Vegetation as a major conductor of geomorphic changes on the Earth surface: toward evolutionary geomorphology
Authors: Corenblit Dov , Steiger Johannes 
Published: February 2009

AbstractEarth surface processes and landforms may have coadjusted† with plant morphology, biomechanics and life‐history. We suggest that the colonization of land by plants at the early Silurian, and their propagation inside continents, represent critical phases of the coupling between geomorphic and biological processes on the Earth at a global scale. The consideration of this coupling involving geomorphic‐biological feedback mechanisms at the scales of ecological succession and organisms' evolution may promote the emergence of an evolutionary† geomorphology.

Fluvial hydraulics of hyperconcentrated floods in Chinese rivers
Authors: Wang Zhao‐Yin , Qi Pu , Melching Charles Steven 
Published: February 2009

AbstractHyperconcentrated floods, with sediment concentrations higher than 200 kg/m3, occur frequently in the Yellow River and its tributaries on the Loess Plateau. This paper studies the fluvial hydraulics of hyperconcentrated floods by statistical analysis and comparison with low sediment concentration floods. The fluvial process induced by hyperconcentrated floods is extremely rapid. The river morphology may be altered more at a faster rate by one hyperconcentrated flood than by low sediment concentration floods over a decade. The vertical sediment concentration distribution in hyperconcentrated floods is homogeneous. The Darcy–Weisbach coefficient of hyperconcentrated floods varies with the Reynolds number in the same way as normal open channel flows but a representative viscosity $h\ +\ {{2R} \over {3U}}\tau _B$ is used to replace the viscosity, η. If the concentration is not extremely high and the Reynolds number is larger than 2000, the flow is turbulent and the Darcy–Weisbach coefficient for the hyperconcentrated floods is almost the same as low sediment concentration floods. Serious channel erosion, which is referred to as ‘ripping up the bottom’ in Chinese, occurs in narrow‐deep channels during hyperconcentrated floods. However, in wide‐shallow channels, hyperconcentrated floods may result in serious sedimentation. Moreover, a hyperconcentrated flood may cause the channel to become narrower and deeper, thus, reducing the flood stage by more than 1 m if the flood event lasts longer than one day. The fluvial process during hyperconcentrated floods also changes the propagation of flood waves. Successive waves may catch up with and overlap the first wave, thus, increasing the peak discharge of the flood wave during flood propagation along the river course.

Published: February 2009

AbstractA wet atomising system has been employed as a novel method to prepare ultrafine Gd‐doped CeO2 (GDC) electrolyte slurries. By changing the fluid flow pressure and repeating the atomisation process several times for the same atomised slurries, we have obtained optimised ultrafine GDC slurry with high‐dispersed and homogeneous distribution. The sizes of the particles of GDC were in the range of tens of nanometres. A highly dense electrolyte layer (membrane) was prepared using the ultrafine GDC slurries for intermediate temperatures microtubular solid oxide fuel cell (SOFC) applications. The SOFC was fabricated by using supporting porous anode tubes of NiO and GDC, and the cathode consisted of La0.6Sr0.4Co0.2Fe0.8O3–y and GDC. A dense 10 μm GDC electrolyte layer was obtained at a lower sintering temperature of 1,250 °C for 1 h. The SOFC was tested with humidified (3% H2O) hydrogen as a fuel and the static air as an oxidant, and the tubular cell maintained its high performance even at 500 °C.
On the equivalence of executed and imagined movements: Evidence from lateralized motor and nonmotor potentials
Authors: Kranczioch Cornelia , Mathews Simon , Dean Phil J.A. , Sterr Annette 
Published: February 2009

AbstractThe neural simulation theory assumes that motor imagery and motor execution draw on a shared set of mechanisms underlying motor cognition. Evidence is accumulating that motor imagery and motor execution have many common features. The extent of the similarity and whether it spreads into the preparation phase is however unclear. This study used electroencephalographic recordings to compare the effects of providing advance information about upcoming movements on preparatory processing in a motor imagery and execution paradigm. Event‐related potential data were recorded in a priming task where participants were cued to perform simple or complex finger movements. We hypothesized that a high degree of functional similarity of motor imagery and motor execution should be reflected in similar alterations of lateralized preparatory activity. Lateralized preparatory activity was indeed very similar, showing both motor‐related (lateralized readiness potential, LRP) and cognitive components (anterior directing‐attention negativity or ADAN, late directing‐attention positivity or LDAP). Dipole analysis revealed that LRP, ADAN, and LDAP sources were very comparable for motor imagination and execution. Results generally support the idea of common underlying functional networks subserving both the preparation for execution and imagery of movements. They also provide a broader context for this notion by revealing similarities in cognitive components associated with the movement tasks. Hum Brain Mapp, 2009. © 2009 Wiley‐Liss, Inc.
An instrumental variables evaluation of the effect of antidepressant use on employment among HIV‐infected women using antiretroviral therapy in the United States: 1996–2004
Authors: Galárraga Omar , Salkever David S. , Cook Judith A. , Gange Stephen J. 
Published: February 2009

