Effect of amaranth consumption on diabetes-related biomarkers in patients with diabetes

Amaranth has been claimed as an excellent source of bioactive compounds; however, the action of these compounds has not been tested in vivo. The aim of this study was to evaluate the effect of amaranth consumption in Mexican patients with diabetes. Selected patients have been pharmacologically treated for at least five years without showing any health improvement. Patients with diabetes were divided in four groups according to their obesity degree: normal weight (n=15), overweight (n=22), obesity I (n=13), and obesity II and III (n=12). Participants consumed amaranth daily (20 g) for three months. After the trial, it was observed a decrease in weight (W) in obesity I group (85.8 to 84.2 kg) as well as a reduction of body mass index (BMI, 32.5 to 31.8 kg/m2). Levels of serum markers related with obesity such as leptin, resistin, and visfatin decreased in all groups. The cardiovascular risk biomarker plasminogen activator inhibitor 1 (PAI-1) also decreased after the three months of treatment. This study suggests that amaranth consumption, a food containing bioactive compounds, is a promising complementation for diabetes and obesity health improvements.
KROSS: mapping the Hα emission across the star formation sequence at z ≈ 1

We present first results from the KMOS (K-band Multi-Object Spectrograph) Redshift One Spectroscopic Survey, an ongoing large kinematical survey of a thousand, z ~ 1 star-forming galaxies, with VLT KMOS. Out of the targeted galaxies (~500 so far), we detect and spatially resolve Hα emission in ~90 and 77 per cent of the sample, respectively. Based on the integrated Hα flux measurements and the spatially resolved maps, we derive a median star formation rate (SFR) of ~7.0 M⊙ yr-1 and a median physical size of 〈1/2 '〉 = 5.1 kpc. We combine the inferred SFRs and effective radii measurements to derive the star formation surface densities (ΣSFR) and present a 'resolved' version of the star formation main sequence (MS) that appears to hold at subgalactic scales, with similar slope and scatter as the one inferred from galaxy-integrated properties. Our data also yield a trend between ΣSFR and Δ(sSFR) (distance from the MS) suggesting that galaxies with higher sSFR are characterized by denser star formation activity. Similarly, we find evidence for an anticorrelation between the gas phase metallicity (Z) and the Δ(sSFR), suggesting a 0.2 dex variation in the metal content of galaxies within the MS and significantly lower metallicities for galaxies above it. The origin of the observed trends between ΣSFR-Δ(sSFR) and Z-Δ(sSFR) could be driven by an interplay between variations of the gas fraction or the star formation efficiency of the galaxies along and off the MS. To address this, follow-up observations of our sample that will allow gas mass estimates are necessary.
Generalized quasilinear approximation of the interaction of convection and mean flows in a thermal annulus

In this paper, we examine the interaction of convection, rotation and mean flows in a thermal annulus. In this system, mean flows are driven by correlations induced by rotation leading to non-trivial Reynolds stresses. The mean flows act back on the convective turbulence acting as a barrier to transport. For this system, we demonstrate that the generalized quasilinear approximation (Marston et al. 2016 Phys. Rev. Lett. 116, 214501. (doi:10.1103/PhysRevLett.116.214501)) may provide a much better approximation to the complicated full nonlinear dynamics than the widely used quasilinear approximation. This result will enable the construction of more accurate statistical theories for the description of geophysical and astrophysical flows.
Encystment of the freshwater ciliate Pelagostrombidium fallax (Ciliophora, Oligotrichida) in laboratory culture

Pelagostrombidiurn fallax from surface waters of Lake Constance, Germany, was cultivated at 9°C with Rhodomonassp. as food. Flask-shaped resting cysts typical for oligotrich ciliates were frequently observed in the stock cultures. In batch culture experiments, encystment occurred at high and low food levels. Cyst formation ceased during phases of population growth, whereas enhanced encystment was recorded shortly after food had been reduced to low concentrations by clhate grazing. In any situation, only a fraction of the population encysted.
Upstream Non-Oscillatory Advection Schemes Suitable for Ocean Wave Models

