Published: September 2014

The city of Iznik, called Nikaia or Nicaea in ancient times, is located in northwest Anatolia, Turkey. Nicaea is renowned especially for the first Council of Nicaea convened by the Roman emperor Constantine in ad 325 in an attempt to unify the Church. During an international field course on the geophysical exploration of archaeological targets we detected the remains of a small previously unknown Byzantine church on a fallow lot of land inside the city. The church is oriented parallel to the ancient Hippodamian street grid that deviates from the modern street system of the quarter by ~45°. We found the contours of the nave, two aisles and three apses as well as evidence of a partly refilled grave. The geophysical measurements indicate that the foundations of the church consist of low‐porosity hard rock with a low magnetic susceptibility, probably limestone or sandstone embedded in fluvial sediments. The field study is based on ground‐penetrating radar (GPR), magnetics, electric resistivity tomography (ERT) and microgravimetry. It highlights the strength and necessity of combining different geophysical methods in exploring and characterizing archaeological sites. In fact, the foundation walls of the church do not show any magnetic anomaly but could be delineated clearly only by GPR. The wall remains appear as highly resistive spots in ERT. By converting the three‐dimensional GPR image into an electric resistivity model we could verify that the ERT results fully correspond to the ruins found by GPR. The structure interpreted as a loosely refilled grave is indicated mainly by a weak gravity anomaly (~9 μGal) and a diffuse reflection pattern in GPR. Electric forward modelling shows that this structure leads to an additional increase of a high resistivity anomaly, which is primarily caused by foundation rocks, but it cannot be resolved within the ERT pattern a priori.

Published: September 2014

Comparative effectiveness of interventions for children with autism spectrum disorders (ASDs) that incorporates costs is lacking due to the scarcity of information on health utility scores or preference‐weighted outcomes typically used for calculating quality‐adjusted life years (QALYs). This study created algorithms for mapping clinical and behavioral measures for children withASDsto health utility scores. The algorithms could be useful for estimating the value of different interventions and treatments used in the care of children withASDs. Participants were recruited from twoAutismTreatmentNetwork sites. Health utility data based on the Health Utilities Index Mark 3 (HUI3) for the child were obtained from the primary caregiver (proxy‐reported) through a survey (N = 224). During the initial clinic visit, proxy‐reported measures of theChildBehaviorChecklist,VinelandII AdaptiveBehaviorScales, and the Pediatric Quality of Life Inventory 4.0 (start measures) were obtained and then merged with the survey data. Nine mapping algorithms were developed using theHUI3 scores as dependent variables in ordinary least squares regressions along with the start measures, theAutismDiagnosticObservationSchedule, to measure severity, child age, and cognitive ability as independent predictors. In‐sample cross‐validation was conducted to evaluate predictive accuracy. Multiple imputation techniques were used for missing data. The average age for children withASDsin this study was 8.4 (standard deviation = 3.5) years. Almost half of the children (47%) had cognitive impairment (IQ ≤ 70). Total scores for all of the outcome measures were significantly associated with the HUI3 score. The algorithms can be applied to clinical studies containing start measures of children withASDsto predictQALYsgained from interventions.Autism Res2014, 7: 649–663.© 2014 International Society for Autism Research, Wiley Periodicals, Inc.
Left‐Hemispheric Microstructural Abnormalities in Children With High‐Functioning Autism Spectrum Disorder
Authors: Peterson Daniel , Mahajan Rajneesh , Crocetti Deana , Mejia Amanda , Mostofsky Stewart
Published: September 2014

Current theories of the neurobiological basis of autism spectrum disorder (ASD) posit an altered pattern of connectivity in large‐scale brain networks. Here we used diffusion tensor imaging to investigate the microstructural properties of the white matter (WM) that mediates interregional connectivity in 36 high‐functioning children with ASD (HF‐ASD) as compared with 37 controls. By employing an atlas‐based analysis using large deformation diffeometric morphic mapping registration, a widespread but left‐lateralized pattern of abnormalities was revealed. The mean diffusivity (MD) of water in the WM of HF‐ASD children was significantly elevated throughout the left hemisphere, particularly in the outer‐zone cortical WM. Across diagnostic groups, there was a significant effect of age on left‐hemisphere MD, with a similar reduction in MD during childhood in both typically developing and HF‐ASD children. The increased MD in children with HF‐ASD suggests hypomyelination and may reflect increased short‐range cortico‐cortical connections subsequent to early WM overgrowth. These findings also highlight left‐hemispheric connectivity as relevant to the pathophysiology of ASD and indicate that the spatial distribution of microstructural abnormalities in HF‐ASD is widespread and left‐lateralized. This altered left‐hemispheric connectivity may contribute to deficits in communication and praxis observed in ASD.

