Neurocognitive function in patients with small cell lung cancer
Authors: Grosshans David R. , Meyers Christina A. , Allen Pamela K. , Davenport Samuel D. , Komaki Ritsuko 
Published: December 2007

AbstractBACKGROUND.The use of prophylactic cranial irradiation (PCI) in patients with small cell lung cancer (SCLC) has been tempered by fears of detrimental effects on cognitive function. Neuropsychologic testing was prospectively conducted before and after PCI to evaluate its effects on cognitive function in patients with SCLC.METHODS.Ninety‐six patients who completely or partially responded to initial therapy underwent formal neurocognitive testing before PCI. Three patients who had central nervous system metastasis were excluded. Of the remaining patients, 69 received PCI (mean dose, 25 grays [Gy] in 10 fractions). Repeat testing was performed on 37 patients (median follow‐up, 23 months; range, 6–120 months).RESULTS.Baseline impairment was defined as ≥1.5 standard deviations below the normative mean. Before undergoing PCI, 47% of patients had evidence of impaired cognitive function. After PCI, univariate analysis revealed significant transient declines in executive function (pre‐PCI mean, 15.6 ± 11.5; post‐PCI, 27.1 ± 17.6 [P = .008]) and language (pre‐PCI mean, 33.8 ± 9.9; post‐PCI, 31.0 ± 9.0 [P = .049]) at early timepoints. Controlling for noncentral nervous system disease progression the deficit in executive function was no longer significant. Moreover, these deficits were not sustained, and significant improvements in language and motor coordination were recorded. On multivariate analysis, no significant differences before and after PCI were found.CONCLUSIONS.Neurocognitive testing demonstrated that a substantial portion of patients with SCLC had impaired brain functioning at baseline. Persistent declines in cognitive function were not observed after cranial irradiation. These data do not favor the omission of PCI on the basis of fears of neurotoxic effects.

Isotope and Surface Temperature Effects for Hydrogen Recombination on a Graphite Surface
Authors: Rutigliano M. , Cacciatore M. 
Published: December 2007

AbstractWe highlight the isotope and surface temperature effects for hydrogen atom recombination on a graphite surface. The reaction dynamics is studied using the semiclassical collisional method, according to which the mass and temperature effects are due to the coupling between the H/D dynamics and the dynamics of the phonon excitation/de‐excitation mechanism of the substrate. All possible collisional schemes with H/D adsorbed on the surface and H/D impinging from the gas phase are considered. In particular, we focus on the recombination reaction between an H atom colliding with a D atom adsorbed on the surface and a D atom incident on an H adatom. For H2 and D2 formation, the surface temperature effect is investigated by comparing the results obtained for TS=800 K with those obtained at TS=500 K and TS=100 K. Despite the low masses involved in the dynamics, effective isotope and temperature effects were observed on the recombination probabilities, reaction energetics, and roto‐vibrational states of formed molecules. The results show the need for correct treatment of the multiphonon excitation mechanism in molecule–surface interactions.
Emilin genes are duplicated and dynamically expressed during zebrafish embryonic development
Authors: Milanetto Martina , Tiso Natascia , Braghetta Paola , Volpin Dino , Argenton Francesco , Bonaldo Paolo 
Published: December 2007

AbstractEmilins are a family of extracellular matrix proteins with common structural organization and containing a characteristic N‐terminal cysteine‐rich domain. The prototype of this family, Emilin‐1, is found in human and murine organs in association with elastic fibers, and other emilins were recently isolated in mammals. To gain insight into these proteins in lower vertebrates, we investigated the expression of emilins in the fish Danio rerio. Using sequence similarity tools, we identified eight members of this family in zebrafish. Each emilin gene has two paralogs in zebrafish, showing conserved structure with the human ortholog. In situ hybridization revealed that expression of zebrafish emilin genes is regulated in a spatiotemporal manner during embryonic development, with overlapping and site‐specific patterns mostly including mesenchymal structures. Expression of certain emilin genes in peculiar areas, such as the central nervous system or the posterior notochord, suggests that they may play a role in key morphogenetic processes.