The first order upstream advection scheme used in the WAM ocean wave models is known too diffusive and is responsible for the underestimation of long distance swells. High order advection schemes used in other wave models, like the 3 order ULTIMATE QUICKEST scheme in WAVEWATCH III, are 'too good' as it does not smooth out the garden sprinkler effect. The purpose of this paper is to find a suitable 2 order scheme, which reduces the 1 order diffusion but keeps enough smoothing for the discrete direction and spectral bins. Of course, it should be free from oscillations which haunt many high order schemes. The proposed upstream nonoscillatory 2 order (UNO2) scheme is adapted from the MINMOD scheme and simplified to favour vectorization on super computers. The scheme is extended to 2-D with the multidimensional advective-conservative hybrid operator (MACHO), which keeps the 2-D scheme stable under the 1-D CFL condition and eliminates time-splitting errors. The scheme has been tested in the Met Office global and regional wave models. It is more effective than the 3 order Gadd scheme used in the Met Office operational wave models and even shows better results than the old scheme. A 3 order scheme (UNO3), similar to the 3 order ULTIMATE QUICKEST scheme but replaced its flux limiter part by the UNO2 scheme, is also presented. The UNO3 scheme is of the same accuracy as the ULTIMATE QUICKEST scheme but more efficient. Two more intermediate schemes (UNO2 and UNO3) are derived from the van Leer homonic average. Classical numerical (1-D constant speed and 2-D solid rotation and deformation) tests have demonstrated that these schemes are non-oscillatory, conservative and shape-preserving. These schemes, especially the UNO2 scheme, are recommended for replacing the 1 order upstream scheme in WAM models.
Uncertain Portfolio Selection with Background Risk and Liquidity Constraint

This paper discusses an uncertain portfolio selection problem with consideration of background risk and asset liquidity. In addition, the transaction costs are also considered. The security returns, background asset return, and asset liquidity are estimated by experienced experts instead of historical data. Regarding them as uncertain variables, a mean-risk model with background risk, liquidity, and transaction costs is proposed for portfolio selection and the crisp forms of the model are provided when security returns obey different uncertainty distributions. Moreover, for better understanding of the impact of background risk and liquidity on portfolio selection, some important theorems are proved. Finally, numerical experiments are presented to illustrate the modeling idea.
Diversity and seasonal dynamics of the photoautotrophic picoplankton in Lake Balaton (Hungary)

Lake Balaton, in Hungary, is the largest shallow lake in Central Europe. This fresh water ecosystem has been well studied, including investigations of its photoautotrophic picoplankton (PPP). Previous studies revealed that picoeukaryotes could reach an extremely high abundance in winter, while picocyanobacteria are the predominant picoplankters in warmer periods, as in other lakes in the temperate zone. In addition to epifluorescence microscopy — which allows discrimination only between phycocyanin-rich picocyanobacteria, phycoerythrin-rich picocyanobacteria and picoeu - karyotic algae — we used PCR-based molecular methods to reveal the detailed genetic diversity and seasonal dynamics of the PPP in Lake Balaton for the first time. Our results show that a single inte- grated pelagic sample, taken vertically from the whole water column, may harbor a large number of picocyanobacterial genotypes including previously unidentified groups. Based on length polymor- phism analysis of the phycocyanin operon (which contains a non-coding region of variable size), the composition of picocyanobacterial communities showed significant seasonal changes and spatial variation. The relative importance of some of the operational taxonomic units (OTUs) we detected was correlated with environmental factors, such as temperature and the concentration of available nitrogen forms. The picoeukaryotic algal community of winter PPP was dominated by chlorophytes related to the group Trebouxiophyceae. The results of this study highlight the fine internal structure and dynamics of the PPP community in freshwater ecosystems — a view that is usually blurred by the lower resolution of commonly used methods, such as epifluorescence microscopy and flow cytometry.

Correction Factors for a Radio Frequency-Type Moisture Meter for Heat-Treated Wood

Moisture content (MC) has an important effect on the performance of wood in service. In an attempt to rapidly and non-destructively acquire the MC of heat-treated wood, a radio frequency-type moisture meter was used to take the MC of 170, 185, and 200 °C heat-treated Manchurian ash and Mongolian pine wood samples as well as reference (conventional kiln-dried) samples. A linear regression analysis was applied to assess the relationship between the MC values obtained using the meter and those obtained using the oven-dry method by fitting the data points according to the least squares method. From the results of the high coefficients of determination of the regression equation, it was concluded that the meter could be effectively used to obtain the MC of heat-treated wood. Finally, to ensure the simple and reliable application of the meter, the meter correction factors corresponding to each species and heat treatment temperature were calculated and listed.
Characteristics of the near-surface turbulence during a bora event

