Plasma Polarization in High Gravity Astrophysical Objects
Authors: Iosilevskiy I. 
Published: December 2009

AbstractMacroscopic plasma polarization, which is created by gravitation and other mass‐acting (inertial) forces in massive astrophysical objects (MAO) is under discussion. Non‐ideality effect due to strong Coulomb interaction of charged particles is introduced into consideration as a new source of such polarization. Simplified situation of totally equilibrium isothermal star without relativistic effects and influence of magnetic field is considered. The study is based on variational approach combined with “local density approximation”. It leads to two local forms of thermodynamic equilibrium conditions: constancy for generalized (electro)chemical potentials and/or conditions of equilibrium for the forces acting on each charged specie. New “non‐ideality potential” and “non‐ideality force” appear naturally in this consideration. Hypothetical sequences of gravitational, inertial and non‐ideality polarization on thermo‐ and hydrodynamics of MAO are under discussion (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

Social function in multiple X and Y chromosome disorders: XXY, XYY, XXYY, XXXY
Authors: Visootsak Jeannie , Graham John M. 
Published: December 2009

AbstractKlinefelter syndrome (47,XXY) was initially described in the context of its endocrinologic and physical features; however, subsequent studies have revealed specific impairments in verbal skills and social functioning. Males with sex chromosomal aneuploidies are known to have variability in their developmental profile with the majority presenting with expressive language deficits. As a consequence of language delays, they have an increased likelihood of language‐based learning disabilities and social‐emotional problems that may persist through adulthood. Studies on males with 47,XXY have revealed unique behavioral and social profiles with possible vulnerability to autistic traits. The prevalence of males with more than one extra sex chromosome (e.g., 48,XXYY and 48,XXXY) and an additional Y (e.g., 47,XYY) is less common, but it is important to understand their social functioning as it provides insight into treatment implications. © 2009 Wiley‐Liss, Inc.

Gene, brain, and behavior relationships in fragile X syndrome: Evidence from neuroimaging studies
Authors: Lightbody Amy A. , Reiss Allan L. 
Published: December 2009

AbstractFragile X syndrome (FraX) remains the most common inherited cause of intellectual disability and provides a valuable model for studying gene‐brain‐behavior relationships. Over the past 15 years, structural and functional magnetic resonance imaging studies have emerged with the goal of better understanding the neural pathways contributing to the cognitive and behavioral outcomes seen in individuals with FraX. Specifically, structural MRI studies have established and begun to refine the specific topography of neuroanatomical variation associated with FraX. In addition, functional neuroimaging studies have begun to elucidate the neural underpinnings of many of the unique characteristics of FraX including difficulties with eye gaze, executive functioning, and behavioral inhibition. This review highlights studies with a focus on the relevant gene‐brain‐behavior connections observed in FraX. The relationship of brain regions and activation patterns to FMRP are discussed as well as the clinical cognitive and behavioral correlates of these neuroimaging findings. © 2009 Wiley‐Liss, Inc.

Cognitive profile of Turner syndrome
Authors: Hong David , Scaletta Kent Jamie , Kesler Shelli 
Published: December 2009

AbstractTurner syndrome (TS) is a relatively common neurogenetic disorder characterized by complete or partial monosomy‐X in a phenotypic female. TS is associated with a cognitive profile that typically includes intact intellectual function and verbal abilities with relative weaknesses in visual–spatial, executive, and social cognitive domains. In this report, we review previous and current research related to the cognitive profile of TS. We also discuss how cognitive impairments in this syndrome may reflect integrative rather than modular deficits. For example, the less commonly reported areas of verbal difficulty in TS and certain visual–spatial deficits seem significantly influenced by impairments in executive function and spatially loaded stimuli. We provide a summary of cognitive testing measures used in the assessment of visual–spatial and executive skills, which includes test domain descriptions as well as a comprehensive examination of social cognitive function in TS. This review concludes with a discussion of ecological interpretations regarding the meaning of cognitive deficits in TS at the individual level. © 2009 Wiley‐Liss, Inc.

