral magnetic fields as a major avenue for control work on the subject of the traveltime asymmetry and its relation to the absorption of p‐modes by magnetic regions. A major recent development has been the discovery by Schunker et al. (2005) that the phase of this response in Doppler observations of penumbral photospheres depends strongly on the vantage of the Doppler measurements projected into the vertical plane of the magnetic field. This discovery heavily reinforces the proposition that the travel‐time asymmetry is largely the signature of the same irreversible damping processes that are responsible for the strong absorption of p‐modes in magnetic regions. We will elaborate on the implications of the foregoing developments respecting the diagnostics of subphotospheric flows based on seismic observations in which magnetic regions cannot be avoided.

Leakage of photospheric motions into the magnetic solar atmosphere: new prospects of magneto‐seismology
Authors: Erdélyi R. , Pintér B. , Malins C.
Published: March 2007

The leakage and coupling of solar global oscillations to the overlaying magnetized solar atmosphere is investigated in this paper. Solar global acoustic oscillations may couple through resonant absorption to atmospheric local magnetic eigenoscillations (i) resulting in small shifts of the order of μHz in the real part of their frequencies as compared to their non‐magnetic counterparts, and (ii) causing dissipation of wave energy and a consequent line broadening of the modes. Alternatively, global modes may also penetrate deeply into the magnetized solar atmosphere through leakage along magnetic field lines causing small‐scale structuring in the transition region and low corona. By analyzing the dynamic fragmentation generated by direct wave propagations, one may deduce diagnostic information about the geometric and physical properties of the local magnetic environment in the atmosphere. A few numerical examples are presented here to demonstrate the leakage of global oscillations and its influence and omnipotence on the dynamics of the lower solar atmosphere.

Scattering of p‐modes by a thin fluxtube in a stratified atmosphere
Authors: Gordovskyy M. , Jain R.
Published: March 2007

In the present paper we investigate scattering of low and intermediate degree p‐modes on a thin magnetic fluxtube embedded into a stratified polytropic atmosphere. Using the Born approximation approach we find the solution of linearized MHD equations and calculate resulting phase shifts of scattered waves for different sets of fluxtube parameters. Possible application of the results to the analysis of observational data is discussed. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
SLiM: a code for the simulation of wave propagation through an inhomogeneous, magnetised solar atmosphere
Authors: Cameron R. , Gizon L. , Daiffallah K.
Published: March 2007

In this paper we describe the semi‐spectral linear MHD (SLiM) code which we have written to follow the interaction of linear waves through an inhomogeneous three‐dimensional solar atmosphere. The background model allows almost arbitrary perturbations of density, temperature, sound speed as well as magnetic and velocity fields. We give details of several of the tests we have used to check the code. The code will be useful in understanding the helioseismic signatures of various solar features, including sunspots.

The solar acoustic simulator: applications and results
Authors: Hanasoge S. M. , Duvall T. L.
Published: March 2007

It is important to understand the limits and accuracy of helioseismic techniques in their ability to probe the solar interior. The availability of a method that is able to compute the solar acoustic wave field in the presence of thermal or flow perturbations affords us a means to place bounds on detectability and accuracy of inferences of interior perturbations. We describe the technique used to simulate wave propagation within a spherical shell that extends from a desired depth (not including the center) into the solar atmosphere and which possesses a solar like stratification.

First local helioseismic experiments with CO5BOLD
Authors: Steiner O. , Vigeesh G. , Krieger L. , Wedemeyer‐Böhm S. , Schaffenberger W. , Freytag B.
Published: March 2007

With numerical experiments we explore the feasibility of using high frequency waves for probing the magnetic fields in the photosphere and the chromosphere of the Sun.We track a plane‐parallel, monochromatic wave that propagates through a non‐stationary, realistic atmosphere, from the convection‐zone through the photosphere into the magnetically dominated chromosphere, where it gets refracted and reflected. We compare the wave travel time between two fixed geometrical height levels in the atmosphere (representing the formation height of two spectral lines) with the topography of the surface of equal magnetic and thermal energy density (the magnetic canopy or β = 1 contour) and find good correspondence between the two. We conclude that high frequency waves indeed bear information on the topography of the ‘magnetic canopy’. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Towards using modern data assimilation and weather forecasting methods in solar physics
Authors: Brun A. S.
Published: March 2007

