, 2006a) emphasizes the increased role and autonomy of perceptual information selleck processing in autistic cognition. Autistic abilities also involve enhanced pattern detection, which may develop through veridical mapping across isomorphic perceptual and non-perceptual structures (Mottron et al., 2009). In this paper, we elaborate veridical mapping as a specific mechanism which can explain the higher incidence of savant abilities, as well as other related phenomena, in autism. We contend that savant abilities such as hyperlexia, but also absolute pitch and synaesthesia, involve similar neurocognitive components, share the same structure and developmental course, and represent related ways

by which the perceptual brain deals with objective structures under different conditions. Plausibly, these apparently different phenomena develop through a veridical

mapping mechanism whereby perceptual information is coupled with homological data Liproxstatin-1 supplier drawn from within or across isomorphic structures. The atypical neural connectivity characteristic of autism is consistent with a developmental predisposition to veridical mapping and the resulting high prevalence of savant abilities, absolute pitch, and synaesthesia in autism.

“The highly conserved fatty acid de novo synthesis pathway in mitochondria proceeds in an acyl carrier protein-dependent manner through a discrete set of enzymes. Saccharomyces cerevisiae has served as a model for studies of mitochondrial fatty acid synthesis type II (FAS II) and as a template for identification of mammalian components. Inactivation of mitochondrial FAS II in yeast results in respiratory deficiency and loss of cytochromes. The pathway produces the octanoyl-ACP substrate

for lipoic acid synthesis, but several pieces PKC412 of evidence indicate that it is capable of the generation of longer fatty acids. A number of structures of mitochondrial FAS If enzymes have been published in the past few years, allowing for a comparison with their prokaryotic counterparts, several of which have been described as promising targets for antibiotics. Recently, novel links between mitochondrial FAS and RNA processing in yeast and vertebrates have been reported. In S. cerevisiae, deficiency in mitochondrial FAS results in failure of maturation of mitochondrial RNAse P, while, in mammals, mitochondrial 3-hydroxyacyl thioester dehydratase and the RPP14 subunit of RNase P are encoded by the same bicistronic transcript. The first publications linking mitochondrial FAS II to disease states in mammals are emerging. (C) 2009 Elsevier Ltd. All rights reserved.”
“Inflammation, oxidative damage, and platelet activation are hypothesized biological mechanisms driving the disablement process. The aim of the present study is to assess whether biomarkers representing these mechanisms predicted major adverse health-related events in older persons.