Structural and functional neuroimaging in Klinefelter (47,XXY) syndrome: A review of the literature and preliminary results from a functional magnetic resonance imaging study of language
Authors: Steinman Kyle , Ross Judith , Lai Song , Reiss Allan , Hoeft Fumiko 
Published: December 2009

AbstractKlinefelter (47,XXY) syndrome (KS), the most common form of sex‐chromosomal aneuploidy, is characterized by physical, endocrinologic, and reproductive abnormalities. Individuals with KS also exhibit a cognitive/behavioral phenotype characterized by language and language‐based learning disabilities and executive and attentional dysfunction in the setting of normal general intelligence. The underlying neurobiologic mechanisms are just now beginning to be elucidated through structural and functional neuroimaging. Here, we review the literature of structural and functional neural findings in KS identified by neuroimaging and present preliminary results from a functional magnetic resonance imaging study examining brain activity during a verb generation task in KS. © 2009 Wiley‐Liss, Inc.

Effects of sex chromosome aneuploidies on brain development: Evidence from neuroimaging studies
Authors: Lenroot Rhoshel K. , Lee Nancy Raitano , Giedd Jay N. 
Published: December 2009

AbstractVariation in the number of sex chromosomes is a relatively common genetic condition, affecting as many as 1/400 individuals. The sex chromosome aneuploidies (SCAs) are associated with characteristic behavioral and cognitive phenotypes, although the degree to which specific individuals are affected can fall within a wide range. Understanding the effects of different dosages of sex chromosome genes on brain development may help to understand the basis for functional differences in affected individuals. It may also be informative regarding how sex chromosomes contribute to typical sexual differentiation. Studies of 47,XXY males make up the bulk of the current literature of neuroimaging studies in individuals with supernumerary sex chromosomes, with a few small studies or case reports of the other SCAs. Findings in 47,XXY males typically include decreased gray and white matter volumes, with most pronounced effects in the frontal and temporal lobes. Functional studies have shown evidence of decreased lateralization. Although the hypogonadism typically found in 47,XXY males may contribute to the decreased brain volume, the observation that 47,XXX females also show decreased brain volume in the presence of normal pubertal maturation suggests a possible direct dosage effect of X chromosome genes. Additional X chromosomes, such as in 49,XXXXY males, are associated with more markedly decreased brain volume and increased incidence of white matter hyperintensities. The limited data regarding effects of having two Y chromosomes (47,XYY) do not find significant differences in brain volume, although there are some reports of increased head size.

Turner syndrome: Neuroimaging findings: Structural and functional
Authors: Mullaney Ronan , Murphy Declan 
Published: December 2009

AbstractNeuroimaging studies of Turner syndrome can advance our understanding of the X chromosome in brain development, and the modulatory influence of endocrine factors. There is increasing evidence from neuroimaging studies that TX individuals have significant differences in the anatomy, function, and metabolism of a number of brain regions; including the parietal lobe; cerebellum, amygdala, hippocampus; and basal ganglia; and perhaps differences in “connectivity” between frontal and parieto‐occipital regions. Finally, there is preliminary evidence that genomic imprinting, sex hormones and growth hormone have significant modulatory effects on brain maturation in TS. © 2009 Wiley‐Liss, Inc.

