Sedimentary feature on Borsog Bay, eastern shore of Lake Khuvsgul in Northern Mongolia
This study reports on the sedimentary characteristics of Lake Khuvsgul which is located at the southern end of the Baikal Rift System within the continental interior of East Eurasia. With an elevation of 1645 m a.s.l., it has a climate that is mainly controlled by the Siberian-Mongolian high pressure system and the westerly wind systems from the Atlantic Ocean. Lake Khuvsgul, Mongolia's second largest lake by surface area (2760 km2), is the country's deepest fresh water lake with a bottom that is only 262 m a.s.l. Fed by 96 rivers and streams, it is drained by the Eg River which, after joining the Selenge River, flows into Lake Baikal. Analysis of a 12.3 m core from Borsog Bay near the eastern shore of the lake indicates a sedimentation rate of about 0.08 cm/a. It is believed that this relatively high sedimentation rate is due to the large sedimentary input from River Borsog and the variability of the turbidity currents at depths shallower than 9 m. It further suggests that the large sedimentation rate may be correlated with the annual and seasonal variations in the dominant westerly wind system over the Siberian Plateau. Such variations have resulted in a lowering of lake level and impacted the rate of erosion within the river's catchment area and therefore the sediment input to the lake. Because this is a preliminary report, further research into the sedimentary dynamics within Lake Khuvsgul and the role played in those dynamics by the climatic variability over Mongolia and Central Asia is planned.

The use of the 210Pb method for preliminary evaluating the sedimentation rate in Amazon river mouth
This investigation reports the preliminary results for determining the sedimentation rate at the Amazonas River mouth, Brazil, by the 210Pb method. The CIC (constant initial concentration) of unsupported/excess 210Pb model was successfully applied to one sediments core. The measurements were made in a sediments core comprising ten samples 10 cm - thick each. The year of the sampling (2006) was used as reference for the establishment of the rate of sedimentation from the beginning of the top of the testimony. However, the atmospheric conditions and climate in Amapá State, Brazil, claimed for optimization of the results. Because the Channel North is opened into the Atlantic Ocean, it exhibits a huge water volume, causing a permanent motion of sediments and water. So, heavy waves are formed at the water surface, stirring the upper sand strata. Only at a depth of 40-50 cm the profile tends to be more homogeneous, where it is mostly composed by fine sand and very fine sand. Thus, it is reasonable utilize the CIC model from 210Pb data, which allows estimate a sedimentation rate corresponding to 0.61 g/cm2yr and a mean linear rate of 0.8 cm/yr. The 238U and 210Pb activities in the sediments allowed the reconstruction of the sedimentation processes over a period of about 130 years.
An integrated geophysical study of the western part of the Rochechouart‐Chassenon impact structure, Charente, France

Published: July 2010

ABSTRACTA multi‐method geophysical survey was carried out with the aim of reassessing the structure of the Rochechouart‐Chassenon astrobleme and the geometry of the impact‐related formations, referred to as fallout breccias, in the vicinity of Chassenon. Gravity data extracted from the BRGM InfoTerre database were reprocessed and revealed both the shape of the astrobleme and the presence of a small negative gravity anomaly close to Chassenon, due to the low density of impact‐related rocks; a 2D gravity model across the fallout deposits was provided. Geological settings, well‐logging and geophysical soundings (direct current (DC), time‐domain electromagnetic (TDEM) and frequency‐domain electromagnetic (FDEM)) were carried out on the fallout breccias at Chassenon. The 1D resistivity models based on TDEM and DC soundings, resulting from a mutually constrained inversion and coupled with 1D models of FDEM data, were constrained by borehole data and provided 2D resistivity models across the fallout deposits of Chassenon. The combination of these methods allows the description of both the impact‐related rocks geometry and the global structure of fallout breccia remains at Chassenon. The study also shows that the fallout breccia has a complex structure, consisting of thin layers of lithic breccia and suevite, the total thickness of which is larger at Chassenon than previously estimated by means of geological analysis.
Correction of the attenuation effect of vegetation on airborne gamma‐ray spectrometry data using laser altimeter data
Authors: Ahl Andreas , Bieber Gerhard 
Published: July 2010