Abstract. During a bora event, the turbulence is strongly developed in the lee of the Dinaric Alps at the eastern Adriatic coast. In order to study its properties, a 3-D ultrasonic anemometer operating at 4 Hz sampling frequency was placed in the town of Senj at 13 m above ground. The strong bora case that occurred on 7 January and lasted till 11 January 2006 is analyzed here. This data set is used for evaluation of the turbulent kinetic energy, TKE, and its dissipation rate, e. The computation of e is performed using the inertial dissipation method. The empirical length scale parameter for this event is estimated with respect to e and TKE. Some considerations about defining turbulent perturbations of the bora wind velocity are also pointed out.
A contribution to understanding the ecology of the large spot barbel-sexual dimorphism , growth and population structure of Barbus balcanicus ( Actinopterygii ; Cyprinidae ) in Central Croatia

Recent morphological and genetic studies on the genus Barbus in the Danube basin area (Kotlík et al. 2002) have led to division within the Barbus petenyi species complex and description of a new species, Barbus balcanicus. As a contribution to a better understanding of ecology of this newly described species, during 2007 authors studied the age structure, growth rate and sexual dimorphism in the population from the Ilova River basin. The overall sex ratio in the population was close to expected 1:1. Age estimation of captured specimens identified males aged 0-2 years and females aged 0-3 years. Length and weight change over age shows that there is no difference in growth rate between males and females. The population age structure suggest that females live longer (3+) than males (2+), thus explaining the sexual dimorphism in the body size. Males reach sexual maturity at around 67 mm of the total length (TL) and females at approximately 82 mm TL. Mean condition factor (Kmean) for all age classes is high (~1.2-1.3) and shows similar values. The results from unpaired two-tailed t-tests for all 26 morphometric characters show statistically significant differences between males and females (p<0.001). However, when comparing the morphometric ratios, 9 out of 28 have shown statistically significant differences (6 ratios with p<0.001; 3 ratios with p<0.005).
Assessment of Urinary Bisphenol A Levels in a Sample of Obese and Non-Obese Egyptian Children

Background: Bisphenol A (BPA) is used extensively worldwide in the manufacture of plastic polymers. The environmental obesogenic hypothesis suggests that early life exposure to BPA may increase the risk for weight gain later in childhood. Objective: To investigate the relationship between urinary BPA concentrations and obesity indicators in a sample of obese and non-obese Egyptian children and adolescents. Methods: Total urinary BPA and urinary creatinine concentrations were estimated in a random sample of 166 Egyptian children and adolescents of both sexes and different social levels. Their age ranged from 6-16 years. Measurement of anthropometric parameters was performed and children were classified according to body-mass index z-score into two groups; obese and non-obese. Results: Bisphenol A was detected in all urine samples of children and adolescents with a GM 0.67ng/ml. About 77% of children had very low concentration of urinary BPA below 1.3ng/ml. No significant difference in concentrations of unadjusted urinary BPA between obese and non-obese children. The log transformed urinary BPA and the adjusted log transformed urinary BPA for urinary creatinine showed significant higher levels in non-obese children and adolescents. No correlation between obesity indices (such as BMI-z score, waist and hip circumferences) and urinary BPA could be detected. Conclusion: Egyptian children in this study were extensively exposed to BPA with wide range of variability. The association between urinary BPA concentrations and indicators of obesity could not be confirmed. Future large prospective studies with multiple measurements of BPA, detailed measures of nutrient intake and energy expenditure are greatly recommended.
Comparison study of photoacoustic and ultrasound spectrum analysis in osteoporosis detection

Osteoporosis is a progressive bone disease, which is characterized by a decrease in the bone mass and deterioration in bone micro-architecture. In theory, photoacoustic (PA) analysis has the potential to obtain the characteristics of the bone effectively. In this study, we try to compare the PA spectral analysis (PASA) method with the quantitative ultrasound (QUS) method in osteoporosis assessment. We compare the quantified parameter slope from the PASA and broadband ultrasound attenuation from QUS among different bone models, respectively. Both the simulation and ex vivo experiment results show that bone with lower bone mineral density has the higher slope in the PASA method. Our comparison study proves that the PASA method has the same efficiency as QUS in osteoporosis assessment.
Better than Me?! How Adolescents with and without Migration Background in Germany Perceive Each Others’ Performance in Class

