“An illusion of rapid movement is normally perceived when an attentional cue (such as a peripheral flash) preceeds the onset of a line. The movement is perceived as receding away from the cue. This study investigated how this illusion was perceived by people with schizophrenia. Nineteen participants with schizophrenia and 26 healthy matched controls were presented with a series of real, illusory,

no motion or combined real and illusory motion stimuli at various target speeds. Detection thresholds were measured to determine the reliability of motion perception. The participants with schizophrenia were not distinguished from the control group in the perception of real motion. However, the motion detection curves for the selleck kinase inhibitor schizophrenia group revealed a reduction in the perceptual effect of illusory motion in comparison

to controls. The findings revealed that people with schizophrenia may be less easily deceived by illusory motion in comparison to healthy participants. (C) 2010 Elsevier Ltd. All rights reserved.”
“Since its initial identification in Mexico and the United States, concerns have been raised that the novel H1N1 influenza virus might cause a pandemic of severity comparable to that of the 1918 pandemic. In late April 2009, viruses phylogenetically related to pandemic H1N1 influenza virus were isolated from an selleck chemicals llc outbreak on a Canadian pig farm. This outbreak also had epidemiological links to a suspected human case. Experimental infections carried out in pigs using one of the swine isolates from this outbreak and the human isolate A/Mexico/InDRE4487/2009 showed differences in virus recovery from the lower respiratory tract. Virus was consistently isolated from Orotic acid the lungs of pigs infected with A/Mexico/InDRE4487/2009,

while only one pig infected with A/swine/Alberta/OTH-33-8/2008 yielded live virus from the lung, despite comparable amounts of viral RNA and antigen in both groups of pigs. Clinical disease resembled other influenza virus infections in swine, albeit with somewhat prolonged virus antigen detection and delayed viral-RNA clearance from the lungs. There was also a noteworthy amount of genotypic variability among the viruses isolated from the pigs on the farm. This, along with the somewhat irregular pathobiological characteristics observed in experimentally infected animals, suggests that although the virus may be of swine origin, significant viral evolution may still be ongoing.”
“A growing body of literature demonstrates impaired multisensory integration (MSI) in patients with schizophrenia compared to non-psychiatric individuals. One of the most basic measures of MSI is intersensory facilitation of reaction times (RTs), in which bimodal targets, with cues from two sensory modalities, are detected faster than unimodal targets. This RT speeding is generally attributed to super-additive processing of multisensory targets.