AbstractDepression is a common condition among patients with HIV. This paper uses panel data for 1234 participants from the Women's Interagency HIV Study to estimate the effect of antidepressant use on the likelihood of being employed among women receiving highly active antiretroviral therapy (HAART) in the United States from 1996 to 2004. We show that naive regressions of antidepressant use on employment generally result in negative or non‐significant coefficients, whereas the instrumental variables (IVs) approach shows a positive and significant effect of antidepressant use on the employment probability of women living with HIV. We use IVs to predict antidepressant use independently of outcomes, thus addressing potential biases (e.g. more depressed women are more likely to receive antidepressant treatment, but they are also more likely to be unemployed). The results are consistent for linear (random and fixed effects) as well as non‐linear (bivariate probit) specifications. Among women receiving HAART, and controlling for individual and local area labor market characteristics, the use of antidepressants is associated with a 29‐percentage‐point higher probability of being employed. Improved efforts to test, diagnose and treat depression among HIV‐positive patients may improve not only clinical indicators but also labor market outcomes. Copyright © 2009 John Wiley & Sons, Ltd.
Measuring consumer perception of product creativity: Impact on satisfaction and purchasability
Authors: Horn Diana , Salvendy Gavriel 
Published: February 2009

AbstractIn the current value‐based economy, product creativity is a potential resource for organizations to compete, thus emphasizing the need for product creativity measurement. Two studies were performed to refine and validate a previously tested model and measurement of consumer perception of product creativity: one with web‐based evaluations (N = 208) of chairs and lamps and one with paper‐based evaluations (N = 105) of individually selected products. Results of exploratory factor analyses indicated three main product creativity factors: Affect, Importance, and Novelty, which explained 72% of the common variance. Results of stepwise regressions indicated that the Affect factor significantly predicts (65% of the explained variance) willingness to purchase creative consumer products. One major contribution of this research is the finding that affect is as equally (R2 = .28) important as novelty (R2 = .25) in consumer perception of product creativity. Theoretical and practical implications are discussed for the Affect, Importance, and Novelty product creativity factors, and general creativity guidelines are provided for consumer product design. © 2009 Wiley Periodicals, Inc.
Exploring time‐dependent symptom outcomes in office staff
Authors: Lu Xiaoshu , Toivonen Risto , Takala Esa‐Pekka 
Published: February 2009

AbstractThis article illustrates the application of a new mathematical model developed for the study of time‐dependent health outcomes for office staff during computer work. The model describes the time‐dependent associations of computer usage with outcomes expressed as discomfort in multiple body regions. The association is explicitly presented with a functional relationship that is parameterized by body regions. The validation of the model demonstrated accuracy in reproducing the observed quantities for the study population. Therefore, we used this model to assess the impact of computer‐related work exposure on discomfort in different body regions among office staff to better understand the behavior of musculoskeletal and other symptoms. The exposures and outcomes were recorded parallel in time as usage of keyboard and mouse and with diaries of discomfort. The body regions of neck/shoulders, eyes, head, shoulder joint/upper arm, and upper back were identified to have the highest discomfort levels and rates for the development of discomfort parallel with exposures. Most of our findings are consistent with the literature. The developed mathematical methodology may be used to understand how the human body reacts to computer work to further prevent potential musculoskeletal and other disorders. © 2009 Wiley Periodicals, Inc.
An electromyographic investigation of asymmetric lifting and moving of a load: I. Effects of load lift from floor to target shelves
Authors: Das Biman , Mabaleka Godfrey 
Published: February 2009

