Cross-cultural variation in women's preferences for cues to sex- and stress-hormones in the male face

Women in the UK prefer the faces of men with low levels of the stress hormone cortisol, and the relationship is moderated by the sex hormone testosterone. In a Latvian sample, however, women's preferences were not affected by cortisol, and the interaction with testosterone differed from that of the UK. To further explore cross-cultural variation in preferences for facial cues to sex- and stress-ho

Ultrasound Backscatter Measurements of Intact Human Proximal Femurs - Relationships of ultrasound parameters with tissue structure and mineral density.

Ultrasound reflection and backscatter parameters are related to mechanical and structural properties of bone in vitro. However, the potential of ultrasound reflection and backscatter measurements has not been tested with intact human proximal femurs ex vivo. We hypothesize that ultrasound backscatter can be measured from intact femurs and that the measured backscattered signal is associated with c

The electronic structure of free aluminum clusters: Metallicity and plasmons

The electronic structure of free aluminum clusters with similar to 3-4 nm radius has been investigated using synchrotron radiation-based photoelectron and Auger electron spectroscopy. A beam of free clusters has been produced using a gas-aggregation source. The 2p core level and the valence band have been probed. Photoelectron energy-loss features corresponding to both bulk and surface plasmon exc

Size separations of starch of different botanical origin studied by asymmetrical-flow field-flow fractionation and multiangle light scattering.

Asymmetrical-flow field-flow fractionation combined with multiangle light scattering and refractive index detection has been revealed to be a powerful tool for starch characterization. It is based on size separation according to the hydrodynamic diameter of the starch components. Starch from a wide range of different botanical sources were studied, including normal starch and high-amylose and high

Culture-independent quantification of Salmonella enterica in carcass gauze swabs by flotation prior to real-time PCR

To facilitate quantitative risk assessment in the meat production chain, there is a need for culture-independent quantification methods. The aim of this study was to evaluate the use of flotation, a non-destructive sample preparation method based on traditional buoyant density centrifugation, for culture-independent quantification of intact Salmonella in pig carcass gauze swabs (100 cm(2)) prior t

Reply to commentaries

In our response, we address four themes arising from the commentaries. First, we discuss the distinction between cognition and metacognition and show how to draw it within our framework. Next, we explain how metacognition differs from social cognition. The underlying mechanisms of metacognitive development are then elucidated in terms of interaction patterns. Finally, we consider measures of metac

The predictive value of single nucleotide polymorphisms in the VEGF system to the efficacy of first-line treatment with bevacizumab plus chemotherapy in patients with metastatic colorectal cancer Results from the Nordic ACT trial

Bevacizumab and chemotherapy is a common choice for first-line treatment of metastatic colorectal cancer (mCRC). So far, no predictive markers have been identified. The aim was to investigate the possible predictive value of single nucleotide polymorphisms (SNPs) in the vascular endothelial growth factor (VEGF) system in this setting. Pre-treatment blood samples and response evaluations were avail

Thermal Behavior of Poly(L-lactide) Having Low L-Isomer Content of 94% after Compressed CO2 Treatment

The effect of compressed CO2 treatment on the thermal behavior of poly(L-lactide) (PLLA) with low L-isomer content of 94% was studied by using differential scanning calorimetry (DSC) and temperature modulated DSC. It was shown that the treated samples displayed rich thermal transition signals during DSC heating, which is differ from the PLLA having high L-isomer content, including enthalpy relaxat

Nanoparticle-based pseudostationary phases in CEC: A breakthrough in protein analysis?

This review focuses on major trends in nanoparticle-based pseudostationary phase (PSP) CEC since the publication of our previous reviews within nanoparticle-based CEC [Nilsson, C., et al., Electrophoresis 2006, 27, 76-83; Nilsson, C., et al., J. Chromatogr. A 2007, 1168, 212-224.]. Special attention is given to the development toward protein analysis, which is driven by the strong emergence of pro

Sports-related injuries in athletes with disabilities.

The number of athletes with disabilities participating in organized sports and the popularity of the Paralympic Games is steadily increasing around the world. Despite this growing interest and the fact that participation in sports places the athlete at risk for injury, there are few studies concerning injury patterns, risk factors, and prevention strategies of injuries in disabled athletes. In thi

MOONS: the Multi-Object Optical and Near-infrared Spectrograph for the VLT

MOONS (the Multi-Object Optical and Near-infrared Spectrograph) has been selected by ESO as a third-generation instrument for the Very Large Telescope (VLT). The light grasp of the large collecting area offered by the VLT (8.2m diameter), combined with the large multiplex and wavelength coverage (optical to near-IR: 0.8 -1.8 mu m) of MOONS will provide the European astronomical community with a po

Politicisation of Conditional Cash Transfers: The Case of Guatemala

This article complements existing studies on the incumbency effects of conditional cash transfers (CCTs) by analysing the principal mechanisms by which Mi Familia Progresa (MIFAPRO) in Guatemala became increasingly politicised through clientelistic vote buying and threats of programme expulsion in case of non-electoral support. It finds that MIFAPRO constitutes an emblematic case with mixed effect

Evaluation of the Overweight/Obese Child - Practical Tips for the Primary Health Care Provider: Recommendations from the Childhood Obesity Task Force of the European Association for the Study of Obesity

The prevalence of obesity among children and adolescents is on the rise. The majority of overweight or obese children are treated by primary health care providers including paediatricians, family practitioners, dieticians, nurses, and school health services - and not by specialists. The majority of obese children have no underlying medical disorder causing their obesity yet a significant proportio
