Tanja M Gerlach, Ruben C Arslan, Thomas Schultze, Selina K Reinhard, Lars Penke
Although empirical research has investigated what we ideally seek in a romantic partner for decades, the crucial question of whether ideal partner preferences actually guide our mating decisions in real life has remained largely unanswered. One reason for this is the lack of designs that assess individuals' ideal partner preferences before entering a relationship and then follow up on them over an extended period. In the Göttingen Mate Choice Study (GMCS), a preregistered, large-scale online study, we used such a naturalistic prospective design...

BACKGROUND: Intravenous (IV) iron in pregnancy is useful where oral iron is not tolerated or a rapid replenishment of iron is required. AIMS: To review the literature on the efficacy and safety of different IV iron preparations in the management of antenatal iron-deficiency anaemia (IDA). MATERIALS AND METHODS: We searched MEDLINE, Embase and Scopus from inception to June 2016. Eligible studies were randomised controlled trials (RCTs) and observational studies, involving administration of IV iron (ferric carboxymaltose (FCM), iron polymaltose (IPM) or iron sucrose (IS)), regardless of comparator, to manage antenatal IDA...

BACKGROUND: Novel surgical approach to repair degenerative mitral regurgitation such as transapical chordae tendineae replacement and "loop in loop" in loop techniques, need of artificial chordae longer than that used in the older techniques of chordae tendineae replacement. This difference in length has been reported as potential critical point for durability of artificial chordae. In the present paper we have investigated the elastic behavior of different diameter and length politetrafluorene (PTFE) suture threads as substitute of native chordae, to identify their reliability to use as long artificial chordae...

Foot-and-mouth disease (FMD) poses a serious threat to the agricultural sector due to its highly contagious nature. Outbreaks of FMD can lead to substantial disruptions to livestock markets due to loss of production and access to international markets. In a previously FMD-free country, the use of vaccination to augment control of an FMD outbreak is increasingly being recognized as an alternative control strategy to direct slaughtering [stamping-out (SO)]. The choice of control strategy has implications on production, trade, and hence prices of the sector...

Mycobacteria are subdivided into three groups: the Mycobacterium tuberculosis complex, the non-tuberculous mycobacteria called NTM or MOTT (Mycobacteria Other Than Tuberculosis) and Mycobacterium leprae. Over the past few decades, the incidence of infections caused by NTM has increased world wide. The differentiation of Mycobacterium tuberculosis complex from NTM is of primary importance for infection control and choice of antimicrobial therapy. However, there is so far no report in Bangladesh about the detection of NTM and hence differentiation of MTB and NTM...

BACKGROUND: Deep infection following arthroplasty remains a devastating complication. Some registry data suggests that modern positive-pressure surgical helmet systems (SHS) are associated with a paradoxical increase in infection rates, and as such their role in arthroplasty remains unclear. The aim of this study was to investigate whether SHS increase wound contamination in total knee arthroplasty (TKA) and if this contamination can be reduced by placing tape around the gown/glove interface...

Secondary neuronal degeneration (SND) occurring in Traumatic brain injury (TBI) consists in downstream destructive events affecting cells that were not or only marginally affected by the initial wound, further increasing the effects of the primary injury. Glutamate excitotoxicity is hypothesized to play an important role in SND. TBI is a common cause of olfactory dysfunction that may be spontaneous and partially recovered. The role of the glutamate excitotoxicity in the TBI-induced olfactory dysfunction is still unknown...

Previous studies have used principal component analysis (PCA) to investigate the craniofacial relationship, as well as sex determination using facial factors. However, few studies have investigated the extent to which the choice of principal components (PCs) affects the analysis of craniofacial relationship and sexual dimorphism. In this paper, we propose a PCA-based method for visual and quantitative analysis, using 140 samples of 3D heads (70 male and 70 female), produced from computed tomography (CT) images...

Sun Hee Yim, Ryuta Tobe, Anton A Turanov, Bradley A Carlson
The trace element selenium (Se) is incorporated into proteins as the amino acid selenocysteine (Sec), which is cotranslationally inserted into specific proteins in response to a UGA codon. Proteins containing Sec at these specific positions are called selenoproteins. Most selenoproteins function as oxidoreductases, while some serve other important functions. There are 25 known selenoprotein genes in humans and 24 in mice. The use of Sec allows selenoproteins to be detected by a convenient method involving metabolic labeling with (75)Se...

#11
Christina B Reimer, Torsten Schubert
Both response selection and visual attention are limited in capacity. According to the central bottleneck model, the response selection processes of two tasks in a dual-task situation are performed sequentially. In conjunction search, visual attention is required to select the items and to bind their features (e.g., color and form), which results in a serial search process. Search time increases as items are added to the search display (i.e., set size effect). When the search display is masked, visual attention deployment is restricted to a brief period of time and target detection decreases as a function of set size...