Published: December 2009

AbstractBackgroundThe metabolic syndrome consists of a cluster of cardiovascular risk factors, many of which have also been implicated in the genesis of chronic kidney disease. We studied the impact of the metabolic syndrome on chronic kidney disease in general population.MethodsThe Niigata Preventive Medicine Study was community‐based prospective observational cohort study based upon the annual health examinations in Japan. We studied the association of the metabolic syndrome with a risk of development of kidney dysfunction and proteinuria in 34 986 participants without baseline kidney disease.ResultsThe metabolic syndrome was present in 3679 subjects (11%). During a follow‐up of 5.8 years, kidney dysfunction developed in 184 subjects with metabolic syndrome (5.0%) and 746 subjects without metabolic syndrome (2.4%). The metabolic syndrome was associated with development of kidney dysfunction (hazard ratio [HR], 2.12). All of the metabolic syndrome components were associated with risk of kidney dysfunction. The risk of kidney dysfunction increased across a number of the fulfilled metabolic syndrome components. The association of metabolic syndrome with kidney dysfunction remained significant in subjects without hypertension, diabetes, or cardiovascular disease (HR, 1.99) and in those ≤60 years without hypertension, diabetes, or cardiovascular disease (HR, 2.11). The metabolic syndrome was similarly associated with the development of proteinuria in all subjects (HR, 1.67), in those without hypertension, diabetes, or cardiovascular disease (HR, 1.64) and in those ≤60 years without hypertension, diabetes, or cardiovascular disease (HR, 2.14).ConclusionsThe metabolic syndrome was associated with kidney disease even in subjects without major classical risk factors for chronic kidney disease.

EphA4 is necessary for spatially selective peripheral somatosensory topography
Authors: North H. A. , Karim A. , Jacquin M. F. , Donoghue M. J. 
Published: December 2009

AbstractSomatosensation is the primary sensory modality employed by rodents in navigating their environments, and mystacial vibrissae on the snout are the primary conveyors of this information to the murine brain. The layout of vibrissae is spatially stereotyped and topographic connections faithfully maintain this layout throughout the neuraxis. Several factors have been shown to influence general vibrissal innervation by trigeminal neurons. Here, the role of a cell surface receptor, EphA4, in directing position‐dependent vibrissal innervation is examined. EphA4 is expressed in the ventral region of the presumptive whisker pad and EphA4−/− mice lack the ventroposterior‐most vibrissae. Analyses reveal that ventral trigeminal axons are abnormal, failing to innervate emerging vibrissae, and resulting in the absence of a select group of vibrissae in EphA4−/− mice. EphA4's selective effect on a subset of whiskers implicates cell‐based signaling in the establishment of position‐dependent connectivity and topography in the peripheral somatosensory system.

TDP‐43, a neuro‐pathosignature factor, is essential for early mouse embryogenesis
Authors: Wu Lien‐Szu , Cheng Wei‐Cheng , Hou Shin‐Chen , Yan Yu‐Ting , Jiang Si‐Tse , Shen C.‐K. James 
Published: December 2009

AbstractTDP‐43 is a highly conserved and ubiquitously expressed nuclear protein. It has been implicated in the regulation of transcription, alternative splicing, translation, and neuronal plasticity. TDP‐43 has also been shown to be a disease signature protein associated with several neurodegenerative diseases including amyotrophic lateral sclerosis. However, the correlation of the physiological functions of TDP‐43 with these diseases remains unknown. We have used the gene targeting approach to disrupt the expression of TDP‐43 in mouse. Loss of the TDP‐43 expression results in peri‐implantation lethality of mice between embryonic days (E) 3.5 and 6.5. Blastocysts of the homozygous Tardbp null mutants are morphologically normal, but exhibit defective outgrowth of the inner cell mass in vitro. Our data demonstrate the essential function of TDP‐43 in peri‐implantation stage during the embryo development, likely because of its involvement in multiple biological processes in a variety of cell types. genesis 48:56–62, 2010. © 2009 Wiley‐Liss, Inc.
Genomic localization of the Z/EG transgene in the mouse genome
Authors: Colombo Sophie , Kumasaka Mayuko , Lobe Corrinne , Larue Lionel 
Published: December 2009

