Lara Rösler, Albert End, Matthias Gamer
Saliency-based models of visual attention postulate that, when a scene is freely viewed, attention is predominantly allocated to those elements that stand out in terms of their physical properties. However, eye-tracking studies have shown that saliency models fail to predict gaze behavior accurately when social information is included in an image. Notably, gaze pattern analyses revealed that depictions of human beings are heavily prioritized independent of their low-level physical saliency. What remains unknown, however, is whether the prioritization of such social features is a reflexive or a voluntary process...

One of the main Mycoplasma hyopneumoniae (M. hyopneumoniae) swine experimental model objectives is to reproduce mycoplasmal pneumonia (MP). Unfortunately, experimental validated protocols to maximize the chance to successfully achieve lung lesions induced by M. hyopneumoniae are not available at the moment. Thus, the objective of this work was to identify those factors that might have a major influence on the effective development of MP, measured as macroscopic lung lesions, under experimental conditions. Data from 85 studies describing M...

OBJECTIVE: To demonstrate the difference in organ-preservation rates and avoidance of definitive surgery among cT2N0 rectal cancer patients undergoing 2 different chemoradiation (CRT) regimens. BACKGROUND: Patients with cT2N0 rectal cancer are more likely to develop complete response to neoadjuvant CRT. Organ preservation has been considered an alternative treatment strategy for selected patients. Radiation dose-escalation and consolidation chemotherapy have been associated with increased rates of response and may improve chances of organ preservation among these patients...

Learning by watching others can provide valuable information with adaptive consequences, such as identifying the presence of a predator or locating a food source. The extent to which nonhuman animals can gain information by reading the cues of others is often tested by evaluating responses to human gestures, such as a point, and less often evaluated by examining responses to conspecific cues. We tested whether ten brown capuchin monkeys (Cebus [Sapajus] apella) were able to use cues from monkeys and a pointing cue from a human to obtain hidden rewards...

BACKGROUND: Low recurrence rates and long term survival are the main therapeutic goals of rectal cancer surgery. Complete, margin- negative resection confers the greatest chance for a cure. The aim of our study was to determine whether the length of the distal resection margin was associated with local recurrence rate and long- term survival. PATIENTS AND METHODS: One hundred and nine patients, who underwent sphincter-preserving resection for locally advanced rectal cancer after preoperative chemoradiotherapy between 2006 and 2010 in two tertiary referral centres were included in the study...

A full-term female baby born to parents who gave birth three years prior to a girl who survived only 31h postpartum died 36h after birth. An autopsy showed that the heart was markedly hypertrophic (32g). Microscopically, the myocardium, liver and kidney cells exhibited extensive vacuolar degeneration. Sudan III staining was positive in cardiac muscle, liver and kidney tissue. Tandem mass spectrometry analysis revealed that the deceased patient had a carnitine palmitoyl transferase II (CPT2) deficiency or a carnitine-acylcarnitine translocase deficiency...

BACKGROUND: When electronic anesthesia records are compared to pharmacy transactions, discrepancies in total doses of controlled drugs are commonly found (≈16% of cases), potentially affecting patient safety and placing hospitals at risk for regulatory action. Errors (≈5%) persisted even with near real-time drug reconciliation feedback to providers. A study was conducted to test the hypothesis of greater risks of discrepancy for longer-duration cases and for intraoperative handoff involving a permanent handoff of care...

Spinocerebellar ataxia (SCA) is an autosomal dominant neurodegenerative disorder characterized by slowly progressive cerebellar dysfunction. Currently, 42 SCA types are known, some of which are caused by CAG repeat expansions, but others are caused by point mutations or deletions. Spinocerebellar ataxia type 14 (SCA14) is caused by missense mutations or deletions in the PRKCG gene, coding for protein kinase C gamma (PKCγ). It is still not well understood how these mutations eventually cause Purkinje cell dysfunction and death...