Membrane transport mechanisms of choline in human intestinal epithelial LS180 cells
Authors: Horie Asuka , Ishida Kazuya , Watanabe Yuri , Shibata Kaito , Hashimoto Yukiya
Published: September 2014

The aim of the present study was to investigate the membrane transport mechanisms of choline using human intestinal epithelial LS180 cells. The mRNA of choline transporter‐like proteins (CTLs) was expressed significantly in LS180 cells, and the rank order was CTL1 > CTL4 > CTL3 > CTL2 > CTL5. In contrast, the mRNA expression of other choline transporters, organic cation transporter (OCT) 1, OCT2 and high‐affinity choline transporter 1 (CHT1), was considerably lower in LS180 cells. Five mm unlabelled choline, hemicolinium‐3 and guanidine, but not tetraethylammonium, inhibited the cellular uptake of 100 µm choline in LS180 cells. The uptake of choline into LS180 cells was virtually Na+‐independent. The uptake of choline was significantly decreased by acidification of the extracellular pH; however, it was not increased by alkalization of the extracellular pH. In addition, both acidification and alkalization of intracellular pH decreased the uptake of choline, indicating that the choline uptake in LS180 cells is not stimulated by the outward H+ gradient. On the other hand, the uptake of choline was decreased by membrane depolarization along with increasing extracellular K+ concentration. In addition, the Na+‐independent uptake of choline was saturable, and the Km value was estimated to be 108 µm. These findings suggest that the uptake of choline into LS180 cells is membrane potential‐dependent, but not outward H+ gradient‐dependent. Copyright © 2014 John Wiley & Sons, Ltd.
Effects of GSM‐modulated 900 MHz radiofrequency electromagnetic fields on the hematopoietic potential of mouse bone marrow cells

Published: September 2014

Studies describing the influence of radiofrequency electromagnetic fields on bone marrow cells (BMC) often lack functional data. We examined the effects of in vivo exposure to a Global System for Mobile Communications (GSM) modulated 900 MHz RF fields on BMC using two transplantation models. X‐irradiated syngeneic mice were injected with BMC from either RF‐field‐exposed, sham‐exposed or cage control mice. Twelve weeks after transplantation, no differences in thymocyte number, frequency of subpopulations and cell proliferation were found in mice receiving BMC from either group. Also, in the spleen cell number, percentages of B/T cells, B/T‐cell proliferation, and interferon γ (IFN‐γ) production were similar in all groups. In parallel, a mixture of BMC from congenic sham‐ and RF‐exposed mice were co‐transplanted into lymphopenic Rag2 deficient mice. BMC from RF‐exposed and sham‐exposed mice displayed no advantage or disadvantage when competing for the replenishment of lymphatic organs with mature lymphocytes in Rag2 deficient mice. This model revealed that BMC from sham‐exposed and RF‐exposed mice were less efficient than BMC from cage control mice in repopulating the thymus, an effect likely due to restraint stress. In conclusion, our results showed no effects of in vivo exposure to GSM‐modulated RF‐fields on the ability of bone marrow (BM) precursors to long‐term reconstitute peripheral T and B cell compartments.

Published: September 2014

A sucrose utilization pathway was established in Ralstonia eutropha NCIMB11599 and R. eutropha 437‐540 by introducing the Mannheimia succiniciproducens MBEL55E sacC gene that encodes β‐fructofuranosidase. These engineered strains were examined for the production of poly(3‐hydroxybutyrate) [P(3HB)] and poly(3‐hydroxybutyrate‐co‐lactate) [P(3HB‐co‐LA)], respectively, from sucrose as a carbon source. It was found that β‐fructofuranosidase excreted into the culture medium could hydrolyze sucrose to glucose and fructose, which were efficiently used as carbon sources by recombinant R. eutropha strains. When R. eutropha NCIMB11599 expressing the sacC gene was cultured in nitrogen‐free chemically defined medium containing 20 g/L of sucrose, a high P(3HB) content of 73.2 wt% could be obtained. In addition, R. eutropha 437‐540 expressing the Pseudomonas sp. MBEL 6‐19 phaC1437 gene and the Clostridium propionicum pct540 gene accumulated P(3HB‐co‐21.5 mol% LA) to a polymer content of 19.5 wt% from sucrose by the expression of the sacC gene and the Escherichia coli ldhA gene. The molecular weights of P(3HB) and P(3HB‐co‐21.5 mol%LA) synthesized in R. eutropha using sucrose as a carbon source were 3.52 × 105 (Mn) and 2.19 × 104 (Mn), respectively. The engineered R. eutropha strains reported here will be useful for the production of polyhydroxyalkanoates (PHAs) from sucrose, one of the most abundant and relatively inexpensive carbon sources.