AbstractThe Z/EG transgenic mouse line, produced by Novak et al., displays tissue‐specific EGFP expression after Cre‐mediated recombination. The autofluorescence of EGFP allows the visualization of cells of interest displaying Cre recombination. The initial construct was designed such that cells without Cre recombination express the β‐galactosidase marker, facilitating counterselection. We used inverse PCR to identify the site of integration of the Z/EG transgene, to improve the efficiency of homozygous Z/EG mouse production. Recombined cells produced large amounts of EGFP protein, resulting in higher levels of fluorescence and therefore greater contrast with nonrecombined cells. We mapped the transgene to the G1 region of chromosome 5. This random insertion was found to have occurred 230‐bp upstream from the start codon of the Rasa4 gene. The insertion of the Z/EG transgene in the C57BL/6 genetic background had no effect on Rasa4 expression. Homozygous Z/EG mice therefore had no obvious phenotype. genesis 48:96–100, 2010. © 2009 Wiley‐Liss, Inc.
Nanoscale Hollow Spheres of an Amphiphilic Mixed (Phthalocyaninato)(porphyrinato)europium Double‐Decker Complex
Authors: Lu Guifen , Ou Zhongping , Jiang Jianzhuang , Bian Yongzhong 
Published: December 2009

AbstractA novel amphiphilic sandwich‐type mixed (phthalocyaninato)(porphyrinato)europium double‐decker complex Eu(Pc)[T(OH)3PP] [Pc = phthalocyaninate, T(OH)3PP = 5,10,15‐tris(4‐hydroxyphenyl)‐20‐(4‐tert‐butylphenyl)porphyrinate](1) was designed, prepared, and characterized by a range of spectroscopic methods in addition to elemental analysis. By employing a solution injection method, this compound self‐assembles into nanoscale hollow spheres with an average diameter of ca. 70 nm. The hollow spherical structure was determined by transmission electronic microscopy and scanning electronic microscopy. Comparison in the electronic absorption spectrum between the aggregate and the compound itself in solution reveals the J‐aggregation packing mode of the amphiphilic double‐decker molecules in nanoscale hollow spheres. The present work represents the first example of nanoscale hollow sphere morphology self‐assembled from sandwich tetrapyrrole rare‐earth complexes.

AbstractAryl‐ or heteroaryl‐substituted aminopyridine ligands (N2HAr) react with an equimolar amount of [Y(CH2SiMe3)3(thf)2] to give yttrium(III)‐monoalkyl complexes. The process involves the deprotonation of N2HAr by a yttrium alkyl followed by a rapid and quantitative intramolecular sp2‐CH bond activation of the aryl or heteroaryl pyridine substituents. As a result, new Y complexes distinguished by rare examples of CH bond activations have been isolated and completely characterized. Selective σ‐bond metathesis reactions take place on the residual Y–alkyl bonds upon treatment with PhSiH3. Unusual binuclear metallacyclic yttrium(III)‐hydrido complexes have been obtained and characterized by NMR spectroscopy and X‐ray diffraction analysis.
Developmental profiling of postnatal dentate gyrus progenitors provides evidence for dynamic cell‐autonomous regulation
Authors: Gilley Jennifer A. , Yang Cui‐Ping , Kernie Steven G. 
Published: December 2009

AbstractThe dentate gyrus of the hippocampus is one of the most prominent regions in the postnatal mammalian brain where neurogenesis continues throughout life. There is tremendous speculation regarding the potential implications of adult hippocampal neurogenesis, though it remains unclear to what extent this ability becomes attenuated during normal aging, and what genetic changes in the progenitor population ensue over time. Using defined elements of the nestin promoter, we developed a transgenic mouse that reliably labels neural stem and early progenitors with green fluorescent protein (GFP). Using a combination of immunohistochemical and flow cytometry techniques, we characterized the progenitor cells within the dentate gyrus and created a developmental profile from postnatal day 7 (P7) until 6 months of age. In addition, we demonstrate that the proliferative potential of these progenitors is controlled at least in part by cell‐autonomous cues. Finally, to identify what may underlie these differences, we performed stem cell‐specific microarrays on GFP‐expressing sorted cells from isolated P7 and postnatal day 28 (P28) dentate gyrus. We identified several differentially expressed genes that may underlie the functional differences that we observe in neurosphere assays from sorted cells and differentiation assays at these different ages. These data suggest that neural progenitors from the dentate gyrus are differentially regulated by cell‐autonomous factors that change over time. © 2009 Wiley‐Liss, Inc.
