Patients with Lewy body disease (LBD) frequently experience visual hallucinations (VH), well-formed images perceived without the presence of real stimuli. The structural and functional brain mechanisms underlying VH in LBD are still unclear. The present review summarises the current literature on the neural correlates of VH in LBD, namely Parkinson's disease (PD), and dementia with Lewy bodies ...

In Heterodontus, a phylogenetically primitive shark species, the variable (VH), diversity (DH), joining (JH) segments, and constant (CH) exons are organized in individual approximately 18-20-kb "clusters." A single large VH family with > 90% nucleic acid homology and a monotypic second gene family are identified by extensive screening of a genomic DNA library. Little variation in the nucleotide...

The stability and accuracy of a streamline diffusion finite element method (SDFEM) on arbitrary grids applied to a linear 1-d singularly perturbed problem are studied in this paper. With a special choice of the stabilization quadratic bubble function, the SDFEM is shown to have an optimal second order in the sense that ‖u − uh‖∞ ≤ C infvh∈V h ‖u − vh‖∞, where uh is the SDFEM approximation of th...

Purpose The purpose of this article is to examine the ability of an acoustic measure, relative fundamental frequency (RFF), to distinguish between two subtypes of vocal hyperfunction (VH): phonotraumatic (PVH) and non-phonotraumatic (NPVH). Method RFF values were compared among control individuals with typical voices (N = 49), individuals with PVH (N = 54), and individuals with NPVH (N = 35)....

Three different populations of voltage-activated K+ channels were identified according to their voltage-dependences, inactivation kinetics and sensitivity toward selective K+ channels antagonists in membranes of cells, isolated from the circular layer of guinea-pig ileum by the use of whole-cell voltage clamp method. Under holding potential Vh = -50 mV apamin (10-6 mol/l) inhibited 29 +/- 3% of...

Abstract Marine pollution is one of issues that widely discussed such as marine debris, chemical contamination, and oil spill. It has many impacts on the environment. Remote sensing helps detect presence an spill via satellite platform. One commonly used Synthetic-Aperture Radar (SAR) imagery, which can see spills even in cloudy conditions. However, black white appearance radar sometimes makes ...

Patients with schizophrenia have altered visual cognition and retinal functions. No studies explored if anomalies are related to the presence of hallucinations (VH). We functional responses ganglion cells in patients or without VH conducted a neuropsychological evaluation explore links between function. The VH+ group showed poorer we found correlations amplitudes P50 N95 waves cognition. Our re...

PURPOSE To assess the impact of very hot (45°C) conditions on the performance of, and physiological responses to, a simulated firefighting manual-handling task compared to the same work in a temperate environment (18°C). METHODS Ten male volunteer firefighters performed a 3-h protocol in both 18°C (CON) and 45°C (VH). Participants intermittently performed 12 × 1-min bouts of raking, 6 × 8-min...

BACKGROUND Previously, we have reported that daily glucose fluctuations could affect coronary plaque vulnerability, but the underlying mechanisms remained unclear. This study sought to investigate the impact of CD14++CD16+ monocytes on plaque vulnerability, as assessed by virtual histology intravascular ultrasound (VH-IVUS), as well as their relationship to fluctuating glucose levels in patient...

What happens when a Virtual Human makes a mistake? In this study we investigate the impact of a VH’s conversational mistakes in the context of persuasion. Users interacted with a VH that told persuasive information, and they were given the option to use the information to complete a problem-solving task. The VH occasionally made mistakes such as not responding, repeating the same answer, or giv...