ABSTRACTThe interpretation of airborne gamma‐ray data is considerably complicated by the attenuating effects of vegetation. In order to correct these effects we used simultaneously measured laser altimeter data to characterize the vegetation cover. To describe the attenuation effect and correct its consequences on gamma‐ray data we used a simple model of exponential absorption of monoenergetic gamma‐ray photons by an attenuating medium. The determination of the corresponding linear attenuation coefficients for potassium (K), uranium (U) and thorium (Th) is based on data from an airborne geophysical survey in Austria.
Geophysical modelling of the Ebersbrunn diatreme, western Saxony, Germany
Authors: Matthes Heidrun , Kroner Corinna , Jahr Thomas , Kämpf Horst 
Published: July 2010

ABSTRACTThe Ebersbrunn diatreme near Ebersbrunn, western Saxony, Germany, causes an elliptical Bouguer anomaly of about –2.5 m Gal, which covers an area of approximately 2.2 km × 2 km and an elliptical magnetic anomaly with values between –250 nT and 1000 nT about half a kilometre smaller in diameter and situated within the southern part of the Bouguer anomaly. Considering magnetic susceptibility and density values determined from core samples of the diatreme, a symmetrical, cone‐shaped body with an oval surface outcrop of 2 km × 1.5 km and a dip angle of the slopes of about 82° is modelled. It comprises a central structure with a diameter of 800–900 m and susceptibility values up to 9000*10−6 SI higher and densities up to 220 kg/m3 lower than the surrounding chimney. Additionally, susceptibility within the body increases with depth and decreases with the degree of weathering. The geometry can clearly be associated with the diatreme of a maar‐diatreme‐volcano. Regarding the petrographic information (the occurrence of pelletal lapilli as juvenile phase, the basaltoid character of the occurring ground mass of magmatic origin and 80% wall rock content) and the final geophysical model, the Ebersbrunn structure can definitely be regarded as the partially eroded remnant (diatreme and root zone) of a maar‐diatreme‐volcano. The association of earthquake swarms in intraplate regions of intersecting fractures and volcanism has led to renewed interest in the eroded maar‐diatreme‐volcano.
Imaging a shallow aquitard with seismic reflection data in Memphis, Tennessee, USA. Part I: source comparison, walk‐away tests and the plus‐minus method
Authors: Ge Jiandang , Beatrice Magnani Maria , Waldron Brian 
Published: July 2010

ABSTRACTTwo walk‐away tests were conducted at two sites in Memphis, Tennessee, USA. One site is representative of an urban setting (road median) while the other represents a rural setting (metropolitan park). Three P‐wave sources, a 7.5 kg sledgehammer, a 20 kg weight‐drop and a 12‐gauge shotgun, were tested. Analysis of the data collected indicates that the seismic data recorded from the shotgun source possess the strongest energy, the highest dominant frequency, the broadest frequency band and the least amount of ground roll energy. The source repeatability was also studied by observing the first cycle of each seismic source, showing that the shotgun can generate the most repeatable source wavelets. None of the data recorded from the three sources show significant seismic energy above 100 Hz due to seismic wave attenuation. The loess in the rural site exacerbated the attenuation and resulted in a much lower peak frequency (43.7 Hz), which is nearly half of the peak frequency recorded at the urban site (85.3 Hz). Since attenuation can be a big factor in shallow reflection surveying, we recommend that site attenuation be considered before a reflection survey is performed in the Memphis area and a reflection survey be conducted outside of the loess blanketed area when possible. Since the final goal of the survey is to search for aquitard breaches, Hagedoorns’ plus‐minus method was applied to the walk‐away data set to map the first refractor, the top of the aquitard. One depression from the obtained structure was interpreted as a paleochannel, indicating that river channel erosion may be one of the causes for the formation of aquitard breaches.
Imaging a shallow aquitard with seismic reflection data in Memphis, Tennessee, USA. Part II: data analysis, interpretation and traveltime tomography