Cognition is one of the most flexible tools enabling adaptation to environmental variation. Living close to humans is thought to influence social as well as physical cognition of animals throughout domestication and ontogeny. Here, we investigated to what extent physical cognition and two domains of social cognition of dogs have been affected by domestication and ontogeny. To address the effects of domestication, we compared captive wolves (n = 12) and dogs (n = 14) living in packs under the same conditions...

Hard polyhedra are a natural extension of the hard sphere model for simple fluids, but no general scheme exists for predicting the effect of shape on thermodynamic properties, even in fluids of moderate density. Only the second virial coefficient is known analytically for general convex shapes, so higher order equations of state have been elusive. Here we investigate high-precision state functions in the fluid phase of 14 representative polyhedra with different assembly behaviors. We discuss historic efforts in analytically approximating virial coefficients up to $B_4$ and numerically evaluating them to $B_8$ Using virial coefficients as inputs, we show the convergence properties for four equations of state for hard convex bodies...

Proton magnetic resonance spectroscopy ((1) H-MRS) can be used to quantify in vivo metabolite levels, such as lactate, γ-aminobutyric acid (GABA) and glutamate (Glu). However, there are considerable analysis choices which can alter the accuracy or precision of (1) H-MRS metabolite quantification. It is currently unknown to what extent variations in the analysis pipeline used to quantify (1) H-MRS data affect outcomes. The purpose of this study was to evaluate whether the quantification of identical (1) H-MRS scans across independent and experienced research groups would yield comparable results...

BACKGROUND: With the number of available dermal fillers increasing, so is the demand for scientifically based comparisons, often with rheological properties in focus. Since analytical results are always influenced by instrument settings, consensus on settings is essential to make comparison of results from different investigators more useful. OBJECTIVE: Preferred measurement settings for rheological analysis of hyaluronic acid (HA) fillers are suggested, and the reasoning behind the choices is presented by demonstrating the effect of different measurement settings on select commercial HA fillers...

We investigate polarization-insensitive waveguide designs afforded by the interplay of material and waveguide birefringence in LiNbO3-on-insulator photonic wires. Fundamental mode birefringence-free operation in the 0.8-1.8 μm spectral range is predicted for a suitable choice of waveguide widths in the 375-600 nm range. Optimized buried waveguide designs yield broadband (1350-1625 nm) index matching between TE00 and TM00 modes. Furthermore, simultaneous phase- and group-velocity matching at infrared wavelengths appears feasible for pulse durations as short as 100 fs...

The ability to identify stimuli that signal important events is fundamental for an organism to adapt to its environment. In the present paper, we investigated how more than one stimulus could be used jointly to learn a temporal discrimination task. Ten pigeons were exposed to a symbolic matching-to-sample procedure with three durations as samples (2, 6, and 18 s of keylight) and two colors as comparisons (red and green hues). A 30-s intertrial interval (ITI), illuminated with a houselight, separated the trials...

REVIEW
Ioana Agache, Liliana Rogozea
Measurement of biomarkers has been incorporated within clinical research of asthma to characterize the population and to associate the disease with environmental and therapeutic effects. Regrettably, at present, there are no specific biomarkers, none is validated or qualified, and endotype-driven choices overlap. Biomarkers have not yet reached clinical practice and are not included in current asthma guidelines. Last but not least, the choice of the outcome upholding the value of the biomarkers is extremely difficult, since it has to reflect the mechanistic intervention while being relevant to both the disease and the particular person...

Muscle synergy analysis (MSA) is a mathematical technique that reduces the dimensionality of electromyographic (EMG) data. Used increasingly in biomechanics research, MSA requires methodological choices at each stage of the analysis. Differences in methodological steps affect the overall outcome, making it difficult to compare results across studies. We applied MSA to EMG data collected from individuals post-stroke identified as either responders (RES) or non-responders (nRES) on the basis of a critical post-treatment increase in walking speed...

Treatment intensification to maximize disease control and reduced-intensity approaches to minimize the risk of late sequelae have been evaluated in newly diagnosed Hodgkin lymphoma. The influence of these interventions on the risk of secondary malignant neoplasms, progression-free survival and overall survival is reported in the present meta-analysis based on individual patient data from 9498 patients treated within 16 randomized controlled trials for newly diagnosed Hodgkin lymphoma between 1984 and 2007. Secondary malignant neoplasms were meta-analyzed using Peto's method as time-to-event outcomes...
