Crosstalk is one of the most severe factors affecting the perceived quality of stereoscopic 3D (S3D) images. It arises from a leakage of light intensity between multiple views, as in auto-stereoscopic displays. Well-known determinants of crosstalk include the co-location contrast and disparity of the left and right images, which have been dealt with in prior studies. However, when a natural stereo image that contains complex naturalistic spatial characteristics is viewed on an auto-stereoscopic display, other factors may also play an important role in the perception of crosstalk...

Tourette syndrome (TS) is a model neuropsychiatric disorder thought to arise from abnormal development and/or maintenance of cortico-striato-thalamo-cortical circuits. TS is highly heritable, but its underlying genetic causes are still elusive, and no genome-wide significant loci have been discovered to date. We analyzed a European ancestry sample of 2,434 TS cases and 4,093 ancestry-matched controls for rare (< 1% frequency) copy-number variants (CNVs) using SNP microarray data. We observed an enrichment of global CNV burden that was prominent for large (> 1 Mb), singleton events (OR = 2...

OBJECTIVES: : Small aortic annuli are challenging in aortic valve replacement. Prosthesis-patient mismatch, accompanied by high transvalvular gradients and small orifice area, is an often faced problem impairing postoperative outcome. The new TRIBIO bioprosthesis aims to enable enhanced haemodynamics, being increasingly important with decreasing annular size. This study compares ex vivo hydrodynamics of TRIBIO with 2 established bioprostheses in small annuli at different stroke volumes, simulating 'rest' and 'exercise', and evaluates haemodynamics of TRIBIO in a sheep model...

Esophageal duplication cyst is a rare congenital gastrointestinal malformation. It is the second most common duplication cyst following small bowel duplication cyst in the gastrointestinal tract. Patients with an esophageal duplication cyst are generally asymptomatic; however, some patients may present the following symptoms: dysphagia, chest pain, stridor, unproductive cough, and epigastric discomfort by compression of the surrounding structures. Surgical removal is the treatment of choice in symptomatic cases and can be considered in asymptomatic cases if they are at risk for developing complications, such as ulceration or perforation...

BACKGROUND: Patient-reported outcome measures (PROMs) can provide valuable information which may assist with the care of patients with chronic kidney disease (CKD). However, given the large number of measures available, it is unclear which PROMs are suitable for use in research or clinical practice. To address this we comprehensively evaluated studies that assessed the measurement properties of PROMs in adults with CKD. METHODS: Four databases were searched; reference list and citation searching of included studies was also conducted...

Triple-negative breast cancer (TNBC) cells do not express estrogen receptors, progesterone receptors, or human epidermal growth factor receptor 2. Currently, apart from poly ADP-ribose polymerase inhibitors, there are few effective therapeutic options for this type of cancer. Here, we present comprehensive characterization of the genetic alterations in TNBC performed by high coverage whole genome sequencing together with transcriptome and whole exome sequencing. Silencing of the BRCA1 gene impaired the homologous recombination pathway in a subset of TNBCs, which exhibited similar phenotypes to tumors with BRCA1 mutations; they harbored many structural variations (SVs) with relative enrichment for tandem duplication...

OBJECTIVE: Mutations in the aryl hydrocarbon receptor-interacting protein (AIP) gene are associated with pituitary adenoma, acromegaly and gigantism. Identical alleles in unrelated pedigrees could be inherited from a common ancestor or result from recurrent mutation events. DESIGN & METHODS: Observational, inferential and experimental study, including: AIP mutation testing; reconstruction of 14 AIP-region (8.3 Mbp) haplotypes; coalescent-based approximate Bayesian estimation of the time to most recent common ancestor (tMRCA) of the derived allele; forward population simulations to estimate current number of allele carriers; proposal of mutation mechanism; protein structure predictions; co-immunoprecipitation and cycloheximide chase experiments...

The family Polyomaviridae encompasses non-enveloped viruses with a circular dsDNA genome that is typically approximately 5000bp in length. Originally isolated from mammals, polyomavirus sequences have now been detected in invertebrates, fish, amphibians, reptiles and birds, although it remains to be determined whether all these animals are genuine hosts. The genomes of all polyomaviruses encode at least two regulatory proteins (large and small tumour antigen) and two structural proteins (capsid proteins VP1 and VP2) whose functions have been defined...

Stony coral (Scleractinia) genomes are still poorly explored and many questions remain about their evolution and contribution to the success and longevity of reefs. We analyzed transcriptome and genome data from Montipora capitata, Acropora digitifera, and transcriptome data from 20 other coral species. To our surprise, we found highly conserved, anciently derived, Scleractinia COral-specific Repeat families (SCORs) that are abundant in all the studied lineages. SCORs form complex secondary structures and are located in untranslated regions and introns, but most abundant in intergenic DNA...

Gene replacement is one of the most essential approaches in construction of the genetically modified yeast strains. However, the fidelity of gene targeting and the effort needed for construction of a particular strain can vary significantly. We investigated the influence of two important factors-the choice of the transformation method and the design of the transforming DNA fragment, which can vary in overall length (including flanking regions and selectable marker) compared to the length of the targeted region in the genome...

In bilaterian animals the 3' ends of microRNAs (miRNAs) are frequently modified by tailing and trimming. These modifications affect miRNA-mediated gene regulation by modulating miRNA stability. Here we analyzed data from three non-bilaterian animals: two cnidarians (Nematostella vectensis and Hydra magnipapillata) and one poriferan (Amphimedon queenslandica). Our analysis revealed that non-bilaterian miRNAs frequently undergo modifications like the bilaterian counterparts: the majority are expressed as different length isoforms and frequent modifications of the 3' end by mono U or mono A tailing are observed...

Gene duplication is an important source of novelties and genome complexity. What genes are preserved as duplicated through long evolutionary times can shape the evolution of innovations. Identifying factors that influence gene duplicability is therefore an important aim in evolutionary biology. Here, we show that in the yeast Saccharomyces cerevisiae the levels of gene expression correlate with gene duplicability, its divergence, and transcriptional plasticity. Genes that were highly expressed before duplication are more likely to be preserved as duplicates for longer evolutionary times and wider phylogenetic ranges than genes that were lowly expressed...

PURPOSE: Temporal lobe epilepsy (TLE) is the most common form of focal epilepsy and may be associated with acquired central nervous system lesions or could be genetic. Various susceptibility genes and environmental factors are believed to be involved in the aetiology of TLE, which is considered to be a heterogeneous, polygenic, and complex disorder. Rare point mutations in LGI1, DEPDC5, and RELN as well as some copy number variations (CNVs) have been reported in families with TLE patients...

Prior to mitosis, duplicated centrosomes are tethered together, which is thought to prevent mitotic defects. A new study establishes the role of tetrameric Kif25, a microtubule minus-end-directed kinesin-14 motor, in preventing premature centrosome separation through a microtubule-dependent pathway.

BACKGROUND: Managing children is a challenge that many dentists face. Many non-pharmacological techniques have been developed to manage anxiety and behavioural problems in children, such us: 'tell, show & do', positive reinforcement, modelling and hypnosis. The use of hypnosis is generally an overlooked area, hence the need for this review. OBJECTIVES: This systematic review attempted to answer the question: What is the effectiveness of hypnosis (with or without sedation) for behaviour management of children who are receiving dental care in order to allow successful completion of treatment?Null hypothesis: Hypnosis has no effect on the outcome of dental treatment of children...