Published: July 2010

ABSTRACTWe collected P‐wave seismic reflection data to image suspected breaches in the confining unit (aquitard) above the Memphis aquifer in Memphis, Tennessee, USA, where previous studies of water quality have suggested potential contamination. A 1‐km‐long reflection line was acquired across depressions of the water table that have been interpreted to reflect a breach in the aquitard. Although raw data are dominated by surface waves, after frequency filtering, shot static correction and filtering, consistent reflections can be observed. Integration of constant velocity analysis (CVS) and super gather semblance analysis was used to determine the RMS velocity field. The stack section shows a set of shallow reflectors interpreted to correspond to the top and bottom of the confining unit. The aquitard thins by about half from the north end to the south end along the reflection line. The continuity of the top and bottom of the aquitard was disrupted by a few faults interpreted along the line. None of these faults juxtapose the surficial aquifer against the Memphis aquifer but it is possible that the faults themselves may act as a hydraulic connection between the surficial aquifer and the Memphis aquifer and thus serve as pathways for a potential leakage. The refraction tomography technique was applied to the first arrival data and it revealed three depressions that are interpreted as paleochannels on the upper part of the confining unit, which is consistent with the background geology of the area. These inferred paleochannels may suggest that ancient river channel erosion may contribute to the process responsible for the formation of aquitard breaches in this area.

AbstractWithin the European food market, traditional food products (TFP) represent a growing segment. Nonetheless, European consumers' definition and perception of TFP have not been thoroughly addressed thus far. The specific aim of this study was to provide an all‐embracing consumer definition of the concept of TFP that is comfortable for the largest possible majority of European food consumers. Cross‐sectional survey data were collected from representative consumer samples from Belgium, France, Italy, Norway, Poland, and Spain in November 2007, yielding a total sample of 4,828 participants. The study elaborates on country‐specific peculiarities and identifies consumer segments that differ in the emphasis they place in the conceptualization of TFP. The following definition emerged, A traditional food product is a product frequently consumed or associated to specific celebrations and/or seasons, transmitted from one generation to another, made in a specific way according to gastronomic heritage, naturally processed, and distinguished and known because of its sensory properties and associated to a certain local area, region or country. Cross‐European homogeneity was found in the elements to include in the definition, across and within‐country heterogeneity existed regarding the specific emphasis of particular elements. Four consumer segments were distinguished by whom TFP are predominantly defined as multiconcept, usual/familiar, authentic/typical, and inherited. The first segment displayed a very broad conceptualization, without a clear differentiation. For the latter three segments, particular elements dominated their conceptualization. Product positioning, marketing, and communication challenges for TFP facing these consumer segments are discussed. [EconLit citations: D12; M39; Q13]. © 2010 Wiley Periodicals, Inc.

AbstractBackgroundPolice responders to the 2001 World Trade Center (WTC) disaster were previously reported to have an increased prevalence of probable posttraumatic stress disorder (PTSD).MethodsFour thousand seventeen police responders (3,435 men and 582 women) were interviewed 2–3 years after 9/11/01 as part of the World Trade Center Health Registry. Demographic, occupational, and event‐specific risk factors were evaluated for probable PTSD, determined by DSM‐IV criteria using the Posttraumatic Stress Checklist (PCL).ResultsOverall prevalence of probable PTSD was 8.3% (women: 13.9%; men: 7.4%, P < 0.001). Risk factors for both genders included 9/11‐related injury and older age. For men, specific risk factors were: presence in WTC Towers on 9/11 and Hispanic ethnicity; and for women, witnessing horror and education less than a college degree.ConclusionsSignificantly higher prevalence of probable PTSD was found for female police responders. Although consistent with civilian populations, this finding contrasts with other studies of PTSD and WTC rescue and recovery workers, and police prior to 9/11. Am. J. Ind.