We discuss how data assimilation and forecasting methods developed in Earth's weather prediction models could be used to improve our capability to anticipate solar dynamical phenomena and assimilate the huge amount of data that new solar satellites, such as SDO or Hinode, will provide in the coming years. We illustrate with some simple examples such as the solar magnetic activity cycle, the eruption of CMEs, the real potential of such methods for solar physics. We believe that we now need to jointly develop solar forecasting models, whose purpose are to assimilate observational data in order to improve our predictability power, with “first principle” solar models, whose purpose is to understand the underpinning physical processes behind the solar dynamics. These two complementary approaches should lead to the development of a solar equivalent of Earth's general circulation model. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Helioseismology program for Solar Dynamics Observatory
Authors: Kosovichev A. G. , HMI Science Team
Published: March 2007

An overview of the science investigation program for the Helioseismic and Magnetic Imager (HMI) of the Solar Dynamics Observatory (SDO) space mission scheduled for launch in 2008 is presented. The HMI investigation encompasses three primary objectives of the Living With a Star Program:.rst, to determine how and why the Sun varies; second, to improve our understanding of how the Sun drives global change and space weather; and third, to determine to what extent predictions of space weather and global change can be made and to prototype predictive techniques. Helioseismology provides unique tools to study the basic mechanisms of the Sun's magnetic activity and variability. It plays a crucial role in all HMI investigations, which include convection‐zone dynamics and the solar dynamo; origin and evolution of sunspots, active regions and complexes of activity; sources and drivers of solar activity and disturbances; links between the internal processes and dynamics of the corona and heliosphere; and precursors of solar disturbances for space‐weather forecasts. We describe new unique opportunities for helioseismology studies with HMI data, in combination with data from the other SDO instruments, Atmospheric Imaging Assembly (AIA) and Extreme‐ultraviolet Variability Experiment (EVE), and also from various space and ground‐based observatories. The complete HMI science investigation and data analysis plan is available at http://hmi.stanford.edu. (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Precise bacterial polyprenol length control fails in Saccharomyces cerevisiae
Authors: Poznański Jarosław , Szkopinska Anna
Published: March 2007

A comparison of amino acid sequences of yeast Rer2p and Srt1p Z‐prenyltransferases shows that the spatial organization of their substrate tunnels agrees with that determined by X‐ray for the E. coli undecaprenyl diphosphate synthase (UPPs). The observed trend in the maxima of product length distribution shifted from C55 in UPPs to C80 in Rer2p and to C110 in Srt1p. This suggests a significant increase in the size of the enzyme hydrophobic tunnel from ∼1000 Å3 of E. coli UPPs to ∼1300 Å3 required to accommodate C80 in Rer2p and to 1700 Å3 for C110 in Srt1p. Moreover, Srt1p products reaching C290 indicate the failure of a strict bacterial‐like chain length control. On the basis of E. coli UPPs crystallographic structure the yeast Rer2p model was constructed. In the model three amino acid residues inserted into the sequence corresponding to the “floor” region of the tunnel extends the bottom loop what results in the required increase of the tunnel volume. Moreover, thermal fluctuations of this loop occasionally create a hole in the tunnel floor, making escape of polyprenol ω end out of the tunnel possible what switches off the control mechanism of product length thereby allowing a practically unlimited elongation process leading to an exponential distribution of longer chain polyprenols. © 2007 Wiley Periodicals, Inc.

When oil and wind turbine companies make green sense together
Authors: Backer Lise
Published: March 2007

In this article I contribute to descriptive green business research on how processes of eco‐effective greening business unfold in practical reality. I look into the case of the increasing interaction between the multinational oil company Shell and the world's largest wind turbine company Vestas. I draw on descriptive organizational sense‐making theory and analyse to this end the shared green sense‐making of Shell and Vestas on off‐shore wind energy business. The article concludes that greening companies such as Shell – that are not born green – might be considerably advanced if these companies strengthen their relationships with companies such as Vestas – that are born green. This is so since companies that are born green have strong green ecocentric business beliefs that can function as important engines in shared green sense‐making with companies that are not born green and have more hesitant green beliefs.