BACKGROUND: Myocardial Infarction with Non-Obstructive Coronary Arteries (MINOCA) is common with a prevalence of 6% of all patients fulfilling the diagnosis of myocardial infarction. MINOCA should be considered a working diagnosis. Cardiac Magnetic Resonance (CMR) imaging has recently been suggested to be of great value to determine the cause behind MINOCA. The objectives of this paper are to describe the rationale behind the second Stockholm Myocardial Infarction with Normal Coronaries (SMINC-2) study and to discuss the protocol for investigation of MINOCA patients in the light of the recently published position paper from the European Society of Cardiology...

The German Transplant Law is the legal basis of the liver allocation system in Germany and is specified by the guidelines of the German Medical Association. These guidelines are based on current medical knowledge. The procedure of developing these guidelines was formalised and made transparent.This survey with 502 participants examines how four current aspects of the allocation system are perceived by different stakeholders (medical staff, patients on the liver transplant list or already transplanted, medical students and non-medical university personnel and students)...

Listeners can recognize newly learned voices from previously unheard utterances, suggesting the acquisition of high-level speech-invariant voice representations during learning. Using functional magnetic resonance imaging (fMRI) we investigated the anatomical basis underlying the acquisition of voice representations for unfamiliar speakers independent of speech, and their subsequent recognition among novel voices. Specifically, listeners studied voices of unfamiliar speakers uttering short sentences and subsequently classified studied and novel voices as "old" or "new" in a recognition test...

Neuropeptide Y (NPY) is a member of the pancreatic peptide family of neuropeptides that play a crucial role in numerous central and peripheral nervous system responses. Recently, it has been shown that NPY protects cells against neurotoxic damage from β-amyloid peptides (Aβ) in Alzheimer's disease (AD). Heme is a common factor linking several metabolic perturbations in AD and altered heme metabolism has been shown to be related to the pathologies of AD. Thus, heme may have a chance to act on NPY and potentially counteract its function...

This study examined the influence of tactical and situational variables on offensive sequences during elite football matches. A sample of 68 games and 1694 offensive sequences from the Spanish La Liga, Italian Serie A, German Bundesliga, English Premier League and Champions League were analysed using chi-square and logistic regression analyses. Results revealed that counterattacks (OR=1.44; 95% CI: 1.13 to 1.83; P<0.01) and fast attacks (OR=1.43; 95% CI: 1.11 to 1.85; P<0.01) increased the success of an offensive sequence by 40% compared with positional attacks...

What do experimentally measured kinetic isotope effects (KIEs) tell us about H-abstraction reactions with multi-spin-state reactivity options? Using DFT calculations with tunneling corrections for experimentally studied H-abstraction reactions of porphyrin-Compound II species (Chem. - Eur. J. 2014, 20, 14437; Angew. Chem., Int. Ed. 2008, 47, 7321) with cyclohexane, dihydroanthracene (DHA), and xanthene (Xan), we show here that KIE is a selective probe that identifies the experimentally reactive spin state. At the same time, comparison of calculated and experimental KIE values permits us to determine the structural orientation of the transition states, as well as the presence/absence of an axial ligand, and the effect of porphyrin substituents...

Genomic prediction utilizing causal variants could increase selection accuracy above that achieved with SNPs genotyped by currently available arrays used for genomic selection. A number of variants detected from sequencing influential sires are likely to be causal, but noticeable improvements in prediction accuracy using imputed sequence variant genotypes have not been reported. Improvement in accuracy of predicted breeding values may be limited by the accuracy of imputed sequence variants. Using genotypes of SNPs on a high-density array and non-synonymous SNPs detected in sequence from influential sires of a multibreed population, results of this examination suggest that linkage disequilibrium between non-synonymous and array SNPs may be insufficient for accurate imputation from the array to sequence...

BACKGROUND: Higher rates of local recurrences and second primaries, ascribable to field cancerization, are known problem in oral cancers. The present study explored utility of identification of potential recurrences by Raman spectroscopy, which has been shown to identify oral precancers, cancers, and field cancerization in humans and micro-sized mechanical irritation-induced tumors in animals. METHODS: Raman spectra were acquired from tumor and contralateral normal mucosa in 99 patients with oral cancer who were then followed up for appearance of clinically apparent cancerous lesions...