Hedgehog signaling update
Authors: Cohen Jr. M. Michael 
Published: July 2010

AbstractIn vertebrate hedgehog signaling, hedgehog ligands are processed to become bilipidated and then multimerize, which allows them to leave the signaling cell via Dispatched 1 and become transported via glypicans and megalin to the responding cells. Hedgehog then interacts with a complex of Patched 1 and Cdo/Boc, which activates endocytic Smoothened to the cilium. Patched 1 regulates the activity of Smoothened (1) via Vitamin D3, which inhibits Smoothened in the absence of hedgehog ligand or (2) via oxysterols, which activate Smoothened in the presence of hedgehog ligand. Hedgehog ligands also interact with Hip1, Patched 2, and Gas1, which regulate the range as well as the level of hedgehog signaling. In vertebrates, Smoothened is shortened at its C‐terminal end and lacks most of the phosphorylation sites of importance inDrosophila. Cos2, also of importance inDrosophila, plays no role in mammalian transduction, nor do its homologs Kif7 and Kif27. The cilium may provide a function analogous to that of Cos2 by linking Smoothened to the modulation of Gli transcription factors. Disorders associated with the hedgehog signaling network follow, including nevoid basal cell carcinoma syndrome, holoprosencephaly, Smith–Lemli–Opitz syndrome, Greig cephalopolysyndactyly syndrome, Pallister–Hall syndrome, Carpenter syndrome, and Rubinstein–Taybi syndrome. © 2010 Wiley‐Liss, Inc.
Palmoplantar keratoderma, pseudo‐ainhum, and universal atrichia: A new patient and review of the palmoplantar keratoderma‐congenital alopecia syndrome

Published: July 2010

AbstractPalmoplantar keratoderma (PPK) may concur with congenital alopecia (CA) in various genodermatoses. We report on a 10‐year‐old girl with generalized atrichia and a severe form of PPK causing pseudo‐ainhum, sclerodactyly, and contractures, a phenotype not consistent with any well‐defined condition. Non‐specific additional findings comprised mild nail dystrophy and widespread keratosis pilaris including ulerythema ophryogenes. Direct sequencing of the GJB2 and LOR coding regions yielded normal results. A review identified two additional sporadic and four familial cases with PPK and CA. Comparison between familial cases suggested the existence of two genetically and phenotypically distinct types of PPK‐CA: (i) an autosomal dominant form (Stevanović type), a variable and benign phenotype without significant hand complications, and (ii) a more complex autosomal recessive variant (Wallis type) with contractures, sclerodactyly, and pseudo‐ainhum. Nuclear cataract may represent an additional although not constant finding in the Wallis type PPK‐CA. Further reports are required to test this preliminary conclusion. © 2010 Wiley‐Liss, Inc.
Living with Gaucher disease: Emotional health, psychosocial needs and concerns of individuals with Gaucher disease

Published: July 2010

AbstractGaucher disease (GD) is the most common hereditary lysosomal storage disorder. Of the three variants of GD, type 1 accounts for 90% of cases. Patients with GD suffer from multiple medical symptoms and conditions. Clinical features of type 1 GD include hepatosplenomegaly; hematologic complications such as anemia and thrombocytopenia; and skeletal disease leading to avascular necrosis, osteopenia, and osteosclerosis. GD has unique features as a chronic illness: the disorder often presents with mild symptoms, and is frequently diagnosed in later childhood or adulthood. The treatment, enzyme replacement therapy (ERT), is efficacious. However, that same effective treatment is intrusive, expensive, and requires that patients restructure their work and personal schedules. Since the age of presentation can be anywhere between infancy and the eighth decade, the diagnostic process can be prolonged and stressful. The success of ERT notwithstanding, GD patients show distinct psychological complications [Packman et al. (2006); J Inherit Metab Dis 29:99–105]. In the present study, we describe the concerns, needs, challenges and positive effects of GD from the patients' perspective using in depth interviews of 28 individual affected by GD. Five core themes emerge: (1) difficulty coping with the diagnosis; (2) impact of pain on work, career, and recreational activities; (3) insurance concerns; (4) psychological distress (e.g., mood changes and anxiety); and (5) positive effects—strengthened family and social relationships and positive outlook. Our results highlight and expand awareness of the psychological and social needs of GD patients. This study calls for a collaborative, multidisciplinary effort in treating these patients and their families. © 2010 Wiley‐Liss, Inc.
Parent‐of‐origin effects for MSX1 in a Chilean population with nonsyndromic cleft lip/palate
Authors: Suazo José , Santos José Luis , Jara Lilian , Blanco Rafael 
Published: July 2010