Sexual dimorphic expression of DMRT1 and Sox9a during gonadal differentiation and hormone‐induced sex reversal in the teleost fish Nile tilapia (Oreochromis niloticus)
Authors: Kobayashi Tohru , Kajiura‐Kobayashi Hiroko , Guan Guijun , Nagahama Yoshitaka 
Published: December 2007

AbstractWe examined the expression profiles of tDMRT1 and Sox9a during gonadal sex differentiation and hormone‐induced sex reversal. tDMRT1 was detected in the gonial germ‐cell–surrounding cells in XY fry specifically before the appearance of any signs of morphological sex differentiation, that is, sex differences in germ cell number and histogenesis, such as differentiation into intratesticular efferent duct or ovarian cavity. The signals became localized in the Sertoli and epithelial cells comprising the efferent duct during gonadal differentiation. After the induction of XY sex reversal with estrogen, tDMRT1 decreased and then disappeared completely. In contrast, tDMRT1 was expressed in the germ‐cell–surrounding cells in XX sex reversal with androgen. On the other hand, Sox9a did not show sexual dimorphism before the appearance of sex differences in histogenesis and was not expressed in the efferent duct in the testis. These results suggest that tDMRT1 is a superior testicular differentiation marker in tilapia. Developmental Dynamics 237:297–306, 2008. © 2007 Wiley‐Liss, Inc.
Polysialyltransferase expression is linked to neuronal migration in the developing and adult zebrafish
Authors: Rieger Sandra , Volkmann Katrin , Köster Reinhard W. 
Published: December 2007

AbstractModulation of cell–cell adhesion is crucial for regulating neuronal migration and maintenance of structural plasticity in the embryonic and mature brain. Such modulation can be obtained by the enzymatic attachment of polysialic acid (PSA) to the neural cell adhesion molecule (NCAM) by means of the polysialyltransferases STX and PST. Thus, differential expression of STX and PST is likely to be responsible for varying functions of PSA‐NCAM during neuronal differentiation, maintenance, plasticity, and regeneration. We have isolated the zebrafish homologues of STX (St8sia2) and PST (St8sia4) and demonstrate that their expression in the embryonic and adult nervous system is often confined to regions of neuronal migration. Moreover, in the adult cerebellum, the complementary expression pattern of both polysialyltransferases suggests a function in regulating cerebellar neuronal plasticity. Enzymatic removal of PSA in the embryonic cerebellum results in impaired neuronal migration, suggesting that PSA‐NCAM is a key regulator of motility for cerebellar neuronal progenitors.

Legibility evaluation using point‐of‐regard measurement
Authors: Saito Daisuke , Saito Keiichi , Saito Masao 
Published: December 2007

AbstractWeb site visibility has become important because of the rapid dissemination of the World Wide Web, and combinations of foreground and background colors are crucial in providing high visibility. In our previous studies, the visibilities of several web‐safe color combinations were examined using a psychological method. In those studies, simple stimuli were used because of experimental restriction. In this paper, legibility of sentences on web sites was examined using a psychophysiological method, point‐of‐regard measurement, to obtain other practical data. Ten people with normal color sensations ranging from ages 21 to 29 were recruited. The number of characters per line in each page was arranged in the same number, and the four representative achromatic web‐safe colors, that is, #000000, #666666, #999999, and #CCCCCC, were examined. The reading time per character and the gaze time per line were obtained from point‐of‐regard measurement, and the normalized with the reading time and the gaze time of the three colors were calculated and compared. It was found that the time of reading and gaze become long at the same ratio when the contrast decreases by point‐of‐regard measurement. Therefore, it was indicated that the legibility of color combinations could be estimated by point‐of‐regard measurement. © 2007 Wiley Periodicals, Inc.

Observation of ULF geomagnetic variations and detection of ULF emissions associated with earthquakes: Review
Authors: Hayakawa Masashi , Hattori Katsumi , Ohta Kenji 
Published: December 2007

AbstractEarthquake‐related electromagnetic phenomena have recently been considered a promising candidate for short‐term earthquake prediction. There has accumulated a lot of evidence of precursory signatures in a wide frequency range (DC to VHF), but the ULF geomagnetic change is one of the most promising phenomena. We review our results on seismogenic ULF emissions; and characteristics of those emissions and methodologies to detect abnormal changes in ULF electromagnetic field associated with earthquakes. © 2007 Wiley Periodicals, Inc.