AbstractThe range of normalized electromyography (EMG) values when lifting and moving a 5.84 kg box was between 0.12 and 0.77. The right iliocostalis and the right and the left external obliques showed significant increases in muscle activity at 90° of asymmetry. The average percentage increase for the stated muscles was 62.3% when compared to muscle activity at 0°. The left external oblique also responded significantly at 60° of asymmetry when compared to 0°. The knuckle, sternum, and reach heights significantly affected the left iliocostalis and the left and right erector spinae muscles. The average percentage increases in the stated muscles were 74.4% at knuckle height, 126.1% at sternum height, and 143.3% at reach height, when compared to floor level. Significant increases in muscle activity for the right iliocostalis and the right external oblique were registered only at the sternum and at the reach heights. For manual materials handling (MMH), an endeavor should be made to avoid asymmetric lifting and moving at 90° and from the floor level and to the reach height. To minimize the risk of back injury, the MMH task should be performed preferably within an asymmetry of 30° but not exceeding 60° asymmetry. © 2009 Wiley Periodicals, Inc.
Galantamine enhancement of long‐term potentiation is mediated by calcium/calmodulin‐dependent protein kinase II and protein kinase C activation

Published: February 2009

AbstractGalantamine, a novel Alzheimer's drug, is known to inhibit acetylcholinesterase activity and potentiate nicotinic acetylcholine receptor (nAChR) in the brain. We previously reported that galantamine potentiates the NMDA‐induced currents in primary cultured rat cortical neurons. We now studied the effects of galantamine on long‐term potentiation (LTP) in the rat hippocampal CA1 regions. The field excitatory postsynaptic potentials (fEPSPs) were induced by stimulation of the Schaffer collateral/commissural pathways in the hippocampal CA1 region. Treatment with 0.01–10 μM galantamine did not affect the slope of fEPSPs in the CA1 region. Galantamine treatment increased calcium/calmodulin‐dependent protein kinase II (CaMKII) and protein kinase Cα (PKCα) activities with a bell‐shaped dose–response curve peaked at 1 μM, thereby increasing the phosphorylation of AMPA receptor, myristoylated alanine‐rich protein kinase C, and NMDA receptor as downstream substrates of CaMKII and/or PKCα. By contrast, galatamine treatment did not affect protein kinase A activity. Consistent with the bell‐shaped CaMKII and PKCα activation, galantamine treatment enhanced LTP in the hippocampal CA1 regions with the same bell‐shaped dose–response curve. Furthermore, LTP potentiation induced by galantamine treatment at 1 μM was closely associated with both CaMKII and PKC activation with concomitant increase in phosphorylation of their downstream substrates except for synapsin I. In addition, the enhancement of LTP by galantamine was accompanied with α7‐type nAChR activation. These results suggest that galantamine potentiates NMDA receptor‐dependent LTP through α7‐type nAChR activation, by which the postsynaptic CaMKII and PKC are activated. © 2009 Wiley‐Liss, Inc.

AbstractIncreases in risk of breast cancer in successive generations of migrants to the United States from China and rapid temporal changes in incidence rates in China following social and economic changes clearly implicate environmental factors in the etiology of this disease. Case–control and cohort studies have provided evidence that at least some of these factors may be dietary. Iron, an essential element necessary for cell function, has also been demonstrated to have potential carcinogenic and co‐carcinogenic activities. Iron overload, which was previously uncommon, has become more common in the United States than iron deficiency and may be increasing in China concurrently with dramatic increases in meat consumption. A case–control study nested in a cohort of women in Shanghai, China, was conducted to evaluate possible associations between risk of proliferative and nonproliferative fibrocystic changes as well as breast cancer and dietary iron intake and plasma ferritin levels. Plasma ferritin levels and reported dietary iron intake were compared in 346 women with fibrocystic changes, 248 breast cancer cases and 1,040 controls. Increasing ferritin levels were significantly associated with increasing risk of nonproliferative fibrocystic changes (OR: 2.51, 95% CI: 1.16–5.45,ptrend = 0.04). Similar, but weaker, trends were observed for proliferative changes and for breast cancer. Risk of breast cancer relative to the risk of fibrocystic changes was associated with dietary iron intake in women with nonproliferative fibrocystic changes (OR: 2.63, 95% CI: 1.04–6.68,p= 0.02). In conclusion, this study finds significant associations between iron (stored and dietary) and fibrocystic disease and breast cancer. © 2009 UICC