AbstractBased on association and sequencing studies, investigators have postulated muscle segment homeobox 1 (MSX1) as a strong candidate gene involved in the causation of nonsyndromic cleft lip with or without cleft palate (NSCLP). Parent‐of‐origin effects have been suggested for some NSCLP candidate genes but not for MSX1. The aims of the present study were to test for allele/haplotype associations applying the transmission disequilibrium test (TDT) and the transmission asymmetry test (TAT) to evaluate the possible parent‐of‐origin effects of MSX1 in Chilean patients with NSCLP. We analyzed five SNPs (rs6446693/c.‐425G>T/c.‐35G>A/rs3775261/rs12532) located from 6.3 kb upstream to 3′ UTR in a sample of 150 unrelated NSCLP case–parent trios. Four haplotypes showed overtransmission from parents to affected progeny, but individual SNPs did not. Two haplotypes presented allele combination C‐G‐A‐G (P = 0.035) and two T‐G‐C‐A (P = 0.044) (SNP order rs6446693/c.‐35G>A/rs3775261/rs12532). The rs12532 A allele had a 2.08‐fold increase in the risk of NSCLP when inherited from the father (95% CI: 1.10–4.02; P = 0.025), but not from the mother. These results could indicate epigenetic control by imprinting in the role of MSX1 in NSCLP. Different authors have proposed that some genes that play a role in NSCLP depend on parental origin. Our findings and those previously reported by our group show that a variety of factors appears to be involved in the association between MSX1 and NSCLP. The full mechanism of MSX1 in the development of NSCLP has not been fully understood. © 2010 Wiley‐Liss, Inc.
Femoral–facial syndrome: Prenatal diagnosis and clinical features. Report of three cases

Published: July 2010

AbstractThe objective of our article is to illustrate the earliest prenatal sonographic diagnosis of femoral–facial syndrome (FFS) and to illustrate the spectrum of clinical manifestations of this condition. We present serial sonographic evaluation with 3D evaluation in two fetuses diagnosed prenatally with FFS and the postnatal findings in three patients (one fetus following pregnancy interruption and two newborns one of whom was diagnosed prenatally) with FFS. The two patients with prenatally diagnosed FFS were found to have femoral shortening and characteristic facial features, one 12 weeks of gestation, and one at 15 weeks of gestation. The sonographic findings in the two prenatally diagnosed patients were confirmed after delivery. We also present a third patient who was diagnosed at delivery in whom the diagnosis was missed at a routine prenatal sonogram at 19 weeks of gestation. The patients reported herein expand the clinical spectrum of FFS. The utility of sonographic evaluation in diagnosis of the facial appearance and of the bony abnormalities in this condition is emphasized. © 2010 Wiley‐Liss, Inc.

Published: July 2010

AbstractA patient with atypical phenotypes of Prader–Willi syndrome (PWS) was subjected to investigate genomic copy numbers by microarray‐based comparative genomic hybridization analysis. Severe developmental delay, relative macrocephaly, protruding forehead, cardiac anomalies, and hydronephrosis were atypical for PWS. Concurrent deletions of 15q11‐13 and 5q35 regions were revealed and identified as paternally derived. The sizes and locations of the two deletions were typical for both deletions. Although each deletion independently contributed to the clinical features, developmental disturbance was very severe, suggesting combined effects. This is the first report of co‐occurrence of PWS and STS. The co‐occurrence of two syndromes is likely incidental. © 2010 Wiley‐Liss, Inc.