Is the perception of academic performance among peers biased to the disadvantage of students with migration background (MB)? What role does friendship among peers play for the perception of performance differences? In a quasi-experimental study, 9th graders with and without MB attending school in Germany rated the performance of a comparison partner relative to their own performance after taking a mathematics test. Degrees of correspondence between perceived and actual performance in intragroup (both partners with or without MB) and intergroup (comparer or partner with migration background) situations were tested in multilevel analyses. In both intragroup comparison situations, students evaluated their partners’ performances benevolently. In contrast, in intergroup situations students with MB overestimated the performance of partners without MB relative to their own. Only students without MB judging partners with MB showed no such positivity bias. The pattern was replicated in the sub sample of friends, suggesting a subtle, yet powerful negative performance stereotype towards students with MB.
The Discourse of Egyptian Slogans: from ‘Long Live Sir’ to ‘Down with the Dictator’

The impetus behind this paper is to examine the nature and function of the discourse of slogans of the Egyptian revolution of 2011. This paper covers only the period between January and March 2011, referring therefore to the change of discourse during this period. This tends to demonstrate that in this period, where the Egyptian public defied dominance and hegemony the discourse became freer and democratic. This paper therefore is designed to document this particular period of the Egyptian history where freedom and democracy contributed to a healthy democratic discourse. The textual and functional analysis of these slogans reveals that the Egyptian public political discourse has changed dramatically during this period. It has shifted from a discourse of complete allegiance to the regime into a discourse of total defiance and accountability; from a discourse of ‘long live sir’ to ‘down with the dictator’. However, this was a short-lived change as the political landscape has changed drastically in Egypt after July 3, 2013. A closer examination of change of discourse during the above-mentioned period necessitates a combined textual, social, cultural and political analysis of the slogans used during the Egyptian revolution of 2011. The analysis has shown that the slogans reflect a variety of themes and a diversity of political perspectives. The political nature of some of the slogans shapes and is shaped by the political orientation of Egyptian society in the above-mentioned period. 1. Slogans in political discourse: background The study of slogans is not a new phenomenon; many scholars have examined the use of slogans in political discourse (Sharp 1984; Urdangs and Robbins 1984; Denton 1980). Others have looked at how social, cultural and political ideologies are embedded in slogans. Kaul (2010), for instance, considers slogans as part of ‘human dialogue’, where they are tailor-made to reflect the aims and aspiration of certain groups. In addition to the political ideologies of slogans, other studies have focused on the persuasive political nature of slogans and their impact on recipients, as well as their power to force change in certain contexts. In this respect, political slogans are regarded as effective means of persuasion, and a way to express political goals, raise political consciousness, and organise certain cultural attitudes (Denton 1980; McGee 1989). Furthermore, slogans can serve as a form of ‘controlling consciousness’ (McGee 1989). Such control frequently emanates from the persuasive nature of slogans, which often have a political impact on mobilizing and shaping the mind and culture of recipients. According to Condit and Lucaites (1993), social, political and ideological issues shape and are shaped by the use of slogans in the public discourse. They believe that through the analysis of slogans we can ‘gain an insight into Arab Media & Society (Issue 19, Fall 2014)
Optimal Monetary Policy Rules, Asset Prices and Credit Frictions

We study optimal monetary policy in two prototype economies with sticky prices and credit market frictions. In the first economy, credit frictions apply to the financing of the capital stock, generate acceleration in response to shocks and the ‘financial markup’ (i.e., the premium on external funds) is countercyclical and negatively correlated with the asset price. In the second economy, credit frictions apply to the flow of investment, generate persistence, and the financial markup is procyclical and positively correlated with the asset price. We model monetary policy in terms of welfare-maximizing interest rate rules. The main finding of our analysis is that strict inflation stabilization is a robust optimal monetary policy prescription. The intuition is that, in both models, credit frictions work in the direction of dampening the cyclical behaviour of inflation relative to its credit-frictionless level. Thus neither economy, despite yielding different inflation and investment dynamics, generates a trade-off between price and financial markup stabilization. A corollary of this result is that reacting to asset prices does not bear any independent welfare role in the conduct of monetary policy.