Published: February 2009

AbstractTissue inhibitors of metalloproteinases (TIMPs) are endogenous inhibitors of matrix metalloproteinases which are involved in normal cellular processes and also in cancer development and progression. The purpose of this study was to evaluate polymorphisms in theTIMP‐2andTIMP‐3genes for their associations with breast cancer susceptibility and survival. Using data from the Shanghai Breast Cancer Study, 19 SNPs for each gene were evaluated for associations with breast cancer risk among 1,062 cases and 1,069 controls; associations with disease‐free and overall survival were evaluated among the cases. ForTIMP‐2, women with thers7501477TT genotype were 3 times more likely to be breast cancer cases than women with the CC genotype (OR: 2.9, 95% CI: 1.2–7.0). ForTIMP‐3, women with thers9609643AA genotype were 60% less likely to be breast cancer cases than women with the GG genotype (OR: 0.4, 95% CI: 0.2–1.0), whereas women with thers8136803TT genotype were 5 times more likely to be cases than women with the GG genotype (OR: 5.1, 95% CI: 1.1–24.3). Further, breast cancer cases withrs8136803TT were almost 4 times more likely to have decreased disease‐free survival (HR: 3.9, 95% CI: 1.4–10.6) and had a trend toward decreased overall survival (HR: 1.9, 95% CI: 0.6–6.1). An important study limitation was that these 3 SNPs (rs7501477, rs9609643, rs8136803) had low minor allele frequencies which resulted in small numbers of homozygote individuals. Genetic variation in theTIMP‐2andTIMP‐3genes may contribute to individual differences in breast cancer susceptibility and survival. © 2009 UICC

The effects of adult attachment and life stress on daily depression: a sample of Japanese university students
Authors: Liu Qingbo , Nagata Toshiaki , Shono Masahiro , Kitamura Toshinori 
Published: February 2009

AbstractTo investigate the relationship among adult attachment style, life stress, and daily depression, a sample of 437 undergraduate students was prospectively studied. Insecure adult attachment and perceived life stress were related to their daily depressive mood. Further analyses using both multiple hierarchical regression and structural equation models (SEM) demonstrated that adult attachment style and perceived life stress independently predicted depression and had no interactive effects on daily depression. The impact of adult attachment on depression was not contingent upon the presence of life stress and securely attached participants were less impacted by depression than insecurely attached ones. These results suggest that adult attachment can play an important role in mental health intervention and may be helpful when it comes to preventing and treating depression. © 2009 Wiley Periodicals, Inc.

Published: February 2009

AbstractSplenogonadal fusion limb defect syndrome (SGFLD) is a very rare abnormality. We report on a case with prenatal sonographic findings of a fetus with postnatally diagnosed SGFLD syndrome. This is also the second case of prenatal ultrasonographic diagnosis of gastrointestinal malrotation associated with SGFLD. A 26‐year‐old primigravid woman was referred to our clinic because of nonvisualization of both fetal femoral bones at 20 weeks of gestation. A detailed sonographic examination showed complete bilateral absence of lower limbs, micrognathia, single umbilical artery and a right‐sided stomach. Autopsy confirmed prenatal sonographic findings and additionally showed that the spleen was abnormally connected to the left gonad by a fibrous band. In conclusion, although all limbs and both sides were equally affected in most of the reported cases, SGFLD syndrome should be considered in cases with terminal limb defects of lower limbs. © 2009 Wiley Periodicals, Inc.

Published: February 2009

AbstractPurposeTo assess the added value of 3‐dimensional (3D) echocardiography with spatiotemporal image correlation (STIC) in the diagnosis of aortic arch abnormalities in fetuses with isolated abnormal upper thoracic 3‐vessel view (3VV).MethodA total of 3,420 women underwent a targeted anatomic survey at 18–22 weeks' gestation in a 1‐year period. An isolated abnormal upper thoracic 3VV detected on 2‐dimensional (2D) imaging was followed up by conventional 2D echocardiography and 3D fetal echocardiography with STIC. Offline reconstruction by a second operator blinded to the suspected diagnosis was performed. Neonatal echocardiography and MRI with 3D reconstruction were performed to verify the prenatal diagnosis.ResultOf the 3,420 patients referred, 4 had an isolated abnormal 3VV (0.09%). A right‐sided aortic arch (RAA, n = 3) and double aortic arch (DAA, n = 1) were suspected. In all aortic arch abnormalities, 3D fetal echocardiography and STIC correctly identified RAA with aberrant left subclavian artery in 3 cases and DAA in 1 case with a degree of definition that was equal to the confirmatory postnatal echocardiography and 3D MRI.ConclusionAlthough the 2D upper 3VV is a powerful screening tool for isolated aortic arch abnormalities, 3D fetal echocardiography with STIC allows an accurate prenatal characterization of the abnormality to a degree that is typically attainable only by post partum imaging. © 2009 Wiley Periodicals, Inc.
